天津临港工业区雨水规划特点

一、天津临港工业区概况 天津临港工业区位于海河人海口南岸地区,大沽沙河道南侧,北部为天津港南疆港区,西北部为塘沽东大沽生活区,西部为天津港南疆散货物流中心,南部为规划海滨风景旅游区。临港工业区原状为滩涂,滩面宽广,地势平缓,标高较高,为-2．5米-4米（理论基准面高程）,围海造地条件良好,远期标高将深入至约-4米。     

A permutation test approach to the choice of size k for the nearest neighbors classifier

The k nearest neighbors (k-NN) classifier is one of the most popular methods for statistical pattern recognition and machine learning. In practice, the size k, the number of neighbors used for classification, is usually arbitrarily set to one or some other small numbers, or based on the cross-validation procedure. In this study, we propose a novel alternative approach to decide the size k. Based on a k-NN-based multivariate multi-sample test, we assign each k a permutation test based Z-score. The number of NN is set to the k with the highest Z-score. This approach is computationally efficient since we have derived the formulas for the mean and variance of the test statistic under permutation distribution for multiple sample groups. Several simulation and real-world data sets are analyzed to investigate the performance of our approach. The usefulness of our approach is demonstrated through the evaluation of prediction accuracies using Z-score as a criterion to select the size k. We also compare our approach to the widely used cross-validation approaches. The results show that the size k selected by our approach yields high prediction accuracies when informative features are used for classification, whereas the cross-validation approach may fail in some cases.     

Gambling and problem/pathological gambling among ex-offenders in Hong Kong

This paper considers the issue of ex-offenders who can be identified as having an addiction to gambling; one that has been long-neglected in Hong Kong. It reports on a study in which 378 ex-offenders were asked to assess their gambling involvement. The paper identifies the importance of social workers developing a better understanding of this issue in their work with ex-offenders and the findings suggest there is further scope for research and analysis about the extent of this problem and its management.

The Contribution of Job and Partner Satisfaction to the Homeostatic Defense of Subjective Wellbeing

Two studies investigate subjective wellbeing (SWB) homeostasis. The first investigates the contribution of job satisfaction (JS) and partner satisfaction (PS) to the homeostatic defense of SWB. The extant model of homeostasis does not include either variable. The second study investigates the relationship between Homeostatically Protected Mood (HPMood) and other factors involved in the homeostatic model. It has been proposed that HPMood is the basic, biologically determined, positive mood that saturates SWB and other related variables, and forms the basis of the SWB set-point. Thus, if HPMood is an individual difference and it perfuses other homeostatic variables, then HPMood should be responsible for much of the shared variance between such variables. Two comparative samples are involved. One is a group of 171 Hong Kong Chinese recruited through convenience sampling. The other is a group of 343 Australians recruited via a general population survey. Results indicate that both JS and PS predict significant variance in Global Life Satisfaction beyond the existing factors in the homeostatic model. It is also found that, after controlling for the effect of HPMood, the strength of correlations between SWB and other homeostatic variables is significantly diminished. The implications of these findings are discussed.     

我国出生人口素质偏低对发展的影响及其对策建议

中国是世界第一人口大国,也是出生缺陷高发国家。在庞大的人口数量压力还未减轻的同时,又面临着出生人口素质偏低的客观现实,严重制约了我国整体人口素质的提高。本文分析了我国出生人口素质偏低的原因,重点探讨了出生人口素质偏低对社会经济、家庭和个体发展的影响,在其基础上提出了有针对性的对策措施。     

Single-machine scheduling with general sum-of-processing-time-based and position-based learning effects

In this paper, we propose a new learning effect model in which the actual job processing time is a general function of the normal processing time of jobs already processed and its scheduled position. This model has the advantage that different learning curves can be constructed easily, such as the plateau function. It is found that most of the models in the literature are special cases of our proposed model. The optimal sequences for some single-machine problems are then provided.     

论我国家事纠纷人民调解的新机制——以澳大利亚"家庭关系中心"之家事纠纷调解为视角

目前,我国人民调解制度在家事纠纷调解方面的不足包括:立法不完善;专门机构缺失;专业人员缺位以及调解机制不健全等.澳大利亚"家庭关系中心"之家事纠纷调解的经验值得借鉴.建议我国增补专门的立法、设立专门的"家事纠纷调解中心",实现调解人员专业化、职业化,并规定对所有婚姻家庭案件除婚姻无效案件等不能调解外,人民法院均应指定当事人须到"家事纠纷调解中心"进行咨询、调解.应确认人民调解协议的法律效力,且建立多机构联合调解家事纠纷的社会调解网络,构建家事纠纷的人民调解新机制,以及时、妥善地解决家事纠纷,减少诉讼,促进我国平安家庭与和谐社会的构建.

Experimental Coastal Land Reclamation: Qianhai as a Case Interpreted

ABSTRACT

Informed by a Coasian transaction cost paradigm enriched by the concept of Schumpeterian innovations, this paper discusses the advantages of using experimental coastal reclamation of the sea to build new cities with a policy for fostering innovations. A new development area at the margin of Shenzhen in China, Qianhai, is used to demonstrate how urban expansion by urban sprawling in a megacity can be avoided by reclamation of marginal land as analytically less costly than along intra-marginal land and more suitable for experimentation for the type of megacity concept that Qianhai aims to achieve.
