Optimization of Social Structure in Business Networks by Grid-Technique and Polyhedral Analysis

This article deals with the definition and analysis of the social, communicative, and cognitive abilities of managers acting in network contexts. We can tackle the complex relationship of role demands and role adoption by applying grid-technique and polyhedral analysis. We can gather data on context-specific personal constructs with the help of the grid technique. Using these data, polyhedral analysis shows how defined persons are integrated into the relation structures within a network. Beyond this, we show if and how relevant criteria such as holes, connectivity, and eccentricity can be employed for analyzing problems stemming from personnel management. Based upon the applied methods, it is possible to provide information about the relevant structures within networks used in personnel selection and competency development. Decision makers have the task to select among the measures of personnel management. Within the relevant context, these measures should be suited to ensure the stability and efficiency of the network.     

When technology tells you how you drive––truck drivers’ attitudes towards feedback by technology

Behavior based safety approaches have proven effective in reducing accidents in industrial settings, but cannot easily be extended to commercial driving. For considerable periods of working time, truck drivers are alone, and do not interact with peers. It might be possible to use data gathered by new in-vehicle technology to provide real-time and post-shift feedback to drivers about their driving behavior. This paper reports the results of focus group interviews conducted with subject matter experts from the trucking industry (truck drivers, supervisors, managers, and other involved persons, such as insurance industry safety professionals). The focus groups discussed safety critical behaviors in commercial driving, the best way to provide feedback to truck drivers, and benefits of feedback by technology as well as concerns drivers and operators may have regarding monitoring and feedback systems. The focus group discussions showed that, in general, drivers would like to receive more feedback and that feedback by technology is acceptable, if designed and implemented properly. In addition, the participants had many suggestions on how to properly design and implement such systems.     

Complex prospective memory in children with ADHD.

The ability to remember intentions (prospective memory) is fundamental to the organization of goal-directed actions in everyday life. Successful prospective remembering involves forming, retaining, initiating, and executing an intention. Although previous research has demonstrated prospective memory impairments in children with attention deficit/hyperactivity disorder (ADHD), this has largely focused on the intention initiation and execution stages. In this study, we investigate the performance of 20 children with ADHD and 20 matched controls at each of the four stages of prospective memory, using a computer multitask paradigm. Results suggest that children with ADHD may demonstrate difficulties forming delayed intentions, as indicated by impulsive planning, and that this may have further implications for the retention and implementation of these delayed intentions. While children with ADHD showed comparable multitask switching, this appeared to be at the expense of intention execution as they made more performance errors than controls. Implications for day-to-day functioning are discussed.     

New Perspectives on an Old Debate: Friedrich Schleiermacher's Essay on Election

Abstract: This article analyses Schleiermacher's essay on election, which has not received the attention it deserves. I argue that it presents a significant advance in the debate about unconditional grace and the relation between redemption and predestination. While Schleiermacher defends the Augustinian‐Calvinist view of election, he criticizes the ideas of double predestination and eternal damnation (for the unbelievers). Thus, he wants to provide a new basis for Lutherans and Calvinists to settle or, at least, reconsider their longstanding controversy over the matter. After the publication of the essay in 1819, Schleiermacher's doctrine of election remained unchanged, except for minor modifications.     

Are country level prevalences of rule violations associated with knowledge overclaiming among students?

Cultural norms of behaviour influence desirable and problematic behaviours of individuals. In particular, cultural norms should influence individuals' dishonesty. In a recent Nature study, prevalence of rule violations was introduced as a new country‐level measure of behavioural norms. However, information on individuals' actual honesty was not available due to characteristics of the experimental design. Overcoming this limitation, we show that country‐level behavioural norms are related to individual‐level knowledge overclaiming behaviour (i.e., claiming to know concepts that do not exist, a measure of individuals' actual behavioural dishonesty) among 290,954 students from 57 countries (from the 2012 PISA study). Our study represents a crucial test of the argument that cultural norms influence individual's behaviour and of the validity of the measurement of countries' prevalences of rule violations. These results imply that shaping the behaviour of today's students may result in new behavioural norms that emphasise honesty and rule adherence more strongly.     

Zur Prävalenz von Depersonalisation und Derealisation in der stationären Psychotherapie

Depersonalization (DP) and derealization (DR) remain poorly recognized in clinical routine. Active exploration through structured interviews is strongly recommended, because patients rarely describe spontaneously their experiences with DP/DR. 143 psychosomatic, first-admission inpatients were interviewed about the 1-month prevalence of DP/DR using the Structured Clinical Interview for DSM-IV dissociative disorders. Additionally, the German questionnaires of the Cambridge Depersonalization Scale, the Dissociative Experiences Scale, the SCL-90-R and the Inventory of Interpersonal Problems were used. In the sample we found a prevalence of 23.1% (N=33) for depersonalization-derealization syndrom (ICD-10 F48.1) and 7% (N=10) for secondary pathological DP/DR. A total percentage of 62.9% reported DP/DR to some degree or other. There was a noticeably high co-occurrence of anxiety disorders in patients with pathological DP/DR. Patients with pathological DP/DR were generally more impaired, suffered many more interpersonal problems and were particularly characterized by introversion. Considering the high prevalence of this phenomenon, more attention should be paid to DP/DR in routine diagnostic procedures, treatment and research.     

Importance effects on performance in event-based prospective memory tasks

In the present study we manipulated the importance of performing two event-based prospective memory tasks. In Experiment 1, the event-based task was assumed to rely on relatively automatic processes, whereas in Experiment 2 the event-based task was assumed to rely on a more demanding monitoring process. In contrast to the first experiment, the second experiment showed that importance had a positive effect on prospective memory performance. In addition, the occurrence of an importance effect on prospective memory performance seemed to be mainly due to the features of the prospective memory task itself, and not to the characteristics of the ongoing tasks that only influenced the size of the importance effect. The results suggest that importance instructions may improve prospective memory if the prospective task requires the strategic allocation of attentional monitoring resources.     

The redundant target effect is affected by modality switch costs

When participants have to respond to stimuli of two modalities, faster reaction times are observed for simultaneous, bimodal events than for unimodal events (the redundant target effect [RTE]). This finding has been interpreted as reflecting processing gains for bimodal relative to unimodal stimuli, possibly due to multisensory interactions. In random stimulus sequences, reaction times are slower when the stimulus is preceded by a stimulus of a different modality (modality switch effect [MSE]). Simple reaction time redundant target experiments with auditory-visual, visual-tactile, and auditory-tactile stimulus combinations were run to determine whether the RTE may be partly explained by MSEs because bimodal stimuli do not require a modality switch. In all three modality pairings, significant MSEs and RTEs were observed. However, the RTE was still significant after reaction times were corrected for the MSE, supporting the hypothesis that coactivation occurs independently of modality switch costs.     

Being seaward-handed: a computational model of the acquisition of language-specific spatial references

Empirical findings of cross-linguistic studies reveal three different frames of spatial reference: intrinsic, relative, and absolute. Of special interest are relative and absolute systems because they have antagonistic logical implications concerning the dependence on standpoint and orientation of the speaker/hearer. On the background of these findings it becomes crucial to show how an agent can form such language-specific spatial representations. In this paper, the system Locator is introduced as a model of concept formation in the spatial domain. It is assumed that an agent creates necessary discriminative features in processes of self-organization and selection and cannot just discover or find them in its environment. A number of simulations show that agents successfully create concepts of either a relative system (German) or an absolute system (Marquesan), relying solely on multimodal input (visual and linguistic).

The lay assessment of subclinical depression in daily life

This study examined how laypersons assess subclinical depression in others on the basis of information about their daily lives. For 2 days, 96 participants were tracked with the Electronically Activated Recorder, a naturalistic observation method that samples ambient sounds from participants' momentary environments. Judges rated participants' levels of depression after listening to the sampled ambient sounds. Participants' depressive symptoms were assessed with the Beck Depression Inventory. Overall, judges showed little accuracy at determining participants' levels of depressive symptoms from the ambient sounds. Exploratory analyses, however, revealed that judges were more accurate among moderately and severely depressed participants, presumably because the cues judges used to assess depression (e.g., spending time alone, not socializing, not laughing) discriminated successfully only at high levels of subclinical depression.
