The Impact Of Species Concept On Biodiversity Studies, Keith A. Crandall, Paul-Michael Agapow, Olaf R. P. Bininda-Emonds, John L. Gittleman, Georgina M. Mace, Jonathon C. Marshall, Andy Purvis

Faculty Publications

Species are defined using a variety of different operational techniques. While discussion of the various methodologies has previously been restricted mostly to taxonomists, the demarcation of species is also crucial for conservation biology. Unfortunately, different methods of diagnosing species can arrive at different entities. Most prominently, it is widely thought that use of a phylogenetic species concept may lead to recognition of a far greater number of much less inclusive units. As a result, studies of the same group of organisms can produce not only different species identities but also different species range and number of individuals. To assess the …

Ascertaining The Importance Of Neurons To Develop Better Brain-Machine Interfaces, Justin C. Sanchez, Jose M. Carmena, Mikhail A. Lebedev, Miguel A.L. Nicolelis, John G. Harris, Jose C. Principe

Electrical and Computer Engineering Faculty Research & Creative Works

In the design of brain-machine interface (BMI) algorithms, the activity of hundreds of chronically recorded neurons is used to reconstruct a variety of kinematic variables. A significant problem introduced with the use of neural ensemble inputs for model building is the explosion in the number of free parameters. Large models not only affect model generalization but also put a computational burden on computing an optimal solution especially when the goal is to implement the BMI in low-power, portable hardware. In this paper, three methods are presented to quantitatively rate the importance of neurons in neural to motor mapping, using single …

Evolution Of Morphological Integration. I. Functional Units Channel Stress-Induced Variation In Shrew Mandibles, Alexander V. Badyaev, Kerry R. Foresman

Biological Sciences Faculty Publications

Stress-induced deviations from normal development are often assumed to be random, yet their accumulation and expression can be influenced by patterns of morphological integration within an organism. We studied within-individual developmental variation ( fluctuating asymmetry) in the mandible of four shrew species raised under normal and extreme environments. Patterns of among-individual variation and fluctuating asymmetry were strongly concordant in traits that were involved in the attachment of the same muscles (i.e., functionally integrated traits), and fluctuating asymmetry was closely integrated among these traits, implying direct developmental interactions among traits involved in the same function. Stress-induced variation was largely confined to …

Prediction Of Growth Factor Effects On Engineered Cartilage Composition Using Deterministic And Stochastic Modeling, Sean S. Kohles, Asit K. Saha, J. (Jagannath) Mazumdar

Mechanical and Materials Engineering Faculty Publications and Presentations

In the design of engineered tissues, guided balance of biomaterial degeneration with tissue synthesis offers refined control of construct development. The objective of this study was to develop a mathematical model that describes the steady state metabolism of extracellular matrix molecules (ECM: glycosaminoglycan and collagen) in an engineered cartilage construct taking into account localized environmental changes that may arise because of the application of growth factors. The variable effects of growth factors were incorporated in the form of random noise rather than the difference in rates of synthesis and catabolism. Thus, the frequency of ECM accumulation for each matrix molecule …

The Social Construction Of Rape Research: Exploring Epistemologies And Evaluating Methods, Edith M. Fisher

Dissertations

The most widely known national study of rape found that one in four college-age women has been the victim of rape or attempted rape. Conservative writers have criticized that study for overestimating the possible prevalence of rape in the U.S. My research uses more sensitive instruments and administration techniques, seeking to estimate the prevalence of rape in the lives of women at a large midwestern public university. I address questions about the validity of previous rape research and compare methods of collecting sexual violence information by questionnaire (322 mailed surveys and 300 interviewer-administered surveys). Additional interviews with 62 of the …

The Interactions Between An Orthodox Christian Worldview And Environmental Attitudes And Beliefs; For The Purpose Of Developing Better Instructional Practice In Support Of Environmental/Ecological Attitudes And Knowledge, Robert S. Keys

Dissertations

Students bring with them to the classroom a wide variety of beliefs and attitudes about the environment and its associated issues. One worldview belief structure prominently discussed in ecological discussions is the worldview of orthodox Christianity. This study uses both quantitative and qualitative measures to analyze the degree to which the orthodox Christian worldview of students influences their environmental attitudes and beliefs. Surveys were conducted with 281 undergraduate pre-service elementary teaching students enrolled in a science methods course to determine the degree to which orthodox Christian worldviews and ecological worldviews interact with one another. From this pool of students, 16 …

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. …

Child Welfare And Devolving Federalism: An Analysis Of The Effects Of Federal Funding Schemes On Selected Child Welfare Outcomes In Michigan, Timothy J. Kangas

Dissertations

Child abuse and neglect has become a pervasive problem across the United States. Between 1985 and 1995 the foster care population in the United States grew by 79%, with costs soaring into the billions. During the mid-1990s, in an effort to address this issue, the federal government shifted from using a funding scheme identified with a traditional model of federalism to one identified with devolving federalism. In Michigan, the focus of this research, this shift in approaches occurred through the issuance of block grant funding for child welfare programming. The intent of this shift was to decentralize elements of 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, …

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.
