Rad se bavi rezultatima ispitivanja djece školskih obveznika, a koje provodi školski pedagog, i njihovih uspjeha na kraju prvog razreda. Na teroijskoj razini govori se o pojmu zrelosti i spremnosti ...djeteta za polazak u prvi razred. Cilj je bio utvrditi jesu li rezultati Upitnika za procjenu zrelosti za prvi razred povezani sa školskim uspjehom, posebice matematičko predznanje s uspjehom u Matematici i govorno-jezični razvoj s uspjehom u Hrvatskom jeziku te ukupni bodovi upitnika s općim školskim uspjehom na kraju prvog razreda. Istraživanje je provedeno na uzorku od 60 učenika koji su 2016./2017. školske godine završili prvi razred, a s kojima je 2015./2016. školske godine obavljena
procjena zrelosti za upis u prvi razred. Podaci su se prikupili analizom pedagoške dokumentacije odnosno uvidom u razrednu knjigu (imenik) učenika prvog razreda te uvidom u Upitnike za procjenu zrelosti
za upis u prvi razred. Dobiveni rezultati ukazuju na povezanost spremnosti djeteta kod provođenja ispitivanja školske pedagoginje i njihova uspjeha na kraju školske godine. Rezultati Upitnika važni su kako bi se učitelji i stručna služba upoznali s razvojnim razlikama među
učenicima, sposobnostima i predznanjem djece te kako bi se učenici mogli ravnomjerno podijeliti u razredne odjele.
The paper explains the results of the examination of school children, which are carried out by the school counselor, in relation to their success at the end of the first grade. It studies their maturity and readiness to start going to the first class. The goal of this research is to determine if the results of The questionnaire for first grade maturity assessment are connected with school success, especially regarding the connection of prior mathematical knowledge with later mathematical success and the connection of verbal language development with success in Croatian language, as well as total points od the questionnaire with grade results report at the end of the first grade. The research is conducted on the sample of 60 students who finished first grade in 2015/2016 school year, and who passed The questionnaire for first grade maturity assesment in 2015/2016 school year. The data was collected through pedagogical documentation analysis, i.e. through examination of the first grade book (school register) and through The questionnaire for first grade maturity assessment. The results claim that there is a correlation between the child's readiness during the school counselor's assessment protocol and their success at the end of the school year. The results of The questionnaire are important for the school counselor in order to be able to divide the students into classes
evenly and to inform the teachers and their advisory services of the development differences between students, their abilities and prior knowledge.
Die Arbeit befasst sich mit den Befragungsergebnissen bei schulpflichtigen Kindern, die der Schulpädagoge durchführt, und ihrem Erfolg am Ende der ersten Klasse. Es wurde geprüft, was man unter der Reife und Bereitschaft des Kindes für den Start in die erste Klasse betrachtet. Das Ziel war es festzustellen, ob die Ergebnisse des Fragebogens für die Schulreife-Einschätzung der ersten Klasse mit dem Schulerfolg zusammenhängen, insbesondere mathematische Vorkenntnisse mit
dem Erfolg in Mathematik und Sprachentwicklung mit dem Erfolg in der kroatischen Sprache sowie die Gesamtpunkte des Fragebogens mit Allgemeinschulerfolg am Ende der ersten Klasse. Die Prüfung wurde an einer Stichprobe von 60 Schülern durchgeführt, die 2016/2017 die erste Klasse beendeten und mit denen 2015/2016 die Schulreife-Einschätzung für
die Einschreibung in die erste Klasse erledigt wurde. Die Angaben wurden durch Analyse der pädagogischen Dokumentation, beziehungsweise durch die Klassenbucheinsicht der Schüler erster Klasse und durch die Einsicht des Fragebogens zur Reifeeinschätzung für die Einschreibung in die erste Klasse erhoben. Die erzielten Ergebnisse deuten auf den Zusammenhang zwischen der Bereitschaft der Kinder bei der Prüfungsdurchführung der Schulpädagogin und ihrer Erfolge am Schuljahresende. Die Ergebnisse des Fragebogens sind wichtig, um die Schüler gleichmäßig in Klassen einordnen zu können und damit sich die Lehrer und Fachkräfte mit den Entwicklungsunterschieden, Fähigkeiten und
Vorkenntnissen der Schüler vertraut machen.
The Permian-Triassic time interval was a period of high sedimentation rates in the intracontinental Karoo rift basin of northwestern Mozambique, reflecting high exhumation rates in the surrounding ...high ground Precambrian-Cambrian basement and juxtaposed nappes. U-Pb LA-MC-ICPMS dating and Lu-Hf isotopic analysis of detrital zircons from the Late Permian-Early Triassic Matinde Formation of the Karoo Supergroup is used as a reliable proxy to map denudation patterns of source regions. Data allow discrimination of U-Pb age populations of ca. 1250-900 Ma, a secondary population between ca. 900-700 and a major contribution of ages around ca. 700-490 Ma. Zircon grains of the Mesoproterozoic age population present Mesoproterozoic (1000–1500 Ma) to Paleoproterozoic (1800–2300 Ma) Hf TDM ages, with positive (0 to +11) and negative εHf values (−3 to −15), respectively. The younger U-Pb age population also presents two different groups of zircon grains according to Lu-Hf isotopes. The first group comprise Paleoproterozoic (1800–2300 Ma) ages, with highly negative εHf values, between −10 and −22, and the second group exhibits Mesoproterozoic ages (1200–1500 Ma), with increased juvenile εHf values (ca. 0 to −5). These Hf isotopes reinforce the presence of unexposed ancient crust in this region. The oldest U-Pb age population resembles the late stages of Grenville Orogeny and the Rodinia Supercontinent geotectonic activity mostly represented by magmatic rocks, which are widely present in the basement of northern Mozambique. The juvenile Hf-isotope signature with an older age component is associated to rocks generated from subduction processes with crust assimilation by continental arcs, which we correlate to rocks of the Nampula Complex, south and east of the Moatize-Minjova Basin. The U-Pb ages between 900 and 700 Ma were correlated to the calc-alkaline magmatism registered in the Guro Suite, related to the breakup phase of Rodinia, and mark the western limit of the Moatize-Minjova rift basin together with the Mungari Nappe and Chacocoma Granite, also probable sources. The εHf-isotopic signature (ca. −23 to 0) with Meso- and Paleoproterozoic Hf model ages of these zircons suggest assimilation of older crust by the Guro Suite continental arc. The Late Neoproterozoic - Cambrian U-Pb ages (ca. 700-490 Ma) comprise the wide interval of high-grade metamorphism, klippen and plutonism related to the Pan-African Orogeny. Hf-isotope pattern indicate high remelting of the older Mesoproterozoic and Paleoproterozoic crust. These ages correspond to magmatic and granulite metamorphic ages of the Monapo and Mugeba klippen, Nampula Complex and Guro Suite/Mungari Nappe/Chacocoma Granite rocks. The data suggests that these units were main source areas for the sediments of the Matinde Formation. The main Cambrian ages are related to the late stages of Pan-African Orogeny, marked by crustal delamination in NE Mozambique that was responsible for an extensive crustal partial melting associated to high-grade granulitic metamorphism and generation of large granitic plutons. The Nampula Complex was probably a large geotectonic entity in the Late Mesoproterozoic and reworked during the Pan-African Orogeny. This evidence, added to the N-NW paleoflow of the Proto-Zambezi river and provenance data, suggests that the Nampula Complex, Guro Suite and its juxtaposed nappes formed a high ground source area for fluvial sediments that fills the Moatize-Minjova Basin. Permian-Triassic rifting in northern Mozambique was induced by far-field stresses transferred from Gondwana margins. This stress disrupted the Nampula Complex reactivating Precambrian structures and fabrics, while the Jurassic-Cretaceous breakup of Gondwana and latter landscape evolution led to its actual morphology and configuration.
•Detrital zircon dating provides U-Pb Mesoproterozoic to Cambrian provenance.•Hf-isotope data suggests a mantle and crustal origin for the zircons analyzed.•U-Pb and Hf-isotopes indicate a south and eastwards provenance.•Guro Suite, Nampula Complex and juxtaposed klippen were the main sources.•Headwaters of Permian-Triassic fluvial systems were at the East Africa Orogen.
Patients with diabetes and obesity are at increased risk of developing disturbances in intestinal function. In this study, we characterized jejunal function in the clinically relevant ...leptin-deficient ob/ob mouse, a model of diabetes and obesity. We measured transepithelial short circuit current (Isc), across freshly isolated segments of jejunum from 12-week-old ob/ob and lean C57BL/6J (female and male) mice. The basal Isc was significantly decreased (~30%) in the ob/ob mice (66.5±5.7 μA/cm(2) n=20) (P< 0.05) compared with their lean counterparts (95.1±9.1 μA/cm(2) n=19). Inhibition with clotrimazole (100 μM, applied bilaterally) was significantly reduced in the ob/ob mice (-7.92%±3.67% n=15) (P<0.05) compared with the lean mice (10.44%±7.92% n=15), indicating a decreased contribution of Ca(2+)-activated K(+) (KCa) channels in the ob/ob mice. Inhibition with ouabain (100 μM, applied serosally) was significantly reduced in the ob/ob mice (1.40%±3.61%, n=13) (P< 0.05) versus the lean mice (18.93%±3.76% n=18), suggesting a potential defect in the Na(+)/K(+)-adenosine triphosphate (ATP)ase pump with leptin-deficiency. Expression of cystic fibrosis transmembrane conductance regulatory protein (CFTR) (normalized to glyceraldehyde-3-phosphate dehydrogenase GAPDH) was significantly decreased ~twofold (P<0.05) in the ob/ob mice compared with the leans, whilst crypt depth was unchanged. Villi length was significantly increased by ~25% (P<0.05) in the ob/ob mice compared with the leans and was associated with an increase in Villin and GLUT5 expression. GLUT2 and SGLT-1 expression were both unchanged. Our data suggests that reduced basal jejunal Isc in ob/ob mice is likely a consequence of reduced CFTR expression and decreased activity of the basolateral KCa channel and Na(+)/K(+)-ATPase. Understanding intestinal dysfunctions in ob/ob jejunum may allow for the development of novel drug targets to treat obesity and diabetes.
