Validation of the Minnesota Scale of Parental Occupations and a modification of the Werner Occupational Rating Scale.

The Minnesota and Warner scales were correlated with material and cultural possession criteria for a sample of 150 urban high school students and 150 rural students. The substantial but not high correlation between the scales and criteria is attributed to the present wide distribution of the criteria possessions in the population, so that they no longer act as adequate socioeconomic differentiators. The Warner scale seems to differentiate more adequately among agricultural occupations than the Minnesota scale. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

All Night Long: The Architectural Jazz of the Texas Rangers

In the mid-1950s, a group of young faculty at the University of Texas School of Architecture in Austin - aka the Texas Rangers - entertained themselves with weekly sessions of a sophisticated, collective drawing game, ‘Dot-the-Dot’, in which there was an emphasis on inventive fluency in hand drawing as well as an innate knowledge of historic European city plans. What happened when Mark Morris , Visiting Associate Professor at Cornell University, decided in a design studio to ask present-day students to revive the game?     

腔QED中混态双原子系统的原子布居数演化

运用全量子理论和数值计算方法,研究了双J-C模型中处于混态的双原子系统粒子布居差的时间演化规律,讨论了原子初态及腔内光场对粒子布居差演化的影响。计算结果表明：当两腔内的平均光子数相同时,布居差的演化只与两原子的初态纯度和光场强度有关,与两原子的初始纠缠无关;而当两光腔内的平均光子数不同时,粒子布居差演化不仅与两原子初态纯度和腔内光场有关,而且还强烈地依赖于两原子的初始纠缠。

Abstract

During the last two years of his life, Ralph Eugene Meatyard assembled a series of photographs into a book titled The Family Album of Lucybelle Crater. The album's main subject is his wife Madelyn Meat yard who wore one mask for the title role of Lucybelle Crater, and appeared in sixtyfour photographs accompanied in each by a different person wearing one other mask. Madelyn Meat yard's mask, an opaque representation of a grotesque hag, is described as resembling ‘Mammy Yokum from Outer Space’.¹ The other mask is transformed by its wearer, for it is a translucent representation of an androgynous older person. Only two images are titled, and the real names of the masked people are revealed in a listing at the end of the book.     

On the Threshold of Rationalism

No longer a leading architectural trend, Rationalism has fallen out of fashion. At best ‘marginalised’, even its tenets appear questionable. Guest-editors Andrew Peckham, Charles Rattray and Torsten Schmiedeknecht describe what motivated them to uncover and reassess the Rationalist sensibility among current European practices.

Embedding Intelligence: Architecture and Computation at Grimshaw,NY

Research and development at Grimshaw is concentrated in two groups: Design Technology (DT) and Industrial Design (ID). Seth Edwards from Grimshaw's DT group explains how these dual hubs provide an essential resource for the practice, offering expertise in complex geometry, rapid prototyping and construction. He illustrates three projects, originating in the New York office, that exemplify this approach.     

Loss of p16(Ink4a) Function Rescues Cellular Senescence Induced by Telomere Dysfunction

p16(Ink4a) is a tumor suppressor and a marker for cellular senescence. Previous studies have shown that p16(Ink4a) plays an important role in the response to DNA damage signals caused by telomere dysfunction. In this study, we crossed Wrn(-/-) and p16(Ink4a-/-) mice to knock out the p16(Ink4a) function in a Wrn null background. Growth curves showed that loss of p16(Ink4a) could rescue the growth barriers that are observed in Wrn(-/-) mouse embryonic fibroblasts (MEFs). By challenging the MEFs with the global genotoxin doxorubicin, we showed that loss of p16(Ink4a) did not dramatically affect the global DNA damage response of Wrn(-/-) MEFs induced by doxorubicin. However, in response to telomere dysfunction initiated by the telomere damaging protein TRF2(ΔBΔM), loss of p16(Ink4a) could partially overcome the DNA damage response by disabling p16(Ink4a) up-regulation and reducing the accumulation of γ-H2AX that is observed in Wrn(-/-) MEFs. Furthermore, in response to TRF2(ΔBΔM) overexpression, Wrn(-/-) MEFs senesced within several passages. In contrast, p16(Ink4a-/-) and p16(Ink4a-/-)Wrn(-/-) MEFs could continuously grow and lose expression of the exogenous TRF2(ΔBΔM) in their late passages. In summary, our data suggest that in the context of telomere dysfunction, loss of p16(Ink4a) function could prevent cells from senescence. These results shed light on the anti-aging strategy through regulation of p16(Ink4a) expression.     

Almost All Right: Vienna's Social Housing Provision

The aim of social housing is to manage scarcity by providing affordable accommodation for everyone. Responding to shifts in demand, it also has to adapt to ever-changing economic, political and social conditions. Here, Andreas Rumpfhuber, Michael Klein and Georg Kolmayr look at Vienna's social housing provision, which for over a century has been ‘dealing with scarcity and its ghosts in order to avoid its negative effects’.     

Exist-Stencil

Architect and interior designer Jeffrey James admits an ambivalent attitude towards nature. Here he turns that ambivalence to positive effect through a series of poetic digital collages that provide a mediation between ‘our incomprehension of the vast magnificence and complexity of the natural world and the actual spaces that we can physically touch and inhabit’.     

Radical Sources of Design Engineering

The German architect and structural engineer, Werner Sobek is internationally renowned for his expertise in lightweight structures - an approach that is epitomised by the dramatic elegance of his glazed House R128. Here, Sobek explains how his practice has extended a highly specialised focus on ultra-lightweight facades to that of building structures, facade planning, and sustainable and low-energy solutions, interweaving research and innovation with design and consultancy work.
