PORTUGUESE ADAPTATION OF STUDENTS ENGAGEMENT IN SCHOOLS INTERNATIONAL SCALE (SESIS)

Context: The importance of student’s engagement has been recently pointed out in research. However, there has been a lack of engagement assessment instrument, pertaining psychometric qualities. Objective: This paper presents the Portuguese adaptation of the “Student’s Engagement in School International Scale” (SESIS), drawn up from a12 countries international study (Lam et al., 2012; Lam et al., in press). Method: Psychometric properties of this scale were examined with data from 685 students from different grades (6 th , 7 th , 9 th and 10 th ), from both sexes, and different regions of the country. Results: Factorial analysis of the results, with varimax rotation, lead to three different factors which explain 50.88% of the variance. The scale integrates the original 33 items, and cognitive, affective and behavioural dimensions. For the external validity study, the relationship between student’s engagement in school results and other school variables — academic performance, self-concept — was considered, and significant relations were observed, as expected. Conclusion: The data presented highlights the qualities of SESIS, as well as its usefulness for research purposes. Suggestion: It is suggested the investigation of the extension of SESIS’s three-dimensionality, in future studiesKeywords: Innovation, technology, research projects, etc.
Investigation of the Mechanical Behavior of Facial Soft Tissues

The present thesis deals with the mechanical characterization of the highly non-linear, time-dependent, and isotropic behavior of facial soft tissues and their interaction within tissue structures. Theoretical and experimental approaches are combined to provide the basis for improved finite element (FE) modeling of complex facial tissue response, such as skin wrinkle formation in facial expressions and active muscle contraction in mastication. The theoretical work addresses the need for constitutive model equations capable of describing the active and passive behavior of individual tissues and their numerical implementation within the FE environment. The experimental investigations comprise the characterization of facial tissues at different length scales and include the visualization of interactions between soft tissue constituents. Experimental data are used for determination of mechanical tissue properties, i.e. for material parameter optimization and validation of numerically predicted tissue response. Finite element modeling of facial tissues considers the development of constitutive equations, their numerical implementation within the FE environment, and the generation of anatomy based model representations of soft tissue structures. The first part of the present work focuses on the numerical implementation of an elastic-viscoplastic material model particularly suitable for facial soft tissues and a skeletal muscle model representing the contractile properties of active tissues. In the case of the soft tissue model, a strongly objective integration scheme and a new mixed finite element formulation were developed based on the introduction of the relative deformation gradientthe deformation mapping between the last converged and current configurations. Numerical verification of the proposed integration scheme and the consistent linearization of the Hu-Washizu functional demonstrated mandatory objectivity under superposed rigid body motion and quadratic convergence, respectively. The numerical implementation of the skeletal muscle model based on the decoupled approachso the additive split of the strain energy function into a dilatational and a distortional partrevealed unphysical volume growth and negative eigenvalues of the tangent moduli. Consequently, a different functional form of the constitutive equations was proposed which avoids the additive split of the strain energy function and considers muscle as a nearly incompressible material, allowing for an adequate physical approximation of the mechanical response. Physically relevant simulations of facial tissues require the development of anatomy based FE models. Magnetic resonance imaging (MRI) measurements of the head of a 29 year old male provide the basis for the development of two FE modelsa multilayered
Spread of VIM-2 metallo-beta-lactamase in Pseudomonas aeruginosa and Acinetobacter baumannii clinical isolates from Ia ş i , Romania R ă spândirea metalo-beta-lactamazei VIM-2 printre izolate clinice de Pseudomonas aeruginosa ş i Acinetobacter baumannii din

Our study investigated the type of acquired metallo -βactamases (MBLs) produced by carbapenem-resistant clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii from five hospitals in Iasi, Romania and the genetic relatedness of the strains ca rrying MBL genes. Of 106 carbapenem-resistant strai ns, 50 were positive for MBL production after screening wi th Etest MBL. PCR analysis showed that 46 isolates (44 P. aeruginosa and 2 A. baumannii) carried a bla VIM gene. By DNA sequencing we identified two class 1 integrons carrying the blaVIM gene in the P. aeruginosa: IntI1-aacA7-bla VIM-2-qacE∆1 in 43 strains, and IntI1-aacA7∆blaVIM-∆cmlA1-qacE∆1 in one strain. In A. baumannii isolates the bla VIM-2 gene was not associated with a class 1 integron. Random amplified polymorphic DNA typing of VIM-2-producing P. aeruginosa strains revealed the presence of a major RAPD type in all five hospitals . Early detection and surveillance of such strains must be accompanied by rigorous infection control measures in order to limit the spread of MBLs in our clinical settings.
Relevant traits, genetic variation and breeding strategies in early silage maize

Variabilite genetique, criteres et strategies de selection des mais ensilage precoces. L'objectif de ce texte est presenter une reflexion autour des caracteristiques de valeur alimentaire et de valeur agronomique a prendre en consideration pour la selection de mais ensilage specifiques de cette utilisation, en prenant en compte la variabilite genetique disponible et les strategies de selection a employer. Un mais ensirage doit avoir un bon niveau de productivite, mais surtout une productivite stable au travers des differentes conditions de milieux. Sa teneur en grain doit se situer entre 46% and 50% selon la quantite et la qualite de l'amidon apporte par les complements de la ration. Sa precocite en plante entiere sera adaptee a la zone de culture envisagee, et un poids important sera donne a la tolerance au froid en debut et fin de vegetation, sans oublier la resistance aux champignons du sol exacerbant les degâts de froid. La resistance a la verse en vegetation du mais ensilage sera prise en compte a partir de qualites mecaniques des tiges, mais aussi a partir d'etude de la qualite de l'ancrage racinaire. L'amelioration du systeme racinaire devrait aussi conduire a des genotypes valorisant mieux les intrants et plus tolerants au deficit hydrique. En raison de la tres faible variabilite genetique pour la teneur en proteines, l'amelioration de la valeur azotee de ce fourrage devrait etre abordee au niveau de la variabilite de la degradabilite ruminale de ces proteines. La selection sur la valeur alimentaire comprendra une mesure de digestibilite de la plante entiere, avec l'utilisation d'une solubilite enzymatique predite en Nirs, une mesure digestibilite des parois estimee avec un critere de type IVDNSC (en francais Dinag), et a terme une prediction de l'ingestibilite. Les criteres de valeur alimentaire utilises devront etre valides par des essais avec des animaux. Pour eviter des risques de derive sur un caractere ou sur l'autre, la pression de selection pour la resistance a la verse sera simultanee a ces mesures de valeur alimentaire. Parce que les interactions genotypes x milieux pour la digestibilite sont faibles, les estimations pourront etre conduites dans un nombre limite d'environnements representatifs. Des progres en valeur alimentaire du mais ensilage viendront aussi de ceux realises dans la comprehension de la variabilite de composition monomerique de constitution des lignines et de celle des liaisons entre lignines et glucides parietaux. Les selectionneurs de mais ensilage devront aussi prendre en compte les contraintes environnementales et la necessite de pouvoir alimenter les troupeaux au plus faible cout. A ce titre, et puisque, dans un milieu donne, c'est la valeur du genotype qui conditionne pour l'eleveur la valeur de l'ensilage, pouvoir mettre sur le marche des hybrides ayant une genetique « mais ensilage » est une priorite pour les obtenteurs.
LARGE SHAREHOLDERS AND FIRM PERFORMANCE: EVIDENCE FROM TURKEY

Using data for the period 2003-2010 of 164 industrial firms listed on Istanbul Stock Exchange (BIST-Borsa Istanbul), we empirically explore the impact of large shareholders on firm performance measured by ROA and Tobin’s Q. Empirical findings based on panel data analysis suggest that large shareholders have a significantly positive effect on the performance of the firms. In other words, the concentration of corporate ownership overcomes conflict of interest between the small shareholders and the managers. At the same time, in the case when share ownership of the large shareholder exceeds a certain level, once again, we find significant positive relation between large shareholders and firm performance. As a result, while we do not reject the validity of the efficient monitoring hypothesis, but rather the expropriating hypothesis in Turkey.
Influence of fibre properties in air jet spinning

Introduction Whilst the technology behind air jet spinning can be traced back at least 30 years\ the commercial exploitation of the technique for short staple spinning must be regarded as a relatively recent development. Several manufacturers have developed systems for producing air jet yarns but the MJS (Murata Jet Spinning) system is by far the most successful. Mor~ recently, the use of air jet technology has been applied to the production of two-assembly wound yams3 which are subsequently twisted to yield a two-fold yarn . Fasciated yarn4 is a term applied to a staple fibre yam which is composed of a central core of essentially parallel fibres bound together by wrapper fibres . The technique which is used to create such structures is often referred to as 'twist transference' and relies on the use of a false twisting process, where 'edge fibres' (which are at the outside edges of the drafted strand and are not false twisted) form wrapper fibres as the core of the yam untwists. Jet spinning is a method for producing fasciated yarns, the essential feature of which being the use of air jets as the false twisting between the MJS system (Fig.2) and its predecessor is that the newer system utilizes two twisting jets which operate in contrarotation. This arrangement has been shown 5 , both theoretically and practically, to produce a larger number and better distribution of wrapper fibres which result in a stronger yarn. Several reports6 9 have been published on the comparison of properties of jet-spun yarns with those of ringand rotor-spun yarns. Investigations have also been carried out into the effect of processing conditions on yarn properties I 0, II and, to a lesser extent, the role of fibre properties has also been analyzed 12 , 13. The general finding of most of these researchers is that whilst relatively strong yarns can be produced from polyester and polyester-rich blends, with other fibre types the yarn tenacity is significantly lower than that of ring-spun equivalent. The results reported in this paper represent a part of an ongoi ng research programme concerned wi th the theoretical and practical aspects of jet spinning I4 18 •
On the irrationality of polynomial Cantor series

N=1 P (N) ∏N n=1Q(n) with polynomials P (x), Q(x) ∈ Q[x] such that Q(n) ∈ Z for all n ∈ Z and not with rational functions Q(x). In 1869 Cantor [3] proved a first irrationality result for sums of the form ∑∞ N=1(bN/ ∏N n=1 an) where {an}n=1 and {bn}n=1 are sequences of positive integers with an ≥ 2 for all n. His result was generalised in various ways by Oppenheim [10] in 1954 and their results are the basis of the results in the present paper; see Theorem 2.1. Extensions of Oppenheim’s results were given by Erdős and Strauss [4], [5], Hančl [6], Hančl and Tijdeman [7]–[9],
Element uptake, accumulation, and resorption in leaves of mangrove species with different mechanisms of salt regulation

Abstract. Element uptake from substrate and resorption capacity of nutrients before leaf shedding are frequently species-specific and difficult to determine in natural settings. We sampled populations of Rhizophora mangle (salt-excluding species) and Laguncularia racemosa (salt-secreting species) in a coastal lagoon in the upper section of the Maracaibo strait in western Venezuela to estimate accumulation and resorption of mineral elements. Leaves collected fortnightly during 4~months within the rainy season were stratified as young, adult, old, and senescent. We measured changes in concentration of essential elements (N, P, S, K, Mg, Ca, Mn, Fe) and Na (elemental analyzer and plasma spectrometer), leaf succulence (water/area), and specific leaf area (area/mass) and calculated relative resorption or accumulation of elements in senescent leaves before abscission. Succulence was similar in young leaves of both species and increased with age, more abruptly in L. racemosa. Concentrations of N, K, and Mg were higher in R. mangle, whereas those of P, Na, Ca, and S were higher in L. racemosa. Concentration of K per unit leaf water decreased with age in both species; however, Na concentration in R. mangle remained at a similar level until increasing markedly in senescent leaves, whereas in L. racemosa it increased throughout the leaf lifespan. Relative changes based on leaf mass, leaf area, or whole leaf did not differ statistically. On a leaf mass basis both species showed resorption of C, N, P, and K and accumulation of S, Na, Mg, Ca, Mn, and Fe. However, R. mangle was more efficient restricting Na and S uptake, resorbing P, and accumulating Fe than L. racemosa. The P / N resorption ratio is > 1 in R. mangle and
Project Management Certification and Experience: The Impact on the Triple Constraint

Successful project management is primarily measured by the project manager’s ability to meet the classic triple constraint. What impact does certification and experience have on meeting project scope, time, and cost goals? This research study examines these factors by eliciting data from practicing project managers, with and without certification, and with various years of experience.
MANAGEMENT OF VASCULAR WILT OF LENTIL THROUGH AQUEOUS PLANT EXTRACTS IN TARAI REGION OF UTTARAKHAND STATE

Lentil wilt caused by Fusarium oxysporum Schechet. Emend. Snyder and Hansen f. sp. lentis Vasudeva and Srinivasan is an important disease and it is a limiting factor to lentil production. The present work aimed at evaluating the antifungal activity of some plant extracts in vitro and in vivo condition. Field experiments were conducted at N. E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. Field trials were carried out consecutively during Rabi 2010-11 and 2011-12 crop seasons in Randomized Block Design (RBD) with three replications, using ‘Pant L-639’ a released cultivar to wilt. The plot size was 3.0×1.5m 2 with row spacing of 30cm. On the basis of in vitro studies, effective plant extracts were used for seed treatment. Effect of selected plant extracts on disease incidence, 1000 grain weight and yield of lentil was recorded. All the botanicals were observed effective. However, garlic extract seed treatment followed by ginger, showed lowest disease incidence, highest grain yield as well as maximum 1000-grains weight in comparison to check plot. The reduction in the pathogen population/ growth, decreased disease incidence and increased grain yield indicates that these extracts could have important roles in biologically based management strategies for control of Fusarium wilt disease under organic mode of lentil cultivation.
Managerial Overconfidence and Share Repurchases

Following prior studies, we use keywords in press portrayals to gauge managerial overconfidence. We hypothesize that managerial overconfidence is related to a manager's perception that the firm is undervalued. Results from 2744 share repurchase programs launched by 783 listed firms in Taiwan confirm this hypothesis. We find that managerial overconfidence is positively correlated with the intensity of share repurchasing, which is measured by scale, execution, frequency, and the difference between the announced price and post‐execution price. Moreover, the programs launched by overconfident managers were not undervalued and therefore were associated with reduced post‐announcement returns.
FREQUENCY OF POLY CYSTIC OVARY SYNDROME IN PATIENTS WITH PREMENOPAUSAL BREAST CANCER

Background: Polycystic ovary syndrome (PCOS) is a heterogeneous complex genetic disorder characterized by hyperandrogenemia hyperinsulinemia insulin resistance and chronic anovulation. It is the most common endocrine disorder in women of reproductive age with an enigmatic pathophysiologic and molecular basis. Obesity hyperandrogenism and infertility occur frequently in PCOS which mostly have a genetic predisposition and are features known to be associated with the development of breast cancer risk. Objective: In present study frequency of PCOS in patients with premenopausal breast cancer was compared with the frequency in women without breast cancer. Materials and Methods: This is a case-control study which compared PCOS frequency in 166 patients with premenopausal breast cancer and 166 healthy controls with normal mammography in last 6 months. Results: Eleven patients (6.62%) in case group and 16 patients (9.63%) in control group had polycystic ovary syndrome according to their questionnaire. The difference was not significant (p=0.645). Conclusion: There was no relationship between frequency of polycystic ovary syndrome and breast cancer in this study. This might be due to the age of patients with breast cancer in this study which was mostly over 40. It could be significant if the patients were chosen in lower age for showing more effect of genetic than environment. The adjustment or matching of other risk factors could help to find the better results.
Classifying Space for Proper Actions and K-Theory of Group C*-algebras

We announce a reformulation of the conjecture in [8,9,10]. The advantage of the new version is that it is simpler and applies more generally than the earlier statement. A key point is to use the universal example for proper actions introduced in [10]. There, the universal example seemed somewhat peripheral to the main issue. Here, however, it will play a central role.
REDUCTION OF ENDOSULFAN RESIDUES IN BRINJAL FRUITS DURING PROCESSING

Laboratory experiments were carried out to find out the dissipation and to assess the effect of household processing like washing, boiling and washing plus boiling on reduction of endosulfan residues on brinjal (Solanum melongena L.) at room temperature and refrigerated conditions. Half life periods were 3.30 and 3.41 days at room temperature and 3.81 and 3.72 days at refrigerated conditions for single and double dose, respectively, showing faster dissipation at room temperature. The processing results indicated that washing plus boiling led to more than 72 per cent loss of endosulfan residues. Washing, boiling as well as washing plus boiling were found comparatively more effective in samples kept at room temperature than under refrigerated conditions.
What Does Realized Volatility Tell Us About Macroeconomic Fluctuations

This paper provides an extensive analysis of the predictive ability to economic activity of several measures of asset realized volatility. We construct monthly measures of aggregated stock market and industry-level stock volatility, and bond market volatility from daily returns. We model log realized volatility as composed of a long-run component that is common across all these series, and a short-run sectoral component. If volatility indeed has components, volatility proxies are characterized by large measurement error, which veils analysis of their fundamental information and relationship with the economy. We find that realized volatility of asset returns helps predict future economic activity. Notably, there are substantial gains from using the long term component of the volatility measures for linearly projecting future economic activity, as well as for forecasting business cycle turning points. We extend the analysis to extract a nonlinear long-run component of the volatility series and evaluate its performance in an out-of-sample real time analysis. Given the unexpected severity of the recent 2007-2009 recession, this period offers an ideal environment to evaluate ex-ante predictive performance. The nonlinear volatility component yields early real time signals of the upcoming recession, concomitant with the first signs of distress in the financial markets due to problems in the housing sector in mid 2007. In addition, the model implied chronology is consistent with the recession timeline and periods of financial distress during the subsequent period.
The macroeconomic determinants of remittances in Bangladesh

This paper examines the macroeconomic determinants of workers’ remittances in Bangladesh. Various regressions in the paper find that the macroeconomic variables such as inflation, interest rate, exchange rate of Bangladesh and GDP of the five remittance sending countries have significant impact on remittance. In the analysis it is found that if the domestic interest rate goes up by 1%, on average, then the remittance will increase by 1.94%. Therefore, remittance in Bangladesh is very responsive to changes in the domestic interest rate. Again, if the GDP of the rest of the five countries increases by 1%, then remittance will increase by 3.06 %
Haematological evaluation of Cryptolepis sanguinolenta stem ethanolic extract in rats

Background : The use of Cryptolepis sanguinolenta extract in medicare has gained attention since its discovery. Aim : This study sought to evaluate the haematological effect of ethanolic extract of Cryptolepis sanguinolenta stem in rat model. Materials and Methods : Control rats received 0.5ml of distilled water. Treated rats were administered oral doses of the extract at different concentrations (50, 150, and 250mg/kg body weight). All rats were maintained on a control diet. Treatment lasted for 21 days. Results : Red blood cells and haematological parameters were comparable in all groups. Similarly, total white blood cells, neutrophils and lymphocytes counts were not ignificantly altered except in rats treated with 250mg/kg/bw of the extract. However, administration of the extract led to a dose-dependent rise in platelet counts. Conclusion : This study showed that C. sanguinolenta stem ethanolic extract presents haematological challenges on white blood cells and platelets. It showed localized systemic toxicity by selectively stimulating the bone marrow. Keywords : Cryptolepis sanguinolenta , red blood cell, white blood cell, platelet, toxicity
