Hospitals and consumer health information in New Zealand: the role of the library

A research project was conducted with the primary objective of finding out what New Zealand hospitals are doing about providing consumer health information to patients, and specifically, the role played by hospital libraries. A database was compiled of all New Zealand hospitals, both public and privately funded. An individual responsible for consumer health information was identified at each hospital and a questionnaire sent directly to them. A 64% response rate was achieved, representing 196 hospitals. Fifty‐four hospitals reported having an in‐house Library or Information Centre for patients, but the materials and services provided varied widely. Results from this survey show that the provision of consumer health information in the hospital sector in New Zealand is ad hoc, and libraries are not necessarily involved.     

Exploring strategies for online teaching and learning

This paper explores various strategies for creating engaging online learning environments. It describes a framework which identifies and distinguishes between the critical elements needed in the design of online learning: the content of the course, the learning activities and the learning supports. It demonstrates through practical examples how each of these elements can be manipulated in deliberate ways to influence learning processes and outcomes. The paper supports the notion that online courses are best when they arc engineered to take advantage of the learning opportunities afforded by the online technologies, rather than being used as supplements to conventional teaching programs.     

Regularized Structural Equation Modeling

A new method is proposed that extends the use of regularization in both lasso and ridge regression to structural equation models. The method is termed regularized structural equation modeling (RegSEM). RegSEM penalizes specific parameters in structural equation models, with the goal of creating easier to understand and simpler models. Although regularization has gained wide adoption in regression, very little has transferred to models with latent variables. By adding penalties to specific parameters in a structural equation model, researchers have a high level of flexibility in reducing model complexity, overcoming poor fitting models, and the creation of models that are more likely to generalize to new samples. The proposed method was evaluated through a simulation study, two illustrative examples involving a measurement model, and one empirical example involving the structural part of the model to demonstrate RegSEM’s utility.     

Teaching Statistics in US — An Alien's s-eye View

This article discusses the author's initial experience of teaching statistics in an American university, and the sort of way he thinks the subject should be taught. (Specifically, he looks at the assumption of normality, and indicates how conventional treatment in the area of hypothesis testing might be modified.) His comments primarily apply to elementary service courses, and particularly to those provided for business students.     

Three studies of factors affecting the attitudes of blacks and females toward the pursuit of science and science-related careers

This study involved the development of an instrument, the Science Career Predictor Scale (SCPS), which assesses seven factors thought to be involved with science career choices: teacher/counselor encouragement, participation in science-related hobbies and activities, academic self-image, science-related career interest, parental encouragement and support, the perceived relevance of mathematics and science, and mathematics and science ability. This instrument was administered to a sample of 522 middle and high school students, and a sample of 185 students from an historically black university, and the effects of such factors as sex, race, personal acquaintance with a scientist, and type of community (rural or urban) on the above-mentioned variables were ascertained using a multivariate analysis of covariance with age as the covariate. A separate study on a sample of 81 high school students looked at race and gender differences in critical thinking abilities as measured by the Watson-Glaser Critical Thinking appraisal, and how these abilities correlated with scores on the Science Career Predictor Scale. These studies produced several significant findings. Female subjects did produce significantly lower scores on the career interest factor. Black students actually had significantly higher science-career preference scores than their white counterparts. However, blacks scored significantly lower on the measure of critical thinking ability. Across both races and both sexes, however, the major factor affecting science-related career decisions appears to be personal contact with a scientist. The implications of these findings are discussed, along with possible strategies for increasing the participation of these groups in science.     

Safe Schools/Healthy Students initiative: Pinellas County,Florida

The Safe Schools/Healthy Students (SS/HS) Initiative in Pinellas County, FL, emerged as a part of a broader local effort to implement creative educational and mental health programs to support children and families. This initiative focused on capacity building, prevention, and intervention efforts and comprehensive evaluation to address the barriers to learning and enhance healthy development. This article describes Pinellas County's plan, and highlights the instrumental roles played by school psychologists, which included grant writing, program and resource coordination, clinical services, program evaluation, staff training, parent advocacy, and steering committee membership. Promising outcomes and generalization of these findings to other communities is also discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 489–501, 2003.     

Exploring Spanish pre-service teachers’ talk in relation to ICT: balancing different expectations between the university and practicum school

Information and communications technology (ICT) now plays a prominent role in pre-service teacher education programmes across the globe. Despite this emphasis, research indicates that pre-service teachers’ use of ICT is often less than expected, even though they express positive opinions of its benefits. This study aimed to explore pre-service teachers’ views of ICT and consider the function of their expressed opinions. This longitudinal study, using one-to-one semi-structured interviews, was conducted with pre-service teachers on entry and on completion of a one-year Masters programme in Spain. The pre-service teachers held quite traditional views of teaching and learning, presenting teaching in an either–or manner – either ICT supported or non-ICT supported. They also spoke positively about ICT while simultaneously expressing reservations about it. The article argues that these contradictory positions may be a result of the need to navigate two competing environments, the higher education institution and the practicum school, where expectations of ICT use may differ. The article explores this performative function of their talk.     

Long-term inhibition of Na+/H+ exchange attenuates cardiac remodeling after myocardial infarction in rats

Objective: In addition to pH regulation, Na⁺/H⁺ exchange (NHE) has been shown to facilitate cell growth and proliferation. However, the effects of long-term inhibition of Na⁺/H⁺ exchange on cardiac structural and functional remodeling post myocardial infarction (MI) are still controversial. The present study was therefore carried out to further investigate the effects of long-term treatment with cariporide, a specific inhibitor of NHE-1, on cardiac remodeling after MI in rats; Methods: Male Wistar rats that underwent coronary ligation were randomly selected for cariporide treatment starting 6 h after induction of MI or no treatment. Treatment was continued up to 6 weeks post MI, after which, the arterial, venous and left ventricular catheters were chronically implanted. Twenty-four h later, after hemodynamic signals were recorded in conscious rats, they were sacrificed and hearts were taken out for morphological examinations; Results: Cariporide treatment decreased the heart weight and heart weight to body weight ratio (bothP<0.05), decreased left ventricular end-diastolic pressure (P<0.001), improved myocardial contractility (dP/dt _max) (P<0.05) and tended to increase the survival of treated rats compared to that of untreated infarct rats; Conclusion: The results of the present study indicate that the long-term inhibition of NHE with cariporide can attenuate cardiac structural remodeling and improve left ventricular dysfunction in infarcted rats, and suggest that Na⁺/H⁺ exchange inhibition could be an effective therapeutic strategy for myocardial infarction-induced heart failure.     

Schulformen als differenzielle Lernmilieus Institutionelle und kompositionelle Effekte auf die Leistungsentwicklung im Fach Franz?sisch

Auf der Basis von zwei repr?sentativen Schülerstichproben der Schweizer Kantone Wallis (N = 926) und Fribourg (N = 778), die w?hrend der 8. Jahrgangsstufe im Fach Franz?sisch als Fremdsprache unterrichtet wurden, geht der vorliegende Beitrag der Frage nach, ob Schülerinnen und Schüler je nach besuchtem Bildungsgang unterschiedliche Fortschritte in der Entwicklung ihrer Fachleistungen machen. Von besonderem Interesse ist dabei, ob und in welchem Ausma? die Zusammensetzung der Schülerschaft (Kompositions-effekte) und m?glicherweise auch institutionell differierende didaktische und curriculare Angebote zwischen den Bildungsg?ngen (Institutionseffekte) als lernmilieupr?gende Faktoren von Bedeutung für die Entwicklung der Fachleistungen sind. In Mehrebenenanalysen zeigten sich auch nach Kontrolle der individuellen Eingangsvoraussetzungen (einschlie?lich des Vorwissens) bedeutsame Unterschiede in den Lernzuw?chsen an den verschiedenen Bildungsg?ngen. Die weiteren Analysen lassen darauf schlie?en, dass sowohl von kompositionellen als auch institutionellen Effekten auf die Leistungsentwicklung auszugehen ist.
