Cross-cultural researchers are often confronted by the need to translate instruments from one language to another. In the translation, linguistic equivalence, functional equivalence, cultural equivalence and metric equivalence are factors that need to be considered greatly. This paper examines the translation of cross-cultural research instrument from these points of view, illustrates with examples and puts forward suggestions for incorporating each factor into research studies. 展开更多

The exact calculation of point kinetic parameters is very important in nuclear reactor safety assessment, and most sophisticated safety codes such as RELAP5, PARCS,DYN3D, and PARET are using these parameters in their dynamic models. These parameters include effective delayed neutron fractions as well as mean generation time.These parameters are adjoint-weighted, and adjoint flux is employed as a weighting function in their evaluation.Adjoint flux calculation is an easy task for most of deterministic codes, but its evaluation is cumbersome for Monte Carlo codes. However, in recent years, some sophisticated techniques have been proposed for Monte Carlo-based point kinetic parameters calculation without any need of adjoint flux. The most straightforward scheme is known as the ‘‘prompt method'' and has been used widely in literature. The main objective of this article is dedicated to point kinetic parameters calculation in Tehran research reactor(TRR) using deterministic as well as probabilistic techniques. WIMS-D5B and CITATION codes have been used in deterministic calculation of forward and adjoint fluxes in the TRR core. On the other hand, the MCNP Monte Carlo code has been employed in the ‘‘prompt method''scheme for effective delayed neutron fraction evaluation.Deterministic results have been cross-checked with probabilistic ones and validated with SAR and experimental data. In comparison with experimental results, the relativedifferences of deterministic as well as probabilistic methods are 7.6 and 3.2%, respectively. These quantities are10.7 and 6.4%, respectively, in comparison with SAR report. 展开更多

Farmland weeds are an important part of farmland ecosystems.Research on farmland weeds is one of the major research fields in agricultural ecology.It is of great significance for achieving high yield,high quality and high efficiency in agriculture.In recent years,research on farmland weeds has focused on investigation of weed communities,research on weed seed banks,and research on weed control.These three research directions complement each other.Among them,the investigation work of weed communities and the research of weed seed banks are helpful for us to grasp the occurrence of farmland weeds more accurately and provide references for the control of farmland weeds.This article summarizes the research directions of farmland weeds in recent years(weed community investigation,weed seed bank,weed control)and the research methods used,provide reference value for the follow-up research work of farmland weeds,and provide theoretical support for promoting the development of rural ecological industry and building beautiful villages. 展开更多

Objective:To observe and analyze the application of the bedside rhetorical teaching method in teaching nursing interns.Methods:A total of 64 nursing interns in the gastroenterology department of our hospital from July 2022 to May 2023 were randomly divided into two groups,32 cases in the control group and 32 cases in the intervention group.The control group was given conventional teaching methods,and the intervention group was given the bedside rhetorical teaching method on the basis of the conventional teaching.The differences in the methods of teaching between the two groups were compared after the end of the internship,and there was a statistically significant difference with P<0.05.Results:The scores of the interns in the intervention group were significantly better than those of the control group in theoretical knowledge,communication skills,and case analysis items(P<0.05).Conclusion:The bedside rhetorical teaching method transforms classroom education into bedside teaching,which enables the interns to apply the theoretical knowledge to clinical practice,and has a higher improvement in the three aspects of disease knowledge,communication skills,and case analysis,cultivates the interns’comprehensive clinical skills,and lays a good foundation for the future entry into the nursing field. 展开更多

Since the 1990s, with the in-depth study and understanding of sustainable development, quantitative study of regional sustainable development (RSD) was increasingly hot in China. Based on quantitative study of RSD from Core Periodical in China National Knowledge Infrastructure (1992–2008), statistical analysis on the annual distribution, periodicals distribution and changes of the distribution were made. And from perspectives of social–economic, ecological, systematic and emerging methods, the course, problems and trends of the quantitative study methods on RSD were examined and analyzed to get a clear summary. By the review, the context on the quantitative study of RSD was to be clarified. The study also showed that, primarily, fields involving quantitative study are expanding; second, big progresses and constant development have been made on the systematic method gradually sophisticated, the flourishing ecological method and emerging new methods in the context of cross and integration which has made complex integrated systems a more satisfactory solution; third, the method system has been more multi-angled, and the clues of independent innovation have been observed despite the fact that the introduction of imported method is the main trend. Although many problems exist, multi-scale study, dynamic timeseries study and inter-regional comparative study will be further exploited and increasingly carried out with the progress of spatial information technology, which would boost the development and application of new methods in RSD study. 展开更多

The results of years of dental study serve as the foundation for the practise of medicine and,for that matter,dentistry.Doctors may have their own preferences for techniques and materials,but whether directly or indirectly,their decisions are influenced by systematic reviews and meta-analyses.However,due to poorly conducted or presented research,this very basic foundation may not be reliable.Bias in research is one of several factors that might make study results or research itself unreliable.Bias can be introduced into research at many stages,deliberately or unknowingly.Bias can appear at any point during the research process,even before the study itself begins.There are many biases in research,but some of them are more relevant to dentistry research than others.Because it is said that“eyes see what the mind knows”,it is essential to have a complete understanding of the different types of bias,how and when they get entrenched,and what steps may be taken to prevent or lessen them if they do occur.This comprehensive summary of bias in dentistry research is provided by this synoptic review.The goal is to identify gaps and measures that have been taken-or that should have been taken-by providing both descriptive and evaluative summaries,as well as examples from the literature,when needed. 展开更多
