The Aesthetic Import of the Act of Knowledge and its European Roots in Merab Mamardašvili

What Mamardašvili meant by “process of knowledge” is not an all-embracing vision of reality accomplished “once-and-for-all”; it is not a step by step procedure of deduction; rather it is an anti-dialectical reconstruction of a constellation of signs put together over and over again by the subject by an act of non-premeditated genius. It is a kind of aesthetic act that makes the sense appear, like a vertical cut in the sequential line of space and time.     

Estimation of Transient Error in Cognitive Ability Scales

In response to Schmidt, Le, and Ilies' (2003) call for further assessment of transient error variance in measures of key individual difference variables, the current study examines transient error estimates for eight speeded cognitive ability scales and a composite scale. One hundred twenty‐three participants were tested on two occasions with a 1‐week interval between administrations. Estimates of transient error ranged from a low of .01 to a high of .18, with an average value of .09. The coefficient of equivalence, based on the split‐half method, resulted in overestimates of reliability by as little as 1.90% to as much as 25.96%, with an average 12.96%.     

Understanding Self-Report Bias in Organizational Behavior Research

Self-report and mono-method bias often threaten the validity of research conducted in business settings and thus hinder the development of theories of organizational behavior. This paper outlines a conceptual framework for understanding factors that influence the motivation of an employee to bias his or her responses to questions posed by organizational researchers. Using a longitudinal, multitrait-multimethod dataset, we illustrate various aspects of the problem and argue that traditional approaches for controlling self-report bias do not adequately prevent the problem. The results suggest the need for developing a theory of method effects and companion analytic techniques to improve the accuracy of psychological research in business settings.     

Evaluation of Siddha Samadhi Yoga for anxiety and depression symptoms: a preliminary study

Siddha Samadhi Yoga is a program in which meditation is associated with pranayama (breathing exercises). 22 volunteers with anxiety complaints (M age = 42.8 yr., SD = 10.3) were assigned to two groups: 14 attended the yoga group, and 8 attended a waiting-list or control group. They were evaluated before the intervention and 1 month after it on the State-Trait Anxiety Inventory, the Beck Depression Inventory, Tension Feelings Self-evaluation Scales, and the Well-being Self-evaluation Scales. A significant reduction in scores on anxiety, depression, and tension was found in yoga group, as well as an increase in well-being in comparison with the control group.     

The Influence of Clinical Variables on the Psychological Adaptation of Adolescents after Solid Organ Transplantation

This study assessed the influence of clinical and socio-demographic variables on the psychological adaptation of transplanted adolescents. Twenty-six transplanted adolescents and 25 healthy adolescents, aged 13–17, and their parents participated in the study. The following domains were measured: social competence, emotional/behavioral problems, self-concept, self-esteem and subjective well-being. The findings revealed that transplanted boys presented significantly less social competence (U = 26,000, p < .05) and more externalizing problems (U = 25,000, p < .05), social problems (U = 25,000, p < .05) and attention problems (U = 17,500, p < .01) than healthy boys. In contrast, transplanted girls displayed significantly more internalizing problems (U = 47,000, p < .05) and lower physical self-concept (U = 49,500, p < .05) than healthy girls. Hierarchical regression analysis showed clinical variables, especially waiting-list time, significantly predicted attention problems (β = .364, p < .05) and negative affect (β = .632, p < .05) in transplanted adolescents. Also, male (β = −0.554, p < .01) and younger (β = −0.444, p < .01) transplanted adolescents were at risk for attention problems. Our data suggest the importance of the waiting-list time for transplanted adolescents. Efforts to reduce the pretransplant phase would help adolescents achieve better psychological adaptation at long-term posttransplant.     

Non‐generalized and generalized conditioned reinforcers: establishment and validation

Conditioned reinforcers, or tokens, are frequently used in clinical settings; however, little applied research has focused on establishing and validating their effectiveness. Following pairing of a novel token with an edible reinforcer in the present study, preference and reinforcer assessments verified that the tokens functioned as conditioned reinforcers. Results indicated that the tokens were established as conditioned reinforcers that matched the reinforcer value of the primary reinforcers with which they had been paired. The effects of motivating operations (MOs) on the effectiveness of these conditioned reinforcers were then evaluated. Conditioned reinforcer effectiveness decreased during satiation conditions. Subsequently it was found that increasing the number of backup reinforcers with which the token was paired resulted in the effectiveness maintaining during satiation conditions.

The Net in the Park

Ubiquitous Computing, Pervasive Computing, Physical Computing, Everyware, Tangible User Interface, and the Internet of Things all share the same viewpoint—a viewpoint that sees computers, phones, and game consoles as no longer being the only devices in our environment deemed worthy to embody computation and be connected. Each of these approaches focuses on slightly different aspects of the features and potentialities of the enabling technologies (i.e., Physical Computing focuses on the growing power of microcontrollers; IOT on the increasing influence of tagging systems; Everyware on the pervasiveness of the web through wired and wireless connections, etc.) We understand and place more emphasis on the similarities then the differences among these approaches, and at the same time, we try to address specific human activity issues by exploiting these new enabling technologies and visions. In the paper, we present a project, Wi-roni, that addresses two issues: in-person communication and the added value of being in a given location when accessing a given content. To this end, we considered in some detail the possibilities of three of these enabling technologies: ultrasound sensors, MEMS, and mash-up of Internet application. These technologies were chosen based on the nature of the human activity, and not vice versa. In Wi-roni, an Urban Architecture project located in the La Gora public park in Monteroni d'Arbia, a small village in the province of Siena (Italy), we developed two interconnect solutions: Wi-wave, a column for accessing web audio content in public spaces, and Wi-swing, a children’s swing that tells stories while swinging. These devices represent both the concrete grounds from which to begin to address the abovementioned human activity issues and the playground in which to explore the new, emerging interaction modalities that the enabling technologies could allow.     

Working Passions: Emotions and Creative Engagement with Value

It is now a commonplace that emotions are not mere sensations but, rather, conceptually contentful states. In trying to expand on this insight, however, most theoretical approaches to emotions neglect central intuitions about what emotions are like. We therefore need a methodological shift in our thinking about emotions away from the standard accounts' attempts to reduce them to other mental states and toward an exploration of the distinctive work emotions do. I show that emotions' distinctive function is to engage us with both objective and personal values. Attention to emotions' work reveals that it is precisely their “unruliness” that allows them to play meaningful roles in our lives.
