Rent Appropriation in Strategic Alliances: A Study of Technical Alliances in Pharmaceutical Industry

Many existing alliance studies have investigated how embedded relations create superior value for organizations. The role of network structure in rent appropriation or pie splitting, however, has been underexplored. We propose that favorable locations in interorganizational networks provide firms with superior opportunities for appropriating more economic benefits from alliances than their partners do. Specifically, we argue that partners’ asymmetric network positions will lead to unequal brokerage positions that promote disparate levels of information gathering, monitoring, and bargaining power, which lead to differing capacities to appropriate value. This in turn results in variations in market performance. We also propose this brokerage position exacerbates existing inequalities such as commercial capital; thus, available firm resources will moderate such network effects. Evidence is presented in the form of market response to technology alliance announcements from a set of pharmaceutical firms. In general, we find that firms within central network positions and those spanning structural holes have higher returns than their partners. In addition, we show that this relationship is contingent upon available firm resources

Effect of Aggregation at a Winter Feeding Station on Intestinal Parasite Load in Elk (Cervus canadensis)

Winter feeding stations are used throughout the western US to reduce elk depredation of crops and haystacks on private lands. Many of the unintended effects of such artificial congregation remain unexamined, but generally, across species, locally increased host densities result in increased parasite loads. This adds physiological stress to individual animals and in game species such as elk it could reduce their value to sportsmen. Through laboratory analyses of fresh samples, we recorded nematode egg densities in elk feces collected during two periods ( early and late) in the supplementary feeding season. Mean nematode egg density remained fairly constant in fecal samples over these periods but the proportion of infected elk was significantly higher in the later stage of the feeding season. Results confirm that nematode loads carried by individual elk in this population during the study period were below the level at which clinical symptoms of morbidity would be expected. However, at the population level, the increased prevalence of nematode infection from early to late stages of supplementary feeding implies that the feeding station does facilitate parasite transmission

Organizational speed as a dynamic capability: Toward a holistic perspective

Current research on organizational speed has been disjointed, which has left organizational speed as an underdeveloped area of study. In this essay, we expand the view of organizational speed as a multidimensional gestalt-like construct that may influence firm performance and competitive advantage. We offer a capability-based definition of organizational speed and identify and review the building blocks of organizational speed. We propose new avenues and questions for future research based on our perspective

Practical quantum key distribution over a 48-km optical fiber network

The secure distribution of the secret random bit sequences known as "key" material, is an essential precursor to their use for the encryption and decryption of confidential communications. Quantum cryptography is a new technique for secure key distribution with single-photon transmissions: Heisenberg's uncertainty principle ensures that an adversary can neither successfully tap the key transmissions, nor evade detection (eavesdropping raises the key error rate above a threshold value). We have developed experimental quantum cryptography systems based on the transmission of non-orthogonal photon states to generate shared key material over multi-kilometer optical fiber paths and over line-of-sight links. In both cases, key material is built up using the transmission of a single-photon per bit of an initial secret random sequence. A quantum-mechanically random subset of this sequence is identified, becoming the key material after a data reconciliation stage with the sender. Here we report the most recent results of our optical fiber experiment in which we have performed quantum key distribution over a 48-km optical fiber network at Los Alamos using photon interference states with the B92 and BB84 quantum key distribution protocols.Comment: 13 pages, 7 figures, .pdf format submitted to Journal of Modern Optic

Evaluation of the Coventry and Warwickshire Connexions Service 2000-2001.‌

This report was commissioned by the Coventry and Warwickshire Connexions Strategic Partnership to help identify the overall effectiveness of the local Connexions pilot project. The Coventry and Warwickshire sub-region is one of 16 pilot areas for the new Connexions service. The pilot is designed to trial new ways of working in local communities and focuses on the work of Personal Advisers (PAs) in educational institutions and in community settings with partner organisations. Within this context, research and evaluation play a crucial role in helping to assess the impact of the Connexions Strategy on the local community and in supporting policy-makers and practitioners to determine what works and why. From 1st April 2001, Coventry and Warwickshire will receive further Government funding to deliver the new Connexions Service as part of the national roll-out programme in England

Measurement of bacterial flagellar thrust by negative dielectrophoresis

The force produced by the flagella of the bacterium Salmonella typhimurium has been measured using negative dielectrophoretic methods. The bacteria are held in a force funnel, produced using a nonuniform electric field. When the motor force is balanced against an opposing negative dielectrophoretic force the bacteria become motionless. Numerical simulations have been used to estimate the electric field gradient in the electrodes. Together with experimental observations of bacterial motion the data gives a value of the force produced by the bacterial motor to be 0.37 pN

Rivals’ Reactions to Mergers and Acquisitions

Mergers and acquisitions research has principally focused on attributes of the acquiring firm and post-acquisition outcomes. To extend our knowledge, we focus on external factors, in particular rival responses, and explore when and how rivals respond to their competitor’s acquisitions. Leveraging the awareness–motivation–capability framework, we predict and find evidence that a rival’s dependence on markets in common with the acquirer, resource similarity between rival and acquirer, and a rival’s organizational slack increase the volume and, in some cases, also the complexity of a rival’s competitive actions following an acquisition. Furthermore, the type of acquisition positively moderates some of these relationships. The results extend our understanding of the influence of mergers and acquisitions on competitive dynamics in the marketplace

Exploitative learning and entrepreneurial orientation alignment in emerging young firms: implications for market and response performance

We examine exploitative learning and entrepreneurial orientation (EO) in emerging young high technology firms located within business incubators. In the last five years, the UK government has invested approximately £125m in incubation activities. The rationale for supporting business incubation is to maximize knowledge sharing across firms with an expectation that it will leverage performance. This represents exploitative learning – the acquisition of established knowledge that carries clear known value and outcomes. Paradoxically, research into EO has repeatedly emphasized the value of knowledge created through exploratory learning mechanisms (‘play, discovery and experimentation’) in securing advantage. Theoretical and empirical questions are raised herein with regard to the value of exploitative learning within a network context which might negatively influence the impact of EO on the firm. Using configuration theory, we demonstrate that firms cannot sustain dual-dominant orientations of exploitative learning and EO. A strongly configured EO generates high performance returns. However, multi-group analysis reveals that these effects are particularly strong for those firms whose exploitative learning is weak. Implications and directions for future research are discussed
