Normal levels for the five vital signs are published by the American Heart Association, and other specialty organizations, however, the sixth vital sign (resilience) which adopts the measure of immune resilience is suggested in this paper. Resilience is the ability of the immune system to respond to attacks and defend effectively against infections and inflammatory stressors, and psychological resilience is the capacity to resist, adapt, recover, thrive, and grow from a challenge or a stressor. Individuals with better optimal immune resilience had better health outcomes than those with minimal immune resilience. The purpose of this paper is to conceptualize, contextualize, and operationalize all six vital signs. We suggest measuring resilience subjectively and objectively. Subjectively, use a 5-item guided interview revised from the Connor-Davidson Resilience Scale (CDRC), a scale of 10 items. The revised CDRC scale is a 5-item scale. The scale is rated on a 5-point Likert scale from 0 (not true) to 4 (true all the time). The total score ranges from 0 to 20, with higher total scores indicating greater resilience. The scale demonstrated good construct validity and internal consistency (α = 0.85) during the development of the scale. The CD-RISC had a good Cronbach’s alpha level of 0.85. The Revised CD-RISC can be completed in 2 - 4 minutes. To measure resilience objectively, we suggest using Immune Resilience (IR) levels, the level of resilience to preserve and/or rapidly restore immune resilience functions that promote disease resistance and control inflammation and other inflammatory stress. IR levels are gauged with two peripheral blood metrics that quantify the balance between CD8 and CD4 T-cell levels and gene expression signatures tracking longevity-associated immunocompetence and mortality- or entropy-associated inflammation. IR deregulation is potentially reversible by decreasing inflammatory stress. IR metrics and mechanisms have utility as vital signs and biomarkers for measuring immune health and improving health outcomes.展开更多

But these terms can generally be distinguished by two different categories of study as some experts have emphasized that the above developments are in the process （Globalization） while the others considered them on the project （To Globalize）. The main problem is that how we can find out the focal point of both studies through which the accuracy of these claims to be verified to know whether contemporary changes and evolutions are formed in a process or a project. It seems that the focal point in the sphere of both claims （processes and projects） is the issue of ＂identity＂ since both spheres agree that the concept of ＂identity＂ has passed a series of changes and developments, although each one renders the path and goal of ＂identity＂ changes by its own specific interpretations. In this article, we claim that using linguistic approach we are able to review the developments and evolutions＇ flow of identity in the present era and thereby it can be found that the developments in information and communication would lead to creating a process in the context of Globalization or a project on Universalization. The assumption of this study is that by explanation of the above-mentioned situation, we can see that based on the linguistic approach, the process of making identity is ＂context-based＂ and ＂conditional＂ as opposed to a project view formation and relative continuity of identification process would generally be subject to the condition.展开更多

Linguistics can provide language teaching with theories and language teaching can further prove the validity of linguistics. To some extent, linguistics is more theoretical while language teaching is more practical. Since linguistics is defined as the scientific study of language, it seems obvious that such a study would have direct relations to language teaching. This paper attempts to make an analysis of difference between Contextual theory of meaning and the teaching of EFL reading.展开更多

文摘Purpose:Strong primary health care(PHC)systems require well‐established PHC education systems to enhance the skills of general practitioners(GPs).However,the literature on the experiences of international collaboration in primary care education in low‐and middle‐income countries remains limited.The purpose of this study was to evaluate the implementation and perceived impact of the McGill‐Tongji Blended Education Program for Teacher Leaders in General Practice(referred to as the“Tongji Program”).Methods:In 2020–2021,the McGill Department of Family Medicine(Montreal,Canada)and Tongji University School of Medicine(TUSM,Shanghai,China)jointly implemented the Tongji Program in Shanghai,China to improve the teaching capacity of PHC teachers.We conducted an exploratory longitudinal case study with a mixed methods design for the evaluation.Quantitative(QUAN)data was collected through questionnaire surveys and qualitative(QUAL)data was collected through focus group discussions.Results:The evaluation showed that learners in Tongji Program were primarily female GPs(21/22,95%)with less than 4 years of experience in teaching(16/22,73%).This program was considered a successful learning experience by most participants(19/22,86%)with higher order learning tasks such as critical thinking and problem‐solving.They also agreed that this program helped them feel more prepared to teach(21/22,95%),and developed a positive attitude toward primary care(21/22,95%).The QUAL interview revealed that both the Tongji and McGill organizers noted that TUSM showed strong leadership in organization,education,and coordination.Both students and teachers agreed that by adapting training content into contextualized delivery formats and settings,the Tongji Program successfully overcame language and technology barriers.Conclusions:Committed partnerships and contextualization were key to the success of the Tongji Program.Future research should focus on how international primary care education programs affect learners'behavior in their practice settings,and explore barriers and facilitators to change.

文摘As e-commerce continues to mature,the advantages of live streaming within the industry have become increasingly apparent,offering significant growth opportunities.Social e-commerce platforms,which are user-centered,integrate social networks with e-commerce by leveraging social interactions to drive product sales and enhance the overall consumer shopping experience.This type of e-commerce fosters engagement and promotes products by merging online communities with shopping behavior,creating a more interactive and dynamic marketplace.It not only retains the traditional e-commerce trading and marketing functions but also adds a social dimension,making live stream anchors crucial figures connecting consumers with products.These anchors can attract consumers with their appearance and charm,and use their expertise on live streaming platforms to guide consumers by recommending live content.They can also interact with their audiences and potentially influence them to purchase the recommended goods.It is evident that the attributes of anchors in live streaming rooms significantly impact consumers’online behavior.Therefore,researching how platform contextual factors regulate consumers’online behavior is of great practical significance.This study employs multilevel regression analysis to support its hypotheses using data.The findings indicate that contextual factors of the platform significantly influence online behavior,enhancing the positive relationship between user attachment and online activities.
文摘Communicational and international developments have different aspects in today＇s world so that some terms like ＂Internationalization,＂ ＂Liberalization,＂ ＂Universalization,＂ ＂Westernization,＂ ＂Deterritorialization＂ find interferences in social sciences and humanities studies. But these terms can generally be distinguished by two different categories of study as some experts have emphasized that the above developments are in the process （Globalization） while the others considered them on the project （To Globalize）. The main problem is that how we can find out the focal point of both studies through which the accuracy of these claims to be verified to know whether contemporary changes and evolutions are formed in a process or a project. It seems that the focal point in the sphere of both claims （processes and projects） is the issue of ＂identity＂ since both spheres agree that the concept of ＂identity＂ has passed a series of changes and developments, although each one renders the path and goal of ＂identity＂ changes by its own specific interpretations. In this article, we claim that using linguistic approach we are able to review the developments and evolutions＇ flow of identity in the present era and thereby it can be found that the developments in information and communication would lead to creating a process in the context of Globalization or a project on Universalization. The assumption of this study is that by explanation of the above-mentioned situation, we can see that based on the linguistic approach, the process of making identity is ＂context-based＂ and ＂conditional＂ as opposed to a project view formation and relative continuity of identification process would generally be subject to the condition.
文摘Both linguistics and language teaching take language as their subject. Linguistics can provide language teaching with theories and language teaching can further prove the validity of linguistics. To some extent, linguistics is more theoretical while language teaching is more practical. Since linguistics is defined as the scientific study of language, it seems obvious that such a study would have direct relations to language teaching. This paper attempts to make an analysis of difference between Contextual theory of meaning and the teaching of EFL reading.
