Prevalence of iron-deficiency anaemia and low iron status and feeding practices among 9 months old infants in VancouverLwanga, Dorcas Namubiru 05 1900 (has links)
Iron-deficiency anaemia (IDA) is considered to be the most common nutritional
deficiency among infants and children worldwide. The consequences of IDA on the developing
central nervous system may be irreversible; these may include delayed mental and motor
development, and reduced school performance. Infants are particularly prone to develop IDA
if given foods low in iron content or foods that contain iron of low bioavailability. Infants from
low socioeconomic background and Asian, Black or Hispanic infants, are believed to be at
higher risk for IDA than White infants. There are no published studies on iron status in relation
to feeding history from British Columbia or other parts of Canada. The purpose of this study
was to determine the prevalence of IDA and low iron status in 9 month old infants in
Vancouver, British Columbia, and to determine which infants are at highest risk for IDA and
low iron status based on their feeding history, economic and ethnic background.
Infants who could participate in the study were identified from birth and death lists
provided by the Vancouver Public Health Department. Eligibility criteria were that the infant
was full term (gestational age a: 37-<42 weeks) with a birth weight of 2500-4500g and born
between January 1st, and March 2nd, 1993, or between June 4th and August 7th, 1993 to
parents resident in Vancouver, with an address to enable contact. Initial contact with parents
of all eligible infants (n = 1813) was made through a letter. A subsequent telephone call was
made to the parents to describe the study protocol and to arrange an appointment for parents
interested in participating with their infant. All the appointments were made to coincide with
the time when the infant would be 39 ± 1 weeks old. At the clinic appointment, blood samples
were collected from the infants, parents completed questionnaires regarding their family
background and their infant's nutritional history from birth to 9 months of age, and a visual recognition memory test (Fagan Test of Infant Intelligence) was administered to the infant.
Because many tests used to diagnose iron-deficiency anaemia lack specificity, several tests
were used in combination. IDA was classified as a Hgb ^101 g/L or Hgb <110 g/L with 2
or 3 abnormal biochemical tests from serum ferritin :S 10 //g/L, total iron binding capacity >
60 //mol/L, and zinc protoporphyrin >70 //mol ZPP/mol heme. Low iron status was classified
as a serum ferritin ^10 //g/L without iron-deficiency anaemia.
Four hundred and thirty four (434) 9 month old infants and their parents participated
in the study, representing 23.9% of all the eligible infants. The prevalence of IDA and low iron
status was 6.9% and 24.4%, respectively. A statistically significant association (p<0.0001)
was found between the infants' iron status and the duration of breast-feeding. IDA and low
iron status was found in 15.2% and 30.4%, respectively, in infants who had received breastmilk
as their main source of milk for more than 8 months. In contrast, the prevalence of IDA
and low iron status was 1.5% and 10.3%, respectively, among the group of infants who were
never breast-fed. Feeding low iron milk (cows' milk, low iron infant formula or goat's milk)
also showed a statistically significant (p < 0.05) association with the iron status of the infants.
No statistically significant association was found between iron status and the age of
introduction of specific solid foods (iron-fortified infant cereals, fruits, vegetables, legumes,
egg yolk, tofu, meat, chicken, or fish), or fruit juice.
No statistically significant association was found between the annual family income
and iron status of the infants, when considering either the entire group of infants, or the
infants from two parent households. However, a statistically significant association (p< 0.05)
was found between iron status and family income for the group of infants (n = 30) from one
parent families. Of note, only 7 of these infants were from families with an annual income of > $20,000. The low number of infants in this group limits the ability to predict the true
prevalence of IDA and low iron status, or the association with income in the single parent
families. No statistically significant association was found between the infants' iron status and
the mothers' level of education. A higher prevalence of iron-deficiency anaemia and low iron
status was found in infants of mothers born in Canada compared to infants of mothers not
born in Canada. The difference was statistically significant (p<0.05) suggesting a higher risk
for iron-deficiency anaemia and low iron status among infants' whose mother had been born
in Canada. No statistically significant association was found between the infants' iron status
and the number of years an immigrant mother had resided in Canada. Ethnic background as
reported by the mother was significantly associated (p<0.05) with the iron status of the
infants. Specifically, the prevalence of IDA was higher among infants of European and
Canadian parentage than among infants of East Indian and Chinese parentage. No statistically
significant differences were found between the scores on the visual recognition memory test
of the infants with iron-deficiency anaemia, low iron status or normal iron status.
In conclusion, the prevalence of iron-deficiency anaemia (6.9%) and low iron status
(24.4%) among otherwise healthy 9 month old infants who participated in this study suggests
the need to develop strategies for the prevention of iron-deficiency anaemia, or for early
detection and treatment. The results of this study show that the infants at highest risk for
iron-deficiency anaemia and low iron status in Vancouver, when defined by feeding history,
are infants with a history of breast-feeding as the main source of milk for more than 8
months, and infants bottle-fed low iron milk (cows' milk, goat's milk or low iron infant
formula). When defined by economic and ethnic background the infants at highest risk for
iron-deficiency anaemia are infants of Caucasian mothers (European or Canadian).

A case study of child care needs of Chinese immigrant families in Richmond, B.C.Chang, Shawne Chao Yun 11 1900 (has links)
Chinese children are viewed not only as the raison d'etre of their parents, but also as contributors to
their future well-being. The demands and expectations that shape the nurturing and education of
young Chinese children have developed on the basis of these beliefs. In Richmond B.C., a community
that has experienced a recent and rapid influx of Chinese immigrants, there has emerged an issue
regarding the nature of preschool education. On the one hand, immigrant Chinese parents prefer a
highly structured educational environment wherein English-as-a-Second language [ESL] instruction
is emphasized. This kind of pedagogical approach, it is believed, will foster their children's integration
into mainstream society. Early childhood educators and caregivers, on the other hand, favour an
exclusively play-based learning strategy, one devoid of formal training in grammar and phonetics.
These practitioners reject the reductionist approach advocated by parents in favour of what they view
as a more wholistic pedagogy. This issue is further exacerbated by cultural barriers: first, owing to
Confucian prescriptions against challenging authority, there exists a general reluctance on the part
of Chinese immigrants to confront school officials; second, communication between the two sides is
rendered difficult, if not impossible, by the language barrier. The purpose of this study is to foster
better understanding on the part of child care policy makers regarding the educational needs and
problems facing Chinese immigrant families residing in Richmond, B.C.
Literature relevant to early childhood development within a multicultural framework was reviewed
in this study. In particular, the development of ESL education for ethno-cultural preschoolers, the
philosophy of early childhood pedagogy, the result of quality child care and issues pertinent to
research terminology and techniques were closely examined. The literature reviewed was drawn
predominantly from Canadian and American sources. Their texts were served to illustrate differences in philosophical and practical perspectives regarding child care. Chinese sources were also examined
in order to explain cultural and ideological differences in the field of child care.
A profile of the interviewees was developed based on quantitative data collected during interviews
with 75 Chinese immigrant parents. The issues and problems identified in this study emerged from
qualitative interviews with Chinese parents and key informants, the latter consisting of, child care
practitioners, community workers, and educators.
This study found that problems experienced by Chinese parents regarding child care are similar to
those of Canadian parents. For instance, the lack of affordable and available quality child care are
common concerns. However, as discussed above, one significant difference identified is the Chinese
parents' emphasis on a pedagogical approach to early childhood education as opposed to the playbased
strategy advocated by preschool child care givers.
One other finding is that although most Chinese immigrant children can converse in English, few can
read or write basic English. While conversational ability is an integral part of learning a language,
reading and writing are more important with regard to the effective and efficient adoption of a second
language. This study concludes that preschool ESL training is a vital part of the solution for early and
successful integration of Chinese children into Canadian society.
How can planning address this problem? This study recommends that the Provincial Ministry of
Women's Equality which is responsible for child care together with the Federal Ministries of
Immigration, Human Resources and Health share information and develop programs that will provide immigrants with young children information related to the Canadian child care system. At the
provincial level, the key is to develop a community-based child care delivery system. Child care
policies and programs should be sufficiently flexible and sensitive to deal with immigrant child care
requirements. The promotion of culturally sensitized, community-based child care facilities and
programs should be developed by the Inter-Ministry Child Care Policy Coordination Committee
working closely with relevant ministries and communities. At the Municipal level, it is crucial to
establish and maintain up-to-date and accurate data bases to avoid ad hoc child care delivery systems
and polices. Coordination and cooperation of the Richmond Planning, Community Services and
Health Departments and local School District #38 would benefit not only immigrant children but all
children in the community.

Development cost levies : an analysis of park levies on commercial floorspace (in the city of Vancouver)Tully, Barbara 11 1900 (has links)
The use of Development Cost Levies is a relatively new mechanism by which
municipalities may charge development a share of costly new infrastructure. Their use is an
improvement upon the previous ad-hoc system of land use contracts. The equity of
Development Cost Levies is widely disputed, but this thesis finds that their use is fair and
justifiable when judged in the context of the unprecedented growth of the Lower Mainland.
The paper finds that Development Cost Levies are generally passed back to the landowners,
unless the market is inelastic, in which case they are passed forward to the purchaser.
The thesis specifically examines Development Cost Levies for parkland acquisition in
mixed-use neighbourhoods. Park acquisition levies in mixed-use neighbourhoods are
currently charged only to residential development in B.C. municipalities. This thesis
examines whether the usage of parks by employees warrants commercial development paying
a share of the parkland acquisition levies in mixed use neighbourhoods.
In order to determine if commercial development should pay a portion of the cost of
park acquisition, a park survey was conducted in an existing mixed-use area to determine
employee usage of parkspace. A literature search revealed no other park surveys which
examined employee and resident usage of parkspace in mixed-use neighbourhoods. The
survey found that employees generated 83% of the usage of parkspace in two mixed-use area
neighbourhood parks. The findings of the survey indicate that commercial development
should be paying a proportional share of development cost charges for parkland acquisition in
mixed-use neighbourhoods. This information was then applied to a recently upzoned area of
the City of Vancouver to illustrate a sample calculation of Development Cost Levies.

A film centre for Vancouver, British ColumbiaSchupp, John Alvin 11 1900 (has links)
This Thesis Project began as an attempt to explore the basic principles of Cinema: Light,
Time and Movement. As the project evolved I began to explore and develop various design
ideas. These included: the exploration of voyeuristic qualities within Cinema and Architec
tural ideas based on illusion and rhythm; cinema as a medium; and, geometric maipulations
and how different geometries might co-exist in an attempt to foster an image of diversity
while defocusing the stereotypical idea of school and institution.
The final product consisted of a 36,000 sq. ft. Film Centre, that housed a Film School, Indoor
and Outdoor Cinemas, the Vancouver Film Festival Offices, a multi-media Restaurant and
an Independant Film Studio.

Deja vu : an overview of 20th century adult education in British Columbia as reported by the mainstream pressStamm, Raimund Robert 11 1900 (has links)
Problem: With a few notable exceptions, the history of adult education in British Columbia has
received relatively little attention. What information there is, is often confined to somewhat
narrow time frames, locations, or topics. A general overview of the history of adult education in
British Columbia during the 20th century seems to be lacking. This study is a modest attempt to
begin adding voice to this important but largely overlooked area.
Conceptual Approach: The approach taken is one of historical review. The study, while to some
degree quantitative, is much more interested in the qualitative aspects of the material examined.
Newspapers, which the author suggests provide a unique historical record, serve as the sole
source of data.
Methodology: The B.C. Legislative Library Newspaper Index from 1900 -1999 is the source of
documents for this study. A thorough reading of all newspaper articles (550+), cited as being
related to adult education, was undertaken. Articles were grouped by decade and recorded.
Within the decades certain themes were identified and also recorded. Two specific themes
(lifelong learning and distance education) received special attention and were examined and
recorded separately.
Findings: There are a number of reoccurring themes that arise during the period examined.
Many of these themes have a direct correlation to issues facing adult education today. These
issues include, but are not limited to:
• lifelong learning
• distance education and related educational technology
• duplication of services
• libraries and adult education
• defining/purpose(s) adult education.
Since these and other issues are part of the current discourse about adult education, it seems
reasonable that lessons learned/not learned in the past not be forgotten. With the benefit of
historical hindsight, which includes sources that are not confined to potentially narrow interests,
adult educators may become better informed by considering these issues.

Transition in Tofino and Ucluelet : using indicators to become more sustainableBailey, Richard James 05 1900 (has links)
Many small communities in British Columbia are dramatically affected by economic transition.
This project discusses how two communities, Tofino and Ucluelet, have responded to transition
and how indicators can lead to a more sustainable future. While the communities share several
similar biophysical and geographical traits, key differences exist in their historical and socioeconomic
development. The communities, dependent on natural resources throughout their
history, have developed different responses to the challenges created by transition. This project
will discuss the transition experiences of Tofino and Ucluelet and detail how sustainable
development tools (indicators) can help the communities move towards a more sustainable future.
This project is guided by three key questions. First, the project considers the factors contributing
to structural economic transition in Tofino and Ucluelet within the context of British Columbia as
a whole. Secondly, the project examines how the communities of Tofino and Ucluelet have
addressed the challenges of economic transition and how are they planning for sustainability.
Finally, the project addresses how sustainability indicators can be used by the respective
communities to move towards a more sustainable future. This project drew on information from
the literature related to economic transition, sustainability indicators, and from interviews with
the Planners in Tofino and Ucluelet.
A process for how Tofino and Ucluelet could develop indicators is provided. Additionally, key
environmental, socio-economic, and tourism indicators are provided that address some of the
planning issues in the two communities. The project suggests that planners need to work with
communities to facilitate the development of indicators that support principles of sustainability.
Finally, it is suggested that a mechanism be developed to integrate indicators into formal planning
practice.

The effect of coarse woody debris on site productivity of some forest sites in southwestern British ColumbiaKayahara, Gordon John 11 1900 (has links)
I explored the importance of decaying wood to survival and growth of trees in south coastal
British Columbia, and the effect of decaying wood on the intensity of podzolization on mesic
sites.
A field pot study was carried out in both high light and low light conditions using woody and
non-woody forest floor materials. After two growing seasons, Pseudotsuga menziesii, Tsuga
heterophylla, and Abies amabilis seedlings growing in clearcuts had greater survival and growth
in the non-woody substrate; however, in the understory, the effect was much less. The
proliferation of western hemlock roots was used as an indicator of the value of decaying wood to
trees. In both greenhouse trials (using seed sown on a series of planting pots with each half filled
with either a woody substrate or a non-woody substrate), and in field sampling of woody and
non-woody substrates in mature stands, the non-woody substrate had a larger density of fine and
very fine roots compared to the woody substrates or mineral soil.
Ten litres of concentrated solutions of non-woody humus substrate and woody substrates
were leached through soil columns. Both the non-woody and woody solutions had similar mean
pH but significantly different chemical properties. The non-woody solution leachate had greater
net average output of dissolved organic C, Fe, and Mn. The mineral soil treated with the nonwoody
solution had significantly greater concentrations of total N and pyrophosphate-extractable
Fe. In the field, forest floor and soil samples were compared between pedons having large
accumulation of decaying wood and pedons with non-woody humus forms. Despite large and
significant differences in chemical properties between the two substrates, there were generally no
significant differences between the chemical properties of the soils directly under these
substrates. In most cases, the results of (3-analyses showed that the means were not
pedologically different. Additionally, 18 pairs of zero tension plate lysimeters were installed
under the two substrates. The lysimeter solutions showed no significant differences.
I concluded that coarse woody debris appears not to have either a positive effect of increased
productivity of trees or a negative effect of increased intensity of podzolization.

A decision making model of child abuse reportingBeck, Kirk A. 05 1900 (has links)
This study applied Ethnographic Decision Tree Modeling (Gladwin, 1989) to the field of
child abuse reporting to investigate the factors that influence decisions to report possible
child abuse. Participants were licensed psychologists in the lower mainland of British
Columbia. Using ethnographic interviews, participants were asked to discuss a recent
case in which they reported possible child abuse and the factors that were influential in
their decision making. Based on the data from 34 cases, six factors were identified: (1)
Were there any signs of or risk factors for child abuse or neglect? (2) Did the signs or risk
factors meet your threshold to report as you understand the law? (3) Was there some other
value to report other than a legal one? (4) Were you concerned that reporting would cause
harm? (5) Were you able to minimize the harm that would result from reporting? and (6)
Did the reasons to report outweigh the reasons to not report? These six factors were
presented in a decision tree to illustrate the relationship between factors and decision
outcome. This preliminary group model was then tested using the case experiences of a
separate yet similar group of registered psychologists in British Columbia. Results found
that the preliminary model accurately predicted the reporting outcome of 93% (33 of 36)
of the cases in the new sample. Errors in the model were identified, and suggestions were
made to improve its predictive ability. The results are evaluated in light of the decision
tree produced. Implications for theory building, naturalistic inquiry, clinical practice,
policy, and future research are discussed.
