This paper is situated in interaction on the Internet and presents an analysis of chat conversations in Romance languages--French, Italian, Portuguese and Spanish--between students from several universities. The Internet is currently a fertile setting for intercultural and plurilingual encounters, and interaction, virtual or real, is seen as a…

The author was invited to prepare a commentary in response to the Lev-Wiesel manuscript titled "Intergenerational Transmission of Sexual Abuse? Motherhood in the Shadow of Incest." Lev-Wiesel's stated intent in the study was to understand an important issue, namely how is intra-familial sexual abuse perpetuated across successive generations. This…

This study examined infants' use of object knowledge for scaling the manipulative force of object-directed actions. Infants 9, 12, and 15 months of age were outfitted with motion-analysis sensors on their arms and then presented with stimulus objects to examine individually over a series of familiarization trials. Two stimulus objects were used in…

This article reports a reliability study of two versions of the Vocabulary Levels Test at the 5000 word level. This study was motivated by a finding from an ongoing longitudinal study of vocabulary acquisition that Version A and Version B of Vocabulary Levels Test at the 5000 word level were not parallel. In order to investigate this issue,…

By using the Rasch model, much detailed diagnostic information is available to developers of survey and assessment instruments and to the researchers who use them. We outline an approach to the analysis of data obtained from the administration of survey instruments that can enable researchers to recognise and diagnose difficulties with those…

The analysis of a Murder case study can be used in general chemistry or nonscience major chemistry courses to teach data handling and analysis in a non-laboratory context. This case study will help students to respond more enthusiastically and with more interest to a set of material placed before them related to a real case rather than…

In this article, we deal with students' algebraic generalizations set in the context of elementary geometric-numeric patterns. Drawing from Vygotsky's psychology, Leont'ev's Activity Theory, and Husserl's phenomenology, we focus on the various semiotic resources mobilized by students in their passage from the particular to the general. Two small…

Properties of the Spearman correction for attenuation were investigated using Monte Carlo methods, under conditions where correlations between error scores exist as a population parameter and also where correlated errors arise by chance in random sampling. Equations allowing for all possible dependence among true and error scores on two tests at…

R. Kliegl, A. Nuthmann, and R. Engbert reported an impressive set of data analyses dealing with the influence of the prior, present, and next word on the duration of the current eye fixation during reading. They argued that outcomes of their regression analyses indicate that lexical processing is distributed across a number of words during…

Experimental research involves comparing two or more conditions. One of those conditions in single subject research is often the baseline. Adequate description of the baseline conditions is necessary for evaluating the effects of independent variables, drawing generalizations from studies, and providing information for subsequent replication…

Background: Large-scale coach education programs have been developed in many countries around the world to help prepare coaches for their important role. Coaches have said that they also learn to coach from experience, starting from when they were young athletes until their current coaching positions. Finally, in the last decade, Internet…

A simple experiment, the determination of the density of a liquid by several methods, is presented. Since the concept of density is a familiar one, the experiment is suitable for the introductory laboratory period of a first- or second-year course in physical or analytical chemistry. The main objective of the experiment is to familiarize students…

Social scientists remain unsure as to whether divorce acts to alleviate domestic violence or whether ex-spouses become the targets of the displaced violence. Using data from the National Incident-Based Reporting System and the Census, this study investigates the relationship between the divorce rate and the domestic crime rate. The study…

A few years ago, the University of Pennsylvania's Division of Human Resources began a data-based approach to the development of strategic plans and the measurement of programmatic effectiveness. One of its more successful endeavors in this area has been the creation of an HR scorecard that compares and contrasts individual school or administrative…

The general steps in conducting an evaluation using an online survey are the same as in using other methods: planning, data collection, data analysis, reporting, and application. Even though the process of evaluation using Internet-based surveys begins in a familiar manner, the unique requirements of the online methodology become apparent almost…
