A remote-controlled device was developed for injection of fluids and collection of blood samples from freely moving, socially housed animals via an indwelling catheter. Samples are collected at times chosen by the investigator, and the animal is not aware that sampling is occurring. This technique allows measurement of plasma catecholamines and other substances that fluctuate rapidly, are affected by psychosocial stimuli, and are altered by capture and other stressful activities that often accompany sample collection. Rapid retrieval of samples is facilitated by remote-controlled injection of an anesthetic. The device has been used to collect blood from dominant and subordinate male baboons before and during events such as chases and presentation of food treats. Heart rate and blood pressure were measured via radio telemetry, and behavior was recorded on videotapes. This technique allowed construction of multifaceted physiological profiles of social roles and behaviors.  相似文献

In the wake of the 2011 ‘riots’, public order policing tactics in England and Wales have once again been brought into question. Yet, the riots came two years since police regulatory authorities in the UK called for fundamental reforms to the policing of public order. Questions are raised about why the change called for appears to have been so slow and what can be done to assist reform. This paper suggests that developing an evidence‐based policing approach within the field of public order policing to inform police decision‐making would provide the answers. By doing so, the paper addresses some of the possible barriers to implementing evidence‐based policing in public order and calls for police academic partnership to overcome these to make ‘change’ an ongoing reality.

This study investigated the relationship between listener loudness tolerance and listener acceptable noise level (ANL). Twenty-five normal hearing adults completed loudness tolerance and acceptable noise level measures. Loudness tolerance was measured using a scaling technique. The acceptable noise levels were calculated from a procedure designed to quantify a listener's willingness to accept background noise while listening to speech. Pearson correlation confirmed that loudness tolerance and acceptable noise levels are not related.  相似文献

Considering the phenomenology of flow experience reflects attentional processes, Nakamura and Csikszentmihalyi (Handbook of positive psychology, Oxford University Press, New York, 2002) classified the components of flow experience into proximal conditions and the characteristics of a subjective state while being in flow. The present study was conducted to clarify the concept of flow through examination of the interrelationships among the components from a process-related perspective. A total of 1,048 participants completed the Japanese versions of the Flow State Scale-2 (Kawabata et al. in Psychol Sport Exerc 9:465–485, 2008), and based on their scores, 591 respondents were considered to be in a flow state during their physical activity. A proposed higher-order confirmatory factor model and a full structural equation model were tested for the flow respondents. The results of the higher-order model indicated that the 9 flow factors were empirically classified into the flow state and its proximal condition. Furthermore, the outcomes of the full structural model preliminarily supported the hypothesized sequential relationships among flow factors.  相似文献

The impact of community stigmatisation upon service usage has been largely overlooked from a social identity perspective. Specifically, the social identity‐mediated mechanisms by which stigmatisation hinders service use remain unspecified. The present study examines how service providers, community workers and residents recount their experience of the stigmatisation of local community identity and how this shapes residents' uptake of welfare, education and community support services. Twenty individual and group interviews with 10 residents, 16 community workers and six statutory service providers in economically disadvantaged communities in Limerick, Ireland, were thematically analysed. Analysis indicates that statutory service providers endorsed negative stereotypes of disadvantaged areas as separate and anti‐social. The awareness of this perceived division and the experience of ‘stigma consciousness’ was reported by residents and community workers to undermine trust, leading to under‐utilisation of community and government services. We argue that stigmatisation acts as a ‘social curse’ by undermining shared identity between service users and providers and so turning a potentially cooperative intragroup relationship into a fraught intergroup one. We suggest that tackling stigma in order to foster a sense of shared identity is important in creating positive and cooperative service interactions for both service users and providers.

Mental toughness has received increased scholarly attention in recent years, yet conceptual issues related to its (a) dimensionality, (b) nomological network, and (c) traitness remain unresolved. The series of studies reported in this article were designed to examine these three substantive issues across several achievement contexts, including sport, education, military, and the workplace. Five studies were conducted to examine these research aims—Study 1: N = 30; Study 2: calibration sample (n = 418), tertiary students (n = 500), athletes (n = 427), and employees (n = 550); Study 3: N = 497 employees; Study 4: N = 203 tertiary students; Study 5: N = 115 army candidates. Collectively, the results of these studies revealed that mental toughness may be best conceptualized as a unidimensional rather than a multidimensional concept; plays an important role in performance, goal progress, and thriving despite stress; and can vary and have enduring properties across situations and time. This series of studies provides a foundation for further basic and applied research of mental toughness across various achievement contexts.  相似文献
