In this article, I argue for the need of more use of exploratory techniques to identify dynamics in social interactions. I describe several approaches as they are applied to multivariate time series data. The first approach is an algorithm that searches for periods of variability and stability at the individual level as well as for patterns of overlap in such periods between the two individuals in a couple. These patterns describe the daily ups and downs in the couples' affect and are predictive of the state of the couples 1 to 2 years later. The second approach, hierarchical segmentation, is based on the idea of partitioning the time series in segments with distinct data patterns. In the case of data from dyads, as in the illustration, the patterns can be compared in terms of coherence between the 2 individuals in the dyad. The third approach is based on network analysis, and its use is shown as a method to examine data transitions at the individual and dyadic level as well as system-wide coherence in multivariate systems. For each approach, I provide examples of its use with empirical data. The article ends with general guidelines and recommendations for researchers interested in using exploratory methods as a way to examine psychological processes. 相似文献

In many longitudinal studies, self‐esteem has been shown to increase up until around age 50 or 60 and to decrease thereafter. These studies have also found substantial inter‐individual differences in the intra‐individual development of self‐esteem. In the current study, we examined whether this variation in change could be attributed to underlying latent classes of individuals following different trajectories of self‐esteem development over time. By applying general growth mixture modelling to data from the representative German pairfam study (N = 12 377), four latent classes of self‐esteem development across five years were extracted. Based on their mean levels, trajectories, and variability, individuals in the latent classes could be described as having (a) constant and stable high self‐esteem (29.00% of the sample), (b) constant but variable moderate self‐esteem (31.69%), (c) increasing and stabilizing self‐esteem (15.13%), and (d) decreasing and variable self‐esteem (24.18%). Furthermore, these latent classes differed in accordance with findings of prior research on self‐rated, partner‐rated, and objective correlates of the domains of health and well‐being, partner relationships, and occupational status. Thus, the current study shows that inter‐individual variation in intra‐individual change in self‐esteem is not random but reflects specific individual trajectories, or pathways, of self‐esteem.

An increasing number of public problems have been subject to market-based interventions as solutions. However, the relationship between problems and solutions in market-based interventions is complex. On occasions solutions are reformulated as understanding of the nature of the problem are advanced. Alternatively, problems are reconfigured to fit a standard solution. Or solutions are said to generate numerous new problems. The complex entangling of problems, solutions and markets can be explored by focusing on the field of online privacy. The complexities of this field can be analysed through three science and technology studies (STS) treatments of problems and solutions. First, issue-problematisation can be used to understand the ways in which a problem is assembled and comes to form the focus for discussion as an issue. Second, a paradigm-exemplar approach can assess the extent to which a particular coupling of problem and solution becomes an exemplar for others to draw on. Third, ontological constitution provides a focal point for analysing the ways in which the very nature of entities involved in problems, solutions and markets can be considered. There is analytic utility in each of these approaches in engaging with online privacy regulation and the emerging role of start-ups in introducing new privacy products to an emerging market place. However, these STS approaches leave us with questions regarding the relationship between market solutions and publics, the co-ordination of entities in market solutions and the normative questions that arise from entangling markets, problems and solutions. 相似文献

What actually happens inside genetic databases, how do they work upon data and who does this work? While they have become central tools for doing science, not much is known about the work that goes on inside these vital infrastructures. Ethnographic explorations of two of the world’s largest nucleotide sequence databases, GenBank and the European Molecular Biology Laboratory’s EMBL-Bank, reveal manifold goings-on. Like most infrastructural work, it is modest and invisible routines that build and maintain the vast interconnected suite of bioinformational resources. Data curators construct organisms out of sulphuric sludge, dataflow engineers as self-styled “genetic information plumbers” keep the data deluge flowing, and a data submissions support assistant manages to make room for care amidst this deluge. Taken together, these data labours render tangible the modest and processual aspects of data infrastructure while also revealing the databases to be situated and lively spaces of convergence. Inventively analysing data labours paves surprising ways for encountering and making sense of databases, data and the work they do. Here, practices of natural history, like specimen-making and curation, are continued by other means while the assembly of sludge sheds light on the absences and deletions which mystify infrastructural maintenance work. 相似文献

Clustering individuals by measures of similarity or dissimilarity at trajectories of changes in longitudinal data enables determination of typical patterns of development and growth. The present research proposes a new constrained k‐means method with lower bound constraints on cluster proportions and distances among clusters at focused variables and time points to fulfill various needs in clustering longitudinal data. The method assumes a large number of clusters at the onset and iteratively deletes and combines clusters according to these constraints. An additional property of the proposed constrained k‐means includes direct estimation of the unknown number of clusters. Simulation results clearly show the usefulness of the method for extracting clusters in plausible, real‐life analysis including non‐normality within clusters, and the proposed algorithm works well and convergence of the estimates is satisfactory. An actual example using Japanese longitudinal data regarding sleep habits and mental health is presented to verify the utility of the proposed constrained k‐means. 相似文献

AbstractThe last US government survey that collected information on religious identification was in 1957. Since then researchers have relied solely on non-governmental data sources, primarily the General Social Survey. This paper shows how the American Religious Identification Survey (ARIS) series has deepened understanding of religious identification in the past two decades with its large samples (113?713 in 1990, 50?280 in 2001, and 54?461 in 2008) and its unique open-ended religion question. Giving respondents a chance to name their own religion, if any, allows researchers to identify and study small religious groups, which are placed together under ‘other’ in typical national studies. By using a consistent research methodology, the ARIS surveys form a time-series that enable tracking trends. The paper describes two case studies: how the ARIS series documented the rise of the Nones and how it tracked shifts in religious identification among American Latinos. 相似文献

马尔科夫蒙特卡洛（MCMC）是项目反应理论中处理缺失数据的一种典型方法。文章通过模拟研究比较了在不同被试人数,项目数,缺失比例下两种MCMC方法（M-H within Gibbs和DA-T Gibbs）参数估计的精确性,并结合了实证研究。研究结果表明,两种方法是有差异的,项目参数估计均受被试人数影响很大,受缺失比例影响相对更小。在样本较大缺失比例较小时,M-H within Gibbs参数估计的均方误差（RMSE）相对略小,随着样本数的减少或缺失比例的增加,DA-T Gibbs方法逐渐优于M-H within Gibbs方法 相似文献
