TL;DR: A descriptive framework for understanding factors that influence the success of knowledge management (KM) initiatives in an organization is introduced and identifies three main classes of influencing factors and characterizes the individual factors in each class.
Abstract: Modern organizations are increasingly seen as knowledge-based enterprises in which proactive knowledge management is important for competitiveness. This paper introduces a descriptive framework for understanding factors that influence the success of knowledge management (KM) initiatives in an organization. It identifies three main classes of influencing factors (managerial, resource, and environmental) and characterizes the individual factors in each class. A Delphi process was used to develop and assess the framework. The Delphi panel was comprised of 31 recognized researchers and practitioners in the KM field. The resultant framework can be used by researchers for KM issue and hypothesis generation, by practitioners for benchmarking KM practices, and by educators for helping organize the study of KM.

TL;DR: The data suggest that sphingosine kinase is a prototypical member of a new class of lipid kinases, and an important step in corroborating the intracellular role of SPP as a second messenger.

TL;DR: A view-based approach to recognize humans from their gait by employing a hidden Markov model (HMM) and the statistical nature of the HMM lends overall robustness to representation and recognition.
Abstract: We propose a view-based approach to recognize humans from their gait. Two different image features have been considered: the width of the outer contour of the binarized silhouette of the walking person and the entire binary silhouette itself. To obtain the observation vector from the image features, we employ two different methods. In the first method, referred to as the indirect approach, the high-dimensional image feature is transformed to a lower dimensional space by generating what we call the frame to exemplar (FED) distance. The FED vector captures both structural and dynamic traits of each individual. For compact and effective gait representation and recognition, the gait information in the FED vector sequences is captured in a hidden Markov model (HMM). In the second method, referred to as the direct approach, we work with the feature vector directly (as opposed to computing the FED) and train an HMM. We estimate the HMM parameters (specifically the observation probability B) based on the distance between the exemplars and the image features. In this way, we avoid learning high-dimensional probability density functions. The statistical nature of the HMM lends overall robustness to representation and recognition. The performance of the methods is illustrated using several databases.

TL;DR: For instance, this paper found that repetitive thought was positively correlated with anxiety and depression in students and negatively correlated with depression in patients, respectively, in a study with over 1000 participants.
Abstract: Worry and depressive rumination have both been described as unproductive, repetitive thought which contributes to anxiety or depression, respectively. It was hypothesized that repetitive thought, rather than its specific forms, is a general concomitant of negative mood. Study 1 was a cross-sectional test of the hypothesis. Repetitive thought was positively correlated with anxiety and depression in students (n = 110). In patients (n = 40), repetitive thought was positively correlated with anxiety and depression, and rumination was also specifically correlated with depression. Study 2 was a prospective test of the hypothesis. In students (n = 90), there were significant cross-sectional relationships between repetitive thought and both anxiety and depression. In addition, repetitive thought at least partially predicted maintenance of anxious symptoms. Phenomena such as goal interruption, failures of emotional processing, and information processing may lead to repetitive thought which increases negative mood states, including both anxiety and depression.

TL;DR: Huebner et al. as mentioned in this paper investigated the characteristics of adolescents who report high levels of life global satisfaction and found that high life satisfaction is associated with some mental health benefits that are not found among youth reporting comparatively lower satisfaction levels.
Abstract: This study investigated the characteristics of adolescents who report high levels of life global satisfaction. A total of 485 adolescents completed the Students’ Life Satisfaction Scale (SLSS) (Huebner, E. S. (1991). Sch. Psychol. Int. 12: 231–240.) along with self-report measures of intrapersonal, interpersonal, and school-related functioning. Based on their SLSS scores, students were divided into three groups: “low” (bottom 20% of the distribution), “average” (middle 50%), and “high” (upper 20%). Youth in the high satisfaction group reported significantly higher adaptive functioning on all dependent variables than youth in the low satisfaction group. Relative to students with average life satisfaction, students with high life satisfaction reported superior scores on a measure of social stress, a measure of attitudes toward teachers, and on all measures of intrapersonal functioning. Also, no adolescents in the high life satisfaction group demonstrated clinical levels of psychological symptoms, whereas 7% of the average group and 42% of the low satisfaction group reported clinical levels of symptoms. Taken together, the findings suggested that high life satisfaction is associated with some mental health benefits that are not found among youth reporting comparatively lower satisfaction levels.
