Election Campaigning Online
2005
This article presents an integrated quantitative analysis of the functional, formal and content-related aspects of German political party websites during the 2002 National Elections. The analysis is guided by the normalization hypothesis of cyberspace, which infers a transfer of ‘real-world’ features of politics to the Internet. Results provide empirical evidence of a limited normalization in German e-campaigning: indeed, German party websites primarily serve information functions while neglecting interactive features. Yet, no overall gap in professionalism is found between major and minor parties analysed. Finally, online campaigning is dominated by a high level of self-referentiality but…
RISK AVERSION IN THE BOARD ROOM. AN ANALYTICAL APPROACH ON CORPORATE GOVERNANCE OF GERMAN STOCK-LISTED COMPANIES
2016
According to the agency theory, a positive relationship between company performance and good corporate governance should exist. A broader study of the author of this paper examines a sample of German stock-listed companies whereas Germany can be seen as one of the most highly regulated countries concerning corporate governance. The overall purpose of the author’s study is to analyze the effect of supervisory board characteristics and procedures on firm performance. Several corporate governance variables such as number of committees, board independency, supervisory board compensation, personal risk liability, etc. are examined regarding their effects on firm performance in terms of firm grow…
Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS
2010
The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets—given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the sho…
Enterotoxinomics: The omic sciences in the study of staphylococcal toxins analyzed in food matrices
2013
Abstract Foodomics covers all several disciplines related with emerging working areas and relies on them to get a broader knowledge about food quality and food safety to improve consumer's well-being, health and confidence. Enterotoxin-producing S. aureus is one of the most common causes of food-borne human illness throughout the world. Because of the possible significance of these enterotoxins for public health and food safety, greater knowledge of their occurrence and an efficient means of screening at the protein level are needed. It is under these circumstances where Enterotoxinomic science has an important role. The term Enterotoxinomics refers to the omic sciences applied to enterotox…
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 …
Environmental learning in regions: a social capital based approach. The case of Latvia
2016
AbstractHow do people learn about the environment and behave accordingly? What is the cognitive process at the base of this learning mechanism? The present paper is a pilot work investigating the dynamics of individual environmental knowledge on the basis of social capital theory. Using Tsai and Ghoshal’s findings, a well known framework widely accepted in organizational studies which supports the existence of a relationship between structural, relational and cognitive dimensions of social capital, and between social capital and knowledge exchange, these dynamics are then tested in the context of environmental behaviour studies. The quantitative analysis is carried out by means of a structu…
Employer Branding Training Development for Public Organisations
2021
In the condition of demographic issues in Europe and competition for specialist between public and private sector on the labour market public organisations’ as employers’ image is an important aspect of development. The research aim is to identify principles of Employer Branding (EB) and ways public organisations can organize and develop employees’ education on this topic. There are EB activities examined in ten socially responsible (SR) organisations from public sector in Latvia. Authors prepare theoretical bases for the research analysing scientific literature to explain the main point of the approaches framework and define the main terms in depth implementing qualitative and quantitative…
Employees' perceptions of high-performance work systems and innovative behaviour: The role of exploratory learning
2017
Abstract This paper analyses the influence of employees' perceptions of high-performance work systems (HPWSs) on employees' exploratory learning and innovative behaviour. Furthermore, the mediating role of exploratory learning in this relationship has also been studied. To achieve these objectives, a quantitative analysis was conducted with a sample of 304 researchers from the Spanish public sector. Results showed the relevance of employees' perceptions of HPWSs in promoting exploratory learning and employees' innovative behaviour. The mediating role of exploratory learning in the relationship was assessed. The paper mentions the importance of workers' perceptions on the implementation of H…
Slide electrification: charging of surfaces by moving water drops.
2019
We investigate the charge separation caused by the motion of a water drop across a hydrophobic, insulating solid surface. Although the phenomenon of liquid charging has been consistently reported, these reports are primarily observational, results are difficult to reproduce, and no quantitative theory has been developed. In this work, we address both the experimental and theoretical sides of this problem. We reproducibly measure the charge gained by water drops sliding down a substrate, and we outline an analytical theory to describe this charging process. As an experimental system, we choose water drops moving down an inclined plane of glass hydrophobized with perfluoro octadecyltrichloros…
Les études hédoniques soutiennent-elles une valeur verte élevée dans le bâtiment ? Une réponse par la méta-analyse
2018
International audience; La place majeure occupée par le secteur du bâtiment dans la consommation d'énergie (40%) et les émissions de gaz à effet de serre (1/3 des émissions) explique le développement du débat scientifique axé sur la réduction de l'impact environnemental du bâtit et sur ses leviers. Ces dernières années ont notamment vu croitre une littérature considérable relative à la disposition à payer du public pour les bâtiments « verts » labélisés par des écolabels, cette « valeur verte » étant estimée dans la grande majorité des études via des modèles hédoniques. Dans cet article, nous proposons d'offrir une synthèse de ces résultats dans le cadre d'une méta-analyse portant sur plus …
