The purposes of this descriptive study were to determine the reasons for which Anglo and Hispanic parents/guardians send their children to a Catholic high school in the southwestern United States and to investigate the effect of specific demographic elements upon the parents'/guardians' reasons. These elements were sex, age, and ethnicity of student; age, sex, ethnicity, religion, educational level, and social-economic status of parents/guardians; and marital status, family school affiliation, and family configuration, and family mobility. A modified Delphi procedure with two questionnaires was used to both identify the reasons and to investigate the possible effects of the demographic elements. A RVAX computer with SPSSX was used to apply measures of central tendency, factor analysis, and ANOVA to the data. The study revealed that the main reasons for this Catholic school choice were academics and discipline/environment. The secondary reasons were teachers/students, size and programs, and religious instruction and atmosphere. The two remaining reasons were dissatisfaction with public schools and family tradition. The study indicated that the interaction of age, sex, and ethnicity of students did significantly influence the evaluations of discipline/environment, religious instruction and atmosphere, and family tradition. In addition, the evaluations of the seven factors were significantly influenced by various combinations of family mobility, economic status, family configuration, marital status, religion, educational level, and ethnicity, age, and sex of parents/guardians. The study suggested that although parents/guardians in 1986 agree with those in a 1974 study that academics is important, they place much less importance upon religion. Other major findings suggested that the values of specific categories of parents/guardians cannot be accurately predicted and that it should not be assumed that Anglo and Hispanic students are sent to a Catholic school for different reasons. Finally, the study suggested that academics and discipline/environment, the main reasons for which parents/guardians make the Catholic school choice, should be a concern of all schools, whether they are parochial, private, or public.

Oriented archaeomagnetic samples were collected from 158 in situ features at 33 sites in the southwestern U.S. Seventy-three independently dated features were used for analysis of secular variation. A moving-window smoothing technique with outlier rejection was developed to objectively compute a virtual geomagnetic pole (VGP) path. Weighted Fisher statistics, accounting for errors in both dating and archaeomagnetic direction, were used to compute a mean VGP and standard error (A95) within each window of time. The VGP moves from 86°N, 83°E at A.D. 750 to 74°N, 192°E at A.D. 1075, and then to 85°N, 236°E at A.D. 1425. Secular variation of the VGP ranges from .00423-.350°/yr with a median of .0359°/yr. The A95s for the VGP curve range from 1.33-5.28°. Archaeomagnetic declinations and inclinations in Tucson range from 346-359°E and 47-60°. The close agreement with a similarly constructed VGP curve for Arkansas implies a small nondipole field in North America between A.D. 1150-1450. The VGP curve is significantly different from that of R. L. DuBois. Three case histories of archaeomagnetic dating suggest the validity of the new curve. The Thellier-Thellier paleointensity experiment was performed on 187 specimens from 77 potsherds. A significant magnetic fabric anisotropy, typically 30%, was found. Using an easy-plane model of magnetization, the anisotropy correction systematically increased the paleointensities by 5%. Paleointensities were interpreted for 127 samples from 54 sherds. All ceramics were independently dated and used along with other results to construct a virtual axial dipole moment (VADM) curve. A moving-window smoother using weighted statistics within each interval of time and incorporating outlier analysis was used. The Southwestern VADM at 300 B.C. is 14 x 10('22)Am('2), decreases to 8.6 x 10²²Am² at A.D. 800, and increases to 12.9 x 10²²Am² at A.D. 1500. Paleointensities from Hohokam ceramics compare favorably with paleointensities from other Southwestern ceramics, regardless of whether the long Hohokam chronology beginning at 300 B.C. or the short chronology beginning at A.D. 500 are used. There is also reasonable agreement between the Southwest and Mesoamerican VADM records.
