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. 展开更多

Objective:This paper aims at critically reflecting on the author’s personal experience in the context of communication within a nursing team and exploring relevant existing constraints with a view to improving practice and achieving more effective outcomes in team communication.Methods:Critical emancipatory reflection is used to evaluate and interpret the author’s practice.Smyth’s model serves as a framework to guide critical reflection step by step in this paper.Relevant theoretical perspectives help to make sense of the author’s performance in terms of team communication.Results:It is identified via emancipatory reflection that the author endorses the ideas of equality,respect,trust,and collaboration,which were formed and established during the process of professional socialization.However,different constraints,such as sociocultural,historical,political,and personal factors,impede the author from performing more effectively in terms of team communication.Reconstruction provides the author opportunities to take actions to rectify constraints and avoid the reemergence of previous situations in the future.Conclusions:Reflection is an effective way to gather knowledge and develop comprehensive understanding of practice.Alternative actions for effective team communication are recommended,including formulating ground rules for discussion,guiding nurses in the correct way,transforming conflicts within a team,being an active and reflective listener,and motivating nurses to actively create. 展开更多

In this paper, we investigate the Cauchy problem for the nonlocal diffusion system with localized source ut = J*u-u + a(x)v~p, v_t = J*v-v + a(x)u~q. We first prove that the Fujita curve is(pq)_c*-= 1+max{p+1, q+1}based on whether there exist global solutions, thatis, if 1 < pq(pq)_c,then every nonnegative solution blows up in finite time, but for pq >(pq)_c,there exist both global and non-global solutions to the problem. Furthermore, we establish the secondary critical curve on the space-decay of initial value at infinity. 展开更多

Blood glucose control, including hyperglycemia correction, maintaining glucose at optimal level and avoiding hypoglycemia, is a challenge clinicians face every day in intensive care units (ICUs). If managed inadequately, its related mortality can increase. Prior to 2001, no relevant data from randomized, controlled studies assessing glucose control in the ICU were available. In the past 18 years, however, many clinical trials have defined criteria for managing abnormal blood glucose levels, as well as provided suggestions for glycemic monitoring. Point-ofcare blood glucose monitors have become the preferred bedside technology to aid in glycemic management. In addition, in some institutions, continuous glucose monitoring is now available. Cost-effectiveness of adequate glycemic control in the ICU must be taken into consideration when addressing this complex issue. Newer types of glycemic monitoring may reduce nursing staff fatigue and shorten times for the treatment of hyperglycemia or hypoglycemia. There are a variety of glycemic care protocols available. However, not all ICU clinicians are aware of them. The following minireview describes some of these concepts. 展开更多

We report a direct microwave synthesis method for the preparation of 11-type high quality Fe(Te,Se)polycrys- talline superconductors.The bulk samples are rapidly synthesized under the microwave irradiation during several minutes,with a subsequent annealing process at 400℃.The samples exhibit a nearly single phase of the tetragonal PbO-type crystal structure with minor impurities.Morphology characterization shows high density,tight grain connectivity and large grain sizes around 100μm with small cavities inside the sample.Resistivity and magnetization measurements both show similar superconducting transitions above 14 K.The magnetic hystere- sis measurements display broad and symmetric loops without magnetic background,and a high critical current density Jc about 1.2 ×10^4 A/cm^2 at 2K and 7T is estimated by the Bean model.Compared with the solid- state reaction synthesized samples,these superconducting bulks from microwave-assisted synthesis are possibly free of the interstitial Fe due to smaller c-axis,higher Tc in magnetic transitions,better M-H loops without magnetic background and greatly enhanced Jc,and are promising as raw materials for the non-toxic Fe-based superconducting wires for large currents and high field applications. 展开更多

BACKGROUND Spontaneous peritonitis is an infection of ascitic fluid without a known intraabdominal source of infection. spontaneous fungal peritonitis (SFP) is a potentially fatal complication of decompensated cirrhosis, defined as fungal infection of ascitic fluid in the presence of ascitic neutrophil count of greater than 250 cells/mL. AIM To determine the prevalence of fungal pathogens, management and outcomes (mortality) of SFP in critically ill cirrhotic patients. METHODS Studies were identified using PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Scopus databases until February 2019. Inclusion criteria included intervention trials and observation studies describing the association between SFP and cirrhosis. The primary outcome was in-hospital, 1-mo, and 6- mo mortality rates of SFP in cirrhotic patients. Secondary outcomes were fungal microorganisms identified and in hospital management by anti-fungal medications. The National Heart, Lung and Blood Institute quality assessment tools were used to assess internal validity and risk of bias for each included study. RESULTS Six observational studies were included in this systematic review. The overall quality of included studies was good. A meta-analysis of results could not be performed because of differences in reporting of outcomes and heterogeneity of the included studies. There were 82 patients with SFP described across all the included studies. Candida species, predominantly Candida albicans was the fungal pathogen in majority of the cases (48%-81.8%) followed by Candida krusei (15%- 25%) and Candida glabrata (6.66%-20%). Cryptococcus neoformans (53.3%) was the other major fungal pathogen. Antifungal therapy in SFP patients was utilized in 33.3% to 81.8% cases. The prevalence of in hospital mortality ranged from 33.3% to 100%, whereas 1-mo mortality ranged between 50% to 73.3%. CONCLUSION This systematic review suggests that SFP in end stage liver disease patient is associated with high mortality both in the hospital and at 1-mo, and th 展开更多

The microscopic stripe pillar is one of the most frequently adopted building blocks for hydrophobic substrates. However, at high temperatures the particles on the droplet surface readily evaporate and re-condense on the pillar sidewall,which makes the droplet highly unstable and undermines the overall hydrophobic performance of the pillar. In this work,molecular dynamics(MD) simulation of the simple liquid at a single stripe pillar edge defect is performed to characterize the droplet’s critical wetting properties considering the evaporation–condensation effect. From the simulation results, the droplets slide down from the edge defect with a volume smaller than the critical value, which is attributed to the existence of the wetting layer on the stripe pillar sidewall. Besides, the analytical study of the pillar sidewall and wetting layer potential field distribution manifests the relation between the simulation parameters and the degree of the droplet pre-wetting, which agrees well with the MD simulation results. 展开更多

Cobbles, boulders, and rocks often are used in a bed protection layer near a structure to protect the underlying sand bed against erosion by combined current and waves. The design of a bed protection layer consisting of loose rocks (rubble mound) requires knowledge of the stability and movement (as bed load) of very coarse materials. If some movement (or damage) is acceptable, the rock diameter can be designed to be smaller. This paper addresses the stability and movement of very coarse materials (cobbles, boulders, and rocks) based on the concept of the critical Shields mobility number. It is shown that the bed load transport of large cobbles, boulders, and rocks can be described by the equations of Meyer-Peter and Mueller (MPM) and Cheng. Both are valid for relatively small Shields mobility numbers. New and general equations for the design of a bed protection layer (including some permissible damage) in conditions with a current with or without waves are proposed based on the Shields mobility parameter and the bed load transport equation of Cheng. Laboratory and field data of critical velocities for pebbles, cobbles, boulders, and rocks have been analyzed and compared to the computed results of the proposed equations. Practical applications are given to demonstrate the general applicability of the proposed equations. 展开更多

Reflection is a fundamental skill of health-care professionals and plays an important role in ensuring the quality of care in health-care practice.It is believed that undertaking reflection in practice can help nurses develop an awareness of a sense of personal power and agency,cultivate their critical thinking ability and help them promote their professional development.However,reflection has not been introduced widely as a nursing curriculum in China,and literature shows that some clinical nurses lack critical thinking skills and critical reflective practice skills by reason of not receiving systematic education on reflection when they were at nursing college.Therefore,we present a series of seven articles focused on prevalent and interesting practice-based events to reflect on in this special issue.The main aim is to disseminate reflective methodology and techniques and present examples of reflective writing for nurses.It is expected that these articles will help to lead Chinese nurses to adopt critical emancipatory reflective processes to bring about transformative actions. 展开更多

We explore the Kibble-Zurek scaling of conserved charge using stochastic diffusion dynamics. The characteristic scales τKZ and lKZ are determined and used to properly rescale the traditional correlation function and cumulant. We construct universal functions for the two-point correlation C(y1-y2;τ)and the second-order cumulant K(△y,τ) of the conserved charge in the critical regime, both of which are, near the critical point, insensitive to both the initial temperature and a parameter in the mapping between the 3D Ising model and the hot QCD system. 展开更多

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. 展开更多

Based on the neutron and proton degrees of freedom, low-lying energy levels, E2, M1, and E0 transition strengths of nucleus 124Te have been calculated by the neutron-proton interacting boson model. The calculated results are reasonably consistent with the experimental data. By comparing the key observables of the states at the critical point of Uπv(5)-Oπv(6) transition with the experimental data and calculated results, we show that the 124Te is a possible nucleus at the critical point of the second-order phase transition from vibration to unstable rotation, and such a critical point exhibits slight triaxial rotation. The 02+ state of 124Te can be interpreted as the lowest state of the first-excited family of the intrinsic levels in the critical point symmetry. 展开更多

Objective:This study aimed to demonstrate and promote the skill of critical emancipatory reflection through reflecting on a nursing practice-based ethical issue about nurses’paternalistic decision-making for patients.Meanwhile,critical awareness will be developed and the underlying issues of paternalism in nursing decision-making will be analyzed.Then,by applying the procedure,improvement in nursing decision-making practice will be expected.Methods:Taylor’s model of emancipatory reflection with four steps,including construction,deconstruction,confrontation,and reconstruction,is utilized to guide the author’s reflection.Results:Guided by the socialization theory,the author’s personal and professional socialization is seen to be associated with the formation of the value of paternalism.The theory of reflexivity is applied to unearth the related issues,including deeper personal value,work environment,as well as historical and cultural contexts.Moreover,the power derived from policy,work relationship,and nursing administration,which could induce paternalism in the author’s nursing decision-making practice,was critically debated using the hegemony theory.Finally,new insights into paternalism will be achieved,which enable change in terms of how to facilitate patients’autonomous decision-making.Conclusions:The process of refection makes it clear that respecting patients’right and performing patient-centered caring are the bases to change the paternalism existing in the nursing decision-making practice currently.The reconstruction step assists the author in terms of how to value the patients’autonomy and balance patients’safety and choice,rather than being overprotective;carry out risk assessment,and search for strong evidence to counterbalance the positive and negative aspects of risk-taking;communicate with patients appropriately in a manner that they can comprehend;spend more time to explore patients’preference and choice;make every effort to elevate the patients’decision-making capacity;implemen 展开更多

Critical rainfall estimation for early warning of rainstorm-induced flash flood is an inverse rainstorm-0x09runoff process based on warning discharge threshold for a warning station of interest in a watershed;the key aspects of critical rainfall include rainfall amount and rainfall duration. Antecedent moisture content and storm pattern affects highly the estimation of critical rainfall. Using hydrological modeling technique with detailed sub-basin delineation and manual for design rainstorm-runoff computation, this study first introduced basic concept and analysis methods on critical rainfall for flash flood early warning, and then investigated the responses of flash flood warning critical rainfall to antecedent moisture content and storm pattern. Taking South Branch Watershed of Censhui in Hunan Province as an example, critical rainfall in scenarios of typical antecedent moisture content and storm patterns was estimated at 3 warning stations of interest in this watershed. This research illustrates that both antecedent and storm pattern play important role in the estimation of critical rainfall and enough attention should also be paid to these factors when a decision to be made on whether a warning to be issued or not. 展开更多

We investigate the critical exponents and magnetocaloric effect of Co2-xZrSn polycrystal. The Co2-xZrSn undergoes a second-order ferromagnetism phase transition around the Curie temperature of Tc ~280 K. The critical behavior in the vicinity of the magnetic phase transition has been investigated by using modified Arrott plot and Kouvel–Fisher methods.The obtained critical exponents, β, γ, and δ can be well described by the scaling theory. The determined exponents of Co2-xZrSn obey the mean-field model with a long-range magnetic interaction. In addition, the maximum magnetic entropy change-?Sm ax M of Co2-xZrSn is about 0.57 J·kg-1·K-1 and the relative cooling power(RCP) is 14.68 J·kg-1 at 50 kOe(1 Oe = 79.5775 A·m-1). 展开更多

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. 展开更多
