MANOVA modelling of a chiropractic longitudinal study using multiple imputation
No full textThe purpose of this report is to present the detailed statistical analysis of a randomised, placebo-controlled trial comparing two different treatment modalities to an intervention of no known benefit for people with acute or subacute thoracic spine pain.
The therapy arms consist of Spinal Manipulative Therapy (SMT) and Graston Technique (GT) and the placebo is a non-functional ultrasound. A placebo group was utilised because at present there are no proven treatments for non-specific thoracic pain. This trial is registered with the Australia and New Zealand Clinical Trials Registry. Ethics approval has been granted by Murdoch University Human Research and Ethics Committee, number 2007/274.
The aim of this three arm trial was to test the efficacy of SMT and GT as independent modalities compared to detuned ultrasound for the outcomes of pain and disability. The latter were measured using the Visual Analogue Scale (VAS) and a modified Oswestry Back Pain Disability Index. The study was conducted at the Murdoch University Chiropractic student clinic in Perth, Australia, and the protocol published in Crothers et al (2008).
In this report, Section 2 provides an initial exploratory analysis of the data, Section 3 outlines the statistical models used in the final analysis, Section 4 defines these models in mathematical terms, Section 5 discusses the management of missing values via multiple imputation and Section 6 presents the results of the statistical modelling and hypothesis tests. The clinical study will be published in full elsewhere
An electrophoretic analysis of glycoproteins in the mid-brain fluid of fetal rats, 1979
No full textAn electrophoretic analysis was carried out on the mid-brain fluid of fetal rats from 13% to 14% days of gestation. This study was conducted to identify and monitor the glycoproteins synthesized during fetalogenesis of the rat brain on days 13% and 14%. In 13% days of gestation the total protein concentration increases from 0.1033 mg/ 100 ml to a mean of 0.1135 mg/100 ml on 14% day of gestation. The densitometric scans of 13% day fetuses mid-brain fluid showed a maximum of 2 bands and 14% day showed a maximum of 3 bands on SDS polyacrylamide gel electrophoresis. Molecular weight determinations of glycoproteins from mid-brain fluid samples of 13% day fetuses yielded readings of 19,600 and 68,000 Daltons and 45,000, 26,000, 35,500 Daltons from those of 14% day fetuses. The finding of this investigation supports the postulation that glycoprotein concentration and variation in types occur during brain morphogenesis. Consequently these compounds may serve as monitors of brain cell differentiation during rat fetalogenesis. It is a pleasure to express an infinite amount of gratitude to Dr. John M,, Browne who has so generously rendered his time and services towards assisting me in the accomplishment of this manuscript. Also I would like to thank my mother, Mrs. Betty S. Theodore, family and friends who has given me an endless amount of moral support throughout the duration of this work
An alternative definition of economic regions in the U.S. based on similarities in state business cycles
No full textSince the 1950s the Bureau of Economic analysis (BEA) has grouped the states into eight regions based primarily on cross-sectional similarities in their socioeconomic characteristics. This is the most frequently used grouping of states in the U.S. for economic analysis. Since several recent studies concentrate on similarities and differences in regional business cycles, this paper groups states into regions based not on a broad set of socioeconomic characteristics but on the similarities in their business cycles. The analysis makes use of a consistent set of coincident indexes estimated from a Stock and Watson-type model. The author applies k-means cluster analysis to the cyclical components of these indexes to group the 48 contiguous states into eight regions with similar cycles. Having grouped the states into regions, the author determines the relative strength of cohesion among the states in the various regions. Finally, the author compares the regions defined in this paper with the BEA regions.Business cycles ; Regional economics
Verified compilation of abstract network policies
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2019Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 67-68).Configuring large networks can be very complex. A network administrator typically has a set of high-level policies in mind when creating a network configuration, but implementing the configuration onto existing hardware often requires specifying many low-level details. As a result, configuring a network is currently a very error-prone process, and misconfigurations resulting in network outages and security vulnerabilities occur frequently in practice. We present a formally verified compiler from high-level network policies to low-level executable routing rules, to simplify the process of correctly conguring networks and enforcing network policies.by Theodore Katz.M.

Sacrifice in the Eucharist in the texts of the fathers from the New Testament to the council of Chalcedon
No full textThis thesis examines the evidence for the notion of Eucharistic Sacrifice which is found in the original texts of all the principal Fathers and ecclesiastical authors of the Early Church. The period covered is from the time of the writing of the New Testament to the Council of Chalcedon in 451 A.D. Each of the principal Fathers is examined in historical order, as far as this is possible, except when there is another link between them such as their city of origin. Apart from a few exceptions, the texts are presented in their Greek or Latin original in the footnotes, but an English translation is supplied for every case in the main text of the thesis. The aim of the thesis is not to provide an exhaustive analysis of the above data, but to present them in an orderly way and to make initial exploratory comments on the texts themselves and of the work of various scholars. The final conclusion resulting from this exercise is that, although there is indisputable evidence that the notion of Eucharistic sacrifice was widely upheld by Patristic authors, its actual content varied from author to author and presents a richness which it is not easy to classify
Family altruism and incentives
No full textThe author builds on the altruistic model of the family, to explore the strategic interaction between altruistic parents, and selfish children, when children's efforts are endogenous. If there is uncertainty about the amount of income the children will realize, and if parents have imperfect information, the children have an incentive to exert little effort, and to rely on their parent's altruistically motivated transfers. Because of this, parents face a tradeoff between the insurance that bequests implicitly provide their children, and the disincentive to work prompted by their altruism. The author shows that if parents can credibly commit to a pattern of transfers, they will choose not to compensate children in bad outcomes, as much as predicted by the standard (no uncertainty, no asymmetric information) dynastic model of the family. Alternatively, parents may choose to forgo any insurance, and offer a fixed level of bequest, to elicit greater effort from their children. The optimal transfers structure that the author derives, reconciles the predictions of the altruistic family model, with much of the existing evidence on inter-generational transfers, which suggests that parents compensate only partially, or not at all, for earnings differentials among their children. Moreover, the author shows that Ricardian equivalence holds in this setup, except when non-negativity constraints are binding.Economic Theory&Research,Environmental Economics&Policies,Health Economics&Finance,Educational Sciences,Safety Nets and Transfers
