THE EFFECTS OF VERBAL AND NONVERBAL LEARNING STYLES ON STUDENT ATTITUDE, INTERPRETATION, AND INTEGRATION OF CONTENT WHEN READING GRAPHIC NOVELS

This study examined the effects of cognitive learning styles on how middle school students internalize and comprehend graphic novels. Using a qualitative approach the multiple case study examined student survey data, class assignments, interview responses, and focus group transcriptions in an effort to describe students’ perceptions of using graphic novels in a social-studies setting. After obtaining a convenience sample of 109 grade-eight students, an examination of the Otis-Lennon School Ability Test (OLSAT) scores took place. A purposeful sample of 11 students was drawn to construct three bounded case study groups representing varying verbal, nonverbal, and balanced learning styles as determined by the OLSAT. Upon the completion of all data collection and analysis a smaller sample of three students was chosen for a focus group. Emerging themes facilitated the generation of protocols for both interviews and focus groups and complemented the themes addressed in the PRGNS. Within and cross-case pattern analysis of data drawn from case study groups and the focus group yielded both similarities and differences. Verbal, nonverbal, and balanced subgroups believed there is potential depth and challenge to graphic novels, an engaging storyline is essential in maintaining focus while reading, prior knowledge impacts their ability to recognize symbols, and images provide focus and prevent mind wandering while reading. When preferences for reading genre were examined it was found that both the verbal and balanced subgroups had an overwhelming preference for fiction while the nonverbal subgroup preferred nonfiction. Finally, the reading attack strategies used by the subgroups differed based on their use of visuals with the reading. The verbal subgroup indicated reading the text of a textbook assignment first and later looking at visuals such as charts and pictures. Nonverbal participants discussed skimming the images and captions before reading the text, and the balanced group generally used bold headings like titles and subtitles to preview the content before reading text

Allocating water of the Nile River

Presented at River basin management to meet competing needs: proceedings from the USCID conference on shared rivers held on October 21-31, 1998 in Park City, Utah.The Egyptian philosophy of water use is that of an agrarian society even though perhaps only 50% of foodstuffs are produced domestically. The Egyptian Government is now implementing a plan of action that will spread water over vast new areas of the Western Desert and the Sinai. The objective is to transfer within 20 years as many as 7 million persons from the Nile Valley and the Delta to intensively irrigated areas of the Western Desert. This diversion of Nile River water is to be accomplished even as the nine upstream riparians are demanding more water. A paradigm shift is required. Those guiding irrigation development in the Western Desert must accept and embrace a model of mixed development based on: 1) the eventual minimization of irrigation of field crops, 2) the identification and filling of now dry water-table aquifers through diversion of excess river flows in wet years, and 3) exploitation of minerals and other important resources of the Western Desert to support the new communities. Clearly, during the initial stages of New Valley developments, the government needs to divert the entire excesses of wet year flows for over-irrigation of reclamation crops and the filling of pre-identified underground reservoirs. Integrated ground-water-surface-water systems should be established., successively along the path of development, to supply municipal and industrial water and for the irrigation of vegetables and fruit trees. A large component of the water required for creating shaded communities and wind breaks should be derived from reuse of treated wastewater effluents and the pumping of mildly brackish ground water. Thus, through the establishment of water-table aquifers along the route of development and the careful husbanding of the water resource, extensive settlements can be realized in the western Desert without substantial diminishment of the productive capacity of the agriculture of the Nile Valley and Delta. Sustainability of the colonization will depend equally on the exercise of care in protecting the fragile desert environment in every zone of development and the equitable collection of water user fees from the start of project operations

Transbasin water transfers

Presented at the 2001 USCID water management conference, Transbasin water transfers on June 27-30, 2001 in Denver, Colorado.It too often is the case that transbasin water transfer projects, worldwide, could be beneficial to an entire region and are well engineered and yet will never be constructed. This paper reviews social, political, financial, economic, and environmental factors that were dealt with in an effective manner by strong project advocates to realize the construction of the Laja Diguillin Irrigation Project. The Project is located in Region VIII of southern Chile. It stretches across nearly 100 kilometers of stream-dissected terrain to the south of the City of Chillan. The newly built primary transmission canal was designed to convey 1400 cusecs (40 cumecs) of diverted river flow from the Laja River, across six intermediate streams, to discharge some 28 miles (45 kilometers) distant into a pool created by a rubber dam on the Diguillin River. From this pool at the town of Bulnes the water is to be further diverted, along with flow of the Diguillin River, into a system of large primary irrigation canals. This transbasin diversion project was designed to provide economic uplift to the farmers of the region who had not participated in the near countrywide economic boom of the 199Os. Thus the Chilean Government chose to plan, design, and build the project while still maintaining the principle that the private sector should own, operate, and maintain irrigation projects. Additionally, the Directorate of Irrigation of the Ministry of Public Works was empowered, after some 50 years without designing a major irrigation project, to carry out with government financing the Laja Diguillin Project. The coalescence of factors that the Ministry recognized and made effective accommodations for may be grouped into four categories. They were: 1) advocacy, which was strongly provided by Directorate personnel; 2) social, characterized by the challenge to integrate newly enfranchised irrigators with existing water users and their organizations; 3) government, which as a dynamic emergent democracy with an established bureaucracy of skilled technocrats and economists was flexible and able to adopt new or innovative approaches; and 4) competing interests for water and land, embodied in three groups who actively opposed the project for environmental and commercial reasons

Habitat Influences Arthropod Biodiversity

Biodiversity is an important indicator of environmental health. Insects are very interconnected ecologically, very adaptable, and highly diverse, making them excellent indicators for environmental health. Human interference tends to disrupt ecosystems to make them less diverse (Benton et al. 2003). A greater variety of plants should be expected to support a greater variety of insects, aiding environmental health (e.g., Diniz et al. 2010). We tested the effect of degree of habitat disturbance/plant diversity on insect diversity in 6 habitats over three dates, expecting to see greater insect diversity where there is greater plant diversity. We calculated insect biodiversity using Simpson’s Index of Diversity, and found greater insect abundance and diversity in more diverse habitats. Insect diversity is important for habitat health, so as insect diversity declines, other animals in those ecosystems suffer as well, as the food web is disrupted (Kemp and Ellis 2017)

Upset Simulation and Training Initiatives for U.S. Navy Commercial Derived Aircraft

Militarized versions of commercial platforms are growing in popularity due to many logistical benefits in the form of commercial off-the-shelf (COTS) parts, established production methods, and commonality for different certifications. Commercial data and best practices are often leveraged to reduce procurement and engineering development costs. While the developmental and cost reduction benefits are clear, these militarized aircraft are routinely operated in flight at significantly different conditions and in significantly different manners than for routine commercial flight. Therefore they are at a higher risk of flight envelope exceedance. This risk may lead to departure from controlled flight and/or aircraft loss1. Historically, the risk of departure from controlled flight for military aircraft has been mitigated by piloted simulation training and engineering analysis of typical aircraft response. High-agility military aircraft simulation databases are typically developed to include high angles of attack (AoA) and sideslip due to the dynamic nature of their missions and have been developed for many tactical configurations over the previous decades. These aircraft simulations allow for a more thorough understanding of the vehicle flight dynamics characteristics at high AoA and sideslip. In recent years, government sponsored research on transport airplane aerodynamic characteristics at high angles of attack has produced a growing understanding of stall/post-stall behavior. This research along with recent commercial airline training initiatives has resulted in improved understanding of simulator-based training requirements and simulator model fidelity.2-5 In addition, inflight training research over the past decade has produced a database of pilot performance and recurrency metrics6. Innovative solutions to aerodynamically model large commercial aircraft for upset conditions such as high AoA, high sideslip, and ballistic damage, as well as capability to accurately account for scaling factors, is necessary to develop realistic engineering and training simulations. Such simulations should significantly reduce the risk of departure from controlled flight, loss of aircraft, and ease the airworthiness certification process. The characteristics of commercial derivative aircraft are exemplified by the P-8A Multi-mission Maritime Aircraft (MMA) aircraft, and the largest benefits of initial investigation are likely to be yielded from this platform. The database produced would also be utilized by flight dynamics engineers as a means to further develop and investigate vehicle flight characteristics as mission tactics evolve through the years ahead. This paper will describe ongoing efforts by the U.S. Navy to develop a methodology for simulation and training for large commercial-derived transport aircraft at unusual attitudes, typically experienced during an aircraft upset. This methodology will be applied to a representative Navy aircraft (P-8A) and utilized to develop a robust simulation that should accurately represent aircraft response in these extremes. Simulation capabilities would then extend to flight dynamics analysis and simulation, as well as potential training applications. Recent evaluations of integrated academic, ground-based simulation, and in-flight upset training will be described along with important lessons learned, specific to military requirements

Age-related differences in dual task walking: a cross sectional study

<p>Abstract</p> <p>Background</p> <p>Variability in stride velocity during walking characterizes gait instability and predicts falling in older individuals. Walking while executing a cognitive task is also associated with increased risk of falling, particularly in older adults. Variability in stride velocity, particularly during dual task walking conditions, may differ between younger and older individuals. The purpose of this study was to examine whether gait velocity and variability in stride velocity differ between older community-dwelling women and younger women during dual task walking.</p> <p>Methods</p> <p>Twenty-three older (80 ± 9 years) and 19 younger (23 ± 2 years) women walked under each of two conditions: (1) walking at a self-selected velocity and (2) walking at a self-selected velocity while incrementally counting backwards. Gait velocity and variability in stride velocity were measured with GAITRite^®instrumentation.</p> <p>Results</p> <p>Gait velocity decreased and variability in stride variability increased, in both groups, during dual task walking. The relative reduction in gait velocity and the magnitude of variability in stride velocity were greater in the older subjects than younger subjects.</p> <p>Conclusion</p> <p>The gait changes observed in dual task walking characterize reduced gait stability and indicate that cognitively demanding tasks during walking have a destabilizing effect on gait that may place older persons at greater risk of falls.</p

Energy spectra and photoluminescence of charged magneto-excitons

Charged magneto-excitons X- in a dilute 2D electron gas in narrow and symmetric quantum wells are studied using exact diagonalization techniques. An excited triplet X- state with a binding energy of about 1 meV is found. This state and the singlet are the two optically active states observed in photoluminescence (PL). The interaction of X-'s with electrons is shown to have short range, which effectively isolates bound X- states from a dilute e-h plasma. This results in the insensitivity of PL to the filling factor nu. For the "dark" triplet X- ground state, the oscillator strength decreases exponentially as a function of 1/nu which explains why it is not seen in PL.Comment: 3 pages, 4 figures, submitted to Physica
