- Traffic sign identification using camera images from vehicles plays a critical role in autonomous driving and path planning. However, the front camera images can be distorted due to blurriness, lighting variations and vandalism which can lead to degradation of detection performances. As a solution, machine learning models must be trained with data from multiple domains, and collecting and labeling more data in each new domain is time consuming and expensive. In this work, we present an end-to-end framework to augment traffic sign training data using optimal reinforcement learning policies and a variety of Generative Adversarial Network (GAN) models, that can then be used to train traffic sign detector modules. Our automated augmenter enables learning from transformed nightime, poor lighting, and varying degrees of occlusions using the LISA Traffic Sign and BDD-Nexar dataset. The proposed method enables mapping training data from one domain to another, thereby improving traffic sign detection precision/recall from 0.70/0.66 to 0.83/0.71 for nighttime images.

- A highly significant element in politics and policies is the process of constructing, categorizing and imaging – such as categorizing citizens as target groups. In governing documents, distinctions are drawn to distinguish deserving and undeserving categories of citizens. This paper explores the construction of citizenship for people with dementia and the connection to underlying categories of rationales, by analyzing how this group has been categorized and imaged in policy documents. The study is based on a qualitative textual analysis of national policy documents in Sweden, covering nearly 40 years. It shows that the way people with dementia have been imaged has differed over time, where people living with dementia have been situated in various target groups and discourses. However, to a large extent, the underlying understanding has nevertheless remained persistent where the position of people with dementia has remained weak. It offers a taxonomy of categories of rationales and shows the interplay of rationales and target groups for certain social constructions. The study offers insights into the policy process related to policy change, and on citizenship as something transformative and interrelated that risks upholding democratic values that delimit disempowered groups, in this case people with dementia, to influence their citizenship.

Tidskriftsartikel (refereegranskat)abstract
- This article explores how policy narratives in national policy documents in Sweden inform associated politics on people with dementia. This is disentangled in terms of how people with dementia have been defined, what the problems and their imminent solutions have been, and if and how these have differed overtime. Based on a textual analysis of policy documents at national level in Sweden, covering nearly 40 years the study shows how divergent policy narratives shape the construction of citizens with dementia as policy target groups. This study shows the temporal character of people with dementia as a political problem, the implications of policy narratives on people with dementia as a citizen group, and policy narratives as something being crafted rather than shaped by fixed pre-existing "facts". Dementia, and further citizens living with dementia, does not have a once and for all stabilised meaning. Instead, the meanings behind the categories continue to evolve and to be crafted, which affects the construction of citizens living with dementia, the space in which to exercise their citizenship and further belonging to the society.

Social citizenship and people with dementia : Designing social care policies in Sweden
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- People with dementia are commonly in need of some form of social care from the social services in order to manage their everyday situations. However, social services are shaped by the construction of policy targets. The aim of this dissertation is to explore the social citizenship for people with dementia. Social citizenship for people with dementia is explored by studying how people with dementia, in policy documents, have been constructed as a target group and also by studying how policies are enacted in practice by care managers, in their work and in their meetings with people with dementia. This is illustrated by studying policy documents from national level which range over nearly 40 years and 19 interviews with care managers. It is shown that, if and when, people with dementia are visible in policy documents, they commonly have a negative construction based on their cognitive and communicative abilities, as a burden, disturbing and incapable. It is further investigated how street-level bureaucrats, in this case care managers, experience meeting with people with dementia when they apply for social services. It is shown that care-managers experience difficulties concerning this group comprised of the exchange of information between care managers and people with dementia, refusal of social services by the person, the influence of relatives and other professions as well as moral dilemmas, such as the relations between the person with dementia and their relatives. The study shows that care managers have little support from policies, e.g. legislation and guidelines, in how to handle these dilemmas, and must thus create their own local ways of handling these situations. Care managers are thus influential policy actors concerning the policy target group of people with dementia. The policy processes which this dissertation illustrates, affect the social citizenship of people with dementia. It is shown that they, to an extent, have difficulties in influencing their own everyday situation concerning social services. Finally, the policy processes, will affect their possibility to influence their social citizenship.

Tidskriftsartikel (refereegranskat)abstract
- This qualitative study, based on 19 interviews with care managers, explores the experiences of care-managers involved in assessing the need for social services for people with dementia. The study shows that social workers, as care managers, face several dilemmas in their practice concerning people with dementia, in relation to the exchange of information and in regards to conflicting interests between different actors involved in the assessment of the need for support for people with dementia. Strategies used to handle problematic situations that arise in their work are using other sources for information (e.g., relatives and actors from other professions), persuading, and pursuing creative forms of consent. However, the study shows that dilemmas and strategies used generate other, prominently moral, dilemmas for care managers in their practice, which relate to participation and self-determination by the person with dementia. The study shed light on the problematic situation for care managers in their work to coordinate information and further the new “realities“ that they encounter as well as on how to handle these new situations. This study suggests possible ways to improve the everyday work of care managers, as well as how policies concerning social work and people with dementia can be improved.
