Estimating the value of a statistical life in China: A contingent valuation study in six representative cities

The value of a statistical life(VSL)is a crucial tool for monetizing health impacts.To explore the VSL in China,this study examines people’s willingness to pay(WTP)to reduce death risk from air pollution in six representative cities in China based on face-to-face contingent valuation interviews(n=3936)from March 7,2019 to September 30,2019.The results reveal that the WTP varied from CNY 455 to 763 in 2019(USD 66-111),corresponding to a VSL range of CNY 3.79-6.36 million(USD 549395-921940).The VSL in China in 2019 is estimated to be CNY 4.76 million(USD 689659).The statistics indicate that monthly expenditure levels,environmental concerns,risk attitudes,and assumed market acceptance,which have seldom been dis‐cussed in previous studies,significantly impact WTP and VSL.These findings will serve as a reference for ana‐lyzing mortality risk reduction benefits in future research and for policymaking.

Comparative Study on Chinese and Western Life Values in the Context of Epidemic

Life values are people’s understanding and view on life.After the COVID-19 outbreak,China quickly adopted policies such as lockdown to control the epidemic,while the west could not adopt.One of the important reasons is that Chinese and western life values are different.Through the comparative analysis on Chinese and western life values,it is found that Chinese traditional life values emphasize collective consciousness,while the west pays attention to individual value.Chinese traditional life values avoid death,while the west faces death directly.China emphasizes the present world,while the west pays attention to introspection.There are also similarities between Chinese and western life values.They both emphasize the realization of life values,desire to surpass life,and regard physical life as a natural process.The main reasons for their differences are different economic bases,different cultural influences,and different religious ideas.Therefore,the comparative analysis of Chinese and western life values has theoretical and practical value.

On Willa Cather's Sense of Values and Philosophy of Life——After Reading The Sculptors' Funeral

What is success? How is success measured? Willa Cather provides us two sets of values.To some people, success is measured in terms of money. To some success means choosing one’s own life and realizing one’s own values. In the novel The Sculptor’s Funeral Cather portrays an artist, who breaks the bondage of the old environment, and becomes a successful sculptor. However, he is regarded as a failure by his local people because the values by which they judge success are not the same.

Self-concept and Marketing Strategies

This contribution of this paper is devoted to the research results in the field of self-expression and self-image of the individual in the world of information processing and cognition. Marketing strategies help make decisions that will help us to bring the subject to market activities. The current trend is a knowledge-based society, skills, abilities, information, storage, and transmission. Our marketing strategy focuses on four key issues： production, respectively service, price, distribution channels, and advertising. It is important to know how to develop an individual＇s current self-image. Implementation strategies are then engaged in transforming decisions into concrete action, meaning, and the decision has to be taken with regard to flexibility and acceptance. The sample consists of 4,420 respondents, men and women in three age groups： 0-15 years, 16-40 years, and 41-60 years. All responded to one question, ＂Where is your center？＂ Respondents had to show on their body. The question was chosen very sensitive, not to predict the answer. Terms soul, psyche, personality would be very manipulative, and therefore were excluded. In line with expectations, the majority of respondents have shown to their head, chest, and abdomen, but were also unconventional answers, in accordance with the preferred self-image and values of the individual. Lessons from research outputs were analyzed by the following processes： general description, item-total correlation, exploratory factor analysis of individual areas, and correlation analysis of individual items. It was found that medium correlations between area of body abdomen and age to 15 years were significant. Mean item-total correlation for areas of body were： Head was 0.35 and chest 0.43, and abdomen 0.22. In the descriptive statistics it was found that most respondents preferred the chest, followed by the head and abdomen. As for the distribution of respondents into three age groups, we found differences between men and women. Next, it was analyzed the relationship between the areas of the body and gender. Statistically significant differences were found on the chest, where women scored more than men, and it was also found significant differences in the abdominal area, where men scored more than women.

Public's Trade-off between a New Risk-based Airport Screening and Asserted Terror Risk Impact:A Stated Choice Survey from Norway

This paper presents a survey-based economic evaluation of security measures protecting against the risk of aviation terrorism. A sample of Norwegians were asked to state their choices between different air travel al-ternatives, i.e. travel time, trip costs, fatalities in terrorist acts on air transport and type of passenger screen-ing. Screening was specified as either the current uniform screening or a new risk-based screening in which passengers are divided into three groups: high-risk, medium-risk and low-risk. Respondents were informed that risk-based screening implied they would have to identify themselves using a biometric identity card and that those not qualifying as low-risk passengers would be checked with body scanners. Our results indicate that the sampled passengers were very concerned about privacy. Maintaining existing uniform screening was preferred to a new risk-based screening system, even though risk-based screening was presented as poten-tially preventing future terrorist fatalities.

The monetary value of human lives lost due to neglected tropical diseases in Africa

Background:Neglected tropical diseases(NTDs)are an important cause of death and disability in Africa.This study estimates the monetary value of human lives lost due to NTDs in the continent in 2015.Methods:The lost output or human capital approach was used to evaluate the years of life lost due to premature deaths from NTDs among 10 high/upper-middle-income(Group 1),17 middle-income(Group 2)and 27 low-income(Group 3)countries in Africa.The future losses were discounted to their present values at a 3%discount rate.The model was re-analysed using 5%and 10%discount rates to assess the impact on the estimated total value of human lives lost.Results:The estimated value of 67860 human lives lost in 2015 due to NTDs was Int$5112472607.Out of that,14.6%was borne by Group 1,57.7%by Group 2 and 27.7%by Group 3 countries.The mean value of human life lost per NTD death was Int$231278,Int$109771 and Int$37489 for Group 1,Group 2 and Group 3 countries,respectively.The estimated value of human lives lost in 2015 due to NTDs was equivalent to 0.1%of the cumulative gross domestic product of the 53 continental African countries.Conclusions:Even though NTDs are not a major cause of death,they impact negatively on the productivity of those affected throughout their life-course.Thus,the case for investing in NTDs control should also be influenced by the value of NTD morbidity,availability of effective donated medicines,human rights arguments,and need to achieve the NTD-related target 3.3 of the United Nations Sustainable Development Goal 3(on health)by 2030.

Economic burden of premature deaths attributable to different heatwaves in China: A multi-site study, 2014-2019

It has been well documented that heatwaves are linked to elevated mortality and morbidity.However,the selection of optimal heatwave definitions for subsequent risk assessment has been inconsistent and there is no full picture of the effects of heatwaves with different intensities on economic losses due to mortality,which can provide important insights for public health considerations.Hence,we used a two-stage time series analysis,combined with values of statistical life(VsL)based on the value of a statistical life year to assess the economic burden of deaths associated with heatwaves of different intensities and durations and to identify the vulnerable populations and regions.We further conducted stratified analyses by age,sex,and region.We found 2.9%(95%CI:0.0%,6.5%)-20.0%(95%CI:2.9%,34.2%)of VsL were attributable to heatwaves,corresponding to attributable economic losses(AELs)of 2.20(95%CI:0.32,3.77)-4.77(95%CI:1.53,7.63)billion CNY.The economic burden of death was most sensitive to heatwave H99P_2D(99th percentile,at last 2 consecutive days),while H97.5P_2D(97.5th percentile,at last 2 consecutive days)caused the highest attributable economic losses.Females and elderly people aged≥65 years were more sensitive.The AELs in the temperate zone and northern regions were larger than those in subtropical zone and southern regions during relatively low-intensity heatwaves,respectively.By contrast,the AELs in subtropical zone and southern regions were relatively higher than those in temperate zone and northern regions during relatively high-intensity heatwaves,respectively.The AELs were larger in urban areas than in rural areas.Tailored intervention strategies,primarily focusing on vulnerable populations and regions,should be formulated to reduce the economic loss due to heatwaves in the context of climate change.

Integrating OWA and Data Mining for Analyzing Customers Churn in E-Commerce

Customers are of great importance to E-commerce in intense competition.It is known that twenty percent customers produce eighty percent profiles.Thus,how to find these customers is very critical.Customer lifetime value(CLV) is presented to evaluate customers in terms of recency,frequency and monetary(RFM) variables.A novel model is proposed to analyze customers purchase data and RFM variables based on ordered weighting averaging(OWA) and K-Means cluster algorithm.OWA is employed to determine the weights of RFM variables in evaluating customer lifetime value or loyalty.K-Means algorithm is used to cluster customers according to RFM values.Churn customers could be found out by comparing RFM values of every cluster group with average RFM.Questionnaire is conducted to investigate which reasons cause customers dissatisfaction.Rank these reasons to help E-commerce improve services.The experimental results have demonstrated that the model is effective and reasonable.

The modern context and ancient resources of Chinese literature

To enter into and utilize the resources of ancient literature is a necessity for literary modernity. In the twentieth century, modern Chinese literature generally adopted four paradigms in pursuit of this objective： the socio-political paradigm that viewed traditional literature in terms of ＂quintessence-dross＂ under the guidance of the Marxist doctrine of the critical inheritance of cultural heritage; the ＂spiritual awakening＂ paradigm that, being inspired by Western schools of thought such as hermeneutics, viewed traditional literature as ＂the source of new literature＂; the scientific-aesthetic paradigm that viewed traditional literature as combining scientific interpretation and modern aesthetics and focused on interpretation, transformation, innovation and creation from within; and the folk paradigm that viewed literary tradition as a narrative of daily life demonstrating the way in which ancient and modern literature were connected in a cultural whole. What is important in the complementary and competitive development of these coexisting paradigms is highlighting ＂problem consciousness＂ in ＂interaction＂ and ＂original creation＂ and the reconstruction of the value of real human life through entering into and reactivating the resources of ancient literature.
