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]

Abstract: Paper industry generates a considerable amount of wastes. Their composition mainly depends on the type of paper produced and the origin of cellulose fibres. Nowadays, in Spain, 40% of solid wastes generated by the paper and pulp industry are deposited directly in landfill, 25% are used in the agriculture, 13% in the ceramic industry and 7% in the concrete production. In the last years, thermal treatment methods like combustion, pyrolysis and gasification have been widely study as alternative techniques for the valorization of different organic waste materials. The main objective of the present work is to study the pyrolysis behaviour of different paper mill waste materials. For this reason, a wide characterization of eight paper mill waste materials from different origins was performed using SEM, FTIR, DRX and thermogravimetric techniques. Paper mill sludges from recycled paper, mainly wastes obtained from deinking process, showed high CaCO3 and clays contents. Compared with the elevated total organic matter content (TOM) of paper mill waste materials their low organic carbon content determined by Cr2O7 2− oxidation reveals the elevated chemical stability of organic matter, due to high content on cellulose fibres. Analysis of samples by SEM indicates that successive recycled processes of paper leads to paper mill waste materials with more degraded fibres. XRD analyses show as crystalline cellulose was present in reject and primary sludge from paper mills that produced paper from virgin wood. However, crystalline cellulose content significantly decreased in waste materials from recycled paper. Finally, thermogravimetric analysis indicates that presence or mineral matter and degradation of cellulose significantly influences their pyrolysis behaviour. In general, weight loss of paper mill waste materials started at lower temperatures than pure cellulose. In waste materials from recycled paper weight loss continues at temperatures highest than 500°C due to kaolinite dehydration and carbonates decomposition. [Copyright &y& Elsevier]

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.

Abstract: Purple nutsedge (Cyperus rotundus L.) is a serious weed capable of piercing polyethylene (PE) plastic mulch used in horticulture. A biodegradable plastic, PE and four different papers were tested for 2 years in fields highly-infested with C. rotundus in Zaragoza (Spain). All four papers were able to withstand all weed species. C. rotundus plants penetrated the biodegradable plastic mulch most, possibly because this material had least resistance to slow perforation. Differences in weed biomass between mulching materials were lower because of small size and weight of C. rotundus. Therefore all mulching treatments had a similar impact on weed biomass reduction 63 days after transplanting; biodegradable plastic had most biomass and papers the least, the differences being significant some years, only. Tomato yield was very similar for all mulching treatments and significantly higher than in the non-mulched plots. No effect of treatment was observed on fruit quality parameters. Commercial paper used as mulch without special additives can satisfactory control C. rotundus in processing tomato provided that climate is appropriate to maintain the paper dry during most of the time. Also the crop needs to cover the soil fast enough before the buried part of the mulch degrades allowing wind to lift and tear the mulch. [Copyright &y& Elsevier]

This article deals with a methodology for the design of routes for the “bin to bin” (BTB) collection of paper and cardboard waste (PCB) from small businesses, as well as with the new location and calculation of the number of containers needed in the streets for both commercial and non-commercial use due to the large amount of PCB deposited in them. This study was carried out in five shopping areas of the city of Leganés (Community of Madrid, Spain). One of the characteristics of the area is a high density of population and urban traffic. The tool used is the Geographical Information System (GIS-Arc-View). With it we can generate PCB points of high population density in commercial streets based on territorial analysis. We placed the special routes and the new container locations within a distance of 60m of these collection points (CPT). The system calculates and optimizes six routes according to different urban restrictions. Finally, we provided service to 59% of the shops, which generate almost 82% of the PCB waste, using 160min per day to collect 1027kg of high quality PCB. If we compare the system with the system in place previously, we can conclude that the “bin to bin” (BTB) system improves the quality of the PCB in the containers, avoiding overflow and reducing the percentage of rejected material.

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.

Abstract: In Spain, the paper industry recycles large amounts of waste paper in the new paper production process. Paper sludge thermal activation (calcination at 700 °C for 2 h) is an environment-friendly alternative source for metakaolinite (MK) to be used for the manufacture of blended cements or cement based materials. This paper could contribute to standardization of the use of new pozzolanic products in cement based materials and its use mixed with saturated lime dissolution. In this process are obtained zeolite, CSH gel, hydrotalcite-like compounds, hydrated aluminate tetracalcium and stratlingite. These materials are formed in different times of pozzolanic reaction.

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 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 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]

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.

• 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.

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.

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.

By applying a stochastic production frontier approach, this paper investigates regional inefficiencies of job creation in Spain over the period 2006–2012. This paper represents a first attempt to test whether a more flexible labour market as designed by the 2010 reform reduces regional inefficiencies. Results suggest that the 2010 reform appears to have improved on average the efficiency of the Spanish labour market even if regional differences persisted over time. The paper also investigates the importance of local democracy for the labour market finding that local democracy positively influences regional efficiency. [ABSTRACT FROM AUTHOR]

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.

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]

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.

• 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]

This paper studies individual preferences for place‐based attributes in the context of nature‐based domestic tourism trips. We examine the regional characteristics that explain tourist destination choice focusing on taste heterogeneity for distance and temperature. We examine the influence of a set of mean shifters in the marginal utilities for regional amenities, and how individuals are willing to trade distance in exchange for warmer (cooler) climates (i.e., marginal rates of substitution). Using a rich dataset of trips within Spain for nature‐based purposes, we find large heterogeneity in preferences for temperature differentials and distance, with trip purposes acting as moderators.

Abstract: The effectiveness of Science and Technology Parks (STPs) as instruments of innovation policy has generated thriving debate among academics, practitioners and policy makers. A gap in the existing literature on STPs is that research mostly does not consider STPs' heterogeneity. The present paper aims at filling this gap, analysing the influence of different STP characteristics on their tenants' performance. Using data on 849 firms and 25 STPs from the 2009 Community Innovation Survey for Spain and a survey of STP managers respectively and after controlling for a wide set of firms characteristics, we find that: (i) firms located in very new or longer established STPs show better innovative performance; (ii) the size of the STP and its management company positively affects the innovative performance of tenants while services provision has no effect on firms' achieving better results; and (iii) firms in less technologically developed regions benefit more from location in an STP. Theoretical, policy and managerial contributions of our research are discussed in the paper. [ABSTRACT FROM AUTHOR]

• 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]

• 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.

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.

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]

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]

The traditional shift‐share analysis and its existing spatial versions fail to detect the simple effects related to the underlying spillovers derived from the neighbourhood and regional contexts. This paper presents a formulation of the spatial shift‐share that incorporates novel effects and classifies the regions in a multi‐contextual framework (national, neighbourhood and regional). The use of different benchmarks is valuable since the performance of some regional sectors can be diagnosed with a national focus, while for others, it may be necessary to resort to neighbourhood and regional characteristics. Thus, the technique facilitates the formulation of strategies to improve the regional economic planning. [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.

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.

Abstract: This paper analyses the use of indicators for tracking the progress over time (2005–2010) of the municipal solid waste (MSW) management targets in the region of Cantabria (Northern Spain). The combined use of a set of material flow indicators together with estimations of carbon footprint (CF) is suggested. The MSW generation, the treatment of MSW (recycling, composting, incineration and landfilling), the recycling rates of glass, paper and cardboard and packaging wastes, and the landfill of bio-waste have been used as individual indicators. The main characteristics of different CF models applied to MSW management system are highlighted. Four CF models that allow indirect emissions accounting and that use a wide range of aggregated emission factors have been applied to the Cantabria MSW management system. According to the studied set of indicators based on material flows, some of the regional objectives for recycling rates have been achieved by 2010. Besides, the CF values have improved significantly in savings (−179,527tCO2e in 2005 to −310,566tCO2e in 2010) or in neat loads (74,443tCO2e in 2005 to 67,697tCO2e in 2010), depending on the CF model used. The decrease is due mainly to the implementation of the incineration plant at 2007 and the starts up of the municipal sewage sludge drying facilities. Further improvements on the MSW management indicators and additional reductions in GHGs emissions can be achieved through application of the specific actions on the Cantabria Regional Waste Plans by 2014. The analysed material flow indicators together with the CF data obtained in the present work would be useful in the regional planning decisions on the MSW management issue. [Copyright &y& Elsevier]

Abstract: This work analyses the separate collection systems used in Spanish towns with between 5000 and 50,000 inhabitants. The study looks at the systems and their efficiency by means of the indicators fractioning rate, quality in container rate and separation rate. The results obtained are compared with those from a similar study conducted earlier that was applied to towns and cities with populations over 50,000. It can be concluded that the most widely implemented system in Spain involves the collection of mixed waste from kerbside bins and picking up paper/cardboard, glass and lightweight packaging from drop-off points. Findings show that the best system is the one that collects mixed waste, organic material and multiproduct waste door-to-door, and glass from drop-off points. The indicator separation rate made it possible to establish beta regression models to analyse the influence of the following logistic variables: inhabitants per point (people/pt), time (years) and frequency of collection (freq). From these models it can be seen that people/pt has a negative effect on all the fractions, while freq and years have a positive effect in the case of paper. [Copyright &y& Elsevier]

Abstract: In this study 10 commercial top selling cigarette brands in Spain have been machine smoked and the mainstream smoke has been analyzed. Multifunctional analysis has been satisfactorily employed to correlate the effect of the main design features of the cigarettes including amount of tobacco, filter size or paper weight with the amount of smoked tobacco and with the ratio CO2/CO. The composition of the vapor phase and that of the particulate matter have been analyzed. The particulate matter retained in the filter of the cigarettes has also been analyzed showing a distinct behavior of the compounds condensed in the cigarette filters and in the traps, related to their retention time. A general trend for the relative yield of some compounds in the different brands have been identified and confirmed by multifunctional analysis. Nevertheless, there are some noticeable compounds that behave differently in the different brands. [Copyright &y& Elsevier]

Abstract: The main aim of this work is to progress in the study of desertification processes in Mediterranean regions in the framework of DESERTNET project by means of the execution of pilot studies and development of evaluation models. This paper shows the results of an investigation on the degradation processes of soils carried out in the Murcia Region (SE, Spain). Specifically, salinization problems in Murcia Region were evaluated by means of two chemical degradation indicators, salinization state and salinization rate. We define chemical degradation indicator as the representative value of an observed chemical phenomenon in soil which produce its degradation. Chemical degradation indicators were calculated in order to simplify the interpretation of all the complex processes involved in environmental monitoring. The results obtained showed that in some areas an increase in salinization processes is taking place. On the other hand, there are only a few points with high a risk of salinization, obtaining similar results in the two periods of time studied. [Copyright &y& Elsevier]

Abstract: Pulp industry plays an important role in the structure of European economy and society. Paper pulp manufacture, the industrial utilization of plant biomass, is increasing every year. In Spain, Eucalyptus is the dominant raw material and the Kraft cooking and total chlorine free (TCF) bleaching processes lead the procedures of Eucalyptus paper pulp production. This paper aims to identify and quantify the environmental impacts associated to Eucalyptus TCF pulp manufacture by using Life Cycle Assessment (LCA) as an analytical tool. The system has been defined using a cradle-to-gate perspective, that is to say from forest activities to the exit gate of the pulp mill. The production of chemicals consumed in the cooking and bleaching stages as well as the on-site energy production system is the elements that contribute the most to all impact categories analyzed (more than 50% of total contributions), except for the eutrophication potential where forest activities and waste treatment play an important roles (about 52% of total). Specific actions associated to the recovery boiler, lime kiln and digestion stage could considerably reduce the environmental impact and improve the environmental performance of the Spanish paper pulp industry.

The relationship between labour force participation and the business cycle is a common topic in economic literature. However, few studies have examined if the cyclical sensitivity of labour force participation is influenced by social effects. In this paper, we construct a theoretical model defining a relatively new hypothesis, the bandwagon worker effect (BWE). We use spatial econometrics techniques to test the existence of the BWE in the local labour markets in Spain. Our results reveal a positive spatial dependence in the cyclical sensitivity of labour force participation that decreases as we fix a laxer neighbourhood criterion, which verifies the existence of the BWE.

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.
