Uso De Subproductos En Las Dietas De Crecimiento De Becerras Lecheras, K. F. Kalscheur, A. D. Garcia

SDSU Extension Extra Archives

Los objetivos de un programa de alimentación de becerras lecheras son alcanzar un determinado peso al parto a los 24 meses de edad o menos, mejorar la eficiencia alimenticia y reducir los costos y lograr ambos al tiempo que se permite que el animal exprese su máximo potencial genético para la producción lechera. Los costos de alimentación siguen siendo los mayores en la crianza de las becerras; por lo tanto, una reducción en los costos del alimento que no sacrifica la producción mejora el ingreso neto. Los costos de alimentación pueden reducirse por medio del uso de subproductos disponibles localmente. …

On Similarity Measures For Cluster Analysis, Ahmed Najeeb Khalaf Albatineh

Dissertations

This study discusses the relationship between measures of similarity which quantify the agreement between two clusterings of the same set of data. This study identifies a family [Special characters omitted.] of similarity measures which are of a special form and attain a maximum value of 1 and becomes identical when corrected for chance agreement. In particular, this study proves that the similarity measures of Rand (R), Hubert (H), and Czekanowski (CZ) are identical when corrected for chance agreement. It also proves that the measures of McConnaughey (MC) and Kulczynski (K) are identical when corrected for chance agreement. Moreover, if the …

Perspectival Anthropology And The Method Of Controlled Equivocation, Eduardo Viveiros De Castro

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article argues that doing anthropology means comparing anthropologies. Comparison is not just our primary analytic tool, it is also our raw material and our ultimate grounding, since what we compare are always and necessarily, in one form or other, comparisons. If, as Marilyn Strathern suggests, culture consists in the way people draw analogies between different domains of their worlds, then every culture is a multidimensional process of comparison. Likewise, if anthropology studies culture through culture, then, following Roy Wagner, whatever operations characterize our investigations must also be general properties of culture. Intracultural relations, or internal comparisons, and intercultural relations, …

The sample consisted of 20 students in 9th and 12th grades attending a school of choice. Respondents were interviewed using a structured interview protocol.

The National Council for Research on Women study (Thom, 2001) found that girls are more successful in math and science programs that incorporate acooperative, hands-on approach than in programs that stress competition and individual learning. This finding was supported by this study among 20 high school girls in a school whose mission is …

School Counselors’ Perceptions Of Developmental Guidance: A Qualitative Study, Lori A. Pashnik

Dissertations

A developmental emphasis is the fundamental core of the school counseling profession. However, Comprehensive Guidance and Counseling Programs (CG&CPs) that have been identified as developmental have been shown to have significant gaps with regard to developmental theoretical concepts. In addition, counselors who are implementing CG&CPs are unsure of how to put developmental principles into practice. This study explored how elementary and middle school counselors who currently implement CG&CPs perceive the developmental philosophical foundation of the program. A focus group methodology was used for this study to gain an in-depth understanding of elementary and middle school counselors’ perceptions of developmental guidance. …

Monitoring The Effects Of Psychotropic Drugs In Students With Emotional Impairments: Home And School Data, Lynne E. Turner

Dissertations

Research has shown that schools do not typically participate in the systematic monitoring of psychotropic medications prescribed to school-aged children with emotional disorders. Conversely, research indicates that the information that is relayed to the prescribing physician from the schools consists, in general, of informal global reports regarding the student's overall behavior. Additionally, research evaluating systematic monitoring systems within schools has lacked input from the prescribing physician regarding relevant data to be collected. These findings provided impetus for the present project, which was an attempt to develop a practical system for schools to monitor possible desired and adverse effects of psychotropic …

Homing Endonucleases Encoded By Germ Line-Limited Genes In Tetrahymena Thermophila Have Apetela2 Dna Binding Domains, Jeffrey D. Wuitschick, Paul R. Lindstrom, Alison E. Meyer, Kathleen M. Karrer

Biological Sciences Faculty Research and Publications

Three insertion elements were previously found in a family of germ line-limited mobile elements, the Tlr elements, in the ciliate Tetrahymena. Each of the insertions contains an open reading frame (ORF). Sequence analysis of the deduced proteins encoded by the elements suggests that they are homing endonucleases. The genes are designated TIE1-1, TIE2-1, and TIE3-1 for Tetrahymena insertion-homing endonuclease. The endonuclease motif occupies the amino terminal half of each TIE protein. The C-terminal regions of the proteins are similar to the APETELA2 DNA binding domain of plant transcription factors. The TIE1 and TIE3 elements belong to families of repeated sequences …

A New Species Of Callulina (Anura: Microhylidae) From The West Usambara Mountains, Tanzania, Rafael O. De Sá, Simon P. Loader, Alan Channing

Biology Faculty Publications

The description of the species Callulina kreffti was based on specimens collected in the East Usambara Mountains of Tanzania. Successive collecting has shown this species to be widely distributed through the Eastern Arc Mountains. Advertisement calls from populations in the type locality of Callulina kreffti were compared with calls from populations in the West Usambara Mountains. Analysis of the calls suggested that these two populations of Callulina represent two separate taxa. Subsequent morphological and molecular investigations indicated that these two populations are distinct. Herein, we describe a new Callulina species on the basis of call, morphology and molecular sequences.

Environmental Education And Metaethics, Owen Goldin

Philosophy Faculty Research and Publications

Contrā Dale Jamieson, the study of the metaethical foundations of environmental ethics may well lead students to a more environmentally responsible way of life. For although metaethics is rarely decisive in decision making and action, there are two kinds of circumstances in which it can play a crucial role in our practical decisions. First, decisions that have unusual features do not summon habitual ethical reactions, and hence invite the application of ethical precepts that the study of metaethics and ethical theory isolate and clarify. Second, there are times in which the good of others (including organisms and systems in the …

Interferometric And Holographic Imaging Of Surface-Breaking Cracks, James Lawrence Blackshire, Bradley D. Duncan

Electro-Optics and Photonics Faculty Publications

Two advanced nondestructive evaluation systems are developed for imaging surface-breaking cracks in aerospace materials. The systems use scanning heterodyne interferometry and frequency-translated holography principles to image ultrasonic displacement fields on material surfaces with high resolution and sensitivity. Surface-breaking cracks are detected and characterized by visualizing near-field ultrasonic scattering processes, which in turn results in local intensification of ultrasonic displacement fields in the immediate vicinity of a crack. The local intensification permits cracks to be easily distinguished from background levels, and creates unique displacement field images that follow the contours and morphology of the cracks with microscopic precision. The interferometric and …

Familial And Psychosocial Factors Affecting Adolescents' Academic Achievement, Isa Abdulnasir Ribadu

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the influence of family cohesion, family adaptability, self-image, and locus-of-control on two measures of academic achievement among male and female adolescents. Using a self-administered questionnaire, data were gathered from a convenient sample of 230 students from five high schools in San Bernardino County in southern California. The survey included the Offer Self-image Questionnaire, Family Adaptability and Cohesion Evaluation Scale III, the Nowick-Strickland Locus-of-Control Scale, academic achievement measures, and demographic measures that assessed individual and family characteristics. Family cohesion, family adaptability, self-image, and locus-of-control were significant predictors of both measures of academic achievement. Also, family cohesion and family …

The Association Of Blood Type On The Five Factors Of Personality In Chinese Adolescents, Kunher Wu

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to identify the number of personality factors in Chinese adolescents using the Chinese Revised NEO Personality Inventory (NEO-PI-R) and to determine whether blood type is associated with personality. It is widely accepted by psychologists that the five-factor model can provide an adequate representation of adult personality dimensions, but there is less agreement on the number of factors observable in adolescence. A total of 3,396 11^th graders from the city of Kaohsiung, Taiwan completed the Chinese NEO-PI-R. Principle component analysis with varimax rotation showed five factors of personality in these Taiwanese adolescents, which clearly …

Regulatory Mechanisms Of Uterine Artery Contractility : Effect Of Pregnancy, Daliao Xiao

Loma Linda University Electronic Theses, Dissertations & Projects

Regulation of uterine blood flow during pregnancy is important not only for the growth and survival of the fetus but also for cardiovascular well-being of the mother. Pregnancy is associated with a significant decrease in uterine artery vascular tone and a dramatic increase in uterine blood flow. Previous studies have been focused on adaptation of the endothelium to pregnancy and indicated that increased NO sythesis/release plays an important role in vasodilation of the uterine artery in pregnancy. However, little is known about the adaptation of contractile mechanisms of the uterine artery to pregnancy. The central hypothesis of the proposed studies …

Regulation Of Ca2+-Activated K+ Channel: Changes With Development, Mike T. Lin

Loma Linda University Electronic Theses, Dissertations & Projects

In ovine middle cerebral arteries, it has been shown that the [Ca²⁺]_i change in response to iberiotoxin, a selective BK channel blocker, is significantly different between adult and fetal VSMCs. Our study of basilar VSMCs in whole-cell preparations showed that the total outward current density of fetal myocytes (57.9 ± 6.7 pA/pF) was greater than that of the adult (37.9 ±1.8 pA/pF). This increase in outward current density is contributed by an increase in BK channel current density in fetal myocytes. Excised, inside-out preparations showed that the unitary conductance, as well as the BK channel expression, did …

Mechanisms Of Oxidative Stress Resistance In Porphyromonas Gingivalis W83, Neal Antonio Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

Porphyromonas gingivalisis one of the most important bacterial etiological agents involved in adult periodontitis. It possesses several virulence factors which aid in its persistence in the periodontal pocket leading to the development of some systemic illnesses. As an anaerobe, P. gingivalismust employ mechanisms to avoid oxidative stress generated by reactive oxygen species during phagocytosis, or the occasional exposure to air. Presently, only three proteins with antioxidant enzymatic function have been identified as playing a role in oxidative stress resistance in P. gingivalis. In this study, attention was focused on the alkyl hydroperoxidase subunit C (ahpC)and bacterioferritin comigratory …

Development Of Web Tools For Nlx Simulation Software, Daniel Chai Siriphongs

Loma Linda University Electronic Theses, Dissertations & Projects

Valuable mathematical equations have developed within biology and other sciences (physics, chemistry, etc.) that model various processes, but the complexity of the equations are not easily understood by students, scientists, and those with limited knowledge of the subject area. Simulation software used to visually explain a model is normally proprietary to the specific model equations and cannot be easily adapted to new models by non-programmers. Simulation software needs to be modular and based upon web technologies so that the software can be run on multiple platforms. The NLX simulation software is a group of Java-based objects that can be combined …

Functional Status In Children Diagnosed With All: Age And Gender Effects, Sean Eugene Evans

Loma Linda University Electronic Theses, Dissertations & Projects

Age and gender have been purported as important variables in predicting the outcome of children diagnosed with leukemia. This study examines the relationship between age and gender as predictors of functional status in children following the completion of the induction phase of their treatment (i.e., approximately 5-weeks following their diagnosis) for acute lymphocytic leukemia (ALL). Prior to analyses, it was asserted that boys and girls would indicate unique experiences of perceived pain intensity and would yield significant differences in functional status scores as measured by the children’s parents. A sample of 50 boys (N=33) and girls (N=17) between the ages …

Diet Composition Of Coyotes In The Cuyahoga Valley National Park, Ohio, Jonathon D. Cepek

United States Department of Agriculture Wildlife Services: Staff Publications

The diet and food habits of coyotes (Canis latrans) in Ohio's Cuyahoga Valley National Park (CVNP) were examined by analyzing 50 scat samples collected during coyote population surveys between February 199*-March 1999. The Cuyahoga Valley National Park, a 13,770-hectare public-use park surrounded by residential communities, is located between Cleveland and Akron, Ohio. The park had over 3 million visitors in 1999, and is suffering from the pressures of increased urbanization in surrounding areas. Coyotes were first documented in the CVNP during the 1980s, and since then public interactions with coyotes have increased. The coyote is the top predator …

Diploid And Polyploid Cytotype Distribution In Melampodium Cinereum And M. Leucanthum (Asteraceae, Heliantheae), Tod F. Stuessy, Hanna Weiss-Schneeweiss, David J. Keil
