Sex differences in unfamiliar face identification: evidence from matching tasks

Research on sex differences in face recognition has reported mixed results, on balance suggesting an advantage for female observers. However, it is not clear whether this advantage is specific to face processing or reflects a more general superiority effect in episodic memory. The current study therefore examined sex differences with a face-matching task that eliminates memory demands. Across two experiments, female but not male observers showed an own-sex advantage on match trials, in which two pictures have to be identified as the same person. This advantage was present for whole faces and when only the internal or external facial features were shown. Female observers were also more accurate in these three conditions on mismatch encounters, in which two photographs have to be identified as different people, but this reflects a more general effect that is present for male and female faces. These findings converge with claims of a female advantage in face recognition and demonstrate that this effect persists when memory demands are eliminated.     

The theory of multiple stupidities: education,technology and organisation in Arabia

Traditional perspectives have envisaged intelligence as one entity dominated by a single set of abilities (i.e. cognitive abilities), whereas modern perspectives have defined intelligence in various shapes (e.g. linguistic, musical and interpersonal intelligences). By the same token, traditional perspectives have examined stupidity as one set of inabilities (i.e. cognitive inabilities). However, it is not clear whether modern perspectives have discussed whether stupidity exists in various forms—in the same way as they have envisaged intelligence. To address this limitation, 257 university members were asked to share what they perceived as being stupid educational and technological practices in their institutions. Analysis of the data suggested three concepts were important to the members: moral, spatial and administrative stupidities. That is, stupidity is perceived to come in the form of failing to meet certain moral, spatial and administrative values. This implies that modern perspectives may conceptualise stupidity differently from traditional perspectives, seeing it as going beyond cognitive inabilities and viewing it as existing in various forms (e.g. moral, spatial and administrative stupidities). Thus, there are multiple stupidities as there are multiple forms of intelligence. A strength of this research is that it views stupidity through an organisational and qualitative lens, although some may traditionally expect such a topic to be examined quantitatively through psychometric and biological approaches.     

Continuance commitment and turnover: Examining the moderating role of negative affectivity and risk aversion

This paper examines the moderating role of negative affectivity and risk aversion in the relationships of two bases of continuance organizational commitment (continuance–sacrifices and continuance–alternatives) to turnover, within a stress–coping perspective. More specifically, we propose that (a) the perspective of leaving is a source of stress for those who stay due to the fear of losing valued advantages (i.e. high continuance–sacrifices commitment) and (b) staying is perceived to be stressful by individuals who remain based on a lack of employment alternatives (i.e. high continuance–alternatives commitment). We argue that these perceptions are magnified by negative affectivity and risk aversion, resulting in individuals who present these traits to use avoidance–withdrawal strategies in coping with these situations. Accordingly, based on a sample of 509 human resource management professionals, we found (a) negative affectivity and risk aversion to strengthen the negative relationship of continuance–sacrifices commitment to turnover and (b) continuance–alternatives commitment to relate positively to turnover among individuals with high negative affectivity. We discuss the implications of these findings for our understanding of how commitment mindsets and personality traits affect turnover decisions.     

Rorschach variables related to blood glucose control in insulin-dependent diabetes patients

In this article, we explored relations between selected Rorschach variables and blood glucose control in Insulin-Dependent Diabetes Mellitus (IDDM) patients. Three domains of psychological functioning are taken into consideration: emotional distress, coping and problem solving, and cognitive efficiency. Seventy-one IDDM patients (38 men, 33 women; mean age 42.2 +/- 14.9 years) from an outpatient unit took the Rorschach Comprehensive System (Exner, 1986). Nine variables were selected as independent variables. Blood glucose, a dependent variable, was measured by the proportion of glycated hemoglobin. Results of 2 regression analyses show that Y and C' correlate to higher blood glucose. WSum C and the absence of texture related to lower levels of blood glucose. A confounding effect of complications was observed. The findings suggest that emotional factors should be accorded greater attention in behavioral self-regulations in diabetes.     

Martin's Axiom,Omitting Types,and Complete Representations in Algebraic Logic

We give a new characterization of the class of completely representable cylindric algebras of dimension 2 #lt; n w via special neat embeddings. We prove an independence result connecting cylindric algebra to Martin's axiom. Finally we apply our results to finite-variable first order logic showing that Henkin and Orey's omitting types theorem fails for L _n, the first order logic restricted to the first n variables when 2 #lt; n#lt;w. L _n has been recently (and quite extensively) studied as a many-dimensional modal logic.     

Correlates of an ego-grasping attitude in Kuwaiti and American students

In samples of American and Kuwaiti students, scores on an ego-grasping scale were associated with measures of psychopathology, the latter more strongly associated with ego-grasping scores for the American than the Kuwaiti sample.     

The Kuwait University Anxiety Scale: results for 9,031 Saudi students

The Kuwait University Anxiety Scale was administered to 9,031 male (n = 4,143) and female (n = 4,888) Saudis. They were students in secondary schools (n = 4.793) and university undergraduates (n = 4,238) recruited from scattered geographical regions of the Kingdom of Saudi Arabia. Ages ranged from 15 to 26 years, mean age 19.5 yr. (SD = 2.8). The scale displayed good alphas (from .85 to .88), retest reliability (from .94 to .95), as well as good criterion-related validity (from .63 to .73) against the Trait subscale of the State-Trait Anxiety Inventory. Three highly loaded factors were extracted: Cognitive/Affective, Subjective, and Somatic anxiety. Sex differences overshadow age differences as sex-related differences were significant between the age groups from 16 to 25 years, i.e., females attained higher mean scores than their male peers. Saudi students attained means similar to those of Kuwaiti students, but both groups have significantly higher mean scores than American and Spanish college students. By and large, the scale can be recommended for use in research among students in the Saudi context.     

On Neat Reducts of Algebras of Logic

SC , CA , QA and QEA stand for the classes of Pinter's substitution algebras, Tarski's cylindric algebras, Halmos' quasipolyadic algebras, and quasipolyadic equality algebras of dimension , respectively. Generalizing a result of Németi on cylindric algebras, we show that for K {SC, CA, QA, QEA} and ordinals < , the class Nr K of -dimensional neat reducts of -dimensional K algebras, though closed under taking homomorphic images and products, is not closed under forming subalgebras (i.e. is not a variety) if and only if > 1.From this it easily follows that for 1 < < , the operation of forming -neat reducts of algebras in K does not commute with forming subalgebras, a notion to be made precise.We give a contrasting result concerning Halmos' polyadic algebras (with and without equality). For such algebras, we show that the class of infinite dimensional neat reducts forms a variety.We comment on the status of the property of neat reducts commuting with forming subalgebras for various reducts of polyadic algebras that are also expansions of cylindric-like algebras. We try to draw a borderline between reducts that have this property and reducts that do not.Following research initiated by Pigozzi, we also emphasize the strong tie that links the (apparently non-related) property of neat reducts commuting with forming subalgebras with proving amalgamation results in cylindric-like algebras of relations. We show that, like amalgamation, neat reducts commuting with forming subalgebras is another algebraic expression of definability and, accordingly, is also strongly related to the well-known metalogical properties of Craig, Beth and Robinson in the corresponding logics.     

When do low‐power customers complain? The joint effects of chronic sense of personal power and complaint success on complaining intentions

In the customer complaint literature, researchers have found that the lack of an incidental sense of power is one of the reasons why customers do not complain. However, two issues are left unanswered: does a chronic sense of power influence consumer complaining behavior, and how individuals who feel chronically powerless can be encouraged to complain when dissatisfied. The present study is intended to address this topic. Drawing on the approach–inhibition theory of power, we argue that the probability of complaint success increases the complaint behavior of customers with a low chronic sense of power, thereby mitigating the differences in the complaint behavior of consumers with low and high power. The three studies indicated that a low chronic power was negatively associated with complaining intentions and that this association was mitigated by the perceived success of complaining.     

Ethical leadership and organizational citizenship behaviours: the moderating role of organizational identification

This study examines whether the relationship between ethical leadership and organizational citizenship behaviours (OCBs) is contingent on organizational identification. Drawing on substitutes for leadership theory, the study proposes that the relationship between ethical leadership and OCBs will be attenuated when employees strongly identify with their organization. Using a sample of Egyptian banking sector employees, this proposition was tested with hierarchal linear modelling (HLM). The results revealed that the positive relationship between ethical leadership and OCBs was stronger for those lower in organizational identification than for those higher in identification. Overall, the findings of the study shed new light on the conditions through which ethical leadership enhances OCBs.
