Purpose: The purpose of this paper is to examine the mediating roles of two variables of psychological empowerment and affective commitment of frontline service employees (FSEs) in the relationship between transformational leadership (TFL) and proactive customer service behavior (PCSB) of FSEs. Design/methodology/approach: In a rigorous research design, the authors obtained data from 225 FSE-supervisor dyads working in a large Indian IT services organization. Analysis was done using structural equation modeling approach in LISREL 8.72. Findings: As expected, affective commitment and psychological empowerment of FSEs fully mediated the positive relationship between TFL and PCSB of FSEs, even after controlling for age and tenure. The specified model explained 24 percent of the variance in PCSB of FSEs. Research limitations/implications: As FSEs act as the face of a service organization, therefore their proactive behavior plays an important role in customer satisfaction. Enactment of TFL by supervisors fosters PCSB of FSEs. Therefore, organizations must develop TFL skills in their managers to psychologically empower FSEs and get them committed to a superior service delivery through PCSB. Originality/value: The study is one amongst the few studies to explore the relationship between TFL and proactive behavior in the customer service domain. Additionally, to the best of the authors’ knowledge, this is the first study to examine the explanatory mechanisms through which transformational leaders foster PCSB of FSEs. © 2017, © Emerald Publishing Limited.

Project management as a discipline possesses a rich body of literature characterized by early determinism and later expansion to broader contexts aided by paradigmatic, thematic, and methodological diversity. The dynamic nature of research entails many parallel streams of enquiry under differing perspectives without convergence to parsimonious theories. We argue that an integrated view of project management research in terms of its thematic evolution and trends is necessary for an understanding of future directions. Our study fills this gap by tracing the evolution of themes in project management research, trends, and future opportunities through a systematic review of literature. We find the research to be dominated by empirical and deterministic perspectives while non-deterministic research enquiry remains weak and sporadic. We contend that stronger focus on non-deterministic perspective and a methodological convergence is necessary for the research to meaningfully advance towards theory building, and discuss potential avenues for further research. © 2016 Elsevier Ltd and Association for Project Management and the International Project Management Association

Purpose: This paper aims to present a review of literature to assess the progress of research on managerial issues in the pharmaceutical industry globally. Design/methodology/approach: Literature from peer-reviewed journals available on online databases was collected for the last decade, using the keyword search technique, and then classifying it according to major managerial issues, research methodologies used and geographical zones. Findings: Behavioral issues at the consumer/physician level and non-behavioral issues in pricing and medical expenses are studied the most, followed by supply chain management, research and development and manufacturing and services operations management. There is scope for conjunction of research efforts across themes and players. The studies focus on the developed nations through the application of field research and mathematical modeling techniques. The studies in the American region focus more on development and marketing while studies in Europe are aligned towards manufacturing and distribution in the industry. Studies in the developing nations are mostly exploratory in nature and require more focus on issues of research and development and marketing in addition to a substantial increase in overall research efforts. More trans-continental studies are needed to consolidate research efforts globally. Research limitations/implications: The review is not exhaustive of all studies available on the industry and each of the issues. Conference papers, unpublished material and lectures were excluded. Practical implications: Identification of the present and emerging issues together provides practitioners in healthcare systems with an idea of available techniques and strategies to solve problems in healthcare/pharmaceutical management. Originality/value: A study on research of management issues in the pharmaceutical industry across the world has perhaps not been conducted in the recent past: this paper fills part of that gap. © Emerald Group Publishing Limited.

A single distribution-free (nonparametric) Shewhart-type chart on the basis of the Lepage statistic is well known in literature for simultaneously monitoring both the location and the scale parameters of a continuous distribution when both of these parameters are unknown. In the present work, we consider a single distribution-free cumulative sum chart, on the basis of the Lepage statistic, referred to as the cumulative sum-Lepage (CL) chart. The proposed chart is distribution-free (nonparametric), and therefore, the in-control properties of the chart remain invariant and known for all continuous distributions. Control limits are tabulated for implementation of the proposed chart in practice. The in-control and out-of-control performance properties of the cumulative sum-Lepage (CL) chart are investigated through simulation studies in terms of the average, the standard deviation, the median, and some percentiles of the run length distribution. Detailed comparison with a competing Shewhart-type chart is presented. Several existing cumulative sum charts are also considered in the performance comparison. The proposed CL chart is found to perform very well in the location-scale models. We also examine the effect of the choice of the reference value (k) on the performance of the CL chart. The proposed chart is illustrated with a real data set. Summary and conclusions are presented. Copyright © 2014 John Wiley & Sons, Ltd.

This article presents frequentist inference of accelerated life test data of series systems with independent log-normal component lifetimes. The means of the component log-lifetimes are assumed to depend on the stress variables through a linear stress translation function that can accommodate the standard stress translation functions in the literature. An expectation-maximization algorithm is developed to obtain the maximum likelihood estimates of model parameters. The maximum likelihood estimates are then further refined by bootstrap, which is also used to infer about the component and system reliability metrics at usage stresses. The developed methodology is illustrated by analyzing a real as well as a simulated dataset. A simulation study is also carried out to judge the effectiveness of the bootstrap. It is found that in this model, application of bootstrap results in significant improvement over the simple maximum likelihood estimates. © IMechE 2015.

The WiMAX IEEE 802.16 (e) is defined as the Worldwide Interoperability for Microwave Access by the WiMAX Forum, formed in April 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as WirelessMAN. The absence of physical boundaries makes in general a wireless network more vulnerable than a wired network. The IEEE 802.16 provides a security sublayer in the MAC layer to address the privacy issues across the fixed BWA (Broadband Wireless Access). Several proposals have been published to address the flaws in IEEE802.16 security after the release of IEEE802.16-2001. However, even with the modified version IEEE802.16-2004, the security problems still persist and many additional flaws have emerged. This paper examines the threats against the authentication protocols of WiMAX and proposes a new authentication protocol which is more reliable and secure. The proposed protocol is rigid against the attacks like Denial of service (DOS), Man-in-the-middle and replay. © 2010 IEEE.

One of the proposed strategies for implementation of reducing emissions from deforestation and forest degradation plus (REDD+) is to incentivize conservation of forests managed by communities under decentralized forest management. Yet, we argue that this is a challenging road to REDD+ because of three general characteristics of forests under existing decentralized management regimes. First, these forests already accumulate biomass and, in some cases, generate leakage, which threatens to undercut REDD+ additionality. Second, these forests are many and small, which will drive up REDD+ transactions costs. Third, beyond the "conservation islands" represented by forests under decentralized management, processes of deforestation and forest degradation continue. Given these challenges, we argue that REDD+ efforts through decentralized forestry should be redirected from incentivizing further conservation of forests under existing decentralized management arrangements toward a push for extending the coverage of forests under decentralized management, making forest rights the hard currency of REDD+. © 2013 Wiley Periodicals, Inc.

Purpose: The aim of this paper is to present ex-post and ex-ante analysis of the outcomes of ICT adoption in six food processing SMEs based on needs analyses conducted through business diagnostics. Design/methodology/approach: Six food processing SMEs were selected and subsidized to introduce ICT on condition that the SMEs agree to conduct business diagnostics to identify ICT needs, adopt ICT capabilities recommended, agree to outcomes being monitored and the findings being published. Findings: Two amongst the six rigorously selected SMEs did not complete the project citing resource constraints, reveals constraints experienced by SMEs in adopting "new" technology. Four SMEs that completed the project achieved increased operating efficiency or business growth, demonstrating the benefits of ICT adoption. The study concludes that rigorous business analysis is an important precursor to ICT adoption initiatives and SME resource constraints in such initiatives can be successfully overcome through enterprise-government-university partnerships. Research limitations/implications: A longitudinal study, a larger sample size and quantitative data gathering would embellish the findings. Practical implications: ICT adoption is a cost-efficient strategy to facilitate business growth and profitability in SMEs. Because many SMEs may not have appropriate technical and managerial capabilities, enterprise-government-university partnerships are a useful model to undertake such initiatives. Knowledge and methodology from this study could inform public policy action to encourage "new" technology adoption by SMEs. Originality/value: The paper presents a project completed through intervention methodology (selectively recruiting SMEs, diagnosing business and strategic intents, identifying ICT capabilities needs, assisting SMEs adopt customized ICT capabilities) and tracking the outcomes © Emerald Group Publishing Limited.

Routing traffic across a capacitated hub-and-spoke network is very common in freight transportation and telecommunications. Most of the hub-and-spoke network models available in the literature assume a fully inter-connected hub network and allow traffic to pass through a maximum of two hubs. In the absence of a fully inter-connected hub network, the traffic may have to be routed through more than two hubs. In this paper, we develop a mathematical model and a simulated annealing (SA)-based solution methodology for routing freight through not more than three hubs in a given capacitated network. We generate test problem instances to evaluate the efficacy of the mathematical model and the meta-heuristic procedure. The effect of each network parameter on the performance of the SA procedure is analysed thoroughly with extensive computational experiments and relevant statistical tests. The results show that near-optimal solutions for large problem instances can be derived in little computational time. Copyright © 2013 Inderscience Enterprises Ltd.
