    Within the field of public relations, professionals utilize case study methodology to research efficient public relations tactics and strategies. Specifically, a public relations case study is an-depth qualitative analysis of a particular public relations campaign performed by an organization, providing a vital tool for public relations scholars to study complex phenomena within their contexts (Baxter, 2008, p. 2). This particular case study will be examining public relations in a deeper sense than the traditional view of public relations merely serving as a relationship management role within an organization. Instead, public relations activism as a demonstration of the postmodernist worldview will be explored through descriptive case methodology. Public relations in the activist function can support the oppressed against the dominant coalition (Benecke and Oksiutycz, 2006, p. 817). Perhaps one of the most successful examples of PR activism in recent history began on April 30, 2015 on the grounds of the U.S. Capitol, when a 74-year-old Independent Vermont senator announced his candidacy for the presidency of the United States of America. What began as a dark horse campaign with little support morphed into the epitome of postmodern public relations – fundamental change and addressing societal problems became the heart of the Sanders’ movement (Holtzhausen, 2000, p. 99). Many of the millennial generation, including first time voters in particular, gravitated toward such a mindset, sparking the beginning of what has been called a political revolution within America. By researching the public relations tactics and techniques utilized by the volunteers in favor of Senator Sanders, the researcher explores how community dialogue through the mobile movement is tied to societal and cultural changes. Using the postmodern public relations perspective, viral communication can be used more effectively and perhaps used to inspire an entire generation

    The millennial generation is now completely immersed in today’s work force. With job satisfaction playing a large role in whether an individual chooses to stay in a job role and make it a career or move on to the next opportunity out there. Health and wellness in the work life atmosphere pertaining to physical, mental, and emotional well-being could be a contributing factor in what makes the people of a millennial generation choose between different opportunities. The quality of a person’s life and health are becoming the main priority and the focus on whether the company is looking to better each individual is a key in the selection process. Exploring the connection and comparison between these dynamics is something that could explore what comes next for big businesses and what young working individuals are working for. Some important public health disorders that obesity contributes to are cardiovascular disease, diabetes mellitus, gallbladder disease, psychosocial disability, and musculoskeletal disorders. Other conditions linked with obesity include renal disease, liver disorders, ventilator defects, venous stasis and thromboembolisms, gout, cerebrovascular disease, and (in women) endometrial and possible breast cancer. Overweight and obese people are open to higher risks from surgery, anesthesia, and accidents, and they have a high rate of employee absenteeism and statistics regarding body weight and longevity are examined, (Van Itallie, 2013). Millennials are becoming more aware of these health issues and are trying to work towards a brighter and healthier future. A retirement plan and medical benefits are standard practice, and people now look for additional health benefits such as gym memberships and paid time off for mental health. A new way of work is here to stay and the work industry as a whole is doing WELL-BEING CORRELATIONS TO JOB SATISFACTION 4 everything in its power to stay competitive when it comes to what benefits they can offer their employees to edge out other companies

    Spottail shiner (Notropis hudsonius) and delta smelt (Hypomesus transpacificus) were introduced into Willard Reservoir to improve the forage base for walleye (Stizostedion vitreum vitreum) and black crappie (Pomoxis nigromaculatus). Spottail shiners were stocked in early spring in 1981, 1982, and 1983. Hauling mortality was generally great and an estimated 34,500 live fish were stocked in the 3-year period. Spottail shiner reproduction occurred each year of stocking. Delta smelt were introduced in 1982 with the stocking of 15,000 adult spawning fish. Stocking survival was estimated at 99%. Freshly spawned eggs were also obtained and placed in a tributary to Willard Reservoir. Shoreline seining produced 29 · young-of-the-year delta smelt during June 1982. Growth of the captured young-of-the-year spottail shiner and delta smelt in Willard Reservoir compared favorably with growth found in their respective native waters. Stomach analysis indicated food habits were similar to those in native waters. Food habit analysis of young-of-the-year walleye, black crappie, spottail shiner, and delta smelt indicated very little overlap of food organisms between the four fish species. Spottail shiners occurred in 3 of 56 walleye stomachs containing food items in 1982 and 3 of 41 stomachs containing food items in 1983. Delta smelt were not found in the 132 walleye stomachs examined. However, six adult delta smelt were angler-caught walleye in April 1983. No found in the stomachs of spottail shiners or delta smelt were found in 79 black crappie stomachs examined in 1982 or 62 stomachs examined in 1983. Low utilization of spottail shiner and delta smelt was attributed to the low relative abundance of the two species in Willard Reservoir

    Many marine invertebrates bud vegetatively to produce a modular colony of individuals derived from a single zygote. Fusion of different colonies to produce a genetically composite entity (a chimera) is known from experiements on sponges, hydroids, corals, bryozoans and ascidians-groups which together dominate sessile faunas on marine hard substrates. In this study the fusion behaviour of the colonial ascidian Diplosoma literianum (Milne Edwards) has been investigate. Laboratory experiments were undertaken to assess the influence of relatedness on fusion behaviour in young and adult colonies. The degree of relatedness had a slight effect on the fusion behaviour; nevertheless unrelated colonies fused with a frequency of 15%. These fusion trials were conducted using colonies from the same population and form geographically distant populations. In addition chimeric associations between unrelated colonies were shown to remain stable for over 15 months. The presence and extent of chimerism in natural habitats was investigated applying random amplified polymorphic DNA (RAPD) analysis to individual modules (zooids) dissected from colonies from eight different wild populations. Chimerism was detached in all populations, with varying frequency of up to 61%. Field experiments were designed to test for fitness consequence of fusion in young colonies. Overall, there was no significant difference between fused and unfused treatments regarding the growth of the colonies or the onset of sexual maturation. Finally, the mechanism of fusion was studied in a number of different approaches including the development of a tissue culture protocol for tunic tissue explants. Cells of different genetic origin showed no specific reaction to each other, but intermingle freely both in vivo (in the tunic of chimeras) and in vitro. To evaluate the biological significance of fusion, studies on other species described in the literature were taken into account and discussed with the findings of this work

    A 14 wk lactation trial was conducted to evaluate the feeding value of brown-midrib (bm3) corn silage and its normal (N) genetic counterpart using ten Holstein cows per group averaging 6 wk post-partum at the start of the experiment. The cow were fed corn silage (bm3 or N) ad libitum, 2.25 kg alfalfa hay/hd and grain (1 kg/3 kg milk produced) dairy. The bm3 and N, respectively. Milk production for cows fed bm3 and N was 25.0 and 25.5 kg/day. Fat corrected milk and solids corrected milk were similar for both groups. A total collection digestion trial was conducted with six cows from each group at the end of the laction trial. Digestibilities for bm3 and N ration were, respectively: dry matter, 62.9% and 59.5%; cell wall constituents, 60.1% and 50.5%; lignin, 50.9% and 44.3%; cellulose, 59.9% and 53.2%; hemicellulose, 66.5% and 62.8; and energy, 62.4% and 59.0%. There was no difference in nitrogen utilization for the two silage rations. Rumen sample were taken via the stomach tube at 0, 3, 6, 9 and 12 hr post-feeding the last day of the digestion trial. Concentrations of total volatile fatty acids (59.8 and 66.7 moles/ml for bm3 and N) and butyrate (9.7 and 11.9 moles/ml) were greater for the N fed cows. Rumen pH was lower for N, while rumen ammonia was similar for both groups. Analysis of blood samples taken at the time of rumen sampling from the jugular vein showed that blood glucose and urea nitrogen concentrations were similar for both groups

    In vitro experiments were conducted to determine the extent of vitamins D(,2) and D(,3) degradation by rumen microbes. After 24 h of incubating (\u273)H-vitamins D(,2) and D(,3) in rumen fluid, 10 to 25% of the added label remained as vitamims D(,2) and D(,3). Both vitamins D(,2) and D(,3) yielded three major radioactive chromatographic peaks (tabbed Q, R(,1), and R(,2)) that were more polar than the parent vitamins D(,2) and D(,3). Peak Q, the major metabolite of vitamins D(,2) and D(,3), was chosen for further characterization. Peak Q was resolved into two peaks by high-performance liquid chromatography (HPLC) (tabbed Q(,1) and Q(,2)). Ultraviolet spectra showed a (lamda)max for Q(,1) of 308 nm, a (lamda)max for Q(,2) of 310 nm, with both Q metabolites having a (lamda)min of 250 nm. Further, both Q(,1) and Q(,2) were isolated from rumen fluid of calves orally administered (\u273)H-vitamin D(,2) or D(,3). Only Q(,2) could be isolated from plasma taken from (\u273)H-vitamin D-treated claves. When tested in vivo, neither Q(,1) nor Q(,2) had bone mineral resorbing activity.;The concentrations of vitamin D(,2), vitamin D(,3), and their metabolites in plasma were determined after a single oral dose of (\u273)H-vitamin D(,2) or D(,3) to each of six, 95-105 kg, Jersey bull calves (3 calves/group). Over a period of 3 wk after the oral doses, 14 blood samples were taken from each calf. Total plasma radioactivity peaked at 80 h in both groups (8400 dpm/ml and 4600 dpm/ml in the (\u273)H-vitamin D(,3)- and (\u273)H-vitamin D(,2)-treated calves, respectively). In both groups, vitamin D radioactivity peaked at 24 to 48 h and was the predominant form of (\u273)H-vitamin D in plasma 10 to 15 h after dosing. After 15 h, (\u273)H-25-hydroxyvitamin D ((\u273)H-25-OH-D) became the predominant labelled metabolite, reaching its maximal concentration between 48 and 96 h. The appearance of (\u273)H-25,26-dihydroxyvitamin D ((\u273)H-25,26-(OH)(,2)-D) and (\u273)H-1,25 dihydroxyvitamin D ((\u273)H-1,25-(OH)(,2)-D) paralleled the appearance of (\u273)H-25-OH-D. The amount of (\u273)H-25,26-(OH)(,2)-D and (\u273)H-1,25-(OH)(,2)-D arising from (\u273)H-vitamin D(,2) was 10- to 15-fold less than the amount of these metabolites from (\u273)H-vitamin D(,3). (\u273)H-24,25-Dihydroxyvitamin D steadily increased in the plasma and attained a maximum at 300 to 400 h. In addition to the known vitamin D metabolites, four unidentified (\u273)H-vitamin D metabolites appeared in the plasma and reached maximal concentrations at 48 to 72 h

    Active minimization of energy density in three-dimensional enclosures

    Get PDF
    The objective of this research project is to further investigate and develop a novel approach for actively controlling the sound field in enclosures. Typically the acoustic field in an enclosure has been controlled by minimizing the sum of the squared pressures from several microphones distributed throughout the enclosure. The approach being investigated in this project involves minimizing the acoustic energy density at the sensor locations, rather than the squared pressure. Previous research in a simple one-dimensional enclosure showed that improved global attenuation of the acoustic field is often obtained by minimizing the energy density, rather than the pressure. The current project builds on the previous research by extending the method of controlling the acoustic energy density to three-dimensional enclosures. The results will establish if improved control can still be expected in a more general enclosure. Pending successful results, the method could be applied to control problems such as attenuating the acoustic noise in an aircraft fuselage, an automobile cabin, or other general enclosures. The research project was set up as a two-year project designed to achieve both numerical and experimental results. The primary focus of the first year of research (now being completed) was on the analytical/numerical modeling of the method of controlling the acoustic energy density. During the second year, the research focuses on experimental verification of the approach and extending our understanding of the method

    Can grid-tied solar photovoltaics lead to residential heating electrification? A techno-economic case study in the midwestern U.S.

    Get PDF
    This study aims to quantify the techno-economic potential of using solar photovoltaics (PV) to support heat pumps (HP) towards the replacement of natural gas heating in a representative North American residence from a house owner\u27s point of view. For this purpose, simulations are performed on: (1) a residential natural gas-based heating system and grid electricity, (2) a residential natural gas-based heating system with PV to serve the electric load, (3) a residential HP system with grid electricity, and (4) a residential HP+PV system. Detailed descriptions are provided along with a comprehensive sensitivity analysis for identifying specific boundary conditions that enable lower total life cycle cost. The results show that under typical inflation conditions, the lifecycle cost of natural gas and reversable, air-source heat pumps are nearly identical, however the electricity rate structure makes PV costlier. With higher rates of inflation or lower PV capital costs, PV becomes a hedge against rising prices and encourages the adoption of HPs by also locking in both electricity and heating cost growth. The real internal rate of return for such prosumer technologies is 20x greater than a long-term certificate of deposit, which demonstrates the additional value PV and HP technologies offer prosumers over comparably secure investment vehicles while making substantive reductions in carbon emissions. Using the large volume of results generated, impacts on energy policy are discussed, including rebates, net-metering, and utility business models
