An investigation of the barriers to e-business implementation in small and medium-sized enterprises
—E-business technologies, whereby business
transactions are conducted remotely using the Internet, present
unique opportunities and challenges for business. E-business
technologies are applicable to a wide range of organizations and
small and medium-sized enterprises (SMEs) are no exception. There
is an established body of literature about e-business, looking at
definitions, concepts, benefits and challenges. In general, however,
the research focus has been on larger organizations, not SMEs. In an
attempt to redress the balance of research, this paper looks at ebusiness
technologies specifically from a small business perspective.
It seeks to identify the possible barriers that SMEs might face when
considering adoption of the e-business concept and practice as part of
their business process change initiatives and implementation. To
facilitate analysis of these barriers a conceptual framework has been
developed which outlines the key conceptual and practical challenges
of e-business implementation in SMEs. This is developed following a
literature survey comprised of three categories: characteristics of
SMEs, issues of IS/IT use in SMEs and general e-business adoption
and implementation issues. The framework is then empirically
assessed against 7 SMEs who have yet to implement e-business or
whose e-business efforts have been unsatisfactory. Conclusions from
the case studies can be used to verify the framework, and set
parameters for further larger scale empirical investigation

Traditional practices of utilization and conservation of non-wood forest products by Adi tribes of Arunachal Pradesh
The survey was carried out during 2009-11 to collect the information of Non-Wood Forest Products (NWFPs) utilized by the Adi tribes of East Siang District of Arunachal Pradesh. It was observeds that Adi tribes used to collect different NWFPs such as wild fruits (Artocarpus heterophyllum Lam., Castanopsis indica (Roxb. ex Lindl.) A. DC., Canarium strictum Roxb. etc.), vegetables (Bauhinia variegata L., Clerodendrum colebrookianum Walp., Diplazium esculentum (Retz.) Sw., Moringa oleifera Lam. etc.), spices (Cinnamomum tamala Nees & Eber.,Cinnamomum zeylanicum Blume. and Piper longum L.), fibres (Calamus flagellum Griff. ex Mart., Dendrocalamus hemiltonii Nees et Arn. ex Munro, Pandanus nepaulensis H. St. John and Sterculia villosa Roxb.), floss (Bombax ceiba L.,), broom grass (Thysanolaena maxima (Roxb.) Ktze.), thatching material (Livistona jenkinsiana Griff.), various bamboo and cane species, and other miscellaneous products from the forests and community lands. NWFPs played a significant role in supporting the livelihood of Adi tribes as it has been observed that 32.50 %, 56.67 % and 10.83 % people were earning < Rs. 3000, Rs. 3000 - 6000 and > Rs. 6000, respectively from the sale of different NWFPs. Majority of respondents (80.83 %) were having the opinion that the availability of different NWFPs has declined considerably and maximum (85 %) respondents advocated that the availability of these products would further decrease in future also. Further, Adi tribal community is playing an important role in conservation of different NWFPs yielding species by domesticating them in their home gardens
A semi-analytical approach to perturbations in mutated hilltop inflation
We study cosmological perturbations and observational aspects for mutated
hilltop model of inflation. Employing mostly analytical treatment, we evaluate
observable parameters during inflation as well as post-inflationary
perturbations. This further leads to exploring observational aspects related to
Cosmic Microwave Background (CMB) radiation. This semi-analytical treatment
reduces complications related to numerical computation to some extent for
studying the different phenomena related to CMB angular power spectrum for
mutated hilltop inflation.Comment: 7 pages, 2 figures. Improved version to appear in IJMP

The Berry phase in inflationary cosmology
We derive an analogue of the Berry phase associated with inflationary
cosmological perturbations of quantum mechanical origin by obtaining the
corresponding wavefunction. We have further shown that cosmological Berry phase
can be completely envisioned through the observable parameters, viz. spectral
indices. Finally, physical significance of this phase is discussed from the
point of view of theoretical and observational aspects with some possible
consequences of this quantity in inflationary cosmology.Comment: 9 pages, Modified version to appear in Classical and Quantum Gravity.

Mutated Hilltop Inflation : A Natural Choice for Early Universe
We propose a model of inflation with a suitable potential for a single scalar
field which falls in the wide class of hilltop inflation. We derive the
analytical expressions for most of the physical quantities related to inflation
and show that all of them represent the true behavior as required from a model
of inflation. We further subject the results to observational verification by
formulating the theory of perturbations based on our model followed by an
estimation for the values of those observable parameters. Our model is found to
be in excellent agreement with observational data. Thus, the features related
to the model leads us to infer that this type of hilltop inflation may be a
natural choice for explaining the early universe.Comment: 22 pages, 7 figures, 2 tables. Matches published version in JCA
