Abundant research conducted in Western contexts has shown that biological risk factors such as low resting heart rate (HR) might be related to childhood aggression. However, it was unclear (1) how resting HR, as well as other markers of cardiac functions such as resting vagal tone, may be related to subtypes of aggression such as reactive and proactive aggression, and (2) whether the HR-aggression relation can be replicated in non-Western contexts. Therefore, this study examined the concurrent and prospective relations between resting HR, vagal tone, and Chinese children’s reactive and proactive aggression. Participants were 183 children (M age?=?7.64 years, 91 girls) recruited from an elementary school in Zhenjiang, PRC. Children’s resting HR and vagal tone were assessed in the second grade (T1). Teachers rated children’s reactive and proactive aggression in the second (T1) and fourth grade (T2). Results showed that lower resting HR at T1 was associated with higher reactive and proactive aggression at T1 and T2, and higher vagal tone was associated with lower HR, which in turn was related to higher reactive and proactive aggression at T1 and T2. Lower vagal tone was directly related to higher reactive but not proactive aggression at T1 and T2, whereas lower HR was related to higher reactive aggression at T2 for children with low or moderate vagal tone but was not for children with high vagal tone. These psychophysiological findings from a non-Western context add additional support for both similarities and differences between reactive and proactive aggression in childhood.  相似文献

自身免疫性胰腺炎(AIP)是一种特殊类型的慢性胰腺炎,以胰腺肿大及胰管不规则狭窄为特征.AIP分两个亚型:Ⅰ型AIP好发于亚洲老年人,为淋巴浆细胞硬化性胰腺炎;Ⅱ型AIP多见于西方人,为导管中心型胰腺炎.AIP缺乏特异性血清标志物,诊断主要依赖于其特征性改变.依据AIP诊断标准国际共识,AIP的诊断包括影像学、血清学、胰腺外器官受累、组织病理学和诊断性激素治疗5个方面.糖皮质激素是AIP的首选治疗方法,但复发率高,免疫调节剂对维持AIP的持续缓解具有一定作用.AIP总体预后良好,胰管结石和癌变是其潜在的并发症,但发生率极低.  相似文献

直肠间质瘤致下消化道大出血1例报告   总被引:1,自引:0,他引:1  
胃肠道间质瘤是一种发生于消化道的少见的间叶肿瘤,直肠间质瘤更为罕见,在直肠肿瘤中的发生率0.1%以下。直肠问质瘤的临床表现无特异性,与其他直肠肿瘤相似,随肿瘤逐渐增大可表现为排便习惯改变、便血、排便困难等。临床确定诊断困难。手术治疗是能够治愈直肠问质瘤的唯一方法。格列卫作为一线化疗药物对术前降期及改善预后都有良好疗效。本例患者因下消化道大出血入院,肿瘤近肛缘,术中病理考虑为直肠闻质瘤,完整切除肿瘤后行保肛术。术后应用格列卫,随诊3个月无复发、转移。  相似文献

The paper explores the role of body in Epictetus’s Discourse and Buddhist Satipa??hāna Sutta and underscores the importance of embodied practice in Epictetan askēsis (‘training or exercise’). It argues that the important but unrecognized role of the body in Epictetan askēsis can be better understood if we introduce in some perspectives of early Buddhism. From the angle of spiritual exercise, early Buddhism maintains that the meditator ought to experience the body directly and contemplate the body as an impermanent physical object, and not identify oneself with it. And based on the insight into the reality of the body and the cultivation of bodily awareness, the meditator can detach himself from the transient phenomenon and remove the unwholesome states of mind. Similarly, for Epictetus, by training our impression on the body and regarding the body as an indifferent thing but not the true self, one may successfully attain the truth of the body conditioned in various social contexts and then realize detachment and freedom. Therefore, in both early Buddhist meditation and Epictetan askēsis, the embodied practice of contemplating the body as it actually is, is also a spiritual exercise to understand the phenomenal world and detach from external things and to examine and tranquilize the internal world.  相似文献

Inter-organizational collaboration (IOC) research considers the achievement of a collaborative identity as a key enabler of a successful collaboration. As a result, little has been said about the interactions between collaborative and non-collaborative identities. We build on narrative identity work and positioning theory, to explore how collaboration partners engage in identity work positioning to manage the interactions of the multiple identities emerging through the process of collaboration as they try to accomplish collaborative work. We illustrate this process through a qualitative longitudinal study of an educational partnership in Greece. Our analysis shows how IOC partners manage the interactions between collaborative and non-collaborative identities by positioning themselves, and others, in narratives of collaboration as part of their daily identity work when responding to emerging collaborative needs. Our research extends our current understanding of identity work processes in IOCs by demonstrating the paradoxical nature of the collaboration, which requires relying on both collaborative and non-collaborative identities for the successful achievement of aims. We therefore suggest that identity tensions should not be resolved but rather managed, since they enable partners to respond creatively to contextual organizational changes and make sense of the collaboration as it happens.  相似文献

Presentation of two kinds of materials in working memory (visual and acoustic), with the requirement to attend to one or both modalities, poses an interesting case for working memory development because competing predictions can be formulated. In two experiments, we assessed such predictions with children 7–13 years old and adults. With development, the ability to hold more information in the focus of attention could lead to an increase in the size of the trade‐off between modalities; if attention can hold A items during unimodal‐attention trials, then on average attention should hold A/2 of those same items during bimodal‐attention trials. If A increases with age, so would the dual‐task cost, A/2. The results clearly ruled out that possibility. It was the modality‐ or code‐specific components of working memory that improved with age and not the central component. We discuss various mechanisms that could have produced these results, including alternative attention‐based mechanisms. The findings point to a rich field for continued research.  相似文献

The visual system is remarkably efficient at extracting regularities from the environment through statistical learning. While such extraction has extensive consequences on cognition, it is unclear how statistical learning shapes the representations of the individual objects that comprise the regularities. Here we examine how statistical learning alters object representations. In three experiments, participants were exposed to either random arrays containing objects in a random order, or structured arrays containing object pairs where two objects appeared next to each other in fixed spatial or temporal configurations. After exposure, one object in each pair was briefly presented and participants judged the location or the orientation of the object without seeing the other object in the pair. We found that when an object reliably appeared next to another object in space, it was judged as being closer to the other object in space even though the other object was never presented (Experiments 1 and 2). Likewise, when an object reliably preceded another object in time, its orientation was biased toward the orientation of the other object even though the other object was never presented (Experiment 3). These results demonstrated that statistical learning fundamentally shapes how individual objects are represented in visual memory, by biasing the representation of one object toward its co-occurring partner. Importantly, participants in all experiments were not explicitly aware of the regularities. Thus, the bias in object representations was implicit. The current study reveals a novel impact of statistical learning on object representation: spatially co-occurring objects are represented as being closer in space, and temporally co-occurring objects are represented as having more similar features.  相似文献

Although the value of relational benefits has been recognised in customer relationship management, the impact of these benefits on loyalty behaviours is yet to be investigated in the context of loyalty clubs. Little is known why some loyalty programmes outperform others. By using both qualitative and quantitative research approaches, this research developed and estimated a conceptual model that describes the interaction of key relational benefits and their contributions to customer loyalty in a set of milk formula customer clubs in China. Data were collected from 300 Chinese infant milk formula buyers, including both customer club members and nonmembers. This study confirms that the customer‐confidence benefits and identity‐related benefits precede other loyalty rewards and strengthen other loyalty incentives in a loyalty programme. The economic benefits and information‐sharing benefits play a mediating role and contribute directly to customer loyalty. The findings of this research help better understand the mechanism behind loyalty behaviours in customer clubs.  相似文献
