Business-to-Business e-commerce adoption and perceived benefits: evidence from small and medium Spanish enterprises

2009

This paper focuses on the factors affecting Business-To-Business (B2B) e-commerce adoption and the perceived benefits for Small and Medium-sized Enterprises (SMEs). We propose and test a model that analyses the influence of firms' previous experience and environmental factors on e-B2B adoption and the effects of e-B2B adoption on the perceived benefits and the intention to continue adopting B2B. Our results show that the more e-B2B is used in SMEs, the higher the level of perceived benefits and this, in turn, has a positive influence on the intention to continue doing B2B e-commerce. Managerial implications of these findings are also discussed.

Assessment of Dietary Intake of Vitamin K and Maximum Limits for Vitamin K in Food Supplements

2019

The Norwegian Scientific Committee for Food and Environment (Vitenskapskomiteen for mat og miljø, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), evaluated the intake of vitamin K in the diet. VKM has also assessed the consequences of establishing maximum limits for vitamin K in food supplements at 100, 200, 300, 600 or 800 µg/day. The former maximum limit for vitamin K of 200 µg/day in food supplements was repealed 30 May 2017.
 Vitamin K is a fat-soluble vitamin required for the carboxylation of glutamic acid residues in proteins that regulate blood coagulation and bone metabolism. The naturally occurring forms of vitamin K present in food and sup…

A job-exposure matrix for research and surveillance of occupational health and safety in Spanish workers: MatEmESp

2013

BACKGROUND: In this study we describe a general-population job-exposure matrix (MatEmESp) for Spanish workers covering the period 1996-2005. METHODS: The Finnish job-exposure matrix (FINJEM) provided the default value estimates for occupational exposure to chemical, physical and biological agents. These estimates were adapted to Spanish working conditions by local experts. Spanish surveys were used to obtain exposure estimates for ergonomic and psychosocial risk factors. Employment and socio-demographic conditions for Spanish workers were obtained from the Spanish National Statistics Institute. RESULTS: MatEmESp provides a large amount of national and occupation-specific data on the major o…

Transferability to LDC of Some European standards concerning the environmental certification of products and services

2002

Goal and Scope. Western developed countries (DC) are currently involved in an important process of releasing new rules and standards devoted to the environmental certifications of urban systems, in order of accomplishing the requirements established by the international protocols (Kyoto, among them), aimed at the reduction of greenhouse gases emitted in the atmosphere and at the limitation of the environmental impact as well. Within this frame, the European Union is giving a rising importance to the so-called 'Integrated Product Policy' (IPP), that is an integrated approach of the environmental policy, aiming to an improvement of the environmental performance of products and services during…

Sustainable integration of Renewable Energy Systems in a Mediterranean island: a case study

2013

Starting from a previous technical and economical feasi-bility study, this paper analyzes the integration of Renewable Energy Sources into an existing territory with specified features of the natu-ral landscape and of the built environment. The work puts into evi-dence that territories development must use suitable tools and rules based on integrated knowledge, since technical feasibility studies do not assess the sustainability of the proposed infrastructures within the built environment and landscape. The studied system is in the is-land of Pantelleria situated between Sicily and northern Africa.

Food safety risk analysis from the producers' perspective: prioritisation of production process stages by HACCP and TOPSIS

2018

[EN] From the manufacturers perspective, the Hazard Analysis and Critical Control Point (HACCP) system nowadays represents the mainly way to implement the food safety risk management in food industries. Nevertheless, the identification and prioritization of hazards as the outcome of the first principle of HACCP is not sufficient to identify production process stages that more significantly and critically contribute to the consumer¿s risks. With this recognition, the present paper proposes a Quantitative Risk Assessment (QRA) approach based on HACCP and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to individuate production process phases on which implementing co…

“The risk of age”? Early detection test, prostate cancer and practices of self

2010

Abstract Drawing on Rose and Novas’s concept of “biological citizenship” and Michel Foucault's "practices of self", this paper reflects on how men become agents of their own therapeutic regimens, and yet internalise messages of risk and practices of self within early detection of prostate cancer discourses in the late 20th century. In doing so, it traces the ways in which concepts of age, gender and risk converge at the problematic site of prostate cancer and preventative health strategies, both of the state and the medical profession. Analysing how insecurities have simultaneously resulted in over-promoting and over-diagnosing risk, thereby blurring the lines between normal and pathologica…

Phantomuntersuchung zur Optimierung der Spiral-CT und 3 D-Rekonstruktion des Tracheobronchialsystems

1996

PURPOSE To optimise three-dimensional spiral CT of the tracheobronchial tree using adequate acquisition and reconstruction parameters for spiral CT of the chest. MATERIAL AND METHODS Qualitative and quantitative assessment of different 3 D reconstructions of two test objects of the tracheobronchial tree depending on section thickness, reconstruction interval, pitch, and reconstruction algorithm used in spiral CT (Siemens, Somatom plus S) of the chest. The frequency of volume and stairstep artifacts was evaluated. The 3 D reconstructions were generated using a seeded VOI-technique (Allegro, ISG). RESULTS Reduction of artifacts was achieved by decreasing section thickness. Increasing overlap …
