New samples of jaskólskiite were recently collected at the Aurélia II siderite-type hydrothermal vein with sulphides near Rožňava, Spišsko-gemerské rudohorie Mts., Rožňava Co., Košice Region, Slovakia. It forms lead-gray, irregular aggregates up to 1.5 × 1 cm in size, which are enclosed in quartz-siderite gangue. Aggregates of jaskólskiite are consisting of individual, subhedral acicular crystals to 2 mm long, strongly replaced by younger bournonite and associated with Bi-rich jamesonite, tetrahedrite-(Fe), tintinaite, native bismuth and ullmannite. Significant variation of Cu (from 0.04 to 0.23 apfu) and Bi contents (from 0.32 to 0.77 apfu) was observed in studied sample. The average (n = 69 analyses) empirical formula of jaskólskiite from Rožňava-Aurélia vein based on Pb+Bi+Sb = 4 apfu is corresponding to Pb2.11Cu0.13(Sb1.42Bi0.47)1.89S5.14. Bi-rich jamesonite is the most common sulphosalt at the studied locality and it forms prismatic crystals up to 2 cm or irregular aggregates to 3 cm in size. The Bi content in jamesonite is ranging between 0.49 to 1.69 apfu. Bournonite is also common and two compositional types were distinguished. The first, dominant type is represented by Bi-rich bournonite (containing up to 0.14 apfu Bi). The second type of bournonite, represented by thin ribbons shows significant enrichment in As (reaching up to 0.49 apfu), but has only minor content of Bi (up to 0.08 apfu). Tintinaite is rare and its average (n = 9) empirical formula based on sum of all atoms = 63 apfu is corresponding to (Pb9.67Ag0.06)9.73(Cu2.55Fe0.40Zn0.07)3.02(Sb10.19Bi5.37)15.56S34.59Cl0.10.

A new occurrence of nuffieldite was recently discovered in a siderite-type hydrothermal vein with sulphides in Došťavná near Slovinky, Spišsko-gemerské rudohorie Mts., Spišská Nová Ves Co., Košice Region, Slovakia. It forms lead-gray acicular crystals reaching up to 1 cm in size or aggregates up to 2.5 cm, which are enclosed in quartz-siderite matrix together with chalcopyrite, pyrite, tourmaline and chlorite. Nuffieldite is frequently replaced by minor aikinite, galena and native bismuth. The refined unit-cell parameters of nuffieldite (for the orthorhombic space group Pbnm) are: a 14.5313(16) Å, b 21.454(2) Å, c 4.0500(6) Å and V 1262.58(19) Å3. The average (n=145 analyses) empirical formula of nuffieldite from Slovinky-Došťavná based on Pb+Bi+Sb = 5 apfu is corresponding to Cu1.30Pb2.00Bi2.00(Pb0.30Bi0.30 Sb0.40)1.00(S7.12Se0.03)7.15. Aikinite forms microscopic, anhedral to subhedral grains or aggregates replacing nuffieldite. The average (n=29) empirical formula of studied aikinite based on (Cu+Pb)/2+(Sb+Bi) = 8 apfu is Pb3.83Cu3.76(Bi4.12 Sb0.09)4.21(S12.40Se0.03)12.03.

AbstractWatanabeite Cu4(As,Sb)2S5, in which As>Sb, is a new copper sulphosalt that occurs with quartz in a hydrothermal vein at the Teine mine, Sapporo, Hokkaido, Japan. It is silvery lead-grey in colour with lead-grey streak. VHN100 = 253-306 kg/mm2, brittle. It has no cleavage and the fracture is uneven. The measured density = 4.66(2) g/cm3. The mean of six microprobe analyses gave Cu 41.1, Ag 0.1, Mn 0.3, As 15.4, Sb 14.3, Bi 2.4, S 26.2, a total of 99.8 wt.%, corresponding to: (Cu3.94Mn0.03− Ag0.01)∑3.98(As1.25Sb0.72Bi0.07)∑2.04S4.98 (basis: total atoms = 11), or ideally, Cu4(As,Sb)2S5, with As > Sb. The X-ray powder pattern resembles that of tetrahedrite but has subsidiary diffractions and is similar to that of synthetic Cu24As12S31 (Maske and Skinner, 1971). It is indexed on an orthorhombic cell with a = 14.51 Å, b = 13.30 Å, c = 17.96 Å (all ± 0.01 Å), and Z = 16. Calculated density is 4.66 g/ cm3. It is optically similar to tetrahedrite but is grey and weakly bireflectant. No internal reflections were observed. The maximum and minimum reflectance values in air and in oil (nD = 1.515) for the COM wavelengths are: 470 nm −32.5, 31.5; 17.7, 17.0, 546 nm −32.0, 31.1; 17.0, 16.3,589 nm −31.1, 30.3; 16.1 m 15.5, 650 nm −30.0, 29.3; 15.0, 14.5%, respectively. Watanabeite forms masses composed of aggregates of minute grains up to 50 μm in diameter. Apart from some minute inclusions of emplectite, native bismuth and tennantite, it is almost monominerallic.

This study deals with politeness strategies in political language. The aim of the study is to describe how Indonesian politicians realize politeness in their language. The subject was taken nine parties who have representatives. They come from different parties: Democrat, Golkar, PDIP, PKS, PPP, PKB, PAN, Gerindra and Hanura. Data were classified and verified with reference to the criteria of politeness strategies as determined by Brown & Levinson (1987); cover the bald on record strategy, positive strategy, negative strategy and off-record strategy. The finding show that there were four types of politeness strategies used by Politicians in different of types of illocutionary acts; positive strategy, bald on record strategy, negative strategy, and off-record strategy. The most dominant type of politeness strategies used was positive strategy. The most dominant type was due to fact that speakers in interaction try to get closer the hearers. They use the group identity marker in addressing someone so there is no distance relationship between the speaker and hearer. They also gave the reasons when they speak in order to satisfy the hearer. Key words: politician; political language; politeness strategy

The article is devoted to the analysis of the process of generating social meanings on the area of European civilization. Authors assign a separate place to the research of the tendency of increasing social activity in local communities, which accompanies decentralization processes in modern Ukraine. The article analyzes the characteristic features of non-tribes, based on the M. Maffesoli’s concept of “neo-tribalism”, and traces the tendency of reactualization a partly transformed communal way of life of modern tribes. The authors investigate the retrieval of the request for a valuable education in society. It is emphasized on the growing tendency of the filling of the meaning of the professional activity of public administrators, according to the significant request of providing public interests and collective goals by citizens. The authors singled out a new role of public administration — providing public education. In the context of this problem, the authors substantiate the critical need for a successful completion of the authority decentralization reform in Ukraine. Proceeding from the process of neo-tribalism that covers modern Europe, the authors predict the emergence of a new collective identities on the European area. The authors point to a characteristic tendency: Ukrainians are deeply embedded in solving internal problems of society, which manifests in the correction of gaps in cultural and educational policies of past years, self-organization (through volunteer and volunteer movements), civil responsibility for the welfare of their communities, and participation in the management of local affairs. According to the authors, this tendency influences the dominant type of future sociality (it is not the individual “Me”, but “Me as a part of community”).
