▼ The present study investigated precollege students' perceptions and attitudes about science, as well as their intentions regarding the continued study of science in the future. The central research questions were: "What is the landscape of Illinois students' attitudes toward science across their school experience?" and "To what extent do school characteristics, including the attributes of classroom teachers, influence student attitudes toward science across the state of Illinois?" To address these research questions, the first phase of this study involved the refinement and validation of a self-report student instrument, the US-ASSASS, which assessed student attitudes toward science based on a theoretical framework drawn from the theories of reasoned action and planned behavior. In the second phase of the study, a representative statewide sample of 1,442 students in grades 5-12 were surveyed about their attitudes toward science using a cross-sectional design. Cross-sectional design was ideal because it allowed data to be collected from students of various ages, and over a large geographical area yielding a wide variance among respondents (e.g., in terms of socioeconomic status). In an effort to allow for equal representation of students across the state, participant schools were selected randomly from each of six geographic regions identified in Illinois. Students completed the 59-item US-ASSASS, along with background items, online. Confirmatory factor analysis was computed using the 1,291 responses collected from students in grades 5 through 10. A five factor structure was refined that was consistent with the underlying theoretical model and the finalized 30-item instrument that demonstrated acceptable statistical fit with a RMSEA of 0.04, a CFI of 0.95, and a non-normed index of 0.95. In addition to student data, information was obtained from 65 of a total of 78 classroom sections and respective schools from which student data were collected. Teachers’ responses to the Science Teacher Survey, along with data compiled from the Illinois Report Card and the National Center for Educational Statistics, allowed for the consideration of several group-level variables (e.g., teacher education, school funding, and community type). These variables were systematically explored and used to create a multivariate multilevel model to characterize students' attitudes toward science and related factors. Inferential statistics, coupled with descriptive statistics, revealed that students’ attitudes toward science declined as they went up their grade levels. A final statistical model was computed from responses collected from students in grades 5-10 that portrays significant declines and other effects. However, the students in the sample who persisted in science until grades 11 and 12 reported high attitudes toward science according to the descriptive statistics presented. It is also positive to note that students' who reported high frequency of talking with family about school and/or a high self-perception of science ability, had… Advisors/Committee Members: Abd-El-Khalick, Fouad (advisor), Abd-El-Khalick, Fouad (Committee Chair), DeStefano, Lizanne (committee member), Osborne, Margery (committee member), Zhang, Jinming (committee member).

▼ Key to achieving more efficient machine intelligence is the capability to analysing and understanding data across different views - which can be camera views or modality views (such as visual and textual). One generic learning paradigm for automated understanding data from different views called cross-view learning which includes cross-view matching, cross-view fusion and cross-view generation. Specifically, this thesis investigates two of them, cross-view matching and cross-view generation, by developing new methods for addressing the following specific computer vision problems. The first problem is cross-view matching for person re-identification which a person is captured by multiple non-overlapping camera views, the objective is to match him/her across views among a large number of imposters. Typically a person's appearance is represented using features of thousands of dimensions, whilst only hundreds of training samples are available due to the difficulties in collecting matched training samples. With the number of training samples much smaller than the feature dimension, the existing methods thus face the classic small sample size (SSS) problem and have to resort to dimensionality reduction techniques and/or matrix regularisation, which lead to loss of discriminative power for cross-view matching. To that end, this thesis proposes to overcome the SSS problem in subspace learning by matching cross-view data in a discriminative null space of the training data. The second problem is cross-view matching for zero-shot learning where data are drawn from different modalities each for a different view (e.g. visual or textual), versus single-modal data considered in the first problem. This is inherently more challenging as the gap between different views becomes larger. Specifically, the zero-shot learning problem can be solved if the visual representation/view of the data (object) and its textual view are matched. Moreover, it requires learning a joint embedding space where different view data can be projected to for nearest neighbour search. This thesis argues that the key to make zero-shot learning models succeed is to choose the right embedding space. Different from most existing zero-shot learning models utilising a textual or an intermediate space as the embedding space for achieving crossview matching, the proposed method uniquely explores the visual space as the embedding space. This thesis finds that in the visual space, the subsequent nearest neighbour search would suffer much less from the hubness problem and thus become more effective. Moreover, a natural mechanism for multiple textual modalities optimised jointly in an end-to-end manner in this model demonstrates significant advantages over existing methods. The last problem is cross-view generation for image captioning which aims to automatically generate textual sentences from visual images. Most existing image captioning studies are limited to investigate variants of deep learning-based image encoders, improving the inputs for the subsequent deep…

▼ The research in this thesis considers the ability of westerners, primarily teachers, to work cross-culturally with indigenous students in four of the settler states, Australia, New Zealand, Canada and the USA. It looks particularly at identity learning as a way in which westerners enhance their understanding and attitudes to another culture. Identity learning, and culture shock as an associated process, is examined in relation to the ideas of border crossing and culture brokerage. A number of issues were raised, some through the literature, which became foci for the research. Examination of border crossing indicated that some westerners were successful as cross-cultural communicators but did not suggest why. Discussions of cultural borders gave rise to their critique as being essentialised but failed to suggest how this was to be overcome. Anthropological models did not give any characterisation to the role of culture broker, although the ethnohistory literature gave some insight. The influence of culture shock on westerners working in indigenous communities in the settler states was not particularly understood nor its relationship to identity learning explored. A qualitative methodology is used involving a series of interviews with eight participants who were considered to be experienced in cross-cultural communication with a background in education. From the interviews a series of narratives were written which revealed their experiences and understandings particularly about their border crossings, culture brokerage and opinions regarding teaching indigenous students and teaching them science. These narratives became the major source of data for analysis. This research shows that many westerners who are successful working in cross-cultural settings value the culture of their indigenous hosts. This is the consequence of enhanced identity learning and can be the result of culture shock. Not all westerners learn to value the other culture and may either leave the community or stay for some other reason. Border crossers are able to think beyond the limitations of an essentialised ‘we and they’ dichotomy and locate themselves in other ways relative to the border. Culture brokerage is a strategy that individuals choose to use, sometimes on the behalf of a government or institution. The characteristics of an effective culture broker are those of a border crosser and this establishes a nexus between border crossing and culture brokerage. Suggestions regarding preparation to teach in indigenous communities reflect the enhancement of identity learning and promotion of border crossing. Preservice training should include experience practicum teaching with indigenous students. Effective teaching of indigenous students could be supported by hiring experienced teachers and extending their stays. All teachers who go to work in indigenous communities need to be aware of culture shock and its possible impact and mechanisms for minimising its impact need to be established through mentoring programs. The context of the students needs… Advisors/Committee Members: Cowie, Bronwen (advisor), McGee, Clive (advisor).

▼ Most previous studies of users with visual impairments (VI) access to the web have focused solely on single user human-web interaction. This thesis explores the under investigated area of cross-modal collaborative information seeking (CCIS), that is the challenges and opportunities that exist in supporting visually impaired users to take an effective part in collaborative web search tasks with sighted peers. The thesis examines the overall question of what happens currently when people perform CCIS, and how might the CCIS process be improved? To motivate the work, we conducted a survey, the results of which showed that a significant amount of CCIS activity goes on. An exploratory study was conducted to investigate the challenges faced and behaviour patterns that occur when people perform CCIS. We observed 14 pairs of VI and sighted users in both co-located and distributed settings. In this study participants used their tools of choice, that is the web browser, note taker and preferred communications system. The study examines how concepts from the "mainstream" collaborative Information Seeking (CIS) literature, play out in the context of cross-modality. Based on the findings of this study, we produced design recommendations for features that can better support cross-modal collaborative search. Following this, we surveyed mainstream CIS systems and selected the most accessible software package that satisfied the design recommendations from the initial study. Due to the fact that the software was not built with accessibility in mind, we developed JAWS scripts and employed other JAWS features to improve its accessibility and VI user experience. We then performed a second study, using the same participants undertaking search tasks of a similar complexity as before, but this time using the CIS system. The aim of this study was to explore the impact on the CCIS process when introducing a mainstream CIS system, enhanced for accessibility. In this study we looked into CCIS from two perspectives: the collaboration and the individual interaction with the interface. The findings from this study provide an understanding of the process of CCIS when using a system that supports it. These findings assisted us in formulating a set of guidelines toward supporting collaborative search in a cross-modal context.

▼ Although consumer emotions have recently become a popular research area in the sensory and consumer sciences, there remains a need for an approach designed to evaluate children’s food emotion experience. The objective of this research was to understand U.S. and Ghanaian children’s emotion responses to food, using words and emojis. In the first part of the research, focus groups were conducted to understand children’s use of emotion words and emojis in response to an array of food consumption experiences, both real and recalled. Through this study, a narrowed list of appropriate words and emojis was identified for further testing with children. This study also revealed that children readily use both emotion words and emojis to characterize their food experiences. The next phase of the research was conducted in three parts, which each included emotion assessments of children’s favorite and disliked foods, as well a common set of eight products selected to elicit a broad range of emotions. First, the emotion set identified in focus group testing was used by children in the United States to assess pictures of foods. The responses from this study were used to further narrow the list of appropriate emojis and emotion words. Second, the reduced emotion set was used by children in the U.S. to assess appearance and post-taste emotions for the products. Finally, a food image test with the reduced emotion set was conducted in Accra, Ghana with schoolchildren. Fielding in Ghana allowed for an exploration of the considerations sensory researchers must make when conducting cross-cultural research with children. Emotion word and emoji usage was similar between U.S. and Ghanaian participants, although some differences were observed. The U.S. studies were compared, revealing the influence of stimulus type on children’s reported emotions. Results from the actual food experiences (appearance, taste) were more positive compared to the evaluation of images. Finally, among Ghanaian and U.S. children, high frequencies of selection for positive emotion words and emojis aligned with a favorite food experience. Overall, this research introduces a new approach to consumer emotion research with children for use both domestically and abroad. Advisors/Committee Members: Delores H. Chambers.

▼ The last two decades have made the Internet a major source for knowledge seeking. Several platforms have been developed to find answers to one's questions such as search engines and online encyclopedias. The wide adoption of social networking services has pushed the possibilities even further by giving people the opportunity to stimulate the generation of answers that are not already present on the Internet. Some of these social media services are primarily community question answering (CQA) sites, while the others have a more general audience but can also be used to ask and answer questions. The choice of a particular platform (e.g., a CQA site, a microblogging service, or a search engine) by some user depends on several factors such as awareness of available resources and expectations from different platforms, and thus will sometimes be suboptimal. Hence, we introduce \emph{cross-platform question answering}, a framework that aims to improve our ability to satisfy complex information needs by returning answers from different platforms, including those where the question has not been originally asked. We propose to build this core capability by defining a general architecture for designing and implementing real-time services for answering naturally occurring questions. This architecture consists of four key components: (1) real-time detection of questions, (2) a set of platforms from which answers can be returned, (3) question processing by the selected answering systems, which optionally involves question transformation when questions are answered by services that enforce differing conventions from the original source, and (4) answer presentation, including ranking, merging, and deciding whether to return the answer. We demonstrate the feasibility of this general architecture by instantiating a restricted development version in which we collect the questions from one CQA website, one microblogging service or directly from the asker, and find answers from among some subset of those CQA and microblogging services. To enable the integration of new answering platforms in our architecture, we introduce a framework for automatic evaluation of their effectiveness.

▼ For refugee students in resettlement in the United States, recognizing culturally-produced knowledge within the context of science learning could legitimate their ways of knowing and position them as stakeholders in the production of scientific knowledge. However, research in science education has been slow to articulate how refugee students’ cultural and experiential knowledge impacts their engagement with scientific practices and language specified by the Next Generation Science Standards (NGSS) (Achieve, 2013). This two-phase research with Karen (first-generation refugees from Burma) parents and students explored first the knowledge Karen parents wished their children to retain as they transitioned into education in the U.S., and second built this knowledge into a science afterschool program for 4th and 5th grade Karen and non-Karen students. Framed by the critical pedagogy of place perspective, this action research explored: 1) what cultural knowledge if any 4th and 5th grade Karen and non-Karen students constructed in a cross-cultural science learning community; and 2) the relationship of that cultural knowledge to how student participants positioned themselves as science learners. Findings from phase one of the research revealed a cultural counter-narrative constructed by Karen parents in resistance to the military dictatorship in Burma. Findings from phase two indicated that Karen students and non-Karen students constructed a hybrid learning space in which they were able to define their own culturally- responsive approaches to inquiry-based science learning, the NGSS cross-cutting concept of energy, and practices such as constructing scientific explanations. An articulation of students’ indigenous knowledge collected through Photovoice was essential to the production of cultural and scientific knowledge within the cross-cultural learning community. Data collected through video recordings indicated that some Karen students leveraged their knowledge of the Karen language to position themselves as agents in science. Signs of emerging agency in science learning indicate that Karen students could develop and use the platform of their own indigenous knowledge to build cultural resilience in education in resettlement.

▼ With the widespread adoption of dynamic web applications in recent years, a number of threats to the security of these applications have emerged as significant challenges for application developers. The security of developed applications has become a higher priority for both developers and their employers as cyber attacks become increasingly more prevalent and damaging.Some of the most used web application frameworks are written in PHP and have become major targets due to the large number of servers running these applications worldwide. A number of tools exist to evaluate PHP code for issues, however most of these applications are not targeted at vulnerability detection. At the same time, Cross-Site Scripting (XSS) vulnerabilities continue to be identified in existing software threatening the security of client data. Providing tools to software developers which can identify these XSS vulnerabilities in code during the development process could reduce the number of vulnerabilities that make it into production code and thus threaten users.This thesis proposes a solution for the problem of identifying non-persistent XSS vulnerabilities in PHP code by demonstrating a system which is capable of finding these vulnerable code paths. This is achieved through the use of static taint analysis, whereby a number of known sources of untrusted data are defined, along with several sensitive sinks which may present a vulnerability if untrusted data is used at these locations. Any data acquired from these taint sources and subsequent propagation of the data is tracked.Code analysis is performed on an Abstract Syntax Tree (AST), an intermediate representation which permits conversion to and from source code. This allows individual line numbers to be tracked for the purpose of clearly displaying taint flow to the user allowing them to visualize how the information flow could result in an unsafe condition and take appropriate action to remedy the vulnerability.This program is capable of analyzing non-object-oriented PHP code and supports most of the common language constructs. Initial testing has shown the program to be highly successful at identifying non-persistent XSS attacks in the supported subset of the PHP language, with future development efforts targeting expanded support for more elements of the language including object-oriented programming.

▼ This dissertation uses ethnographic and design-based research approaches to focus on spaces of environmental science and engineering education as potential sites of intentionally designed hybridity and coordination along a cultural learning. By examining how these spaces afford and constrain learning for culturally and linguistically diverse fifth-grade students as they take part in a coordinated set of learning experiences across multiple settings over a school year, this study addresses the kinds of learning and identification processes that occur as youth engage in science and engineering practices. This set of studies focuses on the social and material features of places, the available social positions, and the actions that are related to learning and identification in order to provide empirical evidence of the key features that facilitate access to new forms of participation and identification in relation to science in young peoples’ communities. Chapter 2 focuses on the development and implementation of an ecologically-grounded survey and interview protocol used to examine the different meanings that young people have for science in relation to the social practices in which they engage. This analysis shows that while young people understand science as being primarily associated with school, they also recognize the ways in which a variety of activities across their lives have the potential to be science-related. The findings in this study are important for the design of equitable formal and informal STEM learning environments that draw on young people’s everyday experiences and understandings of science. Chapter 3 describes a cross-setting approach for supporting and investigating student learning of environmental science in a fifth-grade classroom by focusing on the development of hybrid learning spaces in which youth gain access to new forms of participation and identification in relation to science in their community. Key design features of these environments—narratives of science as multi-voiced and an important tool for communities, youth-authored boundary objects that serve community interests, and access to authentic resources—supported new positionings and identities for youth in relation to science and engineering. In Chapter 4, I examined the implementation of a fifth-grade engineering design curriculum unit to understand how engineering design work has the potential to be an agentic context for engaging youth in scientific and engineering practices that position them as producers of knowledge and useful designs. This study shows that equitable engagement in engineering practices requires specific criteria for design proposals and scaffolded social norms that help students negotiate the relational space of small group work for their own goals. As a set of chapters, this dissertation provides deep and broad accounts of science and engineering learning pathways in and out of classrooms, This work informs the ways in which informal, formal, and hybridized learning spaces can create opportunities for new… Advisors/Committee Members: Bell, Philip L (advisor).

Le management de l’expérience client est un terrain d’étude trop peu exploré en marketing (Lars Grønholdt et al., 2015; Lemon et Verhoef, 2017) et de nombreux professionnels décrivent les enjeux stratégiques, plus spécifiquement, de la conception de parcours client ainsi que la complexité managériale à les concevoir en situation de cross-canal.Notre but, dans une visée prescriptive et normative de la recherche, est d’améliorer, à travers la création d’un outil de gestion, les capacités marketing des managers de parcours client. Nous limitions notre travail doctoral au secteur de la distribution française en cross-canal. La thèse suit la méthodologie de Design Science (Romme, 2003) visant à concevoir un artefact, c’est-à-dire un outil de gestion dont les professionnels peuvent s’emparer pour réduire la complexité du management de l’expérience client. Trois études empiriques qualitatives sont conduites : deux séries d’entretiens individuels et une étude de cas pour tester l’outil conçu.L’artefact développé dans cette thèse comprend un ensemble de concepts, une méthode de travail ainsi que sa réalisation effective appelée instanciation, fondée sur les résultats des deux premiers terrains. Nous montrons que le choix théorique de considérer le parcours client comme une coproduction de ressources et de fonder la conception de parcours sur une structure modulaire permet d’améliorer les capacités marketing et d’en développer de nouvelles, contribuant ainsi au savoir managérial mais aussi académique car notre recherche explore, d’un point de vue théorique, les ressources engagées par le client et l’entreprise, ainsi que les capacités marketing nécessaires pour le manager et leurs dynamiques.

Customer experience management is less explored in marketing (Lars Grønholdt et al., 2015; Lemon and Verhoef, 2017) and many practitioners describe strategic issues, and specifically, the managerial complexity to design of customer journey in cross-channel location.Our goal in our prescriptive and normative research, is aiming to improve, through the creation of a management tool, managers’ marketing capabilities. We restrict our doctoral work to French cross-channel retail. The thesis follows the Design Science Methodology (Romme, 2003) aimed at designing an artifact, which is a management tool that professionals can take to reduce the complexity of customer experience management. Three qualitative empirical studies are conducted: two series of interviews and a case study to test the artifact.The artifact developed in this thesis includes a set of concepts, a method and its effective realization called instantiation, based on the results of the first two interviews. We show that the theoretical choice to consider the customer journey as a co-production of resources and the design of customer journey as a modular structure allows to improve actual marketing capabilities and develop new ones, thus contributing to managerial knowledge but also academic because our research explores, from a theoretical point of view, the resources…

▼ One of the major problems experienced by wireless multi-hop networks is the intermittent network connectivity, which is a consequence of fluctuating link quality due to signal fading.Antenna array technology has been proposed to alleviate the problem of signal fading,and it provides significant performance increase on a single link. However, translating this link-level performance increase to an end-to-end gain in multi-hop networks is not straightforward; a cross-layer design is necessary to efficiently facilitate this translation. In this dissertation, we present cross-layer design approaches for providing end-to-end performance increase in multi-hop networks using antenna arrays. Each approach is designed to utilize a special capability with antenna arrays. Using antenna arrays, nodes can increase the signal strength in a specific direction;i.e., perform directional communications. Using directional communications in a multi-hop network requires nodes to periodically update the directions of their neighbors, which introduces an overhead. We propose topology control algorithms that enable the use of directional communications in multi-hop networks with bounded overhead. The bounds provided by our Low Degree Spanner (LDS) and Distributed LDS (D-LDS) algorithms are near-optimal. Space-Time Block Coding (STBC) with antenna arrays (referred to as MIMO-STBC) offers significant robustness to fading without an overhead at the higher layers.Robust MIMO-STBC links can also provide performance improvements at the higher layersby the design of proper protocols. Such a design necessitates an accurate representation of the MIMO-STBC link behavior. To date, simplistic representations have been used. We design an accurate representation of MIMO-STBC communications, which we show to have a high fidelity to the MIMO-STBC communications in practice.Antenna arrays also facilitate the spatial multiplexing of signals, allowing a node to transmit and receive multiple signals simultaneously. In a multi-hop network, spatial multiplexing enables receptions from multiple concurrent transmitters. However, such a reception is successful only ifboth the number and the strength of concurrent transmissions is controlled by a higher-layer mechanism. We design topology control algorithms for activating a maximal number of communications simultaneously, while ensuring that every communication is successful with high probability.

Η γνωστική διάσταση επιστήμης και τέχνης αποτελεί έναν από τους σημαντικότερους λόγους που καθιστά δυνατή την ιδιαίτερη επικοινωνία που τα δύο πεδία αναπτύσσουν μεταξύ τους. Η γνώση, ως θεμελιακό δομικό στοιχείο τους, συμβάλλει στην ευρύτερη αλληλεπίδρασή τους, αλλά και στη δυνατότητά τους να είναι συμπαραγωγοί και συνδιαμορφωτές κοινών δημιουργιών. Επιπλέον ερμηνεύει τη δυνατότητά τους να συμπράττουν στην εκπαιδευτική διαδικασία. Η διαθεματική προσέγγιση της γνώσης παρέχει μια σημαντική ευκαιρία για συνεργασία των δύο πεδίων και την προώθηση μιας ολιστικής εκδοχής της, που οδηγεί στη συγκρότηση από τον/την μαθητή/μαθήτρια μιας προσωπικής θεώρησης για τον κόσμο και τα φαινόμενά του. Στη σχολική πρακτική ωστόσο η τέχνη υποβαθμίζεται και συχνά χρησιμοποιείται ως εργαλείο προώθησης των στόχων που θέτει η επιστήμη, με συνέπεια τη μη ισόρροπη συμμετοχή των δύο περιοχών κατά την διδακτική πράξη και την άρση εν τέλει της αυθεντικής διαθεματικής προσέγγισης της γνώσης.

The production of the work of art and scientific discourse building are facts of a long evolutionary process, not irrelevant to the biological, mental and social maturity of mankind. The cognitive dimension of science and art is one of the major reasons for allowing the specific communication between the two fields. Knowledge, as their fundamental structural component, contributes to wider interaction and in their ability to being co-producers of common creations. Moreover it interprets their ability to collaborate in the educational process. The cross-thematic approach provides an important opportunity for collaboration between the two fields and it promotes a holistic version of knowledge that can lead pupils to the formation of their point of view about the world and its phenomena. In school practice, however, art is downgraded and often it is used as a promotion tool for science objectives. As a result the participation of the two fields in the lesson is unbalanced and finally the authentic Cross-thematic approach of knowledge is revoked.

▼ It is clear that we live in an age when a lingua franca is essential to address many regional and global environmental and social problems. It is also evident that there is at present, and will continue to be for the foreseeable future, a heavy dependence on English as the principal international lingua franca. This qualitative research focused on the processes and problems involved in cross-linguistic communication concerning global environmental issues, and their potential impacts on international collaboration. The goal was to illuminate ways in which international environmental outreach programs can become more effective in promoting understanding of the environmental and cultural issues involved, as well as improve collaboration and cooperation in the generation of solutions to environmental problems. The first research stage explored the experiences of individuals from 16 countries who were involved in international education, outreach and communication (EOC) about polar issues during the International Polar Year 2007-2008 (IPY). This was an in-depth investigation of how the IPY EOC programs functioned in relation to multilingual issues, with the aim of identifying potential commonalities and differences about what worked well in different cultural, linguistic and social contexts. Interview questions centred on interactions related to language and culture during group meetings, and the reasons for success (or lack of success) in international EOC programs that were conducted over a four-year period. Interviewees were also asked for their opinions on the positives and negatives of using English as a lingua franca to communicate on issues such as climate change, and for their suggestions about effective ways to communicate about these issues across cultural and linguistic boundaries. Analysis of the data obtained was used to refine additional research questions that were investigated in more depth in the next stage. The second stage broadened the focus to consider how the initial findings might benefit other global environmental EOC initiatives. Teachers and adult facilitators who were identified during the IPY interviews developed a joint school project with classes in Brazil, Chile, Greenland and Malaysia. Using an action research approach, they identified issues that were relevant and interesting to them, and worked collaboratively to seek solutions. My research in this stage focused principally on the communication strategies used by both teachers and students as they tried to work with peers in the other countries. I also investigated the impacts of English-language domination of scientific research on science education and communication at both international and local levels. The study concluded with a summary of some of the common issues identified, outlined some possible strategies for their resolution, and suggested areas for further research. This information may help others plan and deliver more effective international and intercultural programs in the future.

▼ Mercury has proven to be a unique natural laboratory for space plasma processes. Mercury’s magnetosphere is formed by the interaction between its intrinsic planetary magnetic field and the supersonic solar wind. The structure of Mercury’s magnetosphere is very similar to Earth’s; yet the results from the MESSENGER mission to Mercury have shown that the spatial and temporal scales of magnetospheric processes are very different at Mercury. In this thesis, we analyze in situ observations from the MESSENGER spacecraft to characterize and understand the dynamic physical plasma processes occurring in Mercury’s magnetosphere. We identified and analyzed 345 plasma filaments in Mercury’s northern magnetospheric cusp to determine their physical properties. Cusp plasma filaments are magnetic structures that are identified on the basis of their characteristic 2‒3 seconds long decrease in magnetic field intensity. Our analysis indicates that these cusp filaments are cylindrical flux tubes filled with plasma, which causes a diamagnetic decrease in the magnetic field inside the flux tube. MESSENGER observations of flux transfer events (FTEs) and cusp filament suggests that cusp filaments properties are the low-altitude extension of FTEs formed at Mercury’s dayside magnetopause. We examined 319 central plasma sheet crossings observed by MESSENGER. Using a Harris model, we determined the physical properties of Mercury’s cross-tail current sheet. Analysis of BZ in the current sheet indicated that MESSENGER usually crossed the current sheet sunward of the Near Mercury Neutral Line. Magnetohydrodynamics-based analysis using the MESSENGER magnetic field and plasma measurements suggests that heavy planetary ions and/or ion temperature anisotropy may be important in maintaining radial stress balance within Mercury’s central plasma sheet. We report the observation of significant dawn-dusk variation in Mercury’s cross-tail current sheet with thicker, lower plasma β dawn side current sheets than the dusk side. Using the Harris current sheet model, we determined the peak current sheet current density and reported an asymmetry pattern for peak current density consistent with observed asymmetries in current sheet thickness. We propose that enhancement of heavy ions in the dusk side current sheet, due to centrifugal acceleration and gradient-curvature drift of ions from the cusp and current sheet, provides a partial explanation of the dawn-dusk current sheet asymmetries observed in this study. Furthermore, our results are consistent with earlier studies on reconnection-related structures and phenomenon, which suggest that the asymmetries observed in this study are associated with the asymmetric nature of magnetotail reconnection at Mercury. We also report the possible observation of an Earth-like substorm current wedge in the near-Mercury magnetotail. We calculate the total current in the Hermean substorm current wedge and found that the current close via the conductive planetary core. The current closure mechanism may be similar to the Region… Advisors/Committee Members: Jia, Xianzhe (committee member), Slavin, James Arthur (committee member), Kushner, Mark (committee member), Le, Guan (committee member), Raines, Jim (committee member).

▼ This thesis presents the measurement of the vector boson pair W^+W^- production cross section in proton-proton collisions at the center-of-mass energy sqrt(s) = 8 TeV. The leptonic decay channels of the WW+ll for l=(e,mu) are analyzed using data corresponding to 20.3 fb^-1 of integrated luminosity collected by the ATLAS detector in 2012 at the Large Hadron Collider at CERN (in Geneva, Switzerland). The experimental signature of this measurement is two energetic isolated leptons (e^+e^-, mu^+mu^-, e^+mu-, e^-mu^+) and associated large missing transverse energy (due to neutrinos in final states). A total of 6636 WW+ll candidate events is selected in ATLAS data with an estimation of 1547+/-28 background events from non-W^+W^- production processes. The measured total production cross section is 71^(+1.1)_(-1.1)(stat)^(+5.7)_(-5.0)(syst)^(+2.1)_(-2.0)(lumi) pb,, which is comparable with the theoretical prediction of 63.2^(+2.0)_(-1.8) pb calculated with NNLO QCD and NLO EW corrections. The anomalous triple-gauge-boson couplings (WWZ and WWgamma) could signal new physics beyond the Standard Model at much higher energy scales compared to the directly detectable mass scale at the LHC. An effective Lagrangian is used to generalize the anomalous triple-gauge-boson couplings to describe the W^+W^- productions at the LHC. These anomalous couplings can be experimentally probed by comparing the leading lepton transverse momentum spectrum with the theoretical predictions in different triple-gauge-boson coupling space. No observation of deviations from the Standard Model predicted couplings is found by a maximum likelihood fitting of the leading lepton transverse momentum. Therefore, the most stringent limits to date on the anomalous triple-gauge-boson couplings are set from this analysis.

▼ The Organ group used microwave irradiation as a means of heating flowed chemical reactions in the development of a microwave-assisted continuous-flow organic synthesis (MACOS) system, to combine the benefits of flow reactions and the effective heating of microwave radiation. MACOS was well suited to the use of heterogeneous catalysts contained within the reactor capillaries, and metal films proved to be effective to not only catalyze reactions, but also to act as a heating source. Unfortunately, the heating of bulk metal films under microwave irradiation was hard to control, leading to intense over-heating of reactions and destruction of the metal films. Transition metal-loaded heterogeneous catalysts immobilized on microwave-transparent silica supports were prepared. The supported catalysts also act as a mixer within the flow channels to prevent laminar flow and allow for high catalyst surface area. The in situ palladium nanoparticle-loaded silica macrospheres were used to catalyze Heck cross-coupling reactions in MACOS, providing good product yield, and can be recycled several times without appreciable decrease in product formation. Dithiocarbamate-functionalized ligands were prepared and used to form amphiphilic transition metal complexes to attempt to selectively load metals at the surface of silica macrospheres. Some selectivity for incorporation of the metal complexes towards the outer surface of the macrospheres was obtained, however, there was a penetration depth of metals into the interior of the macrospheres, and the complexes were not fully characterized. Inorganic-organic hybrid macrospheres were prepared containing functional groups that could coordinate desired transition metals selectively on their surface. These inorganic-organic hybrid catalyst supports were also used to perform Heck cross-coupling reactions in MACOS. Calcination of these metal-loaded macrospheres yielded silica macrospheres with palladium nanoparticles loaded selectively on their surface. The inorganic-organic hybrid macrospheres were able to catalyze the Heck cross-coupling of aryl iodides in MACOS. They were re-usable without significant decrease in product conversion. The calcined macrospheres with palladium nanoparticles loaded selectively on their surface were able to catalyze the Heck cross-coupling of aryl iodides in MACOS, but significant leaching of the catalyst from the support was observed.

▼ What consequences arise as a result of repeated control of the legislature by the same party or coalition? Are incumbent parties less likely to lose an election the longer they remain in power? Furthermore, as parties remain in power longer and longer, do the factors which electoral scholars have proposed influence elections have less of an impact on election outcomes? The purpose of this project is to examine the electoral impact of repeated control of the legislature by the same party or ruling coalition. In this project, I argue that the length of time an incumbent party or coalition has maintained control of the legislature is a critical consideration for scholars interested in studying elections. In doing so, I hope to develop a better understanding of elections, the factors which influence election, and the mechanisms by which these factors affect election outcomes. Central to this project is the phenomenon I call party duration. I define party duration as the number of years the incumbent party has maintained control of the legislature in unicameral legislatures or the lower house in bicameral legislatures. This is the party that has secured enough seats to control the legislature independently in cases where a single party controls the legislature, or the party that serves as the largest party in the ruling coalition that controls the legislature in cases where a single party does not control the legislature by itself. Using cross-sectional time-series analysis to study a novel dataset, I show that not only does increasing party duration decreases the likelihood that an incumbent party will lose an election, controlling for various other factors, but I find evidence that party duration also affects the effect of other variables which influence elections. Specifically, I focus on the impact that the length of party duration has on the effect of economic conditions on the incumbent party's performance in elections. These findings highlight the importance of party duration, a variable which has previously not received attention from electoral scholars Advisors/Committee Members: Reisinger, William M.

▼ The purpose of this study was to explore the experiences of classroom teachers who participated in a science-focused study abroad during their time as a preservice teacher and to explore how they are using their study abroad experiences in science curriculum planning and in classroom instruction. This study is guided by two research questions: 1) what are the study abroad experiences that have influenced classroom teachers; and, 2) how do classroom teachers incorporate study abroad experiences into science curriculum planning and instruction in the classroom? Participants were two in-service science teachers from schools located in the Southwestern United States. The participants were enrolled in the course, Environmental Science and Multicultural Experience for K – 8 Teachers offered through the Department of Educational Leadership, Curriculum and Instruction during their time as preservice teachers. The course included a two-week study abroad component in Costa Rica. Participants spent their mornings observing a monolingual, Spanish-speaking elementary classroom followed by a faculty-led multicultural seminar. Afternoons during the study abroad experience were dedicated to field science activities such as quantifying plant and animal biodiversity, constructing elevation profiles, determining nutrient storage in soil, and calculating river velocity. Throughout the course students participated in science-focused excursions. A cross case study design was used to answer the two research questions guiding this dissertation study. Data collection included participant-created concept maps of the science experiences during the study abroad experience, in-depth interviews detailing the study abroad experience and classroom instruction, and participant reflective journal entries. Cross-caseanalysis was employed to explore the uniqueness of each participant’s experience and commonalities between the cases. Trustworthiness was established by utilizing multiple sources of data, member checking, documenting the process of identifying themes from findings, and peer de-briefing. Four themes emerged via data analysis, they include: (1) experiencing science in Costa Rica, comprised of the categories of facilitated science experiences, collaborative grouping, and science stressors; (2) studying abroad in Costa Rica, containing the categories Costa Rica is your oyster, background of Costa Rica, foreground of Costa Rica, atmosphere of Costa Rica, and Costa Rican culture; (3) transferability of science experiences including the categories disposition of teaching, pedagogical knowledge, what you teach, and for whom you teach; and (4) the multicultural classroom made up of the categories Costa Rican classroom struggles, positive Costa Rican classroom climate, transferability of instructional approaches, and developing cultural competency. Implications for study abroad decision-makers and stakeholders are included. Additionally, recommendations for future research are also described.

▼ Objective: This study was conducted to investigate the relationship between hip bone mineral density (BMD), fat free mass (FFM), fat mass (FM), and total body mass (TBM) and the extent to which these relationships were modified by various confounding factors. The cross-sectional analysis included 262 healthy females (mean age 41.6±3.0 years). Methods: BMD of the hip and body composition were assessed by the Hologic 4500W dual energy x-ray absorptiometry (DXA) system. Total and intensity of physical activity (PA) were objectively measured using an Actigraph accelerometer. Dietary calcium and vitamin D from food and beverages, as well as from supplements, were measured separately using the Block food frequency questionnaire. Menopause status and prescription bone drug use were measured by a questionnaire. Results: The relationship between FFM and hip BMD was strong and robust (F=24.5, P<0.0001). Using the pooled standard deviation revealed a large effect size of 1.2 when comparing hip BMD of women with low FFM and high FFM. Potentially confounding variables, considered individually and collectively, did not change this relationship. The association between FM and hip BMD was also substantial (F=9.9, P<0.0001) and remained significant when controlling for all potentially confounding variables, except differences in FFM. The relationship between TBM and hip BMD was also strong and dose-response (F=21.5, P<0.0001) and remained significant, except when differences in FFM were controlled. Conclusion: The relationships between body mass (total, fat, and fat free) and BMD of the hip in middle-age women are strong and significant. The associations are not influenced by differences in age, height, menopause status, calcium or vitamin D intake, volume or intensity of PA, or the use of bone enhancing prescription drugs. The findings suggest that women with low body mass, particularly low FFM, tend to have low hip BMD and there is little that can be done to change this association.

▼ Ice accumulation is a major engineering challenge in many fields including aerospace, power generation, transportation, and infrastructure. A variety of solutions are being researched to address this challenge. Perhaps the most promising method of combating ice accumulation is by applying coatings with low values of interfacial ice adhesion strength, τice. Icephobic materials are those with ice adhesion below 100 kPa, and it has been shown that passive delamination can occur on surfaces with τice below 20 kPa. While various low adhesion surfaces have been prepared, durability concerns pervade applications where surfaces experience repeated icing or freeze-thaw cycles, mechanical abrasion, and particulate erosion. The present thesis explores methods of improving the durability of state-of-the-art icephobic materials in order to make them more suitable solutions to ‘the icing problem.’ Ice adhesion was measured using in-house load cell and centrifugation methods, allowing for the direct comparison of τice values between the materials developed. Various ways of improving the durability of icephobic surfaces were identified, including the stabilization of slippery lubricant-infused porous surfaces (SLIPS) via polymer cross-linking at the interface, copolymerization of commercial poly(dimethylsiloxane) resins with acrylate / styrene monomers yielding highly cross-linked network copolymer coatings, and lowering ice adhesion on commercially available adhesive films by introducing areas of substrate-film detachment. A collaborative study of femtosecond laser micromachining done with McGill University is also included which showed the cross-link density dependence of threshold fluence, and the varied surface morphologies that could be accessed by these means. These studies show effective methods of influencing icephobic material durability using straightforward methodologies and will inspire new investigations toward creating more durable icephobic materials that can alleviate concerns with ice accumulation for people that live in cold climates. Our investigations and proposed work show that cutting-edge research in this field can be done at Western, making Canada a viable leader of global anti-icing research.
