Digital Module 16: Longitudinal Data Analysis

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module begins with a nontechnical overview of longitudinal data analyses drawing distinctions with cross-sectional analyses in terms of research questions to be addressed. Nuances of longitudinal designs, timing of measurements, and the real possibility of missing data are then discussed. The three interconnected components of the LME model—(1) a model for individual and mean response profiles, (2) a model to characterize the covariation among the time-specific residuals, and (3) a set of models that summarize the extent that individual coefficients vary—are discussed in the context of the set of activities comprising an analysis. Finally, they demonstrate how to estimate the linear mixed effects model within an open-source environment (R). The digital module contains sample R code, diagnostic quiz questions, hands-on activities in R, curated resources, and a glossary.

关于我国离婚法定条件的探讨——混合标准还是单一标准

关于离婚法定条件的探讨贯穿于我国婚姻法发展的整个过程。从1950年新中国第一部婚姻法到1980年婚姻法的重新制定,乃至2001年婚姻法的修订,都是一个探索的过程,但探索的结论并没有很大的突破,仍是将离婚法定条件定为感情或婚姻破裂的单一标准。出于完善我国婚姻立法中的法理基础的需要,笔者以为应在我国婚姻立法中确立混合标准的离婚法定条件。

"梦诗":陆游爱国情怀的另一种表达

分析陆游“梦诗”中所表现出来的深沉的爱国意蕴,解读他在苟安于一隅的南宋朝廷统治下虽无法实现光复国土的伟大抱负却始终抱有心系祖国安危、民族复兴的高尚情怀。“梦诗”的笔调是浪漫的,也是悲愤的;“梦诗”的内容有虚构的,更多的却是纪实。在“梦”这一荒诞的形式中流露出来的是陆游终身无法释怀的爱国情结。

Bursting paradigms: a colour wheel of practice-research

ABSTRACT

In this article, I question practice as a research paradigm by exploring its position in relation to non-positivist qualitative methodologies. Frayling’s [1994. Research in art and design. Royal College of Art Research Papers, 1(1), 1993/4] distinctions between research into, through, and as (for) practice are expanded to explore overlaps between these approaches. I argue for the need to understand the nuances of different epistemologies and ontologies that underpin diverse disciplinary approaches to practice-research. This is done through an analysis of a selection of Arts and Humanities Research Council (AHRC)-funded projects to find out how they are using and/or embedding practice in the research process. The resulting Colour Wheel of Practice-Research illustrates a spectrum of positions of practice in relation to research, suggesting existing research paradigms are bursting at the seams and that the “disciplinary matrix” of practice might offers other ways of knowing. The reason I have chosen to focus primarily on AHRC-funded projects is because it explicitly states its support of “practice-led research” and that it “remains dedicated to this area of research”. This article aims to add to knowledge of how and why practice-research is of continuing interest to research councils, universities, and those identifying as practice-based/led researchers.
