AbstractA review of the natural analog study at the Akrotiri archaeological site is provided with regard to its use in support of long-term predictive modeling of chemical transport. Evidence for a plume of contaminants was collected using samples taken from the area under the location where artifacts were buried in silicic tuff for 3600 years. A transport model was developed using site characterization data, but no data for the plume. Qualitative data from the field support the model result that flux of metals from the artifacts was small. However, transient transport characteristics and the role of notable system heterogeneities and complexities were not fully represented by the model. The Akrotiri natural analog study indicates that long term releases and transport may be limited in an unsaturated repository site, but releases may be strongly affected by unknown processes or processes that are neglected in simplified models.

Marriage has long been linked to lower risk for adult mortality in population and clinical studies. In a regional sample of patients ( n = 569) undergoing cardiac surgery, we compared 5-year hazards of mortality for married persons with those of widowed, separated or divorced, and never married persons using data from medical records and psychosocial interviews. After adjusting for demographics and pre- and postsurgical health, unmarried persons had 1.90 times the hazard of mortality of married persons; the disaggregated widowed, never married, and divorced or separated groups had similar hazards, as did men and women. The adjusted hazard for immediate postsurgical mortality was 3.33; the adjusted hazard for long-term mortality was 1.71, and this was mediated by married persons’ lower smoking rates. The findings underscore the role of spouses (both male and female) in caregiving during health crises and the social control of health behaviors.

How much coal will India need to transport in future and is the rail network poised to handle that requirement are two important questions for the emerging economy. To find answers to these questions, this study creates a distribution model of coal freight traffic on Indian Railways, analyzing the sufficiency of infrastructure for future economic needs. Using data on spatial distribution of coal mines, coal traffic volumes and rail sectional capacities, this study creates sectional capacity maps as main visual tool for analysis. Sections with bottlenecks are identified for next ten years’ coal transport need of the country. The simulation done in this study finds 15% under-delivery for the 900mT coal demand in the country by 2030 due to transport bottlenecks. Based on this analysis, the article presents the conclusions on possible influence of existing conditions of coal transportation on India’s economy in the long-term period and also considers the role of dedicated freight.

AbstractWhile gender gaps in political participation are pervasive, especially in developing countries, this study provides systematic evidence of one cultural practice that closes this gap. Using data from across Africa, this article shows that matrilineality – tracing kinship through the female line – is robustly associated with closing the gender gap in political participation. It then uses this practice as a lens through which to draw more general inferences. Exploiting quantitative and qualitative data from Malawi, the authors demonstrate that matrilineality's success in improving outcomes for women lies in its ability to sustain more progressive norms about the role of women in society. It sets individual expectations about the gendered beliefs and behaviors of other households in the community, and in a predictable way through the intergenerational transmission of the practice. The study tests and finds evidence against two competing explanations: that matrilineality works through its conferral of material resources alone, or by increasing education for girls.

Abstract. Organic aerosol (OA), with a large biogenic fraction in summertime southeast US, adversely impacts on air quality and human health. Stringent air quality controls have recently reduced anthropogenic pollutants including sulfate, whose impact on OA remains unclear. Three filter measurement networks provide long-term constraints on the sensitivity of OA to changes in inorganic species, including sulfate and ammonia. The 2000–2013 summertime OA decreases by 1.7~1.9 %/year with little month-to-month variability, while sulfate declines rapidly with significant monthly difference in early 2000s. In contrast, modeled OA from a chemical-transport model (GEOS-Chem) decreases by 4.9 %/year with much larger month-to-month variability, largely due to the predominant role of acid-catalyzed reactive uptake of epoxydiols (IEPOX) onto sulfate. The overestimated modeled OA dependence on sulfate can be improved by implementing a coating effect and assuming constant aerosol acidity, suggesting the needs to revisit IEPOX reactive uptake in current models. Our work highlights the importance of secondary OA formation pathways that are weakly dependent on inorganic aerosol in a region that is heavily influenced by both biogenic and anthropogenic emissions.

Purpose – The purpose of this paper is to present a discussion of the value of early diversion schemes, underpinned by the principles of restorative justice (RJ), for First Time Entrants (FTEs) into the criminal justice system (CJS). Design/methodology/approach – The paper focuses specifically on the findings of a 12-month study into the introduction of “Triage” by one Youth Offending Team (YOT) in the northeast of England. Findings – Re-offending data suggested that Triage is more effective in reducing re-offending than conventional justice practices, due to the restorative nature of the scheme. However, the qualitative data raised a number of issues, particularly relating to problems of “net-widening” and the impact of recording processes on young people's desistance, as well as the role of victim engagement in the process. These issues could undermine the long-term effectiveness of Triage and its successful application within other youth justice contexts. Originality/value – The paper aims to contribute further understanding regarding the impacts of RJ practices on reducing re-offending compared to traditional processes, and in particular, consider the role of implementation issues in the production of outcomes and impacts.

During the recent inflow of asylum seekers from the Middle East and North Africa to Europe, the native population in Greek frontier islands largely offered humanitarian assistance to these immigrants, while support for their permanent settlement in the area was low. To explain this discrepancy, we investigated whether sympathy toward asylum seekers, perceptions of threat posed by asylum seekers, and asylum seekers’ perceived societal contributions relate differently to native Greeks’ self-reported provision of humanitarian assistance and to their support for asylum seekers’ permanent settlement in Greece. Using data from a representative sample of 1,220 Greek participants, we found that Greeks who showed more sympathy toward asylum seekers were more likely to report having offered humanitarian assistance. Further, participants who felt more sympathy and those who perceived higher asylum seekers’ contributions were more positive toward asylum seekers’ permanent settlement, whereas participants who perceived more threat from asylum seekers showed less support for their permanent settlement. We conclude that policies geared toward motivating people to provide humanitarian aid to asylum seekers should focus on generating sympathy, whereas policies geared toward increasing long-term acceptance of asylum seekers need to additionally consider lowering threat perceptions and highlighting asylum seekers’ contributions.

AbstractThis paper investigates the role of large outbreaks on the persistence of Covid-19 over time. Using data from 650 European regions in 14 countries, I first show that winter school holidays in late February/early March 2020 (weeks 8, 9 and 10) led to large regional outbreaks of Covid-19 in the spring with the spread being 60% and up-to over 90% higher compared to regions with earlier school holidays. While the impact of these initial large outbreaks fades away over the summer months, it systematically reappears from the fall as regions with school holidays in weeks 8, 9 and 10 had 30–70% higher spread. This suggests that following a large outbreak, there is a strong element of underlying (latent) regional persistence of Covid-19. The strong degree of persistence highlights the long-term benefits of effective (initial) containment policies, as once a large outbreak has occurred, Covid-19 persists. This result emphasizes the need for vaccinations against Covid-19 in regions that have recently experienced large outbreaks but are well below herd-immunity, to avoid a new surge of cases.

Issue: The constrains to obtain a capital often involving underprivileged entrepreneurs because it is difficult to get a fund from the financial institutions. From a Muslim entrepreneur's perspective, microfinance that offered is consisting element of riba and it is prohibited in Islam. As we know, the role of zakat is huge in the economy of the Muslims. So, effective zakat distribution system is able to organize and develop society. Especially for Muslim underprivileged entrepreneurs.  Purpose of study: This article aims to analyze first, what is the basis for the establishment of zakat distribution law over the provision of capital through microfinance? Second, is this distribution potentially to be implemented in Malaysia? Methodology: Qualitative data were obtained from document analysis and interview with zakat expertise in Malaysia. Main findings: Based on the content analysis on primary data, the findings show that there is a strong legal basis allowing zakat distribution through micro-financing. According to scholars' views in Malaysia, the distribution of zakat through microfinance has the potential to be implemented in Malaysia. Implications: The distribution of zakat is not limited to self- sufficiency even can be distributed through productive zakat with the provision of initial capital and revolving capital from zakat funds through microfinance. The provision of working capital through microfinance from zakat funds is a long-term goal of zakat. Novelty/originality: Yet, there is no zakat distribution is done through microfinance in Malaysia. Therefore, the institutions of zakat in Malaysia adopt the Baitul Mal Aceh as a model to apply the granting of working capital in the form of micro-financing which is financed from the funds of zakat. Furthermore, scholars in Malaysia also argued that the distribution of such method has great potential to be implemented in Malaysia.

Purpose of Study: The paper aims to assess the new face of retailing after demonetization with specific focus to the role of financial intermediaries and it also focuses on Long term solutions to drive the digital cash enabled retailing in India. Methodology: This study used a questionnaire for data collection among 250 retailers in Uttarakhand, India. The questionnaire was later on analyzed using SPSS. Qualitative data was gathered from the interview with the officials from 100 financial intermediaries from banks. Findings: The Indian retail market has been fostered by the cash dealings. The step of demonetization caught the black marketers, retailers and common people by surprise. The move was supported by the majority of people despite facing difficulties.  After the demonetization, people started using the adoption of different forms of digital payment options. The trade in the market was affected and the retail sales witnessed a severe dip. The market is recovering but the actual recovery will depend on devising the substitute for the cash payments at all levels of retailers. Social implications: Financial inclusion is important for inclusive growth and bank to have a crucial role to play in financial literacy campaigns and should ensure that those deprived sections that come to exchange their old notes are properly taken care of. Banks could make unbanked people aware about the financial instruments available with banks and the importance of saving and putting their money in these instruments. This step would further help the economy move from unorganized to organized sector. The originality of Study: This study is original and first of its kind conducted in Uttarakhand, India.

AbstractThis study examines friendship and hostility relations between Roma students and the ethnically homogeneous non-Roma majority in Hungarian schools. Using data on friendship and hostility relations of 15-year-old students from 82 schools, the study focuses on the interaction between exposure to the other ethnic group and academic achievement of Roma students. High-achieving Roma students are shown to have significantly more friends and fewer adversaries than low-achieving ones, due to better inter-ethnic relations while having similar within-ethnic group relations. As a result, higher exposure to Roma students translates to more friendship and less hostility from non-Roma students in environments where more of the Roma students have higher achievement. Therefore, policies helping the achievement of Roma students can have immediate as well as long-term positive effects. Simulations suggest that a mixed policy of desegregation and closing the achievement gap may best foster positive inter-ethnic relations.
