description: Udotea dotyi D.S. Littler & M.M. Littler 1990: 223
Type Locality:— GRENADINES. Lesser Antilles, Tobago Cays.
 Morphology: — Thalli to 11 cm tall, anchored to the substrata by a bulbous mass of rhizoids. Stipe flattened and robust, 8–13 mm length, 3–5 mm diameter, there is no differentiation between the stipe and blade. Blade fan-shaped, occasionally lobed, green, slightly longer (7–10 cm) than wider (6–7.5 cm), lower margin ovate or truncate, multistratose, corticate, heavily calcified, and faint concentric zonation (Fig. 41).
 Anatomy:—Blade siphons with lateral appendages, 20–40 μm in diameter, densely covered by two opposite rows of short lateral appendages (Fig. 42) with irregular flat apices, blade appendages peduncle 15–30 μm in diameter, 60–120 μm length (Fig. 43). Stipe siphons adjacent to lateral appendages 40–70 μm in diameter, appendages peduncle 150–300 μm length, 20–40 μm in diameter. Appendages branched twice, terminating in numerous blunt rounded tips (Fig. 44).
 Reproduction: — The terminal portions of the blade siphons are transformed into sexual reproductive organs named gametangia.
 Material examined: — MEXICO. Quintana Roo, Uvero, 20 June 2010, J. A. Acosta Calderón, L. E. Mateo Cid, A. C. Mendoza González, ENCB 23133. MEXICO. Campeche, Xpicob, 25 June 2016, J. A. Acosta Calderón, L. E. Mateo Cid, A. C. Mendoza González, ENCB 23132.
 Geographic distribution: — Honduras, Panama, Cuba, Haiti, Lesser Antilles, Puerto Rico, Mexico.
 Habitat: — Sandy bottom with sea grass. Subtidal to 3 m depth.
 Comments:— Udotea dotyi can be confused with U. flabellum because both possess a corticated fan-shaped blade, but the arrangement and shape of the blade’s lateral appendages are clearly different between these species. On the other hand, U. dotyi and U. dixonii possess blade siphons covered with two rows of lateral appendages, nevertheless the shape of the blade’s lateral appendages is different. The shape of the blade and stipe appendages agrees with those described by Littler & Littler (1990). The diameter of blade and stipe siphons is less than those recorded in specimens from Haiti and Honduras (Littler & Littler 1990), buy are like those recorded in algae from Quintana Roo, Mexico (Collado-Vides et al. 2009). Udotea dotyi was an uncommon species in the study area and is recorded for the first time for the Campeche littoral.

Savage, Brainwashed, or Just Like Me: Moral Disagreement Increases External Attribution for Beliefs
Creators: name: Roof, Courtney
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Morality seemingly creates a great cultural divide (Haidt, 2012) — people are pro-choice or pro-life, for traditional marriage or for equality, and for or against the death penalty. Our understanding of these moral disagreements has important and sometimes even grave implications for how we treat others. The present study builds a novel model of belief attribution of moral disagreements. We propose that people attribute moral beliefs to one of three sources: savage tendencies, external factors or internal beliefs. In two experiments, one open-ended and one more quantitative, we explored how people attribute moral beliefs. The findings from our study suggested that participants do tend to attribute their beliefs and the beliefs of those who agree with them to more internal reasons than the beliefs of those who disagree with them for issues such as same-sex marriage and abortion. Additionally, character of the individual had only some effects on belief attribution. These findings inform how we understand moral debates, and future research can apply these results to investigate the role of strength of beliefs, differences across cultures, and even how research in morality is conducted.

description: We illustrate how the Conformal Ward Identities (CWI) in momentum space for parity-odd correlators determine the structure of a chiral anomaly interaction, taking the example of the VVA (vector/vector/axial-vector) and AAA correlators in momentum space. Only the conservation and the anomalous WIs, together with the Bose symmetry, are imposed from the outset for the determination of the correlators. We use a longitudinal/transverse decomposition of tensor structures and form factors. The longitudinal (L) component is fixed by the anomaly content and the anomaly pole, while in the transverse (T) sector we define a new parameterization. We relate the latter both to the Rosenberg original representation of the VVA and to the longitudinal/transverse (L/T) one, first introduced in the analysis of $g-2$ of the muon in the investigation of the diagram in the chiral limit of QCD. The correlators are completely identified by the conformal constraints whose solutions are fixed only by the anomaly coefficient, the residue of the anomaly pole. In both cases, our CFT result matches the one-loop perturbative expression, as expected. The CWIs for correlators of mixed chirality $J_L J J_R$ generate solutions in agreement with the all-orders nonrenormalization theorems of perturbative QCD and in the chiral limit.

description: Within the framework of augmented version of the superfield approach to Becchi-Rouet-Stora-Tyutin (BRST) formalism, we derive the superspace unitary operator (and its Hermitian conjugate) in the context of four (3 + 1)-dimensional (4D) interacting non-Abelian 1-form gauge theory with Dirac fields. The ordinary 4D non-Abelian theory, defined on the flat 4D Minkowski spacetime manifold, is generalized onto a (4, 2)-dimensional supermanifold which is parameterized by the spacetime bosonic coordinates x^μ(with μ= 0, 1, 2, 3) and a pair of Grassmannian variables (θ, \barθ) which satisfy the standard relationships: θ^2 = {\barθ}^2 = 0, θ\,\barθ+ \barθ\,θ= 0. Various consequences of the application of the above superspace (SUSP) unitary operator (and its Hermitian conjugate) are discussed. In particular, we obtain the results of the application of horizontality condition (HC) and gauge invariant restriction (GIR) in the language of the above SUSP operators. One of the novel results of our present investigation is the derivation of explicit expressions for the SUSP unitary operator (and its Hermitian conjugate) without imposing any Hermitian conjugation condition from outside on the parameters and (super)fields of the supersymmetric version of our 4D interacting non-Abelian 1-form theory with Dirac fields.

description: Vortices in fluids and gases have piqued the interest of human for centuries. Development of classical-wave physics and quantum mechanics highlighted wave vortices characterized by phase singularities and topological charges. In particular, vortex beams have found numerous applications in modern optics and other areas. Recently, optical spatiotemporal vortex states exhibiting the phase singularity both in space and time have been reported. Here, we report the first generation of acoustic spatiotemporal vortex pulses. We utilize an acoustic meta-grating with mirror-symmetry breaking as the spatiotemporal vortex generator. In the momentum-frequency domain, we unravel that the transmission spectrum functions exhibit a topological phase transition where the vortices with opposite topological charges are created or annihilated in pairs. Furthermore, with the topological textures of the nodal lines, these vortices are robust and exploited to generate spatiotemporal vortex pulse against structural perturbations and disorder. Our work paves the way for studies and applications of spatiotemporal structured waves in acoustics and other wave systems.

Impact of Short-term Calorie Restriction on HER2-Overexpressing Breast Cancer
Creators: name: Rainey, Magdalena
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Background: Among American women, 30% of all new cancer diagnoses are of breast cancer (BC) and ~25% of these cancers overproduce the growth-promoting tyrosine kinase receptor, HER2. Although there are targeted treatments available for HER2-overexpressing BC, this disease is associated with poorer prognosis and increased risk of recurrence, making identification of new treatment methods crucial. It is well-established that calorie restriction (CR), or chronic dietary energy restriction by ~30%, has significant tumor suppressive effects across cancer subtypes and has potential to be utilized as an adjunctive therapy. This study investigates the mechanisms by which CR decreases HER2-overexpressing BC progression.Methods: To mimic CR in vitro, murine MMTV-neu cells that overexpress HER2 were treated with medias containing reduced serum (1%), reduced glucose (1mM), or reduced serum and reduced glucose (1%/1mM) compared to control media (10% serum, 25mM glucose). The impact of differential nutrient restriction on MMTV-neu regulatory mechanisms was characterized using MTT assays, anchorage independent colony formation assays, cell cycle analysis, and apoptosis assays. To investigate the mechanism of this alteration, western blotting analysis of proteins along the PI3K/Akt and Ras/Erk pathways was conducted. The efficacy of nutrient restriction as an adjunct therapy was explored by treating cells cultured in restricted medias with lapatinib, doxorubicin, and cyclophosphamide.Results: Serum restriction significantly reduced cellular viability and colony formation of MMTV-neu cells and promoted increased cellular apoptosis, and G0/G1 cell cycle arrest. In MMTV-neu cells treated with serum restricted medias (1% and 1%/1mM), there was a significant decrease in activity of tumor-suppressor protein p21. Both p21 and phospho-21 expression was decreased with serum restriction, as well as the proportion of phospho-p21 relative to p21 (p<0.05). Serum and glucose restriction (1%/1mM) increased the sensitivity of MMTV-neu cells to treatment with lapatinib and cyclophosphamide, resulting in reduced cellular viability (p<0.05).Conclusion: These results suggest that short-term CR, achieved specifically through serum restriction alone or in combination with glucose restriction, is associated with decreased phosphorylation and cytoplasmic localization of p21, which may be responsible for modulating anti-proliferative activities. This finding is significant because clinical studies have found that increased cytoplasmic p21 in HER2-overexpressing BC predicted reduced survival in patients at 5 years. Utilizing CR in conjunction with existing therapies may prevent or reverse cytoplasmic p21 localization in this cancer subtype, highlighting the importance of this investigation.
The Effect of COPD on the Immune Response to Influenza Virus Vaccination
Creators: name: Rossitch, Elizabeth Goodall
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Chronic Obstructive Pulmonary Disease (COPD) is a health concern worldwide and particularly in the United States. It is the currently the fourth leading cause of death in the world and is predicted to become the third leading cause of death by 2030. People with COPD often experience exacerbations, an acute onset of more severe symptoms, caused by infections-bacterial and viral. These exacerbations decrease quality of life and further disease progression. Not to mention, while healthy individuals can easily recover from an influenza, it could be deadly in COPD patients. Thus, it is important to ensure that individuals with COPD are adequately covered by influenza vaccination. Currently, little is known about how COPD impacts the cell-mediated immune response, but gaining this knowledge would help determine if individuals with COPD are effectively covered by the vaccine.
The purpose of this pilot study was to determine if COPD affects the cell-mediated immune response post influenza vaccination. Specifically, it aimed to discover if the percentage of CD3+CD8+ T cells were the same in individuals with and without COPD. Additionally, it aimed to assess the ability of these CD3+CD8+ T cells to secrete IFNγ and TNFα. A total of 8 participants were included in the analyses of this study- 3 with COPD and 5 with no respiratory history. Peripheral blood mononuclear cells (PBMCs) were isolated from blood samples 28-35 days post-vaccination and incubated for 120 hours with and without (in two separate wells) the
A/Victoria/361/2011. The cells were stained for CD3, CD8, TNFα, and IFNγ using human fluorochrome-conjugated human antibodies.
There was no significant difference in the CD3+CD8+ T cell percentage between COPD and non-COPD groups, but the percent increase of CD3+CD8+ T cells secreting TNFα and IFNγ when stimulated with in vivo with A/Victoria/361/2011 was significantly greater in the non-COPD group. This suggests that there might be a problem in CD3+CD8+ T cell function in individuals with COPD. Therefore, there need to be further studies to determine whether COPD patients are adequately covered by the current influenza vaccination.

This allows to establish a mapping between the initial electronic system and a spin model including up to quadratic interactions between the effective spins, with a general interaction (exchange) tensor that accounts for anisotropic exchange, Dzyaloshinskii-Moriya interaction and other symmetric terms such as dipole-dipole interaction. We present the formulas in a format that can be used for computations via Dynamical Mean Field Theory algorithms.

description: We propose a new protocol for thr manipulation of a three-level artificial atom in Lambda ($Λ$) configuration in the absence of a direct pump coupling. It allows faithful, selective and robust population transfer analogous to stimulated Raman adiabatic passage ($Λ$-STIRAP), in highly noise protected superconducting artificial atoms. It combines the use of a two-photon pump pulse with suitable advanced control, operated by a slow modulation of the phase of the external fields, leveraging on the stability of semiclassical microwave drives. This protocol is a building block for novel tasks in complex quantum architectures. Its demonstration would be a benchmark for the implementation of a class of multilevel advanced control procedures for quantum computation and microwave quantum photonics in systems based on artificial atoms.

We present a set of field theory examples with fermionic higher-form symmetries, which are constructed from fermionic tensor fields. They include the free fermionic tensor theories, a new type of fermionic topological quantum field theories, as well as the exotic 6d (4,0) theory. We also discuss the gauging and breaking of such global symmetries and the relation to the no global symmetry swampland conjecture.

description: We present first-principles calculations of electronic structures of a class of two-dimensional (2D) honeycomb structures of group-V binary compounds. Our results show these new 2D materials are stable semiconductors with direct or indirect band gaps. The band gap can be tuned by applying lattice strain. During their stretchable regime, they all exhibit metal-indirect gap semiconductor-direct gap semiconductor-topological insulator (TI) transitions with increasing strain from negative (compressive) to positive (tensile) values. The topological phase transition results from the band inversion at $Γ$ point due to lattice strain and is irrelevant to spin-orbit coupling (SOC).

description: The focus of this work is on the design of Raptor codes for continuous variable Quantum key distribution (CV-QKD) systems. We design a highly efficient Raptor code for very low signal to noise ratios (SNRs), which enables CV-QKD systems to operate over long distances with a significantly higher secret key rate compared to conventional fixed rate codes. The degree distribution design of Raptor codes in the low SNR regime is formulated as a linear program, where a set of optimized degree distributions are also obtained through linear programming. Simulation results show that the designed code achieves efficiencies higher than 94\% for SNRs as low as -20 dB and -30 dB. We further propose a new error reconciliation protocol for CV-QKD systems by using Raptor codes and show that it can achieve higher secret key rates over long distances compared to existing protocols.

description: We develop a resource-theoretic framework that allows one to bridge the gap between two approaches to quantum thermodynamics based on Markovian thermal processes (which model memoryless dynamics) and thermal operations (which model arbitrarily non-Markovian dynamics). Our approach is built on the notion of memory-assisted Markovian thermal processes, where memoryless thermodynamic processes are promoted to non-Markovianity by explicitly modelling ancillary memory systems initialised in thermal equilibrium states. Within this setting, we propose a family of protocols composed of sequences of elementary two-level thermalisations that approximate all transitions between energy-incoherent states accessible via thermal operations. We prove that, as the size of the memory increases, these approximations become arbitrarily good for all transitions in the infinite temperature limit, and for a subset of transitions in the finite temperature regime. Furthermore, we present solid numerical evidence for the convergence of our protocol to any transition at finite temperatures. We also explain how our framework can be used to quantify the role played by memory effects in thermodynamic protocols such as work extraction. Finally, our results show that elementary control over two energy levels at a given time is sufficient to generate all energy-incoherent transitions accessible via thermal operations if one allows for ancillary thermal systems.

description: Greenberger-Horne-Zeilinger and W states feature genuine tripartite entanglement that cannot be converted into each other by local operations and classical communication. Here, we present a dissipative protocol for deterministic interconversion between Greenberger-Horne-Zeilinger and W states of three neutral $^{87}$Rb atoms arranged in an equilateral triangle of a two-dimensional array. With three atomic levels and diagonal van der Waals interactions of Rydberg atoms, the interconversion between tripartite entangled states can be efficiently accomplished in the Floquet-Lindblad framework through the periodic optical pump and dissipation engineering. We evaluate the feasibility of the existing methodology using the experimental parameters accessible to current neutral-atom platforms. We find that our scheme is robust against typical noises, such as laser phase noise and geometric imperfections of the atom array. In addition, our scheme can integrate the Gaussian soft quantum control technique, which further reduces the overall conversion time and increases the resilience to timing errors and interatomic distance fluctuations. The high-fidelity and robust tripartite entanglement interconversion protocol provides a route to save physical resources and enhance the computational efficiency of quantum networks formed by neutral-atom arrays.

"Not in Our District": School Boards, Research Access, and Racial Inequality
Creators: name: Green, Joshua
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: An overview of the literature on the subject shows that there are indeed few studies which focus on school board members and the process by which they make policy decisions; related studies generally focused exclusively on group dynamics instead of the decisions of individual policy-makers. By contrast I am most interested in how individual board members view inequality and the factors that influence those views. Given my interest in research, I am also concerned by the fact that very little education research seems to be implemented in districts around North Carolina. These interests drove the development of my two broad research questions:
1.  What factors influence the way that board members frame and respond to issues of race in their districts?
2.  Specifically, is there evidence to suggest that access to academic research can help board members view racial inequality in a more empirically valid way?
To answer these questions, I interviewed sixteen school board members from seven districts over the course of nine months. Each interview lasted an average of 65 minutes and was semi-structured. Given the paucity of the existing literature, I designed the study, and consequently the interview questions, as an exploratory assessment intended to allow school board members freedom to guide the conversations.

description: We present a study of patterns, formed in drying drops of aqueous gelatin solution containing sodium sulphate. The patterns are highly complex, consisting of a hierarchical sequence of rings which form concentric bands as well as dendritic crystalline aggregates. When the preparation of the complex fluid is done by mixing an aqueous solution of the salt with an aqueous solution of gelatin prepared separately, another feature is observed in the pattern on the dried out drop. This is a viscous fingering pattern, superposed on the series of rings. We try to explain the origin of these two features from a simple physical approach.

description: As Thomas Pearsall lay dying from cancer at Duke Hospital, he reflected back over his time as one of the most important actors in the desegregation of North Carolina schools nearly a quarter of a century earlier. A man who prided himself on his racial tolerance, he was distraught over the idea that African Americans in the state might have misperceived his actions during that time. Though Pearsall honestly believed that he was working to preserve public education in the state, many African Americans disagreed.  They believed that his actions, and those of the special policy committee on desegregation that he chaired, purposely slowed implementation of the Supreme Court’s ruling in Brown and actively made it more difficult for them to access quality education. Pearsall lamented, “they have been much more patient than I ever would have been…. I don’t want to go to the grave feeling I haven’t done the best I could for the blacks.”  His torment was so great that his wife, Elizabeth, felt compelled to call then-Governor of North Carolina, Jim Hunt, and ask him to send “a respectable member of the black community” to come relieve Pearsall of his burden.  Hunt sent a man from Durham, though Elizabeth was at lunch when he visited and, significantly, never felt the need to get his name.  The conversation with this unknown man settled Pearsall’s soul, and he was soon able to pass away in peace.

description: Liquid crystal elastomer films that morph into cones are strikingly capable lifters. Thus motivated, we combine theory, numerics, and experiments to reexamine the load-bearing capacity of conical shells. We show that a cone squashed between frictionless surfaces buckles at a smaller load, even in scaling, than the classical Seide/Koiter result. Such buckling begins in a region of greatly amplified azimuthal compression generated in an outer boundary layer with oscillatory bend. Experimentally and numerically, buckling then grows sub-critically over the full cone. We derive a new thin-limit formula for the critical load, $\propto t^{5/2}$, and validate it numerically. We also investigate deep post-buckling, finding further instabilities producing intricate states with multiple Pogorelov-type curved ridges arranged in concentric-circles or Archimedean spirals. Finally, we investigate the forces exerted by such states, which limit lifting performance in active cones.

Income Distribution And Changing Returns To Education Among Bumiputeras In Malaysia: A Quantile Regression Analysis
Creators: name: Hoo, Yi Rong
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Using subsamples from the Malaysian Household Income Survey in 1995 and 2012, this paper investigates income inequality and returns to education in 1995 and 2012 among the Bumiputeras in Malaysia by calculating income inequality measures and by estimating Mincer wage equations using OLS and quantile regression techniques. The estimates of income inequality measures indicate that income inequality did not change from 1995 to 2012. It is also found that income inequality in urban areas was higher than in rural areas in both years. The findings from the estimates of Mincer wage equations are consistent with the human capital theory. Specifically, it is found that returns to education increase with the level of education in both years. In addition to that, the results indicate that returns to education diminish across the quantiles. In other words, Bumiputeras at the lower quantiles of the income distribution gain more from a given level of education as compared to those at the upper quantiles. These findings suggest that policies should be enacted to promote educational attainment among poorer Bumiputeras. This can perhaps be achieved via more comprehensive needs-based affirmative action policies targeted to this group of Bumiputeras. Extension of governmental scholarships for tertiary education to poorer Bumiputeras can be one example. Similar approaches can also be used to promote admissions of poorer Bumiputeras into public universities.

description: The predictions for transition form factors $γ^*\to γf_2(1270)$ and $γ^*\to γa_2(1320)$ and corresponding $e^+e^-\to γ^*\to f_2γ$ and $e^+e^-\to γ^*\to a_2γ$ cross sections are obtained for the energy region up to $2$ GeV. These predictions are coordinated with the recent Belle data on the $γ^*(Q^2)γ\to f_2$ transition. It is shown that the QCD asymptotics of the amplitudes of the reactions $e^+e^-\to γ^*\to f_2γ$ and $e^+e^-\to γ^*\to a_2γ$ can be reached only by taking into account a compensation of contributions of $ρ(770)$, $ω(782)$ with contributions of their radial excitations. The relation $σ(e^+e^-\to γ^*\to f_2γ)/σ(e^+e^-\to γ^*\to a_2γ)\approx 25/9$, obtained with the help of the $q\bar q$ model of $a_2$ and $f_2$ and QCD, is used to determine the $σ(e^+e^-\to γ^*\to a_2γ)$ at high energies. Recent BABAR measurement of the $e^+e^-\to f_2γ\toπ^+π^-γ$ cross section at $10.58$ GeV gives hope for detailed investigation of the $γ^*(s)\to f_2γ$ and $γ^*(s)\to a_2γ$ transition form factors at high energy region.

description: Quantum annealing is a specialized type of quantum computation that aims to use quantum fluctuations in order to obtain global minimum solutions of combinatorial optimization problems. Programmable D-Wave quantum annealers are available as cloud computing resources which allow users low level access to quantum annealing control features. In this paper, we are interested in improving the quality of the solutions returned by a quantum annealer by encoding an initial state into the annealing process. We explore two D-Wave features allowing one to encode such an initial state: the reverse annealing and the h-gain features. Reverse annealing (RA) aims to refine a known solution following an anneal path starting with a classical state representing a good solution, going backwards to a point where a transverse field is present, and then finishing the annealing process with a forward anneal. The h-gain (HG) feature allows one to put a time-dependent weighting scheme on linear ($h$) biases of the Hamiltonian, and we demonstrate that this feature likewise can be used to bias the annealing to start from an initial state. We also consider a hybrid method consisting of a backward phase resembling RA, and a forward phase using the HG initial state encoding. Importantly, we investigate the idea of iteratively applying RA and HG to a problem, with the goal of monotonically improving on an initial state that is not optimal. The HG encoding technique is evaluated on a variety of input problems including the edge-weighted Maximum Cut problem and the vertex-weighted Maximum Clique problem, demonstrating that the HG technique is a viable alternative to RA for some problems. We also investigate how the iterative procedures perform for both RA and HG initial state encoding on random whole-chip spin glasses with the native hardware connectivity of the D-Wave Chimera and Pegasus chips.

description: We present a cost-effective, simple and fast digital holographic microscopy method based upon Rayleigh-Sommerfeld back propagation for identification of the geometrical shape of a cell. The method was tested using synthetic hologram images generated by ray-tracing software and from experimental images of semi-transparent spherical beads and living red blood cells. Our results show that by only using the real part of the back-reconstructed amplitude the proposed method can provide information of the geometrical shape of the object and at the same time accurately determine the axial position of the object under study. The proposed method can be used in flow chamber assays for pathophysiological studies where fast morphological changes of cells are studied in high numbers and at different heights.

description: Low-power GPUs have become ubiquitous, they can be found in domains ranging from wearable and mobile computing to automotive systems. With this ubiquity has come a wider range of applications exploiting low-power GPUs, placing ever increasing demands on the expected performance and power efficiency of the devices. The LPGPU 2 project is an EU-funded, Innovation Action, 30-month-project targeting to develop an analysis and visualization framework that enables GPU application developers to improve the performance and power consumption of their applications. To this end, the project follows a holistic approach. First, several applications (use cases) are being developed for or ported to low-power GPUs. These applications will be optimized using the tooling framework in the last phase of the project. In addition, power measurement devices and power models are devised that are 10× more accurate than the state of the art. The ultimate goal of the project is to promote open vendor-neutral standards via the Khronos group. This paper briefly reports on the achievements made in the first phase of the project (till month 18) and focuses on the progress made in applications; in power measurement, estimation, and modelling; and in the analysis and visualization tool suite.
Impact of pharmacy-driven transitional interventions in hospitalized patients with psychiatric disorders
Creators: name: Tillman, Frank
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Background: Pharmacy-driven transitions of care (TOC) services for patients with psychiatric disorders have not been systematically evaluated. Objective: The primary objective was to assess the frequency of TOC services that were delivered. Secondary objectives were to evaluate the incidences of psychiatric-associated re-hospitalizations and outpatient clinic follow-up thirty days post-discharge.  Methods: This retrospective, double-cohort study compares adult patients who received at least one pharmacy-driven TOC intervention prior to being discharged from a psychiatric unit between June 1, 2017 and June 30, 2018 to a historical control group that was discharged between June 1, 2016 and May 31, 2017. Interventions included discharge counseling on select high-risk medications, medication barrier assessments, delivery of TOC notes to outpatient providers, post-discharge telephone communication, and bedside delivery of medications.  Results: A total of 157 health records were reviewed. The most common interventions were discharge education (44.2%), bedside delivery of medications (44.2%), and medication barriers assessments (43.3%). Adherence (38.5%) and cost (27.9%) were the most common medication barriers. Thirty-day re-hospitalizations occurred in 32.4% and 15.4% of patients in the control and intervention groups, respectively (P <  0.001). A total of 15.1% and 20.1% of patients presented for outpatient follow-up in the control and intervention groups, respectively (P <  0.001).  Conclusion: The findings demonstrate a significant association between receiving pharmacy-driven transitional interventions and enhanced clinical outcomes for this patient population. Future prospective studies are warranted to further elucidate these observations.

description: The direct correspondence between Co band ferromagnetism and structural parameters is investigated in the pnictide oxides $R$CoPO for different rare-earth ions ($R$ = La, Pr, Nd, Sm) by means of muon-spin spectroscopy and {\it ab-initio} calculations, complementing our results published previously [G. Prando {\it et al.}, {\it Phys. Rev. B} {\bf 87}, 064401 (2013)]. Both the transition temperature to the ferromagnetic phase $T_{_{\textrm{C}}}$ and the volume of the crystallographic unit cell $V$ are found to be conveniently tuned by the $R$ ionic radius and/or external pressure. A linear correlation between $T_{_{\textrm{C}}}$ and $V$ is reported and {\it ab-initio} calculations unambiguously demonstrate a full equivalence of chemical and external pressures. As such, $R$ ions are shown to be influencing the ferromagnetic phase only via the induced structural shrinkage without involving any active role from the electronic $f$ degrees of freedom, which are only giving a sizeable magnetic contribution at much lower temperatures.

Subjects: electric cooking

description: Kenya has 85% electricity coverage with close to 0% electric cooking. It is estimated 13.6MtCO2e of GHG is emitted from the cooking fuel with HAP responsible for 21560 deaths every year. The onstove tool uses cost benefit analysis to estimate the net benefit of various cooking solution.

With the tool, two scenarios were ran to get the maximum benefit of adopting electric cooking. The social Scenario with maximum benefit of environment estimated about 76% adopting electric solution with maximum health benefit, environmental benefit, 48.50MtCO2e avoided and high time savings. Removing all the environmental and health spillage the private scenario adopted 87% LPG with 0% electricity since Kenya energy mix comprises of clean energy.

These scenarios shows Kenya has a great potential of adopting electric cooking with great support of relevant stakeholders.

description: We study the problem of fairly allocating indivisible goods to agents with weights corresponding to their entitlements. Previous work has shown that, when agents have binary additive valuations, the maximum weighted Nash welfare rule is resource-, population-, and weight-monotone, satisfies group-strategyproofness, and can be implemented in polynomial time. We generalize these results to the class of weighted additive welfarist rules with concave functions and agents with matroid-rank (also known as binary submodular) valuations.

Visibilità della fama, infamia della Croce e un nuovo concetto di gloria
Creators: name: Bino, Carla Maria
Publisher: name: Mantichora. Italian Journal of Performance Studies
Year: 2022
Subjects: Visual culture of Middle ages; Infamy; History of fame; Passion narrative.

description: This article aims to discuss the meaning of ‘fame’ as a generator of visibility against the background of the radical change in the dynamics of representation proposed by Christian thought. The first section shows how the concept of earthly fame or ‘vainglory’ is part of a broader discourse on the mechanisms of vision that refer to two opposing orders of knowledge. We will see how this contrast becomes clear when the concept of fame / glory short-circuits with its opposite, infamy, and establishes a new perspective of the gaze. The second section is focused on the paradox of the cross, throne of glory and infamous gallows. This apparently contradictory image is one of the dramaturgical pivots of the Franciscan Passion narrative. Through the story of a naked, miserable and radically humiliated glory, the Order built the script of the “theater of humility” and made it the manifesto of their idea of sequela.
