Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Migration and workforce aging
No full textThis chapter reviews recent research on migration and workforce aging, and examines the relationship between policy and practice in this contested area. At present, most attention has focused on the extent to which migrant labour can replenish labour stocks in aging societies, and to a lesser extent on the impact of emigration on the countries that export significant proportions of their population. There has until recently been much less focus on the experiences of older migrants, though this now appears to be changing
Graphic standards field guide to hardscape / Leonard J. Hopper.
No full textIncludes index.ix, 486 pages :"Part of Wiley's new Graphic Standard Field Guides series, Graphic Standards Field Guide to Hardscape is the reference for the on-the-go professional. The perfect companion to the main Landscape Architectural Graphic Standards, this field guide provides the same standard architectural details and drawings that professionals count on from Graphic Standards, and adds photographs and interpretive information that are essential when outside the office and away from the design desk. The small trim size and durable binding makes it easy for landscape architects and designers to keep this resource on hand when on site, at meetings, or with clients. Organized to follow CSI's MasterFormat, this handy reference helps the landscape architect address a wide variety of practical issues pertaining to hardscape including site work, bases and paving, site improvements, furnishing and equipment, and services. A procedural checklist makes sure nothing's missed on site"-

Crack Tip Field and J-Integral with Strain Gradient Effect
No full textThe mode I plane strain crack tip field with strain gradient effects is presented in this paper based on a simplified strain gradient theory within the framework proposed by Acharya and Bassani. The theory retains the essential structure of the incremental version of the conventional J_2 deformation theory No higher-order stress is introduced and no extra boundary value conditions beyond the conventional ones are required. The strain gradient effects are considered in the constitutive relation only through the instantaneous tangent modulus. The strain gradient measures are included into the tangent modulus as internal parameters. Therefore the boundary value problem is the same as that in the conventional theory Two typical crack Problems are studied: (a) the crack tip field under the small scale yielding condition induced by a linear elastic mode-I K-field and (b) the complete field for a compact tension specimen. The calculated results clearly show that the stress level near the crack tip with strain gradient effects is considerable higher than that in the classical theory The singularity of the strain field near the crack tip is nearly equal to the square-root singularity and the singularity of the stress field is slightly greater than it. Consequently, the J-integral is no longer path independent and increases monotonically as the radius of the calculated circular contour decreases
Skin-friction field in turbulent convection
No full textThe dynamics of the boundary layers of temperature and velocity are the key to deeper understanding of turbulent transport of heat and momentum in thermal convection. Here, the structure of the skin friction field at the bottom and top plates of a Rayleigh-B\'{e}nard convection setup is investigated. We therefore analyze data obtained in direct numerical simulations of Rayleigh-B\'{e}nard convection in a cylindrical cell of aspect ratio . Our analysis is focused to critical points of the two-dimensional skin friction field at the walls. We analyze the statistics of the critical points and relate them to the thermal plumes which detach from the wall and move up into bulk
