Group Norms as Moderator in the Effect of Cross Group Friendship on Outgroup Attitude: a Study on Interreligious Group in Indonesia [PDF]

open access: yes, 2016
Past studies indicate that the effect of intergroup contact on outgroup attitude is not isolated to contextual factors. One of the contextual factors that has begun to be studied is group norm.

BAYESIAN GROUP TESTING WITH DILUTION EFFECTS [PDF]

open access: yesBiostatistics, 2021
SummaryA Bayesian framework for group testing under dilution effects has been developed, using latticebased models. This work has particular relevance given the pressing public health need to enhance testing capacity for COVID-19 and future pandemics, and the need for wide-scale and repeated testing for surveillance under constantly varying conditions.

Spinning Braid Group Representation and the Fractional Quantum Hall Effect [PDF]

open access: yes, 1992
The path integral approach to representing braid group is generalized for particles with spin. Introducing the notion of {\em charged} winding number in the super-plane, we represent the braid group generators as homotopically constrained Feynman kernels.

Group Personality Composition and Group Effectiveness

open access: yesSmall Group Research, 2005
This review examines relationships between group personality composition (GPC) and group effectiveness, focusing on four questions: (a) How have researchers operationalized GPC? (b) What criteria have been used as measures of group effectiveness? (c) Is GPC related to group effectiveness?

Group Testing with Consideration of the Dilution Effect

open access: yesMathematics, 2022
We propose a method of group testing by taking dilution effects into consideration. We estimate the dilution effect based on massively collected RT-PCR threshold cycle data and incorporate them into optimizing group tests. The new constraint helps find a

Study on the Compromise Effect Under the Influence of Normative Reference Group

open access: yesFrontiers in Psychology, 2022
The compromise effect is an important context effect, but its research is still insufficient under the influence of social factors and purchase tasks. This study explores the change of compromise effect in different group norm scenarios by constructing ...
