A | Colombo, Oct 17 (UNI) The Sri Lankan government should withdraw a draft law that will give the authorities broad powers to detain people in military-run “rehabilitation” centers, placing them at great risk of abuse, Human Rights Watch (HRW) has said.
The HRW said the Bureau of Rehabilitation Bill, submitted to Parliament on September 23, would allow the compulsory detention in centers of “drug dependent persons, ex-combatants, members of violent extremist groups and any other group of persons”, the Daily Mirror reported on Monday.
“The Bureau of Rehabilitation Bill would establish a new administrative structure controlled by the Defense Ministry to operate 'rehabilitation' centers staffed by military personnel.
"The proposed law, which human rights advocates have already challenged in the Supreme Court, does not describe the basis for being sent for 'rehabilitation' but other recent government policies provide vague and arbitrary powers to forcibly 'rehabilitate' people who have not been convicted of any crime,” the HRW said.
“The Sri Lankan government’s proposed ‘rehabilitation’ efforts appear to be nothing more than a new form of abusive detention without charge,” said Meenakshi Ganguly, South Asia director at Human Rights Watch. “The Rehabilitation Bill would open the door widely to more torture, mistreatment, and endless detention.”
The Rehabilitation Bill is the latest measure in a long history of laws, such as the Prevention of Terrorism Act (PTA), that authorize arbitrary detention and torture in Sri Lanka. The law could be used to target minority communities or anti-government protesters.
UNI MR。北京时间1月14日消息,天文学家收到了许多来自遥远星系的神秘信号。当这些被称为快速射电爆发(FRB)的信号到达地球望远镜时,它们会显示持续数毫秒的明亮爆发,然后消失。在过去的十年里,天文学家已经检测到数十个快速的无线电脉冲信号,新的信号正在出现,其中包括一个罕见的重复信号。我们不清楚这些信号是什么,它们来自哪里。目前,科学家主要有以下五种猜测。当快旋中子星爆炸并死亡时,它们的最终结果可能是快旋中子星。天文学家相信,强磁场中的中子星可能会产生异常快的无线电波爆发信号。”加拿大不列颠哥伦比亚大学的天体物理学家IngridStairs说:“像中子星这样的物体确实是很好的信号源。”但是我们不知道这高能无线爆炸是通过什么物理过程产生的,两颗中子星合并两颗中子星相互碰撞是产生快速无线风暴的另一种可能性。

B | 加拿大麦吉尔大学的天文学家Shriharsh Tendulkar说,这是一个主流的假设,但只适用于只检测一次的宇宙信号,因为中子星在碰撞中被摧毁。_强磁场中的中子星(图像)可能会产生奇怪的快速无线电脉冲信号。”这是一个毁灭性的事件,不适合重复的快速无线电爆发,”尖利刺耳的tendulkar说。在过去的十年里,望远镜捕捉到的大多数快速的无线电风暴在一次出现后就消失了。然而,天文学家发现了两个反复出现的神秘信号,需要用其他理论来解释。当一颗快速旋转的中子星坍缩并形成一个黑洞时,闪电被称为“闪电”。

C | 快速的无线电风暴可能起源于闪电,但就像中子星合并一样,它们也是恒星毁灭的过程,因此不可能产生重复的信号。黑洞可能是快速无线电风暴的起源。许多假设都提到了黑洞。

D | 人们认为,快速的无线风暴可能来自中子星掉入黑洞,或来自黑洞坍塌,甚至来自暗物质与黑洞的碰撞。虽然许多天文学家认为快速的无线电风暴是完全自然的产物,但一些人推测它们可能是外星生命活动的证据。根据Steels博士的说法,射电望远镜能够探测到来自宇宙的快速射电风暴的可能性非常小。”它们的出现遍布整个天空,在不同的距离,所以它一定与许多不同的星系有关,”她说。如果许多不同的外星文明决定以同样的方式发送同样的信号,那将是令人惊讶的。似乎不太可能。
