Intelligence Analysis And Threat Assessment: Towards A More Comprehensive Model Of Threat, Charles Vandepeer
Intelligence Analysis And Threat Assessment: Towards A More Comprehensive Model Of Threat, Charles Vandepeer
Australian Security and Intelligence Conference
A central focus of intelligence is the identification, analysis and assessment of threat. However, as acknowledged by intelligence practitioners, threat assessment lags behind the related field of risk assessment. This paper highlights how definitions of threat currently favoured by intelligence agencies are primarily based on threatening entities alone. Consequently, assessments of threat are almost singularly concerned with understanding an identified enemy’s intentions and capabilities. This ‘enemy-centric’ approach to intelligence analysis has recently come in for criticism. In particular, the shortcomings of the current approach become apparent where the focus of intelligence analysis is on threats from difficult-to-identify sub-state or non-state …

The 2011 American State Litter Scorecard:New Rankings For An Increasingly Environmentally Concerned Population, Stephen [Steve] L. Spacek
Stephen [Steve] L Spacek
By popular demand--a NEW, up-to-date State Litter "Scorecard" is now released for the 2011 ASPA Baltimore event--measuring each state’s overall environmental quality through public property/spaces debris removal efforts. The “CARD” uses tried-and-true, hard-to-publicly obtain objective and subjective measures, leading to a total overall score for each measured jurisdiction. Readers can thus gain a realistic "picture" of "what's going on" within one or all of the 50 states. Littering/dumping remains harmful, serious American environmental crimes, creating dangers to public health and safety, and contributing to the deaths of over 800 Americans in debris-attributed motor vehicle accidents. The first, original 2008 Scorecard …

The Response Of Fish Larvae To Decadal Changes In Environmental Forcing Factors Off The Oregon Coast, Toby D. Auth, Richard D. Brodeur, Heather L. Soulen, Lorenzo Ciannelli, William T. Peterson
United States Department of Commerce: Staff Publications
We conducted a statistical analysis to characterize the influence of large-scale and local environmental factors on presence-absence, concentration, and assemblage structure of larval fish within the northern California Current (NCC) ecosystem, based on samples collected at two nearshore stations along the Newport Hydrographic line off the central Oregon coast. Data from 1996 to 2005 were compared with historical data from the 1970s and 1980s to evaluate pseudo-decadal, annual, and seasonal variability. Our results indicate that the most abundant taxa from 1996 to 2005 differ from those of earlier decades. Concentrations of the dominant taxa and total larvae were generally greater …

Public Awareness About Global Warming In Hyderabad, India, Vani Sarraju Rao
Master's Theses
This study addressed public perceptions and awareness about global warming in India through a survey of 851 subjects in the city of Hyderabad in the year 2007. A stratified sample of nine segments of society showed that, although people consider global warming a serious problem, they do not clearly understand its causes, impacts, and solutions. The data analyses using paired T-tests indicated differences in levels of awareness about global warming, across age and education. ANOVA and regression analysis suggested that levels of awareness among respondents varied according to their occupation. The degree of seriousness with which subjects viewed global warming …

Novel Lc-Ms Methods For The Determination Of Environmental And Food Contaminants Incorporating Analyte Confirmation Using High Resolution Ms, Michael George Cahill
Theses
The contamination of the aquatic environment with pesticides has become an emerging environmental issue because of the potential risk to human health and wildlife. Effluent from wastewater treatment plants (WWTPs) have been identified as an important source of microorganic contaminants in the environment. The EC have implemented several directives for the control of pesticides in the environment including the 98/83/EEC directive establishing the concentration of pesticide allowed for human consumption, the 2000/60/EC directive set up to monitor priority pollutants that are hazardous substances in the environment and REACH ensuring these substances are registered, controlled, therefore ensuring that the industry is …

A Risk Assessment Based Model For Assessing The Environmental Sustainability Of Tourism And Recreation Areas, Peter Roe
Doctoral
Assessing the environmental quality of tourism and recreation areas is considered fundamental to the sustainable management of these resources. However, existing methodologies for such assessments rely on sets of environmental data that are often poorly linked and difficult to interpret and integrate in a holistic manner. Risk assessment is a concept that has developed to the point where it has the potential to address current limitations in environmental assessment methodologies. This thesis presents a new model for the application of risk assessment to the management and assessment of environmental sustainability in the tourism and recreation sector. This model was applied …

There is an ever-increasing need for biomarkers to identify toxic stress in the aquatic environment. Such techniques need to be accurate, expeditious, ethical and economical. Typically, in vitro based platforms fit these criteria however many of these systems often undergo ‘assay drift’ and consequently do not fully represent the real-life situation.
In recent years, there has been growing interest in the mitochondrion and its (dys)function …

Nitrogen doped anatase-rutile heterojunctions are successfully synthesized through an ethylene-diaminetetraacetic acid (EDTA) modified sol-gel process.An FT-IR study of EDTA modified TiO2 gel confirms the existence of an ionic intermediate (as indicated by a Δν value of 233 cm-1).Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Raman spectroscopy are employed to study the phase evolution, phase purity, and crystallite size of samples. Formations of O-Ti-N and N-Ti-N bonds in calcined samples are confirmed using XPS and FT-IR spectro- scopy. AllEDTAmodified samples show significantly higher visible light photocatalytic activity than the unmodified sample. The most active nitrogen doped heterojunction obtained at 400C …
Planning For Closure Of The Logan City/Cache County Landfill And Surrounding Landscape, Kristofor Lee Kvarfordt
Planning For Closure Of The Logan City/Cache County Landfill And Surrounding Landscape, Kristofor Lee Kvarfordt
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Planning for closure requires in depth analysis into many operational, environmental, and social factors. Ideally, the planning process should resolve as many of the technical, social, and aesthetic requirements as possible by systematically addressing the various elements that influence the final design. This research identified the significant issues related to planning for the end use of the current Logan landfill after it reaches capacity in 18-20 years and the associated lagoons and wetlands. The current closure plan calls for simply recontouring the landfill to stabilize the slopes, then revegetating. The location of the site has serious implications for environmental impact …

Not Empty, Lauren Orme
Scripps Senior Theses
Not Empty is a two- part exploration of the relationship between humans and nature. In this essay I intend to discuss the relationship Australian Aboriginal peoples have with their environment. Their many cultures are among the oldest surviving civilizations on the planet, and their natural history is rich and complex. I plan to compare the relationship Australian Aboriginal cultures have to their environment to that of a Western civilization, specifically the United States. Neither relationship is perfect, nor is one of them 'better.' Both have histories riddled with extinction, evolution, and the conquest of new lands. The struggle Aboriginal Australians …

Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne., Taylor Sloey
Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne., Taylor Sloey
Department of Environmental Studies: Undergraduate Student Theses
Abstract
The purpose of this research was to study the sex distribution and energy allocation of dioecious Eastern Red Cedars (Juniperus virginiana) along an environmental resource gradient. The trees surveyed were growing in a canyon located at the University of Nebraska’s Cedar Point Biological Research Station in Ogallala, Nebraska. Due to the geography of this canyon, environmental factors necessary for plant growth should vary depending on the tree’s location within the canyon. These factors include water availability, sun exposure, ground slope, and soil nitrogen content, all of which are necessary for carbon acquisition.
Juniperus virginiana is a dioecious conifer. Dioecious …
The Impact Of Individual Decision Making On Campus Sustainability Initiatives, Aurali Ella Dade
The Impact Of Individual Decision Making On Campus Sustainability Initiatives, Aurali Ella Dade
UNLV Theses, Dissertations, Professional Papers, and Capstones
Institutions of Higher Education (IHEs) have increasingly committed to become more sustainable in recent years. Despite this commitment, academic publications in the sustainability field assert that progress has been slower at IHEs than expected and that most IHEs have found sustainability initiatives difficult to implement. Comprehensive sustainability initiatives require cooperation from a broad set of constituents with diverse and sometimes conflicting goals. Creating a sustainable IHE also requires changes in both physical infrastructure and individual behavior. Any number of institutional factors can advance or limit progress towards these objectives.
Previous investigations have assessed individual case studies, compared IHEs in a …

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza
UNLV Theses, Dissertations, Professional Papers, and Capstones
While there is plenty of anecdotal evidence within the systems dynamics community supporting the use of systems simulations in the classroom to improve student understanding, there is little published, controlled, experimental research. This paper describes the results of a paired experiment testing the effect of using system dynamics simulations to increase systems understanding in an introductory environmental science course. We believed that the students using the systems simulations would demonstrate a greater systemic understanding of environmental issues than those who did not.
We conducted an experiment during the fall semester of 2009, with 304 students enrolled in four sections of …

Effects Of Socioeconomic Status On Brain Development, And How Cognitive Neuroscience May Contribute To Levelling The Playing Field, Rajeev Raizada, Mark M. Kishiyama
Dartmouth Scholarship
The study of socioeconomic status (SES) and the brain finds itself in a circumstance unusual for Cognitive Neuroscience: large numbers of questions with both practical and scientific importance exist, but they are currently under-researched and ripe for investigation. This review aims to highlight these questions, to outline their potential significance, and to suggest routes by which they might be approached. Although remarkably few neural studies have been carried out so far, there exists a large literature of previous behavioural work. This behavioural research provides an invaluable guide for future neuroimaging work, but also poses an important challenge for it: how …
