Resumen
Trace elements with a low mobility and with a low transfer are Cu, As, Be, V, Cr, Hg. Copper has at low mobility an increased transfer quotient (content plant/soil). The lowest mobility and transfer show Cr and Hg. Only at the very high contents or increased mobilities of trace elements, which accompany the anthropogenic contamination, soil critical loading for crops can be attained. Because of the amount of the examined extremes, it was not possible to derive the proper critical values. Therefore we were able to assess only critical protective values. They represent minimum total contents of

Resumen
The study of ‘policy transfer’ has been subject to sustained criticism, in particular by critical policy studies scholars. This critique—together with the rather marginal role that policy transfer research has played in criminological debates to date—raises questions about the continued utility of such research in scholarly discussions of crime control and penal policy-making. However, we argue here that such studies can enhance our understanding of the local, national and global influences over crime control policy formation. In particular, the developing interest in comparative criminology,

Resumen
Physical travel has traditionally been viewed as an agent of transformation. The research conducted on this topic, however, is surprisingly narrow in scope. Few studies have attempted to look beyond a particular tourism/travel segment or discipline and most utilise a restricted range of methods and analysis. These investigations have also failed to consider the long-term impacts of corporeal travel and how changes continue to evolve over time. Drawing upon a holistic and interdisciplinary study of transformative travel, this article argues that in a mobile world, it becomes increasingly diffic

Texto completo
Resumen
Grain boundary networks composed of equal microstructural elements were investigated in a recent paper. In this work a more complicated artificial grain topology consisting of one four-sided, two six-sided and one eight-sided grain is designed to further investigate the influence of grain boundary and triple junction mobilities on the kinetics of the system in more detail. Depending on the value of the equal mobility of all triple junctions, the initially square-shaped four-sided grain changes its shape to become more or less rectangular. This indicates that the grain morphology is influenced

Resumen
Large group-I elements such as sodium, rubidium and cesium have recently been incorporated in the gate oxide of SiC power MOSFETs. In the case of sodium incorporation, enhanced field effect mobilities have been definitively observed. Based on density functional calculations, we find large group-I elements serve as a shallow impurities near the interface. The enhanced mobility, observed in the case of sodium, can be explained in terms of an impurity band model.

Resumen
Repetitive elements provide important clues about chromosome dynamics, evolutionary forces, and mechanisms for exchange of genetic information between organisms. Repetitive sequences, especially the mobile elements, have many potential applications in genetic research. DNA transposons and retroposons are routinely used for insertional mutagenesis, gene mapping, gene tagging, and gene transfer in several model systems. Once they are developed for the zebrafish, they will greatly facilitate the identification, mapping, and isolation of genes involved in development as well as the investigation o

Contemporary tourism is omnipresent in development discourses and policies, functioning as a "worldmaking" force in which tourism activities provide a representation and storyline that influence the tourist and their behavior, thus becoming a form of social production.

Texto completo
Resumen
A subduction zone plays a critical role in forging continental crust via formation of arc magmas, which are characteristically enriched in large ion lithophile elements (LILEs) and depleted in high field strength elements (HFSEs). This trace element pattern results from the different mobilities of LILEs and HFSEs during slab-to-wedge mass transfer, but the mechanisms of trace element transfer from subducting crusts are not fully understood. In this study, thermodynamic simulations are carried out to evaluate the mobilities of K and Zr, as representative cases of LILE and HFSE, respectively, in

Hall-effect and resistivity measurements of semiconductor alloys of the type Culn1−yGaySe2(1−x)Te2x have been made over the temperature range 77–300 K. All materials were p-type with mobilities in the range 1 < μ < 10 cm2/V∙s. The observed electrical properties are interpreted in terms of the presence of intrinsic defects arising from dissimilar evaporation of the constituent elements of the materials during melting and annealing stages.

Resumen
AbstractThe hospitality industry faces significant challenges from the acceleration of travelers using mobile technology, especially in the Covid-19 aftermath. Consumer behaviour is changing in the service sector, creating new forms of mobilities and types of tourists. Users are taking advantage of the opportunity to access information easier and faster, anywhere causing new promotional strategies for hospitality businesses. However, it is recognized that the adoption of mobile applications does not guarantee competitive advantage. This research is inspired by the success of mobile games, and the importance of delivering fun. It explores hotel visitors’ meaning of ‘fun’ when using a mobile hotel gamified application. This is to give mobile gamified application developers an indication on the fun elements that would make such a technology engaging with the users. Visual materials were used applying game mechanics and aesthetics in a hotel application helping participants understand how the fun elements are incorporated so they can focus/target on the elements they find more attractive.

Resumen
The border is framed as a political/administrative element, as a space of contact of cultures and geographies, as a line of separation and permeability, generator of mobilities of different scales. During the last decades, the Iberian border has experienced depopulation dynamics and socio-economic reorganisations that have transformed the ways of working, the models of social organisation, occupation, and land use. In this context of growing mobility, tourism has become an important activity for the border due to its ability to generate employment and foster economic and social development. The mobilization of natural and cultural resources assumes significance in the valorization of these spaces, in line with the current policies of cross-border cooperation promoted by the EU and the efforts of the two Iberian countries. The border between central Portugal and Spain is taken as a study object, highlighting the existing dynamics and forms of cooperation, given the heritage values, capable of generating new attractions and functions in the oldest European border.

Texto completo
Resumen
Although politicians previously nodded in the direction of social mobility, it was under New Labour that it became an increasingly frequent element in manifestos, ministerial speeches and policy proposals. This chapter traces mobility’s rise up the political agenda to today, showing how and when politicians invoked mobility as a solution to problems of social inequalities. Mobility ceased to be a topic of academic research as it was taken up by the politicians. Despite different stances among the parties, there was a consensus that mobility rates were low, had been declining and were lower than other countries. Calling for ‘more mobility’ neglects downward mobility. On the back of this mistaken interpretation, a veritable ‘social mobility industry’ has grown up since 2000, supported by extensive media coverage.

Resumen
Supported by government funds, many Jewish communities were able to renovate or build new synagogues beginning in the 1950s, a development that peaked around 1960. The organ, however, once a visual and aural symbol of Reform and acculturation could hardly be found in the new sacred spaces and was even removed from existing ones. With regard to the organ in the synagogue, cultural mobility’s obliqueness between change and persistence or continuity does not quite apply in the postwar era. Change had already occurred with the pogroms of November 1938, when the vast majority of instruments were destroyed. As one of the least fixed elements of Jewish musical practice, the organ still left its mark in postwar Germany in different ways: absence, silent presence, and adapted or modified presence. While being a nearly immovable artifact and a constituent of Jewish culture in later modernity, in the postwar era it embodied the near absence of liberal Judaism.
