Confidence in the health system and health insurance enrollment among the informal sector population in Lusaka, Zambia
No full textBackground: To improve equitable access to quality essential services and reduce financial hardship, low-and-middle-income countries are increasingly relying on prepayment strategies such as health insurance schemes. Among the informal sector population, confidence in the health system to provide effective treatment and trust in institutions can play an important role in health insurance enrollment. The objective of this study was to examine the extent to which confidence and trust affect enrollment into the recently introduced Zambia National Health insurance. Methods: We conducted a regionally representative cross-sectional household survey in Lusaka, Zambia collecting information on demographics, health expenditure, ratings of last health facility visit, health insurance status and confidence in the health system. We used multivariable logistic regression to assess the association between enrollment and confidence in the private and public health sector as well as trust in the government in general. Results: Of the 620 respondents interviewed, 70% were enrolled or planning to enroll in the health insurance. Only about one-fifth of respondents were very confident that they would receive effective care in the public health sector ‘if they became sick tomorrow’ while 48% were very confident in the private health sector. While confidence in the public system was only weakly associated with enrollment, confidence in the private health sector was strongly associated with enrollment (Adjusted odds ratio (AOR) 3.40 95% CI 1.73 – 6.68). No association was found between enrollment and trust in government or perceived government performance. Conclusions: Our results suggest that confidence in the health system, particularly in the private health sector, is strongly associated with health insurance enrollment. Focusing on achieving high quality of care across all levels of the health system may be an effective strategy to increase enrollment in health insurance
Purchasing for high-quality care using National Health Insurance: evidence from Zambia
No full textImproving the quality of care is essential for progress toward universal health coverage. Health financing arrangements offer opportunities for governments to incentivize and reward improvements in the quality of care provided. This study examines the extent to which the purchasing arrangements established within Zambia's new National Health Insurance can improve equitable access to high-quality care. We adopt the Strategic Purchasing Progress and the Lancet Commission for High-Quality Health Systems frameworks to critically examine the broader health system and the purchasing dimensions of this insurance scheme and its implications for quality care. We reviewed policy documents and conducted 31 key-informant interviews with stakeholders at national, sub-national, and health facility levels. We find that the new health insurance could boost financial resources in higher-levels of care, improve access to high-cost interventions and improve care experiences for its beneficiaries as well as integrate the public and private sectors. Our findings also suggest that the health insurance will likely improve some aspects of structural quality but may not be able to influence process and outcome measures of quality. It is also not clear if health insurance will improve efficiency in service delivery, and whether benefits realized will be distributed in an equitable manner. These potential limitations are attributable to the existing governance and financial challenges, low investments in primary care, and shortcomings in the design and implementation of the purchasing arrangements of health insurance. Although Zambia has made progress in a short span, there is a need to improve its provider payment mechanisms, and monitoring and accounting for higher quality of care
Executive compensation, corporate governance and corporate performance: A simultaneous equation approach
No full textThis paper investigates the association between executive compensation and performance. It uniquely utilises a comprehensive set of corporate governance mechanisms within a three-stage least squares (3SLS) simultaneous equation framework. Results based on estimating a conventional single equation model indicate that the executive pay and performance sensitivity is relatively weak, whereas those based on estimating a 3SLS model generally suggest improved executive pay and performance sensitivity. Our findings highlight the need for future research to control for possible simultaneous interdependencies when estimating the executive pay and performance link. The findings are generally robust across a raft of econometric models that control for different types of endogeneities, executive pay and performance proxies.<br/
Malaria control policies and strategies in Ghana: the level of community participation in the intersectoral collaboration
No full textFor more than a century now, malaria has been a major public health problem in Ghana which consequently has been one of the country’s sources of underdevelopment due to economic losses, high rate of morbidity and mortality. Faced with this problem, the last ten years has seen a commitment from the Ghanaian government to address the issue by establishing a policy that would transform the way the disease is prevented and controlled. The transformation of the management of the disease by the use of intersectoral collaboration strategy (ISC) was to ensure the inclusion of the grass root community members who were hitherto excluded from participating in policymaking process of the national malaria control programme (NMCP) activities. The idea was that by allowing the communities to participate, members would be empowered to have ownership of programme activities, could accept the challenges associated with the control of the disease, and above all contribute more effectively to the success of the policy goal of minimising the persistence of malaria in Ghana.However, over ten years now, no systematic study has been done to access the extent to which this policy goal has been rhetoric or a reality. This thesis therefore seeks to examine this vision by investigating the extent to which the community members are allowed by the health authorities to participate in this policy strategy. Drawing on the case studies in the rural and urban districts in Ghana, the practical reality of the degree of community participation in ISC has been explored. In addition, the roles played by the community members in malaria control programme activities were examined with the aim of understanding the importance of communities in malaria control efforts. Finally, the barriers to participation as well as the extent of the institutional involvement in ISC and its possibility to facilitate community participation have also been examined.Overall, the evidence from the study findings demonstrated that the established strategy of ISC has not significantly promoted community participation in the NMCP activities. While the communities were consulted on malaria issues, they were often excluded from the final decision-making on issues that needed to be acted upon. Consequently, the communities have no guarantee that their views will be considered during the final deliberation in which they have little or no part to play. In spite of this, the study found that through various ways, the community members had been playing a number of significant roles in the control activities. These roles included: supporting health staff in their outreach services, contributing in managing the environment, providing assistance in the monitoring and evaluation of malaria programmes and finally assisting victims to cope with the disease. The findings also indicated that without a number of barriers, certain existing contextual factors (e.g. good level of horizontal integration and political structures and social-cultural institutions) potentially could have contributed to the community participation. From the views of health officials, these barriers were the powers of central bureaucratic structures and lack of resources whilst the community members perceived poverty, lack of support from the local health authorities, the precarious nature of their livelihood and traditional culture as those factors that have undermined participation. These barriers were structural and as such tackling any one barrier in isolation was not likely to solve the malaria problem. Besides, no one government sector, on its own, through participation, could make it possible for the community members to have a full ownership of the control programme activities as well as develop a culture of malaria prevention and control.Thus in the context of the study sites, the study concluded that although there is no evidence to suggest that ISC has enhanced full community participation, the strategy should be commended. In reality, the finding indicated that through ISC strategy many sectors including the community have become more aware of malaria problem and communicate more to solve the problem together. In the light of this, the study finds joint action in the form of ISC across many government sectors as a potential solution if these barriers are to be dealt with in a more strategic way rather than a piecemeal manner.In conclusion, it has been argued that with such a complex problem like malaria, ISC with community participation in policy making process is both a necessary and sufficient condition in reducing malaria persistence in the study sites. The health sector must work collaboratively with other related sectors and it is with such collaborative efforts that can change the attitudes of the community members. Changes in behavioural attitudes are paramount if communities’ activities that affect the environment and promote breeding of mosquitoes are to be minimised. Thus with ISC strategy, what is further needed are: proper control planning that will ensure better coordination amongst sectors, adequate resources and behavioural change by the community members themselves. Each of these factors, I believe should not work in isolation, rather must work together otherwise malaria persistence in Ghana will not go away anytime soon
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Optimal load sharing in reconfigurable battery systems using an improved model predictive control method
No full textOptimal load sharing through balancing has the potential of increasing the lifetime and capacity of the lithiumion battery. This paper presents a model predictive control (MPC) approach for optimal load sharing for lithium-ion multi-battery systems in electric vehicles. The primary objective is the satisfaction of the motoring or regenerative load power demand. Secondary objectives are state of charge (SoC) and temperature balancing amongst battery units. An advanced electro-thermal model which includes a two-state thermal model is used, which leads to better performance in terms of temperature balancing and control. The proposed MPC controller, which reduces battery degradation, is validated through simulations under the urban dynamometer driving schedule. The results showed satisfactory power tracking, and SoC and temperature balancing

John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
