Connecting British Columbia (Canada) school libraries and student achievement: A comparison of higher and lower performing schools with similar overall funding

Research over time has established associations between components of the school library and student achievement. This study was designed to investigate these associations in schools in British Columbia (Canada) where the government provides equitable funding of public schools while allowing individual school districts and schools to determine individual funding priorities. Findings replicated what numerous previous studies have shown: higher student standardized test scores were associated with a school library that is more accessible, better funded, professionally staffed, managed, stocked, integrated and used. Findings moreover pointed to higher student achievement in those schools where greater resources, from the same limited allocation were assigned to school libraries. Results of this study are of practical interest to policy makers, school and library administrators, and educators with a vested interest in student achievement and the future of school libraries.

HCI for peace: from idealism to concrete steps

This panel will contribute diverse perspectives on the use of computer technology to promote peace and prevent armed conflict. These perspectives include: the use of social media to promote democracy and citizen participation, the role of computers in helping people communicate across division lines in zones of conflict, how persuasive technology can promote peace, and how interaction design can play a role in post-conflict reconciliation

Estimation of genetic parameters for height using spatial analysis in Tsuga heterophylla full-sibling family trials in British Columbia

Non-spatial and spatial analyses were carried out to study the effects on genetic parameters in ten-year height growth data across two series of 10 large second-generation full-sib progeny trials of western hemlock [Tsuga heterophylla (Raf.) Sarg.] in British Columbia. To account for different and complex patterns of environmental heterogeneity, spatial single trial analyses were conducted using an individual-tree mixed model with a two-dimensional smoothing surface with tensor product of B-spline bases. The spatial single trial analysis, in all cases, showed sizeable lower Deviance Information Criterion values relative to the non-spatial analysis. Also, fitting a surface displayed a consistent reduction in the posterior mean as well as a decrease in the standard deviations of error variance, no appreciable changes in the additive variance, an increase of individual narrow-sense heritability, and accuracy of breeding values. The tensor product of cubic basis functions of B-spline based on a mixed model framework does provide a useful new alternative to model different and complex patterns of spatial variability within sites in forest genetic trials. Individual narrow-sense heritabilities estimates from the spatial single trial analyses were low (average of 0.06), but typical of this species. Estimated dominance relative to additive variances were unstable across sites (from 0.00 to 1.59). The implications of these estimations will be discussed with respect to the western hemlock genetic improvement program in British Columbia.Fil: Cappa, Eduardo Pablo.

Spending time with money: from shared values to social connectivity

This article has been made available through the Brunel Open Access Publishing Fund.There is a rapidly growing momentum driving the development of mobile payment systems for co-present interactions, using near-field communication on smartphones and contactless payment systems. The design (and marketing) imperative for this is to enable faster, simpler, effortless and secure transactions, yet our evidence shows that this focus on reducing transactional friction may ignore other important features around making payments. We draw from empirical data to consider user interactions around financial exchanges made on mobile phones. Our findings examine how the practices around making payments support people in making connections, to other people, to their communities, to the places they move through, to their environment, and to what they consume. While these social and community bonds shape the kinds of interactions that become possible, they also shape how users feel about, and act on, the values that they hold with their co-users. We draw implications for future payment systems that make use of community connections, build trust, leverage transactional latency, and generate opportunities for rich social interactions

Disability Related Sources of Income and Expenses: An Examination Among the Elderly in Canada

The primary purpose of this paper is to examine disability-related sources of income and expenses among high and low income older Canadians. Specifically, the paper attempts to answer three questions: Do low and high income seniors experience disability equally? Do low and high income seniors incur equal disability- related non-reimbursed expenses? And, Do low and high income seniors receive equal disability-related pensions and tax credits? The analysis is based on the Health and Activity Limitation Surveys of 1986 and 1991. Both surveys were cross-sectional, designed to gather information on disabilities and their impact on daily living. Among the seniors (those 65 and over), between 10.3% (men in 1986) and 23.2% (women in 1991) were classified as low income and about 40% reporting having at least one disability, compared to one-quarter of women and men of all ages. The analysis indicates that low income seniors are disadvantaged in that they experience more disability, incur more non-reimbursed expenses, and receive less in terms of disability- related pensions and credits than do high income seniors. It thus appears that interventions should be policy based rather than individual based.elderly; disability; income

PORK MARKET DEVELOPMENT RESEARCH PROJECT: MARKET POTENTIAL FOR ALBERTA'S PORK IN SELECTED U.S. MARKETS

The ethnic Asian market in Washington and Oregon constitutes a sizable niche market for fresh Canadian pork. Since California possesses a large population segment that originates from Asia, the characteristics of the ethnic Asian-origin market in the northern part of that State are also of interest since this may also be a potential niche market for Canadian pork. The objectives of the first part of this study are to evaluate the Asian ethnic markets for fresh pork in the United States Pacific Northwest and Vancouver. In the second part of the project the assessment of the market for fresh pork by Asian-origin consumers was extended to San Francisco. In this extension, a detailed assessment was also made of the product preferences for fresh pork by Asian-origin consumers in San Francisco and the behaviour patterns associated with store choices of these fresh pork consumers. Asian retailers and distributors in Vancouver, Seattle and Portland were surveyed by direct interview during November and December 1996. The survey applied semantic differential scaling questions, open-ended questions and a stated preference task, a conjoint methodology, to examine pork retailer's and distributor's perceptions of fresh pork produced in Western Canada and in the Midwest United States. Personal interviews with wholesalers and retailers were also applied in the San Francisco market survey which was conducted in 1998. Two consumer surveys were also conducted in San Francisco in 1998, directed at Asian-origin consumers of fresh pork. The structure of the market for fresh pork represented by retailers catering to Asian consumers in Vancouver differs from that in Seattle and Portland. The "Asian market" in Vancouver is dominated by many small shops that deal directly with packers. The small shops in Seattle and Portland deal with distributors and wholesalers. Distributors play a small role in Vancouver's retail market. Asian retailers in Seattle deal with a variety of suppliers, including both packers and distributors. In Portland, retailers catering to Asian consumers trade mainly with distributors and a local packer-wholesaler. In San Francisco, Asian stores and butcher shops prefer to obtain pork through smaller joggers, while American style supermarket retailers catering to the Asian consumers purchase pork directly from meat packing companies; fresh pork is sold in different ways in the different types of stores catering to Asian consumers that are found in these markets. The first survey found that Western Canadian pork enjoys an image of superior quality amongst retailers and distributors in Seattle's ethnic Asian market. Asian retailers in Portland are less familiar with Western Canadian pork and did not regard it as highly as did retailers in Seattle. However, distributors in Portland are more familiar with Western Canadian pork and consider it to be superior to Midwest United States pork in terms of overall quality, meat colour and fat trim. In both these markets, Western Canadian pork is generally considered to be expensive. These results are not statistically significant, however they are of economic relevance since most of the major players in the segment were interviewed. Little knowledge of Western Canadian pork was evidenced by retailers or consumers in this market segment in San Francisco. Western Canadian pork presently enjoys a reputation for superior quality amongst the retailers that specialize in sales to Asian consumers in Seattle and Portland. However it is also clear that many members of the trade lack information or experience with Canadian pork. Consequently, there is an opportunity for Canadian processors to maintain or increase market share through more education and promotion to this market segment. The 1998 survey of Asian-origin consumers of fresh pork in San Francisco focused on two aspects: preferences for fresh pork attributes and choice of store for fresh pork purchases. An intercept survey method was chosen to select and interview consumer respondents. Some 40% of the 196 respondents to the store choice survey purchase most of their fresh pork from American style supermarkets, 33% purchase mostly from small Asian stores, 24% from large Asian stores, and the rest from butcher shops. The most popular cut of pork purchased by Asian consumers is loins, followed by pork shoulders and butts, then pork leg, bellies, hock, and offal. The analysis indicated that socio-economic and demographic factors, as well as store attributes, significantly affect Asian consumers' store and product choices. The analysis of the ranking of selected attributes of fresh pork by Asian-origin consumers in San Francisco, California showed that freshness is ranked as the most important attribute, followed by the attributes of the color of meat, lowness in fat, and the whiteness of fat. The attributes of price, freedom from chemicals, and being USDA labelled were also ranked to be of importance. The attributes of little or least importance were knowing that pork came from the US, customized pork cuts, the variety of pork cuts, packaged pork, vacuum packed pork and seasoned and prepared pork. Empirical results from an ordered probit model postulated to explain respondents' rankings of attributes indicate that particular demographic and socio-economic characteristics of Asian-origin consumers influenced the importance rankings for the pork attributes that were identified to be important. For example, Chinese origin consumers were appreciably more sensitive to pork price than were other Asian-origin groups. One facet of the findings is that marketing strategies should not treat Asian-origin consumers as a single homogenous niche group in marketing since there are identifiable sub-groups of these consumers with specific attitudes and preferences. The importance placed on different attributes by particular ethnic subgroups, and their different preferences for stores at which fresh pork is purchased, provides useful information on which to develop strategies to target market development activities at the Asian-origin ethnic subgroups.Marketing, International Relations/Trade,

Farmland Conservation in The Netherlands and British Columbia, Canada: A Comparative Analysis Using GIS-based Hedonic Pricing Models

As a result of urban development farmland in many countries is under pressure. Reasons to preserve farmland are related to cultural heritage, food safety, open space, the environment, but also slowing and restricting development is a reason. To protect farmland countries use different land use policies. This paper will look specifically at two jurisdictions: The Netherlands and a particularly rich farming area in British Columbia, Canada. For these areas we will investigate how the institutions and laws present in these jurisdictions contribute to agricultural land preservation. We will analyse farmland values in a GIS-based hedonic pricing framework to answer this question. This combination enables us to analyse direct impacts of laws and regulations within the hedonic pricing framework. Moreover, we can use farm values to analyse farm survivability, and the level of speculation on farmland in the urban-rural fringe, where farmland is under urban pressure.Hedonic pricing models, zoning policies, Geographical Information System, agricultural land values at the urban fringe

Incentive-based approaches to sustainable fisheries (now replaced by EEN0508)

Using examples from more than a dozen fisheries, we highlight the failures of ‘command control’ management and show that approaches that empower fishers with the incentives and the mandate to be co-custodians of the marine environment can promote sustainability. Evidence is provided that where harvesters share well-defined management responsibilities over fish, and experience both the pain of overexploitation and the gains from conservation, they are much more likely to protect fish stocks and habitat. The key insight is that to maintain marine ecosystems for present and future generations, fishing incentives must be compatible with long-term goals of sustainability.incentives, sustainability, rights, fisheries management

Dividing population genetic distance data with the software Partitioning Optimization with Restricted Growth Strings (PORGS): an application for Chinook salmon (Oncorhynchus tshawytscha), Vancouver Island, British Columbia

A new method of finding the optimal group membership and number of groupings to partition population genetic distance data is presented. The software program Partitioning Optimization with Restricted Growth Strings (PORGS), visits all possible set partitions and deems acceptable partitions to be those that reduce mean intracluster distance. The optimal number of groups is determined with the gap statistic which compares PORGS results with a reference distribution. The PORGS method was validated by a simulated data set with a known distribution. For efficiency, where values of n were larger, restricted growth strings (RGS) were used to bipartition populations during a nested search (bi-PORGS). Bi-PORGS was applied to a set of genetic data from 18 Chinook salmon (Oncorhynchus tshawytscha) populations from the west coast of Vancouver Island. The optimal grouping of these populations corresponded to four geographic locations: 1) Quatsino Sound, 2) Nootka Sound, 3) Clayoquot +Barkley sounds, and 4) southwest Vancouver Island. However, assignment of populations to groups did not strictly reflect the geographical divisions; fish of Barkley Sound origin that had strayed into the Gold River and close genetic similarity between transferred and donor populations meant groupings crossed geographic boundaries. Overall, stock structure determined by this partitioning method was similar to that determined by the unweighted pair-group method with arithmetic averages (UPGMA), an agglomerative clustering algorithm
