Visuomenės švietimas aplinkosaugos valdymo klausimais Šiaulių regione / Education of Society on Issues of Management of Environmental Protection

Augustauskienė, Joana 02 June 2006 (has links)
In the study, there is performed a research on the issues education of the society of the management of environmental protection. There are analysed the main acts of law, regulating environmental protection and public information, education on this activities, there is emphasised correlation of institutions of environmental protection. In the present study of master, there is performed analysis of the articles of the most popular day papers “Šiaulių naujienos” and “Šiaulių kraštas” on topic of environmental protection. The present study of master consists of two parts: 1) management of environmental protection in the country and Šiauliai Region; 2) Means of public education in environmental protection. During the study (2003-2005), there were found 488 articles on the topic of environmental protection. The most of articles were published about waste management, environmental condition, protection of water, flora and fauna. The least were found the articles concerning analysis of issues of effluents and environmental protection of air. The performed research has demonstrated, that the articles are normally designed to inform about accomplished events, ecological accidents and et cetera. There was almost not introduced any information how the society should participate in management of environmental protection (how to use natural resources rationally, to decrease impurity of water or air, how to manage - sort waste, emerging in daily life and production and so on).

Landscape protection and urban development setbacks : establishing policy recommendations for the city of Red Deer

Poth, Trevor James 09 August 2013 (has links)
As urban municipalities grow, local governments are tasked with balancing the economic, political, social, and environmental needs of their communities in an effort to develop sustainable urban planning policies. This thesis uses the City of Red Deer as a single case study to examine a municipality's vision of urban sustainability within the context of ecological planning and protection. Concepts of ecosystem goods and services, biodiversity protection, and enhanced water quality were reviewed with research on riparian management, landscape level planning, and ecological protection to provide a lens for reviewing Red Deer's land protection framework. Ultimately, this research provides policy recommendations for development setbacks and land preservation strategies which could greatly contribute to the long-term sustainability of the community. Although this research focuses on the City of Red Deer, the policy recommendations can be applied to similar municipalities and landscapes across the nation.

Physical response of composite geomembrane / geosynthetic clay liners under simulated landfill conditions

Dickinson, SIMON 05 September 2008 (has links)
The physical response of composite landfill liners consisting of a geomembrane on top of a geosynthetic clay liner (GCL) are examined under simulated landfill conditions. The deformation and strains of a 1.5-mm-thick high-density polyethylene geomembrane and thickness and hydraulic performance of a nominally 7-mm-thick GCL are quantified when the composite liner was buried beneath 50 mm coarse gravel, at applied pressures up to 1000 kPa, with a firm sand foundation layer, and with and without a wrinkle in the geomembrane. At an applied pressure of 250 kPa, with either no protection or conventional thick nonwoven needle-punched geotextile protection layers, the tensile strains in the geomembrane exceeded a 3% allowable limit and the GCL was reduced in thickness to as little as 2.2 mm from extrusion of bentonite beneath a gravel particle. Whereas a 150-mm-thick sand protection layer limited strains in the geomembrane to 0.1% and prevented extrusion in the GCL so that deformation was from bentonite consolidation and not from extrusion. A GCL with a thickness of less than 3 mm from extrusion was shown to be susceptible to failure from internal erosion of bentonite in the GCL at hydraulic head differences across the GCL between 1-10 m. Conversely with the sand protection layer, the GCL could withstand a head difference of greater than 100 m without any evidence of internal erosion. Further, the permittivity of an extruded 3.5-mm-thick GCL was found to be 4.5 times larger than a 7-mm-thick GCL that did not experience extrusion. / Thesis (Ph.D, Civil Engineering) -- Queen's University, 2008-09-05 10:47:21.783

Floral development and fruit set of tomato as influenced by mini-tunnels

Champagne, Linda January 1991 (has links)
Field experiments were established during the 1988 and 1989 growing seasons, to determine the effect of mini-tunnel management systems on floral development and fruit set of tomato (Lycopersicon esculentum Mill.). Two types of floral abnormalities reported to be caused by temperatures above 30$ sp circ$C were observed, namely: style exsertion and splitting of the antheridial cone. Clear vented and white non-vented mini-tunnels reduced the incidence of both these abnormalities compared to the controls in 1988. As a consequence these two types of mini-tunnels also had the greatest percentage fruit set and total marketable yield of the first three clusters. In 1989, none of the mini-tunnels tested significantly increased percentage fruit set or marketable yield. The cultivar Springset produced ripe fruits an average of 4 days before Hope#1 and 7 days before Celebrity in both 1988 and 1989.

Stewardship as partnership : a comparative study of positive human-environment relationships in East Cree and suburban Montreal communities

Forrest, Margaret Anne. January 2006 (has links)
This study suggests that cultural acknowledgement of the integral partnership between a human community and the environment it inhabits is central to the development of positive human-environment relationships. The comparison of two community environmental projects illustrates cultural implications of human land occupancy through comparisons of their governing land use institutions as well as social and individual experiences. In the Paakumshumwaau-Wemindji project environmental responsibility is strongly motivated by the interaction of shared cosmological understandings with direct experience in the landscape. The creation of Edgewater Park in suburban Pointe Claire is a clear indication of community environmental responsibility working its way towards new partnerships with lakeshore ecological communities. The fundamental difference in these partnerships inheres however in the distinct ways the two human communities understand the voice of the non-human elements within the partnership.

Making Decisions: Social work processes and the construction of risk(s) in child protection work

Stanley, Tony W. January 2005 (has links)
Through practices of assessment and consultation, information gathering and analysis, social workers, in the field of child protection, build understandings about children and families. Social workers actively construct knowledge as they engage in assessments of children referred to them as potentially 'at risk'. Their work is always informed by explicit or implicit theories about risk and protection. The active engagement with risk by social workers is the central focus for this inquiry. This thesis presents an exploratory inquiry into the work of child protection in Aotearoa/New Zealand as experienced by social workers employed at the Department of Child, Youth and Family Services (CYFS). The primary focus is on their understanding of risk and their active construction of risk discourses. I am interested in how children are identified as potentially at risk, and how risk is identified, worked with, managed and woven into the assessments of social workers as they engage in child protection work. This inquiry took, as its starting point, narratives of 70 social workers about specific child protection cases. They were asked to describe both straightforward and more complex assessments, and, as a result, provided a rich and detailed range of narratives about how risk is defined, assessed and managed by social workers. This qualitative study employed a critical incident technique as a data collection method, and applied a grounded approach to the analysis of these practice stories. The focus for the interviews was on the day-to-day work as experienced by social workers, that is, the practices of assessment in child protection. Probes were used to solicit further information when risk was discussed by the workers. This research also involved spending time in different branches of CYFS around the country and informal conversation with social workers. Field notes made during these periods of immersion in different practice settings were also analysed to provide understandings of the contexts in which social workers engage in individual and collective knowledge production about children and risk. This is the first detailed investigation of how New Zealand statutory social workers of different ethnicities engage with, and draw on, risk discourses in their assessment work. For the social workers in this study, risk discourses were actively and strategically used in the legitimation of their practice interventions. The practices of socially constructing knowledge about 'risk' are a continuing focus of this thesis, and the wider implications for social work practices of 'risk' assessment are discussed.

Civilt skydd vid upprorsbekämpning

Lindborg, Robin January 2015 (has links)
Counterinsurgency (COIN) has made a comeback during the early 21-century since the majority of western countries have been involved in peace enforcement in the middle-east. Since its comeback the concept of COIN have been wildly debated but also undergone some chances since its early days, today the majority of COIN theories claims that the local population is the key to winning a COIN campaign. If you gain their trust the insurgency will lose their support and recruiting base, this is the reason why collateral damage resulting in in civilian deaths are contra-productive, it creates more insurgents. This is the incitement to further examine how civilian deaths occur and can be avoided during COIN campaigns. This essay studies the American COIN campaign in Iraq between 2004 and 2009 and aims to investigate whether there is a trilemma-like relationship between the key goals of COIN: protecting civilians, protecting one’s own forces and neutralizing the enemy. Each different goal has been operationalized to something measurable – death statistics. The yearly death toll for coalition troops, Iraqi civilians and insurgents provide the empirical material necessary to answer the question if the main goals can be achieved at the same time or if it’s impossible. The essay is broken down into two parts, the first examines whether an actual people-centric COIN strategy saves civilian lives or if it’s all just in theory. The second part examines the relationship between the key goals. The result in this essay shows that a people-centric COIN strategy, as the one employed by General Petraeus in Iraq during operation Iraqi freedom, actually saves civilian lives. But it also establishes that the key goals can’t be achieved at the same time and that each strategy will come with a consequence.
