Servant leadership and serving culture: Influence on individual and unit performance

Abstract: In a sample of 961 employees working in 71 restaurants of a moderately sized restaurant chain, we investigated a key tenet of servant leadership theory—that servant leaders guide followers to emula...

Literature review of the usefulness of nerve conduction studies and electromyography for the evaluation of patients with carpal tunnel syndrome. AAEM Quality Assurance Committee

Abstract: The sensitivity and specificity of nerve conduction studies (NCS's) and electromyography (EMG) for the diagnosis of carpal tunnel syndrome (CTS) were evaluated by a critical review of the literature. With a search of the medical literature in English through May 1991, 165 articles were identified and reviewed on the basis of six criteria of scientific methodology. The findings of 11 articles that met all six criteria and the results of 48 additional studies that met four or five criteria are presented. We concluded that median sensory and motor NCS's are valid and reproducible clinical laboratory studies that confirm a clinical diagnosis of CTS with a high degree of sensitivity and specificity. Clinical practice recommendations are made based on a comparison of the sensitivities of the several different median nerve conduction study (NCS) techniques.

Cross-Cultural Variations in Predictors of Life Satisfaction: Perspectives from Needs and Values

Abstract: The authors tested for cross-cultural difference in predictors of life satisfaction. In Study 1 (39 nations, N = 54, 446), they found that financial satisfaction was more strongly associated with life satisfaction in poorer nations, whereas home life satisfaction was more strongly related to life satisfaction in wealthy nations. In Study 2 (39 nations, N = 6,782), the authors found that satisfaction with esteem needs (e.g., the self and freedom) predicted global life satisfaction more strongly among people in individualist nations than people in collectivist nations. The present investigation provides support for the needs and values-as-moderators model of subjective well-being at the cultural level. The need for theories that account for culture-specific as well as universal predictors of life satisfaction will be discussed.

Sparse Representation for Signal Classification

Abstract: In this paper, application of sparse representation (factorization) of signals over an overcomplete basis (dictionary) for signal classification is discussed. Searching for the sparse representation of a signal over an overcomplete dictionary is achieved by optimizing an objective function that includes two terms: one that measures the signal reconstruction error and another that measures the sparsity. This objective function works well in applications where signals need to be reconstructed, like coding and denoising. On the other hand, discriminative methods, such as linear discriminative analysis (LDA), are better suited for classification tasks. However, discriminative methods are usually sensitive to corruption in signals due to lacking crucial properties for signal reconstruction. In this paper, we present a theoretical framework for signal classification with sparse representation. The approach combines the discrimination power of the discriminative methods with the reconstruction property and the sparsity of the sparse representation that enables one to deal with signal corruptions: noise, missing data and outliers. The proposed approach is therefore capable of robust classification with a sparse representation of signals. The theoretical results are demonstrated with signal classification tasks, showing that the proposed approach outperforms the standard discriminative methods and the standard sparse representation in the case of corrupted signals.

Life skills development through sport: current status and future directions

Abstract: This review is designed to summarize and critique current life skills through sport research. In particular, life skills are defined, the conditions needed to examine life skills development are explored, and the possible theoretical explanations of how, when, under what conditions and why life skills develop in sport participants are discussed. A heuristic model of coaching life skills is offered. To conclude, future research directions are forwarded and include the need for: (a) quantitative and qualitative research; (b) the development of valid life skills through sport measures; (c) an examination of sport program type differences; (d) evaluation research; (e) longitudinal studies; (f) studies focusing on identifying theoretical explanations for the life skill development sport participation link; (g) the utilization of experimental designs; and (h) an examination of the transferability of life skills. The importance of conducting this type of research for both theoretical and practical reasons is emp...
