The Academic Ranking of World Universities (ARWU) has provided annual global rankings of universities since 2003, making it the earliest of its kind. ARWU draws on six indicators to measure the academic performance of universities. Top 500 universities are ranked each year since 2004 by linear combinations of the six indicators. This paper uses a natural log regression model, called the Score-Rank Model, to present the relationship between the score variable and the rank variable for each year from 2004 to 2016. This paper also presents the Trend Model, built by a two-stage process; first, a linear regression model between two parameters ( a t and b t in year t ) is established; and second, an ARIMA model is built to obtain the value of b t . The Trend Model can be used to forecast the overall score of a particular rank, or the rank of a specific overall score for future years. It is shown that the Trend Model is valid in an empirical study using ranking data from 2005 to 2015 to forecast the overall scores of the top 500 ranks in 2016. When comparing the forecast results with the real ranking outcomes of 2016 in a graph, it presents two very similar and almost overlapping curves.

This study investigates an increasingly widespread supply chain system that involves a vendor cyclically supplying specific perishable item to multiple retailers. In general, the vendor has to earlier and accurately determine inventory quantity to meet aggregate demand, and exactly allocate the inventory among a number of retailers to reduce the adjustment costs. Meanwhile, a vital challenge faced for vendors is to develop an efficient inventory- allocation decision model for given perishable item with stochastic and correlated retailer demands during upcoming selling period. To this end, an effective and practical analytical approach, which extends the newsvendor model to incorporate the considered inventory- allocation decision, is proposed here to simultaneously solve the optimal inventory quantity and allocation policy for maximizing expected vendor profits of perishable items. Especially, the lognormal distribution and Ito process is used here to model the behaviors of individual demand shift. Also, an effective integrated approach is presented to work out the aggre- gate demand during next selling period. Finally, numerical experiments are conducted to demonstrate and validate the proposed model and extract the valuable managerial findings.

In the last decade, planning of closed-loop supply chains in different strategic, tactical, and operational levels has attracted many interests due to economic reasons, environmental challenges, and government legislations. This paper presents a novel linear programming model for the integrated production and distribution planning in closed-loop supply chains under uncertainty. The proposed model involves multi-product and multi-period which considers multiple transportation modes, direct or indirect shipments, advertising costs, and several customer zones for different types of products and also attempts to integrate production and distribution plans in the forward and reverse sides of the closed-loop supply chain, simultaneously. To deal with uncertain input data, a robust optimization counterpart based on polyhedral uncertainty set is developed to obtain optimal solutions immunizing the problem for any realization of uncertain parameters in the given polyhedral uncertainty set. Computation results for a numerical example under different scenarios are discussed to give insights about the features of the proposed robust optimization model in handling the uncertainty of parameters. Finally, some sensitivity analyses are performed to show the behaviour of the robust and deterministic models respect to changes of uncertainty levels of parameters as well as the amounts of important parameters such as demands and returns.

Using the original transaction recodes from the Taiwan index options market, this paper is to investigate the trading behaviors of different investors and to capture the information flow between options market and stock market during global financial crisis. In contrast to previous studies, after controlling for the trading volume effects of different exercise prices with the same term-to-expiration, the empirical results show that market investors prefer to trade short-horizon contracts with larger trading liquidity and tend to choose the out-of- the-money options with higher leverage. In addition, there is a significantly reciprocal effect between options market and stock market. When the options trade increases, our findings are also consistent with the pooling equilibrium hypothesis. Particularly, the difference of trades between informed traders and individual investors during global financial crisis has responded to asymmetric information problems. Therefore, this paper concludes that the options trade of foreign institutional investors is more informative, and because of informative advantages, they are probably attracted to out-of-the money options.

Despite the rapid development of optimization techniques, there are still practical multiobjective optimization problems hard to solve, e.g., the large-scale portfolio selection or intensity modulated radiation therapy planning. An effective search among potential decisions to such problems can be time consuming or even beyond allotted limits. To account for this, we propose an interactive multiple criteria decision making scheme with a mix of exact and approximate optimization methods. In that concept, a relatively small set of efficient solutions, so-called shell, is derived by an exact method before the decision making process begins. A shell provides for lower and upper bounds on values of objective functions of efficient decisions and such bounds are easily calculable. During the interactive-iterative decision process such bounds are calculated for decisions corresponding to the decision maker’s temporal preferences. Such bounds serve in the decision making process as replacements for the exact values of the objective functions. Bounds stemming from a shell, if not tight enough to conduct the decision process, can be strengthened by lower bounds provided by so-called lower shells, i.e., sets of feasible decisions approximating the set of efficient decisions, derivable by a population based (inexact) method. We illustrate the operations of the scheme on a selected test problem.

Workplace rituals are influential learning instruments for core values that support organizational culture. However, only limited empirical studies examine how these rituals process to transmit core values in organizational cultures. The aim of this paper is to analyze how the case company uses work songs as a ritual for shaping its organizational culture. The study mainly employed the ritual theory from Smith and Stewart and explored how the organizational members interpret the ritual by examining the features, functions, and mechanisms of the company songs. This study adopted mixed methods, including both qualitative and quantitative approaches. In-depth interviews and questionnaires are utilized for data collection. Prolonged engagement, observation, document review and triangulation techniques have been applied to support the credibility of the study. This paper found that using company songs as a ritual is an effective approach for communicating core values in the case company. The findings provide implications for organizational managers regarding how to effectively use rituals to reach strategic goals for organizational culture management.

Mergers and acquisitions(M&A) are a means of achieving globalization, inorganic growth, accessing the newest technologies, and enhancing capitalization. Glueck [12] indicated M&A is a way that firm pursuit external growth. There are many studies on the abnormal re- turns and announcement effects of mergers and acquisitions, but few papers focus on hostile takeovers. This paper applies the event study method to examine hostile takeovers in the electronic industry around the world and delve into the abnormal returns of the acquirers and the targets. The data on hostile takeovers in 1981-2016 are sourced from Security Data Company (SDC). The historical share prices are obtained from DataStream. The purpose is to validate the presence of significant abnormal returns on acquirers and targets and compare the abnormal returns between the acquirers and the targets, as well as between non-electronic industry companies and electronic industry companies in hostile takeovers.

The development and process quality of badminton rackets are important issues for sports product manufacturers. The shaft connects the handle and the racket head. Aside from the material of the shaft, the roundness of the two ends is a significant quality characteristic. However, a comprehensive review reveals little existing research assessing the process quality of shaft roundness in badminton rackets. This study employed a process capability index to develop a hypothesis-testing procedure for the assessment of process quality with regard to shaft roundness in badminton rackets. Using a case study of the badminton racket of manufacturer T, the implementing process of the proposed approach was demonstrated. This study also presents a lookup table of various PCI values, yield rates, and hypothesis-testing critical values corresponding to different quality levels for industrial use. The proposed approach fills the current gap in academic research and industrial practice.

This study developed a mathematical programming model to determine confidence intervals of S_(pk) by converting index S_(pk) into a function of μ_y = (μ - T ) and σ_y =σ/d, constructing the feasible region of joint confidence interval with μ_y and σ_y, and then regarding S_(pk)(μ_y, σ_y) as an objective function, to overcome the shortage of point-estimate and interval-estimate calculations of the past process capability index. Then, Monte Carlo simulation was used to analyze the coverage rate in order to validate the accuracy of the proposed method. Our results demonstrate the efficacy of the proposed evaluation model using quartz crystal oscillators, a passive component commonly used in communication devices. The proposed method eliminates the complex complexity of statistical methods, and the results are optimal values largely robust to errors. The proposed model can also be applied to other complex process evaluation indices, thereby presenting manufacturers with an efficient and convenient method for the assessment of process capability.

In practice, quality managers often employ sampling inspection to test and evaluate process performance or product quality instead of a 100% inspection, owing to cost and time considerations. Based on this factor, this article develops a smaller-the-better process capability analysis model (SBPCAM) to measure whether process capability of a product with multiple quality characteristics conforms to customer requirements, based on the process capability index (PCI) of smaller-the-better C_(pu) with the functions of the accuracy index (A) and the precision index (P). In the proposed method, a control chart with joint confidence blocks (JCB) is used to reduce sampling error and to improve the reliability of the point estimate of index C_(pu). A numerical example is provided to illustrate the feasibility and effectiveness of the proposed method.
