Studies of Anopheles gambiae s.l (Diptera: Culicidae) exhibiting different vectorial capacities in lymphatic filariasis transmission in the Gomoa district, Ghana
Hilaria Amuzu, Michael D Wilson, Daniel A Boakye
Parasites & Vectors , 2010, DOI: 10.1186/1756-3305-3-85
Abstract: Out of 2553 mosquitoes caught at Mampong, 42.6% were An. gambiae s.l. All 280 identified further by PCR were An. gambiae s.s (275 M and 5 S molecular forms). At Hwida, 112 mosquitoes were obtained; 67 (59.8%) were An. gambiae s.l, comprised of 40 (59.7%) An. melas, 24 (35.8%) An. gambiae s.s (17 and 5 M and S molecular forms respectively) and 3 (4.5%) unidentified. The mean number of teeth for An. melas was 14.1 (median = 14, range = 12-15), An. gambiae s.s., 15.7 (median = 15, range = 13-19) M form 15.5 (median = 15 range = 13-19) and S form 16 (median = 16, range 15-17). The observed differences in teeth numbers were significantly different between An. melas and An. gambiae s.s (p = 0.004), and the M form (p = 0.032) and the S form (p = 0.002).In this study, An. gambiae s.s was the main vector at Mampong and was found to possess significantly more cibarial teeth than An. melas, the principal vector at Hwida. We postulate that the different impact observed after 6 MDAs may be due to An. gambiae s.s exhibiting 'facilitation' at Mampong and at Hwida An. melas the main vector exhibits 'limitation'. Thus it may be necessary to compliment MDA with vector control to achieve interruption of transmission in areas where An. melas may exhibit limitation.Lymphatic filariasis (LF) caused by infections with Wuchereria bancrofti is a debilitating disease which has adverse effects on productivity of infected persons and socioeconomic development of endemic countries [1]. The parasite is transmitted through the bite of infected mosquito species of various genera including, Culex, Anopheles and Aedes. In Ghana, members of the An. gambiae species complex and An. funestus are the principal vectors [2-5] although An. pharoensis has been implicated as a vector [3]. Anopheles gambiae s.l. in Ghana comprises An. gambiae s.s (which has two molecular forms; M and S), An. melas and An. arabiensis [6-8]. Unlike in Asia and East Africa, the Culex species in Ghana are refractory to the parasit

A multifaceted model for designing reading development programmes for L2 learners at tertiary level
Naomi Boakye
Per Linguam : A Journal of Language Learning , 2012, DOI: 10.5785/27-2-111
Abstract: Socio-affective issues are generally acknowledged as important in reading development. However, most intervention programmes focus on cognitive aspects of reading, and do not explicitly accommodate socio-affective factors such as attitude, motivation, interest, and background of students. This paper argues for the inclusion of both cognitive and socio-affective scaffolding in tertiary-level reading development programmes. Based on a number of second language teaching techniques, and grounded in Guthrie and Wigfield’s (2000) engagement model, I propose a multifaceted model on which to map reading instruction/intervention at tertiary level that combines both affective and cognitive factors.
Investigating students’ beliefs about language learning
Naomi Boakye
Per Linguam : A Journal of Language Learning , 2011, DOI: 10.5785/23-2-52
Abstract: There is widespread current interest in language learning studies regarding the extent to which student beliefs can influence the language learning process. Whilst institutions may set up frameworks to enable students to learn languages successfully, many researchers contend that ultimately it is the belief systems of the students themselves which will contribute most to the final outcome of the teaching process. This article explores the idea that the language learning process among students is substantially influenced by their beliefs about this process. A questionnaire based on Horwitz’s (1987) BALLI instrument was used to assess students’ beliefs in terms of language learning, and the issues are discussed within the categories of aptitude, motivation, learning and communication strategies, the nature of learning, and the difficulty of language learning. The results indicate that the beliefs of the students can have a negative influence on their learning strategies which, in turn, affect the success or otherwise of the language learning process. This article thus concludes with suggestions on how to address the negative mindsets of the students concerned in order to create environments that would be more conducive to achieving positive results.

Ghana Medical Journal , 2006,
Abstract: Objectives: To assess the risk of transmission of viral haemorrhagic fevers in northern Ghana. Design: A two-year cross-sectional entomological study was carried out in four communities in the northern part of Ghana. Standard WHO methods were used to collect adult and larvae of Aedes mosquitoes to estimate man-vector contact rates and larval indices. Results: A total of 2804 households were surveyed to estimate larval indices and man-vector contacts of potential vectors of viral haemorrhagic fevers such as Yellow fever and Dengue. Over 56% households in each study site were positive for Aedes larvae. Relatively higher Breteaux index (BI) and Container index (CI) were estimated in Damongo (BI: 180 and CI: 44.8) and Jirapa (BI: 149.7 and CI: 41.5) compared to Tumu (BI: 76.1 and CI: 19.5) and Bolgatanga (BI: 72.4 and CI: 20.6). Man-biting rates of 9.8 and 18.5 bites /man/hour were estimated for Damongo and Jirapa respectively whilst Bolgatanga recorded 10 B/M/H. Generally, man-vector contact rates in all the study sites were higher during the dry season than the wet season. Larval indices showed seasonal variations and the dry season was identified as the high-risk period for transmission of viral haemorrhagic fevers and possible disease outbreaks. No flavivirus was detected in the 2034 Aedes mosquitoes from the study sites by RTPCR. Conclusions: Aedes mosquito larval densities and adult biting rates, in all the study areas were sufficient to promote outbreaks of viral haemorrhagic fevers.

Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.33021
Abstract: In this paper the authors summarize the history of government consolidation successes and failures in Georgia, discuss regionalism and functional consolidation, and address social-structural barriers to unified government. The paper focuses on the 60-year consolidation movement and current unification efforts in Albany-Dougherty County, GA. Since knowing citizen perceptions is vital in understanding the resistance to consolidation, the paper concludes with findings from a 2012 Exit Poll in Dougherty County, GA.
Cardiocladius oliffi (Diptera: Chironomidae) as a potential biological control agent against Simulium squamosum (Diptera: Simuliidae)

Parasites & Vectors , 2009, DOI: 10.1186/1756-3305-2-20
Abstract: Cardiocladius oliffi was successfully reared in the rearing system developed for S. damnosum s.l. and evaluated for its importance as a biological control agent in the laboratory.Even at a ratio of one C. oliffi to five S. squamosum, they caused a significant decrease in the number of adult S. squamosum emerging from the systems (treatments). Predation was confirmed by the amplification of Simulium DNA from C. oliffi observed to have fed on S. squamosum pupae. The study also established that the chironomid flies could successfully complete their development on a fish food diet only.Cardiocladius oliffi has been demonstrated as potential biological control agent against S. squamosum.Human onchocerciasis has been controlled as a disease of public health and socio-economic importance in parts of West Africa covered by the Onchocerciasis Control Programme (OCP), primarily through vector control. However, the blackfly vectors (various sibling species of Simulium damnosum Theobald complex) were not eliminated. Therefore, after cessation of vector control, re-colonization of the onchocerciasis-freed zones by the vectors has occurred, and this could lead to recrudescence of the disease if there are residual infections in the human population. These fears were allayed when mass treatment with ivermectin and the resultant massive reductions in microfilariae indicated that long-term treatments could lead to interruption of transmission. The return of the flies was therefore considered to pose only a biting nuisance and not a health risk, although anaphylactic shock, probably resulting in persons exposed to mass biting of two Simulium species in the English Midlands, has been reported [1].There are no reports of the economic impact of the nuisance of S. damnosum s.l. in monetary terms [2]. However, Jamnback [3] reported that, in areas of major developmental projects, the incessant bites could be a serious threat to economic success. In C?te d'Ivoire, it was reported in the pres

Ghana Medical Journal , 2006,
Abstract: Background: Hard tissue defects in the maxillofacial region due to trauma or ablative surgery result in functional and cosmetic problems. State-of-theart methods for reconstruction include the use of vascularised tissue. Objective: To review our results with the use of non-vascularised rib grafts for maxillofacial reconstruction. Method: Patients who underwent maxillofacial reconstruction using rib at the Komfo Anokye Teaching Hospital during 1996-2004 were studied. The technique for rib harvest and implantation of the graft was standardized. Clindamycin was administered peri-operatively and the harvested rib was temporarily stored in clindamycin/saline before implantation. The graft was successful if it survived beyond 6 months after placement. Follow- up was for at least 12months postoperatively. Results: A total of 29 patients were studied. The indications for grafting included ameloblastoma, malignant disease, cyst, ankylosis, and trauma. Either rib bone only or with cartilage were used. In 90% of patients (26/29) the graft healed uneventfully. Two patients had dehiscence of the wound with exposure of the graft intraorally within two weeks of surgery and were successfully managed with antibiotics. Conclusion: Free autogenous rib was successfully used to reconstruct defects in the maxillofacial region. Further stabilization of the graft by intermaxillary fixation and the prophylactic use of clindamycin may have helped to minimize complications.

African Journal of Reproductive Health , 2011,
Abstract: The Barekuma Collaborative Community Development Project (BCCDP) performed a study regarding family planning in communities in the Barekese sub-district near Kumasi, Ghana in July 2010. Eighty-five women, ages 15-49 years, in three communities were interviewed with a modified version of the 2008 Ghana Demographic and Health Survey. While virtually all women recognized at least one family planning method, half of all recent or current pregnancies were unintended and 20 percent of women had a previous abortion. Unexpectedly, 27 percent of women had misused norethisterone tablets (Primolut N or “N-tablets”), a synthetic progesterone, as emergency contraception. Women had a variety of concerns about family planning methods, including one-third having a fear of side effects for hormonal methods (particularly heart palpitations), as well as unfamiliarity with and particular aspects they did not like for most methods. However, women were interested in learning more about side effects as well as modern fertility awareness-based methods. There is an urgent need for interventions aimed at regulating and implementing the correct use of Primolut N tablets, addressing real and perceived side effects of family planning practices through properly trained community health nurses and introducing modern methods of fertility awareness such as Standard Days Method and the Two-day Method in the Barekese sub-district. Le Barekuma Collaborative Community Development Project(BCCDP) a mené une étude concernant la planification dans des communauté dans les sous districts de Barakese , près de Kumasi, Ghana au mois de juillet 2010. Quatre-vingt-cinq femmes agées de 15-49 ans dans trois communautés ont été enquêtées à l'aide d'une version modifiée de l'Enquête Démographique et de Santé réalisée au Ghana. Tandis que presque toutes les femmes ont reconnu au moins une méthode de la planification familiale, la moitié de toutes les grossesses récentes ou actuelles étaient non voulues et 20% des femmes ont déjà eu un avortement. Alors qu'on ne s'y attendait pas, 27% des femmes ont abusé des comprimés de norethistérone (Primolut N ou Comprimés-N ) une progestérone synthétique, comme une contraception d'urgence. Les femmes avaient pas mal de soucis concernant les méthodes de la planification familiale, y compris un tiers qui avaient peur des effets secondaires à l'égard des méthodes hormonales (surtout les palpitations cardiaques, aussi bien que la non familiarité avec des aspects particuliers qu'elles n'aimaient pas à l'égard des plupart des méthodes. Néanmoins, les femmes s'intéressaient à mieux se renseigner sur les effets secondaires aussi bien que sur les méthodes de la fertilité qui sont basées sur la sensibilisation. Il y a un besoin urgent d'interventions qui visent le contr le et la mise en oeuvre d'une utilisation des comprimés de Primolut N, de s'occuper des effets secondaires réels ou percus des pratiques de la planification familiale à travers des infirmières de l
