    Opis:
    This article is part of a larger project on contemporary sources of legitimacy of the European Union. My prior inquiry into this subject argued that the primary legitimacy problem within the EU is not the so-called 'democratic deficit' or the EU's failure to produce certain outputs, but is instead the EU's ability to enact laws against a national government's will and dissent through Qualified-Majority Voting ('QMV') in the Council of Ministers. Based on an analysis of the EU's internal transformation through four successive treaties, that article argued that the EU can be legitimated based on two primary sources, national democracy and European citizenship, such that QMV decision-making could be justified based on promotion or protection of European citizenship, even against a national democracy's will. From this internal transformation of the EU, this article turns to the EU's external transformation through enlargement across Central and Eastern Europe. By examining the process of enlargement, the article argues that this practice also reflects the hypothesized dual legitimacy structure based on European citizenship and national democracy. In particular, the EU's primary focus during the enlargement process on the Copenhagen political criteria (rather than the economic or acquis criteria) - and in particular, ensuring the candidate countries' commitment to EU fundamental rights - was justified in light of the concurrent shift in EU decision-making from de facto unanimity to QMV. Since an EU democracy could now be outvoted in the Council and an EU decision could be taken against a nation's democratic will, the old EU Member States wanted to ensure that the new Member States would share their core political values, such that all Member States would be expected to pursue the same basic shared interests and could thus credibly claim to act on behalf of European citizens. Even as a pre-condition of accession negotiations, the EU required candidate countries to meet stringent political criteria reflecting the EU's new orientation around fundamental rights and excluded those countries that failed to do so, particularly based on human rights grounds; in contrast, it extended membership to countries even if they did not fully meet the economic or acquis criteria. In conclusion, the article proposes to formalize this consensus through a 'Strasbourg Compromise,' mirroring the Luxembourg Compromise that underpinned the European Communities, but orienting it around European citizenship rather than the national veto.

    Opis:
    Aim: Building upon stakeholder and institutional theory, this paper investigates the relationship between product diversification and corporate social performance (CSP), thereby attempting to make essential contributions to the current literature. Based on an extensive literature review, it was expected that related, unrelated and total product diversification are positively related to CSP. Moreover, it was hypothesized that the exposure to weak institutional host country environments negatively affects the relationship between diversification and CSP, and that the Sustainable Development Goals (SDGs) have a positive effect on the relationship. Design / Research methods: The sample selected for this research is the non-renewable energy industry, since the industry shows great divergence in terms of corporate social responsibility (CSR) performance. In addition, the industry is highly susceptible to regulatory changes, while the Sustainable Development Goals have an enormous focus on the reliability and sustainability of energy, making it a highly relevant industry to study. This study analyzed 40 a 40 non-renewable energy firms over a time frame of seven years, by using OLS regression. Conclusions / findings: The results reveal that unrelated diversification is positively related to CSP, while the other forms of diversification show insignificant results. Contrary to expectations, the Sustainable Development Goals negatively affect the relationship between product diversification and CSP, while the moderating effect of exposure to weak institutional environments is insignificant. Originality / value of the article: Research on the relationship between product diversification on corporate financial performance is well-established, but the way in which product diversification influences a firm’s behavior towards stakeholder demands and social concerns remains largely unexplored. Accordingly, the results of this study challenge existing theories while adding more context to the existing relationship, and in turn provide promising avenues for future research.

    Abstract: Aim: This paper investigates how a framework for analysing business sectors in emerging markets looks like when taking into account the local context-dependent and general factors of The Bottom-of-the-Pyramid (BoP). The BoP segment in emerging markets represents a major growth potential for firms, including multinational enterprises (MNEs) from developed countries. However, the continued lack of success of MNEs in these markets has shown that generic one-size-fits-all strategies for the BoP are not appropriate as BoP contexts differ between countries. Design / Research methods: The sample that was selected for the research includes two non-governmental organizations (NGOs) related to the BoP and eight managers at MNEs with activities in the BoP have been interviewed in a semi-structured manner to collect rich data. Conclusion / findings: By interviewing eight managers at MNEs with activities in the BoP and two NGOs related to the BoP, an additional analysis, BoP-orientation, and further extensions to the original analyses are being presented. This results in an advanced framework for analysing business sectors in emerging markets. Originality / value of the article: Current frameworks for analysing business sectors in emerging markets do take into account inter-country differences but fail to recognize intra-country differences, which causes them to fall short on their applicability to the BoP. This paper fills the gap how frameworks for analysing business sectors in emerging markets can be made applicable for the BoP by taking into account both the local context-dependent and general factors of a BoP-market to analyse it for opportunities, threats, and eventually and strategic entry mode.

    Opis:
    Performance analysis of a 1.0 tonne desiccant evaporative cooling storage structure for mango fruits was studied. The study examined the effects of inlet air conditions and water flow rates through an absorber on the cooling performance of the system. The airflow rate was approximately 0.24 m3·s -1 and water flow rates through the absorber varied from 0 to 0.252 l·s -1 . The system produced approximately 7 kW of cooling at water supply rate of 0.252 l·s -1. A simple linear correlation was established for condition line slope from inlet to exiting air conditions for all the water flow rates. Lines of best fit resulted in correlation coefficient better than 0.96. The observed temperatures with a direct evaporative cooler, tested with freshly harvested mango fruits were found to be between 15.1°C and 23.4°C and relative humidity between 81.8% and 97.7%. Physiological weight loss and firmness assessments of the fruits were also conducted.
    Artykuł omawia analizę wydajności chłodni wyparnej o poj. 1,0 tony, wykorzystywanej do przechowywania owoców mango. Zbadano wpływ warunków wlotowych powietrza i szybkości przepływu wody przez pochłaniacz na wydajność chłodniczą systemu. Natężenie przepływu powietrza wynosiło około 0,24 m3·s-1 , a natężenie przepływu wody przez absorber wahało się od 0 do 0,252 l·s-1 . W tym czasie wyprodukowano około 7 kW chłodu przy przepływie wody wynoszącym 0,252 l·s -1 . Określono prostą korelację liniową nachylenia linii wykresu warunków, od wlotu do wylotu powietrza, dla wszystkich wielkości przepływu wody. Linie o najlepszym dopasowaniu dały współczynnik korelacji powyżej 0,96. Zaobserwowane temperatury chłodni wyparnej, sprawdzane na świeżo zebranych owocach mango, wynosiły od 15,1°C do 23,4°C, a wilgotność względna od 81,8% do 97,7 %. Dokonano również oceny fizjologicznej utraty masy i jędrności owoców.

    Opis:
    Despite the growing importance of electronic reversed auctions (ERAs) few empirical studies have explored the appropriateness of ERA usage. Most commonly, transaction cost theory has been used for these ERA-studies, relying on arguments that consider asset specificity as the primary explanation for organizational boundaries. We seek a more thorough explanation for perceived Electronic Reverse auctions (ERA) appropriateness, using multiple theoretical perspectives. This study includes insights and variables from the incomplete contract theory and the resource dependence theory. A conceptual model for ERA appropriateness was developed from the buyer perspective. This model was empirically validated using a survey of 176 purchasing professionals. The findings suggest a positive impact of buyer power on ERA appropriateness, while total interdependence does not appear to affect ERA appropriateness. The results further indicate that asset specificity stimulates ERA usage. ERA-minded purchasers consider ERAs as a tool for exploiting buyer power and for imposing relationship investments on suppliers. At the same time, variables related to collaboration do not appear to be important for ERA appropriateness from the perspective of the buyer. Suppliers are required to make relation-specific investments, but are not valued for their relational efforts. The novelty of this article Scholars have taken several approaches to investigate and to explain company’s sourcing decisions that include ERA use. We address an important gap in the literature by using the incomplete contract theory in combination with the resource dependence theory to provide a better understanding of buyers’ perceived ERA appropriateness.

    Opis:
    APEX (Airborne Prism EXperiment) is a high spectral and spatial resolution hyperspectral sensor developed by a Swiss-Belgian consortium on behalf of the European Space Agency. Since the acceptance of the instrument in 2010, it has been operated jointly by the Flemish Institute for Technological Research (VITO, Mol, Belgium) and the Remote Sensing Laboratories (RSL, Zurich, Switzerland). During this period, several flight campaigns have been performed across Europe, gathering over 4 Terabytes of raw data. Following radiometric, geometric and atmospheric processing, this data has been provided to a multitude of Belgian and European researchers, institutes and agencies, including the European Space Agency (ESA), the European Facility for Airborne Research (EUFAR) and the Belgian Science Policy Office (BelSPO). The applications of APEX data span a wide range of research topics, e.g. landcover mapping (mountainous, coastal, countryside and urban regions), the assessment of important structural and (bio)physical characteristics of vegetative and non-vegetative species, the tracing of atmospheric gases, and water content analysis (chlorophyll, suspended matter). Recurrent instrument calibration, accurate flight planning and preparation, and experienced pilots and instrument operators are crucial to successful data acquisition campaigns. In this paper, we highlight in detail these practical aspects of a typical APEX data acquisition campaign.

    Opis:
    Lycopene, the pigment principally responsible for the red color of tomatoes, is well-known for its strong antioxidant property and substantial health benefits. In this study, the optimal combination of factors for lycopene extraction from tomato pomace was identified using response surface methodology. The best practically feasible results maximizing both lycopene yield and antioxidant activity of the extract were obtained by applying a ratio of ethyl acetate to tomato waste of 35:1 (v/w), at a temperature of 55ºC for 100 min of extraction. The extract was then added to the peanut oil to evaluate its oxidative stability during 60 days of storage at 40ºC. It was shown that the addition of 2 g extract/kg oil offered the lowest level of peroxide value, p-anisidine value, and total oxidation value, followed by the oils with 50 mg butylated hydroxytoulene/kg oil and 1 g extract/kg oil, indicating the effect of lycopene-rich extract on enhancing the oxidative stability of peanut oil. The results in this study suggest that incorporation of extract rich in lycopene from tomato waste products may be an effective method to reduce oxidation and extend the shelf-life of peanut and other vegetable oils.

    Objectives This study aimed at investigating cross-sectional relationships between psychosocial characteristics of work and presenteeism in a sample of Belgian middle-aged workers. Material and Methods Data were collected from 1372 male and 1611 female workers in the Belstress III study. Psychosocial characteristics assessed by the use of self-administered questionnaires were: job demands, job control, social support, efforts, rewards, bullying, home-to-work conflict and work-to-home conflict. Presenteeism was measured using a single item question, and it was defined as going to work despite illness at least 2 times in the preceding year. Logistic regression models were used to investigate the relationship between psychosocial characteristics and presenteeism, while adjusting for several socio-demographic, health-related variables and neuroticism. An additional analysis in a subgroup of workers with good self-rated health and low neuroticism was conducted. Results The prevalence of presenteeism was 50.6%. Overall results, adjusted for major confounders, revealed that high job demands, high efforts, low support and low rewards were associated with presenteeism. Furthermore, a significant association could be observed for both bullying and work-to-home conflict in relation to presenteeism. The subgroup analysis on a selection of workers with good self-rated health and low neuroticism generally confirmed these results. Conclusions Both job content related factors as well as work contextual psychosocial factors were significantly related to presenteeism. These results suggest that presenteeism is not purely driven by the health status of a worker, but that psychosocial work characteristics also play a role.

    Objectives The Health Impact Assessment (HIA) was conducted to evaluate the potential community health implications of a proposed oil drilling and production project in Hermosa Beach, California. The HIA considered 17 determinants of health that fell under 6 major categories (i.e., air quality, water and soil quality, upset conditions, noise and light emissions, traffic, and community livability). Material and Methods This paper attempts to address some of the gaps within the HIA practice by presenting the methodological approach and results of this transparent, comprehensive HIA; specifically, the evaluation matrix and decision-making framework that have been developed for this HIA and form the basis of the evaluation and allow for a clear conclusion to be reached in respect of any given health determinant (i.e., positive, negative, neutral). Results There is a number of aspects of the project that may positively influence health (e.g., increased education funding, ability to enhance green space), and at the same time there have been potential negative effects identified (e.g., odor, blowouts, property values). Except for upset conditions, the negative health outcomes have been largely nuisance-related (e.g., odor, aesthetics) without irreversible health impacts. The majority of the health determinants, that had been examined, have revealed that the project would have no substantial effect on the health of the community. Conclusions Using the newly developed methodology and based on established mitigation measures and additional recommendations provided in the HIA, the authors have concluded that the project will have no substantial effect on community health. This approach and methodology will assist practitioners, stakeholders and decision-makers in advancing the HIA as a useful, reproducible, and informative tool.
