Labor Relations Conflict in the Workplace: Scale Development, Consequences and Solutions

Because the goals of employers and employees are often incompatible, conflicts are inevitable and an essential part of organizational life. The three studies reported in this paper addressed the issues of identifying the dimensions of workplace conflicts within organizations, exploring the consequences of conflicts, and finding appropriate methods of conflict resolution. The first study identified and developed three dimensions of labor relations conflict, including interest-based, rights-based, and emotion-based conflicts. The second study explored two sets of individual outcomes of labor relations conflicts and found labor relations conflicts had a negative effect on employee job satisfaction and affective commitment and positive effects on employee turnover intention and counterproductive work behavior. The third study tested the effectiveness of partnership practices as an alternative method of resolving labor relations conflicts. Suggestions are offered for future research on the labor relations conflict dimensions as well as its outcomes and solutions introduced in these studies

Microscopic and self-consistent description for neutron halo in deformed nuclei

A deformed relativistic Hartree-Bogoliubov theory in continuum has been developed for the study of neutron halos in deformed nuclei and the halo phenomenon in deformed weakly bound nuclei is investigated. Magnesium and neon isotopes are studied and some results are presented for the deformed neutron-rich and weakly bound nuclei 44Mg and 36Ne. The core of the former nucleus is prolate, but the halo has a slightly oblate shape. This indicates a decoupling of the halo orbitals from the deformation of the core. The generic conditions for the existence of halos in deformed nuclei and for the occurrence of this decoupling effect are discussed.Comment: 7 pages, 2 figures; invited talk at the XXXV Brazilian Workshop on Nuclear Physics, Sep 2-6, 2012, Maresias, Brazi

Halos in a deformed Relativistic Hartree-Bogoliubov theory in continuum

In this contribution we present some recent results about neutron halos in deformed nuclei. A deformed relativistic Hartree-Bogoliubov theory in continuum has been developed and the halo phenomenon in deformed weakly bound nuclei is investigated. These weakly bound quantum systems present interesting examples for the study of the interdependence between the deformation of the core and the particles in the halo. Magnesium and neon isotopes are studied and detailed results are presented for the deformed neutron-rich and weakly bound nuclei 42Mg. The core of this nucleus is prolate, but the halo has a slightly oblate shape. This indicates a decoupling of the halo orbitals from the deformation of the core. The generic conditions for the existence of halos in deformed nuclei and for the occurrence of this decoupling effect are discussed.Comment: 6 pages, 2 figures; invited talk at the 2nd Int. Conf. on Nuclear Structure & Dynamics (NSD12), Opatija, Croatia, 9-13 July 201

Density-dependent deformed relativistic Hartree-Bogoliubov theory in continuum

The deformed relativistic Hartree-Bogoliubov theory in continuum with the density-dependent meson-nucleon couplings is developed. The formulism is briefly presented with the emphasis on handling the density-dependent couplings, meson fields, and potentials in axially deformed system with partial wave method. Taking the neutron-rich nucleus $^{38}$Mg as an example, the newly developed code is verified by the spherical relativistic continuum Hartree-Bogoliubov calculations, where only the spherical components of the densities are considered. When the deformation is included self-consistently, it is shown that the spherical components of density-dependent coupling strengths are dominant, while the contributions from low-order deformed components are not negligible.Comment: 5 pages, 3 figures, and 1 tabl

Numerical Simulation of Marina Storage Fires Using Measured Composite Fire and Thermal Properties

Fire test data of boats in rack storage are needed to establish more specific requirements for fire control and protection for this type of vessel in high piled rack storage configurations. Since there is no current large or full scale fire test data available, we have embarked upon testing fire and thermal properties of boat material, fiber reinforced polymer (FRP) composite, by using Differential Scanning Calorimetry, and Cone Calorimeter in order to determine the most effective method to provide sprinkler protection to an indoor boat storage facility. Fire and thermal properties of FRP were obtained from experiments and incorporated into the fire dynamics simulator (FDS) model, to simulate fire growth, fire spread, and the capability of the sprinkler system on fire control in a proposed indoor marina dry boat storage facility in Florida. The simulations indicated that in-rack sprinklers, combined with high water density ceiling sprinkler systems, are important to control fire spread in the storage warehouse. Understanding material properties and incorporating them appropriately into the FDS model could help us better understand fire growth in a marina dry storage facility, and enhance fire safety design

Translation of Solzhenitsyn’s work in the mode of “internal distribution” in China (1960–1980)

In China, the interest to the work of A. I. Solzhenitsyn arose soon after the publication of his story One Day in the Life of Ivan Denisovich in the journal New World with the permission of N. S. Khrushchev in 1962, which immediately attracted the attention of Chinese literary circles. However, the initial interest in Solzhenitsyn was connected with the political situation in China at that time. The period from the 1960s to the 1980s can be considered the initial stage of the translation of the writer’s work. Almost all the works translated during these years were marked by “internal distribution”. The purpose of this paper is to identify the features of the history of translation and publication of A. I. Solzhenitsyn’s work in the “internal distribution” mode with Chinese characteristics. In the course of the research, for the first time, a connection is established between the system of production of printed materials in the 1960–1980s in China and the process of translating the works of the Russian writer, which determines the scientific novelty of this work. The author of the article pays special attention to the analysis of the historical background of the implementation of the “internal distribution” regime in China. The implementation of such a regime in the 1960–1980s was inseparable from the social, political and cultural context of the time. Knowledge of the context and historical background of this phenomenon will help not only to understand the historical conditions for the translation of Solzhenitsyn’s works during this period, but also to clarify the general picture of the acceptance of the writer in China. The study reveals that the label “internal distribution” for a long time influenced the perception of Solzhenitsyn’s work by the Chinese audience, giving rise to a critical, negative attitude towards the writer himself and his works. However, with the disappearance of ideological pressure in the 1990s, a rational study of the work of A.I. Solzhenitsyn begins in the Chinese scientific community and it is evaluated precisely from the point of view of the literary heritage

Fire Behavior of Some Southern California Live Chaparral Fuels

Wildfire spread in living vegetation, such as chaparral in southern California, often causes significant damage to infrastructure and ecosystems. In order to study wildfire spread in living vegetation, four of the most common chaparral in southern California, chamise, manzanita, scrub oak and ceanothus, were burned and compared. The observed fire behavior included mass loss rate, flame height, temperature structure and velocity field above the burning fuel bed. It was observed that flame height increases mainly with heat release rate. By using successive images of the temperature field, a recently developed thermal particle image velocity (TPIV) algorithm was applied to estimate flow velocities in the vicinity of the flame. The results are generally in agreement with other experimental results obtained on gas and liquid fuels

Experimental Investigation of the Velocity Field in Buoyant Diffusion Flames Using PIV and TPIV Algorithm

We investigated a simultaneous temporally and spatially resolved 2-D velocity field above a burning circular pan of alcohol using particle image velocimetry (PIV). The results obtained from PIV were used to assess a thermal particle image velocimetry (TPIV) algorithm previously developed to approximate the velocity field using the temperature field, simultaneously captured by an infrared (IR) thermal camera. By tracing “thermal particles,” which were assumed to be virtual particles that corresponded to pixels of temperature values in successive IR images, the TPIV algorithm estimated a larger scale instantaneous velocity field than either a single-point velocity measurement (e.g., LDV) or the area velocity measurement such as PIV. Instantaneous velocity fields obtained from both methods are presented. Time series vertical velocity profiles and time-averaged velocity vector fields are compared. The comparison demonstrates the applicability and performance of the TPIV algorithm in wildfire research

IR-Based Estimation of Velocities Above Flames Spreading over Different Fuels

Wildfire spread in living vegetation such as chaparral in California and eucalyptus forests in Australia often causes significant damage to infrastructure and ecosystems. A physically based empirical model to predict fire spread rate is used in the United States to assist in a variety of fire management operations. The spread model does not adequately describe the chemical processes of combustion in live fuels. Prior to describing and modeling the chemical processes of combustion in wildland fuels using computational fluid dynamics, we are investigating a technique to non-intrusively measure flame gas velocities using thermal imagery. By tracing hot pixels through successive digital images, we estimate velocity field using gradient-based algorithms. We also explore techniques established in digital particle image velocimetry (DPIV) to estimate fluid velocities. The images are acquired by a thermal camera with uncooled microbolometer 320x240 pixel focal plane array in the 7.5 - 13 um spectral range. We estimated fluid velocities in flames spreading above isopropyl alcohol and shredded aspen wood (excelsior). Results from excelsior fires are presented. Finally, results obtained from computational modeling were used to validate the velocity field estimated from the gradient-based algorithm. Preliminary results using a DPIV-based algorithm appear promising
