Cultural responsiveness in EFL teaching: reflections from native instructors
Authors: Cinarbas H. Ibrahim , Hos Rabia 
Published: July 2016

Abstract
In recent years, many international students from different parts of the world have been studying at Turkish universities, which creates a multicultural educational setting. Due to the multicultural educational setting, English has become the most widely used language for exchanging and sharing knowledge, therefore many international universities in Turkey put a great emphasis on English language education and offer English preparatory courses to students. In order to succeed at better language education, universities employ native English instructors to provide a richer language experience with cultural components embedded in language content. In this qualitative case study, cultural reflections of native English instructors at a Turkish university were investigated. Individual and focus group interviews were data sources for the study. Findings indicated that cultural responsiveness was considered to be constructed through time, and a necessity of orientation process was emphasized. However, the native instructors’ presumptions cause intolerance and underestimation of the host culture. In addition, educational issues and students’ misbehaviors, such as cheating and calling their instructors by their first name, were attributed to cultural background of the students.
A cross-cultural study of the smile in the Russian- and English-speaking world
Authors: Arapova Maria A. 
Published: July 2016

Abstract
Although the smile is a universal facial expression, the use of smiles in communication varies across cultures. This may lead to misunderstandings and miscommunication. Both Americans and Europeans experience the same frustration and communication failure when they do not find smiling faces in Russia. At the same time, it is common for Russian people to perceive the smiles of Westerners as artificial and insincere. What is the reason for such a difference in perception? Why don’t Russians smile in some situations?
The study of the use of the smile as a non-verbal sign in a few chosen communicative contexts across Russian, European and American cultures showed the difference in its meaning and distribution according to the cultural tradition. The reason could stem from the difference of Russia’s history when compared to that of Western Europe, as well as in the specific restrictions in Russian Orthodox Christianity and the traditions of laughter in Russia. All the meanings and specific cases of distribution are clearly retained and expressed in the languages. If we compare the Russian улыбка and улыбаться with the English smile, we can see both common and distinctive semantic elements and different connotations.
Nest site characteristics of the Great-spotted Woodpecker in a bottomland riparian forest in the presence of invasive tree species
Authors: Ónodi Gábor , Winkler Dániel 
Published: July 2016

Abstract
This study was carried out in Hungary, in an old unmanaged riparian poplar-willow forest during the breeding seasons of 2014 and 2015. The occurrence of two invasive tree species, the green ash and boxelder, is significant in the study area, which influences negatively the populations of native riparian tree species in Central Europe. We studied Great-spotted Woodpecker nest sites in the presence of these invasive species. Throughout the study period, eight and twelve nesting cavity trees were mapped. Trees were recorded in 20-20 circular plots of 0.05 ha both for each mapped nest trees and random plots as well. Species, diameter at breast height and condition were recorded for each tree. Composition and diversity of nest site and random plots were compared. Distributions and preferences were calculated for nest tree use. Most of the recorded trees were invasive. Nest site plots had more native trees compared to random plots. Nest site showed higher diversity in terms of all three variables. Decayed and dead willow and white poplar hybrid trees were preferred for nesting. Diameter at breast height of nest trees was between 30-90 cm. Studies about cavity excavators in transformed habitats have high importance for nature conservation of riparian forests.
Salmon: Robust Proxy Distribution for Censorship Circumvention
Authors: Douglas Frederick , Rorshach  , Pan Weiyang , Caesar Matthew 
Published: July 2016

Abstract
Many governments block their citizens’ access to much of the Internet. Simple workarounds are unreliable; censors quickly discover and patch them. Previously proposed robust approaches either have non-trivial obstacles to deployment, or rely on low-performance covert channels that cannot support typical Internet usage such as streaming video. We present Salmon, an incrementally deployable system designed to resist a censor with the resources of the “Great Firewall” of China. Salmon relies on a network of volunteers in uncensored countries to run proxy servers. Although any member of the public can become a user, Salmon protects the bulk of its servers from being discovered and blocked by the censor via an algorithm for quickly identifying malicious users. The algorithm entails identifying some users as especially trustworthy or suspicious, based on their actions. We impede Sybil attacks by requiring either an unobtrusive check of a social network account, or a referral from a trustworthy user.
Privately Evaluating Decision Trees and Random Forests
Authors: Wu David J. , Feng Tony , Naehrig Michael , Lauter Kristin 
Published: July 2016

Abstract
Decision trees and random forests are common classifiers with widespread use. In this paper, we develop two protocols for privately evaluating decision trees and random forests. We operate in the standard two-party setting where the server holds a model (either a tree or a forest), and the client holds an input (a feature vector). At the conclusion of the protocol, the client learns only the model’s output on its input and a few generic parameters concerning the model; the server learns nothing. The first protocol we develop provides security against semi-honest adversaries. We then give an extension of the semi-honest protocol that is robust against malicious adversaries. We implement both protocols and show that both variants are able to process trees with several hundred decision nodes in just a few seconds and a modest amount of bandwidth. Compared to previous semi-honest protocols for private decision tree evaluation, we demonstrate a tenfold improvement in computation and bandwidth.
DeNASA: Destination-Naive AS-Awareness in Anonymous Communications
Authors: Barton Armon , Wright Matthew 
Published: July 2016

Abstract
Prior approaches to AS-aware path selection in Tor do not consider node bandwidth or the other characteristics that Tor uses to ensure load balancing and quality of service. Further, since the AS path from the client’s exit to her destination can only be inferred once the destination is known, the prior approaches may have problems constructing circuits in advance, which is important for Tor performance. In this paper, we propose and evaluate DeNASA, a new approach to AS-aware path selection that is destination-naive, in that it does not need to know the client’s destination to pick paths, and that takes advantage of Tor’s circuit selection algorithm. To this end, we first identify the most probable ASes to be traversed by Tor streams. We call this set of ASes the Suspect AS list and find that it consists of eight highest ranking Tier 1 ASes. Then, we test the accuracy of Qiu and Gao AS-level path inference on identifying the presence of these ASes in the path, and we show that inference accuracy is 90%. We develop an AS-aware algorithm called DeNASA that uses Qiu and Gao inference to avoid Suspect ASes. DeNASA reduces Tor stream vulnerability by 74%. We also show that DeNASA has performance similar to Tor. Due to the destination-naive property, time to first byte (TTFB) is close to Tor’s, and due to leveraging Tor’s bandwidth-weighted relay selection, time to last byte (TTLB) is also similar to Tor’s.
Near-Optimal Fingerprinting with Constraints
Authors: Gulyás Gábor György , Acs Gergely , Castelluccia Claude 
Published: July 2016

Abstract
Several recent studies have demonstrated that people show large behavioural uniqueness. This has serious privacy implications as most individuals become increasingly re-identifiable in large datasets or can be tracked, while they are browsing the web, using only a couple of their attributes, called as their fingerprints. Often, the success of these attacks depends on explicit constraints on the number of attributes learnable about individuals, i.e., the size of their fingerprints. These constraints can be budget as well as technical constraints imposed by the data holder. For instance, Apple restricts the number of applications that can be called by another application on iOS in order to mitigate the potential privacy threats of leaking the list of installed applications on a device. In this work, we address the problem of identifying the attributes (e.g., smartphone applications) that can serve as a fingerprint of users given constraints on the size of the fingerprint. We give the best fingerprinting algorithms in general, and evaluate their effectiveness on several real-world datasets. Our results show that current privacy guards limiting the number of attributes that can be queried about individuals is insufficient to mitigate their potential privacy risks in many practical cases.

Authors: Polenakovic Momir , Gucev Zoran , Tasic Velibor 
Published: July 2016

Abstract
Pediatric kidney diseases were in the focus of the World Kidney Day 2016. Macedonian pediatric nephrologists gave their contribution with public appearance in kindergartens, primary and secondary schools, with interactive lectures and discussion with the youngest about the kidney function, healthy life style and simple measures to prevent kidney and urinary tract diseases. Besides promotive appearance in the media, series of lectures were presented in front of the health professionals. The aim was to attract the attention of the professionals for early diagnosis and prevention of kidney disease. The action starts in utero, followed by early postnatal imaging and assessment, conservative treatment and in selected cases surgical treatment. The emphasis is on the multidisciplinary and comprehensive approach to children and adolescents with kidney diseases.
The use of video in educational research and teacher training in the digital classroom
Authors: Falcinelli Floriana , Gaggioli Cristina 
Published: July 2016

Abstract
The introduction of new technologies, video in particular, in educational and pedagogical research has not only changed how research is conducted in the educational field but has also brought about significant changes in teacher training. The advent of digitalisation, along with the miniaturisation of both video cameras and storage media, has led to a dramatic increase in the use of video, particularly in terms of video production. This has led to the introduction of new teaching practices and new training initiatives derived from the analysis of these practices. The use of video, at an educational and didactic level on the one hand, and as an instrument for field observation on the other, offers a variety of benefits, along with some critical issues. One of the advantages is the capacity to allow for an analytical vision of complex actions, which may be reviewed at different times, by a variety of interlocutors. The aim of this study is to present a reflection based on research conducted in nine digital classes, focussing on the use of video as both an instrument for recording, collecting and analysing data, as well as a training tool in the didactic practice of teachers.
Exposures associated with clandestine methamphetamine drug laboratories in Australia
Authors: Wright Jackie , Edwards John , Walker Stewart 
Published: July 2016

AbstractThe clandestine manufacture of methamphetamine in residential homes may represent significant hazards and exposures not only to those involved in the manufacture of the drugs but also to others living in the home (including children), neighbours and first responders to the premises. These hazards are associated with the nature and improper storage and use of precursor chemicals, intermediate chemicals and wastes, gases and methamphetamine residues generated during manufacture and the drugs themselves. Many of these compounds are persistent and result in exposures inside a home not only during manufacture but after the laboratory has been seized or removed. Hence new occupants of buildings formerly used to manufacture methamphetamine may be unknowingly exposed to these hazards. Children are most susceptible to these hazards and evidence is available in the literature to indicate that these exposures may result in immediate and long-term adverse health effects. The assessment of exposure within the home can be undertaken by measuring contaminant levels or collecting appropriate biological data from individuals exposed. To gain a better understanding of the available data and key issues associated with these approaches to the characterisation of exposure, a review of the published literature has been undertaken.
Assessment of continental hydrosphere loading using GNSS measurements
Authors: Zygmunt Michał , Rajner Marcin , Liwosz Tomasz 
Published: July 2016

Abstract
Presented paper is dedicated to problems of deformation of the Earth's crust as a response to the surface loading caused by continental waters. The aim of this study was to specify areas particularly vulnerable to studied deformation and to compare calculated and observed displacements. Information of the continental water volume was taken from the WaterGAP Global Hydrological Model. Calculated values of the deformations were verified with the results obtained with programs SPOTL and grat. Vertical deformations were almost 10 times higher than the deformation in the horizontal plane, for which reason later part of the paper focuses on the former. In order to check agreement of the calculated and observed deformation 23 stations of International GNSS Service (IGS) were selected and divided into three groups (inland, near the shoreline and islands). Before comparison outliers and discontinuities were removed from GNSS observations. Modelled and observed signals were centred. The analysed time series of the vertical displacements showed that only for the inland stations it is possible to effectively remove displacements caused by mass transfer in the hydrosphere. For stations located in the coastal regions or islands, it is necessary to consider additional movement effects resulting from indirect ocean tidal loading or atmosphere loading.
Examining the need for a public procurement maturity model (PPMM) for infrastructure buyers in a monopsony market structure
Authors: Simionescu Violeta 
Published: July 2016

Abstract
This paper examines the need for a Public Procurement Maturity Model (PPMM) in organizations with the role of road infrastructure buyers under public procurement legislation in a monopsony market structure. The environment used to contextualize the information is Romania and CNADNR (Compania Națională de Autostrăzi și Drumuri Naționale din România).
The literature research, open data as well as my own practical experience are used as entry data for the four parts of the paper: (i) the context leading to the PPMM need identification, (ii) an overview of the existing public (procurement) maturity models; (iii) discussions and (iv) summary, limitations, and outlook.
The paper provides arguments of an upstream intervention in the value chain of road transport infrastructure and highlights the benefits of such an intervention. Elements such as Romanian cultural dimensions, type of market structure or impact of the outcomes of public procurement process for road infrastructure are considered relevant entry data for an intervention which aims to contribute to the improvement of performance at a procurement process level.
The results of this paper serve as a starting point for further reflection on the performance in road infrastructure public procurement area in Romania. In addition to the awareness of the need for an intervention at a contracting authority level, the paper arguments that market structure or national cultural dimensions must be considered as entry data in designing maturity models.
Modeling and simulation of longwall scraper conveyor considering operational faults
Authors: Cenacewicz Krzysztof , Katunin Andrzej 
Published: July 2016

Abstract
The paper provides a description of analytical model of a longwall scraper conveyor, including its electrical, mechanical, measurement and control actuating systems, as well as presentation of its implementation in the form of computer simulator in the Matlab®/Simulink® environment. Using this simulator eight scenarios typical of usual operational conditions of an underground scraper conveyor can be generated. Moreover, the simulator provides a possibility of modeling various operational faults and taking into consideration a measurement noise generated by transducers. The analysis of various combinations of scenarios of operation and faults with description is presented. The simulator developed may find potential application in benchmarking of diagnostic systems, testing of algorithms of operational control or can be used for supporting the modeling of real processes occurring in similar systems.
Language Policy in Switzerland
Authors: Kużelewska Elżbieta 
Published: July 2016

Abstract
Switzerland is often referred to as a success story for handling its linguistic and cultural diversity. Traditionally four languages have been spoken in relatively homogeneous territories: German, French, Italian and Rhaeto- Romanic (Romansh). The first three have been national languages since the foundation of the Confederation in 1848; the fourth became a national language in 1938. In effect, The Law on Languages, in effect since 2010, has regulated the use and promotion of languages and enhanced the status of Romansh as one of the official languages since 2010.
While Swiss language policy is determined at the federal level, it is in the actual practice a matter for cantonal implementation. Article 70 of the Swiss Federal Constitution, titled “Languages”, enshrines the principle of multilingualism. A recent project to create legislation to implement multilingualism across the cantons, however, has failed. Thus Switzerland remains de jure quadrilingual, but de facto bilingual at best, with only a handful of cantons recognizing more than one official language (Newman, 2006: 2). Cantonal borders are not based on language: the French-German language border runs across cantons during most of its course from north to south, and such is also the case for Italian.

AbstractUnderstanding the effect of long-term drainage of peatland areas is helpful in future peatland management and regulations of water conditions. The aim of this work was to assess the current state of fen peatland soils in the Grójecka Valley (eastern part of the Wielkopolskie voivodeship, central Poland), affected by long-term agricultural use (pastures, meadows) since the 1960s and potentially by lignite open pit mining industry (KWB Konin) since 1980s. Field studies were carried out in 2015 in selected fen peatland areas. Soil material for laboratory analysis was collected from genetic horizons from four soil profiles. The surface horizons of studied organic and organo-mineral soils were built with well-developed moorsh material. They were classified as medium moorshiefied – MtII (profile 1, 3 and 4) and strongly moorshiefied – MtIII (profile 2). Obtained results of physical and physico-chemical analysis indicate that long-term peatland utilization connected with potential impact of the lignite mining, transformed mainly the upper horizons of studied organic and organo-mineral soils. However, despite obvious strong human impact on peatlands ecosystems, we cannot exclude the climate variables, what should be confirmed by long-term monitoring program. Furthermore, presented paper indicated that new subtype moorsh-muddy soils (in Polish: gleby murszowo-mułowe) within the type of gleyic soils should be implemented in the next version of Polish Soil Classification.
Estimation of selected properties of forest soils using near-infrared spectroscopy (NIR)
Authors: Kania Mateusz , Gruba Piotr 
Published: July 2016

Abstract
The study was focused on the application of near-infrared spectroscopy (NIR) as a tool for evaluation of selected properties of forest soils. We analysed 144 soil samples from the topsoil of nine plots located in southern Poland. Six plots were established under pine stands, and three plots under oak stands. The NIR measurements were performed using Antharis II FT scanner. On the basis of the spectrum files obtained from scanning of 96 samples and the measurement results obtained for selected properties of the soil samples, we developed a calibration model. The model was validated using 48 independent samples. We attempted to estimate the following properties of forest soils: pH, C:N ratio, the organic carbon content (Ct), total nitrogen (Nt), clay content (Clay), base cation content (BC), cation exchange capacity (CEC) and total acidity (TA). We conclude that estimation of soil properties using NIR method can be applied as additional (to laboratory analysis) or initial assessment of soil quality. Our results also suggest that forest species composition may affect the mathematical model applied to NIR spectra analysis, however, this hypothesis needs some of further investigations.
Elderly Parents, Adult Children and the Romanian Transnational Family: An Intergenerational Solidarity Approach
Authors: Földes Ionuţ 
Published: July 2016

Abstract
Recent demographic changes such as ageing, low-fertility, and large out-migration from Eastern European countries, brought into discussion the vivid question of the future of intergenerational solidarity within families. In the context of increasing geographical mobility of young people in search for better paid jobs, the unmet need for personal assistance among the elderly, the underdeveloped system of care services, Romania knows new dynamics of intergenerational support. Contrary to perspectives that consider spatial proximity between adult children and their elder parents the indisputable enabling factor for intergenerational support transfers (Rossi and Rossi, 1990), emerging literature on transnational families highlights that such tight kinship relations continue to exist even across borders (Baldassar et al., 2007). Using recent data from the nationwide survey “The Impact of Migration on Older Parents Left Behind in Romania” (2011), this paper examines the complex dynamics of intergenerational solidarity involving adult children as transnational migrants and their elder parents who remain at home. The statistical models used indicate the migrants’ role as providers of remittances, but also the ways in which other forms of support are distributed among the dyads. Despite a possible presupposition that parents who were left at home might only be beneficiaries of support, the data show the opposite: elderly persons, depending on their age, were active providers of help as well.
