E-atmospherics have motivated an emerging body of research which reports that both virtual layouts and atmospherics encourage consumers to modify their shopping habits. While the literature has analyzed mainly the functional aspect of e-atmospherics, little has been done in terms of linking its characteristics’ to social (co-) creation. This paper focuses on the anatomy of social dimension in relation to e-atmospherics, which includes factors such as the aesthetic design of space, the influence of visual cues, interpretation of shopping as a social activity and meaning of appropriate interactivity. We argue that web designers are social agents who interact within intangible social reference sets, restricted by social standards, value, beliefs, status and duties embedded within their local geographies. We aim to review the current understanding of the importance and voluntary integration of social cues displayed by web designers from a mature market and an emerging market, and provides an analysis based recommendation towards the development of an integrated e-social atmospheric framework. Results report the findings from telephone interviews with an exploratory set of 10 web designers in each country. This allows us to re-interpret the web designers’ reality regarding social E-atmospherics. We contend that by comprehending (before any consumer input) social capital, daily micro practices, habits and routine, deeper understanding of social e-atmospherics preparatory, initial stages and expected functions will be acquired.

Objective: The purpose of this study is to educate allied health professionals and female athletes of the anatomy of the pelvic floor, and the pathology, etiology, and prevalence of stress urinary incontinence in female athletes. Background: Urinary incontinence is not a life-threatening or dangerous condition, but it is socially embarrassing, may cause the individual to remove herself from social situations, and decrease quality of life. While typically associated with parous women who had vaginal delivery, research has shown prevalence of the condition in physically active women of all ages. Stress urinary incontinence has shown to lead to withdrawal from participation in high-impact activities such as gymnastics, aerobics, and running. It may be considered a barrier for life-long athletics participation in women. Description: An in-depth introduction to the cause and origin of stress urinary incontinence including review of the female pelvic floor anatomy and prevalence of stress urinary incontinence in the female athletic population. Clinical Advantages: Athletic trainers and other allied health professionals will develop an understanding of the multiple mechanisms that cause stress urinary incontinence. Clinician competency of the dynamics and mechanism of urinary incontinence prepares the individual to learn diagnostics, prevention, pharmacological intervention, and treatment of this pathology.

The taxonomic delimitation at the species level in plants is not an easy task due to the large polymorphism of plants. In this project we aimed to evaluate three morphotypes (forms) of Cryptanthus zonatus (Vis.) Beer ( Bromeliaceae, Bromelioideae ) described in the literature using fl oral biology and phenology, as well as flo ral morphology and leaf anatomy . These studies were conducted in the Parque Estadual das Dunas de Natal, Rio Grande Norte (RN) and Private Reserve of Natural Patrimony Mata Estrela , in the municipality of Ba í a Form osa. The survey of the phenology of the morphotypes involved monthly specimen observation in the field, during one year. In each visit, we observed the status of flowering and fruiting phenophases of the population of the three forms of C. zonatus . For flo ral biology we sought to evaluate data like: observed floral visitors, nectar volume and concentration, time of anthesis and closing of flowers . Flowers of the three fo rms were collected in the field , analyzed by stereomicroscope, and measurements of the f loral pieces were made with the help of a caliper . Transversal and paradermal sections of the leaves of the three forms were stained and then examined under an optical microscope. Observations of the epidermis under scanning electron microscopy were also conducted. The three m orphotypes could not be sepated based on all evidence investigated. Thus, we conclude that there is not evidences to support the recognition of C. zonatus morphotypes as taxonomic entities, and also that the tools of phenology, anatomy, biology and floral morphology were not useful to delimit these three forms . Yet to characterize better the Flora of Bromeli aceae of RN, the leaf anatomy of Orthophytum disjunctum was also studied. Orthophytum is the sister genus to Cryptanthus and only recently documented in the semiarid of RN. The anatomical comparison between Cryptanthus and Orthophytum allowed the separatio n of both genera based on the arrangement of stomata and thickness of aquiferous parênquima . During the fieldwork, it was still possible to document the first occurrence of Aechmea muricata in RN, inside the Mata Estrela preserve, aiding the understanding of the distribution of the taxon that is currently threatened with extinction.

The new development strategies should operate mainly in the areas of energy efficiency and sustainable agriculture. Thus, the substitution of fossil fuels with biofuels, such as biodiesel, is increasingly on the agenda. The cultivation of oilseed plants for biodiesel production must take place in integrated systems that enable best environmental benefits and are more economically significant. The objectives of this study were to assess the morphological, anatomic, and physiological characteristics of safflower (Carthamus tinctorius L., promising oilseed for biodiesel production) grown in monoculture and intercropping with cowpea bean (Vigna unguiculata L. Walp.); and identify socioeconomic family farmers and verify their acceptance about safflower as an energy crop. The methodology used for the analysis of safflower growth in monoculture and intercropped with beans, were morphoanatomical and histochemical analyzes, made with samples of plants grown in the field in two cropping systems throughout the range of the life cycle of these plants. There were no changes in growth and anatomy of plants, even in the consortium, which is satisfactory to indicate the intercropping system for those crops and can be a good alternative for the family farmer, who may have safflower as a source of income without giving up planting their livelihood. To check the acceptance of safflower by farmers, interviews were made to family farmers by Canudos agrovila in Ceará-Mirim/RN. It was noticed that many of them accept the introduction of safflower as oil crop, although unaware of the species, and that, being more resistant to drought, safflower help in the stability of families who depend on the weather conditions for success their current crops. In general, it is concluded that safflower has features that allows it to be grown in consortium for biodiesel production combined with the production of food, such as cowpea, and can be used enabling better development for family farmers.

Serotonin or 5-hydroxytryptamine (5-HT) is a substance found in many tissues of the body, including the nervous system acting as a neurotransmitter. Within the neuro-axis, the location of the majority of the 5-HT neurons is superimposed with raphe nuclei of the brain stem, in the median line or its vicinity, so that neuronal 5-HT can be considered a marker of the raphe nuclei. Serotonergic neurons are projected to almost all areas of the brain. Studies show the participation of serotonin in regulating the temperature, feeding behavior, sexual behavior, biological rhythms, sleep, locomotor function, learning, among others. The anatomy of these groups has been revised in many species, including mouse, rabbit, cat and primates, but never before in a bat species from South America. This study aimed to characterize the serotonergic clusters in the brain of the bat Artibeus planirostris through immunohistochemistry for serotonin. Seven adult bat males of Artibeus planirostris species (Microchiroptera, Mammalia) were used in this study. The animals were anesthetized, transcardially perfused and their brains were removed. Coronal sections of the frozen brain of bats were obtained in sliding microtome and subjected to immunohistochemistry for 5-HT. Delimit the caudal linear (CLi), dorsal (DR), median (MnR), paramedian (PMnR), pontine (PNR), magnus (MgR), pallidus (RPA) and obscurus (ROb) raphe nucleus, in addition to the groups B9 and rostral and caudal ventrolateral (RVL/CVL). The serotonergic groups of this kind of cheiroptera present morphology and cytoarchitecture relatively similar to that described in rodents and primates, confirming the phylogenetic stability of these cell clusters.

Few symbols of 1950s-1960s America remain as central to our contemporary conception of Cold War culture as the iconic ranch-style suburban home. While the house took center stage in the Nixon/Khrushchev kitchen debates as a symbol of modern efficiency and capitalist values, its popularity depended largely upon its obvious appropriation of vernacular architecture from the 19th century, those California haciendas and Texas dogtrots that dotted the American west. Contractors like William Levitt modernized the historical common houses, hermetically sealing their porous construction, all while using the ranch-style roots of the dwelling to galvanize a myth of an indigenous American culture. At a moment of intense occupational bureaucracy, political uncertainty and atomized social life, the rancher gave a self-identifying white consumer base reason to believe they could master their own plot in the expansive frontier. Only one example of America’s mid-century love affair with commodified vernacular forms, the ranch-style home represents a broad effort on the part of corporate and governmental interest groups to transform the vernacular into a style that expresses a distinctly homogenous vision of American culture. “Other than a Citizen” begins with an anatomy of that transformation, and then turns to the work of four poets who sought to reclaim the vernacular from that process of standardization and use it to countermand the containment-era strategies of Cold War America.
In four chapters, I trace references to common speech and verbal expressivity in the poetry and poetic theory of Charles Olson, Robert Duncan, LeRoi Jones/Amiri Baraka and Gwendolyn Brooks, against the historical backdrop of the Free-Speech Movement and the rise of mass-culture. When poets frame nonliterary speech within the literary page, they encounter the inability of writing to capture the vital ephemerality of verbal expression. Rather than treat this limitation as an impediment, the writers in my study use the poem to dramatize the fugitivity of speech, emphasizing it as a disruptive counterpoint to the technologies of capture. Where critics such as Houston Baker interpret the vernacular strictly in terms of resistance, I take a cue from the poets and argue that the vernacular, rooted etymologically at the intersection of domestic security and enslaved margin, represents a gestalt form, capable at once of establishing centralized power and sparking minor protest. My argument also expands upon Michael North’s exploration of the influence of minstrelsy and regionalism on the development of modernist literary technique in The Dialect of Modernism. As he focuses on writers from the early 20th century, I account for the next generation, whose America was not a culturally inferior collection of immigrants but an imperial power, replete with economic, political and artistic dominance. Instead of settling for an essentially American idiom, the poets in my study saw in the vernacular not phonetic misspellings, slang terminology and fragmented syntax, but the potential to provoke and thereby frame a more ethical mode of social life, straining against the regimentation of citizenship.
My attention to the vernacular argues for an alignment among writers who have been segregated by the assumption that race and aesthetics are mutually exclusive categories. In reading these writers alongside one another, “Other than a Citizen” shows how the avant-garde concepts of projective poetics and composition by field develop out of an interest in black expressivity. Conversely, I trace black radicalism and its emphasis on sociality back to the communalism practiced at the experimental arts college in Black Mountain, North Carolina, where Olson and Duncan taught. In pressing for this connection, my work reveals the racial politics embedded within the speech-based aesthetics of the postwar era, while foregrounding the aesthetic dimension of militant protest.
Not unlike today, the popular rhetoric of the Cold War insists that to be a citizen involves defending one’s status as a rightful member of an exclusionary nation. To be other than a citizen, as the poets in my study make clear, begins with eschewing the false certainty that accompanies categorical nominalization. In promoting a model of mutually dependent participation, these poets lay the groundwork for an alternative model of civic belonging, where volition and reciprocity replace compliance and self-sufficiency. In reading their lines, we become all the more aware of the cracks that run the length of our load-bearing walls.

Primate species typically differ from other mammals in having bony canals that enclose the branches of the internal carotid artery (ICA) as they pass through the middle ear. The presence and relative size of these canals varies among major primate clades. As a result, differences in the anatomy of the canals for the promontorial and stapedial branches of the ICA have been cited as evidence of either haplorhine or strepsirrhine affinities among otherwise enigmatic early fossil euprimates. Here we use micro X-ray computed tomography to compile the largest quantitative dataset on ICA canal sizes. The data suggest greater variation of the ICA canals within some groups than has been previously appreciated. For example, Lepilemur and Avahi differ from most other lemuriforms in having a larger promontorial canal than stapedial canal. Furthermore, various lemurids are intraspecifically variable in relative canal size, with the promontorial canal being larger than the stapedial canal in some individuals but not others. In species where the promontorial artery supplies the brain with blood, the size of the promontorial canal is significantly correlated with endocranial volume (ECV). Among species with alternate routes of encephalic blood supply, the promontorial canal is highly reduced relative to ECV, and correlated with both ECV and cranium size. Ancestral state reconstructions incorporating data from fossils suggest that the last common ancestor of living primates had promontorial and stapedial canals that were similar to each other in size and large relative to ECV. We conclude that the plesiomorphic condition for crown primates is to have a patent promontorial artery supplying the brain and a patent stapedial artery for various non-encephalic structures. This inferred ancestral condition is exhibited by treeshrews and most early fossil euprimates, while extant primates exhibit reduction in one canal or another. The only early fossils deviating from this plesiomorphic condition are Adapis parisiensis with a reduced promontorial canal, and Rooneyia and Mahgarita with reduced stapedial canals.

The article examines developments in the marketisation and privatisation of the English National Health Service, primarily since 1997. It explores the use of competition and contracting out in ancillary services and the levering into public services of private finance for capital developments through the Private Finance Initiative. A substantial part of the article examines the repeated restructuring of the health service as a market in clinical services, initially as an internal market but subsequently as a market increasing opened up to private sector involvement. Some of the implications of market processes for NHS staff and for increased privatisation are discussed. The article examines one episode of popular resistance to these developments, namely the movement of opposition to the 2011 health and social care legislative proposals. The article concludes with a discussion of the implications of these system reforms for the founding principles of the NHS and the sustainability of the service.

El componente satírico es una constante en el teatro de Federico García Lorca, en el que coexisten, en mayor o menor medida, dependiendo de la obra en cuestión, lo cómico y lo serio, ambas vertientes intrínsecas a la sátira. Dicha combinación, así como el innegable aspecto crítico, inherente a la obra lorquiana, identifican a este autor con la figura del satírico. García Lorca lleva a cabo su crítica sirviéndose del humor, que oscila entre lo puramente jocoso y el humor negro, y se manifiesta mediante el empleo de técnicas tradicionales de la sátira, con idéntico propósito al del satírico: degradar a su objeto de ataque suscitando sonrisa o repulsa. Este artículo analiza en clave de sátira Amor de don Perlimplín con Belisa en su jardín, identificando el objeto de ataque de la sátira lorquiana en esta obra y las técnicas satíricas empleadas por su autor.

One of the leading motivations behind the multilingual semantic web is to make resources accessible digitally in an online global multilingual context. Consequently, it is fundamental for knowledge bases to find a way to manage multilingualism and thus be equipped with those procedures for its conceptual modelling. In this context, the goal of this paper is to discuss how common-sense knowledge and cultural knowledge are modelled in a multilingual framework. More particularly, multilingualism and conceptual modelling are dealt with from the perspective of FunGramKB, a lexico-conceptual knowledge base for natural language understanding. This project argues for a clear division between the lexical and the conceptual dimensions of knowledge. Moreover, the conceptual layer is organized into three modules, which result from a strong commitment towards capturing semantic knowledge (Ontology), procedural knowledge (Cognicon) and episodic knowledge (Onomasticon). Cultural mismatches are discussed and formally represented at the three conceptual levels of FunGramKB.

This paper presents an eight-firm study, conducted from the service-dominant logic perspective, which makes a contribution regarding knowledge of the anatomy of value propositions and service innovation. The paper suggests that value propositions are configurations of several different practices and resources. The paper finds that ten common practices, organized in three main aggregates, constitute and fulfill value propositions: i.e. provision practices, representational practices, and management and organizational practices. Moreover, the paper suggests that service innovation can be equated with the creation of new value propositions by means of developing existing or creating new practices and/or resources, or by means of integrating practices and resources in new ways. It identifies four types of service innovation (adaptation, resource-based innovation, practice-based innovation, and combinative innovation) and three types of service innovation processes (practice-based, resource-based, and combinative). The key managerial insight provided by the paper is that service innovation must be conducted and value propositions must be evaluated from the perspective of the customers’ value creation, the service that the customer experiences. Successful service innovation is not only contingent on having the right resources, established methods and practices for integrating these resources into attractive value propositions are also needed.

Introdução: O objetivo da terapia endodôntica é eliminar a infeção presente nos canais radiculares e prevenir a reinfeção dos mesmos, criando assim as condições para a manutenção da peça dentária em função e livre de patologia pulpar ou peri-apical. A complexa anatomia dos canais faz com que seja impossível uma limpeza completa dos mesmos. Para se conseguir um bom resultado clínico é de extrema importância utilizarmos técnicas e procedimentos que visem uma utilização combinada de instrumentação mecânica e desinfeção com soluções de irrigação. Objetivo: Revisão bibliográfica sobre sistemas auxiliares de desinfeção em Endodontia, abordando as suas principais vantagens e limitações e apresentando estudos que provam a sua importância para o sucesso do tratamento endodôntico. Materiais e métodos: Realizou-se uma pesquisa eletrónica nos principais motores de busca online tais como PubMed, B-On, Scielo e Science Direct e em livros científicos sobre a temática, utilizando palavras-chave em inglês tais como “irrigation techniques”, “sonic irrigation”, “EndoVac”, “EDTA”, “hypoclorite sodium”, “passive ultrasonic irrigation”, “apical negative pressure irrigation”, “root canal irrigation”, “EndoAtivator”, e ainda alguns termos em português tais como “insucesso em endodontia”, “hipoclorito de sódio” “ácido cítrico” e “irrigação sónica e ultrasónica”. Da pesquisa efectuada entre Junho e Novembro de 2015 e cujo critério de inclusão foram artigos datados de 2001 a 2015, escolheu-se 65 artigos em inglês, 4 em português e 1 em espanhol, dos quais se utilizaram 44 artigos. Além dos artigos analisou-se 2 livros, dos quais se utilizou 1. Resultados: Os artigos analisados apresentam como principais resultados que a combinação de instrumentação mecânica e a irrigação reduz mas não elimina totalmente as bactérias. Até à data não existem soluções de irrigação ideais. Têm-se desenvolvido técnicas capazes de combater as dificuldades encontradas e aumentar as potencialidades da irrigação, cada uma apresentando suas vantagens e desvantagens. Dos resultados constatados, a literatura científica aparenta reconhecer o Sistema EndoVac como o melhor em termos de biossegurança e o sistema de irrigação ultrasónica passiva como o melhor em termos de desinfecção e limpeza. Conclusão: Uma combinação de soluções com uma sequência específica é aparentemente necessária para atingir o sucesso endodôntico, bem como uma escolha adequada da técnica. As novas técnicas desenvolvidas tais como a ativação dinâmica manual, irrigação ultrasónica passiva, ativação sónica e sistemas de pressão apical negativa apresentam melhores resultados quando associados a irrigantes adequados como o hipoclorito, EDTA, ácido cítrico, clorohexidina e álcool. No entanto, concluiu-se que mais investigação é necessária para melhorar o sucesso do tratamento endodôntico não-cirúrgico.

Introdução: As neoplasias do espaço parafaríngeo são raras, representando apenas 0,5% dos tumores da cabeça e pescoço. A maioria são benignas, mas uma ampla variedade de patologias benignas e malignas podem ser encontradas neste espaço, o que cria desafios complexos de diagnóstico e tratamento. Objetivo: Descrever e analisar uma série de casos de neoplasias primárias do espaço parafaríngeo tratadas no Instituto Português de Oncologia de Lisboa Francisco Gentil (IPOLFG). Material e métodos: Estudo retrospetivo, com recolha e análise dos dados dos processos clínicos de tumores primários do espaço parafaríngeo, que foram diagnosticados ou referenciados ao IPOLFG entre 1 de Janeiro de 2003 e 31 de Dezembro de 2013. Resultados: Foram incluídos 38 doentes. A idade mediana foi de 52 anos (Âmbito Interquartil: 40-63 anos). Dez (26,3%) doentes eram assintomáticos. O sintoma mais comum à apresentação foi a sensação de corpo estranho orofaríngeo (23,7%) e o achado mais frequente foi um abaulamento orofaríngeo (78,4%). Todos os doentes fizeram exames de imagem pré-operatórios: 94,7% tomografia computorizada e 68,4% ressonância magnética. A citologia aspirativa foi realizada em 39,5%. 31 tumores eram benignos (81,6%), sendo os mais frequentes os adenomas pleomórficos (58,1%). 7 eram malignos (18,4%), com os carcinomas exadenomas pleomórficos (28,6%) e os linfomas (28,6%) sendo os mais comuns. 36 doentes (94,7%) foram submetidos a tratamento cirúrgico primário; os outros 2 doentes (5,3%) receberam tratamento não cirúrgico, com quimioterapia e quimioradioterapia, respectivamente. A abordagem cervical foi a mais utilizada (80%). A mandibulotomia foi necessária em apenas 5,7%. A complicação mais frequente foi a neuropatia de pares cranianos de novo, identificada em 22,2%. Destes, 75% foram sequela da resseção de tumores neurogénicos. Todas as neuropatias que resultaram da resseção de tumores não neurogénicos foram transitórias. O follow-up mediano foi de 6,5 anos. A taxa de recorrência foi de 13,5%. Conclusões: Os tumores do espaço parafaríngeo requerem um elevado índice de suspeição para serem diagnosticados num estadio precoce. A resseção cirúrgica completa é o principal tratamento. A abordagem cirúrgica deve ser selecionada caso a caso, mas a cervical fornece um excelente acesso à maioria dos tumores deste espaço

Sugarcane (Saccharum spp.) is a plant from Poaceae family that has an impressive ability to accumulate sucrose in the stalk, making it a significant component of the economy of many countries. About 100 countries produce sugarcane in an area of 22 million hectares worldwide. For this reason, many studies have been done using sugarcane as a plant model in order to improve production. A change in gravity may be one kind of abiotic stress, since it generates rapid responses after stimulation. In this work we decided to investigate the possible morphophysiological, biochemical and molecular changes resulting from microgravity. Here, we present the contributions of an experiment where sugarcane plants were submitted to microgravity flight using a vehicle VSB-30, a sounding rocket developed by Aeronautics and Space Institute teams, in cooperation with the German Space Agency. Sugarcane plants with 10 days older were submitted to a period of six minutes of microgravity using the VSB-30 rocket. The morphophysiological analyses of roots and leaves showed that plants submitted to the flight showed changes in the conduction tissues, irregular pattern of arrangement of vascular bundles and thickening of the cell walls, among other anatomical changes that indicate that the morphology of the plants was substantially influenced by gravitational stimulation, besides the accumulation of hydrogen peroxide, an important signaling molecule in stress conditions. We carried out RNA extraction and sequencing using Illumina platform. Plants subjected to microgravity also showed changes in enzyme activity. It was observed an increased in superoxide dismutase activity in leaves and a decreased in its activity in roots as well as for ascorbate peroxidase activity. Thus, it was concluded that the changes in gravity were perceived by plants, and that microgravity environment triggered changes associated with a reactive oxygen specie signaling process. This work has helped the understanding of how the gravity affects the structural organization of the plants, by comparing the anatomy of plants subjected to microgravity and plants grown in 1g gravity
