Problems facing public housing authorities can be addressed through two basic alternative perspectives. One assumes that difficulties result from the behavior of certain “problem” tenants and recommends careful screening of applicants. This perspective influenced a housing authority in a small city, which desired a means to select tenants who would be less likely to exhibit problems. Information in the records of the housing authority was analyzed to identify tenant characteristics predictive of problem tenancy. The findings indicated that these problems were not as widespread as believed by management and that tenant characteristics were not strongly predictive of problems. Application of this approach would probably not constitute a significant improvement over present practices and might allow unfair discrimination to occur unwittingly. Instead, the most feasible strategy to reduce the impact of problem tenancy, even within a single locale, seems to be to focus on management practices and to address the more fundamental causes of tenant difficulties.  相似文献

A programmable sine-wave generator has been developed that permits microcomputer control of both discrete and continuous variations in the frequency and amplitude of auditory, visual, or vibrotactile stimuli. The function and design of the sine-wave generator as a peripheral to the Apple II/FIRST system are detailed. Moreover, adaptations of the basic sine-wave circuit are briefly described for interfacing it with other microcomputers (e.g., the IBM PC and compatibles), and for altering the waveform, range, and resolution of the output. Sample programs in Apple II/FIRST and Applesoft BASIC for controlling signal frequency and amplitude are used to illustrate the simplicity of programmable control. The sine-wave generator has many of the capabilities of commercially available ones, at a fraction of the cost.  相似文献

The present study is an attempt to investigate how sex of parent, parenting experience, and child's gender influence parents' reactions to risky and annoying behaviors of children. The subjects were 15 sets of expectant parents and 16 sets of parents from each of three other family configurations (one boy, one girl, or both a boy and a girl). The subjects viewed a 23-minute videotape composed of 22 videoclips. Each videoclip depicted a common activity for a 12- to-36-month-old child that could elicit parental intervention because of risk or annoyance or both. Fifteen scenes were acted by children who had been previously rated as gender ambiguous in appearance. The audio portion of the tape identified each genderambiguous child as a boy to some subjects and as a girl to others. The subjects were instructed to press buttons to indicate when they would respond and the types of response (physical or verbal) they would make. Analyses showed strong effects of parenting experience for latency and number of interventions. Generally, parents of one boy intervened most quickly, followed by parents of two children, parents of one girl, and expectant parents. The gender label manipulation showed effects only on the high risk tapes. Mothers responded more than fathers in situations that were annoying but not risky. Mothers and fathers agreed when children were engaged in risky behaviors. The use of videoclips to study parent socialization is a useful supplement to observations and self-report questionnaires.Preparation of the gender labeling tasks was supported in part by BRSG Grant 50 7RR07080 awarded by the Biomedical Research Support Program, Division of Research Resources, National Institutes of Health. Part of the article is based on the doctoral dissertation of the first author, presented to the Department of Psychology, University of Oregon. Data analyses and preparation of the article were completed while the third author was on a postdoctoral fellowship (Grant 1 T32 MH 16955-01) through the Oregon Social Learning Center.  相似文献

To learn whether criticism and regulation of research practices have been followed by a reduction of deception or use of more acceptable approaches to deception, the contents of all 1969, 1978, 1986, and 1992 issues of the Journal of Personality and Social Psychology were examined. Deception research was coded according to type of (non)informing (e.g., false informing, consent to deception, no informing), possible harmfulness of deception employed (e.g., powerfulness of induction, morality of the behavior induced, privacy of behavior), method of deception (e.g., bogus device or role, false purpose of study, false feedback), and debriefing employed. Use of confederates has been partly replaced by uses of computers. "Consent" with false informing declined after 1969, then rose in 1992. Changes in the topics studied (e.g., attribution, socialization, personality) largely accounted for the decline in deception in 1978 and 1986. More attention needs to be given to ways of respecting subjects' autonomy, to appropriate debriefing and desensitizing, and to selecting the most valid and least objectionable deception methods.  相似文献

Hurricane Andrew: Psychological distress among shelter victims   总被引:1,自引:0,他引:1  
This study examined psychological distress and functioning among Hurricane Andrew victims who lost their homes and were living in shelters. Four and one-half weeks after Hurricane Andrew struck southern Florida, 89 (45 males, 44 females) Blacks, Hispanics, and Whites completed a questionnaire. The questionnaire asked for information about psychological and psychophysiological symptoms, use of mental health services, coping responses, and extent of preparation for the storm. The findings suggest that loss of home and property were related to distress and depression. About one-quarter of the sample were moderately depressed. Over one-third of the sample reported experiencing psychological and psychophysiological distress. Approximately one-half of the subjects did not take the hurricane warnings seriously. White subjects began preparing earlier for the storm, and evacuated their homes more frequently than did Black subjects. Implications of the findings and future research directions are discussed.  相似文献

The present study evaluated the factor structure and psychometric properties of the Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996) in the nonclinical sample of 230 young adults. The BDI-II is a revised version of the BDI-IA. We evaluated the fit of three alternative models to the sample data, using confirmatory factor analysis. Results provided support for the fit of the oblique three-factor model. The BDI-II and factor scales had satisfactory coefficient alpha indices. We obtained gender differences on the BDI-II item, total, and factor scale scores. We examined the relations of the BDI-II with demographic variables and with other self-report measures of social desirability, anxiety, depression, stress, and self-esteem. We also examined the issue of whether specific self-report measures of anxiety and depression assess separate or different constructs. We discuss the limitations of the present study.  相似文献

The effects of background visual roll stimulation on postural control, manual controlf andselfmotion perception were investigated in this study. In the main experiment, 8 subjects were exposed to wide field-of-view background scenes that were tilted and static, continuously rotating, or sinusoidally rotating at frequencies between 0.03 and 0.50 Hz, as well as a baseline condition. The subjects performed either a postural control task (maintain an upright stance) or a manual control task (keep an unstable central display horizontally level). Root-mean square (RMS) error in both the postural and manual control tasks was low in the static tilt condition and extremely high in response to continuous rotation. Although the phases of the postural and manual responses were highly similar, the power and RMS error generated by the sinusoidal visual background stimulation peaked at a lower frequency in the postural task. Vection ratings recorded at the end of the postural and manual trials somewhat paralleled tbafrequency tuning differences between tasks, which a subsequent experiment showed to be the result of the differential motion of the central display rather than the differential positioning of the subject. In general, these results show that the dynamic characteristics of visual orientation systems vary according to the specific motor and/or perceptual system investigated.  相似文献

Children are exposed to differences in adult interactive styles from an early age. The Ainsworth Strange Situation. designed as a standard measure to activate attachment behaviors in the young child, allows us to examine the child's reaction to individual differences in strangers' styles. In the present study, the effect of 11 different strangers was examined to determine if different stranger styles influenced the scoring of behavioral ratings of the child's behavior in the Strange Situation. Boys and girls reacted differently to the different strangers. Eighteen-month-old children showed more variations in their reactions to different interactional styles than did 12-month-olds. Boys showed more resistance and avoidance to strangers who used more direction and initiation. Girls did not react this way. The results are discussed in terms of the child's expectations of sex-determined styles of interaction learned from past social interactions.This research was supported by Grant MH 37911 to the senior author from the Behavioral Sciences Research Branch, Family Processes Division, NIMH, U.S. PHS and Grant HD 17571 from the National Institute of Child Health and Development.  相似文献
