title: Australian classroom teacher homework practices in designing homework learning resources
Creators: name: Richardson, Susan
Publisher: name: IARTEM e-journal
Year: 2014

description: There has been considerable research into the design and development of teaching and learning resources for classroom instruction. However, far less research emphasis exists concerning the design and development of learning resources for homework and out-of-school learning. In Australia the approach tends to be a classroom-up approach to the design, development and implementation of learning resources. In this approach, the classroom teachers’ role is of critical importance in designing, developing and implementing learning resources that support homework. In this respect, Horsley and Walker (2012) have found that a relationship exists between classroom teachers’ homework practices and the teaching and learning resource base of these practices. This paper presents preliminary results from a research investigation concern-ing the approach taken by two primary classroom teachers in the design, development and use of homework teaching and learning resources. The research explored teacher perspectives on homework practices using focus groups, and examined actual teacher homework practices using a stimulated recall method.

description: In this paper, we present a map describing the main geomorphological features of the coastal and marine area between the towns of Albenga and Savona (Ligurian Sea, NW Mediterranean) corresponding to a coastal stretch of ∼40 km. To produce this map, we collated data from the literature, orthophotos, perspective photos, multibeam and side scan sonar data, and undertook direct surveys to ground truth data obtained using indirect techniques. We divided the information into nine thematic layers, including bathymetry, natural coastal types, geomorphological elements, seafloor coverage (both geological and biological), coastal and nearshore dynamics, human influence on coastal and marine environments, coastal occupation and protected areas.

description: The aggregation of amyloid-β (Aβ) remains the most acceptable pathological hallmark of Alzheimer’s disease (AD). In search for natural products exhibiting anti-amyloidogenic effects, phytochemical analyses were conducted on Uncaria lanosa f. philippinensis leading to the purification of oxindole alkaloid uncarine E (isopteropodine) (1), the phenylethanoid tyrosol (2), the megastigmane vomifoliol (3), and the previously reported alkaloids mitraphylline and isomitraphylline. This is the first report of compounds 1–3 in the title plant, and tyrosol (2) from the genus Uncaria. Assessment of the anti-amyloidogenic potential using Thioflavin T assay showed 91% (at 50 µM) and 70% (at 25 µM) inhibitions for compound 1. Tyrosol (2) gave 76% (at 50 µM) and 63% (at 25 µM) inhibitions. These compounds may be further tested to elucidate their mechanism in the prevention of Aβ aggregation. To the best of our knowledge, this is the first report on the anti-amyloid aggregation activity of compounds 1 and 2.

description: Solving the indefinite Helmholtz equation is not only crucial for the understanding of many physical phenomena but also represents an outstandingly-difficult benchmark problem for the successful application of numerical methods. Here we introduce a new approach for evolving efficient preconditioned iterative solvers for Helmholtz problems with multi-objective grammar-guided genetic programming. Our approach is based on a novel context-free grammar, which enables the construction of multigrid preconditioners that employ a tailored sequence of operations on each discretization level. To find solvers that generalize well over the given domain, we propose a custom method of successive problem difficulty adaption, in which we evaluate a preconditioner's efficiency on increasingly ill-conditioned problem instances. We demonstrate our approach's effectiveness by evolving multigrid-based preconditioners for a two-dimensional indefinite Helmholtz problem that outperform several human-designed methods for different wavenumbers up to systems of linear equations with more than a million unknowns.

description: The better knowledge of crack driving forces is very important in the assessment of the reliability of timber structures. This work is part of the CLIMBOIS project related to the effects of climatic and mechanical variations on the durability of timber structures. It deals with several fracture tests performed in climatic chamber on the cracking of specimens machined in Douglas and White Fir species. Opening mode crack growth is studied with adapted specimen’s geometry. Both static and creep tests are performed, in variable humidity environment, with specific experimental set ups. The evolutions crack lengths are posted versus time. Experimental results obtained offer better understanding of the fracture behavior under variable environment of the studied species.

description: The model pathogen Parastagonospora nodorum is a necrotroph and the causal agent of the wheat disease Septoria nodorum blotch (SNB). The sequenced P. nodorum genome has revealed that the fungus harbours a large number of secondary metabolite genes. Secondary metabolites are known to play important roles in the virulence of plant pathogens, but limited knowledge is available about the SM repertoire of this wheat pathogen. Here, we review the secondary metabolites that have been isolated from P. nodorum and related species of the same genus and provide an in-depth genome-wide overview of the secondary metabolite gene clusters encoded in the P. nodorum genome. The secondary metabolite gene survey reveals that P. nodorum is capable of producing a diverse range of small molecules and exciting prospects exist for discovery of novel virulence factors and bioactive molecules.

description: Hemp concrete is a multifunctional ecological material used in buildings which is obtained by mixing together a binder and hemp particles (the non-fibrous fraction of the hemp stem called “shiv” or “hurd”). Due to its high porosity (ranging from 60 to 90% in volume), it presents an “atypical” mechanical behavior and its hygrothermal and acoustical properties are particularly interesting. This paper focuses on the impact of the water content of hemp concretes on their acoustical and thermal properties. Four mixtures of hemp concrete were manufactured using a binder and two shives under two distinct stresses of compaction. It is shown that water content does not affect significantly the acoustical properties of hemp concretes altough a swelling effect can be detected by an increase of resistivity and a decrease of porosity and viscous characteristic length. Finally, thermal conductivity rises almost linearly with water content while evolutions of thermal diffusivity and specific heat capacity are different depending on the concrete.

description: The starch-hemp is a bio-composite materials and it consisted of starch binder and hemp shives. This bio-composite material is a new durable material for construction and building. In this work, the study on mechanical and acoustical behavior of the starch-hemp bio-composite materials was carried out. The starch-hemp bio-composite materials specimens with three Hemp/Starch ratios (H/S=6, 8 and 10), were manufactured by using the optimal binder and the hemp shives mixtures (0-5 mm+0-15 mm and 0-5 mm+0-20 mm). Influence of the H/S ratio and hemp shives size on density, ultimate compressive stress, tensile strength, elasticity modulus and Poisson's ratio of the starch-hemp bio-composite materials was studied and analyzed. The study on acoustical behavior shows that the starch-hemp bio-composite materials are a very good sound absorber material for medium and high frequencies with a value around 0.7. The influence of the H/S ratio on the absorption coefficient is small. The results show that the starch-hemp biocomposite materials have a good mechanical and acoustical performance and can be used as building materials.

description: We isolated two phytoconstituents using bioassay guided isolation for anti-diabetic property from the hydroalcoholic extract of Lindernia ciliata (Colsm.) Pennell (Family: Linderniaceae). We assessed the anti-diabetic potential using various assays, including the glucose absorption assay, glucose uptake in isolated rat abdominal muscle assay, insulin secretion by RIN-5F cells assay, α-amylase inhibition activity, and DPP-4 inhibition assay. The results from our study indicated that the ethanol and water fractions obtained from the hydroalcoholic extract significantly improved glucose uptake, demonstrating promising anti-diabetic properties. Further investigation led to the isolation of two distinct compounds, LCF-1 (IUPAC name: 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one) (LCF-1) and LCF-2 (IUPAC name: 3S,10R,13R,17R)-17-[(2R,5R)-5-ethyl-6-methylheptan-2-yl]-10,13-dimethyl-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-ol). Consequently, our findings suggest that LCF-1 and LCF-2 are two phytoconstituent derived from the hydroalcoholic extract of L. ciliata, could serve as a potential source of anti-diabetic agents. This highlights its suitability for further development in the creation of herbal pharmaceuticals for diabetes treatment.

description: Here we present the results of a study analysing the contents addressed by the activities included in textbooks for the subject of “environmental studies”. In the interest of delving deeper into methodologies and techniques that an inclusive school can promote, and after an exhaustive national (Spanish) and international bibliographical review, we have found evidence of the importance of cooperative learning among students as a strategy for facilitating the acquisition of inclusive values. Moreover, the subject of environmental studies expressly aims to address the acquisition of knowledge regarding our community's cultural, linguistic and historical values. Our findings question that these aims are actually achieved. In addition, we present a description of the competencies, aims, contents and activities included in several school textbooks.

description: A key part of structural damage monitoring occurring in timber materials aims to identify the most relevant descriptors of critical damage mechanisms. The sudden release of stored energy during the damage process, known as the Acoustic Emission (AE), is a very suitable technique for in situ health monitoring applications. Various signal processing and pattern recognition techniques have been performed for damage feature extraction from AE signals. The purpose of this paper is to use the Hilbert–Huang transform (HHT), for relating a specific damage mechanism to its acoustic signature. The applicability of this local instantaneous frequency descriptor for damage characterization in timber materials is discussed. First, the HHT is used to identify the damage signature, by correlating the measured AE signals with known acoustic sources. Then, the performance of the Hilbert–Huang transform damage classification approach is evaluated.

description: In a general context of global warming, an increasing interest is observed on the use of biobased insulating materials. Indeed, this kind of materials ensures good thermal characteristics while drastically reducing fossil energy consumption and greenhouse gas emissions associated with their manufacture. In addition, thanks to their permeancy (ability to allow diffusion of water vapor within their porous network), these materials present an alternative option to isolate and rehabilitate buildings made with non-industrial materials (rammed earth, cob, adobe,...) and whose stability requires to maintain a water exchange with the outside. Bio-based materials from plants have promising thermal and acoustical characteristics which are the subject of several studies now. In this work, the acoustical properties of hemp particles (shiv), flax (shiv), sunflower (pith and bark) and rape (straw) are measured and compared. These "green" materials are generally considered as harvesting “residues” and reuse is not always considered. These particles are all produced in most European countries and are the main available agricultural by-products which may be used for building insulation. It should be underlined that those products can be mixed with a binder to manufacture particular insulators (e.g. hemp concrete or sunflower pith/chitosan). The aim here is to deal with raw materials and not a particular mix of particle/binder. The sound absorption and transmission coefficients of those particles are characterized using laboratory experiments. Results show that they can all be used for acoustical absorption and insulation. We apply models to estimate not only the inter- and intra-particles porosities and thus the total porosity of the samples but also the particle and skeletal densities. Then, we show that equivalent fluid models can predict the sound absorption and transmission accurately. Thus inversion of these models enables to estimate microstructural parameters such as the tortuosity, viscous and thermal characteristic lengths and resistivity.

Driven to Disclose: The Psychological Antecedents and Outcomes of Information Sharing

Subjects: subject: Sociology
subject: FOS: Sociology

description: The act of disclosing thoughts, feelings, and information to others has become increasingly prevalent – and the disclosures themselves more public and permanent – in the digital age. This behavior is accompanied by an array of consequences, from the psychological pleasures of social connection and catharsis to the perils of rejection and reputational or material damage. The present dissertation explores this highly consequential behavior from three distinct vantage points. The first paper addresses the question of how best to model disclosure in order to account for actual disclosing behavior (Chapter 2). The second paper investigates whether different subpopulations (namely, men and women) are differentially motivated to disclose and exhibit distinct disclosing patterns (Chapter 3). Finally, the third paper focuses on the expected and actual outcomes of disclosing in a specific context – anonymous online forums – and the contextual features of this setting that mediate any psychological benefits accrued from such disclosures (Chapter 4).

description: To investigate the potential cytotoxicity of copper(II)-based complexes, three coordination compounds with heterocyclic ligands, Cu(pbmbt)Cl2(CH3OH) (1), Cu2(ddbib)2(NO3)4·3CH3OH (2) and Cu3(ttmtmb)2Cl6·2.5H2O (3), which include mononuclear, dinuclear and trinuclear structures, have been synthesized from reactions of corresponding copper(II) salts with 1-((2-pyrazinyl)-1H-benzoimidazol-1-yl)methyl)-1H-benzotriazole (pbmbt), 2-(2,3-dihydropyrazin-2-yl)-1-((4-((2-(2,3-dihydropyrazin-2-yl)-1H-benzo[d]imidazol-1-yl)methyl)phenyl)methyl)-1H-benzo[d]imidazole (ddbib), and 1,1’,1’’-((2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)tris(2-methyl-1H-benzoimidazole) (ttmtmb), respectively. IC50 values revealed that 2 and 3 show strong cytotoxicity, whereas 1 is weakly cytotoxic after being tested against a panel of several human alimentary system carcinoma cell lines (SGC7901, EC109, SMMC7721, and HT29). The number of copper centers and different structures could make a tremendous difference on their cytotoxicity.

description: Gelatinase A (MMP-2) has been studied and proven to play a vital role in the intrusion and metastasis of cancer. Flavonoids influence on molecular and cellular functions of MMP-2 and thus a systematic investigation of flavonoids against the metalloproteolytic activity of MMP-2 has been performed in this study. A fluorescence resonance energy transfer method was used to investigate the inhibitory activities of various flavonoids. Flavone, flavonol and isobavachalcone derivatives showed their inhibitory activity against MMP-2. Surprisingly, the most effective inhibitor was Amentoflavone and its blocking function was superior to other flavonoids. Its IC50 value was 0.689 μM. An induced-fit docking study was carried out to survey its extraordinary activity. The binding mode of Amentoflavone is quite similar to that of (2 ∼ {S})-2-[2-[4-(4-methoxyphenyl) phenyl] sulfanylphenyl] pentanedioic acid complexed with MMP-9. Amentoflavone interacts with the functional zinc and catalytic residue, Glu202. Therefore, the docking study reasonably confirmed the strong inhibitory activity of Amentoflavone.

Cross disciplinary capstone projects for undergraduate engineering double degree students - The good, the bad and the ugly
Creators: name: Dini, K.

Publisher: name: Swinburne
Year: 2024

description: In the context of engineering education, “Final Year Projects (Research)”, also known as “Capstone Projects”, are used to demonstrate students’ final achievement based on the skills, knowledge, and experience gained through the whole engineering degree program. In another words, these subjects are designed to bring together all aspects of students’ experiences. Also, it is believed that students should demonstrate professional skills such as: team work, and communication skills as well as knowledge in the field of engineering. For double degree students studying both Engineering and Business at Swinburne University, Australia the final year projects require students to combine and demonstrate their expertise and skills in both disciplines – Engineering and Business. This paper investigates the pedagogy in the final year research project subjects for double degree students. The researchers are investigating the practises relating to the supervision of these multidisciplinary capstone projects in order to improve the learning and teaching experience for students and academics,. Interviews have been conducted with supervisors from both disciplines. Preliminary findings indicate that most supervisors would be happy to work more collaboratively to develop a clearer understanding of the problem under investigation, using cross disciplinary perspectives, with a key focus on critical points during the semester. A superior solution to the problem being investigated can only be achieved through working collaboratively together.

description: To investigate the potential cytotoxicity of copper(II)-based complexes, three coordination compounds with heterocyclic ligands, Cu(pbmbt)Cl2(CH3OH) (1), Cu2(ddbib)2(NO3)4·3CH3OH (2), and Cu3(ttmtmb)2Cl6·2.5H2O (3), which include mononuclear, dinuclear, and trinuclear structures, have been synthesized from reactions of corresponding copper(II) salts with 1-((2-pyrazinyl)-1H-benzoimidazol-1-yl)methyl)-1H-benzotriazole (pbmbt), 2-(2,3-dihydropyrazin-2-yl)-1-((4-((2-(2,3-dihydropyrazin-2-yl)-1H-benzo[d]imidazol-1-yl)methyl)phenyl)methyl)-1H-benzo[d]imidazole (ddbib), and 1,1′,1′′-((2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)tris(2-methyl-1H-benzoimidazole) (ttmtmb), respectively. IC50 values revealed that 2 and 3 show strong cytotoxicity, whereas 1 is weakly cytotoxic after being tested against a panel of several human alimentary system carcinoma cell lines (SGC7901, EC109, SMMC7721, and HT29). The number of copper centers and different structures could make a tremendous difference on their cytotoxicity.

description: Embelin is an active phytoconstituent known to exhibit a variety of biological activities, especially active against various cancer and tumour cell lines. In the present work, embelin was extracted and isolated from Embelia ribes and was structurally modified by incorporating different fluoro substituted aniline in the quinone motif with a view of enhancing the biological activity. The synthesis was carried out in presence of copper acetate catalyst in a protic solvent, glacial acetic acid to obtain EDFA, ETFA and EOCF and were characterised by various spectral techniques. Embelin and its derivatives were then subjected to in vitro studies in DLA cell lines. Antiangeogenic activities were tested using CAM assay. EOCF was identified as the most active derivative and hence subjected to in vivo studies in tumour induced albino mice. The activity was compared with currently used anticancer drug, cyclophosphamide. The study revealed that EOCF was effective in inhibiting tumour growth.
title: Investigating possibilities to develop textbooks to implement global education in basic education instruction

description: This article focuses on investigating the possibilities of developing textbooks to help implementation of global education in Finnish basic education (first nine years of education). The argumentation is supported by textbook research conducted in the field. Based on research findings, the textbooks guide teaching more than the official national curriculum at the grass-root level in Finland. Moreover, national research conducted in the field reveal that despite the published guidelines and goals, global education teaching has remained modest and uncoordinated. At the same time, national researches have revealed that Finnish pupils’ negative attitudes towards minority groups and immigrants have increased and that regardless of their high level of citizenship knowledge and skills, pupils are not interested in participating in civic actions. Finnish textbooks evaluation studies, in turn, suggest that the above is mainly due to the pedagogical approach and the perspectives represented in the textbooks. According to the findings of my recent research on global education referred in this article, current textbooks in use are not seen as helpful tools in implementing global education. At the basic education level, the respondents consider the main hindrances to be the lack of knowledge and skills in the field and the unavailability of textbooks that are used as main resources in teaching and planning in the country. In conclusion, it is argued that textbooks have great potential to assist in the implementation of the global education programme and to act as real agents of change. As a summary, a list of criteria for textbook evaluation from a global education perspective is suggested.

description: Experiments were carried out according to the NORDTEST protocol to study the moisture buffer value of various wall assemblies incorporating hemp-lime. The following assemblies were tested: a base-case assembly of hemp-lime without any coating, hemp-lime with lime plaster on the upper surface of the sample, hemp-lime with breather membrane, hemp-lime with breather membrane and air layer and plasterboard, hemp-lime with air layer and plaster board. Two tests were carried out with following two air velocities over the buffering surfaces during the moisture uptake cycles: 0.3 m/s and 0.6 m/s. It was observed that, while use of coatings and inner layers reduced the moisture buffer values of the assemblies, yet the reduced values were comparable with the moisture buffer values of some other best performing building materials in their exposed conditions. It was also observed that change of air velocity had higher impact on the moisture buffer values of the exposed hemp-lime and the hemp-lime with lime plaster than on that of the other assemblies.

Physiologie de la croissance chez la vigne: Influences foliaires

description: Les influences observées dans ces différentes expériences peuvent être classées en deux catégories, effets trophiques et effets morphogénétiques. Du point de vue trophique nous apportons la preuve expérimentale d'un fait essentiel jusqu'alors seulement soupçonné, la possibilité de mobilisation des réserves glucidiques de la souche par les parties végétatives des pousses lorsque l'activité photosynthétique est déficiente et ce pendant toute la durée d'un cycle végétatif. Deux autres faits sont confirmés: l'effet dépressif de la réduction de la surface foliaire assimilatrice sur l'évolution des grappes mais aussi la possibilité pour toutes les grappes d'un cep d'accéder à un «pool» commun des assimilats et ce, quelle que soit leur situation vis à vis des feuilles. Les résultats acquis par ces expériences nous ont permis de faire une première approche de certaines influences morphogénétiques de la feuille chez la vigne: • influence foliaire sur la croissance internodale, • participation des feuilles à l'arrêt de croissance des pousses à la fin du cycle végétatif, • influence inhibitrice des feuilles adultes portées par un rameau donné sur le bourgeon terminal d'une pousse voisine privée de la totalité de ses feuilles. Cette influence est telle qu'elle conduit à la mort du bourgeon et finalement de toute la pousse défoliée. Shoot growth on grapevines in the presence or absence of leaves In experiments with vines of cv. Pinot noir, ail or half the shoots per vine were continuously defoliated from bud burst onwards and compared with shoots on vines without defoliation. The two methods of defoliation gave different responses. Defoliation of ail shoots per vine reduced shoot length because of shorter internodes although leaf initiation continued for longer and at a rate comparable to that of shoots on control vines. The flowers on the defoliated shoots failed to set. Defoliation of only half the shoots per vine caused the defoliated shoots to die back to the nodes that carried inflorescences. Their flowers set and developed into mature but somewhat smaller berries. On these vines, the presence of mature leaves nearby was responsible for the behaviour of the defoliated shoots.

description: The phytochemical investigation of Psidium guajava leaves led to the isolation of total nineteen compounds which belongs to meroterpenoids, flavonoid, phenolics, and triterpenoids. The compounds were isolated using extensive chromatography techniques and identified as psiguanol (4), as new compound along with guajadial (1), psidial A (2), β-caryophyllene (3), quercetin (5), avicularin (6), guaijaverin (7), hyperin (8), rutin (9), ursolic acid (10), corosolic acid (11), asiatic acid (12), β-sitosterol (13), β-sitosterol-D-glucoside (14), ellagic acid (15), 3,3',4'-trimethylellagic acid 4-O-glucoside (16), protocatechuic acid (17), gallic acid (18), and tricosanoic acid (19) as known molecules. The compound 16 was isolated for the first time from this plant. The isolated compounds were evaluated for vasorelaxation activity in rat aorta cells and it was observed that compound 4 exhibited the most potent vasorelaxation response in the ex-vivo model in isolated rat aorta cells. Mechanistically, the vasorelaxation activity of 4 was mediated through cGMP-dependent BKCa channel opening.
