Video recordings of 11 rats were digitized at five frames per second, and parameters describing the shape and the position of the rat were calculated. The behavior displayed by the rats was observed by an experienced observer. Separate neural networks were trained and validated, using the data for each individual rat. The neural networks correctly classified an average of 76.53% of the frames in the validation set and 98.18% of the frames in the training set. A single neural network was trained with 6 rats and validated with 5 rats. The neural network correctly classified 63.74% of the frames in the validation set and 82.85% of the frames in the training set. 相似文献

Purpose The purpose of this study was to investigate the relationship between counterproductive behaviors (CPBs) and psychological
well-being in a teamwork setting. Moreover, we examined the moderating effect of task interdependence. CPBs are considered
in light of four dimensions, namely parasitism, interpersonal aggression, boastfulness, and misuse of resources.
Design/Methodology/Approach Data were collected from a sample of 249 individuals working in a Canadian prison. The study was based on two measurement
times.
Findings The results reveal that the four dimensions of CPBs are negatively related to psychological well-being and that relationships
involving interpersonal aggression and boastfulness are moderated by task interdependence.
Implications This study highlights the importance for managers to identify the presence of CPBs in their team as soon as possible so as
to be able to remedy them before they affect team members’ psychological well-being. Moreover, interpersonal aggression and
boastfulness may be particularly detrimental in a context of high interdependence.
Originality/Value This study further extends the nomological network of CPBs. Indeed, the results indicate that the presence of CPBs may harm
employees’ mental health. Furthermore, this study shows that a contextual characteristic (i.e., task interdependence) may
amplify the detrimental effect of some CPBs.

The first goal of this study was to investigate whether levels of overparenting behavior (anticipatory problem-solving, advice/affect management, tangible assistance, and low levels of child self-direction) differ depending on the context (Arab-Israeli vs. Jewish-Israeli; mothers vs. fathers). Second, we considered whether the association between overparenting and young adults’ interpersonal sensitivity depends on those contexts. Questionnaires were collected from 165 triads (mothers, fathers, and young adults), of which 89 were Jewish-Israeli and 76 Arab-Israeli. Parents reported on their overparenting behaviors and young adults reported on their interpersonal sensitivity. Results indicated that all four dimensions of overparenting behaviors were more prominent in Arab-Israeli culture than in Jewish-Israeli culture, while advice/affect management was lower for mothers than for fathers and fathers provided more child self-direction than mothers. In addition, higher levels of anticipatory problem-solving were significantly associated with higher levels of young adult interpersonal sensitivity, independent of parental gender or cultural background, supporting the general negative association between anticipatory problem-solving and interpersonal sensitivity. 相似文献

In order to provide insights into why discrimination protocols with three stimuli sometimes tend to be less sensitive than protocols with two stimuli, two experiments were conducted. In these experiments, the relative effects of memory decay and memory interference were investigated. Both experiments involved purified water and/or solutions of low NaCl concentration. In Experiment 1, three protocols were compared: the traditional same-different test (Protocol 1), the same protocol with a rinse between the two samples (Protocol 2), and Protocol 2 with an added time delay between the first sample and the intermediate rinse (Protocol 3.) The decrease in measured d' values as time delay increased indicated that memory decay might be a factor for tests with three stimuli, such as the triangle method, rendering it less sensitive than tests with two stimuli, such as the same-different method. In Experiment 2, four protocols were compared: the traditional same-different test, the two-rinse same-different test, the triangle test, and what will be called duo same-different test. The experimental design allowed the individual consideration of memory decay and interference effects. From this last experiment, the substantial effect of memory interference was uncovered. Further experimentation will be necessary to estimate the exact relative effects of memory interference and memory decay. 相似文献
