Diffusion of forest biorefineries in Scandinavia and North America
2012
Abstract Biomass-based energy has become a major focus of attention from a variety of directions due to the global challenges of meeting our energy needs. Bioenergy and bio-products are also currently being explored intensively in the forest cluster, as many elements that have in the past guaranteed success have largely disappeared. As the bioenergy and biorefining economies are evolving, there is a need for realistic estimates regarding the factors which affect the diffusion of forest biorefineries. This paper outlines global and national drivers for forest biorefineries in Scandinavia and North America. It explores the financial, political, technological, and ecological and raw-material r…
DESIGN THINKING MODELS IN DESIGN RESEARCH AND EDUCATION
2016
Design thinking has become a paradigm that is considered to be useful in solving many problems in different areas: both in development of design projects and outside of traditional design practice. It raises the question - is design thinking understood as a universal methodology in all cases? How it is interpreted in design education? The analysis of theoretical and design related literature indicates different basic and contextual challenges facing design today: increasing scale of social, economic and industrial borders; complexity of environment and systems; requirements in all levels. As specialists and researchers in the field of design have concluded, here are multiple disconnects b…
Assessing land condition as a first step to achieving land degradation neutrality : A case study of the Republic of Srpska
2018
Abstract Land Degradation Neutrality (LDN) is a key voluntary and aspirational target of Sustainable Development Goal (SDG) 15 which urges countries to protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss. A first and critical important step in the implementation of LDN is assessing the current land condition using not only active restoration of degraded land, but also targeting land degradation drivers behind the land degradation process. In a first step to achieve these goals, countries were provided a global dataset for three sub-indicators of land degra…
Employees’ challenges and needs for reskilling when working with software robots
2022
Software robots are becoming increasingly adopted in different industries. The growing rate of automatization will affect more and more people and will result in changes in businesses of all sizes. Impacts can be observed at both the organizational and individual employee levels. A growing number of studies of software robots’ advantages and disadvantages on an organizational or industry-specific level have been carried out. However, there is limited knowledge about the employees’ perceptions of challenges and new skills needed when working with software robots. This study addresses this gap by using open-ended questionnaire responses from employees who have worked with software robots. Thi…
Different profile and distribution of antigen specific T cells induced by intranasal and intrarectal immunization with rotavirus 2/6-VLP with and wit…
2013
International audience; In this study, we compared both the profile and distribution of antigen specific primed T cells after intrarectal (IR) and intranasal (IN) immunization with rotavirus (RV) 2/6-VLP, alone or in the presence of LT-R192G, in order to highlight the differences between the two routes and the impact of the adjuvant. Adult BALB/c mice were immunized once with 2/6-VLP with or without adjuvant and the T cell response was analyzed in lymphoid tissues after in vitro restimulation with the antigen. IN, but not IR, immunization of mice with 2/6-VLP alone induced antigen-specific IL-10 and IL-17 secreting T cells. IL-10-, in contrast to IL-17-, secreting T cells did not migrate to…
The Valencia Eustress-Distress Appraisal Scale (VEDAS): Validation of the Italian Version
2018
© 2018 by the authors. The aim of this study is to validate the Italian version of the Valencia Eustress-Distress Appraisal Scale (VEDAS). Two hundred and thirty-two Italian workers were involved in the study. Dimensionality, reliability, and concurrent validity were analyzed. Confirmatory factor analysis supported a four-dimensional structure. In addition, the Italian version of the scale showed good internal consistency and validity. The results indicate that the Italian version of the VEDAS is a valid instrument for measuring eustress and distress appraisal in the Italian context. ispartof: SUSTAINABILITY vol:10 issue:11 status: published
A Dynamic Attribute-Based Authentication Scheme
2015
Attribute-based authentication (ABA) is an approach to authenticate users by their attributes, so that users can get authenticated anonymously and their privacy can be protected. In ABA schemes, required attributes are represented by attribute trees, which can be combined with signature schemes to construct ABA schemes. Most attribute trees are built from top to down and can not change with attribute requirement changes. In this paper, we propose an ABA scheme based on down-to-top built attribute trees or dynamic attribute trees, which can change when attribute requirements change. Therefore, the proposed dynamic ABA scheme is more efficient in a dynamic environment by avoiding regenerating…
Study of Wine Producers’ Marketing Communication in Extreme Territories–Application of the AGIL Scheme to Wineries’ Website Features
2020
This study measures the communication ability of wineries in two extreme territories of Southern Italy, Mount Etna and the island of Pantelleria. The evaluation of four dimensions of web communication was carried out by the AGIL Scheme (i.e., adaptation, goal-attainment, integration, latent pattern maintenance). The study provides a generalizable model to be applied in other similar studies. Additionally, focus groups of experts were carried out. The method proved to be suitable to measure the communication effectiveness of wineries through websites. Extreme territories may add value to the wine, regardless of the brand. The heroic wines may become the symbol of these territories, helping e…
International Study of Asthma and Allergies in Childhood (ISAAC) fase II: metodología y resultados de participación en España
2001
Antecedentes: La fase I del ISAAC ha proporcionado información muy valiosa sobre la prevalencia mundial de asma y alergia en la infancia. Objetivos: Describir la puesta en marcha de la fase II del estudio y la participación de niños normales en cada una de las pruebas que se realizan, en las cuatro ciudades participantes en España, y establecer en Cartagena, qué influencia puede tener el tipo de colegio o la localización (área contaminada o no). Métodos: En su fase II, el ISAAC incluye cuestionario de síntomas y de factores de riesgo y tratamiento, examen de piel, prick-test cutáneo, prueba de provocación bronquial, determinación de inmunoglobulina E (IgE) total y específica, y medición de …
Introducing the BICA Society
2010
The Biologically Inspired Cognitive Architectures Society, or the BICA Society, is a recently formed nonprofit organization. The purpose of the Society is to promote and facilitate the transdisciplinary study of biologically inspired cognitive architectures (BICA), in particular, aiming at the emergence of a unifying, generally accepted framework for the design, characterization and implementation of human-level cognitive architectures. The First International Conference on Biologically Inspired Cognitive Architectures (BICA 2010) is at the same time officially the First Annual Meeting of the BICA Society.
