Spatial correlations are replaced by ordinary correlations by projecting the two-dimensional coordinates of a map onto a single axis making angle θ with the horizontal (east-west) axis. This calculation permits the use of exact test statistics. Moreover, the correlations can be plotted in polar coordinate form and the significance of the maximum correlation can be tested. The plot is a useful aid in assessing the reasonableness of the isotropy assumption.  相似文献

Analysis of survey data from 291 state legislative committee chairs suggests that professionalization has important gender implications not previously explored. Legislatures are gendered in the sense that culturally masculine and feminine committee management styles are more at home in some legislatures than in others. "Citizen" legislatures seem to be more hospitable to "feminine" behaviors of inclusion and a motivation focused on people-oriented concerns. Professionalized legislatures–promoted in large part on the basis of a masculine vocabulary of independence, rationality, expertise, and competition with the executive–discourage inclusive or collegial committee strategies and public-minded motives. Professional legislatures may be positive environments in which to nurture policy leadership, but their committee leaders eschew public participation.  相似文献

Research into geography provision in primary initial teacher education [ITE] courses in the United Kingdom and worldwide is very limited. England educates pre-service primary teachers of 5–11 year olds to be “generalists” who teach the full range of curriculum subjects, including geography. This article identifies that the provision of teaching time for geography is low and declining in England’s primary ITE courses. It presents a picture which may not seem dissimilar in other parts of the world. With only about half of pre-service primary teachers in England having studied geography after age 14, their subject knowledge appears weak. University-based ITE subject sessions rarely extend beyond introducing them to England’s primary geography requirements and to some approaches to teaching geography. Prospective primary teachers observe and teach limited, if any, geography in primary schools. Developing their geographical understanding and teaching capability is highly challenging for tutors. There are concerns that the current situation may well decline further. Encouragement exists to develop geography provision in primary ITE but the opportunities to achieve this appear increasingly constrained as the pre-service environment moves from university-led to school-led provision. International comparative research is essential to understand better pre-service primary teachers’ learning to teach geography.  相似文献
