World Ocean Circulation Experiment – Argo Global Hydrographic Climatology
Authors: Gouretski Viktor
Published: September 2018

Abstract. The paper describes the new gridded World Ocean Circulation Experiment-Argo Global
Hydrographic Climatology (WAGHC). The climatology has a 1∕4∘ spatial resolution resolving the annual cycle of temperature and salinity on
a monthly basis. Two versions of the climatology were produced and differ
with respect to whether the spatial interpolation was performed on isobaric or isopycnal
surfaces, respectively. The WAGHC climatology is based on the quality controlled
temperature and salinity profiles obtained before January 2016, and the
average climatological year is in the range from 2008 to 2012. To avoid biases due to the significant step-like decrease of the data below
2 km, the profile extrapolation procedure is implemented. We compare the
WAGHC climatology to the 1∕4∘ resolution isobarically averaged WOA13
climatology, produced by the NOAA Ocean Climate Laboratory (Locarnini et
al., 2013) and diagnose a generally good agreement between these two gridded
products. The differences between the two climatologies are basically attributed
to the interpolation method and the considerably extended data
basis. Specifically, the WAGHC climatology improved the representation of
the thermohaline structure, in both the data poor polar regions and
several data abundant regions like the Baltic Sea, the Caspian sea, the Gulf of
California, the Caribbean Sea, and the Weddell Sea. Further, the dependence of
the ocean heat content anomaly (OHCA) time series on the baseline
climatology was tested. Since the 1950s, both of the baseline climatologies
produce almost identical OHCA time series. The gridded dataset can be found
at https://doi.org/10.1594/WDCC/WAGHC_V1.0 (Gouretski, 2018).

Abstract. The maximum possible earthquake magnitude is one of the fundamental parameters to assess possible threats and effects on populations and infrastructures. Empirical scaling laws between fault/slip dimensions and earthquake magnitude can be used to assess this fundamental parameter. Upon the assumption of the reactivability of any fault, these seismic scaling laws are used at the national scale in Italy, considering all known faults regardless of their age, stress field orientation, or strain rate. Italy is a suitable case for comparing the fault-size-derived seismic magnitudes with the existing accurate catalogues of historical-instrumental earthquakes. To do so, (1) a comprehensive catalogue of all known faults is compiled by merging the most complete databases available, (2) the potential expected maximum magnitude of earthquakes (PEMM) is simply derived from fault dimensions, and (3) the resulting PEMMs are compared (i.e., the mathematical difference) with catalogued earthquake magnitudes. Results show that the largest PEMMs as well as the largest differences between PEMMs and catalogued magnitudes are observed for poorly constrained faults (inferred from subsurface data). Where, in contrast, the knowledge of faults is geologically well constrained, the calculated PEMM is often consistent with the catalogued seismicity, with the 2σ value of the distribution of differences being 1.47 and reducing to 0.53 when considering only the M ≥ 6.5 earthquakes. This overall consistency gives credibility to the used empirical scaling laws; however, some large differences between the two datasets suggest the validation of this experiment elsewhere. The largest differences are probably connected with the partial activation of presumed long continuous faults. The main advantages of this method are its rapidity, once the faults are mapped, and its independence from temporal and (paleo)seismological information. The novelty is not the method, but its use at the national scale also for faults considered inactive. This method cannot, however, be a substitute for time-dependent (paleo)seismological methods for seismic hazard assessments. Rather, it can rapidly provide a perspective time-independent seismic potential of faults.

People Connecting People: Cultural Diplomacy and the Work of the American Research Center in Egypt
Authors: Scott Gerry D.
Published: September 2018

The American Research Center in Egypt (ARCE) was founded in 1948 to assist Americans in obtaining their permission to conduct research in Egypt. By the 1960s ARCE expanded its mission to include a fellowship program, and in the 1990s, ARCE again expanded its mission to include an ambitious program of monument conservation and personnel training. Since 1995 ARCE's efforts, in collaboration with the United States Agency for International Development USAID and Egypt's Ministry of Antiquities, have resulted in more than 70 successful projects. This article discusses how these programs—sponsored archaeology, fellowships, conservation and personnel training, and community outreach—connect people to promote scholarship, preserve cultural heritage, and present a positive cultural presence for the United States in Egypt.

Published: September 2018

In my year as a Council of American Overseas Research Centers (CAORC) Mellon Mediterranean Regional Research Fellow, I visited four countries—Egypt, Lebanon, Saudi Arabia, and Sudan—for my dissertation research on ancient Egyptian living-rock stelae. Each of these countries afforded me unique and sometimes sobering experiences as a scholar, a field researcher, and an American abroad. In this personal reflection on my fellowship term, I recount some of the encounters that left lasting impressions on me. These experiences would not have been possible without the support of CAORC.
¿Arqueología salvadoreña? : una utopía en construcción
Authors: Escamilla Marlon
Published: September 2018

Al hablar de arqueología en El Salvador, es necesario generar una discusión en torno a diferentes aspectos socioculturales y políticos que han influenciado la práctica de la disciplina arqueológica en el país. Desde sus inicios, la arqueología en El Salvador ha sido influenciada principalmente por los planteamientos metodológicos y teóricos de la arqueología norteamericana. A mediados de la década de los noventa se funda la carrera de Arqueología en El Salvador, permitiendo formar arqueólogos nacionales. Sin embargo, a pesar de las dos décadas transcurridas y de los más de treinta arqueólogos graduados con que cuenta el país, todavía no se puede hablar de una arqueología salvadoreña ¿Por qué? ¿Cuáles son las razones que impiden que la arqueología salvadoreña crezca y se desarrolle como tal? El presente artículo analiza y discute algunos aspectos que están afectando y atrasando el crecimiento y la madurez de la arqueología como disciplina.Entorno, abril 2015, número 58: 61-67
Gender Equality in Turkish Higher Education
Authors: Cobanoglu Fatma
Published: September 2018

The moulds of masculinity and femininity determined by society are not only determinants of the way in which individuals behave in society, but also determinants of the production and distribution of the resources. The steady development of societies can be achieved when men and women have the equal power with equal opportunities and resources to shape their own lives and to contribute to their families, societies and countries. The internationally recognized indicators of aforesaid gender mainstreaming are the areas of Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment. In Turkey, even though the legal basis of equality of women and men in these areas have been strengthened through legislative regulations enforced, the need to overcome the obstacles women face when participating to social life as complete and equal individuals and taking all precautions for this is still ongoing. In this study, gender equality in the Turkish higher education system was examined. For this purpose, the schooling rates in higher education, employment rates and participation rates in decision making mechanisms in management of women were examined in the light of gender equality indicators. In this study, which was conducted by document reviewing among qualitative research methods, official websites and documents of international organizations and Turkish official institutions were examined in order to access reliable documents related to Turkish Higher Education and gender equality variables. The survey concluded that while the schooling rates in the Turkish higher education and employment rates of women are high, the proportion of female academicians decreased as the academic degrees increased and that the horizontal disintegration patterns between the scientific areas are more visible on the basis of sub-branches. Furthermore, it has been found out that women are not adequately represented in decision-making mechanisms, even though they provide the necessary conditions.

Authors: Khusiafan Firas J.
Published: September 2018

Aircraft industry is also finding its way to adapt on the increasing demand not only considering aircraft safety and customer requirements, but also on the increasing legislative requirements in terms of resource efficiency and gas emissions. This document explores Kevlar 49’s application on aircraft components and why this material is specifically selected for such applications above any other Kevlar type of materials. Its functions, properties, advantages and disadvantages are discussed together with some alternative materials in lieu of Kevlar 49. In order to provide credible information, literature search was conducted using significant keywords in Google Scholar and journal repository Deepdyve. Kevalr ® 49 is considered an exceptional material for reinforcement to produce aircraft components. It has high tensile strength, lightweight, inert on some conditions, stiff, and resilient. However, Kevlar’s has poor compressive strength, workability and is overly stiff for some applications. Another disadvantage is its cost, though it was shown to belong to a middle ranged material relative to carbon fiber and Boron. But overall, there are extensive applications in aircraft components that are now continuously using this material as reinforcement with other materials like carbon and boron to arrive on an ideal blend of product.

Published: September 2018

The purpose of the study was to investigate the views of preservice teachers about use of slowmation in biology teaching. In the study, descriptive model was used. The participants were 12 third-grade preservice teachers in the department of Biology Education at Ziya Gökalp Education Faculty of Dicle University in the Spring Term of the academic year of 2016-2017. The research data were collected via observations and semi-structured interviews. In the research process slowmation activities were carried out with preservice biology teachers and at the end of these activities the preservice teachers’ views about the activities were determined. The data collected in the study were analyzed using the content analysis method. As revealed by the analysis of the data, the preservice teachers thought that the slowmation activities contributed to the development of some 21st century skills such as creativity, communication and cooperation skills, information literacy, research skills, technology and media literacy skills. In addition, the preservice teachers reported that the process of creating slowmation was interesting and that they entertained in the process. On the other hand, the preservice teachers also stated that it was difficult to create scenarios and that they experienced problems with the materials used. Moreover, it was seen that the preservice teachers faced problems with the video editing software and that they experienced disputes regarding the distribution of duties during group works. The preservice teachers also put forward suggestions regarding the use of slowmation activities in biology teaching saying that teachers and students could work together in the application process; that activities could be carried out to summarize the subject and to increase permanency; and that different tools and software programs could be used.

Published: September 2018

The methanolic extract obtained from leaves, steam and seeds of M. officinalis growing in Karak city-Jordan, was investigated, discussed for its phytoconstituents for the first time and analyzed by GC-MS instrument with BSTFA and Heptan solvents. Plant parts were collected during the spring semester 2018. Results showed that leaves extract have twenty one major and minor natural compounds available in all parts. Six of them which were above 1 % have been found in the extract of leaves more than other parts of the plant. Leaves extract are a good source of various phytoconstituents. These natural compounds gave leaves an important role to use it as anticancer and sedative due to the presence of Palmitic acid and polar compounds. Leaves are much interesting part due to the availability of these bioactive compounds as major and minor compounds more than other parts. Thus, the isolation of leaves phytochemical compounds will give fruitful results for further detailed study. 
Prevalence of Prefabricated Structures in Academic Discourse: A Corpus-Based Study
Authors: Yousaf Muhammad , Shehzad Wasima
Published: September 2018

Multiword structures that appear in a text more than expected frequency are called lexical bundles. These prefabricated structures vary in length but the most common lexical bundles are four-word lexical bundles which have been explored by many scholars worldwide. The current study aimed to explore five-word lexical bundles, which have lesser been researched. For this purpose a corpus of about 4.7 million words was compiled which consists of PhD dissertations written in Pakistani context. Moreover, the dissertations were selected from three different disciplines to make the study cross disciplinary. The corpus was analyzed according to the taxonomy of lexical bundles given by Biber et al. (1999). The analysis shows that lexical bundles are predominant feature of PhD dissertations in Pakistani context. Moreover, frequency of lexical bundles varies from discipline to discipline, and the structural variation of lexical bundles is also found across disciplines. Dominant structures across disciplines are not fixed as Prepositional Phrase Fragments is the dominant category in the corpus of English Studies and corpus of Social Sciences, whereas, Verb Phrase Fragments is the dominant category in the corpus of Bio Sciences.
Students’ School Engagement and Their Truant Behavior: Do Relationships with Classmates and Teachers Matter?
Authors: Teuscher Selina , Makarova Elena
Published: September 2018

Research on school dropout suggests that the decision to drop out of school is not a sudden or immediate one, but rather the result of a long-term process of withdrawal from school. While school engagement and truancy are among the most prominent constructs to be associated as precursors of school dropout, the relationship between these two constructs needs further analysis. Our study establishes more comprehensive understanding of school engagement and truancy by focusing on students’ individual characteristics and their relationships in school, particularly the student-teacher relationship and relationships with peers. It demonstrates that among the individual characteristics the migration background is crucial for school engagement, while the student age is important for truancy. Furthermore, peer-relationships are positively related to students’ school engagement, but not to their truancy. Furthermore, a good student-teacher relationship not only has positive impacts on students’ school engagement, but is also negatively associated with truancy, while school engagement mediates this path.

Published: September 2018

This study aimed at finding out factors affecting pupils’ absenteeism at Felicomfort JHS at Amamoma within the University of Cape Coast, Ghana. The total population was 145 covering the JHS1, JHS2, JHS3 pupils and teachers of the school. Purposive sampling technique was used to select 34 respondents. These were made up of 10 out of 15 teachers, 10 parents out of 53 and 14 pupils out of their accessible population of 56. Pretest, posttest, questionnaires and interviews were used to collect data from respondents. Case study design was used for the study and data analysis was done, using mean values, frequency and percentage counts with the Predictive Analytical Software (PASW) version 21. Key findings of the study indicated that 71.4 percent of absenteeism was due to teachers’ inability to care and find out from pupils the cause of their absenteeism, while 70 percent of respondents indicated that parental lack of care was the major cause of their absenteeism. However, majority (10) of respondents (71%) disagreed that pupils’ attitudes were part of the contributory factors to their habitual absenteeism. The overall percentage mean (58%) representing 8 of the pupils discounted teacher factor as responsible for their absenteeism. It was recommended that government through the District Assemblies offer some financial assistance to poor and single parents to enable them to adequately cater for their wards at school.
Accuracy, Conservatism and Parsimony of Three Vapour Intrusion Models Used in Sweden
Authors: Provoost Jeroen , Nouwen Stephanie , Bronders Jan
Published: September 2018

This study presents an evaluation of three screening-level models, namely the Dilution Factor (DF) model from 1996, the update version from 2005, as well as the Johnson and Ettinger model (JEM) from 1997, that are applied within the frameworks for contaminated land management (CLM) in Sweden. This evaluation applies, besides a deterministic approach (point estimate), a probabilistic assessment plus sensitivity analysis. The latter approach allows the models to be ranked according to conservatism, accuracy and parsimony by contrasting predicted and observed soil and indoor air concentrations for two contaminants (benzene and ethylbenzene), as to determine their suitability for application within CLM. The results and conclusions from this study suggest that the most accurately model for predicting the soil and indoor concentration is the JEM followed by the DF 2005 and 1996. Predictions of the soil air concentration are primarily driven by variation in physico-chemical parameters. The variation in indoor air concentration by physico-chemical and/or soil parameters for the DF models, while for the JEM soil parameters dominate. The deterministic analysis showed that default parameter values could be revised as to increase the conservatism, and be closer to the probabilistic 95-percentile predicted indoor air concentration. The DF 1996 model includes a limited number of parameters, and this analysis shows that a model with more parameters is more accurate, and less conservative. The DF 2005 seems to be the most parsimonious model as it is accurate, sufficiently conservative, and has 14 parameters, whereas the DF 1996 with 9 parameters is the most conservative and the JEM with 27 parameters the most accurate with an increased probability to produce false negative predictions. For the latter some of the dominant parameters cannot easily be measured on site.
Automatic Recovery of Database Structure (ARDS)

Published: September 2018

One of the evolutions of information technology which is a very fascinating feature is the application of the auto recovery. This feature enables an external system to automatically diagnose other systems, detects the error that causes the failure, then recovers and reconfigures the system. The concept of software and web auto recovery is widely used in much software such as windows operating system which restores and recovers tools.  Since the aim is to fast recover the application and keep it running and available as optimal as possible then it will be suitable to apply this capability to the database applications to fast recover from any unexpected change that may happen. This paper proposes an auto-recovery system that monitors, diagnoses, checks and heals database applications automatically and immediately with unnoticeable recovery time. The aim is to recover and to redo the changes that happened to the database by internal unauthorized user or external intrusion. To test the practical applicability of the proposed methodology, an application has been developed to demonstrate the methodology and apply it for real time database applications. The results of experiments performed on different scenarios demonstrated the ability of the proposed framework to recover database applications.

Een onbevredigende studie van het Nederlandse emancipatiebeleid
Authors: Outshoorn Joyce
Published: September 2018

An unsatisfactory study of Dutch gender equality policy.

This book focuses on gender equality policy in the Netherlands since 1974, when the issue made it to the political agenda and the major policy goals became attaining equal rights for women and equal status between women and men. The authors offer a chronological overview, intended for a wider audience, and focus mainly on the ‘second wave’ of feminism and the national level. In providing an overview, the book could have been a welcome addition to the existing literature on the topic, but it is marked by several flaws. It makes little use of this existing literature on the topic, neglects the policy input of women’s movement organizations, and the legal struggle on equal treatment. As the book lacks a central question, it does not provide an analytical analysis, an adequate definition of the scope of gender equality or discussion of the political difficulties of intersectoral policies. It also does not deal with the issue of implementation. Finally, there are too many inaccuracies and flaws in the references to make the book a reliable guide for a wider audience into the area.

Eenzijdig gerichte rechtshandeling of overeenkomst? Dat verdient uitleg!

Op 24 februari 2017 heeft de Hoge Raad een arrest gewezen over de uitleg van een eenzijdige rechtshandeling, neergelegd in een brief tussen zakelijke partijen (het ‘Parkking-arrest’). Deze bijdrage behandelt de vraag of de Hoge Raad met het Parkking-arrest een ‘nieuwe uitlegmaatstaf’ heeft ontwikkeld voor de uitleg van eenzijdige rechtshandelingen.

In het vervolg van deze bijdrage wordt toegelicht hoe de kwalificatie van een eenzijdig opgesteld document (als eenzijdige rechtshandeling of als onderdeel van een meerzijdige rechtshandeling) een uitlegdiscussie zou kunnen beïnvloeden. Een juiste kwalificatie is van belang voor het vertrekpunt van de uitleg, de relevante gezichtspunten bij de uitleg, toepasselijke rechtsregels, rechtsgevolgen en het gewicht dat aan de ene of de andere omstandigheid wordt toegekend. Dat antwoord kan dan weer van belangrijke invloed zijn op een (voorlopig) bewijsoordeel en – bij gevolg – tot een andere uitkomst leiden in een procedure.

Het nieuwe Belgisch Burgerlijk Wetboek; een slag bij Waterloo? Over het nieuwe contractenrecht van onze zuiderburen

Er komt een Nieuw Belgisch Burgerlijk Wetboek aan. Tot op heden hanteert België nog een minimaal aangepaste versie van de Code Civil Napoléon uit 1804. De bejaarde leeftijd van het wetboek laat zich echter op meerdere fronten gevoelen, waardoor de wetgever de tijd nu rijp acht om het Burgerlijk Wetboek te hervormen. Het Voorontwerp Boek 5 «Verbintenissen» komt in de hervorming van het Belgische burgerlijk recht een centrale plaats toe. Het zal mogelijk worden ingevoerd zonder dat wordt gewacht op de voltooiing van de andere onderdelen van het wetboek. Voor het contractenrecht betekent dit dat een nieuw evenwicht wordt gezocht tussen de autonomie van partijen en de mogelijkheden voor de rechter om op te treden in het algemeen belang of in het belang van de zwakkere partij. Deze bijdrage belicht de achtergrond van het Voorontwerp, alsook de redenen en doelstellingen van de hercodificatie. Daarbij wordt ook ingezoomd op de inhoud van het nieuwe Belgische contractenrecht en worden enkele belangrijke wijzigingen besproken.
Evaluation of species inter-relations and soil conditions in Arnica montana L. habitats: a step towards active protection of endangered and high-valued medicinal plant species in NE Poland

Published: September 2018

Arnica montana L. is a critically endangered and highly valued medicinal plant species in Europe. We show the inter-relationships between arnica and accompanying plant species, as well as soil factors, that promote the persistence of the studied forest arnica populations in terms of active protection of this species in the northeast region of Europe. The population characteristics and plant species composition were assessed during a field study. Additionally, soil samples were taken and analyzed to assess variation in soil conditions in the habitats of arnica populations. Correlations between population characteristics and soil properties were highlighted. The forest habitats of arnica presented in this study differ from those described in other European mountain and submountain areas. The sandy and very poor soils are characterized by a very low content of macro- and microelements, and a strong acid reaction. The positive correlation between population characteristics and Ca and K indicates an important role of these macroelements in flower head production. Acidity, K, Ca, the sum of exchangeable bases, and base saturation play crucial roles in the persistence of arnica populations in pine forests. The level of acidity and its consequences result from soil-forming processes and climatic conditions rather than air pollution. When planning active protection scenarios, special attention should be paid to the frequency and cover of Vaccinium myrtillus, which can act as a competitor in forest habitats. Assessment of soil conditions that favor the persistence of the studied arnica populations and species relationships is important for improving knowledge of the ecology of the species and for the active protection of endangered plant species.
Decisional processing on parking behavior in entropic settings
Authors: Ferrarese Moreno
Published: September 2018

This paper surveys the most recent advances in the context of decisional processing with focusing on the parking behavior in entropic settings, including the measures and the necessary mechanisms for the interaction of the actors-players, and their connection to decisional processing theory. The aim of this article is to provide a critical review of the most fashionable models and methods in parking lot financial design: the first class of methods covers the approach of analysis with the random entropic model; the second class of methods is the decisional processing through rational choice models as rational individual evaluations. Both techniques are described in detail in sections; we illustrate them using the well-known and easy multimodal problem approach and then we present the advanced applications. Thus, it is possible to identify all strong and weak points of the models and to compare them for a best feasible solution for parking lot economic and financial design. Taking into account a close equivalence between the aggregate methods of entropy maximization and disaggregated microeconomic method of discrete choice models, based on random utility theory, we try to provide a critical approach of it through the rational choice models and to underline the possible benefit of it for the problem decision.

Published: September 2018

The basis of each IT system is data exchange both between individual modules of program and between program and user. The number of exchanged data and the number of operations on the data, which should be performed, require application of professional tools allowing for collecting and performing operations on multiple types of data. One of these tools are databases, which are an essential part of any IT system. With database designing are connected many decision problems which can occur both during the construction of database management system and at the stage of integration of entire user application with developed database. The article presents typical decision problems connected with designing of databases. These problems mainly concern sphere of information technology (including the programming language or recovery mechanism of database after the failure). Database architecture for typical IT system from the point of view possible paths for users were discussed, and role of catalogues played in development of database were presented. In addition, modular structure of the database, which was developed for the system SIMMAG3D for modelling and visualization of warehouse facilities in 3D was shown. This system is being developed under a project financed by the National Centre for Research and Development. We discussed in detail one of the essential elements in developed database - catalogues of means of external and internal transport, non-mechanical equipment and accessories which are essential from the point of view of the work load.

Published: September 2018

The paper presents issues related to design and organization of the warehouse process. Draws attention to problems of modelling logistics facilities and processes occurring in them. Paper also points out the essence of correct operation of warehouses and associated with this risks for supply chain. Warehouse processes have been properly defined and divided into smaller components, like: phases of process, activities, sets of procedures, procedures or working movements. Paper presents various possible configurations of warehouse processes, which were named as warehouse strategies. Warehouse process strategy is a part of warehousing. It determines the sequence of warehouse operations. These operations are related to internal transport, cargo form transformation and cargo buffering. In paper it is noted that the warehouse strategy depends on the several technical and organizational factors and is associated with a certain probability. This probability can be estimated based on data analysis concerning logistics processes in the specified warehouse facility. As shown in case study, appropriate selection of warehouse strategies determines possibility of fulfilling customer order in time and costs that are acceptable for him.
Mechanical analysis and research of the conveyor belt of plane turning belt conveyor based on Discrete Element Method
Authors: Li De-yong , Wang Shuang , Hu Kun
Published: September 2018

In view of the size and the change of the load force of the conveyor belt at the turning point of the plane turning belt conveyor, the influencing factors of the stress of the conveyor belt at the turning point of the plane turning belt conveyor under full load condition are analyzed. A three dimensional model of the turning point of the plane turning belt conveyor is established. Combined with previous research experience, the formula for calculating the load is put forward. Based on discrete element method, multiple sets of internal curve elevation angle and the belt speed are used for dynamic simulation analysis. The results showed that the middle of conveyor belt is the most stressed, the lateral force second, the force of the inner conveyor belt is the least. Outside force increases with the increase of speed; there is no change in the middle band; the inner band force decreases with the increase of the velocity. Outside force decreases with the decrease of the inclination angle. With the change of the inclination angle, the force is basically unchanged. With the decreasing of the inclination angle, the force increases gradually. By optimizing the design parameters of the plane turning belt conveyor, the force of belt is reduced, and the service life of belt is improved.

Published: September 2018

The irregularities of evolutionary development, continuous improvement of environmental component into transport and raise many unsolved problem in the fields of transport in logistics systems and material flows management. The city parameters analyses had highlighted connections with transport services technology. Also the distribution stage of the logistic chain, which consists of following market participants: incoming material flow, retailers and Transportation Company (carrier) in different cities has been considered. Transportation service is made by road transport. The paper compares results of transportation servicing in different cities and logistic chains with same technology. As performance indicator net present value has been used. Existing criteria for evaluating the effectiveness of distribution of material flows does not sufficiently take into account the time value of money and possible options for investment, so when estimating the performance of servicing of business investment indicators should be used. Paper should elucidate the impact of cities on the transport service efficacy. Practical suggestions on logistics system functioning and transportation service of retailers in urban area have been proposed. Obtained results discovered overall impact of city’s parameters (density of streets and roads network’ irregularity factor; automobilizationlevel; urban square; scheme of road network; city radius) on logistics according to model which include more than 50 parameters and allows finding regularities of changing logistics efficiency on them.
SIMMAG3D as a tool for designing of storage facilities in 3D
Authors: Jacyna Marianna , Wasiak Mariusz , Bobiński Andrzej
Published: September 2018

Designing of storage facilities is an interdisciplinary process that requires consideration of technical, economic, social or environmental issues. Storage facilities, as a part of supply chain are designed to provide customers availability of goods at a certain time, quantity and place. This involves the functions resulting therefrom, such as storage, sorting, picking, packing, etc. The efficiency of processes in the supply chains is strongly influenced by the location and shape of the storage facilities that are critical components. These issues are multi-threaded, and they are subject of an iterative approach in which information tools are playing a special role. One of such tool is the SIMMAG3D system. It is a system for modelling and visualization in 3D of warehouse facilities, which was built based on developed mathematical models, computational algorithms and functional dependencies necessary for the designing of storage facilities.

Electrical power infrastructure for modern rolling stock with regard to the railway in Poland
Authors: Szeląg Adam
Published: September 2018

Implementing high-speed trains on Polish railway lines requires a new approach to the issue of power and energy supply via a 3 kV DC power system. Due to the control systems used, modern rolling stock equipped with asynchronous drive allows maintaining a set speed, as far as a locomotive’s power and voltage in a catenary allow it. Characteristics of traction vehicles with asynchronous drives enables run at voltage lower than the rated voltage, however, it entails decrease of consumed power (required for locomotives with power above 2 MW) and loss of motion dynamics. Modernisation of a railway power supply system conducted in Poland since the mid-1990s of the 20th century has intensified in the past couple of years (so-called MUZ-I program) due to the purchase of Pendolino trains, and it primarily include the main lines. A number of modernisation investments (lines E65, E20, E30) are implemented with co-financing from the EU funds. Due to the predicted trains’ speed (200 km/h and above), in order to fulfil the requirements specified in TSI, a power supply system on these lines should ensure achieving high parameters, that is supply of trains with current up to 3.2 kA, while the so-called mean useful voltage should not be lower than 2.8 kV. The article presents solutions introduced on Polish railway and aiming at adjusting the power supply used to the TSI requirements. The range of conducted modernisation works allows for conclusion that the process is in fact a re-electrification of railway power supply systems.

Width design of the urban rail transit stations circulation facilities is a vital issue. The existing width design approach failed in fully considering the essential factors such as fluctuation in passengers’ arrival process, fluctuation and state-dependence in passengers walking speed and the blocking when passengers’ demand exceeds the capacity of facilities. For this purpose, a PH-based simulation-optimization approach is proposed that fully considers the fluctuation, the state-dependence, Level of Service (LOS) and blocking effect. This novel approach provides automatic reconfiguration of the widths of circulation facilities by a concurrent implementation of a PH-based Discrete-Event Simulation (DES) model and the Genetic Algorithm (GA). The proposed PH-based simulation- optimization approach and the existing design approaches based on the exponential and deterministic models are applied to design the widths of circulation facilities. The results reveal that the circulation facilities designed by the proposed approach have larger widths. Similarly, increase in the SCV of arrival interval results in increasing the widths designed by the proposed approach increase while the widths of the other two approaches stay the same. The width designed of the proposed approach increase at faster rate than that of the other two approach when the passengers’ arrival rate increases.

As the very important parts of the expressway system, on and off ramps have a great effect on the operation effect of expressways. Once congestion occurs at on and off ramps, it will directly affect the safety of the expressway and vehicles. So this paper first analyzes the location design of on ramps, the length and the influences on the expressway running state of off ramp downstream traffic state, and establishes the expressway operation models based at on and off ramps. The expressway operation models include off ramp delay model, on ramp delay model, expressway delay model and side road delay model under the influence of the distance between on and off ramp and traffic volume. At the same time, the paper analyzes the connection between the traffic operation state and traffic safety, and establishes the expressway safety model based on congestion degree. Through simulation verification, the impact of on and off ramp on the security of the expressway is analyzed. In the simulation, safety rank division is simulated to verify and safety index of different safety ranks. Finally the paper concludes that the delay caused by traffic of the on and off ramps can decrease the safety of expressway.
Forecasting travel time reliability in urban road transpo

Assessment of travel time reliability as a fundamental factor in travel behaviour has become a very important aspect in both transport modelling and economic appraisal. Improved reliability could provide a significant economic benefit if it is adequately calculated in cost-benefit analyses for which the theoretical background has already been set. However, methods to forecast travel time reliability as well as travel behaviour models including its effects are rather scarce and there is a need for development in this field. Another important aspect could be the influencing factor of reliability in travel demand management and related policy-making. Therefore, this paper intends to further analyse reliability focusing exclusively on urban road transport based on automatic measurements of journey times and traffic volumes from a dataset of the city of Budapest. The main finding and the novelty of the study is a model which can forecast the standard deviation of travel times based on the volume-capacity ratio and the free-flow travel time. The paper also provides a real-life numerical experiment in which the proposed model has been compared with other, existing ones. It proves that besides existing mean-delay-based models, travel time reliability can be forecasted based on the volume-capacity ratio with an adequate accuracy.
Government financial accountability: key problems and main trends in post-communist countries

Published: September 2018

The article deals with the problems of government financial accountability in post-communist countries. The purpose of the article is to justify the necessity of government financial accountability development, especially in post-communist countries. Several research methods were used. First of all, the positive economic approach was used to describe the main ideas of government financial accounting and account- ability. Secondly, Worldwide Governance Indicators were used to prove the necessity of government financial accountability development in post-communist countries. Thirdly, by using an institutional analysis, the main problems in government financial accountability were discovered. Fourthly, ideas to improve government financial accountability were suggested. Those suggestions were developed, taking into account the specific problems of post-communist countries. Government financial accounting in post-communist countries, such as Ukraine, Belarus, and Russia, significantly lags behind the demands of modern society, affecting all members and levels of the national economy. Overcoming this problem is common to almost all post-communist countries. Effective finan- cial and economic information must meet basic quality characteristics – relevant, significant, objective, comprehensive, neutral, and without error. Post-communist countries which are not EU members must consider the important role of open financial information in the successful development of state and business spheres, increasing competitive advantage and attracting investors.
Management accounting practices in developing countries since the 1990s: the case of Poland
Authors: Szychta Anna
Published: September 2018

The aim of this paper is to identify the type of management accounting (MA) practices used in business entities surveyed in Poland, and to recognize the direction and factors of changes in MA methods and tasks in the al- most three decades of the dynamically developing market economy in Poland, after the change of the sociopolitical system at the turn of the 1980s and 1990s. The author answers several research questions based on a review of the previous literature and data obtained from three surveys conducted in 1999, 2005, and 2016. This study confirmed that the number of companies in Poland which have departments that carry out tasks in the area of MA/controlling has increased steadily. The research indicates that operational MA methods dominat- ed in enterprises between 2010–2015, just like in 2000–2005 and in the 1990s. It also found that in no more than 10% of the medium and large business entities which responded in 2016 are the methods of strategic MA used. In the first period of the development of the market economy in Poland, i.e., until 2004, many different economic and institutional factors influenced the introduction and change in MA practices, and in the next period, the respondents of the empirical studies pointed to economic factors as being more important. The paper contributes to the litera- ture on the development of MA in Central and Eastern European countries on the example of Poland.
