NYC to limit shelter stay for asylum-seekers with children_我的网站

A |      8 月 24 日消息，据外媒 Phys.org 今天（24 日）报道，卡迪夫大学和墨尔本大学的一项新研究发现，生成式人工智能（GenAI）目前还无法像人类教师一样可靠地评判学生的书面作业。    New York City officials are limiting the time asylum-seekers with children can spend in the city's shelter system.Starting next week, city officials will begin notifying some families that they have 60 days to find alternative housing. Last month, NYC Mayor Eric Adams' administration announced it would be handing out 30-day notices for adult migrants without children.The move to restrict the amount of time in the shelter system comes as the city continues to grapple with a large number of asylum-seekers coming to the city since spring of last year. Over 126,000 asylum-seekers have moved through the shelter system so far since Spring 2022."For over a year, New York City has led the response to this national crisis, but significant additional resources, coordination, and support are needed from all levels of government. With over 64,100 asylum seekers still in the city's care, and thousands more migrants arriving every week, expanding this policy to all asylum-seekers in our care is the only way to help migrants take the next steps on their journeys," Mayor Adams said in a statement Monday.The mayor's office said it would pair the notices with "intensified case work" to help asylum-seekers figure out their next steps. A spokesperson for the mayor's office told ABC News that if someone fails to secure housing by the deadline, they'll need to return to the city's intake center and seek a new placement.Some advocates believe issuing the notices is a way for the Adams administration to limit its obligation's under the city's "right-to-shelter" laws which require the city to provide shelter for anyone in need. The city has asked a court to consider allowing the city to consider allowing it relinquish some of those obligations if it doesn't have "the resources and capacity to establish and maintain sufficient shelter sites, staffing, and security to provide safe and appropriate shelter," according to court filings.On Monday, the administration announced it will open a temporary shelter at Floyd Bennett Field in the coming weeks that will be serve approximately 500 families in a "semi-congregate setting" with privacy dividers and locks."It's outrageous the way the Adams administration continues to go out of its way to gut New York City's right-to-shelter protections. This policy ensures that all New Yorkers, no matter when they arrived here, can maintain a roof over their heads while they stabilize their lives and get on the road to self-sufficiency," Murad Awawdeh, the executive director of the New York Immigration Coalition, said in part in a statement.He added, "Now, Mayor Adams is putting children in danger by forcing some asylum seeking families to stay in congregate settings as well as mandating families re-apply for shelter after 60 days, a move that creates unnecessary bureaucratic hurdles for people who are already struggling."The spokesperson for the mayor's office told ABC News they hoped the city could continue housing migrants without forcing families with children on to the streets and reiterated the administration's call for more support from the state and federal governments.。

B | 研究人员使用 ChatGPT 的两个版本，对 50 篇生物科学专业本科生论文进行评分，以测试大模型评估学生作业的能力。ChatGPT 需要按照 7 项标准批改这些论文，研究人员还采用了 4 种不同的提示方式，随后将大模型与人工评分的平均分和分数波动情况进行比较。图源：Pexels卡迪夫大学生物科学学院威廉 · 凯博士指出：“研究结果显示，模型给出的分数波动很大，无法准确预测人工评分。

C | 生成式 AI 与人类批改同一批论文时存在明显差异。

D | 只看论文总分，两者给出的结果相对接近；一旦具体到每项评分标准和每一篇论文，大模型与人工评分之间的差距就相当明显。”除一种情况外，AI 模型给出的平均分普遍高于人工评分。

E | 平均分方面，AI 模型与人工评分的最大差距达到 16.1 分；具体到单篇论文，最大差距达到 40 分。获悉，威廉 · 凯还发现，AI 往往会压低高分论文的成绩，又把低分作业的成绩抬高，最终使分数系统性地向中间集中。研究结果说明，至少现阶段，即使经过大量训练，AI 仍无法可靠地对主观性较强的书面作业给出与人类相当的分数。“我们测试的大模型目前并不适合取代教师，为学生预测作业成绩。”研究人员指出，高等教育领域确实很关注大模型能否利用模式识别能力，让学生作业评分更加客观，同时提高批改效率、减轻教职人员压力。但这项研究表明，目前并不适合这么做。此外，未经学生明确同意便把作业提交给 AI 工具，本身还涉及伦理问题；大模型也不能、也不应该被依赖来给学生的长篇书面作业评分。“随着大模型继续发展，未来模仿人类判断的能力可能会提高。但从这项研究来看，要让 AI 给出的分数与人工评分真正保持一致，恐怕并不容易。
