- The bow shock is the first boundary the solar wind encounters as it approaches planets or comets. The Rosetta spacecraft was able to observe the formation of a bow shock by following comet 67P/Churyumov-Gerasimenko toward the Sun, through perihelion, and back outward again. The spacecraft crossed the newly formed bow shock several times during two periods a few months before and after perihelion; it observed an increase in magnetic field magnitude and oscillation amplitude, electron and proton heating at the shock, and the diminution of the solar wind further downstream. Rosetta observed a cometary bow shock in its infancy, a stage in its development not previously accessible to in situ measurements at comets and planets.

- Objectives To retrospectively evaluate ophthalmological and neurological outcomes in a Swedish cohort of infants born before 24 weeks gestational age (GA) and explore risk factors for visual impairment. Setting Eye and paediatric clinics in Sweden. Participants Infants screened for retinopathy of prematurity (ROP) (n=399), born before 24 weeks GA, 2007-2018. Cases were excluded if ophthalmological follow-up records could not be traced. Primary and secondary outcome measures Primary outcomes were ophthalmological, including visual acuity (VA), refractive error, strabismus, nystagmus and cerebral visual impairment (CVI). Secondary outcomes comprised neonatal and neurological morbidities. Data were retrospectively retrieved from medical records. Results The 355 assessed children had a median GA of 23 weeks and 2 days and a median birth weight of 565 g. At the last available ophthalmological examination, the median age was 4.8 years (range 0.5-13.2 years). Nystagmus was recorded in 21.1%, strabismus in 34.8%, and 51.0% wore spectacles. Seventy-three of 333 (21.9%) were visually impaired, defined as being referred to a low vision clinic and/or having a VA less than 20/60 at 3.5 years of age or older. ROP treatment was a significant risk factor for visual impairment (OR 2.244, p=0.003). Visually impaired children, compared with children without visual impairment, more often had neurological deficits such as intellectual disability 63.8% versus 33.3% (p<0.001), epilepsy 21.1% versus 7.5% (p=0.001) and autism spectrum disorders 32.8% versus 20.9% (p=0.043). Nine of the 355 children had been diagnosed with CVI. Conclusions Children born before 24 weeks GA frequently had visual impairment in association with neurological deficits. CVI was rarely diagnosed. A multidisciplinary approach for the evaluation and habilitation of these vulnerable infants is warranted. National follow-up guidelines need to be developed and implemented.

In Search of MNC Competitive Advantage : The Role of Foreign Subsidiaries as Creators and Disseminators of Knowledge
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Research on the multinational corporation (MNC) has highlighted the development of knowledge that occurs in geographically dispersed subsidiaries, and several scholars have emphasized the significance of subsidiary knowledge for the success of the MNC. This thesis contributes to the understanding of how knowledge is developed within MNC subsidiaries and how the development of subsidiary knowledge is related to the transfer of subsidiary knowledge and subsidiary impact on the performance of the larger MNC.The empirical setting consists of a combination of quantitative and qualitative data. The results of the empirical studies suggest that the development of subsidiary knowledge is contingent upon the business conditions within the local environment and, in particularly, interactive learning within relationships with important business actors external to the organization. Furthermore, the findings show that the development of knowledge within these subsidiaries is driven not only by external actors, but also by business relationships within the corporation. The results reveal that, whether a subsidiary learns and develops knowledge from external or internal sources has direct implications on how the knowledge can be used and applied by other units within the MNC, which in turn affects the extent to which the subsidiary can contribute to the performance of the MNC. It is also revealed that the barriers to transfer are especially manifest in situations in which a subsidiary is deeply embedded in relationships with demanding customers or suppliers. Thus, the embeddedness of subsidiaries in external relationships is a constraining factor for knowledge transfer. In situations in which the subsidiary is deeply embedded in its local market, the headquarters can influence the transfer across subsidiaries through the use of means such as centres of excellence.

Economic incentives for preserving biodiverse semi-natural pastures with calves from dairy cows

- Economical profitability of pasture-based beef production is necessary for continued maintenance of semi-natural pastures. In a situation of decreased cattle stocks, there is a potential to castrate male calves from dairy cows and raise them as grazing steers instead of intact bulls reared indoors, which is the common way in the Nordic countries. We examined the profitability in model enterprises with either grazing steers or indoor bulls. Within the two genders (steer and bull), there were animals of two breed types (pure dairy breed and dairy x beef crossbreed), which were divided into an intensive or extensive production system. The intensive steer system had one summer on grass and slaughter at 21 months of age whereas the extensive steer system had two summers on grass and slaughter at 28 months of age. All bulls were reared indoors and slaughtered at 15 or 18 months of age. The profitability was calculated as contribution margin (CM; sigma revenues - sigma variable costs) in three different herd sizes (50, 100 and 150 slaughtered animals per year) and in three different regions in Sweden (the southern forest districts Gsk, the southern plain districts Gns, and the lower parts of the northern Nn). In the basic calculation, CM for all steers in large herds with 150 slaughtered animals per year was above zero for all cases in Gns, and for one case in Nn and in Gsk respectively. However, all steer cases had lower CM than the comparable bull system in the basic calculation. Sensitivity analyses demonstrate several possible ways of increasing the competitiveness of the grazing steers, compared to the bulls. Utilization of buildings without opportunity cost resulted in a CM above zero for all cases. Increasing the proportion of semi-natural pastures rendering high agrienvironmental payment and support was another effective mean. Decreasing the winter feed cost and labour demand on pasture reduced the costs, whereas producing premium-price certified pasture beef increased the revenue, all measures further contributing to an improved profitability. Pasture-based beef production from dairy-born steers can be economically viable, especially in large herds and with extensive production systems. Thereby, we conclude this system to has a potential to graze large areas of semi-natural pastures and thereby conserve their biodiversity and cultural values.

- PurposeThis paper aims to develop a conceptual framework and presents a number of propositions relating to why and how multinational companies (MNCs) engage in social innovations. The central focus is on the role of MNC knowledge, networks and power for their involvement in social innovations.Design/methodology/approachThe authors combine literature on social innovations, business innovations and MNC literature, and present a number of propositions dealing with the link between MNC knowledge, networks and power-relations and their potential involvement in social innovations.FindingsThe authors emphasize that when social innovations are embraced by MNCs, the way that these corporations use their knowledge, networks and existing power-relations needs to be adapted to the new conditions present in the social innovation arena.Research limitations/implicationsThe main limitation of this work is that the propositions are based on anecdotal evidence and that they are restricted to literature revolving around a few theoretical concepts (knowledge, networks, power). Against this, the authors suggest that to address the call for more empirical work on MNCs engagement in social innovation, these concepts could be used as a starting point in future empirical investigations.Originality/valueThe paper brings together and outlines a theoretical framework based on three theoretical approaches to the MNC as suggested by the literature: the knowledge-based MNC, differentiated MNC and political MNC. Based on these three perspectives, the key contribution of this paper is to develop a broader understanding of why and how MNCs engage in social innovation and the potential underlying liabilities for this involvement.
