Factors related to the satisfaction and performance of temporary employees.

Previous research suggests that whether temporary employees are voluntary or involuntary in their choice to pursue temporary work is related to satisfaction levels. This study investigated whether voluntarily or involuntarily pursuing temporary work is related to satisfaction and performance. Previous work has classified individuals as voluntary or involuntary when operationalizing the decision to pursue temporary work. This study used a more complex measure that addressed individuals' reasons for pursuing temporary work. Analyses were conducted using the complex measure and a traditional classification. The results suggest 4 conclusions: (a) a complex measure may be preferred over a dichotomous classification when operationalizing the decision to pursue temporary work, (b) individuals who are involuntarily pursuing temporary work may be less satisfied, (c) whether an individual voluntarily pursues temporary work appears to be unrelated to satisfaction levels, and (d) whether an individual is voluntarily or involuntarily pursuing temporary work is unrelated to performance.

Impact of national culture on information technology usage behaviour: an exploratory study of decision making in Korea and the USA

The globalization of world markets has led to the introduction of information technology, most often developed in western cultures, to other societies. Cultural values were embedded in the design and use of these technologies. Often, the receiving society did not embrace the technology because of culture. Examples of such behaviour include executive information systems and group decision support systems, which are cited later. This study examines the use of non-specific applications of information technology for organizational decision making. A survey instrument was developed to measure decision makers' perceptions of the impact of information technology on the decision process. Decision makers in Korea and the USA indicated their perceptions of the extent information technology use impacted their decision making activities. The results indicated some behaviours appeared to change to take advantage of the technology, while others, particularly those associated with the cultural preference for communication, did not.     

A somatodendritic distribution of Rab11 in rabbit brain neurons

Comparisons of subcellular targeting in neurons and epithelial cells have led to suggestions that apical epithelial antigens localize to axons and nerve terminals. We have studied the distribution in brain of the small GTP-binding protein, Rab11, which is localized to apical vesicular populations in epithelial cells. Sections of rabbit brain were examined by immunohistochemistry using a monoclonal antibody against rabbit Rab11. Rab11 immunoreactivity was present exclusively in neurons. In all regions examined, including forebrain, cerebellum, thalamus and brainstem, Rab11 immunoreactivity was observed in cell bodies and dendrites. No staining was observed in hippocampal neurons. These results indicate that the distribution of Rab11 does not support previous suggestions that apical epithelial markers should localize to axons and synaptic endings.     

Empirically supported treatments: Implications for training.

This article discusses the role of empirically supported treatments (ESTs) in the training of clinical psychologists. Training in ESTs can be integrated in ways that vary depending on the level of training and setting. Predoctoral programs, internships, postdoctoral programs, and continuing education are discussed in regard to special challenges and sequencing of training. A preliminary set of guidelines for training in ESTs is suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Factors in the modification by isolation of electroconvulsive shock-produced retrograde amnesia in the rat.

Cites earlier research which demonstrated that placing rats in a sensory-restricted environment during the electroconvulsive shock- (ECS) retention interval following 1-trial appetitive learning will prevent or eliminate ECS-produced retrograde amnesia. Exp I replicated this finding using 32 male Dublin albino rats in a 1-trial aversive learning task, indicating that this effect is not task specific. Exp II attempted to determine whether illumination or the restricted environment was the crucial factor in this phenomenon. 64 male Sprague-Dawley rats placed in the light during the ECS-retention interval, whether restricted or in the colony, demonstrated retrograde amnesia after ECS. However, Ss left in the dark during this interval demonstrated little, if any, retention deficit particularly if this condition was combined with sensory isolation. These studies further indicate that manipulation of S's general environment after ECS can alter ECS-produced retention losses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Embracing and Resisting Romantic Fantasies as the Rhetorical Vision on a SeniorNet Discussion Board

A fantasy theme analysis of a SeniorNet discussion board found participants simultaneously embracing and resisting the relationships constructed in traditional romance narratives. The rhetorical vision that emerged illustrates how life-span conditions facilitate talk about romantic relationships. Three fantasies coalesced to construct the rhetorical vision "good men are hard to find": the knight in shining armor, searching for a bargain, and fishing for men. Through these fantasies, the rhetorical community resisted female subordination found in traditional romance narratives while embracing the need for love, partnership, and physical intimacy. As the heroines in these fantasies, women were constructed as independent, vital, and fulfilled, yet wanting to find heterosexual partnerships. The heroes upheld this construction of "woman," while the villains infringed upon females' valued independence. In this way, narratives that evidenced the struggle over the meaning of romance were tools for the participants' empowerment.     

A longitudinal examination of fear reactions in victims of rape.

Investigated fear reactions in rape victims for 1 yr following their assaults. 150 female victims, over 15 yrs of age, seen approximately 2 wks after the assault and at 1, 2, 4, 8, and 12 mo postrape, were compared with a matched control group of nonvictims seen at the same intervals. To control for the effects of repeated testing, 3 additional groups of victims were assessed only once at either 2, 4, or 8 mo postrape. All participants completed the Modified Fear Survey Schedule (MFS), which yielded a total fearfulness index as well as 6 subscale scores: rape fears, animal fears, classical fears, social–interpersonal fears, tissue-damage fears, and miscellaneous fears. Following the assault, victims were significantly more fearful than nonvictim controls as indicated by their overall MFS score and most of the subscale scores. Although their overall fearfulness declined somewhat and stabilized by 2 mo postassault, victims remained significantly more fearful than nonvictim controls at 12 mo postassault. The rape fears and classical fears subscales seemed to contribute most to this elevation. Results from the single-testing victim groups indicated that repeated assessment had no effect on participants' scores. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A fourier theory for cast shadows

Cast shadows can be significant in many computer vision applications, such as lighting-insensitive recognition and surface reconstruction. Nevertheless, most algorithms neglect them, primarily because they involve nonlocal interactions in nonconvex regions, making formal analysis difficult. However, many real instances map closely to canonical configurations like a wall, a V-groove type structure, or a pitted surface. In particular, we experiment with 3D textures like moss, gravel, and a kitchen sponge, whose surfaces include canonical configurations like V-grooves. This paper takes a first step toward a formal analysis of cast shadows, showing theoretically that many configurations can be mathematically analyzed using convolutions and Fourier basis functions. Our analysis exposes the mathematical convolution structure of cast shadows and shows strong connections to recent signal-processing frameworks for reflection and illumination.
