Ground-water resources of Collier County, Florida

The Biscayne Aquifer is the principal source of water for the heavily populated area in the vicinity of West Palm Beach and Miami. The publication of this data is timely and will assist in the intelligent development of the water resources of the area.The report recognizes two major aquifers as the source of ground water in Collier County. The lower aquifer is highly mineralized, but contains usable water, and the more shallow aquifer is the source of large supplies, which are utilized by municipalities and domestic users. Adequate supplies of fresh water are present in the Naples area and by proper planning, these can be developed in an orderly manner and salt water encroachment can be prevented. (PDF has 99 pages

Academic Performance among Student Library Employees: How Library Employment Impacts Grade Point Average and Perception of Success

The study of college student employment and its effects on retention, academics, and student satisfaction is not new and yet has come to varying conclusions; also, very little has been reviewed on what impact a student’s place of employment may have on their academics. This research examines student employees at a college library and how that specific type of employment has impacted the academic success of those employees. The study used a combination of data, comparing their cumulative grade point average with survey results asking about their perception of the effect library employment had on their academics. The overwhelming majority of students felt that library employment had a positive impact on their academics and this perception was confirmed by their collective, average GPAs when compared to that of their peers. This research expands the knowledge not only in the potential impact of place on academics but also in how college libraries perceive their impact upon student employees and the benefits of such employment

The Business of Museums and the Engagement of 21st Century Audiences

Within the sub-theme of Collaboration, Partnerships, and Mergers – the author will create an engaging discussion with attendees on how the of business of museums lends itself to building collaborative and viable business partnerships which can be beneficial both in terms of revenue and audience engagement. A second element will examine through case studies how organizations such as the Oxford University Museum Partnership, The Lightbox Museum and Gallery as well as the British Museum and Museum of London retool and refocus their commercial interests to build sustainable partnerships and mergers with non-museum sector organizations to expand their retail and enterprising activities. Attendees and participants will gain an insight into these trends and methods currently being used by both large museum and small independent museums in the UK to grow their audiences through none traditional methods. Similarly, the author will demonstrate how non-traditional enterprising approaches to stewardship and education can demonstrate the public value of museums in an age when limited funding and competition for resources require museums to become more creative and collaborative outside their traditional roles, whilst continuing to engage and capitalize on the growing sophistication of 21st century audiences

Spin Chains as Perfect Quantum State Mirrors

Quantum information transfer is an important part of quantum information processing. Several proposals for quantum information transfer along linear arrays of nearest-neighbor coupled qubits or spins were made recently. Perfect transfer was shown to exist in two models with specifically designed strongly inhomogeneous couplings. We show that perfect transfer occurs in an entire class of chains, including systems whose nearest-neighbor couplings vary only weakly along the chain. The key to these observations is the Jordan-Wigner mapping of spins to noninteracting lattice fermions which display perfectly periodic dynamics if the single-particle energy spectrum is appropriate. After a half-period of that dynamics any state is transformed into its mirror image with respect to the center of the chain. The absence of fermion interactions preserves these features at arbitrary temperature and allows for the transfer of nontrivially entangled states of several spins or qubits.Comment: Abstract extended, introduction shortened, some clarifications in the text, one new reference.

hagis, an R Package Resource for Pathotype Analysis of Phytophthora sojae Populations Causing Stem and Root Rot of Soybean

Phytophthora sojae is a significant pathogen of soybean worldwide. Pathotype surveys for Phytophthora sojae are conducted to monitor resistance gene efficacy and determine if new resistance genes are needed. Valuable measurements for pathotype analysis include the distribution of susceptible reactions, pathotype complexity, pathotype frequency, and diversity indices for pathotype distributions. Previously the Habgood-Gilmour Spreadsheet (HaGiS), written in Microsoft Excel, was used for data analysis. However, the growing popularity of the R programming language in plant pathology and desire for reproducible research made HaGiS a prime candidate for conversion into an R package. Here we report on the development and use of an R package, hagis, that can be used to produce all outputs from the HaGiS Excel sheet for P. sojae or other gene-for-gene pathosystem studies

Extension\u27s Role in the United States\u27 Campaign to Reduce Food Waste

Extension can play a role in the United States\u27 campaign to reduce consumer food waste by 2030. Food waste exists alongside food insecurity and affects individual households, agriculture, and the environment. Addressing food waste through a food systems approach requires involvement from Extension experts in family and consumer sciences, agriculture, environmental health, community development, policy, research, and education. Understanding the magnitude of and reasons for consumer food waste in the United States helps educators address this complex issue. By changing how people think about and manage food and food waste, Extension can have a significant impact on future generations

A Study of the Effects of an Improved Classroom Environment on Secondary Students\u27 Attitudes and academic Performance

An attempt will be made in this study to determine if a decorated, well-maintained biology classroom has any influence on the attitudes of students toward their classroom, school, subject and teacher. A twenty-item survey containing items which will measure each of the previously mentioned attitudes will be administered to a biology class which uses a decorated, well-maintained classroom. Another biology class taught by the same teacher will also be administered the same survey. However, this class is taught in a poorly-maintained, undecorated classroom. Both classes consist of students who were assigned to them in no particular fashion. An analysis will be made of the survey results to determine if there are any differences in the attitudes between the students in the decorated classroom and the undecorated classroom. The eighth, ninth and tenth grade first semester science grades of all of the students using these classrooms will also be compared to determine if their classroom environment has had any possible effect on their achievement in this subject. The problems being investigated can be stated as two questions: Can decorated, well-maintained classrooms in secondary schools produce a difference in student attitudes toward their classrooms, schools, subjects and teachers? Can they also produce a difference in academic achievement from these students
