The Accessibility of American Catholic Secondary Schools to the Various Socioeconomic Classes of Catholic Families

The purpose of this study was to discern which socioeconomic classes are represented in Catholic high school populations across the United States. In addition, the study sought to discover the motivations of those families whose children were currently enrolled in American Catholic high schools. Also explored were the reasons why Catholic families who have sent their child or children to Catholic elementary schools were electing not to continue Catholic education at the secondary level. Because financial aid availability has risen along with tuition (Tracy, 2001), this investigation included the extent to which such financial aid was considered by Catholic families, as well as the perceptions of Catholic families as to its availability at the secondary level. As tuition rates rise at a higher level than the cost of living and averages wage increases, this study additionally examined the extent to which the assertion (Baker & Riordan, 1998, 1999; Riordan, 2000) that American Catholic high schools were becoming more elitist is true. The Catholic Church’s statements as to the accessibility of Catholic education to all social classes provided a framework throughout the investigation

Studies on Zea coleoptile cell wall [beta]-D-glucanases and their native substrates

In vitro autolytic reactions in Zea mays (hybrid B73 x Mo17) coleoptile cell walls were investigated. Of interest were the polysaccharides which served as substrates, characteristics of the participating enzymes and the mechanism of hydrolysis;During cell wall autolytic reactions, 85 to 90% of the hemicellulosic (beta)-D-glucan, which constituted as much as 117 (mu)g per mg cell wall dry weight, was liberated from cell wall in the form of polymeric and monomeric products. Enzymolysis of the polymeric products with a purified bacterial glucanase specific for mixed-linkage glucans confirmed that (beta)-D-glucan served as the primary substrate for autolytic reactions. Small quantities of galactose were observed; however, other major wall components consisting of xylose and arabinose were unaffected during autolytic reactions;The autolytic enzymes were found to be tenaciously associated with isolated cell wall. Pretreatment of cell wall with detergents and ionic strength failed to significantly affect their autolytic potential. The use of high ionic strength (3 M) facilitated the dissociation of the enzyme-cell wall complex, and reconstitution studies confirmed that the salt-solubilized enzymes included the autolytic enzymes;Purification of the cell wall enzymes disclosed both endo- and exo-glucanases proteins. The former, apparently an endo-(beta)-1,3-glucanase, had a molecular weight of 26,000 daltons and exhibited a pH optimum of 5.5. This enzyme was apparently responsible for initiating the autolytic dissolution of wall glucan. An exo-(beta)-1,3-glucanase with a molecular weight of 60,000 daltons was further purified using a cation-exchange procedure. The enzyme was strongly inhibited by inorganic mercurials and along with an exocellulase appeared to be responsible for the hydrolysis of endo-enzyme-resistant polymeric glucan generated by the endoenzyme. It is believed that the capacity of the endoenzyme to degrade (beta)-D-glucan was dependent on the presence in the glucan of linkage sequences with regions of contiguous (beta),1-3 glucosyl bonds;The results of studies employing mercuric chloride, nojirimycin and glucono-(delta)-lactone suggested that (beta)-glucosidase activity was not required for glucan hydrolysis;Cell wall glucanases have frequently been implicated as having some role in auxin-induced growth. The glucanases participating in autolytic reactions did not appear to be under the direct control of auxin

Theses on Ecumenical Truth and Heresy

Out of love and zeal for both truth and unity, the following theses are presented to my beloved colleagues in the Southern California District of The Lutheran Church-Missouri Synod as a constructive contribution to the current debate on altar and pulpit fellowship. They do not represent an official policy, but are only a personal, unofficial opinion offered for exploratory discussion. They reflect the hernial stance of one who lives in the tension of obedience to Jesus Christ while simultaneously remaining a responsible member of a changing synod and a changing world
