Psychobiology of altered states of consciousness

The article reviews the current knowledge regarding altered states of consciousness (ASC) (a) occurring spontaneously, (b) evoked by physical and physiological stimulation, (c) induced by psychological means, and (d) caused by diseases. The emphasis is laid on psychological and neurobiological approaches. The phenomenological analysis of the multiple ASC resulted in 4 dimensions by which they can be characterized: activation, awareness span, self-awareness, and sensory dynamics. The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes. Besides these severe alterations, environmental stimuli, mental practices, and techniques of self-control can also temporarily alter brain functioning and conscious experience.     

Exploring Nonlinear Models in Personality Assessment: Development and Preliminary Validation of a Negative Emotionality Scale

ABSTRACT In this article we discuss the applicability of several new measurement models to the construction of personality scales, and we contrast these models with more traditional approaches in common usage, such as the principal factor analysis model. Our goal is to illustrate how nonlinear item-response models can be profitably used in personality research. We describe the development of a 30-item Negative Emotionality scale that was constructed using nonlinear factor analysis and item-response theory. We also show how traditional (linear) factor analysis can produce misleading results when it is applied to personality items with dichotomous response formats (e.g., true/false, agree/disagree). No formal training in modern measurement theory is assumed of the reader as we describe the nonlinear models that are used in this study in nontechnical language with a minimum of mathematics.     

Information technology from a knowledge system perspective: Concepts and issues

Studying knowledge utilization and related processes calls for a conceptual framework. We look at the actors that engage in these processes in a specific field of human activity, and the interfaces and linkages between them, as a Knowledge and Information System (KIS). Although this KIS perspective originates from agriculture it also can be applied to other knowledge domains. Evidence gathered shows that for a KIS to be effective the actors (e.g., researchers, extensionalists, and clients) must act synergically. This inspired us to look for basic KIS principles that indicate opportunities for intervention. This article provides a brief state-of-the-art overview, presents some insights gained to date; and states the main issues for the use of information technology in knowledge management.     

The Extended Body: The Social Body of Jesus according to Luke1

Abstract : Informed by body phenomenology and contemporary concepts of the social body, this article aims to interpret the particular movements and transformations of Jesus’ body as presented in the Gospel of Luke. From the outset Jesus’ body is inscribed in a Jewish genealogy. Likewise, the Gospel depicts the character of Jesus via the various landscapes he passes through as well as through the social interactions of which he is a part. While Jesus’ body is initially described as being energized by the mobile presence of the Spirit, it increasingly closes in and, at the end, simply disappears. Luke describes Jesus’ ascension and resurrection as radical transformations of Jesus’ body, by which Jesus’ body‐and‐mind (Leib) extends into a social body, at home in God as well as among his followers. This social body also crosses the genetic and cultural boundaries between Jews and Gentiles. Only through this extensiveness can Jesus’ body become accessible worldwide.     

Using brain-computer interfaces to overcome the extinction of goal-directed thinking in minimally conscious state patients

Minimally conscious state (MCS) is a condition of severely altered consciousness, in which patients appear to be wakeful and exhibit fluctuating but reproducible signs of awareness. MCS patients do not respond and are therefore dependent on others. In agreement with the embodied cognition assumption that motor actions influence our cognition, the absence of movement and the decrease in consequences for any type of covert or overt response may cause an extinction of goal-directed thinking. Brain-computer interfaces, which allow a direct output without muscular involvement, may be used to promote goal-directed thinking by allowing the performance of spatial and motor imagery tasks and could facilitate the interaction of MCS patients with their environment, possibly regaining some degree of communication and autonomy.     

When does procedural fairness promote organizational citizenship behavior? Integrating empowering leadership types in relational justice models

We examined how procedural fairness interacts with empowering leadership to promote employee OCB. We focused on two core empowering leadership types—encouraging self-development and encouraging independent action. An experiment revealed that leaders encouraging self-development made employees desire status information more (i.e., information regarding one’s value to the organization). Conversely, leaders encouraging independent action decreased employees’ desire for this type of information. Subsequently, a multisource field study (with a US and German sample) showed that encouraging self-development strengthened the relationship between procedural fairness and employee OCB, and this relationship was mediated by employees’ self-perceived status. Conversely, encouraging independent action weakened the procedural fairness-OCB relationship, as mediated by self-perceived status. This research integrates empowering leadership styles into relational fairness theories, highlighting that multiple leader behaviors should be examined in concert and that empowering leadership can have unintended consequences.
