This paper is preoccupied with the delineation of the dialectic of poverty and wealth in Festus Iyayi's Violence. The unbridled struggle between the bourgeois and the proletariat in the novel constitutes the onus of the dialectical materialism which underlies an axiomatic focus of societal superstructure. An application of Kenneth Boulding's theory of protest to the Nigerian social milieu, poignantly reveals that there is a potent foregrounding of the class stratification between the rich and the poor. The paper will further examine how this dichotomy between the highly placed and the down trodden in the novel has graphically accentuated the poverty index in contemporary Nigeria. 展开更多

There is a scarcity of data on TB knowledge from Rajasthan state of India. Objective: The objective of this study was to estimate the prevalence of knowledge about TB and services of TB control programme and to determine its correlates among rural population of Jaipur, Rajasthan. Methods: Cross-sectional community based study was carried out at Model Rural Health Research Unit, Jaipur, a unit of Department of Health Research, Ministry of Health & Family Welfare, Government of India. Results: Study reports the result from 1993 adult participants from 10 villages of 2 sub-districts of district Jaipur. About 88.9% of studied participants knew that TB is an infectious disease and it spreads from TB patient to healthy person in close contact. Only 22.3% of participants knew “DOTS is the treatment for TB”. While, only 58.9% knew “sputum is used for diagnosis of TB” at health centers. Scheduled castes, scheduled tribes and backward classes social groups knew less than the mainstream “General” social group. The observed difference was statistically significant (p 0.05). Logistic regression analysis estimated the relative contribution to knowledge status. Conclusion: The knowledge of study participants on transmission of tuberculosis was similar to knowledge of population in country wide study. They poorly knew sputum is used for diagnosing tuberculosis disease;socio-demographic inequity exists in this knowledge too. People from older age groups, underprivileged social groups and minority need extra educational activities. 展开更多

Karachi, the largest city in Pakistan, having high population growth and a complex health care environment, has highest density of unimmunized (zero dose) and under-immunized children. The main reasons of low immunization coverage in Karachi were lack of governance and accountability in a duplicative and fragmented health management structure, weak and inequitable immunization services, and lack of demand and trust among people for immunization services. The Expanded Programme on Immunization (EPI), Ministry of Health (MOH) in Sindh Province spearheaded a structured and collaborative process to develop strategies for addressing inequity in immunization services towards achieving Universal Immunization Coverage (UIC) in Karachi. The process included a situation analysis with gathering quantitative and qualitative information on the root causes of zero-dose and inequity of the immunization services. The strategies and interventions were developed with multi-layer input and feedback of the stakeholders and partners, and focusing primarily to address gaps in three program areas: governance, leadership and accountability;immunization service delivery;and building demand and trust among the people. The interventions were further prioritized for high-risk areas;identified based on maximum number zero-dose children, presence of large slum areas, measles outbreak and on-going circulation of wild poliovirus. Finally, costing for the Roadmap activities was done through consultation with partners and aligning domestic and external (donor) resources. In this paper, we have highlighted the unique process the Sindh Government undertook in collaboration with the stakeholders and partners to develop strategies and interventions for addressing inequity in urban immunization services in Karachi towards achieving Universal Immunization Coverage (UIC). Similar processes can be adapted, as a potential model, for developing strategies to achieve universal health coverage in the cities of Pakistan and in other countries. 展开更多

This paper analyzes the distribution of rural in the eastern, mid and western China and in five income tax and fee burden and income of the rural households groups from the lowest income group to the highest group from 1986 to 1999. After the analyses, the paper thinks that the distribution of tax and fee between the rural households is inequitable whatsoever it is in the different income groups or in the different regions. The higher the income of the rural household is, the lighter the rural tax and fee burden is. The poorer the rural household is, the heavier the tax and fee burden of the rural household is. The more developed the economy of the region is, the less the rural tax and fee burden of rural household is. In the region that the agriculture is the leading industry, the rural tax and fee burden of the rural household is heavier than that in the region that the agriculture is not dominant. All mentioned above show the regressive characters of the agricultural taxation in rural China. At present the distribution of rural tax and fee burden between the rural household is inequitable. 展开更多

Monkeypox(mpox)has been a public health emergency of international concern that emerged in mid-2022 and has spread to 110 countries.The clinical findings of the disease vary according to the seriousness of the cases.Although its case fatality risk has not been high,a significant percentage of patients require hospitalization.In this context,local initiatives were taken to extend the limited supply of vaccines against the disease;however,such measures have not been sufficient to contain the spread of cases and ensure an equitable distribution of health resources.As a result,endemic regions of low-income countries continue to have insufficient access to mpox vaccination.Despite this and considering the global scope of the disease,there is still little discussion in the literature about the difficulties in achieving adequate vaccination coverage rates for the target population of interest.In this article,we briefly discussed general aspects of the disease,including its surveillance,the current global context of challenges for mpox vaccination,and issues on global allocation of health resources as well as proposed related recommendations. 展开更多

This paper presents some important facts about educational opportunities and students' access worldwide. Specific facts and scenarios are exhibited and provided to compare education opportunities in rich and poor areas in developed and developing countries. Particularly, this paper surveys and compares forces on educational happening in Nigeria and United States. It argues that despite the much acclaimed democratization of access to education, glaring inequalities can be identified in the way educators and how our students are treated. In regards to quantities and quality of educational resources, education is not equally accessed by all students in our today's world. This paper, therefore, recommends that human beings should be given equal access and opportunities to education at all levels; and should be treated with respect and dignity in spite of color, religion, or race wherever they find themselves. This becomes an imperative if mankind is to achieve success in the task of propelling students and Educators to greater achievements. As well, this paper recommends that cultural, institutional, and political powers should be deployed to bring about a more equitable world order. 展开更多

PM_(2.5)pollution variations in different microenvironments would result in PM_(2.5)exposure inequity between rural and urban residents.In this study,the real-time PM_(2.5)exposure of urban and rural residents in China was examined based on portable PM_(2.5)sensors together with activity patterns derived from questionnaire surveys,with a focus on students and senior citizens who are sensitive to air pollution.The results showed that PM_(2.5)exposure varied significantly among different resident groups,with higher PM_(2.5)exposure of rural residents than those of urban residents.PM_(2.5)exposure peaks mostly occurred during(Accompanied)cooking activities owing to strong emissions.Sleeping and resting were the main activities that affected PM_(2.5)exposures of different resident groups,accounting for 60.7%-94.5%of total daily exposures.Furthermore,the long duration of sleeping makes it the predominant activity contributing to PM 25 exposure inequity.It is necessary to obtain point-to-point respiratory volume(respiratory rate)data when measuring real-time PM_(2.5)exposure data and incorporate respiratory volume(respiratory rate)into the analysis of PM_(2.5)exposure.For the first time,this study quantified the PM_(2.5)exposure inequality based on a novel method and can provide useful information for further studies on the exposure inequity. 展开更多

This paper explores how the Chinese government's reluctance/inability to invest in health has influenced the performance of its health system in the context of urban China. It focuses on two related issues. To what extent is the financing of the health care system progressive? To what extent is the utilization of health care services equitable? Section I explains why the Chinese government has become less willing and able to bear the burden of health care during the era of economic reform and inspects the impacts of these changes on the structure of overall health expenditure. The following two sections empirically examine the extent to which the shift toward out-of-pocket spending has made health care less accessible and less affordable for the poor and vulnerable. Section IV explores how inequity in health care and health services has put groups of people who are already socially disadvantaged at more disadvantaged positions. The study finds that the market-oriented health reform in urban China has exacerbated the cost problem that it intended to solve, reduced access to health services for the most vulnerable, and increased the instances of illness-induced poverty. 展开更多

We examine Africa's vaccine manufacturing potential,spurred by the coronavirus disease 2019(COVID-19)pan-demic,while critically analyzing vaccine price inequities and procurement strategies during the pandemic,with anticipation of future outbreaks.Although Africa consumes approximately 25%of the global vaccine supply,over 99%of these vaccines are produced outside the continent,primarily due to insufficient local investment.Vaccine procurement strategies have relied heavily on pooled procurement mechanisms and tiered-pricing mod-els,predominantly controlled by external organizations.Significant disparities in vaccine pricing have resulted in vaccine price inequities,with evidence suggesting price discrimination,where different prices are charged for the same vaccine across countries and regions.While vaccine prices are only one component of vaccination cam-paign costs,the inequitable pricing of vaccines poses serious challenges to fair access,especially in low-income countries.Given the inevitability of future pandemics and other outbreaks,the central question remains:Does Africa possess the capacity to strengthen its vaccine production infrastructure and reduce dependency on ex-ternal suppliers?Our review reveals that,with robust political commitment,enhanced investment in Research and Development,and leveraging the heterogeneous nature of the regional bloc,Africa has made strides toward establishing vaccine manufacturing hubs with the potential for substantial capacity expansion.Furthermore,we argue for a regional campaign based on the principles of the fair priority model as an ethical framework for vaccine procurement,which prioritizes need and ensures equitable distribution,thereby complementing existing pooled procurement arrangements in times of future pandemics.This paper concludes with two key recommen-dations based on lessons learned from the COvID-19 crisis and future preparedness.First,Africa must push for a transparent and equitable tiered-pricing structure to ensure affordability for all Second,intentional and sustained investment in R&D is critical to addressing systemic inequities in vaccine supply,not only for cOVID-19 but for future outbreaks and routine immunization programs. 展开更多

Chronic hepatitis B (CHB) disproportionately affects minority groups in the US, particularly Asian Americans, with numerous factors contributing to this disparity. Of the 2.4 million people living with chronic HBV in the US, 60% are Asian American. Many are unaware of their status and lack access to proper clinical care, with less than ten percent receiving necessary antiviral treatment. Barriers to screening and care include lack of disease awareness, language and cultural barriers, and financial constraints. Additionally, healthcare providers and systems in the US often overlook the importance of CHB, leading to inadequate care. In response, the Center for Viral Hepatitis (CVH) has implemented a community-based outreach program over the past sixteen years, employing a multifaceted approach involving all sectors of society and various organizations to combat health disparities in CHB. This grassroots campaign has proven highly effective, leveraging CVH’s leadership in spearheading numerous collaborative activities with community members, healthcare professionals, and policymakers. We have summarized the key points of CVH's efforts and their significance in combating CHB-related health disparities. The CHB Screening and Awareness Campaign, tailored to the Asian American community, serves as a successful model for increasing CHB screening, linkage-to-care, and addressing socio-cultural barriers and health literacy. Insights from these outreach programs have guided the development of culturally relevant resources and education initiatives. These findings suggest that such community-driven approaches are essential for addressing health disparities. The strategies and outcomes of CVH’s efforts can inform future health initiatives for other minority communities in the US and globally. 展开更多

The medical device and pharmaceutical industries include a range of drugs,machines,instruments,and apparatuses used to prevent,diagnose,treat disease and illness,or aid in rehabilitation for patients,and are expected to grow substantially in the coming years.However,they are often targets of criminal organizations who manufacture and profit from fraudulent products,infiltrating the market with counterfeit medical supply chains.In this paper,we discuss and analyze the extent and nature of this problem and make suggestions for mitigation and prevention of this worldwide challenge.Ultimately,we argue that a holistic approach is essential to addressing this problem,including the creation and dissemination of reliable and good quality data,developing healthcare systems to be more robust,establishing/enhancing intra‐and international cooperation around this issue,and employing effective technological solutions,such as digital tracing. 展开更多

Equal access to social infrastructures is a fundamental prerequisite for sustainable development,but has long been a great challenge worldwide.Previous studies have primarily focused on the accessibility to social infras-tructures in urban areas across various scales,with less attention to rural areas,where inequality can be more severe.Particularly,few have investigated the disparities of accessibility to social infrastructures between urban and rural areas.Here,using the Changsha-Zhuzhou-Xiangtan urban agglomeration,China,as an example,we investigated the inequality of accessibility in both urban and rural areas,and further compared the urban-rural difference.Accessibility was measured by travel time of residents to infrastructures.We selected four types of social infrastructures including supermarkets,bus stops,primary schools,and health care,which were funda-mentally important to both urban and rural residents.We found large disparities in accessibility between urban and rural areas,ranging from 20 min to 2 h.Rural residents had to spend one to two more hours to bus stops than urban residents,and 20 min more to the other three types of infrastructures.Furthermore,accessibility to multiple infrastructures showed greater urban-rural differences.Rural residents in more than half of the towns had no access to any infrastructure within 15 min,while more than 60%of the urban residents could access to all infrastructures within 15 min.Our results revealed quantitative accessibility gap between urban and rural areas and underscored the necessity of social infrastructures planning to address such disparities. 展开更多

Regional inequality significantly influences sustainable development and human well-being.In China,there exists pronounced regional disparities in economic and digital advancements;however,scant research delves into the interplay between them.By analyzing the economic development and digitalization gaps at regional and city levels in China,extending the original Cobb-Douglas production function,this study aims to evaluate the impact of digitalization on China's regional inequality using seemingly unrelated regression.The results indicate a greater emphasis on digital inequality compared to economic disparity,with variable coefficients of 0.59 for GDP per capita and 0.92 for the digitalization index over the past four years.However,GDP per capita demonstrates higher spatial concentration than digitalization.Notably,both disparities have shown a gradual reduction in recent years.The southeastern region of the Hu Huanyong Line exhibits superior levels and rates of economic and digital advancement in contrast to the northwestern region.While digitalization propels economic growth,it yields a nuanced impact on achieving balanced regional development,encompassing both positive and negative facets.Our study highlights that the marginal utility of advancing digitalization is more pronounced in less developed regions,but only if the government invests in the digital infrastructure and education in these areas.This study's methodology can be utilized for subsequent research,and our findings hold the potential to the government's regional investment and policy-making. 展开更多

We recently read the opinion piece titled“Why people should run after positive affective experiences instead of health benefits”,which was carried out by Maltagliati et al.^(1)and published in the Journal of Sport and Health Science.The article started an important discussion about a physical activity(PA)promotion approach that encourages the use of affective experience to PA activity.Although we agree with the authors’point of view and believe that its message can generate an important insight for PA promotion,the authors presented a scenario where behavior change seems to be exclusively dependent on the individual.Recognizing the existence of other barriers to an active lifestyle(e.g.,social inequalities)could enhance the authors’suggested approach because many people live in conditions that reduce their opportunities to engage in affective experiences related to PA;furthermore,affective experiences can vary depending on individual context. 展开更多

This paper studies a strongly convergent inertial forward-backward-forward algorithm for the variational inequality problem in Hilbert spaces.In our convergence analysis,we do not assume the on-line rule of the inertial parameters and the iterates,which have been assumed by several authors whenever a strongly convergent algorithm with an inertial extrapolation step is proposed for a variational inequality problem.Consequently,our proof arguments are different from what is obtainable in the relevant literature.Finally,we give numerical tests to confirm the theoretical analysis and show that our proposed algorithm is superior to related ones in the literature. 展开更多

Built-up land has increased rapidly in recent decades,thus aggravating the competition for land between multiple uses.The increase in urban land can be decomposed into changes in population and changes in built-up land per person.Yet,it is unclear how this decomposition differs by country and how this decomposition changes over time.Moreover,we don’t know whether these changes affect the inequality in built-up land per capita.Here,we analyze the global distribution of built-up land per capita in the year 2020,as well as the changes therein between 1985 and 2020.We find that built-up land per capita in 2020 differs by an order of magnitude between countries,ranging from 15 m^(2) per person in Ethiopia to 734 m^(2) per person in Australia.Moreover,we find a wide range of different change trajectories,including both increases and decreases in built-up land per capita and in total population.As the total area of urban land increased in all countries,decreases in urban land consumption reflect a situation where the population increases faster than the total amount of urban land.We also find a large inequality in urban land consumption across countries,as indicated by a Gini index of 0.47 in 1985,decreasing only slightly to 0.45 in 2020.These findings suggest the need for a regionally differentiated approach to reduce urban land take,focusing first on mitigating further increases in those countries that already have a high urban land consumption. 展开更多
