Artistic beauty and religious sublimity in literature: a Levinasian reproach of estheticism in light of Kant’s third Critique

International Journal for Philosophy of Religion - Emmanuel Levinas’s doubts about the ethical value of artistic beauty have been widely acknowledged by the vast majority of Levinas’s...     

Abnormal diurnal pattern of cortisol secretion in patients after aneurysmal subarachnoid hemorrhage

Substantial evidence suggests that impairment of the hypothalamus?pituitary system can occur following an aneurysmal subarachnoid hemorrhage (aSAH). Given that the diurnal cortisol rhythm is primarily controlled by the hypothalamus?pituitary system, this study examined whether changes in diurnal cortisol rhythm occurred after aSAH. Cortisol concentrations were measured in the saliva samples collected from patients after aSAH and other types of cerebral hemorrhage (non-aSAH) in the post-awakening period and at night (21:00?h), and the cortisol awakening response (CAR) and diurnal cortisol decline were determined. The area under the cortisol curve from immediately after to 45?min after awakening (CARauc) in the aSAH patient group was comparable to that in the non-aSAH or healthy control groups. However, an obvious cortisol peak was not found after the awakening period, and the morning/nighttime cortisol ratio in the aSAH patient group was significantly lower than that in other examined groups due to higher nighttime cortisol concentrations. In aSAH patients, the CARauc and nighttime cortisol concentrations were negatively correlated with the Fisher CT grade. These results indicate that the diurnal cortisol rhythm is not regulated normally after aSAH, and cortisol secretory activity decreases as the volume of subarachnoid bleeding increases. Our findings will be helpful to understand altered hypothalamus?pituitary?adrenal axis function after aSAH.     

Wishing for Change in Japan and Canada

Japanese and Canadian university students were compared on the changes they wanted in their lives. Contrary to their characterization as self-effacingly relational and group-minded, Japanese were no more likely than Canadians to wish for social or collective goods. Rather, Japanese were more likely than Canadians to wish for money or material goods, and less likely than Canadians to wish for better family relations, increased self-understanding, and improved academic performance. Whether these findings reflect dissimilar cultural priorities, unequal opportunities and constraints, or both, is discussed.     

Computation of mean size is based on perceived size

The present study investigated whether computation of mean object size was based on perceived or physical size. The Ebbinghaus illusion was used to make the perceived size of a circle different from its physical size. Four Ebbinghaus configurations were presented either simultaneously (Experiment 1) or sequentially (Experiment 2) to each visual field, and participants were instructed to attend only to the central circles of each configuration. Participants’ judgments of mean central circle size were influenced by the Ebbinghaus illusion. In addition, the Ebbinghaus illusion influenced the coding of individual size rather than the averaging. These results suggest that perceived rather than physical size was used in computing the mean size.     

Morphological changes in dendritic spines of Purkinje cells associated with motor learning

Experience-dependent changes of spine structure and number may contribute to long-term memory storage. Although several studies demonstrated structural spine plasticity following associative learning, there is limited evidence associating motor learning with alteration of spine morphology. Here, we investigated this issue in the cerebellar Purkinje cells using high voltage electron microscopy (HVEM). Adult rats were trained in an obstacle course, demanding significant motor coordination to complete. Control animals either traversed an obstacle-free runway or remained sedentary. Quantitative analysis of spine morphology showed that the density and length of dendritic spines along the distal dendrites of Purkinje cells were significantly increased in the rats that learned complex motor skills compared to active or inactive controls. Classification of spines into shape categories indicated that the increased spine density and length after motor learning was mainly attributable to an increase in thin spines. These findings suggest that motor learning induces structural spine plasticity in the cerebellar Purkinje neurons, which may play a crucial role in acquiring complex motor skills.     

Interplay between Attachment to Peers and Parents in Korean Adolescents’ Behavior Problems

The present study investigated the relative contribution of style of peer attachment (secure, anxious, avoidant) and quality of attachment to parents on behavior problems in Korean adolescents. In addition, we examined the role of paternal and maternal attachment separately as a potential moderator in the relationship between style of peer attachment and internalizing and externalizing behavior problems. Middle school students (245 males, 209 females) completed the Korean version of the Adolescent Friendship Attachment Scale, Inventory of Parental and Peer Attachment-Revised, and Youth Self-Report. Attachment to peers and parents as predictors of behavior problems were tested via hierarchical multiple regression analyses. Results revealed that anxious peer attachment remained the strongest predictor of behavior problems among adolescents (internalizing behavior problems β?=?.18, p?<?.01; externalizing behavior problems β?=?.21, p? <?.001), indicating the relative importance of peer relationship compared to attachment to parents. Paternal attachment significantly moderated the relationship between avoidant peer attachment and externalizing behavior problems (β?=?.15, p?<?.05), even when the main effect of avoidant peer attachment on externalizing behavior problems was not significant. Results highlight the role of both attachments to peers and parents on adolescents’ psychological adjustment.     

Self-concept clarity’s role in meaning in life among American college students: A latent growth approach

Meaning in life (MIL) is a fundamental building block of well-being, and MIL theory heavily emphasizes the importance of using self-knowledge to identify what makes life meaningful and to select suitable purposes to pursue in life. However, few studies have investigated this important theoretical point. The purpose of the present study was to investigate individual growth trajectories of self-knowledge, measured with a construct of self-concept clarity (SCC), and MIL. This study also examined whether the change of SCC predicts the change pattern of MIL using cross-domain latent growth analyses, controlling for the level of perceived stress. A longitudinal data-set with seventh measurement points was gathered from a total of 285 college students at a large Midwest university in the US during the period of 8 weeks. On average, a student’s levels of MIL and SCC tend to show a small amount of linear increase during the first semester of college, with individual differences in patterns of change. From a change perspective, SCC significantly predicted the sense of MIL, supporting the significance of having a clear self-view in perceiving life as more meaningful.     

Laboratory Safety and Nanotechnology Workers: an Analysis of Current Guidelines in the USA

Although some regulatory frameworks for the occupational health and safety of nanotechnology workers have been developed, worker safety and health issues in these laboratory environments have received less attention than many other areas of nanotechnology regulation. In addition, workers in nanotechnology labs are likely to face unknown risks and hazards because few of the guidelines and rules for worker safety are mandatory. In this article, we provide an overview of the current health and safety guidelines for nanotechnology laboratory workers by exploring guidelines from different organizations, including the Department of Energy Nanoscale Science Research Centers (DOE-NSRC), Massachusetts Institute of Technology (MIT), the National Institutes of Health (NIH), the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Administration (OSHA), Texas A&M University (TAMU), and University of Massachusetts-Lowell (UML). After discussing these current guidelines, we apply an ethical framework to each set of guidelines to explore any gaps that might exist in them. By conducting this gap analysis, we are able to highlight some of the weaknesses that might be important for future policy development in this area. We conclude by outlining how future guidelines might address some of these gaps, specifically the issue of workers’ participation in the process of establishing safety measures and the development and enforcement of more unified (and mandatory) guidelines.
