Abstract

Purpose

When investors experience extreme uncertainty, they seek “safe havens” to reduce their risk, to limit their losses and to protect the value of their portfolios. The purpose of this paper is to examine the safe-haven properties of Bitcoin compared to the stock market.

Design/methodology/approach

Based on intraday data, this study compares the price efficiencies of Bitcoin and Morgan Stanley Capital Index (MSCI) using Multifractal Detrended Fluctuation Analysis for the second half of 2020. This study then evaluates Bitcoin’s safe-haven property using Detrended Partial-Cross-Correlation Analysis (DPCCA).

Findings

This study finds that the price efficiency of Bitcoin is lower than that of MSCI. Further, Bitcoin was not a safe haven at any time for the MSCI index. The net cross-correlations between Bitcoin and MSCI are weak and they vary at different time scales.

Research limitations/implications

The behavior of market prices varies over time. Therefore, it is important to replicate this study for other time periods.

Social implications

The paper sheds light on the price behavior of Bitcoin during a period of instability. The results suggest that the construction of portfolios should differ based on the time horizons of the investors.

Originality/value

The authors compare Bitcoin against a global equity index instead of a specific country index or commodity. They also demonstrate the applicability of DPCCA in finance research.

Abstract

Purpose

Wine is an important profit center for restaurants. The purpose of this paper is to address some of the challenges and opportunities at the nexus of wine and hospitality, with an eye on relationship building between smaller wineries and dining establishments.

Design/methodology/approach

The paper is essay style with acknowledgments made to extant literature, as well as US industry-based intelligence.

Findings

Primary challenges facing small wineries trying to enter the restaurant market revolve around constraints imposed by the traditional distribution system mindset, as well as pricing issues affecting procurement and markup of wine for restaurant use, limited abilities to provide sufficient inventory and the lack of time and people resources. Counterpoint discussion reveals opportunities related to increased focus on experience-based wine sales in restaurants, the importance of the story and the value of co-branding.

Practical implications

Partnerships with restaurants can be a delicate yet desirable part of a small winery’s strategy. The key is to develop a mutually beneficial relationship, while fulfilling the objectives and missions of both winery and restaurant. When wineries and restaurants carve out the time and invest the people resources to successfully and purposefully co-brand, optimum symmetry is formed which leads to mutually valued dining and special gastronomic experiences for the winery/restaurant partners and their customers.

Originality/value

In a viewpoint format, the paper outlines and discusses the key elements of relationship building between small wineries and restaurants.

Abstract

Sustainable transport is often defined according to energy efficiency and environmental impacts. With global approval during Habitat III, however, a set of Sustainable Development Goals have become the focus for human development until 2030, underlining the relevance of health, equity and other social issues.

These goals raise the challenge of achieving significant progress towards ‘transport justice’ in diverse societies and contexts. While exclusion occurs for different reasons, discrimination, based on cultural roles, combines with sexual harassment and other mobility barriers to limit women’s mobility. This makes gender an area of particular interest and potential insight for considering equity within sustainability and its social components.

Using data from Metropolitan Santiago to ground a conceptual exploration, this chapter examines the equity implications of women’s travel patterns and sustainable transport. Key findings underline the importance of considering non-work trip purposes and achieving better land-use combinations to accommodate care-oriented trips. Moreover, barriers linked to unsafe public transport environments limit women’s mobility and, therefore, their participation. Women account for a disproportionately high number of walking trips, a situation that can be interpreted as ‘greater sustainability’ in terms of energy use and emissions, but suggests significant inequalities in access. Environmental and economic sustainability gains may be achieved at a high social cost, unless specific measures are taken.

Abstract

This paper analyzes how an infertile body is shaped by social discourses and reproductive technologies. Reproductive governances are articulated in this context by ideas and social values regarding family and motherhood, the binomial of infertility-TRA, legislation and norms and health professionals' practices. In addition, it shows how diverse infertile bodies experience (and withstand) these reproductive governances. Various sources have been consulted, including newspapers, biographical books, bibliographic sources from specialized literature and interviews carried out by the author.

Abstract

Purpose

Companies need to innovate to remain in the market and be competitive. Thus, success will depend on your internal resources and the external sources of knowledge used. The cooperation between univerity and industry (U–I) allows companies to access resources that, in general, they do not have, allowing them to achieve innovation, competitive advantages, and competitiveness. The purpose of this study is to understand the determinants that influence U–I cooperation in creating knowledge and innovation.

Design/methodology/approach

This study analyzes the determinants considered essential for companies to establish cooperation processes with universities. The research uses the last community innovation survey data set, data from 14 countries, and 28,743 observations. The method uses logistic regression.

Findings

The results confirm that the company's size, the innovative capacities associated with R&D, exportation and public funds are essential and significant determinants for the cooperation with universities. On the other hand, the acquisition of machinery and training programs are not a critical factor in establishing cooperation with universities that are not in the same country. The analysis considered companies cooperation with universities of the same country, from the European Union (EU) or other countries outside EU.

Originality/value

In addition to providing substantial theoretical contributions on the subject, this research also provides more information about the importance of U–I cooperation, allowing to characterize companies interested in developing U–I cooperation.

Abstract

Purpose

This study aims to investigate how relational capital derived by the buyer and supplier from the buyer-LSP and supplier-LSP dyads affects buyer-supplier adaptability and their relational performance.

Design/methodology/approach

Drawing upon the tenets of Social Capital Theory and Relational View, the authors performed exploratory research using a survey of 350 supply chain triads. Based on these data, the authors used Structural Equation Modeling to estimate the Higher Component Model (HCM) and test the research hypotheses.

Findings

The research results indicate that relational capital derived by the supplier from the supplier-LSP dyad has a strong and positive impact on buyer-supplier adaptability. On the other hand, relational capital derived by the buyer from the buyer-LSP dyad has no significant impact on buyer-supplier adaptability. The results also demonstrate that the effect of buyer-supplier adaptability on buyer-supplier relational performance is strong and positive. The obtained findings also suggest that buyer-supplier adaptability acts as a partial mediator between relational capital derived by buyer/supplier from the links with LSP and relational performance.

Research limitations/implications

The study has some limitations that guide directions for future research. First, along with relational capital, it might be worthwhile to also investigate the impact of structural and cognitive capital in supply chain triads to test whether and how these two dimensions of social capital contribute to buyer-supplier adaptability. It could be also interesting to include the LSP’s perception of relational capital in the model to shift the analysis from the organizational to the interorganizational level.

Originality/value

Given the increasing interest in complex structures of supply chains, this study investigates how one dyad affects other dyads in supply chain triads. Specifically, the study develops and empirically tests the construct of relational capital derived from the links with LSPs, and views adaptability as the result of two interacting parties.

Abstract

Purpose

This study aims to structure research on water resources in the hotel industry, identifying the key areas and research gaps in this field.

Design/methodology/approach

A systematic literature review of water use in the hotel industry has been performed using the Scopus and Web of Science databases. From 515 articles selected between the years 2000 and 2019, a sample of 58 articles was used to structure existing research on this subject.

Findings

Research is classified into four groups: water consumption, water management, impacts of water use and good practices, with different research methods and topics within each one. Existing research gaps and their causes are also discussed. The results show how academic research can help strengthen international methodologies that measure sustainability.

Research limitations/implications

Because of the search process, some publications on water consumption in the hotel industry may have been missed; also book chapters and conference papers were excluded. Furthermore, the authors recognise some subjectivity in the classification of articles.

Originality/value

To the authors’ knowledge, this is the first systematic analysis focussed on water use in the hotel industry. The findings can be used to build a research framework for this area, establishing an approach to cover research gaps and to connect academic research with general methodologies and indicators of sustainability, as well as improving data collection techniques in this field.

Abstract

Purpose

The purpose of this study is to examine the effect on the customer brand engagement (CBE) of followers of an eco-friendly restaurant of their perceptions of the originality of the firm-generated content posted online by the restaurant and the effect of CBE on brand advocacy and behavioural intentions to visit the restaurant, paying special attention to the moderating role of past visits to the restaurant.

Design/methodology/approach

The hypotheses were tested using structural equation modelling with a sample of 491 female Instagram users who follow the online account of a particular eco-friendly dining establishment. Two group comparisons were conducted to test the moderating effects in relationships between CBE and consumer–brand interactions (behavioural intentions to visit the restaurant and brand advocacy).

Findings

Followers’ perceptions of the originality of the material posted by the eco-friendly restaurant had a positive influence on CBE which, in turn, affected brand advocacy and behavioural intentions to visit the restaurant. Past visits moderated the relationship between CBE and consumer–brand interactions.

Practical implications

This study offers restaurants an understanding of how to develop marketing strategies targeted at females on visual-based social networks; it is shown that original posts encourage favourable responses, such as CBE, brand advocacy and behavioural intentions. Managers should organise events and invite their female followers to visit the restaurant.

Originality/value

This study adds to the knowledge about customer engagement by explaining how firm-generated content posted on Instagram drives CBE and provides specific suggestions as to how restauranteurs might engage online with their clients. This study goes beyond direct effects and analyses the moderating role of past visits to the restaurant on the relationships between CBE and consumer–brand interactions (visiting intentions and brand advocacy).

Abstract

Purpose

This study aims to explore and identify the information-seeking process and practices of those searching for the forcefully disappeared in Colombia. It answers the questions; how do families in Colombia seek information about a disappearance, how is this seeking process mediated and how are information barriers dealt with?

Design/methodology/approach

Based on document analysis and interviews with families and NGO representatives, this bottom-up study explores the trajectory of the families' information-seeking process to highlight the most salient information practices.

Findings

A general trajectory of a search for information is laid out. The overwhelming barriers to information forces families to carry the burden of becoming information providers. NGOs provide situated learning on how to document a disappearance and deal with the state. This knowledge is passed on to families creating communities of practices. The information produced here becomes the main source of knowledge about this crime.

Originality/value

It makes a new contribution to the field of information practices by introducing the context of enforced disappearances using the example of Colombia, identifying a significant information-seeking process.
