- Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

Innovation and job quality in the aeronautic industry : Results from qualitative case studies
- 2017
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The paper focuses on the interactions between innovations (of all kinds) and job quality (in a wide sense, covering work and employment conditions, including job status, compensation, training and career opportunities) in the aeronautic industry. It draws on empirical evidence – industry survey and company case studies – from France, Sweden and the UK. Aeronautics has introduced important innovations in the past decade. For example, computer assisted devices (from computer aided engineering and design, Model Based Definition (MBD), i.e. the use of 3D drawings, to computer numeric control machines) have impacted the work of both engineers, technicians and operators. The new generation of process innovations (i.e. digitalization) include, among others, the introduction of cobots and robots, and virtual augmented reality devices. Aeronautics is indeed a front runner of the “factory of the future” or “industry 4.0”, which may have important consequences in terms of both job quantity and quality – notably in terms of education requirements, competence development, and individual task discretion/autonomy. Organisational innovations have also played an important role, such as the implementation of lean manufacturing and its derivatives, introduced more recently than in the automotive industry, with some specificities. Increasing pressure on all the segments of the supply chain has been witnessed in many firms and their subcontractors, in connection with some of the technical devices mentioned previously, and in a context of increasing competition, and in some cases to important changes in the governance of firms. But the reverse causality – i.e. from JQ to innovation – is also a key issue. Some firms are innovating by introducing new forms of organisations to improve some dimensions of job quality as a mean to foster the innovation capacity of the firm “from the bottom up”, with experiments such as “liberated company”. As in other industries, some big companies are trying to emulate the “start-up spirit”.

Tidskriftsartikel (refereegranskat)abstract
- We employed gene array technology to investigate the effects of alpha 1-antichymotrypsin (ACT), soluble or fibrillar Alzheimer's peptide (A beta(1-42)) alone and the combination of ACT/A beta(1-42) on human astrocytes. Using a 1.2-fold change as significance threshold, 398 astrocyte genes showed altered expression in response to these treatments compared to controls. Of the 276 genes affected by the ACT/soluble A beta(1-42) combination, 195 (70.6%) were suppressed. The ACT/fibrillar A beta(1-42) combination affected expression of 64 genes of which 58 (90.5%) were up-regulated. The most prominent gene expression changes in response to the ACT/soluble A beta(1-42), were the down-regulation of at least 60 genes involved in transcription, signal transduction, apoptosis and neurogenesis. The ACT/fibril A beta(1-42) increased the expression of genes involved in transcription regulation and signal transduction. Surprisingly, gene expression of astrocytes exposed to soluble or fibrillar A beta(1-42) alone was largely unaffected. Thus, the molecular forms generated by the combination of ACT/A beta(1-42) alter expression of astrocyte genes more profoundly in breadth and magnitude than soluble or fibrillar A beta(1-42) alone, suggesting that pathogenic effects of A beta(1-42) may occur as a consequence of its association with other proteins.

- BACKGROUND: Canine osteosarcoma is clinically nearly identical to the human disease, but is common and highly heritable, making genetic dissection feasible.RESULTS: Through genome-wide association analyses in three breeds (greyhounds, Rottweilers, and Irish wolfhounds), we identify 33 inherited risk loci explaining 55% to 85% of phenotype variance in each breed. The greyhound locus exhibiting the strongest association, located 150 kilobases upstream of the genes CDKN2A/B, is also the most rearranged locus in canine osteosarcoma tumors. The top germline candidate variant is found at a >90% frequency in Rottweilers and Irish wolfhounds, and alters an evolutionarily constrained element that we show has strong enhancer activity in human osteosarcoma cells. In all three breeds, osteosarcoma-associated loci and regions of reduced heterozygosity are enriched for genes in pathways connected to bone differentiation and growth. Several pathways, including one of genes regulated by miR124, are also enriched for somatic copy-number changes in tumors.CONCLUSIONS: Mapping a complex cancer in multiple dog breeds reveals a polygenic spectrum of germline risk factors pointing to specific pathways as drivers of disease.

Innovations on a shoestring: Consequences for job quality of public service innovations in health and social care
- 2020
-
Ingår i: European Journal of Workplace Innovation. - 2387-4570. ; 5:2, s. 4-30
-
Tidskriftsartikel (refereegranskat)abstract
- The article examines the innovation-job quality-employment nexus in social and health care in the United Kingdom and Sweden, respectively. Through seven case studies carried out with a common methodological and analytical framework in the two countries, it shows how the constraining factors of fiscal strictures derived from budgetary regimes and chronic labor shortages have two key consequences for innovation. The first is that in the absence of room for maneuver with regard to extrinsic job quality, intrinsic job quality becomes the primary innovation arena. Here the activation of feelings and ideologies of empathy towards patients and clients and occupational/professional pride are central. The second is that most of the innovations found aimed at addressing labor shortages are ameliorative rather than solutions, leading to the development of the concept of “coping innovations.”Both of these processes are symptomatic of “innovation on a shoestring” due to structural conditions. Certain, arguably beneficial, aspects of these constraints are identified, such as activities directed towards enhancing person-centered approaches to clients/patients and colleagues, less ‘technologization’ of care contact and opening up opportunities for non-traditional occupational and social groups in health and care work. Non-beneficial aspects of these constraints include heightened work intensity and employee turnover, an overtaxing of the Florence Nightingale ethos, and incomplete or unsatisfactory training and career development programs.
