A comparison of situational and dispositional predictors of perceptions of organizational politics

The present study is an investigation of situational and dispositional characteristics that may predispose an employee to perceive his or her organization as political. Participants were 501 regular members, civilian members, and public servants of the Royal Canadian Mounted Police. Measures used for this research were the Formalization Scale (G. R. Oldham & J. R. Hackman, 1981), the Job Autonomy Scale (H. P. Sims, A. D. Szilagyi, & R. T. Keller, 1976), the Mach IV (A. Zook & G. J. Sipps, 1986), the Dominance subscale from the Manifest Needs Questionnaire (R. M. Steers & D. N. Braunstein, 1976), the Survey of Organizational Climate (J. C. Taylor & D. G. Bowers, 1972), the Perceptions of Organizational Politics Scale (G. R. Ferris & K. M. Kacmar, 1992), and the Work Locus of Control Scale (P. E. Spector, 1988). Results indicated that organizational climate, formalization, work locus of control (both internal and external measures), and Machiavellianism were significant predictors, accounting for 52% of the variance in participants' perceptions of organizational politics. Limitations of the present study and directions for future research are outlined.     

Interpretations of voices in patients with hallucinations and non-patient controls: a comparison and predictors of distress in patients

BACKGROUND: This study tested the hypotheses that interpretations of voices will be associated with distress linked to auditory hallucinations, and that patients experiencing hallucinations will exhibit higher levels of negative interpretations in comparison with non-patients. METHOD: The Interpretation of Voices Inventory (British Journal of Clinical Psychology 41 (2002) 259) was administered to patients who met DSM-IV criteria for schizophrenia spectrum disorders with auditory hallucinations and non-patients. Patients were also assessed using a semi-structured interview to asses clinical dimensions of their voices. RESULTS: The results showed that people with psychosis who experience auditory hallucinations did exhibit higher levels of positive and negative interpretations of voices, in comparison to non-patients. Correlational analyses revealed that interpretations of voices were significantly associated with emotional, physical and cognitive characteristics of voices. Regression analyses demonstrated that physical characteristics of voices and metaphysical beliefs were significant predictors of emotional characteristics of voices. CONCLUSIONS: The theoretical and clinical implications of these findings are discussed.     

Scientific Understanding and Mathematical Abstraction

This paper argues for two related theses. The first is that mathematical abstraction can play an important role in shaping the way we think about and hence understand certain phenomena, an enterprise that extends well beyond simply representing those phenomena for the purpose of calculating/predicting their behaviour. The second is that much of our contemporary understanding and interpretation of natural selection has resulted from the way it has been described in the context of statistics and mathematics. I argue for these claims by tracing attempts to understand the basis of natural selection from its early formulation as a statistical theory to its later development by R.A. Fisher, one of the founders of modern population genetics. Not only did these developments put natural selection of a firm theoretical foundation but its mathematization changed the way it was understood as a biological process. Instead of simply clarifying its status, mathematical techniques were responsible for redefining or reconceptualising selection. As a corollary I show how a highly idealised mathematical law that seemingly fails to describe any concrete system can nevertheless contain a great deal of accurate information that can enhance our understanding far beyond simply predictive capabilities.

Role of gamma-band synchronization in priming of form discrimination for multiobject displays

Previous research has shown that synchronized flicker can facilitate detection of a single Kanizsa square. The present study investigated the role of temporally structured priming in discrimination tasks involving perceptual relations between multiple Kanizsa-type figures. Results indicate that visual information presented as temporally structured flicker in the gamma band can modulate the perception of multiple objects in a subsequent display. For judgments of both relative orientation and relative position of 2 rectangles, response time to identify and discriminate relations between the objects was consistently decreased when the vertices corresponding to distinct Kanizsa-type rectangles were primed asynchronously. Implications are discussed for models of the perception of objects and their interrelations.     

A preliminary study into stress in palliative care: optimism, self-efficacy and social support

Caring for the terminally ill is a demanding, but rewarding area of health care. Stressors unique to this working environment--dealing with patient death rather than cure, and supporting entire family units, for example--put caregivers at risk from stress related illness. This study investigated the buffering effects of optimism, self-efficacy and social support against two measures of stress within the palliative setting. Comparisons were made between volunteer (n = 18) and professional (n = 18) caregivers across three caregiving settings. Data were collected retrospectively about personal control variables; use of and satisfaction with, social support; and, perceived general and occupational specific stress levels. Differences in reported stress levels were found both between settings (NHS, hospice and community-based) and between caregiver type (salary status and occupational category). Optimism was more strongly and consistently associated with low levels of perceived stress than was self-efficacy. Satisfaction with social support was highest among paid workers, and in terms of buffering stress in the whole sample, appeared mediated by optimism. Worksite interventions targeting caregiver self-efficacy and optimism are recommended as a potential source of stress management within this population.     

Gender-Role Congruence and Self-Referencing as Determinants of Advertising Effectiveness

In an initial experiment, men and women with varied gender-role orientations evaluated gender-stereotyped and nonstereotyped advertisements for gendered products that are actually used by both sexes. Consistent with a gender-role congruence model of advertising effectiveness, traditional participants (masculine men; feminine women) responded more favorably to traditional (i.e., gender-stereotyped) than to nontraditional advertisements, whereas nontraditional participants (androgynous individuals; feminine men; masculine women) reacted somewhat more favorably to the nontraditional advertisements. Experiment 2 revealed that when encouraged to self reference, traditional participants became much more responsive to nontraditional advertisements, even more so than were the nontraditional participants. Practical implications of these results are discussed.     

Academic growth curve trajectories from 1st grade to 12th grade: effects of multiple social risk factors and preschool child factors

This study examined the main and interactive effects of multiple social risk factors and the preschool child factors of IQ and mental health on students' academic trajectories from 1st grade to 12th grade. A multiple risk score summarizing 10 environmental risk factors was calculated at 4 years of age for 145 families. Hierarchical linear modeling showed that high-risk students had lower grades and more absences from 1st grade to 12th grade than did low-risk students. Significant interactions between risk and child factors for students' grade point average (GPA) revealed that child factors had significant effects only for low-risk students. Higher IQ and better mental health improved the GPA trajectories of low-risk children but did not influence the GPA trajectories of high-risk children.     

Racial differences in self-disclosure of suicidal ideation and reasons for living: implications for training

Racial differences in suicidal self-disclosure and reasons for living were investigated in 2 separate studies. In Study 1, a random sample of archival client and therapist intake data from a university counseling center for 1 year was examined, and results indicate that ethnic minority clients do not self-disclose suicidal ideation as readily as their nonethnic minority peers. In addition, a significantly higher number of ethnic minority clients were deemed "hidden ideators" because their suicidal ideation only became evident when a counselor performed a suicide risk assessment. Only 1 of the 36 ethnic minority clients with suicidal ideation in the sample voluntarily self-disclosed this ideation at intake without an assessment by the therapist. Study 2 used the Reasons for Living Inventory (RFL) and compared African American and European American college students from an introductory psychology course. The RFL is a useful instrument to compare potential race differences in reasons people report for choosing not to kill themselves, because it does not require respondents to self-disclose (or to have) current suicidal ideation. The results from Study 2 indicate European Americans report fewer reasons for choosing not to kill themselves than their African American peers and that African Americans scored significantly higher than European Americans on the moral objections and survival and coping beliefs subscales of the RFL. Implications for training counselors in suicide risk assessment, prevention, and treatment with ethnic minorities are discussed.     

Psychometric properties of the Self-Perception Profile for Children in a biracial cohort of adolescent girls: the NHLBI Growth and Health Study

The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is an epidemiologic study of 1,213 Black and 1,166 White girls (ages 9-10) of risk factors for obesity. NGHS used Harter's Self-Perception Profile for Children (SPPC) to measure domain-specific competence and overall self-worth. This report reviews the psychometric properties of the SPPC in this biracial cohort at baseline and Year 3 visits (ages 11-12). Simple structure yielding unique components for each of the SPPC domains was obtained for White but not Black girls, whether analyzed overall or by parental education level. Internal consistency was higher for White girls in both years. The lack of simple structure was reflected in the higher correlations among the subscales for Black girls. The structure and internal consistency improved in Year 3 for Black girls, indicating that the physical appearance and athletic competence domains were not yet fully differentiated at baseline. Readers should be cautious, however, when interpreting the SPPC in young Black girls.
