description: Extreme heat is increasingly plaguing urban environments, placing vulnerable urban populations at disproportionate risk of heat illness and energy burden. This study investigated differences in heat risk and discomfort due to extreme heat and cooling problems, and related consequences of power outages across four legacy cities: Cincinnati, Ohio, Cleveland, Ohio, Detroit, Michigan, and Milwaukee, Wisconsin. Our overarching research questions were: 1) How many people have access to air conditioning (AC)?; 2) How many people are experiencing heat burden (thermal discomfort)?; 3) To what degree is AC used as a coping mechanism?; 4) How is cooling ability impacted by grid failure?; and 5) What are reported health impacts due to loss of AC, such as visits to the ER? For each city, we examined Public Use File microdata available at the metropolitan statistical area (MSA) level from modules newly added to the 2023 American Housing Survey on heat risk, cooling problems, and power outages. We used contingency tables to correlate presence and functional status of AC with reported discomfort due to indoor heat or power outage, household behaviors of limiting use of AC due to cost, and visits to the emergency room due to indoor heat. The results showed that 87.87 to 96.5% of households had access to AC. Cleveland and Detroit had the highest proportion of residents lacking access, at 10.28% and 12.13% respectively. Between 6.24% and 8.26% of the MSAs experienced heat burden, with Cleveland (7.49%) and Detroit (8.26%) at the upper range. Coping-related results showed that access to AC did not guarantee protection from extreme indoor temperatures, energy costs did not greatly impact the use of AC, and effectiveness of AC was contingent on the home’s energy efficiency. 21.55% of Detroit households experienced power outages compared to 14.56% to 15.13% of residents in the other three MSAs. Power outages caused spoiled food, loss of refrigerated medicine, disruption to electric medical devices, displacement, and lost work. Cleveland reported the highest percentage of respondents requiring hospitalization due to heat (1.09%), followed by Cincinnati (0.98%), Milwaukee (0.94%), and Detroit (0.76%).
Essays on Achieving Success in Peer Production: Contributor Management, Best Practice Transfer and Inter- Community Relationships
Creators: name: Haiyi  Zhu
Publisher: name: Carnegie Mellon University

description: Since the late twentieth century, open source software projects (e.g., the GNU/Linux operating system, the Apache web server, Perl and many others) have achieved phenomenal success. This success can be attributed to a new paradigm of productivity in which individuals voluntarily collaborate to produce knowledge, goods and services. Benkler claims this productivity paradigm is a “new, third mode of production” particularly suited for “the digitally networked environment” (2002). In addition to its application to open source software projects, the peer production model, in different forms, has been used in areas such as science/citizen science (Silvertown, 2009), library science (Weinberger, 2007), politics (Castells, 2007; Jenkins, 2006), education (Daniel, 2012), journalism (Gillmor, 2004), and culture (Jenkins, 2006; Lessig, 2004). As peer production has flourished, merely describing successful cases has become less useful. Instead, scholars must identify the dynamics, structures, and conditions that contribute to or impede that success. In this dissertation, I focus on three management challenges at three distinct levels that impede the success of peer production. At the individual level, one significant question is how to best organize individual contributors with differing goals, experience, and commitment to achieve a collective outcome. At the practice level, peer production communities, like corporations, must often transfer best practices from one unit to another to improve performance. This transfer process poses the challenge of how to adapt and modify an original practice to make it effective in the new context. At the community level, peer production communities must learn to survive and succeed in a large ecosystem of related communities. This dissertation combines theoretical approaches in organization science with in-depth empirical analysis on a range of peer production communities to examine the mechanisms that help the communities overcome these three management challenges and succeed in peer production. The contributions of my dissertation are twofold. For scholars and researchers, my dissertation advances the theoretical understanding of the underlying mechanisms of successful peer production systems. For practitioners, my dissertation offers practical advice to build more effective peer production projects and platforms.

description: This study investigates the spin susceptibility in U-based superconductor UTe$_2$ in the superconducting (SC) state by using Knight shift measurements for a magnetic field $H$ along the $a$ axis, which is the magnetic easy axis of UTe$_2$. Although a tiny anomaly ascribed to the SC diamagnetic effect was observed just below the SC transition temperature $T_{\rm c}$, the $a$-axis Knight shift in the SC state shows no significant decrease, following the extrapolation from the normal-state temperature dependence. This indicates that the spin susceptibility is nearly unchanged below $T_{\rm c}$. Considering the previous Knight shift results for $H \parallel b$ and $H \parallel c$, the dominant SC state is determined to be $B_{\rm 3u}$ in the spin-triplet pairing, which is consistent with the spin anisotropy in the normal state. The present result shows that UTe$_2$ is a spin-triplet superconductor with spin degrees of freedom.

description: Complementarity - the absence of a phase boundary separating the Higgs and confinement phases of a gauge theory - can be violated by the addition of chiral fermions. We utilize chiral symmetry violating fermion correlators such as $ \langle \bps ψ\rangle $ as order parameters to investigate this issue. Using inequalities similar to those of Vafa-Witten and Weingarten, we show that SU(2) gauge theories with Higgs and fermion fields in the fundamental representation exhibit chiral symmetry breaking in the confined phase and therefore do {\it not} lead to massless composite fermions. We discuss the implications for the Abbott-Farhi strongly interacting standard model.

description: A recent experimental study (Phys. Rev. Appl. 9, 024023, 2018) on paramagnetic CeCo$_3$ finds that Magnesium alloying induces a ferromagnetic transition with intrinsic properties large enough for permanent magnet applications. Here we explain these surprising results \textit{via} a first principles study of the electronic structure and magnetism of Magnesium-alloyed CeCo$_3$. We find the origin of this Magnesium-induced ferromagnetic transition to be Stoner physics - the substantial increase in the Fermi-level density-of-states $N(E_F)$ with Mg alloying. Our calculations suggest that both Ce and Co atoms are important for generating large magnetic anisotropy suggesting the viability of Co-3$d$, and Ce-4$f$ interaction for the generation of magnetic anisotropy in magnetic materials. These results offer a new route to the discovery of ferromagnetic materials and provide fundamental insight into the magnetic properties of these alloys

description: The geometrical properties of the icosahedral ordered structure formed in liquid and glassy phases of metallic glasses are investigated by using molecular dynamics simulations. We investigate the Zr-Cu alloy system as well as a simple model for binary alloys, in which we can change the atomic size ratio between alloying components. In both cases, we found the same nature of icosahedral order in liquid and glassy phases. The icosahedral clusters are observed in liquid phases as well as in glassy phases. As the temperature approaches to the glass transition point Tg, the density of the clusters rapidly grows and the icosahedral clusters begin to connect to each other and form a medium-range network structure. By investigating the geometry of connection between clusters in the icosahedral network, we found that the dominant connecting pattern is the one sharing seven atoms which forms a pentagonal bicap with five-fold symmetry. From a geometrical point of view, we can understand the mechanism of the formation and growth of the icosahedral order by using the Regge calculus, which is originally employed to formulate a theory of gravity. The Regge calculus tells us that the distortion energy of the pentagonal bicap could be decreased by introducing an atomic size difference between alloying elements and that the icosahedral network would be stabilized by a considerably large atomic size difference.
Constraints on tidal charge of the supermassive black hole at the Galactic Center with trajectories of bright stars

description: As it was pointed out recently in Hees et al. (2017), observations of stars near the Galactic Center with current and future facilities provide an unique tool to test general relativity (GR) and alternative theories of gravity in a strong gravitational field regime. In particular, the authors showed that the Yukawa gravity could be constrained with Keck and TMT observations. Some time ago, Dadhich et al. (2001) showed that the Reissner -- Nordström metric with a tidal charge is naturally appeared in the framework of Randall -- Sundrum model with an extra dimension ($Q^2$ is called tidal charge and it could be negative in such an approach). Astrophysical consequences of of presence of black holes with a tidal charge are considerered, in particular, geodesics and shadows in Kerr -- Newman braneworld metric are analyzed in (Schee and Stuchlik, 2009a), while profiles of emission lines generated by rings orbiting braneworld Kerr black hole are considered in (Schee and Stuchlik, 2009b). Possible observational signatures of gravitational lensing in a presence of the Reissner -- Nordström black hole with a tidal charge at the Galactic Center are discussed in papers by Bin-Nun (2010a, 2010b, 2011). Here we are following such an approach and we obtain analytical expressions for orbital precession for Reissner -- Nordstrom -- de-Sitter solution in post-Newtonian approximation and discuss opportunities to constrain parameters of the metric from observations of bright stars with current and future astrometric observational facilities such as VLT, Keck, GRAVITY, E-ELT and TMT.

In partiacular, we consider the KdV and Boussinesq hierarchy to show that the Virasoro and W-constraints follow from the string equation by expanding the ``additional symmetry" operator in terms of the Lax operator. We also mention how this method could be generalized for higher KdV hierarchies.

description: We discuss two independent issues about the baryon asymmetry of the universe. First, assuming that it is generated by an unspecified source at high temperatures, we study the effects of non-perturbative $SU(2)_W$ dynamics above the electroweak scale, in the context of supersymmetric models. We find that there is a substantial difference with the nonsupersymmetric case with the net effect of relaxing previous bounds on B and L violating interactions. In particular supersymmetry allows neutrino masses as large as 10 eV (preferred by solar neutrino and COBE data and measurable at future neutrino oscillation experiments). Second, we argue that the existence of a mixed lepton number-gravitational anomaly in the standard model will induce B-L violating interactions. These transitions would be catalized by Einstein-Yang-Mills instantons or sphalerons and could create a primordial B-L asymmetry at Planck temperatures or lower. Gravity (and the anomaly structure of the standard model) could then be the ultimate source of the baryon asymmetry. We analyze the viability of the presently known gravitational instantons and sphalerons to realize this scenario. (Talk presented by FQ at the Texas/Pascos Conference, Berkeley Dec.1992.)

description: An overview on photon echo spectroscopy under resonant excitation of the exciton complexes in semiconductor nanostructures is presented. The use of four-wave-mixing technique with the pulsed excitation and heterodyne detection allowed us to measure the coherent response of the system with the picosecond time resolution. It is shown that, for resonant selective pulsed excitation of the localized exciton complexes, the coherent signal is represented by the photon echoes due to the inhomogeneous broadening of the optical transitions. In case of resonant excitation of the trions or donor-bound excitons, the Zeeman splitting of the resident electron ground state levels under the applied transverse magnetic field results in quantum beats of photon echo amplitude at the Larmor precession frequency. Application of magnetic field makes it possible to transfer coherently the optical excitation into the spin ensemble of the resident electrons and to observe a long-lived photon echo signal. The described technique can be used as a high-resolution spectroscopy of the energy splittings in the ground state of the system. Next, we consider the Rabi oscillations and their damping under excitation with intensive optical pulses for the excitons complexes with a different degree of localization. It is shown that damping of the echo signal with increase of the excitation pulse intensity is strongly manifested for excitons, while on trions and donor-bound excitons this effect is substantially weaker.
Precision of Hubble constant derived using black hole binary absolute distances and statistical redshift information

description: Measured gravitational waveforms from black hole binary inspiral events directly determine absolute luminosity distances. To use these data for cosmology, it is necessary to independently obtain redshifts for the events, which may be difficult for those without electromagnetic counterparts. Here it is demonstrated that certainly in principle, and possibly in practice, clustering of galaxies allows extraction of the redshift information from a sample statistically for the purpose of estimating mean cosmological parameters, without identification of host galaxies for individual events. We extract mock galaxy samples from the 6th Data Release of the Sloan Digital Sky Survey resembling those that would be associated with inspiral events of stellar mass black holes falling into massive black holes at redshift z ~ 0.1 to 0.5. A simple statistical procedure is described to estimate a likelihood function for the Hubble constant H_0: each galaxy in a LISA error volume contributes linearly to the log likelihood for the source redshift, and the log likelihood for each source contributes linearly to that of H_0. This procedure is shown to provide an accurate and unbiased estimator of H_0. It is estimated that a precision better than one percent in H_0 may be possible if the rate of such events is sufficiently high, on the order of 20 to z = 0.5.

description: Several studies have documented the persistence of economic development outcomes across space and over a long period. Other studies have argued that the reversal of fortune has also taken place over time and space. Since different areas of current Nigeria were once under the rule of states with different degrees of political centralization and later investment in Koranic, this study seeks to explore whether areas or districts under a more centralized political system are more likely to participate in large-scale school expansion programmes such as the 1976 Universal Primary Education (UPE) and 1999 Universal Basic Education (UBE). To check for evidence of reversal of fortune, we determine whether the degree of state centralization on school participation is more or less in areas that have large investments in Koranic education. OLS results show that while an index of state centralization has a positive and significant impact on enrolment in UPE and UBE programmes, the effect is negative and statistically significant for those with heavy investment in Koranic education (measured by district fraction of 1914-46 cohorts with Koranic education). The results are robust to adding an extensive range of explanatory variables and other range of specification tests. While the structure of the economy at the onset of Islamic activities in Nigeria may have made investment in Koranic education worthwhile, nevertheless the contemporary world does not require Koranic education to make either regional or national advancement possible. Thus, there is a clear case of mismatch between the demands of modern economic life and the skills possessed by a large section of it. Thus, well-thought-out policies are required to address this mismatch and accelerate inclusive economic development.
Search for high-mass resonances in final states with a lepton and missing transverse momentum at $\sqrt{s}=$ 13 TeV

description: A search for new high-mass resonances in proton-proton collisions having final states with an electron or muon and missing transverse momentum is presented. The analysis uses proton-proton collision data collected in 2016 with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The transverse mass distribution of the charged lepton-neutrino system is used as the discriminating variable. No significant deviation from the standard model prediction is found. The best limit, from the combination of electron and muon channels, is 5.2 TeV at 95% confidence level for the mass of a W$'$ boson with the same couplings as those of the standard model W boson. Exclusion limits of 2.9 TeV are set on the inverse radius of the extra dimension in the framework of split universal extra dimensions. In addition, model-independent limits are set on the production cross section and coupling strength of W$'$ bosons decaying into this final state. An interpretation is also made in the context of an R parity violating supersymmetric model with a slepton as a mediator and flavor violating decay.

description: Data management can be a frustrating process. Typically this involves using spreadsheets, writing adhoc Python scripts, or using R, Catmandu or similar tools. Albeit these tools have their own strengths, they also have various problems when used in managing repository content. Spreadsheets can be very labour intensive and clumsy for example for data with multiple authors. Using scripts requires coding good skills and often adhoc scripts are not documented and therefore not very useful for other team members. GLAMpipe is an open source, flexible-by-design, document processing tool meant for GLAM (Galleries, Libaries, Archives, Museums) data. GLAMpipe can be used for data importing, exporting, processing and browsing. It has a graphical user interface and a full REST api. The workflow of GLAMpipe is based on nodes. There are import nodes, processing nodes, export nodes and view nodes. Import nodes can import data from REST apis (like Dspace 6 or Wikidata) or CSVfiles.Processing files can make lookups, transfomations, metadata mappings, string operations and so on. Export nodes can push data and files to different REST apis (like Dspace 6) or CSV file. The workshop is intended to everyone who is doing data management or who is creating a tools for content management.

subject: FOS: Economics and business

description: This dissertation seeks to examine three well-known problems in three different areas of financial economics: The effects of regulation on the financial sector; the provision of incentives to limit freeriding in teams; and the lack of empirical support for the consumption-based asset pricing model. In the first essay, I address the current debate on the costs and benefits of financial regulation, and I show that financial regulation can increase bank shareholder value by reducing shareholder monitoring costs. I use a regression discontinuity design to study the effect of an unexpected decrease in small-bank reporting requirements to the Federal Reserve. Using the reporting change as a negative shock to regulatory monitoring by the Fed, I find that reduced Fed monitoring leads to a 1% loss in Tobin’s q and a 7% loss in equity market-to-book. I show that these losses come from increased internal monitoring expenditures, managerial rents, and monitoring conflicts between shareholders. My results are among the first to quantify the shareholder value of monitoring. In the second essay (with Benjamin Tengelsen and Ariel Zetlin-Jones), we re-examine the importance of separation between ownership and labor in team production models that feature free riding. In such models, conventional wisdom suggests an outsider is needed to administer incentive schemes that do not balance the budget. We analyze the ability of insiders to administer such incentive schemes in a repeated team production model with free riding when they lack commitment. Specifically, we augment a standard, repeated team production model by endowing insiders with the ability to impose group punishments which occur after team outcomes are observed but before the subsequent round of production. We extend techniques from Abreu (1986) to characterize the entire set of perfect-public equilibrium payoffs and find that insiders are capable of enforcing welfare enhancing group punishments when they are sufficiently patient. In the third essay, I re-examine an important prediction of asset pricing theory which has historically found little support in the data—that expected consumption growth and equity returns should be correlated. I first show empirically that advertising growth is a good proxy for expected consumption growth, as it predicts both consumption growth and equity returns in aggregate post-war US data. To shed light on the link between advertising growth, expected consumption, and expected returns, I then build and calibrate a dynamic model of goods market frictions where firms invest in advertising to build their customer capital (as in Gourio and Rudanko (2014)). Within the model, I show that the severity of goods market frictions is a key element to replicate the predictability patterns I observe in the data.

description: We study the higher spin anologs of the six vertex model on the basis of its symmetry under the quantum affine algebra $U_q(\slth)$. Using the method developed recently for the XXZ spin chain, we formulate the space of states, transfer matrix, vacuum, creation/annihilation operators of particles, and local operators, purely in the language of representation theory. We find that, regardless of the level of the representation involved, the particles have spin $1/2$, and that the $n$-particle space has an RSOS-type structure rather than a simple tensor product of the $1$-particle space. This agrees with the picture proposed earlier by Reshetikhin.

description: Search engines are widely used by researchers to locate research materials on the internet, they provide optimization techniques to content developers to allow their content show up among the top lists while a user types in their topic of interest. Repositories that have not been optimized will not show up among the top lists or never at all making its content to have low visibility and therefore low citations. Researchers then see no benefits of submitting their content on these platforms. I propose that all open repositories be search engine optimized because this will lead to the content of their researchers more visible to other researchers. Visibility will allow for more citations and hence a motivating factor for researchers to submit more content to the institutional open repository. I also demonstrate the impact of this on Uganda Christian University open Repository where I started off without optimization and later optimized. The number of researchers willing to give us their work has increased greatly due to the benefit of visibility of their research online. I believe that the greatest motivator of researchers is having their work more visible to the public other than monitory benefits.

description: We investigate the statistical properties of isotropic, stochastic, Gaussian distributed, helical magnetic fields characterized by different shapes of the energy spectra at large length scales and study the associated realizability condition. We discuss smoothed magnetic fields that are commonly used when the primordial magnetic field is constrained by observational data. We are particularly interested in scale-invariant magnetic fields that can be generated during the inflationary stage by quantum fluctuations. We determine the correlation length of such magnetic fields and relate it to the infrared cutoff of perturbations produced during inflation. We show that this scale determines the observational signatures of the inflationary magnetic fields on the cosmic microwave background. At smaller scales, the scale-invariant spectrum changes with time. It becomes a steeper weak-turbulence spectrum at progressively larger scales. We show numerically that the critical length scale where this happens is the turbulent-diffusive scale, which increases with the square root of time.

A potential problem of the negative mass squared for the SUSY standard model (SSM) sfermions in the D-term gauge mediation is solved by the contribution from the U(1)' mediation. On the other hand, the splitting between the SSM gauginos and sfermions in the U(1)' mediation is circumvented by the contributions from the D-term gauge mediation. Since the U(1)' mediation does not introduce any new SUSY vacua, we achieve a completely stable model under thermal effects. Our model, therefore, has no cosmological difficulty.

description: This ongoing work aims to provide citation information for users of DSpace repositories. Its scope is on Lume's journal article community - which has knowledge areas as collections - and its citations within this community. This community may point the citation increasing of articles published in scientific journals and available in institutional open access repositories. The Extract Transform Load (ETL) approach consists of three steps: (1) - Data collection; (2) – Citations discovery; and (3) - Load processed data. From the process, for example, one can explore a specific period, areas of knowledge, and groups of authors. It can provide relevant information to users about a particular type of document or author; as well as how, when and where the citation occurred in documents. The disclosure of these results aims the encouragement of the deposit of works in open access IR and its usage.
Creeping motion of a solid particle inside a spherical elastic cavity

description: On the basis of the linear hydrodynamic equations, we present an analytical theory for the low-Reynolds-number motion of a solid particle moving inside a larger spherical elastic cavity which can be seen as a model system for a fluid vesicle. In the particular situation where the particle is concentric with the cavity, we use the stream function technique to find exact analytical solutions of the fluid motion equations on both sides of the elastic cavity. In this particular situation, we find that the solution of the hydrodynamic equations is solely determined by membrane shear properties and that bending does not play a role. For an arbitrary position of the solid particle within the spherical cavity, we employ the image solution technique to compute the axisymmetric flow field induced by a point force (Stokeslet). We then obtain analytical expressions of the leading order mobility function describing the fluid-mediated hydrodynamic interactions between the particle and confining elastic cavity. In the quasi-steady limit of vanishing frequency, we find that the particle self-mobility function is higher than that predicted inside a rigid no-slip cavity. Considering the cavity motion, we find that the pair-mobility function is determined only by membrane shear properties. Our analytical predictions are supplemented and validated by fully-resolved boundary integral simulations where a very good agreement is obtained over the whole range of applied forcing frequencies.

Spherical collapse and cluster number counts in dark energy models disformally coupled to dark matter

description: We investigate the effects of a disformal coupling between dark energy and dark matter in the predictions of the spherical collapse and its signatures in galaxy cluster number counts. We find that the disformal coupling has no significant effects on spherical collapse at high redshifts, and in particular during matter domination epoch. However, at lower redshifts, the extrapolated linear density contrast at collapse close to redshift $z \lesssim 1$ and overdensity at virialization can be strongly suppressed by a disformal coupling between dark energy and dark matter. We also find that disformal coupling can have different imprints on cluster number counts compared with conformal coupling, such that the disformal coupling can strongly suppress the predicted number of clusters per redshift interval at $z > 0.1$ while enhance the number of cluster at $z < 0.05$. Using the specifications of eROSITA survey, we find that the disformal coupling between dark energy and dark matter can be tightly constrained by cluster number counts.

From Coxeter Higher-Spin Theories to Strings and Tensor Models

description: A new class of higher-spin gauge theories associated with various Coxeter groups is proposed. The emphasize is on the $B_p$--models. The cases of $B_1$ and its infinite graded-symmetric product $sym\,(\times B_1)^\infty$ correspond to the usual higher-spin theory and its multi-particle extension, respectively. The multi-particle $B_2$--higher-spin theory is conjectured to be associated with String Theory. $B_p$--higher-spin models with $p>2$ are anticipated to be dual to the rank-$p$ boundary tensor sigma-models. $B_p$ higher-spin models with $p\geq 2$ possess two coupling constants responsible for higher-spin interactions in $AdS$ background and stringy/tensor effects, respectively. The brane-like idempotent extension of the Coxeter higher-spin theory is proposed allowing to unify in the same model the fields supported by space-times of different dimensions. Consistency of the holographic interpretation of the boundary matrix-like model in the $B_2$-higher-spin model is shown to demand $N\geq 4$ SUSY, suggesting duality with the $N=4$ SYM upon spontaneous breaking of higher-spin symmetries. The proposed models are shown to admit unitary truncations.

description: In the first chapter, I build a New Keynesian asset pricing model with optimal monetary policy and Epstein-Zin preferences that accounts for some of the stylized facts concerning the term structures of equity and bond risk premia. The model-implied term structure of equity risk premia and its volatility are downward sloping, the term structure of bond risk premia is upward sloping, and the term structure of Sharpe ratios on dividend strips is downward sloping.
