Dynamics of organizational climate and job satisfaction in healthcare service practice and research: a protocol for a systematic review

Organizational climate and job satisfaction have been established as fundamental pillars of research and practice in organizational behavior and organizational psychology, inspiring many explanations and operationalizations over time. In most sectors, global trends such as labor shortages, high rates of turnover and absenteeism, the need to increase productivity, and the interest in new work models concur to keep climate and job satisfaction on top of the research agenda. The situation is particularly acute in the healthcare sector, where related factors have the capacity to influence all aspects of care provision, including patient safety and the physical and mental health of care providers. Nevertheless, a gap in knowledge persists regarding climate, job satisfaction, and their relationships in healthcare services. This protocol describes a study that aims to examine the dynamics of climate and job satisfaction in healthcare organizations from the practice and research perspectives. The protocol complies with PRISMA-P. PRISMA will be used to report the results of the study. Databases will be searched for published studies in May 2023, and we expect to complete the study by December 2024. A framework based on a multi-dimensional concept of quality in research will be used to examine the quality of any studies before inclusion. The results will be disseminated in two systematic reviews. We will describe proposed models depicting the dynamics of climate and job satisfaction in healthcare organizations. We will systematize and discuss available evidence regarding the outcomes of climate and job satisfaction in healthcare work environments. We will synthesize information on research designs and methodological options of included studies. We will identify measures of climate and job satisfaction used in healthcare settings, assess their psychometric properties, and appraise the overall quality of underlying studies. Finally, we expect to identify areas in need of further research.
Flow structure and coherence in the wake of a lifting wing with multiscale sinusoidal cut-in trailing edge serrations

This thesis presents an experimental investigation into the wake of a lifting wing with multiscale cut-in trailing edge serrations. More specifically, it looks into how the wake is affected by the serration patterns, both in terms of mean properties and dynamic and spectral information. The flow is investigated by means of particle image velocimetry and hot-wire anemometry to combine the dynamic and spatial strengths of the two experimental techniques. The response of a wing fitted with such serrations and subjected to unsteady inflows is studied by means of lift measurement and hot-wire anemometry in the wake. Cut-in trailing edges are found to generate a strong secondary flow from below the peaks towards the troughs. Such a flow pattern increases the velocity deficit behind the peaks while re-energising the wake behind the troughs, giving rise to span-wise inhomogeneity of the velocity deficit and wake width which persists far downstream. The introduction of cut-in serrations exhibits bluntness that in turn generates vortex shedding that locks into a bent cell structure. The use of multiscale patterns weakens the cell structures which translates into a reduction of vortex shedding intensity as well as a reduction of span-wise correlation at both vortex shedding and low frequencies. The use of an alternative sharp approach offers a compromise that gives less coherence reduction on the edges of the wake but avoids the introduction of a clear vortex shedding signal. Under unsteady inflow conditions, the 2-iteration multiscale pattern provide the strongest overall reduction of coherence. Statistical analysis of lift fluctuations under unsteady and intermittent inflow conditions reveals that the single tone sinusoidal pattern has the strongest reduction of the distribution’s tails. Finally, the multiscale patterns are found to smooth the time-evolution of the lift fluctuations when the wing is submitted to a sinusoidal variation of the flow incidence.
The zeros of the Energy Probability Distribution - A new way to study phase transitions -

We describe an iterative method to study the critical behavior of a system based on the partial knowledge of the complex Fisher zeros set of the partition function. The method is general with advantages over most conventional techniques since it does not need to identify any order parameter a priori. The critical temperature and exponents can be obtained with great precision. To test the method and to show how it works we applied it to the 2D Ising and 6–states Potts models. The strategy can easily be adapted to any model, classical or quantum, once we can build the corresponding energy probability distribution.
New Perspectives on Sex Steroid Hormones Signaling in Cancer-Associated Fibroblasts of Non-Small Cell Lung Cancer

Simple Summary Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Smoking is a major risk factor for NSCLC; however, the incidence of NSCLC among nonsmokers, especially women, is increasing. Therefore, sex hormones are associated with NSCLC progression and their significance has been demonstrated. Cancer-associated fibroblasts, which reside in cancer stroma, are important components that significantly influence cancer progression by interacting with other cells, including cancer cells. We focused on the roles of cancer-associated fibroblasts in hormonal cell–cell interactions in NSCLC and their prospects. Abstract The importance of sex hormones, especially estrogen, in the pathogenesis of non-small-cell lung cancer (NSCLC) has attracted attention due to its high incidence among young adults and nonsmokers, especially those who are female. Cancer-associated fibroblasts (CAFs) reside in the cancer stroma and influence cancer growth, invasion, metastasis, and acquisition of drug resistance through interactions with cancer cells and other microenvironmental components. Hormone-mediated cell–cell interactions are classic cell–cell interactions and well-known phenomena in breast cancer and prostate cancer CAFs. In cancers of other organs, including NSCLC, the effects of CAFs on hormone-receptor expression and hormone production in cancer tissues have been reported; however, there are few such studies. Many more studies have been performed on breast and prostate cancers. Recent advances in technology, particularly single-cell analysis techniques, have led to significant advances in the classification and function of CAFs. However, the importance of sex hormones in cell–cell interactions of CAFs in NSCLC remains unclear. This review summarizes reports on CAFs in NSCLC and sex hormones in cancer and immune cells surrounding CAFs. Furthermore, we discuss the prospects of sex-hormone research involving CAFs in NSCLC.
On the relationship between the matrix operators, vech and vecd

ABSTRACT We introduce a matrix operator, which we call “vecd” operator. This operator stacks up “diagonals” of a symmetric matrix. This operator is more convenient for some statistical analyses than the commonly used “vech” operator. We show an explicit relationship between the vecd and vech operators. Using this relationship, various properties of the vecd operator are derived. As applications of the vecd operator, we derive concise and explicit expressions of the Wald and score tests for equal variances of a multivariate normal distribution and for the diagonality of variance coefficient matrices in a multivariate generalized autoregressive conditional heteroscedastic (GARCH) model, respectively.
The Dodge City Tornadoes on 24 May 2016: Damage Survey, Photogrammetric Analysis Combined with Mobile Polarimetric Radar Data

Polarimetric measurements recorded by a mobile X-band radar are combined with photographs of the Dodge City, Kansas, tornado to quantitatively document the evolving debris cloud. An inner annulus or tube of high radar reflectivity encircled the tornado at low levels. A column of low cross-correlation coefficient ρhv was centered on the funnel cloud during the early stage of the tornado’s life cycle. In addition, two areas of low ρhv were located near the inner annulus of high radar reflectivity and were hypothesized to be regions of high debris loading that have been reproduced in simulations of lofted debris. Another column of low ρhv was a result of strong wind speeds that were progressively lofting small debris and dust as inflow rotated around and within the weak echo notch of the hook echo. A column of negative differential reflectivity ZDR was also centered on the tornado and was hypothesized to result from common debris alignment. The polarimetric structure undergoes a dramatic transition when the debris cloud was prominent and enveloped most of the funnel cloud. The weak echo column (WEC) began to fill at lower levels as large amounts of debris were lofted into the circulation. The axis of minimum ρhv shifted to a radius just beyond the funnel cloud. A column of positive ZDR was collocated with the funnel surrounded by negative ZDR. The negative ZDR and low ρhv within the debris cloud were likely the result of some common debris alignment from wheat stems. The positive ZDR within the funnel signified the presence of a few hydrometeors.
Role-play experience’s effect on students’ 21st century skills propensity

Abstract This study examines the effects of a role-play-based pedagogical method in Finland on the twenty-first century skills propensity among 6th graders (12-year-olds). The approach entails a simulation of a society in a gamified learning environment as part of their formal education. Structural Equation Modeling was employed to analyze the students’ (N = 253) self-reported effects of role-play experience on pre-and post-scores of twenty-first century skills propensity. The results show a statistically significant positive relation between holistic role-play experience and twenty-first century skills propensity, however, closer exploration reveals only few key associations, which perhaps illustrates the complex nature of both role-playing and the framework of twenty-first century learning. However, the broader positive view demonstrates the potential of one meaningful playful day for the skill and attitude development of young students as part of a formal curriculum.
A framework of modeling detector systems for computed tomography simulations

Ultimate development in computed tomography (CT) technology may be a system that can provide images with excellent lesion conspicuity with the patient dose as low as possible. Imaging simulation tools have been cost-effectively used for these developments and will continue. For a more accurate and realistic imaging simulation, the signal and noise propagation through a CT detector system has been modeled in this study using the cascaded linear-systems theory. The simulation results are validated in comparisons with the measured results using a laboratory flat-panel micro-CT system. Although the image noise obtained from the simulations at higher exposures is slightly smaller than that obtained from the measurements, the difference between them is reasonably acceptable. According to the simulation results for various exposure levels and additive electronic noise levels, x-ray quantum noise is more dominant than the additive electronic noise. The framework of modeling a CT detector system suggested in this study will be helpful for the development of an accurate and realistic projection simulation model.
Broadband absorption enhancement in amorphous Si solar cells using metal gratings and surface texturing

The efficiencies of thin film amorphous silicon (a-Si) solar cells are restricted by the small thickness required for efficient carrier collection. This thickness limitations result in poor light absorption. In this work, broadband absorption enhancement is theoretically achieved in a-Si solar cells by using nanostructured back electrode along with surface texturing. The back electrode is formed of Au nanogratings and the surface texturing consists of Si nanocones. The results were then compared to random texturing surfaces. Three dimensional finite difference time domain (FDTD) simulations are used to design and optimize the structure. The Au nanogratings achieved absorption enhancement in the long wavelengths due to sunlight coupling to surface plasmon polaritons (SPP) modes. High absorption enhancement was achieved at short wavelengths due to the decreased reflection and enhanced scattering inside the a-Si absorbing layer. Optimizations have been performed to obtain the optimal geometrical parameters for both the nanogratings and the periodic texturing. In addition, an enhancement factor (i.e. absorbed power in nanostructured device/absorbed power in reference device) was calculated to evaluate the enhancement obtained due to the incorporation of each nanostructure.
A Transdisciplinary Analysis of Domestic Violence Homicides in Harris County, Texas (2016-2020)

A transdisciplinary, community-engaged approach enables researchers to connect knowledge generation with domestic violence homicide prevention. This case study utilizes medical examiner data from Harris County, Texas (2016–2020, n = 2,517) to identify and examine correlates of domestic violence homicides. The research team identified more than double the number of domestic violence homicides than had been flagged in the original data. Geospatial analysis identified unequal distribution of homicide across communities and significant gender-based disparities in domestic violence homicides. Transdisciplinary approaches can be used to accurately identify domestic violence homicides and provide a foundation to develop multi-level interventions.
Euclidean Submanifolds via Tangential Components of Their Position Vector Fields

The position vector field is the most elementary and natural geometric object on a Euclidean submanifold. The position vector field plays important roles in physics, in particular in mechanics. For instance, in any equation of motion, the position vector x (t) is usually the most sought-after quantity because the position vector field defines the motion of a particle (i.e., a point mass): its location relative to a given coordinate system at some time variable t. This article is a survey article. The purpose of this article is to survey recent results of Euclidean submanifolds associated with the tangential components of their position vector fields. In the last section, we present some interactions between torqued vector fields and Ricci solitons.
Elegant Laguerre–Gaussian beams—formulation of exact vector solution

In photonic applications of optical beams, their transverse cross-section should be often narrow, with a diameter in their waist of the order of one wavelength or even less. Within this range, the paraxial approximation of beam fields is not valid and standard corrections by field expansions with respect to a small parameter are not efficient as well. Thus, still there is a need for more accurate beam field description. In this report, an exact vector solution for free-space propagation is given in terms of elegant Laguerre–Gaussian beams. The analysis starts from the known paraxial field approximation and next, through bidirectional field transformation and application of a Hertz potential leads to an exact vector solution. The role of the paraxial solution in construction of the exact solution is elucidated. The method works well not only in cases of free-space propagation but also in description of beam interactions with planar interfaces and multilayers.
Identifying Biomarkers of Spinal Muscular Atrophy for Further Development

Background: Spinal muscular atrophy (SMA) is caused by bi-allelic, recessive mutations of the survival motor neuron 1 (SMN1) gene and reduced expression levels of the survival motor neuron (SMN) protein. Degeneration of alpha motor neurons in the spinal cord causes progressive skeletal muscle weakness. The wide range of disease severities, variable rates of decline, and heterogenous clinical responses to approved disease-modifying treatment remain poorly understood and limit the ability to optimize treatment for patients. Validation of a reliable biomarker(s) with the potential to support early diagnosis, inform disease prognosis and therapeutic suitability, and/or confirm response to treatment(s) represents a significant unmet need in SMA. Objectives: The SMA Multidisciplinary Biomarkers Working Group, comprising 11 experts in a variety of relevant fields, sought to determine the most promising candidate biomarker currently available, determine key knowledge gaps, and recommend next steps toward validating that biomarker for SMA. Methods: The Working Group engaged in a modified Delphi process to answer questions about candidate SMA biomarkers. Members participated in six rounds of reiterative surveys that were designed to build upon previous discussions. Results: The Working Group reached a consensus that neurofilament (NF) is the candidate biomarker best poised for further development. Several important knowledge gaps were identified, and the next steps toward filling these gaps were proposed. Conclusions: NF is a promising SMA biomarker with the potential for prognostic, predictive, and pharmacodynamic capabilities. The Working Group has identified needed information to continue efforts toward the validation of NF as a biomarker for SMA.
NUMERICAL SIMULATION OF MAGNETIC FLUID FLOWS BY A FINITE VOLUME METHOD

Pressure-driven flow of a magnetic fluid in cylindrical tubes is investigated using numerical simulations. The simulations are based on a Finite Volume Method adapted for incorporating a magnetization evolution equation. The magnetostatic limit of the Maxwell's equations is treated in terms of a Poisson equation numerically integrated. Suitable boundary conditions for velocity, magnetization and field intensity on the pipe wall are described. Results are obtained for velocity and magnetization profiles under several conditions of the identified physical parameters of the flow. The simulations are verified by comparison between numerical results and asymptotic theory, and they show good agreement.
Epidemiology of Helicobacter pylori Resistance to Antibiotics (A Narrative Review)

Helicobacter pylori (H. pylori) is the most common bacterial infection worldwide and one of the main etiological factors of chronic gastritis, peptic ulcer disease, and stomach neoplasms. The mass application of antibiotics without testing, especially during the last years of the pandemic of SARS-CoV-2, could lead to a dramatic increase in antibiotic resistance and reduced effectiveness of eradication regimens for H. pylori infection. The epidemiology of H. pylori resistance to antibiotics still has unclear mechanisms. Antibiotic policy should be intensified to optimize treatment, and regular monitoring of resistance of H. pylori in different geographical regions should be conducted. Individualized treatment according to susceptibility testing is strongly advisable, and the best treatment regimens should be selected. The mutations in the genes encoding the antibiotic target protein are significant risk factors for H. pylori resistance. Iatrogenic errors in diagnosis and prescribing treatment for the failure of H. pylori eradication are other important risk factors. The low level of awareness and compliance with the correct treatment influence the rate of H. pylori resistance. Epidemiological surveillance of antibiotic resistance and the adoption of new treatment strategies are needed. The discovery of an efficient vaccine against H. pylori could reduce the pressure of the world’s growing antibiotic resistance.
Police notification by Black victims of violent crime: the role of victim gender and victim-offender relationship

Abstract Despite widespread distrust of police among Black Americans, research indicates that Black crime victims are more likely to call the police than other demographic groups. Using National Crime Victimization Survey data from 1994–2018, I employ logistic regression and compare the average marginal effects of victim race and gender on probabilities of reporting to police. Of four race-sex categories (non-Black and Black male and female victims), I find that Black women are most likely to report and Black men are least likely. But when the offender is a romantic partner, family member, or other household member, Black victims of either gender are more likely to report. Evidence points to the importance of victim gender and victim-offender relationship in understanding racial differences in crime reporting.
The effect of homophony avoidance in voicing

It has been long acknowledged that the production and perception of speech are affected by the presence or absence of higher levels of linguistic information, too. The recoverability of meaning heavily relies on semantic context (Ganong 1980); similarly, the precision of articulation is inversely proportional to the presence of semantic information (Goldrick et al. 2013; Kitahara et al. 2019). Diachronic phonological processes, for example, are often reported to seek homophony avoidance (see, e.g., Silverman 2012). The question arises whether homophony avoidance is actively present in synchronic language use, too, and how (if at all) it interacts with phonological contrast maintenance or neutralisation. A number of studies demonstrate that laryngeal processes previously considered to be neutralising (e.g., word-final devoicing, voicing assimilation) are not completely neutralizing phonetically. An underlyingly voiced obstruent often contains more phonation in devoicing contexts than an underlyingly voiceless obstruent, or if this is not the case, other phonetic features like the length of the preceding vowel, or the vowel/consonant duration ratio are systematically different, thereby maintaining the underlying laryngeal contrast (Bárkányi and G. Kiss 2019 provide an overview in Hungarian of this). The present study seeks to explore to what extent a particular lexical factor, homophony avoidance, i.e., whether or not a word forms a minimal pair with another word in the lexicon (“minimal pairhood”), affects the realisation of the primary laryngeal feature, the amount of phonation, in the word-final alveolar stops /t/ and /d/ and the fricatives /s/ and /z/ in potentially neutralising and nonneutralising contexts in the speech of Hungarian native speakers. To this end, acoustic experiments were carried out with test words ending in these obstruents in minimal pairs and non-minimal pairs that were placed in various phonetic environments.
