How older adults use cognition in sentence-final word recognition

This study examined the effects of executive control and working memory on older adults’ sentence-final word recognition. The question we addressed was the importance of executive functions to this process and how it is modulated by the predictability of the speech material. To this end, we tested 173 neurologically intact adult native English speakers aged 55–84 years. Participants were given a sentence-final word recognition test in which sentential context was manipulated and sentences were presented in different levels of babble, and multiple tests of executive functioning assessing inhibition, shifting, and efficient access to long-term memory, as well as working memory. Using a generalized linear mixed model, we found that better inhibition was associated with higher accuracy in word recognition, while increased age and greater hearing loss were associated with poorer performance. Findings are discussed in the framework of semantic control and are interpreted as supporting a theoretical view of executive control which emphasizes functional diversity among executive components.     

Pentecostal Movements,Islam and the Contest for Public Space in Northern Nigeria

The article considers the changing relationship between independent Pentecostal and charismatic groups and radical Islamic movements in Northern Nigeria between the 1970s and the early years of the twenty-first century. All these groups, be they Christian or Muslim, represent a new dimension in religious fundamentalism in contemporary Nigeria. In spite of being internal revivalist groups within their respective religious traditions, they reflect negative attitudes toward each other. Their relationship has been marked by continuous competition for public space. In the late 1980s and early 1990s, the demonization of Islamic groups was a feature of Pentecostal discourse. Through their involvement in political activities under the umbrella of the Christian Association of Nigeria (CAN), evangelicals and Pentecostals developed a common front in the face of Muslim fundamentalism.     

Influence of liquid state diffusion on joint microstructure developed during transient liquid phase bonding of dissimilar superalloys

Theoretical prediction of the influence of liquid-state diffusion on the joint microstructure developed during transient liquid phase (TLP) bonding of dissimilar superalloys, based on asymmetric numerical simulation model, is experimentally verified. A new understanding of the diffusional solidification mechanism during TLP bonding has enabled the formation of a single-crystal (SX) joint microstructure between dissimilar polycrystalline and SX substrates, which is considered unachievable by conventional TLP bonding theoretical models.
