A Cramér-type large deviation theorem for sums of functions of higher order non-overlapping spacings

Let U ₁, U ₂, . . . , U _n–1 be an ordered sample from a Uniform [0,1] distribution. The non-overlapping uniform spacings of order s are defined as \({G_{i}^{(s)} =U_{is} -U_{(i-1)s}, i=1,2,\ldots,N^\prime, G_{N^\prime+1}^{(s)} =1-U_{N^\prime s}}\) with notation U ₀ = 0, U _n = 1, where \({N^\prime=\left\lfloor n/s\right\rfloor}\) is the integer part of n/s. Let \({ N=\left\lceil n/s\right\rceil}\) be the smallest integer greater than or equal to n/s, f _m (u), m = 1, 2, . . . , N, be a sequence of real-valued Borel-measurable functions. In this article a Cramér type large deviation theorem for the statistic \({f_{1,n} (nG_{1}^{(s)})+\cdots+f_{N,n} (nG_{N}^{(s)} )}\) is proved.     

Two-stage flowshop earliness and tardiness machine scheduling involving a common due window

This paper studies a non-preemptive two-stage flowshop scheduling problem to minimize the earliness and tardiness under the environment of a common due window. The window size and the window location are considered to be given parameters. The just-in-time problem exists naturally and has many practical applications. The problem is shown to be NP-complete in the strong sense. We develop a branch and bound algorithm and a heuristic to solve the problem. We conduct the computational experiments to test the performances of the algorithms. A strong lower bound is derived for the branch and bound algorithm that can efficiently solve 15 jobs problem for about 5 minutes. The heuristic is shown to be efficient and effective, which can solve the problem of 150 jobs for about 20 seconds and provide near-optimal solution. We justify that the heuristic is an excellent solution approach for large problem instances. We also show that four special cases are either polynomial solvable or NP-complete in the ordinary sense.     

Can the affordable care act provisions explain the recent wave of acquisitions in the health insurance industry?

This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year.     

International Marketing Ethics from an Islamic Perspective: A Value-Maximization Approach

International marketing practices, embedded in a strong ethical doctrine, can play a vital role in raising the standards of business conduct worldwide, while in no way compromising the quality of services or products offered to customers, or surrendering the profit margins of businesses. Adherence to such ethical practices can help to elevate the standards of behavior and thus of living, of traders and consumers alike. Against this background, this paper endeavors to identify the salient features of the Islamic framework of International Marketing Ethics. In particular, it highlights the capabilities and strengths of this framework in creating and sustaining a strong ethical international marketing culture. At the heart of Islamic marketing is the principle of value-maximization based on equity and justice (constituting just dealing and fair play) for the wider welfare of the society. Selected key international marketing issues are examined from an Islamic perspective which, it is argued, if adhered to, can help to create a value-loaded global ethical marketing framework for MNCs in general, and establish harmony and meaningful cooperation between international marketers and Muslim target markets in particular.     

Human resource information systems: Information security concerns for organizations

We explore HRIS and e-HR security by presenting information security fundamentals and how they pertain to organizations. With increasing use of enterprise systems such as HRIS and e-HR, security of such systems is an area that is worthy of further exploration. Even then, there is surprisingly little research in this area, albeit that extensive work is present in regard to HRIS privacy. While focusing on HRIS and e-HR security, we introduce aspects of HRIS and e-HR security and how it can be enhanced in organizations. A research model is also presented along with propositions that can guide future research.     

Application fee manipulations in matching markets

In some well-known hospital–intern type of matching markets, hospitals impose mandatory application fees on internship applicants to consider their applications. Motivated by this real-life phenomenon, we study the application fee overreporting incentives of hospitals in centralized matching markets by assuming that interns have finite budgets to spend on such fees. Our main theorem shows that no stable mechanism is immune to application fee manipulations. Interestingly, under any stable rule, hospitals might not only obtain better matchings but also increase their application fee revenues through overreporting their application fees. In the restricted domains in which either side has homogeneous preferences or each hospital has only one available position, every stable mechanism turns out to be immune to application fee overreportings.     

Universal service in Turkey: Recent developments and a critical assessment

The meaning of universal service in telecommunications has changed considerably in the last decade. Technological advances have created the necessity to redefine the legal framework. While the demand for old universal services falls, new and wider services are to be included in the scope of legal obligations such as broadband. In this transformation of public policy toward universal services, political preferences take precedence over economic considerations. Turkey provides a good case in point. In this paper, the authors assess the legal framework of universal services and its institutional structure in Turkey. The tension between enlarging the scope of universal service and pressures on using revenues efficiently is emphasized.     

Competition law and regulation in the Turkish telecommunications industry: Friends or foes?

The interaction between national competition authorities (NCAs) and national regulatory authorities (NRAs) plays a vital role in institutionalizing competition policy during regulatory reforms. Questions about jurisdictional authority over competition policy are far from settled     

Differences by mother’s education in the effect of childcare on child obesity

Previous studies have found adverse effects of maternal employment on child obesity for higher educated mothers. Using a quasi-structural model, we find additionally a lower risk of obesity for children of less educated mothers with increased time in non-parental childcare.     

The Pivotal Role of User-Friendly Food Label and Personality Traits on Intention to Consume Packaged Food Products

The objective of the present study was to examine the effect of friendly food labels on packaged food consumption intention. A questionnaire method was adopted for data collection. The data were collected from 14 Pakistani universities. The systematic random sampling technique was used to draw the required sample size. The sample size was 365, where 730 questionnaires were distributed among students of 14 universities to achieve the required sample. Findings disclosed that a friendly food label has a positive and significant relation with packaged food consumption intention. But in the intervening effect of personality traits between exogenous and endogenous variables, only three personality traits have positive significant mediation—extraversion, conscientiousness, and openness—whereas no mediation was found with neuroticism and agreeableness. Studies have unveiled the fact that there is need to investigate the decisiveness of personality traits for the selection of healthy food (Friedman & Kern, 2014).
