D.) University of Missouri-Columbia 2006.This dissertation introduces and develops the construct of consumer cynicism, characterized by a perception of a pervasive, systemic lack of integrity in the marketplace, and investigates how cynical consumers behave in the marketplace. This dissertation developed a scale, laying groundwork for future research, and investigated cynicism antecedents, associated marketplace behaviors, and the cynicism-brand loyalty relationship. Cynical consumers perceive a marketplace full of opportunism. The nine studies reported here formed a rigorous scale development procedure. A large-scale national survey provided the final scale validation sample and primary research instrument for testing hypotheses. Consumer cynicism is shown to impact marketplace behaviors and perceptions, leading to marketplace shaping or consumer activism and criticism behaviors, marketplace withdrawal, perceptions of purchase risk, and category-specific cynicism. At the level of a particular purchase, category-specific cynicism is shown to be associated with brand support behaviors and with increased importance of trust issues, rather than satisfaction or value, in brand loyalty.Includes bibliographical reference

Virtual Advocacy: Lived Experience Takes Center Stage During and After Pandemic

COVID-19 forced a significant change for participants of the Disability Policy Seminar (DPS) typically held annually in Washington, D.C. The DPS is a policy event that both informs its participants about current policy and supports attendees visiting Capitol Hill to meet with legislators. In 2020, the DPS event, which took place during the early phase of the pandemic, was shifted from “on the Hill” to “across the screen”. Through the various lenses of an autistic self-advocate, a mother of a child with a developmental disability, and faculty of a LEND (Leadership Education in Neurodevelopmental and related Disabilities) program, this paper describes the ways in which the nature of our collaborative advocacy effort, from Hill visits to co-authorship, was shaped by changes instituted in response to COVID-19. The authors collectively explored the experience, benefit, and lasting impact of engaging in virtual advocacy from an emancipatory perspective, which highlights the voices of self-advocates and family members of people with developmental disabilities. Benefits of virtual include: 1) minimizing the physical challenges involved for persons with disabilities (particularly those with mobility issues, those who utilize durable medical equipment, and those whose disabilities make transportation challenging); 2) increasing visibility by allowing elected representatives a view into constituents’ homes; and 3) enhancing engagement for participants with different learning styles and those who communicate with support. We conclude with lessons learned within the context of a global public health emergency about how to support authentic collaboration between various stakeholders

LOCAL OBSERVERS FILL IN THE DETAILS ON DROUGHT IMPACT REPORTER MAPS

We all know that talking politics and religion in social settings-with friends, family, or strangers- can be a firestarter. By contrast, talking about the weather is a reliably safe conversational opener. But there\u27s another reason that the National Drought Mitigation Center (NDMC) wants people to talk about weather. Individuals can provide a rich source of weather-related anecdotes and observations that prove critical to evaluating droughts and enabling appropriate responses. The mechanism for this valuable conversation with the public is the Drought Impact Reporter (DIR). Lately, the NDMC has been working to refine the way this online service encourages citizen observers and incorporates information directly from them

The Missing Piece: Drought Impacts Monitoring Report from a Workshop in Tucson, AZ MARCH 5-6, 2013

Based on a shared interest to better understand the impacts of drought and the potential utility of using drought impacts reporting as a tool for monitoring conditions, researchers from the Carolinas RISA (Dow, Lackstrom, and Brennan), the Climate Assessment for the Southwest (Crimmins and Ferguson), and the Southwest Climate Science Center (Meadow) decided to convene a workshop in Tucson in March 2013. The primary goal was to assemble a small group of university and agency scientists involved with drought impacts monitoring to discuss opportunities and barriers associated with drought impacts reporting, recommend best practices for implementing a drought impacts reporting system, and develop a path forward for addressing or overcoming barriers. The longer-term objective of the initial meeting was to explore the feasibility of creating a community of practice that could share information and integrate activities related to drought impacts research and reporting

Contribution of Early-Postmortem Proteome and Metabolome to Ultimate pH and Pork Quality

This study's objectives were to identify how subtle differences in ultimate pH relate to differences in pork quality and to understand how early-postmortem glycolysis contributes to variation in ultimate pH. The hypothesis was that elements in early-postmortem longissimus thoracis et lumborum proteome and metabolome could be used to predict quality defects associated with pH decline. Temperature and pH of the longissimus thoracis et lumborum were measured at 45 min, 24 h, and 14 d postmortem. Quality measurements were made after 14 d of aging. Groups were classified as normal pH (NpH; x̄ = 5 . 59 [5.53–5.67]; NpH, n = 10) and low pH (LpH; x̄ = 5 . 42 [5.38–5.45]; LpH, n = 10) at 14 d postmortem. Metabolites from 45 min postmortem were identified using GC-MS. Relative differences between proteins were quantified with two-dimensional difference in gel electrophoreses, and spots were identified with MALDI-MS. Western blot analyses were used to measure phosphofructokinase, peroxiredoxin-2, and reduced and non-reduced adenosine monophosphate deaminase-2 at 45 min and 14 d postmortem. Ultimate pH classification did not affect 45-min-postmortem pH (P = 0.64); 14-d pH was different between groups (P < 0.01). NpH had less purge loss (P < 0.01), was darker (P < 0.01), had lower star probe (P < 0.01), and had less intact day-7 desmin (P = 0.02). More pyruvate (P = 0.01) and less lactate (P = 0.09) was observed in NpH, along with more soluble lactate dehydrogenase (P = 0.03) and pyruvate kinase (P < 0.10). These observations indicate that differences in enzyme abundance or solubility may produce more pyruvate and less lactate. Fructose 6-phosphate was more abundant (P = 0.08) in the LpH group, indicating that phosphofructokinase may be involved in glycolytic differences. Furthermore, greater abundance of heat shock proteins, peroxiredoxin-2 (P = 0.02), and malate (P = 0.01) early postmortem all suggest differences in mitochondrial function and oxidative stability that contribute to quality differences. These results show that even subtle changes in ultimate pH can influence pork quality. The proteome and metabolome at 45 min postmortem are associated with variation in the extent of pH decline

Novel Observations of Peroxiredoxin-2 Profile and Protein Oxidation in Skeletal Muscle From Pigs of Differing Residual Feed Intake and Health Status

This study’s objective was to determine the impact of a dual respiratory and enteric bacterial health challenge on the antioxidant protein peroxiredoxin-2 (Prdx-2) profile and protein oxidation in the skeletal muscle of pigs from 2 lines that were divergently selected for residual feed intake (RFI). The hypotheses were that (1) differences exist in the Prdx-2 profile between 2 RFI lines and infection status and (2) muscle from less efficient high-RFI and health-challenged pigs have greater cellular protein oxidation. Barrows (50 ± 7 kg, N = 24) from the 11th generation of the high-RFI (n = 12) and low-RFI (n = 12) Iowa State University lines were used. Pigs (n = 6 per line) were inoculated with Mycoplasma hyopneumoniae and Lawsonia intracellularis (MhLI) on day 0 post infection to induce a respiratory and enteric health challenge. Uninoculated pigs served as controls (n = 6 per line). Necropsy was at 21 d post infection. Sarcoplasmic protein oxidation, various forms of Prdx-2, and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) content were determined. Neither RFI line nor infection status significantly affected protein carbonylation. Under nonreducing conditions, MhLI pigs had a greater amount of a slower-migrating GAPDH band (P = 0.017), indicating oxidative modification. Regardless of health status, the low-RFI pigs had less total Prdx-2 (P = 0.035), Prdx-2 decamer (P = 0.0007), and a higher ratio of hyperoxidized peroxiredoxin relative to Prdx-2 (P = 0.028) than the high-RFI pigs. The increased pool of active Prdx-2 in high-RFI pigs suggests greater oxidative stress in muscle in high- versus low-RFI pigs. The increase in oxidized GAPDH seen in muscle from MhLI pigs—particularly the high-RFI MhLI pigs—may be a response to the greater oxidative stress in the high-RFI MhLI. This work suggests that antioxidant proteins are important in growth and health-challenge situations

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure
