The Impact of Personal Values and Attitudes on Responsible Behavior toward the Environment

Prior research on nature-based tourism has examined determinants of tourists’ environmentally responsible behavior from a personal value perspective. However, a nature-based destination needs both the economic benefits from tourists’ spending and the environmental benefits from tourists’ environmentally responsible behavior. Thus, based on the value-belief-norm and trust transfer theories, this study integrated altruistic value and attitudes toward a nature-based destination’s eco-travel and the destination to predict destination loyalty and positive word-of-mouth about the eco-travel as well as environmentally responsible behavior among domestic tourists. This study collected and analyzed data from 289 domestic tourists visiting Jeju Island, South Korea. The results of the structural equation modeling indicated that altruistic value significantly influenced only attitude toward eco-travel, which positively affected attitude toward the destination, destination loyalty, environmentally responsible behavior, and positive word-of-mouth about the eco-travel. Attitude toward the destination significantly influenced destination loyalty. Based on these results, this study provided several theoretical and managerial implications for a sustainable nature-based destination

IS BITCOIN IMMUNE TO THE COVID-19 PANDEMIC?

This study examines how Bitcoin’s trading characteristics react to the COVID-19 pandemic, using detailed futures trading data from the Chicago Mercantile Exchange. The results show that volume-weighted Bitcoin futures return responds positively to the spikes of public interest. Meanwhile, the surges of pandemic information do not harm market quality. Volume, bid-ask spread, and trading frequency remain stable, indicating that the positive price reaction is not a result of a few small uninformed trades. Bitcoin's conditional beta on the S&P 500 index drops to near zero, while the conditional beta on gold more than doubles. These results indicate that traders have been using Bitcoin as a safe-haven asset after the pandemic outbreak

Deutsch im interkulturellen Interviewgespräch - Kommunikationsstrategie, Sprechweise und Prosodie

Kontrastive phonetische Untersuchungen sollten zu größerer Effektivität im interkulturellen Deutschunterricht verhelfen. Das bezieht sich nicht nur auf Vokale und Konsonanten, sondern vor allem auf den prosodischen Bereich. Das Verstehen und Verstandenwerden in der interkulturellen Kommunikation hängen weitgehend davon ab, inwieweit Sprecher und Hörer die prosodischen Eigenarten situationsadäquat beherrschen, erkennen und bewerten können. Der Fremdsprachenunterricht hat zum Ziel, die Lernenden auf interkulturelle Begegnungen vorzubereiten. Das Interview-Projekt “Deutsch für interkulturelle Kommunikation in Kasachstan” (2001–2003) ermöglichte Deutschlernenden interkulturelle Begegnungen im eigenen Land und ein praktisches und entdeckendes interkulturelles Lernen. Im Rahmen des Projektes wurden mündliche Interviews und interkulturelle Befragungen auch in Deutschland an den Universitäten Leipzig und Halle vorgenommen. Hörversuche zur vergleichenden auditiven Bewertung der Sprechweise und Prosodie des Deutschen im interkulturellen Interviewgespräch wurden mit deutschen Muttersprachlern und kasachischen Deutschlernenden durchgeführt. Im Beitrag werden behandelt und dargestellt: • Aspekte und Probleme des interkulturellen Deutschunterrichts • Interview-Projekt für interkulturelle Begegnungen im eigenen Land • Interkulturelle Kommunikationsstrategien (Ergebnisse der Umfragen) • Auditive Versuche mit deutschen und kasachischen Hörern • Schwerpunkte der kontrastiven Phonetik Deutsch-Kasachisch und einige Empfehlungen für den interkulturellen Deutschunterricht

Stress-Induced Nuclear-to-Cytoplasmic Translocation of Cyclin C Promotes Mitochondrial Fission in Yeast

Mitochondrial morphology is maintained by the opposing activities of dynamin-based fission and fusion machines. In response to stress, this balance is dramatically shifted toward fission. This study reveals that the yeast transcriptional repressor cyclin C is both necessary and sufficient for stress-induced hyperfission. In response to oxidative stress, cyclin C translocates from the nucleus to the cytoplasm, where it is destroyed. Prior to its destruction, cyclin C both genetically and physically interacts with Mdv1p, an adaptor that links the GTPase Dnm1p to the mitochondrial receptor Fis1p. Cyclin C is required for stress-induced Mdv1p mitochondrial recruitment and the efficient formation of functional Dnm1p filaments. Finally, coimmunoprecipitation studies and fluorescence microscopy revealed an elevated association between Mdv1p and Dnm1p in stressed cells that is dependent on cyclin C. This study provides a mechanism by which stress-induced gene induction and mitochondrial fission are coordinated through translocation of cyclin C

3 mm GMVA Observations of Total and Polarized Emission from Blazar and Radio Galaxy Core Regions

We present total and linearly polarized 3 mm Global mm-VLBI Array images of a sample of blazars and radio galaxies from the VLBA-BU-BLAZAR 7 mm monitoring program designed to probe the innermost regions of active galactic nuclei (AGN) jets and locate the sites of gamma-ray emission observed by the Fermi-LAT. The lower opacity at 3 mm and improved angular resolution, on the order of 50 microarcseconds, allow us to distinguish features in the jet not visible in the 7 mm VLBA data. We also compare two different methods used for the calibration of instrumental polarisation and we analyze the resulting images for some of the sources in the sample.Comment: Polarised Emission from Astrophysical Jets, June 12-16, 2017, Ierapetra, Greec

Prevalence of anginal symptoms and myocardial ischemia and their effect on clinical outcomes in outpatients with stable coronary artery disease: data from the international observational CLARIFY registry

Importance: In the era of widespread revascularization and effective antianginals, the prevalence and prognostic effect of anginal symptoms and myocardial ischemia among patients with stable coronary artery disease (CAD) are unknown.<p></p> Objective: To describe the current clinical patterns among patients with stable CAD and the association of anginal symptoms or myocardial ischemia with clinical outcomes.<p></p> Design, Setting, and Participants: The Prospective Observational Longitudinal Registry of Patients With Stable Coronary Artery Disease (CLARIFY) registry enrolled outpatients in 45 countries with stable CAD in 2009 to 2010 with 2-year follow-up (median, 24.1 months; range, 1 day to 3 years). Enrollees included 32 105 outpatients with prior myocardial infarction, chest pain, and evidence of myocardial ischemia, evidence of CAD on angiography, or prior revascularization. Of these, 20 291 (63.2%) had undergone a noninvasive test for myocardial ischemia within 12 months of enrollment and were categorized into one of the following 4 groups: no angina or ischemia (n = 13 207 [65.1%]); evidence of myocardial ischemia without angina (silent ischemia) (n = 3028 [14.9%]); anginal symptoms alone (n = 1842 [9.1%]); and angina and ischemia (n = 2214 [10.9%]).<p></p> Exposures: Stable CAD.<p></p> Main Outcome and Measure: The composite of cardiovascular (CV)–related death or nonfatal myocardial infarction.<p></p> Results: Overall, 4056 patients (20.0%) had anginal symptoms and 5242 (25.8%) had evidence of myocardial ischemia on results of noninvasive testing. Of 469 CV-related deaths or myocardial infarctions, 58.2% occurred in patients without angina or ischemia, 12.4% in patients with ischemia alone, 12.2% in patients with angina alone, and 17.3% in patients with both. The hazard ratios for the primary outcome relative to patients without angina or ischemia and adjusted for age, sex, geographic region, smoking status, hypertension, diabetes mellitus, and dyslipidemia were 0.90 (95% CI, 0.68-1.20; P = .47) for ischemia alone, 1.45 (95% CI, 1.08-1.95; P = .01) for angina alone, and 1.75 (95% CI, 1.34-2.29; P <.001) for both. Similar findings were observed for CV-related death and for fatal or nonfatal myocardial infarction.<p></p> Conclusions and Relevance: In outpatients with stable CAD, anginal symptoms (with or without ischemia on noninvasive testing) but not silent ischemia appear to be associated with an increased risk for adverse CV outcomes. Most CV events occurred in patients without angina or ischemia

FPGA design of the fast decoder for burst errors correction

The paper is about FPGA design of the fast single stage decoder for correcting burst errors during data transmission. The decoder allows correcting burst errors with 3 bits for a 15 bit codeword and a 7 bit check unit. The description of a generator polynomial search algorithm for building error-correcting codes was represented. The module structure of the decoder was designed for FPGA implementation. There are modules, such as remainder, check_pattern, decoder2, implemented by asynchronous combinational circuits without memory elements, and they process each codeword shift in parallel. Proposed implementation allows getting high performance about ~20 ns
