Globally, conflicts are propelled by several factors including struggle for scarce and diminishing resources, climate displacements, systemic/social injustices and inequalities, differences in values and interests as a result of cultural orientation, political/class antagonism, unequal power relations, psycho-political pathologies, dynamics of misperceptions and identity crisis of political leaders, reform contradictions, youth unemployment and frustration.
▶ Information on the price expectations of businesses who are, after all, the price setters is particularly scarce (Bernanke, 2007) ▶ Evidence from surveys of firms substantially different from professional forecasters and households (Candia et al., 2022) → Firms may learn from their surroundings/network and assign an aggregate value to local signal (Lucas, 1972)
SUMMARY: - Global population is expected to increase from roughly 7.7 billion to nearly 10 billion by 2050 - Demand for cereals to be used as food for both humans and animals may grow to roughly 3 billion tonnes by that point from about 2 billion tonnes as of 2009 - Agricultural systems must better address climate change, water and land resources that are becoming scarce - Food companies must adapt to shifting consumption patterns, and play a greater role in promoting health and健康。资料来源:世界经济论坛,2021
我们提出了EN3D,这是一种增强的生成方案,用于雕刻高质量的3D人体化身。Unlike previous works that rely on scarce 3D datasets or limited 2D collec- tions with imbalanced viewing angles and imprecise pose priors, our approach aims to develop a zero-shot 3D gen- erative scheme capable of producing visually realistic, ge- ometrically accurate and content-wise diverse 3D humans without directly relying on pre-existing 3D or 2D assets.为了应对这一挑战,我们引入了精心制作的工作流量,该工程实现了准确的物理建模,以从合成2D数据中学习增强的3D生成模型。在推断期间,我们集成了优化模块,以弥合现实的外观和粗3D形状之间的差距。特定于EN3D包含三个模块:一个3D发电机,可以准确地对可概括的3D Humans建模具有合成,多样和结构化的人类图像的逼真外观的可概括的3D Humans;几何雕塑家
开放教科书在第一单元介绍了资本主义革命。虽然一些经济学教科书介绍共产主义及其向资本主义过渡的历史并不罕见,但大多数最新教科书的第一单元(或章节)都是关于什么是经济学?或经济学原理/基础。作者在第一单元介绍共产主义和资本主义的方法可能更适合宏观经济学,而不是微观经济学。因此,我建议教科书的标题应该是 CoreMacroEcon 而不是 CoreEcon 。鉴于经济学的定义——研究社会如何分配稀缺资源和商品,开放教科书介绍社会(或国家)如何分配稀缺资源以及经济主体(消费者、企业和政府)如何在市场中互动可能更合适。
认知资源,但就像生产军舰的经济一样,随着经验的积累,它会学会更好、更有效地运作(Haier 等人,1992 年)。与黄油到枪支的转变类似,这一过程通常涉及将心理生产从通用但稀缺的认知资源(如工作记忆)转移到高通量的专门能力(如感知;Schneider & Shiffrin,1977 年)。事实上,国际象棋专家与新手的区别之一是他们学会了看清位置的相对强度,使他们能够将缓慢、速率受限的认知能力(例如前向模拟)集中在最有希望的打法上(Chase & Simon,1973 年;De Groot,2014 年)。我们认为,经济和大脑中适应性资源分配之间的这种相似性并非巧合,而是反映了一个更深层次的事实:两者本质上都是生产系统,必须灵活地重新分配稀缺资源以追求不断变化的目标。在这封信中,我们提出,从心理生产和心理资源的角度看待认知系统是认知科学最有前途的前进道路之一。将心智视为稀缺心理资源的管家为认知科学和经济学之间的智力交流开辟了新的机会,并构成了当代认知科学研究许多最有前途的领域的基础,我们将在下面概述其中的一些领域。
