The stage of the oestrus cycle at which the GPG protocol is instigated affects the results obtained and justifies presynchronisation treatments to increase the number of animals that are within the 5(th) and 12(th) day of the cycle, which is the optimal period of treatment. Increased fertility, especially in multipara animals was observed. An inverse relation between fertility and the diameter of the follicle present at the time of prostaglandin administration or second injection of GnRH was described. However, it seems that the type of gonadorelin used, the dose or the timing of injection in relation with the PgF(2alpha), does not affect fertility The effect of the timing of insemination in relation to the second injection of GnRH is significant. This interval influences the rate of fertility and embryonic or foetal death and the sex-ratio. [less ▲]

The aim of this paper is to identify reasons why workers would resign from their jobs early and to what extent the reasons for retirement are really encountered. A number of non satisfaction factors either personal or job-related were considered in an age comparison dimension. A questionnaire has been elaborated for the purpose of this study and includes items related to job intention to quit and (potential vs encountered) non satisfaction factors. These factors consider both personal leaving factors and job related leaving factors. The latter include three theoretical sub-dimensions: working conditions, organizational and structural changes and job recognition. Exploratory factor analysis of the 58 items produced eight usable leaving factors: (1) lack of resources and autonomy; (2) work pressure; (3) lack of personal development; (4) job insecurity; (5) personal reasons; (6) organizational changes; (7) a hostile work environment and (8) a poor image of the company. The sample includes 1772 workers from 11 Belgian companies. The response rate is 50.23 per cent. All sectors of activity are included in the survey. We consider five categories of age (under 25 years old, between 25 and 35, between 36 and 45, between 45 and 55, and over 55 years). As far as the results are concerned, first of all, organizational changes encountered by a large majority of workers appear to be an important leaving factor, especially for older workers. Second the lack of personal development, though experienced by the oldest workers in a larger extent, is the main reason for leaving in all age groups. Third personal factors are also important for the younger and the oldest workers. Moreover work pressure is a phenomenon encountered by all workers, particularly the youngest, but it is less of a reason for leaving. Another result is that job insecurity factor is experienced by youngest workers. Finally, the differences between the young and the not so young are not very clear-cut, supporting the idea of the age management perspective. [less ▲]

Several studies on the sources of funding for local NGOs in Africa highlight their dependence on foreign donors, while in developed countries, these organizations have multiple resources. Investigations previously done show that the majority of resources of local NGOs come from foreign donors, and most of them are dead at inception due to lack of funding. Before reaching the beneficiaries, financing goes through several players who are related by an explicit contract: Foreign donors - International NGOs - Local NGOs - Endogenous groups - beneficiaries populations. The literature points to the existence of a contractual relationship between the one who runs the activities and the one that funds them. Yet despite this explicit contract, some actors in this chain of relationships are influenced by other factors and / or their interests and make decisions that have no direct links with the mission of the organization. This leads us to ask ourselves two questions: first, the question about the factors that characterize the relationship between actors and secondly whether at all levels, the actors involve other stakeholders. The present paper aims to provide a conceptual and theoretical framework to characterize the agency chain relationship between these different actors. Although there are studies on the application of the agency theory in the governance of Nonprofit organizations, there have been very few studies done on the agency chain relationship between these organizations. It is then necessary to make new theoretical developments on how local NGOs in Africa in general, and Burundi in particular, are funded and governed; and that, in the case where the actors in the chain relationship are in different contexts. To do this, we will first mobilize and apply the agence theory and others theories of governance at this agency chain relationship. We conclude by showing the peculiarity of Africa in general, and Burundi in particular with additional elements that enhance this agency relationship, making then the conceptual model complex.

La mammite est une pathologie aux conséquenceséconomiques redoutables dont le contrôle est difficile. Une étude réalisée par OSaM (l’observatoire de la santémammaire) dans 350 fermes a permis de quantifier de la situation sanitaire mammaire, de mieux cerner les pratiques d’élevage les plus propices à une bonne maîtrise des infections mammaires et de proposer des recommandations de nature plus préventives. Ce premier article propose une synthèse des conclusions tirées en matière de diagnostic et de traitement. [less ▲]

This paper presents a reflection about the key success factors involved in the process of turning traditional courses into on-line active courses. Within the context of ‘FORMADIS’ and other programmes, more than twenty projects have been accompanied by the LabSET in the past 3 years. The paper gives an overview of the tools and methods used for teacher support and training. It examines the projects ‘doing well’ and analyse what makes them sucessful. It considers the moment at which the success factors take place (before, during and after the various phases of development). It illustrates these key factors with practical examples. Whereas the majority of these factors seem to be obvious, this analysis will help considering the relations between them as well as the way of managing them successfully. [less ▲]

The goal of this study was to determine which environmental factors affect the spatial variability of annual minimum streamflow characteristics for 34 rivers in Wallonia (Belgium) using two complementary methods: theascending hierarchical classification method and the linear correlation method. Both methods were applied after principal component analysis transformation was applied to the data. The ascending hierarchical classification method (Ward’s method) identified the effect of lithology and anthropogenic activity (groundwater pumping) on the fundamental characteristics of annual minimum flows. Rivers that drain a relatively permeable substrate are characterized by very high flow volumes with low interannual variability, high interannual variability of the period of occurrence, and small asymmetry coefficients. Rivers that drain low permeability or impermeable substrates show the opposite patterns. Rivers in which flow is subjected to artificial influences are characterized by greater variability of the magnitude and of the period of occurrence of annual minimum flows than natural rivers. Analysis of linear correlations between streamflow characteristics and environmental factors highlighted a correlation between the form of the distribution curves of annual minimum flows and several environmental factors (climate, land use, location and physiographic characteristics of the watersheds).

An initial database containing growth records of 101,000 lambs obtained within the context of the national meat sheep improvement program was used to quantify reproductive and productivity (total litter weight) traits of ewes of the Noire de Thibar breed, and to determine the influence of non-genetic factors on these traits. A database was then generated: it comprised 64,137 lambings over a 12-year period (1991-2002), and 25 farms and 48 flocks. The mean fertility rate in the flocks was 80.1±12.9% with highly significant effects (p<0.001) of the farm and lambing year. At birth, the average litter size per lambing ewe was 1.32±0.47. It dropped to 1.23±0.55 at 70 days after lambing. All main sources of variation (farm, lambing year, lambing month, and dam age) retained in the model as well as their interactions significantly affected the litter size at different stages after lambing. Survival of all the lambs in the litters between birth and 70 days post-lambing was observed in 89.9% of the ewes. Entire loss of the litter was observed in only 5.8% of the ewes. An analysis of variance revealed that factors such as the lambing year, lambing month, dam age, sex of the litter, and litter size at birth had a highly significant effect on the proportions of ewes with different levels of lambs' survival within litters. On average, the productivity of the Noire de Thibar was 6.6±2.2, 10.3±3.5 and 18.6±6.6 kg at 10, 30 and 70 days after lambing, respectively. The main factors of variation (farm, lambing year, lambing month, dam age, litter size), and some second-level interactions had highly significant effects (p<0.001) on the studied productivity traits. Ewes aged four years and which had male triplets yielded the highest productivities at 70 days after lambing. This preliminary work on the reproductive and productivity traits of Noire de Thibar ewes is essential to develop a ewe selection index as part of a genetic improvement scheme for this breed.
