High-risk sexual behavior and knowledge of HIV antibody status in the San Francisco City Clinic Cohort.

Evaluated the effectiveness of human immunodeficiency virus (HIV) testing and counseling among homosexual and bisexual men participating in the San Francisco City Clinic Cohort (Centers for Disease Control, 1987). Behavioral data from 181 men who learned their HIV antibody status between 1985 and 1987 were compared with data from 128 men who were tested but declined to receive their results. Significant declines in risk indices for unprotected receptive and insertive anal intercourse occurred between 1983–1984 and 1986–1987, but these declines were independent of both knowledge of HIV status and actual serostatus. Ss who chose to learn their HIV status were no more likely to report depression or anxiety subsequent to testing. Frequent access to and discussion of risk-reduction information may be important motivators of behavioral change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

First documentation of spawning and nest guarding in the laboratory by the invasive fish,the round goby (Neogobius melanostomus)

Although the round goby, Neogobius melanostomus, is widespread in the Great Lakes and has an extended breeding season with a high reproductive rate; its spawning behaviour remains elusive. We present the first reported accounts of spawning by the round goby in the laboratory. By simulating winter conditions and restoring spring conditions, we induced round gobies to spawn in October 2007, March 2008, May 2008, and January 2009. In one case, fanning by the nest-holding male began 10 days before egg deposition and, during this period, the male rubbed secretions along the ceiling of the nest. Males were choosy about which gravid females entered the nest and prevented entry by some females. Spawning involved repeated inversions by females and males releasing gametes on the ceiling of the nest. Males guarded the nest by blocking the entrance, producing agonistic vocalizations and chasing intruders. Inside the nest, eggs were regularly inspected by the males and constantly ventilated using pectoral and caudal fins. Up to three gravid females spawned sequentially in a nest. Peak ventilation occurred after egg deposition and declined with time until the parental male ate the eggs. The decline of parental care and egg cannibalism was likely an artifact of laboratory conditions and small brood size. Our findings offer new information on the reproductive habits of the invasive round goby. Because the reproductive sequence in the laboratory seems easy to disrupt, the procedures may lead to a management tool to control the spread of the species into new areas.     

The emerging professional adhocracy: A general framework of responsive organizing (a republication).

This reprinted article originally appeared in Consulting Psychology Journal: Practice and Research, 1997, Vol 49(1), 25-34. (The following abstract of the original article appeared in record 1997-30041-003.) Offers a framework of the characteristics of the responsive organization. A responsive organization is one in which structures and procedures enhance the organization's ability to take advantage of the changes in the environment. Responsiveness, in this case, is more than just being reactive; it means that an organization is able to anticipate change and maintain a proactive orientation to the external environment. Within the framework discussed, the authors also include some of the problems that might be expected in this new organizational form. It is suggested that these tools will allow for the systematic examination of organizational performance and assist change agents in facilitating efforts intended to result in more responsive organizing.

Self-regulation of motor vehicle advertising: is it working in Australia?

There is growing concern that certain content within motor vehicle advertising may have a negative influence on driving attitudes and behaviours of viewers, particularly young people, and hence a negative impact on road safety. In response, many developed countries have adopted a self-regulatory approach to motor vehicle advertising. However, it appears that many motor vehicle advertisements in Australia and elsewhere are not compliant with self-regulatory codes. Using standard commercial advertising methods, we exposed three motor vehicle ads that had been the subject of complaints to the Australian Advertising Standards Board (ASB) to, N = 463, 14–55 year olds to assess the extent to which their perceptions of the content of the ads communicated themes that were contrary to the Australian self-regulatory code. All three ads were found to communicate messages contrary to the code (such as the vehicle's speed and acceleration capabilities). However, the ASB had upheld complaints about only one of the ads. Where motor vehicle advertising regulatory frameworks exist to guide motor vehicle advertisers as to what is and what is not acceptable in their advertising, greater efforts are needed to ensure compliance with these codes. One way may be to make it mandatory for advertisers to report consumer pre-testing of their advertising to ensure that undesirable messages are not being communicated to viewers.     

Quantifying Precision and Availability of Location Memory in Everyday Pictures and Some Implications for Picture Database Design.

The authors investigated whether memory for object locations in pictures could be exploited to address known difficulties of designing query languages for picture databases. M. W. Lansdale's (1998) model of location memory was adapted to 4 experiments observing memory for everyday pictures. These experiments showed that location memory is quantified by 2 parameters: a probability that memory is available and a measure of its precision. Availability is determined by controlled attentional processes, whereas precision is mostly governed by picture composition beyond the viewer's control. Additionally, participants' confidence judgments were good predictors of availability but were insensitive to precision. This research suggests that databases using location memory are feasible. The implications of these findings for database design and for further research and development are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Focus Groups in Psychological Assessment: Enhancing Content Validity by Consulting Members of the Target Population.

A review of articles in Psychological Assessment reveals that many researchers develop instruments without the benefit of consultation with members of the target population. To the extent that researchers do consult the target population, most fail to bring consultation in early enough to inform the identification and specification of key constructs. Moreover, this consultation typically takes the form of one-to-one interviews. The authors' goal in this article was to elaborate on the importance of population consultation as part of content validation and to critically evaluate the potential of one method of consultation, focus groups, to inform multiple stages of instrument development. The authors suggest that this method holds promise for enhancing the content validity of instruments and, ultimately, the validity of research findings.

A novel paradigm to investigate regulation of drug intake in rats self-administering cocaine or heroin intravenously.

The purpose of this experiment was to investigate the regulation of drug intake in rats (n?=?20) self-administering heroin or cocaine during daily 5-hr sessions. Operant chambers were equipped with 2 levers and associated stimulus lights. A response on the lever with stimuli signaling an increase in dose size increased the infusion duration by 3 s, and a response on the lever with stimuli signaling a decrease in dose size decreased the infusion duration by 3 s. Results showed that daily and hourly drug intake for cocaine and heroin groups were relatively constant. Significant correlation coefficients were obtained for heroin and cocaine groups for the relationship between interdose interval (IDI) and infusion duration (dose size). These findings indicate that subjects regulated their drug intake by adjusting IDI throughout drug self-administration sessions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
