“Communicative work directed to transforming an individual's total identity into an identity lower in the group's social types is called a ‘status degradation ceremony'” (Garfinkel 1956, p. 420). Status degradation ceremonies are particularly troublesome for undercover narcotics agents. In this context, they act as the mechanism by which agents’ dissembled identities are questioned and their real police ones revealed. This process, what officers call “getting narced,” is the topic of the present paper. Explored here are both its causes and the responses officers proffer to neutralize full identity exposure. Causes are tactical in nature and involve transactional overaggressiveness. Neutralization responses are dramaturgical in nature and involve sarcastic admission, evidential refutation, and belligerent denial/threatening retort. Discussion focuses on the conceptual implications of officers’ counteruncovering moves (Goffman 1969) as these relate to the sociology of accounts (Scott and Lyman 1968). Data were drawn from ethnographic interviews with 30 high school undercover officers operating out of a large U.S. city.  相似文献

Abstract

Three categories of instruments or methods have been used to assess family functioning: unstandardized measures of total family functioning; instruments which measure family subsystems or unitary processes; and standardized total family assessment procedures. Six methods, comprising the standardized total family functioning category, are reviewed and compared. It is concluded that methods of total family assessment are nearing the formation of a family systems paradigm, although the psychometric qualities of the instruments lag behind theoretical development. Recommendations are made for further development of procedures to assess family systems.  相似文献

Abstract

In working with couples and families, the occasional clinical use of mental imagery techniques can frequently promote therapeutic breakthroughs. When sessions focused on a couple's (family's) current communication problems reach a point where progress seems slow and laborious, a therapist can encourage the couple (parents and perhaps even older children) to try one or more imagery sessions to understand their interactional patterns within the context of their own developmental periods. This article describes how imagery can lead couples to new and more constructive perspectives on the meaning of their interactions.  相似文献

Previous simulation research has focused on evaluating the impact of analytic assumption violations on statistics related to the F test and associated p CALCULATED values. The present article evaluated the bias of classical estimates of practical significance (i.e., effect size sample estimators $ {\widehat{\eta}^2} $ , $ {\widehat{\varepsilon}^2} $ , and $ {\widehat{\omega}^2} $ ) in a one-way between-subjects univariate ANOVA when assumptions are violated. The simulation conditions modeled were selected on the basis of prior empirical research. Estimated (1) sampling error bias and (2) precision computed for each of the three effect size estimates for the 5,000 samples drawn for each of the 270 (5 parameter Cohen's d values × 3 group size ratios × 3 population distribution shapes × 3 variance ratios × 2 total ns) conditions were modeled for each of the k = 2, 3, and 4 group analyses. Our results corroborate the limited previous related research and suggest that $ {\widehat{\eta}^2} $ should not be used as an ANOVA effect size estimator, even though $ {\widehat{\eta}^2} $ is the only available choice in the menus in most commonly available software.  相似文献

Differential reinforcement of other behavior (DRO) was used to reduce aggression and other inappropriate actions in a 26-year-old man with moderate mental retardation employed at a vocational center. Initially high baseline levels of inappropriate behavior were reduced by implementing contingent praise and a sticker system used to earn points needed to gain access to social activities. The procedure was low cost, required minimal time and effort on the part of center staff, and made it possible for the client to remain employed at the vocational center.  相似文献

Three experiments investigated the conditions under which electrolytic lesions of the dorsolateral periaqueductal grey (dlPAG) facilitate conditioned defensive freezing in the rat ( Rattus norvegicus ). Experiment 1 found that dlPAG lesions placed before context-shock pairings facilitated conditioned defensive freezing with massed but not distributed shock. No such effect was found in Experiment 2, when the lesions were placed after context-shock pairings. Experiment 3 found that dlPAG lesions facilitated subsequent conditioning with massed but not a single shock. In addition, no differences in sensitivity to thermal or shock pain were evident in lesioned and unlesioned rats. Taken together, these results are consistent with the suggestion that dlPAG activation interferes with the processing of contextual cues during association formation.  相似文献

An experiment by McCann and Besner (1987) suggested that non-words that are homophonic with a high-frequency word (e.g. “keap”) are named in the same amount of time as non-words that are homophonic with a low-frequency word (e.g. “fome”), despite such pseudohomophones being faster to name than non-pseudohomophones (e.g. “feap”, “yome”). Such a result is a challenge to any model of lexical processing that places the word-frequency effect at the stage when the word is being selected from amongst all lexical entries. McCann and Besner propose a complex alternative account where frequency effects arise at a later stage of processing, a stage that is not involved in the naming of pseudohomophones. The purpose of the present study is to look for a frequency effect in the naming of pseudohomophones, controlling for orthographic factors that McCann and Besner ignored. The first experiment, using a homophone decision task, establishes a set of items that produce a clear frequency effect. These items are then used in a naming experiment which also reveals a clear frequency effect for those subjects who make use of a lexical route when pronouncing pseudohomophones. It is concluded from this that the complex model developed by McCann and Besner is unnecessary.  相似文献
