Customization Or Conformity? An Institutional And Network Perspective On The Content And Consequences Of TQM Adoption

This study develops a theoretical framework that integrates institutional and network perspectives on the form and consequences of administrative innovations. Hypotheses are tested with survey and archival data on the implementation of total quality management (TQM) programs and the consequences for organizational efficiency and legitimacy in a sample of over 2,700 U.S. hospitals. The results show that early adopters customize TOM practices for efficiency gains, while later adopters gain legitimacy from adopting the normative form of TQM programs. The findings suggest that institutional factors moderate the role of network membership in affecting the form of administrative innovations adopted and provide strong evidence for the importance of institutional factors in determining how innovations are defined and implemented. We discuss implications for theory and research on institutional processes and network effects and for the literatures on innovation adoption and total quality management.(.)Business Administratio

Cooperative Or Controlling? The Effects Of Ceo-Board Relations And The Content Of Interlocks On The Formation Of Joint Ventures

This study examines the influence of the social network of board interlocks on strategic alliance formation. Our theoretical framework suggests how board interlock ties to other firms can increase or decrease the likelihood of alliance formation, depending on the content of relationships between CEOs (chief executive officers) and outside directors. Results suggest that CEO-board relationships characterized by independent board control reduce the likelihood of alliance formation by prompting distrust between corporate leaders, while CEO-board cooperation in strategic decision making appears to promote alliance formation by enhancing trust. The findings also show how the effects of direct interlock ties are amplified further by third-party network ties.Business Administratio

The Market Reaction to Legal Shocks and Their Antidotes: Lessons from the Sovereign Debt Market

In October 2000 a hedge fund holding an unpaid debt claim won an enormous victory against the debtor, the Republic of Peru, through an opportunistic interpretation of the common pari passu clause by a Brussels court. This development was met by charges from policy makers and practitioners that the court\u27s decision (its novel interpretation of the pari passu clause) would lead to a dramatic increase in the risks of holdout litigation faced by sovereign debtors. Over the ensuing years, multiple reform solutions were proposed including the revision of certain contractual terms, the filing of amicus briefs in a key case, and the imposition of an international bankruptcy regime for sovereigns. The question, looking back, that this Article empirically investigates is whether the capital markets actually perceived a significant increase in risk at the time of the October 2000 Brussels court decision. Equally important is whether markets discriminate among competing versions of the pari passu clause based on their relative risks for holdouts. And, to the extent the markets did react to the increase in legal risk, did any of the antidotes that were implemented to reduce the supposed increased holdout risk work? We offer evidence that bond prices did respond to this legal shock, that markets do discriminate based on the relative holdout risk posed by differing forms of the pari passu clause, and provide surprising evidence regarding the efficacy of the government-sponsored antidote, the advent of collective action clauses

The market reaction to legal shocks and their antidotes : lessons from the sovereign debt market

This Article examines the market reaction to a series of legal events concerning the judicial interpretation of the pari passu clause in sovereign debt instruments. More generally, the Article provides insights into the reactions of investors (predominantly financial institutions), issuers (sovereigns), and those who draft bond covenants (lawyers), to unanticipated changes in the judicial interpretation of certain covenant terms

Vehicle infrastructure cooperative localization using Factor Graphs

Highly assisted and Autonomous Driving is dependent on the accurate localization of both the vehicle and other targets within the environment. With increasing traffic on roads and wider proliferation of low cost sensors, a vehicle-infrastructure cooperative localization scenario can provide improved performance over traditional mono-platform localization. The paper highlights the various challenges in the process and proposes a solution based on Factor Graphs which utilizes the concept of topology of vehicles. A Factor Graph represents probabilistic graphical model as a bipartite graph. It is used to add the inter-vehicle distance as constraints while localizing the vehicle. The proposed solution is easily scalable for many vehicles without increasing the execution complexity. Finally simulation indicates that incorporating the topology information as a state estimate can improve performance over the traditional Kalman Filter approac

Study on the morphometric and meristic characteristics of splendid silver belly Leiognathus splendens (Cuvier) from Bombay coast

Ten morphometric and six meristic characters of Leiognathus splendens (Cuvier) of Bombay Coast have been studied sexwise. Regression and sexwise difference if any between the compared morphometric characteristics have been worked out. Range, mode, standard deviation, co-efficient of variation of 6 meristic characters have been analysed. There was no significant difference between the sexes in morphometric and any deviation in the meristic characters

Stock assessment of soldier catfish Osteogeneiosus militaris along the northwest coast of India

Value of length growth parameters L∞, K and t(sub)0 from age-length relation obtained from length-frequency analysis for the soldier catfish stock were estimated to be 47.6 cm, 0.51 per year and 0.03 year respectively. The age at recruitment (t [sub]r) was 0.58 year and the age at first capture (t[sub]c) 0.83 year. The total mortality (Z) was 0.88 including the present natural mortality (M) of 0.84 and fishing mortality (F) of 0.04. The total stock of this fish along the Northwest coast of India was assessed to be 32,413 tons and the MSY 5,426 tons which is much higher than the current catch of 863.8 tons. The potential yield (P[sub]y) of 38.7 g per recruit could be obtained at the optimum of exploitation (t[sub]y) of 2.84 years

Correlations of record events as a test for heavy-tailed distributions

A record is an entry in a time series that is larger or smaller than all previous entries. If the time series consists of independent, identically distributed random variables with a superimposed linear trend, record events are positively (negatively) correlated when the tail of the distribution is heavier (lighter) than exponential. Here we use these correlations to detect heavy-tailed behavior in small sets of independent random variables. The method consists of converting random subsets of the data into time series with a tunable linear drift and computing the resulting record correlations.Comment: Revised version, to appear in Physical Review Letter

When Do People Trust Their Social Groups?

Trust facilitates cooperation and supports positive outcomes in social groups, including member satisfaction, information sharing, and task performance. Extensive prior research has examined individuals' general propensity to trust, as well as the factors that contribute to their trust in specific groups. Here, we build on past work to present a comprehensive framework for predicting trust in groups. By surveying 6,383 Facebook Groups users about their trust attitudes and examining aggregated behavioral and demographic data for these individuals, we show that (1) an individual's propensity to trust is associated with how they trust their groups, (2) smaller, closed, older, more exclusive, or more homogeneous groups are trusted more, and (3) a group's overall friendship-network structure and an individual's position within that structure can also predict trust. Last, we demonstrate how group trust predicts outcomes at both individual and group level such as the formation of new friendship ties.Comment: CHI 201

Methodology for the effective stabilization of tin-oxide-based oxidation/reduction catalysts

The invention described herein involves a novel approach to the production of oxidation/reduction catalytic systems. The present invention serves to stabilize the tin oxide reducible metal-oxide coating by co-incorporating at least another metal-oxide species, such as zirconium. In one embodiment, a third metal-oxide species is incorporated, selected from the group consisting of cerium, lanthanum, hafnium, and ruthenium. The incorporation of the additional metal oxide components serves to stabilize the active tin-oxide layer in the catalytic process during high-temperature operation in a reducing environment (e.g., automobile exhaust). Moreover, the additional metal oxides are active components due to their oxygen-retention capabilities. Together, these features provide a mechanism to extend the range of operation of the tin-oxide-based catalyst system for automotive applications, while maintaining the existing advantages
