Factors Mediating the Effect of Gender on Ninth-Grade Turkish Students' Misconceptions Concerning Electric Circuits.

This study was designed to identify and analyze possible factors that mediate the effect of gender on ninth-grade Turkish students' misconceptions concerning electric circuits. A Simple Electric Circuit Concept Test (SECCT), including items with both practical and theoretical contexts, and an Interest- Experience Questionnaire about Electricity (IEQ) were administered to 1,678 ninth-grade students (764 male, 914 female) after the completion of a unit on electricity to assess students' misconceptions and interests-experiences about electricity. Results of the concept test indicated that general performances of the students were relatively low and that many students had misconceptions in interpreting electric circuits. When the data were analyzed using MANOVA and follow-up ANOVAs, a gender difference for males was observed on the dependent variable of total scores on the 10 practical items; however, there was no signi- ficant gender difference on the dependent variable of total scores on the six theoretical items. Moreover, when the same data were analyzed using MANCOVA and follow-up ANCOVAs, controlling students' age and interest-experience related to electricity, the observed gender difference was mediated on the total scores on the practical items. 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 603-616, 2004 There is a consensus in the literature noting that differences between sexes initiate at birth and proceed through childhood (Bem, 1981; Eccles, Adler, & Meece, 1984; Linn & Hyde, 1989). Historically, two explanations have been suggested to account for the girls' lower performance in achievement: the biological explanation and the sociological explanation. First, gender imbalance was thought to be the result of different brain structures; however, explanations based on gender- specific socialization had displaced the brain difference model. While much of the earlier debate in the 1970s focused on the roles played by biological and sociological factors (Maccoby & Jacklin, 1973; Sherman, 1978), most of the recent research has been directed towards identifying sociocultural factors that contribute to the observed gender differences. Bem (1981), Eccles et al. (1984), and Linn and Hyde (1989) all proposed that early differences between boys and girls in science become magnified by cultural influences from society and school. Related literature has shown that males outperform females (Erickson & Erickson, 1984; Greenfield, 1997; Johnson,
Implementation of Machine Learning Techniques to PredictPost-Collegiate Earnings & Student-Loan Repayment Prospects

In this age of self education and personalized unconventional learning, majority of people still see a college degree as a gateway to job the workforce and to enter their field of interest and this outlook does not seem to be disappearing. However, the burden of rising college tuition and increasing student-loan default rates raises concerns. A common belief that only prestigious, elite and expensive institutions can bring about attractive work life, is being debunked. There exists many institutions that do not belong the ivy league and does not have huge tuitions, but, their graduates end up quite successful. Due to the lack of relevant portals and resources that provide such data, it would make more sense to introduce such a practices in the market. This research paper presents a possible solution to this gap, by filling it with a prediction model that takes data from College Scorecard (US Department of education, US Census Bureau, etc) and provides estimation of possible future earning and their chances with student-loan debt repayment. The research makes use of multiple regression, Random Forest, XGBoost and Artificial Neural Networks to achieve this goal.
Reducing Unwarranted Disparities: The Challenge of Managing Knowledge Sharing between Judges

In their role as decision-makers, judges face the challenge of the law failing to provide clear answers to concrete cases. This may result in dissimilar decisions and outcomes in similar cases. In order to reduce unwarranted disparities, judges should participate in knowledge exchanges on a regular basis. That way, they can benefit from each other's expertise, insights and experiences and make better informed decisions. In order to manage this process in the court more effectively, a better understanding of the knowledge sharing behavior of judges is required. In this article, we will discuss how four dimensions (the technological, managerial, social and motivational dimension) can influence the knowledge sharing behavior of judges. Based on this discussion, a research model is proposed.
Genetics of yellow mosaic virus (YMV) resistance in cultivated soybean [Glycine max (L.) Merr.]

In the present study, 100 soybean germplasm were screened for three years (2009-2011) in New Delhi, a hot-spot for YMV disease in order to identify resistant sources. A set of 29 genotypes, mostly improved varieties of Northern India were identified with higher level of resistance consistently over the years. The inheritance of YMV resistance studied in F1 and F2 populations of three crosses involving two highly resistant varieties DS9712 and DS9814 and two highly susceptible genotypes JS335 and PI542044 indicated that the resistance is dominant and is controlled by single major gene. The chi-square test showed complete fitness to 3 resistant: 1 susceptible ratio in all the three F2 populations viz., PI542044 x DS9712, PI542044 x DS9814 and JS335 x DS9712. The findings of the study will pave the way for mapping the gene for YMV resistance with linked molecular marker. The segregating populations generated will act as starting materials for developing improved lines with YMV resistance.
Application of the Double-Tangent Construction Of Coexisting Phases to Any Type of Phase Equilibrium For Binary Systems Modeled With the Gamma-Phi Approach

The double–tangent construction of coexisting phases is an elegant approach to visualize all the multiphase binary systems that satisfy the equality of chemical potentials and to select the stable state. In this paper, we show how to perform the double-tangent construction of coexisting phases for binary systems modeled with the gamma-phi approach. By introducing the molar Gibbs energy change on mixing (gm), the mathematical equations to handle are simple and can easily be used by the students during exercise classes. Keywords: phase equilibria, properties change on mixing, double–tangent construction of coexisting phases, Gibbs energy.
Assessment of completeness and legibility of prescriptions received at community pharmacies

Introduction: A prescription is a written order put into practice by a health-care practitioner such as physician, dentist, hakim, vaidya, veterinarian in the form of instructions that govern the plan of care/treatment for every individual patient. Prescription errors account for elevated number of medication errors that could potentially result in unwanted effects. These are considered as most preventable and on the other hand common cause of iatrogenic injuries and increased health care cost. Thus, it is essential to know the fact on completeness and legibility of prescriptions. Objectives: This study was intended to assess the legibility and completeness of prescriptions which are received at pharmacist attended community pharmacies settings of rural India. Materials and Methods: It is a prospective, cross-sectional research work performed among community pharmacies sited in Anantapur, Andhra Pradesh, India. Put together, 285 prescriptions were acknowledged during the study episode, from different hospitals and clinics with different specialty physicians. The completeness of prescriptions was analyzed by means of a checklist of vital dimensions in parallel to the World Health Organization guidelines for medication order writing. The legibility was assessed based on the scoring system on quality of prescription. Results: This study results show that all the prescriptions were hand written. The legibility was lacking in almost half of the prescriptions analyzed. We also found that prescriptions are less concentrated on patients′ information and medication information than physicians′ information. Conclusion: It is necessary to critically address and evaluate the completeness and legibility of the prescriptions in a continuous and frequent manner. Further, this is the time to change it into the computerized electronic prescribing from handwritten prescription to reduce the medication errors.
International Review of Research in Open and Distributed Learning Properties of Teacher Networks in Twitter: Are They Related to Community-Based Peer Production?

their activity within the community, especially related with peer production. We analyzed the topology of these networks in two ways: a) the indirect relations by counting followers and followed people; and b) the conversational networks by counting mentions in tweets. We also analyzed the communities’ websites in order to elucidate whether their production was lightweight or heavyweight peer production. Results indicate that teacher networks adopt a community clusters archetype in which some teachers act as bridges between several groups. Although these networks do not form a tight crowd, their degree of tightness is superior to that of the general networks established in Twitter. Our results also indicate that the degree of tightness is important for sustaining heavyweight peer production and strong leadership can play a crucial role in establishing long-term commitment to a collective task.

Study of the Allelopathic Potential of Extracts of Azadirachta Indica (Neem)

The allelopathic potential of extracts of Azadirachta indica L. , which is one of the most dominant weeds in tropical regions of South-west Asia, was investigated under laboratory conditions. The n-hexane-soluble, acetone-soluble and water-soluble fractions obtained from the acetone extract of A. indica shoots inhibited the germination and the growth of roots and shoots of six test plant species. The inhibitory activity of the water-soluble fraction was greatest, followed by that of the n-hexanesoluble and acetone-soluble fractions in all bioassays. Significant reductions in the germination and growth of the roots and hypocotyls were observed as the extract concentration increased. The concentration-dependent responses of the test plants to the fractions suggested that all three fractions might contain allelochemicals, but that the greatest potential was in the water-soluble fraction. These results indicate that A. indica may produce potent allelochemicals, which should be investigated further in the laboratory and the field.
Flora and vegetation of greenstone formations of the Yilgarn Craton: south-west Ravensthorpe Greenstone Belt

A quadrat-based survey of the flora of the south-west region of the Ravensthorpe Greenstone Belt identified 321 taxa, including six taxa of conservation significance and three weed species. All of the conservation-listed taxa were known to the area. Range extensions were recorded for three taxa and additional collections of two Austrostipa species currently under taxonomic description were made. Six community types were derived from statistical classification of the 50 quadrats. These community types were similar to those described from other parts of the Ravensthorpe Greenstone Belt. As with the other greenstone belts of the Yilgarn Craton, soil chemical parameters and site physical characteristics were influential in delineating community types. Only a small portion of the study area is in the conservation estate; mining and exploration pressures remain the primary threat to this species-rich area.
Blame No One ?Investment Decisions of the Polish Stock-Listed Companies

It is often raised that enterprises in transition countries are cursed with credit constraints and insufficient capital. Regardless of whether this belief holds for the whole of the economy, the Agency Theory provides a useful both theoretical and empirical framework helping to verify the efficiency of investment decisions in case of companies for which ’objective’ future cash-flow valuation is available. The assertion of managerial discretion has been verified empirically for many different countries with the analytical background provided by user cost of capital and Tobin’s Q theories. This paper’s contribution is the analysis of the Polish stock-listed companies behavior with the particular attention devoted to the corporate governance issues. We find that on average these companies overinvest relative to their opportunities, while this phenomenon is more severe in the case of even partial state ownership.

Board of Directors and Tobin’s Q: Evidence from U.K.Firms

This study investigates whether board of director characteristics have an impact on corporate performance. Recent studies highlight that findings that such characteristics do have an impact may be affected by endogeneity issues in the data, which could lead to biased results. This study responds to this concern by using a generalised method of moments regression model) developed by WintoDYki et al. (2011). Data for the analysis are extracted from BoardEx, FAME, and Datastream databases for the period 1999 – 2009. The final sample includes a total of 634 UK firms listed in the London Stock Exchange. The results suggest that board structure is partly determined by past corporate performance. Considering this, the results document that there is no relation between characteristics of the board of directors and corporate performance measured by Tobin’s Q. This is inconsistent with much prier empirical studies and policy recommendations on corporate governance that suggests that corporate governance mechanisms develop corporate performance. In addition, this result indicates that the findings of the earlier corporate governance studies that do not take into account the dynamic nature of corporate governance may be affected by bias.
Carbon dioxide and methane annual emissions from two boreal reservoirs and nearby lakes in Quebec, Canada

Abstract. The results of dissolved GHG (CO 2 and CH 4 ) measurement campaigns carried out in Quebec (Canada) during the open-water periods and under-ice in a newly created reservoir (Eastmain 1), a 25 year old reservoir (Robert-Bourassa) and in three reference lakes are presented. While CO 2 partial pressures varied with season with a net increase under the ice cover, CH 4 partial pressures did not. We were able to extrapolate the highest CO 2 partial pressures reached in the different studied systems just before ice break-up with high spring emission period. We then estimated the springtime CO 2 fluxes and compared them to annual CO 2 fluxes and GHG fluxes. Thus we clearly demonstrated that in our systems CH 4 fluxes was of minor importance in the GHG emissions, CO 2 fluxes representing around 90% of the annual fluxes. We also pointed out the importance of springtime emissions in the annual budget.
Anticlastogenic effect of Allium sativum extract against lead-induced necrosisin liver and kidney of albino rats

The anticlastogenic potential of Allium sativum aqueous extract was evaluated on lead-induced necrosis in liver and kidney tissues of albino rats in vivo. The rats were administered 2.5mg/kg lead acetate and 100mg/kg Allium sativum aqueous extract for a period of 4-weeks. The change in organ to body weight ratio of the treated rats as well as the pathological condition of the liver and kidney tissues were also assessed. The result showed that change in organ to body weight ratio of the animals fed with lead acetate was significant (P<0.05) when compared with control. Besides, the histopathological examination of liver and kidney tissues of rat fed with the clastogen alone indicates grossly necrotic or mutated cells, riddled with lesions of varying degrees. However, a slight modification was observed in tissues of animals fed with the extract which were fairly normal and well vascularized. Hence, Allium sativum could possibly offer protection against heavy metal-induced necrosis in liver and kidney tissues.
Relaxation of dark matter halos: how to match observational data?

We show that moderate energy relaxation in the formation of dark matter halos invariably leads to profiles that match those observed in the central regions of galaxies. The density profile of the central region is universal and insensitive to either the seed perturbation shape or the details of the relaxation process. The profile has a central core; the multiplication of the central density by the core radius is almost independent of the halo mass, in accordance with observations. In the core area the density distribution behaves as an Einasto profile with low index (n ∼ 0.5); it has an extensive region with ρ ∝ r −2 at larger distances. This is exactly the shape that observations suggest for the central region of galaxies. On the other hand, this shape does not fit the galaxy cluster profiles. A possible explanation of this fact is that the relaxation is violent in the case of galaxy clusters; however, it is not violent enough when galaxies or smaller dark matter structures are considered. We discuss the reasons for this.
Huhe, Narisong and Tang, Min (2017) Institutionalizing from the middle : understanding provincial legislation and grassroots democracy in China. Studies in Comparative International Development. ISSN 1936-

Nominal democratic institutions under non-democratic regimes vary across countries. This study intends to advance our understanding of such nominal democratic institutions by exploring the role of one aspect of the regime, government hierarchy. Focusing on the village-level democratization in China, we stress the intermediary role of the provincial-level governments in shaping the variant outcomes of grassroots democracy across the country. Through an analysis of a national sample, we find that divergent provincial legislative interpretation of central policies is a key determinant of the access to power and democratic governance of village-level governments. Our finding suggests that authoritarian states can employ various institutions to gather more accurate information, accommodate local variations, contain potential intra-government disagreement and thus maintain regime stability.
ASSESSMENT OF EXPOSURE TO AIR POLLUTION FROM ROAD TRAFFIC : USE OF AIR DISPERSION MODEL CALINE 4 AT A FINE SCALE IN CRACOW PRACE GEOGRAFICZNE , zeszyt 127

This article deals with the road traffic air pollution modeling which is also part of a main multidisciplinary study of health risk characterization untitled: “Air pollution generated by road traffic and childhood asthma in Cracow”. Cracow, a city declared as a UNESCO World Heritage Site, constitutes a relevant urban area to study insofar road traffic as a strong anthropogenic source of air pollution. The final aim of the health study is to establish in Cracow the relationship between air quality and the development of asthma among children. We have chosen the air dispersion model CALINE4 and its software interface, CALROADS VIEW, to estimate the PM 10 and NO 2 concentrations generated by road traffic at 43 key intersections in Cracow during the period 2001-2005. This model is recognized as an international reference in road traffic air pollution modeling. The concentration of traffic and trips in the historical downtown area and the importance of exchanges between the two downtowns of Cracow (historical downtown and Nowa Huta) are the main causes of high air pollution levels from road traffic. Depending on the pollutant considered (PM 10 , NO 2 ) as well as the density of traffic and the meteorological situations, areas of exposure to air pollution and their potential health effects to the exposed population are quite different in time and in space. The main results show that: 1) Only the NO 2 exposure areas reach the residential areas because the PM 10 areas of exposure (Avg: 66.8 m SD: ± 48.5, max: 284 m) are quite less extensive than those of NO 2 (Avg: 125.4 SD: ± 64.4, max: 381 m); 2) Extension of these two pollutant areas is proportionally related to the density of traffic and is extended in an unsymmetrical way around roads depending on meteorological cases determined by both the Pasquill-Gifford classification and the wind directions. According to our methodology, the validation of estimated PM 10 and NO 2 concentrations shows that they have been overwhelmingly validated.
Bioaccumulation and Ecological Risk Assessment of Heavy Metals in the Soil and Wild Rats in Riyadh, Saudi Arabia

The present study aimed to analyze the impact of environmental contamination on metal accumulation and oxidative stress in wild rats, Rattus rattus, collected from metal-polluted areas in the vicinity of Riyadh Region, Saudi Arabia.Soil samples and wild rats were collected from four locations (Dhurma, Kharj Road, Al Muzahmiyah and Laban Valley ) that differ in their extent of pollution load. However, Laban Valley was taken as a reference site in this study . High concentrations of heavy metals (cadmium, lead and zinc) were recorded in soil and tissues ( liver, kidney and hair) of animals collected from Dhurma , the site with high anthropogenic pressure. Moreover, a significant increase in the level of liver malondialdeyhde (MDA) coupled with an inhibition of the activity of superoxide dismutase (SOD), catalase (CAT), Glutathione Peroxidase(GPx), Glutathione Reductase (GR) and Glutathione-S-Transferase (GST) were recorded in Dhurma followed by Kharj Road and Al Muzahmiyah compared to the reference site.From these results , it could be concluded that that the selected biomarkers are useful for the assessment of pollution impacts in natural environments and the small wild animal R. rattus can be used as a bioindicator model for metal toxicity in an arid environment.
