Designing science laboratories: learning environments,school architecture and teaching and learning models

This article on secondary schools science laboratories in Portugal focuses on how school space functions as a pedagogical and political instrument by contributing to shape the conditions for teaching and learning dynamics. The article places the impact of changes to school layouts within the larger context of a public school renovation programme, discussing how school space functions as a pedagogical and political instrument. The focus is on science laboratories as a particular learning environment for science education. The study, conducted between 2010 and 2011 in 13 renovated schools within the framework of the Portuguese Secondary School Modernisation Programme, drew on document analysis, interviews, pupil and teacher surveys and site-specific focus groups. One of the main findings is that teachers found that science laboratories were the most controversial and debated of all the renovated learning spaces. Considering that the science laboratory layout was intended to be universal across all schools, there was little intervention by the architects responsible for the renovation of the schools. Focusing on the analysis of the decision to change the science laboratory design within the aims of the education policy, this article discusses how teachers’ criticisms were a response to some of the educational policy goals underlying the renovation of school buildings and the potential impact on science education, namely, the relationship between flexibility of space organisation and pedagogical approaches.     

Protective role of onion against acute alcoholic fatty liver

Rats were fasted for 8 hours and then fed 3 ml of 25% (v/v) ethanol per 100g body weight and subsequently sacrificed 18 hours later. The levels of triacylglycerols and total cholesterol were significantly raised in serum and liver of alcohol fed rats. However, when rats were fed on aqucous extract of onions (300 mg per 100g body weight) with 25% ethanol, no rise in serum and liver lipids was observed. Alcohol fed to the fats with or without onion extract had no effect on serum, AST, ALT and alkaline phosphatase levels. The increase in serum urea in ethanol-fed rats was not altered in rats fed a mixture of alcohol and onion extracts. Values of liver MDA was lower in rats fed ethanol with or without onion extract compared to controls. Onion extract seemed to show a hypolipidemic effect in alcohol fed rats.     

Perception of career barriers: The importance of gender and ethnic variables

Differences of gender and ethnicity were examined in terms of the perception of barriers to career development. The Perception of Career Barriers Inventory (IPBC) was administered to a sample of 457 ninth grade students in Portuguese state schools. Gender differences were found, with girls generally scoring higher and in particular on some specific scales. African ethnic participants score higher than Portuguese participants across all the IPBC scales. These findings are more obvious with African participants born in Africa than with those born in Portugal. Implications for future research and practice are discussed.     

Assessing college student perceptions of instructor customer service via the Quality of Instructor Service to Students (QISS) Questionnaire

This study presents the results of a three‐step project designed to: (1) identify what students perceive to be quality service as offered by instructors, (2) relate the dimensions identified to an appropriate survey instrument (the QISS) and pilot‐test the instrument, and (3) survey a stratified representative sample of the undergraduate population with the instrument. A stratified sample of students (N=457) were surveyed using the QISS questionnaire in the spring semester of 2004. The QISS is a modified SERVQUAL questionnaire. Results indicate that students consistently identify Reliability and Responsiveness as the most important dimensions of instructor service to students. Female students consistently report that their experiences with instructors do not meet their expectations. The same holds true for males but to a lesser degree. Information provided from this kind of assessment provides a means of identifying areas where student satisfaction is already strong and areas where it can be improved.     

EFFECTIVENESS OF THE FRIENDS FOR LIFE PROGRAM IN PORTUGUESE SCHOOLS: STUDY WITH A SAMPLE OF HIGHLY ANXIOUS CHILDREN

The FRIENDS for Life program is a cognitive–behavioral group program that targets anxiety in children. The main purpose of this study was to analyze the effectiveness of the Portuguese version of the FRIENDS for Life Program, which was implemented in schools to reduce anxiety problems in a group of highly anxious children. The study used a quasi‐experimental research design with two groups of children, an intervention (n = 17) and a wait‐list control group (n = 21), aged 8 to 12 years old. The impact of the program in reducing anxiety symptoms as assessed by children and mothers was analyzed through the Screen for Child Anxiety Related Emotional Disorders‐Revised (SCARED‐R). The results show a statistically significant post intervention effect on anxiety symptoms evaluated by the child, but not by the mother. The implications of these results for the prevention of anxiety disorders in Portuguese schools are discussed.     

UNIVERSITY LIBRARIES AND INTERDISCIPLINARY STUDY IN THE COMPUTER AGE

Through increasingly sophisticated computerization, libraries will evolve from being passive depositories of published materials to becoming dynamic information systems. Stored information will be analyzed and recoinbined in original ways which are similar to the processes occurring on the frontiers of disciplines which are giving rise to new combined disciplines: Thus the partnership of computerized information systems and interdisciplinary scientific research will vastly widen the frontiers of human discovery.     

The effects of the recession on workers' moral,ethical, and interpersonal behavior

This article presents study findings from 50 members of the Los Angeles workforce, who were also college students. The study attempted to discover the perceptions of these workforce members about the effects of the recent economic downturn on their work environment. Some interesting findings emerged from this study. Explanations are offered, and the authors encourage readers to conduct their own simple survey to discover the impact of the recession or other changes on their workplaces.     

A Fistful of Headings: Name Authority Control for Video Recordings

Lower DVD costs and increased patron demand have led to more video recordings in library catalogs. With long lists of cast and crew, these catalog records are more detailed than many books. For institutions requiring authorized name headings, both personal and corporate, heavily detailed catalog records for video recordings can be burdensome. Not all libraries that contribute original cataloging records to utilities such as OCLC are authorized to create corresponding authority records. A recent survey asked a sample of catalog librarians of video recordings in different types of libraries about their viewpoints and workflows in the context of authority control.     

Development of legal expertise

In a comprehensive empirical investigation (N = 71,405) we analyzed the development of legal expertise in a critical 1-year period of academic legal training in which advanced law students start practicing to solve complex cases. We were particularly interested in the functional form of the learning curve and inter-individual differences in learning. Performance increases monotonically with the number of practice exams following a slightly concave learning curve without any considerable kinks. Considering the performance development over time, however, the curve is not monotonic and shows intermediate drops in performance. We provide evidence which suggests that these drops are due to cyclic drops in motivation. There are about equally sized marginal effects of practicing law exams in general and practicing exams in the specific area of law. However, students with high (vs. low) initial performance profit more from practicing exams within a specific area of law whereas students with low initial performance profit more from practicing exams in general. The concave increase in performance with the number of practicing exams is mainly driven by individuals with low initial performance. Those with high initial performance mainly display a linear learning trend. We discuss the practical implications of these findings for academic legal training.
