Schools attempting to engage with the families of all learners, including those with culturally and linguistically diverse backgrounds recognize the importance of effective oral and written communication. The aim of this study is to determine if school generated written communication created by an urban school district serving a culturally and linguistically diverse population in the Northeast of the US adhered to the principles of plain English. This exploratory research examined exemplar pieces of written school generated communication, using different forms of linguistic analysis to determine whether the communication contained elements recognized to facilitate or impede the comprehensibility of each piece of communication. Additionally, a text assessment tool which can help schools to analyze the written text communication they send to families was developed and refined.

This study examined oral education components that could be successfully implemented with culturally and linguistically diverse deaf and hard of hearing (DHH) children and their families. A literature review of oral program strategies used with culturally diverse families and their children with special needs, and federal guidelines related to programs serving DHH children were conducted. Recent statistics of children in programs for DHH students who are from racially and linguistically diverse backgrounds were discussed. Additional data sources included classroom observations and multidisciplinary interviews. The data obtained was utilized to design a framework for oral programs to support culturally and linguistically diverse DHH children and their families.

The process of divorce as a family change process including outcomes and consequences has received considerable research attention in the western context. However, the experience of divorce for children within specific ethnic contexts has been rather limited leading to poor planning and practice provision with diverse families. By drawing upon an empirical qualitative study of British Indian adult children, this paper will make a case for recognising diverse needs within specific historical, socio-cultural and developmental contexts. There is a need to acknowledge these contexts in policy design to establish practice that is flexible, accessible and relevant to the needs of different and diverse communities. Results indicate that areas of impact may be similar to those identified by other studies within the literature review. However, the experiences, expressions, implications and larger consequences of impact are located within specific socio-cultural contexts. In support of this, major findings of the study (outlined below) will be discussed - Context: patriarchy, stigma, immigration; Impact: economic, social, emotional, career/education, physical; Coping: psychological strategies, physical strategies, social strategies, sources of support.

Eight novel families of miniature inverted repeat transposable elements (MITEs) were discovered in the African malaria mosquito, Anopheles gambiae, by using new software designed to rapidly identify MITE-like sequences based on their structural characteristics. Divergent subfamilies have been found in two families. Past mobility was demonstrated by evidence of MITE insertions that resulted in the duplication of specific TA, TAA, or 8-bp targets. Some of these MITEs share the same target duplications and similar terminal sequences with MITEs and other DNA transposons in human and other organisms. MITEs in A. gambiae range from 40 to 1340 copies per genome, much less abundant than MITEs in the yellow fever mosquito, Aedes aegypti. Statistical analyses suggest that most A. gambiae MITEs are in highly AT-rich regions, many of which are closely associated with each other. The analyses of these novel MITEs underscored interesting questions regarding their diversity, origin, evolution, and relationships to the host genomes. The discovery of diverse families of MITEs in A. gambiae has important practical implications in light of current efforts to control malaria by replacing vector mosquitoes with genetically modified refractory mosquitoes. Finally, the systematic approach to rapidly identify novel MITEs should have broad applications for the analysis of the ever-growing sequence databases of a wide range of organisms.

Abundant research has shown that poverty has negative influences on young child academic and psychosocial development, and unfortunately, disparities in school readiness between low and high income children can be seen as early the first year of life. The largest federal early care and education intervention for these vulnerable children is Early Head Start (EHS). To diminish these disparate child outcomes, EHS seeks to provide community based flexible programming for infants and toddlers and their families. Given how relatively recent these programs have been offered, little is known about the nuances of how EHS impacts infant and toddler language and psychosocial development. Using a framework of Community Based Participatory Research (CBPR) this paper had 5 goals: 1) to characterize the associations between domain specific and cumulative risk and child outcomes 2) to validate and explore these risk-outcome associations separately for Children of Hispanic immigrants (COHIs), 3) to explore relationships among family characteristics, multiple environmental factors, and dosage patterns in different EHS program types, 4) to examine the relationship between EHS dosage and child outcomes, and 5) to examine how EHS compliance impacts child internalizing and externalizing behaviors and emerging language abilities. Results of the current study showed that risks were differentially related to child outcomes. Poor maternal mental health was related to child internalizing and externalizing behaviors, but not related to emerging child language skills. Although child language skills were not related to maternal mental health, they were related to economic hardship. Additionally, parent level Spanish use and heritage orientation were associated with positive child outcomes. Results also showed that these relationships differed when COHIs and children with native-born parents were examined separately. Further, unique patterns emerged for EHS program use, for example families who participated in home-based care were less likely to comply with EHS attendance requirements. These findings provide tangible suggestions for EHS stakeholders: namely, the need to develop effective programming that targets engagement for diverse families enrolled in EHS programs.

The capacity of educators to work in partnership with families is considered to be a hallmark of quality practice in education and care. The rationale is that ‘children thrive when families and educators work together in partnership to support young children’s learning’ (DEEWR 2009, p. 9).To support genuine partnerships, the Brisbane South Professional Support Network (PSN) is leading a collaborative project, with the Health and Community Services Workforce Council and Queensland University of Technology (QUT), known as the ‘Family Participation in ECEC project’. The overarching aim of the project is to investigate different perspectives of family partnership in ECEC, with a focus on information sharing, information seeking and family participation,to build educator capacity to establish and maintain genuine partnerships with families. Maintaining a practical focus, and linking to the National Quality Framework for Early Childhood Education and Care (Quality Area 6), the study findings offer insight into the different ways that diverse families and educators may view and experience partnership, and as such provide a sound basis for critical reflection, professional learning and improved practice.

Early education in Australia encompasses both early education and care(ECEC) and the early years of school. Educational approaches to cultural and linguistic diversity have varied not only by sector but also by jurisdiction based on distinct curriculum frameworks and policies. In Australian early education, provision for cultural and linguistic diversity has been framed largely by multicultural discourse, as defined by a complex history of progressive, yet often superficial reforms. Current initiatives serve to change this trajectory and the positioning of stakeholders. The incorporation of intercultural rather than multicultural approaches offers new possibilities for early education and directs attention to real challenges for ECEC. They re-position Aboriginal and Torres Strait Islanders as the First Australians, and direct attention to both Australia’s social, cultural and linguistic diversity and to the role of early childhood educators in enacting more inclusive pedagogies. Challenges yet to be addressed include the cultural understanding of Australian early childhood educators, particularly those who identify as Anglo- Australian, deeper policy enactment in pedagogic practice and negotiation with diverse families and communities. This paper will address the historical and current policy contexts of intercultural early education in Australia, the development of intercultural initiatives, and emerging issues as national policies are introduced. The discussion draws on responses to intercultural early education in New Zealand and Canada to consider approaches to intercultural priorities in Australia. The paper will attend predominantly to Aboriginal and Torres Strait Islander perspectives as a core element of change in Australian early childhood policy, focusing on ECEC.

Increased longevity and the need to fund living and care expenses across late old age, greater proportions of blended and culturally diverse families and concerns about the increasing possibility of contestation of wills highlight the importance of understanding current will making practices and intentions. Yet, there is no current national data on the prevalence of wills, intended beneficiaries, the principles and practices surrounding will making and the patterns and outcomes of contestation. This project sought to address this gap. This report summarises the results of a four year program of research examining will making and will contestation in Australia. The project was funded by the Australian Research Council (LP10200891) in conjunction with seven Public Trustee Organisations across Australia. The interdisciplinary research team with expertise in social science, social work, law and social policy are from The University of Queensland, Queensland University of Technology and Victoria University. The project comprised five research studies: a national prevalence survey, a judicial case review, a review of Public Trustee files, an online survey of will drafters and in-depth interviews with key groups of interest. The report outlines key findings. On the basis of the evidence provided recommendations are presented to support the achievement of these policy goals: increasing will making in the Australian population, ensuring that the wills of those Australians who have taken this step reflect their current situation and intentions, and reducing will contestation.

Twelve microsatellite DNA markers were isolated in the spot-tail shark (Carcharhinus sorrah) and nine were isolated in Australian black-tip shark (Carcharhinus tilstoni). These loci plus 18 others developed for sharks from the genera Negaprion, Ginglymostoma, Carcharodon and Isurus were tested for amplification success on four species of Carcharhinus (including C. sorrah and C. tilstoni) and four other species representing three diverse families. Cross-amplification was most common within families. Five loci were subsequently tested for polymorphism on 50 C. sorrah and 60 C. tilstoni. The number of alleles per locus was two to 24 and the average heterozygosity was 0.54 (range 0.16-0.87) for C. sorrah and 0.64 (range 0.44-0.78) for C. tilstoni. These loci may be useful tools for genetic analyses of the Carcharhinidae.

The Australian government has recognised the importance of early childhood education and care (ECEC) in recent years. With over one million Australian children accessing early childhood education provision every day (Productivity Commission, 2014), today’s children are a generation who spend a large part of their early years in some form of out-of-home child care. Early chapters in this text have discussed a range of people, theories and approaches that inform the development of ECEC. Early childhood pedagogical practice is an eclectic mix of these ideas. This chapter begins with an overview of the ways young children learn in early childhood education, highlighting play-based learning as a pedagogical response to our understandings about children. Next the chapter outlines areas that have more recently influenced ECEC including international models of early childhood education, neuroscience, studies of young children, economic research and social justice principles. Drawing on the reflections of educators working in various ECEC contexts, the chapter then presents four topics encountered by educators as part of their everyday work with diverse communities. These topics include: • the educational program for children in the early years • relationships and partnerships with diverse families • professional accountabilities, and • changing constructions of childhood.

角蟾科(Megophryidae)是以角蟾属(Megophrys Kuhl and Van Hasselt, 1822)为模式属而建立的,隶于无尾目(Anura),变凹型亚目(Anomocoela)。角蟾科包括2 亚科11 属142 种,分布于东洋界,从巴基斯坦、中国西部向东直到菲律宾和苏达群岛;中国有9 属75 种分布于华中和华南地区。角蟾科被认为是原始的两栖动物之一,其分类学、系统学、生态学、动物地理学的研究均深受中外科学家的瞩目。近年来,通过形态学、古生物学、细胞学、生态学、支序系统学的研究,角蟾科的分类与系统学研究取得了较大进展。与成体形态和分子系统学研究结果相比较,蝌蚪的研究存在更多的问题和挑战,尚需深入研究:(1)角蟾科蝌蚪的形态多样性分析;(2)角蟾科的系统发育关系与蝌蚪的演化,以及口漏斗的起源;(3)角蟾科蝌蚪表型分化与栖息环境和觅食行为的适应演化。针对上述问题,本文对角蟾科9 属30 种蝌蚪的形态特征,包括外部宏观形态和口器外部结构特征、口器内部显微结构、唇齿和角质颌的亚显微结构作了深入细致、多层次的比较研究;通过12s rRNA 和cytochrome b 基因构建最大简约树,采用贝叶斯系统发育进行分析,蝌蚪型的演化采用祖先性状的重建方法分析;得到如下结论:1)初步将角蟾科蝌蚪分为4 种类型;并且建立了2 种新的角蟾科蝌蚪类型。A 型:拟髭蟾型蝌蚪,该型蝌蚪包括拟髭蟾属、髭蟾属、齿蟾属和齿突蟾属的物种;B 型:新类型,掌突蟾型蝌蚪,该型蝌蚪在本文中包括掌突蟾属、小臂蟾属的物种;C 型:新类型,短腿蟾型蝌蚪,一种特化类型,该型蝌蚪在本文中仅包括短腿蟾属的物种;D 型:角蟾型蝌蚪,该型蝌蚪在本文中包括无耳蟾属、小口拟角蟾属和异角蟾属的物种。2)对角蟾科的分类进行了修订:(1)支持角蟾科两个亚科的分类系统;(2)角蟾亚科包括拟角蟾属、异角蟾属、无耳蟾属和短腿蟾属;该亚科形态差异小,系统学关系比较复杂,暂不作族级分类的再划分;(3)拟髭蟾亚科分为2 个族:拟髭蟾族,该族物种具有类型A 的蝌蚪,包括4 个属:拟髭蟾属、髭蟾属、齿蟾属、齿突蟾属;掌突蟾族,该族物种具有类型B 的蝌蚪,包括2 个属:掌突蟾属和小臂蟾属。3)结合分子系统进化关系探讨了4 种蝌蚪类型的演化。(1)角蟾科蝌蚪的最近共同祖先来自于一类具有拟髭蟾型蝌蚪性状的蝌蚪;(2)掌突蟾型蝌蚪和角蟾亚科的蝌蚪是由具有拟髭蟾型蝌蚪性状的祖先蝌蚪分别演化而来;(3)短腿蟾型蝌蚪是角蟾型蝌蚪的一种特化类型;(4)外群蝌蚪具有与拟髭蟾型蝌蚪相似的性状,进一步印证了类拟髭蟾型蝌蚪是角蟾科蝌蚪的最近共同祖先的假说;(5)具有口漏斗的蝌蚪类型是由不具口漏斗的蝌蚪类型演化而来,在角蟾科中口漏斗是一种衍生性状。4)分析了角蟾科四种蝌蚪类型与栖息环境的适应演化。(1)角蟾科蝌蚪的口部和体形的变化反映了该科蝌蚪由缓流向类似静水生境的回水凼的渐变式适应,角蟾科蝌蚪的形态显示了多方面的适应变化;(2)随着蝌蚪类型由A 向D的演化,当水速较大时,拟髭蟾型的蝌蚪营流水攀吸型生活方式;当水速递减时,掌突蟾型蝌蚪营流水附着型生活方式;当水速进一步递减时,具有较小口漏斗的短腿蟾型蝌蚪和具有大漏斗的角蟾型蝌蚪营流水浮泳型生活。角蟾科蝌蚪对于水流递减的适应演化说明蝌蚪的生态学适应是具有进化意义的;(3)蝌蚪口器内部结构的分化揭示了蝌蚪和食性的适应关系,蝌蚪以口部的唇齿与角质颌刮取或吞吸水中的物质,然后,通过口乳突有选择地过滤进入口腔中食物。拟髭蟾亚科蝌蚪的唇齿多而窄,唇齿间距宽,颌鞘粗而稀,反映了其植食性为主的特点;它们的舌前乳突一般为指状,在口腔入口处所占面积小,其机械过滤的作用很多被唇齿和角质颌分担了;而角蟾亚科的蝌蚪,其角质颌弱,其舌前乳突一般为匙状,几乎填满了口腔入口处,因此舌前乳突起了主要的机械过滤作用。The family Megophryidae is the largest and most diverse families inArchaeobatrachia, and most of its species occur in India, Pakistan, and eastward intoChina, Southeast Asia, Borneo and the Philippines to the Sunda Islands. Currently thefamily includes 142 species have been grouped into two subfamilies, Megophryinaeand Leptobrachiinae. The mountains of central and southern China are rich in speciesof Megophryidae, 75 species belong to 9 genera and two subfamilies.The family was supposed to be ideal materials of studies in many fields of biology,such as taxonomy, evolution, systematics, ecology, and biogeography. Recently, therehave a great development in taxonomy and systematics of megophryids throughstudied by morphology, paleontology, cytology, ecology, and cladistics. However,larvae of megophryids were generally unknown, although the tadpoles might be veryimportant for above studies.In this paper, we examined the evolutionary scenario of the tadpoles’ morphologyin the context of a phylogenetic framework. Our objectives are (1) to evaluate thedivergence of larval body shape and oral discs in the family Megophryidae, (2) toexplore the evolutionary trends of the larvae in megophryidae, and test if thefunnel-shaped oral disc is apomorphic, and (3) to explore the relationship of the larvalstructure, diet and microhabitat.We examined larval morphology of 30 megophryid species, the larval body shape,oral discs, the buccopharyngeal cavity, and jaw sheaths and denticles of the Chinesemegophryid frogs were re-examined. We constructed a phylogeny of the species on thebasis of published mitochondrial cytochrome b and 16S rRNA gene segments usingpartitioned Bayesian analyses. Furthermore, hypothetical changes of larval morphologywere inferred using parsimony principle on the phylogeny. The results showed that:1) Four tadpole types in Megophryidae. The larval morphological charactersseries in Chinese megophryids fall into four general categories according to the bodyshape and oral discs: (A) Leptobrachiini type, species from genera Leptobrachium,Oreolalax, Scutiger and, Vibrissaphora share this type of tadpoles. (B) Leptolalax type,species of genus Leptolalax have this type of tadpoles. (C) Brachytarsophrys type,species of the genus Brachytarsophrys have this type of tadpoles. (D) Megophryinitype, species of the genera Atympanophrys, Ophryophryne, and Xenophrys share this type of tadpoles. Of which B and C are two novel types.2)Taxonomic implications. The present study leads us to reconsider the generalclassification of tribes attributed to members of Megophryidae. More specifically,concerning the phylogenetic relationships and the two novel tadpole types describedherein, we propose a provisional taxonomy for the family but suggest that further taxasampling of other megophryids be performed to confirm this taxonomic change. TheMegophryidae is composed of two subfamilies (Leptobrachiinae and Megophryinae).The Leptobrachiinae was recogonized the two tribes: (1) tribe Leptobrachiini sensuDubois, corresponding to the tadpole of type A, including four genera, i.e.,Leptobrachium, Oreolalax, Scutiger and, Vibrissaphora; (2) tribe Leptolalaxini,corresponding to the tadpole of novel type B, including two genera, i.e., Leptolalaxand Leptobrachella. However, the relationships among the genera of Megophryinaewere largely unresolved, they recognized no monophyletic groups above the generalevel. A more thorough sampling will likely foster a better taxonomic solution.3) The larval evolutionary scenario in Megophryidae.Type A is characteristicof normal-mouthed with multiple tooth rows, representing the tadpole type of theMRCA of Chinese megophryids. Type B is characteristic of normal-mouthed withreduced tooth rows, prolonging labium, and integumetary glands. Type C ischaracteristic of no labial teeth and smaller umbeliform oral disc. Type D ischaracteristic of no labial teeth, enlarged umbeliform oral disc, representing the tadpoleof the MRCA of subfamily Megophryinae. A previous hypothesis, referring tofunnel-shaped oral discs as an apomorphy, is supported.4) The larval adaptation to habitats in Megophryidae. Tadpoles generallyadhere to substrates using their mouths, and the microhabitat that the tadpoles occupyreflects the degree of adhesion and oral complexity. The morphological changes inmegophryid tadpoles virtually allow a progressive adaptation to a changing habitatfrom faster water to slower water. Within the tadpoles of Type A to type D, the TOTbecomes smaller and smaller, and the oral disc orientates from anteroventral toumbelliform upturned, and eye position orientates from dorsal to lateral, and the trunkis more and more depressed and tail becomes relatively longer and slender. Within therunning water, the normal-mouthed with multiple tooth rows of Leptobrachiini tadpoles are correlated with lotic-suctorial, benthic feeders with anteroventral oraldisc and the largest body. With the water’s velocity decreasing, the lotic-adherentfeeders of Leptolalax tadpoles have tube-shaped labium with reduced tooth rows andintegumetary glands. And then, the smaller umbeliform in Brachytarsophrys tadpolesand the enlarged umbeliform oral disc in the Megophryini tadpoles are inhabitmicrohabitats of non-flowing backwaters of rivers, indicative of adaptive traits oflotic-neustonic surface feeders. The scheme of megophryid tadpoles andmicrohabitats provided the first clear evidence which congruent with the hypothesis ofAltig and Johnston (1989). The ecological divergence plays a general role in thedivergence and evolution of megophrid larvae. There is a definite correlation amongthe buccopharyngeal cavity, diet and feeding mechanisms, the tadpole graze orswallow the food particles, then through papillae which like a sieve and sort out foodparticles to the oesophagus. The tadpole of Leptobrachiinae possess multiple toothrows, wide intertooth distance as well as thick and sparse jaw sheath, these tadpolesinhabit bottom of the streams and graze on epiphyton or major detritus of organicmatter on the substrates, their prelingual papillae like single finger, the mechanicalpurpose of papillae served share in by tooth and jaw. The tadpoles of Megophryinaeoccur near the water surface of small streams and are the filter feeder, their dietincludes plankton and organic debris floating on the water surface, those tadpolepossess weak jaw, their prelingual papillae like spoon, the mechanical purpose ofpapillae served mostly for sieve.

Un objectif majeur en chimie organique est le développement de méthodes de synthèses générales, simples et peu coûteuses permettant la modification efficace des ressources naturelles en différents produits d’intérêt public. En particulier, la recherche de méthodes chimiosélectives et de méthodes dites « vertes » représente un intérêt croissant pour le secteur industriel (dont le domaine pharmaceutique). En fait, l’application en synthèse sur grande échelle de procédés catalytiques, sélectifs et utilisant des conditions douces permet de réduire le volume de déchets et la demande énergétique, minimisant ainsi les coûts de production et les effets néfastes sur l’environnement. Dans ce contexte, le groupe de recherche du Professeur André B. Charette de l’Université de Montréal s’intéresse au développement de méthodes générales et chimiosélectives permettant la transformation de fonctionnalités aisément accessibles tels que les amides et les alcools. La fonction amide, aussi appelée liaison peptidique dans les protéines, est présente dans diverses familles de molécules naturelles et est couramment employée comme intermédiaire synthétique dans la synthèse de produits d’intérêt pharmaceutique. Le groupement alcool est, quant à lui, l’une des fonctionnalités les plus abondantes dans la nature, intrinsèquement et largement utilisé en chimie de synthèse. Dans le cadre de cette thèse, des transformations simples, générales et chimiosélectives ont été réalisées sur des amides secondaires et tertiaires, ainsi que sur des alcools primaires et secondaires. La première partie de ce manuscrit se penche sur l’activation de la fonction amide par l’anhydride triflique (Tf2O), suivie de l’addition nucléophile de différents réactifs permettant ainsi la formation de plusieurs groupements fonctionnels versatiles, parfois indispensables, couramment employés en chimie organique tels que les aldimines, les aldéhydes, les amines, les cétones, les cétimines et des dérivés de la fonction amidrazone. Cette dernière fonctionnalité a également été utilisée dans des réactions successives vers la formation d’hétérocycles. De ce fait, des 1,2,4-triazoles ont été formés suite à une cyclodéshydratation initiée en conditions thermiques et faiblement acides. D’autre part, des 3-aminoindazoles ont été synthétisés par une fonctionnalisation C–H catalysée par un sel de palladium (II). La deuxième partie de la thèse est consacrée à la réaction de Mitsunobu en conditions acides, permettant ainsi la substitution nucléophile d’alcools en présence de carbamines (ou amines ne possédant pas de groupement électro-attracteurs). Ce type de nucléophile, basique lorsqu’utilisé comme base libre (avec un pKa se situant au-dessus de 13 dans le DMSO), n’est intrinsèquement pas compatible dans les conditions standards de la réaction de Mitsunobu. Contrairement aux conditions usuelles multi-étapes employant la réaction de Mitsunobu, la méthode développée au cours de cette étude permet la formation d’amines substituées en une seule étape et ne requiert pas l’emploi de groupements protecteurs.

This study examined culturally and linguistically diverse families with deaf and hard of hearing children. A literature review consisted of looking at the rate of immigration to the United States, English speaking parents of children who are deaf and hard of hearing, bilingual education, and the obstacles bilingual parents of children who are deaf and hard of hearing may face. The data obtained was used to compile a list of resources for parents of children who are deaf and hard of hearing available in languages other than English in order to assist these families.
