‘Instruments for Everyone’: Empowering disabled creators with tools for musical expression
Authors: Rodrigues Paulo Maria , Gehlhaar Rolf , Girao Luis Miguel , Penha Rui 
Published: December 2013

Abstract
This article reports a project commissioned by the Education Service of Casa da Música (CdM) in which tools were developed to allow musical expression by physically and mentally challenged people. The first phase involved defining a group of clients, identifying their capabilities and motivations and designing customized solutions involving different combinations of software and hardware. The second phase consisted of a programme of regular activities using these resources in their institutions. The third phase involved the composition of a piece of music using those resources along with others and its performance by these people in the main concert hall of CdM in April 2010. ‘Viagem’, a piece written for, and performed by, a group of about 80 people with mixed abilities proved the concept, but it was, above all, a deep artistic experience.

How far out is ‘out’? On the grammatical functions of the Estonianvälja‘out’
Authors: Huumo Tuomas , Lehismets Kersten 
Published: December 2013

AbstractAmong the typologically agglutinative Finno-Ugric languages, Estonian is in many ways exceptional since it has developed a long way towards the analytic type. One indicator of this is the extensive use of particles and adverbs to indicate grammatical relations such as aspect. Our paper discusses, in a Cognitive Grammar framework, the grammatical functions of the adverbvälja‘out’, which is originally an illative (‘into’) case form of the lexical nounväli‘field’. Our study shows how the meanings evolve along a continuum from concrete senses to more abstract ones, and we set out to find motivations for the development. The formväljahas developed numerous usages as an adverb and a verb particle. Its concrete spatial meaning is that of indicating a relation where a mover exits a (typically three-dimensional) container and moves from its inside to its outside. The abstract functions of this multi-functional gram include the following ones: 1) a change in the cognitive state of an animate participant (e.g., as the result of acquiring information), 2) changes-of-state metaphorically represented as motion out of a container, 3) terminative direction or distance (‘all the way to X’) and 4) perfective aspect. We argue that a crucial factor in the development of these functions is the placement of the conceptualizer's viewpoint either inside or outside the container which the mover exits. A viewpoint outside the container means that in the initial configuration the mover is hidden from the conceptualizer's view, and when exiting the container it becomes accessible to the conceptualizer. This meaning motivates abstract functions whereväljaindicates incipient availability or accessibility of the mover. On the other hand, a viewpoint situated inside the container results in the meaning where the mover (that exits the container) escapes from the conceptualizer's view, or, in abstract expressions, its cognitive dominion. This motivates the use of the gram in many expressions of a change of state, and in particular builds a link to its aspectual functions where it indicates the spatiotemporal extent of an event or an entity by measuring the distance from the starting point of such (concrete or metaphorical) motion.
The role of working memory in the comprehension of unfamiliar and familiar metaphors
Authors: Mashal Nira 
Published: December 2013

AbstractComprehension of unfamiliar metaphors (mercy blanket) is an effortful cognitive process that requires the formation of a novel metaphoric mapping between two disparate domains during which irrelevant properties have to be suppressed. The present study aims to examine the relationship between the comprehension of both unfamiliar and familiar metaphors and working memory. Three experiments were conducted: a comprehension task (Experiment 1), a recognition task (Experiments 2a and 2b), and a free recall task (Experiment 3). In the first experiment comprehension of both unfamiliar and familiar metaphors correlated with digit span backward but not with digit span forward. Results of the second experiment revealed that unfamiliar metaphors induced a higher rate of semantic errors relative to phonological errors, whereas familiar metaphors induced the same number of phonological and semantic errors. The third experiment confirmed that unfamiliar metaphors were harder to recall than were familiar metaphors. These findings show that working memory capacity may be involved in the computation of unfamiliar metaphoric interpretations, and more specifically in the process of suppressing irrelevant information via the central executive. Familiar metaphor recognition may rely on either phonological codes that are maintained in the phonological loop or on semantic processing that involves long term storage.

Published: December 2013

OBJECTIVE:To evaluate the accuracy of the Edinburgh Postnatal Depression Scale (EPDS) and 3 subscales for identifying postpartum depression among primiparous adolescent mothers.METHODS:Mothers enrolled in a randomized controlled trial to prevent postpartum depression completed a psychiatric diagnostic interview and the 10-item EPDS at 6 weeks, 3 months, and 6 months postpartum. Three subscales of the EPDS were assessed as brief screening tools: 3-item anxiety subscale (EPDS-3), 7-item depressive symptoms subscale (EPDS-7), and 2-item subscale (EPDS-2) that resemble the Patient Health Questionnaire-2. Receiver operating characteristic curves and the areas under the curves for each tool were compared to assess accuracy. The sensitivities and specificities of each screening tool were calculated in comparison with diagnostic criteria for a major depressive disorder. Repeated-measures longitudinal analytical techniques were used.RESULTS:A total of 106 women contributed 289 postpartum visits; 18% of the women met criteria for incident postpartum depression by psychiatric diagnostic interview. When used as continuous measures, the full EPDS, EPDS-7, and EPDS-2 performed equally well (area under the curve &gt;0.9). Optimal cutoff scores for a positive depression screen for the EPDS and EPDS-7 were lower (≥9 and ≥7, respectively) than currently recommended cutoff scores (≥10). At optimal cutoff scores, the EPDS and EPDS-7 both had sensitivities of 90% and specificities of &gt;85%.CONCLUSIONS:The EPDS, EPDS-7, and EPDS-2 are highly accurate at identifying postpartum depression among adolescent mothers. In primary care pediatric settings, the EPDS and its shorter subscales have potential for use as effective depression screening tools.
Integrated Management of Canada Thistle (Cirsium arvense) with Insect Biological Control and Plant Competition under Variable Soil Nutrients

Published: December 2013

AbstractBecause of economic and environmental constraints, alternatives to chemical management of Canada thistle (Cirsium arvense) are frequently sought, but adequate nonchemical suppression of this invasive species remains elusive. Combining biological control with other tactics may be an effective approach to suppress Canada thistle, but more information is needed about how environmental conditions affect interspecific interactions. We investigated effects of a biocontrol agent (Hadroplontus litura, a stem-mining weevil) and a potential plant competitor (common sunflower, Helianthus annuus, native annual) on Canada thistle under two soil nutrient regimes in outdoor microcosms. Larval mining damage was relatively light, and weevils negatively impacted only main shoot height and flower number. All measures of Canada thistle performance were reduced when plants were grown with common sunflower or in reduced nutrients, although effects of the latter on root biomass were not significant. Effects of common sunflower and soil nutrients on Canada thistle were generally additive, though a marginally insignificant interaction indicated a trend for greatest flower number with high nutrients and absence of common sunflower. Effects of weevils and common sunflower on Canada thistle were also additive rather than interactive. Although larval damage ratings were significantly greater on plants grown in high-nutrient soil, under our experimental conditions weevils and soil nutrients did not have a significant interactive effect on Canada thistle plants. Our results indicate that H. litura is a relatively weak biological control agent, but when combined with competitive desirable vegetation, some level of Canada thistle suppression may be possible, especially if soil nutrient levels are not highly enriched from agricultural runoff. Assessing the true ecological impacts of Canada thistle infestations may be an important direction for future research.
Integration of Prescribed Burning, Aminopyralid, and Reseeding for Restoration of Yellow Starthistle (Centaurea solstitialis)-Infested Rangeland

Published: December 2013

AbstractYellow starthistle (Centaurea solstitialis) is among the most invasive plant species in the western United States. The long-term management of yellow starthistle should include an integrated approach that incorporates establishment of competitive vegetation. In this study, conducted in two locations at Fort Hunter Liggett in Monterey County, California, we evaluated the combination of prescribed burning, the herbicide aminopyralid, and reseeding of native broadleaf and grass species on both yellow starthistle control and native plant restoration. Both study sites were burned in late October 2009. Over the following season, aminopyralid was applied at three timings and native plant species were seeded at three timings, using both a drill-seeder and broadcast spreader. Evaluations over the next 3 yr showed that aminopyralid provided complete to nearly complete control of yellow starthistle when applied between January and March, and this level of control was maintained for two seasons. Native plants failed to establish when broadcast seeded, regardless of the timing. December and January drill seeding timings were the most successful in establishing native species. There was a strong herbicide and drill seed timing interaction effect on native grass cover at both study sites. Over the course of the study the native perennial grass Stipa cernua was the most successful seeded species to establish, but establishment was slow and required 3 yr. Our results indicate that a January or March aminopyralid treatment integrated with a native perennial grass drill seeding program in January offers the greatest probability of both successful yellow starthistle control and perennial grass establishment.
Impacts of Prescribed Fire, Glyphosate, and Seeding on Cogongrass, Species Richness, and Species Diversity in Longleaf Pine

Published: December 2013

AbstractCogongrass [Imperata cylindrica (L.) Beauv.] is a warm-season, rhizomatous grass native to southeast Asia that has invaded thousands of hectares in the southeastern United States. Its negative impacts on pine forests have been well documented, and aggressive control is widely recommended. Although repeated herbicide treatments are effective for suppression, integrated strategies of prescribed burning coupled with herbicide treatment and revegetation are lacking in pine systems. In particular, longleaf pine forests, which are typically open, fire-dependent, communities, are highly susceptible to cogongrass, which is a pyrogenic species. To address management goals for cogongrass control and herbaceous restoration in longleaf pine forests better, field studies were conducted in southwestern Alabama from 2010 to 2012. Two longleaf pine forests with near-monotypic stands of cogongrass in the understory were selected for study. Treatments included combinations of winter prescribed fire, spring and fall glyphosate herbicide treatments, and seeding a mix of native, herbaceous species. Data were collected for three growing seasons following study initiation, and included seasonal herbaceous species cover and final cogongrass shoot and rhizome biomass. Species richness and diversity were calculated and analyzed to ascertain treatment effects over the duration of the study. Burning slightly improved cogongrass control with glyphosate, but had no effect on total cover, species richness, or species diversity. Three glyphosate treatments reduced total vegetative cover and nearly eliminated cogongrass cover, shoot, and rhizome biomass. Glyphosate and glyphosate + seeding also increased herbaceous species richness and diversity. However, aboveground productivity in treated plots was significantly lower than productivity in the untreated control, which was almost exclusively cogongrass. These studies indicate that glyphosate and integrated strategies utilizing glyphosate and seeding are very useful for cogongrass management and increasing herbaceous species richness and diversity in longleaf pine.

Published: December 2013

AbstractDowny brome is a problematic invasive annual grass throughout western rangeland and has been increasing its abundance, spread, and impacts across Montana during the past several years. In an effort to develop effective management recommendations for control of downy brome on Montana rangeland, we compiled data from 24 trials across the state that investigated efficacy of imazapic (Plateau®, BASF Corporation, Research Triangle Park, NC) applied at various rates and timings and with methylated seed oil (MSO) or a nonionic surfactant (NIS). We ran a mixed-model ANOVA to test for main effects and interactions across application rate (70, 105, 141, 176, and 211 g ai ha−1), application timing (preemergent [PRE], early postemergent [EPOST, one- to two-leaf growth stage], and postemergent [POST, three- to four-leaf growth stage]), and adjuvant (MSO, NIS). Application timing and rate interacted to affect downy brome control (P = 0.0033). PRE imazapic application resulted in the lowest downy brome control (5 to 19%), followed by POST application (25 to 77%) and EPOST application (70 to 95%). Downy brome control remained fairly consistent across rates within application timing. Adjuvant (MSO or NIS) did not affect downy brome control (P = 0.2789). Our data indicate that POST application at 105 to 141 g ai ha−1 provides the most-consistent, short-term control of downy brome. Furthermore, applying imazapic to downy brome seedlings shortly after emergence (one- to two-leaf growth stage) provided better control than applying it to older downy brome seedlings (three- to four-leaf growth stage).

Abstract
Peptide–MHC (pMHC) multimers have become one of the most widely used tools to measure Ag-specific T cell responses in humans. With the aim of understanding the requirements for pMHC-based personalized immunomonitoring, in which individuals expressing subtypes of the commonly studied HLA alleles are encountered, we assessed how the ability to detect Ag-specific T cells for a given peptide is affected by micropolymorphic differences between HLA subtypes. First, analysis of a set of 10 HLA-A*02:01–restricted T cell clones demonstrated that staining with pMHC multimers of seven distinct subtypes of the HLA-A*02 allele group was highly variable and not predicted by sequence homology. Second, to analyze the effect of minor sequence variation in a clinical setting, we screened tumor-infiltrating lymphocytes of an HLA-A*02:06 melanoma patient with either subtype-matched or HLA-A*02:01 multimers loaded with 145 different melanoma-associated Ags. This revealed that of the four HLA-A*02:06–restricted melanoma-associated T cell responses observed in this patient, two responses were underestimated and one was overlooked when using subtype-mismatched pMHC multimer collections. To our knowledge, these data provide the first demonstration of the strong effect of minor sequence variation on pMHC-based personalized immunomonitoring, and they provide tools to prevent this issue for common variants within the HLA-A*02 allele group.

Published: December 2013

SummaryThroughout the last two decades inflammation has been recognized as the central mechanism underlying atherogenesis. A multitude of basic science work demonstrates the pivotal role of inflammatory processes during every step of atherosclerotic plaque formation: From initiation via propagation to complication.This review describes some of the key mechanisms involved with a particular focus on the diverse group of inflammatory cells and their subsets that distinctly contribute to atherogenic and anti-atherogenic phenomena. Furthermore, we summarize the controlling action of a tight network of co-stimulatory molecules and cytokines orchestrating the inflammatory and anti-inflammatory effector functions. Finally, the current status of clinical trials evaluating anti-inflammatory/ immune-modulatory treatment strategies is summarized and an outlook for future therapeutic implications is provided.
La publicité et la signalisation des droits de propriété intellectuelle : un encadrement à parfaire
Authors: Verville Sophie 
Published: December 2013

Dans le présent article, l’auteure s’intéresse à certains problèmes soulevés par les moyens permettant de signaler les droits intellectuels aux tiers. Le Canada et les États-Unis tiennent des registres de publicité volontaires pour les marques de commerce et les droits d’auteur, mais des registres obligatoires pour les brevets et les dessins industriels. Par ailleurs, les pratiques de marquage (copyright, tous droits réservés : © ; marque déposée : MD ou ®, etc.) n’y sont que partiellement encadrées. Par contraste, la France ne tient aucun registre de publicité pour les droits d’auteur, mais l’enregistrement des brevets, des dessins et modèles puis des marques y est requis. Le marquage semble ne pas y avoir de portée juridique. Or, le droit de la propriété intellectuelle est complexe et même réputé pour la lourdeur des litiges qui l’animent. L’auteure soutient que la prévention des litiges et le principe de l’effet erga omnes des protections seraient beaucoup mieux servis par un encadrement plus rigoureux des moyens permettant d’informer les tiers.
Flottements du droit − Note sur l’écriture juridique
Authors: Forray Vincent 
Published: December 2013

Ce bref essai voudrait inviter à prendre en considération le phénomène d’écriture juridique, c’est-à-dire le mode privilégié de formalisation du droit dans les sociétés occidentales contemporaines. Pour cela, il développe une idée simple à première vue : puisque le droit se présente à nous dans des textes, la composition de ces textes conditionne la manière d’être du droit. Or l’écriture du droit, quel que soit l’auteur du texte, quel que soit le type du texte, connaît certaines contraintes qui influent, par conséquent, sur le droit lui-même. Il apparaît donc que l’écriture juridique est un acte constitutif du droit. Plus encore, il s’agit d’un acte constitutif de certaines des équivoques, de certaines des ambivalences, bref, des flottements caractéristiques du droit. En établissant ainsi l’enjeu de la textualisation du droit, cet article plaide pour faire de l’écriture juridique un objet d’étude.
On the effect of the East/Japan Sea SST variability on the North Pacific atmospheric circulation in a regional climate model
Authors: Seo Hyodae , Kwon Young‐Oh , Park Jong‐Jin 
Published: December 2013

AbstractThe East/Japan Sea (EJS) is a semi‐enclosed marginal sea located in the upstream of the North Pacific storm track, where the leading modes of wintertime interannual variability in sea surface temperature (SST) are characterized by the basin‐wide warming‐cooling and the northeast‐southwest dipole. Processes leading to local and remote atmospheric responses to these SST anomalies are investigated using the Weather Research and Forecast (WRF) model. The atmosphere in direct contact with anomalous diabatic forcing exhibits a linear and symmetric response with respect to the sign, pattern, and magnitude of SST anomalies, producing increased (decreased) wind speed and precipitation response over warm (cold) SSTs. This local response is due to modulation of both the vertical stability of the marine atmospheric boundary layer and the adjustment of sea level pressure, although the latter provides a better explanation of the quadrature relationship between SST and wind speed. The linearity in the local response suggests the importance of fine‐scale EJS SSTs to predictability of the regional weather and climate variability. The remote circulation response, in contrast, is strongly nonlinear. An intraseasonal equivalent barotropic ridge emerges in the Gulf of Alaska as a common remote response independent of EJS SST anomalies. This downstream blocking response is reinforced by the enhanced storm track variability east of Japan via transient eddy vorticity flux convergence. Strong nonlinearity in remote response implies that detailed EJS SST patterns may not be critical to this downstream ridge response. Overall, results demonstrate a remarkably far‐reaching impact of the EJS SSTs on the atmospheric circulation.
