Can Holistic Wellness Predict Teacher Effectiveness?

Harwell, Dana Rolison 05 August 2006 (has links)
Wellness literature reported that the current focus on academic achievement and high-stakes testing has sacrificed wellness in students, and ?there is a strong need and a public outcry to promote wellness in public schools? (Myers & Sweeney, 2005a, p. 228). Also, ?the promotion of schoolwide well-being will enrich the academic experience of students and families. In addition, school staff members who are aware and knowledgeable of wellness concepts may be more likely to apply healthy strategies in the curriculum and throughout the school? (Myers & Sweeney, p. 232). Effective teacher research supported the Student Teacher Assessment Instrument as a viable measure of teacher effectiveness. The purpose of this research was to determine whether holistic wellness as defined by creative self, coping self, social self, essential self, and physical self as measured by the 5F-Wel can be used to predict teacher effectiveness as measured by the STAI. The research question proposed for this study was: Is there a relationship between wellness as measured by the Five Factor Wellness Inventory and effective teaching as measured by the STAI? The research design was correlational. A convenience sample of voluntary participants among the 54 teacher interns during the spring 2006 semester from Mississippi State University-Meridian campus was used. The predictor variables were the second order factor scores on the 5F-Wel. These factors are creative self, coping self, social self, essential self, and physical self. The dependent variable was the overall formative score on the STAI. The results obtained show the predictor variables included in the multiple linear regression analysis did not predict teacher effectiveness as measured by the STAI at an accuracy greater than chance. A statistically significant relationship between the predictor variables and dependent variable was not found. Specifically, wellness as measured by the second order factors on the 5F-Wel did not predict teacher effectiveness as measured by the STAI in this study. Recommendations included: (a) using similar methodology in other studies and (b) replicating the study with future cohorts of student interns from Mississippi State University-Meridian Campus.

Electrons in 5f Systems

Le, Duc-Anh 11 October 2010 (has links)
The localized/delocalized duality of 5f electrons plays an important role in understanding the complex physics of actinides. Band-structure calculations based on the ad hoc assumption that 5f electrons are simultaneously localized and delocalized explained the observed dHvA experiments very well. This ad hoc assumption also gives the correct equilibrium volume for delta-Pu. Experimentally, the duality of 5f electrons is observed by inelastic neutron scattering experiments, or by soft X-ray angle-resolved photoelectron spectroscopy. It is worth recalling that the origin of partial localization in the 3d and 5f systems is quite different. In compounds with 3d electrons, the large crystalline electric field set up by the surrounding environment of transition metal ions plays a major role. On the other hand, in 5f systems, the Hund's rule correlations play the key role whilst the crystalline electric field is less important. In this thesis we have studied the effect of intra-atomic correlations on anisotropies in hopping matrix elements of different 5f orbitals. For that purpose, we used the effective model that includes on-site interactions that are responsible for Hund's rules and effective hopping terms that result from the hybridization of different 5f orbitals with the environment. Two different approximations, namely, rotationally invariant slave-boson mean-field (RISBMF) and infinite time-evolving block decimation (iTEBD), have been used to investigate the ground-state properties of the Hamiltonian. We have demonstrated that Hund's rule correlations enhance strongly anisotropies in hopping matrix elements. For a certain range of 5f bandwidth parameters this effect may result in a complete suppression of hopping processes for some of 5f orbitals, i.e., the system is in a partially localized phase. Within the RISBMF method, we calculated the ground-state properties and the phase diagram of the system. The suppression of hopping processes in some of 5f orbitals due to Hund's rule correlations can be seen through orbital-dependent quasiparticle weights. In a mean-field theory, a quasiparticle weight of zero for an orbital means a complete suppression of hopping processes in this orbital. Thus, quasiparticle weights and occupation numbers were used to classify partially localized phases. In the calculated phase diagram we obtain four partially localized phases that can be separated into two different sets. In the first set electrons in two orbitals are localized. In the second, electrons in one orbital are localized. The difference between the two sets is not simply the number of localized orbitals but the mechanism for the partial localization. For the first set, the Hund's rule mechanism applies: only those 5f electrons that enable the remaining ones to form a Hund's rule state will delocalize. This mechanism requires to have at least two localized orbitals, therefore it is definitely not applicable to those phases with only one localized orbital. For the second set, a situation similar to a single-band Mott-Hubbard transition applies. The direct on-site Coulomb interaction between jz and -jz electrons plays the key role for understanding the partial localization transition. In order to assess the validity of the RISBMF results we have used the iTEBD method to calculate the ground-state properties of a 1D system. Qualitatively, the two approaches agree with each other. However, we found an area where the RISBMF yields an artificial ground-state. Note that the mean-field method is worst for a 1D system. Therefore one shoud not judge from it the quality of the RISBMF method for the more general case.

Wellness in student affairs: An exploration of the profession and its practitioners.

Marling, Janet L. Trepka 05 1900 (has links)
This mixed design study surveyed members of the National Association of Student Personnel Administrators (NASPA) to determine the baseline for wellness among student affairs administrators and within the profession. In addition to describing the wellness levels of the administrators and comparing them to the wellness of the general population, the study explored how wellness is represented within the student affairs profession, as reflected in the literature and practice. Student affairs administrators' wellness was assessed utilizing the Five Factor Wel Wellness Inventory (Myers & Sweeney, 2004). Collectively, the administrators posted "well" scores on the six factors utilized in the study and scored higher than the norms reported for the 5F-Wel general population. However, there was a broad range of actual scores across individuals indicating that not everyone can be considered to be maintaining a well-balanced lifestyle. The administrators' wellness was not affected by their length of time in the student affairs profession but was negatively associated with the number of hours they worked per week. The administrators possessed a holistic view of wellness and could articulate the behaviors and conditions associated with achieving, and failing to achieve, balance. However, reported engagement in certain wellness behaviors (e.g., physical activity and healthy eating) was not always reflected in the 5F-Wel scores. Additionally, the administrators noted a lack of focus on wellness issues in the student affairs literature, professional organizations, and most pointedly, in graduate preparation programs. The study creates a context for individual exploration of balance given the "norms" of the profession and instigates dialog focused on building healthy workplaces that facilitate positive role modeling experiences for students and staff. Recommendations for practitioners, graduate program faculty, and the profession aim to maximize personal wellness, create balanced professionals, and facilitate congruence between the student affairs profession's espoused values and wellness philosophy and the enculturation of professionals into this ideology.

Extracts of submerged cultures also highlighted in terms of antibacterial activity, where the chloroform extract of the submerged culture&nbsp; <em>C. comatus</em>&nbsp; showed as the most potent. Also, the ethanolic extract of the submerged culture of<em>&nbsp; C. comatus</em>&nbsp; was found to be most relevant in anti-acetylcholinesterase activity&nbsp; compared with&nbsp; the conventional donepezil drug.
