Harmony Landfill is a former industrial waste disposal site located adjacent to Harmony Creek in Oshawa, Ontario, Canada. During active disposal, from 1957 until 1980, approximately 1 million tonnes of waste were land-filled at the site. Although past environmental monitoring had indicated localized contamination of ground and surface waters, the current level of impact remained unclear. In order to determine the potential of Harmony Landfill leachate to affect aquatic organisms in Harmony Creek, chemical analysis of field samples and laboratory toxicity testing were performed. Chemical analysis was completed on water samples from Harmony Creek and surface leachate samples collected seasonally at Harmony Landfill. Toxicity tests were conducted using the model freshwater invertebrate Green Hydra (Hydra viridissima). Hydra were pulse-exposed for 24 hours to varying concentrations (0%, 3.2%, 10%, 32%, 100%) of monthly field-collected leachate samples diluted with laboratory water. Population growth, Hydra morphology and survival were recorded daily for 7 days. Results showed that creek waters generally had comparable analyte levels upstream and downstream of Harmony Landfill. Leachate samples contained iron, manganese and zinc at levels which may be toxic to aquatic invertebrates. Population growth was significantly inhibited compared to lab water (0%) controls at the 100% leachate concentration in December 2008 and July 2009. Hydra morphology (32% and 100%) and survival (100%) were also affected by the December 2008 leachate. Findings indicate that leaching is occurring at Harmony Landfill and that the leachate sampled and tested during this research program had the potential to negatively affect Green Hydra (Hydra viridissima). / UOIT

The study contributes to the growing literature on the role of social economy enterprises on rural vitality, by examining the relationship between credit union activity and community population growth in rural Canada. A preliminary qualitative inquiry indicated that while most of the business policies and practices of a chartered bank and a credit union are similar, a credit union, in addition, extended non-traditional lending to their clients in the form of micro-lending and also participated actively in community development lending. Following the preliminary qualitative investigation, the impact of credit unions was examined using spatial regressions models in seven provinces in Canada using data at Consolidated Census Subdivisions (CCSs) level data to represent communities. Motivated by the potential role of credit unions as community based financial institutions, the quantitative analysis modeled credit unions as potentially reducing transactions costs for local businesses.<p> Regression results indicated that the presence of credit unions was statistically significant and positive in our most parsimonious models including only natural amenity factors, agglomeration measures and other social measures as explanatory variables. However, in the full model with economic variables added the credit union dummy lost its statistical significance. A possible interpretation is that the credit union dummy is an inadequate representation of credit union activity. More complete, high quality, quantitative data to reflect their activities in the community may have produced different results.<p> Recent credit union mergers are designed to increase their capacity and efficiency in providing services to their members. However, these new trends could aggravate the principal-agent problems. As credit unions become more bank-like though mergers, individual branches may lose their links with their local communities and their ability to perform their traditional functions.

This study investigates the contemporary urbanization process of sub-Saharan Africa. The region is predicted to experience a surge in urban population growth the forthcoming decades, yet why and how this is happening is not very clear. Theory often considers urbanization to be a part of a modernization process where people migrate from rural areas to urban. But depictions of reality suggest that rural-to-urban migration might be less significant than previously thought, and neither is it given that urbanization causes prosperity in sub-Saharan Africa. This thesis tries to complement the gap of knowledge regarding the mechanisms of urbanization in sub-Saharan Africa. Statistical data is organized and assembled by using the structured, focused comparison method and then analyzed in order to create an understanding of urbanization and urban population growth in this particular region. The result of this study suggests that the mechanisms for urban population growth change over time. Urban population growth is often thought to be driven by rural-to-urban migration. However, nowadays there is a correlation between urban population growth and population increase, which did not exist a couple of decades ago. It is clear that urbanized countries are, typically, more advanced regarding economic growth, but it is unsure whether this factor affects socio-economic development. The findings underscore the vast complexity of urbanization and urban population growth, as well as the heterogeneity of sub-Saharan Africa. Yet there is potential for a new theoretical framework that can provide explanations to the processes sub-Saharan Africa is expected to undergo.

As cities across the world have grown and continue to grow in many ways and for many reasons, it is anticipated that the growth of population will come from all over the world. In turn, it will influence on our urban environment economically, socially, culturally, and ecologically. Like other cities, London is making a plan -creating 326,000 new homes and 776,000 jobs - to tackle issues of the city. A series of new emerging developments across London will contribute to the changing face of the city. A lot of interventions spreading through the city are focused on the economic forces and to take advantages of real estate of London by projecting offices, apartment which is mostly market-housing, and hotels. They swept away existing contexts and replaced with higher density buildings obtaining large profits, building high rise, filling gaps between buildings with gated car parks on the ground floors, and building over open spaces. Ground floors remain blind, and tall office blocks make the overshadowed open square inhospitable and wind turbulence. Most initiatives do not seem to contribute to urban life, but may possibly become the slums of tomorrow. Now, it is time to think about how to make sense of an environment which is safe, pleasant and healthy with a sense of identity, and how to contribute to neighborhoods, visitors and new comers. In dense inner city area, since place is an invitation where neighborhood meets city, urban design must meet needs of commuters, visitors, travelers, and residents equally by combining place, amenity, and movement. Therefore, this study is to investigate ‘How city’s agenda combine with, and support local neighborhood needs’, and to redefine the quality of city life through qualities of comfort, accessibility, amenity, education, experience, and nature. / text

This thesis presents the comparison of role played by economic freedom and education in making population growth beneficial for economy. In order to assess this relationship, four groups of countries have been selected based on EFW index. Cross-section regression has been performed including 92 countries for years 2005 and 2010. Comparisons have also been presented in graphical analysis. Moreover, correlations among variables have also been studied. It has been concluded that education matters the most in turning population growth to an asset.

In this thesis, called a simulation model of population growth, there was created the simulation model of a population growth in the Czech Republic to the year 2052. First there was constructed the projection through the component method used in demography. Deterministic values obtained by this method are then used in the simulation analysis. In the simulation analysis there was conducted an experiment with three variables which influence the population growth (the fertility, life expectancy/the coefficient of the decline of the probability of the death/ and the migration balance). With the support of the Crystal Ball, supporting program for Excel, which provides the possibility of the simulations, there was determined the stochastic character of the three variables. There are created the low, medium and high variant of the projections, as well as three other possible variants of population growth that might occur. These variations are called economic crisis, friendly migration policy and restrictive migration policy.

Background Nigeria, with a population growth rate (2000-2005) of 2.5% and with 5% of the total population aged 60 years and above, has the potential for a rapid growth rate of the older population in coming years.1 The implication of this in a country with large population as reported by the National Population Census 2006, limited number of health care professionals and care homes, is difficulty in meeting the various needs of the elderly, hence, the importance of identifying the palliative care needs of the elderly. Aim The study was set out to assess the palliative care needs of and provision of care to elderly patients seen in the selected clinics of the University College Hospital, Ibadan, Oyo state, Nigeria. Objectives 1. To describe characteristics of elderly patients seen in the selected clinics. 2. To explore the current use of the hospital palliative care team in the care of geriatric patient. 3. To explore the current use of the hospital palliative care team in the care of geriatric patient. Methods A descriptive cross-sectional study was conducted over a 3-month period using an interviewer administered questionnaire after full consent was given by participants. The questionnaire was a combination of the Africa Palliative Care Outcome Scale (APCA-POS), the Edmonton Symptom Assessment Scale (ESAS) and Hope Spiritual Assessment Tool. Demographic information regarding gender, age, nationality, abode and referral to the Care Centre was obtained. Scaled questions from selected tools were ticked with respect to physical, psychosocial and spiritual needs and expectations of palliative care. The validated data collection tools (APCA-POS, ESAS, HOPE) were used in the questionnaire. Ethical approval was obtained from the relevant organizations. Data was analysed using IBM SPSS statistics 21. Results 424 participants completed the questionnaire and most patients (330; 77.8%) were recruited from the geriatric wards with a 2:1 female to male ratio. Most participants fell in the 60 -69 year-old age group. The most common symptom was pain in 240 patients with moderate pain in single or multiple areas. A high percentage (45.8%) were moderately worried about their disease condition and only 66 out of 422 freely discussed this feeling with their family members. Other symptoms observed were nausea, vomiting, constipation and loss of appetite. Conclusion The study showed the palliative care needs of the elderly and calls for collaboration between the palliative care team and the physicians in the geriatric unit for better management of the needs of the elderly.
