Language,Life, Code

Software increasingly determines what can be designed, constructed and even how design occurs. Here, Alexander R Galloway and Eugene Thacker present a series of investigations with the collaborative Radical Software Group (RSG). Their practice examines the nature of software code as a form of language. Addressing theoretical issues regarding meaning and representation, they argue for thinking more abstractly and generatively about language, and propose a new, or liberated, computer language in which the representational determinations implicit to any software are geared towards innovation in communication and design. By rewriting the software that allows for the transmission and translation of knowledge across previously discrete fields of production, programming allows for new and productive cross-pollination. Indeed, programming becomes a new site of design that enfolds disciplines not traditionally seen as part of the creative processes of innovation. Copyright © 2006 John Wiley & Sons, Ltd.     

Bogotá and Medellín: Architecture and Politics

In the last 15 years, Bogotá and Medellín, Colombia's two largest cities, have undergone urban renaissances. These are a direct result of a political will to tackle the social, economic and physical segregation caused by the large-scale urban migrations of the 1970s and 1980s, which resulted in informal developments that were often isolated from central urban areas with no infrastructure. Lorenzo Castro and Alejandro Echeverri describe the shared experiences and distinct approaches of each city. Copyright © 2011 John Wiley & Sons, Ltd.     

Effectiveness of security analyst information accessing strategies: A computer interactive assessment

The present study illustrates how computers can substantially extend the range and ease of application of the behavioral process information monitoring procedures that are increasingly being used to capture and preserve traces of pre-decision information accessing behavior. Employing such an extension, the study examined whether better and poorer decision marker performance was related to differences in the extent and content of information accessing behavior. The results of a computer simulation involving practicing financial security analysts engaged in a securities analysis task revealed that the better performing analysts generally considered slightly greater amounts of information and different types of information than did the poorer performing analysts. These findings are interpreted in terms of the concept of “control schemas” postulated by Kozminsky, Kintsch, and Bourne (1981). A concluding section describes numerous ways in which computers improve upon both the flexibility and validity of traditional research paradigms.     

Jacob假定下含水层的储水率及其地面沉降机理意义

通过在Jacob假定下推导储水率与多孔弹性介质的物理力学常参数之间的联系,发现储水率的骨架弹性贡献部分为与时间无关的常数。进一步推导发现地面沉降与地下水头降深之间具有线性关系。其中水头降深是地面沉降的主动因素,是外因;骨架弹性储水率和储水层厚度是被动因素,是内因。三种因素对地面沉降都做正比贡献。对地表某一确定点而言,由于骨架弹性储水率和储水层厚度相对稳定,地面沉降与地下水头降深成正比．地表以下全部垂向形变储水层的综合骨架弹性储水系数为其比例系数。相同的水头降深可以带来不同的地面沉降,也就是说,地面沉降漏斗相对于地下水头降落漏斗可能会有不同程度的偏离．这是由于平面上各点处的垂向压缩土层的厚度及综合骨架弹性储水系数不尽相同所致。地面沉降与地下水头下降之间普遍呈现显著线性相关关系的事实反过来表明,储水层的垂向释水压密变形规律基本符合Jacnh假定;其线性比例系数应为地表以下所有形变储水层的综合骨架弹性储水系数。     

乾、嘉时期长芦盐商群体衰落现象分析

乾、嘉时期,长芦盐商群体经历了一次明显的衰落过程。盐业运营(或专卖)是经济行为,要从经济规律中寻找长芦盐商群体衰落的原因。盐商的垄断地位是各种危机的根源,各方都试图从中获利导致乾嘉时期各种陋规逐渐公开化;盐商的报效实际上是最大的陋规。长芦盐商靠提高盐价来确保各方利益,同时也使得私盐泛滥,最终侵害了盐业运营和盐商可持续发展的根基。另一方面,"银贵钱贱"侵蚀了长芦盐商很大一部分利润。清代的"银贵钱贱"现象并不是随着鸦片贸易出现的,与长芦盐业有关的"银贵钱贱"现象早在雍正九年已经出现,引入"杰科布定律",能够很好地解释由盛世而物价上升,由物价上升而"银贵钱贱"的基本路径。     

A Sketchbook for the City to Come: The Pop-Up as R&D

Dan Hill , an Executive Director at Future Cities Catapult, is not content to accept that architecture is willy-nilly the carapace for the desires of the society that constructs it. He argues that pop-ups – all too often the tools of corporate branding or the cat's paw of gentrification – should be used to implement overt social initiatives, presaging an architecture of positive change in cities. A member of the Finnish Innovation Fund Sitra's Strategic Design Unit from 2011 to 2012, he helped lead the Open Kitchen initiative featured here.     

基于Jacob与POI操作复杂报表的动态模板法

在研究POI、JXL、Jacob、JFreeChart组件以及宏在报表输出中的优势与不足的基础上,提出Jacob与POI相结合的动态模板法。首先用Jacob生成只包含chart对象的Excel动态模板,然后结合POI读取、修改Excel功能写入其他信息。并充分利用Jacob与VBA对Excel操作的相关性,方便了Jacob的使用,有效解决了带有chart复杂报表输出的问题。最后结合实例详述了动态模板法的实现过程。     

Jack Block (1924 –2010).

Born Jacob Block in Brooklyn, New York, on April 28, 1924, Jack received his bachelor’s degree from Brooklyn College. Block is one of the most influential personality and developmental psychologists of his generation and of the 20th century; at the same time, he established himself as a pioneer and authority on applications of multivariate statistics to psychological data. Block became involved with an existing longitudinal research project at Berkeley, found insightful ways to bring order out of previously unused anecdotal and informal data, and used it to publish the influential Lives through time (1971, Bancroft). Equally important were Block’s contributions to statistical methodology and personality assessment. The challenge of response sets (1965, Appleton-Century-Crofts) nearly single-handedly restored confidence in substantive interpretations of self-report measures of personality; and his demonstrations of the utility of observer evaluations and elaboration of the Q-sort method (The Q-sort method in personality assessment and psychiatric research, 1961, Thomas) helped establish the knowledgeable observer as a valuable source of psychological information. Block was ahead of his time on two other major analytic issues: latent variable modeling and empirical sampling distributions for statistical inference. Block also became well-known for his energetic participation in research controversies. As a key participant in the “person–situation debate,” he argued for the lifelong coherence of personality. After decades of health challenges, he insisted on being taken home, where he could be surrounded by his music, his art, and his family and where he died on January 13, 2010.
