Scalar terms, such as “local” and “global,” “big” and “small” are fundamental in how academics and practitioners make sense of and respond to grand challenges. Yet, scale is so taken-for-granted that we rarely question or critically reflect on the concept and how it is used. The aim of this paper is to identify scale as an important concept in research on grand challenges and to point out why taking scale for granted can be problematic. In particular, I suggest that to date most research on grand challenges sees scale as a fundamental ontological feature of the world. Yet, scalar categories and hierarchies are not as self-evident and given as they may seem. Moreover, taking scale as an ontological fixed category limits our ability to make sense of, theorize and respond to grand challenges. As an alternative, I suggest seeing scale as an epistemological frame that participants employ in their everyday practices to make sense of, navigate and develop solutions to grand challenges. The chapter concludes with a research agenda for studying scale as socially constructed in practice.

This chapter presents and discusses various steps to ensure empirical reliability and theoretical validity in the construction of competence scales in graduate surveys. The development of a scale to assess demands of the teacher profession and related abilities in graduates for a German tracer study project serves as an example. Confirmatory factor analysis (CFA), principal component analysis (PCA) and Cronbach’s coefficient alpha are employed to test the reliability of the scale. Differing results illustrate how the method applied influences decisions in the process of developing a scale. Our findings show that multidimensionality can only be tested appropriately by CFA; PCA renders no feasible or similar results to CFA depending on the predetermination of the number of factors; Cronbach’s alpha produces misleading results as the prerequisite assumption of unidimensionality is violated by the data.

There are many indications that government policymakers and supporters of large-scale nuclear expansion in Poland have not seriously grappled with arguments critical of this direction of the country's power development. Instead, there is a mood of euphoric elation in these circles without even an attempt to reflect on why this kind of nuclear power is in a state of perennial crisis and lack of development prospects in Western countries.

The purpose of this chapter is to consider from an economic perspective the potential role of nuclear power in decarbonising the Polish power sector. It needs to answer two questions: why not develop large-scale nuclear power and why small modular reactors (SMRs) can be a better alternative for decarbonisation of the Polish power sector.

The primary research method used in the preparation of this chapter is a critical analysis and synthesis of the literature on the subject.

A technological revolution will offer electricity customers increasingly better alternatives. Among them there is also technology of SMRs which seems to be much less risky option in terms of its compatibility with the direction of the power sector's evolution as well as cost of sectors’ decarbonisation.

The current era of the fourth industrial revolution has attracted significant research on the use of digital technologies in improving construction project delivery. However, less emphasis has been placed on how these digital tools will influence the management of the construction workforce. To this end, using a review of existing works, this chapter explores the fourth industrial revolution and its associated technologies that can positively impact the management of the construction workforce when implemented. Also, the possible challenges that might truncate the successful deployment of digital technologies for effective workforce management were explored. The chapter submitted that implementing workforce management-specific digital platforms and other digital technologies designed for project delivery can aid effective workforce management within construction organisations. Technologies such as cloud computing, the Internet of Things, big data analytics, robotics and automation, and artificial intelligence, among others, offer significant benefits to the effective workforce management of construction organisations. However, several challenges, such as resistance to change due to fear of job loss, cost of investment in digital tools, organisational structure and culture, must be carefully considered as they might affect the successful use of digital tools and by extension, impact the success of workforce management in the organisations.

This chapter is dedicated to understanding the idea of international as a key notion to the development of globalisation and to promoting the rescaling of spaces and subjects in contemporary higher education. The author discusses the concept of scale as a performative device that activates the capacities of bodies. Instead of seeing scale as a naturalised and hierarchical structure of spatial distribution, the author understands it as an ensemble of discourses and practices that produce scalar effects. Globalisation uses scale to promote the idea that subjects would become ‘international’ by being linked to privileged spaces and bodies in the Global North. In this sense, globalisation is not merely about nodes where certain flows converge. Rather, the author understands it as the political conditions that control and constrain the space for certain flows to occur and not others. Using assemblage analysis, the author presents and analyses three scenes taken from his ethnographic records that have as a guiding line the materialisation of the international. These scenes report the experience of being a Latin American doctoral student attending a congress in the United States, a tense situation experienced at a Chilean university academic event, and the unpretentious manifestation of an elaborate idea of internationality from a personal experience of a trip to India. The results point to three elaborations of the international: an optimistic view of a shared world, a geopolitical internationality and the production of a global corporeality.

In this chapter, the authors take a close look at the current discourse of food system relocalization. From the perspective of theories of justice and theories of neoliberalism, food relocalization is wrapped up in a problematic, and largely unexamined, communitarian discourse on social justice. The example for California's localized governance of pesticide drift demonstrates that localization can effectively make social justice problems invisible. The authors also look at the EU context, where a different form of localization discourse emphasizes the local capture of rents in the value chain as a neoliberal strategy of territorial valorization. Examining Marsden et al.'s case study of one of these localization projects in the UK, the authors argue that this strategy does not necessarily lead to more equitable forms of rural development. In fact, US and EU discourses are basically two sides of the same coin. Specifically, in neoliberal biopolitical form, they both obscure politics, behind either the discourse of “value” in the EU or “values” in the US. Rather than rejecting localism, however, the authors conclude by arguing for a more “reflexive” localism that harnesses the power of this strategy while consciously struggling against inequality in local arenas.

This study presents findings leading to the conclusion that cyberbullying in massively multiplayer online (MMO) games can be conceptualized, measured and at least partially explained as a normative phenomenon, similar to Latane & Darley's (1970) bystander inaction hypothesis. An overall sample of N=372 respondents to an online survey provided information on their daily amount of Internet use and daily amount of time engaged in playing in MMO games. Scales for the assessment of both cyberbullying victimization and bullying itself were developed. Victims of cyberbullying appear more sensitive to bullying incidents albeit no more likely than game players who have engaged in bullying to intervene in preventing it. Perpetrators of cyberbullying, however, also appear to be heavily invested in both Internet use and MMO game play and that could amplify an individual's aggressiveness as a player in turn making it more likely they will engage in cyberbullying. The study concludes with a qualitative examination of MMO game player narrative self-explanations for nonintervention in cyberbullying that parallels Latane and Darley's explanation of bystander nonintervention in face-to-face threatening or emergency contexts.

Two interrelated theoretical schemes on leadership are presented in this paper. One is the Chinese CPM leadership behavior model, and the other, the Chinese implicit leadership theory. The CPM model recognizes three factors: Moral Character (“C” factor), Performance (“P” factor) and Maintenance (“M” factor). The Chinese implicit theory on leadership differentiates four trait factors: Personal Morality, Goal Efficiency, Interpersonal Competence, and Versatility. As such, it corresponds well with the CPM theory’s three-factor model. Both of these studies point to the salience of a cultural aspect. It has been demonstrated in the Chinese cultural context that the Chinese still place key importance on the moral character of their leaders and their behavior.
