Social Network Analysis

Billions of people create trillions of connections through social media each day, but few of us consider how each click and key press builds relationships that, in aggregate, form a vast social network. Passionate users of social media tools such as email, blogs, microblogs, and wikis eagerly send personal or public messages, post strongly felt opinions, or contribute to community knowledge to develop partnerships, promote cultural heritage, and advance development. Devoted social networkers create and share digital media and rate or recommend resources to pool their experiences, provide help for neighbors and colleagues, and express their creativity. The results are vast, complex networks of connections that link people to other people, documents, locations, concepts, and other objects. New tools are now available to collect, analyze, visualize, and generate insights from the collections of connections formed from billions of messages, links, posts, edits, uploaded photos and videos, reviews, and recommendations. As Continue reading

Investments in Mutual Funds – Maximize Returns with Mutual Funds

Mutual fund companies [also known as Asset Management Companies (AMCs) collect funds from public (mainly from small investors) and invest such funds in market and distribute returns/surpluses in the form of dividends. Surpluses can also be reflected in higher Net Asset Value (NAV) of the scheme. In simple words, a mutual fund company collects savings of small investors (pool their money); the fund managers of the concern invest such pool of funds to market (securities); when returns are generated from such investment, passed back to the investors. This is how a mutual fund works. First an offer document (containing details of the scheme, its investment horizon and class(es) of securities it intends to invest etc.) is issued to the public. Then the collected money is pooled together to constitute a fund. This fund is managed by fund managers of AMC who take major investment decisions. A trust takes care that Continue reading

Case Study: Southwest Airlines Competitive Advantages

For most of the last fifteen years, the U.S. airline industry has been one of the least attractive to be in. Following the 1978 deregulation of the industry, twenty-nine new airlines entered the industry between 1978 and 1993- This rapid increase in air ­line carrying capacity led to a situation of overcapacity. As more and more airlines chased passengers, fares were driven down to levels barely sufficient to maintain the prof ­itability of U.S. airlines. Indeed, twice since 1978 the indus ­try has been engulfed in an intense price war–first in the1981-1983 period and then again in the 1990-1993 period. So intense did the com ­petition become during these two periods that in 1982 the whole industry lost $700 million, while in the 1990-1992 period the industry lost a staggering $7.1 billion, more than had been made during the previous fifty-year history of the industry. Despite the obviously hostile nature Continue reading

Scope of Grid Computing

EXPLOITING UNDERUTILIZED RESOURCES The easiest use of grid computing is to run an existing application on a different machine. The machine on which the application is normally run might be unusually busy due to an unusual peak in activity. The job in question could be run on an idle machine elsewhere on the grid. There are at least two prerequisites for this scenario. First, the application must be executable remotely and without undue overhead. Second, the remote machine must meet any special hardware, software, or resource requirements imposed by the application. In most organizations, there are large amounts of underutilized computing resources. Most desktop machines are busy less than 5 percent of the time. In some organizations, even the server machines can often be relatively idle. Grid computing provides a framework for exploiting these underutilized resources and thus has the possibility of substantially increasing the efficiency of resource usage. Another Continue reading

The Effect of Organizational Structure on Innovation

Organizational structure is the skeleton system based on which an organization functions.  Organizational structure deals with the framework which defines the relation between people and positions in the organization. Organization structure is defined as the formal system of task and reporting relationships that controls, coordinates and motivates employees so that they cooperate and work together to achieve an organization’s goals. Several tasks are to be implemented in an organization, for these organizational tasks to be successful, they should be coordinated. Organizational structure supports division of work, categorizing the tasks and supervision in an organization. An effective organizational structure aids the efficient running of an organization. The factors that govern the formulation of an organizational structure are benefits of channelizing the tasks, hurdles due to communication and obstacles due to formatting the authority levels. Organizational structure helps the managers in a firm to describe, distribute and get job done. Organizational structure Continue reading

Factors Affecting / Limiting Consumption

As the demand for a good depends upon its price, similarly consumption of a community depends upon the level of income. In other words, consumption is a function of income. The consumption function relates the amount of consumption to the level of income. When the income of a community rises, consumption also rises. How much consumption rises in response to a given increase in income depends upon the propensity to consume or consumption function. It should be borne in mind that the consumption function or the propensity to consume is the whole schedule which describes the amounts of consumption at various levels of income. Consumption is the sole end and purpose of all production. What restricts consumption? The factors which limit consumption are: The product and its limitations: This is a part of market research which is of great importance to product development and design.   Solution may be obtained Continue reading
