A new approach to surface photovoltage measurements on hydrogenated microcrystalline silicon layers

A new approach to the surface photovoltage method is demonstrated on thick undoped microcrystalline silicon films grown on different substrates. The model, which includes top as well as bottom space-charge regions, gives a good picture of rather complex experiments and allows good fitting of theoretical curves to experimental results. This method gives us not only the diffusion length of minority carriers but also information on the existence and properties of the space-charge regions in the sample and the results are verified by comparison with the standard procedure.     

Principles of part-whole selective perception by dynamic touch extend to the torso

The haptic subsystem of dynamic touch expresses a novel form of part-whole selective perception. When wielding a nonvisible rod grasped at some intermediate point along its length, an individual can attend to and report the length of a part of the rod (e.g., the segment forward of the hand) or the length of the whole rod. Both perceptions relate to the rod's mass moments about the point of grasp but in systematically different ways. Previous demonstrations of this part-whole selectivity have been in respect to rods grasped by hand or attached to a foot. The authors demonstrated the part-whole selectivity for nonvisible rods attached to the shoulder girdle and wielded primarily by movements of the trunk with benchmark performance provided by the same rods grasped and wielded by hand. Their results suggest that part-whole selectivity is a haptic capability general to the body.     

The three-factor model of Internet addiction: The development of the Problematic Internet Use Questionnaire

Despite the fact that more and more clinical case studies and research reports have been published on the increasing problem of Internet addiction, no generally accepted standardized tool is available to measure problematic Internet use or Internet addiction. The aim of our study was to create such a questionnaire. On the basis of earlier studies and our previous experience withYoung's (1998a) Internet Addiction Test, initially, we created a 30-item questionnaire, which was assessed together with other questions regarding participants' Internet use. Data were collected online from 1,037 persons (54.1% of them male; mean age, 23.3 years; SD, 9.1). As a result of reliability analysis and factor analysis, we reduced the number of items to 18 and created the Problematic Internet Use Questionnaire (PIUQ) containing three subscales: obsession, neglect, and control disorder. Cronbach's alpha of the PIUQ is .87 (Cronbach's alpha of the subscales is .85, .74, and .76, respectively). The test-retest correlation of the PIUQ is .90. The PIUQ proved to be a reliable measurement for assessing the extent of problems caused by the "misuse" of the Internet; however, further analysis is needed.     

Disgust Sensitivity and Psychopathological Symptoms: Distinctions from Harm Avoidance

The present study examined the relationship between disgust sensitivity and symptoms of somatization, obsessive-compulsive disorder (OCD), interpersonal sensitivity, depression, anxiety, anger/hostility, phobic anxiety, paranoid ideation, and psychoticism in a community sample. Participants (n = 121) completed the Disgust Scale-2, the Symptom Checklist-90, and the harm avoidance subscale of the Temperament and Character Inventory. Disgust sensitivity was found to be correlated with a broad range of psychopathological symptoms. However, results also indicated that these correlations were partially mediated by harm avoidance. That is, when controlling for levels of harm avoidance, the association between disgust sensitivity and psychopathological symptoms was either substantially reduced or became nonsignificant. These findings suggest that the tendency towards behavioral inhibition to avoid punishment and non-reward may partially account for the association between disgust sensitivity and a broad range of psychopathological symptoms.

Confirmation of the three-factor model of the Assessing Emotions Scale (AES): Verification of the theoretical starting point

Several measures have been developed for the quantification of emotional intelligence. One widely applied method is the Assessing Emotions Scale, whose factor structure has attracted much scientific attention. The objective of the present study was to identify which of the previously suggested models are the most appropriate. By applying confirmatory factor analysis, we have tested the original one-, three-, four-, and six-factor solutions. Results confirmed the three-factor structure to be the most suitable solution. We suggest that the factors in this structure are better described by the labels “appraisal of emotions,” “optimism and regulation of emotions,” and “intrapersonal and interpersonal utilization of emotions.” Supplemental materials for this article may be downloaded from http://brm.psychonomic-journals.org/content/supplemental.     

Exact results related to the periodic Anderson model in D » 1 dimensions

We present exact results related to the T = 0 phase diagram of the periodic Anderson model in the strong coupling U =infinity limit for D = 2,3 dimensions. In a restricted parameter region, a ground state with simple algebraic structure was deduced in both dimensions, and its region of existence was characterized by sufficient conditions. The quasiparticle creation operator that builds up the ground state wave function does not satisfy the standard fermionic anticommutation relations.     

Narrative constructions and the life history issue in brain-emotions relations

Emotional reactions are rather flexible, due to the schema-like organization of complex socio-emotional situations. Some data on emotion development, and on certain pathological conditions such as alexithymia, give further support for the psychological constructivist view put forward by Lindquist et al. Narrative organization is a key component of this schematic organization. The self-related nature of narrative organization provides scaffolding to the contextual dependency of emotions.

Obsessive and harmonious passion in physically active Spanish and Hungarian men and women: A brief report on cultural and gender differences

Increased research on passion in exercise calls for direct examination of possible moderating variables, such as culture and gender, that could influence the interpretation of the research results. This study using a nation by gender between‐participants design, examined differences in obsessive‐ and harmonious passion in Spanish and Hungarian physically active individuals. Participants (n = 1002) completed the Passion Scale, reported their gender, age and weekly hours of physical activity. Multivariate analysis of covariance revealed that the experiencing of physical activity‐related obsessive‐ and harmonious passion differed between the 2 countries and Hungarian women scored significantly higher on harmonious and obsessive passion than Spanish women. However, Hungarian men only scored significantly higher on obsessive passion, but not harmonious passion compared to Spanish men. These results suggest that gender and cultural differences are likely to affect the interpretation and generalisation of research on passion and exercise.
