Chinese Domestic Workers as Inferior ‘Other’: Why Are They Particularly Vulnerable Yet Neglected?

Dual labour market

description: There are currently millions of domestic workers as vulnerable and underclass workers in China. The demand for domestic workers will continue to increase in another millions of urban families in time of ageing and labour shortage. Domestic workers are predominantly working poor female, low-skilled migrant and informal: these three characteristics have determined their poor conditions in the cities. When such a large body of domestic workers live in the improvised, disadvantaged and discriminated conditions in urban China, it is crucial to undertake a critical analysis of this issue to explore why this has happened and why it has been so hard to change their conditions. This thesis seeks to explain: why is there a persistent lack of social and legal protection for these vulnerable workers in urban China? To do so, I first explore two lines of theoretical frameworks to construct the issues of domestic workers in 1) the gender implications of domestic work and 2) the relationship between migration and labour market mechanism. Second, I analyse the larger socioeconomic structures that shape the working and living conditions of domestic workers. The process of reconstructing the dual labour system integrated with the institutionalized urban registration system in China has exacerbated the divergence between countryside and cities, between men and women, and between formal and informal labour. Third, I use the case studies to present the consequences of the informality of domestic work service in China, including the unrecognition of labour law, the unequal power relationship between service employers and domestic workers, and the media’s biased position in promoting the in-home care model. I find that the state has designed multiple institutions to secure a pool of cheap labour from the rural regions to facilitate the urbanisation at a low price. In particular, the central government has prioritised the urban development by encouraging more women to participate in the labour force and justified its absence in the provision of public elderly care by outsourcing the care services to the private market of domestic workers.
The dust grain size - stellar luminosity trend in debris discs

description: The cross section of material in debris discs is thought to be dominated by the smallest grains that can still stay in bound orbits despite the repelling action of stellar radiation pressure. Thus the minimum (and typical) grain size $s_\text{min}$ is expected to be close to the radiation pressure blowout size $s_\text{blow}$. Yet a recent analysis of a sample of Herschel-resolved debris discs showed the ratio $s_\text{min}/s_\text{blow}$ to systematically decrease with the stellar luminosity from about ten for solar-type stars to nearly unity in the discs around the most luminous A-type stars. Here we explore this trend in more detail, checking how significant it is and seeking to find possible explanations. We show that the trend is robust to variation of the composition and porosity of dust particles. For any assumed grain properties and stellar parameters, we suggest a recipe of how to estimate the "true" radius of a spatially unresolved debris disc, based solely on its spectral energy distribution. The results of our collisional simulations are qualitatively consistent with the trend, although additional effects may also be at work. In particular, the lack of grains with small $s_\text{min}/s_\text{blow}$ for lower luminosity stars might be caused by the grain surface energy constraint that should limit the size of the smallest collisional fragments. Also, a better agreement between the data and the collisional simulations is achieved when assuming debris discs of more luminous stars to have higher dynamical excitation than those of less luminous primaries. This would imply that protoplanetary discs of more massive young stars are more efficient in forming big planetesimals or planets that act as stirrers in the debris discs at the subsequent evolutionary stage.

The effects of controlling for distributional differences on the Mantel-Haenszel procedure
Creators: name: Bowen, Daniel F.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Propensity score matching was used to control for the distributional differences in ability between two simulated data sets. One data set represented English speaking examinees and the second data set represented Spanish speaking examinees who received the Spanish language version of the same test. The ability distributions of the two populations were set to mirror the data from a large-scale statewide assessment delivered in both English and Spanish. The simulated data were used as a benchmark to compare the Mantel-Haenszel procedure for identifying differential item function (DIF) under the two scenarios with the hope that controlling for distributional differences would reduce the errors made by the Mantel-Haenszel procedure in identifying DIF. With the increase in high-stakes testing of diverse populations in the United States as well as elsewhere in the world, it is critical that effective methods of identifying DIF be developed for situations where the reference and focal groups display distributional differences. However, the evidence of this study suggests that the matched samples did not help the Mantel-Haenszel procedure identify DIF, and in fact increased its errors.

description: Radio interferometers suffer from the problem of missing information in their data, due to the gaps between the antennas. This results in artifacts, such as bright rings around sources, in the images obtained. Multiple deconvolution algorithms have been proposed to solve this problem and produce cleaner radio images. However, these algorithms are unable to correctly estimate uncertainties in derived scientific parameters or to always include the effects of instrumental errors. We propose an alternative technique called Bayesian Inference for Radio Observations (BIRO) which uses a Bayesian statistical framework to determine the scientific parameters and instrumental errors simultaneously directly from the raw data, without making an image. We use a simple simulation of Westerbork Synthesis Radio Telescope data including pointing errors and beam parameters as instrumental effects, to demonstrate the use of BIRO.

Requirements for efficient cell-type proportioning: regulatory timescales, stochasticity and lateral inhibition

Year: 2015
Subjects: subject: Cell Behavior (q-bio.CB)

description: The proper functioning of multicellular organisms requires the robust establishment of precise proportions between distinct cell-types. This developmental differentiation process typically involves intracellular regulatory and stochastic mechanisms to generate cell-fate diversity as well as intercellular mechanisms to coordinate cell-fate decisions at tissue level. We thus surmise that key insights about the developmental regulation of cell-type proportion can be captured by the modeling study of clustering dynamics in population of inhibitory-coupled noisy bistable systems. This general class of dynamical system is shown to exhibit a very stable two-cluster state, but also frustrated relaxation, collective oscillations or steady-state hopping which prevents from timely and reliably reaching a robust and well-proportioned clustered state. To circumvent these obstacles or to avoid fine-tuning, we highlight a general strategy based on dual-time positive feedback loops, such as mediated through transcriptional versus epigenetic mechanisms, which improves proportion regulation by coordinating early and flexible lineage priming with late and firm commitment. This result sheds new light on the respective and cooperative roles of multiple regulatory feedback, stochasticity and lateral inhibition in developmental dynamics.
An Analysis of European Shale Gas Policies: Why EU Member States are Pursuing Divergent 'Fracking' Strategies
Creators: name: Thorne, Ben
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: The recent progression in hydraulic fracturing or `fracking' has enabled energy companies to extract once-considered, inaccessible hydrocarbons. The United States has been at the forefront of this controversial industry, revolutionizing the energy market by becoming the world's largest oil and natural gas producer as a result of its vast shale deposits. Shale oil and gas deposits are not unique to North America, however. EU member states are faced with the dilemma of whether to permit fracking domestically or suspend operations. The United Kingdom and Romania have issued concessions for exploring their reserves, while France and Bulgaria have halted all drilling efforts, citing environmental concerns. This paper evaluates why these four European countries pursued divergent fracking policies, arguing that energy security and Russian-relations are more relevant and powerful explanatory factors than a country's commitment to protecting the environment.
Scalar dark matter in the B-L model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The B-L extension of the Standard Model requires the existence of right-handed neutrinos and naturally realizes the seesaw mechanism of neutrino mass generation. We study the possibility of explaining the dark matter in this model with an additional scalar field that is a singlet of the Standard Model but charged under $U(1)_{B-L}$. An advantage of this scenario is that the stability of the dark matter can be guaranteed by appropriately choosing its B-L charge, without the need of an extra ad hoc discrete symmetry. We investigate in detail the dark matter phenomenology of this model. We show that the observed dark matter density can be obtained via gauge or scalar interactions, and that semi-annihilations could play an important role in the latter case. The regions consistent with the dark matter density are determined in each instance and the prospects for detection in future experiments are analyzed. If dark matter annihilations are controlled by the B-L gauge interaction, the mass of the dark matter particle should lie below 5 TeV and its direct detection cross section can be easily probed by XENON1T; if instead they are controlled by scalar interactions, the dark matter mass can be much larger and the detection prospects are less certain. Finally, we show that this scenario can be readily extended to accommodate multiple dark matter particles.

From Refugees to Model Minorities: Cuban-Americans and the Media in Miami, 1960-1970
Creators: name: Navarrete, Jeanine
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This thesis analyzes the emergence of competing ideological narratives about the Cuban community in Miami in the period from 1960 to 1970 in two major sources of print media, the Miami News and the Miami Herald, and nationally circulated periodicals ranging from the Saturday Evening Post to U.S. News & World Report. National periodicals reflected the public relations campaign undertaken by the Cuban Refugee Program and USIA, and printed celebratory stories about the economic and social assimilation of Cuban Americans that cast them as a model minority and counterpoint to the perceived breakdown of American values and the excesses of the Cold War establishment that culminated in the late 1960s. Conversely, in the Miami press, the growing Cuban exile community caused frequent panic about the city's cyclically depressed economy, the labor unrest that exacerbated racial tensions, and the challenge posed to Anglo cultural and racial hegemony by non-English speakers.

description: The Regge-Wheeler-Zerilli (RWZ) wave-equation describes Schwarzschild-Droste black hole perturbations. The source term contains a Dirac distribution and its derivative. We have previously designed a method of integration in time domain. It consists of a finite difference scheme where analytic expressions, dealing with the wave-function discontinuity through the jump conditions, replace the direct integration of the source and the potential. Herein, we successfully apply the same method to the geodesic generic orbits of EMRI (Extreme Mass Ratio Inspiral) sources, at second order. An EMRI is a Compact Star (CS) captured by a Super Massive Black Hole (SMBH). These are considered the best probes for testing gravitation in strong regime. The gravitational wave-forms, the radiated energy and angular momentum at infinity are computed and extensively compared with other methods, for different orbits (circular, elliptic, parabolic, including zoom-whirl).

description: MoS2 nanoparticles are proven catalysts for processes such as hydrodesulphurization and hydrogen evolution, but unravelling their atomic-scale structure under catalytic working conditions has remained significantly challenging. Ambient pressure X-ray Photoelectron Spectroscopy (AP-XPS) allows us to follow in-situ the formation of the catalytically relevant MoS2 edge sites in their active state. The XPS fingerprint is described by independent contributions to the Mo3d core level spectrum whose relative intensity is sensitive to the thermodynamic conditions. Density Functional Theory (DFT) is used to model the triangular MoS2 particles on Au(111) and identify the particular sulphidation state of the edge sites. A consistent picture emerges in which the core level shifts for the edge Mo atoms evolve counter-intuitively towards higher binding energies when the active edges are reduced. The shift is explained by a surprising alteration in the metallic character of the edge sites, which is a distinct spectroscopic signature of the MoS2 edges under working conditions.

description: We propose a new score-based algorithm for learning the structure of a Bayesian Network (BN). It is the first algorithm that simultaneously supports the requirements of (i) learning a BN of bounded treewidth, (ii) satisfying expert constraints, including positive and negative ancestry properties between nodes, and (iii) scaling up to BNs with several thousand nodes. The algorithm operates in two phases. In Phase 1, we utilize a modified version of an existing BN structure learning algorithm, modified to generate an initial Directed Acyclic Graph (DAG) that supports a portion of the given constraints. In Phase 2, we follow the BN-SLIM framework, introduced by Peruvemba Ramaswamy and Szeider (AAAI 2021). We improve the initial DAG by repeatedly running a MaxSAT solver on selected local parts. The MaxSAT encoding entails local versions of the expert constraints as hard constraints. We evaluate a prototype implementation of our algorithm on several standard benchmark sets. The encouraging results demonstrate the power and flexibility of the BN-SLIM framework. It boosts the score while increasing the number of satisfied expert constraints.

description: Background: Previous research showed that behavioural activation is as effective as cognitive-behavioural therapy for general depression. However, it remains unclear if it leads to greater improvement in depressive symptoms when compared with standard treatment for post-stroke depression. Aims: To compare the effectiveness of behavioural activation against control conditions in reducing depression symptoms in individuals with post-stroke depression. Method: This review searched five databases from inception until 13 July 2021 (updated 15 September 2023) for randomised controlled trials comparing behavioural activation and any control conditions for post-stroke depression. Risk of bias was assessed with the Cochrane Collaboration's Risk-of-Bias 2 tool. The primary outcome was improvement in depressive symptoms in individuals with post-stroke depression. We calculated a random-effects, inverse variance weighting meta-analysis. Results: Of 922 initial studies, five randomised controlled trials with 425 participants met the inclusion criteria. Meta-analysis showed that behavioural activation was associated with reduced depressive symptoms in individuals with post-stroke depression at 6-month follow-up (Hedges' g -0.39; 95% CI -0.64 to -0.14). The risk of bias was low for two (40%) of five trials, and the remaining three (60%) trials were rated as having a high risk of bias. Heterogeneity was low, with no indication of inconsistency. Conclusions: Evidence from this review was too little to confirm the effectiveness of behavioural activation as a useful treatment for post-stroke depression when compared with control conditions. Further high-quality studies are needed to conclusively establish the efficacy of behavioural activation as a treatment option for post-stroke depression.

Building Our Cultural Defenses: The Noninterventionist Rhetoric of the National Federation of Music Clubs
Creators: name: Conkle, Christian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The public writings of the National Federation of Music Clubs and its fourteenth president, Julia Ober, argued for American noninterventionism in the late 1930s and early 1940s. These texts deployed a conceptual and aesthetic framework for musical advocacy and activism in America, in which America's love for and preservation of traditional European classical music became a model for American peace during time of war. They proposed that European music could undergo a process of naturalization analogous to the naturalization of thousands of European émigrés. American musicians and audiences could perform, listen to, and love music originating from Axis countries without thereby supporting the Axis. Cultivating this music would create a safe harbor for the preservation of European culture throughout the war. Musical noninterventionism also promoted national defense through culture: focusing on art and music would help Americans resist foreign warmongering and at the same time create the foundations for a lasting American peace. This political program developed in contrast both to internationalist modernism and isolationist American nationalism, and also in opposition to contemporary masculine discourses of composition, aesthetics, and performance.

description: The increasing misalignment between the technological and economic domains in today’s digitalized global economy puts managers under constant pressure to redesign firms’ business models. Business model innovation has thus become a critical managerial challenge to develop and sustain competitive advantages. Building on the dynamic managerial capabilities perspective, we argue that managers are at the heart of strategic change through business model innovation. We hypothesize that decision-making regarding business model innovation is the outcome of how managers cognitively process information. We further reason that while managerial human capital and social capital reinforce each other, they also promote managers’ ability to consciously evaluate options for business model innovation. Our empirical study builds on a sample of firms operating primarily within the Industry 4.0 sector. The results significantly confirm managerial human and social capital as two crucial antecedents to cognitive business model innovation. Contrary to the literature, the data set does not show a significant positive relationship between managerial human and social capital. Our main contributions to the literature are twofold; from a methodological perspective, we are one of the first to construct a multidimensional measurement of dynamic managerial capabilities, while from a theoretical and practical perspective, our findings further underline the relevance of dynamic managerial capabilities for business model innovation. Finally, we discuss theoretical and practical implications and propose future avenues for research.
Short-lived lattice quasiparticles for strongly interacting fluids

description: It is shown that lattice kinetic theory based on short-lived quasiparticles proves very effective in simulating the complex dynamics of strongly interacting fluids (SIF). In particular, it is pointed out that the shear viscosity of lattice fluids is the sum of two contributions, one due to the usual interactions between particles (collision viscosity) and the other due to the interaction with the discrete lattice (propagation viscosity). Since the latter is {\it negative}, the sum may turn out to be orders of magnitude smaller than each of the two contributions separately, thus providing a mechanism to access SIF regimes at ordinary values of the collisional viscosity. This concept, as applied to quantum superfluids in one-dimensional optical lattices, is shown to reproduce shear viscosities consistent with the AdS-CFT holographic bound on the viscosity/entropy ratio. This shows that lattice kinetic theory continues to hold for strongly coupled hydrodynamic regimes where continuum kinetic theory may no longer be applicable.

Image Compression

description: We propose a learned method for stereo image compression that leverages the similarity of the left and right images in a stereo pair due to overlapping fields of view. The left image is compressed by a learned compression method based on an autoencoder with a hyperprior entropy model. The right image uses this information from the previously encoded left image in both the encoding and decoding stages. In particular, for the right image, we encode only the residual of its latent representation to the optimally shifted latent of the left image. On top of that, we also employ a stereo attention module to connect left and right images during decoding. The performance of the proposed method is evaluated on two benchmark stereo image datasets (Cityscapes and InStereo2K) and outperforms previous stereo image compression methods while being significantly smaller in model size.

Heroism In Elizabeth Catlett’s The Negro Woman, 1945-1946
Creators: name: Riegel, Julie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Elizabeth Catlett (April 15, 1915 -April 2, 2012) created The Negro Woman with a unique artistic approach that reflected her circulation among multiple artist groups, including the Popular Front in the United States, the New Negro Movement, and regionalism. Most notably, she borrowed the visual language and medium of the Taller de Grafica Popular (TGP), an artist collective based in Mexico, where she travelled to complete the Negro Woman Series in 1946. The TGP created art “for the people,” and its members held Marxist sympathies. The fifteen linocuts in The Negro Woman, which work together to describe the spectrum of experiences of African American women, show the complexities of the black female hero. Catlett wanted African American women to be able to see themselves through her art, since a majority of art that Catlett encountered in museums in the United States overwhelmingly marginalized or occluded black women. By creating images of heroic black females in the visual language popularized by the TGP, Catlett fuses the struggles and accomplishments of African American female protagonists with Marxist political sympathies. Catlett utilized the titles of her prints in The Negro Woman to develop the narrative through a singular African American female narrator. The titles and the images work together create a sense of dissonance, which allows the viewer to create his or her own unique interpretation of The Negro Woman.

description: The increasing complexity and modularity of con- temporary systems, paired with increasing parameter variabili- ties, makes the availability of flexible and robust, yet efficient, module-level interconnect instrumental. In this context Globally Asynchronous Locally Synchronous (GALS) systems offer a viable alternative to classical strictly synchronous interconnect. However, with this concept a need for reliable interfaces between different clock and timing domains arises. In this paper we propose a novel approach for timing domain crossing interfaces which are able to safely transfer (read) tokens (i.e., zero-bit messages) from a synchronous into an asynchronous timing domain and vice versa. At its core the new approach uses a Muller pipeline where read tokens are synchronously written to and read from. Doing this in a way that does not lose any tokens, requires the synchronous timing domain to have exact state information about the fill-level of the Muller pipeline (i.e., is it safe to perform a write or read operation). We thoroughly analyze how this state information can be obtained and propose a simple pipeline sampling model. Furthermore we discuss what timing constraints these concepts rely on and how to deal with metastability that inevitably appears at such interfaces. One possible use of the proposed structures is the control path of synchronous/asynchronous or bisynchronous FIFOs, which we use to illustrate the principle and show the practical feasibility.

description: This study examines the racialization of Muslims in the US and what it means for the positioning of Muslims within the US racial framework. I conduct content and discourse analysis of mainstream media representations of Islam and Muslims in newspaper articles, randomly sampling articles from three mainstream newspapers over the period of three years before and after 9/11 to investigate the following research questions: How are Muslims and Islam racialized before and after 9/11? Have there been any shifts in representation during this time period? While a number of studies have conducted content analysis to analyze Muslim racialization, they have focused on "Arabs and Muslims," and thus left African American Muslims outside of their analysis. My primary finding is that Muslims across racial groups are racialized as foreign to the US, and that the ways in which they are racialized as foreign depends on their "actual" race/ethnicity.

description: The purpose of this study was to observe whether or not senior (grade 11 and 12) math students’ motivational levels and the value that they placed on math would increase if a weekly communication occurred between parents and their math teacher. The communication would give the parents information about their child’s present mark in math class and marks on any recent assessments (quiz and test), upcoming assessment dates, possible solutions to increase their child’s present math mark (rewrites, etc.) and recent attendance. This study was done in two different math classes: Math 12 Applications (middle stream in grade 12) and Math 11 Principles (highest stream in grade 11) and included 35 student participants. The study occurred from September 28th until November 9th, 2010 at Alberni District Secondary School. A questionnaire (Appendix C) was completed by the participants three times during the time-series study and the means from the study were analysed to see if change occurred. Positive change occurred in students’ motivation to study for quizzes and tests, and the value that they placed on math in and outside of school.

description: Current template-based gravitational wave searches for compact binary coalescences (CBC) use waveform models that neglect the higher order modes content of the gravitational radiation emitted, considering only the quadrupolar $(\ell,|m|)=(2,2)$ modes. We study the effect of such a neglection for the case of aligned-spin CBC searches for equal-spin (and non-spinning) binary black holes in the context of two versions of Advanced LIGO: the upcoming 2015 version, known as early Advanced LIGO (eaLIGO) and its Zero-Detuned High Energy Power version, that we will refer to as Advanced LIGO (AdvLIGO). In addition, we study the case of a non-spinning search for initial LIGO (iLIGO). We do this via computing the effectualness of the aligned-spin SEOBNRv1 ROM waveform family, which only considers quadrupolar modes, towards hybrid post-Newtonian/Numerical Relativity waveforms which contain higher order modes. We find that for all LIGO versions, losses of more than $10\%$ of events occur for mass ratio $q\geq6$ and $M \geq 100M_\odot$ due to the neglection of higher modes. Moreover, for iLIGO and eaLIGO, losses notably increase up to $(39,23)\%$ respectively for the highest mass $(220M_\odot)$ and mass ratio ($q=8$) studied. For the case of early AdvLIGO, losses of $10\%$ occur for $M>50M_\odot$ and $q\geq6$. Neglection of higher modes leads to observation-averaged systematic parameter biases towards lower spin, total mass and chirp mass. For completeness, we perform a preliminar, non-exhaustive comparison of systematic biases to statistical errors. We find that, for a given SNR, systematic biases dominate over statistical errors at much lower total mass for eaLIGO than for AdvLIGO.

title: On the Effects of Permanent Faults in QDI Circuits - A Quantitative Perspective

Subjects: permanent faults

description: With their event-driven nature, quasi-delay- insensitive (QDI) asynchronous circuits offer a compelling fail-stop behavior along with an inherent 100% permanent fault detection coverage. In fact, permanent faults break the handshake, pushing the circuit into deadlock. In this paper we give quantitative results for the relative occurrence of the different effects that can manifest in a QDI circuit due to permanent faults. We study in which and how many cases the state of the circuit gets corrupted before reaching the deadlock. This behavior diagnosis enables us to identify the cases in which the circuit can go back to operating normally if a (self-) repair process were to take place. This investigation is conducted through extensive fault injection experiments in a chosen circuit simulation. Stuck-at faults are injected on a gate-level VHDL model of the circuit, with a wide coverage of parameters.

description: We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system. We secured high-resolution spectra of HD 161853 during the past nine years. We separated the two components in the system and measured their respective radial velocities for the first time. We confirm that HD 161853 is an $\sim$1 Ma old binary system consisting of an O8 V star ($M_{\rm A,RV} \geq 22$ M$_\odot$) and a B1--3 V star ($M_{\rm B,RV} \geq 7.2$ M$_\odot$) at about 1.3 kpc. From the radial velocity curve, we measure an orbital period $P$ = 2.66765$\pm$0.00001 d and an eccentricity $e$ = 0.121$\pm$0.007. Its $V$-band light curve is constant within 0.014 mag and does not display eclipses, from which we impose a maximum orbital inclination $i=54$ deg. HD 161853 is probably associated with an H II region and a poorly investigated very young open cluster. In addition, we detect a compact emission region at 50 arcsec to HD 161853 in 22$μ$m-WISE and 24$μ$m-Spitzer images, which may be identified as a dust wave piled up by the radiation pressure of the massive binary system.

Studies of Pneumococcal Populations: from Genetic Loci to Coordination Pathways and Interkingdom Interactions

description: The human pathobiont Streptococcus pneumoniae (Spn) is a common colonizer of the nasopharynx but can cause invasive disease upon dissemination into other body sites. As such, Spn employs a wide range of molecular mechanisms to quickly respond to the diverse and ever-changing host environment and to interact with other resident microbes. This work outlines three aspects that contribute to the Spn bimodal lifestyle. To respond to environmental cues, Spn utilizes several cell-cell communication systems. Here, we addressed the question of how Spn may coordinate multiple communication systems from diverse protein families. We identified a transporter with a dual mode of action: it activates one communication system and delays another during infection. Ultimately, this shared molecular link coordinates bacterial communication and subsequent phenotypic responses in the host. Next, we explored Spn population level behaviors from the perspectives of genes, mechanisms, and regulation. We performed detailed comparative genomic analyses of the rtg locus that encodes a cell-cell communication system and a set of exported peptides. This characterization revealed extensive diversity and plasticity in this region and suggested that the peptides function in competition across strains and/or species. Overall, the genomic locus captured flexibility and modularity at the pangenome level and sets the stage to explore functional consequences of peptide secretion to bacterial communities. Secondary bacterial infection is a common and serious complication of Influenza A Virus (IAV) infection. We employed a ferret model to investigate growth and airborne transmission of Spn and IAV during coinfections. Our model captured the increased morbidity associated with coinfection relative to single infections. Moreover, Spn loads, and airborne transmission were increased by the virus, while, surprisingly, IAV titers in nasal fluids were significantly decreased during coinfection. Thus, our work revealed an asymmetric relationship between the two pathogens, rather than a synergistic one since secondary bacterial infection enhances Spn colonization and pathogenesis but decreases viral titers. In summary, this thesis is a lens into Spn genes, pathways, and host-associated phenotypes and their connection to and interactions with diverse host environments and resident microbes.

description: Within the factorization-assisted topological-amplitude approach, we study the two-body charmed $B$ meson decays $B_{u,d,s} \to D^{(*)}M$, with $M$ denoting a light pseudoscalar (or vector) meson. The meson decay constants and transition form factors are factorized out from the hadronic matrix element of topological diagrams. Therefore the effect of SU(3) symmetry breaking is retained, which is different from the conventional topological diagram approach. The number of free nonperturbative parameters to be fitted from experimental data is also much less. Only four universal nonperturbative parameters $χ^C$, $ϕ^C$, $χ^E$ and $ϕ^E$ are introduced to describe the contribution of the color suppressed tree and $W$-exchanged diagrams for all the decay channels. With the fitted parameters from 31 decay modes induced by $b\to c$ transition, we then predict the branching fractions of 120 decay modes induced by both $b\to c$ and $b\to u$ transitions. Our results are well consistent with the measured data or to be tested in the LHCb and Belle-II experiments in the future. Besides, the SU(3) symmetry breaking, isospin violation and $CP$ asymmetry are also investigated.

description: Both adults and adolescents with sickle cell disease (SCD) tend to show better adjustment when using cognitive-behavioral coping strategies during SCD pain episodes. However, little is known about how daily coping affects the relationship between SCD pain and adjustment. For the present study, cognitive-behavioral coping strategies were hypothesized to moderate the relationship between daily SCD pain and mood, activity level, and use of health care resources. Additionally, distraction, relaxation and cognitive restructuring were hypothesized to attenuate the pain-adjustment relationship significantly more than other strategies. Multilevel models were developed to analyze an archival data set of daily diaries from 56 adults and 54 adolescents with SCD. The results indicated that the impact of coping strategies varied between outcomes; occasionally, strategies that related to benefits for one outcome showed costs for another. The findings suggest that for optimal adjustment, individuals should select coping strategies based on their appropriateness for their current situation.
