This study aims to examine key attributes affecting Airbnb users' satisfaction and dissatisfaction through the analysis of online reviews. A corpus that comprises 59,766 Airbnb reviews form 27,980 listings located in 12 different cities is analyzed by using both Latent Dirichlet Allocation and supervised LDA approach. Unlike previous LDA based Airbnb studies, this study examines positive and negative Airbnb reviews separately, and results reveal the heterogeneity of satisfaction and dissatisfaction attributes in Airbnb accommodation. In particular, the emergence of the topic (...) “guest conflicts” in this study leads to a new direction in future sharing economy accommodation research, which is to study the interactions of different guests in a highly shared environment. The results of topic distribution analysis show that in different types of Airbnb properties, Airbnb users attach different importance to the same service attributes. The topic correlation analysis reveals that home like experience and help from the host are associated with Airbnb users' revisit intention. We determine attributes that have the strongest predictive power to Airbnb users' satisfaction and dissatisfaction through the sLDA analysis, which provides valuable managerial insights into priority setting when developing strategies to increase Airbnb users' satisfaction. Methodologically, this study contributes by illustrating how to employ novel approaches to transform social media data into useful knowledge about customer satisfaction, and the findings can provide valuable managerial implications for Airbnb practitioners.

Yan Xin Life Science Technology-Optimized Caloric Restriction (YXLST-CR) is a unique food abstinence, which suppresses appetite and sensation of hunger while maintaining physiological homeostasis. The authors review the first clinical case study on YXLST-CR, or YXLST-bigu, a 15-day, 24-hour observation in 1987 on a 21-year-old female undergoing YXLST-bigu for several months. The participant took no food or water and conducted normal physical activities. The daily records of body weight, temperature, pulse rate, blood pressure, and daily urine test results showed no (...) abnormalities. Homeostasis was maintained during YXLST-CR. The authors also report serum leptin levels in a group of individuals undergoing YXLST-CR and a control group before and after a 24-hour water-only period. The leptin level prior to the observation for the YXLST-CR group was lower than that for the control group and remained unchanged during the observation, suggesting the possibilities of an established metabolic adaptation.

One recurring criticism of the best interests standard concerns its vagueness, and thus the inadequate guidance it offers to care providers. The lack of an agreed definition of ‘best interests’, together with the fact that several suggested considerations adopted in legislation or professional guidelines for doctors do not obviously apply across different groups of persons, result in decisions being made in murky waters. In response, bioethicists have attempted to specify the best interests standard, to reduce the indeterminacy surrounding medical decisions. (...) In this paper, we discuss the bioethicists’ response in relation to the state's possible role in clarifying the best interests standard. We identify and characterise two clarificatory strategies employed by bioethicists —elaborative and enumerative—and argue that the state should adopt the latter. Beyond the practical difficulties of the former strategy, a state adoption of it would inevitably be prejudicial in a pluralistic society. Given the gravity of best interests decisions, and the delicate task of respecting citizens with different understandings of best interests, only the enumerative strategy is viable. We argue that this does not commit the state to silence in providing guidance to and supporting healthcare providers, nor does it facilitate the abuse of the vulnerable. Finally, we address two methodological worries about adopting this approach at the state level. The adoption of the enumerative strategy is not defeatist in attitude, nor does it eventually collapse into (a form of) the elaborative strategy. (shrink)

Digitalization and advanced technologies are replacing human jobs. Around the world, many people have lost their jobs due to increasing digitalization. Similarly, Chinese expatriates associated with the manufacturing sector in emerging countries such as Vietnam face similar challenges. Therefore, Chinese expatriates need to bring competitiveness in their competencies. This competitiveness brings sustainability to their career. The aim of this study is to investigate the impact of career competencies on career sustainability. Moreover, we test the mediating effect of lifelong learning in (...) the relationship between career competencies and career sustainability. A questionnaire survey approach was used in this study. The target population was the Chinese expatriate managers working at China-invested manufacturing multinational organizations in Vietnam. To estimate the proposed relationships, we use structural equation modeling. The results are confirmed that in the direct relationship career competence has a positive impact on career sustainability. The findings of this study also indicate that career competencies have a positive impact on lifelong learning. Furthermore, outcomes confirmed that lifelong learning has a positive impact on career sustainability. Similarly, results are also confirmed that lifelong learning is positively mediating between career competencies and career sustainability. Therefore, the empirical results of this article identify that lifelong learning has a critical impact on sustainable careers. Specifically, this study is useful for mid-level managers who are associated with multinational organizations. At the end of this article, we also explained the practical implications, limitations, and future research directions. (shrink)

Singapore, a highly affluent island city-state located in Southeast Asia, has increasingly leveraged new assisted reproductive technologies (ART) to overcome its dismal fertility rates in recent years. A new frontier in ART is preimplantation genetic testing (PGT) for polygenic risk scores (PRS) to predict complex multifactorial traits in IVF (in vitro fertilisation) embryos, such as type 2 diabetes, cardiovascular diseases and various other characteristics like height, intelligence quotient (IQ), hair and eye colour. Unlike well-known safety risks with human genome editing, (...) there are negligible risks with PGT-P, because there are no man-made genetic modifications that can be transmitted to future generations. Nevertheless, the current efficacy of using PGT-P to select IVF embryos for either increased or decreased probability of developing specific polygenic traits is still far from certain. Hence, the regulatory safeguards proposed here will be based on the assumption that the efficacy of this new technology platform has already been validated. These include: (1) restricting the application of PGT-P only for prevention of clinically relevant polygenic disease traits, (2) securely blocking patients’ access to the raw genomic DNA sequencing data of their IVF embryos, (3) validating diagnosis of polygenic disease traits in the prospective parents/grandparents of IVF embryos, and restricting PGT-P only for preventing specifically diagnosed polygenic disease traits and (4) mandating rigorous and comprehensive genetic counselling for IVF patients considering PGT-P. There is an urgent and dire need to prevent abuse of the PGT-P technique, as well as protect the interests and welfare of patients if its clinical application is to be permitted in the country.

This is a brief review of the Civics and Moral Education programme currently in use in Singapore schools. The paper offers an appraisal of the rationale provided in policy statements and of selected official and students' workbook descriptions of curricular content, activities and pedagogic theories. It shows that the Civics and Moral Education programme is more a matter of training students to absorb pragmatic values deemed to be important for Singapore to achieve social cohesion and economic success, rather than moral (...) education as the development of intrinsic commitment to and habituation in the practice of values, defended on autonomous moral considerations and not mere national expediency. Whilst educationists would be inclined to take issue with the programme's ultimate stand on values, they might warm to the pedagogy it prescribes in terms of the need for character-building by practice and experience, and also the importance of reasoning in the resolving of disputes and dilemmas.

This paper investigates the consequences of taking seriously the metaphysics of Object-Oriented Ontology, as defined by Graham Harman, in the field of literature. Acutely focusing on just one possible mobilisation and application of the theory, the essay deploys OOO to read two major writers of the late 20th century, Don DeLillo and Murakami Haruki, in novel configurations made possible by applying an Object-Oriented method to the genre of Magic Realism. Using this method, the essay unearths an unarticulated avenue for studying (...) the genre and these authors against established national, cultural, and canonical boundaries in literature, putting into conversation various literary traditions based on formal characteristics found in the texts through OOO’s metaphysics, and suggesting wholly untested paths for literary study in the wake of Object-Oriented philosophies.

With the appearance of mankind, the history of mankind's understanding of the human body itself also began. This long process of development rang with the struggle of two world views. The history of the development of man's understanding of the structure and functions of the human body is the history of the unbroken triumph of materialism over idealism, of the dialectical over the metaphysical. This essay simply takes a preliminary look back at this struggle from several aspects in the hope (...) that it might be of use in promoting a deeper and more systematic study of the question.

Due to the COVID-19 pandemic, most employees face increasing career-related stress, particularly those who work in multinational corporations, because the international travel constraints prevent them from going back to their families. Hence, it is imperative to investigate the critical impact of employees’ occupational burnout on career-related outcomes. In response, this research explores the moderating effect of OB on the relationships between career competencies and career sustainability. To achieve a more comprehensive understanding of relevant issues, we adopted a mixed-method research design (...) that includes both qualitative and quantitative analyses. Findings indicate that all the three dimensions of CCs were positively related to CS; moreover, OB negatively moderated the individual relationships of CC and BC with CS. The main contribution of this study is to enrich the existing career literature by addressing the critical moderating role of OB in the links of CC and BC individually with CS. Practical implications are also discussed in this study. (shrink)

IntroductionClinical ethics committees (CECs) support and enhance communication and complex decision making, educate healthcare professionals and the public on ethical matters and maintain standards of care. However, a consistent approach to training members of CECs is lacking. A systematic scoping review was conducted to evaluate prevailing CEC training curricula to guide the design of an evidence-based approach.MethodsArksey and O’Malley’s methodological framework for conducting scoping reviews was used to evaluate prevailing accounts of CEC training published in six databases. Braun and Clarke’s (...) thematic analysis approach was adopted to thematically analyse data across different healthcare and educational settings.Results7370 abstracts were identified, 92 full-text articles were reviewed and 55 articles were thematically analysed to reveal four themes: the design, pedagogy, content and assessment of CEC curricula.ConclusionFew curricula employ consistent approaches to training. Many programmes fail to provide CEC trainees with sufficient knowledge, skills and experience to meet required competencies. Most programmes do not inculcate prevailing sociocultural, research, clinical and educational considerations into training processes nor provide longitudinal support for CEC trainees. Most CEC training programmes are not supported by host institutions threatening the sustainability of the programme and compromising effective assessment and longitudinal support of CEC trainees. While further reviews are required, this review underlines the need for host organisations to support and oversee a socioculturally appropriate ethically sensitive, clinically relevant longitudinal training, assessment and support process for CEC trainees if CECs are to meet their roles effectively.

Background Supporting physicians in Intensive Care Units s as they face dying patients at unprecedented levels due to the COVID-19 pandemic is critical. Amidst a dearth of such data and guided by evidence that nurses in ICUs experience personal, professional and existential issues in similar conditions, a systematic scoping review is proposed to evaluate prevailing accounts of physicians facing dying patients in ICUs through the lens of Personhood. Such data would enhance understanding and guide the provision of better support for (...) ICU physicians. Methods An SSR adopts the Systematic Evidenced Based Approach to map prevailing accounts of caring for dying patients in ICUs. To enhance the transparency and reproducibility of this process, concurrent and independent use of tabulated summaries, thematic analysis and directed content analysis is adopted. Results Eight thousand three hundred fifty-eight abstracts were reviewed from four databases, 474 full-text articles were evaluated, 58 articles were included, and the Split Approach revealed six categories/themes centered around the Innate, Individual, Relational and Societal Rings of Personhood, conflicts in providing end of life care and coping mechanisms employed. Conclusion This SSR suggests that caring for dying patients in ICU impacts how physicians view their personhood. To resolve conflicts within individual concepts of personhood, physicians use prioritization, reframing and rely on accessible, personalized support from colleagues to steer coping strategies. An adapted form of the Ring Theory of Personhood is proposed to direct timely personalized, appropriate and holistic support. (shrink)

BackgroundThe cognitive level of post-stroke aphasia patients is generally lower than non-aphasia patients, and cognitive impairment affects the outcome of stroke. However, for different types of PSA, what kind of cognitive assessment methods to choose is not completely clear. We investigated the Montreal Cognitive Assessment, the Mini-Mental State Examination, and the Non-language-based Cognitive Assessment to observe the evaluation effect of CI in patients with fluent aphasia and non-fluent aphasia.Methods92 stroke patients were included in this study. Demographic and clinical data of (...) the stroke group were documented. The language and cognition were evaluated by Western Aphasia Battery, MoCA, MMSE, and NLCA. PSA were divided into FA and NFA according to the Chinese aphasia fluency characteristic scale. Pearson’s product–moment correlation coefficient test and multiple linear regression analysis were performed to explore the relationship between the sub-items of WAB and cognitive scores. The classification rate of CI was tested by Pearson’s Chi-square test or Fisher’s exact test.ResultsThe scores of aphasia quotient, MoCA, MMSE, and NLCA in NFA were lower than FA. AQ was positively correlated with MoCA, MMSE, and NLCA scores. Stepwise multiple linear regression analysis suggested that naming explained 70.7% of variance of MoCA and 79.9% of variance of MMSE; comprehension explained 46.7% of variance of NLCA. In the same type of PSA, there was no significant difference in the classification rate. The classification rate of CI in NFA by MoCA and MMSE was higher than that in FA. There was no significant difference in the classification rate of CI between FA and NFA by NLCA.ConclusionMoCA, MMSE, and NLCA can be applied in FA. NLCA is recommended for NFA. (shrink)

It is evident, in the face of the COVID-19 pandemic that has physicians confronting death and dying at unprecedented levels along with growing data suggesting that physicians who care for dying patients face complex emotional, psychological and behavioural effects, that there is a need for their better understanding and the implementation of supportive measures. Taking into account data positing that effects of caring for dying patients may impact a physician’s concept of personhood, or “what makes you, ‘you’”, we adopt Radha (...) Krishna’s Ring Theory of Personhood (RToP) to scrutinise the experiences of physicians working in intensive care units (ICU) using a fictional scenario that was inspired by real events. The impact of death and dying, its catalysts, internal constituents, external factors, dyssynchrony, and buffers, specific to ICU physicians, were identified and explored. Such a framework allows for ramifications to be considered holistically and facilitates the curation of strategies for conflict resolution. This evaluation of the RToP acknowledges the experience and wide-ranging effects it has on ICU physicians. As such, our findings provide insight into their specific needs and highlight the importance of support on a personal and organisational level. Although further research needs to be conducted, the RToP could serve as the basis for a longitudinal assessment tool supported by the use of portfolios or mentorship due to their provision of personalised, appropriate, specific, timely, accessible and long-term support.

Background The use of lengthy, detailed, and complex informed consent forms is of paramount concern in biomedical research as it may not truly promote the rights and interests of research participants. The extent of information in ICFs has been the subject of debates for decades; however, no clear guidance is given. Thus, the objective of this study was to determine the perspectives of research participants about the type and extent of information they need when they are invited to participate in (...) biomedical research. Methods This multi-center, cross-sectional, descriptive survey was conducted at 54 study sites in seven Asia-Pacific countries. A modified Likert-scale questionnaire was used to determine the importance of each element in the ICF among research participants of a biomedical study, with an anchored rating scale from 1 to 5. Results Of the 2484 questionnaires distributed, 2113 were returned. The majority of respondents considered most elements required in the ICF to be ‘moderately important’ to ‘very important’ for their decision making. Major foreseeable risk, direct benefit, and common adverse effects of the intervention were considered to be of most concerned elements in the ICF. Conclusions Research participants would like to be informed of the ICF elements required by ethical guidelines and regulations; however, the importance of each element varied, e.g., risk and benefit associated with research participants were considered to be more important than the general nature or technical details of research. Using a participant-oriented approach by providing more details of the participant-interested elements while avoiding unnecessarily lengthy details of other less important elements would enhance the quality of the ICF.

In this study, we examined the role of culture on early adolescents’ social reasoning about peer exclusion. A total of 80 U.S. and 149 Taiwanese early adolescents independently completed a social reasoning essay about peer exclusion. Analyses of the essays based on social-moral theories showed that U.S. students tended to reason about peer exclusion based on social conventional thinking whereas Taiwanese students were more attentive to personal and moral issues. Despite this difference, both groups of students referred to some common (...) social-moral concepts while reasoning about peer exclusion, including consideration of personal benefit, harming others’ welfare, personal concern, and punishment. The use of social reasoning strategies was similar across the two groups of students except that Taiwanese students relied more on judgment whereas U.S. students generated more alternative hypotheses.

Mathematics is an important foundation for the development of science education. In the past, when instructors taught mathematical concepts of geometry shapes, they usually used traditional textbooks and aids to conduct teaching activities, which resulted in students not being able to understand the principles completely. Nowadays, it has become a trend to integrate emerging technologies into mathematics courses and to use digital instructional aids. Emerging technologies can effectively enhance students’ sensory experience while strengthening their impressions and understandings of subject concepts. (...) In this paper, we apply virtual reality immersive technologies to develop a “virtual reality immersive learning mathematics geometry system,” which is used to teach mathematical geometry concepts. Teachers use the system to develop three basic mathematical geometry learning materials: “Triangular pyramid volume = 1/3 prism volume,” “Cone volume calculation,” and “Triangle center of gravity derivation.” In the experimental activity, the teacher uses virtual reality teaching aids to guide students to learn mathematical geometry concepts in a fun way so that they can achieve the effectiveness of immersive learning. This study explores the impact of using the virtual reality immersive learning mathematics geometry system on students’ technology acceptance, learning motivations, and learning performance. The experimental result showed that using the virtual reality immersive learning mathematics geometry system can improve the learning motivation and learning performance of students. The findings indicated that the experimental group had better learning outcomes after completing the learning tasks of three geometric units. The experimental group used the virtual reality immersive learning mathematics geometry system which can lead to better learning outcomes. According to the ARCS questionnaire, students in the experimental group were confident to understand new subjects. At the same time, the mode of completing the game can effectively give students a sense of accomplishment. The use of emerging technologies in the classroom can be an attractive learning mode for students. (shrink)

BackgroundThe COVID-19 pandemic has changed the healthcare landscape drastically. Stricken by sharp surges in morbidity and mortality with resource and manpower shortages confounding their efforts, the medical community has witnessed high rates of burnout and post-traumatic stress amongst themselves. Whilst the prevailing literature has offered glimpses into their professional war, no review thus far has collated the deeply personal reflections of physicians and ascertained how their self-concept, self-esteem and perceived self-worth has altered during this crisis. Without adequate intervention, this may (...) have profound effects on their mental and physical health, personal relationships and professional efficacy.MethodsWith mentions of the coronavirus pervading social media by the millions, this paper set out to collate and thematically analyse social media posts containing first-person physician reflections on how COVID-19 affected their lives and their coping mechanisms. A consistent search strategy was employed and a PRISMA flowchart was used to map out the inclusion/exclusion criteria.ResultsA total of 590 social media posts were screened, 511 evaluated, and 108 included for analysis. Salient themes identified include Disruptions to Personal Psycho-Emotional State, Disruptions to Professional Care Delivery, Concern for Family, Response from Institution, Response from Society and Coping Mechanisms.ConclusionIt is evident that the distress experienced by physicians during this time has been manifold, multi-faceted and dominantly negative. Self-concepts were distorted with weakened self-esteem and perceived self-worth observed. The Ring Theory of Personhood (RToP) was adopted to explain COVID-19’s impact on physician personhood as it considers existential, individual, relational and social concepts of the self. These entwined self-concepts serve as ‘compensatory’ to one another, with coping mechanisms buffering and fortifying the physician’s overall personhood. With healthcare institutions playing a vital role in providing timely and targeted support, it was further proposed that a comprehensive assessment tool based on the RToP could be developed to detect at-risk physicians and evaluate the presence and effectiveness of established support structures.

This study aimed at exploring the impact of post-epidemic era on teachers’ behavioral intention of distance education. In this study, purposive sampling method was used to enroll 390 teachers in colleges and universities, high schools and vocational schools, and junior high and elementary schools to be the research subjects for the questionnaire survey. A total of 360 questionnaires were collected for statistics, and AMOS 23.0 statistical software was used to analyze the correlation between variables. Meanwhile, a structural equation model was (...) used to analyze and verify the impact of the technology acceptance model, information system success model, and diffusion of innovations theory. According to the results, the system quality of distance teaching platforms certainly affected perceived usefulness, and perceived usefulness affected teachers’ attitudes toward using distance teaching systems. In addition, perceived ease of use had an impact on perceived usefulness, and trialability had an impact on teachers’ attitudes toward using distance teaching systems. Finally, teachers’ attitude toward using a distance teaching system also affected their behavioral intention. According to the results, suggestions were made in this study to teachers and students for distance teaching. Additionally, the main contribution of this study lies in providing specific strategies for further distance teaching through empirical results in combination with on-site teaching. (shrink)

BackgroundAmidst expanding roles in education and policy making, questions have been raised about the ability of Clinical Ethics Committees (CEC) s to carry out effective ethics consultations (CECons). However recent reviews of CECs suggest that there is no uniformity to CECons and no effective means of assessing the quality of CECons. To address this gap a systematic scoping review of prevailing tools used to assess CECons was performed to foreground and guide the design of a tool to evaluate the quality (...) of CECons.MethodsGuided by Levac et al’s (2010) methodological framework for conducting scoping reviews, the research team performed independent literature reviews of accounts of assessments of CECons published in six databases. The included articles were independently analyzed using content and thematic analysis to enhance the validity of the findings.ResultsNine thousand sixty-six abstracts were identified, 617 full-text articles were reviewed, 104 articles were analyzed and four themes were identified – the purpose of the CECons evaluation, the various domains assessed, the methods of assessment used and the long-term impact of these evaluations.ConclusionThis review found prevailing assessments of CECons to be piecemeal due to variable goals, contextual factors and practical limitations. The diversity in domains assessed and tools used foregrounds the lack of minimum standards upheld to ensure baseline efficacy.To advance a contextually appropriate, culturally sensitive, program specific assessment tool to assess CECons, clear structural and competency guidelines must be established in the curation of CECons programs, to evaluate their true efficacy and maintain clinical, legal and ethical standards.

Social media users have increased rapidly in recent years; however, most are “silent users” who rarely share information online. To maintain social media companies’ stable operation and development, this research explored the effects of flow experience and identity formation on users’ intrinsic motivation to facilitate aggressive, spontaneous, and habitual participation in virtual communities. A total of 487 valid questionnaires were collected and underwent regression analysis. The results revealed that all three intrinsic motivations had a significant impact on social media participation, (...) with social interaction exerting the strongest influence. Flow experience and identification had significant, partial mediating effects on the relationship between motivation and participation. Several suggestions were provided based on the results to help social media enterprises increase user participation. It is hoped that this research could facilitate in transforming users into habitual participants to keep the operations of the virtual community stable and enduring. (shrink)

Embedded in the Daodejing and the Zhuangzi is a unique concept that lends itself to the formulation of a distinct system of ethics. The distinctiveness that wu-wei infuses into the realm of ethics resides in its principal constituent, spontaneity. Implicit in wu-wei is spontaneity and its dialectical opposite, the nonspontaneous elements that are essential to the integrity of any system of ethics. This paper attempts to bring to the fore this implicit dialectic of spontaneity and non spontaneity through wu-wei's relation (...) to the Dao as harmony of opposites, its imperative of enlightened response, and its congeniality to the case for libertarianism.
