Abstract

Purpose

The objective of this article is to investigate the binding of several lactones to soya protein isolate and soya protein under different conditions and, particularly, the extent of binding of the lactones γ‐9, γ‐10, δ‐10 and δ‐11, in different concentrations as well as the effect of various parameters on their binding ability.

Design/methodology/approach

Capillary column gas chromatography was used for the determination of lactones and the manual system was used for taking samples and for headspace analysis. Infrared spectroscopy was used for confirmation and investigation.

Findings

The percentage of binding of lactones γ‐9, γ‐10, δ‐10, δ‐11 on the soya protein is almost the same (about 33‐34 per cent). According to the Klotz equation, the bound ligand concentration was calculating as the number of moles of ligand bound per mole of protein. The results varied, but were similar. Specific experiments in water system with soya protein isolate (1 per cent) showed that the time taken for lactones γ‐10 and δ‐11 to reach equilibrium, the factors of temperature and pH affected the percentage of lactone bound.

Research limitations/implications

The amount of added lactone in products containing soya protein isolate should be investigated by using panel tests to confirm the improvement of flavour.

Practical implications

Flavour binding of lactones can be used to provide some foods with the required flavour impression by adding lactones to a bland soy protein base.

Originality/value

The flavour binding of lactones, which was investigated in the present paper, has not been adequately investigated in previous scientific research and the effects of the factors that influence their binding are very important.

Abstract

Persistent change has placed considerable pressure on organizations to keep up or fade into obscurity. Firms that remain viable, or even thrive, are staffed with decision-makers who capably steer organizations toward opportunities and away from threats. Accordingly, leadership development has never been more critical. In this chapter, the authors propose that leader development is an inherently dyadic process initiated to communicate formal and informal expectations. The authors focus on the informal component, in the form of organizational politics, as an element of leadership that is critical to employee and company success. The authors advocate that superiors represent the most salient information source for leader development, especially as it relates to political dynamics embedded in work systems. The authors discuss research associated with our conceptualization of dyadic political leader development (DPLD). Specifically, the authors develop DPLD by exploring its conceptual underpinnings as they relate to sensemaking, identity, and social learning theories. Once established, the authors provide a refined discussion of the construct, illustrating its scholarly mechanisms that better explain leader development processes and outcomes. The authors then expand research in the areas of political skill, political will, political knowledge, and political phronesis by embedding our conceptualization of DPLD into a political leadership model. The authors conclude by discussing methodological issues and avenues of future research stemming from the development of DPLD.

Abstract

The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.

The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.

In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.

The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.

Abstract

Over the past decade, criminology in Australia, Canada and other settler colonies has increasingly engaged with activist challenges to the penal system. These anti-carceral engagements have been levelled at its laws, institutions and agents. Following a long history of criminology explicating and buttressing penal institutions, the criminological gaze slowly transitioned in the 1970s to a more critical lens, shifting focus from the people who are criminalised to the harms of the apparatus that criminalises. However, the focus remained steadfastly on institutions and dominant players – until much more recently. The COVID-19 pandemic has revealed the strength of activist organisations and grassroots movements in affecting change and shaping debates in relation to the penal system. This chapter will explore the role of activism in informing criminological scholarship during the pandemic period and how criminologists, in turn, have increasingly recognised the need to build alliances and collaborations with grassroots activists and engage in their own activism. The chapter focuses primarily on Australian and Canadian criminology and its growing imbrication with the prison abolition movement, especially in the shadow of ongoing colonial violence. It considers how activist scholars, including ourselves, attempt to build movements for structural change in the criminal system and beyond.

Abstract

The author argues that we must stop and take a look at what our insistence on human labour as the basis of our society is doing to us, and begin to search for possible alternatives. We need the vision and the courage to aim for the highest level of technology attainable for the widest possible use in both industry and services. We need financial arrangements that will encourage people to invent themselves out of work. Our goal, the article argues, must be the reduction of human labour to the greatest extent possible, to free people for more enjoyable, creative, human activities.

Abstract

Organizational researchers studying well-being – as well as organizations themselves – often place much of the burden on employees to manage and preserve their own well-being. Missing from this discussion is how – from a human resources management (HRM) perspective – organizations and managers can directly and positively shape the well-being of their employees. The authors use this review to paint a picture of what organizations could be like if they valued people holistically and embraced the full experience of employees’ lives to promote well-being at work. In so doing, the authors tackle five challenges that managers may have to help their employees navigate, but to date have received more limited empirical and theoretical attention from an HRM perspective: (1) recovery at work; (2) women’s health; (3) concealable stigmas; (4) caregiving; and (5) coping with socio-environmental jolts. In each section, the authors highlight how past research has treated managerial or organizational support on these topics, and pave the way for where research needs to advance from an HRM perspective. The authors conclude with ideas for tackling these issues methodologically and analytically, highlighting ways to recruit and support more vulnerable samples that are encapsulated within these topics, as well as analytic approaches to study employee experiences more holistically. In sum, this review represents a call for organizations to now – more than ever – build thriving organizations.
