Distance Education is an increasingly common educational delivery method. At Old Dominion University, all junior and senior level engineering technology courses are offered via distance education at least once every two years. A majority of courses in the distance education system at this university have three simultaneous delivery methods: on-campus, televised (receiving the course at an off-campus site via satellite video/audio), and internet-based video-streamed.

This paper explores the results of student course evaluation surveys for trends, in particular those trends which can be a result of the mode of delivery. Results of these surveys for 23 courses over a 4-year …

Demonstrating Sustainable Farm Management Systems. Final Report For Rcg05-Ord13, Tara Slaven, Francis Bright, Jodie Hawley, Joe Sherrard

Natural resources research reports

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.

The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.

The aim of this project was to develop and demonstrate …

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven

Bulletins 4000 -

The main barrier to the adoption of PAM seems to the timing of the cost of outlay. This could add significantly to the initial crop establishment costs at a time of year when rowers receive no income. However, the partial and parametric analysis indicates that there re benefits from using PAM as part of the crop management cycle. These benefits are from ving water, retaining sediment on-farm and reducing the cost of delving drains. There are ther potential economic benefits including the retainment of phosphorus as a plant nutrient n-farm and subsequent yield increases.

Additionally, the off-site environmental impacts seem …

The Transformation Of Work, The Disappearance Of 'Workers', And The Future Of Workplace Regulation, Harry W. Arthurs

All Papers

If you have read my curriculum vitae you will not have seen the publication that inspires my remarks this evening. As I was waiting to go off to Harvard to do my master‟s degree, I was offered work revising a publication known as the Canadian Encyclopaedic Digest. In particular I was asked to update the chapter on “street railways” - what you would likely call “trams”. Sections of the chapter covered such illuminating topics as “sounding the gong” and “using the cowcatcher”. It was boring, stupid work, but I had to do It for money. What added injury to insult, …

African Wetlands Of International Importance: Assessment Of Benefits Associated With Designations Under The Ramsar Convention, Royal C. Gardner, Kim Diana Connolly, Abou Bamba

Journal Articles

A party to the Ramsar Convention on Wetlands must designate at least one site within its territory as a Wetland of International Importance. To assess the benefits associated with these international designations, the authors conducted a survey of 26 Ramsar sites in 18 countries in Africa. After a brief introduction to the Ramsar Convention, the article describes the sites that were surveyed, focusing on the ecosystem services they provide and the challenges they face. The article then examines how the sites are identified with the Ramsar Convention and found that designation provided benefits such as: increased support for protection and …

How Do Animal Mitochondria Tolerate Water Stress?, Michael Menze, Steven Hand

Faculty and Staff Scholarship

The vast majority of animal species do not tolerate severe water stress, but the encysted embryo of the brine shrimp Artemia franciscana is an exceptionally useful organism to investigate physiological mechanisms for enduring extreme environmental insults. Any substantial reduction in cellular water poses a threat to survival. Nevertheless anhydrobiotic animals survive virtually complete loss of cellular water. The mechanisms that govern “life without water” (anhydrobiosis) are still not well understood. With certain exceptions, it seems that a recurring strategy for tolerating severe water loss involves the accumulation of both low molecular weight solutes (e.g. trehalose or other polyol) and highly …

Copyright, Trademark And Secondary Liability After Grokster, Mark Bartholomew

Journal Articles

Even though secondary infringement doctrine in both copyright and trademark stems from the same common law starting points, the doctrines have moved in very different directions, particularly in the last decade. As copyright litigants expanded their litigation strategy to include online intermediaries, secondary copyright liability was stretched to encompass a wider array of defendants with increasingly tangential relationships to the direct infringer. Meanwhile, even though similar online threats jeopardized the ability of trademark holders to safeguard their brands' goodwill, courts refused to implement a similar expansion for secondary trademark liability. Although courts are aware of this doctrinal double standard, they …

Contributory Infringers And Good Samaritans, Mark Bartholomew

Journal Articles

The introduction of online technologies has put increased pressure on the doctrine of contributory infringement as intellectual property rights holders switch their attention from direct infringers to Internet intermediaries. The Supreme Court has instructed lower courts to evaluate contributory infringement in light of traditional tort law. The common law of aiding and abetting, however, is so inconsistent as to offer no real guidance. A better approach lies in a separate but related area of tort doctrine. In a limited number of circumstances, tort law recognizes a duty to protect third parties from the actions of others. Like aiding and abetting, …

Cops, Robbers, And Search Engines: The Questionable Role Of Criminal Law In Contributory Infringement Doctrine, Mark Bartholomew

Journal Articles

Online technologies have created a new litigation locus for intellectual property rights holders, one that targets intermediaries, not direct infringers. This unprecedented litigation strategy has put sudden pressure on the courts to evaluate the liability of indirect infringers. Without a developed body of precedent at their disposal, judges have resorted to analogies from the criminal law of accomplice liability to set the boundaries of contributory infringement. Does it make sense for intellectual property regulation to depend on the same principles that animate criminal law? This Article maintains that it would be a mistake to remake contributory infringement law in criminal …

Private Import Safety Regulation And Transnational New Governance, Errol E. Meidinger

Contributions to Books

Published as Chapter 12 in Import Safety: Regulatory Governance in the Global Economy, Cary Coglianese, Adam M. Finkel & David Zaring, eds.

This paper examines the role of ‘private’ (non-governmental) regulatory programs in assuring the safety of imported products. Focusing particularly on food safety it argues that private regulatory institutions have great capacity to control safety hazards and to implement dynamic systems for detecting and correcting nascent risks. However, to establish the accountability and legitimacy relationships necessary for long-term effectiveness, private safety regulatory programs must devise new ways of incorporating and responding to the interests of developing country producers, laborers, …
