Scholars have recently explored the effects of salespeople's intraorganizational relationships on salespeople's job-related outcomes. Grounded in social influence theory, we explore the effects of salespeople's intraorganizational skills on salesperson relationship performance. We empirically tested the proposed relationships using the data from a non-Western sales force working with an organization in an emerging economy. The results indicate that salespeople's political skill positively contributes to salespeople's identification with the organization and to creative performance, while strikingly, we also find that salesperson task adaptivity weakens these effects. Moreover, salespeople's identification and creative performance are positively related to customer satisfaction. These findings demonstrate that salespeople's intraorganizational relationships play a key role in enhancing customer satisfaction. In light of these results, we explore implications for marketers and academics and conclude by suggesting directions for further research.  相似文献

As human activity and interaction increasingly take place online, the digital residues of these activities provide a valuable window into a range of psychological and social processes. A great deal of progress has been made toward utilizing these opportunities; however, the complexity of managing and analyzing the quantities of data currently available has limited both the types of analysis used and the number of researchers able to make use of these data. Although fields such as computer science have developed a range of techniques and methods for handling these difficulties, making use of those tools has often required specialized knowledge and programming experience. The Text Analysis, Crawling, and Interpretation Tool (TACIT) is designed to bridge this gap by providing an intuitive tool and interface for making use of state-of-the-art methods in text analysis and large-scale data management. Furthermore, TACIT is implemented as an open, extensible, plugin-driven architecture, which will allow other researchers to extend and expand these capabilities as new methods become available.  相似文献

This study assessed whether a boy with profound multiple disabilities and minimal motor behavior could learn to use a new response-microswitch combination to control environmental stimulation. The response selected was a chin movement; a mechanical microswitch was set up for this response. The boy learned to use the microswitch, increasing the frequency of the chin response and the level of pleasant stimulation following such response. The performance was retained at a 2-mo. post-intervention check.  相似文献

Technological aids such as microswitches may be critical to foster learning and development in children with multiple disabilities. In study I, a child with minimal motor behavior was provided with a microswitch for chin movements to assess whether he could learn to use these movements to activate environmental stimuli. In study II, a child with dystonic (difficult-to-control) behavior was provided with microswitches for two motor responses and two vocal utterances. We wanted to assess whether he could use both types of responses effectively (varying within each pair, consistent with choice performance). The results were highly encouraging with both children. In study I, there was a significant increase in the childs responding, suggesting learning and contingency awareness. In study II, there was a significant increase in responding as well as response variation that suggested choice behavior. The importance of microswitch devices in promoting new learning/developmental objectives and improving quality of life is discussed.  相似文献

The use of Ritalin and other stimulant drug treatments for attention-deficit hyperactivity disorder (ADHD) raises distinctive moral dilemmas for parents; these moral dilemmas have not been adequately addressed in the bioethics literature. This paper draws upon data from a qualitative empirical study to investigate parents' use of the moral ideal of authenticity as part of their narrative justifications for dosing decisions and actions. I show that therapeutic decisions and actions are embedded in valued cultural ideals about masculinity, self-actualization and success, as well as in moral conceptions of authenticity and personal freedom. I argue that this investigation of parents' moral justifications and dosing dilemmas raises questions about the validity of authenticity as a transcendent moral principle. Moreover, this study demonstrates that in order to be relevant, bioethical analysis of neurocognitive enhancement must engage with ground-up studies of moral principles and decision-making in context.  相似文献

Theories of perceptual transparency have typically been developed within the context of a physical model that generates the percept of transparency (F. Metelli's episcotister model, 1974b). Here 2 fundamental questions are investigated: (a) When does the visual system initiate the percept of one surface seen through another? (b) How does it assign surface properties to a transparent layer? Results reveal systematic deviations from the predictions of Metelli's model, both for initiating image decomposition into multiple surfaces and for assigning surface attributes. Specifically, results demonstrate that the visual system uses Michelson contrast as a critical image variable to initiate percepts of transparency and to assign transmittance to transparent surfaces. Findings are discussed in relation to previous theories of transparency, lightness, brightness, and contrast-contrast.  相似文献

Previous work indicates that there may be a relationship between the observation and evaluation of one's physique and the construct of social physique anxiety associated with this process. Since physical educators are expected to serve as role models of desired fitness behaviors, bodily appearance, and composition, it is of interest to examine whether such responses and relationships may be observed. However, there is limited published information on anthropometric profiles and body images of physical education professionals, especially of those from India. Therefore, this study compared anthropometric profiles and Social Physique Anxiety in a sample of 182 male physical education professionals from India (M age=41.2 yr.). Body Mass Index, sum of three skinfolds (Tricep, Abdomen, and Thigh), and waist/hip ratio were determined using standard procedures. The sample was grouped into overweight and normal weight categories. Significant group differences were found for the sum of skinfolds and waist/hip ratio, with no significant differences between groups on the Social Physique Anxiety total score. Correlations for the anthropometric measures with the Social Physique Anxiety scores indicated no significant relationships. Mean total Social Physique Anxiety score for the combined group was comparable to those reported for other groups of physically active individuals. These findings indicate low Social Physique Anxiety in this sample and may have implications with regard to the attitudes pertaining to body image and role modeling of appropriate fitness behaviors.  相似文献

Eight patients (seven women), mean +/- SD T1 age 68.57 +/- 12.43 years, average educational level 5.83 +/- 3.70 years, had two Tc-99m ECD SPECT examinations separated by an average 8.49 +/- 5.59 months. Patients were imaged using standard Harlem Hospital acquisition and processing protocols with approximately 30 mCi of ECD on a Prism 3000 triple head gamma camera. Images were interpreted by an independent reader blinded to the patients' clinical history and imaging date. T1 psychiatric diagnosis was seven Alzheimer's dementia (AD) and one depression. Eight T1 images were interpreted as abnormal, six indicative of AD. Binomial 95% two-tail confidence interval for T1 agreement between diagnosis and interpretation was 0.25 0.63 0.92. T2 diagnosis was seven AD and one none. Seven T2 images were abnormal and indicative of AD, and one was normal. T2 confidence interval was 0.34 0.75 0.97. These findings suggest SPECT's value in assessing AD in uneducated socioeconomically disadvantaged geriatric patients.  相似文献

Left- and right-handed school children with differing reading/writing experiences (unidirectional left-to-right vs bidirectional) were asked to draw 3-cm lines from right-to-left or from left-to-right with each hand. With either hand, lines drawn from left to right were more accurate than those drawn from right to left, particularly for right-handed left-to-right users; bidirectional readers showed no directional bias. Moreover, bidirectional readers were more accurate than unidirectional readers. The findings support a greater influence of directional scanning effects than handedness on the task of line length estimation.  相似文献
