A multivariate, theoretical model is developed and tested topredict household telephone ownership. Factors theorized topredict telephone ownership are 1) socio-economic status/resources,2) household composition, 3) cultural background, 4) attachments,includinga) community/mobility ties, b) civic/politicalties, c) group ties, d) personal ties, e) social and institutionalalienation, and of misanthropy, 5) counter-normative behavior,6) psychological well-being, and 7) physical well-being. Theanalysis, indicates that the socio-economic factor in generaland income in particular has the largest impact. All other factorsalso have significant, independent effects with the exceptionthat some, but not all, of the attachment factors and psychologicaland physical well-being are not related to telephone ownership.Overall, non-telephone households can be characterized as marginaloutsiders. 相似文献

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique,
instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study,
the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular
velocity relative to that segment’s ISA and verify that ISA theory is a valid tool to analyse segment rotation during the
golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective
ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore,
ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that
motion about the ISA is representative of joint motion. 相似文献

The use of online learning and other software-powered technologies is on the rise in the United States, encouraged financially and politically by governmental and commercial entities. Specifically, online courses are gaining ground in K–12 public schools, schools which often purchase from third-party providers. After a decade in the New York City Department of Education as an English teacher and schools official responsible for a large-scale online learning programme, the author asks the question: How does the use of software-powered technologies like online learning affect the teaching of literature? In pursuit of this question, the author draws on concept from the field of software studies while adapting qualitative methods from multimodal studies to examine precisely how the nature of software (and the ideologies of those who create and sell it) are subtly influencing the teaching of literature. 相似文献
