The Effects of Clawbacks on Auditors' Propensity to Propose Restatements and Risk Assessments
Authors: Brink William D. , Grenier Jonathan H. , Pyzoha Jonathan S. , Reffett Andrew , Zielinski Natalie
Published: July 2019

The Sarbanes-Oxley Act of 2002 and the Dodd-Frank Act of 2010 include clawback provisions requiring executives to pay back incentive-based compensation that they earned based on financial statements that are subsequently restated. These provisions intend to reduce unethical behavior, as executives may be less likely to manipulate the financial statements to increase incentive compensation. However, prior research finds that at times executives are less willing to restate financial statements when a company has adopted a clawback (Pyzoha 2015). Relatedly, this paper summarizes the results of a recent study (Brink, Grenier, Pyzoha, and Reffett 2018) that investigates whether auditors might be less likely to propose restatements in the presence of a clawback. Contrary to expectations, results of three experiments, paired with survey and interview data, indicate the presence of a clawback has no effect on auditors' propensity to propose restatements. We discuss implications for practice and provide suggestions for future research.
Earnings Management in Firms with Data Security Breaches
Authors: Xu Howard , Guo Savannah (Yuanyaun) , Haislip Jacob Z. , Pinsker Robert E.
Published: July 2019

Anecdotal research suggests that management is concerned about how Data Security Breaches (DSBs) impact a firm's financial performance. We investigate: whether managers in DSB firms manipulate earnings through real earnings management (REM) and/or accrual-based earnings management (AEM); how breach type, disclosure delay, and external monitoring impact earnings management activities; and how earnings management activities influence a DSB firm's performance.

Using a propensity score matched sample, results suggest that DSB firms are more likely to manipulate earnings via REM, but not AEM. Additionally, we find that DSB firms engage in REM through cutting discretionary expenses, decreasing discretionary cash spending, and reducing the cost of goods sold through overproduction. We find some evidence that firms are more likely to increase REM when DSBs involve financial information or when firms delay the DSB disclosure or have low analyst coverage. We provide evidence that REM activities lead to lower subsequent performance in DSB firms.

What Phishing E-mails Reveal: An Exploratory Analysis of Phishing Attempts Using Text Analysis
Authors: O'Leary Daniel E.
Published: July 2019

Accountants and auditing firms are frequent phishing targets because of the proximity to organizational resources. Since phishing typically is done using emails, text analysis is used to explore differences between phishing e gmails and other emails. By analyzing and comparing a database of phishing messages to a database of the Enron emails, we find that the phishing data is statistically significantly different across a large number of univariate text variable categories. Further, we generate a model of phishing as “power,” based on independent variables of friend (who they pretend to be), achievement (of their goal), (to take your) money, and (typically done at) work. These variables are used as a basis to estimate power in both the phishing and non-phishing messages, where we find differences on the signs of the independent variables. Finally, using text analysis, we examine the ability of neural network models to differentiate between phishing emails and Enron emails.
Utilizing Blockchain and Smart Contracts to Enable Audit 4.0: From the Perspective of Accountability Audit of Air Pollution Control in China
Authors: Dai Jun , He Na , Yu Haizong
Published: July 2019

Industry 4.0 uses many technologies, such as smart sensors and IoT, to fundamentally improve manufacturing processes. These advanced tools can also be utilized by auditors for the purpose of achieving real-time auditing and monitoring, pushing the profession toward a new generation: “Audit 4.0.” Blockchains and smart contracts should be utilized to overcome new challenges in the transformation toward Audit 4.0. This paper explores the potential of blockchain and smart contracts to reengineer current audit procedures, thereby enabling Audit 4.0. First, this paper demonstrates a framework that summarizes where blockchain and smart contracts should be applied to help implement Audit 4.0. Then, it designs and implements a system to facilitate accountability audit for Chinese government officials regarding air pollution control. In this case, real air quality data are collected via crowdsourcing, verified and analyzed by blockchain and smart contracts to achieve a continuous audit of government officials' performance on air protection.
Heaping of Executive Compensation
Authors: Jorgensen Bjorn N. , Patrick Paige H. , Soderstrom Naomi S.
Published: July 2019

We investigate whether compensation grants are subject to “heaping,” the tendency of less informed individuals to provide round values when reporting estimates of discrete data. We document that an unexpectedly large number of CEOs receive round compensation (i.e., evenly divisible by 100,000 and/or 10,000). We investigate whether, consistent with heaping, the frequency of round compensation varies with proxies for boards of directors' effort in setting compensation. We find that round compensation is more common when boards have characteristics suggesting they provide weak oversight of compensation and thus face more uncertainty in estimating compensation. We also find less frequent round compensation when boards face stronger pressure from external stakeholders, encouraging boards to expend additional cognitive effort in setting compensation. Further, consistent with weak oversight of compensation, round compensation tends to be higher than non-round compensation. However, we do not find a consistent association between this higher, round compensation and future firm performance.

Performance Incentives, Divergent Thinking Training, and Creative Problem Solving
Authors: Huo Kun
Published: July 2019

Creativity theory suggests that effective solutions to creative problems depend on both divergent and convergent thinking (Cropley 2006). Using an experiment in which participants solve insight problems, I investigate the effect of incentive schemes on creative problem-solving performance. I find that both piece-rate pay and a flat wage plus public recognition generate higher performance with divergent thinking training than without. Consistent with the idea that incentives may promote more convergent thinking than divergent thinking, piece-rate pay generates lower creative problem-solving performance than the flat wage in the absence of divergent thinking training (flat wage plus recognition has a neutral effect). The study suggests that when employee performance depends on creative problem solving, firms should implement incentive schemes and/or control systems that promote both divergent and convergent thinking.

Методы измерения концентрации ДНК: совпадение относительных величин и различия абсолютных
Authors: Балановский О. П. , Кагазежева Ж. А. , Олькова М. В.
Published: July 2019

Измерение концентрации ДНК является базовым методом, от надежности которого зависит эффективность дальнейшего хранения и использования образцов. Существует несколько широко распространенных и хорошо зарекомендовавших себя способов измерения концентрации ДНК, однако степень их согласованности друг с другом изучена недостаточно. Целью работы было измерить концентрации одних и тех же образцов разными методами и провести сравнительный анализ полученных результатов. В двух независимых экспериментах, суммарно включивших 100 образцов геномной ДНК, сравнивали три метода определения концентрации ДНК: спектрофотометрический (Nanodrop), флуориметрический (Qubit) и ПЦР в реальном времени (Quantifiler). Выявлено, что значения концентрации ДНК, полученные разными методами, хорошо коррелируют друг с другом (коэффициенты корреляции составляют 0,98–0,99). Однако при такой отличной корреляции относительных величин концентрации абсолютные величины, полученные разными методами, варьируют значительно, вплоть до двукратных различий. Спектрофотометрический метод дает наиболее высокие концентрации, ПЦР в реальном времени — промежуточные, а флуориметрический — наиболее низкие. Различия в результатах более выражены для образцов с низкой концентрацией. Мы рекомендуем учитывать наличие этих систематических различий между результатами измерения концентрации ДНК, полученными разными методами.

About some Effects of Voltage Distortion on End User’s Equipment
Authors: M. Buzdugan
Published: July 2019

The main objective of the paper is to assess the influence of supply voltage distortions, especially voltage harmonics on end user’s equipment. Generally, harmonics are probably the most important issue of power quality, greatly influencing power flow. In the introductory section, the main definitions of power quality and the main methods of harmonic analysis, namely Fourier series, Fourier transform and Wavelet transform. The second section, devoted to experimental results, presents a series of measurements carried out for a setup composed of a programmable source supplying an induction motor, as end user equipment. The motor is supplied successively with three types of voltages, a clean sinusoidal voltage and two distorted ones, namely a 50% clipped voltage and a square voltage, synthesized according their harmonic content, and downloaded to a programmable supply source. The latest two waveforms are not arbitrarily chosen, being often encountered in practice, especially when the equipment is supplied through UPS’s or power converters. The load torque of the motor was adjusted by a controlled electromagnetic powder brake. Concluding, it can be said that distorted supply voltages, having an important harmonics content, highly affect the equipment operation, especially in terms of efficiency.
Impact of Short-Circuit Impedance Model for Variable-Speed Wind Turbine Generators on Operation of Overcurrent Relays
Authors: L. Somi  , B. Polajžer  , G. Štumberger
Published: July 2019

This paper discussed different short-circuit impedance models for type 3 and type 4 wind turbine generators. IEC and IEEE-PES models are either simplified or they require additional data. The proposed model is given by a non-linear dependency of the short-circuit impedance and voltage on the medium voltage side of the unit transformer. Furthermore, the proposed model, as well as the constant impedance-based model were used for timing coordination of overcurrent relays in a radial 6-bus network. The obtained results show that the constant impedance-based model overestimates short-circuit currents. Consequently, selectivity of individual overcurrent relays might be questionable.
A Double Stage DC/DC Converter for LED Lighting Automotive Systems
Authors: Marco Failla  , Gianpaolo Vitale
Published: July 2019

In this paper a DC/DC converter, conceived to be employed for LED lighting in automotive application, is proposed. It is composed of two stages to fit both to the constraint to be powered by a variable supply voltage and to deliver a constant output load current with reduced ripple to supply the LED. Firstly the LED has been experimentally characterized to obtain a model to be implemented on a circuit simulator. Then the design of the converter has been carried out, including the control laws, to verify the compliance with the constraints. Finally, a circuit based on commercial devices is proposed to be applied both to lighting and to direction indicators light, including current and temperature protection. Results, given in simulation, show good performance achievable with a low-cost hardware.
Viability of Distributed Generation with Biogas and Photovoltaic in an Isolated System
Authors: Effrain Roney Bernardes  , José Roberto Camacho
Published: July 2019

In the 1970s, the Brazilian oil crisis sparked interest in researching inexhaustible sources of energy. Within these sources of energy, those known as clean and abundant have become a viable alternative, reducing the pollutant capacity of waste, because the gas emitted by them in the decomposition that would previously go to the environment, is now destined for energy production and solid portion used as organic fertilizer [5]. This work aims to implement a case study to estimate the economic viability of the project, hybrid sources, in rural areas. The project in question will be analysed through software and mathematical methods, guaranteeing results close to those calculated analytically, compared to the energy sources studied as well as their feasibility and profitability through isolated distributed generation, which can bring fast and safe returns, such as a return of 84.37% biogas and 77.76% for photovoltaic compared to the initial investment over 25 years. Currently, Brazil suffers from a shortage of rainfall and consequently, with problems in the energy matrix, since the majority of Brazilian electricity comes from a hydroelectric power plant. Therefore, the purpose of this study is to present a solution and consequently self-sufficiency in rural areas, taking advantage of biodigesters and abundant sun to produce electricity.
Damage diagnosis for offshore fixed wind turbines
Authors: D. Agis  , Y. Vidal  , F. Pozo
Published: July 2019

This paper proposes a damage diagnosis strategy to detect and classify different type of damages in a laboratory offshore-fixed wind turbine model. The proposed method combines an accelerometer sensor network attached to the structure with a conceived algorithm based on principal component analysis (PCA) with quadratic discriminant analysis (QDA). The paradigm of structural health monitoring can be undertaken as a pattern recognition problem (comparison between the data collected from the healthy structure and the current structure to diagnose given a known excitation). However, in this work, as the strategy is designed for wind turbines, only the output data from the sensors is used but the excitation is assumed unknown (as in reality is provided by the wind). The proposed methodology is tested in an experimental labo ratory tower modeling an offshore-fixed jacked-type wind turbine. The obtained results show the reliability of the proposed approach.

Published: July 2019

Horizontal tidal turbine presents important similarities to the wind turbine power systems. Therefore, it would be useful to exploit this similarity to study this important source of energy. In this paper, a new concept of a hybrid offshore wind tidal power generation systems coupled electromechanically is studied. Furthermore, a 'time virtual' approach is also presented in order to investigate and compare the energy potentials for given tidal and wind sites. Both the new concept of coupling and virtual time method are simulated in Matlab/Simulink and applyied on Real Time Emulator. Obtained results are presented and disscussed.

Through the MG, the consumer may set up its own business with a the sale of its own energy, thus, the Automation and Electrical Systems Simulation Laboratory (LASSE) is interested in participating of the MG market. Creating and/or innovating a business requires knowledge of the application environment. This reality has as consequence the determination of strategies for the company’s management in the vision of the market dynamics. This research aims to define the necessary requirements for the performance of LASSE in the MG environment and to develop the systemic LASSE diagram associating the structural elements of the business model with the characteristics of LASSE. The information was generated through the Business Model Generation (BMG) methodology, among which the Business Model Canvas tools stand out. The research interests LASSE for creating ideological guidelines for members of the LASSE Smart Energy Project. In this way, it is possible to clearly understand the process of introduction to the MG environment, as well as the necessary characteristics for the elaboration of Business Models (BM).
Harmonics and Flicker in an Iron and Steel Industry with AC arc furnaces
Authors: M. Pérez-Donsión  , S. Jar Pereira  , F. T. Oliveira
Published: July 2019

An AC arc furnace is an unbalanced, non-linear and time-varying load, which can cause many power quality problems to the electric network inside the plant and in its electrical vicinity. Although different studies addressing harmonics and flicker analyses on arc furnaces can be found in the bibliography, it is very difficult obtain an exact model that considers all the parameters that influence the process, and therefore it is necessary to obtain actual measurements under different conditions. This paper presents measurement results for harmonic distortion, flicker and unbalance obtained over three different measurement campaigns on an iron and steel industry (SNL), as well as the pertinent conclusions. Measurement campaigns were performed on an AC arc furnace of 83 MW (170 TM) with a 120 MVA transformer connected by a ‘dirty’ 220 kV line (55 km) to the Substation of Carregado, where other feeders supply industrial and domestic consumers. Finally, the dynamic behaviour of an SVC will be analysed and compared to that of a STATCOM by means of simulation studies.

Is there any example of an isolated system in nature? What is the applicability of the second law of thermodynamics?
Authors: Oliveira, L. E.
Published: July 2019

In 1854, Rudolf Clausius developed the second law of thermodynamics, which measures the disorder of a system under investigation. According to that law, all isolated systems always increase in entropy over time. This conclusion was emerged by an empirical experiment of a confined gas that is released inside a vessel. The gas will always expand, thus increasing the entropy of the system. However, the question that remains is that if there is any isolated system in the Universe? This law is bringing several mistaken conclusions such as many examples showed by experts in this area. The purpose of this paper is to show misleading examples shown by the scientific authorities of the second law of thermodynamics. Despite the second law, the Universe has always produced more organized and complex systems over time. Actually, is impractical to show examples of the second law of thermodynamics because there is no isolated system throughout the Universe. The 13.7 billion year history of the Universe's existence shows that it evolves from a hot soup of energy and matter to complex systems like stars, planets, and living things.
Numerical Experimental Validation of a Proposed MPPT Algorithm with Dynamic Hysteresis for PV Systems
Authors: Nubia Ilia Ponce de Le´ on Puig  , Leonardo Acho  , Jos´ e Rodellar
Published: July 2019

In the last decades, the renewable energies have had a highly positive effect on the daily life. This due to the necessity of reducing the common fuel energies that have negatively impacted the environment. Among all the available renewable energies, the solar energy is one of the most common. This energy is obtained through Photovoltaic (PV) systems. Thus, in previous years, new techniques of Maximum Power Point Tracking (MPPT) to raise the quality of the energy provided by PV panels have been proposed. Since the energy provided by the PV cells depends on the external environmental conditions, as temperature or sun irradiance, the MPPT methods should be adequate to deal with these external changes by maintaining the desired power level. Hence, this paper proposes a recent hysteretic dynamic technique to extract the maximum power from a PV panel array by employing a Boost DC/DC converter to supply energy to an inductive load. Here, a comparative study between the results obtained with the well known Perturb and Observer (P&O) algorithm and by using our dynamic hysteretic MPPT method is analyzed, specifically when the PV panel is submitted to fast variations in temperature and irradiance. It will be proved through numerical experiments realized in MatLab/Simulink that our hysteretic MPPT algorithm provides a better achievement of the maximum power of the PV panel in comparison to the conventional Perturb and Observer method.

Iwi radio in the era of media convergence: The opportunities and challenges of becoming ‘more than radio.’
Authors: McEwan Rufus
Published: July 2019

Operating for the past 30 years, New Zealand’s 'iwi radio' stations broadcast a mixture of te reo Māori and English language programming throughout the country. The 21 stations that presently operate were established as a strategy to improve upon the severe decline in the indigenous language. As radio stations, each initiative also affords individual Māori groups some autonomy in the mediated protection and promotion of indigenous identity. Collectively represented by Te Whakaruruhau o Ngā Reo Irirangi Māori, the iwi stations stand apart from the highly-consolidated mainstream commercial and public service sectors, but are now similarly confronted with the challenge of a rapidly changing media landscape. Utilising convergence as a prominent, albeit contentious, descriptor of media transformation, this article analyses the response of the iwi radio sector to convergence processes. Initiatives that include the integration of web and social media and the establishment of a networked switching platform to share iwi content highlight parallel opportunities and challenges for the iwi radio stations as they strive to become ‘more than radio’ on limited resourcing. This discussion highlights the experiences of radio practitioners tasked with the preservation and progress of indigenous voices in an era of convergence, providing further contextual insight into contemporary accounts of media transformation, radio and Māori media.

Authors: Tarai Jope
Published: July 2019

Political campaigning on social media in Fiji was first witnessed in the 2014 national election. In the Fiji 2018 general election, social media political campaigning had evolved with greater complexity and a wider variety of implications. This research examines and highlights the use of social media by political parties and candidates in the 2018 national elections. This examination provides comparative social media discussions between the two elections; 2014 and 2018. The research uses digital ethnography as a methodology to examine and highlight social media use, by political parties and candidates in Fiji’s 2018 national elections. The research found that FijiFirst, as the ruling government, had significant advantage in Fiji’s social media landscape. However, opposition social media efforts and growing Facebook ‘reactions’ were beginning to challenge FijiFirst’s social media dominance.
Fiji’s coup culture: Rediscovering a voice at the ballot box
Authors: Krishnamurthi Sri
Published: July 2019

Commentary: The second Fiji General Election in 12 years, since the fourth coup in 2006, took place on 14 November 2018, and once again the key players were the three parties that gained seats in Parliament in the 2014 election. The three parties: FijiFirst, the incumbent government led by the 2006 coup leader Voreqe Bainimarama; the preeminent opposition, Social Democratic Liberal Party (SODELPA), whose leader was the instigator of the first two coups, Sitiveni Rabuka; and the National Federation Party (NFP) which was led by former University of the South Pacific economics academic Professor Biman Prasad. The 2018 election was widely seen as another sign of progress for Fiji’s fragile democracy and both the significant protagonists were former military commanders and coup leaders seemingly committed to democracy. The media remained cowed, a legacy of the 2010 Media Industry Development Decree (MIDD, 2010), giving rise to using other forms of media such as social media platforms, with Facebook being the most popular. This commentary reflects on the experience of a journalist on a postgraduate assignment to report on the 2018 election.

Implicit Learning of a Person in the Face of Comprehensive Dynamic Problems
Authors:   Samara National Research University, Kryukov Sergey Viktorovich
Published: July 2019

Establishing the conditions and patterns of implicit learning, identifying the determinants of this process are of considerable interest to researchers at the present stage of cognitive science development. The solution of comprehensive dynamic problems is a model of interaction with complex dynamic systems (political, economic ones). A person always interacts with such systems. To solve the tasks effectively, he/she should increase knowledge about the processes of cognitive activity. The study discusses the emergence of implicit knowledge when interacting with complex dynamic systems. The author analyzes the scientific and psychological literature (both Russian and international) to comprehend the research experience of implicit learning, search for conditions and determinants of an effective solution to complex dynamic problems based on personal characteristics and cognitive style of the subjects. It is assumed that implicit knowledge is a part of any cognitive activity. The study of this phenomenon has both theoretical and practical significance.

Authors:   Sevastopol State University, Khitushchenko Vitalina Valeryevna
Published: July 2019

Although extensive research has been carried out on the educational experiment, there is no ambiguous and generally accepted view on its methodological basis and the ways to do it effectively in modern education science and practice. In this regard, the purpose of the study is to test the hypothesis and extend the range of experiment techniques (and their combinations). The author conducts the educational experiment to identify the initial level of English proficiency in general and digital English proficiency in particular in students of Philology and other Departments in several universities. In the context of this experiment, the concept of digital proficiency is regarded as a subset of the overall assessment of the level of English proficiency. The research findings can form the basis for recommendations to develop student engagement with educational content and demonstrate that e-learning courses are a factor in improving students’ academic performance in English.
A Sociological Study of the Views of Primorsky Krai Population on High-Tech Medical Care
Authors:   Far Eastern Federal University, Syroed Nadezhda Savvovna , Bakushkina Natalia Evgenyevna ,   Far Eastern Federal University
Published: July 2019

The paper outlines the results of a pilot sociological study on the ideas of Primorsky Krai population about high-tech medical care (HTMC). In the authors’ opinion, to increase its accessibility for Russian people is one of the priorities of the national Health Project. The lack of citizens’ awareness of HTMC services for the treatment of complex diseases at the expense of the Federal Compulsory Medical Insurance Fund is a factor that reduces the level of availability of HTMC for the subjective reasons. More than half of respondents involved in the survey find it difficult to explain the meaning of the term ‘high-tech medical care’. A significant number of interviewees state that high-tech care is unavailable to most residents. A third of respondents believe that HTMC is a fee-based service. This assumption is not true because the Federal Compulsory Medical Insurance Fund provides HTMC treatment based on quotas for free. The research findings confirm the hypothesis about a low awareness of Primorsky Krai population of this type of care and the right to free HTMC.
Tamaño óptimo de parcela e incidencia de la podredumbre blanca del capítulo del girasol en el sudeste bonaerense
Authors: Dinon M. Anabella , Delgado Santiago , Castaño Fernando
Published: July 2019

Para conocer el tamaño de parcela que permita medir con eficiencia la incidencia de la Podredumbre blanca del capítulo-PBC de girasol (Helianthus annuus L.) se evaluó, en Balcarce, un par de híbridos en ensayos de uniformidad durante 2016 y 2017. Todos los capítulos de cada ensayo se inocularon con Sclerotinia sclerotiorum (Lib.) de Bary. Durante el primer año y para cada híbrido, se delinearon 165 parcelas mínimas, de un surco de 2m x 0,70m (=1,4m2). Mientras que en el segundo, la cantidad fue de 150. En cada una de esas parcelas básicas se registró la incidencia de PBC. Luego se generaron ocho tamaños más, combinando las parcelas mínimas adyacentes en distintos arreglos. El tamaño óptimo se señaló detectando el punto de máxima curvatura en gráficos que relacionaron el coeficiente de variación y los nueve tamaños de parcelas considerados. El análisis de varianza combinado sólo detectó efectos significativos de híbridos (H), años (A) y HxA sobre la incidencia de PBC. Los resultados obtenidos no permitieron señalar un único tamaño de parcela, dado que el óptimo dependió del nivel de resistencia del híbrido y del año de experimento. Así durante 2017, año más favorable a la enfermedad, el tamaño óptimo de parcela para los dos híbridos, resultó inferior que el señalado en 2016. Bajo las condiciones en que se desarrolló el experimento, el uso de parcelas de mayor superficie al señalado, no provocaría un incremento significativo en la fiabilidad de medición de la INC, por unidad de recursos utilizados.

Foi realizado estudo para descrever a partição da energia e produção de metano por ovinos alimentados com fenos do capim Andropogon gayanus colhidos aos 56, 84 e 112 dias de crescimento. Utilizou-se a metodologia da calorimetria indireta para mensuração das perdas de energia e para a determinação da energia digestível (ED), metabolizável (EM) e líquida (EL). O delineamento experimental foi inteiramente casualizado, sendo constituído de três tratamentos e seis repetições. As médias foram comparadas pelo teste Studant-Newman-Keuls (SNK) ao nível de 5% de significância. O feno, cujo material foi colhido aos 56 dias, resultou em maior (P<0,05) consumo de energia digestível (CED) em relação aos materiais fenados com 84 e 112 dias de rebrote. As perdas diárias de energia através da urina, do metano e do incremento calórico não apresentaram diferença (P>0,05) entre os tratamentos. O feno contendo material colhido aos 56 dias apresentou valor de digestibilidade aparente da energia bruta (DAEB) superior (P<0,5) aos demais tratamentos que não diferiram (P>0,05) entre si. O feno colhido as 56 dias apresentou maior valor de energia digestível e energia metabolizavél em relação aos demais fenos que não diferiram entre si (P>0,05). A produção de metano não variou (P>0,05) entre os tratamentos estudados.

El hecho histórico es la entrevista del papa León Magno y Atila en el año 452, cuyo resultado fue que los hunos se retiran del valle del Po, con el consiguiente alivio para ltalia. El hecho pronto se interpretó como providencial y la tradición medieval lo atribuyó exclusivamente a la entrevista y a un milagro protagonizado por san Pedro y san Pablo. El proceso de transmisión del relato tuvo una expresión verdaderamente relevante en el conocido fresco de Rafael de las Estancias del Vaticano. En el trabajo se hace una revision selectiva de los hitos mas significativos en la tradición historiográfica y hagiográfica. Y dentro de ella se indica el texto concreto que ha servido de fuente a Rafael, frente a apreciaciones erróneas o generalizadoras de la critica antigua y moderna.

Rozaduras. Algo sobre rueda
Authors: Martínez Silvente María Jesús
Published: July 2019

Cada cual busca -y no siempre encuentra- la mejor manera de expresar sus sentimientos, la vía adecuada, el vehículo que le permita compartir matices de una realidad individual. Jorge Rueda lo hace mediante la fotografía, o mejor dicho, mediante el medio fotográfico, manipulando conscientemente sus orígenes hasta conseguir el resultado que persigue, la fórmula que nos hace conocer esbozos de su disconformidad, de sus desavenencias, discordias y divergencias, rozando libertades que nos pertenecen, pero que raramente logran salir a la luz.

En 1546, el historiador y filósofo Benedetto Varchi pronunciaba en la Academia de Florencia sus conocidas Due lezioni ... nella prima del/e quali si dichiara un sonetto di M. Michelagnolo Buonarroti .. Nella seconda si disputa qua/e sia piú nobile arte la Scultura, o la Pittura, con una lettera désso Michelagnolo, & piú altri eccellentiss. pittori, et scultori, sopra la quistione sopradetta. No pasaron muchos años para que sus palabras fueran dadas a la letra impresa, de tal forma que, ya en 1549, aparecía la primera edición con prefacio del texto varchiano.
Hernández Martínez, Ascensión: Documentos para la historia de la restauración
Authors: Ordóñez Vergara Javier
Published: July 2019

En el ámbito de las ciencias humanas, cualquier disciplina exige contar con un conjunto básico de instrumentos teórico-metodológicos sobre los que levantarse y seguir construyéndose. Tan necesario como ello, y como la actualización que de sus fundamentos es preciso hacer constantemente para que éstos permanezcan hábiles, son las reflexiones críticas que glosen el sentido de aquellos postulados primeros y de los que han sido elaborados a lo largo del tiempo, para así interpretar el contexto del que son fruto y en el que alcanzan su justificación.

Rodríguez Marín, Francisco José: Málaga conventual. Estudio Histórico, Artístico y Urbanístico de los Conventos Malagueños
Authors: Camacho Martínez Rosario
Published: July 2019

La actual ciudad de Málaga, capital de una zona turística por excelencia, por fortuna ha comprendido, quizá un poco tarde, que era necesario mantener en su centro histórico la imagen de la ciudad burguesa decimonónica que, dotada de un equipamiento acorde con el progreso y el desarrollo económico que vivió en función del despegue comercial e industrial, surgió tras un proceso radical de reforma interior, después de la desamortización de los bienes eclesiásticos, sobre los solares de los antiguos conventos malagueños.
Being “completely half afraid to think”: Confronting the Absurd in Flann O’Brien’sThe Third Policeman
Authors: Duleba Maxim
Published: July 2019

In order to demonstrate an aspect in which the novel is relatable to the canon of absurdism and enrich the view of dimensions in which it functions, the purpose of the following article is a reading of Flann O’Brien’sThe Third Policemanin relation to the Absurd as an ontological category of existentialism and absurdism. Firstly, some assumptions already made on account of the novel are introduced. Secondly, the relevant and chosen characteristics of the Absurd are summarized in relation to Kierkegaard’s and Camus’s conceptions of the Absurd. Then, the novel is interpreted in relation to the insufficiency of human knowledge and rational thought in terms of achieving comprehension transcending existence. Lastly, the novel is interpreted in relation to the narrator’s fear of death, with death as an element transcending existence and adding to its irrationality. Overall, the way in which the novel depicts a specific contraction resulting in the Absurd is illustrated.

Authors: Tasak E. , Ziewiec A. , Zielińska-Lipiec A. , Ziewiec K.
Published: July 2019

There is a problem in obtaining a suitable impact strength of the padding weld after cladding with a martensitic filler metal. Too low annealing temperature below 580°C and the excessive annealing temperature above 650°C do not provide adequate impact strength of the padding weld. A heat treatment technology for mixed joints has been developed based on the results of the microscopic observations, X-ray diffraction measurements and transmission electron microscope examination. The problem was identified and a special technology of heat treatment for the dissimilar joint was elaborated. This technology provides a high impact resistance of the padding weld and an appropriate properties of the base material.

Authors: Buszko M. H. , Krella A. K.
Published: July 2019

The degradation of materials due to slurry erosion is the serious problem which occurs in the power industries. The paper presents actual knowledge about an influence of individual factors connected with flow conditions, particles and material properties on the slurry erosion resistance. Among the factors connected with operating conditions, an influence of impact angle, and velocity of impact, particle concertation and liquid temperature have been described. In case of the factors connected with solid particle properties, an influence of the size, shape and hardness have been discussed. In the part devoted to the impact of material properties, due to different types of materials, the issues of resistance to erosion of slurries related to the properties of steel, ceramics and polymers are discussed separately. In the paper has been shown that a change of any of mentioned factors causes a change in the erosion rate due to the synergistic effects that accompany to slurry degradation.
The Influence of Pulsating Tensile Stress on Residual Magnetic Field of P91 Steel Samples
Authors: Złocki A. , Roskosz M. , Kwaśniewski J.
Published: July 2019

Measurements of Residual Magnetic Field RMF (the tangential component parallel to the load direction) were taken on the surface of P91 steel plate samples (X10CrMoVNb9-1) subjected to periodic pulsating tensile cyclic loads with the use of flux-gate and magneto impedance sensors, and preliminary measurement results are compiled and analyzed. The study investigates how the microstructure and load cycle parameters affect the RMF changes due to stress variations. Each combination of parameters: microstructure and load cycle corresponds to the characteristic variability pattern of magnetization and its maximum and minimum values.
