Determinants of foster care placement for the maltreated child

This study examined the records of the North Carolina Central Registry of Child Abuse and Neglect to determine which social, family, and child characteristics were most influential in the decision to place a child in foster care. These records contained all theoretically relevant factors as well as demographic data. Analysis included the computation of odds ratios for foster care for each of 250 variables. A maximum likelihood logistic regression model was constructed to obtain the independent and cumulative contribution of each factor. Some expected variables such as parental stress factors (substance abuse) and types of abuse (burns and scalds) placed a child at a significant risk for placement in foster care (p < 0.01). However, less obvious factors such as referral source (law enforcement agencies) or geographic area also placed children at risk. Overall, the model explained little of the variance of these decisions (R² = 0.168) and poorly predicted placement (sensitivity 66.3 per cent, specificity 74.6 per cent). Using existing data. we were unable to adequately describe the decision process in selecting foster care.     

Brokers on the boundary: Academy-industry liaison in Canadian universities

As scientific research has taken on increasingeconomic significance so research managementhas become a priority for universities and theState. Over the last two decades,Industry-Liaison Offices have become anestablished part of the infrastructure ofCanadian universities. The managers of theseoffices are the quintessential boundary workerswho are charged with translating academicscience into intellectual property. Someuniversities operate with an `internal' modelwhere the office is fully integrated into theuniversity's structure. Other universitiesoperate with an `external' model where theoffice operates outside the university eitheras a non-profit or a for-profit corporation.This article traces the institutionalization ofthese offices and commercialization in Canadianuniversities. Using documentary analysis andinterviews we document the key issues for thesemanagers in four `case' study universities, asthey attempt to commercialize universityresearch. We describe how these managers`capture the benefits' of discoveries generatedby researchers – the process of identifying,protecting, and exploiting intellectualproperty. Finally, we identify four majorthemes: intellectual property policy; cultureconflict; boundary work; and the public good. We end by raising the question about what islost when `capital' is allowed to enteruniversity culture in such a direct manner.     

Analyzing Medical Students' Definitions of Sex

An inaccurate definition of what constitutes sex can negatively impact the sexual health and wellbeing of patients. This study aimed to determine which behaviors medical students consider to be sex. Survey questions about various sexual behaviors were administered to medical students. All participants agreed that penile-vaginal penetration is sex. More than 25% of participants did not consider genital-genital contact without penetration, oral-genital contact, foreign object in rectum, and forced vaginal/rectal penetration as sex. Nonheterosexuals were more likely to consider genital-genital contact without penetration sex. We determined there was less than complete consensus among future physicians on what activities are considered sex.     

Behavioral and pharmacological influences on phencyclidine discrimination in the pigeon

Discriminative stimuli produced by drugs control behavior in the same way as exteroceptive discriminative stimuli control behavior, despite the difficulty in controlling the intensity of the discriminative stimulus properties of drugs throughout test sessions. In recent years, many investigators have correlated the potency of drugs as discriminative stimuli, with their affinity for specific pharmacological receptors. High correlations have been interpreted as evidence that the discriminative stimulus properties of drugs are mediated by these specific pharmacological receptors. However, the relationship between discriminative stimulus potency and receptor affinity can be confounded by other pharmacological effects of drugs, such as their ability to produce position responding, and by behavioral variables, such as the schedule of reinforcement under which the drug discrimination is established and measured.     

Rate of a maintained operant as a function of temporal position within a session

McSweeney and her colleagues (e.g., McSweeney, Hatfield, & Allen, 1990) have demonstrated reliable, large magnitude rate changes in maintained operants within daily sessions under a wide variety of reinforcement schedules. The present paper examined the role of schedule of reinforcement, reinforcement rate, and total amount of food access in determining those within-session rate changes. When median rates across birds were considered, all procedures resulted in a brief period of an increasing rate, followed by a modest rate loss across the major portion of the session. However, not all individuals exhibited that pattern. When the amount of food access per session was limited by lower reinforcement rates, shorter sessions, or shorter reinforcement durations, the magnitude of the withinsession rate change was reduced from that occurring without those constraints. Additionally, under the conditions that produced strong within-session rate changes, the magnitude of the within-session rate loss was correlated with the bird’s body weight. These effects are consistent with what is typically labeledsatiation.     

Australian and South Pacific External Studies Association: ODLAA’s regional predecessor

The Australian and South Pacific External Studies Association (ASPESA) – the predecessor of the Open and Distance Learning Association of Australia, Inc. (ODLAA) – was founded in 1973. From the outset, ASPESA adopted a broader‐than‐Australia focus for open and distance learning that included New Zealand, Papua New Guinea, and the member countries of the University of the South Pacific. Its interest was firstly on ‘professional’ matters (i.e., an identity for distance education, distance educators, and their professional development). ASPESA forums and workshops spread through various Australian ‘external studies’ institutes and developed the practical and intellectual infrastructure for ASPESA’s aims and objectives.

ASPESA acknowledged its regional and international focus in various ways. The 1981 ASPESA forum was organised jointly by the University of the South Pacific and Massey University, New Zealand, and held in Fiji. Thereafter its regional members played a larger role in ASPESA activities and regional issues appeared on forum agenda. ODLAA and its companion associations around the South Pacific received from their predecessor, ASPESA, a heritage of professionalism and participation in regional and international open and distance learning. In due course, however, differences in distance education environments led New Zealand, Papua New Guinea, and then the Pacific island countries to form separate distance education associations, while maintaining links with ASPESA.
