- Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established a common protocol to measure plant phenology in tundra study areas across the globe. Today, this valuable collec-tion of phenology measurements depicts the responses of plants at the colder extremes of our planet to experimental and ambient changes in temperature over the past decades. The database contains 150 434 phenology observations of 278 plant species taken at 28 study areas for periods of 1–26 years. Here we describe the full data set to increase the visibility and use of these data in global analyses and to invite phenology data contributions from underrepresented tundra locations. Portions of this tundra phenology database have been used in three recent syntheses, some data sets are expanded, others are from entirely new study areas, and the entirety of these data are now available at the Polar Data Catalogue (https://doi.org/10.21963/13215).

- The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one high-energy neutrino was associated with a tidal disruption event (TDE). Here we present AT2019fdr, an exceptionally luminous TDE candidate, coincident with another high-energy neutrino. Our observations, including a bright dust echo and soft late-time x-ray emission, further support a TDE origin of this flare. The probability of finding two such bright events by chance is just 0.034%. We evaluate several models for neutrino production and show that AT2019fdr is capable of producing the observed high-energy neutrino, reinforcing the case for TDEs as neutrino sources.

- Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1-km2 resolution for 0–5 and 5–15 cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1-km2 pixels (summarized from 8519 unique temperature sensors) across all the world's major terrestrial biomes, and coarse-grained air temperature estimates from ERA5-Land (an atmospheric reanalysis by the European Centre for Medium-Range Weather Forecasts). We show that mean annual soil temperature differs markedly from the corresponding gridded air temperature, by up to 10°C (mean = 3.0 ± 2.1°C), with substantial variation across biomes and seasons. Over the year, soils in cold and/or dry biomes are substantially warmer (+3.6 ± 2.3°C) than gridded air temperature, whereas soils in warm and humid environments are on average slightly cooler (−0.7 ± 2.3°C). The observed substantial and biome-specific offsets emphasize that the projected impacts of climate and climate change on near-surface biodiversity and ecosystem functioning are inaccurately assessed when air rather than soil temperature is used, especially in cold environments. The global soil-related bioclimatic variables provided here are an important step forward for any application in ecology and related disciplines. Nevertheless, we highlight the need to fill remaining geographic gaps by collecting more in situ measurements of microclimate conditions to further enhance the spatiotemporal resolution of global soil temperature products for ecological applications.

- Background Respiratory failure worsens the outcome of acute pancreatitis (AP) and underlying factors might be early detectable. Aims To evaluate the prevalence and prognostic relevance of early pleuropulmonary pathologies and pre-existing chronic lung diseases (CLD) in AP patients. Methods Multicentre retrospective cohort study. Caudal sections of the thorax derived from abdominal contrast enhanced computed tomography (CECT) performed in the early phase of AP were assessed. Independent predictors of severe AP were identified by binary logistic regression analysis. A one-year survival analysis using Kaplan-Meier curves and log rank test was performed. Results 358 patients were analysed, finding pleuropulmonary pathologies in 81%. CECTs were performed with a median of 2 days (IQR 1–3) after admission. Multivariable analysis identified moderate to severe or bilateral pleural effusions (PEs) (OR = 4.16, 95%CI 2.05–8.45, p<0.001) and pre-existing CLD (OR = 2.93, 95%CI 1.17–7.32, p = 0.022) as independent predictors of severe AP. Log rank test showed a significantly worse one-year survival in patients with bilateral compared to unilateral PEs in a subgroup. Conclusions Increasing awareness of the prognostic impact of large and bilateral PEs and pre-existing CLD could facilitate the identification of patients at high risk for severe AP in the early phase and thus improve their prognosis.

Tidskriftsartikel (refereegranskat)abstract
- Background: Adolescent major depressive disorder (MDD) is highly prevalent and associated with lifelong adversity. Evidence-based treatments exist, but accessible treatment alternatives are needed. We aimed to compare internet-based psychodynamictherapy (IPDT) with an established evidence-based treatment (internet-based cognitive behavioural therapy [ICBT]) for the treatment of adolescents with depression.Methods: In this randomised, clinical trial, we tested whether IPDT was non-inferior to ICBT in the treatment of adolescent MDD. Eligible participants were 15–19 years old, presenting with a primary diagnosis of MDD according to DSM-5. Participants were recruited nationwide in Sweden through advertisements on social media, as well as contacts with junior and senior high schools, youth associations, social workers, and health-care providers. Adolescents who scored 9 or higher on the Quick Inventory of Depressive Symptomatology for Adolescents (QIDS-A17-SR) in an initial online screening were contacted by telephone for a diagnostic assessment using the Mini International Neuropsychiatric Interview. Participants were randomly assigned to ICBT or IPDT. Both interventions comprised eight self-help modules delivered over 10 weeks on a secure online platform. The primary outcome was change in depression severity measured weekly by the QIDS-A17-SR. Primary analyses were based on an intention-to-treat sample including all participants randomly assigned. A non-inferiority margin of Cohen's d=0·30 was predefined. The study is registered at ISRCTN, ISRCTN12552584.Findings: Between Aug 19, 2019, and Oct 7, 2020, 996 young people completed screening; 516 (52%) were contacted for a diagnostic interview. 272 participants were eligible and randomly assigned to ICBT (n=136) or IPDT (n=136). In the ICBT group, 51 (38%) of 136 participants were classified as remitted, and 54 (40%) of 136 participants were classified as remitted in the IPDT group. Within-group effects were large (ICBT: within-group d=1·75, 95% CI 1·49 to 2·01; IPDT: within-group d=1·93, 1·67 to 2·20; both p<0·0001). No statistically significant treatment difference was found in the intention-to-treat analysis. Non-inferiority for IPDT was shown for the estimated change in depression during treatment (d=–0·18, 90% CI –0·49 to 0·13; p=0·34). All secondary outcomes showed non-significant between-group differences.Interpretation: IPDT was non-inferior to ICBT in terms of change in depression for the treatment of adolescents with MDD. This finding increases the range of accessible and effective treatment alternatives for adolescents with depression.

Towards Digital Environmental Stewardship : the Work of Caring for the Environment in Waste Management

Konferensbidrag (refereegranskat)abstract
- This paper discusses Digital Environmental Stewardship as an analytical framework that can help HCI scholarship to understand, design, and assess sociotechnical interventions concerned with sustainable waste management practices. Drawing on environmental studies, we outline key concepts of environmental stewardship - namely actors, capacity, and motivations - to unpack how different initiatives for handling waste are organised, both through grassroots and top-down interventions, and through varying sociotechnical configurations. We use these dimensions to analyse three different cases of waste management that illustrate how actions of care for the environment are ecologically organised, and what challenges might hinder them beyond -or besides- behavioural motivations. We conclude with a discussion on the orientation to action that the suggested framework provides, and its role in understanding, designing and assessing digital technologies in this domain. We argue that examining how stewardship actions fold into each other helps design sociotechnical interventions for managing waste from within a relational perspective.

Maskulinitetens mening : En fenomenologisk undersökning av den psykoterapeutiska situationen
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)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.

TAROGE-M : radio antenna array on antarctic high mountain for detecting near-horizontal ultra-high energy air showers
- 2022
-
Ingår i: Journal of Cosmology and Astroparticle Physics. - : IOP Publishing. - 1475-7516. ; :11
-
Tidskriftsartikel (refereegranskat)abstract
- The TAROGE-M radio observatory is a self-triggered antenna array on top of the similar to 2700m high Mt. Melbourne in Antarctica, designed to detect impulsive geomagnetic emission from extensive air showers induced by ultra-high energy (UHE) particles beyond 1017 eV, including cosmic rays, Earth-skimming tau neutrinos, and particularly, the "ANITA anomalous events" (AAE) from near and below the horizon. The six AAE discovered by the ANITA experiment have signal features similar to tau neutrinos but that hypothesis is in tension either with the interaction length predicted by Standard Model or with the flux limits set by other experiments. Their origin remains uncertain, requiring more experimental inputs for clarification. The detection concept of TAROGE-M takes advantage of a high altitude with synoptic view toward the horizon as an efficient signal collector, and the radio quietness as well as strong and near vertical geomagnetic field in Antarctica, enhancing the relative radio signal strength. This approach has a low energy threshold, high duty cycle, and is easy to extend for quickly enlarging statistics. Here we report experimental results from the first TAROGEM station deployed in January 2020, corresponding to approximately one month of livetime. The station consists of six receiving antennas operating at 180-450 MHz, and can reconstruct source directions of impulsive events with an angular resolution of similar to 0.3 ffi, calibrated in situ with a drone-borne pulser system. To demonstrate TAROGE-M's ability to detect UHE air showers, a search for cosmic ray signals in 25.3-days of data together with the detection simulation were conducted, resulting in seven identified candidates. The detected events have a mean reconstructed energy of 0.95+0.46 -0.31 EeV and zenith angles ranging from 25 ffi to 82 ffi, with both distributions agreeing with the simulations, indicating an energy threshold at about 0.3 EeV. The estimated cosmic ray flux at that energy is 1.2+0.7 -0.9x10(-16) eV(-1) km(-2) yr(-1) sr(-1), also consistent with results of other experiments. The TAROGE-M sensitivity to AAEs is approximated by the tau neutrino exposure with simulations, which suggests comparable sensitivity as ANITA's at around 1 EeV energy with a few station-years of operation. These first results verified the station design and performance in a polar and high-altitude environment, and are promising for further discovery of tau neutrinos and AAEs after an extension in the near future.
