Behavioral repertoire of the Brazilian spiny-rats, Trinomys setosus and Clyomys laticeps: different levels of sociality

Behavior is a useful trait for comparative studies that provide the comprehension of phylogenetic relationships among species. Here, we present a description of two spiny-rats species’ behavioral repertoire, Clyomys laticeps and Trinomys setosus (Rodentia: Echimyidae). The affiliative and agonistic behavioral patterns were sampled during a three-year study of captive populations of wild animals. Observational data were collected in two phases under different arrangements of individuals in groups. We also compare the behavioral traits of T. setosus and C. laticeps with the known behavioral patterns of Trinomys yonenagae. We add categories to the previous descriptions of T. setosus and a standard ethogram for C. laticeps. Trinomys setosus showed a visual and vocal display we called foot-trembling, which was not described in this form and function for other species studied until now. We discuss the differences in their sociality levels and similarities and differences among behavior patterns and repertoires.

Assessing Sexual Behavior Patterns among Student Athletes of Senior High Schools in the Upper East Region, Ghana

The purpose of this study was to investigate the sexual behavior patterns of student athletes of senior high schools in the Upper East Region of Ghana and to assess the differences in sexual behavior patterns between male and females. A sample of 400 student athletes using a convenience sampling technique from public senior high schools was drawn to complete a self-designed research study. Descriptive statistics and the Chi-square test tool were used to analyze the collected data. The results showed that student athletes practiced various forms of sexual behaviors such as celibacy, foreplay, vaginal-penile sex, sexual fantasy, masturbation, oral sex, and anal sex. The Chi-square analysis showed significant gender differences in prevalence of masturbation (χ2 (1, n = 400) = 4.6962, probability = 0.030) and sexual fantasy (χ2 (1, n = 400) = 6.8477, probability = 0.009), but not vaginal-penile intercourse (χ2 (1, n = 400) = 1.3197, probability = 0.251) and celibacy (χ2, (1, n = 400) = 0.0721, probability = 0.788). The study concludes that student athletes of senior high schools might be vulnerable to unplanned parenthood and are at risk of STIs, including HIV. Regular health promotion campaigns on sexual risk-taking behaviors are required to help reduce the prevalence of student athletes’ indulgence in risky sexual behavior patterns that can harm their health. It is essential to implement gender-specific interventions (e.g., decision-making skills) when addressing the problems of sexual behaviors among the student athletes in the region.

The pattern of play behaviors in white-headed langurs from 1 to 12 months old in limestone forests, southwest China

Play behavior is a significant trait of immature nonhuman primates (hereafter primates), which may play important roles in sensory, locomotor, socio-cognitive, and developmental processes in primates. It has been suggested that function of play is to practice and improve motor skills related to foraging, avoiding predation, attracting mates, raising offspring, and also is to strength social skills concerning to cementing friendly relationships and defraying aggression among individuals. From September 2009 to August 2010, we investigated play behaviors of 1-12-month-old white-headed langur (Trachypithecus leucocephalus) which is a critically endangered primate endemic to China. During this study, we recorded 4,421 play bouts and 1,302 minutes of play time of 7 infants in total. We found that infants had different play behavior patterns at different ages. Specifically, non-social play behaviors appeared at 1 month of age, social play behaviors at 2 months, and all types of social and non-social play behaviors at 3 months. The frequency and duration of non-social play peaked at 5 months and then decreased, while social play appeared at 2 months and gradually increased with age. Non-social play did not differ between the sexes, whereas social play showed sex specificity, with higher frequency and duration of social play in male infants than in female infants. In addition, male and female white-headed langur infants appeared to prefer the individuals of same sex as social playmates. In conclusion, we first reported the pattern of play behavior of a critically endangered langur aged 1 to 12 months though the sample size is small, our results suggest they may have the adaptation of play behaviors in ages and sexes, which may help them adapt to their habitat and social system.

Delta T, a Useful Indicator for Pharmacy Dispensing Data to Monitor Medication Adherence

Introduction: Calculating patients’ medication availability from dispensing or refill data is a common method to estimate adherence. The most often used measures, such as the medication possession ratio (MPR), average medication supplies over an arbitrary period. Averaging masks the variability of refill behavior over time. Goal: To derive a new absolute adherence estimate from dispensing data. Method: Dispensing histories of patients with 19 refills of direct oral anticoagulants (DOAC) between 1 January 2008 and 31 December 2017 were extracted from 39 community pharmacies in Switzerland. The difference between the calculated and effective refill day (ΔT) was determined for each refill event. We graphed ΔT and its dichotomized version (dΔT) against the MPR, calculated mean ΔT and mean dΔT per refill, and applied cluster analysis. Results: We characterized 2204 refill events from 116 DOAC patients. MPR was high (0.975 ± 0.129) and showed a positive correlation with mean ΔT. Refills occurred on average 17.8 ± 27.9 days “too early”, with a mean of 75.8 ± 20.2 refills being “on time”. Four refill behavior patterns were identified including constant gaps within or at the end of the observation period, which were critical. Conclusion: We introduce a new absolute adherence estimate ΔT that characterizes every refill event and shows that the refill behavior of DOAC patients is dynamic.

The Social

The social is constituted by on-going communication and behavior patterns that influence participants perceptions, expectations and moral boundaries. For some, moral boundaries protect the racial hierarchy of American prosperity by calling natural what is actually social. Controversary about the meaning of sex, race, and ancestry can help us understand this difference, and thereby sharpen our awareness of our experiences of the social from social diversity to social amnesia. Social amnesia eliminates any awareness of the climate of injustice. In this context, a disturbing trend is our increasing reliance on private philanthropy to solve social problems, which moves us toward a new form of feudalism instead of a civic democracy. In a civic space that arises from the connections between our shared humanity and social differences, it is possible to listen to diverse voices and to make incoherent stories coherent.

Self-efficacy and behavior patterns of learners using a real-time collaboration system developed for group programming

In order to promote the practice of co-creation, a real-time collaboration (RTC) version of the popular block-based programming (BBP) learning environment, MIT App Inventor (MAI), was proposed and implemented. RTC overcomes challenges related to non-collocated group work, thus lowering barriers to cross-region and multi-user collaborative software development. An empirical study probed into the differential impact on self-efficacy and collaborative behavior of learners in the environment depending upon their disciplinary background. The study serves as an example of the use of learning analytics to explore the frequent behavior patterns of adult learners, in this case specifically while performing BBP in MAI integrated with RTC. This study compares behavior patterns that are collaborative or individual that occurred on the platform, and investigates the effects of collaboration on learners working within the RTC depending on whether they were CS-majors or not. We highlight advantages of the new MAI design during multi-user programming in the online RTC based on the connections between the interface design and BBP as illustrated by two significant behavior patterns found in this instructional experiment. First, the multi-user programming in the RTC allowed multiple tasks to happen at the same time, which promoted engagement in joint behavior. For example, one user arranged components in the interface design while another dragged blocks to complete the program. Second, this study confirmed that the Computer Programming Self-Efficacy (CPSE) was similar for individual and multi-user programming overall. The CPSE of the homogeneous CS-major groups engaged in programming within the RTC was higher than that of the homogeneous non-CS-major groups and heterogeneous groups. There was no significant difference between the CPSE of the homogenous non-CS group and the CPSE of the heterogeneous groups, regardless of whether they were engaged in individual programming or collaborative programming within their groups. The results of the study support the value of engaging with MAI collaboratively, especially for CS-majors, and suggest directions for future work in RTC design.
