Demonstrator influence on observer diet preference: Analyses of critical social interactions and olfactory signals

Previous studies have shown that interaction of an observer rat with a previously fed conspecific demonstrator enhances the observer’s subsequent preference for the diet its demonstrator ate. The present series of experiments were undertaken to explore both the conditions sufficient to permit demonstrator influence on observer diet preference and the behavioral processes underlying such influence. We found (1) that an observer rat can be influenced in its subsequent diet selection by interaction for as little as 2 min with a demonstrator, (2) that during such brief interactions mouth-to-mouth contact between demonstrator and observer is necessary for demonstrator influence on observer diet preference, (3) that both cues emerging from the digestive tract of a rat fed by intragastric intubation and particles of food clinging to the fur of a demonstrator are sufficient to permit observers to identify their respective demonstrators’ diets, (4) that exposure to a diet is effective in enhancing an observer’s subsequent preference for that diet only if the diet is experienced in the presence of another rat, and (5) that diets experienced on the anterior of a live rat are more effective in altering observers’ subsequent diet preferences than the same diets experienced either on the anterior of a dead rat or the posterior of a live one.     

‘You’re 18 now,goodbye’: the experiences of young people with attention deficit hyperactivity disorder of the transition from child to adult services

The term ‘transition’ is used to refer to the process of moving from child to adult services. Among child and adolescent mental health services attenders, young people with Attention Deficit Hyperactivity Disorder (ADHD) are less likely to transition successfully, but there is a gap in understanding their views and why they might disengage from services. The aim of this study was to explore the experiences of transition of young people with ADHD in Southwest England using semi-structured interviews and thematic analysis. Seven young people aged 17–19 years participated. Four key themes were identified: professionals’ roles and relationships with young people; the role of ADHD medication, uncertainties around transition and medication management, and identified needs and increasing independence. Although this study presents the experiences of a small number of people, their stories suggest that best practice around transition is not always being followed. There is consequently a need to better understand the facilitators and barriers to best practice implementation.     

Can you increase teacher engagement with evaluation simply by improving the evaluation system?

We know various factors can influence how teaching staff engage with student evaluation, such as institutional policies or staff beliefs. However, little research has investigated the influence of the technical processes of an evaluation system. In this article, we present a case study of the effects of changing the technical system for administering student evaluations at one New Zealand university. We develop a socio-technical model of the institutional evaluation system, and use this model to examine whether introducing an online system for ordering student feedback questionnaires and reducing processing time influenced academic staff engagement with evaluation. Survey responses, interview comments and data about ordering trends suggest the change did increase staff engagement by: (1) improving staff perceptions of evaluation and (2) increasing engaged behaviour, such as voluntarily ordering more evaluations. The outcomes of this study imply that the ‘practical implementation’ of an evaluation system is an important factor in influencing engagement with evaluation. We conclude that we can increase teacher engagement with evaluation simply by improving the ‘practical implementation’ of the evaluation system.     

University intramural sport administrators' perceptions of gender modifications in intramural coed flag football

Coed sport environments can be paradoxical settings where pre-existing gender biases influence participants' enjoyment and success. Furthermore, gendered messages and stereotypes as well as low expectations for females within coed sports can create participation barriers by reducing feelings of confidence and performance. Within university intramural sport programs, administrators have a significant role in determining participation opportunities and experiences. From a critical perspective, this investigation examined administrators' perspectives about coed intramural flag football gender modifications. Specifically, four research questions guided this study: (1) How do intramural sport administrators view coed flag football gender modifications? (2) To what extent do intramural sport administrators perceive gender modifications to impact coed flag football environments? (3) What level of awareness do intramural sport administrators have about the gendered messages of coed flag football gender modifications? and (4) To what extent are intramural sport administrators willing to modify their perceptions of the rules in light of critical questioning? Qualitative interviews were used to obtain the perspectives of 12 intramural administrators from across the USA. Administrators reported that coed gender modifications impacted perceptions about female ability, often by sending messages of inequity. Moreover, administrators revealed that the modifications created competitive strategy that often diminished the integrity of the game and undermined perceptions of female ability. Findings also indicated that administrators were highly influenced by previously existing gender stereotypes, leading to an endorsement of the modifications. Endorsements were accompanied by questioning of the rules but reluctance to enact changes. These findings elucidate the importance of scrutinizing the existence and application of coed gender modifications. Furthermore, engaging flag football participant feedback on the specific attributes of the coed modifications is important to better understand the needs of female populations. Lastly, eliminating modifications may help diminish the gendered messages that currently exist within coed flag football.     

Simulation of gait asymmetry and energy transfer efficiency between unilateral and bilateral amputees

Efficient walking or running requires symmetrical gait. Gait symmetry is one of the key factors in efficient human dynamics, kinematics and kinetics. The desire of individuals with a lower-limb amputation to participate in sports has resulted in the development of energy-storing-and-returning (ESR) feet. This paper analyses a case study to show the effect of symmetry and asymmetry as well as energy transfer efficiency during periodic jumping between simulated bilateral and unilateral runners. A custom gait analysis system is developed as part of this project to track the motion of the body of a physically active subject during a set of predefined motions. Stance and aerial times are accurately measured using a high speed camera. Gait frequency, the level of symmetry and the non-uniform displacement between left and right foot and their effects on the position of the Centre of Mass (CM) were used as criteria to calculate both peak energies and transformation efficiency. Gait asymmetry and discrepancy of energy transfer efficiency between the intact foot and the ESR are observed. It is concluded that unilateral runners require excessive effort to compensate for lack of symmetry as well as asymmetry in energy transfer, causing fatigue which could be a reason why bilateral amputee runners using ESR feet have a superior advantage over unilateral amputees.     

How less is truly more: Merging library support services

ABSTRACT

In the summer of 2010, to provide a “one-stop shop” service point to Woodruff Library patrons, the Circulation, Reference, and Learning Commons (LC) desks merged into the unified Library Service Desk (LSD) under Access Services. Last year, due to organizational changes in the library and IT, and anticipated support needs of the new LC spaces and technologies, Student Digital Life opened a separate LC Technical Support desk. The lessons of the year of the two desks, funding considerations, and the persistent goal to streamline the experience of our patrons resulted in transitioning the functions of the LC desk to LSD, thus evolving it to new organizational and operational levels.     

A Case Study of a Turnaround High School: An Examination of the Maryland State Department of Education Breakthrough Center Intervention

This study examined the Maryland State Department of Education Breakthrough Center (BTC) engagement in a Baltimore City turnaround high school. Utilizing a case-study design and mixed-methods research, data were collected through interviews, informal observations, and review of administrative and achievement documents. Beginning in the 2011–2012 academic year, the BTC has been working in collaboration with school personnel to improve the educational experiences and academic achievement of students. School personnel recognized that the BTC has been responsive to teachers' requests and has exhibited a flexible approach building collaborative and nonevaluative relations. Administrative and achievement data also indicated improvement in school outcome measures during the past 3 years. Nevertheless, school faculty also identified important challenges of the BTC intervention, such as the relevance of this intervention for veteran teachers, the extent to which the needs of all student populations were met, and the sustainability of the intervention.
