An application of the theory of the complex variable to the mapping of some potential functions.

Using the theory of the logarithmic potential and the methods of intersecting circles and radii, plots are obtained for the lines of flow and equipotentials for eight cases of two sources, two sinks, or a source and a sink of varying strengths. A detailed analysis of the equilibrium equipotentials is included. The problem of three unit sources placed at the vertices of an equilateral triangle is investigated; and the general expression of the equilibrium equipotential for n similar unit sources (or sinks) placed at the vertices of a regular n-sided polygon is developed.     

Wide Awake at 4 AM: A Study of Late Night User Behavior,Perceptions and Performance at an Academic Library

The expectation for extended library hours including 24 h access presents many questions about late night library users and the value of this service to the library and their corresponding institutions. Using data gathered about patrons who use the library after 11 pm and before 7 am, a study was conducted to discover who the library users were, what services and facilities they made use of, and what, if any, concerns they have regarding the late night library. The usage patterns provide evidence that that while more usage occurs during traditional hours, users who prefer late night do so consistently. The researchers found the late night library was serving patrons who were cross sections of university community with higher than average grade point averages and retention rates when compared to university averages. These figures can have a significant effect on institutional recruitment and retention presenting the library as an indispensable resource to the community.     

Gender differences among students undertaking iSTEM projects in multidisciplinary vs unidisciplinary STEM classrooms in government vs nongovermnment schools: Classroom emotional climate and attitudes

In response to the leaky STEM pipeline, particularly for girls, many schools have introduced integrated STEM (iSTEM) programs to enable students to solve problems using skills from each STEM area and hopefully enhance their interest in continuing with STEM subjects in senior-high school and university. We investigated whether gender differences in students’ perceptions of classroom emotional climate and attitudes to STEM depend on whether students are undertaking iSTEM projects as part of a multidisciplinary curriculum (S, T, E and M) or unidisciplinary curriculum (S, T, E or M) and also whether they attend a government or nongovernment coeducational school. The sample consisted of 256 students in 24 coeducational grade 7–9 classes in 8 government schools and 157 students in 12 coeducational grade 7–10 classes in 6 nongovernment schools. Whereas boys were significantly more positive than girls in perceptions of clarity, motivation, consolidation and attitudes to iSTEM in coeducational government schools, there were no significant gender differences in coeducational nongovernment schools. Students of both genders in government schools were significantly more positive about all aspects of classroom emotional climate and attitudes than students of both genders in nongovernment schools, even after controlling for socioeconomic status. Also, females were slightly more positive about classroom emotional climate and in their attitudes in multidisciplinary STEM classes in government schools. This study suggests that multidisciplinary STEM classes could motivate girls to pursue STEM subjects in senior-high school and at university.

     

Improving Communication Between Postgraduate Researchers and the University Library: A Case Study at De Montfort University Library and Learning Services

ABSTRACT

A well-established postgraduate researcher development program has existed at De Montfort University for many years. Library and Learning Services include modules on literature searching skills and critical appraisal. However, we recognized that researchers seemed to be disengaged with the services on offer. This concern informed a research project that considered the ways we could communicate better with researchers based on their needs. This paper explores the essential components of successful communication, such as context, timeliness and communication channels. An action-research approach was taken including focus groups and online surveys. The outcomes highlighted three significant crisis points, emphasizing the key times when researchers might need some intervention. The findings of this research identified the distinct needs of Postgraduate Researchers (PGRs) and how relevant and timely communication from the library can meet these needs. It also considers the impact of how communication has improved with researchers as a result of some of our interventions.     

Research Students in Education and Psychology: diversity and empowerment

ABSTRACT

Although some attention has been given in the literature to the notion of variable supervisor style, students are often discussed as if they are interchangeable and homogeneous. Results from this study of education and psychology departments in British universities suggest that there are several different ways to present oneself as a student, some more in continuity than others with the requisites for academic success. Five such ‘student styles’ are described and illustrated, and themes of diversity and empowerment are explored. Student styles can be seen as individual coping strategies, and the emphasis on individualism becomes part of the reproduction of the academic profession.     

Global undernutrition during gestation influences learning during adult life

Intrauterine growth restriction can lead to significant long-term health consequences such as metabolic and cardiovascular disorders, but less is known about its effects on choice and behavioral adaptation in later life. Virgin Wistar rats were time mated and randomly assigned to receive either ad-libitum access to chow or 30% of that level of nutrition during pregnancy to generate growth-restricted offspring. At 60 days of age, 6 female offspring from each group were trained on concurrent variable-interval schedules. Sessions consisted of seven randomly arranged concurrent-schedule components, each with a different reinforcer ratio that varied from 27:1 to 1:27, and each component lasting for 10 reinforcer deliveries. Behavioral change across reinforcers in components, measured by sensitivity to reinforcement, was consistently lower for offspring of undernourished mothers, showing that their behavior was less adaptable to environmental change. These results provide direct experimental evidence for a link between prenatal environmental conditions and reduced behavioral adaptability--learning--in later life.     

Relative‐change theory: examining the impact of patriarchy,paternalism, and poverty on the education of women in Kenya

Forty‐five years have passed since Kenya gained independence and almost 30 years since the feminist revolution ushered in a global gender and development agenda. While Kenya’s development agenda had a functionalist orientation aimed at modernisation, the outcome of efforts to promote education development cannot be understood without an examination of the context of women. Although development agencies acknowledge the need for empowerment of women, the interests of change agencies are accommodated within the bounds of patriarchy, poverty, and paternalism. This situation is best explained by examining the education experience of women through a relative‐change theory prism. From this perspective, change is actively pursued within limits, that is, options for change in the social, cultural, and political context are acknowledged but limited. As a result, whatever education development efforts have been put into place to benefit women in marginalised situations, the outcome has fallen short for the majority of women.
