The effects of a number of metals and alloys on the thermal stability of Avtur 50 have been evaluated from ASTM‐CRC and high temperature coker tests. The materials tested are used in current aircraft fuel systems or are possible alternatives for fuel systems of supersonic aircraft where they will be in contact with hot fuel. The alloys currently used in aircraft fuel systems have been classified and their probable effects on the stability of hot fuel listed. A number of the materials affected stability adversely, particularly alloys containing significant amounts of copper, and the use of these should be avoided. The pick‐up of copper by Avtur 50 at ambient temperature from alloys such as brass and gun‐metal has also been investigated. The results indicated that sufficient copper to affect thermal stability adversely is readily picked up from these alloys.

This paper explores how two understudied characteristics of a firm's product portfolio, namely, aging of products and (non)innovativeness of products, affect firm survival. The influence of these product portfolio characteristics on organizational mortality can be observed both at the firm and at the industry levels. Paradoxically, the portfolio's influence at the firm and at the industry levels may go in opposite directions. Specifically, I predict that portfolios with aging products make their firms weaker competitors and survivors. However by weakening these firms, “aging” portfolios reduce competitive pressures at the industry level and, therefore, improve firm survival indirectly by changing industry vital rates. In contrast, firms with innovative product portfolios should be stronger survivors. At the same time, they are likely to intensify competition in the industry and, as a result, diminish survival chances of all firms, including those with innovative products. The analyses of all firms’ product portfolios in the worldwide optical disk drive industry, 1983–1999, support these predictions.

In the past many scientists have published papers on hormesis, on molecular stress responses, and on the similia principle in homoeopathy. Very few, however, have stressed a common base of interdependence of these fields. Reviews the most important of these studies to demonstrate their evolution and their mutual importance. Furthermore, a multidisciplinary approach is chosen to demonstrate research into the beneficial effects of subharmful doses of toxicants administered in suboptimal conditions (such as in stressed or injured organisms and cells).

This study investigates the impact of state antitakeover legislation on the market value of affected firms and considers the role that both acquisition attractiveness, as measured by firm size, and antitakeover amendments play in the market reaction. When separating the sample by size and by the presence of amendments, small firms display a negative reaction to the legislation, large firms show no reaction, firms without amendments react negatively, and there is a positive reaction for firms with amendments. When separating the sample on the basis of both dimensions, small firms without amendments, the most attractive acquisition targets, experience a significant, negative market response. Large firms with amendments, the least attractive group, are positively affected. The two intermediate groups are not significantly affected.

The aim of this study is to examine the impact of abusive supervision on employees' emotional and work-related outcomes, using a theoretical framework that integrates affective events theory (AET) and self-determination theory (SDT). The research sought to explore the effects of abusive supervision on subordinates' positive and negative affect, and the subsequent impact on customer orientation and life satisfaction.

The data for this study were collected cross-sectionally through a structured questionnaire completed by employees who have experienced abusive supervision in their current or previous jobs. Structural equation modeling (SEM) was used to analyze the data.

The results indicated that when subordinates experienced abusive supervision, they reported lower levels of positive affect and higher levels of negative affect. These emotions, in turn, impacted their customer orientation and life satisfaction. Positive affect was found to positively influence both customer orientation and life satisfaction, while negative affect had a negative effect on life satisfaction. Surprisingly, customer orientation was positively impacted by negative affect.

Therefore, the findings of this study suggest that positive and negative affects mediate the relationship between abusive supervision and life satisfaction, but not with customer orientation. This study advances prior research by linking the impact of an abusive supervisor to employees' customer behavior and life satisfaction, using positive and negative affects as mediators, and building upon the theories of AET and SDT.

This study aims to provide an empirical investigation into rising capital flight and the role of institutional quality to mitigate its effect on the real sector in sub-Saharan Africa (SSA).

The study uses the system generalized method of moments and uses data spanning from 1989 to 2020 from 26 SSA countries.

The findings show that capital flight has no direct impact on the real sector while institutional quality adversely impacted the agricultural and industrial sectors. The study also found that institutional quality is unable to mitigate the effect of capital flight on the industrial sector.

This study investigates if institutional quality mitigates the impact of capital flight on the real sector proxied by industrial value-added and agriculture value-added.

Previous research on influence strategies has almost exclusively indicated negative relationships between assertive influence and employee work outcomes; the purpose of this study is to argue that an assertive influence strategy can also lead to both positive and negative work outcomes, when subordinates hold different attributions towards the leaders’ motive of using assertive influence (hereafter “the cause”).

The empirical study was based on data collected from 930 employees in China. The authors developed hypotheses to test the mediating effects of three types of perception in the relationship between an assertive influence strategy and five outcomes, and additional analyses on persuasive and relational influence strategies are also conducted.

Results show that when subordinates attribute the cause to their ability (internal attribution), an assertive influence has indirect positive effect on felt obligation, organizational commitment, job performance and organizational citizenship behavior; when subordinates attribute the cause to the poor relationship with their superiors (relational attribution), an assertive influence has indirect negative impact on most outcomes except for job performance; when subordinates perceive that the cause is to the superiors, such as authoritarian leadership (external attribution), an assertive influence has indirect positive effect on job performance.

The study highlights the importance of subordinates’ perceptions during the leadership influence processes.

This study was the first to examine the mediation relationship between three types of influence strategies and five organizational outcomes based on a large sample of front-line staff in China. The findings of the study also enrich the literature of leadership and attribution theories.

The purpose of this paper is to investigate and analyze the challenges of quality skill development in complex and large economies like India and develop innovative processes of improving employability.

The problem areas and gaps have been identified through literature survey and published reports by governmental agencies on employability and quality skill development in India. The research focuses on prevalent challenges for large-scale skill development and utilizes TRIZ (Russian acronym for “Theory of Inventive Problem Solving”) for finding innovative solutions to the grand challenge of employability.

The applied research methodology in the paper leads to a model for the “Innovation driven ecosystem for quality skill development” and also defines the role and responsibilities of each stakeholders in the ecosystem.

Solutions derived through TRIZ are qualitative in nature. The actual implication of solution needs to be tested after implementation. Further, intangible costs incurred, and harmful and useful effects cannot be easily quantified.

The parameter mapping for the TRIZ matrix was undertaken in this paper and this methodology when applied to other problem statements renders an organized process for improving total quality and innovative process management. The inventive principles were applied to find solution to contradictions and arrive at an integrated ecosystem which binds all stakeholders efficiently, to generate higher employability. The innovative solutions derived through the process are applicable to policy makers, researchers and practitioners.

The process of improving employability through quality skill development, benchmarked by the TRIZ methodology can have far reaching social implications.

The research extends the body of knowledge of TRIZ modeling concepts in areas other than engineering, and depicts a unique total quality methodology which can be easily applied for other problem-solving contexts. The contribution can serve as a reference technique/tool for improving reliability and quality through a methodical process of working out innovative solutions to solve operational problems.

Travel ban, restriction and health hazards are the results of disruptive shocks in the tourism industry leading to a significant negative impact on the tourism business. We investigated the COVID-19 induced different restrictions effects in Bangladesh through the synthesis of the literature evidence. Our study found the tourism industry is one of the hardest-hit service industries worldwide during the pandemic. The main purpose of this chapter is to discuss the impact of COVID-19 on the tourism and hospitality industry in Bangladesh. New post-epidemic potentials for sustainable tourism growth are outlined. The consequences of COVID-19 in global sustainable tourism are discussed using a qualitative technique based on emergent literature, the most recent tourism reports and content analysis in this chapter. This book chapter complements the literature inventory on COVID-19 by estimating and tracking the world economy's major effects, the impact on sustainable travel and tourism, the effects on nature wildlife tourism and (new) openings for further sustainable tourism. Finally, it analyses the nature and scope of COVID-19's effects on tourism, recovery and resolution in the post-pandemic tourism industry, as well as the suggestions for future growth of sustainable tourism.

This paper describes findings from recent research in the UK on one particular type of bullying, that linked to sexuality and the assumed sexual orientation of the victim ‐ namely homophobic bullying. A survey involving 307 secondary schools throughout England and Wales showed that awareness of general bullying among school staff was almost universal. Most respondents also knew of homophobic verbal bullying, and over one in four were aware of homophobic physical bullying. Existing school policies on bullying and confidentiality rarely referred to lesbian and gay issues. Respondents identified barriers to tackling homophobic bullying, but most thought schools were appropriately placed to provide information on lesbian and gay issues. Study recommendations include: modernising national policy, supporting local teachers and policy‐making in schools through training, new initiatives in citizenship education, and encouraging schools to build collaborative relationships with other local community agencies.
