Crystal structure of 1,10-phenanthrolinium violurate violuric acid pentahydrate

The title compound [systematic name: 1,10-phenanthrolinium 6-hydroxy-5-(oxidoimino)-1,3-diazinane-2,4-dione–6-hydroxy-5-(hydroxyimino)-1,3-diazinane-2,4-dione–water (1/1/5)], C12H9N2+·C4H2N3O4−·C4H3N3O4·5H2O, is a co-crystal salt hydrate comprising 1,10-phenanthrolinium cations, violurate anions, free violuric acid as co-former and five water molecules of crystallization per formula unit. The violurate and the violuric acid residues each form distinct N—H...O hydrogen-bonded tapes with a common R22(8) hydrogen-bond motif extending parallel to (103). Solvent water molecules connect the tapes to form a tri-periodic hydrogen-bonded network with channels extending parallel to the a-axis direction, which accommodate the N—H...Owater hydrogen-bonded 1,10-phenanthrolinium cations. Direct N—H...O hydrogen bonds between the 1,10-phenanthrolinium and violurate ions are not encountered.

LA and the $15 minimum wage: It all started accidentally at a Washington airport

Ben Bergman

As Los Angeles mulls a law that would raise the minimum wage above the current California minimum of $9 an hour, it's the latest city to jump on a trend that started as the by-product of a failed labor negotiation in the state of Washington.

The first city to enact a $15-per-hour minimum wage was SeaTac, Wash., — a tiny airport town outside Seattle. "SeaTac will be viewed someday as the vanguard, as the place where the fight started," the lead organizer of SeaTac's $15 campaign, David Rolf, told supporters in November 2013 after a ballot measure there barely passed.

Rolf never set out to raise SeaTac’s minimum wage, much less start a national movement. Speaking from a sparse corner office in downtown Seattle at the Service Employees International Union 775, which he founded in 2002, Rolf told KPCC that his original goal in 2010 was to unionize workers at SeaTac airport.

When employers – led by Alaska Airlines — played hardball, Rolf put the $15 minimum wage on the ballot as leverage. “We had some polling in SeaTac that it could pass, but it was not at all definitive,” Rolf said.

That proved prescient: In a city of just 12,108 registered voters, Rolf's staff signed up around 1,000 new voters, many of them immigrants who had never cast a ballot. The measure won by just 77 votes.

It's an irony that the new law doesn't apply to workers at the center of the minimum wage campaign: The airport workers at SeaTac. That's because the Port of Seattle, which oversees the airport, challenged the initiative, arguing that the city's new minimum wage should not apply to the nearly 5,000 workers at the airport. A county judge agreed. Supporters of the $15 wage have appealed.

Still, Rolf said, "I think people are proud that that’s what happening. There are leaders of the movement in Seattle, including our mayor, that said shortly after the victory, 'Now we have to take it everywhere else.'"

The $15 minimum wage spread to Seattle last June and to San Francisco in November. 

Why $15 an hour?

The $15 figure first came to people’s attention in a series of strikes by fast food workers that started two years ago in New York. 

“I think it’s aspirational, and it provides a clean and easy-to-understand number," Rolf said. "You can debate whether it ought to really be $14.89 or $17.12, and based upon the cost of living in different cities, you could have a different answer. But in the late 19th and early 20th century, American workers didn’t rally for 7.9 or 8.1 hour working day. They rallied for an eight-hour day.”

“What’s really remarkable about social protest movements in American history is that the radical ideas of one group are often the common sense ideas of another group in a matter of a few years," said Peter Dreier, professor of politics at Occidental College.

Rolf is hopeful the $15 minimum wage can spread to every state. But Nelson Lichtenstein, Director of the Center for the Study of Work, Labor and Democracy at the University of California, Santa Barbara, is skeptical.

“I don’t think having high wages in a few cities will mean it will spread to red state America,” he said. 

Lichtenstein said cities like L.A. have become more labor friendly, thanks largely to an influx of immigrants, but that’s not the case in the South. Oklahoma recently banned any city from setting its own minimum wage, joining at least 12 other states with similar laws, according to Paul Sonn, general counsel and program director at the National Employment Law Project.

In November, voters in four Republican-leaning states — Alaska, Arkansas, South Dakota, and Nebraska — approved higher minimum wages, but they weren’t close to $15.

A $15 dollar wage would have a much greater impact in Los Angeles than Seattle or San Francisco because the average income here is much lower than in those cities. Post-recession, income inequality has become much more of a concern for voters, which has made $15 more palatable, Sonn said.

This fall, the Los Angeles City Council enacted a $15.37 minimum wage for hotel workers that takes effect next year. A similar law has been in effect around LAX since 2007. 

But even though California cities have been allowed to set their own minimum wages for more than a decade, L.A. has never come close to doing so.

Until now.

ODIHR Director Link and IHRA Chair Constantinescu, on day to commemorate genocide against Roma and Sinti, say greater efforts needed to protect endangered memorial sites and ensure dignity of victims

WARSAW / BUCHAREST, 2 August 2016 – Michael Georg Link, Director of the OSCE Office for Democratic Institutions and Human Rights (ODIHR) and Ambassador Mihnea Constantinescu, Chair of the International Holocaust Remembrance Alliance (IHRA), called today for greater efforts to protect endangered memorial sites related to the Roma and Sinti genocide during World War II.

Speaking on the occasion of the commemoration of the liquidation of the “Gypsy family camp” at Auschwitz-Birkenau in 1944, when the close to 3,000 remaining Roma and Sinti in the camp were murdered, they stressed that states have to do more to demonstrate their sincere and strong commitment to education about and remembrance of the genocide.

“Positively, we have seen increasing attention in recent years on the part of OSCE participating States to commemorate the Roma and Sinti genocide, and to educate people about this horrible event. This practice and these experiences should be widely shared and replicated,” Director Link said. “Promoting understanding of the Holocaust and its effect on different communities can help to create empathy and promote equality and non-discrimination for all.”

“Accurate and ethical education about the Holocaust includes the respectful and dignified preservation of memorial sites,” said Ambassador Constantinescu. “States have to take resolute action to protect endangered memorial sites and continue to do more to commemorate the Roma and Sinti victims. The history of these endangered sites should be included as part of broader efforts to educate about the consequences of indifference to racism.”

They called on governments to ensure that endangered memorial sites for Roma and Sinti victims are preserved and protected, to include this history as an integral part of civic and human rights education in their countries. They stressed that current developments, including a disturbing rise in xenophobic public rhetoric and racism, mean it is even more essential to build strong alliances among different communities.

In 2003, with the Action Plan on Improving the Situation of Roma and Sinti within the OSCE Area, the OSCE participating States committed themselves to strengthen education about the Roma and Sinti genocide. Through its Contact Point for Roma and Sinti Issues, ODIHR promotes knowledge about and recognition of the plight of Roma and Sinti during the Holocaust to counter present-day discrimination and racism, and to promote tolerance. According to ODIHR’s recent publication Teaching about and Commemorating the Roma and Sinti Genocide: Practices within the OSCE Area, seven OSCE participating States officially commemorate the Roma and Sinti genocide on 2 August, while a larger number of states commemorate the Roma and Sinti victims on the International Holocaust Memorial Day, 27 January.

The International Holocaust Remembrance Alliance is an inter-governmental organization and the foremost international network of political leaders and professionals advancing and shaping Holocaust education, remembrance and research. Its 31 member countries are committed to the tenets of the Stockholm Declaration. The IHRA Committee on the Genocide of the Roma aims to increase the commitment of IHRA Member Countries to educate, research and commemorate the genocide of the Roma.

OSCE Representative condemns incidents directed at journalists and independent voices in Bosnia and Herzegovina

VIENNA, 29 July 2016 – Continuing intimidation and violence against journalists and independent voices is unacceptable and could further weaken media freedom and freedom of expression in Bosnia and Herzegovina (BiH), Dunja Mijatović, OSCE Representative on Freedom of the Media, said today.

“I am following with great concern the extremely worrying situation in the country which could lead to self-censorship,” Mijatović said. “People engaged in investigative reporting and expressing different opinions, even provocative ones, should play a legitimate part in a healthy debate and their voices should not be restricted.”

Mijatović noted that the latest events open a very worrying chapter on the safety of journalists.

They include:

• Verbal attacks on writer and journalist Nenad Veličković;

• Verbal attacks on Borka Rudić, General Secretary of the Association of BiH Journalists; • Verbal threats on journalist Mirjana Radanović;

• Threats and insults against journalists of FTV Mreža magazine;

• Threats against Dragiša Sikimić, editor-in-chief and the owner of the web portal MojaHercegovina.info;

• Verbal and physical assaults on BN TV, ATV and HIT TV crews;

• A physical attack on a BN TV camera operator; • An assault on Nermin Bisa, editor-in-chief of 24sata.info;

• Verbal threats against freelance journalist Vuk Bačanović; and

• Offensive and discriminatory verbal attacks on Selma Učanbarlić, a journalist from the Centre for Investigative Reporting.

“This trend needs to be immediately reversed. Public condemnation at the highest level is needed in order to send a clear message that such threats, including hate speech, against journalists, academics and writers are not tolerated in a democratic society,” Mijatović said. “Investigations into these incidents, which include death threats transmitted by social media, need to be commenced immediately.”

The OSCE Representative on Freedom of the Media observes media developments in all 57 OSCE participating States. She provides early warning on violations of freedom of expression and media freedom and promotes full compliance with OSCE media freedom commitments.

OSCE/ODIHR Director concerned about reported rise of hate incidents in the United Kingdom, supports calls for tolerance in a challenging time

WARSAW, 30 June 2016 – Michael Georg Link, Director of the OSCE Office for Democratic Institutions and Human Rights (ODIHR), expressed his concern following the rise in hate incidents reported to the police in the United Kingdom following the 23 June referendum vote to leave the European Union.

"These manifestations of hate and intolerance have a negative impact on the whole of British society, undermining the security of minority and immigrant communities. The current political climate in the United Kingdom provides absolutely no justification for racism and xenophobia," said Director Link.

He also commended the strong national response by Prime Minister David Cameron and other national leaders. "By publicly denouncing these incidents, the authorities have sent a strong message that bias motivated attacks have no place in the United Kingdom. I add my voice to those calling for the swift identification and prosecution of the perpetrators."

The National Police Chiefs’ Council reported a 57 per cent increase in reporting to True Vision, the online hate crime reporting site run by the police, between 24 and 27 June, compared to the same time in May 2016. ODIHR has also received reports of hate crimes and expressions of concern about the safety of people living in the United Kingdom.

JUI-F plans protests against Gaza genocide

MANSEHRA: Jamiat Ulema-i-Islam-Fazl provincial emir Maulana Attaur Rehman on Wednesday said that his party was going to launch a protest movement against Israel’s genocide in Gaza.

“I am here to invite you to our Dec 8 conference in Peshawar to demand an end to the killing of Palestinian men, women, and children by Israeli forces in Gaza,” Mr Rehman told a gathering here.

JUI-F district emir and former senator Hidayatullah Shah and provincial acting general secretary Maulana Nasir Mehmood also addressed the gathering.

Mr Rehman said JUI-F central emir Maulana Fazlur Rehman would address the Peshawar conference.

“We expect over one million people will attend the moot from across the country, especially Khyber Pakhtunkhwa, to show solidarity with Palestinians against Israeli brutalities,” he said.

Moot to be held in Peshawar to show solidarity with Palestinians

The JUI leader said his party was striving for the enforcement of Shariah in the country through peaceful and political means, hoping that the struggle would eventually succeed.

He said the party chief, Maulana Fazlur Rehman, helped steer the country out of constitutional and political crises and played a pivotal role in the enactment of 26th Constitutional Amendment, which carried a clause for the elimination of usury from the country.

Mr Rehman acknowledged rifts in the party’s Mansehra chapter and promised corrective measures.

DRIVE AGAINST ENCROACHMENT: The tehsil municipal administration on Wednesday launched a campaign against encroachments in Mansehra city and its suburbs.

“We have removed temporary and permanent illegal structures to ensure the smooth flow of traffic,” tehsil municipal officer Mazhar Muzzaffar Awan told reporters.

A joint team from the police and TMA cleared encroachments from along Abbottabad Road, Kashmir Road, and Shinkiari Road.

It also took away handcarts and goods placed outside shops and markets, and warned traders of strict legal action in case of road and pavement encroachments in the future.

“This anti-encroachment drive will be extended to the areas where traders have already been given notices to voluntarily remove structures obstructing traffic,” he said.

Mr Awan said handcarts and fruit and vegetable stalls outside the King Abdullah Teaching Hospital were also removed.

“We are also taking strict action against TMA’s officials who either remained absent or failed to attend to their duties regularly and a biometric system has been installed that verifies staff attendance using facial recognition,” he said.

The TMO said that officials still absent from duty were served with show-cause notices.

“We will terminate employees who remain absent and fail to respond to the notices,” he said.

The official said dumping sites were being relocated to protect people’s health and life.

“With the rainy season underway in the district, we have cleared all choked drains and sewage lines along the Karakoram Highway,” he said.
