在指导学生进行钳工技能训练的过程中,我们发现分析产生不合格品的原因成为学生学习过程的薄弱环节。在钳工教材上,不合格品的分析方法只是针对某一项技能训练项目存在质量问题原因进行分析,形式单一,知识局限于某一环节,使学生对产生问题的原因分析把握不准、分析不透、思维狭窄。因此,笔者在钳工技能课上融入了因果分析图方法来分析不合格品的原因,此方法是企业常用分析质量问题原因的方法之一,能从多方面进行综合分析(如人、机、料、法、环)。因为这种方法简单和直观,教师在课堂上教得轻松,学生易掌握,教学效果好。  相似文献

Previous studies have linked the mysterious and inevitable process of aging to essential processes such as metabolism, maturation, and fecundity. Each of these processes is controlled to a large extent by nuclear hormone receptors (NHRs). NHRs also play important roles in the control of periodical processes, the most recently implicated being circadian rhythm. This Review stresses the mounting evidence for tight relationships between each of these NHR-regulated processes and the processes of aging.  相似文献

Using a representative sample from the National Longitudinal Study of Adolescent to Adult Health and a recently developed stepfamily‐process typology, this study explores three plausible functions of perceived neighborhood collective efficacy with respect to stepfamily life and youth adjustment: an ability to (1) prevent maladaptive patterns of stepfamily processes, (2) promote stepchildren's adjustment beyond the influence of stepfamily processes, and (3) protect stepchildren's adjustment when faced with maladaptive patterns of stepfamily processes. The results indicate that higher levels of perceived neighborhood collective efficacy are associated with more adaptive stepfamily processes and higher levels of youth self‐esteem over time, net the influence of stepfamily processes.  相似文献

The cultural change model introduced in this paper covers the cultural change processes and their impacts on housing systems. Cultural processes cause changes in life style learned by the agreed enculturation, acting on the formation of the opinions of the society. Culturation, acculturation, cultural shock, cultural diffusion, transculturation, cultural assimilation are other cultural processes constituting cultural change. The cultural change model for housing proposes that “housing and its close environment physically change in accordance with the cultural processes that are taking place in the related society.” Functions of cultural processes include types of formal or informal housing, urbanization, migration, stratification, life styles, selection of housing equipment, and behavior. Cultural processes have been used as tools to explain the interaction between the above socio-cultural, economic factors and housing patterns of a definite people and place in the cultural change model. A case study was applied in the Sisli–Bomonti region to obtain cultural changes. Cultural processes according to cultural change model were examined in this case study by using the existing results.  相似文献

This paper engages transformation processes by focusing on the racism that characterised pre‐1994 South Africa. Through analysis of an individual life‐history, it argues that individuals engage with contexts of racism in ways that are particular to their intrapersonal and intrapsychic processes. Foregrounding these, the paper argues for the legitimacy of the individual as a site of intervention in transformation processes, and posits that transformation processes that do not account for intrapersonal and intrapsychic dynamics are compromised at best and futile at worst.  相似文献

The current studies examined the importance of domain content in the processes of identity development using two approaches—narrative and status. We examined personal narratives for identity domain content, the co‐occurrence of different contents, and the relations between content and processes, using two approaches to identity—status and narrative. Across two studies, 762 participants (average age = 19 years) and 2214 narratives, traditional ideological and interpersonal status domains were present, but so was a novel domain: existential concerns. Narrative identity processes were more frequent in narratives with multiple contents, and relations between identity statuses processes and narrative processes were modest. We discuss theoretical implications, the importance of examining content, and the utility of narrative approaches for doing so.  相似文献

The journey out of care and towards independent living is a challenge for many care-leavers. There has been little research into the social processes involved in this care-leaving journey. This paper presents the results of a grounded theory investigation into the care-leaving journeys of nine young men who had, several years previously, been in the care of Girls & Boys Town in South Africa. Working from a resilience perspective, with an ecological emphasis, four central social processes emerged that together explain the care-leaving experiences of the participants. These processes are striving for authentic belonging; networking people for goal attainment; contextualised responsiveness and building hopeful and tenacious self-confidence. These four processes are located within contextual boundaries and at the social environmental interface. The paper presents these processes in detail, drawing on selected narratives of the participants and integrated with additional theory. It is hoped that this paper may contribute to theory building concerning care-leaving processes and enhance youth care practices for youth in care and leaving care.  相似文献

This article uses empirical evidence on networks of voluntary organizations mobilizing on ethnic minority, environmental, and social exclusion issues in two British cities, to differentiate between social movement processes and other, cognate collective action dynamics. Social movement processes are identified as the building and reproducing of dense informal networks between a multiplicity of actors, sharing a collective identity, and engaged in social and/or political conflict. They are contrasted to coalitional processes, where alliances to achieve specific goals are not backed by significant identity links, and organizational processes, where collective action takes place mostly in reference to specific organizations rather than broader, looser networks.  相似文献

The paper presents the processes of entrepreneurial human capital accumulation and its impact on rural business growth. Data are derived from four surveys on rural businesses in mountainous and less favoured areas in Southern Europe. Formal pathways of entrepreneurial human capital accumulation refer to education and training, while informal pathways include the cognitive processes of work and managerial experience acquisition and the non-cognitive processes of being raised within an entrepreneurial family environment and/or being raised in the area within which the business is later set-up. The studies reveal that there is a variety of processes of entrepreneurial human capital and knowledge accumulation that are case study specific. Human capital accumulation processes related to education and training or to work and managerial experience still plays the prime role in predicting successful businesses. Results indicate the need for decentralised, flexible and selective entrepreneurial human capital accumulation support programmes that take into account local idiosyncrasies and needs.  相似文献

How might revolutions and other processes of institutional disintegration inform political processes preceding them? By mapping paths of agency through processes of institutional disintegration, the trajectory improvisation model of institutional breakdown overcomes "action-structure" binaries by framing political revolutions as possible outcomes of such disintegrative processes. The trajectory improvisation approach expands the trajectory adjustment model of social change developed by Gil Eyal, Iván Szelényi, and Eleanor Townsley. An overview of political revolution in Soviet Russia between 1989 and 1991 illustrates trajectory improvisation. The recent American invasion and occupation of Iraq shows alternative routes to institutional disintegration, indicating the independence of models of institutional breakdown from those of social movements. These cases illustrate both the diversity of situations the trajectory improvisation model speaks to, and the limitation of models of trajectory adjustment, improvisation, social movements, and invasions, illustrating why such models at best enable what are called "explanatory narratives" of actual historical processes.  相似文献

During the 1990s, the number of regional consultative processes focusing on migration increased significantly. These non‐binding fora brought together representatives of States, civil society and international organizations at the regional level to discuss migration‐related issues in a cooperative manner. Regional consultative processes, which are increasingly supported by governments, are partly a response to the growing complexity and diversity of international migration. Their emergence attests the importance that governments attach to a regional approach to migration management. Regional processes act informally, focusing on cooperative dialogue with an emphasis on information exchange and technical cooperation. The information exchange and confidence‐building that occurs in regional processes is quite important in terms of developing links between States and influencing the likelihood of future bilateral and multilateral agreements. This article focuses upon the development of regional processes, using examples as illustrations. It suggests that the development of regional processes can be understood in terms of a four‐stage model: first, the decision to address issues of concern in a cooperative regional forum; second, to agree upon a “common language”; third, to agree upon a list of goals and, fourth, a shift toward a more operational process.  相似文献
