Preceptors'experiences in guiding nursing students to use research findings and to implement evidence-based practice

Objective:Evidence-based practices(EBPs)have been taught to students by identifying the best evidence/evidence from research results.However,the experiences of Indonesian nurse preceptors in helping students implement research findings have not been explored thoroughly.This study aimed to explore Indonesian nurse preceptors in guiding nursing students to use research findings.Methods:This study used interpretive phenomenology analysis that involves 9 nurse preceptors from hospitals in West Kalimantan,Indonesia.Semi-structured in-depth interviews were recorded and then transcribed verbatim.Results:Three themes were generated during the analysis:“types of student supervision,”“issues during supervision,”and“the need for research literacy and supervision.”Conclusions:Nurse preceptors need support to supervise the nursing students to use research findings.In addition to upgrading nursing skills,nurse preceptors must receive training in research and its utilization.Developing an appropriate strategy to assist students in using research findings will enhance the promotion of evidence-based nursing practices on a daily basis.

The Black American Church: A Reactionary and Ideological Apparatus of Slavery

This work argues that Denmark Vesey,Nat Turner,Gabriel Prosser,David Walker,Henry Highland Garnet,amongst a few others were the reactionary(dialectical)exceptions to the black church,not the norm,an(ideological)institution established to interpellate and indoctrinate blacks to accept their conditions in slavery.In other words,the aforementioned were the enslaved who used Christian dogma to(negative dialectically)respond to the barbarity of slavery by violently convicting white Christian society for not living up to its values,ideas,and ideals given the treatment of African people by so-called Christians.In the latter sense it was reactionary;in the former,it was an ideological apparatus of domination and control for the institution of slavery.The contemporary attempt to racially vindicate the black church as a sui generis revolutionary institution overflowing with Africanisms is ahistorical and ideological reaped in pseudoscientific propositions stemming from postmodern and post-structural theories.

Epoché as the Breakthrough of the Natural Attitude

The following contribution aims to interpret the methodical device of Husserl’s epochéin light of the concept of breakthrough.Since the epochéis a theoretical device directed towards the suspension of the natural attitude,I will first attempt to define the concept of natural attitude.Subsequently,I will seek to understand the rich meaning of the concept of epoché.Finally,I will explore how this element is related to the concept of breakthrough.In other words,I will endeavour to clarify how the epochédetermines a breakthrough of the natural attitude,which is not to be understood as“annihilation”or“destruction”but as a traversal.

Exploring the meaning of care among lived experiences of patients with blindness:an interpretive phenomenological study

Objective:To explore the meaning of care experienced by people with blindness in hospitals.Methods:Interpretive phenomenology along with the 6-step method of van Manen was used to conduct the study.Using purposeful sampling,15 people with legal blindness were interviewed.Thematic analysis was used to isolate the meaning of care.Results:Five themes emerged:(a)nurses in the eyes of patients with blindness;(b)negligence in the caring moments;(c)being cared for in ambiguity;(d)Uncoordinated care;and(e)Psychological discomfor t.These sub-themes were condensed into an overarching theme titled as“marginalized patients inside the stereotypical healthcare system.”Conclusions:Lived experiences of patients with blindness revealed that hospitals provide stereotypic or inappropriate care for this minority group in society.Health professionals par ticularly nurses should be skilled to provide person-centered and coordinated care for patients with blindness.

初探宗教现象学

宗教现象学是当代西方文化中使用现象学方法来诠释宗教的一种学说,它在理论上与传统宗教的理性实体学说和自然神学理论相区别,一是将宗教的论证方式由外在实体出发转向由人的直观意识出发,二是将对神的论证由理性论证的途径改变为意识直观和生存体验的途径。宗教现象学把人的直观意识体验和生存感受作为其理论的出发点,它同时把宗教理解为前导入的生存的意义纲领。宗教现象学跨越了现象学、存在主义、解释学、心理学、人类学及神学等多个学科,尚有许多理论问题有待进一步澄清。

Differences of Phenomenological Reduction and Fusion of Horizons in Analyzing Literary Works——Analysis of Hawthorne's Young Goodman Brown from the Perspectives of Phenomenological Reduction and Fusion of Horizons

Edmund Husserl's first important move about phenomenology is the"phenomenological reduction"which means that we should reduce the external world to the contents of our consciousness alone. However, Hans-Georg Gadamer holds the opinion that all interpretation of a past work consists in a dialogue between past and present(Eagleton, T. 2009:62). Gadamer's famous theory is fusion of horizons which means that the event of understanding comes about when our own"horizon"of historical meanings and assumptions"fuses"with the"horizon"within which the work itself is placed. The present thesis takes Hawthorne's YoungGoodmanBrown as an example to illustrate different understandings when readers apply the two different theories.

Prediction on hot deformation behavior of spray-formed 7055 aluminum alloy via phenomenological models

Hot compression tests in the temperature range of 340-450 ℃ and strain rate range of 0.001-1 s^-1 of spray-formed 7055 aluminum alloy were carried out to study its hot deformation behavior. Three phenomenological models including Johnson-Cook, modified Fields-Backofen and Arrhenius-type were introduced to predict the flow stresses during the compression process. And then, a comparative predictability of the phenomenological models was estimated in terms of the relative errors, correlation coefficient（R）, and average absolute relative error（AARE）. The results indicate that Johnson-Cook model and modified Fields-Backofen model cannot well predict the hot deformation behavior due to the large deviation in the process of line regression fitting. Arrhenius-type model obtains the best fit through combining the effect of strain rate and temperature.

Phenomenological Anisotropic Study of Surface Finish in Pack Rolling

A phenomenological anisotropic model has been presented for the surface roughness modeling of pack rolling. The model is an assembly of grains in different orientations and sizes. The grain size is assumed to be in log-normal distribution. To model the macro anisotropic mechanical behavior of the grains induced by the slip deformation, the grains are assumed as isolated anisotropic units. The units have different mechanic behavior, and depend on the crystallographic orientations and the external loading as well as the interaction of the adjunctive grains. In the paper, the material properties of the grains are assumed as uniform distributions. The roughness of the contact surfaces depends on the distribution types and the scatters of the distributions. It is found that the initial roughness of the contact surfaces has a little influence on the surface roughness when the rolling deformation is large. The comparison between the phenomenological model and crystallographic model shows that the phenomenological model can also give out a reasonable result, while it only takes much less CPU time. The agreement between the single sheet model and the pack rolling model shows that in a certain degree the pack rolling model can be replaced by the single sheet model to decrease the CPU time.

A comparative study of 85 hyperelastic constitutive models for both unfilled rubber and highly filled rubber nanocomposite material

Nonlinear finite element analysis is widely used for structural optimization of the design and the reliability analysis of complex elastomeric components.However,high-precision numerical results cannot be achieved without reliable strain energy functions(SEFs)of the rubber or rubber nanocomposite material.Although hyperelastic constitutive models have been studied for nearly 80 years,selecting one that accurately describes rubber's mechanical response is still a challenge.This work reviews 85 isotropic SEFs based on both the phenomenological theory and the micromechanical network theory proposed from the 1940s to 2019.A fitting algorithm which can realize the automatic fitting optimization and determination of the parameters of all SEFs reviewed is developed.The ability of each SEF to reproduce the experimental data of both the unfilled and highly filled rubber nanocomposite is quantitatively assessed based on a new proposed evaluation index.The top 30 SEFs for the unfilled rubber and the top 14 SEFs for the highly filled rubber nanocomposite are presented in the ranking lists.Finally,some suggestions on how to select an appropriate hyperelastic constitutive model are given,and the perspective on the future progress of constitutive models is summarized.

A qualitative study on the experiences and attributions for resigned nurses with career plateau

Objectives:This study seeks to understand the experiences of nurses who resigned because of limited available career development opportunities and of the possible reasons for their resignation.Methods:Semi-structured interviews were conducted with nine clinical nurses who experienced limitations in the development of their careers and consequently left their jobs to elicit their feelings and reasons for leaving.The content analysis was used to analyze the interview data.Results:Two themes and four subthemes relating to the experiences and attributions of former nurses were identified.Nurses who experienced career plateau were disappointed with the current work and uncertainty about the future.The attribution of career plateau lies in unsatisfied personal needs and the absence of organizational support.Conclusions:Nurses had strong career plateau experiences before they left,and it caused a series of negative feelings in their practice.Establish a clear career development path and multi-dimensional support from the organization may be helpful to reduce the occurrence of career plateau,thus increasing the retention of nurses.

Differential diagnosis of obsessive-compulsive symptoms from delusions in schizophrenia: A phenomenological approach

Several studies suggest increased prevalence-rates of obsessive-compulsive symptoms(OCS) and even of obsessive-compulsive disorder(OCD) in patients with schizophrenic disorders. Moreover, it has been recently proposed the existence of a distinct diagnostic subgroup of schizo-obsessive disorder. However, the further investigation of the OCS or OCD-schizophrenia diagnostic comorbidity presupposes the accurate clinical differential diagnosis of obsessions and compulsions from delusions and repetitive delusional behaviours, respectively. In turn, this could be facilitated by a careful comparative examination of the phenomenological features of typical obsessions/compulsions and delusions/repetitive delusional behaviours, respectively. Thiswas precisely the primary aim of the present investigation. Our examination included seven features of obsessions/delusions(source of origin and sense of ownership of the thought, conviction, consistency with one's belief-system, awareness of its inaccuracy, awareness of its symptomatic nature, resistance, and emotional impact) and five features of repetitive behaviours(aim of repetitive behaviours, awareness of their inappropriateness, awareness of their symptomatic nature, and their immediate effect on underlying thought, and their emotional impact). Several of these clinical features, if properly and empathically investigated, can help discriminate obsessions and compulsive rituals from delusions and delusional repetitive behaviours, respectively, in patients with schizophrenic disorders. We comment on the results of our examination as well as on those of another recent similar investigation. Moreover, we also address several still controversial issues, such as the nature of insight, the diagnostic status of poor insight in OCD, the conceptualization and differential diagnosis of compulsions from other categories of repetitive behaviours, as well as the diagnostic weight assigned to compulsions in contemporary psychiatric diagnostic systems. We stress the importance of the feature of mental reflexivity for understanding the nature of insight and the ambiguous diagnostic status of poor insight in OCD which may be either a marker of the chronicity of obsessions, or a marker of their delusionality. Furthermore, we criticize two major shortcomings of contemporary psychiatric diagnostic systems(DSM-IV, DSM-V, ICD-10) in their criteria or guidelines for the diagnosis of OCD or OCS: first, the diagnostic parity between obsessions and compulsions and, second, the inadequate conceptualization of compulsions. We argue that these shortcomings might artificially inflate the clinical prevalence of OC symptoms in the course of schizophrenic disorders. Still, contrary to a recent proposal, we do not exclude on purely a priori grounds the possibility of a concurrence of genuine obsessions along with delusions in patients with schizophrenia.

Effect of curing, capillary action, and groundwater level increment on geotechnical properties of lime concrete: Experimental and prediction studies

Lime concrete and lime treatment are two attractive techniques for geotechnical engineers.However,researches have rarely been carried out to study the effects of moisture and capillary action due to increasing groundwater level on geotechnical properties of lime concrete.The aim of this study is to investigate the effects of curing time and degree of saturation on some of geotechnical properties of lime concrete such as unconfined compressive strength(UCS),secant modulus(ES),failure strain,brittleness index(IB),and deformability index(ID) using unconfined compression tests.First of all,geotechnical and chemical properties of used materials were determined.After curing times of 14 d,28 d,45 d,and 60 d in laboratory condition,the specimens were exposed to saturation levels ranging from 0 to 100%.The results showed that the moisture and curing time have significant effects on the properties of lime concrete.Based on the results of scanning electron micrograph(SEM) test,it was observed that the specimen was characterized by a rather well-structured matrix since both the filling of a large proportion of the coarse-grained soil voids by clay and the pozzolanic activity of lime led to retaining less pore water in the specimen,increasing the UCS and ES,and consequently resisting against swelling and shrinkage of the clay soil.Moreover,due to the pozzolanic reactions and reduction of water,by increasing the curing time and decreasing the degrees of saturation,UCS,ES,and IBincreased,and IDdecreased.Based on the experimental results,a phenomenological model was used to develop equations for predicting the properties in relation to the ratio of degree of saturation/curing time.The results showed that there was a good correlation(almost R2> 90%) between the measured parameters and the estimated ones given by the predicted equations.

Microstructure and mechanical properties of in-situ TiB_2/A356 composites and a prediction model of yield strength

The in-situ TiB2/A356 composites were successfully synthesized through the mixed salt reaction method. The advantage of this technique was that the particle sizes and morphology can be controlled by the melt reaction. Therefore, the technique can be designed to obtain expected properties, such as high strength at high and room temperatures, high damping capacity, high modulus and good fatigue life. Results showed that in the as-cast state of A356 alloy and TiB2/A356 composites, the eutectic Si phase is normally in the needle shape, and TiB2 particles are mostly in the cubic or near spherical shape, with the size ranging from 30 to 500 nm uniformly distributed in the grains. Also, TiB2 particle clusters are observed in composites. With an increase in TiB2 particles, the average grain size of composites decreases both in as-cast and T6 state. It is found that both the yield stength and ultimate tensile strength increase with an increase in the TiB2 volume fraction. On the contrary, the elongation reduces with the addition of TiB2 particles. Based on the experimental results and Clyne＇s report, a revised model related to particle strengthening mechanism was proposed to fairly predict yield strengths of TiBJA356 composites. The satisfactory agreement between the calculated values and experimental data reported in the literature was obtained.

Phenomenology of plume-surface interactions and preliminary results from the Tianwen-1 landing crater on Mars

The plume-surface interaction(PSI)is a common phenomenon that describes the environment surrounding the landers resulting from the impingement of hot rocket exhaust on the regolith of planetary bodies.The PSI will cause obscuration,erosion of the planetary surface,and high-speed spreading of dust or high-energy ejecta streams,which will induce risks to a safe landing and cause damage to payloads on the landers or to nearby assets.Safe landings and the subsequent scientific goals of deep-space exploration in China call for a comprehensive understanding of the PSI process,including the plume flow mechanics,erosion mechanism,and ejecta dynamics.In addition,the landing crater caused by the plume provides a unique and insightful perspective on the understanding of PSI.In particular,the PSI can be used directly to constrain the composition,structure,and mechanical properties of the surface and subsurface soil.In this study,we conducted a systematic review of the phenomenology and terrestrial tests of PSI:we analyzed the critical factors in the PSI process and compared the differences in PSI phenomena between lunar and Martian conditions;we also reviewed the main erosion mechanisms and the evolution and development of terrestrial tests on PSI.We discuss the problems with PSI,challenges of terrestrial tests,and prospects of PSI,and we show the preliminary results obtained from the landing crater caused by the PSI of Tianwen-1.From analysis of the camera images and digital elevation model reconstructions,we concluded that the landing of Tianwen-1 caused the deepest crater(depth>40 cm)on a planetary surface reported to date and revealed stratigraphic layers in the subsurface of Martian soil.We further constrained the lower bounds of the mechanical properties of Martian soil by a slope stability analysis of the Tianwen-1 landing crater.The PSI may offer promising opportunities to obtain greater insights into planetary science,including the subsurface structure,mineral composition,and properties of soil.

In silico studies of magnesium-based implants: A review of the current stage and challenges

In silico methods to study biodegradable implants have recently received increasing attention due to their potential in reducing experimental time and cost. An important application case for in silico methods are magnesium(Mg)-based biodegradable implants, as they represent a powerful alternative to traditional materials used for temporary orthopaedic applications. Controlling Mg alloy degradation is critical to designing an implant that supports the bone healing process. To simulate different aspects of this biodegradation process, several mathematical models have been proposed with the ultimate aim of replacing laboratory experiments with computational modeling. In this review, we provide a comprehensive and critical discussion of the published models and their performance with respect to capturing the complexity of the biodegradation process. This complexity is presented initially. Additionally, the present review discusses the different approaches of optimizing and quantifying the different sources of errors and uncertainties within the proposed models.

Phenomenological description of semi-soft nematic elastomers

Nematic elastomers are new materials that have many remarkable properties.In this article,we study how nonlinear elasticity of semi-soft nematic elastomers can be described phenomenologically.We start with a theory based on strain tensor only,and then continue to develop a phenomenological description with the liquid crystal order tensor included explicitly.Such a description has the virtue of being able to treat the strain tensor and the liquid crystal order tensor equally and thus making the complicated symmetries of nematic elastomers easier to understand.

General solution model and its new progress

The physicochemical properties of multicomponent systems are involved in all fields of chemistry and have received attention from various related areas such as minerals,metallurgy,material science,environment,biology,and agriculture.At present,the relevant data can be obtained by using two major calculation methods,namely,the first principle method and the empirical method.Though the former has achieved recent great progress,it is still a long way to offer practical data;while the latter has not received progress for almost half a century.Therefore,a new method that is theoretically reasonable and accurate in practical application is necessary to obtain practical and precise physicochemical data for ternary and multicomponent systems.In this paper,a new theoretical model is suggested based on its corresponding binary ones.The feasibility of this theoretical model is discussed in terms of both theoretical analysis and practical performance.
