Electronic Alliances: Outsourcing for Competitive Advantage
While several studies have examined the role of strategic alliances in outsourcing, as a way to manage the client-vendor relationship, no systematic attempt has been made to integrate the knowledge from the strategic management literature. The study contributes to this line of research, by developing a framework that weaves the Relational-Theory View with the outsourcing literature. This synthesis leads to the proposition that the more an outsourcing alliance meets the conditions of Relational-Theory, the higher the rent generating potential for the partners. Specific scenarios are generated based on the strategic value of the considered process, as well as the existence and the visibility of the appropriate capability
Top quark longitudinal polarization near the threshold in l+ l- annihilation
We show that the longitudinal polarization of the top quarks produced in the
annihilation of e+ e- or mu+ mu- into tbar t at energies near the threshold is
not affected by the large Coulomb-type corrections, which greatly modify the
total cross section. Thus the longitudinal polarization, although small, may
provide an independent information on the mass and the width of the top quark,
largely independent of the uncertainty in alpha_s.Comment: 6 pages, LaTeX, no figures, added references, corrected typo
DURATION OF COMPETITIVE ADVANTAGE DUE TO EMERGING TECHNOLOGY ADOPTION (22)
The objective of this study is to provide a framework for predicting the expected duration of a competitive advantage due to adoption of an emerging technology, and suggest a process for generating technology specific benchmark of expected duration for the average adopting firm. Our framework integrates elements from the technology adoption (diffusion) cycle, hype cycles of emerging technologies, and the resource based view conceptualization of number of firms associated with a perfectly competitive market equilibrium. The objective of this synthesis is to generate a framework for estimating average technology diffusion time and standard deviation. Given the prevailing assumption that technology diffusion follows an approximate bell shaped distribution, we can use these two values to estimate the duration of a technology adoption related competitive advantage. We demonstrate the empirical estimation of expected duration of competitive advantage for an emerging technology (cloud computing) and a mature one (ERP)
IT Innovation Capability and Returns on IT Innovation Persistence
Prior studies have shown that the IT innovation capability, a company\u27s ability to innovate systematically with IT, is not easily replicated (persistent), and the persistence tends to be more pronounced during periods when economy-wide IT budgets are declining (hard IT budgets), such the post-Y2K period. Building on resource based view we argue that companies that systematically innovate with IT have a sustained competitive advantage versus their competitors who are adopting an opportunistic approach to IT innovation or choose not to innovate with IT, and the advantage is stronger during periods of hard IT budgets. Both of these arguments were strongly supported when tested on a sample of 1,057 large US firms by indicating increased return on sales, return on assets, and growth
CONTRIBUTION AND REWARD OF SENIOR IT EXECUTIVES IN IT CAPABLE FIRMS
The main objective of this study is to propose and test a pattern of positive reciprocity between senior IT executives (sITes) and firms with superior dynamic IT capability (ITC). Results based on panel data of 1326 large US firms from a wide spectrum of industries over a 13 year period (1997-2009) support the following positions: 1. There is a positive association between accrued sources of managerial power of sITes, such as structural and expert power, and a firm\u27s ability to develop superior ITC. 2. Firms that achieve such ITC superiority are more likely to signal their appreciation and reward their sITes with more structural power (a proxy for higher compensation). If sITes value these rewards, they are more likely to stay longer with their firm. 3. There is a positive association between continuity of an already successful IT leadership and a firm’s ability to sustain its ITC superiority (durable ITC heterogeneity), thus setting in motion a virtuous cycle of positive reciprocity between sITes and IT capable firms. These findings have several and significant implications for top management teams, directors, and sITes
Dynamics of an inchworm nano-walker
An inchworm processive mechanism is proposed to explain the motion of dimeric
molecular motors such as kinesin. We present here preliminary results for this
mechanism focusing on observables like mean velocity, coupling ratio and
efficiency versus ATP concentration and the external load F.Comment: 6 pages, 2 figure
Vortex Pull by an External Current
In the context of a dynamical Ginzburg-Landau model it is shown numerically
that under the influence of a homogeneous external current J the vortex drifts
against the current with velocity in agreement to earlier analytical
predictions. In the presence of dissipation the vortex undergoes skew
deflection at an angle with respect to the
external current. It is shown analytically and verified numerically that the
angle and the speed of the vortex are linked through a simple
mathematical relation.Comment: 19 pages, LATEX, 6 Postscript figures included in separate compressed

Sustainable value creation: The role of IT innovation persistence
In this research, we investigate the role of alternative IT innovation strategies (systematic, opportunistic, and non-IT innovation) on earnings persistence. Building on agility theory we argue that systematic IT innovation leads to sustainable value creation and ability to recover from negative earnings and recession. Using a sample of large US firms we find that good (bad) performance of systematic IT innovators is more persistent (transitory) than non-systematic IT innovators, and are more likely to recover from recession. We conclude that systematic IT innovators are better prepared to deal with the modern hypercompetitive environment
