Analysis of Social Media Impact on Opportunity Recognition. A Social Networks and Entrepreneurial Alertness Mixed Approach
2020
This paper investigates the effects of social media on entrepreneurial opportunity recognition. Combining the internal and external approaches of opportunity recognition, the study analyzes how social media influences the entrepreneurs in discovering new entrepreneurial opportunities. Structural equation modeling was used in this study, using the variance-based partial least squares (PLS)&ndash
Bricolage in the marketing efforts of a social enterprise
2016
Purpose The paper aims to understand how resource constraints are addressed in the development of a marketing strategy by a social enterprise. Design/methodology/approach The authors have used an in-depth case study of collaboration between a Finnish university and an Indian social enterprise as the methodology for the research in which the data were collected over a period of two years. The data involve semi-structured interviews, field notes and student reports. Findings The authors propose bricolage as a method of marketing ingenuity in resource-constrained social enterprises. Network bricolage and entrepreneurship education bricolage were identified as two mechanisms adopted to address…
Competitiveness and Sustainability in tourist firms and destinations
2020
Tourism is a major activity in the global economy, not only in terms of its economic impact but also its social and environmental implications. The management practices and processes adopted by tourist companies and destinations are very heterogeneous and have variable impacts on the triple-bottom-line sustainability (people, profit, planet) of the ecosystem. However, there is still only limited available knowledge about the value of different practices for promoting both sustainable development and greater competitiveness. This Special Issue includes papers that present new ideas, theories, advancements, experiences, evidence or methodologies that support the convergence of economic, socia…
Energy and environmental assessment of retrofit actions on a residential building
2014
Energy and environmental performances of buildings strictly depend on many factors related to the choice of construction materials, technical equipment, installation and use. In the following chapter a set of retrofit actions to improve the thermal performance of an existing conventional building is presented. The energy and environmental assessment of these actions is carried out following a life cycle approach. The embodied energy and the environmental impacts arisen from the production, transportation and installation phases of the required materials and components are calculated. Further, energy saving and environmental benefits and drawbacks concerning the assessed retrofit actions are…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
1996
Resumen basado en el de la publicación Resumen en inglés La evolución histórica del principio de Le Chatelier está relacionada con su uso en el aula de química. La aparente simplicidad en la cual el principio de Le Chatelier fue formulado por primera vez y el éxito logrado en la implementación de algunos procesos industriales importantes le dio un reconocimiento inicial que aún perdura. Sin embargo, desde el comienzo de este siglo, diferentes autores han señalado el carácter limitado de la regla cualitativa y su formulación vaga y ambigua. Además, la termodinámica dada por el Principio de Le Chatelier en algunas formulaciones cuantitativas limitan su aplicabilidad. Sin embargo, la mayoría d…
A Survey of Some Arithmetic Applications of Ergodic Theory in Negative Curvature
2017
This paper is a survey of some arithmetic applications of techniques in the geometry and ergodic theory of negatively curved Riemannian manifolds, focusing on the joint works of the authors. We describe Diophantine approximation results of real numbers by quadratic irrational ones, and we discuss various results on the equidistribution in \(\mathbb{R}\), \(\mathbb{C}\) and in the Heisenberg groups of arithmetically defined points. We explain how these results are consequences of equidistribution and counting properties of common perpendiculars between locally convex subsets in negatively curved orbifolds, proven using dynamical and ergodic properties of their geodesic flows. This exposition…
How does the age structure of worker flows affect firm performance?
2016
We develop a method for decomposing firm performance to impacts coming from the inflows and outflows of workers and apply it to study whether older workers are costly to firms. Our estimation equations are derived from a variant of the decomposition methods frequently used for measuring micro-level sources of industry productivity growth. By using comprehensive linked employer–employee data, we study the productivity and wage effects, and hence the profitability effects, of the hiring and separation of younger and older workers. The evidence shows that the separations of older workers are profitable to firms, especially in the manufacturing ICT-industries. To account for the correlation of …

Spain and the international scientific conferences on polio, 1940s-1960s
2010
The development of international health from a historical point of view has undergone major advances in recent times and constitutes a substantial part of the current agenda for historians of medicine. Within this framework, and focussing on a specific case study (international responses to poliomyelitis outbreaks in the 20th century), we explore the main actions and achievements of agencies such as the WHO and other private and international scientific organizations. Furthermore, this paper seeks to identify the Spanish presence and absence in these activities, their causes and consequences.
