A Partial Inventory Of Islands In North Dakota: Potential For Breeding Waterfowl Management, Michael L. Szymanski
A Partial Inventory Of Islands In North Dakota: Potential For Breeding Waterfowl Management, Michael L. Szymanski
The Prairie Naturalist
Islands can provide secure nesting habitat for ducks and other waterbirds, especially in agriculturally dominated landscapes. I inventoried natural and man-made islands in the portion of North Dakota covered by the Prairie Pothole Joint Venture (PPJV). I mapped 1,305 islands in this area; up to 46% of which could provide enhanced nest success with management (e.g., predator removal or establishment of brushy cover). Management of islands for breeding ducks may be an important method for achieving desired reproductive rates in the PP JV as substantial areas of perennial grass cover are lost from federal conservation programs, primarily the Conservation Reserve …

Convergenceconcepts: An R Package To Investigate Various Modes Of Convergence, Pierre Lafaye De Micheaux, Benoit Liquet
The R Journal
ConvergenceConcepts is an R pack age, built upon the tkrplot, tcltk and lattice packages, designed to investigate the convergence of simulated sequences of random variables. Four classical modes of convergence may be studied, namely: almost sure convergence (a.s.), convergence in probability (P), convergence in law (L) and convergence in r-th mean (r). This investigation is performed through ac curate graphical representations. This package may be used as a pedagogical tool. It may give students a better understanding of these notions and help them to visualize these difficult theoretical concepts. Moreover, …
Expression Artifact With Retroviral Vectors Based On Pbmn, Yoshitaka Fukunaga, Robert A. Svoboda, Ronald Cerny, Keith R. Johnson, Margaret J. Wheelock
Expression Artifact With Retroviral Vectors Based On Pbmn, Yoshitaka Fukunaga, Robert A. Svoboda, Ronald Cerny, Keith R. Johnson, Margaret J. Wheelock
Ronald Cerny Publications
While characterizing various splice forms of p120 catenin, we observed what appeared to be a novel posttranslational modification of p120, resulting in a higher molecular weight form that was dependent on the splicing pattern. Further investigation revealed the higher molecular weight form to be a fusion protein between sequences encoded by the retroviral vector and p120. We found that the publicly available sequence of the vector we used does not agree with the experimental sequence. We caution other investigators to be aware of this potential artifact.
The Fish Crow (Corvus Ossifragus) Reaches Nebraska, Joel G. Jorgensen, Melissa J. Panella, W. Ross Silcock, Kristal J. Stoner
The Fish Crow (Corvus Ossifragus) Reaches Nebraska, Joel G. Jorgensen, Melissa J. Panella, W. Ross Silcock, Kristal J. Stoner
Nebraska Bird Review
The Fish Crow (Corvus ossifragus) was formerly endemic to the southeastern United States where it inhabited coastal areas along the Atlantic and Gulf Coasts (McGowan 2001). Since the early 1900s, the species has steadily expanded north and west along major river systems (McGowan 2001). Fish Crow range expansion has followed a logical pattern, expanding along major rivers in regions close to established populations, in adjacent states to the south and east of Nebraska. The species was first recorded in Missouri in 1964 (Robbins and Easterla 1992). In 1984, Fish Crow was first reported in Kansas and by 1991 …
Democracy And The Environment In Latin America, Javier Albert Escamilla
Democracy And The Environment In Latin America, Javier Albert Escamilla
UNLV Theses, Dissertations, Professional Papers, and Capstones
This study examines the ability of democratic and non-democratic states alike to protect the environment. Democracy has long been an important concept in the study of politics and environmental protection is an increasingly important issue in world politics. Advocates of democracy claim democratic states are better able to protect the environment than non-democracies. In contrast there are those that argue democracy's emphasis on individual rights leads to excessive resource consumption. This thesis employs a mixed methods approach to determine if democratic countries protect the environment more than their non-democratic counterparts. In short democracies do protect the environment better than non-democracies …

Empty Ritual: Young-Adult Stepchildren’S Perceptions Of The Remarriage Ceremony, Leslie A. Baxter, Dawn O. Braithwaite, Jody Koenig Kellas, Cassandra Leclair-Underberg, Emily Lamb Normand, Tracy Routsong, Matthew Thatcher
Department of Communication Studies: Faculty Publications
This qualitative study investigated 80 young-adult stepchildren’s talk about one of their parents’ remarriage ceremony. The remarriage event was celebrated in six types of ritual enactments, five of which celebrated the couple’s marriage and one of which was family-centered in its celebration of the beginning of the new stepfamily. Three factors led stepchildren to find the remarriage ceremony empty: (i) a ritual form that was too traditional or not traditional enough; (ii) a ritual enactment that failed to pay homage to either the stepchild’s family of origin or the stepfamily as a unit; and (iii) a ritual enactment that failed …
Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn
Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn
Department of Industrial and Management Systems Engineering: Faculty Publications
Faculty course portfolios are a valuable medium for documenting and making visible the serious intellectual work of teaching. Developing a faculty course portfolio follows the same process one uses to explore a research question. Faculty members inquire, analyze, and document their teaching practices and the resulting student learning and then make the results accessible for use, review, and assessment by one’s peers. In this article, we introduce four types of electronic course portfolios that sponsor different forms of inquiry into student learning. We highlight the major components of each type, offer advice in developing them, and share examples of each. …

The White Dwarfs Within 20 Parsecs Of The Sun: Kinematics And Statistics, Edward M. Sion, Jay B. Holberg, Terry D. Oswalt, George P. Mccook, Richard Wasatonic
Aerospace, Physics, and Space Science Faculty Publications
We present the kinematical properties, distribution of spectroscopic subtypes, and stellar population subcomponents of the white dwarfs within 20 pc of the Sun. We find no convincing evidence of halo white dwarfs in the total 20 pc sample of 129 white dwarfs nor is there convincing evidence of genuine thick disk subcomponent members within 20 parsecs. Virtually, the entire 20 pc sample likely belongs to the thin disk. The total DA to non-DA ratio of the 20 pc sample is 1.6, a manifestation of deepening envelope convection which transforms DA stars with sufficiently thin H surface layers into non-DAs. The …

Psyche + Physique, Janet Winkie
Psyche + Physique, Janet Winkie
Theses
Through this thesis I explore how human perceptions are made regarding masculinity and the impact that apparel and environment have on the male psyche and physique. I perceive the function of men's apparel as providing a hinge, or entry point into the male identity, ultimately examining themes such as gender roles, sexuality, social class and age. In this thesis exploration, I intend to examine the male physique and embody it using male and female byproducts, found objects and accessories.
Incorporating themes such as space and place, this practice of assemblage and installation offers the "staging" of male-themed spaces, providing dialogue …

Determinants Of Alumni Membership In A Dues-Based Alumni Association., Melissa Dawn Newman 1979-
Electronic Theses and Dissertations
Public higher education institutions are presently faced with a perfect storm of financial crises. State appropriations are on the decline, endowments have been substantially reduced as a result of the declining stock market, generally poor economic conditions across the board, and recent, historically high tuition increases make additional tuition hikes an unattractive option for a non-tax based revenue source. As a result of the economic climate within public higher education finance, institutions must increasingly rely on alternative revenue sources, which are largely made up of alumni support. According to Taylor and Massey (1996), "Alumni are a unique, select, and continuing …
Friedrich Schiller's Play : A Theory Of Human Nature In The Context Of The Eighteenth-Century Study Of Life., Susan M. Bentley
Friedrich Schiller's Play : A Theory Of Human Nature In The Context Of The Eighteenth-Century Study Of Life., Susan M. Bentley
Electronic Theses and Dissertations
Friedrich Schiller's psychological theory of play, his hypothesis about human nature, is embedded in the Aesthetic Letters . Its trans-historical value owes much to the committed interest in life in the late Enlightenment, and the theory itself is an example of that period's enthusiastic study of living organisms. It is within this context--of eighteenth-century natural history, natural philosophy and medicine--that the theory can be profitably evaluated. That it is also an example of the connection of the humanities of the time and the emerging life sciences suggests its usefulness as a paradigm today: as a general theory of human nature, …

The Ranking Of Football Teams Using Concepts From The Analytic Hierarchy Process., Yepeng Sun 1976-
Electronic Theses and Dissertations
A new method to rank football teams with the concepts associated with the Analytic Hierarchy Process(AHP) and Graph theory is developed in this thesis. A set of games is interpreted as a graph, in which every vertex represents a team, and every edge represents a team quality comparison evaluated directly from the score difference of a game. A weighted quality comparison value between every two teams is computed from the graph, based on the transitivity relationship of comparison values in the Analytic Hierarchy Process (AHP). All the quality comparison values are input into the software package Expert Choice as the …

Identity And Democracy: Linking Individual And Social Reasoning, John B. Davis, Solange Regina Marin
Identity And Democracy: Linking Individual And Social Reasoning, John B. Davis, Solange Regina Marin
Economics Faculty Research and Publications
Following Amartya Sen's approach, John Davis and Solange Regina Marin look at individual and social reasoning when examining the complex relationship between identity and democracy. They characterize democracy as a process of social or public reasoning that combines the individual reasoning of all citizens. Identity is explained in terms of personal identity, social identity, and individual identity. They argue that democracy in combining the individual reasoning of all citizens responds to individuals’ different personal identity concerns and needs, reflects their shared social identity interests and goals, and accords them rights and responsibilities associated with their many different individual identities.
Why Egregious Errors Of Law May Yet Justify A Refusal Of Enforcement Under The 'New York Convention', Seng Wei, Edward Ti
Why Egregious Errors Of Law May Yet Justify A Refusal Of Enforcement Under The 'New York Convention', Seng Wei, Edward Ti
Research Collection Yong Pung How School Of Law
Parties on the losing side in international arbitration have long argued that an error of law is a defence to the enforcement of foreign awards. Citing article V(2)(b) of the New York Convention, such parties have argued that a manifest error of law is a violation of public policy. While national courts have generally paid little heed to this line of argument, this article seeks to raise the possibility that there may yet be the exceedingly rare instance in which a court should preclude enforcing an award marred by a hideous error of law. Limited review of an arbitrator's application …
