Where 在具体例子中分别做什么成份？

(1) I have every confidence in your wisdom except where this sort of thing is concerned. 除了相关的这类事情，我对你的智慧很有信心。

【答】except是介词，where this sort of thing is concerned 是名词性从句，作except 的宾语。在介词后跟wh-word 引导的名词性从句，这在英语中很常见。又如：

He is everywhere except where he ought to be.  他到处露脸，只是不在他该在的地方。

Bamboo grows well except where it is cold and dry.  竹子除了在寒冷、干旱的地方外,长得很好。

I take a walk every day except when it rains. 除非下雨，我每天都要散步。

He's ready to offer his help except when he's busy. 除了忙的时候之外,他是愿意帮助人的。

(2) Hour-by-hour logs kept by thousands of volunteers over the decades have shown that, in theU.K., working hours have risen only slightly in the last 10 years, and in theU.S., they have actually fallen—even for those in professional and executive jobs, where the perceptions of stress are highest.  几十年来由数千名志愿者所作的钟点日志表明，英国在最近十年中工作时间只略微增加，而在美国，即使对工作压力最大的专业人士和管理人员而言，工作时间实际上减少了。

【答】在你的译文中，where the perceptions of stress are highest，没有翻译出。这实际是一个非限制性定语从句，修饰jobs。意为：“在这些工种（职业）里面，压力感是最高的。”

 where the perceptions of stress are highest 为非限制性定语从句，修饰前面先行词jobs"

这两个where分别引导什么从句呢？能针对性的解答吗？

请问老师，第1) 句中where引导条件状语从，指的是“除了这方面的智慧(except where)”。第2）句中 where引导定语从句,此时where 等于in which。所以可变成 …even for those in professional and executive jobs, in which the perceptions of stress are highest. 上述分析对吗？
