Observations made over the past 29 years in Kenya as part of one of the world’s longest-running studies of a wild primate show how having offspring influences the health of female baboons. These observations highlight that females are mostly injured on days when they are likely，. In addition, injuries heal the slowest when they are suckling their young
The study, published in Springer’s journal Behavioral Ecology and Sociobiology, is led by Elizabeth Archie of the University of Notre Dame in the US and the National Museums of Kenya. Reproduction can be dangerous and energetically costly, exposing individuals to physical harm, infectious disease and reduced immunity.
To investigate how long-lived, slow-reproducing species such as primates adjust to this, Archie and her colleagues turned to data collected as part of the Amboseli Baboon Research Project near Kilimanjaro 中醫論汗.
Here, trained observers have made almost daily notes since 1971 on groups of yellow baboons. Among others, 707 injuries to 160 female baboons between 1982 and 2011 were noted
The analysis of the data makes it possible to predict the risk of injury to specific females by taking their ovarian cycle, dominance rank and age into account, as well as whether their social group is separating into two or more distinct groups.
Ovulating females are, for instance, twice as likely to be wounded as those who are in the less fertile days of their cycle. Such injuries occur in the context of reproductive competition through interactions with both adult males and females.
The injuries of lactating baboons were about 21 percent less likely to heal in a given time period than those of non-lactating females. This may be because lactating females are in poorer physical condition or have less energy in general. This influences how well a wound can heal, tissue is repaired and infections are curbed.
Murray has some sharp words for Millennials whose “sense of entitlement,” he claims, has made them reluctant to pay their dues doing menial tasks. He notes that many curmudgeons (read: bosses) are managers in their fifties and older who “were getting up at five in the morning to deliver newspapers when they were nine or ten” and may have worked their way through college doing hard physical work. Moreover, “when the curmudgeons in your life were twenty-two, most of them found that getting started in the job market was characterized by low pay, boring entry-level work, and little job security,” he writes.
As a result, they’re “hypersensitive to any vibe you give off when you’re told to go pick up something in the mailroom. You don’t have to say anything or even roll your eyes,” he writes. “The slightest of sighs will lodge in their memory like their first kiss, only in a bad way 黑頭粉刺.”
If all this makes curmudgeons sound tough to please, that’s because they usually are. But, Murray points out, there’s an important upside: They often make great mentors. To get ahead fast, he writes, “you want to be assigned to a successful curmudgeon, the more demanding the better 股星娛樂場.”
Why? Because, Murray writes, he or she is “more likely to have a gimlet eye for mistakes — and by the same token is more likely to notice when they don’t occur … and to be in love with excellent performance.” Deliver it, and your curmudgeonly boss is “your best bet to become your self-appointed advocate” to other higher-ups. And whose career, entry-level or not, couldn’t use one of those discounted gucci handbags?
An early theory of why babies enjoy peekaboo is that they are surprised when things come back afterreenex being out of sight. This may not sound like a good basis for laughs to you or I, with our adult brains, but to appreciate the joke you have to realise that for a baby, nothing is given.
They are born into a buzzing confusion, and gradually have to learn to make sense of what is happening around them. You know that when you hear my voice, I’m usually not far behind, or that when a ball rolls behind a sofa it still exists, but think for a moment how you came by this certainty.
The Swiss developmental psychologist Jean Piaget called this principle’object permanence’ and suggested that babies spent the first two years of their lives working it out. And of course those two years are prime peekaboo time.
Looked at this way, the game isn’t just a joke, but helps babies test and re-test a fundamental principle of existence:reenex that things stick around even when you can’t see them .Maybe evolution fixed it so that babies enjoy peekaboo for its own sake, since it proved useful in cognitivereenexdevelopment, but I doubt it. Something deeper than mere education is going on.
Gunmen have stormed Libya’s parliament, forcing MPs to abandon a vote on a new prime minister, officials say.
Correspondents say lawmakers left the building after hearing gunshots.
The attempted vote followed the resignation of Abdullah al-Thinni, who stepped down as prime minister earlier this month after he and his family were targeted by militiamen.

Earlier reports that several people had been wounded in the attack on Tuesday are unconfirmed 物業按揭.
It is unclear who was behind the disturbance 香港劇集.
