The hygiene factor is always imperative when customers consider a certain restaurant, and the information contained in customer reviews can be an efficient approach to gauge a restaurant's hygiene during gaps in the official inspection. Therefore, the purpose of this study was to investigate whether information obtained from online reviews could predict the upcoming hygiene rating, specifically, evaluating the impact of both qualitative and quantitative content of reviews on the restaurant hygiene rating.

The quantitative research method with big data analytic techniques was applied in this study. In total, 127,656 pieces of data collected from 1,710 restaurants in four major cities in the USA were used in the analysis. Both quantitative factors (i.e. reviewer's numerical rating, days to review, readability, useful/funny/cool) and qualitative factors (i.e. eight emotional dimensions of textual reviews) were analyzed from the online customer reviews and considered in predicting the restaurant's hygiene rating.

Six out of eight emotional dimensions including anger, disgust, fear, sadness, surprise and trust were identified as having significant influences on the restaurant hygiene ratings. While three quantitative variables including days to review, readability and usefulness were identified with significant impacts on the dependent variable of restaurant hygiene rating.

This study opens an avenue for innovative research that establishes a connection between customers' reviews and restaurants' inspection systems. The results allow restaurants to predict an impending hygiene inspection rating upon dynamic assessment of review content and aid in adjusting hygiene measures accordingly.

The purpose of this paper is to present a framework for scholars carrying out reviews of research that meet international standards for publication.

This is primarily a conceptual paper focusing on the methodology of conducting systematic reviews of research. However, the paper draws on a database of reviews of research previously conducted in educational leadership and management. In a separate effort, the author identified 40 reviews of research that had been published in educational leadership conducted over the past five decades. The paper draws upon narrative examples from the empirical review as a means of clarifying and elaborating on the elements of the conceptual framework. The paper also refers to specific findings from the earlier paper in order to illustrate broader trends with respect to how the various elements of the framework have been employed in exemplary reviews.

As scholars working across a broad range of scientific fields suggest, high quality reviews of research represent a potentially powerful means of reducing the gap between research and practice. Yet, the quality of research reviews conducted in educational leadership and management remain highly variable in methodological rigor. This paper provides a conceptual framework and language that scholars might use to guide the conduct and evaluation of future research reviews in educational leadership and management.

The contribution of this paper lies first in highlighting the need for scholars to employ systematic methods when conducting research reviews in educational leadership and management. Beyond this broad purpose, the paper provides a framework for decision‐making at different points in the review process, and a set of criteria or standards by which authors, readers and reviewers can judge the quality of a research review. It is hoped that this conceptual framework can provide useful methodological guidance that will enhance longstanding efforts in our field to advance knowledge in a more systematic and coherent fashion.

This originality of this paper lies in its adaptation and application of recent methodological advances in conducting reviews of research across the natural and social sciences to the field of educational leadership and management. A search of core journals in educational leadership and management found not a single paper that discussed methods of conducting reviews of research. The paper offers a clear framework that will allow future scholars in educational leadership and management to improve the quality of their research reviews.

This study aims to review relevant studies concerning consumer purchase of halal-certified products. A total of 35 studies related to the consumer purchasing behavior of halal-certified products in top-tier journals have been identified according to the recommended systematic literature review methodology.

A systematic literature review approach was implemented to examine, summarize and finally interpret the relevant research stream pertaining to consumer purchase of halal-certified products.

There are five research streams extracted from this systematic review, halal study context, theories adapted, covariance-based-structural equation modeling (SEM) vs partial least square-SEM, Muslim vs nonMuslim consumer and role of religiosity. Despite the growing interest in the quantitative approach in consumer purchase behavior in halal-certified products, scholars in halal consumer studies must have a greater extent of work. These include incorporating diverse theories in the framework, an advanced SEM approach, and relevant determinants to capture consumer purchasing of halal-certified products in the highly anticipated and profitable Muslim market.

Findings would help researchers in halal studies to consider and contemplate critical issues, according to the research stream presented in this review.

To the best of the authors’ knowledge, this study is the first review of quantitative studies on consumer purchases of halal-certified products.

The purposes of this study are to synthesize the current research findings reported in major hospitality and tourism journals and to discuss the knowledge gaps where additional research endeavors are needed.

A systematic review approach was adopted to analyze 67 research articles about online reviews that were published between January 2000 and July 2015 in seven major hospitality and tourism journals.

This study presents a thematic framework of online review research, which was advanced by integrating the interactions among quantitative evaluation features, verbal evaluation features, reputation features and social features of online reviews with important outcomes of consumer decision-making and business performance. The thematic framework helps researchers identify the areas in extant hospitality literature of online reviews and point out possible directions for future studies.

The systematic review approach has a qualitative nature, where relevant literature was interpreted based on the authors’ domain knowledge and expertise.

Practitioners can gain a comprehensive understanding of the dynamic relationships among the key influential factors in online reviews, as presented in the thematic framework of online review research. Accordingly, managers will be able to develop effective strategies to leverage the positive impacts of online reviews to the business outcomes.

This systematic review synthesizes the findings reported in most recent publications (January 2000-July 2015; also including “Online First” articles) in seven major hospitality and tourism journals and develops an integrated research framework, anchoring on four meta-research questions and showing the dynamic relationships among the key players/factors/themes in online review research. This framework provides a visual diagram to practitioners for a better understanding of the relevant literature and assists researchers in developing new research questions for future studies.

This paper examines the status and evolution of green innovation research from 1948 to 2018.

Using a systematic review of 293 peer-reviewed scholarly articles, the authors classify journal outlets, publication trends, research methods (research type, approach, design), themes/topics focus, country and regional distribution and theoretical perspectives, identifying main trends. They apply mixed methodologies, integrating both content and descriptive analyses.

Results reveal the following critical conclusions: (1) publication trends disclose a steady growth of interest in green innovation research in the last decade (2011–2018), with most of the articles appearing in top-ranked journal outlets; (2) empirical studies involving quantitative surveys dominate the field over other methods like experiments, case studies (qualitative) and conceptual models; (3) research themes/topics are multi-perspectives, covering management and strategic dimension of green innovation (e.g. green innovation integration and adoption strategy; collaboration and networking in green innovation; green innovation management systems, green supply chain management, etc.), performance (financial, non-financial and both), drivers/antecedents and consumer green behavior; however, the “management and strategy” papers are by far higher; (4) studies are preponderately multi-country focused, concentrated in Europe and Australasia, with a low concentration in emerging markets like Africa and South America; And (5) the field lacks the adoption and development of novel theories. So far, the research fields principally focus on the “Porter hypothesis” and resource-based view in terms of the theory-driven studies. Based on these findings, knowledge gaps are identified, as are limitations and actionable agenda for future research.

As the first systematic review to adopt a comprehensive, holistic approach in synthesizing and summarizing research vis-à-vis the phenomenon of green innovation, the study offers practitioners and researchers an insightful understanding of the relevant issues that have been investigated on green innovation, thereby anchoring the evolutions for further sustainable-oriented research and improvement in management practices.

This study aims to conduct a critical review of the research on the sharing economy to identify its key intellectual foundations and their evolution and offers thematic and methodological recommendations for future research to advance the domain.

A tri-method approach using bibliometric (co-citation) analysis, thematic content analysis and a quantitative systematic literature review was conducted on sharing economy research in hospitality and tourism journals, up to and including May 2020.

The findings from the three methods were coherent and provide a clear picture of the fact that while research on the sharing economy in hospitality and tourism has achieved significant depth, the breadth of the understanding of this area remains somewhat limited. Each of the three periods of research on the sharing economy identified in the study were marked by a focus on specific thematic areas, with largely Western-situated researchers demonstrating limited theoretical engagement and using a limited range of methods and perspectives (disciplinary, stakeholders and sectors) to examine these themes.

Recommendations for future thematic research opportunities are provided using a multi-level perspective. The present review does not include research that incorporates the impacts of COVID-19, which has significantly disrupted the hospitality and tourism industry and is the focus of current research in the field. However, the review represents the largest and most comprehensive assessment of the state of research on the sharing economy prior to COVID-19, and, as such, can serve as a valuable baseline for future reviews of sharing economy research during and after the pandemic.

In contrast with previous literature reviews, the present review is comprehensive in its scope, methodology and temporal coverage of sharing economy research. It also examines the evolution of research on the topic, enabling a more nuanced identification of gaps and future thematic and methodological research opportunities.

This paper presents a systematic review of 94 research articles in the domain of gender and firm innovation to map the area and infer future research avenues. The literature captured in this review includes seven theoretical, 16 qualitative and 71 quantitative studies from over 50 journals, examining the role of gender in firm innovation in over 100 countries.

This research utilises a reproducible systematic literature review process to identify prominent theoretical and empirical studies.

The findings suggest that the area is growing and presents interesting opportunities. However, it is observed that empirical investigations are primarily influenced by literature from the Anglo-Saxon areas and give little attention to contextual intricacies of emerging market countries. Among quantitative studies, three main themes of gender are addressed unevenly. They are Top Management Team (TMT) diversity level, R&D team diversity level and individual entrepreneur level studies. Six interesting research avenues are proposed as a major outcome of the review.

This review is one of the first of its kind to extensively review the literature of gender and firm-level innovation. The review consolidates and widens the understanding of the relationship between gender variables and firm innovation-related variables to advance the discussion in the domain by presenting research gaps and questions gleaned from the articles. To this end, the review presents six promising research avenues in the area of gender and firm innovation.

The emergence of social media has provided an alternative mechanism for students to provide and access online reviews about universities. These forms of feedback are often not systematically monitored and interpreted by universities. The purpose of this paper is to analyse quantitative ratings and qualitative comments provided by students via Google reviews of 40 Australian universities. The qualitative comments were analysed via thematic coding which identified four key themes including quality of teaching, course design, learning environment and administrative support. The data were also subjected to automated content analysis using the text analytics software Leximancer to enhance the objectivity and reliability of findings.

The study involved the extraction of quantitative ratings as well as qualitative comments from Google reviews of 40 Australian universities. Each university was searched on Google and their rating and comments were collected as of August 2019. The qualitative data were included in an Excel spreadsheet along with the name of the universities, and their quantitative ratings. Using thematic coding techniques, the qualitative data were manually coded into four themes: quality of teaching, course design, learning environment and administrative support. Furthermore, the qualitative comments were grouped into two categories: positive comments and negative comments.

The paper argues the need for universities to actively monitor these new forms of student feedback which have provided autonomy and freedom for students and other stakeholders to access and provide 24/7 feedback. The study found common themes emerging from the positive and negative student comments related to: quality of teaching, course design, learning environments and administrative support. These aspects contributed to the students’ satisfaction levels when they reflected on their educational experience on Google reviews. The study also found that institutions with high numbers of negative comments tend to have lower ratings compared to those with positive comments.

The study did not use other learning analytic tools to measure and assess the feedback from students using social media and other forms of feedback.

Many studies have been undertaken on student experience. Studies have focussed on the experience of home and international students, on-campus and online students, and students from various underrepresented backgrounds. So far no study has been undertaken on the reviews provided by students using Google reviews.

This study aims to analyze review research in hospitality, identifying the structure and most recent developments in current hospitality review studies while providing exploratory insights for future research in this research area.

Using bibliometric analysis, content analysis and a quantitative systematic literature review, this study provides a comprehensive review and critical analysis of 128 review studies published in leading hospitality journals (International Journal of Contemporary Hospitality Management, International Journal of Hospitality Management and Journal of Hospitality Marketing and Management).

This paper presents a comprehensive and in-depth discussion based on the title, journal source, author contribution, year of publication, sample size, selected period, database selection, methodology, data collection methods, themes, regional selection, keywords, abstracts and results of the hospitality review studies analyzed. The findings provide new insights to advance the theoretical and practical implications of review studies in hospitality.

This research provides critical insights for both hospitality review studies and academic and industry hospitality personnel.

As a pioneering study in research on review studies, the results of this paper focus not only on a systematic overview and assessment of recent hospitality review works but also on the future agenda of hospitality and review studies.

The purpose of this paper is to investigate employees’ perception of their organization and to examine the impact of such perception on overall employee satisfaction using qualitative and quantitative employee reviews in an online platform.

The employee online reviews were classified into positive and negative sentiments using sentiment analysis. Further, multiple regression was employed to examine the impact of sentiments (positive and negative) and employee ratings on pre-defined job attributes in explaining overall employee satisfaction with the organization.

The findings of the sentiment analysis shows that employee online reviews exhibit more positive sentiments than negative sentiments. Positive sentiments show a significant positive effect, and negative sentiments show a significant inverse relationship with overall employee satisfaction. Further, pre-defined job attributes are differently related to overall employee satisfaction with the organization, skill development being the strongest predictor.

Practitioners may customize the organization's policies and practices based on the sentiments associated with employee reviews. Organizations emphasizing employee engagement and satisfaction are suggested to include skill development as their priority.

Most existing work on overall employee satisfaction is primarily based on the survey questionnaire method; only recently, online employee reviews (OERs) are gaining attention. The current research uses employee online reviews to study overall employee satisfaction.
