Given the recent explosion of interest in streaming data and online algorithms, clustering of time series subsequences has received much attention. In this work we make a surprising claim. Clustering of time series subsequences is completely meaningless. More concretely, clusters extracted from these time series are forced to obey a certain constraint that is pathologically unlikely to be satisfied by any dataset, and because of this, the clusters extracted by any clustering algorithm are essentially random. While this constraint can be intuitively demonstrated with a simple illustration and is simple to prove, it has never appeared in the literature. We can justify calling our claim surprising, since it invalidates the contribution of dozens of previously published papers. We will justify our claim with a theorem, illustrative examples, and a comprehensive set of experiments on reimplementations of previous work.

This chapter begins with a reflection on the call for investigating how entrepreneurial competencies are developed (Bird, 1995) in the context of university-based entrepreneurship centers. Through clarifying the nature of entrepreneurial competencies and applying a social constructivist perspective of learning, it is proposed that effective nurturing of entrepreneurial competencies for university students through entrepreneurship centers shall be based on five key characteristics; namely, active experimentation, authenticity, social interaction, sense of ownership, and scaffolding support. The chapter contributes to the literature through establishing a link between entrepreneurship education and entrepreneurial competencies in the context of university-based entrepreneurship centers, which have become an increasingly popular way for promoting entrepreneurial development. The practical implications on nurturing entrepreneurs through entrepreneurship centers are discussed, together with the directions for further research. This chapter is designed as a refection upon Bird’s original article articulating the concept of entrepreneurial competencies. In this chapter, the author outlines how entrepreneurial competencies can be developed through education programs, specifically via entrepreneurship centers.

This chapter presents a contextual model of human resources management (HRM). The hallmarks of this model are that (1) the most advantageous HRM practices vary conditionally upon strategic considerations; (2) each organization has multiple substrategies within it, and each substrategy is aligned with a unique bundle of HRM practices; (3) within each organization, three substrategies are associated with three subsystems; and (4) in terms of contributing to sustainable competitive advantage, the innovation subsystem is the most valuable regardless of the organization in question.

This chapter explores what video games can teach us in light of the ongoing sixth mass extinction in the history of our planet, allegedly caused by global warming and the over-consumption of vital resources. Games made and played by nonhuman actors can shed light on the situatedness and partiality of our knowledge regarding the boundaries that separate and differentiate human and nonhuman, interactivity and passivity, entertainment and boredom, and life and death. Nonhuman games help us to articulate the space and time in-between these dualisms and have the potential to re-route gaming (and game studies) from false myths of agency, interactivity, and instrumentalism, and the masculinism inherent in these notions. Nonhuman games are companions for earthly survival, and as such they can be taken as useful references when considering a more ethical approach to the ecological crisis of the Anthropocene. The chapter investigates notions of posthumanism, interpassivity, and contemporary critiques of the early assumptions of game studies on the agency of human players. It looks at video games that play by themselves, idle and incremental games, and the emergence of nonplaying characters in ludic and open-world simulations. It explores forms of automatic play and the use of bots and Artificial Intelligence (AI) in online role-playing games, procedurally generated virtual environments, and games that far exceed the lifespan of their players.

This survey presents the recent and rapidly expanding literature, which analyses the economic impacts of the COVID-19 pandemic, by means of Computable General Equilibrium (CGE) modelling. It does so not only by contrasting and assessing the different methodological approaches, and the key findings of the simulation exercises, but also by putting the various contributions in a historical perspective. This is necessary because each CGE-based study should be evaluated while keeping in mind when it was realised, since questions, priorities, expectations have been constantly changing during the spreading of the pandemic.

The ability to effectively engage in cross-cultural interactions is imperative for leaders in our increasingly globalized world. Those who possess certain key psychological resources are more likely to engage in cross-cultural interactions successfully. Psychological resources include cross-cultural hope, efficacy, resilience, and optimism, which together comprise cross-cultural psychological capital (CC PsyCap). Previous research has indicated that CC PsyCap predicts cultural competence, yet the pathways underlying this relationship remain unexplored. We examined the relationships among CC PsyCap, engagement in cross-cultural interactions, stress during cross-cultural interactions, and cultural competence. The hypothesized relationships were tested using a sample of 135 undergraduate students (76% female) participating in study abroad programs. Participants completed measures of cultural competence, CC PsyCap, engagement, and stress approximately one month into their study abroad. Structural equation modeling analyses indicate that CC PsyCap and stress influence cultural competence directly and indirectly through engagement level during cross-cultural interactions. Furthermore, the results suggest that CC PsyCap indirectly influences engagement through stress during cross-cultural interactions. We discuss the implications of these results for people preparing to enter cross-cultural environments.

Students with learning disabilities (LD) have a wide range of academic needs. Since the passing of P.L. 94-142, significant research has been done on effective interventions for this group of students. Starting with the Learning Disabilities Research Institutes through the recent Handbook of Learning Disabilities, reviews of lines of research make several broad ideas about interventions clear. Primary among these is that students with LD can learn if provided with appropriate, effective instruction. Specifics about this idea and its implications are discussed in the following chapter.

Based on a news media review, this chapter explores how micro enterprises (MEs) and small and medium-sized enterprises (SMEs) within the Norwegian tourism sectors were impacted by COVID-19 in early 2020. It examines central stakeholders' and tourism SMEs and MEs first responses to the pandemic. Similar to previous crises and disasters, the case of COVID-19 demonstrates the reliance on top-down management approaches, notably governmental compensation schemes and subsidies. Given the magnitude of the impacts related to travel bans and border closures, response mechanisms remained largely insufficient. The media reviews reveals that in the first months after the COVID-19 pandemic outbreak, Norwegian tourism SMEs and MEs have responded in five ways that are to some extent time-displaced yet continue simultaneous: (1) early response to business survival, (2) smaller operational changes, (3) employee layoff and bankruptcies, (4) innovation and alternative income sources and (5) gradual reopening. The Norwegian tourism recovery will strongly rely on domestic tourism which requires a reorientation of communication strategies and Norwegianization (Fornorsking) of product development and innovation. Some Norwegian destinations have already demonstrated that high dependability on international tourists and often disintegrated tourism development may threaten sustainability and prosperity of local communities, and post-COVID-19 recovery strategies will be needed that mitigate the dependence on international markets, mono-seasons or tourism as a mono-industry.
