Abstract
Purpose
This study aims to examine the cilia-driven flow of magnetohydrodynamics (MHD) non-Newtonian fluid through a porous medium. The Jeffrey fluid model is taken into account. The fluid motion in a two-dimensional symmetric channel emphasizes the dominance of viscous properties over inertial properties in the context of long wavelength and low Reynolds number approximations.
Design/methodology/approach
An integrated numerical and analytic results are obtained by hybrid approach. A statistical method analysis of variance along with response surface methodology is used. Sensitivity analysis is used to validate the accuracy of nondimensional numbers.
Findings
The impact of various flow parameters is presented graphically and in numerical tables. It is noted that the velocity slip parameter is the most sensitive flow parameter in velocity and relaxation to retardation time ratio in temperature.
Originality/value
A model on cilia-generated flow of MHD non-Newtonian Jeffrey fluid is proposed.

Abstract
Purpose
To investigate whether individuals more closely associate characteristics of effective leaders with men compared to women and whether those associations advantage men in interactions.
Methodology/approach
An online survey and a laboratory experiment. The online survey had participants evaluate characteristics they most closely associated with effective leaders, men in general, or women in general. The laboratory experiment assigned participants fictitious partners before they completed an ambiguous task. Partners were men or women, and instructions did or did not describe contrast sensitivity ability as related to leadership ability.
Findings
In Study 1, participants evaluated characteristics of men in general more closely to the characteristics of effective leaders than they did the characteristics of women in general. Findings showed this effect to be driven by responses from male participants. In Study 2, the influence gap between male and female partners widened significantly in a direction that advantaged men when study instructions described contrast sensitivity as being positively correlated with leadership ability.
Implications
Individuals associate characteristics of effective leadership in ways that advantage men and that those associations advantage men in interactions.
Social Implications
Results indicate that even if differences in competency expectations between women and men were to disappear, women might remain disadvantaged in interactions with implications for leadership.
Originality/Value of Paper
The paper conclusively demonstrates that participants in the samples associated men more than women with leadership ability/effectiveness and that the associations advantaged men in interactions. These results have broad implications for research in status, gender, and leadership.

Abstract
Purpose
Recent scholarship calls for identifying conditions in which procedurally just treatment translate to increased police legitimacy. The present study draws on community justice and vitality and procedural justice literature to examine whether adolescent and young adults’ perceptions of legitimate work and school opportunities in their neighborhoods moderate the effects of fair treatment by police on perceptions of police legitimacy.
Design/methodology/approach
Longitudinal data from a justice-involved youth sample and a series of generalized linear mixed models are used to test the study’s hypotheses. We model “persons as contexts” and separate within-person and between-person effects.
Findings
Main effects models indicate that procedural justice and neighborhood opportunities both have significant within-individual, between-individual and person-contextual effects on police legitimacy. Results from interaction models indicate strong support for a person-contextual interaction effect. Net of covariates, higher average perceptions of procedurally just treatment leads to greater average police legitimacy, but this effect erodes when individuals perceive weak educational and occupational opportunities in their neighborhoods over time.
Originality/value
Efforts to maximize police legitimacy may be enhanced through greater investment in community opportunity structures. This study highlights the need for public officials and police to support the educational and occupational vitality of communities as a key strategy to promote police legitimacy and optimize core aspects of the procedural justice model.

Abstract
Generally, dark tourism is considered an area of segment currently being developed within the tourism industry due to its sudden popularity. Dark tourism is related to death, disaster, tragedy, and suffering. Nevertheless, the association has yet to be thoroughly researched. Thus, this study investigates the relationship between the marketing strategies employed in the dark tourism industry. This study explores the cinema or short web series/TV serials on dark tourism. In addition, the current development in entertainment media and the sudden rise of streaming platforms, social media, iCloud, content marketing, virtual influences, and bloggers in dark tourism play a pivotal role in this era. Thus, this study will investigate the relationship between these roles in dark tourism. The noticeable findings of this research are also to understand further roles within the marketing strategies that further affect dark tourism. Secondary data were explored to achieve the purpose of the study. This study has contributed to the body of knowledge regarding dark tourism and marketing strategies by providing in-depth information that will benefit scholars, tourism planners, and policymakers.

Abstract
Purpose
This research focuses on the controlling irreversibilities in a radiative, chemically reactive electromagnetohydrodynamics (EMHD) flow of a nanofluid toward a stagnation point. Key considerations include the presence of Ohmic dissipation, linear thermal radiation, second-order chemical reaction with the multiple slips. With these factors, this study aims to provide insights for practical applications where thermal management and energy efficiency are paramount.
Design/methodology/approach
Lie group transformation is used to revert the leading partial differential equations into nonlinear ODE form. Hence, the solutions are attained analytically through differential transformation method-Padé and numerically using the Runge–Kutta–Fehlberg method with shooting procedure, to ensure the precise and reliable determination of the solution. This dual approach highlights the robustness and versatility of the methods.
Findings
The system’s entropy generation is enhanced by incrementing the magnetic field parameter (M), while the electric field (E) and velocity slip parameters (ξ) control its growth. Mass transportation irreversibility and the Bejan number (Be) are significantly increased by the chemical reaction rate (Cr). In addition, there is a boost in the rate of heat transportation by 3.66% while 0.05⩽ξ⩽0.2; meanwhile for 0.2⩽ξ⩽1.1, the rate of mass transportation gets enhanced by 12.87%.
Originality/value
This paper presents a novel approach to analyzing the entropy optimization in a radiative, chemically reactive EMHD nanofluid flow near a stagnation point. Moreover, this research represents a significant advancement in the application of analytical techniques, complemented by numerical approaches to study boundary layer equations.

Abstract
Purpose
This paper examines the relationship between open innovation (measured by exploratory and exploitative linkages) and firm-level innovative activity in the offshore renewable energy (ORE) sector.
Design/methodology/approach
A unique, purpose-built survey that targeted firms operating in the ORE sector and its supply chain was used. The data provides novel insights into the research activities and networking capabilities of an industry in its infant stages of development. Regression models are used to estimate the relationship between firm-level external linkages and innovative activity.
Findings
Exploratory linkages are positively related to more innovative activity. This relationship is subject to diminishing returns, distinguishing the ORE sector from other sectors. Collaborating with suppliers and accessing scientific journals are conducive to research and development (R&D) activity and process innovation, whilst collaborating with customers is associated with the decision to introduce new products and processes.
Originality/value
This study provides evidence of a positive, but curvilinear, relationship between external knowledge linkages and innovative activity, adding novel insights into the relationship between open innovation (OI) strategies, research and innovation outcomes for firms predominantly in the introductory stages of the technological life cycle with limited commercialisation experience. The nuanced finding that specific linkages matter for certain research and innovation (R&I) outcomes adds deeper complexity to March’s (1991) framework, where tailoring certain exploratory or exploitative linkages to specific innovation activities is important.

Abstract
Purpose
This study examines conditions under which taxes and subsidies designed to mitigate corporate environmental impact positively influence corporate pro-environmental behavior (CPEB) adoption, considering unique dynamics within different industries.
Design/methodology/approach
A systematic literature review was conducted on 171 articles. Articles were coded using an inductive grid for comprehensive examination.
Findings
Taxes generally positively influence CPEB adoption, but reduced positive or even negative effects can arise. Subsidies, while often facilitating the achievement of environmental goals, variously impact CPEB. Explanations for variations include the level of taxation or subsidy, economic agent affected, subsidy source, nature of subsidy, factors external to tax or subsidy characteristics and conflicting environmental objectives. We suggest research avenues for each aspect, to enhance literature on the influence of tax policies on promoting CPEB.
Practical implications
Beyond general tax-policy considerations, we provide policymakers with recommendations for tax policies designed to promote CPEB.
Originality/value
We examine the distinctive effects of taxes and subsidies on CPEB adoption within diverse industries ((re)manufacturing, agriculture, shipping, automobile, freight transport and power generation). We compare specific effects across industries, and advocate detailed exploration of recurrent elements identified, emphasizing their potential significance in designing taxes and subsidies that promote CPEB.

Abstract
Purpose
This paper shows how a small jurisdiction can apply well-designed non-conviction-based (NCB) forfeiture provisions with a dedicated team to have a meaningful impact on financial crime. This paper aims to examine developing jurisprudence, legislation and case law to explore how the NCB laws work. Finally, this paper examines a relatively new area of law for Canada, unexplained wealth orders (UWOs). This paper discussed three recent cases in Western Canada currently before the courts.
Design/methodology/approach
This paper considers legislative and jurisprudential developments relevant to NCB or civil asset forfeiture and in particular considers very recent developments involving UWOs.
Findings
This paper shows how a small jurisdiction can apply well-designed NCB forfeiture provisions with a dedicated team to have a meaningful impact on financial crime.
Research limitations/implications
Some jurisdictions, like the UK, have experienced court losses with their UWO process. Canadian law may have a modest pathway to success in this area, although our jurisprudence is very much in development.
Practical implications
Manitoba is a small jurisdiction with limited resources who are finding ways to have an effective impact on financial crime through the careful application of use of conviction-based forfeiture.
Social implications
Financial crime has an outsized impact on society. This paper shows some of the techniques available to disrupt financial crime.
Originality/value
This paper incorporates developments in 2024 that have not yet been examined.

Abstract
Purpose
This study aims to examine the impact of firm-level corporate social responsibility (CSR) governance characteristics on the extent, quality and comprehensiveness of CSR reporting of Pakistani listed enterprises.
Design/methodology/approach
This study used content analysis of corporate annual reports and stand-alone CSR reports available on corporate websites in 2021 to identify CSR-related governance features and to calculate CSR reporting scores. Multivariate regression is used to test relationships. In addition, the analysis tested the moderating role of profitability in these relationships.
Findings
Firm-level CSR governance characteristics contribute to the extent, quality and comprehensiveness of CSR reporting in a developing country. Further, results confirm that profitability moderates the relationship between CSR governance and the extent and comprehensiveness of CSR reporting.
Research limitations/implications
This study employed cross-sectional data and focused on a single developing country. Future studies might include a cross-national sample and longitudinal data to demonstrate the broader relevance of these findings. The outcomes of this study are restricted to CSR disclosures based on CSR reports and annual reports. Future research may examine additional corporate communication channels, such as websites and social media platforms.
Practical implications
This research validates the important role of CSR governance mechanisms as a driver of comprehensive CSR reporting. Business leaders and policymakers can facilitate improved corporate reporting by requiring companies to implement CSR-related governance mechanisms.
Originality/value
This is the first study to test the influence of firm-level CSR governance mechanisms in promoting the quantity, quality and comprehensiveness of CSR reporting in a developing country.
