Episode 5 - 2002: Vancouver's Book Club Choy(ce):
No full textThis episode of Vancouver Special we explore the year - 2002 - with a look back at the launch of Vancouver's first city-wide book club, One Book, One Vancouver.
CBC's sets the scene for 2002 and award-winning author Wayson Choy visits us in studio to talk about having his highly acclaimed bestseller selected as One Book, One Vancouver's inaugural title.
Popular with readers across the city and beyond, VPL's One Book, One Vancouver was created to promote and encourage a culture of reading and discussion in Vancouver. From 2002 to 2010 the program featured ten amazing books and dozens of imaginative programs – from author readings and neighbourhood walking tours to dinners in the heart of Stanley Park and boxing demonstrations in a regulation-size ring at Library Square – each designed to bring each book's theme's alive.
Wayson Choy's first novel, The Jade Peony, spent six months on The Globe and Mail's national bestseller list in 1995 and won the 1996 City of Vancouver Book Award. In 2002, it chosen as the inaugural book for One Book, One Vancouver.
And, VPL librarian Tim McMillan brings is back to bring it all together with some great reads you can find at your library.
The theme song is “North Wind” by Vancouver band Lakefield, from the album Sounds from the Treeline
Differences in acquisition of organic nitrogen in soils between bok choy and tomato
No full textSeedlings of bok choy and tomato were grown in soils with different N nitrogen [no N (-N), ammonium sulfate (AS), and cattle farmyard manure (CM)]. Comparison between soils treated with -N and CM indicated that the growth and N accumulation in bok choy were significantly enhanced by CM treatment, whereas no difference was found in tomato. In the rhizosphere soils, the highest protease activity was detected in CM treatment irrespective of species. Correlation analysis between rhizospheric protease activity and total N accumulation of plant treated with -N and CM showed a significant positive correlation only for bok choy. The determination of amino acid absorption rate in excised roots indicated that glycine was taken up at a significantly higher rate in bok choy than tomato. This study suggested that at least two possible factors affected the acquisition of organic N: rhizospheric protease activity and ability to absorb amino acids in roots
The effects of silicon nutrition on hydroponically grown lettuce, bok choy and basil
No full textConsidered a “stress nutrient”, silicon has been reported to provide beneficial effects to plants grown under biotic and abiotic stresses. The mechanisms considered are either an accumulation of absorbed silicon in the epidermal tissue, or an expression of metabolic or pathogenesis-mediated host defense responses. In the case of silicon nutrition, plants are considered silicon accumulators or non-accumulators. It is commonly accepted that accumulators can benefit from silicon, but studies have shown that non-accumulators can sometimes benefit from silicon nutrition when under stress on a case-by-case basis. The objective of this dissertation study was to reveal the potential beneficial effects of silicon nutrition on three hydroponically grown silicon non-accumulator vegetable species, lettuce, bok choy, and basil, representing the common leafy green families of Asteraceae, Brassicaceae, and Lamiaceae. None, low and high levels of silicon (0, 25 and 75 ppm) were added to the hydroponic nutrient solution. The plants were grown under temperature stresses (heat stress to lettuce and bok choy, and cold stress to basil), cut-and-grow-back stresses (lettuce, bok choy and basil), and biotic stresses (lettuce powdery mildew, simulated insect chewing on bok choy, and basil downy mildew). Plant growth, stress responses, and tissue nutrient analysis (including silicon) were evaluated. When grown under heat stress, silicon treatments failed to provide any beneficial effects for lettuce and bok choy. Basil grown under cold stress benefited from silicon treatments resulting in increased cold hardiness and improved survival rates after rates after a single frost event. Lettuce, bok choy, and basil grown under temperature stresses absorbed silicon in small quantities. The cut and grow back treatment did not result in silicon accumulation in lettuce, bok choy, and basil. The lettuce powdery mildew experiments failed due to the inability to establish sufficient disease pressure. The mechanical wounding treatment (representing insect chewing damage) in bok choy did not result in enhanced Si accumulation. For basil exposed to downy mildew, silicon treatments marginally increased the disease resistance without enhancing silicon accumulation. For most of the experiments, Si nutrition did not alter the content of other macro- and micro nutrients in both shoots and roots of lettuce, bok choy and basil. Future experiments are needed to evaluate the feasibility of using silicon as an effective BDM control agent for commercial growers. This dissertation research provided valuable information for understanding the physiology of silicon in non-accumulator plant species, and its potential beneficial effects for non-accumulator crops.Ph.D.Includes bibliographical reference

AUTOMATED STUDENT ACCOMMODATION BOOKING SYSTEM
No full textThe name of this project is Automated Student Accommodation Booking System
which is proposed by Mr. Choy Shao Keat. The main purpose of this project is to
develop a web-based system that can resolve current accommodation registration
issues that are facing by UTP students. Besides, it also aims to automate the manually
done task to reduce UTP Residential Village Management Team’s workload.
Evolution of technology has allowed digitalization of manually done activities
onto digital platform, thus save time and resources. In the past few years, many
universities have started to digitalize their student accommodation booking activities
by implementing online booking system. Hence, the literature review presents studies
that have been conducted in this area and similar systems that are available in other
universities. These studies allow the author to brainstorm ideas as well as enhancing
the features that are already available on these systems.
Furthermore, the methodology that has been chosen for this the development
of this system is Agile methodology. The reasons for choosing this methodology is to
achieve higher product quality and reduce risk of project failure. Scrum meetings and
sprint review in Agile methodology also provides a better visibility into project
performance. Despite that, this report aims to clarify and emphasize the importance of
the development of this project and how relevant it is to the UTP Students Community
as well as UTP Residential Village Management Team.
The system design is based on the existing accommodation booking system.
Besides that, the room booking concept that is available in hotel booking system will
be a reference to the proposed system. The proposed system aims to provide a set of
useful features to both students and Residential Village Management Team, at the
same time providing high level of user friendliness to all users.
Last but not least, the conclusion and future work will describe how this project
can sustain as well as explaining future development process that is going to be done

Hierarchical models for 2D presence/absence data having ambiguous zeroes: With a biogeographical case study on dingo behaviour
No full textThis dissertation is primarily an applied statistical modelling investigation, motivated by a case study comprising real data and real questions. Theoretical questions on modelling and computation of normalization constants arose from pursuit of these data analytic questions.\ud
\ud
The essence of the thesis can be described as follows.\ud
\ud
Consider binary data observed on a two-dimensional lattice. A common problem with such data is the ambiguity of zeroes recorded. These may represent zero response given some threshold (presence) or that the threshold has not been triggered (absence). Suppose that the researcher wishes to estimate the effects of covariates on the binary responses, whilst taking into account underlying spatial variation, which is itself of some interest. This situation arises in many contexts and the dingo, cypress and toad case studies described in the motivation chapter are examples of this.\ud
\ud
Two main approaches to modelling and inference are investigated in this thesis.\ud
\ud
The first is frequentist and based on generalized linear models, with spatial variation modelled by using a block structure or by smoothing the residuals spatially. The EM algorithm can be used to obtain point estimates, coupled with bootstrapping or asymptotic MLE estimates for standard errors.\ud
\ud
The second approach is Bayesian and based on a three- or four-tier hierarchical model, comprising a logistic regression with covariates for the data layer, a binary Markov Random field (MRF) for the underlying spatial process, and suitable priors for parameters in these main models. The three-parameter autologistic model is a particular MRF of interest. Markov chain Monte Carlo (MCMC) methods comprising hybrid Metropolis/Gibbs samplers is suitable for computation in this situation. Model performance can be gauged by MCMC diagnostics.\ud
\ud
Model choice can be assessed by incorporating another tier in the modelling hierarchy. This requires evaluation of a normalization constant, a notoriously difficult problem. Difficulty with estimating the normalization constant for the MRF can be overcome by using a path integral approach, although this is a highly computationally intensive method.\ud
\ud
Different methods of estimating ratios of normalization constants (N Cs) are investigated, including importance sampling Monte Carlo (ISMC), dependent Monte Carlo based on MCMC simulations (MCMC), and reverse logistic regression (RLR). I develop an idea present though not fully developed in the literature, and propose the Integrated mean canonical statistic (IMCS) method for estimating log NC ratios for binary MRFs. The IMCS method falls within the framework of the newly identified path sampling methods of Gelman & Meng (1998) and outperforms ISMC, MCMC and RLR. It also does not rely on simplifying assumptions, such as ignoring spatio-temporal dependence in the process. A thorough investigation is made of the application of IMCS to the three-parameter Autologistic model. This work introduces background computations required for the full implementation of the four-tier model in Chapter 7.\ud
\ud
Two different extensions of the three-tier model to a four-tier version are investigated. The first extension incorporates temporal dependence in the underlying spatio-temporal process. The second extensions allows the successes and failures in the data layer to depend on time. The MCMC computational method is extended to incorporate the extra layer. A major contribution of the thesis is the development of a fully Bayesian approach to inference for these hierarchical models for the first time.\ud

Unpacking clinical supervision in transitional and permanent supportive housing: scrutiny or support?
No full textBehavioral health organizations use clinical supervision to ensure professional development and practice quality. This qualitative study examined 35 service coordinators' perspectives on supervision in two distinct supportive housing program types (permanent and transitional). Thematic analysis of in-depth interviews yielded three contrast themes: support versus scrutiny, planned versus impromptu time, and Housing First versus Treatment First. Supervisory content and format resulted in differential perceptions of supervision, thereby influencing opportunities for learning. These findings suggest that unpacking discrete elements of supervision enactment in usual care settings can inform implementation of recovery-oriented practice.Peer reviewe
Sorting it out: eliciting consumer priorities in recovery
No full textObjective -- This study aims to understand participant priorities in their personal recovery journey and their perspectives of recovery domains.
Methods -- A card sort data gathering technique was employed to elicit priorities in recovery from consumers in supportive housing programs serving formerly homeless adults with severe mental illnesses in New York City. Participants (N=38) were asked to sort 12 cards printed with recovery domains in order of importance and describe the meaning attached to each domain.
Results -- Mental health (95%), physical health (89%), and housing (92%) were the domains most frequently included and prioritized in the top three rankings. Family (76%) and partner (74%) were also frequently included and endorsed as most important second only to mental health. Housing was prioritized yet rated most important less often (58%). Work, school, hobbies, program, friends and neighborhood were less frequently endorsed. ‘Card sort talk’ revealed critical understanding of participants’ priorities and their reasons for endorsing other domains less frequently.
Conclusions -- Most important to participants was regaining functional independence through improved mental and physical health and access to housing. With underlying principles of efficiency and empowerment, card sort is a promising engagement technique for providers to elicit consumer priorities in their own recovery.Peer reviewe
