Urbanisation and urban expansion in Nigeria
Nigeria’s urban population has increased rapidly over the past 50 years and will continue to grow relatively fast in the coming decades, although how fast is a matter of some dispute. Nigeria’s urban population will nonetheless likely double within the next 30 years, possibly much sooner. The growth of Nigeria’s urban population in both absolute and relative terms has been accompanied by the expansion of existing built-up areas and the emergence of new and identifiably ‘urban’ settlements. This report analyses urbanisation and urban expansion in Nigeria, portraying the dynamics and drivers of urban population growth and the spatial expansion process. The report serves as a detailed ‘baseline’ report for the urban change processes theme of the Urbanisation Research Nigeria (URN) programme – and as a foundation for the later, targeted and more detailed research
Viewing Film from a Communication Perspective: Film as Public Relations, Product Placement, and Rhetorical Advocacy in the College Classroom
Academics approach film from multiple perspectives, including critical, literary, rhetorical, and managerial approaches. Furthermore, and outside of film studies courses, films are frequently used as a pedagogical tool. Their relevance in society as well as their valuable use in the classroom makes them an important and pragmatic medium deserving further attention. The ability of film to be used in a socio-political way may sustain, challenge or change the status quo, which supports studying film as well as teaching students about the power of film. The purpose of this article is to share the development of a course which points out to students how film is used in society. Film theories are discussed, selected films are reviewed, and class assignments related to the theories and movies are summarized. In particular, this course explores films’ relationship to corporate agendas as well as to social justice. This approach to film crosses film studies with rhetoric and public relations connecting the course to other courses often taken by communication majors
Nested cycles in large triangulations and crossing-critical graphs
We show that every sufficiently large plane triangulation has a large
collection of nested cycles that either are pairwise disjoint, or pairwise
intersect in exactly one vertex, or pairwise intersect in exactly two vertices.
We apply this result to show that for each fixed positive integer , there
are only finitely many -crossing-critical simple graphs of average degree at
least six. Combined with the recent constructions of crossing-critical graphs
given by Bokal, this settles the question of for which numbers there is
an infinite family of -crossing-critical simple graphs of average degree
