Earlier this month, Wikinews spoke with University of Sussex professor of economics L. Alan Winters regarding the decision of the United Kingdom to leave the European Union (EU) in the 2016 Brexit referendum and the subsequent negotiations leading up to and following the EU–UK Trade and Cooperation Agreement of December, which he has researched extensively. In a call, a Wikinews correspondent spoke with Professor Winters about recent developments in UK trade policy to learn more about his observations.

Winters is professor of economics at the University of Sussex, as well as founding director and fellow of the UK Trade Policy Observatory (UKTPO). His career spans over 15 years, including as chief economist at the Department for International Development, director of the Development Research Group of the World Bank, CEO of the Migrating Out of Poverty Research Programme Consortium and advisor for the Organisation for Economic Co-operation and Development, the Commonwealth Secretariat, the European Commission, the European Parliament, the United Nations Conference on Trade and Development, the World Trade Organization and the Inter-American Development Bank.

Three reports where Winters is listed as an author were used as reference during the interview: “COVID-19 will reinforce the Brexit shock”, “The Costs of Brexit” and “Taking stock of the new UK-EU Trade and Cooperation Agreement: governance, state subsidies and the level playing field”.

Winters was awarded the title “Companion of the Most Honourable Order of the Bath”, styled C.B., on June 16, 2012 as part of the 2012 Birthday Honours.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

A diverse group of approximately 25 people gathered at the Johnson County Library on Monday to participate in reference librarian Scott Vieira’s class, Wikiwhatia? Wikipedia.

Scott opened the session by sharing a disparaging quote from Robert McHenry (former editor-in-chief of Encyclopedia Britannica) comparing Wikipedia to a public restroom. He then shared a quote from Andrew Keen, author of The Cult of the Amateur, in which he stated Wikipedia is the blind leading the blind. Scott shared Wikipedia usage data from a 2007 Pew Internet study showing 36% of adults have consulted Wikipedia and that that Wikipedia receives 10,000-30,000 searches per second. Scott also pointed out that Wikipedia now has over two million articles in English alone (over nine million articles in 250 languages). So there is a discrepancy here, lots of critics and lots of use.

Scott then shared some historical information in order to provide a context for understanding Wikipedia. This included some important names and dates in the history of encyclopedias… including Pliny the Elder (23-79 C.E.) who published 37 Volumes of Natural History, and Joachim Sterck van Ringelbergh (c. 1499-1556) who first used the term encyclopedia, and then d’Alembert and Diderot who published 17 volumes of their French Encyclopedia from 1751-1765. Encyclopedia Britannica was first published in Scotland in serial format 1768-1771.

Scott also discussed more recent history, sharing a photo of Ward Cunningham –who is credited with being the inventor of wiki software. Wikipedia was founded on Jan 15, 2001 by Larry Sanger and Jimmy Wales. Sanger left Wikipedia in 2002 and founded Citizendium in 2007 a complementary project which now has 4500 articles.

After the historical perspective, the class moved into using Wikipedia. Everyone in the audience had used Wikipedia. The class explored the content of Wikipedia, realising there is a whole lot going on. Scott demonstrated that the article about “frogs” for example, is semi-protected. The “history of science” article was examined, including the history of changes. Discussion covered how people contribute, who contributes and edits. The group also talked about Wikipedia bots, which aid in routine tasks in a semi-automated or automated fashion.

A discussion about teachers, school media specialists and students regarding their use of Wikipedia ensued. Some teachers and school media specialists are negative about Wikipedia, but Scott’s hope is that they will use it to start a discussion about the need to evaluate and critically think about information (even when it’s from more traditionally reviewed and edited sources).

An unanswered question from an audience member was, “What was the first Wikipedia article?”

Discussion topics from Scott to audience were as follows:

• Do you think Wikipedia is less accurate than published resources and how important is that accuracy to you?
• How do we determine authority on a subject? How important is it that an article be written by an expert? How is Wikipedia changing our idea of what an authority is?
• Currency – the ability to publish immediately – what are the advantages and what are the disadvantages?
• What do we think about the content selection in Wikipedia?
• Should Wikipedia be used by librarians?
• What do you think about the future of Wikipedia?

The battle between the two high definition optical disc formats, Blu-ray and HD DVD has ended after sole HD DVD manufacturer Toshiba has announced it will no longer produce HD DVD players.

In a press conference yesterday, Toshiba president Atsutoshi Nishida announced and confirmed that Toshiba will terminate the R&D plan on HD-DVD products. The key issue to force Toshiba terminating their HD-DVD R&D plan was Warner Bros., who changed their R&D plan from HD-DVD to Blu-ray on January 4.

In what is a reverse of the VHS vs Betamax format war, Sony‘s Blu-ray has come out on top with the backing of major studios and retailers such as Warner Bros. but also Wal-Mart, Best Buy, Netflix, and Blockbuster who announced they would only support Blu-ray exclusively this past month.

Even though Toshiba is currently about to change their R&D plan from HD-DVD to NAND flash drives and micro drives and plan to build two factories in Iwate, Japan, the company will provide the maintenance service on discs and players in the future 8 years.

Sony bundled Blu-ray into their PlayStation 3 game system. Microsoft’s competing Xbox 360, comes with a $200 HD DVD add-on player, whose fate is now undetermined with the demise of HD DVD. Microsoft has said they will wait for what Toshiba has to say.

An HIV-positive man was sentenced to 35 years in prison Wednesday, one day after being convicted of harassment of a public servant for spitting into the eye and open mouth of a Dallas, Texas police officer in May 2006. The United States Centers for Disease Control and Prevention says that no one has ever contracted HIV from saliva, and a gay-rights and AIDS advocacy group called the sentence excessive.

A Dallas County jury concluded that Willie Campbell’s act of spitting on policeman Dan Waller in 2006 constituted the use of his saliva as a deadly weapon. The incident occurred while Campbell, 42, was resisting arrest while being taken into custody for public intoxication.

“He turns and spits. He hits me in the eye and mouth. Then he told me he has AIDS. I immediately began looking for something to flush my eyes with,” said Waller to The Dallas Morning News.

Officer Waller responded after a bystander reported seeing an unconscious male lying outside a building. Dallas County prosecutors stated that Campbell attempted to fight paramedics and kicked the police officer who arrested him for public intoxication.

Prosecutors said that Campbell yelled that he was innocent during the trial, and claimed a police officer was lying. Campbell’s lawyer Russell Heinrichs said that because he had a history of convictions including similarly attacking two other police officers, biting inmates, and other offenses, he was indicted under a habitual offender statute. The statute increased his minimum sentence to 25 years in prison. Because the jury ruled that Campbell’s saliva was used as a deadly weapon, he will not be eligible for parole until completing at least half his sentence.

The organization Lambda Legal (Lambda Legal Defense and Education Fund), which advocates for individuals living with HIV, says that saliva should not be considered a deadly weapon. Bebe Anderson, the HIV projects director at Lambda Legal, spoke with The Dallas Morning News about the sentence. “It’s been 25 years since the virus was identified, but there are still lots of fears,” said Anderson.

The Dallas County prosecutor who handled the trial, Jenni Morse, said that the deadly weapon finding was justified. “No matter how minuscule, there is some risk. That means there is the possibility of causing serious bodily injury or death,” said Morse. Dallas County District Attorney Craig Watkins stated: “If you look at the facts of this case, it was clear that the defendant intended to cause serious bodily injury.”

A page at the CDC’s website, HIV and Its Transmission, states: “HIV has been found in saliva and tears in very low quantities from some AIDS patients.” The subsection “Saliva, Tears, and Sweat” concludes that: “Contact with saliva, tears, or sweat has never been shown to result in transmission of HIV.” On Friday the Dallas County Health Department released a statement explaining that HIV is most commonly spread through sexual contact, sharing needles, or transfusion from an infected blood product.
