Three-Dimensional Excitation and Emission Fluorescence-Based Method for Evaluation of Maillard Reaction Products in Food Waste Treatment
Authors: Liu Jiaze , Yin Jun , He Xiaozheng , Chen Ting , Shen Dongsheng
Published: November 2018

Hydrothermal treatment (HT) of food waste (FW) can form Maillard reaction products (MRPs), the biorefractory organic matter due to the occurrence of Maillard reaction. However, the integrating qualitative and quantitative approach to assess MRPs is scarce. The goal of this study was to develop a method to characterize and quantify MRPs created by HT of FW. MRPs were identified by molecular weight fractionation, indirect spectrometric indicators, and three-dimensional excitation-emission fluorescence (3DEEM) analysis. The 3DEEM method combined with fluorescence regional integration (FRI) and parallel factor (PARAFAC) analyses was able to differentiate clearly between MRPs and other dissolved organic compounds compared to other approaches. The volume of fluorescence Φ from FRI and maximum fluorescence intensityFmaxfrom PARAFAC were found to be suitable quantitative parameters for determination of MRPs in the hydrothermal FW system. These two parameters were validated with samples from hydrothermal FW under various operating temperatures and pH.

Introduction. Cementoblastoma is a rare and benign odontogenic mesenchymal tumor, often characterized by the formation of cementum-like tissue produced by neoplastic cementoblasts attached to or around the roots of a tooth.Case Report. 22-year-old male patient was referred to the Federal University of Paraná after occasional finding on a routine panoramic radiograph. Clinical examination suggested no alterations. Medical and family history presented no alterations as well. Computed tomographic (CT) showed the presence of a radiopaque area associated with the roots of the impacted third molar measuring 15 mm × 10 mm inside the left maxillary sinus. The treatment plan suggested was to surgically remove it under general anesthesia. An intraoral approach was conducted, using the Newmann incision from the superior left first molar to the retromolar area with anterior and posterior relaxant incisions. Using a Caldwell-Luc access next to the maxillary tuberosity region, the maxillary sinus was exposed and the calcified mass attached to the roots of the tooth was reached. Pathological mass removed was sent for histopathological investigation. Examination revealed dense, mineralized, cementum-like material and vascular soft tissue areas that consisted of cementoblasts. One-year follow-up shows no recurrence and absence of symptoms.

Sasang typology is a traditional Korean medical classification scheme that combines medical management with general medicine and can be applied to chronic diseases. We aimed to analyze differences in Sasang Personality Questionnaire (SPQ) and Sasang Digestive Function Inventory (SDFI) results in patients with diabetes mellitus (DM), hypertension, functional dyspepsia, major depressive disorder (MDD), and adenomyosis. In this cross‐sectional study, data were collected at a medical college hospital in South Korea. A total of 248 patients were included: 52 with DM, 47 with hypertension, 36 with functional dyspepsia, 26 with MDD, and 87 with adenomyosis. The subjects took both the SPQ and the SDFI. The outcome measures in this study were body mass index (BMI), SPQ score, and SDFI score. The DM and hypertension groups, which were expected to demonstrate many Taeeum‐type traits, exhibited high BMI, high SPQ‐Behavior and SDFI‐Appetite scores, and low SPQ‐Emotionality and SDFI‐Digestion scores. The functional dyspepsia group showed low BMI and high scores for SPQ‐Behavior, SPQ‐Emotionality, SDFI‐Digestion, and SDFI‐Appetite. The MDD group demonstrated high SPQ‐Emotionality and SDFI‐Digestion scores, low BMI, and low SPQ‐Behavior and SDFI‐Appetite scores. The adenomyosis group demonstrated high scores for SPQ‐Behavior, SDFI‐Digestion, and SDFI‐Appetite, low BMI, and low SPQ‐Emotionality scores. Different characteristics distinguishing Sasang traits according to chronic diseases were ascertained, especially for Taeeum and Soeum types.

Published: November 2018

To develop natural product resources from the Clausena genus (Rutaceae), the essential oils (EOs) from four Clausena plants (Clausena excavata, C. lansium, C. emarginata, and C. dunniana) were analyzed by GC-MS. Their lethal (contact toxicity) and sublethal effects (repellency) against Liposcelis bostrychophila (LB) adults were also evaluated. Santalene sesquiterpene was the precursor substance of santalol, a valuable perfumery. It was found that plenty of α-santalol (31.7%) and α-santalane (19.5%) contained in C. lansium from Guangxi Province and α-santalene (1.5%) existed in C. emarginata. Contact toxicity of the four EOs was observed, especially C. dunniana (LD50 = 37.26 µg/cm2). Santalol (LD50 = 30.26 µg/cm2) and estragole (LD50 = 30.22 µg/cm2) were the two most toxic compounds. In repellency assays, C. excavate, C. lansium, and C. emarginata exhibited repellent effect at the dose of 63.17 nL/cm2 2 h after exposure (percentage repellencies were 100%, 98%, and 96%, respectively). Four Clausena EOs and santalol had an excellent potential for application in the management of LB. Clausena plants could be further developed to find more resources of natural products.

Published: November 2018

In this paper, we design a chaotic circuit with memristors, which consists of two flux‐controlled memristors and a charge‐controlled memristor, and the dimensionless mathematical model of the circuit was established. Using the conventional dynamic analysis methods, the equilibrium point set and stability of the chaotic system were analyzed, and the distribution of stable and unstable regions corresponding to the memristor initial states was determined. Then, we analyze the dynamical behaviors with the initial states of the memristors and the circuit parameter of the circuit system, respectively. By using spectral entropy (SE) and C0 complexity algorithms, the dynamic characteristics of the system were analyzed. In particular, the 2D and 3D complexity characteristics with multiple varying parameters were analyzed. Some peculiar physical phenomenon such as coexisting attractors was observed. Theoretical analysis and simulation results show that the chaotic circuit has rich dynamical behaviors. The complicated physical phenomenon in the new chaotic circuit enriches the related content of chaotic circuit with memristors.

Published: November 2018

The accurate landscape of transcript isoforms plays an important role in the understanding of gene function and gene regulation. However, building complete transcripts is very challenging for short reads generated using next-generation sequencing. Fortunately, isoform sequencing (Iso-Seq) using single-molecule sequencing technologies, such as PacBio SMRT, provides long reads spanning entire transcript isoforms which do not require assembly. Therefore, we have developed ISOdb, a comprehensive resource database for hosting and carrying out an in-depth analysis of Iso-Seq datasets and visualising the full-length transcript isoforms. The current version of ISOdb has collected 93 publicly available Iso-Seq samples from eight species and presents the samples in two levels: (1) sample level, including metainformation, long read distribution, isoform numbers, and alternative splicing (AS) events of each sample; (2) gene level, including the total isoforms, novel isoform number, novel AS number, and isoform visualisation of each gene. In addition, ISOdb provides a user interface in the website for uploading sample information to facilitate the collection and analysis of researchers’ datasets. Currently, ISOdb is the first repository that offers comprehensive resources and convenient public access for hosting, analysing, and visualising Iso-Seq data, which is freely available.

Published: November 2018

There is a huge amount of data in the opportunity of “turning waste into treasure” with the arrival of the big data age. Urban layout is very important for the development of urban transportation and building system. Once the layout of the city is finalized, it will be difficult to start again. Therefore, the urban architectural layout planning and design have a very important impact. This paper uses the urban architecture layout big data for building layout optimization using advanced computation techniques. Firstly, a big data collection and storage system based on the Hadoop platform is established. Then, the evaluation model of urban building planning based on improved logit and PSO algorithm is established. The PSO algorithm is used to find the suitable area for this kind of building layout, and then through five impact indicators: land prices, rail transit, historical protection, road traffic capacity, and commercial potential have been established by using the following logit linear regression model. Then, the bridge between logit and PSO algorithm is established by the fitness value of particle. The particle in the particle swarm is assigned to the index parameter of logit model, and then the logit model in the evaluation system is run. The performance index corresponding to the set of parameters is obtained. The performance index is passed to the PSO as the fitness value of the particle to search for the best adaptive position. The reasonable degree of regional architectural planning is obtained, and the rationality of urban architectural planning layout is determined.

Published: November 2018

Micro- and nanostructured Ni/NiO surfaces were generated by femtosecond laser structuring for oxygen evolution reaction in alkaline water electrolysis cells. For two different angles between the laser beam and the nickel surface, two different types of laser-structured electrodes were prepared, characterized, and compared with a plane tempered nickel electrode. Their electrochemical activities for the oxygen evolution reaction were tested by using cyclic and linear sweep voltammetry. The chemical surface composition was investigated by X-ray photoelectron spectroscopy. Laser structuring increased the overall electrochemical performance by more than one order of magnitude. The overpotential of the laser-structured electrodes for the oxygen evolution reaction was decreased by more than 100 mV due to high defect densities of the structures created by the laser ablation process.

Authors: McClees Sarah F. , Duncan James Robert , Ceilley Roger , Milless Tiffani L. , Elewski Boni E.
Published: November 2018

Metastasis of any malignancy to the nail unit is uncommon, and only a handful of cases of subungual renal cell carcinoma (RCC) metastasis have been reported. We describe a case of isolated nail dystrophy that proved to be the presenting symptom of a previously undetected RCC. In a patient presenting with a subungual lesion, tumor metastasis to the nail unit should be included in the clinical differential diagnosis in both oncology patients and previously cancer-free individuals, as a subungual metastasis may be the first indication of a clinically silent visceral malignancy.

Published: November 2018

Background/Aims: This study aims to examine the effect of long noncoding RNA HOST2 (LncRNA HOST2) on epithelial-mesenchymal transition (EMT), proliferation, invasion and migration of hepatocellular carcinoma (HCC) cells via activation of the JAK2-STAT3 signaling pathway. Methods: HCC and para-cancerous tissues were collected from 136 HCC patients. Immunohistochemistry was used to detect the expression of JAK2 and STAT3. HCC SMMC7721 cells were grouped into blank, negative control (NC), HOST2 mimic and HOST2 inhibitor groups. The mRNA and protein expression levels of HOST2, JAK2, STAT3, E-cadherin, vimentin, Snail, Slug, Twist and Zeb1 in tissues and cells were determined by reverse transcription -quantitative polymerase chain reaction (RT-qPCR) and Western blotting, respectively. An MTT assay, scratch test and Transwell assay were applied to measure cell proliferation, migration and invasion, respectively. Results: The levels of JAK2, STAT3 and vimentin were higher in HCC tissues, while the expression of E-cadherin was lower in HCC tissues compared with para-cancerous tissues. The silencing of HOST2 significantly decreased cell proliferation, migration and invasion, reduced the levels of HOST2, JAK2, STAT3 and vimentin, and elevated the expression of E-cadherin. HOST2 silencing also decreased the levels of Snail, Slug and Twist but increased the level of Zeb1 protein, while the opposite findings were observed in the HOST2 mimic group. Conclusion: These results reveal a possible mechanism in HCC in which LncRNA HOST2 may increase EMT and enhance proliferation, invasion and metastasis of HCC cells via activation of the JAK2-STAT3 signaling pathway.

Published: November 2018

Background/Aims: Gap junctions, which are assembled by connexins, can directly connect the cytoplasm of adjacent cells and enable gap junctional intercellular communication (GJIC) as well as metabolic coupling between neighboring cells. Here, we investigated the role of connexin 43 (Cx43) and its derived GJIC in the interplay between non-small cell lung cancer (NSCLC) cells and cancer-associated fibroblasts (CAFs). Methods: CAFs and NSCLC cells were co-cultured with direct contact and separated using flow cytometry. Glucose uptake, lactate production, and the expression and activity of PKM-2 and LDH-A in sorted CAFs were measured by a colorimetric assay, western blotting, and enzyme-linked immunosorbent assay (ELISA). Meanwhile, E-cadherin and N-cadherin expression and the migration and invasion of sorted NSCLC cells were detected by western blotting, wound width, and Transwell assays. Pyruvate, acetyl-CoA, and citric acid levels, ATP levels, and LDH-B and α-KG activity in sorted NSCLC cells were determined by a colorimetric or fluorometric assay and ELISA, respectively. Functional GJIC between cells and the subcellular location of connexins were detected by a “Parachute” assay and immunofluorescence. Levels of α-SMA, Cx43, and LDH-B in tissue from patients with NSCLC were determined by immunohistochemistry. Results: Cx43 accumulated in the plasma membrane, which favored the assembly of asymmetric unidirectional GJIC from CAFs to NSCLC cells. CAFs underwent increased aerobic glycolysis and promoted the epithelial-mesenchymal transition, migration, and invasion of NSCLC cells. In contrast, NSCLC cells experienced enhanced oxidative phosphorylation upon CAF stimulation, with an increase in ATP generation and thereby activation of the PI3K/Akt and MAPK/ERK pathways. Metabolic coupling between CAFs and NSCLC cells was under the strict control of Cx43-formed unidirectional GJIC. Patients with high tri-expression of α-SMA, Cx43, and LDH-B had the shortest overall survival and relapse-free survival compared with those with individual overexpression or high bi-expression. Conclusion: Cx43-formed unidirectional GJIC plays a critical role in mediating close metabolic cooperation between CAFs and NSCLC cells to support the malignant progression of NSCLC.
Cytoskeleton Structure in Mouse Sperm and Testes After 30 Days of Hindlimb Unloading and 12 Hours of Recovery
Authors: Usik Maria A. , Ogneva Irina V.
Published: November 2018

Background/Aims: Changes in the external mechanical field result in cytoskeleton reorganization and the formation of adaptive patterns in different types of cells, including somatic cells and sex cells. The aim of this research was to study the protein and mRNA content of cytoskeletal and sperm-specific genes in the sperm and testis cells of mice. Methods: Mice were subjected to 30 days of antiorthostatic suspension to simulate weightlessness, followed by 12 h of recovery, while receiving essential phospholipids at a dosage of 500 mg/kg/day (30HSE and 30HSE+12h groups) or a similar dosage of a placebo (30HS and 30HS+12h groups). Accordingly, reference groups (CE group and C group) were formed. The total number and the percentage of motile spermatozoa were calculated using a Makler chamber. To analyze the number of viable spermatozoa and the permeability of their membranes, eosin staining was used as well as Diff-Quick for a morphological evaluation. Relative protein and mRNA content was estimated in a western blot and quantitative PCR assay, respectively. Results: The relative protein expression levels of actin (beta and gamma) and two alpha-actinin isoforms (1 and 4) remained constant in the sperm of all study groups, except for the 30HS+12h group, where the alpha-actinin-4 level was 13% higher than in the reference group (p < 0.1). In the testis cells, the relative actin isoform content was equivalent to that in the spermatozoa. However, in the testis cells, the ACTN1 mRNA content was 17% higher in the 30HS group than in the C group (p < 0.05), and decreased after 12 h of recovery. In contrast, the ACTN4 mRNA content was 20% lower in the 30HS group than in the reference group (p < 0.05) and increased after the 12-h recovery period. At the same time, in the group administered the essential phospholipids, the relative ACTN1 and ACTN4 mRNA content did not differ from those of the reference group. The relative beta-tubulin content was similar in the reference C group and the reference CE group, which was administered the essential phospholipids. In the 30HS and 30HS+12h groups, the beta-tubulin content decreased by 19% and 22% (p < 0.05), respectively, and they also decreased in the groups administered the essential phospholipids (30HSE and 30HSE+12h groups, by 27% and 33%, respectively, p < 0.05). In the testis tissue, the relative tubulin content did not change in any of the experimental groups. At the same time, the relative mRNA content of the genes encoding the studied cytoskeletal proteins increased, which may indicate the protein content was regulated mainly at the translational level. Conclusion: The spermogram parameters and the content of the sperm-specific proteins and the associated mRNAs revealed a decrease in the number of mature spermatozoa in mice suspended under conditions of weightlessness. Moreover, the decrease was prevented by the administration of essential phospholipids.
The TRPC6-AMPK Pathway is Involved in Insulin-Dependent Cytoskeleton Reorganization and Glucose Uptake in Cultured Rat Podocytes

Published: November 2018

Background/Aims: Podocytes are dynamic polarized cells on the surface of glomerular capillaries that are an essential part of the glomerular filtration barrier. AMP-activated protein kinase (AMPK), a key regulator of glucose and fatty acid metabolism, plays a major role in obesity and type 2 diabetes. Accumulating evidence suggests that TRPC6 channels are crucial mediators of calcium transport in podocytes and are involved in regulating glomerular filtration. Here we investigated whether the AMPK-TRPC6 pathway is involved in insulin-dependent cytoskeleton reorganization and glucose uptake in cultured rat podocytes. Methods: Western blot and immunofluorescence analysis confirmed AMPKα and TRPC6 expression, the phosphorylation of proteins associated with actin cytoskeleton reorganization (PAK, rac1, and cofilin), and the expression of insulin signaling proteins (Akt, Insulin receptor). Coimmunoprecipitation and immunofluorescence results demonstrated AMPKα/TRPC6 interaction. To ask whether TRPC6 is involved in the insulin regulation of glucose transport, we measured insulin-dependent (1, 2-3H)-deoxy-D-glucose uptake into podocytes after reducing TRPC6 activity pharmacologically and biochemically (TRPC6 siRNA). Results: The results suggested a key role for the TRPC6 channel in the mediation of insulin-dependent activation of AMPKα2 and glucose uptake. Moreover, AMPK and TRPC6 activation were required to stimulate the Rac1 signaling pathway. Conclusion: These results suggest a potentially important new mechanism that regulates glucose transport in podocytes and that could be injurious during diabetes.
Association of Dopamine Beta-Hydroxylase Polymorphisms with Alzheimer’s Disease, Parkinson’s Disease and Schizophrenia: Evidence Based on Currently Available Loci
Authors: Tang Siqi , Yao Bin , Li Na , Lin Shuhuang , Huang Zunnan 
Published: November 2018

Background/Aims: The neuropathies Alzheimer’s disease (AD), Parkinson’s disease (PD), and schizophrenia (SCZ) have different pathological mechanisms but share some common neurodegenerative features, such as gradual loss of neuronal structure and function. Dopamine beta-hydroxylase (DBH), a gene located in the chromosomal region 9q34, plays a crucial role in the process of converting dopamine into norepinephrine (NE). Several case–control studies have reported this pathway in the pathogenesis of AD, PD and SCZ. However, the results are controversial. Methods: We conducted a meta-analysis to estimate the associations between polymorphisms in this gene and AD, PD and SCZ. Seven databases (PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wan Fang, SZ Gene and AD Gene) were searched to identify eligible studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the associations of DBH variants with AD, PD and SCZ susceptibility. Results: A total of 41 studies involving 10506 cases and 15083 controls were included in our meta-analysis. The analysis results indicated that a lack of association (P > 0.05) was observed between most of the currently available DBH polymorphisms and the neurological diseases AD, PD and SCZ; however, the DBH rs1611131 (allelic model: OR = 0.889, 95% CI: 0.815 - 0.969; dominant model: OR = 0.868, 95% CI: 0.778 - 0.968), rs2283123 (allelic model: OR = 0.285, 95% CI: 0.095 - 0.862; dominant model: OR = 0.290, 95% CI: 0.094 -0.897) and rs2007153 (allelic model: OR = 2.196, 95% CI: 1.506 - 3.200; dominant model: OR = 2.985, 95% CI: 1.465 - 6.084; recessive model: OR = 2.729, 95% CI: 1.548 - 4.812) variants were shown to be significantly associated with the risk of AD (the former variant) and SCZ (the latter two variants). Conclusion: On the one hand, most DBH polymorphisms from the currently available loci showed no linkage to AD, PD or SCZ, indicating the lower possibility of these loci serving as genetic markers of the risks of diseases with neurodegenerative characteristics. On the other hand, the DBH rs2283123 and rs2007153 polymorphisms could have opposite effects on SCZ development in Caucasians and be more specific in Croatians, while the DBH rs1611131 minor variant might have a protective effect on AD risk in Caucasians; however, these results require further study.
Modesty, Objectification, and Disordered Eating Patterns: A Comparative Study between Veiled and Unveiled Muslim Women Residing in Kuwait
Authors: Al-Mutawa Naif , Schuilenberg Susannah-Joy , Justine Rumia , Kulsoom Taher Sarah
Published: November 2018

Background: The common thread running through all forms of sexual objectification is the experience of being treated as a body (or collection of body parts) valued predominantly for its use to (or consumption by) others. If girls and women adopt a peculiar view of the self, an effect called self-objectification, this may contribute to depression, sexual dysfunction, and eating disorders. The objective of this study is to investigate the impact of modesty (in terms of veiling, i.e., hijab) on objectification, by others and by the self, body image, and behaviors indicative of eating disturbance in veiled and unveiled Muslim women in Kuwait. Methods: This is a community-based, cross-sectional study conducted through an online survey. The respondents were females living in Kuwait. Results: Unveiled women experienced more objectification by others than veiled women. There were no significant differences found between veiled and unveiled women in self-objectification and eating disorder symptomatology. There is a significant negative relationship between modesty of clothing and objectification by others. No significant relationship was found between modesty of clothing and the self-objectification and eating disorder scales. For the objectification by others scale, data show that there is a positive relationship between this scale and eating disorders. Eating disorders were found to have a negative relationship with self-objectification. Conclusion: The results of the study are significant as they clearly demonstrate a weak negative relationship between clothing preferences/affiliations and eating disorders.

As paixões na canção popular: percursos semióticos
Authors: Caretta Álvaro Antônio
Published: November 2018

Neste artigo, pretendemos, a princípio, apresentar um roteiro do percurso teórico da semiótica das paixões e, a seguir, demonstrar a aplicação de suas propostas na análise de canções. Para isso, partindo dos princípios da “semiótica da ação”, fundada sobre o esquema narrativo e o fazer do sujeito, descreveremos o percurso teórico realizado em busca da compreensão dos estados passionais do sujeito, o que levou os semioticistas a se dedicarem aos estudos das modalidades do ser e às estruturas profundas do percurso gerativo, conjunto teórico esse intitulado semiótica das paixões. Com base nessas propostas para o estudo dos estados passionais do sujeito, tomaremos como objeto de análise canções representativas do samba-canção, gênero musical que valorizou ao extremo a representação dos estados passionais em suas letras e explorou intensamente a passionalização em suas melodias. Tendo em vista a importância da teoria semiótica francesa para os estudos discursivos, o conhecimento de seus princípios, de sua evolução e de suas contribuições é fundamental para que se possa compreender as suas possibilidades e potencialidades, com destaque para as pesquisas sobre as linguagens sincréticas, particularmente a canção.
A expressão do ornamento contemporâneo na construção do imaginário urbano na avenida Faria Lima
Authors: Souza Luciana Coutinho Pagliarini
Published: November 2018

Este artigo tem como propósito apresentar o ornamento arquitetônico na contemporaneidade como linguagem produtora de sentidos e traz como corpus os edifícios da Av. Faria Lima – São Paulo. Interessa-nos refletir sobre o diálogo que a arquitetura contemporânea estabelece com a cultura, participando da construção de uma imagem e de um imaginário dentro de determinado contexto. Para esse fim, a análise cultural da cidade contemporânea fundamenta-se em Jameson (2006) e Montaner (2002, 2009); a relação entre ornamento e arquitetura se dá na esteira de Sá (2005), Moussavi e Kubo (2008), Venturi (2003). Para tratar da relação entre cidade e comunicação, assim como dos conceitos de imagem e imaginário nas cidades, apoiamo-nos em Ferrara (1988, 2000) e Lynch (2011); finalmente, para a metodologia de análise dos ornamentos, valemo-nos da semiótica de Peirce (2003). Este estudo auxilia no entendimento de que a arquitetura cria significados sociais para além de suas funções práticas, sendo uma expressão da sociedade e do meio onde está inserida.
O tempo, o valor e a prostituta: reflexões sobre “Geni e o Zepelim” de Chico Buarque
Authors: Araujo Murillo Clementino de
Published: November 2018

Este artigo propõe uma reflexão sobre a construção do tempo, do valor e da prostituta na canção “Geni e o Zepelim”, de Chico Buarque. A partir da análise do nível discursivo do texto, é possível perceber que há um jogo entre as diferentes vozes dos atores do enunciado, a saber, o narrador, a cidade, o comandante do zepelim e Geni, bem como uma mudança no uso dos sistemas temporais enunciativo e enuncivo. No nível narrativo ocorre uma dupla manipulação do comandante e da cidade em relação à Geni, que é obrigada a se deitar com o oficial para evitar o bombardeio anunciado. Mesmo após ter cumprido a performance que lhe tinha sido designada, a moça recebe uma sanção negativa da cidade. O resultado final da sequência de programas narrativos é a reificação de Geni. Por fim, do ponto de vista de suas estruturas tensivas, o discurso se organiza em termos de continuidade e descontinuidade. Por um lado, a chegada do comandante do zepelim pode ser interpretada como um acontecimento, por outro lado, a prostituição habitual de Geni se caracteriza como um exercício. Em geral, “Geni e o Zepelim” demonstra que o papel temático-figurativo da prostituta se investe de uma configuração axiológica positiva ou negativa em função do tempo e dos interesses sociais em jogo.
Germain Bazin e o Iphan
Authors: Uribarren Maria Sabina
Published: November 2018

Germain Bazin, curador-chefe da Seção de Pinturas do Museu do Louvre (1950-1965), contribuiu para a consolidação da arte barroca como paradigma da produção artística colonial brasileira. Considerado por Rodrigo Melo Franco de Andrade como “o eminente historiador e crítico de arte [...] [que] observou, com fundamento, [...] as manifestações mais barrocas da arquitetura do Brasil”, o historiador francês coadjuvou para chancelar mundialmente aspectos fundamentais dos discursos do Instituto do Patrimônio Histórico e Artístico Nacional (Iphan) sobre o barroco por meio de ações diversificadas, tais como a redação de artigos para jornais e revistas especializadas, a realização de palestras, a promoção de exposições e, sobretudo, a participação em projetos bibliográficos sobre a arte e a arquitetura barroca do Brasil. Este artigo reconstrói suscintamente a trajetória europeia de Bazin e apresenta uma aproximação às relações pessoais e profissionais estabelecidas por ele, que possibilitaram a sua imersão no patrimônio cultural brasileiro. Delinearemos, finalmente, os principais projetos editoriais sobre arte e arquitetura barroca brasileira nos quais participou e que tiveram o Iphan como instituição colaboradora fundamental.

Este artigo é um esforço de compreender a política de patrimônio cultural francesa, pioneira no campo da preservação e valorização dos bens caros à memória nacional, e que tem passado por constantes mudanças e adaptações, principalmente a partir da adoção, nos anos 1960, do inventário geral do patrimônio cultural, com base em uma série de ações que resultaram em uma progressiva sensibilidade patrimonial e na extensão geográfica do fenômeno. Com isso, buscamos perceber tendências e desafios presentes nesse tipo de política, apresentando ao final alguns exemplos de ações recentes.
O corpo materno como provocação entre o público e o privado
Authors: Abreu Mariela Lamberti de
Published: November 2018

O artigo se propõe a pensar na dualidade público-privado sob a ótica da crítica feminista, inclusive questionando essa separação e apresentando diferentes argumentos de algumas autoras. Com isso, pretende-se encontrar pontos de interseção com uma performance artística criada também para provocar e questionar as paredes que separam a casa da rua, que põe a mulher quase como refém da lógica das teorias políticas liberais, hierarquizando a vida pública e a vida privada com critérios bastante segregadores.

Transgêneros teatrais
Authors: Friques Manoel Silvestre
Published: November 2018

O presente ensaio busca analisar na produção teatral contemporânea brasileira estratégias cênicas e discursivas que descortinem, conforme Adrienne Rich, a “via da heterossexualidade compulsória”. Sendo assim, o propósito aqui é observar certas confluências temático-formais entre os respectivos debates a respeito dos estudos de gêneros artísticos e sexuais. O intuito é menos o de classificar do que o de revelar diferenças, a partir de um exercício instável de justaposição, entre as práticas teatrais brasileiras e alguns enquadramentos teóricos encontrados no âmbito dos estudos de gênero e sexualidade. Como pano de fundo residem as seguintes questões: em que medida tais estudos podem revelar um novo olhar sobre as teorias do teatro? O questionamento dos sistemas normativos de gênero e sexualidade equivalem às desconfianças quanto às taxonomias artísticas?

Hobbes e os fundamentos do sistema legal codificado:
Authors: Chiappin José Raymundo Novaes , Leister Ana Carolina Corrêa da Costa
Published: November 2018

O artigo foca na tese de que o sistema legal codificado, a civil law, é tecnologia produzida por Hobbes do direito como ciência do artificial, como a geometria. A civil law deve substituir a common law. A common law é resultado de uma atividade artesanal baseada na prática e na experiência dependente de homens virtuosos. A civil law é construída para ser compatível com a concepção de Hobbes do Estado como representado por um soberano, construído como pessoa, com poder supremo, para produzir leis como comandos. Ela tem base na ontologia do cogito, agente racional e autônomo. Hobbes desenvolve um método para fazer a escolha racional de uma ação pela avaliação das suas consequências ou efeitos. Ele é usado para elaborar a legislação como racional, particularmente, a penal. O Estado e a civil law transformam o cogito em pessoa, sujeito capaz de direitos e obrigações. O cogito e a pessoa natural são modelos para instituição do corpo político como pessoa artificial. As corporações tornam-se responsáveis por suas ações. Há empenho para alinhar o interesse privado com o público e regular os corpos políticos para evitar que o primeiro se aproprie do segundo. A civil law constrói o Estado como máquina de precisão entre “too much authority” e “great liberty”.
A longa vida do Código Civil
Authors: Lopes José Reinaldo de Lima
Published: November 2018

O texto coloca em dúvida a ideia de que o Código Civil esteve vigente por longo tempo no Brasil. Ao contrário, o artigo argumenta que o Código foi sendo alterado e o que permaneceu em vigor foi uma certa ideologia do Direito Civil, fundada sobretudo em mitos de continuidade. Essa ideologia dificultou a renovação do pensamento jurídico brasileiro porque o ensino se dava sobre as bases da ideia unitária do código e não sobre a realidade do direito positivo ou das práticas cotidianas dos cidadãos e dos juristas.

Requerimento ao Conselho da Cidade de Leipzig
Authors: Ricciardi Rubens Russomanno , Hofmann Dorothea , Bach Johann Sebastian
Published: November 2018

Trata-se da tradução, com notas comentadas, feita por Rubens Russomanno Ricciardi e Dorothea Hofmann, de um requerimento manuscrito, redigido por Bach, em 1730, endereçado ao Conselho da Cidade de Leipzig. Não obstante se referir à música sacra, Bach se concentra em condições artísticas para a performance musical de seus conjuntos vocal e instrumental. Reivindica também um número maior de bolsas para seus alunos, bem como critérios mais rigorosos na admissão de estudantes para Escola da Igreja de Tomé. Por fim, Bach, em sua pedagogia, divide os alunos em três categorias: os utilizáveis, os ainda não utilizáveis e os incapazes.
Impacts of Radiation and Upper-Tropospheric Temperatures on Tropical Cyclone Structure and Intensity
Authors: Trabing Benjamin C. , Bell Michael M. , Brown Bonnie R.
Published: November 2018

Potential intensity theory predicts that the upper-tropospheric temperature acts as an important constraint on tropical cyclone (TC) intensity. The physical mechanisms through which the upper troposphere impacts TC intensity and structure have not been fully explored, however, due in part to limited observations and the complex interactions between clouds, radiation, and TC dynamics. In this study, idealized Weather Research and Forecasting Model ensembles initialized with a combination of three different tropopause temperatures and with no radiation, longwave radiation only, and full diurnal radiation are used to examine the physical mechanisms in the TC–upper-tropospheric temperature relationship on weather time scales. Simulated TC intensity and structure are strongly sensitive to colder tropopause temperatures using only longwave radiation, but are less sensitive using full radiation and no radiation. Colder tropopause temperatures result in deeper convection and increased ice mass aloft in all cases, but are more intense only when radiation was included. Deeper convection leads to increased local longwave cooling rates but reduced top-of-the-atmosphere outgoing longwave radiation, such that the total radiative heat sink is reduced from a Carnot engine perspective in stronger storms. We hypothesize that a balanced response in the secondary circulation described by the Eliassen equation arises from upper-troposphere radiative cooling anomalies that lead to stronger tangential winds. The results of this study further suggest that radiation and cloud–radiative feedbacks have important impacts on weather time scales.
Spatiotemporal Changes in Precipitation Extremes over Canada and Their Teleconnections to Large-Scale Climate Patterns
Authors: Yang Yang , Gan Thian Yew , Tan Xuezhi
Published: November 2018

In the past few decades, there have been more extreme climate events occurring worldwide, including Canada, which has also suffered from many extreme precipitation events. In this paper, trend analysis, probability distribution functions, principal component analysis, and wavelet analysis were used to investigate the spatial and temporal patterns of extreme precipitation events of Canada. Ten extreme precipitation indices were calculated using long-term daily precipitation data (1950–2012) from 164 Canadian gauging stations. Several large-scale climate patterns such as El Niño–Southern Oscillation (ENSO), Pacific decadal oscillation (PDO), Pacific–North American (PNA), and North Atlantic Oscillation (NAO) were selected to analyze the relationships between extreme precipitation and climate indices. Convective available potential energy (CAPE), specific humidity, and surface temperature were employed to investigate potential causes of trends in extreme precipitation. The results reveal statistically significant positive trends for most extreme precipitation indices, which means that extreme precipitation of Canada has generally become more severe since the mid-twentieth century. The majority of indices display more increasing trends along the southern border of Canada while decreasing trends dominated the central Canadian Prairies. In addition, strong teleconnections are found between extreme precipitation and climate indices, but the effects of climate patterns differ from region to region. Furthermore, complex interactions of climate patterns with synoptic atmospheric circulations can also affect precipitation variability, and changes to the summer and winter extreme precipitation could be explained more by the thermodynamic impact and the combined thermodynamic and dynamic effects, respectively. The seasonal CAPE, specific humidity, and temperature are correlated to Canadian extreme precipitation, but the correlations are season dependent, which could be positive or negative.
Global Climatologies of Fronts, Airmass Boundaries, and Airstream Boundaries: Why the Definition of “Front” Matters
Authors: Thomas Carl M. , Schultz David M.
Published: November 2018

Climatologies of fronts, airmass boundaries, and airstream boundaries can be calculated using automated approaches on gridded data. Such approaches may require choices to define a front, including a quantity (or quantities) to diagnose the front, a mathematical function(s) that operates upon the quantity to produce a diagnostic field, a level(s) at which the field is calculated, and a minimum threshold(s) in the magnitude of the field. To understand how resulting climatologies depend upon these choices using a consistent dataset, ERA-Interim reanalyses from 1979 to 2016 are used to construct global monthly climatologies for various definitions of fronts and airstream boundaries from potential temperature, equivalent potential temperature, water vapor mixing ratio, and wind, including gradients, thermal front parameter, frontogenesis, and asymptotic contraction rate at the surface and 850 hPa. Maps of automated fronts are similar to manual analyses when about 10% of the map is identified as a front. Definitions of fronts that use potential temperature or frontogenesis produce climatologies similar to those of manually analyzed fronts with maxima along the major storm tracks and their seasonal migrations. In contrast, definitions that use equivalent potential temperature or the thermal front parameter produce fewer fronts at higher latitudes and more fronts at lower latitudes, more akin to airmass boundaries than fronts. Although surface fronts defined by thermodynamic quantities are more infrequent over the oceans than at 850 hPa, they are more frequent when using metrics that include the wind field (e.g., frontogenesis, asymptotic contraction rate).
Central and Peripheral Cues to Difficulty in a Dynamic Task
Authors: Vangsness Lisa , Young Michael
Published: November 2018

Objective:

We used this experiment to determine the degree to which cues to difficulty are used to make judgments of difficulty (JODs).

Background:

Traditional approaches involve seeking to standardize the information people used to evaluate subjective workload; however, it is likely that conscious and unconscious cues underlie peoples’ JODs.

Method:

We designed a video game task that tested the degree to which time-on-task, performance-based feedback, and central cues to difficulty informed JODs. These relationships were modeled along five continuous dimensions of difficulty.

Results:

Central cues most strongly contributed to JODs; judgments were supplemented by peripheral cues (performance-based feedback and time-on-task) even though these cues were not always valid. In addition, participants became more likely to rate the task as “easier” over time.

Conclusion:

Although central cues are strong predictors of task difficulty, people confuse task difficulty (central cues), effort allocation and skill (performance-based feedback), and proxy cues to difficulty (time) when making JODs.

Application:

Identifying the functional relationships between cues to difficulty and JODs will provide valuable insight regarding the information that people use to evaluate tasks and to make decisions.
Ambidexterity as Historically Embedded Process: Evidence From NASA, 1958 to 2016
Authors: Heracleous Loizos , Yniguez Carlos , Gonzalez Steven A.
Published: November 2018

Even though the growing ambidexterity literature has delivered useful insights, this theme has been researched largely in static and a-contextual terms, without adequate attention to how an organization’s history and context can shape its present. In this article, we employ NASA (National Aeronautics and Space Administration) as an in-depth case study to trace how its historical trajectory has shaped its current propensity to be ambidextrous. Our study reveals organizational ambidexterity as a path-dependent, contingent process rather than something necessarily achievable via the more generic prescriptions of structural, temporal, or contextual ambidexterity models.
