Major Industry

The commoditization and manufacture of rum has been a major industry in the Caribbean since the inception of the plantation as a means of amplified production to fill consumer needs. Still houses can be analysed to reflect the major economic processes active in the wider Atlantic theater. Betty’s Hope is a perfect example of the British microcosm of production, displaying themes which become archetypal within the socio-economic model of the British Caribbean and wider Atlantic world, during the historic period. These themes, exampled by the impact of that technology in the form of industrial steam manufacture, are dramatically displayed within the documentary survey and archaeology of the still house.

The Relationship

In the present study, the interplay between self-construal, social support and psychological adaptation of first generation Indian immigrants residing in Crete (N = 114) was examined. The first aim of the study was to analyze the association of self-construal with anxiety, depression, and self-esteem as indicators of psychological adaptation. It was hypothesized that Indian immigrants would maintain a more interdependent than independent self-construal and that Indians with high interdependent self-construal would receive more social support and have less adaptation problems compared to immigrants’ with a more independent self-construal. Furthermore, the second aim was to examine the relation of social support to self-construal, and psychological adaptation. It was hypothesized that interdependent self-construal would have positive effects on psychological adaptation through social support (mediation). A moderation effect was also hypothesized, in that social support was expected to act protectively for Indians with high interdependence, regarding psychological adaptation. The results verified some of the hypotheses but there were unexpected findings as well. Interdependence was not related to any indices of psychological adaptation, while a negative relationship was found between independent self-construal and self-esteem. Although, social support was not related either to self-construal or to adaptation, it acted as mediator in the relationship between interdependent self-construal and depression. Furthermore, a moderation effect was found on the relationship between independent self-construal and self-esteem. There are certain implications of these findings, regarding the impact of cultural values in counseling and the role of social support in immigrants’ psychological adaptation.

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 Impact

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.

The Impact

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.
