О мгновенном разрушении решений эволюционных задач на полупрямой
Authors: Korpusov Maxim Olegovich
Published: September 2018

В работе рассмотрены некоторые начально-краевые задачи
на полупрямой для "1+1"-мерных уравнений соболевского типа
с однородными граничными условиями на начале полупрямой. Показано, что
слабые решения этих задач отсутствуют даже локально во времени. Кроме того,
рассмотрены задачи на отрезке с теми же граничными условиями на одном из
концов отрезка $[0,L]$. Доказана локальная во времени однозначная разрешимость
в классическом смысле рассматриваемых задач и получены достаточные условия разрушения их решений за конечное время. Из полученных оценок сверху на времена разрушения классических
решений соответствующих задач показано, что время разрушения стремится к нулю при $L\to+\infty$. Таким образом,
классическое решение на прямой тоже отсутствует даже локально, и при этом предъявлен
алгоритм для последующей численной диагностики мгновенного разрушения на полупрямой.

Продолжение функций из неизотропных пространств Никольского-Бесова и приближение их производных
Authors: Kudryavtsev Sergey Nikolaevich
Published: September 2018

В статье рассмотрены неизотропные пространства Никольского и Бесова с нормами, в определении которых вместо модулей непрерывности известных порядков производных функций по координатным направлениям используются "$L_p$-усредненные" модули непрерывности функций соответствующих порядков по тем же направлениям. Для таких пространств функций, заданных в областях определенного типа, построены непрерывные линейные отображения их в обычные неизотропные пространства Никольского и Бесова в $ \mathbb{R}^d$, являющиеся операторами продолжения функций, что влечет совпадение тех и других пространств в упомянутых областях. В работе также найдена слабая асимптотика аппроксимационных характеристик, относящихся к задаче восстановления производной по значениям функций в заданном числе точек, задаче С. Б. Стечкина для оператора дифференцирования и задаче описания асимптотики поперечников для неизотропных классов Никольского и Бесова в этих областях.

О классификации многообразий, порожденных сплетениями групп
Authors: Mikaelian Vahagn H.
Published: September 2018

Мы предлагаем классификацию всех случаев, когда для нильпотентной группы конечной экспоненты $A$ и для абелевой группы $B$ многообразие $\operatorname{var}(A \mathbin{\mathrm{Wr}} B)$, порожденное их сплетением $A \mathbin{\mathrm{Wr}} B$, равно произведению $\operatorname{var}(A)\operatorname{var}(B)$ многообразий $\operatorname{var}(A)$ и $\operatorname{var}(B)$, порожденных группами $A$ и $B$. Это обобщает ряд известных в литературе результатов, рассматривающих подобную проблему применительно к более ограниченным типам групп. Представленная классификация также является продолжением наших предыдущих работ о многообразиях, порожденных сплетениями абелевых групп и сплетениями конечных групп.

Относительные $K$-группы Милнора и дифференциальные формы расщепимых нильпотентных расширений
Authors: Gorchinskiy Sergey Olegovich , Tyurin Dimitrii Nikolaevich
Published: September 2018

Пусть $R$ - коммутативное кольцо, а $I\subset R$ - нильпотентный идеал, для которого фактор-кольцо $R/I$ отщепляется от $R$. Пусть $N\geqslant 1$ - такое натуральное число, что $I^N=0$. В статье строится канонический изоморфизм между относительной $K$-группой Милнора $K^{M}_{n+1}(R,I)$ и фактором относительного модуля дифференциальных форм $\Omega^n_{R,I}/d\Omega^{n-1}_{R,I}$ в предположении, что число $N!$ обратимо в $R$ и что кольцо $R$ слабо $5$-стабильно. Последнее означает, что любые четыре элемента кольца $R$ могут быть сдвинуты на обратимый элемент так, чтобы они стали обратимыми.

Диагональные комплексы
Authors: Gordon Joseph Aleksandrovich , Panina Gaiane Yur'evna
Published: September 2018

Известно, что частично упорядоченное множество наборов непересекающихся диагоналей в $n$-угольнике изоморфно решетке граней некоторого выпуклого многогранника, называемого ассоциэдр. Заменим $n$-угольник (на который следует смотреть как на диск с $n$ отмеченными точками на крае) на произвольную ориентированную поверхность с набором занумерованных отмеченных точек ("вершин"). Дав подходящие определения, мы строим клеточный комплекс $\mathcal{D}$ (обобщение ассоциэдра) и его барицентрическое подразбиение $\mathcal{BD}$. Если поверхность замкнута, то комплекс $\mathcal{D}$ (так же как и $\mathcal{BD}$) гомотопически эквивалентен пространству метрических ленточных графов $RG_{g,n}^{\mathrm{met}}$, или, что то же самое, декорированному пространству модулей $\widetilde{\mathcal{M}}_{g,n}$. Для поверхности с краем мы показали, что 1) стягивание ребра не меняет гомотопического типа комплекса; 2) стягивание компоненты края в отмеченную точку приводит к забывающему отображению между двумя диагональными комплексами, которое гомотопически эквивалентно тавтологическому расслоению Концевича со слоем "окружность". Таким образом, мы получаем естественную симплициальную модель тавтологического расслоения. В качестве приложения мы вычислили пси-класс, т. е. первый класс Черна в комбинаторных терминах. Этот результат получен применением локальной комбинаторной формулы. 3) Аналогично, стягивание нескольких компонент края поверхности соответствует сумме Уитни тавтологических расслоений.

Local Voices on forced mergers in small rural Australian communities:The case of the Guyra Shire Council
Authors: Wallace Andrea , Dollery Brian
Published: September 2018

When an Australian state or territory government launches a program of forced municipal mergers, it typically attracts much less attention in metropolitan areas compared with regional, rural and remote locations where the local council is often “government of last resort”. In these latter areas the socio-economic effects of compulsory council consolidation can be severe. This paper explores the perceived impact of the forced amalgamation of Guyra Shire Council with the much larger neighbouring Armidale Dumaresq Council under the recent New South Wales (NSW) Government’s Fit for the Future structural reform program by anticipated by Guyra residents who participated in a focus group.
Constraining the aerosol influence on cloud liquid water path

Published: September 2018

Abstract. The impact of aerosols on cloud properties is one of the largest uncertainties in the anthropogenic radiative forcing of the climate. In recent years, significant progress has been made in constraining this forcing using observations, but uncertainty still remains, particularly in the adjustments of cloud properties to aerosol perturbations. Cloud liquid water path (LWP) is the leading control on liquid-cloud albedo, making it important to observationally constrain the aerosol impact LWP. Previous modelling and observational studies have shown that multiple processes play a role in determining the LWP response to aerosol perturbations, but that the aerosol effect can be difficult to isolate. Following previous studies using mediating variables, this work investigates use of the relationship between cloud droplet number concentration (Nd) and LWP for constraining the role of aerosols. Using joint probability histograms to account for the non-linear relationship, this work finds a relationship that is broadly consistent with previous studies. There is significant geographical variation in the relationship, partly due to role of meteorological factors (particularly relative humidity) in the relationship. However, the Nd-LWP relationship is negative in the majority of regions, suggesting that aerosol induced LWP reductions could offset a significant fraction of the radiative forcing from aerosol-cloud interactions (RFaci). However, variations in the Nd-LWP relationship in response to volcanic and shipping aerosol perturbations indicate that the Nd-LWP relationship overestimates the Nd impact on LWP. As such, the estimate of LWP changes due to aerosol in this work provides an upper bound to the radiative forcing from aerosol-induced changes in the LWP.
Preflight calibration of the Chinese Environmental Trace Gases Monitoring Instrument (EMI)
Authors: Zhao Min Jie , Si Fu Qi , Zhou Hai Jin , Wang Shi Mei , Jiang Yu , Liu Wen Qing
Published: September 2018

Abstract. An environmental trace gases monitoring instrument (EMI) is a nadir-viewing
wide-field imaging spectrometer, which aims to quantify the global
distribution of tropospheric and stratospheric trace gases, and is planned to
be launched on 9 May 2018. The selected wavelength bands for EMI are
ultraviolet channels: UV1 (240–315 nm), UV2 (311–403 nm) and visible
channels: VIS1 (401–550 nm), and VIS2 (545–710 nm). The spectral resolution
is 0.3–0.5 nm, and the swath is approximately 114∘ wide to achieve
a one-day global coverage. The preflight calibration of the EMI is discussed
in this paper. A tunable laser and rotating platform are adopted for an EMI
wavelength calibration of the entire field of view. The accuracy of the
wavelength calibration is less than 0.05 nm. In addition, the solar
calibration mode shows the same results compared with Earth observation mode.
A thermal vacuum test is performed to investigate the influence of in-orbit
thermal vacuum conditions on the EMI, and EMI spectral response changes with
pressure, optical bench temperature, and charge-coupled device (CCD) detector
temperature are obtained. For a radiometric calibration of UV1, a diffuser
plate with a 1000 W xenon lamp, which produces sufficient UV output, is
selected. An integrating sphere system with tungsten halogen lamp is selected
for the UV2, VIS1, and VIS2. The accuracies of radiance calibration are
4.53 % (UV1), 4.52 % (UV2), 4.31 % (VIS1), and 4.30 % (VIS2). The
goniometry correction factor and irradiance response coefficient of the EMI
are also calibrated on the ground for an in-orbit calibration of the solar. A
signal-to-noise ratio (SNR) model of the EMI is introduced, and the EMI
in-orbit SNR is estimated using the SNR and MODTRAN radiance
models.

Published: September 2018

Abstract. A set of seasonal drought forecast models was assessed and verified for the
Jaguaribe River in semiarid northeastern Brazil. Meteorological seasonal
forecasts were provided by the operational forecasting system used at FUNCEME
(Ceará's research foundation for meteorology) and by the European Centre
for Medium-Range Weather Forecasts (ECMWF). Three downscaling approaches
(empirical quantile mapping, extended downscaling and weather pattern
classification) were tested and combined with the models in hindcast mode for
the period 1981 to 2014. The forecast issue time was January and the forecast
period was January to June. Hydrological drought indices were obtained by
fitting a multivariate linear regression to observations. In short, it was
possible to obtain forecasts for (a) monthly precipitation,
(b) meteorological drought indices, and (c) hydrological drought indices. The skill of the forecasting systems was evaluated with regard to root mean
square error (RMSE), the Brier skill score (BSS) and the relative operating
characteristic skill score (ROCSS). The tested forecasting products showed
similar performance in the analyzed metrics. Forecasts of monthly
precipitation had little or no skill considering RMSE and mostly no skill
with BSS. A similar picture was seen when forecasting meteorological drought
indices: low skill regarding RMSE and BSS and significant skill when
discriminating hit rate and false alarm rate given by the ROCSS (forecasting
drought events of, e.g., SPEI1 showed a ROCSS of around 0.5). Regarding
the temporal variation of the forecast skill of the meteorological indices,
it was greatest for April, when compared to the remaining months of the rainy
season, while the skill of reservoir volume forecasts decreased with lead
time. This work showed that a multi-model ensemble can forecast drought events of
timescales relevant to water managers in northeastern Brazil with skill. But
no or little skill could be found in the forecasts of monthly precipitation
or drought indices of lower scales, like SPI1. Both this work and those
here revisited showed that major steps forward are needed in forecasting the
rainy season in northeastern Brazil.

MULTIVARIATE REGRESSION APPLIED TO THE PERFORMANCE OTIMIZATION OF A COUNTERCURRENT ULTRACENTRIFUGE - A PRELIMINARY STUDY
Authors: Migliavacca E.
Published: September 2018

In this work, the least-squares methodology with covariance matrix is applied to determine a data curve fitting in order to obtain a performance function for the separative power U of an ultracentrifuge as a function of variables that are experimentally controlled. The experimental data refer to 173 experiments on the ultracentrifugation process for uranium isotope separation. The experimental uncertainties related to the independent variables measurements are considered in the calculation of the experimental separative power values, determining an experimental data input covariance matrix. The process control variables, which significantly influence the U values, are chosen in order to give information on the ultracentrifuge behaviour when submitted to several levels of feed flow F and cut . After the model goodness-of-fit validation, a residual analysis is carried out to verify the assumed basis concerning its randomness and independence and mainly the existence of residual heteroscedasticity with any regression model variable. The response curves are made relating the separative power with the control variables F and , to compare the fitted model with the experimental data and finally to calculate their optimized values.
Fair Value Accounting Practices and Efficiency of Banks: A Theoretical Perspective
Authors: Jayasekara S G Sisira Dharmasri , Perera K L Wasantha , Ajward A Roshan
Published: September 2018

This conceptual paper discusses the impact of fair value accounting practices on performance of commercial banks in relation to  the  established banking theories i.e. Credit creation, fractional reserve and financial intermediation theory. These theories are discussed in view of historical cost accounting principles and fair valued accounting principles considering the performance in terms of efficiency during different stages of economic conditions. The analysis shows that fair value accounting practices in banks create reserves in economic booms improving efficiency and deteriorate created reserves in economic downturns causing financial crises.  Enhanced financial performance in terms of unrealized gains improves the overall efficiency of banks in view of the intermediation approach of the financial intermediation theory. Therefore, it can be interpreted that external factors such as accounting, infrastructure, and technology can influence efficiency of the financial intermediation process. This is the first study to discuss the implications of fair value accounting on banking theory in view of performance of banks and stability of financial system.
Decoding the Visual Rhetoric: Memory and Trauma in Lynda Barry’s One! Hundred! Demons!
Authors: Bhattacharjee Partha , Tripathi Priyanka
Published: September 2018

Memory is an important tool in Lynda Barry’s One! Hundred! Demons! (2002) as she reconnoitres in non-linear fragments the personal trauma she faced while she was growing up. Layered into nineteen disjointed chapters, Barry’s graphic narrative is an amalgamation of images, collages and photographs, often following the pattern of a scrapbook style that justifies not only the events drawn in her narrative but also the motive of visual rhetoric in comics where visual images communicate and concretize meaning. Initially published as web comics (slate.com), each chapter consists of hand-painted vignettes of multifarious themes which are directly or indirectly linked to Barry’s life, covering from her childhood to adulthood. In the backdrop of these tools, techniques of visual rhetoric the objective of this paper is to investigate the form of the graphic narrative, the visual language employed in order to explore the traumatised childhood, memory and truth-telling in comics.
Training Transfer: Does Training Design Preserve Training Memory?
Authors: Alshaali Saeed Khalifa , Hamid Kamal Ab , Al-Ansi Ali Ali
Published: September 2018

Billions of dollars are lost by low application of ineffective training. Fast declination of training memory may contribute this loss. The present study uses theoretical examinations via a conceptual model to examine the relationship between training memory and transfer behaviour. Training design, training retention (training memory), and training transfer are the study variables. The study population, is the federal ministries in the United Arab Emirates (UAE), was assessed via random sampling. Data were collected by a cross-sectional approach via questionnaires. Back-translation (English to Arabic), a pre-test, and a pilot test were applied to ensure that any modifications of the questionnaire items were precise and effective. The study was analysed via PLS-SEM. Based on the results, all of the study’s hypotheses were accepted, and significant relationships were revealed between the study variables. Training design is highly correlated with training retention, i.e., a premium training design will lead to a high preservation of the knowledge and skills gained from the training programme. Due to the low correlation between training retention and training transfer, the training retention was considered a secondary contributor of applying training to the work environment. If mangers and practitioners tend to achieve successful training transfer, their efforts should concentrate on adopting modern training design techniques, which could sufficiently maintain the training memory and increase training transfer.
New concepts of non-adherence among patients undergoing hemodialysis - a qualitative study exploring specific types of adherence/nonadherence
Authors: Tamaura Yuki , Kawasaki Yui , Akamatsu Rie
Published: September 2018

Rationale, aims and objectives: To determine more effective intervention, this qualitative study explores the specific behaviors of adult patients undergoing hemodialysis with regard to dietary and fluid restrictions. Additionally, to understand their characteristics, identified behaviors were categorized as being either intentional or unintentional.Methods: This study employed a descriptive exploratory design comprising individual semi-structured interviews. It was conducted from July to September 2014 in one private dialysis facility treating 73 outpatients in Tokyo, Japan. Forty-three patients receiving hemodialysis treatment consented to participate. Behaviors identified in the interviews were categorized by considering “the motivation behind them (intentional/unintentional)” and their “adequacy (if the behavior seems to lead adherence or not).”Results: This study identified 32 categories of “intentional behaviors” and 14 categories of “unintentional behaviors”. Intentional behaviors included general behaviors of “making adjustments in diet” and non-adherence behaviors of “taking halfway measures” and “abandonment”. Unintentional behaviors comprised general behaviors practiced after the initiation of HD therapy, in addition to non-adherence behaviors due to “habituation” and “dietary environments”.Conclusions: A total of 46 categories of specific behaviors regarding dietary and fluid restrictions in patients receiving HD were identified. Categories were then divided into two different types: intentional and unintentional. Though certain characteristics were similar to other adherence behaviors such as those toward medication, the current study also proposes some unique aspects of dietary behaviors with respect to diversity and habitual strength. Understanding the characteristics of different types of non-adherence behaviors, such as whether they are intentional or unintentional, could be a potentially important contribution to interventions.
Mapping similarities and differences to progress mutual understanding and dialogue: A comparison and contrast of evidence-based practice and person-centered healthcare
Authors: Marcum James
Published: September 2018

Evidence-based practice and person-centered healthcare are often seen as opposing approaches to clinical practice. And yet both offer advantages to providing quality healthcare. In this paper, both approaches to clinical practice are analyzed and mapped philosophically by comparing and contrasting their key foundational principles. The goal is to progress the dialogue between them in order to determine whether a common ground exists in which they might be integrated and how best to operationalize, both clinically and pedagogically, an integrated approach. To that end, key principles undergirding them are enumerated and then integrated by shifting the focus from evidence to the person - whether patient or clinician - for the delivery of quality healthcare. In this way, person-centered healthcare provides the optimal starting point for framing evidence-based practice. Next, operationalizing the integrated approach to clinical practice and medical education is addressed. Finally, the root of modern healthcare must be a person’s, whether patient’s or clinician’s, dignity. For the goal of healthcare is to relieve suffering associated with illness, whether that involves curing a disease or not and not adding to the suffering associated with illness.
Developing a new questionnaire to measure nurse caring behaviours: a mixed method study
Authors: Ambrosi Elisa , Canzan Federica , Zenere Alessandra , Grassi Mario , Tardivo Stefano , Mortari Luigina , Saiani Luisa , Zanolin Elisabetta
Published: September 2018

Rationale, aims and objective: Measuring nurse caring may provide empirical evidence to assist clinicians and administrators in making decisions. The aim of the present study was to develop a new scale, called the CARE-Italy, grounded in the Italian culture, for measuring nurses’ caring behaviours.Methods: A mixed method approach was applied in developing the instrument. The item generation and scale development were performed through a qualitative phenomenological approach and a focus group with a panel of experts. The provisional instrument was then administered to a convenience sample of 439 nurses and then questionnaire scaling and association analysis were performed. A dual scaling analysis of successive categories was performed to identify preferences on the rating scale. An item selection based on item-scale correlations and item weights was performed. Subjects’ mean scores were computed and standardized in a 100-point scale.Results: The 20 caring behaviours perceived by nurses to be the most important ones constitute the final version of the CARE-Italy questionnaire. They concern patients’ surveillance, professional relationships with patients, satisfying patients’ and family members’ practical and psychological needs, team consultation and nurses’ emotions.Conclusions:  A relational and paternalistic caring approach by Italian nurses seems to be suggested. The next step of the research project will be the validation process of the CARE-Italy questionnaire with a Likert scale measuring the occurrence of the 20 caring behaviours in daily practice.
An integrated model of care for young people with liver disease and transplant
Authors: Hames Anna , Simpson Anna , Matcham Faith , Day Jemma , Joshi Deepak , Samyn Marianne
Published: September 2018

Rationale, aims and objectives: Young people (YP) with chronic illness have increased risk of mental health problems.   This   paper   evaluates   the   feasibility,   acceptability   and effectiveness of incorporating routine electronic mental health screening into the standard multidisciplinary healthcare of YP with chronic liver disease and liver transplant.Methods: One hundred and eighty-seven YP (mean age 18 years, 53% female) attending routine appointments in a tertiary service in the UK completed mental health screening prior to their clinic appointment. These standardized measures (the 9-item Patient Health Questionnaire [PHQ9] and the 7-item Generalised Anxiety questionnaire [GAD7]) were completed using an informatics system that facilitates routine collection of patient-reported outcomes, with real-time feedback to guide clinical care. Responses are immediately uploaded to medical notes and evaluated by the clinical team. Fifty-three YP completed an additional feasibility measure. YP screening positive were assessed by the clinical team, with appropriate support offered. Level of clinician agreement with screening programme was ascertained by the team’s clinical psychologist.Results: YP reported that completing the electronic screening was acceptable, a positive experience and that routine mental health screening in this manner would not affect the way they felt about coming to clinic. Clinician judgement corroborated 31 of the 33 YP who screened as positive for anxiety/depression. Screening did not effectively identify all YP warranting psychosocial input.Conclusions: Screening using electronic measures, with responses uploaded in real-time to medical notes for consultant review, can facilitate the rapid identification of mental health problems in YP with physical health problems, in an acceptable and time/cost-effective way. This should be combined with the support of embedded mental health practitioners within physical healthcare environments.
The subjective experience of Parkinson’s disease: A qualitative study in 60 people with mild to moderate Parkinson’s in 11 European countries
Authors: Merritt Rowena K , Hotham Sarah , Graham Lizzie , Schrag Anette
Published: September 2018

Objective: To describe the experience of being diagnosed and living with mild to moderate Parkinson’s disease (PD).Method: Semi-structured in-depth interviews with people with Parkinson’s (PwP) in 11 European countries.Results: Interviews with 60 PwP (52% male) with a mean age of 63 (SD 8.1) years and a disease duration of 9.6 (SD 6.9) years were analysed. PwP often delayed help-seeking due to lack of awareness of symptoms and there was sometimes a delay in specialist referral. The diagnosis typically came as a “shock”, making PwP unable to absorb all the information, but having a diagnosis for the symptoms was sometimes described as a “relief”. Prompt referral to a specialist, a clear and sensitively communicated diagnosis with reassurance about prognosis and a follow-up appointment with a PD nurse or other healthcare professionals a short interval after diagnosis were all positively viewed. Many reported worries and negative experiences with medications and wished for more time and information before initiating these. Reactions from family, friends and work colleagues when communicating the diagnosis were typically positive. During ongoing care, longer appointments with specialists and provision of information from healthcare professionals, patient organisations and self-help groups were considered important to many PwPs and helped them feel as if they could “take control” and manage their disease more effectively.Conclusions: Taking into account these findings has the potential to improve the experiences of PwP through improved communication, tailoring of appointments and information provision including self-help approaches.
Influência do congelamento na obtenção de blocos precursores de carvões adsorventes elaborados com bananas
Authors: Souza Pércia Graczyk , Queiroz Tadeu Miranda de , Yamaguchi Thaynara Melo
Published: September 2018

O emprego de rejeitos da bananicultura na elaboração de materiais adsorventes, tem se apresentado favorável devido à diminuição dos custos de produção, agregação de valor à matéria-prima, e aos bons resultados que vêm sendo registrados por diversos estudos de caso.O objetivo deste trabalho foi caracterizar carvões adsorventes elaborados a partir de bananas verdes e maduras, empregando-se cascas, polpa e os frutos integrais, considerando duas metodologias que envolveram ou não, o congelamento como uma das etapas de obtenção dos blocos precursores dos carvões adsorventes. Foram avaliadas as propriedades físico-químicas dos carvões, sendo que não foram obtidas diferenças significativas nas variáveis umidade e rendimento em massa, no que se refere ao emprego do congelamento como uma das etapas de confecção dos blocos. Os carvões feitos a partir das cascas de bananas verdes e maduras apresentaram menor teor de cinzas quando não se empregou o congelamento. Os blocos feitos com cascas de banana verde e com a polpa de banana madura apresentaram maior densidade aparente quando se utilizou o congelamento. Apenas a densidade relativa dos blocos feitos com polpa de bananas maduras apresentou diferenças, em que o congelamento influenciou na redução do valor deste parâmetro. A porosidade total dos adsorventes foi maior quando o congelamento não foi utilizado na elaboração da maioria dos tipos de blocos. Desta forma, o emprego do congelamento se mostrou importante para promover a aglutinação da massa feita com bananas, conferindo assim, o formato e a compactação dos blocos até o final do processamento, entretanto, esta etapa não exerceu relevância frente às características físico-químicas avaliadas.

Published: September 2018

Entender como as políticas públicas são fundamentadas e seu impacto na sociedade é um desafio para muitas áreas de estudos no Brasil, torna-se uma tarefa árdua quando essas políticas são voltadas para determinados grupos, como as comunidades quilombolas. Diante disso, ainda existem algumas lacunas entre o que é realizado e o que o cidadão realmente percebe em sua efetividade. Nesse aspecto, o estudo objetivou identificar a percepção das políticas públicas nas comunidades quilombolas do território “Vão Grande” em Barra do Bugres-MT. O percurso metodológico utilizado foi baseado na pesquisa quali-quantitativa, com a escolha do sujeitos feita por meio da técnica de amostragem Snowball (bola de neve) e os dados coletados a partir da aplicação de questionário semiestruturado, tabulado, transcrito e analisado com base no recorte teórico que orienta a presente pesquisa. Com base no resultado da pesquisa é possível concluir que diversas políticas públicas de infraestruturas são implantadas nas comunidades, como, por exemplo, o fornecimento de energia elétrica, água, escolas. Contudo, os moradores declararam não participar de nenhuma política que incentive a vida no meio rural, tornando as condições de permanência no campo mais difíceis, haja vista que a maioria dos entrevistados sente-se esquecido/abandonado em razão das dificuldades com transporte, estrada, saúde e geração de renda.

Published: September 2018

No estado de Mato Grosso as divisões territoriais não foram constituídas a partir de um planejamento ambiental e espacial, desconsiderando as diferenças regionais e as peculiaridades das diversas microrregiões. A paisagem foi sendo alterada no decorrer dos anos, na medida em que a atividade econômica demandava a expansão de área para o seu desenvolvimento. Diante do exposto objetivou-se realizar a análise espaço-temporal da estrutura da paisagem do município de Porto Esperidião-MT, na perspectiva da geração de informações que contribuam no planejamento e na gestão ambiental municipal. O trabalho foi executado através das seguintes etapas: levantamentos de bases cartográficas nos projetos Radambrasil (1982) e Probio (1997); registro de imagens, recorte, segmentação, classificação digital de imagens orbitais, quantificação dos dados e elaboração dos mapas temáticos. Os resultados mostram alterações em todas as classes de vegetação durante os últimos 29 anos (1982-2011), ocorrendo diminuição de 54,77% da vegetação nativa e aumento de 54,22% de uso da terra, principalmente vinculado as pastagens para pecuária bovina. Relativo à estrutura da paisagem municipal constatou-se no período analisado que o uso antrópico contribuiu para a fragmentação da vegetação natural, sendo a matriz em 1982 constituída pela vegetação e em 2002 e 2011 pela pastagem. Concluiu-se que no período investigado entre os anos de 1982 e 2011 a vegetação natural de Porto Esperidião foi suprimida principalmente em função do desenvolvimento da atividade agropecuária, acarretando diminuição na vegetação dos biomas presentes e aumento no número de fragmentos, consequentemente reduzindo a biodiversidade de fauna e flora e impactando a conservação ambiental.
La Identidad Digital del alumnado universitario: Estudio descriptivo en la facultad de Educación de la Universidad de Murcia.
Authors: Saorín Sánchez Francisco Luis , Gutiérrez Porlán Isabel
Published: September 2018

Este artículo aborda el fenómeno de la Identidad Digital y cómo éste es percibido por los estudiantes universitarios. La investigación realizada ha sido un estudio descriptivo contextualizado dentro de la metodología cuantitativa, con una muestra participante compuesta por 69 estudiantes pertenecientes todos ellos a la Facultad de Educación de la Universidad de Murcia.Para conseguir nuestros objetivos, desarrollamos nuestro propio cuestionario atendiendo a los trabajos de Castañeda y Camacho (2012), Pérez (2012) y Gamero (2009). El cuestionario fue validado mediante un Juicio de expertos y se aplicó de forma telemática. Entre los resultados más destacados encontramos que los estudiantes tienden a interactuar en Internet menos de lo esperado. También hemos encontrado que tener bloqueados contactos es una actitud ligada al desarrollo de su interacción social y que los universitarios no necesitan conocer a un contacto en la vida real para establecer una conexión emocional con ellos.

Authors: Padilla-Hernández Angelina Lorelí , Gámiz Sánchez Vanesa M.ª , Romero López M.ª Asunción
Published: September 2018

La competencia digital docente (CDD) puede comprenderse como una competencia en evolución a lo largo de la trayectoria profesional del profesorado. Este es el tema de investigación de una tesis doctoral en curso, cuyo objetivo general es caracterizar la adquisición y el desarrollo en la práctica de la competencia digital de docentes universitarios para reconocer su influencia en su evolución profesional. En este artículo se presentan las categorías identificadas para el diseño de un guion de entrevista en profundidad acerca de la evolución de dicha competencia. Se realizó la revisión de literatura especializada que incluyó el análisis descriptivo de dos modelos sobre la CDD del profesorado universitario y de los instrumentos de seis estudios recientes del ámbito iberoamericano. La síntesis se organizó en tres apartados: las líneas específicas de la CDD en la docencia universitaria, áreas de la competencia digital relacionadas con el desempeño de los docentes, y aspectos para comprender la evolución de la CDD. Como resultado se desarrolló el listado de dimensiones, categorías e indicadores sobre la evolución de la CDD en Educación Superior. Por último, se discute el alcance y las limitaciones de este listado, que se someterá a un estudio de obtención de evidencias de validez mediante el juicio de expertos.
Superpoderes contra el Dr. Discriminador. La mejora de la evaluación continua mediante la ludificación en el Máster en profesorado
Authors: Falcó-Boudet Jose Mª , Huertas Talón José Luis
Published: September 2018

La ludificación, esto es, motivar a las personas con las mecánicas de los juegos para que se involucren y participen con la finalidad de conseguir mejores resultados, también ha sido utilizada en contextos de Educación Superior. Con el objetivo de motivar la asistencia, la participación y la realización de las tareas de la evaluación continua en una asignatura del máster en profesorado, se implementó una dinámica de obtención de insignias ambientada en la consecución de superpoderes para luchar contra el Dr. Discriminador. La evaluación de los resultados se hizo mediante el análisis de las respuestas recogidas a través de un cuestionario y la comparación de los datos de asistencia y participación con los de cursos anteriores. Los resultados demuestran que, además de ser del agrado de los estudiantes, supuso un incentivo para realizar las actividades de evaluación continua.
El papel de las tecnologías digitales en la intervención educativa de niños con trastorno del espectro autista.

Este trabajo es el diseño de la investigación de una tesis doctoral cuyo objetivo general es elaborar un instrumento para la evaluación de aplicaciones móviles que promuevan la intervención educativa en niños con Trastorno del Espectro Autista (en adelante TEA). Dicho instrumento está pensado para evaluar aplicaciones móviles educativas que pueden resultar pertinentes en la intervención educativa con las personas con TEA. Actualmente nos situamos, según el modelo de investigación enfocado al diseño educativo (Educational Design Research, EDR), en la primera fase de la investigación (investigación preliminar). Hasta el momento, se ha definido el problema e iniciado, en primer lugar, la revisión de la literatura especializada y, en segundo lugar, el procedimiento de definición del método. Es por esto que, en este artículo, presentamos los contenidos clave de la fundamentación teórica en la que se está trabajando actualmente, el planteamiento de la investigación y una propuesta de definición del método.
Habilidades potenciadas con el e-Sport League of Legends: Diseño de caso único
Authors: Rodríguez González Christian , Del Moral Pérez Esther
Published: September 2018

Los e-Sports son videojuegos multijugador de gran éxito con un marcado carácter competitivo, que priman estrategias cooperativas y tomas de decisiones consensuadas, exigiendo un papel activo a los jugadores para ganar a sus rivales. La presente investigación analiza en qué medida el apoyo de un entrenador experto permite a los jugadores (N=10) de un e-Sport -como el League of Legends-, desarrollar sus habilidades lógico-matemáticas y entrenarlos para la toma de decisiones adecuadas a través del juego cooperativo. La metodología mixta adoptada permitió: a) contrastar el incremento de las habilidades de los sujetos del grupo experimental (GE) que recibió entrenamiento sobre el videojuego durante 8 sesiones y los del grupo de control (GC) que no, utilizando un test y postest; y, b) analizar las interacciones y decisiones primadas en el juego cooperativo. Los resultados muestran la mejora en las habilidades del GE frente al GC, subrayando el papel clave desempeñado por el entrenador.

Paleontology of the Bears Ears National Monument: history of exploration and designation of the monument
Authors: Uglesich Jessica , Gay Robert J , Stegner M. Allison , Huttenlocker Adam K , Irmis Randall B
Published: September 2018

Bears Ears National Monument (BENM) is a new, landscape-scale national monument jointly administered by the Bureau of Land Management and the Forest Service in southeastern Utah as part of the National Conservation Lands system. As initially designated, BENM encompasses 1.3 million acres of land with exceptionally fossiliferous rock units. These units comprise a semi-continuous depositional record from the Pennsylvanian Period through the middle of the Cretaceous Period. Additional Quaternary and Holocene deposits are known from unconsolidated river gravels and cave deposits. The fossil record from BENM provides unique insights into several important paleontological periods of time, including the Pennsylvanian-Permian transition from fully aquatic to more fully terrestrial tetrapods; the rise of the dinosaurs following the Triassic-Jurassic extinction; and the response of ecosystems in dry climates to sudden temperature increases at the end of the last ice age and across the Holocene. While the paleontological resources of BENM are extensive, they have historically been under-studied. Here we summarize prior paleontological work in BENM and review the data used to support paleontological resource protection in the 2016 BENM proclamation.
Balancing presynaptic release and endocytic membrane retrieval at hair cell ribbon synapses
Authors: Pangrsic Tina , Vogl Christian
Published: September 2018

The timely and reliable processing of auditory and vestibular information within the inner ear requires highly sophisticated sensory transduction pathways. On a cellular level, these demands are met by hair cells, which respond to sound waves – or alterations in body positioning – by releasing glutamate‐filled synaptic vesicles (SVs) from their presynaptic active zones with unprecedented speed and exquisite temporal fidelity, thereby initiating the auditory and vestibular pathways. In order to achieve this, hair cells have developed anatomical and molecular specializations, such as the characteristic and name‐giving ‘synaptic ribbons’ – presynaptically anchored dense bodies that tether SVs prior to release – as well as other unique or unconventional synaptic proteins. The tightly orchestrated interplay between these molecular components enables not only ultrafast exocytosis, but similarly rapid and efficient compensatory endocytosis. So far, the knowledge of how endocytosis operates at hair cell ribbon synapses is limited. In this Review, we summarize recent advances in our understanding of the SV cycle and molecular anatomy of hair cell ribbon synapses, with a focus on cochlear inner hair cells.
Advertising
Authors: Hallahan Kirk
Published: September 2018

Advertising is both a function of and tool used in strategic communication. Narrowly defined, advertising involves the purchase of paid space or time in newspapers, magazines, radio, television, out‐of‐home media, the World Wide Web, or mobile apps to communicate strategically crafted messages to targeted audiences. More broadly, it can include direct response, sales promotion, and elements of publicity and staged events. Advertising can be produced by either an advertising department or an advertising agency. Advertising strategy includes both creating effective messages and deploying them in media to optimize efficiency and effectiveness. Advertising faces a variety of challenges as a strategic communication tool, including high costs, concerns about credibility, the internationalization of brands, criticisms about its truthfulness and the values communicated, and rapid changes in media technologies.
Advocacy, Internal and External
Authors: Hoffjann Olaf
Published: September 2018

In general terms, advocacy means publicly providing support for some interest, organization, or issue position. External advocacy can generally be understood as the act of publicly representing an individual, organization, or idea with the object of persuading targeted audiences to look favorably on the individual, organization, or idea. Thus, the goal of external advocacy is to give an organization a voice in the marketplace of ideas, facts, and viewpoints. Internal advocacy, on the other hand, represents the views of external stakeholders in the organization and thus brings external views into the organization. In so doing, internal advocacy allows the organization to respond to and adjust to meet the demands of societal changes. External advocacy in particular has long been criticized as manipulation and propaganda. As a result, for several years now, there has been intense debate surrounding the question of how ethical and responsible advocacy might look.
