The influence of unionization on job satisfaction and work perceptions

Unionized and nonunionized processing employees were compared on their perceptions of job characteristics and different facets of satisfaction. In addition, the relationship between job characteristics and job satisfaction were compared for unionized and nonunionized samples. Jobs generally were not significantly different in relation to job challenge for the two groups, but nonunionized employees reported higher levels of some satisfaction measures. The correlations between job characteristics and job satisfaction were stronger in the unionized sample. Implications of the present results and suggestions for further research are discussed.This article is based on research presented at the meeting of the Industrial Relations Research Association at Chicago, December, 1987.The author would like to thank James Martin for his help on this project.     

Balashov on special relativity, coexistence, and temporal parts

Yuri Balashov has argued that endurantism isuntenable in the context of Minkowskispacetime. Balashov's argument runs through twomain theses concerning the relation ofcoexistence, or temporal co-location. (1)Coexistence must turn out to be an absolute or objective matter; and inMinkowski spacetime coexistence must begrounded in the relation of spacelikeseparation. (2) If endurantism is true, then(1) leads to absurd conclusions; but ifperdurantism is true, then (1) is harmless. Iobject to both theses. Against (1), I arguethat coexistence is better construed as beingrelative to a hyperplane of simultaneity.Against (2), I argue that the consequences of(1) given endurantism are no worse than theconsequences of (1) given perdurantism.     

Determining the significance of scale values from multidimensional scaling profile analysis using a resampling method

Although multidimensional scaling (MDS) profile analysis is widely used to study individual differences, there is no objective way to evaluate the statistical significance of the estimated scale values. In the present study, a resampling technique (bootstrapping) was used to construct confidence limits for scale values estimated from MDS profile analysis. These bootstrap confidence limits were used, in turn, to evaluate the significance of marker variables of the profiles. The results from analyses of both simulation data and real data suggest that the bootstrap method may be valid and may be used to evaluate hypotheses about the statistical significance of marker variables of MDS profiles.     

One nation under God? Yusuf al-Qaradawi’s changing Fiqh of citizenship in the light of the Islamic legal tradition

In the wake of the Arab Revolutions of 2011, countries in the Middle East are grappling with how Islamists might be included within a regime of democratic political pluralism and how their aspirations for an “Islamic state” could affect the citizenship status of non-Muslims. While Islamic jurisprudence on this issue has traditionally classified non-Muslims in Islamic society as protected peoples or dhimma, endowed with what the authors term “minority citizenship”, this article will examine how the transnational intellectual Wasa?iyya or Centrist movement, of which Sheikh Yusuf al-Qaradawi is the figurehead, have sought to develop a new fiqh of citizenship in which Muslims and non-Muslims have equal civil and political rights. This article will focus on Yusuf al-Qaradawi on the basis that his very recent shift in 2010 on the issue is yet to be studied in depth, as well as in view of the fact that the dilemma faced by reformist Islamic scholars—how to integrate modern concepts into a legal tradition while simultaneously arguing for that tradition’s continuing relevance and authority—is for him rendered particularly acute, given that this tradition is itself the very source of his own authority and relevance. It will therefore be argued that the legacy of the Islamic legal tradition structures his discourse in a very specific way, thereby having the potential to render it more persuasive to his audience, and worthy of a more detailed examination.     

The divergent effects of fear and disgust on unconscious inhibitory control

Previous studies have shown that negative emotional distracters impair conscious inhibitory control. Recent research has shown that inhibitory control can be triggered unconsciously; therefore, in Experiment 1, we aimed to investigate whether negative emotional distracters affect unconscious inhibitory control. Furthermore, in Experiment 2, we examined whether fearful and disgusting distracters have differential effects on unconscious inhibitory control. Participants were instructed to perform a masked Go/No-Go task superimposed on a negative or neutral image cue (Experiment 1) or on a fearful, disgusting or neutral image cue (Experiment 2). Results showed that negative emotional distracters impaired unconscious inhibitory control; furthermore, disgusting distracters impeded unconscious inhibitory control when compared to fearful ones. This study is the first to provide evidence that fear and disgust may affect unconscious inhibitory control differently. These results expand the understanding of the relationship between emotions and inhibitory control.     

Luminance affects age-related deficits in object detection: implications for computerized psychological assessments

As psychological instruments are converted for administration on computers, differences in luminance and contrast of these displays may affect performance. Specifically, high-luminance assessments may mask age-group differences that are apparent under lower luminance conditions. We examined the effects of luminance and contrast on object detection using computerized and naturalistic assessments. Younger and older adults displayed more differences in performance across differing contrast levels in conditions that were matched for luminance, despite the conditions appearing perceptually different. These findings indicate that computerized assessments should be created with luminance levels that are similar to those of the tasks they purport to simulate in order to enhance their validity.
