'The Judiciary and Constitutionalism in Transitions: A Critique'

The article critically analyses the role of the Nigerian courts in mediating resultant tensions in the post-authoritarian transition period. In doing this, I examine jurisprudence emanating from the courts on some serious inter-governmental disputes, as well as decisions bordering on individual and group rights, particularly those connected to the transition process. The dynamics of democratic transition in Nigeria after decades of military rule dictates the inevitability of these disputes. The military left a legacy of systemic distortion and institutional dysfunctions which constitute formidable challenges to the transitioning society. The article argues a case for a purposive jurisprudential approach to resolving the ensuing tensions which typically threaten the viability of the transition.

Energy levels, radiative rates, and electron impact excitation rates for transitions in OVII

Aims.
In this paper we report calculations for energy levels, radiative rates, and electron impact excitation rates for transitions in O vii.
Methods.
The grasp (general-purpose relativistic atomic structure package) is adopted for calculating energy levels and radiative
rates. For determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code (darc) and the
flexible atomic code (fac) are used.
Results.
Oscillator strengths, radiative rates, and line strengths are reported for all E1, E2, M1, and M2 transitions among the lowest
49 levels of O vii. Collision strengths have been averaged over a Maxwellian velocity distribution, and the resulting effective collision
strengths are reported over a wide temperature range below 2 × 106 K. Additionally, lifetimes are also listed for all levels.
Key words.

The Hindered Self-Help: Housing Policies, Politics And Poverty In Kolkata, India

The housing dimension in Kolkata has been changing in recent years. Since 1991, the city has initiated housing reform that has taken many forms and manifestations characterized by the reduction in social allocation, cutbacks in public funding and promotion of a real estate culture in close partnership between the state and private actors. There has been increasing concern about the housing condition of the poor in the deserted slums and bustee settlements amidst the evident ‘poor blindness’ in housing and investment policies. Against this background the paper discusses self-help housing in Kolkata. It seeks to answer a simple question – why the concept of self-help has not been recognised as a viable policy option for a city with widespread slums and bustee settlements by visiting the complex urban context of Kolkata set within the city's politics, poverty and policies. The paper concludes that there is a need to recognise the existing structural duality in the city and support self-help housing as a parallel housing approach.

Effective collision strengths for transitions of Ni XVII

Electron impact excitation collision strengths are required for the analysis and interpretation of stellar observations. This calculation aims to provide fine structure effective collision strengths for the Ni XVII ion using a method which includes contributions from resonances. A DARC calculation has been performed, involving 37 J pi states. The effective collision strengths are calculated by averaging the electron collision strengths over a Maxwellian distribution of electron velocities. The non-zero effective collision strengths for transitions between the fine structure levels are given for electron temperatures (T(e)) in the range log(10) T(e)(K) = 4.5 - 8.5. Data for several transitions from the ground state are discussed in this paper.
