Structures that Work: Social Structure, Work Structure and Coordination Ease in Geographically Distributed Teams
Social Structure Work Structure
2015/7/3
Scholars have recently argued for flatter, organic organizational
structures that enable workers to deal more effectively with
dynamic and uncertain environments. In a correlational study of
33 ...
Skilled Immigration and the Employment Structures of U.S. Firms
Firms Scientists Engineers Inventors H-1B Age Employment Immigration United States
2015/5/14
We study the impact of skilled immigrants on the employment structures of U.S. firms using matched employer-employee data. Unlike most previous work, we use the firm as the lens of analysis to account...
Team Scaffolds:How Meso-Level Structures Support Role-based Coordination in Temporary Groups
Fluid Personnel Team Scaffolds Team Effectiveness Role-Based Coordination Multi-Method
2015/4/27
This paper shows how meso-level structures support effective coordination in temporary groups. Prior research on coordination in temporary groups describes how roles encode individual responsibilities...
High-order-mode soliton structures in two-dimensional lattices with defocusing nonlinearity
Discrete soliton self-focusing defocusing nonlinear dipole the structure of vortex solitons
2014/12/25
While fundamental-mode discrete solitons have been demonstrated with both self-focusing and defocusing nonlinearity, high-order-mode localized states in waveguide lattices have been studied thus far o...
X, Y, and Z waves: Extended structures in nonlinear lattices
Waveform the two-dimensional nonlinear structure lattice soliton condensate
2014/12/25
We propose a new type of waveforms in two-dimensional (2D) and three-dimensional (3D) discrete media-multilegged extended nonlinear structures (ENSs), built as arrays of lattice solitons (tiles and st...
Smooth and symplectic symmetries of an infinite family of distinct exotic K3 surfaces are studied, and a comparison with the corresponding symmetries of the standard K3 is made. The action on the K3 l...
Vortex structures formed by the interference of sliced condensates
Vortex and vortex ring structure condensate
2014/12/24
We study the formation of vortices, vortex necklaces, and vortex ring structures as a result of the interference of higher-dimensional Bose-Einstein condensates (BECs). This study is motivated by earl...
Localized structures in kagome lattices
Kagome whirlpool stable soliton lattice defocusing nonlinear discrete continuum model
2014/12/24
We investigate the existence and stability of gap vortices and multipole gap solitons in a kagome lattice with a defocusing nonlinearity both in a discrete case and in a continuum one with periodic ex...
Short pulse equations and localized structures in frequency band gaps of nonlinear metamaterials
Short pulse propagation nonlinear metamaterials nonlinear dielectric short pulse linear electromagnetic waves magnetic permeability
2014/12/24
We consider short pulse propagation in nonlinear metamaterials characterized by a weak Kerr-type nonlinearity in their dielectric response. Two short-pulse equations (SPEs) are derived for the high- a...
Stable structures with high topological charge in nonlinear photonic quasicrystals
Whirlpool analysis of photonic crystals nonlinear
2014/12/24
Stable vortices with topological charges of 3 and 4 are examined numerically and analytically in photonic quasicrystals created by interference of five as well as eight beams, for cubic as well as sat...
Stable Vortex–Bright-Soliton Structures in Two-Component Bose-Einstein Condensates
Numerical two-component structure condensate ordinary topological charge symbiotic state defocusing eddy
2014/12/24
We report the numerical realization of robust two-component structures in 2D and 3D Bose-Einstein condensates with nontrivial topological charge in one component. We identify a stable symbiotic state ...
Simultaneous Model Selection and Estimation for Mean and Association Structures with Clustered Binary Data
association clustered binary data generalized estimating equation logistic regression variable selection
2012/9/17
This paper investigates the property of the penalized estimating equations when both the mean and association structures are modelled. To select variables for the mean and association structures seque...
The use of systems of stochastic PDEs as priors for multivariate models with discrete structures
Gaussian distribution multivariate stochastic PDEs discrete structures
2012/9/17
A challenge in multivariate problems with discrete structures is the inclusion of prior information that may di er in each separate structure. A particular example of this is seismic amplitude versus ...
Revealing spatial variability structures of geostatistical functional data via Dynamic Clustering
functional data clustering geostatistics variogram
2011/7/6
In several environmental applications data are functions of time, essentially con- tinuous, observed and recorded discretely, and spatially correlated. Most of the methods for analyzing such data are ...
The Stakeholder Model: The Influence of the Ownership and Governance Structures
governance structure ownership structure property rights and decision rights stakeholders
2010/11/5
This paper addresses the possibilities to introduce the stakeholder model in the firm, especially the possibility to give property or decision rights to stakeholders. This paper argues that it is not ...
