The Qualitative Report The Qualitative Attributes and Qualifications of Successful Rural Nurse Attributes and Qualifications of Successful Rural Nurse Preceptors: Preceptors’ Perspectives Preceptors: Preceptors’ Perspectives

Abstract Nurse preceptors are integral to retaining new nurses. Given the challenges associated with attracting and retaining rural nurses (Trossman, 2001), the importance of preceptors in the retention of new nurses and the dearth of studies explicitly examining the attributes and qualifications of successful rural nurse preceptors, the purpose of this study was to unearth attributes and qualifications of successful rural nurse preceptors. In this basic qualitative study, 19 participants completed 1-2 hour in-depth interviews. Data was analyzed using the constant comparative method (Glaser & Strauss, 1967). Major themes included a sense of honor, professionalism, self-efficacy, and the ability to learn. In addition to confirming previous research, the findings demonstrated the importance of emotion in the teaching/learning process and the influence of observational learning on preceptors’ present-day instruction. Practical implications included acknowledging emotion in the teaching/learning process, the need for new and experienced preceptors to share information and the importance of creating opportunities for critical reflection in preceptor education programs.

A systematic security analysis of the AODV protocol A systematic security analysis of the AODV protocol

Wireless networks are becoming a pervasive element of today's computing. With this growth a new type of network is being researched, the ad-hoc network. Wireless ad-hoc networks bring the advantage of flexibility because of the dynamic way that they are formed and left. Looking at these networks, with scenarios such as a tactical battlefield in mind, gives rise to many security issues. Because of the relative newness of wireless ad-hoc networks there is no standard routing protocol for the network layer. Many protocols have been proposed, and this thesis will examine one of the more popular protocols, Ad-hoc On-Demand Distance Vector Routing. With the growing need for security in mind, an analysis of this protocol will be done with relation to the security threats that are prevalent on today's tactical wireless networks. This will then determine the usability of the protocol in such environments were security is a key factor.

Novel series of pyrrolylbenzamide derivatives were synthesized with an aim to combat the increasing anti-tubercular resistance and to develop more potent anti-tubercular agents with reasonably less side effect. Herein, we synthesized a series of substituted 2-(2,5-dimethyl-1 H -pyrrol-1-yl)phenyl)benzamides (3a-f) by reacting different substituted aromatic acids with 2-(2,5-dimethyl-1 H -pyrrol-1-yl)aniline (2) by using HBTU as a coupling agent, DIEA as a
Predictors of an adverse course of heart failure with preserved left ventricular ejection fraction in patients with obstructive sleep apnea syndrome

Aim. To study the relationship of obstructive respiratory disorders during sleep with subclinical development of right ventricular dysfunction and pulmonary hypertension, as well as with the risk of an adverse course of chronic heart failure (CHF) with preserved left ventricular ejection fraction (LVEF). Materials and methods. The study included 86 men with moderate and severe forms of obstructive sleep apnea syndrome (OSAS) (with an apnea / hypopnea index (AHI) > 15 per hour). All patients had abdominal obesity and hypertension. Upon inclusion in the study, all patients underwent polysomnography and echocardiography according to the standard protocol with an additional assessment of the fractional area change in the right ventricular myocardium (ΔSRV) and the right ventricular stroke work index (RVSWI). Also, the content of the N-terminal brain natriuretic peptide precursor (NT-proBNP) in the blood serum was determined by enzyme immunoassay analysis. A six-minute walk test (6MWT) was performed after inclusion in the study and after 12 months of follow-up. Depending on the course of CHF during the follow-up, retrospectively, the patients were divided into 2 groups: with an unfavorable ( n = 33) and favorable ( n = 53) prognosis. Results. A significant relationship between AHI and ΔSRV, RVSWI, NT-proBNP, and 6MWT was revealed. Based on the results of one-way correlation analysis, it was found that ΔSRV (odds ratio (OR) 2.51; 95% confi dence interval (CI) 2.42–3.24; p = 0.0009), NT-proBNP (OR 1.92; 95% CI 1.32–2.78; p = 0.003), and AHI (OR 3.93; 95% CI 2.87–4.11; p = 0.018) were predictors of an adverse course of CHF. In a multivariate analysis, it was found that AHI was an independent predictor of an adverse course of CHF (OR 3.49; 95% CI 2.17–11.73; p = 0.0008), while the addition of NT-proBNP improved risk stratification of an adverse course of CHF (OR 4.66; 95% CI 3.87–13.11; p < 0.0001). Conclusion. The fractional area change in the right ventricular myocardium (ΔSRV) can be considered as a non-in vasive marker for determining the emerging right ventricular dysfunction and predicting adverse cardiovascular events in patients with preserved LVEF and OSAS. Moreover, the combined use of echocardiographic (ΔSRV) and laboratory (NT-proBNP) markers can improve risk stratification of CHF progression.
Institutional Knowledge at Singapore Management University Putting their Best Foot Forward: Emotional Disclosure on Facebook

Facebook has become a widely used online self-representation and communication platform. In this research, we focus on emotional disclosure on Facebook. We conducted two studies, and results from both self-report and observer rating show that individuals are more likely to express positive relative to negative emotions and present better emotional well-being on Facebook than in real life. Our study is the ﬁrst to demonstrate impression management on Facebook through emotional disclosure. We discuss important theoretical and practical implications of our study.
Spreading of Infections on Network Models: Percolation Clusters and Random Trees

: We discuss network models as a general and suitable framework for describing the spreading of an infectious disease within a population. We discuss two types of ﬁnite random structures as building blocks of the network, one based on percolation concepts and the second one on random tree structures. We study, as is done for the SIR model, the time evolution of the number of susceptible (S), infected (I) and recovered (R) individuals, in the presence of a spreading infectious disease, by incorporating a healing mechanism for infecteds. In addition, we discuss in detail the implementation of lockdowns and how to simulate them. For percolation clusters, we present numerical results based on site percolation on a square lattice, while for random trees we derive new analytical results, which are illustrated in detail with a few examples. It is argued that such hierarchical networks can complement the well-known SIR model in most circumstances. We illustrate these ideas by revisiting USA COVID-19 data. which interconnected dynamically spreads the network. The clusters are constructed or designed in such a way that their internal spreading dynamics can be solved either numerically or analytically, and their contributions to the total infections in the network can be sequentially such that one can mimic the time evolution of the infectious disease in a real We discuss how the number of clusters participating in the network can be adjusted to reproduce the speeding up of the number of infecteds at the initial stages of the breakout, and how lockdowns can be simulated in a simple fashion. We discuss two different approaches to this problem which can be used for describing real spreading data. very
Effectiveness Of Direct Feedback Versus Indirect Feedback In The Learning Of English As A Second Language

This is a report of a study which evaluated the direct feedback intervention to improve Grade 1 ESL pupils in a Malaysian primary school context. Although direct feedback is well-known in the North American continent, in the Malaysian context this instructional approach is largely unknown. Further some research works in this area suggest that that reading comprehension strategy instruction is not carried out in the majority of reading classrooms. We used a quasi-experimental approach with nonequivalent control group design to collect the causal connections between intervention and outcomes. For the purpose of this study, an independent-samples t-test was conducted to compare reading performance of Grade 1 Malaysian ESL students with direct feedback and no direct feedback. Unpaired ttest was carried out for direct feedback (N= 40, Mean=67.65 and SD=5.45) and control group (N=35, Mean=50.37, SD=2.98) conditions with t = 16.69 (df=73, and standard error of difference=1.035) and the two-tailed P-value was less than 0.0001 and by conventional criteria suggested a very high practical significance. The effect size for the post-test intervention revealed that really large (Ellis, 2009) Cohen’s d effect size of (3.93) and Hedges’ g of (3.82) for contravening variables were found. In an ESL Malaysian context, the direct feedback to improve Grade 1 ESL pupils may have some advantages in improving the English reading performance. However, the bene ﬁ ts to the students of this study is still to be determined, and further exploration is needed with well-designed research and a universal method of outcome measurements.

The Update of Fetal Growth Restriction Associated with Biomarkers

Abstract Fetal growth restriction (FGR) has a prevalence of about 10% worldwide and is associated with an increased risk of perinatal mortality and morbidity. FGR is commonly caused by placental insufficiency and can begin early (<32 weeks) or in late (≥32 weeks) gestational age. A false positive antenatal diagnosis may lead to unnecessary monitoring and interventions, as well as cause maternal anxiety. Whereas a false negative diagnosis exposes the fetus to an increased risk of stillbirth and renders the pregnancy ineligible from the appropriate care and potential treatments. The clinical management of FGR pregnancies faces a complex challenge of deciding on the optimal timing of delivery as currently the main solution is to deliver the baby early, but iatrogenic preterm delivery of infants is associated with adverse short- and long-term outcomes. Early and accurate diagnosis of FGR could aid in better stratification of clinical management, and the development and implementation of treatment options, ultimately benefiting clinical care and potentially improving both short- and long-term health outcomes. The aim of this review is to present the new insights on biomarkers of placenta insufficiency, including their current and potential value of biomarkers in the prediction and prevention for FGR, and highlight the association between biomarkers and adverse outcomes in utero to explore the specific mechanism of impaired fetal growth that establish the basis for disease later in life.
Systematic Review of the “Pragmatism” of Pragmatic Critical Care Trials

OBJECTIVES: To assess the pragmatism of published critical care randomized controlled trials self-described as pragmatic using a validated tool. DATA SOURCES: Medical Literature Analysis and Retrieval Online database and PubMed interface from inception to November 1, 2021. STUDY SELECTION: We performed a systematic search of randomized controlled trials evaluating interventions for critically ill adults that self-identified as pragmatic in title or abstract. DATA EXTRACTION: Reviewers independently performed study selection and data extraction in duplicate; discrepancies were resolved by consensus. Pragmatism was assessed independently in duplicate by trained reviewers using the Pragmatic-Explanatory Continuum Indicator Summary 2 (PRECIS-2), a validated tool designed to represent how explanatory/pragmatic a trial is on the pragmatic to explanatory continuum. Trials were scored in nine domains on a 5-point continuum (from 1 = very explanatory to 5 = very pragmatic). Discrepancies of greater than 2 points were adjudicated by consensus discussion. DATA SYNTHESIS: The search resulted in 284 studies; 56 met eligibility criteria. Forty-one of the trials had a discrepancy in at least one domain that required consensus discussion, most commonly in domains of eligibility and follow-up. Twelve studies (21.4%) were scored as “overall pragmatic,” defined as score of greater than 4 in five domains provided the scores in the remaining domains were three. The overall PRECIS-2 score of self-identified pragmatic studies increased from 1995 to 2021 suggesting increasing pragmatism over time. Pragmatic trials were more likely to have a waiver of informed consent (p = 0.05). CONCLUSIONS: The number and pragmatism of self-identified pragmatic trials have increased, particularly in the past decade. However, less than one-quarter of these trials that use the term pragmatic in title or abstract were retrospectively rated as pragmatic. Our results support the concept that trials are designed on a spectrum of pragmatic to explanatory. Advances in the design and reporting of critical care trials are needed to ensure their real-world applicability.
Quantitative morphology of isolated E/S pairs of galaxies

A study of the morphology and geometry for 22 southern E+S pair candidates is presented, using high resolution CCD frames obtained at the ESO 2.2 m telescope. A considerable number of true mixed pairs with ∼13/11 elliptical + spiral pairs in the present sample is found. The remaining objects include ∼3 «disky» pairs (composed of S0 and S members) and 3 «early-type» pairs comprising E and S0 members. We estimate that between 10 and 25% of the pairs in any complete (non-hierarchical) sample will be of the E+S type. This suggests that morphological concordance is not the rule among paired galaxies

Models of EFL Thai Readersû Reading Process: Evidence from Thai Graduate Studentsû Translation

This paper presents the results of a qualitative research study that aimed to find out the reading process of EFL Thai learners. The data were collected by using a translation test administered to Masterûs degree students majoring in Business Economics and in Administration Technology at National Institute of Development Administration. They were divided by their performance on the test into good, average, and poor reader groups. The translation papers of only those in the poor reader group were analyzed and some of the students were selected for interview to find out what strategies they used in constructing the meaning of each text in the test. Those in the good reader group were also interviewed about their strategies too, but their papers were not analyzed. It was found that poor readers relied mainly on top-down-processing, using their background knowledge of the world in constructing the meaning of the texts they read, while good readers used both bottom-up processing and top-down processing alternatively and simultaneously in their reading. Both groups started reading by finding out what the text was about, but they differed in the way they interpret the information. Also, while poor readers skipped many words in the text,
A Deep Learning Methodology for Semantic Utterance Classification in Domain-Specific Dialogue Systems

Recent advances in deep learning approaches have transformed fields such as natural language and image processing. In particular, these new advances have the potential to transform dialogue systems which are traditionally implemented using language model based or boosting approaches. In this work, we have proposed a deep learning framework to perform semantic utterance classification (SUC) for use in domain-specific dialogue systems. Deep learning has only recently been used for SUC but has not been used with domain-specific word embeddings or dialogue systems. Semantic classifiers need to account for a variety of instances where the utterance for the semantic domain class varies. In order to capture the candidate relationships between the semantic class and the word sequence in an utterance, we have proposed a shallow convolutional neural network (CNN) that uses domain-specific word embeddings, that has been initialized using word2vec for determining semantic similarity of words. These embeddings can remain static, be updated during training or can even be created from scratch for the particular intent determination task at hand. ii
Multi-Pool Based Resource Allocation Scheme in Broadband SATCOM System

—A Multi-Satellite Broadband Network (MSBN) appears to be a promising network for providing efﬁcient and seam-less multimedia services. To maximize the resource utility and optimize the Quality of Service (QoS) in MSBN, reasonable bandwidth allocation method is, indeed, important. State-of-the-art bandwidth algorithms, which are mostly based on the allocation of a single satellite-ground link, ignore limited trafﬁc capacities in other links, such as inter-satellite links. In this paper, a Multi-Pool based Bandwidth Allocation (MPBA) scheme is proposed to solve this problem. Firstly, a typical multi-pool framework is built to manage bandwidth resources of all communication links instead of the traditional single satellite-ground link, and the corresponding resource allocation process is analyzed. Secondly, inspired by the non-cooperative game theory, the MPBA algorithm with a low computation complexity is designed to ensure different QoS demands of multimedia services. Extensive experiments are carried out, and results obtained demonstrate that our multi-pool framework can achieve improvement on the end-to-end delay and the network resource utility over existing bandwidth allocation methods in MSBN.
Impact Of Abet 2000 On Teaching Engineering Economics: What Subjects Define Economic Literacy For Engineers?

This paper addresses a major assessment issue for those who teach engineering economics and related courses. That is, what subjects do we teach, how important are they and do they impact the ABET EC 2000 criteria. To determine these subjects, a list was developed that utilized previous ASEE/EE papers and a review of engineering economics texts. A survey was conducted of engineering graduates who work for companies that hire engineers, who started their careers as engineers and who have supervised engineers. The survey asked the respondents to rank the selected economics topics using a 1 strongly disagree to 5 strongly agree Likert scale. Even though a broad set of subjects was chosen, all subjects had above average scores of more than 3.0/5.0, indicating that none of the major subjects were clearly eliminated. This result indicates that engineers need to know a broad set of subjects to achieve economic literacy. Risk Analysis Fundamentals and Simulation Models were rated high, 4.0 and 3.7 respectively, although they are usually taught in more advanced engineering economics courses. The survey averages for more traditional topics such as Cost Estimation and Cost Accounting Fundamentals, 4.0 and 3.8, and Engineering Economics Basic and Advanced 3.9 and 3.5 were high, as expected. So, too, were the rankings for Fundamentals of Basic and Financial Accounting, 3.6 and 3.5.
Strategic Consumption-Portfolio Rules with Informational Frictions

This paper provides a tractable continuous-time CARA-Gaussian framework to explore how the interactions of risk aversion and induced uncertainty due to informational frictions determine strategic consumption-portfolio rules, precautionary savings, and consumption dynamics in the presence of uninsurable labor income. Speciﬁcally, after solving the model explicitly, we explore the relative importance of the two types of induced uncertainty: (i) model uncertainty due to robustness and (ii) state uncertainty due to limited information-processing capacity as well as risk aversion in determining asset allocation, precautionary savings, and consumption dynamics. Finally, we discuss how the separation between risk aversion and intertemporal substitution affects strategic asset allocation and precautionary savings.

A reappraisal on biodegradation of fluoride compounds: role of microbes

Fluorine is a highly reactive gas, rarely occurs in nature, in elemental form. Fluorosis is an excruciating and crippling disease caused by fluoride intake. Microbial degradation is cost‐effective and eco‐friendly method of removing fluoride compounds. The enzymes and genes involved in the fluoride‐degrading pathway have been identified and characterised. The in‐silico studies on degradative enzymes and their molecular interaction can be more advantageous in understanding fluoride toxicity and its degradative efficiency. Microbes exhibiting fluoride degradative potential or fluoride adsorption potential can be used for bioremediation of fluoride‐contaminated water. Large population is affected by fluorosis; both the welfare state and researchers are required to address the problem. The microbial degradation of fluoride provides sustainable, cost‐effective and ecofriendly technology. In the present review, an attempt has been made to compile all the available literature related to biodegradation of fluoride compounds.
