Research into the preparedness of Company XYZ for the implementation of the proposed OSHA ergonomic standard
No full textPlan BOSHA is proposing an ergonomic standard to help employers address ergonomic hazards in the workplace. Ergonomics is currently, covered under the general duty clause, which stipulates that employers must provide a safe workplace free from recognized hazards. The purpose of this study was to measure the preparedness of Company XYZ for the implementation of the new proposed standard. The significance of this study is that Musculoskeletal Disorders account for one third of the occupational injuries reported to the Bureau of Labor Statistics. OSHA estimated that ergonomic programs that were developed in house already protect over 50 percent of all employees and 28 percent of the work place in general industry. In this study, Company XYZ had some of the major components of the ergonomic program currently in place. A lot of the current policies were not recognized as potential ergonomical interventions to the operators and/or management. Company XYZ has several job functions that must be addressed before this standard can be fully implemented. These job functions will pose the greatest impact to the company as far as ergonomics is concerned. This company will need to educate the employees with the impact of ergonomics to the workforce in order to reach full compliance with the standard

Invasion strategies in clonal aquatic plants: Are phenotypic differences caused by phenotypic plasticity or local adaptation?
No full textBackground and Aims: The successful spread of invasive plants in new environments is often linked to multiple introductions and a diverse gene pool that facilitates local adaptation to variable environmental conditions. For clonal plants, however, phenotypic plasticity may be equally important. Here the primary adaptive strategy in three non-native, clonally reproducing macrophytes (Egeria densa, Elodea canadensis and Lagarosiphon major) in New Zealand freshwaters were examined and an attempt was made to link observed differences in plant morphology to local variation in habitat conditions. Methods: Field populations with a large phenotypic variety were sampled in a range of lakes and streams with different chemical and physical properties. The phenotypic plasticity of the species before and after cultivation was studied in a common garden growth experiment, and the genetic diversity of these same populations was also quantified. Key Results: For all three species, greater variation in plant characteristics was found before they were grown in standardized conditions. Moreover, field populations displayed remarkably little genetic variation and there was little interaction between habitat conditions and plant morphological characteristics. Conclusions: The results indicate that at the current stage of spread into New Zealand, the primary adaptive strategy of these three invasive macrophytes is phenotypic plasticity. However, while limited, the possibility that genetic diversity between populations may facilitate ecotypic differentiation in the future cannot be excluded. These results thus indicate that invasive clonal aquatic plants adapt to new introduced areas by phenotypic plasticity. Inorganic carbon, nitrogen and phosphorous were important in controlling plant size of E. canadensis and L. major, but no other relationships between plant characteristics and habitat conditions were apparent. This implies that within-species differences in plant size can be explained by local nutrient conditions. All together this strongly suggests that invasive clonal aquatic plants adapt to a wide range of habitats in introduced areas by phenotypic plasticity rather than local adaptation. © 2010 The Author.

Exploring the borders of European Phragmites within a cosmopolitan genus
No full textBackground and aims Two Phragmites australis taxa are recognized in Europe: P. australis ssp. altissimus, also known as Phragmites isiaca, in the Mediterranean region and P. australis in the temperate region. Another taxonomic group in the Mediterranean is Phragmites frutescens. European genotypes are diverse genetically, cytologically and morphologically, and are related to African, Asiatic and American genotypes. We investigated chloroplast DNA (cpDNA) diversity in Europe and defined the current borders of the European gene pool. Methodology We analysed chloroplast variation with parsimony and genetic distance methods, and compared it with that of nuclear amplified fragment length polymorphism and microsatellites. We also investigated the phenological pattern of 188 genotypes collected worldwide in a common garden in Denmark. We assumed that non-flowering genotypes could indicate climatic, geographic and/or reproductive barriers to dispersal and would have been recorded in the genetic pattern as groups genetically isolated from, or within, the European pool. Principal results The European P. australis gene pool extends from North America to the Far East and South Africa. However, African and North American genotypes are differentiating from the European genotypes. Mediterranean P. australis is genetically different from temperate P. australis and shares several similarities with Phragmites mauritianus in Africa and Phragmites karka in Asia. Phragmites frutescens shares the cpDNA sequences with both these tropical species. Two DNA bands can distinguish Mediterranean P. australis from P. frutescens and P. mauritianus and from temperate P. australis, and reveal possible hybrids among these species in the Mediterranean region. Phenological data confirmed possible gene flow within the temperate region of Europe, whereas the Mediterranean genotypes did not set inflorescences in Denmark, suggesting reproductive barriers between temperate and Mediterranean P. australis. Conclusions European P. australis appears as one of four main Phragmites groups known in the world. Further research is needed to understand the implications of long-distance dispersal at the population level
Does Rejecting an LGB identity label negatively effect mental health? A study of same-sex attracted Mormon adults
No full textPresentation by Grace Kappers ('19), Sydney Sorrell ('19), and Ashley Plunk ('19) delivered at the Rhodes College Undergraduate Research and Creative Activity Symposium (URCAS).In the Church of Jesus Christ of Latter-Day Saints (LDS), beliefs about same sex sexual
attraction are carefully differentiated from beliefs about same sex sexual behavior and LGB
identity labels. In the LDS church, same-sex attraction is accepted, but same sex behavior and
LGB identity labels are viewed as sinful (Church of Jesus Christ of Latter-Day Saints 2007).
This conflict between religious and sexual identities can complicate sexual identity development
for individuals who experience same-sex attraction, and lead some same-sex attracted individuals
to reject an LGB identity label (Label Rejecters). The present study uses data from the Four
Options survey to examine the relationship between rejecting an LGB identity label and mental
health outcomes in a sample of same-sex attracted Mormon adults. Although Label Rejecters
were significantly more religious than LGB individuals, the two groups did not differ on
resolution between religious and sexual identities. Furthermore, Label Rejecters demonstrated
significantly higher levels of internalized homonegativity. The results of this study will increase
our understanding of the effects of rejecting an LGB identity label on well being, while also
expanding our knowledge of minority sexual identity development in LDS individuals

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
