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

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

Two metal-organic frameworks(MOFs) of formulae [Co7(L)3(4,4′-BPy)2(OH)2(H2O)6]·-4 H2O(1) and [Cd2(L)(2,2′-BPy)2]n(2, H4L = 5-(3,5-dicarboxybenzyloxy)-isophthalic acid,2,2′-BPy = 2,2?-bipyridine, 4,4′-BPy = 4,4′-bipyridine) were synthesized under solvothermal conditions. The structures of 1 and 2 were characterized by X-ray single-crystal diffraction analysis.In complex 1, six cobalt atoms were connected by oxygen atoms to form a defect dicubane structure. The defect dicubane structures were further linked by Co(4,4?-BPy) units to generate a3-D network structure. Compound 2 displays a 2-D chain structure. The photoluminescent property of complex 2 is investigated. The results show the exclusive luminescence emission bands being originated from intraligand π-π^* transitions. 展开更多

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

A high-efficiency electro-thermal heater requires simultaneously high electrical and thermal conductivities to generate and dissipate Joule heat efficiently.A low in put voltage is essential to en sure the heaters safe applications.However,the low voltage gen erally leads to low saturated temperature and heati ng rate and hence a low thermal efficie ncy.How to reduce the in put voltage while maintai ning a high electro-thermal efficiency is still a challenge.Herein,a highly electrical and thermal conductive film was 8nstructed using a graphene-based composite which has an internal three-dimensional(3D)conductive network.In the 3D framework,cellulose nanocrystalline(CNC)phase with chiral liquid crystal manner presents in the form of alig ned helix betwee n the graphe ne oxide(GO)layers.Carbon nano dots(CDs)are assembled泊side the composite as con ductive nano fillers.Subseque nt an neali ng and compressi on results in the formati on of the assembled GO-CNC-CDs film.The carb on ized CNC nano rods(CNR)with the helical alignment act as irrplane and through-pla ne conn ecti ons of n eighbori ng reduced GO(rGO)nano sheets,forming a con ductive network in the composite film.The CDs with ultrafast electr ons tran sfer rates provide additi onal electro ns and phonons tran sport paths for the composite.As a result,the obtai ned graphe ne?based composite film(rGO-CNR-CDs)exhibited a high thermal conductivity of 1,978.6 W m^-1·K^-1 and electrical conductivity of 2,053.4 S·cm^-1,respectively.The composite film showed an outstanding electro-thermal heating efficiency with the saturated temperature of 315℃and maximum heating rate of 44.9℃·s^-1 at a very low in put voltage of 10 V.The freestandi ng graphe ne composite film with the delicate nano structure desig n has a great pote ntial to be integrated into electro-thermal devices. 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

To meet the requirements for the mechanical and electrochemical performance for carbon fiber-based (CF-based) composites in the structural lithium ion batteries (SLIBs) application, better CF-Based composites are urgently needed. Herein, we report a novel composite metal organic framework (MOF)-derived ZnCo2 O4/C@carbon fiber via a facile method and subsequent annealing treatment. In this anode,the nano ZnCo2 O4/C coatings wrapped on the surface of CF provide more active sites for electrode reactions and the thin carbon layers give the additional protection. For this material, after 100 cycles, it exhibits excellent cycling stability including high reversible capacity of 463 mAh/g at 50 mA/g, which increases 201% than that of the CF. Thus, this structural anode material exhibits enhanced capacity, high initial columbic efficiency. 展开更多

In this article, Nobel Prize Laureate Joseph Stiglitz argues that the standard macro-economic paradigm has failed not only to predict the crisis but also to provide insights into the design of a regulatory framework that would make a recurrence less likely. He points out that many of the underlying assumptions of the standard paradigm always seemed implausible and many of its predictions, such as those concerning the micro-economic behavior of the constituents (firms and households), are inconsistent with the empirical evidence. He then identifies a number of key modeling challenges, what he views as key ingredients that have to be incorporated in any model that is going to describe economic fluctuations or be the basis of a well-designed regulatory or monetary framework. 展开更多
