The purpose of this paper is to analyse the quality of online information about sexually transmitted diseases (STD) and determine which web sites are suitable for patients to read.

This study evaluated the integrity, accessibility, readability, reliability, and completeness of 75 web sites providing information on one of five different types of STD. The Google AdWords Keywords Tool was used to determine the five most frequently searched STD terms: HIV, herpes, chlamydia, syphilis, and gonorrhoea. These five terms were then subjected to a Google search, and the first 15 web sites found for each term were evaluated. The web sites were assessed for integrity on the basis of a defined integrity score, accessibility on the basis of three levels of conformance to Web Content Accessibility Guidelines, readability on the basis of the Flesch Reading Ease score and the Flesch-Kincaid grade level, reliability on the basis of the LIDA instrument, and completeness on the basis of the quality appraisal instruments developed by the authors.

The results suggested that the quality of information available on different web sites is inconsistent, and the information maintained by government web sites is most appropriate for general public users in terms of integrity, accessibility, readability, reliability, and completeness.

There are currently no studies analysing the quality of online information about STDs.

We study how giving depends on income and luck, and how culture and information about the determinants of others’ income affect this relationship. Our data come from an experiment conducted in two countries, the USA and Spain – each of which have different beliefs about how income inequality arises. We find that when individuals are informed about the determinants of income, there are no cross-cultural differences in giving. When uninformed, however, Americans give less than the Spanish. This difference persists even after controlling for beliefs, personal characteristics, and values.

This paper examines whether short sellers aggravate volatility in the Australian stock market by using five different realized volatility (RV) measures during a more stable period.

The authors develop a measure to capture the abnormal level of short selling for each stock and examine the bivariate and trivariate dynamic relationships between abnormal short selling and five volatility measures: the RV, continuous and jump components of RV, upside and downside volatilities.

Overall, the findings indicate a weak association between abnormal short selling and volatility. Where the relationships are significant, the authors generally find that lagged abnormal short selling is negatively associated with both upside and downside volatilities. In general, short selling does not drive or amplify the decline in stock prices.

This paper contributes to existing literature in various aspects. First, the authors offer evidence on the relationship between abnormal short selling and volatility in a general market condition while existing studies often found mixed results of the effects of short selling on volatility around extreme events. Second, the authors add to the literature on the volume-volatility relation by introducing abnormal short selling. Although abnormal short volume does not supplant the number of trades in the volume-volatility relation, it has some incremental, albeit negative, effect on volatility. Finally, the study provides further evidence for the debate on the desirability of short sellers in financial markets.

Tourism, as a system, develops strategies for risk prevention and mitigation. The shock generated by the COVID-19 pandemic is different when compared with previous events because it is more intense and prone to structural changes. Tourists' perceptions condition their behaviour and decisions, with adverse results on travel and tourism consumption; and hygiene and health risks generate a cause-effect relationship on destination specificities.

From globalisation to risk perception and crisis management, in a framework where technology, communication and digital content represent undeniable importance, we are facing circumstances especially conducive to the redesign of the collective future, where the sustainability of tourism is a collective goal, arising from the right balance between the competitiveness of destinations and climate action.

Given the prospects for the next decade, health and hygiene are structural factors to be considered in decision-making processes. Thus, so the proposed approach contributes to the awareness, by the various stakeholders, of its importance and the need to implement methods and processes compatible with more inclusive and responsible tourism.

The volatile scenario of technological innovation demonstrates the need for risk control processes, in order to ensure its viability. The purpose of this paper is to propose a conceptual framework for risk management in the introduction of new technologies by start-ups, aiming to provide the guidelines for the improvement of this process.

The study comes up with conceptual categories related to risk management in start-ups, mainly based on the NPVR approach. The methodology included two comparative case studies: MercadoPago and GuiaBolso, which had their data collected through interviews with key managers and documents provided by the organizations. Data analysis was based on the Miles et al. (2014) model, whereby data were condensed; data were visualized, and conclusions developed and checked.

Among the main results, there is the proposition of a deductive-inductive matrix for the management of uncertainties and risks in start-ups, which brings elements that provide the calculation of the NPV adjusted for the risk of developing a new product (NPVR), process or service, as well as the contribution of the level of risk management maturity of the companies, setting up the Risk Management Matrix (RMM).

The authors propose a matrix for the management of uncertainties and risks in start-ups.

The authors present comparative case studies of MercadoPago and GuiaBolso which help the entrepreneurs to develop their start-ups.

As the main contribution, this paper proposes the start-up RMM, a model for the management of uncertainties and risks in start-ups, which brings elements that provide the calculation of the NPV adjusted for the risk of developing a new product (NPVR), process or service, as well as the contribution of the level of risk management maturity of the companies.

This study analyses the dimensions of the brand equity of organic agri-food products using a multidimensional approach. It also examines the direct and indirect relationships of this brand equity with consumers’ green satisfaction and the green image of organic agri-food products. The green brand can be understood as a tool for entrepreneurial development.

The researchers develop a conceptual framework highlighting the dimensions of the green brand equity focusing on five constructs (green brand loyalty, green perceived quality, green brand associations, green brand awareness and the new dimension of green brand emotion), green satisfaction and green brand image. The sample consisted of 392 people aged over 18 who were occasional or habitual consumers of organic agri-food products. Partial least squares (PLS), a structural equation modelling (SEM) tool, was used in the analyses.

The results of this study show that the different dimensions of green brand equity (except for green brand awareness) reflect this variable and are important factors in its perception by consumers. This study differs from others in that it treats green brand equity as a truly multidimensional variable made up of different dimensions with different measurement scales. The study also demonstrates the importance of green satisfaction and green brand image as antecedents of green brand equity.

The measurement scale for green brand equity developed in this study provides entrepreneurs of organic agri-foods with a method for evaluating consumer perception of green brand equity based on those dimensions that are truly significant.

This is the first study to explore the relationships of green brand equity—as a multidimensional concept—with other variables, such as green satisfaction and green image.

Globally, urban planners and decision makers are pursuing place-based initiatives to develop and enhance urban infrastructure to optimise city performance, competitiveness and sustainability credentials. New discourses associated with big data, Building Information Modelling, SMART cities, green and biophilic thinking inform research, policy and practice agendas to varying extents. However, these discourses remain relatively isolated as much city planning is still pursued within traditional sectoral silos hindering integration. This research explores new conceptual ground at the Smart – Natural City interface within a safe interdisciplinary opportunity space. Using the city of Birmingham UK as a case study, a methodology was developed championing co-design, integration and social learning to develop a conceptual framework to navigate the challenges and opportunities at the Smart-Natural city interface. An innovation workshop and supplementary interviews drew upon the insights and experiences of 25 experts leading to the identification of five key spaces for the conceptualisation and delivery at the Smart-Natural city interface. At the core is the space for connectivity; surrounded by spaces for visioning, place-making, citizen-led participatorylearning and monitoring.The framework provides a starting point for improved discussions, understandings and negotiations to cover all components of this particular interface. Our results show the importance of using all spaces within shared narratives; moving towards ‘silver-green’ and living infrastructure and developing data in response to identified priorities. Whilst the need for vision has dominated traditional urban planning discourses we have identified the need for improved connectivity as a prerequisite. The use of all 5 characteristics collectively takes forward the literature on socio-ecological-technological relationships and heralds significant potential to inform and improve city governance frameworks, including the benefits of a transferable deliberative and co-design method that generates ownership with a real stake in the outcomes.

The purpose of this paper is to know which hotels mostly rely on Booking.com, investigating the level of presence on Booking.com around the world by country, hotel size, hotel category and managerial form. Neither the company nor the hotels provide this information, so the authors use the number of reviews as an indicator of estimated sales.

Data from 33,996 hotels worldwide are downloaded from Booking.com using a Web browser automatically controlled, developed in Python, that simulated a user navigation (clicks and selections). The comparison between independent hotels and hotels belonging to a chain is performed by a Student’s t distribution test and the comparison of hotel categories and hotel size is analyzed by a one-way ANOVA test.

The results show that three factors clearly influence the usage level of Booking.com: independent vs chain hotels, small vs large hotels and low vs high category hotels worldwide. The authors also observe that hotels from Europe are the ones that rely more on Booking.com.

The originality of this research is to identify the factors that make hotels to have a greater (lesser) dependence on Booking.com within each destination and geographical area. Moreover, the use of big data from hotels worldwide allows the authors to know the level of use of Booking.com in dozens of countries, especially those with the highest tourist activity. This work expands the capabilities of big data in the hospitality industry research, and with a simple ratio, this study counteracts the lack of public data on hotel sales through Booking.com. This new approach could be extended to the analysis of other online travel agencies (OTAs), which use similar review systems.

The rapid adoption of social media has resulted in a fundamental shift in the way communication and collaboration take place. While social media is recognized as an important marketing communication tool, it has become overlooked how social media marketing activities (user-generated and firm-generated content) influence brand equity creation in the higher education sector. Drawing from social identity theory, this study identifies how higher education institutions develop customer-based brand equity using social media marketing and social brand engagement, taking cross-comparison between high and low subjective norms.

A survey was used to collect data from a sample of 936 undergraduates of private higher education institutions in Sri Lanka and Vietnam. These data were gathered using purposive sampling, and in testing the hypothesis and structure among the variables, structural equation modeling was used to determine the relationship between the study variables.

For the conceptual framework, the authors found that the structural equation model complies with the empirical data. The structural equation model shows that social brand engagement mediates the relationship between user-generated content, firm-generated content and brand equity. Further, the subjective norms were found to moderate the relationship between user-generated content, firm-generated content and social brand engagement, highlighting that the lower the subjective norms the higher the influence on social brand engagement as students receive low pressure and influence from external parties.

The study was conducted at private higher education institutes in Sri Lanka and Vietnam. Future research could benefit from the perceptions of undergraduates in public higher education institutes. Future researchers could widen the diversity of service settings in the sample and replicate this investigation to discover if the results are consistent across the whole services sector.

The current research contributes to the services marketing and branding literature in the higher education context. The paper presents the crucial elements in building brand equity for higher education institutes to fill the existing gaps in higher education branding literature. The findings of the current study provide strategies to improve the higher education sector.
