上海玫瑰美容医院祛眼袋手术价格上海招风耳手术价格Science and technology科学技术The joys of parenthood身为人父的喜悦Fathers day父亲节Having children really does make a man more content with life有了自己的孩子的确会让男人更热爱自己的生活WILL fatherhood make me happy?当爸爸会让我开心么?That is a question many men have found themselves asking, and the scientific evidence is equivocal.这是一个许多男人都会问自己的问题,然而科学家们对此的措辞却含糊不清。A lot of studies have linked parenthood—particularly fatherhood.许多研究项目将双亲的身份—尤其是父亲,with lower levels of marital satisfaction and higher rates of depression than are found among non-parents.和低满足感与高压抑感联系起来,而且认为那些没有为人父母的人们则要逍遥许多。Biologically speaking, that looks odd.从生物学的角度来说,以上的观点其实很滑稽。Natural selection might be expected to favour the progeny of men who enjoy bringing them up.因为从自然选择的角度来说,大自然会更加青睐那些由开心的父亲抚养大的孩子。On the other hand, the countervailing pressure to have other children, by other women, may leave the man who is aly encumbered by a set of offspring dissatisfied.从另一个角度来看,男人天性受到一种相反的压力,希望和其他女性生育更多的孩子,这种压力可能会让受到现有子女负累的父亲感到不满。To investigate the matter further Sonja Lyubomirsky, a psychologist at the University of California, Riverside, decided both to study the existing literature, and to conduct some experiments of her own.一位来自加州大学的心理学家,索尼娅·柳米尔斯基,为了弄清这件事情,决定在研究现存文献的同时,也亲自组织一些实验。The results, just published in Psychological Science, suggest parenthood in general, and fatherhood in particular, really are blessings, even though the parent in question might sometimes feel they are in disguise.她研究的结果,《心理科学》上刚发表了不久。研究结果显示,总体上来说,为人父母,的确是会受到祝福的,即便那些受访的父母很多时候觉得可能自己在接受调查时伪装了些东西。Dr Lyubomirskys first port of call was the World Values Survey.首先,柳米尔斯基士从世界价值观大调查开始着手。This is a project which gathers huge amounts of data about the lives of people all around the planet.这是个浩大的工程,用来收集海量的居住在这个星球各个角落里的人的数据。For the purposes of her research, Dr Lyubomirsky looked at the answers 6,906 Americans had given, in four different years, to four particular questions.柳米尔斯基士从这些数据中调出了6,906份来自美国的数据,用以进行她的研究。这些数据从四个不同的年份里收集获得,涉及了四个方面不同的问题。These were: how many children the responder had;这四个方面是:受访者有多少子女;how satisfied he was with life;他对自己的生活有多大程度的满足感;how happy he was;他的快乐感多大;and how often he thought about the meaning and purpose of life.以及他多少次思考过生活的意义和目标。She found that, regardless of the year the survey was conducted, parents had higher happiness, satisfaction and meaning-of-life scores than non-parents.结果她发现,剔除调查的年份因素之后,为人父母的人群比非父母人群具有更高的快乐感和满足感,生活意义项的得分值也更高。The differences were not huge,这些数据的差别其实并不明显,but they were statistically significant.但是从统计学的角度来看,其意义却非常重大。Moreover, a closer look showed that the differences in happiness and satisfaction were the result of mens scores alone going up with parenthood.另外,仔细查看这些数据会发现,男子在当了父亲后,快乐感和满足感会出现细小的差别,分数会越来越高。Those of women did not change.但是女性则没有变化。Armed with this result, Dr Lyubomirsky conducted her own experiment.有了这个结果做撑,柳米尔斯基士开始着手弄自己的实验了。The problem with projects like the World Values Survey is that, 不过诸如世界价值观大调查此类的大工程的问题是,because participants are asked to recall their feelings rather than stating what they are experiencing in the here and now, this might lead them into thinking more fondly in hindsight about their parenting duties than they actually felt at the time.它在收集数据时,要求参与者是回忆自己的感受,而不是叙述他们当下的经历,所以这就容易导致他们去深情地,美化地思考他们为人父母的责任,而不是他们当时真实的感受。Dr Lyubomirsky therefore gave pagers to 329 North American volunteers aged between 18 and 94, having first recorded, among other things, their sex, age, ethnicity, socioeconomic status, marital status and number of children.为此,柳米尔斯基士给329名来自北美地区的志愿者发了调查问卷。这些志愿者从18岁到94岁不等。她第一手记录下他们的性别,年龄,种族,社会经济地位,婚姻状态以及子女的数量。She told them they would be paged at random, five times a day.她告诉他们受访者将会被随机排列,一天五次受访。When they were so paged, they were asked to complete a brief response sheet about how they felt, then and there.当受访者被随机排列好后,将会被要求完成一份简明的答卷,用来调查关于其当时的感受。She did not, however, tell them why she was asking these questions.当然,柳米尔斯基士并没有告诉受访者她为何问他们这些问题。The upshot was the same as her findings from the World Values Survey.结果,这次的结局和她在世界价值观大调查项目里得出的结论是一致的。Parents claimed more positive emotions and more meaning in their lives than non-parents, and a closer look revealed that it was fathers who most enjoyed these benefits.相比那些还没做父母的人,为人父母者在他们的人生中显示出了更加积极的情感和更多对他们人生意义的积极思考。Moreover, further analysis revealed that this enhanced enjoyment came from activities which involved children rather than those that did not.同时,通过更加仔细的观察,显示出父亲在上述方面更加典型。另外,更进一步的分析表明了上述的那种积极和欢乐来自于有关孩子的活动。生活中不涉及孩子的日常活动则没有这种效果。It looks, then, as if evolution has bolted into men a psychological mechanism to keep them in the family.所以说,由此可见,似乎自然进化让男人们产生了一种心理学机制,把他们闩在了家庭里。At first sight, it is strange that women do not share this mechanism, but perhaps they do not need to.乍一看,似乎女性没有这种机制很奇怪,但是仔细想想,她们也许根本就不需要这种机制。They know, after all, that the children are theirs, whereas the best a man can do is hope that is true.她们至少知道,自己的孩子一定是自己生的。That, and a mans potential to father an indefinite number of offspring if he can find willing volunteers, might encourage him to stray from the bosom of his family.但是孩子是不是男人自己的血脉,他们只能祈求上天了。所以说,一个男人想做一大堆子子孙孙的父亲的潜在本能,会激励他挣扎着走出家庭的怀抱。Enjoying fatherhood, by contrast, will help keep him in the porch.但是,相反的,身为人父的喜悦,则会让他们在家里的门廊前停住脚步。 /201307/247868上海市第一人民医院宝山分院修眉多少钱 上海隆鼻手术大概多少钱

上海脂肪丰胸多少钱Corporate spending企业出If they build it如果他们建造了它Capital expenditure around the world has been disappointing世界各地的资本出一直令人失望WHEN companies spend money on new plant and equipment, jobs and economic growth are the result. One of the aims of central banks efforts to suppress interest rates is to encourage more such spending. But the latest survey from Standard amp; Poors, a rating agency, indicates that a boom is yet to materialise: in real terms, capital expenditure fell 1% in 2013, and is expected to decline again this year.当公司把钱花在新工厂和新设备上时,就业和经济就会上涨。中央努力压低利率,其中一个目的就是鼓励更多这样的出。但是从标准普尔,一家评级机构,最近的调查显示,这种繁荣还未成为现实:实际上,在2013年资本出下降1%,预计今年还将再次下降。Perhaps surprisingly, capex is falling in emerging markets, generally seen as the engine of the global economy. The emerging markets share of global capex fell from 34% in 2011 to 27% last year.新兴市场中的资本出通常本看作是全球经济的引擎,也许令人惊讶的是,这种资本出正在下降。新兴市场的资本出占全球资本出的比例从2011年的34%下降到去年的27%。The big investors have traditionally been mining and energy firms, accounting for 42% of global capex in 2013. But spending in both industries has slowed sharply and is expected to fall this year. Companies may be losing the leeway to spend: capex has been higher than free cashflow in three of the last five years. In addition, the investment boom of the past decade may mean that the supply of minerals has caught up with demand.大型投资者通常是矿产和能源公司,2013年这类公司的资本出占全球资本出的42%。但在这两个行业的的出却大幅放缓,且预计今年还会下降。公司也许会失去花钱的余地:在过去的5年中,已经有3年的资本出比自由现金流高 。此外,过去10年间的投资热潮也许意味着矿产的供给已经赶上需求。Spending on research and development has been more robust than capex, rising 4.7% in real terms in both 2011 and 2012. But momentum appears to be slowing, despite an improving economy: Ramp;D grew just 2.6% last year.研发出比资本出更加强健,在2011年和2012年都实际增长4.7%。尽管经济形势有所好转,但这一势头似乎正在放缓:去年研发出仅增长2.6%。Why havent companies taken advantage of cheap finance and spent more? An obvious reason is that corporate revenue has not been growing very fast. Given that constraint, capex does not look so meagre. For global non-financial companies, the ratio of capex to revenues is close to its highest level in a decade. But that also means companies are unlikely to boost spending by much more. A survey of British firms suggests that uncertainty about demand and the risk of weak returns are the main deterrents for executives deciding whether to increase capex.为什么没有公司利用廉价融资而增加出?一个显而易见的原因就是企业的收入没有迅速增长。考虑到这一约束,资本出看起来并没有那么贫弱。对于全球非金融企业,资本出与收入的比率接近10年来的最高水平。但这也意味着公司不太可能更多的刺激消费。对英国公司的调查表明,需求的不确定性和薄弱的风险回报是影响高管决定是否增加资本出的主要妨碍。It seems like a chicken-and-egg problem. Without a strong global recovery, companies will not spend more. But if they do not spend more, there will not be a strong recovery.这似乎是一个“鸡生蛋,还是蛋生鸡”的问题。没有强劲的全球经济复苏,企业将不会增加出。但是如果他们不增加出,就不会产生强劲的全球经济复苏。 /201407/310230上海人民医院激光去痣多少钱 闵行区韩式安全隆胸手术价格

上海市徐汇区宛平地段医院做双眼皮开眼角手术价格 Science and technology科学技术Metal fatigue in old aircraft老旧飞机的金属疲劳Flying rivets飞行侦查兵A new technique that listens for cracks in ageing aircraft一项侦听老化飞机断裂的新技术WHEN they were built, no one thought they would fly for so long.建造飞机的时候,没人认为它们会飞行这么久。But fitted with new engines and avionics, aircraft can be kept going for a very long time.但是装有新式引擎和航空电子设备的飞机能持续飞行很长一段时间。The average age of the worlds airliners is more than ten years, with some passenger jets 25 years old or more.全世界飞机的平均机龄超过10年,有些客机的机龄超过了25年。Military planes are more geriatric:军用飞机更是超龄:the Sikorsky Black Hawk helicopter entered service 31 years ago and the Lockheed C-5 Galaxy 40 years back.西科斯基公司的黑鹰直升机31年前开始役,洛克希德公司的C-5早用到40年了。Both are still going strong.这两款飞机还都强劲地飞行着。Some Boeing KC-135 aerial-refuelling planes, which are based on the venerable 707, have been flying for over 50 years.波音707原型机上发展起来的波音KC-135空中加油机有些已经飞行50多年了。Engineers reckon they could still be in the air when they are 80.工程师们测算80机龄时它们仍然能飞上蓝天。One thing that does ground old aircraft is the impending failure of their aluminium structure from metal fatigue.让老旧飞机搁浅的一件事就是飞机铝构造因为金属疲劳产生的故障隐患。This begins in parts that are subjected to repeated strains, such as where the wings join the fuselage.这种故障始于承受反复拉紧的部位,象机翼与机身的连接处。Constant flexing of the structure concentrates stress, which leads to microscopic cracks.这些构造部位的频繁伸缩使应力集中,导致微裂纹的产生。These cracks become more numerous and eventually large enough for the structure to fail.这些微裂纹越来越多,最后多到足以使这些部位的构造断裂。Aircraft engineers know a lot about how these cracks progress and keep an eye on them in routine overhauls.飞机工程师们对这些裂纹如何发展以及在例行检修中如何注意这些裂纹所知甚详。Nevertheless, they can be difficult and costly to find.不过发现这些裂纹可能很难且费用高昂。Apart from careful visual inspection, techniques like X-rays and ultrasonic probes are also used.除了仔细地目视检查外,也使用象X射线和超声探头这样的技术。Now a British company has come up with a low-cost way of monitoring cracks in aircraft, even while they are airborne.目前一家英国公司提出了一种成本低廉的监测飞机裂纹方法,即使飞机在飞行中。The trick that Ultra Electronics uses is to listen for them with a system called Asis.超级电子公司采用的诀窍是侦听带有自动语音识别系统的飞机。It does this by fitting small piezoelectric acoustic sensors to parts of the structure to detect the particular frequency of noise caused by a crack in aircraft-grade aluminium.把小型压电声传感器安装到这种构造部位上,检测由航空级铝材裂纹所致的特定频率的噪音,靠这样就能监测飞机裂纹。When first set up, Asis is calibrated to the acoustic signature of the aircraft.安装之初,Asis就按飞机的声波标记图进行了校准。The system can point engineers to where cracks are occurring because the sensors also record the precise moment it is “heard”.这个系统能向工程师指明哪里正在出现裂纹,因为传感器也记录裂纹噪音被“听到”的精确时刻。As the sound ripples through the structure it arrives at different sensors at different times, which can be used to work out the location and severity of the crack.因为声音呈波形在飞机构造中传播,它在不同的时间到达不同的传感器,这点能用来算出裂纹的位置和严重程度。Once on the ground, a touch-screen device a bit like an iPad is plugged into the system and shows where any cracks are on a three-dimensional image of the aircraft.一经在地面上把有点象iPad的触摸屏设备用插头插入系统中,它就会在飞机的三维图像上显示所有裂纹。Asis will be tried out later this year by Americas Defence Advanced Research Projects Agency.Asis将由美国国防高级研究计划局在今年晚些时候进行试验。A basic set-up to monitor the boom on a small helicopter starts at around ,000, says Rob McDonald, Ultra Electronics marketing director.超级电子公司的营销总监罗伯?麦克唐纳说,监测小型直升机嗡嗡声的基本设备起价大约6.5万美元。As to the future, he expects the company will explore how Asis might also monitor carbon-composite materials, which are being used increasingly in new aircraft.至于未来,他期待公司会探究怎么让Asis也能监测碳复合材料,碳复合材料在新式飞机中的应用渐增。Less is known about the long-term structural integrity of carbon fibre, but it is not prone to corrosion and is extremely tough, so with a bit of care and attention it might allow aircraft to fly even longer.虽然对碳纤维的长期结构完整性所知甚少,但是它不易腐蚀且极为坚硬,因此稍加关注它就可能让飞机飞行得更久。 /201306/242956静安区激光祛痘多少钱上海安全丰胸医院
