William E. Connolly's review of Peripheral Visions is what any author should want, a thoughtful, appreciative account of the book's merits and an invitation to push aspects of the argument further than the book currently does. One point of clarification: I did not mean to suggest that Foucault's work should be read only in terms of its emphasis on coherence and control, or that my own is intended as a blanket critique of his. My understanding of political power and resistance is beholden to Foucault's insofar as he shows how power depends on multiple points of resistance. He thus describes how existing mechanisms of social control get reproduced and yet are also vulnerable to creativity, innovation, and surprise. My point was to challenge Foucault-inspired scholars of colonialism, in particular, who tend to exaggerate the capacities of colonial administrations and to neglect not only outright challenges to colonial rule, but also the ways in which colonial rule could, at times, be irrelevant to inhabitants' political experience. The goal was to distinguish between the stated claims of colonial rulers and colonialism's actual effects. At stake is not simply a reading of Foucault, of course, but a sense of what matters politically—whether scholars emphasize the reproductive power of institutions and ideas or whether they focus on how reproduction places those very ideas and institutions at risk. I want to chart a middle course here, neither exaggerating coherence nor romanticizing resistance.

This study puts particular emphasis on the role of copper ions in the performance of hydrogen peroxide bleaching (P-stage). Owing to their variable levels across the bleaching line due to washing filtrates, bleaching reagents, and equipment corrosion, these ions can play a major role in hydrogen peroxide decomposition and be detrimental to polysaccharide integrity. In this study, a Cu-contaminated D0(EOP)D1 prebleached pulp was subjected to an acidic washing (A-stage) or chelation (Q-stage) before the alkaline P-stage. The objective was to understand the isolated and combined role of copper ions in peroxide bleaching performance. By applying an experimental design, it was possible to identify the main effects of the pretreatment variables on the extent of metals removal and performance of the P-stage. The acid treatment was unsuccessful in terms of complete copper removal, magnesium preservation, and control of hydrogen peroxide consumption in the following P-stage. Increasing reaction temperature and time of the acidic A-stage improved the brightness stability of the D0(EOP)D1AP bleached pulp. The optimum conditions for chelation pretreatment to maximize the brightness gains obtained in the subsequent P-stage with the lowest peroxide consumption were 0.4% diethylenetriaminepentaacetic acid (DTPA), 80ºC, and 4.5 pH.

The exercise of political power in late medieval English towns was predicated upon the representation, management, and control of public opinion. This chapter explains why public opinion mattered so much to town rulers; how they worked to shape opinion through communication; and the results. Official communication was instrumental in the politicization of urban citizens. The practices of official secrecy and public proclamation were not inherently contradictory, but conflict flowed from the political process. The secrecy surrounding the practices of civic government provoked ordinary citizens to demand more accountability from town rulers, while citizens, who were accustomed to hear news and information circulated by civic magistrates, were able to use what they knew to challenge authority.

In this article I review a series of artworks, artistic performances and installations that deal with the topic of surveillance. My aim is twofold. On the one hand, I want to look comparatively at how different artists interrogate, question, quote, or critise surveillance society. On the other hand, I take these artistic actions as themselves symptomatic of the ways in which surveillance interrogates contemporary society. In other words, my claim is that surveillance does not simply produce substantive social control and social triage, it also contributes to the formation of an ideoscape and a collective imagery about what security, insecurity, and control are ultimately about, as well as the landscape of moods a surveillance society like ours expresses.

A new silicon detector was designed by the CDF collaboration for Run IIb of the Tevatron at Fermilab. The main building block of the new detector is a "supermodule" or "stave", an innovative, compact and lightweight structure of several readout hybrids and sensors with a bus cable running directly underneath the sensors to carry power, data, and control signals to and from the hybrids. The hybrids use a new, radiation-hard readout chip, the SVX4 chip. A number of SVX4 chips, readout hybrids, sensors, and supermodules were produced and tested in preproduction. The performance (including radiation-hardness) and yield of these components met or exceeded all design goals. The detector design goals, solutions, and performance results are presented.

ABSTRACT OBJECTIVE The purpose of this investigation was to determine whether clinical speech deficits after brain injury are associated with functional speech reorganization. METHODS Across an 18-year interval, 11 patients with mild-to-moderate speech deficits underwent language mapping as part of their treatment for intractable epilepsy. These “aphasics” were compared with 14 matched “control” patients with normal speech who also were undergoing epilepsy surgery. Neuroanatomic data were compared with quantitative language profiles and clinical variables. RESULTS Cortical lesions were evident near speech areas in all aphasia cases. As expected, aphasic and control patients were distinguished by quantitative language profiles. The groups were further distinguished by the anatomic distribution of their speech sites. A significantly greater proportion of frontal speech sites was found in patients with previous brain injury, consistent with frontal site recruitment. The degree of frontal recruitment varied as a function of patient age at the time of initial brain injury; earlier injuries were associated with greater recruitment. The overall number of speech sites remained the same after injury. Significant associations were found between the number of the speech sites, naming fluency, and the lesion proximity in the temporal lobe. CONCLUSION Language maps in aphasics demonstrated evidence for age-dependent functional recruitment in the frontal, but not temporal, lobe. The proximity of cortical lesions to temporal speech sites predicted the overall extent of temporal lobe speech representation and performance on naming fluency. These findings have implications for neurosurgical planning in patients with preoperative speech deficits.

Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. To overcome the difficulties of traditional software development method, development of MES based on component is adopted to prompt development efficiency and performance of MES, which can be more reconstructing, reuse, expansion and integration, and MES domain analysis driven by ontology is investigated in detail. MES domain analysis driven by ontology is feasible and efficient through developing a pharmaceutics MES which applied in a pharmaceutics manufacturing factory.

In Zimbabwean society, what may not be spoken sometimes becomes acceptable in song – whether to avoid social taboos and enable a wife to complain against her mother-in-law, or in broadening the boundaries of political protest. In this article, Martin Rohmer looks back to the ways in which song enabled forms of protest against forced labour and other aspects of colonial rule – in times of outward compliance as well as of direct struggle – and considers how urban theatre groups in independent Zimbabwe have adapted the tradition to their own, contemporary ends. Martin Rohmer spent almost two years studying Zimbabwean theatre when a research assistant at the University of Bayreuth, and completed his doctorate on Theatre and Performance in Zimbabwe at the Humboldt University, Berlin, in 1997. Since then he has been working in the field of cultural management for the Young Artists' Festival in Bayreuth. The present paper was first presented at the Annual Meeting of the African Studies Association in San Francisco in November 1996.

This paper presents the design, analysis and testing of a fully actuated modular spherical tensegrity robot for co-robotic and space exploration applications. Robots built from tensegrity structures (composed of pure tensile and compression elements) have many potential benefits including high robustness through redundancy, many degrees of freedom in movement and flexible design. However to fully take advantage of these properties a significant fraction of the tensile elements should be active, leading to a potential increase in complexity, messy cable and power routing systems and increased design difficulty. Here we describe an elegant solution to a fully actuated tensegrity robot: The TT-3 (version 3) tensegrity robot, developed at UC Berkeley, in collaboration with NASA Ames, is a lightweight, low cost, modular, and rapidly prototyped spherical tensegrity robot. This robot is based on a ball-shaped six-bar tensegrity structure and features a unique modular rod-centered distributed actuation and control architecture. This paper presents the novel mechanism design, architecture and simulations of TT-3, the first untethered, fully actuated cable-driven six-bar tensegrity spherical robot ever built and tested for mobility. Furthermore, this paper discusses the controls and preliminary testing performed to observe the system’s behavior and performance.

Two studies were made of home visiting and psychosocial stimulation with deprived urban children in Jamaica. The aim was to determine the relative effectiveness of different frequencies of visiting on the children's developmental levels and the feasibility of integrating the model into government primary health care services. Health paraprofessionals supervised by a nurse from a local health center conducted the intervention. In the first study, 152 children aged 6 to 30 months were assigned to groups visited biweekly, monthly, or not at all by area of residence. The biweekly group showed small but significant increases in scores on the Griffiths Mental Development Scales (developmental quotient) and performance subscale compared with the monthly and control groups, whereas no benefit was shown in the Griffiths scores of the monthly group. In the second study, 58 children aged 16 to 30 months from the same neighborhoods were randomly assigned to weekly visited and control groups. The group visited weekly showed marked improvements in the performance and hearing and speech subscales as well as the developmental quotient scores. The results indicate that as the frequency of visiting increases from none through monthly and biweekly to weekly, the benefits increase as well.
