The Acidic Domains Of The Toc159 Chloroplast Preprotein Receptor Family Are Instrinsically Disordered Protein Domains, Lynn G.L. Richardson, Masoud Jelokhani-Niaraki, Matthew D. Smith

Biology Faculty Publications

Background: The Toc159 family of proteins serve as receptors for chloroplast-destined preproteins. They directly bind to transit peptides, and exhibit preprotein substrate selectivity conferred by an unknown mechanism. The Toc159 receptors each include three domains: C-terminal membrane, central GTPase, and N-terminal acidic (A-) domains. Although the function(s) of the A-domain remains largely unknown, the amino acid sequences are most variable within these domains, suggesting they may contribute to the functional specificity of the receptors.

Results: The physicochemical properties of the A-domains are characteristic of intrinsically disordered proteins (IDPs). Using CD spectroscopy we show that the A-domains of two Arabidopsis Toc159 …

Life Domain Research Report Series: Family (2010 Update), Gary Cameron, Lirondel Hazineh, Karen Frensch, Michele Preyde

Partnerships for Children and Families Project

A key consideration in understanding the long term community adaptation of children and youth involved with residential treatment or intensive family services is the role that family plays in sustaining or eroding gains made by children and youth in treatment (Frensch & Cameron, 2002). This report includes a summary of family descriptive information, the nature of family relationships, and indicators of family functioning for children and youth who have participated in children’s mental health services.

Data were collected about youth who had been involved with children’s mental health residential treatment (RT) or intensive family service programs (IFS), designed as an …

Life Domain Research Report Series: Youth And Parent Health And Well Being (2010 Update), Michele Preyde, Karen Frensch, Gary Cameron, Lirondel Hazineh

Partnerships for Children and Families Project

Children and youth who have participated in children’s mental health services often continue to live with a variety of emotional and behavioural challenges after service involvement has ended (Cameron, de Boer, Frensch, & Adams, 2003). A key consideration in understanding the long term community adaptation of these children and youth is the ongoing management of emotional and behavioural challenges and the impact these challenges have in the daily lives of youth and their families. Several standardized measures of mental health, physical health, stress, and quality of life were used to assess parental and youth functioning in the life domain of …

Working Report #3: Use Of Legal Measures And Formal Authority (Service Provider Perspectives), Lirondel Hazineh, Gary Cameron

Partnerships for Children and Families Project

The focus of this report is, across service delivery models, how front-line protection workers viewed their formal authority role and the extent to which they relied on legal measures in order to achieve protection goals. The analysis is guided by several overarching questions including (1) how does each model view the use of legal measures and formal authority? (2) How does each model impact service providers’ actual use of legal measures? (3) What value do workers place on the authority figure role? And (4) how effective is the use of formal authority in reaching child protection goals?

Type of program …

Working Report #1: Service Model Accessibility (Service Provider Perspectives), Lirondel Hazineh, Gary Cameron

Partnerships for Children and Families Project

This report examines the differences in service accessibility across central, integrated, and school/community based child welfare service delivery models including geographic proximity to families, acceptability of the setting to families, and accessibility expectations of service providers. Results suggest that accessibility characteristics of the model can make a significant difference to front-line service delivery from the perspective of front-line protection workers.

A defining feature of the community and school based child welfare models was increased accessibility for families and workers. Through making themselves more accessible, the community and school based settings had some significant service delivery advantages including more regular, varied, …

Working Report #2: Client And Community Relations (Service Provider Perspectives), Lirondel Hazineh, Gary Cameron

Partnerships for Children and Families Project

This report addresses two important questions: how much emphasis is placed on building positive relationships with families and communities across agency based, integrated service, and community and school based models of service delivery? And, how successful is each model at building relationships, minimizing stigma for families, and improving the image of child welfare in the community?

Educating clients and the community about child welfare services was identified as an important role for workers in some sites and not in others. While families’ fears of child protection services were a concern, some workers also expressed a fear of their clients and …

Working Report #4: Range Of Services (Service Provider Perspectives), Lirondel Hazineh, Gary Cameron

Partnerships for Children and Families Project

This working report examines the differences in range of services across central, integrated, and school/community based sites including referrals to other services, direct support, advocacy, and collaborative efforts to provide services to families. Which models provide the most service options for families? How do service providers view the service options available to them in their work with families? How helpful are services to families?

The range of services available within agency based settings seemed the narrowest in comparison to other types of service delivery settings. Integrated service models appeared to increase the range and access to many formal services. Community …

Working Report #7: Helping Relationships In Child Welfare (Parent Perspectives), Lirondel Hazineh, Gary Cameron, Karen Frensch

Partnerships for Children and Families Project

This report examines the nature of first contacts in child welfare, the level of contact between families and service providers, and the quality of relationships over time across central, integrated, and accessible service delivery models.

I. First Contacts Clarity, consultation, use of power, and positive shifts in perception were central issues identified by parents when discussing their experiences of first contacts with child welfare. More parents in accessible sites had experiences with workers who were clear and provided a sense that they would be supported. Within the accessible sites a strong philosophy of collaboration emerged between worker and participant. Participants …

Miniature High-Sensitivity High-Temperature Fiber Sensor With A Dispersion Compensation Fiber-Based Interferometer, Bo Dong, Li Wei, Da-Peng Zhou

Physics and Computer Science Faculty Publications

A miniature high-sensitivity, high-temperature fiber sensor with an interferometer based on a bare small-core-diameter dispersion compensation fiber (DCF) is reported. The sensing head is a single-mode-fiber (SMF) DCF configuration formed by a 4 mm long bare DCF with one end connected to the SMF by a fusion splicing technique and the other end cleaved. Due to the large mode index difference and high thermo-optic coefficient induced by two dominative interference modes, a miniature high-temperature fiber sensor with a high sensitivity of 68.6 pm/°C is obtained by monitoring the wavelength shift of the interference spectrum. This type of sensor has the …

Life Domain Research Report Series: Social Connections And Community Conduct (2010 Update), Lirondel Hazineh, Karen Frensch, Michele Preyde, Gary Cameron

Partnerships for Children and Families Project

Understanding how youth participate in social networks with peers and friends, engage in social or leisure activities, and more generally forge healthy relationships with others are key considerations in assessing overall well being of youth. Among a variety of emotional and behavioural challenges faced by children and youth involved with residential treatment or intensive family services may be their ability to negotiate relationships within social contexts (Cameron, de Boer, Frensch, & Adams, 2003).

Data were collected about youth who had been involved with children’s mental health residential treatment (RT) or intensive family service programs (IFS), designed as an alternative to …

Examining The Effect Of Pore Size Distribution And Shape On Flow Through Unsaturated Peat Using Computer Tomography, Fereidoun Rezanezhad, William L. Quinton, Jonathan S. Price, David Elrick, T.R. Elliot, Richard J. Heck

Geography and Environmental Studies Faculty Publications

The hydraulic conductivity of unsaturated peat soil is controlled by the air-filled porosity, pore size and geometric distribution as well as other physical properties of peat materials. This study investigates how the size and shape of pores affects the flow of water through peat soils. In this study we used X-ray Computed Tomography (CT), at 45μm resolution under 5 specific soil-water pressure head levels to provide 3-D, high-resolution images that were used to detect the inner pore structure of peat samples under a changing water regime. Pore structure and configuration were found to be irregular, which affected the rate of …

The Maritorious Melodrama: Film Noir With A Female Detective, Philippa Gates

English and Film Studies Faculty Publications

Feminist critics tend to disagree whether the parachuting of women into traditionally male roles—for example, that of detective—results in a feminist representation. The female detective of the 1930s, however, can be seen to offer a decidedly positive feminist hero in that she defies the stereotype of the “masculine” (i.e. unnatural) woman—especially when one considers the time in which she appeared and representations of female detectives in contemporary film. Despite popular conceptions of classical film, Hollywood did offer progressive representations of working women, ironically in the decade characterized by economic and social upheaval during the Depression. The prolific female detective of …

Rethinking Leninism, Alex Levant

Communication Studies Faculty Publications

This special section on ‘Rethinking Leninism’ emerges from sessions organized at the Society for Socialist Studies’ Annual Meetings, held at the Congress of the Humanities and Social Sciences in May 2009 at Carleton University in Ottawa, Ontario, Canada. The articles re-consider Lenin’s legacy, suggesting new ways of understanding his political thought and the implications for political strategies on the left today.

Life Domain Research Report Series: School And Employment (2010 Update), Karen Frensch, Lirondel Hazineh, Gary Cameron, Michele Preyde

Partnerships for Children and Families Project

Earlier research by the Partnerships for Children and Families Project on the daily living realities of youth and children involved with mental health services, particularly residential treatment, revealed the ongoing and pervasive nature of difficulties youth and children experienced in their academic functioning (Cameron, de Boer, Frensch, & Adams, 2003). As the education experience is such a large part of youth and children’s lives, we sought to better document how children and youth were performing in school in the current study.

Data were collected about youth who had been involved with children’s mental health residential treatment (RT) or intensive family …

Claiming The City: Co-Operation And Making The Deal In Urban Comprehensive Land Claims Negotiations In Canada, Christopher Alcantara, Jen Nelles

Political Science Faculty Publications

Since their introduction in 1973, comprehensive land claims (CLC) agreements have become important mechanisms for Aboriginal peoples to achieve their political, social, cultural, and economic goals. Although the literature on CLC negotiations is a rich and varied one, it has tended to ignore the role that municipal governments have on influencing negotiation outcomes. This lacuna is surprising since a number of treaty negotiations in the Yukon Territory and BC involve lands located in major municipalities. This paper develops a theoretical framework for understanding the influence that municipal governments can have on treaty negotiation outcomes. Using a case study of the …

Less emphasis, however, is placed in the working reports on style …

Perceptions Of Cohesion By Youth Sport Participants, Mark Eys, Todd Lougheed, Steven R. Bray, Albert V. Carron

Kinesiology and Physical Education Faculty Publications

Cohesion is an important small group variable within sport. However, the conceptualization and examination of cohesion have predominately been oriented toward adult populations. The purpose of the current study was to garner an understanding of what cohesion means to youth sport participants. Fifty-six team sport athletes (M_age = 15.63 ± 1.01 years) from two secondary schools took part in focus groups designed to understand participants’ perceptions of (a) the definition of cohesion and indicators of cohesive and noncohesive groups and (b) methods used to attempt to develop cohesion in their groups. Overall, the responses to part (a) yielded 10 …

Xenophobia, International Migration And Human Development, Jonathan Crush, Sujata Ramachandran

Southern African Migration Programme

In the continuing discussion on migration and development, the vulnerability of all migrant groups to exploitation and mistreatment in host countries has been highlighted along with an emphasis on protecting their rights. However, xenophobia has not yet received explicit attention although anti-migrant sentiments and practices are clearly on the rise even in receiving countries in developing regions. Despite gaps in existing empirical work, research and anecdotal evidence exposes pervasive forms of discrimination, hostility, and violence experienced by migrant communities, with the latter becoming easy scapegoats for various social problems in host countries. This study attempts to insert xenophobia in this …

Core-Offset Small-Core-Diameter Dispersion Compensation Fiber Interferometer And Its Applications In Fiber Sensors, Bo Dong, Da-Peng Zhou, Wing-Ki Liu, John W.Y. Lit

Physics and Computer Science Faculty Publications

We propose a core-offset small core diameter dispersion compensation fiber (DCF) interferometer and investigate its applications in fiber sensors. If the transverse force is applied to a short section of the DCF, there is almost no crosstalk on the transmission spectrum between the extinction ratio variation induced by the transverse force and the wavelength shift caused by the longitudinal strain or ambient temperature, which can be applied to measure both transverse and longitudinal strain, or both transverse strain and temperature, simultaneously. The proposed sensors have the advantages of low cost, simple and compact structure, and good reproducibility.
