Radio as medium of mass communication

Radio is widely used mass communication medium and has a great potentiality in dissemination of information as radio signals cover almost entire world. More than 177 radio stations are there across the country. Almost 97 percent of the population is reached by the radio. Radio being a convenient form of entertainment caters to a large audience. With the invention of transistors this medium has reached the common man in urban and rural areas of India but the utilization of radio is more among rural elites.It has advantages over the other mass media like television and newspapers in terms of being handy, portable, easily accessible and cheap. Radio is the most portable of the broadcast media, being easily accessible at home, at office, in car, on the street or beach, virtually anywhere and everywhere at any time. Radio is effective medium not only in informing the people but also in creating awareness regarding many social issues and need for social reformation, developing interest and initiating action.For example, in creating awareness regarding new policies, news about evelopmental projects and programs, new ideas etc. It will help in creating a positive climate for growth and development. It widens the horizons of the people and enlightens them, and gradually changing their outlook towards life. Research about this has shown that radio is an effective medium for education when it is followed up with group discussion and question- answer session. In India, radio with its penetration to the rural areas is becoming a powerful medium for advertisers.It gains 3 percent of the national advertising budget. Radio is still the heapest alternative to television, but it is no longer the poor medium in advertising terms. Because radio listening are so widespread, it is prospered as an advertising medium for reaching local audiences. Moreover, the radio serves small and highly targeted audiences, which makes radio an excellent advertising medium for many kinds of speciali zed products and services. As far as commercials are concerned, no one will able to tune out commercials easily as is possible with remote control devices and VCRs.It is said that radio's ability to ttract local advertisers hurts mainly newspapers, as television is less attractive to the small and local advertiser. As tar as audience is concerned radio does not hamper persons mobility. Radio as a vehicle of information for masses it is still the fastest medium of communication. For instance, it would take less time for a news reporter for radio to arrive on the spot with a microphone and recorder than the same for TV along with a shooting team and equipment.Another important feature of radio as mass medium is that it caters to a large rural opulation which has no access to TV and where there is no power supply. In such places, AIR-AII India Radio's programmes continue to be the only source of information and entertainment. AIR broadcasts programmes in 24 languages and 140 dialects. â€Å"Radio should be treated as a kin to newspapers in view of the fact that it is local, inexpensive, linked to communities, has limited band width and operates through simple technology'. The economics of radio does allow tailoring programme content to the needs of small audiences.Thus it is economically viable to recast a programme for broadcast to audiences in different sub regional, cultural and linguistic language. This enhances the value of radio as a medium in networking developmental programmes. It offers many possibilities in networking, from local or regional co- ordinated broadcasts and interactive exchange of queries and data. It will serve as a standalone medium of information dissemination or a support medium for curricular learning, Jointly with print material or with fieldwork.

Development of syllabuses in schools Essay

How did the changing role of women and our view of children affect the development of syllabuses in schools? As history progressed peoples attitude towards women and children changed for the better. As a result of the two world wars, women and children were able to prove their importance, enabling them to increase their value within the community. As these changes in our perception of women and children occurred, syllabuses in schools were altered. The 1902 model course was developed, as people believed that it was up to children to do physical training at school to prepare them for war. Although it was grown men that had previously been defeated in the Boer war, the loss was blamed on the lack of physical training provided in schools. This is an example of children being considered important for the future of Britain. The model course, however, soon came under attack as it had children doing exercises designed for adults. As a result of this a new syllabus was introduced in 1904 and was more child-friendly. The 1909 syllabus was developed as more concern was being taken over the welfare of children of working-class families and this syllabus ensured a slightly more therapeutic angle. Organised games were introduced in this syllabus; this shows the first tentative move away from military-style Physical Training teaching. The years 1914-1918 saw the tragedy of the First World War. A generation of young men was almost totally wiped out. Consequently this had an effect on the education system, as it was recognised that a more child centred approach was needed. The First World War also improved the social status of women. This was because they had worked in munitions factories and on the land whilst the men were busy fighting. Women proved that they could cope with demanding physical work and this afforded them more equality. Despite this development in the way in which they were viewed, women generally continued to have only limited access to sport. In 1919, after the war a new syllabus was introduced. This syllabus was more child orientated than the previous ones It allowed more freedom and individual interpretation. For the older pupils therapeutic exercises were still the main emphasis. The 1933 syllabus is perhaps one of the most significant syllabuses developed as a result of the way in which children were viewed. It was developed after the economic depression, which started in the late 1920s. During this time there were very poor living conditions for the less well off as they suffered even more than they had done previously. In this syllabus we see a move from a teacher-centred approach to one where more choice is available and decisions can be made by pupils. This is signif8icant as it shows that adults were beginning to view children as being independent and therefore able to make there own decisions. Everyone was touched by the Second World War. Due to the development of aircraft bombers and long-range missiles, the lives of everyone in Britain, including children were affected. People now looked to their children for hope and we now see a further step towards child-centred learning. The training that had been used to create ‘thinking’ soldiers during the war was now adapted to suit schools. Assault course type equipment was put up in schools. Pupils were required to use their initiative and take responsibility for each other.

Analysis of gene research papers

Analysis of gene research papers Source: Ledford, H. (2017, March 07). CRISPR: gene editing is just the beginning. Retrieved July 05, 2017, from http://www.nature.com/news/crispr-gene-editing-is-just-the-beginning-1.19510 CRISPR has signaled a new age for molecular biologists, and non-profits like Addgene are on top of it all. Addgene has become the place where scientists deposit their tools while also turning to them in search of molecular tools. CRISPR now resembles something novel for researchers all around the world: Specificity – the ability to do exactly what they want and just what they want. The CRISPR tool can be used in many ways to suit the needs of the researcher. A common technique being used it to observe the effect of a change in the genetic code (particular genes) on the cell. This allows for a deeper understanding of metabolic pathways and effects of proteins and genes. The CRISPR associated protein 9 (CRISPR Cas9) is the enzyme which is in widespread use in laboratories. Researchers from Stanford University modified the Cas9 to just inhibit the gene, and not cutting the gene (as it would normally). The brilliancy of CRISPR is the fact that it itself has been modified and we can attach molecules that affect the epigenetics of the cell, that can be induced by specific stimuli and we can attach molecules that can even stimulate the expression of a particular gene. The ability of this tool to modify the epigenome with high specificity has massive implications as the epigenome has been linked to issues like cancer and neurological disorders. Lastly, CRISPR has had a major positive impact on the economical side of research by reducing both the time taken and cost of experiments considerably. For instance, CRISPR has enabled researchers to do what previously took a year in just a month! Article 2: Source: Larson, C. Schaffer A. (2016, October 04). New Tools for Editing the Genome Could Radically Change the Study of Human Diseases. Retrieved July 05, 2017, from https://www.technologyreview.com/s/526511/genome-editing/ Genetic editing using the CRISPR-Cas method is revolutionizing the world and has transformed the scenario of many labs throughout the world. It now provides a cheap and highly precise method of gene editing. CRISPR is a tool born from the collaboration between scientists from varied backgrounds pursuing a common goal. Recent research in China has proven the possibility of genetically edited macaques and this is a stepping stone towards â€Å"designer babies†. The introduction of ethical dilemmas due to the advent of this technology is an inevitable repercussion of any powerful tool. However, the success of the aforementioned experiment seeks to showcase the importance of primate models in research. Primate models have also been useful in understanding genetic diseases and mutations and CRISPR now allows researchers to identify these mutations and find gene therapies to it.

High-throughput siRNA screening as a method of perturbation of biological systems and identification of targeted pathways coupled with compound screening. Retrieved July 05, 2017, from https://www.ncbi.nlm.nih.gov/pubmed/19597791 There are two ways to screen cells containing the CRISPR Cas9 nucleases that knockout specific genes: pooled format and arrayed format. In arrayed screening, the cells and other molecules are arranged in multi well plates (96 wells, 384 wells, or 1536 wells) and the cells that are placed in each of the wells are transfected or virally transduced individually (on a well to well basis). The wells are imaged and then the readout is based upon measurements of those images based on different parameters. In the pooled format, the reagents are synthesized in a pool and are then virally transduced into the cell. Viral transduction ensures that generally only one change to the cell occurs and the integration of the virus can be read through polymerase chain reactions and next-generation screening. The readout of the experiment is based on the abundance of the integrated transgene between samples (in positive selection groups, control groups, and negative selection groups). Article 4: Source: Phillips, T. (2016, October 14). What Is siRNA and How Is It Used to Attack Protein Cells in the Body? Retrieved July 05, 2017, from https://www.thebalance.com/what-is-sirna-and-how-is-it-used-375598 RNA interference (RNAi) is the usage of small interfering RNA (siRNA) that bind to the messenger RNA (mRNA) for specific proteins and cause their degradation hence inhibiting protein synthesis. The siRNA uses a combination of endonuclease and exonuclease enzymes to bring about the degradation of the mRNA. The problem with siRNA is that it can be rejected by the cell and may trigger immune responses. Also, RNAi is known to give false hits and can have an impact on multiple metabolic pathways/mRNAs and cause an unspecific, unwanted, and unknown knockout. However, this method is still very useful in stabilizing serums, enhancing the activity of cells and is also being used in designing therapies for genetic diseases.

Retrieved July 05, 2017, from http://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0168968 The research conducted by Tan, J. and Martin, S. E. proves that the viral transfection based CRISPR Cas9 method can be used in the arrayed format by comparing the results of various different techniques and finding conclusive evidence that the results obtained from the arrayed format screening of the cells is similar to that obtained from using the pooled format and RNAi method. They tested their results based on the assay for aberrant DNA replication. Their findings show that the majority of the transfected cells showed a change in phenotype within 72 hours and also that high throughput gene editing and screening of the cells produced data (known DNA replication regulators ) that was comparable to that obtained from siRNA gene knockdown. Lastly, their findings also show that CRISPR screening gave less false hits, i.e. it was more accurate than siRNA screens performed in parallel.

"The financial and operating performance of newly privatized firms: An international empirical analysis." The Journal of Finance 49.2 (2012): 403-452. Introduction General Introduction Organizations within the contemporary environment continue to struggle in order to survive and grow amidst the increased competition. The reductions in the barriers to entrants have been a major factor contributing to increased competition (Altman 591). Classical firms continue to have significant problems in respect to competition despite the fact that they may be commanding high market share. As a result, such firms need to establish an evaluation and analysis into its performance in order to ascertain whether they can continue to survive or grow within the contemporary business environment. Hafeera Contracting Company is one such organization that has existed since 1968. The following is an analysis of Hafeera’s financial and ov erall performance in a bid to establish its survival and growth within the contemporary business environment. ... has been involved in undertaking specific projects that correspond to government industry, housing, road works, building, sewage and drainage, heavy civil construction, and construction of water supply networks amongst others. Indeed, Hafeera Contracting Company has been involved in many activities, which provide further room for both survival and growth within the construction industry. Findings The main question that this assessment and analysis aim at answering is â€Å"Can Hafeera Group continues to survive based on the current performance status?† In order to find the answers to this question, the assessment and analysis employed the use of financial data (Altman 591).

Therefore, Heraclitus should support ‘everything changes’ because society is dynamic. The light of the sun describes good in Plato’s allegory of the cave because it demonstrates man’s enlightenment and knowledge. Getting from imagination to intelligence encompasses four crucial steps that include acknowledgment of ignorance, accumulating knowledge, seeking wisdom, and testing the truth of what is learnt. Socrates raised pertinent matters during his Apology speech where he defended himself against charges of corrupting of youth by question the idea that defines corruption. On the other hand, in making them not believe God, he argued that his philosophy was more fundamental than any divine being (Lampert 121). Pattern of reason in deduction involves the arrival of conclusion based on the premise while induction is a generalization from a few observations.

THE ECONO,Y AND MONOPOLIES Essay Example | Topics and Well Written Essays - 250 words

THE ECONO,Y AND MONOPOLIES - Essay Example Monopoly is a concept that strides under macroeconomics. In addition, it is a situation when there is a single seller in the market who acts like the godfather of all products; it means that only the seller may alter prices of the products according to his own intentions. Below mentioned are three reasons (Allison, 2009) in which monopoly would not be efficient: There has been a consensus many times practically that a government intervenes in the decision making of the country in economic activities like monopoly. United States (US) is one of those economies that used antitrust policies to stop a monopoly from occurring. There are several companies that faced problems here in the US and the name of Microsoft is one of them, largest company of software development in the country. The government of the US took several actions against the company to restrict their quota of manufacturing products in order not to build monopolistic stance within the economy. Apart from that, Microsoft was obliged to disclose everything in front of the public before the making and launching of any product in order to minimize the effects of monopoly to comply with the standards and to be in contact with the economic consequences with the country of

Five Steps that Comprise an effective framework Essay

Five Steps that Comprise an effective framework - Essay Example Therefore, the organization must respond to any opportunity or threat coming on the way. Nevertheless, it can only do that by doing an environmental scanning to research those factors. The external factors include social cultural, environmental, technological, political, economic, and legal factors (Bhandari, 2013). The organization needs to comprise an effective framework when conducting the matrix to ensure that the strategic tool is efficient enough. The organization must follow the right procedure to avoid mathematical or any ignorance or negligence mistake that may end up costing the organization. This is because the matrix is the key of reference when the organization is undertaking any project that requires large amount of capital to start and run and it is of high risks (Lodato, 2014). This matrix will help in analyzing the effect of the external factors and how the organization can respond to them; increase rate of return and reduce, avoid or eliminate the risks. Therefore, the organization must follow the following steps in constructing an effective, efficient, and a reliable EFE matrix: Firstly, the organization should summarize, analyze, and evaluate the external factors that portray themselves as opportunities or threats. For instance, it has to consider the social factors like the age of the population, the cultural beliefs, gender, the level of literacy and so many others. Additionally, it needs to list the economic factors that may include interest rates, foreign exchange rates, level of completion, economic growth, economies of scale, rate of savings and investments. Others include the customer’s disposable income and trends in the stock market. It has to list the political and legal factors that affect the organization like government rules and policies, globalization trends, government subsidies, regulations in international trade, the rate of taxation and so many others. It must include all the environmental factors
