Vol: Ii (1938) of “Flora of Assam”
Plant Archives Vol. 14 No. 1, 2014 pp. 87-96 ISSN 0972-5210 AN UPDATED ACCOUNT OF THE NAME CHANGES OF THE DICOTYLEDONOUS PLANT SPECIES INCLUDED IN THE VOL: I (1934- 36) & VOL: II (1938) OF “FLORA OF ASSAM” Rajib Lochan Borah Department of Botany, D.H.S.K. College, Dibrugarh - 786 001 (Assam), India. E-mail: [email protected] Abstract Changes in botanical names of flowering plants are an issue which comes up from time to time. While there are valid scientific reasons for such changes, it also creates some difficulties to the floristic workers in the preparation of a new flora. Further, all the important monumental floras of the world have most of the plants included in their old names, which are now regarded as synonyms. In north east India, “Flora of Assam” is an important flora as it includes result of pioneering floristic work on Angiosperms & Gymnosperms in the region. But, in the study of this flora, the same problems of name changes appear before the new researchers. Therefore, an attempt is made here to prepare an updated account of the new names against their old counterpts of the plants included in the first two volumes of the flora, on the basis of recent standard taxonomic literatures. In this, the unresolved & controversial names are not touched & only the confirmed ones are taken into account. In the process new names of 470 (four hundred & seventy) dicotyledonous plant species included in the concerned flora are found out. Key words : Name changes, Flora of Assam, Dicotyledonus plants, floristic works. -

Jagdish Chandra Bose and Plant Neurobiology: Part I
Indian Journal of History of Science, 54.2 (2019) 173-188 DOI: 10.16943/ijhs/2019/v54i2/49660 Jagdish Chandra Bose and Plant Neurobiology: Part I Prakash N Tandon* (Received 23 January 2019) Abstract Sir Jagdish Chandra Bose, a renowned physicist of Kolkata (Calcutta), in the early years of the twentieth century, progressively turned his attention to plant physiology. Utilizing some self-devised equipment he described the existence of nervous system in all varieties of plants. Recent years have seen a renewed interest in this field. Acknowledging Sir Bose’s pioneering work, a new discipline of physiology—Plant Neurobiology has been revived. The paper provides a historical account of this work.

Economics Working Papers on Self Selection of the Corrupt Into the Public Sector
Wor King Papers Economics Working Papers 2015-01 On Self Selection of the Corrupt into the Public Sector Ritwik Banerjee, Tushi Baul, and Tanya Rosenblat On Self Selection of the Corrupt into the Public Sector Ritwik Banerjee∗1, Tushi Baul2, and Tanya Rosenblat3 1Department of Economics and Business, Aarhus University 2Department of Economics, New York University, Abu Dhabi 3School of Information, University of Michigan, USA Abstract Do corrupt people self select themselves in professions where the scope of corruption is high? We conduct a corruption experiment with private sector job aspirants and aspirants of Indian bureaucracy. The game models embezzlement of resources in which “supervisors” evaluate the performance of “workers” and then pay them. We find that aspirant bureaucrats indulge in more corruption than private sector aspirants but the likelihood of being corrupt is same across two sectors. JEL Classification: C91 D73 O12 K42 Keywords: Corruption, Experiments, Bureaucracy 1 Introduction The rich literature on labor market sorting indicates that the dimensions of sorting are indeed numerous - more productive firms employ more productive employees (Abowd et al., 1999), gregarious workers flock towards jobs with higher social interaction (Krueger and Schkade, 2007) and better economic incentives attract better quality (more honest) politicians in Brazil (Ferraz and Finan, 2011). In this paper, we use an experimental corruption game to study if corruption is a potential dimension of sorting. Past studies examining efficacy of food, health, education and employment guarantee programs in developing countries, suggest that enormous amount of public resources end up being embezzled1. Despite this and the fact that embezzlement of public resource causes more loss to welfare than petty corruption (Shleifer and Vishny, 1993), the literature on experimental corruption games has largely focused on petty bribery. -
Searching for the Greatest Bengali: the BBC and Shifting Identity
National Identities Vol. 10, No. 2, June 2008, 149Á165 Searching for the greatest Bengali: The BBC and shifting identity categories in South Asia Reece Jones* University of Wisconsin-Madison, USA Drawing on debates generated by the BBC Bengali Language Service’s naming of the greatest Bengali of all time, this article investigates the shifting boundaries between group identity categories in our ‘globalising’ world. First, the con- troversy over the meaning of the term ‘Bengali’, which emerged in contemporary Bangladesh and India in response to the BBC’s list, is investigated. Then writings and speeches of several of the individuals who were honoured as the greatest Bengalis are analysed in order to draw out the multiple ways they approached their own Bengali identities. In the conclusion, it is argued that rather than imagining the end of place-based identity categories through the process of globalisation, it is more useful to conceptualise shifting categories that continue Downloaded By: [Jones, Reece] At: 15:14 29 April 2008 to incorporate a place-based aspect, but in hybrid and contradictory ways. Keywords: categories; ethnicity; nations; globalisation; South Asia In Spring 2004, following the British Broadcasting Company’s naming of Winston Churchill as the greatest Briton of all time, the BBC Bengali Language Service conducted a survey of its twelve million listeners to determine the greatest Bengali of all time (BBC, 2004).1 Respondents were asked to rank their top five choices and in the end more than 100 individuals received votes. The top twenty were announced one per day beginning on 26 March, Bangladesh’s Independence Day, and ending on 15 April, the Bengali New Year’s Day, with the naming of Sheikh Mujibur Rahman as the greatest Bengali of all time. -

Tagore's School and Methodology: Classrooms Without Walls
2016 | GITANJALI & BEYOND 1: 83-101 Tagore's School and Methodology: Classrooms Without Walls Thomas B. KANE, Edinburgh Napier University Abstract: This paper argues that Rabindranath Tagore, a very practical man, devel- oped a distinctive and successful educational methodology over the course of his work in educational systems. The paper seeks to show that Tagore drew inspiration and direction from extraordinary times, and ex- traordinary people of those times. The paper establishes the Tagore fami- ly’s place within the ongoing Bengali Renaissance; and to Tagore’s place among remarkable individuals, particularly Jagadish Chandra Bose and Patrick Geddes. The paper looks to the emergence of the poet’s education- al institutions from spiritual and technological viewpoints. An attempt is made to show that Tagore’s educational establishments were methodolog- ically developed, can claim to be part of his poetic legacy; and that telepresence technologies of the twenty-first century might offer good service to those establishments as they continue to evolve.

KANE Tagore’s educational achievements gain perspective when viewed as a consequence of the Bengali Renaissance, which the Tagore family contrib- uted to for three generations. A major aspect of the Bengali renaissance was spiritual: specifically, reconnection with the ancient Vedic and Upani- shadic scriptures. The 32 years, spanning Tagore's life from 30 to 62, saw Tagore integrate his poetic and spiritual sensibilities with an evolving edu- cational methodology. -

The Saptarsis or the seven Sages represent a primordial cosmic consortium of ancient Vedic India. They are the forerunners of all Indian Knowledge systems. To name a few, the genesis of w Cosmology, astral and positional astronomy (Jyotir tatha Mahajagatik Vidya) was forwarded by the lineage of Maharshi Bhrigu, and Maharshi Vasistha-Sakti-Parashar. It is also the foundation of mathematics (bijaganita) and geometry (jyamatra) that originated in ancient India; w Health Sciences (Ayurveda) goes to Maharshi Bharadwaj; w Earth, terrestrial and built-environmental sciences (Vasu and Vaastu Vidya) belong to Maharshi Vasistha and other associated Sages.
