Published: October 2018

This paper describes a facile one-step method for synthesizing native or ethyl carbamate modified Field’s alloy nanoparticles based on nano-emulsification technique. The size, morphology and zeta potential of as-prepared native or modified Field’s alloy nanoparticles were characterized by atomic force microscopy (AFM), dynamic light scattering (DLS) and zeta potential analyzer, respectively. A portable ultraviolet–visible (UV-Vis) spectrometer coupled with fiber optics is used to continuously monitor optical transparency of the native and ethyl carbamate modified nanofluid at certain wavelength, which can be used to evaluate the stability of the nanoparticle in the poly-alpha-olefin (PAO) oil. The thermal properties of nanoparticles and nanofluid (native or ethyl carbamate modified Field’s alloy nanoparticles dispersed in PAO) were investigated by differential scanning calorimetry (DSC). Results show that the nanofluid with modified nanoparticles exhibits good thermal properties and stability, which shows promising potential applications in cooling of electronic device, engines and other systems.

Industry clusters provide not only economic benefits, but also promote technological innovation through networking within a cluster. In this study, we analyze the mechanism of explicit and tacit knowledge diffusion in a cluster and how the network structure and the strength of ties influence the process of explicit and tacit knowledge diffusion. By focusing on four representative real-world networks – scale-free, small world, regular, and random – and the strength of ties between firms, the knowledge diffusion performance of entire organizations in a cluster is examined by the simulation method. We find that the network structure of clusters and the strength of ties are important for the knowledge diffusion performance in clusters. Among the four networks, the scale-free network shows the best knowledge diffusion performance, irrespective of the proportion of strong and weak ties present. In addition, the network with a greater number of strong ties leads to the explicit and tacit knowledge diffusion performance.

Authors: Hu Xiaowen ,   School of Economic and Management, Anhui Normal University 189 Huajin South Road, Wuhu City, Anhui 241002, China, Hu Chengchen , Yao Yiyu
Published: October 2018

Modeling the effect of uncertainty shock usually employs VAR method. The approach however often leads to the results unstable with different structural equations. Especially it is modeled without a microscopic basis which often implies wrong policy advice. A new method to model the effect of interest rate uncertainty is proposed in this paper that overcomes this limitation. A stochastic volatility model is embedded into a dynamic stochastic general equilibrium framework to study the influence of interest rate uncertainty on the residents’ consumption. Using the third-order perturbation method to identify the impact of interest rate uncertainty on consumption. It is found by simulation that with the interest rate uncertainty increased, the consumption of residents in the current period has obviously decreased due to the preventive saving mechanism. Variance analysis shows that interest rate uncertainty shocks can explain 8% share of consumption volatility. The empirical results are robust when changing the parameter values and the prior distribution of the parameters. The conclusion shows the government should strengthen to guide the public reasonable expectations, to avoid the negative impact of interest rate uncertainty.

In order to provide a unified platform for fuzzy inference and fuzzy rule learning with noise-corrupted data, a method is proposed for reducing noise in learning data on the basis of a fuzzy inference method called α-GEMINAS (α-level-set and generalized-mean-based inference with fuzzy rule interpolation at an infinite number of activating points). It is expected to prevent fuzzy rules from overfitting to noise in learning data, especially when there is less learning data available for fuzzy rule optimization. The proposed method is named α-GEMI-ES (α-GEMINAS-based local-evolution toward slight linearity for global smoothness) in this paper. α-GEMI-ES iteratively performs α-GEMINAS and reduces the noise in each iteration. This paper mathematically proves that α-GEMI-ES effectively reduces the noise. The noise-reduction process is decisive and thus relies less on trial-and-error-based progress. The noise is reduced by a large amount in the early iterations and the amount of its reduction is decelerated in the later iterations where the deviation in the learning data is suppressed to a great extent. This property makes it easy to determine the termination conditions for the iterative process. Simulation results demonstrate that α-GEMI-ES properly reduces noise as the mathematical proof suggests. The above-mentioned properties indicate that α-GEMI-ES is feasible in practice for the unified platform.

Representing the positive, possible, and boundary regions of clusters, rough set-based C-means clustering methods, such as generalized rough C-means (GRCM) and rough set C-means (RSCM), are promising for analyzing vague cluster shapes and realizing reliable classification. In this study, we consider rough set-based clustering approaches that utilize probabilistic memberships as variants of GRCM and RSCM, including π generalized rough C-means (πGRCM), π rough set C-means (πRSCM), and rough membership C-means (RMCM). πGRCM and πRSCM assign equal probabilities of cluster belonging according to Laplace’s principle of indifference, whereas RMCM assigns the probabilities according to rough memberships, which represent conditional probabilities based on the object’s neighborhood derived from a binary relation. In addition, we discuss the theoretical validity of our RMCM approach and compare it with other methods considered in this study. Furthermore, we conducted numerical experiments for evaluating the classification performances of the abovementioned methods. Based on our experimental results, the methods were found to be effective.

Published: October 2018

With the rapid development of the Internet and travel market, the availability of online short-term rental rooms has emerged, making good use of limited room resources. In current research, only structured data of room characteristics, such as the location of the room, are considered in the price of the room. As unstructured textual data, online user’s reviews containing the emotional responses of users influence the price of online short-term rental rooms. In this research, user reviews are considered in a hedonic price regression model to improve the performance of regression. First, structured room characteristics are input to build a traditional hedonic price regression model. Then, fusion of emotion scores transformed from unstructured user reviews is input to build a fusion hedonic price regression model. Finally, the traditional model and the fusion model are compared statistically. Experimental results indicate that the fusion of user reviews can improve the performance of hedonic price regression model.

Published: October 2018

Resources and the environment have always been the two important natural factors that affect people’s lives. In recent years, the problem of resources and the environment has increasingly become an important issue that people are concerned about. This study discusses the use and consumption of energy and the impact of environmental pollution on economic development under sustainable economic development. This paper takes Panzhihua as an example to analyze the impact of energy and environment on the economy, and proposes solutions to improve economic development, which is of strategic significance for the future development of Panzhihua City. In this paper, the system dynamics method is used to decompose the Panzhihua large-scale system into three parts and carry out modeling and simulation to explore the connection between them. Based on the data from 2007 to 2015 in Panzhihua City, simulations have been carried out to obtain qualitative and quantitative analysis of certain simulation curves of the energy-environment-economy 3E system (hereinafter referred to as 3E system) from 2007 to 2030 to ascertain the future development pattern of Panzhihua City. The results show that when the 3E system is a coordinated development model, economic development and environmental protection have a good development trend at the same time, which is applicable to the future development of Panzhihua City. This model has good reference suggestions and application prospects for urban development. We want to give Panzhihua City the following suggestions: (1) Continue to focus on the secondary industry and increase competitiveness. (2) Increase the investment funds in environmental protection and achieve sustainable economic development.

in ordinary differential equations
Authors: Pandey P.K.
Published: October 2018

In this article, we propose a new computational method for second order initial value problems in
ordinary differential equations. The algorithm developed is based on a local representation of theoretical solution of the second order initial value problem by a non-linear interpolating function. Numerical examples are solved to ensure the computational performance of the algorithm for both linear and non-linear initial value problems. From the results we obtained, the algorithm can be said computationally efficient and effective.

Authors: Vajravelu Kuppalapalle , Li Ronald , Dewasurendra Mangalagama , Benarroch Joseph , Ossi Nicholas , Zhang Ying , Sammarco Michael , Prasad K.V.
Published: October 2018

In this paper, boundary layer flow over a moving flat plate with second-order velocity slip, injection and applied magnetic field is analyzed. The governing partial differential equations are converted in to a nonlinear ordinary differential equation through an appropriate similarity transformation. The resulting nonlinear equation is solved via homotopy analysis method (HAM). Errors ranging from 10–7 to 10–10 are reported for a relatively few terms. The effects of the pertinent parameters on the velocity and the shear stress are presented graphically and discussed. In the absence of magnetic field and the two slip parameters, the results are found to be in excellent agreement with the available results in the literature. It is expected that the results obtained will not only provide useful information for industrial applications but also complement the earlier works.
A calculus course in knowledge feedback format
Authors: Lennerstad Håkan
Published: October 2018

This paper presents a design of an undergraduate calculus course which attempts to achieve higher student activity and teacher-student exchange, allowing the teacher to adapt more to the present student group and to increase students work time. This is done by switching between examinations in small format and examination-free, open mathematical dialogue occasions – two learning-enhancing opposites that reinforce each other during the course. In the examination-free dialogue, students solved problems during lectures every week, where the quality of the student-teacher dialogue is essential both for dissection of properties of mathematics and for students’ willingness to continue participating. Thus, students regularly practiced verbal presentation and reflection in mathematics.
A Coreflooding-NMR Study of Gel Conformance Control in Fractured Systems
Authors: Alshehri Amar J. , Wang Jinxun , Kwak Hyung T. , AlSofi Abdulkarim M.
Published: October 2018

Conformance control using polymer gels has been successfully used in both sandstone and carbonate reservoirs to improve sweep efficiency. A challenge in achieving successful gel placement away from the well is reservoir high temperature. In such envrionments, a thourgh understanding of the gel system and its behavior in heterogenous reservoirs along with enhancing its performance is essential for a proper gel placement.

In this work, several coreflood experiments were conducted to assess the performance of polyacrylamide/chromium gel system in a high-temperature and high-salinity (HTHS) carbonate cores. The used cores were specially prepared with different configurations of high-permeability channels surrouned by rock matrix. The gel treatment was performed in a tertiary mode, and soaked at reservoir temperature for gelation, then followed by chase waterflooding. Nuclear magnetic resonance (NMR) techniques were used to monitor oil distribution throughout the coreflood experiments and determine sweep improvement due to the gel treatment. To improve the contrast between oil and brine/gel in NMR measurements, heavy water (D2O) was used as the aquous phase.

Results show that unrecovered oil in the matrix was effectively displaced after the gel treatment. This improvement could be attributed to viscous effects and/or fluid-diversion effects. Hence, a similar experiment was conducted using only polyacrylamide solutions (chromium crosslinker was not added) to quantify improvement due to viscous effects only.

This work demonstrates the potential of the studied gel system and its favorable impact on sweep efficiency improvement in HTHS carbonates. The NMR study shows how gel helps improve sweep efficiency of subsequent floods through blocking/reducing the permeability of highly-conductive zones. Moreover, a better understanding is achieved through proper attribution of viscous effects and fluid- diversion effects on improvement in oil displacement for gel treatments. It was found out that improvement in oil production due to viscous effects was very small compared to blockage or fluid- diversion effects.
Characterization of the Leaf Color Mutant hy and Identification of the Mutated Gene in Chinese Cabbage

Published: October 2018

Leaf color mutants play an important role in our understanding of chlorophyll biosynthesis and catabolism. In this study, we obtained a yellow-green leaf mutant hy in an ethyl methanesulfonate mutagenized population of chinese cabbage (Brassica rapa ssp. pekinensis). The hy phenotype was controlled by a recessive allele at a single locus. The intrinsic photochemical activity of photosystem II (PSII) is impaired in hy, suggesting that absorbed light energy is not efficiently transferred from the light-harvesting complexes antenna to the PSII reaction centers and dissipated as heat or fluorescence. We measured chlorophyll content and chlorophyll precursors and analyzed the expression of key genes in the chlorophyll synthetic pathway in hy and wild type. The mutation phenotype was consistent with inhibited expression of chlorophyll a oxygenase (CAO) gene in the chlorophyll synthetic pathway. In mutant hy, CAO cDNA was cloned so that a C to T mutation at 1099 bp caused a conserved proline (Pro) to serine (Ser) mutation at the 367th amino acid in C-domain, which changed the secondary structure of CAO protein. We speculate that the mutation amino acid changed in the C-domain may affect the catalytic function in mutant CAO.
Dark matter in anomaly-free gauge extensions
Authors: Bauer Martin , Diefenbacher Sascha , Plehn Tilman , Russell Michael , Camargo Daniel A.
Published: October 2018

A consistent model for vector mediators to dark matter needs to be
anomaly-free and include a scalar mode from mass generation. For the
leading U(1) extensions we review the structure and constraints,
including kinetic mixing at loop level. The thermal relic density
suggests that the vector and scalar masses are similar. For the LHC we
combine a \boldsymbol{Z'}𝐙′
shape analysis with mono-jets. For the latter, we find that a shape
analysis offers significant improvement over existing cut-and-count
approaches. Direct detection limits strongly constrain the kinetic
mixing angle and we propose a
\boldsymbol{\ell^+\ell^-\met}
search strategy based on the scalar mediator.

Authors: Varricchi Gilda , Pecoraro Antonio , Crescenzi Ludovica , Marone Giancarlo , Travaglino Antonio , D'Armiento Francesco Paolo , Genovese Arturo , Spadaro Giuseppe
Published: October 2018

Background:

Common variable immunodeficiency (CVID) encompasses a heterogeneous
group of primary antibody deficiency disorders characterized by recurrent infections, autoimmunity
and malignancies. Gastrointestinal manifestations are frequently associated with CVID.

Objective:

In this cross-sectional study, we evaluated gastric and duodenal involvement in a cohort of
adult patients with CVID.

Methods:

Upper gastrointestinal endoscopy was performed in 58 patients (26 males, mean age 47.8±15.6
years), diagnosed with CVID according to 2014 ESID criteria. Random biopsies were collected from gastric
antrum and descending duodenum for the all enrolled subjects. Intraepithelial lymphocytosis in descending
duodenum was defined as the presence of 25 lymphocytes per 100 enterocytes.

Results:

The major histopathological findings that we found were: a) chronic active gastritis (44.8%),
Helicobacter pylori-associated (8.6%), b) chronic duodenitis (39.6%) with intraepithelial lymphocytosis
(31%) and absence of plasma cells (18.9%) and c) autoimmune atrophic gastritis (5.2%). Three patients
(5.2%) presented Intestinal Metaplasia (IM) of the gastric antrum. This finding was associated
with H. pylori infection and persisted after the eradication in one patient. IM was associated with autoimmune
atrophic gastritis in two cases. Giardia lamblia infection was observed in the duodenum samples
from three patients (5.2%). A diagnosis of Gastric adenocarcinoma was made in a 58-year- old
woman diagnosed with gastric dysplasia one year earlier.

Conclusion: In our cohort of CVID patients, gastro-duodenal histopathological findings, including malignancies,
are frequent and can affect long-term prognosis. A rigorous endoscopic follow-up is needed
in CVID patients irrespective of the gastrointestinal symptoms.

Authors: Iqbal Khurshid , Imran Muhammad , Ullah Shafi , Jamal Muhsin , Waheed Yasir
Published: October 2018

Background:

Human immunodeficiency virus (HIV) infection is a global health burden
which ultimately results in acquired immune deficiency syndrome (AIDS). There are multiple host
factors which are capable of limiting HIV-1 replication. One of the most important host factors
which inhibit HIV-1 DNA synthesis is the apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-
like 3G (APOBEC3G). Any genetic variation of this important host factor may influence the
host susceptibility to viral infection.

Objective:

The aim of the current study was to evaluate any correlation of APOBEC3G genetic
variation rs8177832 with HIV-1 infection.

Methods:

The study involved 142 healthy control and 100 HIV-1 infected subjects. The genetic
variation rs8177832 of all studied subjects was determined by allele-specific polymerase chain reaction
(AS-PCR).

Results:

The results showed that the distribution of rs8177832 genotypes AA, AG and GG in
healthy subjects and HIV-1 subjects was; 42.253%, 42.957%, 14.788% and 66%, 27%, 7% respectively.
Statistical analyses of data showed that there was a significant variation in rs8177832 genotype
AA in healthy control and HIV-1 infected subjects (42.257% vs 66%; p-value<0.001).

Conclusion:

Thus it was concluded that APOBEC3G rs8177832 AA genotype contributes in genetic
predisposition to HIV-1 infection in Pakistani population.

Published: October 2018

El desarrollo de la ciencia y la tecnología tiene una serie de matices por parte de quienes se encargan de la investigación en el campo científico. El presente ensayo tiene como propósito reflexionar sobre el concepto de trayectoria de Pierre Bourdieu aplicado en la carrera académica de profesores universitarios. Se analiza la trayectoria como elemento que configura el habitus del científico. Estas distinciones permiten apuntalar el capital cultural de los individuos/distinguidos y, de esta manera, se convierten en una persona excepcional; es una especie de trampolín que impulsa a otro campo, coloca en una posición mejor dotada en ese campo, en términos económicos, culturales y científicos. En ese sentido, se describe el concepto de campo científico desde una perspectiva bourdiana, la cual permite distinguir la manera en la que se posicionan los actores en dicho campo, las normas y sus distinciones. Por último, se plantean reflexiones relacionadas con la configuración de científicos y su producción, estableciendo la ubicación de las posiciones y condiciones que existen para el desarrollo de la ciencia y la tecnología en México.

El lenguaje metafórico del dominicano
Authors: Cuevas Persi Raquel
Published: October 2018

La metáfora es un recurso lingüístico que ayuda a interpretar el mundo, al asignarle significados a conceptos según el contexto en que se emplee. Los dominicanos nos valemos de este recurso y utilizamos expresiones metafóricas en la vida cotidiana como una forma de explicar la realidad; estas expresiones “populares” reflejan formas de pensamiento complejo, además de la existencia humana desde una metáfora. Este ensayo pretende sustentar la relación entre las metáforas y la lingüística cognitiva, para luego presentar la forma peculiar de hablar de los dominicanos e intentar esquematizar las metáforas utilizadas por categorías. En las conclusiones se apreciará la forma de hablar de un pueblo desde la utilización de la metáfora como forma predominante de expresión en su discurso oral. El corpus metafórico que se pretende construir en el ensayo es puramente dominicano y se ven representados los recursos lingüísticos empleados en cada metáfora que utilizamos los hablantes del español dominicano.
The boundaries and twist defects of the color code and their applications to topological quantum computation
Authors: Kesselring Markus S. , Pastawski Fernando , Eisert Jens , Brown Benjamin J.
Published: October 2018

The color code is both an interesting example of an exactly solved topologically ordered phase of matter and also among the most promising candidate models to realize fault-tolerant quantum computation with minimal resource overhead. The contributions of this work are threefold. First of all, we build upon the abstract theory of boundaries and domain walls of topological phases of matter to comprehensively catalog the objects realizable in color codes. Together with our classification we also provide lattice representations of these objects which include three new types of boundaries as well as a generating set for all 72 color code twist defects. Our work thus provides an explicit toy model that will help to better understand the abstract theory of domain walls. Secondly, we discover a number of interesting new applications of the cataloged objects for quantum information protocols. These include improved methods for performing quantum computations by code deformation, a new four-qubit error-detecting code, as well as families of new quantum error-correcting codes we call stellated color codes, which encode logical qubits at the same distance as the next best color code, but using approximately half the number of physical qubits. To the best of our knowledge, our new topological codes have the highest encoding rate of local stabilizer codes with bounded-weight stabilizers in two dimensions. Finally, we show how the boundaries and twist defects of the color code are represented by multiple copies of other phases. Indeed, in addition to the well studied comparison between the color code and two copies of the surface code, we also compare the color code to two copies of the three-fermion model. In particular, we find that this analogy offers a very clear lens through which we can view the symmetries of the color code which gives rise to its multitude of domain walls.
A DOCÊNCIA NA EDUCAÇÃO PROFISSIONAL: DA FORMAÇÃO POSTERGADA A UMA PRÁTICA PEDAGÓGICA “POLIVALENTE”
Authors: Mororó Leila Pio , Dos Santos Pereira Cláudio Wilson , Oliveira Anely Silva
Published: October 2018

Este texto discute a formação dos professores da Educação Profissional, buscando compreender sua relação com a prática pedagógica. Para tanto, parte de duas questões concretas: o perfil desses profissionais e as especificidades de suas atividades nas escolas profissionalizantes com destaque aos Institutos Federais de Educação, Ciência e Tecnologia – Institutos Federais. A respeito do perfil, destaca-se o fato de que os docentes que atuam nessa modalidade de ensino, muitas vezes, são profissionais liberais que adentram na escola técnica para ensinar uma determinada profissão, o que significa a inexistência da aquisição de uma formação pedagógica anterior para atuar na docência. Em relação às atividades que desenvolvem, quando se trata especificamente dos professores que atuam nos Institutos Federais, esses docentes, além da sala de aula, assumem atividades de pesquisa e de extensão, atuando também em níveis diferentes de ensino. A formação pedagógica prevista em lei para esses profissionais deixa a encargo das instituições promovê-la ou incentivá-la. Assim sendo, e dada as suas especificidades, nos Institutos Federais a formação está atrelada à titulação do corpo docente. Entretanto, por não terem a formação para a docência, muitos professores não interagem com as questões da escola. Conclui-se afirmando a necessidade de uma formação específica para os professores da Educação Profissional, principalmente para os que não tiveram a licenciatura na graduação, e a definição do perfil desses profissionais já no ingresso da carreira, enfatizando em ambos (a formação e o perfil) a noção do trabalho como princípio educativo.

O presente artigo analisa a produção do conhecimento acumulada no âmbito do banco de teses e dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), acerca da formação de professores para o atendimento às pessoas com deficiência. Tal estudo é produto de uma pesquisa realizada no mês de julho de 2017 no Portal da referida Coordenação, tendo sido utilizados os descritores: formação de professores para pessoas com deficiência, formação de professores para educação especial e formação de professores e educação especial, entre aspas duplas, os quais possibilitaram localizar 16 trabalhos que tratam da temática em análise. Entretanto, desse total, somente 09 estavam disponíveis para leitura. A inquietação pelo referido objeto de pesquisa partiu da constatação de que, ao longo dos anos cresceu o número de pessoas com deficiência adentrando nas instituições formativas e que estas, para garantir a efetivação da inclusão, foram impulsionadas a adotar novas posturas lançando as bases para novas perspectivas interventivas, que vão além da acessibilidade física e dizem respeito às adaptações e atualizações a que são chamados os professores que atuam com pessoas com deficiência.

Este artigo resulta de investigação que focaliza o Estágio como espaço de aprendizagem econstrução da identidade docente, em contexto de formação inicial, no Brasil e em Portugal. Oobjetivo foi analisar como estagiárias brasileiras e portuguesas entendem o componente do Estágio noprocesso de construção da sua identidade profissional. Para tanto foram delineadas algumas questões:Que elementos são destacados como relevantes pelos estagiários? De que maneira o Estágio contribuipara a construção da identidade docente? Como caminho metodológico optou-se pelo uso dasnarrativas recolhidas em relatórios e memoriais de formação, adotando-se assim uma abordagemqualitativa de análise. O suporte teórico é sustentado por referenciais da área da formação deprofessores, área multidisciplinar em que diferentes saberes se cruzam. Os dados revelaram que osmovimentos de construção identitária se acentuam no espaço/tempo do Estágio, destacando-se nasnarrativas que esse processo ocorre em diferentes contextos, e que a observação, a (auto)reflexão e asrelações estabelecidas nesse período são fundantes para o processo de tornar-se professor.
EDUCAÇÃO INTEGRAL EM ESCOLA PÚBLICA DE TEMPO INTEGRAL: PERCEPÇÕES DE ESTUDANTES

Published: October 2018

O objetivo deste artigo é ampliar as reflexões sobre educação integral de forma a contribuir para a compreensão – partindo do ponto de vista dos estudantes – das políticas educacionais voltadas para a ampliação da jornada escolar nas escolas públicas, analisando se estas têm corroborado para a efetivação da educação integral e emancipatória. Aqui estão sendo apresentados os resultados de uma pesquisa de iniciação científica desenvolvida no município de Santarém, estado do Pará, no ano de 2017. A metodologia compreendeu as seguintes fases: revisão de literatura; levantamento documental; observação na escola; aplicação de questionários aos estudantes. A escola pesquisada apresenta limitações em seus espaços, mesmo tendo sido planejada para o funcionamento em tempo integral. Buscou-se identificar e compreender pela percepção dos estudantes, o tempo mais prolongado que ficam na escola, as atividades/oficinas a eles ofertadas incluindo visitas externas. Fez-se uma pergunta mais abrangente sobre a escola propiciar-lhes educação integral. Os resultados revelam a importância de ouvir os estudantes, para que se sintam parte do processo, tornem-se comprometidos, participativos, curiosos, críticos. Concluímos que a proposta pedagógica da escola pesquisada pode ser enriquecida com a ampliação dos sujeitos da comunidade escolar na elaboração/revisão do projeto pedagógico uma vez que os problemas apontados são factíveis de solução e se trabalhados adequadamente, podem gerar importantes aprendizados tanto para os membros da escola quanto para as reflexões mais amplas em torno da educação integral.
TEORIA CRÍTICA E ESCLARECIMENTO: MEDIAÇÃO PARA UMA EDUCAÇÃO ESCOLAR EMANCIPATÓRIA
Authors: Maria Nobre Lopes Fátima , Lopes da Silva Filho Adauto
Published: October 2018

O processo de globalização do mundo contemporâneo afetou consideravelmente todos os setores da vida humana, inclusive a ciência, a tecnologia e a educação. Aqui se insere principalmente a educação escolar que, no caso do Brasil, atingiu certa universalização, embora a sua teleologia central esteja voltada mais para as demandas do mercado do que para a formação cultural e humana. A partir dessas considerações, este artigo objetiva dissertar sobre algumas concepções de Marcuse e de Adorno em torno da teoria crítica que poderão contribuir para o esclarecimento acerca da sociedade tecnológica e da barbárie que nela impera como condicionantes dos complexos sociais, dentre eles a educação escolar. Nesse sentido, a teoria crítica e, consequentemente, o esclarecimento poderão contribuir para a superação dessa dinâmica social instrumental tendo em vista uma educação escolar emancipatória.
The fractal nature approach in ceramics materials and discrete field simulation
Authors: Vuckovic Vladan , Mitic Vojislav , Kocic Ljubisa , Nikolic Vlastimir
Published: October 2018

In this paper, we present experimental data of static fractals and compare
the results with theoretical analysis obtained using dynamic particle
simulation. The fractal simulator presented in this manuscript is pioneer
work and it is the base of the future concrete and industrial applications.
We have examined sintered ceramic samples formed using several different
additives, as fabricated using various parameters, sintering temperature and
time. SEM analyses were performed on samples as a part of the experimental
characterization procedure. Based on microstructures, sets of points have
been selected as a primary database input for the theoretical-experimental
simulation to model the processes that describe the experiment. For all
grain and pore analyses, the fractal nature is recognized as a matter of
substantial influence on material characteristics. All of our experimental
and theoretical-experimental procedures are based on the construct that
reconstruction of the grain and pore fractal nature is of enormous
importance for microstructure property prognoses. The method presented here
can be used to simplify and simulate, in real time, the interaction of a few
thousand electrically charged particles possessing different masses through
formulations based on Maxwell?s electromagnetic equations. Particles in
simulation interact with alternating (or static) electromagnetic fields and
with static ceramics surface at the same time. All values are treated
numerically. The fractal simulator consists of two components, a structure
fractal generator, and field simulator. The functions for particle motion
can be implemented and changed within the program in real time. The
algorithm is written in the Delphi programming environment. The main result
of this paper describes a quite new approach in the analysis of material
microstructure properties towards programming-prognoses of the final
properties of ceramic materials using the fractal nature within the fractal
field simulator that generates structures, grains, and pores. The new
simulator algorithm is developed as the important tool for the realization
of the much ambitious project - simulation and realization of the Tesla?s
Fountain in ceramics. The concrete results will follow with this project
realization in near future.
Problematic pronominal anaphora
Authors: Jovanovic Radmila
Published: October 2018

In this paper I will analyse some problematic cases of pronominal anaphora,
such as the famous donkey-sentence: Every man who owns a donkey beats it.
The issue is to provide a satisfactory semantic analysis of pronouns ?he? or
?it?, which is challenging when the anaphoric pronoun in question depends on
an indefinite. I will compare solutions provided by dinamic semantics, such
as Discourse Representation Theory and Dinamic Predicate Logic, with new
solutions using Game Theorethical Semantics (GTS) and Constructive Tipe
Theory (CTT). I will scketch a dialogical account of anaphora, making use of
CTT. I will argue that the game theoretical approach, which puts emphasis on
expressing the dependence relations in terms of choices resulting from
interaction, is in fact the best way to deal with anaphora. Moreover, the
?outside-in? semantics seems to be much more promising in the analysis of a
natural language then the classical Tarskian ?inside-out? approach. However,
I will argue that the dialogical approach has the advantage over GTS because
it provides a clear first-order solution that does not require any devices
other than those of constructive or classical logic.
One example of formal coherence
Authors: Nedeljkovic Adam
Published: October 2018

The aim of this paper is to present one case of probabilistic formalization
of our intuitive notion of coherence. To that end, we will have to provide
answers for the questions, what are all relevant relations between beliefs,
as far as coherence is concerned, and of course, what is intuitive coherence.
After we settle those questions, we will try to show how, by applying certain
probabilsitic theories of confirmation to those relations, we can arrive at a
basic probabilistic theory of coherence. We will point out certain problems
of that theory. At the end of the paper, we will sum up the differences
between intuitive and probabilistic coherence, and we will try to provide
reasons why the successful formalization of this relation, should be a
desired result in epistemology.
The principle of deductive closure of knowledge and contextualism
Authors: Peric Marko
Published: October 2018

The hypotheses of radical skeptics are so conceived to put the attributor of
knowledge in such position that she can?t ascribe knowledge to anyone,
because the subject can?t get proper evidence to exclude skeptical
alternatives. There are several versions of the skeptical arguments by which
she tries to point out the impossibility of knowledge ascriptions as direct
consequence of the impossibility to rule out skeptical alternatives. All of
those arguments are based on a very intuitive epistemological principle: if
we know p, and if we know that p implies q, then we know q as well. This
principle is called the principle of deductive closure of knowledge (or
simply closure). In this paper, the author analyzes the most important
contextualist solutions to the skeptic paradox, those that accept the
closure principle, and those that reject it as well.
Apparatuses and counter-apparatuses (Agamben’s understanding of profanation)
Authors: Romcevic Branko
Published: October 2018

In this paper I am starting with Foucault?s notion of apparatus (dispositif),
showing its genealogy, its ?growth? from the concept of positivity (from
Archaeology of Knowledge), in order to demonstrate its double-sidedness: on
the one hand, functions of subjugation, and on the other, chance for
emancipation. Gilles Deleuze was the first to announce such adjustment of
that notion, identifying foucauldian apparatus as controling force, as well
as the one that can liberate human beings. Giorgio Agamben transposed that
division into the difference between sacred and profane, claiming that
apparatus works like the act of sacrifice, and that the opposing act of
profanation can be understood as the work of counter-apparatus. Following
Agamben?s analysis, language, in its poetic function (in its possibility of
enjambement), is the one of the most powerfull counter-appparatuses.
