全渠道零售场景下配送车辆路径问题

为研究全渠道零售的配送系统对企业物流成本的影响,综合考虑时间窗、车型选择等因素,以运输成本最低为目标,建立高度协同的全渠道零售场景下的物流配送模型。该模型采用自适应遗传算法求解,利用MATLAB进行算例分析。结果显示:全渠道零售模式下的车辆调度方案能迅速响应消费者需求,与一般配送模式相比可以减少物流成本,优化车辆配置。与粒子群优化算法相比,自适应遗传算法的运行时间更短、优化结果更好,这验证了模型和算法的可行性和有效性。

An analysis of the value of multiple mentors in formalised elite coach mentoring programmes

Background: Within the context of sports coaching and coach education, formalised mentoring relationships are often depicted as a mentor–mentee dyad. Thus, mentoring within sports coaching is typically conceptualised as a one-dimensional relationship, where the mentor is seen as the powerful member of the dyad, with greater age and/or experience [Colley, H. (2003). Mentoring for Social Inclusion. London: Routledge].

Aim: The aim of this study was to explore the concept of a multiple mentor system in an attempt to advance our theoretical and empirical understanding of sports coach mentoring. In doing so, this paper builds upon the suggestion of Jones, Harris, and Miles [(2009). “Mentoring in Sports Coaching: A Review of the Literature.” Physical Education and Sport Pedagogy 14 (3): 267–284] who highlight the importance of generating empirical research to explore current mentoring approaches in sport, which in turn can inform meaningful formal coach education enhancement. The significance of this work therefore lies in opening up both a practical and a theoretical space for dialogue within sports coach education in order to challenge the traditional dyadic conceptualisation of mentoring and move towards an understanding of ‘mentoring in practice’.

Method: Drawing upon Kram’s [(1985). Mentoring at Work: Developmental Relationships in Organisational Life. Glenview, IL: Scott Foresman] foundational mentoring theory to underpin a multiple mentoring support system, 15 elite coach mentors across a range of sports were interviewed in an attempt to explore their mentoring experiences. Subsequently, an inductive thematic analysis endeavoured to further investigate the realities and practicalities of employing a multiple mentoring system in the context of elite coach development.

Results: The participants advocated support for the utilisation of a multiple mentor system to address some of the inherent problems and complexities within elite sports coaching mentoring. Specifically, the results suggested that mentees sourced different mentors for specific knowledge acquisition, skills and attributes. For example, within a multiple mentor approach, mentors recommended that mentees use a variety of mentors, including cross-sports and non-sport mentors.

Conclusion: Tentative recommendations for the future employment of a multiple mentoring framework were considered, with particular reference to cross-sports or non-sport mentoring experiences.

Abstract

This study analyzes Japanese and Korean ethno-national (minzoku-kokumin) education in postwar Japan. During a period of political unrest in Japan (1945–1955), some of the Korean residents and Japanese worked together to overcome the culture of Imperial Japan and its assimilative education. They also regarded themselves as people colonized by the United States, and pursued a political-cultural movement for their liberation and independence from American imperialism. The Koreans in Japan rejected compulsory education in the Japanese language. As a result, since 1956, Korean schools (Chōsengakkō), funded and supported by North Korea, were founded all across Japan. Their ethno-national education was in fact incorporated into North Korean politics, and has been considered in many studies as having overcome Japanese assimilation and ethnic inequalities. Such a view was a result of many academic Zainichi Korean studies that come from an “insider's perspective” to criticize Japanese colonialism and discrimination. In order to go beyond this insider's view, I focus on the political alliance between Zainichi Koreans and the Japanese people in their pursuit of ethno-national education. Since 2010, the Japanese state funding for Korean schools has become a major controversy in Japan. By tracing the historical background, this article intends to explain why this political issue has arisen. The ultimate purpose of this article is to suggest an ethical perspective to resolve the current political conflict regarding Korean schools in Japan.     

一个带协变量调整多响应比较的高效方法及其在基因组数据中的应用

目前在文献中有很多关于多响应比较的研究方法,但是对带协变量调整的非参数检验的研究较少。一种直观的想法是将数据先投影到协变量的正交空间中,然后再利用秩和检验、调整的秩和检验或最大值检验方法。但是,功效普遍不高。在调整的秩和检验和伪F检验两种方法基础上,构建MIN2检验。大量模拟和实际数据表明,MIN2检验的效果优于现有的非参数检验方法。     

简述译者在翻译过程中的多重身份

二十世纪七十年代后,西方翻译研究中文化观点的转变赋予了翻译学习新的特点与研究方法。以目标语为导向的翻译方法就出自这场转变,对翻译过程中译者的文化身份及角色进行了重申。逐渐,学者们也真正认识到译者才是翻译的主体,才是翻译过程中不可或缺的一部分。然而,在长期的翻译研究中,译者的身份一直未得到过明确的认可及肯定,因此难免对翻译学习造成了大量消极的影响。

Patron-Driven Acquisition and Circulation at an Academic Library: Interaction Effects and Circulation Performance of Print Books Acquired via Librarians’ Orders,Approval Plans,and Patrons’ Interlibrary Loan Requests

Numerous publications on patron-driven acquisition (PDA) for print books and similar materials have reported that patron-requested materials circulate more. Tying circulation to selector may be failing to address the complex of factors that contributes to items' circulation. In the present study, the authors revisit a PDA program's data and to determine whether PDA print books' circulation advantage persists when the potential interactions of several additional variables are taken into account. As with prior studies, library patrons were significantly better predictors of circulation than were librarians or approval plans. However, librarians proved to be significantly better predictors than were approval plans.     

Predicting ground reaction forces in running using micro-sensors and neural networks

Measurement of ground reaction force (GRF) in running provides a direct indication of the loads to which the body is subjected at each foot-ground contact, and can provide an objective explanation for performance outcomes. Traditionally, the collection of three orthogonal component GRF data in running requires an athlete to complete a series of return loops along a laboratory based runway, within which a force platform is embedded, in order to collect data from a discrete footfall. The major disadvantages associated with this GRF data collection methodology include the inability to assess multiple consecutive foot contacts and the fact that measurements are typically confined to the laboratory. The objective of this research was to investigate the potential for wearable instrumentation to be employed, in conjunction with artificial neural network (ANN) and multiple linear regression (MLR) models, for the estimation of GRF in middle distance running. A modular wearable data acquisition system was developed to acquire in-shoe force (ISF) data. Matched data sets from wearable instrumentation (source data) and force plate (target data) records were collected from elite middle-distance runners under controlled laboratory conditions for the purposes of ANN and MLR model development (MD) and model validation (MV). In terms of statistical measures of prediction accuracy the MLR model was found to provide a superior level of accuracy for the prediction of the vertical and medio-lateral components of GRF and alternatively, the ANN model provided the most accurate predictions of the anterior-posterior component of GRF. The prediction accuracy of each component of GRF was found to be governed by the inherent signal variability, in which case the vertical and anterior-posterior components were more reliable and subsequently predicted significantly more accurately than the medio-lateral component. The emerging capability for obtaining continuous GRF records from wearable instrumentation has the potential to permit unprecedented quantification of training stress and competition demands in running.
