Rundqvistite-(Ce), ideally Na3(Sr3Ce)(Zn2Si8O24), is a new mineral from the Darai-Pioz alkaline massif, Tien-Shan Mountains, Tajikistan. The mineral occurs as elongated grains up to 0.1 mm long and up to 0.03 mm thick embedded in quartz–pectolite aggregate in a silexite-like peralkaline pegmatite. Associated minerals are quartz, fluorite, pectolite, baratovite, aegirine, leucosphenite, neptunite, reedmergnerite, orlovite, sokolovaite, mendeleevite-(Ce), odigitriaite, pekovite, zeravshanite, kirchhoffite and garmite. The mineral is colourless with a vitreous lustre and a white streak, brittle, Dmeas. is 3.70(2) and Dcalc. is 3.709 g/cm3. Rundqvistite-(Ce) is monoclinic, space group P21/c, a = 5.1934(16), b = 7.8934(16), c = 26.011(5) Å, β = 90.02(3)° and V = 1066.3(4) Å3. The chemical composition of rundqvistite-(Ce) is SiO2 40.17, La2O3 2.64, Ce2O3 7.55, Pr2O3 0.80, Nd2O3 2.43, Sm2O3 0.33, Eu2O3 0.09, Gd2O3 0.24, Tb2O3 0.18, Dy2O3 0.21, PbO 1.03, SrO 19.83, FeO 0.37, ZnO 13.08, CaO 2.55, Na2O 8.04, total 99.54 wt.%. The empirical formula calculated on 24 O apfu (atoms per formula unit) is Na3.10Sr2.29Ca0.54Pb0.06(Ce0.55La0.19Nd0.17Pr0.06Sm0.02Gd0.02Eu0.01Tb0.01Dy0.01)Σ1.04Zn1.92Fe0.06 Si8.00O24 Z = 2. The structural formula based on refined site-occupancies is (Na2.94Sr0.06)Σ3.00 [(Sr2.23Ca0.54Pb0.06Na0.13)Σ2.96Ln3+1.04]Σ4.00[(Zn1.92Fe2+0.06)Σ1.98Si8O24], where Ln3+1.04 = (Ce0.55La0.19Nd0.17Pr0.06Sm0.02Gd0.02Eu0.01Tb0.01Dy0.01)Σ1.04. The crystal structure of rundqvistite-(Ce) was refined to R1 = 2.76% on the basis of 3184 unique reflections [F > 4σ|F|]. In rundqvistite-(Ce), the main structural unit is a (Zn2Si8O24)12– sheet parallel to (100). In the sheet, the Si and Zn tetrahedra form four-, five- and eight-membered rings. The interstitial cations at the Na and M(1–3) sites sum to [Na3(Sr3Ce)]12– apfu. The Na and M(1–3) polyhedra share common edges to form a layer. Rundqvistite-(Ce) is a structural analogue of vladykinite, ideally Na3Sr4(Fe2+Fe3+)Si8O24. Rundqvistite-(Ce) and vladykinite are related by the following substitution: [8]Ce3+ + [4](Zn2+)2 ↔ [8]Sr2+ + [4](Fe2+Fe3+). The mineral is named after Dmitry Vasilievich Rundqvist (1930–2022), a prominent Russian geologist and an expert on the geology of ore deposits, metallogeny and mineralogy of Precambrian rocks.

This article explores post-Soviet power hierarchies which constitute a unique system of vertical stratification in world politics. It does so by analysing relations between two former Soviet states, Tajikistan and Russia, in the aftermath of the Soviet Union’s collapse in 1991. The article investigates the underlying reasons for power asymmetries between the two countries, the ways hierarchies are sustained and enforced, as well as perceived and navigated at political and social levels. It is argued that Tajikistan’s relations with Russia are explicitly postcolonial without clear-cut colonial precedents in Soviet times. Postcolonialism did not automatically result from the Soviet breakdown. Rather, it has gradually emerged because of the two countries’ very different paths of integration into the global capitalist economy, which subordinated Tajikistan to Russia. In this way, new economic asymmetries exacerbated Soviet-era legacies and reinvented them in a new, hierarchical manner. Overall, the article contributes to the debate on the nature of post-Soviet legacies and what it means to be post-Soviet.

An inscription in the name of a Kushan king, Wima Takto (circa 90–113 CE), has recently been discovered by the archaeologist Muhsin Bobomulloev of the National Museum of Tajikistan and his colleagues. The new inscription, found in the Almosi Gorge with other inscriptions in an ‘unknown script’, confirms the identity of Wima Takto, the second king of the Kushan Dynasty, which ruled a large territory stretching from Central Asia to North India in the first four centuries CE. The history of this dynasty is pieced together from inscriptions, coins, and archaeology, and fleeting references in Chinese sources. Each new inscription adds another piece to the jigsaw of Kushan history, revealing a powerful state in control of the central lands of the ancient Silk Road. This article positions the new inscription within the current understanding of Kushan history and the status of Wima Takto.

Kalyuzhnyite-(Ce), ideally NaKCaSrCeTi(Si8O21)OF(H2O)3, is a new mineral from the Darai-Pioz alkaline massif, Tien-Shan mountains, Tajikistan. It occurs as equant grains up to 0.05 × 0.07 mm in a quartz–pectolite aggregate in a silexite-like peralkaline pegmatite. Associated minerals are quartz, fluorite, pectolite, baratovite, aegirine, leucosphenite, neptunite, reedmergnerite, orlovite, sokolovaite, mendeleevite-(Ce), odigitriaite, pekovite, zeravshanite, kirchhoffite and garmite. The mineral is colourless with a vitreous lustre and a white streak, and Dcalc. is 3.120 g/cm3. Kalyuzhnyite-(Ce) is monoclinic, P2/c, a = 18.647(4), b = 11.214(2), c = 14.642(3) Å, β = 129.55(3)° and V = 2360.9(11) Å3. The chemical composition of kalyuzhnyite-(Ce) is Nb2O5 0.53, TiO2 0.16, SiO2 43.85, Er2O3 0.13, Ho2O3 0.10, Gd2O3 0.09, Sm2O3 0.47, Nd2O3 6.22, Pr2O3 1.21, Ce2O3 6.34, La2O3 0.82, PbO 4.90, BaO 0.85, SrO 11.39, CaO 1.86, Cs2O 3.80, K2O 1.59, Na2O 2.99, H2O 5.24, F 1.55, O = F –0.65, total 100.31 wt.%. The empirical formula calculated on 26.11 (O + F) apfu is Na1.07K0.37Cs0.30Sr1.21Ca0.37Pb0.24Ba0.06(Ce0.43Nd0.41Pr0.08La0.06Sm0.03Gd0.01Er0.01Ho0.01)Σ1.04(Ti0.97Nb0.04)Σ1.01Si8.06O25.21F0.90H6.42, Z = 4. The simplified formula is (Na,□)(K,Сs)(Ca,Pb,Sr,Na)SrLn3+Ti(Si8O21)OF(H2O)3, where Ce is the dominant lanthanoid. The crystal structure was solved by direct methods and refined to an R1 index of 2.74%. In kalyuzhnyite-(Ce), the main structural units are a heteropolyhedral Na–Sr–Ce–Ti sheet, ideally [NaSrCeTiOF]7+, and a double (Si8O21)10– sheet parallel to (010). In the Si–O sheet, the Si tetrahedra form ten-membered rings. This is the first occurrence of such a double Si–O sheet in a mineral. The two sheets connect via common vertices of Na-, Sr-, Ce- and Ti-polyhedra and SiO4 tetrahedra to form a framework. The interstitial cations and H2O groups, ideally [(CaK)(H2O)3]3+, occur within the Si–O sheet. The mineral is named in honour of Vasily Avksentievich Kalyuzhny (1899–1993) in recognition of his contributions to the geology of ore deposits of Komi Republic (USSR) and the mineralogy of granitic pegmatites (Tajikistan).

Soft power draws attention to the way governments, and other actors, create a positive image of themselves so that they can attract others and influence them. In this article, we examine how Russia and China use education to implement soft power in Tajikistan and the differences between the two approaches. This article examines academic diplomacy and the role of educational programs and research collaboration in the projection of China and Russia’s soft power in Tajikistan. We conclude that a latent geopolitical rivalry exists between the two great powers that is manifesting itself in a number of ways. Russia is in a stronger position to project soft power in Tajikistan, and, although the escalation of the war in Ukraine in February 2022 will undermine this influence, China will not displace Russia’s soft power in the near future.

For centuries, European operas have portrayed dramatic, exotic Others on stage. However, as opera is increasingly adopted around the world, including by those “Eastern” Others it orientalized, its Othering tendencies serve new, more critical purposes. Post-colonial studies of knowledge and cultural production have shown how relations between centers and peripheries, knowledge and power are integral to forms of orientalism. In Tajikistan, the accounts of opera told today by the daughter of a successful Soviet Tajik composer bring to light the ambiguity of power relations and positionalities in Soviet opera’s production. Her accounts, beyond highlighting opera’s readily apparent orientalist tendencies, reveal surprising cosmopolitan aspirations in Soviet Central Asian opera. Cosmopolitan histories and values also feature heavily in post-colonial politics of knowledge production, but the concept appears worlds apart from, even in opposition to that of orientalism: the latter feeds off center-periphery, knowledge-power relations, while the former aspires to evade them. Through this present-day account of opera’s development in Soviet Tajikistan, this article challenges this opposition, theorizing a conceptual ambiguity and interdependence between orientalism and cosmopolitanism, which has important consequences for knowledge-producing fields like opera, as well as anthropology. Multiple forms of orientalism and cosmopolitanism overlapped and interacted in the development of Soviet Central Asian opera as numerous, intersecting meanings and socio-political agendas went into its production. Ultimately, a conceptual space emerges between the orientalism(s) and cosmopolitanism(s) at play. This ambiguous space in-between offers a lens for critically evaluating the complex, uneven practice of portraying and engaging with Others.

The results of combined single-crystal X-ray diffraction, electron probe microanalysis, Fourier microspectroscopy, and photoluminescence spectroscopy study of crystals of turkestanite from the Dara-i-Pioz deposit, Tien-Shan Mountains, Tajikistan are reported. It is a single-layer sheet silicate belonging to the ekanite group with a steacyite structural type. Averaged major-element analysis provided (wt.%): K2O 4.13(6), CaO 8.1(1), Na2O 2.3(1), ThO2 25.8(4), UO2 3.6(4) and SiO2 55.9(1). The averaged crystal-chemical formula for the studied turkestanite is (Th0.84U0.12)Σ0.96(Ca1.24Na0.65)Σ1.89(K0.75☐0.25)Σ1.00Si8O19.72(OH)0.28. Single-crystal structural refinement of turkestanite gave tetragonal, space group P4/mcc, a = 7.5708(3) Å, c = 14.7300(11) Å, V = 844.27(6) Å3 and Z = 2. Luminescence of the uranyl ion (UO2)2+ is observed in turkestanite. In the excitation spectrum, the bands corresponding to a charge transfer transition from the 2p states of the ligand to the 5f state of uranium were found.

Despite being in operation for a mere five years, the Soviet-era Tajik (Persian) journal Rahbar-i Dānish (1927–1932) was a key venue for exploring and debating the merits of Tajik literature in the context of new ideological and literary trends. Established litterateurs as well as literary newcomers published examples of their literature and literary criticism in this first Tajik monthly social, educational, and literary journal. The present article reviews the history of Rahbar-i Dānish and some of its authors to trace their influence on Tajik literature and literary criticism in the late 1920s and early 1930s. The article addresses the difficulties of creating a Soviet Tajik literature and scrutinizes the various genres featured in the literary section of the journal. Finally, it presents the trajectories of two literary newcomers, Jalāl al-Dīn Ikrām (who later became known as Jalol Ikromi) and Baḥr al-Dīn ʿAzīzī (who died in a Soviet prison in 1944), whose short stories were most prominent in Rahbar-i Dānish. This article is based on an almost complete set of the forty-five issues of the journal, published between August 1927 and March 1932.

In scholarship on post-Persianate literary modernity, the emergence of the new institution of literature is often conflated with the delimitation and reification of national cultures as different manifestations of a single process. This article examines three anthologies of Persian literature from the interwar Persophone Soviet Union to reconsider the relationship between state cultural institutions’ procedures of literary modernization and nationalization. The anthologies mark out the stages by which classical Persian literature was portioned out to Soviet Eastern nationalities, and in particular the advent of Tajik literary history, but they also reveal the degree to which national literatures coevolved with new post-Persianate literary cosmopolitanisms and internationalisms.

This article theorises the repressive security practices of authoritarian states in the context of transnationalism and globalisation. While emerging research on transnational repression has identified a range of extraterritorial and exceptional security practices adopted by authoritarian states, it has not fully studied the implications of such practices on space and statecraft. Using data from the Central Asia Political Exile Database project (CAPE) and interviews conducted with exiled Tajik opposition groups based in Russia and Europe, we theorise the spatial connections between the territorial and extraterritorial security practices using the concept of assemblages. We further outline how these practices escalate in a three-stage model, in which exiles go on notice, are detained and then rendered or assassinated. Such an approach sheds light on the inherent links between the normalisation of security practices and the creation of transnational space with distinct forms of geographical state power that is embedded in non-national spaces and is manifested through spatially organised actors, networks, and technologies within assemblages.

Russia remains the destination of choice for Tajik migrants. Its migration policies have profound implications for migrants’ legal status and capacity to remit and return home. This article draws on ethnographic research in Dushanbe, Tajikistan, and explores how the enforcement of Russia’s immigration laws affects Tajik migrants and their families. By 2016, over 300,000 Tajik migrants were issued entry bars (zapret na v’ezd) for three or more years for two or more administrative offenses, including the lack of a work permit or a residential registration and a traffic violation. Migration and the transnational lifestyle increase agency among Tajik men and women, informing gender transformations. Entry bars produce temporary constraints to spatial and social mobility as migrants readjust to well-defined gender roles in their home country. We note how immigration laws affect men and women in different ways, contextualizing the gendered effects of entry bars through the lens of gender relations and understandings of masculinity and femininity in Tajikistan. We argue that the constraints to migrants’ mobility developed by Russian migration policies inform the reconstitution of gender relations in Tajikistan.

There is critical need for more information on the status of forests in Central Asia, to inform conservation management. Here we assess the status and use of the globally important, threatened walnut–fruit forests of Dashtijum Nature Reserve, Tajikistan. We use a mixed methods approach combining a semi-structured interview based socio-economic survey with statistical analysis. Thirty-three tree species were recorded, with Rosaceae the most common family. The mean basal area of the forest was 20.8 m2 per ha and most tree species exhibited stable population structures. Resource use was prevalent throughout the community; most households harvested at least one fruit or nut species (78%), firewood (88%) and grazed livestock (85%). Most respondents noted declines in availability of fruits, nuts and firewood and reported a decrease in the overall area and quality of grazing. Statistical analysis and machine learning identified that distance to nearest settlement significantly affected forest total basal area, tree species richness and the Shannon index, a metric of diversity sensitive to rare species. Our results suggest that conservation management by the government and NGOs is partly effective but there is a need for increased enforcement of grazing restrictions, to prevent further forest degradation.

This article reconsiders the religio-ritualistic interpretations of the use of the rhyton within eighth-century CE Sogdiana. Through a close art-historical analysis, it argues that three eighth-century wall paintings from Panjikent illustrate a drinking game. This proposal expands the current breadth of meaning attributed to the imagery decorating Sogdian homes. Not only could the paintings illustrate epic narratives, religious veneration, or moral didacticism, but they could also celebrate conviviality, fun, and humor.

Street food is part of the culture in central Asia. Although nourishing food can be found, unhealthier options are becoming increasingly popular – a marker of nutrition transition. The nutritional composition of street food in urban settings is, however, unknown. The objective of the present study was, thus, to characterise the street food availability in Dushanbe, Tajikistan. A total of 800 street food vending sites in public markets were selected through random and systematic procedures. Trained interviewers collected data on vending sites’ characteristics, location and food available. Samples of the most commonly available food were collected (ninety-nine homemade and thirty-five industrial). Macronutrients were quantified through proximate analysis. Fruit, drinks and food other than fruits were available, respectively, in 4·5, 40·5 and 87·4 %, of the vending sites. Among the latter, 63·6 % sold only homemade (e.g. bread, traditional dishes, snacks, pastries, sandwiches and cakes), 19·3 % only industrial (e.g. bread, snacks, pastries and cookies) and 17·1 % both types of food. Homemade food presented higher energy per serving compared with industrial food (median 452 v. 276 kcal/serving (1891 v. 1155 kJ/serving); P < 0·001). A high content of SFA (soup: 10·9 g/serving) and trans-fatty acids (cakes: 1·8 g/serving) was also found in homemade food. However, industrial wafers showed the highest content of these fatty acids (12·9 g/serving and 2·5 g/serving, respectively). Soft drinks were available in 68·5 % of the vending sites selling beverages. Homemade and industrial street food, with heterogeneous nutritional value, were widely available in Dushanbe. Hence, policies promoting the availability of healthy food should be encouraged.

The crystal structure of mendeleevite-(Ce), (Cs,☐)6(☐,Cs)6(☐,K)6(REE,Ca,☐)6(Si70O175) (H2O,OH,F,D)35, a new mineral from the moraine of the Darai-Pioz glacier, the Alai mountain ridge. Tien-Shan mountains, northern Tajikistan, was solved by direct methods and refined to Ri = 4.15% based on 2274 observed [Fo > 4σ|F|] unique reflections measured with Mo-Kα. radiation on a Bruker PA diffractorneter equipped with a CCD detector. Mendeleevite-(Ce) is cubic, space group Pm3̄, a 21.9148(4) Å, V 10525(1) Å3, Z = 2, Dcalc = 3.066 g/cm3. The empirical formula (electron microprobe) is CS5.94K2.22[(Ce11.35La5.86Nd3.23Pr1.54Sm0.32Gd0.20)Σ22.50(Ca4.68Sr1.00)Σ5.68]Σ28.18 Si70.12O203.17H45.67F6.83, Z = 2, calculated on the basis of 210 (O + F) a.p.f.u., with H2O and OH calculated from structure refinement (OH + F = 17 p.f.u.; H2O = 17.75 p.f.u.).

The structural formula is (Cs4.65☐1.35)Σ6(☐4.71Cs1.29)Σ6(☐3.78K2.22)Σ6﹛[(Ce11.35La5.86Nd3.23 Pr1.54Sm0.32Gd0.20)Σ22.50(Ca4.68Sr1.00)Σ5.68]Σ28.18☐1.82﹜Σ30(Si70O175)[(OH)10.17F6.83]Σ17(H2O)17.75. Simplified and endmember formulae are as follows: (Cs,☐)6(☐,Cs)6(☐,K)6(REE,Ca,☐)30(Si70O175) (H2O,OH,F,☐)35 and Cs6(REE22Ca6)(Si70O175)(OH,F)14(H20)21. The crystal structure of mendeleevite-(Ce) is an intercalation of two independent Si—O radicals and an M framework of (REE,Ca) polyhedra. The Si—O radicals are an (Si140O260)104– framework and an (Si36O90)36– cluster which do not link directly. The M framework is located between the Si—O framework and the Si—O clusters. Interstitial cations occupy two types of cages and channels. Cages I and II are 78 and 22% occupied by Cs. Channels along [100↻] contain K atoms and H2O groups. Mendeleevite-(Ce) has no natural or synthetic structural analogues. Mendeleevite-(Ce) is a framework mineral with large cavities and it has the potential to be used as a model for the synthesis of microporous materials of industrial interest.

Hyalotekite, a framework silicate of composition (Ba,Pb,K)4(Ca,Y)2Si8(B,Be)2 (Si,B)28F, is found in relatively high-temperature (⩾ 500°C) Mn skarns at Långban, Sweden, and peralkaline pegmatites at Dara-i-Pioz, Tajikistan. A new paragenesis at Dara-i-Pioz is pegmatite consisting of the Ba borosilicates leucosphenite and tienshanite, as well as caesium kupletskite, aegirine, pyrochlore, microcline and quartz. Hyalotekite has been partially replaced by barylite and danburite. This hyalotekite contains 1.29–1.78 wt.% Y2O3, equivalent to 0.172–0.238 Y pfu or 8–11% Y on the Ca site; its Pb/(Pb+Ba) ratio ranges 0.36–0.44. Electron microprobe F contents of Långban and Dara-i-Pioz hyalotekite range 1.04–1.45 wt.%, consistent with full occupancy of the F site. A new refinement of the structure factor data used in the original structural determination of a Långban hyalotekite resulted in a structural formula, (Pbl.96Bal.86K0.18)Ca2(B1.76Be0.24)(Sil.56B0.44)Si8O28F, consistent with chemical data and all cations with positive-definite thermal parameters, although with a slight excess of positive charge (+57.14 as opposed to the ideal +57.00). An unusual feature of the hyalotekite framework is that 4 of 28 oxygens are non-bridging; by merging these 4 oxygens into two, the framework topology of scapolite is obtained. The triclinic symmetry of hyalotekite observed at room temperature is obtained from a hypothetical tetragonal parent structure via a sequence of displacive phase transitions. Some of these transitions are associated with cation ordering, either Pb–Ba ordering in the large cation sites, or B–Be and Si–B ordering on tetrahedral sites. Others are largely displacive but affect the coordination of the large cations (Pb, Ba, K, Ca). High-resolution electron microscopy suggests that the undulatory extinction characteristic of hyalotekite is due to a fine mosaic microstructure. This suggests that at least one of these transitions occurs in nature during cooling, and that it is first order with a large volume change. A diffuse superstructure observed by electron diffraction implies the existence of a further stage of short-range cation ordering which probably involves both (Pb,K)–Ba and (BeSi,BB)–BSi.
