Surgery on links of linking number zero and the Heegaard Floer dd-invariant

We study Heegaard Floer homology and various related invariants (such as the $h$-function) for two-component L-space links with linking number zero. For such links, we explicitly describe the relationship between the $h$-function, the Sato-Levine invariant and the Casson invariant. We give a formula for the Heegaard Floer $d$-invariants of integral surgeries on two-component L-space links of linking number zero in terms of the $h$-function, generalizing a formula of Ni and Wu. As a consequence, for such links with unknotted components, we characterize L-space surgery slopes in terms of the $\nu^{+}$-invariants of the knots obtained from blowing down the components. We give a proof of a skein inequality for the $d$-invariants of $+1$ surgeries along linking number zero links that differ by a crossing change. We also describe bounds on the smooth four-genus of links in terms of the $h$-function, expanding on previous work of the second author, and use these bounds to calculate the four-genus in several examples of links.Comment: This version accepted for publication in Quantum Topolog

Juvenile Justice: The Nathaniel Abraham Murder Case

Once in a while, a case will come along that has such an enormous impact on the law that it is certain to draw attention. One such case was the Nathaniel Abraham murder case----a case involving the sentencing of a young eleven-year-old child in a system designed for older juvenile offenders, which demonstrated some of the novel and important issues facing the juvenile courts today. With the onset of such issues, the Juvenile Justice System has developed into a complex field of vital importance. Investing in the Juvenile Justice System allows us to invest in our future. Although frequently viewed as a social issue, rehabilitation of youthful offenders should become a goal for the legal profession as well as for members of the public. With proper education, training, and commitment to the field of juvenile justice, we can begin to preserve, protect, and improve our most precious assets-our youth

A Study of SATP Scores and Principals’ Perceptions for Traditional and Alternate Routes to Teacher Certification

This study explores the differences between traditional and alternate route certification by focusing on the achievement of students who have been instructed by teachers from each program. In addition, this study identifies the strengths and weaknesses of teachers from each certification route through surveys and interviews with principals in the sample. Previous studies on this subject have focused on elementary or middle schools, which limits the information available for the high school level. This study was directed toward high school teachers in core subject areas tested in Mississippi’s accountability model. The purpose of this study was to connect student test scores to the teachers’ certification routes and to identify strengths and weaknesses of each route through feedback from principals. The Mississippi Subject Area Test (MSAT) scores in Algebra I, Biology I, English II, and U. S. History were analyzed. The test results revealed no significant advantages or difference for either teacher certification route; however, the data collected from principals indicated a perceived advantage for traditional route teachers. This study distinguishes the differences between accumulated student test results and perceptions by principals. The results provide high school administrators with a resource to compare high school test scores of students instructed by traditional or alternate route teachers

Initial surface reactions and nucleation kinetics of boron on atomically clean molybdenum substrates

A study of the chemical vapor deposition (CVD) of boron from boron triiodide (BI3) on molybdenum has been done with field emission microscopy (FEM) and low energy electron diffraction (LEED). A correlation of the efficiency by which BI3 is effectively dissociated to form adsorbed boron, and the temperature of the substrate has been shown through work function measurements on the boron covered molybdenum field emitter surfaces. The boron-induced work function change of molybdenum has been shown to be in agreement with a theoretical model which predicts positive, as well as negative work functions for adsorbate-substrate systems. It has previously been found that the theoretical model can be used to accurately determine the occurence of the adsorbate monolayer. By comparison of the experimental work function data with the theoretical model inferrence of the thermal accommodation coefficient, of the adsorbate source species (BI3), on the substrate is made. The free energy of desorption of boron from molybdenum field emitter surfaces has been measured by isothermal desorption experiments and been found to be 46.9 kcal/mole at boron coverages of about 0.4 monolayer. The time-dependent adsorption, leading to nucleation of boron on molybdenum field emitter surfaces has been observed to occur at about 0.5 monolayer coverages of boron. LEED studies of a Mo(100) single crystal at substrate temperatures of 700°C to 900°C in BI3 partial pressures of 3 x 10-8 torr result in no structure change relative to the clean surface, even at prolonged exposures to BI3. However, under the same experimental conditions, the Mo(110) surface exhibits the formation of one-dimensional disordered structures with the original ordering maintained in an orthogonal direction to the disorder --Abstract, pages ii-iii

Residual negative symptoms differentiate cognitive performance in clinically stable patients with schizophrenia and bipolar disorder

Cognitive deficits in various domains have been shown in patients with bipolar disorder and schizophrenia. The purpose of the present study was to examine if residual psychopathology explained the difference in cognitive function between clinically stable patients with schizophrenia and bipolar disorder. We compared the performance on tests of attention, visual and verbal memory and executive function of 25 patients with schizophrenia in remission and 25 euthymic bipolar disorder patients with that of 25 healthy controls. Mediation analysis was used to see if residual psychopathology could explain the difference in cognitive function between the patient groups. Both patient groups performed significantly worse than healthy controls on most cognitive tests. Patients with bipolar disorder displayed cognitive deficits that were milder but qualitatively similar to those of patients with schizophrenia. Residual negative symptoms mediated the difference in performance on cognitive tests between the two groups. Neither residual general psychotic symptoms nor greater antipsychotic doses explained this relationship. The shared variance explained by the residual negative and cognitive deficits that the difference between patient groups may be explained by greater frontal cortical neurophysiological deficits in patients with schizophrenia, compared to bipolar disorder. Further longitudinal work may provide insight into pathophysiological mechanisms that underlie these deficits

Principles and techniques of personnel organization and classification applicable to the United States Navy.

This thesis document was issued under the authority of another institution, not NPS. At the time it was written, a copy was added to the NPS Library collection for reasons not now known.  It has been included in the digital archive for its historical value to NPS.  Not believed to be a CIVINS (Civilian Institutions) title.There Is no subject of more vital Importance to the U.S. Navy today than Personnel Administration In all of Its any phases. Experience In world today demonstrated that In a time of national emergency the manpower resources of the nation are not inexhaustible. The Individual capabilities of every person must be used to the maximum If the nation Is to achieve Its maximum efficiency In a time of crisis. This Is true In every field of endeavor— in Industry, In public service, In the armed forces, In education and training, when technical knowledge and methods of production are at nearly equal as they are In the world today, the margin of superiority In event of an armed conflict will rest with the nation which makes the best utilization of Its human resources. The armed forces must be so organized and administered that they make their full contribution to the conservation of human resources.http://www.archive.org/details/principlestechni00moorU.S. Navy (U.S.N.) author

The Production of High-Quality Video for E-Learning

As video capture, editing and transmission capabilities become more accessible, video is increasingly being considered when developing e-learning content. However, the skills required for video production are not commonly part of many e-learning developers backgrounds. This paper presents the experiences of academics from the spatial information sciences when developing high quality video content for an on-line e-learning module in Global Navigation Satellite Systems (GNSS). Video comprises one element of the module and is designed to, as far as possible, address the lack of ‘hands-on’ experience of GNSS equipment and observing procedures. The video element of the module was used by a cohort of post-graduate students at the Technological University of Dublin and the feedback was favourable. While acknowledging its advantages, the authors conclude that the cost, time and complexity of producing high-quality video should not be underestimated. Also, they note that keeping multimedia-rich courses current, particularly in an area of rapid technological change, is a challenge. E-learning course developers considering using video should carry-out both a pedagogical- and a cost-benefit analysis to establish if the inclusion of video is worthwhile. The most important component in producing an active learning experience continues to be the quality of the instructional design and content, not the media itself
