In a cross sectional study on a purposive sample, Kumar et al.(2001) assessed the re la t ionsh ip be tween psychosocial variables, subsyndromal affective psychopathologv, and psychosocial functioning in 68 bipolar patients stabilized on prophylactic lithium. They found that higher daily hassles and life events scores were associated with higher depression ratings, while lower perceived social ...

AIM To determine the predominant learning style preferences of undergraduate nursing students. METHOD A demographic questionnaire and Honey and Mumford's (2000a) learning styles questionnaire were administered to a purposive sample of 136 students. RESULTS A response rate of 81% (110) was obtained. The results are congruent with U.K. studies, which show that the reflector is the preferred l...

Methods Qualitative research was considered most appropriate to understand the attitudes and beliefs of rural women. Semi-structured, one to one interviews were conducted on 12 participants; 4 pregnant women/delivered within 1 year, 4 SBAs and 4 FCHVs/TBAs to gauge a variety of opinions. A purposive approach was used as well as convenience sampling and snowball sampling from the district hospit...

Recent studies in the monkey suggest that the subthalamic nucleus (STN) is involved in control of eye movement, yet its functional significance in humans is unknown. Saccadic eye movements were studied in eight parkinsonian patients treated by bilateral electrical stimulation of the STN. STN stimulation improved the accuracy of memory guided saccades but not of reflexive visually guided saccade...

3-D object recognition involves using image-computable features to identify 3-D object. A single view of a 3-D object may not contain sufficient features to recognize it unambiguously. One needs to plan different views around the given object in order to recognize it. Such a task involves an active sensor – one whose parameters (external and/or internal) can be changed in a purposive manner. In...

{ We describe a set of visual behaviors developed over the years, in the general context of robot navigation. The rst set of behaviors solve three basic problems in vehicle navigation: obstacle avoidance, docking to a surface and moving along corridors or walls. Another set of visual behaviors were developed for the active stereo head Medusa, with the purpose of tracking objects with arbitrary ...

Academic procrastination is defined as a purposive delay of academic tasks that must be completed. Within the framework of the ecological model of resiliency, this study examined how ecological assets were related to academic procrastination among adolescents. Participants in the study were 577 adolescents (53.5% boys) from Shanghai, China. They completed measures of ecological assets, commitme...

The goal of this phenomenological study was to explore what within the lived experiences of exemplary oncology nurses facilitates the avoidance of compassion fatigue. A purposive sample of seven oncology nurses (RNs) who were identified by their colleagues as exemplary caregivers was recruited. Data were collected through semi-structured conversations that were subsequently transcribed. Transcr...

Reinforcement learning is a useful method to acquire a purposive behavior with little or no a priori knowledge about the environment. In applying the reinforcement learning to a real robot, there are many di cult problems, such as long learning time and construction of its state and action space. In this paper, we show a soccer robot which learns to shoot a ball into the goal using the Q-learni...

In this paper, we describe the implementation of a heterogeneous cooperative multi-robot system that was designed with a goal of engineering a grounded symbolic representation in a bottom-up fashion. The system comprises two autonomous mobile robots that perform cooperative cleaning. Experiments demonstrate successful purposive navigation, map building and the symbolic communication of location...
