Predicting Counseling Psychologists' Attitudes And Clinical Judgments With Respect To Older Adults, Jody K. Tomko
Predicting Counseling Psychologists' Attitudes And Clinical Judgments With Respect To Older Adults, Jody K. Tomko
Dissertations
With an emphasis on developmental, strengths-based approaches, as well as a commitment to training multiculturally competent practitioners, the profession of counseling psychology and counseling psychologists are potentially equipped to help address the mental health needs of older adults. Amid projections that Baby Boomers will utilize mental health services at a higher rate than previous cohorts (Rosowsky, 2005), understanding the factors involved in preparing counseling psychologists to provide services to older adults is critical. Older adults, however, have not traditionally been a population served by psychologists (Laganà & Shanks, 2002). Further, possible factors involved in the training and experience of counseling …
Monitoring Calcium, Phosphorous, And Vitamin D₃ Deficiencies In Starter, Growing, And Finishing Pigs, Chris Hostetler, Bob Thaler
Monitoring Calcium, Phosphorous, And Vitamin D₃ Deficiencies In Starter, Growing, And Finishing Pigs, Chris Hostetler, Bob Thaler
SDSU Extension Extra Archives
Due to the increasing cost of dietary ingredients, many swine producers are looking for the most cost-effective ways to meet the nutritional needs of their animals. One of the most costly ingredients in swine diets is inorganic phosphorus, which is normally supple¬mented as dicalcium phosphate. Calcium, phosphorus, and vitamin D3 each play a major role in bone formation, and a deficiency in these nutrients can lead to depressed growth, rickets, broken bones, and, eventually, paralysis in the hind legs. A lesser-known symptom of calcium/phosphorus/vitamin D3 deficiency is the formation of large nodules, called rachitic rosaries, on the ribs of market …
Preventative Feeding Of The Dairy Cow In Transition, Alvaro Garcia, Arnold Hippen
Preventative Feeding Of The Dairy Cow In Transition, Alvaro Garcia, Arnold Hippen
SDSU Extension Extra Archives
The transition period in the lactating dairy cow is characterized by decreased feed intake that starts late in the close-up period and recovers several days after calving. This drop in intake results in an imbalance between required and absorbed nutrients. Other factors that are related to the volume and physical form of the feed can lead to problems frequently observed at calving time. In general, the veterinary diagnosis is based upon clinical symptoms of certain ailments. For greater chances of success and decreased treatment costs, it’s necessary to detect these ailments during their subclinical stage, or, better yet, to prevent …
The Environmental And Economic Benefits Of Highway Access Management: A Multivariate Analysis Using System Dynamics, Dan Andersen
The Environmental And Economic Benefits Of Highway Access Management: A Multivariate Analysis Using System Dynamics, Dan Andersen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Better management of highway operations can be achieved, in part, by controlling vehicular access to adjacent properties and cross streets. This tactic, referred to as access management, has proven safety and operational benefits. However, doubts remain regarding its environmental and economic benefits.
I hypothesize that one environmental indicator, carbon emissions, will decrease with proper access management. Controlling access increases the speed at which vehicles travel, improving fuel efficiency and reducing carbon emissions. My hypothesis relative to financial impacts is that access management will neither help nor harm businesses. Controlling access can reduce travel time which has the effect of increasing …
The Relationship Between High Risk Athletes Risk Perception Of Adventurous Activities, Their Travel Destinations And Their Vacation Travel Patterns, Tanir Magen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Adventure tourism is a growing market segment in the US; the decision to participate in adventurous activities and the selection of risky destinations while on vacation involves ones risk perception about the physical risks that can lead to fatal results from these activities. Existing literature suggest that risk perception is a determinate in choosing a leisure activity and destination while on vacation and that level of tolerance to uncertainty can determine travel behavior (Floyd & Gibson, 2004; Fuchs & Reichel, 2006; Hofstede, 2001; Iso- Ahola, 1980, 1982; Money & Crotts, 2003; Reisinger & Mavondo, 2005). People who have high tolerance …

Students with 504 plans received less frequent follow-up than students in Special Education. Results indicated that schools were generally following federal guidelines and recommendations …
Lessons In Humanity: A Memoir, Chelsi Joy Sutton-Linderman
Lessons In Humanity: A Memoir, Chelsi Joy Sutton-Linderman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the opening pages of his work, Dog Years; A Memoir, Mark Doty explains: Love for a wordless creature, once it takes hold, is an enchantment, and the enchanted speak, famously, in private mutterings, cryptic riddles, or gibberish. This is why I shouldn't be writing anything about the two dogs that have been such presences for sixteen years of my life. How on earth could I stand at the requisite distance to say anything that might matter? (1)
In this thesis I argue that Doty, among other respected contemporary writers, is saying something that matters when he writes of …

Participants completed an online pretest survey and then viewed the "Face the Fats" website at their own pace. …
Evolutionary Genetics Of Tetrodotoxin (Ttx) Resistance In Snakes: Tracking A Feeding Adaptation From Populations Through Clades, Chris R. Feldman
Evolutionary Genetics Of Tetrodotoxin (Ttx) Resistance In Snakes: Tracking A Feeding Adaptation From Populations Through Clades, Chris R. Feldman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Understanding the nature of adaptive evolution has been the recent focus of research detailing the genetic basis of adaptation and theoretical work describing the mechanics of adaptive evolution. Nevertheless, key questions regarding the process of adaptive evolution remain. Ultimately, a detailed description of the ecological context, evolutionary history, and genetic basis of adaptations is required to advance our understanding of adaptive evolution. To address some of the contemporary issues surrounding adaptive evolution, I examine phenotypic and genotypic changes in a snake feeding adaptation.
Adaptations can arise through fixation of novel mutations or recruitment of existing variation. Some populations of the …

Treatment Of Saltcedar (Tamarix Spp.): Economics And Feasibility, Christopher L. Thompson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The invasive species Saltcedar is affecting water and land resources throughout the western states of America. Because of great water use capabilities and other ecosystem detriments, Saltcedar has been targeted for treatment.
For successful management of Saltcedar, individual landowners need to be aware of the costs and benefits of treating Saltcedar. Eleven of the most commonly reported treatment methods were evaluated for firm level economic feasibility. Evaluated on the basis of treatment cost, treatment effectiveness, Saltcedar water-use, and re-vegetation water-use, a production plan of ten years was created for each treatment method. Some treatment methods required re-treatment and were evaluated …

Self-Medicative Behavior Of Sheep Experiencing Gastrointestinal Nematode Infections And The Postingestive Effects Of Tannin, Larry D. Lisonbee
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Diet selection and self-medication are fundamental to the survival of all species. The abilities to choose healthy foods in response to past consequences are basic elements of evolution. This study explores self-medication regarding tannins both as a medication and as a dietary challenge. In the first study, sheep with natural parasite infections were offered a low quality supplement containing a dose of tannins considered to be therapeutic (medicine), while the control infected lambs received the same supplement without tannins (placebo). This study included a group of parasite-free lambs. The parasitized lambs ate more of the tannin containing supplement than non-parasitized …

Agroforestry Practice Adoption Among Solomon Island Women On The Island Of Malaita, Etta K. Sechrest
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The goal of agricultural training is the adoption and diffusion of introduced agriculture techniques. New subsistence agricultural techniques have been introduced mainly to the male population in many developing countries, even though most subsistence farmers are women. Therefore, an understanding of how new subsistence agricultural techniques can be introduced and adopted by women would be important to achieve. This study focuses on women's adoption of agricultural techniques. It takes place on the island of Malaita, in the Solomon Islands. The study looks at the adoption of agroforestry and several other subsistence techniques that were introduced under a joint program by …
A Conceptual Framework For Understanding Effects Of Wildlife Water Developments In The Western United States, Randy T. Larsen
A Conceptual Framework For Understanding Effects Of Wildlife Water Developments In The Western United States, Randy T. Larsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Free water can be a limiting factor to wildlife in arid regions of the world. In the western United States, management agencies have installed numerous, expensive wildlife water developments (e.g. catchments, guzzlers, wells) to: 1) increase the distribution or density of target species, 2) influence animal movements, and 3) mitigate for the loss of available free water. Despite over 50 years as an active management practice, water developments have become controversial for several species. We lack an integrated understanding of the ways free water influences animal populations. In particular, we have not meshed understanding of evolutionary adaptations that reduce the …
Synthetic Complexes Of Relevance To Ni(Ii)-Containing Enzymes, Katarzyna Rudzka
Synthetic Complexes Of Relevance To Ni(Ii)-Containing Enzymes, Katarzyna Rudzka
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The work outlined herein presents an investigation of synthetic model complexes of relevance to the active sites of Ni(II)-containing enzymes, particularly urease, glyoxalase I, and acireductone dioxygenase. The research focuses on studying the structural and reactivity features of nickel complexes with biologically relevant substrates. The anion of acetohydroxamic acid is a well-known inhibitor of urease enzymes, including those isolated from Klebsiella aerogenes and Bacillus pasteurii. A precursor to the acetohydroxamate coordination in ureases is proposed to be an interaction between Ni(II) and acetohydroxamic acid. By using a novel supporting chelate ligand capable of secondary hydrogen bonding interactions a novel …

Aminoglycosides And Syringomycin E As Fungicides Against Fusarium Graminearum In Head Blight Disease, Yukie Kawasaki
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Fusarium graminearum is one of the most problematic phytopathogens in US agriculture. This fungus causes head blight, foot rot, and damping off on wheat and barley. The infection lowers the grain yield and causes contamination of the grain product with mycotoxins. Effective control measures are lacking, and new fungicides that kill F. graminearum but remain safe and economical to use are needed. Newly synthesized aminoglycosides (JL22, JL38, JL39, JL40, NEOF004, NEOF005), classic aminoglycosides (amikacin, gentamicin, kanamycin A, kanamycin B, neomycin, and ribostamycin), and a lipopeptide, syringomycin E (SRE), were studied to determine their antifungal potential to control F. graminearum. …
Essays On Investment Fluctuation And Market Volatility, Chaoqun Lai
Essays On Investment Fluctuation And Market Volatility, Chaoqun Lai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This dissertation includes two different groups of objects in macroeconomics and financial economics. In macroeconomics, the aggregate investment fluctuation and its relation to an individual firm's behavior have been extensively studied for the past three decades. Most studies on the interdependence behavior of firms' investment focus on the key issue of separating a firm's reaction to others' behavior from reaction to common shocks. However, few researchers have addressed the issue of isolating this endogenous effect from a statistical and econometrical approach. The first essay starts with a comprehensive review of the investment fluctuation and firms' interdependence behavior, followed by an …

Student Achievement And Affective Traits In Electrical Engineering Laboratories Using Traditional And Computer-Based Instrumentation, Matthew D. Lammi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Distance education has the ability to transcend distance and time, reaching students anywhere at any time, particularly those underrepresented in engineering. Engineering is a practice-oriented profession requiring an interweaving of scientific theory and applied hands-on activities. Despite the need for distance education in engineering, few studies have systematically investigated the impact of student achievement and attitude in distance engineering laboratories. This quasi-experimental research addressed that need by studying the cognitive and affective domains of achievement in engineering laboratories while employing computer-based and traditional oscilloscopes. The students from two courses, electrical engineering for nonmajors and electronic fundamentals, were randomly assigned into …

Macroalgae And Eelgrass Mapping In Great Bay Estuary Using Aisa Hyperspectral Imagery, Shachak Pe'eri, J. Ru Morrison, Frederick T. Short, Arthur C. Mathieson, Anna Brook, Philip Trowbridge
PREP Reports & Publications
Increase in nitrogen concentration and declining eelgrass beds in Great Bay Estuary have been observed in the last decades. These two parameters are clear indicators of the impending problems for NH’s estuaries. The NH Department of Environmental Services (DES) in collaboration with the New Hampshire Estuaries Project (NHEP) adopted the assumption that eelgrass survival can be used as the water quality target for nutrient criteria development for NH’s estuaries. One of the hypotheses put forward regarding eelgrass decline is that a possible eutrophication response to nutrient increases in the Great Bay Estuary has been the proliferation of nuisance macroalgae, which …
