VEKALET TEORİSİ KAPSAMINDA ORTAYA ÇIKAN VEKALET MALİYETLERİNİN MUHASEBESİ VE RAPORLANMASI
Authors: ŞİŞMANOĞLU Elçin , KARAYİĞİT Durdane Tuğçe , KARABINAR Selahattin
Published: October 2020

Vekalet teorisi, birbirleri ile işbirliği durumunda olan tarafların motivasyonlarını, birbirlerini kontrol etme gereksinimlerini, aralarındaki bilgi akışını ve bu akıştan kaynaklanan sorunların çözümünü ele alan bir teoridir. Ekonomi, yönetim - organizasyon, satış - pazarlama ve muhasebe - finans gibi geniş alanda kullanılan, araçsallığı yüksek bir teoridir. Literatür taramasında vekalet teorisi ve asıl-vekil sorunları ile ilgili uygulamada farklı çalışmaların yapıldığı görülmekle birlikte, bu teori kapsamında vekalet maliyetlerinin neler olduğu ve finansal tablolarda nasıl raporlandığını konu edinen bir çalışmaya rastlanmamıştır. Bu çalışmada vekalet maliyetlerinin neler olduğu ve bu maliyetlerin finansal tablolarda hangi kalemler içinde raporlandığı ile ilgili kavramsal bir araştırma yapılması amaçlanmıştır.
Çalışmanın sonucunda vekalet maliyeti olarak sayılan kalemlerin zaten işletmenin genel giderleri içinde var olduğu (sütteki kaymak) ama vekalet maliyeti adını ve başlığını taşımadığı görülmüştür. Vekalet maliyetlerinin üst yönetime raporlaması için ayrı bir sisteme gerek olmadığı, tüm giderleri içinden süzülüp raporlanmasıyla çözülebilecek bir işlem olduğu sonucuna varılmıştır. Öte yandan sadece vekalet maliyetlerinin raporlanmasına ilişkin ayrı bir sistem kurmanın fayda/maliyet ölçütü açısından anlamlı olmayacağı görüşüne ulaşılmıştır.

Assim, este relato de pesquisa, ao colocar em evidência uma produção reflexiva sobre o uso da internet pelas artes visuais que aponta aspectos do trajeto que vem sendo feito na ocupação do ciberespaço como lugar de arte, traz contribuições para refletir sobre a situação atual.
Uma maloca-museu para Feliciano Lana, o filho dos desenhos dos sonhos
Authors: Baniwa Denilson
Published: October 2020

Quando um mestre morre leva com ele uma infinidade de experiências e conhecimentos, foi assim que nos sentimos quando perdemos o Sr Feliciano Lana, indígena do povo Desana que o Covid-19 levou nesta crise de saúde mundial. O texto que compartilho aqui é uma reivindicação ao que o Sr Feliciano Lana representa aos artistas indígenas contemporâneos e também uma tentativa de levar sua memória para além das fronteiras índio-aldeia. É preciso compreender a produção de Lana como uma importante geografia no que podemos repensar a arte brasileira, ou arte originária. O legado que Lana nos deixa é um banco de dados, conhecimentos mágicos e cotidianos que conectam os mundos, que precisam ser estudados, preservados e compartilhados com todos, principalmente com aqueles que ainda irão nascer. Enquanto índio-artista eu preciso cuidar da memória para que ela esteja presente nos pensamentos vivos, pois entender o passado é cuidar para que o futuro seja uma boa experiência para os que virão. É preciso enquanto artista pensar sobre uma arte-pussanga e uma maloca-museu para ampliarmos o sentido da arte.

Objetos desobedientes
Authors: Grindon Gavin
Published: October 2020

O artigo enfoca as culturas dos movimentos sociais - especificamente movimentos sociais autônomos, que têm sido uma forma de organização do movimento global dominante nas duas últimas décadas - e o interesse de algumas instituições em realizar exposições sobre eles. Especialmente, é analisada a pesquisa e desenvolvimento da mostra Objetos Desobedientes, curada pelo autor para o Victoria & Albert Museum (2014). Por objetos desobedientes, o autor entende os objetos de arte e design produzidos pelos movimentos sociais ativistas populares e independentes. O contexto dos movimentos, sua teoria e prática é o contexto primário para uma compreensão fundamentada da arte ativista, tantas vezes mal enquadrada de forma simplista nos debates abstratos e herméticos do mundo da arte, em abordagens teóricas e estéticas. Para tanto, a perspectiva adotada é a da História da Arte Social.
(A)Live or Dead @COVID19: ensaio para futuros artigos

Published: October 2020

Neo-biopolítica, pós-synopticon, o futuro é agora do reconhecimento facial à inteligência artificial: selfies mascaradas sob visualização (@maskvide), intermitente vigilância e controle dos dados em massa (Big Data), gazes e frequências capturadas através das não-mobilidades às Batcavernas (#datamask)… Neste “novo normal”, sem “casa dos artistas”, os BBB triunfam: a COVID-19 irá ‘solucionar-se’ somente após cada habitante, das nações no globo terrestre, estar devidamente “registrado, carimbado, avaliado, rotulado” pra poder voar - “dead or alive”. Ainda que os sobreviventes estejamos, no presente período ‘balão mágico’, experimentando em solo tupiniquim tanto a LGPD (recém aprovada, gerando inovações aos termos “I Agree”) quanto cotidianos espelhamentos narcísicos via múltiplas telinhas no tempo real (live), situamo-nos em contextos sociais vivos das relações sociais condicionadas aos meios de produção (GAFAM). Via YouTube vulnerabilizamo-nos na ação virótica também no digital. O século 21 demonstra, assim, como a webTV é uma tendência (i)material de nossos dias - a ponta do iceberg revolucionário preconizado por Guattari na década de 1970 ou, o outro lado da moeda, a fina membrana da sociedade do espetáculo que caminha à todo vapor coroando a representação de uma suposta liberdade de expressão em confinamento doméstico… Como brincar com tais conceitos - (in) visíveis e ‘indolores’ - quando aplicados, hoje, para além do espaço urbano? O presente ensaio projeta-se (design), portanto, em consonância à missão do intelectual (e/ou educador) que, frente aos paradigmas (áudio) visuais atuais, trata não em relatar mas em combater e, novamente como aprendiz, não mais em ser espectador e sim participante ativo às operacionalidades artísticas e tecnológicas que de nós se apropriam; que sejamos participadores deveras neste jogo da imperfeição repleta de ruídos e falhas na transmissão (da memória)! Seleção e tratamento dos gestos - métodos de montagem/ composição -, a fim de transformarmos tal um artifício (frequentemente condicionado pela moda numa pseudo--virtualização humana) em necessário confronto entre ambientes remotos desta ubiquidade dataveillance; como escrevera Benjamin contra o fascismo em carta a Adorno: “A tendência, em si, não basta”.

Imperfecciones en los mercados financieros y la regla óptima de tasas de interés
Authors: Rodríguez Arana Alejandro
Published: October 2020

Este trabajo presenta un modelo teórico útil para encontrar la regla de tasas de interés que minimiza una función que depende de la varianza del producto y la varianza de la inflación. En condiciones ideales esta regla respeta el principio de Taylor, por el cual la tasa nominal de interés de política se sobre ajusta a la inflación y sus expectativas. Sinembargo, en presencia de mercados imperfectos de crédito y/o de un numeroso grupo de personas excluido del sector financiero, la regla óptima puede no respetar el principio mencionado. Aun en estos casos, el modelo macroeconómico presenta trayectorias estables y definidas para la inflación y el producto.

Published: October 2020

Introduction: The acquired immunodeficiency syndrome remains a health challenge in Brazil. Therapeutic failures, characterized by detectable viral load, must have their causes evaluated. Among the most relevant reasons is the lack of adherence to treatment. Objective: To evaluate factors associated with inadequate control of viral load in individuals with HIV in the CAP of Itajubá (MG). Methods: This is an observational, cross-sectional and documentary study with 261 medical records. The variables analyzed were gender, age, education, residence, sexual orientation, first and last test results of tests for viral load and CD4+ T lymphocytes, history of poor adherence, use of current antiretroviral therapy (ART), duration of ART use, depression and/or anxiety, use of illicit drugs, follow-up time at the CAP. Results: Of the patients, 90.42% had an undetectable viral load and 64.37% had a CD4+ T count ≥500 in the last available test. Some characteristics were related to detectable viral load in the last exam: history of poor adherence during treatment (p<0,0001), inconsistent use of ART (p<0,0001) and use of illicit drugs (p=0,0155). Anxiety and/or depression was not statistically significant (p=0,3321). Conclusion: History of poor adherence, inconsistent use of ART and use of illicit drugs were associated with an increased risk ok virological failure. The identification of groups at risk of poor adherence to treatment can support the development of intervention strategies in an early and transdisciplinary way to improve adherence and generate better results in the control of HIV infection.

Authors: Firdaus Firdaus , Ismail Ismail
Published: October 2020

Quadcopter UAV development is happening very rapidly. One of the most important in the navigation system is the hardware and software or the used algorithm. Improving the accuracy of Quadcopter positioning is one of the most popular topics in the UAV field. This position parameter is determined by the GPS module. GPS modules produce position and speed information with a high degree of precision, but these modules are vulnerable to interference. Thus, GPS signals are often lost. Moreover, GPS measurements also cannot meet the real-time requirements. Both GPS U-Blox variants, Neo-6M, and M8N become the main problem by testing which are more precise and consistent with the actual geographical position indicated by Google map. Data obtained from GPS receivers are parsed and converted to longitude and latitude coordinates by the ATmega328 IC microcontroller then combine with real-time data from RTC DS1370 and stored continuously in a 2 GB SD card. The transferred geographic coordinate data would be retrieved and converted to CSV format so that it can be plotted into a map. The test was conducted where the Neo-6M GPS receiver was carried out
