The effect of exercise on depressive symptoms in the moderately depressed elderly.

Abstract: Thirty community-dwelling, moderately depressed elderly were randomly assigned to 1 of 3 interventions: experimenter-accompanied exercise in the form of walking, a social contact control condition, and a wait-list control. Exercise and social contact both resulted in significant reductions in both the total and the psychological subscale of the Beck Depression Inventory (BDI). The exercise condition, however, unlike the control conditions, resulted in decreased somatic symptoms of the BDI. These results indicate that, at least in the short term, exercise has a broader effect compared with control conditions in reducing depressive symptoms in the moderately depressed elderly.

Failure Prognosis and Applications—A Survey of Recent Literature

Abstract: Fault diagnosis and prognosis are some of the most crucial functionalities in complex and safety-critical engineering systems, and particularly fault diagnosis, has been a subject of intensive research in the past four decades. Such capabilities allow for detection and isolation of early developing faults as well as prediction of fault propagation, which can allow for preventive maintenance, or even serve as a countermeasure to the possibility of catastrophic incidence as a result of a failure. Following a short preliminary overview and definitions, this article provides a survey of recent research on fault prognosis. Additionally, we report on some of the significant application domains where prognosis techniques are employed. Finally, some potential directions for future research are outlined.

Large vocabulary off-line handwriting recognition: A survey

Abstract: Considerable progress has been made in handwriting recognition technology over the last few years. Thus far, handwriting recognition systems have been limited to small and medium vocabulary applications, since most of them often rely on a lexicon during the recognition process. The capability of dealing with large lexicons, however, opens up many more applications. This article will discuss the methods and principles that have been proposed to handle large vocabularies and identify the key issues affecting their future deployment. To illustrate some of the points raised, a large vocabulary off-line handwritten word recognition system will be described.

The development of a questionnaire for predicting online learning achievement

Abstract: The study reported here concerns the development and predictive validation of an instrument to assess the achievement outcomes of DE/online learning success. A 38‐item questionnaire was developed and administered to 167 students who were about to embark on an online course. Factor analysis indicated a four‐factor solution, interpreted as “general beliefs about DE,” “confidence in prerequisite skills,” “self‐direction and initiative” and “desire for interaction.” Using multiple regression we found that two of these factors predicted achievement performance (i.e., Cumulative Course Grade). Comparisons of pretest and posttest administrations of the questionnaire revealed that some changes in opinion occurred between the beginning and the end of the course. Also, categories of demographic characteristics were compared on the four factors. The overall results suggest that this instrument has some predictive validity in terms of achievement, but that Cumulative Grade Point Average (i.e., the university's record...

Popularity, friendship, and emotional adjustment during early adolescence.

Abstract: The authors propose that popularity and friendship are linked to different forms of adjustment and emotional well-being. A central point of their model is that friendship functions as an important mediator between popularity and loneliness in early adolescence.
