In the Name of the Father and the Mother: Mourning, Memory and Imagination in the Poetry of José Kozer, Tamara Kamenszain, and Eduardo Espina
While often taken as sentimental in nature, poetry about death provides poets and readers an artistic space for processing grief. The Latin American Neobaroque, a way of writing poetry know predominantly for its intellectual approach to language, has to date provided no understanding of an emotional component as a feature of its creative conception. The manner in which the formally recognized Neobaroque poets, José Kozer, Tamara Kamenszain, and Eduardo Espina avoid sentimentality in new poems written on the deaths of their parents is a question on which preliminary research shows little to no exchange of ideas. For this reason, it is suggested that these three poets create a caesura within the understanding of the discourse on the Neobaroque. In so doing, this investigation becomes essential as the first serious line of inquiry with significant intellectual value on this subject, and is advanced through the creation of a framework for anti-sentimentality in the Neobaroque. As a result of this investigation, it is ascertained that the concept of poetic areté provides a much-needed response to this and other questions regarding “how” these poets, and possible others as well, filter their emotions through the intellect, and is the foundation for this study
Overweight, physical activity and high blood pressure in children: a review of the literature
Obesity is a growing problem in developed countries and is likely a major cause of the increased prevalence of high blood pressure in children. The aim of this review is to provide clinicians and clinical scientists with an overview of the current state of the literature describing the negative influence of obesity on blood pressure and it’s determinants in children. In short, we discuss the array of vascular abnormalities seen in overweight children and adolescents, including endothelial dysfunction, arterial stiffening and insulin resistance. We also discuss the potential role of an increased activation of the sympathetic nervous system in the development of high blood pressure and vascular dysfunction associated with obesity. As there is little consensus regarding the methods to prevent or treat high blood pressure in children, we also provide a summary of the evidence supporting relationship between physical activity and blood pressure in children and adolescents. After reviewing a number of physical activity intervention studies performed in children, it appears as though 40 minutes of moderate to vigorous aerobic-based physical activity 3–5 days/week is required to improve vascular function and reduce blood pressure in obese children. Future studies should focus on describing the influence of physical activity on blood pressure control in overweight children
Life Lessons from the Landscape: Spatial Education for Earthquake Preparedness
Architecture can be conceived and designed as an active participant in enhancing awareness of the prevalence
of seismic activity by illuminating the unremitting transformation of the landscape and providing places
where interaction is focussed around seismic issues. The continued awareness of changes to our landscape,
potential loss of life, property, and national cultural or historical artefacts is an important means by which
future preparedness can be encouraged. This thesis argues that an awareness of the message to safeguard
one's future and one's family's futures could be understood through a spatial experience.
This thesis proposes an architectural approach for seismically active contexts using a specific site – a
recreational reserve called Harcourt Park in Upper Hutt – as a design research case study. The site is of great
geological significance to the Wellington region and New Zealand as its natural landmarks can be used to
measure and publicly witness the direct effects of seismic movement along the Wellington Fault line which
runs through the centre of the site. The thesis uses architecture to transform the site into a living memorial,
which recognises the past devastating earthquakes in New Zealand and provides for the commemoration
of losses from future damaging earthquakes should public preparedness not improve. The architecture
also functions as an earthquake education facility and geologist research facility in order to enhance the
educational experience of the site. The intention of the thesis is to use architecture as a means of actively
enhancing public awareness of the need to understand and prepare for the effects of seismic activity

Excessive Entry, Investment and Congestion Cost in the Electricity Industry
Electricity is a large and crucial US industry, with annual sales and investment of 80 billion respectively. Two important topics in the industry, over the past 25 years, are the restructuring of state markets and variation electricity demand. Both changes occurred during the largest increase in electricity capacity in US history, the “Gas Boom,” which increased generating capacity by over 33 percent. This thesis links these topics with the increase in gas capacity and estimates their effect on electricity industry investment and prices.Chapter 1 estimates the effect of restructuring on US power plant investment, finding states that took steps toward retail competition built, on average, 593 MW more gas-fired CCGT power plants than if regulation had remained in place. Evidence of oversupply, bankruptcies, and falling capacity factors suggests this entry was excessive. Chapter 2 investigates the cause and cost of this excessive entry, finding it consistent with contagion, manager overconfidence, and falling long- term interest rates. The welfare cost is estimated to be $10.8 billion. Chapter 3 provides a first estimate of the impact of demand variance on electricity prices, finding an increase of 10 percent in demand variance leads to an increase of 9.7 percent in average state electricity prices. This impact was found to be significant across all three sectors of electricity use. These findings inform policymaker decisions in the future, suggesting states concern themselves with the lower and upper bound of capacity investment, while encouraging more measures to reduce daily and seasonal demand variation
Left ventricular systolic performance during prolonged strenuous exercise in female triathletes
BACKGROUND: The effect of prolonged strenuous exercise (PSE) on left ventricular (LV) systolic function has not been well studied in younger female triathletes. This study examined LV systolic function prior to, during and immediately following PSE (i.e., 40 km bicycle time trial followed by a 10 km run) in 13 younger (29 ± 6 years) female triathletes. METHODS: Two-dimensional echocardiographic images were obtained prior to, at 30-minute intervals during and immediately following PSE. Heart rate, systolic blood pressure, end-diastolic and end-systolic cavity areas were measured at each time point. Echocardiographic and hemodynamic measures were also combined to obtain LV end-systolic wall stress and myocardial contractility (i.e., systolic blood pressure – end-systolic cavity area relation). RESULTS: Subjects exercised at an intensity equivalent to 90 ± 3% of maximal heart rate. Heart rate, systolic blood pressure, systolic blood pressure – end-systolic cavity area relation and fractional area change increased while end-diastolic and end-systolic cavity areas decreased during exertion. CONCLUSIONS: PSE is associated with enhanced LV systolic function secondary to an increase in myocardial contractility in younger female triathletes
Trajectories of Objectively Measured Physical Activity among Secondary Students in Canada in the Context of a Province-Wide Physical Education Policy: A Longitudinal Analysis
Lower levels of physical activity are associated with childhood obesity. School physical education (PE) policies have been identified as critical to improve child and adolescent physical activity levels but there has been little evaluation of such policies. In the province of Manitoba, Canada, the government implemented a mandatory PE policy in secondary schools designed to increase the daily physical activity levels of adolescents. The objective of this study was to examine the longitudinal changes in and the factors associated with the physical activity trajectories of adolescents in Manitoba during their tenure as secondary school students in the context of this school PE policy. The results found, despite the PE policy, a grade-related decline in the physical activity trajectories of adolescents; however, the decline in physical activity was attenuated among adolescents with low and moderate baseline physical activity compared to adolescents with high baseline physical activity and among adolescents who attended schools in neighbourhoods of low compared to high socioeconomic status. There are several possible explanations for these findings, including the influence of the PE policy on the PA patterns of adolescent subpopulations that tend to be at higher risk for inactivity in both childhood and adult life
“How we do it”: A qualitative study of strategies for adopting an exercise routine while living with type 1 diabetes
IntroductionFor people living with type 1 diabetes (T1D) the challenge of increasing daily physical activity (PA) is compounded by the increased risks of hypoglycemia and glucose variability. Little information exists on the lived experience of overcoming these barriers and adopting and maintaining an active lifestyle while living with T1D.Research Design and MethodsWe conducted a patient-led qualitative study consisting of semi-structured interviews or focus groups with 22 individuals at least 16 years old living with T1D. We used existing patient co-researcher networks and snowball sampling to obtain a sample of individuals who reported being regularly physically active and had been diagnosed with T1D for at least one year. We used an interpretive description analysis to generate themes and strategies associated with maintaining an active lifestyle while living with T1D. We involved patient co-researchers in study design, data collection, and interpretation.Results14 self-identified women and 8 self-identified men (ages 19-62, median age 32 years) completed the study, led by either a researcher, or a patient co-researcher and research assistant regarding their strategies for maintaining an active lifestyle. We identified five themes that facilitate regular sustained PA: (1) Structure and organization are important to adopt safe PA in daily life “I can’t do spontaneous exercise. I actually need a couple hours of warning minimum”; (2) Trial and error to learn how their body responds to PA and food “Once you put the time and effort into learning, you will have greater success”; (3) Psychosocial aspects of PA “…because it’s not just your body, it’s your soul, it’s your mind that exercise is for”; (4) Diabetes technology and (5) Education and peer support. Strategies to overcome barriers included (1) Technology; (2) Integrating psychosocial facilitators; (3) Insulin and carbohydrate adjustments; and (4) Planning for exercise.ConclusionsLiving an active lifestyle with T1D is facilitated by dedicated structure and organization of routines, accepting the need for trial and error to understand the personalized glycemic responses to PA and careful use of food to prevent hypoglycemia. These themes could inform clinical practice guidelines or future trials that include PA interventions
Mitral annular myocardial velocity assessment of segmental left ventricular diastolic function after prolonged exercise in humans
This article has been made available through the Brunel Open Access Publishing Fund and is available from the specified link - Copyright @ 2005 The Physiological society.We assessed segmental and global left ventricular (LV) diastolic function via tissue-Doppler imaging (TDI) as well as Doppler flow variables before and after a marathon race to extend our knowledge of exercise-induced changes in cardiac function. Twenty-nine subjects (age 18–62 year) volunteered to participate and were assessed pre- and post-race. Measurements of longitudinal plane TDI myocardial diastolic velocities at five sites on the mitral annulus included peak early myocardial tissue velocity (E′), peak late (or atrial) myocardial tissue velocity (A′) and the ratio E′/A′. Standard pulsed-wave Doppler transmitral and pulmonary vein flow indices were also recorded along with measurements of body mass, heart rate, blood pressures and cardiac troponin T (cTnT), a biomarker of myocyte damage. Pre- to post-race changes in LV diastolic function were analysed by repeated measures ANOVA. Delta scores for LV diastolic function were correlated with each other and alterations in indices of LV loading. Diastolic longitudinal segmental and mean TDI data were altered post-race such that the mean E′/A′ ratio was significantly depressed (1.51 ± 0.34 to 1.16 ± 0.35, P < 0.05). Changes in segmental and global TDI data were not related to an elevated post-race HR, a decreased post-race pre-load or an elevated cTnT. The pulsed wave Doppler ratio of peak early transmitral flow velocity (E)/peak late (or atrial) flow velocity (A) was also significantly reduced post-race (1.75 ± 0.46 to 1.05 ± 0.30, P < 0.05); however, it was significantly correlated with post-race changes in heart rate. The lack of change in E/E′ from pre- to post-race (3.4 ± 0.8 and 3.3 ± 0.7, respectively) suggests that the depression in diastolic function is likely to be due to altered relaxation of the left ventricle; however, the exact aetiology of this change remains to be determined
