Productivity in Higher Education/ Kevin Stange, Kevin Strange, Caroline M. Hoxby.
No full textIn English.How do the benefits of higher education compare with its costs, and how does this comparison vary across individuals and institutions? These questions are fundamental to quantifying the productivity of the education sector. The studies in Productivity in Higher Education use rich and novel administrative data, modern econometric methods, and careful institutional analysis to explore productivity issues. The authors examine the returns to undergraduate education, differences in costs by major, the productivity of for-profit schools, the productivity of various types of faculty and of outcomes, the effects of online education on the higher education market, and the ways in which the productivity of different institutions responds to market forces. The analyses recognize five key challenges to assessing productivity in higher education: the potential for multiple student outcomes in terms of skills, earnings, invention, and employment; the fact that colleges and universities are "multiproduct" firms that conduct varied activities across many domains; the fact that students select which school to attend based in part on their aptitude; the difficulty of attributing outcomes to individual institutions when students attend more than one; and the possibility that some of the benefits of higher education may arise from the system as a whole rather than from a single institution. The findings and the approaches illustrated can facilitate decision-making processes in higher education.Hoxby, Caroline M. / Stange, Kevin -- Staiger, Douglas -- Hoxby, Caroline M. -- Minaya, Veronica / Scott-Clayton, Judith -- Riehl, Evan / Saavedra, Juan E. / Urquiola, Miguel -- Altonji, Joseph G. / Zimmerman, Seth D. -- Courant, Paul N. / Turner, Sarah -- Vlieger, Pieter De / Jacob, Brian / Stange, Kevin -- Deming, David J. / Lovenheim, Michael / Patterson, Richard -- Carrell, Scott E. / Kurlaender, Michal -- Frontmatter -- Contents -- Acknowledgments -- Introduction / 1.

Space, time, and bodies: the dimensions of difference in women's cinema and continental philosophy
No full textThis dissertation examines the question of difference, and especially of sexual difference, in women’s cinema and continental philosophy. I analyze four movies by three of today’s most influential women filmmakers: Jane Campion (The Piano, New Zealand), Claire Denis (Beau Travail and Trouble Every Day, France), and Lucrecia Martel (La niña santa/The Holy Girl, Argentina), as well as philosophical texts by Luce Irigaray, Henri Bergson, Gilles Deleuze, and Friedrich Nietzsche. I argue that these films represent difference not only through characterization, but more essentially by emphasizing one of cinema’s core devices: space (e.g. camerawork), time (narration and editing), and bodies. Through these, the films articulate relations that go beyond hierarchies of power to portray and enact movements toward others who are acknowledged in their singularity. Each chapter is devoted to a film, and opens with a close reading of its aesthetics with a focus on space, time, or bodies. My study of the filmic elements is set in a dialogue with analyses of the corresponding concepts in the philosophical texts. In particular, I explore the relevance for cinema studies of the concept of the interval, which is a central, yet until recently often-overlooked notion in Irigaray’s work. The interval can be defined as the force of difference as it constitutes two subjects (as opposed to a subject and an object) through the distance that both separates and brings them together. It lends itself well to cinematic analysis for it concerns bodies, and it is at once spatial and temporal. The interval itself is brought to bear on other concepts: Bergson’s duration and intuition, Deleuze’s interstice, and Nietzsche’s theory of violence. Through these theoretical and filmic networks, this dissertation sketches out new perspectives for feminist film criticism.A revision of this work was published by Rowman and Littlefield and is available from http://www.rowmaninternational.com/books/the-dimensions-of-difference.Ph.D.Includes bibliographical referencesby Caroline M.

The theory of eucharistic presence in the early Caroline divines, examined in its European theological setting
No full textThe question of Christ's presence in the eucharist was an issue
which caused great controversy in the Reformation period, and which
continued to evoke dispute during the seventeenth century. Various
interpretations of the Caroline divines' teaching on the eucharistic
presence have been offered, but often they seem either to indicate the
theological position of the writer rather than that of the theologians
considered, or to ignore the broader context of eucharistic doctrine.
The purpose of this study, therefore, was 1. to investigate the
theology of eucharistic presence in the thinking of several seventeenth-century
Anglican divines, and 2. to examine their teaching in relation
to the sixteenth-century Anglican heritage and the various continental
sacramental doctrines, Reformed, Lutheran, Roman Catholic and Eastern
Orthodox.
To accomplish this goal, eight theologians were chosen for examination:
Adrianus Saravia, Lancelot Andrewes, John Cosin, Richard
Montague, William Forbes, William Laud, Jeremy Taylor and Herbert
Thorndike. When available, nineteenth-century editions of their works
were used; otherwise, seventeenth-century texts were employed.
Similarly, modern editions of Roman, Orthodox, Lutheran and Reformed
writings were utilized when possible. Thy examination of eucharistic
teaching included seven major points: 1. the sacrament as mystery,
2. eucharistic change, 3. the relationship between Christ's body and
the bread, 4. eucharistic communion, 5. the nature of Christ's body in
the sacrament, 6. consecration, and 7. adoration in the eucharist.
This study has shown that there was great diversity in the
thinking of the Caroline divines (although they did not treat the
subject of eucharistic presence with equal detail or depth); no
unified understanding of sacramental presence was expressed. Reformed
ideas inherited from the previous century remained strong, but new
tendencies toward other understandings of the eucharist can be
discerned. The period, therefore, can be seen to represent a new
stage in the history of Anglican eucharistic doctrine
Olfactory information use for foraging in "Microplitis mediator", a parasitoid of the cabbage moth "Mamestra brassicae"
Get PDFMy PhD project was at the interface between behavioural ecology and biological control, two disciplines that do not easily intertwine because of their divergent aims. On one hand, behavioural ecology is a fundamental science that seeks to understand animal behaviour from an evolutionary perspective and generally works from the point of view of the individual. On the other hand, as an applied science, biological control seeks to elaborate concrete strategies to improve pest control and works from population and community perspectives. However, the success of biological control methods depends on the behaviour of biological control agents, i.e. natural enemies of target pests, which creates a perfect opportunity for behavioural ecology and biological control to work hand in hand. In this work, I studied the foraging behaviour of the larval parasitoid Microplitis mediator (Haliday) (Hymenoptera: Braconidae) with the idea that my findings could contribute to the improvement of the control of its host the cabbage moth Mamestra brassicae (Linnaeus) (Lepidoptera: Noctuidae), which is an important cabbage pest distributed throughout Europe and Asia. Information about the biology, the life cycle and the rearing method of M. mediator and M. brassicae is reviewed in chapter 1.
In a first study (chapter 2), I tested the olfactory attractiveness of flowers/inflorescences of five wildflowers species (bishop’s weed, cornflower, buckwheat, candytuft, and oregano) to naive female M. mediator. I conducted choice tests in a Y-tube olfactometer to test the olfactory attractiveness of flowers/inflorescences against air and the relative attractiveness of the flower species offered in paired choice. I showed that all the flower species were highly attractive to female M. mediator when tested against air, but that in paired choice tests cornflower and candytuft were as attractive as each other and both more attractive than buckwheat. This indicates that M. mediator is able to use olfactory cues to identify potential food sources and has evolved preferences that could be exploited in biological control. In particular, this study has shown that cornflower is a very promising floral subsidy.
However, in a patchy and unpredictable environment, not all food sources are equally abundant and/or near, and parasitoids are expected to have evolved capacities to detect the most promising food sources in terms of proximity and/or abundance. In a second study (chapter 3), I tested whether female Microplitis mediator foraging for food sources, i.e. flowers of cornflower and inflorescences of buckwheat, were able to use quantitative olfactory information to orient themselves towards the most promising (i.e. most abundant and/or closest) food sources. I conducted behavioural assays in a 6-arm olfactometer where groups of six wasps were released and faced with a gradient of volatile concentration created by using different numbers of flowers/inflorescences as odour sources. I also collected and analyzed the volatiles emitted by different numbers of flowers/inflorescences of the two flower species. The results showed that female M. mediator were able to use quantitative olfactory information. In general, they were most attracted to the highest numbers of flowers/inflorescences, which also emitted the highest volatile quantities. However, the response of the wasps towards the two flower species differed. The contrast between the different numbers of flowers/inflorescences was important for the wasps to be able to discriminate and had to be higher with cornflower than with buckwheat. With cornflower, the flower species emitting both substantially higher absolute volatile quantities and more potentially attractive types of volatile compounds (e.g. benzenoïds), the response of the wasps to single flowers was very strong already and showed saturation with increasing numbers of flowers. Conversely, with buckwheat, the flower species emitting low volatile quantities, the response of the wasps to few inflorescences was weak but accelerated with increasing numbers of inflorescences. This would suggest that a higher sensitivity at low volatile quantities than at high volatile quantities could have been selected in M. mediator, which would be adaptive. These results highlight the importance of taking flower density into account to optimize the use of floral subsidies for biological control purposes. In particular, these results suggest that cornflower should be attractive at low densities whereas higher densities of buckwheat could be needed to attract M. mediator in the field.
To conclude, my work has shown that M. mediator is well adapted for food foraging, because it can detect both the quality and the quantity of olfactory information to localize potentially rewarding food sources. I also demonstrated that studying the foraging behaviour of a parasitoid provides relevant information that can be exploited to improve its use for biological control
Imitative ability in preschool age children with autism in the presence of odor
No full textIndividuals with Autism Spectrum Disorder (ASD) are generally thought to be impaired in the ability to imitate, but the causal processes responsible for this deficit are not well understood. Different theoretical perspectives offer different insights as to which behaviors are most difficult for individuals with ASD to imitate and why. This study investigated the imitative ability of five 3-5 year old children with ASD and thirty-two of their typically developing peers of the same ages on several categories of behavior thought to be difficult for individuals with ASD to imitate, including emotional expressions, motor behaviors, and sequences. Imitation was assessed twice using a newly refined imitation test, with approximately 1 week between visits. Imitation was scored for each component of the action imitated for each repetition. Overall, there were differences in imitative ability due to age for every category measured and due to diagnosis for nearly every category, with larger effect sizes for age. When all categories were measured at once, there was a significant age X diagnosis interaction; performance of older children with ASD approximated that of older typically developing children but younger children with ASD were consistently the worst imitators. Odor effects were modest. In general, odor affected imitative performance differently for older and younger children, with younger children benefiting more from odor when imitating more complex tasks. Looking behavior also varied according to age and diagnosis, with younger children with ASD appearing disorganized in their strategy for attending during the imitation task. The other groups appeared similar, with older children with ASD approximating the looking behavior of younger typically developing children. Looking behavior and imitation performance were related. It is suggested that the study of imitation should be broad enough to speak to multiple theoretical perspectives so as to create a more unified description of imitative abilities in individuals with ASD.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Caroline Nell Coffiel
The Association of Waist Circumference With Functional Mobility Among Adults With Obesity and Knee Osteoarthritis
No full textAbstract
Date Presented 3/30/2017
We examined to what extent high waist circumference was linked with decreased functional mobility over 4 yr in adults with knee osteoarthritis (OA). Measuring waist circumference may better stratify the risk of decreased functional mobility among adults with obesity and knee OA.

Applying natural language models and causal models to project management systems
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 97-101).This thesis concerns itself with two problems. First, it examines ways in which to use natural language features in time-varying data in predictive models, specifically applied to the problem of software project maintenance. We attempted to integrate this natural language data into our existing predictive models for project management applications. Second, we began work on creating an easy-to-use, extensible causal modeling framework, a Python package called CEModels. This package allows users to create causal inference models using input data. We tested this framework on project management data as well.by Caroline Morganti.M. Eng
