CONCEPTUALIZING RELATIONSHIP TEACHERS INTERNAL SUPERVISION, MOTIVATIONAL BELIEFS, AND STUDENT'S SELF-REGULATED LEARNING

The present study examined the correlations of scores for motivational beliefs and self-regulated learning outcomes among 257 undergraduate students business program in Indonesia who responded to Motivational Strategies for Learning Questionnaire. Analysis showed a positive correlation between scores for motivational beliefs and self-regulated learning outcomes but a negative one for scores on test anxiety and self-regulated learning. This study also examines the effect of internal mentoring teachers to motivational beliefs and self-regulated learning. The result of this study indicated that student self-regulated learning related to career development dimension and role modeling in the internal mentoring or teaching supervision and self-efficacy and intrinsic values in motivational beliefs. In addition, self-regulated learning is more influenced by the self-efficacy and intrinsic values rather than internal mentoring supervisors or teachers. Test anxiety does not affect self-regulated learning, but negative associated significantly with self-efficacy. Various discussions on the matter presented in this study.
Balance sheet effects and the choice of exchange rate regime in developing countries

We investigate the choice of regime amongst hard pegs, soft pegs, managed floats and independent floats for a panel of developing countries. There is evidence of a matched ordering of regimes and country characteristics. We find some evidence for the ‘balance sheet' hypothesis that foreign liabilities in the banking system and foreign debt are associated with less exchange rate flexibility, particularly when a ‘de facto’ regime classification is used. Easily the best predictor of a country's current regime is its regime in the previous year.
The demand for international reserves in the Eurosystem. Implications of the changeover to the third stage of EMU.

In this paper we analyse the implications of the euro for the international reserves in the Eurosystem. Two conceptually different effects of the changeover have to be distinguished: a technical effect that largely arises as a matter of accounting, and a behavioural effect that stems from the fact that the optimal demand of the aggregate Eurosystem is not equal to the sum of the optimal country levels. The technical effect arises from two main sources: the abolishment of the ECU-creating mechanism, and the redefinition of international reserves which precludes (former) reserves that were denominated in euro-currencies. As a result the average reserves of the Eurosystem in 1999 amounted to $287 billion, considerably less than in 1998 ($345 billion). We then derive a reserve demand function for the aggregate Eurosystem using panel data estimation techniques and simulate reserve demand for the situation after the regime shift. The optimal aggregate level of reserves turns out to be some $188 billion, which implies excess reserves in the Eurosystem amounting to approximately $100 billion in the year 1999. We go on by proposing a key by which this excess could be allocated to the individual countries taking the asymmetric distribution of reserves in the Eurosystem into account. Finally we classify and enumerate the proposals for making use of the estimated reserve overhang. (author's abstract)
Robust Portfolio Selection by Bayesian Estimation Methods

This research proposes several performance-based measures to evaluate the estimation of a high-dimensional covariance matrix, where the number of variables can be close to the number of observations. In case of high-dimensional data, the sample covariance contains a lot of estimation error, and is not even invertible in some cases. This research makes a comparative analysis of covariance estimation based on dierent priors for the Bayesian estimation methodology. The performances of the resulting portfolios are judged in the realistic capital asset environment of the New York Stock Exchange. The sample covariance points out to be an unt estimator in case of high-dimensional data. When a proper prior is chosen for the Bayesian estimation method, this method does not suer from this dimensionality issue and clearly outperforms the natural estimator.
A Sinkhorn-Newton method for entropic optimal transport

We consider the entropic regularization of discretized optimal transport and propose to solve its optimality conditions via a logarithmic Newton iteration. We show a quadratic convergence rate and validate numerically that the method compares favorably with the more commonly used Sinkhorn--Knopp algorithm for small regularization strength. We further investigate numerically the robustness of the proposed method with respect to parameters such as the mesh size of the discretization.
Innovative Applications of Ultrafine-Grained Materials

This chapter focuses on multifunctional properties of ultrafine-grained (UFG) metallic materials processed by severe plastic deformation (SPD), such as enhanced mechanical properties, excellent superplasticity, and wear resistance. Based on these multifunctional properties, the potential innovative application for UFG materials processed by SPD is introduced in the next section, including innovative application in micro-forming, nano- implants, electro-connections, and sport engineering.
Investigating the Impact of Lean Management on Innovation in Vietnamese SMEs

Internationalization in society and economy has fostered promptly the production volumes and product diversification due to the complexity in customers’ design. Lean management has been known as effective and efficient tools in the management of customer value by reducing cost of the resources necessary to achieve the needs of customers. Today innovation has been considered as driving force of business success in every industry in the context of high competition. The link between lean management and innovation capability has been recently proposed in some literatures, which show that some aspects of lean management may negatively affect and some may positively affect a company’s capability to be successful with certain types of innovations. This paper develops a framework to analyze the impact of lean management on innovation capability in Vietnamese small and medium enterprises. Five propositions has been presented and tested in the sample of 122 SMEs engaged in lean management. The findings suggest that due to implementation of lean management the changes of organizational structure and inter-departmental coordination have positive effect and the changes of human resources management and organizational culture have negative effect on the innovation capability.
A Hydrodynamical Mechanism for Generating Astrophysical Jets

Whenever in a classical accretion disk the thin disk approximation fails interior to a certain radius, a transition from Keplerian to radial infalling trajectories should occur. We show that this transition is actually expected to occur interior to a certain critical radius, provided surface density profiles are steeper than �(R) / R −1/2 , and further, that it probably corresponds to the observationally inferred phenomena of thick hot walls internally limiting the extent of many stellar accretion disks. Infalling trajectories will lead to the convergent focusing and concentration of matter towards the very central regions, most of which will simply be swallowed by the central object. We show through a perturbative hydrodynamical analysis, that this will naturally develop a well collimated pair of polar jets. A first analytic treatment of the problem described is given, proving the feasibility of purely hydrodynamical mechanisms for astrophysical jet generation.
Mining HCI Data for Theory of Mind Induction

Human-computer interaction (HCI) results in enormous amounts of data-bearing potentials for understanding a human user’s intentions, goals, and desires. Knowing what users want and need is a key to intelligent system assistance. The theory of mind concept known from studies in animal behavior is adopted and adapted for expressive user modeling. Theories of mind are hypothetical user models representing, to some extent, a human user’s thoughts. A theory of mind may even reveal tacit knowledge. In this way, user modeling becomes knowledge discovery going beyond the human’s knowledge and covering domain-specific insights. Theories of mind are induced by mining HCI data. Data mining turns out to be inductive modeling. Intelligent assistant systems inductively modeling a human user’s intentions, goals, and the like, as well as domain knowledge are, by nature, learning systems. To cope with the risk of getting it wrong, learning systems are equipped with the skill of reflection.
Avalanche Forecast Verification Through a Comparison of Local Nowcasts with Regional Forecast

This paper presents a methodology and a new dataset used by the Canadian Avalanche Center's Yukon Field Team in the winters of 2013 and 2014 to validate their forecasts of avalanche dan- ger and primary avalanche problem. Using established techniques 77 local nowcasts were compared to operational and public regional forecasts over a variety of lead times. Preliminary results indicate that these forecasts accurately predicated observed conditions for 69% to 85% of cases. There was little dif- ference in accuracy found between the forecasts of danger and avalanche problem and the length of forecasts lead times did not have a significant affect. Several sources of bias are identified that should be filtered in future studies and suggestions for new research are presented.
RISK MANAGEMENT IN PUBLIC-PRIVATE PARTNERSHIP ROAD PROJECTS USING THE REAL OPTIONS THEORY

Application of public-private partnership (PPP) agr eements as a method for implementation of transport infrastructure projects is a common practice in man y countries. Although history of this type of agree ments includes examples of failures and successes, in som e cases outcomes were responsibility of one partner , while in others outcomes were, either favorable or not, shared between partners. Considering long term obligations between contract parties, which are for highway projects usually 25 to 30 years, and compl ex nature of this type of projects with number of risk s, there is a need for contractual flexibility whic h will provide a right for a change in investment decision depending on the project’s future performance. Application of real options theory in road PPP proj ects enables this kind of flexibility and share of associated risks. Overview of theory of real options and examp les used in road PPP projects is part of this paper which objective is to develop a valuation model to determ ine the value of a buyback option in the case of unexpected outcome, i.e. in the case of excessive r evenues. This option provides contractual flexibili ty for the public sector, that is the right to buyback the project from the private sector for the predetermi ned price.

Abstract The relationship between school culture and academic achievement was tested through meta- analysis in this paper. 54 studies of which only 25 can be included to the meta- analysis were examined in literature review. Through this paper, sample group of 20287 people was formed by gathering 25 independent studies. Based on the findings of analysis which were made by using random effects model, there were no publication bias in the obtained data and it was confirmed that school culture had a statistically significant effect on students’ academic achievement.
Artistic Value

cases one can see how the outcome in terms of values and ends is affected by one's view of the nature of the subject. I t is obvious that our view of the nature of religion will be affected by our view of the how and the whether of divine existence. I t is equally true that our notion of the worth of mathematics must be affected by our view of what it is that is the object of mathematical study, whether it is a creation of our own or a voyage of discovery, whether its substance is mere marks or inscriptions, or Platonic forms, or the form of the world known in experience, or the consequences of arbitrarily defined concepts. All our enterprises will be profoundly affected depending on our knowledge or ignorance of the kinds of assertions we are dealing with and what procedures of verification are appropriate to them. Similarly our notion not only of the being of art but also of the creator and the participant in the aesthetic process must affect our notion of what values are to be gained, what it is that can be learned or inculcated in art. The philosopher's own interest in art and artists is the best reason why the artist, particularly the teacher, should have a reciprocal interest in the philosophy of art. Artistic Value
Mitochondrial DNA evidences reflect an incipient population structure in Atlantic goliath grouper ( Epinephelus itajara , Epinephelidae) in Brazil

The Atlantic goliath grouper is a critically endangered species that inhabits estuarine and reef environments and is threatened primarily by fishing activities and habitat destruction. Despite the urgent need for protection, its genetic conservation status remains unknown. The aim of the present study was to evaluate the gene flow among the populations of the species along the coast of Brazil based on the control region of the mitochondrial DNA. The results indicate low haplotype diversity (0.40-0.86) and very low nucleotide diversity (0.1-0.5%). They also show that the genetic diversity of the species varies considerably along the coast and that this finding may be especially important for the identification of priority areas for its conservation. The population analyses indicate a low but significant degree of genetic structuring (Φ ST =0.111), probably due to the occurrence of rare haplotypes at some locations, although the genetic differentiation between sites was not correlated with geographic distance (r=0.0501; p=0.7719), and the shared haplotypes indicate that gene flow occurs among all locations along the Brazilian coast. The results of the pairwise FST indicate a high degree of genetic differentiation between locations. The incipient population structuring detected in the present study is not related systematically to the geological or physical features of the Brazilian coast. The complex interaction of fluctuations in sea level, marine currents, and the reproductive characteristics of the species hampers the identification of the specific role of each of these processes in the gene flow dynamics of the population units of the Atlantic goliath grouper. The low overall levels of genetic diversity, the pairwise FST values and the significant population structuring among groups (Φ CT ) identified in the present study all reinforce the critically endangered status of the species and are inconsistent with the presence of a single, panmictic population of groupers on the Brazilian coast. The results of this study suggest that, though it may be incipient, the observed genetic structuring must be taken into account in order to prevent potential problems, such as outbreeding depression, in the management of wild stocks.
Cytotoxicity of Alpinia galanga Rhizome Crude Extract on NIH-3T3 Cells

BACKGROUND : Alpinia galanga ( A. galanga ) was reported as a potential medicinal source due to its wide effect. A. galanga rhizome crude extract (ARCE) was reported to have high cytotoxic effect in cancer cells, but low in normal cells. However half maximal inhibitory concentration (IC 50 ) of ARCE is not clearly known yet. Hence, current study was conducted to investigate the IC50 of ARCE in normal standard fibroblast cell line, NIH-3T3 cells. METHODS : Rhizomes of A. galanga were collected, peeled, dried, milled and weighed. Extraction was performed using maceration method, then filtered and evaporated. ARCE with various concentrations were applied in NIH-3T3 cells for 24 or 48 hours. Cells were documented and counted with 3-(4,5-dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide (MTT) assay. RESULTS : Five hundreds grams of simplicia were macerated with ethanol and evaporated, 1 mg/mL crude extract with total volume of 114 mL was obtained. By addition of ARCE in NIH-3T3 cell culture, number of NIH-3T3 cells were shown less when treated with higher concentration of ARCE. Cell numbers of 0, 3.125, 6.25, 12.5, 25 and 50% ARCE treatment for 24 hours are 11,531, 11,352, 10,920, 10,365, 9,471, 8,360, respectively, meanwhile for 48 hours are 13,219, 12,686, 12,278, 11,390, 10,279, 8,390, respectively. CONCLUSION : IC 50 of ARCE in 24 hours treatment was 620.5 mg/mL, while in 48 hours treatment was 666.6 mg/mL. Hence, ARCE is suggested to have low cytotoxic effect in NIH-3T3 cells. KEYWORDS : Alpinia galanga , ginger, extract, cytotoxic, MTT, NIH-3T3
Testing a leadership model among managers in a corporate environment

Orientation: Leadership is a multifaceted phenomenon, which has been researched in depth, together with emotional intelligence as an industrial psychology concept. There is, however, one issue not mentioned and sufficient studies to show that this is the extent to which authentic leadership could have a mediating effect on emotional intelligence and psychological wellbeing of managers within South Africa. Research purpose: The main purpose of this research is to test whether authentic leadership is a mediator between emotional intelligence and the well-being among managers within the South African context. Motivation for the study: Investigating the effect of leadership on emotional intelligence and psychological well-being of managers in the workplace, could provide new insights on the way that managers are managed in the organisational context. Additionally, as a study on the effect of leadership on emotional intelligence and psychological well-being is a newly researched concept in the South African context, the information could be of value for organisations. Research design, approach and method: A quantitative research design was used in this cross-sectional study. A purposive sampling procedure of employees from low to middle management level were drawn from various corporate companies in South Africa (N = 249). The main focus was on the low to middle level managers, who made up the bulk of the sample. Measuring instruments used in the study were the Authentic Leadership Questionnaire (ALQ), Mental Health Continuum Scale (MHCS) and the Greek Emotional Intelligence Scale (GEIS). The MPLUS program was utilised to test the mediation effect of authentic leadership on emotional intelligence and psychological well-being. Main findings: A positive relationship between authentic leadership and its antecedent and outcome was found. More specifically, authentic leadership mediated (small effect) the relationship between emotional intelligence and psychological well-being. Practical/Managerial implications: Managers in the corporate environment in South Africa should be aware of the effect of their level of emotional intelligence on their leadership styles. Additionally, the managers should be conscious of what effect emotional intelligence and the leadership style that they adopt could have on their overall psychological well-being.
Eigenvalue Ratio Test for the Number of Factors

This paper proposes two new estimators for determining the number of factors (r) in static approximate factor models. We exploit the well-known fact that the r largest eigenvalues of the variance matrix of N response variables grow unboundedly as N increases, while the other eigenvalues remain bounded. The new estimators are obtained simply by maximizing the ratio of two adjacent eigenvalues. Our simulation results provide promising evidence for the two estimators.
Analysis of Research in Adoption of Person-Centred Healthcare Systems: The Case of Online Personal Health Record

Although the personal health record (PHR) has enormous potential to ameliorate both documentation of health-related information and care of individuals, it has not been adopted as originally expected. The purpose of this paper is to analyse research studies in PHR adoption and provide a comprehensive taxonomy of the factors affecting PHR adoption. We searched three categories of key terms across nine academic databases and identified an initial set of 7,468 research studies. We filtered papers on the basis of their title, abstract and full text (91 remaining papers) to have relevant PHR adoption research studies. Based on the conceptualisation of adoption factors in the 91 included papers, a list of factors that impacted on PHR adoption was identified and we categorised them into six main clusters. This review is a good starting point for researchers who are interested in adoption of PHR systems. Furthermore, it provides valuable information for healthcare practitioners and PHR system developers.
Microevolution of Mitochondrial Cytochrome oxidase subunit I in Drosophila melanogaster at ＂Evolution Canyon＂, Israel

We determined the sequence of mitochondrial Cytochrome oxidase subunit I (CO1) in two Drosophila melanogaster strains originating at “Evolution Canyon”, Israel. CO1 nucleotide sequences from two iso-female strains, 2-1 and 6-1, were 1,534 and 1,543 base-pairs, respectively. In each strain, ATAA was used in initiation of translation. Exchange rates for nucleotide and amino acid sequences were larger in the 6-1 strain than in the 2-1 strain when Oregon-R was used as the standard. Non-synonymous exchange rate was larger than synonymous exchange rate among the three strains.

It takes as input sentences in the source language which is in English and outputs a translation of the sentences in the target language which is in Khasi.
Pore Size Distribution Analysis of Coal-Based Activated Carbons: Investigating the Effects of Activating Agent and Chemical Ratio

The present study attempts to investigate the effects of different chemical agents and chemical ratios on pore structure of coal-based activated carbons. The adsorption isotherm data of two series of activated carbons prepared from bituminous coal by chemical activation with potassium hydroxide and zinc chloride were used. Four well-known models of Dubinin-Stoeckli, Stoeckli, Horvath-Kawazoe, and improved Horvath-Kawazoe were applied for the characterization of these porous solids. Although the results showed some differences among the models that arise from their fundamental assumptions, in general they are found to be comparable. Results showed that samples activated by ZnCl2 provide higher-adsorption capacity than those from KOH. In each series, it was shown that the pore volume increases with increasing impregnation ratio, ranging from 50% to 200%. Activated carbons obtained at low chemical ratio in ZnCl2 series (up to 100%) showed microporous structure, while those with higher ratios became predominantly mesoporous. In the KOH series, increasing KOH created more micropores in the carbon structure in the whole range of studied chemical ratio.
