Implicit and explicit pedagogical practices related to sociocultural issues and social justice in physical education teacher education programs

Background: For many years, scholars in PETE have argued for the importance of educating pre-service teachers (PSTs) about equality (e.g., Evans 1990), sociocultural perspectives and issues (e.g., Cliff, Wright and Clarke, 2009; Author 2014) and critical pedagogy (e.g., Fernandez-Balboa 1997; Philpot 2015). Despite this advocacy, we would argue that there are significant differences in how faculty teach about sociocultural issues, and for, social justice. The pedagogical actions through which Physical Education Teacher Educators (PETEs) do this work is the focus of this paper. Purpose: We investigated the pedagogical approaches and strategies used by PETE faculty to address and educate PSTs about social justice and sociocultural issues related to gender, race, sexuality, (dis)ability, socioeconomic status and religion in their individual PETE programs. In this study, we draw on transformational pedagogy (Ukpokodu 2009; Ovens 2017) as a framework for theorizing the data. Through this study, we highlight the pedagogical practices espoused as those that engender transformative learning. Data collection and analysis: Data for this interpretive qualitative research study was collected primarily through in-depth semi-structured interviews with over 70 PETEs who work in 48 PETE programs across Australia, Canada, England, Ireland New Zealand, Sweden, and the United States. Furthermore, an informational survey was used to gather demographic data of the participants. The participants, all current PETEs, had a wide range of professional experiences, which included the length of time in the profession, the type of institution employed, educational backgrounds and courses taught. Data analysis was completed using the processes of content analysis and the constant comparative method (Corbin and Strauss 2008). Findings: Three major themes represent the findings. In the first theme, ‘Intentional and Explicit Pedagogies’ we provide descriptions of the approaches and strategies used by PETEs in this study that were planned in advance of the learning experiences. In the second theme, ‘Teachable Moments’ we provide examples of how PETEs utilized ‘teachable moments’ in implicit and explicit ways to educate PSTs about sociocultural issues. The third theme, ‘Resistance and Constraints’ captures the individual challenges PETE faculty faced within their courses if, and when, they teach for equity and social justice. The findings suggest that social justice struggles to find an explicit presence within many PETE programs and that educating PSTs about sociocultural issues and social justice is lacking in many PETE programs

Vasodilator factors in the systemic and local adaptations to pregnancy

We postulate that an orchestrated network composed of various vasodilatory systems participates in the systemic and local hemodynamic adaptations in pregnancy. The temporal patterns of increase in the circulating and urinary levels of five vasodilator factors/systems, prostacyclin, nitric oxide, kallikrein, angiotensin-(1–7) and VEGF, in normal pregnant women and animals, as well as the changes observed in preeclamptic pregnancies support their functional role in maintaining normotension by opposing the vasoconstrictor systems. In addition, the expression of these vasodilators in the different trophoblastic subtypes in various species supports their role in the transformation of the uterine arteries. Moreover, their expression in the fetal endothelium and in the syncytiotrophoblast in humans, rats and guinea-pigs, favour their participation in maintaining the uteroplacental circulation. The findings that sustain the functional associations of the various vasodilators, and their participation by endocrine, paracrine and autocrine regulation of the systemic and local vasoactive changes of pregnancy are abundant and compelling. However, further elucidation of the role of the various players is hampered by methodological problems. Among these difficulties is the complexity of the interactions between the different factors, the likelihood that experimental alterations induced in one system may be compensated by the other players of the network, and the possibility that data obtained by manipulating single factors in vitro or in animal studies may be difficult to translate to the human. In addition, the impossibility of sampling the uteroplacental interface along normal pregnancy precludes obtaining longitudinal profiles of the various players. Nevertheless, the possibility of improving maternal blood pressure regulation, trophoblast invasion and uteroplacental flow by enhancing vasodilation (e.g. L-arginine, NO donors, VEGF transfection) deserves unravelling the intricate association of vasoactive factors and the systemic and local adaptations to pregnancy

Study of Women, Infant feeding, and Type 2 diabetes mellitus after GDM pregnancy (SWIFT), a prospective cohort study: methodology and design

<p>Abstract</p> <p>Background</p> <p>Women with history of gestational diabetes mellitus (GDM) are at higher risk of developing type 2 diabetes within 5 years after delivery. Evidence that lactation duration influences incident type 2 diabetes after GDM pregnancy is based on one retrospective study reporting a null association. The Study of Women, Infant Feeding and Type 2 Diabetes after GDM pregnancy (SWIFT) is a prospective cohort study of postpartum women with recent GDM within the Kaiser Permanente Northern California (KPNC) integrated health care system. The primary goal of SWIFT is to assess whether prolonged, intensive lactation as compared to formula feeding reduces the 2-year incidence of type 2 diabetes mellitus among women with GDM. The study also examines whether lactation intensity and duration have persistent favorable effects on blood glucose, insulin resistance, and adiposity during the 2-year postpartum period. This report describes the design and methods implemented for this study to obtain the clinical, biochemical, anthropometric, and behavioral measurements during the recruitment and follow-up phases.</p> <p>Methods</p> <p>SWIFT is a prospective, observational cohort study enrolling and following over 1, 000 postpartum women diagnosed with GDM during pregnancy within KPNC. The study enrolled women at 6-9 weeks postpartum (baseline) who had been diagnosed by standard GDM criteria, aged 20-45 years, delivered a singleton, term (greater than or equal to 35 weeks gestation) live birth, were not using medications affecting glucose tolerance, and not planning another pregnancy or moving out of the area within the next 2 years. Participants who are free of type 2 diabetes and other serious medical conditions at baseline are screened for type 2 diabetes annually within the first 2 years after delivery. Recruitment began in September 2008 and ends in December 2011. Data are being collected through pregnancy and early postpartum telephone interviews, self-administered monthly mailed questionnaires (3-11 months postpartum), a telephone interview at 6 months, and annual in-person examinations at which a 75 g 2-hour OGTT is conducted, anthropometric measurements are obtained, and self- and interviewer-administered questionnaires are completed.</p> <p>Discussion</p> <p>This is the first, large prospective, community-based study involving a racially and ethnically diverse cohort of women with recent GDM that rigorously assesses lactation intensity and duration and examines their relationship to incident type 2 diabetes while accounting for numerous potential confounders not assessed previously.</p

Observations on the Vitality of the Newborn

Vitality, defined in the dictionary as &apos; the capacity to thrive and endure, &apos; is a summation of all assimilative, metabolic, circulatory, and protective functions. It can be measured crudely, in large groups, by mortality and morbidity rates, but since such rates are determined by the reaction between groups of individuals and a variable environment, they may be difficult to interpret. Some observers (Stuart, 1945) used measures such as size at birth or degree of osseous development in an attempt to demonstrate differences of quality in infants, but size and stage of development are not necessarily correlated with efficiency of function. Baird (1949) has posed the question, &apos; How does one tell whether a particular baby is more vital than another? &apos; Some measure is necessary if we are to correlate vitality with the mother&apos;s health and diet during pregnancy. Some idea may be obtained by noting the presence or absence of foetal distress during labour and the child&apos;s behaviour after birth. The vigour of its movements is difficult to measure, and its ability to suck depends on the type of breast and nipples, the milk supply, and the efficiency of the mother and nurse. General clinical assessment of vitality is highly subjective and hence has limited scientific value. It was considered that objective assessment of the more accessible neonatal reflexes might be useful. The interpretation of tests carried out during the first week of life should not be unduly complicated by the influence of the general extra-uterine environment. This paper deals with the sucking reflex, the grasp reflex, muscular power, and power of coordinating upper limb action. The first of these is bound up with ability to obtain nourishment and the others are probably associated with the ability of a baby to protect itself. Performance on test, therefore, should have some relationship to the &apos; capacity to thrive and endure.&apos; Initial studies were made of 100 unselected normal * Walter and Eliza Hall travelling research fellow. infants, followed by studies of 80 normal offspring of primiparae. A &apos;normal &apos; infant was defined as one weighing more than 51 lb. at birth, without any obvious physical abnormality, and requiring no more than routine care in the lying-in wards of a maternity hospital
