Reshaping ‘time of limbo’ and ‘remoteness’: Everyday practices of reception of asylum seekers in Alpine municipalities in Italy
Authors: Giacomelli Elena , De Gregorio Orlando
Published: February 2022

This article focuses on the experiences of widespread reception of asylum seekers and refugees carried out in some Italian Alpine localities, specifically in Valsugana in Trentino and Val di Susa in Piemonte, in the west and in the east of northern Italy. We focus on the description of these two case studies and their relation with the frame of national policies on migration in Italy. What were the main characteristics of these two case studies? How do these local policies interact with the fragmentation, the inconsistency and the emergency-based approach of Italian national immigration policies? This research subsumes and aims to move beyond the questions raised above, focusing on the points of view and narratives of social workers, project managers and reception workers (operatore dell’accoglienza). These actors often describe the implementation process as a process of policy-making. In conclusion, these case studies highlight that in Italy good practices of reception represent a field where there are coordinations, tensions and conflicts between national and local levels. Indeed, in everyday practices, the limbo and isolation (characterizing the life of asylum seekers) are reshaped in inclusion paths. This daily process of policy-making is constantly at risk – in Italy, indeed, good practices of inclusion represent a battlefield criss-crossed by dilemmas.

A turizmuskutatás perifériáján – A hazai városnéző kisvonatok turisztikai szerepének és desztinációnkénti jellegzetességeinek vizsgálata térinformatikai (GIS) módszerekkel
Authors: Horváth Zoltán , Köbli Ádám , Morva Tamás
Published: February 2022

Kutatásunk az aktuális turizmusföldrajzi vizsgálatok köréből kiszoruló, ugyanakkor a frekventáltabb vá­rosi desztinációk kínálatában szinte mindenhol fellelhető és népszerű attrakció, a városnéző kisvonat turisztikai térben betöltött szerepét vizsgálja.

Jelen tanulmány egy nagyobb kutatási témakör része, amelyben a hagyományos, hosszú évtizedek óta a turisztikai kínálat részét képező, de a jelenkori, modern kutatási témák által kevésbé érintett és diva­tos területeket (városnéző kisvonatok, szuvenírek, utcai performance-ok – ’busking’) vizsgáljuk jelenlegi turisztikai súlyuk, megújulási lehetőségeik és a legújabb trendek függvényében. Áttekintjük a városnéző kisvonatok általános turisztikai jellemzőit, a termékcsoportok szerinti eltérő sajátosságaikat és komplex térinformatikai elemzéseket végzünk a kisvonatok útvonalai, megállóhelyei, a látnivalók és a szálláshelyek elhelyezkedésének összefüggésében. A turizmuskutatásban is egyre jelentősebb szerepet kapó GIS eszköz­készlet segítségével olyan összetett eredményeket kaphatunk, amelyek a különböző rétegek és eredményso­rok komplex értelmezését és megjelenítését teszik lehetővé.

Esettanulmányként három speciális és a hazai turisztikai piacon domináns termékcsoport egy-egy meghatározó turisztikai kereslettel rendelkező települését választottuk ki. A legtöbb turistát vonzó, ma­gas minőségű hazai egészségturizmus példájaként Sárváron; a balatoni, szezonálisan kiemelkedő vízparti turizmus esetében Keszthelyen; és a kulturális- és természeti értékekre épülő városi turizmus képviselője­ként Tata városában elemezzük a kisvonatok szerepét és a turisztikai kínálatra gyakorolt hatásait.
A közösségi média szerepe a fesztiválturizmusban – a Szegedi Ifjúsági Napok és a Green Future példáján
Authors: Süli Dorottya , Martyin-Csamangó Zita
Published: February 2022

A technológia fejlődése és az internet térnyerése új trendeket indított el a turizmusban is. A közösségi média használatának terjedésével az élmények online megosztása, keresése egyre népszerűbbé válik, mely egyrészt befolyásolhatja az utazási döntések meghozatalát, másrészt hozzájárulhat az adott desztináció imázsának javításához, ismertségének növeléséhez.

A fesztiválok, különösen a zenei fesztiválok évek óta egyre több – elsősorban fiatal – turistát vonzanak, akik túlnyomó többsége a közösségi hálózatokat használja élményei megosztására. Kutatásunk során a Szegedi Ifjúsági Napok és a Green Future fesztiválozói körében végeztünk kérdőíves felmérést, melyben a közösségi média fesztiválturizmusra gyakorolt hatása mellett vizsgáltuk, hogy a megkérdezettek hogyan ítélik meg a fesztiválok desztinációra gyakorolt hatásait. Ezek közül az imázserősítő hatás megjelenését több módszerrel is vizsgáltuk.

Az eredmények alapján megállapítható, hogy a megkérdezett fesztiválozók nagy jelentőséget tulajdonítanak élményeik megosztásának és jelentős arányban használják a közösségi médiát információk keresésére. Megállapítható az is, hogy a két könnyűzenei fesztivál hozzájárul a települések imázsának alakításához, hiszen mind a vizsgált bejegyzésekben, mind a válaszadók asszociációiban többször együtt jelentek meg.

BACKGROUND: In 2018, a Frestyle Libre flash glucose monitoring system (FGM) appeared in Russia and became a potential alternative to the traditional CGM. Studies carried out to date have shown the advantages of FGM over SMBG, but only a few of them relate to real clinical practice, especially in children with type 1 diabetes.OBJECTIVE: To evaluate the efficacy of FGM in children with T1DM in relation to glycemic control indicators, the occurrence of severe hypoglycemia and diabetic ketoacidosis, as well as the satisfaction of patients and their parents with the use of FGM.MATERIALS AND METHODS: Single-center, prospective, observational cohort study. Children 4–18 years old with T1DM and HbA1c level less than 10.0% were invited to participate in the study on intensified insulin therapy (by MDI or CSII). The duration of the patient’s participation in the study was 6 months. At baseline and every 3 months thereafter, face-to-face consultations were conducted with an assessment of the general condition, HbA1c study, an assessment of glycemic indicators, progress in relation to glycemic control targets and correction of the therapy. A total of 228 patients (110 boys and 118 girls) who met the inclusion criteria were included in the study. The median age was 11.2 (8.6–14.7) years, the duration of type 1 diabetes was 3.8 (2–7.1), 136 patients received insulin therapy by CSII for 1.3 (0.8–2.6) years.RESULTS: In the general group of patients, 3 and 6 months after the start of FGM use, the HbA1c values decreased statistically significantly by 0.2%. In addition, the number of children with HbA1c <7.5% increased by 6.1 and 4.9% at 3 and 6 months, respectively, but these changes were not statistically significant. The number of cases of DKA when using FGM decreased by 74%, and the number of cases of severe hypoglycemia by 83%, thus the number of episodes decreased by 4 and 6 times, respectively. Patients and / or their parents rated the ease of use and their experience with FGM on a scale from 0 (strongly agree) to 4 (strongly disagree). The majority of children and parents positively (0 or 1) assessed the convenience of installing and wearing the sensor (72.7–98.2%) using the FGM system in general (75.0–96.4%) and in comparison with the SMBG glucometer (92.3–98.2%).CONCLUSION: The installation and use of FGM is convenient and comfortable for the vast majority of children and parents, while compared to SMBG, the use of FGM is more convenient and simpler, and glucose measurement is much faster and less painful.

Authors: Sukhareva O. Y. , Zuraeva Z. T. , Shamhalova M. S.
Published: February 2022

The series of the cardiovascular outcome trails have demonstrated the nephroprotective properties of the gliflozins. Canagliflozin in the CREDENCE, which was the first study with a primary focus on the evaluation of the nephroprotective properties of gliflozin, have demonstrated the possibility to slow the progression of the renal disease. The paper summarizes the additional data from the CREDENCE trail: assessment of the efficacy of canagliflozin by initial eGFR; efficacy in individuals with GFR <30 ml/min/1.73 m2 ; long-term effects of canagliflozin on anaemia-related outcomes; effects of canagliflozin on serum potassium; effects on heart failure and cardiovascular mortality. There are discussed the current treatment algorithms for patients with type 2 diabetes and CKD where using of gliflozins is a priority option. Canagliflozin is a drug with a relatively low ratio of SGLT1/SGLT2 selectivity. The effects of the inhibition of SGLT1 transport in the kidney and in the intestine are described and their additional influence on reducing of the postprandial glycemia and additional nephroprotection.

Este artigo busca discutir e propor notas sobre a fotografia de Jeff Wall para perceber como características que excedem a poética dos artista podem contribuir para a compreensão de fotografia de quadro-vivo, enquanto uma manifestação que se estabelece a partir de imagens construídas através de encenações e que extrapola noções de realidade para flertar com a ficção. Assim, parte-se inicialmente de uma análise de discursos históricos sobre a fotografia e sua identificação como fonte de registro do real para notar também a sua libertação enquanto representação fiel do mundo.
discurso teatral nas fronteiras entre vida e arte
Authors: Gonçalves Jean Carlos , Teles de Souza Adriana
Published: February 2022

O objetivo do presente estudo é compreender o processo de construção/composição do discurso teatral em um programa de arte e cultura desenvolvido por um centro de artes em Curitiba – Paraná – Brasil. O mirante teórico é ancorado na concepção dialógica do discurso, tendo nos estudos de Bakhtin e o Círculo seu principal referente. As materialidades analisadas buscam as potencialidades do discurso teatral tanto por um trabalho com práticas corporais quanto pela escrita de textos teatrais. Buscou-se, a partir da análise das vivências com os estudantes, aproximar, nos processos artísticos de criação cênica, aspectos da vida e da arte, compreendendo-os como movimento discursivo, repletos de elementos de teatralidade e vinculados à esfera educacional. Os resultados permitem concluir que o trabalho com a construção/composição do discurso teatral em contextos de educação não tem como menosprezar as fronteiras entre vida e arte, já que ambas se interconstituem e se intercomplementam.
Teatro, tecnologias e educação em perceptos e afectos inovadores
Authors: Fusaro Márcia
Published: February 2022

Este artigo percorre algumas reflexões em nível epistemológico e empírico sobre o teatro, enquanto busca compreender melhor como estaria se dando, nesse basilar território da Arte, o emprego dos conceitos ligados ao teatro em interfaces com tecnologias criadoras de novos perceptos e afectos na arte contemporânea em diálogo com a educação. Interceptando-se o cenário da pandemia, iniciado em 2020, acrescenta-se, ainda, a urgência de maiores reflexões sobre a criação e a prática de novas linguagens. Isso porque, dentre outros expedientes proporcionados pelos mais recentes usos das novas tecnologias, passaram a fazer parte integrante do teatro e da educação também as redes sociais, as aulas e os eventos on-line, pensados nos contextos das interações não presenciais do período pandêmico. Gilles Deleuze e Antonin Artaud nos conduzem como pensadores referenciais, por entendermos ambos também como educadores, no sentido de haverem feito escola sobre a criação filosófica e artística voltada à Diferença e à Vida. Acrescente-se, ainda, o fato de que no novo cenário pandêmico, lido semioticamente, o corpo e a máscara têm sofrido des(re)territorializações, se vistas à luz dos conceitos deleuzeanos de “rostidade” e “corpo sem órgãos”, este último inspirado em Artaud.

Memórias Cartográficas
Authors: Carvalho Santos Núbia Agustinha
Published: February 2022

Estive atravessada por diferentes ritmos nos espaços escolar e museológico, em 2015 e 2016, acompanhando e vivendo os processos cartográficos de uma pesquisa realizada numa escola de Educação Infantil, na cidade de Fortaleza. Alguns autores foram como vagalumes nessa caminhada acadêmica, derramando centelha nos acontecimentos, fazendo-me enxergar múltiplas camadas. Dentre esses teóricos destaco Mikhail Bakhtin (1995), filósofo da linguagem, cujo pensamento alarga a reflexão produtora de sentidos a partir dos conceitos de dialogismo e heteroglossia. No que tange a cartografia, lancei mão dos estudos de Gilles Deleuze e Félix Guattari (2011), por pensar os processos de subjetivação de modo rizomático. O estudo teve como categoria central a mediação educativa, considerada como potencializadora de conhecimento artístico, cultural e sensível para todos os envolvidos no processo de formação. Tal mediação foi como um andaime na produção de sensibilidade, que acedeu à linguagem artística de crianças e adultos às obras de arte contemporânea.

Pengamanan Data Foto pada Perangkat OS Android Menggunakan Teknik Kriptografi Hill Cipher
Authors: Widodo Aris Puji , Sarwoko Eko Adi , Suharto Edy , Siahaan Josua Fredy Orlando
Published: February 2022

Perkembangan teknologi informasi yang semakin cepat perlu dibarengi dengan sistem pengamanan dalam pemanfaatanya. Salah satu diantaranya adalah keamanan data-data file foto (citra) yang di simpan pada perangkat mobile OS android. Perangkat mobile sangat berpotensi terjadi kehilangan akibat pencurian atau disalahgunakan oleh pihak lain yang tidak bertanggung jawab, sehingga informasi yang tersimpan didalamnya sangat beresiko untuk diketahui oleh pihak lain. Oleh karena itu, untuk mengurangi resiko terbukanya informasi data foto pribadi yang tersimpan di perangkat mobile, diperlukan sebuah upaya mekanisme pengamanan data foto tersebut. Mekanisme pengamanan yang dilakukan adalah dengan cara menyimpan data foto tersebut ke dalam format sandi dan jika ingin membuka kembali informasi aslinya perlu dilakukan dengan mengembalikan dari format sandi ke format semula (enkripsi dan dekripsi). Adapun format sandi file foto yang disimpan di perangkat OS android yang digunakan pada penelitian ini adalah menggunakan algoritma hill chiper. Algoritma hill chiper adalah suatu fungsi matematis yang digunakan untuk melakukan enkripsi dan dekripsi. Hill cipher yang merupakan poly alphabetic cipher dapat dikategorikan sebagai block cipher, karena file foto yang diproses akan dibagi menjadi sejumlah blok dengan ukuran tertentu. Hasil proses enkripsi dan dekripsi file foto yang dihasilkan pada penelitian ini, akan menghasilkan ukuran file foto yang lebih besar dibandingkan dengan file foto aslinya. Sedangkan tingkat keacakan informasi pada file foto yang dilakukan enkripsi sangat tergantung pada indek kunci yang digunakan. Semakin besar indeks kunci yang digunakan, maka akan semakin tinggi tingkat keacakan file foto hasil enkripsi yang dihasilkan.
Perbandingan Naïve Bayes Classifier dan Support Vector Machine untuk Klasifikasi Judul Artikel
Authors: Maarif Muhammad Rifqi
Published: February 2022

Support Vector Machine (SVM) dan Naïve Bayes Classifier (NBC) merupakan dua algoritma yang sangat polpuler untuk text mining, khususnya untuk klasifikasi teks. Pada penelitian-penelitian sebelumnya SVM cenerung menghasilkan performa yang lebih baik dari NBC pada segi akurasi hasil klasifikasi. Salah satu hal yang menarik dari penelitian-penelitian sebelumnya adalah penggunaan jenis data yang hamper sama antara satu dengan lainnya. Penelitian-penelitian sebelumnya kebanyakan menggunakan data tweet dari situs Twitter. Data tweet merupakan jenis teks yang informal dengan banyak sekali noise dan tidak mengindahkan aturan tata bahasa. Pada penelitian kali ini, akan algoritma SVM dan NBC akan diujicobakan kedalam data teks yang lebih formal, yakni data dari judul-judul artikel. Dalam percobaan yang sudah dilakukan, didapatkan hasil yang berbeda dengan penelitian sebelumnya. Pada klasifikasi teks judul artikel NBC memiliki performa akurasi yang lebih baik jika dibandingkan dengan SVM.

Objectives

Standard of care sepsis biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT) can be affected by several perinatal factors, among which perinatal asphyxia (PA) has a significant role. In this light, new early sepsis biomarkers such as presepsin (P-SEP) are needed to enact therapeutic strategies at a stage when clinical and laboratory patterns are still silent or unavailable. We aimed at investigating the potential effects of PA on longitudinal P-SEP urine levels.

Methods

We conducted an observational case-control study in 76 term infants, 38 with PA and 38 controls. Standard clinical, laboratory, radiological monitoring procedures and P-SEP urine measurement were performed at four time-points (first void, 24, 48, 96 h) after birth.

Results

Higher (p<0.05) CRP and PCT blood levels at T1–T3 were observed in PA than control infants whilst no differences (p>0.05, for all) at T0 were observed between groups. P-SEP urine levels were higher (p<0.05) in PA at first void and at 24 h while no differences (p>0.05) at 48 and 96 h were observed. No significant correlations were found (p>0.05) between P-SEP and urea (R=0.11) and creatinine (R=0.02) blood levels, respectively.

Conclusions

The present results, showed that PA effects on P-SEP were limited up to the first 24 h following birth in absence of any kidney function bias. Data open the way to further investigations aimed at validating P-SEP assessment in non-invasive biological fluids as a reliable tool for early EOS and LOS detection in high-risk infants.
An adjusted Grubbs' and generalized extreme studentized deviation
Authors: Alrawashdeh Mufda Jameel
Published: February 2022

Detecting outlier data is an interesting subject in the statistical field. Grubbs’ test is one of the common detection methods of outlier observation at univariate data sets. This approach is based on the mean and standard deviation of univariate data, and hence, these data are highly affected by the presence of outliers. An improvement for Grubbs’ test is proposed in this paper to increase the power of detecting data.

Published: February 2022

Three-dimensional investigation has been carried out to simulate buoyancy induced heat transfer and fluid flow as well as entropy creation inside C-shaped enclosure charged with based water CNT–Al2O3 (15–85%) hybrid nanofluid. Left side is isothermally heated while the vertical portions of the right wall are isothermally cooled. Effects of various parameters on the flow behavior and the produced irreversibilities, namely the cavity aspect ratio (0.1 ≤ Ar ≤ 0.4), Rayleigh number (103 ≤ Ra ≤ 106) and volumetric fraction of hybrid nanofluid (0 ≤ φ ≤ 0.06) have been examined. It was revealed that the aspect ratio is the main controlling parameter of thermal energy transfer and generated entropy. In addition, for specific Ra, adding hybrid nanoparticles leads to the increase of the average Nusselt number while the highest produced entropy is observed with higher Rayleigh number. Moreover, the maximum Bejan number occurred for a shape factor Ar = 0.1 and Ra = 104 disregarding the hybrid nanoparticles volume fraction showing the dominance of thermal irreversibility over the viscous dissipation irreversibility in such conditions.

This paper reviews recent advances in the research and development of graphene-based plasmonic metamaterials for terahertz (THz) laser transistors. The authors’ theoretical discovery on THz laser transistors in 2007 was realized as a distributed-feedback dual-gate graphene-channel field-effect transistor (DFB-DG-GFET) in 2018, demonstrating ∼0.1 µW single-mode emission at 5.2 THz and ∼80 µW amplified spontaneous 1–7.6 THz emission at 100 K. To realize room-temperature, dry-cell-battery operating intense THz lasing with fast direct modulation, various approaches based on graphene plasmonic metamaterials are investigated and introduced as real device implementations, including (i) replacement of the laser photonic cavity with plasmonic cavity enormously improving the THz photon field confinement with larger gain overlapping, (ii) introduction of THz amplification of stimulated emission via current-driven graphene Dirac plasmons (GDPs), and (iii) controlling the parity and time-reversal symmetry of GDPs enabling ultrafast direct gain-switch modulation. Possible real device structures and design constraints are discussed and addressed toward coherent light sources applicable to future 6G- and 7G-class THz wireless communication systems.
An ultra-compact angstrom-scale displacement sensor with large measurement range based on wavelength modulation
Authors: Xu Yi , Gao Baowei , He Axin , Zhang Tongzhou , Zhang Jiasen
Published: February 2022

Optical displacement metrology is important in nanotechnology and used to identify positions and displacements of nanodevices. Although several methods have been proposed, a sensor with ultracompact size, angstrom-scale resolution, and large measurement range is still lacking. We propose an optical displacement sensor with wavelength modulation that can demonstrate subwavelength footprint and angstrom-level resolution with large measurement range in this study. The proposed sensor consists of two optical slot antennas. Surface plasmon polaritons (SPPs) are launched at antennas and interfere when a tightly focused broadband light source illuminates the sensor. Spectrum of output SPPs presents a dip, which depends on the position of focal spot of incident light and is used to extract displacement. A maximum resolution of 0.734 nm was obtained. Furthermore, we used interference fringe of two broadband beams as light source and the measurement range of the sensor is not limited by the size of the tightly focused light source while maintaining high resolution. The method utilizes a new mechanism of wavelength modulation to overcome the trade-off between the high resolution and large measurement range, and achieve a variety of potential applications for nanometrology in the future.
Artificial Intelligence Policy Regimes: Comparing Politics and Policy to National Strategies for Artificial Intelligence
Authors: Filgueiras Fernando
Published: February 2022

Research on artificial intelligence policy is still at an early stage. Artificial intelligence policy is an emerging domain of technology policy that is twofold: firstly, research and deployment of AI technology and, secondly, the design of regulatory instruments that focus on the impacts of technology on society, the economy, and politics. This article presents the concept of artificial intelligence policy regimes for analysis of design and technology dominance strategies. A typology of artificial intelligence policy regimes is formulated by relating political regimes to governance modes to understand ideas, actors, and institutions that establish AI policy dynamics. This framework is applied to an analysis of six national strategies for artificial intelligence: those of the United States, Brazil, Saudi Arabia, China, Singapore, and Russia.

En el presente artículo, la autora analiza la situación del trabajo doméstico y del trabajo de cuidado no remunerado tomando en consideración los resultados de las encuestas de uso de tiempo llevadas a cabo en los países de la subregión andina y su contribución al PIB. Los estudios sobre el uso del tiempo aportan valiosa información sobre cómo las personas distribuyen su tiempo en el trabajo remunerado como no remunerado, demostrando que existe un reparto desigual entre mujeres y hombres. Las mujeres trabajan más horas que los hombres en Perú, Ecuador, Bolivia y Colombia donde existen datos disponibles, sea en la condición en la que se encuentren. Por otro lado, nos permite constatar la importancia del trabajo doméstico y del trabajo de cuidado no remunerado en la reproducción social.

Human Foreskin Fibroblasts (HFF-1) and L6 muscle cells were treated in several conditions to examine the proliferation and adhesion of cells using different extracellular matrix proteins with different concentrations. These proteins consist of Collagen & Fibronectin with concentrations of 5ug/ml and 10ug/ml respectfully. The experiment was conducted and focused on how HFF-1 and L6 cells proliferate in two different conditions over a 7-day period and the results were recorded on Days 1, 3 & 7 (n=9). Different concentrations of Fibronectin and Collagen altered the proliferation of HFF-1 cells over a 7-day period. Once it was identified that the best proliferation of HFF-1 and L6 was the Fibronectin 10ug/mL coating, we used the same protein matrix to study the effects of different concentrations of Generic Omega-3 in cell adhesion and proliferation. Throughout the study, it is observed that proliferation is not proportional to the Omega-3 concentration, meaning in this study 1 mg/ml had the lowest proliferation. In conclusion from the first study, higher concentrations of Generic Omega-3 decreases the proliferation of HFF-1 and L6 cells. This is a known characteristic as Omega-3 inhibits cell proliferation by prolonging the G1 phase but did not arrest the G0-to-G1 or G1-to-S transitions. The prolonged G1 phase in fad3b ESCs was probably induced by downregulation of Cdk4 expression via p21 upregulation. In comparison to the Generic product of Omega-3 we decided to incorporate the Synthetic substance of Omega-3 into the study. The overall goal of this experiment was to observe the proliferation and adhesion of HFF-1 and L6 cells in artificially created media containing pure Synthetic Omega-3 fatty acids. This experiment was repeated three times (n=9) to gain valuable conclusive data which could be used to design future experiments. An additional experiment was specifically designed to see how HFF-1 and L6 cells migrate through a thick 3-D layer of fibrin. Fibrin is a substance formed through catalytic conversion of coagulation constituents: fibrinogen and thrombin. This experiment was conducted, and the results were taken for Day 1 and Day 7. Our results remained consistent in comparison to prior studies. With the use of higher concentrations of Synthetic Omega-3 there was a decrease in proliferation for both HFF-1 and L6 cells.

Isu Jokowi anggota Partai Komunis Indonesia kembali muncul menjelang kontestasi pemilihan Presiden 2019. Isu ini menyebar setelah beredarnya foto di media sosial yang  menampilkan Jokowi berada di podium bersama Ketua PKI D.N. Aidit yang sedang berpidato pada 1955. Terkait isu tersebut, Jokowi gencar melakukan klarifikasi di berbagai kesempatan, dan Tempo.co termasuk media online yang aktif memberitakan klarifikasi isu terkait Jokowi PKI. Artikel ini menjelaskan bagaimana Tempo.co membingkai pemberitaan klarifikasi isu Jokowi PKI. Penelitian ini menggunakan analisis framing Zhongdang Pan dan Gerald M. Kosicki. Model framing menggunakan empat unsur dalam membedah teks yaitu, sintaksis, skrip, tematik, dan retoris. Hasil penelitian ini menunjukkan bahwa pada pemberitaan klarifikasi isu Jokowi Partai Komunis Indonesia, Tempo.co mencoba “menggiring” opini publik agar sependapat dengan Tempo.co yang juga sepenuhnya sependapat dengan Jokowi.

El goalball es un deporte paralímpico colectivo con características de oposición, pero sin invasión por parte de los atletas que, a pesar de requerir gran condición física en las acciones ofensivas y defensivas, también se identifica como un deporte táctico, en donde la administración de la técnica en las diversas situaciones del juego determina el éxito en la competencia. El objetivo del estudio fue analizar la efectividad del ataque de la Liga Nacional de goalball de Chile, según tipo de lanzamiento y trayectoria. Se filmaron cuatro partidos de goalball de la fase final de un torneo nacional. Para ello, se utilizó una cámara digital posicionada detrás de un arco ubicado en altura. Para el análisis de los partidos se utilizaron los diagramas propuestos por Morato et al. (2016) y Morato (2012). Los datos se transcribieron de forma computacional a una planilla, para luego ser analizados descriptivamente. El lanzamiento frontal (FRO) fue el que más se utilizó (88.9%), con una tasa de efectividad del 6.2%. Se realizaron trayectorias más largas en diagonales cortas (DC) y paralelas (PA) (31.3% y 23.2%, respectivamente). El lanzamiento de FRO se dirigió en DC (34.5%) y PA (22.4%), mientras que, por otro lado, los lanzamientos con giro (GIR) se dirigieron preferentemente en PA (30.4%) y DC (29.1%). El lanzamiento FRO fue más efectivo en PA (10.6%), mientras que el lanzamiento GIR fue más efectivo en diagonales medias (DM) (12.5%). Las posiciones laterales ejecutan lanzamientos, preferentemente FRO; pero en defensa, las posiciones centrales son protagonistas. Los lanzamientos son más efectivos cuando se dirigen en PA y DC.
