We document a new empirical phenomenon in which the aggregate positions of money managers, who are sophisticated speculators in the commodity futures market, as disclosed by the Disaggregated Commitments of Traders reports, can predict the cross section of commodity producers’ stock returns in the subsequent week. We employ a number of cross-sectional methods, including calendar-time regression analysis, single-sort, double-sort, and Fama–MacBeth regressions, to confirm the predictability results. The results are more pronounced in firms with higher information asymmetry. We thus add more empirical evidence to the literature on costly information processing, which leads to gradual information diffusion across asset markets.

The Welfare Quality® (WQ) protocol for on-farm dairy cattle welfare assessment describes 33 measures and a step-wise method to integrate the outcomes into 12 criteria scores, grouped into four principle scores and into an overall welfare categorisation with four possible levels. The relative contribution of various welfare measures to the integrated scores has been contested. Using a European dataset (491 herds), we investigated: i) variation in sensitivity of integrated outcomes to extremely low and high values of measures, criteria and principles by replacing each actual value with minimum and maximum observed and theoretically possible values; and ii) the reasons for this variation in sensitivity. As intended by the WQ consortium, the sensitivity of integrated scores depends on: i) the observed value of the specific measures/criteria; ii) whether the change was positive/negative; and iii) the relative weight attributed to the measures. Additionally, two unintended factors of considerable influence appear to be side-effects of the complexity of the integration method. Namely: i) the number of measures integrated into criteria and principle scores; and ii) the aggregation method of the measures. Therefore, resource-based measures related to drinkers (which have been criticised with respect to their validity to assess absence of prolonged thirst), have a much larger influence on integrated scores than health-related measures such as ‘mortality rate’ and ‘lameness score’. Hence, the integration method of the WQ protocol for dairy cattle should be revised to ensure that the relative contribution of the various welfare measures to the integrated scores more accurately reflect their relevance for dairy cattle welfare.

Our clinical experience at a specialized brain injury clinic suggests that numerous patients with traumatic brain injury (TBI) are using cannabis to alleviate their symptoms. While this patient population often inquires about the evidence of using cannabis post-head injury for the neurosensory, neurocognitive, and neuropsychiatric sequelae, most health professionals have little to no knowledge of this evidence. Given the recent legalization of recreational cannabis in Canada, questions and guidance related to cannabis use following a TBI are likely to become more common. This article reviews the evidence for cannabis use in psychiatric disorders with or without TBI. Overall, we found that the evidence for the use of cannabis among TBI patients is sparse and that patients tend to have little knowledge of the proven benefits and diverse effects of cannabis use. We feel this paper can serve as a stepping stone for future studies that explore the impact of cannabis use in a TBI population and can guide clinicians in advising their patients.

Dans cette contribution, nous nous intéressons à l'origine et au développement de la construction [adverbe de degré + nom]: C'est très théâtre, c'est-à-dire très faux. De nos jours, cette construction se présente comme un puissant outil de recatégorisation contextuelle pour exprimer un rapport de ressemblance basé sur une analogie avec un concept nominal. Sur la base d'une recherche de corpus outillée, nous montrons que la construction-hôte [ADVdegré + ADJ] a pu s'ouvrir à la catégorie nominale à partir d'un petit noyau dur de noms humains, en partie qualitatifs, tirant profit de certaines propriétés structurelles du français de l’époque. Par la suite, la construction s'est diversifiée vers d'autres classes sémantiques (noms inanimés, noms propres, etc.) et a progressivement attiré une gamme plus diversifiée de types lexicaux dans son orbite. Elle n'a cessé de gagner en productivité, tout en réduisant son fonds lexical d'origine à la portion congrue.

La présente contribution porte sur tourner et virer, deux verbes attributifs (p. ex. elle a viré/tourné folle) qui ne sont pas encore reconnus pleinement par la tradition grammaticale normative ni dans les travaux des linguistes. Elle vise à établir le profil distributionnel / collocationnel de ces deux verbes qui semblent opérer dans le même domaine sémantico-fonctionnel, afin de mettre à nu les subtiles divergences au niveau de leur profil sémantique. Celles-ci sont rattachées à la sémantique de base du verbe lexical, laissant entrevoir dans ces emplois grammaticalisés des effets dus à la « persistance lexicale » (lexical persistence). Afin d'objectiver au maximum les profils distributionnels des deux verbes (et partant leur profil sémantique), les outils statistiques offerts par la méthode collostructionnelle (Stefanowitsch et Gries 2003; Gries et Stefanowitsch 2004) sont mis à profit. En outre, la combinaison de l'approche collocationnelle et de l'analyse morphosyntaxique amène à distinguer l'emploi proprement attributif des deux verbes d'un emploi directionnel abstrait homonymique (l'entreprise a viré solaire), qui est encore proche de la construction prépositionnelle (virer à / tourner à).

The aim of this paper is threefold: descriptive, methodological and theoretical. It offers a distinctive collexeme analysis of two pairs of near-synonymous complex prepositions (sous le coup de SN/sous le choc de SN; sous l’emprise de SN/sous l’empire de SN), completed by a qualitative analysis. The analysis of the statistically significant co-occurrents suggests that sous le coup de has a more abstract and general meaning than sous le choc de, while the semantics of the second pair are less differentiated. The analysis touches upon several methodological issues; thus, examination of the problem addressed allows for assessment of the method. It also shows that the collostructional analysis offers an interesting contribution to the debate on the existence of a constructional semantics by identifying repelled collexemes that may yield coercion effects.

Efficiency analysis is used for assessing links between technical efficiency (TE) of livestock farms and animal diseases. However, previous studies often do not make the link with the allocation of inputs and mainly present average effects that ignore the often huge differences among farms. In this paper, we studied the relationship between exposure to gastrointestinal (GI) nematode infections, the TE and the input allocation on dairy farms. Although the traditional cost allocative efficiency (CAE) indicator adequately measures how a given input allocation differs from the cost-minimising input allocation, they do not represent the unique input allocation of farms. Similar CAE scores may be obtained for farms with different input allocations. Therefore, we propose an adjusted allocative efficiency index (AAEI) to measure the unique input allocation of farms. Combining this AAEI with the TE score allows determining the unique input-output position of each farm. The method is illustrated by estimating efficiency scores using data envelopment analysis (DEA) on a sample of 152 dairy farms in Flanders for which both accountancy and parasitic monitoring data were available. Three groups of farms with a different input-output position can be distinguished based on cluster analysis: (1) technically inefficient farms, with a relatively low use of concentrates per 100 l milk and a high exposure to infection, (2) farms with an intermediate TE, relatively high use of concentrates per 100 l milk and a low exposure to infection, (3) farms with the highest TE, relatively low roughage use per 100 l milk and a relatively high exposure to infection. Correlation analysis indicates for each group how the level of exposure to GI nematodes is associated or not with improved economic performance. The results suggest that improving both the economic performance and exposure to infection seems only of interest for highly TE farms. The findings indicate that current farm recommendations regarding GI nematode infections could be improved by also accounting for the allocation of inputs on the farm.

We address the question, in decision theory, of how the value of risky options (gambles) should be assessed when they have no finite standard expected value, that is, where the sum of the probability-weighted payoffs is infinite or not well defined. We endorse, combine and extend (1) the proposal of Easwaran (2008) to evaluate options on the basis of their weak expected value, and (2) the proposal of Colyvan (2008) to rank options on the basis of their relative expected value.

During the last week of May 1986, a 1-week prospective study on antibiotic utilization in surgical patients was held in 104 (42%) of the 247 Belgian acute care hospitals. All surgical patients with a post-operative stay of at least 3 days were studied, involving 3112 patients. Each patient was observed for 7 days, starting from the day before surgery. Antibiotics were administered to 71·9% of all patients; 21·9% received therapeutic antibiotics and 52·9% prophylactic antibiotics; 2·9% received both. Of the 1285 patients undergoing a surgical procedure with no indication for antimicrobial prophylaxis, 50·7% nevertheless received prophylaxis; 92·8% of patients with a generally recognized indication for prophylaxis received antibiotic prophylaxis. Less than one fifth (17·1 %) of all prophylactic courses were stopped on the day of the intervention whilst 26·3% were continued up to the fifth post-operative day or beyond. The most frequently prescribed drugs for this indication included first and second generation cephalosporins and nitroimidazoles. The number of different generic drugs utilized per hospital ranged from 1 to 18 (mean: 7·7).

This paper uses a Markov chain model to analyse the dynamics in farm-size distribution among the Flemish dairy sector and the impact of quota policy regulation on such changes. The model predicts a decline of 24% in number of farms in 2014 compared with the current situation with a more liberal exchange policy and a decline of 18% with a restricted quota exchange policy. From these Markov chain model results, we analysed the impact of farm-size distribution on eight different milk quality parameters (total bacterial count, somatic cell count, coliform count, freezing point, urea-N, fat content and protein content and penalty-points). In general, larger farms produce higher quality milk than smaller farms, especially with respect to the microbiological parameters (total bacterial count, somatic cell count and coliform count). The change in farm-size distribution from a liberal quota exchange policy would decrease the average total bacterial count by 18·0%, the somatic cell count by 2·1% and the coliform count by 11·0%. The aggregate performance of the other parameters are smaller with improvements in all cases of <1%.

Many people believe that we have responsibility towards the distant future, but exactly how far this responsibility reaches and how we can find a reasonable ethical foundation for it has not been answered in any definitive manner. Future people have no power over us, they form no part of our moral community and it is unclear how we can represent them in a possible original position. All these problems can be circumvented when you take an impersonal decision criterion like maximizing total or average utility. Such a sum-ranking criterion is neutral with respect to distance in time or space: my utility, my neighbour's and that of our descendants all carry the same weight. This makes future people an integral part of present decisions. Time-neutrality was defended by, among others, Sidgwick, Pigou and Ramsey.

Dans cette contribution, nous proposons une analyse des noms attributs inanimés dépourvus de déterminant. Partant d'une typologie globale des emplois attestés dans Frantext, nous nous concentrerons surtout sur les emplois nominaux ‘productifs’, c'est-à-dire les emplois nominaux qui ne sont ni figés (X est fonction de), ni liés à une série d'items lexicaux particuliers (X est affaire/question…de). Il s'avère que les emplois nominaux se situent entre deux pôles sémantiques, qui correspondent à deux profils syntaxiques: un pôle [+ catégorisation] (Bruxelles est capitale de l'Europe) et un pôle [+ association conceptuelle] (Dieu est amour; un visage qui fut révélation). Le premier pôle se trouve dans le prolongement de la construction prédicative des noms humains (Pierre est médecin) et constitue l'interprétation par défaut. Les emplois se rattachant au second pôle se fondent sur un calcul inférentiel.
