Distributors are faced with loading constraints in their route planning. These loading constraints include multi-dimensional packing constraints, unloading sequence constraints, stability constraints and axle weight limits. Not taking into account these loading constraints would make the planning often not feasible in practice and gives rise to last-minute changes in planning which may result in additional costs. The development of vehicle routing models that incorporate loading constraints is vital for a more efficient planning of routes. The number of contributions to this field of research has increased enormously in the last couple of years. Almost sixty percent of the papers that study the integration of loading constraints in routing models are published after 2009. The contribution of this paper is twofold. First, an overview of recent developments in this research field is provided. Literature on all transport modes in which loading constraints play a key role is discussed (trucks, airplanes, ships, and automated guided vehicles). To identify the loading constraints considered in each paper, a state-of-the-art classification scheme on loading problems is used. Second, research gaps and opportunities for future research are identified. [less ▲]

Fast rotation in massive stars is predicted to induce mixing in their interior, but a population of fast-rotating stars with normal nitrogen abundances at their surface has recently been revealed (Hunter et al. 2009; Brott et al. 2011, but see Maeder et al. 2014). However, as the binary fraction of these stars is unknown, no definitive statements about the ability of single-star evolutionary models including rotation to reproduce these observations can be made. Our work combines for the first time a detailed surface abundance analysis with a radial-velocity monitoring for a sample of bright, fast-rotating Galactic OB stars to put strong constraints on stellar evolutionary and interior models.

This article proposes to apply Steen’s (2008) 3D model of metaphor analysis in communication to a corpus of political discourse, in this case citizen discourse. Our corpus has accordingly been analysed by making a distinction between three layers of metaphor, respectively at the linguistic (direct vs. indirect metaphors), conceptual (novel vs. conventional metaphors) and communicative levels (deliberate vs. non-deliberate metaphors). Our results suggest that making the distinction between deliberate and non-deliberate metaphors lead to meaningful political insights, notably pointing to differences in saliency of the source domains in terms of which citizens make sense of Belgian federalism. In this regard, the family domain, and more especially the metaphor BELGIAN FEDERALISM IS A LOVE RELATIONSHIP appears to function as an important conceptual reference point for the citizens’ understanding of the political relations in the Belgian context.

This communication aims at assessing the bias introduced by the use of the Euclidean distance in the context of geographic profiling analyzes. It proceeds by a comparison of road and Euclidean distances of about 1 000 pairs of origin-destination (crime sites – criminal’s anchor point) from the database of the Belgian Federal Police. Comparisons are differentiated by the density of road network (rural and urban areas) and the statistical parameters of the resulting distributions are exploited in the application of the most common geographic profiling model called the distance decay model.

Introduction Integrated management of wireworms (Coleoptera: Elateridae) depends upon approaches applied both above- and belowground, and over several spatial scales. While foraging, these soil pests use biotic and abiotic signals to orientate towards target plant organs. Development of efficient techniques for implementation in integrated strategies relies upon improved knowledge of this process. In particular, an important step consists of elucidating the role of volatile organic compounds (VOC), emitted by belowground plant organs, in wireworm chemical ecology. This would have a positive impact on push-pull strategies and varietal selection developed against these insects. Literature In this work, we summarized the available data regarding wireworm foraging behavior as well as variables that should be considered when studying the potential role of plant-produced volatile semiochemicals. This includes CO2 gradients and other host-related cues, temperature, relative humidity and soil moisture, and wireworm physiological stage. We also review what is known of the sensory apparatus of wireworms, since this is involved in every step of the foraging process. Conclusion Some baseline data for studying VOC related wireworm foraging behavior exists. Using it as a tool in applied entomology should result in discovery of the semiochemicals that underpin trophic interactions involving these pests. However, most of the key pest species are not fully described with regards to the parameters detailed here. Obtaining accurate information to fill the current knowledge gaps will be needed in order to devise new integrated management strategies. [less ▲]

The different steps of the foraging process of wireworms (Coleoptera: Elateridae) would be better understood if accurate and holistic information regarding the role of plant-produced chemicals constituting their environment were available. Volatile organic compounds (VOC) play important roles in the interactions between plants and insects in many ecosystems, whether they take place aboveground or belowground. The roles of VOC are still relatively unknown for wireworms, and deserve attention. Here, we performed three experimentations with barley roots as baits. In the two first, we assessed the effect of chopped roots and fungus infected roots on the orientation of wireworms. In the third experiment, the larvae were confronted to both healthy and fungus infected roots. We discuss the results in terms of suitability of the olfactometers we designed for the investigation of olfaction in wireworms, and we provide suggestions to improve their use. [less ▲]

Age-related changes in intestinal flora and host defences, the receipt of antibiotic treatment, and the presence of underlying diseases are some of the most common risk factors associated with Clostridium difficile infection. Therefore, retirement care facilities for elderly people have been pinpointed as frequent sources of contamination. There is only limited data regarding the presence and epidemiology of C. difficile in nursing homes, and this gap in the current literature emphasises the need to gain a better understanding of the situation in order to prevent the emergence of new outbreaks among this population group.

Cancer is a chronic illness that impacts both patients and family members. Spouses will often take on a caregiver role, meeting psychosocial needs such as health professional needs and information needs. This caregiver role can also create emotional distress. Moreover, spouses might experience perceived inequity characterized by a combination of feelings of overinvestment and of underbenefit. This perception of inequity can also lead to emotional distress. Given the consequences of cancer on spouses, psychological interventions may be one means for helping them to cope. In this study, cognitive and behavioural methods are proposed to spouses in order to support them facing their partner’s cancer and their own issues. The overriding objective of this study is to satisfy the psychosocial needs of cancer patient spouses. In order to reach this objective, it compares the efficacy of two methods of action: 1/ hierarchical organization of psychosocial needs and problem-solving, and 2/ hierarchical organization of psychosocial needs alone. This research also aims to assess the influence of the perception of inequity that spouses might feel on the utilization of the two methods of action. The main hypothesis was that the combination of the two methods of action would have a greater and intensified impact on the assessed dependant variables than the utilization of the hierarchical organization of psychosocial needs alone. Thirty-seven spouses were randomly assigned into two groups: the experimental group (n= 19) and the control group (n= 18). The methodology provided identical protocols to the two groups with one difference in that the training period differed in order to measure the effect of training for problem-solving skills. The average age of participants in the experimental group was 58 (SD = 11) on average, and 57 (SD = 11) in the control group. They were asked to complete several questionnaires at three different time periods with a three-week time interval (T0, T1 and T2) assessing these dependent variables: psychosocial needs and emotional distress (anxiety and depression). Socio-demographic data and the perception of inequity were only evaluated at T0. At T0, all participants realized a hierarchy of psychosocial needs. Between T0 and T1, the experimental group trained in the problem-solving method while control group trained between T1 and T2 for this method. Repeated ANOVA measures were conducted to assess the evolution of the psychosocial needs. Student t-tests were computed to assess the influence of inequity perception on the utilization of the two methods of action. The results confirmed previous findings demonstrating the psychosocial needs in spouses of cancer patients. Indeed, it appears that these participants perceive more psychosocial needs than those of similar samples. This difference might be explained by the period of our intervention which occurred earlier than in experimental designs of similar studies. The overall emotional distress felt by our participants was characterized by anxiety. Therefore, being the caregiver of a cancer patient seems to foster anxiety more than depression. The results confirmed the main hypothesis showing a significant decrease of the number of unsatisfied psychosocial needs when participants have used the two methods of action. This decrease was observed whenever the combination was implemented. In other words, the combination of the two methods of action optimized meeting psychosocial needs. However, the perception of inequity did not seem to influence the utilization of these two methods. This research presents some limitations in the form of a small sample size and of a single assessment of inequity perception at T0. Nevertheless, the results of this preliminary study remain interesting and promising: further research could enhance the employed experimental design in a larger sample in order to obtain more robust results.

Objectives: Our objective is to achieve a phenomenological cross-study of melancholic and manic crises. To do this, we analyze the relationship between these two psychopathological states by means of the concepts of "narrative identity" and "intentionality". Method: From clinical cases and with reference to various theoretical models derived from phenomenological psychopathology, we discuss similarities and differences between mania and melancholia. Results: Narrative identity is based on a double movement: that of the enunciation of a speech focused on his history and that of an act of creation. From different clinical situations, we find that: (1) the melancholic retains the ability to elaborate a narrative about his history but the creative dimension of this narrative is absent, and (2) conversely, the manic experiences only the creative dimension. Discussion: Intentionality, as the tendency of consciousness to move toward something beyond itself, proves to be the center of the manic existence without being able to set itself within the boundaries of factual constraints. The melancholic, conversely, experiences an existence in which consciousness has lost its capacity to aim beyond itself. Conclusions: Melancholia and mania are quite specific forms of being-in-world with particular identity and temporal experiences. These two states share a fundamental psychopathological feature, that we named here “manque chiasmatique”: they are disorders of the intentional movement that constitutes narrative identity, that is, of the dialectics between the rootedness (“enracinenment”) of self in its past and the possibility of creation of a new identity.
