Relationship-Based Approach to Leadership: Development of Leader-Member Exchange (LMX) Theory of Leadership over 25 Years: Applying a Multi-Level Multi-Domain Perspective

Research into Leader-Member Exchange (LMX) theory has been gaining momentum in recent years, with a multitude of studies investigating many aspects of LMX in organizations. Theoretical development in this area also has undergone many refinements, and...

Information Systems Success: The Quest for the Dependent Variable

A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success. However, the dependent variable in these studies—I/S success—has been an elusive one...

Cloud computing and emerging IT platforms: Vision, hype, and reality for delivering computing as the 5th utility

With the significant advances in Information and Communications Technology (ICT) over the last half century, there is an increasingly perceived vision that computing will one day be the 5th utility (after water, electricity, gas, and telephony). This...

Oxygen isotope and palaeomagnetic stratigraphy of Equatorial Pacific core V28-238: Oxygen isotope temperatures and ice volumes on a 105 year and 106 year scale ☆

Core Vema 28-238 preserves an excellent oxygen isotope and magnetic stratigraphy and is shown to contain undisturbed sediments deposited continuously through the past 870,000 yr. Detailed correlation with sequences described by Emiliani in the Caribbean...

Integrins and signal transduction pathways: the road taken

Adhesive interactions play critical roles in directing the migration, proliferation, and differentiation of cells; aberrations in such interactions can lead to pathological disorders. These adhesive interactions, mediated by cell surface receptors that...

Phase Annealing in SHELX-90: Direct Methods for Larger Structures

A number of extensions to the multisolution approach to the crystallographic phase problem are discussed in which the negative quartet relations play an important role. A phase annealing method, related to the simulated annealing approach in other optimization...

The Separation of Ownership and Control in East Asian Corporations

We examine the separation of ownership and control for 2,980 corporations in nine East Asian countries. In all countries, voting rights frequently exceed cash-flow rights via pyramid structures and cross-holdings. The separation of ownership and control...

Specificity of receptor tyrosine kinase signaling: Transient versus sustained extracellular signal-regulated kinase activation

A number of different intracellular signaling pathways have been shown to be activated by receptor tyrosine kinases. These activation events include the phosphoinositide 3-kinase, 70 kDa S6 kinase, mitogen-activated protein kinase (MAPK), phospholipase...

Economic Action and Social Structure: The Problem of Embeddedness

How behavior and institutions are affected by social relations is one of the classic questions of social theory. This paper concerns the extent to which economic action is embedded in structures of social relations, in modern industrial society. Although...

Mean shift: a robust approach toward feature space analysis

A general non-parametric technique is proposed for the analysis of a complex multimodal feature space and to delineate arbitrarily shaped clusters in it. The basic computational module of the technique is an old pattern recognition procedure: the mean...

Compact heat exchangers

Consumer Trust, Value, and Loyalty in Relational Exchanges

The authors develop a framework for understanding the behaviors and practices of service providers that build or deplete consumer trust and the mechanisms that convert consumer trust into value and loyalty in relational exchanges. The proposed framework...

Methods in Computational Physics

Berni J. Alder, Sidney Fernbach, Manuel Rotenberg

Increasing Returns and Economic Geography

This paper develops a two-region, two-sector general equilibriun model of location. The location of agricultural production is fixed, but ionopolistcally competitive manufacturing finns choose their location to maximize profits. If transportation costs...

Dynamics of the dissipative two-state system

Anthony J. Leggett, Sreejit Chakravarty, A. T. Dorsey, Matthew Fisher, Anupam Garg, Wilhelm Zwerger

A gene encoding an antigen recognized by cytolytic T lymphocytes on a human melanoma

Many human melanoma tumors express antigens that are recognized in vitro by cytolytic T lymphocytes (CTLs) derived from the tumor-bearing patient. A gene was identified that directed the expression of antigen MZ2-E on a human melanoma cell line. This...

Human Agency in Social Cognitive Theory

The present article examines the nature and function of human agency within the conceptual model of triadic reciprocal causation. In analyzing the operation of human agency in this interactional causal structure, social cognitive theory accords a central...

The Separation of Ownership and Control in East Asian Corporations

We examine the separation of ownership and control for 2,980 corporations in nine East Asian countries. In all countries, voting rights frequently exceed cash-flow rights via pyramid structures and cross-holdings. The separation of ownership and control...

Mobility increases the capacity of ad-hoc wireless networks

The capacity of ad-hoc wireless networks is constrained by the mutual interference of concurrent transmissions between nodes. We study a model of an ad-hoc network where n nodes communicate in random source-destination pairs. These nodes are assumed to...

Intraspecific Phylogeography: The Mitochondrial DNA Bridge Between Population Genetics and Systematics

John C. Avise, Jonathan Arnold, R. M. Ball, Eldredge Bermingham, A Reeb, Nancy C. Saunders

Marker tracking and HMD calibration for a video-based augmented reality conferencing system

We describe an augmented reality conferencing system which uses the overlay of virtual images on the real world. Remote collaborators are represented on virtual monitors which can be freely positioned about a user in space. Users can collaboratively view...

The structure of the potassium channel: molecular basis of K+ conduction and selectivity.

The potassium channel from Streptomyces lividans is an integral membrane protein with sequence similarity to all known K+ channels, particularly in the pore region. X-ray analysis with data to 3.2 angstroms reveals that four identical subunits create...

Principles and Practices of Interconnection Networks

One of the greatest challenges faced by designers of digital systems is optimizing the communication and interconnection between system components. Interconnection networks offer an attractive and economical solution to this communication crisis and are...

Solid Phase Peptide Synthesis

The last two decades have been an era of rapid progress in peptide research. This era was begun by the work of Sanger on the amino acid sequence determination of insulin and by du Vigneaud on the structure determination and synthesis of oxytocin. This...

Agency Problems and the Theory of the Firm

This paper attempts to explain how the separation of security ownership and control, typical of large corporations, can be an efficient form of economic organization. We first set aside the presumption that a corporation has owners in any meaningful sense....

The Neural Basis of Human Error Processing: Reinforcement Learning, Dopamine, and the Error-Related Negativity

The authors present a unified account of 2 neural systems concerned with the development and expression of adaptive behaviors: a mesencephalic dopamine system for reinforcement learning and a “generic” error-processing system associated with the anterior...

Spectrophotometric assay and properties of the angiotensin-converting enzyme of rabbit lung

A sensitive, fixed-time, spectrophotometric assay for angiotensin-converting enzyme measures the rate of production of hippuric acid from hippuryl-L-histidyl-L-leucine (HHL). The angiotensin-converting enzyme from rabbit lung acetone powder extract, when...

Cetuximab monotherapy and cetuximab plus irinotecan in irinotecan-refractory metastatic colorectal cancer

background The epidermal growth factor receptor (EGFR), which participates in signaling pathways that are deregulated in cancer cells, commonly appears on colorectal-cancer cells. Cetuximab is a monoclonal antibody that specifically blocks the EGFR. We...

On the Determination of the Public Debt

A public debt theory is constructed in which the Ricardian invariance theorem is valid as a first-order proposition but where the dependence of excess burden on the timing of taxation implies an optimal time path of debt issue. A central proposition is...
