Agency as the Ability and Opportunity to Participate in Evaluation as Knowledge Construction
2011
School communities find themselves within an overall ideological and epistemological controversy with regard to a drive for goal-oriented and ‘evidence-based’ practices on the one hand and emancipative bottom-up developmental strategies on the other, treating empirical data as information to be analysed according to context, with potential meaning for practice. This raises questions of democratic purposes of education, of leaders' and teachers' agency and corresponding accountability. This article is therefore an empirically based discussion of the relationship between multiple understandings of democracy and multiple practices of evaluation. It presents certain results of three ethnographi…
Corporate Governance Mechanisms for Monitoring or Empowering CEOS? A Study of Chinese Listed Firms
2008
This study examines the impact of governance mechanisms in monitoring or empowering top executives on firm performance. We distinguish between two competing theories, namely agency theory and stewardship theory, which hold conflicting assumptions about CEOs behaviour and hence offer different recommendations concerning corporate governance structure. We conduct an empirical study based on 837 publicly listed companies in China over the period of 2005-2007, the findings of this study provide strong support for stewardship theory. The results suggest that governance mechanisms that can empower CEOs work better in the Chinese context, specifically, a longer CEO tenure and lower board independe…
An overview about fashion retailing sector: UK versus Spain
2012
Within the international context, fashion retailers have suffered the most in the economic downturn in the last years. Nevertheless, the historically high-margin fashion sectors composite net profit margin was still the highest of all the product groups. Based on the importance of fashion retail sector for the international economy in general, this paper examines the international retailing situation showing sales data between most important retailers around the world in general and Europe in particular. Specifically, this paper offers an overview on fashion retailing sector in the international context in order to study the position of this sector in the international crisis context. Due t…
Distopía, eutopía y crisis social en el cine mainstream (Los casos de Los juegos del hambre y Del revés)
2018
espanolEn el marco de un mundo globalizado, la aparente "desideologizacion" que acompana a los bienes culturales actuales, sirve a los propositos de reproduccion del sistema capitalista, entendido este dentro de su vertiente cultural actual como un sistema omnipresente y omniabarcante. En este sentido, los productos culturales del mainstream estadounidense, continuan constituyendo, aun a dia de hoy, uno de los principales pilares a traves de los cuales el sistema se representa a si mismo, proponiendo y defendiendo determinados modos de vida, en concreto, el American Way of Life. En el actual contexto, el mainstream cinematografico, a traves de productos como “Los Juegos del Hambre” (The Hun…
The role of information technology in relationships between travel agencies and their suppliers
2010
PurposeIn the context of relationship marketing, it is highly important for providers to identify the main buyer relational benefits influencing satisfaction and loyalty so that a continuous and satisfactory business relationship is guaranteed. Since it has been reported that information technology (IT) might constitute a source of satisfaction or dissatisfaction, this paper aims to test the moderating role of IT in the relationships between perceived benefits, satisfaction and loyalty in a business‐to‐business (B2B) setting.Design/methodology/approachA structural equations model was empirically tested. Additionally, the moderating role of IT in the relationships between perceived relationa…
Heat Shock Proteins in Renal Cell Carcinomas
2005
Renal cell carcinoma (RCC) represents one of the most common cancer types in the Western World. One third of the RCC patients had metastasis at presentation with a poor 5-year survival. Nephrectomy is the most important treatment modality of this disease, since most of the RCCs are resistant to cytotoxic chemotherapy and radiation therapy. Recent immunotherapeutic approaches have been shown to improve the survival rate of RCC patients. Thus, RCC appears to have an immunogenic basis, and therefore represents an attractive target for immunotherapies. So far, only a few RCC-associated antigens have been characterized. However, with the implementation of ome-based technologies, an increasing nu…
Heparin versus 0.9% sodium chloride intermittent flushing for prevention of occlusion in central venous catheters in adults
2014
Background Heparin intermittent flushing is a standard practice in the maintenance of patency in central venous catheters. However, we could find no systematic review examining its effectiveness and safety. Objectives To assess the effectiveness of intermittent flushing with heparin versus 0.9% sodium chloride (normal saline) solution in adults with central venous catheters in terms of prevention of occlusion and overall benefits versus harms. Search methods The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched December 2013) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 11). Searches were …
Soil interpretation in the context of anthropedogenic transformations and pedotechniques application
2018
Abstract Following a long and vigorous study carried out by the International Committee on Anthropogenic Soils (ICOMANTH), the Soil Taxonomy (ST) classification system recently incorporated a number of changes to include Human-Altered and Human-Transported soils, generally called anthropogenic soils. These changes underwent careful scrutiny as they affect the current classification of existing soil series, and as the proposals and logics are as yet untested against existing data and descriptions. Particular attention was given to the diagnostic characteristics of the anthropogenic soils and to the Subgroups for Human-Altered and Human-Transported soils. In this study, we consider a frequent…
Reuse of electric vehicle batteries in buildings: An integrated load match analysis and life cycle assessment approach
2019
Abstract The increasing use of renewable energy technologies for electricity generation in buildings will require a growing number of battery energy storage systems (BESS) to enhance the reliability of electricity supply. The increasing number of retired electric vehicle (EV) batteries, expected from the automotive sector, can match this demand as EV batteries can be used as BESS, considering that they have about 80% of their original energy capacity. In this context, the study aims at examining the system, consisting of a BESS made by retired Li-ion EV batteries, a photovoltaic plant (20 kW) and the electricity grid, that provides the electricity required by an existing nearly net zero res…
Sulfites and the Wine Metabolome
2017
International audience; In a context of societal concern about food preservation, the reduction of sulfite input plays a major role in the wine industry. To improve the understanding of the chemistry involved in the SO2 protection, a series of bottle aged Chardonnay wines made from the same must, but with different concentrations of SO2 added at pressing were analyzed by ultrahigh resolution mass spectrometry (FT-ICR-MS) and excitation emission matrix fluorescence (EEMF).Metabolic fingerprints from FT-ICR-MS data could discriminate wines according to the added concentration to the must but they also revealed chemistry-related differences according to the type of stopper, providing a wine me…
