Towards a Contingency Resource-Based View of IT Business Value

Empirical research on the business value of IT has often been underpinned by the indispensable tenet of resource complementarity in the resource-based view (RBV) and the crucial concept of fit rooted in contingency theory. Increasingly, it has been recognised that IT needs to be integrated with other organisational factors to create business value. However, empirical studies differ in varying degrees from what organisational factors to be examined and their research findings, but also have been largely biased towards examining pairwise relationships between IT and organisational factors. This paper argues that IT is an integral part of a system of interrelated organisational factors and that a holistic approach is required to further understand when, how and why IT creates business value. After summarising what has been learnt from empirical studies of IT business value, this paper discusses the key conceptual issues of internal fit and resource complementarity as currently conceptualised and employed in the research domain. In order to continue advancing knowledge, this paper argues for and presents a contingency RBV to provide an alternative conceptualisation of IT business value. Essentially, the contingency RBV conjectures that the level of IT business value depends on the interaction of a whole system subject simultaneously to multiple moderators and mediators. Finally, this paper concludes with a discussion of the value of the contingency RBV and its implications for future research.

A two-tier location management mechanism for IMS

This paper proposed a two-tier location management mechanism(TTLM)by improving the currentregistration mechanism(CR)in IP Multimedia Subsystem(IMS).The TTLM includes the visited networkregistration and the home network registration,in which the visited network registration is responsible forre-registration in IMS.When subscriber roams,the location information of home network will be updatedby the visited network based on the change of user equipment(UE)' s IP address.Therefore the TTLMcan reduce the tim...

Redox modulated hydrogelation of a self-assembling short peptide amphiphile

Hydrogels resulting from the self-assembly of small peptides are smart nanobiomaterials as their nanostructuring can be readily tuned by environmental stimuli such as pH,ionic strength and temperature,thereby favoring their practical applications.This work reports experimental observations of formation of peptide hydrogels in response to the redox environment.Ac-I 3 K-NH 2 is a short peptide amphiphile that readily self-assembles into long nanofibers and its gel formation occurs at concentrations of about 10 mmol/L.Introduction of a Cys residue into the hydrophilic region leads to a new molecule,Ac-I 3 CGK-NH 2,that enables the formation of disulfide bonds between self-assembled nanofibers,thus favoring cross-linking and promoting hydrogel formation.Under oxidative environment,Ac-I 3 CGK-NH 2 formed hydrogels at much lower concentrations(even at 0.5 mmol/L).Furthermore,the strength of the hydrogels could be easily tuned by switching between oxidative and reductive conditions and time.However,AFM,TEM,and CD measurements revealed little morphological and structural changes at molecular and nano dimensions,showing no apparent influence arising from the disulfide bond formation.     

个体主义集体主义文化价值理论的细化和发展——以广告研究为例

个体主义集体主义二元文化价值理论已经发展成为垂直性和平行性的个体主义和集体主义的四维体系。本文梳理了该理论的发展,并以广告研究为例,在新的理论框架下,讨论如何预测多种消费行为和消费满意。研究结果表明垂直性和平行性的细分有助于更好地理解个体主义/集体主义理论解释下的已知现象。虽然在起动方法上存在挑战,以等级和地位为动机的文化模式研究在未来势必会成为新的研究热点,丰富跨文化理论的研究内容。
