New defective models based on the Topp-Leone generated family of distributions
No full textThis paper proposes two new defective models based on the Topp-Leone (TL) gen-erated family of distributions. Unlike most of the cure rate models, the advantage of the defective model is that the cure rate can be modeled without adding any addi-tional parameters to the model. The maximum likelihood function (MLE) is discussed for these models, and the asymptotic property of MLE is verified by simulation. The applications of this method are illustrated by three real data sets
Estimating the Parameters of a Simple Linear Regression Model Without Using Differential Calculus
No full textTo estimate the parameters of a simple linear regression model, students who already know calculus can minimize the total squared deviations by setting its first-order partial derivatives to zero and solving simultaneously. For students who do not know calculus, most teachers/textbooks simply state the formulas without justifying them. Students accept the formulas on faith; and for given data, they evaluate the estimates using a calculator or a statistical software. In this paper, we justify the formulas without invoking calculus. We hope the users of statistics will benefit from our proposed justifications
Shadows and Light: Professional Women Educators Transitioning to Academe
No full textMany professional women educators make the transition from school settings to academe after significant graduate work in their field(s). This transition, which often occurs on a mid- to late-career trajectory, places such individuals within liminal spaces on many levels as they inevitably must navigate unfamiliar, often alien, territory that frequently does not recognize or respect the experiences with which they enter their new university contexts. The collaborative autoethnographic study we embarked upon involved examining our own experiences of making this transition. By revisiting an academic year’s worth of recorded conversations and analyzing them through an ecofeminist lens, we considered the lessons we had learned through engaging in a program renewal process and designing and co-teaching new courses in our first few years as faculty, as well as how these lessons impacted our emerging identities as new teacher educators. Our findings included three broad lessons learned: Beware of Institutionally Invisible Work; This is not High School, Dorothy; and Two Heads and Hearts are One. These lessons taught us to navigate the shadow places (Plumwood, 2008) of academe, including the delegitimization of teaching, nurturing and service work and the dematerialisation (Plumwood, 2008) associated with such delegitimization, and to embrace the light we found rooted in interconnectedness, an ethic of care, and our mutual recognition of the other. Moreover, these lessons offer others in the field ways of understanding the difficult transition to academe undertaken by professional women educators and the complexity of academic/teacher educator identity formation.

Our Language is From the Land: niinyanaan nutr piyii la laange
No full textThis article documents how my cultural identity as a Métis woman is inherently linked to Michif words and phrases that originate from the land. Through the Michif language I continue to situate myself directly on the Saskatchewan prairie landscape. And it is because of the collective efforts of Michif speakers and Métis Old Ones who work tirelessly toward the rejuvenation of Michif language that I have been led toward working within the healing landscape which I now occupy.

Node-ified Ethics: Contesting Codified Ethics as Unethical in ECEC in Ontario
No full textIn this conceptual article, I argue that there is a difference between codified ethics and the ethical. I begin by situating code of ethics in the broader professionalization movement in early childhood education. Drawing upon Gunilla Dahlberg and Peter Moss (2005), I discuss the dematerialization of early childhood educators (ECEs) and the instrumentalization of early childhood education and care (ECEC) in Ontario through the implementation of the Code of Ethics by the College of Early Childhood Education ( 2017). Thinking with Eve Tuck’s (2018) question of “How shall we live?” (p. 157), I take up a critical invitation from Sharon Todd (2003) to consider how codified ethics in education may be rethought “as a relation across difference” (p. 2). I work conceptually with the imagery of nodes from the film Sleep Dealer by Alex Rivera (2008) as an aesthetic device to examine the effect of codified ethics on ECEs. Finally, in conversation with Joanna Zylinska (2014) and Tim Ingold (2011), I re-frame instrumentalized nodes/codes of ethics within the complexity of knots and meshworks to recover the ethical in early childhood education. I offer this piece as a warning that solely relying on codified ethics completes the transformation of the ECE into a worker technician and may be leading us toward a dystopian future and as a call to activism to engage in the complex ethical work required in the small everyday spaces of the early childhood classroom.

Slowing, Desiring, Haunting, Hospicing, and Longing for Change: Thinking With Snails in Canadian Early Childhood Education and Care
No full textThis paper is a collective attempt to respond creatively to a research project we were part of entitled Sketching Narratives of Movement: Towards Comprehensive and Competent Early Childhood Educational Systems Across Canada. We share our slow process of thinking, collaborating, wondering, and pausing along with the figure of the snail as we improvise a nonlinear path towards an unknown future. We think-with various theories of change as a response to narratives shared by participants in the project’s knowledge mobilization events: two public webinars and the production of a series of short video interviews. The pandemic simultaneously (re)inscribed ECEC with familiar discourses and narratives, yet, it also issued forth the potential for new imaginaries. ECEC was suddenly positioned as a critical community life-sustaining space for entire systems stressed by a pandemic. Amidst the attention, however, “slimy” traces of chronic neglect, underfunding, and undervaluing of ECEC were gleaming. Given the unpredictable momentum, we argue that it is essential that we open up ECEC to different narratives of movement. To this end, we offer five theoretical capsules titled: Slowing, Desiring, Haunting, Hospicing, and Longing as provocations for storying care otherwise and for stirring ethical consideration with potentialities for slow activism in ECEC.

The Exponentiated Half Logistic-Generalized G Power Series Class of Distributions: Properties and Applications
No full textA new generalized class of distributions called the Exponentiated Half Logistic-Generalized G Power Series (EHL-GGPS) distribution is proposed. We present some special cases in the proposed distribution. Several mathematical properties of the EHL-GGPS distribution were also derived including order statistics, moments and maximum likelihood estimates. A simulation study for selected parameter values is presented to examine the consistency of the maximum likelihood estimates. Finally, some real data applications of the EHL-GGPS distribution are presented to illustrate the usefulness of the proposed class of distributions
The Gompertz-Topp Leone-G Family of Distributions with Applications
No full textWe introduce a new family of distributions, referred to as the Gompertz-Topp-Leone-G (Gom-TL-G) distribution. The new family of distributions can be expressed as an infinite linear combination of the Exp-G distributions. It can handle extremely tailed data and has both monotonic and non-monotonic hazard rate functions. A simulation study is used to assess the estimation method. Some real data examples are analyzed for illustrative purposes
Asônimâkêwin: Passing on What We Know
No full textThis paper will explore the history and present-day land use, and the islands and rivers located around Île à la Crosse, Saskatchewan. I will share how storytelling and spiritual ecology have always connected the people of Île à la Crosse to these landscapes and waterways. The knowledges that have been passed on to me through oral storytelling and research have been written in this paper. Learning these stories and histories shapes our identity as Indigenous peoples.
