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.     

Are size illusions in simple line drawings affected by shading?

In a number of simple line drawings, such as the Müller-Lyer or Judd figures, we can experience strong distortions of perceived space-geometric illusions. One way of explaining these effects is based on the perspective information that can be read from the line drawings. For instance, the 'inappropriate constancy scaling' theory advocates that the inferred three-dimensional structure of the pictured object is used by the perceptual system to adjust the size of line-drawing components. Such a theory would predict that additional depth cues, for instance shading added to line drawings, should affect these illusions because they influence the three-dimensional appearance. We present here systematic measurements of the magnitude of length misjudgments in horizontal Müller-Lyer and Judd figures for three configurations: (i) pure line drawings, and with shading attached to (ii) the top, and (iii) the bottom of the figures. The latter two configurations are unambiguously interpreted as 'folded' structures with a horizontal edge behind the image plane or protruding from it, respectively. While we could not find any effect of shading in our experimental data, we did observe a length misjudgment in Judd figures that corresponds precisely to the asymmetry that can be observed in the Müller-Lyer illusion for inward and outward fins. This pattern of results is not consistent with notions of inappropriate constancy scaling but is fully coherent with the view that neural filtering mechanisms, which are affecting the perceived position of line intersections, are responsible for this type of geometrical illusions.     

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.     

Assessing the quality of life in patients with multiple sclerosis in Kuwait: a cross sectional study

The main objective of this paper was to assess the level and the determinants of quality of life (QOL) amongst patients with multiple sclerosis (MS). A cross-sectional study was conducted among a convenience sample of 200 adult MS patients. Inclusion criteria were: MS diagnosis for at least one year, and aged 21+ years. However, exclusion criteria were: having other neurological diseases, serious cardiovascular, orthopedic or other disability precluding participation. Self-administered questionnaire employed MSQOL-54 with two outcomes: Physical Health Composite (PHC) and mental health composite (MHC). Satisfaction with Daily Occupation scale was adopted through face to face interviews. The median of PHC and MHC scores were 48.9/100, and 53.4/100 respectively. Multivariate analysis revealed that unemployment was a determinant of poor PHC, while low monthly income was a predictor of poor MHC. Additionally, low endurance and sensory problems were associated with poor PHC, and MHC, while motor problems were allied with only poor PHC. Patient’s satisfaction level with performing activities of daily living was positively associated with PHC and MHC. Assessment of QOL is suggested to be comprised in medical settings.     

Supporting the wellbeing of inner-city middle-school students through mindful and creative reflective activities

Inner-city middle-school students encounter many intersections of the social determinants of health, while expected to learn and to excel academically. However, they lack skills to deal with stress, anger, frustration and sadness, often associated with their social context. To support student wellbeing, we developed a 7-week, 1-hour-session program, which took place during regular class time. Through use of creative reflective activities, namely, Schwind’s Narrative Reflective Process and mindfulness, students learned skills that help support their social and academic wellbeing. Student feedback reveals that creative reflective activities and mindfulness helped foster their inter-intra personal skills in class, enhancing their learning experiences.
