Looks at how layered fabrication processes typically entail extensive computations and large memory requirements in the reduction of three‐dimensional part descriptions to area‐filling paths that cover the interior of each of a sequence of planar slices. Notes that the polyhedral “STL” representation exacerbates this problem by necessitating large input data volumes to describe curved surface models at acceptable levels of accuracy. Develops a geometrical modelling system that captures and processes analytic slice representations, based on models bounded by the natural quadric surface. Finds that empirical results from this system on representative parts systematically yield improvements of between one and two orders of magnitude in efficiency, accuracy and data volume over an equivalent processing of the STL model. Furthermore, discovers that the analytic form is significantly more reliable, since it is not subject to the geometrical or topological defects frequently encountered in STL files generated by commercial CAD systems.

Policy makers have called for more entrepreneurship throughout societies as a response to the digital transformation. This paper argues that the rapidly changing conditions of the digital age indeed mark a change in the bases of entrepreneurship. Specifically, as adaptivity becomes key, a learning capacity and general ability to adapt becomes a critical factor in entrepreneurial activity. The paper identifies self-directed learning (SDL) as a fundamental competence in this regard and examines its role for entrepreneurship and entrepreneurial competence.

The paper develops a theoretical framework for the role of SDL in entrepreneurship through a process of systematic review of previous studies that have linked SDL to entrepreneurship.

The formulated theoretical framework shows how SDL competence combines with experiential learning in supporting the kind of adaptivity needed for entrepreneurial competence, especially under more rapidly changing conditions. SDL competence also gains wider importance through enabling individuals to meet the demands of organizational changes in our highly volatile world.

SDL competence prepares individuals for entrepreneurship and resilience in face of rapid changes as well as for being more entrepreneurial in the conduct of their lives more generally. Fostering SDL competence can thus be regarded as an important objective of entrepreneurship education.

The described self-directed experiential learning cycle offers a novel perspective that clarifies how both self-directed and experiential learning competences are integral for understanding the basis of adaptiveness in entrepreneurial activity.

To determine where, when, how, and wherefore European social theory hit upon the formula of “the True, the Good, and the Beautiful,” and how its structural position as a skeleton for the theory of action has changed.

Genealogy, library research, and unusually good fortune were used to trace back the origin of what was to become a ubiquitous phrase, and to reconstruct the debates that made deploying the term seem important to writers.

The triad, although sometimes used accidentally in the renaissance, assumed a key structural place with a rise of Neo-Platonism in the eighteenth century associated with a new interest in providing a serious analysis of taste. It was a focus on taste that allowed the Beautiful to assume a position that was structurally homologous to those of the True and the Good, long understood as potential parallels. Although the first efforts were ones that attempted to emphasize the unification of the human spirit, the triad, once formulated, was attractive to faculties theorists more interested in decomposing the soul. They seized upon the triad as corresponding to an emerging sense of a tripartition of the soul. Finally, the members of the triad became re-understood as values, now as orthogonal dimensions.

This seems to be the first time the story of the development of the triad – one of the most ubiquitous architectonics in social thought – has been told.

We analyse the dynamics of social assistance benefit (SA) receipt among working-age adults in Britain between 1991 and 2005. The decline in the annual SA receipt rate was driven by a decline in the SA entry rate rather than by the SA exit rate (which also declined). We examine the determinants of these trends using a multivariate dynamic random effects probit model of SA receipt probabilities applied to British Household Panel Survey data. We show how the model may be used to derive year-by-year predictions of aggregate SA entry, exit and receipt rates. The analysis highlights the importance of the decline in the unemployment rate over the period and other changes in the socio-economic environment including two reforms to the income maintenance system in the 1990s and also illustrates the effects of self-selection (‘creaming’) on observed and unobserved characteristics.

Purpose – Harnessing the advantage of mobile information technology (IT) solutions at the point of care and contributing to patients' safety by involving them.

Design/methodology/approach – International collaboration between specialists in health communication processes and information management and systems.

Methods used – Case studies, design science.

Findings – User-friendly portable IT applications going beyond documentation of patient records and administration require an understanding of complex communication processes between patients and the different caregivers. Home care increasingly faces structural deficits to be mitigated by integration of IT solutions. Platforms chosen in combination with services should be well established. How to implement this must be scrutinized by comprehensive research as initiated here. Preliminary results indicate potentials for novel mobile applications.

Practical implications – Contribution to increasing patients' safety by developing mobile solutions to support health care. Those may also contribute to cost savings in health care.

Social implications – Health care experiences an increasing significance for Western industrialized countries because of demographic developments. Care generally shifts from inpatient to outpatient settings; the global shortage of qualified nurses becomes even more prevailing. More support, among others by IT and enhanced interprofessional communication, is demanded for an improved quality and efficiency of care processes.

Originality/value – Mutual approach benefits from the partner's understanding of complex interactions among clinicians, health services, and patients: the ability to design, monitor, and evaluate research strategies integrating care (information) needs is invaluable when applying creative technology solutions within health care domain.

Since the publication of the report of the Lancet Commission on Brandy and the prosecutions that followed, much attention has been given to the subject, and although no great additions to our knowledge of the composition of this spirit have recently been made, practical use is now being made of information which has been at our disposal for five years or more, which has already had far‐reaching effects upon the trade.

This research paper aims to explore how secondary school-aged business owners utilise social media to engage in informal learning. The authors make use of the concept of a self-directed experiential learning cycle to empirically explore adolescents’ entrepreneurial learning processes without formal guidance or curriculum.

The study adopts a one-on-one interview approach with a critical incident technique in interviewing to examine the experiences of 10 Grade 9–11 business owners who run social media-based businesses on Instagram.

The results demonstrate that student business owners were able to capitalise on social media for venture creation and informal learning. They effectively engaged in experiential learning cycles with active help-seeking and mentorship in response to challenges in their business journey. A variety of resources within social media, their social circle and the internet were employed by students, highlighting the role the self-directed element plays in their experiential learning process.

The research urges institutions to recognise the potential of informal learning on social media and offer more support to strengthen students’ learning.

This research represents the first exploratory study on the potential of school-age teens’ self-initiated informal entrepreneurial learning while testifying the theory of the self-directed experiential learning cycle in the context of social media businesses. The study offers novel insights into the fields of students’ informal learning, entrepreneurial learning and social media learning.

The purpose of this paper is to provide a conceptual tool that would help managers to integrate the findings from strategy frameworks such as the value chain, the five forces or the VRIO framework by jointly analyzing the different levers of competitive advantage.

Building on the extant literature the paper develops a strategy framework that integrates the internal and external dimensions of strategy formulation. To illustrate a practical application of the value‐process framework, the paper presents a case study of a project at the German music corporation Sony BMG.

The value‐process framework serves managers as a conceptually unifying analysis tool that contributes to their understanding of the main levers that help to create a sustainable competitive advantage. The framework can be used to visually integrate isolated strategy frameworks by jointly analyzing the different levers of competitive advantage, and to develop consistent and integrated strategies that simultaneously take into account the internal and external perspectives of strategic decision making.

While the existing strategy literature is good at providing specific concepts and tools of strategy analysis, it rarely connects the different dimensions and points out their interdependencies. As a result, strategic analyses are often fragmented and isolated from their broader context. The value‐process framework aims to provide an overarching perspective that helps to integrate the different dimensions of strategy formulation.

The Maastricht process sets up economic and fiscal criteria that member states of the European Union are expected to meet in the preparation for and when having joined the third stage of Economic and Monetary Union (EMU). According to EMU rules, the Commission monitors the fiscal behavior of the participants but member states themselves-as members of the Council of Ministers-finally vote on the Commission recommendations. It is therefore questionable whether these criteria actually constrain member states from running excessive deficits. This paper adopts a constitutionalist perspective to address this question by asking how member states will interpret or even change the fiscal rules of the EMU in the future. Council decision-making in the area of EMU politics is analyzed using data on the fiscal positions of old and new member states of the European Union. The findings suggest that the recent enlargement will shift policy outcomes, but, if compared to the situation at the time of the signing of the Maastricht treaty, the effect is rather marginal.
