Water And Population In The American West, Denise D. Fort Jan 2002

Water And Population In The American West, Denise D. Fort

Faculty Scholarship

The American West is justly famed for its sunshine and wide skies.1 However, there is a potent combination of low rainfall and growing population in the West that ensures that water, or the lack of it, will remain another well-known feature of the region. As the number of people sharing already stressed water supplies increases, the economic, ecological, and social costs of providing water become more evident. Agriculture consumes about 90% of the water that is extracted in the West, and the transfer from agricultural to municipal and industrial uses is invariably complex. Increased water extraction has resulted in the …

Cytokine Regulation In Ra Synovial Tissue: Role Of T Cell/Macrophage Contact-Dependent Interactions., Fionula Brennan, Andrew Foey Jan 2002

Cytokine Regulation In Ra Synovial Tissue: Role Of T Cell/Macrophage Contact-Dependent Interactions., Fionula Brennan, Andrew Foey

School of Biomedical Sciences

Several groups have documented the expression of cytokines in rheumatoid arthritis synovial tissue over the past 15 years or so. These studies have indicated that most cytokines examined are expressed at the mRNA levels at least, and many other cytokines are found in abundance as proteins. Our attention has recently focused on the mechanisms that induce and regulate tumour necrosis factor and IL-10. Other workers and ourselves have found that cell-cell contact is an important signal for the induction of cytokines, and our work has demonstrated that tumour necrosis factor and IL-10 production in rheumatoid arthritis synovial joint cells cultures …

Pair Attribute Learning: Network Construction Using Pair Features, Tony R. Martinez, Eric K. Henderson Jan 2002

Pair Attribute Learning: Network Construction Using Pair Features, Tony R. Martinez, Eric K. Henderson

Faculty Publications

We present the Pair Attribute Learning (PAL) algorithm for the selection of relevant inputs and network topology. Correlations on training instance pairs are used to drive network construction of a single-hidden layer MLP. Results on nine learning problems demonstrate 70% less complexity, on average, without a significant loss of accuracy.

The Algebra And Geometry Of Curve And Surface Inversion, Thomas W. Sederberg, Eng-Wee Chionh, Kent Ridge Jan 2002

The Algebra And Geometry Of Curve And Surface Inversion, Thomas W. Sederberg, Eng-Wee Chionh, Kent Ridge

Faculty Publications

An inversion equation takes the Cartesian coordinates of a point on a parametric curve or surface and returns the parameter value(s) of that point. A 2-D curve inversion equation has the form t = f(x,y)/g(x,y). This paper shows that practical insight into inversion can be obtained by studying the geometry of the implicit curves f(x,y) = 0 and g(x,y) = 0. For example, the relationship between the singular locus of the parametric curve and the lowest possible degree of an inversion equation can be understood in this way. Also, insight is given into what parameter value will be returned if …

The Jewish Community Library In Vienna: From Dispersion And Destruction To Partial Restoration, Richard Hacken Jan 2002

The Jewish Community Library In Vienna: From Dispersion And Destruction To Partial Restoration, Richard Hacken

Faculty Publications

On 25 October 2000, Austria’s first memorial to Jewish victims of the Holocaust was unveiled at the Judenplatz in Vienna. Conceived by Nazi hunter Simon Wiesenthal and designed by British sculptress Rachel Whiteread in the form of a nameless library, a concrete block displays shelves of books with their spines turned to the inside, enclosing an area made inaccessible by a permanently locked door. The outer memorial is designed to represent Jewish culture and learning that were lost forever in the Holocaust, while the empty space within symbolises the many readers of the library who did not live on. Parallel …

Parental Psychological Control: Implications For Childhood Physical And Relational Aggression, David A. Nelson, Nicki R. Crick Jan 2002

Parental Psychological Control: Implications For Childhood Physical And Relational Aggression, David A. Nelson, Nicki R. Crick

Faculty Publications

Children who experience difficulties with peers also tend to experience both concurrent social–psychological difficulties and long-term negative developmental outcomes. Specifically, a significant amount of research has identified peer rejection and isolation as significant precursors to academic troubles and socially deviant behavior (DeRosier, Kupersmidt, & Patterson, 1994; Kupersmidt, Coie, & Dodge, 1990; Parker & Asher, 1987; Parker, Rubin, Price, & DeRosier, 1995). Substantial research and intervention efforts have consequently been dedicated to an understanding of the problem behaviors commonly identified as correlates or antecedents of peer rejection. Childhood aggression is one of the most significant predictors of peer rejection, and has …

Maternal Psychological Control And Preschool Children’S Behavioral Outcomes In China, Russia, And The United States, Susanne Frost Olsen, Chongming Yang, Craig H. Hart, Clyde C. Robinson, Peixia Wu, David A. Nelson, Larry J. Nelson, Shenghua Jin, Jianzhong Wo Jan 2002

Maternal Psychological Control And Preschool Children’S Behavioral Outcomes In China, Russia, And The United States, Susanne Frost Olsen, Chongming Yang, Craig H. Hart, Clyde C. Robinson, Peixia Wu, David A. Nelson, Larry J. Nelson, Shenghua Jin, Jianzhong Wo

Faculty Publications

A growing body of Western literature has demonstrated the importance of three domains of socialization—connection with significant others, regulation of behavior, and the facilitation of psychological autonomy—in predicting outcomes in adolescents and children (Barber, 1997a, 1997b; Gray & Steinberg, 1999; Hart, Newell, & Olsen, in press; Nelson, 1997; Steinberg, Dornbusch, & Brown, 1992). Psychological control—parenting that does not allow children psychological autonomy, as has been defined elsewhere in this volume, has received increased attention in the past decade (for a discussion of definitions and research, see chapter 2, this volume).

Expanding The Study And Understanding Of Psychological Control, Brian K. Barber, Roy A. Bean, Lance D. Erickson Jan 2002

Expanding The Study And Understanding Of Psychological Control, Brian K. Barber, Roy A. Bean, Lance D. Erickson

Faculty Publications

The two central purposes of this volume are to review the historical, conceptual, and empirical literatures on parental psychological control and to advance the rapidly growing scientific literature Ono this aspect of the parent-child relationship. Chapter 2 addressed the first task with a review of published material that has specifically investigated psychological control or variables that are conceptually similar to it. From this review of the historical conceptualizations of parental psychological control, we concluded that psychological control is a psychologically oriented, intrusive, constraining, and manipulating form of parental control in which parents appear to maintain their own psychological status at …

The Influence Of Pitch And Loudness Changes On The Acoustics Of Vocal Tremor, Christopher Dromey, Paul Warrick, Jonathan Irish Jan 2002

The Influence Of Pitch And Loudness Changes On The Acoustics Of Vocal Tremor, Christopher Dromey, Paul Warrick, Jonathan Irish

Faculty Publications

The effect of tremor on phonation is to modulate an otherwise steady sound source in its amplitude, fundamental frequency, or both. The severity of untreated vocal tremor has been reported to change under certain conditions that may be related to muscle tension. In order to better understand the phenomenon of vocal tremor, its acoustic properties were examined as individuals volitionally altered their pitch and loudness. These voice conditions were anticipated to alter the tension of the intrinsic laryngeal muscles. The voices of 10 individuals with a diagnosis of vocal tremor were recorded before participating in a longitudinal treatment study. They …
