1.	Andersson, Christian H., et al. (författare) Mathematical understanding of training data and AI : a lesson plan for critical thinking and ethical perspectives 2024 Ingår i: Proceedings / Actes CIEAEM 74. - Palermo, Italy. ; , s. 681-685 Konferensbidrag (refereegranskat)abstract AI and machine learning are increasingly being applied to solve complex societal issues. One approach is to train algorithms on training data that describes human behavior. This is not without potential problems though. For example, historical human behavior may contain biases, and then algorithms may reproduce social injustices. This workshop contained lesson elements from a study where pre-service mathematics teachers conducted lessons to first conceptually teach how mathematical modelling based on machine learning works, and then to broaden the scope to consider critical thinking in relation to ethics and democratic values. The participants were invited to test and discuss the lesson elements.
2.	Andersson, Malou, 1973- (författare) Grov fridskränkning och grov kvinnofridskränkning : Fridskränkningsbrotten som rättslig konstruktion 2016 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Over the last decades men’s physical and psychological violence against women in intimate relationships (domestic violence) has become a central issue in Swedish politics. Men’s physical and psychological violence against women is generally be understood as including physical, sexual and psychological violence (e.g rape, battery, sexual abuse or insults) that occurs within the family, whether or not the perpetrator shares or has shared the same residence with the woman. Law reforms have been carried through with the objective of enhancing criminal legal protection for women. In 1999, a new law came into force within the framework of chapter 4 of the Penal Code which includes any member of the family with the objective to treat acts that are already criminal from a different perspective if they are committed within a pattern of systematic physical and psychological violence.This doctoral thesis examines the concept of domestic violence and the criminal act in Chapter 4, section 4 a of the Swedish Penal Code which prescribes liability for violation of integrity offences. According to the first paragraph, a person who commits criminal acts as defined in Chapters 3, 4, 6 or 12 or of the Swedish Penal Code (e.g. rape, battery, sexual abuse or insults) or violation of a restraining order against a person with whom they have or have previously had, a close relationship will be sentenced for gross violation of integrity to imprisonment for at least nine months and at most six years if each of the acts were part of a repeated violation of the person’s integrity and the acts were liable to severely damage the person’s self-esteem. The second paragraph states if the acts were committed by a man against a woman to whom he is, or has been married or with whom he is, or has been cohabiting under circumstances comparable to marriage. He will instead be sentenced for a gross violation of a woman’s integrity to the same punishment. The objective of introducing a violation of integrity offence was to enable criminal proceedings to take in to account the abused person’s entire situation when he or she has been subjected to a series of albeit punishable but often individually relatively minor acts and to bring about an upgrading of the penal value of such acts. The main purpose of this thesis is to examine when and under which circumstances a person can be held responsible for gross violation of integrity or gross violation of a woman’s integrity. The analysis aims at the construction of the law, but also to examine the legal and social consequences and the interpretation and application of the law.

Phys.. - : AIP Publishing. - 0021-9606. ; 124 Tidskriftsartikel (refereegranskat)abstract Using nozzle beams of He, Ne, and Ar, we have measured diffractive selective adsorption resonances from a Cu(110) surface kept at 20 K. Bound state energies of the atom-surface potentials have been determined from plots of the measured resonance energies versus incident angle and their fits to calculated kinematical dispersion relations. For 3He and 4He we have found a unique level assignment that is compatible with a single gas-surface potential curve with a well depth of 6.05 meV of the He–Cu(110) potential. This value is about 10% larger than the prediction of 5.55 meV from the current physisorption theory. The Ne and Ar data reveal a large number of closely spaced levels with level separations and estimated van der Waals coefficients that are compatible with available theoretical data.

(författare) Human Pluripotent Stem Cell-Derived Hepatocytes Show Higher Transcriptional Correlation with Adult Liver Tissue than with Fetal Liver Tissue 2020 Ingår i: ACS Omega. - : American Chemical Society (ACS). - 2470-1343. ; 5:10, s. 4816-4827 Tidskriftsartikel (refereegranskat)abstract Human pluripotent stem cell-derived hepatocytes (hPSC-HEP) display many properties of mature hepatocytes, including expression of important genes of the drug metabolizing machinery, glycogen storage, and production of multiple serum proteins. To this date, hPSC-HEP do not, however, fully recapitulate the complete functionality of in vivo mature hepatocytes. In this study, we applied versatile bioinformatic algorithms, including functional annotation and pathway enrichment analyses, transcription factor binding-site enrichment, and similarity and correlation analyses, to datasets collected from different stages during hPSC-HEP differentiation and compared these to developmental stages and tissues from fetal and adult human liver. Our results demonstrate a high level of similarity between the in vitro differentiation of hPSC-HEP and in vivo hepatogenesis. Importantly, the transcriptional correlation of hPSC-HEP with adult liver (AL) tissues was higher than with fetal liver (FL) tissues (0.83 and 0.70, respectively). Functional data revealed mature features of hPSC-HEP including cytochrome P450 enzymes activities and albumin secretion. Moreover, hPSC-HEP showed expression of many genes involved in drug absorption, distribution, metabolism, and excretion. Despite the high similarities observed, we identified differences of specific pathways and regulatory players by analyzing the gene expression between hPSC-HEP and AL. These findings will aid future intervention and improvement of in vitro hepatocyte differentiation protocol in order to generate hepatocytes displaying the complete functionality of mature hepatocytes. Finally, on the transcriptional level, our results show stronger correlation and higher similarity of hPSC-HEP to AL than to FL. In addition, potential targets for further functional improvement of hPSC-HEP were also identified.

The trend hasin recent years been reversed because society has realized the many benefits of wetlandfunctions, such as for nutrient retention and flood control. In this study we inventoried 75 wetlands in Uppland and Halland for insects and spiders with Malaise traps, pitfall traps andsuction sampling. Most included wetlands are constructed, because the main purpose was toexamine if these wetlands also can be good for arthropod diversity, but we also included somemore natural wetlands as comparison. In total, we identified more than 25,000 individualsof more than 900 species of Coleoptera, Araneae, Diptera and Heteroptera. We found onenew species for Sweden, Hilara manicata Meigen 1822, and 37 new regional records. Alarge number of species found are considered threatened or else rare. Some wetlands closeto Mälaren were particularly interesting, with three species (Hypsosinga heri (Hahn 1831),Rhaphium antennatum (Charlier 1835) and Bagous robustus Brisout de Barneville 1863)that have no records nearby during recent times. These and other species found in the studyshow that constructed wetlands can provide good habitats for arthropod biodiversity andrare species, particularly if wetland shores are grazed and trampled by cattle.

(författare) Personality Change following Internet-Based Cognitive Behavior Therapy for Severe Health Anxiety 2014 Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 9:12, s. e113871- Tidskriftsartikel (refereegranskat)abstract Personality traits have traditionally been viewed as stable, but recent studies suggest that they could be affected through psychological treatment. Internet-based cognitive behavior therapy (ICBT) for severe health anxiety (DSM-IV hypochondriasis) has been shown to be effective in reducing health anxiety, but its effect on measures of personality traits has not been investigated. The main aim of this study was to investigate the impact of ICBT on personality traits in the three broad dimensions -neuroticism, extraversion and aggression. We hypothesized that participants in ICBT would reduce their level of neuroticism compared to controls that did not receive the active treatment. No specific predictions were made regarding extraversion and aggression. Data from a randomized controlled trial were used in which participants were allocated to 12 weeks of ICBT (n=40) or to a basic attention control condition (n=41). Personality traits were assessed with the Swedish Universities Scales of Personality and the primary outcome of health anxiety was the Health Anxiety Inventory. There was a significant interaction effect of group and time on neuroticism-related scales, indicating larger pre-to post-treatment reductions in the Internet-based CBT group compared to the control condition. Analyses at 6-month follow-up showed that changes were stable. Traits relating to extraversion and aggression were largely unchanged. This study is the first to demonstrate that a brief ICBT intervention for severe health anxiety causes long-term changes in measures of personality traits related to neuroticism. The treatment thus has a broader impact than just reducing health anxiety.
8.	Kindström Andersson, Karl, et al. (författare) System of systems lessons to be learned in the development of air power for the future : a small state’s perspective 2022 Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract Sweden, as a small alliance free state with powerful neighbors, has a military history of what we nowadays call systems of systems thinking. Since the beginning of the Cold War thishas been expressed in an air force on the forefront of exploiting military innovations, not least with regard to sensor networks, datalinks, information sharing and distributed decision making. How can this history and the lessons learned come to use when future systems and technologies are to be developed to meet the uncertain future and changing threats? How does this fit with current trends such as capability-based approach and system of systemsengineering methodology? What could this mean for the development of the next generation fighter aircraft - after the Gripen E and contemporary aircraft? These questions have been studied from both a government and industry perspective, following the trend in the defense sector of a more intertwined relationship between the two, necessitated by adopting acapability view on aircraft development. This paper presents preliminary lessons identified from a case study on the project Flygvapnet 2000 (FV2000), which preceded the Net Centric Warfare era at the turn of the millennium. The analysis was based on characteristics of best practice systems of systems engineering derived from a review of literature presenting the methodology theory on capability-based approaches for analyzing, acquiring, developing, and managing military capabilities. The findings from this project will contribute to the development of systems of systems engineering methods and will spur proposals for future research.

(författare) Distribution and Function of the Hydrogen Sulfide-Sensitive TRPA1 Ion Channel in Rat Urinary Bladder 2008 Ingår i: European Urology. - : Elsevier BV. - 0302-2838 .- 1873-7560. ; 53:2, s. 391-400 Tidskriftsartikel (refereegranskat)abstract Objectives: To investigate the distribution of the transient receptor potential (TRP) A1 ion channel in the rat urinary bladder, and to study the effects of hydrogen sulfide (H2S) and known TRPA1 activators on micturition in conscious rats and on heterologously expressed ion channels. Methods: The expression of TRPA1 in urinary bladder was studied with fluorescence immunohistochemistry and real-time PCR in female Sprague-Dawley rats. Cystometric investigations were performed in conscious animals subjected to intravesical administration of sodium hydrogen sulfide (NaHS, donor of H2S), allyl isothiocyanate (AI), and cinnamaldehyde (CA). Fluorometric calcium imaging was used to study the effect of NaHS on human and mouse TRPA1 expressed in CHO cells. Results: TRPA1 immunoreactivity was found on unmyelinated nerve fibres within the urothelium, suburothelial space, and muscle layer as well as around blood vessels throughout the bladder. All TRPA1 immunoreactive nerves fibres also expressed TRPV1 immunoreactivity and vice versa. TRPA1 was also detected in urothelial cells at both transcriptional and protein levels. AI increased micturition frequency and reduced voiding volume. CA and NaHS produced similar changes in urodynamic parameters after disruption of the urothelial barrier with protamine sulfate. NaHS also induced calcium responses in TRPA1-expressing CHO cells, but not in untransfected cells. Conclusions: The expression of TRPA1 on C-fibre bladder afferents and urothelial cells together with the finding that intravesical TRPA1 activators initiate detrusor overactivity indicate that TRPA1 may have a role in sensory transduction in this organ. The study also highlights H2S as a TRPA1 activator potentially involved in inflammatory bladder disease. © 2007.

12.	Abdelhady, Dalia, et al. (författare) The Nile and the Grand Ethiopian Renaissance Dam: Is There a Meeting Point between Nationalism and Hydrosolidarity? 2015 Ingår i: Journal of Contemporary Water Research and Education. - 1936-704X. ; 155:1, s. 73-82 Tidskriftsartikel (refereegranskat)abstract The soon-to-be completed Grand Ethiopian Renaissance Dam (GERD), which will be the largest hydroelectric power plant and among the largest reservoirs in Africa, has highlighted the need for expanding traditional integrated water resources management to better include the cultural, social, and political complexities of large water infrastructure in development projects. The GERD will store a maximum of 74 billion cubic meters of water corresponding to approximately the average annual outflow of the Nile from the Aswan high dam. Undoubtedly, the GERD will be vital for energy production and a key factor for food production, economic development, and poverty reduction in Ethiopia and the Nile Basin. However, the GERD is also a political statement that in one stroke has re-written the hydropolitical map of the Nile Basin. The GERD has become a symbol of Ethiopian nationalism or “renaissance” (hidase in Amharic). A contrasting concept to nationalism is hydrosolidarity. This concept has been put forward to better stress equitable use of water in international water management challenges that would lead to sustainable socioeconomic development. We use the opposing notions of nationalism and hydrosolidarity at three different scales, everyday politics, state policies, and interstate and global politics to analyse some aspects of the new hydropolitical map of the Nile Basin. We argue that nationalism and national interests are not necessarily negative standpoints but that there may instead be a meeting point where regional and national interests join with hydrosolidarity principles. We believe that this meeting point can maximize not only the common good, but also the good from a national interest point of view. For this, it is important not increase collaboration instead of being locked in to the historical narrative of nationalistic culture and historical discourse. This would benefit and improve future sustainability.

The MQW devices are intended for high speed intersubband electroabsorption modulator devices operating at 1.55-mu m. The GaN/AlN multiple quantum well material was systematically studied regarding the surface morphology, structural characterization and optical property by atomic force microscopy, X-ray diffraction and Fourier transform infrared spectroscopy, respectively. The intersubband resonance energy was also calculated considering many-body effects in n-type doped structures. The multiple quantum well structure showed superior performance in terms of linewidth when grown on GaN templates as compared on sapphire. GaN quantum well and AlN barriers with a thickness of 3.3 and 4.2 nm respectively resulted in FWHM of the intersubband absorption peak as low as 93 meV at an absorption energy of 700 meV. This is promising for intersubband modulator applications.
14.	Ahlford, Marianne, et al. (författare) Uppsala Underdogs - A Robot Soccer Project 2006 Rapport (populärvet., debatt m.m.)abstract In this paper, we describe the four-legged soccer team Uppsala Underdogs developed by a group of 4th year computer science students at Uppsala University during the fall of 2004. The project is based on the experience from two similar previous projects. This year the emphasis of the project has been on distribution of data and on support for evaluation and reconfiguration of strategies. To support data distribution, a middleware has been developed, which implements a replication algorithm and provides a clean interface for the other software modules (or behaviors). To enable easy reconfiguration of strategies, an automata-based graphical description language has been developed, which can be compiled into code that uses the database and the lower level modules, such as tactics and positioning, to make decisions and control the robot. In addition, a graphical simulator has been developed in which the strategies can be evaluated.

The code results are benchmarked against carefully analysed L-mode discharges at various density levels with and without impurity seeding in the full-metal tokamaks ASDEX Upgrade and JET. The role of the cross-field drifts and currents in the solutions is analysed in detail, and the improvements achieved by fully activating the drift and current terms in view of matching the experimental signals are addressed. The persisting discrepancies are also discussed.

(författare) Optimal allocation of design margins in additive remanufacturing 2021 Ingår i: Proceedings of the ASME Design Engineering Technical Conference. ; 3B-2021 Konferensbidrag (refereegranskat)abstract Often, coping with changing requirements results in substantial overdesign, because of the ways in which design margins are allocated at the beginning of the design process. In this paper, we present a design optimization method for minimizing overdesign using additive manufacturing. We use recently defined constituents of design margins (buffer and excess) as metrics in a design optimization problem to minimize overdesign. The method can be used to obtain optimal design decisions for changing requirements. We demonstrate our method by means of a turbine rear structure design problem where changes in the temperature loads are met by depositing different types of stiffeners on the outer casing. The optimal decisions obtained by optimization minimize overdesign but ensure that requirements are met throughout the product's lifecycle.

We present a design optimization method for minimizing overdesign by making use of additive remanufacturing and recently defined constituents of design margins (buffer and excess). The method can be used to obtain a set of design decisions for different changing requirement scenarios. We demonstrate our method by means of a turbine rear structure design problem where changes in the temperature loads are met by depositing different types of stiffeners on the outer casing. The results of the case study are visualized in a tradespace, which allows for comparison between sets of optimal, flexible, and robust designs. Results show that the optimized set of design decisions balances flexibility and robustness in a cost-effective manner.
18.	Al Handawi, Khalil, et al. (författare) Scalable set-based design optimization and remanufacturing for meeting changing requirements 2020 Ingår i: Proceedings of the ASME Design Engineering Technical Conference. ; 11A-2020 Konferensbidrag (refereegranskat)abstract Engineering design problems often have open-ended requirements, especially in the early stages of development. Setbased design is a paradigm for exploring, and keeping under consideration, several alternatives so that commitment to a single design can be delayed until requirements are settled. In addition, requirements may change over the lifetime of a component or a system. Novel manufacturing technologies enable designs to be remanufactured to meet changed requirements. By considering this capability during the set-based design optimization process, solutions can be scaled to meet evolving requirements and customer specifications even after commitment. Such an ability can also support a circular economy paradigm based on the return of used or discarded components and systems to working condition. We propose a set-based design methodology to obtain scalable optimal solutions that can satisfy changing requirements through remanufacturing. We first use design optimization and surrogate modeling to obtain parametric optimal designs. This set of parametric optimal designs is then reduced to scalable optimal designs by observing a set of transition rules for the manufacturing process used (additive or subtractive). The methodology is demonstrated by means of a structural aeroengine component that is remanufactured by direct energy deposition of a stiffener to meet higher loading requirements.

20.	Albrecht, Knut, et al. (författare) Immunohistochemical distribution of cyclic nucleotide phosphodiesterase (PDE) isoenzymes in the human vagina: : A potential forensic value? 2007 Ingår i: Journal of forensic and legal medicine. - : Elsevier BV. - 1752-928X. ; 14:5, s. 270-274 Tidskriftsartikel (refereegranskat)abstract Objectives Phosphodiesterase (PDE) isoenzymes are key proteins involved in the maintenance of the normal function of various tissues of the human body including those of the male and female urogenital tract. More recently, PDEs and their main substrates, cyclic GMP and cyclic AMP, have also been assumed to play a crucial role in the control of the human vagina. In order to elucidate the potential significance of phosphodiesterases as marker proteins in female genital organs, it was the aim of the present study to evaluate by means of immunohistochemistry the distribution of cGMP- and cAMP-PDE isoenzymes in specimens of the human vagina. Methods Conventional immunohistochemical techniques (double antibody technique, laser fluorescence microscopy) were applied to sections of the human vaginal wall in order to evaluate the presence of the PDE isoenzymes 1, 2, 3, 4, 5 and 10. Results Immunoreactivities (IR) specific for PDE1 (cAMP/cGMP-PDE, Ca2+/Calmodulin-dependent), PDE2 (cAMP-PDE, cGMP-dependent) and PDE5 (cGMP-PDE) were exclusively registered in the smooth musculature of vaginal arterial vessels, whereas no signals were detected in non-vascular tissue. IR indicating the expression of the cAMP-degrading PDE4 was mainly observed in the vaginal epithelium. Vaginal epithelial cells also presented immunosignals specific for PDE3 (cAMP-PDE, inhibited by cGMP) and PDE10 (dual substrate PDE), nevertheless, these stainings were less abundant than those related to the PDE4. IR for PDE10 was also registered in inflammatory cells located in the subepithelial region of the vaginal wall. Conclusion Our study revealed the presence of IR specific for PDE1, PDE2, PDE4, PDE5 and PDE10 in sections of the human vagina and demonstrated that these enzymes are not evenly distributed in the tissue. Especially, the prominent expression of the cyclic AMP-PDE4A in the vaginal epithelium may give hint to a potential significance of this isoenzyme as a forensic marker protein. The findings give a rationale to investigate further as to whether the immunohistochemical detection of PDE4 may represent a new forensic tool in order to identify human vaginal epithelial cells.

R24- Tidskriftsartikel (refereegranskat)abstract Background We have developed genomic tools to allow the genus Populus (aspens and cottonwoods) to be exploited as a full-featured model for investigating fundamental aspects of tree biology. We have undertaken large-scale expressed sequence tag (EST) sequencing programs and created Populus microarrays with significant gene coverage. One of the important aspects of plant biology that cannot be studied in annual plants is the gene activity involved in the induction of autumn leaf senescence. Results On the basis of 36,354 Populus ESTs, obtained from seven cDNA libraries, we have created a DNA microarray consisting of 13,490 clones, spotted in duplicate. Of these clones, 12,376 (92%) were confirmed by resequencing and all sequences were annotated and functionally classified. Here we have used the microarray to study transcript abundance in leaves of a free-growing aspen tree (Populus tremula) in northern Sweden during natural autumn senescence. Of the 13,490 spotted clones, 3,792 represented genes with significant expression in all leaf samples from the seven studied dates. Conclusions We observed a major shift in gene expression, coinciding with massive chlorophyll degradation, that reflected a shift from photosynthetic competence to energy generation by mitochondrial respiration, oxidation of fatty acids and nutrient mobilization. Autumn senescence had much in common with senescence in annual plants; for example many proteases were induced. We also found evidence for increased transcriptional activity before the appearance of visible signs of senescence, presumably preparing the leaf for degradation of its components.

(författare) Inline Process Control – a concept study of efficient in-line process control and process adjustment with respect to product geometry 2016 Ingår i: Swedish Production Symposium 2016 SPS 2016. - Lund, Sweden. Konferensbidrag (refereegranskat)abstract All manufacturing processes have variation which may violate the fulfillment of assembly, functional, geometrical or esthetical requirements and difficulties to reach desired form in all areas. The cost for geometry defects rises downstream in the process chain. Therefore, it is vital to discover these defects as soon as they appear. Then adjustments can be done in the process without losing products or time. In order to find a solution for this, a project with the overall scope “development of an intelligent process control system” has been initiated. This project consists of five different work packages: Inline measurement, Process Evaluation, Corrective actions, Flexible tooling and demonstrator cell. These work packages address different areas which are necessary to fulfill the overall scope of the project. The system shall both be able to detect geometrical defects, propose adjustments and adjust simple process parameters. The results are demonstrated in a demo cell located at Chalmers University of Technology. In the demonstrator all the different areas have been verified in an industrial case study – assembly of GOR Volvo S80. Efficient offline programming for robot based measurement, efficient process evaluation based on case base reasoning (CBR) methodology, flexible fixtures and process adjustments based on corrective actions regarding in going part positioning.

They gradually become more important for Interaction Design due to increased development of tangible interaction and mobile communication. In this paper we present and discuss our work with voice and tangible interaction in our ongoing research project RHYME. The goal is to improve health for families, adults and children with disabilities through use of collaborative, musical, tangible media. We build on the use of voice in Music Therapy and on a humanistic health approach. Our challenge is to design vocal and tangible interactive media that through use reduce isolation and passivity and increase empowerment for the users. We use sound recognition, generative sound synthesis, vibrations and cross-media techniques to create rhythms, melodies and harmonic chords to stimulate voice-body connections, positive emotions and structures for actions.

We describe the composition process of how we decompose a linear beat-based and vocal sound material and recompose it with real-time audio synthesis and composition rules into interactive Scenes. Scenes that make it possible for the users to select, explore and recreate different sound worlds. In order to recreate, the users interact with the tangible interface in different ways, as instrument, play with it as a friend, improvise and create music and relax with it as ambient sounding furniture. We discuss composition techniques for mixing sound, tangible-physical and lighting elements in the Scenes. Based on observations we explore how a diverse audience in the family and at school can recreate and improvise their own sound experience and play together in open and non-therapeutic everyday situations. We conclude by discussing the possible impact of our findings for the NIME-community; how the techniques of decomposing, recomposing and recreating sound, based on a relational perspective, could contribute to the design of new instruments for musical expression.

In order to recreate, the users interact with the tangible interface in different ways, as instrument, play with it as a friend, improvise and create music and relax with it as ambient sounding furniture. We discuss composition techniques for mixing sound, tangible-physical and lighting elements in the Scenes. Based on observations we explore how a diverse audience in the family and at school can recreate and improvise their own sound experience and play together in open and non-therapeutic everyday situations. We conclude by discussing the possible impact of our findings for the NIME-community; how the techniques of decomposing, recomposing and recreating sound, based on a relational perspective, could contribute to the design of new instruments for musical expression.

29.	Andersson, Anders-Petter (författare) Interactive Music Composition 2012 Doktorsavhandling (populärvet., debatt m.m.)abstract This dissertation, titled Interactive Music Composition, is a practice based Ph.D. thesis in the field of Musicology. The purpose is to explore if and how one can compose computer based interactive music, that is musically satisfying for an interacting audience, consisting of both laymen and skilled musicians. The text describes the design and reflection in two interactive music installations: Do-Be-DJ, open-air installation in a public park, and, Mufi, with modular and moveable interface. Based on methods and perspectives in Musicology and Interaction Design, a composition model for interactive music is developed. The model investigates the experience dimensions listen, explore, compose and collaborate. It also investigates the design dimensions of interaction, narrative structure, composition rule and sound node. The conceptual approach is to apply improvisation and composition methods from jazz, pop and groove based music on interactive music. It also uses the concepts of openess in musical structures and interpretation, musical mediation of actions and meaning and everyday use of music, when composing interactive music. The dissertation contributes to an understanding of how to create composition techniques for interactive music, such as: Direct, varied and shifting response. It reflects on the change in meaning of the musicological terms composition, improvisation, musical work, listener, musician and audience. And on the interaction design terms interaction, gameplay, system and user. The term co-creator is used to describe an actively, interacting and collaborating person, to complement traditional terms like audience, performer and user.

Interactive audio has become an important design quality in commercially successful games like Guitar Hero , and a range of mobile phone applications motivating people to interact, play, dance, and collaborate with music. Parallel to the game, phone, and art scenes, an area of music and health research has grown, showing the positive results of using music to promote health and wellbeing in everyday situations and for a broad range of people, from children and elderly to people with psychological and physiological disabilities. Both quantitative medical and ecological humanistic research show that interaction with music can improve health, through music’s ability to evoke feelings, motivate people to interact, master, and cope with difficult situations, create social relations and experience shared meaning. Only recently, however, the music and health field has started to take interest in interactive audio, based on computer-mediated technologies’ potential for health improvement. Here, we show the potential of using interactive audio in what we call interactive musicking in the computer-based interactive environment Wave. Interactive musicking is based on musicologist Christopher Small’s concept “musicking”, meaning any form of relation-building that occurs between people, and people and things, related to activities that include music. For instance, musicking includes dancing, listening, and playing with music (in professional contexts and in amateur, everyday contexts). We have adapted the concept of "musicking" on the design of computer-based musical devices. The context for this chapter is the research project RHYME. RHYME is a multidisciplinary collaboration between the Centre for Music and Health at the Norwegian Academy of Music, the Oslo School of Architecture and Design (AHO), and Informatics at the University of Oslo. Our target group is families with children with severe disabilities. Our goal is to improve health and wellbeing in the families through everyday musicking activities in interactive environments. Our research approach is to use knowledge from music and health research, musical composition and improvisation, musical action research, musicology, music sociology, and soundscape studies, when designing the tangible interactive environments. Our focus here is interaction design and composition strategies, following research-by-design methodology, creating interactive musicking environments. We describe the research and design of the interactive musicking environment Wave, based on video documentation, during a sequence of actions. Our findings suggest some interactive audio design strategies to improve health. We base the design strategies on musical actions performed while playing an instrument, such as impulsive or iterative hitting, or sustainable stroking of an instrument. Musical actions like these can also be used for musicking in everyday contexts, creating direct sound responses to evoke feelings that create expectations and confirm interactions. In opposition to a more control-oriented, instrument and interface perspective, we argue that musical variation and narrative models can be used to design interactive audio, where the audio is seen as an actor taking many different roles, as instrument, co-musician, toy, etc. In this way, the audio and the interactive musicking environments will change over time, answering with direct response, as well as nose-thumbing and changing response, motivating creation, play, and social interaction. Musical variation can also be used to design musical backgrounds and soundscapes that can be used for creating layers of ambience. These models create a safe environment and contribute to shared meaning.

Instead of writing one linear work, he creates infinite numbers of potential musics that reveal themselves as answers to user interactions in many situations. Therefore, we have to broaden our perspectives. We have to put forward factors that earlier was implicit in the musical and music making situations, no matter if it was the concert hall, the church, or the club. When composing interactive music we have to consider the genre, the potential roles the listener might take, and the user experience in different situations.

Att komponera musik som både är intressant och samtidigt flexibelt rättar sig efter en publik som fysiskt medverkar till att skapa musiken är kanske vår tids största utmaning för nu verksamma musiker, tonsättare och dramatiker.

Darwinian forces are seen as necessary but not sufficient for explaining observed evolutionary patterns. We here propose that the same arguments apply with even greater force to culture vis-à-vis cultural evolution. In order not to argue entirely in the abstract, we demonstrate the proposed approach by combining a set of different models into a provisional synthetic theory, and by applying this theory to a number of short case studies. What emerges is a set of concepts and models that allow us to consider entirely new types of explanations for the evolution of cultures. For example we see how feedback relations - both within societies and between societies and their ecological environment - have the power to shape evolutionary history in profound ways. The ambition here is not to produce a definite statement on what such a theory should look like but rather to propose a starting point along with an argumentation and demonstration of its potential.

But Darwinism is not the only process of evolution that needs to be included. Evolutionary biology itself has taken such a turn recently, with the emergence of developmental evolutionary approaches.

The question of how human culture as opposed to its animal counter parts came to become open-endedly creative and cumulative is therefore one of wide and general scientific importance. Several causal factors have been proposed to date to explain this unique quality, including population size, transmission fidelity, pedagogy, and creativity. Inquiries, however, tend to focus exclusively on one factor at a time, leaving us blind to important issues regarding their relative roles and combined action. We here combine two models, one focusing on population size and the other on imitation fidelity, as constraints and enablers of evolutionary cumulativity. We explore how these factors interact to promote and inhibit evolutionary cumulativity and how the synthetic model compares to the original models individually and to empirical and experimental data. We report several findings that do not emerge in the models that we combine individually. For example, group size is found to be important for small but not for larger groups, an observation that moreover substantially improves agreement with data.

We address the problem that societal systems remain recalcitrant despite the development of powerful approaches for dealing with both of these qualities. The root of this problem we identify to be that the combination between complexity and complicatedness is emergent; i.e. fundamentally and irreducibly different from either quality in isolation. This means that neither class of such approaches can be expected to work well on their own. But it also means that the obvious strategy of combining theory for complexity and complicatedness may be much more challenging than envisioned. In short, systems where complexity and complicatedness is mixed ought to be treated as a distinct class of systems. Noting a connection to what has long been called "wicked problems" we hereby outline such a class of systems that we call "wicked systems". We introduce a simple model and heuristic and discuss some implications for theorizing and modeling.

Here, we make the radical proposition that the cultural communities within which Homo emerged may be understood as a novel exotic form of organism. The argument begins from a deep congruence between robust features of Pan community life cycles and protocell models of the origins of life. We argue that if a cultural tradition, meeting certain requirements, arises in the context of such a “social protocell,” the outcome will be an evolutionary transition in individuality whereby traditions and hominins coalesce into a macroscopic bio-socio-technical system, with an organismal organization that is culturally inherited through irreversible fission events on the community level. We refer to the resulting hypothetical evolutionary individual as a “sociont.” The social protocell provides a preadapted source of alignment of fitness interests that addresses a number of open questions about the origins of shared adaptive cultural organization, and the derived genetic (and highly unusual) adaptations that support them. Also, social cooperation between hominins is no longer in exclusive focus since cooperation among traditions becomes salient in this model. This provides novel avenues for explanation. We go on to hypothesize that the fate of the hominin in such a setting would be mutualistic coadaptation into a part-whole relation with the sociont, and we propose that the unusual suite of derived features in Homo is consistent with this hypothesis.

In response to these shortcomings, a new wave of approaches has emerged based on the idea that societal systems are irreducibly complex. The new categories that are thereby introduced – like “complex” or “wicked” – suffer, however, by a lack of shared understanding. We here aim to reduce this confusion by developing a meta-ontological map of types of systems that have the potential to “overwhelm us”: characteristic types of problems, attributions of function, manners of design and governance, and generating and maintaining processes and phenomena. This permits us, in a new way, to outline an inner anatomy of the motley collection of system types that we tend to call “complex”. Wicked problems here emerge as the product of an ontologically distinct and describable type of system that blends dynamical and organizational complexity. The framework is intended to provide systematic meta-theoretical support for approaching complexity and wickedness in policy and design. We also points to a potential causal connection between innovation and wickedness as a basis for further theoretical improvement.

By exploiting variation in paydays across work-places, we completely control for mortality patterns related to, for example, public holidays and other special days or events coinciding with paydays and for general within-month and within-week mortality patterns. We find a dramatic increase in mortality on the day that salaries arrive. The increase is especially pronounced for younger workers and for deaths due to activity-related causes such as heart conditions and strokes. The effect is entirely driven by an increase in mortality among low income individuals, who are more likely to experience liquidity constraints. All things considered, our results suggest that an increase in general economic activity on salary receipt is an important cause of the excess mortality.

(författare) Prevalence of diabetes and hospitalization due to poor glycemic control in people with bladder cancer or renal cell carcinoma in Sweden 2024 Ingår i: BMC Urology. - : BioMed Central (BMC). - 1471-2490. ; 24:1 Tidskriftsartikel (refereegranskat)abstract Background: Bladder cancer (BC) and Renal cell carcinoma (RCC) are the most common urogenital cancers among both sexes, with a yearly global incidence of around 500 000 each. Both BC and RCC have been linked to diabetes. Poor glycemic control (malglycemia) is a serious consequence of diabetes and a possible consequence of systemic treatments used in BC and RCC. The objective of this study was to investigate the prevalence of diabetes and use of hospital-based care for malglycemia in people with BC or RCC.Methods: This Swedish retrospective population-based register study used national health-data registers for longitudinal data on cancer incidence covering 15 years, use of hospital-based health care, and filled prescriptions of outpatient medications. Study endpoints included co-prevalence of diabetes in individuals with BC/RCC, healthcare resource utilization due to malglycemia, use of systemic corticosteroids, and changes in diabetes management for people with concomitant type 2 diabetes.Results: We identified 36,620 and 15,581 individuals diagnosed with BC and RCC, respectively, between 2006 and 2019. The proportion of individuals registered with diabetes was 24% in BC and 23% in RCC. An association between BC/RCC and poor glycemic control was found, although the number of malglycemic events in hospital-based care were few (65/59 per 1000 individuals with diabetes and BC/RCC respectively with at least one event). An earlier switch to insulin-based diabetes management was observed in BC/RCC compared to matched individuals with type 2 diabetes but no cancer. The results also indicated an association between steroid treatment and poor glycemic control, and that systemic corticosteroids were more common among people with BC/RCC compared to diabetes controls.Conclusion: The high prevalence of diabetes and increased use of systemic corticosteroid treatment observed in this large national study highlights the need for specific clinical management, risk-assessment, and monitoring of individuals with BC/RCC and diabetes.
