国内外产学研结合模式发展状况及启示

产学研是当今国内外普遍采用的促进企业经济社会效益的形式,具有快捷性、高科技性以及高效益性等特征。国内常采取建立联合创新平台、实行“学工交替”及“高校＋政府＋企业”、共建大学科技园等模式,而国外则启动国家科技创新计划、建立产学研合作组织、构建产学研合作目标、加快制度建设等,促进产学研有机结合。因此,我们要加快产学研立法工作,形成一整套促进产学研结合的信息沟通机制、双方互动机制、人才流动机制、成果评价体系,同时紧密结合地方实际进行产学研结合。

商会的产生机理:一个利他主义的解释

对于只提供集体公共产品的商会来说,如果行业内的企业都是利己主义者,且加入商会完全自愿,则"搭便车"的行为会使得集体行动无法实现,商会的发生机制亦将成为难解之迷。假如行业中存在利他主义的企业,其利他行为将使其他企业意识到行业的共同利益,从而抑制各自的机会主义倾向。利他主义者的存在起到了一种"凝结核"的作用,他们除了付出物质上的代价去增进行业的共同利益外,还会付出时间和精力去游说其他企业,推动行业的集体行动。多数行业的市场结构是不完全竞争的,企业规模参差不齐,一些规模较大的企业对于通过集体行动来获得合作剩余有着更强烈的需求,为了增进自身利益和整个集团的利益,这些规模较大的企业会成为商会的发起人。

Joint GEEs for multivariate correlated data with incomplete binary outcomes

This study considers a fully-parametric but uncongenial multiple imputation (MI) inference to jointly analyze incomplete binary response variables observed in a correlated data settings. Multiple imputation model is specified as a fully-parametric model based on a multivariate extension of mixed-effects models. Dichotomized imputed datasets are then analyzed using joint GEE models where covariates are associated with the marginal mean of responses with response-specific regression coefficients and a Kronecker product is accommodated for cluster-specific correlation structure for a given response variable and correlation structure between multiple response variables. The validity of the proposed MI-based JGEE (MI-JGEE) approach is assessed through a Monte Carlo simulation study under different scenarios. The simulation results, which are evaluated in terms of bias, mean-squared error, and coverage rate, show that MI-JGEE has promising inferential properties even when the underlying multiple imputation is misspecified. Finally, Adolescent Alcohol Prevention Trial data are used for illustration.     

Development of sustainable platform for modular product family: a case study

Abstract

Defining product platform architecture is a critical issue to design and develop product variants. Different factors are highly dependent on the architecture type, such as number of variants, to measure modularity level, component commonality, market demand, etc. It is directly related to manage product portfolios and setting up business plan of a company. Before defining a product platform, whether it is modular or integral product designers need to follow specific design guidelines and checklists. This research mainly focuses on to define the platform architecture as well as provides necessary design guidelines and checklists for the product designers. It also highlights an example product of a case company with the objective to clarify/validate the proposed product design approach. In conclusion, this paper outlines the findings from this research and proposed some critical questions need to be answered within the scope of future research potentials.     

Decision model for product rollover in manufacturing operations

The purpose of this study is to investigate critical decisions when planning for product rollover at a manufacturing company, and how to organise these decisions. A literature review and a case study are used to develop a decision model. The findings indicate that product rollover can be organised in a five-phase decision model. The research quality is strengthened by a structured literature review, but it can be argued that more empirical research is needed for validation. For researchers, this paper contributes with the identification of critical decisions and a model for product rollover. For practitioners, the study highlights the need to acknowledge the importance of product rollover and its role as a competitive weapon. In earlier studies, product rollover has mainly been investigated from a market perspective, so that this study contributes by investigating the issue from a manufacturing perspective.     

教师职业素养新论

国家于2010年新出台的《国家中长期教育改革和发展规划纲要(2010——2020年)》(以下简称《教育规划纲要》),使教师的职业素养再度引起公众的关注。文章将其归结为"敦品"、"业精"、"敬业"六个字,并从这三个方面入手谈教师的职业素养。     

关于精神文化产品的哲学思考

精神文化产品是以观念形态存在并以一定的物质为载体得以呈现的产品,是精神文化生产者劳动智慧的结晶。社会效益为精神文化产品创作生产导向,经济效益是讲求社会效益的基础。弘扬主旋律,提倡多样化,是把握先进文化的前进方向,发展社会主义文化的根本要求和指导原则,也是指导精神文化产品创作和生产的根本要求和指导原则。精神文化产品的创作生产要坚持先进文化的大众性与文化精品的贴近性的结合。精神文化产品消费是较高层次上的商品消费活动,是商品消费与精神享受的辩证统一。     

生态旅游与旅游生态化辨析

10多年来,生态旅游在中国的发展虽然很快,但理论上悬而未决的争论还较多,集中表现在生态旅游是旅游产品还是旅游发展模式、生态旅游是高档旅游还是大众旅游、生态旅游对象是自然区域还是可以包括地方文化区域等三个方面。同时在发展过程中,生态旅游在中国的实践中也出现了很多非生态化现象和"泛化"现象。这些现象的出现归根结底是由于将生态旅游与旅游生态化混为一谈造成的。本文通过对"生态旅游"、"旅游生态化"的辨析,对相关问题作了初步解答,并试图还原生态旅游的本意,探索今后生态旅游发展的正确途径。
