O ESTUDO DA REPRESENTATIVIDADE RACIAL E DE GÊNERO NOS CURSOS DE LICENCIATURA DOS INSTITUTOS FEDERAIS DE MINAS GERAIS
Authors: Ziviani Denise Conceição Das Graças , Estevam Vanessa da Silva
Published: February 2017

Este estudo faz alusão às relações raciais, de gênero e classe socioeconômica do alunado dos cursos de Licenciatura, tendo como espaço empírico os Institutos Federais de Minas Gerais. A partir de dados fornecidos pela Pró-Reitoria e pelo IFMG campus Ouro Preto, na faixa temporal de 2011 a 2015 foi possível constatar que os IFs mineiros dispõem de uma segregação racial por área do conhecimento, sendo que a maioria do alunado cursa Licenciatura na área de Humanas e os estudantes que se declararam brancos cursam Licenciatura na área de exatas. Segundo dados obtidos, mais de 90% frequentaram escolas públicas durante o ensino médio e prestaram vestibular tradicional para ingressarem no ensino superior. Em contraposição, ainda é desconhecido a representatividade por sexo, devido a falta de coleta, armazenamento e tratamento dessa informação por parte da instituição, que desconsidera a importância da política de educação e gênero.

Published: February 2017

Introduction: Alcohol use disorder is a relapsing and remitting disorder. Preventing alcohol relapses has been a difficult task. The available drugs do not have adequate outcome in diverse needs. Topiramate, a GABAergic anticonvulsant, has been useful for the prevention of alcohol relapse as demonstrated in western studies. We compared the efficacy of Topiramate at 100mg with Naltrexone 50 mg in preventing relapse among Nepalese alcohol dependence patients.Methods: Following an inpatient alcohol detoxification, 37 patients taking Topiramate 100 mg and 41 patients taking Naltrexone 50 mg were followed up as outpatients at 1, 4, 8 and 12 weeks in order to monitor their abstinence period, craving for alcohol and alcohol use pattern.Results: At the end of 12 weeks follow up, Topiramate is as good as Naltrexone 50 mg in terms of maintaining abstinence (27% vs 31.7%, p=0.651) and reducing the daily alcohol intake. Topiramate is better than Naltrexone in decreasing craving at 12 wks (p=0.015).Conclusion: Topiramate 100 mg is equally efficacious to Naltrexone 50 mg in reducing alcohol craving and maintaining abstinence.
Challenging Historical Frameworks: Aboriginal Rights, The Trickster, and Originalism
Authors: Borrows John
Published: February 2017

The Supreme Court of Canada has created a narrow framework for recognizing Aboriginal and treaty rights in Canada's Constitution by reference to historic moments of contact, assertions of sovereignty, and negotiated agreements. This approach has placed historical inquiries that search for “original” understandings at the centre of the court's jurisprudence. This article argues that law should not be equated with history in this way. It has severely disadvantaged Indigenous peoples. As a “living tree,” Canadian constitutional law should regard the “past” as a grab bag of possibilities for present reasoning, rather than as a constraint on present developments, because they do not have analogues in a bygone era.
Intersections of Indigenous and Environmental History in Canada
Authors: Leddy Lianne C.
Published: February 2017

The relationship between environmental and Indigenous history is complex and still evolving. As the Truth and Reconciliation Commission of Canada reminds us, land dispossession is not simply an historical phenomenon, but one that continues to affect Indigenous communities and Indigenous-settler relations in the present day. This article takes an historiographical approach to examining issues related to decolonizing research practices that privilege Indigenous perspectives, differing cultural views of resources and the environment, and the colonizing impacts of industrial and extractive practices on Indigenous communities. It argues that more scholars should incorporate gendered perspectives, and that they analyze Indigenous history in ways that respect our own national boundaries on Turtle Island.
Seeking Factors to Increase the Public's Acceptability of Road-Pricing Schemes
Authors: Bueno Paola Carolina , Gomez Juan , Vassallo Jose Manuel
Published: February 2017

User acceptability has become a critical issue for the successful implementation of transport pricing measures and policies. Although several studies have addressed the public acceptability of road pricing, little evidence can be found of the effects of pricing strategies. The acceptability of alternative schemes for a toll network already in operation is an issue to be tackled. This paper contributes to the limited literature in this field by exploring perceptions toward road-pricing schemes among toll road users. On the basis of a nationwide survey of toll road users in Spain, the study developed several binomial logit models to analyze user acceptability of three approaches: express toll lanes, a time-based pricing approach, and a flat fee (vignette) system. The results show notable differences in user acceptability by the type of charging scheme proposed. Express toll lanes were more acceptable by travelers who perceived greater benefits from saving travel time. The acceptability of time-based approaches (peak versus off-peak) decreased for users who felt forced to use the toll road, whereas this was not an aspect that significantly influenced users’ support for flat fee schemes. In addition, a flat fee strategy was more acceptable for long-distance trips and truck drivers who regularly used the toll facilities. The results from this analysis can inform policy makers and planners for the promotion of more efficient, socially inclusive, and publicly acceptable road-pricing schemes.

A new two-dimensional (2D) bismuth(III) coordination polymer, {[Bi( μ-C4H4O6)(NO3)(H2O)]. 4H2O}∞ (1), resulted from the hydrothermal reaction of tartaric acid and Bi(NO3)3.5H2O. The compound was characterized by elemental analysis and IR spectroscopy, and by X-ray structure analysis. Compound 1 crystallizes in the orthorhombic space group P212121. Tartrate as a multidentate ligand bridges four symmetry related bismuth(III) ions in an O,O’ fashion to form an infinite 2D coordination network in the (0 0 1) plane. Thermal decomposition of 1 in the presence of polyethylene glycol led to nano-particles of Bi2O3. Powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the Bi2O3 powders. The XRD pattern confirmed the formation of the α-polymorph of Bi2O3.

Published: February 2017

5 regioisomers of N,N-dimethyl(((phenylethynyl)phenyl)ethynyl)aniline (nDPEA) were synthesized by Sonogashira cross-coupling reaction and well characterized. The spectroscopic properties of these regioisomers were studied and discussed. nDPEAs 1b and 1d show shorter λabs and lower ΦF due to meta- branching disrupts the π-electron conjugation. nDPEAs 1c and 1e show shorter λabs because of their steric effects. Based on the high ΦF values of 1a, 1c and 1e, the π-electrons of these nDPEAs are delocalized over the whole molecules. These results are consistent with the theoretical calculations. Time dependent density functional theory computations were performed with the B3LYP or CAM-B3LYP for the identification of vertical transitions in 1a-1e. The predicted and observed absorption spectra of 1a-1e are well consistent.

The composition and microstructure of different CaCO3-Ca2SiO4-carbon nanotube composites have been studied. Materials have been characterized by X-ray diffraction (XRD), high resolution scanning electron microscopy (SEM), thermogravimetric/differential thermal analysis (TG/DTA), and Fourier-transform infrared (FTIR) spectroscopy. The morphology and structure of the inorganic systems are affected by the presence of multiwall carbon nanotubes (MWCNT) during the hydration processes and the nature of the MWCNT/SDS interface plays a role in the curing stages of the composite enhancing the growth of calcium silicate.
Directional prediction of stock prices using breaking news on Twitter
Authors: Alostad Hana , Davulcu Hasan
Published: February 2017

Stock market news and investing tips are popular topics in Twitter. In this paper, first we utilize a 5-year financial news corpus comprising over 50,000 articles collected from NASDAQ website matching 30 stock components in Dow Jones Index (DJI) to train a directional stock price prediction system based on news content. Next, we proceed to show that information in articles indicated by breaking Tweet volumes leads to a statistically significant boost in hourly directional prediction accuracies for the DJI stock prices mentioned in these articles. Secondly, we show that using document-level sentiment extraction does not yield a statistically significant boost in the directional predictive accuracies in the presence of other 1-gram keyword features. Thirdly we test the performance of the system on several time-frames and identify 4 hour time-frame for both the price charts and for Tweet breakout detection as the best time-frame. Finally, we develop a set of price momentum based trade exit rules to cut losing trades early and to allow winning trades run longer. We show that the Tweet volume breakout based trading system with price momentum based exit rules not only improve the winning accuracies and the return on investment, but they also lower the maximum drawdown and achieve highest overall return over maximum drawdown.
A modular architecture for intelligent agents in the evented web
Authors: Sánchez-Rada J. Fernando , Iglesias Carlos A. , Coronado Miguel
Published: February 2017

The growing popularity of public APIs and technologies such as web hooks is changing online services drastically. It is easier now than ever to interconnect services and access them as a third party. The next logical step is to use intelligent agents to provide a better user experience across services, connecting services with smart automatic behaviors or actions. In other words, it is time to start using agents in the so-called Evented Web. For this to happen, agent platforms need to seamlessly integrate external sources such as web services. As a solution, this paper introduces an event-based architecture for agent systems. This architecture has been designed in accordance with the new tendencies in web programming and with a Linked Data approach. The use of Linked Data and a specific vocabulary for events allows a smarter and more complex use of events. Two use cases have been implemented to illustrate the validity and usefulness of the architecture.

Authors: Habes Mohamed Raouf , Belleili-Souici Habiba , Vercouter Laurent
Published: February 2017

In the automated many-to-many negotiation model for leasing resource contract under Cloud computing environment, the main concern will be over finding a good approximation approach to this type of negotiation problem, since an optimal solution to that problem would be intractable due to the inherent complexity of the leasing resource negotiation along with the Cloud’s specifications. In order to get that good approximation, decentralized negotiation, leveled commitment contracts as well as lightweight agent strategies had been proposed, resulting to a fast and well-approximate negotiation decisions. To this end, we had conceived a “composite-greedy” algorithm for the seller’s strategy to address a variant of WDP which is the seller’s main problem under such settings. The composite greedy seller strategy will be a two-step strategy: the first one applies a classification according to the offers’ revenue and the second one according to the offers’ densities, and thereafter the seller will pick the one that maximizes the most his expected utility. Experimental results show the effectiveness of our approach compared to some related ones over different performance measures.

The objective of this study is to develop and test the feasibility of applying a machine learning method for geometry calibration of angles in micro-tomography systems. Increasing importance of micro-tomography systems are manifested with escalating applications in various scenarios including but not limited to oral and maxillofacial surgery, vascular and intervention radiology, among other specific applications for purposes of diagnosis and treatments planning. There is possibility, however, actual pathology is confused by artifact of tissue structures after volume reconstruction as a result of CT construction errors. A Kernel Ridge Regression algorithm for micro-tomography geometry estimation and its corresponding phantom is developed and tested in this study. Several projection images of a rotating Random Phantom of some steel ball bearings in an unknown geometry with gantry angle information were utilized to calibrate both in-plane and out-plane rotation of the detector. The described method can also be expanded to calibrate other parameters of CT construction effortlessly. Using computer simulation, the study results validated that geometry parameters of micro-tomography system were accurately calibrated.

Sepsis is defined as a syndrome of inflammatory response, motivated by an aggressive agent, associated with systemic infection, the early approach of the infectious agent, both in the direction of diagnosis and in the control of infectious focus, are fundamental for the good evolution of the patient. This pathology has been considered a global health problem, affecting a large number of people and causing high rates of morbidity and mortality.

OBJECTIVE: The study aimed to investigate how nurses contribute in an educational way in the prevention of complications caused by sepsis in an intensive care unit.

METHOD: The research was carried out through an electronic search of scientific papers published in the databases LILACS, SCIELO and PUBMED, portal of the virtual library in health. Other materials were located in scientific journals available on university websites and articles related to the subject. The initial evaluation of the material occurred through the reading of the abstracts, in order to select those that met the objectives of the study, with this, 37 articles were selected. In carrying out the research it was possible to verify that the recognition of sepsis by nursing professionals is mainly identified through the changes in the signs and symptoms that are observed through the provision of care to these critical patients.

RESULTS: It has been shown that even with all the advances in the production of knowledge about the pathophysiology and the treatment of sepsis, it is still possible to find several difficulties for the proper handling in the diagnosis and in the ideal treatment for each particular case.

CONCLUSION: The professional nurse should always be updating and seeking new knowledge for a fast, safe and effective action, in conjunction with the entire health team to promote quality and resolutive care for the patient, especially those affected by sepsis.

Objective: This study aimed to know the performance of nurses in radiotherapy services.

Methods and Results: It is a cross-sectional, descriptive and exploratory study with a quantitative approach, developed from June to July 2015. The study sample was composed of eight nurses. The data were collected through a structured questionnaire, analyzed through descriptive statistics. It was verified that nurses are not only restricted to care, buy they work in the supervision of the nursing team, monitor the work process, elaborate the action plan, select materials and equipment, schedule the consultations. In addition, it was possible to observe the importance of the nursing consultation for the individualization of the care and effectiveness of the treatment for the patient.

Conclusion: It is observed that for a good progress of the radiotherapy service, there is a need for a trained nursing team with conditions to deal with the complexity and requirements that this modality of treatment demands.

The natural aging process accelerate the appearance and the installation of diseases and symptoms characteristic of the age in which the physical and cognitive aspects are compromised progressively. Increasing the necessity of specialized cares and intensive accompaniment. This study aimed to evaluate through the Nursing Activities Score appliance, the nursing team’s working load, destined to elderly people assisted at intensive unit care and subsidize the personal sizing according to what advocate the legislation. It is about a descriptive and documental study of quantitative approach. It was used as data basis 50 patient records of elderly users admitted at a public intensive unit care from João Pessoa, Paraíba, Brazil. It was determined that 56% (28) of the elderly in his first hospitalization day at the Intensive Unit Care, required a nursing high working load while 44% (42) a nursing low working load.

Through the sum of the Nursing Activities Score average score, we can achieve the total of hours at the nursing assistance necessaries to the elderly patient care during the hospitalization. The average scores obtained by the total score, corresponded to 59.2 ± 7.8, transforming in hours according to the conducted calculus, correspond to 14.47 hours of nursing assistance turned to the elderly people. It is waited that the results can contribute to quantify the expended assistance time and also evidence the real necessity of the people to ensure safe and quality assistance practices to the elderly people.

The current study has the objective to identify main work accidents that occurs with nursing workers. This is an integrative literature review that enabled to include scientific articles indexed in the databases of Virtual Library in Health (BVS). Searches were made from october to november 2016, using the descriptors: “work accidents”, “nursing professionals”, separated between themselves by the boolean operator AND.

The following criteria were adopted: fully available articles, in portuguese language, published in the last five years. Articles that presented some duplicity and didn’t meet the proposed study objectives were excluded.

After searches, ten scientific productions about the subject were selected. Results indicate the occurrence of accidents between nursing professionals and the main factors were related with sharp object handling, non-utilization of IPEs, excessive workload and needle resurfacing.

It is concluded that strategies are required to minimize these occurrences, as the adoption of standard precautionary measures, the adequacy of staff numbers and better work conditions to this professional category. Besides that, the need of new researches about this subject are emphasized.
How to COAAD Images. I. Optimal Source Detection and Photometry of Point Sources Using Ensembles of Images
Authors: Zackay Barak , Ofek Eran O.
Published: February 2017

Stacks of digital astronomical images are combined in order to increase image depth. The variable seeing conditions, sky background, and transparency of ground-based observations make the coaddition process nontrivial. We present image coaddition methods that maximize the signal-to-noise ratio (S/N) and  optimized for source detection and flux measurement. We show that for these purposes, the best way to combine images is to apply a matched filter to each image using its own point-spread function (PSF) and only then to sum the images with the appropriate weights. Methods that either match the filter after coaddition or perform PSF homogenization prior to coaddition will result in loss of sensitivity. We argue that our method provides an increase of between a few and 25% in the survey speed of deep ground-based imaging surveys compared with weighted coaddition techniques. We demonstrate this claim using simulated data as well as data from the Palomar Transient Factory data release 2. We present a variant of this coaddition method, which is optimal for PSF or aperture photometry. We also provide an analytic formula for calculating the S/N for PSF photometry on single or multiple observations. In the next paper in this series, we present a method for image coaddition in the limit of background-dominated noise, which is optimal for any statistical test or measurement on the constant-in-time image (e.g., source detection, shape or flux measurement, or star–galaxy separation), making the original data redundant. We provide an implementation of these algorithms in MATLAB.

We present 5–20 μm spectral maps of the reflection nebula NGC 2023 obtained with the Infrared Spectrograph SL and SH modes on board the Spitzer Space Telescope, which reveal emission from polycyclic aromatic hydrocarbons (PAHs), C60, and H2 superposed on a dust continuum. We show that several PAH emission bands correlate with each other and exhibit distinct spatial distributions that reveal a spatial sequence with distance from the illuminating star. We explore the distinct morphology of the 6.2, 7.7, and 8.6 μm PAH bands and find that at least two spatially distinct components contribute to the 7–9 μm PAH emission in NGC 2023. We report that the PAH features behave independently of the underlying plateaus. We present spectra of compact, oval PAHs ranging in size from C66 to C210, determined computationally using density functional theory, and we investigate trends in the band positions and relative intensities as a function of PAH size, charge, and geometry. Based on the NASA Ames PAH database, we discuss the 7–9 μm components in terms of band assignments and relative intensities. We assign the plateau emission to very small grains with possible contributions from PAH clusters and identify components in the 7–9 μm emission that likely originate in these structures. Based on the assignments and the observed spatial sequence, we discuss the photochemical evolution of the interstellar PAH family as the PAHs are more and more exposed to the radiation field of the central star in the evaporative flows associated with the Photo-Dissociation Regions in NGC 2023.

Ages and masses of young stars are often estimated by comparing their luminosities and effective temperatures to pre-main-sequence stellar evolution tracks, but magnetic fields and starspots complicate both the observations and evolution. To understand their influence, we study the heavily spotted weak-lined T-Tauri star LkCa 4 by searching for spectral signatures of radiation originating from the starspot or starspot groups. We introduce a new methodology for constraining both the starspot filling factor and the spot temperature by fitting two-temperature stellar atmosphere models constructed from Phoenix synthetic spectra to a high-resolution near-IR IGRINS spectrum. Clearly discernable spectral features arise from both a hot photospheric component

 ∼ 4100 K and a cool component

 ∼ 2700–3000 K, which covers ∼80% of the visible surface. This mix of hot and cool emission is supported by analyses of the spectral energy distribution, rotational modulation of colors and of TiO band strengths, and features in low-resolution optical/near-IR spectroscopy. Although the revised effective temperature and luminosity make LkCa 4 appear to be much younger and of much lower mass than previous estimates from unspotted stellar evolution models, appropriate estimates will require the production and adoption of spotted evolutionary models. Biases from starspots likely afflict most fully convective young stars and contribute to uncertainties in ages and age spreads of open clusters. In some spectral regions, starspots act as a featureless “veiling” continuum owing to high rotational broadening and heavy line blanketing in cool star spectra. Some evidence is also found for an anticorrelation between the velocities of the warm and cool components.
