Published: February 2019

Na última década, a Internet das Coisas (IoT) e Deep Learning receberam significativa atenção da indústria, bem como das universidades e dos centros de pesquisa. As principais razões por trás desse interesse está no fato que IoT permite conectar diversos dispositivos ao nosso redor por meio da Internet - criando ambientes inteligentes - e Deep Learning mostrou-se ter bons resultados em uma série de aplicações, em comparação com as abordagens tradicionais, principalmente, na classificação de imagens. Neste trabalho realizamos um mapeamento sistemático de literatura com o objetivo de identificar como IoT e Deep Learning podem funcionar conjuntamente em diversos sistemas e aplicações. Os resultados apontaram que a união dessas duas abordagens é útil para a solução de vários problemas práticos.
Long-Run Career Consequences for Andersen's Putative Partners
Authors: Sellers R. Drew , Fogarty Timothy J.
Published: February 2019

The sudden collapse of Arthur Andersen & Co. (Andersen) in 2001–2002 altered the careers of many professionals who were employed by that international accounting firm. Now that many years have passed since that event, some long-run consequences can be quantified. This paper examines the subsequent careers of 267 managers employed by Andersen at that time in seven Midwestern U.S. cities. Benchmarking these results against similarly situated individuals at another large firm, we conclude that ex-Andersen managers were much less likely to continue in large firm employment, stay in public accounting, or achieve partnership status in the profession. However, the professional networks maintained by ex-Andersen people many years after that firm's collapse appear as strong as that of the control sample.

Conservatism in Accounting: A Reassessment
Authors: Bloom Robert
Published: February 2019

This paper examines how the concept of “conservatism” evolved in historical and contemporary accounting writings using authoritative professional and academic documents. The paper reviews the application of conservatism in the FASB and IASB conceptual frameworks. A brief discussion of empirical research on conservatism is provided. Finally, the paper looks at the declining influence of conservatism in private company accounting principles in three selected countries: Belgium, Switzerland, and Japan. Conservatism is found to be a perennial issue in accounting practice and accounting standard setting. This concept has long been embedded in private company accounting in different countries. Its rationale, along with its conflict with neutrality have been debated for centuries.
Managing Festivals in a Digital World
Authors: Diaz Kristy
Published: February 2019

What exactly is digital? Debated by those who are less tech-savvy and those with advanced knowledge alike, the term ‘digital’ has been notoriously difficult to define. We see it used mostly as a prefix – digital device, digital television, digital divide – but, for the purposes of this book when we say ‘digital’ we are referring to the use of digital technology and communications. This chapter focuses on giving you an understanding of how digital technology and communications are used in festival management, and how you can use them to maximise the success and impact of your festival. So why is digital technology so important? Before looking at the practicalities, it is worth looking briefly at how it has developed and has had a fundamental and mostly liberating impact on both marketing and human communications.
Digital technology has had an impact on arts and culture in the following ways: mass communications, access, rights and ownership (copyright) and networking, power and control.
Managing Human Resources
Authors: Jordan Jennie
Published: February 2019

It used to be called ‘personnel’, or ‘personnel management’, and now has the title ‘human resources management’, usually shortened to HRM. Within large organisations it can be the least visible until people problems arise. It has to undertake the dull but vitally necessary tasks of ensuring that an organisation’s ‘people management’ complies with the law and that the company gets the best out of the people it employs. So, what’s this got to do with the comparatively small, lively, friendly, funky, chaotic world of festivals? No matter how small and cuddly your festival is, the management of people, whether full time or very occasional, will be crucial to your success. This chapter sets out the principles which will increasingly apply as your festival develops and grows.
Research and Evaluation
Authors: Newbold Chris
Published: February 2019

In this chapter we will demonstrate that research is at the heart of good festival management. Good festival management involves informed decision making, and research methodologies support this at all levels from planning and programming, through the marketing and the running of the festival, to event evaluation and audience development. Research is a key element of the iterative process through which festivals develop year on year via experience and feedback, not only from audiences, but also from artists, staff and volunteers; this information then feeds into the successful planning of the next event and so on and so forth. The aims of this chapter are to introduce the research process as a whole, give advice and encouragement, discuss the key considerations in carrying out successful research, and identify and describe the main research methods that managers will encounter in running and evaluating their festival. Whilst we will focus on the most often used methodologies of questionnaires, interviews, focus groups and observation, we will also offer some other complementary approaches and discuss the use of digital and online resources in festival research. Carrying out research is all about making the right decisions. Each method has its advantages and disadvantages, and research can be time-consuming and expensive; this chapter will help you to make the right decisions about the methodologies and their use. Successful research is all about juggling a number of key factors such as cost, time, sample size, response rates and reliability. Research does not have to be either costly or time consuming – indeed a great deal of what festival managers already do could be considered as research, and this chapter will help them sharpen up some of those practices.
Social Impact Assessment
Authors: Getz Donald
Published: February 2019

Social and cultural change can occur slowly, sometimes invisibly, and in many directions at once. It will usually be difficult to differentiate the changes caused or influenced by events and tourism from wider forces and trends in society. The approach taken in this chapter is to first define social impacts and social impact assessment, then examine the wide range of social impacts that could be the subjects of SIA. A series of figures presents types of social impacts that should be considered for the major subjects of IA, starting with individuals and ending with whole societies. In each of these tables there are suggested goals, methods and indicators. Specific types of social impact are expressed as goal statements, mostly benefits to achieve. The SIA process is then discussed, including methods of particular relevance to SIA for events and tourism. Special attention is given to the concept of social capital and how it can be assessed. Not only is social capital an important topic in the literature and apparently of interest to many policy makers, but exploring how to measure this concept is indicative of the challenges related to other social and cultural theories and concepts. Refer back to Chapter 3 for a parallel discussion of how to construct a theory of change model for social integration and inclusion. For related history and topical overviews, readers are encouraged to consult books that give the big picture, including Exploring the Social Impacts of Events, edited by Richards et al. (2013), and Event Studies by Getz and Page (3d. ed., 2016).
Cultural Impacts
Authors: Getz Donald
Published: February 2019

Cultural impact assessment (CIA) is often combined with social impacts, but there are often very good reasons for a separate approach. CIA is especially relevant for festivals and cultural celebrations, and any event featuring ethnic, indigenous and multicultural themes, or events and tourism located in sensitive cultural communities. This chapter starts with definitions of culture and its elements, leading to an overview of the main related themes found in the tourism and event literature. A set of goals, related methods and key impact indicators is presented as a way to begin thinking about cultural impact assessment. The process and methods of CIA is then detailed, incorporating concepts and methods from earlier chapters.
Generic Stakeholder Management Strategies
Authors: Niekerk Mathilda van , Getz Donald
Published: February 2019

A continuous planning process for stakeholder management is described. To get started, and even for organizations already engaged with stakeholders, a set of questions is provided concerning internal and external stakeholders. A SWOT analysis might help, looking at the strengths, weaknesses, opportunities and threats attached to each stakeholder or type of stakeholder. A third planning technique is stakeholder mapping, described for both internal and external use. A number of generic approaches to formulating strategy are reviewed, and they each take a somewhat different approach to classifying stakeholders and identifying appropriate strategies for managing relationships. From these we have provided a blended strategy matrix, but users will have to settle on their own approach appropriate to their circumstances.

Con el objetivo de analizar la contabilidad como plataforma de gestión del talento humano en las organizaciones empresariales, se realiza una investigación documental con diseño bibliográfico, soportada por la revisión en profundidad de cada una de las categorías, así como unidades de análisis del tema seleccionado, lo cual permite la recolección de información de distintas fuentes, sobre una muestra constituida por elementos de referencia teórica. Para luego extraer a través de una matriz previamente formulada la información examinada, conformada por aspectos que soportan implícita o explícitamente las conceptualizaciones de contabilidad, finanzas, activos intangibles, gestión del talento humano, gestión del conocimiento, capital intelectual y métodos para medirlo, así como organizaciones empresariales. Concluyendo que la contabilidad está articulada y guarda correspondencia con la gestión del talento humano de cualquier organización, por lo tanto de manera efectiva requiere involucrar en sus procesos la medición del capital intelectual generado, como parte de los eventos económicos acometidos en un momento determinado. En este sentido, en la investigación fue viable explorar los diferentes métodos utilizados para el reconocimiento de estos activos intangibles, como parte de la funcionabilidad de la empresa, considerando que los cambios ocurridos en la economía mundial, llevan a sostener la condición del conocimiento como un elemento fundamental de la escena económica global, en consecuencia no resulta extraño, ni algo ajeno al desenvolvimiento organizacional, que los diferentes niveles contables de las empresas se encuentren interesados en controlar y gestionar el referido factor.
IMPROVING SERVICE QUALITY IN IPTV NETWORKS
Authors: Maltseva Natalia Sergeevna
Published: February 2019

Technical advances in recent years allow to transfer video over IP networks with acceptable quality. One of the main difficulties in providing services over IP networks is packet loss at the moments of mass channel switching and, as a result, deterioration in the quality of transmitted information. The research objective is improving the quality of service in IPTV networks, reliability of communication area due to the use of a redundant switching field with parallel configuration in IP switches, which provides load dividing for normal operation and avoids collapsing network under peak traffic. The block diagram and operation algorithm are given, which allows to increase the processing speed of the IPTV head station. Specific feature of load distribution is described by the fact that servicing one data flow can be provided by different information fields at different stages. There has been given a formalized model of parallel block switch. Today, modern switching systems do not allow tuning by parallel methods and combining the transfer of information with system tuning.
INFLUENCE OF INCONSTANT DISTRIBUTION OF DEADWOOD BEARING STIFFNESS COEFFICIENTON NATURAL FREQUENCY OF THE SHAFT TRANSVERSE VIBRATIONS
Authors: Kushner Guriy , Mamontov Victor Andreevich
Published: February 2019

One of the most significant factors affecting the natural frequency of transverse vibrations of shaft-slide bearing systems is the stiffness coefficient of the slide bearing. The need to consider the influence of heterogeneity of stiffness coefficient of the bearing on its natural frequency is caused by the fact that when the bearing is worn, the modulus of longitudinal elasticity of the material changes, and since the bearing wears unevenly, the non-uniform distribution of the stiffness coefficient occurs. The problem of determining the natural frequency of transverse vibrations of a ship propeller shaft based on the foundation with a variable stiffness coefficient along the length has been studied. The differential equation of the propeller shaft vibrations written taking into account the stiffness coefficient variable along the shaft length is considered. It has been noted that, in the general case, this equation is a fourth-order partial differential equation and cannot be integrated in quadratures for an arbitrary stiffness distribution function along the shaft length. A numerical-analytical method for determining the natural frequency of a system based on approximation of the stiffness distribution function by a piecewise-linear function is proposed. The method is applied to calculate the natural frequencies of the pipeline section taking into account the functions describing the change in the stiffness coefficient. The proposed method allows to consider the section of the shafting enclosed in the stern bearing, subject to the non-uniform distribution of the stiffness coefficient of the bearing, and is the basis for improving the accuracy of finding the true natural frequency of transverse vibrations of the shafting.

Pharmacokinetics after subcutaneous administration of a single dose of cefovecin sodium in African lions (Panthera leo)
Authors: Flaminio Kelly P. , Christensen John Mark , Alshahrani Sultan Mohammed , Mohammed Sumeia Mohammed
Published: February 2019

OBJECTIVE To determine the pharmacokinetics of cefovecin sodium after SC administration of a single dose to African lions (Panthera leo).

ANIMALS 3 adult (9 to 10 years old; 1 male and 2 females) and 3 juvenile (2 years old; 1 male and 2 females) African lions.

PROCEDURES A crossover study was conducted. A single dose of cefovecin was administered SC at 4 mg/kg (half dose) and 8 mg/kg (full dose) to African lions. Blood samples were collected daily for 14 days after cefovecin injection. Plasma drug concentrations were determined by use of high-performance liquid chromatography with UV detection.

RESULTS Cefovecin had first-order elimination kinetics for doses of 4 and 8 mg/kg. Mean ± SD maximum plasma concentration was 9.73 ± 1.01 μg/mL and 18.35 ± 0.94 μg/mL after doses of 4 and 8 mg/kg, respectively. Time to maximum plasma concentration was approximately 4 hours for both doses. Mean elimination half-life was approximately 111 and 115 hours after doses of 4 and 8 mg/kg, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE Cefovecin was detected in lion plasma for 336 hours after administration at both 4 and 8 mg/kg at concentrations greater than the reported minimum inhibitory concentration (0.06 μg/mL) for common bacterial organisms in domestic cats. These results indicated that cefovecin administered at 4 mg/kg SC reached therapeutic concentrations for an extended period in African lions.
Ex vivo computed tomography evaluation of loading position on morphometry of the caudal cervical intervertebral disk spaces of dogs
Authors: Knell Sebastian C. , Smolders Lucas A. , Steffen Thomas , Pozzi Antonio
Published: February 2019

OBJECTIVE To provide an objective, quantitative morphometric description of the caudal cervical intervertebral disk (IVD) spaces of dogs.

SAMPLE Vertebral specimens consisting of C4 through C7 from 5 medium-sized dogs.

PROCEDURES CT images were obtained with the specimens positioned in neutral, flexion, extension, and lateral bending positions. Size and shape of the cranial and caudal end plates, angle between the end plates (IVD wedge angle), and craniocaudal distance (IVD width) between end plates for the 4 loading positions were measured and compared for the 3 segments (C4-5, C5-6, and C6-7).

RESULTS End plate size and shape, IVD wedge angle, and IVD width were not significantly different among the 3 segments. Caudal cervical end plates were consistently larger than cranial cervical end plates. The IVD wedge angle ranged from −4.8° to 15.2°. Flexion induced a reduction in IVD width in the ventral portion of the IVD, whereas extension induced a decrease in width in the dorsal portion of the IVD. Central IVD width remained unchanged among the loading positions.

CONCLUSIONS AND CLINICAL RELEVANCE Unique morphometric and dynamic characteristics of the caudal cervical IVD space of dogs were detected. These findings may help investigators when designing IVD prostheses for dogs with cervical spondylomyelopathy.
Duration of β-adrenoceptor blockade associated with once-daily oral administration of atenolol in healthy dogs
Authors: Waterman Mari I. , Abbott Jonathan A. , De Rezende Andrea Eriksson , Wilcke Jeffrey R.
Published: February 2019

OBJECTIVE To test the hypothesis that once-daily oral administration of atenolol would attenuate the heart rate response to isoproterenol for 24 hours.

ANIMALS 20 healthy dogs.

PROCEDURES A double-blind randomized placebo-controlled crossover study was conducted. Dogs were assigned to receive atenolol (1 mg/kg, PO, q 24 h) or a placebo for 5 to 7 days. After a washout period of 7 days, dogs then received the other treatment. Heart rate at rest (HRr) and heart rate induced by administration of isoproterenol (HRi) as a constant rate infusion (0.2 μg/kg/min for 5 to 7 minutes) were obtained by use of ECG 0, 0.25, 3, 6, 12, 18, and 24 hours after administration of the final dose of atenolol or the placebo. A mixed-model ANOVA was used to evaluate effects of treatment, time after drug or placebo administration, treatment-by-time interaction, period, and sequence on HRr and HRi.

RESULTS Effects of sequence or period were not detected. There was a significant effect of treatment and the treatment-by-time interaction on HRi. Atenolol significantly attenuated HRi for 24 hours but did so maximally at 3 hours (least squares mean ± SE, 146 ± 5 beats/min and 208 ± 5 beats/min for atenolol and placebo, respectively). The effect at 24 hours was small (193 ± 5 beats/min and 206 ± 5 beats/min for atenolol and placebo, respectively). Atenolol had a small but significant effect on HRr.

CONCLUSIONS AND CLINICAL RELEVANCE This study of healthy dogs receiving atenolol supported a recommendation for a dosing interval < 24 hours.

OBJECTIVE To evaluate the effectiveness and safety of dipyrone to control pyrexia in horses with naturally occurring disease under field conditions.

ANIMALS 138 horses with pyrexia and various infections evaluated at 14 veterinary sites in 12 states.

PROCEDURES In the first (effectiveness) phase of this 2-phase study, horses were randomly assigned 3:1 to receive 1 dose of dipyrone (30 mg/kg [13.6 mg/lb], IV) or an equivalent amount of placebo. Effectiveness was defined as a decrease in rectal temperature ≥ 1.1°C (2°F), compared with the pretreatment value, or a rectal temperature of ≤ 38.3°C (101.0°F) 6 hours after treatment administration. Horses deemed to have an appropriate reduction in rectal temperature (regardless of treatment group) by 6 hours were immediately entered into the safety phase of the study, in which dipyrone was administered IV at 30 mg/kg between 0 and 8 times up to every 8 hours on an as-needed basis, as determined by the clinical investigators. Horses were monitored throughout for adverse events.

RESULTS A significantly greater proportion of dipyrone-treated horses (76/99 [77%]) had an effective treatment response than did placebo-treated horses (6/31 [19%]). Posttreatment adverse events were mild and transient. No differences in types or prevalence of gastrointestinal adverse events were evident between treatment groups.

CONCLUSIONS AND CLINICAL RELEVANCE Dipyrone was effective in controlling pyrexia by 6 hours after IV administration of a single 30-mg/kg dose in a large proportion of treated horses. Adverse effects were minimal.

Authors: Veresné Somosi Mariann , Varga Krisztina
Published: February 2019

The study defines a process-oriented framework for measuring social innovation. Social initiatives focus on meeting the needs of the community and solving their problems The local, community-based innovative ideas have a significant role. During the systematic operation of innovation, the starting point (expression of local needs) and the definition of short and long term goals as induction factors are involved in the innovation process. The starting conditions are widening in the transformation with incentive and inhibiting factors, while the stakeholders of the innovation process are also determined. As a result of the transformation, territorial-specific results will be created complementing the economic and / or social impact of the given innovation. Indicators that help measure social innovation initiatives can be identified as prerequisites, conditions of implementation and sustainability criteria, defining the structured conditions of the innovation process per phase. In addition, several levels of social innovation efforts are possible. Measuring macro-level social innovation, it is necessary to examine regional contexts, with the method of analysis of the connection network, and also with a systematic approach. Regional social innovation measurement can be used to analyze local and regional cooperation and initiatives. The study analyzes the conditions and measurement possibilities of micro-level social innovation, their generating potential and investigates the speed of organizational innovation. An example of good practice in the municipality is presented as a case study, defining the conditions that help to evaluate social innovation by determining a process-oriented framework.
The Development of the Egyptian Technical Secondary Education Considering Some Contemporary Global Trends: An Analytical Study

Published: February 2019

Technical education is the base for all development efforts in society. It plays an important role in pushing up the development wheel and in achieving its maximum rates. Whatever the development plans quality, they couldn't achieve their goals and targeted rates without the availability of scientifically and technically qualified human cadre in all work and production fields. Studies clarified that Egyptian technical secondary education suffers from many problems as the weak of its programs leading to negative effects on the proficiency of their students and their outcomes, their inconvenience to the labor market and making gap between the educational outcomes and technical education institutions and leading to the inferiority of the social status of this sort of education considering its relationship with hand work. Thus, reinforcement of the positive social sight towards vocational and technical education in Egypt represents a challenge. This study attempted through using the analytical method, through analyzing the educational literature to identify the contemporary global trends in developing technical education, how to apply every trend in the other world countries and to identify the positive and negative sides of applying every trend. Thus, the development of Egyptian technical secondary education could be identified and its requirements and means.
Investigating Greek EFL Coordinators’ Involvement in Online Elteachers Communities of Practice as a Means of Professional Development
Authors: Kourkouli Katerina
Published: February 2019

This paper examines Greek EFL Coordinators’ involvement in online ELTeachers Communities of Practice (CoPs) and its impact on their own and their trainees’/teachers’ professional development. The study focuses on four (4) Greek EFL School Advisors who acted as Coordinators of four online CoPs training fourty-nine (49) EFL teachers using an online platform named 2gather developed by the University of Athens in the context of a national in-service professional development project in Greece. Founded on the theory of situated learning, CoPs have been defined as “groups of people who share a concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis” (Wenger et al., 2002). The study involved monitoring the development of four online ELTeachers CoPs and their respective Coordinators’ patterns of involvement and response using a mixed-methods approach which combined quantitative data and qualitative research of collective case studies (Dornyei, 2007) of the four groups of teachers. A comparison of the Coordinators’ implementation of meaningful professional development (Franke et al., 2001) activities “before” and “after” their involvement in the online CoPs was carried out. Findings delineate the extent of the Coordinators’ “reformed” training practice in terms of professional development activities provided to the teachers “before” and “after” their CoP involvement as well as their report on their teachers’ and their own perceived benefit. Results also highlight the role of the Coordinators’ attitude towards the innovative model of teacher education for its feasibility and viability in Greece and contribute to furthering our understanding of effective implementation of online CoPs in the context of continuing professional development.
Similarities in the Syntactic Structure of the German and Croatian Language
Authors: Svoboda Manuela
Published: February 2019

The purpose of this paper is to analyse any potential similarities between the Croatian and German language and present them adopting a contrastive approach with the intent of simplifying the learning process in regards to the German syntactic structure for Croatian German as foreign language students. While consulting articles and books on the theories and methods of foreign language teaching, attention is usually drawn to differences between the mother tongue and the foreign language, especially concerning false friends etc. The same applies to textbooks, workbooks and how teachers behave in class. Thus, it is common practice to deal with the differences between the foreign language and the mother tongue but less with similarities. This is unfortunate considering that this would likely aid in acquiring certain grammatical and syntactic structures of the foreign language. In the author's opinion, similarities are as, if not more, important than differences. Therefore, in this article the existence of similarities between the Croatian and German language will be examined closer with a main focus on the segment of sentence types. Special attention is drawn to subordinate clauses as they play an important role when speaking and/or translating sentences from Croatian to German and vice versa. In order to present and further clarify this matter, subordinate clauses in both the German and Croatian language are defined, clarified and listed to gain an oversight and to present possible similarities between the two. In addition, the method to identify subordinate clauses in a sentence is explained as well as what they express, which conjunctions are being used for each type of subordinate clause in both languages and where the similarities and/or differences between the two languages lie.
Optimal Control and Real-Time Simulation of Hybrid Marine Power Plants

Published: February 2019

With significantly increasing concerns about greenhouse effects and sustainable economy, the marine industry presents great potential for reducing its environmental impact. Recent developments in power electronics and hybridisation technologies create new opportunities for innovative marine power plants which utilize both traditional diesel generators and energy storage like batteries and/or supercapacitors as the power sources. However, power management of such complex systems in order to achieve the best efficiency becomes one of the major challenges. Acknowledging this importance, this research aims to develop an optimal control strategy (OCS) for hybrid marine power plants. First, architecture of the researched marine power plant is briefly discussed and a simple plant model is presented. The generator can be used to charge the batteries when the ship works with low power demands. Conversely, this battery energy can be used as an additional power source to drive the propulsion or assist the generators when necessary. In addition, energy losses through braking can be recuperated and stored in the battery for later use. Second, the OCS is developed based on equivalent fuel consumption minimisation (EFCM) approach to manage efficiently the power flow between the power sources. This helps the generators to work at the optimal operating conditions, conserving fuel and lowering emissions. In principle, the EFCM is based on the simple concept that discharging the battery at present is equivalent to a fuel burn in the future and vice-versa and, is suitable for real-time implementation. However, instantaneously regulating the power sources’ demands could affect the system stability as well as the lifetime of the components.  To overcome this drawback and to achieve smooth energy management, the OCS is designed with a number of penalty factors by considering carefully the system states, such as generators’ fuel consumption and dynamics (stop/start and cranking behaviour), battery state of charge and power demands. Moreover, adaptive energy conversion factors are designed using artificial intelligence and integrated in the OCS design to improve the management performance. The system therefore is capable of operating in the highest fuel economy zone and without sacrificing the overall performance. Furthermore, a real-time simulation platform has been developed for the future investigation of the control logic. The effectiveness of the proposed OCS is then verified through numerical simulations with a number of test cases.
