    Sjuksköterskors erfarenheter att vårda patienter med blodsmitta: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Nurses care for patients with hepatitis B, hepatitis C and HIV daily. The risk of being exposed to infection can create anxiety and fear, which can influence nurses to provide good care on equal terms. Experience in caring for patients with blood contamination is therefore important for the professional development of the subject. Purpose: The purpose is to elucidate nurses' experiences of caring for patients with blood contamination. Method: A literature review with quantitative and qualitative articles was carried out. Result: Four themes emerged in the result. Nurse's knowledge and ignorance, Lack of resources affects nursing, Risks create fear and worry as well as approach and holistic view. Conclusion: Nurses in developing countries are at higher risk of being exposed to infection and have less opportunity to live up to the profession because financial and material resources are lacking. Knowledge and resources are required to enable good care.

    Abstract [en]

    In an article published in Nature: Human Behavior, Nunez et al. (2019) asks What happened to cognitive science? The authors review bibliometric and socio-institutional aspects of the field and argues that the transition from a multi-disciplinary program to a mature inter-disciplinary coherent field has failed. Looking at the Swedish environment, we can nothing but agree. Many of us identifying ourselves as researchers in cognitive science are working at departments primarily focused at other disciplines, teaching within other objects and publishing in journals and conferences adjacent to the field. The diversity of cognitive science is also present in the number of directions that has has evolved over the years. The embodied approaches that many of us align with are not evolving towards a coherent view, but is today found under numerous labels such as situated cognition, distributed cognition, extended cognition, and enactive cognition. The so called 4E perspectives on the field have now ventured beyond the four, and is today more often referred to as the multi-E framework.

    While we agree with Nunez et al. that we remain a multi-disciplinary, multi-perspective, and multi-method group of researchers who may share an interest for the science of the mind, rather than a coherent approach or perspective, we disagree that this entails a failure for the enterprise of cognitive science. We dare to say that the Sweish Cognitive Science Society has embraced the multi-perspectives idea by adopting an inclusive approach in the selection of research and methods presented at our conferences. We hope that SweCog will remain a forum for inclusive discussions, working against discipline conformism and isolation, in a time where both public and scientific debate is increasingly shattered.

    OCD and Empathy Games: Using empathy games to inform the public about ODC2019Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This research focuses on obsessive-compulsive disorder (OCD) and how games focused on making the player feel empathy (empathy games) can increase the public’s general knowledge of the disorder. The disorder is currently commonly misunderstood and is not always taken seriously, something that potentially could hurt those with OCD. The stigma surrounding OCD sometimes makes people avoid getting the help they need, making them suffer in silence. The objective of the research was to define several game design principles that suggests what a developer should focus on when making an empathy game about OCD with the purpose to inform the general public. This was done by analyzing several scientific articles discussing either OCD or empathy games, and concluding the most important parts from them into game design principles. Four game design principles were found; target audience, reality, clarity, and includation. These have not been tested in a practical setting, but can possibly serve as guidelines when making an empathy game focusing on OCD.

    Abstract [en]

    Background: Diabetes mellitus type 2 is a disease where the number of individuals with the condition is constantly increasing. Adolescents are affected by the disease as a result of being overweight with featuring elements of heredity and ethnicity. Reasons for diabetes type 2 are associated with risk factors regarding unhealthy living habits.Aim: The purpose is to describe adolescents’ experiences of living with diabetes type 2.Method: The method is a qualitative literature review including 7 scientific articles.Results: Adolescents with diabetes type 2 find it difficult to adapt to new habits after the onset of illness. Lifestyle changes are implemented in the form of changed diet- and exercise habits, which are affected by various obstacles or opportunities. The adolescents experience a lack of understanding from health care professionals and wish for more support. Adolescents experience fear and concern about telling their friends about the illness. The need for support from both friends and family is significant.Conclusion: Adolescents with diabetes type 2 struggle to maintain a healthy lifestyle that is required to keep the illness under control. The fear of being different reflects the difficulties the adolescents’ experience. Adolescents need support and encouragement to maintain healthy habits as well as their well-being.

    Hur barn upplever den nya livssituationen till följd av traumatiska händelser: En litteraturöversikt med kvalitativ ansats2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Nursing is the nurse's specific competence that includes the child-centered care work to meet and manage the child's unique needs and alleviate the child's suffering. Purpose: The purpose was to describe how children experience the new life situation as a result of traumatic events. Method: This essay is a literature review with a qualitative approach, based on ten scientific articles that were analyzed according to Friberg's method. Results: In a traumatic event, the child is scared and may feel different and alone. This can affect the child for a long time to come when the child is reminded and relives the traumatic event. Conclusion: The traumatic event creates a new life situation that affects the child at the event and far into the future if the child’s needs are not met and handled during the hospitalization.

    The Subjective Experience of Anxiety and Its Relation to Performance2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    There have been many attempts to explain the experience of anxiety during different types of performance situations. There are several different views on the brain mechanisms of anxiety. The traditional view has its focus on amygdala but recent research questions this view. In this essay the focus is on how two recent theories, namely the two-system model (LeDoux & Pine, 2016) and the attentional control theory (Eysenck, Derakshan, Santos & Calvo, 2007) has changed the theoretical landscape of the brain mechanisms behind the experience of anxiety. The two-system framework model claim that the subjective experience of anxiety uses the same cortical circuits as executive functions involved in attention and working memory. Whereas the attentional control theory argues, that due to the limited attentional capacity, increasing the subjective experience of anxiety would result in less capacity for executive functions involved in working memory and attention resulting in impaired performance. This review shows that research on the relationship between the subjective experience of anxiety and performance is inconsistent and researchers possess different views on what gives rise to the experience. Some data indicate that the amygdala is crucial for the subjective experience of anxiety while other data suggest that other cortical circuits have a much more prominent role. If the cortical circuits are strongly involved in the subjective experience of anxiety, this would be strong support for the attentional control theory and the two-system framework model.

    Conscious by Default: The Role of the Default Mode Network in Internal Awareness2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Abstract

    In the 1990s researchers discovered task-deactivated regions in the human brain. Together, these areas make up the default mode network (DMN). It was originally proposed to act as a balancing mechanism between different brain systems, explaining the deactivations, but is now mostly studied with regards to internal awareness, such as daydreaming and mental imagery. The purpose of this thesis is to present a summary of DMN research, focusing on the network’s suggested role in internal awareness. This will be done by reviewing a wide variety of research that either explicitly or indirectly correlate default mode network features with aspects of consciousness and internal awareness. The subjective experience of being conscious have been a source of argument primarily among philosophers, but the qualities we feel are intimately linked to cognitive functions that are supported by the regions found in the DMN. Cognitive neuroscience may therefore be able to contribute to the concept of internal awareness and consciousness.

    A Framework for GDPR Compliance for Small- and Medium-Sized Enterprises2019In: European Journal for Security Research, ISSN 2365-0931, E-ISSN 2365-1695, Vol. 4, no 2, p. 243-264Article in journal (Refereed)
    Abstract [en]

    The EU’s General Data Protection (GDPR) is an EU regulation that affects everyone in the EU and all organisations outside the EU that wants to do business with the EU. GDPR introduces tougher requirements for processing personal data, which may be difficult for many small- and medium-sized enterprises (SMEs) to follow without major adjustments. This work uses design science to develop a framework for SMEs to adapt to GDPR. The framework was empirically evaluated in three different types of organisations, resulting of GDPR compliance according to their Data Protection Officers. It was also theoretical evaluated against scientific literature including the identified implications of GDPR. In this paper the framework is presented, from initial analysis and design to implementation and future work, with advice on how to work with each part to achieve compliance. The paper also highlights some of the most important changes in GDPR compared to its predecessor, Directive 95/46/EC of the European Parliament and of the Council of 24 October 1995 on the protection of individuals with regard to the processing of personal data and on the free movement of such data (DIR95).

    Rounding based continuous data discretization for statistical disclosure control2019In: Journal of Ambient Intelligence and Humanized Computing, ISSN 1868-5137, E-ISSN 1868-5145, p. 1-19Article in journal (Refereed)
    Abstract [en]

    “Rounding” can be understood as a way to coarsen continuous data. That is, low level and infrequent values are replaced by high-level and more frequent representative values. This concept is explored as a method for data privacy with techniques like rounding, microaggregation, and generalisation. This concept is explored as a method for data privacy in statistical disclosure control literature with perturbative techniques like rounding, microaggregation and non-perturbative methods like generalisation. Even though “rounding” is well known as a numerical data protection method, it has not been studied in depth or evaluated empirically to the best of our knowledge. This work is motivated by three objectives, (1) to study the alternative methods of obtaining the rounding values to represent a given continuous variable, (2) to empirically evaluate rounding as a data protection technique based on information loss (IL) and disclosure risk (DR), and (3) to analyse the impact of data rounding on machine learning based models. Here, in order to obtain the rounding values we consider discretization methods introduced in the unsupervised machine learning literature along with microaggregation and re-sampling based approaches. The results indicate that microaggregation based techniques are preferred over unsupervised discretization methods due to their fair trade-off between IL and DR.

    Germinating good behaviors: A game prototype to test players' incentive of choice2019Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    In this paper, we propose and develop a model for a prototype research tool based on a social dilemma game which use is widely spread in social psychology and experimental economics, the Public Goods Game. This tool generates from the necessity to expand the accessibility and versatility of this popular game as well as reach for newer audiences that might be otherwise deterred by the traditional Public Goods Game. Also, using this tool, we perform an experiment to try to find a possible preference towards either punishment or reward in the current population and find a possible correlation between said preference and three different cultural spheres (geographical, generational and gender).

    Att återgå till vardagen: En kvalitativ litteraturöversikt om strokedrabbade patienters upplevelser2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Stroke is one of the most common diseases in Sweden and the primary reason why adults get disabilities. Stroke means a great conversion for the patient which leads to a changed everyday life. There are many factors that affects the patients’ quality of life. Rehabilitation and support from the interdisciplinary team and family are important for efficiency of the recovery. Aim: The aim of this study was to describe patients’ experiences of everyday life after stroke. Method: The method was a literature review based on qualitative studies and were analyzed with qualitative content analysis. Results: The analyses resulted in three main catagories; changed living, changed identity and needs of help forward. Patients experienced a changed living because of the circumstances their stroke gave them. Their home and closest family were two main factors for the patients to feel safe. Because of the stroke patients received a new body that meant both physical and psychological changes. The patients got to learn their new body which was experienced as demanding. Patients needed tools to be able to handle their new everyday life and changed body, which they received from the interdisciplinary team. Conclusion: Patients experienced that their quality of life was affected negativly because of the life adjusment after the stroke. What gave the patients meaning and connection became more clear after the stroke, to revert the ”old me” were highly priotitized. The social and profesional support was important for the rehabilitation. Together they created a saftey net for the patient and enabled a meaningful future.

    A zebrafish model system for drug screening in diabetes2019Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    GWAS (Genome wide association studies) have aided in the discovery of various novel variants associated with diabetes. However, a detailed study is required to uncover the role of these genes and to determine how their dysfunction affects pathophysiology. Previous work in the lab has been successful in establishing zebrafish as an efficient model to characterise the effects of these candidate genes. Consequently, efforts have been also made to establish zebrafish as an efficient model system for drug screening as well. The current POP (Proof of principle) study aims to find whether treatment with tolbutamide drug in zebrafish carrying MODY (Maturity onset diabetes of the young) mutations has the similar effects in humans. The study employed zebrafish carrying five (gck, hnf1a, hnf1ba, hnf1bb, pdx1) CRISPR induced MODY orthologues. The zebrafish larvae were supplemented with tolbutamide drug from 5dpf till 10dpf (day post fertilisation). At 10dpf, larvae were screened for various glycaemic traits, whole body glucose and lipids as well body size. CRISPR-CAS9- induced mutations were quantified using paired end sequencing. The results showed that treatment with tolbutamide had a significant effect on the hyperglycaemic outcome induced by hnf1bb, hnf1a, and pdx1 mutations which was in line with the known effects of the drug in humans. In conclusion, the POP study proved to be successful in leveraging zebrafish as an efficient model system for, in vivo characterisation of drugs and can likely help to identify novel targets for therapeutic interventions.

    Sjuksköterskors och barnmorskors upplevelser av vårdmöten med endometriosdrabbade kvinnor: En enkätstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Endometriosis is a disease in which the uterine mucosa grows elsewhere than in the uterus. Endometriosis can cause severe pain and great suffering for the affected woman. Research shows that endometriosis-afflicted women experience inadequate care and a lack of knowledge from the health care system. Purpose: The purpose was to investigate nurses’ and midwives’ experiences of the healthcare encounters with endometriosis-affected women. Method: Quantitative method with a qualitative elements and a descriptive approach via an empirical study. Results: Most study participants experience shortcomings in their knowledge of endometriosis and want more knowledge to be able to respond to and help endometriosis-affected women. Some of the study participants do not experience deficiencies to the same extent, but still want more knowledge about the gynecological disease endometriosis. There are factors that affect communication in healthcare encounters. Endometriosis-affected women are perceived to be difficult to respond to and help. Conclusion: The knowledge and awareness of endometriosis needs to be deepened in all the nurses in the study. In-depth knowledge can mean that nurses feel more secure in healthcare encounters, which can result in better nursing care for endometriosis-affected women.

    Prevention of Input Validation Vulnerabilities on the Client-Side: A Comparison Between Validating in AngularJS and React Applications2019Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this research was to test the JavaScript library React and framework AngularJS against each other in regard of the response time of the validation and validation robustness. The experiments in this work were performed to support developers in their decision making regarding which library or framework to use. There are many other aspects to consider when choosing which library or framework to develop in other than the security and response time related aspects mentioned in this work, but this work can, amongst other information, give yet another viewpoint to the developers. The results showed that there is no difference amongst them security wise, but that it was somewhat faster to validate in a React application than in an AngularJS application.

    Design of a modular delivery vehicle for cities2019Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report describes the conceptual design and development of a virtual prototype of a sustainable delivery vehicle for cities in the European Union. The project was carried out as a multidisciplinary project where one product design engineering student and one mechanical engineering student participated. The project’s design process was based on “The Mechanical Design Process” methodology by Ullman and secondary it was influenced by the product process of Ulrich & Eppinger.

    The initial phase of the project aimed to define the problem area and to set the requirements for the vehicle. This phase included: study of the problem, study of stakeholders, market research and an ergonomics study. When the requirements were set and clarified, the concept generation phase followed. The generated design concepts were then assessed according to the fulfilment of set requirements. One final concept was chosen for further development in the following product generation phase. In this phase, the vehicle was designed using virtual tools, and the design was developed and evaluated in further detail. The final concept is considered to fulfil most requirements, although there are some requirements that require further investigation and development.

    VIRTUAL PRIVATE NETWORKS: An Analysis of the Performance in State-of-the-Art Virtual Private Network solutions in Unreliable Network Conditions2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This study aimed to identify the differences between state-of-the-art VPN solutions on different operating systems. It was done because a novel VPN protocol is in the early stages of release and a comparison of it, to other current VPN solutions is interesting. It is interesting because current VPN solutions are well established and have existed for a while and the new protocol stirs the pot in the VPN field. Therefore a contemporary comparison between them could aid system administrators when choosing which VPN to implement. To choose the right VPN solution for the occasion could increase performance for the users and save costs for organizations who wish to deploy VPNs. With the remote workforce increasing issues of network reliability also increases, due to wireless connections and networks beyond the control of companies. This demands an answer to the question how do VPN solutions differ in performance with stable and unstable networks?

    This work attempted to answer this question. This study is generally concerning VPN performance but mainly how the specific solutions perform under unreliable network conditions.It was achieved by researching past comparisons of VPN solutions to identify what metrics to analyze and which VPN solutions have been recommended. Then a test bed was created in a lab network to control the network when testing, so the different VPN implementations and operating systems have the same premise. To establish baseline results, performance testing was done on the network without VPNs, then the VPNs were tested under reliable network conditions and then with unreliable network conditions. The results of that were compared and analyzed.

    The results show a difference in the performance of the different VPNs, also there is a difference on what operating system is used and there are also differences between the VPNs with the unreliability aspects switched on. The novel VPN protocol looks promising as it has overall good results, but it is not conclusive as the current VPN solutions can be configured based on what operating system and settings are chosen. With this set-up, VPNs on Linux performed much better under unreliable network conditions when compared to setups using other operating systems.

    The outcome of this work is that there is a possibility that the novel VPN protocol is performing better and that certain combinations of VPN implementation and OS are better performing than others when using the default configuration. This works also pointed out how to improve the testing and what aspects to consider when comparing VPN implementations.

    Anti-forensik mot minnesforensik: En litteraturstudie om anti-forensiska metoder mot minnesdumpning och minnesanalys2019Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    IT forensics face many difficulties in their work of obtaining and analyzing data. Criminals are using more and more anti-forensic methods to hide evidence that can be used against them. One common anti-forensic method is encryption. In order for IT forensics to access the encrypted information, the encryption key can be found in the memory of the computer. This makes the computer's memory valuable to retrieved and analyze. However, there are several anti-forensic methods that a criminal can use to prevent the memory from being retrieved or analyzed. This study performs a systematic literature study to identify the current anti-forensic methods against memory analysis and memory dumping on Windows system. Several methods are addressed where, among other things, the operating system is modified or built-in security functions on the CPU are used to prevent information being retrieved or analyzed from memory.

    Towards facilitating BI adoption in small and medium sized manufacturing companies2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This work concerns how to support Small and Medium sized Manufacturing Enterprises(SMMEs) with their Business Intelligence (BI) adoption, with the long term aim of supporting them in making better use of their BI investments and becoming (more)data-driven in their decision-making processes. Current BI research focuses primarily on larger enterprises, despite the fact that the majority of businesses are small or mediumsized. Therefore, this research focuses on the body of knowledge concerning how SMMEs can be more intelligent about their business, and better adopt BI to improve decision-making. Accordingly, the overall research aim is to create an artefact that can support SMMEs to facilitate BI adoption. An understanding of the current situation of BI adoption within SMMEs needs to be attained to achieve this, which is the focus for the first research question: What is the current state-of-practice in relation to BI adoption in SMMEs? The research question adds to current knowledge on how SMMEs are taking advantage of BI and highlights which functions within companies are currently supported by BI. Research question two identifies the main challenges that SMMEs are facing in this context: What are the main challenges for BI adoption in SMMEs? This question adds to knowledge regarding some of the barriers and hindrances SMMEs face in BI adoption. Finally, the third research question addresses how SMMEs can address the challenges in successfully adopting BI: How can the main challenges be addressed? The research question is answered by providing descriptions of work in four participating companies addressing different types of problems. Many of the challenges from literature (and from empirical data from the participating companies) regarding BI adoption are met. The outcome adds to the literature a hands-on approach for companies to address chosen problems in their settings, and addressing many of the factors previously found in the BI adoption literature. An action design research (ADR) method is used to fulfill the overall research aim. The ADR method is used to guide the development of a framework artefact based on previousliterature, and on empirical findings from working with participating companies. Theoretical background was obtained through a literature review of BI adoption and usage. Empirical material was gathered both through interviews and by reviewing documents from the companies. The work that was done in participating companies was supported by previous literature in several ways: through the use of an elicitation activity, through the core concepts of BI, and by focusing on categories presented in a BI maturity model. The principal contribution of the research is in the form of a framework: the Business Intelligence Facilitation Framework (BIFF), which includes four phases. All phases contain activities that support companies in addressing BI adoption challenges from the literature and empirical data, in order to achieve the overall research aim. This research contributes both to research and practice. From a research point of view, the framework provides a way to address many of the factors previously identified in literature that need to be in place to increase the likelihood of successful BI adoption. From a practice perspective, the framework supports practitioners offering guidance in how to improve their BI adoption, providing activities for them to take, and guidance in how to carry out the activities.

    Samband mellan skärmtid och psykisk ohälsa: framtidens folkhälsoutmaning?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion Användningen av digitala skärmar ökar drastiskt världen över. Parallellt ökar även förekomsten av psykisk ohälsa, vilket numera är ett globalt växande folkhälsoproblem. Psykisk ohälsa är den tredje främsta orsaken till den totala sjukdomsbördan i Världen.

    Syfte Syftet med studien var att belysa samband mellan ST och psykisk ohälsa. Metod Studien använde sig av en systematisk litteraturöversikt som studiedesign. 21 vetenskapliga artiklar inkluderades och analysen genomfördes enligt en systematisk textkondensering.

    Resultat Resultatet tyder på att det finns ett samband mellan skärmtid och psykisk ohälsa. Resultatet tyder även på att det verkar föreligga skillnader mellan hur skärmtid påverkar män och kvinnors psykiska hälsa. Fyra teman identifierades: depression, ångest, stress och övriga psykiska besvär.

    Slutsats Denna studie visar på att det verkar finnas ett samband mellan skärmtid och psykisk ohälsa. För att i framtiden skapa rekommendationer och riktlinjer kring skärmanvändade, krävs mer forskning kring orsakssamband, samt för att få en djupare förståelse för mekanismerna bakom skärmtidens effekt på människors psykiska hälsa.

    Reverse Hierarchy Theory and the Role of Kinematic Information in Semantic Level Processing and Intention Perception2019Conference paper (Refereed)
    Abstract [en]

    In many ways, human cognition is importantly predictive (e.g., Clark, 2015). A critical source of information that humans use to anticipate the future actions of other humans and to perceive intentions is bodily movement (e.g., Ansuini et al., 2014; Becchio et al., 2018; Koul et al., 2019; Sciutti et al., 2015). This ability extends to perceiving the intentions of other humans based on past and current actions. The purpose of this abstract is to address the issue of anticipation according to levels of processing in visual perception and experimental results that demonstrate high-level semantic processing in the visual perception of various biological motion displays. These research results (Hemeren & Thill, 2011; Hemeren et al., 2018; Hemeren et al., 2016) show that social aspects and future movement patterns can be predicted from fairly simple kinematic patterns in biological motion sequences, which demonstrates the different environmental (gravity and perspective) and bodily constraints that contribute to understanding our social and movement-based interactions with others. Understanding how humans perceive anticipation and intention amongst one another should help us create artificial systems that also can perceive human anticipation and intention.

    Review of simulation-based life cycle assessment in manufacturing industry2019In: Production & Manufacturing Research, ISSN 2169-3277, Vol. 7, no 1, p. 490-502Article in journal (Refereed)
    Abstract [en]

    The manufacturing industry has a duty to minimize its environmental impact, and an increasing body of legislation mandates environmental impact evaluations from a life cycle perspective to prevent burden shift. The manufacturing industry is increasing its use of computer-based simulations to optimize production processes. In recent years, several published studies have combined simulations with life cycle assessments (LCAs) to evaluate and minimize the environmental impact of production activities. Still, current knowledge of simulations conducted for LCAs is rather disjointed. This paper accordingly reviews the literature covering simulation-based LCAs of production processes. The results of the review and cross-comparison of papers are structured in terms of seven elements in line with the ISO standard definition of LCA and report the strengths and limitations of the reviewed studies. © 2019, © 2019 The Author(s).

    Random dictatorship for privacy-preserving social choice2019In: International Journal of Information Security, ISSN 1615-5262, E-ISSN 1615-5270, p. 1-9Article in journal (Refereed)
    Abstract [en]

    Social choice provides methods for collective decisions. They include methods for voting and for aggregating rankings. These methods are used in multiagent systems for similar purposes when decisions are to be made by agents. Votes and rankings are sensitive information. Because of that, privacy mechanisms are needed to avoid the disclosure of sensitive information. Cryptographic techniques can be applied in centralized environments to avoid the disclosure of sensitive information. A trusted third party can then compute the outcome. In distributed environments, we can use a secure multiparty computation approach for implementing a collective decision method. Other privacy models exist. Differential privacy and k-anonymity are two of them. They provide privacy guarantees that are complementary to multiparty computation approaches, and solutions that can be combined with the cryptographic ones, thus providing additional privacy guarantees, e.g., a differentially private multiparty computation model. In this paper, we propose the use of probabilistic social choice methods to achieve differential privacy. We use the method called random dictatorship and prove that under some circumstances differential privacy is satisfied and propose a variation that is always compliant with this privacy model. Our approach can be implemented using a centralized approach and also a decentralized approach. We briefly discuss these implementations.

    ADHD och risken för kriminellt beteende senare i livet: en litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction

    ADHD is a neuropsychiatric disorder belonging to the spectrum of neuro-cognitive functional that increases the risk of getting into crime later in life. Individuals with the disorder may be incapable of controlling their impulses, which means that the individuals with the problem is not capable of evaluating consequences of his/her behavior. ADHD is also something that increases the risk of becoming a victim of abuse and destructive behavior

    Method

    A literature review with 10 knowledge-based articles was used in the study for the basis of the result. The articles were reviewed and processed to obtain as strong a reliability as possible. The database launched was Pubmed which gave many hits according to the keywords but the included studies were carefully selected based on the delimitation by the aim of the study and the relevance of the chosen area.

    Purpose

    The aim of the work was to explore the connection between the diagnosis of ADHD and subsequent risk of criminal behavior.

    Results

    Adolescents diagnosed with ADHD showed a clear increased risk of developing addiction problems. The ADHD symptoms had often become more difficult during childhood or adolescence and persons with ADHD were also more probably imprisoned as adults. The most common drugs that were used by the individuals with ADHD and had developed addiction were stimulants such as alcohol and benzodiazepines. The adolescents with ADHD and developed addiction had performed significantly poorer in tests and in school and showed poorer results than those who had not diagnosed ADHD

    Discussion Clear results were common to many of the selected articles as there was a clear correlation between ADHD and risk of becoming a victim of abuse and subsequent criminal behavior. Several of the articles mention that young people with the diagnosis of ADHD have obvious problems in gaining education and that this in turn leads to exclusion and poor social adaptation
