African-Born Immigrants in U.S. Schools: An Intercultural Perspective on Schooling and Diversity

Despite the significant increase of African-born immigrants in the United States of America, the education system does not recognize their presence and does little to facilitate their integration through the implementation of necessary curricular adjustments. The purpose of this article is to call on multicultural education advocates to endorse the argument for the distinctness of African-born immigrants as a complex cultural group with unique vulnerabilities requiring sensitivity. Organizationally, the paper develops four key points: the current demographic representation of the African population; the absence of African voices in multicultural education scholarship; the salience of multicultural education advocacy in recognizing the essence of African cultures in the western world; and the minimal coverage of African topics in the U.S. curriculum. Two sets of recommendations, curricular and culture-oriented, conclude the argument

CHARACTERIZATIONOF STARCHES FROM RED COCOYAM (Colocasia esculenta) and WHITE COCOYAM (Colocasia antiquorum) CORMELS

Starches of red cocoyam (Colocasia esculenta) and white cocoyam (Colocasia antiquorium) were isolated and their proximate compositions, physicochemical properties and pasting properties were analysed. Ash, moisture and amylose contents of red cocoyam were found to be higher than that of white cocoyam and their protein contents were significantly similar.  No pronounced difference was observed between the X- ray pattern of red cocoyam  and white cocoyam starch samples, and the samples gave the characteristic B pattern of tuber starches. Scanning electron microscopy revealed that starch granules has shell and ellipsoid shapes with heterogeneous sizes.The range of granules were 20 to 150  in width and 30 to 180  in height. Studies on the functional properties also revealed that both swelling capacity and solubility increased with temperature increase. Key words: Cocoyam starch; amylose; Physicochemical properties

Insights into the clinical profile and comorbidities of Factitious Disorder in a multispeciality setting in southwest Nigeria: A cases series and review

Background: Factitious disorder (FD) is an under-recognized and under-diagnosed mental condition. Healthcare professionals often have challenges to diagnose and treating the disorder. As a result, needless and endless medical resources are recommended to assess and evaluate those affected. FD may present as a physical condition, a psychological disorder, or maybe both depending on the prominent symptoms. However, there is a strong correlation between having FD and psychiatric symptoms. Main Text: FD occurs in early adulthood, with a mean age of onset of 25 years in both genders, although with differing demographic features. The lifetime prevalence of FD imposed on oneself in clinical settings is 1.0%, 0.1% in the overall population (ranging between 0.007% and 8.0%) and occurs more in female health care professionals. FD may make up 0.6%–3.0% of psychiatric referrals, and it accounts for 3-5% of doctor-patient contacts. In actuality, 1-2% of hospital admissions and an average of 6-8% of all psychiatric admissions have been underreported. The study aimed to highlight the signs and symptoms of FD identified in a psychiatry department of a multispecialty center and to increase the awareness of health practitioners. A critical review of the literature was done with an emphasis on psychological symptoms. PubMed, Mendeley, and Google Scholar were thoroughly searched and full-text publications of journals from 2010-2021 were included. Conclusion: FD is a diagnostic puzzle that necessitates adequate, prompt medical attention as well as social support because of the potentially fatal consequence. A stronger patient-therapist relationship can strengthen the patient's conscious self-control to minimize the symptoms; therefore the healthcare provider has to be open-minded. For the diagnostic enigma to be removed and for ease of treatment, additional research, increasing awareness among medical professionals and the general public, accurate evaluation, diagnosis, and psychotherapy should be encouraged. These case studies will contribute to the knowledge base of FD and improve the quality of care

"I'm not enough of anything!": The racial and ethnic identity constructions and negotiations of one-point-five and second generation Nigerians

For many African youth, questions of identity are pressing concerns. Many who were born in, but raised outside of their country of origin, known as one-point-five immigrants, and their second generation counterparts (Rong & Brown, 2002), often find themselves at the center of several conflicting cultures. These youth are often challenged in their ability to negotiate and reconcile the varying expectations of their respective racial and ethnic groups. While living in multiple, cultural worlds is the experiences of many minority youth (Phelan et al., 1991), it is uniquely challenging for Black immigrant youth as both their blackness and immigrant background make negotiating their racial and ethnic identities more challenging, than non-black and non-immigrant minority youth. Using qualitative methodology (questionnaires, semi-structured interviews and focus group), this dissertation explored the manner in which eleven, one-point-five and second generation Nigerian college students construct and negotiate their racial and ethnic identities. The research was guided by four broad research questions: (1) How do one-point-five and second generation Nigerian college students describe and experience their interactions with Africans and non-Africans (peers, family, and school personnel)? (2) How do they describe and experience their processes of racial and ethnic identity development? (3) How do their interactions with Africans and non-Africans shape their racial and ethnic identity development? (4) How do they negotiate their racial and ethnic identities among Africans and non-Africans? The results revealed three major findings that characterized the identity experiences of one-point-five and second generation Nigerian immigrants. First, participants often constructed and negotiated their racial and ethnic identities differently within their families, peer groups and the schooling context. Second, participants had to "learn" the meaning of blackness in the U.S. context, which significantly impacted how they experienced their racial identities. Lastly, participants often felt challenged about the authenticity of their Nigerian identity, by both Africans and non-Africans alike. This study provides a significantly more nuanced discussion on the identity constructions and negotiations of one of the fastest growing segments of the diverse black population--African immigrant youth

Development of styrene based imprinted sorbents for selective clean-up of metalloporphyrins in organic media

Most crude oils contain traces of vanadium and nickel complex with porphyrins (VTPP and NTPP) within their asphaltene fraction. Although these metals are only present in trace quantities, they have a significant and detrimental impact on the refining process by degrading the quality of intermediate and end products. Therefore, their selective removal is highly desirable. This thesis presents the development of nickel porphyrin, nickel vanadyl porphyrin imprinted nanofibers and vanadyl porphyrin imprinted polymer (MIP) particles for application as selective sorbents. Computational model based on the combination of molecular dynamics simulations and quantum mechanics was successfully applied to the styrene functional monomer selection. The particle was prepared by bulk polymerization and the nanofibers by a novel approach combining molecular imprinting and electrospinning technology. The morphologies, thermal stabilities and porosities of the imprinted sorbents were studied using SEM, TGA, and BET nitrogen gas adsorption. Chloroform was found to swell the polymer particles to a higher degree than methanol and acetonitrile. The adsorption characteristics of the imprinted sorbents best fitted with Freundlich isotherm model. The imprinted sorbents recorded high extraction efficiencies (EEs) of > 99 % in selectively extracting the metalloporphyrins. The impact of the template on the affinity of recognition for NTPP was evaluated. The results showed that the NTPP adsorption capacity increased as the molar ratio of NTPP to styrene was increased from 1:1 to 3:1. The optimal ratio of template to functional monomer which yielded the best specific affinity and highest recovery (99.9 %) was 3:1. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pentane (PEN) on electro-spinnability of the polymer solutions and the morphological appearance of the nanofibers were investigated. The imprinted nanofibers exhibited the same selectivity specialism for both NTPP and VTPP. A remarkable stability in relation to reusability was observed when imprinted nanofibers were used, as they could be reused nine times without incurring any significant loss in removal efficiency. The results were validated by analysing a certified reference material. The imprinted sorbents were therefore found to be selective sorbents that are well suited for handling trace metals in organic media

Productivity estimation of Ologe Lagoon, Lagos

One of the paradigms in the management of fish resources is that annual yield is a function of water quality. Consequently, the use of shorthand methods for predicting yields from morphological and /or edaphic factors of the water body are most appropriate for tropical multi-species fisheries. In this study, the morpho-edaphic index (MEI) was used to estimate the productivity of Ologe lagoon (Nigeria). The predicted yield was 73.8 kg ha super(-1) yr super(-1) and a comparison with yields in other African waters showed that Ologe lagoon is highly productive. However, its potential is not fully harnessed due to the traditional nature of the fishin

Impact of Microwave Irradiation Energy Levels on Molecular Rotation, Structural, Physicochemical, Proximate and Functional Properties of Potato (Ipomoea batatas) Starch

Starch isolated from potato was subjected to microwave treatment at different energy levels (200 - 800 W) to modify the functional, structural and physicochemical properties, as well as induce molecular rotation of the hydroxyl group on the starch polysaccharide. Proximate analyses revealed that moisture content reduced, while ash, protein, fat and fibre increased after modification. Fourier-transform infrared spectroscopy spectra indicated a strong shift in absorption band of OH from 3441 to 3454 cm-1. Optical light microscopy revealed that starch granules were oval and spherical in shape with hyla on some of the granules. Least gelation concentration reduced following microwave treatment. Compared with the native starch, the pasting parameters of the microwave treated starches decreased, with the exception of set­back viscosity for starch modified at 800 W. Onset temperature (TO), peak temperature (TP) and conclusion temperature (TC) of gelatinization increased in microwave treated starches compared with native potato starch. Also, gelatinization enthalpy increased from 8.21 J/g in native starch to 15.39, 16.36, 17.76 and 38.06 J/g in microwave treated starches at 200, 400, 600, and 800 W, respectively. It was concluded that the energy of microwave irradiation can induce and accelerate molecular rotation of the hydroxyl group on the starch polysaccharide
