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
Get PDFBecause 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.
Excitation of the Brain Stem Pedunculopontine Tegmentum Cholinergic Cells Induces Wakefulness and REM Sleep
No full text Datta, Subimal and Donald F. Siwek. Excitation of the brain stem pedunculopontine tegmentum cholinergic cells induces wakefulness and REM sleep. J. Neurophysiol. 77: 2975–2988, 1997. Considerable evidence suggests that brain stem pedunculopontine tegmentum (PPT) cholinergic cells are critically involved in the normal regulation of wakefulness and rapid eye movement (REM) sleep. However, much of this evidence comes from indirect studies. Thus, although involvement of PPT cholinergic neurons has been suggested by numerous investigations, the excitation of PPT cholinergic neurons causal to the behavioral state of wakefulness and REM sleep has never been directly demonstrated. In the present study we examined the effects of three different levels of activation of PPT cholinergic cells in wakefulness and sleep behavior. The effects of glutamate on the activity of PPT cholinergic cells were studied by microinjection of one of the three different doses of l-glutamate (0.3, 1.0, and 3.0 μg) or saline (vehicle control) into the PPT cholinergic cell compartment while quantifying the effects on wakefulness and sleep in free moving chronically instrumented cats. All microinjections were made during wakefulness and were followed by 4 h of recording. Polygraphic records were scored for wakefulness, slow-wave sleep states 1 and 2, slow-wave sleep with pontogeniculooccipital waves, and REM sleep. Dependent variables quantified after each microinjection included the percentage of recording time spent in each state, the latency to onset of REM sleep, the number of episodes per hour for REM sleep, and the duration of each REM sleep episode. A total of 48 microinjections was made into 12 PPT sites in six cats. Microinjection of 0.3- and 1.0-μg doses of l-glutamate into the cholinergic cell compartment of the PPT increased the total amount of REM sleep in a dose-dependent manner. Both doses of l-glutamate increased REM sleep at the expense of slow-wave sleep but not wakefulness. Microinjection of 3.0 μg l-glutamate kept animals awake for 2–3 h by eliminating slow-wave and REM sleep. The results show that the microinjection of the excitatory amino acid l-glutamate into the PPT cholinergic cell compartments can increase wakefulness and/or REM sleep depending on the l-glutamate dosage. These findings unambiguously confirm the hypothesis that the excitation of the PPT cholinergic cells is causal to the generation of wakefulness and REM sleep. </jats:p

Abstract
This research aims to determine the relationship of the sociological aspects of the author with the inner structure of the poetry Watashi ga Ichiban Kirei Datta Toki by Ibaragi Noriko. This research uses descriptive analysis method, with the author\u27s sociology approach by Wellek and Warren (1994). This research was conducted by describing the object of research then analyzing the relationship of the sociological aspects of the author with the inner structure of the poetry. The result of this research is that there is a relationship between the sociological aspects of the author with the inner structure of poetry, namely on the aspect of the author\u27s social status with the theme and aspect of the author\u27s socio-cultural background with the mandate. From the results of this research, it can be seen that the poetry Watashi ga Ichiban Kirei Datta Toki was written by Ibaragi Noriko based on events that occurred in his life.

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
