On approximate system dynamic
1996
In this paper concepts and techniques from system theory are used to obtain state-space (Markovian ) models of dynamic economic processes instead of the usual VARMA models. In this respect the concept of state is reviewed as are Hankel norm approximations,and balanced realizations for stochastic models. We clarify some aspects of the balancing method for state space modelling of observed time series. This method may fail to satisfy the so-called positive real condition for stochastic processes. We us a state variance factorization algorithm which does not require us to solve the algebraic Riccati equation. We relate the Aoki-Havenner method to the Arun - Kung method.
EXPLORING 35-44 YEAR OLD MEN’S HEALTH BEHAVIOUR: A QUALITATIVE PERSPECTIVE
2017
Upon reaching 35-44 year of age, men experience their first health problems, often because of an unhealthy way of life e.g., smoking, physical inactivity, unhealthy nutrition habits, etc. In comparison with other age groups, these men rarely look for medical help, thus, opening themselves up to a number of potentially negative consequences e.g. health risks in future. This study explores the health behaviour of 35-44 year old men by conducting semi-structured in-depth interviews with 48 participants. The data are further analysed using inductive thematic analysis. Results indicate the presence of three main types of men’s behaviour: 1) participants with positive attitude towards one’s healt…
Reporting heterogeneity in health: an extended latent class approach
2012
This article explores how individual socio-economic characteristics affect unobserved heterogeneity in self-reporting behaviour and health production using a multivariate finite mixture model. Results show a positive relationship between objective and subjective observable health indicators and true health and support the existence of self-reporting bias related to socio-economic characteristics and individual life styles.
The Sociocultural Basis for Innovation
2018
This chapter argues how economic behaviour in geography could be understood as historically anchored varieties of practice. Contemporary European patterns replicate deep anthropological dispositions as suggested by authors like Geert Hofstede and Emmanuel Todd, and substantiated by Duranton et al. (Types and the persistence of regional disparities in Europe. Economic Geography, 85(1), 23–47, 2009). Old, formative schemes are still operating and new institutional forms, be they cultural, economic or political, are conditioned by their mechanisms. This also goes for innovation. However, in the field of innovation policies, culturally explained variations, cleavages and mismatches are translat…
Interest, Voluntary Associations and the Stability of the Political System
1985
In this article the adequacy of the sociological paradigm in voluntary associ ations' research is investigated by comparing it with its nval, the incor poration or system integration paradigm (types 1 and 2) and with two approaches that are their combinations: multi-dimensional theones of disper sion and cross-cutting of interests (type 3) and multi-dimensional theories of incorporation and system integration of interests (type 4). I express the view that by themselves both pluralism and incorporation paradigms are , unable to depict the complex system of political stability. An adequate theory must contain elements of two dimensions of maintaining stability: firstly, the idea of dispersion…
Human CD8+ memory and EBV-specific T cells show low alloreactivity in vitro and in CD34+ stem cell–engrafted NOD/SCID/IL-2Rγcnull mice
2013
Current strategies in cellular immunotherapy of cancer and viral infections include the adoptive transfer of T cell receptor (TCR) and chimeric antigen receptor engineered T cells. When using transient RNA expression systems in clinical studies, multiple infusions with receptor-redirected T cells appear necessary. However, in allogeneic hematopoietic stem-cell transplantation, repeated transfer of donor-derived T cells increases the risk of alloreactive graft-versus-host disease. We investigated naive-derived (T N ), memory-derived (T M ), and Epstein Barr virus-specific (T EBV ) CD8 + T cell subsets for alloreactivity upon redirection with RNA encoding a cytomegalovirus-specific model TCR.…
Nonverbal immediacy and cognitive learning: A cross‐cultural investigation
1996
The current research was based on data drawn from the cultures of Australia, Finland, and Puerto Rico as well as the dominant United States culture. The direction of the relationship between immediacy and perceived cognitive learning did not differ among the cultures studied (a very positive relationship exists within each culture). However, the magnitude of the relationships varied substantially. The results support the theory that in highly immediate cultures the expectations for immediate teacher behavior are very high and violations of those expectations by being less immediate may be very detrimental to cognitive learning. On the other hand, in less immediate cultures where expectation…
The Post-entrepreneurial University: The Case for Resilience in Higher Education
2021
AbstractHistorically speaking, the university has been a highly resilient organizational form; however recent pressures to become entrepreneurial threaten the institutional foundations on which that reliance is based. The chapter first provides conceptual clarity by revisiting what we argue are two distinct schools of thought on the entrepreneurial university. We show how the economic school’s conception intertwines with the rise of New Public Management (NPM) in Europe in the late 1990s and early 2000s, reframing the concept in ways that made it incompatible with resilience thinking. However, we argue that by tying back into ‘lost’ elements of sociological school’s conception, and associat…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
Resumen basado en el de la publicación Este trabajo está fundado en una concepción constructivista del aprendizaje de las ciencias, más concretamente en el modelo conocido como enseñanza aprendizaje como investigación orientada. De acuerdo con esta base teórica, los autores han desarrollado una investigación empírica enmarcada dentro de la enseñanza de la electroestática en educación secundaria. Los modelos desarrollados permiten valorar el aprendizaje logrado por los estudiantes. De acuerdo con los resultdos podría decirse que los materiales desarrollados y la forma en que se ha trabajado con ellos han contribuido a un aprendizaje más significativo y ha favorecido una actitud más positiva …
Let the best story win : evaluation of the most cited business history articles
2017
Faced with intensifying competition for scientific impact measured in terms of citation counts, small disciplines are challenged to prove their importance as they lack the critical mass to accumulate large numbers of citations. This paper demonstrates that by emphasizing theoretical and methodological rigor even small disciplines such as business history can be competitive. Yet it still appears that readers of business history articles first and foremost seek interesting and useful subject matter, i.e. ‘best’ stories that can be used as background information and as tools in comparisons. However, articles advancing theory and methodology have increasingly gained interest and citations from …
