Beautiful colored interference rings can be produced by using transparent plates such as window glass. A simple model explains this effect, which was described by Newton but has almost been forgotten. (Contains 11 figures.)

Health and social care researchers, in their haste to "belong" to academia, have adopted the system of mixed methodology research, overestimating its ability to reveal the truth and occasionally imprisoning their thought in one system. In this article, some of the assumptions underpinning mixed methodology research and its discourse are subjected…

The paper examines the extent to which diversity in the backgrounds of students and diversity in the forms and characteristics of universities combine to produce diversities in learning experiences and outcomes. It draws on a recent major national study in the UK which has been investigating how student learning is mediated by a series of social…

Although genetic influences on individual differences in activity level (AL) are well documented, few studies have considered the etiology of AL from a contextual perspective. In the present study, cross-situational and context-specific genetic effects on individual differences in AL at age 2 were examined. The AL of 312 twin pairs (144…

Little is known about the impact of the relational context of adolescent sexual activity on depressive symptoms. The present study examined trajectories of depressive symptoms among 6,602 adolescents (44% male, 60% White) taken from a nationally representative study (Add Health). Sexually active youth in romantic and casual relationships were…

Why do inventors and top scientists from leading universities exploit their research results differently from others? Why do apparently similar laboratory experiences make "academic entrepreneurs" achieve different entrepreneurial goals? Does the academic experience have an influence on the willingness to spin off? Or is that willingness simply…

Background: Alternative certification plays a central role in the production of new teachers in many states, yet little is known about the characteristics of an effective program. Given that the variation within programs is as great as the variation between programs, the common methodology of comparing programs is unable to discern the qualities…

Dreaming is an integral part of human life. Whilst psychology has generated extensive knowledge and understanding about dreams, it was in religious contexts that they were originally understood. This relationship between dreams and religion is still evident in contemporary society in the scriptures of the Abrahamic faiths, which narrate dreams…

In this study, we measure the impact of the services of a large Southern state's literacy resource center on the state's adult literacy programs. Too often, literacy resource centers are the "forgotten player" in the field of adult literacy, being omitted from policy discussions. The findings from this study indicate that the services of…

Readers typically experience processing difficulty when they encounter a word that is anomalous within the local context, such as "The mouse picked up the "dynamite...". The research reported here demonstrates that by placing a sentence in a fictional scenario that is already well known to the reader (e.g., a "Tom and Jerry" cartoon, as a context…

Research on professional development (PD) typically focuses on what teachers learn as a result of their participation in PD. Questions are framed unidirectionally: To what extent does participation in PD affect teachers' classroom practice? The authors challenge this unidirectional conceptualization of teacher learning and instead argue for…

Assessment has become an important topic of debate and even reform in many Western countries. It is equally important in other regions of the world, although less subject to reform. Yet discussions of assessment across cultural boundaries are not frequent and in a globalizing world this can be problematic. The purposes of this article, therefore,…

Forget the pills, hypnosis, and meditation. Losing weight or boosting self-confidence can be achieved by adopting an avatar and living in virtual reality, says Jeremy N. Bailenson, an assistant professor of communications at Stanford University. As the director of Stanford's Virtual Human Interaction Lab, Mr. Bailenson has explored ways that…

The purpose of this article is to explore the meanings and implications of dangerous memories in two different sites of past traumatic memories: one in Israel and the other in Cyprus. Dangerous memories are defined as those memories that are disruptive to the status quo, that is, the hegemonic culture of strengthening and perpetuating existing…

Background/Context: Educational policy makers have begun to recognize the challenges posed by teacher turnover. Schools and students pay a price when new teachers leave the profession after only 2 or 3 years, just when they have acquired valuable teaching experience. Persistent turnover also disrupts efforts to build a strong organizational…
