Schooling pupils with disabilities in Franceand Cameroon: a comparative analysis
2016
International audience; he right to education and academic success of all are the concerns of all time regardless of the contexts (UNESCO, 2008). Unfortunately, despite the solemn affirmations and commitments to education for all and inclusive education, the question of the effectiveness of including all-out pupils with disabilities remains a relatively unexplored topic. Inclusive education implies a paradigm shift in which the conditions for success are based on the ability of the school to adapt to the diversity of the public it hosts (Plaisance, Belmont, Verillon et al., 2007; Dyson, Millward et al., 1999). Some researchers (Armstrong, 2001; Ainscow, 2003) showed that if educational poli…
Furoquinolines and dihydrooxazole alkaloids with cytotoxic activity from the stem bark of Araliopsis soyauxii.
2018
Abstract Two new furoquinoline alkaloids, maculine B (1) and kokusaginine B (2) and one new dihydrooxazole alkaloid, veprisazole (3), along with four known compounds namely, N13-methyl-3-methoxyrutaecarpine (4), flindersiamine (5), skimmianine (6) and tilianin (7) were isolated from the methanol extract of the stem bark of Araliopsis soyauxii Engl. by various chromatographic methods. Their structures were determined using spectrometry and spectroscopic techniques including NMR and MS. The cytotoxicity of the new compounds compared to that of doxorubicin, the reference anticancer compound, was determined on a panel of nine cancer cell lines including sensitive and drug resistant phenotypes. …
Anticancer activities of six selected natural compounds of some Cameroonian medicinal plants.
2011
BACKGROUND: Natural products are well recognized as sources of drugs in several human ailments. In the present work, we carried out a preliminary screening of six natural compounds, xanthone V(1) (1); 2-acetylfuro-1,4-naphthoquinone (2); physcion (3); bisvismiaquinone (4); vismiaquinone (5); 1,8-dihydroxy-3-geranyloxy-6-methylanthraquinone (6) against MiaPaCa-2 pancreatic and CCRF-CEM leukemia cells and their multidrug-resistant subline, CEM/ADR5000. Compounds 1 and 2 were then tested in several other cancer cells and their possible mode of action were investigated. METHODOLOGY/FINDINGS: The tested compounds were previously isolated from the Cameroonian medicinal plants Vismia laurentii (1,…
La povertà rurale in Africa Sub-sahariana: il caso del Dipartimento della Lekie in Camerun
2021
Questo articolo mette in rilievo le caratteristiche della povertà rurale in Africa sub-sahariana in generale, e nel Dipartimento della Lekie in Camerun in particolare. Il suo interesse sta nel fatto che per meglio combattere la povertà, bisogna innanzitutto capire la sua vera natura e le sue particolari caratteristiche sul territorio d’intervento. Questo studio mira dunque a offrire alla comunità scientifica nonché a vari portatori d’interesse un quadro di riferimento per la definizione di politiche economiche efficaci contro la povertà sul territorio del Dipartimento della Lekie. L’indagine svolta sul cosiddetto territorio ha rilevato, tramite un’analisi descrittiva, che le popolazioni del…
Investigating teacher leadership in Cameroon secondary education : a case of two public schools
2018
Teacher leadership is crucial in improving schools and enhancing student learning. In Cameroon, the hierarchical nature of leadership and the internal school structures encourage the partition of roles and responsibilities and a clear separation of power and authority. Teachers in Cameroon work within a more imposed system, where the national curriculum is design and impose on them. As a result, teachers do not perform activities geared towards leadership. To improve on teacher leadership practices in Cameroon and learn from exemplar systems (e.g., Finland), it is important to examine how teacher leadership is practiced and how it can be improved. Accordingly, the purpose of this study is t…
The Extractive Industries Transparency Initiative (EITI) in Cameroon : realities and prospects
2010
For a long time, Cameroon was a success story in the context of Africa’s development. Unfortunately, the economic crises of the eighties and early nineties led to the failure of the development strategies that had been pursued until then, resulting in a severe deterioration of the country’s economy and the living standards of the Cameroonian people (Mentan, 2003). However, this country possesses significant oil wealth which if properly managed can generate abundant revenue to boost economic growth and fund anti-poverty measures. In 2005, Cameroon adhered to the Extractive Industries Transparency Initiative (EITI). A proper implementation of this initiative will improve transparency in the c…
Clinical features and epidemiology of cutaneous leishmaniasis and Leishmania major/HIV co-infection in Cameroon: results of a large cross-sectional s…
2011
Cutaneous leishmaniasis (CL) is endemic in Central Africa, including Cameroon. However, data on its prevalence and co-infection with HIV are scarce. Here we present the results of a large cross-sectional study reporting the prevalence, clinical features and species identification of CL and HIV co-infection in northern Cameroon. A total of 32 466 subjects were clinically screened for CL during a door-to-door survey, followed by parasitological diagnosis in the field laboratory. Amongst the subjects surveyed, 146 (0.4%) were diagnosed with active CL. Seven (4.8%) of these 146 CL patients tested positive for HIV-1 and/or HIV-2. The number of lesions per CL patient ranged from 1 to 20. Three of…
Jusqu'où peut-on comparer les apprentissages scolaires ?
2007
The pertinent review for the early knowledge learning in school and their links with quality matters is a complex issue, expressly in a comparative approach when crossing the variety on the range for economic development. But the increasingly frequent reference for a universal basic knowledge, in a connection with a claim concerning a global convergence, as a necessity in self determination for everyone to apply for a minimum level in literacy, raises the question whereby the comparative description of the factors of effectiveness of the school. In this note, the objective is only centred on the concerns for a comparison in measurement relating to results of a common school test led to pupi…
Genetic Diversity of HIV-1 Non-B Strains in Sicily: Evidence of Intersubtype Recombinants by Sequence Analysis ofgag,pol, andenvGenes
2007
The molecular epidemiology of HIV-1 strains in Sicily (Italy) was phylogenetically investigated by the analysis of HIV-1 gag, pol, and env gene sequences from 11 HIV-1 non-B strains from 408 HIV-1-seropositive patients observed from September 2001 to August 2006. Sequences suggestive of recombination were further investigated by bootscanning analysis of various fragments. Overall, we identified several second-generation recombinant (SGRs) strains, which contained genetic material of CRF02_AG in at least one gene. Notably, three individuals were found to be infected with subsubtype A3, and one of them showed genetic recombination with subsubtype A4. The current study emphasizes the genetic a…
Transnacionālās uzņēmējdarbības loma jaunattīstības valstīs: Kamerūnas gadījums
2021
Starpnacionālās uzņēmējdarbība ietvaros cilvēki cenšas īstenot uzņēmējdarbības mērķus to valstu starpā, kurās viņi atrodas, mobilizējot abās sabiedrībās pieejamos resursus veidos, kas atbilst viņu uzņēmējdarbības mērķiem. Globalizācijas dēļ cilvēki var atklāt jaunas kultūras, kopienas un iegūt zināšanas. Tajā pašā laikā cilvēki ar uzņēmējdarbības iniciatīvu uzsāk uzņēmējdarbību tīklā starp savu mītnes valsti un saņēmējvalstīm, izmantojot abpusēji pieejamos resursus. Šajā darbā tiek pētīta starpnacionālā uzņēmējdarbība Kamerūnā, lai izprastu tās ietekmi uz uzņēmumu izveidi un ekonomisko ietekmi jaunattīstības valstī. Galvenā uzmanība tiek pievērsta starptautiskai uzņēmējdarbībai Āfrikas jaun…
