Developing nursing expertise in simulation-based learning environments

The work of nurse anaesthetists is carried out in a highly technological environment, where patient care is provided in close collaboration with other members of hospital staff. The expertise of these nurses and how this is developed is of vital importance. Furthermore, the use of computerised pedagogical tools to support learning within an educational setting is of special interest. The main aim of this paper is to investigate how the use of one of these tools, a simulation based learning environment, can contribute to learning in the domain of anaesthesia care. The study is carried out within the framework of socio-cultural theory. From this perspective, learning is viewed as being situated in communities of practice, where interaction between individuals, and between artefacts and individuals, is considered as central in the learning process. Here, we will present results from a study of how trainee nurse anaesthetists use computer simulations and discuss issues concerning their learning processes. The planning, implementation and debriefing phases of one training session are scrutinised with respect to the framing of problems and implications for learning. The results support the assumption that work in computer based learning environments can influence assessment procedures and decisionmaking skills in significant ways, and that computer-based learning environments provide productive means for goal directed collaborative learning activities.
Transition Modelling on Separated Flow in Turbine Cascade

The work deals with numerical simulation of turbulent flow through turbine cascade by RANS model with model of transition to turbulence. Performance of two transition models is compared. First one is gamma-zeta model based on transition criteria, second one algebraic transition model based on the concept of laminar fluctuations energy (Kubacki, Dick 2016). The criterion for transition in separated state is re-formulated in order to remove stream-wise non-local formulation. The performance of the transition models is observed on the shock wave boundary layer interaction on turbine blade.
1 NUMERICAL SIMULATIONS OF BREAKING SOLITARY WAVES

This paper presents the application of a parallel numerical code to breaking solitary waves impacting a seawall structure. The three-dimensional Navier-Stokes equations are solved in air and water, coupled with a subgrid scale model to take turbulence into account. We compared three numerical methods for the free-surface description, using the classical VOFPLIC and VOF-TVD methods, and an original VOF-SM method recently developed in our numerical tool (Vincent et al. 2010). Some experimental data for solitary waves impinging and overtopping coastal structures are available in literature (Hsiao and Lin, 2010). Solitary waves are often used to model tsunami behaviors because of their hydrodynamic similarities. From a numerical point of view, it allows shorter CPU time simulations, as only one wave breaks. Here we apply the model to simulate three-dimensional solitary waves and compare qualitatively our results with the experimental data. We investigate three configurations of solitary waves impinging and overtopping an impermeable seawall on a 1:20 sloping beach.
with Transaction Cost for Pricing European Options and Hedging

Abstract: In this paper models with transaction costs for pricing of European options using mixed fractional Brownian motion (fbm) and Partial differential equation (PDE) model are considered. Investigation on price sensitivity to volatility and formulation of asymptotic strategy for replicating self financing assets are also made. Simulation experiments for the models are run to obtain the call and put prices using fbm with Hurst parameter 3 H  and the Crank-Nicolson method for the numerical solution to the PDE model. It is found that stock prices increase with time to maturity dates, whereas, the call prices decrease steadily as time approaches maturity dates in conformity with theta hedging strategy.
Mini-review: recent updates on the mathematical modelling of radiation-induced bystander effects

Radiotherapy treatment uses ionizing radiation (IR) in order to kill cancer cells. However, the IR exerted its effects outside the radiation field and causes cell death in healthy cells. This effect namely as radiation-induced bystander effects (RIBE) phenomenon. The scope of the overview of the RIBE phenomenon discussed in this paper includes the RIBE mechanism, danger signaling process, deoxyribonucleic acid (DNA) double-strand breaks (DSBs) damage and the damage repair. This paper extended with the discussion of several mathematical models used to describe the RIBE phenomenon. The discussions towards the mathematical models include the models of signals concentration, the models of bystander effects and the survival fraction model. Mathematical modelling and computer simulation are powerful tools used to understand the biological phenomenon of RIBE. The suitable mathematical model of repair and mis-repair DNA DSBs damage has been briefly reviewed in view of the relevance of this model towards RIBE phenomenon. The outcome of this paper suggested a recommendation for future research on the suitable mathematical model and simulation analysis in describing the complexity of RIBE phenomenon.
Blowflies as vectors of Bacillus anthracis in the Kruger National Park

Anthrax, caused by Bacillus anthracis, is endemic in the Kruger National Park (KNP). The epidemiology of B. anthracis is dependent on various factors including vectors.The aims of this study were to examine non-biting blowflies for the presence of B. anthracis externally and internally after feeding on an anthrax-infected carcass and to determine the role of flies in disseminating B. anthracis onto the surrounding vegetation.During an anthrax outbreak in 2014 in the endemic Pafuri region, blowflies associated with two 2–3-day-old anthrax-positive carcasses (kudu and impala) as well as surrounding vegetation were collected and investigated for the presence of B. anthracis spores.The non-biting blowflies (n = 57) caught included Chrysomya albiceps, Ch. marginalis and Lucilia spp. Bacillus anthracis spores were isolated from 65.5% and 25.0% of blowflies collected from the kudu and impala carcasses, respectively.Chrysomya albiceps and Ch. marginalis have the potential to disseminate B. anthracis to vegetation from infected carcasses and may play a role in the epidemiology of anthrax in the KNP. No B. anthracis spores were initially isolated from leaves of the surrounding vegetation using selective media. However, 170 and 500 spores were subsequently isolated from Abutilon angulatum and Acacia sp. leaves, respectively, when using sheep blood agar.Conservation implications: The results obtained in this study have no direct conservation implications and only assist in the understanding of the spread of the disease.
Control of Small Scale Rotary Wing Unmanned Aerial Vehicle (R-UAV) Using Backstepping

Many conventional flight control designs assume the aircraft dynamics to be linear about some nominal flight condition. But this paper deals with the problem of controlling an aircraft explicitly considering its nonlinear dynamics. Our main tool will be backstepping [4], a Lyapunov based design method that has received a lot of attention in the recent years. Compared to other nonlinear techniques like feedback linearization, backstepping offers a more flexible way of dealing the nonlinearities. Using Lyapunov functions, their influence on the system can be analyzed and stabilized, and thus in a sense, useful nonlinearities can be cancelled or dominated by the control signal. Not having to cancel all nonlinearities means that the resulting control law may be much simpler than if feedback linearization had been used. In this paper, the application is angle of attack and sideslip control. Using inherent characteristics, we will show that despite its nonlinear dynamics the required state of the R-UAV is stabilized around the desired trajectory, regardless of the initial condition. The remainder of the paper is organized as follows- In Section 2, a nonlinear model of the Rotary wing Unmanned Aerial Vehicle (R-UAV) is described and the dynamic equations are transformed into pure-feedback form which is crucial to the backstepping design. In Section 3, the backstepping control law is derived in detail, and in Section 4 the control law is implemented using a generic simulation model of R-UAV.
Predictive and Stochastic Techniques for Software Reduction Orders with Bug Triage

Bugs are extremely basic viewpoints in a software firm. Bug triage is a required advance in a software organization and it can't be maintained a strategic distance from. In bug triage developer ought to be relegated for settling the bug. So existing techniques utilizes content characterization for performing bug triage. In this techniques programmed bug triage is performed. Furthermore, even they perform data diminishment in existing framework which is basic for bug triage. Data lessening is performed utilizing the instance selection and feature selection techniques. Low Scale data impacts the technique of bug triage and furthermore expands the nature of the bug triage. Yet at the same time utilizing the content arrangement for bug triage isn't exceptionally exact. So to enhance the accuracy of bug triage in proposed framework we are utilizing space particular class marks. Utilizing Domain particular characterization the accuracy is enhanced which is appeared in the results.
Spectral emissivity evaluation for materials used in microelectronics

This paper presents emisivity (e) measurements for some materials used in microelectronics, eg. : aluminium, silicon, germanium and diamond-like structures. In this work we emphasise emissivity evaluation for semitransparent and multilayer dielectric materials. The measurement was performed with the use of IR Spectrometer. For every sample we measured the reflected and transmitted energy, and evaluated material constants for various spectral ranges. The results of this work may be useful in calculating heat removal by radiation in microelectronic devices.
Teaching Students With Developmental Disabilities Daily Living Skills Using Point-of-View Modeling Plus Video Prompting With Error Correction

A primary goal of instruction for students with developmental disabilities is to enhance their future quality of life by promoting skill acquisition, which will enable them to live, function, and participate in the community. One instructional method that can help students with developmental disabilities improve independence in performing daily living skills is video prompting (VP). This study investigated the effectiveness of a VP plus error correction procedure on skill acquisition when teaching daily living skills to four adolescents with mild and moderate developmental disabilities. A multiple baseline across participants design demonstrated that all four participants rapidly acquired dish washing skills upon introduction of the intervention. Future research should further explore the efficacy of error correction procedures used with VP and the impact that these procedures have on student learning and skill retention.
THE ECONOMIC CONSEQUENCES OF CROSS-DELISTING: THE IMPORTANCE OF DIFFERENCES IN LEGAL ENVIRONMENTS BETWEEN THE US AND HOME COUNTRIES

The main purpose of this master’s thesis is to examine the economic consequences of crossdelisting. More specifically, this study investigates the effect of a foreign firm being cross-delisted from one of the three major U.S. stock exchanges (NYSE, NASDAQ and AMEX) on information asymmetry and liquidity, taking into account the legal environments of the home countries. I focus on the differences in legal systems between the US and other countries to examine the influences of these differences on the association between cross-delisting, information asymmetry and liquidity. By evaluating the results of this study, I find no evidence to suggest that cross-listed firms that cross-delist from the U.S. stock exchanges face an increase in information asymmetry or a decrease in liquidity. I also find no evidence that the effect is more pronounced for firms originating from countries with a weaker legal environment than the US. Nonetheless, the results indicate that, in general, the difference in the level of legal environment between the US and the firm’s home country is still of importance for investors. This can be used by regulators and other public policy makers to emphasise the importance of continuous improvements in laws, regulations and their enforcements. The findings give also new insights in the behaviour of the key stakeholders and could be used to predict their reactions on future cross-delistings.
Methodological challenges in participation research

Considering that the methods and techniques implemented in social research entail a certain definition of the concepts studied, it seems relevant to reflect on the possibilities of devices other than polls when studying “public opinion” as a sociological concept. Two arguments for such approach can be highlighted: the qualitative and discursive nature of public opinion, and polls’ difficulties for being collectively perceived as a reliable and interesting way to express points of view about public matters. The French CNDP (Commission Nationale du Débat Public) is conceived for encouraging national, regional or local debates about political decisions which involve an important governmental investment. Taking into account that deliberative polling has probably been the most systematized among numerous research devices which have tried to implement the premises of deliberative/participative democracy, we will explore the possibilities of a different and wider representation of “public opinion” from the analysis of the dynamics generated by the institutional device of Public Debate.
Micro Determinants of Albanian Migrant Remittances : Evidence from Thessaloniki

Since 1990, when the fall of communism created a big wave of emigration, remittances to Albania have been a vital source for this country. The aim of this research is to present an outline of the remitting behavior of Albanian migrants based on a sample from the city of Thessaloniki. Material derives from an extensive period of fieldwork research conducted through a set of 200 in-depth interviews with Albanian emigrants living in this city. The main intention of this paper is to better understand the micro determinants that influence remittances. Based on the results of the modeling, we found that income is one of the most important determinants affecting remittances and male migrants are found to remit more than female migrants. Intention of returning home has also an positive effect on remittances while marital status, the family size and the level of education have a negative impact. Age and the number of years spent in the emigration seem to have no significant influence on the remitting behavior.
A Multiple Processing Resource Explanation of the Subjective Dimensions of Operator Workload.

Abstract : Multiple measures of operator workload may dissociate, or fail to agree, for a given task. The goal of this study was to determine which task difficulty (workload) as indexed by attentional resource demand could explain the attendant variance in a second index of workload, subjective ratings. A multiple resource model of processing resources (Wickens, 1980) guided construction of tasks of differential resource demand. These tasks were both performed by subjects and rated according to workload similarity. Scaling and clustering analyses of the similarity data produced subjective dimensions/clusters of workload that were explained in terms of resource demand, task structure, and task characteristics. Data collected to support this analysis - task performance, physiological measures of heart period variability, effort ratings - revealed three primary dissociations. These dissociations were explained by using the parameters of Wickens' multiple resource theory.
A new species of Surdisorex Thomas, 1906 (Mammalia, Soricidae) from western Kenya

The genus Surdisorex represents Kenya's only endemic genus of mammal. It has heretofore included two species from the highlands of central Kenya. Here we add a third species, also from Kenya, based on a specimen from the eri- caceous zone of the eastern slopes of Mt. Elgon. Although this species further aligns Mt. Elgon with the Kenya High- lands, the mammal fauna of Mt. Elgon illustrates a mixture of faunal origins and associations.
University mobility at enrollment: geographical disparities in Italy

Using a micro-dataset of Italian students enrolled at university for the first time in 2008 and derived from the Anagrafe Nazionale degli Studenti (ANS), we model internal student mobility as a function of both individual-level and territorial characteristics. We use multilevel modelling to explicitly account for the hierarchical nature of our data (students nested within Italian districts - NUTS-3 geographic aggregation level) and to understand whether there are significant variations in mobility patterns within and between districts. District differences in student mobility remain significant even after controlling for individual characteristics: this result confirms that the geographical dimension is relevant for student mobility.
Atmospheric Radiocarbon for the Period 1950–2010

We present a compilation of tropospheric 14CO2 for the period 1950–2010, based on published radiocarbon data from selected records of atmospheric CO2 sampling and tree-ring series. This compilation is a new version of the compilation by Hua and Barbetti (2004) and consists of yearly summer data sets for zonal, hemispheric, and global levels of atmospheric 14C. In addition, compiled (and extended) monthly data sets for 5 atmospheric zones (3 in the Northern Hemisphere and 2 in the Southern Hemisphere) are reported. The annual data sets are for use in regional and global carbon model calculations, while the extended monthly data sets serve as calibration curves for 14C dating of recent, short-lived terrestrial organic materials.
splatche: a program to simulate genetic diversity taking into account environmental heterogeneity

We present a program called SPLATCHE (SPatiaL And Temporal Coalescences in Heterogeneous Environments) to simulate the molecular diversity of samples of genes in an environmentally heterogeneous world. Simulations are performed by, first, simulating the colonization of the world using environmental information to constrain migrations and local densities. These simulated densities and migration rates recorded over time and space are then used to simulate genetic diversity under a coalescent framework. The program thus virtually allows the translation of ecological information into molecular diversity, a novel approach that can be used to study the effect of climatic change on genetic diversity.
Use web resources to construct ontology concept hierarchy

Domain terminology with high quality are the fundamental component in ontology construction and domain terminology automatic extraction is the basis of domain ontology construction. Proposed an approach of achieving domain concepts hierarchies from the Web data. Used the clue words to product queries containing hierarchical relation to get corpus rich in concepts hierarchical relation through the search engine from Web. Then we got target concepts explanation from the online encyclopedia of knowledge corpus such as Wikipedia. By combining the previous two corpus with the domain news documents and HowNet, we constructed the concepts graph model. After applying pruning algorithm on the graph, we proposed a modified hierarchical concepts tree building method. Experimental data on auto car proved the efficiency of the proposed method.
Aerobic conditions and antioxidative system of Azolla caroliniana Willd. in the presence of Hg in water solution

Heavy metals are among the toxic substances for plants. Their presence causes a state called "heavy metals stress" which manifests itself by many physiological changes in plants. One of them is the formation of reactive oxygen species (ROS) which are scavenged by enzymatic and non enzymatic defending systems. The physiological responses of aquatic fern Azolla caroliniana Willd. at different mercury concentrations was investigated. During 9 days of the experiment under laboratory conditions, Azolla caroliniana was cultivated on medium enriched in 1, 20 and 30 mg Hg(II) dm-3. In this time the oxygen diffusion rate (ODR) and the superoxide dismutase activity (SOD) were determined. A strong release of oxygen by the fern roots (ODR up to 50 ^g m-2s-1) was recorded. It was related with an increase in SOD activities (up to 4000 units) above control values, which testifies to the existence of a defense reaction of A. caroliniana to the heavy metal stress.
Diagnostic spectroscopy of G-band brightenings in the photosphere of the sun

A detailed analysis of high-resolution spectra obtained in three different wavelength regions (at 430 nm, 526 nm and 569 nm) of G-band bright points in the solar photosphere is presented. They show an average intensity contrast of 11% with respect to the "quiet" sun reference. The CH lines are weakened in the bright point interior. The atomic lines, too, e.g. the Fe I line at 569.15 nm, weaken in the bright point interior. In contrast thereto, the absorption line of single ionized iron at 526.48 nm remains almost constant between bright point interior and the immediate surroundings. Line-of-sight velocities show a stronger downflow within bright points than in the close environment. A net downflow relative to the intergranular sur- roundings of around 80 m/s is measured. Filling factors are calculated from a comparison with synthesized spectra for different flux tube models and are used to estimate the "true" velocity in bright points with respect to their immediate surroundings. We obtain up- and downflows in the order of one km s −1 , in agreement with the magneto-convective picture of the formation and dispersal of magnetic flux tubes. From the different behavior of the metallic lines and the CH lines we conclude that the line-weakening process that leads to the G-band bright points is mainly due to hot-wall radiation. This confirms that these bright points are indeed magnetic flux elements.
Factors Affecting the Intake of Dietary Fiber in the United States Diet

The 2010 USDA Dietary Guidelines for Americans recommended that individuals consume around 25 grams of dietary fiber per person per day. Yet despite these recommendations, consumers do not purchase enough foods high in dietary fiber. To investigate the factors behind this behavior, we perform an empirical analysis using Nielsen Homescan data for 2011 with a sample of 62,092 households from across the United States. This research contributes to the literature by simultaneously investigating per capita purchases of products containing fiber: bread, pasta, tortilla, and fresh produce (fruit and vegetables combined). We perform the estimation using a seemingly unrelated regression framework with a Tobit model setting for each equation in order to account for the censored nature of the available data. Preliminary results suggest that individuals that use coupons generally report purchasing more fiber per capita. Those living below 130 percent and below 185 percent of the federal poverty level purchase less fiber per capita from bread and pasta. For these individuals, the fiber purchased from produce is not significantly different from the individuals above the cutoff levels. Those with a higher income or education report more consumption of fiber per capita from produce and less from bread and pasta.
