Collecting Women’s Art and Native American Artificates: Issues for Museum Curators

Egalitarianism is quite possibly the education buzzword of the eighties. Egalitarianism is belabored in the literature of late that it seems inconceivable that any person or institution with any degree of social responsibility has not yet acted to realign the programs and policies of our biased past. Yet many major social groups still remain disenfranchised in the current American cultural scenario. This commentary addresses the predicament of two of those groups-women and Native Americans. While seemingly unrelated, both groups share a common dilemma: their voices, their opinions and their expressions are not yet respected in the realm of art and history museums. Women consistently find little or no value placed on their artistic expressions, and Native Americans find their values and wishes utterly violated. While focusing on the plight of these two groups and the roles played by museums in determining the respect and value bestowed upon objects and people, let us not forget that there are many other groups whose work is mistreated or ignored and whose voices are not yet equally respected by those who dictate museum policy

Finding Meaning for Postmodernism

Recent media hype throughout the land has brought wide-spread conversation on the phenomenon known as postmodernism. True to its nature, the media (while propelling the rapid dissemination of the term itself) gives us very little insight into the history/meaning/concepts/origin/definition or effects of the now quite fashionable designation

Variable-camber systems integration and operational performance of the AFTI/F-111 mission adaptive wing

The advanced fighter technology integration, the AFTI/F-111 aircraft, is a preproduction F-111A testbed research airplane that was fitted with a smooth variable-camber mission adaptive wing. The camber was positioned and controlled by flexing the upper skins through rotary actuators and linkages driven by power drive units. The wing camber and control system are described. The measured servoactuator frequency responses are presented along with analytical predictions derived from the integrated characteristics of the control elements. A mission adaptive wing system chronology is used to illustrate and assess the reliability and dependability of the servoactuator system during 1524 hours of ground tests and 145 hours of flight testing

Disabling and enabling geographies : Celebrating 20 years of research in Social and Cultural Geography

The geographies of disability have been an important and enduring part of Social and Cultural Geography since its inception. The journal has featured more than 100 research papers on different dimensions of disability, illness, impairment, ableism and (in)accessibility. In this virtual special issue, we selected ten of these papers to highlight key theoretical and empirical contributions made within the journal. These include the careful spatial theorisation of lived experiences of disabilities, and critical analyses of shifting landscapes and politics of care and support that shape the lives of many disabled people. Collectively, these papers also signpost avenues for future research such as engaging with relational and more-than-human geographies, and the development of a more global politics of disability

Evidence for wind-forced circulation in the Gulf of Mexico

A study is conducted into the response of sea level and dynamic height to fluctuations of alongshore wind stress and wind stress curl at periods greater than a few months per cycle…

Systematic Breeding Decisions Made Within A Vertically Integrated Beef Supply Chain

This paper investigates how to use a vertically integrated supply-chain model to aid in the selection of beef sires when making breeding decisions. A systematic approach was taken to model and determine the benefits and associated sire rankings arising from the simulated mating of parent stock to create progeny for use within a vertically integrated supply chain. Supply chain-wide gross margins serve as the benefit measure. Supply chain revenues are in the form of quality indexed retail product revenue. Quality indexing (i.e. discounting) factors included intramuscular fat and longissimus muscle (i.e. ribeye) area. A fixed and an optimum endpoint (i.e. harvest) selection method are compared. Varying progeny gross margins and sire rankings were produced. The various levels of gross margin were significantly different from zero, and provide a clear means by which to incorporate economic variables into selection of beef sires. No current method of selecting parental stock returns similar results.value-chain management, beef-cattle breeding, Industrial Organization, Livestock Production/Industries,

Design, simulation, and characterization of a radial opposed migration ion and aerosol classifier (ROMIAC)

We present the design, simulation, and characterization of the radial opposed migration ion and aerosol classifier (ROMIAC), a compact differential electrical mobility classifier. We evaluate the performance of the ROMIAC using a combination of finite element modeling and experimental validation of two nearly identical instruments using tetra-alkyl ammonium halide mass standards and sodium chloride particles. Mobility and efficiency calibrations were performed over a wide range of particle diameters and flow rates to characterize ROMIAC performance under the range of anticipated operating conditions. The ROMIAC performs as designed, though performance deviates from that predicted using simplistic models of the instrument. The underlying causes of this non-ideal behavior are found through finite element simulations that predict the performance of the ROMIAC with greater accuracy than the simplistic models. It is concluded that analytical performance models based on idealized geometries, flows, and fields should not be relied on to make accurate a priori predictions about instrumental behavior if the actual geometry or fields deviate from the ideal assumptions. However, if such deviations are accurately captured, finite element simulations have the potential to predict instrumental performance. The present prototype of the ROMIAC maintains its resolution over nearly three orders of magnitude in particle mobility, obtaining sub-20 nm particle size distributions in a compact package with relatively low flow rate operation requirements
