- OBJECTIVE: To develop, evaluate, and apply a questionnaire-based instrument for investigation of specific symptoms in idiopathic environmental intolerance (IEI), called the Idiopathic Environmental Intolerance Symptom Inventory (IEISI). METHODS: Participants with IEI to chemicals responded to 82 candidate symptoms and to three subscales of the Quick Environmental Exposure and Sensitivity Inventory (QEESI) at a test (n = 207) and retest (n = 193) occasion. RESULTS: The 27 most commonly reported symptoms were selected and grouped into five symptom categories. Internal consistency, test-retest reliability, and concurrent validity were found to be satisfying. Cluster analysis identified two subgroups of IEI to chemicals. CONCLUSIONS: The results provide support for the IEISI being a reliable, valid, and fast tool for the study of specific symptom prevalence in IEI and encourage further study of subgroups.

- In this study we aimed to estimate the effect of diabetes, educational level and income on the risk of mortality and cardiovascular events in primary care patients with hypertension.We followed 62,557 individuals with hypertension diagnosed 2001-2008, in the Swedish Primary Care Cardiovascular Database. Study outcomes were death, myocardial infarction, and ischemic stroke, assessed using national registers until 2012. Cox regression models were used to estimate adjusted hazard ratios of outcomes according to diabetes status, educational level, and income.During follow-up, 13,231 individuals died, 9981 were diagnosed with diabetes, 4431 with myocardial infarction, and 4433 with ischemic stroke. Hazard ratios (95% confidence intervals) for diabetes versus no diabetes: mortality 1.57 (1.50-1.65), myocardial infarction 1.24 (1.14-1.34), and ischemic stroke 1.17 (1.07-1.27). Hazard ratios for diabetes and ≤9 years of school versus no diabetes and >12 years of school: mortality 1.56 (1.41-1.73), myocardial infarction 1.36 (1.17-1.59), and ischemic stroke 1.27 (1.08-1.50). Hazard ratios for diabetes and income in the lowest fifth group versus no diabetes and income in the highest fifth group: mortality 3.82 (3.36-4.34), myocardial infarction 2.00 (1.66-2.42), and ischemic stroke 1.91 (1.58-2.31).Diabetes combined with low income was associated with substantial excess risk of mortality, myocardial infarction and ischemic stroke among primary care patients with hypertension.

- BACKGROUND: The safety of pancreatic resection for elderly patients is still controversial. We examined the postoperative morbidity and mortality in patients aged 75 years or more undergoing pancreatic resection.METHODS: Patients undergoing pancreatic resection were studied retrospectively and the outcomes were compared between patients aged <75 and ≥75 years.RESULTS: Of the 556 patients enrolled, 78 (14%) were ≥75 years old. Elderly patients had significantly more co-morbidities, especially cardiovascular pathology (P=0.005). Also, elderly patients had significantly lower body mass index prior to surgery (P=0.005). There were no significant differences in terms of surgical procedures and tumor types between age groups. The incidence of postoperative pancreatic fistula grade A was significantly lower in the elderly group (P=0.022), but no significant differences were noted in the overall morbidity or the incidence of postpancreatectomy hemorrhage, delayed gastric emptying, bile leakage, cardiac complications, pulmonary complications or septic complications. The 30-day mortality rate was similar between groups (0.8% vs. 1.3%; P=0.532).CONCLUSION: Pancreatic resection is a safe option for selected elderly patients. Our study confirms that age alone should not preclude potentially curative surgical therapy.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Glycoproteomics is an emerging subfield of proteomics. Tumor-specific variations in protein glycosylation might be potential targets for the development of new cancer diagnostics. Here, we performed high-throughput screening and targeted verification of glycome alterations in serum samples from patients with pancreatic cancer and the precancerous lesion intraductal papillary mucinous neoplasm (IPMN). Material and methods: The glycosylation profile of 1000 proteins was mapped in a discovery cohort comprising serum samples from 16 individuals, including 8 patients with pancreatic cancer and 8 healthy controls. The top 10 glycoprotein biomarker candidates with the highest signal intensity difference in glycosylation levels were evaluated in a cohort consisting of 109 serum samples, including 49 patients with resectable pancreatic cancer, 13 patients with resectable noninvasive IPMN and 47 healthy controls, using a targeted assay. Results: Multivariable analysis defined sets of panels comprising CA19-9 and distinctively glycosylated proteins for discrimination between pancreatic cancer, IPMN and healthy controls. A panel including CA 19-9, IL.17E, B7.1 and DR6 gave an AUC of 0.988 at 100% sensitivity at 90% specificity for the discrimination of stage 1 pancreatic cancer and healthy controls. B7.1 was found to be a valuable biomarker for differentiating between IPMN and healthy controls, with better performance alone than CA 19-9. Conclusions: Measurement of protein glycosylation profiles in serum may aid in the early detection of pancreatic cancer and precursor lesions.

Tidskriftsartikel (refereegranskat)abstract
- Background: Branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) presents a clinical conundrum. Rigorous long-term surveillance or surgical resection is recommended. The economic consequences of the management have not been fully investigated. Methods: A Markov decision model compared 4 strategies for low-risk BD-IPMN: I = upfront total pancreatectomy, II = upfront partial pancreatectomy, III = initial surveillance, IV = watchful waiting. Surveillance was based on the Swedish Guidelines for Pancreatic Cancer. Probabilities and costs were obtained from the participating unit and from the scientific literature. The incremental cost-effectiveness ratios (ICERs) were calculated and sensitivity analyses were performed by varying relevant parameters. Survival was reported in quality-adjusted life-years (QALYs). Results: Strategy III was the most cost-effective strategy with an ICER of €31 682 compared to strategy IV. Strategy I was the most expensive but yielded the best QALY (9.32). Total number of years, annual risk of pancreatic cancer and annual risk of a low-risk BD-IPMN turning into a high-risk lesion had the greatest impact in the model. Conclusions: Initial surveillance seems to be the most cost-effective strategy in the management of low-risk asymptomatic BD-IPMN. However, the possibility of personalized approaches remains to be investigated.

Tidskriftsartikel (refereegranskat)abstract
- Background Overweight, defined by body mass index (BMI), is correlated to complications following pancreaticoduodenectomy (PD). The aim of this study was to evaluate the impact of body constitution, measured with different anthropometric measures, and diabetes on complications following PD. Materials and methods Patients who underwent PD between 2000 and 2015 at Skåne University Hospital were retrospectively included. Body mass index (BMI), body surface area (BSA) and body fat percentage (BF%) were calculated. Overweight and obesity were defined by BMI according to the WHO classification (overweight ≥25 and obesity ≥30). Values equal to or above the median value were considered as large by BSA (≥1.87) and overweight by BF% (≥29.6% (male) and ≥38.9% (female)). Main endpoints were events of postoperative pancreatic fistula (POPF), post pancreatectomy hemorrhage (PPH), delayed gastric emptying (DGE) and complications classified according to the Clavien-Dindo classification. Multivariable analysis was performed using logistic regression and a subgroup analysis on diabetic patients was performed. Results In total 328 patients were included. The incidence of POPF grades B and C was increased among overweight and large patients defined by BMI (OR 4.16; p = 0.001), BSA (OR 2.88; p = 0.018) and BF% (OR 3.94; p = 0.001). However, the risk was not increased among diabetic patients with BMI≥25 and BMI≥30. DGE and complications classified as Clavien grade ≥3 were more common in patients defined as overweight by both BMI (OR 1.72; p = 0.024 and OR 2.63; p = 0.003, respectively) and BF% (OR 2.13; p = 0.001 and OR 2.31; p = 0.009, respectively). PPH was not more frequent in overweight or large patients. Conclusion Body constitution has an impact on the risk of severe complications following PD. BMI, BSA and BF% can all be used to identify risk groups. The risk of developing POPF grades B and C was significantly increased in overweight and large patients, but not in patients with coexisting diabetes.

Tidskriftsartikel (refereegranskat)abstract
- Background: Olfactory dysfunction together with neurological and cognitive symptoms are common after COVID-19. We aimed to study whether performance on olfactory and neuropsychological tests following infection predict post-COVID condition (PCC), persisting symptoms, and reduced health-related quality of life.Methods: Both hospitalized (N = 10) and non-hospitalized individuals (N = 56) were enrolled in this prospective cohort study. Participants were evaluated 1–3 months after infection with an olfactory threshold test and neuropsychological tests, which was used as predictors of PCC. A questionnaire outlining persisting symptoms and the validated instrument EuroQol five-dimension five-level for health-related quality of life assessment were used as outcome data 1 year after infection (N = 59). Principal component analysis was used to identify relevant predictors for PCC at 1 year.Results: Objectively assessed olfactory dysfunction at 1–3 months post infection, but not subjective olfactory symptoms, predicted post-COVID condition with reduced health-related quality of life (PCC+) at 1 year. The PCC+ group scored more often below the cut off for mild cognitive impairment on the Montreal Cognitive Assessment (61.5% vs. 21.7%) and higher on the Multidimensional Fatigue Inventory-20, compared to the group without PCC+.Conclusion: Our results indicate that objectively assessed, olfactory dysfunction is a predictor for PCC+. These findings underscore the importance of objective olfactory testing. We propose that olfactory screening in the early post-acute phase of COVID-19 infection might identify individuals that are at higher risk of developing long-term health sequalae.

Tidskriftsartikel (refereegranskat)abstract
- Sometimes we seem to look at the very object we are searching for, without consciously seeing it. How do we select object relevant information before we become aware of the object? We addressed this question in two recognition experiments involving pictures of fragmented objects. In Experiment 1, participants preferred to look at the target object rather than a control region 25 fixations prior to explicit recognition. Furthermore, participants inspected the target as if they had identified it around 9 fixations prior to explicit recognition. In Experiment 2, we investigated the influence of semantic knowledge in guiding object inspection prior to explicit recognition. Consistently, more specific knowledge about target identity made participants scan the fragmented stimulus more efficiently. For instance, non-target regions were rejected faster when participants knew the target object's name. Both experiments showed that participants were looking at the objects as if they knew them before they became aware of their identity.

- The nearly exponential growth in the molecular imprinting literature has to a large extent been fuelled by an increasing awareness of the potential of molecular imprinting based technologies. Despite the acceptance of the technique by cognate disciplines and the demonstration of its usefulness in a number of enabling technologies, relatively little is known about the molecular level events underlying the imprinting process and subsequent recognition events. What rules govern imprint formation? Can we use such rules to rationally design molecularly imprinted polymers?

- Indications of adverse effects of nontoxic malodorous chemical exposure on work performance and safety and the role of health-risk perception on odor perception motivated the present study of the impact of health-risk perception on odor perception and cognitive performance. Healthy young adults were informed that they were to be exposed to an odorous substance that is either potentially health-enhancing (positive information bias, n = 24) or hazardous (negative information bias, n = 25). The two groups, screened for loss in odor-detection sensitivity, were matched for age, sex, chemical intolerance, and negative affectivity. During each of 14 trials of exposure to 433 mg/m(3) of n-butanol, the participants rated the intensity and valence of odor perception and performed a cognitive task that taxed working memory and attention. The results showed that the negative-bias group rated the odor perception as more unpleasant than did the positive-bias group during the entire session, but significantly more unpleasant only during the first half of the session. The negative-bias group was also found to perform significantly poorer on the cognitive task during both halves of the session. No effect of information bias was found on perceived odor intensity. The results provide experimental support for the hypotheses that belief that exposure to an odorous chemical is hazardous contributes to the odor perception being more unpleasant and to poorer cognitive performance.

- Being the second leading cause of death and the leading cause of disability-adjusted life years worldwide, infectious diseases remain─contrary to earlier predictions─a major consideration for the public health of the 21st century. Resistance development of microbes to antimicrobial drugs constitutes a large part of this devastating problem. The most widely spread mechanism of bacterial resistance operates through the degradation of existing β-lactam antibiotics. Inhibition of metallo-β-lactamases is expected to allow the continued use of existing antibiotics, whose applicability is becoming ever more limited. Herein, we describe the synthesis, the metallo-β-lactamase inhibition activity, the cytotoxicity studies, and the NMR spectroscopic determination of the protein binding site of phosphonamidate monoesters. The expression of single- and double-labeled NDM-1 and its backbone NMR assignment are also disclosed, providing helpful information for future development of NDM-1 inhibitors. We show phosphonamidates to have the potential to become a new generation of antibiotic therapeutics to combat metallo-β-lactamase-resistant bacteria.

Combinations of mutations in envZ, ftsI, mrdA, acrB and acrR can cause high-level carbapenem resistance in Escherichia coli

-

Tidskriftsartikel (refereegranskat)abstract
- The worldwide spread of ESBL-producing Enterobacteriaceae has led to an increased use of carbapenems, the group of beta-lactams with the broadest spectrum of activity. Bacterial resistance to carbapenems is mainly due to acquired carbapenemases or a combination of ESBL production and reduced drug influx via loss of outer-membrane porins. Here, we have studied the development of carbapenem resistance in Escherichia coli in the absence of beta-lactamases. We selected mutants with high-level carbapenem resistance through repeated serial passage in the presence of increasing concentrations of meropenem or ertapenem for similar to 60 generations. Isolated clones were whole-genome sequenced, and the order in which the identified mutations arose was determined in the passaged populations. Key mutations were reconstructed, and bacterial growth rates of populations and isolated clones and resistance levels to 23 antibiotics were measured. High-level resistance to carbapenems resulted from a combination of downstream effects of envZ mutation and target mutations in AcrAB-TolC-mediated drug export, together with PBP genes [mrdA (PBP2) after meropenem exposure or ftsI (PBP3) after ertapenem exposure]. Our results show that antibiotic resistance evolution can occur via several parallel pathways and that new mechanisms may appear after the most common pathways (i.e. beta-lactamases and loss of porins) have been eliminated. These findings suggest that strategies to target the most commonly observed resistance mechanisms might be hampered by the appearance of previously unknown parallel pathways to resistance.

High Fitness Costs and Instability of Gene Duplications Reduce Rates of Evolution of New Genes by Duplication-Divergence Mechanisms
- 2014
-

Tidskriftsartikel (refereegranskat)abstract
- An important mechanism for generation of new genes is by duplication-divergence of existing genes. Duplication-divergence includes several different sub-models, such as subfunctionalization where after accumulation of neutral mutations the original function is distributed between two partially functional and complementary genes, and neofunctionalization where a new function evolves in one of the duplicated copies while the old function is maintained in another copy. The likelihood of these mechanisms depends on the longevity of the duplicated state, which in turn depends on the fitness cost and genetic stability of the duplications. Here, we determined the fitness cost and stability of defined gene duplications/amplifications on a low copy number plasmid. Our experimental results show that the costs of carrying extra gene copies are substantial and that each additional kbp of DNA reduces fitness by approximately 0.15%. Furthermore, gene amplifications are highly unstable and rapidly segregate to lower copy numbers in absence of selection. Mathematical modelling shows that the fitness costs and instability strongly reduces the likelihood of both sub- and neofunctionalization, but that these effects can be off-set by positive selection for novel beneficial functions.

Influence of acquired β-lactamases on the evolution of spontaneous carbapenem resistance in Escherichia coli

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To investigate the influence of plasmid-borne β-lactamases on the evolution of spontaneous carbapenem resistance in Escherichia coli and the fitness costs associated with resistance. Methods: Stepwise selection of carbapenem-resistant mutants with or without the extended-spectrum β-lactamase (ESBL)-encoding plasmid pUUH239.2 was performed. Mutation rates and mutational pathways to resistance were determined. In vitro-selected and constructed mutants were characterized regarding the MICs of the carbapenems, porin expression profiles, growth rates and the presence of mutations in the porins ompC/ompF and their regulatory genes. The influence of the plasmid-encoded β-lactamases TEM-1, OXA-1 and CTX-M-15 on resistance development was determined. Results: Results show that E. coli readily developed reduced carbapenem susceptibility and clinical resistance levels by a combination of porin loss and increased β-lactamase expression, especially towards ertapenem. All tested β-lactamases (CTX-M-15, TEM-1 and OXA-1) contributed to reduced carbapenem susceptibility in the absence of porin expression. However, complete loss of porin expression conferred a 20% fitness cost on the bacterial growth rate. Increased β-lactamase expression through spontaneous gene amplification on the plasmid was a major resistance factor. Conclusions: Plasmid-encoded β-lactamases, including non-ESBL enzymes, have a strong influence on the frequency and resistance level of spontaneous carbapenem-resistant mutants. The fitness cost associated with the loss of OmpC/OmpF in E. coli most likely reduces the survivability of porin mutants and could explain why they have not emerged as a clinical problem in this species.

Mutation in the Copper-Induced sil Operon Enables High-Level Silver Resistance and Silver Facilitated Co-Selection of Multidrug Resistance Plasmid
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Human activities are responsible for an accumulation of metals in health care and agricultural environments, and plasmid-encoded metal tolerance operons enable bacteria to rapidly adapt to metal exposure under such conditions. While the mechanisms of action of many metal resistance systems have been described, there is still limited understanding of their role in co-selection of antibiotic resistance in metal-containing environments. Whether plasmid-encoded metal resistance genes confer significant selective advantages is of interest as it has implications for plasmid enrichment and the spread of plasmid-borne antibiotic resistance genes. To increase our understanding of plasmid-mediated metal resistance, we studied the sil operon and its phenotypes in E. coli during growth in the absence and presence of silver and copper. We found that the sil operon provides resistance to both silver and copper. However, it is induced by copper only, and constitutive expression due to point mutations in the two-component silS gene provides high-level silver resistance. Furthermore, we showed that a high-level silver resistant mutant could be enriched in the presence of silver. This enrichment entailed co-selection of the multidrug resistance plasmid pUUH239.2. Our results show that a copper resistance operon can provide high-level silver resistance following a single point mutation, and that the silver resistance phenotype subsequently can co-select for antibiotic resistance in the presence of silver.

A Method for Synthesizing Iron Silicate Slags to Evaluate Their Performance as Supplementary Cementitious Materials
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Utilizing iron silicate copper slag as supplementary cementitious material (SCM) is a means to improve resource efficiency and lower the carbon dioxide emissions from cement production. Despite multiple studies on the performance of these slags in SCM applications, the variations in cooling procedure, grinding, and methods for evaluating reactivity limit the ability to assess the influence of chemical composition on reactivity from the literature data. In this study, a methodology was developed to synthesize iron silicate slags, which were then evaluated for their inherent reactivity using the R-3 calorimeter-based experiments. The results demonstrated that laboratory-scale granulation produced the same reactivity as industrially granulated slag. Furthermore, a synthesized triplicate sample showed high repeatability. Based on these two aspects, this method can be used to systematically study the influence of chemical composition on the inherent reactivity of iron silicate slags while producing results that are directly translatable to industrial slags.

- Automated and connected traffic systems with cooperative functionality need effective testing. One way to enable such testing is to represent the current traffic environment by co-simulating different simulators using a communication layer between the simulators for cooperative functionality. With this approach, this paper presents a platform with its included simulators (vehicle, pedestrian, and traffic simulators), the used run-time infrastructure (RTI) for co-simulation, and the connection to the Unreal Engine based visual system for the simulators. The architecture was tested with two vehicle simulators (one autonomous bus and a truck), one pedestrian simulator, and one traffic simulator connected using a cloud-based service for the RTI.

Ingår i: Journal of Sailboat Technology. ; 2018, s. 1-24

Tidskriftsartikel (refereegranskat)abstract
- Because of the successful application of hydrofoils on the America's Cup catamarans in the past two campaigns the interest in foiling sailing craft has boosted. Foils have been fitted to a large number of yachts with great success, ranging from dinghies to ocean racers. An interesting question is whether one of the slowest racing boats in the world, the Optimist dinghy, can foil, and if so, at what minimum wind speed. The present paper presents a comprehensive design campaign to answer the two questions. The campaign includes a newly developed Velocity Prediction Program (VPP) for foiling/non-foiling conditions, a wind tunnel test of sail aerodynamics, a towing tank test of hull hydrodynamics and a large number of numerical predictions of foil characteristics. An optimum foil configuration is developed and towing tank tested with satisfactory results. The final proof of the concept is a successful on the water test with stable foiling at a speed of 12 knots.

Ground granulated iron silicate slag as supplementary cementitious material: Effect of prolonged grinding and granulation temperature
- 2023
-
Ingår i: Cleaner Materials. - : Elsevier. - 2772-3976. ; 10
-
Tidskriftsartikel (refereegranskat)abstract
- The metallurgical and cement industries contribute significantly to anthropogenic carbon dioxide emissions. Utilizing oxidic by-products from the metallurgical industry as supplementary cementitious materials (SCMs) can improve resource efficiency and reduce emissions from cement production. Iron silicate copper slags have been studied as SCMs, but mainly in systems where Portland cement is used as an activator. There is limited research on the inherent reactivity of the slag under changing processing conditions. The present study offers insight into the effect of granulation temperature and grinding on the inherent reactivity of an industrially produced iron silicate copper slag. The results showed that granulation temperature had an insignificant effect on reactivity, while grinding generated substantial improvements. The latter effect was concluded to stem from the increased specific surface area, increased number of sites for nucleation and growth of hydrates, and changes in the inherent reactivity owing to structural changes induced by the grinding.

- Aims: Methods for prediction of the peak of the influenza from early observations are suggested. These predictions can be used for planning purposes. Methods: In this study, new robust methods are described and applied to weekly Swedish data on influenza-like illness (ILI) and weekly laboratory diagnoses of influenza (LDI). Both simple and advanced rules for how to predict the time and height of the peak of LDI are suggested. The predictions are made using covariates calculated from data in early LDI reports. The simple rules are based on the observed LDI values, while the advanced ones are based on smoothing by unimodal regression. The suggested predictors were evaluated by cross-validation and by application to the observed seasons. Results: The relationship between ILI and LDI was investigated, and it was found that the ILI variable is not a good proxy for the LDI variable. The advanced prediction rule regarding the time of the peak of LDI had a median error of 0.9 weeks, and the advanced prediction rule for the height of the peak had a median deviation of 28%. Conclusions: The statistical methods for predictions have practical usefulness.

- Marine energy technologies can contribute to meeting sustainability challenges, but they are still immature and dependent on public support. This paper employs the Technological Innovation Systems (TIS) framework to analyze the development and diffusion of Swedish marine energy up until 2014. While there were promising device developers, relevant industrial capabilities, and world-class research, the system suffered from weaknesses in several important innovation processes. Finally, the analysis identifies the lack of informed political direction as a critical blocking factor and highlights its connection to domestic market potential. © 2016 Elsevier Ltd

A matter of time: Bateman's principles and mating success as count and duration across social strata in contemporary Finland
- 2023
-

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Bateman's principles heavily influence the understanding of human reproductive behaviour. Yet, few rigorous studies on Bateman's principles in contemporary industrialized populations exist. Most studies use small samples, exclude non-marital unions, and disregard recent insights on within-population heterogeneity in mating strategies. We assess mating success and reproductive success using population-wide Finnish register data on marital and non-marital cohabitations and fertility. We examine variability across social strata in the Bateman principles and analyse the mate count, the cumulated duration with a mate, and the association with reproductive success. Results support Bateman's first and second principles. Regarding Bateman's third principle, the number of mates is more positively associated with reproductive success for men than women, but this association is driven by ever having a mate. Having more than one mate is on average associated with lower reproductive success. However, for men in the lowest income quartile, having more than one mate positively predicts reproductive success. Longer union duration is associated with higher reproductive success, and more so for men. We note that sex differences in the relationship between mating success and reproductive success differ by social strata, and argue that mate duration may be an important component of mating success alongside mate count.

A Novel Macro Perspective on Family Dynamics: The Contribution of Partnership Contexts of Births to Cohort Fertility Rates
- 2023

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Partnering behavior is central to understanding fertility. Influential concepts, including singlehood, serial monogamy, and multiple-partner fertility, are frequently used to analyze partnering and childbearing dynamics. These concepts are evoked to understand individual and population-level patterns but are mainly analyzed at the individual level. We propose a measure for gauging the interplay between partnerships and childbearing at the population level, namely cohort fertility rates (CFR) as the sum of births under various partnership contexts. Surprisingly, demographers rarely measure and do not have a clear picture of the extent to which childbearing in different partnership contexts contributes to completed fertility. We analyze Finnish register data to decompose CFR into births across union status, union order, and reproductive partner order. Contrary to the discourse of partnering in the Nordics, births within first unions to first reproductive partners account for about two-thirds of CFR. Births in higher-order unions to first reproductive partners account for one-fifth. Single births and births with higher-order reproductive partners have a modest impact. This ranking holds across sex and educational level. We argue that the proposed measures offer a novel appraisal of population-level implications of partnerships and childbearing dynamics and provide an opportunity to understand cross-country variation in fertility patterns.

Alternativ television : former av kritik i konstnärlig TV-produktion
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation analyses social critique, communication critique and aestheticalcritique in television produced by artists. Theoretically it draws on researchon alternative media, TV studies, especially genre analysis and narratology,and media aesthetics. It conducts a text-production study of three examplesof alternative television from the period 2004-2008: ContemporaryArt Center TV (CAC TV): A show produced by the CAC in Vilnius, Lithuaniaand aired on a commercial TV-channel; Good TV who aired video art ona local public access channel in Stockholm, Sweden; and Candyland TV, apirate transmission from an art gallery in central Stockholm.Empirically it builds on TV-texts, web sites and documents, as well asinterviews with participants. Through a study of form and stylistics, relationto conventional genres and modes of narration, it engages in a discussionabout the features of a critical, alternative media text.The study shows how these televisions work in a tradition of alternativetelevision and connects them to tactics and aesthetical forms as found inhistorical examples, but also how this type of formalist media critiquemight inform an understanding of alternative media. From the analysis ofrelations between social and formalist aspects of alternative television, adistinction between alternative as ”alternative worldview” and as ”alternativeexpressions” is suggested, a distinction that contributes to the developmentof theory in the study of alternative media.

Attention bias and sensitization in chemical sensitivity.
- 2009

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: We investigated whether persons with self-reported chemical sensitivity (CS) have an attention bias and enhanced sensitization to chemical exposure. METHODS: Chemosomatosensory, olfactory, and auditory event-related potentials (ERPs) were recorded from 21 CS subjects and 17 controls in attend and ignore conditions. Reaction times (RTs) and magnitude estimations of perceived intensity were collected in the attend condition. ERPs were averaged over attention conditions and during the first/second part of the testing. RESULTS: ERP patterns indicated that CS subjects did not habituate to the same extent as the controls and had difficulties ignoring the chemical exposure. CS subjects had faster overall RT, and the perceived intensities for the chemosomatosensory stimuli did not decrease with time in the CS group, which was the case for the controls. CONCLUSIONS: These results indicating attention bias and enhanced sensitization in CS suggest alterations in central, cognitive responses to chemical exposure.

Autism, new media and the transformation of "the social"
- 2017
-
Konferensbidrag (refereegranskat)abstract
- People with Asperger Syndrome and high function autism generally suffers from impaired social skills and a strong need for a private space for oneself. In diagnostic classifications of mental illnesses social awkwardness and a strong desire for solitude are viewed as symptoms of mental disorder and as deviances from an imagined normality.Based on interviews with autistic people and analysis of social interaction between them on a social media platform the aim of this paper is to investigate how new social media transform their situation in various ways. New social media, with its culture of connectivity, reshape how they relate to others and themselves and transform vulnerabilities that are always at play in encounters between human beings. At play are also changing borders between the public and the private as well as the questioning of communicative ideals based on face-to-face encounters.More specifically we focus on how new social media transforms: 1) vulnerabilities between people in social interaction as well as the “interaction order” that regulates this interaction; 2) what it means to be a social being – and consequently to be involuntary lonely or seeking solitude.

Brain responses to olfactory and trigeminal exposure in idiopathic environmental illness (IEI) attributed to smells : An fMRI study
- 2014
-
Ingår i: Journal of Psychosomatic Research. - : Elsevier. - 0022-3999 .- 1879-1360. ; 77:5, s. 401-408
-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Idiopathic environmental intolerance (IEI) to smells is a prevalent medically unexplained illness. Sufferers attribute severe symptoms to low doses of non-toxic chemicals. Despite the label, IEI is not characterized by acute chemical senses. Theoretical models suggest that sensitized responses in the limbic system of the brain constitute an important mechanism behind the symptoms. The aim was to investigate whether and how brain reactions to low-levels of olfactory and trigeminal stimuli differ in individuals with and without IEI. METHODS: Brain responses to intranasally delivered isoamyl acetate and carbon dioxide were assessed in 25 women with IEI and 26 non-ill controls using functional magnetic resonance imaging. RESULTS: The IEI group had higher blood-oxygenated-level-dependent (BOLD) signal than controls in the thalamus and a number of, mainly, parietal areas, and lower BOLD signal in the superior frontal gyrus. The IEI group did not rate the exposures as more intense than the control group did, and there were no BOLD signal differences between groups in the piriform cortex or olfactory regions of the orbitofrontal cortex. CONCLUSIONS: The IEI reactions were not characterized by hyper-responsiveness in sensory areas. The results can be interpreted as a limbic hyperreactivity and speculatively as an inability to inhibit salient extemal stimuli.

Chemical Intolerance Is Associated With Altered Response Bias, not Greater Sensory Sensitivity
- 2020
-
Ingår i: i-Perception. - : Sage Publications. - 2041-6695. ; 11:6
-
Tidskriftsartikel (refereegranskat)abstract
- Chemical intolerance is a surprisingly prevalent condition or affliction characterized by adverse reactions to low levels of chemical, often odorous stimulation. Sufferers often assume that their plight is due to an uncommon sensory acuteness, yet studies repeatedly fail to reveal altered detection thresholds. Here, we investigated whether self-reported chemical intolerance is associated with altered sensory sensitivity or response bias. The sensory acuity (sensitivity; A) and sensory decision rule (criterion; B) to n-butanol was assessed using the method of constant stimuli in 82 participants with different degrees of chemical intolerance (low to high). Higher self-reported chemical intolerance was associated with a lower criterion, but not with sensitivity.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate whether there are differences between women and men in how chemosensory stimuli are processed. Event-related potentials from 36 participants (18 men) showed that women had larger P3 amplitudes when attending, but not when ignoring CO 2 but not for n-butanol, compared with men. The main finding was that women and men differ in cognitive measures of chemosensory processing.

- Purpose: Multiple chemical sensitivity (MCS) is a prevalent medically unexplained symptom characterized by symptom reactions to everyday chemical exposure below hygienic thresholds. The aim of this study was to investigate the expressions of hyper-reactivity in MCS during whole-body exposure to low concentrations of the odorant n-butanol.Methods: We exposed 18 participants with MCS and 18 non-ill controls to a low concentration of the odorantn-butanol using an exposure chamber. The first 10 min constituted blank exposure, after which then-butanol concentration increased and reached a plateau at 11.5 mg/m3.Results: MCS participants, compared with controls, reported greater perceived odor intensities, more unpleasantness to the exposure and increasing symptoms over time. MCS participants also expressed higher pulse rate and lower pulse rate variability than controls did. No group differences were found for breathing rate or tonic electrodermal activity responses.Conclusions: We conclude that MCS sufferers differ from healthy controls in terms of autonomic responses, symptoms and chemosensory perception during chemical exposure.

Child participation in the design of media and information literacy interventions : A scoping review and thematic analysis
- 2021
-
Ingår i: Journal of Media Literacy Education. - Kingston : National Association for Media Literacy Education. - 2167-8715. ; 13:1, s. 14-27
-
Tidskriftsartikel (refereegranskat)abstract
- The article presents findings from a review of scientific articles about media and information literacy interventions targeted at children and adolescents. More specifically, the review centers on the quantity and quality of child participation in the design of such interventions. The findings indicate that designs with high levels of child participation constitute a minority in the sample. Most of them aim at “behavior-relevant” outcomes, e.g., reduce smoking or obesity. Interventions aimed at “media-relevant” outcomes, e.g., helping children to become competent media users, seem less widespread. Based on these findings, we argue that top-down initiatives to the promotion of media and information literacy among children and adolescents run the risk of becoming irrelevant to the target group, and that child participation in the design of such interventions should be seen as an end in itself, at least if we subscribe to the idea of children’s rights in the digital age.

Disaster Tourists, Smartphone Bystanders, Mediated Witnesses or Citizen Journalists? Bystander Theories and Mobile Media Practices at Accident Sites
- 2016
-
Ingår i: ECREA 2016 Abstact Book. - Prague : Czech-In. - 9788090665507 ; , s. 176-176
-
Konferensbidrag (refereegranskat)abstract
- This paper addresses the phenomenon of bystanders who use their smartphones to film or take photographs at accident scenes, instead of offering their help to people in need or to assist medical units. This phenomenon has been extensively discussed in Swedish news media in recent years, since it has been described as a growing problem for rescue workers, like paramedics, police and fire fighters.Some of the early literature in social psychology explained bystander inaction by indifference, but in the late 1960’s, the American researchers Darley and Latane showed that bystander inaction could be explained as an effect of the size of the bystander crowd. With an increase of the number of the bystanders, the chances of their involvement to help decreased.The past decade has seen an growing scholarly interest in “media witnessing”, both in terms of witnessing from a distance through mass media, as discussed by Peters, and “citizen camera-witnessing”, a term popularised by the works of Allan and Andrén-Papadopoulos. This literature recognizes the complexity of concepts such as active/passive and proximity/distance when it comes to media witnessing in the digital era.Drawn from previous research and theories, the aim of this paper is to discuss how bystander theory can be further developed to include the action of mobile media practices at scenes like accidents. From this perspective, the paper also draws attention to what could be a part of a mediated cultural trauma found in contemporary society and thereby connects to the theme of the conference.The paper identifies four categories in the literature that are relevant for further research into the phenomenon and to be connected to the framework of bystander theories. These categories are: “disaster tourism”, “citizen (photo) journalism”, “media witnessing”, and “digital media ethics”.The paper ends with a discussion about possible theoretical approaches to further empirical studies on contemporary bystander phenomena.

Do the formative aspects of education really matter for educational assortative mating? Cues from a natural experiment
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Individuals tend to partner with people of a similar educational level as themselves. According to the matching hypothesis, exposure to education leads to similarity in taste and cultural cognitive schemas, causing educationally similar partners to form unions. In this study, I ask if such formative content of education matters for educational homogamy, net of other forces. Evaluating this claim is often difficult because educational level also beget human resources and because marriage markets are structured by educational level - aspects which also lead to educational homogamy. I approach this issue using a semi-experimental design that tentatively holds constant marriage markets and human capital related to education. Using a national reform, I compare the educational assortative mating of upper secondary vocational students who studied under a theoretical curriculum to that of vocational students not exposed to a theoretical curriculum. The reform provides variability in formative education. Yet, it induces no variation in competitive human capital and marriage markets, as students obtain comparable human capital within the same standard upper secondary track. Therefore, effects may be attributed to matching on formative content of the added theoretical curriculum. Before and after adjusting for selection, I find no effect of an added theoretical curriculum on partnering. The results are discussed in terms of the ambiguity of formative education as an explanation for educational assortative mating.

Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses
- 2018
-
Ingår i: Chemical Senses. - : Oxford University Press (OUP). - 0379-864X .- 1464-3553. ; 43:2, s. 129-134
-
Tidskriftsartikel (refereegranskat)abstract
- A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.

Efficient nonlinear reduced order modeling for dynamic analysis of flat structures
- 2023
-
Ingår i: Mechanical Systems and Signal Processing. - : Elsevier BV. - 0888-3270. ; 191
-
Tidskriftsartikel (refereegranskat)abstract
- In the present paper, strategies for reduced order modeling of geometrically nonlinear finite element models are investigated. Simulation-free, non-intrusive approaches are considered, which do not require access to the source code of a finite element program (e.g., proprietary knowledge). Our study focus on but is not restricted to flat structures. Reduction bases are generated using bending modes and the associated modal derivatives, which span the additional subspace needed for an adequate approximation of the geometrically nonlinear response. Moreover, the reduced nonlinear restoring forces are expressed as third order polynomials in modal coordinates. Consequently, the reduced systems can be effectively solved using time-integration schemes involving only the reduced coordinates. A bottleneck in the non-intrusive methods is typically the computational effort for precomputing the polynomial coefficients and generating the reduction basis. In this regard, we demonstrate that modal derivatives have several useful properties. In particular, the modal derivatives essentially provide all the information needed for generating the polynomial coefficients for the in-plane coordinates. For condensed systems, which ignores the inertia of the in-plane modes, we show that the modal derivatives can be used effectively for recovering the in-plane displacements. Based on these findings, we propose a methodology for generating reduced order models of geometrically nonlinear flat structures in a computationally efficient manner. Moreover, we demonstrate that the concepts extend also to curved structures. The modeling techniques are validated by means of numerical examples of solid beam models and continuously supported shell models. The computational efficiency of the proposed methodology is evaluated based on the number of static evaluations needed for identifying the polynomial coefficients, as compared to the state-of-the-art methods. Furthermore, strategies for efficient time integration are discussed and evaluated.

Essays on Family Dynamics : Partnering, Fertility and Divorce in Sweden
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Diversity in household and family structures poses interesting questions for scientific inquiry. What accounts for patterns of reproduction, partnering, household formation and household dissolution? This dissertation investigates facets of this question in the context of modern Sweden from a longitudinal and individual level perspective. It consists of three empirical studies using data from administrative registers and panel survey data. The first study begins with noting a rapid expansion in online education and analyzes whether this development leads to higher fertility in student populations. The second study asks whether individuals’ predispositions towards divorce change after exposure to the experience of parenthood, union formation and union dissolution. The third study builds on the literature on assortative mating and investigates what drives underlying preferences for this behavior.

From closet-fill to toxic sublime : The aesthetics of e-waste
- 2019
-
Ingår i: 18th Annual STS Conference Graz 2019. ; , s. 58-59
-
Konferensbidrag (refereegranskat)abstract
- Electronic waste (e-waste) has a peculiar relation to space. It is well-documented how a large part of discarded electronic devices still remain in people’s homes, instead of reaching the recycling centres. This is especially true with digital media and communication technologies such as computers and mobile phones (ironically the devices with the shortest life cycles). This phenomenon has been described by the term “closet-fill” (as opposed to land-fill). However, representations of electronic waste in public discourse such as news reports, seldom focus on this aspect. Instead, they tend to portray e-waste dumping sites as strange, almost alien spaces. Sublime imagery invites the viewer to a contemplation over Western consumerism in a fashion recognizable from visual arts. Consequently, imagery of electronic waste has also become an object of aesthetic value in the works of renowned visual artists such as Pieter Hugo and David LaChapelle, who have gained recognition because of this inclusion of imagery of e-waste in their photographic art. The aim of this paper is to address these aesthetic qualities of electronic waste. The purpose is to contribute to the expanding literature on media materialities and waste with a conceptual understanding of manifestations of electronic waste in popular discourse. The paper draws on theories on media aesthetics, environmental communication and waste management to build an analytic framework that explores the benefits and limitations of presenting electronic waste as an aesthetic object. Empirically it engages in analyses of visual representations of electronic waste. The paper addresses the tension between aesthetic contemplation/appreciation, and critical information. It could be argued that if e-waste is to be presented and understood as an urgent topic, there might be a problem if it is portrayed as something strange, exotic or even beautiful. The concept ”toxic sublime” has been used in analyses of visual representations of pollution, and Peeples (2011: 383) argues that this construction of the toxic as sublime comes with a risk: “It may predispose people to look for toxins in the extraordinary, as opposed to on the shelves of their garages”. It could be argued that e-waste faces a similar problem. The focus on the sublime strangeness of e-waste “dumping sites” is an ineffective way of creating proximity and urgency to the e-waste problem, something that takes place somewhere else than in our homes. LeBel (2015) argues that e-waste aesthetics fails to address the temporal dimension of waste (e.g. planned obsolescence, toxicity). This paper intends to add to that argument by highlighting the tension between the closet-fill and the toxic sublime

From reality-TV to rurality-TV : Exploring the genre of idealised rural lifestyles in the Nordic public service television
- 2024
-
Ingår i: The Future of the Nordic Media Model. - Göteborg : Nordicom. ; , s. 277-298
-
Bokkapitel (refereegranskat)abstract
- This chapter introduces rurality-TV as a genre, and we discuss how public service media, through this genre, contributes to symbolically resolving tensions between the rural and the urban, and we address processes of mobility and urbanisation in the Nordics. Three popular reality-TV programmes depicting rural life are analysed: Bonderøven [loosely translated as The Hillbilly], later known as Frank & Kastaniegaarden (DR), Hjälp vi har köpt en bondgård! [Help we have bought a farm!] (SVT), and Oppfinneren [The Inventor] (NRK). These are approached through three questions: What constitutes public service rurality-TV as a genre in terms of form and content? What values are negotiated in the programmes? How can we understand rurality-TV in the context of public service broadcasting in the media welfare state?

Gender, family life course and attitudes towards divorce in Sweden
- 2016
-
Ingår i: Acta Sociologica. - : SAGE Publications. - 0001-6993 .- 1502-3869. ; 59:1, s. 51-67

Tidskriftsartikel (refereegranskat)abstract
- The present study investigates the impact of union formation, parenthood and union dissolution on Swedes’ attitudes toward divorce. The results, based on fixed-effects models of longitudinal data from the Young Adult Panel Study (YAPS), suggest a prevalent, albeit small, influence of family life-course events on attitudes toward divorce in Sweden. Attitudes toward divorce are studied using two survey statements: ‘It is too easy to get divorced in today’s Sweden’ (item A) and ‘Parents should stay together for the sake of their children’ (item B). For both items, union dissolution from parental relationships is associated with a decrease in intolerance toward divorce, but only for women. For men, but not for women, parental union formation increases intolerance toward divorce as measured by item B. The results are discussed in relation to the literature on gendered family life-course experiences.

Highlighting the large variation in perceived properties of odors over time
- 2017
-
Ingår i: Chemical Senses. - 0379-864X .- 1464-3553. ; 42:2, s. E26-
-
Tidskriftsartikel (refereegranskat)abstract
- Individuals differ considerably when rating the perceived properties of odors, especially over time. A second glance at previously published data-sets from our laboratory revealed that the same invariant exposure often produced both floor and roof effects. An odor that at the end of the exposure ses-sion was regarded as non-existent by one participant, could border the “absoulte maximum” rating category in another. We provide re-analyses from four exposure studies where we illustrate the perceptual variability over time, and outcomes associated with such ratings. We note that high, compared with low ratings of odor intensity over time is associated with ratings of unpleasantness and symptoms, but also with everyday distress, cognitive performance, autonomous nerv-ous system activity and deviating responses in the so-called pain or saliency matrix of the brain. We bring an open ques-tion to ECRO regarding how this considerable variability should be interpreted, and what the consequenced are for research and for setting exposure limits.
