Organizational Tenure Diversity as Predictors of Combat Performance in ROK Army

Drawing on the upper-echelons theory and diversity issues, this study examines the relationships between top management team (TMT) organizational tenure, tenure diversity, and combat performance. The study is based on of Korea Combat Training Center (KCTC) that is designed for training and evaluation of the battalion combat power. Findings indicate that battalions with higher levels of TMT tenure have a positive effect on combat performance. Tenure diversity of TMT has a negative effect on combat performance. In addition, results showed that the negative relationships between tenure diversity of TMT and combat performance are attenuated by commander’s shared experience with other TMT members.     

Structural and functional information—an evolutionary approach to pragmatic information

The paper starts with a critics of the potential information which is related to the statistical entropy. In order to include the syntactic and semantic aspects of information, we propose a distinction between structural and functional information, instead. Structural information represents the structural determination of a system state, it measures the content of information, as given by the material structure. Functional information, on the other hand, represents the operational closure of the system, it could be e.g. an algorithm which activates and interprets the existing structural information.

From an evolutionary point of view, pragmatic information is generated by an interplay of structural and functional information. This leads to a new insight into the concept of pragmatic information, which is not an invariant of evolution, but must be steadily re‐generated.

The active role of information in a self‐organization process is demonstrated in a model of artificial agents. It is shown by means of computer simulations that the feedback of already existing information on the generation of new information performs analogies to the creation of a collective memory.     

Patients' experiences of forensic psychotherapy

In forensic psychotherapy there may be competing goals and agendas, influenced respectively by concerns about mental health and well-being, risk reduction and psychodynamically-significant change. There has, to date, been no published study of the goals and concerns of forensic patients undergoing therapy. Semi-structured interviews with ten patients considered by their therapists as having gained from forensic psychotherapy were analysed thematically. Results indicate the importance to patients of trust and acceptance in the therapeutic relationship, and changes in the domains of perception of self and interpersonal functioning as well as changes in problematic behaviours. These findings have implications for the choice of measures in systematic outcome research.     

Intensity profiles of emotional experience over time

A full understanding of emotions and emotion characteristics can only be reached when their dynamic nature is taken into account. As such, a primary objective of the present study is to describe and account for variability in temporal profiles of experienced emotional intensity. Participants were asked to make detailed drawings of intensity profiles of recently experienced episodes of anger, sadness, joy and affection. Functional data analysis revealed three features that together accounted for 84% of the total variability: (i) steepness at onset; (ii) skewness; and (iii) the number of peaks. Emotions differed with regard to the first two features, with the rise at onset being steeper for sadness and joy and affection being the most negatively skewed emotion under study. Individual differences regarding each of the three features were found, however, they did not strongly generalise across emotions.     

The relationship between blushing propensity,social anxiety and facial blood flow during embarrassment

To investigate blushing in relation to blushing propensity scores and core elements of social anxiety, facial blood flow was monitored in 86 normal volunteers during an embarrassing task (singing a children's song). Increases in facial blood flow were greater in women than men, as were scores on the Blushing Propensity and Fear of Negative Evaluation scales. In addition, high scores on the Blushing Propensity and Social Interaction Anxiety scales were associated with large increases in facial blood flow during singing. However, this appeared to be due primarily to social anxiety because the association between blushing propensity scores and changes in facial blood flow disappeared when social interaction anxiety scores were taken into account. These findings suggest that people generally base their beliefs about blushing on cues other than changes in facial blood flow. Social anxiety may augment increases in facial blood flow during embarrassment, independently of expected or perceived blushing.     

Affective biases in English are bi-dimensional

A long-standing observation about the interface between emotion and language is that positive words are used more frequently than negative ones, leading to the Pollyanna hypothesis which alleges a predominantly optimistic outlook in humans. This paper uses the largest available collection of affective ratings as well as insights from linguistics to revisit the Pollyanna hypothesis as it relates to two dimensions of emotion: valence (pleasantness) and arousal (intensity). We identified systematic patterns in the distribution of words over a bi-dimensional affective space, which (1) run counter to and supersede most prior accounts, and (2) differ drastically between word types (unique, distinct words in the lexicon) and word tokens (number of occurrences of available words in the lexicon). We argue for two factors that shape affect in language and society: a pro-social benevolent communication strategy with its emphasis on useful and dangerous phenomena, and the structure of human subjective perception of affect.     

Event-related cerebral hemodynamics reveal target-specific resource allocation for both “go” and “no-go” response-based vigilance tasks

Transcranial Doppler sonography was used to measure cerebral blood flow velocity (CBFV) in the right and left cerebral hemispheres during the performance of a 50-min visual vigilance session. Observers monitored a simulated flight of unmanned aerial vehicles for cases in which one of the vehicles was flying in an inappropriate direction relative to its cohorts. Two types of vigilance tasks were employed: a traditional task in which observers made button press (“go”) responses to critical signals, and a modification of the traditional task called the Sustained Attention to Response Task (SART) in which “go” responses acknowledged nonsignal events and response withholding (“no-go”) signified signal detection. Signal detections and global CBFV scores declined over time. In addition, fine-grained event-related analyses revealed that the detection of signals was accompanied by an elevation of CBFV that was not present with missed signals. As was the case with the global scores, the magnitude of the transient CBFV increments associated with signal detection also declined over time, and these findings were independent of task type. The results support the view of CBFV as an index of the cognitive evaluation of stimulus significance, and a resource model of vigilance in which the need for continuous attention produces a depletion of information-processing assets that are not replenished as the task progresses. Further, temporal declines in the magnitude of event-related CBFV in response to critical signals only is evidence that the decrement function in vigilance is due to attentional processing and not specific task elements such as the required response format.     

Emotion and reason in everyday risk perception

Although research has documented the importance of emotion in risk perception, little is known about it in the context of everyday life. Using the Experience Sampling Method (ESM), 94 part‐time students were prompted at random—via cellular telephones—to report on mood state and three emotions and to assess risk on thirty occasions during their working hours. The emotions—valence, arousal, and dominance—were measured using self‐assessment manikins (SAMs) (Bradley & Lang, 1994). Hierarchical linear models (HLM) revealed that mood state and emotions explained significant variance in risk perception. In addition, valence and arousal accounted for variance over and above “reason” (measured by severity and possibility of risks). Six risks were re‐assessed in a post‐experimental session and found to be lower than their real‐time counterparts. The study demonstrates the feasibility and value of collecting representative samples of data with simple technology. Evidence is also provided to demonstrate the statistical consistency of the HLM estimates. Copyright © 2010 John Wiley & Sons, Ltd.
