News Consumption Habits of Culturally Diverse Australians in the Digital Era: Implications for Intercultural Relations

It is well-documented that news media (both traditional and social) have a significant impact on intercultural relations in contemporary societies. This paper compares results of two surveys where we asked Australians about their news sources. The study shows that Australian news consumers from diverse cultural backgrounds are alienated from Australian mainstream news media, increasingly relying on online and social media sources for their information. The paper situates this empirical research in the contemporary articulation of uses and gratification theory to understand audiences’ preferred media sources for news and information and the potential implications for intercultural relations in Australia.     

Allergens/Antigens,Toxins and Polyketides of Important <Emphasis Type="Italic">Aspergillus</Emphasis> Species

The medical, agricultural and biotechnological importance of the primitive eukaryotic microorganisms, the Fungi was recognized way back in 1920. Among various groups of fungi, the Aspergillus species are studied in great detail using advances in genomics and proteomics to unravel biological and molecular mechanisms in these fungi. Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Aspergillus parasiticus, Aspergillus nidulans and Aspergillus terreus are some of the important species relevant to human, agricultural and biotechnological applications. The potential of Aspergillus species to produce highly diversified complex biomolecules such as multifunctional proteins (allergens, antigens, enzymes) and polyketides is fascinating and demands greater insight into the understanding of these fungal species for application to human health. Recently a regulator gene for secondary metabolites, LaeA has been identified. Gene mining based on LaeA has facilitated new metabolites with antimicrobial activity such as emericellamides and antitumor activity such as terrequinone A from A. nidulans. Immunoproteomic approach was reported for identification of few novel allergens for A. fumigatus. In this context, the review is focused on recent developments in allergens, antigens, structural and functional diversity of the polyketide synthases that produce polyketides of pharmaceutical and biological importance. Possible antifungal drug targets for development of effective antifungal drugs and new strategies for development of molecular diagnostics are considered.     

Effects of Dialect on American and British Children's Spelling

Two experiments were carried out to compare the spelling of children who speak General American English and children who speak Southern British English. The first dialect is rhotic (/r/may occur after a vowel in a syllable), and the second is nonrhotic (/r/may not occur in this context). Young children's spelling errors reflected the characteristics of their dialect. For example, American children with spelling ages of about 6–7½ often misspelled hurt as "hrt" whereas British children of similar spelling levels were more likely to misspell it as "hut." Such errors were uncommon by spelling ages of greater than 7½. Even at these spelling ages, however, the British children made overgeneralization errors that reflected their dialect. For example, they sometimes spelled bath as "barth" based on the fact that bath contains the same vowel sound as card in their dialect. The results show that phonology plays an important role in children's spelling development.     

Educational Neuroscience: Defining a New Discipline for the Study of Mental Representations

ABSTRACT— Is educational neuroscience a “bridge too far”? Here, we argue against this negative assessment. We suggest that one major reason for skepticism within the educational community has been the inadequate definition of the potential role and use of neuroscience research in education. Here, we offer a provisional definition for the emerging discipline of educational neuroscience as the study of the development of mental representations. We define mental representations in terms of neural activity in the brain. We argue that there is a fundamental difference between doing educational neuroscience and using neuroscience research results to inform education. While current neuroscience research results do not translate into direct classroom applications, educational neuroscience can expand our knowledge about learning, for example, by tracking the normative development of mental representations. We illustrate this briefly via mathematical educational neuroscience. Current capabilities and limitations of neuroscience research methods are also considered.     

Children’s orthographic representations in English and Greek

Two experiments were conducted to compare the development of orthographic representations in children learning to read English and Greek. Nonsense words that either shared both orthography and phonology at the level of the rhyme with real words (comic-bomic), phonology only (comic-bommick), or neither (dilotaff) were created for each orthography. Experiment 1 compared children’s reading of bisyllabic and trisyllabic nonsense words likebomic vs.bommick, taffodil vs.tafoddyl, and found a significant facilitatory effect of orthographic rhyme familiarity for English only. Experiment 2 compared children’s reading of trisyllabic nonsense words that either shared rhyme phonology with real words (tafoddyl) or did not (dilotaff). Significant facilitation in reading accuracy was found for shared rhyme phonology in English, with a significant speed advantage in Greek. These results are interpreted in terms of the level of phonology that is represented in the orthographic recognition units being developed by children who are learning to read more and less transparent orthographies.     

Hyper prolinuria and hyper-hydroxy prolinuria in children with mental retardation

Three thousand cases with mental retardation referred from different hospitals were screened for aminoacid disorders. Among them one case of hyperprolinuria and another case of hyperprolinuria with hyper hydroxyprolinuria were detected. These are the first cases to be reported from the state of Andhra Pradesh.
