Authors: Moeenuddin Zohra , Kim-Kupfer Caroline , Owchar Erica , Baker Joshua , Duffield Amy , Santoro Thomas
Published: May 2019

This study evaluates the influence of comprehensive health care coordination for children with special health care needs (CSHCN) in a resident continuity clinic. CSHCN patients were identified from 2 resident continuity panels. Patients were eligible with a score of 2 or greater on the CSHCN screener. Interventions included extended appointment times, a binder, and direct phone access to the social worker who facilitated follow-up appointment scheduling. Data measured included completed and no-show visits for primary care and subspecialty appointments, hospitalization and emergency department visits, use of binders, and parent satisfaction surveys. Patients with a baseline CSHCN screener score ≥4 were 15.6 times more likely to keep their appointment after enrollment ( P = .0035). Mental health no-show visits decreased significantly ( P < .0001). The utilization of components of comprehensive team-based care coordination, even with limited resources, can improve the delivery of health care for children with complex medical needs and mental health disorders in a resident-based clinic.
Traumatic Brain Injury in Adolescence and the Family Resilience Process: A Case Study
Authors: Gauvin-Lepage Jérôme
Published: May 2019

Introduction

The aim of this study was to better understand the family resilience process following a severe traumatic brain injury during adolescence.

Case Presentation

Inspired by the humanistic model of nursing care as a disciplinary perspective, this study used a qualitative and inductive case study design.

Management and Outcome

The data analysis yielded six themes as well as four subthemes that illustrate this family’s resilience process. The most important factors that emerged are (a) family characteristics (i.e., a fighter personality, cultural and spiritual beliefs, presence of hope, keeping a sense of humor), (b) support of family members, (c) support of friends, (d) practicing sports and leisure activities, (e) back-to-school support, and (f) feeling helpful to the adolescent.

Discussion

This study provides interesting avenues with regard to the implementation of strategies to foster the resilience process in families during particularly difficult situations in their lives, such as a traumatic brain injury during adolescence.
Willingness to Pay for Mandibular Overdentures: A Societal Perspective
Authors: Srivastava A. , Esfandiari S. , Madathil S.A. , Birch S. , Feine J.S.
Published: May 2019

Objectives:

Dental services in many countries are funded out-of-pocket by patients whose acceptance of a dental treatment depends on their valuation of it. Using a willingness-to-pay (WTP) strategy, this study aimed to determine how people who do not wear dentures value the benefits of dentures retained by implants and what factors explain variations in WTP among subjects.

Methods:

Telephone numbers of a representative Canadian sample were obtained from a consumer database provider. Respondents completed either an internet-based or telephone survey with 3 payment scenarios: paying oneself (out-of-pocket), coverage with private health insurance, and publicly financed through additional taxes. Personal information data (e.g., age, income) were used as independent variables in regression models to assess the determinants of WTP amounts.

Results:

Among 1,096 respondents, 317 participated in the survey (response rate, 28.9%). The mean WTP of participants (mean ± SD age: 41.2 ± 0.6 y; 54.3% male) who were dentate/partially edentate was $5,347 for implant overdentures. Considering a 1 in 5 chance of becoming edentate, they were willing to pay $26.93 as monthly payments for private insurance. They were also willing to pay an additional yearly tax of $103.63 to support a public program. WTP private payments increased substantially with increase in household income and dental needs.

Conclusion:

This preference study provides information to dentists, insurance companies, and policy makers on what dentate people are willing to pay for implant overdentures, whether directly or with insurance/government coverage.

Knowledge Transfer Statement:

This study provides results of interest to many stakeholders. For clinicians, the results reveal what people are willing to pay for implant overdentures for themselves. It also provides information to employers and insurance companies on how people value having coverage for this kind of service. Furthermore, it provides public policy makers the value that people place on public funding of such treatments and how they would support a decision to publicly fund such a treatment.
Shape grammar, culture, and generation of vernacular houses (a practice on the villages adjacent to rice fields of Mazandaran, in the north of Iran)
Authors: Yousefniapasha Majid , Teeling Catherine , Rollo John , Bunt Dick
Published: May 2019

This article is about an investigation exploring the vernacular environment of the villages adjacent to the rice fields of Mazandaran in order to identify the configuration and characteristic of its vernacular dwellings, and applied grammatical rules. In this regard, based on case study research, 4 villages and 44 houses within them have been investigated employing different methods including measurement, mapping, visual recording, one on one, and focus group interviews. Houses have been analysed based on the framework that shape grammars provided towards identification of compositional rules. Criteria and influential factors for creation of rules have been achieved through cultural and climatic studies that justify their appropriateness. This process has been successfully examined through plan creation of four different types of vernacular houses. The result shows that the set of rules contributed by this research can be efficient for generation of vernacular houses within the region of this study.
Evaluating Effect Size in Psychological Research: Sense and Nonsense
Authors: Funder David C. , Ozer Daniel J.
Published: May 2019

Effect sizes are underappreciated and often misinterpreted—the most common mistakes being to describe them in ways that are uninformative (e.g., using arbitrary standards) or misleading (e.g., squaring effect-size rs). We propose that effect sizes can be usefully evaluated by comparing them with well-understood benchmarks or by considering them in terms of concrete consequences. In that light, we conclude that when reliably estimated (a critical consideration), an effect-size r of .05 indicates an effect that is very small for the explanation of single events but potentially consequential in the not-very-long run, an effect-size r of .10 indicates an effect that is still small at the level of single events but potentially more ultimately consequential, an effect-size r of .20 indicates a medium effect that is of some explanatory and practical use even in the short run and therefore even more important, and an effect-size r of .30 indicates a large effect that is potentially powerful in both the short and the long run. A very large effect size ( r = .40 or greater) in the context of psychological research is likely to be a gross overestimate that will rarely be found in a large sample or in a replication. Our goal is to help advance the treatment of effect sizes so that rather than being numbers that are ignored, reported without interpretation, or interpreted superficially or incorrectly, they become aspects of research reports that can better inform the application and theoretical development of psychological research.

Published: May 2019

Patients with classic hydroa vacciniforme–like lymphoproliferative disorder (HVLPD) typically have high levels of Epstein-Barr virus (EBV) DNA in T cells and/or natural killer (NK) cells in blood and skin lesions induced by sun exposure that are infiltrated with EBV-infected lymphocytes. HVLPD is very rare in the United States and Europe but more common in Asia and South America. The disease can progress to a systemic form that may result in fatal lymphoma. We report our 11-year experience with 16 HVLPD patients from the United States and England and found that whites were less likely to develop systemic EBV disease (1/10) than nonwhites (5/6). All (10/10) of the white patients were generally in good health at last follow-up, while two-thirds (4/6) of the nonwhite patients required hematopoietic stem cell transplantation. Nonwhite patients had later age of onset of HVLPD than white patients (median age, 8 vs 5 years) and higher levels of EBV DNA (median, 1 515 000 vs 250 000 copies/ml) and more often had low numbers of NK cells (83% vs 50% of patients) and T-cell clones in the blood (83% vs 30% of patients). RNA-sequencing analysis of an HVLPD skin lesion in a white patient compared with his normal skin showed increased expression of interferon-γ and chemokines that attract T cells and NK cells. Thus, white patients with HVLPD were less likely to have systemic disease with EBV and had a much better prognosis than nonwhite patients. This trial was registered at www.clinicaltrials.gov as #NCT00369421 and #NCT00032513.
RETRACTED ARTICLE: The distribution and socioeconomic burden of Hepatitis C virus in South Australia: a cross-sectional study 2010–2016
Authors: Edmunds Bernard Luke , Miller Emma Ruth , Tsourtos George
Published: May 2019

Background

Hepatitis C virus infection (HCV) is a communicable disease of increasing global importance with 1.75 million new infections and 400,000 related deaths annually. Until recently, treatment options have had low uptake and most infected people remain untreated. New Direct Acting Antiviral medications can clear the virus in around 95% of cases, with few side-effects. These medications are restricted in most countries but freely accessible in Australia, yet most people still remain untreated. This study applies a cross-sectional research design to investigate the socio-spatial distribution of HCV in South Australia, to identify vulnerable populations, and examine epidemiological factors to potentially inform future targeted strategies for improved treatment uptake.

Method

HCV surveillance data were sourced from South Australia’s Communicable Diseases Control Branch and socio-economic population data from the Australian Bureau of Statistics from January 2010 to December 2016 inclusive. HCV cases were spatially mapped at postcode level. Multivariate logistic regression identified independent predictors of demographic risks for HCV notification and notification source.

Results

HCV notifications (n = 3356) were seven times more likely to be from people residing in the poorest areas with high rates of non-employment (75%; n = 1876) and injecting drug use (74%; n = 1862) reported. Notifications among Aboriginal and Torres Strait Islander people were around six times that of non-Indigenous people. HCV notifications negatively correlated (Spearman’s rho − 0.426; p < 0.001) with socio-economic status (residential postcode socio-economic resources Index). History of imprisonment independently predicted HCV diagnoses in lesser economically-resourced areas (RR1.5; p < 0.001). Independent predictors of diagnosis elsewhere than in general practices were non-employment (RR 4.6; p = 0.028), being male (RR 2.5; p < 0.001), and younger than mean age at diagnosis (RR 2.1; p = 0.006).

Conclusions

Most people diagnosed with HCV were from marginalised sub-populations. Given general practitioners are pivotal to providing effective HCV treatment for many people in Australia a most concerning finding was that non-employed people were statistically less likely to be diagnosed by general practitioners. These findings highlight a need for further action aimed at improving healthcare access and treatment uptake to help reduce the burden of HCV for marginalised people, and progress the vision of eliminating HCV as a major public health threat.
Is surgical axillary staging necessary in women with T1 breast cancer who are treated with breast‐conserving therapy?
Authors: Wang Jin , Tang Hailin , Li Xing , Song Cailu , Xiong Zhenchong , Wang Xi , Xie Xiaoming , Tang Jun
Published: May 2019

Background

In the post‐Z0011 trial era, the need to perform surgical axillary staging for early‐stage breast cancer patients, who are treated with breast‐conserving therapy (BCT), is being questioned. We conducted a retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER) database to evaluate the safety of waiving surgical axillary staging in patients with T1 breast cancer treated with BCT.

Methods

A total of 166,615 eligible patients diagnosed between 2000 and 2012 were divided into staging (sentinel lymph node biopsy or axillary lymph node dissection) and non‐staging (no lymph node examined or only needle aspiration biopsy of lymph nodes) groups. Propensity score matching (PSM) was performed to balance disparities between the two groups. Multivariate analysis with the Cox proportional hazards model was used to assess factors related to breast cancer‐specific survival (BCSS).

Results

Although the tumor size at time of presentation was decreasing over years, the rate of surgical axillary staging increased from 93.3% to 96.9%. The 5‐year BCSS rates of the whole cohort (before PSM) and matched cohort (after PSM) were 98.0% and 97.5%. Within the matched cohort, the BCSS was significantly longer in the staging group than in the non‐staging group (P < 0.001). However, surgical axillary staging did not benefit patients who were 50–79 years old, had tumor size < 1 cm, histological grade I disease, or favorable histological types (tubular/mucinous/papillary) in stratified analyses (P > 0.05). Race, marital status, hormone receptors, and chemotherapy were not associated with the favorable impact of surgical axillary staging on BCSS (P > 0.05).

Conclusion

Although surgical axillary staging remains important for T1 breast cancer patients treated with BCT, it might be unnecessary for patients with old age, small tumor, grade I disease, or favorable histological types.
Three-dimensional numerical modeling of gravity and magnetic anomaly in a mixed space-wavenumber domain
Authors: Dai Shikun , Zhao Dongdong , Wang Shunguo , Xiong Bin , Zhang Qianjiang , Li Kun , Chen Longwei , Chen Qingrui
Published: May 2019

Fast and accurate numerical modeling of gravity and magnetic anomalies is the basis of field-data inversion and quantitative interpretation. In gravity and magnetic prospecting, the computation and memory requirements of practical modeling is still a significant issue, which leads to the difficulty of using efficient and detailed inversions for large-scale complex models. A new 3D numerical modeling method for gravity and magnetic anomaly in a mixed space-wavenumber domain is proposed to mitigate the difficulties. By performing a 2D Fourier transform along two horizontal directions, 3D partial differential equations governing gravity and magnetic potentials in the spatial domain are transformed into a group of independent 1D differential equations wrapped with different wavenumbers. Importantly, the computation and memory requirements of modeling are greatly reduced by this method. A modeling example with 4,040,100 observations can be finished in approximately 28 s on a desktop using a single core, and the independent differential equations are highly parallel among different wavenumbers. The method preserves the vertical component in the space domain, and thus a mesh for modeling can be finer at a shallower depth and coarser at a deeper depth. In general, the new method takes into account the calculation accuracy and the efficiency. The finite-element algorithm combined with a chasing method is used to solve the transformed differential equations with different wavenumbers. In a synthetic test, a model with prism-shaped anomalies is used to verify the accuracy and efficiency of the proposed algorithm by comparing the analytical solution, our numerical solution, and a well-known numerical solution. Furthermore, we have studied the balance between computational accuracy and efficiency using a standard fast Fourier transform (FFT) method with grid expansion and the Gauss-FFT method. A model with topography is also used to explore the ability of modeling topography with our method. The results indicate that the proposed method using the Gauss-FFT method has characteristics of fast calculation speed and high accuracy.
The cytoneme connection: direct long-distance signal transfer during development
Authors: González-Méndez Laura , Gradilla Ana-Citlali , Guerrero Isabel
Published: May 2019

During development, specialized cells produce signals that distribute among receiving cells to induce a variety of cellular behaviors and organize tissues. Recent studies have highlighted cytonemes, a type of specialized signaling filopodia that carry ligands and/or receptor complexes, as having a role in signal dispersion. In this Primer, we discuss how the dynamic regulation of cytonemes facilitates signal transfer in complex environments. We assess recent evidence for the mechanisms for cytoneme formation, function and regulation, and postulate that contact between cytoneme membranes promotes signal transfer as a new type of synapse (morphogenetic synapsis). Finally, we reflect on the fundamental unanswered questions related to understanding cytoneme biology.
Superb microvascular imaging is a rational choice for accurate Bosniak classification of renal cystic masses
Authors: Mu Jie , Mao Yiran , Li Fangxuan , Xin Xiaojie , Zhang Sheng
Published: May 2019

Objective:

Bosniak classification system provides a fine imaging evaluation for the malignant cystic renal masses. Superb microvascular imaging (SMI) is a new ultrasonic technique which apply advanced clutter suppression to reflect microflow information. The aim of this study was to evaluate the performance of ultrasound Bosniak classification aided by SMI in diagnosis of cystic renal masses.

Methods:

By comparing with contrast-enhanced ultrasound (CEUS) and pathology, we evaluated the sensitivity, specificity and accuracy of conventional ultrasound and SMI combination in the diagnosis of renal cystic masses.

Results:

Color Doppler Flow image (CDFI) and SMI had significant difference in evaluation the blood flow and Bosniak classification for cystic renal mass of IIf, III and IV (p = 0.020). SMI was consistent with CEUS for cystic renal mass Bosniak classification of IIf, III and IV. Although, CEUS had highest sensitivity of 97.4%, SMI had the highest area under curve in differential diagnosis malignance from benign masses [area under curve = 0.869 (0.743 – 0.995), p < 0.001].

Conclusion:

SMI can display better in observing blood flow in septa and solid structures of renal cystic lesions compared with CDFI, thus, it can perform more accurate Bosniak classification for renal cystic mass. SMI and CEUS are consistent in Bosniak classification. Bosniak classification aided by SMI maybe an accurate non-invasive ultrasonic examination in distinguishing benign and malignant renal cystic lesions.

Advances in knowledge:

Conventional ultrasound had limited ability to distinguish malignance in Bosniak classifications IIf and III. SMI can display better in observing blood flow in septa and solid structures of renal cystic lesions compared with CDFI.
Two-Dimensional Phase Unwrapping via Balanced Spanning Forests
Authors: Herszterg Ian , Poggi Marcus , Vidal Thibaut
Published: May 2019

Phase unwrapping is the process of recovering a continuous phase signal from an original signal wrapped in the ([Formula: see text]] interval. It is a critical step of coherent signal processing, with applications such as synthetic aperture radar, acoustic imaging, magnetic resonance, X-ray crystallography, and seismic processing. In the field of computational optics, this problem is classically treated as a norm-minimization problem, in which one seeks to minimize the differences between the gradients of the original wrapped signal and those of the continuous unwrapped signal. When the [Formula: see text]–norm is considered, the number of differences should be minimized, leading to a difficult combinatorial optimization problem. We propose an approximate model for the [Formula: see text]–norm phase unwrapping problem in two dimensions (2D), in which the singularities of the wrapped phase image are associated with a graph where the vertices have −1 or [Formula: see text] polarities. The objective is to find a minimum-cost balanced spanning forest where the sum of the polarities is equal to zero in each tree. We introduce a set of primal and dual heuristics, a branch-and-cut algorithm, and a hybrid metaheuristic to efficiently find exact or heuristic solutions. These approaches move us one step closer to optimal solutions for 2D [Formula: see text]–norm phase unwrapping; such solutions were previously viewed, in the signal processing literature, as highly desirable but not achievable.
Ride Your Luck! A Field Experiment on Lottery-Based Incentives for Compliance
Authors: Fabbri Marco , Nicola Barbieri Paolo , Bigoni Maria
Published: May 2019

In a field experiment, we studied the performance of an incentive scheme that combines a lottery-based reward for compliance with probabilistic sanctions for noncompliance. For one month, bus passengers who purchased a ticket on board a subset of buses operating in a medium-sized Italian city participated in a lottery awarding a €500 prize. The remaining buses—otherwise identical—were used as controls. We observed the amount of tickets sold on treated and control buses over three months, before, during, and after the introduction of the lottery. Results show that treated buses sold significantly more on-board tickets than control buses during the lottery period. In our setup, the estimated extra revenues from the ticket sales caused by the introduction of the lottery fell short of the amount of the total prizes raffled off. However, the incentive scheme proved cost-effective because not all the lottery prizes were claimed by winners.

On the Role of a Market Maker in Networked Cournot Competition
Authors: Cai Desmond , Bose Subhonmesh , Wierman Adam
Published: May 2019

We study Cournot competition among firms in a networked marketplace that is centrally managed by a market maker. In particular, we study a situation in which a market maker facilitates trade between geographically separate markets via a constrained transport network. Our focus is on understanding the consequences of the design of the market maker and providing tools for optimal design. To that end, we provide a characterization of the equilibrium outcomes of the game between the firms and the market maker. Our results highlight that the equilibrium structure is impacted dramatically by the market maker’s objective—depending on the objective, there may be a unique equilibrium, multiple equilibria, or no equilibria. Furthermore, the game may be a potential game (as in the case of classical Cournot competition) or not. Beyond characterizing the equilibria of the game, we provide an approach for designing the market maker to optimize a design objective (e.g., social welfare) at the equilibrium of the game. Additionally, we use our results to explore the value of transport (trade) and the efficiency of the market maker (compared with a single aggregate market).
The experience of the non-medical prescriber in the emergency department in Ireland
Authors: Connor Roger , McHugh Áine
Published: May 2019

Aim:

this study set out to evaluate the position of the non-medical prescriber in the emergency department in Ireland. It aims to explore how the role is developing and determine possible barriers to role expansion.

Results:

six main themes were identified: the process of role development, changes in professional relationships, nurses' awareness of non-medical prescribing, role progression, the future of the role of the non-medical prescriber, and nursing management's understanding of the role.

Conclusion:

the findings suggest that despite major leaps in the progression of the non-medical prescriber role, many barriers remain. There have been great improvements in professional support from medical and pharmacy colleagues, but nurses themselves were identified as impeding the progression of the role.

Published: May 2019

O presente estudo tem como objetivo principal analisar os indicadores da qualidade dos serviços prestados pelos hotéis de Florianópolis por meio do site Booking.com (Booking online, 2017) e a partir dos resultados encontrados comparar as notas das cidades de Florianópolis e de Balneário Camboriú (Bordignon, Araujo, Meira & Anjos, 2016). A coleta de dados ocorreu no mês de junho de 2017, com análise de 81 hotéis de Florianópolis. Como resultado da pesquisa pôde-se verificar que os indicadores de qualidade dos hotéis de Florianópolis têm uma média razoável, com exceção da localização que conta com uma nota acima da média. Por outro lado, o serviço de internet wi-fi mostrou-se insuficiente para os hóspedes, o que representa um grande desafio, visto o uso significativo de dispositivos móveis nas viagens. Ao comparar os indicadores dos hotéis de Balneário Camboriú e de Florianópolis tem-se que a média geral de Florianópolis se mostra relativamente superior.
Self-Supervised Convolutional Neural Networks for Plant Reconstruction Using Stereo Imagery
Authors: Xia Yuanxin , D'Angelo Pablo , Tian Jiaojiao , Fraundorfer Friedrich , Reinartz Peter
Published: May 2019

Stereo matching can provide complete and dense three-dimensional reconstruction to study plant growth. Recently, high-quality stereo matching results were achieved combining Semi-Global Matching (SGM) with deep learning. However, due to a lack of suitable training data, this technique
is not readily applicable for plant reconstruction. We propose a self-supervised Matching Cost with a Convolutional Neural Network (MC-CNN) scheme to calculate matching cost and test it for plant reconstruction. The MC-CNN network is retrained using the initial matching results obtained from
the standard MC-CNN weights. For the experiment, closerange photogrammetric imagery of an in-house plant is used. The results show that the performance of self-supervised MC-CNN is superior to the Census algorithm and comparable to MC-CNN trained by a Light Detection and Ranging point cloud.
Another experiment is performed using stereo imagery of a field beech tree. The proposed self-training strategy is tested and has proved capable of identifying the drought condition of trees from the reconstructed leaves.
Masculinidades plurais e representações do feminino: arquitetura moderna e design em El hombre de al lado (2009)
Authors: Simião Suelen Caldas de Sousa
Published: May 2019

No longa-metragem argentino El Hombre de al Lado (2009) Leonardo, um designer, e Victor, seu vizinho, são antagonizados a partir da abertura de uma janela. A parede, rasgada pela necessidade de luz, é de Victor, e permite que este observe de perto o interior da Casa Curutchet, obra do arquiteto franco-suíço Le Corbusier e morada de Leonardo. Os embates desenvolvidos a partir dessa tensão inicial permitem o entendimento de confrontos de natureza política, social e cultural que se materializam também a partir da linguagem arquitetônica. Dessa forma, o presente trabalho tem como intuito problematizar de que maneira arquitetura, design e cultura material se relacionam, na película, a uma primazia do poder masculino e evidenciam relações de gênero - com raízes históricas no campo da arquitetura e do design-, ao mesmo tempo em que constrói e expressa diversos perfis de masculinidade.
O futuro da nação no ventre feminino: projetos políticos e literários sob a pena de Bernardo Guimarães
Authors: Silveira Daniela Magalhães
Published: May 2019

Parte importante dos contos e romances de Bernardo Guimarães foi publicada na década de 1870. Parece explícita sua dedicação, num momento especial da política brasileira voltada para as discussões em torno do final da escravidão, em elaborar personagens femininas capazes de projetar um futuro para o país. Para tanto, dedicou-se na construção de mulheres de origem social pobre, descendentes de africanos ou indígenas, mas que acabavam se adaptando ao estilo europeu e burguês ou que seriam criticadas justamente por resistir a esse modelo. A proposta deste artigo consiste em examinar algumas dessas personagens femininas, com atenção especial voltada para a elaboração de seus diálogos e perfis. Nesse percurso, pretendo destacar o modo como esse literato usou o seu ofício para intervir na construção de um Brasil sem escravos e formado por cidadãos "quase" brancos.

Published: May 2019

O atual momento brasileiro, de grave crise política, duvida da utilidade do conhecimento sobre o passado, levando muitos de nós, historiadores e historiadoras, a questionarmos o significado e o modo de fazermos História. Nesse sentido, valendo-me especialmente da Odisseia, mas também da discussão de Jeanne-Marie Gagnebin sobre o testemunho e ainda do relato de Primo Levi sobre Auschwitz, permito-me fazer uma reflexão alegórica sobre o que é narrar o passado, bem como sobre o público com quem desejamos compartilhar tal conhecimento. A discussão centra-se na noção de xenía, uma vez que estabelecemos uma relação dupla com aqueles que recebem nosso trabalho, os quais, dependendo exatamente da forma com que nos recebem, podem ou não pôr em xeque nossa tarefa.

Este artigo discute o conceito de "contrarrevolução" na historiografia daRevolução Cubana, inserindo nesse campo de discussão a eliminação dahomossexualidade como objetivo político dos revolucionários, sendo oshomossexuais considerados pelo regime como contrarrevolucionários porexcelência. A ideia de contrarrevolução é ainda muito restrita a oposiçõespolíticas contrárias Ã  revolução (imperialismo, luta armada e organizaçõespolíticas) negligenciando indivíduos que, malgrado não atuaremdeliberadamente contra o regime, foram combatidos comocontrarrevolucionários com base em critérios morais e sexuais. Adesconsideração dos homossexuais como contrarrevolucionários nahistoriografia deve-se ao próprio silêncio existente na historiografia emrelação à perseguição homofóbica promovida pelo regime de Fidel Castro.Dessa forma, serão abordados os critérios e atividades que têm definido ocampo dos opositores ao regime revolucionário na historiografia,apontando para as limitações e possibilidades do termo, propondo oalargamento do debate e aprofundando a compreensão do fenômeno, combase no delineamento da homossexualidade como lócuscontrarrevolucionário por parte da ideologia revolucionária instaurada em1959 em Cuba.

Este ensaio foi tecido a partir dos encontros de pesquisa promovidos pelo Núcleo de Estudos Transdisciplinares em Ensino, Ciência, Cultura e Ambiente (Nutecca), nos quais a busca por um ensino de qualidade têm se tornado o catalisador de discussões, sejam essas sobre questões relacionadas a Ambiente & Sociedade ou sobre nossas próprias práticas pedagógicas. O texto ora apresentado é um esforço colaborativo de organizar ideias a respeito de um conceito importante para a educação, mas que talvez tenha sido popularizado de uma forma que o banalizou. Trata-se do "professor reflexivoâ€, termo cunhado por Donald Schon no final do século passado, que diz respeito Ã  tríade ação-reflexão-ação, que deveria ser tratada como aspecto basilar da profissão docente.

Published: May 2019

O ensino da física ocorre, muitas vezes, de forma desarticulada da realidade vivida pelos alunos. Além disso, o conhecimento prévio dos mesmos é desconsiderado nas práticas pedagógicas. Nesse sentido, o trabalho em tela foi estruturado tendo as ideias prévias dos alunos como ponto de partida no estudo das leis de Newton, no primeiro ano do ensino médio. Buscando indícios de que a aprendizagem ocorreu de forma significativa, suas concepções prévias foram comparadas com o mapa conceitual que os mesmos elaboraram ao final da instrução. Disso, foi possível perceber a evolução conceitual dos mesmos, embora, ainda, outras ferramentas sejam importantes e necessárias para verificar indícios da aprendizagem dos conceitos desenvolvidos.

Os mapeamentos topográficos e batimétricos existentes para o Monumento Natural do Arquipélago das Ilhas Cagarras não atendem às necessidades de gestão devido à sua escala, apresentando cotas altimétricas dispersas e pouco detalhe. Por se tratar de uma Unidade de Conservação de proteção integral, ambiente sensível, o mapeamento por sensoriamento remoto é uma ótima ferramenta de levantamento sem interferência direta. O MDE batimétrico foi elaborado a partir do levantamento de campo realizado em barco inflável, numa malha amostral com espaçamento máximo de 50 metros entre linhas, com profundidades obtidas por ecobatímetro comercial acoplado a GPS, corrigidas para a variação de maré, e posterior modelagem da superfície contínua pelo interpolador Topo to Raster. Para o MDE topográfico, foram comparados três levantamentos: SRTM 30 m, ASTER GDEM e por estereofotogrametria, que foram comparados em relação as suas altitudes em 23 pontos de controle, e em suas aparências. O interpolador Topo to Raster gerou um erro médio quadrático submétrico (0,98 m). O MDE por estereofotogrametria captou melhor as amplitudes altimétricas, a sinuosidade do relevo e se mostrou mais próximo da geomorfologia original. O MDE final, corresponde a fusão do MDE batimétrico com o MDE topográfico estereofotogramétrico, e este trabalho apresenta uma metodologia de baixo custo e de ampla aplicação para geração de MDE em áreas marinhas protegidas.

Published: May 2019

Brucellosis is a reemerging infectious zoonotic disease of worldwide importance. In the Kurdistan Region of Iraq, it is a widely spread disease and remains a challenging health problem. This disease is mainly caused by Brucella melitensis, in human. For confirmation of these isolates, a study was performed, by isolation and molecular typing of Brucella Spp. from human patients in Rizgari Hospital at Erbil city (Iraq), between March 2014 and November 2016. One hundred sixty seven samples of blood collected from patients suspected for brucellosis, one hundred twenty one samples from these were recorded as genus of Brucella, using biochemical test and confirmed by applying polymerase chain reaction (PCR), using genus specific primer for omp31 gene which was specific for B. melitensis. These results support using molecular method that based on PCR as diagnostic test for the control of brucellosis in Erbil. Further studies are needed from different geographical areas of the country with different level of endemicity to plan and execute control strategies against human brucellosis.
Study the Changes in (pH, Turbidity, Hardness, and Total Organic Carbon) Levels of Water using Plant Membrane (Palm Leaves Powder) and Aquatic Plant System (Vine Stems)
Authors: Maaroof Ahmed A. , Sharif Fryad M.
Published: May 2019

Due to the increasing industrialization and urbanization, the requirement of clean water has been growing quite fast and it has the potential to keep increasing. There are many regions facing water crisis even some countries with a rich water source. In this study, three types of water (tap, ground, and light sewage) have been collected from different places in Ibrahim Ahmad site in Sulaymaniyah city/Kurdistan region – Iraq. The research studies the effects of plant membrane method, and aquatic plant system on the improvement of pH, turbidity, hardness, and total organic carbon (TOC) of water samples. In the plant membrane, palm leaves were crushed and used as a powder in filter bags; whereas in the aquatic plant system, vine stems were used by growing up the vines. The experimental results showed that the pH, hardness, turbidity, and TOC of water samples after using palm leaves powder and vine stems have been changed significantly with slight variation in some test results. The results of turbidity showed that using palm leaves powder as plant membrane was more effective than the vine stems in an aquatic plant system. On the other hand, the results of hardness and TOC tests of all water samples after using both methods proved that the vine stems method was more reliable than the palm leaves method. Finally, the pH results of all water samples after using both methods have been decreased to the normal range with a slight variation between the vine stems and palm leaves methods.

Published: May 2019

As a result of increasing population and building of new schools in Saudi Arabia, the demand for electricity is growing rapidly. In this context, the utilization of renewable energy resources such as solar energy appears to goal since it is abundant and holds huge ecological and economic promise. This study aims to provide a new entrance in school buildings’ design and construction by studying the current situation of energy consumption, the possibility of using solar cells, and the economics of its exploitation in school buildings. Interviews were conducted in school buildings at different levels in Arar city as a case study to collect data on energy consumption. Furthermore, a base case school building was selected for studying detailed energy consumption, and then, photovoltaic (PV) energy was proposed to use the on-grid system in accordance with governmental regulations. The study concluded that the use of PV energy in school buildings is economically feasible in addition to that more incentive from the government is needed for wide penetration use in Kingdom Saudi Arabia.
Theoretical Calculations for the Acidity of Cyanopolyynes HC2n+1N (n = 0–5) in Gas and Aqueous Phases Using Ab initio Methods
Authors: Abdallah Hassan H.
Published: May 2019

Cyanopolyynes have been found in the interstellar medium, cold dust cloud Taurus Molecular Cloud-1, and the Titan’s atmosphere. Theoretical calculations are carried out to predict gas and aqueous phase acidities of a series of cyanopolyynes acids. Two levels of theory were used in this study, with the combination of density functional theory, and Møller–Plesset perturbation (MP2) theory, MP2 methods with two types of basis set, namely, Pople’s 6–311++g (d, p) basis set and Dunning’s aug-cc-pVTZ basis set. The calculations of these molecules reveal that pKa values varying from 12.25 to 17.25 and indicate that the acidity of these molecules in aqueous phase increases whereas the acidity in gas phase decreases with an increasing chain length of these acids.

Customer Orientation in Share Tourism
Authors: Mattner Elisabeth , Peters Julia E.
Published: May 2019

Da Produkte zunehmend austauschbar werden und Märkte ihre Sättigungsgrenzen erreichen, ist die Kundenorientierung zu einem integralen Ansatz für den wirtschaftlichen Erfolg von Unternehmen geworden. Während die Kundenorientierung im traditionellen Unternehmensumfeld bereits umfassend erforscht wurde und eine Reihe von Messansätzen entwickelt worden sind, gab es bisher zur Kundenorientierung in der Sharing Economy noch keine Untersuchungen. Da Sharing Economy-Unternehmen im Vergleich zu Unternehmen mit traditionellem Unternehmenshintergrund unterschiedlich agieren, wird davon ausgegangen, dass nicht alle Indikatoren der Kundenorientierung in traditionellen Unternehmen auch für Unternehmen der Sharing Economy gelten. Daher wurden in dieser Untersuchung diese Unterschiede untersucht, um Indikatoren für die Kundenorientierung in der Sharing Economy vorzuschlagen und sie auf ihre praktische Relevanz in Peer-to-Peer-Märkten zu testen.
Destinationswerbung
Authors: Held Gudrun
Published: May 2019

Destinationswerbung ist gezielte Image-Werbung. Die Konstruktion eines touristischen Images basiert – unter anderem – auf einer möglichst anschaulichen Verarbeitung von sog. Identitätsmarkern, welche den beworbenen Raum im Werbetext gleichsam ‚ikonisch‘ repräsentieren sollen. Aus dem Blickwinkel der Linguistik und Semiotik wird an ausgewählten Beispielen untersucht, wie solche Identitätsmarker im multimodalen Text schlagkräftig in Szene gesetzt werden und welche Rolle Sprach-Bild-Kombinationen zur werbestrategischen Errichtung eines identitätsbezogenen ‚tourist gaze‘ spielen. Schlüsselwörter: Destinationswerbung, Printwerbung, Raum-Marketing, Imagekonstruktion, Identität/Identitätsmarker, Textlinguistik, Sprach-Bild-Texte, Multimodalität, Visualisierungsmethoden.
