    INTRODUCTION: Introduction of solid foods before the recommended age of 4-6 months is a common practice in the United States, and appears to be especially prevalent among infants who are enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Currently, little is known about how fathers influence early infant feeding decisions, outside of the decision to breast- or formulafeed. The purpose of this study was to explore how fathers perceive the role they play in feeding and caring for their infants. METHODS: Participants were 21 male-caregivers, who were fathers or partners of the mothers of WIC income-eligible infants residing in two rural East Tennessee counties. In-depth, audio-taped telephone interviews were completed. Interviews were transcribed, coded, and analyzed according to standard grounded theory procedures to identify emergent concepts. These concepts were explored and linked together to become themes. RESULTS: Three themes emerged: 1) fathers’ roles; 2) fathers’ perceptions; 3) and control. Concepts within the theme of “fathers’ roles” included physical and emotional support for both mother and infant, validation of maternal decisions, and financial support. In this study, fathers’ perceptions were primarily shaped by their own experiences, advice from those with experience, and information sought by the fathers. The theme of control appears to be the linkage between the fathers’ attempts to modify infant behavior and infants’ responses. CONCLUSIONS: A final conceptual model was created to explain the inter-related nature of the themes and may be helpful to those who work with fathers and/or families of new infants

    Corporate Social Responsibility: the institutionalization of ESG

    Understanding the impact of Corporate Social Responsibility (CSR) on firm performance as it relates to industries reliant on technological innovation is a complex and perpetually evolving challenge. To thoroughly investigate this topic, this dissertation will adopt an economics-based structure to address three primary hypotheses. This structure allows for each hypothesis to essentially be a standalone empirical paper, unified by an overall analysis of the nature of impact that ESG has on firm performance. The first hypothesis explores the evolution of CSR to the modern quantified iteration of ESG has led to the institutionalization and standardization of the CSR concept. The second hypothesis fills gaps in existing literature testing the relationship between firm performance and ESG by finding that the relationship is significantly positive in long-term, strategic metrics (ROA and ROIC) and that there is no correlation in short-term metrics (ROE and ROS). Finally, the third hypothesis states that if a firm has a long-term strategic ESG plan, as proxied by the publication of CSR reports, then it is more resilience to damage from controversies. This is supported by the finding that pro-ESG firms consistently fared better than their counterparts in both financial and ESG performance, even in the event of a controversy. However, firms with consistent reporting are also held to a higher standard than their nonreporting peers, suggesting a higher risk and higher reward dynamic. These findings support the theory of good management, in that long-term strategic planning is both immediately economically beneficial and serves as a means of risk management and social impact mitigation. Overall, this contributes to the literature by fillings gaps in the nature of impact that ESG has on firm performance, particularly from a management perspective

    Flags, Tags, and Custom Queues

    Clemson Libraries have been using ILLiad for more than a decade. Upon recently hosting representatives from OCLC for eventual Tipasa migration, we learned that we currently use flags the way we will need to use tags in the future. As Tipasa will not offer an option for custom queues, which are a major part of our workflow, we will need to adapt tags for use in place of custom queues. This poster will outline our current plan for transforming our workflows after migration

    Nutrient limitation of periphyton growth in arctic lakes in south-west Greenland

    Many arctic lakes are oligotrophic systems where phototrophic growth is controlled by nutrient supply. Recent anthropogenic nutrient loading is associated with biological and/or physico-chemical change in several lakes across the arctic. Shifts in nutrient limitation (nitrogen (N), phosphorus (P), or N ? P) and associated effects on the growth and composition of algal communities are commonly reported. The Kangerlussuaq region of south-west Greenland forms a major lake district which is considered to receive little direct anthropogenic disturbance. However, long-range transport of pollutant N is now reaching Greenland, and it was hypothesised that a precipitation gradient from the inland ice sheet margin to the coast might also deliver increased N deposition. In situ nutrient bioassays were deployed in three lakes across the region: ice sheet margin, inland (close to Kangerlussuaq) and the coast (near Sisimiut), to determine nutrient limitation of lakes and investigate any effects of nutrients on periphyton growth and community composition. Nutrient limitation differed amongst lakes: N limitation (ice sheet margin), N and P limitation (inland) and N ? P co-limitation (coast). Factors including variation in N supply, ice phenology, seasonal algal succession, community structure and physical limnology are explored as mechanisms to explain differences amongst lakes. Nutrient limitation of arctic lakes and associated ecological impacts are highly variable, even across small geographic areas. In this highly sensitive region, future environmental change scenarios carry a strong risk of significantly altering nutrient limitation; in turn, potentially severely impacting lake structure and function

    Socs36E Controls Niche Competition by Repressing MAPK Signaling in the Drosophila Testis

    Get PDF
    The Drosophila testis is a well-established system for studying stem cell self-renewal and competition. In this tissue, the niche supports two stem cell populations, germ line stem cells (GSCs), which give rise to sperm, and somatic stem cells called cyst stem cells (CySCs), which support GSCs and their descendants. It has been established that CySCs compete with each other and with GSCs for niche access, and mutations have been identified that confer increased competitiveness to CySCs, resulting in the mutant stem cell and its descendants outcompeting wild type resident stem cells. Socs36E, which encodes a negative feedback inhibitor of the JAK/STAT pathway, was the first identified regulator of niche competition. The competitive behavior of Socs36E mutant CySCs was attributed to increased JAK/STAT signaling. Here we show that competitive behavior of Socs36E mutant CySCs is due in large part to unbridled Mitogen-Activated Protein Kinase (MAPK) signaling. In Socs36E mutant clones, MAPK activity is elevated. Furthermore, we find that clonal upregulation of MAPK in CySCs leads to their outcompetition of wild type CySCs and of GSCs, recapitulating the Socs36E mutant phenotype. Indeed, when MAPK activity is removed from Socs36E mutant clones, they lose their competitiveness but maintain self-renewal, presumably due to increased JAK/STAT signaling in these cells. Consistently, loss of JAK/STAT activity in Socs36E mutant clones severely impairs their self-renewal. Thus, our results enable the genetic separation of two essential processes that occur in stem cells. While some niche signals specify the intrinsic property of self-renewal, which is absolutely required in all stem cells for niche residence, additional signals control the ability of stem cells to compete with their neighbors. Socs36E is node through which these processes are linked, demonstrating that negative feedback inhibition integrates multiple aspects of stem cell behavior

    Freezing, pasteurizing, and drying effects on pomegranate juice flavor and acceptance

    Master of ScienceDepartment of Food ScienceKadri KoppelPomegranate fruits are seasonally produced and require processing to provide year round availability. Effects of processing on phenolic compounds, color, and other physical properties have been examined but few studies have examined the sensory effects. Juice prepared from fresh Wonderful pomegranates was used to prepare fresh frozen juice, batch pasteurized juice, and reconstituted juice from dried arils. These juices were evaluated using analytical and affective sensory methods to increase the understanding of processing effects on pomegranate juice properties. A modified consensus flavor profile showed that a large number of small differences existed. The accumulation of these changes demonstrates the distinction among processing methods. Time intensity multi-evaluation (TIME) profiling, a new method, was used to further understand how multiple attributes, including aromatics, feeling factors, and basic tastes, changed over the course of one sip. Fruity flavor was consistently the first to appear in the profile while bitterness and astringency lasted the longest. The attribute woody displayed longer peak times in the pasteurized and reconstituted samples than seen in fresh frozen juice. Semi-Continuous Consumption (SCC) profiling, another new method, explained product differences over 25 sips that mimicked consumption. Overall, astringent and bitter components increased while fruity and overall sweet attributes declined. These profile changes differed by sample with reconstituted juice showing the least increase in astringency over consumption. The juice samples were subjected to an acceptance test that showed four liking clusters, one that accepted all three juices and three clusters that disliked one of each juice type. The results from these studies are an initial step in describing how processing of pomegranate juice can effect flavor. Understanding the flavor differences is beneficial to processors for marketing products and for purchasers of these products for ingredient usage. Furthermore, the process of TIME and SCC profiling are described which are beneficial for understanding how multiple flavors change over single and multiple consumption events of a product respectively. These new methodologies are useful in explaining the experience of complex products such as teas and coffees or products exhibiting build-up such as nutrition aides
