A primal dual active set with continuation algorithm for high-dimensional nonconvex SICA-penalized regression

The smooth integration of counting and absolute deviation (SICA) penalty has been demonstrated theoretically and practically to be effective in nonconvex penalization for variable selection and parameter estimation. However, solving the nonconvex optimization problem associated with SICA penalty in high-dimensional setting remains to be enriched, mainly due to the singularity at the origin and the nonconvexity of the SICA penalty function. In this paper, we develop a fast primal dual active set (PDAS) with continuation algorithm for solving the nonconvex SICA-penalized least squares in high dimensions. Upon introducing the dual variable, the PDAS algorithm iteratively identify and update the active set in the optimization using both the primal and dual information, and then solve a low-dimensional least square problem on the active set. When combined with a continuation strategy and a high-dimensional Bayesian information criterion (BIC) selector on the tuning parameters, the proposed algorithm is very efficient and accurate. Extensive simulation studies and analysis of a high-dimensional microarray gene expression data are presented to illustrate the performance of the proposed method.     

Education and wage inequality in the informal sector: The case of Cameroon

This article analyses the effects of education on wage inequality in the informal sector in Cameroon. The author uses quantile regression on data from the Second survey on employment and the informal sector in Cameroon (EESI 2) of 2010. The results indicate that both wages and wage inequality increase with education in the informal sector, with tertiary education creating greatest inequality. These findings point to a number of policy recommendations for a transition to formality, such as the creation of more jobs for a skilled workforce, the development of sites adapted to informal sector activities and the creation of more vocational schools.     

Resistance as Sacrifice: Toward an Ascetic Antiracism

Often described as an outcome, inequality is better understood as a social process—a function of how institutions are structured and reproduced, and the ways people act and interact within them across time. Racialized inequality persists because it is enacted moment to moment, context to context—and it can be ended should those who currently perpetuate it commit themselves to playing a different role instead. This essay makes three core contributions. First, it highlights a disturbing parity between the people who are most rhetorically committed to ending racialized inequality and those who are most responsible for its persistence. Next, it explores the origin of this paradox—how it is that ostensibly antiracist intentions are transmuted into “benevolently racist” actions. Finally, it presents an alternative approach to mitigating racialized inequality, one that more effectively challenges the self‐oriented and extractive logics undergirding systemic racism, rather than expropriating blame to others, or else adopting introspective and psychologized approaches to fundamentally social problems, those sincerely committed to antiracism can take concrete steps in the real world—actions that require no legislation or coercion of naysayers, just a willingness to personally make sacrifices for the sake of racial justice.     

中国智能经济的涌现机制

我国智能经济的发展内生于经济转型升级过程中创造的智能化需求。与AI 1.0不同,新一代人工智能(AI 2.0)不再是简单用计算机模拟人的智能,而是基于网络空间发展的数据智能,即智能机器、人和网络相互融合的智能系统。智能经济是以数据和计算为“关键生产要素”的新经济形态,包括人工智能的产业化和产业的智能化过程中创造的新产品、新技术、新模式和新业态。互联网,尤其是移动互联网发展中创造出的数据生态优势是中国人工智能科技产业发展的前提和基础。在拥有数据生态优势的条件下,强烈的需求牵引、产学研协同创新、创新生态系统的高度开放性和核心产业部门与融合产业部门的融合发展,共同构成了中国智能经济发展的关键机制。     

鲍德里亚的消费经济批判及其艺术性变革

在鲍德里亚看来,当代社会在经济现象形态方面表现为消费经济的活跃,需要进行符号经济学批判。当代消费经济具有独特的运行机制,是将各种商品都转化为符号体系的过程,这既是资本的进一步扩展、资本增值的实然逻辑,又是技术理性的渗透、媒介信息的传播,还是物体系的形成、拜物教的深化。消费经济及其奢侈文化从大都市扩散到世界各地,推动了当代商业的发展。当代消费经济令人与人之间关系冷漠,围绕人的不再是实际物品,而是众多意义,需要用结构主义符号学分析其运行机制,采用艺术性变革的方式消除消费异化。艺术能够建构具有救赎作用的乌托邦,不应只为了满足感官刺激,而要通向真理之路,唤醒人的创造潜能,改造消费社会的不合理机制。

人口较少民族经济向现代经济转变的路径分析

在阐述路径依赖理论的基础上,结合人口较少民族经济的特点对人口较少民族经济向现代经济转变的路径进行了分析,提出要辩证地看待人口较少民族传统经济在这一转变中的影响和作用,认为人口较少民族实现经济转变的首要问题是打破经济封闭和信息封闭,在此基础上,将自身的特色优势与区域优势有效结合起来,将传统经济中的积极因素与现代经济因素有效结合起来,走因地制宜、循序渐进的转变路径。     

论我国社会主义市民社会的培育

摘要：市民社会理论虽源于西方,但是随着中国社会经济的发展,市民社会主体的形成等因素的出现,社会主义市民社会在中国的发展已经成为必然。我国的传统制度和文化排斥市民社会的发展,因而培育我国社会主义市民社会就要破除社会主义市民社会发展的阻碍因素。在发展经济和稳定的政治条件下,培育社会主义市民社会要从市场经济、民主政治、公民的市民社会意识以及文化系统等方面努力。
