IntroductionEven though cycling is an activity whose benefits in terms of urban mobility and health are globally recognized, its disproportional growth during the past few decades has led to some unexpected dynamics. In fact, the increasing number of traffic injuries and deaths involving cyclists has a high cost for public health systems. Considering the available empirical evidence, aberrant and positive behaviors on the road constitute relevant predictors for the injuries suffered by road users. Nevertheless, the scarcity of tools that measure and evaluate the behavior of road users, especially in the case of cyclists, constitutes a serious lack in terms of explaining, intervening and preventing traffic crashes through behavioral approaches.ObjectiveThis study had two essential purposes: first, to describe in detail the validation of measurement of risky and positive road user behaviors of cyclists using the Cycling Behavior Questionnaire. Second, to compare the mean scores of the validated version of the CBQ according to demographic and cycling-related factors.MethodAs a part of a larger collaborative research project, our data was collected from 1064 Spanish-speaking cyclists (between 17 and 80 years old) from 20 countries, who filled out an anonymous electronic survey on their riding behaviors. The data was analyzed using competitive Confirmatory Factor Analyses (CFA), thus obtaining basic psychometric values and an optimized structure for the scale.ResultsThe obtained results suggest that the CBQ has a clear factorial structure, items with high factorial weight, and good internal consistency. In particular, the results of the latent variable model with three factors, which were labeled errors, violations and positive behaviors, show that the CBQ is satisfactorily adjusted.ConclusionThe findings of this research support the idea that the CBQ may have important applications in the improvement of road safety through the study of cyclists' behavioral factors and their relationship to demographic and cycling-related factors.  相似文献

Neuroimaging literature has documented age-related hemispheric asymmetry reduction in frontal regions during task performances. As most studies employed working memory paradigms, it is therefore less clear if this pattern of neural reorganization is constrained by working memory processes or it would also emerge in other cognitive domains which are predominantly lateralized. Using blocked functional magnetic resonance imaging (fMRI), the present study used a homophone judgment task and a line judgment task to investigate age-related differences in functional hemispheric asymmetry in language and visuospatial processing respectively. Young and older adults achieved similar task accuracy although older adults required a significantly longer time. Age-related functional hemispheric asymmetry reduction was found only in dorsal inferior frontal gyrus and was associated with better performance when the homophone condition was contrasted against fixation, and not line condition. Our data thus highlights the importance of considering regional heterogeneity of aging effects together with general age-related cognitive processes.  相似文献

Video summarization is one of the key techniques to access and manage a huge chunk of videos. Video summarization is used to extract the effective contents of a video sequence to generate a concise representation of its content. The involvement of crowdsourcing models in recent years is effectively used by researchers in E-commerce domain to increase the quality of the data contents. In this paper, we present a video summarization framework based on users emotion while they watch videos by analyzing cerebral activities through Electroencephalogram (EEG) signals. Three emotions, namely happy, sad and neutral have been extracted from the EEG signals. Video frames have been synchronized with EEG signals and tagged with various emotions. Finally, a crowdsourcing model has been used for effective summarization of the videos. The qualitative assessment of video summarization has been conducted with the help of user ratings using online Google Forms application. EEG signals of 28 users have been recorded while video streams of different emotions. An average accuracy of 83.93% has been recorded in emotion classification using crowdsourcing. Output summarized videos include dynamic video skims and the corresponding audio stream for better understanding.  相似文献

Following a period of decline beginning in the early eighteenth century, the Orthodox Church in Russia held a general council in Moscow from August 1917 to September 1918. More than 500 clergy and laity met, prayed and discussed numerous issues relating to the church’s life and witness. The Moscow Council was prompted by various trends of renewal which were growing ever stronger among the clergy and laity. Political circumstances at the time also made the Council possible: a preparatory preconciliar process was initiated in 1905, in parallel with the first revolution against Emperor Nicholas II, and the Council itself was convened in 1917, in parallel with the establishment of a Provisional Government. However, it was precisely such political events which led to the premature interruption of the Council. The main items on the Council’s agenda were linked to the reformation of church structures and the implementation of conciliar provisions at every level of church life: parish, deanery, diocese and autocephalous church. Special attention was given to the renewal of the pastoral ministries of priests and bishops, and to that of committed laity. In a way, the Moscow Council was a kind of ‘first encounter’ of Orthodoxy with contemporary societies, secularised or on the road to secularisation. Its legacy is therefore of great interest to all Christianity today. This article aims to analyse the Council and the main decisions made, in the light of ecclesiology, and to provide a primary bibliography at the end of the text.  相似文献

This study reexamined the organization of Young’s 18 early maladaptive schemas and their hypothesized associations with experiences of need-thwarting parental experiences in childhood and the “vulnerable child” mode of emotional distress in adulthood. A large Danish sample (N = 1054) of 658 clinical- and 391 nonclinical adults completed measures of early maladaptive schemas, parenting styles, and the vulnerable child mode. We identified four higher-order schema domains as most appropriate in terms of interpretability and empirical indices (“Disconnection & Rejection”, “Impaired Autonomy & Performance”, “Excessive Responsibility & Standards”, and “Impaired Limits”). All four schema domains were differentially associated with conceptually relevant need-thwarting parental experiences. Apart from “Impaired Limits”, the schema domains meaningfully accounted for the association between need-thwarting parental experiences in childhood and emotional states of feeling like a “vulnerable child” in adulthood. We conclude that four domains of early maladaptive schemas are empirically and conceptually consistent with Young’s schema therapy model of personality pathology and longstanding emotional disorders. Findings warrant replication using different populations and if possible a prospective multi-method design. A scoring key for computing the four schema domains is provided.  相似文献

The authors examined whether a newly developed group therapy, based on principles of attachment theory and emotionally focused couples therapy, can potentially address the unique mental health and relationship difficulties in caregivers of individuals with Parkinson's disease. A comprehensive outreach effort, involving a review of 251 military veterans' medical records, yielded enrollment of seven spousal caregivers in the group therapy. At 1-month follow-up, caregivers who initially reported mild or greater levels of caregiver burden demonstrated statistically reliable declines in psychological distress, relationship distress, or both. Posttreatment surveys indicated positive perceptions in overall helpfulness of treatment goals, as well as positive changes in insight (e.g., greater understanding of the patient's attachment needs) and behaviors (e.g., greater social contact and self-care of the caregiver). Results are considered in the context of inadequate access to treatment for caregivers of spouses with Parkinson's disease or other major medical issues.  相似文献

ABSTRACT

Exposure to natural disasters can lead to both negative and positive mental health consequences (i.e., posttraumatic stress disorder [PTSD] and posttraumatic growth [PTG]). While there is evidence linking metacognition to these outcomes, the focus is mostly on maladaptive metacognitions. The present study investigated the role of positive metacognitions and meta-emotions (i.e., confidence in extinguishing perseveration [Extinguishing], confidence in interpreting emotions as cues [Interpreting], and confidence in setting flexible and attainable hierarchies of goals [Setting]) on PTSD and PTG among Filipino typhoon survivors. Findings supported a model wherein Extinguishing and Setting, but not Interpreting, predicted PTSD and PTG through posttraumatic cognitions.  相似文献

The State-Trait Anxiety Inventory for Children is a self-report instrument inspired on the State-Trait theory extended by Spielberger that measures a momentary state of anxiety (state) and a stable tendency to experience anxiety (trait). This study presents an exploratory adaptation of the Trait Scale and provides its psychometric properties for European Portuguese children and adolescents. The influence of sex and age were also explored. Our sample, composed of 402 participants aged 8–14 years, revealed a mean anxiety value of 28.37 (SD = 5.99). As expected, females revealed higher levels of anxiety than boys. Higher anxiety was obtained in our youngest group as compared to the oldest group. The exploratory factor analysis led to retaining only 16-items that presented acceptable adjustment to a one-factorial solution. Good indexes were obtained in the confirmatory analysis. The results also revealed good internal consistency and good test-retest reliability. Our results provide initial evidence that this scale is adequate to measure trait-anxiety in European Portuguese young people.  相似文献
