Chemistry research in India in a global perspective : a scientometrics profile

We measure India’s contribution to chemistry research in a global perspective. In the five years 2011-2015 Indian researchers have published 62,448 papers in 557 journals. In terms of % share, India (with 6.9% of the world’s publications) is behind only China (25%) and USA (17%). But only 0.86% of papers from India are among the top 1% of the most highly cited papers of the world, compared to 4.86% of papers from Singapore, 2.65% of papers from USA, 2.09% of papers from China, 1.87% of papers from the UK, 1.71% of papers from South Korea and 1.6% of papers from Germany. Papers from India are cited 14.68 times on average compared to cites per paper of 45.34 for Singapore, 30.47 for USA, 23.12 for China, 26.51 for the UK, 21.77 for South Korea and 24.77 for Germany. Less than 39% of papers from India are found in quartile 1 (high impact factor) journals, compared to 53.6% for China and 53.8% for South Korea. Percent share of papers in quartile 1 journals from India is lower than that for the world for all of chemistry and for each one of the eight categories, viz. analytical, applied, inorganic & nuclear, medicinal, multidisciplinary, organic, physical and electrochemistry whether one considers data for the entire five-year period or for 2015 alone. About 20% of Indian chemistry papers are in collaboration with international coauthors. Researchers from only 160 Indian institutions have published at least 100 papers (compared to 362 in USA and 399 in China) and these include 67 state, 14 central and 11 private universities, 27 institutions under the Ministry of Human Resource Development, 20 CSIR laboratories, seven Department of Atomic Energy institutions, and seven Department of Science & Technology institutions. About 40% of all Indian chemistry papers have come from public universities. Only three Indian institutions, viz Bhabha Atomic Research Centre, Indian Institute of Science and Indian Institute of Chemical Technology, have published more than 2,000 papers. None of the Indian universities has performed as well as leading Asian universities. Amrita Vishwa Vidyapeetham, a small institution with less than 200 papers, has performed reasonably well

The Maturing of E-Commerce Education in Our Curricula

When the power of e-commerce was unleashed for the benefit of the society, the evolution of the business world started. Businesses used electronic data interchange (EDI) to reduce costs, increase the speed, and increase the accuracy of business documents when doing business with other companies. Consumers were no longer tied to local stores or mail catalogues for retail purchases. E-commerce became a new retail outlet in the late 1990s. Educational institutions, for their part, responded by initiating e-commerce related research and curricula. Since those early days of e-commerce education, e-commerce education has matured. It has transformed from scattered courses and is now manifested in undergraduate and graduate degree programs

Managing project scope creep in construction industry

Purpose Project scope creep is a nightmare and nearly intolerable task. Most project managers struggle to curtail the expanse and degree of scope creep. This study examines different likely project scope creep factors associated with the construction industry projects. Design/methodology/approach After many brainstorming sessions with construction stakeholders, several project scope creep factors were identified. Then, a detailed survey was executed in big construction projects of the United Arab Emirates (UAE). The data were analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Findings The results derived and validated five conspicuous factors leading to project scope creep. Respectively, the highest and the lowest impact on project scope appears to be imposed by tasks/specifications and complexity/uncertainty. Practical implications It offers crucial support to the project stakeholders in scrutinizing different factors that stand as hurdles to project success and allows them to seek remedies to resolve them. Originality/value It is among the first study in the region that identifies and validates the factors that hinder construction project success.©2022 Emerald Publishing Limited.

Vibrio alginolytigus causing shell disease in the mud crab Scylla serrata (Forskal 1775)

1359-1363Scylla serrata is one of the most cultured mud crab species in the aquaculture which is also susceptible to shell disease. In the present study, Vibrio alginolyticus MF680287.1 caused by shell disease and isolated from infected mud crab S. serrata grow out pond located at Mahendrapalli, Nagapattinam District, Tamil Nadu, India. Further, gross observation of infected mud crab showed shell lesion on the dorsal carapace. The histological examination of normal and diseased mud crab S. serrata carapace and gills was conducted. The shell lesion affected in the S. serrata carapace layers showed loss of membrenous layer and epithilium. The bacterial colonies were abundant in the cuticle. The gill lamellae showed cuticlar damage in the formation of haemocyte nodules and eosinophilic granular cells

3-Benzoyl-1,1-dibenzyl­thio­urea

Two independent thio­urea mol­ecules comprise the asymmetric unit of the title compound, C22H20N2OS. The central N–C(=S)N(H)C(=O) atoms in each mol­ecule are virtually superimposable and each is twisted [C—N—C—S torsion angles = 121.3 (3) and −62.3 (4)°]. The mol­ecules differ only in terms of the relative orientations of the benzyl benzene rings [major difference between the C—N—C—C torsion angles of −146.6 (3) and −132.9 (3)°]. The presence of N—H⋯S hydrogen bonding leads to the formation of supra­molecular chains along the a axis. These are consolidated in the crystal packing by C—H⋯O inter­actions. The crystal was found to be a combined non-merohedral and racemic twin (twin law 00/00/001), with the fractional contribution of the minor components being approximately 9 and 28%

1-Benzoyl-3,3-dibutyl­thio­urea

The title mol­ecule, C16H24N2OS, is twisted about the central N(H)—C bond with a C—N(H)—C—N torsion angle of −62.67 (15)°. The carbonyl group is twisted out of the plane of the benzene ring, forming a C—C—C=O torsion angle of −25.06 (17)°. In the crystal, mol­ecules related by centres of symmetry are linked by pairs of inter­molecular N—H⋯S hydrogen bonds, forming eight-membered {⋯HNCS}2 synthons. These are further connected by weak via C—H⋯O contacts, forming a two-dimensional array in the bc plane

1-Benzoyl-3,3-bis­(propan-2-yl)thio­urea

Two independent thio­urea derivatives comprise the asymmetric unit of the title compound, C14H20N2OS. The major difference between the mol­ecules relates to a twist in the relative orientation of the benzene rings [torsion angles = 4.5 (2) and −19.9 (2)° for the two independent mol­ecules]. The thio­carbonyl and carbonyl groups lie to opposite sides of the mol­ecule as there are twists about the central N—S bond [torsion angles = 83.90 (15) and 81.77 (15)°]. Supra­molecular chains extending parallel to [101] with a stepped topology and mediated by N—H⋯O hydrogen bonding feature in the crystal structure. C—H⋯O and C—H⋯π inter­actions are also present

Social sustainability in the supply chain: Construct development and measurement validation

Research on social sustainability in developing countries has recently gained importance for both academics and practitioners. Studies in the supply chain management field take either a supplier or a manufacturer perspective that address predominantly corporate social responsibility (CSR) issues referring to the internal stakeholders. Our research integrates the literature on supplier, manufacturer, and customer responsibility and proposes the concept of supply chain social sustainability (SCSS) that refers to addressing social issues within the overall (upstream and downstream) supply chain. Furthermore, we develop and empirically validate scales for measuring SCSS using in-depth interviews and a survey in the Indian manufacturing industry. Our results suggest that SCSS consists of six underlying dimensions, namely equity, safety, health and welfare, philanthropy, ethics, human rights, in a 20-item valid and reliable scale. We discuss the implications of the findings for research and practice and suggest future research avenues
