Abstract

Purpose

This study aims to analyse the effect of brand interactions such as personal interaction, problem-solving, reliability and store physical appearance on channel loyalty and purchase intention in optical physical stores.

Design/methodology/approach

The hypotheses are tested through quantitative research based on a questionnaire with a sample of 414 respondents. Researchers conduct multiple regressions to analyse the data.

Findings

The findings reveal that channel loyalty and purchase intention are positively influenced differently. Person-to-person interactions play a vital role in both constructs (dependent variables). This study also offers relevant managerial implications and future research avenues.

Originality/value

Despite the relevance of purchase intention in the literature, almost no studies have been published about the intention to buy glasses in the optical physical stores, a relevant contribution this paper offers to the literature. The finding that the store’s physical aspect did not prove to be influential for channel loyalty is also an innovative and relevant contribution of this research.

Objetivo

Este estudio analiza el efecto de las interacciones de marca, como la interacción personal, la resolución de problemas, la fiabilidad y la apariencia física de las tiendas en la lealtad al canal y la intención de compra en las tiendas ópticas físicas.

Diseño/metodología/enfoque

Las hipótesis se prueban a través de una investigación cuantitativa basada en un cuestionario con una muestra de 414 encuestados. Los investigadores utilizan regresiones múltiples para analizar los datos.

Conclusiones

Los resultados revelan que la lealtad al canal y la intención de compra están influenciadas positivamente de manera diferente. Las interacciones de persona a persona juegan un papel vital en los constructos (variables dependientes). Esta investigación también ofrece implicaciones de gestión relevantes y futuras vías de investigación.

Originalidad

A pesar de la relevancia de la intención de compra en la literatura, casi no se han publicado estudios sobre la intención de comprar gafas en tiendas ópticas físicas, una contribución relevante que este trabajo ofrece a la literatura. La constatación de que el aspecto físico de la tienda no ha demostrado ser influyente en la lealtad del canal también es una contribución innovadora y relevante de esta investigación.

Objetivo

Este estudo analisa o efeito das interações das marcas, tais como interação pessoal, resolução de problemas, fiabilidade e aparência física das lojas na fidelização de canais e intenção de compra em lojas físicas de ótica.

Conceção/metodologia/abordagem

As hipóteses são testadas através de investigação quantitativa com base num questionário com uma amostra de 414 inquiridos. Os investigadores usam regressões múltiplas para analisar os dados.

Conclusões

Abstract

Purpose – To analyze the concept of emerging infectious diseases, departing from the accepted definitions adopted by the Centers for Disease Control and Prevention (CDC, USA) and the now classical definition suggested by Grmek (1993, 1995). The emphasis of this chapter is on the roles that socio-economic and cultural changes play on the emergence of diseases.

Methodology – Bibliographical research.

Findings – Current definitions fail to address all instances of the emergence of disease. In order to illustrate the concept of emergence, we discuss two case studies. The first describes the constitution of abdominal angiostrongyliasis in Costa Rica. The second concerns an outbreak of Chagas disease that took place in 2005 in the state of Santa Catarina, Brazil.

Contribution – As a result of our analyses we propose a new classification of instances of emergence and emphasize the importance of an interdisciplinary approach for the understanding of diseases.

Abstract

Purpose

This paper aims to identify the specific parameters in developing a framework to assess the structural vulnerability of hospital buildings in Sri Lanka against tsunami. Along with that, the adaptability and suitability of the existing global frameworks in the Sri Lankan context are to be assessed.

Design/methodology/approach

In this study, Papathoma tsunami vulnerability assessment (PTVA)-4 model was used as the base in developing the abovementioned framework. Its adaptability and suitability in assessing hospital buildings in the country were considered under the case studies conducted in six selected hospitals in the Southern coastal belt of Sri Lanka. Under these case studies, data collection was done using the Rapid Visual Screening method where assessments were carried out through visual observations. The collected data were analyzed according to the aforementioned model for its suitability in evaluating the structural vulnerability of hospitals in Sri Lanka, against tsunami hazard.

Findings

From these case studies, it was identified that the use of the PTVA-4 model alone was insufficient to assess the structural vulnerability of the hospital buildings against the tsunami. Therefore, the model must be further improved with more relevant assessing attributes related to hospitals, suitable for the Sri Lankan context.

Originality/value

This paper identifies the specific structural assessment parameters required in assessing hospitals in the coastal belt of Sri Lanka, considering tsunami as the main hazard condition.

Abstract

Purpose

This study aims to identify the financial attributes of non-fungible tokens (NFTs) as safe havens, hedges or diversifiers against traditional (stock indices, foreign exchange, gold and government bonds) and digital (Bitcoin and Ethereum) assets.

Design/methodology/approach

The quantile via moments was utilized, and the data spanned from 20 September 2021 to 31 January 2022. The authors incorporated feasible generalized least squares (FGLS) and difference-generalized method of moments (diff-GMM) as the robustness check.

Findings

Overall, NFTs offer strongly safe havens, hedging and diversifier attributes against cryptocurrencies, while weak properties for traditional assets. The specific findings are: (1) Bored Ape Yacht Club (BAYC) serves as a strong hedge for Bitcoin during market rise; (2) Mutant Ape Yacht Club (MAYC) serves as a strong safe haven against Bitcoin during market bull; (3) Crypto punk (CP) provides strong safe havens properties for gold during market turmoil while serving as a strong hedge against gold and Bitcoin on average and (4) the three blue-chip NFTs are powered by Ethereum blockchain, thus serving as a diversifier against Ethereum.

Practical implications

Bitcoin investors are suggested to include NFTs in their investment portfolio to mitigate the losses when Bitcoin falls. Meanwhile, the inclusion of crypto punk is advised for risk-averse investors who invest in gold. NFTs are powered by the Ethereum blockchain, indicating co-movement among them and thus, serve as diversifiers. Policymakers and regulators are suggested to watch closely over NFTs' great development and restructure the existing policies and thus, stabilization of asset markets can be achieved.

Originality/value

The originality aspects are: (1) focusing on the three blue-chip NFTs (i.e. BAYC, MAYC and CP) that are categorized as the largest NFTs by floor market capitalization; (2) testing the NFT attributes (safe havens, hedges or diversifiers) against traditional and digital assets, a.k.a., cryptocurrencies and (3) panel setting on 14 countries with the highest NFT users.

Abstract

Purpose

This study investigates the effect of the day of the week on the volatility of cryptocurrencies. Thus, we reveal investors' perceptions of the day of the week.

Design/methodology/approach

The EGARCH model consists of the day of the week for 2019–2022 and the volatility of 11 cryptocurrencies.

Findings

Empirical results show that the weekend harms cryptocurrency volatility. Also, there was positive cryptocurrency volatility at the beginning of the week. Our findings show that weekdays and weekends significantly impact cryptocurrency volatility. Besides, cryptocurrency investors are sensitive to market movements, disclosures, and regulations during the week. Holiday mode and cognitive shortcuts may cause cryptocurrency traders to remain passive on weekends.

Research limitations/implications

This study has some limitations. We include 11 cryptocurrencies in the analysis by limiting cryptocurrencies according to market capitalizations. Further studies may analyze a larger sample. In addition, further studies may examine the moderator and mediator effects of other financial instruments.

Practical implications

The empirical results have research, social and practical conclusions from different aspects. Our analysis may contribute to determining trading strategies, risk management, market efficiency, regulatory oversight, and investment decisions in the cryptocurrency market.

Originality/value

The calendar effect in financial markets has extensive literature. However, cryptocurrencies' weekday and weekend effect needs to be adequately analyzed. Besides, studies analyzing cryptocurrency volatility are limited. We contribute to the literature by investigating the impact of days of the week on cryptocurrency volatility with a large sample and current data.

Abstract

Purpose

The application of condition-based maintenance on selected equipment can allow online monitoring using fixed, half-fixed or portable sensors. The collected data not always allow a straightforward interpretation and many false alarms can happen. The paper aims to discuss these issues.

Design/methodology/approach

Statistical techniques can be used to perform early failure detection. With the application of Cumulative Sum (CUSUM) Modified Charts and the Exponentially Weighted Moving Average (EWMA) Charts, special causes of variation can be detected online and during the equipment functioning. Before applying these methods, it is important to check data for independence. When the independence condition is not verified, data should be modeled with an ARIMA (p, d, q) model. Parameters estimation is obtained using the Shewhart Traditional Charts.

Findings

With data monitoring and statistical methods, it is possible to detect any system or equipment failure trend, so that we can act at the right time to avoid catastrophic failures.

Originality/value

In this work, an electro pump condition is monitored. Through this process, an anomaly and four stages of aggravation are forced, and the CUSUM and EWMA modified control charts are applied to test an online equipment monitoring. When the detection occurs, the methodology will have rules to define the degree of intervention.

Abstract

Purpose

This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.

Design/methodology/approach

The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.

Findings

This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.

Originality/value

The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

Abstract

Purpose

This paper aims to explore the impact of the origin of hops on the sensory and hedonic evaluation of highly involved craft beer consumers.

Design/methodology/approach

Data was collected through a between-subject tasting experiment, where the origin of hop was manipulated (imported vs locally grown). The craft beer samples used in the experiment were produced using hops of similar age but grown in two distinct places: USA (imported hop) and in the city of Ribeirão Preto, Brazil, where the experiment was conducted (locally grown hop). The sensory and hedonic evaluations of highly involved craft beer consumers (n = 100) were collected after tasting the samples.

Findings

The origin of hop proved to be significant in affecting participants’ sensory and hedonic evaluations. It was observed that women were more sensitive than men to the origin information: when information was given, differences were found only on men’s scores of dryness/astringency; while in women, significant differences were found not only in dryness/astringency, but also in bitterness and refreshing, which are important attributes in the sensory profile of craft beer. It was also confirmed the effect of localness in hop cultivation, once men’ and women’s scores on liking were higher for the sample brewed with locally grown hop.

Originality/value

To the best of the authors’ knowledge, this is the first work using craft beer brewed with hops cultivated in Brazil and a sample of Brazilian craft beer consumers, therefore, providing a significant contribution to the field of consumer behavior. Furthermore, it adds to the discussion on sex-/gender-related differences regarding sensory expectation and perception of foods.
