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.

The purpose of this paper is to consider what safeguarding responses to discriminatory abuse and hate crime might learn from existing research on restorative justice and to drive practice development based on available evidence.

This paper is based on a scoping review of literature using four academic databases and reference harvesting. This comprised a critical appraisal of 30 articles, which were thematically analysed to appreciate the benefits and challenges of restorative justice responses to hate crime and how this might inform safeguarding responses to discriminatory abuse and hate crime.

The analysis identifies four domains where learning can be drawn. These relate to theory on restorative justice; restorative justice practices; perspectives from lived experience of restorative justice and hate crime; and an appraisal of critiques about restorative justice.

This paper connects the emerging evidence on restorative criminal justice responses to hate crime to the “turn” towards strengths-based practices in adult safeguarding. Although this provides a fertile environment for embedding restorative practices, the authors argue certain precautions are required based on evidence from existing research on hate crime and restorative justice.

This study aims to outline the research field of initial public offerings (IPOs) pricing and performance by combining bibliometric analysis with a systematic literature review process.

The study uses over three decades of IPO publication records (1989–2020) from Scopus and Web of Science databases. An analysis of keyword co-occurrence and bibliometric coupling was used to gain insights into the evolution of IPO literature.

The study categorized the IPO research field into four primary clusters: IPO pricing and short-run behaviour, IPO performance and influence of intermediaries, venture capital financing and top management and political affiliations and litigation risks. The results offer a framework for delineating research advancements at different stages of IPOs and illustrate the growing interest of researchers in IPOs in recent years. The study identified future research potential in the areas of corporate governance, earning management and investor sentiments related to IPO performance. Similarly, the study highlighted the opportunity to test multiple theoretical frameworks on alternative investment platforms (SME IPO platforms) operating under distinct regulatory environments.

To the best of the authors’ knowledge, this paper represents the first instance of using both bibliometric and systematic review to quantitatively and qualitatively review the articles published in the area of IPO pricing and performance from 1989 to 2020.

Highly committed, motivated and engaged employees assure organizational success and competitiveness. The study aims to examine the association between human resource development (HRD) practices and employee engagement with organizational commitment as a mediating variable.

Data were collected from 760 employees of 13 star-rated hotels comprising 5 (five-star) and 8 (four-star). The data supported the hypothesized relationships. Structural equation modeling was used to evaluate the proposed model and hypotheses. Construct validity and reliability were established through confirmatory factor analysis.

The results indicate that HRD practices and affective commitment are significantly associated. HRD practices and continuance commitment were shown to be non-significantly associated. HRD practices and normative commitment were shown to be non-significantly associated. Employee engagement and organizational commitment are significantly associated. The results further show that organizational commitment mediates the association between HRD practices and employee engagement.

The generalizability of the findings will be constrained due to the research's hotel industry focus and cross sectional data.

The study's findings will serve as valuable pointers for stakeholders and policymakers of the hotel industry in the adoption, design and implementation of proactive HRD interventions to keep highly engaged and committed employees for organizational competitiveness and sustainability.

By evidencing empirically that organizational commitment mediates the nexus between HRD practices and employee engagement, the study extends the literature.

Understanding which market to invest in for a well-diversified portfolio is fundamental in economies that are highly vulnerable to fluctuations in exchange rates. Extant literature that has considered phenomenon hardly juxtapose the markets. The purpose of this study is to examine the effects of exchange rate volatility on the Stock and Real Estate market of South Africa. The essence is to determine whether the fluctuations in the exchange rate influence the markets prices differently.

The Generalised Autoregressive Conditional Heteroskedasticity [GARCH (1.1)] model was used in establishing the effect of exchange rate volatility on both markets. This study used monthly South African data between 2000 and 2020.

The results of this study showed that increased exchange rate volatility increases stock market volatility but decreases real-estate market volatility, both of which revealed weak influences from the exchange rates volatility.

This study has implication for policy in using the exchange rate as a policy tool to attract foreign portfolio investment. The weak volatility transmission from the exchange rate market to the stock and real estate market indicates that there is prospect for foreign investors to diversify their investments in these two markets.

This study investigated which of the assets market, stock or housing market do better in volatile exchange rate conditions in South Africa.

Ethnography produces accounts; the critical reflection of accounts produces accountability. Ethnography requires accountability if meaningful conclusions and/or observations are to be made. Accountability requires ethnography if is to address lived experiences. Virno argues that the principles of “languaging” make ethnographies and accountability possible. This papers aims to describe an instance of the circularity of accountability and use this to explore Virno’s insights. Doing this helps us to see the connections between accountability and ethnography, and reflect on the nature of these interconnections.

Inspired by Paulo Virno’s philosophy, the authors assert that an ethnographer typically produces an account of a chosen “Other” in which this “Other” is held to account. But at the same time, the ethnographer needs to be held to account by the very same “Other” and by the “Other” of the (research) community. Furthermore, ethnographers are accountable to themselves. All these moments of accountability can endlessly circle, as responsibilization of the researchers by their Other(s) continues. For ethnography to function, this must be tamed as a (research) account ultimately has to be produced for an academic project to be considered complete. Drawing on Virno’s principle of the “negation of the negation” by the “katechon,” by the “katechon,” the authors propose a potentially valuable intervention that would enable ethnography – and by extension, ethnographers – to prosper.

The authors apply Virno’s philosophical reflections to propose a positive feedback cycle between ethnography and accountability. Virno’s ideation centers on two key concepts: (i) the multitude of social relatedness and (ii) the ontology of the languaging of individuation. Hereby, a positive circle of causality between ethnography and accountability can be realized, whereby the authors can respect but also break the causal circle(s) of ethnography and accountability. This might be achieved via a reflection on Virno’s concept of the “katechon.”

The authors illuminate the accountability–ethnography dynamic, providing an illustration of the circularity of ethnography and accountability and showing how Virno provides us with tools to help us deal with it. Hence, ultimately, the paper focuses on the accountability as ethnographers.

This study aims to explore relationships among supervisors’ socialization behaviors, newcomers’ socialization outcomes, organizational commitment, and work outcomes in three large companies in Korea.

The research was conducted via an online survey in three large firms in Korea. The sample comprised newcomers who had worked for more than six months but less than one year in these firms. The collected data were analyzed using descriptive statistics and structural equation modeling (SEM).

Derived from SEM, the study’s results confirmed a causal relationship between supervisor’s socialization behaviors and newcomer’s work outcomes, which was fully mediated by newcomer’s socialization outcomes. However, organizational commitment was observed as a mediating variable, not a moderating variable. All types of supervisors’ socialization behaviors were related to newcomers’ socialization outcomes. Providing appropriate feedback, supporting newcomers’ development and improving social relationships were most strongly related to newcomers’ socialization outcomes.

This study proposed a rationale for the potential effectiveness of supervisor socialization behavior training. Related variables such as supervisor training aspects and the effectiveness of supervisor training for newcomers’ organizational socialization could be examined further.

The study offers critical areas to consider when designing training programs focused on supervisors’ socialization behaviors. Human resource development practitioners should be aware of the importance of supervisors’ socialization behaviors for newcomers’ organizational socialization and develop a program to improve all types of supervisors’ socialization behaviors.

New areas of training and development for supervisors can be proposed to improve newcomer organizational socialization and, eventually, to enhance the work outcomes of newcomers.

Cryptocurrencies are becoming increasingly attractive as alternatives to traditional currencies. Although many retailers accept cryptocurrencies as a means of payment in online shopping, consumers’ cryptocurrency adoption intention in online shopping (CCAI) is still low. This study aims to investigate the influence of attitudes, subjective norms, consumer trust, financial literacy and fear of missing out (FOMO) on CCAI.

A quantitative research approach was followed using a consumer survey. Hypothesized relationships were tested through regression and mediation analyses.

The results revealed that consumers could accept cryptocurrencies as a means of payment in online shopping. Attitudes, subjective norms, consumer trust and financial literacy directly and positively influence CCAI, while they indirectly affect CCAI through the mediating impact of FOMO.

Marketing managers should improve consumers’ knowledge about cryptocurrencies and trust in online shopping to increase CCAI. Social media marketing can be appropriate, while the advertising content can address keeping up with others and staying connected.

This study addresses a critical gap in the literature by empirically examining the antecedents of CCAI within an original conceptual model based on the theoretical framework provided by the theory of planned behavior. Attitudes, subjective norms, trust and financial literacy influence CCAI, where FOMO plays a significant role as a mediator.

This study investigated the relationship between last-mile distribution or delivery (LMD) and commodity access through the mediating role of commodity availability and commodity security and the moderating effect of supply chain integration (SCI).

The study adopted the survey research design and employed the questionnaire instrument in collecting primary data from respondents in Eastern Regional Health Institutions in Ghana. The total number of valid responses received was 204. The partial least squares structural equation modeling (PLS-SEM) approach was adopted to analyze the relationship between the study variables.

The findings showed that there is a positive and significant relationship between LMD and commodity availability as well as LMD and commodity security. Moreover, while the relationship between commodity availability and commodity access is positive and significant, that between commodity security and commodity access is positive but insignificant. Furthermore, there is a positive and statistically significant relationship between LMD and commodity access. The study discovered that the interaction between LMD and commodity access is insignificant and negatively affected by SCI.

To the best of the authors' knowledge, no previous studies have empirically verified the effect of LMD on commodity access in the presence of mediating factors such as commodity availability and commodity security and SCI as the moderating factors.

This study investigates how the degree of internationalization (DOI) affects the financial performance of emerging market companies by making the distinction between export intensity and multinationality (i.e. foreign direct investment). The authors argue that the different DOI-performance patterns in the literature relate to different internationalization approaches, which are moderated in distinct ways by formal institutions in the home country.

Based on data of Brazilian firms in several industries and with different internationalization patterns including 100 exporting firms and 30 multinational companies with varying degrees of multinationality over a period of five consecutive years, the authors test their hypotheses using an unbalanced panel data with 346 firm-year observations. In order to test how the quality of formal institutions moderate the DOI-performance relationships, the authors estimate the changes in the slope of the regression line by adding and subtracting one standard deviation to the Worldwide Governance Indicators (WGI) variables.

A positive and linear association between export intensity-performance (EI-P) highlights the location specific comparative advantages of exporting Brazilian firms, while the multinationality-performance (M-P) relationship points to a horizontal S-shape pattern which conforms to the theoretical assumptions of the three-stage internationalization process. Formal institutions moderate positively the EI-P relationship, but moderate negatively each of the three stages of the M-P relationship.

The findings from this study provide critical insights that contribute to the ongoing debate on how formal institutions in the home country affect the DOI-performance relationship of emerging market companies (EMCs). However, the authors consider that it has limitations as they focused exclusively on formal institutions captured by governance institutions in the Brazilian context.

This study provides relevant insights to managers and policy makers. Findings reveal that strong formal institutions in the home country make it easier (cheaper) for EMCs to invest abroad, and, at the same time, increase the efficiency of exporting firms and positively influence financial performance. Moreover, results show that during downturns in their domestic markets, multinational EMCs outperform domestic firms. In that sense, while policy makers can promote the internationalization and competitiveness of EMCs by implementing more supportive formal institutions, managers should consider a proactive approach and invest abroad when conditions in the home country are favorable.

By making the distinction between export intensity and multinationality this study contributes to the literature on the DOI-performance of EMCs providing a more nuanced view on how formal institutions in the home country moderate the EI-P and M-P relationships in different ways.
