Federal legislation regarding health care in the U.S. has increased rapidly in the past few years. A major law with potential far-reaching effects was enacted as a result of increasing legislation and rising health care costs. This law,The National Health Planning and Resources Development Act,has created a network of over 200 local, mostly nongovernment units, called health systems agencies. These agencies are responsible for areawide health planning, plan implementation, review and approval of federal health care expenditures for local programs, and facilities review. They will affect health and mental health programs at the local level. The article is directed to local health and mental health care providers who will, of necessity, deal directly with the local HSA's.  相似文献

马克思恩格斯生态思想及创新性发展   总被引:1,自引:0,他引:1  
人化自然作为人的无机身体是人类社会存在的前提,人与自然和谐统一是生态文明的核心;资本主义生产方式造成人与自然、人与人之间新陈代谢关系断裂是资本主义生态危机的主要原因;消灭私有制、建立自由人联合体的共产主义是解决生态危机的最终出路.马克思恩格斯生态思想是当代中国生态文明建设的理论基础和价值准则.以习近平总书记为核心的党中央继承和发展了马克思恩格斯生态思想,提出"生态兴则文明兴,生态衰则文明衰"的生态文明观;"绿水青山就是金山银山"的生态发展观以及"构建人类命运共同体"的生态价值观,是对马克思恩格斯生态思想的创新与发展.  相似文献

“有X没X”是现代汉语框式结构的一种较为典型的语法构式。当前,学界的研究大多是探究“有X没Y”的句法及语用表现,而对于变项“X”属同一形式的现象尚未涉及。通过外层的形式描写和深层的语义分析,鉴别“有X没X”常规和非常规的用法,指出客观叙述性和主观评价性是区别“有X没X”常规和非常规用法的主要方法。同时,利用句法功能的差异,描绘出现代汉语中“有X没X”所有类型的特点,即“有NP没NP”“有VP没VP”“有一Q没一Q”和“有的没的”4类情况的共性及个性。另外,深入诠释转指性和描述性语义特征的不同是“有X没X”常规和非常规用法区别的关键。  相似文献

This study examined associations among family‐level risks, emotional climate, and child adjustment in families experiencing homelessness. Emotional climate, an indirect aspect of emotion socialization, was indexed by parents’ expressed emotion while describing their children. Sociodemographic risk and parent internalizing distress were hypothesized to predict more negativity and less warmth in the emotional climate. Emotional climate was expected to predict observer‐rated child affect and teacher‐reported socioemotional adjustment, mediating effects of risk. Participants were 138 homeless parents (64 percent African‐American) and their four‐ to six‐year‐old children (43.5 percent male). During semi‐structured interviews, parents reported demographic risks and internalizing distress and completed a Five Minute Speech Sample about their child, later rated for warmth and negativity. Children's positive and negative affect were coded from videotapes of structured parent‐child interaction tasks. Socioemotional adjustment (externalizing behavior, peer acceptance, and prosocial behavior) was reported by teachers a few months later. Hypotheses were partially supported. Parent internalizing distress was associated with higher parent negativity, which was linked to more negative affect in children, and parent warmth was associated with children's positive affect. Neither emotional climate nor child affect predicted teacher‐reported externalizing behavior or peer acceptance, but parental negativity and male sex predicted lower prosocial behavior in the classroom. Future research directions and clinical implications are discussed.  相似文献

According to Hannah Arendt, the concept of ‘political action’ is a fundamental component of the human condition because it encapsulates how the uniqueness of each human being intersects to create unpredictable political initiatives and effects. Recently, despite being one of the most daunting political challenges ever faced by humanity, there has been a noted collective action failure, or inaction, concerning the global threat of anthropogenic climate change. Why? This article seeks to explain this political inaction in a new way: by examining the metaphysical role that technology plays in disclosing the climate as a thinkable and global object. After applying the philosophy of Martin Heidegger to the complex mathematical general circulation models (GCMs) used by the Intergovernmental Panel on Climate Change (IPCC), this article details how the metaphysics underlying GCMs manifests the perceivable world by ‘enframing’ it, or by implicitly representing subjects, objects, and Nature itself, as a predictable, calculable, and orderable relation of static forces. When this metaphysical and mathematical uniformity constructs the climate as a calculable object that is globalised through the IPCC, it is ultimately found to be contradictory to the distinctness and unpredictability necessary for distinct human action to occur. Paradoxically, therefore, political action is argued to be metaphysically antithetical to the technologically enframed science, politics, and discourse, of global climate change itself. The importance of distinct and plural human places, when filtered through GCMs, becomes subsumed by the climate as a homogenous, calculative, and politically inactive, global object.  相似文献

科技术语在不同语言之间的翻译是一个复杂的语义匹配过程,如何在考虑相关术语使用现状的基础上将新产生的科技术语准确翻译为其它语言是科技工作者和术语研究者关注的重要问题。以语义场理论为分析框架,通过分析以"水资源管理"及其相关术语为代表的英汉互译,结果发现:不同科技术语在同一语义场所涵盖的语义范围将会随着相关研究深化带来的术语界定细化而发生相应的动态变化;新兴科技术语的翻译要充分考虑其所在语义场其它相关科技术语的翻译先例和使用现状所带来的影响,在翻译准确性和解读便利性之间做出适当的平衡。这是造成"水资源管理"及相关术语英汉互译处理极为复杂的重要原因之一,需要科技翻译者在工作实践中多加注意。  相似文献

ABSTRACT

Adaptation to climate change is emerging as a central objective and policy frame for coastal communities. This paper examines recent climate change adaptation efforts in the UK, centring on the case of Fairbourne, Wales. The village is facing the long-term prospect of flooding and inundation due to the impacts of sea level rise. The recent Shoreline Management Plan for the area has recommended realignment of the coast and eventual decommissioning of Fairbourne. The paper draws on a qualitative research methodology of interviews, policy review and observation to narrate the case and provide key insights and lessons for planners working in environmentally vulnerable coastal settings and managing climate adaptation processes.  相似文献
