河南高等教育高水平发展略论

"十五"期间,河南高等教育事业取得突飞猛进的发展,但与广大人民群众"有学上"、"有好学上"的需求仍有一定差距,服务河南经济社会发展的能力还不够强,根源主要在于河南高等教育优质资源比较匮乏,突出表现在重点大学、重点学科和重点实验室较少方面.推动河南高等教育高水平发展,必须有针对性地加大"三重"建设力度,在学科建设等五个方面狠下工夫.     

Improved model selection criteria for SETAR time series models

The purpose of this paper is threefold. First, we obtain the asymptotic properties of the modified model selection criteria proposed by Hurvich et al. (1990. Improved estimators of Kullback-Leibler information for autoregressive model selection in small samples. Biometrika 77, 709–719) for autoregressive models. Second, we provide some highlights on the better performance of this modified criteria. Third, we extend the modification introduced by these authors to model selection criteria commonly used in the class of self-exciting threshold autoregressive (SETAR) time series models. We show the improvements of the modified criteria in their finite sample performance. In particular, for small and medium sample size the frequency of selecting the true model improves for the consistent criteria and the root mean square error (RMSE) of prediction improves for the efficient criteria. These results are illustrated via simulation with SETAR models in which we assume that the threshold and the parameters are unknown.     

Ecocultural Attributes: Evaluating Ecological Degradation in Terms of Ecological Goods and Services Versus Subsistence and Tribal Values

It is becoming increasingly clear that scientists, managers, lawyers, public policymakers, and the public must decide how to value what is provided by, and is a consequence of, natural resources. While “Western” scientists have clear definitions for the goods and services that ecosystems provide, we contend that these categories do not encompass the full totality of the values provided by natural resources. Partly the confusion results from a limited view of natural resources derived from the need to monetize the value of ecosystems and their component parts. Partly it derives from the “Western” way of separating natural resources from cultural resources or values, and partly it derives from the false dichotomy of assuming that ecosystems are natural, and anything constructed by man is not natural. In this article, we explore the previous assumptions, and suggest that because cultural resources often derive from, and indeed require, intact and unspoiled natural ecosystems or settings, that these values are rightly part of natural resources. The distinction is not trivial because of the current emphasis on cleaning up chemically and radiologically contaminated sites, on restoration of damaged ecosystems, on natural resource damage assessments, and on long‐term stewardship goals. All of these processes depend upon defining natural resources appropriately. Several laws, regulations, and protocols depend upon natural resource trustees to protect natural resources on trust lands, which could lead to the circular definition that natural resources are those resources that the trustees feel they are responsible for. Where subsistence or tribal peoples are involved, the definition of natural resources should be broadened to include those ecocultural attributes that are dependent upon, and have incorporated, natural resources. For example, a traditional hunting and fishing ground is less valued by subsistence peoples if it is despoiled by contamination or physical ecosystem degradation; an Indian sacred ground is tarnished if the surrounding natural environment is degraded; a traditional homeland is less valued if the land itself is contaminated. Our argument is that intact natural resources are essential elements of many cultural resources, and this aspect requires and demands adequate consideration (and may therefore require compensation).     

Three Kinds of Anti-Intellectualism: Rethinking Hofstadter*

Hofstadter's landmark analysis of anti-intellectualism in American life is interpreted within the framework of the sociology of knowledge. His analysis suggests three analytically distinct types of anti-intellectualism: religious anti-rationalism, populist anti-elitism, and unreflective instrumentalism. Each type arises from within its own distinctive institutional matrix. Although Hofstadter fails to anticipate the growing cultural impact of mass media institutions, he demonstrates convincingly that anti-intellectualism is not a unitary phenomenon.     

Parent‐Adolescent Involvement: The Relative Influence of Parent Gender and Residence

The 1995 wave of the Add Health study is used to investigate the relative influence of parent gender and residence on patterns of parental involvement with adolescents. Adolescent reports (N =17,330) of shared activities, shared communication, and relationship quality with both biological parents are utilized. A multidimensional scaling analysis reveals that parent gender explains most of the variance in parent‐adolescent involvement, with residential status playing a secondary yet a fundamental role in accounting for these patterns. Resident mothers who do not live with adolescents’ biological fathers engage in the broadest range of activities with their children. Unpartnered resident fathers display patterns of parenting that are as similar to mothers as they are to other fathers.     

王船山的《中庸》首章诠释及其思想

以《中庸》为个案 ,从宋明道学的视野来观察船山的《四书》诠释。可以认为 :船山读《中庸》说 ,其中以未发说和戒慎说为其核心。船山有关《中庸》的讲法 ,可以说是“接着”程朱讲的 ,但不是“照着”程朱讲的 ;他不是传统意义上的程朱学派 ,但受到程朱学派的较大影响。船山虽然并不承认自己为程朱学派的一员 ,但顺承程朱《中庸》解说的脉络 ,延续程朱《中庸》诠释的问题性 ,吸取程朱许多的理学观念和诠释学资源 ,同时又针对朱子本人及朱门后学的论点而提出自己的诠释主张。船山的《中庸》解释是明清之际儒学经典诠释的一部分     

Two earner family migration A search theoretic approach

This paper represents the first attempt to model the two earner family decision to migrate using a joint search theoretic approach. In so doing, the paradox of a couple whose members would both migrate if single but decide not to migrate because they are married to each other is discovered and explained. Furthermore the impact of the rising number of working women and reentry of wives into the labor force on the extent and regional pattern of migration is discussed. Extensions to the model are addressed, as well as future avenues of research, both theoretical and empirical. It is suggested that the search theoretic approach, not previously applied to models of family migration, is the most appropriate.     

企业诚信影响全要素生产率吗? ——基于纳税诚信的经验证据

企业诚信不仅是良好市场经济秩序的基础,同时也是经济高质量发展的重要内容.本文以国家税务总局公布的2014—2018年上市公司纳税诚信状况作为企业诚信的衡量指标,考察企业诚信经营对企业全要素生产率的影响.研究发现,诚信企业的全要素生产率显著高于非诚信企业;企业诚信会通过促进研发创新以及优化内部控制来提高企业全要素生产率.异质性分析表明,企业诚信对低市场化进程地区企业、国有企业全要素生产率的促进作用更为显著.研究结论不仅为推进我国企业诚信建设提供经验证据,也为企业转型升级、实现高质量发展提供路径参考.
