CD-62°1346: an extreme halo or hypervelocity CH star?

Context. High-velocity halo stars provide important information about the properties of the extreme Galactic halo. The study of unbound and bound Population II stars permits us to better estimate the mass of the halo. Aims. We carried out a detailed spectroscopic and kinematic study and have significantly refined the distance and the evolutionary state of the star. Methods. Its atmospheric parameters, chemical abundances and kinematical properties were determined using high-resolution optical spectroscopy and employing the local-thermodynamic-equilibrium model atmospheres of Kurucz and the spectral analysis code moog. Results. We found that CD-62 ◦ 1346 is a metal-poor ([Fe/H] = −1.6) evolved giant star with Teff = 5300 K and log g = 1.7. The star exhibits high carbon and s-element abundances typical of CH stars. It is also a lead star. Our kinematic analysis of its 3D space motions shows that this star has a highly eccentric (e = 0.91) retrograde orbit with an apogalactic distance of ∼100 kpc, exceeding by a factor of two the distance of the Magellanic Clouds. The star travels with very high velocity relative to the Galactocentric reference frame (VGRF = 570 km s −1 ). Conclusions. CD-62 ◦ 1346 is an evolved giant star and not a subgiant star, as was considered earlier. Whether it is bound or unbound to the Galaxy depends on the assumed mass and on the adopted Galactic potential. We also show that the star HD 5223 is another example of a high-velocity CH star that exceeds the Galactic escape velocity. Possible origins of these two high-velocity stars are briefly discussed. CD-62 ◦ 1346 and HD 5223 are the first red giant stars to join the restricted group of hypervelocity stars.
Formulation and Evaluation of Fast Dissolving Tablets using Solid dispersion of Clopidogrel

The present investigation was aimed to formulate and evaluate of fast dissolving tablets of clopidogrel bisulphate solid dispersion. The solid dispersion was prepared by fusion method using PEG 6000 as carrier in various ratios. The physio-chemical characterization of solid dispersion was carried out by various parameters like drug content, dissolution study and Differential Scanning Calorimetry. The optimized solid dispersion of clopidogrel bisulphate was used in the preparation of fast dissolving tablets by direct compression method with varying concentrations of superdisintegrants like crospovidone, crosscarmellose sodium and sodium starch glycolate. The formulations were further evaluated for pre & post compression parameters and in vitro dissolution studies. The study reveals that the formulation F3 (10% of cross povidone) is found to be the optimized formulation with 99% drug release in 60 minutes in comparison with other super disintegrants. The kinetics study shows that the fast dissolving tablet formulation followed Higuchi model explaining the diffusion controlled release mechanism.
Why the Rich Drink More but Smoke Less: The Impact of Wealth on Health Behaviors

Wealthier individuals engage in healthier behavior. This paper seeks to explain this phenomenon by developing a theory of health behavior, and exploiting both lottery winnings and inheritances to test the theory. It distinguishes between the direct monetary cost and the indirect health cost (value of health lost) of unhealthy consumption. The health cost increases with wealth and the degree of unhealthiness, leading wealthier individuals to consume more healthy and moderately unhealthy, but fewer severely unhealthy goods. The empirical evidence presented suggests that differences in health costs may indeed provide an explanation for behavioral differences, and ultimately health outcomes, between wealth groups.
Robustness and Idealizations in Agent-Based Models of Scientific Interaction

The article presents an agent-based model (ABM) of scientific interaction aimed at examining how different degrees of connectedness of scientists impact their efficiency in knowledge acquisition. The model is built on the basis of Zollman’s ([2010]) ABM by changing some of its idealizing assumptions that concern the representation of the central notions underlying the model: epistemic success of the rivalling scientific theories, scientific interaction and the assessment in view of which scientists choose theories to work on. Our results suggest that whether and to what extent the degree of connectedness of a scientific community impacts its efficiency is a highly context-dependent matter since different conditions deem strikingly different results. More generally, we argue that simplicity of ABMs may come at a price: the requirement to run extensive robustness analysis before we can specify the adequate target phenomenon of the model.1 1.

Key Determinants of Waste Separation Intention among Students on Campus

This study aims to identify the key determinants of waste separation intention among the students in Universiti Teknologi Malaysia (UTM). As reported in World Bank Report, generation of global municipal solid waste are approximately 1.3 billion tonnes per year, and it will increase approximately 2.2 billion tonnes per year by 2025. Similar trend in Malaysia which approximately eight million tonnes of municipal solid waste is produced daily. Upward trend of the solid waste generated is contributed by various forces including growth, increase of population, residents attitude and rapid urbanisation in the country. Considering the negative impacts from increase of waste generated in the country such as environmental degradation, separate the waste at its source can increase recycling rate and hence reduce waste generation. In the 11 th Malaysia Plan, the government has urged the nation to actively practice waste separation. Understanding the determinants influencing waste separation behaviour can lead to effective waste reduction among the targeted group. This study adopted the Theory of Planned Behaviour as the fundamental framework. The key determinants of waste separation behaviour are attitude, subjectives norm, and perceived behavioural control. An elicitation survey has been conducted to explore the students’s beliefs relative to the waste separation behaviour. The empirical data collected were analysed using structural equation modelling (SEM) assisted by SmartPLS software. The result shows that only determinants are significant towards intention which are attitude and Perceived Behavioural Control while Subjective Norm is not. The results of the study is significance to the organisation as identification of the determinants that influence waste separation intention contributes to a more focused waste separation programme that allign to Malaysia’s objective towards a sustainable developing country.

Empirical Evidence of Relationship of Features of Firms and Internet-based Financial Reporting

Objective: The evolution in communication and the development of global market lead to creation of new financial opportunities in the world. In this study, investigation on the level of information disclosure through Internet, as in the website of listed firms in Tehran stock exchange (TSE) and correlation with the firm's features such as the industry type, firm size, profit, products' importance, processes, competition (environmental stress) and electronic communication with clients and beneficiaries has been attempted. Methods/Statistical analysis: Initially, a check list based on 84 previous researches, was prepared. The required information was collected through the website of listed firms in industries during 15 May to 20 June 2012 and the data recorded and analyzed in Excel spreadsheet, as the dataset. This information along with financial statements of firms, from automotive industries, chemical industries, banks, investment and medicine products, were processed and analyzed using regression model, concomitant with investigating hypotheses. This input data for statistical model was utilized for the research hypotheses. Finally the data was processed using SPSS software. Conclusion/Application: The results show that the studied companies tend to disclose non-financial information rather than financial information. Also there is a significant and positive relationship between firm size and nature of industry with Internet-based financial reporting. In other side there is a significant inverse relationship between profit and competition with Internet-based reporting and there is no significant relationship between the importance of products, services and electronic communication with clients and Internet-based reporting.
Is profitability a good proxy for efficiency? Evidence from the subsector of tour operators

Abstract The goal of the paper is to evaluate the economic efficiency of tour operators in the Czech Republic in the period 2007-2014 using data envelopment analysis (DEA) models and prove the link between economic efficiency and profitability and to find out if profitability is a good proxy for economic efficiency. Data was exported from the database Albertina CZ Gold Edition. We calculated the efficiency score using CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes and Cooper) models based on 3 inputs and 1 output. In the years 2007 to 2010, the efficiency score of almost all the companies was higher than 0.5; however, in years since 2011, we revealed significant differences in the efficiency of individual firms and only about 40 percent of tour operators achieved an efficiency score higher than 0.5. Using Pearson and Spearman correlation coefficients, our findings show that, in the case of the Czech tour operator market, profitability ratios do not correspond with firm efficiency. Profitability ratios are not a good proxy for economic efficiency and should not be used as the only firm criterion of performance.
Validation of macroscopic maturity stages according to microscopic histological examination for European anchovy

The identification and classification of macroscopic maturity stages plays a key role in the assessment of small pelagic fishery resources. The main scientific international commissions strongly recommend standardizing methodologies across countries and scientists. Unfortunately, there is still a great deal of uncertainty concerning macroscopic identification, which remains to be validated. The current paper analyses reproductive data of European anchovy (Engraulis encrasicolus L. 1758), collected during three summer surveys (2001, 2005 and 2006) in the Strait of Sicily, to evaluate the uncertainty in the macroscopic maturity stage identification and the reliability of the macroscopic adopted scale. On board the survey vessels, the maturity stage of each fish was determined macroscopically by means of an adopted maturity scale subdivided in six stages. Later, at the laboratory, the gonads were prepared for histological examination. The histological slides were analysed, finally assigning the six maturity stages for macroscopic examinations. A correspondence table was obtained with the proportion and number of matches between the two methods. The results highlight critical aspects in the ascription of macroscopic maturity stages, particularly for the present research aim. Different recommendations were evaluated depending on the scope of the study conducted on maturity (e.g. daily egg production, fecundity and maturity ogive computation). The most interesting results concern the misclassification of stage IV and stages III and V (the most abundant), which confirms their macroscopic similarity. Although the results are based on a small number of samples, the advantages and disadvantages of macroscopic and histological methods are discussed with the aim to increase the accuracy of correct identification and to standardize macroscopic maturity ascription criteria.
Influence of ligand positional isomerism on the molecular and supramolecular structures of cobalt(II)-phenylimidazole complexes.

In a study to evaluate the impact of flexible positional isomeric ligands on the coordination geometry and self-assembly process of 3d metal complexes, the synthesis of eight new cobalt(II) complexes with the 2-phenylimidazole (LH) and 5-phenylimidazole (L'H) ligands has been carried out. A variety of parameters/conditions have been probed using the general CoII/X-/LH or L'H (X- = Cl-, Br-, I-, NO3-, NCS-, ClO4-, SO42-) reaction system. Interestingly, X-ray analyses reveal two distinct groups of complexes: reactions with LH only lead to tetrahedral or quasi-tetrahedral complexes {i.e. [CoCl2(LH)2] (1), [CoI2(LH)2] (2), [Co(NO3)2(LH)2] (3), [Co(NCS)2(LH)2] (4)}, whereas L'H favours octahedral coordination {i.e. [Co(L'H)4(MeCN)(H2O)]I2 (5), [Co(L'H)4(MeCN)(H2O)](NO3)2 (6) and [Co(NCS)2(L'H)4)]·2MeOH (7·2MeOH)}. A tetrahedral [Co(NCS)2(L'H)2)] (8) complex was also concurrently isolated with complex 7. The effects of the positional isomeric ligands LH and L'H and of the coordinated inorganic anions on the stoichiometry and packing arrangements of the complexes are thoroughly discussed. The supramolecular assembly is firmly directed, in all types of complexes, by robust N-H.X (X = Cl, I, O or S) motifs, leading to varying dimensionalities (1D, 2D or 3D) and packing arrangements. The formation of these motifs has been activated by choosing appropriate anions X, acting as terminal ligands or counterions. At a second level of organization, additional subordinate C-H.X (X = Cl, I, O or S), C-H. π and π. π intermolecular interactions complement the rigidity of the complexes' packing towards compact 3D assemblies. Hirshfeld surface analyses provided insight into the intermolecular interactions, allowed quantification of the individual contact types and comparison between the complexes.
Leaf, Anthocyanin, and Protein Production of Talinum triangulare Jacq. Willd with Various Rates of P Fertilizer

The effect of P fertilizer rates on growth and production parameters of waterleaf [Talinum triangulare (Jacq.) Willd] were studied over two months (February-April 2010) in Bogor. Treatments of fi ve P-rates (0, 200, 400, 600, and 800 kg SP- 18 ha-1) were laid out in a randomized complete block design with three replications. Generally, the effect of P fertilization in waterleaf was mostly prominent at 8th week after planting (WAP). The increase of P rates increased leaf area, leaf fresh weight, edible part (shoot weight), and protein production; but decreased anthocyanin production. These results suggested that to produce high protein and anthocyanin, waterleaf must be fertilized with 400 kg SP-18 ha-1; and P fertilizer must be applied at least two weeks before planting. Keywords: inorganic fertilizer, phosphorus, portulacaceae, secondary metabolite
Comparison of actual (measured) weights and heights with the standard formula methods of estimation among children in Enugu

Background : In paediatric practice, weight and height are required for therapeutic and diagnostic interventions. In some circumstances actual anthropometric measurements are not possible and estimates are used. Several formulae are in use for weight and height estimations. The adequacy of these estimates has not been tested for our children. The aim of the current study was to compare the adequacy of formula methods of weight and height estimation with measured values in children. Materials and Methods: This was a comparative observational study. Children who met the inclusion criteria were selected consecutively and studied over a two month period using a semi-structured questionnaire. Weight and height of each child were measured and recorded to the nearest 0.1kg and 0.1cm respectively using standard protocols. Weight and height for age were also estimated using the universally accepted formulae. Data were analyzed using SPSS 19.0. Paired t- test was used to compare the means of actual and estimated weights and heights according to age. The level of significance was set at p<0.05. Results : A total of 370 children were studied. They were aged one year two months to 12years. Among children . 2 years the measured weights and estimated values showed no significant difference. However, in children 3-5years, the estimated weights were significantly lower than the measured weights. There was no consistent relationship for children 7.12 years where a different formula was used to estimate weight. For heights, the estimated values were significantly lower than the measured except for two year olds where both where almost similar. Scatter diagrams comparing actual and estimated plots showed linear relationship. Conclusion : The current methods of estimation are underestimating weights and heights of children in our environment. There is need for a multi-centre cohort study to test the various formulae in our children. Key words : Measured, Estimated, Weight, Height, Children.
Effect of Carboxyl Functionalized MWCNTs on the Cure Behavior of Epoxy Resin

Effects of carboxyl functionalized MWCNTs on the cure behavior of epoxy resin (EPIKOTETM resin 862 and EPICURETM curing agent W) were investigated by using differential scanning calorimeter in dynamic scan mode. Results indicated that nanotubes could initiate cure reaction at lower temperature while only 0.1 wt% samples were able to suppress the peak temperature (Tp) consistently regardless of different heating rate due to their higher reaction rate, other two batches (0.2 wt% and 0.3 wt% CNT) showed hardly any change in Tp compared to neat samples. Furthermore, addition of small amount (0.1 wt%) of CNTs significantly reduced the activation energy of the system but further addition elevated that due to their retarding effect. Also, a correlation was established between the dispersion state of CNTs in epoxy and total heat of reaction (ΔH) where lower ΔH was considered as an indication of better interfacial interaction of CNTs with matrix and hence, better dispersion. The difference in curing behavior of three different CNT percentages was discussed in terms of their steric hindrance and state of dispersion in the matrix.
The Views of Syrian Refugees Migrating to Turkey on the Turkish Language and Culture: Kilis Case.

This study aimed to determine the views of the Syrian refugees migrating to Kilis, Turkey on the Turkish language and culture, as well as the impact of this situation on their daily life. For that purpose, this study was done in accordance with a mixed design, using quantitative and qualitative research methods together. The target population of the quantitative study consisted of Syrian refugees between the ages of 18 and 25 who were living in Kilis. As a sample, the study was conducted with 309 participants who were chosen out of these refugees. In the qualitative part of the research, ten participants were selected out of those refugees. In the research, quantitative data were acquired through a survey prepared by the researcher, and qualitative data were obtained through face-to-face interviews and observations made in Kilis. Statistical methods and content analysis methods were employed in the data analysis. The research results have determined that Syrian refugees living in Kilis have generally positive views on the Turkish language and culture, they make an effort to learn them, and the cultural adaptation process is in progress for inclusion of the two communities.
Revisiting the Concept of Self-efficacy as a Language Learning Enhancer

Individuals’ self-efficacy beliefs determine the ways they perform in any domain, since they reflect the extent to which people feel capable to achieve certain accomplishments Bandura (1997). This paper describes how a group of intermediate school students’constant failure in the exams, demotivating attitudes, apathy and reluctance to learn English as a foreign language, relate with their perceived capability, self-perception and their prior experiences as language learners. This descriptive and exploratory case study was developed in a private language centre and involved 11 participants. The goal of the study was to understand the causes of the students’ demotivation and reluctance to the language. For this purpose, autobiographies become a springboard to examine students’ language learning experiences. This information was analysed based on the grounded theory approach proposed by Freeman(1998), and findings reveal that the inadequate teachers’ discourse, classroom environment, rapport and feedback strategies influenced students’ perceived capability to perform in the English class. In addition, the data showed that the supportive role of parents and relatives, encouraged learners to adopt a resilient attitude with respect to the difficulties while learning the language.
Revisiting Mutual Fund Performance Evaluation

Mutual fund manager excess performance should be measured relative to their self-reported benchmark rather than the return of a passive portfolio with the same risk characteristics. Ignoring the self-reported benchmark results in different measurement of stock selection and timing components of excess performance. We revisit baseline empirical evidence fund performance evaluation utilizing stock selection and timing measures that incorporate the self-reported benchmark. We introduce a new factor exposure based approach for measuring the – static and dynamic – timing capabilities of mutual fund managers. We overall conclude that current studies are likely to be misstating skill because they ignore the managers’ self-reported benchmark in the performance evaluation process.
