The Coca-Cola Foundation\u27s Funds

The Coca-Cola Company is widely known to spend billions of dollars on advertising. Many of these advertising campaigns center around the company\u27s philanthropic efforts. In 2017, the Coca-Cola Foundation has helped to donate over $138 million to different organizations in order to give back to the community. I used data from this past completed year (2019) to see how much the Coca-Cola Foundation is contributing to specific causes. Using Coca Cola bottle caps, I will show the amount of money being donated to each area. Some of these areas include women\u27s empowerment, the environment, and education, which are the main focuses of the foundation

Elliptic nets and elliptic curves

An elliptic divisibility sequence is an integer recurrence sequence associated to an elliptic curve over the rationals together with a rational point on that curve. In this paper we present a higher-dimensional analogue over arbitrary base fields. Suppose E is an elliptic curve over a field K, and P_1, ..., P_n are points on E defined over K. To this information we associate an n-dimensional array of values in K satisfying a nonlinear recurrence relation. Arrays satisfying this relation are called elliptic nets. We demonstrate an explicit bijection between the set of elliptic nets and the set of elliptic curves with specified points. We also obtain Laurentness/integrality results for elliptic nets.Comment: 34 pages; several minor errors/typos corrected in v

Maintaining Credibility and Authority as an Instructor of Color in Diversity-Education Classrooms: A Qualitative Inquiry

The movement for multicultural or diversity-centered education has resulted in changes to the academic demography of the United States (Banks, 1991; Butler & Walter, 1991; Goodstein, 1994; Morey & Kitano, 1997). Institutions of higher education have integrated the voices, knowledge, and lived experiences of various underrepresented cultures and excluded groups into their formal academic curriculum. A recent survey by the American Association of Colleges and Universities (AACU) shows that 63% of colleges and universities report that they have in place, or are in the process of developing, a diversity education component in their undergraduate curriculum (AACU, 2003). Of those that have implemented dimensions of diversity into their curriculum, the majority of campuses (68%) require their students to take at least one course from among a list of approved diversity-education courses. The success of many colleges and universities at integrating this level of multicultural or diversity education into the academic curriculum marks a significant higher education milestone. However, an organized and entrenched resistance to this movement has emerged at both individual and organizational levels (Butler & Walter, 1991; Jayne, 1991). The diversity-education classroom, in particular, is a site wherein this conflict takes on particular meaning for instructors of color at all academic ranks including graduate teaching assistants and full professors (Perry, Moore, Acosta, Edwards, & Frey, 2006; Turner, 2002). Much of the existing scholarship on higher education and multicultural classrooms has focused on the impact of backlash and resistance in the general academic workplace (Yang, Barrayo, & Timpsin, 2003; Timpsin, 2003). Our current study is part of a larger investigation into the professional, emotional, and physical labor associated with teaching diversity-education courses in higher education

Investigating subtypes of reward processing deficits as trait markers for depression

Background: Anhedonia, the loss of pleasure in usually enjoyable activities, is a central feature of major depressive disorder (MDD). The aim of the present study was to examine whether young people at a familial risk of depression display signs of anticipatory, motivational or consummatory anhedonia, which would indicate that these deficits may be trait markers for MDD. Methods: The study was completed by 22 participants with a family history of depression (FH+) and 21 controls (HC). Anticipatory anhedonia was assessed by asking participants to rate their anticipated liking of pleasant and unpleasant foods which they imagined tasting when cued with images of the foods. Motivational anhedonia was measured by requiring participants to perform key presses to obtain pleasant chocolate taste rewards or to avoid unpleasant apple tastes. Additionally, physical consummatory anhedonia was examined by instructing participants to rate the pleasantness of the acquired tastes. Moreover, social consummatory anhedonia was investigated by asking participants to make preference-based choices between neutral facial expressions, genuine smiles, and polite smiles. Results: It was found that the FH+ group’s anticipated liking of unpleasant foods was significantly lower than that of the control group. By contrast, no group differences in the pleasantness ratings of the actually experienced tastes or in the amount of performed key presses were observed. However, controls preferred genuine smiles over neutral expressions more often than they preferred polite smiles over neutral expressions, while this pattern was not seen in the FH+ group. Conclusion: These findings suggest that FH+ individuals demonstrate an altered anticipatory response to negative stimuli and show signs of social consummatory anhedonia, which may be trait markers for depression

Emergence of Poplar Diseases or the “Arms Race” between Breeders and Diseases (Abstract)

Poplar cultivation is an example of highly artificialized and intensive woody plant production (clonal and evenaged cultivation) that resembles crop production more than it does forest production. Since the 19th century, breeders have created poplar varieties, especially interspecific hybrids selected on the basis of agronomic criteria (speed of growth, wood volume, straightness of stem, quality of wood). Because of the compromise between growth and resistance classically described for plants, the poplar cultivars have become a target of choice for many diseases (bacterial canker, scab, leaf blight, rust, Dothichiza, viral disease, etc.) and pests (borer, Saperda, wooly aphid, hornet moth, weevil, etc.). European poplar cultivation experienced several health crises in the 20th century that led breeders to select new varieties on the criterion of resistance to the main diseases. As a result, there were periods of massive use of certain varieties endowed with satisfactory resistance to a disease that were subsequently gradually abandoned as it became apparent that they were too susceptible to another emerging or re-emerging disease. In the particular case of poplar rust caused by the fungus Melampsora larici-populina, we have documented the existence of cycles in the use of certain varieties resistant to rust. Because the fungus is able to circumvent qualitative poplar resistance, a number of wholly resistant varieties became susceptible after just a few years of cultivation. We have shown that the implementation on a regional scale of certain poplar varieties that carry qualitative resistances had structured the M. larici-populina populations on the scale of France. In this way, the varietal distribution of poplar trees has influenced pathogen distribution. These feedback loops between host populations (poplar stands) and pathogen populations are similar to models of host/pathogen co-evolution with an “arms race” between the poplar tree (via breeders and poplar tree farmers) and the pathogens

Challenges and opportunities for agroforestry practitioners to participate in state preferential property tax programs for agriculture and forestry

All 50 states offer preferential property tax programs that lower the taxes paid on enrolled agricultural and/or forest lands. While agroforestry is a land-use that combines elements of both agriculture and forestry, eligibility criteria and other rules and regulations may prevent landowners from enrolling agroforestry practices in one or more of the agricultural and forestry tax programs. This pilot-scale study developed conceptual and methodological frameworks to identify the current barriers to and opportunities in preferential tax policies applicable to agroforestry practices. We conducted an extensive review of state preferential property tax programs relevant for agroforestry practices, following focus group discussions with regional experts in five selected states across the United States: North Carolina, Nebraska, Wisconsin, New York, and Oregon. Based on a systematic review of statutes and their supporting documents, we developed a database of programs, which support or create barriers to enrollment of agroforestry practitioners into the programs. We found that agricultural tax assessments were more likely to favor multi-use agriculture and forestry systems than the preferential tax assessments of forestlands in the five states. Forest farming and silvopasture, followed by alley cropping, windbreaks, and riparian forest buffers, were found to be the most common agroforestry practices allowed under preferential tax classifications in the study states. This study provides a framework for cataloging and analyzing preferential property tax-programs to document barriers and facilitators to agroforestry practices in the United States

Correlation Between Low Frequency Auroral Kilometric Radiation (AKR) and Auroral Structures

Auroral Kilometric Radiation (AKR) is a radio wave emission that has long been associated with auroral activity. AKR is normally observed in the frequency range from -60 - 600 kHz. Low frequency AKR (or LF-AKR) events are characterized as a rapid extension of AKR related emissions to 30 kHz or lower in frequency for typically much less than 10 minutes. LF-AKR emissions predominantly occur within a frequency range of 20 kHz - 30 kHz, but there are LF-AKR related emissions that reach to a frequency of 5 kHz. This study correlates all instances of LF-AKR events during the first four years of observations from the IMAGE spacecraft's Radio Plasma Imager (WI) instrument with auroral observations from the wideband imaging camera (WIC) onboard IMAGE. The correlation between LF-AKR occurrence and WIC auroral observations shows that in the 295 confirmed cases of LF-AKR emissions, bifurcation of the aurora is seen in 74% of the cases. The bifurcation is seen in the dusk and midnight sectors of the auroral oval, where AKR is believed to be generated. The polarization of these LF-AKR emissions has yet to be identified. Although LF-AKR may not be the only phenomena correlated with bifurcated auroral structures, bifurcation will occur in most instances when LF-AKR is observed. The LF-AKR emissions may be an indicator of specific auroral processes sometimes occurring during storm-time conditions in which field-aligned density cavities extend a distance of perhaps 5-6 RE tailward from the Earth for a period of 10 minutes or less

Substrate availability and not thermal acclimation controls microbial temperature sensitivity response to long‐term warming

Microbes are responsible for cycling carbon (C) through soils, and predicted changes in soil C stocks under climate change are highly sensitive to shifts in the mechanisms assumed to control the microbial physiological response to warming. Two mechanisms have been suggested to explain the long-term warming impact on microbial physiology: microbial thermal acclimation and changes in the quantity and quality of substrates available for microbial metabolism. Yet studies disentangling these two mechanisms are lacking. To resolve the drivers of changes in microbial physiology in response to long-term warming, we sampled soils from 13- and 28-year-old soil warming experiments in different seasons. We performed short-term laboratory incubations across a range of temperatures to measure the relationships between temperature sensitivity of physiology (growth, respiration, carbon use efficiency, and extracellular enzyme activity) and the chemical composition of soil organic matter. We observed apparent thermal acclimation of microbial respiration, but only in summer, when warming had exacerbated the seasonally-induced, already small dissolved organic matter pools. Irrespective of warming, greater quantity and quality of soil carbon increased the extracellular enzymatic pool and its temperature sensitivity. We propose that fresh litter input into the system seasonally cancels apparent thermal acclimation of C-cycling processes to decadal warming. Our findings reveal that long-term warming has indirectly affected microbial physiology via reduced C availability in this system, implying that earth system models including these negative feedbacks may be best suited to describe long-term warming effects on these soils
