High school student employment in social context: adolescents' perceptions of the role of part-time work

The majority of middle-class high school students now work at part-time jobs during the academic year. During in-depth interviews, 35 seniors at a predominantly middle-class high school were asked to relate their jobs, or their decisions not to work, to the social contexts of employment. Attitudes toward the workplace and interpretations of the work ethic were analyzed within these contexts in order to examine the role of part-time employment in their lives. The findings of this study suggest that a negative stereotype of the high school student-worker is not justified. Instead, part-time work upholds a variety of interpretations of the work ethic within the framework of normative middle-class values. Future studies are needed to relate part-time work among adolescents to social and economic as well as developmental perspectives.     

Buffalo Creek Survivors in the Second Decade: Comparison with Unexposed and Nonlitigant Groups1

This study investigated the second-decade effects of the Buffalo Creek dam collapse and flood that occurred in West Virginia in 1972. One hundred twenty-one survivors who had participated in an earlier lawsuit against the coal company that built the collapsed dam were compared to 78 nonlitigant survivors on self-reported symptoms, clinical ratings, and diagnoses. A nonexposed sample from a geographically and culturally similar neighborhood was investigated as well. Findings showed no differences between the litigant and nonlitigant survivor groups. The survivor groups together showed higher rates of anxiety, depression, and hostility symptoms and diagnoses than the nonexposed sample. The findings were discussed in the context of the nature of the traumatic event, social and cultural influences on recovery, and the constellation of symptoms which differentiated the groups.     

Spatial summation of chemical irritation and itch produced by topical application of capsaicin

The effect of increasing the total area of stimulation on the sensations of irritation produced by topical application of capsaicin was studied in two experiments. In the first experiment, stimulus area was varied by changing the size of filter paper disks on which capsaicin was delivered to the skin of the forearm. Subjects rated the intensity and quality of the cutaneous sensations over a 15-min period. Increasing stimulus area by a factor of 15 resulted in a relatively modest increase in the peak perceived intensity of irritation, a shortening of the latency to the onset of irritation, and shifts in the frequency of reports of sensations of itching and stinging/pricking. However, itch was the most frequently reported sensation regardless of stimulus size. In Experiment 2, stimulus area was manipulated by varying the number of stimuli applied to the skin. Despite a smaller difference in total stimulus areas (9-fold vs. 15-fold), the difference in perceived irritation was more pronounced than it was in Experiment 1 and reached statistical significance. It is therefore concluded that spatial summation does occur in the afferent system or systems responsible for the perception of capsaicin on the skin. This result is consistent with previous reports of summation at the threshold for heat pain and constitutes new information about the spatial integration of pruritic stimulation.     

Is blockade of conditioned flavor aversions by chlorpheniramine the result of state dependency?

Conditioned flavor aversions induced by pairing flavored fluids with ionizing irradiation, lithium chloride, estrogen, or centrifugal rotation have been blocked by prior administration of chlorpheniramine. The blockade may be due to state dependency. This possibility was evaluated in the present experiment, which assigned female Long-Evans rats to a factorial combination of chlorpheniramine (20 mg/kg) vs saline during training, centrifugal rotation (150 rpm for 15 min) vs none as an UCS, and chlorpheniramine vs saline in testing. Rats conditioned with saline and rotation showed strong aversions when tested with either same or chlorpheniramine. Rats conditioned with chlorpheniramine and rotation showed no change during conditioning; when tested with saline they showed no aversion, and when tested with chlorpheniramine they showed no change from conditioning. Rats conditioned with either chlorpheniramine or saline and no rotation showed high fluid intake when tested with saline and reduced fluid intake when tested with chlorpheniramine. The results were interpreted as offering little support for state dependency.     

First steps in family therapy: a personal construct analysis

This article describes the career of a small multi-disciplinary group undergoing a training in family therapy. It is a personal tale attempting to give the 'inside story' on the trainee's struggle to become an effective family therapist. The group's experience, both corporately and individually, is described using the theoretical framework and research methodology of Personal Construct Psychology.     

Turning the table on advice programs for parents: Using placemats to enhance family interaction at restaurants

There are many opportunities in a family's daily routine to enrich the interactions among its members. One such opportunity arises at family restaurants. Surveys of restaurant personnel and customers suggested the possibility of enriching family interactions by redesigning indigenous materials such as table placemats. Accordingly, we developed Table-Talk placemats that provided conversational topics and illustrated games in which the entire family could participate. After some testing of these placemats in a preschool, a field experiment was conducted with families dining in restaurants. Table-Talk placements occasioned more social and educational dialogue among family members than either traditional-placemat or no-material conditions. Social validation ratings provided by mental health counselors and the parents suggested that Table-Talk placemats occasioned healthy and enjoyable interactions among family members.     

The response ratio hypothesis for magnitude estimation

Assume that each presentation of a signal produces two independent random variable representations and that the ratio of responses on successive trials of a magnitude estimation experiment are proportional to the ratio of a representation from the present trial, which representation is then lost, to the remaining one from the previous trial. The mean response to a particular signal depends on the mean of the representation used, but in general exhibits drift over trials and sequential effects due to the preceeding trial; the mean response ratio does not exhibit drift, but it has a simple form only when there are no sequential effects; however, a modified mean ratio function has a simple form. A model suggested by D. V. Cross is a special case of this one. Simple timing and counting models for the representations fail to exhibit sequential effects, contrary to considerable data. However, data of the authors have suggested a version of the timing model in which the sample size of the representation varies by an order of magnitude depending on how close the signal is to the preceding one; this hypothesis accounts for the observed sequential effects and other aspects of the data.
