Conclusions Continued scientific and medical progress in Central and Eastern Europe depends on the development of an atmosphere that is
conducive to implementing the changes that are necessary to bring better health and longer lives for everyone. Privatization
and commercialization are threatening the objectivity of clinical research and the availability of health care because uncontrolled
market mechanisms focused on profit are nurturing conflict of interest that generate bias and unreliability into research
and medicine. Changes are needed that address the following:

– | administrative procedures for responding to the conflict of interest problem. |

The allocation of overt visual attention is investigated in a multi-task and dynamical situation: driving. The Expectancy–Value model of attention allocation stipulates that visual exploration depends on the expectancy and the value of the task-related information available in each Area Of Interest (AOI). We consider the approach to an intersection as a multi-task situation where two subtasks are involved: vehicle control and interactions with other drivers. Each of these subtasks is associated with some specific visual information present in the associated AOIs: the driver’s lane and the intersecting road at the intersection. An experiment was conducted in a driving simulator, coupled with a head-mounted eye-tracker. The intersecting road’s AOI’s Expectancy was manipulated with the traffic density, and its Value was manipulated with the priority rule before the intersection (stop, yield, and priority). The distribution of visual attention and the dynamics of visual exploration were analyzed on 20 participants, taking into account the dwell time in the AOIs associated to the driving subtasks, and the gaze transitions between the AOIs. The results suggest that visual attention to intersecting roads varied with the priority rule, and impacted the visual attention associated with the vehicle control subtask. In addition, a quantitative model was used to improve the understanding of the Expectancy and Value factors. The comparison of the data with the model’s predictions enables quantifying the observed differences between the experimental factors. Finally, the results associated with the traffic density are discussed in relation to the nature of the relevant information while approaching the intersection. 相似文献

Due to the progression in computer vision technology, object recognition systems have gained considerable research interest. Though there are numerous object recognition systems in the literature, there is always a constant demand for better object recognition systems. Taking this as a challenge, this work proposes a novel object recognition system based on points of interest and feature extraction. Initially, the points of interest of the image are selected by means of Derivative Kadir-Brady (DKB) detector and the neighbourhood pixels of a particular window size are selected for further processing. The gabor and curvelet features are extracted from the area of interest, followed by the Support Vector Machine (SVM) classification. The performance of the proposed object recognition system is evaluated against three analogous techniques in terms of accuracy, precision, recall and F-measure. On experimental analysis, it is proven that the proposed approach outperforms the existing approaches and the performance of the proposed work is satisfactory. 相似文献

Apathy is frequently described in patients with traumatic brain injury (TBI); its negative consequences particularly affect functional independence. Among apathetic manifestations, lack of initiative and lack of interest have mainly been associated with cognitive impairments. However, few studies have been conducted to precisely identify the underlying cognitive processes. Our aims were (1) to determine the best predictor of apathy from among several cognitive processes, including episodic memory and attention/executive mechanisms and multitasking, and (2) to examine to what extent multitasking could mediate the relationships between specific cognitive processes and lack of initiative/interest. Seventy participants (34 patients with TBI matched with 36 control participants) were given a questionnaire to assess anxio‐depressive symptoms, four tasks to assess specific cognitive processes, and one task to assess real‐life multitasking. Participants’ relatives completed an apathy questionnaire. Multitasking, as assessed by the number of goals not achieved, was the only significant predictor of apathetic manifestations. In addition, the mediation analyses revealed that multitasking performance mediated the relationships between verbal episodic memory and lack of initiative/interest, whereas executive and attentional functions were only indirectly related to lack of initiative/interest due to their significant impacts on multitasking. These results shed new light on the aetiology of apathetic manifestations in patients with TBI, indicating how specific cognitive deficits are expressed in real‐life multitasking, and consequently, how they may lead to the development and/or maintenance of apathetic manifestations. 相似文献

The institutionalization of biodiversity conservation through legal instruments has led to mixed reactions at both the individual and community levels, with conflict and resistance co‐existing with support. The overall purpose of this paper is to describe how rural communities living in areas included in the Natura 2000 Network of protected sites, where local practices of land use are regulated by new legal directives, receive biodiversity conservation goals. Previous studies suggest that this reception is strongly shaped by place identification, but their contradictory results demand further clarification. This study examines the role of psycho‐social variables identified by previous studies as potentially relevant moderators of identification: (a) Vested interest in natural resources, (b) evaluation of the designation process of protected areas and (c) institutional trust. It further extends previous research by analysing the support given to contextually relevant ecological practices. Results reveal a positive link between place identification and attitudes in the high vested interest condition and show that support for conservation practices is better predicted in the high vested interest and low trust conditions. The discussion focuses on the relevance of analysing contextually relevant psycho‐social moderators when attempting to understand how local communities' relation with biodiversity conservation is affected by legislative innovation.

In this commentary, the two critical attributes of seductive details are described through a historical lens: relevance and interest. For each of these attributes, various forms that have populated the seductive detail literature are distinguished, and the specific manner in which each is interpreted by contributors to the Special Issue is considered. The forms of relevance overviewed are personal, structural, instructional, and task relevance. For interest, distinctions between individual and situational interest are noted, and the concept of interestingness is delineated. With this historical backdrop, the studies in this Special Issue are analyzed, and four provocative questions are posed: When are “seductive details” not seductive? What contextual factors contribute to seduction? For whom is seduction a problem? When is the solution worse than the problem? 相似文献

职业兴趣的结构:理论与研究 总被引:6,自引:0,他引:6
有着近70年历史的职业兴趣结构的研究丰富与发展了其理论,这些理论主要包括:Roe的圆形模型、Holland的六边形模型、Prediger的维度模型、Gati的层级模型以及Tracey-Rounds的球形模型。总结比较这些不同的职业兴趣结构的研究发现,Holland的六边形模型更适合于美国样本(非种族样本)群体,而其他的模型则有待于进一步的考察。研究还表明没有广泛适用的职业兴趣模型,因此,职业兴趣的跨化研究应深入探讨与验证。 相似文献

This longitudinal study examines the role that students' political reputation in class plays in their future political activities offline together with other people. When aged 16, students were asked to nominate the classmates they considered politically knowledgeable and verbal in class, that is, as having a political reputation. This measure of political reputation was used to predict the participants' political activities offline four years later at age 20 and their attempts to take a stand in public in the national election the same year. The study controlled for individual differences in political interest, self-perceived political impact in class, the students' political activities at age 16, and also gender and immigrant status. About 300 Swedish students were followed up four years later. Political reputation in class positively predicted future political activities offline, membership of political organizations, and attempts to take a stand in public for a party in the forthcoming national election. At the same time, the role played by political reputation depended upon students' other characteristics, especially their levels of anger and popularity, as observed by classmates. Evidently, the group dynamics in class that give some students a political reputation have long-term consequences for their future political activities. 相似文献
