Hurry up! The role of supervisors’ time urgency and self‐perceived status for autocratic leadership and subordinates’ well‐being

This study examines the connections among supervisors’ time urgency, their leadership behavior, and subordinate outcomes. Integrating cognitive perspectives on time urgency with contemporary thinking on the psychological experience of status, we reason that supervisors’ time‐urgent personality relates positively with their autocratic leadership behavior, and we cast supervisors’ self‐perceived status as a moderator of this linkage. Moreover, we enrich this leader‐centric perspective with a complementary, more follower‐centric view, recognizing that the consequences of supervisors’ time urgency likely extend beyond their own behavior to indirectly affect their subordinates’ well‐being at work. We tested our hypotheses using a field sample of 60 supervisors and 277 of their subordinates. Results indicate that (a) supervisors with higher time urgency are more likely to exhibit autocratic leadership behavior when they also perceive themselves as having relatively high status among subordinates, but not when perceiving lower status, and (b) supervisors’ time urgency exhibits a conditional indirect effect (via autocratic leadership) on subordinates’ work stress and time pressure experiences. Hence, this study illustrates an important boundary condition for the consequences of supervisors’ time urgency, and it demonstrates that this personality characteristic not only shapes supervisors’ leadership behavior but also affects the subordinates they are charged with leading.     

The assessment of surgery-related coping: The coping with surgical stress scale (COSS)

Abstract

Surgery can be regarded as a major stressor for any patient. High preoperative emotional arousal may negatively influence adjustment during surgery as well as the postoperative recovery rate. Consequently, the strategies individuals employ for coping with this stress are of prime importance for the quality of their adaptation. This paper reports the construction and empirical assessment of a new instrument for measuring strategies employed to cope with surgical stress. Factor analysis of this instrument, the Coping with Surgical Stress Scale (COSS), yielded five factors: Rumination, Optimism and Trust, Turning to Social and Religious Resources, Threat Avoidance, and Information Seeking. Internal consistencies of the corresponding subscales were satisfactory. Results concerning external relationships of the COSS with dispositional coping, state and trait anxiety, and indicators of perioperative adjustment showed that the COSS is a useful instrument for measuring surgery-related coping.     

The Impact of Perceived Corporate Citizenship on Organizational Cynicism,OCB, and Employee Deviance

This study examines the effects of corporate citizenship at the individual employee level. Four distinct contributions beyond the existing literature are offered. First, the relationship between perceived corporate citizenship (PCC) and employee organizational citizenship behavior (OCB) is further clarified. Second, the negative job behavior of employee deviance is considered as an outcome. Third, the attitude of organizational cynicism is positioned as a mediator of the relationships between PCC and the job related behaviors of OCB and employee deviance. Fourth, we disaggregate the PCC measure and explore its relationships with organizational cynicism, OCB and employee deviance. Findings illustrate that the four separate dimensions of PCC have differential relationships with the outcome variables.     

Distant Things: A Closer Look

In a discussion of the constitutive role of colour in our visual perceptual experiences, Wilhelm Schapp centrally argues that we cannot visually perceive certain distant things, like a house seen far down in the valley. My main contention is that, in cases relevantly similar to Schapp’s, we do perceptually experience distant things, viz., as drastically “decayed” things, which are part of distant scenes. In doing so, we adopt towards them a kind of conservative “attitude.” The ideas of decay and scenicness will be unpacked in terms of the Husserlian ideas of fulfilment, and fulfilment conditions, capturing the idea that we perceptually experience objects in terms of anticipated possibilities for further experiences of these objects. These ideas will also be considered in relation to Herbert Leyendecker’s notion of an attitude, e.g. of observing, searching for, or working with objects.     

Kinetic Attraction During Bimanual Coordination

Two experiments examined the effects of independent variations in kinetic and kinematic requirements on interlimb coupling during a bimanual task. The goal of the investigation was to provide preliminary evidence regarding one general class of physical variables that constrains discrete bimanual movements. Subjects attempted to execute a smooth unidirectional movement with the left arm, along with a three-segment reversal movement with the right arm. The first experiment manipulated the torque required to produce the reversal action, while movement duration and average angular velocity were held constant for both limbs. Several indications of increased interlimb coupling, due to the kinetic variation, were evident. The converse manipulation was used in the second experiment, with movement time and kinematics (velocity, acceleration) changed independently of joint torque requirements for the reversal limb. No clear effect of kinematics on coupling strength was noted. The results suggest that one variable influencing interlimb attraction toward common spatiotemporal trajectories may be kinetic in nature.     

Effects of Local Muscular Fatigue Due to Isotonic and Isometric Exercise Upon Fractionated Reaction Time Components

Fractionated RT for a right knee-extension task was assessed on eight male and eight female Ss over eight treatment days. Following four consecutive days of 75 RT trials /day to insure stabilized strength and RT components, Ss were administered two days of bench stepping and two days of isometric exercise designed to induce muscular fatigue of the knee extensors. Significant strength decrements of up to 24% were induced by both the isotonic (bench stepping) and isometric exercise treatment conditions but no changes were observed in fractionated RT components. The results would seem to indicate that performance differences in fine-versus gross-motor skill tasks due to fatigue need to be more carefully examined.     

Response

The theme of love has long been neglected in studies on African myths. The often-heard explanation is that African myths and folktales do not tell stories about love because they primarily express social interests and obligations while love ‐ intended as both emotional imperative and biological drive ‐ is an individual need and feeling. This latter definition relies on a very specific understanding of ‘love’: the Romantic love of 19th century European novels. This paper argues that when love means attraction, affection, passion, and necessity, it turns up as liaisons dangereuses in many African narratives. Love becomes a driving force that generates gender constructions by reinforcing the unity of the couple or by fuelling the struggle between partners. In the case of Kabyle narratives (Algeria),1 conceptualisations of love as well as the relationships between myths and folktales are explored by analyzing formula tales2 and the only known collection of Kabyle Berber myths: those collected by Leo Frobenius, ethnologist and historian of religion, at the beginning of the 20th century and published in the first volume of his Volksmarchen der Kabylen in 1921. The discussion of the relationship between Kabyle myths and folktales touches upon a well-known interpretative problem in the study of religion: the articulation of myth and ritual with history as communities respond to sweeping social, political, and religious changes, such as the coming of Islam, colonization, decolonization, and globalization.     

Unidirectional Mazes for use with Animals

One hundred twenty goldfish were differentially trained with large and small reward in a shuttle swimway. The end compartments and the swimming directions for a given S were consistently identifiable over all trials with either a large or small magnitude of reward. Negative contrast effects were obtained in the start measure for Ss with short intervals between trials. The results suggest similar mechanisms for rat and goldfish performance in differential conditioning studies.
