One key property in recommender systems is the long-tail distribution user-item interactions where most items only have few user feedback. Improving recommendation of tail can promote novelty and bring positive effects to both users providers, thus a desirable systems. Current novel studies over-emphasize importance without differentiating degree users' intent on popularity often incur sharp de...

Temporal relational modeling in video is essential for human action understanding, such as recognition and segmentation. Although Graph Convolution Networks (GCNs) have shown promising advantages relation reasoning on many tasks, it still a challenge to apply graph convolution networks long sequences effectively. The main reason that large number of nodes (i.e., frames) makes GCNs hard capture ...

This paper describes two complementary mechanisms for the supervision of large scale and highly distr ibuted systems structured as a cloud of autonomic computing components. The fi rst one is based on the creation of supervision pervasions, for the supervision of clusters of components (i.e., aggregates structurally organized through one or several contracts) implementing specific services in a...

Background. Tuberculosis is a major public health problem in South Africa, made worse by poor adherence to and frequent interruption of treatment. Direct observation (DO) of tuberculosis patients taking their drugs is supposed to improve treatment completion and outcome. We compared DO with self-supervision, in which patients on the same drug regimen are not observed taking their pills, to asse...

The authors take the genogram, a classic supervision method used to address the self-of-the-therapist, and tweak it by highlighting the cultural influences on supervisees. (See Chapter 10 in the accompanying book for the initial development and purposes of the genogram and Chapter 3 for ways it is now used to assess cultural equity.) After illustrating the value of the cultural genogram for sup...

Narcissistic leaders are self-absorbed and hold beliefs of entitlement and superiority. Their aggressive tendencies in the face of criticism and inclinations to validate their selfworth by derogating others may lead others to perceive them as being abusive. Here, we test the relationship between leader narcissism and followers’ perceptions of abusive supervision. Drawing upon research related t...

Single-mother, single-father, and intact families from homes ranging from low to high supervision are compared to determine the effects of family structure and parent supervision on adolescent alcohol use, illicit drug use, and delinquency. Using adolescent self-reports, scores were derived for adolescent problem behaviors and rates of supervision by resident parent(s). Results indicate that su...
