中日纺织服装产业贸易的竞争与互补性分析

经历过1998和2009年的金融危机让中日两国纺织服装产业联系更为紧密也让竞争更为明显,在此以两国纺织品服装进出口贸易数据为基础测算了两国比较优势和贸易互补性程度。结果表明：中日互为双方纺织品服装贸易的重要进出口市场,两国纺织服装产业比较优势各有不同,贸易互补性很强,产业合作会产生双赢局面。

Bodywork Boundaries: Power,Politics and Professionalism in Therapeutic Massage

In the last decade or so, complementary and alternative medicine generally, and therapeutic bodywork in particular, has been attempting to enhance its professional status and standing. By focusing upon the sex/gender dimensions of therapeutic massage and the wider historical, cultural and legal contexts in which such work is situated, this article explores and analyses the discursive formations and practices which women therapeutic massage practitioners deploy in the course of their attempts to achieve professional recognition. Drawing upon both primary and secondary data, it is argued that particular difficulties pertain in the case of the professionalization of therapeutic massage. Because of the widespread elisions between massage and sex work, women therapeutic massage practitioners have to mark out their professional distance from clients by deploying professional identifications and by using boundary‐setting devices or techniques which act to distinguish them from sex workers. This article explores these discursive formations and practices and argues that they act to create near‐intractable problems for women massage practitioners. The article concludes that, because these issues are not commonly acknowledged in much of the academic, policy or practitioner‐orientated literature, the neglect of sex/gender in the case of therapeutic massage has consequences not only for the professionaliza‐tion project of this particular therapeutic modality but for the ways in which various body work occupations in which women predominate tend to be seen as marginal and illegitimate ‘professions’.     

互补型闭环供应链的收益共享与成本共担契约协调优化

互联网平台开放、协作和分享的特点改变了传统的商业模式。如何将互联网思维与传统产业相融合,理论界和实业界正在进行理论探索和模式实践,突破线上平台商和线下渠道服务商界限以提高服务效率,解决线上平台服务和逆向回收难的瓶颈。本文针对单一线上平台商-单一线下渠道服务商的闭环供应链系统,探讨双方如何在正向供应链进行收益共享、逆向供应链进行渠道成本分担情境下的产品定价和服务优化决策。通过对比收益共享模型和收益共享-成本共担模型发现,线上平台商将部分收益分给线下服务商的同时,如果能分担线下渠道服务建设投入,将更有利于逆向回收和服务商逆向渠道服务水平的提高。最后,还通过数值分析,验证了分成分担比例对平台商和服务商决策的影响,以及对各决策变量的影响关系机理。     

基于学习和能力互补动态的研发联盟稳定性研究

合作研发是企业创新的常用战略措施,然后合作研发却常常不能维持较长时间,而且比较松散的合作形式逐渐成为主流。本文在Sinha&Cusumano模型基础上,通过引入学习因素,对互补因子进一步进行考察,利用互补因子的变化解释了上述现象产生的原因,也为选择研发合作伙伴提供了一个参考依据,即考察对方合作动机中的能力互补与学习因素,避免合作意外或较早终止。     

飞行频率、拥挤成本和互补型航空联盟:中枢轮辐网络机场拥挤分析

本文在基于飞行频率、拥挤成本和互补型航空联盟的基础上系统分析了中枢轮辐网络机场拥挤问题。研究表明:航空公司的利润最大化使得航班飞行频率存在过度供给,飞机大小也是次优的,这进一步恶化了中枢机场的机场拥挤;航班飞行频率与航空公司的拥挤成本系数、旅行计划延迟效用系数正相关,与飞机每次起降的固定成本负相关;互补型航空联盟使得联盟体利润增加,航空联盟对连接市场乘客有利,对本地市场乘客不利,航空联盟还可以内化伙伴间拥挤,航班飞行频率得以优化,机场拥挤得以缓解。     

Recursive computation of the single and product moments of order statistics from the complementary exponential–geometric distribution

The complementary exponential–geometric distribution has been proposed recently as a simple and useful reliability model for analysing lifetime data. For this distribution, some recurrence relations are established for the single and product moments of order statistics. These recurrence relations enable the computation of the means, variances and covariances of all order statistics for all sample sizes in a simple and efficient recursive manner. By using these relations, we have tabulated the means, variances and covariances of order statistics from samples of sizes up to 10 for various values of the shape parameter θ. These values are in turn used to determine the best linear unbiased estimator of the scale parameter β based on complete and Type-II right-censored samples.     

The Poisson–exponential distribution: a Bayesian approach

In this paper, we proposed a new two-parameter lifetime distribution with increasing failure rate. The new distribution arises on a latent complementary risk scenario. The properties of the proposed distribution are discussed, including a formal proof of its density function and an explicit algebraic formulae for its quantiles and survival and hazard functions. Also, we have discussed inference aspects of the model proposed via Bayesian inference by using Markov chain Monte Carlo simulation. A simulation study investigates the frequentist properties of the proposed estimators obtained under the assumptions of non-informative priors. Further, some discussions on models selection criteria are given. The developed methodology is illustrated on a real data set.
