Magnetic and transport properties of (Ba1-xKx)Fe2As2

Single crystals of (Bal - xKx)Fe2As2 were prepared using the Sn flux method. Two heating methods were used to prepare the single crystals: the slow heating and rapid heating methods. It was found that the single crystals grown using the slow heating method were not superconducting due to a significant loss of potassium. When the rapid heating method was used, the single crystals were observed to be superconducting with the desired potassium concentration. The energy dispersive X-ray spectroscopy analysis indicated the presence of multiple phases in the single crystals. Using single crystal X-ray diffraction, the crystal structure of the single crystals was found to be 14/mmm tetragonal at room temperature. The magnetic measurements on the single crystals indicated the presence of multiple phases and magnetic impurities.

Undergraduate Student Anxiety-Management in Academia: Appraising the Value of Services and Strategies

This study explored strategies that Brock University undergraduate students value the most for managing anxiety in academia. Although previous literature indicates services and techniques such as academic advising, physical activity, and educator engagement help students, few if any have ranked students’ perceived value of anxiety-management strategies. The researcher recruited 54 undergraduate student participants (primarily from the Department of Community Health Sciences) through online invitation. Participants completed an online survey to rate their previous experience with anxiety-management strategies discussed in the literature. Survey findings identified the 4 most valuable resources students used to manage anxiety in academia: (a) educators who post academic material posted online (e.g., on Sakai) early in the term, (b) physical activity, (c) socialization, and (d) breaking large assignments into smaller portions. Conversely, student participants found disability services, counseling, and medication to be the least valuable resources. Results suggest higher-education facilities should ensure that the most valuable services are readily available to students seeking them. The study contributes to the field by identifying a broad set of strategies that students find highly valuable in their management of academic related anxiety.

Using Network Analysis to Understand and Advance Falls Prevention Services and Programs

The purpose of this study was to understand referral linkages that exist among falls prevention agencies in a southern Ontario region using network analysis theory. This was a single case study which included fifteen individual interviews. The data was analyzed through the constant comparative approach. Ten themes emerged and are classified into internal and external factors. Themes associated with internal factors are: 1) health professionals initiating services; 2) communication strategies; 3) formal partnerships; 4) trust; 5) program awareness; and 6) referral policies. Themes associated with external factors are: 1) client characteristics; 2) primary and community care collaboration; 3) networking; and 4) funding. Recommendations to improve the referral pathway are: 1) electronic database; 2) electronic referral forms; 3) educating office staff; and 4) education days. This study outlined the benefit of using network analysis to understand referral pathways and the importance of implementing strategies that will improve falls prevention referral pathways.

Assessment of Stress During Handling and Transport

The article focuses on assessing the stress levels of animals when transported and handled. The paper was presented at a symposium titled Effects of Stress in Farm Animals at the American Society of Animal Science 87th annual meeting, July 1995.
