The relationship between multiple identity attributes and diversity, and individual decision making and group performance: experimental evidence.
… favoritism toward similar others. In addition, homogeneous groups outperformed diverse groups in tasks that were characterized by high interdependence when communication between group members was not allowed, but diverse groups outperformed homogeneous groups in the same tasks when communication …

An Analysis of Variables That Influence Stakeholder Participation and Support for Sustainable Tourism Development in Rural North Carolina
… any differences between stakeholders so that homogeneous groups can be identified. The second was what variables influence stakeholders' support for or against the development of sustainable tourism in a rural community? The third question was what variables influence a stakeholder's active or …

Clustering Profiles in Generalized Linear Mixed Models Settings Using Bayesian Nonparametric Statistics
… level. We introduce a method that identifies homogeneous groups in the data based on similarities among random effects parameters that are obtained when homogeneous groups are modeled using generalized linear mixed models. We achieve this by placing a Dirichlet Process prior on random effects …

Comparing Individualized Instruction in the Form of a Differentiated Jigsaw to Cooperative Learning in the Mathematics Classroom
… of students within an assignment. Even in homogeneous groups it is important to remember that competition and competence within the group can result in a threatening learning environment (Buchs & Butera, 2009). It is also important to promote dialogue within the groups of students, ensuring …

Development and validation of a classification system for child sexual abusers using the MMPI-2
… sexual abusers have typically been studied as a homogeneous group, comparing them with non-child sexual abusers. The present study was designed to examine the heterogeneity of child sexual abusers on a measure of psychopathology, the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the …

Monte Carlo validation of two genetic clustering algorithms
… type of statistical method designed to identify homogeneous groups within complex, multivariate data sets. In this study two newly developed genetic cluster analysis algorithms, GENCLUS and GENCLUS+, were validated by comparing their performance against that of three popular clustering techniques …

Evaluation des compétences cognitives, langagières et mnésiques des personnes trisomiques 21 ; pour une conception intégrative du retard mental
… many questions relating to the constitution of homogeneous groups and the evaluation of their developmental level (cognitive and linguistic), as well as the development of the various short-term memories. This work also presents our proposals for a solution to these three points.

Development of an inventory system for non-timber functions of forests in the frame of management inventories: the case of Greece
… with. A consecutive cluster analysis resulted to homogeneous groups of land units and forest stands, for which similar management prescriptions as well as silvicultural treatments could be drawn.

Trends in college student retention : identification of latent student classes with relation to retention statistics.
… retention. The ability to identify, and target, homogeneous groups of students will enable practitioners focused on college student success to target intervention strategies according to the characteristics of a single class, or profile, of students. This ability will make retention efforts more …

Clustering of variables around latent components: an application in consumer science
… around Latent Variables) for identifying groups of consumers in L-shape data. This kind of datastructure is very common in consumer studies where a panel of consumers is asked to assess the global liking of a certain number of products and then, preference scores are arranged in a two-way …

Effects of ability level compositions in cooperative learning settings
… on the type of students that compose these groups. The purpose of this study was to investigate the effects of homogeneous and heterogeneous ability created groups on individual student performance. Through the use of two problem solving activities, students were exposed to cooperative …

The effects of grouping fourth grade students into cooperative learning groups by learning patterns
… grade students working in cooperative learning groups. Students worked in three cooperative learning groups in order to determine whether grouping students heterogeneously into cooperative learning groups based on individual students' learning pattern would have a positive correlation with group …

Who, When, How (Not) to Imitate? The Role of Imitation in Collective Intelligence, and Its Implications on the Design of Socio-Technical Systems
… the group: 1. unbiased imitation works well in homogeneous groups as long as there is a minimum age for agents to be imitated; 2. imitation strategies based on models’ complete action history instead of their recent actions, although similar, can attain very different levels of group fitness; 3. …

The effects of lateral and vertical heterogeneity on focus group discussions for organizational and learner needs assessment
… Currently, the literature recommends that focus groups be composed of both laterally and vertically homogeneous group members to enhance trust among participants and facilitate positive group dynamics. Two research questions explored the relationship between heterogeneity and the quality of focus …

Basic functional and geometric inequalities for the fractional order operators on homogenous Lie groups
… and geometric inequalities on homo- geneous Lie groups. As for direct inequalities we obtain fractional Hardy, Sobolev, Hardy-Sobolev, Gagliardo-Nirenberg, Caffarelli-Kohn-Nirenberg, logarithmic inequal- ities, Hardy-Littlewood-Sobolev and Stein-Weiss inequalities on homogeneous Lie groups. Also, …

From Opinion Dynamics to Collective Action: How Identity-Based Tolerance Leads to Political Extremism
… structures the model generates. We show that homogeneous groups, often seen as indicators of polarization, could paradoxically be key to reducing organized extremism when dominated by moderates who can effectively mobilize collective action while marginalizing extremists.

Empirical analysis of rough set categorical clustering techniques based on rough purity and value set
Clustering a set of objects into homogeneous groups is a fundamental operation in data mining. Recently, attention has been put on categorical data clustering, where data objects are made up of non-numerical attributes. The implementation of several existing categorical clustering techniques is …
