From Contract To Legislation: The Logic Of Modern International Lawmaking, Timothy Meyer Jan 2014

From Contract To Legislation: The Logic Of Modern International Lawmaking, Timothy Meyer

Faculty Scholarship

The future of international lawmaking is in peril. Both trade and climate negotiations have failed to produce a multilateral agreement since the mid-1990s, while the U.N. Security Council has been unable to comprehensively respond to the humanitarian crisis in Syria. In response to multilateralism's retreat, many prominent commentators have called for international institutions to be given the power to bind holdout states-often rising or reluctant powers such as China and the United States-without their consent. In short, these proposals envision international law traveling the road taken by federal systems such as the United States and the European Union: from contractual …

Triadic Legal Pluralism In North Sinai: A Case Study Of State, Shari'a, And 'Urf Courts In Conflict And Cooperation, Mara R. Revkin Jan 2014

Triadic Legal Pluralism In North Sinai: A Case Study Of State, Shari'a, And 'Urf Courts In Conflict And Cooperation, Mara R. Revkin

Faculty Scholarship

To the extent that legal scholars have addressed the post-authoritarian transitions underway in the Middle East, the scope of their work has been primarily confined to the formal infra-structure of state-manufactured law. Attention has focused on the activities of high courts, parliaments, and the administrative apparatus of official justice systems, while largely neglecting to acknowledge the importance of non-state institutions and systems of normative rules that operate in the shadow of modern bureaucratic governments. The concept of legal pluralism, defined as the coexistence of multiple legal or normative orders within a common geographical area, has been applied extensively in European, …

An Exploration Of “Non-Economic” Damages In Civil Jury Awards, Herbert M. Kritzer, Guangya Liu, Neil Vidmar Jan 2014

An Exploration Of “Non-Economic” Damages In Civil Jury Awards, Herbert M. Kritzer, Guangya Liu, Neil Vidmar

Faculty Scholarship

Using three primary data sources plus three supplemental sources discussed in an appendix, this paper examines how well non-economic damages could be predicted by economic damages and at how the ratio of non-economic damages to economic damages changed as the magnitude of the economic damages awarded by juries increased. We found a mixture of consistent and inconsistent patterns across our various datasets. One fairly consistent pattern was the tendency for the ratio of non-economic to economic damages to decline as the amount of economic damages increased. Moreover, the variability of the ratio also tended to decline as the amount of …

Corridos, Drugs, And Violence: An Analysis Of Mexican Drug Ballads, Kristen L. Richmond Jan 2014

Corridos, Drugs, And Violence: An Analysis Of Mexican Drug Ballads, Kristen L. Richmond

Graduate Theses, Dissertations, and Problem Reports (ETD)

Narcocorridos, or Mexican drug ballads, are a contemporary form of the corrido connected to banda music in the northern part of Mexico and along the border in the United States. The narcocorrido is sometimes compared to gangsta rap due to its exciting narratives of drug traffickers who rose above poor socio-economic conditions to become powerful and wealthy figures in the drug trade. The stories reflected in Mexican drug ballads highlight the lifestyle of drug lords and aspects of the drug trade that are imbued with violence. Narcocorrido lyrics focus on misfortunes and death while referencing events related to illegal criminal …

Effects Of The Popcorn Flavorings, Diacetyl And 2,3-Pentanedione, In The Airways, Eric J. Zaccone Jan 2014

Effects Of The Popcorn Flavorings, Diacetyl And 2,3-Pentanedione, In The Airways, Eric J. Zaccone

Graduate Theses, Dissertations, and Problem Reports (ETD)

"Popcorn workers' lung" (PWL) is a bronchiolitis obliterans-like obstructive disease caused by inhalation of butter flavoring vapor during the manufacture of microwave popcorn. Lung function tests of employees at several microwave popcorn plants revealed that the severity of abnormal lung function correlated with increasing cumulative exposure to the butter flavorant, diacetyl. Recently, the diacetyl substitute, 2,3-pentanedione, has also been identified as a respiratory hazard. The National Institute for Occupational Safety and Health (NIOSH) demonstrated in rats that inhalation of occupationally-relevant concentrations of diacetyl and 2,3-pentanedione vapor for 6 h resulted in airway epithelial necrosis and apoptosis in the nasal passages …

Cadmium Contamination Of Agricultural Soils And Crops Resulting From Sphalerite Weathering., T. C. Robson, C. B. Braungardt, J. Rieuwerts, P. Worsfold Jan 2014

Cadmium Contamination Of Agricultural Soils And Crops Resulting From Sphalerite Weathering., T. C. Robson, C. B. Braungardt, J. Rieuwerts, P. Worsfold

School of Geography, Earth and Environmental Sciences

The biogeochemistry and bioavailability of cadmium, released during sphalerite weathering in soils, were investigated under contrasting agricultural scenarios to assess health risks associated with sphalerite dust transport to productive soils from mining. Laboratory experiments (365 d) on temperate and sub-tropical soils amended with sphalerite (<63 μm, 0.92 wt.% Cd) showed continuous, slow dissolution (0.6-1.2% y(-1)). Wheat grown in spiked temperate soil accumulated ≈38% (29 μmol kg(-1)) of the liberated Cd, exceeding food safety limits. In contrast, rice grown in flooded sub-tropical soil accumulated far less Cd (0.60 μmol kg(-1)) due to neutral soil pH and Cd bioavailability was possibly also controlled by secondary sulfide formation. The results demonstrate long-term release of Cd to soil porewaters during sphalerite weathering. Under oxic conditions, Cd may be sufficiently bioavailable to contaminate crops destined for human consumption; however flooded rice production limits the impact of sphalerite contamination.

Galleria Mellonella Infection Model Demonstrates High Lethality Of St69 And St127 Uropathogenic E. Coli., Majed F. Alghoribi, Tarek M. Gibreel, Andrew R. Dodgson, Scott A. Beatson, Mathew Upton Jan 2014

Galleria Mellonella Infection Model Demonstrates High Lethality Of St69 And St127 Uropathogenic E. Coli., Majed F. Alghoribi, Tarek M. Gibreel, Andrew R. Dodgson, Scott A. Beatson, Mathew Upton

School of Biomedical Sciences

Galleria mellonella larvae are an alternative in vivo model for investigating bacterial pathogenicity. Here, we examined the pathogenicity of 71 isolates from five leading uropathogenic E. coli (UPEC) lineages using G. mellonella larvae. Larvae were challenged with a range of inoculum doses to determine the 50% lethal dose (LD50) and for analysis of survival outcome using Kaplan-Meier plots. Virulence was correlated with carriage of a panel of 29 virulence factors (VF). Larvae inoculated with ST69 and ST127 isolates (10(4) colony-forming units/larvae) showed significantly higher mortality rates than those infected with ST73, ST95 and ST131 isolates, killing 50% of the larvae …

Community Resilience, Transitional Corridors And Macro‐Scalar Lock‐In Effects, Ga Wilson Jan 2014

Community Resilience, Transitional Corridors And Macro‐Scalar Lock‐In Effects, Ga Wilson

School of Geography, Earth and Environmental Sciences

This article analyses interlinkages between community resilience, transitional corridors and macro-scalar lock-in effects, with specific emphasis on exogenous drivers. Transition theory is used as an approach to analyse resilience pathways. The article suggests that transitional corridors shape decision-making opportunities, which are ultimately mediated by the individual/household within a community and turned into action with tangible effects on resilience/vulnerability ‘on the ground’. The importance of macro-structural ‘lock-ins’ for understanding constraints and opportunities for raising community resilience is highlighted, including in particular political and policy-based decision-making pathways, macro-structural lock-ins, ideological lock-in effects and macro-economic lock-ins. The article concludes by arguing that transitional …

Functional Diversity Of Marine Ecosystems After The Late Permian Mass Extinction Event, Wj Foster, Rj Twitchett Jan 2014

Functional Diversity Of Marine Ecosystems After The Late Permian Mass Extinction Event, Wj Foster, Rj Twitchett

School of Geography, Earth and Environmental Sciences

The Late Permian mass extinction event was the most severe such crisis of the past 500 million years and occurred during an episode of global warming. It is assumed to have had significant ecological impact, but its effects on marine ecosystem functioning are unknown and the patterns of marine recovery are debated. We analysed the fossil occurrences of all known Permian-Triassic benthic marine genera and assigned each to a functional group based on their inferred life habit. We show that despite the selective extinction of 62-74% of marine genera there was no significant loss of functional diversity at the global …

Parameterization Of Pharmaceutical Emissions And Removal Rates For Use In Uk Predictive Exposure Models: Steroid Estrogens As A Case Study., J. D. Heffley, S. D.W. Comber, B. W. Wheeler, C. H. Redshaw

School of Geography, Earth and Environmental Sciences

Newly available prescription data has been used along with census data to develop a localised method for predicting pharmaceutical concentrations in sewage influent and effluent for England, and applied to a case study: the steroid estrogens estrone, 17β-estradiol, and 17α-ethinylestradiol in a selected catchment. The prescription data allows calculation of the mass consumed of synthetic estrogens, while use of highly localised census data improves predictions of naturally excreted estrogens by accounting for regional variations in population demographics. This serves two key purposes; to increase the accuracy of predictions in general, and to call attention to the need for more accurate …

Social Networks In Elasmobranchs And Teleost Fishes, A. D.M. Wilson, D. P. Croft, J. Krause Jan 2014

Social Networks In Elasmobranchs And Teleost Fishes, A. D.M. Wilson, D. P. Croft, J. Krause

School of Biological and Marine Sciences

AbstractOver the last decade, there has been an exponential increase in studies using social network analysis to describe the structure of animal societies. In this synthesis, we examine the contribution of social network analysis towards developing our understanding of the social organization of elasmobranchs and teleost fishes. We review and discuss the current state of knowledge of the mechanisms and functions underpinning social network structure in fishes with particular emphasis on cooperation, familiarity, site fidelity, population structure and the welfare of captive populations. We also discuss important methodological issues (e.g. how to identify and mark fish) and highlight new developments …

Nuclear Her4 Mediates Acquired Resistance To Trastuzumab And Is Associated With Poor Outcome In Her2 Positive Breast Cancer, Snm Nafi, D Generali, G Kramer-Marek, M Gijsen, Et Al Jan 2014

Nuclear Her4 Mediates Acquired Resistance To Trastuzumab And Is Associated With Poor Outcome In Her2 Positive Breast Cancer, Snm Nafi, D Generali, G Kramer-Marek, M Gijsen, Et Al

School of Biomedical Sciences

The role of HER4 in breast cancer is controversial and its role in relation to trastuzumab resistance remains unclear. We showed that trastuzumab treatment and its acquired resistance induced HER4 upregulation, cleavage and nuclear translocation. However, knockdown of HER4 by specific siRNAs increased trastuzumab sensitivity and reversed its resistance in HER2 positive breast cancer cells. Preventing HER4 cleavage by a γ-secretase inhibitor and inhibiting HER4 tyrosine kinase activity by neratinib decreased trastuzumab-induced HER4 nuclear translocation and enhanced trastuzumab response. There was also increased nuclear HER4 staining in the tumours from BT474 xenograft mice and human patients treated with trastuzumab. Furthermore, …

Evidence That Duplications Of 22q11.2 Protect Against Schizophrenia, E Rees, G Kirov, Mc O'Donovan, Wellcome Trust Case Control Consortium, Et Al Jan 2014

Evidence That Duplications Of 22q11.2 Protect Against Schizophrenia, E Rees, G Kirov, Mc O'Donovan, Wellcome Trust Case Control Consortium, Et Al

School of Biomedical Sciences

A number of large, rare copy number variants (CNVs) are deleterious for neurodevelopmental disorders, but large, rare, protective CNVs have not been reported for such phenotypes. Here we show in a CNV analysis of 47 005 individuals, the largest CNV analysis of schizophrenia to date, that large duplications (1.5-3.0 Mb) at 22q11.2--the reciprocal of the well-known, risk-inducing deletion of this locus--are substantially less common in schizophrenia cases than in the general population (0.014% vs 0.085%, OR=0.17, P=0.00086). 22q11.2 duplications represent the first putative protective mutation for schizophrenia.

Talking On The Move: Place‐Based Interviewing With Undergraduate Students, Mark Holton, Mark Riley Jan 2014

Talking On The Move: Place‐Based Interviewing With Undergraduate Students, Mark Holton, Mark Riley

School of Geography, Earth and Environmental Sciences

Recent research has begun to pay attention to the importance of place to the research encounter. This paper makes a contribution to these discussions through an investigation into the lived experiences of higher education students. Although there is a burgeoning literature on what has been termed ‘student geographies’, there has been relatively little attention focused on the methods that we might employ in exploring these geographies. Here we consider ‘walking interviews’ as an approach to helping better comprehend students’ experiences and understandings of University towns and cities. Accompanying students ‘in the field’ allowed us to explore students’ narratives ‘in place’ …

Overfishing And The Replacement Of Demersal Finfish By Shellfish: An Example From The English Channel., Carlotta Molfese, Doug Beare, Jason M. Hall-Spencer Jan 2014

Overfishing And The Replacement Of Demersal Finfish By Shellfish: An Example From The English Channel., Carlotta Molfese, Doug Beare, Jason M. Hall-Spencer

School of Biological and Marine Sciences

The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure of marine ecosystems. Here we assess changes in the trophic structure of the English Channel marine ecosystem using a 90-year time-series (1920-2010) of commercial fishery landings. Our analysis was based on estimates of the mean trophic level (mTL) of annual landings and the Fishing-in-Balance index (FiB). Food webs of the Channel ecosystem have been altered, as shown by a significant decline in the mTL of fishery landings whilst increases in the FiB index suggest increased fishing effort and fishery expansion. …

Comparison Of Intermittent And Continuous Exposures To Inorganic Mercury In The Mussel, Mytilus Edulis: Accumulation And Sub-Lethal Physiological Effects., D Amachree, Aj Moody, Rd Handy

School of Biological and Marine Sciences

Aquatic organisms are often subject to intermittent exposure to pollutants in real ecosystems. This study aimed to compare mercury accumulation and the physiological responses of mussels, Mytilus edulis during continuous and intermittent exposure to the metal. Mussels were treated in a semi-static, triplicated design to either a control (no added Hg) or 50 µg l(-1) Hg as HgCl2 in continuous (daily) or intermittent (2 day exposure, 2 days in clean seawater alternately) exposure for 14 days. A time-dependent increase in Hg accumulation was observed in the continuous exposure, while the intermittent treatment showed step-wise changes in Hg concentrations with the …

School of Biological and Marine Sciences

Small, early life stages, such as zebrafish embryos are increasingly used to assess the biological effects of chemical compounds in vivo. However, behavioural screens of such organisms are challenging in terms of both data collection (culture techniques, drug delivery and imaging) and data evaluation (very large data sets), restricting the use of high throughput systems compared to in vitro assays. Here, we combine the use of a microfluidic flow-through culture system, or BioWell plate, with a novel motion analysis technique, (sparse optic flow - SOF) followed by spectral analysis (discrete Fourier transformation - DFT), as a first step towards automating …

Effects Of Dietary Β-(1,3)(1,6)-D-Glucan Supplementation On Growth Performance, Intestinal Morphology And Haemato-Immunological Profile Of Mirror Carp (Cyprinus Carpio L.)., H. Kühlwein, D. L. Merrifield, M. D. Rawling, A. D. Foey, S. J. Davies Jan 2014

Effects Of Dietary Β-(1,3)(1,6)-D-Glucan Supplementation On Growth Performance, Intestinal Morphology And Haemato-Immunological Profile Of Mirror Carp (Cyprinus Carpio L.)., H. Kühlwein, D. L. Merrifield, M. D. Rawling, A. D. Foey, S. J. Davies

School of Biological and Marine Sciences

In recent years, aquaculture research has focused on probiotics, prebiotics, and β-glucans, in order to improve health status and growth performance. Information regarding the effects of β-glucan on growth performance and intestinal immunity of mirror carp (Cyprinus carpio L.) is scarce. An experiment was therefore conducted to investigate the effects of a yeast β-glucan preparation (MacroGard(®) ) on growth performance, intestinal morphology and haemato-immunological indices of mirror carp. Carp (initial weight 11.1 ± 0.0 g) were fed highly purified diets supplemented with 0% (control), 0.1%, 1% or 2% MacroGard(®) for 8 weeks. Fish fed diets containing 1% and 2% MacroGard(®) …

School of Biological and Marine Sciences

There is a paucity of information on the impacts of the 1997-8 El Niño event and subsequent climatic episodes on emergent intertidal coral reef assemblages. Given the environmental variability intertidal reefs experience, such reefs may potentially be more resilient to climatic events and provide important insights into the adaptation of reef fauna to future ocean warming. Here we report the results of a 17-year (1995-2011) biodiversity survey of four emergent coral reef ecosystems in Bahia, Brazil, to assess the impact of a major El Niño event on the reef fauna, and determine any subsequent recovery. The densities of two species …

Variable Response Of Three Trifolium Repens Ecotypes To Soil Flooding By Seawater., Anissia C. White, Timothy D. Colmer, Greg R. Cawthray, Mick E. Hanley

School of Biological and Marine Sciences

BACKGROUND AND AIMS: Despite concerns about the impact of rising sea levels and storm surge events on coastal ecosystems, there is remarkably little information on the response of terrestrial coastal plant species to seawater inundation. The aim of this study was to elucidate responses of a glycophyte (white clover, Trifolium repens) to short-duration soil flooding by seawater and recovery following leaching of salts. METHODS: Using plants cultivated from parent ecotypes collected from a natural soil salinity gradient, the impact of short-duration seawater soil flooding (8 or 24 h) on short-term changes in leaf salt ion and organic solute concentrations was …

Minimal Effects Of Waterborne Exposure To Single-Walled Carbon Nanotubes On Behaviour And Physiology Of Juvenile Rainbow Trout (Oncorhynchus Mykiss)., D Boyle, Je Fox, Jm Akerman, Ka Sloman, Tb Henry, Rd Handy

School of Biological and Marine Sciences

Fish behaviours are often considered to be sensitive endpoints of waterborne contaminants, but little attention has been given to engineered nanomaterials. The present study aimed to determine the locomotor and social behaviours of rainbow trout (Oncorhynchus mykiss) during waterborne exposure to single-walled carbon nanotubes (SWCNTs), and to ascertain the physiological basis for any observed effects. Dispersed stock suspensions of SWCNTs were prepared by stirring in sodium dodecyl sulphate (SDS), an anionic surfactant, on an equal w/w basis. Trout were exposed to control (no SWCNT or SDS), 0.25 mg L(-1) SDS (dispersant control), or 0.25 mg L(-1) of SWCNT for 10 …
