Authors: Marulanda Durango Jesser James , Escobar Mejía Andrés , Alzate Gómez Luis Alfonso 
Published: June 2017

Contexto: Una de las funciones de un filtro activo de potencia es calcular las consignas de corriente (i.e.: reducción de armónicos, corrección del factor de potencia, balancear las corrientes y voltajes) que compensen la fuente de alimentación. Existen en la literatura varios algoritmos que realizan esta función. El objetivo de este artículo es presentar los resultados obtenidos sobre el funcionamiento de cinco algoritmos propuestos en la literatura, bajo condiciones de voltajes distorsionados.Método: Consiste en la implementación de los siguientes algoritmos: potencia reactiva instantánea; factor de potencia unitario; compensación perfecta de armónicos; algoritmo pqr; y marco de referencia síncrono, en el programa de simulación Matlab – Simulink. Luego, usando un sistema eléctrico compuesto por cargas lineales y no lineales con características similares a un circuito real, se calcula la distorsión armónica total, el valor eficaz de la corriente de línea y de su componente fundamental, y el factor de potencia en la fuente trifásica. Se tomarán valores antes y después de la conexión a la red del filtro activo de potencia, considerando cada uno de los algoritmos por separado y manteniendo las mismas condiciones en el sistema para cada uno de ellos. También se calculan otras cantidades en el sistema de potencia para realizar la comparación. Resultados: Se muestran las corrientes de la red de alimentación antes y después de la conexión del filtro activo de potencia, además de la distorsión armónica de las corrientes y el factor de potencia. También se presenta la forma de onda del voltaje de continua del inversor con cada uno de los algoritmos utilizados, para evaluar el desempeño de un controlador de tensión que requiere el filtro.Conclusiones: En condiciones de funcionamiento con voltajes distorsionados en la red de alimentación, el algoritmo con mejor desempeño es el de compensación perfecta de armónicos, ya que este utiliza un filtro pasa bajo para mitigar los efectos de los armónicos de los voltajes sobre el cálculo de las corrientes de compensación.

Determination of dynamic impact factor for continuous girder bridge due to vehicle braking force by finite element method and experimental
Authors: Toan Nguyen Xuan , Duc Tran Van 
Published: June 2017

In this study, the finite element method (FEM) is used to investigate the dynamic response of continuous girder bridge due to moving three-axle vehicle . Vertical reaction forces of axles that change with time make bending vibration of girder significantly increase. The braking in the first span is able to create response in other spans. In addition, the dynamic impact factors are investigated by both FEM and experiment for Hoa Xuan bridge. The results of this study provide an improved understanding of the bridge dynamic behavior and can be used as additional references for bridge codes by practicing engineers.
The Myth of University Strategy. Market Niches and Organizational Careers of Russian Universities
Authors: Sokolov Mikhail 
Published: June 2017

Many attempts to build a typology of post-Soviet universities are based on the idea that a university development is an outcome of implementation of a strategy chosen by the organization’s managers. It is assumed that the choice of strategy is responsible for achievements and failures of a given organization. The article offers and statistically evaluates an alternative, non-voluntarist model of university evolution inspired by Carnegie School theory of organizations and a Lamarckian approach to organizational development. The model rests upon three assumptions: (i) organizations are economically motivated; (ii) they have no consolidated will, rather representing a conglomerate of internal agents that make decisions independently; (iii) organizations differ not so much in the nature of their decisions as in the chances for their successful implementation. These chances are predetermined by the starting points of university evolution: legal status (state/private, main/branch campus), belonging to a major “organizational family” (teacher training universities, colleges of arts and culture, etc. andgeographic location. Universities do not choose a development vector but find themselves in a narrow corridor imposed by the environment. The data of the Monitoring of Education Markets and Organizations surveyis used to demonstrate how an awareness of these elementary characters allows correctly predicting distribution of 75% of universities across four main types of university economies existing at the time. The 2013–2014 Monitoring of Educational Institution Performance indicates further that the distribution of gains from the “research turn” in state science policycan also be largely predicted from the universities’ ascriptive characters.
Calcium and Inorganic Phosphorous Levels in Stimulated and Unstimulated Saliva in Early Childhood Caries – A Comparative Study
Authors: Jolly Lisa R. , Shetty Amarshree 
Published: June 2017

Introduction:
Saliva, a chief player in the oral cavity, is determined by its secretion rate and quality to aid either in the development of caries, or its remineralization.6 The ability for saliva to function as a source of calcium and phosphate increases its supportive properties as it influences the precipitation or dissolution of calcium hydroxyapatite (HAP), the principal inorganic component of dental hard tissue.

Materials & Methods:
30 healthy children, aged between 3 and 6 years old were screened and recruited for the study at the Department of Pedodontics and Preventive Dentistry of the A.B Shetty Memorial Institute of Dental Sciences, a constituent of Nitte University. The subjects were clinically examined and scored based on their decayed, missing (due to caries) and filled surfaces (dfs) and were further categorized into two equal groups of 15.

Result:
In the subjects with Early Childhood Caries (ECC), the mean calcium concentration in samples of unstimulated saliva was 4.2383 ± 0.8594 and in samples of stimulated saliva was 4.1965 ± 0.6240. While, the mean inorganic phosphorous concentration in samples of unstimulated saliva was 3.219 ± 0.8540and in samples of stimulated saliva was 3.0634 ± 0.5470.

Conclusion:
From this study, we obtained a relationship between calcium, saliva and the caries status of children with the calcium concentration decreasing with increase in the caries status, as well as on stimulation of saliva.

Using Registered Dental Hygienists to Promote a School-Based Approach to Dental Public Health
Authors: Simmer-Beck Melanie , Wellever Anthony , Kelly Patricia 
Published: June 2017

We examine a strategy for improving oral health in the United States by focusing on low-income children in school-based settings. Vulnerable children often experience cultural, social, economic, structural, and geographic barriers when trying to access dental services in traditional dental office settings. These disparities have been discussed for more than a decade in multiple US Department of Health and Human Services publications. One solution is to revise dental practice acts to allow registered dental hygienists increased scope of services, expanded public health delivery opportunities, and decreased dentist supervision. We provide examples of how federally qualified health centers have implemented successful school-based dental models within the parameters of two state policies that allow registered dental hygienists varying levels of dentist supervision. Changes to dental practice acts at the state level allowing registered dental hygienists to practice with limited supervision in community settings, such as schools, may provide vulnerable populations greater access to screening and preventive services. We derive our recommendations from expert opinion.

Published: June 2017

An ever-present challenge for the oral health profession is to reduce the extent of oral disease among racial and ethnic minority populations. Adding to this complex dilemma is the linkage between oral health and systemic health. We describe enhanced cultural competency, in the context of individual cultural beliefs, values, language, practice, and health behaviors, among dental professionals, as one approach to meeting the dental care needs of the underserved. An overview and examples of teaching methods used by University of Florida dental educators to enhance student cultural competency is provided. Evidence-based evaluation results provide evidence of methodology efficacy. We conclude by describing actions that can be implemented by academic dental institutions to facilitate development of culturally competent practitioners.
Determinants of profitability according to groups of banks in Albania
Authors: Hallunovi Dr.Sc. Arjeta 
Published: June 2017

The paper analyzed the determinants of profitability of all the commercial banks in Albania, where the banks were analyzed by dividing into groups[1]. These determinants are categorized into two groups, internal and external factors. The objective of the study is to determine the factors that affect the profitability in commercial banks, to show how they differ according to groups of the banks and making some recommendations which can help the management. A panel data with all the commercial banks that operate in Albania is analyzed for the period 2009-2014. To measure the profitability is used the independent variable return on assets. Banking specific factors that are used in this study include variables such as bank size, asset management, credit risk, liquidity of assets, capital adequacy, operational efficiency and cost of financing. On the other hand is taken into consideration only one industry specific factor, which is the concentration and some macroeconomic factors as GDP, exchange rate and inflation. The quantitative data are obtained from the financial statements of commercial banks, INSTAT, Bank of Albania, World Bank and Bankscope, in order to make empirical analysis needed to identify and measure the determinants of bank profitability. In particular, the multiple regression analysis is used to measure the impact of determinants in bank profitability and to realize empirical analysis is used Eviews 7.The results of the study showed a positive relationship between bank size and profitability, statistically important in the group 2, with 1% level of significance. The credit risk had an inverse relation with profitability in the model, statistically significant at 1% level of significance for the group 2 and 5% for the group 1 and 3. While, in terms of macroeconomic factors, GDP had a positive relationship with profitability and it is statistically significant in the group 3. On the other hand, inflation and exchange rate showed a positive relation with profitability (ROA/ROE) but statistically insignificant for the model.[1] According to the Bank of Albania, in December 2014, banks in the Albanian sector are divided by size of activity: 1) The bank group 1 (0-2% of total banking sector assets) include United Bank of Albania, Veneto Bank, International Commercial Bank, First Investment Bank, Credit Bank of Albania; 2) The bank group 2 (2-7% of total banking sector assets) include Procredit Bank, Credit Agricole Bank, National Bank of Greece, Societe Generale Bank - Albania, Alpha Bank - Albania, Union Bank; and 3) The banks group 3 (about 7% of total banking sector assets) include Raiffeisen Bank, Credins Bank, National Commercial Bank, Intesa Sanpaolo Bank-Albania, Tirana Bank.

Published: June 2017

Background:The Infliximab, has proven effective in treating rheumatoid arthritis (RA). A good clinical response is usually associated with high serum drug levels. Development of antibodies toward Infliximab (ATI) can increase drug clearance, leading to treatment failure.Aims:To analyze whether serum Infliximab trough levels (ITL) at the induction phase are associated with Infliximab clearance and clinical outcomes at week(W) 54 and to investigate the association with immunogenicity development.Methods:Observational retrospective study in which ITL from 66 RA patients were measured by capture ELISA at W0, W2, W6, W14 and 22. Patients were classified as ITLpos if Infliximab was detectable at W54 and ITLneg otherwise. ATI were assayed by bridging ELISA and by two drug-tolerant assays. ITL cut-off values were established by ROC curves. The association between ITL at early-stage and clearance of Infliximab at W54 was analyzed by univariable and multivariable logistic regression.Results:ITLneg patients (n=25) always had significantly lower Infliximab levels than ITLpos (n=41). An ITL value of 4.4 μg/mL at W6 best predicted W54 Infliximab absence. In the multivariable analysis, only ITL below the cut-off at W6 (OR: 86.6; 95%CI: 6.58-1139.99) and non-use of methotrexate (OR: 6.9; 95%CI: 1.04-45.84) remained significantly associated with W54 Infliximab absence. ATI were more frequent in patients with ITL below the cut-off at W6.Conclusions:In RA, ITL at induction phase are inversely associated with Infliximab clearance and clinical outcomes at W54. ATI was the main reason for low early ITL. A predictive value of ITL at W6 was found as a useful prognostic measure of treatment efficacy.
THE SAVINGS AND LOAN DEBACLE: THE CULMINATION OF THREE DECADES OF CONFLICTING REGULATION, DEREGULATION, AND RE-REGULATION
Authors: Margavio Geanie W. 
Published: June 2017

The role of the public accounting profession in the savings and loan debacle of the 1980s has recently been the subject of Congressional inquiry and extensive litigation by government agencies, and by angry stockholders and bondholders. These efforts suggest a broad misunderstanding by the public of the causes of the disaster. this paper illustrates that the difficulties which precipitated the crisis were a result of the historical development of the regulatory environment of the savings and loan industry. Examining this regulatory environment helps in understanding the current problems and crises of savings and loans as well as the situation in which the accounting profession now finds itself.
The paper illustrates that the manner in which the industry was regulated, including piecemeal and often conflicting legislation, locked the industry into long-term mortgage commitments and then urged diversification from these commitments. The paper illustrates that, over the years, industry responses to this legislation created a net worth crisis. The extent of the crisis was obscured by accounting principles developed by regulators, and which ran contrary to GAAP. Finally, the paper discusses recent legislation designed to correct the regulatory and accounting inconsistencies, and the anticipated effect of this legislation on the future of the savings and loan industry.
EARLY ACCOUNTING IN NORTHERN ITALY: THE ROLE OF COMMERCIAL DEVELOPMENT AND THE PRINTING PRESS IN THE EXPANSION OF DOUBLE-ENTRY FROM GENOA, FLORENCE AND VENICE
Authors: Mills Geofrey T. 
Published: June 2017

This paper offers an explanation of why double-entry bookkeeping developed in the city-states of Northern Italy in the years 1200–1350, and then how it then spread from there to the rest of Europe. Increased economic activity initiated soon after the start of the Crusades, but then growing into an explosion of Italian trade by 1350, provided Genoa, Florence, and Venice with enormous trading opportunities. This expansion of trade created, in turn, the need for a much improved accounting technique. The spread of double entry was greatly abetted by the advent of cheap business arithmetics and grammars made possible by the invention of the moveable type printing. Venice was especially advanced in her printing industry during the years after 1500.
Thus, it was that the double entry system was created in Northern Italy between 1200–1350 primarily due to the development of the regional economy, and from there spread to the rest of Europe helped immeasurably by access to cheaply printed books.
THE DOUBLE-ENTRY BOOKKEEPING METHOD APPLIED IN SPAIN TO ACCOUNT FOR TRANSACTIONS RELATED TO THE MINTING PROCESS OF GOLD AND SILVER IN THE SIXTEENTH CENTURY
Authors: Anes Rafael Donoso 
Published: June 2017

This paper represents a summary of broad research undertaken in the Archivo General de Indias of Seville. Gold and silver were shipped from America, received in the Treasury Room, minted, and sold in public auctions to merchants. Because single-entry was the usual accounting method applied by the Casa de la Contratación de las Indias, it was surprising to find several books which provide evidence of the application of the double-entry accounting method to account for those transactions related to the minting process. The purpose of this paper is to demonstrate that the documents related to the accounting procedures of the Casa treasury represent the earliest evidence found of the utilization of the double-entry method by a public institution.
The study concludes that the treasury utilized the double-entry bookkeeping procedure as early as 1555 to account for the transactions involved in the minting process of gold and silver. Although the focus of this research is on the period 1555–1600, this method was utilized until the middle of the 17th century. This paper examines the accounting procedures used to account for the sale of gold and silver during 1560.
DEVELOPMENT OF CORPORATE ACCOUNTING IN AUSTRALIA1
Authors: Gibson Robert W. 
Published: June 2017

Corporate accounting in Australia can be said to have passed through four phases. The initial phase involved the introduction of minimum standards of statutory disclosure. The second phase was largely an extension of these statutory requirements to include income statements and consolidated statements. This was followed by the activities of the accounting profession, stock exchanges and others to improve the details of disclosure.
The final phase which is still under way has directed attention more and more to the problems of accounting measurement reflected in the financial statements. It has been marked by efforts to formulate accounting standards and to enforce compliance with those standards. Modern developments have been marked by a gradual shift from change based on statutory demands towards change based on the role of such non statutory influences as the accounting profession.
