Convex subcomplexes of CAT(0) cubical complexes
In addition to Anton Petrunin's answer below, maybe also this paper is of interest: arxiv.org/abs/1211.1871 |

Group cohomology with compact support
Complementing Yemon Choi's comment: Maybe you mean Prop. 7.5 on p. 209 in Brown's book. |

Nice trick! Why don't you post it as a regular answer so that I can upvote and accept it? Question too easy? |

By permutation of the factors via the projection $B_k\rightarrow S_k$. |

Directed subposet of a poset containing the minimal elements
Thanks Paul for the keywords, I will have to look them up. I used the definition of E in the context of arxiv.org/abs/1407.5171 Definition 6.3. But I have the feeling that there is more behind that definition and that's why I'm asking. |

Directed subposet of a poset containing the minimal elements
Andreas, yes, there might be no minimal elements in $\{z:x<z>y\}$ and this set even might be empty. However, in my application, there is always at least one minimal element in that set. |
