Probijanje »četvrtog zida« kao interaktivni postupak suvremenog umjetničkog stvaralaštva
Authors: Huzjak Miroslav
Published: September 2020

Suvremena umjetnost izgubila je svoju likovnost, a ostala joj je samo vizualnost. S druge strane, prijelaz od likovne moderne ka nelikovnoj suvremenoj umjetnosti donio je i mnogo novosti; jedna od njih je tzv. ‘probijanje četvrtog zida’. Radi se o kazališnom (a zatim i filmskom) terminu koji označava trenutak kada se gledatelj na neki način interaktivno uključuje u predstavu, a likovi pokazuju svijest da su likovi u predstavi. Upravo će suvremena umjetnost istraživati postupke brisanja granica između umjetničkog i svakodnevnog čina, sugerirajući kako »sve je umjetnost« i »svaki čovjek je umjetnik«. Novo je doba donijelo otuđenost javnosti od znanosti i umjetnosti, ali i nova filozofska tumačenja medijskog krajolika i hiperrealnosti postmoderne. Hiperrealne postaju i digitalne igre, od kojih se neke temelje upravo na rušenju »četvrtog zida«. Zbunjene reakcije na tehniku rušenja »četvrtog zida« variraju u rasponu od verbalnih reakcija na performance, preko previše doslovnog shvaćanja filmova pa sve do tragičnih nesreća, čak i samoubojstava povezanih s određenim digitalnim igrama. To da stvarnost oponaša hiperstvarnost postalo je uobičajeno, ali otvorilo se i pitanje: može li suvremeni pojedinac s time izaći na kraj?
Exploring the Association of the Built Environment, Accessibility and Commuting Frequency with the Travel Times of High-Speed Rail Commuters: Evidence from China
Authors: Chung Hyungchul , Yang Yueming , Chen Chia-Lin , Vickerman Roger
Published: September 2020

This paper explores door-to-door commuting pa erns and the way commuting time is associated with three factors: the built environment, transport mode (from residence and workplace to HSR stations), and commute frequency. Econometric and statistical analyses are employed to examine evidence
from China that draws on a survey targeting Suzhou-based HSR commuters who travel to work in Shanghai. The findings present three major points. First, a dense urban environment around residence and workplace is associated with reduced commuting time to high-density healthcare facilities (Suzhou
and Shanghai) and financial institutions (Shanghai only). However, the density of public transport facilities near both residence and workplace has no association with commuting time. Second, taking the metro to and from HSR stations shows signi ficant association with increased commuting
time for the first and last miles, while walking from HSR stations to the workplace shows signi ficant reduction of commuting time. Third, daily commuting is associated with reduced commuting time in the first mile, while weekly commuting is reversely related to longer commuting time in the
last mile, which is coupled with a shorter commuting time for the first mile than the last mile. These findings lead us to conclude that reducing the total commuting time for a door-to-door journey is a key factor in associated commuting pa erns, commuting frequency, and travel mode choice.
This re flects the choices commuters make in relation to where they live rather than where they work, which off ers fewer options. A longer last mile relates to a weekly commuting pa ern rather than a daily commuting. The current public metro systems in both home and work cities appear to
be lengthy and inefficient. Transitoriented and integrated development is required to provide more efficient experiences for commuters.
High Speed Rail in Northern England Tactics and Policies for Implementing Mega Plans by Modular Incrementalism
Authors: Wray Ian , Thrower David , Steer Jim
Published: September 2020

Britain lags behind many other countries in its provision of high-speed rail. This paper looks in depth at the challenges of providing high-speed rail links, east–west, across Northern England, identi fied as a key issue by former Chancellor of the Exchequer George Osborne in
his Northern Powerhouse speech in 2014. We ask what can be learned from the politics of Britain's successful motorway programme in the 1960s and 1970s, and from the plan advanced for High Speed North by the late Professor Sir Peter Hall and colleagues, published some weeks before Osborne's
speech. Introducing the concept of centripetal urban dynamics, we doubt whether the suppression of public transport demand by the Covid 19 virus will be long lasting. Thus the Hall Plan still has remarkable relevance, especially in its tactics for sequencing investment, which we term modular
incrementalism. Some updating is needed, so that the investment strategy focuses on super critical problems for rail investment. We conclude with recommendations for the High Speed North project itself and re flect on wider implications for decision-making processes.

Preguntas educativas para la tecnología digital como respuesta
Authors: Suárez-Guerrero Cristóbal , Rivera-Vargas Pablo , Rebour Martín
Published: September 2020

El desarrollo educativo con tecnología digital no solo admite sofisticados artefactos tecnológicos, sino también inexorables preguntas. Este trabajo tiene como objetivo explorar de forma interrogativa la relación entre educación y tecnología digital a través de la caracterización de una serie de ámbitos y preguntas que exigen rutas de reflexión, trabajo e investigación más allá de la pregunta por el material didáctico en la educación. Se inscribe en la reflexión pedagógica y busca aportar elementos que permitan identificar futuros itinerarios, paradojas o problemas de investigación. El procedimiento metodológico, de corte cualitativo, fue el codiseño participativo en tres fases no secuenciales de trabajo: descubrimiento, ideación y prototipado. Como resultados se presentan 5 ámbitos: epistemológico, finalidad, contenidos, didáctica y evaluación. La construcción de significado educativo de la tecnología implica atender estos núcleos problemáticos de representación pedagógica para pensar la tecnología con todo su potencial, pero también con todos sus dilemas. Más que cerrar el foco analítico, aquí se busca abrir espacios reflexivos para encarar el reto de la legitimación del desarrollo educativo de la tecnología.

The Effect of Hybrid Fibers Reinforcement on the Mechanical and Physical Properties of Concrete
Authors: Khayoun Zaher I. , Kamal Hamza M. , Ibrahim Yasir K.
Published: September 2020

Background:

Hybrid fiber reinforced concrete is the use of two or more than two fiber textures in a single concrete matrix to improve the overall properties of concrete.

Materials and Methods:

In this study, the ductility of medium strength concrete was observed to improve by incorporating steel and polypropylene in a ratio of 50:50 as a hybrid fiber. Four proportions of Volume fractions (Vf) were used (0.25, 0.5, 0.75, 1%). The changes in the mechanical properties and density occurred due to the addition of these hybrid fibers.

Results:

The features examined include bulk density, compressive strength, and flexural strength by using thirteen concrete mixtures with various volume fractions of steel and polypropylene fibers.

Discussion:

The results showed a significant increase in compressive and flexural strength due to the addition of steel fibers. On the other hand, polypropylene fibers exhibited minor changes in the mechanical properties of hardened concrete exclusively in the mixtures made with both steel and polypropylene fibers in which the strength increased in comparison to plain concrete by 4.4% and to steel fiber group having the optimal strength and other properties.

Conclusion:

These remarks provide a clear view of the importance of using different fiber reinforcing systems to improve the mechanical performance of concrete, which is considered quasi-brittle.

Published: September 2020

Introduction: Serious health problems and poor health habits persist among adolescents despite access to health information and medical care. The study aimed to determine the status of access to health services, the need for health information, and the preferred source of information among adolescents in Turkey. Method: In this descriptive study, a questionnaire developed by the researchers was applied online to individuals aged 18-25 between September - December 2017. Descriptive statistics were shown with numbers (n) and percentages (%) or mean (m) and standard deviation (± SD). Pearson chi-square and Kruskal Wallis tests were used for data analysis. Results: The mean age of the total 1807 participants was 20.28 (±1.89) and 57% were female. The rate of adolescents whose number of visits to the family physician was accurate to national guidelines was higher among those who had attended public schools and who lived in a nuclear family. This rate was lower among those who continued high school in the lower developed part of Turkey. Only 12% of the adolescents had undergone a full physical examination and few were questioned about psychosocial aspects. The demand for counseling on health topics about risky behaviors differed according to gender. While school was the main ‘past’ source for information, the family physician was the most ‘preferred’ one. Conclusion: Missed opportunities exist in adolescent health. Adolescent health services should be maintained in a multidisciplinary manner. Especially primary care services and school settings should be strengthened to provide accurate health information to young people.
LIBERDADE DE EXPRESSÃO E SEUS LIMITES NUMA DEMOCRACIA: o caso das assim chamadas “fake news” nas redes sociais em período eleitoral no Brasil
Authors: Sarlet Ingo Wolfgang , Siqueira Andressa de Bittencourt
Published: September 2020

O recurso às redes sociais e seus instrumentos de comunicação e compartilhamento cada vez mais sofisticados e eficazes, tem ganhado – em relativamente pouco tempo – um espaço imenso no campo dos embates político-eleitorais, seja como via direta (oficial) da publicidade eleitoral, seja de modo indireto. Nesse contexto, como se verificou de modo particularmente agudo nas últimas eleições presidenciais nos EUA e no Brasil, o uso das assim chamadas fake news (mas também, entre outros, do discurso do ódio), igualmente dominou o cenário nos mais diferenciados meios de comunicação, com destaque, novamente, para o ambiente das redes sociais na internet. Nesse meio tempo, muito se pesquisou e escreveu sobre tais fenômenos, seja na perspectiva da ciência política, seja sob o ângulo da sociologia, psicologia, antropologia, neurociências, teoria da cultura, dentre outros. No caso do Direito, mais especificamente pela ótica do direito constitucional, um dos problemas centrais com o qual se tem ocupado a academia jurídica, mas também os órgãos estatais (designadamente, os poderes Legislativo, Executivo e Judiciário), é o de verificar em que medida o uso de técnicas de desinformação e o manejo das fake news, de modo especial, tem influenciado o pleno funcionamento da Democracia e de suas instituições, como é o caso, das eleições e do respectivo processo, centrais para uma democracia representativa e partidária. Nessa linha, o presente artigo pretende examinar, discutir e avaliar se – e em que medida – o uso de notícias falsas, falaciosas, descontextualizadas, imprecisas etc., aquilo que se tem designado genericamente de fake news, é protegido pelas liberdades de expressão e de informação e, se for o caso, quais os limites que podem ser legitimamente impostos em momentos de pleito eleitoral, de modo a não configurar um impacto desproporcional sobre o princípio democrático e o efetivo funcionamento das respectivas instituições. Outrossim, pretende-se confirmar a tese, já conhecida, não apenas da imprecisão terminológica, mas também do flagrante reducionismo da figura das fake news para dar conta da complexidade e alcance do fenômeno. Além disso – e esse o objetivo principal – o que se busca é examinar e avaliar, à luz do caso do Brasil e do respectivo marco normativo jurídico-constitucional, mediante recurso ao exemplo da propaganda eleitoral e de sua regulação, como se tem lidado com o uso da desinformação e fake news, quais são os desafios pendentes e em que consistem as possibilidades de equacionamento satisfatório do problema, preservando tanto a liberdade de expressão, quanto o funcionamento das instituições democráticas.

Authors: TÜRKTEN Nazlı , UYGUNER DEMİREL Ceyda Senem
Published: September 2020

Humic acids represent a major fraction of natural organic matter (NOM) in aquatic environments. Having undefined composition and complex ill-defined structures, their presence in natural waters is undesirable. In this study, solar photocatalytic activity of synthesized Fe-doped TiO2 photocatalysts was investigated for the degradation of a 100 kDa molecular size fraction of humic acid. For this purpose, catalysts comprised of 5 different molar ratios of Fe/Ti were prepared by in-situ sol gel method and characterized by FTIR and Raman spectroscopy. Optimum loadings of the catalysts were determined and the kinetics of humic acid removal was investigated focusing on UV–vis spectroscopic parameters. Moreover, fluorescence techniques such as excitation-emission matrix (EEM) were also acquired for elucidating induced structural changes of humic acid during photocatalytic degradation. Results revealed that, using photocatalysts prepared by in-situ sol-gel method 20 to 25% removal of humic acid could be attained after photocatalytic treatment of 120 min.
A HOME APPLIANCE CONTROL SYSTEM FOR ENERGY MANAGEMENT
Authors: APAYDIN ÖZKAN Hanife
Published: September 2020

In this work, a Home Appliance Control System is proposed as a Home Energy Management System for preventing high peak demand and reducing electricity cost while keeping user comfort. The proposed Home Appliance Control System consists of a home equipped with smart appliances, grid, communication network and a Main Controller and it is based on appliance interference under certain conditions. Appliances are separated as controllable, semi-controllable and uncontrollable according to their effects on user comfort. Main Controller is not allowed to interfere with uncontrollable appliances, but with semi-controllable and controllable appliances as much as it is permitted. Appliance interference is done on real time in the order of appliance priority defined by the user due to expected power consumption and the grid limit. The corresponding control algorithm of Home Appliance Control System is also developed. Simulation results demonstrate the effectiveness of the proposed system on achieving the intended goals.

Authors: ÇAKIL Turan , CARLAK Hamza , ÖZEN Şükrü
Published: September 2020

Bu çalışmada ses dalgalarının farklı ortam yüzeylerinde meydana getirdiği basınç ve hız değişimleri ele alınmıştır. Ultrason dalgalarına benzerliği nedeniyle çalışmada ses dalgaları kullanılmıştır. Dalga modeli olarak, gauss nabız dalga modeli kullanılmıştır. Ortam yüzeyleri olarak hava, su, metal, s-oil, polietilen gibi cansız yüzeyler, doku türleri da olarak bağ doku ve kas dokusu yüzeyleri analizlerde kullanılmıştır. Seçilen bu ortam yüzeylerinde, akustik dalgalarının oluşturduğu basınç etkileri, zamanda sonlu farklar (FDTD) metodu kullanılarak incelenmiştir. Örneklenen gauss ses dalgasının analizinde, iterasyon sayısı arttıkça yayılım değeri de artmaktadır. Polietilen yapılı katmanlarda ise sesin oluşturduğu basıncın etkisinin düşük olduğu (Pplastik=39,5 µPa ve Vplastik=13,17 µm/sn ) tespit edilmiştir. Canlı dokulardan bağ dokusu ve kas dokusu üzerinde yapılan incelemede ise bir ses dalgasının bu iki doku üzerinde benzer basınç (Pbağ=1,295 Pa, Pkas=1,282 Pa) ve hız (Vbağ=0,63 µm/sn, Vkas= 0,58 µm/sn) değerleri oluşturduğu gözlenmektedir.

Authors: Lu Lin , Zhang Jiayao , Xie Yi , Gao Fei , Xu Song , Wu Xinghuo , Ye Zhewei
Published: September 2020

Background

With the rise of mobile medicine, the development of new technologies such as smart sensing, and the popularization of personalized health concepts, the field of smart wearable devices has developed rapidly in recent years. Among them, medical wearable devices have become one of the most promising fields. These intelligent devices not only assist people in pursuing a healthier lifestyle but also provide a constant stream of health care data for disease diagnosis and treatment by actively recording physiological parameters and tracking metabolic status. Therefore, wearable medical devices have the potential to become a mainstay of the future mobile medical market.

Objective

Although previous reviews have discussed consumer trends in wearable electronics and the application of wearable technology in recreational and sporting activities, data on broad clinical usefulness are lacking. We aimed to review the current application of wearable devices in health care while highlighting shortcomings for further research. In addition to daily health and safety monitoring, the focus of our work was mainly on the use of wearable devices in clinical practice.

Methods

We conducted a narrative review of the use of wearable devices in health care settings by searching papers in PubMed, EMBASE, Scopus, and the Cochrane Library published since October 2015. Potentially relevant papers were then compared to determine their relevance and reviewed independently for inclusion.

Results

A total of 82 relevant papers drawn from 960 papers on the subject of wearable devices in health care settings were qualitatively analyzed, and the information was synthesized. Our review shows that the wearable medical devices developed so far have been designed for use on all parts of the human body, including the head, limbs, and torso. These devices can be classified into 4 application areas: (1) health and safety monitoring, (2) chronic disease management, (3) disease diagnosis and treatment, and (4) rehabilitation. However, the wearable medical device industry currently faces several important limitations that prevent further use of wearable technology in medical practice, such as difficulties in achieving user-friendly solutions, security and privacy concerns, the lack of industry standards, and various technical bottlenecks.

Conclusions

We predict that with the development of science and technology and the popularization of personalized health concepts, wearable devices will play a greater role in the field of health care and become better integrated into people’s daily lives. However, more research is needed to explore further applications of wearable devices in the medical field. We hope that this review can provide a useful reference for the development of wearable medical devices.

Published: September 2020

AbstrakSungai Klampok mengalir melalui Kecamatan Bergas dan sekelilingnya terdapat beberapa industri sehingga mengakibatkan sungai tersebut tercemar karena menjadi badan penerima air limbah. Akibat penurunan kualitas air Sungai Klampok akan berimbas pada penurunan kualitas air tanah yang digunakan oleh penduduk sekitar sungai tersebut. Penelitian ini bertujuan untuk mengetahui kualitas air tanah yang berada di sekitar Sungai Klampok sebagai akibat adanya pengaruh beban pencemaran oleh air limbah industri berdasarkan Permenkes No. 416/MENKES/PER/IX/1990 tentang persyaratan kualitas air bersih. Lokasi pengambilan sampel air sungai dibagi menjadi 3 stasiun (LK1, LK2 dan LK3) sedangkan untuk sampel airtanah dari rumah-rumah penduduk dilakukan pada 6 titik yaitu 3 titik di daerah utara dari Sungai Klampok (U1,U2, U3) dan 3 titik di daerah selatan dari Sungai Klampok (S1,S2, S3). Pengambilan sampel dilakukan pada musim kemarau. Dari hasil uji kualitas air sungai, pencemaran yang terjadi pada air sungai Klampok masuk dalam kategori tercemar ringan-sedang. Sedangkan hasil uji kualitas air tanah masih berada di bawah baku mutu yang disyaratkan oleh Permenkes No. 416/MENKES/PER/IX/1990, sehingga penurunan kualitas air sungai Klampok tidak mempengaruhi kualitas air tanah di sekitar sungai tersebut. AbstractThe Klampok River flows through the Bergas Subdistrict and there are a number of industries around it, causing the river to become polluted because it becomes the body of the recipient of wastewater. As a result of the decline in the quality of the water in the Klampok River, it will impact on the quality of groundwater used by residents around the river. This study aims to determine the quality of groundwater around the Klampok River as a result of the influence of pollution load by industrial wastewater based on Permenkes No. 416 / MENKES / PER / IX / 1990 concerning requirements for clean water quality. The location of river water sampling is divided into 3 stations (LK1, LK2, and LK3) while for groundwater samples from residential houses is carried out at 6 points, namely 3 points in the northern area of Klampok River (U1, U2, U3) and 3 points in the area south of the Klampok River (S1, S2, S3). Sampling is done in the dry season. From the results of the test of river water quality, pollution that occurs in Klampok river water is categorized as mild-moderate polluted. While the results of groundwater quality testing are still below the quality standards required by Permenkes No. 416 / MENKES / PER / IX / 1990 so that the decline in the water quality of the Klampok river does not affect the quality of groundwater around the river.

Published: September 2020

Kabupaten Serang membutuhkan peta bahaya, peta kerentanan dan peta risiko bencana tanah longsor sebagai dasar dalam pengurangan risiko. Parameter dan bobot untuk pembuatan peta bahaya longsor adalah: kelerengan (50%), kondisi geologi (20%), curah hujan (15%) dan penggunaan lahan (15%). Zona bahaya tanah longsor tinggi di Kabupaten Serang terdapat di kecamatan-kecamatan Padarincang, Ciomas, Mancak, Anyar, Cinangka, Pulo Ampel dan Bojonegara. Pembuatan peta kerentanan digunakan kerentanan sosial dengan indikatornya adalah: kepadatan penduduk, rasio jenis kelamin, rasio kemiskinan, rasio orang cacat dan rasio kelompok umur. Peta risiko tanah longsor dibuat dengan mengoverlaykan dari peta bahaya tanah longsor dan peta kerentanan. Pembuatan peta bahaya, peta kerentanan dan peta risiko mengunakan teknik overlay atau tumpang tindih dengan software ArcGIS. Daerah berisiko rendah di Kabupaten Serang seluas 92.416 ha (63,6% dari seluruh luas Kabupaten Serang), berisiko sedang seluas 46.971 ha. (32,3%) dan yang berisiko tinggi 5.907 ha. (4,1%). Bila dilihat dari tingkatan kecamatan, 5 urutan teratas kecamatan yang memiliki luasan daerah berisiko tinggi terbesar adalah Kecamatan Anyar (1.498 ha), Pulo Ampel (1,082 ha), Bojonegara (1.019 ha), Baros (828,5 ha) dan Padarincang (561 ha). Peta bahaya, peta kerentanan dan peta risiko sangat dibutuhkan oleh Pemerintah Kabupaten Serang, selain sebagai acuan kegiatan pengurangan risiko bencana juga untuk penataan kawasan yang aman berkelanjutan. Serang District requires hazard maps, vulnerability maps and risk maps as a basis for reducing the risk of landslides. Parameters and weights for making landslide hazard maps are: slope (50%), geological conditions (20%), rainfall (15%) and land use (15%). High landslide hazard zones in Serang District are found in the sub-districts of Padarincang, Ciomas, Mancak, Anyar, Cinangka, Pulo Ampel and Bojonegara. Making a vulnerability map used social vulnerability with indicators: population density, sex ratio, poverty ratio, ratio of disabled people and ratio of age groups. Landslide risk maps are made by overlaying landslide hazard maps and vulnerability maps. Making hazard maps, vulnerability maps and risk maps using overlay techniques with ArcGIS software. Low-risk areas in Serang District covering 92,416 ha (63.6% of the total area of Serang Regency), medium risk of 46,971 ha. (32.3%) and high risk 5,907 ha. (4.1%). When viewed from the sub-district level, the top 5 sub-districts that have the largest high-risk areas are Anyar District (1,498 ha), Pulo Ampel (1,082 ha), Bojonegara (1,019 ha), Baros (828.5 ha) and Padarincang (561 ha ) Hazard maps, vulnerability maps and risk maps are urgently needed by the Serang District Government, in addition to being a reference for disaster risk reduction activities as well as for the sustainable arrangement of areas.

Taman Nasional Baluran memiliki kondisi geomorfologi dan iklim yang khas sehingga dapat membentuk sabana. Masalah yang terjadi di Taman Nasional Baluran adalah adanya perubahan penutup lahan seiring berjalannya waktu. Kondisi tersebut diikuti dengan perubahan struktur ekologi bentanglahan. Oleh karena itu, penelitian ini bertujuan untuk menganalisis pola penutup lahan berdasarkan aspek geomorfologi dan dinamika perubahannya di Taman Nasional Baluran. Teknik sistem informasi geografis dan penginderaan jauh digunakan untuk menginterpretasi kondisi geomorfologi dan penutup lahan. Analisis ini juga menggunakan software FRAGSTAT untuk mengkuantifikasi landscape metrics. Hasil penelitian menunjukkan bahwa setiap penutup lahan memiliki pola sesuai dengan kondisi geomorfologi. Temuan lain menunjukkan bahwa penutup lahan semak dan belukar, sabana, serta hutan lahan rendah mengalami perubahan luas secara signifikan selama tahun 1997-2019.  Fragmentasi yang terjadi pada penutup lahan di Taman Nasional Baluran, terutama sabana yang mengalami penurunan luas, turut mengancam kelestarian habitat flora dan fauna asli. Baluran National Park has unique geomorphology and climate conditions, so savannas possibly formed. The problem that happened in Baluran National Park is the land cover changes over time. The condition then followed by the change of landscape ecology structures. Therefore, this study aims to analyze land cover patterns based on geomorphological aspects and the change dynamics in Baluran National Park. Geographic information systems and remote sensing techniques were used to interpret the geomorphological and land cover condition. This analysis also used FRAGSTAT software to quantify landscape metrics. The result showed that each land cover has a pattern in accordance with geomorphological characteristics. Other findings showed that the land cover of shrubs, savannas, and lowland forests underwent significant changes during 1997-2019. The fragmentation that has occurred on Baluran National Park’s land cover, especially savannas that have decreased in area, also threatens the preservation of native flora and fauna habitats.
ACUMULACIÓN DE DEUDA PÚBLICA Y POLÍTICA FISCAL EN AMÉRICA LATINA
Authors: Zavaleta González Josué
Published: September 2020

La acumulación de deuda pública es uno de los problemas que más ocupa la atención del gobierno de cualquier economía. En relación con esto, desde un enfoque ortodoxo, las medidas de austeridad fiscal son la única alternativa para evitar y contrarrestar un grave problema de endeudamiento público. No obstante, recientemente se ha demostrado que la capacidad de estas medidas para resolver este problema es limitada y que incluso podrían agravarlo. En este contexto, y como una respuesta a las dificultades económicas que impondrá la crisis económica mundial por Covid-19, en este artículo demostramos tanto de forma teórica como empírica que una política fiscal expansiva, enfocada en incrementar la inversión pública, tiene la capacidad de reducir, o al menos controlar, la acumulación de deuda pública como porcentaje del producto interno bruto (PIB).

 

PUBLIC DEBT ACCUMULATION AND FISCAL POLICY IN LATIN AMERICA

ABSTRACT
Public debt accumulation is one of the problems to which governments pay more attention. In this regard, from an orthodox approach, fiscal austerity measures are the unique alternative to avoid and counteract a serious problem of public debt accumulation. However, it has recently been shown that the capacity of these policies to respond to this problem is limited and even could aggravate it. In this context, and as a response to the economic difficulties resulted from the global economic crisis imposed by the Covid-19, the aim of this paper is to show theoretically and empirically that an expansive fiscal policy, focused on increasing public investment, could reduce, or at least control, the public debt accumulation as a percentage of Gross Domestic Product (GDP).
La problemática administrativo-fiscal de un país naciente: México, 1821-1824
Authors: Jauregui Luis
Published: September 2020

Este estudio parte de la idea de que no se puede entender la situación financiera de los gobiernos postindependentistas sin tener conocimiento de la administración que se hacía cargo de los recursos públicos. En las siguientes páginas se analizan las oficinas que resguardaban los dineros públicos en una época de guerra interna; concretamente, la que llevó a la consumación de la independencia de Nueva España. Se concluye sobre la razón para el establecimiento del ministerio de hacienda. También se sugiere el motivo por el cual las juntas provinciales procedieron a formar sus propias administraciones financieras y se  aporta una razón más para el establecimiento del federalismo en 1824. El estudio explora el destino de los intendentes, cómo paulatinamente fueron perdiendo razón de ser en la administración provincial del México independiente hasta su desaparición por motivo del establecimiento de la nueva administración financiera de la república federal.
De la neutralidad valorativa a un nuevo pacto social entre ética, ciencia y tecnología
Authors: Francisco Velázquez Hugo José
Published: September 2020

La concepción estándar de la ciencia considera que el conocimiento científico implica un saber racional, objetivo y fiable. Desde esta perspectiva, se entiende, por un lado, que la ciencia debe prescindir de los juicios de valor y, por otro, que el conocimiento científico y sus aplicaciones son éticamente neutras. Así, los científicos y tecnólogos no son responsables moralmente por el uso que se haga de los conocimientos y aplicaciones que ellos han ayudado a producir. Habitualmente, esta posición se conoce, como la tesis de la neutralidad valorativa de la ciencia. El presente artículo pretende realizar un análisis crítico a dicha tesis a fin de determinar en qué medida puede hablarse de neutralidad axiológica en el ámbito científico y, consecuentemente, establecer hasta qué punto los científicos y tecnólogos son responsables moralmente por sus descubrimientos. Para ello, se toman como referencia los planteos de Maliandi, Jonas, Postman y Olivé. Esta revisión adopta una metodología cualitativa, basada en la teorización y reflexión crítica a partir del análisis bibliográfico o documental.
El contrapunteo entre imaginarios sociales y el desarrollo turístico: el caso de Costa Rica
Authors: Barboza Núñez Esteban
Published: September 2020

Este artículo reflexiona acerca de la relación entre los imaginarios sociales y los modos en que el turismo ha sido incentivado y desarrollado en el caso particular de Costa Rica. Se esboza una crítica al modo en que los modelos de desarrollo turístico en Centroamérica y el Caribe tradicionalmente han sido analizados, a la vez que se propone el concepto teórico de imaginarios sociales como una posibilidad de análisis del desarrollo turístico en la región. Seguidamente, explica las relaciones entre imaginarios sociales mayores y los modos en que Costa Rica se ha desarrollado como referente turístico en la región, y cómo esos imaginarios se reflejan en el espacio turístico, el paisaje, la iconografía y los discursos contemporáneos acerca del turismo en el país.

Kitaev's quantum double model as an error correcting code

Published: September 2020

Kitaev's quantum double models in 2D provide some of the most commonly studied examples of topological quantum order. In particular, the ground space is thought to yield a quantum error-correcting code. We offer an explicit proof that this is the case for arbitrary finite groups. Actually a stronger claim is shown: any two states with zero energy density in some contractible region must have the same reduced state in that region. Alternatively, the local properties of a gauge-invariant state are fully determined by specifying that its holonomies in the region are trivial. We contrast this result with the fact that local properties of gauge-invariant states are not generally determined by specifying all of their non-Abelian fluxes --- that is, the Wilson loops of lattice gauge theory do not form a complete commuting set of observables. We also note that the methods developed by P. Naaijkens (PhD thesis, 2012) under a different context can be adapted to provide another proof of the error correcting property of Kitaev's model. Finally, we compute the topological entanglement entropy in Kitaev's model, and show, contrary to previous claims in the literature, that it does not depend on whether the ``log dim R'' term is included in the definition of entanglement entropy.
The Beginning of the End for the Chinese Proletariat
Authors: Sørensen Bo Ærenlund
Published: September 2020

This article examines how China’s Communist Party (CCP) sought to justify its policies fostering inequality at the urban factory floor in the early years after Mao’s death through publications in the People’s Daily. The article focuses on three issues that emerged frequently in the newspaper: the increased prevalence of incentive wages, the abolishment of life-time employment for workers and the evolving discourse related to worker influence at their workplace. The article shows that the People’s Daily did not simply seek to persuade the public that the reforms were compatible with socialism, the newspaper also took great care to showcase which kinds of behaviours and emotions would be appropriate for the new working subject. The CCP’s dedication to reforming the population through the press makes the People’s Daily an excellent source for tracking norm intransigence on the part of the population. Based on the observation that the CCP sought to legitimate policies ending employment security many years before such policies were adopted, the article also suggests that public opinion had a direct influence on the timing of the early reforms.
