The Impact

This article discusses the loss of the creole languages on São Tomé Island and the societal move from multilingualism to monolingualism in Portuguese. It argues that recognizing the ideologies attached to these languages is key in understanding the language shift, but also the processes leading toward monolingualism. This qualitative study is based on three main theories: Language as social practice, language ideology, and monoglot standardization. Data comes from ethnographic fieldwork and sociolinguistic interviews with 56 speakers from the capital of São Tomé and Príncipe. I argue that the existence of multilingualism on São Tomé Island is not valued at a societal level because of the pejorative ideologies that have been held about the creole languages since colonial times. Also, the use of the creole languages stood as a problem for the creation of a unified Santomean nation, as the different racial groups on the islands had their own creole. Results show how ideologies about the Portuguese language and its association with national unity, modernity, and European-ness favored its expansion on São Tomé Island and a move toward monolingualism.

Subject The impact of the new discovery on 'superbugs'. Significance The World Health Organisation (WHO) classifies increasing resistance against antimicrobial drugs as a global health threat. In the case of malaria, which endangers about 50% of the world's population, resistance to the most effective antimalarial drug artemisinin is advancing in South-east Asia. However, recent research offers hope against antimicrobial resistant infections. In January, scientists published a revolutionary approach -- iChip-- to discover and study formerly unknown microorganisms and their antimicrobial activity. The iChip potentially paves the road for a new era of antimicrobial drug discovery that is urgently needed. Impacts The use of artemisinin-based monotherapies rather than combination treatments will contribute to artemisinin resistance. Artemisinin monotherapy is used in Angola, Cape Verde, Colombia, Equatorial Guinea, Gambia, Sao Tome and Principe, Somalia and Swaziland. These countries are therefore in danger of emerging artemisinin-resistant malaria.

Rare Opportunity

Despite a widespread trend toward the adoption of increasingly participatory approaches to political decision making in developing countries, there is little or no evidence that these practices in fact return the benefits attributed to them. This article investigates one specific worry—that participatory decision-making processes may be vulnerable to manipulation by elites. The authors report on a field experiment, drawing on a unique nationwide experiment in democratic deliberation in São Tomé and Príncipe in which the discussion leaders were randomly assigned across meetings. The randomization procedure provides a rare opportunity to identify the impact of leaders on the outcomes of group deliberations. They find that leader effects were extremely large, in many cases accounting for over one-third of all variation in the outcomes of the national discussions. These results have important implications for the design of such deliberative practices. While the total effect of leadership cannot be assessed, it may still be possible to observe when leader influence occurs and to correct for leader effects in comparisons of outcomes across deliberations.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.

The Impact

AbstractA large amount of CO has been detected above many SL9/Jupiter impacts. This gas was never detected before the collision. So, in our opinion, CO was released from a parent compound during the collision. We identify this compound as POM (polyoxymethylene), a formaldehyde (HCHO) polymer that, when suddenly heated, reformes monomeric HCHO. At temperatures higher than 1200°K HCHO cannot exist in molecular form and the most probable result of its decomposition is the formation of CO. At lower temperatures, HCHO can react with NH3 and/or HCN to form high UV-absorbing polymeric material. In our opinion, this kind of material has also to be taken in to account to explain the complex evolution of some SL9 impacts that we observed in CCD images taken with a blue filter.

AbstractHydrogen cyanide polymers – heterogeneous solids ranging in color from yellow to orange to brown to black – may be among the organic macromolecules most readily formed within the Solar System. The non-volatile black crust of comet Halley, for example, as well as the extensive orangebrown streaks in the atmosphere of Jupiter, might consist largely of such polymers synthesized from HCN formed by photolysis of methane and ammonia, the color observed depending on the concentration of HCN involved. Laboratory studies of these ubiquitous compounds point to the presence of polyamidine structures synthesized directly from hydrogen cyanide. These would be converted by water to polypeptides which can be further hydrolyzed to α-amino acids. Black polymers and multimers with conjugated ladder structures derived from HCN could also be formed and might well be the source of the many nitrogen heterocycles, adenine included, observed after pyrolysis. The dark brown color arising from the impacts of comet P/Shoemaker-Levy 9 on Jupiter might therefore be mainly caused by the presence of HCN polymers, whether originally present, deposited by the impactor or synthesized directly from HCN. Spectroscopic detection of these predicted macromolecules and their hydrolytic and pyrolytic by-products would strengthen significantly the hypothesis that cyanide polymerization is a preferred pathway for prebiotic and extraterrestrial chemistry.

The Impact

Crushed and statically compressed Madagascar graphite that was explosively shocked at 425 kb by means of a planar flyer-plate is characterized by a black zone extending for 2 to 3 nun below the impact plane of the driver. Beyond this point, the material assumes the normal gray color of graphite. The thickness of the black zone is identical with the distance taken by the relaxation wave to overtake the compression wave.The main mechanical characteristic of the black material is its great hardness; steel scalpels and razor blades are readily blunted during attempts to cut it. An average microhardness value of 95-3 DPHN was obtained with a 10 kg load. This figure is a minimum because the indentations were usually cracked; 14.8 DPHN was measured in the gray zone.

In the mid-nineteenth century Virchow revolutionized pathology by introduction of the concept of “cellular pathology”. Today, a century later, this term has increasing significance in health and disease. We now are in the beginning of a new era in pathology, one which might well be termed “organelle pathology” or “subcellular pathology”. The impact of lysosomal diseases on clinical medicine exemplifies this role of pathology of organelles in elucidation of disease today.Another aspect of cell organelles of prime importance is their pathologic alteration by drugs, toxins, hormones and malnutrition. The sensitivity of cell organelles to minute alterations in their environment offers an accurate evaluation of the site of action of drugs in the study of both function and toxicity. Examples of mitochondrial lesions include the effect of DDD on the adrenal cortex, riboflavin deficiency on liver cells, elevated blood ammonia on the neuron and some 8-aminoquinolines on myocardium.
