'Calling the Judiciary to Account for the Past: Transitional Justice and Judicial Accountability in Nigeria'

Institutional and individual accountability is an important feature of societies in transition from conflict or authoritarian rule. The imperative of accountability has both normative and transformational underpinnings in the context of restoration of the rule of law and democracy. This article argues a case for extending the purview of truth-telling processes to the judiciary in postauthoritarian contexts. The driving force behind the inquiry is the proposition that the judiciary as the third arm of government at all times participates in governance. To contextualize the argument, I focus on judicial governance and accountability within the paradigm of Nigeria’s transition to democracy after decades of authoritarian military rule.

FREQUENCY SELECTIVE SURFACE WITH DUAL BAND SWITCHABLE REFLECTION AND TRANSMISSION CHARACTERISTICS

A pin diode-loaded active doubly periodic flat strip FSS is shown to act as a dynamic screen. It is shown that by means of d.c. bias control, we can utilize the screen in, (1) transmission mode as a dual band electromagnetic shutter, or with the inclusion of a ground plane in reflection mode, (is (2) it dual band refection canceller. (3) an amplitude shift keying (ASK) spatial modulator. The properties of the FSS are characterized using a specially designed parallel plate waveguide simulator that permits normal incidence excitation of the FSS under test. (C) 2009 Wiley Periodicals.

Coherent X-ray production via pulse reflection from laser-driven dense electron sheets

A scheme to obtain brilliant x-ray sources by coherent reflection of a counter-propagating pulse from laser-driven dense electron sheets is theoretically and numerically investigated in a self-consistent manner. A radiation pressure acceleration model for the dynamics of the electron sheets blown out from laser-irradiated ultrathin foils is developed and verified by PIC simulations. The first multidimensional and integral demonstration of the scheme by 2D PIC simulations is presented. It is found that the reflected pulse undergoes Doppler-upshift by a factor 4?z2, where ?z = (1- vz2/c2)-1/2 is the effective Lorentz factor of the electron sheet al ong its normal direction. Meanwhile the pulse electric field is intensified by a factor depending on the electron density of the sheet in its moving frame ne/?, where ? is the full Lorentz factor.

Accountability and Value for Money in Private Finance Initiative Contracts

Within the context of New Public Management (NPM), successive UK governments have claimed that PFI projects provide more accountability, and arguably, more value for money (VFM) than conventional procurement for the public (HM Treasury 1995, 2000, 2003a and 2003b). However, recent empirical research in the UK on PFI has indicated its potential limitations for accountability and VFM (Broadbent, Gill and Laughlin, 2004; Edwards, Shaoul, Stafford and Arblaster, 2004; Shaoul, 2005; and Ismail and Pendlebury, 2006) albeit these are based on either published accounts or a limited number of key stakeholders. This paper attempts to partially redress this gap in the literature by presenting an interesting case of the impact of PFI on accountability and VFM in Northern Ireland's education sector. The findings of this research, based on forty two interviews with a wide range of key stakeholders, suggest that stakeholders have different and often conflicting expectations and the actual PFI accountability and VFM benefits are much more obfuscated than those claimed in Government publications.

Towards Educational Inclusion in a Contested Society: From Critical Reflection to Cultural Action

This paper is written by democratic educators who stand for the idea that is it worth developing, through classrooms and schools, a socially just (egalitarian), anti-discriminatory society where interdependent relationships are valued. This paper significantly develops some of the ideas explored in the authors’ earlier contribution concerned with progress in Northern Ireland towards educational inclusion, and how this might more effectively advance in a post-conflict transforming society. In particular, the paper poses the ‘so what’ question, and it responds by exploring the practical implications of six key ideas thought essential for transforming learning environments supportive of cultural diversity, equity and excellence for all. In addition, it includes examples of how school staff, along with collaborating partners, might utilize these key principles in order to facilitate school improvement.
