Organic charge transfer complex at the boundary between superconductors and insulators: critical role of a marginal part of conduction pathways

κ-ET2Cu[N(CN)2]I (ET = bis(ethylenedithio)tetrathiafulvalene) has previously been reported as both a superconductor and an insulator. Examination of each single crystal revealed that the electrical properties are governed by slight differences...

Prospects for the oil and gas content of the Upper Permian deposits of the southwestern part of the Vilyui syneclise based on the analysis of sedimentary environments and geochemical conditions of oil and gas content

The article discusses the prospects for the oil and gas content of the Upper Permian deposits in the southwestern marginal part of the Vilyui syneclise. In this margin, the Permian terrigenous complex with proven oil and gas productivity in the central part of the syneclise, pinches out. The study area, represented by the monoclinal slopes of the Vilyui syneclise, is considered a promising area for the exploration of non-structural hydrocarbon traps in the Upper Paleozoic sediments. The objectives of the study include identifying general patterns of sediment formation, associated mainly with the development of the alluvial complex, and substantiating the potential opportunities of migration and accumulation of hydrocarbons in the predicted traps. The research is based on the interpretation of the latest seismic surveys and prior-years geological and geophysical data. Authors carried out structural and paleo-structural analysis, identified lithofacies in the well log, generalized and analyzed the geochemical conditions of the oil and gas content of the Upper Permian deposits, traced the pinching out of the Upper Permian deposits on the southwestern margin of the syneclise, and also outlined areas of river valleys development that form zones of advanced reservoirs. The results of the studies have validated promising oil and gas accumulation zones on the southwestern slopes of the syneclise associated with non-anticlinal hydrocarbon traps. Authors also drew up a diagram of the oil and gas potential of the Upper Permian deposits. The obtained results are of interest for prospecting for oil and gas in the area under study.

'La Vérité emphatique du geste dans les grandes circonstances de la vie' : Baudelaire, Barthes and the Hysterical Gesture

To associate Baudelaire and Barthes may seem a somewhat unlikely gesture. Barthes wrote about Baudelaire in a sustained way only once and with reference to a marginal part of the poet’s work, namely his failed theatrical projects. Yet Baudelaire remains a point of reference across the entire span of Barthes’s career, in particular as the author of a frequently cited quotation from ‘Exposition Universelle’ (1855): ‘la vérité emphatique du geste dans les grandes circonstances de la vie’. This phrase punctuates Barthes’s published work throughout, from one of his earliest essays to his very last book on photography, and is closely associated with another persistently recurring motif: the concept of numen, a term used to designate a static gesture expressing divine authority. The aim of this article is to examine the significance of Baudelaire for Barthes by investigating how he deploys the quotation from the ‘Exposition Universelle’ essay and the intertwined concept of numen. Its guiding questions are: what does Baudelaire mean for Barthes? And what does that tell us in turn about Baudelaire? Answering these questions involves tracing the intersecting trajectories of quotation and concept across Barthes's work, with a particular focus on the value to be attributed to exaggeration or excess in the communication of meaning through gesture and language, a phenomenon that both Barthes and Baudelaire associate with hysteria, as either something to be ironically assumed (Baudelaire) or ambivalently exorcized (Barthes).

When Does Expanded Eligibility Translate into Increased Take-Up? An Examination of Parental Leave Policy in Luxembourg

This article aims to explore the role of eligibility for parental leave as a determinant of access and as an enabler of leave take-up. To analyse the link between eligibility and take-up, we study a unique policy change in Luxembourg’s parental leave scheme. The country’s 2016 parental leave reform relaxed the eligibility criteria to enable marginal part-time working parents to access the parental leave scheme for the first time. We focus on this change and examine to what extent relaxing the eligibility criteria translated into increased take-up by the marginal part-time working parents who became eligible. To quantify this transition, we analyse trends in and patterns of eligibility for the scheme in Luxembourg between 2009 and 2018 among first-time parents working full-time, part-time, or marginal part-time hours. We use a subsample of Luxembourg-resident, cohabiting, first-time parents (N = 6,254) drawn from the social security data. Our analysis shows that as eligibility is dependent on individual factors, it has similarities among mothers and fathers, whereas take-up is notably greater for mothers. After the reform, we observe that marginal part-time working mothers started taking parental leave, but up to 2018, the reform’s outreach to marginal part-time working fathers remained limited. We also find that foreign national parents are less likely to be eligible for parental leave and have lower take-up rates. Despite the gendered parental leave take-up behaviours in parallel with international evidence, marginal part-time working mothers’ positive response to the reform indicates progress towards strengthening women’s labour market attachment in Luxembourg.

Self-Concept and Time Perspective of Convicts

Objective: The purpose of the article is to connect the time perspective of the convicts with their self-concept. Background: After an extended stay in places of deprivation of liberty, it is difficult for convicts to adapt to the conditions of life in freedom, to restore the social ties that were lost and weakened due to isolation. And therefore, they often fall into the marginal part of the population, cannot find their place in life, and often replenish the number of unemployed or, even worse, re-enter the criminal path and commit crimes. Method: The following psychological methods were used: the technique of “Who am I?”, which allowed studying the cognitive component of the self-concept; the methodology of personal differential that provides an opportunity to study the emotional component of the self-concept; the self-attitude test questionnaire and the method of F. Zimbardo allowed to determine the main features of the time perspective. Results: The article reflects the study of convicts based on which a typology of “self-concept” of convicts was proposed. Besides, the results of a study of the temporal perspective of convicts depending on the type of self-concept are presented. Conclusion: The authors are inclined to believe that a detailed study of this problem will identify and provide effective ways to stimulate the constructive resocialization of various categories of prisoners.

Orthoptera assemblages of the relict meadows of the Szernye marsh area (West Ukraine: Transcarpathia)

Orthoptera assemblages were sampled between 2012 and 2014 on six grasslands in marginal part of the former Szernye Marsh (Bereg Lowland, Transcarpathia, West Ukraine). 24 species in 1306 individuals were observed which is about the half of the Orthoptera species known from the Bereg Lowland. The bulk of the assemblages is formed by generalist chortobiont species (62.5%), while thamnobionts, connected with tall forb and/or shrubby vegetation, also reach a relatively high frequency (29.1%). According to the biogeographical composition, the Euro-Siberian species were predominating (58.3%), combined with only scarce presence of West Palearctic and Mediterranean species. The multivariate analysis did not show any clear subdivision according to the a priori vegetation types with the exception of the xeric habitats. This assemblage type were characterised by a low species number (7–12) and very high frequency of one or at least two dominant species which were common in all types of studied habitats. Although their subdominant species differed from the other two assemlage types but they could not be referred as true character species. Thus the studied xeric habitats are not such true xeric grasslands as the sandy and saline grasslands of the Pannonian lowland. The main natural value of the area is preseved by semi-natural humide and transitional habitat types, which can be conserved by yearly alternating mowing and preserving the mosaic structure with some corridors among them.

Evolution of Syenite Magmas: Insights from the Geology, Geochemistry and O-Nd Isotopic Characteristics of the Ordovician Saibar Intrusion, Altai-Sayan Area, Russia

In this paper, we provide insight into the evolution of syenite magmas based on geological data and petrographic, geochemical, and O-Nd isotope parameters of rocks of the Saibar intrusion located within the Minusinsk Trough, Altay-Sayan area. The intrusive suite includes predominant syenites, few bodies of melanocratic and leucocratic nepheline syenites (foyaites), and granites. In addition, dykes of granites and mafic rocks are present. The U-Pb zircon age from the melanocratic foyaites was determined to be 457 ± 27 Ma. Examined rocks show fractionated light rare earth element patterns, normalized to chondrite, with (La/Sm)n varying from 4 to 9, and a weakly fractionated distribution of medium and heavy rare elements, with (Dy/Yb)n from 0.35 to 1.23 and (Sm/Yb)n from 0.63 to 2.62. The spidergram normalized to the primitive mantle shows negative Ba, Sr, Nb, Ta, Ti, and Eu anomalies (Eu* = 0.48–0.60) and positive Rb, Th, and U anomalies. The δ18O values vary within 6.3 to 10.2‰, and εNd(t) from +4.1 to +5.0. We observe gradual transitions from syenites to foyaites. Assimilation by syenite magma of the host carbonate rocks was followed to transition from silica-saturated to silica-undersaturated conditions and removal of anorthite from the melt, which then led to nepheline. Granites of the main phase show depleted lithophile incompatible elements in comparison with syenites and foyaites. They originate via interaction of magmas at the marginal part (endocontact zone) of the intrusion, corresponding to north contact of the granites with the host felsic rocks. In comparison, the rock composition of granite dykes is enriched in lithophile incompatible elements, except for Zr, Hf, and Ti. These rocks are formed due to the differentiation of syenite magma without a significant effect of host rock assimilation. Mantle magmas must be used as parent magmas for syenites based on analysis of the formation model of other alkaline intrusions, which are similar in age to the Saibar intrusion. In the line of syenite intrusions of the Altai-Sayan province, the Saibar intrusion is no exception, and its origin is related to the evolution of mafic magmas that arose during the melting of the mantle under the influence of a mantle plume.

SOME ASPECTS OF LOCALIZATION OF PRECIOUS METAL MINERALIZATION IN THE LOWER PERMIAN CONGLOMERATES WITHIN THE NORTH-EASTERN PART OF THE O-40-XXIX SHEET (SHALINSKAYA PLOSHAD)

“Metal-bearing” conglomerates are known in various regions of the world. They are associated with ore occurrences and industrial deposits of gold, uranium, silver, iron, copper and other minerals. At the junction of the Western marginal part of the West Ural folding zone with the pre-Ural regional trough, rocks were recorded, during petrographic and mineralogical studies of which it was possible to establish direct (signs of gold) and indirect signs of gold localization in the lower Permian polymictic conglomerates and in the eluvial weathering crusts formed along them.

Marginal Part-Time Employment in Indonesian Labor Market: Profile and Determinant

The increase of marginal part-time employment has been found in developed countries, as well as in developing countries. This form of non-standard employment has very short work hours (less than 15 hours/week) and no guarantee of stable employment. In Indonesia, the share of part-time worker amongst working population increased from 15.4 percent in 2009 to 22.1 percent in 2018. Unfortunately, few studies discuss about marginal part-time employment. Using binary logistic regression, this study aims to identify marginal part-time workers based on their socio-demographic characteristic. The result indicates that female (OR: 1.81; 95% CI: 1.75-1.87), living in rural area (OR: 1.12; 95% CI: 1.08-1.16), and less educated are more likely to be marginal part-timer. Therefore, it is recommended for policymakers to ensure the labor regulation adequately protect the rights of part-time worker, so that the workers condition can be improved since they are most vulnerable group in the globalized economy.Keywords: non-standard employment, labor market, part-time, Indonesia Pekerja Paruh Waktu Marjinal Pada Pasar Tenaga Kerja Indonesia: Profil dan DeterminanAbstrak: Peningkatan pekerja paruh waktu marjinal telah teramati pada negara-negara maju dan juga negara berkembang. Salah satu bentuk pekerjaan non-standar ini memiliki jam kerja yang sangat pendek (kurang dari 15 jam seminggu) dan tidak adanya jaminan kestabilan pekerjaan. Di Indonesia, proporsi pekerja paruh waktu diantara penduduk bekerja meningkat dari 15,4 persen pada 2009 menjadi 22,1 persen pada 2018. Sayangnya, hanya sedikit studi yang membahas tentang pekerjaan paruh waktu marjinal. Dengan menggunakan regresi logistik biner, studi ini bertujuan untuk mengidentifikasi pekerja paruh waktu marjinal berdasarkan karakteristik sosio-demografinya. Hasil menunjukkan bahwa perempuan (OR: 1,81; 95% CI: 1,75-1,87), penduduk desa (OR: 1,12; 95% CI: 1,08-1,16), dan kurang berpendidikan berisiko lebih besar menjadi pekerja paruh waktu marjinal. Oleh karena itu, direkomendasikan bagi pembuat kebijakan untuk dapat memastikan peraturan ketenagakerjaan cukup untuk melindungi hak-hak pekerja paruh waktu khusus yang termarjinal agar kondisi pekerja dapat ditingkatkan karena mereka adalah kelompok paling rentan dalam ekonomi global.Kata kunci: pekerjaan non-standar, pasar tenaga kerja, paruh waktu, Indonesia
