TL;DR: In this paper, an ethnographic study of distributors for Amway, a network marketing organization, examines the practices and processes involved in managing members' organizational identification and shows that this organization manages identification by using two types of practices: sensebreaking practices that break down meaning and sensegiving practices that provide meaning.
Abstract: An ethnographic study of distributors for Amway, a network marketing organization, examines the practices and processes involved in managing members' organizational identification. It shows that this organization manages identification by using two types of practices: sensebreaking practices that break down meaning and sensegiving practices that provide meaning. When both sensebreaking and sensegiving practices are successful, members positively identify with the organization. When either sensebreaking or sensegiving practices fail, members deidentify, disidentify, or experience ambivalent identification with the organization. A general model of identification management is posited, and implications for both theory and practice are offered.

TL;DR: An ultrathin, compliant skin-like sensor/actuator technology that can pliably laminate onto the epidermis to provide continuous, accurate thermal characterizations that are unavailable with other methods are introduced.
Abstract: Precision thermometry of the skin can, together with other measurements, provide clinically relevant information about cardiovascular health, cognitive state, malignancy and many other important aspects of human physiology. Here, we introduce an ultrathin, compliant skin-like sensor/actuator technology that can pliably laminate onto the epidermis to provide continuous, accurate thermal characterizations that are unavailable with other methods. Examples include non-invasive spatial mapping of skin temperature with millikelvin precision, and simultaneous quantitative assessment of tissue thermal conductivity. Such devices can also be implemented in ways that reveal the time-dynamic influence of blood flow and perfusion on these properties. Experimental and theoretical studies establish the underlying principles of operation, and define engineering guidelines for device design. Evaluation of subtle variations in skin temperature associated with mental activity, physical stimulation and vasoconstriction/dilation along with accurate determination of skin hydration through measurements of thermal conductivity represent some important operational examples.

17 Jun 2007TL;DR: A novel algorithm for calibrated multi-view stereopsis that outputs a (quasi) dense set of rectangular patches covering the surfaces visible in the input images, which is currently the top performer in terms of both coverage and accuracy for four of the six benchmark datasets presented in [20].
Abstract: This paper proposes a novel algorithm for calibrated multi-view stereopsis that outputs a (quasi) dense set of rectangular patches covering the surfaces visible in the input images. This algorithm does not require any initialization in the form of a bounding volume, and it detects and discards automatically outliers and obstacles. It does not perform any smoothing across nearby features, yet is currently the top performer in terms of both coverage and accuracy for four of the six benchmark datasets presented in [20]. The keys to its performance are effective techniques for enforcing local photometric consistency and global visibility constraints. Stereopsis is implemented as a match, expand, and filter procedure, starting from a sparse set of matched keypoints, and repeatedly expanding these to nearby pixel correspondences before using visibility constraints to filter away false matches. A simple but effective method for turning the resulting patch model into a mesh appropriate for image-based modeling is also presented. The proposed approach is demonstrated on various datasets including objects with fine surface details, deep concavities, and thin structures, outdoor scenes observed from a restricted set of viewpoints, and "crowded" scenes where moving obstacles appear in different places in multiple images of a static structure of interest.

TL;DR: In this article, the authors present recent progress in understanding and manipulation of energy dissipation and transport in nanoscale solid-state structures, including silicon transistors, carbon nanostructures, and semiconductor nanowires.
Abstract: Understanding energy dissipation and transport in nanoscale structures is of great importance for the design of energy-efficient circuits and energy-conversion systems. This is also a rich domain for fundamental discoveries at the intersection of electron, lattice (phonon), and optical (photon) interactions. This review presents recent progress in understanding and manipulation of energy dissipation and transport in nanoscale solid-state structures. First, the landscape of power usage from nanoscale transistors (∼10−8 W) to massive data centers (∼109 W) is surveyed. Then, focus is given to energy dissipation in nanoscale circuits, silicon transistors, carbon nanostructures, and semiconductor nanowires. Concepts of steady-state and transient thermal transport are also reviewed in the context of nanoscale devices with sub-nanosecond switching times. Finally, recent directions regarding energy transport are reviewed, including electrical and thermal conductivity of nanostructures, thermal rectification, and the role of ubiquitous material interfaces.

TL;DR: In this paper, the authors argue that new product development (NPD) teams are engaged in knowledge creation, and NPD management should emphasize cognitive team processes rather than purely social processes.
