The North Carolina Symphony: a case study in fiscal sustainability strategies for a large American orchestra
The purpose of this document is to identify fiscal sustainability strategies that have been successfully employed by a large American symphony orchestra and to provide concrete suggestions for orchestra managers seeking to improve their orchestrasâ fiscal sustainability. To accomplish this purpose, this document addresses the following questions: 1. Which large American symphony orchestras are fiscally consistent? 2. What are the factors that contribute to a large American orchestraâs fiscal consistency and fiscal sustainability? 3. How can practitioners incorporate these practices into their own orchestras? To answer the first research question, the 2005â2011 tax-form 990s of 25 large American orchestras were surveyed. Total Income/Total Expense ratios were calculated for each orchestra, and five orchestras consistently achieved an income ratio of over 100% from 2005 to 2011. The five orchestras included the Los Angeles Philharmonic, St. Louis Symphony, Cincinnati Symphony, North Carolina Symphony, and Buffalo Philharmonic. To answer the second research question, one of the five orchestras was selected as the subject for a qualitative single-case study to determine what factors contributed to its fiscal consistency from 2005 to 2011. While any of the orchestras might have been chosen as the case study subject, the North Carolina Symphony was selected due to the fact that it displayed high levels of government support that were disproportional to sector norms. Analysis from the case study indicated that while government funding was a crucial income source for the North Carolina Symphony, the orchestraâs fiscal sustainability was primarily derived from community engagement, fostered by the North Carolina Symphonyâs clarity of mission that translated into community-oriented program activities. Secondary fiscal sustainability strategies included transparency, leveraging human resources, and a service mindset.To answer the third research question, the last section of the document contains practical suggestions derived from the case study analysis to be employed by orchestra practitioners who seek to improve their organizationsâ fiscal sustainability
The choreography, production and notation of "The covetous sister"
A. Statement of the Problem It was the problem of this study (l) to choreograph a long dance in which there were solo, duet, trio, and group dances for women; (2) to produce the dance with proper costumes, stage sets, lights, and music; (3) to notate the dance production by means of photography. B. Purpose of the Study The main objectives of this study were (1) to gain experience in choreography; (2) to study and correlate the contributing arts and production techniques; (3) to communicate the idea that a sister's greed for material things and her jealousy for the possessions of others cannot be solved by court decisions
Gene-environment interactions and obesity traits among postmenopausal African-American and Hispanic women in the Womenâs Health Initiative SHARe Study
Genome-wide association studies of obesity measures have identified associations with single nucleotide polymorphisms (SNPs). However, no large-scale evaluation of gene-environment interactions has been performed. We conducted a search of gene-environment (GĂE) interactions in post-menopausal African-American and Hispanic women from the Womenâs Health Initiative SNP Health Association Resource GWAS study. Single SNP linear regression on body mass index (BMI) and waist-to-hip circumference ratio (WHR) adjusted for multidimensional-scaling-derived axes of ancestry and age was run in race-stratified data with 871,512 SNPs available from African-Americans (N=8,203) and 786,776 SNPs from Hispanics (N=3,484). Tests of GĂE interaction at all SNPs for recreational physical activity (met-hrs/wk), dietary energy intake (kcal/day), alcohol intake (categorical), cigarette smoking years, and cigarette smoking (ever vs. never) were run in African-Americans and Hispanics adjusted for ancestry and age at interview, followed by meta-analysis of GĂE interaction terms. The strongest evidence for concordant GĂE interactions in African-Americans and Hispanics was for smoking and marker rs10133840 (Q statistic P=0.70, beta=â0.01, P=3.81Ă10â7) with BMI as the outcome. The strongest evidence for GĂE interaction within a cohort was in African-Americans with WHR as outcome for dietary energy intake and rs9557704 (SNPĂkcal =â0.04, P=2.17Ă10â7). No results exceeded the Bonferroniâcorrected statistical significance threshold
Hematopoietic Stem Cell Development Is Dependent on Blood Flow
SummaryDuring vertebrate embryogenesis, hematopoietic stem cells (HSCs) arise in the aorta-gonads-mesonephros (AGM) region. We report here that blood flow is a conserved regulator of HSC formation. In zebrafish, chemical blood flow modulators regulated HSC development, and silent heart (sih) embryos, lacking a heartbeat and blood circulation, exhibited severely reduced HSCs. Flow-modifying compounds primarily affected HSC induction after the onset of heartbeat; however, nitric oxide (NO) donors regulated HSC number even when treatment occurred before the initiation of circulation, and rescued HSCs in sih mutants. Morpholino knockdown of nos1 (nnos/enos) blocked HSC development, and its requirement was shown to be cell autonomous. In the mouse, Nos3 (eNos) was expressed in HSCs in the AGM. Intrauterine Nos inhibition or embryonic Nos3 deficiency resulted in a reduction of hematopoietic clusters and transplantable murine HSCs. This work links blood flow to AGM hematopoiesis and identifies NO as a conserved downstream regulator of HSC development
Candidate genetic analysis of plasma high-density lipoprotein-cholesterol and severity of coronary atherosclerosis
<p>Abstract</p> <p>Background</p> <p>Plasma level of high-density lipoprotein-cholesterol (HDL-C), a heritable trait, is an important determinant of susceptibility to atherosclerosis. Non-synonymous and regulatory single nucleotide polymorphisms (SNPs) in genes implicated in HDL-C synthesis and metabolism are likely to influence plasma HDL-C, apolipoprotein A-I (apo A-I) levels and severity of coronary atherosclerosis.</p> <p>Methods</p> <p>We genotyped 784 unrelated Caucasian individuals from two sets of populations (Lipoprotein and Coronary Atherosclerosis Study- LCAS, N = 333 and TexGen, N = 451) for 94 SNPs in 42 candidate genes by 5' nuclease assays. We tested the distribution of the phenotypes by the Shapiro-Wilk normality test. We used Box-Cox regression to analyze associations of the non-normally distributed phenotypes (plasma HDL-C and apo A-I levels) with the genotypes. We included sex, age, body mass index (BMI), diabetes mellitus (DM), and cigarette smoking as covariates. We calculated the q values as indicators of the false positive discovery rate (FDR).</p> <p>Results</p> <p>Plasma HDL-C levels were associated with sex (higher in females), BMI (inversely), smoking (lower in smokers), DM (lower in those with DM) and SNPs in <it>APOA5, APOC2</it>, <it>CETP, LPL </it>and <it>LIPC </it>(each q â€0.01). Likewise, plasma apo A-I levels, available in the LCAS subset, were associated with SNPs in <it>CETP</it>, <it>APOA5</it>, and <it>APOC2 </it>as well as with BMI, sex and age (all q values â€0.03). The <it>APOA5 </it>variant S19W was also associated with minimal lumen diameter (MLD) of coronary atherosclerotic lesions, a quantitative index of severity of coronary atherosclerosis (q = 0.018); mean number of coronary artery occlusions (p = 0.034) at the baseline and progression of coronary atherosclerosis, as indicated by the loss of MLD.</p> <p>Conclusion</p> <p>Putatively functional variants of <it>APOA2</it>, <it>APOA5, APOC2</it>, <it>CETP, LPL</it>, <it>LIPC </it>and <it>SOAT2 </it>are independent genetic determinants of plasma HDL-C levels. The non-synonymous S19W SNP in <it>APOA5 </it>is also an independent determinant of plasma apo A-I level, severity of coronary atherosclerosis and its progression.</p

Genome-Wide Association of Body Fat Distribution in African Ancestry Populations Suggests New Loci
Central obesity, measured by waist circumference (WC) or waist-hip ratio (WHR), is a marker of body fat distribution. Although obesity disproportionately affects minority populations, few studies have conducted genome-wide association study (GWAS) of fat distribution among those of predominantly African ancestry (AA). We performed GWAS of WC and WHR, adjusted and unadjusted for BMI, in up to 33,591 and 27,350 AA individuals, respectively. We identified loci associated with fat distribution in AA individuals using meta-analyses of GWA results for WC and WHR (stage 1). Overall, 25 SNPs with single genomic control (GC)-corrected p-values<5.0Ă10â6 were followed-up (stage 2) in AA with WC and with WHR. Additionally, we interrogated genomic regions of previously identified European ancestry (EA) WHR loci among AA. In joint analysis of association results including both Stage 1 and 2 cohorts, 2 SNPs demonstrated association, rs2075064 at LHX2, pâ=â2.24Ă10â8 for WC-adjusted-for-BMI, and rs6931262 at RREB1, pâ=â2.48Ă10â8 for WHR-adjusted-for-BMI. However, neither signal was genome-wide significant after double GC-correction (LHX2: pâ=â6.5Ă10â8; RREB1: pâ=â5.7Ă10â8). Six of fourteen previously reported loci for waist in EA populations were significant (p<0.05 divided by the number of independent SNPs within the region) in AA studied here (TBX15-WARS2, GRB14, ADAMTS9, LY86, RSPO3, ITPR2-SSPN). Further, we observed associations with metabolic traits: rs13389219 at GRB14 associated with HDL-cholesterol, triglycerides, and fasting insulin, and rs13060013 at ADAMTS9 with HDL-cholesterol and fasting insulin. Finally, we observed nominal evidence for sexual dimorphism, with stronger results in AA women at the GRB14 locus (p for interactionâ=â0.02). In conclusion, we identified two suggestive loci associated with fat distribution in AA populations in addition to confirming 6 loci previously identified in populations of EA. These findings reinforce the concept that there are fat distribution loci that are independent of generalized adiposity

The trans-ancestral genomic architecture of glycemic traits
Glycemic traits are used to diagnose and monitor type 2 diabetes and cardiometabolic health. To date, most genetic studies of glycemic traits have focused on individuals of European ancestry. Here we aggregated genome-wide association studies comprising up to 281,416 individuals without diabetes (30% non-European ancestry) for whom fasting glucose, 2-h glucose after an oral glucose challenge, glycated hemoglobin and fasting insulin data were available. Trans-ancestry and single-ancestry meta-analyses identified 242 loci (99 novel; P < 5 x 10(-8)), 80% of which had no significant evidence of between-ancestry heterogeneity. Analyses restricted to individuals of European ancestry with equivalent sample size would have led to 24 fewer new loci. Compared with single-ancestry analyses, equivalent-sized trans-ancestry fine-mapping reduced the number of estimated variants in 99% credible sets by a median of 37.5%. Genomic-feature, gene-expression and gene-set analyses revealed distinct biological signatures for each trait, highlighting different underlying biological pathways. Our results increase our understanding of diabetes pathophysiology by using trans-ancestry studies for improved power and resolution. A trans-ancestry meta-analysis of GWAS of glycemic traits in up to 281,416 individuals identifies 99 novel loci, of which one quarter was found due to the multi-ancestry approach, which also improves fine-mapping of credible variant sets.Peer reviewe
