This study, conducted at an urban public school, explored the engagements of five, fourth grade, African American students who struggled with reading in school as they participated in critical literacy practices and social action projects with the assumption that critical analysis of written texts and concrete social actions were necessary for student empowerment. Using Discourse Analysis within a microethnographic framework, participants’ responses were analyzed. Early in the study, participants were hesitant to join in critical conversations about race. Over time, as participants deepened their critical literacy engagements, they divulged lived racism both in their private and public worlds. Specifically, the participants described the tensions and transgressions they experienced as minorities from civil rights curriculum, teachers and other students. The findings revealed instead of text based analyses, critical literacy practices transformed into the participants’ critical analysis of racism they experienced in their various worlds (home, school, and the larger, outside world) through language (not text). Similarly, the pre-conceived idea of social action projects changed from the creation of concrete products or actions into discussions in which mainstream discourse was interrupted. Tacit and overt understandings about race, identity and power suggested that the participants assumed multiple and contradictory identities (such as “victim of racism” and “racially prejudiced”) that both empowered and oppressed others in the social action group. Implications for critical literacy practices include that empowering and liberating pedagogy through ‘risky conversations’ is difficult, transitory and radical within the context of school.

Includes bibliographical references / Objective: To describe the characteristics and outcomes of children admitted to PICU following cardiac arrest between January 2010 and December 2011. Methods: Retrospective descriptive study of routinely collected data. Results: Of 2501 PICU admissions, 110 (4.4%; 58.7% male) had preceding cardiac arrest, 80.6% of which occurred in hospital. Median (IQR) age was 7.2 (2.5 - 21.6) months; 30.8% had chronic underlying disease. Children presented most commonly with respiratory (n=28, 27.2%), cardiovascular (n= 22, 21.4%), and gastrointestinal disease (n= 20, 19.4%). Twenty-eight (27.2%) arrested while undergoing a procedure. Cardiopulmonary resuscitation (CPR) was given for median (IQR) 10 (5 - 20) minutes. Thirty-five (34%) patients received no adrenaline, 44 (42.7%) received up to 3 doses of adrenaline, and 24 (23.3%) received more than 3 doses of adrenaline during resuscitation. Duration of CPR and number of adrenaline doses did not significantly influence patient outcome. Survival to PICU discharge was 63 (61.2%), 57 (55.3%) survived to hospital discharge with half the deaths in PICU occurred within 24 hours of PICU admission. Out of 51 survivors whose neurological status were assessed 32 were normal, 6 had mild disability, 7 had moderate disability and 6 had severe disability. Standardized mortality ratio (actual/mean predicted) was 0.7. The median (IQR) length of stay in PICU and hospital were 3 (1 - 8) and 27 (9 -52) days respectively. Pediatric risk of mortality (PIM2) score was the only variable independently associated with mortality on multiple logistic regression (adjusted OR 1.05; 95% CI 1.02 - 1.07; p=0.0009).

Objective- We aimed to describe the use of blood products following cardiac surgery, as well as the outcomes and factors associated with post-operative blood product use Design- Prospective, single centre observational study Setting- Paediatric intensive care unit (PICU) in Cape Town, South Africa Patients- One hundred and twenty-six children <18 years old admitted to the PICU following cardiac surgery between July 2017 and January 2018 Interventions- None Measurements and Main Results- The data was prospectively obtained from blood bank charts, intraoperative and PICU observation charts. Demographic data, intraoperative details and post-operative blood product use were extracted from patient records and entered in a standardised case record form. Fifty three percent of children received blood products following cardiac surgery. The blood products transfused included cryoprecipitate (30.9%), packed red cells (22.2%), albumin (18.3%), fresh frozen plasma FFP (15.9%) and platelet concentrate (15.1%). Low haemoglobin level was commonest indication (86%) for red cell use. Bleeding was the commonest indication for FFP (70%) and cryoprecipitate (67%) use. Thrombocytopenia was the commonest indication (84%) for platelet use while hypotension episodes were predominant (95%) in those who received albumin. The standardized mortality ratio was 3.1 vs 0, respectively, among transfused versus non-transfused patients (p<0.0001). The median (IQR) duration of PICU stay was 5 (3-11) vs 2 (2-5) days, respectively in those transfused versus non-transfused (p<0.0001). The median (IQR) ventilation duration was 47(22-132) hours vs 20 (6-27) hours, respectively among the transfused versus non-transfused (p=<0.0001). The factors associated with blood-product use post cardiac surgery include previous cardiac surgery, younger age, lower weights, and prolonged coagulation parameters (p=<0.05). Conclusion- There is high usage of blood products among children post cardiac surgery. The children transfused had a longer ICU stay, ventilation duration, and higher standardized mortality ratio compared to the non-transfused.

Introduction: Congenital and acquired heart diseases are highly prevalent in developing countries despite limited specialised care. Namibia established a paediatric cardiac service in 2009 with significant human resource and infrastructural constraints. Therefore, patients are referred for cardiac interventions to South Africa. Objectives: To describe the diagnoses, clinical characteristics, interventions, post-operative morbidity and mortality and follow-up of patients referred for care. Methods: Demographics, diagnoses, interventions, intra- and postoperative morbidity and mortality as well as longitudinal follow-up data of all patients referred to South Africa were recorded and analysed. Results: The total cohort constituted 193 patients of which 179 (93%) had congenital and 7% acquired heart disease. The majority of patients (78.8%) travelled more than 400 km to Windhoek prior to transfer. There were 28 percutaneous interventions. Palliative and definitive surgery was performed in 27 and 129 patients respectively. Eighty (80/156, 51.3%) patients had postoperative complications, of which 15 (9.6%) were a direct complication of surgery. Surgical mortality was 8/156 (5.1%, 95% confidence interval 1.2.2-9.8), with a 30- day mortality of 3.2%. Prolonged ICU stay was associated with a 5% increased risk of death (Hazard Ratio 1.05, 95% confidence interval: 1.02-1.08, p=0.001). Follow-up was complete in 151 (78%) patients over seven years. Conclusions: Despite the challenges associated with a cardiac programme referring patients for intervention to a neighbouring country and the adverse characteristics of multiple lesions and complexity associated with late presentation, we report good surgical and interventional outcomes. Our goal remains to develop a comprehensive sustainable cardiac service in Namibia.

Introduction: Hospital acquired infections (HAIs) are an important cause of morbidity and mortality following paediatric cardiac surgery. Aim: To determine the incidence, risk factors for and outcome of postoperative HAIs in the Paediatric Intensive Care Unit (PICU) of the Red Cross War Memorial Children's Hospital (RCWMCH) in Cape Town. Methods: A prospective observational study of all postoperative cardiac patients admitted to PICU from September 2011 to March 2012. The definitions of laboratory confirmed blood stream infections (BSI), urinary tract infections (UTI), and surgical site infections were based on the Centres of Disease Control criteria. Ventilator associated pneumonia (VAP) was diagnosed using a modification of the Clinical Pulmonary Infection Score (CPIS). Results: 110 patients (median age 19 months; 43% male) undergoing 126 surgical procedures were enrolled. Sixty HAIs occurred in 43 (39%) patients (68.3% pulmonary; 13.3% blood; 11.7% wound; 3.3% urine; 3.3% tissue). Nine (8.2%) patients died and their deaths were not related to HAIs.

Contemporary methods of food production in the United States have become undeniably destructive ecologically.  Two of the strongest symbols of that destruction from corporate industrial agriculture are CAFOs (Confined Animal Feeding Operations) and monoculture crop production.  This thesis seeks to find examples of producers refusing these methods as well as what motivates those producers to refuse, and what that refuse could mean politically.  The project is grounded theoretically in the work of critical theorists, especially Herbert Marcuse, because the Frankfurt School\'s criticism of instrumental rationality and understanding of domination functions to elucidate the societal conditions that allow for agricultural (over)production to be swept up in problematic methods in the name of efficiency. Part I starts by analyzing academic as well as popular discourses of CAFOs and the historical process of industrializing meat production and agriculture in the United States.  Here both corporate capitalism and enlightenment rationality are indicted and Marcuse\'s theories are put to work to set up what is being refused. Part II uses examples of organic and local food to provide an understanding for how consumption centered refusals can be co-opted by corporate interest.  Part III seeks out contemporary refusals that go past \'green consumerism\' and foster a "new sensibility" that is grounded in a sense of place, ecological cooperation with nature, and refuses corporatism.  In this new sensibility there is a direct rejection of the instrumental rationality, the profit motive and exploitation of nature. / Master of Public and International Affairs

This study seeks to explicate the intercultural experiences of Puerto Ricans within the diaspora of Central Florida. Specifically, the navigation of communication behaviors among intergroup and outgroup behaviors as Puerto Rican individuals acculturate into the area. This study utilizes communication accommodation theory as its basis to understand integration into a host culture and the impacts on socio-cultural communication behaviors. Findings show the importance of studying diasporic communities as they develop such as that of the Puerto Rican community in Central Florida because it situates the reality of an individual and groups sense of identity in a new cultural context. This research showcases Puerto Rican diasporic individuals struggling with the bilingual brain and acculturating based on their environment. Communication accommodation behaviors are thus deeply rooted in marginalization and negative treatment of diasporic individuals as the "other" in multicultural scenarios. Intercultural self-identity and intersectionality has therefore been impacted by the dynamic between the home culture and host culture.
