Le suivi lépidoptérologique de la méthode 9c des mesures agro-environnementales a été initié en 2006 par un premier inventaire sur huit bandes fleuries1 (semis au printemps 2005). Par la suite, en 2007, 28 autres bandes fleuries (semis au printemps 2006) réparties sur les régions agricoles Famenne et Condroz ont été visitées2. En 2009, 53 bandes fleuries ont été suivies. 34 des 36 bandes situées au sud du sillon Sambre-et-Meuse (SSSM), qui avaient fait l’objet du suivi précédent, ont été revisitées à trois reprises. En complément de celles-ci, 19 nouvelles bandes (également implantée en 2006) ont été visitées pour la première fois au nord du sillon Sambre-et-Meuse (NSSM). Fort des expériences précitées, 2010 est considérée comme l’année de référence pour la standardisation de la méthodologie du suivi des lépidoptères. Dorénavant celui-ci comportera deux axes principaux : la continuation du suivi sur 20 bandes implantées en 2006 et le début d’un suivi de 20 bandes implantées en 2009. Ces suivis seront menés pendant cinq années à raison de quatre visites de terrain par an. 2011 est donc l’année « deux » du suivi lépidoptérologique utilisant le protocole standardisé l’année précédente.

Although an extensive literature is available concerning the design of travel surveys, fewer research initiatives have been carried out to determine the content of the survey itself. The objective of the present work is to identify such minimum set through a survey (MTSQ – Mini-Travel Survey Questionnaire) targeted to experts in this field. Moreover, it is investigated whether unanimity exists in the experts’ opinions concerning the importance of various types of questions and whether regional and/or professional differences exist. The MTSQ survey was successfully completed by 81 respondents in October-November 2012, mainly from Europe and North America. The study identified the most important questions, which should form the core of any NHTS. This list is especially useful for countries which do not yet have implemented a NHTS, and for defining the set of questions in case a harmonized household travel survey spanning across different countries will be initialized. Secondly, the paper investigated whether unanimity exists in the experts’ opinions. Our analyses clearly pinpointed different evaluations according to the experts’ characteristics, thus it could be concluded that unanimity is certainly not complete. Thus, whenever developing standards for travel surveys these differences should be taken into account, according to both the prospective data users the intended data usages. Especially the differences with respect to the regional context (North-American versus European), and involvement with the NHTS should be acknowledged. [less ▲]

INTRODUCTION: Model-based methods can be used to characterise patient-specific condition and response to mechanical ventilation (MV) during treatment for acute respiratory distress syndrome (ARDS). Conventional metrics of respiratory mechanics are based on inspiration only, neglecting data from the expiration cycle. However, it is hypothesised that expiratory data can be used to determine an alternative metric, offering another means to track patient condition and guide positive end expiratory pressure (PEEP) selection. METHODS: Three fully sedated, oleic acid induced ARDS piglets underwent three experimental phases. Phase 1 was a healthy state recruitment manoeuvre. Phase 2 was a progression from a healthy state to an oleic acid induced ARDS state. Phase 3 was an ARDS state recruitment manoeuvre. The expiratory time-constant model parameter was determined for every breathing cycle for each subject. Trends were compared to estimates of lung elastance determined by means of an end-inspiratory pause method and an integral-based method. All experimental procedures, protocols and the use of data in this study were reviewed and approved by the Ethics Committee of the University of Liege Medical Faculty. RESULTS: The overall median absolute percentage fitting error for the expiratory time-constant model across all three phases was less than 10 %; for each subject, indicating the capability of the model to capture the mechanics of breathing during expiration. Provided the respiratory resistance was constant, the model was able to adequately identify trends and fundamental changes in respiratory mechanics. CONCLUSION: Overall, this is a proof of concept study that shows the potential of continuous monitoring of respiratory mechanics in clinical practice. Respiratory system mechanics vary with disease state development and in response to MV settings. Therefore, titrating PEEP to minimal elastance theoretically results in optimal PEEP selection. Trends matched clinical expectation demonstrating robustness and potential for guiding MV therapy. However, further research is required to confirm the use of such real-time methods in actual ARDS patients, both sedated and spontaneously breathing. [less ▲]

This research aims to explain and understand the organisational diversity observed in the field of Fair Trade Social Enterprises or Fair Trade Organisations (FTOs). The transversal hypothesis is that such a diversity in organisational forms may be linked to the multidimensional (economic, social and/or political) nature of Fair Trade. First, since there are virtually no typologies focused on FTOs, it is necessary to look at how organisational diversity in FT can be categorised. A typology with five categories of organisational forms is suggested. Secondly, this work explores the reasons behind organisational diversity, using both an external, explanatory perspective, and an internal, interactionist perspective. A third key issue is to explore whether FTOs experience tensions between the different dimensions of FT, and how these tensions are managed in the different types of FTOs. These issues are examined under the light of different theoretical approaches linked to “new institutionalism” (economic, sociological and entrepreneurial) and resource dependence theory. The empirical material is provided by interviews with the leaders of 57 FTOs in four European regions: Belgium, France (Rhône-Alpes), the United Kingdom (England) and Italy (Rome). Eight of these FTOs, reflecting the different categories of organisational forms, are analysed more in depth. [less ▲]

Using a unique database of 990 VC-backed Belgian firms, we study whether compatibility between corporate and environmental characteristics matters. We address two questions: (i) Does the interplay of company, industry, and product factors affect the expected returns of the VC-backed firms? (ii) Does the joint compatibility between these factors results in a non-linear increase in performance? Panel data analysis shows a significant influence of factor compatibility on returns. Quantile regression analysis indicates a non-linear relationship between the return and its determinants. Conjoint analysis identifies certain combinations of factors, which collapse into classifiable patterns described in the strategic management literature. [less ▲]

Furthermore, plausible explanations are forwarded regarding the resemblances between Spain’s and Poland’s policies towards neighbourhood: the national interests considerations based on the constructivist approach; policy entrepreneurship in the context of institutional conditions of the European Foreign Policy and the process of lessons drawing in the framework of the European Foreign Policy policy-making process.

In the continuity of stakeholder theory, much of the current literature on (corporate) governance and business ethics looks at how organizations involve their stakeholders at different decision-making levels (Carroll 2004; Clarkson 1995; de Graaf & Herkströter 2007; Freeman & Reed 1983). According to Freeman (1984), stakeholders are ‘any group or individual who can affect or is affected by the achievement of an organization's purpose’ (148); typically: the owners, the managers, the workers, the volunteers, the financing bodies, the partners, the suppliers, the customers/beneficiaries, etc. A continuum of involvement can be highlighted, from the rather passive strategies (stakeholder information) to the more active ones (stakeholder representation). Among the latter, involvement or ‘cooptation’ of stakeholders in the governance structures such as the general assembly and the board of directors is increasingly presented as a strategy mirroring a long-term relationship between the organization and a particular stakeholder category (Mitchell et al. 1997). Traditionally, the owners are the category of stakeholders that is co-opted in the governance structures. Indeed, the power of decision is part of the property rights (Milgrom & Roberts 1992). It allows owners to ensure that the enterprise is run according to their own objectives. Thus, in for-profit enterprises, the investors are the owners and, as such, they have the right to decide. They exercise this right by their presence at the general assembly. But not all enterprises are investors-owned firms. In some enterprises, ownership is in the hand of other stakeholders, like in producer, consumer or worker cooperatives. Others, like nonprofit organizations, can even be seen as firms without owners (Hansmann 1996). This chapter raises the question of stakeholder involvement in social enterprises, which are ‘non-investor owned’ and can broadly be defined here as organizations pursuing social aims through their economic activity (Defourny 2001; Defourny & Nyssens 2006). In these organizations, the configuration of stakeholder involvement contrasts with that of for-profit businesses in at least two ways. First, social enterprises are more likely than other types of organizations to be set up through a process of collective entrepreneurship which often involves a diversity of actors who each have a ‘stake’ in the pursuit of one or several organizational missions (Defourny & Nyssens 2006; Haugh 2007; Petrella 2003). Second, social enterprises seem to have a stronger tendency to give a voice to the actors with whom they interact –i.e., to involve their beneficiaries, supporters, funders or partners within their governance structures (Campi et al. 2006; Huybrechts 2010; Münkner 2004; Rijpens 2010). They usually use legal forms that allow and encourage economic democracy by recognizing stakeholders other than investors the right to participate formally in the governance bodies. While, as suggested by Campi et al. (2006; 2012), the presence of multiple stakeholders observed in a number of social enterprises may be linked with the diverse goals pursued by these organizations, such presence –or absence– may be due to many factors which have no direct links with organizational goals. As suggested in this chapter, the organizational need for resources (in a broad sense) and the drive to conform to external expectations may be two key factors. In any case, the diversified patterns of stakeholder involvement in social enterprises confirm the need for a more comprehensive account of stakeholder involvement in these organizations. Although several attempts have been made to theorize stakeholder involvement in social enterprise governance, it is still a much under-researched topic. We believe that this research gap is due not only to the infancy stage in which social enterprise research is located, but also to a lack of connection and integration of this research within the broader study of organizations. Indeed, while new theoretical developments centered on the specific features of social enterprise are needed, these developments cannot be made independently from the knowledge built for more than a century regarding how organizations are structured and operate. This chapter aims to examine stakeholder involvement in social enterprise governance using two types of theoretical lenses each embodying a rich research tradition in organization theory. The first lens refers to strategy and examines organizations (in this case governance structures) in terms of their dependency on a set of resources. The second lens uses legitimacy arguments to explain organizational governance as a social construct located in a broader setting of social relationships. The first two sections will present each of these views and examine their contributions to understanding stakeholder involvement in the governance structures of social enterprises. Then, a comparative case study on work integration social enterprises will serve to illustrate how both research avenues can be combined so as to better grasp social enterprise governance as a complex and multi-dimensional practice.

Direct searches for lepton flavor violating Higgs boson decays in the τ μ channel have been recently reported by the CMS collaboration. The results display a slight excess of signal events with a significance of 2.5σ, which translates into a branching ratio of about 1%. By interpreting these findings as a hint for beyond the standard model physics, we show that the Type-III 2HDM is capable of reproducing such signal while at the same time satisfying vacuum stability, perturbativity, electroweak precision data, measured Higgs standard decay modes and low-energy lepton flavor violating constraints. We have found that the allowed signal strength ranges for the bb, WW* and ZZ* standard channels shrink as soon as BR(h→τμ)∼ 1% is enforced. Thus, we point out that if the excess persists, improved measurements of these channels may be used to test our Type-III 2HDM scenario. [less ▲]
