Undetected Species Losses, Food Webs, And Ecological Baselines: A Cautionary Tale From The Greater Yellowstone Ecosystem, Usa, Joel Berger
Biological Sciences Faculty Publications
Large protected areas are often considered natural yet outside pressures may compromise ecological integrity. This paper points to a problem in assessing ecological baselines: what if species' extirpations go undetected? I present a data set spanning 130 years that demonstrates the loss of white-tailed jack rabbits Lepus townsendii from two National Parks in the well studied 60,000 km(2) Greater Yellowstone Ecosystem, USA. While these extirpations have been unnoticed until now, an ecological consequence may be elevated predation on juvenile ungulates. A critical challenge we face is how to apply better the concept of shifting baselines to the restoration of functional …
Reproductive Effort In Squirrels: Ecological, Phylogenetic, Allometric, And Latitudinal Patterns, Virginia Hayssen
Reproductive Effort In Squirrels: Ecological, Phylogenetic, Allometric, And Latitudinal Patterns, Virginia Hayssen
Biological Sciences: Faculty Publications
The distinctive features of reproduction in squirrels are the lack of allometric influences on the duration of reproductive investment; the strong allometric influences on offspring mass; and a trade-off between number and size of young, suggesting an important developmental component to reproduction. Lengths of gestation and lactation do not vary with body size but neonatal and weaning mass do. Apparently, the major constraint on reproduction in squirrels is not resources per se (food, calories, minerals, or water) but rather the length of time such resources are available. Squirrels adjust growth rate to fit the timing of resource abundance. Within the …

大體解剖學教學的發展與演變, 榮邦 陳, 琮涵 馮, 銘勳 謝, 啟瑞 曾
Journal of Medical Education
自從Hippocrates以科學的態度開啟了世人對人體構造的了解，多個世紀以來，大體解剖學課程已是醫學教育的核心。近年來由於科技的進步，傳統以大體為基礎的解剖課漸漸地被新的教學工具－模型與動畫所取代，這不僅是一場傳統與新科技的教學方法之爭，亦是醫學教育核心價值之爭。將來的醫學院會採用「先進且多元的技術」取代「讓人學習尊重生命的大體老師」？抑或繼續保留「大體老師」為醫學教育的根源與傳統？本文從解剖學的發展、解剖學課程的演變，以及近年來對解剖學課程提出正反觀點的相關文獻進行整理與探討，提供讀者不同的思維。
The Evolution Of Human Rights Thinking In North Korea, Robert Weatherley, Jiyoung Song
The Evolution Of Human Rights Thinking In North Korea, Robert Weatherley, Jiyoung Song
Research Collection School of Social Sciences
The official discourse of human rights in North Korea has shown signs of evolution in recent times, reflecting a variety of philosophical foundations and a need to respond to mounting criticism from the West. While Confucianism and Marxism have been key in influencing North Korean rights thinking, some of the more recent official pronouncements on rights have a distinctly nationalistic or ‘juche-oriented’ complexion. This shift in emphasis reflects the growing importance of juche to North Korea's state ideology in light of what is perceived as an increasingly hostile international environment that has confronted North Korea since the end of the …

Blastocystis hominis, clasificado como Stramenopile, es el parásito intestinal más frecuente en el hombre. En las heces y cultivos se observan formas con cuerpo central (FCC), granulosas (FGra), globulosas, ameboides, en división binaria y quistes. Su elevada prevalencia, asociación con síntomas en el humano y carencia de tratamiento efectivo, justificó la evaluación del Secnidazol (Unidazol® ZUOZ-PHARMA) en 14 individuos (7 varones y 7 hembras), infectados con B. hominis, con edades entre 5-79 años, quienes fueron evaluados clínica y parasitológicamente antes y después del tratamiento, con una dosis del medicamento: 2g (adultos) y 30 mg/Kg/peso (niños).

Interculturality And The Indigenization Of Modernity: A View From Amazonian Ecuador, Norman E. Whitten Jr
Interculturality And The Indigenization Of Modernity: A View From Amazonian Ecuador, Norman E. Whitten Jr
Tipití: Journal of the Society for the Anthropology of Lowland South America
After introducing the history and topography of the "forest of Canelos," I turn to the central theme of this essay, "the indigenization of modernity." I next illustrate pervasive mythic cosmology to orient the reader to Canelos Quichua Amazonian perspectives on cultural topography. The relationships that obtain in language, history and ecology between the "lowlands" and the 'highlands" address the subject of ethnogenesis in indigenous thought and in written historical portrayal. Bulding toward an indigenous structure of conjuncture, I treat "epistemic distortion" in various academic sectors and attept to counter or deflect what I take to be such distortions. In so …

Cannibals, Amazons, And Social Reproduction In Amazonia, Astrid Steverlynck
Tipití: Journal of the Society for the Anthropology of Lowland South America
This paper analyzes Amerindian representations of Amazon-like women and cannibalism in the context of ideas about the processes of creation. While cannibalism focuses on the socialization of death through male agency and control int he context of relationships with external others, the myths about Amaon-like women focus on the social control of sexuality and female creativity (pregnancy and birth) through the establishment of male-female cooperation. Both discourses rely on the intrinsic qualities of male and female creativity that constitute the elementary structure of Amerindian cosmology. they explore the two most fundamental moments in the chain of creative processes that constitute …

Seismic Reflection Evidence For A Dangerous Grounds Miniplate: No Extrusion Origin For The South China Sea, Peter Clift, Gwang H. Lee, Nguyan Anh Duc, Udo Barckhausen, Hoang Van Long, Sun Zhen
Faculty Publications
The collision of India and Asia has caused large strike-slip faults to form in east Asia, resulting in the "extrusion" of crustal blocks toward the southeast since the Eocene as a result of the indentation of rigid India into Asia. It has been suggested that the South China Sea opened as a result of relative motion between a rigid Indochina (Sundaland) block and China. Alternative models propose that riffing and seafloor spreading were driven by trench forces to the south. We test these competing models by analysis of seismic reflection profiles across the boundary between Sundaland and the southern rifted …

In the summer of 2003, the Littoral Acoustic Demonstration Center conducted an acoustic characterization experiment for a 21-element marine seismic exploration airgun array of total volume of 0.0588 m3 (3590 in.3). Two Environmental Acoustic Recording System buoys, one with a desensitized hydrophone, were deployed at a depth of 758 m in a water depth of 990 m, near Green’s Canyon in the Gulf of Mexico. Shots over a grid were recorded and calibrated to produce absolute broadband (up to 25 kHz) pressure-time dependencies for a wide range of offsets and arrival angles in the water column.

Reproductive Fertility In Herd Bulls, George Perry, Julie Walker, Russ Daly
SDSU Extension Extra Archives
Herd bulls have a large influence on many aspects of beef operations, especially an operation’s profitability. For example, percent calf crop weaned is the single most important factor influencing profitability, and the number of cows bred during the breeding season plays the largest role in percent calf crop weaned. Therefore, an operation’s profitability is directly tied to the herd bull’s breeding ca¬pability. In addition, herd bulls supply half of the genetics to all the calves he sires; therefore, bull selection can be the most powerful method of genetic improvement in the herd. Herd bulls also influence overall herd fertility more …
Disruptive Effects Of Aβ Oligomers To The Radial-Arm Maze Performance Of Rats, Kineta Lynn Morgan-Paisley
Disruptive Effects Of Aβ Oligomers To The Radial-Arm Maze Performance Of Rats, Kineta Lynn Morgan-Paisley
Dissertations
Converging lines of research have implicated a causal relationship between oligomers of amyloid-β and the cognitive impairments associated with Alzheimer's disease (AD); however, very few studies have provided direct experimental evidence of this relationship and none of those studies have used an established model of working memory. The present study used an established model of working memory, the radial-arm maze, to examine the effects of amyloid-β oligomers on the memory of two groups of rats. The experimental group received ICV injections of the culture media (CM) of Chinese Hamster Ovary (CHO) cells transfected with a human mutation of APP containing …

Los cambios en el peso corporal no son buen indicador del estado nutricional de las vacas lecheras. Por ejemplo, mientras que el contenido de las vísceras de una vaca de 1400 lb. pesa aproximadamente 200 lbs., la vaca tiene un consumo diario de cerca de 100 lbs. de alimento (peso fresco) y 160 a 240 lbs. de agua (un galón equivale a 8 lbs). Además, la vaca elimina más de 120 lbs. de estiércol y orina diarios (NRC 2001), así como 50 a 100-o más lbs. de leche. Por tanto, la abilidad de describir de forma precisa los cambios reales …

Two-Dimensional Computer-Generated Ornamentation Using A User-Driven Global Planning Strategy, Dustin Robert Anderson
Master's Theses
Hand drawn ornamentation, such as floral or geometric patterns, is a tedious and time consuming task that requires much skill and training in ornamental design principles and aesthetics. Ornamental drawings both historically and presently play critical roles in all things from art to architecture; however, little work has been done in exploring their algorithmic and interactive generation. The field of computer graphics offers many algorithmic possibilities for assisting an artist in creating two-dimensional ornamental art. When computers handle the repetition and overall structure of ornament, considerable savings in time and money can result. Today, the few existing computer algorithms used …

Through The Glass Darkly: New Paradigms For Counselors, Courage, And Spirituality In Contemporary Education, Judy Goodell, David C. Robinson
Journal of Catholic Education
This article proposes a paradigm shift in the view of the school counselor role. Evolving from the dualistic mind/body split of traditional physics, counseling has largely focused on problem identification and attempting to fix what is wrong. The new sciences of chaos and complexity invite a more holistic view, with the psychospiritual development of all students seen as an appropriate part of a comprehensive education. School counselors are well placed to mentor the psychospiritual development of all students and to facilitate the presence of spirituality on school sites. Two complementary models, Courage to Teach/Lead and the Ignatian model of Spiritual …

Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker
Neuroscience: Faculty Publications
Non-sexual social bonding between adult mammals remains poorly understood, despite its importance in many species. Female meadow voles are territorial and nest alone in long summer day lengths when circulating estradiol concentrations are high, but cohabit in groups in short winter photoperiods when estradiol secretion is low. The influence of day length and estradiol on same-sex huddling behavior was assessed in adult female pairs housed together in long day lengths (LDs) or short day lengths (SDs) from weaning. The behavior of intact, ovariectomized, and estradiol-treated ovariectomized females from each photoperiod was assessed during 3 hour partner preference tests. Intact SD …
A Comparative Analysis Of Pixel-Based And Object-Oriented Image Analysis Methods Using Landsat Imagery, Jason Joseph Delisio
A Comparative Analysis Of Pixel-Based And Object-Oriented Image Analysis Methods Using Landsat Imagery, Jason Joseph Delisio
Masters Theses
Pixel-based and object-oriented image analysis methods are two popular techniques for classifying satellite imagery. Pixel-based analysis is typically used for coarser resolution imagery while object-oriented analysis is ideal for high resolution imagery. However, the ability of object-oriented image analysis to segment images based on factors such as shape, color, texture, and spatial attributes suggest that it can perform as well or better than pixel-based analysis in classifying medium resolution imagery. A comparative analysis of the two methods was performed using Landsat 5 Thematic Mapper imagery from September 2006 to classify grassland quality and land cover in Da'erhanmaoming'an (DaMao) Banner, Inner …

A Theoretical Basis For Learning In Massive Multiplayer Virtual Worlds, Stephen W. Harmon
Journal of Educational Technology Development and Exchange (JETDE)
One of the most compelling affordances of information communications technologies for education is the combination of social interaction, simulation, and creative play offered by online games. Although massive multiplayer online games have been in existence for some time, only with the widespread adoption of highspeed Internet access has their potential has begun to be realized. This article focuses on the affordances of massive multiplayer virtual learning environments (MMVLEs) for education by examining the benefits of a theoretical understanding of learning, and then discussing the concept of affordances. An exploration of the theoretical framework supporting learning in MMVLEs as seen the …

In one of his finest poems, "Asphodel, That Greeny Flower," William Carlos Williams writes: "It is difficult / to get the news from poems / but men die miserably everyday / for lack / of what is found there." Earlier, his contemporary, W.H. Auden, had made his famous claim that "poetry makes nothing happen." While the views of the two great modernists appear to be at odds with each other, they are in fact two sides of the same argument, the yin and yang at the center of all true art. For what these poets saw as critical to both …

Altered glutamate signaling contributes to a myriad of neural disorders, including schizophrenia. While synaptic levels are intensely studied, nonvesicular release mechanisms, including cystine–glutamate exchange, maintain high steady-state glutamate levels in the extrasynaptic space. The existence of extrasynaptic receptors, including metabotropic group II glutamate receptors (mGluR), pose nonvesicular release mechanisms as unrecognized targets capable of contributing to pathological glutamate signaling. We tested the hypothesis that activation of cystine–glutamate antiporters using the cysteine prodrug N-acetylcysteine would blunt psychotomimetic effects in the rodent phencyclidine (PCP) model of schizophrenia. First, we demonstrate that PCP elevates extracellular glutamate in the prefrontal cortex, an effect …
