材料科学技术转型发展与钢铁创新基础设施的建设

摘要：在第4次工业革命浪潮的推动下,钢铁科学与技术正在经历数字化、智能化转型。钢铁行业全流程各工序均为“黑箱”,为多场、多相、多变的巨系统,具有复杂相关关系和遗传效应等。这些不确定性带来了巨大的挑战。挑战和机遇并存。这些不确定性提供了智能化和数字化技术的应用场景资源;钢铁行业极为丰富的大数据提供了挖掘其中蕴含客观规律的数据资源;现代的数据科学、智能技术为解决不确定性问题提供了强大的手段。以数据为中心,以工业互联网为载体,以实验工具、数字数据、计算工具为支撑,建设钢铁企业材料创新基础设施,将可以大幅度提高研发效率,降低研发成本,有力地支撑钢铁材料科学与技术的转型发展。实验工具平台除了传统的实验室仪器装备和中试装备之外,实际生产线被作为主要的实验工具。这些实验工具提供丰富、精准、写实的历史数据和现实生产数据,特别是生产线装备提供实际生产大数据,蕴含着生产过程中的全部规律,是极宝贵的数据资源。利用机器学习、深度学习等现代数据挖掘技术为计算工具,对这些数据资源进行处理、分析、计算,将数据转换为高保真度模型,可以得到具有“原位分析能力”的数字孪生。在工业互联网的总体架构下,以数字孪生为核心,组成信息物理系统,构建起基于数据自动流动的状态感知、实时分析、科学决策、精准执行的闭环赋能体系,解决生产制造、应用服务过程中的复杂性和不确定性问题,提高资源配置效率,实现资源优化,对材料行业转型发展提供关键技术支撑。虚实映射、实时交互、精准控制的信息物理系统与材料创新基础设施合二为一,以材料创新基础设施为基盘,形成具有“原位分析能力”的数字孪生,建设钢铁生产全流程、一体化的信息物理系统,必将推进钢铁行业智能制造蓬勃开展和数字化、智能化转型。     

Status and solidarity in social comparison: Agentic and communal values and vertical and horizontal directions.

Social comparison involves positioning the self relative to others on a vertical or status dimension (ranging from upward to downward comparisons) and a horizontal or solidarity dimension (ranging from contrastive to connective comparisons). Across 3 studies in which 389 undergraduates recorded everyday social comparisons (n = 4,417), downward and connective comparisons were rated as more helpful and mood enhancing than upward and contrastive comparisons. The effects of horizontal comparisons were greater for people for whom solidarity was an important value; however, the effects of vertical comparisons were not greater for people who valued status. The roles of the comparison target, topic, and situation were also explored; for example, noticing undesirable features of the target enhanced status but undermined solidarity.

Praise and Blame and Robinson.

Daniel Robinson suggests that much of the civil and criminal law "serves as the institutionalized form of praise and blame". Indeed it does. Pulling at this thread of Robinson's tapestry leads the reader straightaway to a host of truths about how law and morality not only intersect, but work together in harmony. "[L]aw", Robinson says, is a "vivid expression of deeper and impenetrably complex moral theories". This essay explores several of these harmonies, but focuses on two. One is that political society must be seen as the cooperation of free persons according to law, which persons hold common moral understandings. The second has to do with retribution as the moral justifying aim of punishing criminals. The author goes beyond Robinson's limited praise of retribution, and shows that some central features of our practice of punishment are understandable only within the retributive framework.

Voices of fear and anxiety and sadness and depression: The effects of speech rate and loudness on fear and anxiety and sadness and depression.

Two studies investigated the role of expressive vocal behavior (specifically, speech rate and loudness) in fear and anxiety and in sadness and depression. In the 1st study, participants spoke about personally experienced fear and anxiety-arousing and neutral events using 3 different voice styles: fast and loud, normal, and slow and soft. In the 2nd study, participants spoke about personally experienced sad or depressing and neutral events using the same 3 voice styles. In both studies, the participants' highest levels of subjective affective and cardiovascular (CV) arousal occurred when they spoke about the emotional events in a mood-congruent voice style: fast and loud in the case of fear and anxiety, and slow and soft in the case of sadness or depression. Mood-incongruent voice styles canceled the heightened levels of CV arousal normally associated with these negative emotions. The voice-style manipulation had no significant effect on the participants' levels of CV arousal during the neutral discussions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Aging and negative affect: The rise and fall and rise of anxiety and depression symptoms.

The relationship between aging and negative affect is dynamic and complex. Although prior studies have often cited lower prevalence rates of anxiety and mood disorders among older individuals, these studies may miss the dynamic relationship between symptoms and aging. To evaluate a nonlinear model of the relationship between aging and negative affect, the author examined measures of neuroticism, anxiety, and depression symptoms in a cross-sectional, community sample (N = 335), ages 18 to 93. Results indicated a curvilinear relationship, with mean symptom levels increasing during early adulthood (until the mid-30s) and then showing a small decline until older adulthood (the mid-70s), when symptoms again increase with age.
