Economic growth and inter-sectoral linkages in India
The process of economic development in an economy results in distinct structural changes. As a country progresses and the gross domestic product (GDP) basket enlarges, a shift in economic activity occurs away from agriculture towards services and manufacturing sectors, owing to higher elasticity of the latter two sectors than that of former sector. The process in turn leads to structural shifts, and consequent diminishing significance of primary activities and growing dominance of secondary and tertiary activities. This process brings with it significant changes in the production process, consumption pattern and various other social indicators. An in-depth understanding of inter-sectoral dynamics becomes all the more important for policy makers so that effective monetary, credit and fiscal policies could be designed in order to be able to achieve the broader objective of inclusive development. In this backdrop, the present paper endeavors to study linkages between agriculture and other Sectors in the Indian economy both through input-output (I-O) approach

Effect of dietary administration of the phytochemical “genistein” (3,5,7,3,4 pentahydroxyflavone) on masculine tilapia, oreochromis niloticus
In Tilapia aquaculture, it is more desirable to culture all male (monosex) population because they grow bigger and faster. The synthetic steroid hormones such as 17-?-methyl testosterone are commonly used to reverse sex in tilapia. Due to its latent health and environmental hazards, attention is presently being focused on the use of alternatives, such as plant extracts called phytochemicals. This study investigated the phytochemical “genistein” as a possible enzymatic aromatase inhibitor that could modulate the sex differential response in the gonad of sexually undifferentiated tilapia. Experimental diet supplemented with genistein (500mg/kg) along with a control diet were evaluated in the feeding of three days old tilapia fry (6mg-8mg) for eight weeks. Result shows that the presence of dietary genistein did not have any significance positive effect on the weight gain, SGR (%) and survival (%), although higher number of males were produced in the genistein fed fish but the phenotypic sex ratio was not significantly different (p>0.05) from the control.

The general aim of this study is to investigate the effect of exchange rate on financial performance of small and middle-sized companies in Mogadishu.Specifically, this study investigated the effects of Balance of payments, the effect of foreign direct investment, the degree of Inflation and the effect of Taxation. The related theories of exchange rate are Purchasing power Theory, Interest Rate Theory and Product Cycle Theory. This study was conducted through a descriptive study. In addition the study employed a survey research design in data collection. The sampling procedure of this study used non-probability sampling procedure particularly purposive sampling or judgmental sampling, this research employed quantitative data collection method whereby data was gathered by the use of closed ended questionnaires which are self-administered. The data collected was analyzed using the software called Statistical Package for the Social Sciences (SPSS) version 22 and results shown in terms of frequency distribution and percentages, the target population of the study is 160 employees of some merchandising companies in Mogadishu. A sample of 48 respondents was selected using Mugenda and Mugenda?s formula. The study used primary data. Data collection methods used included use of questionnaires. The selection sample technique was purposive or judgmental approach. A regression model was applied to determine the relationship between Balance of payments, foreign direct investment, inflation and Taxation as the independent variables and financial performance for small and medium sized enterprises as the dependent variable. The key findings of this study were: Most of the respondents agreed that International trade has a direct effect on the financial performance of the company. Most of the respondents also agreed to the fact that Company owners think they can create high profit for the company if they gain investment income. Company managers are always responsible when companies fail to implement financial transactions. The researchers recommended that: Somali merchants should try to increase domestic productions so as to add value to their money. The researcher?s second recommendation is that Somali government should control all import-export activities and try to increase exportations rather than importation Also top management of small and medium sized enterprises should motivate their employees to increase the performance.

English language teaching in a globalized and digital age: implications for teacher preparation and professional development in Nigeria
The spread of English as an international language and the emergence of the Internet as a fast communication channel are dual issues that define ELT in a globalized and digital age. Since its conception, the Internet has revolutionized the ways of human communication as well as English language learning in a global context. But the implications of this powerful force are yet to be fully recognized and realized in education and teacher education in Nigeria. Teachers of English language as well as learners of the language today need a new set of critical and interpretive skills. This paper attempts to discuss the impact of the Internet on English language learning as well as the need for new frameworks for teaching English language in a digital age in Nigeria.

Estimation of some metal and quality profile of Cocoa beans in Ghana
Toxic heavy metal monitoring in the environment and food is a key requirement for protection against the hazards of metal toxicity. The concentrations of heavy metals (Mercury, Copper and Cadmium) and other elements (Vanadium, Magnesium, Manganese, Calcium and Chloride) in cocoa beans from 73 district representing six of the seven cocoa regions for the 2011/2012 light crop year were analyzed using Neutron Activation procedures to look at the distribution of metals, especially heavy metals in the beans meant for export. Certain basic quality parameters such as pH, moisture and percentage fat content were also measured. Analysis of cocoa beans yielded the following results; Calcium (Ca; 2155 -5863, average 3443.20 mg kg?¹) showed the highest concentration, followed by Magnesium (Mg; 2147 to 4601 mg kg?¹, average 3227.02 mg kg?¹) and Aluminium (Al; 32.86 -147.40, average 54.32 mg kg?¹). Manganese (Mn) was also found to range between 19.66 -50.01; average 35.40 mg kg?¹. Vanadium and chloride were on the average 0.20 and 82.37 mg kg?¹ respectively. Amongst the heavy metals analysed, Cadmium (Cd) was in the range of <0.01 and 48.30 µg kg?¹, well below the proposed MRL of 0.6 mg Kg?¹ whereas mercury was below 0.01µg kg?¹, the detection limit of the NAA method used. Copper (Cu) was in the range of 10.04–26.76 mg kg?¹ in the beans analysed. Fat content of the beans were higher than 52.63% with a pH range of 4.52-5.58, typical of Ghana’s cocoa. The results showed that heavy metal concentrations in the beans are generally low with accompanying high quality indicators. Although levels of these heavy metals are very low, a potential danger may emerge in the future depending on the management of soil pollution since soil-to-plant transfer of heavy metals is a major pathway to product pollution.

Evaluation of Potentials of Two Uncultivated Plants Parts (Artocarpus heterophyllus and Parkia biglobosa)
The major component of wastes from uncultivated plants that constitutes environmental problems is seed. Artocarpus heterophyllus seed and Parkia biglobosa seed pulp were investigated for proximate composition, chemical and antibacterial properties of their oils with a view to exploiting their nutritional and industrial potentials. The crude protein, crude fibre and crude fat content were 14.02, 5.25; 1.23, 12.00; 26.5, 18.00 g/100g respectively. The high iodine value of the fixed oils; 1788, 1425 g iodine kg-1 oil respectively compared favourably with edible oils, while the high saponification values of 296.14 and 193.12 g KOH kg-1 suggested they are good feedstock for the soap industry. The seed and seed pulp essential oils could also find application as antibacterial agent to extend the shelf life of easily perishable food products.

Evaluation of the chemical composition and antimicrobial activities of three Nigerian medicinal plants
Nigeran medicinal plants (Acanthospermum hispidum DC, Emilia coccinea (Sims) G. Don and Euphobia heterophylla) were analysed for their chemical composition. Phytochemical screening indicates the presence of saponins (0.22 to 0.37 mg/100g), flavonoids (0.96 to 1.87 mg/100g), alkaloids (1.52 to 1.71 mg/100g), phenols (1.07 to 1.55 mg/100g) and tannins (0.06 to 0.37 mg/100g). The medicinal plants contained ascorbic acid (24.35 to 31.79 mg/100g), riboflavin (0.04 to 0.31 mg/100g), thiamin (0.20 to 0.22 mg/100g) and niacin (0.08 to 0.10 mg/100g). These herbs are good sources of minerals such as Ca, P, K, Mg, Na, Fe and Zn. The plants gave appreciable antimicrobial activities in vitro against both gram-negative and gram-positive microorganisms with the zone of inhibition values ranging between (16.00mm – 32.00mm) and (11.00mm – 22.00mm) respectively. The importance of these chemical constituents is discussed with respect to the role of these herbs in ethnomedicine in Nigeria.
