Lost Pathways of Urban Development
Photographic images from Ho Chi Minh City’s Thủ Thiêm Peninsula draw attention to now-vanished trees and pathways from a place that has been demolished for the sake of urban expansion. The trees and pathways in these photographs evoke an aspect of sociality often overlooked in the logocentric anthropological and geographical literature on development-induced evictions. Attention to images draws attention to the history of non-human nature and to lost pathways of urban development, which in turn emphasizes their uses and the practices which maintained them, revealing the interconnection between human sociality and the non-human world. Unlike the "tragedy of the commons," which describes common resources extinguished or depleted by unregulated use, these elements appear as a collective resource, produced and cared for by their users. Reflecting on photographic images taken before and during a period of mass eviction inspires a rethinking of the idea of the commons, crafted through a cultural approach that attends to the material landscape, the role of the non-human in social relationships, and the social production of landscapes

Inter-organizational network management in an innovation context:combining ego and whole network perspective
Although there is growing interest into the research field of inter-organizational innovation networks, few attempts have been made to develop systematic methods for the active management of such networks. This is especially true for approaches combining the view of single actors and the network as a whole. In response to this gap, this research presents a new method for the management of inter-organizational networks that can help to increase innovation outcome. The introduced approach accomplishes two goals. Firstly, it provides guidance for the measurement of the current collaboration status of a network, its optimal future collaboration status and the gap between them. Secondly, it provides systematics for the development of clear network management strategies for each network actor for closing this collaboration gap. As a result, better exploitation of existing collaboration potential is expected to increase innovation output. The method builds upon work by Kohl et al. (2015) who approached network management on a whole network level providing a solution for the management of entire networks and Ojasalo (2004) who suggested a network management method taking the perspective of a single network actor on the so called ego level. The novelty value of the presented method lies in the demonstration of how these different levels of network management can be combined. The two levels of analysis are linked through reliance on the same data set. The developed method is demonstrated through a case study. The analysis builds upon a questionnaire asking network actors for an estimation of the current collaboration status and a future collaboration potential amongst them. Social network analysis software was used to calculate network measures such as the level of density and to visualize the network graphically. As a result customized strategies for improving collaboration within the investigated network are presented
Co-operative Nordic Research
This report has a two-fold objective. -To identify the changing risk management needs in the private and public sectors and the corresponding needs for development of risk analysis methods and related practices. -To list examples of projects where Nordic co-operation between industry, authorities and universities can be effective for increasing the contribution of risk management to industrial growth and a sustainable society. A Nordic expert group, funded by the Nordic Industrial Fund, identified the urgent need for co-operative Nordic risk management research and suggested a structure for co-operation and cross-disciplinary research and for dissemination of knowledge and implementation. The group also specified research areas and project ideas for future development into actual research projects. A workshop with participants from the Nordic countries was one source of ideas. The expert group in addition identified a number of basic resource areas necessary for the development of more efficient risk management industry and which would benefit from Nordic co-operation. A Nordic risk management academy and a Nordic risk management network should be formed. Also a Nordic graduate school on safety and risk management for PhD students should be organized on a Nordic basis in order to ensure competence at all Institutes of Technology, all Business Schools and other education bodies of importance for risk management
Explain yourself! Effects of Explanations in Human-Robot Interaction
Recent developments in explainable artificial intelligence promise the
potential to transform human-robot interaction: Explanations of robot decisions
could affect user perceptions, justify their reliability, and increase trust.
However, the effects on human perceptions of robots that explain their
decisions have not been studied thoroughly. To analyze the effect of
explainable robots, we conduct a study in which two simulated robots play a
competitive board game. While one robot explains its moves, the other robot
only announces them. Providing explanations for its actions was not sufficient
to change the perceived competence, intelligence, likeability or safety ratings
of the robot. However, the results show that the robot that explains its moves
is perceived as more lively and human-like. This study demonstrates the need
for and potential of explainable human-robot interaction and the wider
assessment of its effects as a novel research direction
The quality of different types of child care at 10 and 18 months. A comparison between types and factors related to quality.
The quality of care offered in four different types of non-parental child care to 307 infants at 10 months old and 331 infants at 18 months old was compared and factors associated with higher quality were identified. Observed quality was lowest in nurseries at each age point, except that at 18 months they offered more learning activities. There were few differences in the observed quality of care by child-minders, grandparents and nannies, although grandparents had somewhat lower safety and health scores and offered children fewer activities. Cost was largely unrelated to quality of care except in child-minding, where higher cost was associated with higher quality. Observed ratios of children to adults had a significant impact on quality of nursery care; the more infants or toddlers each adult had to care for, the lower the quality of the care she gave them. Mothers' overall satisfaction with their child's care was positively associated with its quality for home-based care but not for nursery settings
Urinary amine and organic acid metabolites evaluated as markers for childhood aggression : the ACTION biomarker study
Biomarkers are of interest as potential diagnostic and predictive instruments in personalized medicine. We present the first urinary metabolomics biomarker study of childhood aggression. We aim to examine the association of urinary metabolites and neurotransmitter ratios involved in key metabolic and neurotransmitter pathways in a large cohort of twins (N = 1,347) and clinic-referred children (N = 183) with an average age of 9.7 years. This study is part of ACTION (Aggression in Children: Unraveling gene-environment interplay to inform Treatment and InterventiON strategies), in which we developed a standardized protocol for large-scale collection of urine samples in children. Our analytical design consisted of three phases: a discovery phase in twins scoring low or high on aggression (N = 783); a replication phase in twin pairs discordant for aggression (N = 378); and a validation phase in clinical cases and matched twin controls (N = 367). In the discovery phase, 6 biomarkers were significantly associated with childhood aggression, of which the association of O-phosphoserine (beta = 0.36; SE = 0.09; p = 0.004), and gamma-L-glutamyl-L-alanine (beta = 0.32; SE = 0.09; p = 0.01) remained significant after multiple testing. Although non-significant, the directions of effect were congruent between the discovery and replication analyses for six biomarkers and two neurotransmitter ratios and the concentrations of 6 amines differed between low and high aggressive twins. In the validation analyses, the top biomarkers and neurotransmitter ratios, with congruent directions of effect, showed no significant associations with childhood aggression. We find suggestive evidence for associations of childhood aggression with metabolic dysregulation of neurotransmission, oxidative stress, and energy metabolism. Although replication is required, our findings provide starting points to investigate causal and pleiotropic effects of these dysregulations on childhood aggression
Hormone affinity and fibril formation of piscine transthyretin: the role of the N-terminal
Transthyretin (TTR) transports thyroid hormones (THs), thyroxine (T4) and
triiodothyronine (T3) in the blood of vertebrates. TH-binding sites are highly conserved in vertebrate TTR however, piscine TTR has a longer N-terminus which is thought to influence TH-binding affinity and may influence TTR stability. We produced
recombinant wild-type sea bream TTR (sbTTRWT) plus two mutants in which six
(sbTTRM6) and twelve (sbTTRM12) N-terminal residues were removed. Ligandbinding
studies revealed similar affinities for T3 (Kd=10.6±1.7nM) and T4 (Kd=9.8±0.97nM) binding to sbTTRWT. Affinity for THs was unaltered in sbTTRM12 but sbTTRM6 had poorer affinity for T4 (Kd=252.3±15.8nM) implying that some residues in the N-terminus can influence T4 binding. sbTTRM6 inhibited acid-mediated fibril formation in vitro as shown by fluorometric measurements using thioflavine-T.In contrast, fibril formation by sbTTRM12 was significant, probably due to decreased stability of the tetramer. Such studies also suggested that sbTTRWT is more resistant to fibril formation than human TTR
Improvement of Insulin Sensitivity after Lean Donor Feces in Metabolic Syndrome Is Driven by Baseline Intestinal Microbiota Composition
The intestinal microbiota has been implicated in insulin resistance, although evidence regarding causality in humans is scarce. We therefore studied the effect of lean donor (allogenic) versus own (autologous) fecal microbiota transplantation (FMT) to male recipients with the metabolic syndrome. Whereas we did not observe metabolic changes at 18 weeks after FMT, insulin sensitivity at 6 weeks after allogenic FMT was significantly improved, accompanied by altered microbiota composition. We also observed changes in plasma metabolites such as gamma-aminobutyric acid and show that metabolic response upon allogenic FMT (defined as improved insulin sensitivity 6 weeks after FMT) is dependent on decreased fecal microbial diversity at baseline. In conclusion, the beneficial effects of lean donor FMT on glucose metabolism are associated with changes in intestinal microbiota and plasma metabolites and can be predicted based on baseline fecal microbiota composition.Peer reviewe
Palatal development of preterm and low birthweight infants compared to term infants – What do we know? Part 3: Discussion and Conclusion
BACKGROUND: It has been hypothesized that prematurity and adjunctive neonatal care is 'a priori' a risk for disturbances of palatal and orofacial development which increases the need for later orthodontic or orthognathic treatment. As results on late consequences of prematurity are consistently contradictory, the necessity exists for a fundamental analysis of existing methodologies, confounding factors, and outcomes of studies on palatal development in preterm and low birthweight infants. METHOD: A search of the literature was conducted based on Cochrane search strategies including sources in English, German, and French. Original data were recalculated from studies which primarily dealt with both preterm and term infants. The extracted data, especially those from non-English paper sources, were provided unfiltered in tables for comparison (Parts 1 and 2). RESULTS: Morphology assessment of the infant palate is subject to non-standardized visual and metrical measurements. Most methodologies are inadequate for measuring a three-dimensional shape. Several confounding factors were identified as causes contributing to disturbances of palatal and orofacial development. CONCLUSION: Taking into account the abovementioned shortcomings, the following conclusions may be drawn for practitioners and prospective investigators of clinical studies. 1) The lack of uniformity in the anatomical nomenclature of the infant's palate underlines the need for a uniform definition. 2) Metrically, non-intubated preterm infants do not exhibit different palatal width or height compared to matched term infants up to the corrected age of three months. Beyond that age, no data on the subject are currently available. 3) Oral intubation does not invariably alter palatal morphology of preterm and low birthweight infants. 4) The findings on palatal grooving, height, and asymmetry as a consequence of orotracheal intubation up to the age of 11 years are inconsistent. 5) Metrically, the palates of orally intubated infants remain narrower posteriorly, beginning at the second deciduous molar, until the age of 11 years. Beyond that age, no data on the subject are currently available. 6) There is a definite need for further, especially metrical, longitudinal and controlled trials on palatal morphology of preterm and low birthweight infants with reliable measuring techniques. 7) None of the raised confounding factors for developmental disturbances may be excluded until evident results are presented. Thus, early orthodontic and logopedic control of formerly premature infants is recommended up to the late mixed dentition stage
