Developing Policy Inputs for Efficient Trade and Sustainable Development Using Data Analysis
Trade forms a vital part of the world economy. The analysis of data on trade and related parameters plays a pivotal role in developing policy inputs for efficient trade and sustainable development. It is evident that the success of any type of analysis depends on the availability of the suitable type of data. In general, time series, cross sectional and pooled data are the three types of data available for trade analysis. Time series data are characterized by observations collected at regular intervals over a period of time while cross-sectional data are data on one or more variables collected at the same point of time. The pooled data is a combination of time series and cross-sectional data. For example, panel data, which is a special type of pooled data is used to study the relationship between trade flows and trade barriers over time. In recent years, the quantitative and qualitative analysis of trade and the effects of policies have grown sharply. This was due to the advances in the theoretical and analytical techniques as well as increased computational and data processing power of computers

Sampling methodology employed by CMFRI for monitoring the fishery and estimation of marine fish landings in India
Fisheries sector plays a key role in Indian economy. The sector supports livelihood, nutritional
security, and subsistence to large number of people as well as foreign exchange earnings.
IndiaтАЩs coast line stretches about 8129 km. There are 1355 landing centres scattered along
the coastline of the main land as per the records from National Marine Fisheries Data Centre
at Central Marine Fisheries Research Institute (CMFRI). Marine fish landings take place
almost all along the coast line throughout the day and sometimes during night. Under
these circumstances, collection of statistics by complete enumeration would involve a very
large number of enumerators and a huge amount of money apart from the time involved
in collection of data. Therefore, a possible solution for quantifying marine fish landings is
adoption of a suitable sampling technique. As, monitoring and assessment of the exploited
marine fishery resources of India is one of the important mandates of the CMFRI, institute
made attempts to evolve the scientific methods for collection of data on catch and effort,
since its inception in 1947. Pilot surveys were conducted along the coastline of India and
different sampling designs were tested
Monitoring and Quantifying Marine Fish Landings in India: Survey Design, Sampling and Estimation followed by CMFRI
In the existing sampling methodology, the interest is to
estimate gear-wise, species-wise landings for the state in a
month, fishing effort according to different types of fishing
boats and also in terms of man hours. The analysis is carried
out at CMFRI headquarters. Before the data is processed for
analysis it will be ensured that the data collection is made
as per the approved schedule, by checking the appropriate
proforma. The responsibilities and functions of staff at the
headquarters are data coding, estimation and database
management. The data analysis is computerised and
estimates are made using the software developed by the
Fishery Resources Assessment Division of the Institute. The
processed data are again counter- checked for errors. When
discrepancies are detected, the estimation procedure is
scrutinised in detail
Introduction to Computers
Our lifestyles have undergone a sea change with the advancement in technology
especially in the field of computers. Computers are an integral part of our lifestyles
today and are found at offices, banks, homes, schools, colleges, hotels, shops etc. This
advance in technology has made our lives easy and comfortable. For instance, we can
execute a number of activities using computer based systems- we can write a draft on
word processor and email it, make calculations using an electronic spread sheet and
incorporate graphics, create a
database of friends with their phone
numbers, addresses and e-mail ids
etc. This chapter gives overview of
components of computer, different
types of input and output devices,
different types of memory,
classification of computer, various
computer generations, different types
of computer languages and various
applications in todayтАЩs arena
Study on evaluation of CMFRI sampling design for estimation of marine fisheries resources in Kerala
Fishing has been a traditional occupation of a section of people all
over the world from time immemorial. In India, the fisheries sector
contributes significantly towards strengthening nutritional security, income,
employment, foreign exchange earnings and livelihood opportunities. These
facts established the fisheries sector as an important enterprise of Indian
economy. During the last six decades, Indian fisheries had made
tremendous progress, with the annual fish production increasing from 0.75
million tonnes in 1950 to 6.4 million tonnes in 2006, indicating over
eight fold increase during the period. As per the latest available data, marine
fishery sector earns a foreign exchange of Rs. 8000 crores annually through
seafood export

Internet and E-Mail
Internet is a worldwide system of interconnected
computer networks. It connects several millions
of computers all over the world. There is no
central computer. All computers are placed at
different places and are connected to each other
by phone lines, cables or wireless connections.
Any two computers connected to the internet can
exchange information. The internet is therefore a
very fast and efficient way of sending information.
According to recent statistics, there is an
estimated 3,179,035,200 internet users worldwide. The number of Internet users
represents nearly 40 per cent of the world's population. The largest number of
Internet users is in China, followed by the United States and India.
This chapter is organized as follows. It gives an introduction to internet and its
applications in day to day life followed by basic requirements for connecting to
internet. Subsequently a brief on World Wide Web, Web browsers, search engines,
online safety measures are given. Lastly, a step by step procedure for creating e-mail
ID is given in the chapter
