Model selection for factor analysis: Some new criteria and performance comparisons

This paper derives Akaike information criterion (AIC), corrected AIC, the Bayesian information criterion (BIC) and Hannan and Quinn’s information criterion for approximate factor models assuming a large number of cross-sectional observations and studies the consistency properties of these information criteria. It also reports extensive simulation results comparing the performance of the extant and new procedures for the selection of the number of factors. The simulation results show the di?culty of determining which criterion performs best. In practice, it is advisable to consider several criteria at the same time, especially Hannan and Quinn’s information criterion, Bai and Ng’s IC_p2 and BIC₃, and Onatski’s and Ahn and Horenstein’s eigenvalue-based criteria. The model-selection criteria considered in this paper are also applied to Stock and Watson’s two macroeconomic data sets. The results differ considerably depending on the model-selection criterion in use, but evidence suggesting five factors for the first data and five to seven factors for the second data is obtainable.     

An Inquiry into Liberty,Slavery, and Thomas Jefferson’s Place in American Memory

Abstract

This article presents a guided inquiry into Thomas Jefferson’s place in American memory. It centers on Jefferson’s liberty-based articulations and his involvement in slavery, which are paradoxical when juxtaposed. Evocative primary sources and competing secondary sources ground the inquiry. Discipline-specific strategies direct students through the stages of inquiry. Close reading, text-based writing, and informed action intertwine with history literacy, historical thinking, and historical argumentation. Discussion focuses on logical curricular extensions.

Visibly ageing femininities: women’s visual discourses of being over-40 and over-50 on Instagram

Abstract

This article explores visual discourses about over-40 and over-50 femininities that emerge from women’s own Instagram accounts. It analyses women’s visual and textual rhetoric of what over-40 and over-50 looks like, and whether it could interrupt the ageist, sexist, and body-normative discourses of female ageing and visibility. Intertextual visual discourse analysis of images, captions, and hashtags reveals two dominant themes (fitness and fashion) and two repeating rhetorical elements (motherhood and self-sufficiency) through which women make themselves visible as over-40/50. A few explicitly subversive discourses (i.e., over-40 fatshion account) exist, but a discourse of a healthy, fit, fashionable, independent, self-sufficient, and happy mother over-40/50 is prevalent. It easily lends itself to being interpreted as an insidious reproduction of post-feminist ideology, but I argue that there are moments of critique and subversion within. Thus, a reparative reading that acknowledges moments of disconnect from the discourse that normalizes ageing women’s limited or non-existent visibility is offered.

Romantic Relationships and Criminal Desistance: Pathways and Processes

In dominant theories of criminal desistance, marital relationship formation is understood to be a key “turning point” away from deviant behavior. Empirical studies supporting this claim have largely focused on the positive role of marriage in men's desistance from crime, and relatively few studies have examined the role that nonmarital relationships may play in desistance. Drawing on 138 longitudinal in‐depth interviews with 22 men and women reentering society from prison, this article extends the scope of desistance research by additionally considering the significance of more fleeting and fluid relationships, and the diverse processes through which romantic relationships of all sorts are linked with criminal behaviors. We present an empirically based typology detailing six processes, grouped within three conceptual categories, through which romantic relationships had their effects. These pathways include material circumstances, social bonds and interactions, and emotional supports and stressors. We also consider gender differences in these processes. While more tenuous bonds to marginally conventional partners would seem to exert little effect, as one of the few relationships and social roles available to many former prisoners, we found that they wielded important influence, if not always in a positive direction.     

伊拉克战争与公众参与中国中东外交政策制定

伊拉克战争为公众参与中国中东外交政策制定提供了机会,参与群体前所未有地扩大,参与途径全面拓展,不同意见的表达开始涌现,公众主动对外交建言献策,开始有意施加民意压力。更为重要的是,公众意见开始成为外交部门对外传播国家主张的背景支撑和参考因素。公众因素开始成为中国制定中东外交决策时需要考虑的重要参数之一,但其影响力有限,更多是参考和制约作用,其影响正处于发展之中。
