原创研究年轻人夜间大脑活动指纹状模式也出现在老年人身上
目的：定量睡眠脑电图被视为脑电图“指纹”，即它在个体内稳定但个体之间有差异。然而，到目前为止，几乎所有针对这方面的研究都是在年轻男性中进行的。因此，很想知道睡眠脑电图指纹概念是否适用于男女老年人样本。患者和方法：从三个不同子样本（每个子样本 30 名健康个体）获得的数据被重新用于当前的二次分析（年轻男性（YM）= 25.6 ± 2.4 岁，老年男性（EM）= 69.1 ± 5.5 岁，老年女性（EW）= 67.8 ± 5.7 岁）。个体在睡眠实验室中睡了十次，总共进行了 900 个研究夜晚。然而，为了避免因干预相关的睡眠脑电图功率谱变化而导致的误解，仅包括没有任何干预的 3 个假性睡眠夜，将数据集减少到 270 个。为了确定假性睡眠夜对之间 NREM 睡眠脑电图功率谱的稳定性，分别按样本计算受试者内和受试者之间的曼哈顿距离测量值。结果：无论是子样本还是假性睡眠夜对，在受试者内功率谱比较中都观察到最低距离测量值，即最大相似度（EW 的平均距离测量值范围为 3.82 至 4.06，EM 的平均距离测量值范围为 3.55 至 3.63，YM 的平均距离测量值范围为 3.04 至 3.62）。此外，样本之间的个体内相似度没有显着差异。受试者之间的功率谱距离测量值明显较大（EW 的平均距离测量值范围为 12.95 至 13.15，EM 的平均距离测量值范围为 12.21 至 12.57，YM 的平均距离测量值范围为 10.33 至 10.78），且年轻人和老年人之间存在显著差异。结论：本研究结果支持以下观点：睡眠脑电图功率谱是一种类似于个人特征的特征，直到老年仍保持独特性。这一发现可能有助于提高测量干预效果的灵敏度。关键词：睡眠脑电图功率谱、衰老与睡眠、睡眠脑电图的遗传性、脑电图指纹、类似于特征的定量脑电图特征、睡眠脑电图的个体性

Addressing the skills challenge will require interventions across the skills landscape and it was interesting to note that companies identified the importance of multiple skills development pathways. As may be expected, university routes have been identified as most critical but there was also significant demand for alternative routes such as apprenticeships, internships and CPD training. Interestingly, appetite for these alternative routes was more evident among larger companies, reflecting not just their demand for such routes but also their own experience in utilising them. Smaller companies were less inclined towards non-university routes, indicating that work needs to be done to communicate the value of these pathways for all companies, large or small.
Union Investment's climate strategy
The European Union has set itself the goal of channelling financial flows into sustainable investments, for example with the Disclosure Regulation and the taxonomy. Asset managers will therefore also have to make their financial products more sustainable. Unlike investors in the equity and bond markets, who can focus on more sustainable companies and countries, Union Investment Real Estate, as the shareholders of the properties themselves, is responsible for implementing the legal climate protection requirements. In order to meet the requirements and avoid write-down risks due to stranded assets, we are continuously optimising our real estate portfolio. In doing so, we not only take into account transitory climate risks, but also the physical effects of climate change, such as storms and flood disasters.

Market Size and Institutions in a Global Economy∗
1 Another important piece of evidence is the Atlantic trade, as shown by Acemoglu et al. ( 2005 ). Even though they emphasize the role of the differential medieval institutions among Atlantic traders (England and the Netherlands vs. France, Portugal, and Spain) in their subsequent institutional reforms, the rise of Atlantic trade due to the breakthrough in navigation is the precondition for these institutional reforms. Namely, when the economic benefits of institutional reforms were higher for Atlantic traders than for the rest of Europe, the reforms were more likely to occur there. The fact that non-Atlantic-trader European nations also made their reforms much earlier than the rest of the world may also be due to the growing neighboring markets, in addition to competition and the spread of knowledge.
