Job Prospects in Social Media and Civil Engineering

http://www.indeed.com is a job search engine that has a fairly good traffic as shown by the following chart


Social Media is an emerging area and many jobs are opening in this area. A comparison of job openings in the area of "Social Media" and "Civil Engineering" is done using the indeed search engine and shown in the picture below

Click on the image for a larger view



What is interesting is that there are more jobs in the area of "Social Media" as compared to the jobs in Civil Engineering even though it is a fairly new area that did not exists few years ago. The lower end jobs pay better in Civil Engineering but there are fewer high paying jobs.

Also the two key words "Civil Engineering" and "Civil Engineer" leads to different search results as shown by column 2 and column 3 of the figure. This shows that the search results are sensitive to the choice of key words even though the two keywords are nearly identical.

Social Networking : Current Limitations and Future Possibilities

The Real Life Social Network" presentation by Paul Adams The Real Life Social Network v2
View more documents from Paul Adams.
Paul Adams, a senior user experience researcher at Google (NSDQ: GOOG), is leaving the company to join Facebook starting next year, according to Inside Facebook and one ofhis tweets. He may be best known for his deep analysis of Facebook and its privacy issues in a lengthy presentation five months ago. In particular, “The Real Life Social Network” pointed out how the site doesn’t enable users to manage the various kinds of relationships within their greater network of friends.
The presentation highlights the limitations of the current social networking software in mapping the real life relationships. The key assumption here is that the social networking software should accurately map the real life relationships. The presentation suggests to use the work of anthropologist Robin Dunbar as a guideline in designing the social networking software.
Dunbar's number is a theoretical cognitive limit to the number of people with whom one can maintain stable social relationships. These are relationships in which an individual knows who each person is, and how each person relates to every other person.[1] Proponents assert that numbers larger than this generally require more restrictive rules, laws, and enforced norms to maintain a stable, cohesive group. No precise value has been proposed for Dunbar's number. It lies between 100 and 230, but a commonly used value is 150.[2]
Source
The idea is that there is a cognitive limit and on the average we can maintain and manage around 150 relationships.
Every new technology starts out as copying some human capability. In this case social networking software is mimicking the human relationships. However, as the new technology matures it takes a new form and extends the existing human capability. The example would be a car. It extends our ability to move faster but it uses wheels to do it not something similar to legs. In the case of social networking software the possible scenario would be that it extends our cognitive limit to manage relationships that will allow us to manage relationships beyond the average number of 150 set as a limit by the research work of Robin Dunbar.
The author has down played the role of weak ties. It is true that we spend most of our time managing strong ties but the research work of Granovetter shows the usefulness of weak ties in getting a job and diffusion of information through the a populace.

Source

The last line of this abstract shows the importance of the weak ties. These are the ties that allow the information dissemination between groups that are locked within themselves. In some instances they are more important than the strong ties.

Granovetter’s work (1973) proved to be crucial in the individualistic approach of the social network theory as seen by the amount of references in other papers. His argument asserts that weak ties (acquaintances, according to Granovetter, 1973; 1983) are less likely to be involved within the social network than strong ties (close friends and family). By not going further in the strong ties, but focusing on the weak ties, Granovetter highlights the importance of acquaintances in social networks. He argues, that the only thing that can connect two social networks with strong ties is a weak tie: “… these clumps / [strong ties networks] would not, in fact, be connected to one another at all were it not for the existence of weak ties. (Granovetter, 1973 pp 1363; 1983 pp 202).

It follows that in an all-covering social network individuals are disadvantageous with a few weak links compared to individuals with multiple weak links as they are disconnected with the other parts of the network. Another interesting observation that Granovetter makes in his work is the fact of forth going specialization of individuals creates the necessity for weak ties as all the other specialist information and knowledge is present in other social networks (Granovetter, 1973).

source


Although the current policies of facebook, a popular social networking site favors friending based upon strong ties. However, in the future the social networking will be a software platform that extends our cognitive limit beyond the manageable relationships of 150 and places more emphasis on weak ties that allow us to escape our current group and let us explore new kinds of relationships that enriches our life experiences.

Google Books Ngram Viewer on Men vs. Women, Media , and STEM

Google labs recently released a Books Ngram Viewer. It is available here. The ngram allows to serach for words and phrases that could be five word long within books data base dating back to 1800. The data base contains 12 percent of all published books but it is substantial and can be used to investigate cultural trends.

More details about the methodology are published in the research paper titled "Quantitative Analysis of Culture Using Millions of Digitized Books"

The Abstract

We constructed a corpus of digitized texts containing about 4% of all books ever printed. Analysis of this corpus enables us to investigate cultural trends quantitatively. We survey the vast terrain of “culturomics”, focusing on linguistic and cultural phenomena that were reflected in the English language between 1800 and 2000. We show how this approach can provide insights about fields as diverse as lexicography, the evolution of grammar, collective memory, the adoption of technology, the pursuit of fame, censorship, and historical epidemiology. “Culturomics” extends the boundaries of rigorous quantitative inquiry to a wide array of new phenomena spanning the social sciences and the humanities.
The paper can be accessed here

Men vs Women

The first trend was to see how the words men and women faired over the year. The plot is shown below

Please click on the image for an enlarged view



The plot starts from 1800 and is fairly constant for men till 1880. After that it start losing and the plot for women start gaining. It picks up steam around 1970 and crosses over around 1990 and takes over.

It shows steady ascendancy of women in the last century and finally taking over. This period also roughly coincides with the start of feminist movement and a decline in patriarchal value system.

It shows that the grass root efforts of feminist movement with lots of organizing and field work paid off in the end.

The next plot was created for the trend in different media such as print, radio, movie, TV and Internet. The plot is shown below


Please click on the image for an enlarged view


No surprises here. Print was dominant media type and pretty stays the same through 1800-2000. Radio had a phenomenal rise and still dominates that is surprising. The possibility is that Radio is identified with wireless communication and even though Radio is not as big as TV but wireless communication is still a big part of communication landscape. Movies enjoyed a steady rise but over shadowed by TV around 1950. TV took over print media around 1980. Since then TV has been on an upward trajectory. What is surprising is that Internet as a media is just a short blip showing at the bottom right of this plot. It really is not part of mainstream media and still have long way to go. Other possibility is that Internet is not a single media type and one has to add contribution of words like "New Media", "Interactive Media" and "social Media" etc. I mean it is clear that Internet according to chart has to acquire an identity that is competitive with other four media type.

The last trend chart was created to see the trend for Science, Mathematics, Engineerings and Technology. There is a big push in academic circles these days to integrate Science, Mathematics, Engineering and Technology ( STEM) in a single unit to achieve synergistic effect of these four disciplines with the support from National Science Foundation. On the surface they all appear to be same and seems to work on the same type of problems. However, these four discipline have different historical origins and have different professional practices that emphasizes different aspects of the same problems occurring in nature.

The chart is shown below


Please click on the image for an enlarged view



Looking at the plot it is obvious that Science has been on a steady rise since 1800. Mathematics has been around and has a steady trend. Engineering took off around 1890 and steadily gained since then. However Technology that is older then Science historically started gaining around 1960 and took over Engineering around 1970.

These trends are approximate but corroborate well with the existing knowledge of the trends about the topics.

Fun, Happiness, Science and Technology | Google Books Ngram Viewer

Google labs released "Google Books Ngram Viewer". It is build using the data from 15 million scanned books.

"The datasets we're making available today to further humanities research are based on a subset of that corpus, weighing in at 500 billion words from 5.2 million books in Chinese, English, French, German, Russian, and Spanish. The datasets contain phrases of up to five words with counts of how often they occurred in each year. (...) The Ngram Viewer lets you graph and compare phrases from these datasets over time, showing how their usage has waxed and waned over the years," says Jon Orwant, from the Google Books team. Source

Here is a simple experiment using four words Fun, Happiness, Science and Technology

Click on the image for an enlarged view

A very interesting pattern emerges. Between years 1700-1800 word Fun appears a lot in the books. It dominates heavily the other three words. After 1800 the use of word Happiness takes off while fun drops offs sharply. At the same time the use of word science starts taking off. Around 1850 a cross over occurs where Happiness start tapering off while Science start moving up. While all this is happening Technology is nowhere on the radar. Between 1900 and 2000 fun and happiness takes a back seat to Science and Technology. Technology picks up around 1950 while Science keeps moving in an upward trend.

These trends are very interesting. They point towards the fact that Science and Technology are antithesis of Fun and Happiness. Emergence of these two has followed by a decrease in Fun and Happiness. This trend is contrary to the accepted wisdom that more Science and Technology will improve the quality of life leading to more fun and happiness. It also raises a question: Are we really happier than our ancestors?

Indian Institute of Technology | Premier Engineering Education Institutions in India | IIT | Revised Version

India is a large diverse country with world's second largest population over one billion people. It is also home to some of the best Engineering schools.
These schools have very hard admission requirement and a very rigorous Engineering curriculum.

They were established as independent institution of higher learning for Science and Engineering
The Indian Institutes of Technology (IITs), are a group of fifteen autonomous engineering and technology-oriented institutes of higher education established and declared as Institutes of National Importance by the Parliament of India. The IITs were created to train scientists and engineers, with the aim of developing a skilled workforce to support the economic and social development of India after independence in 1947. The students and alumni of IITs are colloquially referred to as IITians.

It is clear from this table that original five were established between year 1950 and 1961. There was a major expansion in the last ten years and the last nine of them were established between years 2000-2009. There is one more in making that will be located at Varanasi, Uttar Pradesh.

Each IIT is an autonomous university, linked to the others through a common IIT Council, which oversees their administration. They have a common admission process for undergraduate admissions, using the Joint Entrance Examination (popularly known as IIT-JEE) to select around 4,000 undergraduate candidates a year. Postgraduate Admissions are done on the basis of the GATE, JMET, JAM and CEED. About 15,500 undergraduate and 12,000 graduate students study in the IITs, in addition to research scholars. Source

The graduates from these sister institutions in general have done well locally in India as well as internationally with US as being one of the main destination.
IIT alumni have achieved success in a variety of professions.[2] Owing to the autonomy of the IITs, these institutes are among those few institutes (the other institutes being National Institutes of Technology or the NITs) in India that offer degrees in technology (B. Tech.) at the undergraduate level as opposed to the Bachelor of Engineering (BE) degrees awarded by most other Indian universities. Most of the IITs were created in early 1950s and 1960s as the Institutes of National Importance through special acts of Indian Parliament. The success of the IITs led to the creation of the Indian Institutes of Information Technology (IIIT) in the late 1990s and in the 2000s. Source

World's Fastest Bullet Train

Details about the train
"We are now much faster," Railway Ministry spokesman Wang Yongping said at Tuesday's inauguration of the super-fast line from Shanghai's western suburb of Hongqiao to the resort city of Hangzhou. "Now other countries are hoping to cooperate with us."

The train will cruise at a top speed of 220 mph (350 kph), making the 125-mile (200-kilometer) trip in 45 minutes.

China already has the world's longest high-speed rail network and aims to more than double its length to 10,000 miles (16,000 kilometers) by 2020.

The high-speed bullet train in China can actually reach speeds of up to 260 mph.

REVIEW | Samsung Fascinate Mobile Phone Sound and Camcorder Application

Android "Voice recorder" application could be used to record sound on the phone.The screen capture of voice recorder app and Pandora app for music on the phone is shown below








A sound recording was made using the voice recorder of the music playing on the Pandora application.





Another slightly longer recording example is here




Samsung Fascinate allows good quality sound recording by using simple "Voice Recording" application.

Samsung Fascinate also includes an excellent Camcorder function as part of Camera application that allows video recording at multiple resolutions with several useful settings to improve the video quality.

The complete video recording application's menu details are shown in the picture below

From SAmsung Fascinate Miscellaneous Pictures


The videos can be recorded in five different resolutions as shown in the image above. Other useful adjustments to the video recording can be made by selecting some of the menu items shown in the picture.

Higher resolution recording improves the readability of the screen test.

These recordings show a good quality video recording. They show that Samsung Fascinate can be used make decent computer screen copies. As expected computer screen text is more readable in higher resolution video.

Here is another example where an advertisement for jeans showing Megan Fox was played on the computer screen and it was recorded in two different resolutions

Again both videos show good quality recording with higher resolution video having a slight edge. What however is interesting is that it allows to create copies of videos directly from computer display saving some complicated steps to screen capture a video.

The above examples show that Samsung Fascinate mobile phone can create high quality audio and video content. Just for this reason alone the phone is highly recommended.
