Ab initio study of the stability of intrinsic and extrinsic Ag point defects in 3 C e SiC

We have systematically investigated the energetics and stability of Ag atom in 3CeSiC with various charge states using first-principles calculations within large supercells. Up to 18 Ag-defect configurations have been examined, including substitutionals, interstitials, and vacancy-based complexes. A general trend is that the formation energy of Ag-defect complexes is generally lower than interstitial typed defects. With the lowest formation energy, the configuration with Ag_TSi-VC3þ turns out to be the most stable one. It has also been found a neutral Ag is more likely to substitute a silicon lattice site with a nearest carbon vacancy, thus forming an AgSi-VC pair. All these data are important inputs in the next coarser-level modeling to understand the Ag migration in and release from 3CeSiC under both thermal and radiation conditions. © 2018 Elsevier B.V.

Wage Discrimination Against Immigrants in Austria?

This paper analyses wage discrimination against immigrants in Austria using combined information from the labor force surveys and administrative social security data. We find that immigrants experience a wage disadvantage of 15 percentage points compared to natives. However, a substantial part of the wage gap can be explained by differences in human capital endowment and job position. Decomposition methods using quantile regressions show larger discrimination in the upper part of the wage distribution. Moreover, we do not find any evidence for wage assimilation of immigrants in Austria.

Financial Development and Poverty Reduction: Exploring the Links between the Issues Using Evidence from Bangladesh

This paper estimates the impact of financial development and financial instability on poverty reduction. From a time series data set of Bangladesh in the period between 1974 and 2013, this study finds a significant and theoretically meaningful relationship between the issues. Results suggest that financial development reduces poverty directly by providing greater credit access along with savings opportunity for the poor and indirectly via promoting economic growth. Notwithstanding the positive impacts of financial development on poverty reduction, financial instability which arises alongside financial development is adverse to poverty reduction process. The more interesting finding is that, with comparing to the findings of similar studies, the private credit ration has substantially stronger impact on the income of the poor. And it may be for the presence of ample micro-credit programs in Bangladesh.
PHL 1445: an eclipsing cataclysmic variable with a substellar donor near the period minimum

We present high-speed, three-colour photometry of the eclipsing dwarf nova PHL 1445, which, with an orbital period of 76.3 min, lies just below the period minimum of ~82 min for cataclysmic variable stars. Averaging four eclipses reveals resolved eclipses of the white dwarf and bright spot. We determined the system parameters by fitting a parameterised eclipse model to the averaged lightcurve. We obtain a mass ratio of q = 0.087 +- 0.006 and inclination i = 85.2 +- 0.9 degrees. The primary and donor masses were found to be Mw = 0.73 +- 0.03 Msun and Md = 0.064 +- 0.005 Msun, respectively. Through multicolour photometry a temperature of the white dwarf of Tw = 13200 +- 700 K and a distance of 220 +- 50 pc were determined. The evolutionary state of PHL 1445 is uncertain. We are able to rule out a significantly evolved donor, but not one that is slightly evolved. Formation with a brown dwarf donor is plausible; though the brown dwarf would need to be no older than 600 Myrs at the start of mass transfer, requiring an extremely low mass ratio (q = 0.025) progenitor system. PHL 1445 joins SDSS 1433 as a sub-period minimum CV with a substellar donor. These existence of two such systems raises an alternative possibility; that current estimates for the intrinsic scatter and/or position of the period minimum may be in error.
Balance sheet versus earnings conservatism in Europe

In this study we extend prior research on the international analysis of accounting conservatism (Joos and Lang, 1994; Ball et al., 2000; Giner and Rees, 2001), by examining the level of accounting conservatism across eight European countries (United Kingdom, Germany, France, Switzerland, the Netherlands, Italy, Spain and Belgium), and assessing the statistical significance of the differences among them. The definitions of conservatism that we use are, on the one hand, the Feltham and Ohlson (1995) definition, which implies a persistent understatement of book value of shareholders' equity (balance sheet conservatism). On the other hand, we use the one proposed by Basu (1997), that is, a timelier recognition of bad news in earnings relative to good news (earnings conservatism). We also address the possible scale problems of the models used to measure balance sheet conservatism. Finally, we check whether our comparative results could be influenced by a different sample composition in each country. Our results show that there are both balance sheet and earnings conservatism practices in all countries under study. In addition, while continental countries show larger balance sheet conservatism, differences in earnings conservative practices between countries are not that pronounced, although they tend to be larger in the UK. We also find that the existence of balance sheet conservative practices is associated with reduced levels of earnings conservatism, which is consistent with the results in Pope and Walker (2003).
Analysis of complex sentiment on social networks

The main goal of sentiment analysis (also known as opinion mining) on social networks is to analyze and determine sentiment of the author publishing on social networks using text mining and machine learning technologies. Although basic sentiment (positive, negative, neutral) analysis is an interesting and important topic and well covered in research, complex sentiment analysis, like detection of sarcasm, judgement, aggression or disappointment, still poses a research challenge from linguistic and technical point of view. Another topic of our interest, which is also challenging, is detection and analysis of sentiment changes in time. This paper presents an overview of recent research on complex sentiment analysis and sentiment dynamics analysis problems. Past work is critically evaluated and recommendations for future research is proposed.
A NOVEL APPROACH TO OPTIMIZE GRINDING CIRCUITS- MODELLING STRATEGY TO MONITOR BALL MILL PARTICLE SIZE DISTRIBUTION DATA AT LAKAN PLANT

Abstract– Online monitoring and control of size distribution in any grinding circuit is a vital task in mineral processing plants. Flotation process efficiency depends on the size of feed materials and also fraction of the fine particles e.g. -38 microns. This paper presents a new approach to monitor the size distribution of Lakan Pb/Zn flotation circuit in Iran. A software monitoring size distribution has been developed, based on two main parameters named "n" which is reduction ratio in the mill and "b" which comes from Guadin equation, i.e. b aD W = . "n" depends on mill characters and feed function while "b" depends on ore, instruments, and other properties. Liberation and size fraction studies showed that the d80 of ground material should be -74 microns and weight of passing 38 microns materials should be 35-40%, which is the optimum condition for the flotation recovery. Finally, results obtained from ball mill circuit for "n" and "b" indicated that these parameters were equal to "nBall Mill=80-87" and "bBall Mill=0.84-1.1" at optimum condition. Under this condition, flotation recovery increases up to 75%, which is practically confirmed in Lakan flotation plant.
Treatment of water contaminated with Pb(II) and Cd(II) by adsorption on kaolinite, montmorillonite and their acid-activated forms

Removal of Pb(II) and Cd(II) from spiked water samples by adsorption on clays was studied in this work as a model for water treatment. Kaolinite and montmorillonite were used as the clay adsorbents and they were further activated by treating with 0.25 M H 2 SO 4 . All the adsorbents were characterized with respect to surface area, cation exchange capacity and structural features as revealed with XRD and FTIR measurements. The adsorption experiments were carried out in a batch process with the variation of initial concentration of metal ions, amount of clay, pH, time and temperature. The adsorption was favoured at higher pH. The clay-Pb(II) interactions attained equilibrium at 180 min, whereas clay-Cd(II) system required 240 min to reach the same. Both the systems follow second order kinetic model. Montmorillonite and its acid-treated form had better adsorption properties. The Langmuir monolayer capacity varied from 11.1 to 34.0 mg/g and from 9.9 to 33.2 mg/g for Pb(II) and Cd(II) ions, respectively depending on the clay. Pb(II) adsorbed exothermally while the processes were endothermic with Cd(II). Kaolinite, montmorillonite and their acid activated forms have good potential for taking up Pb(II) and Cd(II) from aqueous medium.
Social fields and natural systems : Integrating knowledge about society and nature

Sustainability science is a wide and integrative scientific field. It embraces both complementary and contradictory approaches and perspectives for dealing with newer sustainability challenges in the context of old and persistent social problems. In this article we suggest a combined approach called social fields and natural systems. It builds on field theory and systems thinking and can assist sustainability scientists and others in integrating the best available knowledge from the natural sciences with that from the social sciences. The approach is preferable, we argue, to the various scientific efforts to integrate theories and frameworks that are rooted in incompatible ontologies and epistemologies. In that respect, this article is a critique of approaches that take the integration of the social and natural sciences for granted. At the same time it is an attempt to build a promising alternative. The theoretical and methodological pluralism that we suggest here, holistic pluralism, is one way to overcome incommensurability between the natural and the social sciences while avoiding functionalism, technological and environmental determinism, and over-reliance on rational choice theory. In addition, it is a basis for generating better understandings and problem solving capacity for sustainability challenges. We make three contributions. First, we identify important reasons for the incommensurability between the social and natural sciences, and propose remedies for overcoming some of the difficulties in integrative research. Second, we show how sustainability science will benefit from drawing more deeply on—and thus more adequately incorporate—social science understandings of society and the social, including field theory. Third, we illustrate the suggested approach of social fields and natural systems in two examples that are highly relevant for both sustainability science and sustainability itself, one on climate change adaptation and one on geoengineering.

A Taxonomy of the Machine Learning Algorithms

Machine learning methods often improve their accuracy by using models with more parameters trained on large numbers of data sets. Building such models on a single machine is often impractical because of expansive measure of calculation required. In this paper, we focus on developing a general technique for parallel programming of some of the machine learning algorithms. Our work is in distinct to the tradition in machine learning of designing ways to speed up a single algorithm at a time . We show that algorithms that fit the Statistical Query model can be composed in a certain “summation form,” which allows them to be effectively parallelized. The central idea of this approach is to allow a future programmer or user to accelerate machine learning applications.
Epidemiology of Pseudomonas aeruginosa in Intensive Care Unit and Otolaryngology Department of a Tunisian hospital

Ninety four clinical isolates of Pseudomonas aeruginosa cultured from patients admitted to the Intensive Care Unit (ICU) (N= 37) and Otolaryngology (ORL) (N= 57) during one year (2001-2002) at the Rabta hospital (Tunisia) have been investigated by using serotyping, pyocintyping, drug susceptibility, M13-PCR and PFGE typing. Result shown that most of the isolates at the ICU belonged to serotype O:12 (11/37) that showed high resistance to commonly used antimicrobials (β-lactamins, aminosids, and quinolone) and a predominance for pyocinotype P10. Despite the frequent occurrence of identical serotypes and pyocinotypes, most of the isolates represent unique RAPD-M13 genotype (88/94). PFGE typing detected three distinct clusters amongst the O12 isolates, suggesting a clonal relatedness among multiresistant O12 isolates. This study illustrates the importance of phenotypic and genotypic epidemiological surveillance of predominant O12 serotype clones in such service in local hospital. Key words: Pseudomonas aeruginosa, epidemiology, clonal diffusion, multidrug resistance.
A Hierarchical System Design for detection of Glaucoma from Color Fundus Images

Glaucoma is an eye disorder which is prevalent in the aging population and causes irreversible loss of vision. Hence, computer aided solutions are of interest for screening purposes. Glaucoma is indicated by structural changes in the optic disc (OD), loss of nerve fibres and atrophy of the peripapillary region of the OD in retina. In retinal images, most of these appear in the form of subtle variation in appearance. Hence, automated assessment of glaucoma from colour fundus images is a challenging problem. Prevalent approaches aim at detecting the primary indicator, namely, the optic cup deformation relative to the disc and use the ratio of the two diameters in the vertical direction, to classify images as normal or glaucomatous. We explore the use of global motion pattern-based features to detect glaucoma from images and propose an image representation that serves to accentuate subtle indicators of the disease. These global image features are then used to identify normal cases effectively. The proposed method is demonstrated on a large image dataset consisting of 1845 images annotated by 3 medical experts. The global approach is extended to detect atrophy and two hierarchical system designs are proposed. In the first design, only global analysis is used, while in the second both global and local analysis are employed. In the first design, the first stage is based on features capturing information mainly of primary indicators while the second stage is based on features extracted for detecting atrophy (secondary visual indicator). The second design attempts to combine the strengths of global and local analysis of the OD region. Global features are used to remove as many normal cases as possible in the first stage and local features are used to perform a finer classification in the second stage. This system has been tested on 1040 images with ground truth collected from 3 glaucoma experts. The results show the hybrid approach offers a good solution for glaucoma screening from retinal images
Transepithelial Cytophagy by Trichoplax adhaerens F. E. Schulze (Placozoa) Feeding on Yeast

After accidental observations of unicellular algae trapped in the intermediate layer of Trichoplax, dead yeast cells were offered systematically as a food. Some of them could be found several hours later engulfed by the big tetraploid fibre cells closely beneath the dorsal epithelium of the animal. This thin epithelial sheet not only allows the expulsion of accumulated waste substances by temporal separation of the cell connections but obviously gives also access to food particles collected previously on the dorsal surface by flagellar movements. Thus, the uppermost cell layer of Trichoplax permits the passage of corpuscles of limited size between its cells.
CaRiSMA 1.0: Cardiac Risk Self-Monitoring Assessment

Background : Scattered analysis of some cross country skiing techniques is present in the literature. Objective : To provide an exhaustive classification and systematic overview of techniques in cross country skiing. Method : This paper classifies six techniques for skate skiing (gliding diagonal skate skiing G1, paddling G2, double dance G3, two skate G4, marathon skate, combiskate G5), four techniques for classical skiing (running diagonal stride RUN DS, diagonal stride DS, double poling kick DK, and double poling DP), five techniques for both skate skiing and classical skiing (herringbone HB, side-stepping G6, low tuck G7, plowing, skidding), and five techniques for steep terrain ski mountaineering. Classification occurs according to degrees of inclination of the terrain, speed ranges, whether the technique is propulsive or for downhill velocity control/turning, frequency of time applied, and literature references. Furthermore, techniques depend on snow conditions, friction, competition, training, wind, positioning within a race, the skier’s expertise, exhaustion level, acceleration, deceleration, etc. Results : Techniques can influence who wins races in cross-country skiing. Reasons for technique changes are provided, exemplified with technique changes through terrains with different inclines. Literature references are given for inclines and speeds for the various techniques. Conclusion : Essential for maturing skiers are the frequency and quality by which the six techniques for skate skiing, four techniques for classical skiing, and five techniques for both styles except mountaineering, are trained, when to use them, how and in which sequence they are introduced, and adequate supplementary training (e.g. crunches for double poling DP). A research program is sketched.
- 1-Achieving Academic Success After School : A Randomized Evaluation of the Higher Achievement Program 1 September 2011

We conduct a RCT of a high-quality, comprehensive, and time-intensive after-school and summer supplemental-education program targeted at students in middle school. We find that the program significantly increases students’ problem solving and reading comprehension scores two years after baseline. The program also causes students to reassess their perceptions of their own academic abilities. We find no evidence that the program improves test scores after one year or that the program changes students perceptions of the support they receive from adults or their peers. We also do not find that the program improves students’ test scores or other outcomes over the summer of 2010. However, their test scores also do not decrease over the summer as they do for many students. Finally, we find evidence that the program increases students’ desire to attend competitive area high schools rather than their local public schools. Surprisingly, the program also increases the rate at which students report misbehaving. 1 This study could not have been completed without the assistance of many individuals. We are, of course, grateful to the parents and youth who took the time to provide the data used in this manuscript. At Higher Achievement, Edsson Contreras, Maureen Holla, Lynsey Jeffries, Nicole Levine, Richard Tagle, and Gail Williams all provided significant help with recruitment and other aspects of the study. Annelies Raue provided exceptional assistance in conducting the presented analyses.

Innovative Culture, Management Control Systems and Performance in Young SMEs

We identify organizational culture and assess the relationship between organizational culture, management control systems (MCS) use and their effects on performance. With this purpose, we carry out an empirical analysis on a sample of 89 young SMEs. Results show that young firms’ predominant culture is clan, whereas adhocratic culture is less relevant. Additionally, we found some evidence that the innovative culture (mix of clan and adhocratic culture) and the use of MCS have positive effect on firm performance.
Evaluations of Three Bacillus thuringiensis Against Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in Egypt

The role of three microbial control agents Bacillus thuringiensis Diple (2X); B.t kurstaki HD-73 and B.t kurstaki HD-234 were tested against tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), which infect plants under laboratory, green house and field conditions.
