P.R.I.D.E.: Positive Racial Identity Development In Early Education, Aisha White, Shannon B. Wanless Dec 2019

P.R.I.D.E.: Positive Racial Identity Development In Early Education, Aisha White, Shannon B. Wanless

Journal of Curriculum, Teaching, Learning and Leadership in Education

Racism negatively affects children of color in the United States, particularly Black children. Theirs is a history of marginalization since the slavery era, and the impacts are cognitive, social, and psychological. Additionally, Black children face unique challenges upon entering formal education, resulting in disturbing academic outcomes. Yet, adults can facilitate Black children’s development of positive racial identity to help them handle the negative implications of experiencing racism across their lifespan. A description of the research related to positive racial identity is provided along with presentation of the P.R.I.D.E. program, a Pittsburgh-based effort that is designed to help adults build the …

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 …

The Italian Catalogue Of Herbage Varieties, M. Giolo, Giovanni Corsi, N. Mugueta, F. Sorgoni, Pier Giacomo Bianchi, Renzo Torricelli, Mario Falcinelli

IGC Proceedings (1977-2023)

With 3.4 million hectares, permanent grassland covers 25.8% of Italian U.A.A. (Usable Agricultural Area). Most of this is located in hilly and mountainous areas and is important for the stability of the soil even if their productivity is low. Alfalfa and annual forages cover 1.8 million hectares (C.R.P.A. 2010). Italy’s large longitudinal extension (between latitudes 35° and 47° N), delivers a great variety of climates (Fig. 1). The northern regions bordering the rest of Europe differ greatly from the southern regions surrounded by the Mediterranean Sea.

Criteria For The Registration Of Medicago Polymorpha L. And Lolium Rigidum Gaud. Varieties In A Voluntary Register In Italy, Luciano Pecetti, Giovanni Corsi, Federico Sòrgoni, Pier Giacomo Bianchi, Mario Falcinelli, Renzo Torricelli Dec 2019

Criteria For The Registration Of Medicago Polymorpha L. And Lolium Rigidum Gaud. Varieties In A Voluntary Register In Italy, Luciano Pecetti, Giovanni Corsi, Federico Sòrgoni, Pier Giacomo Bianchi, Mario Falcinelli, Renzo Torricelli

IGC Proceedings (1977-2023)

Extensive and semi-extensive livestock systems in Southern Europe rely largely on permanent pastures, the productivity of which could be improved by sowing adapted species. Native forage species are a valuable tool for Mediterranean livestock production, owing to their specific adaptation to the harsh environment (featuring prolonged and severe spring-summer drought) and their generally good tolerance to grazing. Annual, self-reseeding species are able to cope with the prevailing drought stress by terminating the vegetative phase and setting seed before the onset of the stressful period, and enhance the durability of the sward by their self-reseeding capacity and subsequent seedling regeneration. Subterranean …

Trinexapac-Ethyl Application Increased Seed Yield Of Diploid Red Clover (Trifolium Pratense L.), Dave Monks Dec 2019

Trinexapac-Ethyl Application Increased Seed Yield Of Diploid Red Clover (Trifolium Pratense L.), Dave Monks

IGC Proceedings (1977-2023)

Red clover (Trifolium pratense L.) is a perennial legume grown for forage that, when grown with a seed yield focus in New Zealand, averages 260 kg seed/ha (Clifford, 1979). One way to shift the production focus from biomass to seed yield is the use of plant growth regulators (PGRs). Prior work with PGRs in legume seed production has centred on the gibberellin biosynthesis inhibitors paclobutrazol, uniconazol and cycocel that aim to increase the harvest index of a crop by reducing the ratio of vegetative to reproductive biomass. Inhibiting gibberellin synthesis decreases cell division and cell enlargement; reducing the length …

Effect Of Gamma Irradiation On Seed Germination Traits Of Bromus Inermis, Ghasem Ali Dianati Tilaki, Arezu Alizadeh, Behnam Naserian Khiabani Dec 2019

Effect Of Gamma Irradiation On Seed Germination Traits Of Bromus Inermis, Ghasem Ali Dianati Tilaki, Arezu Alizadeh, Behnam Naserian Khiabani

IGC Proceedings (1977-2023)

Ionizing radiation technology and in particular gamma radiation is developing as a useful treatment in crop production. Gamma rays cause different physiological and morphological responses in cells and tissues that appear as an increase in germination speed, germination capacity and growth of the leaves (Amjad and Anjum 2007). Several reports on the stimulatory affects on plant growth when exposed to irradiation techniques with radioactive rays at low doses are available (Charbaji and Nabulsi 1999; Moussa 2006). Seed treatment with low doses of gamma rays resulted in a significant increase in germination traits, plant vigor and yield attributes of wheat (Melki …

Advances In Nutrient Management Of Grass Seed Crops, René Gislum, Birte Boelt Dec 2019

Advances In Nutrient Management Of Grass Seed Crops, René Gislum, Birte Boelt

IGC Proceedings (1977-2023)

Nutrient management of herbage grass seed crops is just as complex as for other agricultural crops when the aim is to optimise economic net return and minimise environmental impact. The use of economic optimum nitrogen (N) application rate (ECO-N) defined as the N application rate that maximise net return for the seed grower is an easy and applicable method for seed growers. Besides the economic advantages of implementing ECO-N there is an additional positive environmental effect as ECO-N is lower than the N rate that maximises seed yield and a lower N application rate will concomitantly lower the potential risk …

Effects Of Storage Conditions On Endophyte And Seed Viability In Pasture Grasses, David E. Hume, Stuart D. Card, M. Philip Rolston Dec 2019

Effects Of Storage Conditions On Endophyte And Seed Viability In Pasture Grasses, David E. Hume, Stuart D. Card, M. Philip Rolston

IGC Proceedings (1977-2023)

Several important temperate pasture grasses have co-evolved with mutualistic Epichloë fungal endophytes. These endophytes impart beneficial attributes to their host as they enhance the fitness of the grass when under biotic and abiotic stresses. The asexual species of these fungi (formerly classed as Neotyphodium) are obligate symbionts, and efficiently colonise newly formed tillers and infect seed by direct colonisation of the embryo. These endophytes are strictly seed transmitted. Survival of the fungus in this seed is therefore critical for the dissemination of endophyte-infected seed to grassland farmers. Longevity of endophyte in stored seed is primarily determined by the length …

Managing Seed Dormancy In Forage Legumes And Grasses: An Update, Yanrong Wang, Xiaowen Hu Dec 2019

Managing Seed Dormancy In Forage Legumes And Grasses: An Update, Yanrong Wang, Xiaowen Hu

IGC Proceedings (1977-2023)

Seed dormancy is a common feature of the majority of forage species. It usually causes problems both to the grower and the seed analyst. Many methods have been developed to break dormant seed over the time, and efficacy of a method usually varies with species and cultivars. The objective of this paper is to review and summarise important methods used for seed dormancy breaking in forage legume and grass species, and the mechanisms involved.

Restoring North America’S Sagebrush Steppe Ecosystem Using Seed Enhancement Technologies, Matthew D. Madsen, Kirk W. Davies, Chad S. Boyd, Jay D. Kerby, Daniel L. Carter, Tony J. Svejcar Dec 2019

Restoring North America’S Sagebrush Steppe Ecosystem Using Seed Enhancement Technologies, Matthew D. Madsen, Kirk W. Davies, Chad S. Boyd, Jay D. Kerby, Daniel L. Carter, Tony J. Svejcar

IGC Proceedings (1977-2023)

Rangelands occupy over a third of global land area, and in many cases are in less than optimum condition as a result of past land use, catastrophic wildfire and other disturbance, invasive species, or climate change. Often the only means of restoring these lands involves seeding desirable species, yet there are few cost effective seeding technologies, especially for the more arid rangeland types. The inability to consistently establish desired plants from seed may indicate that the seeding technologies being used are not successful in addressing the primary sources of mortality in the progression from seed to established plant. Seed enhancement …

Comprehensive Evaluation Of Wild Elymus L. Germplasm In Inner Mongolia, Juan Qi, Wen-Xia Cao, Ting Jiao, Xiao-Peng Pu, Wei-Hong Yan

IGC Proceedings (1977-2023)

Grassland degradation is increasing in severity and is an important global issue in the 21st century. Increasing research is being conducted on how to solve these problems (Niu and Jiang 2004). Restoration and revegetation of degraded grassland and the establishment of artificial pastures are important in addressing degradation. Successful restoration requires the identification of species and seed sources that are adapted to the ecological conditions of the restoration site. Elymus L. is a large genus that contains about 150 species distributed across a wide range of ecological sites across temperate and subtropical regions of the world (Dewey 1984; Love 1984). …

IGC Proceedings (1977-2023)

γ-Linolenic acid (GLA, 18:3Δ6, 9, 12) and octadecatetraenoic acid (OTA, 18:4Δ6, 9, 12, 15) are important polyunsaturated fatty acids (PUFAs), which have been proved to be benefit for human health (Fan and Chapkin 1998; Whelan 2009). Currently, fish are the predominant source of PUFAs. However, with the growth of world’s population and the more nutrition requirements, fishery resources are shrinking. Alternative sources of PUFAs are being investigated (Truksa et al. 2009). The major oil crops do not contain GLA and OTA, only several plant species contain these important fatty acids in their leaf lipids and …
