Tourists' Evaluation of Climate Change Risks in the Canary Islands: A Heterogeneous Response Modelling Approach
Authors: León Carmelo J. , Araña Jorge E. , González Matías , de León Javier
Published: August 2014

This paper compares the differences between the monetary measures of willingness to accept and willingness to pay (WTP) for changes in climate change risk. The empirical evidence comes from tourists in the Canary Islands. The modelling approach utilizes a Bayesian mixture of normal distribution model that allows the authors to consider heterogeneity across both WTP and willingness to accept (WTA) question formats. The results show that the WTP for lower risks is lower than the WTA higher risks, and that the disparity between these measures depends on the market segments, the specific climate change risk and the characteristics of the individuals.

Governança territorial em zonas costeiras protegidas: uma avaliação exploratória da experiência catarinense
Authors: Vivacqua Melissa , Santos Cláudia Regina dos , Vieira Paulo Freire
Published: August 2014

O artigo oferece subsídios para o debate acadêmico sobre a viabilidade de estratégias alternativas de desenvolvimento em zonas costeiras protegidas, no atual cenário de globalização assimétrica. A linha de argumentação coloca em primeiro plano a perspectiva de aplicação do conceito de desenvolvimento ter-ritorial sustentável ao processo em curso de criação de um sistema de gestão integrada e participativa do litoral catarinense. Na primeira parte, apresentamos uma visão panorâmica do processo de normatização dos instrumentos utilizados no Sistema de Gestão de Unidades de Conservação no Brasil (SNUC). Além disso, oferecemos uma síntese do processo de construção do projeto de Gestão Integrada das Unidades de Conservação Marinho-Costeiras do Estado de Santa Catarina (GIUC-SC). Em seguida, exploramos o potencial contido na abordagem territorial do desenvolvimento para a consolidação do processo de integração do SNUC ao Plano Nacional de Gerenciamento Costeiro. No final do texto justificamos a necessidade de investimentos mais substanciais em pesquisas de corte ecológico-político sobre mediação de conflitos socioambientais e promoção de sistemas de governança territorial nessas áreas.
Povos e Desenvolvimento: outros saberes e outros modelos modelos para alcançar a sustentabilidade
Authors: Gotta Claudia Andrea , Taruselli María Victoria
Published: August 2014

O presente artigo realiza uma reflexão sobre a noção de desenvolvimento com base em um marco analítico que, partindo da diversidade cultural latino-americana, resgata uma multiciplidade de critérios os quais transcendem o limitado olhar das análises econômicas. Nessa direção, focaliza os saberes dos povos nativos da América, cujas cosmovisões e formas culturais de vida permitem pensar em modelos alternativos baseados em critérios de sustentabilidade e equidade ecológica. Enquanto a imposição e reprodução de uma única forma de entender o desenvolvimento, associada à produção ao crescimento e ao consumo, negaram outras cosmovisões e modos de vida e legitimaram a implementação de políticas de silenciamento, exclusão e extermínio de povos originários, estes mantiveram uma relação harmônica com a natureza, resistindo mediante a sustentabilidade de uma economia de não-acumulação, fundada em princípios de distribuição e equidade. A dimensão total da vida, o ambiente e o mundo, e a conse-quente luta histórica e cotidiana dos povos para preservar a diversidade biológica e cultural e as relações sociais comunitárias, construíram, de forma natural, a cultura da sustentabilidade. Em nossa perspectiva, é imprescindível recuperar essas cosmovisões em tempos em que se demonstrou que a imposição de uma única forma de ler e gerir o desenvolvimento e, em um sentido mais geral, o mundo, levou, e ainda leva, a desastrosas consequências ambientais em suas diversas dimensões, a saber, ecológica, econômica, sociocultural e política.
Natureza e sociedade: a controvérsia sobre os alicerces da conduta humana
Authors: HEEMANN Ademar
Published: August 2014

Esta reflexão procura contribuir para o entendimento das dimensões epistemológica e ética que circundam a questão ambiental e, de um modo mais específico, as reivindicações dos movimentos de amor à natureza. Para tanto, argumenta-se sobre a necessidade de uma compreensão da demarche que procura extrair da ordem natural os indicativos para a conduta humana. Essa é mais uma invenção grega, daí porque são revisitadas as rupturas com o mundo mítico e religioso. Com essa intenção é construída uma problemática em face das visões fundacionista e relativista da legitimação ética. Abstract This reflection aims at contributing to the understanding of both the epistemological and the ethical dimension that encircle the environmental issue, and , more specifically, the demands from the movements that love nature. For this reason, it debates about the need to an understanding of the demarche that tries to extract from the natural order the clues for the human conduct. This is another Greek invention and that is why the ruptures with the mythical world are reviewed. It is bearing this intention that a question is posed according to the both the Foundationist and Relativist vision of ethical legitimization.
El concepto de desarrollo sustentable treinta años después
Authors: FOLADORI Guillermo , TOMMASINO Humberto
Published: August 2014

Neste artigo fazemos uma análise da evolução do conceito de desenvolvimento sustentável nos últimos trinta anos. Nosso principal argumento é que existem três eixos a partir dos quais podem-se agrupar os diferentes enfoques. O primeiro restringe o conceito de desenvolvimento sustentável à sustentabilidade ecológica. O segundo, soma à sustentabilidade ecológica uma social, mas somente como ponte para a análise da sustentabilidade ecológica. Um terceiro eixo considera o desenvolvimento sustentável como a coevolução da sustentabilidade ecológica e social.
O desenvolvimento da ecologia no Brasil
Authors: MARTINS Rogério Parentoni , LIMA Carlos Araújo
Published: August 2014

Para o desenvolvimento da ecologia no país é necessário considerar quatro problemas fundamentais: 1. A restrita contribuição dos ecólogos brasileiros para desenvolvimento teórico da ecologia; 2. As dificuldades que os integrantes dos programas de pós-graduação têm em reconhecer a identidade intelectual da ecologia e desenhar os contornos que definem sua abrangência; 3. Envolvimento de profissionais sem formação ecológica específica, por exemplo, engenheiros sanitários, agrônomos e florestais, arquitetos, sociólogos e pedagogos em práticas ambientais, muitas vezes exercendo atividades no âmbito da competência de ecólogos, mas ignorando conhecimentos ecológicos fundamentais para as soluções que propõem; 4. Por isso mesmo, os ecólogos devem entender não só a necessidade de uma abordagem interdisciplinar dos problemas ambientais, mas também identificar e diferenciar o papel efetivo da teoria ecológica na construção e aplicação do conhecimento interdisciplinar. Abstract Four shortcomings prevent the improvement of ecology in Brazil: 1. Brazilian ecologists are not contributing significativelly to theoretical ecology; 2. Members and students of gratuate programs in ecology have difficulties to recognize the identity of ecology; 3. Non-ecologists working on environmental problems lack fundamental knowledge in ecology; 4. Ecologists do not recognize interdisciplinarity as essencial to solve environmental problems.
Flow resistance equations for mountain rivers
Authors: López Alonso R. , Barragán Fernández J. , Colomer Cugat M. A.
Published: August 2014

Three models of flow resistance (a Keulegan-type logarithmic law and two models developed for large-scale roughness conditions: the full logarithmic law and a model based on an inflectional velocity profile) were calibrated, validated and compared using an extensive database (N = 1,533) from rivers and flumes, representative of a wide hydraulic and geomorphologic range in the field of gravel-bed and mountain channels. It is preferable to apply the model based on an inflectional velocity profile in the relative submergence (y/d90) interval between 0.5 and 15, while the full logarithmic law is preferable for values below 0.5. For high relative submergence, above 15, either the logarithmic law or the full logarithmic law can be applied. The models fitted to the coarser percentiles are preferable to those fitted to the median diameter, owing to the higher explanatory power achieved by setting a model, the smaller difference in the goodness-of-fit between the different models and the lower influence of the origin of the data (river or flume).
Basic wood density of Acacia melanoxylon R.Br related to sample tree height, tree and site
Authors: Igartúa Dora D. V. , Monteoliva S.
Published: August 2014

The aim of the work was to assess basic wood density variations of Acacia melanoxylon R.Br according to sample tree height, tree, and site. Twenty trees were selected from four sites in Buenos Aires Province, Argentine. Wood density was determined over two disc samples at four tree height (base, breast height, 30% and 50% of total tree height). According to determined ages, some trees were divided into two groups according to age (26-32 years and 9-12 years) and data were analyzed with an analysis of variance according to mixed model where tree was the random effecTrees represent 74 % of total random variance. Within tree, axial tendency of wood density was to decrease from the base toward breast height and then its value was stable to the top. This was consistent across all sites and age groups. Forest resource growing at Los Tuelches site presented the highest basic wood density.
Effects of Buffalo and Cow Milk Mixtures Enriched With Sodium Caseinates on the Physicochemical, Rheological and Sensory Properties of a Stirred Yogurt Product
Authors: Petridis Dimitris , Dimitreli Georgia , Vlahvei Kalliopi , Deligeorgakis Christodoulos
Published: August 2014

The physicochemical, rheological and sensory (objective and hedonic) properties of stirred yogurt made from buffalo and cow milk mixtures enriched with Sodium Caseinates (SCN) were evaluated. Five different milk mixtures (buffalo:cow; 0:100, 25:75, 50:50, 75:25, 100:0) with or without the addition of 1% SCN were fermented so as to produce 10 different yogurt samples. According to the results, SCN addition increased the brightness (L*), the elastic behavior, the viscosity (instrumental and sensory) and the flow behavior index (n), while it reduced the yellow color intensity (b*) of yogurt samples. Addition of milk affected significantly all the instrumental variables apart from the green color intensity (a*) and so happened but sparsely with the interactive effects between milk mixture and SCN addition. Redundancy analysis was proved a successful tool to elucidate the complex physicochemical, rheological and sensory profile of the stirred yogurt samples. Loss tanget (tan ?) and b* were indicative for high cow milk concentrations and the rest of attributes fashion with high buffalo milk concentrations, apart from n which favored samples with high cow milk enrichment and SCN addition. Panelists prefered adequately a stirred yogurt rich in buffalo milk concentration (75-100%) and low in cow milk (0-25%), enriched with SCN, with texture perceived as adequate fatty and viscous.
Flood forecasting for River Mekong with data‐based models
Authors: Shahzad Khurram M. , Plate Erich J.
Published: August 2014

In many regions of the world, the task of flood forecasting is made difficult because only a limited database is available for generating a suitable forecast model. This paper demonstrates that in such cases parsimonious data‐based hydrological models for flood forecasting can be developed if the special conditions of climate and topography are used to advantage. As an example, the middle reach of River Mekong in South East Asia is considered, where a database of discharges from seven gaging stations on the river and 31 rainfall stations on the subcatchments between gaging stations is available for model calibration. Special conditions existing for River Mekong are identified and used in developing first a network connecting all discharge gages and then models for forecasting discharge increments between gaging stations. Our final forecast model (Model 3) is a linear combination of two structurally different basic models: a model (Model 1) using linear regressions for forecasting discharge increments, and a model (Model 2) using rainfall‐runoff models. Although the model based on linear regressions works reasonably well for short times, better results are obtained with rainfall‐runoff modeling. However, forecast accuracy of Model 2 is limited by the quality of rainfall forecasts. For best results, both models are combined by taking weighted averages to form Model 3. Model quality is assessed by means of both persistence index PI and standard deviation of forecast error.
Integrating weather and climate prediction: Toward seamless hydrologic forecasting
Authors: Yuan Xing , Wood Eric F. , Liang Miaoling
Published: August 2014

Seamless hydrologic forecasting is explored through integrating medium‐range weather forecasts from NOAA's Global Ensemble Forecast System Reforecast version 2 (GEFSRv2) and seasonal climate predictions from the Climate Forecast System version 2 (CFSv2). A set of 25 year hydrologic reforecasts over the Ohio basin shows that incorporating GEFSRv2 14 day forecasts into the Ensemble Streamflow Prediction (ESP) and CFSv2‐based seasonal forecast systems improves efficiency scores for month‐1 streamflow by up to 32.6% and 11.2%, respectively. For the second biweekly forecast, the combination of GEFSRv2 and CFSv2 is superior to that of GEFSRv2 and ESP by increasing efficiency score up to 17.2%, suggesting that the climate prediction usefully extends the medium‐range hydrologic forecast. As compared with ESP, incorporation of either weather or climate prediction improves the month‐1 soil moisture drought prediction significantly. The potential of seamless hydrologic forecast should be further investigated from the operational service perspective and improved understanding of underlying physical processes.
Catalytic Borylation of SCF3‐Functionalized Arenes by Rhodium(I) Boryl Complexes: Regioselective CH Activation at the ortho‐Position
Authors: Kalläne Sabrina I. , Braun Thomas
Published: August 2014

An unprecedented reaction pathway for the borylation of SCF3‐containing arenes using [Rh(Bpin)(PEt3)3] (pin=pinacolato) is reported. Catalytic processes were developed and the functionalizations proceed under mild reaction conditions. The CH activations occur with a unique regioselectivity for the position ortho to the SCF3 group, which apparently serves as directing group. Borylated SCF3 compounds can serve as versatile building blocks.
A high‐throughput adrenaline test for the exploration of the catalytic potential of halohydrin dehalogenases in epoxide ring‐opening reactions
Authors: Tang Lixia , Liu Yu , Jiang Rongxiang , Zheng Yu , Zheng Kai , Zheng Huayu
Published: August 2014

The principle of the adrenaline test for enzymes is based on the quantification of periodate‐sensitive reaction products with adrenaline to produce a chromogenic compound adrenochrome that can be easily detected. Here, a rapid whole‐cell ‐based adrenaline assay for the activity measurement of halohydrin dehalogenases (HHDHs) in nucleophile‐mediated epoxide ring‐opening reactions is presented. The assay was validated using two types of model reactions (glycidol with nucleophiles and nitrite with epoxides). Moreover, the reliability of the assay was confirmed by gas chromatography analysis. Our results demonstrated that the developed assay is efficient in both library screening and the evaluation of catalytic diversity and specificity of HHDHs. Thus, the assay represents a valuable tool in the evolution of HHDHs for its industrial applications. Moreover, the adrenaline test exhibits a great potential for enzyme assay and could be easily adopted for other suitable enzymes.
Phosphorylation of silk fibroins improves the cytocompatibility of silk fibroin derived materials: A platform for the production of tuneable material
Authors: Volkov Vadim , Vasconcelos Andreia , Sárria Marisa P. , Gomes Andreia C. , Cavaco‐Paulo Artur
Published: August 2014

Silk fibroin demonstrates great biocompatibility and is suitable for many biomedical applications, including tissue engineering and regenerative medicine. Current research focuses on manipulating the physico‐chemical properties of fibroin, and examining the effect of this manipulation on firobin's biocompatibility. Regenerated silk fibroin was modified by in vitro enzymatic phosphorylation and cast into films. Films were produced by blending, at several ratios, the phosphorylated and un‐phosphorylated fibroin solutions. Fourier transform infra‐red spectroscopy was used to determine the specific P–OH vibration peak, confirming the phosphorylation of the regenerated silk fibroin solution. Differential scanning calorimetry showed that phosphorylation altered the intra‐ and inter‐molecular interactions. Further experiments demonstrated that phosphorylation can be used to tailor the hydrophylicity/hydrophobicity ratio as well as the crystalinity of silk fibroin films. Release profiling of a model drug was highly dependent on silk modification level. Cytotoxicity assays showed that exposure to lixiviates of phosphorylated films only slightly affected cellular metabolism and proliferation, although direct contact resulted in a strong direct correlation between phosphorylation level and cell proliferation. This new method for tuning silk biomaterials to obtain specific structural and biochemical features can be adapted for a wide range of applications. Phosphorylation of silk fibroins may be applied to improve the cytocompatibility of any silk‐based device that is considered to be in contact with live animals or human tissues.

Enantiomer Distribution of Major Chiral Volatile Organic Compounds in Selected Types of Herbal Honeys
Authors: Pažitná Alexandra , Džúrová Jana , Špánik Ivan
Published: August 2014

In this article, volatile organic compounds in 14 honey samples (rosemary, eucalyptus, orange, thyme, sage, and lavender) were identified. Volatile organic compounds were extracted using a solid phase microextraction method followed by gas chromatography connected with mass spectrometry analysis. The studied honey samples were compared based on their volatile organic compounds composition. In total, more than 180 compounds were detected in the studied samples. The detected compounds belong to various chemical classes such as terpenes, alcohols, acids, aldehydes, ketones, esters, norisoprenoids, benzene and furane derivatives, and organic compounds containing sulfur and nitrogen heteroatom. Ten chiral compounds (linalool, trans‐linalool oxide, cis‐linalool oxide, 4‐terpineol, α‐terpineol, hotrienol, and four stereoisomers of lilac aldehydes) were selected for further chiral separation.

Calculating core‐level excitations and x‐ray absorption spectra of medium‐sized closed‐shell molecules with the algebraic‐diagrammatic construction scheme for the polarization propagator
Authors: Wenzel Jan , Wormit Michael , Dreuw Andreas
Published: August 2014

Core‐level excitations are generated by absorption of high‐energy radiation such as X‐rays. To describe these energetically high‐lying excited states theoretically, we have implemented a variant of the algebraic‐diagrammatic construction scheme of second‐order ADC(2) by applying the core‐valence separation (CVS) approximation to the ADC(2) working equations. Besides excitation energies, the CVS‐ADC(2) method also provides access to properties of core‐excited states, thereby allowing for the calculation of X‐ray absorption spectra. To demonstrate the potential of our implementation of CVS‐ADC(2), we have chosen medium‐sized molecules as examples that have either biological importance or find application in organic electronics. The calculated results of CVS‐ADC(2) are compared with standard TD‐DFT/B3LYP values and experimental data. In particular, the extended variant, CVS‐ADC(2)‐x, provides the most accurate results, and the agreement between the calculated values and experiment is remarkable. © 2014 Wiley Periodicals, Inc.
Arginine promotes Proteus mirabilis motility and fitness by contributing to conservation of the proton gradient and proton motive force
Authors: Armbruster Chelsie E. , Hodges Steven A. , Smith Sara N. , Alteri Christopher J. , Mobley Harry L. T.
Published: August 2014

Swarming contributes to Proteus mirabilis pathogenicity by facilitating access to the catheterized urinary tract. We previously demonstrated that 0.1–20 mmol/L arginine promotes swarming on normally nonpermissive media and that putrescine biosynthesis is required for arginine‐induced swarming. We also previously determined that arginine‐induced swarming is pH dependent, indicating that the external proton concentration is critical for arginine‐dependent effects on swarming. In this study, we utilized survival at pH 5 and motility as surrogates for measuring changes in the proton gradient (ΔpH) and proton motive force (μH+) in response to arginine. We determined that arginine primarily contributes to ΔpH (and therefore μH+) through the action of arginine decarboxylase (speA), independent of the role of this enzyme in putrescine biosynthesis. In addition to being required for motility, speA also contributed to fitness during infection. In conclusion, consumption of intracellular protons via arginine decarboxylase is one mechanism used by P. mirabilis to conserve ΔpH and μH+ for motility.
NMR of guest‐host systems: 8CB in chiral nematic porous glasses

Published: August 2014

Liquid crystals confined to porous materials often have different critical phenomena and ordering than in the bulk. Through the selection of pore size, structure and guest liquid crystal, these systems could enable a variety of functional materials for applications such as sensors and displays. A recent example of such a system is chiral nematic mesoporous films infiltrated with liquid crystal 4‐cyano‐4'‐n‐octylbiphenyl (8CB), which has reversible thermal switching of its optical bandgap. The optical bandgap is lost when the ordered 8CB guests are heated above ∼50 °C, where the 8CB becomes isotropic. In this study, we have used NMR cryoporometry and pulsed‐field gradient diffusion measurements to determine the pore sizes and structures of various chiral nematic mesoporous silica and organosilica films. Temperature and orientation‐dependent wideline 15N NMR spectra of films infiltrated with 15N‐labelled 8CB guests show that the ordering of the 8CB mesogens is consistent with an average orientation parallel to the chiral nematic pore axes. Inclusion of a large, orientation‐dependent shift was necessary to fit the spectra, probably due to susceptibility differences between the 8CB guests and the organosilica host.

Aplicación de las opciones reales en la toma de decisiones en los mercados de electricidad
Authors: Isaza Cuervo Felipe , Botero Botero Sergio
Published: August 2014

Las decisiones estratégicas en los mercados de electricidad están sujetas a un alto riesgo e incertidumbre; en consecuencia, las opciones reales aparecen como una alternativa para la toma de decisiones en dichos mercados. En el presente artículo se realiza una revisión de literatura analizando y clasificando aplicaciones de opciones reales sobre decisiones de inversión, operación, y de políticas y programas energéticos. Además se presenta un ejemplo sintético de aplicación teórico utilizando un modelo binomial para incor- porar energía eólica en vez de térmica de acuerdo con la volatilidad de los precios del carbón. Se concluye que las opciones reales permiten tomar mejores decisiones que los métodos tradicionales, pues capturan a través de sus múltiples modelos las diferentes incertidumbres propias de estos mercados.
Measurements of turbulent diffusion in uniformly sheared flow
Authors: Vanderwel Christina , Tavoularis Stavros
Published: August 2014

The diffusion of a plume of dye in uniformly sheared turbulent flow in a water tunnel was investigated using simultaneous stereoscopic particle image velocimetry (SPIV) and planar laser-induced fluorescence (PLIF). Maps of the mean concentration and the turbulent concentration fluxes in planes normal to the plume axis were constructed, from which all components of the second-order turbulent diffusivity tensor were determined for the first time. Good agreement between the corresponding apparent and true diffusivities was observed. The turbulent diffusivity tensor was found to have strong off-diagonal components, whereas the streamwise component appeared to be counter-gradient. The different terms in the advection–diffusion equation were estimated from the measurements and their relative significance was discussed. All observed phenomena were explained by physical arguments and the results were compared to previous ones.
Low-frequency vibrations of two-dimensional droplets on heterogeneous substrates
Authors: Savva Nikos , Kalliadasis Serafim
Published: August 2014

We present a theoretical investigation of the effects of low-frequency vibrations on the motion of two-dimensional droplets on heterogeneous substrates in the presence of gravity and substrate heterogeneities, both chemical and topographical. A combined analytical and numerical approach is undertaken, extending the work of Savva & Kalliadasis (J. Fluid Mech., vol. 725, 2013, pp. 462–491) on inclined heterogeneous substrates to include the effects of substrate vibrations. Via a matching procedure and under the quasi-static assumption, we obtain evolution equations for the moving fronts. These equations are then invoked in a wide variety of case studies. It is demonstrated that vertically vibrated horizontal ratcheted substrates can induce unidirectional motion. For inclined substrates, we focus on a number of qualitative aspects of the peculiar vibration-induced climbing of droplets reported in experiments by Brunet, Eggers & Deegan (Phys. Rev. Lett., vol. 99, 2007, art. 144501). We examine the effects of weak inertia on the dynamics, deduce analytical criteria for the uphill motion in the limit of weak gravitational and vibrational effects, and demonstrate that substrate heterogeneities may be utilised to enhance droplet transport.
