In this paper, we demonstrate that, in a context where peer groups do not overlap fully, it is possible to identify all the relevant parameters of the standard linear-in-means model of social interactions. We apply this novel identification structure to study peer effects in the choice of college major. Results show that one is more likely to choose a major when many of her peers make the same choice. We also show that peers can divert students from majors in which they have a relative ability advantage, with adverse consequences on academic performance, entry wages, and job satisfaction.

I study the relative academic performance of students tracked or randomly assigned to South African university dormitories. Tracking reduces low-scoring students' GPAs and has little effect on high-scoring students, leading to lower and more dispersed GPAs. I also directly estimate peer effects using random variation in peer groups across dormitories. Living with higher-scoring peers raises students' GPAs, particularly for low-scoring students, and peer effects are stronger between socially proximate students. This shows that much of the treatment effect of tracking is attributable to peer effects. These results present a cautionary note about sorting students into academically homogeneous classrooms or neighborhoods. (JEL I23, I24, I28, O15, Z13)

The COVID-19 pandemic is affecting the mental health of employees. Deterioration of the well-being of workers is also caused by changes in the working environment. Remote working can affect both social interactions and job satisfaction. The purpose of the study is to examine what factors influence job satisfaction in the context of remote work caused by a pandemic. The study analyses whether employee relations and interpersonal trust are related to the level of perceived job satisfaction. The investigation started with a literature review and then research hypotheses have been formulated. Based on an empirical study, carried out on a sample of 220 IT employees during the pandemic, an analysis of the mediating role of trust in links between employee relations and perceived job satisfaction was conducted. The current study found that positive employee relations contribute to the level of job satisfaction. Additionally, trust is an important factor that mediates these relationships. Based on the results of the research, it was possible to describe the mechanism of shaping a supportive work environment during a pandemic.

Existing evidence on peer effects in the productivity of coworkers stems from either laboratory experiments or real-world studies referring to a specific firm or occupation. In this paper, we aim at providing more generalizable results by investigating a large local labor market, with a focus on peer effects in wages rather than productivity. Our estimation strategy—which links the average permanent productivity of workers' peers to their wages—circumvents the reflection problem and accounts for endogenous sorting of workers into peer groups and firms. On average over all occupations, and in the type of high-skilled occupations investigated in studies on knowledge spillover, we find only small peer effects in wages. In the type of low-skilled occupations analyzed in extant studies on social pressure, in contrast, we find larger peer effects, about one-half the size of those identified in similar studies on productivity.

<p>This research assessed the social interaction and the academic performance of the deaf and hard of hearing students in a school for the deaf in Cebu City, Philippines. There were 49 respondents who were assessed in terms of their social interaction and academic performance. A survey questionnaire was used to assess the level of their social interaction and their grades were used to measure their academic performance. Data gathered were treated statistically using descriptive and inferential statistics. Results showed that the respondents had an average age of 19.5 years old that are deaf with 3 to 4 siblings. The respondents had high social interaction with their teachers and peers but had moderate social interaction with their family members and very low social interaction with the hearing students. They perform satisfactorily in school. There were significant relationships between their interaction with their family members and the hearing students. Thus, school administrators are encouraged to design programs that would improve the social interactions of the deaf and hard of hearing students within the school community and at home. </p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0970/a.php" alt="Hit counter" /></p>

ObjectiveDiscuss neurorehabilitation efficacy in a case of concussion without direct head impact.BackgroundWhile there is growing concern about the prevalence and severity of concussion in mixed martial arts, a grappling component, Brazilian Jiu-Jitsu, is not typically perceived as high risk. Rapid acceleration or deceleration without direct head trauma led to a concussion for a 15-year-old male during jiu-jitsu throwing drills. The subject and parents reported difficulty with academic performance, social interactions, and emotional regulation. Symptoms persisted for 4 months before care was sought by the subject and his parents. Without direct head trauma or impact, concussion was not initially suspected.Design/MethodsThirteen sessions of treatment were performed in a neurorehabilitation setting utilizing joint manipulation, vestibular rehabilitation with a whole-body off-axis rotation device, oculomotor exercises, neuromuscular re-education, and electrical stimulation. C3 Logix was utilized as a baseline (immediately preceding second treatment due to equipment difficulties) and at discharge to measure effects of treatment.ResultsData is reported as “(baseline, discharge, percent-change).” Graded Symptom Checklist score out of 162 (91, 20; −78.02%), Trail Making Test A (sec) (26.8, 19.7; −26.49%), Trail Making Test B (sec) (69.9, 37.9; −45.78%), Digit-Symbol Matching speed (# of symbols) (66, 71; +7.58%), Choice reaction time (msec) (452, 397; −12.17), Static:Dynamic Visual Acuity (line difference) (1, 0.4; −60%). Subjectively, the subject and his parents reported improved academic performance, social interactions, and emotional regulation leading to a better home and educational experience for all involved.ConclusionsThis case displays positive clinical improvements with a functional neurology approach to outpatient neurorehabilitation. Further investigation into this multimodal rehabilitation for post-concussion symptoms, with and without direct head impact, is recommended. Continued concussion education and awareness are recommended for sports with rapid acceleration or deceleration and limited direct head impact.

We explore how herd composition and management factors correlate with frequencies of social interactions in horse groups. Since the welfare of horses correlates with low aggression levels and social contact opportunities, information of this kind is important. The data are a collection of records of social interactions of 426 Icelandic horses in 20 groups of at least eight horses. The complexities and limitations of the data prohibit useful statistical modelling so the results are presented descriptively. Interesting and informative patterns emerge which can be of use both in management and in future studies. Of special interest are the low levels of agonistic behaviours in breeding groups where one stallion was present. The horses were less agonistic when in groups with young foals and where group membership was stable. Unfamiliar yearlings in peer groups were especially aggressive. Allogrooming was most frequent in groups with relatively more young horses and in unstable and small groups. Interestingly, the horses allogroomed more if they had few preferred allogrooming partners. The findings show that composition (age/sex) and stability of groups are of great importance with respect to aggression levels and opportunities for establishing bonds.
