近三十年来,中国经济实现了持续高速增长,但增长动力结构失衡。在投资、消费、净出口三大需求对国民经济发展的拉动中,消费率偏低是一个不争的事实。消费率,即消费需求在支出法国内生产总值中所占的比重,反映的是从长期考察的一个国家在其发展过程中所处的历史阶段,而不是短期内国家宏观和微观的经济运行情况。它的高低适中不能用宏观和微观经济运行情况来判定,而是要看其是否与国家或地方的经济发展方式和路径相适应。中国经济发展正处于消费率由低转高的历史阶段,中国消费率的上升是一个渐进的过程,需要从宏观上实现一系列的国民收入分配机理运行工程,即劳动收入的国家干预工程、要素收入的二次分配工程、扩大公共消费工程和加大财政转移支付工程。  相似文献

每一种组织,由于自身特殊的环境条件,都会形成由自我意识所构成的精神文化体系。对资源委员会来讲,这一文化体系集中体现在三个方面:首先,在对国营事业的理解方面,他们坚信发达国家资本,发展国营事业是中国工业化的必由之路。其次,通过多种形式的宣传灌输,塑造“公、诚、拼”的国营事业精神,不断强化组织成员对自己事业的认同和对事业应有精神和文化的体认,从而彰显出这一组织价值观念的独特个性。再次,资委会的技术官僚,不同于其它政府官员,他们的目标在于借行政舞台,圆富国强国的梦想。他们虽跻身官僚之列,但却不是以“官”的职能在那里活动,而是以企业者、专家或技术人员的身份在那里活动。因此,他们忠诚于民族国家而不是政府长官或某一阶级政党。正是这些精神文化因素使资委会与国民政府其它行政机构区别开来,并成为国民政府执政时期的一个亮点。  相似文献

由于50年代中后期国际形势变化和日本实力的迅速增长,美国被迫重新考虑对日战略问题。在新美日安全条约签订后,美国统治集团的经过充分讨论估价,终于通过于国家安全委员会6008/1号文件,这一文件的基本原则成为此后美国对日政策的核心。  相似文献

中共六大在探索苏维埃政权建设的过程中,更加注重工农群众主体地位的巩固和能动作用的发挥,较为系统地论述了政权建设中的群众思想。其着重从四个方面加以阐述,形成了以实现好、维护好和发展好最广大人民群众的根本利益为政权建设的根本出发点和落脚点;尊重和激发人民群众的主体创造潜能为推动政权建设的内生动力;解决好人民群众最直接、最现实、最关心的民生问题为政权建设的着力点;始终坚持群众思想、践行群众路线为政权建设的根本路线方针等为主体内容的群众思想,对当代政权建设中的群众路线实践具有重要的理论价值和现实意义。  相似文献

近年来,随着经济的发展和人们思想的解放,越来越多体现和平年代军队建设与军人生活的电视剧出现在荧屏上,一大批阳刚、稳重、坚韧、刚毅的军人形象受到观众喜爱。和平年代,军旅剧中的军人形象发生了许多变化,如人物身份地位普通化、性格塑造丰富化、人物生存状态真实化,这些变化更加彰显了当代军人的真实风采。然而,在军旅剧人物走向大众的同时,也呈现出人物新模式化、人物设置偏颇以及娱乐元素滥用等新问题,阻碍了军旅剧的进一步向前发展。文章结合作品对当代军旅剧中军人形象的变迁以及出现的问题进行分析,以期为后来的军旅剧创作有所启示。  相似文献

The purpose of the current study was to examine the relationships among discrimination, mental health, and body image in a national sample of transgender adults. Participants (N = 78) identified as transgender, genderqueer, or other gender-non-binary identities and were recruited via a national online survey. Harassment/rejection, work/school, and other discrimination explained 10.4% of the variance in body appreciation, while satisfaction with life, anxiety, self-esteem, and depression explained 60.7%. Within these models, harassment/rejection was inversely associated with body appreciation, while self-esteem and satisfaction with life were positively associated. A series of path models moving from a measurement model to a more parsimonious and excellent-fitting model found that the effect of harassment/rejection on body appreciation was fully mediated by self-esteem and satisfaction with life, resulting in a multiple mediation.  相似文献

High-content automated imaging platforms allow the multiplexing of several targets simultaneously to generate multi-parametric single-cell data sets over extended periods of time. Typically, standard simple measures such as mean value of all cells at every time point are calculated to summarize the temporal process, resulting in loss of time dynamics of the single cells. Multiple experiments are performed but observation time points are not necessarily identical, leading to difficulties when integrating summary measures from different experiments. We used functional data analysis to analyze continuous curve data, where the temporal process of a response variable for each single cell can be described using a smooth curve. This allows analyses to be performed on continuous functions, rather than on original discrete data points. Functional regression models were applied to determine common temporal characteristics of a set of single cell curves and random effects were employed in the models to explain variation between experiments. The aim of the multiplexing approach is to simultaneously analyze the effect of a large number of compounds in comparison to control to discriminate between their mode of action. Functional principal component analysis based on T-statistic curves for pairwise comparison to control was used to study time-dependent compound effects.  相似文献

The present study explored how women aged 50–65 years reflect and make meaning of a lifetime of body and weight struggles. Seven purposefully selected women with longstanding body image challenges participated in interviews and reflected on their perceptions, thoughts, and emotions around their body and weight since childhood. Findings revealed consistent and consuming concerns about the body; prevalent body-related self-conscious emotions; influential social experiences that impact physical self-perceptions; and enduring impacts of weight bias, stigma, and discrimination. Collectively, these findings provide support for the stability of body disturbances and highlight the need to explore the unique body-related narratives of women in midlife.  相似文献

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Objectives

The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).

Methods

After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.

Results

The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).

Conclusion

Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed.  相似文献
