Long-Run Effects of Catholic Schooling on Wages
Authors: Jha Nikhil , Polidano Cain 
Published: June 2015

Abstract
Previous studies have linked Catholic schooling to higher academic achievement. We add to the literature on Catholic schooling by examining its effect on long-term wages in Australia, independent of effects on academic achievement. Using panel data from the Household Income and Labour Dynamics Australia (HILDA) survey and fixed effects estimation, we find that during the prime-age of a career, wages for Catholic school graduates progress with labor market experience at a greater rate, on average, than wages for public school graduates. Importantly, we find no evidence to suggest that these benefits are peculiar to Catholic schooling, with similar benefits estimated for graduates of independent private schools. These findings suggest that private schooling may be important in not only fostering higher academic achievement but also in better preparing students for a working life.

AbstractRevision surgery of cemented femoral stems in total hip arthroplasty is gaining more and more importance, but cement removal in revision hip arthroplasty may be technically challenging. Conventional manual cement removal can be time consuming and be associated with complications such as cortical perforation, fracture, or bone loss. The aim of this study was to investigate the practicability of computer-navigated cement removal.In anThe mean time for cement removal was 29±5 min for the conventional method and 32±8 min for the freehand-navigated cement removal. Here, excepting the preparatory examinations, the navigated cement removal only took 13±5 min. The measured temperature during polymerization was 36±5°C and during navigated cement removal was 37±8°C. In the distal part of the femur, cement removal was more accurate with the conventional method compared to the navigated one.The freehand-navigated cement removal, with the exception of the preparatory examinations, is time saving compared to the conventional method. However, a potential for technical development especially for the milling device and accuracy exist.

AbstractThe recent revision of ISO15189 has further strengthened its position as the standard for accreditation for medical laboratories. Both for laboratories and their customers it is important that the scope of such accreditation is clear. Therefore the European co-operation for accreditation (EA) demands that the national bodies responsible for accreditation describe the scope of every laboratory accreditation in a way that leaves no room for doubt about the range of competence of the particular laboratories. According to EA recommendations scopes may be fixed, mentioning every single test that is part of the accreditation, or flexible, mentioning all combinations of medical field, examination type and materials for which the laboratory is competent. Up to now national accreditation bodies perpetuate use of fixed scopes, partly by inertia, partly out of fear that a too flexible scope may lead to over-valuation of the competence of laboratories, most countries only use fixed scopes. The EA however promotes use of flexible scopes, since this allows for more readily innovation, which contributes to quality in laboratory medicine. In this position paper, the Working Group Accreditation and ISO/CEN Standards belonging to the Quality and Regulation Committee of the EFLM recommends using an approach that has led to successful introduction of the flexible scope for ISO15189 accreditation as intended in EA-4/17 in The Netherlands. The approach is risk-based, discipline and competence-based, and focuses on defining a uniform terminology transferable across the borders of scientific disciplines, laboratories and countries.

Published: June 2015

AbstractAcute pyelonephritis is a severe disease which is sometimes difficult to recognize based on clinical symptoms and routinely available diagnostic tests, especially in young children. The aim of this study was to assess the diagnostic value of urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a biomarker of acute pyelonephritis.In this case-control study we analyzed 134 children (median age 2.5 years) who were admitted to the Pediatric Clinic of University Hospital Centre Osijek, Croatia. Eighty of them had acute pyelonephritis, while 54 children had febrile state of different etiology including cystitis and they represented the control group. uNGAL, white blood cells, C-reactive protein, urinanalysis, urine culture, kidney ultrasound and a dimercaptosuccinic acid scintigraphic scan were done for each child. uNGAL was measured using chemiluminiscent microparticle immunoassay on ARHITECT i1000SR (Abbott Diagnostics, IL, USA).uNGAL values were significantly higher in children with acute pyelonephritis compared to the control groups (113.6 ng/mL vs. 10.2 ng/mL, p<0.001). A receiver operating characteristic curve comparison was done for tested parameters and encouraging results were obtained for uNGAL (AUC=0.952). A cut-off value of 29.4 ng/mL had 92.5% sensitivity and 90.7% specificity. We showed that uNGAL can also serve in differentiating acute pyelonephritis from cystitis (cut-off 38.5 ng/mL), and for differentiation of cystitis from febrile states with etiology other than urinary tract infection (UTI) (cut-off 20.4 ng/mL).uNGAL can be a useful diagnostic biomarker in acute pyelonephritis in children, but also in differentiating cystitis from febrile states other than UTI.
Multi-scale pin fins: Scale analysis and mathematical optimization of micro-pin fins arranged in rows
Authors: Bello-Ochende Tunde 
Published: June 2015

AbstractThis paper shows the performance of a cylindrical micro-pin fins with multiples-arrays structures for maximum heat transfer. The structures has a varying geometric sizes (diameter, height and spacing). The effects of Reynolds number and thermal conductivity ratio on the optimized geometric configurations and the maximum heat transfer rate is documented. Two design configuration were considered. Scales and computational fluid dynamics analysis shows that the benefits of varying fin height is minimal. Results show that performace is increased when three rows of micro pin fin heat sinks with a reduced degree of freedom (fixed height) when compared to two rows of micro pin fins heat sink for the same amount of material. The optimized diameters of the fins seems to have greatest effect on perfomance of the heat sink.
Associated motion in Mojeño Trinitario: Some typological considerations
Authors: Rose Françoise 
Published: June 2015

AbstractAssociated motion is a very little known category. Markers of associated motion encode, on a lexical verb, a motion event in a temporal relation with the event expressed by the lexical verb (and not just the path, as directionals do). The literature on associated motion is scarce, mostly restricted to Australian and Amazonian languages. The paper builds on the general literature on associated motion as a backdrop to the analysis proper of the data from Mojeño Trinitario, an Arawak language spoken in Bolivia. This paper offers a detailed description of the associated motion markers of Mojeño Trinitario, at the morphological, semantic, and discourse levels. The study is mainly based on textual and elicited data collected in the field. The new insights provided in this paper will contribute to the emerging typology of associated motion.
Eurusd Intraday Price Reversal
Authors: Wiśniewska Marta 
Published: June 2015

Abstract
The study investigates the mean reversion in 1-minute EURUSD. Intraday patters in FX seem of particular interest as more and more trades in the FX market are automated high frequency trades (HFT). The study reveals that the mean reversion is present in the intraday EURUSD. ADF test rejects unit root. The average of the deviation of EURUSD from its (moving) mean is close to zero. Furthermore when short and long positions are simultaneously open, the average maximum return achieved through 24 hour period is similar, providing yet another evidence for mean reversion and lack of weak form of market efficiency.
Organisation of the Analytical, Stoichiometric, and Thermodynamic Information for water Chemistry Calculations
Authors: Földényi Rita , Marton Aurél 
Published: June 2015

Abstract
A common feature of the chemical processes of the hydrosphere and water treatment plants is that essentially the same types of chemical equilibrium reactions occur in both fields. These equilibria could be acid/base, complexation, redox, precipitation, and interfacial processes. Since these reactions may also occur in combination, the aqueous environments are unavoidably multispecies systems. Due to multiple equilibria, the state of aggregation, the state of oxidation, as well as the electric charge of the species may change dramatically. Calculation of the equilibrium concentration of the species is facilitated by the availability of analytical, stoichiometric, and thermodynamic information that are consistently organised into an ASTI matrix. The matrix makes it possible to apply a uniform algebraic treatment for all occurring equilibria even, if later on, further reactions have to be included in the chemical model. The use of the ASTI matrix enables us to set up the necessary mass balance equations and equilibrium relationships, which together form a non-linear system of equations (NLSE). The goal of our paper is to show that the use of the ASTI matrix approach in cooperation with the powerful engineering calculation software, MATHCAD14, results in fast and easy handling of the NLSE-s and, consequently, the calculations of speciation in aqueous systems. The paper demonstrates the method of application in three examples: the calculation of the pH dependence of the solubility of calcite in closed and open systems, the calculation of the pH and pε in a system where acid/base reactions, complexation equilibria, and redox equilibria occur, and a study of adsorption of lead ions on aluminium oxide.
Biological Purification of Chemically Pre-Treated Dairy Wastewater before Discharge into a Municipal Sewage Systems

Published: June 2015

Abstract
Dairy production is one of the most inefficient processes with respect to water usage in the food industry. It was estimated that the production of a litre of milk creates three to four litres of wastewater. Dairy wastewater contains a high amount of dissolved and suspended solids. Moreover, it contains high concentrations of fat, protein, and carbohydrate. Consequently, the dairy wastewater content of organic compounds is high and so is its chemical oxygen demand. The majority of organic compounds are biodegradable with a high biological and chemical oxygen demand ratio. In this work, we examined the biological purification of physico-chemically pretreated wastewater from a Hungarian milk-processing factory before it was discharged into the public sewage system. The chemical oxygen demand of the pre-treated wastewater ranged from 500 to 2500 mg dm-3. We found that it was possible to achieve efficient organic material removal from nutrient-poor wastewater without nutrient dosage contrary to the literature. The activated sludge system manifested efficient organic material removal that required a smaller biological volume. Experiments with biofilms have shown that a thicker biofilm needs more dissolved oxygen, which dictates oxygen input levels to be sufficient for creating an aerobic environment.
Supporting Informed Negotiation Processes in Group Recommender Systems
Authors: Gross Tom 
Published: June 2015

Abstract
Group recommender systems make suggestions to groups of users who want to share experiences or products. Despite their high potential for helping users, GRS face diverse challenges that can be clustered into two groups: predictions and processes. Generating predictions of the goodness of the fit of recommendations to the group has been seen as a core challenge of recommender systems from their beginning, while supporting the processes of discussion for reaching consensus on the item to pick is a more recent challenge. In this paper I report on a base platform for GRS with powerful algorithms for generating and explaining recommendations with high predictions, and an easy and effective process model for GRS.

Numerical Analysis Of Flat Slabs With Spherical Voids Subjected To Shear Force
Authors: Bindea M. , Chezan Claudia Maria , Puskas A. 
Published: June 2015

Abstract
Full flat slabs can be enhanced by using spherical voids to replace the unemployed concrete from the core part of the slab. Therefore we get low self-weighted slabs that can reach a high range of spans, a low material consumption compared to classical solutions used so far. On the other hand, the upsides of these slabs pale against the insecurity in design stage about their punching and shear force behaviour. In this paper it is presented a parametric study about shear force behaviour of flat slabs with spherical voids used in standard condition service. The study was made using the Atena 3D finit element design software, starting form a numerical model gauged on experimental results on real models – scale 1:1. Based on these lab results, the model’s validation was made by overlapping the load – displacement experimental curves on the curves yielded from numerical analyses. The results indicate that under a longitudinal reinforcement rate of lower than 0.50%, flat slabs with spherical voids don’t fail to shear force and over this value the capable shear force decreases in comparison with solid slabs, as the reinforcement rate increases.
Mathematical Modelling Of The Bridges Structural Monitoring II

Published: June 2015

Abstract
We have seen in the previous paper that in the case of resistance elements made of steel, at least in this case study, the structure’s response to strains, in this case sunshine, is uncertain, may or may not be linear. The analysis continues for the four characteristic months of 2013, respectively the second month (February), the fifth (May), the eighth (August) and the event (November), covering the four seasons and approximately the entire range of temperatures to which the resistance elements of the bridge are subject to along a calendar year - case study Incheon Grand Bridge, Seoul, South Korea. The number of data pairs recorded, as we have noted, every 15 minutes, is initially 11,616, being difficult to process. Some software (e.g. Table Curve 2D) can work with a maximum of 3000 data pairs. In what follows we will examine the behaviour of a reinforced concrete element of the North Bridge Gap front line and we will build a mathematical model of its behaviour to sunshine, from the input data, one recording every hours, thus reducing the number of measurements to 2904. The aim is to obtain a mathematical model with a correlation coefficient above 0.9, which is also verified and validated. This model will allow us to calculate the expected position of the sensor mounted on the resistance element for a certain temperature, the degree of confidence of the result, the interval of residual values. Because the history of the evolution of temperatures for each moment analyzed is different it produces different results, but ones that fit the specified regressive mathematical model.
Human Resource Management Practices to Support Emotional Labor in Emergency Response
Authors: Mastracci Sharon 
Published: June 2015

Abstract
Based on a continuing program of research, this paper reveals several organizational measures needed if emotional labor is to be supported, including self-care plans, recruiting for self-awareness, and performance evaluations that capture more than a standard set of knowledge, skills, and abilities. The paper focuses on the experience of emergency responders, who work in extreme conditions that demand extensive emotional labor. Propositions are presented to link human resource management practices and individual and organizational outcomes; propositions that can inform future research and hypothesis testing in this area.
Huntahan* vocab assessment toward enriching mother tongue-based classroom practices
Authors: Cacho Reynald M. , Cacho Lynle C. 
Published: June 2015

Abstract
This two-phase action research examined the profile and knowledge level of Grade III pupils about their knowledge on the distinct local vocabularies in order to formulate enrichment or intervention, to address any deficiency or lack of, and to assess whether such enrichment programs are effective for authentic, localized implementation of the MTB-MLE. The research instruments used in the first phase included survey and vocabulary assessment test. The researchers initially employed descriptive statistics to interpret the result. Majority of the respondents have established residency in Lopez, Quezon for at least four years. All of the pupils speak Tagalog only at home. The first phase of the research revealed that the pupils of Lopez West Elementary School Bldg. 1 performed satisfactorily in the language test. Most of them found that the most difficult words are generally content words. The initial results of this study serve as baseline information implying that the pupils’ level of understanding of the Lopezeños words needs enhancement and/or reinforcements; hence, there is an urgent need to implement the 2nd cycle of this action research. The second phase once implemented seeks to evaluate the effectiveness of the intervention and/or enrichment activities that may guide language teachers in the conduct of classroom-based, culturally sensitive, contextualized language instruction.
The relation of vitamin D status with metabolic syndrome in childhood and adolescence: an update
Authors: Challa Anna S. , Makariou Stefania E. , Siomou Ekaterini C. 
Published: June 2015

AbstractAmong children and adolescents, metabolic syndrome (MetS) is more common than previously believed. Hence, any information on the relation between vitamin D insufficiency/deficiency and insulin resistance (IR) in this population with risk of developing MetS is of great importance. This review analyzes and evaluates the existing evidence from cross-sectional, observational, and retrospective studies concerning the effect of vitamin D insufficiency/deficiency on MetS as a whole or on its various components. Most data show that insufficient vitamin D status is associated with increased prevalence of MetS or its individual components, mainly blood pressure and IR, often independent of overall obesity or abdominal adiposity. The implications of these findings could be associated with increased risk for developing cardiovascular disease and type 2 diabetes mellitus in later life. The very few randomized control trials examining any possible beneficial effects of vitamin D supplementation are also included.

Published: June 2015

Abstract
Extensive use of pesticides in agriculture can lead to contamination of fruit harvests and an increased risk of toxic effects on humans. A total of 123 fruit samples harvested in 2012 in the north-eastern region of Poland were analysed for pesticide residues as part of the national monitoring programme, and as part of research commissioned by private customers. Pesticide residues were found in 64.2% of the samples. There were pesticide residues below the maximum residue level (MRL) in 63 (51.2%) of the samples, while 16 (13%) exceeded MRLs set by Regulation (EC) 396/2005. The gooseberry, currant, and strawberry samples showed the most contamination. The most frequently detected pesticides were dithiocarbamates (54) followed by difenoconazole (22), boscalid (17), and alpha-cypermethrin (15). More than half of analysed samples had multiple residues (up to 8 residues), with multiple residues most common in gooseberry and currant samples. This study shows cases of non-authorised pesticide use by farmers who are trying to protect certain fruit.
Rogowski Coil for Current Measurement in a Cryogenic Environment
Authors: Ma Tao , Dai Shaotao , Zhang Jingye , Zhao Lianqi 
Published: June 2015

Abstract
A Rogowski coil based sensor for current measurement in a cryogenic environment and results of its application for paralleled high temperature superconducting (HTS) coil current sharing are presented. The current sensor consists of a Rogowski coil and an integrator, where the coil output voltage is proportional to the derivative of primary current and the integrator transfers the differentiation to normal state. The Rogowski coil has promising applicability at cryogenic circumstance because its body is made of low temperature materials. The integrator ensures a large bandwidth with feasible magnitude, which is vital for dynamic current measurement during the quench of the HTS coil. The proposed current sensor is used for current sharing measurement of two paralleled Bi2223 HTS coils, and the experimental results show that the measurement precision is better than 0.5%.
