Isamu Noguchi\u27s Modernism: Negotiating Race, Labor, and Nation, 1930-1950

In a study that combines archival research, a firm grounding in the historical context, biographical analysis, and sustained attention to specific works of art, Amy Lyford provides an account of Isamu Noguchi\u27s work between 1930 and 1950 and situates him among other artists who found it necessary to negotiate the issues of race and national identity. In particular, Lyford explores Noguchi\u27s sense of his art as a form of social activism and a means of struggling against stereotypes of race, ethnicity, and national identity. Ultimately, the aesthetics and rhetoric of American modernism in this period both energized Noguchi\u27s artistic production and constrained his public reputation

The 2008 US Presidential Election and New Digital Technologies: Political Campaigns as Social Movements and the Significance of Collective Identity

The growing role of the Internet social networking sites (SNS) has served as a flash point for debate about the democratization of information, particularly in light of their perceived roles in the 2008 presidential election. This horizontal sharing of information undoubtedly facilitated the revival of the youth vote and volunteerism in many ways mimicking traditional grassroots approaches. While the role of the Internet SNS in mobilization efforts and information-sharing cannot be overstated, its effectiveness in creating a new “public sphere,” or transforming traditional electoral campaign strategies and communicative practices must be closely examined before generalizations about the democratization of media can be confirmed. In the aftermath of the election, theorists were quick to simplistically identify the use of social networking sites as key to this electoral shift. In this paper we attempt to advance contemporary theorizing of new media and institutional politics by examining specifically how and if ICTs (information communication technologies) and new media platforms are shifting the balance of power in terms of organization and mobilization away from the professional model and toward more democratic and bottom-up efforts. Reconceptualizing some of the basic theories of social movements and collective behavior this paper seeks to address questions such as: how are digitally enabled forms of mobilization affecting who becomes a participant; how do they affect organizational structure and leadership; how do they impact the dynamics of collective action; how do we address the powerful yet ephemeral effect of e-tactics established for short-term gains; can mobilizations succeed without collective identity and/or do we need new categorizations for collective identity; and whether e-tactics serve as a gateway for future participation

Chapman Faculty Perceptions of Hiring Practices to Increase Racial & Ethnic Diversity

Historically, universities have been institutions primarily consisting of White males. While there have been significant improvements in racially and ethnically diversifying undergraduate student populations, faculty demographics have been slower to change. Researchers pose several explanations for this occurrence, including low numbers of qualified Ph.D. candidates from racially and ethnically underrepresented backgrounds as well as feelings of isolation that racial and ethnic minority faculty often face due to lack of available mentorship. This low representation of racially and ethnically underrepresented minorities is concerning as extensive research suggests that diversity among faculty appointments enhances the overall quality of a university, and, specifically, has a strong, positive impact on undergraduate education. In recognition of numerous benefits of a racially and ethnically diverse faculty body, this study draws particularly from research which suggests the hiring process is a viable mechanism through which to address the lack of racial and ethnic diversity. Taking into consideration various resource guides that esteemed other universities have created detailing suggested best hiring practices, we created a survey that includes a variety of hiring strategies and invited Chapman faculty and/or individuals who served on search committees at Chapman University to complete it. Participants were given short, open-ended questions in addition to statements which they were asked to rate. The survey encompassed several aspects of the hiring process including preparing the search, writing the job description, recruiting candidates, interviewing, evaluating candidates, as well as retention and inclusion strategies. The results of this study lend themselves to offering empirically based recommendations that can be utilized and potentially implemented at Chapman University to increase the likelihood of racially and ethnically diversifying faculty demographics

The association of HFE gene H63D polymorphism with endurance athlete status and aerobic capacity: novel findings and a meta-analysis.

PURPOSE: Iron is an important component of the oxygen-binding proteins and may be critical to optimal athletic performance. Previous studies have suggested that the G allele of C/G rare variant (rs1799945), which causes H63D amino acid replacement, in the HFE is associated with elevated iron indexes and may give some advantage in endurance-oriented sports. The aim of the present study was to investigate the association between the HFE H63D polymorphism and elite endurance athlete status in Japanese and Russian populations, aerobic capacity and to perform a meta-analysis using current findings and three previous studies. METHODS: The study involved 315 international-level endurance athletes (255 Russian and 60 Japanese) and 809 healthy controls (405 Russian and 404 Japanese). Genotyping was performed using micro-array analysis or by PCR. VO2max in 46 male Russian endurance athletes was determined using gas analysis system. RESULTS: The frequency of the iron-increasing CG/GG genotypes was significantly higher in Russian (38.0 vs 24.9%; OR 1.85, P = 0.0003) and Japanese (13.3 vs 5.0%; OR 2.95, P = 0.011) endurance athletes compared to ethnically matched controls. The meta-analysis using five cohorts (two French, Japanese, Spanish, and Russian; 586 athletes and 1416 controls) showed significant prevalence of the CG/GG genotypes in endurance athletes compared to controls (OR 1.96, 95% CI 1.58-2.45; P = 1.7 × 10-9). Furthermore, the HFE G allele was associated with high V̇O2max in male athletes [CC: 61.8 (6.1), CG/GG: 66.3 (7.8) ml/min/kg; P = 0.036]. CONCLUSIONS: We have shown that the HFE H63D polymorphism is strongly associated with elite endurance athlete status, regardless ethnicities and aerobic capacity in Russian athletes

Genome-Wide Association Study Reveals a Novel Association Between MYBPC3 Gene Polymorphism, Endurance Athlete Status, Aerobic Capacity and Steroid Metabolism.

The genetic predisposition to elite athletic performance has been a controversial subject due to the underpowered studies and the small effect size of identified genetic variants. The aims of this study were to investigate the association of common single-nucleotide polymorphisms (SNPs) with endurance athlete status in a large cohort of elite European athletes using GWAS approach, followed by replication studies in Russian and Japanese elite athletes and functional validation using metabolomics analysis. The association of 476,728 SNPs of Illumina DrugCore Gene chip and endurance athlete status was investigated in 796 European international-level athletes (645 males, 151 females) by comparing allelic frequencies between athletes specialized in sports with high ( = 662) and low/moderate ( = 134) aerobic component. Replication of results was performed by comparing the frequencies of the most significant SNPs between 242 and 168 elite Russian high and low/moderate aerobic athletes, respectively, and between 60 elite Japanese endurance athletes and 406 controls. A meta-analysis has identified rs1052373 (GG homozygotes) in Myosin Binding Protein (; implicated in cardiac hypertrophic myopathy) gene to be associated with endurance athlete status ( = 1.43 × 10, odd ratio 2.2). Homozygotes carriers of rs1052373 G allele in Russian athletes had significantly greater VO than carriers of the AA + AG ( = 0.005). Subsequent metabolomics analysis revealed several amino acids and lipids associated with rs1052373 G allele (1.82 × 10) including the testosterone precursor androstenediol (3beta,17beta) disulfate. This is the first report of genome-wide significant SNP and related metabolites associated with elite athlete status. Further investigations of the functional relevance of the identified SNPs and metabolites in relation to enhanced athletic performance are warranted

Results: The association of 476,728 SNPs of Illumina DrugCore Gene chip and endurance athlete status was investigated in 796 European international-level athletes (645 males, 151 females) by comparing allelic frequencies between athletes specialized in sports with high (n = 662) and low/moderate (n = 134) aerobic component. Replication of results was performed by comparing the frequencies of the most significant SNPs between 242 and 168 elite Russian high and low/moderate aerobic athletes, respectively, and between 60 elite Japanese endurance athletes and 406 controls. A meta-analysis has identified rs1052373 (GG homozygotes) in Myosin Binding Protein (MYBPC3; implicated in cardiac hypertrophic myopathy) gene to be associated with endurance athlete status (P = 1.43 × 10−8, odd ratio 2.2). Homozygotes carriers of rs1052373 G allele in Russian athletes had significantly greater VO2max than carriers of the AA + AG (P = 0.005). Subsequent metabolomics analysis revealed several amino acids and lipids associated with rs1052373 G allele (1.82 × 10–05) including the testosterone precursor androstenediol (3beta,17beta) disulfate. Conclusions: This is the first report of genome-wide significant SNP and related metabolites associated with elite athlete status.

Crassulacean Acid Metabolism Photosynthesis in Pineapple (Ananas comosus (L.) Merr.) Grown under Hydroponic Culture

In order to shorten the cultivation period of pineapple, a crassulacean acid metabolism (CAM) plant, it is important to increase the rate of CO2 exchange rate and improve dry matter production, especially at the early growth stage. When plants are grown under hydroponic conditions, absorption of nutrients and plant water availability are generally increased, and in the case of CAM plants, hydroponics could be expected to improve growth rate through promoting stomatal open during daytime. The objective of this study was to examine the effect of culture method (hydroponic and soil culture) on diurnal changes in gas exchange rate and CO2 balance in pineapple. The daily CO2 balance under hydroponics tended to be higher than under soil culture, especially in Phase-4. This was due to a shortened Phase-3 and a prolonged Phase-4 under hydroponics compared to soil culture. In Phase-4, the CO2 exchange rate was significantly correlated with stomatal conductance, indicating CO2 balance was affected by stomatal activity. Rubisco consumption activated under hydroponic culture may have shortened the duration of Phase-3 when stomatal opening was suppressed. The CO2 balance tended to be increased because of the shortening of Phase-3, resulting in higher dry matter productivity. From these results, it is suggested that hydroponic culture could promote growth in pineapple. However, net assimilation rate under soil culture was equivalent to that under hydroponics. Further study is needed to reveal the relationship between hydroponic cultivation and whole-plant photosynthetic ability
