A meta-analysis and conceptual critique of research on role ambiguity and role conflict in work settings

Although role ambiguity and role conflict have been studied extensively in the organizational sciences, there remain numerous empirical discrepancies among the reported research results. Consequently, disagreement exists as to what can be concluded about the role ambiguity and role conflict research. Coupled with this empirical impasse has been a persistent and relatively singular approach to conceptually studying role ambiguity and role conflict. In response to this empirical and conceptual situation, a meta-analysis and a conceptual reevaluation of the role ambiguity and role conflict research were performed. Using the Hunter, Schmidt, and Jackson (1982, Meta-analysis: Cumulating research findings across studies, Beverly Hills, CA: Sage) meta-analysis procedures, this study analyzed 29 correlates of role ambiguity and role conflict. These correlates include ten organizational context variables, five individual characteristics, ten affective reactions, and four behavioral reactions. Meta-analysis procedures were used to measure the strength and consistency of the relationship found between each of the 29 correlates and role ambiguity and role conflict. Meta-analysis was also used to determine where moderator variables should play a critical part in future role ambiguity and role conflict research. Based on the results of the meta-analysis, several empirical summaries and conclusions are presented. Along with these, several conceptual observations and reconceptualizing suggestions are offered. It is concluded that while a great deal is known about role ambiguity and role conflict in the organizational sciences much remains to be learned.     

A simple,inexpensive stimulus waveform generator

A simple circuit for a sine wave generator is described. The total cost for construction is approximately $30.00. At present, the unit is used to generate a sinusoidally modulated light stimulus for steady state visual evoked response experiments. Modifications of the circuit for other applications are discussed.     

RECONCEPTUALIZING ISSUES THAT AFFECT WOMEN'S SEXUAL DECISION-MAKING AND SEXUAL FUNCTIONING

This paper addresses five existing societal myths and their underlying faulty assumptions about women's sexuality. The following myths are examined: (a) women possess adequate sexual knowledge to understand their sexual needs, (b) they know how to communicate about sex, (c) they engage in sex because they want to do so, (d) if they are sexually active, they enjoy sex, and (e) they use their knowledge of sex to protect themselves from sexually transmitted diseases and pregnancy. These myths need to be considered when conducting research and developing interventions designed to decrease women's sexual risk-taking. Research that assesses women's levels of factual sexual knowledge, comfort and skills discussing sexual information, and literacy is needed. The importance of examining ethnic, cultural, economic, religious, relationship factors, and psychological issues is discussed in order to encourage research relevant to women's sexual decision-making.     

Slurs,roles and power

Slurring is a kind of hate speech that has various effects. Notable among these is variable offence. Slurs vary in offence across words, uses, and the reactions of audience members. Patterns of offence aren’t adequately explained by current theories. We propose an explanation based on the unjust power imbalance that a slur seeks to achieve. Our starting observation is that in discourse participants take on discourse roles. These are typically inherited from social roles, but only exist during a discourse. A slurring act is a speech-act that alters the discourse roles of the target and speaker. By assigning discourse roles the speaker unjustly changes the power balance in the dialogue. This has a variety of effects on the target and audience. We show how these notions explain all three types of offence variation. We also briefly sketch how a role and power theory can help explain silencing and appropriation. Explanatory power lies in the fact that offence is correlated with the perceived unjustness of the power imbalance created.     

Using computer‐assisted instruction to increase the eye gaze of children with autism

Many children diagnosed with autism spectrum disorders have difficulty making appropriate eye contact and engaging in joint attention. The current study evaluated a computer‐assisted instruction package (pairing visual stimuli with vocal stimuli) as a novel treatment to improve the eye gaze accuracy in 3 elementary school children with autism. The researchers measured the latency from a recorded verbal stimulus to the students making eye contact with pictures of familiar individuals displayed on a computer screen, and the duration for which eye gaze on the stimulus was maintained. An automated infrared camera system for measuring eye gaze was utilized that eliminated the need for an instructor to make subjective judgments regarding participants' eye gaze. For all three participants, duration of eye contact increased, and latency to responding decreased following exposure to the computer‐assisted instruction. The implications of these findings for the treatment of individuals with autism are discussed, along with suggestions for future research on the topic.     

Forensic psychology and Islamic jurisprudence

Islamic jurisprudence is the most widely used system of religious law in the world today. However, how forensic psychology may operate within this system has been largely unexplored. The current review sets out to explore the relationship between Islamic jurisprudence and forensic psychology by examining the Islamic legal concepts of evidence, competence, insanity, psychological disorder and intellectual disability and their implications for forensic practice. Also discussed are the potential barriers to forensic psychological practice in countries using a system of Islamic law.     

Mozambican immigrants to South Africa: Their xenophobia and discrimination experiences

We explored Mozambican immigrants’ lived experiences of xenophobia and discrimination in South Africa. Informants were 15 Mozambican immigrants (female = 7, male = 8) living in an informal settlement in Zandspruit, Gauteng Province. They completed open-ended written narratives on xenophobic and discriminatory experiences. Following thematic analysis, we identified three themes to characterise the Mozambican immigrants’ experiences of xenophobia and discrimination: (i) abusive attitudes, (ii) ethnic discrimination, and (iii) scapegoating. The Mozambican immigrants’ experiences of xenophobia and discrimination are consistent with findings from the extant international literature on ingroup/outgroup social strife with real or perceived scarcity of resources.
