IPCC Expert Meeting on the Science of Alternative Metrics: Meeting Report (open access)

IPCC Expert Meeting on the Science of Alternative Metrics: Meeting Report

This extended report of the IPCC Expert Meeting on the Science of Alternative Metrics that was held in Oslo 18-20 March 2009 is provided in response to an invitation from the UN Framework Convention on Climate Change Ad Hoc Working Group on Further Commitments for Annex I Parties under Kyoto Protocol (UNFCCC AWG-KP) to the Intergovernmental Panel on Climate Change (IPCC) to undertake further technical assessment of alternative common metrics which are used to calculate the CO2 equivalence of anthropogenic emissions by sources, and removals by sinks, of greenhouse gases listed in Annex A to the Kyoto Protocol. The outcome of the expert meeting was an agreed set of key conclusions and recommendations to UNFCCC in response to the request of the AWG-KP as well as more specific recommendations to the scientific community regarding research needs and ones relevant to the scoping of the IPCC's Fifth Assessment Report (AR5). These were presented to the IPCC Plenary in a short report at its 30th session in Antalya, 21-23 April 2009. The current full report of the expert meeting amplifies those conclusions and recommendations and includes the extended abstracts of the meeting presentations as well as a general bibliography.

Identifying genetic interactions of the spindle checkpoint in Caenorhabditis elegans. (open access)

Identifying genetic interactions of the spindle checkpoint in Caenorhabditis elegans.

Faithful segregation of chromosomes is ensured by the spindle checkpoint. If a kinetochore does not correctly attach to a microtubule the spindle checkpoint stops cell cycle progression until all chromosomes are attached to microtubules or tension is experienced while pulling the chromosomes. The C. elegans gene, san-1, is required for spindle checkpoint function and anoxia survival. To further understand the role of san-1 in the spindle checkpoint, an RNAi screen was conducted to identify genetic interactions with san-1. The kinetochore gene hcp-1 identified in this screen, was known to have a genetic interaction with hcp-2. Interestingly, san-1(ok1580);hcp-2(ok1757) had embryonic and larval lethal phenotypes, but the phenotypes observed are less severe compared to the phenotypes of san-1(ok1580);hcp-1(RNAi) animals. Both san-1(ok1580);hcp-1(RNAi) and san-1(ok1580);hcp-2(RNAi) produce eggs that may hatch; but san-1(ok1580):hcp-1(RNAi) larvae do not survive to adulthood due to defects caused by aberrant chromosome segregations during development. Y54G9A.6 encodes the C. elegans homolog of bub-3, and has spindle checkpoint function. In C.elegans, bub-3 has genetic interactions with san-1 and mdf-2. An RNAi screen for genetic interactions with bub-3 identified that F31F6.3 may potentially have a genetic interaction with bub-3. This work provided genetic evidence that hcp-1, hcp-2 and F31F6.2 interact with spindle checkpoint …

Cross Language Information Retrieval for Languages with Scarce Resources (open access)

Cross Language Information Retrieval for Languages with Scarce Resources

Our generation has experienced one of the most dramatic changes in how society communicates. Today, we have online information on almost any imaginable topic. However, most of this information is available in only a few dozen languages. In this thesis, I explore the use of parallel texts to enable cross-language information retrieval (CLIR) for languages with scarce resources. To build the parallel text I use the Bible. I evaluate different variables and their impact on the resulting CLIR system, specifically: (1) the CLIR results when using different amounts of parallel text; (2) the role of paraphrasing on the quality of the CLIR output; (3) the impact on accuracy when translating the query versus translating the collection of documents; and finally (4) how the results are affected by the use of different dialects. The results show that all these variables have a direct impact on the quality of the CLIR system.

Slaves and Slaveholders in the Choctaw Nation: 1830-1866 (open access)

Slaves and Slaveholders in the Choctaw Nation: 1830-1866

Racial slavery was a critical element in the cultural development of the Choctaws and was a derivative of the peculiar institution in southern states. The idea of genial and hospitable slave owners can no more be conclusively demonstrated for the Choctaws than for the antebellum South. The participation of Choctaws in the Civil War and formal alliance with the Confederacy was dominantly influenced by the slaveholding and a connection with southern identity, but was also influenced by financial concerns and an inability to remain neutral than a protection of the peculiar institution. Had the Civil War not taken place, the rate of Choctaw slave ownership possibly would have reached the level of southern states and the Choctaws would be considered part of the South.

Predicting Chemical and Biochemical Properties Using the Abraham General Solvation Model (open access)

Predicting Chemical and Biochemical Properties Using the Abraham General Solvation Model

Several studies were done to illustrate the versatillity of the Abraham model in mathematically describing the various solute-solvent interactions found in a wide range of different chemical and biological systems. The first study focused on using the solvation model to construct mathematical correlations describing the minimum inhibitory concentration of organic compounds for growth inhibition towards the three bacterial strains Porphyromonas gingivalis, Selenomonas artemidis, and Streptococcus sobrinus. The next several studies expand the practicallity of the Abraham model by predicting free energies of partition in chemical systems. The free energy studies expand the use of the Abraham model to other temperatures and properties by developing correlations for the enthalpies of solvation of gaseous solutes of various compounds dissolved in water, 1-octanol, hexane, heptane, hexadecane, cyclohexane, benzene, toluene, carbon tetrachloride, chloroform, methanol, ethanol, 1-butanol, propylene carbonate, dimethyl sulfoxide, 1,2-dichloroethane, N,N-dimethylformamide, tert-butanol, dibutyl ether, ethyl acetate, acetonitrile, and acetone. Also, a generic equation for linear alkanes is created for use when individual datasets are small. The prediction of enthalpies of solvation is furthered by modifying the Abraham model so that experimental data measured at different temperatures can be included into a single correlation expression. The temperature dependence is directly included in the model …

Grounds-Based and Grounds-Free Voluntarily Child Free Couples: Privacy Management and Reactions of Social Network Members (open access)

Grounds-Based and Grounds-Free Voluntarily Child Free Couples: Privacy Management and Reactions of Social Network Members

Voluntarily child free (VCF) individuals face stigmatization in a pronatalist society that labels those who do not want children as deviant. Because of this stigmatization, VCF couples face privacy issues as they choose to reveal or conceal their family planning decision and face a variety of reactions from social network members. Therefore, communication privacy management and communication accommodation theory was use to examine this phenomenon. Prior research found two different types of VCF couples: grounds-based and grounds-free. Grounds-based individuals cite medical or biological reasons for not having children, while grounds-free individuals cite social reasons for not having children. The purpose of this study is to examine how grounds-based and grounds-free VCF couples manage their disclosure of private information and how social network members react to their family planning decision. Findings revealed that grounds-free individuals are more likely to engage in the self-defense hypothesis and grounds-based individuals are more likely to engage in the expressive need hypothesis. Grounds-based individuals were asked about their decision in dyadic situations, whereas grounds-free individuals were asked at group gatherings. Additionally, social network members used under-accommodation strategies the most frequently and grounds-free individuals experienced more name calling than grounds-based. Finally, while grounds-free individuals experienced non-accommodation and …

Primary Stylistic Characteristics of Cindy McTee's Music as found in Timepiece, Ballet for Band and Finish Line (open access)

Primary Stylistic Characteristics of Cindy McTee's Music as found in Timepiece, Ballet for Band and Finish Line

Cindy McTee, Regents Professor of Composition in the College of Music at the University of North Texas, is one of America's leading composers. Her music is an eclectic blend of the "American" sound that is created by the use of a multiplicity of techniques. This document uses three of McTee's most recent (to date) works for wind band: Timepiece, Ballet for Band and Finish Line, to identify the primary stylistic characteristic's of the composer's music, which include: jazz influence; use of ostinati, pseudo-ostinati and machine-like rhythmic patterns and figures; creation of extended and angular melodic lines; progressive "walking" bass lines; and the use of octatonic and chromatic collections. Through the identification of stylistic characteristics, concise stylistic analysis of the works, interview transcript, list of composer's works to date, and selected discography, this document will add to the limited body of scholarly writing on the composer.

Learner-to-Learner: Refocusing the Lens of Educational Immediacy (open access)

Learner-to-Learner: Refocusing the Lens of Educational Immediacy

As the current body of instructional communication research focuses primarily on the relationship between teacher and learner, three studies investigating the relationship between learners were completed in order to better understand how student motivation and learning are influenced by learner-to-learner immediacy behaviors within the college classroom environment. Study I resulted in an extensive list of both positive and negative verbal and nonverbal immediacy behaviors commonly used by learners. Study II required the comparison of the behaviors identified in study one to existing measures of teacher to learner immediacy behaviors, producing a new measure focusing on learner-to-learner immediacy. Following a pilot survey, the reliability of this new measure was determined through face validity and factor analysis, producing the Learner-to-Learner Immediacy Behavior Scale. In Study III, the Learner-to-Learner Immediacy Behavior Scale was combined with Christophel's 1990 Immediacy Behavior Scale, Cognitive Learning Scale, Affective Learning Scale, and Trait and State Motivation Scales and administered to 273 undergraduate students to test the affects of common learner-to-learner immediacy behaviors on student state motivation, affective learning, and perceptions of cognitive learning loss. Multiple regression analyses indicated learner-to-learner immediacy as functioning similarly to teacher-to-student immediacy when mediated through state motivation in its influence on student affective learning …
