description: Purpose: The purpose of this study was to conduct an integrative review of original research, across adult populations relating to fatal or nonfatal choking on food, to understand ways to respond to and prevent choking incidents.Method: Four scientific databases (CINAHL, Medline, Web of Science, and EMBASE) were searched for original peer-reviewed research relating to fatal or nonfatal choking on foods. Data were extracted on study characteristics; factors leading up to, events at the time of, and actions taken after the choking incident; and impacts of choking incidents. An integrative review of the findings across studies identified several risk factors and recommendations to reduce the risk of choking.Results: In total, 52 studies met the criteria for inclusion in this review, of which 31 were quantitative, 17 were qualitative, and 4 were of a mixed methods design. Studies reported the observations and narratives of bystanders or researchers, or else were large-scale autopsy studies, and included both the general public and people at risk of dysphagia. A range of food types were involved, and several actions were reported in response to food choking. Strategies to reduce the risk of choking were identified in the studies and are presented in 5 main categories.Conclusions: Factors leading up to choking incidents extend well beyond the individual to the environment for mealtimes; the provision of appropriate mealtime assistance and oral care; and regular monitoring of general health, oral health, and medications. Bystanders’ increased awareness and knowledge of how to respond to choking are vital. The results of this review could be used to inform service policy and training, for individuals at risk of choking, the people who support them, and the general public. Further research is needed to explore choking prevention and airway protection in individuals with dysphagia.

The use of guided imagery to improve pain and anxiety in same-day surgery patients at the Veterans Administration New Jersey Health Care System. Phase II
Creators: name: Vintilescu, Constantin
Publisher: name: No Publisher Supplied
Year: 2021

description: This Phase II DNP project is a Health Care Delivery Innovation a continuation of a pilot project, which introduced a low-cost easily taught kit to deliver a guided imagery session to pre-surgical patients at the Veterans Administration hospital on the day of surgery to improve pain and anxiety. The pilot project established that the kit which included an MP3 player with Belleruth Naparstek’s “Meditation to Promote Successful Surgery,” delivered on the day of surgery and reinforced for 7 days post-op, was an effective, low cost, easily taught, sustainable method to improve pain and anxiety in Same-Day Surgery Patients in a small sample size of Veterans, n=21. The Health Care Delivery Innovation objective is to reproduce the success of the guided imagery project but established in a larger sample size (n=40) and to improve on the original project design in preparation for Phase III streamlined nationwide implementation for wider dissemination. The Department of Defense (D o D), and Veteran Administration (VA) pain scale and the State-Trait Inventory Marteau & Bekker, (STAI) will be used to measure pain and anxiety upon check-in on the same day of surgery, after initial implementation before being called to surgery, and 7 days post-surgery.
A new class of unstable modes of rotating relativistic stars

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The first numerical study of axial (toroidal) pulsation modes of a slowly rotating relativistic star is presented. The calculation includes terms of first order in $ε\equiv Ω\sqrt{R^3/M}<<1$ ($R$ is the radius, $M$ is the mass and $Ω$ is the rotation frequency of the star), and accounts for effects due to the coriolis force. Effects due to the centrifugal flattening of the star enter at order $ε^2$ and are not included in the analysis. It is shown that increased rotation tends to decrease the damping times for prograde modes, while retrograde become longer lived. Specifically, we show that rotation affects the axial gravitational-wave $w$-modes in this way. We also present the first relativistic calculation of the so-called $r$-modes (analogous to Rossby waves in the Earth's oceans). These have frequencies of the same order of magnitude as the rotation frequency of the star. The presented results indicate that the $r$-modes are unstable due to the emission of gravitational radiation for \underline{all} rotating perfect fluid stars. This is interesting since the previously considered gravitational-wave instability associated with (for example) the $f$-mode of the star sets in at a critical rotation rate. Because they are unstable also for the slowest rotating stars the $r$-modes may well be of considerable astrophysical importance.

description: Excerpts from the report: Food served in schools is an important segment of the away-from-home eating market. Further expansion is likely to take place as new schools are constructed with modern cooking and cafeteria facilities and as school enrollments continue to rise. This study on food in schools was undertaken as a part of a broad program of research to expand markets for farm products. The research attempts to chart the current and potential size of the market for food in public elementary and high schools for food manufacturers and distributors as well as Department, State, and local officials responsible for school feeding programs. Of the 106,000 public schools below the college level, approximately 60,000 were offering a lunch service during the period July 1957 through June 1958. About 54,000 of the public schools with a lunch service participated in the National School Lunch Program. The sample consisted of 500 public schools having a food service. The schools were selected on an area probability basis and the sample data projected to universe totals. The basic purpose of the study was to determine the quantities and wholesale value of the different foods, both purchased and donated, delivered to schools, and the buying practices and market channels used in acquiring food.

Struggle to Control Black Leadership: A Study in Community Power
Creators: Brown, Tommie F.
Publisher: name: Columbia University
Year: 1984
Subjects: Social service
African Americans

description: An extraordinary number of scholarly works have been produced about community-level power in America. The focus of attention, however, has been primarily upon the Anglo-Saxon community. Virtually all these reports contained serious inaccuracies about black leaders. Where exceptions existed they were based solely upon data gathered during the legally sanctioned biracial system or immediately thereafter.

Conclusions about contemporary blacks tend to rely upon these earlier, suspect explanations. The most persistent theme can be stated as "black leadership is chaotic, episodic, non-representative, ineffective and uncontrolled by the black community."

This appalling lack of knowledge about contemporary black leadership has provided the framework for the case study of a medium sized southeastern United States city, Chattanooga, Tennessee. Twin (although not identical) hypotheses underlie the study:

First, efforts made by black and white communities to designate and control the actions of black leaders resulted in a bifurcated leadership structure. The findings of the study were that the interpenetration between the black and white communities altered and affected the patterns of power and influence in each.

Second, these two designated black leadership segments took different positions on issues because they represented the interests of different constituencies. The three operative variables--the years 1970-79, black leadership and designation sources--were measured with a range of data and methodologies. For example, modified-stratified samples of 29 white and 57 black respondents were used. Data extracted from newspapers and organization records were correlated with issues, events, and leaders and their activities.

The research data supported the major hypotheses, revealing that whites employed five major strategies which weakened and, at times, defeated blacks' goals. Evidence emerged to substantiate the existence of a decidedly cohesive black leadership which fashioned a set of skillfully designed and executed strategies while simultaneously coping with a counter black leadership structure supported by the white leadership.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Im Leben des Menschen haben Pflanzen seit jeher eine große Bedeutung gehabt. Als Lieferanten vielseitig nutzbarer Biomasse waren sie eine wesentliche Grundlage für die Ernährung von Mensch und Haustier ebenso wie für die Energieerzeugung. Zugleich lieferten sie Werkstoffe, Baumaterial, Fasern sowie Grundlagen für Heildrogen und Farbstoffe. Schließlich hatten viele Pflanzen auch eine Bedeutung im Zusammenhang mit religiösen Vorstellungen bzw. dienten als Schmuck. Erst in jüngerer Zeit sind die vielfältigen Nutzungsmöglichkeiten der Pflanzen in den Hintergrund gedrängt worden. Dies beruht wohl weitgehend auf der durch Chemie und Technologie ermöglichten Erschließung fossiler Biomassereste (Kohle und Erdöl -> Kunststoffe) und deren umfangreicher Nutzung. Daher werden Pflanzen heutzutage oftmals nur noch als Lieferanten von Nahrungsmitteln und Blumenschmuck betrachtet.
Fossile Pflanzenreste, die bei archäologischen Ausgrabungen erschlossen werden können, bieten daher günstige Voraussetzungen, um Einblicke in die Lebensmöglichkeiten des Menschen in vergangenen Zeiten zu erhalten. Pflanzen sind zugleich auch gute Indikatoren für die physiogenen und anthropogenen Standortsbedingungen an ihren Wuchsorten. Die Auswertung fossiler Pflanzenreste kann daher zusätzlich über die frühen Umweltverhältnisse und insbesondere über die landwirtschaftlichen Produktionsverhältnisse informieren.
Mit der Untersuchung derartiger Pflanzenfunde und den genannten Auswertungsmöglichkeiten befaßt sich die Paläo-Ethnobotanik. Dies ist eine interdisziplinär orientierte Teildisziplin der Botanik, die sich um Erkenntnisse über die frühen Lebensumstände des Menschen ebenso bemüht wie um die Erschließung früher Umweltverhältnisse.

The notion of observable and the moment problem for *-algebras and their GNS representations

description: We address some usually overlooked issues concerning the use of $*$-algebras in quantum theory and their physical interpretation. If $\mathfrak{A}$ is a $*$-algebra describing a quantum system and $ω\colon\mathfrak{A}\to\mathbb{C}$ a state, we focus in particular on the interpretation of $ω(a)$ as expectation value for an algebraic observable $a=a^*\in\mathfrak{A}$, studying the problem of finding a probability measure reproducing the moments $\{ω(a^n)\}_{n\in\mathbb{N}}$. This problem enjoys a close relation with the self-adjointeness of the (in general only symmetric) operator $π_ω(a)$ in the GNS representation of $ω$ and thus it has important consequences for the interpretation of $a$ as an observable. We provide physical examples (also from QFT) where the moment problem for $\{ω(a^n)\}_{n\in\mathbb{N}}$ does not admit a unique solution. To reduce this ambiguity, we consider the moment problem for the sequences $\{ω_b(a^n)\}_{n\in\mathbb{N}}$, being $b\in\mathfrak{A}$ and $ω_b(\cdot):=ω(b^*\cdot b)$. Letting $μ_{ω_b}^{(a)}$ be a solution of the moment problem for the sequence $\{ω_b(a^n)\}_{n\in\mathbb{N}}$, we introduce a consistency relation on the family $\{μ_{ω_{b}}^{(a)}\}_{b\in\mathfrak{A}}$. We prove a 1-1 correspondence between consistent families $\{μ_{ω_{b}}^{(a)}\}_{b\in\mathfrak{A}}$ and positive operator-valued measures (POVM) associated with the symmetric operator $π_ω(a)$. In particular there exists a unique consistent family of $\{μ_{ω_{b}}^{(a)}\}_{b\in\mathfrak{A}}$ if and only if $π_ω(a)$ is maximally symmetric. This result suggests that a better physical understanding of the notion of observable for general $*$-algebras should be based on POVMs rather than projection-valued measure (PVM).

description: The recent observation of ferromagnetic order in two-dimensional (2D) materials has initiated a booming interest in the subject of 2D magnetism. In contrast to bulk materials, 2D materials can only exhibit magnetic order in the presence of magnetic anisotropy. In the present work we have used the Computational 2D Materials Database (C2DB) to search for new ferromagnetic 2D materials using the spinwave gap as a simple descriptor that accounts for the role of magnetic anisotropy. In addition to known compounds we find 12 novel insulating materials that exhibit magnetic order at finite temperatures. For these we evaluate the critical temperatures from classical Monte Carlo simulations of a Heisenberg model with exchange and anisotropy parameters obtained from first principles. Starting from 150 stable ferromagnetic 2D materials we find five candidates that are predicted to have critical temperatures exceeding that of CrI3. We also study the effect of Hubbard corrections in the framework of DFT+U and find that the value of U can have a crucial influence on the prediction of magnetic properties. Our work provides new insight into 2D magnetism and identifies a new set of promising monolayers for experimental investigation.

description: The $Λ$ effect describes a rotation-induced non-diffusive contribution to the Reynolds stress. It is commonly held responsible for maintaining the observed differential rotation of the Sun and other late-type stars. Here the sensitivity of the $Λ$ effect to small-scale magnetic fields and compressibility is studied by means of forced turbulence simulations either with anisotropic forcing in fully periodic cubes or in density-stratified domains with isotropic forcing. Effects of small-scale magnetic fields are studied in cases where the magnetic fields are self-consistently generated by a small-scale dynamo. The results show that small-scale magnetic fields lead to a quenching of the $Λ$ effect which is milder than in cases where also a large-scale field is present. The effect of compressibility on the $Λ$ effect is negligible in the range of Mach numbers from 0.015 to 0.8. Density stratification induces a marked anisotropy in the turbulence and a vertical $Λ$ effect if the forcing scale is roughly two times larger than the density scale height.

Tailings dams quantitative risk prioritization

name: Oboni, Cesar
Publisher: name: The University of British Columbia
Year: 2024

description: This paper assesses the quantitative risks of a portfolio of four dams. It is based on case histories and shows a predictive risk prioritization approach. Dams interdependencies are explicitly considered as interdependent scenarios significantly alter the portfolio risk prioritization. Stability analyses in static and pseudo-static conditions performed by the engineers as well as observations/inspections reports are used as input data. It is shown that the Factor of Safety is not a good discriminant to evaluate safety and thus risks. A documented and published symptom-based simplified probability of failure estimate is used to evaluate the probability of failure of each dam. Dams are benchmarked in relation to the world-wide historical performance as well as using a theoretical dewatered and slurry state tailings dams’ probabilities of failure. Consequences of dams’ breach are quantitatively evaluated using a multidimensional function. Potential for loss of lives is of course included and discussed as well as reputational damages. Indeed, a comprehensive risk metric is the cornerstone in risk communication which is becoming a crucial part of any risk assessment. Enhanced transparency, sensible information, better risk communication will help foster robust Corporate Social Responsibility, Social License to Operate and NI43-101. The risk portfolio is prioritized using various approaches, including a portfolio owner’s risk tolerance threshold. A discussion of the impact on possible prioritizations and decision-making is introduced as well. The paper shows that gut-feeling risk prioritization may be misleading and careful consideration of multiple parameters must be introduced before a sensible and sustainable roadmap can be delivered and communicated to the stakeholders and the public. Finally, a roadmap to portfolio mitigation is defined.

description: Excerpts from the report: The manufacturer-wholesaler margin as used in this study is the difference between the wholesale price of formulated poultry feed and the actual cost of the ingredients. The retail margin is the difference between the wholesale price of the poultry feed and the retail price paid by the farmer for that particular type of feed. The farmer's share is the price received by the farmer for the equivalent ingredients in a particular type of poultry feed, expressed as a percentage of the retail price paid by farmers for that type of feed. All of these price spreads or margins are expressed as percentages and are used to show trends. Formulas used in this study were selected from those published in the 1947 and 1957 editions of the Feed Trade Manual. The recent formulas, both high and low grain, contain more grain than the earlier formulas, as well as ingredients such as vitamins and antibiotics which the earlier formulas did not include. Formulas for both years were used in this study. The objectives of this study are to analyze for poultry feeds (1) the value of price spreads for any one of these formulas as indicators of the actual size of margins--for example, the gross margin for the manufacturer-wholesaler--for a particular type of feed; (2) the value of price spreads for any of the formulas as indicators of trends in margin size; and (3) the factors that have influenced either the actual margin or trends in the margin.

description: The importance of the spin-orbit coupling (SOC) effect in Fe-based superconductors (FeSCs) has recently been under hot debate. Considering the Hund's coupling-induced electronic correlation, the understanding of the role of SOC in FeSCs is not trivial and is still elusive. Here, through a comprehensive study of 77Se and 57Fe nuclear magnetic resonance, a nontrivial SOC effect is revealed in the nematic state of FeSe. First, the orbital-dependent spin susceptibility, determined by the anisotropy of the 57Fe Knight shift, indicates a predominant role from the 3dxy orbital, which suggests the coexistence of local and itinerant spin degrees of freedom (d.o.f.) in the FeSe. Then, we reconfirm that the orbital reconstruction below the nematic transition temperature (Tnem ~ 90 K) happens not only on the 3dxz and 3dyz orbitals but also on the 3dxy orbital, which is beyond a trivial ferro-orbital order picture. Moreover, our results also indicate the development of a coherent coupling between the local and itinerant spin d.o.f. below Tnem, which is ascribed to a Hund's coupling-induced electronic crossover on the 3dxy orbital. Finally, due to a nontrivial SOC effect, sizable in-plane anisotropy of the spin susceptibility emerges in the nematic state, suggesting a spin-orbital-intertwined nematicity rather than simply spin- or orbital-driven nematicity}. The present work not only reveals a nontrivial SOC effect in the nematic state but also sheds light on the mechanism of nematic transition in FeSe.

description: Les inscriptions islamiques du sous-continent indien, dont la collecte et la publication se poursuivent depuis la fin du XVIIIe siècle, n'avaient jusqu'ici pas été étudiées sous une problématique globale. Les deux-cent quatre-vingt seize premières inscriptions arabes et persanes connues de la région (VIIe-XIVe siècles) sont ici réunies, — répertoriées, (ré)éditées, et analysées —, pour documenter la formation et l'histoire des premières sociétés indo-musulmanes et indo-islamiques, prenant en compte les multiples aspects des sources épigraphiques, à la fois textuelles, ou philologiques, et matérielles. Cette thèse montre ainsi dans un premier temps, à travers la répartition chrono-géographique des inscriptions, les divers processus politiques, sociaux et économiques à l'oeuvre dans les différentes phases de pénétration, à la fois commerciales et militaires, de populations musulmanes et islamiques dans les différentes régions du sous-continent indien. Elle étudie ensuite régionalement puis dynastiquement pour le sultanat de Delhi, d'après les textes des inscriptions et notamment les noms et fonctions des personnes mentionnées dans ceux-ci, la composition et les représentations des élites indo-musulmanes, hommes de négoce, de religion, ou d'Etat, militaires. Enfin, elle considère les premières traces d'architectures régionales composites, puis les programmes épigraphiques des principaux monuments patronnés par les sultans de Delhi, en tant que discours "architexturaux", reflets des articulations et "tensions" entre phraséologie islamique et contexte social, politique et religieux.

Secure quantum key distribution with realistic devices

description: In principle, quantum key distribution (QKD) offers information-theoretic security based on the laws of physics. In practice, however, the imperfections of realistic devices might introduce deviations from the idealized models used in security analyses. Can quantum code-breakers successfully hack real systems by exploiting the side channels? Can quantum code-makers design innovative counter-measures to foil quantum code-breakers? This article reviews theoretical and experimental progress in the practical security aspects of quantum code-making and quantum code-breaking. After numerous attempts, researchers now thoroughly understand and are able to manage the practical imperfections. Recent advances, such as the measurement-device-independent protocol, have closed the critical side channels in the physical implementations, paving the way for secure QKD with realistic devices.

description: Drawing upon qualitative methods of semi-structured interviews and observational talk-through interviews, this qualitative dissertation investigates the ways in which graduate students in an online course context experience online instructional videos. A conceptual framework of user experience and multimodality, as well as the framework of sense-making developed by McCarthy and Wright (2004) guided this study and data analysis. The findings of this dissertation have implications for how students are participating in, interacting with, and making sense of online learning environments. Some of the findings of this research include: (a) students do not necessarily experience course videos as discrete elements (or differentiate them with other aspects of the course); (b) the times and contexts in which students view instructional videos shifts (e.g., between home and commuting); (c) student motivations and expectations shape how they approach and orient themselves towards watching online course videos; and (d) multimodal design elements influence students’ meaning-making of online instructional videos. These data findings are all in support of the overarching conclusion of this dissertation, which is that students have significant agency in these online environments, and their meaning-making of online videos may not align with designers’ intentions. This conclusion argues against deterministic views of design. The emerging findings have design implications related to the creation of learning environments in online spaces, such as: (a) fully integrating videos within the broader instructional design of a course; (b) foregrounding the embedded context of instructional videos; and (c) accounting for the shifting times, places, and contexts in which viewers watch instructional videos. This dissertation is situated in the growing field of online education, in particular higher education, where significant money and resources are increasingly dedicated towards the development of online spaces while still much is unknown in relation to the design, experiences, and impact of these online learning environments.

Fingerprints of Classical Instability in Open Quantum Dynamics

description: The dynamics near a hyperbolic point in phase space is modelled by an inverted harmonic oscillator. We investigate the effect of the classical instability on the open quantum dynamics of the oscillator, introduced through the interaction with a thermal bath, using both the survival probability function and the rate of von Neumann entropy increase, for large times. In this parameter range we prove, using influence functional techniques, that the survival probability function decreases exponentially at a rate, K', depending not only on the measure of instability in the model but also on the strength of interaction with the environment. We also show that K' determines the rate of von Neumann entropy increase and that this result is independent of the temperature of the environment. This generalises earlier results which are valid in the limit of vanishing dissipation. The validity of inferring similar rates of survival probability decrease and entropy increase for quantum chaotic systems is also discussed.

description: Kohle ist als Energieträger oder Chemierohstoff nicht universell einsetzbar. Dies ist aber der Fall, wenn die Kohle vergast wird. Das entstehende Gas kann als Brenngas, als Energieträger im Kraftwerk, als Synthesegas für die chemische Industrie und als Reduktionsmittel in der Metallurgie benutzt werden. Störend wirkt sich bei allen Anwendungen der Schwefelgehalt des Gases aus. Bei einem Schwefelgehalt der Kohle von 1% beträgt die Schwefelwasserstoffkonzentration des Gases ca. 0.3 Vol.-%. Eine Entschwefelung des Gases ist mit naßchemischen Verfahren bei tiefen Temperaturen möglich. Wird aber das Gas unmittelbar nach seiner Erzeugung bei hoher Temperatur eingesetzt, so ist eine Heißentschwefelung zweckmäßig, da hierbei die durch Abkühlen und Wiederaufheizen entstehenden Energieverluste sowie die Abscheidung von Spaltungskohlenstoff (bei stark reduzierenden Gasen) vermieden werden. Besonders vorteilhaft ist eine Heißentschwefelung des Gases im kombinierten Gas-Dampfturbinenkraftwerk. Bild 1 zeigt das vereinfachte Schema eines solchen Kraftwerkes. Nach den derzeitigen Projektierungsvorschlägen wird das Gas naßchemisch entschwefelt. Es muß dazu nach dem Austritt aus dem Kohlevergaser in zwei Stufen abgekühlt werden (HT, NT). Das geschieht in einer komplizierten Anlage, die aus mehreren Wärmeaustauschern und weiteren Aggregaten besteht. In der Alternative würde dieses System durch eine einfachere Heißgasentschwefelung ersetzt, in der das Gas auf demselben Temperatur- und Druckniveau, mit dem es aus dem Kohlevergaser austritt, gereinigt würde. Zur Zeit gibt es keine praktikable Technologie für eine Heißentschwefelung.
Slepton Flavour Violation at Colliders

description: In supersymmetric extensions of the Standard Model, the lepton flavour violation (LFV) is closely related to the structure of slepton masses and mixing. Allowing for the most general flavour structure of the slepton sector, consistent with the experimental limits on rare lepton decays, large and distinct signals of LFV at future colliders can be expected. A case study of mixing of second and third generation of sleptons at an e+e- collider is presented and compared to that of tau to mu+gamma rare decay.

description: Consider a finite Abelian group (G,+), with |G|=p^r, p a prime number, and F: G^N -> G^N the cellular automaton given by {F(x)}_n= A x_n + B x_{n+1} for any n in N, where A and B are integers relatively primes to p. We prove that if P is a translation invariant probability measure on G^Z determining a chain with complete connections and summable decay of correlations, then for any w= (w_i:i<0) the Cesaro mean distribution of the time iterates of the automaton with initial distribution P_w --the law P conditioned to w on the left of the origin-- converges to the uniform product measure on G^N. The proof uses a regeneration representation of P.
