The Impact

The dominant view in economics is that increasing demands for flexibility on the labour market jeopardizes employment security. However, against the prediction of a negative relationship or a`trade-off' between flexibility and security, there is evidence for a positive, mutually reinforcing relationship known as the `flexicurity' thesis. Using comparative panel data for 14 European countries, we elaborate dynamic outcome indicators for flexibility and employment security to assess the differences across countries and welfare regimes in balancing the two.We estimate transition models to explain the observed mobility patterns.The outcomes confirm the impact of the institutional set-up indicated by regime type on these transitions supporting the `variety of capitalism' approach.The regulated Southern and Continental regimes perform worst and the unregulated Anglo-Saxon and Nordic regimes best in attaining high levels of flexibility and employment security simultaneously, though for both regimes with a small loss either in flexibility or in security.

Purpose The purpose of this paper is to present corporate wellness (CW) as an approach to worker well-being and as distinct from workplace health promotion (WHP). Theoretical explanations of the contribution of CW and WHP to the economic and social legitimacy objectives of human resource management (HRM) serve to elucidate this distinction and also to highlight the problematic nature of CW. An alternative approach to worker well-being, firm performance and social legitimacy of the firm is discussed. Design/methodology/approach This is a review paper that analyses research into CW as a discrete approach to the management of people and compares this body of knowledge with ancillary studies of the impact of policies more commonly aligned with HRM in order to achieve the purpose of the paper. Findings The review is critical of CW as a means of achieving competitive advantage through people due to the probability of dysfunctional outcomes, namely exacerbating the health and well-being of the workforce, especially the mental health of workers. Practical implications Due to the sizeable investment in CW programmes, the paper advocates a focus on equity in pay, employment security and employee voice as an alterative means of enhancing the health of the workforce and the performance of the organisation. Originality/value This paper elaborates on recent critiques of worker well-being programmes (see e.g. Guest, 2017), offering a comprehensive and robust theoretical framework. The paper cites extensive evidence that improved pay, employment security and an effective voice in the workplace are more effective means of meeting the needs of the firm and improving worker well-being.

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.

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.
