Well-validated reference values are necessary for a correct interpretation of a serum PTH concentration. Establishing PTH reference values needs recruiting a large reference population. Exclusion criteria for this population can be defined as any situation possibly inducing an increase or a decrease in PTH concentration. As recommended in the recent guidelines on the diagnosis and management of asymptomatic primary hyperparathyroidism, PTH reference values should be established in vitamin D-replete subjects with a normal renal function with possible stratification according to various factors such as age, gender, menopausal status, body mass index, and race. A consensus about analytical/pre-analytical aspects of PTH measurement is also needed with special emphasis on the nature of the sample (plasma or serum), the time and the fasting/non-fasting status of the blood sample. Our opinion is that blood sample for PTH measurement should be obtained in the morning after an overnight fast. Furthermore, despite longer stability of the PTH molecule in EDTA plasma, we prefer serum as it allows to measure calcium, a prerequisite for a correct interpretation of a PTH concentration, on the same sample. Once a consensus is reached, we believe an important international multicentre work should be performed to recruit a very extensive reference population of apparently healthy vitamin D-replete subjects with a normal renal function in order to establish the PTH normative data. Due to the huge inter-method variability in PTH measurement, a sufficient quantity of blood sample should be obtained to allow measurement with as many PTH kits as possible. [less ▲]

Architects express themselves graphically in order to communicate ideas both to clients and to themselves. In practice, they rely on a variety of representations such as free-hand drawings, 3D computer rendered images, and photomontages to convey their design intent. Research to date has demonstrated differences and commonalities in the ways in which expert designers and laymen perceive visual understanding. It is still unclear how architects themselves use different types of representations to express different intentions, and how accurately their expected audience perceives those intentions. The purpose of this research is to investigate how laymen interpret the initial design intent of an architect’s design, and what role different forms of representations play in this process of understanding a design. This paper describes a five-step process for developing a survey that was used to gather data from 686 laymen respondents. It was found that certain types of simpler representations presented in specific contexts are unexpectedly found to be a more efficient way to faithfully transmit an architectural intent. [less ▲]

Parmi les nombreux types de scène qui ornent les pinakes de Locres (Italie du Sud, Calabre), il en est un qui a particulièrement intrigué les commentateurs. Il s’agit du type 3/6, qui présente une scène de sacrifice : devant un temple à l’intérieur duquel se trouvent deux statues divines, l’une féminine et l’autre masculine, un couple accomplit une libation sur un autel, sur lequel brûle une part de l’animal sacrificiel. Cette scène, qui est l’une des plus complexes du point de vue de la composition, est très particulière et isolée au sein du corpus des pinakes locriens, et ce pour plusieurs raisons. Le détail qui retiendra plus spécialement notre attention est celui de la scène figurée sur l’autel, qui est toujours décrite comme une scène érotique entre un satyre et un cervidé, et qui a donné lieu à une série d’interprétations diverses. Ce jeu d’image dans l’image – et plus spécifiquement d’autel porteur d’une image – est fréquent dans l’imagerie grecque, et se retrouve aussi sur d’autres pinakes. Mais la présence du satyre est tout-à-fait particulière et la portée de cette scène difficile à appréhender au sein de ce corpus en lien avec la sphère féminine et le rituel nuptial. On verra toutefois que, s’il est vrai qu’elle n’a visiblement pas eu beaucoup de succès (seuls cinq exemplaires sont attestés sur les 1200 qui composent le corpus), cette image n’est peut-être pas si étrange que cela, et ce qui apparaît au premier regard comme une scène "grossière" pourrait bien être en fait une ingénieuse métaphore, qui a entièrement sa place sur un pinax locrien.

The physiological role of the gastrointestinal microbiota has become an important subject of nutrition research in pigs in the past years, and the importance of intestinal microbial activity in the etiology of disease is doubtless. This review summarizes the recent knowledge related to the microbial ecology of protein fermentation and the appearance of protein-derived metabolites along the pig intestine. The amount of fermentable protein depends on factors such as dietary protein concentration, protein digestibility due to secondary or tertiary structure, the interaction with dietary compounds or anti-nutritional factors, and the secretion of endogenous proteins into the gut lumen. High protein diets increase the luminal concentrations and epithelial exposure to putatively toxic metabolites and increase the risk for post-weaning diarrhea, but the mechanisms are not yet clarified. Although the use of fermentable carbohydrates to reduce harmful protein-derived metabolites in pigs is well-established, recent studies suggest that the inclusion of fermentable carbohydrates into diets with low protein digestibility or high dietary protein level may not ameliorate all negative effects with regard to epithelial response. Based on the current knowledge, the use of diets with low levels of high-quality protein may help to reduce the risk for intestinal disease in young pigs. [less ▲]

Les politiques actives du marché du travail se développent en Belgique, depuis une vingtaine d’années, sous l’influence des institutions européennes et de l’Organisation de Coopération et de Développement Économique (OCDE). Ces politiques visent explicitement le développement de l’employabilité des chômeurs, entendons par là leur capacité d’insertion socioprofessionnelle, leurs chances d’accéder à un emploi durable et de qualité. En Belgique, la Stratégie européenne pour l’emploi se traduit dans le cadre d’accords (suc- cessifs) de coopération entre l’État fédéral et les Régions, relatifs à l’accompagnement et au suivi actifs des chômeurs. Ces politiques confèrent aux intermédiaires (publics et privés) du marché du travail un rôle central dans l’activation des chômeurs (conseil, orientation, formation, coaching, etc.). Nous proposons dans ce texte d’interroger l’activité des intermédiaires publics au travers d’une étude de cas centrée sur les « facilitateurs » de l’Office National de l’Emploi (ONEm) et les « conseillers emploi » du FOREm et d’ACTIRIS1.

A chemically cross-linked but remarkably (re)processable shape-memory polymer (SMP) is designed by cross-linking poly(ε -caprolactone) (PCL) stars via the efficient triazolinedione click chemistry, based on the very fast and reversible Alder– ene reaction of 1,2,4-triazoline-3,5-dione (TAD) with indole compounds. Typically, a six-arm star-shaped PCL function- alized by indole moieties at the chain ends is melt-blended with a bisfunctional TAD, directly resulting in a cross-linked PCL-based SMP without the need of post-curing treatment. As demonstrated by the stress relaxation measurement, the labile character of the TAD–indole adducts under stress allows for the solid-state plasticity reprocessing of the permanent shape at will by compression molding of the raw cross-linked material, while keeping excellent shape-memory properties.

L'explication proposée repose sur la thèse selon laquelle, dans une figure comportant des angles de différentes grandeur (réellement dessinés ou tracés par l'esprit), les angles plus petits sont surestimés et les angles plus grands sous-estimés, ce qui entraîne une estimation différente de la distance les séparant.

In European legal scholarship, many articles discuss the equilibrium reached in the case-law of the Court of Justice of the European Union (“CJEU”) when the EU antitrust prohibitions apply to, and restrain, the free and ordinary use of intellectual property rights (“IPRs”). We call this the antitrust-IP intersection. The most interesting feature of this literature is perhaps the common assumption that a unifying substantive perspective, vision or theory on IPR underpins the intersection point reached by the antitrust case-law. Whilst the theory of “absolutism” can be quickly disposed of, several other theories like inherency, exceptionalism or complementarity have been described as the lynchpin of the antitrust-IP intersection. Our paper offers a different reading of the case-law. It submits that the antitrust-IP intersection does not rest on any unitary theory which, in turn, bespeaks the Court’s vision of the social function of IPRs. Instead, the main feature of the CJEU case-law is that a specific methodology is applied to antitrust cases with IPR ramifications. The CJEU deals with most of such cases under a rule-based approach, instead of a standard-based approach. By rule-based approach, we refer to the ex ante setting of structured tests of liability, by opposition to ex post case-by-case resolution on grounds of a pre-determined, general standard (e.g., reasonableness, competition on the merits, efficiency, fairness, equity, etc.). As will be seen below, this approach has many virtues, not least in terms of legal certainty. But it also has a major qualification. Whilst the Court has consistently formulated rules of liability and justifiability at the antitrust and IP intersection, it has at the same time often embedded abstract standards within those rules. The implications of this mixed approach are unclear. [less ▲]

It has recently become possible to monitor patients’ voices outside the speech therapist’s office with a portable, easy-to-use tool: the voice dosimeter. This tool measures voice frequency and sound pressure level, as well as the duration of phonation, during a full day of regular activities. In addition to voice accumulation in an ecological context, the dosimeter used in this study (VoxLog, Sonvox) gives patients feedback on their voice use. In practice, the clinician configures the device so that it provides a vibratory signal in real time when the patient speaks above or below a predetermined frequency or sound pressure threshold. The feedback is intended to make patients aware of inappropriate vocal behavior and encourage them to change it. In this case study, we used biofeedback with the aim of reducing sound pressure level for a teacher suffering from vocal fold nodules. Our goal was to determine whether vibrotactile biofeedback applied in an ecological context for three consecutive weeks could reduce excess sound pressure. The feedback was activated every time the teacher spoke too loudly; its purpose was to help her avoid vocal abuse and (re)learn healthy vocal behaviors. This preliminary study generated encouraging results regarding the use of biofeedback in voice treatment. Nevertheless, it is important to investigate how this tool can best be implemented for patient management in speech language pathology. In addition, the method should be validated with randomized studies using a larger sample. [less ▲]

This contribution investigates the syntactic conceptions of, and the diagramming system introduced by, the American grammarian Stephen Watkins Clark (1847), who introduced the first comprehensive syntactic diagramming system. The structure of the English sentence is illustrated by agglutinated “bubbles” expressing the relations between words by the means of their relative position. The sentence consists of two or three horizontally aligned bubbles containing words that are called principal elements. These principal elements can be complemented with adjunct elements, that appear in bubbles attached below them. For grammatical words the conventions differ depending on whether the grammatical word is a preposition or a conjunction. Coordination is never named as such, but there is an orthogonal abstract relation that connects elements performing the same role in a “compound” construction. The system allows recursiveness in two different ways: by wrapping bubbles into other bubbles, thus following a mereological logic (part- whole relations) close to IC analysis or by hierarchically aggregating bubbles that resemble dependency trees. Clark's conceptions thus prefigure modern graphical formalizations. [less ▲]

Physical disturbances and resource pulses are major structuring drivers of terrestrial and aquatic ecosystems. The accumulations of exported dead leaves from the Neptune grass, Posidonia oceanica (L.) Delile are ephemeral and highly dynamic detrital habitats offering food sources and shelter for vagile macrofauna community. These habitats are frequently subject to wind and storms which can add “new” detrital material to previous accumulations; these can be defined as resource pulses and could potentially impact the associated macrofauna. This study assesses the impact of an experimental resource pulse on the macrofauna associated with exported P. oceanica litter accumulations. The experimental design consisted of two pulse treatments (the addition of dead leaves with and without the associated fauna), and two controls (one procedural, and one total control), where the added material was left underwater for 14 days. Invertebrates then present in the sampled detritus were all identified and counted. Our data suggest that the responses of these invertebrates to resource pulses present intermediate characteristics between aquatic and terrestrial ecosystems responses. Inputting a moderate amount of dead P. oceanica leaves into experimental mesocosms had a non-negligible impact and rapidly affected the macrofauna community. Specialist detritivores species were boosted while herbivore/detritivore species dramatically decreased. Predators also showed a modest but significant density increase, demonstrating the fast propagation of the pulse response throughout the entire community and through several trophic levels. Strict hypoxia-tolerant species were also only observed in the treated mesocosms, indicating the strong influence of resource pulses on physico-chemical conditions occurring inside litter accumulations.

En croisant plusieurs textes sur le montage et la juxtaposition d’images hétérogènes de l’essayiste et théoricien des médias allemand Hans Magnus Enzensberger, cet article met à jour un lien d’ordre esthétique entre divers dispositifs médiatiques passés et contemporains. L’identification de ce lien permet d’affranchir la critique théorique du paradigme évolutionniste de l’échec et du progrès (technologique et politique), pour l’ouvrir à un ensemble d’éclairages réciproques et non linéaires. Dans ce cadre, l’usage des textes d’Enzensberger dépasse, lui aussi, toute forme de périodisation. En faisant dialoguer son « Jeu de construction pour une théorie des médias » (1970), plusieurs essais rassemblés dans Médiocrité et folie (1988), ainsi que son récent entretien autobiographique Erinnerungen an einen Tumult (2014), ce texte montre comment la critique de l’auteur allemand, certes constamment redynamisée par l’apparition de « nouveaux » objets (presse tabloïd, vidéo portable, télévision, internet, smartphones), nous invite à dépasser tout déterminisme technologique pour penser en un même geste le potentiel politique des premiers groupes de vidéo engagée et des plateformes dominant internet aujourd’hui.
