Probability Learning: Changes in Behavior Across Time and Development

Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience—within a learning session and over development—influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4–11 years) and adults searched for rewards hidden in locations with predetermined probabilities. In Experiment 1, children (n = 42) and adults (n = 32) changed strategies to maximize reward receipt over time. However, adults demonstrated greater strategy change efficiency. Making the predetermined probabilities more difficult to learn (Experiment 2) delayed effective strategy change for children (n = 39) and adults (n = 33). Taken together, these data characterize how children and adults alike react flexibly and change behavior according to incoming information.     

Wellness of Minority Female Counselor Educators

Minority female counselor educators are faced with numerous challenges. This qualitative study revealed that for female minority counselor educators, these challenges continue to negatively affect their professional and personal experiences. It is through operational wellness practices and optimal balance and functioning that minority female counselor educators have often prevailed. Implications for minority female counselor educators, university administrators, and counselor educators from the majority population are provided.     

A functional agility short-term fatigue protocol changes lower extremity mechanics

The purpose of this study was to evaluate the effects of a functional agility fatigue protocol on lower extremity biomechanics between two unanticipated tasks (stop-jump and sidestep). The subjects consisted of fifteen female collegiate soccer athletes (19±0.7 years, 1.67±0.1 m, 61.7±8 kg) free of lower extremity injury. Participants performed five trials of stop-jump and sidestep tasks. A functional short-term agility protocol was performed, and immediately following participants repeated the unanticipated running tasks. Lower extremity kinematic and kinetic values were obtained pre and post fatigue. Repeated measures analyses of variance were conducted for each dependent variable with an alpha level set at 0.05. Knee position post-fatigue had increased knee internal rotation (11.4±7.5° vs. 7.9±6.5° p=0.011) than pre-fatigue, and a decreased knee flexion angle (-36.6±6.2° vs. ?40.0±6.3°, p = 0.003), as well as hip position post-fatigue had decreased hip flexion angle (35.5±8.7° vs. 43.2±9.5°, p = 0.002). A quick functional fatigue protocol altered lower extremity mechanics of Division I collegiate soccer athletes during landing tasks. Proper mechanics should be emphasized from the beginning of practice/game to aid in potentially minimizing the effects of fatigue in lower extremity mechanics.     

Apprentice or Student? The Structures of Construction Industry Vocational Education and Training in Denmark and Sweden and their Possible Consequences for Safety Learning

There is a notable difference in occupational injury rates in the two Scandinavian countries, Sweden and Denmark, with the latter having a 40% higher rate of fatal occupational injuries in the construction industry. This study explored differences in the vocational education and training (VET) systems between Sweden and Denmark that may be important for students’ safety learning and practice during VET. In both countries, students participate in full-time education, and the curriculum includes school-based as well as company- based training. However, during company- based training Swedish students retain their student status, whereas Danish students are employed as apprentices. From a perspective of viewing safety as a social practice developed through interactions of different social and institutional bodies, the analysis points to this difference in employment status as important for their safety practices and also for the teachers’ position to influence safety learning and practices during company-based training. An analysis of interview and survey data focusing on how VET students enact safety ‘knowings’ across learning sites, suggest how different forms of connectivity models in VET promote various forms of safety learning among students.     

The mutant journal: how adaptations to online forces are forcing STM journals to mutate

Journals treat information in a peculiar manner. Now, online publishing is forcing rapid mutation of the journal's inherently volatile genetic code. This paper proposes a sequence of mutation, and discusses the evolutionary forces at work and how publishers can themselves adapt when faced with mutant journals.
