    Science has influenced the modern day life and has never been more important to every aspect of social system than it is today. In today’s world more and more tough decisions have to depend on advances in modern science as all these advances are integral part of human existence. But on the other hand, it is becoming increasingly difficult for non-specialists to grasp those scientific advances which have been carried out at specialized centres. In modern specialist era even the best scientists are non-specialist outside their own area of inquiry. The political decision-making involves broad public participation through representations in every democratic system and therefore it is essential that the general public gain knowledge about the progress being made in science. Public should also know about the individuals, i.e., men and women, who are responsible and have contributed significantly to this progress

    Get PDF
    Let X be a completely regular Hausdorff space, E a Banach space, and Mtbv(X, M_{tbv}(X, E)E) the space of all E-valued tight measures of bounded variations. We prove some result about the weak compactness of some special subsets of Mtbv(X,E) M_{tbv}(X,E)

    Sugar has been an important commodity down through the ages. In the present day world, there is hardly any corner of the world where sugar is not consumed in one form or another

    Order convergence of vector measures on topological spaces

    summary:Let XX be a completely regular Hausdorff space, EE a boundedly complete vector lattice, Cb(X)C_{b}(X) the space of all, bounded, real-valued continuous functions on XX, F\mathcal{F} the algebra generated by the zero-sets of XX, and μCb(X)E\mu \: C_{b}(X) \rightarrow E a positive linear map. First we give a new proof that μ\mu extends to a unique, finitely additive measure μFE+ \mu \: \mathcal{F} \rightarrow E^{+} such that ν\nu is inner regular by zero-sets and outer regular by cozero sets. Then some order-convergence theorems about nets of E+E^{+}-valued finitely additive measures on F\mathcal{F} are proved, which extend some known results. Also, under certain conditions, the well-known Alexandrov’s theorem about the convergent sequences of σ\sigma -additive measures is extended to the case of order convergence

    Poverty Among Asian Americans: Theories and Approaches

    Get PDF
    Asian Americans are not immune to poverty and its consequences. This paper has reviewed several poverty-related concepts and theories and examined their relevance for understanding and dealing with poverty among Asian Americans. Social work interventions are proposed at both macro and micro levels together with the professional skills necessary for those interventions

    Oder-bounded sets in locally solid Riesz spaces

    Let E be Dedekind complete, Hausdorff, locally solid Riesz space and P an order bounded interval. We give a new proofs of Nakano’s theorem, that if E has Fatou property, P is complete, that the restrictions on P, of all topologies on E having Lebesgue property, are identical; we also give a measure-theoretic proof of the result that if (E,T) is a Dedekind complete, Hausdorff, locally convex-solid Riesz space with Lebesque property, then P is weakly compact and E is a regular Riesz subspace of E"

    Study and design of a business model for an internet company focused on very low earth orbit satellite constellation

    Get PDF
    This thesis is devoted to study and design a business model for an internet service provider company through a mega-constellation of satellites established on Very Low Earth Orbit (VLEO). The project starts by reviewing the state of the art of telecommunication industry, which includes a quick explanation about its history and evolution, followed by a short description about how does the satellite internet work and a brief analysis of the market situation. The main development of the thesis is the business design and the feasibility study; but before, it is performed a situation analysis through PESTEL and Porter forces study, which conclude in a SWOT matrix. After defining each block of the business model canvas, its conducted the feasibility study. Finally, the outcome presents interesting economic indicators, backed up with a sensitive stud

    Gauging students’ perception on biotechnology and cloning: Empirical evidences from India and Tanzania

    Get PDF
    For over the last two decades biotechnology and its techniques in various fields have attracted much media attention. All over the globe, syllabi have been directed to teach biotechnology and biotechnological techniques to undergraduate and post graduate students in almost all public funded and private universities. Biotechnology is beset with many ethical and social controversies. Earlier, there was much hue and cry at the introduction of ‘Genetically Modified foods’ and ‘Bt Cotton’ and even a muchhyped project like the ‘Human Genome Project’ did not achieve its pace because of ethical concerns.Social scientists started conducting opinion research on such ‘modern technologies’ before giving concrete shape to their adoption. In more recent years the issue of public perception, attitude and understanding towards science, in general, and towards specific technologies like genetic engineering, cloning, genetically modified foods, biotechnology and even nuclear technology, is increasing at a fast pace all over the world.One such study has been carried out registering the perceptions of undergraduate students who are studying biology subject in India and Tanzania, on biotechnology and cloning. The survey was conducted through a questionnaire (partially structured). This analysis revealed that students favoured production of genetically modified foods but they responded that ‘biotechnological experiments’ should be conducted on plants rather than animals. Furthermore, the students were strongly supportive of medical applications of biotechnology to avoid genetic diseases. Students from the two countries gave similar responses on some issues but differed on other issues. It is worth mentioning here that, though these perception survey studies are indicative yet these are quite important in framing policies related to the introduction of new technologies and framing strategies for communication/ popularisation of these issues among the general public

    25 Years of Public Understanding of Science in India: Analysis based on cultural distance

    Get PDF
    About 30 years ago the idea of cultural distance between peoples structure of thought and the science was proposed. Over the years it crystallised. This article presents major findings of the surveys thatwere conducted in India, spanned over twenty-five years. It is argued that cultural distance varies depending upon the nature of scientific information. Mapping cultural distances of specific scientificinformation for distinct target groups could help planners and communicators of science in devising effectual intervention strategies. Plans for dissemination of information that has low magnitude of cultural distance, need to be radically different in nature vis a vis approaches required for popularising scientific ideas that tend to cluster at the farthest end of the scale. In developing countries, the formal system of modern education operates as a strong determinant in shaping the cultural structure of thought prevalent among the citizens. It influences the worldview of even those who have never received any formal schooling and are categorised as ‘illiterate’

    Calculation of electro-optical parameters, a new approach. Part III. Applications to X<SUB>2</SUB>CZ molecules (X=H, F, Cl, Br and Z=O, S)

    Get PDF
    Calculations of electro-optical parameters by the modified first order approximation (MFOA) method have been extended to X2CZ (X=H, F, Cl, Br; Z=O, S) molecules with a view to investigate the transferability of these parameters. The diagonal and cross elements of the bond moment derivative matrix have been evaluated. Unique values of &#956;C-X are obtained for the A1 species. The bond moment derivatives are found to be transferable among A1 and B1 species. Transferability of the &#956;C-Z in B1 and B2 species is obtained for thiocarbonyl halides. Bond moment derivatives with respect to angle deformations are not found to be very significant whereas other cross elements of the bond moment derivative matrix are found to be of high magnitude
