Fairness in Machine Learning: A Survey.

Abstract: As Machine Learning technologies become increasingly used in contexts that affect citizens, companies as well as researchers need to be confident that their application of these methods will not have unexpected social implications, such as bias towards gender, ethnicity, and/or people with disabilities. There is significant literature on approaches to mitigate bias and promote fairness, yet the area is complex and hard to penetrate for newcomers to the domain. This article seeks to provide an overview of the different schools of thought and approaches to mitigating (social) biases and increase fairness in the Machine Learning literature. It organises approaches into the widely accepted framework of pre-processing, in-processing, and post-processing methods, subcategorizing into a further 11 method areas. Although much of the literature emphasizes binary classification, a discussion of fairness in regression, recommender systems, unsupervised learning, and natural language processing is also provided along with a selection of currently available open source libraries. The article concludes by summarising open challenges articulated as four dilemmas for fairness research.

Toward a More Comprehensive Understanding of Peer Maltreatment: Studies of Relational Victimization

Abstract: Although many past studies of peer maltreatment have fo- cused on physical victimiza- tion, the importance of an empirical focus on relational victimization has only recently been recognized. In relational victimization, the perpetrator attempts to harm the target through the manipulation of re- lationships, threat of damage to them, or both. We review what is currently known about rela- tional victimization with three issues in mind: (a) developmen- tal changes in the manifesta- tion of relational victimization, (b) gender differences in the likelihood of being victimized, and (c) evidence that relational victimization is harmful.

Causal Relationships in Creative Problem Solving: Comparing Facilitation Interventions for Ideation

Abstract: Organizations must be creative continuously to survive and thrive in today's highly competitive, rapidly changing environment. A century of creativity research has produced several descriptive models creativity, and hundreds of prescriptions for interventions that demonstrably improve creativity. This paper presents the cognitive network model (CNM) as a causal model of the cognitive mechanisms that give rise to creative solutions in the human mind. The model may explain why creativity prescriptions work as they do. The model may also provide a basis for deriving new techniques to further enhance creativity. The paper tests the model in an experiment where 61 four-person groups used either free-brainstorming or one of three variations on directed-brainstorming to generate solutions for one of two unstructured tasks. In both tasks, people using directed-brainstorming produced more solutions with high creativity ratings, produced solutions with higher average creativity ratings, and produced higher concentrations of creative solutions than did people using free-brainstorming. Significant differences in creativity were also found among the three variations on directed-brainstorming. The findings were consistent with the CNM.
