Determining the optimum number of suppliers and the optimum quantities to order from each of them is a critical problem for any supply chain. This paper has mathematically arrived at conditions to identify the appropriate sourcing strategy in a multi-period scenario for a stochastic supply and a stochastic demand environment. It has also obtained the total order quantity, optimum number of suppliers and order allocation to each of the suppliers under both uncertain demand and supply in the multiple-period context. Through a numerical analysis this work could bring interesting managerial insights about the sourcing strategies. Copyright © 2014, IGI Global.

Supply chain innovation has become all the more important in today's competitive world. Supply chain innovation is the development of newer technologies and procedures along with implementation of new ideas of products and services through necessary supply chain activities. As supply chains are network of inter-connected firms; hence the importance of relational and social exchange attributes like trust, commitment, reciprocity and power are paramount in developing supply chain capabilities. The current investigation adopts a social exchange perspective and investigates the importance of trust, commitment, reciprocity and power on integration of logistics capabilities and their subsequent role in developing supply chain innovation. As supply chain innovation aims to provide better performance implications for the focal firm; the impact of supply chain innovation on firm performance was also explored using a service perspective. Data collected through a web-based survey from 173 logistics and supply chain professionals largely support the proposed relationships. Copyright © 2016, IGI Global.

This paper deals with the analysis of the volatility persistence and the leverage effect across six non-ferrous metals spot and futures series in India. Data for aluminium, copper, lead, nickel, zinc and tin were collected from 1st January, 2009 to 30th June, 2012. Volatility persistence was determined throughout the ARCH/GARCH class of models. The leverage effect was tested using TARCH and EGARCH models. Out of the twelve non-ferrous metals series including both spot and futures, TGARCH captures asymmetric effects in seven series and EGARCH captures leverage effect in ten series. Other long memory features of the data were also examined. Testing fractional integration our results show that the series are I(1) but the squared returns display long memory features. © 2014 Elsevier Ltd.

The purpose of this paper is to comprehend the causes and outcome of smart phone application prominence and self-connection. This study conceptualizes self connection and prominence with smart phone application as app self connection and app prominence/app self prominence from brand attachment perspective and identifies app usage frequency as their outcome. On the theoretical front, this paper conceived app self connection and app prominence/app self prominence as a construct that helps in explaining patronage behavior of app amongst targeted consumers. On the managerial front, this paper explicates various strategies that a manager should adopt to improve app usage frequency amongst its targeted users. © Research India Publications.

Extant literature on recruitment has focused on the traditional sources of recruitment like company brochures, career fairs, and impact of such sources on intent to join the organization, productivity and turnover intention. The influence of recruitment related information on pre hire outcomes is still scarce and inconclusive. With the advent of technology and access to Internet, company websites have become an important source of recruitment. Apart from company websites, job seekers are now using company independent websites, forums or online communities to gather a more truthful picture and information about the job and organizational attributes. Social media too has become increasingly important medium where the current employees’ share how it is to work with the organization However research on web based recruitment is limited to company websites. Despite the widespread growth and practical use of these new and innovative media very little is known about how these independent sites influence recruitment pre hire outcomes. In this direction the proposed study presents a conceptual framework about how job seekers perceive company independent websites as a tool for providing recruitment communication and their impact on organizational attractiveness using Information Realism, Person-Environment fit framework, Source Credibility framework. © 2014 The Authors.
