Abstract
In this paper, the author seeks to present in easy‐to‐understand diagrams the effect of external loads on the pretensioned bolt in a bolted joint. In most cases, bolted joints are tightened up with little thought for the size of the external loads that may later be imposed upon them. Since external loads always change the preload in the bolt, it is important to know by how much the bolt load changes. Too much preload leaves too little margin for the external or working load; too little preload and the cyclic stresses cause the bolt to fatigue, assuming the bolted joint is subjected to frequent working loads. No two bolts are alike, even under the most rigorous quality control production methods, but with more sophisticated nut and bolt tightening equipment coming onto the market, better results can be achieved. The use of these diagrams will help engineers and designers understand what is happening in the bolted joint.
Fatigue is a problem which all designers have to face. If they are starting on the design of an aeroplane, they will work out all the high loading cases first, make sure that the…
Abstract
Fatigue is a problem which all designers have to face. If they are starting on the design of an aeroplane, they will work out all the high loading cases first, make sure that the design will be good enough to meet them, then they will turn their thoughts to the survival of the proposed structure within the lower stress levels of every‐day operations.

Abstract
Far too often refugees are being researched on; however, the purpose of this chapter is to research with refugees while exploring the ways refugee youth in a higher education protracted context can become producers of research and knowledge. I sought to collaborate with my co-researchers / co-authors through a community-based action (CBA) approach at Kakuma Refugee Camp to assure that their youthful (ages 18–35) voices were included in this study. A CBA approach seeks to speak with participants, not for them. They learned about the research process, why research is needed, and how we can produce it together. Using a critical-hope framework, that is, a pedagogical tool that uses a critical theory lens to address unjust systems through meaningful dialogue and empathic responses, we co-led 30 psychosocial peace-building education (PBBE) courses in Kakuma and Nairobi, Kenya. Data were collected from the researcher and co-researchers’ reflective logs on our own observations in the PBBE courses. A thematic analysis approach was chosen in order to avoid focusing on the norms and/or creating specific norms that dictate, demand conformity, and silence divergent voices. There were three themes: time, place, and person.

The study aims to investigate the potential of green immature soybean among Nigeria soybean varieties as human food.
Abstract
Purpose
The study aims to investigate the potential of green immature soybean among Nigeria soybean varieties as human food.
Design/methodology/approach
Five Nigeria soybean varieties were harvested at 90 days old. The fresh green immature soybean seed were evaluated for chemical composition, physical and sensory characteristics. The physical characteristics looked into seed size (breadth and length), weight, seed colour, hull thickness and percentage of hydration. The chemical composition was compared to mature soybean seeds while the sensory attributes were compared to fresh green peas.
Findings
The raw mature soybean (RMS) was significantly higher and lower in chemical composition and anti‐nutritional factors respectively. The highest moisture content ranges from 62.8 per cent in TGX 1019‐2EB to 65.4 per cent in TGX 1485‐1D. The protein content (15.3 per cent) was highest in TGX1485‐1D and lowest value in TGX1448‐2E. The level of tannin was significantly higher in TGX1448‐2E and 923‐2E while trypsin inhibitor was significantly (p<0.05) higher in TGX1440‐1E and TGX1485‐1D. TGX1485‐1D had superior physical characteristics to other immature varieties with significant (p<0.05) higher value for breadth, length and height. The hull thickness of the seeds was within 0.01 to 0.05 and the percentage of hydration ranges within 5.5 to 6.8 per cent. All varieties had a green colour for the seed coat. Overall sensory acceptability of TGX TGX1440‐1E, 1485‐1D and 1019‐2EB compared favourably well with green peas used as control for sensory evaluation.
Originality/value
This study could help to identify the potential of some Nigerian soybean cultivars for production for use as a source of vegetable in the diet and also provided valuable information for further improvement of soybean for food uses.

The purpose of the study is to examine the role of legitimacy in forming whistleblowing behavior in Ugandan procuring and disposing entities (PDEs).
Abstract
Purpose
The purpose of the study is to examine the role of legitimacy in forming whistleblowing behavior in Ugandan procuring and disposing entities (PDEs).
Design/methodology/approach
This study has adopted both a quantitative and qualitative cross-sectional research design to collect data from a sample of 97 out of the population of 129 PDEs in Kampala, which are regulated by the Public Procurement and Disposal of Assets Authority.
Findings
This paper finds that improvement in the perception of public servants about the appropriateness of the Whistleblowers Act and its enforcers can increase on the reporting of unethical practices in public procurement.
Research limitations/implications
This study has used a cross-sectional survey data. The causal relationships between variables are possibly obscured; as data from all participants are collected at the same point of time, perceptions go on changing over time. Therefore, further studies should use a longitudinal approach. Second, there are no constructs for legitimacy in public procurement and those from law are domesticated.
Practical implications
There should be a promotion of legitimacy of the Whistleblowers Act and the enforcement agencies of the Act. The government should devise means for the public servants to have an obligation to obey the holders of authority, to trust and have confidence in them and to enforce the Whistleblowers Act in an ethical and normative framework.
Originality/value
This study reveals the whistleblowing intentions and behavior of public servants in PDEs. This study would help the Government of Uganda to make the Whistleblowing Act legitimate and its enforcers to increase on the reporting of unethical practices in public procurement.

Abstract
Purpose
The purpose of this paper is to explore the relationship between the determinants of public employee turnover intent and the use of workplace flexibilities, with particular attention on the role that gender plays on the relationship between these two constructs.
Design/methodology/approach
Using a cross-sectional quantitative research design, the data collection specifically targeted employees of US municipalities that had a significant portion of their workforce using some type of alternative work schedule. Nine cities from six different states were included in the data collection.
Findings
In support of prior research and conventional wisdom, the authors find that the use of alternative work schedules is associated with lower expressions of turnover intent, but this relationship is only significant for female municipal employees.
Research limitations/implications
One limitation of the study is that it is mono-source data. A second limitation relates to the lack of controls for contextual and occupational characteristics. Further research is needed on the relationship between alternative work schedule choice and turnover, particularly exploring how other characteristics might impact the relationship between employment flexibilities and turnover.
Practical implications
Overall, the results of the analysis align with broader observations of the need for increasing workplace flexibilities and scholarship exploring these flexibilities, especially for female employees who are attempting to integrate their work and family responsibilities.
Originality/value
There has been relatively little research exploring the relationship between the determinants of turnover intent and the use of workplace flexibilities at the municipal level of government. This is particularly important given that employment in local government is larger than both federal and state government employment combined in the USA (US Census Bureau, 2017).

Abstract
Purpose
In this article focused upon the UK context, the authors sought to better understand how political elites shaped public debate to reinforce rather than challenge the hostile policy environment for those seeking asylum.
Design/methodology/approach
The authors undertook a political claims analysis (Koopmans and Statham, 1999) focussing on a venue that has been pivotal in shaping the discourse around asylum issues in the UK, namely the print media. This work adopts a theoretical frame informed by the work of Stuart Hall to uncover the extent to which debates on asylum during the key period of the refugee emergency in Europe were shaped by political elites.
Findings
The study’s findings reveal the extent to which political elites acted as “primary definers” of the “crisis” and utilised that position to cast those arriving in Europe as a threat to be managed.
Originality/value
This research offers a contemporary worked example of political claims analysis in a topical subject area that colleagues across disciplines and contexts may find informative for their own research agendas.

Abstract
Controversy has long swirled over the claim that Donald Trump's base has deeply rooted authoritarian tendencies, but Trump himself seems to have few doubts. Asked whether his stated wish to be dictator “on day one” of second term in office would repel voters, Trump said “I think a lot of people like it.” It is one of his invariable talking points that 74 million voters supported him in 2020, and he remains the unrivaled leader of the Republican Party, even as his rhetoric escalates to levels that cautious observers now routinely call fascistic.
Is Trump right that many people “like” his talk of dictatorship? If so, what does that mean empirically? Part of the answer to these questions was apparent early, in the results of the 2016 American National Election Study (ANES), which included survey questions that we had proposed which we drew from the aptly-named “Right-Wing Authoritarianism” scale. Posed to voters in 2012–2013 and again in 2016, those questions elicited striking responses.
In this chapter, we revisit those responses. We begin by exploring Trump's escalating anti-democratic rhetoric in the light of themes drawn from Max Weber and Theodor W. Adorno. We follow this with the text of the 2017 conference paper in which we first reported that 75% of Trump's voters supported him enthusiastically, mainly because they shared his prejudices, not because they were hurting economically. They hoped to “get rid” of troublemakers and “crush evil.” That wish, as we show in our conclusion, remains central to Trump's appeal.
