Evidence suggests that English speakers use pronouns when referring to the grammatical subject and predictable thematic role. We tested how grammatical role and thematic role predictability affect different types of referential forms, namely, overt pronouns and null pronouns in Mandarin Chinese. We found that both overt and null pronouns were sensitive to grammatical role. However, we did not find any evidence that overt and null pronouns were sensitive to thematic role predictability. Although null pronouns were influenced by grammatical role, the (...) rate of null pronouns for subject reference was very low compared to that of overt pronouns. Given the frequent occurrence of null pronouns in Mandarin, our results suggest that the use of null pronouns may not be explained by a simple grammatical role mechanism. (shrink)

Objective: To systematically analyze the effectiveness of technology-based interventions for reducing loneliness in older adults.Methods: We searched relevant electronic databases from inception to April 2021, which included Cochrane Library, PubMed, Web of Science, SpringerLink, EMBASE, CNKI, and Wanfang. The following criteria were used: study design—randomized controlled trial designs, people—older adults, intervention—technology-based interventions in which a core component involved the use of technology to reduce loneliness in older adults; and outcome—reduction of loneliness level in terms of rating scale scores. Two reviewers (...) independently identified eligible studies, extracted data, and assessed the risk of bias in the included studies. A third reviewer resolved any conflicts. The Cochrane Collaboration's bias assessment tool was used to evaluate the risk of bias for the included studies, and Review Manager 5.4 software was used for the meta-analysis. A random effects model was adopted to measure estimates of loneliness reduction, and standard mean differences with a 95% confidence interval were calculated for each intervention-control contrast, and the I2 statistic was applied to examine heterogeneity.Results: A total of 391 participants from six RCTs were included in the review. Of these, three studies were rated as low-quality, and the remaining three were rated as moderate-quality studies. The meta-analysis showed that the evidence regarding the effects on loneliness of technology-based interventions compared with control groups was uncertain, and suggested that technology-based interventions resulted in little to no difference in loneliness reduction compared to control groups. Two types of technology-based interventions were identified: smartphone-based video calls and computer-based training with Internet usage. The subgroup analysis found low-quality evidence to support the effectiveness of both intervention types.Conclusions: We found no current evidence to support that technology-based interventions were effective compared to different control conditions in reducing loneliness in older adults. This suggests that more research is needed to investigate the effects of technology-based interventions on loneliness in older adults. (shrink)

In sexually reproducing organisms maintenance of germ stem cell immortality is fundamental for transmitting genetic material to future generations. While previous research has mainly considered intrinsic regulatory mechanisms in the germline, our recent study has found a direct contribution of somatic cells in preserving germline immortality via the somatically expressed endoribonuclease ENDU‐2 in Caenorhabditis elegans. We have identified ENDU‐2 as a secreted protein that can be taken up by the germline. Here, we discuss how ENDU‐2 might uncouple its RNA‐binding and (...) RNA‐cleavage activities to control gene expression via either an endoribonuclease dependent or an independent way. We also speculate on a possible functional conservation of its mammalian homologs in mediating cell‐cell communication as well as its potential significance in understanding human pathogenesis such as cancer development.

Previous studies have reported that general or photo-specific social media use was associated with women’s body dissatisfaction and body image disturbance. The current study replicated and expanded upon these findings by identifying the positive association between social media influencer viewing and intentions to change appearance. This study surveyed a sample of 7,015 adult female TikTok users in China regarding their social media influencer viewing frequency, self-objectification, social comparison tendencies when watching short videos, intentions to change appearance, and demographics. The results (...) showed that female TikTok users’ self-objectification mediated the association between their influencer viewing frequency and their intentions to change appearance. Furthermore, social comparison tendencies moderated the association between influencer viewing and intentions to change appearance in that the proposed association was stronger for female TikTok users who had lower social comparison tendencies when watching short videos, compared to female TikTok users who had higher social comparison tendencies. The counter-intuitive finding on social comparison tendencies indicated that women who have higher social comparison tendencies may be more aware of the negative influences and adjust their expectations. The observed association between social media influencer viewing and intentions to change appearance was statistically significant but trivial in terms of effect size. Although the result could warn policymakers and practitioners to design media and health literacy campaigns to cultivate body positivity, caution should be exercised when evaluating the practical implications.

This study examined factors including health-related anxiety, preexisting misinformation beliefs, and repeated exposure contributing to individuals’ acceptance of health misinformation. Through a large-scale online survey, this study found that health-related anxiety was positively associated with health misinformation acceptance. Preexisting misinformation beliefs, as well as repeated exposure to health misinformation, were both positively associated with health misinformation acceptance. The results also showed that demographic variables were significantly associated with health misinformation acceptance. In general, females accepted more health misinformation compared to males. (...) Participants’ age was negatively associated with health misinformation acceptance. Participants’ education level and income were both negatively associated with their acceptance of health misinformation. (shrink)

Food safety and food quality are two closely related aspects of the food management system. The difference between the two is that one keeps consumers safe while the other keeps consumers satisfied. This study examined the differences in how consumers value food safety and food quality with a focus on the influence of loss aversion on one’s psychological level and of income effect on one’s socio-demographic level. Our findings indicate that loss aversion and income effect significantly influence the way consumers (...) value food safety vs. quality labels when considering potential health risks and food price. High risk-averse and low-income consumers with strong loss aversion and a weak income effect show a higher demand for food safety labels as a way to ensure easy access to safety indications. Low risk-averse and high-income consumers with weak loss aversion and a strong income effect show a higher demand for food quality labels because they hope to gain more health benefits from high-quality food at good prices. This study provides insights that will assist public authorities and food industry in balancing food safety control and food quality improvement in order to meet the heterogeneous market demand changing alongside the transition of China’s food consumption and production.

The article explores a gradual refinement of the notion of reflection in Husserlian phenomenology. In his early period, Husserl takes phenomenological reflection to attain adequate evidence, since its object is self-given in an absolute and complete manner. However, this conception of reflection does not remain unchanged. Husserl later realizes that immanent perception or phenomenological reflection also involves a certain horizonality and naivety that has to do with its temporal nature and must be queried in a further critical, apodictic reflection. Focusing (...) more on the notion of apodicticity than adequacy, Husserl subsequently ascribes a new methodological role to reflection: instead of a mere epistemic warrant that guarantees for us the ultimate truth of our experiential life once and for all, phenomenological reflection ensures the strictness of phenomenology insofar as it entails an ethical-existential dimension as the norm of a life-form where the subject pursues full self-understanding and self-justification.

This study empirically examines whether firms’ environmental capital expenditures impact institutional investors’ investment decisions in the Chinese market. We particularly examine the impact of ownership type on the relationship of environmental capital expenditures and the behavior of different types of institutional investors by classifying institutional investors into two categories, short-term and long-term investors. In addition, this study further investigates whether environmental capital expenditures related to ownership type increase firm value. We find that long-term institutional investors tend to invest in state-owned (...) firms making environmental capital expenditures. Results also indicate that, with governmental backing and encouragement, the market value of SOEs making more environmental capital expenditures is likely to increase. However, no similar results are found for non-SOEs. (shrink)

Job satisfaction, resilience, and teacher well-being, as the three major psychological variables emotioncy- based education, have received special attention among English as a foreign language researchers. To pursue the line of this inquiry, this particular study aimed to investigate the relationship between Chinese EFL teachers’ job satisfaction, resilience, and their well-being. To conduct the study, 343 Chinese EFL teachers with different academic qualifications, various academic degrees, and different majors voluntarily participated in this study. The results of the study showed that (...) job satisfaction and resilience could jointly predict 56.4 of the variance in psychological well-being. Both variables were the significant predictors of well-being, while job satisfaction was a better predictor, uniquely explaining 29.6 of well-being’s variance. Based on the findings, some pedagogical implication for administrators, educational institutions, and EFL teachers were discussed in the article. (shrink)

The present article aims to illuminate a notion of finite freedom in both Heidegger and Levinas. Levinas criticizes the Heideggerian ontology for holding an egoistic, unconstrained notion of freedom. The article first responds to such a criticism by showing that the Heideggerian notion of freedom as self-binding involves normativity. It then argues that both Heidegger and Levinas propose a notion of finite freedom as the unity of autonomy and heteronomy. Finally, the article also sheds light on what different approaches to (...) the source of normativity separate the two philosophers’ understandings of freedom. (shrink)

Recent studies have revealed an astonishing diversity of sex chromosomes in many vertebrate lineages, prompting questions about the mechanisms of sex chromosome turnover. While there is considerable population genetic theory about the evolutionary forces promoting sex chromosome replacement, this theory has not yet been integrated with our understanding of the molecular and developmental genetics of sex determination. Here, we review recent data to examine four questions about how the structure of gene networks influences the evolution of sex determination. We argue (...) that patterns of epistasis, arising from the structure of genetic networks, may play an important role in regulating the rates and patterns of sex chromosome replacement. (shrink)

ABSTRACTThe guiding question of this comparative study is the relation between transcendental theory and common-sense realism: how to understand their compatibility, but also possible tensions between the two. This question concerns, in a broader sense, the relation between philosophy and natural life, or more precisely, what philosophy possibly can and cannot do for natural life. In the following discussion, I first introduce the idealism-realism controversy in Husserl’s transcendental phenomenology. I then move on to McDowell’s theory and look into a significant (...) convergence between the two philosophies, namely, their insistence on the “unboundedness” of subjectivity, and I clarify how this shared viewpoint makes their proposals compatible with common-sense realism. In a third section, I elaborate the relation between a transcendental and a natural stance by turning to Husserl’s method of phenomenological reduction. In the end, by attending to the anti-naturalism of Husserl and McDowell, I wish to shed s... (shrink)

ABSTRACTThis paper examines critically the notion of reflection as self-objectification and points out its insufficiency in accounting for the pathological phenomenon of hyperreflexivity. It proposes an understanding of reflection as situated and motivated from within a world and having a normative aspect that concerns the very life of the reflecting person. On this account, the paper argues, on the one hand, that both phenomenological reflection and hyperreflexivity can be viewed as forms of reflection characterized by loss of the world. On (...) the other hand, by construing the phenomenological loss as imaginative vis-à-vis the real loss of hyperreflexivity, the paper emphasizes a difference between the two domains. (shrink)

Prior research suggests that ownership structure is associated to corporate social responsibility (CSR) in developed countries. This article examines whether and how ownership structure affects CSR in emerging markets using Chinese firms' social responsibility ranking. Our empirical evidences show that for non-state-owned firms, corporate ownership dispersion is positively associated to CSR. However, for state-owned firms, whose controlling shareholder is the state, this relation is reversed. We attribute the reversed relationship to political interferences and further test this hypothesis by demonstrating that (...) regional economic development is negatively related to CSR for state-owned firms due to decreased political interference in more developed areas. This study is the first to directly examine the relationship between the dispersion of corporate ownership and CSR in emerging markets, and our results depict that it is important to consider ownership type in assessing CSR in emerging market where state ownership is still prevalent such as China. The results also reveal that firm size, profitability, employee power, leverage, and growth opportunity affect CSR in China. (shrink)

To realize the coordinated and sustainable development of hydropower projects and regional society, comprehensively evaluating hydropower projects’ influence is critical. Usually, hydropower project development has an impact on environmental geology and social and regional cultural development. Based on comprehensive consideration of complicated geological conditions, fragile ecological environment, resettlement of reservoir area, and other factors of future hydropower development in each country, we have constructed a comprehensive evaluation index system of hydropower projects, including 4 first-level indicators of social economy, environment, safety, (...) and fairness, which contain 26 second-level indicators. To solve the problem that existing models cannot evaluate dynamic nonlinear optimization, a projection pursuit model is constructed by using rough set reduction theory to simplify the index. Then, an accelerated genetic algorithm based on real number coding is used to solve the model and empirical study is carried out with the Y hydropower station as a sample. The evaluation results show that the evaluation index system and assessment model constructed in our paper effectively reduce the subjectivity of index weight. Applying our model to the social impact assessment of related international hydropower projects can not only comprehensively analyze the social impact of hydropower projects but also identify important social influencing factors and effectively analyze the social impact level of each dimension. Furthermore, SIA assessment can be conducive to project decision-making, avoiding social risks and social stability. (shrink)

This study aims to optimize the enterprise criminal law-based copyright protection. This exploration discusses the role of the entrepreneurial spirit in criminal law-based copyright protection. To study the relationship between ES and criminal law-based copyright protection, the concepts of ES, criminal law-based copyright protection, and enterprise innovation are given. Next, by collecting literature, hypotheses are put forward. They include the relationship between ES and enterprise innovation, ES and the criminal law-based copyright protection, and the intermediary role of ES in the (...) criminal law-based copyright protection and economic growth. Then, relevant models are established. Finally, the hypotheses are tested through experiments and empirical analysis, and the model is regressed to test the experimental data’s robustness and the scale’s reliability and validity. The empirical analysis shows that: the significance of ES under the 1% index is greater than 0. It indicates that the higher the managers’ ES is, the greater the enterprise innovation is. The significance of criminal law-based copyright protection on ES under the 1% index is greater than 0 and the regression coefficient is 0.59. This shows that criminal law-based copyright protection has a significant positive impact on ES. Under the l% index, the significance of ES on economic growth is greater than 0 and the regression coefficient is 0.63. It shows that ES mediates the relationship between criminal law-based copyright protection and economic growth. Therefore, strengthening criminal law-based copyright protection improves the ES and leads to faster enterprise and regional economic development. Therefore, the state should pay attention to criminal law-based copyright protection to encourage innovation to promote enterprise development. This exploration studies the relationship among ES, economic growth, enterprise innovation, and criminal law-based copyright protection. The finding provides a theoretical reference for criminal law-based copyright protection. (shrink)

The evolution of a variety of important chromophore‐dependent biological processes, including microbial light sensing and mammalian color vision, relies on protein modifications that alter the spectral characteristics of a bound chromophore. Three different color opsins share the same chromophore, but have three distinct absorptions that together cover the entire visible spectrum, giving rise to trichromatic vision. The influence of opsins on the absorbance of the chromophore has been studied through methods such as model compounds, opsin mutagenesis, and computational modeling. The (...) recent development of rhodopsin mimic that uses small soluble proteins to recapitulate the binding and wavelength tuning of the native opsins provides a new platform for studying protein‐regulated spectral tuning. The ability to achieve far‐red shifted absorption in the rhodopsin mimic system was attributed to a combination of the lack of a counteranion proximal to the iminium, and a uniformly neutral electrostatic environment surrounding the chromophore.

Cancer care has transitioned from clinical-based to home-based care to support longterm care in a more familiar and comfortable environment. This care transition has put family caregivers (FCGs) in a strategic position as care providers. Cancer care at home involves psychological and emotional treatment at some point, making FCGs deal with the stress of cancer patients frequently. Due to their limited care competencies, they need supportive care from healthcare professionals in cancer stress management. This study aims to examine how types (...) of demanded healthcare information affect the FCG’s role in reducing the stress of female cancer patients. The mindsponge theory was used in conceptual development and interpretation. Bayesian Mindsponge Framework (BMF) analytics were used for statistical analysis on a dataset of 48 spouses (husbands) and 12 other family members in five congested communities of Surabaya, Indonesia. Results showed that among the six types of healthcare information, FCGs with higher demand for cancer-specific information were more likely to need support in reducing the stress of female cancer patients. Meanwhile, FCGs with a higher demand for information about support services were less likely to need support to reduce cancer patients’ stress. Other types of healthcare information have ambiguous effects on the need for support in reducing cancer-induced stress. This study reveals that the demanded cancer-specific information, e.g., cancer prognosis or likely outcome, must be prioritized to assist FCG’s role in managing cancer stress. (shrink)

Adaptation and stress are two main concepts useful for better understanding the phases of illness and health-related human behavior. The two faces of adaptation, adaptation as a process and adaptation as a product, have raised the question of how long the adaptation process will take in cancer trajectories.

This study examines how types of demanded healthcare information affect the FCG’s (...) role in catalyzing the adaptation of female cancer patients. The mindsponge theory was used in conceptual development and results interpretation. Bayesian Mindsponge Framework (BMF) analytics was used for statistical analysis on a dataset of 48 spouses (husbands) and 12 other family members in five congested communities of Surabaya, Indonesia. Results showed that among the six types of demanded healthcare information, FCGs with a higher tendency to demand cancer-specific information are more likely to need support in catalyzing the adaptation of female cancer patients. Meanwhile, FCGs with a higher demand for information on alternative therapies are less likely to need support in catalyzing cancer adaptation. Other types of healthcare information have ambiguous effects on the need for support in cancer adaptation assistance. This study reveals that the demanded cancer-specific information, e.g., cancer’s prognosis or likely outcome, must be prioritized to assist FCG’s role in catalyzing adaptation among female cancer patients. Cancer prognosis and outcomes reflect the future of cancer care results. (shrink)

Entering the challenging and promising knowledge era, it is clear that enterprises should leverage knowledge management activities in improving innovation performance to maintain competitive advantages. This study sheds light on the improvement path of innovation ambidexterity from the perspectives of knowledge redundancy and typical leadership style. It is noted that we determined the research theme through quantitative analysis and conducted qualitative analysis through 209 questionnaire data collected from respondents in different regions and industries in China. The empirical results indicated that (...) knowledge redundancy significantly improves exploratory and exploitative innovation, and transactional leadership negatively moderates the above relationships. This study is of managerial implications to encourage employees to fully master and apply the existing knowledge to strengthen their innovation abilities in value creation. We also contribute to the theories pertaining to knowledge management, innovation, and ambidexterity by providing a deeper understanding of the influencing mechanism of knowledge redundancy in innovation ambidexterity while elaborating on the indirect effects of transactional leadership.

It could be said that chinese aesthetics merges together three cornerstones of the western tradition. It might be intended as the study of beauty in the Platonic sense, because of the vaste debate on the topic rooted back in chinese’s ancient times; it could match the sense of aesthetics as intended by Baumgarten, because of the long tradition of chinese perceptual studies, and it may also be compared to the Hegelian philosophy of art, given the abundance of chinese artistic manufacts (...) and theories. Chinese aesthetics is distinctive and very different from the western one. While the latter tries to grasp the inner beauty of things by breaking them and accounts for beauty as an object, chinese aesthetics considers beauty as a subject, rather aiming at feeling the beauty of things for what they are. Compared to the occidental tradition, which is rooted in sensation but deviates from sensation to pursue a rational goal, chinese aesthetics originates from the sensation and adheres to it all the time. Therefore, the chinese stance makes for a unique and genuine approach to the discipline. (shrink)

The paper presents the prevailing understanding of pre-reflective and reflective experience as a “data-description model”. According to this model, pre-reflective experience is the original datum, the meaning of which is fully determined in the very beginning, whereas reflection is a secondary layer that purports to recover faithfully the meaning of the pre-reflective. The paper spells out the difficulty of this model by looking into the scepticism on reflection. Despite its contribution to explicating the basic level of human consciousness, the data-description (...) model merely attends to the epistemological function of reflection and its orientation towards the past. The aim of the paper is thus to propose an alternative model inspired by the phenomenological-hermeneutical tradition, especially the paradigm of “text” Gadamer and Ricoeur emphasize. By understanding pre-reflective experience as a text, we are able to make explicit the essential role reflection plays for human life and its inherent existential dimension. (shrink)

Fear of cancer is mostly related to cancer recurrence, metastasis, additional cancer, and diagnostic tests. Its legacy as a lethal disease has raised fear of approaching death.

Clinical practice is a part of the integral learning method in nursing education. The use of information and communication technologies (ICT) in clinical learning is highly encouraged among nursing students to support evidence-based nursing and student-centered learning. Through the information-processing lens of the mindsponge theory, this study views performance expectancy (or perceived usefulness) and effort expectancy (or perceived ease of use) as results of subjective benefit and cost judgments determining the students’ ICT using intention for supporting clinical learning, respectively. Therefore, (...) the study examines whether effort expectancy moderates the relationship between performance expectancy and the intention to use ICT among Moroccan nursing students. The Bayesian Mindsponge Framework (BMF) analytics was employed on a dataset of 702 Moroccan nursing students. We found that nursing students’ performance expectancy is positively associated with the intention to adopt ICT and social media, while effort expectancy positively moderates this relationship. Moreover, the model with effort expectancy as the moderator was discovered to have a significantly larger weight than the model with effort expectancy as the direct predictor, validating our information-processing reasoning. This study provides a new perspective on the interplay between the benefit and cost perceptions of ICT use to support clinical learning methods in nursing education. Moreover, given the limited education resources, especially in developing countries like Morocco, we recommend nursing education and training prioritize communicating the benefits of ICTs and social media over ease of use. Doing so would help improve the effectiveness and efficiency of nursing education and training while lowering costs. (shrink)

To better reflect the precise clustering results of the data samples with different shapes and densities for affinity propagation clustering algorithm, an improved integrated clustering learning strategy based on three-stage affinity propagation algorithm with density peak optimization theory was proposed in this paper. DPKT-AP combined the ideology of integrated clustering with the AP algorithm, by introducing the density peak theory and k-means algorithm to carry on the three-stage clustering process. In the first stage, the clustering center point was selected by (...) density peak clustering. Because the clustering center was surrounded by the nearest neighbor point with lower local density and had a relatively large distance from other points with higher density, it could help the k-means algorithm in the second stage avoiding the local optimal situation. In the second stage, the k-means algorithm was used to cluster the data samples to form several relatively small spherical subgroups, and each of subgroups had a local density maximum point, which is called the center point of the subgroup. In the third stage, DPKT-AP used the AP algorithm to merge and cluster the spherical subgroups. Experiments on UCI data sets and synthetic data sets showed that DPKT-AP improved the clustering performance and accuracy for the algorithm. (shrink)
