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.     

现代汉语框式结构“有X没X”的构式分析

“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。     

Increased prevalence of premature ejaculation in men with metabolic syndrome

This prospective study aimed to investigate the relationship between metabolic syndrome (Met S) and premature ejaculation (PE) among men. The study included 300 consecutive male patients (53.6 y?±?8.7) who attended the urology clinic (December 2013–September 2014), mostly complaining of renal/ureteric calculi. A diagnostic approach was undertaken to include demographics, clinical features and laboratory investigations of the study subjects. Both erectile function and PE were evaluated using the International Index of Erectile Function (abridged form, IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires, respectively. Results identified 182 (60.7%) men had Met S. Prevalence of PE was significantly higher in the subjects with Met S than the controls (35.2% vs 7.6%, p?< 0.001). Patients with Met S and PE had significantly higher PEDT scores (15.4 vs 6.7), smaller waist circumference (108.3?cm vs 111.5?cm) and higher fasting blood sugar (187?mg% vs 161?mg%) than those with no PE (p?p?=?0.047 and <0.001, respectively) with PE in Met S. In conclusion, PE has a high prevalence in Met S. Patients with Met S should be questioned about PE. Both ED and systolic hypertension may be associated with PE. Prevention of Met S should be considered, and this may be of help to decrease the prevalence of PE.     

Robustness to non-normality and autocorrelation of individuals control charts

This paper studies the effects of non-normality and autocorrelation on the performances of various individuals control charts for monitoring the process mean and/or variance. The traditional Shewhart X chart and moving range (MR) chart are investigated as well as several types of exponentially weighted moving average (EWMA) charts and combinations of control charts involving these EWMA charts. It is shown that the combination of the X and MR charts will not detect small and moderate parameter shifts as fast as combinations involving the EWMA charts, and that the performana of the X and MR charts is very sensitive to the normality assumption. It is also shown that certain combinations of EWMA charts can be designed to be robust to non-normality and very effective at detecting small and moderate shifts in the process mean and/or variance. Although autocorrelation can have a significant effect on the in-control performances of these combinations of EWMA charts, their relative out-of-control performances under independence are generally maintained for low to moderate levels of autocorrelation.     

Likelihood estimation for a general class of inverse exponentiated distributions based on complete and progressively censored data

In this paper, we establish the existence and uniqueness of the maximum-likelihood estimates of the parameters of a general class of inverse exponentiated distributions based on complete as well as progressively Type-I and Type-II censored data.     

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.     

互动视角下构式压制和承继的合力机制——基于羡余否定构式“好不X”封闭语料库的研究

构式与其组构成分间的互动关系一直是构式语法关注的核心问题之一。Goldberg在构式语法理论框架中提出了动词与构式的双向互动观，但在实际论述中却过于强调构式对动词的单向压制，降低了动词义对构式生成的贡献，忽略了对构式组构成分的系统研究。以构式与其组构成分间的互动关系为视点，从构式压制与承继的辩证关系出发，进一步阐释图示构式生成是构式与组构成分在互动压制和多重承继合力作用下的结果。同时，基于封闭语料库穷尽分析汉语羡余否定构式"好不X"的特征，结果表明：构式压制与词汇压制是双向互动的；图示构式特征的形成取决于构式对其组构成分的多重动态承继；图示构式基于互动压制承继合力机制的形成。     

Generation Xers’ performance and development in midlife transition

Midlife transition is an inevitable process that every adult faces during his or her life. As Generation Xers move into middle age, the field of human resource development (HRD) should keep pace with the impact of this midlife transition on this cohort’s psychological and physical welfare and continuous development. An effective way to cope with midlife transition is to face it as an opportunity for change and self-actualization. Gender as well as physical and psychological changes are important factors in midlife transition. Organizations should understand the challenges of midlife transition and create a supportive environment for Generation Xers to cope with the changes. Specific suggestions for middle-aged Generation Xers and HRD professionals are provided in this article, as well as implications and recommendations.
