Authors: Malhotra Poonam , Karamalakova Yana , Nikolova Galina , Singh Darshana , Kumar Raj
Published: December 2017

Gamma radiation generates free radicals in biological system by inducing cellular water radiolysis. If not neutralised, free radicals oxidise vital bio-macromolecules causing structural and functional impairment and contribute to cell death. In present study, free radical scavenging activities of a novel bacterial secondary metabolite, N-acetyl tryptophan glucoside (NATG) was assessed against gamma-radiation induced damage in vitro and in vivo models. Effect of irradiated NATG (UV and gamma radiation 8 Gy and 20 Gy) on its free radical (DPPH radicals) and SOD-like activity was evaluated using EPR spectrometry. To assess the effect of NATG irradiation on its antioxidant potential, EPR based ascorbate, PBN and NO radicals scavenging activities were evaluated in blood and spleen tissue of strain A male mice. Results of the study indicated significant (p < 0.05) increase in DPPH radicals scavenging ability of irradiated NATG as compared to un-irradiated NATG. Similarly, irradiated NATG exhibited significant (p < 0.05) elevation in SOD-like activity as compared to control. Subsequently, NATG treatment displayed enhanced antioxidant activity as evident by significant (p < 0.05) decline in ascorbate, PBN and NO radicals at 1 h and 2h in blood and spleen tissues homogenate of treated mice as compared to control group. In conclusion, NATG possesses significant free radicals scavenging and radio protective capabilities against gamma radiation induced oxidative stress.

Published: December 2017

The majority of high performance combat aircrafts presently being operated by Indian air Force are fitted with conventional oxygen systems in which a replenishable store of oxygen is carried, most often as liquid oxygen and the flow of gas to each crew member is controlled by an individual pressure demand regulator in which the oxygen is diluted with cabin air to provide breathing gas.Moreover, in-flight refueling capability of present generation fighter aircraft has made it possible to fly for long durations (6 to 8 hours). In such case, the oxygen source becomes one of the limiting factors. In order to meet this requirement, a large supply of Gaseous Oxygen (GASOX) or Liquid Oxygen (LOX) have proven to be a costly affair and the Onboard Oxygen Generating System (OBOGS) has become a very convenient and attractive proposal. The OBOGS employs molecular sieves to adsorb nitrogen from engine bleed air using pressure swing adsorption (PSA) technique, wherein two molecular sieve beds are continuously cycled between steps of pressurization (adsorption) and depressurization (desorption) to generate oxygen enriched breathing gas for aircrew. This paper describes the design of OBOGS using high performance Lithium based Low Silica X-type (Li-LSX) molecular sieves and its performance characteristics. It consists of two Zeolite beds filled with Li-LSX material which adsorbs nitrogen fromengine bleed air tapped from Environmental Control System pipe line. The two beds are cycled by a 5/2 way solenoid valve. The input air is supplied to the solenoid valve through a coalescent filter to reduce moisture from it and a pressure regulator is fitted at the upstream of solenoid valve to regulate the system pressure. The experimental setup for evaluation of OBOGS is also discussed. The OBOGS, presented in this paper, meets all the performance requirements as specified in MIL-C-85521 (AS).

Authors: Uthra K. , Kadirvelu K.
Published: December 2017

 Biosorption of Ni(II) was investigated in this study using dead biomass of gram positive (Bacillus subtilis) and gram negative (Pseudomonas aeruginosa).The effects of pH, initial adsorbent dosage, initial metal ion concentration, contact time and temperature were studied in batch experiment. A contact time of 40 min, pH 5.0 and temperature 30oC were found to be optimum. Nickel removal decreased from 77 to 45% as the concentration increased from 50 to 250 mg/L. The Ni(II) removal increased from 45 to 75% as adsorbent dose increased from 0.25 to 1.5 g/L. The Langmuir and freundlich models for dynamics of metal of metal ion uptake proposed in this work fit the experimental data reasonably well. The adsorption capacity (Qo) calculated from Langmuir isotherm was 89.08 mg for Ni (II). 
Real-time Accurate Runway Detection based on Airborne Multi-sensors Fusion
Authors: Zhang Lei , Cheng Yue , Zhai Zhengjun
Published: December 2017

Existing methods of runway detection are more focused on image processing for remote sensing images based on computer vision techniques. However, these algorithms are too complicated and time-consuming to meet the demand for real-time airborne application. This paper proposes a novel runway detection method based on airborne multi-sensors data fusion which works in a coarse-to-fine hierarchical architecture. At the coarse layer, a vision projection model from world coordinate system to image coordinate system is built by fusing airborne navigation data and forward-looking sensing images, then a runway region of interest (ROI) is extracted from a whole image by the model. Furthermore, EDLines which is a real-time line segments detector is applied to extract straight line segments from ROI at the fine layer, and fragmented line segments generated by EDLines are linked into two long runway lines. Finally, some unique runway features (e.g. vanishing point and runway direction) are used to recognise airport runway. The proposed method is tested on an image dataset provided by a flight simulation system. The experimental results show that the method has advantages in terms of speed, recognition rate and false alarm rate.
HeW: AHash Function based on Lightweight Block Cipher FeW
Authors: Kumar Manoj , Dey Dhananjoy , Pal Saibal K , Panigrahi Anupama
Published: December 2017

A new hash function HeW: A hash function based on light weight block cipher FeW is proposed in this paper. The compression function of HeW is based on block cipher FeW. It is believed that key expansion algorithm of block cipher slows down the performance of the overlying hash function. Thereby, block ciphers become a less favourable choice to design a compression function. As a countermeasure, we cut down the key size of FeW from 80-bit to 64-bit and provide a secure and efficient key expansion algorithm for the modified key size. FeW based compression function plays a vital role to enhance the efficiency of HeW. We test the hash output for randomness using the NIST statistical test suite and test the avalanche effect, bit variance and near collision resistance. We also give the security estimates of HeW against differential cryptanalysis, length extension attack, slide attack and rotational distinguisher.

Along with the change in information and communication technology, learning methods are also changing. One of the new and fastest growing learning models is m-learning. The m-learning is often defined as a learning environment in which students and instructors can access learning system over wireless network at anytime, anywhere using mobile devices. According to Koole's definition, m-learning; "Is a process of interaction of mobile technologies, learning capacities, and social aspects of the learners”. Use of m-learning in nursing education is increasing day by day. It’s known that these technologies are used in nursing education in many countries, although there is no clear information about the number of schools that use mobile devices in nursing education. M-learning in nursing education; supports learning, provides up-to-date accurate information and has important information potential such as patient safety, support for evidence based practice, development of decision-support systems.

Authors: Caponetti Diana , Trombetta Alessandro , Trombetta Giulio
Published: December 2017

We define and study the moduli d(x, 𝓐, D) and i(x, 𝓐,D) related to monotonicity of a given function x of the space L
0(Ω) of real-valued “measurable” functions defined on a linearly ordered set Ω. We extend the definitions to subsets X of L
0(Ω), and we use the obtained quantities, d(X) and i(X), to estimate the Hausdorff measure of noncompactness γ(X) of X. Compactness criteria, in special cases, are obtained.

Hybrid ANN optimized artificial fish swarm algorithm based classifier for classification of suspicious lesions in breast DCE-MRI
Authors: Janaki Sathya D , Geetha K
Published: December 2017

Automatic mass or lesion classification systems are developed to aid in distinguishing between malignant and benign lesions present in the breast DCE-MR images, the systems need to improve both the sensitivity and specificity of DCE-MR image interpretation in order to be successful for clinical use. A new classifier (a set of features together with a classification method) based on artificial neural networks trained using artificial fish swarm optimization (AFSO) algorithm is proposed in this paper. The basic idea behind the proposed classifier is to use AFSO algorithm for searching the best combination of synaptic weights for the neural network. An optimal set of features based on the statistical textural features is presented. The investigational outcomes of the proposed suspicious lesion classifier algorithm therefore confirm that the resulting classifier performs better than other such classifiers reported in the literature. Therefore this classifier demonstrates that the improvement in both the sensitivity and specificity are possible through automated image analysis.
Diet composition of syntopically breeding falcon species Falco vespertinus and Falco tinnunculus in south-western Slovakia

Published: December 2017

The red-footed falcon and Eurasian falcon represent two syntopical falcon species. While the Eurasian falcon is considered a common and numerous species in Slovakia, the red-footed falcon population has undergone a considerable decline during the past few decades. Nowadays it nests in a single locality in Slovakia, the Sysľovské polia Special Protection Area, which forms the northern and fragmented border of the species distribution area in Europe. By analysing prey remains from 9 nests (from 1998, 2001, 2013, 2014 and 2016), we identified 433 prey items belonging to 35 taxa and 9 orders. Every year, invertebrates made up the major part of the diet spectrum, in which Calosoma auropunctatum, Tettigonia viridissima, Zabrus tenebrioides, Anisoplia aegetum and Rhizotrogus sp. were the most frequent species of prey. Of the vertebrates, Microtus arvalis was the most hunted prey species. By supplementary analysis of 21 photos, we extended our knowledge on the diet by other 6 taxa. The peak of the M. arvalis population growth in 2014 did not manifest itself in the red-footed falcon diet composition. In 1998, 2014 and 2016 we also studied the diet of a syntopical species, the Eurasian kestrel. By analysing prey remains in 22 nests, we identified 1,151 prey items belonging to 37 taxa and 7 orders. In 1998 and 2014 vertebrates predominated, especially the common vole, however in 2016 invertebrates prevailed. This fact could be a reaction to the M. arvalis population peak in 2014 and its decline in 2016. These results suggest that this variability in the foraging behaviour of the Eurasian kestrel, an opportunistic predator, during the hunting of invertebrates increases the diet similarity and overlapping of the food niche of both studied falcon species.
Trend in an isolated population of the red-footed falcon (Falco vespertinus) at the edge of its breeding range (south-western Slovakia)

Published: December 2017

The population of the red-footed falcon in Slovakia inhabits the north-western edge of the species' breeding range. This breeding population is relatively small and came near to extinction during the population decline of this species in central Europe in recent decades. Thanks to increasing numbers of breeding pairs in Hungary, the Slovak population began to grow again. Moreover, some differences in breeding biology associated with breeding in nest boxes were found. Here we describe the dependence of the small isolated breeding population in Slovakia on the core population in the more eastern parts of the Carpathian Basin, and the impact of supporting activities (nest boxes) on this raptor species in Slovakia.

Although overall survival rate for patients with thyroid cancer (TC) is high, there is an alarming 10-year recurrence rate of up to 30% conferring a ~50% survival among these high-risk patients. The BRAFV600E mutation is estimated to be present in over 50% of papillary thyroid cancer (PTC) cases besides being associated with carcinogenesis and poor prognosis. We assessed the status of NF-κB, Ki-67, cyclin D1 and BRAFV600E in TC tissues and TC cell lines using immunohistochemistry and Western blot analysis. Concurrently, we evaluated the outcomes of combined targeting of the proteasome pathway in addition to selective BRAF inhibitors in cases of PTC. In this study, BRAFV600E-bearing TC cells were treated with BRAFV600E inhibitor, Vemurafenib alone or in combination with the proteasome inhibitor, Bortezomib. The combination of both drugs showed synergistic effects as evidenced by cell growth inhibition (P < 0.05), increased G2-phase cell cycle arrest and induced apoptosis (P < 0.05). In our TC xenograft model, the combination of Vemurafenib and Bortezomib significantly reduced tumor size (P < 0.05) and expression of the markers of cell growth and proliferation, Ki-67 and cyclin D1 (P < 0.001), when compared to monotherapy. Further analysis demonstrated that treatment with Bortezomib sensitized TC cells to Vemurafenib via mitochondrial dysregulation and apoptosis of TC cells, as evidenced by the increase in the expression of p53, Noxa protein, the loss of mitochondrial membrane potential, cytochrome c release and Poly (ADP-ribose) polymerase cleavage. Our results demonstrate a strong clinical potential for the combination of the Bortezomib and the BRAF inhibitor Vemurafenib as an efficient therapeutic approach for the treatment of TC.

Published: December 2017

Mechanical circulatory support can prevent multi-organ failure and death in patients with advanced cardiogenic shock. Here we describe our experience using extracorporeal membrane oxygenation (ECMO) for treatment of advanced cardiogenic shock which has been used by our team for daily routine care in more than 200 patients during the last five years at the Penn State Medical Center.Venoarterial (VA) ECMO has been used as a viable therapeutic option for advanced cardiogenic shock as a bridge to recovery (BTR) or bridge to next decision (BTD). Our group performed a retrospective review of data from 155 patients from our single center cohort treated with VA ECMO for advanced cardiogenic shock. After successful ECMO treatment, the one year survival rate of patients with ischemic heart disease was 73.7 %, and the one year survival for patients with non-ischemic heart disease was 75%.

Published: December 2017

Background: Blood transfusions are the most common type of tissue and organ transplantation. Perioperative and postoperative transfusions may cause morbidity and mortality and transfusion should based on only hematocrit values but also on hemodynamic and clinical parameters of the patient, which cannot be ignored.Methods: A prospective study was conducted between January 2015 and October 2016 with adult patients undergoing elective open heart surgery. In these patients, a protocol was established, and patients were divided into two groups as transfusion (-) and transfusion (+). In the first 24 hours in the intensive care unit, patients’ drainage, 24-hours urine output, awakening and extubation times, and lactate and bilirubin levels in arterial blood gases were recorded. Thirty-day mortality and morbidity, and hemodynamic and clinical data were compared between these two groups.Results: We have performed a total of 138 cases; no blood and blood products were transfused in 71% (n = 98), and in 29.0% (n = 40) blood and blood products were transfused. Thirty-day mortality and morbidity (arrhythmia, infectious and pulmonary morbidity, myocardial infarction, cerebrovascular accident, renal dysfunction, sternal revision) were compared between these two groups and no statistically significant difference was observed. Patients’ awakening, extubation time, cardiopulmonary bypass period, cross-clamp time, and days in intensive care unit and hospital were compared, and there was no statistically significant difference between the two groups. Conclusion: In this study, we conclude that open heart surgery without blood transfusion may be accomplished with decent peri/postoperative management. The patients who did not receive any blood or blood products were not compromised clinically or hemodynamically. No extra morbidity and mortality were seen in the non-transfusion group. Transfusion decision was based on clinical and hemodynamic parameters such as persistent hypotension or tachycardia, hyperlactatemia, low urine output, and anemic symptoms.
A Shift to the Left: Teaching the Craft of Cardiac Surgery
Authors: Tribble, MD Curt
Published: December 2017

I was in Chicago in 1987 when Dr. Shumway delivered his American Association for Thoracic Surgery (AATS) presidential address, and, like most in the audience, I knew he was correct. Having had the privilege of getting to do a lot of thoracic and cardiovascular surgery in my surgical training, I was preparing myself to make my own move to the left side of the operating table. In fact, I had already resolved that I would make my own “shift to the left” very soon after that meeting in 1987, hoping to become, like Dr. Shumway, the best first assistant I could be. Over thirty years later, I have never looked, nor moved back. However, making this move to the left side of the table – to teach surgical residents how to operate – is challenging for many surgeons in academic environments. In considering the challenges, we must remember that those of us who have agreed to teach our protégés have an obligation both to them, and to their future patients, to help them become safe, capable cardiothoracic surgeons

Assembling Aarhus West
Authors: Krogh Mads
Published: December 2017

Aarhus West rap music constitutes a dominant trend within Danish hip-hop. Throughout the 2000s, a number of rappers with a common background in a specific area in the western part of Aarhus rose to national fame, setting sales records while bringing issues of ethnic and socio-geographical marginalization into the Danish popular music and cultural mainstream. In this article, I present Aarhus West as a case study to discuss (sub)generic developments within hip hop as a global phenomenon. While considering current developments in popular music genre theory, I argue that predominant notions of “glocalized” rap as ‘resistance vernaculars’ or ‘global noise’ (cf. Hawkins et al. 2004, Mitchell 2001) risk maintaining overly homogenous understandings of genre. In particular, I appeal to the Deleuzian concept of assemblage to highlight heterogeneity – and more specifically continuous de- and re-territorialization within a heterogeneous milieu of rap music, hip hop culture, social, ethnic and geographical conditions, media, political and commercial interests – as a key issue in understanding musico-generic development, persistence and strength.

Neste trabalho foi desenvolvido e caracterizado filmes biodegradáveis à base de amido de feijão macáçar, plastificado com glicerol e com a mistura glicerol e ácido acético glacial (HAc). Os filmes foram obtidos por casting empregando amido de feijão macáçar (3 g/100 g de solução filmogênica) e diferentes concentrações do plastificante glicerol (20 e 30 g/100 g de amido) e da mistura glicerol e ácido acético glacial, nas proporções de 20 g e 10 g/100 g de amido, respectivamente. Os filmes apresentaram boas continuidade, uniformidade, manuseabilidade, transparência e, ainda, ausência de bolhas e rachaduras na superfície. O aumento da quantidade de solução filmogênica nas formulações, de 0,23 para 0,46 g/cm2, afetou positivamente a espessura, a gramatura e a densidade, mas não alterou a umidade e transparência dos filmes. O carácter hidrofílico dos filmes cresceu com aumento da quantidade de plastificante.

Why Context Matters: Social Inclusion and Multilingualism in an Austrian School Setting
Authors: Jessner Ulrike , Mayr-Keiler Kerstin
Published: December 2017

This article draws attention to language choice and language use of Austrian bi- and multilingual school children. We explore some implications of their linguistic practices with regard to social inclusion in an Austrian educational school setting. Pursuing a Dynamic Systems and Complexity Theory approach, we hypothesise that before language users actually use a language within a certain context, they have to evaluate the respective communicative situation by taking multiple contextual factors into consideration, meaning language users choose to use, or not to use, a language based on the socio-contextual information at hand. We consider these contextual factors to be most relevant as they provide the basis on which speakers can actually make use of a certain language within a given context. By drawing on examples of empirical data obtained through a language background survey, we examine some of the complex and dynamic interactions of contextual parameters influencing language choice and language use in the formal educational setting of classroom instruction. Based on the results of this study, we display a selection of the dynamic and complex interactions of pupils’ language use in one specific context as well as their language preferences and how these relate to social inclusion.

Introdução: A doença celíaca é caracterizada como uma enteropatia autoimune, desencadeada pela ingestão do glúten. A adição de partes não convencionais dos vegetais propicia produtos com melhor qualidade nutricional. Diversos nutrientes são encontrados na semente de abóbora, em especial lipídios, proteínas e fibras alimentares. Na casca têm destaque as fibras, ácido ascórbico e cálcio. Objetivo: Desenvolver e avaliar a aceitabilidade sensorial de formulações de pães sem glúten com diferentes teores de farinha da semente de abóbora e farinha da casca de abóbora, bem como determinar a composição físico-química das farinhas. Material e Métodos: Após a elaboração das farinhas, foram preparadas quatro formulações de pães adicionadas de farinha de semente e casca de abóbora. Determinou-se a composição físico-química nas farinhas e foi realizada análise sensorial dos pães com 50 provadores não treinados. Resultados: A farinha de semente de abóbora apresentou maiores teores de lipídios, proteínas e fibras, enquanto maiores teores de umidade, cinzas e carboidratos foram constatados na farinha de casca de abóbora, sendo estatisticamente significativos. De acordo com a análise da composição nutricional dos pães, as formulações adicionadas de farinha de semente apresentaram teores maiores de proteínas, lipídeos e fibras do que as adicionadas com farinha da casca. Na análise de aceitabilidade não houve associação estatística significativa entre as formulações com diferentes percentuais das farinhas. Os pães adicionados com farinha de semente obtiveram melhores resultados no teste de intenção de compra quando comparados aos pães com farinha da casca. Conclusão: As farinhas elaboradas mostram-se viáveis para aplicação em produtos de panificação, pois aumentam a qualidade nutricional dos produtos. Apesar disso, fazem-se necessários ajustes para que a farinha da casca de abóbora tenha melhor aceitação por parte dos consumidores.

A Multivariate Analysis of Writing Skills in BSW Case Study Papers
Authors: Cronley Courtney , Kilgore Christopher , Daniels-Lerberg Tracey
Published: December 2017

This study assesses BSW student writing (N=87, 35.2% African American) on a case study writing assignment in a U.S. school of social work. Papers were scored for response to rhetorical situation, organization, grammar, and adherence to the Publication Manual of the American Psychological Association. We then predicted students' scores based on demographic factors using multivariate linear regression. Descriptive statistics showed that students scored lower in response to rhetorical situation (M=2.20, SD=.78, scale of 1–5) than in organization (M=2.60, SD=.82), style (M=2.57, SD=1.03), or grammar (M=2.66, SD=.77). In the multivariate models, grade point average and race were the strongest predictors of scores. Results suggest that baccalaureate social work program directors may consider increasing writing support and process assignments and examining how defining good writing reinforces sociopolitical bias in social work education.

Authors: Mahajan Neetin P. , Pawar Eknath D. , Supe Amit C. , Mangukiya Hitesh J.
Published: December 2017

Background: Distal tibial diaphyseal fractures are known for its various challenges that orthopaedicians face while treating. While performing surgery, many principles of fixations are needed to be properly addressed. This study was undertaken to know the efficiency of closed reduction, polar screws and tibia interlocking nail fixation at our Institute.

Methods: The data, which were collected from the medical records and Department digitalised storage system and from the HMIS patient filing system, included age, sex, date of admission, type of admission (elective versus emergency), and AO classification of distal tibial fracture admitted in Orthopaedics Department from 2007 to 2013. Analyses of 46 cases, 34 males and 12 females, were made to find out the functional, radiological outcome, associated complications in treating distal tibia with ILN. During Analysis, association of the single event with the variables was estimated using Relative Risk, with a 95% confidence interval and P value of <0.05 was considered significant.

Results: The average time to union of the closed fracture was 15.4 weeks (range: 12–28 weeks). The healing times for the primarily nailed compound Grade I averaged 17.8 weeks (range: 15-34 weeks). Complications of delayed union occurred in 3 cases, and two cases of non-union. Infection in 6 cases (5 superficial, 1 deep), screw breakage in 4 cases and 3 cases of significant malalignment. The final functional outcome of 33 patients had excellent results, 11 had good results and 2 had fair results as determined by criteria of Johner and Wruh.

Conclusions: The dynamic osteosynthesis of distal tibia by interlocking nail and judicious use of poller screws is an effective alternative for the treatment of distal metaphyseal tibial fractures.

Teoria constitucional em mutação: perspectivas do constitucionalismo contemporâneo frente aos desafios da globalização e transnacionalidade / Constitutional theory changing: perspectives of contemporary constitutionalism to the challenges of globalization and transnationality
Authors: Ferreira Francisco Gilney Bezerra de Carvalho , Lima Renata Albuquerque
Published: December 2017

RESUMO O presente trabalho busca discutir a problemática vivenciada hodiernamente no que tange aos novos rumos do constitucionalismo contemporâneo a partir da observação do fenômeno da globalização e transnacionalização da dimensão jurídica. A análise é feita levando em consideração a trajetória de evolução constitucional e o atual contexto de mitigação da soberania estatal. A Constituição, após assumir o destaque de norma suprema e central dentro do ordenamento jurídico, passa a não mais ser um instrumento suficiente para regular as complexas relações que se desenvolvem em ambiente global e que atravessam as fronteiras nacionais. Tendo em vista a necessidade de uma urgente readequação da teoria constitucional, torna-se necessário buscar alternativas para responder ao novo cenário de realidade transnacional. Para a elaboração deste artigo foi utilizada uma pesquisa teórico-bibliográfica e documental, na qual se fez basilar o estudo de livros, artigos e documentos legislativos pertinentes. Do ponto de vista de abordagem do caso, pode-se caracterizar a pesquisa como qualitativa, com exame dos acontecimentos que se dão em sociedade, os quais afetam direta ou indiretamente os indivíduos enquanto membros de uma comunidade global.Palavras-Chave: Constitucionalismo; globalização; transnacionalidade. ABSTRACT This paper discusses the problems experienced in our times with respect to the new directions of contemporary constitutionalism from the observation of the phenomenon of globalization and transnationalization of the legal dimension. The analysis is done taking into account the path of constitutional development and the current context of mitigation of state sovereignty. The Constitution, after taking the highlight of supreme and central law within the legal order, shall not be a sufficient instrument to regulate the complex relationships that develop into global environment and cross national borders. In view of the need for urgent readjustment of constitutional theory, it is necessary to seek alternatives to respond to the new scenario of transnational reality. For the preparation of this article was used a theoretical-bibliographical and documentary research, which has important the study of books, articles and relevant legislative documents. From the point of view of case of the approach, it is considered as a qualitative research, from the point of view of the case of the approach, it is considered as qualitative research, with examination of the events that take place in society, which directly or indirectly affect individuals as members of a global community.Keywords: Constitucionalism; globalization; transnationality.
Racismo institucional e as oportunidades acadêmicas nas IFES
Authors: Barbosa e Silva Leonardo
Published: December 2017

Desde 2012, após a aprovação da Lei Federal 12.711, as universidades federais implementaram reservas de vagas sociais e raciais nos processos seletivos para ingressantes. O avanço desta medida já se encontra registrado e reconhecido como importante movimento nacional de democratização do acesso. Todavia, interessa saber sobre as condições no interior das IFES, se há maiores dificuldades para negros e negras acessarem oportunidades acadêmicas, em especial da Universidade Federal de Uberlândia (UFU), constituindo aquilo que se poderia chamar de racismo institucional. Para tanto, fez-se uso de pesquisa documental, acessando a base de dados da IV Pesquisa Nacional de Perfil de Graduandos das IFES (Fonaprace/Andifes) que foi submetida a uma análise quantitativa valendo-se de software estatístico (SPSS®) e a uma análise qualitativa. De forma geral, foi utilizado o critério comparativo entre a composição demográfica nos programas acadêmicos, na instituição, no estado e no país. Como resultado, percebeu-se a manifestação de racismo institucional na distribuição das oportunidades acadêmicas nas IFES e na UFU.

Published: December 2017

Background and Purpose: There is growing evidence that simulation testing is appropriate for assessing nursing competence. We compiled evidence on the validity and reliability of the Nursing Performance Profile (NPP) method for assessing competence. Methods: Participants (N = 67) each completed 3 high-fidelity simulation tests; raters (N = 31) scored the videotaped tests using a 41-item competency rating instrument. Results: The test identified areas of practice breakdown and distinguished among subgroups differing in age, education, and simulation experience. Supervisor assessments were positively correlated, r = .31. Self-assessments were uncorrelated, r = .07. Inter-rater agreement ranged from 93% to 100%. Test–retest reliability ranged from r = .57 to .69. Conclusions: The NPP can be used to assess competence and make decisions supporting public safety.
Inter-Rater Reliability and User-Friendliness of the Delirium Observation Screening Scale
Authors: Mueller Gerhard , Wetzlmair Jutta , Lechleitner Monika , Schulc Eva
Published: December 2017

Background and Purpose: Delirium is a common and often unrecognized complication of hospitalized elderly patients. Currently, there is no evidence for inter-rater reliability studies between registered nurses in the literature. Furthermore, the user-friendliness of the Delirium Observation Screening Scale (DOSS) has not been tested in Austria. Methods: A quantitative cross-sectional design with a convenience sample of 141 patients and 36 nurses in an Austrian hospital. Results: Analysis of rater-agreement and inter-rater reliability on item level, total score as well as category of delirium risk demonstrated very high agreement. In contrast, no or only fair kappa coefficient were determined. The user-friendliness of the scale was partially satisfactory. Conclusions: The very high absolute agreement speaks for the reliability of DOSS although the kappa paradox became obvious. The results of the presented study relate only to the tested setting.
