Study on Influencing Factors of Mental Health of Mobile Young White-Collar Workers in China

Mobile young white-collar workers not only have the characteristics of mobile young people,but also have the characteristics of general white-collar workers.Under the influence of both,their mental health may be suffering from“double disadvantage”.So,based on an ecological model of the stress process,this paper tries to use the data of the questionnaire on the mental health of mobile young white-collar workers in Zhejiang Province to explore the influence of some factors in the middle workplace and residence place on the mental health of micro individuals.The results show that:(1)The working environment with high control and low freedom and the workplace discrimination against the mobile status will have a negative impact on the mental health of mobile young white-collar workers;(2)Financial anxiety in daily life will lead to a decline in the mental health level of mobile young white-collar workers;(3)Good organizational support and neighborhood social relations can significantly relieve life pressure,so as to effectively improve the mental health of mobile young white-collar workers.It can be seen that we also need to pay more attention to the mental health of mobile young white-collar workers in order to improve their situation.

A Study on the Influence of Social Media Use on Psychological Anxiety among Young Women

To explore the relationship between social influence,social comparison,clarity of self-concept,and psychological anxiety among young women during their usage of social networking sites,our study selected 338 young women aged 14-34 from the social site platforms of Little Red Book and Weibo for questionnaire surveys.The Passive Social Network Utilization Scale,Social Comparison Scale(SCS),Social Influence Questionnaire,Self-Concept Clarity Scale(SCCS),and Generalized Anxiety Disorder Scale(GAD-7)were employed to measure the subjects.Our results show that the frequency of passive social media use is positively related to the level of psychological anxiety.Social comparison,social influence,and unclear self-concepts under social media use are negatively predictive of psychological anxiety.The chain mediation effects indicate that social comparison and social influence under social media use negatively predict the clarity of self-concept,thus having a negative impact on the psychological health of young women.Therefore,young women should strengthen their self-concepts,control their frequency of social media usage,avoid addiction,and pay special attention to their frequency of passive use,in order to protect their psychological health.Our study provides some practical implications and insights regarding the relationship between young women’s social media use and psychological health.

Farmers’ Knowledge and Perceptions of the Effects of Climate Variability and Pollution on Crop Production and Their Varying Adaptation Strategies in The Gambia

Crop and livestock production is critical to food security in The Gambia. Over the years, the country has experienced a reduced yield due to perceived climate change events with limited studies on how climate change and pollution affect crop production. This study assesses farmers’ knowledge and perceptions of the effects of climate variability and pollution on crop production and their varying adaptation strategies in The Gambia. Both quantitative and qualitative methods were used in this study. The sample size for quantitative data collection was calculated as 432 while the qualitative data involves both the focus group discussions and key informant interviews. The focus group discussions comprised two districts in each of the six agricultural regions and two farming communities engaged in crop production were chosen from each district. Furthermore, eight key informant interviews from relevant institutions were conducted. The study shows that The Gambia is highly vulnerable to extreme climatic events. Although most farmers opined that agricultural land contamination emanates from farm runoff and indiscriminate waste dumping, they had little knowledge of heavy metal pollution and bioremediation. The results showed that farmers experienced constraints such as inadequate access to credit, water, and irrigation facilities, insufficient access to efficient inputs, salt intrusion, etc. which threatened food security. The study concludes that crop farmers acknowledged the existence and impacts of climate change, and therefore recommend the availability and affordability of climate change resilient crops and promote variability awareness campaigns to address climate change impacts in The Gambia.

Impact of Social Media Challenges on Pediatric Single-Use Detergent Sacs and Diphenhydramine Ingestions Reported to United States Poison Control Centers

Background: Social media platforms are popular among children and often feature challenges that become viral. Notably, the Tide Pod® and Benadryl® challenges encouraged viewers to ingest these substances for their visual appeal and hallucinogenic effects, respectively. This study aimed to assess the clinical impact and outcomes of single-use detergent sacs (SUDS) and diphenhydramine challenges on pediatric ingestions reported to United States (U.S.) Poison Control Centers (PCCs). Methods: We conducted a retrospective review of pediatric exposures reported to U.S. PCCs using data from the National Poison Data System (NPDS). The study included intentional single-substance ingestions of both brand-name and generic forms of SUDS and diphenhydramine among children ≤ 19 years. We compared the number of calls, clinical effects, disposition, and management strategies for SUDS (pre: 01/01/17 to 12/31/17 vs. post: 01/01/18 to 12/31/18) and diphenhydramine (pre: 08/01/19 to 07/31/20 vs. post: 08/01/20 to 07/31/21) ingestions 12 months before and after the introduction of the respective social media challenges. Differences in proportions were compared using the Chi-square test. Results: During the study period, 469 ingestions of SUDS and 5,702 ingestions of diphenhydramine were reported. Post-challenge periods saw an increase in both SUDS (pre: 82 vs. post: 387;372% increase) and diphenhydramine ingestions (pre: 2,672 vs. post: 3,030;13% increase). While there were no significant changes in moderate or major clinical outcomes, hospitalizations increased post-challenge for both SUDS [pre: 4 (4.9%) vs. post: 33 (8.5%);p = 0.25] and diphenhydramine [pre: n = 904 (33.8%) vs. post: 1,190 (39.3%);p Conclusion: Pediatric ingestions reported to U.S. PCCs and hospitalizations increased coinciding with the introduction of Tide Pod® and Benadryl® challenges. While causality cannot be definitively established, it is essential for pediatricians and parents to be aware of these challenges and educate vulnerable children about the harmful effects of participation in such challenges.

Violence study of healthcare workers and systems in the Caribbean:ViSHWaS-Caribbean study

BACKGROUND Violence against healthcare workers(HCWs)in the Caribbean continues to prevail yet remains underreported.Our aim is to determine the cause,traits,and consequences of violence on HCWs in the Caribbean.AIM To determine the cause,traits,and consequences of violence on HCWs in the Caribbean.METHODS This research adopted an online cross-sectional survey approach,spanning over eight weeks(between June 6th and August 9th,2022).The survey was generated using Research Electronic Data Capture forms and followed a snowballing strategy to contact individuals using emails,social media,text messages,etc.Logistic regression analysis was performed to evaluate the variables that influence violence,including gender,age,years of experience,institution type,and night shift frequency.RESULTS The survey was completed by 225 HCWs.Females comprised 61%.Over 51%of respondents belonged to the 21 to 35 age group.Dominica(n=61),Haiti(n=50),and Grenada(n=31)had the most responses.Most HCWs(49%)worked for government academic institutions,followed by community hospitals(23%).Medical students(32%),followed by attending physicians(22%),and others(16%)comprised the most common cadre of respondents.About 39%of the participants reported experiencing violence themselves,and 18%reported violence against colleague(s).Verbal violence(48%),emotional abuse(24%),and physical misconduct(14%)were the most common types of violence.Nearly 63%of respondents identified patients or their relatives as the most frequent aggressors.Univariate logistic regression analyses demonstrated that female gender(OR=2.08;95%CI:1.16-3.76,P=0.014)and higher frequency of night shifts(OR=2.22;95%CI:1.08-4.58,P=0.030)were associated with significantly higher odds of experiencing violence.More than 50%of HCWs felt less motivated and had decreased job satisfaction post-violent conduct.CONCLUSION A large proportion of HCWS in the Caribbean are exposed to violence,yet the phenomenon remains underreported.As a result,HCWs’job satisfaction has diminished.

Significance of music therapy in treating depression and anxiety disorders among people with cancer

Globally,cancer cases and mortality have recently escalated and have attracted global concern.The clinical diagnosis and manifestation of cancer can result in significant mental health issues like depression and anxiety disorders.The tendency of people with cancer to suffer from psychological disorders such as anxiety and depression is usually high.A significant number of deaths related to cancer may likely not be from the killer disease but from psychological disorders associated with the illness.The utilization of music as a remedial approach to healing mental disorders cannot be overstated.Thus,identifying the impacts of music therapy in dealing with depression and anxiety disorders among people with cancer is relevant,as the majority of methods used in treating cancer have some side effects which may trigger psychological disorders in cancer patients.Ultimately,this study explored the significance of music therapy in treating depression and anxiety disorders among people with cancer.To achieve the aim of this study,the authors employed a narrative literature review to investigate the significance of music therapy in addressing depression and anxiety disorders among people with cancer.The type of literature review employed in this study is to provide an understanding of the selected research papers.The review found that music therapy significantly reduces depression and anxiety disorders among breast cancer,lung cancer,prostate cancer,and colorectal cancer patients.It is needful for healthcare providers to incorporate music therapy interventions while treating people with cancer.This will help reduce cancer deaths resulting from psychological disorders rather than the killer disease,cancer.However,the standardized procedures and evaluation criteria for applying music-based intervention strategies in oncology medicine still need to be further established and improved.

Addressing the needs and rights of sex workers for HIV healthcare services in the Philippines

The right to health for all people means that healthcare services and programs are available,accessible,and acceptable for everyone in need.However,certain groups in the society may be marginalized from their needed healthcare services.In this regard,this paper discusses the challenges in providing HIV-related services to sex workers,a group that remains marginalized in Philippine society.

Accessibility and utilization of healthcare services among diabetic patients:Is diabetes a poor man’s ailment?

Diabetes is a non-communicable ailment that has adverse effects on the individual’s overall well-being and productivity in society.The main objective of this study was to examine the empirical literature concerning the association between diabetes and poverty and the accessibility and utilization of medical care services among diabetic patients.The diabetes literature was explored using a literature review approach.This review revealed that diabetes is an ailment that affects all individuals irrespective of socioeconomic status;however,its prevalence is high in low-income countries.Hence,despite the higher prevalence of diabetes in developing countries compared with developed countries,diabetes is not a poor man’s ailment because it affects individuals of all incomes.While the number of diabetic patients that access and utilize diabetes medical care services has increased over the years,some personal and institutional factors still limit patients’access to the use of diabetes care.Also,there is a lacuna in the diabetes literature concerning the extent of utilization of available healthcare services by diabetic patients.

Who Is More Vulnerable?The Age-Period-Cohort Effect of Psychological Distress among Urban Residents in China

How does psychological distress evolve over time?This study utilizes cross-sectional data from the China General Social Survey from 2010 to 2017 to explore the differences in psychological distress among Chinese residents at various ages,periods,and cohorts.The dummy variable method and random effects hierarchical age-period-cohort model were employed to isolate the age,period,and cohort effects that impacted the psychological distress of Chinese urban residents.First,in terms of the age effect,the psychological distress experienced by residents tends to increase initially and then decrease with age.Middle-aged individuals,around 40 years old,often face a particularly severe form of psychological distress known as the“midlife crisis.”Additionally,middle-aged people who have larger families may experience more significant psychological distress due to increased family burdens.Second,in terms of the period effect,the psychological distress experienced by residents has been on the rise due to the continued development of society.Those who are at a disadvantage in market competition and work longer hours may be particularly vulnerable to increased psychological distress.Thirdly,the cohort effect refers to the different social behaviors and attitudes exhibited by individuals of different generations.In terms of this effect,psychological distress initially decreased and then increased among those born between 1945 and 1990.Individuals born in the 1980s and 1990s experienced higher levels of psychological distress,with internet use having a greater negative impact.Additionally,the positive effect of income on their psychological distress was reduced.The psychological distress of Chinese urban residents is affected by a variety of time-related factors,which are closely related to Chinese clan culture,market competition and social changes.The heavy family burden imposed by traditional clan culture,the different working conditions created by market competition,and the emergence of new lifestyles,such as internet use during social changes,have led to diverse psychological distress experiences among residents across different ages,time periods,and cohorts.In the future,longitudinal studies are needed to strengthen the robustness of the conclusions and consider the long-term impact of the COVID-19 pandemic.Mental health support should pay specific attention to the psychological distress of middle-aged individuals,long-time workers,and internet users.

Effect of Online Social Networking on Emotional Status and Its Interaction with Offline Reality during the Early Stage of the COVID-19 Pandemic in China

Background:During the early stages of the COVID-19 pandemic in China,social interactions shifted to online spaces due to lockdowns and social distancing measures.As a result,the impact of online social networking on users’emotional status has become stronger than ever.This study examines the association between online social networking and Internet users’emotional status and how offline reality affects this relationship.Methods:The study utilizes cross-sectional online survey data(n=3004)and Baidu Migration big data from the first 3 months of the pandemic.Two dimensions of online networking are measured:social support and information sources.Results:First,individuals’online social support(β=0.16,p<0.05)and information sources(β=0.08,p<0.01)are both positively associated to their emotional status during the epidemic.Second,these positive associations are moderated by social status and provincial pandemic control interventions.With regards to the moderation effect of social status,the constructive impact of information sources on emotional well-being is more pronounced among individuals from vulnerable groups compared to those who are not.With regard to the moderation effect of provincial interventions,online social support has the potential to alleviate the adverse repercussions of high rates of confirmed COVID-19 cases and strict lockdown measures while simultaneously augmenting the favorable effects of recovery.Conclusion:The various dimensions of social networking exert distinct effects on emotional status through diverse mechanisms,all of which must be taken into account when designing and adapting pandemic-control interventions.

History dynamics of unified empire in China(770 BC to 476 BC)

The laws and regulations in human history can be revealed by computational models.From 221 before Christ(BC)to 1912 Anno Domini(AD),the unification pattern has dominated the main part of Chinese history for 2132 years.Before the emergence of the first unified empire,the Qin Empire in 221 BC,there existed the Eastern Zhou dynasty(770 BC to 221 BC).This long dynasty has two stages,and here we focus on the first stage.This Spring-Autumn stage was from 770 BC(with 148 states)to 476 BC(with 32 states).The whole country(China)is modelled as a multi‐agent system,which contains multiple local states.They behave autonomously under certain action rules(wars and conflicts),which forms the main reason for the annexations and disappearance of most states.Key factors(power,loyalty,bellicosity and alliance)have been considered in our model settings,and simulation outcomes will be monitored and collected.Eventually,an optimal solution is obtained,which well unveils the internal mechanism and statistical features of real big history.Furthermore,counterfactuals are used to explore the non‐linear effects of the key factors,which deepens the authors’understanding of civilisa-tion evolutions in human history.

Assessing the Impacts of Climate Change on Water-Borne Diseases: A Comparative Study on Taltali Upazila of Barguna District

Objectives: To determine the economic challenges brought on by water-borne illnesses as a result of climate change. In addition to identifying potential access to safe drinking water during climate change and potential health hurdles brought on by water-related diseases, it is important to learn how to reduce the spread of water-borne diseases. Methods: A mixed method design was adopted to evaluate this research, and probability sampling, more specifically simple random sampling, was used to select to sample from the target population. The study was conducted in Taltali upazila of the Barguna district, and data was collected from 384 respondents;among them, 5 respondents were selected for the key informant interview. The research project began in June 2022 and was completed in December 2022. Results: 41.4% of respondents said they suffer from dysentery, 22.4% said the expense of treating water-borne diseases has increased as a result of climate change, and 37.8% said they must travel great distances to obtain clean drinking water. Currently, 41.7% of individuals utilize tube-well water, compared to 19.3% five to ten years ago, and 27.4% have been taught that water filtration helps reduce the spread of water-borne diseases. Conclusions: People’s vulnerability to climate change in the study area is a result of factors such as rapid population increase, unequal access to resources, food insecurity, a long distance to collect water, inadequate medical facilities, a lack of poverty, and a weak health system.

Ignored Engagement: A Piloted Theory about Social Aspects of Aging

The society and culture of Bangladesh are quite different from the other countries of the world. It is difficult to receive a theory fully for explaining the condition of our own. However, the purpose of this paper is to review major sociological theories on aging and propose a new one. Data were collected from both primary and secondary sources. Content analysis and survey methods were used in this study. Through the baseline survey of four villages in the Bogra District of Bangladesh, 609 older people have been identified. Among them, 203 older people including 96 males and 107 females have been selected as a sample randomly and interviewed intensively. The contents of aging-related theories have been analyzed. The results of this study show that existing theories of aging are inadequate to explain the social aspects of older adults in Bangladesh;rather Ignored Engagement (A Piloted Theory) may be suitable to do this. This study may give future direction to academicians and policymakers to formulate and amend evidence-based policies and practices for the well-being of our older people.

Expanding Older Adults’ Care Choices Utilizing the Proceeds of Reciprocated Volunteerism: Capitalizing on Ghana’s Digitalization Artillery

Ghana has been a collectivistic society. However, due to social change, this value is fast being replaced by individualistic tendencies with implications for age-oriented care provision and receipt. This paper investigates the participation in the socially productive strategy of using ageing-oriented volunteerism to leverage the receipt of care in later life utilizing a quantitative dataset. The results show that volunteering may be undertaken with old age in sight. This needs to take place under circumstances of good communication skills among others. The accumulated time needs to be recorded in a time bank and redeemed with a time bank card in later life. Two-dimensional leveraging points pertain in this context: first, leveraging volunteerism for short or long-term care in the nearest future;second, technological innovation’s facilitation of the same. Volunteerism in this context has the attribute of low levels of depression, with implications for quality of life. These are discussed in the light of the social care pillar of ageing social policy. The paper argues that adopting volunteerism with reciprocation as the ultimate goal constitutes a kickback model for care receipt in later life. It served as a choice of care in later life which is a shock absorber to inadequate formal support infrastructure and individualistic social tendencies in Ghana. It is reminiscent of resistance to the shrinkage of older persons’ social integration in their social world.

Perspectives on enhancing vaccination coverage and confidence in the Philippines

Vaccination plays a vital role in protecting against communicable infections like measles and their associated complications[1,2].While vaccination doesn't guarantee complete immunity,the authors also highlighted that vaccinated individuals tend to experience milder infections compared to those who are unvaccinated[1].Despite the availability of free vaccines for measles,polio,and pertussis through the national vaccination program[3],the Philippines faced outbreaks of measles and pertussis across its islands in 2024[4].The Bangsamoro Autonomous Region in Muslim Mindanao reported 500 measles cases,while pertussis outbreaks were recorded in various parts of Luzon and Visayas,prompting several cities to declare states of calamity[4,5].Additionally,despite successfully eradicating poliomyelitis in 2000,approximately 70 percent of provinces and cities remained at high risk of polio outbreaks[3,4].

A perspective on utilizing the minority stress model for HIV and mental health care for men who have sex with men

In 2022,the Joint United Nations Programme on HIV/AIDS(UNAIDS)and the World Health Organization(WHO)called upon global,regional,national,and local stakeholders to embrace a holistic approach to person-centered HIV prevention,treatment,and care[1].This approach emphasizes integrating mental health and psychosocial support services into existing frameworks[1].It recognizes the critical role these services play in addressing mental distress and improving the overall well-being and quality of life for people living with HIV[1].In light of men who have sex with men(MSM)remaining a key population affected by HIV[1],it becomes imperative to delve into the shared factors that influence their HIV care and mental health,among which minority stress stands out as a critical consideration.

A Content Analysis Study Describing Information Regarding Female Genital Mutilation Present in US Medical Textbooks

This study examines the depth of information regarding Female Genital Mutilation (FGM)/Female Cutting (FC) present in US medical textbooks. According to Klein et al. (2018) [1], despite substantial attention regarding the effects of FGM, this practice is still ongoing all over the world. Healthcare providers are very important actors who need to understand FGM in order to provide care to girls and women subjected to it, but the small amount of existing work in this area shows a low level of knowledge and training about FGM/FC among U.S. physicians. The Center for Disease Control and Prevention (CDC) first published the estimated number of girls at risk of FGM/FC in the U.S. to be about 168,000 in 1997;that number had increased to 513,000 girls in the US by 2012 (according to Goldberg et al.) In this study, a small sample of medical textbooks were analyzed for the degree to which the textbooks include information regarding FGM/FC. The results of this study show that US medical textbooks do not include information regarding FGM/FC, suggesting that most medical providers don’t have knowledge and training about FGM/FC. The inadequate information on FGM/FC in medical textbooks reflects a culturally biased lack of recognition of the number of girls and women affected in the US. This maintains an ongoing pattern of silence that reinforces gender inequality. Considering the inadequate information covered in US medical textbooks on FGM/FC, and the concordant lack of provider training to provide advice and care to affected girls and women, incorrect and missed diagnoses may lead to harm to victims of FGM/FC. Providers would be better equipped to care for women and girls if their medical training included information regarding FGM/FC.

The Status and Associated Factors of Successful Aging among Older Adults Residing in Longevity Areas in China

Objective This study aims to assess the status of successful aging （SA） in longevity areas in China and explore multiple factors associated with SA among the young-old and oldest-old. Methods A total of 2296 elderly people aged 65 and older were interviewed in the longevity areas sub-sample of the Chinese Longitudinal Healthy Longevity Survey （CLHLS） in 2012. Baseline assessments included a researcher-administered questionnaire, physical examination, and laboratory testing. A logistic regression model was used to identify factors associated with SA. Results The prevalence of SA was 38.81% in the CLHLS in 2012. There were significant differences between ages groups, with SA compromising 56.85% among _〉65 years group and 20.31% among 〉100 years group （X2trend=126.73, P〈O.01）. The prevalence of SA among females was 33.59%, which was significantly lower than that among males （45.58%） （X2gender=33.65, P〈0.05）. In the regression analysis, having anemia ~OR=0.744, 95% CI： 0.609-0.910）, poor lifestyle （OR=0.697, 95% CI： 0.568-0.854）, poor sleep quality （OR=0.558, 95% CI： 0.456-0.682）, and central obesity （OR=0.684, 95% CI： 0.556-0.841） were the main factors associated with SA. The promoting SA rate decreased as age increased, and the group of 65-79 years had higher odds than the other age group. Conclusion Preventing central obesity, improving sleep quality and promoting healthy lifestyle may contribute to achieve SA among the elderly.

Long-Term Fate of Agent Orange and Dioxin TCDD Contaminated Soils and Sediments in Vietnam Hotspots

The soils, tropical climate, and network of canals and rivers of southern Vietnam have created one of the most diverse tropical jungles and intensely cultivated landscapes of Southeast Asia. This paradise has a long history of numerous wars, foreign occupations, and most recently the Second Indochina War (aka the Vietnam War 1965-1972) which defoliated rain forests and ancient wetland mangroves and left behind contaminated soil and sediment hotspots. During this war, the United States (US) military sprayed 80 million liters of Agent Orange contaminated with the dioxin TCDD in a guerrilla war against communist insurgents. Agent Orange was a synthetic plant growth regulator comprised of equal amounts of two herbicides 2,4-dichloro phenoxyacetic acid C8H6Cl2O3 (2,4-D) and 2,4,5-trichlorophenoxyacetic acid C8H5Cl3O3 (2,4,5-T). TCDD, the dioxin, 2,3,7,8-tetrachlorodibenzodioxin (C12H4Cl4O2) was an unintended byproduct of the accelerated combustion process used in the manufacture of herbicides containing 2,4,5-T. Agent Orange has frequently been blamed for soil and sediment contamination and long-term human health problems;however, the true source of harm is the dioxin TCDD. Agent Orange has a short half-life of days and weeks after application to vegetation, and has not been found to persist, after 50 years, in the water or soils of southern Vietnam. However, the half-life of dioxin TCDD depends on where it is deposited and varies from 1 to 3 years on soil surfaces that have been fully exposed to sunlight, to as long as 20 to 50 years or more when buried in tropical subsoils, and more than 100 years in river and sea sediments. Dioxin TCDD was heavily concentrated in the US Air Force bases in Vietnam where the herbicides were stored, loaded on planes and helicopters for aerial spraying, and used extensively around military base perimeter fences as a security measure to prevent surprise attacks. Bien Hoa Air Force base, 40 km northeast of Ho Chi Minh City, continues to be one of the mega-hotspots where after 48 years the dioxin TCDD levels in fish and shrimp are still high and fishing is banned in ponds and lakes adjacent to the airbase. Although expensive, one of the most effective remediation to dioxin TCDD contaminated soils is incineration which is the recommended method of dioxin TCDD disposal.

Soil and Crop Damages as a Result of Levee Breaches on Ohio and Mississippi Rivers

Whenever levees on the Ohio or Mississippi rivers are breached, there are soil damages in the flooded areas that impact agricultural management capacities and crop productivity. Floodwaters coat the entire flooded land surface with sediments which include a variety of pollutants, nutrients and contaminants. The nature of the sediments in floodwaters varies with the topographical and land use characteristics of the watershed. The soil types, hydro-geologic features, volume of flow, time of year, agricultural use of fertilizers, pesticides, and other chemicals as well as upstream point sources such as sewage treatment plants, storm sewer drainage and other urban land uses will affect the extent of the contamination and fine scale remediation needed. Preliminary characterization and measurement of soils and sediment deposit at three locations that experienced recent natural and man induced levee breaches are analyzed to identify patterns of soil and crop damage. These findings provide guidance to the restoration of craters, gullies, land scoured areas and contaminated sediment depositional sites with a goal to improve decision-making, risk analysis and remedial effectiveness. Recommendations include： （1） improve characterization and measurement of eroded soils and distribution of sediment contaminants after levee breaching; （2） assess contamination effects on soil productivity and long term agricultural production in order to understand the impacts of flooding on agricultural soils; （3） evaluate reconstruction investments needed to repair levees based on return of the land to productivity and increased landscape resilience by reducing vulnerability to future flooding and levee breaching stress.
