How Modern Family and Parenthood Represent Equal Parenting: A Feminist Discourse
Within recent discourses about parenting, the concept of equal parenting and fathering is a prominent theme. I have chosen two popular television shows that portray families to see if they represent ideas about equal parenting. I have identified three prominent themes that researchers agree comprise equal parenting: parents\u27 equal power in decision-making, fathers challenging masculine gender expectations by actively nurturing children, and fathers sharing household duties. The findings of this thesis conclude that the television shows Parenthood and Modern Family are contradictory in their representations of equal parenting themes. Parenthood has strong examples of equal parenting, but remains more conservative in the representation of traditional gender roles, while Modern Family\u27s representation of family is more liberal, not enforcing gender expectations on the family with two gay fathers, yet the fathers with different-sex partners are not allotted the same flexibility in their gender roles
The unmet needs of Aboriginal Australians with musculoskeletal pain: A mixed method systematic review
Objective: Musculoskeletal pain (MSP) conditions are the biggest cause of disability and internationally, Indigenous peoples experience a higher burden. There are conflicting reports about Aboriginal Australians and MSP. We conducted a systematic review to describe the prevalence, associated factors, impacts, care access, health care experiences, and factors associated with MSP among Aboriginal Australians.
Methods: A systematic search of quantitative and qualitative scientific and grey literature (PROSPERO number: CRD42016038342). Articles were appraised using the Mixed Methods Appraisal Tool. Due to study heterogeneity a narrative synthesis was conducted.
Results: Of 536 articles identified, 18 were included (14 quantitative, 4 qualitative), of high (n=11), medium (n=2) and low (n=5) quality. Prevalences of MSP in Aboriginal populations were similar to or slightly higher than the nonâAboriginal population (prevalence rate ratio 1.1 for back pain, 1.2â1.5 for osteoarthritis (OA), 1.0â2.0 for rheumatoid arthritis). Aboriginal people accessed primary care for knee or hip OA at around half the rate of nonâAboriginal people, and were less than half as likely to have knee or hip replacement surgery. Communication difficulties with health practitioners were the main reason why Aboriginal people with MSP choose not to access care. No articles reported interventions.
Conclusions: Findings provide preliminary evidence of an increased MSP burden amongst Aboriginal Australians and, particularly for OA, a mismatch between the disease burden and access to health care. To increase accessibility, health services should initially focus on improving Aboriginal patientsâ experiences of care, in particular by improving patientâpractitioner communication. Implications for care and research are outlined
Gas and gas hydrate distribution around seafloor seeps in Mississippi Canyon, Northern Gulf of Mexico, using multi-resolution seismic imagery
This paper is not subject to U.S. copyright. The definitive version was published in Marine and Petroleum Geology 25 (2008): 952-959, doi:10.1016/j.marpetgeo.2008.01.015.To determine the impact of seeps and focused flow on the occurrence of shallow gas hydrates, several seafloor mounds in the Atwater Valley lease area of the Gulf of Mexico were surveyed with a wide range of seismic frequencies. Seismic data were acquired with a deep-towed, Helmholz resonator source (220â820 Hz); a high-resolution, Generator-Injector air-gun (30â300 Hz); and an industrial air-gun array (10â130 Hz). Each showed a significantly different response in this weakly reflective, highly faulted area. Seismic modeling and observations of reversed-polarity reflections and small scale diffractions are consistent with a model of methane transport dominated regionally by diffusion but punctuated by intense upward advection responsible for the bathymetric mounds, as well as likely advection along pervasive filamentous fractures away from the mounds.This work was funded through ONR

Retrovirus Integration Database (RID): A public database for retroviral insertion sites into host genomes
The NCI Retrovirus Integration Database is a MySql-based relational database created for storing and retrieving comprehensive information about retroviral integration sites, primarily, but not exclusively, HIV-1. The database is accessible to the public for submission or extraction of data originating from experiments aimed at collecting information related to retroviral integration sites including: the site of integration into the host genome, the virus family and subtype, the origin of the sample, gene exons/introns associated with integration, and proviral orientation. Information about the references from which the data were collected is also stored in the database. Tools are built into the website that can be used to map the integration sites to UCSC genome browser, to plot the integration site patterns on a chromosome, and to display provirus LTRs in their inserted genome sequence. The website is robust, user friendly, and allows users to query the database and analyze the data dynamically. Availability: https://rid.ncifcrf.gov; or http://home.ncifcrf.gov/hivdrp/resources.htm
Dissolved methane in the Beaufort Sea and the Arctic Ocean, 1992-2009; sources and atmospheric flux
Methane concentration and isotopic composition was measured in ice-covered and ice-free waters of the Arctic Ocean during 11 surveys spanning the years of 1992â1995 and 2009. During ice-free periods, methane flux from the Beaufort shelf varies from 0.14 mg CH4 mâ2 dâ1 to 0.43 mg CH4 mâ2 dâ1. Maximum fluxes from localized areas of high methane concentration are up to 1.52 mg CH4 mâ2 dâ1. Seasonal buildup of methane under ice can produce short-term fluxes of methane from the Beaufort shelf that varies from 0.28 mg CH4 mâ2 dâ1 to 1.01 mg CH4 mâ2 dâ1. Scaled-up estimates of minimum methane flux from the Beaufort Sea and pan-Arctic shelf for both ice-free and ice-covered periods range from 0.02 Tg CH4 yrâ1 and 0.30 Tg CH4 yrâ1, respectively to maximum fluxes of 0.18 Tg CH4 yrâ1 and 2.2 Tg CH4 yrâ1, respectively. A methane flux of 0.36 Tg CH4 yrâ1 from the deep Arctic Ocean was estimated using data from 1993 to 1994. The flux can be as much as 2.35 Tg CH4 yrâ1 estimated from maximum methane concentrations and wind speeds of 12 m/s, representing only 0.42% of the annual atmospheric methane budget of ⌠560 Tg CH4 yrâ1. There were no significant changes in methane fluxes during the time period of this study. Microbial methane sources predominate with minor influxes from thermogenic methane offshore Prudhoe Bay and the Mackenzie River delta and may include methane from gas hydrate. Methane oxidation is locally important on the shelf and is a methane sink in the deep Arctic Ocean
Is Strangeness still interesting at RHIC ?
With the advent of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven
National Laboratory (BNL), Heavy Ion Physics will enter a new energy regime.
The question is whether the signatures proposed for the discovery of a phase
transition from hadronic matter to a Quark Gluon Plasma (QGP), that were
established on the basis of collisions at the BEVALAC, the AGS, and the SPS,
respectively, are still useful and detectable at these high incident energies.
In the past two decades, measurements related to strangeness formation in the
collision were advocated as potential signatures and were tested in numerous
fixed target experiments at the AGS and the SPS. In this article I will review
the capabilities of the RHIC detectors to measure various aspects of
strangeness, and I will try to answer the question whether the information
content of those measurements is comparable to the one at lower energies.Comment: 12 pages, 7 figures, Invited Talk at the IV International Conference
on Strangeness in Quark Matter, Padova (Italy), July 20-24, 199
Establishing the relationship between manufacturing and component performance in stretch formed thermoplastic composites
Flexible manufacturing methods are needed to reduce the cost of using advanced composites in structural applications. One method that allows for this is the stretch forming of long discontinuous fiber materials with thermoplastic matrices. In order to exploit this flexibility in an economical way, a thorough understanding of the relationship between manufacturing and component performance must be developed. This paper reviews some of the recent work geared toward establishing this understanding. Micromechanics models have been developed to predict the formability of the material during processing. The latest improvement of these models includes the viscoelastic nature of the matrix and comparison with experimental data. A finite element scheme is described which can be used to model the forming process. This model uses equivalent anisotropic viscosities from the micromechanics models and predicts the microstructure in the formed part. In addition, structural models have been built to account for the material property gradients that can result from the manufacturing procedures. Recent developments in this area include the analysis of stress concentrations and a failure model each accounting for the heterogeneous material fields
