User-generated reviews and the financial performance of restaurants
Authors: Abdullah Saddam , Van Cauwenberge Philippe , Vander Bauwhede Heidi , O'Connor Peter 
Published: May 2022

PurposeThis paper aims to examine the impact of selected characteristics (rating, volume and variability) of online user-generated reviews on the bottom-line profitability of restaurants.Design/methodology/approachRestaurant-level review data are extracted from TripAdvisor and matched with firm-level data from the financial reports gathered from the Belfirst database of Bureau van Dijk. The resulting sample contains data on 2,297 Belgian firms over the period 2007–2018, for which 134,831 reviews are investigated. The author’s regression model of firm-level profitability is estimated against online review characteristics and various financial control variables, including past profitability. This research model and estimation technique address the endogeneity concerns that typically weaken this kind of study.FindingsWhile comparable studies on hotels document a positive association between review characteristics and profitability, the authors find no relationship between review rating, volume and variability in the profitability of restaurants.Research limitations/implicationsDue to the format of the financial reports of small and medium-sized enterprises (SMEs), data on turnover and cost of materials/services was not available for most restaurants in the sample, limiting our potential for analysis. In addition, our assessment of electronic word of mouth (eWOM) was limited to measures derived from user-generated reviews on TripAdvisor.Practical implicationsIn the literature on eWOM, the importance of online reputation is hardly disputed, especially in the context of the hospitality sector. However, most research to date has focused on the hotel sector and top-line measures of success. This study uses restaurant-level financial data, focuses on bottom-line profitability, considers potential endogeneity issues and pays careful attention to the estimation technique. The results fail to establish a direct relationship between eWOM metrics and financial performance and are surprising, meriting further investigation to establish the underlying causes.Originality/valueIn contrast to prior studies on the impact of eWOM on restaurant performance at a group level, this study examines the impact on unit-level profitability, taking into account several potential sources of estimation bias. In addition, the authors challenge this finding with a battery of sensitivity tests, revalidating the absence of a relationship in each case.
Perceived price and trustworthiness of online reviews: different levels of promotion and customer type
Authors: Pan Huifeng , Liu Zhiqiang , Ha Hong-Youl 
Published: May 2022

Purpose
Prior hospitality studies have reviewed review trustworthiness and perceived price as predictors of restaurant selection. However, the impacts of these two factors may vary by sales promotion and customer types. This study aims to determine whether sales promotions and customer type are the key elements that facilitate behavioral intentions by moderating the linkage between perceived price and behavioral intentions as well as the linkage between online review trustworthiness and behavioral intentions.

Design/methodology/approach
Analysis of the responses of 533 individuals familiar with the Michelin Guide for restaurants in Seoul provided evidence supporting a sales promotion theory wherein promotions signal benefits in consumers’ minds.

Findings
The findings show that when perceived price is positive and the trustworthiness of online reviews is high, repeat customers prefer mixed coupons to price discounts. Notably, the results indicate that when the trustworthiness of online reviews is high, first-time customers also prefer mixed coupons to price discounts. Furthermore, the findings suggest that negative evaluations of perceived price increase the impact of mixed coupons by signaling to first-time customers that given restaurants’ offerings provide monetary benefits regardless of their intentions to revisit said restaurants.

Research limitations/implications
The study findings provide insights that should help managers better understand various levels of promotion. Managers can design their pricing strategies to strengthen customers’ motivations to visit their restaurants – the very thing customers often seek in sales promotions.

Originality/value
This study provides indisputable evidence for a sales promotion theory, wherein promotions signal benefits in consumers’ minds; however, it also shows that first-time and repeat customers do not respond equally to sales promotions.
Do Islamic microfinance institutions affect the socio-economic development of the beneficiaries? The evidence from Turkey
Authors: Ülev Salih , Savaşan Fatih , Özdemir Mücahit 
Published: May 2022

Purpose
This paper aims to investigate the effect of Islamic microfinance on poor households through the case of the IKSAR Qard al-Hasan Program in Turkey. To achieve this aim, it examined the changes in the socio-economic status of beneficiaries before and after the program.

Design/methodology/approach
This paper adopts the convergent parallel mixed method design. It conducted two surveys to micro-entrepreneurs: the first is when they received the loan and the second is when they finished their installments. In addition to the longitudinal data obtained from these two surveys, qualitative data were collected by participant observation and interview technique with visiting these people periodically throughout the interest-free loan (qard al-hasan).

Findings
According to the results obtained from the analysis of the pre- and post-surveys, a statistically significant increase of 35% was experienced in the monthly household income after receiving the qard al-hasan loan compared to before. Similarly, a statistically significant increase was found in the monthly expenditures of 23 out of 30 households after receiving the qard al-hasan.

Originality/value
There are two originalities of this study. To the best of the authors’ knowledge, it is the first research that examines the only Islamic microfinance program in Turkey. Second, it uses longitudinal data while examining the impact of Islamic microfinance on the welfare of the poor. In the relevant literature, no study has been identified that uses longitudinal data in Islamic microfinance. Similarly, a limited number of longitudinal studies examine the impact of conventional microfinance institutions on the poor.
What if the local community is already well-off enough? Stakeholders’ conflicts over sustainable tourism development in remote communities
Authors: Elgammal Islam 
Published: May 2022

Purpose
This study aims to explore community involvement in sustainable tourism development (STD) at Siwa Oasis, Egypt, and examines the perspectives of local communities, visitors and governmental decision makers concerning the area’s STD plans. It provides a brief discussion on the stakeholders’ conflict of interest alongside exploring the costs and benefits of STDs for the community. This study examines the area’s problems and challenges and expands the discussion on STD by providing a deep understanding of the oasis context, which involves a broad range of issues.

Design/methodology/approach
In this exploratory study, 18 semi-structured interviews were conducted with three groups of stakeholders (local community, governmental decision makers and visitors) to investigate the current practices of STD and the future vision for the area. Data were coded and interpreted using thematic analysis.

Findings
This paper provides empirical insights into how STDs can be practised in an oasis context. It suggests there is a conflict between the governmental vision for the area and the community’s needs that could lead to a failure to implement STDs. Themes related to environmental, social and economic STD dimensions are discussed. The findings provide managerial and practical implications for decision makers on the promotion of STDs in remote communities.

Research limitations/implications
Because of the chosen research approach, the results may lack generalizability. Therefore, future studies are encouraged to test the study’s propositions further by using a mixed-methods approach, particularly during the COVID-19 pandemic.

Practical implications
This paper has implications for STD within an oasis context, particularly concerning balancing the economic, environmental, political and social aspects of STD.

Originality/value
This paper fulfils an identified need to study how STD can be practised when most of the local community is already comparatively well-off economically.

Authors: Lokhtina Irina A. , Colombo Laura , Amelia Citra , Löfström Erika , Tammeleht Anu , Sala-Bubare Anna , Jazvac-Martek Marian , Castelló Montserrat , McAlpine Lynn 
Published: May 2022

PurposeThe study aims to explore and explain the affordances and constraints of two-mode virtual collaboration as experienced by a newly forming international research team.Design/methodology/approachThis is self-reflective and action-oriented research on the affordances and constraints of two-mode virtual collaboration. In the spirit of professional development, the authors (nine researchers at different career stages and from various counties) engaged in a joint endeavour to evaluate the affordances and constraints of virtual collaborations in light of the recent literature while also researching the authors' own virtual collaboration during this evaluative task (mid-January–April 2021). The authors used two modes: synchronous (Zoom) and asynchronous (emails) to communicate on the literature exploration and recorded reactions and emotional responses towards existing affordances and constraints through a collective journal.FindingsThe results suggest both affordances in terms of communication being negotiable and evolving and constraints, particularly in forming new relations given tools that may not be equally accessible to all. Journaling during collaborations could be a valuable tool, especially for virtual collective work, because it can be used to structure the team supported negotiation and discussion processes, especially often hidden processes. It is evident that the role of a leader can contribute to an alignment in the assumptions and experiences of trust and consequently foster greater mutual understanding of the circumstances for productive team collaborations.Originality/valueThe findings of this study can inform academics and practitioners on how to create and facilitate better opportunities for collaboration in virtual teams as a rapidly emerging form of technology-supported working.
Sustainability, non-financial, integrated, and value reporting (extended external reporting): a conceptual framework and an agenda for future research
Authors: de Villiers Charl , Hsiao Pei-Chi Kelly , Zambon Stefano , Magnaghi Elisabetta 
Published: May 2022

Purpose
This paper aims to develop a conceptual framework for extended external reporting (EER) influences (EERI), including sustainability, non-financial, integrated and value reporting. Using the Environmental Legitimacy, Accountability, and Proactivity (ELAP) framework as the base, we modify its proposed concepts and linkages using relevant conceptual models, prior reviews and findings of recent studies on EER. This paper presents contributions of the special issue on “non-financial and integrated reporting, governance and value creation” and avenues for future research.

Design/methodology/approach
Drawing on relevant conceptual models, prior reviews and recent EER studies, we reframed the ELAP framework into a framework that theorises the factors that affects, or are affected by, EER.

Findings
The EERI framework poses relationships between and within proactivity, external verification, accountability and legitimacy. It also consolidates possible determinants and consequences of EER. The papers published in this special issue contribute further insights on factors that influence reporting practices, processes and suggestions for capturing and communicating value creation information, and the value of integrated reports and assurance to capital providers.

Originality/value
Along with the insights provided by papers in this special issue, the conceptual framework can be used to theorise influences of EER and guide future research.
Mood Lifters: evaluation of a novel peer-led mental wellness program
Authors: Votta Cecilia M. , Deldin Patricia J. 
Published: May 2022

Purpose
The purpose of this paper is to test a mental wellness intervention, Mood Lifters (ML), that addresses significant barriers to mental health care. ML includes adults over 18 struggling with mental wellness or any life difficulties, except those with active suicidality, mania and psychosis, and addresses barriers to care using peer leaders in a manualized group format with a gamified point system.

Design/methodology/approach
Participants were recruited using online postings. Those eligible (76% female, 80% white) were randomly assigned to professional-led groups (N = 30), peer-led groups (N = 33) or a waitlist (N = 22; i.e. attended assigned condition if available). Participants completed pre- and postgroup measures (including the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 and Perceived Stress Scale), attended 15 weekly meetings and tracked “points” or at-home skills practice. Multiple imputation was used to account for attrition. Linear regressions were analyzed to determine the program’s impact on anxiety and depressive symptoms and perceived stress. Further analyses included comparisons between peer- and professional-led groups.

Findings
Participants in ML experienced significant reductions in anxiety symptoms. Completing more homework across the program led to significant reductions in anxiety and perceived stress. Finally, there were no significant differences in attendance, homework completed or outcomes between peer- and professional-led groups.

Practical implications
Overall, participation in the ML program led to reduced anxiety symptoms, and for those who completed more homework, reduced perceived stress. More accessible programs can make a significant impact on symptoms and are critical to address the overburdened care system. Additionally, there were no differences between leader types indicating that peers may be an effective way to address accessibility concerns.

Originality/value
ML is unique for three reasons: it takes a biopsychosocial/Research Domain Criteria approach to mental wellness (i.e. incorporates many areas relevant to mental health, does not focus on a specific diagnosis), overcomes major barriers to mental health care and uses a peer-delivery model. These attributes, taken together with the results of this study, present a care alternative for those with less access.
Investigating the effect of habitat amount and landscape heterogeneity on the gamma functional diversity of grassland and hedgerow plants
Authors: Lecoq Lucie , Mony Cendrine , Saiz Hugo , Marsot Myriam , Ernoult Aude 
Published: May 2022

Abstract

Landscape structure is one of the main drivers of biodiversity, especially in agricultural landscapes. However, only a few studies explored its effect on the gamma functional diversity of plants. Yet, research questions at this scale are important to better understand and effectively preserve biodiversity.

Using a large‐scale sampling design with 30 landscape windows, we investigated the effects of habitat amount (i.e. grassland and hedgerow amounts), compositional heterogeneity (i.e. land use diversity) and configurational heterogeneity (i.e. land use spatial complexity) on the gamma functional diversity of plants in two habitat types: hedgerows and grasslands. We also investigated the same effects on the contribution of each functional trait related to different stages of the plant regeneration cycle to the overall functional diversity of plants.

Habitat amount had contrasted effects on the functional diversity of both habitat types: a negative effect on grassland plant assemblages and a positive effect on hedgerow plant assemblages. Landscape heterogeneity only affected the functional diversity of hedgerow plants: configurational heterogeneity favoured functional dispersion but reduced functional evenness, and compositional heterogeneity affected trait contribution especially by shifting phenological and establishment strategies. Because they are linear habitats, hedgerows are indeed more likely to be influenced by edge effects than grasslands and thus displayed a strong response to landscape heterogeneity. Landscape variables influenced all stage of regeneration, and especially had a strong effect on traits related to establishment and dispersal.

Synthesis. We demonstrated that landscape structure can both affect functional diversity and select particular trait syndromes related to plant dispersal, phenology and competitiveness. These results are important because they highlight that functional diversity must be studied at the gamma scale, to better understand the effects of land management and to preserve more effectively the associated ecosystem functioning.
Rootstock–scion combination contributes to shape diversity and composition of microbial communities associated with grapevine root system
Authors: Marasco Ramona , Alturkey Hend , Fusi Marco , Brandi Michele , Ghiglieno Isabella , Valenti Leonardo , Daffonchio Daniele 
Published: May 2022

SummaryTo alleviate biotic and abiotic stresses and enhance fruit yield, many crops are cultivated in the form of grafted plants, in which the shoot (scion) and root (rootstock) systems of different species are joined together. Because (i) the plant species determines the microbial recruitment from the soil to the root and (ii) both scion and rootstock impact the physiology, morphology and biochemistry of the grafted plant, it can be expected that their different combinations should affect the recruitment and assembly of plant microbiome. To test our hypothesis, we investigated at a field scale the bacterial and fungal communities associated with the root system of seven grapevine rootstock–scion combinations cultivated across 10 different vineyards. Following the soil type, which resulted in the main determinant of the grapevine root microbial community diversity, the rootstock–scion combination resulted more important than the two components taken alone. Notably, the microbiome differences among the rootstock–scion combinations were mainly dictated by the changes in the relative abundance of microbiome members rather than by their presence/absence. These results reveal that the microbiome of grafted grapevine root systems is largely influenced by the combination of rootstock and scion, which affects the microbial diversity uptaken from soil.
Queens Consort, Gender and Diplomacy: Catherine of Aragon, Claude of France and the Field of Cloth of Gold
Authors: Fisher Sally 
Published: May 2022

AbstractIn 1520, two queens consort, Catherine of Aragon and Claude of France, attended the event now known as the Field of Cloth of Gold. This article analyses representations of their involvement across three sources; contemporary diplomatic correspondence and two later sources, Edward Hall's Chronicle (1548 and 1550) and the Hampton Court Palace painting of the Field (c. 1545). It examines how the producers of these sources shaped the function of the consort according to their own motivations, genre and the context of their own time. It argues that each source acknowledges the consorts as important to the event's success, but that while contemporary letters represent Catherine and Claude as individuals, the later sources exhibit shifting narratives to focus on the trope of ideal queenship. A similar shift was not apparent for kingship. This comparison of contemporary and later depictions of the consorts reveals a gendered reshaping of their role at the Field across time according to the needs of the creators which, in turn, sheds light on understandings of queenship and diplomatic engagement in early modern England.
A systematic review of the qualitative literature on barriers to high‐quality prenatal and postpartum care among low‐income women
Authors: Bellerose Meghan , Rodriguez Mariela , Vivier Patrick M. 
Published: May 2022

AbstractObjectiveTo examine the qualitative literature on low‐income women's perspectives on the barriers to high‐quality prenatal and postpartum care.Data Sources and Study SettingWe performed searches in PubMed, Web of Science, Embase, SocIndex, and CINAHL for peer‐reviewed studies published between 1990 and 2021.Study DesignA systematic review of qualitative studies with participants who were currently pregnant or had delivered within the past 2 years and identified as low‐income at delivery.Data Collection/Extraction MethodsTwo reviewers independently assessed studies for inclusion, evaluated study quality, and extracted information on study design and themes.Principal FindingsWe identified 34 studies that met inclusion criteria, including 23 focused on prenatal care, 6 on postpartum care, and 5 on both. The most frequently mentioned barriers to prenatal and postpartum care were structural. These included delays in gaining pregnancy‐related Medicaid coverage, challenges finding providers who would accept Medicaid, lack of provider continuity, transportation and childcare hurdles, and legal system concerns. Individual‐level factors, such as lack of awareness of pregnancy, denial of pregnancy, limited support, conflicting priorities, and indifference to pregnancy, also interfered with the timely use of prenatal and postpartum care. For those who accessed care, experiences of dismissal, discrimination, and disrespect related to race, insurance status, age, substance use, and language were common.ConclusionsOver a period of 30 years, qualitative studies have identified consistent structural and individual barriers to high‐quality prenatal and postpartum care. Medicaid policy changes, including expanding presumptive eligibility, increased reimbursement rates for pregnancy services, payment for birth doula support, and extension of postpartum coverage, may help overcome these challenges.

SummaryBifidobacterium bifidum possesses two extracellular sialidases (SiaBb1 and SiaBb2) that release free sialic acid from mucin sialoglycans, which can be utilized via cross‐feeding by Bifidobacterium breve that, otherwise, is prevented from utilizing this nutrient source. Modification of sialic acids with O‐acetyl esters is known to protect mucin glycans from degradation by bacterial sialidases. Compared to SiaBb2, SiaBb1 has an additional O‐acetylesterase (Est) domain. We aimed to elucidate the role of the SiaBb1 Est domain from B. bifidum in sialic acid cross‐feeding within Bifidobacterium. Pre‐treatment of mucin secreted from bovine submaxillary glands (BSM) using His6‐tagged‐Est and ‐SiaBb2 released a higher amount of sialic acid compared to the pre‐treatment by His6‐SiaBb2. Growth of B. breve increased with an increase in nanE expression when supplemented with both His6‐Est‐ and His6‐SiaBb2‐treated BSM. These results indicate that the esterase activity of the SiaBb1 Est domain enhances the efficiency of SiaBb2 to cleave sialic acid from mucin. This free sialic acid can be utilized by coexisting sialic acid scavenging B. breve via cross‐feeding. Here, we provide the molecular mechanism underlying the unique sialoglycan degradation property of B. bifidum which is mediated by the complementary activities of SiaBb1 and SiaBb2 in the context of sialic acid cross‐feeding.
