ABSTRACT

Chefs working at hotels, restaurants, and public institutions play a major role in food safety. The aim of this study is to explore attitudes and practices regarding food safety issues among chefs in the Cappadocia region, Turkey. The data was collected using a convenience sampling method of the non-probability sampling technique. The survey was conducted between the period of September 2018 and November 2018, and 108 chefs working at hotels, restaurants, and public institutions participated. The data were analyzed using frequencies, exploratory factor analysis, independent sample t-test, ANOVA, correlation, and simple linear regression analyses. Most of the chefs (79.6%) had taken a basic food safety training course. The findings reveal that there are statistically significant (p < .05) differences between groups: (a) demographics and attitudes, and (b) demographics and practices. The findings also show that there is a significant (p < .05) and positive correlation (r = 0.48) between the attitudes and practices of chefs. This study posits that food safety trained chefs have higher scores in terms of both attitudes and practices than those who have not received. It is recommended that all chefs should be encouraged to attend food safety training programs. Practical and academic implications are discussed in detail.  相似文献

Chain-form crime partnerships and intelligence sharing by national authorities to detect cross-border partners create multiple externalities in the combat against transnational crimes and illicit trafficking. Cooperative enforcements that minimize global harms prioritize the country with lower intelligence production and/or superior detection capability. In equilibrium, as in practice, national enforcements are underbudgeted and might prioritize the wrong side – predominantly the high-budget, high-harm country. Governments might not share intelligence out of fear of importing enforcement burden, and harmonizing criminal sanctions alone might not be effective. Shocks on crime deterrence in a target country are first absorbed by source countries, implying weaker horizontal crime transfer effects than projected.  相似文献

The recent growth in digital marketing investments and revenues has attracted the attention of both marketing practitioners and scholars. However, this growth has dramatically increased users' exposure to ad messages, encouraging consumers to avoid them. Therefore, ad avoidance has become a major problem for marketing practitioners. Although researchers have become much more interested in this subject over the past two decades, the body of knowledge on ad avoidance in the digital environment remains fragmented due to the lack of a comprehensive review. Therefore, a holistic overview study is needed that focuses on the big picture and can help researchers to understand the literature comprehensively. This study aims to provide a comprehensive understanding of the topic using a systematic literature review approach on digital ad avoidance. To this end, we provide an in-depth content analysis of 56 relevant articles published in 31 peer-reviewed scientific journals up to December 31, 2021. Based on a theories, contexts, characteristics, and methods (TCCM) framework, the study results shed light on ‘what do we know, how do we know, and where should research about digital ad avoidance research be heading?’ Additionally, drawing on the content analysis, we have presented an integrative framework that considers antecedents, outcomes, mediators, and moderators, which can help develop the field systematically and guide future research. By doing so, we think this review meets the need to give an overview of the state-of-the-art scientific body of knowledge on digital ad avoidance and makes important and solid contributions to the literature, practical implications, and future research directions based on the findings.  相似文献

We compare inflation forecasts of a vector autoregressive fractionally integrated moving average (VARFIMA) model against standard forecasting models. U.S. inflation forecasts improve when controlling for persistence and economic policy uncertainty (EPU). Importantly, the VARFIMA model, comprising of inflation and EPU, outperforms commonly used inflation forecast models.  相似文献

The links between exchange-rate movements and gold-price fluctuations have been extensively studied in earlier research using various econometric techniques. Our contribution to this research is that we apply a novel nonparametric causality-in-quantiles test to study the causal links between exchange-rate movements and gold-price fluctuations. We use daily data for the sample period 1994–2015 for major gold-producing countries to illustrate the novel test. We find that, for the majority of countries, gold-price fluctuations help to predict in sample the returns and the volatility of exchange rates. While exchange-rate movements predict in sample gold volatility, they do not predict gold returns.  相似文献

This paper investigates the channels through which the middle class may matter for consumption growth. Using several different middle‐class measures and a panel of 105 developing countries spanning the period 1985–2013, we find that a larger middle class influences consumption growth primarily through higher levels of human capital accumulation. There is also a significant direct effect of middle‐class size on consumption growth, which is more pronounced in the latter half of the sample, the 2000–2013 period.  相似文献

This paper assesses the effects of real depreciation on the economic performance of Turkey by considering quarterly data from 1987:I to 2001:III. The empirical evidence suggests that, contrary to classical wisdom, the real depreciations are contractionary, even when external factors like world interest rates, international trade, and capital flows are controlled. Moreover, the results obtained from the analyses indicate that real exchange rate depreciations are inflationary.  相似文献
