Abstract
There is an urgency to build a critical view of information and communication technologies in society and education in order to harness their pedagogical potential. Generally, the Covid-19 pandemic demanded transformation, which is one of the possibilities in times of crisis. Despite the pandemic exposing digital exclusion in many parts of the planet, digital technologies concurrently have overcome, at least in part, social isolation through the provision of remote activities. The functionality of technologies motivated the question that guides the present investigation: how does the use of technologies before, during, and after the pandemic period appear in the products of the ISATT academic community? The objective is to come to know the contribution of ISATT and the degree to which its input is current and relevant. To meet our goal, we conducted an exploratory study gathering data by means of Google Form questionnaire. ISATT members invited to answer the questionnaire were also participants in the survey. Our intent is to map and describe the relationship between technology and creative teaching and categorize the different approaches used. Our analysis will allow ISATT community members to evaluate their interests, foci, trends, and contributions.

Abstract
Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals face an elevated level of prejudice in various social settings like sports. These biases can relate to internalized stigma, which might prompt LGBTQ+ athletes to implement numerous identity coping strategies. Muslim LGBTQ+ athletes are likely to experience these dynamics more than others. However, there remains a dearth of scholarship on understanding how Muslim LGBTQ+ athletes employ different identity development coping strategies to tackle the prevalent stigma against them and use their visible identity development process as a means of social activism. Hence, in this book chapter, the authors explore the development of Muslim LGBTQ+ sportspersons' visible identity by defining the forces that shape their identity. The first author of the book chapter sheds light on his experiences while working with the LGBTQ+ community in the Islamic Republic of Pakistan and his recent interactions with the Muslim LGBTQ+ community in North America. The authors then highlight how Muslim LGBTQ+ athletes might use different identity coping strategies to show personal agency against the heteronormative system. Furthermore, the authors elucidate how sexual orientation intersects with religion within the sociocultural domain in shaping the identity and present global Muslim LGBTQ+ identity typology. Finally, the authors argue that Muslim LGBTQ+ athletes' visible identity depends upon two factors: religious negative/positive self-beliefs about religion Islam's openness toward LGBTQ+ rights and social acceptance, bounded by time and space.

Abstract
Purpose
Ohmic heating generates temperature with the help of electrical current and resists the flow of electricity. Also, it generates heat rapidly and uniformly in the liquid matrix. Electrically conducting biofluid flows with Ohmic heating have many biomedical and industrial applications. The purpose of this study is to provide the significance of the effects of Ohmic heating and viscous dissipation on electrically conducting Casson nanofluid flow driven by peristaltic pumping through a vertical porous channel.
Design/methodology/approach
In this analysis, the non-Newtonian properties of fluid will be characterized by the Casson fluid model. The long wavelength approach reduces the complexity of the governing system of coupled partial differential equations with non-linear components. Using a regular perturbation approach, the solutions for the flow quantities are established. The fascinating and essential characteristics of flow parameters such as the thermal Grashof number, nanoparticle Grashof number, magnetic parameter, Brinkmann number, permeability parameter, Reynolds number, Casson fluid parameter, thermophoresis parameter and Brownian movement parameter on the convective peristaltic pumping are presented and thoroughly addressed. Furthermore, the phenomenon of trapping is illustrated visually.
Findings
The findings indicate that intensifying the permeability and Casson fluid parameters boosts the temperature distribution. It is observed that the velocity profile is elevated by enhancing the thermal Grashof number and perturbation parameter, whereas it reduces as a function of the magnetic parameter and Reynolds number. Moreover, trapped bolus size upsurges for greater values of nanoparticle Grashof number and magnetic parameter.
Originality/value
There are some interesting studies in the literature to explain the nature of the peristaltic flow of non-Newtonian nanofluids under various assumptions. It is observed that there is no study in the literature as investigated in this paper.

Abstract
Purpose
This study aims to analyze the Prandtl fluid flow in the presence of better mass diffusion and heat conduction models. By taking into account a linearly bidirectional stretchable sheet, flow is produced. Heat generation effect, thermal radiation, variable thermal conductivity, variable diffusion coefficient and Cattaneo–Christov double diffusion models are used to evaluate thermal and concentration diffusions.
Design/methodology/approach
The governing partial differential equations (PDEs) have been made simpler using a boundary layer method. Strong nonlinear ordinary differential equations (ODEs) relate to appropriate non-dimensional similarity variables. The optimal homotopy analysis technique is used to develop solution.
Findings
Graphs analyze the impact of many relevant factors on temperature and concentration. The physical parameters, such as mass and heat transfer rates at the wall and surface drag coefficients, are also displayed and explained.
Originality/value
The reported work discusses the contribution of generalized flux models to note their impact on heat and mass transport.

Abstract
Purpose
The purpose of this study is to investigate whether customers perceive current cruise ship safety measures provided as meeting a sense of security and their influence on purchase intention. Three types of potential risks associated with cruise lines evaluated were external/internal attacks, malfunctions/accidents and onboard medical/health issues.
Design/methodology/approach
A survey used 12 safety measures questions to examine how cruise ships handle the above three risks, three questions to measure a sense of security and three questions to measure purchase intention. A seven-point Likert scale was applied. Convenience sampling was used. There were 163 valid responses collected.
Findings
All three safety measures evaluated in this study had a direct and positive effect on passengers' Sense of Security. Also, Safety Measure (SM) 2 and Sense of Security had direct and positive effects on purchase intention. Finally, SM1 and SM3 have only indirect impacts on Purchase Intentions via Sense of Security.
Research limitations/implications
Because of the small sample size and the convenience sampling method, the results of this study may lack generalizability.
Practical implications
Cruise managers should be aware that merely providing safety measures that are regulated by guidelines is not sufficient, and passengers must personally see and experience safety measures.
Originality/value
This study evaluated not only customers’ perceptions of safety measures on a cruise ship but also their impact on a sense of security and how that played a moderating role in purchase intention.

This study aims to examine the moderating effect of cultural conditions on the relationship between environmental performance and environmental disclosure.
Abstract
Purpose
This study aims to examine the moderating effect of cultural conditions on the relationship between environmental performance and environmental disclosure.
Design/methodology/approach
The authors used meta-analysis technique to examine 100 effect sizes from 43 studies published between 1982 and 2023 to integrate the existing results and to detect causes contributing to variability of results across studies.
Findings
There is a significant positive relationship between environmental performance and environmental disclosure. Further, the authors found that cultures with long-term orientation positively moderated the relationship, whereas cultures with high uncertainty avoidance and indulgence negatively moderated it.
Research limitations/implications
This study did not account for the problem of endogeneity between environmental performance and environmental disclosure because most of the already published studies included in the authors’ meta-analysis did not address this issue.
Practical implications
This research provides regulators and policymakers insights on the influence of cultural factors on environmental disclosure and performance, critical information to consider when adopting, or revising social and environmental policy and regulations within a country.
Originality/value
To the best of the authors’ knowledge, this is the first meta-analysis study examining different cultural dimensions influencing the relationship between environmental performance and environmental disclosure and contributes new knowledge to the literature on determinants of environmental disclosure.

Abstract
Purpose
This paper aims to explore the double diffusive magneto-hydrodynamic (MHD) squeezed flow of (Cu–water) nanofluid between two analogous plates filled with Darcy porous material in existence of chemical reaction and external magnetic field.
Design/methodology/approach
The governing nonlinear equations are transformed into ordinary differential equations by means of similarity transforms, and the coupled mass and heat transference equations are resolved analytically with the application of differential transform method (DTM). The effects of different relevant parameters on velocity, temperature and concentration, including the squeeze number, magnetic parameter, Biot number, Darcy number and chemical reaction parameter, are illustrated with figures. In addition, for various parameters, the local skin friction coefficient, local Nusselt number and local Sherwood number are computed and are graphically displayed.
Findings
It is observed that the squeeze number has a direct relationship with Sherwood number and an inverse relationship with skin friction as Biot number increases. With enhanced Biot numbers, the temperature value increases during both squeeze and non-squeeze moments, but the temperature values are higher for squeeze moments compared to the other case.
Practical implications
This research has potential applications in various large-scale enterprises that might benefit from increased productivity.
Social implications
The results are useful to thermal science community.
Originality/value
Unique and valuable insights are provided by studying the impact of chemical reaction on double diffusive MHD squeezing copper–water nanofluid flow between parallel plates filled with porous medium. In addition, this research has potential applications in various large-scale enterprises that might benefit from increased productivity.

Abstract
Purpose
The purpose of this paper is to articulate the results of a comprehensive literature review and grassroots outreach with first responder organizations to present an operationalized framework for organizations to utilize as a blueprint in developing customized behavioral health access program (BHAP) programs.
Design/methodology/approach
Historically, authorities having jurisdiction (AHJ)over fire service organizations have primarily offered behavioral health interventions through Employee Assistance Programs (EAPs) or commercial insurance carriers. These programs are necessary but may prove insufficient to meet the scope and needs of trauma-exposed firefighters and the firefighters' families.
Findings
A BHAP is a comprehensive and operationalized plan which clearly specifies the mental health services fire department members and families need, where those services are available within their communities and levels and standards of care that are expected in the provision of these services.
Originality/value
The BHAP is becoming a world standard of behavioral health care for first responders. While some fire service agencies are beginning to create BHAP guides, developing and implementing a BHAP can be time consuming and overwhelming, particularly for departments with limited internal and external resources. While the results of this review focus on BHAP within the fire service, this framework is applicable across all first responder professions.
