An Evaluation Of The Us High Production Volume (Hpv) Chemical-Testing Programme: A Study In (Ir)Relevance, Redundancy And Retro Thinking, Andrew Nicholson, Jessica Sandler, Troy Seidle

Troy Seidle, PhD

Under the US Environmental Protection Agency (EPA) High Production Volume (HPV) Challenge Programme, chemical companies have volunteered to conduct screening-level toxicity tests on approximately 2800 widely-used industrial chemicals. Participating companies are committed to providing available toxicity information to the EPA and presenting testing proposals for review by the EPA and posting on the EPA Web site as public information. People for the Ethical Treatment of Animals (PETA) and a coalition of animal protection organisations have reviewed all the test plans submitted by the participating chemical companies for compliance with the original HPV framework, as well as with animal welfare guidelines …


A Modular One-Generation Reproduction Study As A Flexible Testing System For Regulatory Safety Assessment, Richard Vogel, Troy Seidle, Horst Spielmann Dec 2014

A Modular One-Generation Reproduction Study As A Flexible Testing System For Regulatory Safety Assessment, Richard Vogel, Troy Seidle, Horst Spielmann

Troy Seidle, PhD

The European Union’s Registration, Evaluation and Authorisation of Chemicals (REACH) legislation mandates testing and evaluation of approximately 30,000 existing substances within a short period of time, beginning with the most widely used “high production volume” (HPV) chemicals. REACH testing requirements for the roughly 3000 HPV chemicals specify three separate tests for reproductive toxicity: two developmental toxicity studies on different animal species (OECD Test Guideline 414) and a two-generation reproduction toxicity study (OECD TG 416). These studies are highly costly in both economic and animal welfare terms. OECD TG 416 is a fertility study intended to evaluate reproductive performance of animals …

The Fine-Scale Habitat Use Of Risso’S Dolphins Off Bardsey Island, Cardigan Bay (Uk), Marijke N. De Boer, Sonja Eisfeld, Mark P. Simmonds

Mark P. Simmonds, OBE

The main objectives of this study were (1) to estimate the population size of Risso’s dolphins off Bardsey Island using mark-recapture techniques (De Boer et al., 2013); and (2) to study habitat-use in relation to fine-scale oceanographic features. This work provides preliminary information on the habitat-use of Risso’s dolphins and will benefit future studies, along with the development of effective conservation measures for this species throughout the region.


Cetaceans And Marine Debris: The Great Unknown, Mark Peter Simmonds Dec 2014

Cetaceans And Marine Debris: The Great Unknown, Mark Peter Simmonds

Mark P. Simmonds, OBE

Plastics and other marine debris have been found in the gastrointestinal tracts of cetaceans, including instances where large quantities of material have been found that are likely to cause impairment to digestive processes and other examples, where other morbidity and even death have resulted. In some instances, debris may have been ingested as a result of the stranding process and, in others, it may have been ingested when feeding. Those species that are suction or “ram” feeders may be most at risk. There is also evidence of entanglement of cetaceans in marine debris. However, it is usually difficult to distinguish …


Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds Dec 2014

Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds

Mark P. Simmonds, OBE

During offshore and onshore studies (2004 to 2009), the interactions between pair-trawls and short-beaked common dolphins (Delphinus delphis) were studied to better understand the impact of bycatch. A ‘hotspot’ area where pair-trawls overlapped with high dolphin abundance was identified. We made comparisons between boat-based data collected in absence and presence of pair-trawlers. The relative abundance and group-size of dolphins was significantly higher in the presence of pair-trawlers. Dolphins were observed associating with towing and hauling procedures. Significantly, more carcasses occurred in areas with hauling-activity than those without. Body-temperatures obtained from carcasses found near operating pair-trawlers indicated that bycatch mostly occurred …

Developing Professional Skills In Stem Students: Data Information Literacy, Lisa Zilinski, Megan R. Sapp Nelson, Amy S. Van Epps

Lisa Zilinski

Undergraduate STEM students are increasingly expected to have some data use skills upon graduation, whether they pursue post-graduate education or move into industry. This project was an initial foray into the application of data information literacy competencies to training undergraduate students to identify markers of data and information quality. The data consumer training appeared within two courses to help students evaluate data objects, including databases and datasets available on the Internet. The application of the Data Credibility Checklist provides a foundation for developing data reuse competencies. Based upon the initial presentation of the content, it became obvious that students need …


Health Professionals’ Roles In Animal Agriculture, Climate Change, And Human Health, Aysha Z. Akhtar, Michael Greger, Hope Ferdowsian, Erica Frank Dec 2014

Health Professionals’ Roles In Animal Agriculture, Climate Change, And Human Health, Aysha Z. Akhtar, Michael Greger, Hope Ferdowsian, Erica Frank

Michael Greger, MD, FACLM

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …


In Service For Sharing: Leadership And Leader - Follower Relationship Factors As Influencers Of Tacit Knowledge Sharing In The It Industry, Billy Whisnant, Odai Khasawneh Nov 2014

In Service For Sharing: Leadership And Leader - Follower Relationship Factors As Influencers Of Tacit Knowledge Sharing In The It Industry, Billy Whisnant, Odai Khasawneh

Odai Khasawneh

Tacit knowledge is an organizational resource that is difficult to cultivate. It requires that responsible agents in the organization take an active role in encouraging trust and the development of relationships where individuals feel that their voice will be heard and that there will be a benefit from them passing knowledge onto someone else. In knowledge work tacit knowledge is especially important. 

This research found that servant leadership is an important factor in influencing tacit knowledge sharing, however leader-member exchange is a factor that will strongly support the sharing of tacit knowledge. 

If there is a dearth in servant leadership, …


Volunteer Studies In Pain Research — Opportunities And Challenges To Replace Animal Experiments: The Report And Recommendations Of A Focus On Alternatives Workshop, C. K. Langley, Q. Aziz, C. Bountra, N. Gordon, P. Hawkins, A. Jones, G. Langley, T. Nurmikko, I. Tracey Nov 2014

Volunteer Studies In Pain Research — Opportunities And Challenges To Replace Animal Experiments: The Report And Recommendations Of A Focus On Alternatives Workshop, C. K. Langley, Q. Aziz, C. Bountra, N. Gordon, P. Hawkins, A. Jones, G. Langley, T. Nurmikko, I. Tracey

Gill Langley, PhD

Despite considerable research, effective and safe treatments for human pain disorders remain elusive. Understanding the biology of different human pain conditions and researching effective treatments continue to be dominated by animal models, some of which are of limited value. British and European legislation demands that non-animal approaches should be considered before embarking on research using experimental animals. Recent scientific and technical developments, particularly in human neuroimaging, offer the potential to replace some animal procedures in the study of human pain. A group of pain research experts from academia and industry met with the aim of exploring creatively the tools, strategies …


The Validity Of Animal Experiments In Medical Research, Gill Langley Nov 2014

The Validity Of Animal Experiments In Medical Research, Gill Langley

Gill Langley, PhD

Other animals, such as mice, rats, rabbits, dogs and monkeys, are widely used as surrogates for humans in fundamental medical research. This involves creating disorders in animals by chemical, surgical or genetic means, with the aim of mimicking selected aspects of human illnesses. It is a truism that any model or surrogate is not identical to the target being modelled. So, in medical research, experiments using animals or cell cultures or even healthy volunteers instead of patients (being the target population with the target illness) will inevitably have limitations, although these will be greater or lesser depending on the model.

The Ups And Downs Of Knowledge Infrastructures In Science: Implications For Data Management, Christine L. Borgman, Peter T. Darch, Ashley E. Sands, Jillian C. Wallis, Sharon Traweek

Christine L. Borgman

The promise of technology-enabled, data-intensive scholarship is predicated upon access to knowledge infrastructures that are not yet in place. Scientific data management requires expertise in the scientific domain and in organizing and retrieving complex research objects. The Knowledge Infrastructures project compares data management activities of four large, distributed, multidisciplinary scientific endeavors as they ramp their activities up or down; two are big science and two are small science. Research questions address digital library solutions, knowledge infrastructure concerns, issues specific to individual domains, and common problems across domains. Findings are based on interviews (n=113 to date), ethnography, and other analyses of …

Luca De Benedictis

In this paper we explore the BACI-CEPII database using Network Analysis. Starting from the visualization of the World Trade Network, we then define and describe the topology of the network, both in its binary version and in its weighted version, calculating and discussing some of the commonly used network’s statistics. We finally discuss some specific topic that can be studied using Network Analysis and International Trade data, both at the aggregated and sectoral level. The analysis is done using multiple software (Stata, R, and Pajek). The scripts to replicate part of the analysis are included in the appendix, and can …


Evidence Of Enso Mega-Drought Triggered Collapse Of Prehistory Aboriginal Society In Northwest Australia, Hamish Mcgowan, Samuel K. Marx, P Moss, Andrew Hammond Aug 2014

Evidence Of Enso Mega-Drought Triggered Collapse Of Prehistory Aboriginal Society In Northwest Australia, Hamish Mcgowan, Samuel K. Marx, P Moss, Andrew Hammond

Samuel K Marx

The Kimberley region of northwest Australia contains one of the World's largest collections of rock art characterised by two distinct art forms; the fine featured anthropomorphic figures of the Gwion Gwion or Bradshaw paintings, and broad stroke Wandjina figures. Luminescence dating of mud wasp nests overlying Gwion Gwion paintings has confirmed an age of at least 17,000 yrs B.P. with the most recent dates for these paintings from around the mid-Holocene (5000 to 7000 yrs B.P.). Radiocarbon dating indicates that the Wandjina rock art then emerged around 3800 to 4000 yrs B.P. following a hiatus of at least 1200 yrs. …


Dust Transport And Deposition In A Superhumid Environment, Samuel K. Marx, Hamish A. Mcgowan Aug 2014

Dust Transport And Deposition In A Superhumid Environment, Samuel K. Marx, Hamish A. Mcgowan

Samuel K Marx

Contemporary rates of dust deposition monitored along a 300-km section of the superhumid West Coast of New Zealand's South Island are presented. In this setting, dust is entrained primarily from the dry channels of braided glaciofluvial rivers that drain the western slopes of the Southern Alps. Measured dust deposition ranged between 0.21 and 118.9 kg-1 ha -1 month-1, which is similar to dust deposition rates monitored in arid and semiarid environments. However, these are not considered to be sufficient for present day loess genesis. Dust deposition was highest in summer because of the greater frequency of favourable dust transporting winds, …


Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm Aug 2014

Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm

Samuel K Marx

Evidence of solar and tropical‐ocean forcing of climate cycles has been found in numerous palaeoclimate records. Numerical modelling studies show physical mechanisms by which direct and indirect solar forcing may affect climate, while there is mounting evidence of solar forcing of tropical ocean‐atmosphere teleconnections. This study has developed a 6500 year record of dust deposition, a proxy for regional hydroclimate variability for the Snowy Mountains region of Australia. Spectral analysis of the record provides evidence of statistically significant cycles in dust deposition of 35–43 years, 62–73 years, 161 years and 2200 years. These correlate with variability in solar irradiance and …


Evolving An Information Systems Capstone Course To Align With The Fast Changing Singapore Marketplace, Chris Boesch, Benjamin Kok Siew Gan Jul 2014

Evolving An Information Systems Capstone Course To Align With The Fast Changing Singapore Marketplace, Chris Boesch, Benjamin Kok Siew Gan

Chris BOESCH

Every year, around fifty-five undergraduate teams of four to six students are required to complete a capstone course for the School of Information Systems at Singapore Management University. Each team spends approximately five months working with an industry sponsor using the latest tools and techniques. Students actively learn by implementing the system to solve a real world problem. In addition to delivering value to the local sponsor, our students learn specialized skills currently needed in the marketplace, which might not yet be incorporated into electives and core courses. In this paper, we discuss the tradeoffs of providing students and project …


Automated Library Recommendation, Ferdian Thung, David Lo, Julia Lawall Jun 2014

Automated Library Recommendation, Ferdian Thung, David Lo, Julia Lawall

David LO

Many third party libraries are available to be downloaded and used. Using such libraries can reduce development time and make the developed software more reliable. However, developers are often unaware of suitable libraries to be used for their projects and thus they miss out on these benefits. To help developers better take advantage of the available libraries, we propose a new technique that automatically recommends libraries to developers. Our technique takes as input the set of libraries that an application currently uses, and recommends other libraries that are likely to be relevant. We follow a hybrid approach that combines association …


Mechanisms For Arranging Ride Sharing And Fare Splitting For Last-Mile Travel Demands, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau Jun 2014

Mechanisms For Arranging Ride Sharing And Fare Splitting For Last-Mile Travel Demands, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau

Shih-Fen CHENG

A great challenge of city planners is to provide efficient and effective connection service to travelers using public transportation system. This is commonly known as the last-mile problem and is critical in promoting the utilization of public transportation system. In this paper, we address the last-mile problem by considering a dynamic and demand-responsive mechanism for arranging ride sharing on a non-dedicated commercial fleet (such as taxis or passenger vans). Our approach has the benefits of being dynamic, flexible, and with low setup cost. A critical issue in such ride-sharing service is how riders should be grouped and serviced, and how …


Transportation Safety And Access: A Case Study Of The St. Claude Bridge In New Orleans, Earthea Nance Jun 2014

Transportation Safety And Access: A Case Study Of The St. Claude Bridge In New Orleans, Earthea Nance

Earthea Nance, PhD (Stanford University, 2004)

The community-university collaborative model, first developed in early-1990s public health research, expands opportunities for new research partnerships and joint problem-solving. This model is ideally suited to land-grant colleges and urban research universities whose mission involves community engagement. At the University of New Orleans, this model is employed in “practicum” graduate courses offered in the Department of Planning and Urban Studies. One such practicum partnered with the Lower 9th Ward community in spring 2012 to address serious safety problems with the St. Claude Bridge. The bridge, which linked the lower and upper halves of the community and served as an essential …

Understanding The Influence Of Blog On The Development Of Social Capital, Reza Vaezi, Gholamreza Torkzadeh, Jerry Cha-Jan Chang

Reza Vaezi

The rapid use and application of blogs in diverse areas such as education, marketing, journalism, and human resource management in recent years underlines the need for a better understanding of the impact of this new technology on social capital. Social capital reflects the norm of reciprocity and the level of trust among individuals who connect, interact, and benefit from one another. Blog is expected to influence the extent and the scope of this interaction by providing new means of networking among people. This paper examines the relationship between blog use and social capital and reports on the results of an …


The Public Health Impacts Of Concentrated Animal Feeding Operations On Local Communities, Michael Greger, Gowri Koneswaran May 2014

The Public Health Impacts Of Concentrated Animal Feeding Operations On Local Communities, Michael Greger, Gowri Koneswaran

Michael Greger, MD, FACLM

Large-scale farm animal production facilities, also known as concentrated animal feeding operations (CAFOs), release a significant amount of contaminants into the air and water. Adverse health effects related to exposure to these contaminants among CAFO workers have been welldocumented; however, less is known about their impact on the health of residents in nearby communities. Epidemiological research in this area suggests that neighboring residents are at increased risk of developing neurobehavioral symptoms and respiratory illnesses, including asthma. Additional research is needed to better understand community-scale exposures and health outcomes related to the management practices and emissions of CAFOs.


Laboratory Routines Cause Animal Stress, Jonathan P. Balcombe, Neal D. Barnard, Chad Sandusky May 2014

Laboratory Routines Cause Animal Stress, Jonathan P. Balcombe, Neal D. Barnard, Chad Sandusky

Jonathan Balcombe, PhD

Eighty published studies were appraised to document the potential stress associated with three routine laboratory procedures commonly performed on animals: handling, blood collection, and orogastric gavage. We defined handling as any non-invasive manipulation occurring as part of routine husbandry, including lifting an animal and cleaning or moving an animal's cage. Significant changes in physiologic parameters correlated with stress (e.g., serum or plasma concentrations of corticosterone, glucose, growth hormone or prolactin, heart rate, blood pressure, and behavior) were associated with all three procedures in multiple species in the studies we examined. The results of these studies demonstrated that animals responded with …


Failed Cyberdefense - The Environmental Consequences Of Hostile Acts, Jan Kallberg, Rosemary A. Burk May 2014

Failed Cyberdefense - The Environmental Consequences Of Hostile Acts, Jan Kallberg, Rosemary A. Burk

Jan Kallberg

A failed cyberdefense can have wider effects than discussed in earlier debates of potential consequences of a cyberattack. The need for cyberdefense to protect the environment has not drawn the attention it deserves as a national security matter. Adversarial nations are covertly pursuing methods to damage and disrupt the United States in a cyberconflict in the future. The president of the United States noted this in Sustaining U.S. Global Leadership: Priorities for 21st Century Defense: Both state and non-state actors possess the capability and intent to conduct cyberespionage and, potentially, cyberattacks on the United States, with possible severe effects on …

Magnitude Of Floods And Its Consequences In Puthimari River Basin Of Assam, India, Pankaj Roy

Pankaj Roy

The main aim of the present study is to analyse the magnitude and consequences of floods in the Puthimari River Basin of Assam, particularly from the second half of the 20th century to the 1st decade of the 21st century. An attempt has been made to study floods from 1958 to 2008. The hydrological data such as water level and water discharge have been collected from two different sources depending on its availability. The stage hydrographs have been prepared using maximum and minimum water level. The magnitude of floods has been identified by comparing the maximum stage hydrograph and danger …


The Role Of Geospatial Technology In Bridging The Gap Between Physical And Human Geography, Pankaj Roy Apr 2014

The Role Of Geospatial Technology In Bridging The Gap Between Physical And Human Geography, Pankaj Roy

Pankaj Roy

The interaction between physical and human geography is obvious as both are two sub disciplines of parent subject Geography. But it has been felt that the gap between the two sub disciplines has been increasing as time passed. It has been tried to seek answer of the question that why the gap between these two sister disciplines has been increasing day by day putting the Tobler’s first law of Geography, ‘Everything is related to everything else, but near things are more related than distant things’ as the base statement in the growth of specialization also. If we follow the first …


New Data On Occurrences Of The Devonian Rugose Coral Calceola In Belgium, Anthony J. Wright, M Coen-Aubert, P Bultynck, A P. Van Viersen Apr 2014

New Data On Occurrences Of The Devonian Rugose Coral Calceola In Belgium, Anthony J. Wright, M Coen-Aubert, P Bultynck, A P. Van Viersen

Anthony Wright

Opercula and corallites of Calceola sandalina from the late Eifelian and early Givetian (Middle Devonian) Hanonet Formation of Belgium are illustrated. The few previous illustrations of calceoloid corals from the Devonian of Belgium did not include opercula showing the generically diagnostic morphological features, so for the first time the presence of the genus and species in Belgium is confirmed. One important corallite shows the alar septum and insertion of septa on the external surface of the counter face adjacent to the alar septum.
