LGBTQ Music Educators: External Mentoring Between Student Teachers and In-Service Teachers
Authors: Taylor Donald M.
Published: June 2018

The purpose of this instrumental case study was to examine what LGBTQ (i.e., lesbian, gay, bisexual, transgender, queer, or questioning) student teachers in music classrooms might learn from LGBTQ music teachers who served as external mentors outside the classroom setting. During the student teaching semester, 3 LGBTQ student teachers were each paired with a music teacher whose LGBTQ identity matched their own and who taught near the geographical region where student teachers hoped to secure employment. Each week, student teachers communicated with mentors via journaling, phone conversations, or videoconferencing. Additional sources of data were collected through individual interviews, focus groups, and Facebook postings. Across all cases, student teachers grappled with issues of LGBTQ presentation, providing student support and environmental contexts. Older teachers in socially conservative climates advised a cautious approach toward LGBTQ identity in the classroom, whereas the youngest mentor advised normalizing LGBTQ topics through full disclosure. Findings are discussed regarding the varied sociopolitical contexts LGBTQ music educators may encounter.

Published: June 2018

Background: The unprecedented nationwide outbreak of the Middle East Respiratory Syndrome Coronavarius (MERS-CoV) from June to July in 2015 took the Korean healthcare system unexpectedly and created physical and psychological stress and trauma to Registered Nurses unprepared to deal with the viral outbreak.Purpose: We investigated the effects of Middle East Respiratory Syndrome Coronavirus (MERS-CoV), post-traumatic stress disorder (PTSD) and burnout among Korean registered nurses (RNs).Methods: A descriptive cross sectional design using a self-administered survey of a convenience sample of 112 Korean RNs. The Impact of Event Scale-Revised-Korean version (IES-R-K) for PTSD and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) for burnout were utilized.Results: Overall prevalence for symptoms of PTSD was 50.0%. PTSD was significantly correlated to burnout (r = .480, p = .000), especially two burnout subscales, emotional exhaustion (r = .533, p = .000), and depersonalization (r = .497, p = .000).Conclusions: Future anticipatory guidance and management of traumatic outbreak or disaster should be considered for nurses’ mental health. Public health and safety at the national level must address quality health outcomes for both patients and healthcare professionals alike.
Integrating Unmanned Aerial Systems Into the Crop Production System Through On-Farm Research
Authors: Adkins Kevin Allan , Bailey Christen C. , Taylor Aspen E.
Published: June 2018

Precision agriculture strives to manage variations in the field in order to increase yield while adapting input factors to preserve resources and decrease production costs. Unmanned aerial systems (UAS) are advancing precision agriculture by allowing for nondestructive and convenient, as well as cost and time efficient mapping of spatial variation in fields with higher spatial resolution than previous methods. However, while there is much anticipation regarding the potential role for UAS in precision agriculture, their role still requires additional application-based testing. The objective of this work was to explore how growers best integrate the UAS product into their farm workflow. Two on-farm investigations were undertaken with vegetable growers for the duration of a growing season. Combinations of two unique unmanned aircraft (UA) platforms fitted with two different multispectral sensors were used to gather spectral reflectance data. The investigations found that the UAS product enabled the growers to optimize their field management practices, while overcoming a labor shortage, and create a more sustainable operation.

The endosperm chalkiness in grains is one of the most important traits in rice grain qualities, and grain chalkiness directly determines grain quality and market price. Therefore, the endosperm chalkiness reduction is an important goal of breeding scientist in rice. However, little is known about the relationship of the formation of rice endosperm chalkiness and the morphological structure and development in fragrant japonica and conventional japonica varieties. In this study, we have mainly investigated the chalkiness characters such as degree of endosperm chalkiness (DEC), chalkiness rate (CR) and chalkiness area (CA) in 12 fragrant japonica varieties and 9 conventional japonica varieties. Furthermore, the endosperm structure and starch granules of rice grains were also observed with scanning electron microscope (SEM). The results indicated that the 21 varieties including the different fragrant japonica and conventional japonica varieties has a linear relationship between the DEC and the CR (P < 0.05). Among the fragrant japonica and conventional japonica varieties, the biggest difference is the CR, follow by CA and DEC. In addition, there is a certain correlation between the arrangement of endosperm cells, the distribution of starch granules and the occurrence of chalkiness characters in the different fragrant japonica and conventional japonica varieties. For the same fragrant japonica or conventional japonica variety, there is no significant difference between the starch granules from the transparent parts of chalkiness and non-chalky, while the starch granules of grains between chalky and non-chalky has obvious difference. Our results would provide important references for high quality rice breeding.

Published: June 2018

Studies on natural enemies are important to find new species and to develop management strategies to preserve them to help control pests in biological control programs. For the state of Mato Grosso, Brazil, which comprises the Amazon, Cerrado, and Pantanal biomes, few studies have been conducted on the diversity of these parasitoids, possible endemic and/or new species, as well as their potential as natural enemies. Thus, the present study was aimed at describing the diversity of parasitoids of the families Ichneumonidae (Hymenoptera) and Tachinidae (Diptera) associated with pest lepidopterans in soybean crops. Weekly sampling of pest lepidopterans was carried out during four soybean seasons (2009/2010, 2010/2011, 2011/2012 and 2012/2013). Parasitoid larvae were observed in the main lepidopteran pest species of soybean during the four soybean seasons. Three genera of the Ichneumonidae family, belonging to the genera Microcharops Roman, Ophionellus Westwood, and Podogaster Brullé. Six genera of the Tachinidae family occur in the state of Mato Grosso in soybean fields. The following genera were recorded: Archytas spp. Jaennicke, Phorocera spp. Robineau-Desvoidy, Gymnocarcelia spp. Townsend, Lespesia spp. Robineau-Desvoidy, Eucelatoria spp. Townsend, Chetogena spp. Rondani. These parasitoids were found parasitizing caterpillars of the Noctuidae (Lepidoptera), in species that had not yet been reported as hosts for the Neotropical region. Further studies are needed on the beneficial entomofauna and their preservation in agricultural environments.
Invasive Lantana camara L. Shrub in Ethiopia: Ecology, Threat, and Suggested Management Strategies
Authors: Abebe Firew Bekele
Published: June 2018

Lantana camara L. is one of the worst invasive alien species that are categorized worldwide. The objective of this review paper was to review the dispersal and threats posed by Lantana camara L. in Ethiopia and based on review results, to suggest management strategies that can bring solutions to the threats posed by the weed. Both biological characteristics of Lantana camara L. and its dispersal agents have contributed to the success of its dispersal. Even though Lantana camara L. is dispersed in other places within Ethiopia, Debrezeit, Dire Dawa, Harar and Somali are the hotspot areas for the weed. Biodiversity and potential agricultural loss, human and animal health problems and infestation in national parks are the identified threats that Lantana camara L. posed within the country. Utilization of Lantana camara L. for various purposes, prevention of its further dispersal into non-infected areas, use of fire, mechanical and biological control and awareness creation are the suggested management strategies that can bring solutions to the threats posed by the weed within the country.

Published: June 2018

This study was to evaluate the nutrition and the agronomic part of bean intercropped with castor crops submitted to sources and levels of B in the Anápolis-GO, Brazil. The treatments consisted of two sources of B (borax = 11% B and boric acid = 17% B) combined with five levels of B (0.0, 0.5, 1.0, 2.0 and 4.0 kg ha-1 in soil) in bean intercropped with castor, plus monoculture, using 1.0 kg ha-1 B. That leaf levels of B and S in beans, and of B, N, Ca, Mg and Fe in castor were influenced by the sources and levels of B in the intercropping. The bean yield intercropped with castor was not influenced by borated fertilization, neither by the interaction of factors. The highest yield of castor intercropped with beans, 2.040 kg of grains ha-1, was obtained with the 1.9 kg ha-1 of B, regardless of the source used.
Prioritising the Replanting Schedule of Seedling Tea Fields on Tea Estates for Drought Susceptibility Measured by the SWAPDT Method in the Absence of Historical In-filling Records

Published: June 2018

Due to the unpredictable natural droughts that occur, causing tea farmers significant losses in tea estates, a two-day method for distinguishing between drought tolerant (DT) and drought susceptible (DS) Camellia sinensis cultivars was developed. This work was based on known cultivars developed at the Tea Research Institute in Kenya and the Tea Research Foundation for Central Africa in Malawi. This paper contains an in-depth description of the application of the SWAPDT method on four 60-year old, C. sinensis seedling fields in Kenya. The in-filling history of the four fields due to drought-related deaths was obtained from historical records. The SWAPDT method scores correlated very well with the historical records. It has been indicated, from the results obtained in this study, that a sample size of 20 tea trees is sufficient to accurately determine the drought susceptibility of a large tea field of approximately 5-20 hectares, containing 50 000-200 000 tea trees, were the difference between their mean values, as measured by the SWAPDT method, is approximately 10%.

Published: June 2018

The cultivation of basil is worth mentioning, because it is a very promising crop. The aim of this study was to evaluate the development of the Basil cultivation, cultivar Tuscan lettuce leaf and Alfavaca red basilican, submitted to different doses of nitrogen. The first factor was composed of six nitrogen doses and one control (0, 40, 80, 120, 160, 200, 240 kg ha-1 of nitrogen), and the Second was composed of two cultivars (Alfavaca red basilican and Tuscan lettuce leaf) with four replicates. The basil Alfavaca red basilican cultivar overcame the cultivar Tuscan lettuce leaf in the plant height and diameter of the stem. In the leaf and shoot dry matter variables, the doses that resulted in the greatest increase of dry matter were 128 and 125.62 kg ha-1 of nitrogen for the cultivar Tuscan of lettuce leaf. Both Alfavaca red basilican and Tuscan lettuce leaf were influenced by nitrogen fertilization and the dose of 120 kg ha-1 of nitrogen has the highest potential in the developmental parameters.

Published: June 2018

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

Published: June 2018

The efficacy of rosemary essential oil (REO), as feed additive, on growth and blood constituents of growing New Zealand White (NZW) rabbits was evaluated. Thirty six NZW were distributed into four groups: 1 control and 3 treated groups. The control was fed the basal diet, while feeds of other treatments were fortified with 0.25, 0.50 and 0.75 g/kg REO for groups 2, 3 and 4, respectively. The criteria of response were growth performance, carcass traits, blood glucose, plasma lipids, immunoglobulins, total antioxidant capacity (TAC), malondialdehyde (MDA) and testosterone concentrations. Results revealed that REO supplementation had no critical impacts on growth performance, carcass yeild or blood glucose. Rabbits recieving dietary REO exhibited lower lipid profile and higher immunoglobulins A than those of the control. The treated rabbits displayed significantly higher TAC than the basal group with the best reaction for those fed G3 diet. In a similar way, MDA was reduced essentially by including REO. There was a significant increase in testosterone levels due to added REO. The present results indicate that supplemental REO at 0.5 g/kg of diet has a beneficial impact on lipid profile, immunity and antioxidant status of rabbits.
Synergistic Effect of Phosphine and Carbon Dioxide on the Mortality of Tribolium castaneum (Coleoptera: Tenebrionidae) in Paddy
Authors: Meenatchi R. , Alice R. P. S. J. , Paulin P. P.
Published: June 2018

Phosphine (PH3) is widely used as a fumigant for the control of stored product pests. Indiscriminate use of PH3 leads to the development of resistant strains. Thus, an experiment was conducted in a laboratory scale fumigation chamber to determine the synergistic effect of carbon dioxide (CO2) and PH3 on the mortality of Tribolium castaneum during fumigation of paddy. PH3 gas generation varies depending upon grain moisture content and dosage of PH3 used for fumigation treatment. Thus, the maximum PH3 concentration with respect to saturation time was achieved when paddy were treated with 98% CO2 + 3 ppmPH3 at 17% moisture content, leading to a quick mortality of different life stages of T. castaneum with minimum LT50 and LT99 value. Among the different stages of T. castaneum, pupal stage was more resistant to all the treatments compared to larva and adult stages. PH3 residues in all the treatments were below the recommended level and it can be considered as safe for consumption.

De casus ‘Gronddossier Palmen’ Rekenkameronderzoek voor een diep verdeelde gemeenteraad

Het is nog een twistpunt of rekenkamercommissies met raadsleden in de wet mogelijk blijven. Deze bewijzen evenwel continu hun effectiviteit en toegevoegde waarde in het lokale bestuurlijke bestel. Ook, en misschien juist, in politiek gevoelige situaties. Dat wordt in dit artikel aangetoond aan de hand van de casus van het zogenoemde gronddossier Palmen in Brunssum. De ophef over een integriteitskwestie rond de wethoudersbenoeming van Palmen in oktober 2017 reikte tot ver buiten de gemeentegrenzen, tot in Den Haag aan toe. Op verzoek van de raad heeft de rekenkamercommissie Brunssum de feiten van het dossier gereconstrueerd met stukken en gebeurtenissen die gerelateerd waren aan een grondtransactie uit 1976. Door een vooronderzoek uit te voeren, scherp te blijven op de grenzen van de taak van de rekenkamercommissie en de opdracht, en waarborgen in het onderzoeksproces in te bouwen kon de rekenkamercommissie het onderzoek adequaat uitvoeren. Daarmee werd de raad in staat gesteld eigenstandig zijn mening te vormen over een complex dossier en daarmee indirect over de betreffende integriteitskwestie.
O DIÁLOGO, O ACONTECIMENTO E A CRIAÇÃO DE CENAS DE DISSENSO EM CONTEXTOS ORGANIZACIONAIS
Authors: MARQUES Ângela Cristina Salgueiro , MAFRA Rennan Lanna
Published: June 2018

Este artigo tem como objetivo compreender os mecanismos de operação do diálogo quando mobilizado nos contextos organizacionais. Inicialmente, buscaremos entender que o diálogo emerge nos contextos organizacionais a partir de um acontecimento que provoca a abertura de campos comunicativos sempre conflituosos. Em seguida, argumentamos que as interações provocadas pelo acontecimento dão origem a comunidades políticas que se manifestam em cenas de dissenso nas quais os integrantes dessas comunidades instituem um drama ancorado em gestos poéticos e argumentativos, voltados à sua própria constituição como interlocutores em torno de uma pretensa igualdade moral e política. Por fim, buscaremos entender como as comunidades políticas, que emergem das cenas de dissenso acontecimentais ao mesmo tempo em que as constróem, se valem do diálogo para dar visibilidade a (fazer aparecer) suas próprias diferenças em práticas articulatórias imprevisíveis, fragmentadas e conflituosas.

Heterotopias Fotojornalísticas
Authors: Marocco Beatriz , Ramos Júlia Capovilla Luz
Published: June 2018

O presente trabalho se debruça sobre o conceito de heterotopia (FOUCAULT, 1987; 1998; 2005), para entender os blogs de fotografia dos jornais de maior circulação no Brasil como espaços que se diferenciam dos periódicos impressos não somente em função do suporte de publicação das fotografias, mas principalmente por engendrarem dinâmicas produtivas distintas, apesar das dependências complexas que operam e deixam transparecer quando investigamos este material mais de perto. A produção imagética presente nos blogs mostra o esforço por parte dos fotojornalistas em criar um espaço outro para publicação das fotografias sem, contudo, deixarem de refletir sobre a natureza da operação que executam, as limitações contidas na própria ferramenta blog e a vontade de incluir mais liberdade e poesia em tais produções.
Narrativas digitais no jornalismo: a interatividade encenada
Authors: Peixinho Ana Teresa , Marques Inês Fonseca
Published: June 2018

Desde o advento da WEB2.0, o Jornalismo tem sofrido profundas alterações a vários níveis. Nesta comunicação, as autoras propõem-se focar a atenção nas mudanças retórico-textuais, patentes no aparecimento de novos suportes que têm permitido novos modelos de texto e novas formas de reportar. Com base numa análise de caso, que tem como corpus um conjunto de cinco reportagens interativas, publicadas entre abril e setembro de 2015, e anunciadas pela SIC como inovadoras, pretende-se problematizar as transformações narrativas no Jornalismo, decorrentes do advento da hipertextualidade digital. Se é já sabido, como bem o tentou demonstrar João Canavilhas há uma década, que a tradicional superestrutura da notícia – a pirâmide invertida – foi progressivamente substituída no jornalismo online pela “pirâmide deitada” (CANAVILHAS, 2006 e 2007); se os estudos narrativos têm admitido, nos últimos anos, a necessidade de uma reconfiguração dos seus aparelhos analíticos e teóricos, em função da produção e consumo de narrativas hipertextuais (LITS, 2014; RYAN, 2001); se, como certos autores revelam, o jornalismo tem sido preenchido pela atividade do storytelling digital (ALEXANDER, 2011; RYAN, 2006) cremos, apesar de tudo, não ter sido ainda claramente demonstrado em que medida as narrativas jornalísticas, de facto, se alteraram. Tentar-se-á, por agora, através do estudo de caso, perceber em que medida a interatividade anunciada com entusiasmo pela SIC se concretiza nessas reportagens. Para o efeito, parte-se do conceito de interatividade, como reconhecida propriedade hipertextual, para questionar a sua prática nas reportagens do webjornalismo.
Interfiro, logo existo: como a audiência potente muda a rotina jornalística no mais antigo jornal em circulação da América Latina
Authors: Mesquita Giovana
Published: June 2018

Em um momento de transformações no jornalismo entendíamos a importância da imersão na "fábrica" onde se produz a notícia – a redação –, para acompanhar, no dia a dia, as mudanças ocasionadas pelas novas formas de relacionamento entre audiência e jornalismo, pós a Web 2.0, que acabam estabelecendo modificação nas rotinas produtivas, levando os jornalistas a assumir novos papeis. Com acesso a Internet e a dispositivos moveis, a audiência informa, fotografa, filma e coloca nos Trending Topics (TTs) os assuntos que considera importantes e acaba se envolvendo ou sendo envolvida pelos veículos de referência na produção noticiosa. Os objetivos do artigo são analisar as mudanças que vêm acontecendo no jornalismo a partir desse envolvimento da audiência, que denominamos potente e refletir sobre novos perfis profissionais que surgem nas redações, a exemplo do Editor de Mídias Sociais. É parte de uma pesquisa que teve como um dos objetos um veículo de referência brasileiro, o Diario de Pernambuco, jornal mais antigo em circulação da América Latina, que fica sediado no Recife, capital do Estado de Pernambuco, no Brasil.

Máquina de ver, máquina de visão: sobre usos profanatórios e subjetivações potenciais do Oculus Rift enquanto dispositivo
Authors: Alvarenga Nilson Assunção , Monteiro Ana Maria Vieira
Published: June 2018

Diante dos atuais aparelhos de realidade virtual, que vêm ganhando a atenção dos desenvolvedores de jogos e aplicativos diversos, surgiu a necessidade de tomar o mais destacado deles, o Oculus Rift, e situá-lo em um referencial teórico, questionando-o quanto aos seus usos potenciais nas artes. Para tanto, partimos da análise de um campo de forças que atuam nos dispositivos dos quais o Oculus é precursor. Forças essas que, conforme propomos, encontram-se na tensão entre os usos previstos e os usos potenciais, sendo que os últimos, contextualizados no horizonte de uma filosofia do dispositivo, poderiam ser pensados a partir das noções de subjetivação, com Deleuze, e de profanação, com Agamben. No entanto, como buscamos contrapor, são raras as intervenções que atualizam as potências do dispositivo. Enquanto isso, um experimento chamou nossa atenção para o que se busca, com este artigo, trabalhar: modos pelos quais se pode pensar um uso profanatório de headsets de realidade virtual. Concluímos com reflexões sobre como o experimento Gender Swap joga com as forças que perpassam o dispositivo, apontando para potenciais subjetivações que rompem com suas linhas duras.
Museu como medium: reflexões sobre as interfaces entre comunicação e museologia
Authors: Souza Lucimery Ribeiro , Cal Danila
Published: June 2018

O objetivo deste trabalho é refletir sobre as interfaces entre Comunicação e Museologia. Propõe-se a ideia do museu como medium, considerando-o como ambiente de comunicação. De cunho teórico, o artigo parte das ponderações de literaturas dos campos da Comunicação e da Museologia a fim de compreender melhor os modos pelos quais a comunicação nos museus vem sendo abordada e reafirmar a postura democratizante dessa instituição perante a sociedade. Nesse cenário, os recursos tecnológicos destacam-se no processo de ressignificação das informações circuladas na sociedade. Conclui-se que, no desafio imposto pela conjugação de lazer e educação, as tecnologias de informação e comunicação contribuem para a disseminação, o conhecimento e ampliação do acesso aos acervos da instituição, permitindo a reconfiguração das relações entre museu e sociedade, além das potencialidades de preservação dos acervos e de interatividade com públicos distintos.
A Zona de Convergência do Atlântico Sul: uma visão e revisão críticas
Authors: Villela Rubens Junqueira
Published: June 2018

A Zona de Convergência do Atlântico Sul (ZCAS) é uma alongada e persistente banda de intensa convecção que na época de verão e com certa frequência se estende da Amazônia ao oceano ao largo das costas brasileiras, exercendo papel significativo no regime pluviométrico do País. Juntamente com suas congêneres do Pacífico e do Índico, constitui uma nova categoria de organismo meteorológico de larga escala, identificado a partir da década de 1970 através da análise de observações de satélite. A explicação do fenômeno é ainda um desafio para a meteorologia e climatologia; essencialmente, resulta de uma intensa interação entre sistemas tropicais e de latitude média. Neste trabalho, recapitulamos uma parte da evolução histórica dos conhecimentos sobre o assunto, incluindo, além das contribuições de pesquisadores brasileiros, os providenciais estudos japoneses comparando a ZCAS com a Baiu, e apresentamos descrições resumidas de eventos de ZCAS no Brasil. Como complemento, reportamo-nos a dois eventos de precipitações destrutivas no Estado de São Paulo, de natureza frontal, a comparar com a atuação da ZCAS.
A storm of opinions on Brexit referendum
Authors:   Sens public, Lingeswaran Amudha
Published: June 2018

June 23rd, 2016 Brexit referendum will have incalculable consequences. It may be
surprising to see Britain leaving the European Union while UK negotiated some
advantageous positions. But a referendum is a risky bet : it allows all opponents to
add their voices while the Remaining Campaigns had to gather many people who were
not ready to give David Cameron a carte blanche (This aspect also explains why Scots
could vote for Europe, as their vote was clearly not backing Cameron). Whatever will
be happening, this vote is a great victory for populism in Europe. Clairvoyance is
urgently needed from the European leaders to relaunch a continental dynamics after
this disavowal.
Le ciel du Centaure - de la métamorphose à l’œuvre
Authors: Zarader Jean-Pierre
Published: June 2018

Si tous les films de Hugo Santiago, depuis Invasion et Les autres jusqu’au Loup de la
côte Ouest, relèvent d’une interrogation indissolublement cinématographique et
philosophique, Le ciel du Centaure, son dernier film, est une fiction aux accents
politico-mafieux qui brouille la frontière entre théorie et fiction. Une histoire de
faussaires conduit Santiago à filmer la création dans ce qu’elle a de plus énigmatique, son
inscription dans une tradition et une histoire dont elle hérite, mais qu’elle excède, à
filmer la métamorphose d’une oeuvre et celle d’un homme dans leur opposition au réel et au
vieux fleuve héraclitéen. Cette approche cinématographique de la transmission, de la dette
et de la trace, est une véritable jubilation, au plus près de l’imaginaire du
cinéma.
F(f)rancophonies : Une « part manquante » de la diplomatie ?
Authors: Ramel Frédéric
Published: June 2018

Le français fut un outil majeur de communication dans les relations diplomatiques. Aujourd’hui, cet usage est de moins en moins avéré, notamment au sein des organisations intergouvernementales qu’elles soient universelles ou régionales. Néanmoins, la dimension linguistique ne doit pas occulter d’autres aspects qui révèlent la présence de plusieurs francophonies à l’œuvre sur la scène diplomatique : des institutions francophones (l’Organisation Internationale de la Francophonie et ses opérateurs), aux acteurs francophones émanant de la société civile. Comment ces différentes francophonies perçoivent leur rôle dans un système international contemporain caractérisé par une série de changements saillants sur le plan de sa structure (redistribution des capacités de puissance avec l’éclosion des « émergents ») ou bien de sa nature (homogénéisation partielle des valeurs et critique de l’occidentalisation du monde) ? C’est là l’objet de cet article qui aura deux principaux objectifs : identifier le répertoire d’action diplomatique privilégié par les acteurs institutionnels francophones et qualifier le rôle diplomatique exercé par les F(f)rancophonies allant de la logique du désenclavement à la posture du renforcement des capacités.

Previous work on the US Atlantic coast has generally shown that coastal foredunes are dominated by two dune grass species,Ammophila breviligulata(American beachgrass) andUniola paniculata(sea oats). From Virginia northward,A. breviligulatadominates, whileU. paniculatais the dominant grass south of Virginia. Previous work suggests that these grasses influence the shape of coastal foredunes in species-specific ways, and that they respond differently to environmental stressors; thus, it is important to know which species dominates a given dune system. The range boundaries of these two species remains unclear given the lack of comprehensive surveys. In an attempt to determine these boundaries, we conducted a literature survey of 98 studies that either stated the range limits and/or included field-based studies/observations of the two grass species. We then produced an interactive map that summarizes the locations of the surveyed papers and books. The literature review suggests that the current southern range limit forA. breviligulatais Cape Fear, NC, and the northern range limit forU. paniculatais Assateague Island, on the Maryland and Virginia border. Our data suggest a northward expansion ofU. paniculata,possibly associated with warming trends observed near the northern range limit in Painter, VA. In contrast, the data regarding a range shift forA. breviligulataremain inconclusive. We also compare our literature-based map with geolocated records from the Global Biodiversity Information Facility and iNaturalist research grade crowd-sourced observations. We intend for our literature-based map to aid coastal researchers who are interested in the dynamics of these two species and the potential for their ranges to shift as a result of climate change.

Sponge-associated prokaryotic diversity has been studied from a wide range of marine environments across the globe. However, for certain regions, e.g., Vietnam, Thailand, Cambodia, and Singapore, an overview of the sponge-associated prokaryotic communities is still pending. In this study we characterized the prokaryotic communities from 27 specimens, comprising 18 marine sponge species, sampled from the central coastal region of Vietnam. Illumina MiSeq sequencing of 16S ribosomal RNA (rRNA) gene fragments was used to investigate sponge-associated bacterial and archaeal diversity. Overall, 14 bacterial phyla and one archaeal phylum were identified among all 27 samples. The phylumProteobacteriawas present in all sponges and the most prevalent phylum in 15 out of 18 sponge species, albeit with pronounced differences at the class level. In contrast,Chloroflexiwas the most abundant phylum inHalichondriasp., whereasSpirastrellasp. andDactylospongiasp. were dominated byActinobacteria. Several bacterial phyla such asAcidobacteria, Actinobacteria, Bacteroidetes, Chloroflexi, Deferribacteres, Gemmatimonadetes, andNitrospiraewere found in two-thirds of the sponge species. Moreover, the phylumThaumarchaeota(Archaea), which is known to comprise nitrifying archaea, was highly abundant among the majority of the 18 investigated sponge species. Altogether, this study demonstrates that the diversity of prokaryotic communities associated with Vietnamese sponges is comparable to sponge-prokaryotic assemblages from well-documented regions. Furthermore, the phylogenetically divergent sponges hosted species-specific prokaryotic communities, thus demonstrating the influence of host identity on the composition and diversity of the associated communities. Therefore, this high-throughput 16S rRNA gene amplicon analysis of Vietnamese sponge-prokaryotic communities provides a foundation for future studies on sponge symbiont function and sponge-derived bioactive compounds from this region.
América Latina y conflicto social en el siglo XXI: Escenarios y debates sobre el descuajeringamiento de la relación Estado, mercado y sociedad civil
Authors: Faundes Peñafiel Juan Jorge
Published: June 2018

Se revisan los escenarios sociopolíticos latinoamericanos considerando el mayor o menor avance del proyecto neoliberal y su relación con los movimientos sociales; los debates y consensos sobre la acción colectiva, los movimientos sociales y la llamada «crisis» de los partidos políticos. El trabajo se aborda, primero, desde la matriz, «nacional-social-popular» o «Matriz Socio Política», que distingue entre el rol del Estado, el sistema de representación política que media con la sociedad, institucionalizando las demandas o conflicto sociales, pero que ha sido desarticulada ante el escenario actual de la sociedad «postindustrial globalizada» latinoamericana y se confronta con la propuesta de una matriz «mercado-céntrica» de «Estadomercado-sociedad civil»
“La mediación penal: una buena herramienta en la resolución de conflictos”
Authors: Paredes Galiana Laura , García-Longoria  Serrano María Paz
Published: June 2018

Esta investigación trata acerca del conocimiento, la opinión y la percepción que tienen los profesionales de la justicia en la Región de Murcia sobre la Mediación Penal, así como su posibilidad de implantación.El método cuantitativo se configuró a partir de la técnica de la encuesta. La muestra utilizada ha sido de treinta y tres personas, relacionadas con el ámbito judicial. Los principales resultados destacan que es una buena alternativa porque se podrían resolver conflictos de tipo no material, tales como los componentes psicológicos, emocionales y de relación. Se apuntan como ventajas la rapidez del proceso y la posibilidad de una mayor comunicación entre las partes. Entre los inconvenientes se destacaron la posibilidad de utilización de la mediación por parte del ofensor para obtener únicamente un beneficio propio. Para la víctima las ventajas se centran en comprender la situación del agresor, la comprensión de los hechos que rodearon la situación, reducir o eliminar los miedos que puede tener a la repetición de los hechos, así como la posibilidad de llegar a un acuerdo satisfactorio. Respecto a los ofensores, se destacaron como ventajas la posibilidad de rebajar la pena, así como beneficios de tipo psicológico: la posibilidad de pedir perdón o el reconocimiento de los hechos.
Rechazo de solicitudes de opinión consultiva por parte de la Corte Interamericana de Derechos Humanos
Authors: Paul Díaz Alvaro
Published: June 2018

La Corte Interamericana de Derechos Humanos tiene una función consultiva muy amplia, tanto por los legitimados para solicitar una opinión como por los temas que puede tocar. No obstante esta amplitud, declina referirse a algunas solicitudes de opinión consultiva. Los motivos para hacerlo son variados, y han sido desarrollados por la Corte a través de su jurisprudencia. Este trabajo sistematiza tales dictámenes y analiza la extensión y conveniencia de los criterios elaborados por la Corte
Geopolítica en América del Sur: Desde la militarización de la disciplina a la necesidad del debate académico
Authors: Cabrera Lester
Published: June 2018

El presente artículo tiene por objetivo analizar algunos de los factores que han llevado a la utilización de la geopolítica en América del Sur como un concepto amplio y vago que busca explicar algunos procesos internacionales. Para lograr lo anterior, al mismo tiempo que se problematiza a la geopolítica desde su concepto, se realizará una descripción histórica sobre su evolución en la región mencionada, tomando en cuenta tanto el contexto regional, la percepción geopolítica de algunos actores, como también el papel que jugaron los militares en el desarrollo de la disciplina, especialmente durante la Guerra Fría. Así también, se tomarán en cuenta algunos de los elementos que establecen la necesidad de aumentar el debate dentro de la disciplina, desde la óptica de la universidad, producto de la existencia de aspectos que desde la visión “tradicional” de la disciplina, no se pueden entender, tales como la identidad y la visión de espacio. Se concluye que resulta necesario para el desarrollo de la disciplina en la región, un debate entre la academia y los estamentos armados en la disciplina de la geopolítica, para tener una mejor comprensión de lo que se entiende, y lo que no se entiende, por geopolítica.
Objeción de conciencia empresarial y “guerra de religión” en los Estados Unidos. Reflexiones a partir de Burwell v. Hobby Lobby Stores, Inc.
Authors: Vázquez Alonso Víctor Javier
Published: June 2018

En este trabajo se analiza el debate actual existente en la doctrina norteamericana sobre la objeción de conciencia empresarial. Para ello, después de resumir la evolución de la doctrina judicial de la Free Exercise Clause en relación a la objeción al cumplimiento de obligaciones legales, nos centraremos en la última jurisprudencia de la Corte Suprema, en el caso Burwell v. Hobby Lobby Stores, Inc., donde, sobre la base de la Religious Freedom Restauration Act federal, la mayoría del Tribunal reconoce el derecho de las empresas a eximirse de costear, dentro del seguro de sus trabajadoras, aquellos tratamientos anticonceptivos contrarios a su ideario religioso. Después de llevar a cabo una lectura crítica de esta jurisprudencia, en este trabajo se intentará valorar cuál puede ser la influencia de Burwell v. Hobby Lobby Stores, Inc. en el debate más general y actual sobre si el derecho a la libertad religiosa de los empresarios puede ser un título legítimo para discriminar en el ámbito de prestación de sus servicios dentro del mercado.
An All Hydrophilic Fluid Diode for Unidirectional Flow in Porous Systems
Authors: Shou Dahua , Fan Jintu
Published: June 2018

A fluid diode that allows fluid flow in one direction but blocks fluid flow in the opposite direction has wide applications including oil recovery, drug delivery, and lab‐on‐a‐chip microfluidics. Many studies are conducted to facilitate directional liquid motion on the solid surface or across thin porous layers. However, the self‐driven one‐way flow inside porous systems still remains a significant challenge. Here, a novel all‐hydrophilic fluid diode (AHFD) made of porous materials with asymmetric pores is reported, which allows capillary flow in a chosen direction. The direction‐dependent flow process and the breakthrough pressure are experimentally and theoretically examined. The proposed AHFD can have many potential applications such as functional protective clothing, microfluidic valve, and oil–water separator, and the idea can be extended to develop other all lyophilic fluid diodes such as oleophilic diode.

High‐performance unipolar n‐type conjugated polymers (CPs) are critical for the development of organic electronics. In the current paper, four “weak donor–strong acceptor” n‐type CPs based on pyridine flanked diketopyrrolopyrrole (PyDPP), namely PPyDPP1‐4FBT, PPyDPP2‐4FBT, PPyDPP1‐4FTVT, and PPyDPP2‐4FTVT, are synthesized via direct arylation polycondensation by using 3,3′,4,4′‐tetrafluoro‐2,2′‐bithiophene (4FBT) or (E)‐1,2‐bis(3,4‐difluorothien‐2‐yl)ethene (4FTVT) as weak donor unit. All four polymers exhibit low‐lying highest occupied molecular orbital (≈ −5.90 eV) and lowest unoccupied molecular orbital energy levels (≈ −3.70 eV). Top‐gate/bottom‐contact organic field‐effect transistors based on all four polymers display unipolar n‐channel characteristics with electron mobility (µe) above 1 cm2 V−1 s−1 in air, and presented linear |ISD|1/2 −VGS plots and weak dependence of the extracted moblity on gate voltage (VGS), indicative of the reliability of the extracted mobility values. Importantly, the devices based on PPyDPP1‐4FBT and PPyDPP2‐4FBT show a pure unipolar n‐channel transistor behavior as revealed by the typical unipolar n‐channel output characteristics and clear off‐regimes in transfer characteristics. Attributed to its high crystallinity and favorable thin film morphology, PPyDPP2‐4FBT shows the highest µe of 2.45 cm2 V−1 s−1, which is among the highest for unipolar n‐type CPs reported to date. This is also the first report for DPP based pure n‐type CPs with µe greater than 1 cm2 V−1 s−1.

In recent years, heterostructures formed in transition metal dichalcogenides (TMDs) have attracted significant attention due to their unique physical properties beyond the individual components. Atomically thin TMD heterostructures, such as MoS2‐WS2, MoS2‐MoSe2, MoS2‐WSe2, and WSe2‐WS2, are synthesized so far via chemical vapor deposition (CVD) method. Engineering the morphology of domains including size and shape, however, still remains challenging. Here, a one‐step CVD strategy on the morphology engineering of MoS2 and WS2 domains within the monolayer MoS2‐WS2 lateral heterostructures through controlling the weight ratio of precursors, MoO3 and WO3, as well as tuning the reaction temperature is reported. Not only can the size ratio in terms of area between WS2 and MoS2 domains be easily controlled from less than 1 to more than 20, but also the overall heterostructure size can be tuned from several to hundreds of micrometers. Intriguingly, the quantum well structure, a WS2 stripe embedded in the MoS2 matrix, is also observed in the as‐synthesized heterostructures, offering opportunities to study quantum confinement effects and quantum well applications. This approach paves the way for the large‐scale fabrication of MoS2‐WS2 lateral heterostructures with controllable domain morphology, and shall be readily extended to morphology engineering of other TMD heterostructures.
