A Combined Molecular and Morphological Revision of Cirrospilini LaSalle (Hymenoptera: Eulophidae) with a Focus on Zagrammosoma Ashmead and Cirrospilus Westwood

Perry, Ryan Kevin University of California, Riverside ProQuest Disse 2020 해외박사(DDOD)

The tribe Cirrospilini (Hymenoptera: Chalcidodea: Eulophidae) is revised in a combined molecular and morphological phylogenetic context, using ribosomal (18S, 28S, ITS2) and mitochondrial (COI) data, and scoring specimens for morphological characters. Twenty genera are now recognized in the tribe. Colpoclypeus Lucchese and Trichospilus Ferriere are included in Cirrospilini, while Cirrospiloidelleus Girault is removed. Melittobiopsis Timberlake is also removed from Cirrospilini, and raised to Melittobiopsini Perry n. tribe., sister to Eulophini Ashmead. Cirrospilus Westwood is revised and is split into 6 morphologically distinct genera: Atoposoma Masi stat. rev., Burkseus Perry, Cirrospilus str. s., Gyrolasella Girault stat. rev., Pseudozagramma Perry n. gen., and Vagus Perry n. gen. The new synonymy of Semielacher Boucek under Cirrospilus is proposed. The first worldwide key to all genera is presented, as well as distribution maps, and extensive specimen, host, and host plant records. Zagrammosoma Ashmead is molecularly revised using ribosomal (28S, ITS2) and mitochondrial (COI) data, with 24 species now recognized, including descriptions of 9 new species. A worldwide key, distribution maps, and image plates of all species are provided.

Partition experimental designs for sequential processes

Perry, Leonard Albert Arizona State University 2000 해외박사(DDOD)

Processes exist in manufacturing, chemical sciences, physical sciences, or just about any place there is development of a product. The output quality characteristics of a product depend not only on the effect of the factors in the current process, but the effects of factors from preceding processes. Design of Experiments (DOX) provides a systematic approach to study the effects of multiple factors on process performance by offering a structured set of analyses in a design matrix. Little research has been done in applying experimental design methods to multiple sequential processes. The research objective is to create an experimental design capable of handling a serial process consisting of sequential processes that possess several factors and multiple responses. The proposed design expands the current experimental designs to incorporate two processes into one partitioned design. The advantages include time reduction in performing the experiment, a decrease in the number of experimental runs, and better understanding of the current serial process performance.

The ripple effect: Social network dynamics, social location, and strategies of interaction in mental illness careers

Perry, Brea L Indiana University 2008 해외박사(DDOD)

Social networks are dynamic in nature, characterized by ebbs and flows in the level and quality of interaction that correspond to important changes in the lives of individuals. Disruptive events and transitions have been theorized to restrict access to existing network ties and provide opportunities for new associations and alter network structure, altering network structure, function, and content in meaningful ways. The main objective of this research is to capture the interplay between the dramatically changing circumstances in individuals' lives, the activation of social resources, and the evolution of networks. Plainly, the central question is 'how and why do social networks evolve in response to disruption and uncertainty?' This research is fundamentally about how crisis requires people to rethink and respond to changes in their social interaction patterns, and reorganize personal social networks challenged by escalating needs, changes in social location, and the stigma attached to mental illness. Using the Indianapolis Network Mental Health Study (INMHS), I follow the social network experiences of 171 "first-timers," that is, individuals making their first major contact with the largest public and private treatment centers in the city. Data reveal that crisis reverberates through the social network, initiating significant changes in network size, functionality, and level of membership turnover. When we experience crisis, support needs increase, in turn shaping interactions in ways that have important implications for the stability of social networks. Moreover, crisis in one life domain tends to lead to disruptive transitions in other domains, as well. Seldom considered, but of great consequence for "first-timers," are changes in social structural location, including residential and relationship instability, jeopardize existing ties and exacerbate the level of disruption in social ties. Network disruption then affects how networks function, as new social ties do not easily replace longstanding friends and family. In short, traumatic events, like illness, in the lives of individuals set into motion a ripple effect that has pervasive consequences for social life. In sum, this research addresses the classic sociological tension between structure and agency. That is, it illustrates that individuals are not unobtrusive observers of social network instability or passive recipients of network resources. Rather, individuals early in their experiences with mental health treatment are often active and occasionally strategic agents who shape and maintain their social networks in ways that help them meet their needs and cope with uncertainty and crisis. However, people's ability to construct their networks and mobilize resources is constrained by structural factors, often out of their control, including disruptive events that force transitions into and out of the different social roles, statuses, and group memberships that accompany mental illness.

A question of voice and an examination of an-Other in the "Lacnunga": A rhetorical recovery

Perry, Susan P Texas Woman's University 2001 해외박사(DDOD)

The <italic>Lacnunga</italic> reaches us, some one thousand years after its compilation, as a medical text and an early form of technical writing created by a healer skilled in <italic>Lœcecrœft</italic>. This study creates additional understanding of the audience, the <italic>Lacnunga </italic>'s oral and literate features, the manuscript's metaphors, rational and superstitious healing, and gender features in the <italic>Lacnunga</italic>. The <italic>Lacnunga</italic>'s layers interweave, emerge, and later submerge, serving as architect, informing, clarifying, and unveiling the other strata. Each is a component of the <italic>Lacnunga</italic>'s overall manuscript. Looking at this multi-voiced document using Bakhtin's paradigm for textual analysis reveals the strata differently than Grattan and Singer do in their study <italic>Anglo-Saxon Magic and Medicine</italic>. Their analysis deals with internal evidence which reveals the historical influences embedded in the manuscript. Their discussion of this “common-place book” identifies medical knowledge which was concurrent with or predated the <italic> Lacnunga</italic>. Further, they discuss the magical, pagan, and Christian influences on the text. This study has identified other forms of influence, while at the same time working with the narrator and the voice of an-Other which is intrinsic to the manuscript. Broadly speaking, this study has two goals. As a work of scholarship, it seeks to recover the internal voice of an-Other, a voice which contributes to an additional inclusive understanding of the <italic>Lacnunga</italic>. The second goal examines authorship through gender-related study, seeking to examine the text through evidence, circumstantial as it is, in hopes of instigating further discussion and research on the <italic>Lacnunga</italic> as a possible example of feminine contribution to medicine. The working paradigm for the study has been Bakhtin's theory of <italic>heteroglossia</italic>. An examination of the narrator and an-Other which exists as a dialogic entity within the text uncovers the easily identifiable voice in each chapter, a voice which dialogues with and receives aid towards rhetorical recovery by an internal, weaker voice. This concept is intrinsic to this study and to a method useful for identifying voices which are entrenched in the text, voices which add new ways of looking at the Lacnunga.

Imitatio Christi: Models for Christian living in early modern England

Perry, Nandra L The University of North Carolina at Chapel Hill 2003 해외박사(DDOD)

This dissertation explores the relationship of the traditional devotional paradigm of <italic>imitatio Christi</italic> to the theory and practice of imitation in early modern English literature. Drawing upon a wide variety of genres—16th-century treatises on poetry, 17th-century lyrics, martyrologies and spiritual biographies—my project frames <italic>imitatio Christi </italic>, broadly construed here as the pursuit of ideal Christian subjectivity through self-abnegation, within the broader literary discourse surrounding the construction and manipulation of identity through <italic>imitatio</italic>. More specifically, it treats English Protestant anxieties concerning the adaptation of “Catholic” devotional models like the <italic>imitatio Christi </italic> as a window onto imitations ambivalent role in fashioning a self-consciously English (implicitly Protestant) aesthetic from the literary heritage of pre- and Counter-Reformation Europe. Using <italic>imitatio Christi</italic> as a guiding motif, each chapter treats the theological framings of subjectivity available within particular English religious genres as a negotiation between theology, generic convention, and specific material and political pressures. Divided into three broad sections (hagiography and spiritual biography, treatments of religious imagery and the sacraments, and an opening section on the relationship between secular <italic> imitatio</italic> and <italic>imitatio Christi</italic>) the project employs a “snapshot” approach to the <italic>imitatio Christi</italic> at work across the early modern period. By employing this strategy, I hope to avoid the narrowness of micro-history while minimizing the totalizing effect of a chronological narrative. By taking seriously the demands religious texts make on their readers, I hope to construct models of subjectivity sensitive to the political and material aspects of early modern religious experience while remaining equally sensitive to what I believe to be the irreducibly “religious” orientation of the early modern subject. Furthermore, by contextualizing both Catholic and Protestant devotional texts and practices within the broader literary culture, I hope to more accurately reflect the fluidity of the devotional economy in early modern England and to suggest new and potentially productive categories of analysis that resist overly neat distinctions between Catholic and Protestant, sacred and secular, literary art and cultural artifact.

Mathematical analysis of two monomer systems of frontal polymerization

Perry, Michael F Northwestern University 2003 해외박사(DDOD)

Frontal polymerization is a technique for converting monomer into polymer via a self-propagating reaction wave. Polymers can be manufactured by using one or more monomers; however, polymers formed with two or more monomers are advantageous because the polymer can assume specific important qualities. In this thesis, mathematical models for free-radical binary frontal polymerization and free-radical frontal copolymerization, methods in which polymers are formed using two different monomers, are developed. Through simplifying assumptions, the equations are solved both analytically and numerically, and important characteristics of the process, such as the propagation speed of the wave, the final temperature in the reaction front, and the final monomer concentrations, are studied. The analytic solution is compared to the numerical solution and to experimental results, whenever possible, to demonstrate agreement between the results. Parameters of the reaction are examined to determine which ones most influence the aforementioned characteristics. Stability of the polymerization front is also investigated.

Shaping self-concepts: Ability grouping and middle school students

Perry, S. Marshall Stanford University 2007 해외박사(DDOD)

This study examines the development of academic self-concept within the context of ability grouping. It explores how academic self-concept differs within and between ability grouped and heterogeneous classes with consideration to classroom atmosphere and the placement process. At the selected middle school, four classrooms were examined: two mixed ability sixth grade classrooms, a low ability seventh grade class, and a high ability seventh grade class. Quantitative and qualitative methods were employed. Students responded to a Likert-scaled questionnaire in the fall and spring of an academic year. A subsample of the sixth graders responded to the questionnaire a third time, in the fall of their seventh grade. Additionally, the teachers and a stratified sample of students were interviewed, and each classroom was observed several times. Analysis of the fall data supported labeling effects in that the seventh grade high-ability group scored significantly higher in several areas of academic self-concept than those in the low-ability group. While the ability groups differed significantly in several items, the high- and low-standing sixth graders that were not grouped were notably similar. When the subsample of students entered ability grouping in seventh grade, the high- and low-standing student scores diverged markedly in several areas of academic self-concept. Analysis of the spring data, however, supported reference group and teacher effects in that the academic self-concept scores of the two seventh grade ability groups tended to converge. In the high-ability group, students below the classroom academic mean tended to have less positive scores by the end of the year. For the low-ability group, the inverse was sometimes true, but for many items, the students near the bottom academically had raised scores in the spring, suggesting teacher effects. Qualitative data illustrated how high- and low-ability group students realigned their aspirations and motivations in an attempt to protect the self-concept. Students in the low ability group tended to place less emphasis on doing well and more on staying out of trouble. While placing more emphasis on intellectual effort, high-ability group students were defensive about privilege and uncomfortable about ethnicity. The study illustrates the complex relationship between self-concept and ability grouping.

Assessment of adult student and instructor perceptions of classroom environment: A tool to improve teaching in adult degree completion programs

Perry, Barbara A The University of Memphis 2005 해외박사(DDOD)

This study seeks to determine if adult student and instructor perceptions of the actual and preferred psychosocial classroom environments of classes in a business administration degree completion program differ. In addition, the study attempts to ascertain if a significant difference exists between students' perceptions of the actual classroom environment of full time instructors and adjunct instructors. Student and instructor perceptions of the classroom environment are measured by use of Fraser and Treagust's (1986) Classroom and University Classroom Environment Inventory (CUCEI). Consequently, the investigation is grounded in a person-environment fit theoretical framework and reflects previous classroom and university environment research. The sample consists of 191 students and 20 instructors participating in a business administration degree completion program at a small liberal arts university in the middle south region of the United States. Descriptive statistics, MANOVA procedures, dependent Mests and independent t-tests have been calculated. The inquiry provides evidence of statistically significant differences between means for adult student and instructor perceptions of the actual and preferred classroom environments of the classes studied in this business administration degree completion program. In addition, the study demonstrates that the adult student participants perceive a more positive classroom environment in the classes taught by adjunct instructors than that of full-time instructors. The results of the study suggest: (a) the utility of the CUCEI as an assessment tool for adult degree completion program classroom environments since it provides feedback beyond typical classroom evaluations; (b) the usefulness of the CUCEI as an assessment tool for instructors since it provides feedback indicating the gap between adult student and instructor perceptions of the actual and preferred classroom experiences; (c) a need for a rigorous selection process for instructors in adult degree completion programs to ensure participation of instructors with the ability to critically reflect on established classroom behavior and to make changes to meet adult students' needs; (d) a need for institutions which offer degree completion programs to provide formal training for adult educators to instill andragogical views of teaching; and (e) a need for further study perceptions of classroom environments in adult degree completion programs to improve program teaching and effectiveness.

Perceptions of accommodations in the success of college students with learning disabilities and/or attention-related disabilities: A study of experiences at one university

Perry, Tara Beatrice Washington State University 2005 해외박사(DDOD)

A growing number of students with learning disabilities (LD) and/or attention related disabilities have entered colleges and universities. They have encountered new accommodation procedures that differ from their high school experience. Such accommodations have either contributed or hindered their academic success. Understanding the students' successes and challenges was essential to developing support services that could meet their needs. This qualitative study focused on students' perceptions of their college experiences as well as the context of those experiences. Due to the limited research regarding specific accommodations that contribute to student success in college, this descriptive study examined their university and classroom accommodation in regards to their college success. The researcher implemented a qualitative approach to answer critical questions that capture the detailed lived experiences of the participants. Flyers were advertised to request volunteers who had a documented LD and/or attention related disability documented at the disability support services on campus. Volunteers across academic standings were selected to be interviewed based on having one or more of the disabilities noted. In order to capture the experiences of participants, the researcher conducted 19 one-on-one, face-to-face interviews with 10 students and nine support service providers. The students with LD and/or attention related disabilities were full-time students enrolled in a four-year university. Moreover, the researcher collected artifacts highlighting how students are accommodated as well as reviewed their documented disability files. Five research questions were used to understand the college student experience. From the data collected the researcher coded themes, combined like categories, looked for trends within the data, discussed new findings, and compared the findings to what has been discussed in the literature. The results of this study could bring about discussion of key issues facing students with LD and/or attention related disabilities and policy makers could conduct further studies in this area. Findings from this study could inform students, university professors, administrators, staff, and disability resource centers on how to foster equity within the college setting and adhere to laws for student success. This study will be discussed in five chapters: Introduction, literature review, methodology, data analysis and results, and discussion.
