The media tends to influence public perceptions of the criminal justice system. The media’s impact, known as the CSI Effect, is not well documented in criminal justice majors. The present study adds to a small body of literature regarding the impact of media on criminal justice students’ decisions, and seeks to identify the factors that influence students’ choices, regarding their major/career goals. Based on the results from surveys administered at an urban university in the United States, most criminal justice students reported that they were not influenced by the media, yet the vast majority believed this to be true of their fellow majors. These students chose criminal justice because they found the subject matter interesting and relevant to the real world, and they wanted to work in a field in which they could be a problem solver. Upon graduation, these students overwhelmingly reported an interest in pursuing a career in federal law enforcement. Unfortunately, corrections, a field dedicated to working with offenders, was the lowest preferred profession among criminal justice students.

It has been argued that the rise in popularity of crime show dramas over the past few years has led to jurors holding unrealistic expectations regarding the type of evidence presented at trial. This has been coined the CSI effect. We investigated the CSI effect and the less well-known Tech effect-assigning more weight to evidence if obtained through technological means-and the impact of crime severity on juror decision-making. However, we argue that as time progresses, such effects will no longer be found to impact juror decision-making processes. We propose that past effects reported in the literature can be explained by considering a novelty bias. Using both frequentist and Bayesian frameworks, we tested this claim. Participants were primed with a newspaper that either contained a forensic, technology, or neutral article. They were then presented with two crime scenarios and asked to provide a verdict and a confidence rating. We find that mock jurors were unaffected by either the priming manipulation or crime severity, finding no evidence for either the CSI or Tech effects. The data suggest jurors are not as easily biased as has been previously argued in the literature, indicating a potential shift in public perceptions and expectations regarding evidence.

The present paper analyses the aspects of investigations of crime involving cryptocurrencies as a payment instrument. Ever since their emergence, cryptocurrencies have come to be actively used by criminals in all types of illegal activities, such as drug trafficking, money laundering, illegal arms trade, payments for criminal services and many other crimes. The paper aims to establish the methods of crime investigation to track data on cryptocurrency transactions and identify and show up the participants of illegal operations. The author shows that the development of computer and digital information technologies and the Internet has brought about the ever-increasing prevalence of cryptocurrencies in all social domains, including the shadow sector, i. e., the criminal world. Figures are provided illustrating the overall circulation of cryptocurrencies in the world and its illegal segment. Explaining the attractiveness of cryptocurrencies for criminal structures, the author points at its anonymity and inadequate regulation of various aspects in laws. An analysis is provided of the practice of countries where cryptocurrency circulation is not only permitted but regulated to a maximum possible extent. The impact of such regulation for the state of the shadow cryptocurrency market is shown. The research further concerns the potential for bringing international expertise to the Socialist Republic of Vietnam. Potential methods of crime investigation concerning shadow cryptocurrency transactions are outlined, helping to identify and show up the participants involved. Forecasts are provided as to the development of modern forensics and the emergence of new forensic methods helping to uncover cryptocurrency-related crime; proposals are drawn for amending criminal and criminal procedure laws to facilitate investigations in the new context.

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.

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.

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.
