Bioarqueología de Las Papas (Departamento Tinogasta, Catamarca): primeros resultados
Authors: Ratto Norma Rosa , Aranda Claudia , Luna Leandro
Published: July 2019

El pueblo de Las Papas es el más septentrional del Municipio de Fiambalá (Departamento de Tinogasta, Catamarca, Argentina) y está emplazado en plena Cordillera de San Buenaventura (2.678 msnm). Dentro del ejido se rescataron tres entierros denominados Las Papas-I (LP-I), Las Papas-II (LP-II) y Las Papas-III (LP-III), los cuales se encontraban en la periferia norte, en el lateral de una cancha de fútbol y a la entrada del pueblo, respectivamente. La distancia entre los entierros no supera los 200 metros; sin embargo, dentro de ese reducido espacio se ha identificado una importante variabilidad en las prácticas mortuorias en distintos períodos del desarrollo cultural, principalmente por las notorias diferencias en los acompañamientos, formas de colocación de los cuerpos y tipos de estructuras de inhumación. Se trata de tres entierros primarios simples que incluyen individuos masculinos (un juvenil, un adulto joven y un adulto medio) y que cubren un rango temporal desde los primeros siglos antes de la era cristina hasta el siglo XIII. En este trabajo se realiza una caracterización biológica, isotópica y del comportamiento mortuorio de los restos recuperados y se discute la presencia de indicadores de estrés por anemia en los tres individuos.

Authors: T Thoyyibah
Published: June 2019

Mobile applications have become a good learning tool. This application involves technology that can be accessed anytime and anywhere. But keep in mind also the progress of science and technology can not be separated from the development, discovery and progress of science in the heyday of Muslims. Islam is very influential in the world and even a great deal of learning is applied to certain methods. The aim of this study was to analyze the mobile learning of the Book of Fiqih in the Islamic Law of the Bulughul Haram by mapping knowledge and evaluation of SUMI (the Usability Measurement Inventory). This study uses a method adopted from KMSLC (Knowledge Management System Life Cycle). The results of this study are mapping knowledge and measuring the quality of a system.

Peace and the Transcendentals: The Case of Thomas Aquinas
Authors: Meinert John
Published: June 2019

In both the 20th and 21st centuries, there has been a lively debate concerning beauty’s transcendental status in Aquinas’ thought. Nobody, however, has noticed that this debate can be replicated with peace. Peace’s place vis-à-vis the transcendentals is also ambiguous. This paper argues that peace is not an independent transcendental, but a transcendental of the good. In peace’s positive and negative rationes, union/order and rest/tranquility, it is reduced to the transcendental good. Yet through this reduction, peace adds conceptual content to ens. Inasmuch as something is, it is ordered/in union. Inasmuch as something is, it is at rest/tranquil.
Scriptural Plurality in the Writings of Thomas Aquinas: The Case of Psalm 67, 7
Authors: Innocent Smith O.P.
Published: June 2019

Thomas Aquinas makes occasional references to the coexistence of multiple versions of the Bible. In particular, Thomas was familiar with several versions of the Latin Psalter used in liturgical and scholarly contexts. This article examines Thomas’s references to Ps. 67, 7 as a test case for understanding the role of scriptural plurality in his biblical hermeneutics. Thomas associates this verse with the theme of unity within religious life, the relation of the Eucharist to ecclesial unity, and ecclesial unity in itself. Thomas’s citations of alternate versions of this verse often appear to be consciously chosen in accord with his exegetical purposes.
Financial Liquidity as a Factor Determining the Economic Condition of Companies on the Capital Market in Relation to Bankruptcy Law in Poland
Authors: Bolek Monika , Gniadkowska-Szymańska Agata
Published: July 2019

The aim of this article is to present financial liquidity as a factor affecting the economic condition of the companies on the capital market in relation to the amended Bankruptcy Law in Poland. A study was carried out to determine the impact of liquidity on the increase in earnings per share and return on assets, indicators can be used to assess the economic condition of a company. As a result, logit and quadratic functions were examined and the parameters of the models provided a verification of the hypothesis. As a result, it was found that the good economic situation of a company related to the increase in earnings per share and profitability is affected by the increasing cash efficiency of assets and the decreasing value of the current ratio. It can therefore be concluded that according to theory, conducting a more aggressive policy in the area of liquidity results in an increase in the value of an economic entity and, therefore, its good economic condition, but the effect of overly aggressive policies may influence solvency, which is defined by Bankruptcy Law.
The Fiscal Effects of Economic Immigration on Subnational Government Finance in Poland
Authors: Poniatowicz Marzanna , Piekutowska Agnieszka
Published: July 2019

The aim of the paper is to analyse the effects of economic immigration on subnational government finance (SNG) in Poland. The goal to achieve is to answer the following research question: what are the fiscal effects of immigration on SNG budget revenues and expenditures. To answer this question, logarithmic models were developed. The analysis refers to the years 2007-2016. In this respect, data from Statistics Poland - referring to budget revenues and expenditures of communes, cities of district status, districts and voivodeships - were used. As far as immigration statistics are concerned, data from the Ministry of Family, Labour and Social Policy were used. The results indicate an increase in both revenues and expenditures of SNG as a result of immigration. Such results can be explained inter alia by the nature of migration - research were focused on economic immigration. Results confirm that the level of employment of foreigners is one of the determinants shaping the fiscal effect of immigration. Moreover, the impact of economic immigration on SNG budget revenues and expenditures depends on the structure of this budget. This explains the differentiated results of the analysis of the impact of immigration on SNG in different countries. The positive correlation between immigration and SNG revenues in Poland can be associated with a high share of subnational governments in personal income tax revenues as this tax is one of the main categories of SNG revenues. Furthermore, results show that the impact of immigration on local government budgets in Poland is modest. This confirms the conclusions drawn by other authors (e.g. Auerbach and Oreopoulos), that in the long term, immigration cannot be considered as a potential instrument for resolving fiscal imbalances.
Review of pallet pooling studies
Authors: Chen Chunhua , Ren Jianwei , A Yunga
Published: July 2019

Development of sharing economy has brought new opportunities to the development of green logistics. Pallet pooling is a typical type of sharing economy. It has been recently promoted in almost every country in the world. Researchers have reached a common agreement that establishing an effective pallet pool is of great importance to the pallets use efficiency. It is also believed that the implementation of pallet pool will substantially contribute to the economic and social development. Detailed analysis of pallet pooling such as benefit analysis, mode choose, pallet allocation model & algorithm, quality control, etc. are discussed in this paper. Based on literature review, several important problems are listed for future study. These problems are information management, supply chain management, rental pricing, pallets tracking and allocation, quality control, sustainable development (carbon emissions), and “internet plus pallet pooling”. Some suggestions on China’s pallet pooling development are proposed as well.
Exploring the Meaning Problem of Big and Small Data Through Digital Method Triangulation
Authors: Leckner Sara , Severson Pernilla
Published: July 2019

In this article, knowledge building through combinations of methods in a digital context is discussed and explored. Two types of digital bigger and smaller data-driven media studies are used as examples: digital focus groups and the combination of internet traffic measurements, surveys and diaries. The article proposes the concept of digital method triangulation. Digital method triangulation is argued to be a way to approach the “meaning problem” to make sense of small and big data. Digital method triangulation is argued 1) to stimulate the innovative use of known methods for unexpected dimensions within the studied topic; 2) with appropriate theoretical and meta-theoretical reflections, to provide more certainty in conclusions; and 3) to assist in constructing a more comprehensive perspective on specific analyses. The conclusion is that triangulation is even more important in the digital realm, as it facilitates dialogue between conventional and digital methods, dialogue that seems crucial to capture the complexities of the onlife.
Personality Filters for Online News Interest and Engagement
Authors: Eg Ragnhild , Krumsvik Arne
Published: July 2019

Our many online routines leave behind trails of data about our identities, habits, preferences and connections. These data serve as filters when we seek out information, yielding relevant results and content of interest. However, commercial and political parties can use the same data to personalize persuasive messages, and some even use psychological profiles to target individuals. With this revelation come concerns that news can be framed to appeal to individual personalities.

This study investigates the relationship between personality and news engagement among predominantly young Norwegian adults across different news angles. It addresses the Big Five personality traits as well as rational and experiential information-processing styles. The results provide support for our hypothesis on the relation between neuroticism and lowered news engagement, although the effect sizes are small. When exploring isolated news stories, we find greater differentiation among the participants, suggesting that individuals’ news interest really does start at the headline.

Authors: Wodnicka Alicja , Huzar Elżbieta , Dzięcioł Małgorzata , Krawczyk Maria
Published: July 2019

The yield, composition and fungicidal activity of essential oils obtained from fennel fruits cultivated in Poland (FEOPOL) and Egypt (FEO-EG) were compared. The influence of the duration of hydrodistillation using a Clevenger apparatus on the essential oil yield was studied. The composition of the fennel essential oils was determined by GC-MS method. Studies have shown that FEO-POL and FEO-EG are two distinct chemotypes, which differ in yield and composition. The fennel fruits cultivated in Poland contained 4.14% of essential oil with trans-anethole as a main component. The plant material from Egypt was characterised by low content of essential oil (1.32%) with a predominant share of estragole. The fungicidal activity was tested in vitro against ten species of pathogenic fungi. The best result for FEO-POL was achieved against Sclerotinia sclerotiorum, Rhizoctonia solani and Botrytis cinerea. Antifungal activity of FEO-EG against tested fungi was weak or none.
First report on the susceptibility of certain dry Egyptian common bean (Phaseolus vulgaris L.) (Fabaceae) varieties to infestation by Acanthoscelides obtectus (Say, 1831) (Coleoptera: Chrysomelidae: Bruchinae)
Authors: Gad Hassan Abdelrahim
Published: June 2019

Stored dry common bean seeds are subject to infestation by Acanthoscelides obtectus, which reduces the quality of the infested seeds and depletes their nutritional value, making them unfit for human consumption. The susceptibility of three Egyptian varieties to infestation by A. obtectus was investigated. The Nebraska variety was the most susceptible, with 34.5 and 62% infestation at artificial infestation levels that included 5 and 10 pairs of insects for every fifty seeds, respectively, followed by the Karnak and Giza 6 varieties. The maximum weight losses as a result of insect infestation were observed for Nebraska seeds, and as expected, the maximum numbers of emerged adults after 50 days of storage were also observed for this variety. Maximum means of infested seeds were recorded in the Nebraska and Karnak varieties at the 10- pair infestation level. According to the infestation index, the Giza 6 and Karnak varieties were moderately resistant, while the Nebraska variety was susceptible at the 10-pair infestation level. Moreover, changes in the chemical composition of infested dry common bean seeds were inconsistent, with increases in some nutritional properties (protein and fibre contents) and decreases in others (moisture, carbohydrate and fat contents).
Metonymy and frame integration: Interfacing between concepts and discourse
Authors: Ioannou Georgios
Published: July 2019

This article inquiries into specific aspects of the relation between conceptual contiguity found in metonymic shifts and the online construction of frames, seen as a dynamic process of construal. It first reviews the theory of metonymy regarding the conceptual, lexical and contextual facets of the phenomenon. It then explores the possibility of extending the conceptual relevance of metonymy beyond the traditional typological approach of metonymic categorization, re-interpreting it as a frame-integration mechanism, or blending, whereby two frames are brought together into an extended ICM. Metonymic blending is formulated as a partial integration between two input spaces discursively driven, whereby anad hocidentification of a referential commonness plays the role of the generic space of the blending. Subsequently, in the light of the assumption that frame-extension is not given categorically but it also includes – beyond its cognitive relevance – an interactional aspect, this analysis draws an interesting link: that between the generic space of metonymic blend, andcommon ground. The latter is precisely what facilitates the metonymic blend, regulating the distance between the integrated frames, at the same time remaining silent as discursively given information.

Authors: Calixto Igor Tupinambá , Prazeres Tereza Cristina M. de Melo
Published: July 2019

Introdução: Com o avanço da idade, o homem pode apresentar declínio na produção de testosterona, acarretando sinais e sintomas como diminuição da libido, disfunção erétil, redução da massa muscular, acúmulo de gordura corporal, redução da densidade mineral óssea, doença endotelial e sintomas depressivos. Esta síndrome clínica e laboratorial recebe o nome de deficiência androgênica do envelhecimento masculino (DAEM) e tem forte relação com a síndrome metabólica. Objetivo: Avaliar os efeitos da terapia de reposição hormonal em pacientes hipogonádicos. Material e método: Revisão bibliográfica de artigos publicados nos últimos 10 anos. No momento em que há o aumento da expectativa de vida, o desejo de envelhecer com qualidade de vida torna-se essencial a todo ser humano. A terapia de reposição da testosterona (TRT) no homem hipogonádico, pode reduzir os sinais e sintomas mencionados acima, porém nem todos os homens estão aptos a se submeter ao tratamento. Apneia obstrutiva do sono, sintomas prostáticos severos e eritrocitose devem ser tratadas antes de iniciar a terapia. Os portadores de câncer de próstata em atividade ou prolactinoma não podem fazê-lo, e entram no quadro de contra-indicações absolutas. Conclusão: A terapia de reposição de testosterona homens com deficiência androgênica típica da terceira idade é fortemente recomendada, uma vez que ela é capaz de amenizar os sinais e sintomas do envelhecimento, melhora a síndrome metabólica, possui poucas contra-indicações e as drogas utilizadas apresentam segurança farmacológica, o que facilita o tratamento desses pacientes.Palavras-chave: DAEM. Envelhecimento. Homem. Terapia de reposição da testosterona.

The Influences of Lengthening Dimension of Ro-Ro Ferry Toward the Considerations of Hydrodynamics Characteristic and Loading Capacity Aspect
Authors: Rachmianty Andi , Baso Suandar , Asri Syamsul
Published: June 2019

The ferry business has become an important business segment for ship designers, builders and operators. Therefore, many ways have been done in order to increase ferry business through the proper design or converting ships by lengthening. This research is focused on the influences of lengthening a Ro-Ro ferry to hydrodynamics characteristic and loading capacity aspects. Moreover, the ships also are fixed in the same width and draft dimensions. The difference of the Ro-Ro ferries length is indicated by the addition of one column of car space where one column car space is given by car size including distance between car columns spaces which is an increment of every 5.88 meter. The total resistances of Ro-Ro ferries are obtained by ship model experiment in towing tank. There are 4 ship models that are made. The lengthening a Ro-Ro ferry is described into non-dimensional parameter by the ratio of ship length and displacement volume (L/V1/3). The hydrodynamics and the loading capacity of carried car aspects could be described into the ratio of resistance and loading capacity of carried car (RT/SUK) with ship speed. The research result shows that the lengthening of a Ro-Ro ferry affects on total resistance, speed, and loading capacity of carried car. The increase of total resistance is caused by higher residual resistance at high speeds and this is experienced by small length size. Therefore by lengthening the Ro-Ro ferry it could reduce total resistance in the same speed especially the residuary resistance but eventhough lengthening Ro-Ro ferry the effective speed should be considered. In additions, the effective speed for actual ships dimension in the same Rt/SUK 0.05 i.e. B5L10 is about 13.85 knot, B5L11 14.33 knot, B5L12 14.94 knot, and B5L13 15.45 knot respectively.

Published: June 2019

C2 well is an exploration well located in south sumatera area managed by PT. MEPI in planned CSS field will be drilled to a depth of 12.000 ftTVD vertically. Planning the use of casing while drilling is done by using 16" protective casing on the trajectory 17-1/2" from a depth of 1.500 ft to 4.600 ft. The use of casing while drilling (CWD), is expected by using the casing as drillstring, then the clearance between the boreholes wall with the OD casing becomes small which will cause the event "Plastering Effect". This phenomenon is expected to isolate the wall of the drill hole which is easy to happen lost circulation. On vertical wells only need a casing method while drilling level-2 (non-retrievable) because at level-2 only casing with bits (drillshoe) only, where drillshoe will be left in the shoe casing. From the analysis results can be said on well C2 can be applied casing method while drilling because in terms of hydraulics drilling which the drill hole clearance with horsepower square inch method (HSI) and cutting lift based on cutting carrying index (CCI) is good, but for mechanics drilling needs to be considered torque, drag, and buckling loads. In terms of torque loads MLT Rings should be installed for 16” protective casing, from drag loads where the 2.000 HP rig can withstand maximum load of hookload, and 16" protective casing might not occur buckling as the maximum weight on bit (WOB) is still under critical buckling load.

Authors: Fernanda Vera , Ginting Mulia , Yulia Prayang Sunny
Published: June 2019

X-Field is located in South Sumatra, where there are several gas fields with considerable CO2 gas potential. In this field, no research has been conducted on CO2 injection neither in the laboratory nor simulation. Therefore, the purpose of this study is to analyze the effect of CO2 injection on the value of recovery factor with one-dimensional simulation using CMG. To be able to make an accurate simulation model, it is necessary to do validation by comparing the results obtained with the CO2 injection test from experiments in the laboratory. Laboratory experimental data used in this study is from Vulin’s literature. The result of recovery factor for X-field is 98.80%. From the results of this study, it is known that the injection rate of CO2 has no effect on changes in recovery factor. However, the difference of CO2 injection pressure in these two samples influences the change in recovery factor. The higher injection pressure of CO2 in an immiscible condition is, the higher the value of the recovery factor is achieved. In addition, the difference in oil composition in these two samples affects the value of MMP, where the higher the intermediate component of a reservoir fluid is, the lower the MMP will be. X-field has a high intermediate component fraction, therefore the value of MMP obtained is lower than the MMP from Vulin’s literature. The value of MMP in X-field is 2610.68 psia

Penelitian ini bertujuan untuk mengetahui model pengendalian persediaan atau dikenal dengan istilah Economic Order Quantity (jumlah pemesanan ekonomis) dan dapat diterapkan pada sistem produksi di PD Handi Meubel Cirebon. Pengendalian persediaan sangat penting diterapkan oleh suatu perusahaan karena dapat meminimalkan biaya persediaan. PD Handi Meubel telah melakukan perhitungan dengan rumus umum total biaya persediaan. Lebih lanjut, peneliti mencoba memberikan model perhitungan dengan model Economic Order Quantity (EOQ) yang dapat memberikan keputusan tentang jumlah pemesanan. Hasil pengendalian persediaan pada PD Handi Meubel belum ekonomis karena besar biaya pemesanan (annual ordering cost) dan biaya penyimpanan (annual holding cost) tidak relatif sama. Hal ini menyebabkan total persediaan tidak mampu mencapai nilai minimum. Penerapan model EOQ dapat memberikan solusi kepada PD Handi Meubel karena total persediaan dari perusahaan tersebut dapat mencapai nilai minimum. Ketentuan pemesanan diperoleh dari hasil perhitungan menggunakan persamaan model EOQ yang dikenal dengan istilah Wilson Formula. Tujuan jangka panjang dari penelitian ini bagi prodi pendidikan matematika yaitu sebagai desain bahan ajar pada materi atau pokok bahasan yang ada di dalam mata kuliah Kalkulus Diferensial yang berbasis pada model pengembangan bahan ajar tertentu sehingga diharapkan dapat membantu mahasiswa dalam memahami konsep-konsep esensial yang ada di dalam mata kuliah tersebut, sehingga kebutuhan belajar mahasiswa dapat terpenuhi dengan baik. Target luaran yang diharapkan terlaksana setelah penelitian ini dilakukan yaitu mempublikasikan hasil penelitian ini melalui publikasi ilmiah, prosiding, dan pengayaan bahan ajar. Dengan demikian diharapkan hasil penelitian ini dapat bermanfaat secara luas bagi perusahaan dan mahasiswa. Metode penelitian yang digunakan adalah metode observasi dengan sistem wawancara terhadap kepala produksi di PD Handi Meubel Cirebon.

Meloidogyne exigua is one of the most found species of nematodes in coffee plantations in the Brazilian Cerrado. Thus, the objective of the present study was to evaluate the efficiency of biological agents on two coffee cultivars. The experiment was carried out in a greenhouse using a completely randomized design. The treatments were arranged in a 2x3 factorial scheme, using repeated measures (two cultivars, 3 nematicides, and 2 additional controls), and were composed of two genotypes (Mundo Novo IAC 376-4 and IPR-100), three biological nematicides (B. methylotrophicus, B. subitilis, and T. asperellum), and two treatments including the three nematicides together, totaling 8 treatments and 2 controls, with 6 replicates each. The plants were inoculated with 3,780 eggs and J2s of the respective nematode. Throughout 150 days, the following variables were evaluated monthly: plant height, stem diameter, number of leaf pairs, and chlorophyll contents. At the end of this period (DAI), the reproductive factor (RF), egg mass and gall index were analyzed. About FR, the results were lower (<1) when using the cultivar IPR-100 when compared to the Mundo Novo genotype, denoting adequate genetic control. On the other hand, in the treatments with the susceptible genotype, high FRs were verified, ranging from 2.64 to 5.68 in the control. It was concluded that the bacterial mixtures were efficient in the control, and B. methylotrophicus contributed to higher plant height in the IPR 100 genotype.
ECONOMIC VIABILITY OF ARABICA COFFEE IN THE STATE OF ESPÍRITO SANTO CONSIDERING MANUAL AND SEMI-MECHANIZED HARVEST
Authors: GALEANO EDILEUZA VITAL , Krohling Cesar Abel
Published: June 2019

 Recent studies have shown that coffee production costs have been rising above inflation and that the activity has become less attractive to producers. One of the ways to try reducing costs is through the mechanization of activities. The objective of this study was to evaluate the production cost and economic viability of arabica coffee in the state of Espírito Santo, comparing manual and semi-mechanized harvest to different yield levels. For the feasibility analysis, the techniques of Net Present Value and Internal Rate of Return were used and the sensitivity analysis was used for risk assessment.  The results show advantages of semi-mechanized harvest. At the level of 50 bags per hectare, the activity was profitable considering the interest rate of 8%. In manual harvesting, the IRR is 8.3% and, in the semi-mechanized harvest, the IRR is 16%.  Producers must invest in higher yield levels with new technologies and mechanization to have greater return in the activity.

Published: June 2019

Petrol fiyatlarında meydana gelen değişimler hem petrol ihracatçısı hem petrol ithalatçısı ülkelerinin makroekonomik değişkenleri üzerinde etkili olabilmektedir. Petrol fiyatlarındaki artış (azalış) petrol ihracatçısı ülkeler için iyi (kötü) haber iken, petrol ithlatçısı ülkeler için kötü haberdir. Bu çalışmada gelişmekte olan petrol ihracatçısı ülkelerin arasından 10 ülke seçilmektedir. Bu ülkelerin 2003-2017 aylık verileri kullanılarak Brent tipi ham petrol fiyatlarının döviz kuru üzerindeki etkileri Westerlund (2007) panel eşbütünleşme testi yardımı ile araştırılmaktadır. Elde edilen ampirik bulgulara petrol fiyatlarındaki gelişmelerin gelişmekte olan petrol ihracatçısı ülkelerin reel döviz kuru üzerinde etkili olduğunu göstermektedir.
Angola Petrol Gelirlerinin ve Kurumsal Kalitesinin, Ekonomik ve Sosyal Yapıları Üzerindeki Etkileri

Ayrıca bir ekonometrik model kurularak, petrol üretimi ve fiyatları ile ekonomik büyüme arasındaki ilişkinin yanı sıra, petrolün, kurumsal kaliteyi gösteren hukukun kuralları üzerindeki etkisi ölçülmüştür. Ekonometrik model sonuçları, petrol üretimi ve fiyatlarının hem ekonomik büyüme hem de hukukun kuralları değişkenleri üzerinde kısa dönemde pozitif etkiye sahip olduğunu göstermektedir. Bu sonuca göre, ekonomik kalkınmayı gerçekleştirmek isteyen ülkelerin, doğal kaynaklarını ve kurumsal kalitesini de dikkate alarak, toplumun yaşam kalitesini yükseltecek şekilde uzun dönemli ve uygulanabilir bir ekonomik kalkınma programını oluşturması gerekliliği ortaya çıkmaktadır.Kaynak laneti teorisine göre, özellikle petrol zengini ülkelerin birçoğunun sürdürülebilir bir ekonomik büyümeyi ve kalkınmayı gerçekleştiremediği görülmektedir. Kurumsal kalitesi düşük, altyapısı azgelişmiş, yolsuzluk ve gelir eşitsizliği yüksek ve kaynak dışı sektör gelişimi az olan ülkelerde daha çok görülen bu durum, halkı yoksullaştıran ve yaşam kalitesini düşüren bir duruma neden olmaktadır. Bu çalışmada petrol üreticisi Angola’nın, kaynak gelirlerinin ve kurumsal kalitesinin, ekonomik ve sosyal yapıları üzerindeki etkileri, 2000-2018 dönemi için incelenmektedir. Araştırma sonuçlarına göre kurumsal kalite faktörünün, diğer bir ifadeyle hükümetlerin yönetişim becerisinin, ekonomik faktörlerden daha ön plana çıktığı ve kurumsal kalitenin, Angola’nın sosyo-ekonomik gelişimi üzerinde olumsuz etkilere neden olduğunu göstermektedir.
A FINANCEIRIZAÇÃO DAS CIDADES E A EMENDA CONSTITUCIONAL 95
Authors: Reis Ana Beatriz Oliveira , Attílio Luccas Assis
Published: June 2019

Nesse artigo analisamos o impacto da EC 95 sobre a financeirização urbana da economia brasileira. Especial atenção é concedida à tendência de mercantilização das cidades, ao mesmo tempo em que direitos sociais e participação popular na formulação de políticas públicas podem ser reduzidos em decorrência do aprofundamento do neoliberalismo no Brasil. Para essa análise, adotamos a metodologia interdisciplinar recorrendo a estudos de diferentes campos. As técnicas de pesquisa utilizadas são a revisão bibliográfica e a análise quantitativa. Nossas conclusões levam a crer que a histórica desigualdade social e econômica tende a se elevar em um contexto no qual as decisões da sociedade são cada vez mais pautadas pelo valor de troca em detrimento do valor de uso, e quando a riqueza social é apropriada por poucos indivíduos do setor privado. Contradições latentes do capitalismo serão reforçadas com os desdobramentos políticos do país.
