Intermodal freight transport is the movement of goods in one and the same load unit or vehicle by successive modes of transport without handling of the goods themselves when changing modes (European Conference of Ministers of Transport et al. 1997). Altough it has still a small market share compared to road transport, it becomes more and more apparant that intermodal transport transport will play an important role in the future. Intermodal transport is more environmental friendly than road transport (Kreutzberger et al., 2003) and has a positive effect on the congestion problems (Van Schijndel and Dinwoodie, 2000). A third and important positive feature of intermodal transport is that it can easily fit in the supply chain management efforts by the companies. In this paper the missing links and opportunities for the intermodal transportsector are analysed. Also solutions for overcoming these bottlenecks are proposed. [less ▲]

During the last twenty years, we observed a constant reduction of mineral fertilizer use, due to prices increase and environmental awareness, and an increase of crop removal, leading to a phosphorus (P) budget decrease. These changes are feared for a decrease of soil P content, which is already observed in some regions in Wallonia. However, P being an essential element for plant growth, is a such management compatible with yield maintaining? Are the current cropping systems sustainable? To answer to the questions, different studies are made. However, long-term data are rarely available to understand the influence of cropping systems on the soil behavior, leaching risks or to choose adequate indicators of P. To answer to these questions in our soils, 2 experimental plots of the Walloon Agricultural Research Center. These experimental plots were established in 1967 and 1959 in order to evaluate the effect of, respectively, 3 P and K input levels and different organic inputs on the production. Soils samples were taken in plots and analyzed in laboratory. So, different P indicators and edaphic parameters were determined. This study showed that all indicators are coherent with P levels and correlated with yields but no many differences can be shown between fertilizer types. Meanly, zero P-input engenders a decrease of yield of 7%, while a double input increases yield of 2% in comparison to plots with an input corresponding to crop export. So, financially, the zero P-input option is rarely profitable in the long-term and double input of P removed is never financially sustainable. Leaching into deeper soils levels was studied with analysis of deeper horizons which indicated any leaching , even in plots with double inputs. Indeed, soil P contents in depth were similar in these plots than those with no P-inputs or soils under forest cover. So, to conclude, these plots help to study the sustainability of cropping systems in real situations and to determine appropriate management of P. [less ▲]

How can new players seeking to serve nonstandard worker categories (such as project-based workers) establish themselves into labour markets that are highly institutionalized? This paper explores the case of SMart, a Belgian community-based labour market intermediary that successfully developed solutions to better represent the interests of project-based workers and secure their discontinuous careers. Using an organizational legitimacy approach, we find that labour market entry and growth involve different types of boundary-crossing when addressing the needs of workers that do not fit into established categories. However, to justify boundary-crossing, the new player must complement its pragmatic work on delivering new services and tools with conceptual (cognitive) and structural (moral) legitimation work.

A sustainable agricultural production chain (“from stable to table”) is not produced ex nihilo, especially when its future hinges on demand from a supermarket distribution circuit. Many of the standards of conventional production chains effectively serve as references for intermediaries and consumers alike. The tensions between sustainability standards and market standards are thus the crucial areas in which negotiations about the chain’s future take place. These inextricably intertwined technical, social, and economic tensions are the subject of this research. These tensions create a situation of uncertainty, that is to say, of choices between pathways. They are both a springboard for action and the cause of inaction, depending on how they are interpreted. This exploration is what justified an intervention-research approach that combines restating questions and changing relations to explore the possible pathways to take [less ▲]

The quantification of seed dispersal and predation processes has been gaining increased importance in the assessment of forest responses to anthropogenic disturbance, but also in developing an understanding of forest dynamics facing particular reproductive strategies. Seed removal rate is a reliable estimator of animal activities relating to these processes and can be quickly and easily estimated using a rapid assessment method (RAM) described by Lermyte & Forget (2009) and Boissier et al. (2014). This method consists in selecting trees reaching a given fruit crop in plots of interest and estimating, under each tree, the proportion of removed seeds in a single quadrat among the places having the highest crops; the proportion of removed seeds is obtained by enumeration of fruit scraps and intact fruits and estimation of their seed contents. The objective of this work is to evaluate the reliability of this method and to propose alternative estimation protocols (APs) in order to obtain an index of animal interaction with seeds. To do so, we estimated produced and removed seed numbers in up to 30 random 1 sq.m. quadrats under a total of 19 trees of Afzelia bipindensis, Dialium pachyphyllum/zenkeri and Xylopia staudtii. Secondly, we investigated the influence of tree size and fruit production on seed removal rate using a generalized linear mixed model. Thirdly, we used a generalized linear mixed model and a bootstrap procedure to test if RAM and APs are biased. Then, we compared their accuracy throughout their mean squared error, also obtained with a bootstrap approach. Despite its interesting accuracy, we showed that the RAM is positively biased. Removal rate was obviously influenced by canopy size and fruit production whereas the quadrats with higher fruit production have higher seed removal rates. Thus, trees with representative sizes and crops of the studied plots have to be sampled. Secondly, as an AP, random selection of several quadrats was found to be the best method. Based on these results, we recommend using the mean of three random quadrats per tree to estimate seed removal rate. It is an unbiased estimator, more accurate and more time efficient than the RAM. However, attention should be paid to select a proper quadrat size, in line with seed and fruit numbers, since the accuracy of the methods depends on these quantities. Such a choice could be made using a mean squared error criterion obtained from a preliminary intensive sampling of some specimens of the focal species. [less ▲]
