Are defaults supportive of autonomy? An examination of nudges under the lens of Self-Determination Theory

Nudges, one of the rapidly growing law-making and public policy tools, are considered by their proponents to have a generally neutral effect on autonomy. Our study is the first to test nudges under the prism of Self-Determination Theory, a motivational theory which posits that autonomy is a basic psychological need. We focus on a specific type of nudge, defaults, and test it within the context of making a choice among a hypothetical set of insurance programs for post-graduate students. Results show that the experience of an Internal Perceived Locus of Causality (I-PLOC) is negatively affected by defaults when the number of options is low but there is no effect when it is high. In other words, people are less likely to view themselves as the origin of their choices when defaults are in place and when options are manageable. The experience of an I-PLOC has a positive effect on self-regulation and vitality, partially mediated by perceived competence. We suggest that since even mild manipulations show an undermining effect on autonomy, the so-called ‘libertarian paternalistic’ interventions should be evaluated on the basis of their effect on basic need satisfaction, self-regulation and vitality, all of which are associated with autonomy according to Self-Determination Theory

A self-determination theory account of self-authorship: Implications for law and public policy

Self-authorship has been established as the basis of an influential liberal principle of legislation and public policy. Being the author of one’s own life is a significant component of one’s own well-being, and therefore is better understood from the viewpoint of the person whose life it is. However, most philosophical accounts, including Raz’s conception of self-authorship, rely on general and abstract principles rather than specific, individual psychological properties of the person whose life it is. We elaborate on the principles of self-authorship on the basis of self-determination theory, an empirically based psychological theory that has been at the forefront of the study of autonomy and self-authorship for more than 45 years. Our account transcends distinctions between positive and negative freedom and attempts to pinpoint the exact properties of self-authorship within the psychological processes of intrinsic motivation and internalization. If a primary objective of public policy is to support self-authorship, then it should be devised on the basis of how intrinsic motivation and internalization can be properly supported. Self-determination theory identifies three basic psychological needs: autonomy, competence, and relatedness. The satisfaction of these needs is associated with the support and growth of intrinsic tendencies and the advancement of well-being. Through this analysis, we can properly evaluate the significance of rationality, basic goods, and the availability of options to self-authorship. Implications for law and policy are discussed with an emphasis on legal paternalism and what many theorists call “liberal perfectionism,” that is, the non-coercive support and promotion of the good life

Consistency and moral integrity: A self-determination theory perspective

If acting morally can be viewed as acting consistently with a moral principle or rule, then being a person with moral integrity can be viewed as consistently applying moral principles or rules across different types of situations. We advance a view of moral integrity that incorporates three distinct, but interrelated, types of moral consistency: cognitive, emotional and motivational moral consistency. Our approach is based on Self-Determination Theory, a motivational theory that can explain when a moral rule becomes the primary motive for behavior. We argue that moral integrity is achieved when a person acts on the basis of an internal moral system of principles, emotions and motives and provide an account of the way that it develops during a person’s interaction with the environment

OPEN THE DOOR AND LET ME IN: MOBILE PHONES AND THE DOCUMENTATION OF EVERYDAY LIFE

Museum documentation is usually understood as a systematic way of obtaining, creating and organising information and knowledge about objects and collections. However, this traditional perception of museum documentation may not provide the appropriate means to collect information and knowledge regarding everyday life and its cultural heritage, such as archaeological monuments in cityscapes. By being ‘exposed’ to daily life, archaeological monuments acquire dynamic, personal and everyday meanings, often too familiar and ephemeral to be grasped. To what extent can, then, museums access and document this everyday knowledge that shows the way people understand monuments in their daily life? Using as a context archaeological monuments in the city of Thessaloniki (Greece), this paper suggests that documenting ‘everyday meanings’ cannot be interpreted as the making of a complete record of them. It should be, rather, approached as the development of a ‘mobile gateway’, through which everyday knowledge can enter museums. The paper goes on to explore the potential of mobile phones, used by their owners, to capture and communicate everyday meanings of archaeological monuments. Mobile phones are considered ‘everyday technology’ and they are, already, used in disseminating museum knowledge to users. Drawing on fieldwork and qualitative investigation in Greece, the paper suggests that mobile phones could, also, be used as a means for museums to access and reveal everyday knowledge. In this case, museum documentation is seen not as an exhaustive systematisation of everyday knowledge, but an open communication channel, a ‘mobile gateway’, between people and museums through the use of mobile technology in everyday life. ‘No one, wise Kublai, knows better than you that the city must never be confused with the words that describe it. And yet between the one and the other there is a connection’. Italo Calvino (1997:61

Aggressive saliency-aware point cloud compression

The increasing demand for accurate representations of 3D scenes, combined with immersive technologies has led point clouds to extensive popularity. However, quality point clouds require a large amount of data and therefore the need for compression methods is imperative. In this paper, we present a novel, geometry-based, end-to-end compression scheme, that combines information on the geometrical features of the point cloud and the user's position, achieving remarkable results for aggressive compression schemes demanding very small bit rates. After separating visible and non-visible points, four saliency maps are calculated, utilizing the point cloud's geometry and distance from the user, the visibility information, and the user's focus point. A combination of these maps results in a final saliency map, indicating the overall significance of each point and therefore quantizing different regions with a different number of bits during the encoding process. The decoder reconstructs the point cloud making use of delta coordinates and solving a sparse linear system. Evaluation studies and comparisons with the geometry-based point cloud compression (G-PCC) algorithm by the Moving Picture Experts Group (MPEG), carried out for a variety of point clouds, demonstrate that the proposed method achieves significantly better results for small bit rates

Real time enhancement of operator's ergonomics in physical human - robot collaboration scenarios using a multi-stereo camera system

In collaborative tasks where humans work alongside machines, the robot's movements and behaviour can have a significant impact on the operator's safety, health, and comfort. To address this issue, we present a multi-stereo camera system that continuously monitors the operator's posture while they work with the robot. This system uses a novel distributed fusion approach to assess the operator's posture in real-time and to help avoid uncomfortable or unsafe positions. The system adjusts the robot's movements and informs the operator of any incorrect or potentially harmful postures, reducing the risk of accidents, strain, and musculoskeletal disorders. The analysis is personalized, taking into account the unique anthropometric characteristics of each operator, to ensure optimal ergonomics. The results of our experiments show that the proposed approach leads to improved human body postures and offers a promising solution for enhancing the ergonomics of operators in collaborative tasks

SHREC’20 Track:Retrieval of digital surfaces with similar geometric reliefs

International audienceThis paper presents the methods that have participated in the SHREC'20 contest on retrieval of surface patches with similar geometric reliefs and 1 the analysis of their performance over the benchmark created for this challenge. The goal of the context is to verify the possibility of retrieving 3D models only based on the reliefs that are present on their surface and to compare methods that are suitable for this task. This problem is related to many real world applications, such as the classification of cultural heritage goods or the analysis of different materials. To address this challenge, it is necessary to characterize the local "geometric pattern" information, possibly forgetting model size and bending. Seven groups participated in this contest and twenty runs were submitted for evaluation. The performances of the methods reveal that good results are achieved with a number of techniques that use different approaches
