This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL⁻¹ h⁻¹. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

Because of growing corporate tax scandals, there is an enhanced focus on corporate taxation by governments, institutions and the general public. Transparency in tax matters has been identified as critical for effectively managing and promoting socially responsible tax behaviour. This study aims to explore the impact of ownership structure, board and audit committee characteristics on corporate tax responsibility (CTR) disclosure.

This research collected data from the annual reports of Pakistani-listed firms over 12 years, from 2009 to 2020. Consequently, the data set encompasses a total of 1,800 firm-year observations. This study uses regression analysis to test the relationship between corporate governance and CTR disclosure.

The results show that board gender diversity, managerial ownership and audit committee independence promote tax responsibility disclosure. In contrast, family board membership, CEO duality, foreign ownership and family ownership negatively impact tax responsibility disclosure. Additional analyses reveal the specific information categories that produce the overall effects on tax responsibility disclosure and assess the moderating impact of family firms on the governance and CTR disclosure nexus.

Corporations can use the results to encourage practices that enhance transparency and improve the quality of disclosures. Regulatory authorities can use the findings to stipulate better protocols. Doing so will be vital for developing countries such as Pakistan to improve tax revenue and cultivate economic growth.

While this research represents, to the best of the authors’ knowledge, one of the first empirical investigations of the association between corporate governance and CTR, the results contribute to the corporate governance literature and offer fresh insights into CTR, an emerging dimension of corporate social responsibility.

The authors focus on using Critical Race Theory (CRT) as a lens through which to analyze the holistic welfare development of Black male student-athletes, namely their identity development and overall college and career readiness. The authors contend that if structured and delivered well with the appropriate supports, athletics can be more of a mobilizing mechanism for Black males versus an exploitive one. Specifically, athletic identity does not have to be exclusive, but rather one aspect of the student-athletes' multidimensional sense of self. To this end, the authors outline specific research, practice, and policy recommendations that address the unique challenges of Black male student-athletes in K-16.

Limited research investigates the travel behavior of the retired adult population before retirement and how it changes after retirement. Currently, most of the travel research on the retired population explores their current travel patterns in retirement. Increased research on travel activity before retirement would allow managers in the tourism industry to better adapt and anticipate the changing needs and demographics of seniors, notably, the various ways this growing population manages travel and specific barriers or concerns they face. The authors examined the changes to the travel patterns – defined as travel frequency, mode of transportation, and geographic location/s (domestic or international) – of those retired traveling before and after retirement. Since retirement is a time of major life change, the authors analyzed how this event impacts travel behavior. This research identified barriers these Baby Boomers and those who are retired experience while traveling, including health, social activities, and financial status, which may impact their travel, the degree to which their travel behavior is affected, and specific environmental and personal factors impacting their travel patterns. This chapter will explore the barriers and motivations to travel for the retired population. Results show that before retirement seniors had less time to travel, obligations at home, and were not interested in as many destinations. After retirement, health barriers negatively impacted an individual’s travel frequency and they were also more concerned about safety while traveling and accessibility to the destinations. After retirement, financial barriers impacted an individual’s domestic travel frequency, with those having lower incomes traveling less. Accessibility to the destination facility and transportation options were major barriers to traveling internationally. Before and after retirement, there was a decrease of 10 percent in international travel.

The purpose of this study is to identify discourses of sustainability of community colleges and how they related to sustainability imaginaries.

This study used a combination of research strategies associated with corpus linguistics and critical discourse analysis. Data included 57 issues of Community College Journal, a professional magazine published by the American Association of Community Colleges, and 2,972 abstracts of dissertations about community colleges. Publication dates ranged from 2010 to 2020.

Community college discourse of sustainability coheres around six themes: careers and fields of study; curriculum and credentialing; campus ecological sustainability; administrative roles and processes; external organizations, partnerships and processes; and fiscal sustainability. There is little evidence of a sustainable living imaginary found.

The analysis is limited to a specific set of professional and academic texts about community colleges. Future researchers should explore discourses of sustainability in other contexts.

There has been no research associated with critical discourse analysis and corpus linguistics to explore community college discourses of sustainability, specifically in the field of community college leadership. The findings of this study situate the community college within contests over sustainability competencies in the practice of community college leadership development.

The transition to college presents significant challenges for many students as they navigate new academic and social experiences. In the USA, 30% of first-year students drop out before their second year. Research indicates that mentoring programs help students achieve social integration and likely have a positive effect on their transition to college. This research study was conducted with education students to better understand the potential impacts of peer mentorship.

Student mentors and mentees were matched by attributes such as their concentration within the education major, gender, sports they played and whether they were first-generation matriculants. Data collection utilized two surveys one before the peer mentoring process and one after the process.

The findings suggest that peer mentoring improved first-generation students' sense of belonging to both their major and the college. Peer mentors also experienced increased belongingness. The transfer rate among participants of 2% was a significant drop from previous years.

The success of the peer mentoring experience was possibly due to the intentional matching process based on certain attributes. Additionally, taking a leadership role increased a sense of belonging in the peer mentors.

Work–nonwork policies and practices provide support for employee well-being, as well as a competitive advantage that can help differentiate organizations. However, not all work–nonwork policies and practices are effective, utilized, or relevant. In this chapter, the authors introduce “organizational boundary management strategy” as a way to leverage these policies and practices, making them more widely adopted and more effective. Organizational boundary management strategy refers to how an organization as a whole tends to support workers’ work–nonwork boundaries (i.e., via segmentation, integration, or somewhere in between). Although boundary management has historically tended to focus on how individuals navigate distinctions between work and personal life, the authors extend boundary management to the organization to suggest how understanding and aligning the organization’s overall boundary management strategies can support worker well-being. To expound on this, the authors present a model suggesting how organizational boundary management can be used to support worker well-being.

The involvement of stakeholders such as employers, alumni, and students has always been considered a key element in improving the higher education (HE) system. While considering stakeholders as key players in serving the market and in improving HE instruction, a two-sided collaborative involvement should aim at satisfying the mutual interests and overcoming existing barriers. Quality assurance systems have always supported crossing these barriers to link with the external stakeholders. However, many of the external quality assurance agencies (EQA) in the Middle East and North Africa (MENA) region specify a group of external holders, limiting the various types of key stakeholders needed to enhance the academic programs. On the other hand, there are encountered risks in involving stakeholders if left with no objective guidance, especially that quality agencies are formidably urging the universities to consider the external stakeholders’ inputs to satisfy the quality assurance standards. The main objective of this chapter is to investigate the types of stakeholders’ and their levels of involvement within the local higher education institutions (HEIs). The chapter aims to provide an insight to invest in this involvement and utilize it to further improve the programs and their graduate attributes and suggests actions that would proficiently and truly enhance the involvement of external stakeholders. The outcomes of this chapter are expected to guide the EQAs and the HEIs to develop new practices in involving stakeholders, such as curriculum input, collegiate internships, aligning graduate attributes to market needs, financial support through endowments, professional development, and partnerships in service-level agreements.
