Openness to Experience,Ethical Leadership,and Innovative Work Behavior

Drawing on trait activation theory, we examine ethical leadership as a boundary condition on the relationship between openness to experience and innovative work behavior. We collected data from 291 subordinates and 51 supervisors to test our theoretical model. Our results suggest that openness to experience was positively related to innovative work behavior. Furthermore, this relationship was only significant when ethical leadership was perceived high as compared to low. Our research contributes to the literatures on innovative work behavior and ethical leadership.     

How to Accommodate to the Invisible? The ��halo�� of ��nano��

Nanotechnologies produce many different types of images but are characterized by the ones that allow us to ??see the atoms?? despite the fact that objects at the nanoscale are smaller than the wavelength of light and hence are ??invisible??. Images from scanning probe microscopy (SPM), like ??The Beginning??, have played an emblematic role in the constitution of the field and are also more likely to be used in communication outside the scientific field. These images are made, selected, modified and evaluated with respect to the information that they communicate. The ??life cycle?? of these images implies the transduction of this information. Outside of the scientific field, however, they are no longer defined by this information, nor according to technical and scientific criteria, but by their aesthetic power, and they become associated with other images from other fields (art, advertisement, entertainment). This process creates a psycho-social ??halo?? about ??nano?? in the public perception, and raises ethical issues about nanotechnological communication via images. We will analyze the halo of the nano in this respect and propose a strategy for a reflexive ??accommodation?? to the images at the nanoscale.     

Individual differences in the anterior insula are associated with the likelihood of financially helping versus harming others

The neural basis of individual differences in positive and negative social decisions and behaviors in healthy populations is yet undetermined. Recent work has focused on the potential role of the anterior insula in guiding social and nonsocial decision making, but the specific nature of its activation during such decision making remains unclear. To identify the neural regions mediating individual differences in helpful and harmful decisions and to assess the nature of insula activation during such decisions, in the present study we used a novel fMRI task featuring intentional and unintentional decisions to financially harm or help persons in need. Based on a whole-brain, unbiased approach, our findings indicate that individual differences in dorsal anterior insula, anterior cingulate cortex (ACC), and right temporo-parietal junction activation are associated with behavioral tendencies to financially harm or help another. Furthermore, activity in the dorsal anterior insula and ACC was greatest during unintended outcomes, whether these were gains or losses for a charity or for oneself, supporting models of the role of these regions in salience prediction error signaling. Together, the results suggest that individual differences in risk anticipation, as reflected in the dorsal anterior insula and dorsal ACC, guide social decisions to refrain from harming others.     

Understanding the unique impact of dimensions of ethical leadership on employee attitudes

This study extends earlier findings on ethical leadership by testing the relationship of the seven dimensions of ethical leadership with job satisfaction, organization commitment, job embeddedness, and cynicism. It uses time-lagged data from 585 employees in Pakistan. Using confirmatory factor analysis and structural equation modeling, the study supports the concept of multidimensional ethical leadership in the Eastern setting and indicates that the dimensions of people orientation, fairness, power sharing, ethical guidance, and role clarification are associated with the majority of outcomes, as suggested by social exchange theory. However, the concern for sustainability and integrity dimensions had a limited effect.     

Inclusive Leadership and Innovative Work Behavior: Examination of LMX Perspective in Small Capitalized Textile Firms

The purpose of this paper is to explore the relationship between inclusive leadership, Leader-Member Exchange (LMX) and innovative work behavior (IWB) in employees of small capitalized textile firms of Pakistan. We hypothesized that LMX mediates the relationship between inclusive leadership and IWB. We collected data from 150 supervisors–subordinate dyads to test our hypotheses. We selected small capitalized firms because they are more innovative and change-oriented in order to enhance their innovativeness. Moreover, these firms enjoy the benefits of lack of bureaucracy and low resistance to change. Therefore, employees are better able to experience a close relationship with entrepreneurial leaders who tend to be inclusive, in order to facilitate the process of innovation. In line with these facts, our results also suggest that inclusive leadership is positively related with IWB and LMX partially mediates this relationship. The theoretical and practical implications of our findings are also discussed.     

Fading in

Patient H.M. can form new memories and maintain them for a few seconds before they fade away. From a neurobiological perspective, this amnesia is usually attributed to the absence of memory consolidation, that is, memory storage. An alternative view holds that this impairment reflects that the memory is present but cannot be retrieved. This debate has been unresolved for decades. Here, we will consider some of the arguments that make it so difficult to resolve this issue. In addition, some recent work will be discussed that has gone beyond the shortcomings of previous experimental approaches to strongly suggest that amnesia can be due to a retrieval impairment that can be overcome with a reminder--an example of memories fading in. Finally, this review will suggest some strategies for resolving this debate.     

Episodic and semantic remote autobiographical memory in ageing

Many laboratory studies have demonstrated an age effect on episodic memory which is in contrast with the preservation of semantic memory. The aim of this study was the assessment of age effects on autobiographical memory according to the length of the retention interval, taking into account the episodic and semantic components. A total of 52 subjects, aged between 40 and 79, were divided into four age groups. They were tested with a sophisticated autobiographical questionnaire consisting of two tasks, one involving the recall of semantic information and another the recall of episodic events. Results revealed that episodic recall deteriorated more with age and retention interval than semantic recall. These data, gathered using an ecological test, confirm age differences demonstrated by laboratory tests on the episodic-semantic distinction. Furthermore, the profile of results obtained for the recall of specific detailed events, and analysed according to age of encoding, confirms the distribution of episodic memories across the lifespan, as modelled by Rubin, Wetzler, and Nebes (1986) with the cue-word technique.     

Treatment with medications affecting dopaminergic and serotonergic mechanisms: effects on fluency and anxiety in persons who stutter

Medications with dopamine antagonist properties, such as haloperidol, and those with serotonin reuptake inhibitor properties, such as clomipramine, have been shown to improve fluency. To examine the degree to which each of these two pharmacological mechanisms might independently affect fluency, a selective serotonin reuptake inhibitor, paroxetine, and a selective dopamine (D-2) antagonist, pimozide, were evaluated. Both types of medications also affect mood and anxiety, factors that could influence fluency levels. Therefore, we also evaluated the medications’ effects on generalized and speech-related anxiety and the relationships between changes in anxiety and changes in fluency in 11 subjects with a history of developmental stuttering. The randomized, double blind, placebo-controlled crossover study that was designed had to be terminated prior to completion due to severe side effects following withdrawal from paroxetine. Even with a reduced sample size (n = 6), significant improvement in percent fluent speaking time (p = 0.02) was found using a telephone task between baseline and pimozide (n = 6), with average duration of dysfluencies significantly shorter (p = 0.04) but no significant difference in the estimated number of dysfluencies per minute. This significant improvement was associated with non-significant increases in generalized anxiety, but non-significant decreases in speech-related anxiety. No significant differences were found in fluency between baseline and paroxetine (n = 5). These preliminary results suggest that fluency improvement is more likely to be mediated by dopaminergic rather than serotonergic mechanisms. Due to its side effects, however, pimozide may be considered a risk for treatment of stuttering.

Educational objectives: As a result of reading this paper the reader will describe and explain: (1) how medications may affect fluency and the rationale for selecting medications for treatment trials; (2) the interrelationship between fluency and anxiety; and (3) factors important in developing clinical trials using medications.
