A Cold, White Light: The Defamiliarizing Power of Death in Tolstoy's War and Peace
Creators: name: Ginocchio, Jessica Lynn
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: In this thesis, I examine the theme of death in War and Peace by Lev Tolstoy. Death in War and Peace causes changes in characters' perception of their own lives, spurring them to live better. Tolstoy is widely understood to embed moral lessons in his novels, and, even in his early work, Tolstoy presents an ideal of the right way to live one's life. I posit several components of this Tolstoyan ideal from War and Peace and demonstrate that death leads characters toward this right way through an analysis of the role of death in the transformations of four major characters--Nikolai, Marya, Andrei, and Pierre.

 Abstract This study investigates the features, functions, and differences of women’s language styles used by female characters of different skin colors in “The Help” movie. The movie was chosen because it involves many female characters and conversations among women of different races which are related to the purpose of this study. The data was collected by using the documentation method and analyzed using qualitative methods based on the theory from Lakoff (1975) about women’s language; both the formal and informal method is used to present the analysis. The result shows there are 22 utterances identified with a total of six of women's language features used by women's characters, namely empty adjective, super polite form, lexical hedges, intensifier, tag question, and hypercorrect grammar. Two categories of functions in the features of women's language are found in this study, that is weakening and strengthening function. However, the most used features that are useful as weakening the function of the speech, namely lexical hedges, tag questions, super polite form, and hypercorrect grammar. There are several differences in the language styles of women characters of different races in this study, such as the differences in the frequency and the features used in women’s language.

description: Traditional mathematical models of Hele--Shaw flow consider the injection (or withdrawal) of an air bubble into (or from) an infinite body of viscous fluid. The most commonly studied feature of such a model is how the Saffman-Taylor instability drives viscous fingering patterns at the fluid/air interface. Here we consider a more realistic model, which assumes the viscous fluid is finite, covering a doubly connected two-dimensional region bounded by two fluid/air interfaces. For the case in which the flow is driven by a pressure difference across the two interfaces, we explore this model numerically, highlighting the development of viscous fingering patterns on the interface with the higher pressure. Our numerical scheme is based on the level set method, where each interface is represented as a separate level set function. We show that the scheme is able to reproduce the characteristic finger patterns observed experimentally up to the point at which one of the interfaces bursts through the other. The simulations are shown to compare well with experimental results. Further, we consider a model for the problem in which an annular body of fluid is evolving in a rotating Hele--Shaw cell. In this case, our simulations explore how either one or both of the interfaces can be unstable and develop fingering patterns, depending on the rotation rate and the volume of fluid present.

"Better the Firing Squad than the Mine Shaft": The Rise and Fall of Militarized Labor Discipline in a Moravian Mining District, 1914-1916
Creators: name: Robertson, John David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This essay argues that a system of militarized labor discipline meant to mobilize the economic potential of the Habsburg state during wartime broke down in the Ostrava-Karviná district in the spring of 1916, and that this breakdown was one facet of the failure of Habsburg attempts to construct a managerial state during the First World War. Labor mobilization was undermined by privation, and thus after 1916 militarized labor discipline began to reduce the state's capacity to mobilize labor. The increasing tension between unbearable wartime conditions and untenable military demands, in the Ostrava-Karviná district as in the Monarchy as a whole, drove the population to act against the state.The mining population's alienation from the state as well as from the war effort also challenged the legitimacy of the state's power to direct and mobilize its citizenry, and thus influenced the Monarchy's collapse.

Consumer behaviour

description: The effects of the rearing system (artificially vs. naturally milk-fed) and the slaughter age (3-weeks milk-fed vs. 3-months pasture-fed) on consumer liking of East-Friesian-cross dairy lamb Longissimus lumborum muscle and its association with lipid content and composition were evaluated. The artificially reared lambs were removed from their dams at 2–3 days of age and reared with cow milk. Intramuscular fat content (2.8%) was similar between treatments. Only 3 of the 25 fatty acids evaluated were influenced by the rearing system and 15 by the slaughter age. The rearing system had a minor impact (p < 0.10), but the slaughter age had a major (p < 0.01) impact on consumer liking. All consumers preferred on average meat from 3-weeks-old lambs. However, based on overall liking scores, Cluster-1 (60% of consumers) preferred meat from 3-weeks-old lambs driven by all sensory attributes but mostly tenderness, whereas Cluster-2 preferred meat from 3-months-old lambs driven by flavor only, indicating a preference for stronger flavor from older lambs finished on pasture. Meat fatty acid profile and consumer liking were not influenced by the rearing system but by lamb slaughter age, showing a niche product opportunity for the 3-weeks milk-fed lambs.

description: The exclusive photoproduction reactions $γp \to J/ψ(1S) p$ and $γp \to ψ(2S) p$ have been measured at an $ep$ centre-of-mass energy of 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 373 pb$^{-1}$. The measurement was made in the kinematic range $30 < W < 180$ GeV, $Q^2 < 1$ GeV$^2$ and $|t| < 1$ GeV$^2$, where $W$ is the photon--proton centre-of-mass energy, $Q^2$ is the photon virtuality and $t$ is the squared four-momentum transfer at the proton vertex. The decay channels used were $J/ψ(1S) \to μ^+ μ^-$, $ψ(2S) \to μ^+ μ^-$ and $ψ(2S) \to J/ψ(1S) π^+ π^-$ with subsequent decay $J/ψ(1S) \to μ^+ μ^-$. The ratio of the production cross sections, $R = σ_{ψ(2S)} / σ_{J/ψ(1S)}$, has been measured as a function of $W$ and $|t|$ and compared to previous data in photoproduction and deep inelastic scattering and with predictions of QCD-inspired models of exclusive vector-meson production, which are in reasonable agreement with the data.

description: Der japanische Kaiser herrscht auf der Basis und mithilfe der Shintô-Zeremonien – trotz der Verfassung. Die Zeremonien haben Vorrang vor jedem anderen Handeln. Tennô tritt sein Amt aufgrund der Shintô-Zeremonien an und wird zum Schluss mit Shintô-Zeremonien beerdigt – auf Kosten des Staates. Die Staatsspitzen nehmen – verfassungswidrig – an den Zeremonien teil. Der Tennô ist außerdem weltlicher Herrscher. Er erhält – unabhängig von der Verfassung – von den zurückgekehrten Botschaftern Einzelheiten über ihre Einsatzorte. Er erfährt – unabhängig von der Verfassung – von den Gouverneuren der einzelnen Präfekturen die Einzelheiten über ihre Probleme. Er erhält – unabhängig von der Verfassung – von der Staatsführung wie aus einzelnen Ministerien vertrauliche Mitteilungen. Der Tennô wird nicht von der Verfassung definiert – wenn er das wäre, wären die nötigen Ausnahmen sehr schwer zu beschreiben – sondern ist in die Verfassung inkorporiert. Wo immer der Tennô in der Verfassung behandelt wird, geschieht das nie aufgrund der Trennungsbestimmungen, sondern immer aufgrund der Civil Religion. Japan gehört einem anderen Religionskreis an als Deutschland. Seine Verfassungsverstöße wären in Deutschland Verfassungsverstöße, in Japan nicht.
description: The Japanese emperor reigns with the help and on the basis of Shintô ceremonies – despite the constitution. The ceremonies have pre-eminence over all other activities. The Tennô begins his career with Shintô ceremonies and is buried according to Shintô rites – at the expense of the state. The rulers of the state participate in the ceremonies – despite the constitution. The Tennô is also secular ruler. He is briefed by the returning ambassadors – outside of the constitution – about the different areas of the world. He is briefed by the governors of the prefectures – outside of the constitution – about the merits and demerits of their prefectures. He receives – outside of the constitution – confidential communications by the government or by different ministries. The position of Tennô is not defined by the constition. If it were, it would be difficult to explain all the exemptions to the constitution. Rather, he is incorporated into the constitution. Whenever the Tennô is acted on by the constitution, he is seen through the lense of Civil Religion and never through the priciples of the separation of state and religion. Japan belongs to a different civilization than Germany. The afore mentioned violations against the constitution would be violations in Germany, they are not in Japan.

description: Age and mass determinations for isolated stellar objects remain model-dependent. While stellar interior and atmospheric theoretical models are rapidly evolving, we need a powerful tool to test them. Open clusters are good candidates for this role. We complement previous studies on the Hyades multiplicity by Lucky Imaging observations with the AstraLux Norte camera. This allows us to exclude possible binary and multiple systems with companions outside 2--7 AU separation and to create a "single-star sequence" for the Hyades. The sequence encompasses 250 main-sequence stars ranging from A5V to M6V. Using the "Tool for Astrophysical Data Analysis" (TA-DA), we create various theoretical isochrones applying different combinations of interior and atmospheric models. We compare the isochrones with the observed Hyades single-star sequence on J vs. J - K_s, J vs. J - H and K_s vs. H - K_s color-magnitude diagrams. As a reference we also compute absolute fluxes and magnitudes for all stars from X-ray to mid-infrared based on photometric measurements available in the literature(ROSAT X-ray, GALEX UV, APASS gri, 2MASS JHK_s, and WISE W1 to W).We find that combinations of both PISA and DARTMOUTH stellar interior models with BT-Settl 2010 atmospheric models describe the observed sequence well. The full sequence covers the mass range 0.13 to 2.3 Msun, and effective temperatures between 3060 K and 8200 K. Within the measurement uncertainties, the current generation of models agree well with the single-star sequence. The primary limitations are the uncertainties in the measurement of the distance to individual Hyades members, and uncertainties in the photometry. Additionally, a small (~0.05 mag) systematic offset can be noted on J vs. J - K and K vs. H - K diagrams - the observed sequence is shifted to redder colors from the theoretical predictions.

Sclerochronology and geochemical variation in limpet shells (Patella vulgata and Patella stellaeformis): evaluating a new proxy for Holocene climate change in coastal areas
Creators: name: Fenger, Tracy Lynn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Before reconstructing potential climate information preserved in Holocene archaeological shells of the European limpet, Patella vulgata, we studied the controls on δ18 and δ13 in modern specimens. We evaluated whether P. vulgata shells precipitate in isotopic equilibrium with the ambient water by comparing δ18OSHELL with expected values. Comparison revealed that δ18OSHELL values were 1.51±0.21‰ higher than expected (corresponding estimated SST was 6.5±2.5 °C lower than observed SST). However, an adjustment can account for this predictable vital effect to reliably reconstruct SST. Tropical species, P. stellaeformis, was evaluated to determine whether it displays a similar positive offset from equilibrium as P. vulgata. We tested the hypotheses that δ18OSHELL in tropical species displays vital effects and the disequilibrium would be constant and predictable. Our results indicated P. stellaeformis δ18OSHELL exhibits a negative offset from expected equilibrium. Differences in mineralogy or growth rates at different latitudes may influence mechanisms that cause vital effects.
Combined effect of beet powder and lentil flour as a partial nitrite substitute on physicochemical, texture and sensory characteristics, color, and oxidative stability of pork bologna

description: The combined effect of beet powder (BP; 0.1%, 0.3%, and 0.5%) and 6% lentil flour (LF) as a partial nitrite substitute on quality attributes of pork bologna incorporated with 7.5% mechanically separated pork during 12 weeks of cold storage was evaluated. A randomized block experimental design with nine treatments and five storage times (0, 3, 6, 9, and 12 weeks) was used for pH, thiobarbituric acid reactive substance, protein oxidation (carbonyl and sulfhydryl), and color parameters. Bologna preparation at a pilot plant scale was replicated three times. LF addition resulted (p < 0.05) in higher viscosity, emulsion stability, and lower expressible drip. Together BP and LF decreased protein oxidation during storage but were not as effective as nitrite with respect to lipid oxidation. Bologna with BP addition showed lower lightness and higher redness, whereas LF increased lightness and decreased redness. A consumer panel rated color acceptability of bologna lower with LF addition, whereas BP raised color acceptability. However, addition of the highest BP level alone to the bologna was negatively perceived as a result of the low acceptability of purge color of the vacuum-packaged bologna slices. Consequently, the combination of BP and LF could be used to improve eating quality and stability attributes when used as a potential nitrite substitute.
The Value of Intercollegiate Athletics Participation from the Perspective of Former Athletes

Year: 2013

description: The vast majority of individuals that have participated in athletics will say that they learned something by participating in athletics, but the question remains, what is it that was really learned? This study provides a valuable addition to the literature related to the educational value of intercollegiate athletics. This study delves into what it is that former student-athletes believe they gained by participating in college athletics. The purpose of this study was to identify the benefits of intercollegiate athletic participation from the perspective of former student-athletes. Four main research questions are answered using the survey responses, which include: educational competencies developed through participation; effect of participation on collegiate academic success; effect of participation on post-graduate opportunities; and the most poignant lessons learned. The quantitative data was used to run various statistical tests including descriptive statistics and ANOVAs, while the qualitative findings were triangulated with the literature and quantitative findings.

description: After extending the Regge-Teitelboim formulation of gravity to include the case where the background embedding space is not flat, we examine the dynamics of the four-dimensional $k=0$ Robertson-Walker (RW) manifold embedded in various five-dimensional backgrounds. We find that when the background is five-dimensional de Sitter space, the RW manifold undergoes a transition from a de-accelerating phase to an accelerating phase. This occurs before the inclusion of matter, radiation or cosmological constant sources, and thus does not require a balance of different components. We obtain a reasonable two-parameter fit of this model to the Hubble parameter data.

description: The parameter-free computation of charge transport properties of semiconductors is now routine owing to advances in the ab-initio description of the electron-phonon interaction. Many studies focus on the low-field regime in which the carrier temperature equals the lattice temperature and the current power spectral density (PSD) is proportional to the mobility. The calculation of high-field transport and noise properties offers a stricter test of the theory as these relations no longer hold, yet few such calculations have been reported. Here, we compute the high-field mobility and PSD of hot holes in silicon from first principles at temperatures of 77 and 300 K and electric fields up to 20 kV cm$^{-1}$ along various crystallographic axes. We find that the calculations quantitatively reproduce experimental trends including the anisotropy and electric-field dependence of hole mobility and PSD. The experimentally observed rapid variation of energy relaxation time with electric field at cryogenic temperatures is also correctly predicted. However, as in low-field studies, absolute quantitative agreement is in general lacking, a discrepancy that has been attributed to inaccuracies in the calculated valence band structure. Our work highlights the use of high-field transport and noise properties as a rigorous test of the theory of electron-phonon interactions in semiconductors.

description: Common-envelope (CE) evolution is an outstanding open problem in stellar evolution, critical to the formation of compact binaries including gravitational-wave sources. In the ``classical'' isolated binary evolution scenario for double compact objects, the CE is usually the second mass transfer phase. Thus, the donor star of the CE is the product of a previous binary interaction, often stable Roche-lobe overflow (RLOF). Because of the accretion of mass during the first RLOF, the main-sequence core of the accretor star grows and is ``rejuvenated''. This modifies the core-envelope boundary region and decreases significantly the envelope binding energy for the remaining evolution. Comparing accretor stars from self-consistent binary models to stars evolved as single, we demonstrate that the rejuvenation can lower the energy required to eject a CE by $\sim 42-96\%$ for both black hole and neutron star progenitors, depending on the evolutionary stage and final orbital separation. Therefore, binaries experiencing first stable mass transfer may more easily survive subsequent CE events and result in possibly wider final separations compared to current predictions. Despite their high mass, our accretors also experience extended ``blue loops'', which may have observational consequences for low-metallicity stellar populations and asteroseismology.

Transition from anti-solar to solar-like differential rotation: Dependence on Prandtl number

Publisher: name: arXiv
Year: 2022
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: (abridged) Context: Late-type stars such as the Sun rotate differentially due to the interaction of turbulent convection and rotation. Aims: The aim of the study is to investigate the effects of the thermal Prandtl number on the transition from anti-solar (slow equator, fast poles) to solar-like (fast equator, slow poles) differential rotation. Methods: Three-dimensional hydrodynamic and magnetohydrodynamic simulations in semi-global spherical wedge geometry are used to model convection zones of solar-like stars. Results: The overall convective velocity amplitude increases as the Prandtl number decreases in accordance with earlier studies. The transition from anti-solar to solar-like differential rotation is insensitive to the Prandtl number for Prandtl numbers below unity but for Prandtl numbers greater than unity, solar-like differential rotation becomes significantly harder to excite. Magnetic fields and more turbulent regimes with higher fluid and magnetic Reynolds numbers help in achieving solar-like differential rotation in near-transition cases. Solar-like differential rotation occurs only in cases with radially outward angular momentum transport at the equator. The dominant contribution to such outward transport near the equator is due to prograde propagating thermal Rossby waves. Conclusions: The differential rotation is sensitive to the Prandtl number only for large Prandtl numbers in the parameter regime explored in the current study. Magnetic fields have a greater effect on the differential rotation, although the inferred presence of a small-scale dynamo does not lead to drastically different results in the present study. The dominance of the thermal Rossby waves in the simulations is puzzling given the non-detection in the Sun. The current simulations are shown to be incompatible with the currently prevailing mean-field theory of differential rotation.

description: In this work we propose a $\mathbb{Z}_N$ clock model which is exactly solvable on the lattice. We find exotic properties for the low-energy physics, such as UV/IR mixing and excitations with restricted mobility, that resemble fractonic physics from higher dimensional models. We then study the continuum descriptions for the lattice system in two distinct regimes and find two qualitative distinct field theories for each one of them. A characteristic time scale that grows exponentially fast with $N^2$ (and diverges rapidly as a function of system parameters) separates these two regimes. For times below this scale, the system is described by an effective fractonic Chern-Simons-like action, where higher-form symmetries prevent quasiparticles from hoping. In this regime, the system behaves effectively as a fracton as isolated particles, in practice, never leave their original position. Beyond the large characteristic time scale, the excitations are mobile and the effective field theory is given by a pure mutual Chern-Simons action. In this regime, the UV/IR properties of the system are captured by a peculiar realization of the translation group.

description: Tight limits on the photon mass have been set through analyzing the arrival time differences of photons with different frequencies originating from the same astrophysical source. However, all these constraints have relied on using the first-order Taylor expansion of the dispersion due to a nonzero photon mass. In this work, we present an analysis of the nonzero photon mass dispersion with the second-order derivative of Taylor series. If the arrival time delay corrected for all known effects (including the first-order delay time due to the plasma and photon mass effects) is assumed to be dominated by the second-order term of the nonzero photon mass dispersion, a conservative upper limit on the photon mass can be estimated. Here we show that the dedispersed pulses with the second-order time delays from the Crab pulsar and the fast radio burst FRB 180916B pose strict limits on the photon mass, i.e., $m_{γ,2} \leq5.7\times10^{-46}\;{\rm kg}\simeq3.2\times10^{-10}\; {\rm eV}/c^{2}$ and $m_{γ,2} \leq6.0\times10^{-47}\;{\rm kg}\simeq3.4\times10^{-11}\; {\rm eV}/c^{2}$, respectively. This is the first time to study the possible second-order photon mass effect.

description: Hosting unique drumhead surface states enclosed by nodal lines, topological nodal-line semimetals exhibit novel transport phenomena. Thus, the exploration of topological semimetals with different nodal-line structures has attracted much attention. In this paper, we first find a second-order nodal line semimetal (SONLS), which has coexisting hinge Fermi arcs and drumhead surface states, in a $\mathcal{PT}$-symmetry broken system. Then, without changing the intrinsic parameters, we artificially create exotic hybrid-order nodal-line semimetals hosted by different quasienergy gaps and rich nodal-line structures including nodal chains, crossing ring nodal nets, crossing line nodes, and nodal nets by applying a periodic driving on our SONLS. Enriching the classification of topological semimetals, such Floquet engineered high tunability of the orders and nodal-line structures of the SONLS sets up a foundation for exploring its further applications.

They can be described by a half-filled single band Hubbard model in which the ratio between the Hubbard, U, and the bandwidth, W, U/W $\approx$ 5 $\sim$ 10. Both Mott and magnetic transitions of the material are calculated by the slave boson mean field theory. Doping the Mott state, a $d_{x^2-y^2}+id_{xy}$ superconducting pairing instability is found. We also construct a tunable bilayer Hubbard system for two sliding Nb$_3$X$_8$ layers. The bilayer system displays a crossover between the band insulator and Mott insulator.

Creators: name: Tharrington, Anna S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The purpose of this study was two-fold: first, to identify the number and types of positions in Division I athletic departments and Division I conference offices that are filled by individuals who have earned a Juris Doctorate degree, and second, to identify the perceptions (both positive and negative) of having such individuals in these departments and offices. One hundred forty-two Division I athletics directors and Division I conference commissioners participated in Survey One and 33 individuals who have earned a Juris Doctorate degree participated in Survey Two. This study provided a glimpse into the existence of those individuals working in Division I college athletics who have earned a Juris Doctorate degree, about whom little previous information was known. Information obtained from respondents includes: perceptions of hiring such individuals, salary ranges, length of employment, previous employment experience, areas of legal counsel, and frequency of legal issues in these departments and offices.

description: The recently proposed semi-blind source separation (SBSS) method for nonlinear acoustic echo cancellation (NAEC) outperforms adaptive NAEC in attenuating the nonlinear acoustic echo. However, the multiplicative transfer function (MTF) approximation makes it unsuitable for real-time applications especially in highly reverberant environments, and the natural gradient makes it hard to balance well between fast convergence speed and stability. In this paper, we propose two more effective SBSS methods based on auxiliary-function-based independent vector analysis (AuxIVA) and independent low-rank matrix analysis (ILRMA). The convolutive transfer function (CTF) approximation is used instead of MTF so that a long impulse response can be modeled with a short latency. The optimization schemes used in AuxIVA and ILRMA are carefully regularized according to the constrained demixing matrix of NAEC. Experimental results validate significantly better echo cancellation performance of the proposed methods.
Regulation of the Epithelial Sodium Channel (ENaC) by the Short Palate, Lung, and Nasal Epithelial Clone (SPLUNC1)

description: The airways rely on mucociliary clearance (MCC) to remove inhaled particulates. Initiating events in chronic airway diseases, such as cystic fibrosis (CF), have been traced back to the failure of a critical MCC component, ion transport. Specifically, the epithelial sodium channel (ENaC) is known to be hyperabsorptive in CF airway epithelia and contributes to dehydrated airway surface liquid (ASL), collapsed cilia, and high percent solid mucus. Recently, proteolytic cleavage and activation of ENaC has been described and SPLUNC1 was identified as an endogenous inhibitor of ENaC activation. Here, we demonstrate SPLUNC1's ability to reduce macroscopic current and specifically the number of channels of membrane-inserted ENaCs. This work also identifies the active site of SPLUNC1 and provides evidence for a functional SPLUNC1 mimetic peptide. Further, as nonfunctional CFTR influences abnormal bicarbonate secretion and thus CF ASL pH, we correlated the loss of SPLUNC1's function in CF airways to this acidic environment.

description: As protein folding is a NP-complete problem, artificial intelligence tools like neural networks and genetic algorithms are used to attempt to predict the 3D shape of an amino acids sequence. Underlying these attempts, it is supposed that this folding process is predictable. However, to the best of our knowledge, this important assumption has been neither proven, nor studied. In this paper the topological dynamic of protein folding is evaluated. It is mathematically established that protein folding in 2D hydrophobic-hydrophilic (HP) square lattice model is chaotic as defined by Devaney. Consequences for both structure prediction and biology are then outlined.

description: The amount of heat an integer quantum Hall edge state can carry in equilibrium is quantized in universal units of the heat flux quantum $J_q= \frac{πk_B^2}{12 \hbar}T^2$ per edge state. We adress the question of how heat transport in realistic one dimensional devices can differ from the usual chiral Luttinger liquid theory. We show that a local measurement can reveal a nonquantized amount of heat carried by the edge states, despite a globally equilibrium situation. More specifically, we report a heat enhancement effect in edge states interacting with ohmic reservoirs in the presence of nonlocal interactions or chirality breaking diffusive currents. In contrast to a nonequilibrium, nonlinear drag effect, we report an equilibrium, linear phenomenon. The chirality of the edge states creates additional correlations between the reservoirs, reflected in a higher than quantum heat flux in the chiral channel. We show that for different types of coupling the enhancement can be understood as static or dynamical backaction of the reservoirs on the chiral channel. We show that our results qualitatively hold by replacing the dissipative ohmic reservoirs by an energy conserving mesoscopic capacitor and consider the respective transmission lines for different types of interaction.

Understanding the Importance of Work-Family Supportive Coworkers in Navigating the Work-Family Interface

description: Coworkers can play an important role in helping each other overcome stressful circumstances (Beehr, Jex, Stacy, & Murray, 2000; LaRocco & Jones, 1978; Viswesvaran, Sanchez, & Fisher, 1999), yet work-family researchers have paid significantly less attention to coworker-provided support than they have to supervisor-provided support (Kossek, Pichler, Bodner, & Hammer, 2011). This thesis contributes to the occupational health literature by providing empirical evidence of the benefits of a novel construct termed work-family supportive coworker behavior (WFSCB) – defined as any supportive action that a coworker can take to contribute to the improved management of an individual’s work and family role demands. A phenomenological qualitative investigation revealed five categories of WFSCB that were tested using three quantitative samples to develop and validate a multidimensional measure. The findings indicated that four dimensions of behavior best reflect WFSCB including: 1) emotional support, 2) facilitating work adjustments, 3) sharing resources and knowledge, and 4) proactively developing solutions. In testing the criterion-related validity of the new measure, this research provides evidence of the positive relationship between these behaviors and various work-family outcomes, as higher levels of WFSCB were associated with lower levels of work-to-family conflict, and higher levels of work-family balance, work-family positive spillover, and overall life satisfaction. In addition, the utility of WFSCB as a source of informal workplace support was underscored based on evidence of its incremental validity in the prediction of these same outcome variables over and above a measure of general coworker support (i.e., emotional and instrumental support). Practically, these findings suggest that general measures of coworker support may fall short in assessing a broad spectrum of supportive coworker behaviors that can significantly contribute to improved work-family outcomes. Overall, the results of this research program will place scholars in a better position to provide prescriptive advice to organizations and employees on the behaviors that they can engage in towards one another to promote improved work-family integration for individuals and more broadly, to contribute to a work-family supportive organizational climate.

description: Thickness scaling of ferroelectricity in AlScN is a determining factor for its potential application in neuromorphic computing and memory devices. In this letter, we report on ultrathin (10 nm) Al0.72Sc0.28N films that are ferroelectrically switchable at room temperature. All-epitaxial Al0.72Sc0.28N/Pt heterostructures are grown by magnetron sputtering onto GaN/sapphire substrates followed by an in situ Pt capping approach to avoid oxidation of the Al0.72Sc0.28N film surface. Structural characterization by X-ray diffraction and transmission electron microscopy reveals the established epitaxy. The thus obtained high-quality interfaces in combination with the in situ capping is expected to facilitate ferroelectric switching of AlScN in the ultrathin regime. The analysis of the relative permittivity and coercive field dependence on the Al0.72Sc0.28N film thicknesses in the range of 100 nm down to 10 nm indicates only moderate scaling effects, suggesting that the critical thickness for ferroelectricity is not yet approached. Furthermore, the deposited layer stack demonstrates the possibility of including ultrathin ferroelectric AlScN into all-epitaxial GaN-based devices using sputter deposition techniques. Thus, our work highlights the integration and scaling potential of all-epitaxial ultrathin AlScN offering high storage density paired with low voltage operation desired for state of the art ferroelectric memory devices.

description: Different hypotheses about a quantum system such as the logical state of a qubit or the value of physical interaction parameters can be investigated by the interaction with a probe field. Such fields may be prepared in particularly sensitive quantum states, and we can use quantum trajectories to model the stochastic measurement record and conditional evolution of the state of the quantum system subject to its interaction with a travelling pulse of radiation. Our analysis applies to different measurement strategies and to arbitrary input quantum states of the probe field pulse and it thus permits direct comparison of their metrological advantages.
