The meaning of my feelings depends on who I am: work-related identifications shape emotion effects in organizations

Theory and research on affect in organizations has mostly approached emotions from a valence perspective, suggesting that positive emotions lead to positive outcomes and negative emotions to negative outcomes for organizations. We propose that cognition resulting from emotional experiences at work cannot be assumed based on emotion valence alone. Instead, building on appraisal theory and social identity theory, we propose that individual responses to discrete emotions in organizations are shaped by, and thus depend on, work-related identifications. We elaborate on this proposition specifically with respect to turnover intentions, theorizing how three discrete emotions - anger, guilt, and pride - differentially affect turnover intentions, depending on two work-related identifications - organizational and occupational identification. A longitudinal study involving 135 pilot instructors reporting emotions, work-related identifications, and turnover intentions over the course of one year provides general support for our proposition. Our theory and findings advance emotion and identity theories by explaining how the effects of emotions are dependent on the psychological context in which they are experienced

An algorithm for the calculation of heavy ion ranges in SiO2

The heavy ion ranges in amorphous SiO2 have been calculated by using a technique based on solution of first order ODE’s. Br, Au, Hg, Bi, projectiles have been chosen as incident ion. Since the target is assumed to be amorphous, Bragg’s rule can be used to calculate electronic and nuclear stopping powers in the compound. Numerical solutions have been performed by using Fehlberg fourth-fifth order Runge-Kutta method. The results are compared with experimental data, as well as with the result of the Monte Carlo program SRIM and other standard procedures such as PRAL and WS [19]. It is found that the agreement between our method and the experiment is good and within 10%

Effect of repeated ceramic firings on the marginal and internal adaptation of metal-ceramic restorations fabricated with different CAD-CAM technologies.

STATEMENT OF PROBLEM: The use of computer-aided design and computer-aided manufacturing (CAD-CAM) for metal-ceramic restorations has increased with advances in the technology. However, little is known about the marginal and internal adaptation of restorations fabricated using laser sintering (LS) and soft milling (SM). Moreover, the effects of repeated ceramic firings on the marginal and internal adaptation of metal-ceramic restorations fabricated with LS and SM is also unknown. PURPOSE: The purpose of this in vitro study was to investigate the effects of repeated ceramic firings on the marginal and internal adaptation of metal-ceramic copings fabricated using the lost wax (LW), LS, and SM techniques. MATERIAL AND METHODS: Ten LW, 10 LS, and 10 SM cobalt-chromium (Co-Cr) copings were fabricated for an artificial tooth (Frasaco GmbH). After the application of veneering ceramic (VITA VMK Master; VITA Zahnfabrik), the marginal and internal discrepancies of these copings were measured with a silicone indicator paste and a stereomicroscope at ×100 magnification after the first, second, and third clinical simulated ceramic firing cycles. Repeated measures 2-way ANOVA and the Fisher LSD post hoc test were used to evaluate differences in marginal and internal discrepancies (α=.05). RESULTS: Neither fabrication protocol nor repeated ceramic firings had any statistically significant effect on internal discrepancy values (P>.05). Marginal discrepancy values were also statistically unaffected by repeated ceramic firings (P>.05); however, the fabrication protocol had a significant effect on marginal discrepancy values (P.05). CONCLUSIONS: All groups demonstrated clinically acceptable marginal adaptation after repeated ceramic firing cycles; however, the LS and SM groups demonstrated better marginal adaptation than that of LW group and may be appropriate clinical alternatives to LW

Rates of new asthma diagnosis in patients with allergic rhinitis in otorhinolaryngology practice in the Eastern Black Sea region

Background: Allergic rhinitis (AR) is a common disease observed in otorhinolaryngology (ORL) practice. The aim of the study was to determine the rates of new asthma diagnosis in the patient population newly diagnosed with AR in otorhinolaryngology (ORL) practice in the Eastern Black Sea region. Material/Methods: This study retrospectively evaluated the files of patients admitted to an ORL outpatient clinic in Rize, Turkey between April 2011 and June 2012 and who were diagnosed with AR for the first time upon detection of aeroallergen sensitization in the prick test. Within this patient group, the files of patients who were also diagnosed with asthma in the same time period were examined. The files of patients who had previously been diagnosed with or treated for AR and/or asthma and with nasal polyposis and lower respiratory tract disease were excluded from the study. Results: There were 267 patients with a mean age of 37.5±14.9 (10–77 years) diagnosed with AR for the first time in the ORL outpatient clinic. The most common allergens were Dermatophagoides pteronyssinus (81.3% [217/267]), D. farinae (73.8% [197/267]), and grass mix (61.4% [164/267]). Of this patient group, 29.2% were diagnosed with asthma: 15% (40/267) with intermittent asthma, 13.9% (37/267) with mild persistent asthma, and 0.3% (1/267) with moderate persistent asthma. Conclusions: A rate of 29.2% for new asthma diagnoses in the Eastern Black Sea region in patients diagnosed with AR for the first time indicates a need to examine asthma complaints in all patients newly diagnosed with AR in ORL practices. © Med Sci Tech, 2016
