Clostridium Difficile In Asia: Opportunities For One Health Management, Deirdre A. Collins, Thomas V. Riley Dec 2019

Clostridium Difficile In Asia: Opportunities For One Health Management, Deirdre A. Collins, Thomas V. Riley

Research outputs 2014 to 2021

Clostridium difficile is a ubiquitous spore-forming bacterium which causes toxin-mediated diarrhoea and colitis in people whose gut microflora has been depleted by antimicrobial use, so it is a predominantly healthcare-associated disease. However, there are many One Health implications to C. difficile, given high colonisation rates in food production animals, contamination of outdoor environments by use of contaminated animal manure, increasing incidence of community-associated C. difficile infection (CDI), and demonstration of clonal groups of C. difficile shared between human clinical cases and food animals. In Asia, the epidemiology of CDI is not well understood given poor testing practices in many countries. …

Developing A Vocabulary To Talk About Race In The White Home: One Family’S Experience, Rhianna K. Thomas Dec 2019

Developing A Vocabulary To Talk About Race In The White Home: One Family’S Experience, Rhianna K. Thomas

Journal of Curriculum, Teaching, Learning and Leadership in Education

Studies have shown white parents actively avoid talking about race as the primary method of racial socialization of their white children (Bartoli et al., 2016; Pahlke, Bigler, & Suizzo, 2012). This limits children’s ability to talk about and therefore think about race in nuanced ways, resulting in white children who consider their own race meaningless and do not identify racially (Bartoli et al., 2016). Antiracist education breaks these white discourse norms, and directly addresses systemic racism (Escayg, 2018). This paper describes how one white family attempted to enact antiracist education in the home with a focus on developing a shared …

Supporting Conversations About Race And Racism With Young Children While Watching For Manifestations Of Whiteness, Shubhi Sachdeva, Jennifer Adair

Journal of Curriculum, Teaching, Learning and Leadership in Education

This article examines two first grade classrooms in Central Texas that routinely have conversations about racial justice. In both classrooms we studied, children participated in racial conversations in large group structured discussions with the teacher and in less formal peer conversations away from the teachers. We follow both classrooms and detail the ways in which the teachers supported conversations about race, racism and racial violence with and among the young children in their classes. We highlight specific strategies and mechanisms that both teachers used to open up their classrooms for social and racial justice conversations. Then, we show how even …

Troubling ‘Race’ And Discourses Of Difference And Identity In Early Childhood Education In South Africa, Jaclyn Murray Dec 2019

Troubling ‘Race’ And Discourses Of Difference And Identity In Early Childhood Education In South Africa, Jaclyn Murray

Journal of Curriculum, Teaching, Learning and Leadership in Education

This article emerges from a broader ethnographic study exploring how young children aged five and six years, and their educators, construct ‘race’ identities in a culturally diverse early childhood education setting in post-apartheid South Africa. Historically, systems of educational inequality and injustice have had a profound impact on how subjects have come to be ‘raced’ in the South African context. Drawing on a poststructural framework that problematizes the notion of identity, ‘race’, and young children’s discursive understandings of ‘race’, this article traces the complex ways in which young children and educators (re)construct, negotiate, resist and subvert subject formation processes in …

“They Need To Say Sorry:” Anti-Racism In First Graders’ Racial Learning, Anna Falkner Dec 2019

“They Need To Say Sorry:” Anti-Racism In First Graders’ Racial Learning, Anna Falkner

Journal of Curriculum, Teaching, Learning and Leadership in Education

Young children of color in the United States are experiencing the material effects of racism on a daily basis. There have been arguments for anti-bias and anti-racist education across the field of education, yet most recommendations are based on older students or studies in laboratory settings. In this critical ethnography, the author examined the wide variety of strategies one class of first graders used to learn about race and of the socio-political and racial climate in which they live. In this paper, the author argues that children carefully consider racial conditions in society and imagine anti-racist praxis as part of …

Promoting A Positive Racial Identity In Young African Caribbean Children: An Anti-Colonial Approach, Kerry-Ann Escayg, Zoyah Kinkead-Clark Dec 2019

Promoting A Positive Racial Identity In Young African Caribbean Children: An Anti-Colonial Approach, Kerry-Ann Escayg, Zoyah Kinkead-Clark

Journal of Curriculum, Teaching, Learning and Leadership in Education

Most empirical contributions on children and race, and the theories derived from this body of work, have focused on American or Canadian children. Some scholars have begun to explore children’s attitudes about race in international contexts, but few have investigated racial identity and attitudes among African Caribbean children in the English-speaking Caribbean context. In this article, we first review international scholarship on children and race, as well as research involving Caribbean children and race. Next, we use an anti-colonial perspective to explore specific pedagogical strategies that can support positive racial identities among young African Caribbean children in the region.

But, I Don’T Believe It’S About Race’: Challenging Fallacies Of Race And Racism Amongst Early Childhood Educators In Ontario, Beverly-Jean J. Daniel, Kerry-Ann Escayg Dec 2019

But, I Don’T Believe It’S About Race’: Challenging Fallacies Of Race And Racism Amongst Early Childhood Educators In Ontario, Beverly-Jean J. Daniel, Kerry-Ann Escayg

Journal of Curriculum, Teaching, Learning and Leadership in Education

There is the continued belief that children do not see race and that they are racially innocent. This belief is evidenced in early childhood environments and influences the practices of the instructors in these settings. However, research continues to show that children do see and react to varying markers of race. This research project focused on early childhood educators’ interpretations of children’s racially coded behaviours and interactions. The results revealed four central themes: racial evasiveness; racial dis-ease; parental role in promoting racism; and limited educational preparation. This study contributes to the growing body of research on children, race, and early …

Politicizing Early Childhood Education And Care In Ontario: Race, Identity And Belonging, Zuhra E. Abawi, Rachel Berman Dr. Dec 2019

Politicizing Early Childhood Education And Care In Ontario: Race, Identity And Belonging, Zuhra E. Abawi, Rachel Berman Dr.

Journal of Curriculum, Teaching, Learning and Leadership in Education

The Early Childhood Education and Care (ECEC) landscape, much like the K-12 education system in Ontario, is largely encompassed by bias-free, neutral and colourblind narratives of identity and social location (Author 1, 2018). These discursive practices portray young children and early learning settings as raceless and equal spaces that engage children in interactions and discussions of race and identity are inappropriate. Education in Ontario and Canada as an entity is marked by myth of the Canadian nation-state (Thobani, 2007) through celebratory, themed, recognition-based initiatives that mark differences, while leaving the status quo of whiteness unchallenged and intact (DiAngelo, 2018). The …

Characterization Of The Semi-Permeable Layer In Seed Of Elymus Nutans, Jing Zhou, Yanrong Wang, Xueqing He Dec 2019

Characterization Of The Semi-Permeable Layer In Seed Of Elymus Nutans, Jing Zhou, Yanrong Wang, Xueqing He

IGC Proceedings (1977-2023)

A semi-permeable layer of the seed coat exists in many species which allows controlled water uptake and gas ex-change, while preventing solute transport (Beresniewicz et al. 1995). This layer could act as a barrier to apoplastic permeability and radicle emergence (Salanenka et al. 2009). It could also restrict the tetrazolium viability test and the electrical conductivity vigour test applied to evaluate seed quality (Yan and Wang 2008; Zhou and Wang 2012). An earlier study reported that semi-permeable layers exist in grass species, but recently research has shown that the layer was not found in seeds of oat (He …

White Clover Seed Production Response To Irrigation, Ana L. Pereira, Ariel Pimienta, Pamela Aguirre, Marita Ferriso, Virginia Pravia Dec 2019

White Clover Seed Production Response To Irrigation, Ana L. Pereira, Ariel Pimienta, Pamela Aguirre, Marita Ferriso, Virginia Pravia

IGC Proceedings (1977-2023)

White clover is more sensitive to soil water restriction compared to other perennial legumes, due to its shallow root system and poor stomatal control. Its undetermined growth is influenced by soil water content and seed production is reduced when vegetative growth is not restricted through irrigation management. Restricting the amount of soil available water during the bloom stage reduced plant vegetative growth and increases seed production (Clifford, 1986). In Uruguay, there is not a defined rainy season, and annual average ranges between 1100 and 1300mm. However, due to higher water demand during late spring and summer, a water deficit period …

Does Scarification Time Affect Hydrotime Model Parameters Of Vicia Angustifolia Seed Germination?, Xiaowen Hu, Tingshan Li, Yanrong Wang

IGC Proceedings (1977-2023)

Hard seed, also classified as physical dormancy, is very common in forage legumes (Baskin and Baskin 2004). Many methods, based on scarifying seed coat have been developed such as mechanical scarification, chemical scarification to soft hard seed (Baskin and Baskin 1998). Hydrotime is a way to describe the relationship between water potential (Ψ) and seed germination rates and percentages (Bradford 1990) The hydrotime model has proven to be useful for understanding the physiological mechanism of seed germination and has been suggested as a tool to describe seed germination time in relation to water condition (Alvarado and Bradford 2002). …
