Good to be Disliked? Exploring the Relationship Between Disapproval of Organizations and Job Satisfaction in the French context.

Previous research has found that a positive relationship exists between favourable perception of a firm and employees’ job satisfaction: the more positively an organization is perceived, the happier are its workers. However, the current literature has overlooked the consequences of a negative corporate image or disapproval of organizations. Building on the concept of organizational identification and the social identity literature, we fill in this gap and counterintuitively argue that employees are more likely to identify and align with their organizations when it faces illegitimate criticism. We test our hypotheses on a large-scale survey collected in France and find that perception of disapproval of an organization has indeed an adverse effect on job satisfaction. However, if employees perceive criticism as illegitimate, job satisfaction is positively impacted. This study suggests the existence of micro-level social identity reactions in case of unjustified disapprobation: employees stick together and hold the line against criticism, strengthening the collective identity and adding positive emotional value to the work experience.</jats:p

Blame Game Theory: Scapegoating, Whistleblowing and Discursive Struggles following Accusations of Organizational Misconduct

Research on organizational misconduct has examined how audiences generate discourses to make sense of behaviour that may transgress the line between right and wrong. However, when organizations are accused of misconduct, the resulting ambiguity also opens opportunities for organizations and their members to generate discourses aimed at deflecting blame. Little is known about how actors who are at risk of being held responsible actively respond to misconduct accusations by engaging in discursive strategies. To address this question, we build on crisis communication and discourse theory to integrate processes of scapegoating and whistleblowing into a holistic model. We develop a blame game theory – conceptualizing the sequence of discursive strategies employed by an organization and its members to strategically shift blame by attributing responsibility to others or denying misconduct. Our model identifies four blame game pathways as a function of two types of ambiguity: moral ambiguity and attributional ambiguity. We highlight accusations of misconduct as pivotal triggering events in the social construction of misconduct. By conceptualizing the discursive dynamics of strategic reactions to accusations of misconduct, our blame game theory contributes to the literature on organizational misconduct and has implications for research on social evaluations

Laser annealing of silicon on sapphire

Silicon-implanted silicon-on-sapphire wafers have been annealed by 50-ns pulses from a Q-switched Nd : YAG laser. The samples have been analyzed by channeling and by omega-scan x-ray double diffraction. After irradiation with pulses of a fluence of about 5 J cm^–2 the crystalline quality of the silicon layer is found to be better than in the as-grown state

Auxiliary particle theory of threshold singularities in photoemission and X-ray absorption spectra: Test of a conserving T-matrix approximation

We calculate the exponents of the threshold singularities in the photoemission spectrum of a deep core hole and its X-ray absorption spectrum in the framework of a systematic many-body theory of slave bosons and pseudofermions (for the empty and occupied core level). In this representation, photoemission and X-ray absorption can be understood on the same footing; no distinction between orthogonality catastrophe and excitonic effects is necessary. We apply the conserving slave particle T-matrix approximation (CTMA), recently developed to describe both Fermi and non-Fermi liquid behavior systems with strong local correlations, to the X-ray problem as a test case. The numerical results for both photoemission and X-ray absorption are found to be in agreement with the exact infrared powerlaw behavior in the weak as well as in the strong coupling regions. We point out a close relation of the CTMA with the parquet equation approach of Nozi{\`e}res et al.Comment: 10 pages, 9 figures, published versio

Clustering in Highest Energy Cosmic Rays: Physics or Statistics?

Directional clustering can be expected in cosmic ray observations due to purely statistical fluctuations for sources distributed randomly in the sky. We develop an analytic approach to estimate the probability of random cluster configurations, and use these results to study the strong potential of the HiRes, Auger, Telescope Array and EUSO/OWL/AirWatch facilities for deciding whether any observed clustering is most likely due to non-random sources.Comment: 19 pages, LaTeX, 3 figure

Ultrahigh Energy Cosmic Rays: The state of the art before the Auger Observatory

In this review we discuss the important progress made in recent years towards understanding the experimental data on cosmic rays with energies \agt 10^{19} eV. We begin with a brief survey of the available data, including a description of the energy spectrum, mass composition, and arrival directions. At this point we also give a short overview of experimental techniques. After that, we introduce the fundamentals of acceleration and propagation in order to discuss the conjectured nearby cosmic ray sources. We then turn to theoretical notions of physics beyond the Standard Model where we consider both exotic primaries and exotic physical laws. Particular attention is given to the role that TeV-scale gravity could play in addressing the origin of the highest energy cosmic rays. In the final part of the review we discuss the potential of future cosmic ray experiments for the discovery of tiny black holes that should be produced in the Earth's atmosphere if TeV-scale gravity is realized in Nature.Comment: Final version.

Sensitivity of the carbon cycle in the Arctic to climate change

The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and human/cultural systems that may be irreversible on century time scales and have the potential to cause rapid changes in the earth system. The response of the carbon cycle of the Arctic to changes in climate is a major issue of global concern, yet there has not been a comprehensive review of the status of the contemporary carbon cycle of the Arctic and its response to climate change. This review is designed to clarify key uncertainties an vulnerabilities in the response of the carbon cycle of the Arctic to ongoing climatic change. While it is clear that there are substantial stocks of carbon in the Arctic, there are also significant uncertainties associated with the magnitude of organic matter stocks contained in permafrost and the storage of methane hydrates beneath both subterranean and submerged permafrost of the Arctic. In the context of the global carbon cycle, this review demonstrates that the Arctic plays an important role in the global dynamics of both CO2 and CH4. Studies suggest that the Arctic has been a sink for atmospheric CO2 of between 0 and 0.8 Pg C/yr in recent decades, which is between 0% and 25% of the global net land/ocean flux during the 1990s. The Arctic is a substantial source of CH4 to the atmosphere (between 32 and 112 Tg CH4/yr), primarily because of the large area of wetlands throughout the region. Analyses to date indicate that the sensitivity of the carbon cycle of the Arctic during the remainder of the 21st century is highly uncertain. To improve the capability to assess the sensitivity of the carbon cycle of the Arctic to projected climate change, we recommend that (1) integrated regional studies be conducted to link observations of carbon dynamics to the processes that are likely to influence those dynamics, and (2) the understanding gained from these integrated studies be incorporated into both uncoupled and fully coupled carbon–climate modeling efforts
