Concerns have been raised regarding the mental health of firefighters. In response to this, existing literature reviews have highlighted the significant role of trauma in influencing mental health and the experience of post-traumatic stress within firefighters.

This paper builds on the existing reviews and makes an original contribution to knowledge by systematically reviewing research exploring additional factors that contribute to poor mental health in firefighters.

This review finds that factors such as sleep, occupational stress, length of service, coping style and social support all influence negative mental health within firefighters. However, this paper also suggests there are challenges to distinguishing the nature of these relationships, due to the possible bidirectional nature of the relationships and study limitations.

Finally, we conclude by suggesting a clear need for further research to explore the biological, psychological and social factors influencing mental health outcomes in firefighters and the direction of these relationships, in order to inform effective intervention and support.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

Despite the important role of entrepreneurial implementation intentions for closing the intention-behavior gap, empirical evidence on their drivers and mechanisms is scant and inconclusive. In the case of college students’ technology-driven entrepreneurship, the objective of the present study is to examine whether implementation intentions are contingent on the university environment in which the progression from entrepreneurial intentions to subsequent actions unfolds. The sample for this study is composed of 299 Bulgarian STEM students, who reported technology-based entrepreneurial intentions. A binary logistic regression is applied to examine four specific mechanisms that facilitate or impede the students’ actual implementation intentions. Findings suggest that students enrolled in universities that provide greater concept development support are more likely to have formed specific implementation intentions, while students in more research-intensive universities are less likely to do so. Practitioner implications and recommendations for future research are provided.

This chapter challenges middle-class bias in work-life literature by examining work-life balance dynamics through a social class perspective. It reveals class-based disparities in physical, temporal, and psychological outcomes, including the role of economic capital in work-life balance and the challenges encountered by the socially mobile in achieving psychological balance. It emphasizes the need to acknowledge social class implications for work-life balance and urges organizations to address class-based inconsistencies and inequalities in their practices.

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.

1. Hydrolysis of cassava peels using 13.1 M H₂SO₄ at 100 ^oC for 110 min gave high Glucose productivity

2. Highest ethanol production was obtained at 72 h of fermentation using Saccharomyces cerevisiae

3. Optimal bioethanol concentration and yield were obtained at a hydration level of 35% agitation

4. Highest ethanol productivity and fermentation efficiency were 17.3%, 0.139 g.L⁻¹.h⁻¹
