Histomorphological Variation in the Appendicular Skeleton
Densities of osteons and osteon fragments at the midshafts of the femur, tibia, fibula, humerus, radius, ulna and clavicle are examined in a sample of contemporary human males and females (n = 39; 23 female, 16 male), with comparative data derived from one specimen each of Gallus gallus and Felis silvestris catus.Results demonstrate that there are significant differences in mean complete and fragmentary osteon densities among bones and between th…
Quantitative non-destructive analysis of metals in artefacts
Work on corroded lead-iron shot from the Mary Rose led to the development of two non-destructive techniques which can be employed to determine quantitatively the amounts of metals in a bimetallic artefact. The methods are described, equations produced and experiments conducted to authenticate the data produced. Both methods are relatively simple and need little equipment
Histomorphological and geometric properties of human femoral cortex in individuals over 50
Cortical area, area moment of inertia, and polar moment of inertia were determined from the midshafts of a series of 62 femurs (34 female and 28 male) from a U. S. white population, ages 51–95. The density of osteons and osteon fragments (per mm 2 ) was also determined. Neither osteon nor osteon fragment density was significantly correlated with age. These variables were correlated, however, with normalized cortical and endosteal areas, normalize…
The Impact of Racial Variation on Human Engineering Design Criteria
Critical Issues Facing Society
We describe herein an introductory STS course, designed for large numbers of students, which uses a large number of faculty instructors. Its content and style has evolved continuously for 20 years in a major research university and been adapted for use in small two-year and four-year campuses
A revised method of age determination using the os pubis, with a review and tests of accuracy of other current methods of pubic symphyseal aging
All current standardized methods of age determination using the os pubis were tested by blind assessment of a skeletal sample with documented ages (from the Todd collection; N = 96). No demographic data (sex, age, race, age composition) were known to the assessors prior to completion of the test. Results showed the Todd method to be more reliable than more recent component techniques and that all systems tended to underage. Therefore, modificatio…
Radiographic changes in the clavicle and proximal femur and their use in the determination of skeletal age at death
Visually seriated radiographs of the proximal femur, proximal humerus, clavicle, and calcaneus from 130 individuals from the Hamann‐Todd collection were examined as indicators of skeletal age at death. The clavicle demonstrated the most consistent relationship to age in both sexes. The same radiographs were also seriated by size‐normalized optical density as a means of establishing relative radiolucency. In this context, visual seriation proved s…

The Demand for Security― an Educational and Military Problem
Citizenship Education and the Colleges
One of the happier educational products of the war was the widespread self-examination it encouraged among American colleges. With the wartime slump in enrollments, those members of the faculty who remained on the campus were commonly given the task of planning the postwar educational programs of their respective institutions. We are now in that postwar period, and much of this admirable effort has been dropped to grapple with the heavy enrollmen…
The Universities and the Public Service
The current slump in the number of university students taking courses in public administration suggests that this is a good time to reflect on what form education for the public service should take after the war. It is highly probable that many university students will again undertake to prepare themselves for jobs and careers in government, despite an inevitable reduction in the number of federal employees. Educational assistance to veterans may…
The Relation of Budgeting to Program Planning
cent years toward advancing the theory and practice of executive budgeting. The now common requirement that departments and bureaus submit budget estimates to legislative bodies only through, or with the approval of, the chief executive has become the principal tool of administrative management in the hands of mayors, city managers, governors, and the President. At the same time, the budget has acquired increasing importance as an over-all plan o…
