description: When I say “I know Sarah,” or “I know Berlin,” what sort of knowledge am I claiming? Such knowledge of a particular is, I claim, not reducible to either propositional knowledge-that or to traditional physical know-how. Mere, bare knowledge by acquaintance also does not capture the kind of knowledge being claimed here. Using knowledge of a place as my central example, I argue that this kind of knowledge-of, or “objectual knowledge” as it is sometimes called, is of a distinctive epistemological sort. It is a genre of inherently first-personal aesthetic knowledge, but it also, like know-how, involves active skill. I end by exploring a couple of classic problems in aesthetic epistemology, applied to the case of knowledge-of as active aesthetic knowledge. © 2022 The Authors.

description: Polariton condensates are investigated in periodical potentials created by surface acoustic waves using both resonant and non-resonant optical excitation. Under resonant pumping condensates are formed due to polariton parametric scattering from the pump. In this case the single particle dispersion in the presence of the condensate shows a strong reduction of the energy gap arising from the acoustic modulation, indicating efficient screening of the surface acoustic wave potential by spatial modulation of the polariton density. The observed results are in good agreement with a model based on generalised Gross-Pitaveskii equations with account taken of the spatial dependence of the exciton energy landscape. In the case of incoherent, non-resonant pumping coexisting non-equilibrium condensates with s- and p- type wavefunctions are observed, which have different energies, symmetry and spatial coherence. The energy splitting between these condensate states is also reduced with respect to the gap of the one particle spectrum below threshold, but the screening effect is less pronounced than in the case of resonantly pumped system due to weaker modulation of the pump state.

description: Radiogenic strontium isotopes (87Sr/86Sr) of vein carbonates play a central role in the tectonometamorphic study of fold-and-thrust belts and accretionary wedges and have been used to document fluid sources and fluxes, for example, along major fault zones. In addition, the 87Sr/86Sr ratios of vein carbonates can trace the diagenetic to metamorphic evolution of pore fluids in accreted sediments. Here we present 87Sr/86Sr ratios of vein carbonates from the Infrahelvetic flysch units of the central European Alps (Glarus Alps, Switzerland), which were accreted to the North Alpine fold-and-thrust belt during the early stages of continental collision. We show that the vein carbonates trace the Sr isotopic evolution of pore fluids from an initial seawater-like signature towards the Sr isotopic composition of the host rock with increasing metamorphic grade. This relationship reflects the progressive equilibration of the pore fluid with the host rock and allows us to constrain the diagenetic to low-grade metamorphic conditions of deformation events, including bedding-parallel shearing, imbricate thrusting, folding, cleavage development, tectonic mélange formation and extension. The strontium isotope systematics of vein carbonates provides new insights into the prograde to early retrograde tectonic evolution of the Alpine fold-and-thrust belt and helps to understand the relative timing of deformation events. © The Author(s), 2022.

description: We present the redshift lower limit of z>0.6035 for the very-high-energy (VHE; E>100 GeV) emitting blazar PKS 1424+240 (PG 1424+240). This limit is inferred from Lyman beta and gamma absorption observed in the far-ultraviolet spectra from the Hubble Space Telescope/Cosmic Origins Spectrograph. No VHE-detected blazar has shown solid spectroscopic evidence of being more distant. At this distance, VHE observations by VERITAS are shown to sample historically large gamma-ray opacity values at 500 GeV, extending beyond tau=4 for low-level models of the extragalactic background light (EBL) and beyond tau=5 for high-levels. The majority of the z=0.6035 absorption-corrected VHE spectrum appears to exhibit a lower flux than an extrapolation of the contemporaneous LAT power-law fit beyond 100 GeV. However, the highest energy VERITAS point is the only point showing agreement with this extrapolation, possibly implying the overestimation of the gamma-ray opacity or the onset of an unexpected VHE spectral feature. A curved log parabola is favored when fitting the full range of gamma-ray data (0.5 to 500 GeV). While fitting the absorption-corrected VHE data alone results in a harder differential power law than that from the full range, the indices derived using three EBL models are consistent with the physically motivated limit set by Fermi acceleration processes.

description: How do American universities navigate the tension between national security and academic freedom that arises during periods of great power competition? To answer this question, I examine two time periods when intense rivalry between the US and its rival country drove the American government to scrutinize universities: from 1947 to 1957, which encapsulates the Second Red Scare, and from 2013 to present day, which covers US-China great power competition. Across these two case studies, I find reoccurring patterns in the threat perceptions and mitigating strategies of the US government, university administrators, and professors. US government officials express concerns that foreign rivals are taking advantage of the openness of American universities to steal research and to brainwash students. These threat perceptions have led the government to investigate faculty accused of ties to foreign rivals, create new laws and policies, and publicly communicate to university administrators to try and mitigate these concerns. Much of these government strategies achieve success by pressuring administrators into complying with the government’s goals or by deterring faculty from carrying out certain actions. Some university administrators and faculty, meanwhile, argue that the government’s increased involvement threatens the core values of their institutions, especially academic freedom. A few have publicly expressed these concerns in attempts to pressure the government to limit its policies. Many university administrators, however, choose to cooperate with the government to protect their funding or because they agree with the government’s perspective. To protect themselves, many faculty members also limit their behavior and censor their studies. These trends indicate that balancing national security and academic freedom represents a difficult issue, one for which the US government, university administrators, and faculty have failed to reach a satisfactory solution. Modern developments in dual use technology and globalization only exacerbate this tension. This thesis hopes to inspire greater communication between policymakers, university administrators, and university faculty so all sides understand one another’s concerns.

description: Broadband terahertz spectroscopy enables many promising applications in science and industry alike. However, the complexity of existing terahertz systems has as yet prevented the breakthrough of this technology. In particular, established terahertz time-domain spectroscopy (TDS) schemes rely on complex femtosecond lasers and optical delay lines. Here, we present a method for optoelectronic, frequency-modulated continuous-wave (FMCW) terahertz sensing, which is a powerful tool for broadband spectroscopy and industrial non-destructive testing. In our method, a frequency-swept optical beat signal generates the terahertz field, which is then coherently detected by photomixing, employing a time-delayed copy of the same beat signal. Consequently, the receiver current is inherently phase-modulated without additional modulator. Owing to this technique, our broadband terahertz spectrometer performs (200 Hz measurement rate, or 4 THz bandwidth and 117 dB peak dynamic range with averaging) comparably to state-of-the-art terahertz-TDS systems, yet with significantly reduced complexity. Thickness measurements of multilayer dielectric samples with layer-thicknesses down to 23 µm show its potential for real-world applications. Within only 0.2 s measurement time, an uncertainty of less than 2 % is achieved, the highest accuracy reported with continuous-wave terahertz spectroscopy. Hence, the optoelectronic FMCW approach paves the way towards broadband and compact terahertz spectrometers that combine fiber optics and photonic integration technologies.

description: For the first time in over 50 years, the importance of peace and stability across the Taiwan Strait was raised in the 2021 Japan-U.S. Joint Leaders’ Statement. Not only did Tokyo’s increasingly assertive posture on the Taiwan issue attract domestic and international attention, but it was also interpreted as Tokyo shifting its policies on Taiwan. Tokyo’s perceived policy shifts could incur potential retaliation from Beijing and result in unfavorable outcomes due to Tokyo’s enormous economic, geographic, and political interests in China. Therefore, it is important to understand the intentions behind the perceived shifts. This thesis assesses the recent turns in Tokyo’s stances on Taiwan by reviewing the significant events among Japan, China, and Taiwan and analyzing the Diet debates on the Taiwan issue. This analysis of Tokyo’s stances on Taiwan since 1972 reveals no change in Tokyo’s fundamental policies; Tokyo continues to adhere to “One China” and maintains only unofficial ties with Taipei. However, the analysis does reveal shifts in attitudes toward Taiwan. Today’s assertive posture is rooted in Tokyo’s attitude shift after the Taiwan Strait crisis in 1995-1996, when Tokyo began linking its own national security with peace and stability in the Taiwan Strait. Tokyo’s increasing assertiveness is proportional to China’s increasing pressure on Taiwan. Tokyo’s posture reflects its goal to defend its national security by promoting peace and stability in the Taiwan Strait without purposefully opposing Beijing. This thesis predicts Tokyo will continue to increase its voice on the Taiwan issue as long as tension exists across the Strait but will not change its fundamental policies.
All CAT(0) Boundaries of Croke-Kleiner-Admissible Groups are Equivariantly CE Equivalent]

description: Question 2.6 of Bestvina's Questions in Geometric Group Theory asks whether every pair of boundaries of a given CAT(0) group G is cell-like equivalent. The question was posed by Bestvina shortly after the discovery, by Croke and Kleiner, of a CAT(0) group that admits multiple boundaries. Previously, it had been observed by Bestvina and Geoghegan that all boundaries of a torsion free CAT(0) G would necessarily have the same shape. Since "cell-like equivalence" is weaker than topological equivalence, but in most circumstances, stronger (and more intuitive) than shape equivalence, this question is a natural one when working with the pathological types of spaces that occur as group boundaries. Furthermore, the definition of cell-like equivalence allows for a obvious G-equivariant extension. In this paper we provide a positive answer to Bestvina's G-equivariant Cell-like Equivalence Question for the class of admissible groups studied by Croke and Kleiner in 2002. Since that collection includes the original Croke-Kleiner group, our result provides a strong solution to Q2.6, for the group that originally motivated the question.

description: The matrix sign function is shown to provide a simple and direct method to derive some fundamental results in the theory of surface waves in anisotropic materials. It is used to establish a shortcut to the basic formulas of the Barnett-Lothe integral formalism and to obtain an explicit solution of the algebraic matrix Riccati equation for the surface impedance. The matrix sign function allows the Barnett-Lothe formalism to be readily generalized for the problem of finding the surface wave speed in a periodically inhomogeneous half-space with material properties that are independent of depth. No partial wave solutions need to be found; the surface wave dispersion equation is formulated instead in terms of blocks of the matrix sign function of i times the Stroh matrix.

description: For a believer in locality of Nature, the Aharonov-Bohm effect and the Aharonov-Casher effect are paradoxes. I discuss these and other Aharonov's paradoxes and propose a local explanation of these effects. If the solenoid in the Aharonov-Bohm effect is treated quantum mechanically, the effect can be explained via local interaction between the field of the electron and the solenoid. I argue that the core of the Aharonov-Bohm and the Aharonov-Casher effects is that of quantum entanglement: the quantum wave function describes all systems together.

description: Entrepreneurial ecosystems (EEs) are currently a major theme of entrepreneurship research and policies designed to support entrepreneurship. However, the role of specific policy instruments in EEs often remains unclear. This paper contributes to research on that topic by analysing the role of start-up competitions (SUCs) in the contrasting German case study regions Berlin and Hanover. Based on 45 qualitative interviews with participants in two public SUCs, their organizers, and ecosystem experts, the role that the SUCs play in each EE is investigated. Both analysed SUCs serve as networking events that can be described as ‘anchor events’ for specific parts of their ecosystems. They provide strong support for participants and help local entrepreneurship support offices connect and allocate their resources efficiently. However, sub-networks of entrepreneurs and actors who are not connected to the SUCs are identified. The SUCs seem to work primarily for public actors, ‘solid’ entrepreneurs, and university spin-offs. International venture capitalists, wealthy business angels, and high growth firms are not involved in the competitions. Both analysed regions influence the perceived value of their competitions, e.g. in terms of the industrial expertise of jurors. © 2022 The Author(s).

A New Rhetorical Legacy? Humanitarianism, Human Rights, and US Foreign Military Intervention (1980-2020)

Publisher: name: Stanford Digital Repository

description: Previous academic literature indicates that the United States has used the rhetoric of democracy, international norms, and national security to justify its foreign military interventions from the Cold War to the War on Terror (Kerton-Johnson, 2011). However, scholars have failed to substantially investigate the American use of human rights rhetoric as a defense of military intervention. When the United States has intervened militarily in a foreign country, how has it used human rights rhetoric to justify its military action? Which human rights does the U.S. cite, and how do these statements match the reality of the human rights conditions on the ground for each case? To answer these questions, I conducted original textual analysis of 60 presidential speeches from the American Presidency Project and compared human rights justifications from these speeches to the actual human rights situations of each case. Through my research, I critically analyze the existence and political implications of the invocation of human rights rhetoric in the past, present, and future of American foreign policy. This thesis finds that American presidents historically have used human rights rhetoric to justify U.S. foreign military intervention, particularly during responses to humanitarian crises in the 1990s and more recently since the 2011 intervention in Libya. Further, within these justifications, presidents most often invoke the rhetoric of personal integrity rights, such as the human right to "life, liberty, and security." However, presidential uses of human rights rhetoric do not match human rights situations on the ground. American presidents frequently portray U.S. foreign policy as addressing human rights violations, yet there is no statistically significant relationship between presidential uses of human rights rhetoric and the actual human rights situations within countries of intervention. This thesis contributes new scholarship to the understanding of U.S. foreign policy and how it is argued to domestic and foreign publics. Through its multilevel investigation, this thesis raises critical implications of presidents’ potential to abuse the use of humanitarian and human rights rhetoric in justifications for U.S. military intervention.

description: We provide a comparative study of basic electrical properties of bulk single crystals of transparent semiconducting oxides (TSOs) obtained directly from the melt (9 compounds) and from the gas phase (1 compound), including binary (β-Ga2O3, In2O3, ZnO, SnO2), ternary (ZnSnO3, BaSnO3, MgGa2O4, ZnGa2O4), and quaternary (Zn1−xMgxGa2O4, InGaZnO4) systems. Experimental outcome, covering over 200 samples measured at room temperature, revealed n-type conductivity of all TSOs with free electron concentrations (ne) between 5 × 1015 and 5 × 1020 cm−3 and Hall electron mobilities (μH) up to 240 cm2 V−1 s−1. The widest range of ne values was achieved for β-Ga2O3 and In2O3. The most electrically conducting bulk crystals are InGaZnO4 and ZnSnO3 with ne > 1020 cm−3 and μH > 100 cm2 V−1 s−1. The highest μH values > 200 cm2 V−1 s−1 were measured for SnO2, followed by BaSnO3 and In2O3 single crystals. In2O3, ZnO, ZnSnO3, and InGaZnO4 crystals were always conducting, while others could be turned into electrical insulators.

description: Photographs are considered to be the most powerful and trustworthy media of expression. For a long time, those were accepted as proves of evidences in varied fields such as journalism, forensic investigations, military intelligence, scientific research and publications, crime detection and legal proceedings, investigation of insurance claims, medical imaging etc. Today, digital images have completely replaced the conventional photographs from every sphere of life but unfortunately, they seldom enjoy the credibility of their conventional counterparts, thanks to the rapid advancements in the field of digital image processing. The increasing availability of low cost and sometimes free of cost image editing software such as Photoshop, Corel Paint Shop, Photoscape, PhotoPlus, GIMP and Pixelmator have made the tampering of digital images even more easier and a common practice. Now it has become quite impossible to say whether a photograph is a genuine camera output or a manipulated version of it just by looking at it. As a result, photographs have almost lost their reliability and place as proves of evidences in all fields. This is why digital image tamper detection has emerged as an important research area to establish the authenticity of digital photographs by separating the tampered lots from the original ones. This paper gives a brief history of image tampering and a state-of-the-art review of the tamper detection techniques.

description: Since the 1800s, levees, embankments that prevent water from entering a floodplain, have played a critical role in U.S. flood management. 
While physics-based models are used by engineers prior to construction projects to limit adverse impacts, flood victims, law suits, and academic papers have asserted that in redistributing floodwater, levees redistribute flood risk up or downstream—to communities without this infrastructure. However, there has been little empirical research examining the actual effect of levees on stage (surface water level). We examine this question at a national scale, extending the simple statistical method of a small-scale study (in IL, IA) to levees in the National Levee Database, then generalize this approach to a fully Bayesian treatment using a multi-level model. 
While the original small-scale study found that levee construction significantly increased stage upstream and adjacent to levees, we find that this result does not generalize nationally. However, the mutli-level model offers many advantages over the previous methods in this application, and allows us to study effect heterogeneity, where preliminary results suggest that non-accredited levees and those in regions with high silt soil composition may be more likely to exhibit stage increases.

description: Universities can contribute to knowledge-based regional development not only in their home region but also in other regions. In a number of countries, universities have established university satellite institutes in additional (host) regions to promote research and technology transfer there. We investigate the role of university satellite institutes in the industrial development of regions, which, albeit not economically marginal, suffer from a weak knowledge infrastructure, limited absorptive capacities for external knowledge in the business sector and hence a low degree of attractiveness for non-local knowledge actors. Despite policy recommendations in favor of establishing satellite institutes, there has only been limited empirical research on this phenomenon, particularly concerning technology transfer ecosystem development. To fill this gap, we provide an exploratory case study of university satellite institutes in the Pearl River Delta of China’s Guangdong province. We show how such institutes can be successful in facilitating the development of their host region’s technology transfer ecosystems and demonstrate why they should be conceptually included in our existing understanding of third mission activities. Our research centers on the interplay of geographical proximity and non-spatial, organized proximity in the development of interregional knowledge bridges and entrepreneurial opportunities. We argue that the university’s geographical proximity is only successful if the satellite institute, by facilitating organized proximity, promotes the geographical proximity of further knowledge actors, hereby propelling ecosystem development. © 2021, The Author(s).

description: This thesis, submitted in partial fulfillment of the requirements for the degree of Masters of Arts, East Asian Studies,  examines the painting practice of contemporary multi-media artist, Zheng Chongbin (b. 1961). This study focuses on four other theoretical perspectives that Zheng has variously adapted, reconfigured, retranslated or reoriented to better suit the materiality of his chosen media, the processes of his artistic production, and the expressive, perceptual and intellectual directions of his interests. These include treatises by historical Chinese artists and critics, Shitao and Xie He; the spatial phenomenology incorporated in the architectural paintings of the seventeenth-century Dutch painter, Pieter Saenredam (1597-1665), and the combination of fractal pattern theory with ecological and New Materialism understandings.

description: The mechanisms underlying damage in high-performance polymer nanocomposites are remarkably affected by hygrothermal conditions. In this study, we develop a phase-field formulation to investigate the influence of hygrothermal conditions on the nonlinear viscoelastic fracture behavior of epoxy resins and their nanocomposites at finite deformation. For this, the Helmholtz free energy, capturing the effect of temperature and moisture and nanoparticle contents, is defined based on an additive decomposition of the energy into an equilibrium, a non-equilibrium, and a volumetric contribution with different definitions under tensile and compressive loading. The coupled displacement phase-field problem is solved using a quasi-Newton monolithic algorithm and a staggered solution scheme. Numerical examples show that the monolithic algorithm is more efficient. Simulations are performed to investigate the effect of temperature, deformation rate, and moisture content on the force–displacement response of boehmite nanoparticle/epoxy samples in benchmark numerical problems. Comparing numerical predictions and experimental data for compact-tension tests shows good agreement at different nanoparticle contents. Also, the model’s capability to predict fracture patterns is evaluated using simulations of single-edge notched nanocomposite plates under tensile and shear loading. © 2022, The Author(s).

description: The COVID-19 pandemic has exacerbated societal and health inequities globally. In rural China, in particular, disparities in caregiver and child health already existed and may have shifted, in part due to the uniquely strict lockdown mandates. Caregiver outcomes, caregiving behaviors, and perinatal health services utilization seemingly changed immediately for the many under-resourced communities in rural China. By studying the outcomes and behaviors of families with children born before lockdowns and those with children born during lockdowns, I identify the profound impacts of the COVID-19 pandemic on communities in rural China. I find that paternal but not maternal migration significantly slowed during the pandemic and related lockdowns, which may have contributed to the significantly improved mental health outcomes in caregivers – most often mothers and grandmothers in rural China – through heightened social support. Caregiving behaviors of household and nutrition expenditures and infant feeding practices generally remained the same, other than a significant increase in spending on infant micronutrient supplements. Perinatal health services utilization suffered significantly in some areas, particularly in postnatal care, yet significantly improved in other areas, such as in aspects of prenatal care. This research has implications in public health initiatives and global health policies to improve quality of life for the most vulnerable populations. Contributing knowledge through academic research to the literature on caregiver and child health is essential to promoting equity and transforming lives.
Challenging the State: Western European Regionalism in the Era of Financial Crisis

description: The Global Financial Crisis and its aftershocks have substantially altered the Western European political landscape. But while the literature has extensively focused on the impacts of the economic hardship on traditional party competition, it has often failed to consider the center-periphery dimension. This thesis addresses both the demand for and supply of regionalist ideologies during the crisis. Using an original dataset containing 8 countries, 35 regions, and 128 regionalist parties, it finds that voters did not increase their support for regionalist parties during the crisis and may have even turned their backs on these political actors. In addition, I consider the reactions of regionalist parties in three Spanish autonomous communities, Catalonia, the Basque Country, and Galicia, to the crisis. I find evidence of regionalist mobilization on the issue and even some indications of radicalization of regionalist demands. Taken together, these findings raise interesting implications for the impacts of the financial crisis and the interaction between economic indicators, party competition, and voting patterns.

Corporate responsibility and place leadership in rural digitalization: the case of Hidden Champions

description: We examine the role of Hidden Champions in rural areas in advancing regional digitalization through corporate local and regional responsibility and place leadership. Endowed with abundant internal resources and high innovative capacity, these global niche market leaders face regional resource constraints, concerning digital infrastructure and workforce with digital capabilities. 57 semi-structured interviews with firm representatives and regional actors in rural Germany are analyzed. We show that these enterprises strategically use measures of corporate local and regional responsibility and exert place leadership to develop digitalization-related assets in their rural regions. These initiatives are operated through modes of both inclusive and exclusive agency and benefit. We find that the motives for these actions are grounded in a perceived lack of swiftness and capacity of public actors, but also entail emotional attachment to the region, particularly for family businesses. Our findings have implications for regional policymakers, such as targeting greater alignment of regional and corporate development goals. © 2022 The Author(s).

The Effect of California's Local Control Funding Formula on School-Level Resources for English Language Learners

description: Since the 1990s, state school finance reforms have progressively allocated funds to disadvantaged students with the goal of narrowing academic achievement gaps. In 2013, California Governor Jerry Brown signed into law the Local Control Funding Formula (LCFF) to target supplemental and concentration funds to districts with larger shares of low-income students, foster youth, and English Language Learners (ELL). Studies have shown that LCFF has increased total school resources in high-need districts, as the policy intended. However, LCFF does not guarantee additional district funds are spent on school-level resources for target students, such as ELLs. To investigate the effect of LCFF on ELLs’ access to resources, this paper analyzes the pre- and post-LCFF trends in the between-district, within-district, and statewide resource disparities for ELLs relative to their non-ELL peers. My primary focus is the within-district resource disparity, as less is known about LCFF’s impact on resources for ELLs among schools within the same district. Consistent with previous research, I find that between-district resource disparities for ELLs increased in progressivity post LCFF. In contribution to the literature, I find that the within-district resource allocation for ELLs maintained similar levels of progressivity. I find no evidence that LCFF worsened resource allocation patterns at any organizational level for ELLs.

description: In this contribution we describe a novel solution for the construction of Positron Emission Tomograph. We present the device allowing for determination of the impact position as well as time and deph of interaction of the annihilation gamma quanta. The device is comprised of scintillation chamber consisting of organic scintillators surrounding the body of the patient. We discuss two possible solutions: (i) the tomograph built out of scintillator strips, and (ii) the tomograph built out of the scintillator plates. The application of the fast scintillators will enable to take advantage of the difference between time of the registration of the annihilation quanta. The invented method will permit to use a thick layers of detector material with the possibility of measuring the depth of the gamma quantum interaction (DOI) and the determination of their time of flight (TOF), and will allow for increasing the size of the diagnostic chamber without a significant increase of costs. The method is a subject of two patent applications which are based on the techniques used in the particle physics experiments.
