EVALUATING STATE STUDENT GRANT PROGRAMS: A Case Study of Washington's Grant Program

The lack of workable approaches for evaluatingthe effects of state student grant programs may havecontributed to the problems that advocates for theseprograms have had in securing funding in the past decade. This study pilot tests a new, moreworkable approach to assessing the effects of changes infunding for state grant programs on college persistence.This case study of the State of Washington's grant program indicates that an increase instate funds for need-based grants in 1993-94 resulted inimproved within-year persistence in public four-yearuniversities. The study illustrates that it is possible for states to undertake systematic evaluationsof their grant programs.     

Perceived Norms and Marijuana Use at Historically Black Colleges and Universities

Relatively little is known about the extent of marijuana use and related risk‐taking behavior by college students on historically Black colleges and universities (HBCUs). Undergraduate students (N = 212) from an HBCU in the southern region of the United States completed anonymous questionnaires that assessed their marijuana‐related behaviors and perceptions. Logistic regression analysis revealed risk factor profiles that provide college counselors with greater insight into prevention and treatment on HBCU campuses.     

The timing of middle-childhood peer rejection and friendship: linking early behavior to early-adolescent adjustment

This study used a sample of 551 children surveyed yearly from ages 6 to 13 to examine the longitudinal associations among early behavior, middle-childhood peer rejection and friendedness, and early-adolescent depressive symptoms, loneliness, and delinquency. The study tested a sequential mediation hypothesis in which (a) behavior problems in the early school years are associated with middle-childhood peer rejection and (b) rejection, in turn, leads to lower friendedness and subsequently higher adolescent internalizing--but not externalizing--problems. Results supported this sequential mediation model for internalizing outcomes and revealed an additional path from early disruptiveness to loneliness via peer rejection alone. No evidence of sequential mediation was observed for delinquency.     

Variations in methods of calculating reliability of duration data

The traditional percentage and correlational methods of estimating reliability of duration recording were compared to the reliability obtained with an event-by-event examination of observers' records in which the actual percentage of time that the observers were in agreement was calculated. While observing standardized videotapes, eight volunteer undergraduate students recorded “studying” using a specific definition and “not eating” using a nonspecific definition. The order of persentation and level of definition specificity were reversed for eight additional volunteer observers. Recordings were done on an event recorder. It was found that the traditional percentage reliability scores were significantly higher than actual (event-by-event) observer agreement for both behaviors, at both levels of definition specificity. Correlational reliability coefficients were significantly greater than event-by-event scores for specific definitions only. Implications of the findings include the possibility that duration recording, which does not involve a permanent product (e.g., when using a stopwatch), may be periodically checked for reliability with an event recorder, or that interval recording may be used.

Efficient capture of circulating tumor cells with a novel immunocytochemical microfluidic device

Ability to perform cytogenetic interrogations on circulating tumor cells (CTCs) from the blood of cancer patients is vital for progressing toward targeted, individualized treatments. CTCs are rare compared to normal (bystander) blood cells, found in ratios as low as 1:10⁹. The most successful isolation techniques have been immunocytochemical technologies that label CTCs for separation based on unique surface antigens that distinguish them from normal bystander cells. The method discussed here utilizes biotin-tagged antibodies that bind selectively to CTCs. The antibodies are introduced into a suspension of blood cells intending that only CTCs will display surface biotin molecules. Next, the cell suspension is passed through a microfluidic channel that contains about 9000 transverse, streptavidin coated posts. A CTC making contact with a post has the opportunity to engage in a biotin-streptavidin reaction that immobilizes the cell. Bystander blood cells remain in suspension and pass through the channel. The goal of the present study is to establish the technical performance of these channels as a function of antigen density and operating conditions, especially flow rate. At 18 μL/min, over 70% of cells are captured at antigen densities greater than 30 000 sites/cell while 50% of cells are captured at antigen densities greater than 10 000. It is found that lower flow rates lead to decreasing cell capture probabilities, indicating that some streamlines develop which are never close enough to a post to allow cell-post contact. Future modeling and streamline studies using computational fluid dynamics software could aid in optimization of channel performance for capture of rare cells.     

Information,knowledge and wisdom: groundwork for the normative evaluation of digital information and its relation to the good life

This paper provides a general philosophical groundwork for the theoretical and applied normative evaluation of information generally and digital information specifically in relation to the good life. The overall aim of the paper is to address the question of how Information Ethics and computer ethics more generally can be expanded to include more centrally the issue of how and to what extent information relates and contributes to the quality of life or the good life, for individuals and for society. To answer that question, the paper explores and provides by way of a theoretical groundwork for further research, the concept of wisdom understood as a type of meta-knowledge as well as a type of meta-virtue, which can enable one to both know in principle what a good life is and how to successfully apply that knowledge in living such a life in practice. This answer will be based on the main argument presented in this paper that the notion of wisdom understood as being at once a meta-epistemological, meta-axiological and meta-eudemonic concept, provides the essential conceptual link between information on the one hand and the good life on the other. If, as we are told, this is the Age of Information, both the theoretical examination and analysis of the question of how information relates to the good life and the provision of an adequate answer to that question are essential for developing a deeper understanding of how to evaluate the theoretical and practical implications and ramifications of information for the good life, for individuals and societies generally.     

Towards a methodology to determine standard time allocations for academic work

An online survey of workload activities was circulated to academics across Australia seeking estimates for the time to undertake a range of academic-related tasks associated with teaching, research and service. This article summarises the most important findings from the teaching data of the 2059 respondents. This detail of workload data has not been reported before across the Australian university sector. The findings showing that most academics work more than 50 h per week are consistent with previous studies. Although the estimates of the individuals varied greatly, statistical inquiry indicated the median time required does not vary by experience and online teaching generally requires more preparation time than on-campus teaching. The paper proposes this methodology as a credible means to derive realistic time-based standards for other aspects of academic work and will assist university managers by providing an external benchmark upon which to develop local academic workload models.
