The Taking of a Position: A Reinterpretation of the Elaboration Likelihood Model

This article explains how data associated with attitude change and persuasion in mainstream psychology and social psychology can be reinterpreted as evidence of the agentive ability of taking a position. A critical review is made of the elaboration likelihood model and a position model is adapted from positioning theory. The postulates of the elaboration likelihood model are then subjected to critical scrutiny by means of comparison with our position model. In this way regularities associated with attitude change and persuasion are interpreted as evidence of a deliberative process, involving negotiation and the use of supporting and opposing arguments. We present this as evidence of the commonly held agentive ability to position oneself and anticipate the positions of others.     

COLLECTION SALES: GOOD OR BAD FOR JOURNALS?

This article discusses the impact of collection sales (i.e., the bundling of several journals for sale by publishers to libraries) on journals. The advent of electronic journal distribution implies that bundling is an efficient sales strategy and can act to extend the reach of a journal. Current arrangements are discussed and shown to lead to tensions between commercial publishers and nonprofit journals. The article argues that nonprofit journals should not necessarily abandon collection sales programs. Rather, nonprofit journals may benefit from withdrawing from commercial publishers which distribute their own for-profit journals, and joining together to be distributed by less commercial publishers who set relatively low prices for their collections.

Scales Measuring General Evaluation with Minimal Distortion

Recent factor-analytic studies demonstrating marked concept-rater-scaleinteraction using evaluative semantic differential scales posea problem for opinion researchers who lack the time, money,subjects, or trained personnel to perform a pretest factor analysisas the basis for selecting reliable scales. In this study, 225raters drawn from 10 sub-populations rated 9 concepts on 39evaluative scales and 2 marker scales. When these data weresubjected to 19 different principal factor analyses based onvarious concept-rater combinations, 6 scales loaded above .60on the dominant first factor of all analyses, 9 additional scalesloaded above .50 on the same factor for all analyses, and 7scales failed only once to load above .50. These scales arerecommended for use as a measure of general evaluation undercertain conditions     

On a Unified Generalized Quasi–likelihood Approach for Familial–Longitudinal Non‐Stationary Count Data

Abstract. In this paper, conditional on random family effects, we consider an auto‐regression model for repeated count data and their corresponding time‐dependent covariates, collected from the members of a large number of independent families. The count responses, in such a set up, unconditionally exhibit a non‐stationary familial–longitudinal correlation structure. We then take this two‐way correlation structure into account, and develop a generalized quasilikelihood (GQL) approach for the estimation of the regression effects and the familial correlation index parameter, whereas the longitudinal correlation parameter is estimated by using the well‐known method of moments. The performance of the proposed estimation approach is examined through a simulation study. Some model mis‐specification effects are also studied. The estimation methodology is illustrated by analysing real life healthcare utilization count data collected from 36 families of size four over a period of 4 years.

用于研究细胞入侵的基质降解实验

在细胞正常发育、发炎和肿瘤转移研究中有一个关键步骤,就是通过多层的细胞外基质入侵细胞。在传统的研究方法中,研究者们已经发展了自己的检测方法,就是利用荧光标记的凝胶来研究基质降解,其中伴随着细胞的入侵。这篇文章探索了研究细胞入侵的新方法,能得到比传统方法更一致的结果。研究者们利用这些方法来研究降解时间过程,扫描在降解过程中潜在的活化剂或者抑制剂,探索细胞入侵的通道。
