The State of Sleep Among College Students at a Large Public University

Abstract

Objective: Data about college student sleep were collected and used to develop an education campaign to improve sleep. Participants: On-campus residents at a large state university were surveyed on 4 occasions, October 2005 to April 2007. Sample size was 675 to 1,823 students. Fall 2005 mean age = 18.5 years, SD = 1.03 (range 18–30) years. Initial survey included 935 males and 1,859 females (2005–2006). Matched pairs data (2006–2007) included 91 males and 107 females. Twenty-six males and 22 females participated in interviews. Methods: A survey administered online included the Pittsburgh Sleep Quality Index, along with an 8-question in-person interview. Results: Poor sleep interacted with academics and mental health, and an education campaign positively affected student sleep. Conclusions: Teaching students how to effectively manage sleep can improve their well-being. Sleep may also be a gateway topic for health care professionals to address sensitive health issues such as depression.     

South Korean College Students' Holland Types and Career Compromise Processes

This study explored South Korean college students' career compromise processes and examined whether preferences for sex type, prestige, or interests would be differentiated by Holland theme interest types, gender, or college major. Participants were South Korean undergraduate students from 2 universities in Seoul, South Korea. They were asked to choose 1 occupation from each of 168 pairs of occupations using a forced‐choice format. A total of 376 surveys were analyzed. There were significant main effects for Holland interest types and for gender but not for college major on their career compromise processes. Implications for career counselors and researchers are discussed.     

Large Differences between Partial Correlation Coefficients

A plot of each ranking of N objects in N-dimensional space is shown to provide geometric interpretations of Kendall's tau and Spearman's rho and also of the relationship of rho to a sum of inversion weights. The computation of rho from a sum of inversion weights is shown to allow sequential calculation of rho.     

Correlation Coefficient Revisited

Elementary approaches to prove basic properties of the correlation coefficient are of pedagogical interest. Besides posing another proof, this article gives variations of the proofs already existing in the statistical literature     

THE ARCHIVE STATE AND THE FEAR OF POLLUTION: FROM THE OPIUM WARS TO FU-MANCHU

This article considers the relationship between the production of a British imperial archive on China and the global politics of empire over the last century and a half. Drawing upon the theoretical work of Bruno Latour, Gayatri Spivak and Thomas Richards,the archive is explored as a coherent set of material practices designed to decode and recode China and other colonized territories. Imagined as an interface between knowledge and the state, the British archive required the establishment of an epistemological network designed to generate knowledge on China. The knowledge so produced was then used to manipulate local scenes and to provide intelligence in ‘the Great Game’, the continuing contest with Russia over domination in Central Asia. Because of its desire for comprehensive knowledge of other peoples and places, the archive also generated its own phantasms, ones which threatened to undermine and destroy empire. This process of self-haunting is explored through the figure of Fu-Manchu, a discernible mutation of epistemological empire, and linked to the cold war which emerged on the Eurasian landmass after 1945.
