Nonprofit seeks insight from devices left behind by veterans who died by suicide_我的网站

一 | The cell phones, tablets, and laptops left behind by veterans who died by suicide may offer insight that could help prevent future military suicides, according to a nonprofit dedicated to analyzing the data from the devices.Stop Soldier Suicide collects the technology as part of its initiative, "The Black Box Project," which is named after the black boxes found on planes that help determine the cause of aviation incidents."If we could gather novel data from those that have died by suicide, we might be able to recreate the last year of life," Stop Soldier Suicide CEO Chris Ford told ABC News.Veterans are 57% more at risk for suicide than non-military adults and around 6,000 veterans die by suicide each year, according to the Department of Veterans Affairs."I think we can prevent needless suffering and a ton of loss of life," Ford said.That kind of loss is something David McDaniel, whose son Connor died by suicide at the age of 26, knows all too well.Connor McDaniel joined the Army after high school, and, according to David, he appeared upbeat during his deployment to Afghanistan, where he was assigned to protect local villages from the Taliban."Some of his Army buddies told me that he was making them laugh while they were being shelled in Afghanistan," David McDaniel told ABC News.But it wasn't long after Connor came home that David McDaniel says he sensed a shift in his son's behavior to include "more anger, a lot of frustration, a lot of gloominess."On Sept. 1, 2021, David says his son entered a wooded area with a firearm."I start screaming his name as I'm walking up the field. And just then the police, the sheriff's department shows up and they tell me to come back down," McDaniel said.He followed their direction, but on the car ride home, an officer called him and said Connor was dead after he fired upon sheriff's deputies and the deputies returned fire and killed him.Connor's death was determined to be a suicide. The district attorney's office concluded that the officers' actions were justified.While grappling with his son's death, David McDaniel was immediately drawn to the Black Box Project, which uses forensic software to unlock and comb through service members' devices provided by their loved ones to review their activity in the weeks leading up to their suicides.McDaniel works in the tech field and says if the project can find repeated patterns in online searches, they may be able to help others to prevent suicides.For instance, McDaniel says his son searched for SGLI, Servicemembers' Group Life Insurance, before his death. If a veteran were to make a similar search and look up "suicide" in the future, for example, McDaniel suggests it could trigger an ad for Stop Soldier Suicide to pop up and provide resources in the search results.Ford says the nonprofit uses machine learning, a subfield of artificial intelligence, to analyze texts and notes in order to determine sentiment or emotional tone, such as anger or desperation. He says they can also track phone usage of the deceased veterans to monitor their past sleep cycles and trace their past geo-locations."Machines can go through computations a lot faster than humans, and they can find signals that we often miss," Ford said.Since launching the Black Box Project in April 2020, Stop Soldier Suicide has received over 100 devices, Ford said. So far, he says they're seeing three patterns before most of these suicides: more anger, different sleep patterns, and social isolation.Ford's team includes Ph.D.s in clinical psychology and suicide researchers. A scientific advisory committee helps steer where and what to look for on the devices.The findings are still preliminary, according to the nonprofit, but one goal is to help the organization decide where, when, and how to target their own mental health resources, like adding more hotline staff at certain hours and ensuring calls are picked up overnight.When asked about privacy concerns of collecting data, Ford said it's something they think about daily."We don't resell the data. We don't push it out to others. We use it for our own research purposes so that we can best understand risk and then give those devices back to those families intact," Ford said.Current privacy laws do not carry on past death, meaning the next of kin typically gains new authority.Petra Oxford-Jackson, whose veteran husband Anthony died by suicide, says she gave his phone to the organization with the possibility it could save even one life."I truly believe he would have been okay with it, and it's a hard thing for a survivor to give up something so personal as his cell phone," Oxford-Jackson told ABC News.The Black Box Project received $3 million in funding from the Department of Veterans Affairs earlier this year.If you are struggling with thoughts of suicide or worried about a friend or loved one, call or text the Suicide & Crisis Lifeline at 988 for free, confidential emotional support 24 hours a day, seven days a week.。 8 月 26 日消息，SpaceX 当地时间周二公布了在路易斯安那州建设一座大型太空港的计划，项目投资规模高达 1,000 亿美元（注：现汇率约合 6,738.71 亿元人民币）。该公司计划未来每年从这里发射数千次庞大的“星舰”（Starship）火箭。据当地经济发展网站介绍，这座太空港预计将于明年底前在路易斯安那州南部沿海的维尔米利恩教区附近动工，最早可能于 2029 年执行首次发射任务。

二 | 如果这一计划最终落地，将彻底改变 SpaceX 以及美国火箭产业的格局。路易斯安那州此前从未进行过轨道级火箭发射，而未来这里可能成为全球最繁忙的火箭发射基地。SpaceX 将把这座新园区命名为“路易斯安那星基地”（Starbase Louisiana），名称借鉴了该公司最近在得克萨斯州南部正式设立的“星基地”城镇。

三 | 目前，得州星基地是“星舰”的测试和研发中心，也是“星舰”进行飞行测试的主要地点。截至目前，“星舰”已经从那里完成了 13 次试飞，这些测试飞行取得了不同程度的成功。不过，路易斯安那州基地的定位有所不同。

四 | 这里主要负责“星舰”正式投入运营后的商业和任务发射，前提是“星舰”已经证明自己能够安全地将货物送入轨道。SpaceX 还计划让“星舰”的所有部件都能够着陆并回收，包括此前从未成功实现回收的上面级飞船，从而实现火箭快速重复使用，并进一步降低每次发射的成本。这意味着路易斯安那州未来不仅会成为火箭发射中心，还将建设大量高达数百英尺的发射塔，用于在火箭和飞船从太空返回时对其进行捕获。SpaceX CEO 埃隆 · 马斯克周二在社交平台 X 上表示：“路易斯安那星基地最终将拥有超过 12 座发射塔，每天能够执行超过 30 次‘星舰’发射，使其成为地球上最大的发射基地！”SpaceX 首席运营官格温妮 · 肖特韦尔周二在路易斯安那州举行的项目发布会上也表示，该项目将建设一座“自给自足的太空港”，拥有自己的推进剂生产设施、发电设施、深水航运能力、飞行器处理设施，甚至“可能还会有一座机场”。

五 | 事实上，SpaceX 已经与路易斯安那州政府官员秘密推进这一太空港计划数月之久。公司高管曾多次前往该州考察潜在选址，当地一家新闻媒体甚至将这一项目称为该州“最公开的秘密”。路易斯安那州州长、共和党人杰夫 · 兰德里则将该项目描述为一份能够带来“永久未来和持久繁荣”的承诺。

六 | 兰德里说：“几代人以来，各种产业来到路易斯安那州，并不是为了创造持久的繁荣，而是为了攫取财富。太多时候，路易斯安那州留下的是伤痕，而其他人享受了利润。

七 | 今天，埃隆 · 马斯克和他的团队为路易斯安那州提供的是另一条道路。”不过，目前仍有许多细节有待确认。“星舰”目前尚未正式投入运营。预计 SpaceX 最早将在今年 9 月进行迄今为止最重要的一次试飞任务，这次任务有望让“星舰”首次进入轨道。

八 | 与此同时，公司还需要进行更多测试，以解决“星舰”上面级如何着陆以及如何再次执行飞行任务等关键问题。如此规模庞大的路易斯安那州太空港，也很可能面临严格的监管审查。项目网站确认称：“该项目将接受所有适用的环境、湿地、自然资源以及与发射相关的审查。”SpaceX 在得克萨斯州的相关设施规模远小于计划中的路易斯安那州基地，但当地设施的相关审批和审查耗时接近 10 年。

九 | 目前，一些当地环保组织仍在得州法院与 SpaceX 交锋，争议焦点包括火箭测试对当地社区造成的影响。肖特韦尔周二表示，在路易斯安那星基地占地 12.5 万英亩的土地中，SpaceX 计划让“很大一部分”土地保持原貌，“确保高价值湿地继续作为栖息地，而不是变成基础设施”。她说：“在建设基地的同时，我们也会为保护、修复和管理这些区域提供资金支持。”此次宣布的计划，是 SpaceX 近期一系列展现其对“星舰”信心的举措之一。SpaceX 此前已经表示，公司开始逐步减少对主力“猎鹰 9”（Falcon 9）火箭的使用。猎鹰 9 目前仍是全球发射次数最多的运载火箭，而一旦“星舰”正式投入运营，SpaceX 计划让大多数任务转由“星舰”执行。就在周二早些时候，SpaceX 负责发射业务的副总裁基科 · 唐切夫表示，当天早晨发射的一枚猎鹰 9 火箭，将成为最后一枚从佛罗里达州发射 SpaceX 星链（Starlink）卫星的猎鹰 9。目前，佛罗里达州奥兰多以东地区拥有肯尼迪航天中心和卡纳维拉尔角太空军基地，这里也是全球最繁忙的航天发射区域。唐切夫说：“从现在开始，所有从佛罗里达州发射的星链任务都将使用‘星舰’。
