建设工程质量竣工备案评价机制探讨

建设工程质量竣工备案评价是政府质量监督机构对建设工程项目质量能力和水平的全过程的总体把握,本文根据对建设工程质量竣工备案进行产品质量、物质质量和监督过程质量进行综合评价所形成的指标体系,提出了实现有效评价的模糊综合评价的方法与过程,阐述了竣工备案综合评价的三个基本功能:反映功能、监测预测功能和比较功能,分析了评价的五个特点:具体性、模糊量化性、解释说明性、时间性、综合性,构架了有效评价的组织与运行机制,对于提高政府质量监督竣工备案决策的科学性具有理论指导意义。     

Can We Use Human Judgments to Determine the Discount Rate?

It has been suggested that the long-term discount rate for environmental goods should decrease at longer delays. One justification for this suggestion is that human judgments support it. This article presents an experiment showing that judgments concerning discount rates are internally inconsistent. These results point to potential problems with the use of judgments referenda for determining discount rates in cost-benefit analyses.     

Correlation between the Japanese Aging Male Questionnaire (JAMQ) and Aging Male’s Symptom (AMS) scale in Japanese male

Abstract

Objectives: To clarify the correlation between the Japanese Aging Male Questionnaire (JAMQ) and the Aging Males’ Symptoms (AMS) scale through the factor analysis in Japanese male.

Materials and methods: In 61 male patients who visited the LOH outpatient clinic of Teikyo University Hospital, subjective symptoms featuring LOH were evaluated using the JAMQ and AMS. Factor analysis was performed on each questionnaire to clarify the LOH-related factors. Correlational analysis between the subscale scores representing such factors and the serum hormone profiles was also performed.

Results: Factor analysis of the JAMQ revealed an internal structure consisting of three subgroups: somatic, psychological and sexual factors with good categorization of the indicators to the appropriate subgroup. In contrast, the indicators of the AMS showed incomplete conformity to the subgroups of the JAMQ. Correlational analysis showed that each score on the JAMQ subgroups had the highest coefficient of correlation with the corresponding AMS subgroup (p?<?0.001). There was no significant association between total and free serum testosterone levels and the total and subscale scores on either AMS or JAMQ.

Conclusions: The results of factor analysis suggest that the sexual perceptions of Japanese populations might differ from those of Caucasian populations. JAMQ would be useful to separately assess individual aspects of somatic, psychological and sexual symptoms related to LOH among Japanese males.     

网上小额批发商言语性评价的维度分析

随着网上小额批发平台的快速发展及其对信誉评价体系不断完善的要求,以文字内容为主的言语性评价受到广泛关注。基于内容分析法对阿里巴巴速卖通平台的言语性评价的编译,细化出九大类、29项维度,分别涉及交易过程、质量、定价、服务、物流、卖家信用、主观感受、未来行为倾向等内容。网上批发商混合采用主客观评价相结合、整体和细节评价相结合的方式,且在商品质量、交易经历、整体服务水平、整体物流水平及对商品的喜好程度等维度上表现出明显的正负向情感。通过进一步的潜在类别分析,发现网上小额批发商分为＂关注质量的主客观评价型＂和＂整体综合评价型＂,进而提出解释和建议。     

Optimal Threshold from ROC and CAP Curves

Receiver Operating Characteristic (ROC) and Cumulative Accuracy Profile (CAP) curves are used to assess the discriminatory power of different credit-rating approaches. The thresholds of optimal classification accuracy on an ROC curve and of maximal profit on a CAP curve can be found by using iso-performance tangent lines, which are based on the standard notion of accuracy. In this article, we propose another accuracy measure called the true rate. Using this rate, one can obtain alternative optimal thresholds on both ROC and CAP curves. For most real populations of borrowers, the number of the defaults is much less than that of the non defaults, and in such cases using the true rate may be more efficient than using the accuracy rate in terms of cost functions. Moreover, it is shown that both alternative optimal thresholds by using the true rate are the identical, and this single threshold coincides with the score corresponding to Kolmogorov–Smirnov statistic used to test the homogeneous distribution functions of the defaults and non defaults, whereas the optimal threshold by using the accuracy does not the same as the score corresponding to Kolmogorov–Smirnov statistic. These facts are explored with some simulation and illustrative examples.     

收视率与电视艺术审美的哲学思考

收视率作为媒介产业化的必然产物,代表的是拥有巨大力量的市场法则,是电视媒体运作管理和节目考评的核心指标。电视艺术审美作为电视艺术的"质"和"魂",是塑造电视节目品质的关键。通过探讨电视艺术审美与收视率的矛盾交互关系,一方面希望促进电视产业的发展,为电视艺术提供必要物质支持和广阔发展空间;另一方面希望通过净化电视文化生态环境,正确地引导和提升观众的审美文化素养,以实现收视率的科学、健康、协调的可持续增长。     

中外合作企业中引入有限合伙的相关问题

中外合作企业的数量在改革开放 2 0多年后大大落后于外商投资与中外合资企业 ,其原因部分是中外合作企业法律制度的问题。为促进中外合作企业的发展 ,应引入有限合伙。有限合伙能适应风险投资的发展 ,能解决非法人型中外合作企业法的问题。五部门的规章规定了有限合伙制度 ,是一大发展 ,但在多方面存在缺陷     

Rush and Procrastination Under Hyperbolic Discounting and Interdependent Activities

We analyze the decision of individuals with time-inconsistent preferences to invest in projects yielding either current costs and future benefits or current benefits and future costs. We show that competition between agents for the same project mitigates the tendency to procrastinate on the first type of activities (i.e. to undertake them too late) and to rush on the second one (i.e. to undertake them too early). Competition can therefore increase the expected welfare of each individual. On the contrary, complementarity of projects exacerbates the tendency to rush and to procrastinate and therefore it can decrease the expected welfare of each individual.     

Temptation and Revealed Preference

Gul and Pesendorfer (2001) model the static behavior of an agent who ranks menus prior to the experience of temptation. This paper models the dynamic behavior of an agent whose ranking of menus itself is subject to temptation. The representation for the agent's dynamically inconsistent choice behavior views him as possessing a dynamically consistent view of what choices he “should” make (a normative preference) and being tempted by menus that contain tempting alternatives. Foundations for the model require a departure from Gul and Pesendorfer's idea that temptation creates a preference for commitment. Instead, it is hypothesized that distancing an agent from the consequences of his choices separates normative preference and temptation.
