The literature on judgment aggregation is moving from studying impossibility results regarding aggregation rules towards studying specific judgment aggregation rules. Here we give a structured list of most rules that have been proposed and studied recently in the literature, together with various properties of such rules. We first focus on the majority-preservation property, which generalizes Condorcet-consistency, and identify which of the rules satisfy it. We study the inclusion relationships that hold between the rules. Finally, we consider two forms of unanimity, monotonicity, homogeneity, and reinforcement, and we identify which of the rules satisfy these properties.

They are the APAC and Australian leaders of some of the largest, or fastest rising marketing tech, adtech and ecommerce companies. And they are passionate about helping their clients understand their own consumers using data analytics. So we figured it was time to turn the lens around. We used IBM's Personality Insight services in the Watson Developer Cloud to tell us a little bit about the personality of each of the following executives; Karen Stocks from Twitter, Ben Sharp from AdRoll, Liam Walsh from Amobee, Jodie Sangster from ADMA, Paul Robson from Adobe, Derek Laney from Salesforce, Paul Cross from Oracle, Matt Barrie from Freelancer and Ruslan Kogan from Kogan. Given their commitment to the cause of data-driven marketing we are sure they won't mind at bit.

The Pentagon's oft-repeated line on artificial intelligence is this: we need much more of it, and quickly, in order to help humans and machines work better alongside one another. But a survey of existing weapons finds that the U.S. military more commonly uses AI not to help but to replace human operators, and, increasingly, human decision making. The report from the Elon Musk-funded Future of Life Institute does not forecast Terminators capable of high-level reasoning. At their smartest, our most advanced artificially intelligent weapons are still operating at the level of insects … armed with very real and dangerous stingers. So where does AI exist most commonly on military weapons?

All those cars on California's famously gridlocked highways could be doing more than using energy. They could be producing it. The California Energy Commission is investing 2 million to study whether piezoelectric crystals can be used to produce electricity from the mechanical energy created by vehicles driving on roads. The commission is choosing a company or university to take on small-scale field tests. It will study how the small crystals, which generate energy when compressed, could produce electricity for the grid if installed under asphalt.

In the Summer of 2015 a team of hackers attempted to take control of an unmanned military helicopter known as Little Bird. The helicopter, which is similar to the piloted version long-favored for US special operations missions, was stationed at a Boeing facility in Arizona. The hackers had a head start: At the time they began the operation, they already had access to one part of the drone's computer system. From there, all they needed to do was hack into Little Bird's onboard flight-control computer, and the drone was theirs. When the project started, a "Red Team" of hackers could have taken over the helicopter almost as easily as it could break into your home Wi-Fi. But in the intervening months, engineers from the Defense Advanced Research Projects Agency had implemented a new kind of security mechanism--a software system that couldn't be commandeered.

Taban Deng Gai, who is now first vice president of South Sudan, speaks to reporters in Ethiopia's capital Addis Ababa on Jan. 8, 2014. In an interview airing on Monday's PBS NewsHour, South Sudan Vice President Taban Deng Gai responded to a report that the country's top leaders were profiting off the five-year conflict by saying it's under investigation, but the report might be false. Human rights group The Sentry this month released the results of a two-year investigation that found South Sudanese politicians were spending international aid on mansions and fancy cars, and giving expensive contracts to family members. "They say that my president, for example, they accuse him of having a house in one of the suburbs of Nairobi city. I don't think a crime for a president -- a sitting president for more than 10 years" to have a house there, Deng told PBS NewsHour Weekend anchor Hari Sreenivasan.

In order to safeguard humanity, the single most important thing we must do will be to teach concepts of rights and values -- to machines. For instance, Stephen Hawking has said that "success in creating AI would be the biggest event in human history...Unfortunately, it might also be the last, unless we learn how to avoid the risks." Hawking thus believes that the "development of full artificial intelligence could spell the end of the human race." Elon Musk has called the prospect of artificial intelligence "our greatest existential threat" and thinks that AI weaponry could pose an even bigger threat than nuclear warfare, which is why he supports regulatory oversight of AI. However, in the recent Stanford Report, "The Study Panel's consensus is that attempts to regulate'AI' in general would be misguided, since there is no clear definition of AI (it isn't any one thing), and the risks and considerations are very different in different domains."

It's just the way it is: the human being is a lazy creature. If it's possible not to do something, we don't do it. However, paradoxically this is a good thing, because laziness is… the engine of progress! Well, if a job's considered too hard or long-winded or complex for humans to do, certain lazy (but conscientious) humans (Homo Laziens?:) give the job to a machine! In cybersecurity we call it optimization.

Physicists at the Australian National University (ANU) have successfully completed an experiment to stop light, similar to the way Kylo Ren used the force to stop a laser blast. Jesse Everett from the Research School of Physics and Engineering (RSPE) and Australian Research Council (ARC) Centre of Excellence for Quantum Computation and Communication Technology at ANU, said controlling the movement of light was a critical step in developing future quantum computers. "Optical quantum computing is still a long way off, but our successful experiment to stop light gets us further along the road," Everett said. "It's pretty amazing to look at a sci-fi movie and say we actually did something that's a bit like that." Everett said quantum computers based on light could connect easily with communication technology such as optic fibres and had potential applications in fields such as medicine, defence, telecommunications, and financial services.

Forget self-driving cars, soon you could be travelling around the city in self-driving drones. The taxi-finding app Uber is researching the plausibility of using vertical takeoff aircraft to fly its customers around cities. The technology could be available within a decade, according to Jeff Holden, head of products at Uber. Forget self-driving cars, soon you could be travelling around a city in self-driving drones. Artist's concept of a vertical takeoff and landing (VTOL) aircraft being developed by Aurora Flight Sciences for the US military is shown Jeff Holden, head of products at Uber told Recode he has been researching the idea of self-driving drones, so the company'can someday offer our customers as many options as possible to move around.' Mr Holden said landing on top of buildings in cities would help reduce commuting time and congestion dramatically.
