Teachers’ Perceptions of Financial Literacy and the Implications for Professional Learning

Consumer, economic and financial literacy education at school is central to active and informed citizenship. Over the past decade, the Australian Securities and Investments Commission has led various policy initiatives and influenced curriculum and resource development in this area. However, there remains a paucity of research exploring how Australian teachers make sense of and approach their work as financial literacy educators or their professional learning needs and interests in this interdisciplinary field. This article reports research exploring practising teachers’ perceptions of the opportunities for financial literacy teaching and learning. Data were collected from 35 teachers in 16 Victorian primary schools. The findings suggest a need to educate teachers to: reflect upon the knowledge, skills and capabilities required to make informed financial decisions; identify and interpret the possibilities for financial literacy teaching and learning in the Australian Curriculum; and enact sophisticated pedagogical practice

Status febrilis mit Bewusstlosigkeit

Zusammenfassung: Eine zerebrale Beteiligung bei Malaria mit Plasmodium vivax ist ungewöhnlich. Diese schwere Form der Malaria ist üblicherweise durch Plasmodium falciparum bedingt. Wir berichten über eine 18-jährige Patientin aus Pakistan mit langjähriger intermittierender Fieberanamnese, welche 4Monate nach Einreise in die Schweiz erstmals an einer zerebralen Vivax-Malaria erkrankt. Die eindrückliche neurologische Symptomatik mit Amaurosis und Bewusstseinsstörung bildete sich in diesem Fall unter Therapie in wenigen Tagen zurück. Jedoch sind Todesfälle bei zerebraler Malaria durch Plasmodium vivax beschriebe

35-jährige Patientin mit generalisiertem Krampfanfall und nicht-kardiogenem Lungenödem nach Intoxikation

Zusammenfassung: Nach Intoxikation mit Verapamil-Retardpräparaten sind verzögerte und prolongierte kardiovaskuläre Nebenwirkungen bekannt. Wir berichten über 2 seltene Nebenwirkungen in Form eines generalisierten Krampfanfalls und eines nicht-kardiogenen Lungenödems, welche erst 13 bzw. 48h nach der Intoxikation aufgetreten sind. Aufgrund der verzögert auftretenden und prolongierten Arzneimittelwirkungen muss bei Intoxikationen mit retardierten Kalziumantagonisten die gastrointestinale Dekontamination mit antegrader Darmspülung und anschließender Aktivkohletherapie auch bei initial symptomfreien Patienten bis mindestens 24h nach Intoxikation gefordert werde

Lymphogranuloma venereum: Eine alte Krankheit in neuem Kleid

Zusammenfassung: Lymphogranuloma venereum ist eine sexuell übertragene Erkrankung verursacht durch Chlamydia trachomatis der Serotypen L1, L2 und L3. Die klassische Manifestation ist eine schmerzhafte inguinale Lymphadenopathie, welche ohne Behandlung zu schwerwiegenden Komplikationen führt. Daneben wird seit einigen Jahren gehäuft eine ulzerierende Proktitis beschrieben, speziell bei Männern, die Sex mit Männern haben. Da die klinischen Beschwerden unspezifisch sind, muss bei Proktitis aktiv nach Chlamydia trachomatis gesucht werden. Die Diagnostik des Lymphogranuloma venereum erfolgt heute hauptsächlich mit molekularen Testverfahren. Zur Therapie wird Tetracyclin über 3Wochen empfohlen. Die Erkrankung wird anhand von 5 aktuellen klinischen Fallbeispielen dargestell

Membrane-assisted enzymatic production of galactosyl-oligosaccharides from lactose in a continuous process

Functional foods such as oligosaccharides have attained significant acceptance in Japan and are attracting interest elsewhere. Beneficial physiological properties are attributed to oligosaccharides. Here, we describe the continuous production of oligosaccharides from a low-cost substrate (lactose) in a continuous membrane-assisted reactor (both polymeric and inorganic membranes were tested). Different enzymes, a number of feed concentrations, and different average residence times were investigated. The enzymes were used in their native form. Retention and recycling of the enzyme was successful, while the products together with some unreacted substrate and byproducts were removed as the ultrafiltration permeate. For the ultrafiltration, a steady-state flux of about 20 l/m2 hr was achieved. A maximum oligosaccharide concentration of over 40 %w/w was reached with an average residence time of 1 hr and a feed lactose concentration of 31 %w/w. Pilot scale experiments based on the laboratory tests are also reported

Infrared spectroscopy of phytochrome and model pigments

Fourier-transform infrared difference spectra between the red-absorbing and far-red-absorbing forms of oat phytochrome have been measured in H2O and 2H2O. The difference spectra are compared with infrared spectra of model compounds, i.e. the (5Z,10Z,15Z)- and (5Z,10Z,15E)-isomers of 2,3,7,8,12,13,17,18-octaethyl-bilindion (Et8-bilindion), 2,3-dihydro-2,3,7,8,12,13,17,18-octaethyl-bilindion (H2Et8-bilindion), and protonated H2Et8-bilindion in various solvents. The spectra of the model compounds show that only for the protonated forms can clear differences between the two isomers be detected. Since considerable differences are present between the spectra of Et8-bilindion and H2Et8-bilindion, it is concluded that only the latter compound can serve as a model system of phytochrome. The 2H2O effect on the difference spectrum of phytochrome supports the view that the chromophore in red-absorbing phytochrome is protonated and suggests, in addition, that it is also protonated in far-red-absorbing phytochrome. The spectra show that protonated carboxyl groups are influenced. The small amplitudes in the difference spectra exclude major changes of protein secondary structure

SVA retrotransposon insertion-associated deletion represents a novel mutational mechanism underlying large genomic copy number changes with non-recurrent breakpoints

Background: Genomic disorders are caused by copy number changes that may exhibit recurrent breakpoints processed by nonallelic homologous recombination. However, region-specific disease-associated copy number changes have also been observed which exhibit non-recurrent breakpoints. The mechanisms underlying these non-recurrent copy number changes have not yet been fully elucidated. Results: We analyze large NF1 deletions with non-recurrent breakpoints as a model to investigate the full spectrum of causative mechanisms, and observe that they are mediated by various DNA double strand break repair mechanisms, as well as aberrant replication. Further, two of the 17 NF1 deletions with non-recurrent breakpoints, identified in unrelated patients, occur in association with the concomitant insertion of SINE/variable number of tandem repeats/Alu (SVA) retrotransposons at the deletion breakpoints. The respective breakpoints are refractory to analysis by standard breakpoint-spanning PCRs and are only identified by means of optimized PCR protocols designed to amplify across GC-rich sequences. The SVA elements are integrated within SUZ12P intron 8 in both patients, and were mediated by target-primed reverse transcription of SVA mRNA intermediates derived from retrotranspositionally active source elements. Both SVA insertions occurred during early postzygotic development and are uniquely associated with large deletions of 1 Mb and 867 kb, respectively, at the insertion sites. Conclusions: Since active SVA elements are abundant in the human genome and the retrotranspositional activity of many SVA source elements is high, SVA insertion-associated large genomic deletions encompassing many hundreds of kilobases could constitute a novel and as yet under-appreciated mechanism underlying large-scale copy number changes in the human genome

Evolutionary Breakpoints in the Gibbon Suggest Association between Cytosine Methylation and Karyotype Evolution

Gibbon species have accumulated an unusually high number of chromosomal changes since diverging from the common hominoid ancestor 15–18 million years ago. The cause of this increased rate of chromosomal rearrangements is not known, nor is it known if genome architecture has a role. To address this question, we analyzed sequences spanning 57 breaks of synteny between northern white-cheeked gibbons (Nomascus l. leucogenys) and humans. We find that the breakpoint regions are enriched in segmental duplications and repeats, with Alu elements being the most abundant. Alus located near the gibbon breakpoints (<150 bp) have a higher CpG content than other Alus. Bisulphite allelic sequencing reveals that these gibbon Alus have a lower average density of methylated cytosine that their human orthologues. The finding of higher CpG content and lower average CpG methylation suggests that the gibbon Alu elements are epigenetically distinct from their human orthologues. The association between undermethylation and chromosomal rearrangement in gibbons suggests a correlation between epigenetic state and structural genome variation in evolution
