The second chapter covers the main characteristics of transition time in the four countries: Italy, Greece, Spain, and Portugal. After developing the theoretical model on paths of transition, with a focus on social movement participation, the chapter looks at social movements and protest events as turning points during transition, covering in particular the specific movement actors, their organizational models, and their repertoires of action and frames. The chapter focuses on two dimensions: the role of mobilization in the transition period, which implies the analysis of how elites and masses interact, ally, or fight with each other in the process, and the outcome of transitions as continuity versus rupture of the democratic regime vis-à-vis the old one. It concludes by elaborating some hypotheses on how different modes of transition may produce different types and uses of (transition) memories.

In a study of forty-three preschool children, ratings of four types of the children's imaginativeness were correlated with observational, behavioral, and interview measures. Research questions were: 1) Do correlates of imaginativeness found in observational studies replicate if trait rather than state measures are examined? 2) Do different types of imaginativeness have different correlates? and 3) What characteristics distinguish children at the maladaptive extremes of imaginativeness from those at more moderate levels? The conceptual and empirical utility of considering imaginativeness to have two dimensions, Expressive and Constructive, was demonstrated. While optimal levels of Constructive Imaginativeness correlated significantly with other indices of healthy child development, the correlations were fewer and tended to be weaker for Expressive Imaginativeness. The negative implication of extremes was documented.

Statistical mechanical ensembles of interacting systems localized at the sites of a regular lattice and each having four possible states are considered. A set of lattice functions is introduced which permits a considerable simplification of the partition function for general nearest-neighbor interactions. The particular case of the Potts four-state ferromagnet model is solved exactly in two dimensions. The order–disorder problem for a certain quaternary alloy model is also solved exactly on a square net. The quaternary alloy model has the interesting property that it has two critical temperatures and exhibits two different types of long-range order. The partition function for the spin-3/2 Ising model on a square net is expressed in terms of graphs without odd vertices, but has not been solved exactly.

The classic cell culture involves the use of support in two dimensions, such as a well plate or a Petri dish, that allows the culture of different types of cells. However, this technique does not mimic the natural microenvironment where the cells are exposed to. To solve that, three-dimensional bioprinting techniques were implemented, which involves the use of biopolymers and/or synthetic materials and cells. Because of a lack of information between data sources, the objective of this review paper is, to sum up, all the available information on the topic of bioprinting and to help researchers with the problematics with 3D bioprinters, such as the 3D-Bioplotter™. The 3D-Bioplotter™ has been used in the pre-clinical field since 2000 and could allow the printing of more than one material at the same time, and therefore to increase the complexity of the 3D structure manufactured. It is also very precise with maximum flexibility and a user-friendly and stable software that allows the optimization of the bioprinting process on the technological point of view. Different applications have resulted from the research on this field, mainly focused on regenerative medicine, but the lack of information and/or the possible misunderstandings between papers makes the reproducibility of the tests difficult. Nowadays, the 3D Bioprinting is evolving into another technology called 4D Bioprinting, which promises to be the next step in the bioprinting field and might promote great applications in the future.

E Learning

The goal of this chapter was to study the political strategies utilized in the context of e-learning. The research is based on the e-learning political strategies (ELPoS) model. The model is based on two dimensions: (1) the direction of the political strategy (upward or downward) and (2) the scope of the political strategy (individual or group based). The model assumes that the interaction between these dimensions will define four different types of e-learning political strategies, which, in turn, will lead to different outcomes. The model is presented in the context of the literature on e-learning and is accompanied with four short case studies that demonstrate its political strategies. The discussion and conclusions section integrates the findings from the case studies and outlines the rules that govern the utilization of political e-learning strategies in different organizational contexts.

Although fandom has a rich history within pop culture, it is difficult to know what constitutes a fandom, what differentiates fandoms from similar phenomena as well as what different types of fandoms exist and how fandoms are formed and maintained. In this chapter, the authors define fandom and the related member actions that create and maintain fandoms, as well as delineate the concept from the similar fan-brand communities of transactional brand communities, social brand communities and brand publics. A typology for fan-brand communities is presented with two dimensions: 1) motivation for engagement; and 2) social status and relationship type. This typology can help guide researchers, brands, and marketers in effectively managing different subcultures of fans. This chapter may be used as a starting point for further understanding of fan-brand community-based relationships.

Educational Programmes

PurposeHow university context (UC) enhances students’ entrepreneurial intentions and opportunity recognition is an emerging topic. It is known that students learn, not only from educational programmes, but also from the context in which they are embedded. The purpose of this paper is to investigate the effect of such context on student’s entrepreneurial intentions and opportunity recognition.Design/methodology/approachThe authors use a three-dimensional institutional framework to describe UC including regulative, normative and cognitive structures. Regulative structures refer to rules and regulations, support initiatives in relation to entrepreneurship; normative structures include shared values and norms; while cognitive structures apply to knowledge among students and faculty. A heterogeneous sample of 196 respondents from five countries was used to create reliable measures of UC and to test the hypotheses with the help of regression analysis.FindingsThe findings indicate that two dimensions of UC in particular (regulative and normative) were shown to be of great importance in increasing entrepreneurial intentions and opportunity recognition among students.Originality/valueThe study contributes to this further by suggesting a reliable and theory-grounded scale of UC. Furthermore, this study adds to the discussion on entrepreneurship education by proving evidence of the importance of UC on entrepreneurial intentions. The important contribution is acknowledgement of the fact that social systems both constrain and enable entrepreneurs in their discovery, evaluation and exploitation of opportunities. The authors have established that “would-be student entrepreneurs” do not exist separately from their structural context. Attempts to understand them outside of this context cannot, therefore, fully capture their nature.

The Impact

Bulking and foaming phenomena in activated sludge wastewater treatment plants are in most cases related to the abundance of filamentous microorganisms. Quantifying these microorganisms should be a preliminary stage in their control. In this paper, the simplicity of quantifying them based on the intersection method is demonstrated, by redescribing the theory and applying a new improved protocol; new data of interest are also provided. The improved method allows us to use it with stained smears, including epifluorescence techniques. The error that could be made, when considering the distribution of filamentous bacteria in fresh microscope preparations in two dimensions rather than three is negligible. The effect of the different types of filamentous microorganisms on the settleability was also studied. The effect of the total extended filament length on the sludge settleability was shown to depend on the type of filamentous organism and how it aggregates. When these groups of filamentous organisms are found in small aggregations and there is an increase in the number of filamentous organisms, the sludge volume index (SVI) increases proportionally to the filament length. However, when aggregation increases, the impact on the SVI is significantly lower.

Knowledge Access

Purpose – The purpose of this paper is to address the strategies adopted by science-based start-ups to gain access to knowledge resources at diverse spatial levels. It investigates the presence and relative importance of ties endowed with different types of proximity in firms’ knowledge networks, and the role played by non-geographical proximity in gaining access to knowledge sources, both nearby and distant. Design/methodology/approach – An analytical framework is proposed that distinguishes between two dimensions of proximity – geographical and relational – leading to different forms of proximity, which are further linked with modes of knowledge interaction (formal or informal). A methodology for network reconstruction is developed and applied to Portuguese molecular biology firms, permitting to identify the origin, location and nature of the ties and to position them along forms of proximity. Findings – The results show that the incidence and mix of the different forms of proximity vary in firms’ individual networks, being possible to identify several patterns. They also uncover the relevance of relational proximity, whether or not coexisting with geographical proximity and often compensating for its absence. Research limitations/implications – This approach needs to be complemented with further research that refines the operationalization of relational proximity, by attempting to disentangle the influence of different types of non-geographical proximity. Further research will also explore in greater detail the factors that may explain variety in the proximity mix of firms’ networks. Practical implications – The paper offers insights into the knowledge sourcing strategies adopted by science-based firms located outside the main concentrations of knowledge in their field. Originality/value – The paper contributes to the literature on the role of proximity in knowledge access, by developing and empirically testing a taxonomy of forms of proximity, considering the characteristics of science-based firms. It uncovers the mechanisms through which relational proximity can contribute to span spatial boundaries, highlighting the role played by entrepreneurs’ personal networks.

Digital technology giants dominate the list of the largest publicly traded companies worldwide. This book analyses mergers and acquisitions by these firms from three perspectives—it examines the effect of such activity on the value of the acquirer and on the value of different groups of rivals, and compares it with the effect of other firms’ acquisitions. The author integrates research from finance, information systems, strategy and economics, and investigates the aforementioned value effects on different types of companies. He identifies factors that drive value creation and discusses them in relation to the market environment, digital giants’ special role and potential managerial motives.
