Cross-Life Stage Effects Of Aquatic Larval Density And Terrestrial Moisture On Growth And Corticosterone In The Spotted Salamander, Julie F. Charbonnier, Jacquelyn Pearlmutter, James R. Vonesh, Caitlin R. Gabor, Zachery R. Forsburg, Kristine L. Grayson Jul 2018

Cross-Life Stage Effects Of Aquatic Larval Density And Terrestrial Moisture On Growth And Corticosterone In The Spotted Salamander, Julie F. Charbonnier, Jacquelyn Pearlmutter, James R. Vonesh, Caitlin R. Gabor, Zachery R. Forsburg, Kristine L. Grayson

Biology Faculty Publications

For organisms with complex life cycles, conditions experienced during early life stages may constrain later growth and survival. Conversely, compensatory mechanisms may attenuate negative effects from early life stages. We used the spotted salamander, Ambystoma maculatum, to test how aquatic larval density and terrestrial moisture influence juvenile growth, food intake, evaporative water loss and water reuptake rates, and corticosterone levels. We conducted an outdoor mesocosm experiment to manipulate larval density and transferred metamorphosed salamanders into low and high terrestrial moisture treatments in laboratory terrariums. After the larval stage, high-density salamanders were significantly smaller and had higher corticosterone release rates than ...


Thermal Physiology And Developmental Plasticity Of Pigmentation In The Harlequin Bug (Hemiptera: Pentatomidae), Carly D. Sibilia, Kelly A. Brosko, Christopher J. Hickling, Lily M. Thompson, Kristine L. Grayson, Jennifer R. Olson Jul 2018

Thermal Physiology And Developmental Plasticity Of Pigmentation In The Harlequin Bug (Hemiptera: Pentatomidae), Carly D. Sibilia, Kelly A. Brosko, Christopher J. Hickling, Lily M. Thompson, Kristine L. Grayson, Jennifer R. Olson

Biology Faculty Publications

Traits that promote the maintenance of body temperatures within an optimal range provide advantages to ectothermic species. Pigmentation plasticity is found in many insects and enhances thermoregulatory potential as increased melanization can result in greater heat retention. The thermal melanism hypothesis predicts that species with developmental plasticity will have darker pigmentation in colder environments, which can be an important adaptation for temperate species experiencing seasonal variation in climate. The harlequin bug (Murgantia histrionica, Hemiptera: Pentatomidae, Hahn 1834) is a widespread invasive crop pest with variable patterning where developmental plasticity in melanization could affect performance. To investigate the impact of temperature ...


Cattle As Technological Interventions: The Gender Effects Of Water Demand In Dairy Production In Uganda, Elizabeth Ransom, Carmen Bain, Harleen Bal, Natasha Shannon Sep 2017

Cattle As Technological Interventions: The Gender Effects Of Water Demand In Dairy Production In Uganda, Elizabeth Ransom, Carmen Bain, Harleen Bal, Natasha Shannon

Sociology and Anthropology Faculty Publications

Smallholder dairy production dominates the country of Uganda, with over 90% of the national herd owned by smallholders. To reduce hunger, malnutrition, and raise families out of poverty agricultural development, interventions in Uganda have focused on increasing milk production through the introduction of improved dairy cow breeds. Development actors, such as the East Africa Dairy Development (EADD) program in Uganda, see crossbreed dairy cows as a key technological intervention for improving production. Drawing on a multi-method study (spatial analysis, surveys, and qualitative interviews) of dairy smallholders, our paper examines the gendered effects of the introduction of crossbreed dairy cows. To ...


The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá Jun 2014

The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá

Biology Faculty Publications

Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life.

Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the ...


Predictability And Nonobviousness In Patent Law After Ksr, Christopher A. Cotropia Jan 2014

Predictability And Nonobviousness In Patent Law After Ksr, Christopher A. Cotropia

Law Faculty Publications

In KSR International Co. v. Teleflex, Inc., the Supreme Court addressed the doctrine of nonobviousness, the ultimate question of patentability, for the first time in thirty years. In mandating a flexible approach to deciding nonobviousness, the KSR opinion introduced two predictability standards for determining nonobviousness. The Court described predictability of use (hereinafter termed "Type I predictability" )-whether the inventor used the prior art in a predictable manner to create the invention-and predictability of the result (hereinafter termed "Type II predictability")-whether the invention produced a predictable result-both as a means for proving obviousness. Although Type I predictability is easily explained ...


Hydropower, Mary Finley-Brook Jan 2014

Hydropower, Mary Finley-Brook

Geography and the Environment Faculty Publications

Hydropower dates back to the use of waterwheels to grind grain in Greece over two thousand years ago. Modern hydropower is a mature industry that has been used to generate electricity since the 1880s by capturing flowing water with a dam or other diversion structure and channeling it through a waterwheel or turbine. According to a 2012 report by the International Energy Agency, internationally dams are responsible for the largest amount of power generation from a renewable source; yet they have come under scrutiny as a result of environmental and social impacts perceived to be unsustainable (McCully 2001). Specific impacts ...


Ethnoracial Land Restitution: Finding Indians And Fugitive Slave Descendants In The Brazilian Northeast, Jan Hoffman French Jan 2009

Ethnoracial Land Restitution: Finding Indians And Fugitive Slave Descendants In The Brazilian Northeast, Jan Hoffman French

Sociology and Anthropology Faculty Publications

This chapter considers how a desire for land and development can lead to a refashioning of ethnoracial identities and identifications. Debates in development studies have centered on culture as an impediment to development. I turn that debate on its head and argue that new assertions of cultural particularity have in certain settings advanced the equity goals of development. The chapter explores the contrasting responses of two neighbouring communities of related African descended, mixed race rural workers who over a 25-year period (1975- 2000), under new laws, were recognized and given land by the Brazilian government. One was identified as an ...


Psychology, David E. Leary Jan 2006

Psychology, David E. Leary

Psychology Faculty Publications

Psychology, in a general sense, is age-old, extending back across all cultures to the beginnings of recorded time. The healing arts of ancient doctors and the conceptual musings of ancient sages often pointed toward factors that would be considered psychological today. Nevertheless, psychology in its specifically modern sense dates from the second half of the nineteenth century, when a self-consciously scientific, academic, professional discipline took shape in Europe and North America. This multiplex discipline grew and flourished in particular in the United States, where more than forty experimental laboratories, associated programs of research and study, and institutionalized means of communication ...


Mediation And The Transformation Of American Labor Unions, Ann C. Hodges Apr 2004

Mediation And The Transformation Of American Labor Unions, Ann C. Hodges

Law Faculty Publications

First, the Article analyzes in more detail the changes in the workplace that have led to various proposals for reform. Then the Article looks at the potential for mediation of claims that do not arise out of the collective bargaining agreement, analyzing the possible benefits from the point of view of employers, employees and unions. Next, some of the issues and obstacles to mediation are reviewed. Ultimately the Article concludes that the benefits of mediation outweigh the disadvantages and that in most collective bargaining relationships the obstacles should not prevent either negotiation of such provisions or their successful use for ...


A Tale Of Two Families: Change In North Yemen 1977-1989, Sheila Carapico, Cynthia Myntti Jan 1991

A Tale Of Two Families: Change In North Yemen 1977-1989, Sheila Carapico, Cynthia Myntti

Political Science Faculty Publications

Virtually every aspect of life in North Yemen has changed dramatically since 1977, including those aspects of Yemeni society which represent continuity with the past: tribalism, rural life, and use of qat.1 The driving force for change has been economic. By 1975, Yemen was caught up in the dramatic developments that affected all Arab countries. Rising international oil prices generated enormous surpluses in the producing countries, enabling them to initiate ambitious development plans and forcing them to import workers.

The Yemen Arab Republic (YAR) was in a good position to provide those workers. In the late 1970s, one of ...


A Profile Of Research In Expert Systems, Mohammed H. Omar, Jack S. Goodwin Jan 1989

A Profile Of Research In Expert Systems, Mohammed H. Omar, Jack S. Goodwin

Robins School of Business White Paper Series, 1980-2011

If the field of Expert Systems (ES) is viewed in terms of a life cycle, the past decade represents the growth phase of its development. Sophistication of ES has increased rapidly, and the use of ES to solve more complex problems has maintained a similar pace. Numerous forces have driven this development including the rapid changes in computer technology. As the field has matured, the body of published research in ES has grown substantially.

Through the use of published ES research, this article provides useful answers to these questions. The scope of our study is limited to the description and ...


Immanuel Kant And The Development Of Modern Psychology, David E. Leary Jan 1982

Immanuel Kant And The Development Of Modern Psychology, David E. Leary

Psychology Faculty Publications

Few thinkers in the history of Western civilization have had as broad and lasting an impact as Immanuel Kant (1724-1804). This "Sage of Konigsberg" spent his entire life within the confines of East Prussia, but his thoughts traveled freely across Europe and, in time, to America, where their effects are still apparent. An untold number of analyses and commentaries have established Kant as a preeminent epistemologist, philosopher of science, moral philosopher, aesthetician, and metaphysician. He is even recognized as a natural historian and cosmologist: the author of the so-called Kant-Laplace hypothesis regarding the origin of the universe. He is less ...


Brazil's Profit Remittance Law: Reconciling Goals In Foreign Investments, Jan Hoffman French Jan 1982

Brazil's Profit Remittance Law: Reconciling Goals In Foreign Investments, Jan Hoffman French

Sociology and Anthropology Faculty Publications

Promoting foreign investment is a goal of many developing nations. Along with the benefits of that investment, however, foreign participation in development creates problems such as balance of payments deficits caused by the repatriation of profits earned by the foreign investor. Brazil's profit remittance law is one effort to reconcile these problems. By providing for the registration of foreign investment and using a system of reinvestment incentives, the Profit Remittance Law seeks to promote foreign investment while avoiding the loss of capital which results when profits are remitted abroad. The author of this article describes and explains the Profit ...
