Published: April 2018

AbstractPhotosynthetic biocatalysts are emerging as a new class of materials, with their sophisticated and intricate structure, which promise improved remarkable quantum efficiency compared to conventional inorganic materials in artificial photosynthesis. To break the limitation of efficiency, the construction of bioconjugated photo‐electrochemical conversion devices has garnered substantial interest and stood at the frontier of the multidisciplinary research between biology and chemistry. Herein, a biohybrid photoanode of a photosynthetic membrane protein (Photosystem II (PS II)), extracted from fresh spinach entrapped on mesoporous WO3 film, is fabricated on fluorine‐doped tin oxide. The PS II membrane proteins are observed to communicate with the WO3 electrode in the absence of any soluble redox mediators and sacrificial reagents under the visible light of the solar spectrum, even to 700 nm. The biohybrid electrode undergoes electron transfer and generates a significantly enhanced photocurrent compared to previously reported PS II‐based photoanodes with carbon nanostructures or other semiconductor substrates for solar water oxidation. The maximum incident photon‐to‐current conversion efficiency reaches 15.24% at 400 nm in the visible light region. This work provides some insights and possibilities into the efficient assembly of a future solar energy conversion system based on visible‐light‐responsive semiconductors and photosynthetic proteins.

Published: April 2018

Abstract3D materials are considered promising for photocatalytic applications in air purification because of their large surface areas, controllability, and recyclability. Here, a series of aerogels consisting of graphitic‐carbon nitride (g‐C3N4) modified with a perylene imide (PI) and graphene oxide (GO) are prepared for nitric oxide (NO) removal under visible‐light irradiation. All of the photocatalysts exhibit excellent activity in NO removal because of the strong light absorption and good planarity of PI–g‐C3N4 coupled with the favorable charge transport properties of GO, which slow the recombination of electron–hole pairs. The aerogel containing thiophene displays the most efficient NO removal of the aerogel series, with a removal ratio of up to 66%. Density functional theory calculations are conducted to explain this result and recycling experiments are carried out to verify the stability and recyclability of these photocatalysts.
Colonialism and its legacies, as reflected in water, incorporating a view from Malawi
Authors: Mathur Chandana , Mulwafu Wapulumuka 
Published: April 2018

Continued, accelerating water inequalities and conflicts in the postcolonial world cannot be properly grasped without a thorough understanding of colonialism and its legacies. At the same time, water as a resource provides an immensely useful lens for understanding the intricacies and the dynamics of the colonial and postcolonial eras, in general terms, and in the particular historical instance of Malawi examined here. This essay draws on a range of literatures—social theory, political ecology, history, anthropology, sociology, geography, and so on—to demonstrate that struggles over water and other natural resources in the postcolonial world are situated within wider global structures and relationships of power. Starting with a discussion of theoretical approaches to water, the essay goes on to examine the processes of state formation in Sub‐Saharan Africa, and explore the intersectionality of the contemporary lived experience of class, gender, race, and ethnicity in this region. It ends with a consideration of social differentiation, land tenure, degradation of water resources and natural resource conflict in Malawi. Traversing across humanities and social science disciplines, this essay uses water as a means of cutting a path through world historical questions on the articulations between the global and the local in the present era.This article is categorized under:Human Water > Water GovernanceHuman Water > Water as Imagined and Represented
The spectral signature of wind turbine wake meandering: A wind tunnel and field‐scale study
Authors: Heisel Michael , Hong Jiarong , Guala Michele 
Published: April 2018

AbstractField‐scale and wind tunnel experiments were conducted in the 2Dto 6Dturbine wake region to investigate the effect of geometric and Reynolds number scaling on wake meandering. Five field deployments took place: 4 in the wake of a single 2.5‐MW wind turbine and 1 at a wind farm with numerous 2‐MW turbines. The experiments occurred under near‐neutral thermal conditions. Ground‐based lidar was used to measure wake velocities, and a vertical array of met‐mounted sonic anemometers were used to characterize inflow conditions. Laboratory tests were conducted in an atmospheric boundary layer wind tunnel for comparison with the field results. Treatment of the low‐resolution lidar measurements is discussed, including an empirical correction to velocity spectra using colocated lidar and sonic anemometer. Spectral analysis on the laboratory‐ and utility‐scale measurements confirms a meandering frequency that scales with the Strouhal numberSt = fD/Ubased on the turbine rotor diameterD. The scaling indicates the importance of the rotor‐scaled annular shear layer to the dynamics of meandering at the field scale, which is consistent with findings of previous wind tunnel and computational studies. The field and tunnel spectra also reveal a deficit in large‐scale turbulent energy, signaling a sheltering effect of the turbine, which blocks or deflects the largest flow scales of the incoming flow. Two different mechanisms for wake meandering—large scales of the incoming flow and shear instabilities at relatively smaller scales—are discussed and inferred to be related to the turbulent kinetic energy excess and deficit observed in the wake velocity spectra.
is regular-closed

Published: April 2018

For each $n\geq 2$, we investigate a family of iterated function systems which is parameterized by a common contraction ratio $s\in \mathbb{D}^{\times }\equiv \{s\in \mathbb{C}:0<|s|<1\}$ and possesses a rotational symmetry of order $n$. Let ${\mathcal{M}}_{n}$ be the locus of contraction ratio $s$ for which the corresponding self-similar set is connected. The purpose of this paper is to show that ${\mathcal{M}}_{n}$ is regular-closed, that is, $\overline{\text{int}\,{\mathcal{M}}_{n}}={\mathcal{M}}_{n}$ holds for $n\geq 4$. This gives a new result for $n=4$ and a simple geometric proof of the previously known result by Bandt and Hung [Fractal $n$-gons and their Mandelbrot sets. Nonlinearity 21 (2008), 2653–2670] for $n\geq 5$.
Small- and medium-sized enterprises (SME) growth and financing sources: Before and after the financial crisis
Authors: Serrasqueiro Zélia , Leitão João , Smallbone David 
Published: April 2018

AbstractIn this study, the empirical evidence regarding small- and medium-sized enterprises’ (SMEs) growth determinants allows us to conclude that: (1) stimulating factors are cash flow and gross domestic product; (2) restrictive factors are: debt, firm size, age of the firm and the interest rate; and (3) in the period after 2008, the financial crisis and implementation of austerity measures, in the Portuguese context, produced a negative effect on SME growth. In the period 2008–2012, that is, after the beginning of the financial crisis, cash flow had less importance, while debt was found to have a stronger negative effect on SME growth, compared with the pre-crisis period.
L'analyse des risques éthiques : une recherche exploratoire dans le domaine de la gouvernance municipale
Authors: Boisvert Yves 
Published: April 2018

RésuméCe texte présente les résultats d'une analyse thématique faite à partir des matériaux obtenus lors d'une recherche empirique exploratoire portant sur les risques éthiques dans le domaine municipal. Pour ce faire, nous avons réalisé un diagnostic des risques éthiques dans une municipalité canadienne ayant connu une crise importante au niveau de l'intégrité. La recherche empirique s'est faite de novembre 2015 à mars 2016, à partir d'entrevues semi-dirigées avec des acteurs dits stratégiques et des groupes de discussion avec des acteurs dits opérationnels.Notre recherche s'inscrit dans l'esprit d'un « retour d'expérience » (Wybo et Wassenhove, 2009). Ainsi, l'objectif de ce type recherche est de produire, via un travail de réflexivité collective, un bassin de connaissances pratiques pouvant permettre de mieux comprendre les risques éthiques présents dans un environnement particulier et de cibler les stratégies d'atténuation de ces risques.Pour faire notre analyse, nous avons croisé les résultats de notre enquête sur deux axes d'analyse : l'analyse des risques sous l'angle des trois indicateurs de notre cadre (conduites à risque, facteurs de risque et stratégies d'atténuation) et l'analyse transactionnelle par les parties prenantes. Nous présenterons les résultats de façon synthétique afin de faire ressortir la transversalité des données et leur rattachement à des situations transactionnelles particulières. Dans la section discussion, nous mettrons l'accent sur les stratégies d'atténuation des risques éthiques proposées par nos répondants afin de faire ressortir la grande différence de ces résultats par opposition aux propositions traditionnelles des experts institutionnels qui se sont penchés sur l’éthique du service public.

AbstractRice has the lowest grain protein content (GPC) among cereals. Efforts have been made to improve GPC through the modified bulk-pedigree method of selection. A total of 1780 F8recombinant lines were derived in the year 2013 from five different cross combinations involving two high-GPC landraces, namely ARC10075 and ARC10063, three high-yielding parents, namely Swarna, Naveen and IR64, and one parent, namely Sharbati, known for superior grain quality with high micronutrient content. Near-infrared spectroscopy was used to facilitate high-throughput selection for GPC. Significant selection differential, response to selection and non-significant differences between the predicted and observed response to selection for GPC and protein yield indicated the effectiveness of this selection process. This resulted in lines with high GPC, protein yield and desirable levels of amylose content. Further, based on high mean and stability for GPC and protein yield over the environments in the wet seasons of 2013, 2014 and the dry season of 2014, 12 elite lines were identified. Higher accumulation of glutelin fraction and non-significant change in prolamin/glutelin ratio in the grain suggested safe guarding of the nutritional value of rice grain protein of most of these identified lines. Since rice is the staple food of millions, the output of breeding for high GPC could have a significant role in alleviating protein malnutrition, especially in the developing world.
Typologies of loneliness, living alone and social isolation, and their associations with physical and mental health
Authors: SMITH KIMBERLEY J. , VICTOR CHRISTINA 
Published: April 2018

AbstractThe relationship between living alone, loneliness and social isolation, and how they are associated with health remain contentious. We sought to explore typologies based on shared experiences of loneliness, social isolation and living alone using Latent Class Analysis and determine how these groups may differ in terms of their physical and mental health. We used Wave 7 of the English Longitudinal Study of Ageing (N = 7,032; mean age = 67.3) and responses to the University of California, Los Angeles (UCLA) loneliness scale, household composition, participation in social/societal activities plus frequency of contact with friends, family and relatives for the Latent Class Analysis. The optimal number of groups was identified using model-fit criteria. The socio-demographic characteristics of groups and health outcomes were explored using descriptive statistics and logistic regression. We identified a six-cluster typology: Group 1, no loneliness or isolation; Group 2, moderate loneliness; Group 3, living alone; Group 4, moderate isolation; Group 5, moderate loneliness, living alone; and Group 6, high loneliness, moderate isolation (with high likelihood of living alone). Groups experiencing loneliness and/or isolation were more likely to report poorer physical and mental health even after adjusting for socio-demographic confounders, this was particularly notable for Group 6. Our results indicate that different typologies of living alone, loneliness and isolation can be identified using data-driven techniques, and can be differentiated by the number and severity of issues they experience.

Objectives:The aim of this study was to evaluate the direct costs of type 2 diabetes mellitus patients treated in a Brazilian public hospital.Methods:This was an exploratory retrospective cost-of-illness study with quantitative approach, using medical records of patients treated in a public hospital (2012–14), with at least one consultation over a period of 12 months. Data on patient's profile, exams, number of consultations, medications, hospitalizations, and comorbidities were collected. The cost per patient per year (pppy) was calculated as well as the costs related to glycated hemoglobin (HbA1c) values, using thresholds of 7 and 8 percent.Results:Data of 726 patients were collected with mean age of 62 ± 11 years (68.3 percent female). A total of 67.1 percent presented HbA1c > 7 percent and 44.9 percent > 8 percent. The median cost of diabetes was United States dollar (USD) 197 pppy. The median costs of medication were USD 152.49 pppy, while costs of exams and consultations were USD 40.57 pppy and 8.70 pppy, respectively. Thirty-eight patients (4 percent) were hospitalized and presented a median cost of 3,656 per patient per hospitalization with a cost equivalent to 53.1 percent of total expenses. Total costs of patients with HbA1c ≤ 7 percent were lower for this group and also costs of medications and consultations, whereas for patients with HbA1c ≤ 8 percent, only total costs and costs of medications were lower when compared with HbA1c > 8 percent patients.Conclusions:Medications and hospitalizations were the major contributor of diabetes expenses. Preventing T2DM, or reducing its complications through adequate control, may help avoid the substantial costs related to this disease.

RÉSUMÉDes données de référence nationales et représentatives de l’Étude longitudinale canadienne sur le vieillissement (ÉLCV) ont été utilisées pour évaluer si la possession d’un animal de compagnie était associée à la participation sociale et à la satisfaction de vivre des personnes âgées (≥65 ans, n= 7,474). Des statistiques descriptives ont permis de distinguer les modalités de la possession d’animaux dans la population canadienne plus âgée, et des modèles de régression logistique ont été utilisés pour estimer les associations entre la participation sociale et la satisfaction de vivre de personnes âgées possédant ou non des animaux. Un tiers des personnes âgées de l’échantillon ont rapporté posséder des animaux. En moyenne, les personnes possédant des animaux avaient une satisfaction de vivre inférieure (OR=0,73, p<0,001) et participaient à moins d’activités sociales, récréatives et culturelles sur une base régulière (OR=0,73, p<0,001) que les personnes sans animaux; cependant, les personnes avec animaux n’étaient pas moins satisfaites de leur niveau actuel de participation sociale que celles sans animaux. Pour les propriétaires d’animaux dont la participation sociale était compromise, les animaux semblaient constituer un facteur de protection dans certaines circonstances. Des caractéristiques individuelles et des facteurs structurels liés au cadre conceptuel des Collectivités amies des aînés de l’Organisation mondiale de la Santé ont permis de mieux comprendre ces résultats.
The Use of Positive Words in Political Science Language
Authors: Weidmann Nils B. , Otto Sabine , Kawerau Lukas 
Published: April 2018

ABSTRACTPolitical science takes pride in objective and methodologically rigorous research. This should be reflected in a clear and concise writing style that convinces readers by the content of the research, not by the language used to report about it. This article demonstrates that this is true but only to a limited extent. It shows that—similar to recent findings from natural-sciences research—the frequency of positive words that political scientists use to describe their research has increased markedly in recent decades. At the same time, however, the magnitude of this increase is much less pronounced. The article discusses and analyzes potential explanations for this trend. We suspect that it can be attributed at least partly to changing norms in the discipline, in which research framed in a positive way is more likely to be published.
Conservatism and Women's Political Representation
Authors: Celis Karen , Childs Sarah 
Published: April 2018

Abstract
Conservative political actors appear rather troubling for many gender and politics scholars and feminist activists. What should we make of their claims to represent women? How should we best understand their actions? This article, based on a critical rereading of the empirical literature and informed by contemporary representation theory, develops a new conceptual framework for assessing the quality of women's substantive representation by conservatives. We find that under specified conditions, conservative representatives do further women's substantive representation. A first set of conditions relates to conservative claims to represent women. These are considered to be “for women” when they marry conservative women's concerns in society; when conservative representatives act and do not simply engage in rhetoric; and when their actions are not undercut by other acts, policies, or outcomes unfavorable to women. A second set of criteria considers the quality of the process of women's substantive representation. We contend that a feminist process of deliberation about women's interests can include conservative claims as long as they meet the requirements of responsiveness, inclusiveness, and egalitarianism.
Clopyralid Tolerance in Strawberry and Feasibility of Early Applications in Florida

AbstractBroadleaf species escape current integrated weed management strategies in strawberry [Fragaria×ananassa (Weston) Duchesne ex Rozier (pro sp.) [chiloensis×virginiana]] production. Clopyralid is a registered POST control option, but current application timings provide suppression of only some species. Earlier clopyralid application timings may increase spray coverage to weeds at the planting hole, but strawberry plant tolerance to applications shortly after transplant is unknown. The objectives of the study were to determine the degree of clopyralid tolerance when applied to mature strawberry plants according to current management strategies, whether clopyralid absorption and translocation were involved in the tolerance response demonstrated by mature strawberry plants, and whether clopyralid could be safely applied to immature strawberry plants shortly after transplant. Clopyralid caused no damage when applied to mature strawberry plants and did not affect crop height, number of crowns, flowers, immature berries, or yield. Maximal strawberry absorption of radiolabeled clopyralid was 82% of the recovered radioactivity and reached peak (90%) absorption at 15 h. Maximal total translocation of radioactivity from the treated leaf was 17% and reached peak translocation at 52 h. Translocation was primarily to the new leaves and reproductive structures. In the early-application experiment, damage induced by clopyralid for all application timings reached 0 by 8 wk after treatment. Across all timings, maximal damage at 140 g ha−1was 17% when applied 14 d after transplant (DATr) and 56% at 28 g ha−1when applied at 21 DATr. Clopyralid dose did not affect the number of crowns, aboveground biomass, or yield. There was some stunting in plant height (3%) by the high labeled dose of clopyralid. Labeled dose clopyralid applications appear safe for application timings closer to strawberry transplant, though considerations of leaf cupping should be taken under consideration for label changes.
Combining the Post-Cue Task and the Perceptual Identification Task to	Assess Parallel Activation and Mutual Facilitation of Related Primes and	Targets
Authors: Scherer Demian , Wentura Dirk 
Published: April 2018

Abstract. Recent theories assume a mutual facilitation in case of semantic overlap for concepts being activated simultaneously. We provide evidence for this claim using a semantic priming paradigm. To test for mutual facilitation of related concepts, a perceptual identification task was employed, presenting prime-target pairs briefly and masked, with an SOA of 0 ms (i.e., prime and target were presented concurrently, one above the other). Participants were instructed to identify the target. In Experiment 1, a cue defining the target was presented at stimulus onset, whereas in Experiment 2 the cue was not presented before the offset of stimuli. Accordingly, in Experiment 2, a post-cue task was merged with the perceptual identification task. We obtained significant semantic priming effects in both experiments. This result is compatible with the view that two concepts can both be activated in parallel and can mutually facilitate each other if they are related.
Influence of the Interaction Between Typhoons and Oceanic Mesoscale Eddies on Phytoplankton Blooms
Authors: Liu Fenfen , Tang Shilin 
Published: April 2018

AbstractPhytoplankton blooms induced by the interaction between typhoons and oceanic mesoscale eddies in the South China Sea were investigated using the composite averaging method based on cyclone‐centric coordinates from nine years (2002–2010) of satellite observations. Increases in the chlorophyll (Chl) concentration following the passage of a typhoon differed greatly among the pre‐existing cyclonic eddy (PCE), pre‐existing anticyclonic eddy (PACE) and non‐eddy (NE) ocean conditions (with Chl increases of approximately 35%, 6% and 12%, respectively), but the magnitude of sea surface temperature (SST) cooling was similar under the three conditions (∼1°C). Under the same level of SST decreases, the greater increase in the Chl concentration in the PCE condition was attributed to the longer persistence of both SST cooling and nutrient input caused by the typhoon‐strengthened PCE (associated with upwelling), which stopped the re‐warming of the typhoon‐induced cold water.
