Commerce vertical et propagation des chocs de prix
Authors: Cochard Marion , Daudin Guillaume , Fronteau Sandra , Rifflart Christine
Published: March 2017

La décomposition des chaînes de valeur internationales est un aspect important de la mondialisation. Partant d’une hypothèse d’inflation par les coûts, nous examinons la propagation des chocs d’offre sur les prix à partir des tableaux Input-Output mondiaux. Le modèle de Leontief adapté dans le cadre d’une économie monde nous permet d’analyser empiriquement l’impact de chocs de change et de productivité sur la zone euro et sur le reste du monde lorsque ces chocs émanent de la zone euro. Nous montrons que la diffusion des chocs opère principalement au premier tour et dépend de la part des inputs importés dans la production ou les exportations. En outre, les chocs de change sont en partie compensés par une modification des prix des inputs ce qui, en cas d’appréciation, limite la perte de compétitivité. L’ampleur de cette compensation n’est pas négligeable et elle est d’autant plus élevée que les pays de la zone euro sont ouverts. Elle est ainsi plus forte pour l’Allemagne (avec une élasticité des prix d’exportation à un choc de l’euro de -9 %) que pour la France (-8 %). L’impact des chocs de productivité est plus important que celui des chocs de change en raison d’un effet de résonance domestique avant leur diffusion internationale. Parmi les grands pays, l’Allemagne est celui qui bénéficie le plus des chocs positifs de productivité émanant des PECO hors zone euro : dans ce cas, l’élasticité de ses prix d’exportation est de 6 % contre 2,5 % pour la France.
L’arbitrage entre le salariat et le travail indépendant au prisme des théories de la firme
Authors: Baudry Bernard , Chassagnon Virgile
Published: March 2017

Cet article s’intéresse à une nouvelle forme d’organisation du travail, le crowdworking . Cette expression désigne le travail réalisé à partir de plateformes en ligne qui permettent à des individus d’accéder ( via internet) à des organisations (ou à des individus) pour résoudre des problèmes spécifiques et offrir des produits et des services en échange d’une rémunération. Notre problématique consiste à s’interroger sur le potentiel de développement de cette pratique et à repérer les enjeux que le crowdworking met en exergue pour l’analyse économique. Pour ce faire, nous analysons la question de l’arbitrage entre le salariat et le travail indépendant au prisme des grandes théories de la firme en distinguant deux catégories de plateformes, celles qui font appel à du travail peu qualifié et celles qui mobilisent du travail qualifié. Nous montrons que la théorie économique permet de dégager trois variables de cet arbitrage : la nature des actifs humains engagés, la séparabilité des tâches, et la nature des connaissances. L’étude de ces trois variables donne à voir une dynamique d’organisation du travail qui devrait, en principe, rester favorable au salariat donc à l’entreprise.

A FAST ADAPTIVE BALLOON ACTIVE CONTOUR FOR IMAGE SEGMENTATION
Authors: Nachour Abdelhafid , Ouzizi Latifa , Aoura Youssef
Published: March 2017

Active Contour Models (ACM) have been widely used for segmentation in many computer vision applications. These models are defined by an energy functional attached to an initial curve that evolves under some constraints to extract desired objects in the image. New models are proposed, and existing techniques are investigated and improved in different domains. Among these ACM, Balloon ACM is an edge-based model that adds a normal force as constraint making the curve to have more dynamic behaviors and more effectiveness in detecting objects boundary. However, some problems have been pointed out including segmentation of complex shape and high runtime processing. In this paper, we develop a new method -called Fast Adaptive Balloon (FAB)- sufficient to segment complex shape with lower computational complexity. The proposed definition for balloon force achieves satisfactory segmentation performance compared with other ACMs using both synthetic and medical images in two dimension. The results demonstrate the accuracy and effectiveness in segmentation besides the convergence speed.

Current assay deals with the preparation of alfajores with different levels (0 to 15%) of dehydrated fish mixture of salmon (10%) and tilapia (90%) to assess the sensorial characteristics and their centesimal composition and microbiological. Fish inclusion in alfajores did not affect the aroma, taste, texture, color and physical aspect, with scores ranging between 6.70 and 7.96 of a hedonic scale of 9 score. An average score of 4 in a 5-score purchasing intention scale was obtained, or rather, tasters would probably buy the product. In the case of centesimal composition, inclusion affected (p <0.05) humidity (between 2.74 and 3.40%) and ash (between 0.31 and 1.01%) rates, with a quadratic effect; protein (between 5.35 and 7.12%) with positive linear effect; carbohydrates (between 72.64 and 75.79%) with negative linear effect. There was no difference (p >0.05) in lipids and calorie rates in the alfajores. Results show that the inclusion of up to 15% of a dehydrated mixture of salmon (10%) and tilapia (90%) in alfajores was greatly accepted and improved their nutrition values. Further, the product was also within the microbiological standards required by Brazilian sanitary laws.

Leishmaniases are diseases caused by several Leishmania species. Leishmania (Viannia) braziliensis can cause localized cutaneous leishmaniasis (LCL), which heals spontaneously, or mucosal leishmaniasis (ML), characterized by chronic and intense inflammation and scanty parasitism. Annexin A1 (AnxA1) is a protein involved in modulation and resolution of inflammation through multiple mechanisms. In the present study, the role of AnxA1 was investigated in L. braziliensis–infected BALB/c mice. AnxA1 levels increased at the peak of tissue lesion and parasitism in infected mice. AnxA1 increased also after L. braziliensis infection of BALB/c (wild-type [WT]) bone marrow derived macrophages. Despite a lower parasite intake, parasite burden in bone marrow-derived macrophages from AnxA1−/− mice was similar to WT and associated with an early increase of TNF-α and, later, of IL-10. AnxA1−/− mice controlled tissue parasitism similarly to WT animals, but they developed significantly larger lesions at later stages of infection, with a more pronounced inflammatory infiltrate and increased specific production of IFN-γ, IL-4, and IL-10. AnxA1−/− mice also presented higher phosphorylation levels of ERK-1/2 and p65/RelA (NF-κB) and inducible NO synthase expression, suggesting that AnxA1 may be involved in modulation of inflammation in this model of experimental leishmaniasis. Finally, assessment of AnxA1 levels in sera from patients with LCL or ML revealed that ML patients had higher levels of serum AnxA1 than did LCL patients or control subjects. Collectively, these data indicate that AnxA1 is actively expressed during L. braziliensis infection. In the absence of AnxA1, mice are fully able to control parasite replication, but they present more intense inflammatory responses and delayed ability to resolve their lesion size.
Predicting Manual Therapy Treatment Success in Patients With Chronic Ankle Instability: Improving Self-Reported Function
Authors: Wikstrom Erik A. , McKeon Patrick O.
Published: March 2017

Context: 

Therapeutic modalities that stimulate sensory receptors around the foot-ankle complex improve chronic ankle instability (CAI)–associated impairments. However, not all patients have equal responses to these modalities. Identifying predictors of treatment success could improve clinician efficiency when treating patients with CAI.

Objective: 

To conduct a response analysis on existing data to identify predictors of improved self-reported function in patients with CAI.

Design: 

Secondary analysis of a randomized controlled clinical trial.

Setting: 

Sports medicine research laboratories.

Patients or Other Participants: 

Fifty-nine patients with CAI, which was defined in accordance with the International Ankle Consortium recommendations.

Intervention(s): 

Participants were randomized into 3 treatment groups (plantar massage [PM], ankle-joint mobilization [AJM], or calf stretching [CS]) that received six 5-minute treatments over 2 weeks.

Main Outcome Measure(s): 

Treatment success, defined as a patient exceeding the minimally clinically important difference of the Foot and Ankle Ability Measure–Sport (FAAM–S).

Results: 

Patients with ≤5 recurrent sprains and ≤82.73% on the Foot and Ankle Ability Measure had a 98% probability of having a meaningful FAAM–S improvement after AJM. As well, ≥5 balance errors demonstrated 98% probability of meaningful FAAM–S improvements from AJM. Patients <22 years old and with ≤9.9 cm of dorsiflexion had a 99% probability of a meaningful FAAM–S improvement after PM. Also, those who made ≥2 single-limb–stance errors had a 98% probability of a meaningful FAAM–S improvement from PM. Patients with ≤53.1% on the FAAM–S had an 83% probability of a meaningful FAAM–S improvement after CS.

Conclusions: 

Each sensory-targeted ankle-rehabilitation strategy resulted in a unique combination of predictors of success for patients with CAI. Specific indicators of success with AJM were deficits in self-reported function, single-limb balance, and <5 previous sprains. Age, weight-bearing–dorsiflexion restrictions, and single-limb balance deficits identified patients with CAI who will respond well to PM. Assessing self-reported sport-related function can identify CAI patients who will respond positively to CS.

Published: March 2017

From September 2013 to July 2014, several gold miners working in the tropical forest consulted the Maripasoula Health Center in French Guiana for edema and findings consistent with right-sided cardiac failure. Of the 42 cases of beriberi that were diagnosed, one patient died. The laboratory and clinical investigation demonstrated vitamin B1 deficiency in most of the patients tested. Furthermore, 30 of 42 patients responded favorably to 500 mg of intravenous or intramuscular thiamine supplementation. In addition, dietary investigation showed insufficient thiamine intake in these patients. We concluded that patients had acquired beriberi because of diet restrictions, hard labor, and infectious diseases, notably malaria. In 2016, cases were still being reported. We recommend screening for compatible symptoms in gold miners, thiamine supplementation, and nutritional intervention.

Rickettsial infections are recognized as important causes of fever throughout southeast Asia. Herein, we determined the seroprevalence to rickettsioses within rural and urban populations of northern Vietnam. Prevalence of individuals with evidence of prior rickettsial infections (IgG positive) was surprisingly low, with 9.14% (83/908) testing positive to the three major rickettsial serogroups thought to circulate in the region. Prevalence of typhus group rickettsiae (TG)–specific antibodies (6.5%, 58/908) was significantly greater than scrub typhus group orientiae (STG)– or spotted fever group rickettsiae (SFG)–specific antibodies (P < 0.05). The majority of TG seropositives were observed among urban rather than rural residents (P < 0.05). In contrast, overall antibody prevalence to STG and SFG were both very low (1.1%, 10/908 for STG; 1.7%, 15/908 for SFG), with no significant differences between rural and urban residents. These results provide data on baseline population characteristics that may help inform development of Rickettsia serological testing criteria in future clinical studies.

The safety and immunogenicity of four formulations of an investigational tetravalent dengue purified inactivated vaccine (DPIV), formulated at 1 or 4 μg with aluminum hydroxide (alum) or at 1 μg with an adjuvant system (AS01E or AS03B), were evaluated in a first-time-in-human, placebo-controlled, randomized, observer-blind, phase 1 trial in the continental United States. Two doses of vaccine or placebo were administered intramuscularly 4 weeks apart to 100 healthy adults 18–39 years of age, randomized 1:1:1:1:1 to receive one of four DPIV formulations or saline placebo. The response to a third dose was evaluated in a subset of nine participants remote from primary vaccination. Humoral immunogenicity was assessed using a 50% microneutralization assay. All DPIV formulations were well tolerated. No vaccine-related serious adverse events were observed through 12 months after the second vaccine dose. In all DPIV groups, geometric mean antibody titers peaked at Day 56, waned through 6 months after the second vaccine dose, and then stabilized. In the nine subjects where boosting was evaluated, a strong anamnestic response was observed. These results support continuation of the clinical development of this dengue vaccine candidate (clinicaltrials.gov: NCT01666652).
High Triatoma brasiliensis Densities and Trypanosoma cruzi Prevalence in Domestic and Peridomestic Habitats in the State of Rio Grande do Norte, Brazil: The Source for Chagas Disease Outbreaks?

Published: March 2017

A total of 2,431 Triatoma brasiliensis were collected from 39 populations of Paraíba (PB) and Rio Grande do Norte (RN) states, Brazil. In PB, Trypanosoma cruzi infection was not detected in either peridomestic or domestic vector populations. In contrast, in RN, T. brasiliensis was detected with high parasite prevalence in these ecotopes (30.7–40.0%). Moreover, peridomicile insect population densities were more than double the average densities of all other settings evaluated (19.17 versus < 8.94 triatomine/man-hour). Genotyped parasites evidenced a mix of T. cruzi lineages circulating in both peridomestic and sylvatic populations. Although vector control efforts have dramatically decreased Chagas disease transmission to humans, recent outbreaks have been detected in four municipalities of RN state. Our results clearly evidence a worrisome proximity between infected vectors and humans in RN. Indeed, finding of infected T. brasiliensis inside homes is routinely recorded by local vector control surveillance staff around the outbreak area, challenging the current and conventional view that vector transmissions are controlled in northeastern Brazil. This scenario calls for strengthening vector control surveillance and interventions to prevent further Chagas transmission, especially in RN State.
“Back to Bedside”: Residents' and Fellows' Perspectives on Finding Meaning in Work
Authors: Hipp Dustin M. , Rialon Kristy L. , Nevel Kathryn , Kothari Anai N. , Jardine LCDR Dinchen A.
Published: March 2017

Background

Physician burnout is common and associated with significant consequences for physicians and patients. One mechanism to combat burnout is to enhance meaning in work.

Objective

To provide a trainee perspective on how meaning in work can be enhanced in the clinical learning environment through individual, program, and institutional efforts.

Methods

“Back to Bedside” resulted from an appreciative inquiry exercise by 37 resident and fellow members of the ACGME's Council of Review Committee Residents (CRCR), which was guided by the memoir When Breath Becomes Air by Paul Kalanithi. The exercise was designed to (1) discover current best practices in existing learning environments; (2) dream of ideal ways to enhance meaning in work; (3) design solutions that move toward this optimal environment; and (4) support trainees in operationalizing innovative solutions.

Results

Back to Bedside consists of 5 themes for how the learning environment can enhance meaning in daily work: (1) more time at the bedside, engaged in direct patient care, dialogue with patients and families, and bedside clinical teaching; (2) a shared sense of teamwork and respect among multidisciplinary health professionals and trainees; (3) decreasing the time spent on nonclinical and administrative responsibilities; (4) a supportive, collegial work environment; and (5) a learning environment conducive to developing clinical mastery and progressive autonomy. Participants identified actions to achieve these goals.

Conclusions

A national, multispecialty group of trainees developed actionable recommendations for how clinical learning environments can be improved to combat physician burnout by fostering meaning in work. These improvements can be championed by trainees.
Incidence of Patient Identification Errors observed before Medication and Procedure/Intervention
Authors: Kaushik Saakshi , Chawla, Ritwik
Published: March 2017

Objectives

To identify the number of individuals for whom double identification check was done before administering medication and before procedure/intervention, as per Continual Quality Improvement 3j indicator of National Accreditation Board of Hospitals (4th edition) and hospital policy.

Materials and methods

The study was a concurrent, observational recording of the study population which included doctors/surgeons, nurses, and/or technicians before administration of any medication and before beginning of any procedure/intervention. The observations were recorded on a prepared checklist to find the compliance of incidence of patients’ double identification.

Results

A total of 34 observations were recorded before administering medication to a patient. In 18 cases, wristbands were not being used, and identification details were incorrect in 4 cases. Of 34 cases, identifiers were illegible in 6 cases. The major area where the error was high was noncompliance to verbal confirmation of identity (ID) and checking it from the patient’s file. Out of 34 observations before a procedure/intervention, 9 errors were identified in cases where the ID band was not used for verification, and identification details on the band were illegible in 5 cases. In six cases, the patient’s name was not verbally confirmed with the patient or carer. Furthermore, in 10 cases, verbally confirmed name was not checked with the patient’s file. Out of 34 cases, double identification was not done in 13 cases.

Conclusion

Many nurses, doctors, and technicians in clinical settings do not verify patient ID before performing a task, resulting in more than one-third of staff not conforming themselves with the double identification procedure. The study also showed that over three-fourths of the total invasive procedures are compliant to double identification. On the contrary, noninvasive procedures showed less than one-fourth compliance to double identification.

‘Mensen genoeg die voor vos, varken of lam worden uitgemaakt. Maar omgekeerd?’
Authors: Fraipont Barbara
Published: March 2017

‘People enough that are called fox, pig or lamb. But the other way round?’: a zoopoetical comparison between Charlotte Mutsaers' and La Fontaine’s animal texts

This article aims to highlight the yet unexplored zoopoetical relation of the Dutch writer and artist Charlotte Mutsaers (1942-) to the famous animal fables of Jean de la Fontaine. A couple of important animal configurations will be identified in Mutsaers’s work through the analysis of animal discursive devices and metamorphoses in La Fontaine. In this respect, La Fontaine’s fable ‘La Chatte métamorphosée en femme’ (‘The cat metamorphosed into a woman’) (1688-1693) will be compared with Mutsaers’s novel Koetsier Herfst (2008). The literary-philosophical frameworks of metamorphosis and hybridity as well as the becoming-animal motif, drawn from research in the Cultural and Literary Animal Studies (CLAS), will prove useful to show how animal aspects in Mutsaers and La Fontaine relate to each other and correlate with different political discourses about the animal. The analysed creative and discursive human-animal patterns in Mutsaers’s and La Fontaine’s texts set out significant social-philosophical reversals of perspective about the animal-human bond and shed new light on Mutsaers’s artistic practice.
In de demonische schaduw van de grote meester
Authors: Van Rompaey Andreas
Published: March 2017

In 1979, the Dutch author Louis Ferron published the novel De gallische ziekte, a literary work that often is linked to postmodernism. The nineteenth century tale ‘Der Sandmann’ by E.T.A. Hoffmann serves as one of the narrative’s many intertexts. In this article, I will examine whether the same cultural templates show up in both ‘Der Sandmann’ and De gallische ziekte. Although De gallische ziekte does include more or less the same cultural templates as ‘Der Sandmann’, my research also shows in which way Ferron adapts those templates to suit his own worldview.
Impact of vertical wind shear on roll structure in idealized hurricane boundary layers
Authors: Wang Shouping , Jiang Qingfang
Published: March 2017

Abstract. Quasi-two-dimensional roll vortices are frequently observed in hurricane boundary layers. It is believed that this highly coherent structure, likely caused by the inflection-point instability, plays an important role in organizing turbulent transport. Large-eddy simulations are conducted to investigate the impact of wind shear characteristics, such as the shear strength and inflection-point level, on the roll structure in terms of its spectral characteristics and turbulence organization. A mean wind nudging approach is used in the simulations to maintain the specified mean wind shear without directly affecting turbulent motions. Enhancing the radial wind shear expands the roll horizontal scale and strengthens the roll's kinetic energy. Increasing the inflection-point level tends to produce a narrow and sharp peak in the power spectrum at the wavelength consistent with the roll spacing indicated by the instantaneous turbulent fields. The spectral tangential momentum flux, in particular, reaches a strong peak value at the roll wavelength. In contrast, the spectral radial momentum flux obtains its maximum at the wavelength that is usually shorter than the roll's, suggesting that the roll radial momentum transport is less efficient than the tangential because of the quasi-two-dimensionality of the roll structure. The most robust rolls are produced in a simulation with the highest inflection-point level and relatively strong radial wind shear. Based on the spectral analysis, the roll-scale contribution to the turbulent momentum flux can reach 40 % in the middle of the boundary layer.
Combined retrieval of Arctic liquid water cloud and surface snow properties using airborne spectral solar remote sensing
Authors: Ehrlich André , Bierwirth Eike , Istomina Larysa , Wendisch Manfred
Published: March 2017

Abstract. In the Arctic, the passive solar remote sensing of cloud properties over highly reflecting ground is challenging due to the low contrast between the clouds and underlying surfaces (sea ice and snow). Uncertainties in retrieved cloud optical thickness τ and cloud droplet effective radius reff,C may arise from uncertainties in the assumed spectral surface albedo, which is mainly determined by the commonly unknown snow effective grain size reff,S. Therefore, in a first step this snow grain size effect is quantified systematically for a conventional bi-spectral retrieval of τ and reff,C for liquid water clouds. The largest impact of reff,S of up to 83 % on τ and 62 % on reff,C was found in case of small reff,S and optically thin clouds. In the second part of the paper a retrieval method is presented that simultaneously retrieves all three parameters (τ, reff,C, reff,S) in order to account for changes of the snow grain size in the cloud retrieval algorithm. Spectral cloud reflectivities at the three wavelength λ1 = 1040 nm (sensitive to reff,S), λ2 = 1650 nm (sensitive to τ), and λ3 = 2100 nm (sensitive to reff,C) were normalized to reflectivity ratios and combined in a tri-spectral retrieval algorithm. Measurements collected by the Spectral Modular Airborne Radiation measurement sysTem (SMART-Albedometer) during the research campaign Vertical Distribution of Ice in Arctic Mixed-Phase Clouds (VERDI, April/May 2012) were used to test the retrieval procedure. Two cases of observations above the Canadian Beaufort Sea, one with dense snow-covered sea ice and another with a distinct sea ice edge were analyzed. The retrieved values of τ, reff,C, and reff,S consistently represented the cloud properties across this transition from snow-covered sea ice to the open water and were comparable to estimates based on satellite data. Analysis showed, that the uncertainties of the tri-spectral retrieval increase for high τ, and low reff,S, but nevertheless allows a simultaneous retrieval of cloud and surface snow properties providing snow effective grain size estimates in cloud-covered areas.
Spatio-seasonal variability of chromophoric dissolved organic matter absorption and responses to photobleaching in a large shallow temperate lake

Published: March 2017

Abstract. The development and validation of remote-sensing-based approaches for the retrieval of chromophoric dissolved organic matter (CDOM) concentrations requires a comprehensive understanding of the sources and magnitude of variability in the optical properties of dissolved material within lakes. In this study, spatial and seasonal variability in concentration and composition of CDOM and the origin of its variation was studied in Lake Balaton (Hungary), a large temperate shallow lake in central Europe. In addition, we investigated the effect of photobleaching on the optical properties of CDOM through in-lake incubation experiments. There was marked variability throughout the year in CDOM absorption in Lake Balaton (aCDOM(440) = 0. 06–9.01 m−1). The highest values were consistently observed at the mouth of the main inflow (Zala River), which drains humic-rich material from the adjoining Kis-Balaton wetland, but CDOM absorption decreased rapidly towards the east where it was consistently lower and less variable than in the westernmost lake basins. The spectral slope parameter for the interval of 350–500 nm (SCDOM(350–500)) was more variable with increasing distance from the inflow (observed range 0.0161–0.0181 nm−1 for the mouth of the main inflow and 0.0158–0.0300 nm−1 for waters closer to the outflow). However, spatial variation in SCDOM was more constant exhibiting a negative correlation with aCDOM(440). Dissolved organic carbon (DOC) was strongly positively correlated with aCDOM(440) and followed a similar seasonal trend but it demonstrated more variability than either aCDOM or SCDOM with distance through the system. Photobleaching resulting from a 7-day exposure to natural solar UV radiation resulted in a marked decrease in allochthonous CDOM absorption (7.04 to 3.36 m−1, 42 % decrease). Photodegradation also resulted in an increase in the spectral slope coefficient of dissolved material.
Reconstructing Late Holocene North Atlantic atmospheric circulation changes using functional paleoclimate networks

Published: March 2017

Abstract. Obtaining reliable reconstructions of long-term atmospheric circulation changes in the North Atlantic region presents a persistent challenge to contemporary paleoclimate research, which has been addressed by a multitude of recent studies. In order to contribute a novel methodological aspect to this active field, we apply here evolving functional network analysis, a recently developed tool for studying temporal changes of the spatial co-variability structure of the Earth's climate system, to a set of Late Holocene paleoclimate proxy records covering the last two millenia. The emerging patterns obtained by our analysis are intimately related to long-term changes in the dominant mode of atmospheric circulation in the region, the North Atlantic Oscillation (NAO). By comparing the time-dependent inter-regional linkage structures of the obtained functional paleoclimate network representations to a recent multi-centennial NAO reconstruction, we identify strong co-variability between Southern Greenland, Svalbard and Fennoscandia as being indicative of a positive NAO phase, while connections from Greenland and Fennoscandia to Central Europe are more pronounced during negative NAO phases. By drawing upon this correspondence, we use some key parameters of the evolving network structure to obtain a qualitative reconstruction of the NAO long-term variability over the entire Common Era (last 2000 years) using a linear regression model trained upon the existing shorter reconstruction.

Abstract. Daily evapotranspiration is a major component of water resources management plans. In arid ecosystems, the quest for an efficient water budget is always hard to achieve due to insufficient irrigational water and high evapotranspiration rates. Therefore, monitoring of daily evapotranspiration is a key practice for sustainable water resources management, especially in arid environments. Remote sensing techniques offered a great help to estimate the daily evapotranspiration on a regional scale. Existing open-source algorithms proved to estimate daily evapotranspiration comprehensively in arid environments. The only deficiency of these algorithms is the course scale of the used remote sensing data. Consequently, the adequate downscaling algorithm is a compulsory step to rationalize an effective water resources management plan. Daily evapotranspiration was estimated fairly well using an Advance Along-Track Scanner Radiometer (AATSR) in conjunction with (MEdium Resolution Imaging Spectrometer) MERIS data acquired in July 2013 with 1 km spatial resolution and 3 days of temporal resolution under a surface energy balance system (SEBS) model. Results were validated against reference evapotranspiration ground truth values using standardized Penman–Monteith method with R2 of 0.879. The findings of the current research successfully monitor turbulent heat fluxes values estimated from AATSR and MERIS data with a temporal resolution of 3 days only in conjunction with reliable meteorological data. Research verdicts are necessary inputs for a well-informed decision-making processes regarding sustainable water resource management.

Abstract. Atmospheric pressure gradients and pressure fluctuations drive within-snow air movement that enhances gas mobility through interstitial pore space. The magnitude of this enhancement in relation to snow microstructure properties cannot be well predicted with current methods or validated relationships. In a set of field experiments we injected a dilute mixture of 1 % carbon monoxide and nitrogen gas of known volume into the topmost layer of a snowpack and, using a distributed array of thin film sensors, measured plume evolution as a function of wind forcing. We found enhanced dispersion in the streamwise direction and also along low resistance pathways in the presence of wind. These results suggest that atmospheric constituents contained in snow can be anisotropically mixed depending on the wind environment and snow structure, having implications for surface snow reaction rates and interpretation of firn and ice cores.
PROPRIEDADES DE ARGAMASSAS COM EVA (ETHYLENE VINYL ACETATE) EM SUBSTITUIÇÃO PARCIAL AO AGREGADO

Published: March 2017

RESUMO: O setor da construção civil apresenta grande potencial para aproveitamento de vários tipos de resíduos industriais. A incorporação dos resíduos, principalmente nas argamassas e concretos, produtos com vasta aplicabilidade no setor, tem se mostrado como uma ótima alternativa na diversificação das matérias-primas e para a economia de recursos naturais. Esse trabalho avaliou as propriedades das argamassas, no estado fresco e endurecido, produzidas com substituição parcial da areia por resíduo de EVA (Ethylene Vinyl Acetate). Para isso, foram preparadas argamassas com teores de substituição do agregado 0% (referência), 5%, 10% e 15%, em massa. A relação água/cimento, para cada traço, foi determinada empiricamente e mantida constante para as argamassas com substituição. Os resultados apontam que as argamassas produzidas com agregado de EVA apresentam menor absorção de água e também um decréscimo da resistência mecânica. Desta forma, a produção de argamassas utilizando EVA em substituição ao agregado natural é viável, todavia é necessário avaliar os parâmetros mínimos de aplicação para cada finalidade. Dessa forma, o trabalho apresenta contribuição ao servir de suporte a gestores de empresas de argamassas ou gestores de obra a tomarem decisões acerca da inserção do resíduo de EVA na produção de argamassa.

ABSTRACT: The construction sector has great potential for use of various types of industrial waste. The incorporation of waste, especially in mortar and concrete products with wide applicability in the industry, has proven to be a great alternative for diversification of raw materials and the economy of natural resources. This study evaluated the properties of mortars in fresh and hardened state, made with partial replacement of sand by waste EVA (Ethylene Vinyl Acetate). For this, mortars were prepared with substitution aggregate content 0%(reference), 5%, 10% and 15% by weight. The water / cement ratio for each trace has been empirically determined and maintained constant for the mortars with replacement. The results show that the mortars produced with EVA aggregate have lower water absorption and also a decrease in the mechanical strength. Thus, the production of mortar using EVA instead of natural aggregate is feasible, however, it is necessary to evaluate the minimum parameters for each application purpose. Thus, the work presents contribution to provide support for the mortar company managers or project managers make decisions about the insertion of EVA residue in the production of mortar.
APLICAÇÃO DE GEOTECNOLOGIAS NO MONITORAMENTO DE PROJETOS DE RECOMPOSIÇÃO DE RESERVA LEGAL

A obrigatoriedade do proprietário rural em recompor a área de reserva legal foi instituída pela Lei nº 8.171, de 17 de janeiro de 1991 e reiterada pela Medida Provisória nº 2166-67, de 24 de agosto de 2001. No âmbito estadual, esta exigência manifesta-se através do Decreto nº 11.700, de 8 de outubro de 2004 - que instituiu o Sistema de Recomposição, Regeneração e Compensação da Reserva Legal - e do Decreto n° 12.528, de 27 de março de 2008 - que instituiu o Sistema de Reserva Legal no Estado de Mato Grosso e modificou o quantitativo mínimo de recomposição anual para pelo menos um doze avos da área total necessária à complementação da referida reserva. Diante da crescente preocupação com este tema, a existência de uma metodologia de monitoramento de projetos de recomposição de reserva legal é fundamental, e o uso do geoprocessamento por possibilitar a reunião de grande número de informações em curto espaço de tempo é promissor para que se alcance tal objetivo. Este estudo avaliou o andamento da recomposição de reservas legais em três propriedades rurais do Estado de Mato Grosso do Sul utilizando geotecnologias, concluindo que não houve a recomposição proposta nos respectivos projetos devido à: falta de isolamento das áreas propostas para regeneração; plantio de espécies exóticas nas áreas destinadas à regeneração; e ao aproveitamento das áreas então propostas para recomposição como áreas de pastagem.

A nuança primordial no que se refere à qualidade e suficiência dos recursos hídricos para o abastecimento humano é a proteção, manutenção e promoção da saúde em suas variadas dimensões. Neste contexto, considera-se que o município que não dispõe de sistemas de abastecimento de água regular e de qualidade, apresenta uma maior vulnerabilidade a condições de risco a saúde. Assim, o objetivo deste trabalho foi analisar a incidência e prevalência de doenças por meio de veiculação hídrica com as condições de abastecimento e armazenamento da água no município de Massaranduba/PB. Para viabilizar a pesquisa, considerando os aspectos teóricos e práticos da realidade, optou-se pelos seguintes procedimentos: a) delimitação da área de estudo; b) trabalho de campo e c) obtenção dos resultados. Constatou-se que as formas específicas de abastecimento (açude; chuva; poço; compra) e armazenamento (caixa de água; cisterna; tonel) no Município remete a uma situação epidemiológica agravante no que tange a proliferação das doenças de veiculação hídrica, principalmente, as diarréicas e a dengue. Neste viés observou-se o reconhecimento desta conjuntura por parte da população local, uma vez que sofrem reflexos na saúde decorrente desta condição socioambiental de vulnerabilidade e risco. Portanto, as doenças de veiculação hídrica apresentaram relações com as condições de abastecimento e armazenamento da água no contexto investigado.

Published: March 2017

ResumoA alienação e o pensamento fetichizado podem retirar do ser humano a capacidade de sonhar, de ter utopia, principalmente por não identificar a aparência fenomênica da sua essência. Indistinção como essa obstaculiza compreender a gênese da questão ambiental como conseqüência inexorável do avanço capitalista. Por isso uma das questões que será debatida nesse texto consiste em refletir sobre o seguinte questionamento: até que ponto a questão ambiental é conseqüência do avanço do modo de produção capitalista? Esse debate está presente na primeira parte desse texto entendendo a questão ambiental como questão política. Na segunda parte estão reunidas diversas análises as quais visam compreender o engendramento da cultura burguesa como componente indispensável do modo de produção capitalista. E, na terceira parte, procura traçar pontos de contato entre a epistemologia ambiental e a teoria lukacsiana visando demonstrar a insustentável racionalidade da economia de mercado que é impulsionada pelo pensamento fetichizado e que será superado na medida em que se construir uma epistemologia ambiental concebendo os impactos ambientais como conseqüência do avanço capitalista. Conclui-se, portanto, a urgente tarefa de fazer emergir a epistemologia ambiental problematizando a histórica e insustentável racionalidade de mercado, bem como incorporá-la ao debate sobre o desenvolvimento elegendo novos modelos interpretativos.Palavras-chave: questão ambiental; pensamento fetichizado; avanço capitalista

Authors: Gerencsez Geraldino Carlos Francisco
Published: March 2017

Este artigo tem como objetivo expor sinteticamente o entendimento do conceito de meio vinculado ao fenômeno técnico proposto pelo geógrafo brasileiro Milton Santos. Para isso, primeiro se discute o conteúdo que propôs aos conceitos de meio, técnica, natureza e espaço, procurando entrever suas relações. Depois, se apresenta sua proposta gradual de análise da transformação do meio natural em meio técnico-científico e informacional, pontuando os recortes conceituais utilizados em cada etapa do processo de artificialização do entorno. Para, por fim, demonstrar como os conteúdos técnicos agregados ao meio geográfico podem fazê-lo revelar-se como um atuante ente social; legitimando, dessa maneira, a análise geográfica como uma das principais vias de compreensão das relações sociais contemporâneas.
