Rational water use indicators for public schools in Recife, Brazil
Authors: Nunes Luiz Gustavo Costa Ferreira , Soares Anna Elis Paz , da Silva Juliana Karla , da Silva Simone Rosa 
Published: April 2018

Abstract
This paper seeks to propose rational water use indicators for public schools in Recife, Brazil. The methodology consists of a cadastral survey, the use of questionnaires, and identification of leakage in the hydro-sanitary facilities. The results indicate that even though water consumption is not as high as pointed out in the literature, the schools still present a considerable amount of physical water losses, in addition to having a low perception regarding the rational use of water. Based on these results, this study supports the development and application of water conservation actions within the school environment.

Authors: Eroğlu Mehmet E. , Bayraktepe Dilek E. , Polat Kamran , Yazan Zehra 
Published: April 2018

Background:
Electrochemical oxidation mechanism and electrochemical determination of meloxicam
(M), an anti-artrithtis agent, were investigated by cyclic voltammetry and square wave adsorptive
stripping voltammetry, respectively.
</P><P>
Objective: In this study, we aimed to investigate the electrochemical redox mechanism and develop a
nano-sensor for sensitive, fast and selective analysis of meloxicam.

Methods:
In this study, the three-electrode system was used for all voltammetric measurements. Firstly,
the graphene content of GR/CPE sensor was changed in the range of 1.67% to 6.68%. Then, the surface
characterization of modified electrode was carried out by using Electrochemical Empedance Spectroscopy
and Surface Electron Microscopy methods. Some analytical parameters, such as pH, accumulation
potential and accumulation time were optimized and by using optimum parameters, calibration study
was established.

Results:
The GR/CPE with a graphene content of 3.33 % was found to have the best voltammetric signal
with a linear working range of 0.1–10 µM. The sensitivity of the quantitative voltammetric method
towards M is fairly good with an LOQ of 0.0088 μmol/L and LOD of 0.0026 µmol/L.

Conclusion:
The optimum pH, accumulation time and accumulation potential were found to be 2.0,
150s and 0.0 V, respectively. The height of the voltammetric signal obtained with the GR/CPE electrode
was stable with a 4.0 % deviation for a period of not shorter than 1 months.
HCVS: Pinpointing Chromatin States Through Hierarchical Clustering and Visualization Scheme
Authors: Noureen Nighat , Fazal Sahar , Qadir Muhammad Abdul , Afzal Muhammad Tanvir 
Published: April 2018

Background:
Specific combinations of Histone Modifications (HMs) contributing towards
histone code hypothesis lead to various biological functions. HMs combinations have been utilized by
various studies to divide the genome into different regions. These study regions have been classified as
chromatin states. Mostly Hidden Markov Model (HMM) based techniques have been utilized for this
purpose. In case of chromatin studies, data from Next Generation Sequencing (NGS) platforms is being
used. Chromatin states based on histone modification combinatorics are annotated by mapping them to
functional regions of the genome. The number of states being predicted so far by the HMM tools have
been justified biologically till now.

Objective:
The present study aimed at providing a computational scheme to identify the underlying
hidden states in the data under consideration.
</P><P>
Methods: We proposed a computational scheme HCVS based on hierarchical clustering and
visualization strategy in order to achieve the objective of study.

Results:
We tested our proposed scheme on a real data set of nine cell types comprising of nine
chromatin marks. The approach successfully identified the state numbers for various possibilities. The
results have been compared with one of the existing models as well which showed quite good
correlation.

Conclusion:
The HCVS model not only helps in deciding the optimal state numbers for a particular data
but it also justifies the results biologically thereby correlating the computational and biological aspects.

New scientific spirit and new epistemology: a More poietic point of view of education and knowledge
Authors: Lanzarini Joice Nunes , Probst Melissa 
Published: April 2018

ABSTRACT The positivist science model has been influencing Education for more than three centuries. The belief that guides such model separates the intelligible world, as the most important, which, deals with science, intelligence and the brain from the sensitive world, one-step down in importance, which, deals with sensitive experiences and emotions. The application of such epistemological concepts helped to build the current education model. The current education conceptions indicate an urgency in seeking, not only new methodology theories, but also the construction of an educational concept more connected to modern times demands. The work of Gaston Bachelard is considered one of the most important regarding the twentieth century science revolution when it comes to a new creative poetic construction with several points of view. The following paper tries, briefly, to use the ideas presented by Bachelard in his book “The new scientific spirit” and relate them to the proposal of a poetic point of view regarding education and knowledge by setting a dialogue with other authors who developed their considerations from Bachelard as well. Keywords: Education. Epistemology. Complexity. Bachelard. DOI: http://dx.doi.org/10.22169/revint.v12i27.1069
A filosofia como atitude crítica da produçao de si na educação tecnológica
Authors: Vandresen Daniel Salésio , Gelamo Rodrigo Pelloso 
Published: April 2018

O objetivo desse artigo é realizar um diagnóstico da educação tecnológica utilizando como ferramenta as noções de biopolítica e ontologia do presente desenvolvidos por Michel Foucault. A partir disso, problematizamos a educação tecnológica dos Institutos Federais analisando sua concepção de ensino baseada na noção de trabalho como princípio educativo. Constata-se que a educação tecnológica não tem pensado a vida para além da formação profissional ou, melhor, tem se preocupado apenas com a parte da vida que é determinada pela sua condição cotidiana da utilidade e do trabalho. Por fim, desenvolve-se o conceito de atitude crítica para pensar uma prática filosófica que dá forma à impaciência da liberdade e permite a resistência aos saberes de sujeição próprios da tecnicidade biopolítica. Palavras-chave: Biopolítica; Ontologia de nós mesmos; Filosofia; Educação tecnológica. ABSTRACT The objective of this article is to make a diagnosis of technological education by using, as a tool, the current notions of biopolitics and ontology developed by Michel Foucault. Thus, the authors problematized the technological education of the Institutos Federais analyzing their conception of education based on the notion of work as an educational principle. It is clear technological education has not thought about life beyond vocational training or, rather, has been concerned only with the part of life that is determined by its daily use and work. Finally, the concept of critical attitude is developed to consider a philosophical practice that gives form to the impatience of freedom and allows the resistance to servitude knowledge inherent to biopolitical technicity. Keywords: Biopolitics; Oneself Ontology; Philosophy; Technological education. RÉSUMÉ L'objectif de cet article est de faire un diagnostic de l'éducation technologique en utilisant comme outil les notions de biopolitique et d'ontologie du présent développé par Michel Foucault. De ce fait, nous problématisons l'éducation technologique des Institutos Federais en analysant leur conception de l'éducation fondée sur la notion de travail en tant que principe pédagogique. On peut voir que l'éducation technologique n'a pas pensé à la vie au-delà de la formation professionnelle, mais plutôt qu'elle ne concerne que la partie de la vie qui est déterminée par sa condition quotidienne d'utilité et de travail. Enfin, le concept d'attitude critique est développé pour penser une pratique philosophique qui donne forme à l'impatience de la liberté et permet la résistance à la connaissance de l'assujettissement propre à la technicité biopolitique.

Authors: Huang Feiqi , Li He , Wang Tawei 
Published: April 2018

SYNOPSIS
Prior literature has firmly established the relationship between IT capability and firm performance. In this paper, we extend the research in this field and investigate (1) whether IT capability contributes to management forecast accuracy, and (2) whether IT capability improves the informativeness of management forecasts and enhances the extent to which analysts incorporate management forecasts in their revisions. Using firms listed on InformationWeek 500 as our high IT capability group, we empirically demonstrate that firms with high IT capability are able to increase management forecast accuracy, and that analysts incorporate more information from management forecasts in their revisions if the firm has high IT capability.
