It is shown that the well-known linear variation of p-n diode terminal voltage with temperature at different fixed forward currents allows easy and accurate determination of the semiconductor ideality factor and bandgap from only two data points. This is possible if the temperature difference required to maintain the same diode voltage drop can be…

It is easier than ever to survey stakeholders about issues that confront one's district. A survey offers a way to collect information from many people in a short time at a reasonable cost. The information one collects can be descriptive, such as information solicited from those who voted on the district's budget, including age, income, or whether…

This article considers the rationale for embedding research and enquiry skills early in the undergraduate geography curriculum and for making these skills explicit to students. A survey of 52 international geography faculty identified critical thinking, framing research questions, reflectivity and creativity as the most challenging research skills…

In their comment, M. L. Rohling et al. (2011) accused us of offering a "misleading" review of response bias. In fact, the additional findings they provided on this topic are relevant only to bias assessment in 1 of the domains we discussed, neuropsychological assessment. Furthermore, we contend that, even in that 1 domain, the additional findings…

Research methods modules have become a core component of a range of nursing and allied health professional educational programmes both at pre-qualifying, undergraduate level and at post-qualifying and Masters' level, in keeping with requirements of professional bodies. These courses are offered both on a full time basis and part time for qualified…

Emphasis on neuropsychiatric frameworks of conceptualizing troubled youth is increasing. This focus leads to more biologically-based interventions. As such, the use of psychotropic medications is skyrocketing, while the utilization of psychosocial strategies is diminishing. Yet overall outcomes seem to be faltering. Admissions to outpatient,…

This article outlines a set of methodological, theoretical, and other issues relating to the conduct of good outcome studies. The article begins by considering the contribution of evidence-based medicine to the methodology of outcome research. The lessons which can be applied in outcome studies in nonmedical settings are described. The article…

Although several methods have been developed to allow for the analysis of data in the presence of missing values, no clear guide exists to help family researchers in choosing among the many options and procedures available. We delineate these options and examine the sensitivity of the findings in a regression model estimated in three random…

This article presents the results of a comparison of didactics textbooks in two countries: on the one hand it examines a textbook in the tradition of German Didaktik, and, on the other hand, a textbook in the tradition of "Instructional Design" from the USA. The main research question is: How do authors write didactics textbooks? Is it…

The phenomenon of bullying has received a great deal of international attention in the last few decades. In this article, we provide a critical review of some of the major contributions from the field of educational research. We first provide an overall description of the classic concept of bullying, including certain characteristics of bullies…

Although every research method has its challenges, there are some specific challenges to the reporting and publishing of narrative inquiry that seem to differ from those encountered in other methods. Some of these arise out of the epistemology of narrative, with its focus on individual experience and interpretive storying, and some arise from the…

This paper addresses the influence of CHC on how the insider/outsider distinction is drawn and what consequences follow for the conduct of research. The paper outlines the methodological complexities faced by us whilst conducting our respective research projects in Hong Kong. In the studies reported in this paper we, the researchers, were insiders…

This article is concerned with how to analyse photographs produced during research on sexualities and schooling. Photo-diaries and photo-elicitation were employed in an examination of the sexual cultures of two New Zealand secondary schools. This visual methodology sought to disclose spatial and embodied dimensions of sexualities at school while…

This study examined how much improvement was attainable with respect to accuracy of differential item functioning (DIF) measures and DIF detection rates in the Mantel-Haenszel procedure when employing focal and reference groups with notably unbalanced sample sizes where the focal group has a fixed small sample which does not satisfy the minimum…

Three experiments with rat subjects examined resurgence of an extinguished instrumental response using the procedure introduced by Epstein (1983) with pigeons. There were three phases: (1) initial acquisition of pressing on a lever (L1) for pellet reward, (2) extinction of L1, and (3) a test session in which a second lever (L2) was inserted,…
