Abstract Question In people who have undergone surgical carpal tunnel release, do sensorimotor-based exercises performed on the touchscreen of a tablet device improve outcomes more than a conventional home exercise program prescribed on paper? Design Randomised, parallel-group trial with concealed allocation, assessor blinding, and intention-to-treat analysis. Participants Fifty participants within 10 days of surgical carpal tunnel release. Intervention Each participant was prescribed a 4-week home exercise program. Participants in the experimental group received the ReHand tablet application, which administered and monitored exercises via the touchscreen. The control group was prescribed a home exercise program on paper, as is usual practice in the public hospital system. Outcome measures The primary outcome was functional ability of the hand, reported using the shortened form of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire. Secondary outcomes were grip strength, pain intensity measured on a 10-cm visual analogue scale, and dexterity measured with the Nine-Hole Peg Test. Outcomes were measured by a blinded assessor at baseline and at the end of the 4-week intervention period. Results At Week 4, functional ability improved significantly more in the experimental group than the control group (MD –21, 95% CI –33 to –9) on the QuickDASH score (0 to 100). Although the mean estimates of effect on the secondary outcome also all favoured the experimental group, none reached statistical significance: grip strength (MD 5.6 kg, 95% CI –0.5 to 11.7), pain (MD –1.4 cm, 95% CI –2.9 to 0.1), and dexterity (MD –1.3 seconds, 95% CI –3.7 to 1.1). Conclusion Use of the ReHand tablet application for early rehabilitation after carpal tunnel release is more effective in the recovery of functional ability than a conventional home exercise program. It remains unclear whether there are any benefits in grip strength, pain or dexterity. Trial registration ACTRN12618001887268. [ABSTRACT FROM AUTHOR]

Social life cycle assessment (S-LCA) is a tool to address social impacts from a life cycle perspective. This work presents the first S-LCA of the Portuguese pulp and paper sector. It presents the social risks and the positive social impacts of the sector, which have not been extensively covered in the scientific literature. Two different approaches were used to compile the social life cycle inventory based on input-output analysis. Approach 1 was based on impact analysis of changes in added value. Approach 2 was based on structural path analysis, supporting the disaggregation by production levels (or tiers). The functional unit was the production of 1 United States Dollar in the Portuguese pulp and paper sector. In the social life cycle impact assessment, the social risk assessment was conducted using the Social Hotspots Database. The positive impacts were addressed considering indicators of employment and remuneration, namely total employment, number of employees, labor compensation, and compensation of employees. Based on Approach 1, the results of the social risks showed the Portuguese pulp and paper industry, commerce and forestry sectors, and the Spanish forestry sector as the critical sectors. Based on Approach 2, Portugal and Spain continued to be the countries having the greatest social risks. Other contributions of countries were identified at different production levels, particularly China in tier 3. In both approaches, the stakeholder category 'worker' was the most critical. Regarding the positive social impacts, Approach 1 showed that Portugal and Spain contribute to the highest employment level linked to the pulp and paper, commerce, and forestry sectors. Approach 2 supported the differentiation of employment and remuneration at different production levels. Tier 2 (direct suppliers) presented the highest employment level and persons engaged and the lowest remuneration level. The results showed that Approach 1 provides a faster and more aggregated assessment of social risks and positive social impacts. Furthermore, Approach 2 allowed a more detailed evaluation, providing a better understanding of the social risks and positive social impacts on the supply chain. Thus, Approach 2 is encouraged for different applications since it produces a better understanding of where social risks and positive social impacts occur, providing better guidance for corrective measures and decision-making.

The aim of the study was to perform dimensional, morpho-structural, mechanical and chemical characterization of four materials based on paper currently in use in Romania (RO), Italy (IT), Spain (SP) and Slovenia (SLO) designed for the temporarily wrapping of meat. SEM-EDXS, FTIR and DSC showed that RO is laminated on one side with polyethylene, SP is waxed, IT is modified with a multilayered polyethylene film and SLO is coated with hydrophobized starch. RO, IT and SLO comply with the standards of determination of density, roughness, breaking length and bending resistance. The highest content of metals found in the SP explains the highest electrical conductivity and the poor quality of the recycled material used for manufacturing. The highest values of total dissolved solids (TDS) and chemical oxygen demand (COD) resulted for SP sample expressed its water solubility and availability of migration into foodstuff. RO, IT and SLO are suitable for food packaging. In contrast, SP do not meet the requirements for safety and mechanical resistance. [Display omitted] • Characterization of four types of materials based on paper. • RO, IT-single-face coated with PE, SP-double-side waxed, SLO-coated with starch. • RO, IT, SLO comply the standards of mechanical resistance and are suitable for food packaging. • SP do not meet the requirements for safety and mechanical resistance.

The number of Fuel Cell Electric Vehicles (FCEVs) in circulation has undergone a significant increase in recent years. This trend is foreseen to be stronger in the near future. In correlation with the FCEVs market increase, the hydrogen delivery infrastructure must be developed. With this aim, many countries have announced ambitious projects. For example, Spain has the objective of increasing the number of Hydrogen Refuelling Stations (HRS) with public access from three units in operation currently to about 150 by 2030. HRSs are complex systems with high variability in terms of layout design, size of components, operational strategy, hydrogen generation method or hydrogen generation location. This paper is focused on on-site HRS with electrolysis-based hydrogen production, which provides interesting advantages when renewable energy is utilized compared to off-site hydrogen production despite their complexity. To optimize HRS design and operation, a simulation model must be implemented. This paper describes a generic on-site HRS with electrolysis-based hydrogen production, a cascaded multi-tank storage system with multiple compressors, renewable energy sources, and multiple types of dispensing formats. A modelling approach of the layout is presented and tested with real-based parameters of an HRS currently under development, which is capable of producing 11.34 kg/h of green H 2 with irradiation at 1000 W/m2. For the operation, an operational strategy is proposed. The modelled system is tested through several simulations. A sensitivity analysis of the effects of hydrogen demand and day-ahead hydrogen production objective on emissions, demand satisfaction and variable costs is performed. Simulation results show how the operational strategy has achieved service up to 310 FCEVs refuelling events of heavy duty and light duty FCEVs, bringing the total H 2 sold up to almost 7200 H2kg in one month of winter. Additionally, considering variable costs of the energy from the utility grid, the model shows a profit in the range of 21–50 k€ for a daily demand of 60 H2kg/day and 100 H2kg/day, respectively. In terms of emissions, a year simulation with 60 H2kg/day of demand shows specific emissions in the production of H 2 in Spain of 6.26 kgCO2eq/H2kg, which represents a greenhouse gas emission intensity of 52.26 gCO2eq/H2MJ. • Modelling approach of hydrogen refuelling station with on-site hydrogen production. • Operational strategy with day-ahead scheduled grid-connected hydrogen production. • Finite-state machine online control of a multi-tank and multi-compressor plant. • Sensitivity analysis of hydrogen demand magnitude and frequency. • A trade-off between demand satisfaction, profits and emissions.

Deploying renewable hydrogen presents a significant challenge in accessing off-takers who are willing to make long-term investments. To address this challenge, current projects focus on large-scale deployment to replace the demand for non-renewable hydrogen, particularly in ammonia synthesis for fertiliser production plants. The traditional process, involving Steam Methane Reformers (SMR) connected to Haber-Bosch synthesis, could potentially transition towards decarbonisation by gradually integrating water electrolysis. However, the coexistence of these processes poses limitations in accommodating the integration of renewable hydrogen, thereby creating operational challenges for industrial hubs. To tackle this issue, this paper proposes an optimal dispatch model for producing green hydrogen and ammonia while considering the coexistence of different processes. Furthermore, the objective is to analyse external factors that could determine the appropriate regulatory and pricing framework to facilitate the phase-out of SMR in favour of renewable hydrogen production. The paper presents a case study based in Spain, utilising data from 2018, 2022 and 2030 perspectives on the country's renewable resources, gas and electricity wholesale markets, pricing ranges, and regulatory constraints to validate the model. The findings indicate that carbon emissions taxation and the availability and pricing of Power Purchase Agreements (PPAs) will play crucial roles in this transition - the carbon emission price required for total phasing out SMR with water electrolysis would be around 550 EUR/ton CO 2. • Addressing the co-existence of steam methane reformers and electrolysers. • Novel power dispatch model addressing the flexibility of co-existential pathways. • PPA availability and pricing and ETS taxation as key enablers of renewable hydrogen. • Carbon intensity constraints heavily impact the project's sizing and feasibility. • Techno-environmental study of the carbon intensity of ammonia production.

This paper examines the uppermost Sinemurian and lowermost Pliensbachian ammonite fauna recorded in NW Iberia with a special focus on Echioceratidae from the Aplanatum Subzone. In total, 852 specimens have been collected bed-by-bed from five reference sections from the Asturian, Basque-Cantabrian, and Lusitanian basins. Echioceratidae, namely Paltechioceras genus, represent 86.2% of the sample, Polymorphitidae (Leptonotoceras genus) the 10%, and less than 4% of the specimens are Eoderoceratidae, Phricodoceratidae, or Oxynoticeratidae. This study describes five species of Paltechioceras , namely P. tardecrescens , P. oosteri , P. recticostatum , P. elicitum , and P. romanicum. They allow a biochronostratigraphic division for the studied basins and its worldwide correlation. One of the species, P. romanicum , is the latest one registered in all the studied sections, occurring directly below the Sinemurian–Pliensbachian boundary. The disappearance of this widely distributed species marks the echioceratids extinction. This work reviews the global events described around the Sinemurian–Pliensbachian transition (the Sinemurian–Pliensbachian boundary event). Finally, we present a palaeobiogeographical analysis of the Paltechioceras species described, giving more information to discuss the opening of the Hispanic Corridor during the late Sinemurian.

The Spanish passenger railway market saw the entrance of two competitors in 2022–2023: the full-service operator Iryo and the low-cost operator Ouigo. Using a unique dataset of Spanish ticket price collected throughout an entire year and the Diff-In-Diff method, this paper investigates the impact on incumbent's prices of newcomers' entrance on the less congested corridors Madrid - Alicante and Madrid - Malaga/Sevilla. The Spanish government's strategy seems to be successful: the decision to lead the liberalisation process and the choice of having up to three asymmetric competitors induced a significant decrease in price even on the less attractive corridors, stimulating the demand and addressing the problem of under-utilization of some high-speed infrastructure. The results show that prices decreased by 28%–30% after nine months of competition. The impact has been the same on both the analysed corridors, despite the competition environment has been different in terms of number of competitors, pricing strategy and market share of those. • Spain is the first country with three competitors in the high-speed railway market. • Competition in high-speed rail in Spain reduced prices by 28%–30% in nine months. • The impact on incumbent's first-class and second-class prices was the same. • Both low-cost and full-service competitors similarly affected incumbent pricing.

The MMR vaccine was included in the official vaccination schedule in Spain in 1981. Currently, most women of childbearing age are vaccinated and have not been naturally infected. Several studies have shown that vaccinated women have a lower antibody concentration than that achieved after natural infection, and a shorter duration of transplacentally acquired antibodies in their children. The objective of this study was to determine the antibody titer in mothers and their infants at birth and throughout the first year of life under current epidemiological circumstances. Single-center, observational, descriptive and prospective study conducted between October 2013 and December 2014. One sample of serum and another of a dried blood spot on filter paper were taken from each mother. Dried blood spot samples on filter paper were taken from the children at birth, and at 3, 6, 9 and 12 months. In all the samples, levels of antibodies to the measles, rubella and mumps viruses were measured using standardized quantitative assays. 146 mother-child pairs were included. 78.4%, 86.9% and 67.1% of mothers had antibodies to measles, rubella and mumps, respectively. A decrease in the antibody titer in children was observed after 3 months, and no antibodies against the three diseases were detected by the age of 6 months. Comparisons revealed no statistically significant differences between the antibody titers of children of mothers born before or after 1981 during the first year of their life. The rapid loss of transplacentally acquired antibodies against measles, rubella and mumps, under current epidemiological conditions, suggests that bringing the MMR vaccination forward to 9 months might be justified. Larger population studies are needed to confirm these results. [ABSTRACT FROM AUTHOR]

The prevalence of depression related to precarious employment (PE) has become a significant public health concern, given the declining trend of the standard employment relationship. Research has focused on the mental health detrimental effects of employment conditions, whereas there is scarce evidence concerning the burden of depression that could be prevented by targeting precariousness. This paper estimates the impact of PE on the risk of depression and the attributable fraction within the active and working salaried population in Spain. Observational cross-sectional on data drawn from the Spanish portion of European Health Survey 2020. After applying selection criteria and descriptives, binary logistic regression models stratified by sex are used to examine the associations between a 9-categories combination of employment precariousness and occupational social class, and depressive symptoms. There is a higher risk of depression among individuals in PE and among those who are unemployed, with a notable gradient based on occupational social class for women. Adjusting by sex, age and foreign-born origin, we estimate that approximately 15.0% (95% confidence interval [CI]: 1.0%–26.2%) of depression cases among the working population and 33.3% (95% CI: 23.2%-43.2) among the active population can be attributed to PE. These findings highlight the public health impact of PE on mental health, provide evidence to estimate the economic burden linked to employment-related mental health, and underscore the need for policy changes and interventions at the level of labour markets and workplaces to mitigate the detrimental effects of PE.

The demand for eco-products due to the exigency of friendly and environmental production could affect the employment of the firms. This paper tests whether product and process eco-innovations boost employment in Spain differentiating by the environmental goals (material and energy efficiency and environment responsiveness), by the level of qualification of the workers, and by the dirtiness of the industries. We apply a Green Harrison model, using the Technological Innovation Panel (PITEC) for Spain from 2008 to 2016. Results show a positive relationship between all types of product eco-innovations and employment, while the influence of process eco-innovations on employment depends on the environmental goals, the level of skills, and the industry. Specifically, distinguishing by industry there is a labour-saving effect in clean industries and a labour-friendly effect for low-skilled employment in dirty industries. [ABSTRACT FROM AUTHOR]

• Innovation has been quantified with patents and significant innovations. • Innovation occurred in waves as Schumpeter indicated. • Major innovations were followed by incremental advances. • Process innovation predominated at first, followed by product innovation. • Indigenous innovation favored the absorption of foreign technology. Although Spain was not a leading country in technology, it generated numerous innovations, which must be analyzed in order to understand its particular development trajectory. This paper makes a contribution in this line by quantifying the innovation activity of the country's business elite between c. 1870 and 1970. In addition, we have sought to verify whether some of the well-known debated dynamics of innovation over time are fulfilled in this case. First with a descriptive analysis and then through the VAR technique, it has been found that innovation occurred in waves, as Schumpeter pointed out despite Kuznets; major innovations were followed by incremental advances; process innovations predominated in the early stages of modern development and product innovations gained preponderance later; and that indigenous innovation favored the importation of technology. A structural break test has identified sharp fluctuations in innovation, apparently related to institutional factors and relevant changes in the economy. [ABSTRACT FROM AUTHOR]

To determine the institutions, journals of choice and topics of investigation of the most prolific and highly cited Spanish optometrist researchers. As a primary search strategy, the Scopus database (Elsevier) was queried with the terms (optometr* OR "contact lens*" OR refracti* OR *ocular) and the affiliation country filter "Spain". The list of authors returned by the primary search was used in a secondary manual search based on co-authors and institutions. Authors were included in the analysis if they had an h-index > 10, were of Spanish nationality, were affiliated to Spanish institutions, and possessed an optometry degree. Authors were ranked by h-index, number of publications and number of citations. Topics of research interest and target journals were determined by analyzing the 10 most highly cited papers of each author. A total of 32 authors with an h-index > 10 were identified, of whom 14 (43.7%) were female. Only one author had an h-index > 40, and 7 (21.9%) authors had an h-index over 20. The Journal of Cataract and Refractive Surgery was the first journal of choice (19.1% of highest cited papers), followed by Optometry and Vision Science (10.3%). The Universidad Complutense de Madrid hosted the largest percentage of authors (18.7%), followed by the Universitat de València (15.6%). Main topics of research interest were topography (6.5% of papers), cornea (6.2%) and contact lens (5.0%). Optometry in Spain is a fertile field of research, with an increasing number of highly cited authors publishing in high impact journals. [ABSTRACT FROM AUTHOR]

Social innovation (SI) has been championed as an integral feature of community-led rural development. However, the choice of the term "innovation" prompts a number of questions about the intensity and novelty of SI initiatives. In this paper, these issues are examined through the lens of radical and incremental innovation theory. By analysing features of radical and incremental SI, we can better understand the different social reconfigurations that can respond effectively to a range of rural needs and opportunities. The article aims at explaining the meaning and operationalisation of radical and incremental SI in rural areas. A multiple case study method was adopted for the research. Empirical data was gathered from two initiatives located in rural areas of Spain and Scotland and the main methods used were semi-structured interviews and qualitative content analysis. The findings illustrate how radical and incremental SIs can lead to sustainable development and social change. However, they imply social reconfigurations of different intensity that respond to the different attitudes and aspirations of the actors involved. The paper shows three diverging development trajectories for SI initiatives and discusses the role of conflict, skills and planning in these processes. Further, the more fluid nature of SI compared to technological innovation is clarified. In the conclusion we argue that public actors should identify the different aspirations of local actors and set the stage for the activation of the local society. In radical SI processes, conflict management mechanisms and new skills need to be promoted. • The intensity of social innovation (SI) in rural areas is examined through the lens of radical and incremental innovation. • Actors' attitudes and aspirations in relation to community needs influence the degree of radicalism of SI. • The way SIs challenge the status quo of local communities is key in distinguishing radical and incremental processes. • Radical SI usually requires longer adoption periods and can bring about conflicts. • The emergence of conflicts depends on the temporal context and the specific nature of the actors involved. • SI initiatives are fluid and can evolve into different radical and incremental processes over time.

• Significant reduction (18.44%) in overall Spanish GHG emissions from 2008 to 2018, highlighting some differences depending on the considered phase of the crisis. • The total intensity effect has been noticeable negative, especially in Agriculture, Transport, and Other Services. • The total carbonization effect has contributed to increase GHG emissions by 5.86%, being particularly negative in the case of Industry. • Per capita production effect was strongly negative in Industry and slightly positive in the rest of the economic sectors. • R&D, more eco-friendly technologies, green energies, circular economy and consumer green attitudes: the best strategies to reduce GHG emissions. The reduction of GHG emissions to reverse the greenhouse effect is one of the main challenges in this century. In this paper we pursue two objectives. First, we analyze the evolution of GHG emissions in Spain in 2008–2018, at both the global and sectoral levels, with the variation in emissions decomposed into a set of determining factors. Second, we propose several actions specifically oriented to more tightly controlling the level of emissions. Our results showed a remarkable reduction (18.44%) in GHG emissions, mainly due to the intensity effect, but also to the production-per-capita effect. We detected somewhat different patterns among the various sectors analyzed. While the intensity effect was the most influential one in the agricultural, transport, and others sectors, the production-per-capita effect was predominant in the case of industry. The carbonization effect was revealed as crucial in the commerce sector. The above findings highlight the importance of the energy efficiency measures taken in recent years in the Spanish economy, also pointing to the need to deepen those strategies and to propose new measures that entail greater efficiency in emissions. Additional efforts in areas like innovation, R&D, diffusion of more eco-friendly technologies, and a greater use of greener energies all prove to be essential reduction actions to fight the greenhouse effect.

The electricity production from Renewable Energy (RE) in isolated locations requires long-term energy storage systems. To that end, Hybrid Energy Storage Systems (HESS), through a combination of hydrogen and batteries, can benefit from the different advantages of both technologies. This paper presents a hybrid Power-to-Power (PtP) Optimal Power Dispatch (OPD) model for isolated systems with no electric grid access. Currently, the electricity supply in such cases is usually based on a mix of RE as the primary energy source sustained by a diesel genset acting as a backup generator. In this context, the model delivers the hourly energy flows between renewable production sources, energy storage devices and the electrical load, which minimises costs and Green House Gases (GHG) emissions. For validation purposes, the model was tested through its application to a case study in an isolated area in the Canary Islands, Spain. The results show that the algorithm calculates the hourly OPD successfully for a given plant sizing, considering the defined operational states of the different assets. These operational constraints showed a decrease in the PtP round-trip efficiency of 5.4% and a reduction of the hydrogen production of 9.7%. Finally, the techno-economic analysis of the results proves that the combination of hydrogen and batteries with RE production is a feasible alternative to phasing out fossil fuels for the selected case study – reducing the diesel generator usage down to 1.2% of the yearly energy supply. • Novel multi-state optimal power dispatch model for power-to-power energy systems. • Multi-year techno-economic evaluation of an off-grid case study. • Phasing out fossil fuels with renewable energy-based hybrid energy storage systems. • Hydrogen technology contributes to a lower levelized cost of energy. • High initial investment cost was a significant entry barrier to deploying hydrogen.

So far in the literature, the two-parameter Weibull distribution and its other extensions are frequently implemented to analyze the wind speed energy data sets. However, based on our study of the literature, there is no published work about analyzing the wind speed energy data sets using new probability distributions that are developed via trigonometric functions. In this paper, I attempt to cover this amazing and interesting research gap. Therefore, I incorporate a trigonometric function, especially, the sine function to introduce a new statistical distributional method. The proposed method is called a new modified sine- G family of distributions. Some distributional properties of the new modified sine- G method are obtained. Using the new modified sine- G method, a new extension of the Weibull distribution called a new modified sine-Weibull distribution is studied. The new modified sine-Weibull distribution is applied to analyze four wind speed energy data sets. All three data sets are taken from the weather station at Sotavento Galicia in the Canary Islands, Spain, located at 43.3544 North and 7.8812 West. [ABSTRACT FROM AUTHOR]

Food security is one of the main challenges for the future. Expectations from UN indicate that it is necessary to double food production in the next years. This means that water needs will grow more than expected and the use of the non-conventional water resources will be absolutely crucial. Desalination for agriculture is almost irrelevant globally, although countries such as Spain have demonstrated that desalination can be used for supplying an agriculture based on high added value crops. In this paper we will analyze this application with the experiences and knowledge acquired in the last years, including the history of desalination for agriculture, technical and economic aspects, success stories and innovation. It is also remarkable that farmers from the Southeast of Spain (Mediterranean Coast) have established a very efficient irrigation system which is fed by a blending of water from different origins obtaining in this way a good quality water with affordable prices. In the field of innovation, 2 main projects related with agriculture will be shown; LIFE DESEACROP, which was developed to demonstrated the feasibility of the use of desalinated water for agriculture and SOS-AGUA-XXI, a 6 Million € R&D project funded by Spanish Government with European Funds.

This paper examines the selection mechanism underlying the association between overweight/obesity and educational aspirations of adolescents. This is a cross-sectional study based on a survey conducted in secondary schools in Spain in 2016. We estimate linear probability models to determine the association between adolescents' body mass index (BMI) and their expectations to obtain a university degree, as well as their school choices representing the most usual path towards higher studies. To address the potential endogeneity of BMI, we use the instrumental variables (IV) method. Additionally, we account for potential unobserved heterogeneity by including school fixed-effects and a wide set of individual and family characteristics in our analysis. Our results indicate that adolescents with a higher BMI have lower expectations to obtain a university degree and are less likely to enrol in high school with the intention to pursue higher education in the future. The estimated effect is quite sizable and statistically significant only for girls. We estimate that a five-unit increase in BMI (e.g., the change between healthy weight and overweight) reduces girls' expectations to complete higher education by 19 percentage points and odds of enrolling in high school (vs. vocational training) by 21 percentage points. We provide empirical evidence supporting the selection hypothesis behind the relationship between BMI and adolescents' educational aspirations. That is, unhealthy weight in adolescence is associated with poorer aspirations for further education. Lower educational aspirations during adolescence can lead to lower academic achievement, which in turn, may result in poorer health, labour market outcomes, and well-being during adulthood.

The present article reviews the Spanish history of the art therapy profession and research. In addition, a contemporary view of current art therapy research is described through a bibliometric analysis of 160 art therapy articles published in the Spanish Journal of Art Therapy. Papers on Art Therapy and art Education for Social Inclusion from 2011 to 2021. The following research indicators were analyzed: authorship, participants, population, artistic discipline, theoretical models of art therapy intervention, nature of the studies, and assessments. Outcomes revealed that Spanish art therapy researchers are mostly women who usually publish on their own. Additionally, many ages, populations and topics are treated. Visual art is the discipline most used in the analyzed research. Gestalt, community-based art programs, and the eclectic approach are the most selected theoretical models. Most of the studies are qualitative and theory building with no assessment. However, when assessment is included, the type most used is the tools made by the researcher. Implications, limitations, and further lines of research are discussed. • Art therapy research in Spain is a young discipline conducted in the last ten years. • The profile of Spanish researchers on art-therapy corresponds to dedicated females. • The use of art therapy in Spain has extended to vulnerable and minority groups. • There is a shift from psychoanalysis to other theoretical models for intervention. • Most of the studies published in Spain are qualitative or theory building.

• Mechanisms to encourage clean energy in Spain from 2005 to the present are analyzed. • FiT and FiP mechanisms can be effective in promoting new renewable projects. • Experience suggests that excessive support can jeopardize the entire market. • A transitional retribution scheme has proven to be effective if correctly supervised. This research paper delves into the central mechanisms implemented in Spain to foster the adoption of clean energy projects. The study scrutinizes various mechanisms established from 2005 onwards, evaluating their efficacy in achieving the desired outcome of supporting clean energy project implementation. The aim is to comprehensively assess the associated costs, effectiveness, and attainment of renewable energy objectives stemming from implementing diverse support schemes. This paper explores the effectiveness of feed-in tariffs and feed-in premium mechanisms in promoting the integration of new renewable energy generation into the power system. However, the Spanish experience suggests that exhaustive planning control is imperative to prevent excessive support costs that could jeopardize the entire market and cause a significant rise in final energy costs. The research studies the support schemes and associated market distortion and presents the roadmap from regulated tariffs to a "total market" for wind and solar energy. The findings demonstrate that, under proper supervision and planning, a transitional retribution scheme effectively promotes renewable energy plant integration. Finally, the analysis examines the need to regulate the excess benefits that non-emitting power sources receive in a marginal price market, as this can lead to market imbalances and a substantial increase in final costs. These plans serve as a crucial tool in achieving the decarbonization objectives of the European Power System. [ABSTRACT FROM AUTHOR]

• Pioneer Spain: first country to include in grid code the synthetic inertia capability. • Synthetic inertial response of a PV inverter studied based on the Spanish grid code. • Analyzed the role of power plant controller in the dynamic response of the facility. • PV system able to contribute to frequency control providing an inertial response. As the large-scale integration of renewable energy grows, inertia in power systems is reduced, which causes the rate of change of frequency to increase and worsens the frequency nadir during disturbances. There is, therefore, an urgent need to accelerate the development of international standards and regulations that require solar PV systems and other renewable installations to also contribute to stability in the network by emulating inertia. Spain is a pioneer in this field: it is currently the only country that includes the synthetic inertia technical requirement in its grid code. In this context, the present paper analyzes the synthetic inertial response of a PV system model that forms part of an actual PV power plant in Spain under two scenarios, according to its grid code: i) when measurements are conducted at the power conversion PV system level and hence only its control algorithms are executed; and ii) when measurements are conducted at the power plant level and the power plant controller also influences the response of the entire installation. Among its aims, this paper seeks to thoroughly assess the response of an actual PV power conversion system that has the capability of actively contributing to frequency regulation in a network and to critically analyze the suitability of having a power plant controller when the PV facility contributes to power-frequency control by means of an inertial response. The results reveal, at the power conversion PV system level, that the inertia emulation module significantly reduces the response times of the installation to changes in frequency -by more than 68% in the worst case under frequency increases, and by 73% under frequency decreases, thus contributing to more rapid power-frequency regulation in the network. However, at the power plant level, the power plant controller disturbs the PV power conversion system's behavior and causes the opposite effect: response times increase -up to more than 7% in the most unfavorable case when the inertia module is enabled.

This paper investigates Spanish drivers' perceptions of the main barriers existing in Spain to the purchase of zero-emission vehicles (ZEVs). Following a comprehensive literature review in this field, this paper quantifies, by means of a survey conducted in Spain of 1474 Spanish drivers, the drivers' desired levels for each barrier to consider ZEVs in their next purchase decision to replace their current usually-used car. The analysis of these reported levels with latent class cluster models revealed the existence, in the sample, of groups of consumers with homogeneous preferences regarding the barriers. These groups differ in terms of individuals' characteristics, the car to be replaced, and journeys made with it. The most flexible groups comprise individuals with a significant knowledge of ZEVs, which underscores the importance of educational policies for the promotion of the use of ZEVs. The desired levels of the barriers for each group are confronted with the current status of the barriers for certain ZEVs. This comparison reveals that Fuel Cell Electric Vehicles (FCEVs) would have great potential if they received government support, because their only barriers are economic (purchase price and fuel availability). This paper also quantifies the effects that purchase incentives and infrastructure investment policies could have in terms of higher FCEV penetration rates. [ABSTRACT FROM AUTHOR]

Edward Jenner's discovery of the smallpox vaccine spread rapidly across Europe. In Spain, vaccinations first took place in December 1800 and the practice flourished upon the private initiative of doctors, surgeons, state officials and members of the nobility in different parts of the country. Ignacio María Ruiz de Luzuriaga, secretary of the Royal Academy of Medicine of Madrid, is considered in medical historiography as a key figure of the introduction of the smallpox vaccine in Spain. Ruiz de Luzuriaga had a major role as a disseminator of the Jennerian technique and as a distributor of the vaccine fluid. Given his prestige as a doctor and his position in the Royal Academy, he was commissioned to establish a scientific and academic corpus on preventive measures to foster their understanding, uptake and good practice among Spanish vaccinators. He also attempted to create a Central Vaccine Committee, such as that existing in other European countries. The Royal Academy kept records of his activity which have been filed and catalogued in a documentary set entitled 'Papeles sobre la vacuna' [Vaccine Papers]. This archive has not been studied in depth to date. These documents allow identifying a network of correspondents set up by Ruiz de Luzuriaga. He provided these correspondents with the vaccine and asked them to report back on the vaccination progress made in their municipalities. This correspondence provides an account of how the first immunisations in Spain unravelled, as well as of the initial concerns that accompanied the introduction of the vaccine.

• GNSS-PWV time series are computed using 44 GNSS stations in Andalucía and ERA5 temperature and pressure data. • GNSS-PWV and ERA5-PWV are used to compute SPCI time series. • The SPCI generally shows high correlation with the SPEI, with better results for ERA5-SPCI than GNSS-SPCI. • The SPCI outperforms SPI for a limited geographical region and 24-month timescale. In this paper the Standardized Precipitation Conversion Index (SPCI), a PWV-based drought index, has been computed using GNSS and ERA5 PWV and its performance has been tested with respect to the Standardized Precipitation Evapotranspiration Index (SPEI) in Southern Spain. One of the climatic features of this area is the low correlation level between PWV and precipitation, in contrast with other areas in which SPCI has been previously tested. The GNSS-SPCI has been derived from validated ZTD time series estimated from local GNSS permanent stations' data. All the needed meteorological values were derived from ERA5, excepting precipitation values and SPEI-SPI values which were extracted from a national high-resolution dataset. The resulting SPCI time series have shown high correlation coefficients with respect to the SPEI. The use of longer SPCI time series allowed by ERA5 model has provided the most coherent results, suggesting that the ERA5-PWV data can be interesting to overcome problems caused by the short timespan of GNSS time series in SPCI computation. In general, high correlation coefficients have been obtained compared to global results from previous studies. This shows that, even for regions with low correlation levels between PWV and precipitation, the SPCI can have an interesting potential for drought monitoring. The SPCI was found to perform better on higher timescales (12 and 24 months). The performance of SPCI has also been compared that of the SPI: SPCI is able to outperform SPI for the 24-month timescale for a limited geographical region. This supports that the inclusion of PWV data in drought monitoring indices could be promising and is worth keeping to be investigated. [ABSTRACT FROM AUTHOR]

Considering the impact of photovoltaic installations and the fact that their performance depends on the type of day, this paper presents a classifier that makes use of fuzzy logic to classify daily irradiance profiles as a human would do. To do this, the system must be linguistically interpretable, so the classifier must be simple enough, but without losing accuracy. This is why the article combines the use of data mining and supervised learning algorithms to obtain an initial system and then exploits simplification techniques such as the concept of fuzzy classifiers with incomplete rule bases, as well as fuzzy tabular simplification of rules to obtain a compact and simple final system. The classifier obtained handles the ambiguity presented by the daily irradiance profiles with precision. Once the system has been obtained, a large number of days in southern Spain are classified, analysing the performances of a photovoltaic plant obtained in each of the classes. Then, a neuro-fuzzy system is designed to predict the performance of the photovoltaic installation, considering the type of day, the maximum ambient temperature reached during the day, and the degradation of the installation over time, proving its usefulness in alerting about anomalous behaviour of the system.

• Mining has a high level of serious accidents compared to all other sectors. The analysis is based on 15,032 accidents. • 12 variables are studied and the influence of each variable on the severity, which is divided into three types (light, serious and fatal). • The results make it possible to design prevention measures for the situations that have led to the most serious accidents. Introduction: The aim of this paper is to understand the causes of occupational accidents in Spain's mining sector in order to propose action plans and improve future accident rates. Method: This research analyzed a pool of data on 15,032 accidents occurring in the mining sector and reported to authorities between 2013 and 2018. Accidents are divided into three levels of severity: light, serious, and fatal. We study the influence of 12 variables on the accident severity rate in our sample. Results: The results show that accident severity is related to age, gender, nationality, length of service, economic activity, company size, accident location, days of injury leave, day of the week, deviation, injury, and specific Spanish region. This sector produces a high rate of serious accidents compared to all other sectors; has a male-dominated, older and experienced workforce; and employs mainly Spanish workers. Its activity is concentrated in larger companies and the work involves the use of heavy machinery and dangerous materials. We offer conclusions and future lines of research to help regulators, companies and workers to improve worker safety. [ABSTRACT FROM AUTHOR]

• Analysis of several factors that may be behind an undue extension of the injured worker's recovery time. • Comprehensive empirical analysis of more than 400,000 non-fatal work accidents in manufacturing industries. • Women, workers with more seniority, higher wages, and those employed in larger companies take longer to return to work after an occupational injury. • The duration of sick leave for immigrant workers is lower than for native-born workers. • Improving working conditions and supervision mechanisms during the recovery process is recommended to increase attendance motivation and reduce moral hazard exposure. Introduction : Despite the significant economic impact of occupational injuries on companies and society, studies focused on analyzing the determinants of workdays lost due to sick leave remain scarce and incomplete. This paper contributes to this issue by (a) analyzing the drivers of sick leave duration, distinguishing factors that explain the health recovery time from those that could lead workers to a voluntary extension of the absence period, and (b) formulating and empirically testing the effect of gender, citizenship, temporary work, job tenure, amount of disability benefit, and size of the injured worker's firm on the number of days the employee is off work after the injury. Method: Hypotheses are tested on a comprehensive dataset that includes all nonfatal occupational injuries causing sick leave that occurred in the manufacturing sector in Spain during 2015–2019, with more than 400,000 injuries. We conduct ordinary least squares and count data regression models in which the number of days off work is regressed on employees and work characteristics while accounting for a set of variables to control the injury's nature and severity. Results: The results show that after considering the intrinsic characteristics of the injury and the severity of the worker's injuries, women, native workers, workers with more seniority, workers with higher salaries, and those working in larger companies have longer periods of sick leave. The results suggest that moral hazard considerations significantly impact the time to return to work after an occupational injury. Practical applications: Based on the findings, several insights for company managers and public decision-makers are discussed. Specifically, interventions aimed at improving the organization of work and the working conditions of workers in manufacturing industries are highlighted, as well as the need to improve control and supervision mechanisms during the recovery process of injured workers.

• This paper contributes to the literature that looks at decentralisation as an institutional solution to curb instability and secessionist pressures.· The ability of decentralisation to deter secessionism depends on the institutional form it can take. • A bottom-up reform may be more successful in avoiding a secessionist conflict than a more standard top-down decentralisation. • The theoretical framework of this paper can shed light on the decentralisation reforms recently adopted by different countries. This paper looks at decentralisation as an institutional solution for curbing secessionist pressures by making potentially seceding regions strictly better off by staying in the union. We show that a bottom-up decentralisation reform, where single regions that can opt to assume or not stronger fiscal responsibilities on the basis of bilateral negotiations with the central government, may be more successful in avoiding instability and a secessionist conflict than more standard top-down decentralisation, where the central government assigns identical fiscal powers to all regions. The example of the decentralisation process in Spain over the last 40 years illustrates the relevance of the institutional pattern we analyse in the paper. [ABSTRACT FROM AUTHOR]

The EU has set itself demanding objectives to achieve complete decarbonisation by 2050. The building sector plays an important role for this purpose, hence monitoring its progress towards decarbonisation is essential to identify measures that work and to readjust policies when necessary. However, collecting information to monitor the building sector is a complex task due to the scarcity and low quality of available data. The European digital building logbook (DBL) has great potential in this regard because it allows the collection of data at the building scale, which could be combined at a national level. Thus, this paper proposes a new functionality for the DBL -as an enabler for the collection of data for the assessment of the progress of the main EU policy objectives related to the building sector decarbonisation-, and it evaluates the potential of the DBL for it. To do so, the main policy objectives were associated to a set of progress indicators –mandatory and optional- and matched to DBL indicators. Mandatory indicators are for all Member States and they have been included in the 2023 amended version of the proposal for the Energy Performance of Buildings Directive recast. Optional indicators are considered country-specific in this paper and are sourced from various literature references. Here we have studied the optional progress indicators for the case of Spain. Results show that the DBL has great potential to contribute to the collection of more than half of the mandatory indicators and a very high share of the optional ones for Spain. • Monitoring the decarbonisation progress of national building sectors is crucial. • Mandatory and optional indicators are needed to monitor buildings decarbonisation. • The DBL has great potential for monitoring national building stocks decarbonisation. • The DBL will provide the majority of the decarbonisation progress indicators.

Soil aquifer treatment (SAT) is a managed aquifer recharge technology that involves the utilization of treated wastewater as a source. Widely implemented in countries like Australia, Israel, and Spain, SAT offers technical (flexibility), economic (lower investment cost), and environmental (lower energy consumption) advantages that invite people in other countries to assess its potential. There have been numerous research studies and experiments conducted on the process level of SAT, focusing on how to eliminate pollutants and improve water quality. However, research at the system level is limited, which hampers its widespread application, especially in developing countries. In this paper, I provide a comprehensive guideline that highlights important factors to consider when implementing SAT as a technology. Proper site selection and careful planning steps, including pretreatment, hydrogeological factors, and economic calculations, can significantly improve the performance of an SAT system. The regulatory component acts as a barrier to the expansion of SAT facilities worldwide due to the lack of harmonization in regulations. This study includes the details and results of an examination of the legal framework and establishes comparative guidelines and water quality parameters that must be met by SAT projects utilizing reclaimed water. The maintenance and monitoring of the SAT system are also essential to anticipating and addressing potential issues such as clogging. Lastly, the social aspect, which is of utmost importance, should be carefully considered. It is advisable to ensure transparent communication with end users from the early stages of the project. These key elements are interconnected, and none should be considered less significant than the others. [ABSTRACT FROM AUTHOR]

The contribution of this paper is twofold: 1) it develops a replicable socio-hydrology-inspired model that elicits agents' preferences while accounting for the two-way feedbacks between complex human and water systems; and 2) it integrates the resultant socio-hydrology model into robustness-based frameworks to inform the adoption of policies that show a satisfactory performance under most plausible futures. The socio-hydrology model is used to produce a database representing multiple plausible futures that quantifies uncertainty regarding scenario assumptions under alternative adaptation strategies. Using a robust decision-making framework, the mechanistic outputs from the database of plausible futures are combined with heuristic methods through experts' knowledge and opinion to co-design scenarios, identify vulnerabilities and quantify tradeoffs of proposed strategies, and subjectively propose new scenarios and choose the preferred adaptation strategy. Methods are illustrated with an application to the Cega Catchment in central Spain, one of the few major catchments in central Spain that remains non-regulated, and where the construction of a major dam has been projected. Following a robust decision-making process informed by our socio-hydrology model and involving all key parties to the decision, the status quo strategy (no dam construction) was revealed preferred. • We mainstream socio-hydrology modeling into robustness-based decision-making frameworks. • Socio-hydrology modeling quantifies impacts and uncertainties for selected strategies. • Models are combined with experts' knowledge and opinion to identify robust strategies. • Methods are illustrated with an application to dam construction in the Cega Catchment (Spain). • The status quo strategy (no dam construction) was revealed preferred.

Spain is one of the front runners of the development of Concentrated Solar Power (CSP) projects. In recent years, however, the CSP industry in Spain has faced significant financial challenges due to a dramatic withdrawal of the Feed-in-Tariff (FIT) in 2013. The primary aim of this paper is to assess when, and under what conditions, CSP projects, in particular, Parabolic Trough Collectors can potentially reach grid parity in the absence of any subsidies. This paper also goes further to investigate whether and how Parabolic Trough Collector (PTC) projects can be financially viable in the post-subsidy period, using the System Advisor Model as a simulation tool to conduct techno-economic analyses. The simulation results indicated that a 50MWe PTC project with TES of 4 hrs and a PPA price of €0.20 per kWh is the most viable model for developing CSP projects in Spain under post-subsidy condition. This paper concludes that, under current retail electricity prices and post-subsidy conditions, PTC projects can reach grid parity and become viable without direct incentives. Even though direct incentives will not be required, the CSP industry in Spain is still far from becoming fully self-sustained. [ABSTRACT FROM AUTHOR]

Decreasing greenhouse gas emissions plays a crucial role in the Europe energy transition and the production of hydrogen using electricity from renewable sources (green H 2) contributes significantly to this objective. As the renewable energy production capacity grows, the impact of green H 2 is likely to increase. In the case of the Iberian Electricity Market (MIBEL), no quantitative studies have so far tested the viability of the H 2 growth plans. This paper fills this gap through a novel mathematical programming model, which integrates H2 generation into the MIBEL. The model reveals a mismatch between the sustainability goals and the expansion plans of renewable and green H 2 for Spain and Portugal. [Display omitted] • Mathematical Programming to analyse green hydrogen production in the MIBEL. • Influence of the electricity market on hydrogen production and prices. • Generating green hydrogen is preferable to hydro pumping. • Green hydrogen integration might entail additional emissions. • MIBEL hydrogen strategy must be revised to achieve sustainability.

The alternation between cloudy and clear skies alters the photovoltaic production. This makes it necessary to anticipate these disturbances hours in advance for the correct operation of the electricity distribution plants and networks. In this paper, two short-term forecasting models (3 h) are developed to forecast the photovoltaic production in an integrated plant in the CIESOL building of the University of Almería. The methodology used is based on sky camera images and Artificial Intelligence techniques. Two models have been developed and compared applying artificial neural network (ANN) and support vector machine (SVM) techniques. The global irradiance predicted using sky camera images is used as an input variable in both models. In addition, the operational status of the plants has been included as an input parameter through the performance ratio. The results have shown that the errors made by ANN and SVM are very similar. For all sky conditions, the uncertainty of the production forecast differs by less than 2% from the uncertainty of the solar resource, which is the main source of error in the production models developed.

Solar cells lose efficiency as the operating temperature increases under normal operating conditions, resulting in a very significant power output reduction. This issue is most relevant in areas with the highest photovoltaic energy harvesting potential, where irradiance and ambient temperature are particularly high. A novel cooling system for commercial photovoltaic modules based on low-enthalpy geothermal cooling is proposed in this paper. Excess heat is evacuated from the solar module in a clean and efficient manner by a single-phase and close-loop cooling circuit that uses the underground as a natural heatsink. In addition, a thermoelectrical theoretical model is presented, that allows the optimization of the flowrate and the maximization of the extra power generation of the cooled module. A prototype was manufactured and tested in outdoor conditions in September 2021 in Spain. Test results are in good agreement with the theoretical model, which has been used for prediction of the performance of the system for a typical meteorological year in the region. A peak efficiency improvement of 10.7% is calculated for the month of July, with an optimal flowrate of 1.8 l/min per square meter of solar module. A yearly weighted average power gain of up to 4.9% is also calculated. [ABSTRACT FROM AUTHOR]

Shared electric kick scooters (SEKS) have become widespread in many cities worldwide with great expectations from both users and municipalities. Most cities have not yet passed specific legislation to regulate this new phenomenon, thereby increasing uncertainties across different players such as users, operators, etc. This research provides guidelines for regulating SEKS in urban areas for their successful implementation, taking advantage of a collaborative approach with expert stakeholders that look at the regulation problem from different perspectives. The study focuses on the case of Spain where SEKS have been booming over the last few years. The methodology applied follows a three-step process consisting of the identification of crucial issues and key expert stakeholders, a general survey to them, and a final focus group intended to reach consensus. The paper provides regulatory recommendations in four main areas: market access, technical requirements, traffic and safety, and supervision. It finds large agreement on key aspects such as promoting a homogeneous regulation across the municipalities within the same metropolitan area; establishing fixed bases for parking in the city centre while allowing free floating in low density areas located in the outskirts; and promoting an integration with the public transportation system. • Identification of key regulatory aspects for shared electric kick scooters services. • Collaborative approach with key expert stakeholders: survey and focus group. • Regulatory recommendations for shared electric kick scooters in urban areas.

In 2020, the Conference of Chemical Engineering Directors and Deans (CODDIQ) proposed the creation of an observatory to monitor chemical engineering degrees in Spain. This representative radiography of Chemical Engineering studies offers an initial point to observe the future changes when Royal Decree 822/2021 and proposed challenges in the last Ministerial Conference on the European Higher Education Area (EHEA) will be implanted. The survey data from CODDIQ partners allow us to know important data such as (i) the 24 international quality accreditations at Spanish universities, (ii) the high demand and the required marks, an average of 7.25, for the Chemical Engineering Bachelor's degree, (iii) 9560 undergraduate students in this degree in Spain and their gender profile which is around 43% of women, similar than women lectures, (iv) the difficulty of this Bachelor's degree through some indicators like duration of studies (5.25 years), graduation rate (41%) and drop-out rate (26%), (v) the employability after obtaining the Bachelor's degree is very high (>70%). In addition, Chemical engineering undergraduate and graduate students indicate their expectations are covered. In this paper, some consequences of the pandemic on students' performance (lower than before COVID-19) are analyzed, despite lectures tried to innovate in their classes and the university provided adequate tools for online teaching. • Chemical Engineering Bachelor's degree in Spain is in high demand. • Quality indicators show the current situation of chemical engineering degree. • Chemical Engineering students are satisfied with their degree and their employability. • The gender profile is adequate because woman students and lecturers are around 43%. • The pandemic affected students' performance despite university efforts.

This paper analyzes impoliteness-related language in response to a season's greeting posted by the Prime Ministers of Spain and the UK on December 2022 to wish Twitter users a Felices Fiestas/Merry Christmas. A corpus made up of the first 500 tweet events mentioning Sánchez and Johnson with the @ feature was analyzed through the combination of qualitative and quantitative tools and an impoliteness2 approach to compare the most commonly deployed impoliteness strategies in response to what is felt as an offense by respondents from the two cultures. Previous impoliteness taxonomies inform the analysis (Culpeper, 1996 , 2011). Findings reveal a preference for on-record strategies vs. off-record ones in both corpora. Whereas the English respondents oriented themselves towards attacking the negative face of the Prime Minister and that of other participants with sarcasm and implicated impoliteness, the Spanish group deployed impoliteness-related language to disparage the Prime Minister's positive face through insults and the rectification of his words. The hostile acts and explicit metalanguage about emotional states in the replies to the expressive speech act corroborate the perceived breach of some aspects of the moral order on the part of the Twitter users in the out-group, hence aiding the already observed polarization of political discussions. • Impoliteness is analyzed in replies to the season's greetings of Pedro Sánchez and Boris Johnson on Twitter. • Findings indicate that on-record impoliteness strategies are more frequent than off-record ones in both groups. • English respondents use negative-face attacking strategies, sarcasm, and implicated impoliteness in their replies. • Spanish respondents deploy insults and attacks on the positive public face of the Prime Minister as favored strategies. • Impoliteness-related discourse is multifunctional and aims to restore the moral order that is perceived as altered.

Tourism has become a very active ecosystem to deploy solutions based on Information and Communication Technologies. Indeed, it is now possible to analyse the mobility behaviour of tourists in great detail. However, current solutions aimed at anticipating tourist flows usually follow a limited approach based on the local (e.g., to predict the next landmark to visit) or regional (e.g., to predict the incoming number of tourists in a city) level. This paper states a novel approach to solve the problem of tourist inflow forecasting on a broader nationwide scale by defining it as an edge prediction task. To do so, we model the tourist mobility of a country as a graph which fuses heterogeneous tourism data obtained from multiple sources related to the country's mobility and infrastructure features. Then, as a major contribution, an ensemble of Graph Neural Networks are fed with the graph models to provide the final prediction. The proposed solution has been tested in Spain showing a F1 score higher than 0.7. • A mechanism to anticipate the flows of tourists in Spain is proposed. • The prediction is solved as an edge prediction between Spanish regions. • A Graph Neural Network has been used as underlying model. • The model is fed with touristic infrastructure data of Spain. • The human mobility is extracted from Call Detail Records and geo-tagged Twitter posts.

This paper studies the diverse actions, interventions and strategies initiated to address rising energy vulnerability among low-income households in the Barcelona region over the last decade. Drawing upon recent conceptual work around the politics of energy and in-depth fieldwork conducted over more than two years, we trace the different processes and sites through which the basic socio-material conditions of domestic access to energy have become politicised. We show how this involves a two-stage movement of deconfinement and reconfinement. In a context marked by austerity, an energy inefficient urban fabric and a centralised and oligopolistic energy system, energy vulnerability emerged from the domestic and private sphere to become framed as a public problem through parliamentary debate, social protest and local authority initiatives. Yet, energy access and vulnerability have also to some extent been recontained in the space of the household through the focus of recent local policy intervention on 'low cost' measurement, audit and equipment of domestic energy use. We argue that in reprivatizing what had become a public issue and thus redistributing responsibility for change to the household level, authorities and practitioners continue to ignore the systemic factors behind energy vulnerability situations and reproduce a status quo that benefits only energy utilities. The contribution of the paper is thus to show a politics of energy access that is increasingly constituted through entangled, fluid, blurred forms of relations between domestic and collective issues. This politics allows, for example, the need for systemic change to be framed as ostensibly a concern of households and to be met through fragmented, low-cost, metrological measures at that level.

• Border-crossing involves migrants' context-specific bodily performances. • Domestic employment requires and sustains gendered and racialized bodies. • Cross-border bodily circulation is based on the appropriateness of specific bodies. • Migrant bodies can be used as resources for improving living and working conditions. • Migrant marginalization abroad and (expected) privilege at home exist side by side. In migration scholarship, the migrant body has recently begun to gain recognition as a productive analytical scale for exploring politics of mobility: the highly differentiated ways in which migration is accessed and lived. However, a tendency to treat bodies as sites of gendered and racialized suffering can obscure migrant agency and differentiation as well as the ways in which migrant bodies can also be seen as sites of resistance and achievement. This paper aims to contribute to our understanding of the ways in which mobility politics shape divergent migrant trajectories by putting forward a translocal embodiment perspective. The paper argues that migrant bodies constitute key sites of struggle over mobility, and that looking at migrant embodied practice in translocal context can further unravel the differentiations that shape migrant trajectories across space and time. The paper's argument builds on theoretical notions of intersectionality, embodied cultural capital and translocality to enrich the discussion of mobility politics. Empirically, it draws on multi-sited ethnographic research with Nicaraguan families, focusing on female Nicaraguan migrants working in informal domestic employment in Spain, to explore how bodies and embodied practices matter throughout these migrants' trajectories. In particular, the paper intends to do justice to migrant agency by exploring how bodies that are often victimized can also be considered as stratified resources of translocal negotiation. The translocal embodiment perspective put forward in the paper shows that migrant bodies constitute a multi-faceted, non-erasable component of the unsettled yet situated mobility politics that shape divergent trajectories.

• Environmental attitudes are positively associated with the 3Rs of waste management. • Perceived effectiveness of one's own behavior is positively associated with the 3Rs. • These links are higher for recycling behaviors (separate glass, plastic and paper). • The 3Rs are also related to socio-demographics (gender, age and education level). • Women exhibit greater reducing and reusing (but not recycling) behaviors than men. This study explores how an individual's reported waste-related behaviors are affected by environmental attitudes and perceived effectiveness when facing a descriptive norm conflict (i.e., when the individual is the only person behaving pro-environmentally). The influence of the sociodemographic characteristics of gender, age, and education level is also examined. The reported behaviors relate to the 3Rs of waste management: reducing (buying minimally packaged products), reusing (buying products with reusable packaging), and recycling behaviors (separating glass, plastic, and paper). Based on a nationally representative sample of Spanish residents aged over 17 years (n = 2487), this study uses logistic regression analysis to assess the relationships between variables. The results show a positive relationship between environmental attitudes and the five reported waste-related behaviors. There is also a positive association between perceived effectiveness of one's own behavior (when nobody else acts pro-environmentally) and the five waste-related behaviors. Regarding sociodemographic characteristics, the results suggest that women, older individuals, and highly educated people engage more in these 3R behaviors. Building on these findings, policy and managerial implications are provided. For example, campaigns to promote environmental attitudes and the effectiveness of pro-environmental behaviors could focus on reducing and reusing behaviors, which entail the purchase of green products. Finally, some directions for future research are discussed. [ABSTRACT FROM AUTHOR]

The Basilica of St. Juan de Dios in Granada was built between 1734 and 1757; it is considered to be one of the great works of the Baroque architecture in Spain. This paper presents an architectural and constructive analysis of the dome over the transept; it was built according to the faux vault model divulged by Fray Lorenzo de San Nicolás (encamonada dome). We present an accurate geometric modeling of the dome and its constructive system, obtained from an on-site data collection campaign. This paper presents various hypotheses regarding the structural behavior of the filling in the extrados of the timbrel vault, according to its morphological characterization. The study of historical construction is presented through the application and contrast of different structural analysis methodologies: the experimental Guastavino's formulation, the analysis of stability by applying the slicing technique within the frame of Limit Analysis, and a new methodology based on funicular and projective geometry to determine efforts combinations in equilibrium. Finally, it presents conclusions about the combined use of them. [ABSTRACT FROM AUTHOR]

• Power is vested in institutional arrangements governing energy systems. • We track how institutional processes and local initiatives' trajectories co-emerge. • Energy initiatives' everyday negotiations with regulations are a site of politics. • Energy initiatives navigate regulatory constraints in experimental ways. • These experimental practices take shape in response to limits posed by regulations. Following critiques that scholarship on socio-technical transitions was overly normative and emptied of politics, a burgeoning stream of literature has begun offering understandings of transition that are more informed by politics. Whilst fruitful, there is a tendency in some of this work to constitute politics as the background or contextual frame in which socio-technical change unfolds, rather than as a process central to its emergence. Collaterally, relatively little attention has been given to how politics emerges in the everyday practices and struggles of energy initiatives. Engaging with recent work in urban studies, this paper explores how political processes unfold on the ground. We argue that one key site for this emergent politics is the institutional and regulatory arrangements that energy initiatives must navigate in carving out their activities. We do not address these simply as an externalised array of norms and procedures that variously impose upon and impede the efforts of energy initiatives. Instead, we explore how initiatives' trajectories are shaped by and entangled with the institutional and regulatory landscapes in which they operate. What we call politics emerges in and is exposed through initiatives' everyday efforts to negotiate and respond to regulatory strictures and opportunities. We explore the regulatory conditions that influence the everyday practices of three differently scaled energy initiatives in Scotland, Spain and Germany, each of which is variously involved in the generation, distribution and sale of energy. Our paper considers not only the ways that institutional arrangements generate obstacles for renewable energy innovation, but also how they may open up certain – albeit limited – possibilities for action, in some cases with larger ramifications for how the production and distribution of energy are governed. However, we note that where such possibilities arise, they are heavily determined by the terms set by existing institutional and regulatory frameworks, pointing to the limited scope for crafting new kinds of energy politics under current conditions.

• Validation of the photovoltaic estimation model SoL using data from real facilities. • The results for SoL are compared to other state-of-the-art PV estimators. • SoL presents more accurate results, despite being a simple and more efficient model. • A self-shading model is proposed for SoL as a new enhancement feature. • The self-shading feature is validated against real data and proved useful. The estimation of electrical power generation in photovoltaic (PV) grid-connected systems based on meteorological data is a nontrivial, highly useful task, for instance to achieve accurate energy assessment. Widely used PV generation simulators are PV Systems (PVsyst), System Advisor Model (SAM) and PVLib. These simulators are characterized by presenting numerous features and providing complete results, however the PV estimation model SoL is an example of a new approach to PV generation estimation. SoL is characterized by its simplicity and computational efficiency. The objective of this paper is validating the recently published SoL model using real data from two PV locations for several years and facilities and comparing the results with those of three other PV simulators, namely PVsyst (in Spain), SAM (in Denver) and PVLib (both). It has been found that SoL estimates power production accurately for both locations and its estimations are more precise than those given by PVsyst, SAM and PVLib. It proves to be more computationally efficient than PVsyst, it can work with higher resolutions than SAM and PVsyst and requires fewer inputs than PVLib, SAM or PVsyst. Finally, a self-shading model is proposed as an enhancement for the SoL model. The number of inputs required is minimal, and it is an approximate yet efficient model. The estimation when using the self-shading enhancement is even more accurate than the previous estimation for SoL in locations where self-shading is evident. SoL proves to be an appropriate model for power estimation, and its results are enhanced when using the self-shading model proposed in this paper. [ABSTRACT FROM AUTHOR]

Bird remains are rare on archaeological sites yet often crucial to address a multitude of questions, both cultural and biological. In this paper we argue that oribatid mites living on bird feathers, scales and nests may prove useful to infer not only bird presence but occasionally their breeding at a given site in the absence of their remains. Although oribatids are for all purposes stationary, a good number of species practice non-parasitic phoresis on birds that allows the mites to disperse over large distances. The specificity of the interrelationship, thus the quality of the bioindicator signal, is probably time-dependent, so that the longer the more specific the link between the vertebrate and the arthropod becomes. Oribatids are useful bioindicators because of the intensive sclerotization of their exoskeleton that insures their preservation in archaeological deposits. In this paper inferences about the bird assemblage retrieved at the Early Medieval site of Tabacalera (Gijón, Spain) are explored from the standpoint of the phoretic oribatids recovered in the deposits.

• Debates on the political ecology of populism has not reached the conservation field. • Yet a new populist conservation model is appearing in different locations in Spain. • Populist conservation builds on neoliberal and participatory conservation. • It permits the co-optation and privatization of conservation. • It can be resisted from an environmental justice rationale. The global surge of right-wing populism and its impact on environmental policies are attracting the attention of political ecologists. However, little of this debate has reached the nature conservation literature. In this paper, I explore the emergence of populist logics in conservation as a result of the entrenchment of neoliberalism after the 2008 economic crisis. On the one hand, neoliberalism has incited the roll-back of public institutions that hitherto monopolised the management of protected areas (PAs), as well as the roll-out of market-based and network-based forms of PA governance. At the same time, it has also had a significant impact on rural communities, imposing austerity policies that have caused a great deal of social and economic precarity and vulnerability, generating feelings of abandonment, dispossession and disenfranchisement. To illustrate how these two phenomena intersect and motivate the surge of right-wing populism in conservation, this paper dissects a number of parliamentary debates on a recent policy reform that seeks to decentralise the management of PAs in Asturias, a region in the north of Spain. These debates brought together stakeholders and members of several rural groups with different political orientations and views, including public administrators and policy-makers, farmers and livestock breeders, farmers' unions, landowners, tourism business owners, hunters and academics. I analyse how right-wing populist discourses framed this policy change, scapegoated the public management of conservation for all the problems suffered in rural areas, and co-opted popular demands of rural communities, reducing them to the economic interest of private landowners. I will also describe the various attempts made to negotiate a left-wing, progressive democratic alternative that hinges on the recognition of the social complexity of rural communities and the diversity of problems that affect them. The paper ends with a reflection on the lessons that the critical studies of conservation and public participation can learn from this negotiation. [ABSTRACT FROM AUTHOR]

This paper analyses the capacity credits (CCs) of renewable photovoltaic (PV), concentrated solar power (CSP) and wind technologies in the Spanish power system. This system has steadily increased the share of renewables, reaching a penetration level of over 30%. The predictions made by ENTSO-e suggest that this level will increase to 50% by 2030. Therefore, different scenarios are studied in this paper to investigate the evolution of renewable integration and assess the corresponding contributions to reliability. The assessment is performed using a sequential Monte Carlo (SMC) method considering the seasonality of renewable generation and the uncertainties related to renewable sources, failure issues and the maintenance of thermal-based units. The baseline for SMC is provided by historical annual time series of irradiance and wind power data from the Spanish system. In the solar case, these time series are transformed into power time series with models of CSP and PV generation. The former includes different thermal storage strategies. For wind generation, a moving block bootstrap (MBB) technique is used to generate new wind power time series. The CC is assessed based on the equivalent firm capacity (EFC) using standard reliability metrics, namely, the loss of load expectation (LOLE). The results highlight the low contribution of renewables to power system adequacy when the Spanish power system has a high share of renewable generation. In addition, the results are compared with those of similar studies. • The contribution of renewables to reliability in future scenarios is low. • Conventional generation has a key role to ensure reliability in future power systems. • Different storage strategies in CSP plants have a slight effect on reliability. • Hydro power in Spain contributes to increase the capacity credit of solar technologies. • Definitions of Capacity credit and Capacity value yield very different results.

• Occupational safety and health (OSH) technicians work in Spain as advisers in OSH matters. • This paper suggests an integration of OSH professional advice into business strategy. • Spanish firms seem to be driven by the market towards hiring prevention services. • A survey collected data on the role of OSH professionals in Spanish firms. • The survey results suggest improvements for OSH professional praxis in Spain. In the last few years, occupational safety and health (OSH) management systems in Spain have been implemented in firms by professional technicians who are gaining importance as advisers to guarantee minimum occupational accidents and to monitor occupational safety and health. This paper analyses the current situation of this profession in Spain, in terms of (1) individual criteria, referring, among other factors, to their training, qualifications, duties, and responsibilities; (2) collective criteria, referring to the situation of their professional group (prevention services entities, employers, market); and (3) environmental criteria, referring to their external perception as individual professionals and members of a professional group and their relationships with other agents. Along with the description of the Spanish situation we analyse the results of a survey carried out on Spanish OSH professionals (FSSOSHP) in which we collected primary data for each criteria category (individual, collective, environmental) in order to suggest improvements for their professional praxis. Finally, we discuss the results of our survey and emphasize the need to make improvements in individual, collective and environmental areas for OSH professionals and OSH management systems to progress in terms of further integration and increased efficacy of OSH activities in Spanish firms.
