Irreconcilable Differences? The Troubled Marriage Of Science And Law, Susan Haack Jan 2009

Irreconcilable Differences? The Troubled Marriage Of Science And Law, Susan Haack

Law and Contemporary Problems

There haven't always been scientific witnesses: in fact, there haven't always been witnesses. In early medieval times, courts relied on tests by oath, ordeal, and sometimes by combat. Here, Haack provides a brief historical background to the use of scientific experts in law and then proceeds to discuss in greater detail the values underlying scientific inquiry, the uncertainty in the quest of knowledge and understanding, and the methods by which consensus is reached, even if that consensus is always tentative. She then contrasts scientific inquiry with the law's quest for "truth" in the courtroom and, particularly, the normative and temporal …


Merton And The Hot Tub: Scientific Conventions And Expert Evidence In Australian Civil Procedure, Gary Edmond Jan 2009

Merton And The Hot Tub: Scientific Conventions And Expert Evidence In Australian Civil Procedure, Gary Edmond

Law and Contemporary Problems

Recently in Australia, common-law judges began to modify the way expert evidence is prepared and presented. Judges from a range of civil jurisdictions have conscientiously sought to reduce expert partisanship and the extent of expert disagreement in an attempt to enhance procedural efficiency and improve access to justice. One of these reforms, concurrent evidence, enables expert witnesses to participate in a joint session with considerable testimonial latitude. This represents a shift away from an adversarial approach and a conscientious attempt to foster scientific values and norms. Here, Edmond describes how changes to Australian civil procedure, motivated by judicial concerns about …


A Man’S Right To Choose His Surname In Marriage: A Proposal, Michael Mahoney Frandina Jan 2009

A Man’S Right To Choose His Surname In Marriage: A Proposal, Michael Mahoney Frandina

Duke Journal of Gender Law & Policy

[...] a brief history of marital and naming practices will outline how these two concepts have shifted to a primarily private issue today, as compared with the Middle Ages, when they were primarily public issues highly concerned with property matters. [...] naming involves important issues in the construction of one's identity.

The biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data. Tests using modern pollen data from 381 samples derived from 287 locations broadly reproduce potential natural vegetation. The strong temperature gradient associated with the Andes is recorded by a transition from high altitude cool grass/shrubland and cool mixed forest to mid-altitude cool temperate rain forest, to tropical dry, seasonal and rain forest at low altitudes. Reconstructed biomes from a number of sites do not match the potential vegetation due to local factors such as human …

A Remote Sensing And Gis-Assisted Spatial Decision Support System For Hazardous Waste Site Monitoring, John R. Jensen, Michael E. Hodgson, Maria Garcia-Quijano, Jungho Im, Jason A. Tullis Jan 2009

A Remote Sensing And Gis-Assisted Spatial Decision Support System For Hazardous Waste Site Monitoring, John R. Jensen, Michael E. Hodgson, Maria Garcia-Quijano, Jungho Im, Jason A. Tullis

Faculty Publications

Humans produce large amounts of waste that must be processed or stored so that it does not contaminate the environment. When hazardous wastes are stored, waste site monitoring is typically conducted in situ which can lead to a serious time lag between the onset of a problem and detection. A Remote Sensing and GIS-assisted Spatial Decision Support System for Hazardous Waste Site Monitoring was developed to improve hazardous waste site management. The system was designed to be recursive, flexible, and integrative. It is recursive because the system is implemented iteratively until the risk assessment subsystem determines that an event is …

The Arctic In World Environmental History, Jonathan D. Greenberg Jan 2009

The Arctic In World Environmental History, Jonathan D. Greenberg

Vanderbilt Journal of Transnational Law

For millions of years, the Arctic has been the world's most important "barometer of global change and amplifier of global warming." For twenty thousand years, the Arctic has been the homeland of modern human settlement, and it has played a central role in the interplay between global climate change and human migration throughout Eurasia and the Americas. Since the late fifteenth century, Arctic aboriginal peoples, lands, and seas have been thoroughly integrated into the international history of European trade, capitalism, and colonization; the territorial expansion of modern nation states; and the transnational strategic history since the outset of the Cold …


After Iraq: The Search For A Sustainable National Security Strategy, Colin S. Gray Dr. Jan 2009

After Iraq: The Search For A Sustainable National Security Strategy, Colin S. Gray Dr.

Books, Monographs & Collaborative Studies

A sustainable national security strategy is feasible only when directed by a sustainable national security policy. In the absence of policy guidance, strategy will be meaningless. The only policy that meets both the mandates of American culture and the challenges of the outside world is one that seeks to lead the necessary mission of guarding and advancing world order. The author considers and rejects a policy that would encourage the emergence of a multipolar structure to global politics. He argues that multipolarity not only would fail to maintain order, it would also promote conflict among the inevitably rival great powers. …


Ancient Leishmaniasis In A Highland Desert Of Northern Chile, Maria Antonietta Costa, Carney Matheson, Lucia Iachetta, Otto Appenzeller Jan 2009

Ancient Leishmaniasis In A Highland Desert Of Northern Chile, Maria Antonietta Costa, Carney Matheson, Lucia Iachetta, Otto Appenzeller

Harold W. Manter Laboratory of Parasitology: Library Materials

Background

Leishmaniasis is an infectious disease endemic today in many areas of South America.

Methodology

We discovered morphologic and molecular evidence of ancient infections in four female skulls in the archaeological cemetery of Coyo Oriente, in the desert of San Pedro de Atacama, northern Chile. The boney facial lesions visible in the skulls could have been caused by a number of chronic infections including chronic Leishmaniasis. This diagnosis was confirmed using PCR-sequenced analyses of bone fragments from the skulls of the affected individuals. Leishmaniasis is not normally found in the high-altitude desert of northern Chile; where the harsh climate does …


The Coordination Pyramid: A Perspective On The State Of The Art In Coordination Technology, Anita Sarma, David Redmiles, André Van Der Hoek Jan 2009

The Coordination Pyramid: A Perspective On The State Of The Art In Coordination Technology, Anita Sarma, David Redmiles, André Van Der Hoek

School of Computing: Technical Reports

Effective coordination is essential for any group work and has been studied widely in the fields of Management Science and Organizational Behavior. A classic definition of coordination is “the management of task dependencies” as proposed by Thompson [16], who distinguished among pooled tasks, where the results of individual actions are simply aggregated; sequential tasks, where the output for one is the input for another; and reciprocal tasks, where work flows back and forth between tasks. More recently, Malone and Crowston [12] developed detailed catalogs of general types of interdependencies that occur across many domains, and particular types of dependencies that …

Department of Earth and Atmospheric Sciences: Faculty Publications

The premise of this article is that climate effects on lakes can be quantified most effectively by the integration of process-oriented limnological studies with paleolimnological research, particularly when both disciplines operate within a common conceptual framework. To this end, the energy (E)–mass (m) flux framework (Em flux) is developed and applied to selected retrospective studies to demonstrate that climate variability regulates lake structure and function over diverse temporal and spatial scales through four main pathways: rapid direct transfer of E to the lake surface by irradiance, heat, and wind; slow indirect effects of E via changes in …


Holocene Carbon Burial By Lakes In Sw Greenland, N. J. Anderson, W. D'Andrea, Sherilyn C. Fritz Jan 2009

Holocene Carbon Burial By Lakes In Sw Greenland, N. J. Anderson, W. D'Andrea, Sherilyn C. Fritz

Department of Earth and Atmospheric Sciences: Faculty Publications

The role of the Arctic in future global change processes is predicted to be important because of the large carbon (C) stocks contained in frozen soils and peatlands. Lakes are an important component of arctic landscapes although their role in storing C is not well prescribed. The area around Kangerlussuaq, SW Greenland (66–68°N, 49–54°W) has ex¬tremely high lake density, with ~20 000 lakes that cover about 14% of the land area. C accumulation rates and standing stock (kg C m−2), representing late- to mid-Holocene C burial, were calculated from AMS 14C-dated sediment cores from 11 lakes. Lake …


Estimating Hydraulic Conductivity From Drainage Patterns Derived From Dem -- A Case Study In The Oregon Cascades, B. P. Grudzinski, W. Luo, Daryll Pederson Jan 2009

Estimating Hydraulic Conductivity From Drainage Patterns Derived From Dem -- A Case Study In The Oregon Cascades, B. P. Grudzinski, W. Luo, Daryll Pederson

Department of Earth and Atmospheric Sciences: Faculty Publications

Hydraulic conductivity is an important parameter in hydrology which describes the ease with which water moves through porous media. This parameter is also important in understanding the hydrology of Mars. On Earth, this parameter can be measured by conducting controlled experiments in laboratories or conducting pumping tests in the field. This study introduces a new method of estimating hydraulic conductivity from drainage dissection pattern derived from digital elevation model (DEM). This method can be applied to Mars if it is robustly tested on Earth.


A New Record Of Procynosuchus Delaharpeae (Therapsida: Cynodontia) From The Upper Permian Usili Formation, Tanzania, D. Marie Weide, Christian A. Sidor, Kenneth D. Angielczyk, Roger M. H. Smith Jan 2009

A New Record Of Procynosuchus Delaharpeae (Therapsida: Cynodontia) From The Upper Permian Usili Formation, Tanzania, D. Marie Weide, Christian A. Sidor, Kenneth D. Angielczyk, Roger M. H. Smith

Department of Earth and Atmospheric Sciences: Faculty Publications

Procynosuchus, the best-known Permian cynodont, has a remarkably broad geographic range, with records stretching from southern Africa to Europe. Fossils' of Procynosuchus are most common in the Upper Permian Dicynodon Assemblage Zone of South Africa, but also occur in coeval East African rocks. Currently, there is one documented occurrence from the Madumabisa Mudstone Formation of Zambia, and two specimens from the Usili (=Kawinga) Formation of Tanzania. The Tanzanian specimens include a poorly preserved, incomplete skull and a partial cranium originally attributed to Parathrinaxodon proops. The latter is now considered a subjective junior synonym of Procynosuchus delaharpeae. Here we …


"Israel": An Abstract Concept Or Concrete Reality In Recent Judeo-Argentinean Narrative?, Amalia Ran Jan 2009

"Israel": An Abstract Concept Or Concrete Reality In Recent Judeo-Argentinean Narrative?, Amalia Ran

Spanish Language and Literature Papers

The re-democratization process in Argentina, beginning at the end of 1983, emphasized a tendency that had emerged within the Judeo-Argentinean fiction (and Argentinean narrative in general) to contemplate on the collective and personal memory, while creating a type of dialogue with the general historic context of the twentieth century. This process was un-masqueraded as a political and literary strategy in order to re-create an "archive" and re-construct it in a way that would correspond to the new material circumstances of the Argentinean nation and its society at that specific moment. The dilemma of how to define the essence of Jewish …


Problems With The Claim Of Ecotype And Taxon Status Of The Wolf In The Great Lakes Region, Matthew A. Cronin, L. David Mech Jan 2009

Problems With The Claim Of Ecotype And Taxon Status Of The Wolf In The Great Lakes Region, Matthew A. Cronin, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Koblmuller et al. (2009) analyzed molecular genetic data of the wolf in the Great Lakes (GL) region of the USA and concluded that the animal was a unique ecotype of grey wolf and that genetic data supported the population as a discrete wolf taxon. However, some of the literature that the researchers used to support their position actually did not, and additional confusion arises from indefinite use of terminology. Herein, we discuss the problems with designation of a wolf population as a taxon or ecotype without proper definition and assessment of criteria.

Koblmuller et al. (2009) wrote ‘The GL …


Agroecology As A Science, A Movement And A Practice: A Review, A. Wezel, S. Bellon, T. Doré, Charles A. Francis, D. Vallod, C. David Jan 2009

Agroecology As A Science, A Movement And A Practice: A Review, A. Wezel, S. Bellon, T. Doré, Charles A. Francis, D. Vallod, C. David

Department of Agronomy and Horticulture: Faculty Publications

Agroecology involves various approaches to solve actual challenges of agricultural production. Though agroecology initially dealt primarily with crop production and protection aspects, in recent decades new dimensions such as environmental, social, economic, ethical and development issues are becoming relevant. Today, the term ‘agroecology’ means either a scientific discipline, agricultural practice, or political or social movement. Here we study the different meanings of agroecology. For that we analyse the historical development of agroecology. We present examples from USA, Brazil, Germany, and France. We study and discuss the evolution of different meanings agroecology. The use of the term agroecology can be traced …


Prpl: An Open-Source General-Purpose Parallel Raster Processing Programming Library, Qingfeng Guan Jan 2009

Prpl: An Open-Source General-Purpose Parallel Raster Processing Programming Library, Qingfeng Guan

Geography Program: Faculty Publications

pRPL is an open-source general-purpose programming library developed by the author to parallelize almost any raster-processing algorithm with any arbitrary neighborhood configuration, and support any data type. This paper introduces the advanced features of pRPL, compares it with other similar programming libraries, and demonstrates the performance of a parallel geographic Cellular Automata (CA) model developed using pRPL with real-world datasets. In conclusion, pRPL effectively reduces the development complexity of parallel programming, and efficiently reduces the computing time.


Recent Occurrence Of An American Black Bear In Nebraska, Justin D. Hoffman, Sam Wilson, Hugh H. Genoways Jan 2009

Recent Occurrence Of An American Black Bear In Nebraska, Justin D. Hoffman, Sam Wilson, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

We report on a young male, cinnamon-phase American black bear (Ursus americanus) that was collected in northwestern Nebraska on May 12, 2008. This specimen represents the first black bear taken in Nebraska since 1907. Cranial characteristics and mass of the individual indicated a 15–16-month old bear. This bear may have dispersed from the Laramie Mountains in southeastern Wyoming along the North Platte River into western Nebraska. This record adds to the growing number of cases where large carnivores are reinvading previously occupied territory in the Great Plains. These reinvasions potentially have broad ecological implications to local prey populations …


Forecasting The Combined Effects Of Urbanization And Climate Change On Stream Ecosystems: From Impacts To Management Options, Kären C. Nelson, Margaret A. Palmer, James E. Pizzuto, Glenn A. Moglen, Paul L. Angermeier, Robert H. Hilderbrand, Michael Dettinger, Katharine Hayhoe Jan 2009

Forecasting The Combined Effects Of Urbanization And Climate Change On Stream Ecosystems: From Impacts To Management Options, Kären C. Nelson, Margaret A. Palmer, James E. Pizzuto, Glenn A. Moglen, Paul L. Angermeier, Robert H. Hilderbrand, Michael Dettinger, Katharine Hayhoe

United States Geological Survey: Staff Publications

Streams collect runoff, heat, and sediment from their watersheds, making them highly vulnerable to anthropogenic disturbances such as urbanization and climate change. Forecasting the effects of these disturbances using process-based models is critical to identifying the form and magnitude of likely impacts. Here, we integrate a new biotic model with four previously developed physical models (downscaled climate projections, stream hydrology, geomorphology, and water temperature) to predict how stream fish growth and reproduction will most probably respond to shifts in climate and urbanization over the next several decades.


Prevalence Of West Nile Virus In Migratory Birds During Spring And Fall Migration, Robert J. Dusek, Robert G. Mclean, Laura D. Kramer, Sonya R. Ubico, Alan P. Dupuis Ii, Gregory D. Ebel, Stephen C. Guptill Jan 2009

Prevalence Of West Nile Virus In Migratory Birds During Spring And Fall Migration, Robert J. Dusek, Robert G. Mclean, Laura D. Kramer, Sonya R. Ubico, Alan P. Dupuis Ii, Gregory D. Ebel, Stephen C. Guptill

United States Geological Survey: Staff Publications

To investigate the role of migratory birds in the dissemination of West Nile virus (WNV), we measured the prevalence of infectious WNV and specific WNV neutralizing antibodies in birds, principally Passeriformes, during spring and fall migrations in the Atlantic and Mississippi flyways from 2001–2003. Blood samples were obtained from 13,403 birds, representing 133 species. Specific WNV neutralizing antibody was detected in 254 resident and migratory birds, representing 39 species, and was most commonly detected in northern cardinals (Cardinalis cardinalis ) (9.8%, N = 762) and gray catbirds ( Dumetella carolinensis ) (3.2%, N = 3188). West Nile virus viremias …


Updating The 2001 National Land Cover Database Land Cover Classification To 2006 By Using Landsat Imagery Change Detection Methods, George Xian, Collin Homer, Joyce Fry Jan 2009

Updating The 2001 National Land Cover Database Land Cover Classification To 2006 By Using Landsat Imagery Change Detection Methods, George Xian, Collin Homer, Joyce Fry

United States Geological Survey: Staff Publications

The recent release of the U.S. Geological Survey (USGS) National Land Cover Database (NLCD) 2001, which represents the nation's land cover status based on a nominal date of 2001, is widely used as a baseline for national land cover conditions. To enable the updating of this land cover information in a consistent and continuous manner, a prototype method was developed to update land cover by an individual Landsat path and row. This method updates NLCD 2001 to a nominal date of 2006 by using both Landsat imagery and data from NLCD 2001 as the baseline. Pairs of Landsat scenes in …


A Robust, Multisite Holocene History Of Drift Ice Off Northern Iceland: Implications For North Atlantic Climate, John T. Andrews, Dennis Darby, Dennis Eberle, Anne E. Jennings, Matthias Moros, Astrid Ogilvie Jan 2009

A Robust, Multisite Holocene History Of Drift Ice Off Northern Iceland: Implications For North Atlantic Climate, John T. Andrews, Dennis Darby, Dennis Eberle, Anne E. Jennings, Matthias Moros, Astrid Ogilvie

United States Geological Survey: Staff Publications

An important indicator of Holocene climate change is provided by evidence for variations in the extent of drift ice. A proxy for drift ice in Iceland waters is provided by the presence of quartz. Quantitative xray diffraction analysis of the < 2 mm sediment fraction was undertaken on 16 cores from around Iceland. The quartz weight (wt.)% estimates from each core were integrated into 250-yr intervals between −0.05 and 11.7 cal. ka BP. Median quartz wt.% varied between 0.2 and 3.4 and maximum values ranged between 2.8 and 11.8 wt.%. High values were attained in the early Holocene and minimum values were reached 6–7 cal. ka BP. Quartz wt.% then rose steadily during the late Holocene. Our data exhibit no correlation with counts on haematite-stained quartz (HSQ) grains from VM129-191 west of Ireland casting doubt on the ice-transport origin. A pilot study on the provenance of Fe oxide grains in two cores that cover the last 1.3 and 6.1 cal. ka BP indicated a large fraction of the grains between 1 and 6 cal. ka BP were from either Icelandic or presently unsampled sources. However, there was a dramatic increase in Canadian and Russian sources from the Arctic Ocean ~1 cal. ka BP. These data may indicate the beginning of an Arctic Oscillation-like climate mode.


Nagmia Rodmani N. Sp., Nagmia Cisloi N. Sp. And Probolitrema Richiardii (López, 1888) (Gorgoderidae: Anaporrhutinae) From Elasmobranchs In The Gulf Of California, Mexico, Stephen S. Curran, Charles K. Blend, Robin M. Overstreet Jan 2009

Nagmia Rodmani N. Sp., Nagmia Cisloi N. Sp. And Probolitrema Richiardii (López, 1888) (Gorgoderidae: Anaporrhutinae) From Elasmobranchs In The Gulf Of California, Mexico, Stephen S. Curran, Charles K. Blend, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The generic diagnosis of Nagmia Nagaty, 1930, is emended to include species having some vitelline follicles extending into the extracecal space. Two new species belonging in the genus are described from the Gulf of California: Nagmia rodmani n. sp. from the body cavity of the giant electric ray, Narcine entemedor Jordan and Starks, 1895, and Nagmia cisloi n. sp. from the body cavity of the smoothtail mobula, Mobula thurstoni (Lloyd, 1908). Both species are distinguished from each other and the 13 other known congeners by the number of testicular follicles, ratio of widths of oral sucker to ventral sucker, and …


Climate Trends Of The North American Prairie Pothole Region 1906–2000, Bruce Millett, W. Carter Johnson, Glenn Guntenspergen Jan 2009

Climate Trends Of The North American Prairie Pothole Region 1906–2000, Bruce Millett, W. Carter Johnson, Glenn Guntenspergen

United States Geological Survey: Staff Publications

The Prairie Pothole Region (PPR) is unique to North America. Its millions of wetlands and abundant ecosystem goods and services are highly sensitive to wide variations of temperature and precipitation in time and space characteristic of a strongly continental climate. Precipitation and temperature gradients across the PPR are orthogonal to each other. Precipitation nearly triples from west to east from approximately 300 mm/year to 900 mm/year, while mean annual temperature ranges from approximately 1°C in the north to nearly 10°C in the south. Twentieth-century weather records for 18 PPR weather stations representing 6 ecoregions revealed several trends. The climate generally …

Commanding The Green Centre Line In Normandy: A Case Study Of Division Command In The Second World War, Angelo N. Caravaggio Jan 2009

Commanding The Green Centre Line In Normandy: A Case Study Of Division Command In The Second World War, Angelo N. Caravaggio

Theses and Dissertations (Comprehensive)

This thesis examines the experiences of the 4th Canadian Armoured Division as it prepared for and carried out its role in the battle of Normandy and the libeation of France in 1944. The factors that limmited opportunities to practice the formation in large-scale exercises are noted as are the methods used by the General Officer Commanding, Major-General George Kitching, to compensate for the limitations. This thesis argues that through the development of an effective commander-staff dynamic Kitching, his staff and his subordinates commanders, were able to meet the challenges and chaos of combat in the final stages of the Normandy …
