The educational literature, the popular press, and educated laypeople have all echoed a conclusion from the book Academically Adrift by Richard Arum and Josipa Roksa (which has now become received wisdom), namely, that 45% of college students showed no significant gains in critical thinking skills. Similar results were reported by Pascarella, Blaich, Martin, and Hanson after the publication of Arum and Roksa's book in 2011. However, these authors' statistical tests were conducted incorrectly, and therefore this 45% finding is fundamentally untrue. We demonstrate that a correct statistical analysis would have found that far fewer students show significant gains in critical thinking. However, this does not reflect on student learning; instead, it reflects on how hard it is to find a statistically significant result when assessing student change on a student‐by‐student basis. This article discusses valid methods for testing the significance of gain scores of individual students. 相似文献

As a result of a relative lack of cross-cultural validity in most current (Western) psychological models, indigenous models
of psychology have recently become a popular approach for understanding behaviour in specific cultures. Such models would
be valuable to vocational psychology research with culturally diverse populations. Problems facing current psychological models
and methods of improving cultural validity are discussed. An integrative model of cross-cultural psychology is reviewed and
the relevance of indigenous psychological methods to the advancement of vocational psychology is explained. 相似文献

This study examined the contributions of gender, adult romantic attachment orientations (i.e., avoidance, anxiety), defense mechanisms (i.e., narcissism, other‐splitting), and stressors to college student psychological abuse perpetration (dominance). Men with higher levels of attachment avoidance, narcissistic entitlement, and stressful problems reported more dominance of female partners. Women with higher levels of other‐splitting reported more dominance of male partners. Attachment avoidance contributed to women's dominance of male partners only in the context of elevated narcissistic entitlement or few stressors. 相似文献

In this paper, we present a microfluidic chip that is capable of measuring electrical conductance through gap junction channels in a 2-dimensional cell sheet. The chip utilizes a tri-stream laminar flow to create a non-conductive sucrose gap between the two conducting solutions so that electrical current can pass across the sucrose gap only through the cells. Using the chip, we tested the effect of a gap junction inhibitor, 2-APB, on the electrical coupling of connexin 43 (Cx43) gap junction channels in NRK-49F cells. We found that 2-APB reversibly blocks the conductivity in a dose-dependent manner. The tri-stream chip further allows us to simultaneously follow the conductance changes and dye diffusion in real time. We show that 2-APB affects both conductance and diffusion, supporting the interpretation that both sets of data reflect the same gap junction activity. The chip provides a generic platform to investigate gap junction properties and to screen drugs that may inhibit or potentiate gap junction transmission. 相似文献

How are secondary accounts of "bad" scientific practice constructed? How do they engage with the primary data produced by "bad" scientists? And what happens to those primary data as generations of secondary accounts purporting to describe them accumulate? This paper addresses such questions via a case study of Dr. Hong, a microbiologist accused of "bad" scientific practice by numerous secondary accounts of the 2003 SARS outbreak. Bringing Hong's own account of his own actions into dialogue with one of the most influential secondary accounts of his actions, the paper highlights the gross disparity between the two. Having argued that the rhetorical structuring of the secondary account is, ultimately, responsible for Hong's characterisation as a "bad" scientist, it then moves to explore how subsequent accounts developed their own characterisations. What becomes clear is that as secondary accounts began feeding off one another, references to Hong's account disappeared. Aided by the concepts of the "vanishing" and the "phantasm", the paper concludes with a consideration of how this process left Hong's work with a very peculiar form of existence. 相似文献
