- Purpose - Many firms use customer co-creation practices with the aim of benefiting from their customers' knowledge, skills and resources. This paper aims to explore co-creation processes which involve users with different background characteristics and motivational drivers.Design/methodology/approach -The study builds on an analysis of data from six teams in which users collaborated with in-house professionals for the development of new service concepts. Observations and open-ended questionnaires provided insights into the teams' development processes. Independent experts rated the generated concepts. The data were analysed using cross-comparison matrices.FindingsThe findings suggest that the co-creation process and outcomes can be influenced by numerous intra-team factors, including relationship and task conflicts, participation style, team bonding, team identity and cohesiveness and intra-team collaboration. Their occurrence and influence seem to be linked with a specific team composition. A conceptual co-creation process model and six propositions are used to describe the complex relationships between team composition, intra-team factors and key innovation outcomes.Research limitations/implications - Research that investigates user involvement in teams needs to consider the complexity of intra-team factors affecting the development process and outcomes. The findings are limited to a specific setting, design task and user sample. Future research should replicate this study in different sectors.Practical implications - Key to customer co-creation is the systematic recruitment of users based on their background characteristics and motivational drivers. For instance, the involvement of users with very specific innovation-related benefit expectations can cause conflict, leading to narrowly focused outcomes. This, however, can be mitigated by the form of facilitation and roles adopted by in-house professionals. Understanding intra-team dynamics can allow the firm to assemble and facilitate customer co-creation so that generated outcomes can align with set innovation targets.Originality/value -This paper provides original insights into the "black box" of the customer co-creation process and the complex relationship between team composition, intra-team factors and key innovation outcomes.

- BackgroundGastric bypass (GBP) surgery is considered a safe and effective treatment for obesity. However, there is uncertainty regarding the impact of preexisting psychiatric comorbidity on GBP complications. We have investigated whether a psychiatric diagnosis before GBP surgery is associated with delayed discharge (the odds of being in the 90th percentile of length of stay) and rate of reoperation in a nationwide Swedish cohort.MethodsPatients undergoing GBP surgery during 2008–2012 were identified and followed up through the National Patient Register and the Prescribed Drug Register. Logistic regression models were fitted to the studied outcomes.ResultsAmong the 22,539 patients identified, a prior diagnosis of bipolar disorder, schizophrenia, depression, neurotic disorders, ADHD (attention deficit hyperactivity disorder), substance use disorder, eating disorder, personality disorder, or self-harm since 1997 (n = 9480) was found to be associated with delayed discharge after GBP surgery (odds ratio [OR] = 1.47, confidence interval [CI] 1.34–1.62), especially in patients with psychiatric hospitalization exceeding 1 week in the 2 years preceding GBP surgery (OR = 2.06, CI 1.30–3.28), compared with those not hospitalized within psychiatry. Likewise, patients with a prior psychiatric diagnosis were more likely to be reoperated within 30 days (OR = 1.25, CI 1.11–1.41), with twice the likelihood OR 2.23 (CI 1.26–3.92) for patients with psychiatric hospitalization of up to a week in the 2 years preceding GBP surgery, compared with patients who had not been hospitalized within psychiatry.ConclusionsA psychiatric diagnosis before GBP surgery was associated with delayed discharge and increased likelihood of reoperation within 30 days. Patients with a prior psychiatric diagnosis may, therefore, need additional attention and support.

Maskulinitetens mening : En fenomenologisk undersökning av den psykoterapeutiska situationen
- 2022

Doktorsavhandling (övrigt vetenskapligt)abstract
- Masculinity is an elusive and ambiguous phenomenon that can manifest itself in many different ways in different contexts. This study focuses on the emergence of masculinity within the psychodynamic psychotherapeutic situation, with a focus on how masculinity is experienced. Both patient and therapist carry notions and experiences of masculinity into the therapy room. In addition, the psychotherapeutic situation, in itself, can evoke notions of gender. Sometimes masculinity can be the focus of the therapy, which previous research to some extent has drawn theoretical attention to, with a focus on certain aspects. However, there is a need for an empirical holistic approach to how masculinity is manifested in psychotherapy.The purpose of the dissertation is to clarify the meaning of masculinity, as it appears in the psychotherapeutic situation. This purpose is answered by empirically describing how masculinity is experienced in psychotherapy from two perspectives – the patient's and the psychotherapist's. The study is based on 27 in-depth interviews which were analyzed using a phenomenological method. The result is presented in the form of two meaning structures; one for the patient's experience of masculinity and another for the psychotherapist's experience. Finally, these two meaning structures are compared, in order to highlight common features and differences.The study shows that the patient's experience of masculinity is primarily rooted in the patient’s lived, first-person perspective, while the therapist's experience to a greater extent is constituted by a second- and third-person perspective. Both patient and therapist symbolize and conceptualize masculinity through different levels, where they share a bodily and a ”taken-for-granted” dimension. Their conceptualizations differ in that the therapist also has access to a theoretically informed perspective. Both patient and therapist constitute masculinity in a normative way; for the patient, the normative dimension is perceived in terms of ego-syntonic and ego-dystonic masculinity ideals and norms, while the therapist defines masculinity as either a positive or a negative phenomenon.A distinctive aspect of the result is, that masculinity can appear in terms of suffering for the patient or in terms of masculinity issues for the therapist. The masculinity suffering/masculinity issues can be associated with a polarized or immature form of masculinity, which – in the context of therapy – can undergo changes until appearing in a non-polarized, mature way. Another type of masculinity suffering, is when the patient does not feel in contact with masculinity. The result describes a changed masculinity experience in terms of a changed masculinity narrative, which can undergo three different elements; the prefigurative ground, the configurative processing, and the refigurative gestalt of masculinity. The study also sheds light on how the patient and therapist relate to one another in the light of a changed masculinity narrative.The comparative analysis shows that masculinity can be attributed with divergent meanings within the psychotherapeutic situation, and also includes a developmental, therapeutic and normative dimension. One conclusion is that masculinity has two sources of meaning; one lived and one theoretical origin. The lived perspective is linked to the life world, while the theoretical perspective has the potential to elaborate and broaden the life world experience of masculinity.

- There exists a conspicuous gap of knowledge about the organization of life at mesoscopic levels. Ultra-fast coherent diffractive imaging with X-ray free-electron lasers can probe structures at the relevant length scales and may reach sub-nanometer resolution on micron-sized living cells. Here we show that we can introduce a beam of aerosolised cyanobacteria into the focus of the Linac Coherent Light Source and record diffraction patterns from individual living cells at very low noise levels and at high hit ratios. We obtain two-dimensional projection images directly from the diffraction patterns, and present the results as synthetic X-ray Nomarski images calculated from the complex-valued reconstructions. We further demonstrate that it is possible to record diffraction data to nanometer resolution on live cells with X-ray lasers. Extension to sub-nanometer resolution is within reach, although improvements in pulse parameters and X-ray area detectors will be necessary to unlock this potential.

- Structural studies on living cells by conventional methods are limited to low resolution because radiation damage kills cells long before the necessary dose for high resolution can be delivered. X-ray free-electron lasers circumvent this problem by outrunning key damage processes with an ultra-short and extremely bright coherent X-ray pulse. Diffraction-before-destruction experiments provide high-resolution data from cells that are alive when the femtosecond X-ray pulse traverses the sample. This paper presents two data sets from micron-sized cyanobacteria obtained at the Linac Coherent Light Source, containing a total of 199,000 diffraction patterns. Utilizing this type of diffraction data will require the development of new analysis methods and algorithms for studying structure and structural variability in large populations of cells and to create abstract models. Such studies will allow us to understand living cells and populations of cells in new ways. New X-ray lasers, like the European XFEL, will produce billions of pulses per day, and could open new areas in structural sciences.

- Cyclopropylfentanyl is a fentanyl analog implicated in 78 deaths in Europe and over 100 deaths in the United States, but toxicological information including metabolism data about this drug is scarce. The aim of this study was to provide the exact structure of abundant and unique metabolites of cyclopropylfentanyl along with synthesis routes. In this study, metabolites were identified in 13 post-mortem urine samples using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Samples were analyzed with and without enzymatic hydrolysis, and seven potential metabolites were synthesized in-house to provide the identity of major metabolites. Cyclopropylfentanyl was detected in all samples, and the most abundant metabolite was norcyclopropylfentanyl (M1) that was detected in 12 out of 13 samples. Reference materials were synthesized (synthesis routes provided) to identify the exact structure of the major metabolites 4-hydroxyphenethyl cyclopropylfentanyl (M8), 3,4-dihydroxyphenethyl cyclopropylfentanyl (M5) and 4-hydroxy-3-methoxyphenethyl cyclopropylfentanyl (M9). These metabolites are suitable urinary markers of cyclopropylfentanyl intake as they are unique and detected in a majority of hydrolyzed urine samples. Minor metabolites included two quinone metabolites (M6 and M7), not previously reported for fentanyl analogs. Interestingly, with the exception of norcyclopropylfentanyl (M1), the metabolites appeared to be between 40% and 90% conjugated in urine. In total, 11 metabolites of cyclopropylfentanyl were identified, including most metabolites previously reported after hepatocyte incubation.

Tidskriftsartikel (refereegranskat)abstract
- The genetic background of childhood body mass index (BMI), and the extent to which the well-known associations of childhood BMI with adult diseases are explained by shared genetic factors, are largely unknown. We performed a genome-wide association study meta-analysis of BMI in 61,111 children aged between 2 and 10 years. Twenty-five independent loci reached genome-wide significance in the combined discovery and replication analyses. Two of these, located near NEDD4L and SLC45A3, have not previously been reported in relation to either childhood or adult BMI. Positive genetic correlations of childhood BMI with birth weight and adult BMI, waist-to-hip ratio, diastolic blood pressure and type 2 diabetes were detected (Rg ranging from 0.11 to 0.76, P-values <0.002). A negative genetic correlation of childhood BMI with age at menarche was observed. Our results suggest that the biological processes underlying childhood BMI largely, but not completely, overlap with those underlying adult BMI. The well-known observational associations of BMI in childhood with cardio-metabolic diseases in adulthood may reflect partial genetic overlap, but in light of previous evidence, it is also likely that they are explained through phenotypic continuity of BMI from childhood into adulthood.

- The paper concentrates on the study of Mo-V-Te-Nb oxide mixtures by electron microscopy combined with catalytic investigation of these materials in the partial oxidation of propane. Surface texturing of catalyst particles composed of two phases referred to in the literature as M1 and M2 is revealed by high-resolution transmission electron microscopy of high performing catalysts. The chemical composition of the catalyst surface is modified by treatment in water to obtain a significant increment in yield of acrylic acid. A chemical realization of the site isolation concept recurring on a supramolecular arrangement of catalyst and reactant rather than on atomic site isolation is suggested. A complex Mo-V-Te-Nb-O (x) precursor phase carries nanoparticles made from a network of oxoclusters active as catalyst for the conversion of propane to acrylic acid. The designed synthesis of the multi-element oxide bulk and of the surface structure with a different composition than the precursor phase improved the performance by a factor of 4.
