Thousands of elevator permits in San Diego County are out of date, according to the Department of Industrial Relations. In San Diego and Imperial Counties, a DIR spokesperson said there are 12,541 elevator permits issued. Of those, 6,932 are expired. DIR spokesperson Frank Polizzi said there is no penalty for expired permits, “but a unit should not be running if it has been tagged out of service for a maintenance/safety reason.”Team 10 visited several elevators in downtown San Diego and found there was no permit displayed in the elevator at all—including an elevator at Horton Plaza and one operated by the City of San Diego. Polizzi said there are other reasons a displayed permit could be expired, besides the elevator being out of compliance. The owner could be waiting for a Cal/OSHA permit inspection or they have not posted the most updated permit. 868

TIJUANA, Mexico (AP) — Migrants in a caravan of Central Americans scrambled Wednesday to reach the U.S. border, arriving by the hundreds in Tijuana, while U.S. authorities across the border were readying razor wire security barriers.Mexican officials in Tijuana were struggling to deal with a group of 357 migrants who arrived aboard nine buses Tuesday and another group of 398 that arrived Wednesday."Mexico has been excellent; we have no complaint about Mexico. The United States remains to be seen," said Josue Vargas, a migrant from Honduras who finally pulled into Tijuana Wednesday after more than a month on the road.U.S. Defense Secretary Jim Mattis, meanwhile, went to visit U.S. troops posted to the border in south Texas and said the deployment provides good training for war. President Donald Trump has said the caravan of migrants amounts to an "invasion."RELATED: Video shows people climbing on top of fence at Border Field State ParkThat didn't deter arriving groups of Central Americans from going to a stretch of border fence in Tijuana to celebrate.On Tuesday, a couple of dozen migrants scaled the steel border fence to celebrate their arrival, chanting "Yes, we could!" and one man dropped over to the U.S. side briefly as border agents watched from a distance. He ran quickly back to the fence.Tijuana's head of migrant services, Cesar Palencia Chavez, said authorities offered to take the migrants to shelters immediately, but they initially refused."They wanted to stay together in a single shelter," Palencia Chavez said, "but at this time that's not possible" because shelters are designed for smaller groups and generally offer separate facilities for men, women and families.But he said that after their visit to the border, most were taken to shelters in groups of 30 or 40.With a total of three caravans moving through Mexico including 7,000 to 10,000 migrants in all, questions arose as to how Tijuana would deal with such a huge influx, especially given U.S. moves to tighten border security and make it harder to claim asylum.On Wednesday, buses and trucks carried some migrants into the state of Sinaloa along the Gulf of California and further northward into the border state of Sonora.The bulk of the main caravan appeared to be about 1,100 miles (1,800 kilometers) from the border, but was moving hundreds of miles per day.The Rev. Miguel Angel Soto, director of the Casa de Migrante — House of the Migrant — in the Sinaloa capital of Culiacan, said about 2,000 migrants had arrived in that area. He said the state government, the Roman Catholic Church and city officials in Escuinapa, Sinaloa, were helping the migrants.The priest also said the church had been able to get "good people" to provide buses for moving migrants northward. He said so far 24 buses had left Escuinapa on an eight-drive to Navojoa in Sonora state. Small groups were reported in the northern cities of Saltillo and Monterrey, in the region near Texas.From Sonora, some migrants said they had already caught buses from to Tijuana.About 1,300 migrants in a second caravan were resting at a stadium in Mexico City, where the first group had stayed last week. By early Wednesday, another 1,100 migrants from the third and last caravan had also arrived at the stadium.Like most of those in the third caravan, migrant Javier Pineda is from El Salvador, and hopes to reach the United States. Referring to the first caravan nearing the end of the journey, Pineda said "if they could do it, there is no reason why we can't."It is unclear whether the two caravans would merge or when they would set out on the road north.Many say they are fleeing poverty, gang violence and political instability in the Central American countries of Honduras, Guatemala, El Salvador and Nicaragua.Mexico has offered refuge, asylum or work visas, and its government said Monday that 2,697 temporary visas had been issued to individuals and families to cover them during the 45-day application process for more permanent status. Some 533 migrants had requested a voluntary return to their countries, the government reported.The U.S. government said it was starting work Tuesday to "harden" the border crossing from Tijuana ahead of the caravans.Customs and Border Protection announced it was closing four lanes at the busy San Ysidro and Otay Mesa ports of entry in San Diego, California, so it could install infrastructure.That still leaves a substantial path for the tens of thousands of people who cross daily: Twenty-three lanes remain open at San Ysidro and 12 at Otay Mesa.San Ysidro is the border's busiest crossing, with about 110,000 people entering the U.S. every day. That traffic includes some 40,000 vehicles, 34,000 pedestrians and 150 to 200 buses.___Maria Verza contributed from Escuinapa, Mexico. 4804

There are plenty of services available to get food delivered to your door. But Uber plans to take delivery to a new level by using drones.The company reportedly plans to launch a food delivery service using drones by 2021.   How soon could this happen? Futurist Thomas Frey says it’s coming whether we want it or not.   "With all the emerging technology, we still have to work our way through the crappy stages before we get to the good stuff," says Frey.   Delivering food to anyone anywhere is a challenge  "Delivering something like food is a lot messier and a lot more time sensitive than delivering a product we're getting from Walmart or Amazon or something, says Frey."Part of the problem with drones is that we have to get the FAA to OK deliveries like this, and that is not a simple thing to do."   And with the convenience, comes a price.  "Eliminate a lot of human labor in doing something like this, so the reasons companies are pushing this so hard is it gives them a competitive advantage,” explains Frey. “It takes much of the labor costs out of this arrangement."  Overall, the good side of technology usually outweighs the bad, Frey says."See, drones can be very dangerous. The same ones that deliver foods or products to your door step they can also deliver bombs or poison or spy on your kids,” Frey says. “We have to guard against abuses of this technology."  Before this can happen, companies will be need to get a license and go through security training in order to get clearance.   1578

Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464
