Temporal Patterns Of Happiness And Information In A Global Social Network: Hedonometrics And Twitter, Peter Sheridan Dodds, Kameroncker Decker Harris, Isabel M. Kloumann, Catherine A. Bliss, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

Individual happiness is a fundamental societal metric. Normally measured through self-report, happiness has often been indirectly characterized and overshadowed by more readily quantifiable economic indicators such as gross domestic product. Here, we examine expressions made on the online, global microblog and social networking service Twitter, uncovering and explaining temporal variations in happiness and information levels over timescales ranging from hours to years. Our data set comprises over 46 billion words contained in nearly 4.6 billion expressions posted over a 33 month span by over 63 million unique users. In measuring happiness, we construct a tunable, real-time, remote-sensing, and non-invasive, text-based …

Using Gis To Determine The Influence Of Wetlands On Cayuga Iroquois Settlement Location Strategies, David J. Birnbaum

HIM 1990-2015

The archaeological record of the Iroquois supports that settlements were regularly relocated during the protohistoric period (1500-1650 A.D.). With the use of Geographic Information Systems (GIS) computer software, archaeologists may analyze variables potentially resulting in or influencing the movement of settlements. Through the use of spatial analysis, I argue that Cayuga Iroquois settlement locations were influenced by the environmental characteristics of their surrounding landscape. Specifically, wetlands are believed to have influenced settlement location choices in central New York state. This study examines the spatial relationships between wetland habitats and protohistoric period Cayuga Iroquois settlements where swidden maize agriculture comprised most …

Structural Determinants Of Homicide: The Big Three, Maria Tcherni

Criminal Justice Faculty Publications

Building upon and expanding the previous research into structural determinants of homicide, particularly the work of Land, McCall and Cohen (1990), the current paper uses county-level data to disentangle three major influences on homicide rates: poverty, racial composition, and the disruption of family structure. Theoretical foundations of these influences are laid out, and the effects of the three factors on homicide rates are tested at two time periods as far removed from one another as possible: 1950-1960 and 1995-2005. All major variables typically used in homicide research are included as controls. The results of analyses show that the effects of …

Time Use And Food Pattern Influences On Obesity, Jane M. Kolodinsky, Amanda B. Goldstein

College of Agriculture and Life Sciences Faculty Publications

The rise of obesity in the United States over the past 25 years has resulted in an increase in the number of research studies published related to the causes, consequences, and possible solutions to the problem. Most would agree that obesity is a multi-dimensional problem that requires a range of solutions related to individual diet and activity, food and built environment, and public policy. Examination of complex relationships between food choice, time use patterns, sociodemographic characteristics and obesity has been limited by data availability and disciplinary focus. Using the theory of the production of health capital, this paper links empirical …

Heating Up The Forest: Open-Top Chamber Warming Manipulation Of Arthropod Communities At Harvard And Duke Forests, Shannon L. Pelini, Francis P. Bowles, Aaron M. Ellison, Nicholas J. Gotelli, Nathan J. Sanders, Robert R. Dunn

College of Arts and Sciences Faculty Publications

1.Recent observations indicate that climatic change is altering biodiversity, and models suggest that the consequences of climate change will differ across latitude. However, long-term experimental field manipulations that directly test the predictions about organisms' responses to climate change across latitude are lacking. Such experiments could provide a more mechanistic understanding of the consequences of climate change on ecological communities and subsequent changes in ecosystem processes, facilitating better predictions of the effects of future climate change. 2.This field experiment uses octagonal, 5-m-diameter (c.22m 3) open-top chambers to simulate warming at northern (Harvard Forest, Massachusetts) and southern (Duke Forest, North Carolina) hardwood …

Social Goals In Urban Physical Education: Relationships With Effort And Disruptive Behavior, Alex C. Garn, Nate Mccaughtry, Bo Shen, Jeffrey J. Martin, Mariane Fahlman

Kinesiology, Health and Sport Studies

This study investigated the relationships among four distinct types of social goals, effort, and disruptive behavior in urban physical education. Social responsibility, affiliation, recognition, status goals, along with effort and disruptive behavior in physical education were reported by high school physical education students (N = 314) from three urban schools. Findings from correlation and structural equa- tion modeling analyses revealed that social responsibility goals had a positive relationship with effort and an inverse relationship with disruptive behavior. Social status goals demonstrated a positive relationship with disruptive behavior and no relationship with effort. Social recognition goal results were mixed, as …

La Etnia Y Las Cesáreas En Los Partos En El Hospital Público De Arica, Chile, Marisa Westbrook

Independent Study Project (ISP) Collection

The principal objective of this project was to explore the relationship between ethnicity and the causes for Caesarean section in the regional public hospital in Arica, Chile. All births recorded in the maternity register (n=907) were analyzed over a 4-month period in 2011. The regional public hospital had a 27% caesarean section rate, higher than the WHO-recommended 15%. Last names were analyzed and deemed to be either of Aymara descent (n=275) or of European descent (n=632) based on criteria used from CONADI, the National Corporation for Indigenous Development. The overall rate of Caesarean section did not differ between Aymara and …

Religion And Infant Mortality In The U.S.: A Preliminary Study Of Denominational Variations, John P. Bartkowski, Xiaohe Xu, Ginny Garcia-Alexander

Sociology Faculty Publications and Presentations

Prior research has identified a number of antecedents to infant mortality, but has been focused on either structural (demographic) forces or medical (public health) factors, both of which ignore potential cultural influences. Our study introduces a cultural model for explaining variations in infant mortality, one focused on the role of community-level religious factors. A key impetus for our study is well-established religious variations in adult mortality at the community level. Seeking to extend the growing body of research on contextual-level effects of religion, this study examines the impact of religious ecology (i.e., the institutional market share of particular denominational traditions) …

Personality Traits Predict Hierarchy Rank In Male Rainbowfish Social Groups, Mathieu Colléter, Culum Brown

Sentience Collection

Personality traits are becoming increasingly important in explaining adaptive individual differences in animal behaviour and probably represent a leading edge of the evolutionary process. Despite the newfound interest in animal personality among behavioural ecologists, fewstudies have investigated the link between personality traits and fitness measures. We examined this link using male rainbowfish, Melanotaenia duboulayi, as a model species and found that a range of personality traits (aggression, activity and boldness) covaried with a male’s position in a hierarchy, which is directly related to reproductive success in this and many other species. Dominant fish were more aggressive, active, bold and also …

The Ecology Of San Luis Obispo: A Children's Book, Heidi Van Campen

Social Sciences

San Luis Obispo is one of the most loved places in the world by its residents and visitors. Located halfway between San Francisco and Los Angeles, San Luis Obispo is the heart of California's Central Coast. However, this paper is not about the present-day cities or residents. It is an ecological history; the story of life and land over time.

Historians tend to treat nature as the setting for history, rather than a participant. Ecology is a history written knowing that we shape our environment and it shapes us.

This is a story of the ecology of San Luis Obispo.

Particle Size, Critical Shear Stress, And Benthic Invertebrate Distribution And Abundance In A Gravel-Bed River Of The Southern Appalachians, Helen Mayoral

Geosciences Theses

To determine the relationship between the abundance and density of benthic invertebrates, and the critical shear stress of individual grain sizes, a reach along Smith Creek, was divided into ten 2m x 2m quadrants. Within each quadrant, five randomly selected clasts for each grain size ranging from 2.26 to 25.6 cm were cleaned for benthic invertebrates. Wolman pebble counts for each quadrant were also conducted and used to determine the critical Shields stress per grain size fraction from the model given by Wiberg and Smith (1987) that explicitly accounts for particle hiding/sheltering effects in mixed-bed rivers. Particle entrainment values were …

Town Of Braintree - Monatiquot River Watershed Study, Benjamin D'Agostino, Elizabeth A. Englebretson, Carli Foster, Jeffrey Scott Fulford, Edward P. Haynes, Tracy Murphy, Sparky Vonplinsky, Eric Wojtowicz

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

Monatiquot River has played an important role in the Town of Braintree’s great industrial history. Over time, people’s relationship with the river has evolved from daily necessity and industrial utilitarian usage to scenery and recreational amenity. Currently, there is limited public physical access to the water and a lack of connection to regional greenway system. In addition, the extreme flood in March 2010 signified the prolonged urbanization impacts on floodplains and massive impervious surfaces in the watershed. Under the climate change effects, Braintree is likely to face more frequent and severe storms that affect safety and welfare of the increasing …

Information-Seeking Behaviors Of First-Semester Veterinary Students: A Preliminary Report, Sharon A. Weiner, Gretchen Stephens, Abdelfattah Y.M. Nour

Libraries Faculty and Staff Scholarship and Research

Although emphasis in veterinary education is increasingly being placed on the ability to find, use, and communicate information, studies on the information behaviors of veterinary students or professionals are few. Improved knowledge in this area will provide valuable information for course and curriculum planning and the design of information resources. This article describes a survey of the information-seeking behaviors of first-semester veterinary students at Purdue University. A survey was administered as the first phase of a progressive semester-long assignment for a first semester DVM course in systemic mammalian physiology. The survey probed for understanding of the scientific literature and its …

Beliefs About Racism And Health Among African American Women With Diabetes: A Qualitative Study, Julie A. Wagner, Lisa M. Budris, Sophia Belay, Howard A. Tennen

UCHC Articles - Research

Exposure to racism has been linked to poor health outcomes. Little is known about the impact of racism on diabetes outcomes. This study explored African American (AA) women’s beliefs about how racism interacts with their diabetes self-management and control. Four focus groups were conducted with a convenience sample of 28 adult AA women with type 2 diabetes who were recruited from a larger quantitative study on racism and diabetes. The focus group discussions were transcribed verbatim and analyzed by the authors. Women reported that exposure to racism was a common phenomenon, and their beliefs did in fact link racism to …

Review Of: "Escape From The Ivory Tower: A Guide To Making Your Science Matter", By Nancy Baron, Mark W. Neff

Environmental Studies Faculty and Staff Publications

Collectively, ecologists produce a staggering amount of information each year. Using the Web of Science Journal Citation Reports subject classification to define the field of ecology, our discipline comprises 129 ecology-specific journals that in 2009 published an astounding 14 280 articles. How much of that information is being used by policymakers? How much is potentially useful to those audiences? The message in Nancy Baron’s new book, Escape from the ivory tower: a guide to making your science matter, is that all of it could be taken up by the media, publicized, and utilized by policymakers if only we could …

An Ecological Analysis Of Social And Economic Influences On Black And White Infant Mortality Risk In Orange County, Fl, Littleton, Vanessa Lopez

Electronic Theses and Dissertations

Black health disparities are a salient public health issue with blacks in every socioeconomic level at a greater health disadvantage than their white counterparts. In particular, disparity in infant mortality rates between blacks and whites have widened in recent decades to differentials never before experienced in the United States. Social ecologists investigating the myriad of individual and environmental risk factors have failed to fully account for the persistent differential. This study examines the relationships between individual and environmental influences on the health risk experienced by blacks, whites, as well as the differential between the two populations. This multi-level analysis was …

Epistemic Fault Lines In Biomedical And Social Approaches To Hiv Prevention, Barry D. Adam

Sociology, Anthropology, and Criminology Publications

This paper raises the question of how knowledge creation is organized in the area of HIV prevention and how this concatenation of expertise, resources, at-risk people and viruses shapes the knowledge used to impede the epidemic. It also seeks to trouble the discourses of biomedical pre-eminence in the field of HIV prevention by examining the claim for treatment as prevention, looking at evidence constructed through the biomedical frame and through the lens of the sociology of science. These questions lie within a larger socio-historical context of lagging worldwide attention and funding to prevention in the HIV area and, in particular, …

Coping With Forest Fragmentation: A Comparison Of Colobus Angolensis Palliatus Dietary Diversity And Behavioral Plasticity In The East Sagara Forest, Tanzania., Noah T. Dunham

Honors Projects

Habitat destruction and forest fragmentation are perhaps the largest threats to primate species around the world. While national parks, games reserves, and primate sanctuaries are instrumental in primate conservation, research suggests that some non-governmentally protected forest fragments may also serve as viable habitats for primates. Of course not all primates respond to fragmentation in the same way, but a species’ ability to survive in a fragment relates to 1) home range size 2) degree of frugivory 3) dietary flexibility and behavioral plasticity and 4) ability to utilize matrix habitats. Here I describe these variables in relation to black and white …

Profiles In Science For Science Librarians: "What Lives Where, And Why": Alfred Russel Wallace, And The Field Of Biogeography, Charles H. Smith

DLPS Faculty Publications

Biogeography, the study of animal and plant distribution, has a history extending back to at least the eighteenth century. But it was not until the work of Charles Darwin and Alfred Russel Wallace in the mid-nineteenth century that it really came into its own as a science. Darwin’s importance notwithstanding, it was really Wallace who put the field on the map, and many of today’s research threads can be traced back to his influence. This article provides a summary review of Wallace’s life and work and biogeography as a field of study, including Wallace’s role in its development.

Ontario Public Libraries, Accessibility, And Justice: A Capability Approach., Heather Hill

FIMS Publications

The Access for Ontarians with Disabilities Act is developing standards for accessibility across the province. The Canadian Library Association has had service standards in place since 1997, so addressing accessibility in Ontario libraries is nothing new. Public libraries are, however facing new challenges to providing service as they transition from non-binding library association policy to binding legislation. This paper outlines a study of accessibility in Ontario public libraries through a capability approach lens as described by Amartya Sen.

Physiological And Genetic Correlates Of Boldness: Characterising The Mechanisms Of Behavioural Variation In Rainbow Trout, Oncorhynchus Mykiss, Jack S. Thomson, Phillip C. Watts, T. G. Pottinger, Lynne U. Sneddon

Ethology Collection

Bold, risk-taking animals have previously been putatively linked with a proactive stress coping style whereas it is suggested shyer, risk-averse animals exhibit a reactive coping style. The aim of this study was to investigate whether differences in the expression of bold-type behaviour were evident within and between two lines of rainbow trout, Oncorhynchus mykiss, selectively bred for a low (LR) or high (HR) endocrine response to stress, and to link boldness and stress responsiveness with the expression of related candidate genes. Boldness was determined in individual fish over two trials by measuring the latency to approach a novel object. Differences …

Spring-Migration Ecology Of Northern Pintails In South-Central Nebraska, Aaron T. Pearse, Gary L. Krapu, Robert R. Cox Jr., Bruce E. Davis

USGS Northern Prairie Wildlife Research Center

Spring-migration ecology of staging Northern Pintails, Anas acuta, was investigated in south-central Nebraska, USA. Habitat associations, local movements, settling patterns, arrival dates, residency times and survival were estimated from 71 radiomarked pintails during spring 2001, 2003 and 2004, and diet determined from 130 females collected during spring 1998 and 1999. Seventy-two percent of pintail diurnal locations were in palustrine wetlands, 7% in riverine wetlands, 3% in lacustrine wetlands, 6% in municipal sewage lagoons and irrigation reuse pits and 10.5% in croplands. Emergent wetlands with hemi-marsh conditions were used diurnally more often than wetlands with either open or closed vegetation …

Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg

USGS Northern Prairie Wildlife Research Center

Minnesota wolves (Canis sp.) sometimes are reported to have affinity to a small, narrow-skulled eastern form (Canis lupus lycaon Schreber, 1775) and sometimes to a larger, broader western form (Canis lupus nubilus Say, 1823). We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970–1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and …

Wireless Telesurveillance System For Detecting Dementia, William D. Kearns, James L. Fozard, Vilis O. Nams, Jeffrey D. Craighead

William D. Kearns, PhD

Objective We hypothesized path tortuosity (an index of casual locomotor variability) measured by a movement telesurveillance system would be suitable for assisted living facility residents clinically diagnosed with dementia. Background We examined the relationship of dementia to path tortuosity and to movement speed and path length variability, both of which increase in dementia. Methods Daytime movements of 25 elders (19 female; 14 with dementia; average age 80.6) were monitored for 30 days using radio transponders measuring location with a maximum accuracy of 20 cm. After 30 days, the Mini Mental State Exam (MMSE) and Revised Algase Wandering Scale-Community Version (RAWS-CV) …

Do Fast Food Restaurants Cluster Around High Schools? A Geospatial Analysis Of Proximity Of Fast Food Restaurants To High Schools And The Connection To Childhood Obesity Rates, Hilary Nixon, Lauren Doud

Faculty Publications, Urban and Regional Planning

Nationwide, approximately 30% of children consume fast food on a typical day, and caloric intake from fast food has increased fivefold over the past three decades. Our analysis adds to a growing body of public health and planning research through a geospatial analysis of fast food restaurants in Santa Clara County, California. We selected 41 high schools, representing 97% of enrollment in the county, and examined proximity to fast food restaurants within 400 meters (437 yards) and 800 meters (875 yards) of the schools. Our results indicate that fast food restaurants are clustered near high schools with higher obesity rates. …
