中国近30 年来的农村改革发展历程回顾与展望

文章重点从农村改革的整体性、综合性、协调性和党在农村政策的稳定性、连续性、实效性等方面入手,把我国近30年来的农村改革发展历程划分为三个不同的时期:即从1978年到1988年,是农村改革的起步阶段,出现了第一个“黄金发展期”;从1988年到1998年,是农村改革的停滞阶段,出现了“三农综合症”;从1998年10月至今,是农村改革的快速推进阶段,出现了第二个“黄金发展期”。全面准确地认识和把握我国农村改革的历史进程,对于科学制定农村综合改革的整体方案及相关配套政策措施至关重要。     

微观辨证整体化之浅议

对微观辨证整体化研究 ,认为目前一是应该对大量的前期研究工作进行总结 ,对异病同证者及同病异证者的宏观症状进行循证医学研究 ;对异病同证者及同病异证者的微观指标进行循证医学研究 ;最终寻求宏观整体指标与微观整体指标的结合 ,从而使微观辨证升华到微观层次上的整体化水平。二是进行基因组学与中医证候相关性研究 ,寻找与中医证候相关的基因组 ,从而实现中医证候研究的基因水平上的整体化。     

Application of Markov chain Monte Carlo methods to modelling birth prevalence of Down syndrome

Data collected before the routine application of prenatal screening are of unique value in estimating the natural live-birth prevalence of Down syndrome. However, much of these data are from births from over 20 years ago and they are of uncertain quality. In particular, they are subject to varying degrees of underascertainment. Published approaches have used ad hoc corrections to deal with this problem or have been restricted to data sets in which ascertainment is assumed to be complete. In this paper we adopt a Bayesian approach to modelling ascertainment and live-birth prevalence. We consider three prior specifications concerning ascertainment and compare predicted maternal-age-specific prevalence under these three different prior specifications. The computations are carried out by using Markov chain Monte Carlo methods in which model parameters and missing data are sampled.     

试论美国文化精神的起源与发展

各国历史发展和进程的不同,既有政治、经济的影响,又有文化精神的动因。美国近一百多年来经济的飞速发展和政治进步,得益于它站在巨人肩上的起点,得益于它独特的地理环境和历史条件,更得益于它丰富而充满活力的民族文化精神。美利坚民族文化精神的形成,是有一个历史过程和特殊文化起点的,欧洲大陆的民主传统、清教精神的弘扬、开国者的政治远见、林肯的伟大的解放、进步主义运动之于文化的拯救,都在不同程度上推动和促进了美     

A gender comparison of HIV and drug use across the rural-urban continuum

Despite the central role of women drug users in escalating AIDS statistics, there is still a limited number of studies that examine the roles of gender and drug use type in HIV seroprevalence. This lacuna in the research literature has led to significant gaps in researchers' understanding of how and to what extent women may differ in their drug-using and HIV risk behaviors compared to their better-studied male counterparts. This study, derived from a sample of 3,555 out-of-treatment drug users residing in three South Florida urban and rural communities, attempts to compare the drug usage and needle and sexual risk behaviors of male and female drug users that put them at risk for HIV infection. The overall seropositivity rate for women drug users was 26.5% compared to 19.5% for their male counterparts. Results of multivariate analyses indicate that females compared to males were 1.4 times more likely to be HIV seropositive. Risk behaviors associated with this elevated seropositivity include living arrangements, homeless status, drug use, sexual trading behaviors, and history of STDs. Furthermore, there was a strong linear relationship between drug use type and HIV seroprevalence among women drug users. Compared to those who were neither crack smokers nor injectors of illicit drugs, those who were crack smokers only were 2 times more likely to be HIV seropositive, while those who were both crack smokers and injectors were 5 times more likely to be HIV seropositive, and those who were injectors only were 6 times more likely to be HIV seropositive. These findings indicate that among women, drug abuse and its associated risk behaviors, increase the vulnerability of this population for HIV and thus render them an extremely important priority population on which to focus HIV prevention and public health efforts and programs.     

低龄化写作:填补文学空白的青春抒写

在低龄化写作形成声势与浪潮的今天,回避显然是不智的。从以读者为中心的创作理念这样一个角度去看低龄化写作,我们会对低龄化写作有一个全新的视野。低龄化写作之所以产生巨大声势,就在于我们过去的文学在相当大的程度上忽略了少年成长的心理历程。而低龄化写作对青春的忧伤、疼痛与诗情的表达,弥补了这一空白。至于他们的未来与他们所创造的文学的成熟,我们应该有足够的耐心去等待。     

The case of vegetovascular dystonia: inventing the most common Soviet disease

ABSTRACT

The paper considers the case of vegetovascular dystonia, one of the most typical and common “Soviet” diseases. This syndrome emerged in Soviet medicine after World War II, and very quickly become a popular diagnosis among physicians. The author describes how the construct of vegetovascular dystonia was formed and developed, what changes it underwent, and what affected those changes. The concept and history of vegetovascular dystonia can provide an understanding of Soviet medicine and health science in general.     

Perceptions of paternal involvement and labour pain management in Chinese couples during childbirth: A qualitative study

BackgroundLabour pain is an individual experience embedded in a socio-cultural context. In childbirth, the father’s involvement provides important support to the mother during labour. However, few published studies have evaluated couples’ experiences of paternal involvement and labour pain management in the Chinese context.AimThis study aimed to understand the experience of labour pain management and the father’s involvement in childbirth from the perspectives of women and their partners in Hong Kong.MethodsAn exploratory qualitative design was adopted. A purposive sample of 45 Chinese parents was recruited at the postnatal unit of a regional hospital. Data were collected through semi-structured face-to-face interviews within 1 month after birth. The data were subjected to content analysis.FindingsThe findings revealed six major themes: the mothers’ experience of labour pain, effectiveness of pain relief measures, mothers’ perceptions of support from their partners, mothers’ perceptions of support from healthcare professionals, fathers’ experience of involvement in childbirth and suggested improvements to maternity services.DiscussionChinese mothers experienced intense labour pain and used various pain relief measures. Both parents considered the involvement of fathers and support from healthcare professionals to be highly significant during childbirth.ConclusionsThis study highlights the need for a family-centred model of care during childbirth that involves both parents in the decision-making process. Chinese maternity services should implement individualised birth plans that acknowledge both parents’ expectations and preferences, thus promoting a positive childbirth experience for the parents.     

Parental Alienation: A Measurement Tool

The Rowlands Parental Alienation Scale (RPAS) was administered to 592 parents along with measures of convergent and discriminant validity. The scale was designed to capture the eight domains of parental alienating behavior posited in the literature. Factor analysis extracted only six factors, one of which was not included in the original eight: (a) campaign of denigration towards the alienated parent, (b) the independent thinker phenomenon, (c) reflexive support, (d) presence of borrowed scenarios, (e) spread of animosity to extended family, and (f) lack of positive affect towards the alienated parent. Parents who reported either that a court evaluation or court findings had confirmed the presence of parental alienation scored significantly higher on all six RPAS factors as well as on the overall RPAS score.
