Attention‐Deficit/Hyperactivity Disorder (ADHD): A national survey of training and current assessment practices in the schools

The primary purpose of this research was to survey school psychologists to investigate their training and current assessment practices for attention‐deficit/hyperactivity disorder (ADHD) in the schools. The survey consisted of 38 questions regarding participant characteristics and three main areas relevant to ADHD: (a) training, (b) caseloads/referral patterns, and (c) assessment. The respondents reported receiving adequate training in the assessment of ADHD, with doctorate‐level psychologists self‐reporting being better trained than nondoctorate psychologists. Results confirmed a substantial caseload of ADHD referrals. In the assessment of ADHD, the results indicated school psychologists are using multiple informants, methods, and settings for the assessment of ADHD with rating scales, observations, and interviews the most common methods identified. Limitations of current practices will be discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 583–597, 2003.     

Scholarly Productivity Redefined in Counselor Education

In this study, counselor educators responded to a survey about their scholarly productivity over a 3‐year period. Their involvement in 7 scholarly activities is reported by category and by type of institution, tenure status, academic rank, and gender. Using a more comprehensive definition of scholarly productivity, this study documents that counselor educators are involved in a much broader, more diversified spectrum of scholarly activities than prior studies of scholarly productivity have indicated. Implications for tenure and promotion decisions, along with recommendations for training and mentoring of future counselor educators as well as future directions for research, are discussed.     

College tuition costs and early career socioeconomic achievement: do you get what you pay for?

The effects of college tuition costs on early career educational, occupational and economic achievements were estimated for a national sample of black and white college students. The findings suggest that attending a relatively high tuition college has a net positive influence on such outcomes as educational attainment, occupational status, income and women's entry into sex-atypical careers. These effects remained significant even when controls were made for student background characteristics (e.g., socioeconomic origins, secondary school achievement, educational and occupational aspirations); the academic selectivity, private/public control, size and graduate orientation of the college attended; and one's specific college experiences (e.g., academic major, academic achievement and social involvement). The findings are discussed in terms of several plausible causal mechanisms.

What do individuals in different science groups within a life sciences organization think about genetic modification?

An assessment was undertaken of the attitudes of individuals within the science community towards a program to produce genetically modified cattle for altered milk composition, expectantly allowing for research into the treatment of multiple sclerosis in humans. The majority of respondents to an electronic survey expressed favorable attitudes to the program, thought it beneficial, respected individual freedom and was fair and just and disagreed that it was harmful. A passion for science and having a suitable lifestyle were the most important motivating factors for individuals. Finally, there were a wide range of responses to a number of cultural beliefs or myths. Science grouping significantly affected the responses. Compared with Systems and Land groups, Plant and Reproduction groups more strongly agreed with the project, thought it less harmful to interest groups, felt that genetic modification of animals was more morally acceptable, and more strongly agreed with the myth statements. These results indicate a diversity of beliefs and attitudes towards genetic modification amongst those within the science community, and highlight the importance of understanding ethics and myths in dealing with them. It is suggested that the diversity of beliefs could be better used to help shape public policy and understanding of biotechnology.     

Knowledge management research & practice: visions and directions

College quality and early adult outcomes

This paper estimates the effects of various college qualities on several early adult outcomes, using panel data from the National Education Longitudinal Study. I compare the results using ordinary least squares with three alternative methods of estimation, including instrumental variables, and the methods used by Dale and Krueger [(2002). Estimating the payoff to attending a more selective college: An application of selection on observables and unobservables. Quarterly Journal of Economics, 117(4), 1491–1528.] and Black and Smith [(2004). How robust is the evidence on the effects of college quality? Evidence from matching. Journal of Econometrics, 121, 99–124.]. I find that college quality does have positive significant effects on most outcomes studied using OLS. While there is some evidence of positive selection bias in the OLS results, the alternative methods rarely produce findings that are significantly different from the OLS estimates. Furthermore, alternative methods have their own limitations, which are discussed. Across methods of estimation, there is solid evidence of positive effects of college quality on college graduation and household income, and weaker evidence of effects on hourly wages.
