Early Childhood Parenting Predicts Late Childhood Brain Functional Connectivity During Emotion Perception and Reward Processing

Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later.  相似文献

Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram     

Laura P. B. Partain 《Journal of International and Intercultural Communication》2020,13(3):216-237

ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.  相似文献   

Using the Information Structure Model to Compare Profile-Based Information Filtering Systems     

Yuval Elovici  Bracha Shapira  Paul B. Kantor 《Information Retrieval》2003,6(1):75-97

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.  相似文献

AMPK、能量代谢与运动的关系研究     

黄涛  孙海生  夏志 《吉林体育学院学报》2006,22(4):64-65

AMP激活的蛋白激酶（AMPK）不仅可以作为细胞水平的能量感受器，还可以通过细胞因子参与调节机体整体的能量消耗和能量摄人。运动等应激可以激活AMPK。参与调节骨骼肌葡萄糖代谢和脂肪酸氧化等能量代谢过程。运动训练可影响骨骼肌AMPK基因表达，进而参与到运动训练的机体适应机制。  相似文献
