Krishna Kumar on reading
No full textKrishna Kumar (1986) begins by defining what
reading is. He espouses exposure to books even
before children can decipher the alphabet.
According to him, unless a child makes sense
of what he/she reads, and relates it to something
else, one cannot call it reading. He defines
reading as “a process of finding meaning in
written words” (Kumar: 1986)

No full textAsystasia venui Anant Kumar, G. Krishna & Av. Bhattacharjee sp. nov. FIGURES 2 & 3 Type:— INDIA. West Bengal, Howrah, Acharya Jagdish Chandra Bose Indian Botanic Garden, along bank of Janardanam Lake, 11.3 m, 22.55856° E & 88.29227° N, 20.11.2019, Anant Kumar, Gopal Krishna & Avishek Bhattacharjee 86184 (Holotype CAL, CAL0000033886; isotype CAL, CAL0000033887!). Diagnosis:— Asystasia venui is morphologically allied to A. atroviridis Anderson (1867: 526), but differs in having smaller calyx lobes (vs. longer calyx lobes); papillose ovary (vs. glandular hairy ovary); glabrous style throughout (vs. style pubescent basally); densely glandular pubescent capsules (vs. glabrous capsules).

Leaves opposite, decussate, petiolate or uppermost pair sessile; petioles (0−) 0.5−8 cm long, sulcate, pubescent; lamina elliptic-ovate to elliptic-lanceolate, uppermost pair ovate to broadly ovate, smaller in size, 1.4−10 × 0.9−4.4 cm, chartaceous, base unequal, rounded, subcordate, attenuate, or decurrent onto petiole when young, margin entire, apex shortly acuminate, pubescent and green above, tuberculate, glabrous and whitish beneath, veins camptodromous, midvein prominent, impressed above, prominent below, pubescent, lateral veins 5−7 pairs, otherwise same as mid vein. Inflorescences terminal, condensed racemes, 1–4 cm long, 4−12-flowered, pubescent. Flowers ca. 2 cm across; pedicels slender, 1−1.2 cm long, pubescent. Bracts triangular, 1.2–1.5 mm long, apex acuminate, margin ciliate persistent; bracteoles ovate-lanceolate, 0.5–0.7 mm long, apex acute, margin ciliate, persistent. Calyx 5-lobed, pubescent and glandular-hairy outside, glabrous inside; tube 1–1.5 mm long; lobes linear-lanceolate, 3−3.5 mm long, apex acute. Corolla infundibuliform, ventricose, white, with a light violet-purple blotch on the middle lobe of lower lip, glandular-hairy outside, glabrous inside; tube 2–2.3 cm long, base cylindrical for 1.5–1.7 cm long, throat 5–6 mm long; lobes 5, elliptic-ovate, 5−7 × 4–4.5 mm, apex obtuse. Stamens 4, didynamous, inserted at base of throat, slightly exserted; filaments white, slender, shorter pair 5−5.5 mm long, longer pair 8−8.5 mm long, connate at the base in pairs, glabrous; anthers white with a vertical violet-black band on the sides, oblong, 1.2–1.5 cm long, spurred at base, connective beyond the anther cells, glabrous. Ovary green, oblong or columnar, compressed, 1.2−1.5 mm long, papillose, basally surrounded by fleshy, dull white, nectariferous disc, 2-celled; ovules 2 in each cell; style white, filiform, 2.4–2.6 cm long, glabrous; stigma shortly 2-lobed, smooth. Capsules green, clavate, compressed, 1.4–2.2 cm long, dehiscent, densely glandular hairy. Seeds 4, suborbicular, flattened, ca. 3 mm across, tuberculate, rugose, dentate along margins, borne on ca. 2 mm long, hook-like retinacula. Phenology:—Flowering and fruiting from September to December. Habitat: — The new species grows along lakes in shady area at an elevation of about 10 m. The association includes Rivina humilis L., Ruellia tuberosa L., Cardiospermum halicacabum L., Mikania micrantha Kunth and Plumbago zeylanica L. and grasses etc. Distribution:—The species is distributed in Howrah, West Bengal, India so far. Etymology:—The new species is named after Dr Potharaju Venu, Former Senior Scientist of Botanical Survey of India, for his significant contribution to the taxonomy of Indian Acanthaceae. Notes:— The Indian species of the genus can be categorized in two groups on the basis of shape of corolla tube, i.e. Group 1 comprises three species Asystasia atroviridis Anderson (1867: 526), A. neesiana (Wallich 1830: 73) Nees (1832: 89), A. venui Anant Kumar, G. Krishna & Av. Bhattacharjee sp. nov. having cylindrical, shortly funnelshaped corolla tube upwards, and Group 2 having 10 species A. chelonoides Nees (1832: 89), A. crispata Bentham (1852: 647), A. dalzelliana Santapau (1948: 276), A. gangetica (Linnaeus 1756: 3) Anderson (1860: 235), A. indica H.J. Chowdhery & Av. Bhattacharjee (2006: 211), A. macrocarpa Nees (1832: 89), A. mysorensis (Roth 1821: 303) Anderson (1867: 524), A. pusilla C.B. Clarke (1889: 55), A. travancorica Beddome (1872: 39), and A. variabilis (Nees 1847: 165) Trimen (1895: 324) with tubular-ventricose corolla tube (FIGURE 1). Out of these, five species are endemic to India, e.g., A. crispata, A. dalzelliana, A. indica, A. pusilla, and A. travancorica. Lindau (1895) erected a new genus Asystasiella Lindau (1895: 326) to accommodate the species of Group one with two species, viz. A. neesiana and A. atroviridis, and it was considered to be different from Asystasia by having a narrow cylindric corolla tube and stachel pollen (spheroidal with spines). Ensermu et al. (1992) discussed the delimitation of the genus based on pollen morphology. Since, the genus Asystasia encompasses considerable variation in inflorescence form, corolla morphology, and pollen type, therefore, the genus Asystasiella was included within Asystasia (Manzitto-Tripp et al. 2022). The generic circumscription of Asystasia, Asystasiella, Mackaya and other related genera should be delimitated by molecular phylogenetic study along with pollen morphology. Das (1939: 408) incorrectly transferred these three species from Asystasia to Mackaya as M. atroviridis (Anderson 1867: 526) Das (1939: 448), M. macrocarpa (Nees 1832: 89) Das (1939: 447), and M. neesiana (Wallich 1830: 73) Das (1939: 447), respectively. However, the genus Mackaya is characterized by two fertile stamens without spurs and with two staminodes, while Asystasia has all four fertile stamens with spur at the base of anthers. Deng and Wu (2009: 308) stated that these three species were quite different from Mackaya in having four stamens and they preferred to place them in Asystasia rather than in Mackaya. Based on the above mentioned reasons the new species fits with Asystasia instead of Mackaya and hence, we are describing it here under Asystasia. The new species was wrongly identified as Asystasia chelonoides Nees by Chowdhery and Pandey (2007). However, it can be easily distinguished from Asystasia chelonoides by its long tubular-cylindrical corolla and densely flowered racemes. Comparison of diagnostic characters of the new species with its most allied species is provided in detail in Table 1. Additional specimens examined (Paratypes):— INDIA.

Entry Costs, Intermediation, and Capital Flows
No full textIn this paper, we reexamine the question "Why doesn't capital flow from rich to poor countries?" posed, most recently, by Lucas (1990). We build a simple contracting framework where costly intermediation together with an adverse selection problem have quantitatively important effects on capital flows. When intermediation costs are ignored, the model behaves much like the neoclassical model in terms of capital returns. However, when intermediation costs are considered, the return for a given amount of capital can be non-monotonic in costs. Therefore, the combination of capital and cost differences across countries gives rise to a rich variation of returns, one that suggests a tendency for capital to flow to middle income countries, as seen in data. Indeed, when we embed the static return function in a two-country dynamic model, there is capital outflow from a poor country that removes capital controls and becomes open. We find that even though the closed economy dominates in terms of capital employed in production, it is the open economy that dominates in terms of income, consumption and welfare.Capital flows, Financial intermediation

An Analysis of Career Growth Opportunities in Commerce Stream by Introduction of NEP 2020
No full text<p><em> An important turning point in India’s educational landscape can be seen with the National Education Policy (NEP) 2020. NEP 2020 has a number of goals, one of which is to revolutionise the commerce stream by providing students with a wide range of opportunities for career advancement. The National Education Policy (NEP) 2020 marks the beginning of a paradigm shift in the Indian education system, aimed at providing inclusive and flexible learning opportunities. One of the key aspects of NEP 2020 is its emphasis on interdisciplinary education and the promotion of diverse career paths beyond traditional academic fields. This study aims to analyze the impact of NEP 2020 on career advancement opportunities in the field of commerce.</em></p>
