Abstract Visual observations of social behavior and dominance relationships in cattle have been used to examine associations with productivity and well-being. This method is time consuming limiting the number of animals that can be evaluated. The objective of this study was to validate an algorithm to quantify feedbunk replacement events using data from an electronic feeding system. Crossbred beef steers (n = 20) fed a grower diet were housed in 1 of 2 pens each equipped with 3 electronic feedbunks (GrowSafe Systems) and video recorders. A trained video observer recorded all feedbunk replacement events and other agonistic activities at the feedbunk over a 4-d period (24 h/d). The electronic feeding system recorded the start and end timestamps of bunk visit (BV) events for each animal. An algorithm was developed to determine BV events deemed to be replacement events, defined as a BV event when an actor animal displaced a reactor animal from the feedbunk and occupied the same feeder within a specified period of time (replacement criterion). We calculated the recall and precision corresponding to replacement criterions from 1 to 60 s, and the optimum replacement criterion was determined to be between 18 and 20 s. The recall, precision and F-score of the algorithm using this replacement criterion were high (on average > 0.75). Furthermore, a replacement competition index was computed as a proxy for competitive feedbunk behavior, calculated as the number of actor-initiated replacement events divided by the total number of replacement events for each steer. Using Spearmans rank correlation we found high correlations (r > 0.7; P < 0.05) between the electronic and observed indices. These preliminary results demonstrate the potential of the GrowSafe system to quantify feedbunk replacement events for confined beef cattle, providing opportunities to evaluate associations between competitive feedbunk behavior and economically relevant traits.

Background: Nursing educators should train nursing students to pursue physical, psychological, spiritual, and social health promotion. The purpose of this study was to explore relationships between nursing students’ meaning of life, positive beliefs, and well-being. Methods: A cross-sectional correlational study with a quantitative approach was adopted. Purposive sampling was used. A total of 170 nursing students voluntarily participated in this study. A 56-item questionnaire was used to examine nursing students’ meaning of life (1-25 items), positive beliefs (1-11 items), and well-being (1-20 items). The content validity index (CVI) of the study questionnaire was established as 0.95 by seven expert scholars. The reliability values for the three parts of the measure were as follows: meaning of life, Cronbach’s α 0.96; positive beliefs, Cronbach’s α 0.93; and well-being, Cronbach’s α 0.95. Percentages, frequencies, means, SDs, Kruskal-Wallis one-way analysis of variance by rank, Spearman’s rank correlation, one-way analysis of variance, Spearman’s rho correlation, and regression analysis were used for the data analysis. Results: Nursing students had the following mean scores: meaning of life with 4.02 (SD 0.56); positive beliefs with 3.92 (SD 0.62); and well-being with 3.95 (SD 0.57). The results indicate that for all nursing students, meaning of life was positively correlated with positive beliefs, r=0.83 (P<.01); similarly, all nursing students had positive beliefs that were positively correlated with meaning of life, r=0.83 (P<.01). In the results of the study, the nursing students’ background, meaning of life and positive beliefs explained 63% of the variance in well-being (Adjusted R2 squared =0.63, F=33.41, P<.001). Conclusions: Nursing students’ sense of meaning of life and positive beliefs may impact their well-being. Therefore, nursing educators can promote meaning of life and positive beliefs to nursing students as a way to increase their well-being for physical, psychological, spiritual, and social health promotion.

The Impact

ABSTRACT Shade is a mechanism to reduce heat load providing cattle with an environment supportive of their welfare needs. Although heat stress has been extensively reviewed, researched, and addressed in dairy production systems, it has not been investigated in the same manner in the beef cattle supply chain. Like all animals, beef cattle are susceptible to heat stress if they are unable to dissipate heat during times of elevated ambient temperatures. There are many factors that impact heat stress susceptibility in beef cattle throughout the different supply chain sectors, many of which relate to the production system, i.e. availability of shade, microclimate of environment, and nutrition management. The results from studies evaluating the effects of shade on production and welfare are difficult to compare due to variation in structural design, construction materials used, height, shape, and area of shade provided. Additionally, depending on operation location, shade may or may not be beneficial during all times of the year, which can influence the decision to make shade a permanent part of management systems. Shade has been shown to lessen the physiologic response of cattle to heat stress. Shaded cattle exhibit lower respiration rates, body temperatures, and panting scores compared to un-shaded cattle in weather that increases the risk of heat stress. Results from studies investigating the provision of shade indicate that cattle seek shade in hot weather. The impact of shade on behavioral patterns is inconsistent in the current body of research, some studies indicating shade provision impacts behavior and other studies reporting no difference between shaded and un-shaded groups. Analysis of performance and carcass characteristics across feedlot studies demonstrated that shaded cattle had increased ADG, improved feed efficiency, HCW, and dressing percentage when compared to cattle without shade. Despite the documented benefits of shade, current industry statistics, although severely limited in scope, indicate low shade implementation rates in feedlots and data in other supply chain sectors do not exist. Industry guidelines and third party on-farm certification programs articulate the critical need for protection from extreme weather but are not consistent in providing specific recommendations and requirements. Future efforts should include: updated economic analyses of cost versus benefit of shade implementation, exploration of producer perspectives and needs relative to shade, consideration of shade impacts in the cow-calf and slaughter plant segments of the supply chain, and integration of indicators of affective (mental) state and preference in research studies to enhance the holistic assessment of cattle welfare.

Abstract Background Students who are subjected to sexual harassment at school report lower psychological well-being than those who are not exposed. Yet, it is possible that the occurrence of sexual harassment in the school class is stressful also for those who are not directly targeted, with potential negative effects on well-being for all students. The aim was to examine whether sexual harassment at the student- and at the class-level was associated with students' psychological complaints. Methods Data from the Swedish Health Behaviour in School-aged Children (HBSC) of 2017/18 was used, with information from students aged 11, 13 and 15 years (n = 3,720 distributed across 209 classes). Psychological complaints were constructed as a summative index of four items capturing how often the student had felt low, felt irritable or bad tempered, felt nervous, or had difficulties to fall asleep, during the past six months (Cronbach's alpha=0.78). Sexual harassment at the student-level was measured by one item concerning bullying at school: “Other students have exposed me to sexual jokes”. Students who reported that this had happened at least “2 or 3 times a month” were classified as exposed to sexual harassment at school. Sexual harassment at the class-level was defined as the school class proportion of students exposed to sexual harassment, reported in per cent. Two-level linear regression analysis was applied. Results Students who had been exposed to sexual harassment had higher levels of psychological complaints (b = 2.74, p &lt; 0.001). The proportion of students in the school class who had been exposed to sexual harassment was also associated with higher levels of psychological complaints, even when adjusting for sexual harassment at the student-level, gender and grade (b = 0.03, p = 0.015). Conclusions Sexual harassment is harmful for those who are exposed, but may also affect other students negatively. Thus, a school climate free from sexual harassment will profit all students. Key messages Using data collected among students aged 11, 13 and 15 years, this study showed that sexual harassment at the student- and class-level was associated with higher levels of psychological complaints. Sexual harassment is harmful for those who are exposed, but may also affect other students negatively. Thus, a school climate free from sexual harassment will profit all students.

Abstract Background It is believed that clients with psychological trauma experiences have a poor prognosis with regard to treatment participation and outcomes for substance use disorders. However, knowledge on the effect of the number of trauma experiences is scarce. Methods Using data from drug use disorder (DUD) treatment in Denmark, we assessed the impact of having experienced multiple potentially traumatic experiences on DUD treatment efficacy. Baseline and follow-up data from 775 young participants (mean age = 20.2 years, standard deviation = 2.6) recruited at nine treatment centers were included in analyses. Results Analyses showed that participants who were exposed multiple trauma experiences also reported a significantly higher intake of cannabis at treatment entry, and a lower well-being score than participants who reported less types or no types of victimization experiences. During treatment, patients with multiple types of trauma experiences showed a slower rate of reduction of cannabis than patients with few or no trauma experiences. The number of trauma types was not associated with number of sessions attended or the development of well-being in treatment. Conclusion Overall, the results show that although traumatized youth in DUD treatment show up for treatment, helping them to reduce substance use during treatment is uniquely challenging.

Health And Well Being

Social distancing and isolation measures in response to COVID-19 have confined individuals to their homes and produced unexpected side-effects and secondary risks. In Latin America, the measures taken by individual governments to mitigate these new daily and experiential risks have varied significantly as have the responses to social isolation in each country. Given these new social circumstances, the purpose of this article is to investigate, from the sociological approach of risk-taking, the relationship between confinement, secondary risks and social inequality. The author argues that secondary risks, despite their broad scope, are deeply structured by social inequalities in contemporary societies, especially in developing countries. To corroborate this hypothesis, a quantitative comparative analysis is performed for the Argentine case. Using data from a web-survey and correspondence analysis (CA), there are three major findings: (1) there are some widespread experiences similarly distributed across all social strata, especially those related to emotional and subjective matters; (2) other risks follow socio-structural inequalities, especially those corresponding to material and cultural aspects of consumption; (3) for specific vulnerable groups, compulsory confinement causes great dilemmas of decision-making between health and well-being.

AbstractEpidemic control measures that aim to introduce social distancing help to decelerate the spread of the COVID-19 pandemic. However, their consequences in terms of mental well-being might be negative, especially for older adults. While existing studies mainly focus on the time during the first lockdown, we look at the weeks afterward in order to measure the medium-term consequences of the first wave of the pandemic. Using data from the SHARE Corona Survey, we include retired respondents aged 60 and above from 25 European countries plus Israel. Combining SHARE data with macro-data from the Oxford COVID-19 Government Response Tracker allows us to include macro-indicators at the country level, namely the number of deaths per 100,000 and the number of days with stringent epidemic control measures, in addition to individual characteristics. The findings show that both macro-indicators are influential for increased feelings of sadness/depression, but that individual factors are crucial for explaining increased feelings of loneliness in the time after the first lockdown. Models with interaction terms reveal that the included macro-indicators have negative well-being consequences, particularly for the oldest survey participants. Additionally, the results reveal that especially those living alone had a higher risk for increased loneliness in the time after the first COVID-19 wave.

The Relationship

The lockdown, in the COVID-19 pandemic, is considered an external crisis that evokes innumerous changes in individuals lives. One of the changes is the work and family dynamics. Based on boundary theory we examine the mediated role of work and family balance and boundary segmentation behavior in the relationship between boundary violations and teleworkers’ stress and well-being. However, because women and men live their work and family differently, gender may condition the way teleworkers lead with boundary violations and boundary segmentation. Hypotheses were tested through moderated mediation modeling using data collected of 456 teleworkers during lockdown. In line with our expectations, teleworkers who have suffered most boundary violations were those with least boundary segmentation behaviors and with least work-family balance which, in turn was related to higher burnout and lower flourishing. Furthermore, gender was found to moderate the relationship between boundary violations from work-to-family and segmentation behavior in the same direction and this relationship was stronger for females than for males. We discuss implications for future research and for managing teleworkers, creating sustainability, both during a crise and stable days.

Abstract Adult children are at risk of emotional strain when parental caregiving needs emerge. Pearlin’s Stress Process Model (1990) and caregiver studies suggest minority caregivers report lower subjective caregiving burden, however, few studies simultaneously consider both the stresses and rewards of caregiving. Using data from Wave II of the Family Exchange Study (N = 243), we examine racial differences in midlife adults’ perceptions (i.e., stress and rewards) of assisting their parents with activities of daily living (ADLs) and the associations between perceptions of ADL assistance and emotional well-being among adults who help their parents with ADLs. Compared to non-minority caregivers (M = 4.18, SD = 0.91), minority caregivers (M = 4.45, SD = 0.84) found it more rewarding to help their mother (t(314) = -2.54, p &lt; .05), whereas non-minority caregivers (M = 2.25, SD = .1.27) found it more stressful to help their father than did minority caregivers (M = 1.64, SD = 0.99), t(162) = 3.01, p &lt; .01). After controlling for demographics and ADL needs, linear regression analyses revealed that the stress of helping parents predicted depression (F(6, 189) = 5.30, p &lt; .001) and race moderated the association (p &lt; .01); the association was only significant for minority caregivers (p &lt; .05). Implications will be discussed.

Abstract Social Integration has important implications for health and well-being during adulthood. Being socially integrated might be an important resource that helps people to regularly engage in daily positive events. With older age, this resource might become increasingly important. However, being well socially integrated might also mean that people are certain that they experience more positive events in the future and thus, respond with less positive affect to any given positive event. We examined perceived social integration as a predictor of engagement and responsiveness to positive events using data from the National Study of Daily Experiences 2. 1904 adults (Mean age = 56.25, min = 33, max = 84) reported their daily positive affect and daily positive events during 8 consecutive days of telephone interviews. Perceived social integration was assessed at baseline. Adults higher in social integration experienced daily positive events more frequently (b = 0.01, SE = 0.003, p &lt; .001), but showed less of an increase in positive affect on days with more-than-usual positive events (b = -0.003, SE = 0.001, p = .030). These models controlled for the Big Five personality traits, purpose in life, demographic variables and same-day occurrence of stressors. Age did not moderate the present associations. The present findings imply that social integration might be an important contributor to experiencing more positive events across adulthood. Being better socially integrated might also lead to responding with less positive emotions to any given positive event.

The article present results of the authors’ study of the social well-being of the Russian population – an assessment of the population’s health and attitudes towards a healthy lifestyle amid viral pandemic, based on materials of the Rosstat sample surveys of 2019 and 2020 and data from the All-Russian survey conducted by the Russian Public Opinion Research Center (VCIOM) on 27 September 2020. The authors described the transformation of living conditions in the light of the complex epidemiological situation and the increase in coronavirus cases among the population. Changes in the health status of the Russian population were analyzed by individual age groups.The article assesses the strength of the relationship between the social well-being of the population by selected socio-demographic groups and the period of self-isolation, quarantine, or other restrictions imposed during the coronavirus pandemic in 2020. To solve this problem, demographic and socio-economic characteristics of respondents are presented, the distribution of responses according to the survey results is estimated, and the most signifcant factor characteristics are selected. Respondent replies were grouped according to the selected questions, including in the territorial context (by federal districts). To determine the strength of the relationship between the respondents' answers to the question and their gender or age distribution, the coefcients of mutual conjugacy and rank correlation coefcients were calculated and analyzed.Analysis of the changes in the social well-being of population for 2019–2020 and the assessment of the strength of the relationship between the discussed indicators (gender, wealth, territory of residence) revealed the parameters that form the differences. After comparing the health status of the Russian population as a whole and by age groups in 2019 and 2020 based on data of sample survey on population health status, the following points were identifed. With the expected assessment of the population health status in the age distribution (deterioration in the older ages and better health in the younger ones), it also remains unchanged that more than half of the respondents characterize their health status as «very good» and «good». Noteworthy is the fact that the assessment of the health status of the Russian population has improved during the year. It is evidenced from changes in the structure of respondent replies, even though population health status survey of 2020 was conducted in the middle of lockdown amid the continuing negative trends in coronavirus morbidity and mortality.
