Background: Nigeria, a nation grappling with rapid population growth, economic intricacies, and complex healthcare challenges, particularly in Lagos State, the economic hub and most populous state, faces the challenge of ensuring quality healthcare access. The overview of the effect of quality improvement initiatives in this paper focuses on private healthcare providers in Lagos State, Nigeria. The study assesses the impact of donor-funded quality improvement projects on these private healthcare facilities. It explores the level of participation, perceived support, and tangible effects of the initiatives on healthcare delivery within private healthcare facilities. It also examines how these initiatives influence patient inflow and facility ratings, and bring about additional benefits and improvements, provides insights into the challenges faced by private healthcare providers in implementing quality improvement projects and elicits recommendations for improving the effectiveness of such initiatives. Methods: Qualitative research design was employed for in-depth exploration, utilizing semi-structured interviews. Private healthcare providers in Lagos involved in the SP4FP Quality Improvement Project were purposively sampled for diversity. Face-to-face interviews elicited insights into participation, perceived support, and project effects. Questions covered participation levels, support perception, changes observed, challenges faced, and recommendations. Thematic analysis identified recurring themes from interview transcripts. Adherence to ethical guidelines ensured participant confidentiality and informed consent. Results: Respondents affirmed active involvement in the SP4FP Quality Improvement Project, echoing literature emphasizing private-sector collaboration with the public sector. While acknowledging positive influences on facility ratings, respondents highlighted challenges within the broader Nigerian healthcare landscape affecting patient numbers. Respondents cited tangible improvements, particularly in staff management and patient care processes, validating the positive influence of quality improvement projects. Financial constraints emerged as a significant challenge, aligning with existing literature emphasizing the pragmatic difficulties faced by private healthcare providers. Conclusions: This study illuminates the complex landscape of private healthcare provision in Lagos State, emphasizing the positive impact of donor-funded quality improvement projects. The findings provide nuanced insights, guiding policymakers, healthcare managers, and practitioners toward collaborative, sustainable improvements. As Nigeria progresses, these lessons will be crucial in shaping healthcare policies prioritizing population well-being. 展开更多

Since the United Nations Sustainable development goals and the 2030 agenda were initiated in 2015,it has provided governments with a comprehensive blueprint to take action and meet the challenges of the world’s most pressing issues today.But the private sector also plays a large role in contributing to the problems highlighted in the SDGs and companies ranging from many different industries have increasingly become more involved in developing new and innovative solutions to solve the issues highlighted in the SDGs.Social and environmental accountability has been one of the areas that the private sector has been focusing its attention on.Companies in the corporate sector across all industries have adopted Environmental,Social,and Governance(ESG)regulations and targets,that aim to ensure ethical responsibility within private companies and promote transparency about their role in promoting social and environmental well-being across the world.This has allowed many companies to align their values and business models to emphasize the importance of the SDGs.Furthermore,innovative technologies are being utilized to ensure that public reports about the company’s practices are fully accountable and transparent to the public community and the overall private sector.For example,some private companies are using Natural Language Processing and Artificial Intelligence to analyze sustainable practices highlighted in the company’s ESG reports and see if they are genuine and free of greenwashing.This shows that technologies are playing a key role in promoting corporate accountability in terms of sustainability and encouraging private companies to adhere to the guidelines highlighted within the SDGs.Furthermore,private companies have adapted their business models to better promote innovations and collaboration with governments,other private companies as well as NGOs.Since the SDGs were designed to be interconnected and not siloed into their own different challenges,many companies who adopt the SDGs as a major sustainability framework will often develop partnerships and connections with other private sector groups so that they could develop new innovative solutions to meet the challenges posed by current global issues.This is especially prevalent in the clean energy sector,which aims to solve SDG 7 and SDG 13 both important in eradicating the issue of climate change.For example,the solar energy private sector has been currently collaborating with a wide range of universities and research institutions in order to develop solar panels that are more energy efficient and affordable for everyday consumers,while still allowing the private companies to generate significant returns in revenue.When private sector Industries adopt the measures highlighted in the SDGs,not only does it allow them to work with other industries to contribute to combating the world’s most pressing issues,but also maintains and improves their sources of revenue and profit.Overall,in order to meet the world’s most pressing challenges and issues,the private sector has increasingly adopted the SDGs in their business models,so that they would be able to better collaborate with others to develop innovative solutions and to bridge commitment to sustainable development throughout different industries. 展开更多

This paper investigates optimal decisions for private banking development in China under two innovative organizational structures—the big retail mode(BRM)and the independent development mode(IDM).Under the BRM,the retail and private banking divisions form a cooperative relationship wherein the former transfers highnet-worth customers to the latter.In addition,retail banking receives a share of private banking revenues.We investigate the optimal revenue-sharing ratio between the two divisions and the optimal effort by private banking to serve transferred customers within the cooperative relationship.The analytical results show that as the private banking division becomes more developed,the optimal revenue-sharing ratio decreases,and the private banking division’s optimal effort to serve transferred customers decreases because it puts more effort into acquiring new customers.Under the IDM,the two divisions form a competitive relationship since they compete to acquire customers independently.We investigate customer acquisition efforts in this interdivisional competition.Optimal customer acquisition efforts by both divisions increase in potential assets and rates of return.This paper contributes to the literature by(1)analyzing financial innovation by private banks from an organizational perspective;(2)providing an economic analysis for private banking development in China. 展开更多

From the perspective of regulatory focus theory,the influencing mechanism of pro-environmental behaviors(PEBs)in the private domain on behaviors in the public domain were analyzed by revealing the mediating ef‐fect of the status quo maintenance and the moderating effect of the prevention focus orientation.The study re‐sults show that PEBs in the private domain significantly promote individuals’PEBs in the public domain.The status quo maintenance partially mediates the relationship between PEBs in the private and public domains.Specifically,individuals with a high-level prevention focus orientation strengthen the relationship between the PEBs in the private domain and the status quo maintenance,and that of the PEBs in the public domain.There‐fore,individuals with a high-level prevention focus will more likely engage in subsequent PEBs in the public domain after their initial PEBs in the private domain due to their increased status quo maintenance degree.Policymakers and practitioners should pay attention to the prevention-repetition effect and use the PEBs in the private domain to promote those in the public domain. 展开更多

At present,the legal remedies in terms of the right to equal employment in China are mainly related to private law,that is,laborers seek direct legal remedies for personality rights liability and infringement liability according to typical private law,supplemented by indirect remedies for labor contract liability under special private law.However,there are many challenges in private law remedies for the right to equal employment,which are manifested in the misunderstanding of the general tort identification of employment discrimination,the loopholes in the regulations on discriminatory employment,the imbalance in the burden of proof,and the limitation and alienation of the functions of civil liability and private law autonomy.The root of those problems lies in the fact that the nature of anti-employment discrimination law is not private law but social law.Equal employment involves both public and private interests,and it should be based on the public interest of society and adhere to the value orientation of prioritizing fairness while taking into account efficiency.Improving the legal relief mechanism for protecting the right to equal employment,with a focus on correcting private law with social law,is the solution to the dilemma.Specific measures include establishing the special tort liability system for equal employment,the legal mechanism against discriminatory labor contracts,the public-private integrated legal responsibility system,and an essentially fair system for the responsibility of adducing evidence. 展开更多

The Qi Yuling case is a crucial juncture in the study of “fundamental rights and private law” in China, yet relevant research is underpinned on two clues. The first is that the increasing interest in the “constitutionalization of private law” worldwide provides knowledge resources and reference materials for scholars in China;the second is the understanding and exploration of the judicial application of the Constitution since the 1980s. Among them, such concepts as “the Constitution has direct legal effect” and “the Constitution needs to be implemented by the people” could have directly affected the Qi Yuling case. Focusing on such topics as the case of Qi Yuling, judicial enforcement of the Constitution, and the compilation of the Civil Code, scholars discussed the ways and scope for inclu ding fundamental rights in private law based on their experience abroad. They also looked into specific issues, covering how fundamental rights affect civil acts and the private law effects fundamental rights like personality rights, equali ty rights, freedom of speech, and protection of personal information. In the context of promoting the full implementation of the Constitution in the new era, “fundamental rights and private law” is still a field with great potential in both practice and theory. 展开更多

We introduce a practical method to perform private membership tests.In this method,clients are able to test whether an item is in a set controlled by the server without revealing their query item to the server.After executing the queries,the content of the server's set remains secret.One use case for a private membership test is to check whether a file contains any malware by checking its signature against a database of malware samples in a privacy-preserving way.We apply the Bloom filter and the Cuckoo filter in the membership test procedure.In order to achieve privacy properties,we present a novel protocol based on some homomorphic encryption schemes.In our protocol,we rearrange the data in the set into N-dimensional hypercubes.We have implemented our method in a realistic scenario where a client of an anti-malware company wants to privately check whether a hash value of a given file is in the malware database of the company.The evaluation shows that our method is feasible for real-world applications.We also have tested the performance of our protocol for databases of different sizes and data structures with different dimensions:2-dimensional,3-dimensional,and 4-dimensional hypercubes.We present formulas to estimate the cost of computation and communication in our protocol. 展开更多

ART is therefore a key pillar in HIV prevention. Appropriate support is however essential for optimum treatment outcome, patient safety and HIV prevention benefit. The scale-up of ART continues to strain the already overstretched human resources in public facilities, impacts on the quality of care, and contributes to loss to follow-up. Task shifting is therefore a strategy to augment the limited human resources. Methodology: In partnership with the Livingstone General Hospital (LGH) and four private pharmacists, the COH III Project through Howard University is promoting quality HIV care by engaging the pharmacists in adherence counselling and treatment monitoring. The LGH ART pharmacist allocates consenting stable ART clients to pharmacies based on willingness to be referred and patient preference. Patients are given schedule of visits to pharmacies where the pharmacists provide medication/adherence counselling and monitor side effects. Patients with medication/treatment issues are referred back to the LGH ART clinic for follow-up. Results: Between October 2012 and August 2013, 280 patients were enrolled and followed up by the four pharmacists. 69% of patients visited the pharmacy at least once, 25% at least twice and 13% at least thrice. The 33 client referrals by pharmacists to LGH were related to adverse drug reactions, suspected treatment failure, pregnancy, and treatment monitoring. The intervention has reduced workload for the ART pharmacist;improved communication of treatment challenges and identification of patients with medication related problems, and reduced travel distances and waiting times. This has resulted in improved adherence and better patient outcomes. Conclusion: Private pharmacists present an opportunity to improve quality of HIV interventions in poor human resource capacity settings. The necessary legal and regulatory framework needs to however be developed to guide the process. 展开更多

A specific application of task-based learning in teaching vocabulary to young learners and a complete task cycle using role play to present vocabulary in China's private language school would be described in the study. The participants aged between 7 and 9 are thought to be starters according to their language competence in Common European Framework of Reference for language. The rationale for stages in the task cycle will be fully explored with reference to Piaget and Vygotsky's theory in teaching young learners. The advantages of the adoption of TBL with young learners will be illustrated and some possible problems in implementing TBL in China, a representative country of Confucian-heritage culture would also be discussed in the paper. The study indicates that young learners in China are quite welcome this new approach in their English classes, but the targeted learners' age and background information need to be taken into consideration when actually implement this approach. 展开更多

This paper investigates the differentially private problem of the average consensus for a class of discrete-time multi-agent network systems(MANSs). Based on the MANSs,a new distributed differentially private consensus algorithm(DPCA) is developed. To avoid continuous communication between neighboring agents, a kind of intermittent communication strategy depending on an event-triggered function is established in our DPCA. Based on our algorithm, we carry out the detailed analysis including its convergence, its accuracy, its privacy and the trade-off between the accuracy and the privacy level, respectively. It is found that our algorithm preserves the privacy of initial states of all agents in the whole process of consensus computation. The trade-off motivates us to find the best achievable accuracy of our algorithm under the free parameters and the fixed privacy level. Finally, numerical experiment results testify the validity of our theoretical analysis. 展开更多
