The Rise and Fall of the Basic Income Grant Campaign: Lessons from Namibia
Namibia is still characterised by deep socio-economic inequalities, as economic structures have remained largely intact after independence. Poverty is still widespread and unemployment has remained high with women and youth being particularly affected. In 2002, the Namibian government’s Tax Commission proposed a universal cash grant as the most effective way to fight poverty and to reduce inequality. In 2004, the Basic Income Grant (BIG) Coalition was formed consisting of churches, trade unions and non-governmental organisations (NGOs) in support of the proposed grant. It implemented a pilot project to practically demonstrate the effects of the grant. The chosen location was the village of Otjivero where each inhabitant received a monthly cash grant of N9)beginning in January 2008. A research team closely monitored developments and found that within one year the rates of poverty, child malnutrition and school drop-outs had fallen significantly. Economic activities increased, school results and residents’ health status improved while the crime rate and women’s economic dependency on men were reduced. Despite these results, the Namibian government did not implement the BIG and the coalition failed to ignite a mass campaign. The country’s largest trade union federation did not play an active role and its leadership withdrew from the coalition despite support for the BIG among union members. The introduction of a BIG in Namibia will depend on the ability to the BIG coalition to create pressure ‘from below’. Trade unions and youth organisations in particular will have to mobilise their membership and present the demand for the BIG as a form of economic justice. In terms of financial and economic resources, Namibia could easily afford a national BIG and its introduction is a question of political will
Consistency and Linearity in Quantum Theory
Quantum theory is formulated as the uniquely consistent way to manipulate
probability amplitudes. The crucial ingredient is a consistency constraint: if
the amplitude of a quantum process can be computed in two different ways, the
two answers must agree. The constraint is expressed in the form of functional
equations the solution of which leads to the usual sum and product rules for
amplitudes. An immediate consequence is that the Schrodinger equation must be
linear: non-linear variants of quantum mechanics violate the requirement of
consistency.

Consistency, Amplitudes and Probabilities in Quantum Theory
Quantum theory is formulated as the only consistent way to manipulate
probability amplitudes. The crucial ingredient is a consistency constraint: if
there are two different ways to compute an amplitude the two answers must
agree. This constraint is expressed in the form of functional equations the
solution of which leads to the usual sum and product rules for amplitudes. A
consequence is that the Schrodinger equation must be linear: non-linear
variants of quantum mechanics are inconsistent. The physical interpretation of
the theory is given in terms of a single natural rule. This rule, which does
not itself involve probabilities, is used to obtain a proof of Born's
statistical postulate. Thus, consistency leads to indeterminism.

The limits of transnational solidarity: the Congress of South African Trade Unions and the Swaziland and Zimbabwean crises
The Congress of South African Trade Unions (COSATU), the main union federation in South Africa, was instrumental in ending apartheid. This paper evaluates COSATU's post-apartheid role in working for democracy elsewhere in Southern Africa through deepening transnational solidarity, focusing on its role in Zimbabwe and Swaziland. Although the federation successfully mobilised trade union members to oppose the contravention of human and labor rights, its ability to affect lasting change was limited by contradictory messages and actions by the South African government, the dualistic nature of institutional formation in these countries, strategic miscalculations and structural limitations on union power
Towards Democratic Development States in Southern Africa
The dawn of the twenty-first century heralded an apparent change of fortunes for most sub-Saharan African economies, with annual growth averaging over 5% for fifteen years. However, this was not accompanied by structural transformation: poverty, food insecurity, unemployment and inequality persist. Structural transformation has not been - and indeed cannot be - delivered by market forces and neo-liberal economic policies; it requires a state committed to development, and to achieving it in a democratic way. To what extent do the countries of Southern Africa exhibit the characteristics of such a 'developmental state'? What steps, if any, do they need to take in order to become one? The book answers the questions with respect to South Africa, Botswana, Namibia, Zimbabwe, Angola and Malawi. Godfrey Kanyenze and his colleagues have assembled a distinguished team of writers to take the temperature of the regional political economy, and chart a path for its future development
Crystal structures of the Mnk2 kinase domain reveal an inhibitory conformation and a zinc binding site
Human mitogen-activated protein kinases (MAPK)-interacting kinases 1 and 2 (Mnk1 and Mnk2) target the translational machinery by phosphorylation of the eukaryotic initiation factor 4E (eIF4E). Here, we present the 2.1 Å crystal structure of a nonphosphorylated Mnk2 fragment that encompasses the kinase domain. The results show Mnk-specific features such as a zinc binding motif and an atypical open conformation of the activation segment. In addition, the ATP binding pocket contains an Asp -Phe-Asp (DFD) in place of the canonical magnesium binding Asp-Phe-Gly (DFG) motif. The phenylalanine of this motif sticks into the ATP binding pocket and blocks ATP binding as observed with inhibitor bound and, thus, inactive p38 kinase. Replacement of the DFD by the canonical DFG motif affects the conformation of Mnk2, but not ATP binding and kinase activity. The results suggest that the ATP binding pocket and the activation segment of Mnk2 require conformational switches to provide kinase activity. © 2005 Elsevier Ltd.

The Contribution of Campbell v. Zimbabwe to the Foreign Investment Law on Expropriations
Since 2000, the Zimbabwean government has expropriated a string of white-owned commercial lands. In March 2008, in a consolidated case (Mike Campbell (Pvt) Ltd and Others v. Zimbabwe), 79 applicants filed an application with the Southern African Development Community Tribunal (SADC Tribunal) to challenge the legality of the acquisition of certain agricultural lands by the Zimbabwean government. On 28 November 2008, the Tribunal ruled that the expropriations of agricultural lands by the Zimbabwean government were illegal because they were based on racial discrimination and did not compensate the applicants. This paper seeks to understand the contribution that the Campbell case brings to the law on foreign direct investment, especially the principle that expropriations must not be discriminatory. Investment law generally prohibits discriminatory expropriations or nationalizations on the basis of race, with the notable exception of post-colonial expropriations carried out to end the economic domination of the nationals of the former colonial power. By declaring that the expropriations of white-owned agricultural lands in Zimbabwe were illegal because they amounted to racial discrimination, the SADC Tribunal in Campbell appears to develop the investment law jurisprudence on expropriations by creating an exception to the exception. Accordingly, the question that this paper addresses centers on the extent to which a country can expropriate property as part of a general government program to correct present economic inequalities brought about by a colonial past. After an exposition of the applicable laws and an explanation of the contribution of Campbell, the paper discusses whether the SADC Tribunal rightly decided the Campbell case and, if not, how the case could and should have been decided
