Abstract: Background: In sub-Saharan Africa, the DRC ranks among countries with high infant mortality. To solve this problem, the Health Ministry has set up a programme: the use of integrated management childhood illness (IMCI) in community care sites (CCSs) managed by non-health professional persons known as community health workers (CHW). This approach has not yet been integrated into the health pyramid. This is why we chose the Realist Evaluation Approach to evaluate the effectiveness of this programme on Universal Access to care for children under 5 years of age in the DRC. Methods/design: To conduct this exploratory study which is essentially a descriptive case study, we applied the principles of a realist evaluation by context—mechanisms—effects explained in the conceptual framework. The preliminary theory of the programme was elaborated by data collection through a literature review coupled with semi-structured interviews with key informants who were managers of the government programme and technical and financial partners of the programme. Results: IMCI has been evaluated and shown its positive contribution in the reduction of global children mortality. In the DRC, summaries of data collection through a literature review coupled with semi-structured interviews showed the same result. However, under criticism, based on the data collected during this exploratory study, it is promisingly apparent that this programme will achieve the objectives assigned to it through the preliminary theory of the programme. Conclusion: The literature review corroborated the effectiveness of the IMCI programme. The application of this programme in CCS with non-health professionals who are Community Health Workers has been shown to be effective in the DRC. Based on this reality, it was possible to define the basis for a realist evaluation of the effectiveness of the programme in CCS.

Abstract: In attempts to strengthen her cultural exchange, cooperation and diplomatic relations, China has created opportunities for international students and this helps in enhancing diplomatic relations and cultural exchange. The purpose of this study was to examine problems of international students in China and to know the views of cultural/educational attaches of developing countries for Higher Education in China. This study highlights problems and perceptions of international students and experiences such as adapting to a new culture, language problems, financial problems, health services, living and dining and other social and academic problems. The methodology used in this study was quantitative and qualitative to show issues of international students in academics, culture and social environment in China and views of cultural/educational attaches of some developing countries of Asia and Africa. The findings of this paper proved that the extent of problems of international students studying in China and need of more improvement in foreign affairs of China in higher education sector are the need of time. Recommendations for policy implication are integrated to cope up with upcoming challenges for China as destination of international students. The policy recommendations were made on the basis of results to improve foreign affairs of China in Higher Education and in spreading cultural exchanges around the world.
Some Exact Sequences for Toeplitz Algebras of Spherical Isometries
Bebe Prunaru
Mathematics , 2005,
Abstract: A family $\{T_j\}_{j\in J}$ of commuting Hilbert space operators is said to be a spherical isometry if $\sum_{j\in J}T^*_jT_j=1$ in the weak operator topology. We show that every commuting family $\Cal F$ of spherical isometries has a commuting normal extension $\hat{\Cal F}$. Moreover, if $\hat{\Cal F}$ is minimal, then there exists a natural short exact sequence $0\to\Cal C\to C^*(\Cal F)\to C^*(\hat{\Cal F})\to 0$ with a completely isometric cross-section, where $\Cal C$ is the commutator ideal in $C^*(\Cal F)$. We also show that the space of Toeplitz operators associated to $\Cal F$ is completely isometric to the commutant of the minimal normal extension $\hat{\Cal F}$. Applications of these results are given for Toeplitz operators on strictly pseudoconvex or bounded symmetric domains.

Lifting fixed points of completely positive semigroups
Bebe Prunaru
Mathematics , 2011,
Abstract: Let $\{\phi_s\}_{s\in S}$ be a commutative semigroup of completely positive, contractive, and weak*-continuous linear maps acting on a von Neumann algebra $N$. Assume there exists a semigroup $\{\alpha_s\}_{s\in S}$ of weak*-continuous *-endomorphisms of some larger von Neumann algebra $M\supset N$ and a projection $p\in M$ with $N=pMp$ such that $\alpha_s(1-p)\le 1-p$ for every $s\in S$ and $\phi_s(y)=p\alpha_s(y)p$ for all $y\in N$. If $\inf_{s\in S}\alpha_s(1-p)=0$ then we show that the map $E:M\to N$ defined by $E(x)=pxp$ for $x\in M$ induces a complete isometry between the fixed point spaces of $\{\alpha_s\}_{s\in S}$ and $\{\phi_s\}_{s\in S}$.
Asymptotic stability for a class of Markov semigroups
Bebe Prunaru
Mathematics , 2011,
Abstract: Let $U\subset K$ be an open and dense subset of a compact metric space and let $\{\Phi_t\}_{t\ge0}$ be a Markov semigroup on the space of bounded Borel measurable functions on $U$ with the strong Feller property. Suppose that for each $x\in\bdu$ there exists a barrier $h\in C(K)$ at $x$ such that $\Phi_t(h)\ge h$ for all $t\ge0$. Suppose also that every real-valued $g\in C(K)$ with $\Phi_t(g)\ge g$ for all $t\ge0$ and which attains its global maximum at a point inside $U$ is constant. Then for each $f\in C(K)$ there exists the uniform limit $F=\lim_{t\to\infty}\Phi_t(f)$. Moreover $F$ is continuous on $K$, agrees with $f$ on $\partial{U}$ and $\Phi_t(F)=F$ for all $t\ge0$.

Abstract: Introduction: The prevalence of HIV infection amongst pregnant women in Cameroon is 5.6%. Mother-to-child transmission is a major expansion factor. In 2010, Cameroon adopted new strategies pegged to WHO guidelines. Objectives: The objective of this study was to evaluate the implementation of the new guidelines of prevention of mother to-child transmission (PMTCT) of HIV in the Yaoundé Central Hospital and the Yaoundé Teaching Hospital. Methodology: It was a cross sectional descriptive and prospective study over a period of 6 months in Yaoundé. It included all HIV-positive women, doing their antenatal care in the above cited hospitals, and having given their consent. The studied variables included socio demographic features, obstetrical history, the antenatal care, the initiation of anti retroviral (ARV) drugs, the ARV regimen, the number of years on ARV drugs, the mode of delivery and the mother and child outcome. The data was collected using a pre-tested questionnaire. They were obtained by interview of the seropositive pregnant women. Data were analysed using Epi info 3.5.3. Results: We performed 3104 antenatal consultations and 287 women were recruited in the study. The prevalence of HIV infection was 9.24%. The mean age of women was 28.77 (SD: 5.13) years. The women were aged between 20 and 29 years in 51.20%. Amongst the 156 women who knew their status before pregnancy, 109 (70.50%) had their first ANC in the first trimester. All were managed according to the 2010 WHO recommendations on PMTCT of HIV. Amongst the women unaware of their status, 25.20% had their booking ANC in the first trimester, 25.14% started ARVs at 14 weeks, 69.46% at 28 weeks. We had 125 live births, 84.8% by vaginal route, neonatal prophylaxis in all babies was effective. Conclusion: PMTCT of HIV is available and guidelines are well applied in Yaoundé. Late treatment initiation still remains a problem to optimize care.
Evaluation of the Factors Associated with Shift from Pastoral to Agro-pastoral Farming Systems in Trans-Mara West District of Narok County-Kenya

Abstract: The Kenyan Government in partnership with the private sector has set up co-operative societies for marketing livestock and livestock products in Narok County. These co-operatives are supposed to trigger extensive expansion in livestock production. Despite perceived steady incomes, high turnover and ready market for livestock, the pastoral Maasai community is shifting from pastoralism to agro-pastoralism. This community is strongly traditional with much cultural and economic attachment to livestock. The shift brings to question the underlying drives which are not well understood. The drives are diverse, but little is known about their contribution to the engaged shift. The objective of this study was to determine the factors associated with the shift. Stratified proportionate random sampling procedure was used to get the appropriate sample. Data were collected from a sample of 130 households through interview schedule. Heckman two-step model was used to determine the factors associated with the shift. The findings indicated that household decision to shift was enhanced by more frequent group meetings and farmer trainings, declining land sizes, longer distance to watering points, shorter distance to market and more income from off-farm sources of incomes. The agro-pastorals choice to allocate higher proportion of land for crop production compared to livestock production was enhanced by more distance to watering points, low off-farm incomes, private land ownership, larger family, male dominance, more extension services, shorter distance to the market, less years of crop farming and little interaction with the neighbors. Whereas some households shifted out of necessity, others shifted by choice.
Health research systems: promoting health equity or economic competitiveness?

Bulletin of the World Health Organization , 2012, DOI: 10.1590/S0042-96862012000100013
Abstract: international collaborative health research is justifiably expected to help reduce global health inequities. investment in health policy and systems research in developing countries is essential to this process but, currently, funding for international research is mainly channelled towards the development of new medical interventions. this imbalance is largely due to research legislation and policies used in high-income countries. these policies have increasingly led these countries to invest in health research aimed at boosting national economic competitiveness rather than reducing health inequities. in the united states of america and the united kingdom of great britain and northern ireland, the regulation of research has encouraged a model that: leads to products that can be commercialized; targets health needs that can be met by profitable, high-technology products; has the licensing of new products as its endpoint; and does not entail significant research capacity strengthening in other countries. accordingly, investment in international research is directed towards pharmaceutical trials and product development public-private partnerships for neglected diseases. this diverts funding away from research that is needed to implement existing interventions and to strengthen health systems, i.e. health policy and systems research. governments must restructure their research laws and policies to increase this essential research in developing countries.
