考虑重复购买因素的品牌竞争对新产品扩散的影响研究——基于小世界网络的仿真环境

在对品牌竞争影响要素分析的基础上,考虑重复购买在新产品扩散过程中的调节效应,构建以消费者微观采纳机制为核心的新产品扩散的阈值模型,在小世界网络仿真情境下,运用多智能仿真方法对品牌竞争与新产品扩散之间的影响关系进行分析,研究结果表明：转换成本对新产品扩散的速度和深度的影响存在一定的"条件区域",在该区域之外两者不存在显著的影响关系;进入时间与两种竞争性品牌的扩散速度存在一致的负向的影响关系,而对两种竞争性品牌的扩散深度的影响方向则相反;在此过程中,重复购买系数起着一定的调节效应,会在一定程度上放大或缩小转换成本及进入时间对新产品扩散的影响效应。通过本文的研究,不仅可以进一步丰富和完善竞争性产品创新扩散的相关理论,也可以为企业的新产品推广实践提供决策支持。     

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.     

江西省企业技术创新中新产品的发展态势

新产品在技术创新中的地位越来越重要,江西省新产品产值、新产品出口创汇今后三年中仍以大于10%的速度增长。尽管全省企业知识产权保护的意识明显加强,但国外专利数偏少（占0.63%）,具有自主知识产权的高精尖端技术不强。必须完善全省科技人才吸引和激励机制,加大力度引进高层次创新人才,加大力度落实科技创新优惠扶持政策,加大力度给予经费扶持。同时必须健全产学研紧密结合的机制,提升企业自主创新能力,增强企业技术集成与产业化能力。     

Analysis of robust design experiments with time-dependent ordinal response characteristics: a quality improvement study from the horticulture industry

An approach to the analysis of time-dependent ordinal quality score data from robust design experiments is developed and applied to an experiment from commercial horticultural research, using concepts of product robustness and longevity that are familiar to analysts in engineering research. A two-stage analysis is used to develop models describing the effects of a number of experimental treatments on the rate of post-sales product quality decline. The first stage uses a polynomial function on a transformed scale to approximate the quality decline for an individual experimental unit using derived coefficients and the second stage uses a joint mean and dispersion model to investigate the effects of the experimental treatments on these derived coefficients. The approach, developed specifically for an application in horticulture, is exemplified with data from a trial testing ornamental plants that are subjected to a range of treatments during production and home-life. The results of the analysis show how a number of control and noise factors affect the rate of post-production quality decline. Although the model is used to analyse quality data from a trial on ornamental plants, the approach developed is expected to be more generally applicable to a wide range of other complex production systems.     

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.     

论大学英语教学中交际能力的培养

一直以来,国内英语界将"英国英语"或者"美国英语"视为标准英语。这种观念也深深植根于大学英语教师之中,并由教师在课堂教学中灌输给了学生。在这种观念影响之下,大学教师及大学学生无一例外,都将"英国英语"或"美国英语"视为正统,低估甚至歧视各种英语变体的存在,"China English"就是一个例子。笔者认为,恰恰就是这种旧观念极大地影响了大学英语教学中学生交际能力的培养。英语实际上是一门国际语言,应当作为跨国及跨文化交流的共通语,随着越来越多的人开始认识并逐步接受这一新观念,大学英语教学对学生交际能力培养效率低下这一尴尬现状有了改观的可能。     

论TRIPS协议框架下我国纺织品外观设计保护制度的建立

TRIPS协议对纺织品外观设计提出了特殊的保护要求,允许各成员国自由选择是以著作权法还是以工业品外观设计法对纺织品外观设计进行保护,对此我国法律没有相关规定。文章在比较著作权保护与工业产权保护二者之优劣的基础上,分析借鉴他国立法,对在我国建立对纺织品外观设计提供双重保护的法律制度提出了建议。     

河北省红色旅游产品开发研究

针对2004年以来河北省红色旅游的发展历程,河北省红色旅游产品开发中主要存在缺乏市场调查、产品开发层次比较肤浅、红色旅游品牌产品比较缺乏等问题,结合红色旅游发展的目标和实际需求,提出河北省红色旅游产品发展应该注重规划的与时俱进、市场调研的充分性、深度开发以提高产品的吸引力及打造红色旅游品牌产品等适合于河北省红色旅游产品开发的对策。     

价格不明合同合理价格的确定--新合同法第62条之不足与补救办法

对于价格不明合同的价格确定问题,我国新合同法和各国民商法的规定,在许多情况下无法适用,出现了立法上的缺漏,造成了实务上的无法可依,建议对新合同法第62条作三点补充解释1.没有相同产品的,可依争议产品之同类产品或者近似产品在合同订立时履行地市场类似交易中的正常销售价为可比价,确定争议产品的公平价格;2.争议产品之同类产品,在合同订立时的履行地市场未曾销售或者虽有销售,但销售数量、价格,不能作为公平价格进行比较的,可依该同类产品在适当的其他地区正常销售时的可比价格确定争议产品的公平价格;3.如果上述规定均不宜适用,可以争议产品之同类产品或者争议产品本身的生产成本加税费、合理利润和其他费用之和为其公平价格.
