Social-Emotional Functioning In Ethnic Minority Infants and Toddlers: A Cumulative Risk Factor Perspective

Lai, Betty 01 January 2008 (has links)
This study examined the influence of contextual risk factors and parental depression on the social-emotional functioning of very young children. Ninety-four young children were recruited as part of a larger ongoing research project recruiting caregivers and children from Early Head Start programs in South Florida. Children ranged in age from 12 to 36 months and included 65 girls and 29 boys. There were 94 caregivers in the current study: 91 mothers, 2 fathers, and 1 foster mother. Caregivers were diverse in terms of age, ranging from 19 to 42 years of age (M = 27.31, SD = 5.75), ethnicity (84% African- or Caribbean-American, 14.9% Hispanic/Latino, and 1.1% Mixed/Other), and in number of years of school completed, ranging from 1 to 16 years (M = 12.02, SD = 1.91). The current study employed a cumulative risk factor perspective in examining the social-emotional functioning of infants and toddlers. Specifically, the current study tested both a threshold model and a linear model of cumulative risk. Study measures included a background questionnaire, a measure of parental depression, a measure of parenting stress, a measure of child exposure to violence, and a measure of traumatic life events in a child?s life. Further analyses examined ethnicity as a moderator of the relationship between cumulative risk and difficulties with social-emotional functioning. Results showed a significant linear relationship between cumulative risk and social-emotional functioning. However, ethnicity did not moderate this relationship. When individual risk factors were examined post hoc, parental depression, stressful parent-child interactions, having a child with special needs, and community violence were shown to significantly predict difficulties with social-emotional functioning among very young children. These data have important implications for prevention and intervention efforts.

A cumulative effects approach to wetland mitigation

Nielsen, Jesse Lee 30 March 2010
Wetlands are among the most ecologically productive lands in the world, but every year they continue to be lost due to increasing pressures from agriculture, industrial development, urbanization and the lack of effective mitigation to deal with such pressures. Despite environmental assessment processes, policies, and regulations to ensure the mitigation of affected wetlands, wetlands continue to experience a loss in areal extent, but more importantly, a functional net-loss. This is attributed, in large part, to the lack of incorporating cumulative effects principles into project-based wetland impact assessment and mitigation. The majority of activities that affect wetlands are either assessed at the screening level, where cumulative effects are rarely considered, or are deemed insignificant and do not trigger any formal environmental assessment process. As a result, the mitigation of cumulative effects on wetlands is often insufficient or completely lacking in development planning and decision-making. Part of the challenge is that there currently does not exist methodological guidance as to how to identify wetland cumulative effects and corresponding mitigation needs early in the project design process. This research presents a methodological framework and guidance for the integration of cumulative effects in decision-making for project-based, wetland impact mitigation. The framework provides a means for the early indication, assessment, and mitigation of the potential cumulative effects of project developments on the wetland environment, with the objective of ensuring a no-net-loss of wetland functions.

The Financial Effects of Going Public on Football Clubs

Low, Gareth, Karlsson, Fredrik January 2015 (has links)
In this thesis we analyze the financial performance of Football clubs following an initial public offering (IPO). We conduct several analyses using time series stock data with a focus on finding evidence of long-run underperformance and IPO over/underpricing. To this end, we estimate cumulative abnormal returns (CAR) and Jensen’s Alpha. We also analyze coefficients such as beta to describe the volatility and the link football clubs’ stocks have to the general market. We look at historical events that may have affected the movement of stock prices and confirm this by benchmarking an index (STOXX index) compiled of a number of European football teams. Our results show that football clubs do in fact follow the clear pattern of other entities and sectors and previous research with regard to underperformance in the long run. We find that football clubs’ stocks are less volatile than the general market and have a low beta. With regards to over/underpricing, we only obtain data for a few football clubs. We find small signs of underpricing but are not able to confirm that this is statistical significant due to the size of our sample.

Regional assessment of the effects of land use on water quality: A case study in the Oldman River Basin, Alberta

Howery, Jocelyn 11 1900 (has links)
Protecting and managing Canadian water resources in the face of growing cumulative effects and non-point source pollution from development (industrial, agricultural, and urban), depends on defensible, scientifically founded, watershed assessments. The objectives of this research were to broadly characterize the spatial and temporal patterns in water quality (total phosphorus and total nitrogen concentration, export and yield) across a land use disturbance gradient (forest, agriculture, urban) to elucidate pressures on water quality from specific landscape regions within the three headwater sub-basins of the Oldman River basin. While the water quality in the Oldman basin, remains fairly pristine, important spatial differences in nutrient production were evident between the upstream (predominantly forested) and the downstream (mixed agricultural/forested) reaches within the sub-basins. Using the pressure state response model as a framework to link landscapes to observed water quality, it was also found that phosphorus contamination may be an issue in the headwaters. / Water and Land Resources

Institutional requirements for watershed cumulative effects assessment in the south Saskatchewan watershed

Sheelanere, Poornima 29 June 2010
Watersheds in Canada are under increasing threats due to the cumulative environmental effects from natural and anthropogenic sources. Cumulative effect assessment (CEA), however, if done at all is typically done on a project-by-project basis. This project-based approach to CEA is not sufficient to address the cumulative effects of multiple stressors in a watershed or a region. As a result, there is now a general consensus that CEA must extend from the project to the more regional scale. The problem, however, is that while the science of how to do watershed CEA (W-CEA) is progressing, the appropriate institutional arrangements to sustain W-CEA have not been addressed. Based on a case study of the South Saskatchewan Watershed (SSW), this research is aimed to identify the institutional requirements necessary to support and sustain W-CEA.<p> The research methods include document reviews and semi-structured interviews with regulators, administrators, watershed coordinators, practitioners, and academics knowledgeable on cumulative effect assessment and project-based environmental assessments (EAs). The findings from this research are presented thematically. First, participants perspectives on cumulative effects, the current state of CEA practice, and general challenges to project-based approaches to CEA are presented. The concept of WCEA is then examined, with a discussion on the need for linking project-based CEA and W-CEA. This is followed by the institutional requirements for W-CEA. The Chapter concludes with foreseeable challenges to implementing W-CEA, as identified by research participants.<p> The key findings include that cumulative effect assessments under project-based EAs are rarely undertaken in the SSW, and the project-based EA approach is faced with considerable challenges. The project-based EA challenges suggested by interview participants are similar to the ones discussed in the literature, and are primarily related to the lack of guidance to proponents regarding boundaries of assessments and thresholds, the lack of data from other project EAs, and the lack of capacity of both proponents and regulators to achieve a good CEA under project EA. These challenges could be addressed by establishing regional objectives at a broader scale, which could provide better context to project-based approaches. Further, interview results revealed several opportunities for the government to take the lead in implementing and sustaining W-CEA, but a multistakeholder approach is essential to W-CEA success. The results also suggest that the establishments of thresholds and data management are necessary components of W-CEA, but that the need for legislation concerning such thresholds and W-CEA initiatives is not agreed upon. At the same time, research results emphasize that the coordination and education among various stakeholders will be difficult to achieve. The lack of financial commitment, political will, and difficulties in establishing cause-effect relationships currently impede the implementation of W-CEA.
