The Cox–Aalen model for left-truncated and right-censored data

We analyze left-truncated and right-censored (LTRC) data using an additive-multiplicative Cox–Aalen model proposed by Scheike and Zhang (2002), which extends the Cox regression model as well as the additive Aalen model. Based on the conditional likelihood function, we derive the weighted least-squared (WLS) estimators for the regression parameters and cumulative intensity functions of the model. The estimators are shown to be consistent and asymptotically normal. A simulation study is conducted to investigate the performance of the proposed estimators.

Proportional hazards regression with interval-censored and left-truncated data

This paper considers the estimation of the regression coefficients in the Cox proportional hazards model with left-truncated and interval-censored data. Using the approaches of Pan [A multiple imputation approach to Cox regression with interval-censored data, Biometrics 56 (2000), pp. 199–203] and Heller [Proportional hazards regression with interval censored data using an inverse probability weight, Lifetime Data Anal. 17 (2011), pp. 373–385], we propose two estimates of the regression coefficients. The first estimate is based on a multiple imputation methodology. The second estimate uses an inverse probability weight to select event time pairs where the ordering is unambiguous. A simulation study is conducted to investigate the performance of the proposed estimators. The proposed methods are illustrated using the Centers for Disease Control and Prevention (CDC) acquired immunodeficiency syndrome (AIDS) Blood Transfusion Data.     

The resentful undergrowth of nostalgia: Ontological insecurity,relative deprivation and powerlessness

This article untangles competing conceptualisations of nostalgia and identifies a specific form of collective-restorative nostalgia as politically significant. We argue that the link between resentment and this type of nostalgia emerges from their joint critique of the socio-political realities of the present. Nostalgia provides spatial and temporal orientations for a group's experiences of resentment through highly selective recollections of the heartland and an idealised golden age. We hypothesize that nostalgia leverages the heartland and the golden age to formulate claims for recognition and restored status on behalf of those who feel left behind by late modernity. Next, the article uses structural equation modelling and the 2019 Belgian National Election Study to reveal how resentment (consisting of ontological insecurity, group relative deprivation, and powerlessness) mediates between structural characteristics and nostalgia. Our findings suggest that each component of resentment individually contributes to explaining the nostalgia of less educated and economically deprived individuals.

论左翼作家之政治趋向

在残酷的历史时代背景下,马克思主义社会化、世俗化、大众化作为仁人志士特别是先进知识分子的救国使命,决定了左翼文学突出的政治倾向。表现在三个方面:个体趋向群体、社会价值疏淡文学价值、"社会化"倾向加重。本文着眼于政治文化,通过文学与政治之关系探讨来解析左翼文学政治化倾向的因由和影响,力求真实再现其历史本貌和本质。左翼文学作家的政治化倾向客观上限制了对艺术本质探索和审美追求,以及艺术个体自我的个性发挥,但在救亡图存的时代对于贫穷落后的平民文学,左翼作家却做出了历史性的功绩,对文学的大众化、平民化做出了不可磨灭的贡献。     

浅析农村留守未成年人监护制度

随着社会经济的快速发展，农村到城市务工人员不断增长，相对应的农村中的留守未成年人也在不断增多。由于缺少必要的监护，农村留守未成年人所引发的社会问题也随之不断增多。例如，留守未成年人的抚养问题、教育问题、监护问题、犯罪问题，等等，并已引起国家和社会的广泛关注。立足于我国农村留守未成年人权利保护现状，配之以对我国法律相关规定的分析，适度考量国外相关方面的立法，探索既适合我国国情，同时有利于保护留守未成年人权利的监护制度，以丰富我国的农村留守未成年人监护制度。     

也谈“左”“右”和“左右”——兼与王希杰先生商榷

人类左、右的分工很早就有,一般的都是右手有利,从左、右引申出的相关意义也是"左贬右尊",但在汉语中为何"左前右后",是否违背了人类的认知规律?文章从左、右的汉字结构,语言使用中"右"、"左"的引申含义及左手和右手在使用过程中的差异等三个方面探讨了"左前右后"的原因,指出汉语中的"左前右后"并没有违背人类语言的认知性原则--首位原则.     

《高兴》：“左翼”之外的“底层文学”

文学与时代的关系一直是文学研究的重大主题，《高兴》再一次提出了这一严峻的问题。在“左翼”式的“底层文学”标准参照下，《高兴》独特的典型形象、思想资源以及人物关系值得研究界重视。就此而言，贾平凹提供了“底层文学”一种新的方式，即在“美学”与“道德”之间，在不伤害“文学”的“可能性”的基础上，探索对大时代的讲述。
