Social Capital And The Martial Law Technocracy: The Making And Unmaking Of A Power Elite, Teresa S. Encarnacion Tadem Phd

Kritika Kultura

This paper attempts to show the extent to which a faction of the Philippine technocracy during the martial law years utilized its social capital (used interchangeably with cultural capital) to become a potent economic bloc in society only to see it gradually depleted.Led by then Prime Minister and concurrent Finance Minister Cesar E.A. Virata, this bloc consisted of key senior economic officials who were closely associated with IMF-World Bank policies. Their social capital was founded on their family and educational backgrounds, paving the way for their acquisition of the technical expertise required by the business community and later, by government. …

Technology Development Of High-Resolution Single-Cell Lineage Tracing For Cell Reprogramming Systems, Sadie Vanhorn

Arts & Sciences Electronic Theses and Dissertations

A critical element of cell identity is the cell that created the observed cell. This parent cell dictates many aspects of its identity, whether measured by function, phenotype, or specific assays. The cell’s lineage impacts the ability of the cell to differentiate into final cell types in development or successfully reprogram in direct cell reprogramming. Here, we evolve molecular barcoding techniques to increase the resolution of lineage recording at single-cell resolution. Using single-cell RNA-sequencing as the readout for this measurement, polyadenylated reporter gene transcripts with engineered 3’ untranslated regions were designed to initially label and then record lineage information. While …

Capacity-Weighted Figures-Of-Merit For Battery Transport Metrics, Cj Sturgill, Christopher Sutton, Julian Schwenzel, Morgan Stefik

Faculty Publications

New battery materials with improved transport are needed. Typical measurements yield widely varying voltage-dependent diffusivities and reporting practices are diverse. Some materials (e.g. first-order phase change) have most redox occur at a specific voltage and may be sufficiently represented by singular transport metrics. Many rapid intercalation materials, however, exhibit second-order phase transitions with redox over a broad voltage range. How should such cases be compared? The use of capacity-weighted average values is suggested where voltage-dependent metrics are consolidated into representative descriptors as figures-of-merit. Examples are elaborated where differential capacity (dQ/dV) is used to derive a …

Community, State And Professionalism: Negotiating The Experience Of Community Health Workers In The Provision Of Maternal And Child Health Services In Tanzania, Chakupewa Joseph Mpambije

Journal of Humanities and Social Sciences

Research on community health workers (CHWs) has been on the increase in the past decades in Tanzania, focusing on the provision of maternal and child health (MCH) services. While performing their tasks, CHWs work within three constructs: the community, the state, and their professionalism. However, as CHWs work within these constructs, there exists scanty literature which discourses their experiences within the realm of the community, the state and their professionalism. This review aimed to articulate how these constructs facilitate or inhibit CHWs’ performance in improving MCH services. It employed a scoping review method in which peer-reviewed articles and grey literature …

Does Market Accessibility Improve Household Food Security? Evidence From Small-Holder Maize Producers In Southern Tanzania, Monica Sebastian Kauky

Journal of Humanities and Social Sciences

This study investigated the impact of market accessibility on household food security among smallholder maize producers in Southern Tanzania, utilizing data from a sample of 407 households primarily engaged in maize farming. Tobit and probit models assessed the relationship between food security and market access. Contrary to expectations, the findings revealed no significant association between market access and food security. Instead, the results underscored the importance of resource availability, indicating that larger farm sizes and higher household wealth indices significantly reduce the risk of food insecurity. These findings suggest that rather than focusing exclusively on enhancing market access, policymakers should …

Terrestrial Evidence For Volcanogenic Sulfate-Driven Cooling Event ~30 Ka Before The Cretaceous–Paleogene Mass Extinction: Volcanism-Induced Cooling ~30 Ka Pre-K–Pg Boundary, Lauren O'Connor, Rhodri Jerrett, Gregory Price, Tyler Lyson, Sabine Lengger, Francien Peterse, Bart Van Dongen

School of Geography, Earth and Environmental Sciences

Alongside the Chicxulub meteorite impact, Deccan volcanism is considered a primary trigger for the Cretaceous–Paleogene (K–Pg) mass extinction. Models suggest that volcanic outgassing of carbon and sulfur—potent environmental stressors—drove global temperature change, but the relative timing, duration, and magnitude of such change remains uncertain. Here, we use the organic paleothermometer MBT′5me and the carbon-isotope composition of two K–Pg-spanning lignites from the western Unites States, to test models of volcanogenic air temperature change in the ~100 kyr before the mass extinction. Our records show long-term warming of ~3°C, probably driven by Deccan CO2 emissions, and reveal a transient (<10 kyr) ~5°C cooling event, coinciding with the peak of the Poladpur “pulse” of Deccan eruption ~30 kyr before the K–Pg boundary. This cooling was likely caused by the aerosolization of volcanogenic sulfur. Temperatures returned to pre-event values before the mass extinction, suggesting that, from the terrestrial perspective, volcanogenic climate change was not the primary cause of K–Pg extinction.

Aspiration Of Left Atrial Masses Using The Large-Bore Manual Aspiration System: The Aspirate La Procedure, Shaurya Srivastava, Hussam Al Hennawi, Ahmad Abulshamat, Appa Bandi, Mohammed Qintar

Abington Jefferson Health Papers

Transcatheter mass extraction of left-sided cardiac masses has gained popularity in recent years, with scarce data on effectiveness, safety, and types of devices used. Mostly, left-sided aspirations use mechanical and continuous-flow–mediated devices (the AngioVac [AngioDynamics] and Penumbra systems [Penumbra]). To our knowledge, the use of manual aspiration devices has not been reported yet. Here, we report the first case series on the use of the AlphaVac (AngioDynamics) (a large-bore manual aspiration device) system for left-sided intracardiac masses.

Multi-Omic Analysis Of Phototrophic Extracellular Electron Uptake In Novel Rhodovulum Spp. Isolated From A Marine Estuary, Emily J. Davenport

Arts & Sciences Graduate Student Theses and Dissertations

Microbial metabolisms are incredibly versatile and dynamic, allowing adaptive strategies for growth in even the most limiting environments. For an ever-increasing number of microbes, this includes utilizing soluble or insoluble inorganic mineral species as electron donors, driving geochemical cycles and microbial metabolisms. This metabolic function of transporting electrons derived from the extracellular environment across cell membranes is called extracellular electron uptake (EEU). Within (photo)autotrophs, (p)EEU also sustains CO2 fixation to cell biomass, implicating a potentially fundamental role of microbial carbon cycling in aquatic and soil ecosystems. A model metabolic scheme of pEEU occurring in natural environments is photoferrotrophy, which pairs …

Synthesis Of Higher-Order Catenanes And Catenane-Based Materials, Gray Harlan

Arts & Sciences Graduate Student Theses and Dissertations

Catenanes are a subset of mechanically interlocked molecules (MIMs) and are composed of interlocked rings that can be oriented linearly, radially, or branched. A defining feature of all MIMs is that they are bound through their architectures consisting of mechanical bonds, leading to unique topologies. Catenanes have attracted interest due to their stimuli-responsive behavior and the degrees of freedom afforded by the mechanical bond, a feature which is absent with standard covalent bonds. The stimuli responsiveness of catenanes arises from their templated syntheses, where two or more pre-macrocycles are brought together by a driving force. Various templation strategies rely on …

Pyrophosphate-Free Glycolysis In Clostridium Thermocellum Increases Both Thermodynamic Driving Force And Ethanol Titers, Bishal Dev Sharma, Shuen Hon, Eashant Thusoo, David M. Stevenson, Daniel Amador-Noguez, Adam M. Guss, Lee R. Lynd, Daniel G. Olson

Dartmouth Scholarship

Background

Clostridium thermocellum is a promising candidate for production of cellulosic biofuels, however, its final product titer is too low for commercial application, and this may be due to thermodynamic limitations in glycolysis. Previous studies in this organism have revealed a metabolic bottleneck at the phosphofructokinase (PFK) reaction in glycolysis. In the wild-type organism, this reaction uses pyrophosphate (PPi) as an energy cofactor, which is thermodynamically less favorable compared to reactions that use ATP as a cofactor. Previously we showed that replacing the PPi-linked PFK reaction with an ATP-linked reaction increased the thermodynamic driving force of glycolysis, but only had …

Multi-Antigen Elephant Endotheliotropic Herpesvirus (Eehv) Mrna Vaccine Induces Humoral And Cell-Mediated Responses In Mice, Jessica R Watts, Jennifer L Spencer Clinton, Jeroen Pollet, Rongsheng Peng, Jie Tan, Paul D Ling

Faculty, Staff and Students Publications

Background/Objectives: Elephant endotheliotropic herpesvirus (EEHV) causes lethal hemorrhagic disease (HD) in Asian and African elephants in human care and the wild. It is the leading cause of death for young Asian elephants in North American and European zoos despite sensitive diagnostic tests and improved treatments. Thus, there is a critical need to develop an effective vaccine to prevent severe illness and reduce mortality from EEHV-HD. We generated a multi-antigenic EEHV mRNA vaccine to address this need that encodes the EEHV1A-subtype glycoproteins gB, gH, gL, and gO. These conserved proteins are the entry machinery for several herpesviruses in the betaherpesvirus subfamily …

Targeting Corticotropin-Releasing Hormone Receptor Type 1 (Crhr1) Neurons: Validating The Specificity Of A Novel Transgenic Crhr1-Flpo Mouse, Mason Hardy, Yuncai Chen, Tallie Z Baram, Nicholas J Justice

Faculty, Staff and Student Publications

Corticotropin-releasing hormone (CRH) signaling through its cognate receptors, CRHR1 and CRHR2, contributes to diverse stress-related functions in the mammalian brain. Whereas CRHR2 is predominantly expressed in choroid plexus and blood vessels, CRHR1 is abundantly expressed in neurons in discrete brain regions, including the neocortex, hippocampus and nucleus accumbens. Activation of CRHR1 influences motivated behaviors, emotional states, and learning and memory. However, it is unknown whether alterations in CRHR1 signaling contribute to aberrant motivated behaviors observed, for example, in stressful contexts. These questions require tools to manipulate CRHR1 selectively. Here we describe and validate a novel Crhr1-FlpO mouse. Using bacterial artificial …

A Topological Route To Engineering Robust And Bright Supersymmetric Laser Arrays, Soujanya Datta, Mohammad Alizadeh Fard, Ramy El-Ganainy, Krishanu Roychowdhury

Michigan Tech Publications

In recent years, several proposals that leverage principles from condensed matter and high-energy physics for engineering laser arrays have been put forward. The most important among these concepts are topology, which enables the construction of robust zero-mode laser devices, and supersymmetry (SUSY), which holds the potential for achieving phase locking in laser arrays. In this work, we show that the relation between supersymmetric coupled bosonic and fermionic oscillators on one side, and bipartite networks (and hence chiral symmetry) on another side can be exploited together with non-Hermitian engineering for building one- and two-dimensional laser arrays with in-phase synchronization. To demonstrate …

The performance of SDM has been compared with that of the Proportional Integral (PI) and Fuzzy Logic based controllers. Also, the thesis addresses the cybersecurity issues in solar PV based microgrids. The Ensemble Learning technique and an Improved Ensemble …

Schedulability Analysis Of Multi-Phase Limited-Preemption Tasks, Benjamin Standaert

McKelvey School of Engineering Graduate Student Theses & Dissertations

This work addresses hard real-time systems, in which tasks must be scheduled so that they are guaranteed to meet deadlines. In particular, when tasks execute across multiple domains with high preemption costs, the combined cost of these preemptions can cause the system to become unschedulable. The number of preemptions must therefore be bounded to limit the overall task execution time, while ensuring that task blocking times are small enough to allow the system to be schedulable. Prior work introduces the Multi-Phase Secure model, which describes a more exact version of this scenario, and an algorithm to determine schedulability of sporadic …

Codifying Domesticity: The Story Of The Recommended Minimum Requirements For Small Dwelling Construction Of 1923, The Housing Policy Of The Hoover Secretariat, And The Impact On American Residential Architecture, Noah Morris

Graduate School of Architecture & Urban Design Theses & Dissertations

During the nineteenth and twentieth centuries, fire disasters and health-safety issues led to the widespread adoption of building codes. While the National Board of Fire Underwriters published the National Building Code in 1905, the code did not maintain regulatory consistency across the nation. This lack of consistency across the nation and socio-economic factors contributed to a nation-wide housing shortage of a million units by 1919. During World War I, the government addressed the housing crisis through the United States Housing Corporation and Emergency Fleet Corporation, building public housing based on the ideals of the Garden City Movement.[1] Following the …
