Religion And Movement Activism In 1960s Chicago, D. Trevor Burrows

Open Access Dissertations

This dissertation examines the place of religion within various forms of movement activism in Chicago’s 1960s. Although scholars have documented religious participation in the period’s civil rights and peace movements, less attention has been paid to how religious leaders and institutions fit into the complicated institutional networks that drove such activism, or how religious participation was perceived by activists themselves. This is especially true of student activists whose relative lack of religious affiliation has often been interpreted as a lack of interest in religion altogether. This dissertation argues that the category of religion occupied a particular place and performed a …

Proteomics Strategies To Develop Proteins Of Post-Translational Modifications In Plasma-Derived Extracellular Vesicles As Disease Markers, I-Hsuan (Blair) Chen

Open Access Dissertations

Blood tests, which are the most wide spread diagnosis procedure in clinical analysis, apply blood biomarkers to categorize patients and support treatment decisions. However, existing biomarkers often lack specificity and are far from comprehensive. Mass spectrometry-based proteomics allow users to characterize plasma protein in great depth and has become a powerful tool in the biomarker discovery area. However, because of the extremely high dynamic range of plasma, being able identify thousands of plasma proteins using methods such as Liquid chromatography-tandem mass spectrometry (LC-MS/MS) remains a challenge. Furthermore, recent discoveries of extracellular vesicles (EVs) have proven that EVs have a high …

Using Tangible Interaction And Virtual Reality To Support Spatial Perspective Taking Ability, Shen-Kuen Chang

Open Access Dissertations

According to several large-scale and longitudinal studies, spatial ability, one of the primary mental abilities, has been shown as a significant predictor for STEM learning (Science, Technology, Engineering, and Mathematics) and career success. Frameworks in HCI (Human-Computer Interaction) and TEI (Tangible and Embodied Interaction) also indicated how the spatial-related aspects of interaction are a common design theme for interfaces using emerging technologies. However, currently only very few interactive systems (using TEI) are designed around a target spatial ability. TEI’s direct effects on spatial ability are also not well-investigated. Meanwhile, a growing body of research from cognitive sciences, such as embodied …

Characterization Of Type I Collagen And Osteoblast Response To Mechanical Loading, Silvia P. Canelón

Open Access Dissertations

Bone is a composite material made up of an inorganic (hydroxyapatite mineral) phase, a proteinaceous organic phase, and water. Comprising 90% of bones organic phase, type I collagen is the most abundant protein in the human body. Both hydroxyapatite and collagen contribute to bone mechanical properties, and because bone is a hierarchical material, changes in properties of either phase can influence bulk mechanical properties of the tissue and bone structure. Type I collagen in bone is synthesized by osteoblasts as a helical structure formed from three polypeptide chains of amino acids. These molecules are staggered into an array and the …

Magnetic Resonance Imaging For The Functional Analysis Of Tissues And Biomaterials, Luyao Cai

Open Access Dissertations

Articular cartilage provides mechanical load dissipation and lubrication between joints, and additionally provides protects from abrasion. At present, there are no treatments to cure or attenuate the degradation of cartilage. Early detection and the ability to monitor the progression of osteoarthritis is important for developing effective therapies. However, few reliable imaging biomarkers exist to detect cartilage disease before advanced degeneration in the tissue. One specialized MRI technique, termed displacements under applied loading by MRI (dualMRI), was developed to measure displacements and strain in musculoskeletal tissues, hydrogels and engineered constructs. However, deformation information does not directly describe spatial distributions of tissue …

Regulation Of Intestinal Lipid Storage And Mobilization, Alicia L. Carreiro

Open Access Dissertations

Dietary fat is an energy dense nutrient that also provides essential fatty acids and aids in the absorption of fat soluble vitamins. The process of dietary fat absorption regulates the amount and rate at which dietary fat enters circulation, and can therefore contribute to diseases such as obesity, diabetes and cardiovascular disease when it becomes dysregulated. Triacylglycerol (TAG), the major form of dietary fat, is efficiently absorbed (>95%) even when high amounts of fat are consumed. The digestive products of dietary fat are taken up by enterocytes, the absorptive cells of the small intestine, and rapidly re-synthesized into TAG. …

Effect Of Cue Cardinality, Cue Representation And Judgment Options On Human Judgments, Harsh Wardhan Aggarwal

Open Access Dissertations

Judgment studies using different set of cues have been used from over 50 years to understand how people make judgments. Brunswik’s Lens Model, a regression model which combines the ecological and the human’s judgment model using a common set of cues, has been the primary tool of choice for these judgment studies. Yet, despite a common model, there is no consensus on how much information people need to make judgments, or how the information should be represented or even how the judgment options should be presented to people. Therefore, this study in the first phase, used a Monte Carlo simulation …

Experimentally Validated Quantum Transport Models For Tunneling Devices Based On Novel Materials, Tarek A. Ameen Beshari

Open Access Dissertations

The desire to reduce the power consumption of consumer electronics has driven the semiconductor industry to seek smaller transistors and to operate them at lower supply voltages. A reduction in the transistors dimensions by a certain fraction can reduce the power consumption by the same amount, for a specific operation speed. The semiconductor industry employs a 14nm feature size for its latest technology node and is pushing it down to 10nm. Moreover, reducing the supply voltage can also significantly lower the power consumption. However, the limit on the supply voltage is set by the threshold voltage, which is more than …

Design And 3d Printing Of Integrated Fluid Power Components, Alfonso Costas

Open Access Theses

In this work, the 3D printing of fluid power components was explored. There are many reasons why the use of additive manufacturing (AM) may be beneficial to this industry. Amongst these reasons, it is worth mentioning the freedom to develop new designs, as well as the weight and size reduction. In addition, thanks to 3D printing it is possible to integrate different fluid power components, otherwise seen as separate parts of an assembly, into one single part, avoiding the need for further assembly. In this work, the following components have been developed: a lobe pump, several soft actuators, a gate …

Validation Of Object Identification And Tracking In Radar Imagery, Daniel T. Dietz

Open Access Theses

Analysis of storm cells and tracking thereof in radar imagery requires substantial effort if done manually. An automated technique for performing cell identification and tracking can greatly ease the burden of performing the work by hand. For analyzing post-event cases automated techniques are a time-saver for the investigators and when analyzing real-time radar data or NWP output, applying automated techniques is necessary because the products must be made available in real-time to be useful. Evaluating the performance of such techniques is also a time consuming task because the comparative truth must be found by hand. A method of simulating storm …

Exploring Generation Z’S Work Values: Implications For Future Work, Pei-Yu Hsieh

Open Access Theses

Work values are often studied in literature with relation to generational issues as they represent an important norm in comparing and understanding expectations of various generations of employees in the workplace. Generation Z, individuals born between 1995 and 2010, is preparing to enter the workplace, yet there is limited exploring of the work values that motivate this generation. This study aims to explore the work values of Generation Z and provide insights to organizational managers and Human Resources (HR) as they cope with the challenges of a new generation in the workplace. This quantitative study consists of a research question …

Effects Of Starch-Entrapped Microsphere Supplementation On Metabolic Phenotype In C57bl/6j Mice, Sean Mcnabney

Open Access Theses

Resistant starches are complexes of amylose and/or amylopectin that are indigestible or only partially digestible in the small intestine. When these starches enter the colon, they undergo fermentation via resident bacterial strains to produce the short-chain fatty acids acetate, propionate, and butyrate. Not only does butyrate act as an energy source for colonocytes and regulate luminal pH, but butyrate supplementation has also been demonstrated to confer anti-inflammatory and chemopreventive benefits in cell culture models. Moreover, in murine models of diet-induced obesity and insulin resistance, dietary supplementation of sodium butyrate attenuated weight gain, reduced adipose tissue accumulation, and maintained insulin sensitivity …

Perceiving The Communication Methods Between Deaf Pilots And Air Traffic Control, Raymart F. Tinio

Open Access Theses

Many people are often inspired when finding out that I, a Deaf pilot, can fly. The general population assumes that pilots must be able to communicate via radio to fly, thus resulting in the belief that deaf people cannot be pilots. Yet, there are Deaf pilots in the United States and in other countries. As Deaf pilots, we use communication methods other than the radio to communicate with air traffic controllers. The most common communication method used by Deaf pilots may be the light gun signals, but it may not be enough to support Deaf pilots in a career as …

Manchurian Rootstocks Influence Eab Resistance When Grafted To North American Ash, Sara C. Stack

Open Access Theses

Emerald ash borer (EAB; Agrilus planipennis Fairmaire Coleoptera: Buprestidae) is an invasive phloem-boring pest from Asia that has killed tens of millions of North American ash trees (Fraxinus spp.). In its native range, EAB only attacks highly stressed ash trees, functioning as a secondary pest. Because Asian ash shares a co-evolutionary history with EAB, they possess a suite of secondary defensive compounds that prevent EAB from successfully colonizing healthy trees. However, all North American ash trees, regardless of health, are susceptible to EAB, and typically die within four years of infestation. Propagating ash resistant to EAB is crucial to maintaining …

Designing Academic Libraries In The Digital Age, Clarence Maybee, Nanette Andersson, Karen Hum

Libraries Faculty and Staff Presentations

Today’s academic libraries must accentuate the interdependent relationship of the libraries and academic units, creating innovations that advance teaching and learning on their campuses. In August 2017, the Libraries at Purdue University opened the Thomas S. and Harvey D. Wilmeth Active Learning Center (WALC), a 164,000-square-foot facility that houses the Library of Engineering and Science (LOES) and 27 classrooms designed for active learning. The WALC represents a new approach the design of academic libraries, allowing new opportunities to extend informal learning in library spaces placed next to innovative active learning classrooms. During the envisioning stage, Purdue Libraries worked with an …

Standards Are Everywhere: A Freely Available Introductory Online Educational Program On Standardization For Product Development, Margaret Phillips, Michael Fosmire, Paul B Mcpherson

Libraries Faculty and Staff Scholarship and Research

The collaboration between the Purdue Libraries and the Purdue Polytechnic Institute on standards education goes back to the 1980’s.[i] With a shared goal of preparing students for success after graduation, the Libraries and (then) Department of Mechanical Engineering Technology (MET) devised activities and instruction to show students that they will need to be able to find information ‘beyond the textbook’ to solve the problems they will face in the workplace. They will need specific information that relates to their particular circumstance, whether it is a material property, production technique, or an industry standard.

In recent years, the Libraries and Polytechnic …

Information Literacy In The Disciplinary Classroom: Three Views, Clarence Maybee, Michael Flierl

Librarians involved with IMPACT collaborate with instructors to redesign courses while also seeking opportunities to integrate information literacy (IL) into course curricula in ways that support disciplinary learning. The Libraries conducted three research studies exploring aspects related to teacher, student and librarian stakeholders of the IMPACT program. The research uses both quantitative and qualitative methods to examine: 1) teachers’ views of IL in active learning environments, 2) students’ motivation and performance related …

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Department of Psychological Sciences Faculty Publications

Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …

Notes From Johannesburg - Dialogues And Itineraries Of The South From Kinshasa: Art, History, And Education, David Andrew

Artl@s Bulletin

This text was originally a brief speech in a debate – Dialogues and Itineraries of the South from Kinshasa: Art, History and Education that took place at Mário de Andrade Library’s Auditorium in São Paulo (Brazil) on October 26^th 2016. It draws from questions and discussions in Kinshasa, concerning arts education, the challenges in decolonizing curriculum and methods, connecting them to South African experiences, particularly at the Wits School of Arts (Johannesburg) and also from the Another Road Map School research group workshops.

Think Natural ! Une Nécessité Qui Ne Se Cache Plus, Cedrick Nzolo Ngamobu

Artl@s Bulletin

This contribution raises questions regarding the search for mediation and transition found in pedagogy and the creative process. This can be posed as a response to an affirmation of identity, coupled with a search for philosophical autonomy. The need for mediation or transition is a necessity that we all seek in different ways and according to our respective contexts. In teaching in a school of art or fashion, it is a question with different variables that leaves the field open to all forms of questioning and brings to the fore the confrontation of modes of expression.

Œuvre D’Art Comme Récit Historique (Rapport Des Discussions Du Groupe De Travail), Emi Koide

Artl@s Bulletin

This report aims to present central questions raised during two days of group discussion and debate concerning the theme « art work as history ». Several different points of view were presented, in which generational frictions in kinois artistic milieu came to the fore. The main subjects during the discussions were: the challenges involved in writing Art History in the Congo through their own perspectives; the importance on creating archives about Congolese art locally; considering artwork as historical narrative; the importance of the body as a link between object and performance, as well as between material and immaterial dimension.

Cadrer Temps Et Histoire (Rapport Des Discussions Du Groupe De Travail), Matthias De Groof

Artl@s Bulletin

This group session discussed the notion of “Framing time and history” and investigated the ways in which the current practices of its participants (some of which emerged from the context of the Académie des Beaux-Arts de Kinshasa) are concrete examples of a South-South dialogue and how this can provide a critical perspective on art history and art education. Debates concerning the how and the why of that dialogue through art production, distribution and criticism are presented.

Au-Delà Des Rivalités Provinciales : Poétiques Visuelles Tropicalistes Et Autres Projets D’Art Étendu Depuis La Perspective Du Nord-Est Brésilien, Ayrson Heráclito

Artl@s Bulletin

This text is a compilation of writings published during the course of our research for the 3^rd Biennale of Bahia (2014), for which we worked in the curatorial team. These investigations reflect on the genealogy of Northeast Brazil’s contemporary art, seeing this region as unrestricted and non-essentialist. The production of certain artists is considered within an expanded context. To this end, we employed the idea of PEBA (Pernambuco-Bahia), while attempting to come to terms with the possibility of existence of a family, united by the desire for a poetic turn in the tropics.

Aesthetic Autopsy. Collective Memory And Trauma In Contemporary Art From Angola, Nadine Siegert

Artl@s Bulletin

Angolan history is mainly a history of wars. After the long anti-colonial fight (1961 – 1974) that ended with the independence of the country in 1975, a civil war between the former independence movements started. In the 1980s, Angola was the venue for a proxy war between the Socialist bloc and Western countries, supporting the different protagonists fighting on Angolan territory. After the crumbling of cold war ideologies in 1989, the war continued as a struggle for political hegemony and access to natural resources until 2002, devastating lands, economy and social structures. These historical events might have led to trauma …

This article considers the story of the late Laurent-Désiré Kabila, President of the Democratic Republic of Congo, as told by the popular painters of the city of Lubumbashi. Its shows how popular painting contributes to the knowledge of LD Kabila's reign, by serving as a support for oral history. Indeed, the commentaries of the paintings made by their authors or by critics unveil a chapter of history. Placed next to each other according to their theme and chronological order, popular paintings depict the highlights of the history of a given region in a specific area such as politics, economy, culture, …

Lumumba’S Iconography As Interstice Between Art And History, Matthias De Groof

Artl@s Bulletin

How does Congolese art and artistic representations of Lumumba “mediate past, present and future”? How do they relate to historical narratives and to the dialogues within the Global South? This contribution proposes Lumumba’s iconography as a case in point of the interstice between art and history. It positions the image of Lumumba as mediating between past, present and future for both the Congo and the Global South more broadly.

Retour À L’Authenticité In The City: A Photo Essay, Ruth Sacks Dr

Artl@s Bulletin

These photographs were taken as part of a larger research project tracing Mobutu Sese Seko’s construction projects in Kinshasa in the late 1960s and 1970s. The sites were part of a drive initially taking place under Mobutu’s cultural policy of retour à l’authenticité, instigated in 1967 as a means of taking recourse in pre-colonial Congolese traditions. This gave rise to a wide variety of architectural styles, adorned by artworks largely commissioned from a group called the avant-gardists. The selection of photos seen here presents glimpses of some of the sites and their artworks.

Le Paradigme « Art Africain » : De L’Origine À Sa Physionomie Actuelle, Henri Kalama

Artl@s Bulletin

This study relooks at the problematic concept of "African Art". The conceptual evolution of "African Art" coincides with three realities: firstly, that the art discovered in Africa was described as uncivilized; secondly, that this art capitulated with the colonial past of Africa; finally, that this art of an underdeveloped continent. In such a context of emergence, this art has been or is still exploited by ambitious and interested promoters. Hence, there is an imperative need for contemporary artists to overcome all these influences to produce works whose ontological values and universality cannot be challenged.

Les Nouveaux Défis Du Métier D’Artiste En République Démocratique Du Congo, André Yoka Lye

Artl@s Bulletin

The history of art institutions in D.R. Congo is relatively old compared to the rest of Africa. This justifies the know-how of Congolese artists since 1930-40’s, even if the general trend was, for a long time, reliant on amateurism and mimetism of European production. With the integration of art institutes into university education level since 1971, the issues and challenges became precise and appeared to be possible to overcome: professionalization, rooted and applied research, community building and international competitiveness, with the urge of solidarity with countries and experiences from the South.
