Working Paper 60 - Trade Liberalization and Growth: Policy Options for African Countries in a Global Economy
African countries have not embraced trade liberalization in the manner thatother developing regions have. Protectionist measures have taken various forms,including tariffs, quantitative restrictions, exchange controls and downrightimport bans. A significant number of researchers have attributed, in part, thepoor performance of African economies to the protectionist trade practices.Economists have made sustained efforts at cataloguing the welfare costs oftrade barriers and emphasizing the gains from trade in order to advance policiesto reverse protectionist practices. In fact new growth theorists contend thattraditional analysis tended to consistently underestimate the welfare costs ofprotectionism, because they ignored the effects of the introduction of new goodson technological progress, domestic production and growth associated withfree trade. In this paper we conclude that while opening an economy to trademay not provide the desired quick fix, the removal or relaxation of quantitativeimport and export restrictions and lowering of tariffs would result in increasedexports and growth. The dawn of a global economy ushered in by universaltrade liberalization, therefore, need not spell catastrophe for African economiesas is widely feared.“In a major report in the late 1950’s T.K.

Working Paper 35 - Privatization of Public Enterprises in Zambia: An Evaluation of the Policies, Procedures and Experiences
The term Privatization is often loosely used to mean a number of related activities, including any expansion of the scope of private sector activity in an economy and the adoption by the public sector of efficiency enhancing techniques commonly employed by the private sector. While acknowledging that no definition of privatization is water tight, we will define privatization, for the purpose of this paper, as the transfer of productive asset ownership and control from the public to the private sector.1 The transfer of assets can be total, partial or functionary, with the sale being implemented by methods such as private sales, leasing arrangements, employee buy outs and share issues. In Africa, many governments have embraced the idea of privatization, brought to the fore mainly as a part of the adjustment and stabilization programs of the mid-eighties and the nineties. Privatization now frequently features in government policy statements and in conditionalities from donors. The past decade has also seen the World Bank and other donors get increasingly involved in lending operations towards parastatal sector reforms that included privatization components. African countries share a number of common features in relation to the drive towards privatization. For most of these countries, the first twenty years of independence were characterized by rapid growth, driven by favorable terms of trade and high levels of public investments in infrastructure and services. The development of import substituting industries brought in the dramatic rise of parastatal corporations, which were also used as vehicles for increased local participation in the economies. Many governments moved to nationalize existing foreign interests in their countries and also to create new state enterprises to carry out the various production and trading functions. Parastatal corporations rapidly dominated the extractive industries, manufacturing and financial sectors of their economies, and acquired important economic and political status, becoming major sources of employment. The moderate growth experienced in the seventies, however, was quickly reversed by the financial crisis of the early eighties, and associated inefficiencies made parastatal sector reform a major element in the reform efforts implemented by the countries. Zambia was one of the earlier countries to embark on a major privatization exercise as part of its economic reform program started in 1992. Although progress was initially slow, mainly due to the inertia associated with start up activities and generally opposition from interested parties2, the program picked up momentum in the last two years, culminating in the rapid divestiture of public enterprises that many have compared only to privatization programs in eastern Europe. This paper reviews the privatization program in Zambia, highlighting the major tools and mechanisms employed, and the achievements and constraints faced by the authorities in privatizing one of the largest public sectors in Africa. The paper begins with a brief overview of the main economic issues surrounding moves towards privatization of public enterprises.
Trends of Zambia’s tuberculosis burden over the past two decades
Objectives: To study trends in Zambia’s TB notification rates between 1990 and 2010 and to ascertain progress made towards TB control. Methods: Retrospective review of TB notification returns and TB programme reports for the period from 1990 to 2010. Results: Two distinct TB trend periods were identified: a period of rising trends up to a peak between 1990 and 2004 and a period of moderately declining trends between 2004 and 2010. Treatment outcomes improved over the two decades. Data on trends in paediatric TB, TB in prisoners and TB in pregnant women remain scanty and unreliable owing to poor diagnostic capability. There were no data available on trends on drug-resistant TB because of the lack of laboratory services to perform drug sensitivity testing. Conclusions: The period of increasing TB between 1990 and 2000 coincided with an increase in HIV/AIDS. The period of slightly decreasing TB between 2004 and 2010 can be attributed to improved TB care, sustained DOTS implementation and improvement in TB diagnostic services. Newer diagnostics technologies for the rapid diagnosis of active TB cases and for drug-resistant testing, recently endorsed by the WHO, need to be implemented into the national TB programmes to detect more cases and to provide epidemiological and surveillance data from which to obtain an evidence base for guided investments for TB control. Alignment of TB and HIV services is required to achieve improved management outcomes
Body image satisfaction among a sample of black female South African students
Numerous research studies have established a strong relationship between body dissatisfaction
and eating disorders. As more and more young people in South Africa embrace
Western values, the aspiration to attain the Western body ideal of beauty may be putting some
women at risk of developing eating disorders. This study focused on body image satisfaction
among a sample of 150 black South African female university students. Data were collected
using a revised Body Shape Questionnaire (Cooper, Taylor, Cooper, & Fairburn, 1987). The
results showed the majority of the women were satisfied with their body image. However,
there was a minority who engaged in unhealthy eating behaviors. Implications of the findings
are discussed.Web of Scienc
Integration of Services for Victims of Child Sexual Abuse at the University Teaching Hospital One-Stop Centre
Objective. To improve care of sexually abused children by establishment of a "One Stop Centre" at the University Teaching Hospital. Methodology. Prior to opening of the One Stop Centre, a management team comprising of clinical departmental heads and a technical group of professionals (health workers, police, psychosocial counselors lawyers and media) were put in place. The team evaluated and identified gaps and weaknesses on the management of sexually abused children prevailing in Zambia. A manual was produced which would be used to train all professionals manning a One Stop Centre. A team of consultants from abroad were identified to offer need based training activities and a database was developed. Results. A multidisciplinary team comprising of health workers, police and psychosocial counselors now man the centre. The centre is assisted by lawyers as and when required. UTH is offering training to other areas of the country to establish similar services by using a Trainer of Trainers model. A comprehensive database has been established for Lusaka province. Conclusion. For establishment of a One Stop Centre, there needs to be a core group comprising of managers as well as a technical team committed to the management and protection of sexually abused children.Centre for Disease Control and Prevention Zambia; Zambia Society for the Prevention of Child Abuse and Neglect; Zambia Victim Support Unit; UNICEF Zambi
Trends in all-cause mortality during the scale-up of an antiretroviral therapy programme: a cross-sectional study in Lusaka, Zambia.
OBJECTIVE: To follow the trends in all-cause mortality in Lusaka, Zambia, during the scale-up of a national programme of antiretroviral therapy (ART). METHODS: Between November 2004 and September 2011, we conducted 12 survey rounds as part of a cross-sectional study in Lusaka, with independent sampling in each round. In each survey, we asked the heads of 3600 households to state the number of deaths in their households in the previous 12 months and the number of orphans aged less than 16 years in their households and investigated the heads' knowledge, attitudes and practices related to human immunodeficiency virus (HIV). FINDINGS: The number of deaths we recorded - per 100 person-years - in each survey ranged from 0.92 (95% confidence interval, CI: 0.78-1.09) in September 2011, to 1.94 (95% CI: 1.60-2.35) in March 2007. We found that mortality decreased only modestly each year (mortality rate ratio: 0.98; 95% CI: 0.95-1.00; P = 0.093). The proportion of households with orphans under the age of 16 years decreased from 17% in 2004 to 7% in 2011. The proportions of respondents who had ever been tested for HIV, had a comprehensive knowledge of HIV, knew where to obtain free ART and reported that a non-pregnant household member was receiving ART gradually increased. CONCLUSION: The expansion of ART services in Lusaka was not associated with a reduction in all-cause mortality. Coverage, patient adherence and retention may all have to be increased if ART is to have a robust and lasting impact at population level in Lusaka
Drug-Resistant Tuberculosis--Current Dilemmas, Unanswered Questions, Challenges and Priority Needs
Tuberculosis was declared a global emergency by the World Health Organization (WHO) in 1993. Following the declaration and the promotion in 1995 of directly observed treatment short course (DOTS), a cost-effective strategy to contain the tuberculosis epidemic, nearly 7 million lives have been saved compared with the pre-DOTS era, high cure rates have been achieved in most countries worldwide, and the global incidence of tuberculosis has been in a slow decline since the early 2000s. However, the emergence and spread of multidrug-resistant (MDR) tuberculosis, extensively drug-resistant (XDR) tuberculosis, and more recently, totally drug-resistant tuberculosis pose a threat to global tuberculosis control. Multidrug-resistant tuberculosis is a man-made problem. Laboratory facilities for drug susceptibility testing are inadequate in most tuberculosis-endemic countries, especially in Africa; thus diagnosis is missed, routine surveillance is not implemented, and the actual numbers of global drug-resistant tuberculosis cases have yet to be estimated. This exposes an ominous situation and reveals an urgent need for commitment by national programs to health system improvement because the response to MDR tuberculosis requires strong health services in general. Multidrug-resistant tuberculosis and XDR tuberculosis greatly complicate patient management within resource-poor national tuberculosis programs, reducing treatment efficacy and increasing the cost of treatment to the extent that it could bankrupt healthcare financing in tuberculosis-endemic areas. Why, despite nearly 20 years of WHO-promoted activity and >12 years of MDR tuberculosis–specific activity, has the country response to the drug-resistant tuberculosis epidemic been so ineffectual? The current dilemmas, unanswered questions, operational issues, challenges, and priority needs for global drug resistance screening and surveillance, improved treatment regimens, and management of outcomes and prevention of DR tuberculosis are discussed
ConSemblEX: A Consensus-Based Transcriptome Assembly Approach that Extends ConSemble and Improves Transcriptome Assembly
An accurate transcriptome is essential to understanding biological systems enabling omics analyses such as gene expression, gene discovery, and gene-regulatory network construction. However, assembling an accurate transcriptome is challenging, especially for organisms without adequate reference genomes or transcriptomes. While several methods for transcriptome assembly with different approaches exist, it is still difficult to establish the most accurate methods. This thesis explores the different transcriptome assembly methods and compares their performances using simulated benchmark transcriptomes with varying complexity. We also introduce ConSemblEX to improve a consensus-based ensemble transcriptome assembler, ConSemble, in three main areas: we provide the ability to use any number of assemblers, provide a variety of consensus assembly outputs, and provide information about the effect of each assembler in the final assembly. Using five assembly methods both in the de novo and genome-guided approaches, we showed how ConSemblEX can be used to explore various strategies for consensus assembly, such as ConSemblEX-4+, to find the optimum assembly. Compared to the original ConSemble, ConSemblEX improved the de novo assembly performance, increasing the precision by 14% and F1 by 5%, and significantly reducing the FP by 49%. In the genome-guided assembly, ConSemblEX had identical performance to the original ConSemble. We showed that ConSemblEX provides tools to explore how different methods perform and behave depending on the datasets. With the ConSemblEX-select assembly, we further demonstrated that we can improve consensus-based assembly more by choosing optimum overlap sets among different methods. Such information provides the foundation to develop machine learning algorithms in the future to further improve transcriptome assembly performance.
