Abstract

Purpose

Diverse factors may influence travelers when choosing a hotel. Even though breakfast is often commented on in hotel and booking sites, its relative role in hotel selection is rarely studied. This paper aims to determine which attributes clients consider essential regarding the option towards a hotel and their hierarchy namely of breakfast.

Design/methodology/approach

A systematic review was performed in Scopus, ISI-Web of Science and Google Scholar, including relevant original manuscripts published in all languages between 1998 and 2018.

Findings

Out of 337 initial references, 25 manuscripts were included. Features related to facilities and services were considered in most manuscripts with 21 and 20 citations, respectively, as being the more relevant factors in hotel selection. Room and accommodation were ranked first as the most important characteristic regarding the option for a hotel, whereas breakfast was only referred to in two articles, published in 2015 and 2017, rated in the tenth and fourth positions, respectively.

Research limitations/implications

Breakfast seems to be addressed in recent published manuscripts, what may reflect a trend toward its evaluation in travelling experiences. More studies should address the relevance of breakfast and food to (diverse type of) costumers, and managers should also consider these factors when advertising their hotels.

Originality/value

To the best of the authors’ knowledge, this is the first systematic approach to this question, emphasizing the apparent contradiction of breakfast being often cited in booking sites and not adequately studied in tourism research.

Abstract

Purpose

The purpose of this paper is to conduct a systematic literature review (SLR) to identify the main firm-level performance indicators and group them in dimensions that support decision-making in the wine industry.

Design/methodology/approach

To achieve this goal, an SLR approach was conducted in the Scopus database from 2009 to 2019. From a set of 607 articles, only 25 studies related to firm-level performance indicators were considered and, following an inductive thematic analysis and an interpretative synthesis, separated into different specific foci that include social, economic and environmental dimensions.

Findings

There is a limited number of papers identifying indicators regarding the firm-level performance of wine firms, and even fewer studies including indicators on an integrated approach to measure the different dimensions of firm performance. This paper documents that economic and environmental indicators cover 78.2% of all SLR indicators analyzed. As this group of indicators is limited to a set of sub-dimensions, this paper found that several groups of indicators are misrepresented, such as product portfolio or certifications related to marketing activities and indicators covering purchasing and supply chain activities, which play a crucial role in the competitiveness of the wine industry.

Practical implications

For practitioners, it discloses the most pertinent indicators they need to improve to craft their business strategies. This framework is of added value for policymakers to customize their support programs for specific producers to develop their competitive strategies. It could be deployed in teaching programs as a tool to address the importance of aligning different types of indicators to achieve firm-level performance in the wine industry.

Originality/value

This study contributes to the literature identifying a framework of analysis that includes indicators of four dimensions, namely, economic, social, territorial and environmental. This framework aims to relate performance measures to corporate strategy as a management control tool. The framework intends to improve the fit between firms’ activities and their competitive context and to be flexibly adapted to various products/firms in the wine industry.

Abstract

Purpose

The purpose of this paper is to understand the main perceived impacts of overtourism in Portugal and the reactions of tourism stakeholders in the main Portuguese cities, especially the host.

Design/methodology/approach

This study uses a qualitative approach, based on the analysis of news published in Portuguese newspapers between March 2018 and March 2019, applying Bardin’s (2011) content analysis and matching with the theory as proposed by Laville and Dionne (1999).

Findings

The study reveals that the main perceived impacts are the evictions and transformation of old residence into short-term rentals (e.g. Airbnb) and small hotels, besides other impacts such as garbage in the streets, gentrification, loss of security and others.

Research limitations/implications

The study considered the period of one year, being a limitation of analysis for contexts within that period, as well as the possible partiality of how the context of overtourism is dealt by newspapers.

Practical implications

This study seeks to understand the context of overtourism and its perception by the hosts and aims to present a basis of tourism planning for public and private sector stakeholders, in order to provide a better visit experience to the tourist, without losing the hosts’ quality of life.

Originality/value

Studies using newspapers as sources of data are rare. The newspapers are considered local witnesses; therefore, they bear important information for several purposes, not just for tourism but for other realities or contexts.

Abstract

Purpose

The purpose of this paper is to explore women's perceptions about the benefits and risks of fish consumption, while exploring differences on their views about wild and farmed fish, considering light fish consumers.

Design/methodology/approach

The methodology adopted is exploratory, using focus group technique, segregating women by education level (higher education versus lower education). A focus group guide was designed, taking into account the following dimensions: attitudes towards fish consumption and perceptions towards farmed fish relative to wild fish, also considering risk perceptions related to farmed versus wild fish.

Findings

This study has shown that fish consumers enjoy the taste of fish and they are strongly convinced that eating fish is healthy. The main reason for their low fish consumption is related to perceive lacking of convenience. Women with higher education levels expressed additional knowledge considering different aquaculture systems and women with lower education levels were convinced that both wild and farmed fish offer benefits and present disadvantages.

Originality/value

The paper shows that attitudes of light fish users are partially similar to heavy fish users considering farmed fish production, with the search for convenience being driven by either perceived lack of time or perceived lack of cookery skills to prepare fish‐based meals.

Abstract

Purpose

The purpose of this paper is to develop a method for the discovery of knowledge in emergency response databases based on police incident reports, generating information that identifies local criminal demands that allow the selection of the appropriate policing strategies portfolio to solve the problem.

Design/methodology/approach

The developed model uses a methodology for the discovery of knowledge involving text mining techniques using Latent Dirichlet Allocation (LDA) integrated with the ELECTRE I multicriteria method.

Findings

The developed method allowed the identification of the most common criminal demands that occurred from January 1 to December 31, 2016, in the policing areas studied. One of the crimes does not occur homogeneously in a particular locality. In this study, it was initially observed that 40 per cent of the crimes identified in the Integrated Public Safety Area 5, or AISP-5, (historical city center of RJ) had no correlation with AISP-19 (Copacabana - RJ), and 33 per cent of crimes crimes in AISP-19 were not identified in AISP-5. This finding guided the second part of the method that sought to identify which portfolio of policing strategies would be most appropriate for the identified demands. In this sense, using the ELECTRE I method, eight different scenarios were constructed where it can be identified that for each specific criminal demand set there is a set of policing strategies to be applied.

Research limitations/implications

The collected data represent the social dynamics of neighbourhoods in the central and southern zones of the city of Rio de Janeiro during the specific period from January 2013 to December 2016. This limitation implies that the results cannot be generalised to areas with different characteristics.

Practical implications

The developed methodology contributes in a complementary way to the identification of criminal practices and their characteristics based on reports of police occurrences stored in emergency response databases. The knowledge generated through the identification of criminal demands allows law enforcement decision makers to evaluate and choose among the available policing strategies, which best suit the reality they study, and produce the reduction of criminal indices.

Social implications

It is possible to infer that by choosing appropriate strategies to combat local crime, the proposed model will increase the population’s sense of safety through an effective reduction in crime.

Originality/value

The originality of the study lies in the integration of text mining techniques, LDA and the ELECTRE I method for detecting crime in a given location based on crime reports stored in emergency response databases, enabling identification and choice, from customized policing strategies to particular criminal demands.

Abstract

Purpose

Because that the crime in a wide way impacts the life of the people in the big metropolis, researchers have treated the question from several angles. The purpose of the paper, under the umbrella of operational research, is to develop a model of the ordering of police strategies, in the fight against crime in general, according to a certain criminal demand.

Design/methodology/approach

For the construction of the impact matrix of the strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria ELECTRE IV method was used, which with the help of the J-Electre software emulated the systematized data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision-makers.

Findings

As a result, the research revealed that policing strategies directed at solving specific crimes are the most effective in the perception of decision-makers after the emulation of data with the ELECTRE IV method.

Research limitations/implications

As research implications, it can be inferred that the use of multicriteria methods in the modeling of problems in the area of public security can contribute to rationalization of the use of the means available in the fight against crime in large cities. The research showed that it is possible to use customized policing strategies to a certain reality.

Practical implications

The method presented in this research is directly related to the major strategies: problem-oriented policing and hot spot policing. This method allows public safety managers to consider the possibility of combining different law enforcement strategies in each context. In this sense, the use of the multiple-criteria decision analysis (MCDA) (ELECTRE IV) method allows the evaluation of a large set of alternatives according to a set of established criteria, speeding up the process and reducing subjectivity, allowing the manager to analyze several scenarios with greater clarity and impartiality and choosing an alternative that best solves the proposed problem. The expected result is the rationalization of the available means applied in the search for the reduction of crime rates.

Social implications

The customization of policing strategies, according to criminal demands, implies the efficient way to reduce criminal charges. Reducing criminal rates enables the development of the local economy, tourism and the quality of life of people by exercising their freedom to the full.

Originality/value

The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices, and in their associated use in ordering strategies through a multicriteria method.

The purpose of this paper is to examine the inter-relations among the US stock indices.

Abstract

Purpose

The purpose of this paper is to examine the inter-relations among the US stock indices.

Design/methodology/approach

Data of nine US stock indices spanning a period of sixteen years (2000-2015) are employed for this purpose. Asymmetries are examined via an error correction model. Non-linear inter-relations are researched via Breitung’s nonlinear cointegration, a M-G nonlinear causality model, shocks to the forecast error variance, a shock spillover index and an asymmetric VAR-GARCH (VAR-ABEKK) approach.

Findings

The inter-relations are significant. The results are robust across all types of inter-relations. They are highest in the Lehman Brothers sub-period. Higher stability after the EU debt crisis, enhances independence and growth for the US stock indices.

Originality/value

To the best of the knowledge, this is the first study to examine the inter-relations of US stock indices. Most studies on inter-relations concentrate on the portfolio analysis to reveal diversification benefits among various asset markets internationally. Hence this study contributes to this literature on the inter-relations of a specific asset market (stock), and in a specific nation (USA). The evident inter-relations support the notion of diversification benefits in the US stock markets.

Abstract

Purpose

Even though the implementation of lean in health care environments is relatively recent, it has been receiving a lot of attention in recent years. Partly because of the fact that it is a recent field of practise and research and partly because the number of works developed in this field has grown rapidly, it is important to frequently update the perspectives on this field of investigation. Thus, this study aims to review the implementation of lean tools and techniques applied to hospital organizational areas in a five-year period, between 2014 and 2018, complementing some of the most relevant reviews already published. The most important criteria such as tools, methods and principles, hospital areas intervened, improvements and difficulties were assessed and quantified.

Design/methodology/approach

As starting point for this systematic literature review (SLR), a set of selected pre-existing review publications was used to support the current study and as the ground base for the expansion of the studies about lean health care. The current study contemplated 114 articles from a five-year period between 2014 and 2018. A subset of 58 of these articles was critically assessed to understand the application of lean tools and methods in different hospital areas.

Findings

The thorough analysis of selected articles show a lack of works in continuous improvement approaches when compared to the application of production organization methods, visual management and diagnosing and problem-solving tools. The reported improvement results demonstrate alignment with the principles and foundations of lean philosophy, but such results are presented in isolated initiatives and without robust evidence of long-term maintenance. Moreover, this study shows an evolution in the number of articles referring to lean implementation in hospital areas, but in its great majority, such articles report isolated implementations in different areas, not spreading those for the global organization. Thus, some of the main recommendations are the need to implement studies on complete flows of patients, drugs and materials, instead of isolated initiatives and strive to promote the cultural change of hospitals through structural changes, following new visions and strategic objectives, supported by real models of continuous structural and sustained improvement.

Originality/value

The current study develops a new perspective of the articles published under the thematic of lean health care, published in a recent period of five years, which are not completely covered by other works. Additionally, it explicitly applied, in an innovative way, an approach that used a set of previous reviews as the starting point for this SLR. In this way, it integrates approaches and categories from different SLRs, creating a framework of analysis that can be used by future researchers. Finally, it shows the most recent implementations of lean health care, exposing the current trends, improvements and also the main gaps.
