This study aimed to identify the constructs related to customer experience that underpin e-commerce, as well as their interconnections, to develop a comprehensive conceptual model based on theories-in-use. A quantitative approach was employed through a survey of 441 respondents. Data analysis was conducted using partial least squares structural equation modeling. The research findings revealed that there are a total of 11 constructs: customer experience, customer satisfaction, customer loyalty, word-of-mouth, trust, perceived risk, security and privacy, web content, perceived price, perceived value, and service quality. Furthermore, twelve relationships were established between these constructs, which led to the development of a holistic conceptual model. The identified constructs and the relationships between them are hierarchized, which has practical implications for businesses. It allows them to concentrate on operational activities and formulate and implement strategies that are valued by consumers and supported by empirical evidence. The originality and value of this research lie in the conception and development of a comprehensive e-commerce model, which includes eleven constructs and twelve relationships. It also highlights the pivotal role of the customer experience.

Organizations assume a key role in the goal of achieving sustainable development and are influential elements on the path to sustainability. Allied with competitiveness, today, there is also a strategy based on sustainability, anchored in the concept of responsibility, minimizing the potential negative effects of our actions through innovative products, services, processes, and models. Measuring and monitoring these efforts is currently a challenge for organizations. This study adopts a mixed methods approach to address this challenge and identifies 13 tools and 16 dimensions that are central elements in the process of measuring and monitoring sustainable innovation. The findings indicate that the dimensions related to social and governance components are the most relevant in sustainable innovation, while inclusion and entrepreneurship are dimensions that are not highly valued by these tools.

El artículo presenta el escenario político que dibujaron las elecciones presidenciales de Paraguay en mayo de 2023 con relación a las siguientes dimensiones: los partidos políticos, el sistema electoral y el impacto del resultado electoral en el ámbito político, económico e internacional. Para ello comienza realizando una caracterización del orden político, desde el inicio de la transición a la democracia, que permite marcar algunos hitos de cambio y continuidad. Parte de la hipótesis de que, si bien la partidocracia paraguaya se ha mantenido a lo largo de más de dos siglos, hay procesos de transformación generales y locales que han afectado la vida interna de los partidos y la representación política y han dado lugar al surgimiento de rasgos singulares de terceras fuerzas.

The concept of sustainable fashion is becoming more relevant in today’s society. The purpose of this research is to identify the determinants of the purchase intention of sustainable fashion, and the relationship between price and the purchase of sustainable fashion. A questionnaire was administered, which made it possible to define the concept of sustainable fashion, to use PLS-SEM to identify the determinants, and to apply linear regression models and t-tests of two independent samples (two-tailed test). The concept of sustainable fashion comprises the dimensions of manufacturing with a reduced environmental impact, consuming second-hand fashion products, manufacturing in an environmentally friendly way, reusing fashion products, manufacturing to last longer, manufacturing according to fair trade principles, using recycled materials, and manufacturing from organic materials. The PLS-SEM results show that purchase intention is determined by consumer knowledge, environmental beliefs, and willingness to pay more. The research also revealed that there is a non-linear (quadratic or exponential) relationship between the price of the product and the price increase that consumers are willing to pay and that they value the dimensions of sustainable fashion differently. The purchase intention determinants of consumers and non-consumers of sustainable fashion are identical, yet the dimensions of sustainable fashion are valued differently by each group.

Astrocytes are ubiquitous in the brain and spinal cord and display a complex morphology important for the local interactions with neighboring cells, resulting in the modulation of circuit function. Thus, studies focusing on astrocyte physiology in the healthy and diseased brain generally present analyses of astrocytic structure. The labeling method used to visualize the astrocytic structure defines the morphological level to observe and may vary depending on the anatomical sub-regions. The method choice may significantly affect our understanding of their structural diversity. The main goal of this work was to identify a straightforward and efficient protocol for labeling and reconstructing a detailed astrocytic structure to apply and validate in different brain tissue preparations across laboratories. For that, we explored different tissue processing protocols before GFAP labeling to determine the most effective method for reconstructing astrocytic backbones in the mouse hippocampus. Our results show that the reconstruction of astrocytic structure in vibratome sections labeled by free-floating immunofluorescence protocol provides a more practical method to achieve a higher level of detail and arbor complexity in astrocyte backbone reconstruction. Free-floating immunofluorescence labeling is the most reliable method for obtaining better antibody penetration and more detailed astrocyte structure. Finally, we also show that introducing an antigen retrieval step appears useful for visualizing more complete structural details.

Através de diferentes perspectivas, o presente trabalho pretende analisar o filme Museum Town (Jennifer Trainer, 2019) e o modo como este dá conta do processo de revitalização do espaço que originou MASS MoCA. Para tal, o artigo segue três linhas orientadoras: 1) a história de North-Adams que 2) se cruza com a história de MASS MoCA – e que vai sendo apresentada através de imagens de arquivo e de entrevistas –, e 3) a construção e instalação de “Until”, de Nick Cave. Estas permitir-nos-ão tentar entender qual a potencialidade e papel de um projecto como o MASS MoCA, enquanto nos ajudarão igualmente a compreender a relação deste mesmo projecto com a pequena cidade que o acolhe, North-Adams, MA.

Introduction: The COVID-19 pandemic has imposed an unprecedented burden on healthcare systems worldwide, changing the profile of interventional cardiology activity. Objectives: To quantify and compare the number of percutaneous coronary interventions (PCIs) performed for acute and chronic coronary syndromes during the first COVID-19 outbreak with the corresponding period in previous years. Methods: Data on PCI from the prospective multicenter Portuguese Registry on Interventional Cardiology (RNCI) were used to analyze changes in PCI for ST-elevation myocardial infarction (STEMI), non-ST-elevation acute coronary syndromes (NSTE-ACS) and chronic coronary syndromes (CCS). The number of PCIs performed during the initial period of the COVID-19 outbreak in Portugal, from March 1 to May 2, 2020, was compared with the mean frequency of PCIs performed during the corresponding period in the previous three years (2017–2019). Results: The total number of PCIs procedures was significantly decreased during the initial COVID-19 outbreak in Portugal (−36%, p

This research aims to study Celebrity Endorsement in the context of Social Media when practiced by Sports Celebrities and its influence on Purchase Intention. Four dimensions were studied: Word-of-Mouth, Brand Image, Brand Trust and Brand Attitude. Relating these variables, we intended to answer the following questions: will a consumer be influenced by a Sports Celebrity that he follows, to buy something from a brand that he supports? Will the brand be valued in its components from this Celebrity Endorsement? The methodology used a structural equation model and the results were analyzed using SmartPLS software, which verified all the model assumptions. Therefore, celebrity endorsement impacts brand image, word of mouth, brand attitude, and brand trust. Further, it directly affects Purchase intention, but the impact of Brand Attitude on Purchase Intention was not verified in this research. The effectiveness of Celebrity Endorsement was verified in context.

O presente trabalho visa analisar a presença de possíveis inconstitucionalidades, ilegalidades e retrocessos no Decreto nº 10.520/2020, tomando por base o estudo da evolução histórica do direito à educação da pessoa com deficiência. A educação inclusiva é a que é prestada na rede regular de ensino. Nesse aspecto, referido ato normativo regulamentar desvirtua-se completamente das diretrizes internacionais, constitucionais e legais atinentes ao tema, permitindo o retorno da política educacional segregacionista de outrora, criando escolas especiais para os estudantes que não se “adequam” ao sistema regular de ensino. O Supremo Tribunal Federal já teve oportunidade de decidir sobre a matéria, entendendo pela primazia do ensino regular como fomento à educação inclusiva. Em decisão liminar referendada pelo Plenário, na ADI nº 6.590, suspendeu temporariamente a eficácia do Decreto nº 10.520/2020 até a deliberação final pela Corte. Esta pesquisa conclui, identicamente, que referido ato normativo incorre em inconstitucionalidade e ilegalidade. Os métodos utilizados foram o dedutivo e histórico, a partir da revisão de doutrinas (nacionais e estrangeiras), diplomas normativos (constitucionais, legais e infralegais), além da consulta e pesquisa de julgados

Os depósitos cenozóicos ocupam grandes áreas do território brasileiro e são pouco conhecidos e pesquisados. A Formação Barreiras é uma das unidades sedimentares Cenozóicas(Neógeno) mais importantes do Brasil e apresentam relevo de formas tabulares, dissecadas em vales profundos com declives acentuados. Esse trabalho propõe uma metodologia semiautomática de mapeamento desses depósitos, em escala detalhada, empregando Modelos Digitais de Superfície obtidos de pares estereoscópicos de imagens de satélite de alta resolução. A metodologia consistiu em: (1) geração dos MDS e ortoimagens, usando modelo empírico de funções racionais e coeficientes RPC; (2) avaliação da precisão altimétrica e planimétrica (3) preparação dos MDS; (4) análises de terreno e geração de mapas, a partir da combinação e interpretação de variáveismorfométricas; e (5) avaliação qualitativa e quantitativa dos mapas, por meio de álgebra de mapas. Os limites da Formação Barreiras foram identificados combinando as variáveis: altitude, declividade, curvatura e índices: TRI, MRVBF e MRRTF. Os resultados do mapeamento apresentaram 83% de correlação. Do percentual de áreas não correlacionadas, 9% apresentaram falsos negativos e coincidiram com as áreas cuja morfologia foi alterada devido ao soerguimento por movimentos tectônicos. A metodologia proposta mostrou-se fundamental para redução do tempo na geração de mapas em escala de detalhe.

Social shopping has been increasing its impact on e-commerce, motivating companies to rethink their product or service marketing strategies. Also, academics from various countries, aware of this growth, seek, through their scientific publications in various journals, to present studies that allow them to identify elements that contribute to the consolidation of the social shopping concept. Bearing this reality in mind, this study, supported by a bibliometric analysis on social shopping and based on articles published in the last 20 years, seeks to analyze the evolution of scientific research, to identify the most influential scientific publications (for topics related to social shopping) and to detect research opportunities in social shopping, with 39% of scientific publication occurring in the years 2020 to 2022. The study also presents themes that are associated with social shopping, highlighting COVID-19, consumer behavior and online shopping, aspects that companies should consider in their e-commerce strategy. The study also identifies the most influential scientific publications for topics related to social shopping and for detecting research opportunities in social shopping, supported in six clusters.

Frankenweenie (2012) is amongst the most personal films directed by Tim Burton because it reflects the director’s visual aesthetics and thematic obsessions, while also being a composite of different bodies: monstrous, anomalous, literary and cinematic. In this sense, the film serves as a container for Burton’s art and creative view. Basing our analysis on research developed by Salisbury (2000) and Weinstock (2013), this study looks at ideas of monstrosity (Mittman, 2016) and the monstrous bodies portrayed in the film, which are connected with the other “bodies” the director creates and reanimates. Victor and Sparky, but also the film itself, are constructions deriving from literature and cinema and, consequently, can be viewed as bodies produced from a palimpsest of ideas and concepts. Thus, the purpose of this essay is to look into the different bodies explored in the film, while trying to understand how the director has contributed to the ongoing discussion of what it means to be monstrous and, therefore, what it means to be human.

This paper aims to study the effect of corporate social responsibility (CSR) on brand image and brand equity and its impact on consumer satisfaction. The study follows a quantitative methodology, using the implementation of an online questionnaire distributed to people who bought, during the pandemic, a product that used a CSR action. Subsequently, data were analyzed through Smart PLS, following the Structural Equation Model. It was possible to conclude that the CSR initiatives positively affect consumer satisfaction through the mediating effect of brand image and brand equity. Further, brand image and brand equity improve when companies use CSR initiatives, and, despite what previous research has concluded, consumer satisfaction is not affected directly when CSR initiatives are used. This research has also showed that CSR’s impact on brand image is higher for men, and CSR initiatives’ impact on brand equity is also higher for regular purchase consumers.

A leishmaniose canina visceral é uma zoonose que possui grande repercussão na saúde animal e humana, cujo agente etiológico são os protozoários do gênero Leishmania sp. O objetivo do estudo consiste em realizar uma revisão sobre os aspectos importantes da doença, como agente etiológico, transmissão e patogenia, sinais clínicos, diagnóstico, tratamento, prevenção e controle, para acrescentar informações no âmbito da clínica médica de pequenos animais.

A segunda década do século XXI assiste uma disputa de que há muito se pensava resolvida: a oposição entre regimes constitucionais democráticos e autocráticos enquanto possibilidades para a solução dos dilemas econômicos e sociais do Ocidente. Com nova tessitura institucional e política, diferente da que existira antes, o fenômeno desafia estudiosos para sua compreensão e mesmo denominação. Constitucionalismo abusivo, Democracias iliberais ou Populismos são alguns desses rótulos que exprimem o vivenciado. Em um dos quadrantes do mundo ocidental, as organizações constitucionais da América Latina se deparam com a mesma convergência desafiadora, ainda que ambientada a partir de suas idiossincrasias: fruto de um empreendimento passado de tradição europeia que se lançou sobre povos autóctones com propósito colonizador; projeto de construção soberana de nações politicamente marginalizadas; desafio de integração global e de superação de economias marcadamente dependentes; dilema de inclusão social e de superação de desigualdades internas históricas. A obra de Roberto Gargarella, trazida ao prelo em 2013, mas ainda não traduzida para o português, mesmo que não enfrente diretamente a questão da “deterioração interna” das Democracias, é um útil instrumento hermenêutico para a reflexão sobre as organizações constitucionais construídas em 200 (duzentos) anos de historicidade latino-americana. Sobretudo para o enfrentamento dos graves perigos às Democracias, em especial, para as que se constroem no continente, dada a gama de outras dificuldades enunciadas acima e que devem ser identicamente enfrentadas.

The panoply of symbology and narratives that surround the grape, right from ancestral times, include dichotomous contours of both the sacred and profane, and distinguishes the final product, wine, from any other agricultural product. It can therefore be said that grape and wine production carry a multiplicity of historical meanings which convey the very characteristics and richness of the land and the soils of its origin. In this context, following an initial historical review of grape and wine from its ancient origins in Anatolia until modern Turkey, this paper focuses on Ankara’s heritage of vineyard landscapes, grapes, and wine production while providing a critical assessment of its overall legacy. The aim is therefore to not only link together the vine plant and the soil, but also the people and their territory. Unfortunately, the heritage of wine production is fading away. While the Turkish word for the vineyard is bağ, which also means “connection,” the connection between the city and its legacy is weakening. This research constructs a socio-cultural history of wine production which combine, with an emphasis on Anatolia, sociological/ ethnographic and urbanist approaches to demonstrate the importance of grape and wine for civilizations. By referring to the geography of Anatolia and its suitability for grape production, the research also investigates the spatial features of that history, with a particular focus on Ankara. The viticulture of the city seventy years ago, when it was surrounded by vineyards, is now no more, although the living landscapes (vineyards and houses), wine production and education facilities (Atatürk Forest Farm, Faculty of Agriculture and wineries) and the towns (Kalecik, Akyurt) still remain. The main objective of this study is to contribute to the history of Ankara, which has never been specifically studied through the approach described above, thus simultaneously shedding light on the socio-cultural and spatial history of the region itself. To summarize the results obtained from the research, it can be seen that a nexus of actors, networks and policies exist between the periods of enrichment, and the destruction, of the legacy of grape in Ankara. A city that was once called Engürü (the Persian word for grape) is no longer worthy of that name, and the city is symbolic of the current decline of grape and wine production in Turkey, as well as the degrading perception of the industry in the country.

Social media assume increasing importance in the light of the evolution of the digitalization processes in the economy. In the context of global change, Small and Medium Enterprises (SMEs) look to social networks as a way to prosper and promote their businesses at a lower cost. This study aims to explore the state of development of social media among Portuguese SMEs through the characterization of their adoption process, benefits, good practices, and challenges. The findings reveal that more than 75% of Portuguese SMEs already use social media in their marketing activities. This online presence allows them to have a new communication channel that supports their innovation processes. The role of analyzing customer feedback and establishing contact with most loyal customers was mentioned as good practices. Finally, Portuguese SMEs that do not use social networks highlight their low interest in this digital communication channel.

Introduction: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score. Methods: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded. Linear and logistic regression analysis were used to identify predictors of success. A score to predict success was created and its accuracy was measured by receiver operating curve analysis. Results: A total of 377 interventions were performed (334 patients, age 68±11 years, 75% male). The success rate was 65% per patient and 60% per procedure. Predictors of success in univariate analysis were absence of active smoking (OR 2.02, 95% CI 1.243-3.29; p=0.005), presence of tapered stump (OR 5.2, 95% CI 2.7-10.2; p8 with high probability (95%). Conclusion: In our sample only anatomical characteristics were predictors of success. The creation of a score to predict success, with good accuracy, may enable selection of cases that can be treated by any operator, those in which a dedicated operator will be desirable, and those with an extremely low probability of success, which should be considered individually for conservative management, surgical revascularization or PCI by a team experienced in CTO. Resumo: Introdução: Selecionar os doentes para angioplastia (ICP) de oclusão crónica (CTO) é crucial para o êxito do procedimento. Pretende-se identificar preditores independentes de sucesso na ICP de CTOs para criação de um score de boa acuidade. Métodos: Registo observacional unicêntrico de ICP em CTOs. Registaram-se características demográficas, clínicas e características anatómicas das lesões. Identificados preditores de sucesso por regressão linear e logística, posterior construção de score preditor de sucesso cuja acuidade foi aferida por análise com curva ROC. Resultados: Realizaram-se 377 intervenções (334 doentes, 68±11 anos, 75% homens); taxa de sucesso por doente: 65%, por procedimento: 60%. Em análise univariada, foram preditores de sucesso: ausência de tabagismo (OR 2,02; 95%CI 1,243–3,29; p=0,005); coto afilado (C) (OR 5,2; 95%CI 2,7–10,2; p8 a probabilidade elevada (95%). Conclusão: Nesta amostra, apenas as características anatómicas foram preditoras de sucesso. Um score de sucesso poderá permitir selecionar casos passíveis de intervenção por qualquer operador, aqueles que requerem operador dedicado a oclusões e aqueles com probabilidade de sucesso reduzida onde se considere individualmente manejo conservador, revascularização cirúrgica ou ICP por equipa experiente/dedicada.

Abstract Oxaliplatin-based chemotherapy has been widely used to treat colorectal cancer. Here, we report a case of a 71-year-old man, former smoker (40 pack-years), with no history of relevant exposures such as occupational, environmental or drug exposure. The patient developed acute partial respiratory insufficiency concomitant with the eighth cycle of adjuvant chemotherapy with oxaliplatin and capecitabine for stage IIIA colorectal adenocarcinoma. After the exclusion of other causes, namely pulmonary thromboembolism, high-resolution chest computed tomography (CT) showed a usual interstitial pneumonia (UIP) pattern. After the discussion at the multidisciplinary meeting on interstitial lung diseases and considering the temporal association between clinical and imaging findings and chemotherapy treatment, along with exclusion of other potential causes, the most likely hypothesis was pulmonary fibrosis secondary to oxaliplatin. A literature review on this scope was also performed. We conclude that pulmonary fibrosis is a rare complication of oxaliplatin, but with the widespread use of oxaliplatin combinations in colorectal cancer, active assessment for interstitial lung disease is recommended.

Homodyne demodulation is a convenient technique for signal detection in interferometric sensors. The demodulation process is typically developed using analog circuits. However, to improve the performance of the demodulator, a digital system must be employed. In this study, we developed an optical fiber sensor by combining: (a) a Michelson interferometer, (b) a micro-electro-mechanical system (MEMS) device, and (c) a field-programmable gate array (FPGA)-based interrogator. Signal processing was integrated into the FPGA-embedded system. The homodyne demodulation algorithm was implemented with hardware modules developed in the hardware description language (HDL) to provide a portable, low-cost, and scalable digital system. The present study successfully demonstrates the development and validation of an FPGA-based interrogator capable of processing interferograms through a homodyne demodulation scheme. The experimental results reveal proper displacement measurements of the proof-mass MEMS and the low amount of hardware resources used. The displacement measurements obtained from the system matched those obtained from a certified characterization system. As the system can be easily reconfigured to the required measured signal, a similar measurement methodology can be developed using other demodulation schemes and optical fiber sensors.

The amphisbaenian Leposternon octostegum (Duméril, 1851) is redescribed based on newly collected material from the state of Bahia, Brazil. Species validity was confirmed, and comparisons made to other Leposternon species and to the scarce literature available on Leposternon octostegum taxonomy. Aspects of meristic annuli methodology are reviewed, and nomenclatural adjustments for some scales are proposed. To place this information in its taxonomic context, a species identification key for the Brazilian species of the genus Leposternon is provided. The present redescription contributes to a better understanding of Amphisbaenia taxonomy, thus also enabling the design of more adequate conservation and management strategies for the species belonging to this group.

The projects funded under the European Horizon 2020 program have responded to the challenges facing small enterprises and have provided a framework for different actors (e.g., universities, R&D centers, SMEs) to collaborate and find innovative approaches to address the challenges of digital transformation. This study conducts a bibliometric analysis of the scientific production supported by this project, between 2014 and 2021, evaluating 114 projects, which have associated 2312 scientific production items and 1460 deliverables. The results demonstrate that scientific production is mostly carried out collaboratively with project partners and is mainly published in peer-reviewed journals. The research demonstrates that resources, such as Horizon 2020, provide a useful adjunct to other databases as a basis for bibliometric and related analyses.

Passada num ambiente distópico, Judge Dredd é uma obra de HQ que centra a sua atenção em temas como o totalitarismo, autoritarismo, a violência ou os perigos da tecnologia. O estudo aqui apresentado procura olhar para a obra de Wagner e Ezquerra explorando, em primeiro lugar, o universo da personagem Dredd, para depois analisar as duas adaptações cinematográficas (1995, 2012) que se lhe seguiram e a forma como estas refletem as ansiedades do seu tempo. Desse modo, o objetivo deste estudo é perceber como Dredd, mas também Mega-City One (local onde se passa a narrativa), têm sido usados enquanto reflexo da contemporaneidade e como forma de denunciar os potenciais perigos de um (futuro) mundo distópico. Palavras-chave: Juiz Dredd. Distopia. Totalitarismo. Histórias em quadrinhos. Cinema.

Online gambling is a form of gambling. Its direct ban or lack of regulation leads to loss of revenue. These are used to support the social functions of the state. In this research we analyse the estimates about the relevance of online gambling, taking as a reference the European Union where online gambling activity is allowed. These data are compared with estimates for Brazil that does not allow online gambling. Some principles on game regulation are proposed, which can serve the Brazilian case, based on the experience of European and world regulation.

A soberania historicamente se especializou em várias funções para diferentes órgãos. Os Tribunais Constitucionais surgem no século XX como uma função especializada. Eles têm jurisdição para proteger a Constituição. Seu modelo se espalhou para os países europeus, com uma organização diferente da estrutura do Poder Judiciário. Existem diferenças entre eles em questões como a competência das Cortes e a nomeação, permanência no cargo e independência de seus juízes. A Constituição Federal de 1988 criou o Supremo Tribunal Federal como um uma Corte de Justiça. No entanto, concedeu-lhe parte dos poderes de um Tribunal Constitucional. Emendas à Constituição Federal, leis promulgadas e a jurisprudência da Corte também estabeleceram uma jurisdição extra. Mas o Supremo Tribunal Federal persiste estruturalmente ainda como uma Corte Suprema. Essa situação política e constitucional única cria crises entre as três funções políticas de um sistema presidencial de governo. É necessário discutir uma solução, e a discussão recomenda o estabelecimento de um Tribunal Constitucional. Essa mudança requer, entre outros tópicos, o debate sobre o processo de nomeação de seus juízes. Existem diferentes formas de nomeação em todo o mundo. O objetivo deste artigo é, do ponto de vista comparativo, iniciar o debate sobre o modelo de nomeação mais adequado para o nosso sistema político, bem como sobre as necessidades relacionadas à criação de um Tribunal Constitucional.

O presente artigo visa analisar a decisão proferida na ADI n° 4.815/DF pelo Supremo Tribunal Federal, em que restou estabelecida a desnecessidade de autorização prévia do biografado e de coadjuvantes para a publicação de biografias. Em verdade, por trás da decisão, há o conflito entre Direitos Fundamentais: o Direito à Intimidade e o Direito à Informação, enquanto princípios constitucionais, colidem diante de situações concretas em que ambos podem ser legitimamente exercidos, e demandam a ponderação judiciária para a resolução do conflito, visto que a nenhum deles pode ser atribuído o caráter de absoluto. Assim, a presente pesquisa se propõe a analisar se tal decisão observou o núcleo essencial do Direito à Intimidade ou se o Direito à Informação foi realizado em sua forma ótima, bem como se a dignidade da pessoa humana, princípio guia de todo o ordenamento jurídico, foi respeitada quando da decisão. Para tanto, utilizando-se principalmente da pesquisa bibliográfica e guiando-se pelo método dedutivo, será analisada a evolução constitucional brasileira com relação à tutela dos direitos em colisão, a forma de resolução de conflitos entre Direitos Fundamentais pela doutrina e pelo órgão de cúpula do judiciário brasileiro, e a ADI n° 4.815/DF sob a ótica da dignidade da pessoa humana.

Realizado por Heidi Ewing e Rachel Grady, Detropiaé um documentário que explora as ruínas modernas de Detroit alguns anos depois da crise económica mundial de 2008 que afectou várias cidades por todo o mundo. Longe do período áureo da “Motor City”, Detroit é reproduzida em Detropiacomo uma cidade que já foi em tempos uma cidade global, mas é agora retrato da impossibilidade (contemporânea) do sonho americano. O documentário percorre espaços outrora grandiosos, mostrando histórias de ausência e presença, mas também de crença, graças aos seus habitantes. Enquanto uns preferem fugir, outros pretendem permanecer, mostrando que o espaço urbano ainda pode ser renovado. O presente artigo pretende analisar a forma como a cidade é vista em Detropia, as suas múltiplas visões, possibilidades e contradições recorrendo a textos que exploram a relação entre cidade, cinema e ruínas modernas. Directed by Heidi Ewing and Rachel Grady, Detropia is a documentary that explores Detroit’s modern ruins some years after the economic recession in 2008 that affected several cities around the world. Far from its “Golden Age”, Detroit is portrayed in Detropiaas a city that was once booming, but now embodies the impossibility of the (contemporary) American Dream. Thus, the documentary films spaces that used to be magnificent, but are now representations of absence and presence, but also of faith because of its inhabitants. While some prefer to leave, others choose to stay in an attempt to recover the city by any means necessary. This article looks at how Detropiaexplores the city of Detroit, its multiple visions, possibilities and contradictions by employing theoretical approaches that analyze the relationship between city, cinema and modern ruins.

Bilateral diaphragm paralysis due to bilateral isolated phrenic neuropathy (BIPN) is a very rare cause of unexplained respiratory failure. We present a 65-year-old patient with no relevant previous medical history who presented in the Pulmonology Clinic with mMRC1 dyspnoea and orthopnoea. After the medical work-up, diaphragmatic paresis was diagnosed. Inspiratory muscle training resulted in mild symptomatic improvement and treatment with noninvasive mechanical ventilation (NIV) was initiated. This condition is generally chronic and has a poorer prognosis, compared to other cases of phrenic nerve involvement. In this case, NIV restored near-normal daily function.

Electrical discharge machining (EDM) involves the generation of micro-plasmas subjected to high temperature and pressure to promote the material removal. Hence, to understand the material removal mechanism it is of great importance the knowledge of the interaction plasma-solid. Knowing how physical and chemical properties of materials affect heat transfer at the electrode surface, how this eventually affects electrical properties of the plasma channel over the discharge time are key issues to achieve a better understanding of this machining technology. This research attempts to provide some answers to these issues by means of single plasma discharge tests under laboratory-controlled conditions carried out on pure and low-alloyed materials in favour of comprehensiveness and forthcoming numerical modelling. These results demonstrate that material eroded volume is correlated with process operating parameters and that crater morphology has presented a more regular shape in pure metals than in engineering materials. The machinability index of the materials under study has been determined by calculations of the eroded volume and electrical power measures. Further to the low predictability of the models presented in literature, it was also proposed a basic conceptual model referring to the morphology of the eroded craters.

Abstract Background Vascular homeostasis is ensured by a dynamic interplay involving the endothelium, the platelets and the coagulation system. Thus, the vascular safety of particulate materials must address this integrated system, an approach that has been largely neglected. This work analysed the effects of commercial hydroxyapatite (HA) particles in blood compatibility and in endothelial cell behavior, due to their clinical relevance and scarcity of data on their vascular biosafety. Results Particles with similar chemical composition and distinct size and morphology were tested, i.e. rod-like, nano dimensions and low aspect ratio (HAp1) and needle-shape with wider size and aspect ratio (HAp2). HAp1 and HAp2, at 1 to 10 mg/mL, did not affect haemolysis, platelet adhesion, aggregation and activation, or the coagulation system (intrinsic and extrinsic pathways), although HAp2 exhibited a slight thrombogenic potential at 10 mg/mL. Notwithstanding, significantly lower levels presented dose-dependent toxicity on endothelial cells’ behavior. HAp1 and HAp2 decreased cell viability at levels ≥ 250 and ≥ 50 μg/mL, respectively. At 10 and 50 μg/mL, HAp1 did not interfere with the F-actin cytoskeleton, apoptotic index, cell cycle progression, expression of vWF, VECad and CD31, and the ability to form a network of tubular-like structures. Comparatively, HAp2 caused dose-dependent toxic effects in these parameters in the same concentration range. Conclusion The most relevant observation is the great discrepancy of HA particles’ levels that interfere with the routine blood compatibility assays and the endothelial cell behavior. Further, this difference was also found to be dependent on the particles’ size, morphology and aspect ratio, emphasizing the need of a complementary biological characterization, taking into consideration the endothelial cells’ functionality, to establish the vascular safety of particulate HA.

O presente trabalho aborda os resultados do projeto de extensão “Revelando histórias do Seridó Negro” e sua contribuição para seus participantes e para a formação dos estudantes e docentes envolvidos. O projeto buscou, inicialmente, conhecer histórias das populações negras da região Seridó do Rio Grande do Norte - Brasil, especificamente na comunidade da Boa Vista, município de Parelhas/RN. Através de metodologias da imagem e da voz que retratam a vida cotidiana, buscou dar visibilidade à cultura negra seridoense para materializa-la em uma exposição fotográfica. Constata-se, com a experiência, a importância de atividades dessa natureza, na potencialização de habilidades e no desenvolvimento de novas percepções sobre a realidade local. Nota-se uma interseção entre o ensino da sociologia/antropologia no currículo das estudantes bolsistas e a formação humanística delas, ou seja, uma articulação de saberes que foram socializados via projeto. Percebe-se, por fim, a importância do projeto de extensão como espaço de produção de vínculos com as comunidades e de socialização do conhecimento.

The present study aims to analyze how the Photovoice methodology, derived from visual anthropology, can be used to identify endogenous touristic resources, providing a diagnostic focused on the perspective of local residents in two districts located in north coast of the state of Rio Grande do Norte , Brazil . To do so, the applied experiences were reported by the authors, showing results that point that the Photovoice fulfill the role of identifying tourism potential, as well as can become a tool for enhancement of local culture, through recognition and ownership of the images captured. It was also found that the methodology contributes to the development of a proactive and entrepreneurial attitude in residents of small towns. It is considered as an appropriate methodology to use in an initial stage of the development of community -based tourism.

Background Morphological descriptions comparing Leposternon microcephalum and L. scutigerum have been made previously. However, these taxa lack a formal quantitative morphological characterization, and comparative studies suggest that morphology and burrowing performance are be related. The excavatory movements of L. microcephalum have been described in detail. However, there is a lack of studies comparing locomotor patterns and/or performance among different amphisbaenids sharing the same skull shape. This paper presents the first study of comparative morphometric variations between two closely related amphisbaenid species, L. microcephalum and L. scutigerum, with functional inferences on fossorial locomotion efficiency. Methods Inter-specific morphometric variations were verified through statistical analyses of body and cranial measures of L. microcephalum and L. scutigerum specimens. Their burrowing activity was assessed through X-ray videofluoroscopy and then compared. The influence of morphological variation on the speed of digging was tested among Leposternon individuals. Results Leposternon microcephalum and L. scutigerum are morphometrically distinct species. The first is shorter and robust with a wider head while the other is more elongated and slim with a narrower head. They share the same excavatory movements. The animals analyzed reached relatively high speeds, but individuals with narrower skulls dug faster. A negative correlation between the speed and the width of skull was determined, but not with total length or diameter of the body. Discussion The morphometric differences between L. microcephalum and L. scutigerum are in accord with morphological variations previously described. Since these species performed the same excavation pattern, we may infer that closely related amphisbaenids with the same skull type would exhibit the same excavatory pattern. The negative correlation between head width and excavation speed is also observed in others fossorial squamates. The robustness of the skull is also related to compression force in L. microcephalum. Individuals with wider heads are stronger. Thus, we suggest trade-offs between excavation speed and compression force during burrowing in this species.

This paper presents protests from academically successful students who privately conveyed to the researchers their feelings of personal discontent with schools. The criterion to select this “sample” was that these students, dissatisfied with school but having good marks, would reveal what others, academically less successful, could not express, by not knowing the syllabus as well as those students. However, their complaints are followed by suggestions of changes to be analyzed in this study. Our questions focused especially on the tenth grade, as this grade starts the three-year-cycle preceding university. We attempt to contribute to the issue of teacher education, by focusing on the stream of participative research in educational institutions, conducted by external researchers in cooperation with the institution’s stakeholders, students, and teachers in this study. The data analyzed for this paper came from in-depth interviews conducted, in a non-directive way, with students and their teachers. From the proposals of the students and the comments from teachers, we conclude it is crucial to substantially reduce the predominant teacher-centered methodology of verbal presentation by engaging in students’ activities, including the model of problem-based learning or alike in opposition, in order to rote memorization activities.
