It ensures quality in training programmes, motivates, and directs students’ learning. Assessment is also used for verification of achievement of objectives of training, feedback to students, licencing, certification, and screening of students for advanced training. It is guided by several principles, including the aims of the assessment (why assess), who to assess, timing (when to assess), what to assess, methods (how to assess), and the criteria for determining the usefulness of the assessment. Objective: To describe the assessment methods used during clinical years of the undergraduate programme at Moi University School of Medicine (MUSOM) and determine the student’s perspectives concerning the comprehensiveness, relevance, objectivity of various assessment methods and challenges faced. Methodology: The study was carried out at MUSOM and a cross-sectional study design was employed. Ten study participants were studied using convenience sampling. Data were collected using an interview guide and was analyzed using content analysis. An informed consent was obtained from the study participants. Results: The methods used during clinical years at MUSOM for assessing knowledge and its applications include multiple-choice questions (MCQ), short answer questions (SAQ), modified essay questions (MEQ), long essay questions (LEQ), and oral exam. Whereas the methods for assessing clinical competence include long case, short cases, objective structured clinical examinations (OSCE), and logbook. Students felt that MCQs were comprehensive, objective, and relevant to the curriculum content. They reported that feedback was not provided after assessments. Conclusion: The assessment methods used at MUSOM during clinical years include MCQ, SAQ, MEQ, LEQ, Short cases, long cases, and OSCE. Students reported varied perceptions of the different assessment methods but favored MCQ and OSCE over other formats for assessing knowledge and clinical skills respectively.展开更多

As a society, we are gradually realizing the role of environmental protection and ecologically-focused construction in promoting sustainable development. As an important method for assessing sustainable development, ecological carrying capacity（ECC） has become a powerful tool for investigating sustainable development and assessing eco-environmental problems. Based on results from a large number of previous studies in this discipline, we summarized and generalized the implications, main assessment methods, and key research domains of ECC. Deficiencies and future trends in ECC research are identified. In terms of implications, ECC can be roughly defined into the perspectives of environmental change, human effects on ecological systems, and holistic ecological systems. The primary assessment methods and models can be classified in accordance with these three perspectives, including ecological footprint method, ecosystem-services-based method, net primary productivity method, situation space method, energetic ecological footprint model, system dynamics model, and coupling model. We compared the advantages and disadvantage of different methods and analyzed their applicable conditions. As ECC research has advanced, related studies have gradually extend to land systems, watershed systems, ecologically vulnerable areas, tourism systems, and urban comprehensive systems, which have solved relevant eco-environmental problems based on ECC assessments. Currently, ECC research lacks a standard definition for the ECC index threshold, research related to dynamic monitoring and early warning, sufficient consideration of scientific and technological drivers, and spatial pattern analyses. Future trends in ECC-related research should provide a large-scale assessment of cross-border areas and ecological vulnerable areas, construct an ecological warning platform, and consistently analyze ECC and regional leading industries.展开更多

Of all of these, the most important is the intensity of hazard factors （risk sources）. In this study, this intensity is uniformly defined by the probability of hazard factors; then a relationship is established between disaster risk intensity and hazard factors. The exceedance probability of various hazard factors, including frequency and timing, scope of wind and rain, and maximum wind and rain of impacting TC cases, are calculated using data from TCs that impacted Shanghai fi＇om 1959-2006. The relationship between disaster situation and risk probability of hazard factors is analyzed, and the indices and model of TC disaster assessment are established based on the results. The process maximum wind speed and maximum daily precipitation are very important in TC-related disaster formation in Shanghai. The results of disaster indices coordinate with the results of the assessment model, and both can show the extent of probability of a TC disaster. Tests using TC data in 2007 and 2008 show that disasters caused by TC Krosa （0716） would be more serious than those by TC Wipha （0713）, and that TC Fung Wong （0808） would have a weak impact. Real-life situations validate these results.展开更多

This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.展开更多

Minimizing the conflict of achieving the different environmental functions is an important challenge for all designers. Achieving a continuous thermal and optical comfort in an internal building space using the same window is an example of this challenge, as they have different requirements that may be sometimes contrary. It should be notable that there are a lot of recent technologies that may be used to find solutions for such a conflict. The Environmental Assessment Methods of Buildings appeared to set the principles of the optimum relation between buildings and their environment, they also could be used to encourage designers to reach the best environmental relations, and award them by main or additional assessment points. The research paper proposes to use the Environmental Assessment Methods of Buildings to assess the building ability of minimizing its environmental functions achievement conflict. This proposal depends on determining the inconsistency assessment items that depend on common building components to be achieved, and then determining the time periods that these items are achieved together within, to indicate the time periods without conflicting. Thus, the paper aims to raise the building environmental value in the assessment when the designer succeeds to minimize the expected conflict of the building environmental functions.展开更多

Because there is considerable uncertainty remaining in the stock assessment of albacore tuna（Thunnus alalunga） in the Indian Ocean due to the limited and low-quality data, we investigate the advantages of a Bayesian method in data-poor stock assessment by using Indian Ocean albacore stock assessment as an example. Eight Bayesian biomass dynamics models with different prior assumptions and catch data series were developed to assess the stock. The results show（1） the rationality of choice of catch data series and assumption of parameters could be enhanced by analyzing the posterior distribution of the parameters;（2） the reliability of the stock assessment could be improved by using demographic methods to construct a prior for the intrinsic rate of increase（r）. Because we can make use of more information to improve the rationality of parameter estimation and the reliability of the stock assessment compared with traditional statistical methods by incorporating any available knowledge into the informative priors and analyzing the posterior distribution based on Bayesian framework in data-poor situations, we suggest that the Bayesian method should be an alternative method to be applied in data-poor species stock assessment, such as Indian Ocean albacore.展开更多

文摘Practical activities are an indispensable piece of science education.As such,assessment of these practical activities is vital for continually enhancing the quality of science instruction.This article presents a tentative framework structured for assessing practical activities in science education.The proposed framework is built upon seven components:engagement and participation,relational thinking,stepwise mastery,contextualization,multidimensional integration,empowerment,and scientific articulacy.The framework might provide science educators with an alternative lens through which to enhance the effectiveness of practical activities,promote student engagement,and better prepare learners for the future.This framework is designed to be additive and complementary to existing assessment approaches and can be adapted and customized to suit specific local contexts and varying grade levels by science educators in the pursuit of excellence in an ever-evolving science education landscape.
文摘In this article,we discuss the article recently published by Zhao et al.This study focused on the intersection of metabolic dysfunction-associated steatotic liver disease(MASLD)and drug-induced liver injury(DILI),two major contributors to the global burden of liver disease.By analyzing clinical characteristics,metabolic parameters,immune profiles,and liver pathology,Zhao et al comprehensively explored how MASLD influences the presentation,severity,and prognosis of DILI.Additionally,this study underscores the importance of structured diagnostic tools,such as the Roussel Uclaf Causality Assessment Method,to accurately assess the causality of DILI within the MASLD population.Although this study provides valuable insights,limitations such as its retrospective design and cohort heterogeneity underscore the need for future prospective research to refine diagnostic approaches and therapeutic strategies.
文摘The idea behind this work is developing an adaptive method for the environmental assessment of buildings, to configure different versions according to the variables affecting them (spatial, temporal and associated with building characteristics) to suit different evaluated projects. This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.
文摘Some building components are responsible for achieving more than one environmental function, these functions are usually of different requirements that can never be done by the same actions, and they are usually connected to changeable internal and external environment characteristics that vary among them. Minimizing the conflict of achieving the different environmental functions is an important challenge for all designers. Achieving a continuous thermal and optical comfort in an internal building space using the same window is an example of this challenge, as they have different requirements that may be sometimes contrary. It should be notable that there are a lot of recent technologies that may be used to find solutions for such a conflict. The Environmental Assessment Methods of Buildings appeared to set the principles of the optimum relation between buildings and their environment, they also could be used to encourage designers to reach the best environmental relations, and award them by main or additional assessment points. The research paper proposes to use the Environmental Assessment Methods of Buildings to assess the building ability of minimizing its environmental functions achievement conflict. This proposal depends on determining the inconsistency assessment items that depend on common building components to be achieved, and then determining the time periods that these items are achieved together within, to indicate the time periods without conflicting. Thus, the paper aims to raise the building environmental value in the assessment when the designer succeeds to minimize the expected conflict of the building environmental functions.
文摘Metals and metalloids（termed as metals in this article）are important constituent elements of the earth＇s crust.A number of metals,if present in excess,are toxic to organisms and therefore they are usually defined as toxic metals.

文摘It is widely recognized that assessments of the status of data-poor fish stocks are challenging and that Bayesian analysis is one of the methods which can be used to improve the reliability of stock assessments in data-poor situations through borrowing strength from prior information deduced from species with good-quality data or other known information. Because there is considerable uncertainty remaining in the stock assessment of albacore tuna（Thunnus alalunga） in the Indian Ocean due to the limited and low-quality data, we investigate the advantages of a Bayesian method in data-poor stock assessment by using Indian Ocean albacore stock assessment as an example. Eight Bayesian biomass dynamics models with different prior assumptions and catch data series were developed to assess the stock. The results show（1） the rationality of choice of catch data series and assumption of parameters could be enhanced by analyzing the posterior distribution of the parameters;（2） the reliability of the stock assessment could be improved by using demographic methods to construct a prior for the intrinsic rate of increase（r）. Because we can make use of more information to improve the rationality of parameter estimation and the reliability of the stock assessment compared with traditional statistical methods by incorporating any available knowledge into the informative priors and analyzing the posterior distribution based on Bayesian framework in data-poor situations, we suggest that the Bayesian method should be an alternative method to be applied in data-poor species stock assessment, such as Indian Ocean albacore.
