This study, based on data collected from low-ranking employees working in Polish hotels, tests a research model that investigates whether there are links between corporate social responsibility (CSR), operationalized as “self-related” CSR experiences and “others-related” CSR experiences, and job satisfaction and organizational commitment, and between both attitudes and work engagement. Structural equation modelling was used to assess these relationships, using a 20 point questionnaire answered by 412 respondents. The results indicate that “others-related” CSR experiences are positively associated with satisfaction and commitment, while “self-related” CSR experiences with the latter variable. Likewise, organizational commitment, unlike job satisfaction, was linked to work engagement. However, contrary to our a priori assumptions and prior research, it turned out that job satisfaction was not a predictor of commitment. The paper discusses theoretical and practical implications of the findings. The study's most important practical implication is that Polish hotel employees attach weight to responsible behaviour: the hotel industry should perceive CSR in terms of strategic significance. Companies that want a committed and engaged workforce – and, by extension, to enhance their competitiveness – should embrace CSR. The paper concludes by highlighting its limitations and suggesting future research avenues.  相似文献

Abstract

We use content analysis software to examine certain characteristics of communications arising from European Council meetings. These characteristics appear to explain a large proportion of variation in stock returns around the meeting dates. More specifically, stock market investors react favourably when the conclusions and declarations issued by heads of states convey a positive sentiment and demonstrate a stance of moral rectitude. On the other hand, the returns tend to be negative when the communications are obfuscated by an excessive use of abstract words and fixated on regional rather than global issues.  相似文献

Economic and financial data often take the form of a collection of curves observed consecutively over time. Examples include, intraday price curves, yield and term structure curves, and intraday volatility curves. Such curves can be viewed as a time series of functions. A fundamental issue that must be addressed, before an attempt is made to statistically model such data, is whether these curves, perhaps suitably transformed, form a stationary functional time series. This paper formalizes the assumption of stationarity in the context of functional time series and proposes several procedures to test the null hypothesis of stationarity. The tests are nontrivial extensions of the broadly used tests in the KPSS family. The properties of the tests under several alternatives, including change-point and I(1)I(1), are studied, and new insights, present only in the functional setting are uncovered. The theory is illustrated by a small simulation study and an application to intraday price curves.  相似文献

Using a sample of 76 countries, this paper examines the impact of major strikes against government and its policies on stock market behavior. An occurrence of a general strike is detrimental to the value of equities, as documented by the ceteris paribus 6.11% fall in dollar-denominated stock market indices of the affected countries. This event is also accompanied by a statistically significant increase in risk, as measured by the standard deviation of returns and Value-at-Risk metrics. Taken together, these results imply that general strikes have serious ramifications for stock market investors.  相似文献

The paper presents a new approach to exchange rate modelling that augments the CHEER model with a sovereign credit default risk as perceived by financial investors making their decisions. In the cointegrated VAR system with nine variables comprised of the short- and long-term interest rates in Poland and the euro area, inflation rates, CDS indices and the zloty/euro exchange rate, four long-run relationships were found. Two of them link term spreads with inflation rates, the third one describes the exchange rate and the fourth one explains the inflation rate in Poland. Transmission of shocks was analysed by common stochastic trends. The estimation results were used to calculate the zloty/euro equilibrium exchange rate.  相似文献

Aims: Non-vitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) are used to prevent stroke in patients with atrial fibrillation (AF). This paper aimed to evaluate the clinical efficacy and safety of NOACs when compared to VKAs by calculating the number needed to treat (NNT) at 2 years using incidence rates and hazard ratios (HRs) derived from a meta-analysis of studies conducted in real-world settings.

Materials and methods: HRs were sourced from a published systematic literature review and a meta-analysis of real-world evidence on the use of NOACs vs VKAs. Rivaroxaban, dabigatran, and apixaban vs VKAs were investigated. The efficacy outcomes included: a composite of ischaemic stroke and systemic embolism (IS/SE), ischaemic stroke (IS), and all-cause mortality. The safety analysis assessed major bleeding and intracranial haemorrhage (ICH).

Results: Superiority of NOACs vs VKAs was observed in 10/15 comparisons. Treating patients with rivaroxaban and dabigatran was associated with a reduced risk of IS and all-cause mortality compared to VKAs, with one death prevented every 22 and 32 patients, respectively, and one IS prevented every 206 and 166 patients, respectively. Rivaroxaban was significantly associated with a reduced risk of IS/SE compared to VKA (NNT: 107). No significant differences were observed between apixaban and VKAs. Dabigatran and apixaban were associated with a reduced risk of major bleeding compared to VKA (NNT: 59 and 38, respectively). No significant difference was observed between rivaroxaban and VKAs regarding major bleeding. Rivaroxaban, dabigatran, and apixaban were significantly associated with a reduced risk of ICH (NNT: 205, 115, and 108, respectively).

Limitations: Heterogeneity in definitions of major bleeding across studies.

Conclusions: The NNT calculation, when approached and interpreted properly, is a practical measure of the effectiveness of a treatment. The calculation based on HRs showed that NOACs are safe and effective alternatives to VKAs in real life.  相似文献

By drawing from the internalisation and institutional theories, as well as the organisational capability perspective, the paper analyses the moderating effects of parent control over foreign affiliates in relation to firm capabilities and institutional distance and their performance effects. These relationships are explored in the context of new MNEs from Poland as a mid-range emerging economy, for which ownership choices constitute critical decisions given their early stage of internationalisation. Our findings show that while firm capabilities drive foreign affiliate performance, the increase of parent control limits this beneficial effect, suggesting the potential occurrence of organisational inertia and reduction of learning in foreign markets. On the contrary, we also find partial evidence that the increase of parent control reduces the negative effect of institutional distance computed based on the Mahalanobis formula. Accordingly, the study suggests a certain ambiguity of parent control in affecting affiliate performance.  相似文献
