Competition resulting in high social status and maintenance of that status within farmed pigs may have both welfare and economic consequences. Aggressive behaviours, associated with the establishment and maintenance of a dominance hierarchy, may cause poor welfare and skin damage reducing the value of pigs at slaughter. In order to investigate the impact of social status on welfare we first need to establish the status of individuals relative to their peers. In this paper we compare two alternative indicators of pig rank, namely: (i) aggressive interactions between individuals - the occurrence of aggressive behaviour from pig A to pig B is often assumed to imply social dominance of pig A over pig B; and (ii) the order in which pigs stand at the feeder - an advantage of attaining high social status in many populations is priority of access to food. Social rank of individuals based on observed aggressive behaviour can only be assigned once evidence for a linear or quasi-linear hierarchy has been established (Langbein and Puppe, 2004). In a population with a purely hierarchical structure we expect all triads of individuals to be transitive, that is A→B, B→C implies A→C. For observational studies it is unlikely that interactions between all individuals will be observed. Here we present a novel methodology by which we can assess the linearity of the dominance structure that is not affected by missing or null interactions between individuals. By conducting a census of all types of triad in a social network we can assess whether the subset of interactions observed provide evidence of a linear or quasi-linear hierarchy. Transitive triads provide evidence of linear hierarchy whilst intransitive triads, such as A→B, B→C, C→A, contradict the presence of a linear hierarchy.

The Sea Dayaks, better known as the Ibans, inhabit nearly the whole of Sarawak. The Ibans belong to the Proto-Malay groups and historically, they were from the Kapuas Valley in West Kalimantan, Indonesia. They migrated to Sarawak about fifteen generations ago in the mid 16th century (the 1630s). They went to the state through the Kumpang Valley and inhabit Batang Ai and then split to several places in Sarawak (Morgan, 1968). Although the Ibans have a social status in their traditional belief, they do not have a hierarchy of social status such as the Orang Ulu. However, they have elevated the status so-called Pengulu, Tuai Rumah, Tuai Burung, Lemambang, Manang, Beliau, Tukang Sabak, dan Indu Takar. The era of modernization has led to changes to the knowledge of the young generation, especially the younger generation of the Ibans who lack knowledge about the function and role of each rank status in their communities. Therefore, this study was conducted qualitatively through an interview with expert informants, observation, and documentation. This research was hoped to contribute to the general knowledge of the Iban community and other communities in the preservation of the function and role of each social status in the Iban community.

Abstract Introduction Growing research supports the use of older volunteers to provide respite and community-based assistance to persons with ADRD and their caregivers. This study explores the impact of COVID-19 on a face-to-face, peer-led psychoeducational intervention for African American ADRD family caregivers, the Senior Companion Program Plus (SCP-Plus), and its subsequent need to ‘pivot’ during the pandemic. Method: The SCP-Plus was a randomized control trial across three states that assessed program impact on ADRD family caregiver stress/burden, coping, and social support. In spring 2020, the SCP-Plus intervention was halted because of the potential risk to participants due to COVID-19 (n = 20 enrolled dyads). In an effort to maintain rapport and trust, critical to retention in research studies, team members began weekly (March-April) and then bi-weekly calls (May-December) for the purpose of providing a social check-in and to provide updates on the status of the intervention. Results A total of 396 calls lasting approximately 10 minutes each were completed. Participants shared concerns around safety, access to food/supplies/masks/testing, feelings of stress and loss, concern for others, and the importance of technology as a means of social connection. Although the intervention aspect of the SCP-Plus ultimately ended due to COVID-19, information gleaned from these check-ins were used to pivot the study. The study moved forward by using a descriptive phenomenological approach to capture dyads’ lived experiences during COVID-19. Discussion Overall, purposeful participant engagement through weekly/bi-weekly phone calls suggests that this is a promising strategy for participant retention as well as for pivoting research.

Abstract The reproductive biology of many female mammals is affected by their social environment and their interactions with conspecifics. In mammalian societies structured by linear dominance hierarchies, such as that of the spotted hyena (Crocuta crocuta), a female’s social rank can have profound effects on both her reproductive success and her longevity. In this species, social rank determines priority of access to food, which is the resource limiting reproduction. Due largely to rank-related variation in access to food, reproduction from the perspective of a female spotted hyena can only be understood in the context of her position in the social hierarchy. In this review, we examine the effects of rank on the various phases of reproduction, from mating to weaning. Summed over many individual reproductive lifespans, the effect of rank at these different reproductive phases leads to dramatic rank-related variation in fitness among females and their lineages. Finally, we ask why females reproduce socially despite these apparent costs of group living to low-ranking females. Gregariousness enhances the fitness of females regardless of their positions in the social hierarchy, and females attempting to survive and reproduce without clanmates lose all their offspring. The positive effects of gregariousness appear to result from having female allies, both kin and non-kin, who cooperate to advertise and defend a shared territory, acquire, and defend food resources, maintain the status quo, and occasionally also to rise in social rank.

Purpose The economic consequence for adopting accounting standards is one of the growing and valuable topics in accounting research. The purpose of this paper is to address the question whether the adoption of Islamic standards that are issued by Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFIs) has a positive effect on the level of earnings management (EM) in the Islamic banks (IBs) setting. The authors measure, in general, the impact of AAOIFI for adopter and non-adopter banks. This paper furthermore investigates whether IBs adopting AAOIFI as compulsory or as voluntary adopters, in general, are being less engaged in earnings manipulation. Design/methodology/approach Using empirical data from 143 IBs across 26 different countries from 2014 to 2018, the paper uses a linear regression model and probit regression analysis that group the banks investigated in this paper into adopters and non-adopters. Additional probit regressions were performed to test to what extent the status of AAOIFI adoption (compulsory or voluntary adopters) has an impact of EM. Findings The adoption of AAOIFI generally is associated with a reduction in the EM level. Furthermore, adopter IBs for AAOIFI is least involved in EM as compared to non-adopter IBs. In addition, the findings of this paper indicate that IBs across countries that mandate AAOIFI standards are less engaged in earnings manipulation as compared to other IBs in countries that adopt AAOIFI as voluntary standards. Research limitations/implications The results reported in this paper provide insights to central banks and regulators regarding the prominence of mandates of AAOIFI standards for IBs to enhance the trust level of stakeholders by reducing the unethical behavior (EM). In addition, this paper supports the applicability of AAOIFI standards for IBs rather than the conventional standards such as IFRS or local GAAP. Originality/value To the best of the authors’ knowledge, the findings are unique at two levels. First, the paper provides evidence on the economic consequences of using AAOIFI in the context of IBs which was not explored by previous research. Second, the paper extends the investigation of the impact of AAOIFI adoption for adopters verses non-adopters, as well as for mandatory verses voluntary adoption of AAOIFI.

This chapter presents eight historical accounts and stories of rabbis or a group of rabbis who served as third-party peacemakers in medieval and early-modern rabbinic literature. The chapter is divided into three subsections based on the status and degree of success of the third party. The first section focuses on successful third-party rabbinic peacemakers with high social status, the second on unsuccessful rabbinic peacemakers who possessed less social status, and the third explores exceptions to this assertion. The chapter also includes a discussion about the responsibility of the rabbi to serve as a peacemaker or mediator in Jewish law and tradition.

SUMMARYUnrelated and initially unfamiliar male CFLP mice, maintained for different periods in groups of 6, differed in both their rate of clearance of Babesia microti and the time taken to reach peak parasitaemia in relation to their aggressive behaviour within groups prior to infection. Males maintained in groups for shorter periods and showing more aggression within their group were slower to clear infection and males showing more marked external evidence of aggressive interaction reached a peak of parasitaemia sooner. Serum IgG and corticosterone analyses were consistent with increased aggression causing stress-induced immunodepression but relationships with aggression and social status were not simple. Males showing more aggression tended to enter their groups with higher levels of corticosterone and, to a lesser extent, reduced levels of IgG compared with other mice. The results thus suggest that increased susceptibility to disease may be a cost to males aggressively maintaining high social status.

The article considers the impact of the COVID-19 pandemic on living standards in Ukraine and countries around the world. The status of the indicators of labor market development and the macro-economic indicators reflecting the standard of living of the population are evaluated. Negative tendencies of changes in unemployment rate during 2013–2020 and its exacerbation during the COVID-19 pandemic are determined. The authors analyzed changes in GDP levels in Ukraine and in Central and Eastern Europe, trends in the decline in the real wage index in Ukraine are highlighted. It is noted that the COVID-19 pandemic and quarantine restrictions have led to significant socio-economic consequences that have negatively affected the standard of living of the population of Ukraine. This is evidenced by the growth of unemployment of the population and a decrease in the level of real wages, the deterioration of macro-economic indicators, in particular gross domestic product. In order to increase the standard of living of the population in the context of the COVID-19 pandemic, measures have been identified that include: enhancing the amount of financial support for small and medium-sized businesses, providing tax benefits to enterprises that employ graduates of educational institutions; raising minimum social standards taking into account their corresponding level in the EU countries; development and implementation of the State-based social programs aimed at supporting socially vulnerable categories of the population in the context of the COVID-19 pandemic; improving the investment climate and attracting investments to the real sector of the economy; stimulating the development of youth entrepreneurship, introducing dual education, forming an effective dialogue in the spheres of education and business; use of reserves for the introduction of innovative forms of employment and self-employment of the population (freelance, part-time work, etc.).

Space Lab 3 (SL-3) was flown on Shuttle Challenger providing an opportunity to measure the effect of spaceflight on rat testes. Cannon developed the idea that organisms react to unfavorable conditions with highly integrated metabolic activities. Selye summarized the manifestations of physiological response to nonspecific stress and he pointed out that atrophy of the gonads always occurred. Many papers have been published showing the effects of social interaction, crowding, peck order and confinement. Flickinger showed delayed testicular development in subordinate roosters influenced by group numbers, social rank and social status. Christian reported increasing population size in mice resulted in adrenal hypertrophy, inhibition of reproductive maturation and loss of reproductive function in adults. Sex organ weights also declined. Two male dogs were flown on Cosmos 110 for 22 days. Fedorova reported an increase of 30 to 70% atypical spermatozoa consisting of tail curling and/or the absence of a tail.

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.
