The Configuration of Performance Appraisal: Investigating the Impact of Leadership and Personality Using a Within- and Between-Supervisory Group Analysis

The key to improvfrig performance appraisals in organizations may be the leadership exchange processes that occur between managers and subordinates. We suggest two ways in which this might unfold: (a) the direct relationships among leadership attention, tenure with supervisor, and actual performance appraisal rating and (b) the cqnfiguration of these three variables around the organization\u27s structure in which differences between supervisory groups are highlighted. Our findings suggest that all three variables are significantly related. For leadership attention and performance appraisal, an individual-level model best applies. A group model is implied for leaders~ip attention and tenure with supervisor, whereby entire supervisory groups that have longer tenure with their supervisor also receive, on average, higher amounts of leadership attention

Instantaneous Normal Mode analysis of liquid HF

We present an Instantaneous Normal Modes analysis of liquid HF aimed to clarify the origin of peculiar dynamical properties which are supposed to stem from the arrangement of molecules in linear hydrogen-bonded network. The present study shows that this approach is an unique tool for the understanding of the spectral features revealed in the analysis of both single molecule and collective quantities. For the system under investigation we demonstrate the relevance of hydrogen-bonding ``stretching'' and fast librational motion in the interpretation of these features.Comment: REVTeX, 7 pages, 5 eps figures included.

Instantaneous Normal Mode Analysis of Supercooled Water

We use the instantaneous normal mode approach to provide a description of the local curvature of the potential energy surface of a model for water. We focus on the region of the phase diagram in which the dynamics may be described by the mode-coupling theory. We find, surprisingly, that the diffusion constant depends mainly on the fraction of directions in configuration space connecting different local minima, supporting the conjecture that the dynamics are controlled by the geometric properties of configuration space. Furthermore, we find an unexpected relation between the number of basins accessed in equilibrium and the connectivity between them.Comment: 5 pages, 4 figure

Compiling a Comprehensive EVA Training Dataset for NASA Astronauts

Training for a spacewalk or extravehicular activity (EVA) is considered hazardous duty for NASA astronauts. This activity places astronauts at risk for decompression sickness as well as various musculoskeletal disorders from working in the spacesuit. As a result, the operational and research communities over the years have requested access to EVA training data to supplement their studies

Pop stars and idolatry: an investigation of the worship of popular music icons, and the music and cult of Prince.

Prince is an artist who integrates elements from the sacred into his work. He uses popular iconography to present himself as an icon of consumer culture, as a deified ‘rock god’ worshipped by his fans, and as a preacher leading his audience like a congregation. His personality cult mixes spirituality and sexuality, and deals with issues of ecstasy and liberation, a transgressional approach that draws both controversy and public interest. This paper investigates Prince’s work and the role of the pop star as an icon within contemporary culture, an icon that contains a physicality and sexuality not present in contemporary western religious traditions. It discusses to what extent popular musical culture operates as a form of religious practice within contemporary western culture, and the implications that this has. The paper investigates the construction of Prince’s public character, his manipulation of the star system, and how he uses popular iconography to blur the distinctions between spirituality and sexuality, the idealised performer and the real world, the sacred and the profane, and the human and the divine. It explores how he possesses and is possessed by the audience, who enter into the hollow vessel he offers up to his fans
