The electrical resistivity, i.e. electrical resistivity tomography (ERT) and direct current-resistivity sounding (DC-ERS), and ground penetrating radar (GPR) methods were deployed to assess a gully erosion site in Bacoco area of Calabar, Nigeria. The study aims to assess the mechanism and dynamics of the gully erosion conditions in the area based on shallow lithostrati-graphic evaluations. The results revealed good contrast in the operative properties (i.e. electrical resistivity and dielectric permittivity) between competent and weak zones along the profiles close to the gully head. The joint interpretations provided reliable shallow subsurface models and lithologies that consist predominantly of lateritic top cover and sands. However, the ERT model delineates the contrast between lithologies and demarcates the weak zones from the relatively competent zones, in contrast to the responses generated by the GPR technique. This joint interpretation approach minimizes the uncertainty due to the non-uniqueness problems common to the geophysical technique. Also, the geophysical interpretations were constrained using lithologic information from the gully walls and one-dimensional (1-D) DC-ERS inverted model to provide additional validity. Our findings suggest the influence of structural control on gully formation and demonstrate its contribution to the complex interactions with other drivers, such as seepages through porous media and high-energy runoff due to intense rainfall. The rapid, non-invasive and environmentally friendly characteristics of ERT and GPR techniques favour their applicability in assessing shallow subsurface environmental problems.

Since the last quarter of the 20th century, hip hop has become a cultural means of self-expression, entertainment, and empowerment for youths throughout the world. The creative manipulation of verbal and non-verbal codes has been the main vehicle through which the enormous hip hop cultural industry has been sustained and revitalized. This study investigates the creative ingenuity of a group of Naija (Nigerian) youths in Calabar, south-eastern Nigeria, in the creation of a peculiar hip hop brand in the Nigerian Hip Hop Nation (NHHN). Particularly, the study works through Appadurai’s (1996, 2002) theory on migration and the electronic media as agents of modernity to apprehend the emergence and development of hip hop in Nigeria through the example of Calabar hip hop exponents. This article also derives discursive insight from Alim’s (2009) idea of style as a major non-verbal linguistic vector of hip hop to identify and interrogate the creative ingenuity of the Nigerian youths here examined. Our study concludes that through the formation of a creative bond and the manipulation verbal and performance codes from their cultural space these Nigerian youths have established a peculiar brand of hip hop and are contributing to the transnational, multi-vocal Global Hip Hop Nation.
