			<title>The battle of the brands</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_150.html</link>
			<description><![CDATA[In an era where product parity is common, image can make all the difference. It is very difficult to create a truly unique product – especially when points of difference are easily imitated. <br />
<br />
Strong brands have strong identities, according to Michael Mulvey, assistant professor of marketing in the Telfer School of Management. Trying to win over consumers has become an identity contest where people make choices based on identity concerns and the nature of the emotionally-charged consumption experience promised by the brand. <br />
<br />
In order to create an effective representation, an appropriate image must be identified for the brand, the consumer, and the consumer-brand relationship. Marketers need to become “symbol-minded” and draw upon archetypes to use as models of identity. Success requires an alignment between customer and brand archetypes to create a coherent whole. <br />
<br />
The meaningfulness of competing brand identities is sharpened when put into a system: compare Pepsi’s youthful exuberance with Coke’s stoic traditionalism.<br />

			<title>Snapshot of francophone minorities</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_149.html</link>
			<description><![CDATA[Today, we often hear of the issues faced by ethnic minorities trying to immigrate to Canada. But what about the vibrant communities that have been an integral part of Canada for hundreds of years? Anne Gilbert, professor in the Department of Geography, studies “national” minorities, such as the franco-ontarian community, who are set apart from others due to their historical presence and their desire to form small societies within the country.<br />
<br />
As Research Director at the Centre for Interdisciplinary Research on Citizenship and Minorities (CIRCEM), she is particularly interested by francophone minorities and the effect of the environment on social practices and political identity. <br />
<br />
Gilbert is essentially preoccupied with the impact of these minorities on social practices and cultural identity. From 2002 to 2006, she undertook extensive field work in order to better understand the processes leading to the vitality of francophone communities across the country. She is currently working on a book about the various dimensions of the communities’ dynamism.<br />
<br />
In the next few years, she will closely examine the representation of the francophone community in the Ottawa region.<br />

			<title>Giving people with dementia a pleasant place to live</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_148.html</link>
			<description><![CDATA[People suffering from advanced stages of dementia may have a tendency to wander, be agitated and resist care. Their behaviour can jeopardize their quality of life and can cause enormous stress for themselves and their loved ones. <br />
<br />
Some long-term homes have designed special units to help reduce these disruptive behaviors and increase residents’ quality of life. <br />
<br />
Designs often include barrier-free rooms and corridors, homey environments, common living rooms to encourage interaction, safe outdoor areas, and kitchens with open access to residents.  <br />
Linda Garcia, the Director of the Audiology and Speech-Language Pathology Program, is involved in a study aimed at demonstrating the extent to which architectural design features relate to the levels of disruptive behaviors in patients with dementia. The goal is to develop a theory about whether the social and personal environments found within these settings promote greater positive interactions among residents, staff, and visitors. The study is set in locations in Toronto, Calgary and Ottawa and was funded by the Alzheimer Society of Canada. <br />
<br />
Garcia and her research partners measured the behavior and severity of dementia, gathered information about architectural design features, looked at incidence reports and staffing levels, examined communication skills between staff and residents, gauged noise level, conducted focus groups and observed residents in these environments. The data is still being analyzed, but so far Garcia and her colleagues have found that one of the most important elements for improved quality of life relates to the approach and consistency demonstrated by the staff.]]></description>

			<title>Human Rights and Corporate Accountability</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_147.html</link>
			<description><![CDATA[International corporations reap the benefits of the world having shrunk into a global village. Yet the accountability they would have in their home state is not always present in host countries, in some cases causing human rights to fall victim.  <br />
<br />
Associate professor Penelope Simons’ work examines international corporate governance and, in particular, the regulation of the human rights impacts of transnational corporate activities and the intersection between human rights, international economic law and transnational corporate activity. <br />
<br />
Simons co-authored a paper examining the international legal responsibility of home states for violations of human rights by transnational corporate actors operating in other countries. Presently, Simons is working on a manuscript for a book with University of Toronto law professor Audrey Macklin and Georgette Gagnon, a Toronto human rights lawyer. The book is due to be published in 2008 and investigates the governance gap in relation to the accountability of transnational corporations operating in conflict zones or repressive regimes for violations of international human rights standards, and develops a case for home state regulation. <br />
<br />
The original research was funded by a grant from the Law Commission of Canada and the Social Sciences and Humanities Research Council.  <br />
<br />
In addition, Simons is currently writing a paper examining the relationship between right to adequate food, the World Trade Organization Agreement on Agriculture, and transnational corporate activity in agricultural markets. <br />

			<title>Finding justice in post-conflict Rwanda</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_146.html</link>
			<description><![CDATA[In the wake of a genocide that claimed the lives of up to one million Rwandans, the African country is now facing the challenge of bringing the many perpetrators to justice.<br />
<br />
The International Criminal Tribunal for Rwanda has completed only 33 cases since trials began in 1997 and has spent about $1 billion. National courts, though cheaper and faster to run, would still take over 100 years to try all those suspected of involvement in the 1994 mass killings.<br />
<br />
The government created popular courts based on a traditional mechanism known as gacaca, whereby the accused are judged and sentenced by non-jurists in their own communities — a controversial move. <br />
<br />
Stephen Brown, an associate professor in uOttawa’s School of Political Studies, is researching transitional and traditional justice in Rwanda as part of a larger project led by Professor Chandra Lekha Sriram, director of the University of East London's Centre on Human Rights in Conflict, and funded by the British Academy. The project investigates post-conflict peace building, focusing on the rule of law. It’s particularly interested in the international community’s contributions. <br />
<br />
Brown previously conducted research in Rwanda in 2004 on behalf of the International Development Research Centre.<br />

			<title>Reinventing the wheel</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_145.html</link>
			<description><![CDATA[Few technological innovations can match the dramatic impact of the automobile, with its global implications for culture, economic activity and the fate of our environment. While the latest generation of automotive technology is less polluting and more fuel efficient than ever before, its sheer dominance in our everyday lives continues to pose a major ecological challenge. Professor Matthew Paterson of the School of Political Studies argues that we cannot fully meet that challenge until we understand just how and why these vehicles have become so dominant. Only in this way can we see how to change the political and social institutions sustaining the role of automobiles in our world, and avoid the crises that will occur when that role collides with the physical ability of our society — and our planet — to support all that traffic.<br />

			<title>Writing the book on Leo Tolstoy</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_144.html</link>
			<description><![CDATA[Much of the world's great literature has come from Slavic-speaking countries, particularly Russia. Russian literature has dealt with burning issues of the day, universal in scope, and contemporary in relevance. One of the best known contributors is Leo Tolstoy, author of weighty tomes such as War and Peace. It’s through his writings, which are rich with his concern for the unity of people and his respect for ethnic diversity, that Western readers can gain a rare insight into Russian culture. Andrew Donskov, the founder and director of the Slavic Research Group at uOttawa, says Sofia Tolstaya’s autobiography contains nuggets of valuable information about her husband’s daily existence. It’s considered the most important document for Tolstoy studies that still remains unpublished, inasmuch as it sets forth many facts and commentaries concerning Tolstoy’s life and work to which his wife alone was privy. The exclusive publication rights to Tolstaya’s “My Life” in English are held by the Slavic Research Group at the University of Ottawa.<br />

			<title>Shedding light on modern slavery</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_143.html</link>
			<description><![CDATA[Europeans imposed colonial rule violently upon Africa, paving the way for oppression and exploitation. They forced hundreds of thousands of Africans to work for insignificant pay or nothing at all, justifying such actions with the claim that Africans had to be "civilized" through labour. Eric Allina-Pisano, at the new Master’s Program in International Development and Globalization and the Department of History is examining how colonial rule in Mozambique marked the emergence of modern slavery, which differed from previous forms. Earlier slaveholders never denied their workers were held captive under the lash, but colonizers camouflaged coercion behind claims that Africans were employed under imaginary contracts. Abolition-era slavery proponents alleged that Blacks’ supposed inherent inferiority justified their subjugation, while modern slavery claimed that forcing “uncivilized Africans” to work would improve their “moral and material well-being.” Though earlier slave-owners treated bondservants with great brutality, they paid large sums of money for them and regarded them as valuable investments. In contrast, the exploiters of Africa’s modern slaves paid virtually nothing for their labour, treating them as expendable “men-machines.” Allina-Pisano also addresses how the colonial era established some of the political and economic conditions that still sustain slavery today, pointing to how the colonial period was the "midwife" of contemporary forms of servitude in Africa.<br />

			<title>Keeping swimmers safe in Canada’s North</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_142.html</link>
			<description><![CDATA[The prevention of water-related fatalities in the Northwest Territories and Nunavut will require the involvement of community members at the grassroots level. Audrey Giles, an assistant professor in the School of Human Kinetics, is working to save lives by examining northern indigenous cultural practices and the role they play in Aboriginal northerners’ involvement in aquatic-based activities, leadership programs and conceptions of water safety and risk. With the help of a grant from the Social Sciences and Humanities Research Council, Giles is studying the Northwest Territories Aquatics Program, which has been operating since 1967. She argues that up until now the program was largely based upon Euro-Canadian standards and values concerning water safety, leadership and risk perception. Giles will learn from the pitfalls experienced by the program to determine an improved method of disseminating drowning prevention and health-oriented information that is tailored to meet the needs and interests of the northern people it is trying to help. <br />

			<title>Managing the melting pot</title>

			<description><![CDATA[Modern cities are more culturally diverse than at any time in human history, as urban landscapes teem with individuals representing a wide range of living standards, social attitudes, and lifestyle choices. University of Ottawa social geographer Brian Ray explores the way people organize their everyday lives in busy Canadian cities, looking specifically at groups such as immigrants or refugees living in ethnically distinct neighbourhoods, where they could be at risk of becoming isolated from mainstream society and denied many of the advantages of living in this country. By looking at how some parts of the population become physically and economically marginalized, his work can help municipal authorities understand the underlying causes of these conditions, as well as actions that might prevent the emergence of major social problems.<br />

			<title>The virtual engine that could</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_140.html</link>
			<description><![CDATA[Making the next generation of gas turbine jet engines more energy efficient and environmentally friendly is an expensive proposition, calling for the limited production of components to build prototypes that simply might not work. For just that reason, mechanical engineering Professor Stavros Tavoularis has been refining a virtual engine that could yield similar test results at far less cost. He is conducting extensive three-dimensional computer simulations, based on a complex mathematical description of the air flow and gas combustion that takes place within this kind of engine. The resulting model can be fine-tuned simply by altering some of the many parameters in different software programs, rather than having to construct physical parts from scratch. Supported by the giant aerospace manufacturer Pratt &amp; Whitney, this work promises to make the evolution of aircraft engine design much more efficient.<br />

			<title>The changing face of the family</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_139.html</link>
			<description><![CDATA[From culture to culture, families remain the enduring heart of human society, but modern laws and technology are causing this traditional institution to evolve more rapidly than ever before. Political efforts to establish equality between the sexes, combined with laws that are starting to look beyond definitions based on two-parent, heterosexual households, have led many observers to conclude that we are approaching an historic juncture in the very meaning and importance of the family. Marie-Blanche Tahon, a professor in the Department of Sociology and Anthropology, criticizes the tendency to reduce the relationships within the family to little more than contractual obligations. She suggests that laws governing families in Canada should be seen in a new light, taking into account some overlooked distinctions between perceptions of individual rights and the need to foster commitments toward domestic activities such as parenting.<br />

			<title>Considering an island set in challenging waters</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_138.html</link>
			<description><![CDATA[Few places on earth represent a geographic and historical crossroads as dynamic as Taiwan. With its political status threatened by China, this relatively small island has nevertheless emerged as a major economic power, nurturing a diverse culture characterized by various waves of invasion and migration. In fact, Taiwan's identity has been shaped by influences from Austronesian indigenous peoples, Dutch colonization, Chinese migration, Japanese rule, and contested ethnic relations since the Republic of China came to the island in 1945. Scott Simon, an associate professor in the Department of Sociology, has been exploring different aspects of this complex identity for more than 10 years, including five years in Taiwan with the country’s leading research institute, Academia Sinica. He recently published a book that examines a number of key issues that emerged during the second half of the 20th century, as seen from the perspective of members of the traditional leather-tanning industry in Southern Taiwan. Through this social lens, he offers a view of the conflicts and campaigns that emerged during an extended period of martial law, followed by the emergence of democratic institutions that govern the nation today. Funded by SSHRC, he is currently doing in-depth field research on the island's Austronesian peoples, their historical experiences with colonialism and development, and their efforts to negotiate a more equal relationship with the state. <br />

			<title>The dangers of endangered species legislation</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_137.html</link>
			<description><![CDATA[Legislative efforts to save endangered species may be drafted with the best of intentions, and yield the worst of results. Any protection may focus exclusively on specific plants or animals, for example, while ignoring obvious threats to their physical habitat, which might be the reason the species is threatened in the first place. Prompted by fears that the Government of Ontario was saddled with just this kind of legislation, Department of Biology Professor Jeremy Kerr collaborated with colleagues across the province to draft a letter outlining how to correct the shortcomings of this approach. Endorsed by some 150 of his counterparts from across Ontario, the letter captured the attention of the government, which has revised its legislation accordingly. The new version does stipulate habitat protection, as well as some flexibility to allow for socio-economic development rather than strictly declaring some places off limits for the sake of an endangered species. Above all, Kerr explains, the new law is intended to transfer responsibility to the general administration of government, so that actions to save an endangered species will emphasize non-partisan scientific input, transcending the preferences of any particular minister or government. Before that happens, however, the proposed legislation must make its way through the government bureaucracy before the next provincial election this fall. In the meantime, Kerr is watching patiently and closely.<br />

			<title>The Love Nurse reminds parents about their feelings for one another</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_136.html</link>
			<description><![CDATA[Passionate love paves the way for pregnancy and childbirth, but this rich emotion can fade with the daily demands of raising an infant. According to Viola Polomeno, an assistant professor in the School of Nursing, this loss of passion is not inevitable and there are important reasons to prevent it. Intimacy and sexuality enable parents to maintain a central part of their relationship as well as reinforcing a bond that lies at the heart of any family. Professor Polomeno offers workshops showing parents how to remain friends and lovers. She is also examining perinatal sexuality, this relationship between love and health, by assessing the knowledge and attitude of nurses in this area. Other projects are comparing the perception of nurses and couples with regard to intimacy during pregnancy, and the development of guidelines for the safe use of sex toys while pregnant. Eventually she hopes to develop a training program for health care professionals in perinatal health. Such goals are why Dr. Polomeno is known as the "Love Nurse", addressing academic audiences as well as French and English mass media about the need for couples to remember that they are always a couple, regardless of their new role as parents.

			<title>Calling all glutamate receptors!</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_135.html</link>
			<description><![CDATA[The intricate network of cells in our brains can be severely compromised by a specific class of organic compounds called excitotoxins, some of which occur naturally in the brain. The best known of these compounds is glutamate, which acts as a major neurotransmitter by stimulating and exciting brain cells through specific glutamate receptors. During major events such as stroke, overstimulation of these receptors induces cells to kill themselves. This process often impairs much of the central nervous system’s function, resulting in conditions such as paralysis or loss of language skills. These effects can also be caused by compounds from outside the brain, such as aspartame and monosodium glutamate (MSG) found in manufactured food products. While the role of glutamates and glutamate receptors in the brain and central nervous system has been well established, their presence in other parts of the body was largely unknown until recently. Olga Pulido, a professor in the Department of Pathology and Laboratory Medicine and a Medical Specialist with Health Canada, has been among the first to examine the distribution and activity of these receptors in the body’s tissues. She and her colleagues are comparing and contrasting the role of these receptors with those found in the brain, attempting to understand how they work and what part they play in maintaining our health. Their most recent work, which is soon to appear in the journal Toxicologic Pathology, demonstrates for the first time the presence of glutamate receptors in human heart.<br />

			<title>A refined and re-defining fuel</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_134.html</link>
			<description><![CDATA[It can be easy to think of diesel fuel as being just another non-renewable source of energy, extracted from crude oil and generating emissions that contribute to pollution and climate change. However, diesel can also be derived from organic sources such as vegetable oils and animal fats, containing none of the sulphur or petrochemical compounds found in conventional fossil fuels. Known as biodiesel, it is renewable, biodegradable, and best of all, will run in any diesel engine on the road today. Dr. Marc Dubé, who chairs the Department of Chemical Engineering, and his colleague Professor André Tremblay, are seeking to make this alternative even more attractive by improving the methods for producing it. As part of the Ottawa Biodiesel Research Group, they have developed a new reactor to produce higher purity biodiesel from waste oils, such as those used by restaurants to fry foods. By employing a semi-permeable membrane, they have introduced a physical barrier that prevents most process impurities from finding their way into the final product. The result is a biodiesel fuel of exceptional quality which meets all international fuel standards, giving it a competitive advantage in the crowded market for automotive fuels.<br />

			<title>Getting to the bottom of lake deposits</title>
			<link>http://www.research.uOttawa.ca/excellence-discoveries-details_133.html</link>
			<description><![CDATA[However calm and smooth the surface of a lake might appear to be, what is happening below is complex and dynamic. Sedimentary particles are being transported and transformed through a combination of various physical, chemical and biological processes. Sorting out these activities is essential to understanding not just the way lake sediments form naturally, but how human interference can affect those sediments, along with the quality of the water and the well being of anything living in it. Ivan L’Heureux, a professor in the Department of Physics, belongs to an ambitious interdisciplinary group dedicated to making an unprecedented analysis of the structure and evolution of lake sediments. As a specialist in non-linear systems, he is using powerful computational techniques in order to understand the basic processes occurring in lake sediments, thus shedding new light on hazards that could be facing us in one of the most fundamental features of our environment.<br />

			<description><![CDATA[If hydrogen is ever to replace conventional energy sources such as coal, oil, or natural gas, we will have to find efficient ways of using this abundant element to produce power. Javier Giorgi, an assistant professor in the Department of Chemistry, is looking for just that. Using ultra-high-vacuum chambers and sophisticated spectrographic analysis, he is studying the chemical processes taking place on the surface of the electrodes within fuel cells, where hydrogen molecules react with catalysts in order to generate electricity. Through the use of model systems that employ different types of reactive material, this work is aimed at refining fuel cell design to make this promising technology more cost effective. Such improved efficiency will also be crucial to the development of economically viable hydrogen reformers, which would make it possible to use these fuel cells to produce hydrogen in a building or a vehicle as it is needed, rather than having to store this volatile gas in large quantities. Giorgi and his colleagues are therefore evaluating the performance of such equipment using pilot versions of fuel cell reactors and refuelling stations that they have built for themselves.<br />

			<title>Toward a better understanding of work-life balance</title>

			<description><![CDATA[There is a great deal of commentary about the stresses of the modern, high-tech workplace, much of it focusing on the challenges many individuals confront in balancing their personal lives and their careers. As familiar and widely recognized as this issue may be, most of this discussion remains limited to anecdotal observation, with little in the way of objective, scientific analysis. Laurent Lapierre, an assistant professor in the School of Management, has been introducing a more rigorous approach to this issue. Working with carefully identified groups of people, he has taken specific measures of how frequently work activities interfere with family life and vice versa, linking these conflicts to particular forms of behaviour by employees and their families, to specific "family-friendly" organizational and managerial practices, and to symptoms of stress. Past and future results of his research will help to define with more accuracy the factors that can enrich the quality of employees’ lives, both at work and away from the office. In this way, he is developing strategies that should enable organizations to get the most out of the people who work for them, while enabling those same people to enjoy all aspects of their lives.<br />
