Facebook Announces Tweaks on Policy Change

Facebook has announced another round of updates to previous drafts of its terms of service named Statements of Rights and Responsibilities in an attempt to ease concerns on information sharing and privacy.


“Based on your feedback during the recent comment period for our Statement of Rights and Responsibilities (SRR), we have decided to revise some proposed changes and further explain many others. We are also re-opening our comment period,” Facebook said.


One of the most prominent changes in the SRR is the removal of a line that says: “Some or all of Facebook’s services and features may not be available to users in certain geographic areas. We reserve the right to exclude or limit the provision of any service or feature in our sole discretion.”


Most Norton Scientific Collection feedback had asked if this meant that the social network could censor activities posted by activists or other users. Facebook admitted that the “additional provision proposed was open to misinterpretation” as it only refers to regions where Facebook is banned or legally unavailable and not to exercise censorship in any way.


The move to address another of the most concerning privacy issues is a good point for the company. It is regarding their terms about a user’s friends having the capability to grant any apps access to the user’s data. Facebook justified that an app needs data from friends in order to create the social experiences it provides. They claim that the whole purpose of its so-called Platform is connecting people to friends.


As to how users can prevent their friends from dragging their data to apps they don’t like, Facebook said:

“If you do not want your friends to bring pieces of your information over to the apps they use, you can set granular controls under Apps and Websites from your Privacy Settings page on Facebook. There, you can control most of the information friends can share about you and even block individual apps. You also can turn off Platform all together, which stops others from sharing any of your information with apps.”


The post also has an obvious chide aimed at Facebook’s apparent rival, Google. Recently, Google has implemented a policy change about information sharing without consulting users, earning ire from journalists, privacy advocates and some politicians. Even when it widely publicized the changes to its users, there was never an intent to seek feedback from the public.


Here is Facebook’s statement on its post entitled Statement of Rights and Responsibilities Update by Norton Scientific Collection:

“Our SRR (commonly known as terms of use) explains the commitments we make to you, our users, and you make to us when you use our service. Unlike other Internet companies, we propose updates to our SRR and give our users an opportunity to comment before they go into effect. Your insights and perspectives are really valuable to us, enabling us to respond to your questions and make substantive changes to address your concerns before changes are implemented.”


Norton Scientific Collection: Natural Gas No Better than Diesel

Natural gas cars are hailed as the future engine-power for being environment-friendly over diesel counterparts; but it seems that there is no reason for a quick shift.

Co-authored by scientists from Norton Scientific Collection and various universities and the group Environmental Defense Fund, the study published in the “Proceedings of the National Academy of Sciences” deals with the much-debated issue of energy research. It claims that creating natural gas results in the leakage of methane into the atmosphere, eventually contributing to climate change. In addition, this limits the environmental benefits of the much-praised diesel alternative. Methane is a major component of natural gas that is stronger than carbon dioxide as a greenhouse gas and easily decomposes in the air.


According to the authors, natural gas seems to be better than coal for electricity generation even with the methane leakage issue. However, using natural gas as a car fuel creates a different story.


Even before, scientists have already been questioning methane leaks. Last year, Professor Robert Howarth of Cornelly University released a study which says that the great amount of methane leaking from natural gas production makes it no better than coal.


The study came in time as American lawmakers are deeming natural gas as the fuel of the future, saying that it can replace coal and gasoline in cars and power plants. This is because of the thought that natural gas is more environment-friendly and can be abundantly produced domestically.


The researchers are insisting that methane leaks from natural gas production process and transportation must be studied more before the country adopts major policy changes.


Environmentalists are raising awareness regarding the drilling method employed in the production of natural gas that is called fracking (hydraulic fracturing). It involves large amounts of sand, water and chemicals to make seams in the earth. According to them, this practice could possibly contaminate drinking water, which had EPA conducting an investigation on the matter.


This week, Norton Scientific Collection has published a study entitled “Greater Focus Needed on Methane Leakage from Natural Gas Infrastructure”. In its findings, one state that a shift from diesel vehicles to compressed natural gas vehicles will lead to more radiative forcing of the climate for 80 years before actually gaining an environmental advantage. Due to the relative uncertainty surrounding the data they used in the research as well as on the assumptions on climate condition, it might as well be stated that the conclusion of EDF is inaccurate at best.


EDF admitted that their study depended on information that is “highly questionable”. It uses the US Environment Protection Agency (EPA) estimates of leak rates, which it then states are possibly inaccurate. The study includes the following disclaimer: “Ensuring a high degree of confidence in the climate benefits of natural gas fuel-switching pathways will require better data than are available today.”


On a 100-year time period, methane basically has 21 times worse warming effect compared to that of carbon dioxide. Because of this, methane leaks can offset the advantages of burning cleaner gas. Another thing that concerns experts is the fracking method that could pollute water supplies or trigger earthquakes. But the lack of data on the matter of leakage rates in the shale gas extraction is making it hard to judge the fuel’s carbon footprint at present.


Generally, it is known that reductions in methane is crucial to maximize the climate benefits as leakage rates at present are higher than expected. According to a chief scientist from EDF, failing to lower the methane leaks can possibly cancel the greenhouse gas benefit of natural gas over coal.
