This comment provides a critical analysis of Van Beukering and Bouman’s [World Development 29 (2001) 1717] article on global paper recycling and trade. We first question their notion that developing countries specialize in waste paper utilization and developed countries in recovery activities primarily because of different patterns of waste paper trade. An increased focus on relative waste paper availability, we argue, provides us with a better understanding of global paper recycling. We also criticize some of the implicit assumptions made in their regression analysis of waste paper utilization rates. An alternative regression model is therefore derived and estimated. In contrast to the approach used by Van Beukering and Bouman our analysis (a) is consistent with basic microeconomic theory; (b) distinguishes clearly between short- and long-run impacts; and (c) produces results that support our initial conjecture that waste paper availability is the most important determinant of waste paper use.

Abstract: Total hip-joint arthroplasty is performed in increasing numbers where it translates to about 0.16–0.2% of population per year in industrial countries. In most cases, an implant is a metallic component articulating with a metal, ceramic or poly-ethylene liner as seen in the case of hip, knee and spine. The metal implants release ions in vivo. Therefore, there is a need to study metallic implants and ions released as a result. Toxic concentrations of ions can lead to many adverse physiological effects, including cytotoxicity, genotoxicity, carcinogenicity, and metal sensitivity. There is a need to map ion concentrations establishing boundaries between normal and toxic levels; which however, does not exist. Reference levels of ion concentrations in body fluids and tissues determined by many studies are compiled, reviewed, and presented in this paper. The concentrations of ions released from different alloys, including cobalt, chromium, nickel, molybdenum titanium, aluminum, and vanadium, are presented in this paper. This paper reviews the literature pertaining to clinical data on metal ion concentrations in patients with metal joint prostheses, and laboratory data on the physiological effects of the metals.

Mobility as a service (MaaS) is an emerging framework that integrates multiple transport services into a single and intuitive platform. This paper contrasts the urban passenger transport markets in developed versus developing economies to understand the challenges of integrating mobility services using the MaaS framework, with a focus on decarbonization and sustainability as societal goals. In addition, we conducted a Life Cycle Assessment of carbon emissions and energy requirements of travel alternatives in the city of Santiago, Chile, to shed light on the effects of multimodality as an environmental tool. A summary of findings follows. Data sharing and open data are new in developing countries, and thus more investment in data infrastructure is required so that MaaS can leverage digital technology and network optimization. If the scalability of MaaS is an open question in developed countries, it is more so in developing countries, owning to institutional and financial constraints that are present in the latter. The lack of public subsidies to support formal public transport is a key limitation for the implementation of MaaS schemes and multimodal frameworks in the developing world. Regarding formality, in countries with an informal public transport sector, a potential implementation of MaaS will be spatially constrained to those locations where public transport operates formally and frequently (BRT and rail lines), limiting its spatial coverage and posing social equity issues. In countries with scarce or no public funds available for the transport sector, MaaS could be used as a catalyst for a broad environmental and equity-seeking transport pricing reform which requires a direct involvement of public sector in both regulation and financial backing. We conclude that the formalization and general improvement of the public transport sector, the regulation of shared-mobility platforms including the formalization of the work of drivers, and the setting of proper pricing and subsidization instruments in the direction of internalizing the social costs of motorized traffic, are all prerequisites for any MaaS system that aims to improve economic efficiency, social equity, and sustainability. • Assess MaaS as a framework for decarbonization in developing world. • Discuss governance and equity issues in implementing MaaS. • Identify carbon policy for different cities to achieve sustainability. • Conduct a life cycle assessment to inform carbon strategies. • Scalability is a key challenge in both developing and developed worlds.

Paper-based analysis has captivated scientists' attention in the field of analytical chemistry and related areas for the last two decades. Arguably no other area of modern chemical analysis is so broad and diverse in its approaches spanning from simple 'low-tech' low-cost paper-based analytical devices (PADs) requiring no or simple instrumentation, to sophisticated PADs and microfluidic paper-based analytical devices (μPADs) featuring elements of modern material science and nanomaterials affording high selectivity and sensitivity. Correspondingly diverse is the applicability, covering resource-limited scenarios on the one hand and most advanced approaches on the other. Herein we offer a view reflecting this diversity in the approaches and types of devices. The core idea of this article rests in dividing μPADs according to their type into two groups: A) instrumentation-free μPADs for resource-limited scenarios or developing countries and B) instrumentation-based μPADs as futuristic POC devices for e-diagnostics mainly aimed at developed countries. Each of those two groups is presented and discussed with the view of the main requirements in the given area, the most common targets, sample types and suitable detection approaches either implementing high-tech elements or low-tech low-cost approaches. Finally, a socioeconomic perspective is offered in discussing the fabrication and operational costs of μPADs, and, future perspectives are offered. [Display omitted] • Microfluidic paper-based devices (μPADs) constitute a very broad and diverse area. • Varied approaches for contrasting needs and capabilities of developed and developing countries. • Low-tech low-cost approaches requiring no or simple instrumentation. • Sophisticated μPADs feature elements of modern material science and nanomaterials.

Carbon footprints (CFs) are the measure of extent of green house gases (GHGs) emitted from any organization or activity. Reporting of extent of CFs in terms of CO 2 e from educational campus may be considered as a first step towards sustainable educational practices. The present study employs a bottom up approach where CFs due to consumption of resources from each academic department is evaluated separately and net is obtained by adding contributions from individual departments. This method has the advantage of avoiding the potential overlaps in the calculation. Hence this approach to calculate carbon footprints can lead to their precise CF evaluation. In order to justify above hypothesis, CF evaluation was carried out at Shikshana Prasarak Mandali's Sir Parashurambhau College, Pune for three consecutive years starting from 2015 to 2016. The average carbon footprints over the study period were 3630.57 ± 296.79 tones CO 2 e per year with per capita emission of 0.81 ± 0.06 tones CO 2 e. The emission density determined from the average value was found to be 0.0361 ± 0.0029 tCO 2 e m−2 of the campus. It was observed that emission sources classified as scope-1, scope-2 and scope-3 contribute 28%, 48% and 25% respectively to total emission. Out of all the emission sources identified, apart from human contribution through respiration, electricity (35%), biodegradable and non-biodegradable waste, stationary paper, 7%, use of chemicals in the laboratories (5%), paper for official purpose (12%), LPG (3%) and transport (27%) were main contributors. As this is a multi faculty college, science faculty contributes almost 62%, commerce 9% and arts 11% of the total emission. • Present paper highlights carbon footprints from an Indian HEI using bottom up approach. • A questionnaire based survey was used to arrive at departmental and net footprints. • Carbon footprints of HEI in India are much less as compared to developed countries. • The carbon footprints of Indian HEIs are expected to grow at 5–6%.

In the context of a secular decline in internal migration across more developed nations, this paper examines the degree of counterurbanisation in New South Wales – Australia's most populous state – for 2016-21, a period that included the COVID-19 pandemic. Using a nuanced demarcation of 'metropolitan' and 'non-metropolitan', the paper investigates how genuinely counter-urban and pro-rural these movements are. The paper also explores the role of rural amenity as a 'pull' factor on city populations, using the most influential elements of the rural environment that best predict in-, out-migration and net-migration flows as separate measures rather than combine them into an index of composite variables. The results suggest that counterurbanisation exists as a particular migration current in NSW, though the spatial patterning of in- and net migration rates suggests that exurbanisation and displaced urbanisation more accurately describe and explain the vast majority of moves. Relatively high in- and net migration rates recorded in the most remote local government areas also suggest an element of anti-urbanisation, perhaps in response to the COVID-19 public health measures. Spatial regression modelling of selected amenity indicators against in-, out- and net migration produced high coefficients (Spearman's rho) for the in- and out-migration models, while the net migration model registered coefficients about half the size of the other two models. Two indicators – median slope and tourism employment – were strong and statistically significant influences over the in- and net migration models, and in the direction hypothesised. These results suggest that counterurbanisation is substantially influenced by the presence of landscapes of varied relief and with some tourism attraction potential. • The spatial patterning of in- and net migration rates between the New South Wales metro region and non-metro regions suggest that exurbanisation and displaced urbanisation more accurately explain the vast majority of moves. • Relatively high in- and net migration rates recorded in the most remote local government areas of NSW also suggest an element of anti-urbanisation, perhaps in response to the COVID-19 public health measures. • Two indicators – median slope and tourism employment – had statistically significant influences over the in- and net migration models in spatial regression modelling.

Point-of-care (POC) diagnostics play an important role in delivering healthcare, particularly for clinical management and disease surveillance in both developed and developing countries. Currently, the majority of POC diagnostics utilize paper substrates owing to affordability, disposability, and mass production capability. Recently, flexible polymer substrates have been investigated due to their enhanced physicochemical properties, potential to be integrated into wearable devices with wireless communications for personalized health monitoring, and ability to be customized for POC diagnostics. Here, we focus on the latest advances in developing flexible substrate-based diagnostic devices, including paper and polymers, and their clinical applications. [ABSTRACT FROM AUTHOR]

This paper explores the social implications of servitization and unveils the connections between servitization and social innovation. To substantiate these claims, the research elucidates three core concepts of social innovation, namely processes, instruments, and outcomes. The processual view of social innovation examines how societal changes unfold; the instrumental view focuses on tools and mechanisms driving these changes; and last the outcomes view analyses the resultant benefits. The paper reviews systematically the literature on the social impacts of servitization and, based on the mentioned views uses the literature findings to inductively develop three propositions and demonstrate that servitization can represent a form of social innovation, thus capable of profoundly reshaping industrial societies and contributing to progress and people's well-being. In sum, the paper shows the social implications and benefits related to servitization of manufacturing firms and suggests the research priorities in this domain for servitization scholars. • The paper systematically reviews the literature to identify the social implications of servitization. • The paper uses three views to unveil the connections between servitization and social innovation. • The paper theorizes that servitization is a form of social innovation that contributes to progress and people's well-being. • The paper suggests research priorities in this area.

Financial development and demographic changes have an important impact on the non-hydro renewable energy industry, and this impact is significantly different in countries at different stages of development. This paper studies 10 developed countries and 10 developing countries using annual data from 1990 to 2018. Through the panel cointegration estimation method, the paper evaluates the impact of financial development and demographic changes on the non-hydro renewable energy industry. The empirical results show that the stock market and bank intermediary have a significant role in promoting the growth of the non-hydro renewable energy industry in developing and developed countries. The bond market has a significant positive impact on the growth of the non-hydro renewable energy industry in developed countries only. Foreign direct investment in developing countries significantly promotes the growth of the non-hydro renewable energy industry, while in developed countries it has a negative impact. Population aging has a significant inhibitory effect on the growth of the non-hydro renewable energy industry in developing and developed countries. [ABSTRACT FROM AUTHOR]

• Identification of important indicators for process safety. • A comparative study of process safety indicators in developing and developed countries. • Measuring the relative importance of the indicators using the Fuzzy Best Worst Method. Introduction: The importance of safety in high-risk industries such as oil and gas facilities has been reported previously. Process safety performance indicators can provide insight into improving the safety of process industries. This paper aims to rank the process safety indicators (metrics) by Fuzzy Best-Worst Method (FBWM) using the data gathered through a survey. Method: The study uses a structured approach considering the UK Health and Safety Executive (HSE), the Center for Chemical Process Safety (CCPS), and the IOGP (International Association of Oil and Gas Producers) recommendations and guidelines to generate an aggregate set of indicators. It calculates the level of importance of each indicator based on the opinions of experts from Iran and some Western countries. Results: The findings of the study demonstrate that some lagging indicators such as the number of times processes do not proceed as planned due to insufficient staff competence and the number of unexpected disruptions of the process due to failure in instrumentation and alarms are important in process industries in both Iran and Western countries. Western experts identified process safety incident severity rate as an important lagging indicator, whereas Iranian experts considered this as relatively unimportant. In addition, leading indicators such as sufficient process safety training and competency, the desired function of instrumentation and alarms, and proper management of fatigue risk play an important role in enhancing the safety performance of process industries. Experts in Iran viewed permit to work as an important leading indicator, while experts in the West focused on fatigue risk management. Practical Applications: The methodology used in the current study gives a good view to managers and safety professionals in regard to the most important indicators of process safety and allows them to focus more on important process safety indicators.

Megatrends such as urbanization, digitalization, and decarbonization have created the necessity for new and creative approaches to the urban transportation system. As a solution to the problems of the increasingly digitalized urban transportation environment, "Mobility-as-a-Service" (MaaS) was proposed as a new sustainable transportation concept in Helsinki in 2014. With the use of the MaaS concept, residents of a large emerging metropolis, such as Istanbul, Turkey, can be offered a fast, efficient, environment-friendly, and inexpensive way of travel. However, despite the significant benefits of MaaS, there are several factors that can hinder the adoption of MaaS. This paper aims to analyze these barriers and their contextual relationships with each other using Total Interpretive Structural Modeling (TISM) and Matrix-based-Multiplication-Applied-to-a-Classification (MICMAC) methods. The case study has been conducted on an expert group to explore which significant barriers might be encountered during the adoption of a MaaS system in Istanbul. This study also addresses how these barriers should be overcome, and the MaaS concept should be adopted in Istanbul. The results showed that the most significant barrier to adopting the MaaS concept in Istanbul are Laws, Regulations, and Guidelines that primarily include the legal nature of this mobility service. The least important barriers are found to be Customer Acceptance and Labor Shortage. Therefore, the case study results provided a unique perspective for emerging countries in terms of barriers to successful MaaS implementations and revealed significant differences from the developed countries. • This study is the first study to investigate the significant barriers to the successful adoption of MaaS for developing country context. • Istanbul is selected as a large emerging metropolis case. Eight possible barriers are identified with an extensive systematic literature review. • Total Interpretive Structural Modeling is used to identify and interpret these barriers, and MICMAC is used to classify the m by an expert group. • Laws, Regulations, and Guidelines is found as the most significant barrier in adopting the MaaS concept in Istanbul. • The least important barriers are found to be Customer Acceptance and Labor Shortage.

• A systematic review is done on the effects of safety climate on safety performance. • Safety climate is predominantly used as a predictor. • Safety-related behavior is the most common definition of safety performance. • Methods used to link safety climate and safety performance is methodologically biased. • Literature on safety climate is dominated by studies in developed countries. Introduction: Since its inception more than four decades ago, research on safety climate has been conducted in many industries. Subsequently, a plethora of systematic literature reviews on safety climate in various work environments has focused on research trends and measurement scales. Yet, despite these reviews, the overall picture of how safety climate influences performance is still not well understood. The current study reviews existing literature on safety climate, specifically how it affects safety performance. Method: Literature searches were conducted using EBSCOhost and Web of Science databases in March 2021. We included English-language, peer-reviewed studies that reported the results of research done on safety climate and safety performance. We extracted data (contextual, theoretical, methodological and definition of safety performance) from these studies and were deductively analyzed and categorized into common themes. Results: One hundred and sixty-two safety climate studies were identified. We found that studies on safety climate–performance were conducted in 16 types of industries while 23 different theories explained the safety climate–performance relationship. The quantity and quality of variables and methods used varied considerably across the surveys. Safety climate is predominantly used as a predictor while safety-related behavior is the most common definition of safety performance among the articles we reviewed. Few papers from the current review were methodologically strong, suggesting that current evidence on the link between safety climate and safety performance still suffers from common method bias. Conclusions: Although literature has provided evidence for the positive effect on safety performance via a strong safety climate, strong and convincing methods are still lacking and the causality of an improved safety climate still needs to be demonstrated. Practical applications: The findings of the current review offer a better understanding of how employers can improve safety climate in the workplace in various settings. [ABSTRACT FROM AUTHOR]

• We examine whether there was a real improvement in patent quality or productivity with the patent surge in China. • We focus on large and medium-size enterprises (LMEs) and construct a unique data set that links firm-level production data (from the ASIEC database) with data on patent quality. The matched firm-level data spans from 1998 to 2013. • Using fixed effects regressions, we find that the initiation and intensity of patenting activities (quality-adjusted or not) are positively associated with an LME's productivity. These results are robust to productivity measured in either output productivity, sales productivity, or TFP. • We find that firms' conscious R&D efforts had positive influences on the overall quality of patents in China. However, we also discover that China's utilization of R&D investments was not that efficient, the association between R&D and patent quality had become weaker in more recent years, and the growth of patenting was still relatively unbalanced. This paper examines whether there was a real improvement in patent quality or productivity with the patent surge in China. Based on the novel database we compiled, we demonstrate that accumulated patent stock measured using quality metrics was positively associated with the productivity of large and medium-size enterprises (LMEs). We also find that R&D investments by LMEs led to increases in patent quality. However, the estimated R&D-patenting elasticities in China are found to be lower than those estimated in developed countries. We offer some explanations and discuss their implications for policy considerations. [ABSTRACT FROM AUTHOR]

In today's globalized economy and highly interconnected media landscape, the impact of country-of-origin (COO) effects on crisis spillovers has attracted growing interest. However, the majority of the relevant studies are limited to case studies. A clear understanding of the relationship between COO effects and crisis spillovers has yet to be established. To address this gap, a meta-analysis of 24 causal pairs from 9 papers (n = 5746, combined n = 10942) was performed. The results indicate that COO effects can somewhat limit crisis spillovers. Specifically, the COO effect has a medium degree of mitigating effect on morality (r = 0.403) and competence crises (r = 0.240). When the COO is a developed country (r = 0.345), the COO effect can effectively mitigate crisis spillovers to a medium extent, while when the COO is a developing country (r = 0.180), the COO effect is small. Using organizational impressions (r = 0.357) rather than purchase intentions (r = 0.157) as a measurement instrument makes it easier to observe the dampening effect of COO on crisis spillovers. These findings enrich the theoretical framework of public relations and crisis management and provide strategies for business organizations to cope with spillovers. • Morality and competence crises moderately modulate the relationship between country-of-origin effects and crisis spillovers. • Developed countries' country-of-origin effects more significantly dampen crisis spillovers than in developing countries. • Differences in crisis measurement tools affect the results of crisis assessment.

[Display omitted] • A multi-criteria analysis is developed to assess barriers to electric bus adoption. • 28 barriers are identified and a survey is applied to 48 experts from 31 countries. • The weight of each barrier is determined based on a fuzzy best-worst method. • A comparison of barrier weights is made between developed and developing countries. • Economic barriers are the most challenging aspects worldwide. Public transportation agencies have prioritized transitioning to battery electric buses to enhance sustainable urban mobility. However, this transition faces barriers of various dimensions, including technological, economic, social, management, and environmental aspects. This paper develops a multi-criteria decision-making approach to identify and rank barriers to battery electric bus adoption. First, an evidence-based list of 28 barriers is introduced through an extensive literature review and expert interviews. Then, by designing a fuzzy best-worst method, a structured approach is developed to quantify the weights of these barriers and delineate their relative challenging levels. Besides, a cross-country comparison of barrier weights is conducted between developed and developing countries, utilizing data collected from a diverse panel of experts across 31 countries worldwide. The results highlight the economic aspect (weight: 0.291) as the most challenging barrier worldwide, followed by the technological aspect in developed countries (weight: 0.277) and the management aspect in developing countries (weight: 0.252). The most significant difference in barrier weights between developed and developing countries is observed in management. Range limitation (weight: 0.051), high electricity tariffs (weight: 0.050), and challenges in selecting suitable charging technology (weight: 0.037) are specific barriers exhibiting larger weights in developed countries, while lack of financing options (weight: 0.051), lack of plans to remove diesel bus stock (weight: 0.038), lack of expertise (weight: 0.034), and existence of an informal transit sector (weight: 0.024) are specific barriers receiving larger weights in developing countries. The findings are discussed to offer strategic recommendations for tackling high-priority barriers and accelerating battery electric bus adoption. [ABSTRACT FROM AUTHOR]

The evolution of resource requirements in developed countries after the 2008 crisis seemed to indicate that there is a process of dematerialization. This paper analyses dematerialization in a group of developed countries and the effects of the economic cycle on resource use. The aim is to determine whether dematerialization can be linked to the effects of the economic crisis or, on the contrary, is independent of the economic context. To do this, a descriptive part is proposed in which the existence of dematerialization over the last 50 years is analysed. Subsequently, a model is estimated in which the effect of recessionary, low-growth and normal growth periods on the consumption of material resources is contrasted. The raw material input is used as an indicator of the use of material resources, which makes it possible to link each country to all the resources it requires for the normal functioning of its economy, regardless of where they are consumed. Among the main results, it can be noted that reductions in resource consumption occur in periods of recession and low growth, while for growth above 2% there is no dematerialization.

• We test for Granger causality in mean and quantiles between wage share and capacity utilization in developed countries. • We employ confidence intervals generated by bootstrap and the Wald test for joint significance. • Capacity utilization positively Granger causes the wage share in eight countries at the center, lower and upper tails. • The positive Granger causal effect of capacity utilization is strong, heterogeneous, and larger for extreme quantiles. • The wage share negatively Granger causes capacity utilization in all quantiles in Spain and above the median in Italy. This paper tests for Granger causality in quantiles between the wage share and capacity utilization in twelve developed countries using annual data ranging from 1960 to 2019. Instead of focusing only on the conditional mean, we test for Granger causality in the entire conditional distribution of the variables of interest. This method detects Granger causal dynamic relations in both the mean and the whole conditional distribution using bootstrap confidence intervals and the Wald test. Our results indicate that capacity utilization positively affects the wage share in eight out of the twelve sample countries. This Granger causal effect is strong and heterogeneous across quantiles, being larger for more extreme quantiles. Capacity utilization positively Granger causes the wage share in all conditional quantiles in the U.S., Sweden, and Italy. Meanwhile, the wage share negatively Granger causes capacity utilization in all conditional quantiles in Spain and in some quantiles above the median in Italy. [ABSTRACT FROM AUTHOR]

Impacts of coronavirus disease 2019 (COVID-19) on the transport sector and the corresponding policy measures are becoming widely investigated. Considering the various uncertainties and unknowns about this virus and its impacts (especially long-term impacts), it is critical to understand opinions and suggestions from experts within the transport sector and related planning fields. To date, however, there is no study that fills this gap in a comprehensive way. This paper is an executive summary of the findings of the WCTRS COVID-19 Taskforce expert survey conducted worldwide between the end of April and late May 2020, obtaining 284 valid answers. The experts include those in the field of transport and other relevant disciplines, keeping good balances between geographic regions, types of workplaces, and working durations. Based on extensive analyses of the survey results, this paper first reveals the realities of lockdowns, restrictions of out-of-home activities and other physical distancing requirements, as well as modal shifts. Experts' agreements and disagreements to the structural questions about changes in lifestyles and society are then discussed. Analysis results revealed that our human society was not well prepared for the current pandemic, reaffirming the importance of risk communication. Geographical differences of modal shifts are further identified, especially related to active transport and car dependence. Improved sustainability and resilience are expected in the future but should be supported by effective behavioral intervention measures. Finally, policy implications of the findings are discussed, together with important future research issues. • Findings are derived from a worldwide expert survey implemented in April–May 2020. • Guidelines and contingency plans were reported by only about 30% of experts. • Remarkable modal shifts away from public transport usage were reported. • Developing countries were equally active in taking measures as developed countries. • Various long-term changes in lifestyles and society were revealed.

Hypersonic vehicles have been paid more and more attention by various countries, and many developed countries have set off a competition of hypersonic technology. Under this background, this paper creatively applies the reconstruction method based on three vanishing points to the reconstruction of complex aircraft for the first time. The shape of aircraft is restored by photos from different angles, which provides a good help for preliminarily understanding and mastering the information of international mainstream advanced aircraft. In this paper, the feasibility of the whole method is verified by the classical X-37B model, and its three-dimensional structure model can be obtained relatively accurately. In terms of aerodynamic performance evaluation, the panel method is adopted to evaluate the aerodynamic performance on the basis of verifying the reliability of the engineering method. And the results show that the lift-to-drag ratio reaches the maximum of 1.22 at the angle of attack of 25°. This is quite similar to the CFD calculation of class X-37B model in other literatures. The accuracy of the model makes up for the error of the engineering estimation method to a certain extent. In view of the inaccuracy of the wing reconstruction, the genetic algorithm is used to optimize its aerodynamic performances. The lift-to-drag ratio of the wing is increased by 26.3% at 25°, which leads to an increase of 4.35% in the optimal angle of attack lift-to-drag ratio of the whole model. At last, the modularization programming approach is adopted in the optimization process, ensuring the generality of this method, and the whole method will have a broad application prospect. • A reusable vehicle was reconstructed by the developed reverse engineering approach. • The aerodynamic performance of the reusable vehicle was optimized. • When the angle of attack is 25°, the lift-to-drag ratio reaches the maximum value of 1.22. • The overall lift-to-drag ratio of the model is with an increase of 4.35%.

While the aviation sector has long been referenced as contributing to the causes of climate change, the need for aviation to adapt to the consequences of climate change has not been as well researched or considered. The paper is a systematic quantitative literature review on climate change and aviation, which aims to explicate significant issues affecting aviation in a changing climate and to identify the aviation industry responses on climate change and adaptation. There are 46 references involved in the detailed assessment, selected according to variables such as methodology, paper outcomes and industry stakeholder. This emergent aviation and climate change adaptation literature could be broadened to cover more disciplines and approaches, an increased range of aviation stakeholders and go further beyond the larger airport case studies in developed countries. Further practical and policy developments are needed, particularly surrounding adaptation planning in aviation and the social justice implications of associated policies. [ABSTRACT FROM AUTHOR]

The dramatic increase in textile waste and the ineffective disposal of textiles as emerging global issues are driving researchers to study new ways of thinking and designing textile waste policies with the aim of conserving resources and reducing the environmental impact of textile waste. However, there is limited research that systematically and comprehensively examines the development processes of policies that govern textile waste management. It is important to identify the underlying issues and improve textile waste management systems. This paper fills this gap by presenting a comprehensive study of the development and characteristics of policies related to textile waste in China. All the major textile waste policies issued between 1991 and 2017 at the central-government level have been examined to ensure accuracy and reliability. To achieve the descriptive objective of the study, content analysis was employed, and the following conclusions were derived: (1) The number of policies has gradually increased since more stringent textile waste management was introduced in 2001, and although the Chinese government has continuously reinforced its supervision from 2010 onwards, stringency remains low; (2) most policies regulate the recycling level of the waste hierarchy, as in open-loop recycling, and only a couple of polices regulate higher levels; and (3) the highly imbalanced structure of policy instrument types has been changing, and the variety of policy instruments has peaked in recent years. This paper contributes a general and important reference relating to textile waste policies for governments and businesses in other industrialized nations. [ABSTRACT FROM AUTHOR]

As global concern shifts from developed countries—many of which have made significant strides towards carbon neutrality—to developing nations, an urgent need arises: how can the latter effectively borrow and adapt strategies that have proven successful in the former? This review thoroughly explores the successes and challenges encountered by developed countries in terms of emission accounting, mitigation strategies, and transitioning to renewable energy sources. We then explore how these strategies can be feasibly integrated into the economic, social, and political contexts of developing countries. Furthermore, this paper highlights the importance of customizing these strategies to the unique challenges and opportunities of developing nations, rather than simply replicating efforts. Through a comparative analysis, we present a roadmap to carbon neutrality that acknowledges the distinct contexts of these developing countries while drawing inspiration from global successes. This approach underscores the necessity of a collaborative, global effort in addressing climate change, recognizing the interconnectedness of all nations in this endeavor. It also sets the stage for future research and policy development that are both locally informed and globally conscious. [Display omitted] • Comprehensive analysis of emission accounting successes in developed countries. • Exploration of the unique challenges and opportunities in developing nations. • Emphasis on tailoring, not duplicating, carbon neutrality strategies. • Proposing a cohesive, global approach grounded in local context and solutions.

There are a wide range of interventions that are designed to influence employer behaviour with respect to the employment of people with disabilities. This study presents the results of a systematic review looking at employer-focused interventions to improve disability employment, focusing on interventions or policies taking placing in high-income countries as per the OECD. This systematic review focuses on a broad range of potential employment-related outcomes, including the employment rate, time to return to work and length of sickness absence. The results of 71 papers that evaluate the effectiveness of a range of interventions were synthesised into a narrative review. Interventions are grouped into six broad categories: anti-discrimination legislation, quota systems, part-time sick leave, graded return to work and wage subsidy schemes. Anti-discrimination legislation is not effective at improving the employment prospects of people with disabilities. There is mixed evidence with respect to quota systems and wage subsidy schemes. However, the availability of part time sick leave or graded return to work are both consistently associated with improved work participation for people with disabilities. • A range of policies aim to influence employers to employ people with disabilities. • Anti-discrimination legislation has no effect on disability employment. • There is mixed evidence regarding quota systems and wage subsidy schemes. • Part-time sick leave and graded return to work associated with improved outcomes.

Green finance, clean technology innovation (CTI), and environmental tax are all eco-friendly measures for diminishing environmental degradation. Few studies have examined how these variables work together to realize the object of green growth (GG). Therefore, this research aims to examine the role of the above factors in achieving GG by using 28 developed countries from 1995 to 2019. These countries have passed over a time of fast progress at the expense of heavy pollution and hence have moved their emphasis to GG. This paper starts with the construction of the GG index based on entropy-weighted TOPSIS, followed by pooled OLS, fixed effect, random effect, the two-step least-square estimator (2SLS), and the System GMM models for hypothesis testing. From the findings, it is obsense of that: (1) Green finance positively affects GG; the higher the levels of GG, the greater the enhancement of green finance on GG. (2) CTI favorably mediates the impact of green finance on GG, and the mediating effect accounts for 14.06% of the overall effect. (3) Environmental tax has a significant threshold effect on the link between green finance and CTI; when high levels of environmental taxes are maintained, the influence of green finance on enterprises' CTI is greatly strengthened, with an increase of 53%. GG will be further promoted by the advancement of enterprises' CTI. Finally, emerging counties would benefit from this study in designing frameworks of green finance, environmental tax, and CTI policies to achieve GG. [ABSTRACT FROM AUTHOR]

Exploitation of fossil fuel sources in the power generation and transportation sector has been a major source of carbon dioxide emissions that contributes to global warming. Replacement of hydrocarbon-based fuel sources with cleaner fuels is imperative for environmental preservation at the global level. In this regard, hydrogen can be used as an effective non-carbonaceous fuel option as well as an energy carrier. Canada is currently one of the economically advanced countries in the world and aims at achieving a net-zero economy by 2050. However, fossil fuels are still largely utilized for both transportation and power generation purposes. Slightly less than a quarter of the total grid power in Canada is supplied through fossil fuel combustion including natural gas, coal, and petroleum. As a matter of fact, Canada, as one of the top ten global producers of hydrogen, exhibits a great potential of achieving the goal of sustainable development. Thus, this paper discusses the current status, challenges, and opportunities offered by the hydrogen sector and its development in the near- and long-term future in Canada. The potential methods of hydrogen production in Canada are described by categorizing them according to the energy and feedstock sources required for their realization. In addition, the status of hydrogen storage and distribution in Canada is also discussed. Various sectors consuming hydrogen as the end-users in Canada are categorized based on hydrogen use as a fuel, a heating source, and an industrial feedstock and are comprehensively discussed. Several challenges and the necessary line-of-actions to establish a hydrogen economy in Canada in the long-term future are also discussed, and a road map for accomplishing the net-zero economy by 2050 is further explained based on achieving certain near-term, mid-term, and long-term goals. Moreover, the job creation opportunities in Canada are discussed by considering numerous critical sectors. [Display omitted] • Overview of Canada's global position with regards to hydrogen production. • Overview of Canada's natural resources and infrastructural potential. • Comprehensive discussion on hydrogen production pathways and end-use in Canada. • Identification of several key challenges to achieve net-zero economy by 2050.

According to social disorganization theory, a well-developed family and community structure is a pre-condition for low crime rates. Using annual data for 16 advanced countries constructed for two centuries, this paper examines the extent to which the changing family and community structures over the past two centuries have influenced the evolution of crime. Furthermore, we test whether a weakened family structure has a stronger effect on crime in communities with weak social networks by allowing for the interaction between urbanization (community network) and divorce rates (family network). Broadly, we find that changes in family and community structures and their interaction have been influential for the evolution of crime rates since 1810. [ABSTRACT FROM AUTHOR]

Buyers in developed countries often spend millions of dollars per year to ensure social compliance of their suppliers, yet the social performance of suppliers in developing countries remains poor. This paper discusses supplier social compliance in terms of adoption of public (e.g., SA 8000) and private (e.g., Walmart's supplier code of conduct) social standards and elaborates on the dynamics of standards adoption decision-making. Building upon ideas of asset specificity, social exchange, and organizational citizenship behavior, this paper develops propositions to provide an overarching framework explaining the adoption of public and private social standards. The paper shows that buyers and suppliers have different perspectives towards the adoption of public and private standards. Accordingly, the extent of supplier social compliance also varies based on the type of standard adoption. Further, adopting multiple social standards, i.e., both private and public, may not bring a corresponding increase in supplier social performance. Finally, from a buyer perspective, the selection of a particular social standard may require managing trade-offs. The findings can help managers in making better social compliance decisions. • Suppliers will prefer public standards due to their lower asset specificity. • Public standards decrease the transaction cost of the buyer. • Private standards allow buyers to customize social compliance requirements. • Public standards can trigger citizenship behavior in supplier employees. • Buyers trade-off cost with flexibility when choosing social standards.

Abstract Evidence suggests that manufacturing companies have tried to address the current environmental challenges derived from their operations by implementing various operational environmental sustainability approaches, including green manufacturing (GM), cleaner production (CP), green lean (GL), green supply chain management (GSCM), reverse logistics (RLs) and circular economy (CE). However, although their adoption is well documented in developed nations and few other countries, very little has been done to understand such phenomenon in a rapid developing country such as Thailand. This paper aims at filling this gap by providing light into some fundamental issues regarding the implementation of these approaches in the manufacturing sector of Thailand. A survey-based exploratory research was carried out based on 287 Thai manufacturing companies. The data was analysed using a combination of descriptive and inferential statics. The study revealed that a large amount of investment capacity, and proper training & knowledge are needed to fully implement the studied operational approaches. This resulted in some of the weakest elements of Thai manufacturing firms and hence the main barriers to their implementation. The study also showed that Thai manufacturing firms consider the impact on the environment and benefits from adopting these operational approaches as company's policy and own initiative, environmental awareness, and cost saving from conservation of energy as the main reasons for adopting the studied operational approaches. Finally, the findings also indicate that Thai manufacturing firms tend to implement them because of internal factors and that they lack of motivation from external factors and involvement from other stakeholders. The paper extends the current limited knowledge on the deployment of operational environmental sustainability approaches in Asia, and its results can be beneficial for organisations that aim at effectively adopting them to improve their operation's sustainability. Highlights • Evidence of the implementation of sustainability approaches in Thailand is limited. • Paper provides light into fundamental issues regarding their adoption. • 287 Thai manufacturing companies participated in this survey-based exploratory study. • Study reveals degree of implementation, main drivers and barriers of the studied approaches.

The relationship between managerial qualities and risk management is unclear, particularly for small and medium-sized organizations (SMEs) in developing market economies such as South Africa, because much research has focused on big enterprises in industrialized nations. To address this knowledge gap, this paper investigates the relationship between SME owner-manager characteristics and risk management, using upper echelons theory in a novel approach to provide a better understanding of how owner-manager characteristics may be linked to risk management strategies. This was achieved by the distribution of questionnaires to 320 purposely selected SMEs in Cape Town as well as personal interviews with two risk experts. The results show that risk avoidance is SMEs' most prevalent risk management strategy. The findings also show that SME owner-manager characteristics and risk management strategies are firmly and significantly linked, revealing the key determinants of effective risk management in SMEs. This paper is unique because it focuses on the often-overlooked topic of applying echelons theory to SMEs. Aside from bridging this knowledge gap, it has significant implications, such as informing SME owner-managers and policymakers on key variables that influence SME risk management strategies and making recommendations for future research.

As cities continue to expand and climate change exacerbates flooding, development within flood risk zones becomes an increasingly pressing concern. Engineered solutions alone cannot fully address the risks to individuals and communities, especially when local officials and residents have conflicting understanding of the risk. Participatory GIS (PGIS) offers a unique opportunity to bridge this gap by engaging with communities to better understand their perceptions of flood risk. While PGIS has traditionally been used in developing nations as an alternative to numerical flood models, its potential for use in developed nations is largely unexplored. This paper presents a case study of survey-based PGIS conducted in Reading, a large town in Berkshire, UK. Findings suggest that local residents possess a surprisingly accurate understanding of flood risk zones, but discrepancies with modelled flood risk were also identified. These discrepancies may be due to issues with cartographic representation, but also raise concerns about the accuracy of numerical flood models. By examining local perceptions of flood risk, this study highlights the importance of considering community perspectives in flood risk management and offers valuable insights for practitioners seeking to bridge the gap between modelled and perceived flood risk zones. • Participants show remarkably robust local knowledge of flood risk in a UK city. • Findings highlight the value of stakeholder engagement in FRM. • Participatory GIS can help bridge the gap between modelled and perceived flood risk. • Approach could help address conflicts between flood managers and stakeholders.

Cancer remains the primary cause of mortality in developed nations. Although localized tumors can be effectively addressed through surgery, radiotherapy, and other targeted methods, drug efficacy often wanes in the context of metastatic diseases. As a result, significant efforts are being made to develop drugs capable of not only inhibiting tumor growth but also impeding the metastasis of malignant tumors, with a focus on hindering their migration to adjacent organs. Cancer stem cells metastasize via blood and lymphatic vessels, exhibiting a high mutation rate, significant variability, and a predisposition to drug resistance. In contrast, endothelial cells, being less prone to mutation, are less likely to give rise to drug-resistant clones. Furthermore, the direct contact of circulating anti-angiogenic drugs with vascular endothelial cells expedites their therapeutic impact. Hence, anti-angiogenesis targeted therapy assumes a pivotal role in cancer treatment. This paper provides a succinct overview of the molecular mechanisms governing the interaction between cancer stem cells and angiogenesis. [ABSTRACT FROM AUTHOR]

• We analyze the impact of inward FDI on countries' economic complexity • We use a panel Granger causality and a panel VAR approach • Inward FDIs Granger cause economic complexity, and not viceversa • The short-run impact of FDI on economic complexity is very small • Knowledge-intensive greenfield FDI Granger cause economic complexity in developing countries In this paper, we assess whether attracting higher amounts of FDI induces a greater level of economic complexity in a country. Using a panel of 117 countries and 22 years, from 1995 to 2016, we test for the causal relationship between inward FDI and economic complexity using a panel VAR approach and Impulse Response Functions. We find that accumulating a higher stock of inward FDI per capita Granger-causes a greater economic complexity in a country, and not vice versa. This causal effect is very small, however, and occurs only in countries with above-average levels of GDP per capita, tertiary education, tertiarization or financial development. We also find that only greenfield FDIs Granger-cause economic complexity in developed countries. Finally, knowledge-intensive greenfield projects are the only type of FDI that Granger-cause complexity in a less developed country, but the estimated effect is near zero and disappears after two years.

• We analyse the long run relation between GDP per-capita growth and employment. • In the mid-1990s this relationship turned to be non-positive. • We found Jobless Growth and Decoupling between productivity and compensations. • Both can be explained by an inadequate aggregate demand growth. • Knowledge intensity of the economic sectors plays a key role. This paper is aimed at studying the long run relationship between GDP per capita growth and the job "required" by such a growth. This relationship, which has been positive for a long period after World War II, leading to a more equal and wealthy society via the labour market, turned out to be non-positive since the middle of the 1980s, giving rise to the so-called "Jobless Growth" and "Jobless Recovery" phenomena. By analysing data from STAN databases throughout the period 1970–2015, we found that the break in the relation between GDP per capita growth and employment can be explained by the decoupling between productivity from one hand, and labour compensation and utilisation from the other. Our findings further suggest that different economic sectors specifically contributed to the productivity change in accordance with their technological and knowledge intensity.

We use the Christensen, Diebold, and Rudebusch (2011) representation of the yield curve to test the functioning of the interest rate transmission mechanism along the yield curve based on government paper in advanced, emerging market, and low-income countries. We find a robust link from the policy and short-term interbank rates to the longer-term bond yields in all countries. Two policy implications emerge. First, the presence of well-developed secondary markets does not seem to affect transmission of short term rates along the yield curve. Second, the strength of the transmission mechanism seems to be affected by the choice of the monetary regime and the level of development: advanced countries with a credible inflation targeting regime seem to have better-behaved yield curves than the countries with other monetary regimes.

This paper theoretically constructs a simple model to study the effect of the structure of employment on the external trade balance. The paper illustrates that when the share of employment in services increases, the external trade deficit also increases, and this occurs due to the direct effect of the income and the indirect effect of the productivity. Empirically, the paper analyzes the effects of the structure of employment upon the external balance of goods and services in the panel dataset of 137 developing and developed countries for the period from 1960 to 2011. The paper finds that the external trade deficit has been rising with a higher share of the employment in services. [ABSTRACT FROM AUTHOR]

The continued relevance of the systems approach to the study of innovation, especially in developed countries, has been the subject of recent discourses. This paper argues that with respect to developing countries, discussions on innovation systems are yet to be exhausted. Against this background, the paper takes an objective look at the innovation systems approach and suggests an agenda for studying innovation systems in developing countries. The position of the paper is that modifications to the innovation systems approach present viable opportunities for understanding the innovation process in the developing world. Some concrete modifications, and their implications for future research, are proposed. [ABSTRACT FROM AUTHOR]

This paper presents downstream cost-benefit analysis for electronic waste (e-waste) recycling workers in Pakistan, a country that both generates large quantities of e-waste domestically and imports a significant amount from developed countries. Financial cost-benefit elements – reduction in productive capacity, lost wages, medical expenses, wages (and meals) and non-financial cost-benefit elements – opportunity cost, cost of illiteracy and value of life have been quantified. Primary data collected on site was analyzed using quantitative and qualitative methods. The estimated total net economic cost to recycling workers is between Rs.34,069 and Rs.85,478 (US$ 203–510 1 1 PKR to US$ conversion rate of 167.686 was used as of 1 July 2020.) per month or an average of Rs.50,363 (US$ 300) per worker. This main finding suggests that cost exceeds by 2.6–4.7 times the estimated economic benefits derived by these workers. Related qualitative data suggests government and owners of recycling businesses are largely blind to many of the less visible costs of this industry, while recycling workers and their families appear trapped in a vicious cycle of poverty. Understanding that what can be measured can be managed and improved, a systematic assessment of informal recycling based on identified impact factors may help mitigate and ideally also motivate a shift towards formal processing that would reduce the downstream negative impacts, both visible and hidden.

• The riding performance of all participants is significantly impaired at 0.05 BAC. • Novice participants perform higher mean speed and acceleration than experienced ones. • This study suggests to reduce the legal BAC limit for motorcyclists to zero. It is largely accepted that drink-driving significantly increases the likelihood that a driver may engage in risk-taking behavior and thus road crash. Although there have been a few studies examining the effect of blood alcohol concentration (BAC) on rider performance in developed countries, there has not been any research on the effect of BAC levels on motorcycle rider's performance in developing countries. This study is attempted to evaluate the effect of low BAC levels (i.e., ≤0.05 g/dL or 0.05) on riding performance of motorcycle riders in Vietnam using an advanced motorcycle riding simulator. Thirty-four motorcycle riders aged 18–40 complete simulated rides on three BAC levels, namely 0.00, 0.02, and 0.05. Riding performance indicators are measured and compared at different BAC levels. These indicators include average speed, average lateral overtaking distance, brake reaction time, acceleration, deceleration, and frequency of lane change. At the level BAC = 0.02 or lower, the negative effects on the rider's ability to control a motorcycle safely are statically insignificant. At the level BAC = 0.05, all the performances are impaired and the negative effects become statistically significant. In comparison of between novice participants and experienced participants at the same level of BAC, mean speed and acceleration rates of novice participants are significantly higher than the experienced participant. Based on the findings, the paper further discusses empirical relationships between reduced riding performances and road crash risk, and insights into drink-riding deterrence policy-making with regard to motorcycle riders.

Recovery from the recent financial crisis and "great recession" has been slower than after previous recessions in most developed countries and areas, especially Europe. But Europe's growth problem is structural in character and started much earlier. This paper analyzes the structural causes of the European slow growth, evaluates the policies that Europe adopted to overcome it, and concludes that even with the appropriate policies, the prospects for accelerating growth in Europe will be difficult, especially in the context of the current US-China trade war.

Background: Capnography is universally accepted as an essential patient safety monitor in high-income countries (HICs) yet is often unavailable in low and middle-income countries (LMICs). Increasing capnography availability has been proposed as one of many potential approaches to improving perioperative outcomes in LMICs. This scoping review summarises the existing literature on the effect of capnography on patient outcomes to help prioritise interventions and guide expansion of capnography in LMICs.Methods: We searched MEDLINE and EMBASE databases for articles published between 1980 and March 2019. Studies that assessed the impact of capnography on morbidity, mortality, or the use of airway interventions both inside and outside the operating room were included.Results: The search resulted in 7445 unique papers, and 31 were included for analysis. Retrospective and non-randomised data suggest capnography use may improve outcomes in the operating room, ICU, and emergency department, and during resuscitation. Prospective data on capnography use for procedural sedation suggest earlier detection of hypoventilation and a reduction in haemoglobin desaturation events. No randomised studies exist that assess the impact of capnography on patient outcomes.Conclusion: Despite widespread endorsement of capnography as a mandatory perioperative monitor, rigorous data demonstrating its impact on patient outcomes are limited, especially in LMICs. The association between capnography use and a reduction in serious airway complications suggests that closing the capnography gap in LMICs may represent a significant opportunity to improve patient safety. Additional data are needed to quantify the global capnography gap and better understand the barriers to capnography scale-up in LMICs. [ABSTRACT FROM AUTHOR]

This study provides a comprehensive analysis of the drivers of renewable energy production by employing variables of technological factors, economic factors, and environmental factors for two panels of developed and developing countries. Using GLS (Generalized Least Square) panel data estimation method, this paper finds that the determinants towards renewable sources vary in accordance with the level of income. The results reveal that renewable energy production is significantly determined by high technology export in developed countries, while high technology export is not statistically significant in explaining the use of RE sources in developing countries. Oil price has the smallest impact on renewable energy production in both groups. Although GDP per capita yields a positive impact on renewable energy production per capita in both groups, per capita CO 2 emission shows considerably different impacts in developed and developing countries. • Determinants toward renewables vary in accordance with the development level. • Technological factor and GDP mainly drive renewable energy use in developed countries. • GDP and CO 2 emission mainly drive renewable production in developing countries. • Technological factor cannot explain renewable energy dynamics in developing countries. • Oil price only marginally explain the dynamics of renewable energy production.

This paper examines the impact of labor regulation on total and youth employment of 108 countries over the timespan, 1996–2013. The methodology used is the dynamic panel data technique which distinguishes between short-run and long-run effects of legal change and takes into account dynamic interactions between legal and economic variables. It is observed that laws protecting the interests of labor do not hamper the long-term employment prospects of the general work force and the youth population. By and large this result holds in the two sub-samples: one consisting of 23 developed countries and the other consisting of 85 less-developed countries. [ABSTRACT FROM AUTHOR]

• Financial liberalization and years since last regulatory reforms increase banking crisis vulnerability. • Financial liberalization- banking instability (crisis) link depends largely on the regulatory framework updating. • Regulatory delays- banking instability (crisis) relationship depends on the level of financial liberalization. • The relationship between financial liberalization and banking system vulnerability can be illustrated by a U-Shaped relationship according the number of years since last regulatory reforms. Similarly, the link between years since the last reform and banking system situation can be estimated by a U-Shaped curve depending on the level of financial liberalization. This paper aims at bringing new insights concerning the effect of financial reforms on banking system vulnerability. We show that the link between financial liberalization and banking crisis depends on the number of years since last regulatory reforms. Similarly, we show that updating regulations indirectly affect banking crisis according to the financial liberalization level. Then, we show that banking crisis can be largely explained by a gap between financial innovations and regulation update on a sample of 49 developed and developing countries from 1980 to 2010. Our empirical evidence supports that the regulatory environment is more important in developed countries as it reduces banking fragility perhaps because of highly-risky exchanged financial products. The effect of financial liberalization depends largely on the number of years since last reform. However, destabilizing effect of financial liberalization in developing countries cannot be neutralized by updating regulations and gets more obvious as regulations become older.

• Intrinsic permeability of Chinese MSW is tested under both liquid and gas flow. • Testing results are compared with reported data from raw and MBT MSW. • The influences from waste composition, porosity and particle size are studied. Changing patterns of municipal solid waste (MSW) management, for example sorting for recycling and mechanical–biological treatment (MBT), will change the nature of the residual material going to landfill and in particular its intrinsic permeability. This is an important parameter, not least because of its influence on gas and leachate flows and the ramifications for gas and leachate management. This paper reports the results of laboratory permeability tests on specimens of MSW recovered from boreholes drilled in a Chinese landfill, under both liquid and gas flow. The test results are used to assess the intrinsic permeability of the waste, and are compared with corresponding data from raw and MBT municipal solid wastes from developed countries in the context of differences in waste composition, porosity and particle size. For the Chinese waste, the intrinsic permeability decreased with depth, while at a given depth the permeability determined with gas flow was consistently larger than that determined with liquid flow. Intrinsic permeabilities determined in liquid flow showed no clear trend of variation with effective particle diameter d 10 , but reduced with drainable porosity (the drainable porosity, n e , being a more appropriate and useful measure than the total porosity, n). Conversely, intrinsic permeabilities determined in gas flow showed a clear decrease with decreasing d 10 , but no consistent variation with porosity. These differences are potentially significant in assessing the impacts and interactions between gas and liquid flows; some reasons for them are suggested. [ABSTRACT FROM AUTHOR]

Mathematical modelling plays an important role in food engineering having various mathematical models tailored for different food topics. However, mathematical models are followed by limited information on their application in food companies. This paper aims to discuss the extent and the conditions surrounding the usage of mathematical models in the context of European food and drinks industry. It investigates the knowledge, nature and current use of modelling approaches in relation to the industry main characteristics. A total of 203 food companies from 12 European countries were included in this research. Results reveal that the country where the company operates, and size of the company, are more important predictors on the usage of mathematical models followed by the type of food sector. The more developed countries are positioned at the higher level of knowledge and use of available models. Similar pattern was observed at the micro level showing that small or medium sized companies exhibit lack of knowledge, resources and limiting usage of models. • 203 food companies from 12 European countries were included in this research. • Use of mathematical models in food companies is on a low level. • Most food models are not "user-friendly" for food companies. • Higher level of knowledge and use of models is in developed countries. • Lower level of knowledge and use of models is in small and medium sized companies.

Autonomous driving is the future of the automotive industry across the globe. Many challenges must be resolved in designing and developing successful Autonomous Driving Systems (ADS), especially in developing countries with poor road infrastructure. Detecting obstacles in lanes is essential for robust ADS to decide whether to change lanes, slow down, or even stop. Developing countries like India present challenges, including poor or no lane line demarcation, poor traffic management, and diverse driving behaviors. That brings many challenges to developing robust lane-keeping or lane-changing decision systems in an ADS. Publicly available driving datasets have an inherent bias towards the road infrastructure of developed countries and hence cannot cater to the needs of the Indian requirements. That makes the existing obstacle-lane segment detection models unsuitable for road infrastructures in developing countries. Due to these factors, the rate of advancement of ADS and Advanced Driver Assistance Systems (ADAS) in developing countries is meager compared to other developed countries. This makes it even more critical for future research to focus on these developing countries. This paper proposes a deep-learning-based novel decision-making network named LaneScanNET to assist the ADS in lane-changing or lane-keeping decision-making. The proposed system assists ADS in detecting obstacles, localization of the Ego Vehicle (EGV) on roads, and estimating lane status in its Field of View (FOV). The proposed LaneScanNET uses a parallel pipeline with an Obstacle Detection Network (ODN) and a Lane Detection Network (LDN) to simultaneously process the incoming image frames for detecting obstacles and segmenting lane lines, respectively. Further, the Obstacle-Lane Fusion Network (OLFN) fuses these results to predict the status of the obstacle lane in the FOV of autonomous vehicles. Vellore Institute of Technology's (VIT's) real-time driving dataset on indigenous roads has been collected to train the proposed LaneScanNET with 2464 obstacle-lane images obtained by driving over 60 km. The dataset generated for obstacle detection and its corresponding lane detection has also been made publicly available to promote research work for these developing countries. The proposed system outperforms all existing networks on Indian roads with an accuracy of 75.28% in obstacle detection and 91.36% in lane detection. Additionally, the proposed system can analyze the lane status with an accuracy of 92.54%. The proposed network performs exceptionally well in unforeseen circumstances like shadows, fog, dust, and occlusions making LaneScanNET a robust network that can be an add-on for ADS to make lane-keeping or lane-changing decisions. The LaneScanNET can be integrated into real-time vehicles to assist drivers or ADS. [ABSTRACT FROM AUTHOR]

The Sustainable Development Goal (SDG) that emphasizes sustainable and affordable energy presents a practical pathway to achieve sustainable growth. Moreover, this goal aligns with SDG 13, which focuses on climate action. Nonetheless, it is important to consider factors such as political and financial risk, as they can influence climate action efforts and the renewable energy sources adoption. Hence, this study broadens the conversation surrounding CO 2 emission reduction and the achievement of Sustainable Development Goals (SDGs). It accomplishes this by investigating the interplay between renewable energy, political risk, financial risk, and CO 2 emissions in Finland spanning from 1990/Q1 to 2021/Q4. Notably, this research distinguishes itself through its exploration of these complex connections, employing a wavelet-based quantile methodology. Unlike traditional quantile regression, which can only reveal connections between variables within each quantile, the wavelet-based quantile approach enables the simultaneous capture of correlations across quantiles and periods. The results show that in the long-term and across all quantiles (0.01–0.99), energy efficiency, specifically gas and oil efficiency, lessens CO 2. In addition, low financial and political risks improve ecological quality by lessening CO 2 across all periods and quantiles (0.01–0.99). The paper outcomes serve as a basis for formulating a policy framework aimed at achieving SDG 7 and SDG 13 in Finland. • We explore the impact of energy efficiency and country risk on CO 2 emissions. • The role of renewable energy and economic growth are also analyzed. • The Time series data of the Finland is used from 1990/Q1 to 2020/Q4. • Various wavelet-based quantile correlation is applied. • Renewable energy, oil and gas efficiency decrease CO 2 emissions in each quantile and across periods.

Prior research on overwork has predominantly been conducted in developed countries. This study examines the role of affordable housing in Chinese cities and provides evidence from a developing country. Using data from China's National Health and Family Planning Commission's "China Migrants' Dynamic Survey," this study explores the relationship between affordable housing and overwork among migrant workers in Chinese cities, as well as the mechanism underlying this association. The results imply that migrant workers in China can work fewer hours if they reside in affordable housing. The impact of affordable housing on the overwork of migrant workers is partially mediated by their housing cost burden and their sense of local self-identity. Women, the younger generation, and later-arriving migrant workers are more negatively affected than men, the older generation, and earlier-arriving migrants. This study gives insight into the evaluation of the efficiency of affordable housing in China and evidence for future research on the issue of overwork in developing nations. • This study evaluates the effect of affordable housing on migrant workers' overwork in China. • The impact of affordable housing reduces migrant workers' overwork occurs partly through their housing cost burden and self-identity. • CMP, PSM and IV are applied to control endogeneity problems and perform robustness checks. • Conventional labor economic theory and identity economic theory are introduced to this paper.

Sustainable development requires more investment in sustainable companies and less in unsustainable firms. However, the factors driving sustainable investing are not well understood. To address this gap, this paper uses institutional theory to examine three determinants of sustainable investing: (1) investor commitment to sustainable investing initiatives; (2) normative pressure; and (3) home-country influences. The findings indicate that sustainable investing initiatives do not guarantee more sustainable asset allocation among members. Normative pressure correlates with reduced investment in unsustainable companies. Investors from home-countries with legal systems prioritizing diverse stakeholders, and with governments committed to achieving the Sustainable Development Goals (SDGs), tend to invest less in unsustainable companies. Conversely, investors from countries with limited SDG progress show higher investment in unsustainable firms, while those from more developed nations invest more in sustainable companies. These results highlight the need for a critical examination of institutional efficacy in promoting sustainable investing. [ABSTRACT FROM AUTHOR]

The interest for food waste (FW) in the scientific community has been growing consistently in the most recent years. This is reflected by the number of publications (journal articles and proceedings papers) which can be accessed in the Web of Science (WoS) database. However, lacking of systematic, chronological and synthesizing studies indicating how this field has evolved over time. The main objective of this paper is to consolidate the state of the art of research on FW, based on a bibliometrics study of articles published over the past 18 years. The results are discussed under the following perspectives: chronological distribution, countries, institutions, source titles, subject categories, and author keywords. It is found that the FW research has increased rapidly over past 18 years, most notably in the last 8 years. In total, 2340 research articles were published in 801 journals and in 161 WoS subject categories. The top 7 productive countries were analyzed herein. The predominance of Chinese institutions in terms of article count and a predominance of industrialized countries' institutions in terms of citation score were compared. Finally, based on keywords analysis, it comes to the conclusion that the clean energy, treatment and valorization, and management innovation have attracted extensive attention during the past decade.
