Gold mineralization on the Marn property, Yukon, occurs in two pyroxene skarn bodies, which are adjacent to the Mount Brenner Stock in the Ogilvie Mountains. The skarns are separated by a 600 m wide monzonite intrusion and show contrasting mineralogical and geochemical characteristics in addition to quite different metal values. Significant but uneconomic Au, Ag, W, and Cu mineralization is found in skarn on the north side of the intrusion, while very low Au grades (0.052 g/t) occur at the southern contact. The mineral assemblages of both skarns are dominated by iron-rich pyroxenes. The iron content of the pyroxenes varies between Hd40 and Hd80 in the northern location and Hd80 and Hd100 in the southern skarn. A well-developed sequence of retrograde alteration affected only the northern skarn. This was probably the result of porosity and permeability differences in the early, high-temperature pyroxene skarn, which permitted greater fluid–rock interaction in the northern skarn during cooling. A small volume of diopsidic, aluminous, wollastonite-bearing skarn occurs in both the northern and southern localities. The relationship of this type of skarn to the hedenbergitic skarn is ambiguous, since there is no large-scale mineralogical zoning. The Marn is similar to hedenbergitic, auriferous skarns of Japan, where the oxidation state of the intrusive rocks is believed to be the controlling factor in the development of skarn mineralogy.

As it is well known that, formation porosity and permeability are fundamental rock properties. Porosity is a measure of the storage capacity of the rock and permeability is a measure of rock flow capacity. In this study the relationship of the scale effect with the features and type of the capacitive structure of complex reservoirs is shown. The characteristic conditions for the manifestation of large-scale effects in determining porosity and permeability are analyzed. Also in this work the influence of the scale effect on the representativeness of laboratory determinations of flow- storage capacitance (FSC) properties is shown. The relationship between the values of porosity and permeability with the object of the core study has been established.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

AbstractIn 1789 in Leipzig, a slim pamphlet of 128 pages appeared that sent shock waves through the German republic of letters. The pamphlet, bearing the title Mehr Noten als Text (More notes than text), was an ‘exposure’ whose most sensational element was a list naming numerous members of the North German intelligentsia as initiates of a secret society. This secret society, known as the German Union, aimed to push back against anti-Enlightenment tendencies most obviously manifest in the policies promulgated under the new Prussian king Frederick William II. The German Union was the brainchild of the notorious theologian Carl Friedrich Bahrdt (1741–92). But who was responsible for the ‘exposure’? Using material culled from several archives, this article pieces together for the first time the back story to Mehr Noten als Text and in doing so uncovers a surprisingly heterogeneous network of Freemasons, publishers, and state officials. The findings prompt us to reconsider general questions about the relationship of state and society in the late Enlightenment, the interplay of the public and the arcane spheres and the status of religious heterodoxy at this time.

Having written and compiled from memory, over 700 Setswana proverbs when he was briefly resident in London, around the 1900s, Sol T. Plaatje exhibited unusual ethnographic knowledge and remarkable, creative translation skills in diaspora-like circumstances.  While most literary researchers attest to those achievements, few have been the theories that account sufficiently for Plaatje's multilingual proverb renditions. The view propounded here is that Plaatje's paremiological enterprise was probably never only an exercise of his polyglot abilities. Rather his quest appears to have been to assert the cultural similarities and convergences between African and European people's histories.  His socio-political beliefs propelled deep pride over his Setswana identity and became the driving force for highlighting the human bonds among nations of the North and the South. For Plaatje, seeing the overlaps and equivalences in and through the proverbs of the Dutch, English, French, Germans and the Batswana peoples, firstly validated orality as the bedrock of modern literary expression.  Secondly, the relationship of the two seemed to recapitulate the communicative connections among people and their languages, across time and space. Lastly, the paper makes the point that Plaatje's search for unity in the cultural diversity as exhibited in his 1916 Diane tsa Setswana collection and the 1924 A Sechuana Reader stories, provides instructive lessons that present-day South Africa would ill afford to ignore considering the social cohesion challenges the nation faces.

Purpose The purpose of this paper is to investigate the effects of values of materialism on cognitive and affective impulsiveness and responsible financial behavior among young adults. Design/methodology/approach A large-scale study (n = 483) was conducted on a sample of young adults 18 to 25 years of age in Croatia. Findings The research found that materialism has no direct effect on responsible financial behaviour (RFB), however, cognitive impulsiveness fully mediates the relationship of all three there three elements of materialism, centrality, success and happiness and RFB. Affective impulsiveness has no effect on the relationship. Furthermore, only materialism as centrality strongly and positively influences cognitive and affective impulsiveness. Practical implications Presented conclusions could be used by policymakers as guidelines for developing educational plans and curriculum to build financial capability and consumer protection among young adults and could be helpful for brand management activities targeting young people purchase decisions. Originality/value This paper’s ultimate purpose is to uncover the mechanism and the power of materialism on impulsiveness and responsible financial behavior. The paper’s originality is established by the focus on the investigation of materialism as an antecedent factor of impulsiveness and by questioning the nature of the relationship between materialism and responsible financial behavior through the mediating effect of impulsiveness.

This study examines the connection between governance, financial performance, and financial difficulties of 27 conventional private banks during the pe3riod of 2015-2018. In order to meet the accuracy of the model in the regression analysis, the Lagrange Multiplier test was previously performed so that the Fixed Effects model was chosen. The relationship of insider ownership with ROA tends to be in the shape of inversed-U and the relationship between institutional ownership and ROA is significantly positive. The relationship between ROA and financial difficulties is significantly negative. Older or established large scale banks tend to have high ROA. This happens because the greater the assets, the healthier the cash flow of the bank, so that the potential for return of asset is quite high and financial difficulties tend to be low or avoidable.

In the decade and a half since economic liberalization began in Jordan, a little noticed but large-scale organizing trend has taken over the formal provision of social welfare, redefining the institutional conception of familial identity in the process. For over one third of the population, kin solidarities have been reorganized, formalized, and registered as nongovernmental organizations in an attempt to cope with the removal of basic social provisioning by the state. Although kinship clearly has been a major element in Jordan's history, the present phenomena alter traditional familial institutions, change kin lineages, and institutionalize the economic salience of family relations. In turn, the relationship of the populace to the state has changed, marginalizing previously regime-supporting groups and facilitating the implementation of economic neoliberalism without significant protest. Repackaged as charitable elements of civil society, these family associations are sanctioned and encouraged by the state and international community. Although they are not regime creations, family associations reinforce the Jordanian regime's efforts at political deliberalization. The new elites who head the organizations have been placated through indirect incorporation into the regime; they now wield significant economic power over fellow kin and have enhanced social status backed by the new group. Furthermore, the trend mainly consists of families without immediate ambitions of entering national politics. These are not the traditional elite families.

A large-scale, community-based survey was done to assess the frequency of a wide variety of sexual behaviors in normal preadolescent children and to measure the relationship of these behaviors to age, gender, and socioeconomic and family variables. A sample of 880 2-through 12-year-old children screened to exclude those with a history of sexual abuse were rated by their mothers using several questionnaire measures. The frequency of different behaviors varied widely, with more aggressive sexual behaviors and behaviors imitative of adults being rare. Older children (both boys and girls) were less sexual than younger children. Sexuality was found to be related to the level of general behavior problems, as measured by the Achenbach Internalizing and Externalizing T scores and to a measure of family nudity. It was not related to socioeconomic variables.

This chapter re-evaluates Felix Mendelssohn’s ‘Scottish’ works by placing them in the context of the early-nineteenth-century North German view of Scotland, especially as channelled through Mendelssohn’s mentors Johann Wolfgang von Goethe and Carl Friedrich Zelter. Such interest in Scotland was undergirded by a belief in a shared German-Celtic past and a sense that Scottish culture was not exotic but rather essentially German. Figures in Mendelssohn’s circle participated in deliberate attempts to claim a general northern antiquity for German culture, using arguments concerning the relationship of climate, race, and character. A recontextualization of Scotland as representing a lost German past may signal additional reinterpretations of Mendelssohn’s anticipations of travel, his travel experiences, and his statements concerning folk song, as well as his Fantasy, Op. 28, originally titled Sonate écossaise.
