Talaria: Continuous Drag & Drop on a Wall Display

International audienceWe present an interaction technique combining tactile actions and Midair pointing to access out-of-reach content on large displays without the need to walk across the display. Users can start through a Touch gesture on the display surface and finish Midair by pointing to push content away or inversely to retrieve a content. The technique takes advantage of wellknown semantics of pointing in human-to-human interaction.These, coupled with the semantics of proximal relations and deictic proxemics make the proposed technique very powerful as it leverages on well-understood human-human interaction modalities. Experimental results show this technique to outperform direct tactile interaction on dragging tasks. From our experience we derive four guidelines for interaction with large-scale displays

Biogeography of Endemic Dragonflies of the Ozark-Ouachita Interior Highlands

A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for rare or cryptic species. Further, priority status is often designated within geopolitical boundaries, which may include only a portion of a species range. This, coupled with lack of distributional data, has resulted in species being designated as apparently rare throughout some portions of their range, which may not accurately reflect their overall conservation need. The Interior Highlands region of the central United States harbors a rich diversity of flora and fauna, many of which are regional endemics. Among these are four dragonfly species considered Species of Greatest Conservation Need: Ouachita spiketail (Cordulegaster talaria), Ozark Emerald (Somatochlora ozarkensis), Westfall’s snaketail (Ophiogomphus westfalli), and Ozark clubtail (Gomphurus ozarkensis). I combined species distribution modeling with field surveys to better understand the current biogeography for the two species with ample presence data (S. ozarkensis and G. ozarkensis). Additionally, models were used to project species’ distributions under two climate change scenarios of differing severity. To assess reliability of model predictions, I used two machine learning algorithms commonly used with limited, presence-only data. Current areas of suitability predicted by both algorithms largely overlapped for each species. An analysis of variable contribution showed congruence in important environmental predictors between models. Field validation of these models resulted in new detections for both species showing their utility in guiding future surveys. Future projections across two climate change scenarios showed the importance of maintaining current suitable areas as these will continue to be strongholds for these species under climate change

Evaluation of cover crops in high tunnel vegetable rotation

Organic vegetable production within high tunnels allows for an extended growing season, crop protection, and environmental control. The USDA National Organic Program (NOP) standards mandate evidence that the soil has been maintained and improved over the course of production. Previous studies have indicated the potential of cover crops for reducing competitive vegetation, and improving soil quality, thus resulting in greater plant growth, nutrient uptake, and yield. However, there has been limited work in the confines of high tunnels as part of a tunnel-system rotation. Ten nitrogen-fixing and ten non-legume cover crops were established under a high tunnel and evaluated for their effects on the yield of ‘De Cicco’ broccoli (Brassica oleracea L. var. italica) and ‘Champion’ collards (Brassica oleracea L. var. acephala), aboveground biomass, and plant C and N contents. All treatments received recommended levels of appropriate certified organic fertilizers, water status was maintained, and vegetables received standard organic maintenance for insects and disease. The cover crops hairy indigo (Indigofera hirsuta L.), Catjang cowpea (Viana unguicalata L.), and Sunn hemp (Crotalaria juncea L.) consistently produced higher yields than Tifleaf III hybrid pearl millet (Pennisetum glaucum L.), Dairymaster brown midrib (BMR) hybrid grain sorghum (Sorghum spp.), and Wild Game Food sorghum (Sorghum bicolor L.). Nitrogenfixing legumes produced horticulturally significantly higher yields than the non-nitrogen-fixing grass species. This experiment demonstrated that not all cover crops are equal; they created variation in response. Cover crops provide a viable option for organic producers to maintain or improve soil quality over the course of production

A randomized trial evaluating an mHealth system to monitor and enhance adherence to pharmacotherapy for alcohol use disorders

BACKGROUND: Nonadherence to prescribed medication regimens is a substantial barrier to the pharmacological management of alcohol use disorders. The availability of low-cost, sustainable interventions that maximize medication adherence would likely lead to improved treatment outcomes. Mobile health (mHealth) technologies are increasingly being adopted as a method of delivering behavioral health interventions and represent a promising tool for adherence interventions. We are evaluating a cell-phone–based intervention called AGATE that seeks to enhance adherence with regular text-messaging. METHODS/DESIGN: A randomized controlled effectiveness trial in the context of an eight-week open label naltrexone efficacy trial delivered in a naturalistic clinical setting. Treatment-seeking heavy drinkers (N = 105) are currently being recruited and randomly assigned to the AGATE intervention or a control condition. Daily measures of alcohol use and medication side effects are being recorded via cell phone in both conditions. Additionally, participants randomized to the AGATE condition receive medication reminders via SMS text message according to a schedule that adjusts according to their level of adherence. DISCUSSION: Results from this trial will provide initial information about the feasibility and efficacy of mHealth interventions for improving adherence to alcohol pharmacotherapies. TRIAL REGISTRATION: NCT01349985

Arkansas Endemic Biota: An Update with Additions and Deletions

It has been over a decade since the publication of Robison and Allen (1995) that provided the definitive list of endemic flora and fauna of Arkansas. The present study brings up-to-date the endemic biota of the state. Since 1995, several new species have been described and new discoveries have been made, adding species to the state biota. Other species are deleted and new distributional information on other state endemics is presented. Specifically, 3 new plant species are added to the state list while 4 plant species are deleted. Sixteen new animal species/subspecies are added to the state list while numerous species are deleted. These changes bring to 110 (10 species of plants and 100 species/subspecies of animals) the total number of Arkansas state endemic plants and animals presently known, which represents a decrease by 7 species from the 117 species reported in 1995

Racionalización versus racionamiento en la práctica de la nutrición clínica; cuarta lección Jesús Culebras

La situación económica actual ha dado pie al tema de esta conferencia que se desarrollará en dos grandes apartados: primero, trataremos de ideas generales sobre la racionalización versus el racionamiento en la sanidad, y, posteriormente, del racionamiento en la práctica de la nutrición clínica. Racionalizar, según la Real Academia Española de la Lengua, es organizar la producción o el trabajo de manera que aumente los ren - dimientos o reduzca los costos con el mínimo esfuerzo. Mientras que por racionamiento se entiende la acción y efecto de racionar o limitar el consumo de algo para evitar consecuencias negativas. En Europa, el porcentaje del Producto Interior Bruto destinado a Sanidad cae progresivamente mientras el coste de la Sanidad no para de aumentar. Desde el punto de vista económico, éste sería el principal motivo por el que las autoridades sanitarias parece que no tienen más alternativa que racionar. ¿Hasta qué punto el principio ético de justicia es compatible con el racionamiento? Éticamente, parece que para aceptar el racionamiento debería cumplirse no sólo una distribución justa de los recursos limitados sino también el uso racional de los mismos. Si se acepta que el recorte en prestaciones sanitarias es necesario, deberíamos responder a diversas preguntas: ¿qué es lo ético no recortar?, ¿quién decide lo que es médicamente necesario?, ¿cómo se decide? Sin respuestas coherentes a estas preguntas resulta díficil, éticamente, aceptar el racionamiento a nivel sanitario. Al tratar el racionamiento en la práctica de la nutrición clínica, debemos centrarnos en cómo el racionamiento afecta a la desnutrición, y más concretamente de la desnutrición relacionada con la enfermedad, ya que ello centra el origen de la Nutrición Clínica. Por su importancia e implicaciones se están llevando a cabo, en diversos países entre ellos en España, acciones integradas en la estrategia de la Unión Europea: “Together for health: a Strategic Approach for the EU 2008-2013” encaminadas a tomar medidas dirigidas a prevenir y tratar la desnutrición. Pero a pesar de ello, las restricciones persisten, situándonos en la necesidad imperativa de utilizar todas las herramientas a nuestro alcance para prevenir el desarrollo de la desnutrición en los pacientes en riesgo, para detectar precozmente los pacientes con desnutrición o riesgo de desarrollarla y para establecer las medidas de actuación más adecuadas

How to produce more biomass for direct seeding mulched based cropping system in sub-saharian Africa ? Example in North Cameroun

In North Cameroon, from 2001 to 2006, more than 250 farmers tried direct seeding mulchbased cropping systems (DMC) in their fields. DMC systems were based on farmer traditional rotation i.e. cereal//cotton. Farmers compared on their own field cereals (maize, sorghum, millet) cultivated with conventional techniques and the same cereal conducted with DMC techniques i.e. : i) intercropped with a cover crop (Mucuna pruriens, Brachiaria ruziziensis, Crotalaria retusa, Vigna unguiculata, Dolichos lablab), ii) sowed without ploughing from the first or the second year of experimentation. Associations were made for the following objectives: i) produce aboveground biomass to produce mulch for the following crop (mainly cotton), ii) improve the soil's physical and chemical quality through the contribution of associated plants, iii) produce forage, iv) help to control weed, v) protect the soil surface against erosion and rain impacts, vi) produce grains for human or animals consumption. Each of the 5 cover crops used are different regarding their fulfilments of above objectives and their adaptation to North Cameroon local agro-climatic conditions (rainfall from 700 to 1200 mm). Thus, Brachiaria ruziziensis produces aboveground biomass in quantity (4-5 T of dry matter/ha even when associated with cereal) and quality (persisting of the mulch for over one year after production). Further, it seems to be very efficient in controlling Striga hermonthica and it is a good forage. However, it can impoverish the soil if its biomass is exported several times without any fertiliser or manure input. Crotalaria retusa is a nitrogen fixing legume and thus can improve soil fertility. Furthermore, this plant is non edible for cattle, which is an advantage for farmers who cannot protect their field from grazing during the dry season. C. retusa is also very efficient to fight against other weeds. Six years of experimentation with farmers permits us to produce practical recommendations for intercropping of cereals with cover crops: sowing date, crop type, tolerance to herbicides, limitation of competition with cereals, etc. This experimentation has also allowed us to see what is the behaviour of the 5 cover crops in farmer's conditions.

Urgencias neurológicas y guardias de Neurología

In recent years different studies have highlighted a progressive increase in the demand for neurological care in emergency departments. To analyze the convenience of specific neurology shifts or the role that the neurologist should play in the emergency department, it is necessary to answer questions such as: What is the demand for emergency neurological care? What are the most frequent neurological emergencies? Who should attend to neurological emergencies and why? Are specific neurology shifts necessary? Neurological emergencies account for between 2.6% and 14% of medical emergencies. Stroke represents a third of all neurological emergencies, while the diagnoses of acute cerebrovascular disease, epilepsy and cephalea constitute 50% of all neurological care in the emergency department. On the basis of quality of care criteria and professional competence, the best care for patients with a neurological emergency is provided by a specialist in neurology. The implementation of specific neurology shifts, with a 24 hour physical presence, is associated with greater quality of care, better diagnostic and therapeutic orientation from the moment the patient arrives in emergency department, reduces unnecessary admissions, reduces costs and strengthens the neurology service
