Critical care nurses and their clinical reasoning for customizing monitor alarms:a mixed-method study

Objective:To explore the clinical rationale of critical care nurses for personalizing monitor alarms.One of the most crucial jobs assigned to critical care nurses is monitoring patients'physiological indicators and carrying out the necessary associated interventions.Successful use of equipment in the nursing practice environment will be improved by a thorough understanding of the nurse's approach to alarm configuration.Methods:A mixed-method design integrating quantitative and qualitative components was used.The sample of this study recruited a convenience sample of 60 nurses who have worked in critical care areas.This study took place at Lebanese American University Medical Center Rizk Hospital,utilizing a semi-structured interview with participants.Results:The study demonstrated the high incidence of nuisance alarms and the desensitization of critical care nurses to vital ones.According to the nurses,frequent false alarms and a shortage of staff are the 2 main causes of alarm desensitization.Age was significantly associated with the perception of Smart alarms,according to the data(P=0.03).Four interconnected themes and subcategories that reflect the clinical reasoning process for alarm customization were developed as a result of the study's qualitative component:(1)unit alarm environment;(2)nursing style;(3)motivation to customize;and(4)clinical and technological customization.Conclusions:According to this study,nurses believe that alarms are valuable.However,a qualitative analysis of the experiences revealed that customization has been severely limited since the healthcare team depends on nurses to complete these tasks independently.Additionally,a staffing shortage and lack of technical training at the start of placement have also hindered customization.

An Explanation of the Temperature-Dependent Upper Critical Field Data of H3S on the Basis of the Thermodynamics of a Superconductor in a Magnetic Field

Excellent fits to a couple of the data-sets on the temperature (T)-dependent upper critical field (Hc2) of H3S (critical temperature, Tc ≈ 200 K at pressure ≈ 150 GPa) reported by Mozaffari, et al. (2019) were obtained by Talantsev (2019) in an approach based on an ingenious mix of the Ginzberg-Landau (GL), the Werthamer, Helfand and Hohenberg (WHH), and the Gor’kov, etc., theories which have individually been employed for the same purpose for a long time. Up to the lowest temperature (TL) in each of these data-sets, similarly accurate fits have also been obtained by Malik and Varma (2023) in a radically different approach based on the Bethe-Salpeter equation (BSE) supplemented by the Matsubara and the Landau quantization prescriptions. For T TL, however, while the (GL, WHH, etc.)-based approach leads to Hc2(0) ≈ 100 T, the BSE-based approach leads to about twice this value even at 1 K. In this paper, a fit to one of the said data-sets is obtained for the first time via a thermodynamic approach which, up to TL, is as good as those obtained via the earlier approaches. While this is interesting per se, another significant result of this paper is that for T TL it corroborates the result of the BSE-based approach.

Intensive care environment: Perspective of relatives of critically ill patient sustained by health technology

The intensive care unit(ICU)is a complex setting by nature,and some have described it as bizarre due to its numerous sirens that sound when anything is dangerous,constant activity,equipment,bright lights,and high fatality rate.The demands placed on nurses to care for critically ill patients in this environment frequently prevent nurses and other health‑care professionals from acknowledging the feelings of patient’s relatives or family caregivers,resulting in a hostile environment from the patient’s relative’s perspective.When a patient’s family enters the ICU,they feel that hospital administrators do little to nothing to alleviate their discomfort and fear.Despite research demonstrating the importance of providing a homely environment for patients’families,In Nigeria ICU is still far behind how a conventional ICU environment should be structured to accommodate patient’s relations in the unit.The goal of this study was to look at the patient’s relative’s perspective on providing care for a critically ill patient in an ICU,with a focus on the unit’s complexity and overall experience.Based on the findings of this study,we recommend that hospital administrators ensure that the environment of the upcoming ICU is designed to meet the needs of patient’s relatives by addressing identified environmental concerns,like caring neglect,by providing a friendly and stress‑free environment.

On the Relationship between T. S. Eliot and the New Criticism from Their Opinions on Literary Work and Reader

T. S. Eliot is always considered as the pioneering father and founder of the New Criticism. This paper compares the similarities and differences of T. S. Eliot's relevant theories with those of the New Criticism from two aspects: their viewpoints of the literary works and those of the reader. It concludes that though they share the same belief in the importance of the literary works, the New Criticism is good at the subtle analysis of one text and another. However, Eliot recognizes the reader's function in the appreciation of the works which New Criticism totally objects to, and their responses should be properly considered in the criticism of the works.

A Dynamical Approach to the Explanation of the Upper Critical Field Data of Compressed H3S

Excellent fits were obtained by Talantsev (MPLB 33, 1950195, 2019) to the temperature (T)-dependent upper critical field (Hc2(T)) data of H3S reported by Mozaffari et al. [Nature Communications 10, 2522 (2019)] by employing four alternative phenomenological models, each of which invoked two or more properties from its sample-specific set S1 = {Tc, gap, coherence length, penetration depth, jump in sp.ht.} and a single value of the effective mass (m*) of an electron. Based on the premise that the variation of Hc2(T) is due to the variation of the chemical potential μ(T), we report here fits to the same data by employing a T-, μ- and m*-dependent equation for Hc2(T) and three models of μ(T), viz. the linear, the parabolic and the concave-upward model. For temperatures up to which the data are available, each of these provides a good fit. However, for lower values of T, their predictions differ. Notably, the predicted values of Hc2(0) are much higher than in any of the models dealt with by Talantsev. In sum, we show here that the addressed data are explicable in a framework comprising the set S2 = {μ, m*, interaction parameter λm, Landau index NL}, which is altogether different from S1.

Rock critical porosity inversion and S-wave velocity prediction

A critical porosity model is often used to calculate the dry frame elastic modulus by the rock critical porosity value which is affected by many factors. In practice it is hard for us to obtain an accurate critical porosity value and we can generally take only an empirical critical porosity value which often causes errors. In this paper, we propose a method to obtain the rock critical porosity value by inverting P-wave velocity and applying it to predict S-wave velocity. The applications of experiment and log data both show that the critical porosity inversion method can reduce the uncertainty resulting from using an empirical value in the past and provide the accurate critical porosity value for predicting S-wave velocity which significantly improves the prediction accuracy.

Critical emancipatory reflection on a practice-based issue in relation to the working relationship between doctors and nurses in China

Objective: Reflection is viewed as the most significant skill and should be advocated for lifelong learning. In order to grasp the process of reflection and embrace the reflective skill, one of the authors of this paper reflects on a practice-based issue in relation to the communication between doctors and nurses, to gain new understanding and thus improve the authors' clinical practice.Methods: Smyth's framework with four stages is utilized as an ideal framework to guide the author's reflection on the practice-based issue to free the author from her entrenched assumptions and the oppressive forces that limit her practice.Results: The espoused and enacted theory, together with the critical reflection theory, are used to explore the values and beliefs that essentially govern the author's practice and how these are distinct from the author's worldviews. Following this, critical emancipatory reflection is undertaken to explore the dominant power structures within the author's workplace. Furthermore, given the hegemonic and chaotic working context of this issue, hegemony and symbolic interaction theory are applied to unearth the various hidden constraining and oppressive forces. Additionally, socialization theory is utilized to help the author achieve professional identity.Conclusions: Reconstructing the practice-based issue empowers the author to realize that in the future, she should act as a reflective practitioner, creating a daily habit, staying alert to practice, seeing things freshly, finding support systems, improving communication skills, conducting reflective research, and reifying reflective practice. Ultimately, the author will be sufficiently equipped to be able to transform her practice and change its outcomes.

Critical emancipatory reflection on establishing an equal,trusting relationship among surgery participants in clinical practice in China

Objective: Reflection is considered to be one of the important ways to learn from one's experience, and one should be encouraged to apply the skill of reflection in lifelong learning. The author used the critical emancipatory reflection theory to reflect on a practice issue,which was related to the relationship between doctors and nurses, and tries to become a lifelong reflective practitioner in clinical work.Methods: Smyth's reflective framework, which includes the steps describe, inform, confront, and reconstruct, will be used in this article to help the author to understand the process of reflection and improve the skill of reflection. Utilizing Smyth's reflective framework to reflect on an issue in practice allows the author to break the routine way of thinking and learn from experience, as well as providing a higher quality of service for patients.Results: The theory of emancipatory reflection along with the critical reflection theory will be used to determine the beliefs and values that rule the author's action and derive how these are distinct from what the author is supposed to achieve. Besides, critical emancipatory reflection theory will be used to discover the dominant power structures in clinical practice; symbolic interaction and hegemony will be utilized to discover the factors that prevent the author from achieving the desired goals; socialization theory will be applied to facilitate the author in improving the professional identity.Conclusions: Using the critical emancipatory reflection on the issue in practice helps the author to find out the constraints in practice,bridge the espoused value and enacted value, and thereafter undertake transformative changes in practice. Eventually, the author can improve the skill of critical emancipatory reflection and become a lifelong reflective practitioner, and the quality of clinical practice can be improved as a result.

Geochemical characteristics and growth suitability assessment of Scutellaria baicalensis Georgi in the Earth's critical zone of North China

Geochemical differentiation of soils has a series of consequences on plant and places pressure on the ecological environment.The quantitative evaluation of element migration in the Earth’s critical zone is a challenging task.In this study,two demonstration study areas of Scutellaria baicalensis Georgi were selected,and multiple chemical weathering indexes,chemical loss fraction,mass migration coefficients and biological enrichment coefficient method were used to assess the ecological and geochemical suitability.The results show that for the element of Fe,Zn,Se,Cu,Co,Ni,Mo and Ge,the degree of weathering and soil maturation,were greater in the rhyolitic tuff area than in the Plagioclase gneiss area.In both research sites,the heavy metal level of samples in Scutellaria baicalensis Georgi did not exceed the standard limits.The plagioclase gneiss region’s surface soil environment was more alkaline,and the content of soil organic matter was lower,resulting in a higher bioenrichment intensity of Ge,Co,Cu,and Se elements in Scutellaria baicalensis Georgi than in the rhyolite-tuff area.The elements of Cd,Nb,Mo,Pb and As are considerably enriched in the soil of the plagioclase gneiss area but lost by leaching in the soil of the rhyolite tuff area,which is connected to the interplay of elemental abundance and human impact in the parent materials.This study provides a good example of how to assess growth suitability of Chinese medicinal materials in the Earth’s critical zone.

A Corpus-Based Critical Discourse Analysis of Trump and Biden Administrations’China Policies

The theory of proximization is an effective discourse strategy to study the speaker’s ability to achieve his own legitimacy or reinforce the other’s illegitimacy,and its superiority can be maximized by means of quantitative and comparative analysis.In this study,we collected reports on Trump’s and Biden’s policies on China to build two small corpora,with a total of 11,030 words in the Trump corpus and 17,566 words in the Biden corpus.The critical discourse analysis is combined with proximization theory.With the help of BFSU Qualitative Coder 1.2,Antconc 3.5.7,and Log-Likelihood and Chi-Square Calculator 1.0,a critical cognitive score of the relevant discourse was conducted from the perspective of proximization theory.It has been found that:(1)Both Trump and Biden administrations resort to a large number of spatial proximization strategies to build ODCs converging to IDCs with China as the ODC,posing a threat to internal physical IDCs;(2)in the use of temporal proximization strategy,both administrations use primarily modal verbs and various entities to construct ODCs that extend indefinitely into the present and future,emphasizing the urgency and the threat of the effect and reinforcing the legitimacy of their actions;(3)in terms of axiological proximization strategy,the two administrations differ greatly from each other,indicating that there are still discursive biases.

Critical Literacy in Analyzing the Texts“Mulan”

Proposed in 1970 by Freire, critical literacy has attracted many scholars emerging in this field, such as Lankshear,Mclaren, Luke, Halliday, Wallace etc. From balancing social inequalities to a pedagogical approach in second language teaching,critical literacy is no longer an unfamiliar concept in daily life. To clarify how critical literacy is applied in news media, this papers focuses on two parts. Firstly, it briefly introduces the theoretical framework of critical literacy aroused in the past 40 years,and how it is implemented in children's literature. With the use of Bean and Moni's framework, a discussion of The Ballad Mulan(from Chinese history 386-581) and Disney's animated feature film Mulan(1998) puts an emphasis on the character construction and power relations. Certain aspects will be carefully analyzed, such as the powerful teenagers and weak adults, the effect of sociocultural and ideological factors in the language used in different medias, the gender identities, etc.

Critical reflection on the role of theater nurses in a multidisciplinary team for perioperative care in China

Objective: The aim of this article is to reflect on the role of theater nurses in a multidisciplinary team, understand the factors that have influenced theater nurses' practice, and improve the authors' clinical practice ultimately.Methods: The author used Smyth's model to guide the process of reflection on the practice issue. Critical reflection, critical emancipatory theory, reflexivity, and critical social theory were used to help the author analyze the factors that have affected theater nurses' practice in the organization.Results: There are gaps between the espoused and enacted theories. A theater nurse's practice is determined by multiple factors, such as political, structural, social, historical, cultural issues, and so on. The hierarchy of the health context could hinder possible changes in theater nurses' practice. To better understand our practice and implement transformation, we should shape a supportive environment,bear in mind the practice motto of "patient-centered" care, and improve our knowledge and reflection skills.Conclusions: Reflection plays a significant role in the advancing of practice among theater nurses and needs to be combined with clinical practice. To provide the best service of care to perioperative patients, a theater nurse should have an insightful understanding of the factors that have influenced her/his behaviors historically, socially, and culturally. By improving their critical reflection skills,practitioners could gain knowledge from experience.
