    Problem children present a major concern in the field of education. Because they are not adjusting to the socially-acceptable behavior norms of their environment, they disrupt their own progress and the learning efforts of their classmates. PURPOSE: The purpose of this study was to determine the effectiveness of school counselors involving problem children in a middle school with their teacher and parent(s) in a contractual agreement. This contractual agreement was based upon Glasser\u27s Reality Therapy and tailored to the individual problem child\u27s own needs, in order to help him to improve his behavior and achievement. PROCEDURE: The treatment group was composed of middle school problem children, so designated and rated by the classroom teacher on the Devereux Elementary School Behavior Rating Scale. The non-treatment group consisted of three intact homerooms, one at each grade level, most closely approximating that mean grade level in terms of Stanford Achievement Test scores. The pretest for both groups in the Paragraph Meaning and Arithmetic Computation subtests of the Stanford Achievement Test was a part of the school testing program. As soon as the problem child was designated, he was involved in a contractual agreement with his counselor, teacher, and parent(s). At the end of the school year, posttesting in the two subtests was administered to the treatment and to the non-treatment groups. The treatment group was again rated by the classroom teacher on the behavior rating scale. Five dependent variables were investigated for the treatment group: gradepoint average, paragraph meaning, arithmetic computation, grade in the subject of the designating teacher, and behavior. Three dependent variables were investigated for the non-treatment group: grade-point average, paragraph meaning, and arithmetic computation. FINDINGS: The data for the experimental group was analyzed by employing the Student t-test for correlated samples to test for a significant mean gain for the dependent variables of this group. The non-experimental group was used as a secondary comparison. The .05 level of statistical significance was used for testing the null hypotheses. Problem children, as well as non-problem children, made significant gains in grade-point average, paragraph meaning, and arithmetic computation. The gain of the Problem children was not significantly higher than that of the non-problem children. The problem children received significantly fewer deviations from the mean on the behavior rating scale at the end of the year, but did not make a significant gain in the subject of the designating teacher. CONCLUSION: From the significant gains of the treatment group and from subjective impressions, the researcher concluded that the contractual agreement and Reality Therapy may well be utilized for helping the problem child in the middle school improve his behavioral and achievement

    Swelling of compacted bentonite in organic solvents: Correlation of rate and extent of swelling with solvent properties

    The swelling of clay minerals within shale formations during oil and gas exploration, and within compacted bentonite barriers for radioactive waste containment, presents a number of challenges to operators. Whilst much work has been devoted to understanding the interlayer swelling properties of clay mineral crystals, significantly less has been devoted to understanding coupled pore and interlayer swelling in reactive shale/compacted clay minerals. Here we study the swelling of compacted clay mineral tablets on exposure to a range of organic solvents, selected so that the effect of key solvent properties such as dielectric constant, density, octanol-water partition coefficient, viscosity and surface tension can be correlated with the swelling observed. We use a novel non-contact swelling meter to carry out the swelling tests, allowing us to access information on rate of swelling. Short-term swelling rate showed the strongest correlation to the solvent octanol-water partition coefficient. In long term swelling, good correlation was found between total linear swelling and viscosity, and the octanol-water partition coefficient

    Microrollers Flow Uphill as Granular Media

    Pour sand into a container and only the grains near the top surface move. The collective motion associated with the translational and rotational energy of the grains in a thin flowing layer is quickly dissipated as friction through multibody interactions. Alternatively, consider what will happen to a bed of particles if one applies a torque to each individual particle. In this paper, we demonstrate an experimental system where torque is applied at the constituent level through a rotating magnetic field in a dense bed of microrollers. The net result is the grains roll uphill, forming a heap with a negative angle of repose. Two different regimes have been identified related to the degree of mobility or fluidization of the particles in the bulk. Velocimetry of the near surface flowing layer reveals the collective motion of these responsive particles scales in a similar way to flowing bulk granular flows. A simple granular model that includes cohesion accurately predicts the apparent negative coefficient of friction. In contrast to the response of active or responsive particles that mimic thermodynamic principles, this system results in macroscopic collective behavior that has the kinematics of a purely dissipative granular system

    Abundance Ratios in the Galactic Bulge and Super Metal-Rich Type II Nucle osynthesis

    We present abundance results from our Keck/HIRES observations of giants in the Galactic Bulge. We confirm that the metallicity distribution of giants in the low-reddening bulge field Baade's Window can be well-fit by a closed-box enrichment model. We also confirm previous observations that find enhanced [Mg/Fe], [Si/Fe] and [Ca/Fe] for all bulge giants, including those at super-solar metallicities. However, we find that the [O/Fe] ratios of metal-rich bulge dwarfs decrease with increasing metallicity, contrary to what is expected if the enhancements of the other α\alpha-elements is due to Type II supernovae enrichment. We suggest that the decrease in oxygen production may be due to mass loss in the pre-supernova evolution of metal-rich progenitors.Comment: Conference proceeding to Nuclei in the Cosmos VIII, Vancouver, BC, July, 2004.

    Structure and play: rethinking regulation in the higher education sector

    Get PDF
    This paper explores possible tactics for academics working within a context of increasing regulation and constraint. One suggested tactic is to move outside of a creativity-conformity binary. Rather than understanding creativity and conformity as separable, where one is seen as excluding the other, the authors consider the potential of examining the relationships between them. The theme of 'structure and play' illustrates the argument. In the first part of the paper, using various examples from art and design - fields generally associated with creativity - the authors explore the interrelatedness of creativity and conformity. For example, how might design styles, which are generally understood as creative outcomes, constrain creativity and lead to conformity within the design field? Is fashion producing creativity or conformity? Conversely, the ways in which conformity provides the conditions for creativity are also examined. For example, the conformity imposed by the state on artists in the former communist bloc contributed to a thriving underground arts movement which challenged conformity and state regulation. Continuing the theme of 'structure and play', the authors recount a story from an Australian university which foregrounds the ongoing renegotiation of power relations in the academy. This account illustrates how programmatic government in a university, with its aim of regulating conduct, can contribute to unanticipated outcomes. The authors propose that a Foucauldian view of distributed power is useful for academics operating in a context of increasing regulation, as it brings into view sites where power might begin to be renegotiated

    Road exposure and the detectability of birds in field surveys

    Road ecology, the study of the impacts of roads and their traffic on wildlife, including birds, is a rapidly growing field, with research showing effects on local avian population densities up to several kilometres from a road. However, in most studies, the effects of roads on the detectability of birds by surveyors are not accounted for. This could be a significant source of error in estimates of the impacts of roads on birds and could also affect other studies of bird populations. Using road density, traffic volume and bird count data from across Great Britain, we assess the relationships between roads and detectability of a range of bird species. Of 51 species analysed, the detectability of 36 was significantly associated with road exposure, in most cases inversely. Across the range of road exposure recorded for each species, the mean positive change in detectability was 52% and the mean negative change was 36%, with the strongest negative associations found in smaller-bodied species and those for which aural cues are more important in detection. These associations between road exposure and detectability could be caused by a reduction in surveyors’ abilities to hear birds or by changes in birds’ behaviour, making them harder or easier to detect. We suggest that future studies of the impacts of roads on populations of birds or other taxa, and other studies using survey data from road-exposed areas, should account for the potential impacts of roads on detectability.The BBS is jointly funded by the BTO, JNCC and RSPB.
