Pastoralist Livestock Marketing Behavior In Northern Kenya And Southern Ethiopia: An Analysis Of Constraints Limiting Off-Take Rates, Christopher B. Barrett, John G. Mcpeak, Winnie Luseno, Peter D. Little, Sharon M. Osterloh, Hussein Mahmoud, Getachu Gebru
Economics - All Scholarship
Pastoralists in East Africa's arid and semi-arid lands (ASAL) regularly confront climatic shocks that plunge them into massive herd die-offs and loss of scarce wealth. One of the most puzzling features of pastoralist behavior in times of stress has been their relatively low and non-responsive rate of marketed off-take of animals when faced with likely losses to herd mortality. As Figure 1, from Desta (1999), finds in 17-year herd history data from Borana pastoralists in southern Ethiopia, mortality always exceeds net sales as a share of beginning period herd size, with the latter never exceeding three percent and moving hardly …

Type I Error Rates For A One Factor Within-Subjects Design With Missing Values, Miguel A. Padilla, James Algina
Type I Error Rates For A One Factor Within-Subjects Design With Missing Values, Miguel A. Padilla, James Algina
Journal of Modern Applied Statistical Methods
Missing data are a common problem in educational research. A promising technique, that can be implemented in SAS PROC MIXED and is therefore widely available, is to use maximum likelihood to estimate model parameters and base hypothesis tests on these estimates. However, it is not clear which test statistic in PROC MIXED performs better with missing data. The performance of the Hotelling- Lawley-McKeon and Kenward-Roger omnibus test statistics on the means for a single factor withinsubject ANOVA are compared. The results indicate that the Kenward-Roger statistic performed better in terms of keeping the Type I error close to the nominal …

A Modification Of The Em Algorithm To Estimate An Andersen-Gill Gamma Frailty Model For Multivariate Failure Time Data, Maria Antònia Barceló, Marc Saez
A Modification Of The Em Algorithm To Estimate An Andersen-Gill Gamma Frailty Model For Multivariate Failure Time Data, Maria Antònia Barceló, Marc Saez
Journal of Modern Applied Statistical Methods
A modification of the Andersen-Gill gamma shared frailty model is presented. The variance of the frailty is directly modeled by means of a generalized linear model, the EM algorithm is modified in order to simultaneously estimate a semiparametric model for the failure times and a model for the variance of the frailty. A simulation study is conducted to evaluate the performance of the proposed algorithm (EMB algorithm) and compared with other methods, a marginal model, and a conditional model. Multivariate data from a nosocomial infection study is used to illustrate the methods. The EMB fit turned out to be better …

Pyruvate Formate Lyase And Acetate Kinase Are Essential For Anaerobic Growth Of Escherichia Coli On Xylose, A. Hansona, Y. Kim, Frank G. Healy, L. O. Ingram, K. T. Shanmugan
Pyruvate Formate Lyase And Acetate Kinase Are Essential For Anaerobic Growth Of Escherichia Coli On Xylose, A. Hansona, Y. Kim, Frank G. Healy, L. O. Ingram, K. T. Shanmugan
Biology Faculty Research
During anaerobic growth of bacteria, organic intermediates of metabolism, such as pyruvate or its derivatives, serve as electron acceptors to maintain the overall redox balance. Under these conditions, the ATP needed for cell growth is derived from substrate-level phosphorylation. In Escherichia coli, conversion of glucose to pyruvate yields 2 net ATPs, while metabolism of a pentose, such as xylose, to pyruvate only yields 0.67 net ATP per xylose due to the need for one (each) ATP for xylose transport and xylulose phosphorylation. During fermentative growth, E. coli produces equimolar amounts of acetate and ethanol from two pyruvates, and these …

Foundations Of Statistical Processing Of Set-Valued Data: Towards Efficient Algorithms, Hung T. Nguyen, Vladik Kreinovich, Gang Xiang
Departmental Technical Reports (CS)
Due to measurement uncertainty, often, instead of the actual values xi of the measured quantities, we only know the intervals [Xi]=[Xi-Di,Xi+Di], where Xi is the measured value and Di is the upper bound on the measurement error (provided, e.g., by the manufacturer of the measuring instrument). These intervals can be viewed as random intervals, i.e., as samples from the interval-valued random variable. In such situations, instead of the exact value of a sample statistic such as covariance C(x,y), we can only have an interval [C](x,y) of possible values of this statistic.
In this paper, we extend the foundations of traditional …

Center for Coastal and Ocean Mapping
High-resolution seafloor mapping often requires optical methods of sensing, to confirm interpretations made from sonar data. Optical digital imagery of seafloor sites can now provide very high resolution and also provides additional cues, such as color information for sediments, biota and divers rock types. During the cruise AT11-7 of the Woods Hole Oceanographic Institution (WHOI) vessel R/V Atlantis (February 2004, East Pacific Rise) visual imagery was acquired from three sources: (1) a digital still down-looking camera mounted on the submersible Alvin, (2) observer-operated 1-and 3-chip video cameras with tilt and pan capabilities mounted on the front of Alvin, and (3) …

Several characteristics of the immunoglobulin (Ig) repertoire in fetuses and adults set them apart from each other. Functionally, this translates into differences in the affinity and effectiveness of the humoral immune response between adults and the very young. At least 2 possibilities could explain these differences: (1) fetal and adult lymphocyte progenitors differ significantly in their potential to form a diverse repertoire, and (2) factors extrinsic to the immunoglobulin locus are more influential to the character of the repertoire. To address this, we used nonobese diabetic-severe combined immunodeficient- β2 microglobulin knockout (NOD/SCID/β2m -/-) mice reconstituted with human B-cell progenitors …

Application Of Genotypic And Phenotypic Analyses To Commercial Probiotic Strain Identity And Relatedness, P. S. M. Yeung, Christopher L. Kitts, Phillip S. Tong, M. E. Sanders
Biological Sciences
Aims: The objective of this study was to generate strain-specific genomic patterns of a bank of 67 commercial and reference probiotic strains, with a focus on probiotic lactobacilli.
Methods and Results: Pulsed-field gel electrophoresis (PFGE) was used as the primary method for strain differentiation. This method was compared with carbohydrate fermentation analysis. To supplement visual comparison, PFGE patterns were analysed quantitatively by cluster analysis using unweighted pair group method with arithmetic averages. SmaI, NotI and XbaI were found to effectively generate clear and easy-to-interpret PFGE patterns of a range of probiotic strains. Some probiotic strains from different sources shared highly …
Sex Differences In Metabolic Rates In Field Crickets And Their Dipteran Parasitoids, Gita R. Kolluru, Mark A. Chappell, Marlene Zuk
Sex Differences In Metabolic Rates In Field Crickets And Their Dipteran Parasitoids, Gita R. Kolluru, Mark A. Chappell, Marlene Zuk
Biological Sciences
Sex differences in metabolic rate (MR) can result from dimorphism in the performance of energetically demanding activities. Male crickets (Teleogryllus oceanicus) engage in costly calling and aggressive activity not performed by females. Consistent with this difference, we found higher maximal MR, factorial scope, and fat content in males than females. T. oceanicus song is also costly because it attracts the parasitoid fly Ormia ochracea. Parasitized crickets had reduced maximal MR consistent with a metabolic cost to harboring larvae. This cost was greater for females, either because females invest more heavily into reproduction at the expense of metabolic …
Alteration Of The Food Web Along The Antarctic Peninsula In Response To A Regional Warming Trend, Mark A. Moline, Herve Claustre, Thomas K. Frazer, Oscar Schofield, Maria Vernet
Alteration Of The Food Web Along The Antarctic Peninsula In Response To A Regional Warming Trend, Mark A. Moline, Herve Claustre, Thomas K. Frazer, Oscar Schofield, Maria Vernet
Biological Sciences
In the nearshore coastal waters along the Antarctic Peninsula, a recurrent shift in phytoplankton community structure, from diatoms to cryptophytes, has been documented. The shift was observed in consecutive years (1991–1996) during the austral summer and was correlated in time and space with glacial melt-water runoff and reduced surface water salinities. Elevated temperatures along the Peninsula will increase the extent of coastal melt-water zones and the seasonal prevalence of cryptophytes. This is significant because a change from diatoms to cryptophytes represents a marked shift in the size distribution of the phytoplankton community, which will, in turn, impact the zooplankton assemblage. …

Interoperability And The Need For Intelligent Software, Jens G. Pohl
Collaborative Agent Design (CAD) Research Center
In my introduction to this year’s conference I will address six questions that I believe come to the core of our conference theme of interoperability. Do we human beings resist change? Is it in fact a human problem and not a technical problem that we are dealing with? Can non-human intelligence exist? Do we even have a need for intelligent software? How did software, particularly intelligent software (i.e., if we accept that there is such a thing) evolve over the past several decades, and what is all this talk about a Semantic Web environment? And, finally, what does the …

Review Of Biological Time, Beth Bojarski
Taproot: A Journal of Outdoor Education
Biological time describes the "natural lifecycles and events of organisms dictated by the presence or absence of light . . . [it is a] unifying theory, linking the timing of ancient calendars with modern scientific research and historical records that show how the natural world is marching to a drumbeat that we are just now learning how to hear."
Between Dancing And Writing: The Practice Of Religious Studies, Kimerer L. Lamothe
Between Dancing And Writing: The Practice Of Religious Studies, Kimerer L. Lamothe
Philosophy & Theory
This book provides philosophical grounds for an emerging area of scholarship: the study of religion and dance.
In the first part, LaMothe investigates why scholars in religious studies have tended to overlook dance, or rhythmic bodily movement, in favor of textual expressions of religious life. In close readings of Descartes, Kant, Schleiermacher, Hegel, and Kierkegaard, LaMothe traces this attitude to formative moments of the field in which philosophers relied upon the practice of writing to mediate between the study of “religion,” on the one hand, and “theology,” on the other.
In the second part, LaMothe revives the work of theologian, …

Children’S Perceptions Of Family Relationships As Assessed In A Doll Story Completion Task: Links To Parenting, Social Competence, And Externalizing Behavior, Deborah Laible, Gustavo Carlo, Julia C. Torquati, Lenna Ontai
Department of Psychology: Faculty Publications
This study was designed to examine the links between parenting, children’s perceptions of family relationships, and children’s social behavior. Seventy-four children (M age = 6.01 years; 39 boys; 35 girls) and their parents took part in the study. Children completed relationship-oriented doll stories that were coded for coherence, prosocial themes, and aggressive themes. Parents completed a report of their child’s social behavior, a parenting scale, and a number of demographic items. Teachers also completed measures of children’s social competence and externalizing behavior. Warm parenting predicted both a child’s representation of prosocial themes in the doll stories and social competence, whereas …

Biotechnology research and innovation depends on the ability to understand the molecular mechanisms of biological processes such as protein–protein and protein–ligand interactions. Surface plasmon resonance (SPR) spectroscopy is now well established as a quantitative technique for monitoring biomolecular interactions. In this study, we examined the recently developed quartz crystal microbalance with dissipation (QCM-D) method as an alternative to SPR spectroscopy to investigate protein–protein interactions, in particular, for chaperone–co-chaperone interactions. In mammalian cells, the Hsp70/Hsp90 organizing protein (Hop) is a co-chaperone required for the association of the molecular chaperones, heat shock protein 70 (Hsp70) and heat shock protein 90 (Hsp90). The …
