The primary objective of this paper is to explore the influence of socio-demographic and contextual variables on the multimodal character of public transit journeys. Accounting for multimodality in public transit journeys is important from a demand modeling point of view, especially in the assessment of new projected public transit infrastructure. To meet the objective, data from the national household travel survey of Flanders (Belgium) is analyzed. Based on 2,202 public transit journeys, the main public transit mode choice (bus/tram/metro or train) and access/egress mode choice are simultaneously estimated using a multinomial logit model, and by explicitly making a distinction between unimodal and multimodal transit journeys. The results indicate that various socio-demographical (e.g. age, gender, level of education, household income) and contextual factors (e.g. journey distance, journey motive, urbanization degree, car availability) significantly influence the joint decision process. Total journey distance and car availability are identified as the most important explanatory variables. In terms of model performance, the model appears to yield satisfactory predictions, justifying the integration of the model in more general demand modeling frameworks. [less ▲]

In this work, the error made by frequency domain homogenization of windings in 2-D magnetodynamics is quantified. To that end, the homogenized fields are combined with the analytical solutions (a) of eddy currents flowing in a circular conductor placed in a uniform alternating magnetic induction (proximity effect) and (b) of current density in conductors with non-zero net current (skin effect). They are then compared to the fields from the fine model, taken as reference. It is shown that error on resistance can reach 10\% at high frequencies for magnetic components with a limited number of turns. Procedures to improve winding R, L parameters estimation from homogenized solution are introduced. [less ▲]

The mere exposure effect is usually considered a robust phenomenon whereby people’s attitudes can easily be influenced. However, recent studies suggest that some conditions must be met for this effect to emerge. In this experiment, the influence of the features of a specific material on the mere exposure effect was examined in an ecological context. Children were told that they would play a game during which they would have to buy several items in different shops. In these shops, half of the participants were incidentally exposed to two target stimuli. During a subsequent judgment phase, the target stimuli were presented to each child, either with perceptually similar items or with perceptually dissimilar items. Prior encounter with an item only influenced children’s preference choices when the test items were dissimilar. These findings are discussed in terms of the processing styles that are necessary for the mere exposure effect to appear. [less ▲]

The recent technological developments are boosting the opportunities of accurate method to monitor resource use efficiency in agriculture and in their wake, precision livestock farming (PLF) has experienced huge developments over the past decade. These developments focus on the optimization of individual performances of farm animals as opposed to herd management. The aim of this paper is to explore a method to detect accurately and to analyze changes in cattle's behaviors on pasture during grazing time using signals from the inertial measurement unit (IMU) of mobile devices as a possible tool to manage individual grazing behavior. Commercial iPhones or iPods, which include a 3-axis accelerometer, a gyroscope and a GPS sensor, are fitted on a halter and placed on the neck of grazing cows. The acquired IMU data are recovered using an open source application (Sensor Data, Wavefrontlabs) and analyzed in a “white-box” model of the cows’ movements. First results using time-domain analysis allowed the detection of grazing behaviors showed accuracies ranging between 84% and 96%, attesting the relevancy of the method. Refined signal processing method will improve the detection but will also inform more about the relative link between the behaviors and the pasture attributes such as sward height, composition and nutritive value.

For conservation biology and sustainable management, the natural character of tropical forest is a crucial issue. Its assessment is usually based on ecological proxies such as forest composition and structure. However the estimation made on this basis only considers short term processes at a local scale. In contrast the long term processes are appraised by palaeoecological proxies (such as pollen) at a regional scale. So as to assess the degree of naturalness of tropical ecosystems in a conservation perspective it is important to combine a long temporal scale as well as a fine resolution spatial scale. Such approaches using palaeoecological proxies have been recently tested in temperate Europe but little in tropical ecosystems. Nonetheless the long term preservation of the palaeoecological material and its broad presence in the environment are necessary conditions to fulfill. In this perspective soil charcoal appears to meet these requirements. In this paper we aimed at assessing the naturalness of tropical forest using soil charcoal from southeastern Cameroon. Fieldwork involving as well archaeology as botany was undertaken at 53 sites. We quantified charcoal in soil samples by layers of 10 cm taken from pits located in the center of plots of botanical inventory. Spatial projections were performed using statistics together with multivariate analyses. Radiocarbon dating allowed interpreting the temporal framework. Results showed the ubiquitous presence of charcoal at each site. Main charcoal peaks were interpreted as fields (slash-and-burn agriculture) in the vicinity of ancient villages. These practices shaped the forest over time which cannot be considered as natural anymore. This underlines the potential input of the use of palaeoecological material in conservation biology and sustainable management issues. Charcoal fragments are under taxonomical identification and may provide new insights on the long term history of forest composition. [less ▲]

A general formalism for the evaluation of time-reversal odd parton distributions is applied here to calculate the Boer-Mulders function. The same formalism when applied to evaluate the Sivers function led to results which fulfill the Burkardt sum rule quite well. The calculation here has been performed for two different models of proton structure: a constituent quark model and the MIT bag model. In the latter case, important differences are found with respect to a previous evaluation in the same framework, a feature already encountered in the calculation of the Sivers function. The results obtained are consistent with the present wisdom, i.e., the contributions for the u and d flavors turn out to have the same sign, following the pattern suggested analyzing the model-independent features of the impact parameter dependent generalized parton distributions. It is therefore confirmed that the present approach is suitable for the analysis of time-reversal odd distribution functions. A critical comparison between the outcomes of the two models, as well as between the results of the calculations for the Sivers and Boer-Mulders functions, is also carried out. © 2009 The American Physical Society.

Nowadays, analysis of bibliographic databases is a current practice, especially the comparison between traditional, commercial databases and search engines as Google Scholar that has wind right aft. A great deal of researchers analyzed the contents or the citations system of various databases. Some compared the contents of several databases, for specific scientific domains, searching by author (Mikki, 2010; Cecchino, 2010) or keywords (Falagas, 2008). There are no studies concerning the precise domain of geography. This study covers bibliographical databases specialized in geography (physical and human) and Google Scholar search engine. This analyze will point out to geographers what a research in Google Scholar search engine can offer, regarding exclusively contents, in comparison with traditional databases: WOS, Francis and Georef. This analysis does not aim to underline the difference of databases features, but to show what a research in certain databases can bring, from the point of view of contents. To perform this study, we use keywords (in English) and establish them for the physical and human geography according to actual subjects of the respective fields. The research will bring new concrete results given that no comparison of this type was led between the traditional databases used by geographers and Google Scholar. We also hope to give an idea of the possible evolution of the contents for Google Scholar search engine during the determined period of our study. [less ▲]

We consider power systems for which the amount of power produced by their individual power plants is small with respect to the total generation of the system, and analyze how the transient instability mechanisms of these systems change qualitatively when their size or the dispersion of their generators increases. Simulation results show that loss of synchronism will propagate more slowly and even stop propagating. Given the evolution of power systems towards more dispersed generation and geographically larger interconnections, we conclude that research in transient stability should focus more on the propagation of the loss of synchronism over longer time periods, so as to assess what happens to the overall system subsequently to the loss of synchronism of the first generators. We also argue that such studies might be very useful in order to provide guidelines for setting up power system control schemes to contain the propagation of instabilities, and we discuss some ideas for designing islanding based emergency control schemes for this.

Le volume aborde l'anaphore sans se lier à une théorie déjà fixée : il est conçu dans une perspective contrastive qui vise seulement à préparer une synthèse typologique. Il s'attache à des langues diverses (anglais, français contemporain et médiéval, grec ancien, vieil-irlandais, italien, latin), dans une perspective globalement synchronique, sans pour autant exclure les phénomènes de grammaticalisation. Y sont étudiés des genres textuels variés, littéraires, oraux, voire émis par des locuteurs atteints de troubles du langage. Les approches sont elles aussi multiples (fonctionnement, notamment sémantique, de tel grammème ; calcul de la référence ; emplois discursifs, littéraires ou plus spontanés). L’ouvrage propose un parcours des échelles qui permettent l’étude de l’anaphore. [less ▲]

We studied the effects of short-term submaximal exercise on the plasma levels of myeloperoxidase ([MPO]) and C5a anaphylatoxin ([C5a]), taken as specific markers of polymorphonuclear neutrophil (PMN) and complement activation, respectively. Eleven young, healthy male volunteers were subjected to a constant-load concentric exercise on a cycle ergometer (20 min at 80% maximal oxygen uptake). Mean resting MPO and C5a concentrations were 437 +/- 113 and 0.47 +/- 0.21 ng/ml, respectively. During exercise, [MPO] and [C5a] increased significantly (p < 0.001) towards respective peak values of 649 +/- 131 and 1.3 +/- 0.6 ng/ml. A rapid decrease of both [MPO] and [C5a] was observed during recovery. The similar time course of [MPO] and [C5a] changes and the highly significant relationship between these two variables (r = 0.651; p < 0.001) argues for the possible involvement of the complement anaphylatoxin C5a in the process of PMN degranulation. During exercise, the number of circulating PMN increased (+80%; p < 0.001) and remained practically unchanged up to 20 minutes of recovery. As [MPO] and PMN count were not significantly related (r = 0.2; p < 0.1), we concluded that the activation of PMN was independent of their mobilization. [less ▲]

OVERVIEW: Anaplasma species, Ehrlichia species and Rickettsia species are vector-borne pathogens infecting a wide variety of mammals, but causing disease in very few of them. Infection in cats: Anaplasma phagocytophilum is the most important feline pathogen among these rickettsial organisms, and coinfections are possible. Little information is available on the pathogenesis of these agents in cats. Clinical signs are usually reported soon after tick infestation. They are mostly non-specific, consisting of fever, anorexia and lethargy. Joint pain may occur. Infection in humans: Some rickettsial species ( A phagocytophilum, Ehrlichia chaffeensis, Ehrlichia ewingii, Rickettsia conorii, Rickettsia rickettsii, Rickettsia felis, Rickettsia typhi and Candidatus Neoehrlichia mikurensis) are of zoonotic concern. Direct contact with cat saliva should be avoided because of potential contamination by R felis. Infected cats are 'sentinels' of the presence of rickettsial pathogens in ticks and fleas in a given geographical area, and they signal a risk for people exposed to vectors. [less ▲]
