The structural and nonlinear optical properties of a new anilinium hybrid crystal of chemical formula (C6H7NCl+·NO3−)3 have been investigated. The crystal structure was determined from single-crystal X-ray diffraction measurements performed at a temperature of 100 K which show that the compound crystallizes in a noncentrosymmetric space group (Pna21). The structural analysis was coupled with Hirshfeld surface analysis to evaluate the contribution of the different intermolecular interactions to the formation of supramolecular assemblies in the solid state that exhibit nonlinear optical features. This analysis reveals that the studied compound is characterized by a three-dimensional network of hydrogen bonds and the main contributions are provided by the O...H, C...H, H...H and Cl...H interactions, which alone represent ∼85% of the total contributions to the Hirshfeld surfaces. It is noteworthy that the halogen...H contributions are quite comparable with those of the H...H contacts. The nonlinear optical properties were investigated by nonlinear diffuse femtosecond-pulse reflectometry and the obtained results were compared with those of the reference material LiNbO3. The hybrid crystals exhibit notable second (SHG) and third (THG) harmonic generation which confirms its polarity is generated by the different intermolecular interactions. These measurements also highlight that the THG signal of the new anilinium compound normalized to its SHG counterpart is more pronounced than for LiNbO3.

Senate President Pro Tem Kevin de Leon is introducing a new bill on Wednesday that aims to address the state's critical child care shortage and give providers the right to unionize.

The lack of sufficient child care has been statewide. In Los Angeles County, a recent study found only 2 percent of infants and toddlers have access to a licensed child care facility; for preschoolers, it's about 40 percent.

The shortage is most acute in low-income areas, and the bill aims to inject more child care vouchers into the system so poor families can have free child care.

A more controversial provision, however, would allow collective bargaining for those who provide child care in their homes whose earnings can fall near or below the minimum wage. Child advocates cite poor pay as a major reason why providers often leave the field.

“The turnover in the child care field is approaching 30 percent. So the lack of continuity and quality care is a major obstacle,” said El Cerrito Mayor Mark Friedman.

Friedman co-chairs a coalition of early childhood groups called Raising California Together. Preschool advocacy groups, anti-poverty and immigrant groups, NAACP, and the Santa Monica school district count among its members.

“I think one thing everybody agrees on as a high priority is getting more resources in the system, and if there is a strong union presence in the field that then there will be a stronger voice for those additional resources,” said Friedman. 

Under the bill,  a network of 32,000 home childcare providers statewide could unionize. Currently, providers operate as independent business owners and typically lack the right to organize and collectively bargain for wages.

Finding child care

For many families, having a quality child care option is their most pressing need.

Vicky Montoya, a Reseda mother of three, is desperate for a child care alternative to family members. Montoya’s 18-month-old son, Esteban, is a bright-eyed toddler who loves balls. He can fling one clear across a room, even a field. But all too often, when both his parents are at work, he’s not doing much.

“Sometimes he’s with an aunt, sometimes with my eldest daughter,” Montoya said in Spanish. “But he doesn’t really do anything, all he does is watch cartoons on TV. And he’s alone, there’s no other children around.”

Montoya works five hours a day at a solar company, where she makes $10 an hour. Her family depends on her income to supplement her husband’s low-wage, full-time job. Montoya applied for a child care voucher so Esteban could go to a properly licensed day care. She submitted two applications to a local agency over the last two months.

When she called the agency to find out the status of her applications, she said she wasn't given much information. “'You are on the waiting list,'” she said they told her, “'and there are people ahead of you.'”

Seeking unions as a solution

In Maryland, unionized providers reduced the wait list for poor families by 80 percent by securing state dollars to fund more free child care slots. According to a 2010 report by the National Women's Law Center, 14 states guarantee home-based child care workers the right to unionize.

SEIU Local 99 spokesperson Terry Carter said what local providers tell her is that they want a seat at the table where child care decisions are made.

“What collective bargaining would do for providers is it would let them sit down with the top decision makers in the state and say these are things that are simple to fix, they would vastly improve our ability to operate our businesses and they would give us the time to direct more of our attention and energies into raising California’s kids,” Carter said.  

Some of those issues include delayed government payments for subsidized child child and the low reimbursement rate from the state for serving low-income kids.

Antonia Rivas, a Reseda child care provider, knows well the struggle of providing care in her home. She infuses yoga and meditation into daily lessons, and buys organic food, her major expense.

But she also has to pay her assistants, buy toys, books, and supplies. After her costs, she said there is not much left.

“I just got my 2014 W-2 and it's $24,000,” Rivas said. Her W-2 comes from the agency that pays her for the low-income kids she serves. Add to that the $15,000 from her private paying families and Rivas pulled in about $40,000 last year. After expenses, she estimates she netted less than the minimum wage for her time.

Rivas said with her low wages and delays in receiving payments from government agencies for subsidized child care, she is constantly relying on credit to keep her business running.

“We need to get a contract [and] better pay,” Rivas said.

Even if the child care legislation passes, a contract with the state would be a long way down the road. All child care providers would need to vote on whether they want union representation. And, if all that is successful, child care providers could then negotiate a labor contract.

Similar bills granting child care providers the right to unionize have made it out of the legislature, but both Gov. Arnold Schwarzenegger and Gov. Jerry Brown have vetoed them.

Opponents have called the effort to organize providers a move to empower labor unions, not fix a broken child care system. 

Recent legal rulings are also presenting challenges to unions seeking to organize both child care workers and health care workers. The U.S. Supreme Court ruled last year in an Illinois case that home health workers could opt out of paying union dues, even though they are paid with state subsidies.

While Vicky Montoya waits for a better solution for her son's care, she pays Esteban’s aunt or a neighbor $10 a day to watch him while she works.

“I know lots of families who have to leave their children with a babysitter, usually just a woman who watches the child. But they are not trained and even their homes are not suitable for childcare,” she said.

Insufficient evidence exists to support claims that taking megadoses of dietary antioxidants, such as selenium and vitamins C and E, or carotenoids, including beta-carotene, can prevent chronic diseases, says the latest report on Dietary Reference Intakes (DRIs) from the Institute of Medicine of the National Academies.

The United States should ban human reproductive cloning aimed at creating a child.

To meet the bodys daily energy and nutritional needs while minimizing risk for chronic disease, adults should get 45 percent to 65 percent of their calories from carbohydrates, 20 percent to 35 percent from fat, and 10 percent to 35 percent from protein.

The vast majority of healthy people adequately meet their daily hydration needs by letting thirst be their guide, says the newest report on nutrient recommendations from the Institute of Medicine of the National Academies.

The National Academies today recommended guidelines for research involving human embryonic stem cells, and urged all institutions conducting such research to establish oversight committees to ensure that the new guidelines will be followed.

A preponderance of scientific evidence shows that even low doses of ionizing radiation, such as gamma rays and X-rays, are likely to pose some risk of adverse health effects, says a new report from the National Academies National Research Council.

Long-term population trends for some North American pollinators -- bees, birds, bats, and other animals and insects that spread pollen so plant fertilization can occur -- are demonstrably downward, says a new report from the National Research Council.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome -- commonly referred to as ME/CFS -- is a legitimate, serious, and complex systemic disease that frequently and dramatically limits the activities of affected individuals, says a new report from the Institute of Medicine.

Over the last 25 years, deep-water oil and gas production in the Gulf of Mexico has increased significantly.

The 2011 Fukushima Daiichi nuclear accident should serve as a wake-up call to nuclear plant operators and regulators on the critical importance of measuring, maintaining, and restoring cooling in spent fuel pools during severe accidents and terrorist attacks, says a new report from the National Academies of Sciences, Engineering, and Medicine.

To improve and ensure the efficacy of restoration efforts in the Gulf of Mexico following Deepwater Horizon – the largest oil spill in U.S. history – a new report from the National Academies of Sciences, Engineering, and Medicine recommends a set of best practices for monitoring and evaluating ecological restoration activities.

A new report from the National Academies of Sciences, Engineering, and Medicine outlines how to examine whether specific levels of nutrients or other food substances (NOFSs) can ameliorate the risk of chronic disease and recommends ways to develop dietary reference intakes (DRI) based on chronic disease outcomes.

Monitoring the quality and impact of undergraduate science, technology, engineering, and mathematics (STEM) education will require the collection of new national data on changing student demographics, instructors’ use of evidence-based teaching approaches, student transfer patterns, and other dimensions of STEM education, says a new report from the National Academies of Sciences, Engineering, and Medicine.

If the dilute and dispose approach for disposing of the surplus plutonium in the Waste Isolation Pilot Plant (WIPP) is fully implemented, the U.S. Department of Energy (DOE) should use two independent review teams to develop public trust in and improve its decisions, says a new interim report by the National Academies of Sciences, Engineering, and Medicine.

Feb. 26 Symposium Will Explore How Scientific Research Should Evolve in Coming Decades

The U.S. Department of Energy’s plan to dilute and dispose of 34 metric tons of surplus plutonium in the Waste Isolation Pilot Plant (WIPP) in New Mexico is technically viable, provided that the plan’s implementation challenges and system vulnerabilities are resolved.

The L.A. Philharmonic will be the new operator of the John Anson Ford Theatre, the smaller outdoor venue near  the 101 Freeway across from the Hollywood Bowl, under a plan approved by the Los Angeles County Board of Supervisors.  

L.A.  funding sustains the Ford, and the county recently spent $80 million renovating the 1,200  seat amphitheater.  But attendance has been lackluster — and Supervisor Sheila Kuehl hopes the L.A. Philharmonic can change that. 

“The Ford will be able to take advantage of the natural synergies in marketing, capacity-building and program resources that simply haven’t been available to the Ford as an independent institution," she  said.

The move by the L.A. County  blindsided many local artists.  They say the Ford is an important incubator for diverse talent.  They also worry ticket prices will increase.  Prompted by their criticism, the Supervisors will require the Phil to meet with artists and annually review the diversity of the Ford’s shows with county officials.

Rachel Mason had, to a certain extent, the normal upbringing you’d imagine a family of five with small business owner parents would have. But in her documentary, ‘Circus of Books’, she pulls the curtain on the double-life her parents led as modest business owners and pillars of the LGBTQ community.

Karen and Barry Mason established West Hollywood’s Circus of Books on Santa Monica Boulevard in the 1980s. What seemed like an unassuming bookstore was actually a gay porn shop that became an institution in the LGBTQ community during a time when homosexuality was still largely unaccepted. The store was far from being a “bookstore with a circus theme”. The Los Angeles-based shop was the central hub for gay pornography around the country, once one of the main distributors for adult films. 

While the store was becoming a home for gay culture and pride, the Masons largely kept their business a secret from colleagues, friends, family, even their own children. It’s a central conflict that Rachel Mason explores throughout the film as the daughter of two shop owners caught between the pressures of maintaining a traditional family image and making a living as gay pornography distributors.

Today on FilmWeek, we’re joined by ‘Circus of Books’ director Rachel Mason for a conversation on her documentary and the experience of creating a film with her parents and their secret as the subject.

‘Circus Of Books’ is currently streaming on Netflix. For more on the film from LAist’s Mike Roe, click here.

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

Organisations are increasingly applying green business principles. According to a recent study, electronics manufacturing companies in Taiwan that practice green supply chain management (GSCM) have a better business performance than companies that do not. Those with a strong green marketing focus performed the best, successfully competing with their rivals.

There is a need for greater harmonisation of the methods used to estimate the environmental impact of products, otherwise known as product category rules (PCRs). A new study has reviewed the development of PCRs and provided recommendations for better alignment.

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

According to new research, improved communications and financial assistance could encourage private forest owners to engage more willingly in forest management. Personal economics, moral obligations, traditional ideas of how a forest should look and fear of forest fires were found to influence whether forest owners participate in management activities.

Standardised methods of categorising environmental data are needed at European and international levels for effective international policies. A recent study has concluded that a European framework that harmonises environmental data at the continental scale corresponds well with national classification systems, although some modifications may be needed to capture small-scale regional variations.

A fossil that has been in the collection of the Smithsonian's National Museum of Natural History since it was discovered in 1951 is today helping scientists piece together the evolutionary history of whales and dolphins, including the origins of the endangered South Asian river dolphin.

Researchers from the University of Oxford's Bodleian Libraries and from universities in the Netherlands have used high-tech imaging to uncover the details of a rare Mexican codex dating from before the colonization of the Americas. The newly revealed codex, or book, has been hidden from view for almost 500 years, concealed beneath a layer of plaster and chalk on the back of a later manuscript known as the Codex Selden, which is housed at the Bodleian Libraries. Scientists have used hyperspectral imaging to reveal pictographic scenes from this remarkable document and have published their findings in the Journal of Archaeological Science: Reports.
