Advanced perceptual systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation. I propose a unified approach to visual representation, addressing the need for superordinate and basic-level categorization and for the identification of specific instances of familiar categories. According to the proposed theory, a...

Previous investigations have demonstrated the existence of basophilic, intracytoplasmic inclusions in epithelial cells obtained from the anterior urethra of nongonococcal urethritis (NGU) patients (Johnston and McEwin, 1945; Harkness, 1945, 1950; Williams, 1946; Harkness and Henderson-Begg, 1948). Pleuropneumonialike organisms (PPLO) were frequently recovered in culture from these NGU patients ...

Shepard (1956) and Shepard, Alexander, Lunceford, and Campbell (1964) reported the isolation from men with non-gonococcal urethritis of a species of mycoplasma which formed very small colonies on culture. The organisms were isolated from 86 per cent. of 79 men in the first study and from 51 per cent. of 64 men in the second. This organism was subsequently called T strain mycoplasma. Ford, Rasmu...

In the last two decades, the number of new cases of type 2 diabetes mellitus (T2DM) among U.S. adolescents has increased (Fagot-Campagna et al., 2000; SEARCH Study Group, 2006), which may be related to the lack of health-promoting behaviors, such as a balanced diet and adequate physical exercise. This descriptive correlational study examined the relationship between perceived risk for T2DM, die...

The 3D cube figures used by Shepard and Metzler [Shepard, R. N., & Metzler, J. (1971). Mental rotation of three-dimensional objects. Science, 171, 701-703] have been applied in a broad range of studies on mental rotation. This note provides a brief background on these figures, their general use in cognitive psychology and their role in studying spatial behavior. In particular, it is pointed out...

The partition of unity is an essential ingredient for meshless methods named by GFEM, PUFEM (partition of unity FEM), XFEM(extended FEM), RKPM(reproducing kernel particle method), RPPM(reproducing polynomial particle method), the method of clouds in the literature. There are two popular choices for partition of unity: a piecewise linear FEM mesh and the Shepard-type partition of unity. However,...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...

Sam Shepard is one of the foremost living American Playwrights. He has always been concerned with the problem of identity, specifically the fragmented identity of man living in the postmodern era. Such characterization is evident in his plays: True West, Fool for Love, and A Lie of the Mind. Thus, the present article is to demonstrate the fragmented identity of Lee and Austin, Eddie and May, an...

It may be hard, now that Mycobacterium leprae is just another entry in the large catalogue of pathogens whose DNA sequence is known and leprosy is just another treatable bacterial disease, to understand the excitement generated by the mouse footpad model when it was introduced. It is, after all, not obviously exciting: 10,000 bacilli are injected into the hind footpad of a normal mouse. This is...
