Energy overview of Botswana: generation and consumption

Botswana has a basic need to explore its energy concept, this being its energy sources, generation and percentage of the population with access to electricity. At present, Botswana generates electricity from coal, which supplies about 29% (on average) of the country’s demand. The other 71% is imported mainly from South Africa (Eskom). Consequently, the dependence of Botswana on imports posses threats to the security of its energy supply. As a result, there is the need to understand the bases for a possible generation expansion that would substantiate existing documentation. In view of this need, this study investigates the existing energy sources as well as energy consumption and production levels in Botswana. The study would be further developed by making projections of the energy demand up until the year 2020. The key techniques that were used include; literature review, questionnaire survey and an empirical study. The results presented indicated that, current dependable operation capacity (i.e. 100MW) should be increased to 2,595 MW or more assuming 85% plant efficiency. This would then be able to meet the growing demand for energy use. In addition, the installed capacity would be able to support commercial and mining activities for the growth of the economy.

Phylogenies reveal predictive power of traditional medicine in bioprospecting

There is controversy about whether traditional medicine can guide drug discovery, and investment in ethnobotanically led research has fluctuated. One view is that traditionally used plants are not necessarily efficacious and there are no robust methods for distinguishing the ones that are most likely to be bioactive when selecting species for further testing. Here, we reconstruct a genus-level molecular phylogeny representing the 20,000 species found in the floras of three disparate biodiversity hotspots: Nepal, New Zealand and the Cape of South Africa. Borrowing phylogenetic methods from community ecology, we reveal significant clustering of the 1,500 traditionally used species, and provide a direct measure of the relatedness of the three medicinal floras. We demonstrate shared phylogenetic patterns across the floras: related plants from these regions are used to treat medical conditions in the same therapeutic areas. This strongly suggests independent discovery of plant efficacy, an interpretation corroborated by the presence of a significantly greater proportion of known bioactive species in these plant groups than in a random sample. Phylogenetic cross-cultural comparison can focus screening efforts on a subset of traditionally used plants that are richer in bioactive compounds, and could revitalise the use of traditional knowledge in bioprospecting.

Legal outlier, again? U.S. felon suffrage: comparative and international human rights perspectives

The judiciousness of American felon suffrage policies has long been the subject of scholarly debate, not least due to the large number of affected Americans: an estimated 5.3 million citizens are ineligible to vote as a result of a criminal conviction. This article offers comparative law and international human rights perspectives and aims to make two main contributions to the American and global discourse. After an introduction in Part I, Part II offers comparative law perspectives on challenges to disenfranchisement legislation, juxtaposing U.S. case law against recent judgments rendered by courts in Canada, South Africa, Australia, and by the European Court of Human Rights. The article submits that owing to its unique constitutional stipulations, as well as to a general reluctance to engage foreign legal sources, U.S. jurisprudence lags behind an emerging global jurisprudential trend that increasingly views convicts’ disenfranchisement as a suspect practice and subjects it to judicial review. This transnational judicial discourse follows a democratic paradigm and adopts a “residual liberty” approach to criminal justice that considers convicts to be rights-holders. The discourse rejects regulatory justifications for convicts’ disenfranchisement, and instead sees disenfranchisement as a penal measure. In order to determine its suitability as a punishment, the adverse effects of disenfranchisement are weighed against its purported social benefits, using balancing or proportionality review. Part III analyzes the international human rights treaty regime. It assesses, in particular, Article 25 of the International Covenant on Civil and Political Rights (“ICCPR”), which proclaims that “every citizen” has a right to vote without “unreasonable restrictions.” The analysis concludes that the phrase “unreasonable restrictions” is generally interpreted in a manner which tolerates certain forms of disenfranchisement, whereas other forms (such as life disenfranchisement) may be incompatible with treaty obligations. This article submits that disenfranchisement is a normatively flawed punishment. It fails to treat convicts as politically-equal community members, degrades them, and causes them grave harms both as individuals and as members of social groups. These adverse effects outweigh the purported social benefits of disenfranchisement. Furthermore, as a core component of the right to vote, voter eligibility should cease to be subjected to balancing or proportionality review. The presumed facilitative nature of the right to vote makes suffrage less susceptible to deference-based objections regarding the judicial review of legislation, as well as to cultural relativity objections to further the international standardization of human rights obligations. In view of this, this article proposes the adoption of a new optional protocol to the ICCPR proscribing convicts’ disenfranchisement. The article draws analogies between the proposed protocol and the ICCPR’s “Optional Protocol Aiming at the Abolition of the Death Penalty.” If adopted, the proposed protocol would strengthen the current trajectory towards expanding convicts’ suffrage that emanates from the invigorated transnational judicial discourse.

Responsible tourism and sustainability: the case of Kumarakom in Kerala, India

This paper discusses the notion of ‘responsible tourism’ and its current use within the tourism literature. We argue that the concept as used currently means everything and therefore adds nothing to the conceptual terrain of tourism trends and nomenclatures. We then introduce our own understanding of the concept arguing that while responsible tourism is linked to sustainability initiatives such as alternative tourism, ecotourism, ethical tourism, green tourism, soft tourism, pro-poor tourism, geo-tourism, integrated tourism, community-based tourism, etc it also demarcates an analytical realm of its own. We suggest that the practical use of the term in areas where it has been adopted (such as South Africa and Kerala for instance) suggests a rather restricted use. We identified this realm as the tourism sector-specific manifestation of the corporate social responsibility (CSR) agenda. Following Flyvberg's [(2006). Five misunderstandings about case-study research. Qualitative Inquiry, 12(2), 219–245] call for exemplars and paradigmatic case studies to advance knowledge in a particular domain, the responsible tourism initiative in Kumarakon, Kerala, is presented. Discussion of the case study traces the particular governance context of Kerala and the position of tourism in the state economy. The responsible tourism initiatives at the state level and local level are then described highlighting the ‘how’ of the implementation and the impact that it has produced. Generic, non-prescriptive principles that could be said to be necessary in some form for the successful translation of responsible tourism principles to practices are then identified. Such an approach is contrasted with one that places faith in the voluntary adoption of ‘responsible’ practices by the private sector on its own. It is argued that responsible tourism can make a contribution to practice provided the conceptual terrain is delineated against other forms of tourism and if research within the terrain can unpack the particular forms of challenges that are thrown up by the delineation itself.

Apartment ownership: the English version needs reforming

In this contribution, the English commonhold system, which enables the development of freehold units in a multi-unit development, is critically re-visited. Provision is made for the development of freehold apartments on land with a registered commonhold title. At the date of registration, a management body for the scheme, the commonhold association, must be in place. Each purchaser of a unit in the relevant building obtains freehold property on purchase. The property and management of the building housing the units and of the common areas of the scheme are, by contrast, withheld from unit holders and vested in the commonhold association, which is a special kind of body corporate. Since the coming into force of the English legislation, a set of defects have been detected. This contribution re-assesses the main problem areas and makes a number of reform suggestions drawing on material from a number of jurisdictions, notably South Africa, France and Germany. Avoidable problems are likely to arise with any conversions to commonhold from the predominant English long lease system, owing to the narrowness of the conversion rules. The manner in which ownership of units and the common parts are regulated, a key aspect in any such system, merits re-assessment. It seems that here the English rules survive comparison. The rules pertaining to constitution of the commonhold association fail to provide sufficient safeguards for unpaid scheme creditors. The rules relating leasing of commonhold units seem inadequately thought out. There is a conspicuous absence of real remedies for non-payment of assessments by unit holders. The effect of these and other aspects may help to explain why commonhold has had a limited numerical impact. The time for a second generation reforming statute may have come.

A police state? The Nyasaland emergency and colonial intelligence.

The Nyasaland Emergency in 1959 proved a decisive turning point in the history of the Federation of Rhodesia and Nyasaland, which from 1953 to 1963 brought together the territories of Northern Rhodesia (Zambia), Southern Rhodesia (Zambia) and Nyasaland (Malawi) under a settler-dominated federal government. The British and Nyasaland governments defended the emergency by claiming to have gathered intelligence which showed that the Nyasaland African Congress was preparing a campaign of sabotage and murder. The Devlin Commission, appointed to investigate the emergency, dismissed the evidence of a ‘murder plot’, criticised the Nyasaland government's handling of the Emergency and, notoriously, described Nyasaland as a ‘police state’. This article has two principal aims. First, using the recently declassified papers of the Intelligence and Security Department (ISD) of the Colonial Office, it seeks to provide the first detailed account of what the British government knew of the intelligence relating to the ‘murder plot’ and how they assessed it, prior to the outbreak of the emergency. It demonstrates that officials in the ISD and members of the Security Service adopted a far more cautious attitude towards the intelligence than did Conservative ministers, and had greater qualms about allowing it into the public domain to justify government policy. Second, the article examines the implications of Devlin's use of the phrase ‘police state’ for Nyasaland and for the late colonial state in general. It contrasts Devlin's use of the term with that of security experts in the ISD, who routinely applied it to policing systems that diverged from their own preferred model. Hence, whereas Devlin compared policing in Nyasaland unfavourably with that in Southern Rhodesia, implying, ironically, that Nyasaland was ‘under-policed’ (because there were fewer police per head of population in Nyasaland than in Southern Rhodesia), the ISD regarded the intensive system of policing operated by the British South Africa Police in Southern Rhodesia as characteristic of a ‘police state’. The article suggests that the frequent use of the term ‘police state’ was indicative of broader anxieties about what Britain's legacy would be for the post-independence African state.

Britain and the Commonwealth: confronting the past - imagining the future

This is an extended version of Philip Murphy's inaugural lecture as director of the Institute of Commonwealth Studies, delivered on 23 February 2011. It traces the relationship of the UK with the wider Commonwealth over 40 years, paying particular attention to the rhetoric of governments and opposition parties from Wilson and Heath to Cameron. It examines the reasons for the Commonwealth being relegated to a peripheral role in British foreign policy, especially European preoccupations and the issues of Rhodesia and South Africa. It argues that the Commonwealth remains of considerable practical and enormous symbolic importance to the UK. The British government should engage with the Commonwealth more than it has done in the recent past and the Commonwealth should be both open to and critical of its imperial past.

The Jua Kali and the Mali-Mali: the informal/formal nexus amongst Kenyan micro enterprises

This paper presents a preliminary exploration of the informal/formal economy nexus and entrepreneurial processes amongst a sample of Kenyan roadside vendors who mostly operate in the informal economy. Using semi-structured interviews, data was collected from sixty street vendors across Kenya. In particular the paper focuses on the relationship between the informal and formal economy and the factors that promote formality amongst micro and small enterprises in developing countries. The paper presents a conceptualization of a potential segmentation of the informal economy, considering the implications of this in terms of base of the pyramid initiatives and the promotion of development through enterprise.

Globalization and technology-mediated distance education: developing countries’ perspective

The contemporary global economy places great value on highly educated workers but devalues workers in repetitive or low skill jobs. In order to thrive in this new economy, countries must ensure sufficient higher education opportunities for their population. However, a lack of resources is a major barrier faced by many developing countries in expanding their higher education systems. Technology-mediated distance education has the potential to be an invaluable tool in offering educational opportunities to people, if the other necessary conditions for participation are met. Although technology-mediated education was first considered to be a medium to bridge the learning divide across space, today it is feared that it could well become an inequality intensifier. Drawing on examples from developing countries, this paper considers factors regarding implementing technology-mediated distance education, including failure to address contextual issues and possible consequences. Challenges and policy implications are also discussed.

Connecting the complex ‘lived’ world(s) of Fairtrade

Although certified Fairtrade continues to use discourses of defetishization, its move into mainstream markets has acted to refetishize the consumer–producer relationship through the use of a standardized label, which acts as a substitute for engaged knowledges. Through Fairhills, a South African Fairtrade wine project, this paper explores the contextual complexity on the producer side of the commodity network. By incorporating the national discourse of Black Economic Empowerment into its operations, both in Fairhills and in South Africa in general, Fairtrade has adapted to this context, ensuring its relevance and credibility to stakeholders. However, in the UK, little more information than that commonly associated with Fairtrade is offered to Fairhills consumers. The particular market challenges facing Fairtrade wine in the UK make this negotiation between regulation and representation extremely pertinent. A productive way forward may be to conceptualize commodity fetishism as a continuum rather than a binary particularly when considering the difficult balance required when adding complexity to the targeted message of the existing label. This strategy for the sustainability of Fairtrade may be enhanced by utilizing the micro-level dynamism and adaptability that this paper shows is inherent, and indeed essential, to the durability and transferability of the discourse of Fairtrade.

High speed keck spectroscopy of flickering in AM Her

We present fast (72 ms) spectroscopy of AM Her obtained at an intermediate brightness state just before a rise to high state. Interesting features in the line behaviour of AM Her are noted and the variability spectrum is presented and compared to that of SS Cyg.

REVIEW: Fireballs, Flares and Flickering

We review our understanding of the prototype ``Propeller'' system AE Aqr and we examine its flaring behaviour in detail. The flares are thought to arise from collisions between high density regions in the material expelled from the system after interaction with the rapidly rotating magnetosphere of the white dwarf. We show calculations of the time-dependent emergent optical spectra from the resulting hot, expanding ball of gas and derive values for the mass, lengthscale and temperature of the material involved. We see that the fits suggest that the secondary star in this system has reduced metal abundances and that, counter-intuitively, the evolution of the fireballs is best modelled as isothermal.

Healing the wounds of war: memories of violence and the making of history in Zimbabwe's most recent past.

How does a society less than two decades after a liberation war which involved large sections of the population come to terms with the memories of violence and war — a war in which there was no clear distinction between insurgent and counter‐insurgent, liberator and oppressor and in which the majority of the casualties can be found among the rural civilian population? This was a predicament not exclusive to Zimbabwe, but one which also applies to Mozambique, South Africa and, more recently, to Rwanda. Since its independence Zimbabwe has been a prime example of successful reconciliation. Ranger has argued that spiritual healing has contributed importantly to coming to terms with the trauma of war through turning violence into history. Here it will be argued that an analysis of the intersections between memories of violence, healing, and history reveals a twofold process. Social healing is made possible by a shift from conviction and compensation to revealing without convicting. At the same time healing provides an arena for communities in which competing and contesting memories of violence are renegotiated. Through these processes sense is being made of the past; history is being made.
