Influence Of –Carrageenan, Pectin, And Gelatin On The Physicochemical Properties And Stability Of Milk Protein-Stabilized Emulsions, M. Tippetts, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study evaluated the stability of bilayer emulsions as a function of secondary layer composition and pH. Primary emulsions were formulated with 5% soybean oil, 1% protein from nonfat dry milk (NDM) powder as emulsifier and ι-carrageenan (ι-carr), low-methoxyl pectin (LMp), high-methoxyl pectin (HMp), or gelatin as secondary layers. ζ-Potential values increased for each emulsion as the pH decreased, with ι-carr emulsions being consistently more negatively charged than primary emulsions and significantly more stable. ζ-Potential values were not always correlated to emulsion stability. Gelatin secondary emulsions at pH 3 and HMp secondary emulsions at pH 7 were unstable due to …

Identification And Quantification Of Flavor Attributes Present In Chicken, Lamb, Pork, Beef, And Turkey, Curtis Maughan, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

The objectives of this study were to use a meat flavor lexicon to identify and quantify flavor differences among different types of meats such as beef, chicken, lamb, pork, and turkey, and to identify and quantify specific flavor attributes associated with “beef flavor” notes. A trained descriptive panel with 11 participants used a previously developed meat lexicon composed of 18 terms to evaluate the flavor of beef, chicken, pork, turkey, and lamb samples. Results show that beef and lamb samples can be described by flavor attributes such as barny, bitter, gamey, grassy, livery, metallic, and roast beef. Inversely related to …

Optimal Growth Oflactobacillus Casei In A Cheddar Cheese Ripening Model System Requires Exogenous Fatty Acids, W. S. Tan, M. F. Budinich, Robert E. Ward, Jeff Broadbent, J. L. Steele

Nutrition, Dietetics, and Food Sciences Faculty Publications

Flavor development in ripening Cheddar cheese depends on complex microbial and biochemical processes that are difficult to study in natural cheese. Thus, our group has developed Cheddar cheese extract (CCE) as a model system to study these processes. In previous work, we found that CCE supported growth of Lactobacillus casei, one of the most prominent nonstarter lactic acid bacteria (NSLAB) species found in ripening Cheddar cheese, to a final cell density of 108 cfu/mL at 37°C. However, when similar growth experiments were performed at 8°C in CCE derived from 4-mo-old cheese (4mCCE), the final cell densities obtained were only about …

Understanding Precision Nitrogen Stress To Optimize The Growth And Lipid Content Tradeoff In Green Algae, Curtis Adams, Bruce Bugbee

Algae and Biofuel

Precision N stress can be used to optimize growth and lipid content tradeoffs. Optimization requires low-level stress for some, high-level for others. Species selection should be broadened to include concurrent growth and lipid accumulation, as well as response to minimal N stress. N deprivation is a viable method for increasing lipid productivity. There is great promise among the natural species.

Unmasking Children's Agency, David F. Lancy

Sociology, Social Work and Anthropology Faculty Publications

The goal of this paper is to identify (unmask) and critique the movement to promote children’s agency as a cornerstone of research, care, education and intervention with children. The article makes a case that this movement is harmful to a scientific approach to the study of childhood, distorts or ignores key understandings of the evolution of childhood and culture. The article demonstrates that the agency movement is ethnocentric, classist and hegemonic representing the dominance of contemporary bourgeoisie child-rearing. It imposes a single, privileged ethnotheory of childhood upon the diverse societies of the world with alternative ethnotheories and practices. Lastly, the …

Sociology, Social Work and Anthropology Faculty Publications

Cultural ecosystem services (ES) are consistently recognized but not yet adequately defined or integrated within the ES framework. A substantial body of models, methods, and data relevant to cultural services has been developed within the social and behavioral sciences before and outside of the ES approach. A selective review of work in landscape aesthetics, cultural heritage, outdoor recreation, and spiritual significance demonstrates opportunities for operationally defining cultural services in terms of socioecological models, consistent with the larger set of ES. Such models explicitly link ecological structures and functions with cultural values and benefits, facilitating communication between scientists and stakeholders and …

The Frying Pan Or The Fire: Public Attitudes About Using Herbicides To Manage Invasive Weeds, Mariah Evans, Kimberly Rollins

Articles

How do we balance risks? This paper assesses hypotheses derived from instrumental rationality and risk society theories about the reasoning strategies that people will use to develop views supportive or oppositional to the use of herbicides to manage cheatgrass (Bromus tectorum), an invasive weed. Cheatgrass is well-known in the population of the American West to increase wildfire risks substantially and to harm the environment in other ways. But are the cures worse than the disease? One demonstrably effective method of cheatgrass suppression is the use of herbicides, and the paper explores sources of support for and opposition to …

Wittgensteinian Support For Domain Analysis In Classification, Andrew Wesolek

Library Faculty & Staff Publications

Hjorland contends that in order to further the goal of linking researchers to relevant information ‘domain analysis’ should be used in concept classification. He thinks that concept classification should not strive to classify on the basis of the properties of objects, but rather on descriptions of objects that are loosely derived from human activity and social negotiation. Currently, most information scientists operate under a ‘positivist’ view of concept classification, which, Hjorland maintains, mistakenly strives for universal classification schema while muddling the comprehension of individual researchers. Though he tends to include Wittgenstein in the positivist camp for classification, Hjorland’s domain analysis …

Widespread Triploidy In Western North American Aspen (Populus Tremuloides), Karen E. Mock, Colin M. Callahan, M. Nurul Islam-Faridi, John D. Shaw, Hardeep S. Rai, Stewart C. Sanderson, Carol A. Rowe, Ronald J. Rye, Michael D. Madritch, Richard S. Gardner, Paul G. Wolf

Biology Faculty Publications

We document high rates of triploidy in aspen (Populus tremuloides) across the western USA (up to 69% of genets), and ask whether the incidence of triploidy across the species range corresponds with latitude, glacial history (as has been documented in other species), climate, or regional variance in clone size. Using a combination of microsatellite genotyping, flow cytometry, and cytology, we demonstrate that triploidy is highest in unglaciated, drought-prone regions of North America, where the largest clone sizes have been reported for this species. While we cannot completely rule out a low incidence of undetected aneuploidy, tetraploidy or duplicated loci, our …

Apparent Prevalence Of Swine Brucellosis In Feral Swine In The United States, Kerri Pedersen, Sarah N. Bevins, Brandon S. Schmit, Mark W. Lutman, Michael P. Milleson, Clint T. Turnage, Troy T. Bigelow, Thomas J. Deliberto

Human–Wildlife Interactions

Samples were collected in 35 states as part of a national monitoring system to detect multiple diseases in feral swine (Sus scrofa). During March 2009 through December 2010, we collected serum samples from 4,479 feral swine from 13 states, and 159 animals tested were seropositive for brucellosis. No difference in likelihood of infection was found between males and females, but adults were more likely than sub-adults or juveniles to be exposed to brucellosis. Feral swine sampled during winter months also were more likely to be seropositive than animals sampled during other seasons. Apparent prevalence varied among states, and …

Factors Influencing Survival Of Desert Mule Deer In The Greater San Andres Mountains, New Mexico, Louis C. Bender, Brock D. Hoenes, Cristina L. Rodden

Human–Wildlife Interactions

Mule deer numbers have declined precipitously in the San Andres Mountains of southcentral New Mexico. To assess reasons for population declines, we monitored condition, survival, and causes of mortality for a range of 37 to 64 radio-collared, >1.5-year-old female mule deer annually, and a range of 14 to 31 radio-collared, >1.5-year-old male mule deer annually from 2003 to 2009, and modeled environmental factors affecting survival. We found annual survival rates of 0.74 to 0.86 for females and 0.74 to 0.92 for males, rates that were similar among years within sexes. Causes of mortality for 50 radio-collared females and 22 radio-collared …

Savanna Glade Hotspots: Plant Community Development And Synergy With Large Herbivores, Kari E. Veblen

Wildland Resources Faculty Publications

In African savannas, abandonment of traditional livestock corrals (bomas) creates long-term mosaics of nutrient hotspots embedded in a lower-nutrient matrix. It is unclear how plant communities develop over time on these sites in clay-rich “black cotton” soils or how herbivores attracted to these sites affect vegetation development. I first examined whether treeless “glades”, derived from abandoned bomas, function as nutrient and herbivore hotspots. Soil, vegetation, and herbivore data were collected on glades of varying ages. The results indicated that glades persist as long-term (≥four decades) patches (0.25–1.0 ha) of improved soil texture and increased nutrient levels, palatable grasses, and herbivore …

Delayed Nesting By Female Canada Geese (Branta Canadensis): Benefits And Costs, Michael R. Conover

Wildland Resources Faculty Publications

In many avian species, females do not nest the first year they attain sexual maturity. I examined the benefits and costs of delayed nesting in a nonmigratory population of Canada Geese (Branta canadensis) in New Haven County, Connecticut, from 1984 through 2008. I individually marked 381 female goslings and monitored them throughout their lives. Eighty-seven females were recruited into the local breeding population; 16 of these started nesting when 1 or 2 years old (young nesters), and 71 started nesting when 3 to 9 years old (delayed nesters). During their first reproductive effort, young nesters and delayed nesters produced similar-sized …
