Are You A Leader? How We Learned to Stop Asking

Smith College initiated an ePortfolio pilot project to guide students in documenting key learning experiences and in linking those experiences to Smith's institutional mission of “developing leaders for society's challenges” (Smith College, 2011 Smith College. 2011. Mission of Smith College. Retrieved from http://www.smith.edu/about_mission.php. [Google Scholar]). Twenty-one college students volunteered to participate in the pilot, based on the integrative knowledge portfolio process and informed by research in the fields of narrative psychology, integrative learning theory and ePortfolio theory. This article discusses the process of guiding students in integrative learning through the development of ePortfolios and through a curriculum, which engaged them in understanding and articulating their own learning, as well as in connecting it to the college mission.     

A Phenomenological Investigation of Counseling Doctoral Students Becoming Mothers

Women often face challenges when balancing academic and familial responsibilities (Gilbert, 2008 ; Trepal & Stinchfield, 2012 ). This phenomenological study explored women's (N = 10) experiences of becoming mothers during a doctoral program in counseling. The results highlight the importance of mentorship and other protective factors associated with a successful transition from student to mother.     

Motivational profiles as a combination of academic goals in higher education

The aim of the current study was to obtain information from students in higher education on different motivational profiles that resulted from the combination of three academic goals (i.e. learning goals (LG), performance-approach goals and performance-avoidance goals). Moreover, information related to the relevance of each goal within each motivational profile was explored to explain conditions closely related to the academic engagement. The sample consisted of 2556 students from five Spanish universities. Motivational profiles were obtained by using cluster analysis followed by a relevance analysis of each goal within each motivational profile. The results support the hypothesis concerning motivational profiles, and further suggest for motivational profiles with a predominance of LG to be more adaptive. According to our findings, high level of LG in one’s motivational profile appear to be a powerful protective factor in maintaining high interest in academic work, as well as high control beliefs and self-efficacy.     

Models and messengers of resilience: a theoretical model of college students’ resilience,regulatory strategy use,and academic achievement

We tested a theoretical model of college students’ ratings of messengers of resilience and models of resilience, students’ own perceived resilience, regulatory strategy use and achievement. A total of 116 undergraduates participated in this study. The results of a path analysis indicated that ratings of models of resilience had a direct effect on students’ perceived resilience and that perceived resilience directly influenced regulatory strategy use (i.e. effort regulation, self-regulation and time management), which influenced academic achievement (as measured by grade point average). The implications of our findings are further discussed, along with avenues for future research.     

Youthful Ideals of Older Adults: An Analysis of Children's Drawings

Over the years, disparities have continued to emerge about what factors influence children's views of older adults. The purpose of this study was to gain further understanding regarding youthful ideals of aging through an analysis of children's drawings. After completing their drawings, the children were interviewed to provide a better understanding and to give clarity of the drawn images. The sample included 141 children ages 8–12 from different Boys and Girls Clubs of America across the United States. Overall, the children produced a generally positive image (84.8%) with most drawing a family member who was happy, healthy, active, and with positive physical characteristics. Significant differences were found between the genders as the girls drew more positive images than the boys; however, no significant differences existed between children from different races and ages.     

‘Well I don't feel that’: Schemas,worlds and authentic reading in the classroom

This article explores reading in the English classroom through a cognitive linguistic lens. In particular, we consider how students' ability to engage with a text, which we term authentic reading, can be facilitated or restricted. We draw on two case studies featuring Year 7 students working with the novel Holes (Sachar 2000), and the short story ‘The man who shouted Teresa' (Calvino 1996) respectively, and argue for the benefits of using cognitive linguistics as a tool for teachers and researchers to ‘think with’ when considering reading in the classroom.     

Using Partial Least Squares (PLS) in Predicting Behavioral Intention for Telehealth Use among Filipino Elderly

Despite the potential benefits of Telehealth (healthcare delivery at a distance), a digital divide among seniors remains prevalent with lesser attention on their acceptance as end-users of technology. Anchored on a theory of technology adoption, Unified Theory of Acceptance and Use of Technology (UTAUT), behavioral intention for Telehealth use among Filipino elderly was determined. The responses of technology-trained older adults (n = 82) were collected using a 12-item questionnaire adapted from Venkatesh, Morris, Davis, Gordon, and Davis (2003) on UTAUT. A Structural Equation Modeling was performed using Partial Least Squares regression for data exploration and model estimation. The study revealed that the UTAUT constructs, particularly effort expectancy (ß = 0.319; p = .000), have yielded a significant influence on the behavioral intention of elderly to participate in Telehealth. Further, gender showed no moderating effect on these variables. Results of the study supported the espousal of UTAUT Model as an indispensable framework in empowering older adults using Telehealth.     

Lean mass as a total mediator of the influence of muscular fitness on bone health in schoolchildren: a mediation analysis

This report aims to analyse the independent association of lean mass and muscle fitness with bone mineral content (BMC) and bone mineral density (BMD), and to examine whether the relationship between muscle fitness and bone health is mediated by lean mass. Body composition (by dual energy X-ray absorptiometry (DXA)), muscle fitness, physical activity, age and height were measured in 132 schoolchildren (62 boys, aged 8–11 years). Analysis of covariance tested differences in bone-related variables by lean mass and muscle fitness, controlling for different sets of confounders. Linear regression models fitted for mediation analyses examined whether the association between muscle fitness and bone mass was mediated by lean mass. Children with good performance in handgrip and standing long jump had better and worse bone health, respectively. These differences disappeared after controlling for lean mass. Children with high lean mass had higher values in all bone-related variables. In addition, the relationship between muscle fitness and bone mass was fully mediated by lean mass. In conclusion, the relationship between upper-limbs muscle fitness and bone health seems to be dependent on lean mass but not on muscle fitness. Schoolchildren with high lean mass have more BMC and BMD in all regions. Lean mass mediates the association between muscle fitness and bone mass.     

Nonlinear Control of pressurized water reactors with uncertainties estimation via high order sliding mode

In this work, dynamic controllers are designed for reactor power, pressurizer water level, and pressure control in the primary circuit of a pressurized water reactor. These nonlinear controllers use super-twisting sliding-mode estimators to enhance their robustness versus parameter variations and external disturbances. Hence, the perturbative terms can be canceled by the control, thus improving the dynamic behavior of the controlled system. The designed controllers ensure good performances and better transient behavior, also in the presence of uncertainties and disturbances. A performance study of the proposed controllers is carried out in the presence also of unmodeled dynamics.     

Distributed data-driven UAV formation control via evolutionary games: Experimental results

This work proposes a novel data-driven distributed formation-control approach based on multi-population evolutionary games, which is structured in a leader-follower scheme. The methodology considers a time-varying communication graph that describes how the multiple agents share information to each other. We present stability guarantees for configurations given by time-varying interaction networks, making the proposed method suitable for real-world problems where communication constraints change along the time. Additionally, the proposed formation controller allows for an agent to leave or enter the group without the need to modify the behaviors of other agents in the group. This game-theoretical approach is evaluated through numerical simulations and real outdoors experimental results using a fleet of aerial autonomous vehicles, showing the control performance.
