Ventricular surface activation time maps are estimated from simulated and measured body surface potential (BSP) maps and extra‐corporal magnetic field maps. In a first step the transfer matrix, relating the primary cardiac sources to the measured potential and/or magnetic field data, is calculated applying the boundary element method. Activation times are determined by minimizing a cost function which is based on this transfer matrix. This optimization method is solved by a quasi Newton method. The critical point theorem is used in order to estimate the starting column matrix.

Wirft man einen Blick auf die vergangenen vierzig Jahre der wirtschaftlichen Entwicklung der meisten Volkswirtschaften, insbesondere aber der industrialisierten Staaten, so fällt einem auf, dass in der Zwischenkriegszeit die Kurve der industriellen Produktion sowohl nach oben wie nach unten recht grosse Ausschläge zeigt und nur sehr zögernd nach oben strebt. In der Nachkriegszeit hingegen weisen sämtliche Industrieländer im Produktionssektor einen sehr ausgeprägten, steilen Trend nach oben auf, wobei nur verhältnismässig schwache Ausschläge kon‐junktureller Art feststellbar sind. Von diesem eklatanten Wachstumstrend wurde auch die Schweiz mitgerissen, was sich in einer Verdoppe‐lung des schweizerischen Sozialproduktes (gesamt‐wirtschaftliche Produktionsleistung eines Lan‐des) äusserte und das reale Volkseinkommen pro Kopf der Bevölkerung um 60% ansteigen liess. Diese Phase des wirtschaftlichen Wiederauf‐stiegs musste sich zwangsläufig auch auf den Fremdenverkehr auswirken; mit Genugtuung darf man feststellen, dass sich beispielsweise die Zahl der Ankünfte gesamtschweizerisch seit dem Jahre 1950 verdoppelte und die Übernachtungen im Zeitraum 1950/1965 von 18,6 auf 31,3 Millionen zugenommen haben. Schon mit dieser ersten Gegenüberstellung lässt sich der enge Zusammenhang zwischen wirtschaftlichem Wachstum einerseits und Fremdenverkehr beziehungsweise Übernachtungen in der Hotellerie andererseits nachweisen.

Participative leadership's influence on employee task performance has garnered significant attention in a rapidly evolving organizational landscape. This study explores the multilevel dynamics of participative leadership congruence between unit managers and direct supervisors and its effects on employee task performance.

Drawing on two longitudinal studies based on the firms randomly selected from the Taiwan Economic Journal (TEJ) database, the research observes the mediating role of Person-Unit fit and the moderating influence of Unit-Member Exchange in the participative leadership-performance relationship.

The findings reveal how participative leadership congruence enhances person-unit fit, which in turn benefits employee task performance. Unit-member exchange plays a critical role in augmenting the participative leadership congruence? Person-unit fit? Employee task performance relationship.

The study extends leadership literature by highlighting the significance of leadership alignment across levels and the interplay between psychological and social factors in improving employee performance.

In this paper, the dominant techno-rational view of studying delays in projects is challenged. In so doing, the purpose of this paper is to urge for more attention paid to studying the intentionalities of the planners involved in planning the schedule for projects.

In this paper, the authors take a critical approach to review a range of literatures related to the concept of project delays. Through this review, the authors render the relative absence of acknowledging intentionality in the study of delays problematic. Therefore, the authors inject fresh insights into how intentionality can play a crucial role in advancing the understanding of project delays.

Prevailing research tends to assume the primacy of the project plan and conceptualise delays as a consequence of flawed execution. The review offers three possibilities for reconceptualising delays as a consequence of flawed plans. In so doing, the authors refocus the attention on how intentionality could play a crucial role in shaping “inaccurate” plans, which in turn could lead to the creation of delays.

As a consequence of this review paper, the authors invite scholarship into project delays to move away from finding “cause-and-effect” mechanisms to attend more closely to the role intentionality plays in creating delays, whether intended, unintended, or imagined.

This paper brings intentionality to the fore to challenge the assumptions over the nature of delays. In so doing, the review expands the understanding of project delays by incorporating unintended, intended, and imaginary perspectives.

This paper explores the Entrepreneurial Well-Being (EWB) of expatriate entrepreneurs in China. Through the analysis of their contextualised lived experience across the entrepreneurial journey, the paper proposes a novel theorisation of EWB.

This study adopts an interpretivist approach of abductive reasoning to analyse the data from 50 in-depth interviews conducted with expatriate entrepreneurs in China. Expatriate entrepreneurs are confronted with enhanced challenges in their host country, leading to particular emotional engagement with the entrepreneurial journey.

Findings show the importance of life situations, emotions and relatedness in the entrepreneurial process and the EWB of expatriate entrepreneurs. Theorising from their lived experiences, the paper presents EWB as a dynamic process. It further theorises this process as a constant, ongoing interaction and integration between the self and world, in an interplay of being and becoming. Such theorisation contributes first to advancements in the EWB literature, with a stronger emphasis on the entrepreneurial aspect. The paper also contributes to discussions on contextualised entrepreneurship by stressing the role of emotions and relatedness in the pursuit of EWB.

Entrepreneurship is a global phenomenon, which is often presented as a suitable alternative career path for migrant and expatriate individuals. However, the importance of EWB for entrepreneurs requires further attention from policy-makers, support institutions and entrepreneurs themselves. By theorising EWB as a processual journey of being and becoming and the relation between the self and world, this paper opens avenues for innovative support policies and practices aiming at developing the full potential of individuals in entrepreneurship and promoting both the happiness index and the global index of society.

International entrepreneurship (IE) has received a considerable amount of attention in the recent decades as a result of globalization enabling access to new international markets and business opportunities. Despite the growing increase in academic publications, IE still faces certain inconsistencies, with doubts remaining as regards its boundaries and the thematic groups making up the field. The purpose of this article is to systematically analyse the IE, mapping the intellectual territory and the evolution of the field.

Indexed to Web of Science( WoS) database until 2021, from 52 journals, 130 articles were selected, applying content analyses techniques to identify the main research lines.

The results reveal that IE presents four conceptual themes/clusters: (1) international business networks and opportunities; (2) institutional environments; (3) the characteristics and motivations of entrepreneurs; and (4) internationalisation drivers and processes. Extant analysis show that IE has progressed immensely, concentrating a good diversity of subtopics and research trends. An integrative framework bringing together 27 years of publications and 67 future research lines, detailed by cluster, were also presented in this study to improve understanding and guide future studies.

This review makes a broad contribution to the IE literature, assisting in consolidating the academic field, expanding and complementing the results of previous theoretical–conceptual studies. We reflect and individually discuss the state of the art of the four streams that characterize IE to identify key themes, points of convergence and advance new subfields.

The entrepreneurial education has obtained special attention by researchers hoping to develop better entrepreneurship programmes that may result in higher entrepreneurial activity outputs of students. The culture on its own is one of the main determinants, among others, of the entrepreneurial activities undertaken in different countries. In that sense, this research contributes to a greater understanding of the relationship between culture and entrepreneurial education. Using one of the Global Entrepreneurship Monitor’s surveys, the National Experts’ Survey, the authors used Structural Equation Models to analyse the sample of N =  445 experts in Mexico as an effort to achieve a consensus about which of these two constructs is dependent on the other, ‘entrepreneurial education’ or ‘cultural and social norms’. The results of this chapter show that in Mexico there is an influence of the cultural and social norms on entrepreneurial education at all levels, primary, secondary, and superior. Nevertheless, an important limitation of the study was that it does not differentiate between private and public education, but yet it contributes to the understanding of the less visible entrepreneurial educational levels in the literature. This chapter aims with the phenomena of how teaching entrepreneurship works by analysing the Global Entrepreneurship Monitor’s social environment variable effect on entrepreneurial education. This research contributes to the evidence that the teaching practice under the socio-cultural dimension enables to detect the continuity factors to make an educational transformation.
