Motivational Patterns Of Enrollees In University-Based Executive And Professional Education Courses

The purpose of this paper is to begin an exploration into high-skills lifelong learning in the field of business and management, referred to as executive and professional education (EPE).  Several additional undertakings were necessary, including: discovering methods of valuing knowledge to a region, state or country, and establishing why participants in EPE programs enroll in them. To support this inquiry two research questions were developed, as follows:  1. What are the components of relevant EPE? 2. What motivates participants to take part in EPE? An exploratory case study was written exploring the intricacies of developing a successful EPE department.  This exploratory case study served as a basis for developing a survey, administered to participants in EPE to determine reasons for their participation.  This final survey was conducted in the classroom. The researchers believe that the findings and conclusions will be of value to practitioners involved in EPE, as well as to academics studying this area of business education.  This research exercise has assisted the researchers in being more effective in managing and developing EPE within their own university.  As professions and skills are made obsolete in the knowledge economy the need for continued high level lifelong learning becomes increasing important to the sustainability and viability of local, regional, state and national economies

ENVIRONMENTAL COMPLIANCE IN U.S. AGRICULTURAL POLICY: PAST PERFORMANCE AND FUTURE POTENTIAL

Since 1985, U.S. agricultural producers have been required to practice soil conservation on highly erodible cropland and conserve wetlands as a condition of farm program eligibility. This report discusses the general characteristics of compliance incentives, evaluates their effectiveness in reducing erosion in the program's current form, and explores the potential for expanding the compliance approach to address nutrient runoff from crop production. While soil erosion has, in fact, been reduced on land subject to Conservation Compliance, erosion is also down on land not subject to Conservation Compliance, indicating the influence of other factors. Analysis to isolate the influence of Conservation Compliance incentives from other factors suggests that about 25 percent of the decline in soil erosion between 1982 and 1997 can be attributed to Conservation Compliance. This report also finds that compliance incentives have likely deterred conversion of noncropped highly erodible land and wetland to cropland, and that a compliance approach could be used effectively to address nutrient runoff from crop production.conservation compliance, Sodbuster, Swampbuster, conservation policy, agri-environmental policy, nutrient management, buffer practices, Agricultural and Food Policy,

Constant-Rate-of-Strain and Controlled-Gradient Consolidation Testing

Controlled-gradient (CG), constant-rate-of-strain (CRS), and conventional incremental-loading (STD) consolidation testing are compared and evaluated. Undisturbed samples of tbree soils common to Kentucky were used in the testing program. Results of 15 CG, 14 CRS, and 32 STD consolidation tests are evaluated. Feasibility of the new test methods for routine testing is briefly discussed and recommendations are made for refinements in testing procedures

Levels of developmental assets and educational outcomes in young people in transitional living in Canada

"Developmental assets may be defined as significant relationships, skills, opportunities or values that protect young people in the presence of risk and promote their resilience. The purpose of this study was to discover whether high, medium, and low levels of developmental assets among transition-age young people in care were related to selected educational outcomes. If so, child welfare staff could potentially use their knowledge of a youth's level of assets to plan an appropriate level of educational assistance that would enable the youth to be more successful in his or her transition. The sample was composed of 567 young people (322 females and 245 males), aged 18-20 years, who were residing in a transitional living program in Ontario, Canada. The three levels of developmental assets were found to have statistically significant relationships with the seven educational outcomes examined that ranged between small-to-medium and strong in size. The educational outcomes consisted of the educational level in which the youth was currently enrolled, the highest educational level attained, average marks in school, participation in volunteering, employment, education or training, development of skills useful for employment, and adequacy of planning for the youth's education. The implications of the findings for rendering educational assistance to youths in particular need were discussed."

Im Mittelpunkt der vorliegenden Studie stand die Frage, ob hohe, mittlere und niedrige Entwicklungsressourcenniveaus betreuter Jugendlicher in der Übergangsphase mit ausgewählten Bildungserfolgen in Zusammenhang stehen. Ist dies der Fall, könnten Fachkräfte ihr Wissen um die Entwicklungsressourcen von Jugendlichen nutzen, um eine angemessene pädagogische Begleitung zu planen, die Jugendlichen hilft, den Übergang erfolgreicher zu gestalten. Die Stichprobe der Studie setzte sich aus 567 jungen Menschen (322 Mädchen und 245 Jungen) im Alter von 18-20 Jahren zusammen, die ein Übergangsprogramm in Ontario (Kanada) durchliefen. Die Ergebnisse der Untersuchung zeigen, dass die drei Niveaus in unterschiedlicher Stärke statistisch signifikant mit Erfolgen in den sieben untersuchten Bildungsbereichen korrelieren. Diese umfassten den momentan angestrebten Bildungsabschluss, den höchsten bereits erreichten Bildungsabschluss, den Notendurchschnitt in der Schule, Partizipation in freiwilligen Engagements, Arbeit/ Beschäftigung, Bildung oder Training, die Entwicklung beschäftigungsrelevanter Fähigkeiten, sowie zukunftsorientierte Bildungspläne. Abschließend werden Folgerungen für die Begleitung von Jugendlichen mit spezifischen Bedürfnissen diskutiert." (Autorenreferat

An experimental approach for investigating many-body phenomena in Rydberg-interacting quantum systems

Recent developments in the study of ultracold Rydberg gases demand an advanced level of experimental sophistication, in which high atomic and optical densities must be combined with excellent control of external fields and sensitive Rydberg atom detection. We describe a tailored experimental system used to produce and study Rydberg-interacting atoms excited from dense ultracold atomic gases. The experiment has been optimized for fast duty cycles using a high flux cold atom source and a three beam optical dipole trap. The latter enables tuning of the atomic density and temperature over several orders of magnitude, all the way to the Bose-Einstein condensation transition. An electrode structure surrounding the atoms allows for precise control over electric fields and single-particle sensitive field ionization detection of Rydberg atoms. We review two experiments which highlight the influence of strong Rydberg--Rydberg interactions on different many-body systems. First, the Rydberg blockade effect is used to pre-structure an atomic gas prior to its spontaneous evolution into an ultracold plasma. Second, hybrid states of photons and atoms called dark-state polaritons are studied. By looking at the statistical distribution of Rydberg excited atoms we reveal correlations between dark-state polaritons. These experiments will ultimately provide a deeper understanding of many-body phenomena in strongly-interacting regimes, including the study of strongly-coupled plasmas and interfaces between atoms and light at the quantum level.Comment: 14 pages, 11 figures; submitted to a special issue of 'Frontiers of Physics' dedicated to 'Quantum Foundation and Technology: Frontiers and Future

The theory of quantum levitators

We develop a unified theory for clocks and gravimeters using the interferences of multiple atomic waves put in levitation by traveling light pulses. Inspired by optical methods, we exhibit a propagation invariant, which enables to derive analytically the wave function of the sample scattering on the light pulse sequence. A complete characterization of the device sensitivity with respect to frequency or to acceleration measurements is obtained. These results agree with previous numerical simulations and confirm the conjecture of sensitivity improvement through multiple atomic wave interferences. A realistic experimental implementation for such clock architecture is discussed.Comment: 11 pages, 6 Figures. Minor typos corrected. Final versio

Effects of Mineral Nutrition on Components of Reproduction in Clarkia ungucilata

An experiment was conducted to determine the effects of nutritional level and flower location on factors related to flower, pollen, and ovule production, and to determine what developmental patterns would be modified to mediate any observed changes. Plants subjected to high nutrient levels developed larger leaves, more branches, more flowers on both the main stem and the branches, and opened their first flowers 6 days sooner than plants at lower levels of nutrients. Total flower number increased from 72.2 to 626.8 per plant, with most of the increase produced on the primary branches. The number of pollen grains in the entire androecium averaged 14,685, but significantly increased with higher nutrient levels and decreased with the stage of plant maturity (nodal position on the plant). The number of ovules also increased with nutrient level and decreased with maturity stage. Average ovule number decreased from about 129 in flowers at nodes produced early in the growth cycle to about 100 in flowers produced at later nodes. Despite highly significant plasticity in numbers of both pollen and ovules, the Pollen/Ovule Ratio (average 132.7) did not vary significantly with either nutrient level or plant maturity stage. Path analysis, which decomposes correlation coefficients into direct and indirect effects of factors influencing development, indicated that nutrient level had a very strong direct effect on the number of primary branches and on the number of primary-branch flowers, as well as very strong indirect effects on the latter. The primary-branch flowers directly determined over 67% of the total flower number, and indirectly determined about 24% jointly with secondary-branch flowers, and over 3% jointly with main-stem flowers. The direct effects of secondary-branch flowers and mainstem flowers were 3.8% and 0.3%, respectively. The relationship among components of yield is slightly additive. Direct determination of yield was 74.6% by the number of flowers per plant, 0.6% by the number of ovules per flower, 3.8% by the number of seeds per ovule, and 1.1 % by the weight per seed. The proportion of yield jointly determined by flower number and the developed seeds per ovule was 15.3%. It was concluded that allocation of resources increases to both male and female functions under conditions of high nutrient levels, and pollen/ovule ratios are consistent within a plant despite significant plasticity in numbers of pollen grains and ovules
