- A main issue in Swedish school debate is the question of how to teach the student a common value system based on democracy and western humanism. The debate is rather intense, to say the least. Not only is the premise that there exists one value system that we share a target for critique, but there is also the question of what value education is or could be. There is, as well, quite a body of research on children's moral development, where many take as their departure the work of Kohlberg. However, there has been little or no attention on how the individual learner conceptualizes and makes meaning out of ethical issues. That is, descriptions of processes. In this paper we will present what we take to be urgent questions that need to be investigated against the background of prior research and practical work at Södra teatern in Stockholm, Sweden. For eight years in a row, Södra teatern has had as a main project to lead a practice on the subject of philosophy with children. Several groups of youths in the age of nine to eighteen have regularly met to discuss philosophical thoughts and problems, which in a democratic manner are settled for discussion by the participants. Today this philosophical practice has spread to the north of Sweden. In Backman's final exam within the teacher education she has explored the development of children's (7‐8 years old) ability to argue for different ethical positions, both verbally and in writing and painting. This practice has been inspired by the tradition at Södra teatern, but customized to fit a regular school class in Luleå, with very little experience of philosophical discussion. In the very short period of five weeks Backman has been able to see quite significant changes in the children's ability to argue for their ethical positions. The study was initiated by examining some argumentative abilities of the pupils, for instance the ability of expressing an argument for an ethical position in writing. In the final part of the study, the same ability was examined in very similarcircumstances, and the augment of expressed arguments in writing was significant. Another consideration that was raised as a consequence of the study regards the pupil's conceptualizing of ethical issues. In some conversations about the notion of justice it became clear that children interpreted the term very differently. This is not very surprising but important to pay further attention to. As mentioned earlier, there has been very little attention on how individual children conceptualize ethical issues. In this paper we argue that more interest should be put on investigating these issues in more depth, and we will do this by an outlining of a research application.

Annan publikation (populärvet., debatt m.m.)abstract
- In this paper, we are mainly concerned with coherentism as an approach to ethical dialog in school. We have two different but connected aims with the paper. The first aim is to say something about general philosophical questions relating to coherentism as a theory in metaethics, and especially in relation to value education; the second aim is to explore some possible implications of coherentism as a method in studying the enterprise of discussing ethical issues and questions with children as well as the study of the actual ethical discussion in school. Furthermore, we evaluate the connection between a coherentistic approach to justification and the methodological parts of a Philosophy with Children, or Community of Inquiry, approach to ethics in school. Related to this, we scrutinize what implications this has for evaluating ethical learning within Philosophy with Children, or Community of Inquiry, as well as implications for evaluation of the Philosophy with Children, or Community of Inquiry, approaches as methods for dealing with ethical matters in school.

Konferensbidrag (övrigt vetenskapligt)abstract
- This article is about a coming project concerning a coherentist approach to ethics in school. The project has two main parts; one theoretical and one empirical. The former focuses on philosophical problems and issues concerning coherentism as a metaethical position in general, and particularly when applied to the field of value education, and the latter aims to study some consequences of a coherentist approach to the study of discussing ethical matters with children. Metaethical coherentism is a position in the discussion about justification of moral judgements. According to coherentism, we build some kind of web in which different moral judgements are connected by some justification‐relation or the like. Some judgements might be more central than others, but these can be justified by the more particular and peripheral ones, and vice versa. Coherentism differs from foundationalism, according to which there are some foundational judgements that are not justified by any other judgements. The rest of our judgements are justified if they are justified by this foundation. We wish to study what benefits a coherentist approach might have in the study of ethical discussions in school. In Sweden, the educational system has as one of its main purposes to mediate a "value foundation" based on "Christian ethical tradition and western humanism" to the pupils. Suppose now that you have a foundationalist approach to ethical discussion in schools, as many seem to have had historically, and that some pupil expresses the judgement that some of his classmates have a lower value than him, due to the colour of their skin. This judgement conflicts with the judgement that the colour of ones skin does not have any bearing of ones value, included in the value foundation of the school. According to a foundationalist, we here have a conflict between foundational values, or so we can suppose. In this case, there is nothing obvious to do to resolve this conflict, because the foundational values cannot be justified; it is supposed that we simply realise the correctness of them by our moral intuition, or the like. A coherentist, on the other side, could point to how these two different judgements gain different amount of justification from other judgements, and thereby hopefully find consensus, and hence dissolve the conflict. Coherentism is not theoretically unproblematic, though. One problem is how to understand the justification‐relation. What does it mean that two propositions justify each other? Philosophers have discussed several different proposals. We give a new proposal, based on some of Arne Naess' theories. With regard to methods for ethical discussion in relation to a coherentistic approach, it seems as a "philosophy with children" approach will seem as a natural choice.

- Patients diagnosed with diffuse large B-cell lymphoma (DLBCL) show varying responses to conventional therapy, and this might be contributed to the differentiation stage of the tumor B-cells. The aim of the current study was to evaluate a panel of kinases (ZAP70, PKC-beta I and II and phosphorylated PKB/Akt) and phosphatases (PTEN, SHP1 and SHP2) known to be frequently deregulated in lymphoid malignancies. De novo DLBCL cases were divided into two subgroups, the germinal center (GC) group (14/28) and the non-germinal center (non-GC) or activated B-cell (ABC) group (14/28). ZAP70 and PKC-beta II were expressed in a significantly higher percentage of tumor cells in the clinically more aggressive non-GC group compared with the prognostically favourable GC group. Also, the subcellular localization of PKC-beta I and II differed in DLBCL cells, with the PKC-beta I isoform being expressed in both the cytoplasm and nucleus, while PKC-beta II was found exclusively in the cytoplasm. Loss of nuclear PTEN correlated with poor survival in cases from both subgroups. In addition, five cell lines of DLBCL origin were analyzed for protein expression and for mRNA levels of PTEN and SHP1. For the first time, we show that ZAP70 is expressed in a higher percentage of tumor cells in the aggressive non-GC subgroup of DLBCL and that PKC-beta I and II are differently distributed in the two prognostic subgroups of de novo DLBCL.

- The interactions between consumers and prey, and their impact on biomass distribution among trophic levels, are central issues in both empirical and theoretical ecology. In a long-term experiment, where all organisms, including the top predator, were allowed to respond to environmental conditions by reproduction, we tested predictions from `prey-dependent' and `ratio-dependent' models. Prey-dependent models made correct predictions only in the presence of strong interactors in simple food chains, but failed to predict patterns in more complex situations. Processes such as omnivory, consumer excretion, and unsuitable prey-size windows (invulnerable prey) increased the complexity and created patterns resembling ratio-dependent consumption. However, whereas the prey-dependent patterns were created by the mechanisms predicted by the model, ratio-dependent patterns were not, suggesting that they may be right for the wrong reason'. We show here that despite the enormous complexity of ecosystems, it is possible to identify and disentangle mechanisms responsible for observed patterns in community structure, as well as in biomass development of organisms ranging in size from bacteria to fish.

Effects of small-scale habitat fragmentation on predator-prey interactions in a temperate sea grass system

- During the last decades, fragmentation has become an important issue in ecological research. Habitat fragmentation operates on spatial scales ranging over several magnitudes from patches to landscapes. We focus on small-scale fragmentation effects relevant to animal foraging decision making that could ultimately generate distribution patterns. In a controlled experimental environment, we tested small-scale fragmentation effects in artificial sea grass on the feeding behaviour of juvenile cod (Gadus morhua). Moreover, we examined the influence of fragmentation on the distribution of one of the juvenile cod's main prey resources, the grass shrimp (Palaemon elegans), in association with three levels of risk provided by cod (no cod, cod chemical cues and actively foraging cod). Time spent by cod within sea grass was lower in fragmented landscapes, but total shrimp consumption was not affected. Shrimp utilised vegetation to a greater extent in fragmented treatments in combination with active predation. We suggest that shrimp choose between sand and vegetation habitats to minimize risk of predation according to cod habitat-specific foraging capacities, while cod aim to maximize prey-dependent foraging rates, generating a habitat-choice game between predator and prey. Moreover, aggregating behaviour in grass shrimp was only found in treatments with active predation. Hence, we argue that both aggregation and vegetation use are anti-predator defence strategies applied by shrimp. We therefore stress the importance of considering small-scale behavioural mechanisms when evaluating consequences from habitat fragmentation on trophic processes in coastal environments.

- Background Experimental animal studies and previous randomized trials suggest an improvement in mortality and neurologic function with induced hypothermia after cardiac arrest. International guidelines advocate the use of a target temperature management of 32 degrees C to 34 degrees C for 12 to 24 hours after resuscitation from out-of-hospital cardiac arrest. A systematic review indicates that the evidence for recommending this intervention is inconclusive, and the GRADE level of evidence is low. Previous trials were small, with high risk of bias, evaluated select populations, and did not treat hyperthermia in the control groups. The optimal target temperature management strategy is not known. less thanbrgreater than less thanbrgreater thanMethods The TTM trial is an investigator-initiated, international, randomized, parallel-group, and assessor-blinded clinical trial designed to enroll at least 850 adult, unconscious patients resuscitated after out-of-hospital cardiac arrest of a presumed cardiac cause. The patients will be randomized to a target temperature management of either 33 degrees C or 36 degrees C after return of spontaneous circulation. In both groups, the intervention will last 36 hours. The primary outcome is all-cause mortality at maximal follow-up. The main secondary outcomes are the composite outcome of all-cause mortality and poor neurologic function (cerebral performance categories 3 and 4) at hospital discharge and at 180 days, cognitive status and quality of life at 180 days, assessment of safety and harm. less thanbrgreater than less thanbrgreater thanDiscussion The TTM trial will investigate potential benefit and harm of 2 target temperature strategies, both avoiding hyperthermia in a large proportion of the out-of-hospital cardiac arrest population.

Effects of enrichment on simple aquatic food webs

- Simple models, based on Lotka-Volterra types of interactions between predator and prey, predict that enrichment will have a destabilizing effect on populations and that equilibrium population densities will change at the top trophic level and every second level below. We experimentally tested these predictions in three aquatic food web configurations subjected to either high or low nutrient additions. The results were structured by viewing the systems as either food chains or webs and showed that trophic level biomass increased with enrichment, which contradicts food chain theory. However, within each trophic level, food web configuration affected the extent to which different functional groups responded to enrichment. By dividing trophic levels into functional groups, based on vulnerability to consumption, we were able to identify significant effects that were obscured when systems were viewed as food chains. The results support the prediction that invulnerable prey may stabilize trophic-level dynamics by replacing other, more vulnerable prey. Furthermore, the vulnerable prey, such as Daphnia and edible algae, responded as predicted by the paradox of enrichment hypothesis; that is, variability in population density increased with enrichment. Hence, by describing ecosystems as a matrix of food web interactions, and by recognizing the interplay between interspecific competition and predation, a more complete description of the ecosystem function was obtained compared to when species were placed into distinct trophic levels.
