Dr. Monti Datta – Faculty Author Interview
No full textDr. Monti Datta, Assistant Professor of Political Science, discusses his forthcoming new book, Anti-Americanism and the Rise of World Opinion. Drawing from a wealth of research data, interviews and surveys of social media, this book directly examines pro- and anti-American views and asks what we can learn about the nature and impact of world opinion. By treating anti-Americanism as a case study of public opinion at work, Professor Datta reveals how we can better understand the relationship between global citizens and their political leaders, and concludes that anti-Americanism does in fact substantially impact US security, as well as its economic and political interests
Tapping Economies of Scale and Scope in Consumer Cooperation - A Case Analysis of Possible Cooperation among selected Cooperatives
No full textBecause of its narrow and negative perspective of safeguarding the interests of only poor consumers against unethical practices of the private traders, consumer cooperation in India seems to have failed, except probably in some isolated pockets. A number of social welfare functions like poverty alleviation and public distribution of essential items of consumption have been imposed on them at the cost of their basic economics. With the basic micro and macro-economic rationale for consumer cooperatives as a positive form of economic organization being lost sight of, they seem to be facing enormous problems both historically as well as currently in a era of economic liberalization. Their worries seem to have been compounded with the threat of impending competition from large private enterpriss - both domestic and foreign, which highlights the need for evolving strategies to rectivy their systemic weaknesses and tackling the competition head on. This case has attempted to document just such an initiative through a round table conference with several doyens of the consumer cooperative movement in India such as Warana Bazar and Amalsad Mandali as well as some fledging consumer cooperatives from West Bengal which are already in existence for some time or contemplating entry into this field. The roundtable conference organized in the spirit of Cooperation among Cooperatives attempted to evolve strategies to capture economies of scale and scope in order to take on the competition, as well as to facilitate dissemination of ideas and information across the country.

This taxon was treated as a junior synonym of Cyana subornata (Walker, 1854) distributed in Sri Lanka (Hampson 1900; Draudt 1914; Strand 1922). However, significant external and genital differences prove its species status. 2. In the original description, Swinhoe (1891) did not mention a number of specimens, but cited two localities therefore the existence of syntypes is obvious. In order to stabilize the nomenclature, we designate the specimen deposited in NHMUK and labeled as ‘type’ as lectotype. Diagnosis. Forewing length is 13–13.5 mm in males and 15–16 mm in females. Cyana linatula is a closest relative of C. subornata (Figs 28, 29), but can be easily distinguished by its inner black edging of the antemedial line and outer black edging of the postmedial line, whereas in C. subornata both lines are pure red. The male genitalia of C. linatula differ from those of C. subornata (Fig. 174) by the larger ventral subbasal diverticulum, the larger dorsal medial diverticulum, and the presence of a cluster of small spinules on the tip of the distal diverticulum. The female genitalia of C. linatula differ from those of C. subornata (Fig. 247) by their broader ostium bursae, more strongly rugose posterior section of corpus bursae, and more robust spinulose scobination of the appendix bursae. Distribution. India (Rajasthan, Meghalaya, Maharashtra, Tamil Nadu, Karnataka, Kerala) (Singh et al. 2014, as C. subornata). The record for the Andaman Islands (Swinhoe 1891) belongs to C. rudloffi.Published as part of Singh, Navneet, Volynkin, Anton V., Kirti, Jagbir Singh, Datta, Harvinder Singh & Ivanova, Maria S., 2020, A review of the genus Cyana Walker, 1854 from India, with descriptions of five new species and three new subspecies (Lepidoptera: Erebidae: Arctiinae: Lithosiini), pp. 1-93 in Zootaxa 4738 (1) on page 15, DOI: 10.11646/zootaxa.4738.1.1, http://zenodo.org/record/367243
Lattice study of a magnetic contribution to heavy quark momentum diffusion
No full textHeavy quarks placed within a hot QCD medium undergo Brownian motion, characterized by specific transport coefficients. Their determination can be simplified by expanding them in T/M, where T is the temperature and M is a heavy quark mass. The leading term in the expansion originates from the colour-electric part of a Lorentz force, whereas the next-to-leading order involves the colour-magnetic part. We measure a colour-magnetic 2-point correlator in quenched QCD at T ∼ (1.2 − 2.0)Tc. Employing multilevel techniques and non-perturbative renormalization, a good signal is obtained, and its continuum extrapolation can be estimated. Modelling the shape of the corresponding spectral function, we subsequently extract the momentum diffusion coefficient, κ. For charm (bottom) quarks, the magnetic contribution adds ∼ 30% (10%) to the electric one. The same increases apply also to the drag coefficient, η. As an aside, the colour-magnetic spectral function is computed at NLO

The replacement name is dedicated to G.S. Arora, author of the basic publication on the fauna of the Andaman and Nicobar Islands. Remark. The taxon tripunctata Reich, 1935 was described under the genus Lyclene. Here we transfer it to the genus Cyana and synonymize with C. detrita (see above). Thus, at present there are two Cyana taxa with the name tripunctata, so tripunctata Rothschild, 1936 becomes a junior secondary homonym of tripunctata Reich, 1935. Hence, we introduce the replacement name arorai nom. nov. for tripunctata Rothschild, 1936. Diagnosis. Forewing length is 12.5–15 mm in males and 17–18 mm in females. Cyana arorai is a polymorphic species, significantly variable in size. Cyana arorai is similar externally to C. carmina (Figs 13, 14), but differs by its arcuate antemedial line (that is oblique in C. carmina) and larger black discal spots. In females of C. arorai a third, posterior black spot may be developed (Figs 16, 17), what is unusual for the C. insularis group. The female genitalia of C. arorai are very similar to those of C. carmina (Figs 239, 240), but differ by the more heavily sclerotized cervix bursae having narrower longitudinal folds, and the lateral band-like signum being more weakly sclerotized subanteriorly with its anterior end strongly broadened. Distribution. Endemic of the Andaman Islands. The records of C. bianca (male) and C. coccinea (female) for the Andaman Islands (Hampson 1900; Draudt 1914; Arora 1983) belong to C. arorai.Published as part of Singh, Navneet, Volynkin, Anton V., Kirti, Jagbir Singh, Datta, Harvinder Singh & Ivanova, Maria S., 2020, A review of the genus Cyana Walker, 1854 from India, with descriptions of five new species and three new subspecies (Lepidoptera: Erebidae: Arctiinae: Lithosiini), pp. 1-93 in Zootaxa 4738 (1) on page 10, DOI: 10.11646/zootaxa.4738.1.1, http://zenodo.org/record/367243

Morphologically, Miltochrista jarawa, sp. nov. (Figs 1–3) is similar to M. lutara (Figs 4–9), but is distinguishable externally by its smaller size, the less sinuous antemedial line, the irregularly sinuous medial line interrupted on the vein R (that is continuous and smoothly arcuate in M. lutara), and the less zigzagged postmedial line. The male genital capsule of the new species (Figs 10, 11) is closely similar to that of M. lutara (Figs 12, 13), but differs by the more elongate valva with the more elongate and broader distal lobe, the straight dorsal margin of sacculus (in M. lutara, that bears a broad but short triangular protrusion medially), and the slightly curved distal saccular process (in M. lutara, the saccular process is conspicuously more sinuate). The vesica of M. jarawa sp. nov. is much broader than that of M. lutara, the subbasal diverticulum is broader, the distal diverticulum is much broader, and the cornutus is conspicuously longer and more robust in comparison with those structures of M. lutara. The female genitalia of the new species (Fig. 14) differ from those of M. lutara (Fig. 15) by the slightly shorter apophyses posteriores, the conspicuously shorter apophyses anteriores having rounded tips (those are apically pointed in M. lutara), the sclerotized anterior section of the ductus bursae (that is membranous in M. lutara), the broader sclerotized band of the posterior section of the corpus bursae bearing smaller denticles anteriorly, the larger right lateral protrusion of the corpus bursae, the broader anterior section of the corpus bursae with a longer area of a larger spinulose scobination having a triangular medial posterior extension (that is absent in M. lutara), and the slightly broader appendix bursae. Description. External morphology of adults . Male (Figs 1, 2). Forewing length 7.5–8 mm. Antenna ciliate. Head and thorax maize yellow. Anterior half of abdomen maize yellow, posterior half of abdomen blackish. Forewing with ground color maize yellow; costa curved opposite distal end of cell; patterning blackish; subbasal spot large, circular; subbasal area with two spots along a convex, slightly wavy antemedial line; medial line strongly sinuous medially and posteriorly, disappearing anteriorly and represented by a dot on vein R; postmedial line strongly and irregularly dentate; subterminal line represented by a series of large, variously sized spots on veins; terminal line absent; cilia concolourous with ground color. Hindwing pale yellowish, with blackish suffusion at apex. Female (Fig. 3). Forewing length 8–8.5 mm. Antenna filiform. Forewing with ground color maize yellow, pattern blackish; subbasal spot circular; subbasal area with two large spots along the convex, slightly wavy antemedial line; medial line strongly sinuous; postmedial line irregularly dentate; subterminal line represented by a series of large, various sized spots on veins; terminal line absent; cilia as ground color. Hindwing pale yellowish, with blackish suffusion at apex. Male genitalia (Figs 10, 11): Uncus narrow and elongate, slightly curved, narrowed distally and apically pointed; tuba analis moderately broad, scaphium thin and weakly sclerotized; tegumen moderately short and narrow; vinculum short, broadly v-shaped with rounded tip; juxta weakly sclerotised, trapezoid. Valva elongate, narrow, slightly curved; costa narrow, ending at end of distal lobe and lacking any processes; sacculus long and narrow, its distal process narrow, slightly curved dorsally, pointed apically; aedeagus cylindrical, with short and slightly broadened coecum; vesica with short but broad subbasal ventral diverticulum, granulated outer surface of the medial section, with large bilobate and granulate distal diverticulum and robust, blade shape distal cornutus on a narrow and elongate base. Female genitalia (Fig. 14). Papilla analis broadly rectangular with round corners, weakly setosed; apophyses elon-gate and thin, apophyses posteriores slightly narrower than apophyses anteriores; ostium bursae narrow, with membra-nous margins; ductus bursae tubular and relatively narrow, its posterior half membranous; anterior half of ductus bursae and posterior end of corpus bursae with rugose sclerotization; posterior section of corpus bursae dilated, thick-walled, with broad semiglobular lateral protrusion on its right side and short posterior protrusion on its left side; medial part of posterior section of corpus bursae bearing long, narrow, strongly curved and heavily sclerotized band covered with numerous short but robust spines; anterior section of corpus bursae sac-like, densely covered in numerous spinules on broad bases, this area of scobination protruding to medial part of corpus bursae; appendix bursae short but broad, thick-walled, situated on left side of posterior section of corpus bursae. Distribution. The new species is known from the Andaman Islands only. Etymology. The Jarawa people are a nation living in Middle and South Andaman Islands. The specific name is a noun in nominative case.Published as part of Singh, Navneet, Volynkin, Anton V., Kirti, Jagbir Singh & Datta, Harvinder Singh, 2020, Miltochrista jarawa (Lepidoptera, Erebidae, Arctiinae, Lithosiini), a new species from the Andaman Islands, India, pp. 445-450 in Zootaxa 4895 (3) on pages 446-447, DOI: 10.11646/zootaxa.4895.3.10, http://zenodo.org/record/432669
