GAMERGATE: cultura dos jogos digitais e a identidade gamer masculina
Authors: Goulart Lucas , Nardi Henrique Caetano
Published: December 2017

Tomando como ponto de partida o Gamergate – evento da cultura de jogos digitais, onde mulheres, LGBTQs e pessoas não-brancas foram hostilizadas e agredidas por sua atuação dentro da cultura de jogos digitais – dissertamos a respeito de como essas culturas se relacionam com a identidade do “homem nerd”. Compreendemos que esse evento é uma reação à possível mudança dessas culturas rumo a uma possibilidade mais inclusiva, o que colocaria em cheque tais identidades. Dessa maneira, investigamos como historicamente essa cultura se centra na promoção e “venda” dessa identidade nerd masculina, e como movimentos inclusivos e centrados em diversidade sexual e de gênero possibilitam diferentes impactos e acessos a esses contextos.
Religião e Política: medos sociais e extremismo religioso no Brasil
Authors: Cesar Larissa
Published: December 2017

“Religião e política: medos sociais, extremismo religioso e as eleições 2014” é um livro desenvolvido com o objetivo de entender o panorama político no Brasil contemporâneo a partir da análise das eleições 2014 nos cenários nacional e estadual. A utilização do conceito de “períodos frios” de Durkheim ajuda a compreender como os medos sociais e a ameaça de valores tradicionais propiciam o estabelecimento de um perfil comportamental extremista, explicitado na esfera pública para preservar tais valores através da manipulação de uma leitura bíblica admitida como fundamentalista.

RETÓRICA DOS ESTEREÓTIPOS, PRÁTICAS DISCURSIVAS E PERFORMANCES CONTEMPORÂNEAS
Authors: Deusdará Bruno , Nery Guilherme
Published: December 2017

Em uma rápida e intensa alteração das configurações do debate público na cena republicana brasileira, temos observado a emergência insistente e reiterada da atualização de estereótipos e imagens cristalizadas tradicionais excludentes que ora se reforçam, ora se inscrevem em performances de combate. Esse redimensionamento, que se realiza pela intensidade de traços conservadores e excludentes, parece apropriar-se de modo singular das práticas discursivo-midiáticas, necessitando ser mais bem entendido, a partir de uma torção da compreensão a respeito da trajetória recente de consolidação das lutas por direitos empreendidas pelas chamadas minorias. Se essa torção se caracteriza, como aponta Rancière, pelo pretenso “combate à inflação dos direitos sociais”, fica evidente seu vetor autoritário e restritivo.
The use of generalised audit software by internal audit functions in a developing country: A maturity level assessment
Authors: van der Nest Daniel P. , Smidt Louis , Lubbe Dave
Published: December 2017

This article explores the existing practices of internal audit functions in the locally controlled South African banking industry regarding the use of Generalised Audit Software (GAS), against a benchmark developed from recognised data analytic maturity models, in order to assess the current maturity levels of the locally controlled South African banks in the use of this software for tests of controls. The literature review indicates that the use of GAS by internal audit functions is still at a relatively low level of maturity, despite the accelerating adoption of information technology and generation of big data within organisations. The empirical results of this article also confirm that the maturity of the use of GAS by the internal auditors employed by locally controlled South African banks is still lower than expected, given that the world, especially from a business perspective is now fully immersed in a technological-driven business environment. This study has since been extended to other industries in the following countries namely, Canada, Columbia, Portugal and Australia.
Company performance and reputation risk in state-owned Italian listed companies
Authors: Cavallini Iacopo , Iacoviello Giuseppina , Trucco Sara
Published: December 2017

The relationship between ownership structure (private vs State-owned) and company performance has been deeply analyzed by scholars and practitioners. Prior studies found mixed results about this topic; some scholars demonstrated that private firms perform better than State-Owned Enterprises (SOEs) and others came to opposite or undefined results. Further, during the global financial crisis, this topic gained relevance. To our best knowledge, Italian framework suffers of a lack of these studies and, in particular, no ones focused on the level of reputation risk in both SOEs and private firms. Aim of this paper is to analyse the difference in the performance and in the reputation risk between Italian SOEs and private firms. To do so we performed a t-test analysis on a sample of 18 State-owned listed firms and 212 private listed firms. Our empirical results found that SOEs have higher ROE and higher Cash flow/sales, but a lower Tobins’ Q than private firms. Further, no statistically significant differences in the reputation risk have been found; therefore financial analysts do not perceive any difference in the reputation risk between private and SOEs. Our results can help practitioners and policy-makers in making investment decisions and choices about the privatization process.
The impact of the presence on global markets of calcium carbide originating from China on other industry role players: The case of calcium carbide (PTY) LTD
Authors: Mazo Royce Sitshonile , Munapo Elias
Published: December 2017

This research assesses how the presence of calcium carbide originating from China has impacted on the operations of other role players in the industry. SA Calcium Carbide (Pty) Ltd. located in Newcastle, South Africa, was used as a case study. The study spanned all markets where the company has a footprint meaning domestically, regionally and internationally. The aim of the study was to discern the extent to which companies like SA Calcium Carbide have been affected by the presence of products from China on the global market with special focus being put on the competitiveness in terms of pricing of products. The study used a survey strategy, and was exploratory in nature. The choice of the survey strategy was motivated by the need to collect both quantitative and qualitative data in order to meet the research objectives. The data was gathered, with an 80 percent response rate, using a questionnaire method from more than 70 current SA Calcium Carbide customers both from the domestic and the export side of the business. In order to consider the different perspectives of the whole scenario, 10 companies involved in either manufacturing or trading of Chinese manufactured calcium carbide were interviewed, some face to face and some telephonically. The study revealed that current customers, who are predominantly from the African continent, buy product from SA Calcium Carbide primarily because of its high quality. It also evident from the results that the export volumes of SA Calcium Carbide were on a gradual downward trend due to loss of market share to Chinese companies.

Published: December 2017

Os vários tipos de daltonismo limitam a percepção de cores e afetam como as pessoas interagem com o mundo, em particular quando as cores têm significados associados. Mesmo com empatia, designers não daltônicos enfrentam dificuldades para conceber interfaces acessíveis para usuários daltônicos, porque percebem as cores de uma forma distinta deles. Este trabalho analisa como simuladores e ferramentas assistivas para daltonismo podem apoiar o design de interfaces. Realizamos uma pesquisa por softwares gratuitos no Google, na loja de aplicativos do Android e na loja de extensões do navegador Chrome. Identificamos 4 tipos de simuladores de daltonismo (filtros de imagem, de tela, de sites e de câmera de dispositivo móvel) e 3 tipos de tecnologias assistivas (sites web, aplicativo móvel e editor de CSS). Sigilo, acesso à internet, tempo de uso e outros fatores foram considerados para analisar o emprego destes simuladores e tecnologias assistivas como suporte à análise estática e dinâmica de interfaces, durante avaliações formativas ou somativas.
ÁUDIO DINÂMICO: O DESIGN DE SOM NOS AMBIENTES INTERATIVOS
Authors: Carvalho Luiz Roberto , Theresinha Cybis Pereira Alice
Published: December 2017

Nos ambientes interativos, o uso do som não tem avançado como tecnologia na mesma proporção de desenvolvimento dos elementos gráficos, e a predominância do estímulo visual tem feito com que usuários – e desenvolvedores – tomem a ausência do estímulo sonoro como um padrão. Como resultado, tem-se experimentado um universo de interfaces não-sonoras ou poluídas acusticamente. No entanto, nos últimos 20 anos, uma série de esforços tem sido conduzidos por diversos pesquisadores para que o som adquira significado e relevância na área de IHC. O presente estudo objetiva sumarizar tais esforços, bem como expor os conceitos pertinentes do áudio dinâmico, e contextualizar sua aplicação. Ao levantar tais questões, busca-se contribuir para que as discussões acerca do design de som e do design de interface adquiram relevância, e a temática de estudo venha a se desenvolver de modo consistente.

A novel inheritance mechanism for modeling knowledge representation systems
Authors: Krótkiewicz Marek
Published: December 2017

The mechanism of inheritance is a powerful tool used to describe complexity of a reality fraction. It is particularly important for knowledge representation systems modelling. It provides a specific ability to take over properties from a base element, what is crucial for conciseness, and modelling efficiency as well. In the Association-Oriented Database Metamodel, inheritance retains coherence with the object-oriented model in the most general terms. However, it has been otherwise defined which stems from the specificity of the metamodel, and particularly from its capabilities which have blazed a trail for its further extension. The main contribution of this article is a description of preliminary assumptions, postulates and conceptual solutions applicable to inheritance. They have been discussed against the background of the Association-Oriented Database Metamodel as well as an objectoriented model compared with the former.
The inextricable entanglement of argumentation and interpretation in law
Authors: Markovic Milos
Published: December 2017

At the basis of tireless efforts to explain the nature of law lies the
question of how judges should decide cases. Therefrom arises a need for a
theory that would clarify the role of the courts and, moreover, provide
guidance to them on reaching judgments. The history of legal theory abounds
with various attempts to offer a generally acceptable answer to the question
raised. The fervor of debate and the perpetual dissatisfaction with offered
solutions prompted the thought of untamable arbitrariness of judges. In the
contemporary debate the significance of argumentation is particularly
emphasized as a link of the court procedure which provides reasonableness
and therewith justification and persuasiveness of the decision. Before
going into the matter, I will indicate in broad strokes which areas of legal
theory do argumentation and interpretation belong to. The purpose of setting
a conceptual framework is to prevent losing sight of the whole as well as to
limit the scope of discourse to a certain section of legal issues. The
second part deals with the concept of argumentation in general and some
specific features of the argumentation in law. The third part examines the
role of legal interpretation and draws a clear distinction between the
interpretation as a process and the interpretation as a result. At the end
of the discussion I shall put forward a thesis that the interpretation as a
process is argumentation, while the interpretation as a result is an
argument in the justification of judgment.
Against deflation of the subject
Authors: Nesic Janko
Published: December 2017

I will argue that accounts of mineness and pre-reflective self-awareness can
be helpful to panpsychists in solving the combination problems. A common
strategy in answering the subject combination problem in panpsychism is to
deflate the subject, eliminating or reducing subjects to experience. Many
modern panpsychist theories are deflationist or endorse deflationist
accounts of subjects, such as Parfit?s reductionism of personal identity and
G. Strawson?s identity view. To see if there can be deflation we need to
understand what the subject/self is. One aspect of consciousness left
unexplored and unappreciated by panpsychist theories is pre-reflective
self-consciousness/self-awareness. Theories of the self, inspired by
phenomenology, that are serious about subjectivity, could be of use in
arguing against the deflationary reductionism of the experiencing subject.
These theories show that there is more to the subject of experience than
just its experiences (qualities). Even without arguing for any precise
account of the nature of the self, it can be shown what phenomenology of
subjective character of consciousness and pre-reflective self-awareness
contributes to the combination problem debate.
Relation of science and political ideology with examples from science and education field in relations between USSR and FPRY
Authors: Korolija Maja
Published: December 2017

Our intention is to consider the relation between science and political
ideology in the case of the dynamics of the relation between the FPRY and
the USSR, i.e. their science policies. In that sense, we will analyze the
history of cooperation and the practical consequences of the break in 1948,
in the field of the educa?tional and scientific system of the FPRY, while
considering economic and polit?ical transformation in context of the Cold
War. We will show that in the scientific field in the FPRY, a transformation
has also begun in accordance with this liberal turn, which in ideological
terms led the society to the new ruling paradigm - Titoism. In relation to
the previous, Marxist-Leninist position - due to which Yu?goslavia, in terms
of science policy and organization of science, as well as other fields, was
modeled after USSR - the focus now has been moved from the thesis of
interweaving science and social needs to the idea of ?sovereignty? of
science. Tangible consequences of the influence of these liberal ideological
elements in science and the educational system were a departure from social
problems and atomization of scientific organization, while in the
educational field, among oth?er things, a decrease in the literacy rate is
noted. Through this analyses of the scientific and educational social
position in the context of these political chang?es, the conclusion can be
drawn that this field, just like other social fields, was more or less
subordinated to the market needs.

Authors: Kovacevic Bozidar , Kuzmic-Jankovic Snezana , Milev Bosko , Skuletic Vesna
Published: December 2017

Introduction. Frequent coexistence of papillary thyroid carcinoma (PTC) and Hashimoto?s thyroiditis (HT) indicates their immunological connection, with no consensus on the cause and effect of this relationship. The aim of this report is to present an unusual case of occurrence of multifocal papillary thyroid microcarcinoma in severe thyroid atrophy as a result of the end stage of HT and to analyze its clinical significance. Case outline. A 59-year-old female patient with a 14-year-long history of HT was admitted for the surgical treatment of a cytologically suspected PTC. During disease evolution, ultrasound controls were performed once a year and the findings showed a progressive decrease in thyroid volume. The nodule in the right lobe was detected for the first time in 2014. After a one-year follow-up, the nodule size was 7 mm. Fine needle aspiration biopsy was performed and was reported as ?suspicious for PTC.? The patient underwent total thyroidectomy. Intraoperatively, thyroid gland was indistinguishable from the surrounding tissue and histopathological intraoperative consultation was performed in order to confirm malignancy and thyroid tissue. After gross examination, all surgical specimens weighed less than 3 g. A final diagnosis of multifocal papillary thyroid microcarcinoma with bilateral presentation and extrathyroidal extension was made. Seventeen months after total thyroidectomy was performed, the patient was well, with no evidence of metastasis or recurrence of papillary carcinoma. Conclusion. In the circumstances of severe thyroid atrophy, papillary microcarcinoma with infiltrative growth can lead to early extrathyroid extension, and even to the infiltration of surrounding structures.

In this study, we deal with the inverse nodal problem for Sturm-Liouville equation with eigenparameter-dependent and jump conditions. Firstly, we obtain reconstruction formulas for potential function, q, under a condition and boundary data, ?, as a limit by using nodal points to apply the Chebyshev interpolation method. Then, we prove the stability of this problem. Finally, we calculate approximate solutions of the inverse nodal problem by considering the Chebyshev interpolation method. We then present some numerical examples using Matlab software program to compare the results obtained by the classical approach and by Chebyshev polynomials for the solutions of the problem.

An application of cubic B-Spline finite element method for the Burgers` equation
Authors: Aksan Emine
Published: December 2017

It is difficult to achieve exact solution of non-linear PDE, directly. Sometimes, it is possible to convert non-linear PDE into equivalent linear PDE by applying a convenient transformation. Hence, Burgers? equation replaces with heat equation by means of the Hope-Cole transformation. In this study, Burgers? equation was converted to a set of non-linear ODE by keeping non-linear structure of Burgers? equation. In this case, solutions for each of the non-linear ODE were obtained by the help of the cubic B-spline finite element method. Model problems were considered to verify the efficiency of this method. Agreement of the solutions was shown with graphics and tables.

Analysis of the integrated intensity of the central peaks calculated as a function of temperature in the ferroelectric phase of lithium tantalate
Authors: Kiracı Ali , Yurtseven Hamit
Published: December 2017

The integrated intensity of the central peak is calculated as a function of temperature in the ferroelectric phase (T < TC) of nearly stoichiometric LiTaO3. This calculation is performed using the temperature dependence of the order parameter obtained from the mean field theory at temperatures lower than the transition temperature TC (TC = 963 K) of this crystal. The calculated values of the order parameter (squared) are fitted to the integrated intensity of the central peaks as observed from the Raman and Brillouin scattering experiments as reported in the literature in the ferroelectric phase of nearly stoichiometric LiTaO3. Our results are in good agreement with the observed behavior of LiTaO3 crystal. Because of the applications of LiTaO3 in several academic disciplines including the material science and thermal science, it is beneficial to investigate dynamic properties of this crystal such as the damping constant, inverse relaxation time and the activation energy as also we studied here.

A comparison of porous structures on the performance of slider bearing with surface roughness in micropolar fluid film lubrication
Authors: Rao Pentyala , Murmu Birendra , Agarwal Santosh
Published: December 2017

This paper presents the theoretical analysis of comparison of porous
structures on the performance of a slider bearing with surface roughness in
micropolar fluid film lubrication. The globular sphere model and Irmay?s
capillary fissures model have been subject to investigations. The general
Reynolds equation which incorporates randomized roughness structure with
Stokes micropolar fluid is solved with suitable boundary conditions to get
the pressure distribution, which is then used to obtain the load carrying
capacity. The graphical representations suggest that the globular sphere
model scores over the Irmay?s capillary fissures model for an overall
improved performance. The numerical computations of the results show that,
the act of the porous structures on the performance of a slider bearing is
improved for the micropolar lubricants as compared to the corresponding
Newtonian lubricants.
MondoA Is an Essential Glucose-Responsive Transcription Factor in Human Pancreatic β-Cells
Authors: Richards Paul , Rachdi Latif , Oshima Masaya , Marchetti Piero , Bugliani Marco , Armanet Mathieu , Postic Catherine , Guilmeau Sandra , Scharfmann Raphael
Published: December 2017

Although the mechanisms by which glucose regulates insulin secretion from pancreatic β-cells are now well described, the way glucose modulates gene expression in such cells needs more understanding. Here, we demonstrate that MondoA, but not its paralog carbohydrate-responsive element–binding protein, is the predominant glucose-responsive transcription factor in human pancreatic β-EndoC-βH1 cells and in human islets. In high-glucose conditions, MondoA shuttles to the nucleus where it is required for the induction of the glucose-responsive genes arrestin domain–containing protein 4 (ARRDC4) and thioredoxin interacting protein (TXNIP), the latter being a protein strongly linked to β-cell dysfunction and diabetes. Importantly, increasing cAMP signaling in human β-cells, using forskolin or the glucagon-like peptide 1 mimetic Exendin-4, inhibits the shuttling of MondoA and potently inhibits TXNIP and ARRDC4 expression. Furthermore, we demonstrate that silencing MondoA expression improves glucose uptake in EndoC-βH1 cells. These results highlight MondoA as a novel target in β-cells that coordinates transcriptional response to elevated glucose levels.

Published: December 2017

OBJECTIVE

We performed a secondary analysis to evaluate the effect of the Women’s Health Initiative dietary intervention on incident diabetes and diabetes treatment in postmenopausal women.

RESEARCH DESIGN AND METHODS

A total of 48,835 women were randomized to a comparison group or an intervention group that underwent a behavioral/nutritional modification program to decrease fat and increase vegetable, fruit, and grain intake for an average of 8.1 years. Ninety-three percent of participants completed the intervention, and 71% participated in active follow-up through 30 September 2015 (median 17.3 years). We measured time to development of treated diabetes and progression from oral antihyperglycemic agents to insulin. Serum glucose and insulin were measured in a subsample of women (N = 2,324) at baseline and years 1, 3, and 6.

RESULTS

During the trial, intervention group women had lower rates of initiation of insulin therapy (hazard ratio [HR] 0.74 [95% CI 0.59, 0.94]; P = 0.01). Moreover, women with baseline waist circumference ≥88 cm (P interaction = 0.01) and worse metabolic syndrome scores (P interaction = 0.02) had the greatest reduction in risk of initiating insulin therapy. The decreased risk from the intervention was present during the cumulative follow-up (HR 0.88 [95% CI 0.78, 0.99]; P = 0.04). In participants with measured biomarkers (5.8% subsample) who had baseline glucose <100 mg/dL, the intervention reduced the risk of developing glucose ≥100 mg/dL by 25% (odds ratio 0.75 [95% CI 0.61, 0.93]; P = 0.008). Adjustment for weight change did not alter the results.

CONCLUSIONS

In this secondary analysis, a dietary intervention in postmenopausal women aimed at reducing fat and increasing intake of vegetables, fruits, and grains did not increase risk of diabetes and may have slowed progression.
Positive Impact of a Pilot Pharmacist-Run Diabetes Pharmacotherapy Clinic in Solid-Organ Transplant Recipients
Authors: Newland David M. , Edwards Angelina R. , Hall Reed C. , Maxwell Pamela R.
Published: December 2017

Purpose.

Post-transplant diabetes mellitus (PTDM) can lead to significant morbidity and cardiovascular death with a functioning graft. A paucity of literature exists regarding glycemic control in solid-organ transplant (SOT) recipients, including pharmacist management of PTDM. This study aimed to assess the impact of pharmacist interventions on diabetes management in a pharmacist-run PTDM clinic.

Methods.

This was a single-center, prospective, observational study of 24 adult SOT recipients enrolled in a pilot pharmacist-managed PTDM clinic from 1 January to 30 June 2015.

Results.

Improvements were realized in markers of glycemic control, including changes in A1C, average daily self-monitoring of blood glucose (SMBG) results, fasting SMBG results, and pre-lunch SMBG results from enrollment through at least 3 months of follow-up. Median A1C decreased significantly from 8.05% (interquartile range [IQR] 6.33–11.75) at baseline to 6.45% (IQR 6.05–7.3) at the last follow-up encounter (P = 0.0010). Average daily SMBG results decreased significantly from a median of 191 mg/dL (IQR 138–232 mg/dL) at baseline to 125 mg/dL (IQR 111–167 mg/dL) at the final encounter (P = 0.0023).

Assessing the Appearance and Fluorescence of Resin-Infiltrated White Spot Lesions With Caries Detection Devices
Authors: Markowitz K , Carey K
Published: December 2017

Objective:

This in vitro study examined the effectiveness of caries detector devices in assessing the ability of resin infiltration (RI) (Icon, DMG-Hamburg, Hamburg, Germany) to improve the optical properties of enamel white spot lesions (WSLs).

Methods and Materials:

Ten caries-free third molars were used. Photographs, a subjective visual assessment of the photographs, fluorescent camera (FC) images using the Spectra (Air Techniques, Melville, NY, USA), and laser fluorescent (LF) readings using the DIAGNOdent (KaVo, Biberach, Germany) were obtained from each tooth's buccal surface. Specimens were coated with nail polish leaving a rectangular window on the buccal surface and placed in pH 4.5 lactic acid gel for two weeks to create a WSL. The WSLs were analyzed by the same methods. RI was applied to half of each WSL; final photographs were then taken, and caries detector assessments were conducted. FC images were converted to grayscale, and the fluorescent image's brightness intensity was measured using ImageJ. Data were analyzed with analysis of variance and Tukey-Kramer honestly significant difference test. Significance was set at α=0.05.

Results:

Subjective assessment of the photographs showed that RI improved the appearance of the WSLs so that they resembled intact enamel. Mean FC-brightness intensities for intact, demineralized, and demineralized RI-treated areas were 159.6 ± 9.2, 123.4 ± 7.2, and 160.9 ± 11.5, respectively. There were no significant differences in fluorescent intensity between the intact and RI areas (p=0.58). The demineralized areas had significantly lower fluorescent intensity than both the RI-treated and intact areas (p<0.001). LF values did not differ significantly between intact, demineralized, or RI-treated areas.

Conclusions:

This study demonstrates the ability of RI to restore artificial WSLs to the esthetics and fluorescence of intact enamel. The FC can be used to assess the optical properties of WSLs and the impact of RI on these properties.
Does Finishing and Polishing of Restorative Materials Affect Bacterial Adhesion and Biofilm Formation? A Systematic Review
Authors: Dutra DAM , Pereira GKR , Kantorski KZ , Valandro LF , Zanatta FB
Published: December 2017

Biofilm (bacterial plaque) accumulation on the surface of restorative materials favors the occurrence of secondary caries and periodontal inflammation. Surface characteristics of restorations can be modified by finishing and/or polishing procedures and may affect bacterial adhesion. The aim of this systematic review was to characterize how finishing and polishing methods affect the surface properties of different restorative materials with regard to bacterial adhesion and biofilm formation. Searches were carried out in MEDLINE-PubMed, EMBASE, Cochrane-CENTRAL, and LILACS databases. From 2882 potential articles found in the initial searches, only 18 met the eligible criteria and were included in this review (12 with in vitro design, four with in situ design, and two clinical trials). However, they presented high heterogeneity regarding materials considered and methodology for evaluating the desired outcome. Risk bias analysis showed that only two studies presented low risk (whereas 11 showed high and five showed medium risk). Thus, only descriptive analyses considering study design, materials, intervention (finishing/polishing), surface characteristics (roughness and surface free energy), and protocol for biofilm formation (bacterial adhesion) could be performed. Some conclusions could be drawn: the impact of roughness on bacterial adhesion seems to be related not to a roughness threshold (as previously believed) but rather to a range, the range of surface roughness among different polishing methods is wide and material dependent, finishing invariably creates a rougher surface and should always be followed by a polishing method, each dental material requires its own treatment modality to obtain and maintain as smooth a surface as possible, and in vitro designs do not seem to be powerful tools to draw relevant conclusions, so in vivo and in situ designs become strongly recommended.
CAPITAL IMPLICIT EXPENSES IN THE SHADOW ECONOMIC REVENUE
Authors: Tereshchenko Oleg , Voloshanyuk Natalia
Published: December 2017

In many countries related to emerging markets (EM), there is a high proportion of the shadow economy. The main source of shadow incomes replenishment are incomes that are actually generated in the official sector of the economy, however, they are withdrawn to the shadow segment. The article is dedicated to solving the actual task of income amount estimating that flows from the official sector of the economy to the shadow one. The paper shows that the amount of annual profits that "poured" into the shadow sector corresponds to the size of the hidden (implicit) payment for capital. The problem of shadow payment for capital is closely connected with the shadowing of profits, salaries and payments for the resources usage.
The causal relationship between risk premium, shadow economy and key macroeconomic parameters of individual countries are shown in the article. The average income to GDP per capita ratio in Ukraine and other EM countries is significantly lower than in developed countries. In addition, there is a low share of staff costs in the structure of costs of enterprises. Thus, in the EM countries, the orientation of the business to the interests of the shareholders is clearly manifested and the interests of the stakeholders are ignored. In emerging markets, an increase in risks primarily leads to an increase in the risk premium and the shadowing level, to rising prices and to a substantial reduction in real salaries.
For the estimation of real capital expenditures, it is advisable to use indirect methods, especially modification of capital assets pricing model (CAPM), adapted to the conditions of the EM. The proposed modification (hybrid crisis model) involves minimum usage of the data from the local financial market. It includes the following parameters: global risk-free rate of return, global market premium for risk, country risk premium, beta-factor, calculated on the basis of the analogue approach, and premium for specific risks of investing in a particular asset. According to our assumption, the shadow interest rate on capital is the difference between the expected return by CAPM and the averaged ROE that follows from the official reporting. Thus, the size of annual profits, "transferred" into the shadow sector, corresponds to the size of the implicit capital charge. The calculations made have showed a stable relationship between the level of country risks and the size of shadow revenues in the country.

Authors: Tarragó Griselda
Published: December 2017

Este artículo se propone explorar el llamado proceso de “reformas borbónicas” en el Río de la Plata en su etapa más temprana de la primera mitad del siglo XVIII, durante la gobernación de Bruno de Zavala. La pregunta que lo guía se refiere al impacto de estas nuevas estrategias sobre el universo político y cultural de la tradicional monarquía compuesta hispánica. La elección de este tema constituye un desafío y también una oportunidad para abordar el problema de la agencia monárquica en tiempos de Felipe V, y pretende instalar una mirada crítica sobre ciertos tópicos acerca del reformismo del periodo.
El Real de San Felipe y Santiago de Montevideo (1724-1749): plaza y fuerte de los Borbones en la afirmaci ón de la conquista de la Banda Oriental
Authors: Fucé Pablo
Published: December 2017

En este artículo se examinan las causas y modos en los que se desarrolló la fundación y establecimiento definitivo de la ciudad de Montevideo, actual capital de la República Oriental del Uruguay. Dicho proceso se concibe aquí como el primer paso de afirmación político-militar de los borbones de su centro político principal en la Banda Oriental, a partir del cual, y en una segunda etapa que ya ha sido estudiada en Uruguay (y que se desarrollará especialmente en la segunda mitad del siglo XVIII), ocurre la expansión, conquista y colonización del interior del territorio. Para explicar su formación se presentan las características salientes de la vida en la Plaza durante sus primeros años; en particular, sus dificultades de afirmación de autoridad local debido al control al que fueron sometidos por los agentes de la Monarquía instalados en Buenos Aires, ejemplificando asimismo el nuevo vínculo político que buscó unir a las élites locales con los representantes regios de la Casa de Borbón.
“Castigar los crímenes de la anterior administración”. El juicio contra los miembros del Directorio y del Congreso en 1820.
Authors: Polastrelli Irina
Published: December 2017

Este artículo analiza el proceso que el gobernador de Buenos Aires, Manuel de Sarratea, instruyó en 1820 contra los miembros del Directorio y del Congreso. El propósito es mostrar las dificultades derivadas de la cuestión de cómo evaluar el desempeño de quienes habían ejercido el poder político en un contexto de “provisionalidad permanente”. Se estudian el formato judicial y el tipo de delito imputado a los acusados, los conflictos jurisdiccionales y las disputas entre las autoridades políticas involucradas. El juicio condensa los dilemas que caracterizaron a la crítica coyuntura de 1820: cuestionamiento de autoridades y superposición de sujetos soberanos.
