Review Of "The Human Embryonic Stem Cell Debate: Science, Ethics, And Public Policy (Basic Bioethics)," Edited By Suzanne Holland, Karen Lebacqz, And Laurie Zoloth, James Steele Dec 2002

Review Of "The Human Embryonic Stem Cell Debate: Science, Ethics, And Public Policy (Basic Bioethics)," Edited By Suzanne Holland, Karen Lebacqz, And Laurie Zoloth, James Steele

The University of New Hampshire Law Review

[Excerpt] "Perhaps like others, I started "The Human Embryonic Stem Cell Debate" not knowing many of the finer points of embryonic stem cell research, but I certainly had an opinion. This issue is far more complex than I had initially imagined. The editors do a commendable effort of compiling a sample of the innumerable arguments surrounding the debate."

Review Of "The Health Of Nations: Infectious Disease, Environmental Change, And Their Effects On National Security And Development," By Andrew T. Price-Smith, Andrew Mierins

The University of New Hampshire Law Review

[Excerpt] "Andrew T. Price-Smith, author of The Health of Nations: Infectious Disease, Environmental Change, and Their Effects on National Security and Development, provides a well documented and reasoned analysis of the need for world leaders, including the United States, to place the threat of infectious disease on the front burner of consideration when shaping both national and international policy. Professor Price-Smith has provided both empirical data and historical analysis to support the impassioned plea for this natural threat to be taken seriously. The book is geared toward the academic community and policy analysts; however, other professionals not involved in these …

In an email chat with IIMB Management Review, V C Burman talked about the responsibilities of the family in family businesses, the need to professionalise and how Dabur has successfully gone about it. The vital move in tackling all the challenges that professionalisation brought in its wake, he explained, was the establishment of the Family Council. He also touched on the opportunities in the pharmaceutical and ayurvedic sectors, the initiatives Dabur has taken to help improve the quality of ayurvedic products; and its contributions towards conservation and sustainable development. Vivek C Burman, Chairman, Dabur India, is the great grandson of …


Rotational Lift: Something Different Or More Of The Same?, Jeffrey A. Walker Phd Dec 2002

Rotational Lift: Something Different Or More Of The Same?, Jeffrey A. Walker Phd

Faculty Publications

This paper addresses the question, do the rotational forces in the hovering fruit fly Drosophila melanogaster reflect something different (the Magnus effect) or more of the same (circulatory-and-attached-vortex force)? The results of an unsteady blade-element model using empirically derived force coefficients from translating (root-oscillating) wings are compared with recent results derived from both the measured forces on a dynamically scaled Drosophila wing and the computational fluid dynamic (CFD)-modeled forces on a virtual Drosophila wing. The behavior of the forces in all three models during wing rotation supports the hypothesis that rotational lift is not a novel aerodynamic mechanism but is …

Convergent Demographic Effects Of Insect Attack On Related Thistles In Coastal Vs. Continental Dunes, John L. Maron, Julie K. Combs, Svata M. Louda Dec 2002

Convergent Demographic Effects Of Insect Attack On Related Thistles In Coastal Vs. Continental Dunes, John L. Maron, Julie K. Combs, Svata M. Louda

School of Biological Sciences: Faculty Publications

Insect herbivory is common, but the conditions under which it reduces the fitness and population size of plants remain poorly understood. We quantified populationlevel impacts of floral herbivory by specialized insects on cobweb thistle (Cirsium occidentale var. occidentale) in a California coastal dune ecosystem, and then compared these demographic effects to those published for Platte thistle (Cirsium canescens) in similarly designed exclusion experiments in the continental sand dune ecosystem in the Great Plains. As a separate test of the strength of the seed-to-seedling linkage, we quantified seedling establishment rates in seed addition plots and compared these …


16 | Kissufim Road: A Chalcolithic Mortuary Site, Yuval Goren, Peter Fabian Dec 2002

16 | Kissufim Road: A Chalcolithic Mortuary Site, Yuval Goren, Peter Fabian

IAA Reports—Monograph Series of the Israel Antiquities Authority

This volume describes the results of the excavation of a unique mortuary site in the northwestern Negev, which differs from Chalcolithic cave-burial sites known in the coastal plain and northern Israel, and the stone circles known from a few sites in the northwestern Negev and southern Transjordan. The excavations revealed a mortuary site containing some 54 individuals, both children and adults, in secondary burial in ceramic ossuaries, urns, jars, bowls and ceramic and stone burial tubs. Individuals were interred in a rectangular mud-built funerary structure, surrounded by a number of individual pit burials and a collective burial in a large …


A Simple Test To Evaluate The Calibration Stability And Accuracy Of Infrared Thermocouple Sensors, Derek R. Pinnock, Bruce Bugbee Dec 2002

A Simple Test To Evaluate The Calibration Stability And Accuracy Of Infrared Thermocouple Sensors, Derek R. Pinnock, Bruce Bugbee

Techniques and Instruments

Accurately measuring surface temperature is not difficult when the surface, the sensor, and air temperatures are similar, but it is challenging when the surface temperature is significantly different than air and sensor temperatures.

We tested three Infrared Thermocouple sensors (IRT’s) that had been used for two years in a greenhouse environment. The importance of the correction for sensor body temperature was also examined.


Contrasting Patterns Of Divergence In Quantitative Traits And Neutral Dna Markers: Analysis Of Clinal Variation, Jay F. Storz Dec 2002

Contrasting Patterns Of Divergence In Quantitative Traits And Neutral Dna Markers: Analysis Of Clinal Variation, Jay F. Storz

Jay F. Storz Publications

Clinal variation in quantitative traits is often attributed to the effects of spatially varying selection. However, identical patterns can be produced by the interplay between purely stochastic processes (i.e. drift in combination with spatially restricted gene flow). One means of distinguishing between adaptive and nonadaptive causes of geographical variation is to compare relative levels of between population divergence in quantitative traits and neutral DNA markers. Such comparisons can be used to test whether levels of trait divergence attributable to additive genetic effects (as measured by QST) exceed null expectations based on the level of divergence at neutral marker …

Saving Special Places: Community Funding For Land Conservation, Brian Hart, Dorothy Tripp Taylor

PREP Reports & Publications

In New Hampshire communities, there is a groundswell of interest and activity in conserving land. New Hampshire currently has more than forty-five land trusts. There are conservation commissions in all but a handful of towns. Many of them are engaged in conserving their special natural lands. Over half of the towns in the state have conservation funds fueled by the Land Use Change Tax. There have been 62 applications for land conservation projects to the Land and Community Heritage Investment Program since its inception in 2000. New Hampshire voters are appropriating significant taxpayer funds to conserve undeveloped land. Twelve communities, …


Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard Dec 2002

Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard

Nebraska Bird Review

Although the spring concentrations of Sandhill Cranes in Nebraska's Platte Valley are now an avian phenomenon known nationwide, a general appreciation and inventory of this unique concentration of birds has only been attempted in the last few decades. I am often asked how long this largest of all crane concentrations has been occurring in the Platte Valley, and why it has developed only there. Here I will try to summarize the little-known history of this marvelous assemblage, but not dwell on the ecological reasons for it. The latter are now generally well understood to revolve around abundant spring food supplies …

Fall Field Report, August-November 2002, W. Ross Silcock Dec 2002

Fall Field Report, August-November 2002, W. Ross Silcock

Nebraska Bird Review

A few words on documentation of sightings reported is in order. I receive many reports each season of rare or hard-to-identify birds. If they fit a pattern that has developed over the years (see "Birds of Nebraska"), I tend to accept them as correct. However, if they fall outside the range of prior reports, I usually email the observer and ask for some details about the identification and circumstances of the sighting. Everyone has been very nice about this process; observers sometimes take these requests as a questioning of their ability, but I haven't run into this problem with Nebraska …

Both genera belong …


Introduction To Special Issue On Radiation Effects, P. Andrew Karam Dec 2002

Introduction To Special Issue On Radiation Effects, P. Andrew Karam

The University of New Hampshire Law Review

[Excerpt] "How dangerous is radiation? How much radiation does it take to give us cancer? Are we wasting money on overly restrictive regulations, or are we not being sufficiently protective of our radiation workers and the public? How much clean-up is necessary on our Department of Energy facilities? What about Yucca Mountain and nuclear reactor plants – can they be made safe?

These are only a few of the questions that have been asked, and will continue to be asked, about radiation. Unfortunately, these all come down, in part or in whole, to the question “What is the shape of …

Effects Of The Shape Of The Radiation Dose-Response Curve On Public Acceptance Of Radiation And Nuclear Energy, Audeen W. Fentiman Dec 2002

Effects Of The Shape Of The Radiation Dose-Response Curve On Public Acceptance Of Radiation And Nuclear Energy, Audeen W. Fentiman

The University of New Hampshire Law Review

[Excerpt] “The public generally accepts the premise that exposure to radiation can have an undesirable effect. Furthermore, it believes that as the radiation dose increases, the magnitude of the effect will increase. On the other hand, while the background radiation dose varies from a few hundred millirem/year (a few millisieverts/yr) in some places to a few thousand millirem/yr (tens of millisieverts/yr) in others, researchers have been unable to find a correlation between the level of background radiation and incidence of cancer or other maladies attributable to radiation.

…

Because there is considerable controversy about the relationship between radiation dose and …


The Debate On The Health Effects Attributable To Low Radiation Exposure, Abel J. Gonzalez Dec 2002

The Debate On The Health Effects Attributable To Low Radiation Exposure, Abel J. Gonzalez

The University of New Hampshire Law Review

[Excerpt] "Few scientific issues have aroused passions more than the dispute about the health effects attributable to low levels of exposure to ionizing radiation (or radiation in short) and the currently authoritative dose response hypothesis, termed “linear non-threshold,” or LNT. Finding out whether health effects are induced by low-level radiation exposures, and if so, what they are, has become a kind of contest rather than a serious scientific inquiry. Sometimes it seems that rationality, or a methodical examination of the unknown, has disappeared from this debate. While the confrontation of different hypotheses is typical in academic discussions – at least …

A Neural Network Method For Protein Classification, Arie D. Jones Dec 2002

A Neural Network Method For Protein Classification, Arie D. Jones

All-Inclusive List of Electronic Theses and Dissertations

The investigation detailed in this paper attempts to utilize a Leaming Vector Quantization network in order to classify a set of mitochondrial proteins based upon their amino acid sequence. The Learning Vector Quantization network uses a nearest neighbor approach to classification. Input vectors are fed into the network, which produces output vectors. Those output vectors are then matched by means of a distance bias to a corresponding classification vector. The learning and test sets consisted of thirteen similar mitochodrial proteins from seventy-two different species. This provided a pool of over nine hundred proteins to use. Half of the species were …
