This chapter provides an overview on the traditions and values of teaching students with traumatic brain injury (TBI). First, we discuss the prevalence, identification, and characteristics associated with TBI and how those characteristics affect learning, behavior, and daily life functioning. Next, we focus on instructional and behavioral interventions used in maintaining the traditions in classrooms for working with students with TBI. Findings from a review of the literature conclude that there are no specific academic curriculums designed specifically for teaching students with TBI; however, direct instruction and strategy instruction have been shown to be effective educational interventions. Current research on students with TBI is predominately being conducted in medical centers and clinics focusing on area of impairments (e.g., memory, attention, processing speed) rather than academic achievement and classroom interventions. Finally, we conclude with a list of accommodations and a discussion of recommendations for future work in teaching students with TBI.

This study compared different types of full-time caregiver (e.g., children, older adults, COVID-19 patients) and subgroups (e.g., disability, race/ethnicity, sexual orientation) in the United States during the COVID-19 pandemic for potentially meaningful distinctions.

Data from the 9,854 full-time caregivers identified in Phase 3.2 (July 21–October 11, 2021) of the US Census Household Pulse Survey (HPS) were analyzed in this study using multinomial logistic regression to examine relationships between caregiver types, marginalized subgroups, generation, and vaccination status.

The prevalence of caregiving was low, but the type of full-time caregiving performed varied by demographic group (i.e., disability, race/ethnicity, sexual orientation, gender, generation, and vaccination status). The relative risk of being a COVID-19 caregiver remained significant for being a member of each of the marginalized groups examined after all adjustments.

To date, the HPS has not been analyzed to predict the type of full-time informal caregiving performed during the COVID-19 pandemic or their characteristics. Research limitations of this analysis include the cross-sectional, experimental dataset employed, as well as some variable measurement issues.

Prior informal caregiver research has often focused on the experiences of those caring for older adults or children with special healthcare needs. It may be instructive to learn whether and how informal caregivers excluded from paid employment during infectious disease outbreaks vary in meaningful ways from those engaged in other full-time caregiving. Because COVID-19 magnified equity concerns, examining demographic differences may also facilitate customization of pathways to post-caregiving workforce integration.

The particle distribution in a fluid is mostly not homogeneous. The inhomogeneous dispersion of solid particles affects the velocity profile as well as the heat transfer of fluid. This study aims to highlight the effects of varying density of particles in a fluid. The fluid flows through a wavy curved passage under an applied magnetic field. Heat transfer is discussed with variable thermal conductivity.

The mathematical model of the problem consists of coupled differential equations, simplified using stream functions. The results of the time flow rate for fluid and solid granules have been derived numerically.

The fluid and dust particle velocity profiles are being presented graphically to analyze the effects of density of solid particles, magnetohydrodynamics, curvature and slip parameters. Heat transfer analysis is also performed for magnetic parameter, density of dust particles, variable thermal conductivity, slip parameter and curvature. As the number of particles in the fluid increases, heat conduction becomes slow through the fluid. Increase in temperature distribution is noticed as variable thermal conductivity parameter grows. The discussion of variable thermal conductivity is of great concern as many biological treatments and optimization of thermal energy storage system’s performance require precise measurement of a heat transfer fluid’s thermal conductivity.

This study of heat transfer with inhomogeneous distribution of the particles in a fluid has not yet been reported.

The purpose of this study is to investigate the effects of entropy generation of some embedded thermophysical properties on heat and mass transfer of pulsatile flow of non-Newtonian nanofluid flows between two porous parallel plates in the presence of Lorentz force are taken into account in this research.

The governing partial differential equations (PDEs) were nondimensionalized using suitable nondimensional quantities to transform the PDEs into a system of coupled nonlinear PDEs. The resulting equations are solved using the spectral relaxation method due to the effectiveness and accuracy of the method. The obtained velocity and temperature profiles are used to compute the entropy generation rate and Bejan number. The influence of various flow parameters on the velocity, temperature, entropy generation rate and Bejan number are discussed graphically.

The results indicate that the energy losses can be minimized in the system by choosing appropriate values for pertinent parameters; when thermal conductivity is increasing, this leads to the depreciation of entropy generation, and while this increment in thermal conductivity appreciates the Bejan number, the Eckert number on entropy generation and Bejan number, the graph shows that each time of increase in Eckert will lead to rising of entropy generation while this increase shows a reduction in Bejan number. To shed more light, these results were further demonstrated graphically. The current research was very well supported by prior literature works.

All results are presented graphically, and the results in this article are anticipated to be helpful in the area of engineering.

This paper aims to examine whether the audit committee moderates the relationship between audit quality and market reactions.

Using fixed effects and the GMM model for robustness, the study used 472 publicly listed firms on South Africa’s Johannesburg stock exchange spanning a period of six years from 2014 to 2019.

Results obtained show that audit quality impacts market reactions through share price and adjusted market returns. And, that the audit committee moderates the relationship between audit quality and market reactions in South Africa’s publicly listed firms. An effective audit committee is expected to play a crucial role in overseeing the audit process, ensuring the independence of auditors and promoting transparency and accountability which in turn impacts asset prices.

The study implies that governments and regulatory bodies in other developing economies could strengthen regulations about companies’ Acts, how firms regulate themselves and more so audit committees. Firms can also strive to make sure that audit committees are staffed with experts to promote higher audit quality and investor attention to get access to the much-alluded capital.

To the best of the authors’ knowledge, the study adds value by being the first to explore the subject matter of the importance of audit committees in defining audit quality and market reactions in publicly listed firms. The research adds to the body of knowledge on corporate governance and audit quality. It provides a case study specific to the South African context, contributing to the global literature on these topics.

Political dissent threads through the history of the Olympic Games. Although the International Olympic Committee (IOC) openly prohibits athletes from injecting politics into the Games, Olympians have nevertheless staged protests, using the Olympics to challenge the predominant power structures and institutions. This chapter analyzes outbursts of athlete activism in the context of wider social movements that make these political paroxysms more viable. Social movements scythe political space for athletes, spark athletes' political imaginary, and provide support and cover. From the early days of the Games, Olympic athletes have expressed dissent, as when Irish track-and-field athlete Peter O'Connor rebelled against British colonialism at the 1906 Olympics in Athens. At the Mexico City 1968 Games, Czech gymnast Vera Čáslavská carried out a politically symbolic acts as did US sprinters John Carlos, Tommie Smith, and Wyomia Tyus. At the 1972 Munich Games, US track medalists Vincent Matthews and Wayne Collett protested in nonchalant fashion on the medal stand. At the 1980 Olympics, Polish Olympian Władysław Kozakiewicz issued politically provocative symbology on the pole vault mat that challenged Soviet hegemony. In the twenty-first century, numerous Olympians have made political statements, despite a rule in the Olympic Charter that forbids such activity. In each case, athlete activists were bolstered by vibrant political movements in their home country. In this chapter, I trace the relationship between political Olympians and social movements as well as the wider dialectic of resistance and restriction that encompasses the interplay between dissident Olympians and the IOC.

The education of deaf and hard of hearing (d/DHH) students is largely dependent on the preferred mode of communication. Historically, the mode of communication for d/DHH students was determined by society rather than by students and families. This resulted in divisiveness between the Deaf culture and proponents of oral communication. The adoption of IDEA allowed family participation in the decision-making process. Advances in technology increased student access to sound, resulting in more educational placement options. Despite the positive changes, the complex nature of hearing loss and the wide variety in cultural considerations have made it difficult to determine the best approach to deaf education. Thus, educators and providers are left in a conundrum of which version of “traditional” deaf education is best for students.

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.

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.

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.

The reported work discusses the contribution of generalized flux models to note their impact on heat and mass transport.

Economy-wide crises create major challenges for small and medium enterprises (SMEs). Existing studies emphasize the crucial role of contrasting behavioral strategies, effectuation and causation in SMEs' adaptation to crisis conditions. Yet, prior literature concentrated predominantly on exploring the impact of effectuation and causation on firm performance rather than survival. The authors present and empirically test a theoretical model explaining how behavioral strategies affect SME survival during an economy-wide crisis under different levels of environmental dynamism.

The authors propose a theoretical framework based on the combination of the effectuation literature and the emerging variance-based perspective on entrepreneurial actions. The theoretical model is then tested using a sample of Russian SMEs during a period of economic adversity and recovery (2015–2019).

The empirical results reveal that causation reduces the probability of firm survival in dynamic environments, while effectuation increases the chance of survival irrespective of the state of the environment. In a nutshell, the study provides evidence that the effectuation logic serves a viable way for SMEs to increase the chances of survival through the economic shock and subsequent recovery period.

For the first time in the literature, the authors demonstrate the role of behavioral strategy (effectual and causal) as a crucial antecedent of SME survival in the short and medium term, particularly during an economy-wide downturn. Furthermore, the study demonstrates the power of variability-based theorizing for explaining and predicting the survival/failure implications of entrepreneurial actions.

This paper explores some of the gaps and contradictions that can often be found in public sector leader development approaches and then examines some of the theoretical assumptions related to these gaps and contradictions. The purpose of this examination is to further identify and define some corresponding gaps within public sector leadership development theory, as well as to encourage future theory development.

Using three common examples of contradictions often found within the leadership literature, gaps within public sector leadership development theory are identified and then linked to relevant components of leader development models found within other disciplines. As they were developed in other contexts, these components were then further reviewed to determine their potential applicability in speaking to the gaps often found in public sector leader development theory.

Proposals are made to address some of the common gaps and contradictions often identified in some public sector leader development approaches, along with the detailing of future research directions for the further development of theory.

This exploratory review highlights some of the central assumptions and gaps in the literature for the purpose of clarifying future directions of research into public sector leadership development theory.
