Objective. The aim of the current study is to explore the association between combat experience and the occurrence of delusional-like beliefs. It is hypothesized that negative post-trauma appraisals and positive beliefs about paranoia will be associated with vulnerability to delusional ideas and that veterans who meet criteria for post-traumatic stress disorder (PTSD) will be more likely to hold delusional-like ideas. Design. A small-scale survey design was employed in order to ensure that detailed information was gathered concerning battle exposure. Methods. Forty-one British war veterans completed questionnaires relating to combat experience, delusional ideation, beliefs about paranoia, appraisals of combat trauma and PTSD symptomatology. Results. Negative post-trauma cognitions and positive and negative beliefs about paranoia were associated with increased predisposition to delusional beliefs;however, the severity of combat experience was not. It was also found that veterans who met criteria for PTSD were more likely to hold delusional-like ideas compared with those who did not. Furthermore, the PTSD group held more negative post-trauma cognitions and more positive beliefs about paranoia. Conclusions. These findings suggest that PTSD symptoms may confer vulnerability to delusional beliefs and that this may be mediated by negative appraisals about the self, the world and dysfunctional beliefs about paranoia. However, it is possible that psychotic-like phenomena confer vulnerability to PTSD. The implications of these findings are discussed.

Landscape architect Ron Lutsko, ASLA, whose San Francisco firm works on estate gardens, discovered that meshing his signature brand of spare modernist garden with a large classical structure was feasible when he scattered his ideas around a client s property. Lutsko used to teach landscape architecture at the University of California at Berkeley, and he still likes to disseminate design ideas in subliminal, creative ways. The manor house, designed for a family of four in Hillsborough, California, sits on five acres that provide ample room for experimentation.

Commissioned to design a new corporate building, the nineteenth-or earlytwentieth-century architect would expect to receive a detailed brief listing the required placeswithin it and an idea of their appropriate hierarchical disposition. From this process could arisean architectural identity which would be further embellished with some suitable symbolic decorationand signage.

This article considers how ideas from evolutionary theory in general, and Sidney Winter in particular, can be fruitfully combined with ideas from Herbert Simon and the Carnegie tradition on decomposability and cognitive limits. Rather than focusing on any one individual issue, this article outlines a research program on the architecture and design of organizational capabilities. Such a program can help us explain how labor is divided and organized within and between firms and can consider the implications of the division of labor for the process of capability development. Extensions to this emerging research program are proposed: The emergence and evolution of intra-and inter-organizational boundaries, the implications of such boundaries for different types of capabilities and for the knowledge accumulation process, and the design of firms' architecture to support adaptation and change are all briefly discussed.

This paper addresses adaptive detection of possibly rangespread targets without resorting to secondary data, namely data free of signal components, but sharing the spectral properties of those under test. More precisely, detection of coherent target echoes embedded in Gaussian noise with unknown covariance matrix has been attacked by approximating the covariance matrix of the noise as a block diagonal one with identical diagonal blocks;moreover, each block is estimated froma set of subvectors obtained by filtering out possible signal components from data under test. The proposed detector guarantees the Constant False Alarm Rate (CFAR) property with respect to the noise power. In addition, its threshold setting seems not very sensitive to the actual structure of covariance matrix. Finally, a preliminary performance assessment, also conducted using real high range resolution radar data from an urban scene, has shown that it might be a viable means to deal with uncertain scenarios.

Pyrometallurgy is an ancient art which has defined significant stages of human development. Today, new opportunities for improvements in the economic, environmental, and workplace costs of metal production continue to provide challenges for the profession and industry. Top-submerged lancing technology for the high-temperature processing of a range of metals and wastes is an example that has been taken up by many companies around the world. The furnace system now marketed under the names of Ausmelt and Isasmelt was, in the early stage of its 33 years of development, known as Sirosmelt. The voyage from the original idea through theoretical, laboratory, pilot plant, and commercial developments to establishment of a worldwide business has been both stimulating and rewarding.

Breast cancer starts as a local disease, but it can metastasize to the lymph nodes and distant organs. At primary diagnosis, prognostic markers are used to assess whether the transition to systemic disease is likely to have occurred. The prevailing model of metastasis reflects this view - it suggests that metastatic capacity is a late, acquired event in tumorigenesis. Others have proposed the idea that breast cancer is intrinsically a systemic disease. New molecular technologies, such as DNA microarrays, support the idea that metastatic capacity might be an inherent feature of breast tumours. These data have important implications for prognosis prediction and our understanding of metastasis.

I have a problem with writing. It started on a particular day, seven yearsago. That day everything changed somehow and all the changes were of the utmost importance. I had torecord them. One day I noticed that I was crouched on the floor of a bathroom in the building whereI worked as a neurologist, writing on toilet paper because the idea couldn''t wait until I got backto my office. When there was no paper, I wrote on my forearms. As my ideas got more intense, I evenwrote on myself while I was driving. The change in my writing came 10 days after I gave birthprematurely to twin boys, who died. They were so small - one held my finger before he died, and hishand hardly fitted around it. For nine days my grief was ''appropriate''. On the tenth, I woke wildlyexcited, filled with hundreds of ideas pressing to be written down.

The work of Tezuka Architects has always had an ingenious, playful *** House (AR October 2001) gave us the naughty-but-nice example of the balustrade-free slopingroof terrace, subsequently copied by many misguided European students where the idea would becompletely *** twist in the tail of their snake-like Natural Science Museum (AR August2004) was the use of 75mm thick acrylic windows to retain smothering snowdrifts. And, more recently,the Big Window House completed in Yokohama, recalls Mies' Tugendhat House with its massive fallingglass wall (main photograph, Delight, p98). Here then, with the completion of the Engawa House inTokyo, a gravity-defying slot window creates a unique relationship between two neighbouring homes.
