Mild Traumatic Brain Injury, Dementia, and Exercise: Increasing White Matter Integrity in the Brain
Get PDFNumerous studies have been carried out on mild traumatic brain injury (mTBI) and its treatment plans. This review covers the history of mTBI, differential diagnosis of the injury, and post-concussion syndrome (PCS). Furthermore, it explores the relationship between mTBI and aging, dementia, and Alzheimer’s disease and how exercise relates to changes in white matter in the human brain. From the reviewed literature, it is possible to see the relationship between mTBI injury and white matter: mTBI may lead to structural changes in white matter fibre tract integrity. Exercise can be used to respond to cases of mTBI as it encourages the formation of new connections between neurons along with an increase in the production of new neurons. Aerobic exercise can lead to the replacement of damaged white matter as well as increased cognitive performance. This review demonstrates the possibility of using exercise to treat cases of PCS through white matter repair
Rising from the Ashes of a Western Blaze
No full textA review of research confirms that the neoliberal model of globalization in agricultural trade undermines food sovereignty and food-sharing practices in indigenous Ecuadoran fishing societies. This project examines the interrelated factors involving the displacement and poverty forced upon Ecuadorians in response to the lack of acknowledgement of their presence in and dependence on the mangrove ecosystem in Manabi, Ecuador (Latorre, 2013). It explores how food regimes are forged from historical thinking and emerge through neoliberal language (Fairbairn, 2010). Further, this project associates the fear of hunger in the homes of Western people (Bello, Walden, & Baviera, 2010) with the ignorance and displacement of the Manabi people, who are driven into greater hunger, poverty and consumption of unwanted chemicals (Altieri, 2010). I suggest that indigenous peoples maintain their eco-philosophies in order to regain their identities, which are synonymous with the cultural lands the corporate world has privatized (Morrison, 2011)
Mirvish Towers in Land Use and Urban Development Context
Get PDFThe Mirvish and Gehry Trio Towers are a currently proposed development that threatens the cultural identity of the entertainment district in Downtown Toronto. The development highlights the role of condofication and new mega projects in reshaping the downtown core as well as in giving an international identity to the city. The research included field observation to the site and its activities. It also included intensive research for primary resources whether newspaper or city planning documents. It can be concluded that the development proposes loss over gain due to the unsolved conflicts. The pressure by the owner and the international architect leaves the city planners hesitant about their decision
Black Residents of Toronto and the Police
No full textMembers of the Toronto Police Services serve and protect Torontonians. They engage in “carding,” which is the act of randomly stopping people and getting their information to create a database that later helps in police investigations. The Toronto police contend that these random stops alleviate crime and keep residents of Toronto safe. However, the outcomes of carding are grossly disproportionate with the aims of the practice. Studies reveal that 44% of people of colour reported being stopped by the police at least once whereas only 12% of white people reported being stopped by the police. The overrepresentation of people of colour in these procedures shows that racial profiling occurs in the system. Black Torontonians are stopped and questioned by the police not necessarily in relation to a crime, but based on assumptions and stereotypes about people of colour. This research is founded in various scholarly secondary sources as well as news articles on the topic. The goal of this research was to explore the broader implications of racial profiling in the daily lives of people of colour and how this might contrast to the dominant group in society. This research examines gender, race, and social class in relation to police carding
Effects of an Intervention on Maximal Aerobic Power
No full textObjective: to examine the efficacy of a self-paced guided active play (GAP) program in eliciting changes in aerobic power for children and adolescents (8-12 yrs). Methods: girls and boys (n=33) registered in summer camp where recruited to participate in a guided active play program (8 weeks) focused on active playing of self-paced cooperative games (1h/d; 5d/wk). Physical activity participation was assessed daily by attendance and accelerometry (ActiGraph GT3X+; 10s epoch) by vector magnitude (vm counts/min) for children/adolescents. Anthropometric (stature, weight, leg length, and maximal aerobic power [20m MSSR]) were collected prior to and following the program. Maturity status (MS) was estimated from anthropometric variables and used with multiple linear regression equations to predict days from age at peak height velocity (APHV). ANOVA (main effects) and tukey post-hoc test (individual group differences) were performed (p=0.05). Results: prior to the program, children (age: 9.8±1.3yrs; BMI: 20.7±2,6kg/m2; maturity offset: -4.2±1.0yrs) had an estimated aerobic power of 44.1±0.9 mlO2/kg/min; with boys (45.4±1.0 mlO2/kg/min) higher than girls (42.5±0.7 mlO2/kg/min) (p<0.05). In response to the GAP program, aerobic power improved by 4.3±3.8% (p<0.05) for all children, with girls > boys (p>0.05). Maturity status (MS) ranged from -2.4 to -7.0yrs; with the girls averaging (-3.7±1.0yrs) and boys (-4.4±1.2yrs). In general, the relationship between MS and improvement in aerobic performance was moderate (r=0.46), except for the girls that showed a good-very good relationship (r=0.76) (p<0.05). Conclusion: active playing of children’s games is associated with improvements in aerobic power and increases in AP are related to maturity status
"Why Not Stay a Little Longer?": Mobilities, Public Space, and Commuter Culture at York University's Keele Campus
No full textGeographical imagination is fundamentally individualistic and context specific, confined to a given space. Though it has been asserted that the world is experienced by individuals as they move through it and walking has been acknowledged as a powerful method of understanding and valuing space, it is important to recognize how a place can be devalued through constant mobility and become “placeless” (Cresswell, 2006). This placelessness can be achieved through the act of commuting and culture surrounding it, which channels and schedules a specific pattern of mobility (Cresswell & Merriman, 2011). This paper argues that, through the use of an urban intervention, students were enabled and empowered to alter and engage with the York University Campus. The intervention challenged the intended use of Campus Walk, interjected into mundane rhythms of daily commuter life, drew individuals out of their personal technospace into the broader social landscape, and, ultimately, allowed the space to be more than that of “passive mobilities” on a commuter campus

#OccupyGezi: On Twitter and Affective News
Get PDFOn the dawn of May 31, 2013, Istanbul’s riot police raided Gezi, a park recently occupied by activists standing against the threat of its destruction. On social media, pictures of the bloody police intervention went viral, sparking outrage and a political momentum that materialized throughout the country in the form of protests against the national government. Taking as a point of departure my personal experience of the events, this essay examines the use and effects of Twitter in the context of particular forms of civilian protests. In particular, I suggest that such tweets may contribute to the development of an affective environment that can foster a collective sense of belonging, association, and shared experience. First, I discuss media censorship of the initial protest in Istanbul. I then proceed with a discussion of the affective connotations of the messages and photographs shared on Twitter. In this regard, I also bring forward the cultural concept of “martyrdom” as a helpful analytical tool to explore these issues.Oppression creates the need and demand for recognition.— Halverson, Ruston, & Trethewey (2013, p. 321)
