盖恩斯在《刑前一课》里从零视点与悬念的建构、外视点与悖论的建构、内视点与意识流、多视点聚焦与立体感等方面来研究小说视点与叙事层面的相互关联。他从零视点的角度建构人称悬念、瞬间悬念和期待性悬念,从外视点的角度设置了主题悖论、言辞悖论和语境悖论。为了克服零视点和外视点描述的单调性和乏味性,盖恩斯把内视点与意识流进行了有机结合,从触景生情式意识流、内心独白式意识流和交织式意识流等方面探究人物心理与社会环境的内在关联。他还在人物评述和场景氛围等方面采用了多视点策略,从多层次和多侧面的角度来聚焦于具体的人物、物件或场景,构建了叙事层面的立体感,拓展了现代黑人小说创作的美学认知空间。  相似文献

从藏族古代文化的视角来看,金器太阳神鸟图似乎与斯巴嘎巴和迥瓦风轮的观念有关,斯巴嘎巴和迥瓦风轮观涉及藏族本教的空间时间观和宇宙本体观。斯巴嘎巴是藏语的汉语对音,指空间和时间。迥瓦是藏语的汉语对音,指风火水土四元素。风轮是藏语的汉语意思表达,指“风”为元初原动力的宇宙形成观。在藏语言里,黄金面具实为金面。古藏人非常重视头发及其发型,即便是对死者补妆也是如此,在为死者补妆时,发辫被排在了补妆12点数的首选位置,且头发与绿松石相对应。  相似文献

Problem

Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems.

Background

Due to minimal experience and cultural resistance, few practitioners offer vaginal breech birth, and many practice guidelines and training programmes recommend delivery techniques requiring supine maternal position. Fewer practitioners have skills to support physiological breech birth, involving active maternal movement and choice of birthing position, including upright postures such as kneeling, standing, squatting, or on a birth stool. How professionals learn complex skills contrary to those taught in their local practice settings is unclear.

Question

How do professionals develop competence and expertise in physiological breech birth?

Methods

Nine midwives and five obstetricians with experience facilitating upright physiological breech births participated in semi-structured interviews. Data were analysed iteratively using constructivist grounded theory methods to develop an empirical theory of physiological breech skill acquisition.

Results

Among the participants in this research, the deliberate acquisition of competence in physiological breech birth included stages of affinity with physiological birth, critical awareness, intention, identity and responsibility. Expert practitioners operating across local and national boundaries guided less experienced practitioners.

Discussion

The results depict a specialist learning model which could be formalised in sympathetic training programmes, and evaluated. It may also be relevant to developing competence in other specialist/expert roles and innovative practices.

Conclusion

Deliberate development of local communities of practice may support professionals to acquire elusive breech skills in a sustainable way.  相似文献

British Columbia’s treatment as prevention policy has provided free access to highly active antiretroviral therapy (HAART) to all HIV-positive provincial residents since 1996. One outcome is an increase in HIV-positive gay and bisexual men (GBM) with suppressed viral loads. Previous cross-sectional analyses indicated that some Vancouver GBM now recognize condomless anal sex with men on HAART who report a suppressed viral load as a seroadaptive strategy. To test the hypothesis that this new strategy, termed viral load sorting (VLS), is recognized and used among by GBM in the Momentum Health Study, we analyzed longitudinal data for HIV-negative/unknown (n = 556) and HIV-positive (= 218) serostatus participants. Analyses indicated that both groups reported VLS, and that serostatus and Treatment Optimism Scale scores were significant determinants in frequency and use. Results exemplify the medicalization of sex and Rogers’ Diffusion Of Preventative Innovations Model, and they have important implications for HIV research and GBM sexual decision-making.  相似文献

This study investigates staff and family attitudes towards the use of the fences that surround many aged care facilities in Australia, in the context of indefinite detention of people with dementia. This indefinite detention has been described in a report from an Australian Senate Inquiry as “a significant problem within the aged care context”, which “is often informal, unregulated and unlawful”. Five focus groups comprising direct care workers, family members, nurse unit managers and facility managers discussed the reasons for and their attitudes towards fences. The results show a tension between the provision of physical and emotional safety. This is to say that even while it is illegal to detain people with dementia against their will, and even while participants understood the negative impact of fences on the well‐being and emotional safety of people with dementia, they accepted and supported the presence of perimeter fences because they provided the perception that fences kept people with dementia physically safe. This has implications for redressing the balance between physical and emotional safety in policy and practice.  相似文献

Hybrid organizational forms that combine commercial and welfare institutional logics play an increasingly important role in addressing the grand societal challenges we face today. Building on the literatures on hybrid organizations and social business models, we explore the characteristics of social businesses from a business model perspective. This study seeks to better understand the particularities and value drivers of hybrid social purpose in contrast to purely commercial business models. We follow a grounded theory approach and our findings are based on interview data from 17 social business firms. Building on social businesses' identified particularities, we propose four value drivers of social business models: 1) responsible efficiency, 2) impact complementarities, 3) shared values, and 4) integration novelties. We link our findings to the literature, contributing new insights into social businesses models and implications for practitioners.  相似文献

This article estimates the value of a statistical life (VSL) for Chile under the hedonic wage method while accounting for individual risk preferences. Two alternative measures of risk aversion are used. First, risk aversion is directly measured using survey measures of preferences over hypothetical gambles, and second, over observed individual behaviors that may proxy for risk preferences, such as smoking status, are used. I reconcile the results with a theoretical model of economic behavior that predicts how the wage‐risk tradeoff changes as risk aversion differs across individuals. The VSL estimates range between 0.61 and 8.68 million dollars. The results using smoking behavior as a proxy for risk attitudes are consistent with previous findings. However, directly measuring risk aversion corrects the wage‐risk tradeoff estimation bias in the opposite direction. The results are robust to other observed measures of risk aversion such as drinking behavior and stock investments. Results suggest that, consistent with the literature that connects smoking behavior with labor market outcomes, smoking status could be capturing poor health productivity effect in addition to purely risk preferences.  相似文献

In this article, we attempt to extend and nuance the debate on intellectual property (IP) strategy, appropriation, and open innovation in dynamic and systemic innovation contexts. We present the case of four generations of mobile telecommunications systems (covering the period 1980–2015), and describe and analyze the co-evolution of strategic IP management and innovation ecosystems. Throughout this development, technologies and technological relationships were governed with different and shifting degrees of formality. Simultaneously, firms differentiated technology accessibility across actors and technologies to benefit from openness and appropriation of innovation. Our analysis shows that the discussion of competitiveness and appropriability needs to be expanded from the focal appropriability regime and complementary assets to the larger context of the innovation ecosystem and its cooperative and competitive actor relations, with dispersed complementary and substitute assets and technologies. Consequently, the shaping of complementary and substitute appropriability regimes is central when strategizing in dynamic and systemic innovation contexts. This holds important implications for the management of open innovation, innovation ecosystems, platforms, and coopetition.  相似文献

This paper engages with the ‘mobility turn’ scholarship in order to provide tools for the study of migrants’ integration to urban space. The analysis of urban mobilities draws attention to the practical know-how that underlies mobility practices. I argue that migrants’ urban apprenticeship – that is, the ways migrants learn (to use) city spaces – shape their access to urban resources and their participation in urban life. Based on fieldwork conducted in Lisbon, Portugal, I explore how migrants’ urban knowledges play out in their everyday practices and resonate with broader concerns over migrant integration.  相似文献

《共产党宣言》蕴含着深刻的生态思想,其体系以人、社会、自然整体为背景,其核心观点认为生态问题是由资本主义生产方式引起的.马克思在唯物史观视野下,科学论证了资产阶级的所有制必然灭亡、共产主义必然实现的历史发展逻辑,廓清了人与人、人与自然之间双重和解的演化路径.其中关于科技提升、市场拓展、交通和通信发展等引起世界市场“生态扩张”的思想,对全球化程度日益加深境况下“生态文明”和“人类命运共同体”的构建具有重大的理论和实践指导价值.  相似文献
