AbstractBy 2050, the cumulative mass of end-of-life photovoltaic (PV) modules may reach 80 Mt globally. The impacts could be mitigated by module recycling, repair and reuse; however, previous studies of PV circularity omit the consideration of critical social factors. Here we used an agent-based model to integrate social aspects with techno-economic factors, which provides a more realistic assessment of the circularity potential for previously studied interventions that assesses additional interventions that cannot be analysed using techno-economic analysis alone. We also performed a global sensitivity analysis using a machine-learning metamodel. We show that to exclude social factors underestimates the effect of lower recycling prices on PV material circularity, which highlights the relevance of considering social factors in future studies. Interventions aimed at changing customer attitudes about used PV boost the reuse of modules, although used modules can only satisfy one-third of the US demand during 2020–2050, which suggests that reuse should be complemented by recycling.

Abstract By 2050, the cumulative mass of end-of-life photovoltaic (PV) modules may reach 80 million metric tons globally. The impacts could be mitigated by circular economy (CE) strategies including module recycling, repair, and reuse. However, previous studies of PV circularity omit consideration of critical social factors. We use a novel agent-based model to integrate social aspects with techno-economic, factors—providing a more realistic assessment of circularity potential for previously studied CE interventions and assessing additional interventions that cannot be analyzed using techno-economic analysis alone. We also performed a global sensitivity analysis using a machine-learning metamodel. We show that excluding social factors underestimates the effect of lower recycling prices on PV material circularity. Interventions aimed at changing customer attitudes about used PV boost module reuse, although used modules can only satisfy a third of US demand during 2020–2050, suggesting that reuse should be complemented by recycling.

The past ten years have witnessed a revival in scholarship on militarism, through which scholars have used the concept to make sense of the embeddedness of warlike relations in contemporary liberal societies and to account for how the social, political and economic contours of those same societies are implicated in the legitimation and organization of political violence. However, a persistent shortcoming has been the secondary role of race and coloniality in these accounts. This article demonstrates how we might position racism and colonialism as integral to the functioning of contemporary militarism. Centring the thought and praxis of the US Black Panther Party, we argue that the particular analysis developed by Black Panther Party members, alongside their often-tense participation in the anti–Vietnam War movement, offers a strong reading of the racialized and colonial politics of militarism. In particular, we show how their analysis of the ghetto as a colonial space, their understanding of the police as an illegitimate army of occupation and, most importantly, Huey Newton’s concept of intercommunalism prefigure an understanding of militarism premised on the interconnections between racial capitalism, violent practices of un/bordering and the dissolving boundaries between war and police action.

AbstractA contact-tracing strategy has been deemed necessary to contain the spread of COVID-19 following the relaxation of lockdown measures. Using an agent-based model, we explore one of the technology-based strategies proposed, a contact-tracing smartphone app. The model simulates the spread of COVID-19 in a population of agents on an urban scale. Agents are heterogeneous in their characteristics and are linked in a multi-layered network representing the social structure—including households, friendships, employment and schools. We explore the interplay of various adoption rates of the contact-tracing app, different levels of testing capacity, and behavioural factors to assess the impact on the epidemic. Results suggest that a contact tracing app can contribute substantially to reducing infection rates in the population when accompanied by a sufficient testing capacity or when the testing policy prioritises symptomatic cases. As user rate increases, prevalence of infection decreases. With that, when symptomatic cases are not prioritised for testing, a high rate of app users can generate an extensive increase in the demand for testing, which, if not met with adequate supply, may render the app counterproductive. This points to the crucial role of an efficient testing policy and the necessity to upscale testing capacity.

Background: Social apathy, a reduction in initiative in proposing or engaging in social activities or interactions, is common in mild neurocognitive disorders (MND). Current apathy assessment relies on self-reports or clinical scales, but growing attention is devoted to defining more objective, measurable and non-invasive apathy proxies. Objective: In the present study we investigated the interest of recording action kinematics in a social reach-to-grasp task for the assessment of social apathy. Methods: Thirty participants took part in the study: 11 healthy controls (HC; 6 females, mean age = 68.3±10.5 years) and 19 subjects with MND (13 females, mean age = 75.7±6.3 years). Based on the Diagnostic Criteria for Apathy, MND subjects were classified as socially apathetic (A-MND, N = 9) versus non-apathetic (NA-MND, N = 10). SensRing, a ring-shaped wearable sensor, was placed on their index finger, and subjects were asked to reach and grasp a can to place it into a cup (individual condition) and pass it to a partner (social condition). Results: In the reach-to-grasp phase of the action, HC and NA-MND showed different acceleration and velocity profiles in the social versus individual condition. No differences were found for A-MND. Conclusion: Previous studies showed the interest of recording patients’ level of weekly motor activity for apathy assessment. Here we showed that a 10-min reach-to-grasp task may provide information to differentiate socially apathetic and non-apathetic subjects with MND, thus providing a tool easily usable in the clinical practice. Future studies with a bigger sample are needed to better characterize these findings.

Islam is embraced by many people through a relatively fast spread. This fact cannot be separated firom the role of its preacher, Muhammad. His success in da’wa activities was contributed by his social roles as well as the revelation that he brought. This article tries to explain that both the revelation and the social factors greatly supported his da’wa. Beside his positives, the existence of Quran as a revelation contributed the social legitimacy that Muhammad was considered as a figure to be followed in spite of his contrary values to the cultures of his time.

The present paper aims to explain crime by investigating various theoretical approaches and to show that from the classic era to the recent postmodern theories, a slow but steady cycle of discourse concerning crime has been occurring. In the classic times, the criminal is assumed to be a sane person with sound will who commits crime with an individualistic choice and due to incorrect decisions; In the positivism approach, the theorists' concern is directed at recognizing criminals and clarifying more fundamental biological aspects and psychological performance and they seek to explain the phenomenon of crime by dividing the people of the society into normal and abnormal people; In the modern theories the social factors causing the appearance of crime are at the focal point while critical theories greatly emphasize on the role of the society in the criminal phenomenon and its definition, finally postmodern theories consider crime totally as constructed by mindset, language and power and question its existential reality.

<p>     The development of geothermal exploration has benefited from the inclusion of exploration protocols based on geological Plays classically used in hydrocarbon exploration projects. Despite being a research topic in which many efforts have been devoted, it presents weaknesses when evaluating the role of the communities (the social dimension) during the exploration process. To address the lack of studies, a qualitative research has been carried out in Central America (Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panamá) to determine the necessary factors to be considered in the social dimension within the geothermal exploration based in Plays.</p><p>     We have identified the social factors within each social dimension (demand, infrastructure, land access) and from this, a catalogue of the necessary activities required in the social dimension during the geothermal exploration process based on plays is proposed. The results of our survey will greatly contribute to the implementation of the Play-based exploration in geothermal projects because it reduces the risks associated in the initial phase of the exploration process and offers a step-by-step methodology that, when adapted to the needs of each country, can improve the efficiency of the current geothermal exploration protocols.</p>

Sport provides a context in which mate choice can be facilitated by the display of athletic prowess. Previous work has shown that, for females, team sport athletes are more desirable as mates than individual sport athletes and non-participants. In the present study, the perceptions of males and females were examined regarding potential mates based on sport participation. It was predicted that team sport athletes would be more positively perceived than individual sport athletes and non-participants by both males and females. A questionnaire, a photograph, and manipulated descriptions were used to gauge perceptual differences with respect to team sport athletes, individual sport athletes, and extracurricular club participants for 125 females and 119 males from a Canadian university. Both team and individual sport athletes were perceived as being less lazy, more competitive, and healthier than non-participants by both males and females. Interestingly, females perceived male athletes as more promiscuous than non-athletes, which upholds predictions based on previous research indicating (a) athletes have more sexual partners than non-athletes, and (b) females find athletes more desirable as partners than non-participants. Surprisingly, only males perceived female team sport athletes as more dependable than non-participants, and both team and individual sport athletes as more ambitious. This raises questions regarding the initial hypothesis that male team athletes would be perceived positively by females because of qualities such as the ability to cooperate, likeability, and the acceptance of responsibilities necessary for group functioning. Future studies should examine similar questions with a larger sample size that encompasses multiple contexts, taking into account the role of the social profile of sport in relation to mate choice and perception.

This study examines the role of social parameters in the choice of address forms used in kinship domain in Punjab, Pakistan. The study targeted 140 respondents in order to test the impact of social factors along with the regional differences in the choices of address forms in kinship domain. Statistical analyses are done by applying t-test for gender in relation to choices of address forms and ANOVA for age, income, education and social class. The study finds out that there is a strong connection of different social parameters not only with language use and practice but also in choices and use of address forms especially in kinship relationships.  Moreover, it is highlighted that gender does not influence in the choices of address forms, even the participants belonging to young and middle categories show no significant difference with regard to the choices of address form despite the fact that all the factors and parameters exert influence on the choices of address forms. Hence address forms as being one of the major traits of language and society is affected by all the social factors around and regional differences are also most important as they give identity and ethnicity to the society.
