Covid in the nursing homes: the US experience

The death toll in nursing homes accounted for almost 30 per cent of total Covid-19 deaths in the US during 2020. We examine the course of the pandemic in nursing homes focusing especially on whether nursing homes could have been better shielded. Across all nursing homes the key predictor of infections and deaths was community spread, i.e. a factor outside of the control of nursing homes. We find that higher-quality nursing homes, as measured by the CMS Five-Star Rating system, were not better able to protect their residents. Policy failures from the CDC and FDA, especially in the early stages of the pandemic, created extended waiting times for Covid-19 tests and slowed attempts to isolate infectious residents. But once infections were widespread, testing would have had to have been much greater to have had an appreciable effect on nursing home deaths. We find, however, that starting vaccinations just 5 weeks earlier could have saved in the order of 14,000 lives and starting them ten weeks earlier could have saved 40,000 lives.
RelationshipsRelationships 11 Among Applications of Tacit Knowledge and Among Applications of Tacit Knowledge and Transformational/Transactional Leader Styles: An Exploratory Transformational/Transactional Leader Styles: An Exploratory Comparison of the MLQ and TKML Comparison of the MLQ and TKML

Purpose: The purpose of this research is to examine intercorrelational relations among the self-report behavioral construct Multifactor Leadership Questionnaire (MLQ) 5X transformational and transactional subscales and the Tacit Knowledge for Military Leaders Inventory (TKML) leader-level specific situational judgment test scenarios. Design/methodology/approach: Two leadership measures, the behavioral construct Multifactor Leadership Questionnaire (MLQ) and the cognitive construct Tacit Knowledge for Military Leaders Inventory (TKML) assess different aspects of how a leader functions and were administered to 125 active U.S. Army officers representing three leader levels: platoon, company, and battalion. We examine the intercorrelational relationship between these two measures. Findings: Results show a correlational pattern that contours the evolution of a leader’s skills (from novice platoon leader to expert battalion leader), with the strongest correlation at the higher leader levels. Research limitations: The decision to restrict the number of TKML scenarios provided to respondents and to administer the MLQ and TKML to the same sample. Practical implications: Pairing the MLQ and TKML makes use of self-reported leader behaviors with maximal assessment scales that directly assess respondents’ understanding of what the best approaches to good leadership are. Social implications: Response patterns from both measures permits direct counseling on the misconceptions about leadership to create better leaders. Originality/value: No previous research has examined correlative relations among the scales/subscales of the MLQ and TKML.
Sheep Grazing Effect on Dryland Soil Carbon and Nitrogen in the Wheat-Fallow System

Weed control by sheep grazing during fallow periods in the dryland wheat-fallow system may influence soil C and N levels. The effects of fallow management for weed control and soil water conservation [sheep grazing (grazing), herbicide application (chemical), and tillage (mechanical)] and cropping sequence [continuous spring wheat (CSW), spring wheat-fallow (SW-F), and winter wheatfallow (WW-F)] on wheat biomass (stems + leaves) yield and soil organic C (SOC) and total N (STN) at the 0-120 cm depth was evaluated from 2004 to 2008 in western Montana. Annualized wheat biomass yield was greater in CSW than in SW-F and WW-F from 2004 to 2006 but varied among fallow management practices from 2004 to 2008. In 2008, SOC at 10-30, 30-60, 90-120, and 0-120 cm was greater in the mechanical than in the chemical or grazing treatment in CSW. In SW-F, SOC at 10-30, 30-60, and 0-120 cm was greater in the chemical than in the mechanical or grazing treatment. Similarly, STN at 0-5 cm was greater in the chemical and mechanical than in the grazing treatment but at 30-60 cm was greater in the grazing than in the chemical treatment in CSW. Reduced amount of wheat residue returned to the soil due to consumption by sheep during grazing probably reduced SOC and STN at the surface and subsurface layers compared with tillage and herbicide application. For sustaining wheat yields and soil organic matter, reduced tillage with continuous cropping and less intensive sheep grazing may be needed to increase the amount of residue returned to the soil.
Sugarcane Growing and The Livelihoods of Small-Scale Farmers in Jinja District, Uganda

This study focused on establishing the relationship between sugarcane growing and the livelihood of small-scale farmers in the Jinja District. The study adopted a descriptive research design. The target population of this study was sugarcane growing households' heads and Village Chairpersons of the sugarcane out-growers association. The study employed purposive and simple random sampling techniques—a sample size of 42 respondents from a population of 362 small-scale farmers. The data collection methods included questionnaires, interviewing, focus group discussions, and observation. The study generated both qualitative and quantitative data. The data collected was analyzed by computing percentages, while qualitative data was analyzed by coding and establishing common themes. This study revealed that although women are fully involved in sugarcane growing, ownership of farms is dominated by men. The dominant age group among the sugarcane farmers is between 30 to 60 years, with mainly primary education graduates. The average farm size was 3 acres, and most farmland was devoted to growing sugarcane. There are some positive benefits from sugar growing, though many challenges have been identified. Most smallholder farmers are experiencing food insecurity. Based on the findings of the study, it was recommended that there was the need to encourage people owning land less than five acres to practice mixed farming, use scientific methods of farming such as intercropping crop rotation, and use fertilizers to facilitate better yields and crop diversification to improve both on their earnings and food security.
Spontaneous mood improvement by negative memories Negative Memories Can Boost Positive Moods Beyond Memory Incongruence Effect

The role of autobiographical memory in emotion regulation is deemed as limited to the selective retrieval of positive memories intended as a distraction from unpleasant stimuli. The present experimental study is the first to examine whether negative autobiographical memories serve as a way to boost one’s mood by employing the mechanism of retrospective downward autobiographical comparison between now and then. We hypothesised that this mechanism may operate in response to negative memories, leading to positive mood induction. Ninety-nine students participated in four memory tasks: autobiographical positive, autobiographical negative, vicarious positive, and vicarious negative. Emotional states at pre-and post-tests were assessed using the implicit test differentiating positive (PA) and negative (NA) components of mood. The results replicated previous studies on the mood-repair effect of deliberate positive recall. The most striking finding is that negative autobiographical recall consistently boosted PA and inhibited NA. This result supported the idea of retrospective downward autobiographical comparison as a plausible mechanism behind the efficacy of negative memories in emotion regulation.
Ising n-fold integrals as diagonals of rational functions and integrality of series expansions: integrality versus modularity

We show that the n-fold integrals $\chi^{(n)}$ of the magnetic susceptibility of the Ising model, as well as various other n-fold integrals of the"Ising class", or n-fold integrals from enumerative combinatorics, like lattice Green functions, are actually diagonals of rational functions. As a consequence, the power series expansions of these solutions of linear differential equations"Derived From Geometry"are globally bounded, which means that, after just one rescaling of the expansion variable, they can be cast into series expansions with integer coefficients. Besides, in a more enumerative combinatorics context, we show that generating functions whose coefficients are expressed in terms of nested sums of products of binomial terms can also be shown to be diagonals of rational functions. We give a large set of results illustrating the fact that the unique analytical solution of Calabi-Yau ODEs, and more generally of MUM ODEs, is, almost always, diagonal of rational functions. We revisit Christol's conjecture that globally bounded series of G-operators are necessarily diagonals of rational functions. We provide a large set of examples of globally bounded series, or series with integer coefficients, associated with modular forms, or Hadamard product of modular forms, or associated with Calabi-Yau ODEs, underlying the concept of modularity. We finally address the question of the relations between the notion of integrality (series with integer coefficients, or, more generally, globally bounded series) and the modularity (in particular integrality of the Taylor coefficients of mirror map), introducing new representations of Yukawa couplings.
High-Precision Benchmarks for the Stochastic Rod

We demonstrate a method to calculate high-precision benchmarks for the reflectance and trans-mittance of a finite rod with a stochastic cross section, assuming that the attenuation law has a known closed form and both the single-scattering albedo and scattering kernel are deterministic. We introduce new 10-digit values for an existing binary-Markov benchmark (including mean and variance), along with several new benchmarks defined for non-Markov binary mixtures and a continuous fluctuation model featuring gamma stationary statistics. Furthermore, we reveal that our analysis of scattering in the stochastic rod results in an efficient algorithm for identifying the parameters of an n -ary Markov mixture that most accurately approximates a given non-Markov system.
Formation of Refuge Areas Behind Alternative Gravel Mounts for Fishes During Flood Stages

: The alternative construction of gravel mounts in channelized rivers is expected to successfully increase the flow heterogeneity and create refuge areas where aquatic animals may hide during floods stages. Five physical models were investigated using three different gravel mount’s heights h gm above two slope steepness. Comparisons were made with two further experiments above flat gravel bed conditions. Both the discharge Q = 0.0588 m 3 /s (simulation of medium-sized flood) and the distance between gravel mounts L = 1.60 m were kept constant throughout the research. Water surface profile and velocity field characterize the flow conditions, where two thresholds are used to define refuge areas: mean velocity 10 cm/s and standard deviation of the velocity 7 cm/s. After the installation of gravel mounts, oscillations are formed in the center of the channel, which amplitude increased above steeper channel slopes. Water surface rise is confirmed, but the impact on flood protection could no be quantify outside model conditions. The expected hydraulic conditions for refuge areas are generally met close to the gravel bed behind each gravel mount, while the relative size of the refuge volume per gravel volume is the largest for h gm /L=0.03. The flow stability inside refuge areas is confirmed with a fast Fourier transform.
Screwworm Research and Eradication

At a former air base converted to an insectary, fly sterilization and dispersal center, near Mission, Texas, the Animal and Plant Health Inspection Service (APHIS) of the USDA is producing and distributing approximately 200 million sterile screwworm flies, Cochliomyia hominivorax (Coquerel), per week. Meanwhile, there is under construction another screwworm plant near Tuxtla Gutierrez, Chiapas, Mexico. This facility belongs to the Mexico-United States Commission for the Eradication of Screwworms. The new insectary is planned to begin producing 300 million flies weekly about a year from now.
Exploring Characteristics of Self-De ﬁ ning Memories in Older Adults

The aim of this descriptive study was to investigate the Self-De ﬁ ning Memories (SDMs) in a large sample of 181 older adults (65 – 90 years; mean age = 73.0 years) and to target the relationships between their different dimensions. The sampling method was nonprobabilistic, based on voluntary participation. Participants were asked to recall three SDMs. They also completed the Mini-Mental State Examination, the Hospital Anxiety and Depression Scale, and a Self-esteem Scale. Almost half of the SDMs were speci ﬁ c and more than a quarter were integrated. Speci ﬁ city, tension, redemption, contamination sequences, and affective response varied regarding thematic content. Speci ﬁ city was positively correlated to tension whereas autobiographical reasoning was positively correlated to redemption and negatively linked to emotional response and depression. This research highlighted that identity is constituted by the main types of events that make up a life: interpersonal relationships, life-threatening events, achievement, and leisure.
Work The Daily Dynamics of Basic Psychological Need Satisfaction at Work, their Determinants

Drawing on self-determination theory, this study focuses on the person-and occasion-specific components of the daily dynamics of employees' global psychological need satisfaction at work. Predictors (job demands related to information and communication technologies, segmentation norms, and workload) and outcomes (perceived productivity, psychological detachment, work-family conflict, job satisfaction, and personal satisfaction) were also examined across both levels to better grasp the mechanisms underlying these short-term dynamics. A total of 129 French employees filled out questionnaire surveys at the end of each workday for five days (521 observations). Results from Dynamic Structural Equation Modeling (DSEM) showed clear associations between need satisfaction, the predictors, and the outcomes at the person-specific level. However, and although need satisfaction levels were found to fluctuate on a daily basis, they seemed immune to the effects of daily fluctuations in predictors levels, and unlikely to generate matching fluctuations in outcome levels. These results suggest strong homeostatic processes protecting employees' functioning against daily fluctuations, but that the accumulation of such fluctuations over the work week may jeopardize these processes.
Silicon nitride optical waveguide parametric ampli�ers with integrated graphene oxide �lms

Optical parametric ampli�cation (OPA) represents a powerful solution to achieve broadband ampli�cation in wavelength ranges beyond the scope of conventional gain media, for generating high-power optical pulses, optical microcombs, entangled photon pairs and a wide range of other applications. Here, we demonstrate optical parametric ampli�ers based on silicon nitride (Si 3 N 4 ) waveguides integrated with two-dimensional (2D) layered graphene oxide (GO) �lms. We achieve precise control over the thickness, length, and position of the GO �lms using a transfer-free, layer-by-layer coating method combined with accurate window opening in the chip cladding using photolithography. Detailed OPA measurements with a pulsed pump for the fabricated devices with different GO �lm thicknesses and lengths show a maximum parametric gain of ~ 24.0 dB, representing a ~ 12.2 dB improvement relative to the device without GO. We perform a theoretical analysis of the device performance, achieving good agreement with experiment and showing that there is substantial room for further improvement. This work demonstrates a new way of achieving high photonic integrated OPA performance by incorporating 2D materials.
Monitoring of COVID-19 Disease based on Modern Technologies

Introduction: Coronavirus has become a global pandemic since early 2019. More than180 countries around the world are involved with COVID-19. One of the effective methods to monitor, detect, warn early, prevent, and control is Information Technology. Methods: This study is a scoping review. This study aimed to describe the novel information technologies used during the COVID-19 pandemic. The literature was searched for types of information technologies on COVID-19 with the help of libraries, electronic databases (Scopus, PubMed, and Web of sciences), and search engines available at Google. Results: In this study, three groups of telemedicine technologies including telediagnosis, telemonitoring, and teleconsultation were selected. In addition, several unique technologies such as artificial intelligence, smart wearable devices, big data, neural networks, robots, chatbots, close contact detectors, Internet of Things (IoT), smart drones, Electronic Health Records, and thermal scanners were included. More than 150 resources were collected, 68 of whom were selected based on their relevancy during 2021. The results showed that the role of modern technologies in healthcare systems monitoring was crucial during COVID-19 pandemic. Conclusion: Therefore, telemedicine is one of the solutions that has been equivalent to or even better than face-to-face medicine, and governments should better learn about the experiences of different countries in the use and their branches such as Telemonitoring, Teleconsultation, Telediagnosis along with enforcing laws to follow the protocols and vaccination of different groups of society to prevent the spread of the disease.
Study of Plasma Cyclic Guanosine Monophosphate as a New Marker in Patients with Portal Hypertension

Background: Clinically significant portal hypertension (CSPH), causes a number of problems that is linked to decreased survival. Its diagnosis done by measuring the hepatic venous pressure gradient (HVPG). Although being invasive but gold standard one. In addition to fibrotic liver tissue remodeling, poor vasotonus control plays a role in the pathophysiology of portal hypertension (PH) in liver cirrhosis. Research on PH-affected animal models has shown that hepatic cGMP activity is reduced while systemic and splanchnic cGMP activity are reflectively elevated. These changes are part of what causes cirrhotic PH, which is characterised by hyperdynamic systemic and splanchnic circulation as well as profuse hepatic vascular resistance. This pathophysiological context implies that cGMP may serve as a PH marker. Objective: The aim of the current study was for evaluation of plasma level of cyclic guanosine monophosphate (cGMP) as a surrogate non-invasive biomarker of portal hypertension. Patients and methods: This case control study were performed at Ain Shams University Hospitals Inpatients and Outpatients’ settings for one year. It included 40 cirrhotic patients with portal hypertension (Group I), 40 cirrhotic patients without PH (Group II), and 20 healthy controls (Group III). The following investigations were assessed for all study subjects: plasma cGMP, and abdominal US with portal vein duplex. Upper endoscopy was performed only for group I. Results: This study showed high statistically significant difference between the studied groups as regards plasma cGMP. Also, there was a statistically significant correlation between cGMP and portal vein diameter and splenic diameter in group I, but there was no statistically significant relation between plasma cGMP and presence of esophageal varices in group I. ROC curve for plasma cGMP to differentiate between cirrhosis cases with and without PH showed at cut off point > 53.6 plasma cGMP had a sensitivity of 95%, and specificity of 100% to detect portal hypertension in patient with liver cirrhosis. Conclusion: cGMP can be used as a noninvasive biomarker of portal hypertension. Also, cGMP at a cut off value >53.6 (with 99.4% accuracy) had 95% sensitivity, and 100% specificity. However, cGMP couldn’t be used as a screening for esophageal varices.
Diagnostic Value of Ascitic Endocan in Spontaneous Bacterial Peritonitis

Article information Background: Endocan is a potential marker of many immune-inflammatory conditions. It may be linked to liver cirrhosis. Increased endocan levels is linked to liver diseases [e.g., chronic hepatitis] which could be developed to liver decompensation and may be elevated in ascetic fluid. Aim of the work: The current work aimed to evaluate the role of ascetic endocan in the diagnosis of Spontaneous Bacterial Peritonitis [SBP] among patients with decompensated cirrhosis. Patients and Methods: In this cross-sectional study, 100 patients with cirrhotic ascites were selected from patients who were admitted to Nasser institute and Al-Azhar University Hospitals during the period from April 2022 to April 2023. All patients were assessed on a clinical basis, and laboratory investigations were performed. The ascetic levels of endocan were measured and compared between groups. Results: Both groups were comparable regarding patient demographics. All patients in non-SBP had negative culture, while 12 patients in SBP group had positive results [10 of E-Coli, one Klebsiella and one Streptococcus viridans]. The major cause of cirrhosis in both groups was the HCV [76% of SBP compared to 80% of the non-SBP group]. The endocan levels showed a significant increase in the SBP than the non-SBP groups [5.20±1.80 vs 2.96±1.80 ng/ml]. Endocan significantly and positively correlated with each of TLC, AST, ALT, creatinine, albumin, bilirubin, INR, CRP, HBsAg and HCV antibodies. The hazardous ratio [HR] for endocan was 1.644 [95% CI: 1.011 – 2.707]. The endocan is also predictive of SBP development with an HR 1.673 [95% CI:1.031 – 2.806]. Conclusion: Ascetic Endocan is increased in ascitic fluid and represents an independent risk factor for SBP, with a significant diagnostic value in patients with decompensated cirrhosis.
Efforts In Improving The Ability Of Observation Report Text Writing Through Discovery Learning Model Containing Banyumas Culture Of Batiks Making

This study aimed to determine improvement in the ability of observation report text writing through discovery learning model containing Banyumas culture of making batiks. This classroom action study was conducted in 2 cycles. The objects of this study were the result of observation report text writing on students’ batik making activities. Based on the discussion result, it can be concluded that through discovery learning model, the students could improve their skills in writing observation report text. This was proven by average scores in each cycle, such as: the average score of pre-tests was 53,6, the average score in cycle 1 was 65,55; cycle 2 was 73,05. Moreover, from the observation result, it found that students who have low scores tend to be passive, out of focus, and quickly get bored in learning process. That was proven by students who were sleepy and less enthusiastic caused by exhaustion. In contrast to the students who have low scores, the high-scores students tend to be more active and excited in paying attention during learning process.
