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 …


Randomization Tests For Quantifying Species Importance To Ecosystem Function, Nicholas J. Gotelli, Werner Ulrich, Fernando T. Maestre Dec 2011

Randomization Tests For Quantifying Species Importance To Ecosystem Function, Nicholas J. Gotelli, Werner Ulrich, Fernando T. Maestre

College of Arts and Sciences Faculty Publications

1. Quantifying the contribution of different species to ecosystem function is an important challenge. We introduce simple randomization tests (and software) for quantifying the average effect of species on ecosystem variables measured in multiple plots with and without the presence of a particular species. These randomization tests formalize the analysis of uncontrolled 'natural experiments' and quantify species effects in standardized deviation units. 2.We tested the method with data on ecosystem function in biological soil crust assemblages of lichens in semi-arid gypsum outcrops in central Spain. In sixty-three 50cm×50cm sample plots, we measured the presence and percentage cover of 17 species …

Time Use And Food Pattern Influences On Obesity, Jane M. Kolodinsky, Amanda B. Goldstein Dec 2011

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 …


The Limits To Prediction In Ecological Systems, Brian Beckage, Louis J. Gross, Stuart Kauffman Nov 2011

The Limits To Prediction In Ecological Systems, Brian Beckage, Louis J. Gross, Stuart Kauffman

College of Agriculture and Life Sciences Faculty Publications

Predicting the future trajectories of ecological systems is increasingly important as the magnitude of anthropogenic perturbation of the earth systems grows.We distinguish between two types of predictability: the intrinsic or theoretical predictability of a system and the realized predictability that is achieved using available models and parameterizations. We contend that there are strong limits on the intrinsic predictability of ecological systems that arise from inherent characteristics of biological systems. While the realized predictability of ecological systems can be limited by process and parameter misspecification or uncertainty, we argue that the intrinsic predictability of ecological systems is widely and strongly limited …


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 Oct 2011

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 …


A Multicultural Grassroots Effort To Reduce Ethnic And Racial Social Distance Among Middle School Students, Christopher Donoghue, David Brandwein Sep 2011

A Multicultural Grassroots Effort To Reduce Ethnic And Racial Social Distance Among Middle School Students, Christopher Donoghue, David Brandwein

Department of Sociology Faculty Scholarship and Creative Works

Raising tolerance for people of different ethnic and racial groups is the goal of the Multicultural Mosaic program, a grass-roots multicultural education effort initiated by a small group of middle school teachers in a private school in the northeast. After years of enjoying the comforts of a modern, but European-based, curriculum, these teachers took the initiative to pursue an ambitious transformation of their entire school's approach to pedagogy. Not only would the English teachers introduce new texts by foreign authors and the social studies teachers introduce new materials on the history of non-Western cultures, but also the teachers of mathematics …


The High Costs Of Conserving Southeast Asia's Lowland Rainforests, Brendan Fisher, David P. Edwards, Xingli Giam, David S. Wilcove Aug 2011

The High Costs Of Conserving Southeast Asia's Lowland Rainforests, Brendan Fisher, David P. Edwards, Xingli Giam, David S. Wilcove

Rubenstein School of Environment and Natural Resources Faculty Publications

Mechanisms that mitigate greenhouse-gas emissions via forest conservation have been portrayed as a cost-effective approach that can also protect biodiversity and vital ecosystem services. However, the costs of conservation - including opportunity costs - are spatially heterogeneous across the globe. The lowland rainforests of Southeast Asia represent a unique nexus of large carbon stores, imperiled biodiversity, large stores of timber, and high potential for conversion to oil-palm plantations, making this region one where understanding the costs of conservation is critical. Previous studies have underestimated the gap between conservation costs and conversion benefits in Southeast Asia. Using detailed logging records, cost …


Subsurface Characterization Of Groundwater Contaminated By Landfill Leachate Using Microbial Community Profile Data And A Nonparametric Decision-Making Process, Andrea R. Pearce, Donna M. Rizzo, Paula J. Mouser Jun 2011

Subsurface Characterization Of Groundwater Contaminated By Landfill Leachate Using Microbial Community Profile Data And A Nonparametric Decision-Making Process, Andrea R. Pearce, Donna M. Rizzo, Paula J. Mouser

College of Engineering and Mathematical Sciences Faculty Publications

Microbial biodiversity in groundwater and soil presents a unique opportunity for improving characterization and monitoring at sites with multiple contaminants, yet few computational methods use or incorporate these data because of their high dimensionality and variability. We present a systematic, nonparametric decision-making methodology to help characterize a water quality gradient in leachate-contaminated groundwater using only microbiological data for input. The data-driven methodology is based on clustering a set of molecular genetic-based microbial community profiles. Microbes were sampled from groundwater monitoring wells located within and around an aquifer contaminated with landfill leachate. We modified a self-organizing map (SOM) to weight the …


Governance Informatics: Managing The Performance Of Inter-Organizational Governance Networks, Christopher Koliba, Asim Zia, Brian H.Y. Lee May 2011

Governance Informatics: Managing The Performance Of Inter-Organizational Governance Networks, Christopher Koliba, Asim Zia, Brian H.Y. Lee

College of Agriculture and Life Sciences Faculty Publications

This article introduces an informatics approach to managing the performance of inter-organizational governance networks that are designed to create, implement and evaluate public policies and the range of activities undertaken by practicing public administrators. We label this type of information flow process management "governance informatics" and lay out a range of theoretical constructs that may be used to collect, categorize, and analyze performance in inter-organizational governance networks. We discuss how governance informatics may be able to assess and re-design the accountability and transparency regimes of information flows in inter-organizational governance networks. The integration of a governance informatics-driven performance management system …


Larvicidal Effects Of Chinaberry (Melia Azederach) Powder On Anopheles Arabiensis In Ethiopia, Ryan E. Trudel, Arne Bomblies May 2011

Larvicidal Effects Of Chinaberry (Melia Azederach) Powder On Anopheles Arabiensis In Ethiopia, Ryan E. Trudel, Arne Bomblies

College of Engineering and Mathematical Sciences Faculty Publications

Background: Synthetic insecticides are employed in the widely-used currently favored malaria control techniques involving indoor residual spraying and treated bednets. These methods have repeatedly proven to be highly effective at reducing malaria incidence and prevalence. However, rapidly emerging mosquito resistance to the chemicals and logistical problems in transporting supplies to remote locations threaten the long-term sustainability of these techniques. Chinaberry (Melia azederach) extracts have been shown to be effective growth-inhibiting larvicides against several insects. Because several active chemicals in the trees' seeds have insecticidal properties, the emergence of resistance is unlikely. Here, we investigate the feasibility of Chinaberry as a …


Environmental Imaginaries Of The Middle East And North Africa, Diana K. Davis, Edmund Burke Iii Jan 2011

Environmental Imaginaries Of The Middle East And North Africa, Diana K. Davis, Edmund Burke Iii

Ohio University Press Open Access Books

The landscapes of the Middle East have captured our imaginations throughout history. Images of endless golden dunes, camel caravans, isolated desert oases, and rivers lined with palm trees have often framed written and visual representations of the region. Embedded in these portrayals is the common belief that the environment, in most places, has been deforested and desertified by centuries of misuse. It is precisely such orientalist environmental imaginaries, increasingly undermined by contemporary ecological data, that the eleven authors in this volume question. This is the first volume to critically examine culturally constructed views of the environmental history of the Middle …


Scientific Instruments For Climate Change Adaptation: Estimating And Optimizing The Efficiency Of Ecosystem Service Provision, Ferdinando Villa, Ken Bagstad, Gary Johnson, Brian Voigt Jan 2011

Scientific Instruments For Climate Change Adaptation: Estimating And Optimizing The Efficiency Of Ecosystem Service Provision, Ferdinando Villa, Ken Bagstad, Gary Johnson, Brian Voigt

Rubenstein School of Environment and Natural Resources Faculty Publications

Adaptation to the consequences of climate change can depend on efficient use of ecosystem services (ES), i.e. a better use of natural services through management of the way in which they are delivered to society. While much discussion focuses on reducing consumption and increasing production of services, a lack of scientific instruments has so far prevented other mechanisms to improve ecosystem services efficiency from being addressed systematically as an adaptation strategy. This paper describes new methodologies for assessing ecosystem services and quantifying their values to humans, highlighting the role of ecosystem service flow analysis in optimizing the efficiency of ES …


Incorporating Systems Thinking And Sustainability Within Civil And Environmental Engineering Curricula At Uvm, Nancy J. Hayden, Donna M. Rizzo, Mandar M. Dewoolkar, Lalita Oka, Maureen Neumann Jan 2011

Incorporating Systems Thinking And Sustainability Within Civil And Environmental Engineering Curricula At Uvm, Nancy J. Hayden, Donna M. Rizzo, Mandar M. Dewoolkar, Lalita Oka, Maureen Neumann

College of Engineering and Mathematical Sciences Faculty Publications

As part of an NSF Department Level Reform (DLR) grant, the civil and environmental engineering programs at the University of Vermont (UVM) incorporated systems thinking and a systems approach to engineering problem solving within their programs. A systems thinking approach regards social, environmental and economic factors as necessary components of the problem solution. Because it is a whole systems approach it also encompasses sustainability. We have integrated systems thinking in the following ways; 1) new material has been included into key courses (e.g. the first-year introductory and senior design courses), 2) a sequence of three related environmental and transportation systems …


Enhancing Marital Enrichment Through Spirituality: Efficacy Data For Prayer Focused Relationship Enhancement, Steven R. Beach, Tera R. Hurt, Frank D. Fincham, Kameron J. Franklin, Lily M. Mcnair, Scott M. Stanley Jan 2011

Enhancing Marital Enrichment Through Spirituality: Efficacy Data For Prayer Focused Relationship Enhancement, Steven R. Beach, Tera R. Hurt, Frank D. Fincham, Kameron J. Franklin, Lily M. Mcnair, Scott M. Stanley

Tera R. (Hurt) Jordan

We examined 393 African American married couples assigned to (a) a culturally sensitive version of a widely disseminated relationship enhancement program (CS-PREP) (b) a similar version of the same program that also included a focus on prayer (PFP condition), or (c) an information-only control condition in which couples received a self-help version of the same program. Husbands averaged 40.5 years of age and wives averaged 38.9 years. We found a significant interaction between intervention and time of assessment, reflecting group differences in linear trends for the three conditions, with the two intervention conditions performing better than the control condition, and …


Integration Management For Green Business To Achieve Sustainability And Buildability, Low Sui Pheng, Ng Wei Chen Jan 2011

Integration Management For Green Business To Achieve Sustainability And Buildability, Low Sui Pheng, Ng Wei Chen

Business Review

The Building Control (Environmental Sustainability) Regulations, introduced in 2008, require buildings to attain minimum scores under the Green Mark Scheme (GMS) in Singapore. The Building Control (Buildable Design) Regulations, introduced in 2001, require buildings to attain minimum buildability scores under the Buildable Design Appraisal System (BDAS) in Singapore. It appears that both the GMS and BDAS can influence building designs and must therefore be considered concurrently to yield the optimal results. Consideration of both sets of requirements is illustrated using a case study of one 18-storey residential building. Through interviews, the study also explores the issues relating to integration management …


Cross-Scale Value Trade-Offs In Managing Social-Ecological Systems: The Politics Of Scale In Ruaha National Park, Tanzania, Asim Zia, Paul Hirsch, Alexander Songorwa, David R. Mutekanga, Sheila O'Connor, Thomas Mcshane, Peter Brosius, Bryan Norton Jan 2011

Cross-Scale Value Trade-Offs In Managing Social-Ecological Systems: The Politics Of Scale In Ruaha National Park, Tanzania, Asim Zia, Paul Hirsch, Alexander Songorwa, David R. Mutekanga, Sheila O'Connor, Thomas Mcshane, Peter Brosius, Bryan Norton

College of Agriculture and Life Sciences Faculty Publications

Management of social-ecological systems takes place amidst complex governance processes and cross-scale institutional arrangements that are mediated through politics of scale. Each management scenario generates distinct cross-scale trade-offs in the distribution of pluralistic values. This study explores the hypothesis that conservation-oriented management scenarios generate higher value for international and national scale social organizations, whereas mixed or more balanced management scenarios generate higher value for local scale social organizations. This hypothesis is explored in the management context of Ruaha National Park (RNP), Tanzania, especially the 2006 expansion of RNP that led to the eviction of many pastoralists and farmers. Five management …

A Cafeteria-Based Tasting Program Improved Elementary School Children's Fruit Preferences And Self-Efficacy To Consume Fruits And Vegetables, Wei-Ping Wong

LSU Master's Theses

This quasi-experimental study examined the impact of a fruit and vegetable (FV) tasting program on third and fifth grade children’s preferences and psychosocial factors associated with FV intake. Four public schools in southeastern Louisiana participated. Two schools served as the intervention group where children were given a taste of four fruits or four vegetables on a rotating schedule for eight weeks followed by two weeks of tasting four months post- intervention (follow-up). Two control schools did not participate in tasting but received brightly colored FV posters which were posted in the cafeteria each week. A questionnaire administered at baseline, post-intervention, …


La Ola Verde: Female, Hispanic Consumers And The Green Movement, Stefanie Ann Ramirez Jan 2011

La Ola Verde: Female, Hispanic Consumers And The Green Movement, Stefanie Ann Ramirez

LSU Master's Theses

Due to their impact on the environment, apparel companies have gradually begun to change manufacturing and production processes and provide consumers with environmentally responsible apparel product options. Among these consumers are Hispanics, a consumer group which research has shown to have a strong purchasing power and astounding population increase. Between 2000 and 2010, the total population in the United States increased by 23.7million people, with Hispanics accounting for over 50% of that total increase (Humes, Jones, & Ramirez, 2011). It is estimated that by 2125 Hispanics will account for 50% of the total U.S. population (Day, 1996). Additionally, between 1990 …


Fostering Compliance In Preschool-Aged Children Using Least-To-Most Assistive Prompt Hierarchy, Courtney Powers Jan 2011

Fostering Compliance In Preschool-Aged Children Using Least-To-Most Assistive Prompt Hierarchy, Courtney Powers

LSU Master's Theses

Previous research has shown that prompting can increase child compliance to adult directives (Tarbox, Wallace, Penrod, & Tarbox, 2007; Wilder & Atwell, 2006; Wilder, Atwell, & Wine, 2006). The purpose of this study was to train teachers to use prompting to increase child compliance to teacher directives. This study builds on the current literature by using least-to-most prompting (Horner & Keilitz, 1975) within the naturally occurring context of the preschool classroom. The participants consisted of 3 preschool teachers who interacted with a target child in an early childhood classroom. Child compliance was measured during free choice center time. Results were …


The Role Of Ad-36 And Its E4orf-1 Protein In Modulating Glycemic Control, Emily Jane Dhurandhar Jan 2011

The Role Of Ad-36 And Its E4orf-1 Protein In Modulating Glycemic Control, Emily Jane Dhurandhar

LSU Doctoral Dissertations

Current treatment strategies for Type 2 Diabetes Mellitus (T2DM) include a range of anti-diabetic drugs, supplemented by lifestyle modifications to reduce dietary fat intake and body fat. However, for their anti-diabetic action, most drugs recruit insulin signaling pathways, which are already impaired in T2DM. Also, compliance and success in achieving sustained improvements in diet or obesity over the long term is marginal. Therefore, an agent that improves diabetes independent of insulin signaling or lifestyle changes may be highly useful. Human adenovirus Ad36 offers such a model. Ad36 improves glycemic control in chow-fed mice or rats and attenuates diabetes and hepatic …


Loving Me Or Loving You: Influencing The Attitudes And Behaviors Of Children Through A Prosocial Intervention, Shawna H. Gose Jan 2011

Loving Me Or Loving You: Influencing The Attitudes And Behaviors Of Children Through A Prosocial Intervention, Shawna H. Gose

LSU Master's Theses

Research indicates that narcissism may increase antisocial tendencies in children as young as preschool. In this quasi-experimental study, manners lessons on selfless, prosocial behavior were used as an intervention to decrease narcissism and antisocial behavior within second and third grade classrooms. Manners lessons provided children with opportunities to demonstrate prosocial attitudes toward others and thus were expected to decrease narcissism, increase empathy, decrease conduct problems and peer problems, and increase prosocial behavior. The present intervention positively influenced the external behavior of children as indicated by a decrease in conduct problems and peer problems and an increase in prosocial behavior for …

Chinese Influence On Western Women's Dress In American Vogue Magazine, 1960-2009, Yao Zeng

LSU Doctoral Dissertations

Chinese culture has dramatically influenced Western women’s fashionable dress over many centuries. Researchers have studied Chinese dress and its influence on Western women’s dress in the eighteenth, nineteenth, and early twentieth century. However, no research has systematically examined Chinese dress influences on Western women’s dress from the time that China reopened its door to the West in the 1970s and into the twenty-first century. The purpose of this study is to trace Chinese influence in Western women’s dress from 1960 to 2009 in American Vogue magazine. The specific aims of this study are to identify and record the influence of …


An Investigation Of The Home And Family Questionnaire's Concurrent And Predictive Validity, Angel Lewis Herring Jan 2011

An Investigation Of The Home And Family Questionnaire's Concurrent And Predictive Validity, Angel Lewis Herring

LSU Doctoral Dissertations

The current study sought to replicate the findings of Pierce, Alfonso, & Garrison (1998) that constructed and tested the Home and Family Questionnaire (HFQ). More specifically, the internal consistency of the HFQ’s three subscales, Maturity Facilitation, Child’s Use of Stimulating Materials, and the Parent-Child Emotional Relationship, was investigated. Construct validity of the HFQ was investigated by correlating the HFQ subscale scores to the Parenting Styles Dimensions Questionnaire (PSDQ) subscale scores (Robinson, Mandleco, Olsen & Hart, 1995). Criterion-related validity was investigated by correlating the HFQ subscale scores with the Pictorial Scales of Perceived Competence and Social Acceptance in Young Children (PSPC) …


Contextual Influences On Faith Development In Adolescents And Emerging Adults, Katheryn A. Barker Jan 2011

Contextual Influences On Faith Development In Adolescents And Emerging Adults, Katheryn A. Barker

LSU Master's Theses

Recent research has revealed that high religiosity is associated with positive life outcomes in adolescents and emerging adults. However, the mechanisms and processes that underscore faith development, which is crucial to experiencing these outcomes, are not well understood. Furthermore, most research on faith development in adolescents and emerging adults is based on quantitative data and fails to examine the influence of developmental contexts on faith development. To address this, a racially diverse New England sample of 30 highly religious Christian, Jewish, New World faiths, and Muslim families were interviewed regarding their faith and family life. Focusing specifically on the faith …


Building Children's Liking And Preferences For Fruits And Vegetables Through School-Based Interventions, Anantha Padmaja Lakkakula Jan 2011

Building Children's Liking And Preferences For Fruits And Vegetables Through School-Based Interventions, Anantha Padmaja Lakkakula

LSU Doctoral Dissertations

Children’s food preferences play a major role in their food choices and consumption. The objectives of these studies were to examine the relationship between children’s preferences for fruits and vegetables (FV) and their weight status and to increase children’s liking of FV by offering repeated opportunities to taste less liked items. A representative sample of elementary school children (1st, 3rd, 4th, and 5th grades) were recruited in the three interventions. In the first study, 341 fourth- and fifth-grade children (43% boys; 68% 4th graders) were measured for height and weight and completed a survey which sought their preferences for 38 …


Investigating The Validity Of Scores Obtained With The Home And Family Questionnaire And Their Reliability With Scores Obtained With The Home Observation For The Measurement Of The Environment-Middle Childhood, Holly Marie Bell Jan 2011

Investigating The Validity Of Scores Obtained With The Home And Family Questionnaire And Their Reliability With Scores Obtained With The Home Observation For The Measurement Of The Environment-Middle Childhood, Holly Marie Bell

LSU Doctoral Dissertations

The study of home environments and their relationships to child outcomes has become common practice among researchers of child development. As such, having a reliable instrument for measuring home environments that is also cost and time efficient is of primary interest to researchers. The most widely used instrument for measuring home environments is the Home Observation Measurement of the Environment (HOME) developed by Caldwell and Bradley in 1984. Use of the HOME is prevalent among researchers, yet it is costly to implement both in time and in money. An alternative tool for home environment measurement is the Home and Family …


Investigating Early Childhood Teachers' Stress And Social Supports: A Multi-Methods Approach, Ashley Diane Romero Jan 2011

Investigating Early Childhood Teachers' Stress And Social Supports: A Multi-Methods Approach, Ashley Diane Romero

LSU Master's Theses

Previous research has indicated that teaching is a high stress profession and that social supports may help to mediate teacher job stress. Ecological maps have been used in both research and other fields in order to study individuals’ social networks. Using a sample of ten Pre-K teachers, this study aims to answers two questions of inquiry: 1) Is the amount of reported social supports for Pre-K teachers negatively associated with reported stress?, and 2) What information does the eco-map interview give us about teacher’s social supports and stress? A multi-methods approach of both qualitative and quantitative techniques was used in …


Obesity Treatment Alternatives: Foods To Surgery, Brooke Erwin Bayham Jan 2011

Obesity Treatment Alternatives: Foods To Surgery, Brooke Erwin Bayham

LSU Master's Theses

The purpose of these studies was to explore the roles of dietary strategies and bariatric surgery in obesity treatment. The breakfast study was a randomized, crossover trial used to evaluate the role of egg proteins, and a retrospective chart review was conducted to obtain comparative information about two different bariatric surgeries. The breakfast study included 20 subjects who were randomized to receive an egg breakfast (EB) or a cereal breakfast (CB) matched for energy density and macronutrient composition but different protein quality for one week. Following a washout period, each subject was crossed over to receive the opposite breakfast for …


Resistant Starch In The Diet Of Rodents Promotes An Increase In Fermentation And A Reduction In Body Fat In An Animal Model Of Dietary Obesity, Jason Andrew Charrier Jan 2011

Resistant Starch In The Diet Of Rodents Promotes An Increase In Fermentation And A Reduction In Body Fat In An Animal Model Of Dietary Obesity, Jason Andrew Charrier

LSU Master's Theses

In previous studies, in has been observed that the addition of resistant starch (RS) in the diet of rodents, a non-digestible fermentable fiber, promotes increases in markers of fermentation and improvements in body weight and body fat analysis when incorporated into low to moderate fat diets. This study investigated whether the same beneficial effects observed with RS addition in these lower fat diets could be obtained in a high fat diet, and if the type of fatty acid consumed in the diet makes a difference in markers of fermentation and body fat. Sprague Dawley rats (n=96) were fed as weight …
