Logit and Tobit models are employed to conduct empirical analysis and it is found that terrace abandonment increases sequentially among the new, middle, and old generations, confirming that intergenerational differences significantly influence whether farmers abandon terraces and the terrace abandonment scale. Village characteristics and government subsidies significantly influence farmers' terrace abandonment. An increase in the number of migrant workers in the village increases terrace abandonment among new and middle generation farmers, whereas an increase in the distance from the village to the county significantly increases terrace abandonment among old generation farmers. An increase in the village's total population significantly reduces terrace abandonment among new generation farmers. An increase in government subsidies significantly reduces terrace abandonment among middle and old generation farmers. The impact of intergenerational differences on terrace abandonment is more pronounced in low-altitude areas. To reduce terrace abandonment, it is necessary to promote terrace transfer, develop characteristic agriculture, improve terrace farming subsidies, and propose targeted strategies for the different generations of farmers.展开更多

The impact of a parent or caregiver’s posttraumatic stress on non-traumatized children is significant and may lead to adverse development and mental health outcomes. Research Objectives: The objective of this review is to explore both the consequences of parental trauma transmission on descendants’ psychological adjustment and well-being, and the mechanisms through which trauma has been transmitted among im/migrant populations. Methods: Criteria outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guided this systemic review. The questions guiding this review are: (a) What are the consequences of parental trauma transmission on the psychological adjustment and well-being of im/migrant offspring? And (b) What are the psychosocial mechanisms of trauma and resilience transmission among im/migrant populations? Each potential study was assessed based on relevance to the review question(s). Results: Parental trauma can lead to adverse mental health outcomes among descendants including increased internalizing and externalizing problems, the adoption of coping behaviors and worldviews, and worsening school performance. Mechanisms that influence trauma transmission include parental trauma symptom severity, the parent-child dyad, social learning, and family stressors. Pathways of resilience exist across socioecological levels to include individual resilience such as coping skills and meaning making, family resilience, structural protective factors, and social and cultural protective factors. Conclusions: Despite the prevalence of traumatic events throughout the migration process, im/migrant families display strong levels of resilience. Mental health services and providers should incorporate a strength-based approach in designing interventions that are culturally responsive and take into accounts the broader ecological contexts in which im/migrant families live.展开更多

In this paper, through the analysis of the future generations-oriented management mechanisms for intergenerational conflict, the idea of mechanisms and institution building for the coordination and management of intergenerational conflict is put forward. Furthermore, the future generations-oriented virtual negotiation support system (NSS) for intergenerational conflict is developed, built on the analysis of the process simulation of intergenerational wealth transfer, intergenerational equilibrium allocation of resources, and strategies for the mitigation and avoidance of intergenerational conflict, through the application of advanced IT technology. The virtual NSS for intergenerational conflict is helpful to the practical application of the sustainable development theory; on the other hand, it can be applied directly to the intergenerational equilibrium allocation of resources, national economic accounting, formulation of sustainable development strategies and other urgent national economic and social development issues. Finally, the sustainable development theory can be enriched and extended. Therefore, the development of the future generations-oriented virtual NSS for intergenerational conflict has certain theoretical and practical effects on the theory of sustainable development.展开更多

Previous studies showed that early environmental exposure of an embryo may influence postnatal development. To detect whether ICSI operations affect the reproductive health of a male or his offspring, we established assisted reproductive technologies (ART) conceived mouse models, and analyzed gene expression profiles in the testes of both ICSI and naturally conceived (NC) newborn F1 mice using micro-array analysis. Among the differentially expressed genes, we focused on the expression of eight male reproduction-related genes. Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) was used to analyze the expression of these genes in the testes of both adult and old F1 generation mice and adult F2 generation mice. Our results showed that down-regulated and somatic cell-expressed genes in newborn mice retained their differential expression patterns in adult and old F1 generation individuals, implying the persistence and fetal origin of the alteration in the expression of these genes. The intergenerational transmission of differential gene expression was observed, but most changes tended to be reduced in adult F2 generations. Controlled ovarian hyperstimulation (COH) and in vitro fertilization (IVF) mice models were added to explore the precise factors contributing to the differences in ICSI offspring. The data demonstrated that superovulation, in vitro culture, and mechanical stimulation involved in ICSI had a cumulative effect on the differential expression of these male reproductive genes.展开更多

Today＇s society is characterized by its increasing aspiration and demand for activities of social promotion and personal development, that is, activities that tend to reinforce the social fabric in its human and community values, in the elimination of loneliness, or increasing the quality of life, through the full enjoyment of civic rights, common cultural property, or participation in the opportunities offered by public and community life The older population has transformed their habits, integrating new values generated by social changes. In turn, it leads to possible changes in social intervention. These include training, leisure, tourism, social skills development, the use of the Internet as a tool for knowledge and communication, and social participation. These new social behaviors can be an opportunity to build a more cohesive and supportive society, without generational breaches And this line, the attention to diversity and its even processes seeks to expand its reach, generating intergenerational spaces展开更多

This paper has employed the method of two sample instrumental variables to effectively integrate CHIP data and CFPS data and correct the temporal income bias, life-cycle bias and coresidence bias, which are common problems in existing studies, and investigated the tendencies of intergenerational transmission of income gap for China's urban and rural households between 2002 and 2012. Results of empirical study indicate that the intergenerational transmission of income gap for China's urban and rural households has been on the decline yet the level of intergenerational transmission is greater for urban residents than for rural residents. This level of intergenerational transmission of income gap in China is at a medium international level lower than that of countries like the United States, Brazil and Japan and higher than that of Sweden and Chinese Taiwan. Further analysis of the intergenerational mobility of various income groups suggests the following: the intergenerational solidification of the bottom and top income groups of urban residents has significantly improved, which is the source for the reduction of intergenerational transmission of income gap. Rural residents of bottom income group are vulnerable to falling into the trap of intergenerational transmission of low income. In order to mitigate the intergenerational transmission of income gap, efforts must be made to improve educational allowance policy and increase the opportunities for children from poor and underprivileged families to receive education and to eliminate the divide of labor markets to create equal job opportunities for each and every worker.展开更多

Through a comparative study of the liberal theory of intergenerational equity, this paper shows that at least in the contemporary social context of China, filial piety still acts as an important moral foundation and value basis for the intergenerational distribution of old-age support resources. The emphasis on an intergenerational contract based on filial piety not only presents a theoretical perspective transcending liberalism for addressing the issue of intergenerational equity in the context of contemporary China, but also provides significant and irreplaceable institutional resources. Starting from the Confucian family-centered theory of social justice and through the reconstitution of traditional ethical resources, this paper explores a family-centered, multi-level old-age security system to cope with the issue of intergenerational equity against the backdrop of population aging.展开更多

文摘The progress of modern medicine would be impossible without the use of general anesthetics(GAs).Despite advancements in refining anesthesia approaches,the effects of GAs are not fully reversible upon GA withdrawal.Neurocognitive deficiencies attributed to GA exposure may persist in neonates or endure for weeks to years in the elderly.Human studies on the mechanisms of the long-term adverse effects of GAs are needed to improve the safety of general anesthesia but they are hampered not only by ethical limitations specific to human research,but also by a lack of specific biological markers that can be used in human studies to safely and objectively study such effects.The latter can primarily be attributed to an insufficient understanding of the full range of the biological effects induced by GAs and the molecular mechanisms mediating such effects even in rodents,which are far more extensively studied than any other species.Our most recent experimental findings in rodents suggest that GAs may adversely affect many more people than is currently anticipated.Specifically,we have shown that anesthesia with the commonly used GA sevoflurane induces in exposed animals not only neuroendocrine abnormalities(somatic effects),but also epigenetic reprogramming of germ cells(germ cell effects).The latter may pass the neurobehavioral effects of parental sevoflurane exposure to the offspring,who may be affected even at levels of anesthesia that are not harmful to the exposed parents.The large number of patients who require general anesthesia,the even larger number of their future unexposed offspring whose health may be affected,and a growing number of neurodevelopmental disorders of unknown etiology underscore the translational importance of investigating the intergenerational effects of GAs.In this mini review,we discuss emerging experimental findings on neuroendocrine,epigenetic,and intergenerational effects of GAs.

文摘Intracytoplasmic sperm injection (ICSI) is commonly used to solve male infertility problems. Previous studies showed that early environmental exposure of an embryo may influence postnatal development. To detect whether ICSI operations affect the reproductive health of a male or his offspring, we established assisted reproductive technologies (ART) conceived mouse models, and analyzed gene expression profiles in the testes of both ICSI and naturally conceived (NC) newborn F1 mice using micro-array analysis. Among the differentially expressed genes, we focused on the expression of eight male reproduction-related genes. Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) was used to analyze the expression of these genes in the testes of both adult and old F1 generation mice and adult F2 generation mice. Our results showed that down-regulated and somatic cell-expressed genes in newborn mice retained their differential expression patterns in adult and old F1 generation individuals, implying the persistence and fetal origin of the alteration in the expression of these genes. The intergenerational transmission of differential gene expression was observed, but most changes tended to be reduced in adult F2 generations. Controlled ovarian hyperstimulation (COH) and in vitro fertilization (IVF) mice models were added to explore the precise factors contributing to the differences in ICSI offspring. The data demonstrated that superovulation, in vitro culture, and mechanical stimulation involved in ICSI had a cumulative effect on the differential expression of these male reproductive genes.

文摘Families'large pollution and energy consumption cannot be underestimated.In order to realize and internalize environmental awareness as a social consensus,it is imperative for every member of a household to be involved in transforming everyday behavior.Intergenerational interactions are of paramount importance.Accordingly,the focus of this study was on parent-adolescent interactions,their reciprocal impact on environmental behaviors,and the factors that have an influence on these processes.Questionnaires were employed to collect information of 684 families in 10 districts of Jinan,the capital of Shandong Province.Subsequently,interviews were conducted with 15 of these families to comprehend the tangible reasons underlying intergenerational interactions in environmental behaviors.First,a paired sample T-test was employed to compare the frequency of these interactions.The data showed that while the T values were positive in all eight compared groups,there were significant differences in seven of them.These results suggest that the impact of intergenerational interactions on environmental behaviors is not symmetrical:parents'instructions are far more frequent than adolescents'back-feeding of ecological notions.The interviews revealed that this phenomenon was generated primarily by unequal experiences between parents and adolescents because the latter do not participate in housework and family projects.Furthermore,the traditional concept of intergenerational order appears to be permanent.Second,two linear regression models,a Parent-to-Adolescent model and an Adolescent-to-Parent model that encompassed several factors including family structure,intergenerational relationships,living environment,and families'social class were developed.Among these factors,the intergenerational relationship variable played a particularly significant role:the more equal and open-minded dialogs are incorporated into parent-adolescent communication,the more favorable interactions may occur for development of their environmental behaviors.Thus,when an environmental education system with families is constructed,it is imperative to promote a parent's ecological awareness with the help of grass-roots organizations by means of reasonable rewards and punishments to redress their former behaviors so as to let Big Hands Guide Small Hands.It is also crucial to enhance a more equal intergenerational relationship through parents'schooling or other relevant services so as to create a favorable atmosphere for Small Hands Guide Big Hands.
文摘The research presents the progressive increase of lifelong education and its influence on the paradigm of socio-educational inclusion. Today＇s society is characterized by its increasing aspiration and demand for activities of social promotion and personal development, that is, activities that tend to reinforce the social fabric in its human and community values, in the elimination of loneliness, or increasing the quality of life, through the full enjoyment of civic rights, common cultural property, or participation in the opportunities offered by public and community life The older population has transformed their habits, integrating new values generated by social changes. In turn, it leads to possible changes in social intervention. These include training, leisure, tourism, social skills development, the use of the Internet as a tool for knowledge and communication, and social participation. These new social behaviors can be an opportunity to build a more cohesive and supportive society, without generational breaches And this line, the attention to diversity and its even processes seeks to expand its reach, generating intergenerational spaces
文摘Based on ten rounds of CHNS data from 1989 to 2015,this paper employed dual measurement indicators of the intergenerational elasticity(IGE)of earnings and the income rank association(IRA)coefficient to measure intergenerational income mobility in China.Our findings suggest that China’s intergenerational income mobility was relatively stable from 1991-2004 and started to increase after 2004.Our study based on income grouping found that the intergenerational income immobility decreased after 2004 for all income groups;however,the high-income and low-income groups were far more immobile than other income groups;the middle-income group served as a key driver of the relatively high intergenerational income mobility in China.Furthermore,we investigated China’s intergenerational income transmission mechanism with a human capital analysis framework.We found that fathers’non-education factors played a dominant role in intergenerational income transmission;under the effects of the social institutional environment,the non-education transmission mechanism started to diminish after 2004,significantly contributing to intergenerational income mobility.
基金Project of National Social Sciences Foundation Empirical Study on the Intergenerational Transmission of Income Gap(Grant No.14BJY039)
文摘An accurate understanding of the intergenerational transmission of income gap is the foundation for theoretical research and policy formulation to address this issue. This paper has employed the method of two sample instrumental variables to effectively integrate CHIP data and CFPS data and correct the temporal income bias, life-cycle bias and coresidence bias, which are common problems in existing studies, and investigated the tendencies of intergenerational transmission of income gap for China's urban and rural households between 2002 and 2012. Results of empirical study indicate that the intergenerational transmission of income gap for China's urban and rural households has been on the decline yet the level of intergenerational transmission is greater for urban residents than for rural residents. This level of intergenerational transmission of income gap in China is at a medium international level lower than that of countries like the United States, Brazil and Japan and higher than that of Sweden and Chinese Taiwan. Further analysis of the intergenerational mobility of various income groups suggests the following: the intergenerational solidification of the bottom and top income groups of urban residents has significantly improved, which is the source for the reduction of intergenerational transmission of income gap. Rural residents of bottom income group are vulnerable to falling into the trap of intergenerational transmission of low income. In order to mitigate the intergenerational transmission of income gap, efforts must be made to improve educational allowance policy and increase the opportunities for children from poor and underprivileged families to receive education and to eliminate the divide of labor markets to create equal job opportunities for each and every worker.

文摘As the aging population continues to grow in China the issue of intergenerational equity in the field of old-age security has become increasingly prominent. Through a comparative study of the liberal theory of intergenerational equity, this paper shows that at least in the contemporary social context of China, filial piety still acts as an important moral foundation and value basis for the intergenerational distribution of old-age support resources. The emphasis on an intergenerational contract based on filial piety not only presents a theoretical perspective transcending liberalism for addressing the issue of intergenerational equity in the context of contemporary China, but also provides significant and irreplaceable institutional resources. Starting from the Confucian family-centered theory of social justice and through the reconstitution of traditional ethical resources, this paper explores a family-centered, multi-level old-age security system to cope with the issue of intergenerational equity against the backdrop of population aging.
文摘Research on the changes of Lichuan dialect mostly focuses on microlinguistics such as specific vocabulary,syntactic or semantic research,less on the language use and language attitude in sociolinguistics.Therefore,This study mainly discusses the differences of intergenerational language attitude of Lichuan dialect and the reasons so as to protect traditional dialects in China.11 participants were interviewed.The results reveals the reasons:(1)internal reasons of personal dialect attitudes including cultural confidence,social identity,dialect inheritance;(2)language attitudelanguage contact such as educational background,rural-urban migration,study and work with people from different cities and media development.
文摘China's rapid population aging and remarkable family-level changes have raised concerns about the weakening of its family-based elderly care.The last decade indeed has seen a clear departure from multigenerational living to alternative living arrangements such as living with spouse only and solo living.However,ample evidence suggests that Chinese families have demonstrated considerable resilience amidst profound sociodemographic changes.This review article highlights the importance of government–society cooperation in meeting the social challenges of population aging.A key factor is the persistient filial piety norms,which enable children living far or close,migrant or nonmigrant,to rearrange financial,instrumental,and emotional support to aging parents.Equally important is the step-in of the government to share elderly care responsibilities,provide support through deepening pension and healthcare reforms,and implement the active and healthy aging agenda.How the two factors play out over the next decade and beyond will have profound implications on the living arrangement,intergenerational support,and wellbeing of older adults in China.
文摘For the early generation of both Chinese and Indian immigrants,their deep immersion in their own language and cultural environment has given their life experience an indelible nostalgia.However,the children of their descendants born in the United States have no such cultural heritage and spiritual burden,their thinking on values,languages,education,occupation,clothing,social communications,etc.are more largely Americanized and culturally identified with the mainstream society.In this way,the various intergenerational conflicts reflected in Chinese and Indian American literature implies the importance of negotiation through the use of shared resource between the old and new identities to balance,adapt and integrate in the adopted land.
文摘Intergenerational education is very common among aging population and at the time when birth restrictions are lifted.Studies have shown that intergenerational education proceeds negatively and has issues in which children develop psychological problems when the knowledge of the elderly do not keep up with the younger generations*12*5,the older educational ideas struggle against the modem ones,and so on,that further bring issues in the lack of self-identity and capacity from grandparents.Bad relationships between family members can affect the family,particularly in the communication between elderly caregivers and their grandchildren.It could further influence the parent-child relationship if unpleasant emotions pile up.

文摘Objective:To examine the impact of hypertensive disorders of pregnancy(HDP)on offspring metabolomics.Methods:We searched five databases:PubMed,Ovid Embase,MEDLINE,Web of Science,and China National Knowledge Infrastructure,and included studies that reported metabolomics among human offspring born to HDP-complicated pregnancies.Results:Database search yielded 4054 articles,and after full-text screening,ten observational studies met inclusion criteria.Half of the studies had a sample size of less than 100 and were all observational studies in preeclampsia(PE)and gestational hypertension.Neonates were the most focused group in all included studies.Offspring born to HDP-complicated pregnancies exhibited statistically significant variations in blood metabolomics compared to their counterparts,characterized by amino acids,lipids,carnitine,and others(e.g.,1α,25-(OH)_(2)-D).Most studies reported a significant increase in differential metabolites of offspring born to HDP-complicated pregnancies.Four studies(n=1109)measured lipids-related metabolites,and all consistently showed that offspring born to PE-complicated pregnancies had significantly higher concentrations than non-PE exposed offspring.Conclusion:The existing evidence suggests an intergenerational effect of HDP on offspring metabolomics.Long-term follow-up studies are needed to advance the health effects of related adverse health outcomes and inform the prevention of offspring’s health.
