    The core of teaching is the relationship of care between the student and the teacher. A community can be created in the classroom that honors and respects the inherent worth of each individual and through such mutual respect students and teachers can experience success. The suffering and the successes that teachers experience are central to the way they care for their students. There is currently a great deal of focus on education and schooling in the United States and generally this focus ignores the necessity and vitality of the relationship of care. Teachers must daily support and care for students who have great struggles and great triumphs. In my dissertation, I will explore the nature of the experience of these teachers as they work with students who experience suffering and success. I will identify the themes of their experience using a hermeneutic phenomenological methodology based on the work of Max Van Manen. This dissertation is essentially a philosophical examination of the nature of teachers’ care for students and how they manifest the experience of suffering and success of those students. Therefore it is a deeply phenomenological work, bound not by the empirical, but by the life- worlds of the participants and of the author.

    Get PDF
    An archaeological survey of the Friedrich Park property, in north Bexar County, Texas, was conducted by the Center for Archaeological Research, University of Texas at San Antonio. These investigations were made at the request of the Parks and Recreation Department of the City of San Antonio. The field work was undertaken by the authors during the months of May and July, 1975. All field activities were carried out under the terms of State Antiquities Permit No. 83. Friedrich Park is located in northern Bexar County, approximately 10 miles north of IH 410 and west of IH 10. The specific area examined encompassed a total of approximately 200 acres. The purpose of the survey was to ascertain the existence of any historic or archaeological resources which should be preserved in the interest of the park. Once resources were found, the task of the survey team was to evaluate the nature and the significance of the sites

    Tidally-Triggered Star Formation in Close Pairs of Galaxies

    We analyze new optical spectra of a sample of 502 galaxies in close pairs and n-tuples, separated by <= 50/h kpc. We extracted the sample objectively from the CfA2 redshift survey, without regard to the surroundings of the tight systems. We probe the relationship between star formation and the dynamics of the systems of galaxies. The equivalent widths of H\alpha (EW(H\alpha) and other emission lines anti-correlate strongly with pair spatial separation (\Delta D) and velocity separation. We use the measured EW(H\alpha) and the starburst models of Leitherer et al. to estimate the time since the most recent burst of star for- mation began for each galaxy. In the absence of a large contribution from an old stellar population to the continuum around H\alpha, the observed \Delta D -- EW(H\alpha) correlation signifies that starbursts with larger separations on the sky are, on average, older. By matching the dynamical timescale to the burst timescale, we show that the data support a simple picture in which a close pass initiates a starburst; EW(H\alpha) decreases with time as the pair separation increases, accounting for the anti-correlation. This picture leads to a method for measuring the duration and the initial mass function of interaction-induced starbursts: our data are compatible with the starburst and orbit models in many respects, as long as the starburst lasts longer than \sim10^8 years and the delay between the close pass and the initiation of the starburst is less than a few \times 10^7 years. If there is no large contribution from an old stellar population to the continuum around H\alpha the Miller-Scalo and cutoff (M <= 30 M_\sun) Salpeter initial mass functions fit the data much better than a standard Salpeter IMF.

    Crew Exploration Vehicle Ascent Abort Overview

    Get PDF
    One of the primary design drivers for NASA's Crew Exploration Vehicle (CEV) is to ensure crew safety. Aborts during the critical ascent flight phase require the design and operation of CEV systems to escape from the Crew Launch Vehicle and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage. These studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the CEV, driving requirements for abort scenarios, and an overview of current ascent abort modes. Example analysis results are then discussed. Finally, future areas for abort analysis are addressed

    Best management practices in counting urban black bears

    DNA-based capture-mark-recapture (CMR) techniques are commonly used to obtain population parameters of black bears (Ursus americanus) in rural and wildland landscapes; however, these techniques have not been implemented in urban clusters (i.e., 2,500 to 50,000 residents). Black bears can readily habituate to urban clusters, and wildlife managers need to monitor and manage these urban bear populations. We modified DNAbased CMR for black bear using hair-snares to take into account the small home ranges of urban bears, urban bear behavior, and human safety within Mammoth Lakes, California, USA. We conducted this study for 3 fi eld seasons in 2010, 2011, and 2012 from June to July. Each fi eld season, we implemented a CMR with 6 encounter occasions, each 7 days in length. We used the traditional corral hair-snare design modified for human safety and chose multiple non-consumable and minimally consumable lure types to prevent food conditioning and a trap-happy response. In 2012, we also tested 3 additional hair-snare designs more appropriate for urban areas: natural rub, haphazard-wire snare, and tennis ball snare. In 2010, we collected an insufficient number of hair samples for CMR by putting hair-snares in the periphery of the urban cluster, which we call the urban–wildland interface. However, in 2011 and 2012, when we put hair-snares in the city center as well as the surrounding urban–wildlife interface and increased hair-snare density, we obtained a sufficient number of hair samples to estimate population density using closed capture CMR models. These adjustments to hairsnaring study design in urban areas helped increase capture and recapture rates to be similar to our wildland area. To achieve high capture rates using hair-snares in the urban area, we put out hair-snares at a density approximately 4 times greater than in our wildland study area and distributed them throughout the entire urban area, and not just on the urban–wildlife interface. In addition, setting hair-snares near anthropogenic features used by bears in urban areas (e.g., culverts, utility poles, dumpsters) and adding spent cooking oil to lures also increased our capture rate. Finally, the corral hair-snare had the highest capture rates of our 4 hair-snare designs. After adapting a study design for hair-snaring wildland bears, our methods were efficient for urban areas, having high capture and recapture rates (\u3e0.30) and good precision for abundance estimates (coefficient of variatio

    Complexity and Inapproximability Results for Parallel Task Scheduling and Strip Packing

    Full text link
    We study the Parallel Task Scheduling problem PmsizejCmaxPm|size_j|C_{\max} with a constant number of machines. This problem is known to be strongly NP-complete for each m5m \geq 5, while it is solvable in pseudo-polynomial time for each m3m \leq 3. We give a positive answer to the long-standing open question whether this problem is strongly NPNP-complete for m=4m=4. As a second result, we improve the lower bound of 1211\frac{12}{11} for approximating pseudo-polynomial Strip Packing to 54\frac{5}{4}. Since the best known approximation algorithm for this problem has a ratio of 43+ε\frac{4}{3} + \varepsilon, this result narrows the gap between approximation ratio and inapproximability result by a significant step. Both results are proven by a reduction from the strongly NPNP-complete problem 3-Partition

    Comparing urban and wildland bear densities with a DNA-based capture-mark-recapture approach

    California’s black bear (Ursus americanus) population has tripled over the last 3 decades, causing an increased incidence of human–bear conflicts, many of which now occur in urban areas. Consequently, it is imperative that bear managers have the ability to monitor population parameters in both wildland and urban environments to help manage bears. Capture-mark-recapture (CMR) methods using uniquely typed genetic samples (DNA) collected via hair-snares have been widely used to monitor bears in wildland areas. However, we are unaware of researchers applying this technique to bears occupying urban areas. We implemented a multi-year DNA-based CMR study to compare bear densities between an urban area and a nearby wildland area. We deployed hair-snares for 6 weekly capture occasions during June and July, 2011 and 2012. We uniquely typed DNA from snared hair follicles using 14 microsatellite loci and 2 sexing loci. We coupled unique identification with robust-design closed-capture models and model averaging in Program MARK to estimate abundance. We identified 41 and 62 individual bears on the urban and wildland study areas, with average densities of 3.8 and 1.8 bears/10 km2,respectively. Our data support the hypothesis that bears can occur at greater densities in urban areas. Based on these results, we recommend using DNA-based CMR methods to monitor populations of bears in urban areas, but we suggest increasing the density of sampling locations to account for greater bear densities. Furthermore, we contend that DNA-based CMR can also estimate survival, recruitment, rate of population change (λ), and identify movement patterns by incorporating additional survey years
