High school may not be enough: An investigation of Asian studentsâ eligibility for post-secondary education
Post-secondary education has increased in importance as the worldâs economies become more knowledge-based. Employment trends suggest that a high school diploma may be insufficient in some jurisdictions to meet the skills and demands of the 21st century workplace (HRSDC, 1998). In addition, immigration trends are resulting in more ethnic and cultural diversity in North American schools (cf., Goldenberg, 2006). The problem is that little research has been conducted to explore the participation of students from a variety of language or ethnic groups in Post- Secondary Education Programs (PSEPs) or to explore factors that may influence their eligibility to participate. According to Statistics Canada, by 2031, one in four Canadians will have been born in another country. Immigrants from Asia make up the largest group moving to urban centres around North America (CBC, 2010). This trend has implications for teachers who need to know how to meet these learnersâ needs. While participation rates in PSEPs in Canada are steadily increasing (Shaienks, Gluszynski, & Bayard, 2008), it is unclear how immigrant student groups are faring. The goal of this exploratory study was to explore factors that influence Asian studentsâ eligibility for PSEPs.L'importance de l'Ă©ducation post-secondaire a augmentĂ© en parallĂšle avec les Ă©conomies mondiales qui deviennent de plus en plus des sociĂ©tĂ©s de la connaissance. Les tendances en matiĂšre d'emploi suggĂšrent qu'un diplĂŽme d'Ă©tudes secondaires peut ĂȘtre insuffisant dans certaines juridictions pour rĂ©pondre aux compĂ©tences et aux exigences du monde du travail au XXIĂšme siĂšcle (RHDCC, 1998). En outre, l'Ă©volution de l'immigration se traduit par une plus grande diversitĂ© ethnique et culturelle dans les Ă©coles nord-amĂ©ricaines (cf Goldenberg, 2006). Le problĂšme est que peu de recherches ont Ă©tĂ© menĂ©es afin d'Ă©tudier la participation des Ă©tudiants ayant des antĂ©cĂ©dents culturels et linguistiques diffĂ©rents dans les programmes de l'Ă©ducation post-secondaire (PEPSs), ou pour Ă©tudier les facteurs qui peuvent influer sur leur admissibilitĂ©. Selon Statistique Canada, en 2031, un Canadien sur quatre sera nĂ© dans un autre pays. Les immigrants en provenance d'Asie forment le groupe le plus important se dĂ©plaçant vers les centres urbains Ă travers l'AmĂ©rique du Nord (SRC, 2010). Cette tendance a des implications pour les enseignants qui doivent savoir comment rĂ©pondre aux besoins de ces apprenants. Bien que le taux de participation dans les PEPSs au Canada est en constante augmentation (Shaienks et coll., 2008), il est difficile de savoir comment les groupes d'Ă©tudiants immigrants se dĂ©brouillent. L'objectif de cette Ă©tude exploratoire Ă©tait d'analyser les facteurs qui influent sur l'admissibilitĂ© des Ă©tudiants asiatiques dans les PEPSs

Ancient Plasmodium genomes shed light on the history of human malaria
Malaria-causing protozoa of the genus Plasmodium have exerted one of the strongest selective pressures on the human genome, and resistance alleles provide biomolecular footprints that outline the historical reach of these species1. Nevertheless, debate persists over when and how malaria parasites emerged as human pathogens and spread around the globe1,2. To address these questions, we generated high-coverage ancient mitochondrial and nuclear genome-wide data from P. falciparum, P. vivax and P. malariae from 16 countries spanning around 5,500 years of human history. We identified P. vivax and P. falciparum across geographically disparate regions of Eurasia from as early as the fourth and first millennia bce, respectively; for P. vivax, this evidence pre-dates textual references by several millennia3. Genomic analysis supports distinct disease histories for P. falciparum and P. vivax in the Americas: similarities between now-eliminated European and peri-contact South American strains indicate that European colonizers were the source of American P. vivax, whereas the trans-Atlantic slave trade probably introduced P. falciparum into the Americas. Our data underscore the role of cross-cultural contacts in the dissemination of malaria, laying the biomolecular foundation for future palaeo-epidemiological research into the impact of Plasmodium parasites on human history. Finally, our unexpected discovery of P. falciparum in the high-altitude Himalayas provides a rare case study in which individual mobility can be inferred from infection status, adding to our knowledge of cross-cultural connectivity in the region nearly three millennia ago.This project was funded by the National Science Foundation, grants BCS-2141896 and BCS-1528698; the European Research Council (ERC) under the European Unionâs Horizon 2020 programme, grants 851511-MICROSCOPE (to S.

Cachimbos europeus de cerùmica branca, séculos XVI ao XIX: parùmetros båsicos para anålise arqueológica
O tabaco foi introduzido na Europa no final do sĂ©culo XV. Desde entĂŁo, uma das formas mais comuns para o seu consumo foi o cachimbo, alĂ©m do rapĂ©, do tabaco de mascar, do charuto e, mais recentemente, dos cigarros. Os cachimbos de cerĂąmica branca, largamente produzidos e utilizados na Europa desde o sĂ©culo XV, sĂŁo encontrados em sĂtios arqueolĂłgicos histĂłricos ao redor do mundo, incluindo no Brasil, em decorrĂȘncia do comĂ©rcio internacional, que gradualmente se intensificou apĂłs o inĂcio da conquista europeia. Eles funcionam como excelentes elementos para datação de sĂtios e estratos arqueolĂłgicos, tendo sido estudados em vĂĄrios paĂses a partir dessa abordagem. Ainda, esse tipo de artefato, mais que fornecer dataçÔes, permite identificar redes comerciais entre naçÔes e desenvolver discussĂ”es de cunho social e cultural. Contudo, eles foram pouco estudados no Brasil. Visando contribuir com os estudos nacionais dessa categoria material, este artigo oferece uma revisĂŁo da literatura internacional acerca do histĂłrico da produção dos cachimbos europeus de caulim, incluindo apresentação dos principais centros produtores; da morfologia e decoração desses produtos, considerando a cronologia do fabrico; e dos mĂ©todos de anĂĄlise dos diferentes cachimbos de caulim no Ăąmbito da arqueologia histĂłrica.Tobacco was introduced in Europe at the end of the 15th century. Since then, one of the most traditional means for its use has been the pipe, next to the powder version, chewing, cigars, and, more recently, cigarettes. White clay tobacco pipes, widely produced and used in Europe since the 15th century, are found in historical archaeological sites around the world, including Brazil, due to international trade, which gradually intensified with the European conquest of the New World. They are excellent guides for dating archaeological sites and layers. In addition, this type of artifact, more than a dating tool, permits identifying trading networks between nations and developing discussions of cultural and social nature. These pipes, however, have been understudied in Brazil. In order to contribute to studies of this type of artifact in our country, this paper offers a revision of the international literature on the history of clay pipe production in Europe, including the presentation of main production centers; morphology and decoration of these products, considering issues of fabrication chronology; and the methods used in Historical Archaeology for analyzing clay tobacco pipes

Confronting Caribbean Heritage in an Archipelago of Diversity: Politics, Stakeholders, Climate Change, Natural Disasters, Tourism, and Development
The Caribbean archipelago is a series of independent island nations and overseas departments, territories, colonies, or commonwealths of developed countries. About 250 generations of human occupation in the Caribbean have produced a blend of traditions sometimes called a cultural kaleidoscope. Eight thousand years of shifting cultural identities are recorded in archaeological, architectural, documentary, and ecological records, and in memories and oral traditions known as heritagescapes. Caribbean heritagescapes are increasingly threatened by a combination of socioeconomic needs of modern society, ineffective governmental oversight, profit-driven multinational corporations, looters, and natural environmental processes. Balancing the needs of society against the protection and management of heritage requires careful thought and measured dialogue among competing stakeholders. Here we review the status of heritage in the Caribbean and offer a way forward in managing a diminishing supply of heritage resources in the face of current socioeconomic demands, and the unique legislative environments of independent island nations and overseas possessions of developed countries. Keywords: heritagescapes, stakeholders, contested memories, heritage consideration, Caribbean
