Urban mobility has been severely impacted by the coronavirus pandemic, with public transport (PT) particularly affected due to infection risks and fears. The promotion of alternative modes of transport such as bike sharing systems (BSS) has gained a new drive as a possible way of providing an alternative to PT and limit a potential surge in private car use.In this study, we provide insights on the motivations for using bike sharing during the COVID-19 pandemic through a survey to the BSS users of Lisbon (entitled GIRA). Before the coronavirus pandemic, the most influential motivations were those connected to the BSS’ Service Coverage & Quality (such as the convenient location of BSS stations near the users’ destinations or the availability of shared e-bikes) as well as to the Personal Interests & Well-being of BSS users (namely the pleasure of cycling as well as the perceived environmental and health benefits). With the emergence of the COVID-19 pandemic, although the motivations of Service Coverage & Quality continue to be the most valued by respondents, the motivations associated with using BSS to avoid PT and to maintain a social distance during the trip are now as important as the motivations linked to Personal Interests & Well-being. Furthermore, new users who have joined bike sharing during COVID-19 give more importance to the Social Influence (such as seeing other people using the system or the influence of their social circle) comparatively to those who were already users before the pandemic and continue to use BSS.This research provides evidence on the importance of bike sharing to the resilience of urban transport systems, particularly during disruptive public health crises. It supports that BSS should continue to operate during the coronavirus pandemic as such systems offer a transport alternative to PT that is perceived to be capable of preserving a physical distance.  相似文献

In works of Eleanor Rosch “natural” concepts was introduced that reflect a high correlated structure of features of objects of the external world. Prototypes of the “natural” concepts are clearest cases of objects that reflect this highly correlated structure. The same high correlated structure manifested in the “natural” phenotypical classification. To formalize this highly correlated structure, we define a special type of probabilistic causal relations and then probabilistic formal concepts as a cyclically connected probabilistic causal relations. Based on these definitions, we developed a method of prototypes discovery and illustrate it on the example of digits’ prototypes discovery.  相似文献

Physical exercise is an effective tool for improving public health, but the general population exercises too little. Drawing on recent theorizing on the combined role of boredom and self-control in guiding goal-directed behavior, we test the hypothesis that individual differences in boredom and self-control differentiate high from low exercisers. The role of boredom as a non-adaptive disposition is of particular interest, because research on boredom in sports is scarce. Here, we investigate the role of such individual differences in self-reported weekly exercise behavior (in minutes) in a sample of N = 507 participants (n = 200 female, Mage = 36.43 (±9.54)). We used the robust variant of Mahalanobis distance to detect and remove n = 51 multivariate outliers and then performed latent profile analysis to assess if boredom (boredom proneness; exercise-related boredom) and self-control (trait self-control; if-then planning) combine into identifiable latent profiles. In line with theoretical considerations, the Bayesian Information Criterion favored a solution with two latent profiles. One profile was characterized by higher-than-average exercise-related boredom and boredom proneness and lower-than-average self-control and if-then planning values. This pattern was reversed for the second profile. A one-sided Bayesian two-sample t-test supported the hypothesis that the first profile is associated with less exercise behavior than the second profile, BF = 16.93. Our results foster the notion of self-control and if-then planning as adaptive dispositions. More importantly, they point to an important role of boredom in the exercise setting: exercise-related boredom and getting easily bored in general are associated with less exercise activity. This is in line with recent theorizing on boredoms' and self-controls’ function in guiding goal-directed behavior.  相似文献

ObjectivesDespite a growing body of literature on athletes' migration, the mobility and migration experiences of coaches have received limited attention. In this study, we explored the mobility and migration experiences of transnational coaches operating within the Israeli handball context.DesignA qualitative study was conducted, underpinned by our relativist ontology and a constructionist epistemological position.MethodsEight male professionals (e.g., national team coaches, senior team coaches, youth coaches), working (currently, or most recently) in national teams and clubs, who migrated to Israeli handball within the past five years were interviewed. A thematic analysis, integrating inductive and deductive reasoning, was applied in data analysis. Meticulousness was enhanced by focusing on a worthy topic, maintaining credibility, critical friends, producing generalization, and making a significant contribution.ResultsThe analysis yielded raw-data codes, further organized into lower-order themes and three higher-order themes reflecting transnational coaches' migration and mobility experiences within the Israeli handball context, including (a) cultural transition, (b) cultural adaption, and (c) coaches' personal insights about mobility and migration. The findings are conceptually analyzed and discussed in relation to the previous research on coaches' career migration.Discussion and conclusionThe findings emphasize the complexity of the migration process, accompanied by varying motivations, demands and barriers, active decision-making; all within the framework of cultural adaptation. The participants endorsed a transnational coaching career, driven by their open-mind mentality and personal-professional growth.  相似文献

The present study firstly establishes physical education (PE) teachers’ motivational profiles based on their autonomous motivation, controlled motivation and amotivation and, secondly, investigates how different PE teachers’ motivational profiles differ in terms of certain maladaptive antecedents (i.e. psychological need frustration, pressures perceived at work and burnout). It also addresses the differences in their students’ perception of autonomy support, psychological need satisfaction and autonomous motivation. A total of 105 PE teachers and their 2164 students completed validated questionnaires. Four profiles were retained in the cluster analysis. Results showed that teachers who were high on autonomous motivation displayed the most optimal pattern of outcomes, whereas teachers who were high on amotivation showed the opposite pattern. Analysis of the established profiles suggested that the experience of controlled motivation was linked with maladaptive outcomes among both teachers and students. Implications for educational policy and practice are discussed.  相似文献

Using quantitative content analysis, we categorized 76 out of 154 articles (49.35%) published in Adultspan Journal from 1999 to 2019 as focused on gerontological counseling. This study explored publication trends for these articles and compared results with a larger study (Fullen et al., 2019) on publication trends for gerontological counseling across all counseling‐related journals.  相似文献

Lesion–symptom mapping studies have reported a temporal versus frontal dissociation between semantic and letter fluency, and mixed evidence regarding the role of white matter. Mass-univariate and multivariate lesion–symptom mapping was used to identify regions associated with semantic and letter fluency deficits in post-stroke aphasia. Multivariate LSM revealed broad networks including underlying white matter, and substantial overlap between both types of fluency, suggesting that semantic fluency and letter fluency largely rely on the same neural system. All data are available on OSF.  相似文献

In this article it is argued that the attributional literature concerning explanations of poverty is inadequate due to its theoretical presuppositions. It is proposed that a discursive approach is better able to withstand criticism and contribute to a more adequate understanding of poverty accounts. Some examples are given of how a discursive approach might work in practice.  相似文献

The present study examines the perceived causes of date rape by the use of network analysis. The 142 subjects in the study were presented with grids containing 9 causes listed by row and column. They were asked to indicate if they belived there was a causal link between each of the 72 causal pairings. The resulting network placed emphasis on male and female drunkenness, norms of dating, and society's attitude to date rape as distal causes of date rape. Misunderstanding of behavior by men, male attitude that date rape is unimportant, and need by males for dominance were seen as proximal causes. Further networks for each sex were constructed: these showed clear division of opinion on the causes of date rape. © 1995 Wiley-Liss, Inc.  相似文献
