‘TE NYƆGEYƐNG GBENGBENG!’ (‘WE ARE HOLDING THE UMBRELLA VERY TIGHT!’): EXPLAINING THE POPULARITY OF THE NDC IN THE UPPER WEST REGION OF GHANA
Authors: Bob-Milliar George M. 
Published: July 2011

ABSTRACTThis article analyses the reasons why, since the beginning of the Fourth Republic in 1992, the Upper West Region (UWR) has become one of the strongholds of the National Democratic Congress (NDC) in northern Ghana. In all five general elections to date, the NDC has won more than half of the presidential vote and over 70 per cent of the parliamentary seats. The article explores the factors that explain the NDC's electoral dominance in the UWR. At the regional level the accepted argument has been that the NDC's predecessor extended developments to the area. However, if voting preferences are based on development considerations, why didn't loyalty shift to the NPP? I argue that political loyalty is generational and that the popularity of the NDC in the UWR can be understood through an appreciation of the recent history of the region. On 14 January 1983, PNDC Law 41 decreed the creation of the Upper West Region, carved out of what was then the Upper Region. I conclude that the political and socio-economic opportunities that came along with decentralization are historical memories of high value, which the NDC capitalizes on in its electioneering campaigns.
PEACEFUL MEMORIES: REMEMBERING AND FORGETTING POLITICAL VIOLENCE IN KANGWANE, SOUTH AFRICA
Authors: Ally Shireen 
Published: July 2011

ABSTRACTDespite its manifest, if largely undocumented, histories of menacing violence and perilous politics, the thrust of popular memory in the former apartheid bantustan of KaNgwane insists that it was a peaceful, even apolitical, place. In a contemporary South African memorial culture that idealizes memories of victimization by (and resistance to) apartheid and its political violence, why would some in KaNgwane persistently narrate the past through tropes of peaceful order and disavowals of the political? Are these mnemonic effacements in KaNgwane best conceived of as forms of forgetting? This article challenges such a proposition. First, it recovers the hitherto unrecognized politics and violence in KaNgwane, in part (and paradoxically) out of the very same narratives that deny such histories. Second, it explores the dialectical co-implication of remembering and forgetting, and of memory and history, in KaNgwane's supposed anamnesis. And third, it proposes that the occlusions and assurances of memory in KaNgwane are structured by a localized semiotics in which politics is retrospectively signified by order and restraint, and negated by disorder and revolt. In this ‘memory work’, KaNgwane's past is anaesthetized of violence, and heroism is recovered not from rehearsals of victimization and resistance, but from memories of pacified civility instead.
Identification and biochemical characterization of two novel peroxiredoxins in a liver fluke,Clonorchis sinensis

SUMMARYWe identified 2 novel genes encoding different 2-Cys peroxiredoxins (PRxs), designated CsPRx2 and CsPRx3, inClonorchis sinensis, which invades the human hepatobiliary tracts. TheCsPRx2gene expression was temporally increased along with the parasite's development and its protein product was detected in almost all parts of adult worms including subtegument, as well as excretory-secretory products. Conversely,CsPRx3expression was temporally maintained at a basal level and largely restricted within interior parts of various tissues/organs. The recombinant forms of CsPRx proteins exhibited reducing activity against various hydroperoxides in the presence of either thioredoxin or glutathione (GSH) as a reducing equivalent, although they preferred H2O2and GSH as a catalytic substrate and electron donor, respectively. A steady-state kinetic study demonstrated that the CsPRx proteins followed a saturable, Michaelis-Menten-type equation with the catalytic efficiencies (kcat/Km) ranging from 103to 104M−1s−1, somewhat lower than those for other PRxs studied (104–105M−1s−1). The expression patterns and histological distributions specific to CsPRx2 and CsPRx3 might suggest different physiological functions of the antioxidant enzymes in protecting the worms against oxidative damage.
The Prudent Dissident: Unheroic Resistance in Sophocles'Antigone
Authors: Kirkpatrick Jennet 
Published: July 2011

AbstractMost contemporary political theorists who have interpreted Sophocles'Antigonehave focused on the fearsome clash between Antigone and Creon. The relationship between Antigone and her weaker, more cautious sister Ismene has not garnered similar attention. This essay addresses this gap by revisiting the tantalizing possibility that Ismene played a more significant role in resisting Creon than has often been assumed. The essay shifts the analysis ofAntigone, first, by illuminating the complex and fraught relationship between two women and emphasizing the political and legal challenges that they face together as women. Second, the essay shifts focus from vertical power relations—that is, between the individual and government—to horizontal power relations between disempowered outsiders. On this reading,Antigonereveals less about the downfall of a character than it does about the political power of the weak and disadvantaged.
Kant on the Role of the Retributive Outlook in Moral and Political Life
Authors: Shuster Arthur 
Published: July 2011

AbstractKant is regarded as one of the staunchest advocates of retributive punishment in the modern tradition. This essay makes the case that a careful reexamination of Kant's account of punishment is necessary, especially in light of liberalism's characteristic inability to give the powerful moral appeal of retribution its due. Kant attempted to provide a clear analysis of what we mean when we say that morality demands that punishment be “proportional” to the crime. According to Kant, punishment's retributive aspect—as distinguished from its deterrent or restorative effects—is primarily concerned with redeeming (negative) moral worth. This paper attempts to unpack this claim by examining Kant's discussions of judicial punishment, the conscience, and divine punishment, respectively. It concludes that as a result of serious unresolved difficulties in his arguments for retribution, Kant manages only to deepen the question of the morality of retribution rather than to give it a decisive answer.

Published: July 2011

Cowpea, an indigenous crop to sub-Saharan Africa, is found mainly in the dry savanna regions along with cereals such as millets and sorghum. Cowpea is grown primarily for human consumption of the grains, which are rich in protein, carbohydrates and contain some minerals. The development and deployment of cowpea varieties with higher nutritional value will be of immense benefit to consumers. As a first step in the enhancement of mineral content in cowpea grains, several germplasm lines (1541) of different origins and obtained from the genetic resources unit at IITA were sown in the experimental field in Minjibir, Kano State, Nigeria. The grains were analysed for protein and nine mineral contents. However, in this study, we shall report data on crude protein, Fe, Zn, Ca, Mg, K and P. The data generated from the chemical analysis were subjected to the ‘mixture of normal distributions’ clustering method, which distributed the cowpea lines into nine groups. Groups G7 and G9 contained 174 genotypes and these were characterized by high mineral concentrations. The mean nutritional content values for group G9 were 24.7% for protein, and 58.9, 41.5, 1107, 2132, 15,282 and 5664 mg/kg for Fe, Zn, Ca, Mg, K and P, respectively. On the other hand, the 363 lines making up groups G2, G3 and G6 showed low amounts of nutrients in their grains. Some of the lines in G7 and G9 would be good as parents to use in breeding programmes that aimed at developing nutrient-dense cowpea varieties.
Soil fertility and the yield response to the System of Rice Intensification
Authors: Turmel Marie-Soleil , Turner Benjamin L. , Whalen Joann K. 
Published: July 2011

AbstractThe System of Rice Intensification (SRI) is a low-input rice (Oryza sativa L.) production system that differs from conventional systems in several ways: seedlings are transplanted earlier and are more widely spaced, organic fertilizer is often used in addition to mineral fertilizer, and soils are irrigated intermittently rather than flooded for long periods. The yield benefits of SRI compared to conventional systems can be substantial, and yet are regionally variable and have been the subject of considerable debate, due partly to a lack of mechanistic understanding. Here we show that soil properties may in part explain the variability in yield response to SRI. A meta-analysis of data from 72 field studies where SRI was compared with conventional systems indicates that yields increased significantly (P<0.0001) when SRI was implemented on highly weathered infertile soils rich in iron and aluminum oxides (Acrisols and Ferralsols), but there was no difference in yield between SRI and conventional systems in more fertile favorable soils for rice production (Gleysols, Luvisols and Fluvisols). The yield difference between SRI and conventional rice production therefore appears to be related in part to soil properties linked to weathering. This should help resolve the debate about the value of SRI and allow research to be targeted toward understanding the biological and chemical processes in soils under SRI management.
A capacity assessment of New England's large animal slaughter facilities as relative to meat production for the regional food system
Authors: Lewis Chelsea Bardot , Peters Christian J. 
Published: July 2011

AbstractDemand for locally and regionally produced meat has stimulated increased interest in livestock production among New England farmers. The region's livestock producers lament lack of access to slaughter and processing infrastructure. However, there is very little research on New England's slaughter industry to document this perceived problem. For this reason, we tested the hypothesis that a shortage of slaughter and processing infrastructure constrains the production of livestock for meat in New England. The region's large animal slaughter facility owners and managers were surveyed to determine current slaughter and processing capacity and identify challenges facilities face in meeting increased producer demand. The estimates of current capacity were then compared to USDA data on livestock slaughter and large animal marketings. The region's existing abattoirs could slaughter 63–84% of all animals marketed, but could process only 29–43%. New England's infrastructure for slaughter operated at only 38% of total physical capacity in 2009, while on-site processing infrastructure operated at 66% of total physical capacity (78% if only on-site inspected capacity is considered). Moreover, surveys with facility operators showed that the primary constraints faced by existing slaughterhouses are a shortage of skilled labor and the seasonality of the livestock industry, with periods of very high demand for slaughter in the fall and very low demand in the spring and early summer. Additional infrastructure, particularly for processing, would be needed were regional livestock production to increase. However, simply increasing physical capacity will not address the issues of labor availability and demand seasonality expressed by slaughter facility owners.
Study Of Phenothiazine On p53 Core Domain Mutant Y220C: Finding The Anti-tumor Activity Of Phenothiazine

Published: July 2011

AbstractThe tumor suppressor protein p53 is a transcription factor that plays a key role in the prevention of cancer development. The p53 cancer mutation Y220C induces formation of a cavity on the protein's surface that can accommodate stabilizing small molecules. We have attempted with the help of virtual screening and molecular docking approach using Lamarckian Genetic Algorithm to elucidate the extent of specificity of p53 cancer mutation Y220C towards different class of Phenothiazines (an anti-cancer agent).The 393 residue p53 tumor suppressor protein exists in a dynamic equilibrium to form homotetramers. Each chain comprises several functional domains. The N terminal part of the protein consists of the trans-activation domain (residues 1–63) followed by a proline rich region (64– 92). The central (core) domain (p53 core domain) is responsible for binding. The C terminal part of p53 contains the tetramerization domain (residues 326–355) and the negative regulatory domain at the extreme C terminus (363–393), which contains phosphorylation and acetylation sites and regulates the DNA binding activity of p53.The docking result of the study of 2,000 Phenothiazines demonstrated that the binding energies were in the range of -10.54 kcal/mol to -1.14 kcal/mol, with 8 molecules showing hydrogen bonds with the active site residues (Lys 164). All the selected 2000 inhibitors were selected on the basis of the structural specificity to the enzyme towards its substrate and inhibitors. Our research provides a blueprint for the design of more potent and specific drugs that rescue p53-Y220C.

In this paper insights into the behaviour of resistive wall modes (RWMs) in the RFX-mod reversed field pinch device are given, with a focus on 3D issues in the characterization of the m spectrum of the mode and on the study of multi-harmonic coupling.
In the first part of the paper the interaction between multiple unstable RWMs is studied and the presence of a coupling between different poloidal components of the most unstable RWM is demonstrated, taking advantage of the flexibility of the RFX-mod control system.
In the second part of the work, the dependence of the growth rates of RWMs on a complete set of plasma parameters is studied in order to create a complete and homogeneous database, which permits a careful validation of stability codes.
Finally, the experimental data are compared with the code predictions which take into account the 3D structure of conductors around the plasma. The different effects that modify the simple description, where unstable modes can be identified with single Fourier harmonics, appear to be explained by a mixture of toroidicity-induced and 3D eddy current effects.

Abstract
Fe-doped TiO
2 catalyst was prepared by the hydrothermal method. The resulting nanopowders were characterized by x-ray diffraction, transmission electron microscopy and Raman and UV-visible spectroscopies. The photocatalytic activity of the Fe-doped TiO
2 was tested by decomposition of methylene orange with a concentration of 10 mg
l
−1 in aqueous solution. The obtained results showed that methylene orange was significantly degraded after irradiation for 90 min under a halogen lamp and sunlight. The doping effect on the photocatalytic activity of the iron-doped catalyst samples are discussed.
Milk Marketing Order Winners and Losers
Authors: Chouinard Hayley H. , Davis David E. , LaFrance Jeffrey T. , Perloff Jeffrey M. 
Published: July 2011

AbstractDetermining the impacts on consumers of governmental policies that affect the demand for food products requires a theoretically consistent micro‐level demand model. We estimate a system of demands for weekly city‐level dairy product purchases by nonlinear three‐stage least squares to account for joint determination between quantities and prices. We analyze the distributional effects of federal milk marketing orders, and find results that vary substantially across demographic groups. Families with young children suffer, while wealthier, childless couples benefit. We also find that households with lower incomes bear a greater regulatory burden due to marketing orders than those with higher income levels.
The Adequacy of Speculation in Agricultural Futures Markets: Too Much of a Good Thing?
Authors: Sanders Dwight R. , Irwin Scott H. , Merrin Robert P. 
Published: July 2011

AbstractThis paper revisits the “adequacy of speculation” debate in agricultural futures markets using the positions held by index funds in the Commitment of Traders reports. Index fund positions were a relatively stable percentage of total open interest from 2006–2008. Traditional speculative measures do not show any material shifts over the sample period. Even after adjusting speculative indices for commodity index fund positions, values are within the historical ranges reported in prior research. One implication is that long‐only index funds may be beneficial in markets traditionally dominated by short hedging.
The Social Costs and Benefits of Biofuels: The Intersection of Environmental, Energy and Agricultural Policy
Authors: de Gorter Harry , Just David R. 
Published: July 2011

AbstractThe efficacy of alternative biofuel policies in achieving energy, environmental and agricultural policy goals is assessed using economic cost‐benefit analysis. Government mandates are superior to consumption subsidies, especially with suboptimal fuel taxes and the higher costs involved with raising tax revenues. But subsidies with mandates cause adverse interaction effects; oil consumption is subsidized instead. This unique result also applies to renewable electricity that faces similar policy combinations. Ethanol policy can have a significant impact on corn prices; if not, inefficiency costs rise sharply. Ethanol policy can increase the inefficiency of farm subsidies and vice‐versa. Policies that discriminate against trade, such as production subsidies and tariffs, can more than offset any benefits of a mandate. Sustainability standards are ineffective and illegal according to the WTO, and so should be re‐designed.
The Political Economy of Agricultural and Food Policies: Recent Contributions, New Insights, and Areas for Further Research
Authors: Swinnen Johan F.M. 
Published: July 2011

AbstractThis article reviews innovative research that has emerged in recent years, both in the general economics literature and as applied to agricultural and food policies. There have been important innovations and new insights in these fields, particularly regarding the micro‐foundations of political decision‐making, the impact of political institutions and ideology, and the role of the media. Data have also improved substantially. However, there are still important gaps in our understanding. Further research should focus on capturing interactions between explanatory variables, more refined measurement of (political) institutions and reforms, the effects of international agreements, broader representation of agents, more explicit modeling of crises, discontinuous effects, and the interaction of multiple policies.
Estimating classification probabilities in high-dimensional diagnostic studies
Authors: Appel Inka J. , Gronwald Wolfram , Spang Rainer 
Published: July 2011

Abstract
Motivation: Classification algorithms for high-dimensional biological data like gene expression profiles or metabolomic fingerprints are typically evaluated by the number of misclassifications across a test dataset. However, to judge the classification of a single case in the context of clinical diagnosis, we need to assess the uncertainties associated with that individual case rather than the average accuracy across many cases. Reliability of individual classifications can be expressed in terms of class probabilities. While classification algorithms are a well-developed area of research, the estimation of class probabilities is considerably less progressed in biology, with only a few classification algorithms that provide estimated class probabilities.
Results: We compared several probability estimators in the context of classification of metabolomics profiles. Evaluation criteria included sparseness biases, calibration of the estimator, the variance of the estimator and its performance in identifying highly reliable classifications. We observed that several of them display artifacts that compromise their use in practice. Classification probabilities based on a combination of local cross-validation error rates and monotone regression prove superior in metabolomic profiling.

Metoclopramide Versus Ondansetron for the Treatment of Vomiting in Children With Acute Gastroenteritis
Authors: Al‐Ansari Khalid , Alomary Salim , Abdulateef Hala , Alshawagfa Mohammed , Kamal Khalid 
Published: July 2011

ABSTRACTObjective:To compare the efficacy and safety of ondansetron versus less expensive metoclopramide in the treatment of children with persistent vomiting with acute gastroenteritis.Materials and Methods:A double‐blind trial including consecutive consented patients ages 1 to 14 years was conducted in an urban infirmary setting from June 2008 through December 2008. Children were randomized to receive a single dose of intravenous ondansetron or metoclopramide. The primary efficacy outcome was the proportion of patients with cessation of vomiting shortly after completion of the study medication infusion in each group. Observed adverse effects and diarrhea frequency during admission and in follow‐up were recorded to assess safety.Results:One hundred sixty‐seven previously healthy children (median age 3 years) diagnosed as having acute gastroenteritis with persistent vomiting completed treatment and observation. Cessation of vomiting was achieved in 68/84 patients (81%) of the ondansetron and 60/83 (72%) of the metoclopramide groups, P = 0.14. Mean time to complete cessation of vomiting was 39 minutes (SD 111) for ondansetron, and 61 minutes (SD 110) for metoclopramide, P = 0.2. The mean length of infirmary stay was 550 minutes (SD 427) for ondansetron and 575 minutes (SD 449) for metoclopramide, P = 0.71. Revisit rate, readmissions rate, and frequency of diarrhea after discharge were similar in the 2 treatment groups. No adverse reaction or other safety concerns were identified.Conclusions:In the sample size tested, intravenous metoclopramide therapy did not differ from ondansetron in the treatment of persistent vomiting for children with gastroenteritis admitted for intravenous fluid hydration.
