某写字楼工程,地下1层,地上15层,框架一剪力墙结构。首层中厅高12m,施工单位的项目部编制的模板支架施工方案是满堂扣件式钢管脚手架,方案由项目部技术负责人审批后实施。施工中,某工人在中厅高空搭设脚手架时随手将扳手放在脚手架上,脚手架受振动后扳手从上面滑落,顺着楼板预留洞口(平面尺寸0.25m×0.50m)砸到在地下室施工的王姓工人头部。由于王姓工人认为在室内的楼板下作业没有危险,故没有戴安全帽,被砸成重伤。

Pretty in pink: adult women do not remember being so obsessed with the colour, yet it is pervasive in our young girls’ lives. It is not that pink is intrinsically bad, but it is such a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repeatedly and firmly fuses girls’ identity to appearance. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidence of innocence. Looking around, l despaired at the singular lack of imagination about girls’ lives and interests.

Girls’ attraction to pink may seem unavoidable, somehow encoded in their DNA, but according to Jo Paoletti, an associate professor of American Studies, it is not. Children were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What’s more, both boys and girls wore what were thought of as gender-neutral dresses. When nursery colours were introduced, pink was actually considered the more masculine colour, a pastel version of red, which was associated with strength. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolised femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children’s marketing strategy, that pink fully Came into its own, when it began to seem inherently attractive to girls, part of what defined them as female, at least for the first few critical years.

I had not realised how profoundly marketing trends dictated our perception of what is natural to kins, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts developed after years of research into children’s behaviour: wrong. Turns out, according to Daniel Cook, a historian of childhood consumerism, it was popularised as a marketing trick by clothing manufacturers in the 1930s.

Trade publications counselled department stores that, in order to increase sales, they should create a "third stepping stone" between infant wear and older kids’ clothes. It was only after "toddler" became a common shoppers’ term that it evolved into a broadly accepted developmental stage. Splitting kids, or adults, into ever- tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differences—or invent them where they did not previously exist.

The author suggests that our perception of children’s psychological development was much influenced by()

A. the marketing of products for children

B. the observation of children’s nature

C. researches into children’s behavior

D. studies of childhood consumption
