Peri-urban Area (peri-urban + area)
Selected AbstractsComparative effects of deltamethrin and Neem kernel solution treatments on Diamondback moth and Cotesia plutellae (Hym., Braconidae) parasitoid populations in the Cotonou peri-urban area in BeninJOURNAL OF APPLIED ENTOMOLOGY, Issue 3-4 2000A. E. Goudegnon A comparison between deltamethrin and Neem kernel solution treatments on Plutella xylostella (L.) populations was made in the Cotonou peri-urban area. Diamondback moth populations were 10 times larger in deltamethrin plots, than in Neem plots after treatment. The number of marketable cabbages from Neem-treated plots was 1.5 times greater than the number from deltamethrin-treated plots. There was no apparent effect of either treatments on Cotesia plutellae (Kurdjumov) populations, the only parasitoid of the pest that was present in the area. [source] Risk factors for early lactation problems among Peruvian primiparous mothersMATERNAL & CHILD NUTRITION, Issue 2 2010Susana L. Matias Abstract The aim of this study was to determine the incidence and risk factors for early lactation problems [suboptimal infant breastfeeding behaviour (SIBB), delayed onset of lactogenesis (OL) and excessive neonatal weight loss] among mother,infant pairs in Lima, Peru. All primiparous mothers who gave birth to a healthy, single, term infant at a government hospital in a peri-urban area of Lima during the 8-month recruitment period were invited to participate in the study. Data were collected at the hospital (day 0) and during a home visit (day 3). Infant breastfeeding behaviour was evaluated using the Infant Breastfeeding Assessment Tool; SIBB was defined as ,10 score. OL was determined by maternal report of breast fullness changes; delayed OL was defined as perceived after 72 h. Excessive neonatal weight loss was defined as ,10% of birthweight by day 3. One hundred seventy-one mother,infant pairs participated in the study. SIBB prevalence was 52% on day 0 and 21% on day 3; it was associated with male infant gender (day 0), <8 breastfeeds during the first 24 h (days 0 and 3), and gestational age <39 weeks (day 3). Delayed OL incidence was 17% and was associated with infant Apgar score <8. Excessive neonatal weight loss occurred in 10% of neonates and was associated with maternal overweight and Caesarean-section delivery. Early lactation problems may be influenced by modifiable factors such as delivery mode and breastfeeding frequency. Infant status at birth and maternal characteristics could indicate when breastfeeding dyads need extra support. [source] Witchcraft and the limits of mass mediation in MalawiTHE JOURNAL OF THE ROYAL ANTHROPOLOGICAL INSTITUTE, Issue 2 2007Harri Englund This article explores what the study of witchcraft in an African setting can contribute to current efforts to theorize mass mediation and the imagination it fosters. Recent ethnographies of witchcraft discourses in Africa have continued to associate them with the formation of small-scale groups, but evidence from Malawi shows how they enable subjects to imagine sociality on an indeterminate scale. The article deploys the concept of mediation to theorize how in this imagination witches mediate sociality as the unrecognized third parties who give rise to recognized social relationships of varying scale. The ethnography of witchcraft discourses in radio broadcasting and an impoverished peri-urban area demonstrates not only their relevance to apparently disparate contexts but also their potential to exceed the impact of the mass media. The case of a violent conflict involving Pentecostal Christians, South Asian entrepreneurs, Muslims, and members of a secret society provides an example of how arguments about witchcraft had a greater impact on the popular imagination than a mass-mediated report of the same conflict. The article concludes by arguing that witchcraft discourses should be accorded weight equal to the mass media in theorizing the imagination. [source] Genetic Admixture in Brazilians Exposed to Infection with Leishmania chagasiANNALS OF HUMAN GENETICS, Issue 3 2009Nicholas A. Ettinger Summary Visceral leishmaniasis (VL) in northeast Brazil is a disease caused by infection with the protozoan Leishmania chagasi. Infection leads to variable clinical outcomes ranging from asymptomatic infection to potentially fatal disease. Prior studies suggest the genetic background of the host contributes to the development of different outcomes after infection, although it is not known if ancestral background itself influences outcomes. VL is endemic in peri-urban areas around the city of Natal in northeast Brazil. The population of northeast Brazil is a mixture of distinct racial and ethnic groups. We hypothesized that some sub-populations may be more susceptible than others to develop different clinical outcomes after L. chagasi infection. Using microsatellite markers, we examined whether admixture of the population as a whole, or markers likely inherited from a distinct ethnic background, differed between individuals with VL, individuals with an asymptomatic infection, or individuals with no infection. There was no apparent significant difference in overall population admixture proportions among the three clinical phenotype groups. However, one marker on Chr. 22 displayed evidence of excess ancestry from putative ancestral populations among different clinical phenotypes, suggesting this region may contain genes determining the course of L. chagasi infection.
