Nurses’ perceptions of person-centered care in inpatient care units in Saudi Arabia
Creators: name: Alamrani, Masheal Hasan H.
Publisher: name: No Publisher Supplied
Year: 2024

description: Problems previously identified in the implementation of person-centered care in Saudi Arabia include communication barriers, work environment factors, and cultural discordance between patients and nurses. Some have questioned whether Western person-centered care concepts are even applicable in a non-Western setting. In a nation where the majority of nurses are international migrant workers, better understanding is needed of what person-centered care means to nurses and how they manage to enact it in practice. This qualitative descriptive study aimed to explore nurse perceptions of person-centered care in inpatient units in Saudi Arabia and identify what nurses regard as facilitators and barriers to person-centered care. One-on-one semi-structured interviews were conducted via Zoom with 21 nurses working in two hospitals in Riyadh City, Saudi Arabia. One was a Magnet® hospital. Interviewees included both Saudi-born and expatriate nurses. Qualitative analysis was then conducted recursively in a process combining both inductive and deductive elements. Regardless of cultural background and place of work, nurses described extensive efforts to provide individualized, empathic, developmentally appropriate, culturally sensitive care enabling patients and families to access information and participate in decisions. Perceptions of person-centered care aligned with established definitions. However, nurses did not separate descriptions of care from challenges encountered at the patient, organizational, and regional levels, including staffing and supplies shortages, gaps in regional care coordination, inadequate translation services, cultural beliefs limiting certain nurse-patient interactions, hostility toward foreign-born staff, and occasional violence. Differences were found between the Magnet® and the non-Magnet® setting. Nurses reported confronting these challenges through creativity, patience, knowledge, time, teamwork, and emotional self-regulation. The findings suggest that nurses’ understanding of person-centered care should be characterized more accurately as "situation"-responsive care – a process of doing one’s best to achieve professional nursing values while contending with the difficult realities that define the context of care. The results of this research can help inform Saudi healthcare managers and policymakers to design programs that will limit the challenges nurses face as they endeavor to provide respectful, attentive, individualized, and responsive care.

description: We prove that kernels of analytic functions of kind $H_{h,β}(t)=\sum\limits_{k=1}^{\infty}\frac{1}{\cosh kh}\cos\Big(kt-\frac{βπ}{2}\Big)$, $h>0$, ${β\in\mathbb{R}}$, satisfies Kushpel's condition $C_{y,2n}$ beginning with some number $n_h$ which is explicitly expressed by parameter $h$ of smoothness of the kernel. As a consequence, for all $n\geqslant n_h$ we obtain lower bounds for Kolmogorov widths $d_{2n}$ of functional classes that are representable as convolutions of kernel $H_{h,β}$ with functions $φ\perp1$, which belong to the unit ball in the space $L_{\infty}$, in the space $C$. The obtained estimates coincide with the best uniform approximations by trigonometric polynomials for these classes. As a result, we obtain exact values for widths of mentioned classes of convolutions. Also for all $n\geqslant n_h$ we obtain exact values for Kolmogorov widths $d_{2n-1}$ of classes of convolutions of functions $φ\perp1$, which belong to the unit ball in the space $L_1$, with kernel $H_{h,β}$ in the space $L_1$.

title: A certain tendency?: style and meaning in the British New Wave
Creators: name: Taylor, Barnaby Falcon
Publisher: name: University of Kent
Year: 2022

description: Conventional approaches to the British New Wave tend to place their greatest emphasis upon viewing the films as a series, stressing the similarities they share with one other and using the fact of these similarities to include them in broader debates about class, gender and/or ideology. Dissatisfied with this tendency, my intention is to take an alternative approach and consider each of the films individually. This is not to deny that the similarities between these films don’t exist. Nevertheless, for the sake of revivifying the study of British cinema, I see little methodological sense in being content merely to reproduce existing critical discussions. Instead, I intend to define my own critical position and demonstrate that we might fruitfully consider the detail of an individual film without having to continually reemphasise the similarities that might be shared with other films. In each case, I will show that a re-distribution of critical emphasis will not only allow my discussions of the films to be based around questions of their style and meaning but will also allow the problematic relationship between these films and the question of realism to be reconsidered. There is an important distinction to make here. I’m not suggesting that social realist conventions weren’t utilised by the films. Nevertheless, a repeated emphasis upon the use of these conventions leading to a flawed series of films has become little more than an effective means of closing down discussion. Surely, there is something else that we might start to say about these films? To this end, my approach will be based upon the idea of difference. Though there might be inevitable or unavoidable similarities between Room at the Top and A Kind of Loving, the main focus of my investigation will be upon the differences that can be found at the level of their respective style and meaning.
Ages of Type Ia Supernovae Over Cosmic Time

description: We derive empirical models for galaxy mass assembly histories, and convolve these with theoretical delay time distribution (DTD) models for Type Ia supernovae (SNe Ia) to derive the distribution of progenitor ages for all SNe Ia occurring at a given epoch of cosmic time. In actively star-forming galaxies, the progression of the star formation rate is shallower than a $t^{-1}$ SN Ia DTD, so mean SN Ia ages peak at the DTD peak in all star-forming galaxies at all epochs of cosmic history. In passive galaxies which have ceased star formation through some quenching process, the SN Ia age distribution peaks at the quenching epoch, which in passive galaxies evolves in redshift to track the past epoch of major star formation. Our models reproduce the SN Ia rate evolution in redshift, the relationship between SN Ia stretch and host mass, and the distribution of SN Ia host masses in a manner qualitatively consistent with observations. Our model naturally predicts that low-mass galaxies tend to be actively star-forming while massive galaxies are generally passive, consistent with observations of galaxy "downsizing". Consequently, the mean ages of SNe Ia undergo a sharp transition from young ages at low host mass to old ages at high host mass, qualitatively similar to the transition of mean SN Ia Hubble residuals with host mass. The age discrepancy evolves with redshift in a manner currently not accounted for in SN Ia cosmology analyses. We thus suggest that SNe Ia selected only from actively star-forming galaxies will yield the most cosmologically uniform sample, due to the homogeneity of young SN Ia progenitor ages at all cosmological epochs.

Harmful competition in the insurance markets

Adverse selection

description: There is a general presumption that competition is a good thing. In this paper we show that competition in the insurance markets can be bad and that adverse selection is in general worse under competition than under monopoly. The reason is that monopoly can exploit its market power to relax incentive constraints by cross-subsidization between di erent risk types. Cream-skimming behavior, on the contrary, prevents competitive rms from using implicit transfers. In e ect monopoly is shown to provide better coverage to those buying insurance but at the cost of limiting participation to insurance. Performing simulation for di erent distributions of risk, we nd that monopoly in general performs (much) better than competition in terms of the realization of the gains from trade across all traders in equilibrium. However, most of the surplus is retained by the rm and, as a result, most individuals prefer competitive markets notwithstanding their performance is generally poorer than monopoly.

description: Η ανάγκη για μείωση του κόστους και αύξηση της παραγωγικότητας στην αεροπορική βιομηχανία, οδηγεί στην είσοδο νέων παραγωγικών μεθόδων, όπως οι συγκολλήσεις. Μέχρι σήμερα οι αναλυτικές μέθοδοι που χρησιμοποιούνται για τον υπολογισμό ανοχής στη βλάβη των συγκολλήσεων, δεν λαμβάνουν υπόψη τις μεταβολές της μικροδομής στη ΘΕΖ. Οι μεταβολές αυτές συνοδεύονται με υποβάθμιση των μηχανικών ιδιοτήτων του υλικού. Σε αυτή την εργασία έγινε μια πρώτη προσπάθεια προσομοίωσης της μεταβολής μικροσκληρότητας στη ΘΕΖ. Έγινε μέτρηση του προφίλ μικροσκληρότητας συγκολλημένου ελάσματος αλουμινίου 6013-Τ6, πάχους 1.6mm, με την μέθοδο TIG. Στη συνέχεια, με ισόθερμες θερμικές κατεργασίες, σε δοκίμια ίδιου κράματος αναπαρήχθησαν οι τιμές μικροσκληρότητας της ΘΕΖ. Οι συνθήκες των ισόθερμων θερμικών κατεργασιών επιλέχθηκαν με βάση τα αποτελέσματα του προγράμματος Mathematica, με το οποίο υπολογίστηκε η θερμοκρασία των ελασμάτων κατά τη διάρκεια της συγκόλλησης. Οι συνδυασμοί θερμοκρασίας - χρόνου θερμικής κατεργασίας αντιστοιχήθηκαν με τις μετρούμενες τιμές μικροσκληρότητας σε συγκεκριμένα σημεία της ΘΕΖ. Το βασικότερο συμπέρασμα της παρούσας διατριβής είναι ότι με ισόθερμες θερμικές κατεργασίες είναι δυνατόν να γίνει προσομοίωση της μεταβολής της μικροδομής στη ΘΕΖ. Αυτό στην πράξη σημαίνει ότι είναι εφικτό να κατασκευαστούν δοκίμια εύρεσης ρυθμού εξέλιξης ρωγμής κόπωσης (fatigue crack growth) για να μελετηθεί πειραματικά η συμπεριφορά της ανοχής σε βλάβη (Damage Tolerance behavior) συγκολλητών κατασκευών.

description: The asymmetry in the forward region production cross section of D^\pm is calculated using the heavy-quark recombination mechanism for pp collisions at 7 TeV. By suitable choices of four non-perturbative parameters, our calculated results can reproduce those obtained at LHCb. We find A_p ~ -1% when integrated over 2.0 GeV < p_T < 18 GeV and 2.2< eta <4.75, which agrees with A_p=-0.96\pm0.26\pm0.18% as measured by LHCb. Furthermore, the calculated distributions in eta and p_T agree reasonably well with those obtained at LHCb.

description: We report a photoemission and x-ray absorption study on Au1-xPtxTe2 (x = 0 and 0.35) triangular lattice in which superconductivity is induced by Pt substitution for Au. Au 4f and Te 3d core-level spectra of AuTe2 suggests a valence state of Au2+(Te2)2-, which is consistent with its distorted crystal structure with Te-Te dimers and compressed AuTe6 otahedra. On the other hand, valence-band photoemission spectra and pre-edge peaks of Te 3d absorption edge indicate that Au 5d bands are almost fully occupied and that Te 5p holes govern the transport properties and the lattice distortion. The two apparently conflicting pictures can be reconciled by strong Au 5d/Au 6s-Te 5p hybridization. Absence of a core-level energy shift with Pt substitution is inconsistent with the simple rigid band picture for hole doping. The Au 4f core-level spectrum gets slightly narrow with Pt substitution, indicating that the small Au 5d charge modulation in distorted AuTe2 is partially suppressed.

description: Hot Jupiters may have formed in situ, or been delivered to their observed short periods through one of two categories of migration mechanisms: disk migration or high-eccentricity migration. If hot Jupiters were delivered by high-eccentricity migration, we would expect to observe some "super-eccentric" Jupiters in the process of migrating. We update a prediction for the number of super-eccentric Jupiters we would expect to observe in the Kepler sample if all hot Jupiters migrated through high-eccentricity migration and estimate the true number observed by Kepler. We find that the observations fail to match the prediction from high-eccentricity migration with 94.3% confidence and show that high-eccentricity migration can account for at most ~62% of the hot Jupiters discovered by Kepler.

description: Pathological changes in the oral cavity contribute to the development of various dental diseases. The increase in the incidence of periodontal diseases and dental caries is the reason for the increased demand of patients with diabetes for dental care. According to R.I. Runge (2014), 53.7% of patients with diabetes need orthopedic dental treatment. Dentures, even for patients without general somatic pathologies, have a number of side effects. Removable dentures have the greatest impact on the organs and tissues of the oral cavity. Violation of the microcirculation of the tissues of the prosthetic bed, the function of salivation and factors of local immunity of the oral cavity contributes to the formation of dental plaque, which entails a change in the microflora of the oral cavity, both quantitatively and qualitatively.

description: We describe an efficient and parsimonious matrix-based theory for studying the ensemble behavior of self-propellers and active swimmers, such as nanomotors or motile bacteria, that are typically studied by differential-equation-based Langevin or Fokker-Planck formalisms. The kinematic effects for elementary processes of motion are incorporated into a matrix, called the "kinematrix", from which we immediately obtain correlators and the mean and variance of angular and position variables (and thus effective diffusivity) by simple matrix algebra. The kinematrix formalism enables us recast the behaviors of a diverse range of self-propellers into a unified form, revealing universalities in their ensemble behavior in terms of new emergent time scales. Active fluctuations and hydrodynamic interactions can be expressed as an additive composition of separate self-propellers.

description: The existence of second-order structural phase transition in the SnS at a pressure of 16 GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) with the help of the ABINIT software package. The abrupt change in volume compression with unit cell volume continuous change of the crystal is the clear evidence of the second-order phase transition. It is shown that the phase transition is caused by the softening of the low-frequency fully symmetric interlayer mode with increasing pressure. As a result, displacement type phase transition (PT) take place with the change of translational symmetry of the crystal from the simple orthorhombic to the base-centered orthorhombic (Pcmn to Cmcm).

description: Hydrocarbon prospect risking is a critical application in geophysics predicting well outcomes from a variety of data including geological, geophysical, and other information modalities. Traditional routines require interpreters to go through a long process to arrive at the probability of success of specific outcomes. AI has the capability to automate the process but its adoption has been limited thus far owing to a lack of transparency in the way complicated, black box models generate decisions. We demonstrate how LIME -- a model-agnostic explanation technique -- can be used to inject trust in model decisions by uncovering the model's reasoning process for individual predictions. It generates these explanations by fitting interpretable models in the local neighborhood of specific datapoints being queried. On a dataset of well outcomes and corresponding geophysical attribute data, we show how LIME can induce trust in model's decisions by revealing the decision-making process to be aligned to domain knowledge. Further, it has the potential to debug mispredictions made due to anomalous patterns in the data or faulty training datasets.

description: Innovation plays a crucial role in the development and the sustainability of the economy. Regardless its importance and the numerous national and international programs to promote and support innovation, it still remains an ad-hoc process based on hand-shaking and brainstorming. It is expected that Computer Aided Innovation (CAI) will have an impact similar to the one that Computer Aided Design and Computer Aided Engineering had to Manufacturing. In thesis we investigate the notion of CAI and try to collect the essential elements that might lead to a systematic approach for innovation. Specifically we first review the available theories and frameworks that have the potential to provide the necessary background for future CAI systems. Specifically we consider TRIZ, ARIZ, QFD, SIX SIGMA and few others which they surely have a common objective but so far they seem to be unrelated from most other aspects. We compare them and try to identify their conceptual similarities and their common components at the semantic level. Furthermore, we have systematically collected the available software systems for Innovation and interrelated them to our theoretical review. We conclude by proposing a semantic based software platform for CAI and investigate the critical issues concerning its implementation

description: Deep learning can extract rich data representations if provided sufficient quantities of labeled training data. For many tasks however, annotating data has significant costs in terms of time and money, owing to the high standards of subject matter expertise required, for example in medical and geophysical image interpretation tasks. Active Learning can identify the most informative training examples for the interpreter to train, leading to higher efficiency. We propose an Active learning method based on jointly learning representations for supervised and unsupervised tasks. The learned manifold structure is later utilized to identify informative training samples most dissimilar from the learned manifold from the error profiles on the unsupervised task. We verify the efficiency of the proposed method on a seismic facies segmentation dataset from the Netherlands F3 block survey, significantly outperforming contemporary methods to achieve the highest mean Intersection-Over-Union value of 0.773.

description: Edema is a common symptom of kidney disease, and quantitative measurement of edema is desired. This paper presents a method to estimate the degree of edema from facial images taken before and after dialysis of renal failure patients. As tasks to estimate the degree of edema, we perform pre- and post-dialysis classification and body weight prediction. We develop a multi-patient pre-training framework for acquiring knowledge of edema and transfer the pre-trained model to a model for each patient. For effective pre-training, we propose a novel contrastive representation learning, called weight-aware supervised momentum contrast (WeightSupMoCo). WeightSupMoCo aims to make feature representations of facial images closer in similarity of patient weight when the pre- and post-dialysis labels are the same. Experimental results show that our pre-training approach improves the accuracy of pre- and post-dialysis classification by 15.1% and reduces the mean absolute error of weight prediction by 0.243 kg compared with training from scratch. The proposed method accurately estimate the degree of edema from facial images; our edema estimation system could thus be beneficial to dialysis patients.

description: The aim of this paper is to determinate the fundamental parameters of six exoplanet host (EH) stars and their planets. While techniques for detecting exoplanets yield properties of the planet only as a function of the properties of the host star, hence, we must accurately determine parameters of EH stars at first. For this reason, we constructed a grid of stellar models including diffusion and rotation-induced extra-mixing with given ranges of input parameters (i.e. mass, metallicity, and initial rotation rate). In addition to the commonly used observational constraints such as the effective temperature T_{eff}, luminosity L and metallicity [Fe/H], we added two observational constraints, the lithium abundance log N (Li) and the rotational period P_{rot}. These two additional observed parameters can make further constrains on the model due to their correlations with mass, age and other stellar properties. Hence, our estimations of fundamental parameters for these EH stars and their planets are with higher precision than previous works. Therefore, the combination of rotational period and lithium help us to obtain more accurate parameters for stars, leading to an improvement of the knowledge of the physical state about the EH stars and their planets.

A reverse genetic and kinetic investigation of the reductive-oxidative iron uptake pathway in Thalassiosira pseudonana
Creators: name: Bornhorst, Robert Henry Bisner
Publisher: name: No Publisher Supplied
Year: 2024

description: Iron is an essential cofactor to the photosynthetic processes of marinephytoplankton and one of their most commonly limiting resources. In chapter 1, we compare the proteomes of steady-state Fe limited Thalassiosira pseudonana and Phaeocystis globosa, two coastal algae with substantially different tolerances for open ocean Fe levels. Different Fe uptake proteins were upregulated in these two species (phytotransferrin in P. globosa, ferric permeases in T. pseudonana). These findings were then correlated with a series of kinetic Fe uptake experiments assessing phytotransferrin mediated uptake in both organisms. We conclude that unlike most marine phytoplankton, T.pseudonana does not engage in phytotransferrin mediated Fe uptake, consistent with its recent freshwater ancestry. One model for iron uptake in diatoms requires a ferric reduction step at the cell surface. In yeast, a similar reduction step is part of the reductive-oxidative Fe uptake pathway through a ferric reductase protein (FRE). A ferroxidase-ferric permease (FET3/FTR) complex then subsequently binds, oxidizes, and transports Fe(III). FET and FTR are co-obligate partners, and the yeast permease cannot access Fe(III) directly from the dissolved milieu. Homologous proteins are predicted in the genome of model diatom T. pseudonana, including two FTRs but only one FET. In chapter two, we investigated the role of the putative ferric permeases (FTR1, FTR2) and the ferroxidase (FET) using reverse genetics. FTR transcriptional knock-down clones grew slower under steady-state iron limiting conditions. GFP chimeras of both proteins, under native promotion, were localized at the cell surface and upregulated in limiting Fe. FET knock-out mutants had no phenotypic difference with wild-type when growing in Fe limiting conditions. We hypothesize that one or both permeases engages in direct uptake of Fe3+ independent of a ferroxidase.

description: Preferential trade agreements (PTAs) are generally understood to promote political cooperation between members. I argue that institutional exclusion can damage political cooperation between members and non-members. Preferential trade agreements reflect strategic considerations, enabling countries to promote new trade norms, strengthen diplomatic networks, and redirect commercial flows to allies. Excluded countries are denied these benefits and may possibly be targeted by members. Thus, excluding PTAs may be perceived as threats. The record of the Trans-Pacific Partnership illustrates the theory. Statistical analysis of the near-universe of PTAs and countries’ voting affinities in the United Nations General Assembly supports the argument.

description: Instance segmentation in videos, which aims to segment and track multiple objects in video frames, has garnered a flurry of research attention in recent years. In this paper, we present a novel weakly supervised framework with \textbf{S}patio-\textbf{T}emporal \textbf{C}ollaboration for instance \textbf{Seg}mentation in videos, namely \textbf{STC-Seg}. Concretely, STC-Seg demonstrates four contributions. First, we leverage the complementary representations from unsupervised depth estimation and optical flow to produce effective pseudo-labels for training deep networks and predicting high-quality instance masks. Second, to enhance the mask generation, we devise a puzzle loss, which enables end-to-end training using box-level annotations. Third, our tracking module jointly utilizes bounding-box diagonal points with spatio-temporal discrepancy to model movements, which largely improves the robustness to different object appearances. Finally, our framework is flexible and enables image-level instance segmentation methods to operate the video-level task. We conduct an extensive set of experiments on the KITTI MOTS and YT-VIS datasets. Experimental results demonstrate that our method achieves strong performance and even outperforms fully supervised TrackR-CNN and MaskTrack R-CNN. We believe that STC-Seg can be a valuable addition to the community, as it reflects the tip of an iceberg about the innovative opportunities in the weakly supervised paradigm for instance segmentation in videos.

description: FOCCoS, Fiber Optical Cable and Connector System, has the main function of capturing the direct light from the focal plane of Subaru Telescope using optical fibers, each one with a microlens in its tip, and conducting this light through a route containing connectors to a set of four spectrographs. The optical fiber cable is divided in 3 different segments called Cable A, Cable B and Cable C. Multi-fibers connectors assure precise connection among all optical fibers of the segments, providing flexibility for instrument changes. To assure strong and accurate connection, these sets are arranged inside two types of assemblies: the Tower Connector, for connection between Cable C and Cable B; and the Gang Connector, for connection between Cable B and Cable A. Throughput tests were made to evaluate the efficiency of the connections. A lifetime test connection is in progress. Cable C is installed inside the PFI, Prime Focus Instrument, where each fiber tip with a microlens is bonded to the end of the shaft of a 2-stage piezo-electric rotatory motor positioner; this assembly allows each fiber to be placed anywhere within its patrol region, which is 9.5mm diameter.. Each positioner uses a fiber arm to support the ferrule, the microlens, and the optical fiber. 2400 of these assemblies are arranged on a motor bench plate in a hexagonal-closed-packed disposition.
