Sustainable Tourism and Management for Coral Reefs: Preserving Diversity and Plurality in a Time of Climate Change  [PDF]
M. James C. Crabbe
Journal of Service Science and Management (JSSM) , 2010, DOI: 10.4236/jssm.2010.32031
Abstract: Coral reefs throughout the world are under severe challenges from a variety of anthropogenic and environmental factors. In a period of climate change, where mobility and tourism are under threat, it is useful to demonstrate the value of eco- and research-tourism to individuals and to cultures, and how diversity and pluralism in sustainable environments may be preserved. Here we identify the ways in which organisations use research tourism to benefit ecosystem diversity and conservation, show how an Earthwatch project has produced scientific information on the fringing reefs of North Jamaica, and how a capacity-building programme in Belize developed specific action plans for ecotourism. We discuss how implementation of those plans can help research tourism and preserve ecosystem diversity in times of climate change.
Production of Phosphate-Rich Biofertiliser Using Vermicompost and Anaerobic Digestor Sludge—A Case Study  [PDF]
C. M. Narayanan
Advances in Chemical Engineering and Science (ACES) , 2012, DOI: 10.4236/aces.2012.22022
Abstract: This paper presents the technology and cost effectiveness of production of phosphate rich biofertiliser (called PROM) by bioconversion of phosphate rock ore into soluble phosphates (that are directly assimilable by plants) in presence of an organic manure such as Vermicompost or anaerobic digestor sludge (discharged from biogas manufacturing units) and using a microbial culture of Bacillus megatherium var phosphaticum. PROM has been found to be an excellent, less expensive, substitute to synthetic phosphatic fertilisers such as SSP, MAP and DAP. This is based on real—life field trials. It is also possible to integrate the production of PROM, with biogas generation and the layout of such a more profitable, integrated scheme is also presented in this paper.
Identifying the Intellectual Virtues in a Demon World  [PDF]
M. C. Young
Open Journal of Philosophy (OJPP) , 2012, DOI: 10.4236/ojpp.2012.24036
Abstract: Within contemporary epistemology, notions of intellectual virtue have come to fulfill a prominent role in attempts to provide an account of knowledge. Notions of such virtue can vary, and one particular aspect of this variance concerns how to construe the relationship between the intellectual virtues and particular epistemic ends. The goal of this article is to defend an instrumental connection between the intellectual virtues and the epistemic end of true belief. One type of skeptical argument that attempts to sever this connection, a Cartesian Demon argument, is considered. This Cartesian Demon argument will be summarized, as well as three responses to it. The claim that truth-conduciveness is a tenable criterion for identifying the intellectual virtues is then defended. It is acknowledged that the possibility of a Cartesian Demon does initiate scepticism, but that this scepticism is directed toward identifying specific intellectual virtues and not toward the instrumental connection between intellectual virtue and true belief.
Growth, Structural, Spectral and Optical Studies on Pure and L-Alanine Mixed Bisthiourea Cadmium Bromide (LABTCB) Crystals  [PDF]
M. Senthilkumar, C. Ramachandraraja
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.116046
Abstract: Pure bisthiourea cadmium bromide (BTCB) and 1 mole % L-alanine mixed bisthiourea cadmium bromide (LABTCB) single crystals have been grown by slow evaporation method. The grown crystals have been characterized by single crystal XRD analysis, powder XRD analysis, FTIR analysis, UV-Vis-NIR analysis and SHG studies. XRD analysis confirms the crystalline nature of the materials. The addition of L-alanine changes the crystal structure from orthorhombic to tetragonal. The presence of various functional groups present in the pure BTCB and LABTCB crystals have been confirmed by FTIR analysis. The UV-Vis-NIR spectrum shows the transmission characteristics of the crystals. The SHG study depicts the nonlinear optical efficiency of the crystals.
Comparison of Two Reef Sites on the North Coast of Jamaica over a 15-Year Period  [PDF]
M. James C. Crabbe
American Journal of Climate Change (AJCC) , 2016, DOI: 10.4236/ajcc.2016.51002
Abstract: This paper compares two reef sites near Discovery Bay, Jamaica, Dairy Bull and Dancing Lady, from 2000 to 2015. At Dairy Bull reef, with low macroalgal cover (8% in 2002 falling to 1% in 2015) and significant number of Diadema antillarum urchins (c. 5 m-2), live coral cover increased from 13% ± 5% in 2006 after the bleaching event in 2005, to 31% ± 7% in 2008, while live Acropora cervicornis increased from 2% ± 2% in 2006 to 28% ± 5% in 2015. Coral cover levels were at least maintained until 2015, owing mostly to a slight increase in A. cervicornis. Dancing Lady reef however was dominated by macroalgae throughout this period (cover of c. 76% ± 7%), with no D. antillarum and showed little decrease in the already low (6% ± 1%) coral cover in 2005. Growth rates for Siderastrea siderea were similar for both sites (7 mm·yr-1), while growth rates of A. cervicornis and A. palmata were 120.0 ± 30 mm·yr-1 and 71.0 ± 29 mm·yr-1 respectively at Dairy Bull in 2015. At Dancing Lady reef, A. cervicornis colonies which were present from 2003 to 2005 had disappeared in 2006, possibly as a result of the mass bleaching event. It appears that A. cervicornis was the most impacted species during the 2005 bleaching event, but was also the species that recovered fastest after its decline at Dairy Bull.
Do Macroeconomic Indicators Stimulate FDI Inflows in India?  [PDF]
M. C. Minimol
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.77144
Abstract: The current study mainly attempts to find out whether macroeconomic indicators actually stimulate the inflow of FDI into India. The study also attempted to check whether there is any long run or short run relationship between the macroeconomic indicators and FDI inflows into the country using regression analysis, Cointegration test, Granger causality and Vector error correction model. The results show that the explanatory variables captured in the model well explained the variations in FDI Inflows. However, not all the explanatory variables considered in the model are statistically significant in explaining the behavior of FDI. Unrestricted Cointegration Trace statistic and Max-Eigen statistics supports the existence of cointegrating relationship among the variables. The study also shows that SENSEX and NIFTY do granger cause FDI in the long run while, FDI does not granger cause neither of the two. S Vector Error Correction Model supports the absence of short-run relationship among the macroeconomic indicators and FDI inflows in India.
Relationship between Spot and Future Prices of Crude Oil: A Cointegration Analysis  [PDF]
M. C. Minimol
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.83023
Abstract: The study was intended to reveal the relationship among the spot and future price of crude oil, which in turn will help in determining the prices of crude oil. While structuring a portfolio, high correlation among assets alone cannot be taken as a satisfactory measure for long run diversification paybacks. There is a crucial need to enhance the traditional risk-return modeling methodologies by giving due consideration to common long term trends among the asset prices. Considering this pressing need, the present paper attempts to explore the long run and short run relationship between spot and future prices of crude oil using time series data. To estimate the long and short run dynamics of crude oil prices, the present study applies the Johansen cointegration, and vector error correction modelling to time series analysis.
A Canonical Correlation Analysis of Sectoral Composition of GDP and Development in Asia  [PDF]
C. M. Jayadevan
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.92024
Abstract: This paper identifies the factors that influence percentage contribution of sectors to gross domestic product (GDP) for a group of 32 Asian countries for two cross-section points 1994-96 and 2014-16. Development theories hypothesize that the percentage share of sectors to GDP undergoes transformation with the level of economic development of the country and the degree of competitiveness of its agricultural sector. This paper employed the use of a canonical correlation analysis for 32 Asian countries. This analysis shows that the structural changes in sectoral GDP composition in the selected Asian countries were significantly determined by the factors like employee productivity, employment growth in services sector, rising life expectancy, growth of value added in manufacturing and gross capital formation.

C. M. Sunil, B. C. Shankaralingappa
Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.51006

A field experiment was conducted during Kharif, 2011-2012 and 2012-2013 at GKVK, Bengaluru, Karnataka to study the effect of integrated package of agrotechniques on growth and yield of aerobic rice. The predominant weed flora observed in the experimental field were, Eleusine indica, Digitaria marginata L., Dactyloctenium aegyptium L., Alternanthera sessilis, Mollugo distica L., Celosia argentia and Borreria hispida. Treatments receiving integrated weed management practices recorded significantly lower weed population and weed dry weight as compared to pre-emergence application of pyrazosulfuron ethyl alone. Application of RDF + FYM + Biofertilizers + FeSO4 +IWM practices (T8) recorded significantly higher growth, yield parameters and yield as compared to RDF + FYM + IWM practices and was being on par with RDF + FYM + Biofertilizers + IWM practices (T5).

The Effect of Laminate Angles in Composite Substrates on the Performance of Rectangular Microstrip Antenna  [PDF]
C. C. Hung, S. M. Yang
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2016, DOI: 10.4236/jemaa.2016.812024
Abstract: The performance of a microstrip antenna has been known sensitive to substrate’s dielectric properties, which is dependent on the angle of laminate layers inside a composite laminated substrate. Modal analysis in spectral domain is applied to investigate the resonant frequency and radiation pattern of rectangular microstrip antenna on composite substrates. It is shown that the substrate’s dielectric properties are dependent upon the laminate angles, i.e., upon the orientation of the antenna relative to the substrate’s fiber direction. For the same operating frequency, the antenna size on composite substrates is larger than that on isotropic substrates, and the far field pattern is also more directional.
