Support for the use of progress monitoring results for high-stakes decisions is emerging in the literature, but few studies support the reliability of the measures for this level of decision-making. What little research exists is limited to oral reading fluency measures, and their reliability for progress monitoring (PM) is not supported. This dissertation explored methods rarely applied in the literature for summarizing and analyzing progress monitoring results for medium- to high-stakes decisions. The study was conducted using extant data from 92 "low performing" third graders who were progress monitored using mathematics concept and application measures. The results for the participants in this study identified 1) the number of weeks needed to reliably assess growth on the measure; 2) if slopes differed when results were analyzed with parametric or nonparametric analyses; 3) the reliability of growth; and 4) the extent to which the group did or did not meet parametric assumptions inherent in the ordinary least square regression model. The results indicate reliable growth from static scores can be obtained in as few as 10 weeks of progress monitoring. It was also found that within this dataset, growth through parametric and nonparametric analyses was similar. These findings are limited to the dataset analyzed in this study but provide promising methods not widely known among practitioners and rarely applied in the PM literature.

This report consider a system describing three competing species with populations x, y and z. Sufficient conditions for every positive equilibrium to be asymptotically stable have been found. First it is shown that conditions on the pairwise competitive interaction between the populations are needed. Actually, these conditions are equivalent to asymptotic stability for any two-dimensional competing system of the three species. It is also shown that these alone are not enough, and that a condition on the competitive interaction between all three populations is also needed. If all conditions are fulfilled, each population will survive on a long-term basis and there will be a stable coexistence.

This thesis is written with the purpose to analyze immigrants’ effect on new firm formation. Immigrants can ease future sustenance problems of decreasing population growth and growing life expectancy. Immigrants start new firms to a higher extent than ethnic Swedes. Two reasons to that immigrants start new firms is to get out of unemployment and to satisfy a demand of products preferred by certain groups. This thesis point out cultural and structural factors that contribute to higher immigrant new firm formation rates and what in general diverges from ethnic Swedes’ new firm formation. Also, push and pull effects are discussed. The ordinary and the advanced service sector in Sweden, where 76 % of all new firms were started in 2005, are studied. The result that emerged shows that immigrants from non-Nordic countries have a positive effect on new firm formation. However, people from FIND-countries (Finland, Iceland, Norway and Denmark) did not have a positive effect on new firm formation.

Why do ordinary individuals participate in mass violence perpetrated against civilians? That is the question I will attempt to answer in the following paper. I consider these men ordinary to the extent that the majority was not socially deviant. Looking at the case of Nazi Germany, two groups stand out as good case studies: the SS Einsatzgruppen and the SS cadres in the Death camps. The following analysis will focus on the motivations of these men to commit mass murder. I argue for a causal sequence of action, beginning with the onset of Nazi ideology, further followed by the dehumanization of the victim and the brutalization of the perpetrator. I will demonstrate how the ideology present during German interwar society influenced these men into participation. Dehumanization and brutalization are complimentary factors that push these men into action.

In this study we seek to understand how ordinary Chinese people perceive Westerners as the Other through examining their intercultural experiences. In contrast to the numerous studies of social elites’ Occidentalism, this study shifts the attention to ordinary people’s perceptions in a fast changing Chinese society. From an interpretive perspective, we conducted semi-structured interviews with 16 participants living in a coastal city in Mainland China. The key findings suggest that the Chinese public has its own way of perceiving and presenting the Western Other. Also, this Other, being defined in an on-going process of intercultural interaction, connotes a wider meaning – a unity of opposition and complementarity, exclusion and inclusion. Thus this study has deepened our understanding of the Chinese construction of the Western Other. The findings can be used in developing intercultural communication training programs to facilitate deeper contact and better dialogue between the Chinese and Westerners.

The 87Rb-86Sr system is a widely used long-lived isotope geochronometer. 87Rb, the naturally occurring radioactive isotope of Rb, undergoes beta-decay to stable 87Sr with a half-life of approximately 50 Ga. Decay of 87Rb to 87Sr results in variable 87Sr/86Sr in minerals with different Rb/Sr, and measurement of 87Rb/86Sr and 87Sr/86Sr allows for the determination of the age of the rock. Accurate ages depend both on the quality of the isotopic analysis and on the accuracy of the 87Rb decay constant, lambda87. Although the currently accepted value for lambda87 of 1.42 × 10-11a-1 has been in use for over 30 years, there is growing evidence that it is not accurate. Recent attempts to refine lambda87 and its precision have not reached a consensus. This thesis describes a new experiment to measure lambda87 by 87Sr accumulation over a period of about 30 years, and the preparation of a 84-86Sr double-spike in conjunction with that experiment. Radiogenic 87Sr produced in aliquots of a RbClO4 salt was measured by isotope dilution thermal ionization mass spectrometry. An average of 31 measurements yields a value of 1.398 ± 0.003 × 10-11a-1 . This requires a substantial revision from the previously accepted decay constant and makes Rb-Sr ages calculated with it 1.5% older. A Rb-Sr and U-Pb isotopic chronometry study was carried out on thirteen ordinary chondrites – the most common type of meteorite, the origin and history of which are still unclear. Some meteorites appear disturbed, possibly by recent shock during breakup of the parent body, whereas others yielded accurate and precise U-Pb and Pb-Pb ages. For example, L5 Elenovka yielded distinct ages for silicates (4555 Ma) and phosphates (4535 Ma), allowing the cooling rate of this meteorite from approximately 1055 K to 759 K to be constrained to 15 ± 3 K/Ma. Rb-Sr yielded less precise ages than U-Pb, but using the new decay constant allows accurate comparison between the two methods. This study creates a firm foundation for future studies in thermal history of chondrites and terrestrial metamorphic complexes using Rb-Sr together with other isotopic chronometers.

Boundary value problems (BVPs) are systems of ordinary differential equations (ODEs) with boundary conditions imposed at two or more distinct points. Such problems arise within mathematical models in a wide variety of applications. Numerically solving BVPs for ODEs generally requires the use of a series of complex numerical algorithms. Fortunately, when users are required to solve a BVP, they have a variety of BVP software packages from which to choose. However, all BVP software packages currently available implement a specific set of numerical algorithms and therefore function quite differently from each other. Users must often try multiple software packages on a BVP to find the one that solves their problem most effectively. This creates two problems for users. First, they must learn how to specify the BVP for each software package. Second, because each package solves a BVP with specific numerical algorithms, it becomes difficult to determine why one BVP package outperforms another. With that in mind, this thesis offers two contributions. <p> First, this thesis describes the development of the BVP component to the fully featured problem-solving environment (PSE) for the numerical solution of ODEs called pythODE. This software allows users to select between multiple numerical algorithms to solve BVPs. As a consequence, they are able to determine the numerical algorithms that are effective at each step of the solution process. Users are also able to easily add new numerical algorithms to the PSE. The effect of adding a new algorithm can be measured by making use of an automated test suite. <p> Second, the BVP component of pythODE is used to perform two research studies. In the first study, four known global-error estimation algorithms are compared in pythODE. These algorithms are based on the use of Richardson extrapolation, higher-order formulas, deferred corrections, and a conditioning constant. Through numerical experimentation, the algorithms based on higher-order formulas and deferred corrections are shown to be computationally faster than Richardson extrapolation while having similar accuracy. In the second study, pythODE is used to solve a newly developed one-dimensional model of the agglomerate in the catalyst layer of a proton exchange membrane fuel cell.

Based on a year of ethnographic fieldwork, this dissertation explores the inextricable relationship of the ordinary and extraordinary which characterizes the lives of U.S. soldiers severely injured in Iraq and Afghanistan and rehabilitating at Walter Reed Army Medical Center in Washington D.C. in 2007-2008. Living among their fellows and families at Walter Reed, the precariousness which marks injured soldiers’ bodies and lives takes on a feeling of ordinariness. And though these injured soldiers and their families do not quite coalesce into a community, their shared experience of being in common with each other—of sharing Walter Reed’s particular and precarious ordinary—helps make life there bearable. Through a poetics of the extra/ordinary I explore how injured soldiers’ ordinariness bristles against inescapable invocations of patriotic sacrifice; the ways soldiers’ everyday movements are marked by being post-traumatic; and the reconfigurations of intimate social relations and masculinity such experiences occasion and out of which the possibilities and limits of a future life emerge. I show that in this moment of life—one which unfolds in a space saturated with narratives of heroic patriotic sacrifice and histories of war and the remaking of men—ordinariness becomes central to injured soldiers’ current experiences and also to the future selves and social configurations they are oriented towards. I demonstrate how injured soldiers’ lives are also always attached to something that exceeds the ordinary; that they are extra/ordinary. But I argue that such extra/ordinariness is an amplification of life’s less notable uncertainties; that all lives are extra/ordinary. Against the over-determining frames of heroism and trauma within which U.S. soldiers are figured, especially in post-9/11 America, I argue that injured U.S. soldiers’ experiences are neither simply knowable, nor unimaginable but recognizable as specifically tethered to, commensurable with, and distinguished from, more ‘ordinary’ others.
