Abstract

Purpose

The purpose of this paper is to evaluate the levels of food safety knowledge, attitudes and practices (KAP) of consumer.

Design/methodology/approach

In total, 1,161 volunteers were included in this study, which has been developed to measure the knowledge, attitudes and behaviors of adults on food safety. Study data were collected through an online survey technique.

Findings

A statistically significant difference was determined between male and female participants and also at the education level considering total food safety attitude and practice scores (p < 0,001). It was determined that university graduates had higher scores at all scales than the median scores. When an assessment was made on the body mass index of the participants, it was seen that the implementation and attitude scales were statistically different from each other, and in paired comparisons on these scales, the average scores of normal-weight individuals were observed higher in the sub-dimensions than slightly obese individuals (p < 0.007; p < 0.001).

Research limitations/implications

Even though the population of the study was adults living in different cities, the results should not be generalized to all adults and the whole country. Also, the fact that the answers to the questions were not face-to-face, could create a bias. Although the reliability coefficient was found to be high, the data reported by the individuals participating in the study about their behavior formed the study results.

Originality/value

This study makes an important contribution to the literature. Determining the knowledge, attitude and behavior of consumers about food safety is important in ensuring food safety.

Abstract

Purpose

The purpose of this paper is to present the results of a particle swarm optimization (PSO) method applied in the design of a square-loop frequency selective surface (FSS) via the equivalent circuit model (ECM), considering the dielectric effective permittivity as a variable in the optimization problem.

Design/methodology/approach

In the optimization process considered, besides the FSS square loop geometric parameters, the thickness and relative permittivity of dielectric material used as support are included as variables in the search space, using for this a model of dielectric effective permittivity introduced by the authors in a previous work.

Findings

Square loops were designed and the obtained results were compared with designs reported in literature for applications in wireless local area network and long-term evolution 4G systems. The low computational cost is remarkable as well as the acceptable accuracy obtained with the proposed approach. The PSO method results were implemented with the ECM and compared with those obtained via Ansys – high frequency structure simulator commercial software simulations.

Originality/value

The lack of a model of dielectric effective permittivity for the ECM causes a restricted search space in the stochastic FSS design process limited to only geometric parameters, as it is reported in the available literature. The proposed approach simplifies and makes more flexible the design process, and allows guiding the FSS design to unit cell surface and/or dielectric thickness of small dimensions.

Abstract

Purpose

This study aims to elucidate the volatility spillovers among commodities, equities and socially responsible investments, underpinning their dynamic correlations during the economic instability wrought by the COVID-19 pandemic and associated financial crises.

Design/methodology/approach

This research quantitatively analyzes volatility transmission across various financial assets from January 2005 to October 2020 by employing the Diebold and Yilmaz (2012) spillover index. The methodology incorporates a temporal examination to capture the evolution of volatility dependencies pre and post the emergence of COVID-19.

Findings

The findings indicate substantial volatility spillovers among the assets in question, aligning with the current financialisation of commodity markets and a rise in financial market integration. These spillovers also show variation over time. Notably, the interconnectedness among the assets intensifies during periods of stress. For instance, the total spillover index significantly surpassed 80% toward the end of January 2020, following the onset of the COVID-19 crisis. Furthermore, the results imply that financial markets appear to be segmented.

Practical implications

The findings afford investors a more comprehensive insight into both the character and scale of the interdependencies across a broad array of financial markets. Indeed, grasping the extent to which financial markets are segmented or integrated during times of stress and stability is crucial for investors. Such understanding is key to more accurately evaluating risks, diversifying investment portfolios and devising more efficient hedging strategies.

Originality/value

This study contributes to financial literature by offering a comprehensive investigation into the spillover effects across a diverse set of asset classes during an unprecedented global health crisis, filling a gap in existing research on market behavior against the backdrop of a pandemic-induced financial crisis.

Abstract

Purpose

Owing to the growing evidence of crypto asset connectedness and correlation with traditional financial assets, this study sought to determine if there is a time-varying correlation and/or connectedness between the stablecoin market and the currencies of emerging market and developing economies (EMDEs) with significant cryptocurrency penetration.

Design/methodology/approach

This study uses a probabilistic principal component analysis (PPCA) to create stablecoin and EMDEs currency returns and volatility indices for EMDEs with significant cryptocurrency penetration. We then employ a time-varying correlation and time-varying parameter vector autoregressive (TVP-VAR) connectedness measures to document the time-dependent correlation and connectedness between the EMDE currencies and the stablecoin market.

Findings

The result points to a spillover of return shocks from the EMDE currencies to the stablecoin market prior to and after the COVID-19 pandemic. This is indicative of a flight-to-safety role of stablecoins for EMDE currencies. This calls for increased attention to the stablecoin market by money market investors and monetary authorities.

Originality/value

The paper contributes to the growing cryptocurrency and finance literature by empirically examining the level of connectedness between stablecoins and emerging market currencies. Knowing the relationship (correlation) and shock spillover (connectedness) between the stablecoins and the EMDE currencies will be valuable to currency investors’ diversification and hedging strategies, and to macroeconomic policymakers in designing and implementing regulation.

Abstract

Purpose

This study examines the effect of taxes, similar financial liabilities, and demographic variables such as respondent age, company age, and field of operation on the table wine market in Turkey.

Design/methodology/approach

An online survey was conducted on the wine producers and importers via SurveyMonkey. Thirty-six survey questions were answered using a five-point Likert scale. The responses obtained from 51 owners and administrators of wine companies were analyzed using the Statistical Package for the Social Sciences 23 program.

Findings

Excise and value-added taxes affected the amount and price of table wine production in Turkey, whereas the banderole affected quality and price. The excise tax, value-added tax, banderole, Resource Utilization Support Fund, customs duty, and authorizations also affected the amount, quality and price of table wine imports. Although financial liabilities such as the banderole, Resource Utilization Support Fund and authorizations required for import do not constitute a heavy load on wine costs, they do have similar effects as other taxes on table wine imports.

Research limitations/implications

A limitation of this study was its sample size. Only 51 individuals responded, as it was an online questionnaire. However, this did not compromise the representativeness of the sample with regard to the company's field of operation (production and import of table wine), lending credibility to the opinions provided.

Originality/value

This study establishes that, contrary to popular belief, decisions regarding wine production and import are not solely affected by a heavy tax burden. Other factors, such as the banderole, Resource Utilization Support Fund, ages of companies and respondents and authorizations required for import, which are not viewed as a heavy burden in monetary terms, also prove to be decisive.

Abstract

Purpose

The slow food movement has become increasingly widespread globally in recent years. This paper focuses on explaining how Turkish cuisine, which has a deep-rooted history, meshes with the slow food movement and how this movement affects consumer behavior.

Design/methodology/approach

Based on expert opinion analysis with academics knowledgeable about the food industry and gastronomy, this paper explores how the slow food movement in Turkiye is evolving and how consumers perceive it. Content analysis was applied to the data obtained from the personal interviews.

Findings

The authors find that the slow food movement creates a strong brand image for businesses that rely on emphasizing the responsibility to the ecological system while appealing to the five senses of consumers. It already shows great potential even in emerging markets where typical household discretionary income is modest.

Practical implications

Based on key theories regarding all sales activism cases, the authors have offered insights into the dynamics, motivations and techniques of the case. Ensuring the preservation of the slow food movement, framing and creating associations need to be examined.

Originality/value

Slow food is a movement that emerged against the standard, fast, tasty, but unhealthy products of the fast-food industry. It entails product variety, local flavors and preference for the single-flavor focus embedded in the fast-food movement. The movement started with considerations of gastronomy and later was institutionalized as a social movement phenomenon. Later, it expanded its base to activism, targeting various social issues.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between CRM dimensions (i.e. customer orientation, CRM organization, knowledge management, and technology based CRM) and various aspects of organization performance (i.e. financial, customer, internal process, and learning and growth) in Malaysian hotels.

Design/methodology/approach

This is a quantitative study, the response came from the managers of 152 Malaysian hotels (3 to 5 star) and data collected was subjected to correlation and regression analysis in pursuance of the study's stated objectives.

Findings

The results of this study suggest that all dimensions of CRM (i.e. customer orientation, CRM organization, knowledge management and technology based CRM) have a positive and significant impact on different perspectives of hotel performance. However, CRM technology failed to show a significant relationship with learning and growth perspective of hotel performance.

Research limitations/implications

An emphasis has been placed on the direct relationship between CRM dimensions and organization performance perspectives as well as, the study concentrated only on 3 to 5 star hotels.

Practical implications

Meaningful implications are made that building an extensive and effective CRM dimensions in hotel firms is crucial to face a high competition and improve performance in Malaysia hotel sector.

Originality/value

The paper addresses CRM dimensions issues specifically for hotels in Malaysia.

Abstract

Purpose

Extant literature indicates that people use existing social networks for various collective activities as there is a cost involved to create and maintain separate networks for different activities. The authors build on the relational sociology framework and test this assertion in by examining a dairy cooperative society, which is a community organization. We hypothesize that the cooperative members are likely to use existing social networks to operationalize their cooperative (dairy-related matters) and other social and personal relations. This study tests the hypothesis by studying information sharing relations among the dairy cooperative members in two different social networks: the dairy information network and social information network.

Design/methodology/approach

This study uses social network analysis to analyze relational data.

Findings

The study finds that the members of the dairy cooperative maintain both information sharing networks separately and that each network has different control and efficiency mechanisms.

Originality/value

The findings contradict the assertions of existing literature and establish that people ensure their business relations remain separated from their social relations to avoid the possibility of social conflicts affecting their business activities.

Abstract

Purpose

This study aims to investigate the impact of the COVID-19 pandemic on both of stock prices and investor's sentiment in China during the onset of the COVID-19 crisis.

Design/methodology/approach

In this study, the ADCC-GARCH model was used to analyze the asymmetric volatility and the time-varying conditional correlation among the Chinese stock market, the investors' sentiment and its variation. The authors relied on Diebold and Yilmaz (2012, 2014) methodology to construct network-associated measures. Then, the wavelet coherence model was applied to explore the co-movements between these variables. To check the robustness of the study results, the authors referred to the RavenPack COVID sentiments and the Chinese VIX, as other measures of the investor's sentiment using daily data from December 2019 to December 2021.

Findings

Using the ADCC-GARCH model, a strong co-movement was found between the investor's sentiment and the Shanghai index returns during the COVID-19 pandemic. The study results provide a significant peak of connectivity between the investor's sentiment and the Chinese stock market return during the 2015–2016 and the end of 2019–2020 turmoil periods. These periods coincide, respectively, with the 2015 Chinese economy recession and the COVID-19 pandemic outbreak. Furthermore, the wavelet coherence analysis confirms the ADCC results, which revealed that the used proxies of the investor's sentiment can detect the Chinese investors' behavior especially during the health crisis.

Practical implications

This study provides two main types of implications: on the one hand, for investors since it helps them to understand the economic outlook and accordingly design their portfolio strategy and allocate decisions to optimize their portfolios. On the other hand, for portfolios managers, who should pay attention to the volatility spillovers between investor sentiment and the Chinese stock market to predict the financial market dynamics during crises periods and hedge their portfolios.

Originality/value

This study attempted to examine the time-varying interactions between the investor's sentiment proxies and the stock market dynamics. Findings showed that the investor's sentiment is considered a prominent channel of shock spillovers during the COVID-19 crisis, which typically confirms the behavioral contagion theory.

Abstract

Purpose

This study aims to investigate the viewpoints of heterodox economic thoughts and Islamic economic thought concerning the concept of waste. Additionally, it explores the shared criticisms that both perspectives hold against mainstream economic thought in relation to waste.

Design/methodology/approach

First of all, the concept of waste is examined and the global effects of waste are investigated. Criticisms directed in the context of waste in mainstream economics in the context of heterodox school thoughts are examined. Likewise, criticisms directed in the context of waste in mainstream economics in the context of Islamic economic thoughts are examined. Finally, the common and different aspects of heterodox and Islamic economic thoughts were discussed, and the common criticisms of mainstream economic thought’s point of view toward waste were examined. This study is a theoretical, qualitative study.

Findings

Although both ideas have different aspects, heterodox and Islamic economic thoughts believe that the mainstream economy, which is based on capitalism and materialism, creates waste by ignoring the long-term social and environmental consequences of economic activity. They argue that the pursuit of profits and growth, without considering the impact on society and the environment, leads to an inefficient and unsustainable use of resources.

Originality/value

The best author’s knowledge, by emphasizing the common and different aspects of Islamic economics and heterodox thoughts, this study is the first to examine the concept of waste in the context of the common aspects of these ideas.
