Training time estimation to improve alarm reactions

Prior researchers have demonstrated that training may be an effective strategy for improving operator reactions to alarm systems with less than perfect reliability. Of the training strategies tested, recognition of temporal patterns in prior sensor activations seems to offer the greatest promise for improving the speed and appropriateness of subsequent alarm reactions. The current research was completed to clarify which of three temporal interval training methods leads to the most appropriate alarm reactions. Fifty-six undergraduates evaluated whether alarms occurring after sensor activations were true or false, based on elapsed time between the sensor signals and the alarm signals. Participants completed five training sessions to learn to estimate time intervals using simple repetition training, performance feedback, or performance feedback plus subdivision cues. Contrary to expectations, results indicated that participants did not benefit differentially from temporal interval training. Differences between pre- and posttest interval estimation performance was similar among groups, and training groups performed comparably when reacting to signals. Participants generally focused on advertised alarm system reliability, responding more appropriately and more quickly to lower reliability alarms. Future researchers and designers should replicate these findings with realistic tasks and real-world complex task operators to determine their generalization.     

Foreign Wars and Domestic Prejudice: How Media Exposure to the Israeli‐Palestinian Conflict Predicts Ethnic Stereotyping by Jewish and Arab American Adolescents

This study was based on the theory that adolescents view scenes of violent ethnic conflicts in the mass media through the lens of their own ethnicity, and that the resulting social‐cognitive reactions influence their negative stereotypes about similar ethnic groups in their own country. We interviewed 89 Jewish and 180 Arab American high school students about their exposure to the Israeli‐Palestinian conflict, their social cognitive reactions to it, and their stereotypes toward ethnic groups. Beyond the effects of ethnic identity, the degree to which adolescents identified with Israelis and Palestinians in the media was a key variable linking exposure to media depictions of the conflict and the implicit ethnic stereotypes they displayed about Jewish Americans and Arab Americans.     

Community and Individual Factors Associated with Cigarette Smoking Among Young Men Who Have Sex With Men

Young men who have sex with men (YMSM) have higher rates of cigarette smoking than their heterosexual counterparts, yet few studies have examined factors associated with cigarette smoking among YMSM. The present study sought to understand how different types of gay community connection (i.e., gay community identification and involvement, gay bar/club attendance) were associated with smoking among YMSM recruited through venue-based sampling in Los Angeles, California (N = 526). Structural equation modeling was used to isolate direct and indirect effects of gay community connection on smoking through cognitive and psychological mediators (i.e., psychological distress, health values, internalized homophobia). Findings indicate YMSM cigarette smoking prevention and intervention must be tailored to address the direct and indirect influences of the gay community.     

Structure of National Perceptions of Social Needs Across EU Countries

Back in 1975, the European Union (EU) Council of Ministers defined the poor as “individuals or families whose resources are so small as to exclude them from the minimum acceptable way of life of the Member State in which they live”. This widely quoted definition leaves room for discussion about what can be considered a “minimum acceptable way of life” in different countries and thus also whether national perceptions of minimum standards vary from one country to the next. The paper explores this latter issue by exploiting the first EU dataset allowing a comparative analysis of the items which citizens in the different Member States consider to be necessary for people to have an “acceptable” standard of living in the country where they live. It assesses the (in)variance of the structure of the perception of social needs between countries on the basis of an extension of the multidimensional scaling (MDS) method, and shows a high level of congruence between the 27 national patterns. An important consequence of this result is that it supports the approach which consists of measuring deprivation on the basis of a same set of (validated) items across all the Member States.     

Games,Pastimes, and Leisure Pursuits

In studies ranging from oracular practices and court proceedings to alternative philosophies, reality disjunctures, and a family’s work in maintaining the normality of a severely retarded child, Mel Pollner put together something like a cabinet of curiosities exhibiting the social character of reasoning’s worldly enterprises. At the same time, he felt that ethnomethodology—and, in particular, ethnomethodological studies of work—had taken a wrong direction, turning away from disciplinary sociology’s sociological project. This paper, by examining the play of bridge, soccer, checkers, and chess, reconsiders this position and illustrates some of the peculiarities of a sociology of the witnessable social order.     

Multiple forms of perceived discrimination and health among adolescents and young adults

Research on perceived discrimination has overwhelmingly focused on one form of discrimination, especially race discrimination, in isolation from other forms. The present article uses data from the Black Youth Culture Survey, a nationally representative, racially and ethnically diverse sample of 1,052 adolescents and young adults to investigate the prevalence, distribution, and mental and physical health consequences of multiple forms of perceived discrimination. The findings suggest that disadvantaged groups, especially multiply disadvantaged youth, face greater exposure to multiple forms of discrimination than their more privileged counterparts. The experience of multiple forms of discrimination is associated with worse mental and physical health above the effect of only one form and contributes to the relationship between multiple disadvantaged statuses and health. These findings suggest that past research may misspecify the discrimination-health relationship and fails to account for the disproportionate exposure to discrimination faced by multiply disadvantaged individuals.

BEYOND THE CLINIC: IN-HOME THERAPY WITH HEAD START FAMILIES

Social workers and case managers have provided in-home services to families for some time. The field of Marriage and Family Therapy, however, has begun to do in-home work only recently. This paper describes the experiences of MFT interns who worked with families in their homes. Two university graduate MFT training programs conceptualized and practiced in-home therapy with families who had at least one child enrolled in the local Head Start program. This collaborative effort was part of the AAMFT-Head Start Training Partnership Project that had the goal of funding projects that demonstrated successful partnerships between MFT and Head Start. Six interns worked with 27 Head Start families in their homes. A model of the interns' transition from clinic-based to home-based therapy is discussed and applied to working with Head Start families. The framework of in-home therapy is expanded to conceptualizing larger systems and community-based interventions, and recommendations for family therapists in private practice and agency settings are made.     

Beliefs About Cues to Deception: Mindless Stereotypes or Untapped Wisdom?

In this longitudinal study, senders told truths and lies to same-sex friends (judges) at both one month and six months into the relationship. Judges guessed whether the stories were truths or lies, and described the cues they used to make their decisions. These cues were coded into categories according to the nature of the cue (verbal, visual, or paralinguistic). Judges mentioned more verbal cues when the story was truthful than when it was fabricated, and mentioned more visual nonverbal cues when it was fabricated than when it was truthful. Therefore, perceivers' stated beliefs about cues discriminated the truths from the lies, although their explicit judgments of deceptiveness did not. Perceivers who mentioned visual or verbal cues more often were not more accurate at detecting deception (explicitly), but those who mentioned paralinguistic cues more often were more accurate.
