Shaping the firm's external search strategy

2014

This paper explores the determinants of external knowledge search strategies, specifically, exploitative and exploratory search. The literature emphasizes environmental context and technological resources, especially R&D, as important determinants of the search strategy. In this paper we focus on two types of the firm's formal structure: formalized and decentralized structures. The study uses survey data from the ceramic tile industry in Spain. The results show that a competitive environment and a decentralized organizational structure play a role in shaping the firm's external search strategy, but that R&D has no effect. We find that competition inhibits exploratory search, while a decentr…

Individual Decisions and Perceived Form in Collective Free Improvisation

2015

International audience; This paper proposes a first attempt to study quantitatively Collective Free Improvisation (CFI). We report an experiment designed to study the relationship between the improvisers’ individual high-level decisions and the improvisation’s form perceived by external auditors. We recorded 16 trios in which the improvisers used a MIDI-pedal to indicate in real-time a significant change in their own musical production. Expert listeners were later asked to segment each improvisation so that we obtained their perception of the structure. By analysing the correlations between musicians’ individual decisions and listeners’ segmentation points, we discuss how the improvisation’…

Psychometric properties of the Spanish version of the Temporal Satisfaction with Life Scale (TSLS): A study on elderly attending to university progra…

2015

Several measures have been developed for the operalization of well-being, standing out the Satisfaction With Life Scale (SWLS). To cope with some of its problems the Temporal Satisfaction with Life Scale (TSLS) was developed. The aim of this study is to present and validate the Spanish version of the TSLS, in a sample elderly attending to University programs. The sample was composed of 737 elderly. Together with the TSLS, an indicator of general life satisfaction and the SF-8 Health Scale were used. Analyses included the study of factorial validity, estimations of reliability and external validity. Results of the confirmatory factor analysis were adequate: χ2(87)=454.593 (p<.001), CFI=.9…

Climate change is a major challenge for sustainable development, impacting human health, wellbeing, security, and livelihoods. While the post-2015 development agenda sets out action on climate change as one of the Sustainable Development Goals, there is little provision on how this can be achieved in tandem with the desired economic progress and the required improvements in health and wellbeing. This paper examines synergies and tensions between the goals addressing climate change and economic progress. We identify reductionist approaches in economics, such as ‘externalities’, reliance on the metric of the Gross Domestic Product, positive discount rates, and short-term profit targets as som…

Exploring the feasibility of introducing electric freight vehicles in the short food supply chain: A multi-stakeholder approach

2021

Abstract The transition towards more sustainable approaches in the Food Supply Chain was concretely visible in the implementation of alternative models, like the Short Food Supply Chain. Some authors raise doubts on the environmental impact of this model, in particular for the externalities caused by the transport system, suggesting the adoption of Electric Freight vehicles. By adopting a multi-stakeholder approach, the objective of this study is to explore both the barriers and potentialities involved in the adoption of Electric Freight vehicles in the Short Food Supply Chain, and the existence of a shared strategy at the system level able to foster their adoption. Results suggest that, fo…

PAYMENT FOR ENVIRONMENTAL SERVICES FOR THE SUSTAINABLE DEVELOPMENT OF THE TERRITORY

2014

Over the last years the interest in environmental s ervices provided by forests has considerably grow. This situation, in developed countries, derive from risi ng demand of new goods and services tied to landsca pe use and leisure activities. These can be considered such as no woody products and they represent externalities produced by forest that, if suitably utilized, could produce value for the area and earn ings for people living near forests. From an economic point of view, at the aim of providing these services, it is necessary the introduction of a suitable payment sy stem or, in alternative, a situation in which posit ive externalities of landscape, in sync with other good s/service…

Environmental pollution, sustained growth, and sufficient conditions for sustainable development

2016

Abstract Sustainability and optimality are the two main issues discussed in environmental economics and economic growth theory. This paper studies economic growth in the presence of two environmental externalities. The first one is local and gives account of the marginal damage from the emissions flow. The second one is aggregate, or global, and relates to the extreme damage which may happen if the accumulated stock of pollutants is on the threshold of a worldwide catastrophe. In this context, the decentralized equilibrium is inefficient and economic growth unsustainable. However, we find and completely characterize the socially optimal equilibrium, which shows that sustained growth is feas…

Who Is the Social Entrepreneur?

2021

Social entrepreneurs are understood as individuals integrated within a society, being continually influenced by the environment. This chapter explains that the constitution of a social entrepreneur is determined by external variables (environmental influences) and internal variables (characteristics of the individual). Among the external influences, we should highlight the Triple Bottom Line phenomenon, the Corporate Social Responsibility trend, technological advances and the Sustainable Development Goals. The intrinsic motivators would be divided into three different dimensions: attitude and intention, personality traits and leadership skills. The synergies produced as a consequence of the…

Promoting sustainable environmental practices amongst automobile consumers: an evaluation of the impacts of pursuing innovations in tax regulations

2012

The growing importance of environmental sustainability has resulted in governments pursuing innovative regulatory changes in order to achieve this goal. The aim of this paper is to evaluate critically whether pursuing innovative regulations in the realm of environmental taxation have elicited more sustainable practices amongst automobile consumers in Spain. The finding is that the tax innovations of the Spanish government that seek to internalise externalities, namely the registration tax and fuel tax, but not the annual circulation tax, are leading automobile consumers to pursue more environmentally sustainable practices, and are also resulting in the automotive sector itself pursuing inno…

Determination of consensus kQ values for megavoltage photon beams for the update of IAEA TRS-398

2020

The IAEA is currently coordinating a multi-year project to update the TRS-398 Code of Practice for the dosimetry of external beam radiotherapy based on standards of absorbed dose to water. One major aspect of the project is the determination of new beam quality correction factors, kQ, for megavoltage photon beams consistent with developments in radiotherapy dosimetry and technology since the publication of TRS-398 in 2000. Specifically, all values must be based on, or consistent with, the key data of ICRU Report 90. Data sets obtained from Monte Carlo (MC) calculations by advanced users and measurements at primary standards laboratories have been compiled for 23 cylindrical ionization chamb…
