摘要：
The aim of the study is to determine the trajectories of physical activity and depressive symptoms and their reciprocal relationship among community-dwelling older adults in the COVID-19 pandemic era. The study population consisted of a cohort of 511 participants aged 60 years and over, who were recruited from eight community health centers in Ya'an, China. The Physical Activity Scale for the Elderly and the Patient Health Questionnaire were respectively used to measure physical activity and depressive symptoms at three time points: before the COVID-19 outbreak (T(0)), during the outbreak period (T(1)), and after the subsidence of COVID-19 (T(2)). The results revealed that physical activity and depressive symptoms fluctuated substantially across T(0), T(1), and T(2). In addition, more severe depressive symptoms at T(0) and T(1) were significantly associated with lower levels of physical activity at T(1) and T(2), but the obverse direction of physical activity being associated with subsequent depressive symptoms was not observed in the current study. These findings highlight the importance of supporting old people to remain physically active and combat mental distress early in a pandemic, and prevention and management of depressive symptoms may also be beneficial to promote physical activity.

Differential game;online advertising;spillover effect;bargaining model
摘要：
A differential game model has been utilised in this paper to analyse the dynamic strategic problems of online advertising in a two-echelon supply chain. First, the level of spillover effects has been introduced to examine the impact of different types of online advertising. Second, based on the improved Lanchester model, a dynamic investment decision model for online advertising has been developed. The results of the simulation describe the market share, online advertising investment amount and profit changes over time. Finally, by using the Rubinstein bargaining model, a proposal for a distribution mechanism is developed to achieve the coordination of a two-echelon supply chain system under strategic alliances. We find that: (1) The e-retailer's use of position-fixed online advertising is inversely proportional to the spillover effect. (2) When the two e-retailers are in a symmetrical position, the manufacturer is better off by choosing the e-retailer to form the strategic alliance; when in an asymmetric position, a manufacturer is expected to choose to not give e-retailer subsidies to maximise the supply chain profits. (3) The party with a stronger negotiation ability may bear more losses even though it may gain more profits.

摘要：
This is the first study to assess nurses' attitudes and skills regarding grief counseling for bereaved family members of patients who died from coronavirus disease 2019 (COVID-19) in Wuhan, China. Using a cross-sectional design, 412 nurses selected through convenience sampling completed a demographic characteristics survey, Attitudes of Grief Counseling Scale, (AGCS) and Skills of Grief Counseling Scale (SGCS). Average AGCS score was 32.89 (SD = 9.46), with an overall percentage rate score of 65.6%. Factors influencing attitudes toward grief counseling included other grief counseling skills, educational level, communication skills, and training related to grief counseling (p < 0.05). Average SGCS score was 18.81 (SD = 4.25), with an overall percentage rate score of 58.7%. Factors influencing skills of grief counseling included responsibilities and roles, frequency of contact with the bereaved, and positive view of grief counseling (p < 0.05). Nurses' attitudes and skills regarding grief counseling were low, indicating an urgent need to improve grief counseling.

摘要：
To face the challenges from fierce competition in traditional industry and increasing concern on environment protection, hotels in China are seeking practice of green supply chain (GSC), which helps in both raising operation efficiency and minimising environmental impacts. Rooting from a case study in China's hotel industry, this study intends to firstly build a new conceptual model of hotel GSC by integrating the concept of front-back stage decoupling. Then a mathematical model based on the concept of ant colony labour division is constructed to explain and verify the mechanism of the new GSC model. Moreover simulation is conducted for model testing and further discussion, which finally leads to the conclusions and future research suggestion.

alexithymia;social interaction anxiousness;boredom proneness;problematic mobile phone use;college students
摘要：
Purpose: Previous studies have investigated the relationship between alexithymia and problematic mobile phone use (PMPU). However, yet gaps in identifying the internal mechanisms of this relationship remain. Hence, based on the Interaction of Person-Affect- Cognition-Execution model, the current research examined the mediating roles of college students' social interaction anxiousness (SIA) and boredom proneness (BPS) in the relationship between alexithymia and PMPU. Methods: A total of 1300 college students (M-age = 20.36 years, SD = 0.97) were recruited from two universities in the southeast of China to complete a series of questionnaires, including the Toronto alexithymia scale, SIA scale, BPS scale, and mobile phone addiction index questionnaire. In order to conduct conservative predictions, the demographic variables (ie, gender) were controlled as covariates. Results: The results of multiple mediation analysis showed that (1) alexithymia was positively linked with PMPU, (2) both SIA and BPS mediated the link between alexithymia and PMPU; and (3) a serial indirect pathway emerged (ie, alexithymia -> SIA -> BPS -> PMPU). Conclusion: These findings indicated that alexithymia could influence PMPU in a simple indirect way (parallel mediation) and in a complex indirect way (serial mediation). Besides, these findings provide some insights into the prevention and intervention of PMPU.
摘要：
Background: The global outbreak of the novel coronavirus pneumonia (COVID-19) has seriously affected people's work and lives. Disaster-related traumatic stress events increase the risk of substance abuse. Therefore, the COVID-19 outbreak, as a stress event, inevitably has a negative impact on Chinese adolescents with Internet addiction. Methods: In 2020, 1787 copies of the questionnaire were randomly distributed among adolescents aged 12-16 years in three communities in Shandong Province, China. Among the respondents, 121 Internet addicts voluntarily participated and were divided into the experiment group (60 members) and the control group (61 members). Logotherapy-based mindfulness intervention was carried out on the experiment group. The effects of the intervention were analyzed after eight weeks of intervention. Results: After the intervention, significant decreases occurred in the scores of Internet addiction and its five dimensions in the experiment group (P < 0.05), thereby implying better invention effects in the experiment group than the control group. The experiment group exhibited an increase in the positive coping score and a decrease in the negative coping score (P < 0.05). Significant decreases were found in the anxiety and depression scores in the experiment group (P < 0.05). Conclusion: Logotherapy-based mindfulness intervention can significantly reduce the degree of Internet addiction among adolescents during the COVID-19 period, improve their positive emotions, reduce their negative emotions, and alleviate the degree of anxiety and depression in adolescents.

customer satisfaction index model;elderly satisfaction;nursing services;COVID-19;China
摘要：
Based on the customer satisfaction index model, we constructed an elderly care service satisfaction model that includes 5 latent variables and 16 observed variables. To analyze the degree of satisfaction of elderly individuals in nursing homes, we used structural equation model (SEM) to test the nursing service elderly satisfaction model. With the help of AMOS 22.0 software, we analyzed the degree of model fit and the behavioral relationships between the variables that affect the path. We found that the satisfaction of Chinese urban elderly individuals in nursing homes is at a moderate level, which is lower than the quality expected by elderly individuals. The customer satisfaction index model can be applied to assess satisfaction with nursing services. Furthermore, perceived quality and value have a significant impact on satisfaction.</p>

摘要：
In this paper, an eco-efficiency analysis is conducted using the epsilon-based measure data envelopment analysis (EBM-DEA) model for Russian cities along the Northern Sea Route (NSR). The EBM-DEA model includes five input variables: population, capital, public investment, water supply, and energy supply and four output variables: gross regional product (GRP), greenhouse gas (GHG) emissions, solid waste, and water pollution. The pattern of eco-efficiency of 28 Russian cities along the NSR is empirically analyzed based on the associated real data across the years from 2010 to 2019. The empirical results obtained from the analysis show that St. Petersburg, Provideniya, Nadym, N. Urengoy, and Noyabrsk are eco-efficient throughout the 10 years. The results also indicate that the cities along the central section of the NSR are generally more eco-efficient than those along other sections, and the cities with higher level of GRPs per capita have relatively higher eco-efficiency with a few exceptions. The study provides deeper insights into the causes of disparity in eco-efficiency, and gives further implications on eco-efficiency improvement strategies. The contributions of this study lie in the fact that new variables are taken into account and new modeling techniques are employed for the assessment of the eco-efficiency of the Russian cities.

摘要：
China's tourism industry has made remarkable achievements since reframing and beginning, but the imbalanced expansion of regional tourism has become increasingly severe. This paper involves the analysis of combining index analysis and factor analysis and employs SPSS software to make a quantitative analysis on the differences and the contributory factors of the tourism economy in Yangtze River Delta in China from 2006 to 2016. The results have demonstrated that there exists an imbalance in the development of tourism economy in the Yangtze River Delta, and that there is a significant spatial difference with a yearly trend of decrease. Besides, a major gap lies among the comprehensive development level of tourism economy of the cities in theYangtze River Delta. In this paper, Fuzzy analytic hierarchy process is used for making decision based analysis process for tourism economy. The comprehensive development level of tourism economy in Shanghai, Suzhou and Nanjing is much higher than that in other cities. Tourism resources endowment, tourism reception facilities and the development level of regional economy are important contributory factors of the regional differences of economy based on tourism in river delta of Yangtze, and there exists an extremely obvious positive correlation.

smart city construction;quality of public occupational health;policy effect;difference-in-difference model;Guangdong Province
摘要：
This article takes the Guangdong Province of China as the research object and uses the difference-in-difference model to evaluate the impact of smart city construction on the quality of public occupational health and intercity differences. The obtained results show that smart city construction significantly improves the quality of public occupational health, and it is still valid after a series of robustness tests. The effect of this policy is stronger in cities that belong to the Pearl River Delta region or sub-provincial level cities. This study indicates that the central government should improve the pilot evaluation system and the performance appraisal mechanism of smart cities from the perspective of top-level design during the process of promoting smart city construction, which aims to correctly guide local governments to promote the construction of smart cities. To achieve the full improvement effect of smart city construction on the quality of public occupational health, local governments should implement smart city strategies in a purposeful and planned way according to the actual situation of the development of the jurisdiction.
摘要：
We investigate the frill and price decisions for a competitive e-market with online reviews. To do this, we develop two-period game-theoretical models for the constructed different frill scenarios, respectively. By comparing the equilibrium decisions, we determine the optimal frill and price strategies. We find that: (1) The high-quality retailer will always offer frills to consumers, however, the low-quality retailer offers frills only when its frills have low effectiveness; (2) Offering frills to consumers will increase the two retailers' profits, when there is a small quality difference and low effectiveness of frills; (3) Intuitively, a low-quality retailer would offer more frills to improve its online reputation. However, from our result, retailers might spend more resources promoting superior products in a competitive context; (4) Better online reviews entailed by the offered frills will encourage retailers to raise their respective product prices.

metro maintenance staff;risk perception;safety citizenship behavior;mediating role
摘要：
The accident rate is high in subway maintenance work, and most of the accidents are caused by human factors, especially the lack of sensitivity to risk perception, the lack of rigorous attitude towards safety and the lack of safe citizenship behavior (SCB). Therefore, it is very important to study the risk perception (RP), safety attitude (SA) and SCB of metro maintenance staff in order to reduce the accident rate. In order to reduce human errors and accidents, this study analyzed the influence of metro maintenance staff's RP on their SCB and the mediating role of SA. Based on previous studies, this paper uses the risk perception scale, safety attitude scale and safety citizenship behavior scale as research tools. A survey was administered at the Subway Company, and altogether 268 valid questionnaires were used, and the data were analyzed by SPSS19.0 (IBM, Armonk, NY, USA) and AMOS 24.0 (IBM, Armonk, New York, NY, USA). The result reveals that SA plays a complete mediating role between metro maintenance staff's RP and their SCB; and SA has a positive influence on SCB; RP has a positive influence on SA; and SA positively predicts SCB.

suicidal ideation;resilience;loneliness;depressive symptoms;nursing home residents
摘要：
Suicide in later life is becoming severe under rapid population aging, especially for nursing home residents. Loneliness, an increasingly represented issue among nursing home residents, is found to be a risk factor for depressive symptoms. Both loneliness and depressive symptoms may contribute to the development of suicidal ideation. According to the Protective Factor Model, resilience can act as a moderating role interacting with risk factors to buffer the negative effects on the outcome. The present study aimed to assess the mediating role of depressive symptoms and the moderating effect of resilience on the risk factors of suicidal ideation to attenuate the adverse contribution among nursing home residents. A total of 538 nursing home residents participated in this cross-sectional study, and their suicidal ideation, resilience, loneliness, and depressive symptoms were measured. The mediating effect and moderated mediation model were tested using the Macro Process of SPSS 21.0. Statistics showed that 19.7% of participants had suicidal ideation. The mediating model (H1: B = 0.477, p < 0.001; H2: B = 0.325, p < 0.001; H3: B = 0.308, p < 0.001) and the moderating effect of resilience interacting loneliness (H4: B = −0.133, p < 0.001; H6: B = −0.109, p < 0.001) and depressive symptoms (H5: B = −0.077, p < 0.001) were statistically significant. The findings indicated the protective effect of resilience in alleviating the negative influence of risk factors for suicidal ideation, suggesting that positive psychological interventions for resilience building might be effective in suicide prevention among nursing home residents.

摘要：
The current study investigates the impact of fear related to coronavirus 2019 (COVID-19) disease on situational humor, and also on social networking sites (SNS) usage as a mediator. Furthermore, this study investigates the impact of fear-related COVID-19 disease on situation humor via SNS usage, focusing on the gender perspective of university students. This study also examined the impact of fear related to COVID-19 disease on situational humor in students from various degree programs, such as BS and MS. For this cross-sectional study, data were collected from 24 different Pakistani universities using purposive sampling between December 2020 and May 2021. This study used social media platforms like WhatsApp, Facebook, LinkedIn, and Twitter (and also email) to collect data online. According to the findings of this study, fear related to COVID-19 disease was found to be significantly negatively related to situational humor and SNS usage, whereas SNS usage was positively related to situational humor. The findings also revealed that SNS usage is a key mediator in the relationship between fear related to COVID-19 disease and situational humor. In addition, male university students used more SNS and had a higher situational humor response than female university students, and female university students reported a higher fear related to COVID-19 disease. This study provided useful findings of the impact of fear related to COVID-19 disease on situational humor among students in various academic programs, such as bachelor's program and master's program.
