    Abstract:
    The growing interest in the long-term performance of pile foundations and their ability to resist the negative effects of water exposure and aggressive soils has led to considering non-corrosive materials such as fibre-reinforced polymer (FRP). The most common applications are light-bearing structures in waterfront environments, while applications for larger structures have not been widely accepted in industry due to the lack of long-term records and design guidelines available. Previous research has primarily focused on the load transfer of concrete-filled FRP tubes—making it difficult to quantify the performance of FRP as a piling material on its own. In this study, a numerical model using the finite element method was developed to simulate small-scale load tests of hollow carbon-fibre reinforced polymer (CFRP) and glass-fibre reinforced polymer (GFRP) piles in soft clay. Verification of the model was attained using results from axial and lateral load tests on small-scale hollow CFRP and GFRP piles and pile-soil interaction was modelled using experimental data from interface shear tests conducted at Carleton University. A parametric analysis was performed to investigate and determine the key factors that influence the axial and lateral load response of hollow FRP piles. The findings of this research indicate that the number of FRP layers impacts loading behaviour significantly, while inner tube soil height has a reasonable influence on axial load response and fibre orientation has a minor effect under lateral load conditions.

    Abstract:
    Peer-to-peer networks are well known for file sharing between multiple computers. They establish virtual tunnels between computers to transfer data, but NATs makes it harder. A NAT, Network Address Translation, is a process which transforms private IP addresses, such as 192.168.2.1, into public addresses, such as 203.0.113.40. The idea is that multiple private addresses can hide behind a single public address and thus virtually enlarge the number of allocable public IP addresses. When an application in the local network establishes a connection to Internet, the packet passes through the NAT which adjusts the IP header and maps an external port to the computer which sent the request. When packets are received from the Internet by the NAT, they are forwarded to the internal host which is mapped to the port on which the packet was received, or dropped if no mapping exists. In this paper, we will introduce you to NAT and P2P, we will discuss the numerous ways NATs use to translate private IP addresses into public ones, we will discuss known techniques used to fix the problem and we will also present how popular peer-to-peer programs bypass NATs. This paper is written so anybody with a reasonable knowledge of networking would grasp the essentials. It is important to keep in mind that the traversal methods presented in this document work for UDP and TCP and require no manual configuration of the Network Address Translator itself.

  • Information Management in the Canadian Federal Government: Principles, Practices and the Role of Information Professionals

    Resource Type:

    Stricker, Ulla de and Jordan, Isla
    Abstract:
    Information management (IM) in the Canadian public sector is a complex area involving many professions such as librarians, archivists, records managers and information technology professionals. This exploratory study looks at the literature and experiential (qualitative) evidence from IM professionals in order to paint a picture of information management principles and practice in the Canadian federal government. Personal interviews were conducted with 20 librarians, information managers, records managers and other information professionals. Responses indicated that although the public sector has made tremendous strides in IM, there is often a gap between IM policy and practice as shown by inconsistencies and confusion in day to day operations compounded by the decimation of federal libraries (which are repositories of external as well as government information). The study also looks at roles of librarians and other IM professionals now and in the future. These professionals are well positioned to help close the gap between information policy and practice, moving forward toward more coordinated and integrated practices in information management as well as making information accessible and usable for their clients. Such functions aid the Canadian public sector in becoming a more effective knowledge organization.

    Abstract:
    Canada’s coal-fired electricity regulations were published in 2012 and were the first federal regulations targeting greenhouse gas (GHG) emissions from stationary sources. They have since been strengthened. This case study tells the policy story of how the regulations came about, and how in the space of 18 months the government’s regulatory approach evolved from one based on emissions intensity, to cap-and-trade, to capital stock turnover. It also tells the technical story of how a simple regulation based on the length of time a facility has to operate can still build in elements of trading and other flexibilities. It ends with some observations around lessons learned.

    Abstract:
    Canadians living in rural communities are diverse, with individual communities defined by unique strengths and challenges that impact their health needs. Understanding rural health needs is a complex undertaking, with many challenges pertaining to engagement, research, and policy development. In order to address these challenges, it is imperative to understand the unique characteristics of rural communities as well as to ensure that the voices of rural and remote communities are prioritized in the development and implementation of rural health research programs and policy. Effective community engagement is essential in order to establish rural-normative programs and policies to improve the health of individuals living in rural, remote, and northern communities. This report was informed by a community engagement workshop held in Golden Lake, Ontario in October 2019. Workshop attendees were comprised of residents from communities within the Madawaska Valley, community health care professionals, students and researchers from Carleton University in Ottawa, Ontario, and international researchers from Australia, Sweden, and Austria. The themes identified throughout the workshop included community strengths and initiatives that are working well, challenges and concerns faced by the community in the context of health, and suggestions to build on strengths and address challenges to improve the health of residents in the Madawaska Valley.

    Abstract:
    The small size coupled with remoteness of rural communities in Canada, Australia, and Sweden introduce challenges in accessing sufficient health services (1-3). The sparse health services in rural areas impose “the tyranny of distance” on rural and remote populations, necessitating lengthy travel times to receive care. Despite the increased challenges rural communities face, a dearth of research on rural health persists, particularly rural youth health (4,5). A broad scoping review was undertaken to identify literature regarding rural youth health in Canada, Australia, and Sweden. The studies were coded according to population focus, health focus, access, and general. The scoping review produced the Rural Youth Health Scoping Review Database, which provides an overview of the available research on rural youth health.

    Abstract:
    Rural and remote communities in both Australia and Canada have a higher burden of mental illness relative to their urban counterparts. Suicide rates, particularly, are higher across all age groups among men in rural communities as compared to metropolitan areas. Mental health issues are especially present in younger populations within these communities. Additionally, rural and remote communities tend to have higher proportions of Indigenous origin individuals, who face additional challenges and service barriers. Rural and remote communities often encounter significant barriers to accessing mental health care. Individuals from these communities may be serviced solely by general health care providers that are not trained in mental health treatment. Travelling away from the community to alleviate this issue only further hinders accessibility as these individuals must travel larger distances to access specialized health services. When services are accessed, those from rural and remote communities are met with longer wait times than their urban counterparts. With no specialized treatment within the rural or remote community and inaccessible treatment outside the community, mental health care must shift to informal caregivers and the community as a whole. Rural and remote communities are often not trained in mental health care. Interventions to address rural and remote youth mental health are needed to equip communities with the tools and skills to overcome access barriers and support community members. A review of recent literature related to rural and remote youth mental health interventions was conducted. The aim of the review is to characterize these mental health interventions in Australia and Canada and examine how they relate to youth.
