脱水模式给他打赏只看楼主阅读设置
Students who did about an hour of ;mindfulness training; for eight days subsequently did better on the GRE as well as tests of working memory and mind-wandering.假如一名学生在连续八天的时间里每天做半小时的“正念冥思”,他在参加GRE考试或者做短期和注意力分散的测试时表现会更好。Improving memory and ability to focus takes years of cultivation and training, but getting the most out of your abilities as they stand is another valuable skill.问题:互联网可能会损害我们的注意力周期和短期记忆,但公司仍要求员工“集中注意力”。同时,尽管标准化的考试成绩很少能预测一位学生将来事业上是否成功,但高校的招生部门仍乐此不彼。改善和集中注意力的能力需要经过多年的培养和训练,但尽最大可能把你已有的能力发挥出来也是一种有价值的技巧。METHODOLOGY: Researchers at University of California at Santa Barbara had 48 undergraduate students take either a mindfulness class or a nutrition class. Classes met for 45 minutes four times per week for two weeks. They were taught by ;professionals with extensive teaching experience in their respective fields.; The mindfulness class ;emphasized the physical posture and mental strategies of focused-attention meditation.; As they describe that class more specifically:方法:在圣芭芭拉的加州大学研究人员把48名大学生分成两组,一组参加正念培训班,另外一组参加营养学培训班。这两个培训班都是每节课45分钟,每周四节课,连续上两周的课。学生们由在各自领域有丰富教学经验的专业人员上课。正念培训班的重点“在于做集中注意力冥思时所采用的身体姿势和精神策略”。他们对这个班的学习内容做了具体的描述如下:It required participants to integrate mindfulness into their daily activities and to complete 10 minutes of daily meditation outside of class. During class, participants sat on cushions in a circle. Each class included 10 to 20 minutes of mindfulness exercises requiring focused attention to some aspect of sensory experience (e.g., sensations of breathing, tastes of a piece of fruit, or sounds of an audio recording). ... Classes focused on:要求参加者把冥思融入到日常生活的行为当中,每天在课外完成10分钟的冥思。上课时参加者围坐在坐垫上,每节课包括10-20分钟的冥思练习,要求把注意力集中到某种感官体验上(如呼吸的感觉、一块水果的味道,或播放录音的声音等)。上课的重点在于:Sitting in an upright posture with legs crossed and gaze lowered, distinguishing between naturally arising thoughts and elaborated thinking保持身体挺直双腿盘坐的坐姿,目光低垂,辨别出自然产生的想法和故意的思维。Minimizing the distracting quality of past and future concerns by reframing them as mental projections occurring in the present通过改变思维方式把过去和未来关心的事项变成当下的精神投射以减少它们带来的干扰。Using the breath as an anchor for attention during meditation在冥思时利用呼吸来做注意力的“锚地”(即把注意力集中到自己的呼吸上来)。Repeatedly counting up to 21 consecutive exhalations [Ed. note: presume inhalations occurred as well.]在数到21的时间里连续吐气,反复做(设想在这期间也有吸气发生)。Allowing the mind to rest naturally rather than trying to suppress the occurrence of thoughts.让头脑自然休息,不要试图去压制头脑里产生出来的思维。The students in both classes took the GRE (Graduate Record Examinations; the standardized tests considered for grad school application) before and after the two-weeks of class, as well as tests of memory and distractibility, where they counted their ;task-unrelated thoughts; while doing things that required concentration.两个班级的学生在上这两星期课的先后都参加了GRE考试,还进行了和注意力分散的测试,在测试中他们对需要集中注意力时产生的“与任务无关的思维”进行了计数。RESULTS: Scores improved in the mindfulness-trained group, but not the nutrition-trained group. For one, their average GRE verbal score went from 460 to, two weeks later, 520. They also improved on tests of working memory and focus (had fewer task-unrelated thoughts).结果:参加正念培训班的学生成绩有了提高,但参加营养学培训班的学生却没有改进。正念培训班学生的GRE成绩由两周前的460分提高到了520分,对短期和注意力集中进行测试的成绩也比以前有了提高(与任务无关思维的次数减少了)。IMPLICATIONS: Taking time to think about your thoughts, breathing, posture, and the like can be valuable to overall cognitive functioning. This is the opposite of staying in a library for 86 hours fueled by Adderrall and anxiety. Kaplan#39;s GRE prep course is , 299, and a ton of people buy it. Meditation is free, so while that much is invested, this is probably worth checking out. Even if you can#39;t find time to meditate exactly, there#39;s always a moment to think intensely about fruit or ;your breathing as an anchor.;意义:花一点时间来思考一下你的思维、呼吸、姿势以及诸如此类的事情对整体的认知功能会有好处,这样做与待在图书馆里86个小时靠吃安神丸来集中注意力正好相反。卡普兰的GRE准备课程要卖1299美元,有许多人购买了这个课程,而冥思却是免费的。既然这么大的代价也舍得花,我们不妨来试一试冥思的功效。即便你没有时间来做冥思,花上片刻时间来想一想水果的味道或者“把呼吸作为集中注意力的锚地”总是可以的。 /201305/242200If the Internet has one enduring constant, it#39;s that somewhere, somehow, somebody is being hacked. Last month cyberassaults on banks, including BBamp;T (BBT, Fortune 500), Citigroup(C, Fortune 500), and SunTrust (STI, Fortune 500), made headlines. But a recent Ponemon Institute survey reported that the average company is attacked twice a week and loses .9 million a year to cybercrime. Security analysts say the first thing businesses must know is just what types of threats are lurking in the shadows. While many hackers use relatively basic tools, such as phishing or malware, they often wield them with different motives. Here are six of the most effective actors.如果说互联网有一个永恒的主题的话,那就是总有某些人在某处被黑客以某种方式攻击了。上个月,针对发起的网络攻击再次成为头条新闻,受害者包括BBamp;T公司、花旗集团(Citigroup)和太阳信托(SunTrust)。不过最近由波尼蒙研究所(Ponemon Institute)所做的一项调研显示,各公司每周平均受到两次攻击,每年由于网络犯罪损失的金额高达890万美元。安全分析师称,企业首先要了解藏在暗处的到底是何种威胁。尽管许多黑客用的只是相对基础的工具,比如网络钓鱼或恶意软件,但他们运用这些工具的目的各有不同。下面我们为大家盘点了六类最有攻击力的黑客。1. State sponsored政府撑腰的黑客Who: Iran, Israel, Russia, U.S.身份:伊朗,以色列,俄罗斯,美国Objectives: Intelligence, state secrets, sabotage目的:情报,国家机密,破坏活动Targets: Foreign governments, terrorists, industry目标:外国政府,恐怖分子,各种产业Signature: Multi-tiered, precisely orchestrated attacks that breach computer systems特征:精心组织的破坏计算机系统的多层次攻击Classic Case: One-fifth of Iran#39;s nuclear centrifuges crashed after Stuxnet, a worm reportedly developed by U.S. and Israeli intelligence, penetrated computers at an Iranian enrichment facility. Iran allegedly retaliated by disrupting access to the websites of J.P.Morgan (JPM, Fortune 500), PNC (PNC, Fortune 500), Wells Fargo (WFC, Fortune 500), and others.经典案例:受到震网病毒攻击后,伊朗核工厂五分之一的离心机崩溃了。它是一种蠕虫病毒,据称由美国和以色列情报机构开发,能侵入控制伊朗浓缩装置的电脑。而伊朗随后就发起了反击,使用户无法访问根大通(J.P.Morgan)、PNC,富国(Wells Fargo)及其他金融机构的网站。2. Hacktivist维权黑客Who: Anonymous, AntiSec, LulzSec身份:匿名组织,反安全组织,鲁兹安全Objectives: Righting perceived wrongs, publicity, protecting Internet freedoms目的:修正已知错误,推广自身,保护互联网自由Targets: Bullies, Scientologists, corporations, governments目标:网络坏分子,科学论派,公司,政府Signature: Leaking sensitive information, public shaming, creepy YouTube s特征:泄露敏感信息,公开羞辱,潜入YouTube视频Classic Case: The websites of PayPal, Visa (V, Fortune 500), and MasterCard (MA,Fortune 500) were disrupted during Operation Payback, an Anonymous-led effort to punish companies that suspended the accounts of WikiLeaks in 2010. Some .6 million was lost by PayPal alone.经典案例:在所谓的“报复行动”(Operation Payback)中,贝宝(PayPal)、维萨信用卡(Visa)和万事达信用卡(MasterCard)的网站都遭到了破坏。这是一次由匿名组织发起的行动,旨在惩罚那些2010年冻结维基解密(WikiLeaks)账户的公司。仅贝宝一家公司就因此损失了560万美元。3. Cyber-Criminal网络犯罪Who: Nigerian ;princes,; carders, identity thieves, spammers身份:尼日利亚“王子”,信用卡盗用者,身份窃贼,垃圾邮件制造者Objective: Treasure目的:劫财Targets: The gullible, online shoppers, small businesses, data-rich health care and retail companies目标:容易上当的人,在线购物者,小企业,拥有大量数据的保健机构和零售企业Signature: Stealing data, looting bank accounts特征:盗窃数据,洗劫账户Classic Case: Coreflood, malicious software that records keystrokes and passwords, infected 2.3 million computers in 2009, some in police departments, airports, banks, hospitals, and universities. Affected companies suffered six-figure fraudulent wire transfers.经典案例:2009年,专门记录击键动作和密码的恶意软件Coreflood感染了230万台电脑,其中包括一些警察局、机场、、医院和大学的电脑。受害公司遭到高达6位数的虚假电子转账侵袭。4. Insider (You)内鬼Who: Disgruntled employees, contractors, whistleblowers身份:心怀不满的员工,承包商,举报人Objectives: Score-settling, leaks, public good目的:利益之争,泄露信息,公共利益Targets: Large companies, governments目标:大公司,政府Signature: Document theft特征:窃取文件Classic Case: Maroochy Shire, an Australian district along the Sunshine Coast in Queensland, was inundated with millions of gallons of untreated sewage in 2001 when a contractor hacked and took control of 150 sewage pumping stations. He had been passed over for a job with the district. His dirty work cost Maroochy Shire upwards of million.经典案例:马谷志郡位于澳大利亚昆士兰州阳光海岸。2001年,一个承包商用黑客攻击并控制了当地150座污水泵站,导致该地区被上百万吨未处理的污水淹没。他这么干的起因是在该地区的一项业务承包中落选。结果,这次卑鄙行为让马谷志郡损失了超过100万美元。5. Script Kiddie脚本小子Who: Bored youth身份:无聊的年轻人Objectives: Thrills, notoriety目的:寻求刺激,得恶名Targets: Low-hanging fruit such as unprotected websites and e-mail accounts目标:容易下手的对象,比如没有保护措施的网站和电子邮件账户Signature: Defacing or dismantling websites特征:丑化或破坏网站Classic Case: An e-mail subject-lined I LOVE YOU duped people -- some of them inside the Pentagon -- in 2001. The virus it contained, which originated in the Philippines, destroyed files and simultaneously replicated itself, seeding in-boxes as it went. The so-called Love Bug caused an estimated billion in digital damage and lost productivity.经典案例:2001年,一封主题为“我爱你”的电子邮件把人们弄得晕头转向——包括一些五角大楼的人。这封信含有来自菲律宾的病毒,它在破坏文件的同时进行自我复制,在收件箱里扎根。所谓的“爱虫”所引起的数据破坏和生产力损失估计高达100亿美元。6. Vulnerability Broker漏洞经纪人Who: Endgame, Netragard, Vupen身份:Endgame公司,Netragard公司,Vupen公司Objective: Hacking as legitimate business目的:把黑客行为当成合法生意Targets: Agnostic目标:未可知Signature: Finding so-called zero-day exploits -- ways to hack new software, selling them to governments and other deep-pocketed clients特征:找到所谓的“零天攻击”代码(zero-day exploit)——即攻击新软件的方法,再把它们卖给政府和其他财大气粗的客户。Classic Case: French firm Vupen hacked Google#39;s (GOOG, Fortune 500) Chrome browser at a security conference last March. Rather than share its technique with the company (and accept a ,000 award), Vupen has been selling the exploit to higher-paying customers.经典案例:去年3月举行的一次安全会议上,法国公司Vupen黑掉了谷歌公司(Google)的Chrome浏览器。这家公司并没有(收下6万美元,)把这项技术和谷歌分享,而是把代码卖给了出价更高的客户。 /201303/228211
