Heart rate changes during the Valsalva maneuver in patients with isolated aortic insufficiency

To determine the possible relationship between left ventricular dilatation and heart rate changes provoked by the Valsalva maneuver (Valsalva ratio), we studied 9 patients with isolated chronic aortic insufficiency. Left ventricular systolic function was assessed by two-dimensional echocardiography and cardiac catheterization. All patients were asymptomatic (functional class I of the New York Heart Association). The left ventricular internal diameters and volumes were significantly increased in all patients. The asymptomatic patients had either normal or slightly depressed ejection fraction (EF>0.40). The Valsalva ratio of these asymptomatic patients showed no significant correlation with the left ventricular volumes or with the left ventricular ejection fraction. In other words, parasympathetic heart rate control, as expressed by the Valsalva ratio, was normal in the asymptomatic patients with left ventricular dilatation and preserved left ventricular ejection fraction. Therefore, left ventricular dilatation may not be the major mechanism responsible for the abnormal parasympathetic heart rate control of patients with acquired heart disease

Effects of female postmating odour on male sexual behaviour, in Heliconius butterflies /

The effects of the female postmating odour on male sexual behaviour were examined in Heliconius erato and H. charithonia (Lepidoptera: Nymphalidae). Predictions from the antiaphrodisiac hypothesis were tested using the two reproductive strategies of these species. Within the pupal mating strategy, results from behavioural experiments quantified and statistically tested dispersal rates of pupal-perched males to the presence of stimuli with and without the postmating odour. Results do not support an antiaphrodisiac function to the postmating odour. Similarly, within the adult courtship strategy, behavioural test results indicate that males do not alter their expenditure of energy in terms of either the duration or frequency of courtship behaviours elicited by females with and without the postmating odour. The data from both experiments did not support the antiaphrodisiac hypothesis for the function of the female postmating odour. A novel hypothesis predicting that the postmating female odour acts as an oviposition-deterring pheromone is presented.

Bonds away : baseball mythology and the 2007 home run chase

In 2007, Barry Bonds hit his 75 6th home run, breaking Hank Aaron's all-time record for most home runs in a Major League career. While it would be expected that such an accomplishment would induce unending praise and adulationfor the new record-holder, Bonds did not receive the treatment typically reserved for a beloved baseball hero. The purpose of this thesis is to assess media representations of the 2007 home run chase in order to shed light upon the factors which led to the mixed representations which accompanied BOlTds ' assault on Aaron's record. Drawingfrom Roland Barthes ' concept of myth, this thesis proposes that Bonds was portrayed in predominantly negative ways because he was seen as failing to embody the values of baseball's mythology. Using a qualitative content analysis of three major American newspapers, this thesis examines portrayals of Bonds and how he was shown both to represent and oppose elements from baseball's mythology, such as youth, and a distant, agrarian past. Recognizing the ways in which baseball is associated with American life, the media representations of Bonds are also evaluated to discern whether he was portrayed as personifYing a distinctly American set of values. The results indicate that, in media coverage of the 2007 home run chase, Bonds was depicted as a player of many contradictions. Most commonly, Bonds' athletic ability and career achievements were contrasted with unflattering descriptions of his character, including discussions of his alleged use of performance-enhancing substances. However, some coverage portrayed Bonds as embodying baseball myth. The findings contribute to an appreciation of the importance of historical context in examining media representations. This understanding is enhanced by an analysis of a selection of articles on Mark McGwire 's record-breaking season in 1998, and careful consideration of, and comparison to, the context under which Bonds performed in 2007. Findings are also shown to support the contemporary existence of a strong American baseball mythology. That Bonds is both condemned for failing to uphold the mythology and praised for personifYing it suggests that the values seen as inherent to baseball continue to act as an American cultural benchmark.

The carbon disclosure project, an evolution in international environmental corporate governance : motivations and determinants of market response to voluntary disclosures

This paper examines the factors associated with Canadian firms voluntarily disclosing climate change information through the Carbon Disclosure Project. Five hypotheses are presented to explain the factors influencing management's decision to disclose this information. These hypotheses include a response to shareholder activism, domestic institutional investor shareholder activism, signalling, litigation risk, and low cost publicity. Both binary logistic regressions as well as a cross-sectional analysis of the equity market's response to the environmental disclosures being made were used to test these hypotheses. Support was found for shareholder activism, low cost publicity, and litigation risk. However, the equity market's response was not found to be statistically significant.

Uncomfortable Comparisons : The Canadian Truth And Reconciliation Commission In International Context

The Canadian Truth and Reconciliation Commission on Indian Residential Schools is a novel foray into a genre previously associated with so-called “transitional” democracies from the post-Communist world and the global South. This basic fact notwithstanding, a systematic comparison with the broader universe of truth commission-hosting countries reveals that the circumstances surrounding the Canadian TRC are not entirely novel. This article develops this argument by distilling from the transitional justice literature several bases of comparison designed to explain how a truth commission’s capacity to promote new cultures of justice and accountability in the wake of massive violations of human rights is affected by the socio-political context in which the commission occurs; the injustices it is asked to investigate; and the nature of its mandate. It concludes that these factors, compounded by considerations unique to the Canadian context, all militate against success. If Canadian citizens and policymakers fail to meet this profound ethIcal challenge, they will find themselves occupying the transition-wrecking role played more familiarly by the recalcitrant and unreformed military and security forces in the world’s more evidently authoritarian states.

Periódico escolar.

Este proyecto surgió con la idea de realizar una serie de actividades por parte de un grupo de profesores y profesoras preocupados por llevar a cabo actividades que resultasen motivadoras para el alumnado, a la vez que de forma globalizadora trabajaran los contenidos básicos del currículum. A esto se le a��adió la necesidad de conocer el entorno en el que viven los alumnos y alumnas desde una perspectiva diferente a lo cotidiano, resaltando hechos importantes, destacando personalidades, analizando situaciones, etc. De esta situación ha surgido la idea de realizar el periódico que ha actuado como elemento eje en la práctica educativa, en la que además de los aspectos anteriormente mencionados se han trabajado aspectos tan importantes como la interculturalidad, la coeducación, la educación para la paz o la solidaridad.
