Response To Exercise

Cardiac remodelling occurs in response to exercise and is generally beneficial for athletic performance due to the increase in cardiac output. However, this remodelling also may lead to an increased prevalence of cardiac murmurs and arrhythmias. In most cases, these are not considered to be significant. However, in some cases, there may be potentially deleterious consequences. Whilst sudden cardiac death (SCD) is a rare occurrence, the consequences are catastrophic for both the horse and potentially the rider or driver. Furthermore, the sudden death of a horse in the public arena has negative connotations in regards to public perception of welfare during equestrian sports. Prediction of which individuals might be susceptible to potential deleterious effects of exercise is a focus of interest in both human and equine athletes but remains a challenge because many athletes experience cardiac murmurs and exercise-induced arrhythmias that are clinically irrelevant. This review summarises the effects of exercise on cardiac remodelling in the horse and the potential effects on athletic performance and SCD. The use of biomarkers and their future potential in the management of athletic horses is also reviewed.

The Way

Several researchers operating in the sociological field have recently theorised that genetics and biotechnologies are at the core of the public perception of science. The present study aims at verifying empirically whether or not this is mirrored in Italian mass media, as well as at analysing the topics most frequently present in Italian newspapers and the economic and editorial reasons behind the results of editorial choices. Besides, it provides statistics about the major Italian newspapers published in the last third of 2002. This period has been chosen because some important news was published in December: it consequently offered the chance to carry out a long-term analysis as well as a study of the most important differences - in content and editorial lay-out - between scientific articles which are published in the appropriate sections inside the newspaper and those which make the front page. Ours are going to be purely quantitative considerations; but, from the point of view of the content, the data are sufficient to identify various narrative currents. These currents could be the object of further research on the frames used to contextualize the news and the reasons (anthropological, socio-cultural and editorial) for the way they are used by editorial staffs.

It seems that educational system in Nigeria has undergone only quantitative improvement in terms of number of schools and students’ enrolment. However, there has been little effort in respect to the capacity to manage them through provisions of adequate financial, human, material and physical resources. Physical and material resources in secondary schools were discovered to be inadequate and poorly equipped. Some of the secondary school buildings were dilapidated, also the allocated financial resource, teaching and non-teaching staff are grossly inadequate compared with the students’ enrolment. The public, the Ministry of Education and other stakeholders in education are expressing serious concern about the consistency of the poor performance of secondary school students especially in mathematics. Increase in population and the government’s free education programs make people want to take advantage of the education provided. Provision of both professionally qualified and non-qualified teachers by government and non-state providers of education also appear not to ameliorate the problem of declining performances in mathematics. The effect of all these on the public secondary school student academic performance in mathematics concern the researchers of this study. It is against this background that the study sought to empirically investigates effect of resource factors and quality of instruction on performance in mathematics of Nigeria secondary school students.

This paper briefly summarizes evidence for the influence of popular films on public perception of government and on public policy.  Two films examined through the lens of public administration, and the lessons they teach about public administration, are exposed.  One film, Ghostbusters conveys a strongly negative image, and the other, A Thousand Heroes a strongly positive message.  Only Ghostbusters was and remains popular and profitable.  Public information efforts by government and the public administration community have been limited or reactive.  The authors argue for the increased support for public information initiatives such as those of the Public Employees Roundtable (PER) and  the American Society of Public Administration (ASPA).

False Accusations

When the hashtag #metoo began to circulate in digital and social media, it challenged a familiar interpretation of those who are raped or sexually harassed as victims, positioning women as embodied agents. Yet, almost exactly a year after the #metoo movement shot to visible prominence, a different, though eerily similar, story began to circulate on the same multi-media platforms as #metoo: a story about white male victimhood. Powerful men in positions of privilege (almost always white) began to take up the mantle of victimhood as their own, often claiming to be victims of false accusations of sexual harassment and assault by women. Through the analysis of five public statements by highly visible, powerful men who have been accused of sexual violence, I argue that the discourse of victimhood is appropriated not by those who have historically suffered but by those in positions of patriarchal power. Almost all of the statements contain some sentiment about how the accusation (occasionally acknowledging the actual violence) ‘ruined their life’, and all of the statements analyzed here center the author, the accused white man, as the key subject in peril and the authors position themselves as truth-tellers about the incidents. These statements underscore certain shifts in the public perception of sexual violence; the very success of the #metoo movement in shifting the narrative has meant that men have had to defend themselves more explicitly in public. In order to wrestle back a hegemonic gender stability, these men take on the mantle of victimhood themselves.

The Human Condition

This article examines Canadian author Shaughnessy Bishop-Stall’s 2004 memoir Down to This: Squalor and Splendour in a Big-City Shantytown through the notions of marginalia and the ordinary in order to question dichotomic representations of homelessness. It explores how the author moves beyond binaries, interrogating the dichotomy ordinary/out of the ordinary lives by narrating his ethical encounter with the other (Butler, 2004). The text is written as a journal where Bishop-Stall describes his personal journey through homelessness; and more importantly, it gives a voice to the other down-and-out people in notorious Toronto’s Tent City. The characters’ unreliable and fragmented storytelling uncovers the lives of the faceless others. I contend that in Down to This individuals’ life stories are connected to realities which question binaries through the re/mapping of ordinary experiences and affects; they disintegrate the opposition materiality vs abstraction, or as I argue, exclusion vs inclusion (out of the ordinary/ordinary). Down to These bridges the private details of the residents’ life stories, and the public perception of the problem of homelessness, illustrating how everyday moments of precarity intersect with wider political issues. In the process, the narrative also questions the binary attitudes of exclusion (disfranchisement) and inclusion (privilege). This literary strategy gives the constellation of stories a profound illuminating vision of the human condition. I show my point by drawing on the of marginalia (Kistner 2014), and by analysing the characters’ narratives of precariousness through the notions of editing and affective assemblage (Gerlach, 2015; Hamilakis, 2017).

The Core

In this article, we explore how the discourses around gender are evolving at the core of Brazilian politics. Our focus lies on the discourses at the public hearing on the bill 3.492/19, which aimed at including “gender ideology” on the list of heinous crimes. We aim to identify the deputies’ linguistic representation of social actors as pertaining to in- and outgroups. In addition, the article analyzes through Critical Discourse Analysis how the terminology gender is represented in this particular hearing. The analysis shows how some of the conservative parliamentarians give a clearly negative meaning to the term gender, by labeling it “gender ideology” and additionally connecting it with heinous crimes. We propose that the re-signification of “gender ideology,” from rhetorical invention to heinous crime, is not only an attempt to undermine scientific gender studies but also a way for conservative deputies to gain more political power.

Response To Exercise

Exercise frequently alters the metabolic processes of oxidative metabolism in athletes, including exposure to extreme reactive oxygen species impairing exercise performance. Therefore, both researchers and athletes have been consistently investigating the possible strategies to improve metabolic adaptations to exercise-induced oxidative stress. N-acetylcysteine (NAC) has been applied as a therapeutic agent in treating many diseases in humans due to its precursory role in the production of hepatic glutathione, a natural antioxidant. Several studies have investigated NAC’s possible therapeutic role in oxidative metabolism and adaptive response to exercise in the athletic population. However, still conflicting questions regarding NAC supplementation need to be clarified. This narrative review aims to re-evaluate the metabolic effects of NAC on exercise-induced oxidative stress and adaptive response developed by athletes against the exercise, especially mitohormetic and sarcohormetic response.

Despite the steady increase in female participation in sport over the last two decades, comprehensive research on interventions attenuating the influence of female menstrual physiology on performance remains scarce. Studies involving eumenorrheic women often only test in one menstrual phase to limit sex hormone variance, which may restrict the application of these findings to the rest of the menstrual cycle. The impacts of nutrition-based interventions on athletic performance throughout the menstrual cycle have not been fully elucidated. We addressed this gap by conducting a focused critical review of clinical studies that reported athletic outcomes as well as menstrual status for healthy eumenorrheic female participants. In total, 1443 articles were identified, and 23 articles were included. These articles were published between 2011 and 2021, and were retrieved from Google Scholar, Medline, and PubMed. Our literature search revealed that hydration-, micronutrient-, and phytochemical-based interventions can improve athletic performance (measured by aerobic capacity, anaerobic power, and strength performance) or attenuate exercise-induced damage (measured by dehydration biomarkers, muscle soreness, and bone resorption biomarkers). Most performance trials, however, only assessed these interventions in one menstrual phase, limiting the application throughout the entire menstrual cycle. Improvements in athletic performance through nutrition-based interventions may be contingent upon female sex hormone variation in eumenorrheic women.
