1概述工程技术人员在使用计算机辅助技术进行新产品或新工程的开发和设计时,需要不断地检索、查询和使用标准件、通用件、设计、工艺、工装、设备、仪器、检验等方面的有关信息。因此,建立一个针对CAD标准件的数据库非常重要,因为各种CAD软件都需要有一个标准的零件库进行数据交换。同时随着Internet的发展,将零件库置于互联网上,各CAD用户还可以脱离CAD系统,独立地进行标准件的查询访问、下载使用,为设计开发、销售、采购等提供服务。ISO13584《工业自动化系统与集成零件库》是关于零件库数据的系列国际标准,它提供了…  相似文献

This conceptual article develops a model of how attachment style affects how leaders give feedback and members' react to it. Drawing on attachment theory, we propose that leaders whose trait attachment style is grounded in a desire for security are likely to deliver feedback that is constructive—that is, specific, frequent, timely, behavioral, and future-focused expressed in a way that establishes psychological safety. Leaders who have an anxious attachment style do not want to give members unfavorable feedback that may cause a negative reaction. Leaders who avoid attachment are likely to present little feedback or present unfavorable feedback in a manner that is not constructive—potentially blunt and ego-threatening. Our model also predicts that team members' trait attachment style influences their feedback acceptance mediated by their feelings of psychological safety, with secure attachment style members benefiting most from constructive feedback. Further, we consider how the match (or mismatch) in attachment style between the leader and member influences their reactions to each other as the leader offers feedback and the member reacts. This has implications for assessing the fit between the leader's and team member's attachment styles and designing HR interventions for more constructive feedback and positive reactions.  相似文献

The current study examines the relationship between adult attachment style and both perceived psychological contract breach and affective organizational commitment in a sample of college students with employment experience. Attachment style is argued to be an individual difference factor that affects how an individual perceives organizational events based on theory and existing empirical research related to adult attachment style. Individuals with insecure attachment styles were predicted to perceive more psychological contract breach and have lower levels of affective organizational commitment. The results reveal that individuals with higher levels of preoccupied and dismissive attachment styles perceived higher levels of psychological contract breach, and preoccupied attachment style significantly and negatively relates to affective organizational commitment. The relationship between attachment style and psychological contract dimensions was stronger for relational than transactional contract dimensions. Evidence is also found that perceived psychological contract breach mediates the relationship between preoccupied attachment style and affective commitment. Future potential research directions are described. The implications of these findings for managerial practice is discussed.  相似文献

This study inquires the possible creation of a sense of a place in coffee houses for the disabled people as public places. The physical characteristics of a space are the main factors allowing all people including the disabled ones as well to perceive that place properly and within the “person, place and interaction process” framework. The place attachment, which can be defined as the main emotional bond between space and the users, is heavily influenced by the individualistic experiences and reactions whether they are ordinary or differently abled. In order to initiate a place attachment, spaces should be designed in a way that they respect the occupant’s perception, feelings, memories, senses and their physical abilities to enable them to develop a sense of belonging and ownership. Therefore, creating designs which foster people’s construction process of sense of a place that comprises the concept of identity and sense of belonging, is among the essential issues for realizing place attachment in architecture and design of public spaces. In our contemporary world, there are settings that possess these qualities; contrariwise there are more architectural and urban spaces which ignore these qualities and their benefits for people, especially for the disabled ones. Relatedly, a building should offer people enough information for perceiving it and with its physical features should also support the experiences that occur in it. There is a strong link between memorable events and the space where those events occur. An environment which provides outstanding and meaningful ambiance by its architectural characteristics can establish a sense of a place. Disabled people often have less opportunities to experience the spaces properly compared to others because their limitations are not taken into consideration when designing the public spaces. Therefore, the design process of public spaces should involve the basic needs of disabled people. In order to propose a typology for traditional coffee houses, this research aims to define and discuss the place attachment experience of disabled people in public spaces. The study begins with an overview of identifying different types of disabilities and special needs, and an introductory discussion of how space attachment can help to meet those needs. Therefore, the physical, social and typological aspects of traditional coffee houses were evaluated in terms of location, space organization and functions by considering the profiles of disabled users. Methodologically, this is a case study, which has a mixed research design including qualitative and quantitative research instruments.  相似文献

Prior research has demonstrated that attachment styles are important antecedents of interpersonal relationship quality and psychological well-being. Despite this, the theory of attachment styles has been largely ignored by researchers interested in workplace phenomena. The present paper aims to explain the theory of attachment styles, why researchers have overlooked attachment styles as an antecedent of organizational behavior, and a possible means of reconciling attachment theory with current models of personality. Moreover, I will review what existing research has actually demonstrated in terms of linking attachment styles to leadership, trust, satisfaction, performance and other outcomes. Finally, I will explore what possible future directions may be taken by researchers in the future in order to broaden and deepen our understanding of the role of attachment styles in the workplace.  相似文献

通过室内土柱实验模拟氮素在不同沉积物的潜流带中迁移转化途径,选取粗砂、细砂、粉砂三种介质,以浓度为65.5mg/L的硝酸钾溶液为原水,研究硝态氮在不同沉积物的潜流带中的环境行为;再通过补充碳源,研究碳源对氮的迁移转化过程的影响。实验结果表明,在不同的沉积物介质中,氮的迁移转化不同,主要受介质孔隙度和介质中有机质的制约。由于粉砂介质中孔隙度较小,有利于微生物的附着,且有机质含量较多,反硝化作用和异化还原作用强烈,所以硝酸盐氮下降的最多,而在粗砂介质中孔隙度相对较大,不利于微生物附着,且有机质含量相对较低,反硝化作用和异化还原作用较弱,硝酸盐氮下降的较少。而添加碳源后,反硝化作用和异化还原作用增强,三根柱子中的硝酸盐氮都降到很低的值,说明碳源对潜流带中硝态氮的去除起着重要的作用。  相似文献

In this paper, we draw on attachment theory from the family science literature to develop theoretical propositions that explain variability in one of the most distinguishing features of family firms – its socioemotional wealth (SEW) preservation objectives. Three different attachment styles of founders (avoidant, anxious, secure) are argued to have an imprinting effect on the family firm regarding the relative emphasis that is placed on the preservation of a particular SEW objective (maintenance of control, dynastic perpetuation, reputation) and in turn the HR strategy it chooses to enact (compliance, commitment, collaborative). Avoidant founders are shown to emphasize control as an SEW goal leading them to choose a compliance HR strategy, while anxious founders emphasize dynastic perpetuation that fits well with a commitment HR strategy. Lastly, secure founders are shown to place a priority on reputation, which a collaborative HR strategy helps to reinforce. Contingencies for these relationships are discussed as well as the implications of our model for theory, practice and research.  相似文献
