Kecemasan merupakan salah satu masalah psikologis yang banyak
dijumpai dan merupakan suatu yang tidak asing lagi dalam kehidupan mahasiswa,
karena kecemasan merupakan pengalaman universal yang dialami oleh siapa saja,
kapan saja dan di mana saja. Mahasiswa juga tidak terlepas dari kecemasan dalam
beraktivitas. Penyebab kecemasan mahasiswa tingkat akhir dapat berasal dari
kehidupan akademiknya, terutama dari kebutuhan eksternal dan harapan mereka
sendiri. Dan Dzikir lisani ini membantu individu fokus pada ketegangan yang
dirasakannya, dan juga dzikir lisani ini dapat meredakan ketegangan emosi.
Kalimat dzikir yang diucapkan dengan tujuan sebagai proses pembelajaran yang
menumbuhkan jiwa kegigihan dan keikhlasan untuk mendapatkan cinta Allah

A implementação do PROEJA no CEFET-SC: relações entre seus objetivos, os alunos e o currículo de matemática
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Educação. Programa de Pós-graduação em Educação Científica e TecnológicaEsta pesquisa aborda as relações que se estabelecem entre os objetivos do Programa Nacional de Integração da Educação Profissional com a Educação Básica na Modalidade de Educação de Jovens e Adultos - PROEJA, as expectativas, as necessidades e os desejos dos alunos e os conhecimentos específicos do Currículo de Matemática deste Programa. O estudo foi realizado no contexto do PROEJA do Centro Federal de Educação Tecnológica de Santa Catarina - CEFET-SC, da Unidade de Florianópolis. Analisa-se o possível descompasso entre o Currículo de Matemática do PROEJA e os objetivos desse Programa em relação às expectativas, às necessidades e os desejos dos estudantes do referido Programa. Utiliza-se como referência metodológica a abordagem qualitativa, mediante os seguintes recursos: análise documental, estudo bibliográfico, aplicação de questionários e realização de entrevistas. O método de pesquisa delimita-se ao Estudo de Caso, tratando-se da questão do atual currículo de Matemática do referido programa. Busca-se, nos referenciais teóricos, o aprofundamento dos processos da Educação de Jovens e Adultos, o fracasso escolar e a relação com o saber; as orientações sobre elementos constitutivos de um currículo e; a compreensão das contribuições na Educação Matemática para EJA. Ao concluir, constata-se que o desejo dos alunos consiste no prosseguimento dos estudos depois de concluírem o PROEJA, na expectativa de buscar no CEFET-SC a chance "única" de conseguirem uma certificação profissional. No entanto, os educandos têm suas expectativas contrariadas ao perceberem que existe um descompasso entre os objetivos do PROEJA e o Currículo de Matemática, uma vez que ele está muito aquém daquilo que realmente desejam e necessitam. Assim, a partir da escuta e do diálogo estabelecido com os educandos neste trabalho, aponta-se na perspectiva de um currículo integrado para esse Programa, de modo que, de fato se concretize um novo paradigma no campo da EJA
Directional Filters for Cartoon + Texture Image Decomposition
No full textWe present in this article a detailed analysis and implementation of the cartoon+texture decomposition algorithm proposed in [A. Buades, J.L. Lisani, 'Directional filters for color cartoon + texture image and video decomposition', Journal of Mathematical Imaging and Vision, 2015]. This method follows the approach proposed by [A. Buades, T. Le, J-M. Morel, L. Vese, 'Cartoon+Texture Image Decomposition', IPOL 2011], based on low/high-pass filtering, but replaces the isotropic filters by a bank of low-pass directional filters. The cartoon image is obtained by filtering in the direction that leads to the largest local total variation rate reduction. This permits to improve the performance of the decomposition near image discontinuities, where an halo effect was produced by the previous method
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Preparation and characterization of lithium and sodium doped polymethyl methacrylate based gel polymer electrolytes for battery applications / Lisani Othman
No full textIn the present study, two systems of gel polymer electrolyte (GPE) samples composed of poly(methyl methacrylate) (PMMA) as a host polymer dissolved in a binary mixture of ethylene carbonate (EC) and propylene carbonate (PC) organic plasticizing solvents complexed with lithium triflate (LiCF3SO3) and sodium triflate (NaCF3SO3) as doping salts have been prepared by solution casting technique. These systems are the (PMMA– EC – PC – LiCF3SO3) system and the (PMMA – EC – PC – NaCF3SO3) system. The PMMA sample and the unsalted GPE sample (PMMA – EC – PC) have been prepared as a reference. The conductivity of the samples from each system is characterized by impedance spectroscopy. The room temperature conductivity for the highest conducting sample in the PMMA– EC – PC – LiCF3SO3 and PMMA – EC – PC – NaCF3SO3 systems is (2.56 ± 0.41) × 10-3 S cm-1 and (3.10 ± 0.63) × 10-3 S cm-1 respectively. The temperature dependence of conductivity for the GPE samples in both systems from 303 K to 373 K obeys the Arrhenius rule. The activation energy, Ea values have been calculated to be 0.19 eV and 0.18 eV for the highest conducting sample containing lithium salt and sodium salt respectively. The ionic and cationic transference numbers have been evaluated by DC and combined AC and DC polarization techniques to determine the charge carrier species within the GPE samples. Linear sweep voltammetry (LSV) and Cyclic Voltammetry (CV) techniques are performed in order to evaluate the electrochemical stability and properties of the prepared GPE samples. The highest conducting sample from PMMA – EC – PC - LiCF3SO3 and PMMA – EC – PC - NaCF3SO3 systems is found to be electrochemically stable up to 3.3 V and 3.4 V respectively. Fourier Transform Infrared (FTIR) and Raman spectra studies have proven that the salts, LiCF3SO3 and NaCF3SO3 along with plasticizing solvents EC and PC have formed complexes with the PMMA polymer. X-ray diffraction (XRD) reveals that the sample with the highest conductivityvalue at room temperature from each system has an amorphous phase. Field Emission Scanning Electron Microscopy (FESEM) study shows the morphology of these samples. Thermal studies indicate that the PMMA-based polymer electrolytes are stable up to 150 °C and from the glass transition temperature, Tg studies, the enhancement of amorphous region is confirmed. The performance of the cell fabricated employing the highest conducting sample from each system is examined. The cell that has been assembled using the configuration Li |GPE| LiMn2O4 for the GPE sample containing LiCF3SO3 salt and Na |GPE| MnO2 for the GPE sample containing NaCF3SO3 salt exhibits the first discharge capacity of 117 mAh g-1 and 162 mAh g-1 respectively
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
