<p>A orientação acadêmica ou tutoria na educação a distância (EAD), segundo Neder (2000), é um dos elementos do processo educativo que possibilita a (res)significação da educação, principalmente ao permitir o rompimento da noção de tempo/espaço da escola tradicional. Os tutores desempenham a função de mediação entre os conteúdos das disciplinas e os alunos e estabelecem relações entre alunos e professores e entre os próprios alunos. Dada a importância desta função acadêmica, procurou-se investigar o quanto a prática da tutoria aproxima-se da visão, de certa forma idealizada, presente na literatura sobre educação a distância. Por<br />meio de entrevistas com nove alunos e 31 tutores do curso de Administração na modalidade a distância (EAD), da Universidade Federal do Espírito Santo (UFES), projeto piloto da Universidade Aberta do Brasil (UAB), em quatro momentos distintos, de dezembro/2007 a<br />março/2009, buscou-se identificar aprendizados e desafios da tutoria na educação a distância. As análises realizadas possibilitaram compreender que a tutoria ainda é mal compreendida por alunos e tutores e que as dificuldades de adaptação ainda são grandes. O principal desafio a ser<br />vencido é a ruptura com o paradigma tradicional de ensino e a aceitação de um paradigma focado na relação dialógica tutor-aluno.<br /><br /></p>

<p>Este estudo tem como objetivo identificar a hierarquia dos valores básicos de estudantes de graduação em Administração de Empresas de duas universidades. Para suportar tal investigação foi utilizada a Teoria de Valores Básicos, de Schwartz. A metodologia adotada compreendeu uma pesquisa tipo exploratória descritiva, quantitativa, com a aplicação do<br />Portrait Value Questionnaire (PVQ), em amostra final válida composta por 208 casos. Os resultados mostram prioridade para o tipo motivacional Universalismo, que mostra uma preocupação em entender e apreciar o funcionamento das coisas, seguindo uma conduta de tolerância e proteção para o todo; seguido do tipo motivacional Poder, indicando desejo de<br />status social e vencer na vida. A análise comparativa mostra que, enquanto os estudantes da Universidade A estão mais preocupados com posição profissional e social, os estudantes da Universidade B valorizam mais a diversão, prazer e curiosidade, ao mesmo tempo em que prezam pela segurança. Os achados deste trabalho podem contribuir com um melhor direcionamento de formas de ensino. Para uns, deve-se estimular os desafios e aprendizagem com prazer num ambiente de convívio social favorável; para outros, deve-se enfatizar as oportunidades que lhes dêem caminhos reais para o desenvolvimento profissional.<br /><br /></p>

Published: May 2015

<p>A AR Consultoria Ltda., dos sócios e irmãos Alfredo e Rodolfo, especializada na venda de produtos químicos e na prestação de serviços para agroindústrias, nasceu com base em uma oportunidade visualizada por Rodolfo, tornar-se fornecedor da empresa em que trabalhava. Funcionário de uma agroindústria da cidade de Chapecó/SC possuía conhecimentos técnicos e uma ótima relação com seus colegas superiores e subordinados. Procurou a empresa na qual era funcionário e ofereceu produtos similares, mais eficientes e com preços menores aos<br />praticados pelos fornecedores atuais, mas se deparou com algo que não tinha conhecimento: a corrupção. Surgira o primeiro desafio ético da AR Consultoria: o pagamento de um “extra por fora” para se tornar fornecedor. Alfredo, recém-formado em Administração, empolgado com a possibilidade e oportunidade de empreender, aos poucos conheceu as dificuldades em iniciar um negócio próprio, a alta carga tributária, falta de incentivos, falta de crédito no mercado e a oportunidade de “ganhar um pouco mais” vendendo sem nota fiscal. Essas e outras situações marcaram as dificuldades de início da abertura de mercado da AR Consultoria Ltda. O objetivo do caso é apresentar uma situação real, presente em alguns ramos e setores organizacionais<br />e que exija do leitor uma tomada de decisão, uma postura ética diante dos desafios morais apresentados.<br /><br /></p>

Abstract

BACKGROUND
Malaria control programs have achieved remarkable success during the past decade. Nonetheless, sensitive and affordable methods for active screening of malaria parasites in low-transmission settings remain urgently needed.

METHODS
We developed a molecular screening method, capture and ligation probe-PCR (CLIP-PCR), which achieved the sensitivity of reverse-transcription PCR but eliminated the reliance on RNA purification and reverse transcription. In this method, 18S rRNA of genus Plasmodium is released from blood, captured onto 96-well plates, and quantified by the amount of ligated probes that bind continuously to it. We first used laboratory-prepared samples to test the method across a range of parasite densities and pool sizes, then applied the method to an active screening of 3358 dried blood spot samples collected from 3 low-endemic areas in China.

RESULTS
Plasmodium falciparum diluted in whole blood lysate could be detected at a concentration as low as 0.01 parasites/μL, and a pool size of ≤36 did not significantly affect assay performance. When coupled with a matrix pooling strategy, the assay drastically increased throughput to thousands of samples per run while reducing the assay cost to cents per sample. In the active screening, CLIP-PCR identified 14 infections, including 4 asymptomatic ones, with &lt;500 tests, costing &lt;US$0.60 for each sample. All positive results were confirmed by standard quantitative PCR.

CONCLUSIONS
CLIP-PCR, by use of dried blood spots with a pooling strategy, efficiently offers a highly sensitive and high-throughput approach to detect asymptomatic submicroscopic infections with reduced cost and labor, making it an ideal tool for large-scale malaria surveillance in elimination settings.
Period, History, and the Literary Art: Historicizing Amharic Novels
Authors: Gebre Tewodros 
Published: May 2015

Abstract
The period between 1960 (the failed coup) and 1974 (the successful military takeover of power), was a momentous segment of contemporary Ethiopian history. It was an era teeming with social unrest among various social classes and strata of society. It is a very concentrated period full of accidents and coincidences that were melodramatic and absurd, and which mostly ended tragically. This made it particularly suitable for Ethiopian literary art. The most esteemed works of art in Amharic literature and source of incitement even for the present academia are products of this period—Fəqər əskä mäqabər, YäTéwodros ənba, Adäfrəs, Ke'admas bashaggär, and Létum aynägalləñ. This article argues that these novels are highly affected by the prevailing spirit of their time—the mood of confusion, ambivalence, fragmentation, and the spirit of anarchy and nihilism The novels, like other cultural products and activities, were initiated by the past, but they employed it to distill the abstract spirit of the times that were unnoticed by their society. They attempted to shape the era itself. This article's focus is not solely the “historicity of texts.” History here is not simply a backdrop against which the literary works are to be viewed but itself constituent of the text, inscribed in the text as one component.
Sisters Debating the Jesuits: The Role of African Women in Defeating Portuguese Proto-Colonialism in Seventeenth-Century Abyssinia
Authors: Belcher Wendy Laura 
Published: May 2015

Abstract
Many assume that African women did not play an intellectual or political role before the modern period. Taking advantage of rare sources in Portuguese, Latin, and Gəʿəz, this article analyzes European and African texts written in the 1600s about Ethiopian royal women who led their people in resisting Portuguese proto-colonialism. The texts display quite different perspectives on the women, but they agree that women participated in defeating this European incursion. Comparing the two traditions reveals that the negative Portuguese representations of these Ethiopian royal women were not just the result of misogyny, but were a vanquished foe's bitter depiction of a victorious enemy. Indeed, these early modern African women must be acknowledged as some of the earliest pioneers against European incursions in Africa. This article focuses on the extraordinary, larger-than-life stories of six such women.
Research Papers. An Approach to Design Broadband Air Backed Piezoelectric Sensor

Published: May 2015

Abstract
In this work, an approach to the design of broadband thickness-mode piezoelectric transducer is pre- sented. In this approach, simulation of discrete time model of the impulse response of matched and backed piezoelectric transducer is used to design high sensitivity, broad bandwidth, and short-duration impulse response transducers. The effect of matching the performance of transmitting and receiving air backed PZT-5A transducer working into water load is studied. The optimum acoustical characteristics of the quarter wavelength matching layers are determined by a compromise between sensitivity and pulse duration. The thickness of bonding layers is smaller than that of the quarter wavelength matching layers so that they do not change the resonance peak significantly. Our calculations show that the −3 dB air backed transducer bandwidth can be improved considerably by using quarter wavelength matching layers. The computer model developed in this work to predict the behavior of multilayer structures driven by a transient waveform agrees well with measured results. Furthermore, the advantage of this this model over other approaches is that the time signal for optimum set of matching layers can be predicted rapidly
A Revised Sound Energy Theory Based on a New Formula for the Reverberation Radius in Rooms with Non-Diffuse Sound Field
Authors: Arau-Puchades Higini , Berardi Umberto 
Published: May 2015

Abstract
This paper discusses the concept of the reverberation radius, also known as critical distance, in rooms with non-uniformly distributed sound absorption. The reverberation radius is the distance from a sound source at which the direct sound level equals the reflected sound level. The currently used formulas to calculate the reverberation radius have been derived by the classic theories of Sabine or Eyring. However, these theories are only valid in perfectly diffused sound fields; thus, only when the energy density is constant throughout a room. Nevertheless, the generally used formulas for the reverberation radius have been used in any circumstance. Starting from theories for determining the reverberation time in non- diffuse sound fields, this paper firstly proposes a new formula to calculate the reverberation radius in rooms with non-uniformly distributed sound absorption. Then, a comparison between the classic formulas and the new one is performed in some rectangular rooms with non-uniformly distributed sound absorption. Finally, this paper introduces a new interpretation of the reverberation radius in non-diffuse sound fields. According to this interpretation, the time corresponding to the sound to travel a reverberation radius should be assumed as the lower limit of integration of the diffuse sound energy
Halogenation of β-estradiol by a rationally designed mesoporous biocatalyst based on chloroperoxidase
Authors: Salcedo Karina , Torres-Ramírez Eduardo , Haces Iliana , Ayala Marcela 
Published: May 2015

AbstractChloroperoxidase from Caldariomyces fumago was immobilized in Eupergit® C, a commercial mesoporous acrylic-based material. Due to low stability of the enzyme under neutral and basic pH, the usual covalent immobilization procedures cannot be applied to this enzyme. Several strategies were followed in order to achieve a stable interaction between the protein and the support. The support was efficiently functionalized with different reactive groups such as aromatic and aliphatic amines, glutaraldehyde, diazonium ions, and maleimide moieties; solvent-exposed amino acid residues in chloroperoxidase were identified or created through chemical modification, so that they were reactive under conditions where the enzyme is stable. Enzyme load and retained activity were monitored, obtaining biocatalysts with specific activity ranging from 200 to 25,000 U/g. The highest load and activity was obtained from the immobilization of a chemically-modified CPO preparation bearing a solvent-exposed free thiol group. This biocatalyst efficiently catalyzed the transformation of β-estradiol, an endocrine disruptor.
Clinical relevance of sST2 in cardiac diseases
Authors: Pascual-Figal Domingo A. , Lax Antonio , Perez-Martinez Maria Teresa , del Carmen Asensio-Lopez Maria , Sanchez-Mas Jesus , on behalf of GREAT Network  
Published: May 2015

AbstractST2 has two main isoforms, ST2L and soluble isoform of ST2 (sST2), by alternative splicing. The interaction between interleukin (IL)-33 and the transmembrane isoform ST2L is up-regulated in response to myocardial stress and exerts cardio-protective actions in the myocardium by reducing fibrosis, hypertrophy and enhancing survival. The circulating isoform sST2, by sequestering IL-33, abrogates these favorable actions and will be elevated as a maladaptive response to cardiac diseases. Indeed, circulating sST2 concentrations correlate with a worse phenotype of disease including adverse remodeling and fibrosis, cardiac dysfunction, impaired hemodynamics and higher risk of progression. In patients with acute and chronic heart failure, sST2 concentrations are strongly predictive of death, regardless of the cause and left ventricle (LV) ejection fraction, and contribute relevant information in addition to other prognosticators and biomarkers, as natriuretic peptides or troponins. sST2 also retains prognostic information in the setting of acute myocardial infarction (AMI) and predicts cardiovascular death and risk of heart failure (HF) development in these patients. sST2 could also be a promising tool to stratify the risk of sudden cardiac death (SCD) in patients with depressed LV ejection fraction. Therefore, sST2 represents a clinically relevant biomarker reflecting pathophysiological processes and contributing predictive information in the setting of several cardiovascular diseases, and especially in patients with HF.
Niobia supported on silica as a catalyst for Biodiesel production from waste oil

Published: May 2015

AbstractThe activity and stability of niobia supported
on silica catalyst have been tested in continuous
micro-pilot reactors, for biodiesel production starting
from acid vegetable oils. A catalyst was prepared
by the impregnation of silica pellets with a loading
of 12% of Nb and was extensively characterized.
The activity of this catalyst in both esterification and
transesterification was tested in a continuous micro-pilot
laboratory plant in which acid oil was fed (FFA 10% w/w)
at a temperature of 220°C and at a pressure of 60 bar.
The niobia based catalyst resulted in a very active
catalyst in both esterification (FFA conversion =
95-90%) and transesterification reactions (FAME
yield = 80-90%), and the activity remained
quite constant for more than 100 h on stream.
Notwithstanding this stability, a non-negligible leaching
phenomena has been detected, in the case of long-time
continuous runs, as the Nb concentration on the spent
catalyst resulted lower than that on the fresh one. The
obtained result confirms that the leaching of the active
specie is one of the most strong problem in heterogeneous
catalysis for biodiesel production.

Abstract
Developments in “-omics” are creating a paradigm shift in laboratory medicine leading to personalized medicine. This allows the increase in diagnostics and therapeutics focused on individuals rather than populations. In order to investigate whether laboratory medicine is ready to play a key role in the integration of personalized medicine in routine health care and set the state-of-the-art knowledge about personalized medicine and laboratory medicine in Europe, a questionnaire was constructed under the auspices of the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) and the European Society of Pharmacogenomics and Personalised Therapy (ESPT). The answers of the participating laboratory medicine professionals indicate that they are aware that personalized medicine can represent a new and promising health model, and that laboratory medicine should play a key role in supporting the implementation of personalized medicine in the clinical setting. Participants think that the current organization of laboratory medicine needs additional/relevant implementations such as (i) new technological facilities in -omics; (ii) additional training for the current personnel focused on the new methodologies; (iii) incorporation in the laboratory of new competencies in data interpretation and counseling; and (iv) cooperation and collaboration among professionals of different disciplines to integrate information according to a personalized medicine approach.
