Cross Fostering

Abstract Cross-fostering is a common swine husbandry practice; however, little research has focused on the effects of foster stress on piglets post-weaning. This study evaluated the effect of cross-fostering on behavioral indicators of post-weaning stress susceptibility. Litters (n = 40) were allocated to 1 of 2 treatments: control (CON) and foster. Three piglets (FOS) from each CON litter were randomly selected and moved to a foster litter 12–24 h post-farrowing, where they were nursed along resident (RES) piglets until weaning (approximately 18 d of age). At 21- and 28-d post-weaning, a male and female piglet from each treatment (FOS, RES, CON) underwent 1 of 2 behavior tests: social isolation and social confrontation. Both tests were conducted in an isolated 1.22 × 1.22 m novel pen. For social isolation, escape attempts, movement between floor quadrants (i.e. locomotion), defecation, and urination events were counted. For social confrontation, the latency to first aggressive interaction and the number of aggressive interactions were quantified. All data were analyzed using the GLIMMIX procedure in SAS. The CON piglets moved between quadrants more frequently than RES piglets (P = 0.02), while FOS piglets moved between quadrants intermediate to (but not different from) CON and RES piglets (P = 0.44 and 0.12, respectively). Females moved between quadrants more frequently than males (P < 0.0001). The latency to first aggressive interaction was shorter in FOS piglets compared to CON piglets (P = 0.048). There was a treatment by sex interaction (P < 0.01) for number of aggressive interactions, with CON and RES females having more aggressive interactions than their male counterparts (P = 0.04 for both) while FOS females had fewer aggressive interactions than FOS males (P = 0.007). No additional differences were detected (all P > 0.05). Overall, these results provide little evidence that FOS piglets exhibit an increase in behavioral stress susceptibility post-weaning. However, future work should expand upon and clarify the social confrontation findings.

AbstractThe social dominance structure and aggressive patterns in a group of four male adult squirrel monkeys and four adolescent cebus monkeys were analyzed across different test conditions. The effects on frequency and direction of aggressive interaction as well as on social dominance structure were assessed after systematically varying the size of testing area, presence or absence of reinforcement, kind of reinforcement (food or shock), and after the monkeys in each established group were separated for two weeks. Under all test conditions, the squirrel monkey's social dominance structure consisted of a dominant boss monkey and an almost completely linear hierarchy for the group. The cebus monkey's social structure consisted of a dominant boss monkey and an almost nonlinear hierarchy for the group. The presence of reinforcement, kind of reinforcement, and size of testing area were shown to have important effects on frequency but not on the direction of aggressive interactions in both the mature squirrel monkey group and immature cebus monkey group.

This issue of the Brazilian Journal of Education, Technology and Society (BRAJETS) discusses the current context of the need for education mediated by technology. In times of exceptionality in which humanity finds itself due to the social isolation caused by the dissemination of Covid-19, it is very pertinent to deepen the theme “Teaching and learning mediated by technology”. Before only reflections were appropriate, now, more than ever, its application is imperative because, without the medium of technology, there is no way to continue academic practices. Thus, we bring some scientific contributions on this topic, which is very relevant nowadays through a set of 12 articles mostly related to the different spheres of education and teaching mediated by technology, involving both theoretical discussions and exploratory research. We invite all to enjoy a good reading of this issue, and that it can contribute with inspirations and ideas for writing and execution, whether of research or future work.

The Many

Three themes seem to be common to both Greenwood’s and Gustavsen’s accounts: One is the social isolation of professional [research] elites from the concerns of ordinary people, which connects with another: the privileging of theory over practice. Both of these are connected, however, with a third: the great, unresolved struggle of ordinary people to gain control over their own lives, to escape from schemes imposed on them by powerful elites, and to build a genuinely participatory culture. An understanding of Wittgenstein’s later philosophy, and the recognition of its striking differences from any previous philosophical works, can make some important contributions to all these issues. Wittgenstein’s aim is not, by the use of reason and argument, to establish any foundational principles to do with the nature of knowledge, perception, the structure of our world, scientific method, etc. Instead, he is concerned to inquire into the actual ways available to us of possibly making sense in the many different practical activities we share in our everyday lives together: “We are not seeking to discover anything entirely new, only what is already in plain view.”

Supervisor–subordinate work relationships are based on a series of potentially fluctuating resource allocation episodes. Building on this reality, we hypothesized in the present research that supervisor–subordinate work relationship quality will neutralize the negative attitudinal and behavioral strain effects associated with perceptions of others’ entitlement behavior. We draw upon the transactional theory of stress, and the social exchange and support features of leader–member exchange theory, to explain our expected neutralizing effects on job tension, job satisfaction, and contextual performance/citizenship behavior. Results supported study hypotheses in Sample 1. Findings were replicated in Sample 2 and extended by also demonstrating the interaction effect on task performance. Contributions to theory and research, strengths and limitations, directions for future work, and practical implications are discussed.

The Social

The social isolation due to the COVID-19 pandemic exerts lasing impacts on people’s mental health. However, whether and how people’s pre-existing positive social relationships can serve as stable reserves to alleviate people psychological distress following the disaster remains unknown. To address the question, the current study examined whether pre-pandemic relationship satisfaction would predict post-pandemic COVID-19 anxiety through middle-pandemic perceived social support and/or gratitude using four-wave data in China (N = 222, 54.50% female, Mage = 31.53, SD = 8.17). Results showed that people’s COVID-19 anxiety decreased from the peak to the trough pandemic stage; perceived social support increased markedly from the pre-pandemic to the peak and remained stable afterwards, while relationship satisfaction remained unchanged throughout. Further, it was middle-pandemic perceived social support, but not gratitude, mediated the association between pre-pandemic relationship satisfaction and post-pandemic COVID-19 anxiety, indicating perceived social support played a more crucial role than gratitude in this process. Last, it is suggested to distinguish perceived social support from gratitude as two different components of social interactions.

Sexual Dimorphisms

ABSTRACTIn many species, males possess specialized weaponry that have evolved to confer a benefit during aggressive interactions. Because male weaponry is typically an exaggerated or extreme version of pre-existing body parts, females often possess reduced or weaponry. Although much research has investigated sexual dimorphism in the sizes of such weapons, other weapon components, such as weapon performance or alternative weapon forms can also explain the evolution of weapon sexual dimorphisms. Here, we investigated the allometry and variation of multiple weapon components of hindleg weaponry in the male and female giant mesquite bugs, Thasus necalifornicus. Despite theory predicating greater allocation in male weaponry, we found that females allocated more into the lengths of their hindlegs compared to males. Despite this allocation, males possess relatively wider hindlegs, which likely increase area of muscle mass. Indeed, the squeezing performance of male hindlegs was much greater than that of female hindlegs. Lastly, we also described the allometry and variation in a male weapon component, prominent tibial spines, which likely are used to damage competitors during aggressive interaction. Overall, our findings highlight the intricacies of weapon sexual dimorphism and demonstrate the importance of measuring multiple weapon components and not a single measure.

The Autism Spectrum Disorder(ASD) are distinguished by persistent deficits in social communication and social interaction and restricted and repetitive patterns of behavior. Coronaviruses are an extremely common cause of colds and other upper respiratory infections. COVID-19, short for “coronavirus disease 2019”. The fast spread of the virus that causes COVID-19 has sparked alarm worldwide. The World Health Organization (WHO) has declared this rapidly spreading coronavirus outbreak a pandemic. Most of the countries around the world are adopting social distancing to slow the spread of coronavirus. There are several possible impacts of this pandemic on the daily lives of individuals with ASD, such as worsening of dysfunctional behaviors and regression of skills already acquired in different domains of development due to the social isolation. The objective of this article is to provide guidance to parents, health and education professionals that live or work with ASD individuals during the social isolation, on how to manage interventions that can be executed in the home environment, like remote training in language and social communication skills, behavioral strategies and sensory integration activities
