企业社会责任与和谐劳动关系构建

结合以SA8000标准为代表的企业社会责任运动,本文将企业的成本收益纳入分析框架,通过动态最优化博弈模型考察SA8000是否有利于改善我国转型期较紧张的企业劳动关系。研究表明,在其他条件不变的情况下,我国企业缺乏改善劳动关系的动力;SA8000的影响力、国外企业的劳动关系投入等与改善劳动关系呈正相关,而通过SA8000认证的费用与其负相关;企业利润与改善劳动关系之间并非绝对的不相容,在保证企业利润的前提下,SA8000有利于改善我国企业劳动关系。

Marketing research and revenue optimization for the cruise industry: A concise review

This paper presents a concise review of the cruise industry mainly from marketing research and revenue optimization prospects. In recent years, the cruise industry has experienced an exciting growth. However, as one of the fastest growing and most profitable categories in the entire leisure market, this industry has hardly received any research attention. Given the limited academic articles, this paper presents a concise review about this budding research topic. First of all, a discussion about global cruise industry is conducted. Then, academic studies of the cruise industry on general marketing research, revenue management, itinerary design/optimization, optimal market segmentation, demand infiltration and economic issues are reviewed. Finally, some promising directions for future research are presented.

Forecast of realized covariance matrix based on asymptotic distribution of the LU decomposition with an application for balancing minimum variance portfolio

We derive the asymptotic distribution for the LU decomposition, that is, the Cholesky decomposition, of realized covariance matrix. Distributional properties are combined with an existing generalized heterogeneous autoregressive (GHAR) method for forecasting realized covariance matrix, which will be referred to as a generalized HARQ (GHARQ) method. An out-of-sample forecast comparison of a real data set shows that the proposed GHARQ method outperforms other existing methods in terms of optimizing the variances of portfolios.

A New Decision Making Model for Subcontractor Selection and Its Order Allocation

All experts agree on the importance of subcontracting. The high impact of subcontractors on the construction process means that the selection of subcontractors is a sensitive activity. Previous investigations documented the selection of subcontractors based on criteria but did not consider the number of subcontracted tasks. This paper explores allocating the best portion of tasks to subcontractors while optimizing the risk and cost in the fixed project schedule. The study's main finding demonstrates that subcontractor selection without attention to the order allocation is not a realistic approach; therefore, a hybrid model that applies continuous ant colony and fuzzy set theory is proposed.
