Data for the air pollutants were obtained from the Imo State Environmental Protection Agency. The Spearman's ranked order correlation technique was used to investigate the...

Summary Tinea capitis continues to be a common problem of infancy and childhood, particularly among those living in unhygienic crowded conditions. The prevalence and aetiology of tinea capitis have not been well defined in Anambra state of Nigeria – hence the need to undertake this study. A total of 47 723 primary school children residing in different regions of the State was screened for tinea capitis between 2002 and 2005. Of this number, 4498 (9.4%) had tinea capitis. The highest...

Abstract The projected climate‐change signal in simulations by the Conformal‐Cubic Atmospheric Model (CCAM) over southern Africa is presented, with particular emphasis on the projected changes in circulation over the region. Current (1975–2005) and future (2070–2100; A2 scenario) climate simulations are used for this purpose. In the austral winter of the future climate, frontal rain bands are displaced to the south as a result of the subtropical high‐pressure belt intensifying to the south...

Abstract This essay addresses a call for research involving African Americans to interpret data from the historical, contemporary, and cultural experiences of African Americans. The essay argues for a science education research approach that explicitly considers the positionality of African Americans in the United States. This positionality involves the negotiation of three distinct and conflicting realms of experience that pertain to oppression, African‐rooted Black culture, and the...

The usability of any tool or system has to be viewed in terms of the context in which it is used, and its appropriateness to that context. According to the ISO definition of usability, the context of use includes the users, tasks, equipment (hardware, software and materials), and the physical and social environments in which a product is used. Context analysis provides a framework to ensure that all factors which may affect the usability of a product are considered.

This research investigates the role of experience in relation to teachers’ beliefs and practices. The study adopted a social‐cultural constructivist perspective using an interpretive approach. The research was guided by teachers’ interpretations of their experiences related to teaching science through Science‐Technology‐Society (STS) issues. These interpretations are re‐interpreted to find meaningful conceptual categories (grounded in the data) from which to build a model to understand the...

The Five-Factor Model (FFM) of personality is one of the prominent models in contemporary psychology and defines personality in terms of five broad factors, namely, Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. Recent research, however, questions the applicability of the FFM in non-Western cultures, suggesting that it is not exhaustive enough and that it does not account for some other personality factors, most notably Individualism/Collectivism....
