One of the insidious effects of government and business imposter scams is the potential erosion of trust among defrauded consumers. This study aims to assess the relationship between prior imposter scam victimization and present ability to discriminate between real and fake digital communications from government agencies and retail companies.

This paper tests whether a short, interactive training can help consumers correctly identify imposter scams without mistrusting legitimate communications. Participants were randomized into one of two control groups or to one of two training conditions: written tips on identifying digital imposter scams, or an interactive fraud detection training program. Participants were tested on their ability to correctly label emails, websites and letters as real or a scam.

This paper find that prior imposter scam victimization is not associated with greater mistrust. Compared to the control conditions, both written tips and interactive digital fraud detection training improved identification of real communications and scams; however, after a two- to three-week delay, the effect of training decreases for scam detection.

Results indicate that prior imposter scam victimization is not associated with mistrust, and that one-time fraud detection training improves consumers’ detection of imposter scams but has limited long-term effectiveness.

This study investigates the relationship between CEO leadership, gender homophily and corporate environmental, social and governance (ESG) performance. We also investigate whether it is essential to have a critical mass of women directors on the board to create a significant power of gender diversity in leadership positions.

Our study is based on firms listed on the London Stock Exchange (FTSE-All-Share) from 2011 to 2019. CEO characteristics and other board variables were collected from BoardEx, and ESG data, and other related variables were collected from Eikon database.

We find a critical mass of female directors contributes to ESG performance suggesting that token representation of female directors on boards limits their effectiveness. We do not find support for the gender homophily perspective, our findings suggest that the effectiveness of female CEOs does not depend on the existence of a critical mass of female directors. Female directors and female CEOs are less likely to be associated with ESG activities when firms experience poor financial performance. We also find that younger female CEOs have a positive impact on ESG performance. Furthermore, we find female CEOs with shorter tenure are more likely to improve ESG performance. Overall, our findings suggest a substitutional effect between having female CEOs and gender diverse boards.

This study contributes to the debate on gender homophily in the boardroom and how that may affect ESG practices. It also complements existing academic research on female leadership and ESG performance and has important implications for senior management and policymakers.

This study aims to investigate whether gender diversity in audit committees affects the purchase of nonaudit services in China. Results from family and nonfamily firms are compared and the critical mass participation of females are further examined.

The sample comprises 1,834 Chinese listed companies from 2012 to 2021, among which 910 are family firms. The Heckman (1979) two-stage model is used to mitigate the potential endogeneity issue in the selection of gender diversity. Propensity score matching is also used to further alleviate the endogeneity problem in relation to family firms.

Results show a significant and negative correlation between the gender diversity in audit committees and nonaudit service fees. This association is more apparent in nonfamily than in family firms. Findings are consistent and robust to endogeneity tests and sensitivity analyses. The analysis of critical mass and symbolic participation shows that three female directors can more significantly restrain nonaudit fees than one to two females on the board.

This study contributes to literature on resource dependence theory, which posits that audit committees help enterprises establish contact with auditors, improve the company legitimacy, assist in communication and provide relevant expertise. This study also relates to agency theory, which holds that differences in the severity of types I and II agency problems between family and nonfamily firms lead to differences in auditor selection and related costs.

Extending from previous research on the relation between the gender diversity in audit committees and nonaudit fees, the present study delves into this connection within the context of China, an emerging economy. As a result, this investigation offers novel insights and expands upon current knowledge. In addition, the correlation between the gender diversity of audit committees and nonaudit fees is explored for family and nonfamily firms.

Content analysis was used to measure corporate social responsibility (CSR) reporting. The ordinary least squares (OLS) regressions with robust standard errors are used to examine the relationships for a sample of 168 firm-year observations listed on the Palestine Exchange during 2018–2021. A logistic regression is also utilized as an alternative measurement for CSR quantity disclosure and to ensure the robustness of the author’s main findings.

Based on 168 observations listed on the Palestine Exchange (PEX) between 2018 and 2021, this study examines the impact of women's representation on the CSR reporting of Palestinian firms' boards. Moreover, the moderating effect of ownership concentration on the relationship between BGD and CSR reporting is examined. In order to test the hypotheses, the author’s employ OLS regressions with robust standard errors. A logistic regression is also utilized as an alternative measurement for CSR quantity disclosure and to ensure the robustness of the author’s main findings.

The results reveal that Palestinian companies with more women on their boards have higher CSR practices and disclosure levels. In addition to the validity of agency, stakeholder and legitimacy theories, the findings show the relevance of gender socialization and critical mass theories in explaining the favorable influence of women's presentation on boards in promoting best practices among Palestinian firms, such as CSR disclosure.

The study contributes to the limited literature in the MENA and Arab region countries by examining the influence of BGD on CSR reporting in Palestine, an emerging economy characterized by highly political and economic instability. The study offers a novel contribution by examining the impact of BGD, on not only the CSR reporting quantity but also the reporting quality. However, the generalizability of the study is limited due to the small sample size.

The findings of the study may bring the issues of CSR disclosure and female representation on board of directors to the attention of Palestinian firms' board of directors and managers, investors, professional associations, policymakers and regulators. While listed firms are only required to provide general information that falls under the scope of CSR in their annual reports under the Palestinian code of corporate governance, women representation on boards of directors is not addressed.

This study adds to the very limited literature on the role of the BGD in promoting CSR reporting in the Middle Eastern and Arabic markets in general, and in the Palestinian context in particular. This paper not only investigates but also seeks to theorize this role.

Low-carbon concrete represents a new direction in mitigating the global warming effects caused by clinker manufacturing. Utilizing Saudi agro-industrial by-products as an alternative to cement is a key support in reducing clinker production and promoting innovation in infrastructure and circular economy concepts, toward decarbonization in the construction industry. The use of fly ash (FA) as a cement alternative has been researched and proven effective in enhancing the durability of FA-based concrete, especially at lower replacement levels. However, at higher replacement levels, a noticeable impediment in mechanical strength indicators limits the use of this material.

In this study, low-carbon concrete mixes were designed by replacing 50% of the cement with FA. Varying ratios of nano-sized glass powder (4 and 6% of cement weight) were used as nanomaterial additives to enhance the mechanical properties and durability of the designed concrete. In addition, a 10% of the mixing water was replaced with EMs dosage.

The results obtained showed a significant positive impact on resistance and durability properties when replacing 10% of the mixing water with effective microorganisms (EMs) broth and incorporating nanomaterial additives. The optimal mix ratios were those designed with 10% EMs and 4–6% nano-sized glass powder additives. However, it can be concluded that advancements in eco-friendly concrete additive technologies have made significant contributions to the development of sophisticated concrete varieties.

This study focused at developing nanomaterial additives from Saudi industrial wastes and at presenting a cost-effective and feasible solution for enhancing the properties of FA-based concrete. It has also been found that the inclusion of EMs contributes effectively to enhancing the concrete's resistance properties.

This study aims to understand the dynamics of Australian boards by focusing on the influence of board gender diversity on firms' cash holdings, within the distinctive Australian “if not, why not” regulatory framework.

The study uses ordinary least squares (OLS), fixed effects, generalized method of moments (GMM) and quasi-experimental methods such as difference-in-differences and propensity score matching to analyze the data.

There is a significantly negative relationship between board gender diversity and corporate cash holdings. This relationship is more pronounced when two or more female directors are on the board, supporting the critical mass theory. The results also reveal that the observed pattern can be attributed to the heightened monitoring intensity of female independent directors. Our quasi-experimental methods and pre-post analysis reveal that the observed effects are genuinely attributable to the increase in board gender diversity following regulatory reforms in Australia.

The findings provide practical insights for companies and policymakers, emphasizing the tangible effects of gender diversity on a company's financial strategy and corporate cash holdings. This information is crucial for organizations aiming to make informed decisions regarding board compositions and governance structures.

This research offers fresh insights into an important relationship between gender diversity on boards and corporate financial strategies in the Australian context, enriching the global conversation on the significance of gender diversity in corporate leadership.

A risk-based method is proposed to identify the dominant influencing factors of secondary lining cracking in an operating mountain tunnel with weak surrounding rock.

Based on the inspection data from a mountain tunnel in Southwest China, a lognormal proportional hazard model is established to describe the statistical distribution of secondary lining cracks. Then, the model parameters are obtained by using the Bayesian regression method, and the importance of influencing factors can be sorted based on the absolute values of the parameters.

The results show that the order of importance of the influencing factors of secondary lining cracks is as follows: location of the crack on the tunnel profile, rock mass grade of the surrounding rock, time to completion of the secondary lining, and void behind the secondary lining. Accordingly, the location of the crack on the tunnel profile and rock mass grade of the surrounding rock are the two most important influencing factors of secondary lining cracks in the investigated mountain tunnel, and appropriate maintenance measures should be focused on these two aspects.

This study provides a general and effective reference for identifying the dominant influencing factors of secondary lining cracks to guide the targeted maintenance in mountain tunnels.

This study aims to examine whether information asymmetry (IA) mediates the relationship between women directors and the cost of equity (COE). Specifically, this study posits that women directors tend to lower the COE through the channel of IA.

This study uses the US-listed firms’ data from 2002 to 2014, comprising 11,189 firm-year observations. This study measures the COE by aggregating the four unique market-based COE models and apply pooled ordinary least square to estimate our results.

This study documents that women directors are linked to IA, and that IA is linked to the COE. Furthermore, in the mediation test, IA fully mediates the relationship between women directors and the COE. This study's results also validate the critical mass hypothesis, as the IA shows full mediation between the critical mass of women directors and COE. This study also discusses the limitations and major implications of the results along with possible future directions.

This study also supports the positive role of females in improvising the economic performance of the firms and supporting the sustainable development goals-5 (gender equality).

The originality of this study lies in its theoretical as well as empirical contributions. First, this study follows the line of inquiry of the mediation analysis, thereby contributing by examining whether the relationship between women directors and financial value, i.e. COE, is indirect. Second, in addition to ex post measures of the COE, this study used four ex ante unique market-based models to measure the COE. Most of the prior studies just rely on book-based measures or use a single market-based mode. Third, the findings contribute insights into how women directors add value and benefits firms.

In this paper, the complex flow evaporation process of droplet impact on the liquid film in a horizontal falling film evaporator is numerically studied based on smoothed particle hydrodynamics (SPH) method. The purpose of this paper is to present the mechanism of the water treatment problem of the falling film evaporation for the high salinity mine water in Xinjiang region of China.

To effectively characterize the phase transition problem, the particle splitting and merging techniques are introduced. And the particle absorbing layer is proposed to improve the nonphysical aggregation phenomenon caused by the continuous splitting of gas phase particles. The multiresolution model and the artificial viscosity are adopted.

The SPH model is validated qualitatively with experiment results and then applied to the evaporation of the droplet impact on the liquid film. It is shown that the larger single droplet initial velocity and the smaller single droplet initial temperature difference between the droplet and liquid film improve the liquid film evaporation. The heat transfer effect of a single droplet is preferable to that of multiple droplets.

A multiphase SPH model for evaporation after the droplet impact on the liquid film is developed and validated. The effects of different factors on liquid film evaporation, including single droplet initial velocity, single droplet initial temperature and multiple droplets are investigated.

Ecotourism has emerged as a new hope of the tourism sector and is expected to overcome past pitfalls of mass tourism. Therefore, the purpose of this paper is to assess the potentials and challenges of ecotourism development in the historic and sacred sites of North Shewa Zone, Ethiopia.

Data were collected through interview, household questionnaire, field observation and focused group discussion. The collected data were analyzed using Statistical Package for Social Science (SPSS version 23) and Excel.

Based on household’s perception, churches and monasteries were mentioned as the main (17.58%) ecotourism attractions that have crucial role in ecotourism development in the area followed by biodiversity resources (17.23%) and Holy Water (16.01%). These existing ecotourism potentials and opportunities were discussed on the basis of five dimensions, i.e. historical and sacred attractions, biological attractions, cultural attractions, infrastructures and institutional potentials. The mean score values of a five-point Likert scale level of agreement or disagreement of respondents were between 2 and 4.5, implying overall responses of respondents spread between agree and strongly agree.

The findings reveal that although the historic and sacred sites of the area have potential ecotourism opportunities, different anthropogenic activities are affecting its development. The researchers recommended awareness creation programs, promotion of sites, development of infrastructures, employments of well-trained professionals and allocation of sufficient budgets as a mechanism to use the ecotourism potential and solving the existing challenges.
