Admixture Patterns And Genetic Differentiation In Negrito Groups From West Malaysia Estimated From Genome-Wide Snp Data, Timothy A. Jinam, Maude E. Phipps, Naruya Saitou, The Hugo Pan-Asian Snp Consortium

Human Biology

Southeast Asia houses various culturally and linguistically diverse ethnic groups. In Malaysia, where the Malay, Chinese, and Indian ethnic groups form the majority, there exist minority groups such as the "negritos" who are believed to be descendants of the earliest settlers of Southeast Asia. Here we report patterns of genetic substructure and admixture in two Malaysian negrito populations (Jehai and Kensiu), using ~50,000 genome-wide single-nucleotide polymorphism (SNP) data. We found traces of recent admixture in both the negrito populations, particularly in the Jehai, with the Malay through principal component analysis and STRUCTURE analysis software, which suggested that the admixture was …

The Andaman Islanders In A Regional Genetic Context: Reexamining The Evidence For An Early Peopling Of The Archipelago From South Asia, Gyaneshwer Chaubey, Phillip Endicott

Human Biology

The indigenous inhabitants of the Andaman Islands were considered by many early anthropologists to be pristine examples of a "negrito" substrate of humanity that existed throughout Southeast Asia. Despite over 150 years of research and study, questions over the extent of shared ancestry between Andaman Islanders and other small-bodied, gracile, dark-skinned populations throughout the region are still unresolved. This shared phenotype could be a product of shared history, evolutionary convergence, or a mixture of both. Recent population genetic studies have tended to emphasize long-term physical isolation of the Andaman Islanders and an affinity to ancestral populations of South Asia. We …

Craniodental Affinities Of Southeast Asia's "Negritos" And The Concordance With Their Genetic Affinities, David Bulbeck

Human Biology

Genetic research into Southeast Asia's "negritos" has revealed their deep-rooted ancestry, with time depth comparable to that of Southwest Pacific populations. This finding is often interpreted as evidence that negritos, in contrast to other Southeast Asians, can trace much of their ancestry directly back to the early dispersal of Homo sapiens in the order of 70 kya from Africa to Pleistocene New Guinea and Australia. One view on negritos is to lump them and Southwest Pacific peoples into an "Australoid" race whose geographic distribution had included Southeast Asia prior to the Neolithic incursion of "Mongoloid" farmers. Studies into Semang osteology …

Stress And Reproductive Hormones In Grizzly Bears Reflect Nutritional Benefits And Social Consequences Of A Salmon Foraging Niche, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits

Physiology Collection

Physiological indicators of social and nutritional stress can provide insight into the responses of species to changes in food availability. In coastal British Columbia, Canada, grizzly bears evolved with spawning salmon as an abundant but spatially and temporally constrained food source. Recent and dramatic declines in salmon might have negative consequences on bear health and ultimately fitness. To examine broadly the chronic endocrine effects of a salmon niche, we compared cortisol, progesterone, and testosterone levels in hair from salmon-eating bears from coastal BC (n = 75) with the levels in a reference population from interior BC lacking access to salmon …

Laterality Influences Schooling Position In Rainbowfish, Melanotaenia Spp, Anne-Laurence Bibost, Culum Brown

Aquaculture Collection

Cerebral lateralization is a widespread trait among animals, is often manifested as side biases in behaviour (laterality) and has been suggested to provide fitness benefits. Here we examined the influence of laterality on the organisation of fish schools using rainbowfish (Melanotaenia spp) as model species. The pattern and strength of laterality for each individual was determined by examining eye preferences whilst examining their reflection in a mirror. Schools of four fish of known laterality were then created and the preferred position for each fish within the school was repeatedly observed in a flume. Fish which showed right eye preferences in …

Socially Excluded Individuals Fail To Recruit Medial Prefrontal Cortex For Negative Social Scenes, Katherine E. Powers, Dylan D. Wagner, Catherine J. Norris, Todd F. Heatherton

Dartmouth Scholarship

Converging behavioral evidence suggests that people respond to experiences of social exclusion with both defensive and affiliative strategies, allowing them to avoid further distress while also encouraging re-establishment of positive social connections. However, there are unresolved questions regarding the cognitive mechanisms underlying people's responses to social exclusion. Here, we sought to gain insight into these behavioral tendencies by using functional magnetic resonance imaging (fMRI) to examine the impact of social exclusion on neural responses to visual scenes that varied on dimensions of sociality and emotional valence. Compared to socially included participants, socially excluded participants failed to recruit dorsomedial prefrontal cortex …

Communication And Common Interest, Peter Godfrey-Smith, Manolo Martínez

Publications and Research

Explaining the maintenance of communicative behavior in the face of incentives to deceive, conceal information, or exaggerate is an important problem in behavioral biology. When the interests of agents diverge, some form of signal cost is often seen as essential to maintaining honesty. Here, novel computational methods are used to investigate the role of common interest between the sender and receiver of messages in maintaining cost-free informative signaling in a signaling game. Two measures of common interest are defined. These quantify the divergence between sender and receiver in their preference orderings over acts the receiver might perform in each state …

Confronting Uncertainty In Wildlife Management: Performance Of Grizzly Bear Management, Kyle A. Artelle, Sean C. Anderson, Andrew B. Cooper, Paul C. Paquet, John D. Reynolds, Chris T. Darimont

Wildlife Population Management Collection

Scientific management of wildlife requires confronting the complexities of natural and social systems. Uncertainty poses a central problem. Whereas the importance of considering uncertainty has been widely discussed, studies of the effects of unaddressed uncertainty on real management systems have been rare. We examined the effects of outcome uncertainty and components of biological uncertainty on hunt management performance, illustrated with grizzly bears (Ursus arctos horribilis) in British Columbia, Canada. We found that both forms of uncertainty can have serious impacts on management performance. Outcome uncertainty alone – discrepancy between expected and realized mortality levels – led to excess mortality in …

Food Sovereignty: An Alternative Paradigm For Poverty Reduction And Biodiversity Conservation In Latin America, M. Jahi Chappell, Hannah Wittman, Christopher M. Bacon, Bruce G. Ferguson, Luis Garcia Barrios, Raúl Garcia Barrios, Daniel Jaffee, Jefferson Lima, V. Ernesto Méndez, Helda Morales, Lorena Soto-Pinto, John Vandermeer, Ivette Perfecto

Sociology Faculty Publications and Presentations

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …

Metergoline, The Basolateral Amygdala And The Ventral Pallidum: Implications For Panic Disorder, Douglas Ryan Schuweiler

Theses and Dissertations

Panic disorder (PD) is a common mental illness characterized by recurring spontaneous panic attacks. Scientific investigation into PD has been accelerated by the development of rat models of PD. These models can be validated by responses to intravenous sodium lactate (NaLac), including tachycardia, that are similar to PD patient responses. Previous work on established PD models has suggested that antagonism of serotonin (5-HT) receptors in the basolateral amygdala (BLA) may be sufficient to model PD. To test this hypothesis metergoline (MET), a 5-HT receptor antagonist, or vehicle was microinjected into the BLA of anesthetized rats. Following the microinjection, NaLac or …

Automatic Domain Identification For Linked Open Data, Sarasi Lalithsena, Pascal Hitzler, Amit P. Sheth, Prateek Jain

Kno.e.sis Publications

Linked Open Data (LOD) has emerged as one of the largest collections of interlinked structured datasets on the Web. Although the adoption of such datasets for applications is increasing, identifying relevant datasets for a specific task or topic is still challenging. As an initial step to make such identification easier, we provide an approach to automatically identify the topic domains of given datasets. Our method utilizes existing knowledge sources, more specifically Freebase, and we present an evaluation which validates the topic domains we can identify with our system. Furthermore, we evaluate the effectiveness of identified topic domains for the purpose …

An Analysis Of The Use Of Dogs In Predicting Human Toxicology And Drug Safety, Jarrod Bailey, Michelle Thew, Michael Balls

Laboratory Experiments Collection

Dogs remain the main non-rodent species in preclinical drug development. Despite the current dearth of new drug approvals and meagre pipelines, this continues, with little supportive evidence of its value or necessity. To estimate the evidential weight provided by canine data to the probability that a new drug may be toxic to humans, we have calculated Likelihood Ratios (LRs) for an extensive dataset of 2,366 drugs with both animal and human data, including tissue-level effects and Medical Dictionary for Regulatory Activities (MedDRA) Level 1–4 biomedical observations. The resulting LRs show that the absence of toxicity in dogs provides virtually no …

Discrimination Of Familiar Human Faces In Dogs (Canis Familiaris), Ludwig Huber, Anaïs Racca, Billy Scaf, Zsófia Virányi, Friederike Range

Recognition Collection

Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also …

Semantics-Empowered Big Data Processing With Applications, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

We discuss the nature of Big Data and address the role of semantics in analyzing and processing Big Data that arises in the context of Physical-Cyber-Social Systems. We organize our research around the Five Vs of Big Data, where four of the Vs are harnessed to produce the fifth V - value. To handle the challenge of Volume, we advocate semantic perception that can convert low-level observational data to higher-level abstractions more suitable for decision-making. To handle the challenge of Variety, we resort to the use of semantic models and annotations of data so that much of the intelligent processing …

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous and …

Prenatal Development: Annotated Bibliography, Victoria J. Molfese, Amanda Prokasky, Kathleen Moritz Rudasill, Ibrahim H. Acar, Xiaoqing Tu, Kate Sirota, Brian Keiser

Department of Child, Youth, and Family Studies: Faculty Publications

For decades, researchers have investigated how events in the prenatal period impact women and their infants. These studies, particularly by researchers in the medical, neuroscience, and behavioral science fields, led to discoveries of important information regarding the prenatal events that were strongly associated with mortality (or death) and morbidity (or incidences of injury, pathology and abnormalities/anomalies, and neurobehavioral sequelae) in the neonatal and infancy periods. Among the many common findings from early research studies, two are particularly noteworthy. First, maternal and fetal risk conditions arising in the prenatal period do not do so in isolation. Sameroff and Chandler characterized this …

At its best, a university is a collection of individuals ‐‐ students and faculty ‐‐ focused on learning and discovering new knowledge. For this goal to be realized, a critical element is having faculty members deeply engaged with their disciplines. Scholarship, in the form of journal articles, book chapters, monographs and similar endeavors, creative activity which can take an even wider range of forms, and funded research which explores the boundaries of their disciplines all contribute to such engagement. Through such participation, faculty members stay at the growing edges of their fields, and in so doing, they enrich their intellectual …

Early Humboldtian Influences On Alfred Russel Wallace's Scheme Of Nature [Presented At The Alfred Russel Wallace And His Legacy Royal Society Of London Meeting, 21 October 2013], Charles H. Smith

DLPS Faculty Publications

Alfred Russel Wallace’s 1858 Ternate paper on natural selection is a famous work in the history of science. Beyond his co-discovery of the principle, moreover, Wallace is known for a large number of early applications of the idea, both to biological and biogeographical subjects. Yet how much do we really know about Wallace’s own evolution of thought, and his actual intentions before his views were swallowed up by the inertia of Darwin’s revolution? A number of differences between Wallace’s and Darwin’s views are apparent and have been much treated over the years, but related discussions dwell more on effects than …

Predator Recognition In Rainbowfish, Melanotaenia Duboulayi, Embryos, Lois J. Oulton, Vivian Haviland, Culum Brown

Aquaculture Collection

Exposure to olfactory cues during embryonic development can have long term impacts on birds and amphibians behaviour. Despite the vast literature on predator recognition and responses in fishes, few researchers have determined how fish embryos respond to predator cues. Here we exposed four-day-old rainbowfish (Melanotaenia duboulayi) embryos to cues emanating from a novel predator, a native predator and injured conspecifics. Their response was assessed by monitoring heart rate and hatch time. Results showed that embryos have an innate capacity to differentiate between cues as illustrated by faster heart rates relative to controls. The greatest increase in heart rate occurred in …

City Notifications As A Data Source For Traffic Management, Pramod Anantharam, Biplav Srivastava

Kno.e.sis Publications

A common problem for cities of developing countries like India in managing traffic is the lack of basic automated instrumentation to track road conditions or vehicle locations. Still, to help their citizens make informed travel decisions based on changing city dynamics; many cities have an authorized, city-initiated, notification service in place to alert subscribing commuters about road conditions. Here, alternative means may be used to create informal textual notifications e.g., inputs from field personnel, citizen updates, and pre-authorized events from city calendar. In this paper, we show that collections of such notifications, when processed with information extraction techniques, can turn …
