Wenatchee School District Middle School Athletic Program: A New Concept in Middle Level Sports

The Wenatchee School District in Wenatchee, Washington instituted a new middle school athletic program in response to the construction of a new middle school. The new dynamics in the district provided the opportunity to reassess the goals, objectives, and philosophy of their middle school athletic program. Visitations to several of these programs and interviews with many of the administrators, coaches, teachers, and student athletes revealed many of the strengths and weaknesses of the various programs. This information was presented to Wenatchee School District middle level administrators, community leaders, and middle school staff in order to develop the criteria that met with Wenatchee\u27s philosophical needs. Four athletic model proposals were presented to the school board. An in-district model of intra-scholastic competition was adopted. Five sports seasons and two traditional sport placement switches were implemented. Increased participation, appropriate competition, and program continuity with the high school were a few of the program objectives

A history of naturalization in Crawford County, Kansas

America, since its discovery, has been a haven for the oppressed of other lands. This continent has offered to millions of immigrants from the old world new economic and social opportunities, a wider freedom, and a greater chance for personal development. In return the newcomers have woven their ideas and ideals into the fabric of a great nation. The first immigrants gave much to the country. They were home seekers ready and willing to cooperate with the native born to make this an enlightened country. The settlers of Crawford County, Kansas have proved to be no exception. Many interesting problems have arisen, however, concerning the naturalization and Americanization of the aliens within the country

Geometrical characterization of textures consisting of two or three discrete colorings

Geometrical characterization for discretized contrast textures is realized by computing the Gaussian and mean curvatures relative to the central pixel of a clique and four neighboring pixels, these four neighbors either being first or second order neighbors. Practical formulae for computing these curvatures are presented. Curvatures based on the central pixel depend upon the brightness configuration of the clique pixels. Therefore the cliques are classified into classes by configuration of pixel contrast or coloring. To look at the textures formed by geometrically classified cliques, we create several textures using overlapping tiling of cliques belonging to a single curvature class. Several examples of hyperbolic textures, consisting of repeated hyperbolic cliques surrounded by non-hyperbolic cliques, are presented with the nonhyperbolic textures. We also introduce a system of 81 rotationally and brightness shift invariant geo-cliques that have shared curvatures and show that histograms of these 81 geo-cliques seem to be able to distinguish isotrigon textures

Spatial biases and computational constraints on the encoding of complex local image structure

The decomposition of visual scenes into elements described by orientation and spatial frequency is well documented in the early cortical visual system. How such 2nd-order elements are sewn together to create perceptual objects such as corners and intersections remains relatively unexplored. The current study combines information theory with structured deterministic patterns to gain insight into how complex (higher-order) image features are encoded. To more fully probe these mechanisms, many subjects (N = 24) and stimuli were employed. The detection of complex image structure was studied under conditions of learning and attentive versus preattentive visual scrutiny. Strong correlations (R2 > 0.8, P < 0.0001) were found between a particular family of spatially biased measures of image information and human sensitivity to a large range of visual structures. The results point to computational and spatial limitations of such encoding. Of the extremely large set of complex spatial interactions that are possible, the small subset perceivable by humans were found to be dominated by those occurring along sets of one or more narrow parallel lines. Within such spatial domains, the number of pieces of visual information (pixel values) that may be simultaneously considered is limited to a maximum of 10 points. Learning and processes involved in attentive scrutiny do little if anything to increase the dimensionality of this system

Cup products in the etale cohomology of number fields

This paper concerns cup product pairings in \'etale cohomology related to work of M. Kim and of W. McCallum and R. Sharifi. We will show that by considering Ext groups rather than cohomology groups, one arrives at a pairing which combines invariants defined by Kim with a pairing defined by McCallum and Sharifi. We also prove a formula for Kim's invariant in terms of Artin maps in the case of cyclic unramified Kummer extensions. One consequence is that for all $n > 1$, there are infinitely many number fields $F$ over which there are both trivial and non-trivial Kim invariants associated to cyclic groups of order $n$.Comment: 21 pages; in version 3 we changed the title of the paper and we restructured the pape
