Human Sexuality Programs in Catholic Secondary Schools in the 80\u27s
Human sexuality programs, or sex education programs, have been a controversial issue for many years. The purpose of this study was to assess the effectiveness of human sexuality programs within Catholic secondary schools. This study investigated the effect of comprehensive or non-comprehensive sexuality programs upon students\u27 Positive Sexual Attitudes, awareness of Catholic Church Teachings, integration of Catholic Church Values, integration of current Social Values, and Biological Knowledge. Comprehensive human sexuality programs were defined as those containing three or more full semesters of classes related to sex and sexuality. Non-comprehensive human sexuality programs were defined as those containing less than two full semesters of such courses. The research study took place in four Roman Catholic dioceses in the State of California. Twelfth grade female and male students participated in the study and the sample population was established at 1,555. Several survey instruments were developed to test six hypotheses. A quantitative methodology was used in order to present the survey instrument data in a clear and concise manner. The demographic profile supplied independent variables, such as sex and religious influence upon behavior, for additional data analysis. Analytical results showed that only in the areas of Positive Sexual Attitudes and Biological Knowledge were comprehensive human sexuality programs significantly different from non-comprehensive sexuality programs. Higher scores for females over males were seen in five of the hypotheses. In the hypothesis concerning Social Values, males scored higher. Significant differences were noted in religious influence upon behavior in Catholic Church Teachings, Catholic Church Values, and current Social Values
Mechanical magnetometry of Cobalt nanospheres deposited by focused electron beam at the tip of ultra-soft cantilevers
Using focused-electron-beam-induced deposition, Cobalt magnetic nanospheres
with diameter ranging between 100 nm and 300 nm are grown at the tip of
ultra-soft cantilevers. By monitoring the mechanical resonance frequency of the
cantilever as a function of the applied magnetic field, the hysteresis curve of
these individual nanospheres are measured. This enables to evaluate their
saturation magnetization, found to be around 430 emu/cm^3 independently of the
size of the particle, and to infer that the magnetic vortex state is the
equilibrium configuration of these nanospheres at remanence
Women, Power, and Anger: A Phenomenological Investigation of Female Mayors
The following is a phenomenological study of the role anger in women's lives. Though much research on women's anger explores the pathological side of anger and attempts to control the emotion, this research takes a positive approach to the emotion seeing it as a motivator for change and status enhancement. The researcher interviewed six female mayors from a Midwestern state about their experience and expression of anger while in public and private settings. The study participants expressed discomfort with anger and its expression. Because the women perceived that they did not have as much power as their councils, women in this study rarely expressed their anger in public while in their role as mayors. The women described containment of anger while in public, holding their anger until later when they could utilize social supports or cathartic release. In private, the participants in the study indicated use of anger with family or co-workers. The current research contributes to the growing literature concerningSchool of Teaching and Curriculum Leadershi

Light-induced cell damage in live-cell super-resolution microscopy
Super-resolution microscopy can unravel previously hidden details of cellular structures but requires high irradiation intensities to use the limited photon budget efficiently. Such high photon densities are likely to induce cellular damage in live-cell experiments. We applied single-molecule localization microscopy conditions and tested the influence of irradiation intensity, illumination-mode, wavelength, light-dose, temperature and fluorescence labeling on the survival probability of different cell lines 20-24 hours after irradiation. In addition, we measured the microtubule growth speed after irradiation. The photo-sensitivity is dramatically increased at lower irradiation wavelength. We observed fixation, plasma membrane permeabilization and cytoskeleton destruction upon irradiation with shorter wavelengths. While cells stand light intensities of ~1 kW cm(-2) at 640 nm for several minutes, the maximum dose at 405 nm is only ~50 J cm(-2), emphasizing red fluorophores for live-cell localization microscopy. We also present strategies to minimize phototoxic factors and maximize the cells ability to cope with higher irradiation intensities
Effect of Hetrovalent substitution at Mn site on the Magnetic and Transport Properties of LaSrMnO
Magnetic and transport properties of Ti substituted
LaSrMnO are drastically affected with a change in
preparation conditions. Low temperature infra-red absorption measurements
reveal that this is perhaps due to inhomogeniety in substitution of Ti
on Mn sites. It is found that, in the high temperature annealed samples, the
substitution of Ti supresses the double exchange interaction due to the
formation of Mn-O-Ti chains. While in the low temperature
annealed case substitution of Ti causes formation of isolated ferromagnetic
clusters linked to each other by a variable range hopping polaron.Comment: 11 pages, 8 figures, accepted in J. Magn. Magn. Magn. Mate
Clinical Research: Evaluation of Healing Touch\u27s Effect on Coronary Artery Bypass Grafting (CABG) Recovery, a Randomized Study
This study is assessing the efficacy of Healing Touch on patients receiving Coronary Artery Bypass Grafting at St. Cloud Hospital. A single previous research study determined Healing Touch, when added to standard nursing care, can significantly reduce anxiety and length of stay in patients undergoing CABG procedures.https://digitalcommons.centracare.com/nursing_posters/1087/thumbnail.jp
Will Offshore Energy Face “Fair Winds and Following Seas”?: Understanding the Factors Influencing Offshore Wind Acceptance
Most offshore energy studies have focused on measuring or explaining people’s perceptions of, and reactions to, specific installations. However, there are two different types of acceptance: one surrounds the siting of projects while the other surrounds a more general acceptance of offshore energy. Understanding what drives this second type of acceptance is important as governments have implemented new financial incentives and policies to support renewable energy development; however, citizens and government officials may be increasingly opposed to some of these support mechanisms. Our paper fills a void in the literature by using regression approaches to better understand how people’s evaluations of the benefits and costs of offshore wind impact their level of general acceptance for offshore wind, while controlling for other factors (e.g., demographics). This analysis should help policy makers, and individuals attempting to educate the general public about renewable energy, to better understand the important factors influencing people’s support or opposition to offshore wind energy initiatives
Investigating Cellular Structures at the Nanoscale with Organic Fluorophores
Super-resolution fluorescence imaging can provide insights into cellular structure and organization with a spatial resolution approaching virtually electron microscopy. Among all the different super-resolution methods single-molecule-based localization microscopy could play an exceptional role in the future because it can provide quantitative information, for example, the absolute number of biomolecules interacting in space and time. Here, small organic fluorophores are a decisive factor because they exhibit high fluorescence quantum yields and photostabilities, thus enabling their localization with nanometer precision. Besides past progress, problems with high-density and specific labeling, especially in living cells, and the lack of suited standards and long-term continuous imaging methods with minimal photodamage render the exploitation of the full potential of the method currently challenging
