Narrowing the gap between climate science and adaptation action: The role of boundary chains
AbstractBoundary organizations play a critical role at the interface between science and decision making. They create, protect and sustain an interactive space for co-production of science and decision-making while simultaneously bridging the two domains. In this special issue we advance the concept of boundary chains, whereby two or more boundary organizations link together synergistically to influence one another and to leverage each other’s resources and strengths to achieve shared goals. In this process both the level of complementary and embeddedness between these organizations is critical for achieving these goals. Through a series of case studies focusing primarily but not exclusively on climate information use in the United States, we aim to advance scholarship in the field by examining innovation among boundary organizations and testing the boundary chain concept. In doing so, we focus on boundary chains both as a theoretical construct to re-think the structure, function, and adaptability of boundary organizations and as a practical strategy to further increase the usability of climate knowledge for adaptation action across a wider range of users
Creating synergy with boundary chains: Can they improve usability of climate information?
AbstractBoundary organizations facilitate and negotiate the interface between science production and use to improve information usability particularly for climate adaptation. To support the increasing demand for usable climate information and enable adaptation, boundary organizations themselves must innovate to foster more efficient production of usable science and more effective networks of producers and users. A recent innovation centers on the idea of boundary chains, whereby boundary organizations work together to increase efficiencies such as leveraging human and social resources. While this idea holds promise, more work is needed to better understand how and why boundary organizations work together to improve information usability and other beneficial outcomes. In this perspective for the special issue, we propose a new conceptual framework for exploring why and how boundary chains form and for evaluating whether or not they are successful. We then apply the framework to case studies that are discussed in more detail in this special issue. Our framework hinges on the notion that boundary chains that are successful are those that create synergy. In turn, synergy depends on a combination of complementarity, putting two kinds of inputs together results in greater output than either each engaging partner could deliver on their own, and embeddedness, the choices and actions on one side are at least partially influenced by and dependent upon the choices and actions of the other side and vice versa
A rare differential diagnosis to occupational neck pain: bilateral stylohyoid syndrome
Chronic neck pain is widely prevalent and a common source of disability in the working-age population. Etiology of chronic neck pain includes neck sprain, mechanical or muscular neck pain, myofascial pain syndrome, postural neck pain as well as pain due to degenerative changes. We report the case of a 42 year old secretary, complaining about a longer history of neck pain and limited movement of the cervical spine. Surprisingly, the adequate radiologic examination revealed a bilateral ossification of the stylohyoid ligament complex. Her symptoms remained intractable from conservative treatment consisting of anti-inflammatory medication as well as physical therapy. Hence the patient was admitted to surgical resection of the ossified stylohyoid ligament complex. Afterwards she was free of any complaints and went back to work. Therefore, ossification of the stylohyoid ligament complex causing severe neck pain and movement disorder should be regarded as a rare differential diagnosis of occupational related neck pain

Cannabidiol Exerts a Neuroprotective and Glia-Balancing Effect in the Subacute Phase of Stroke
Pharmacological agents limiting secondary tissue loss and improving functional outcomes after stroke are still limited. Cannabidiol (CBD), the major non-psychoactive component of
Cannabis sativa, has been proposed as a neuroprotective agent against experimental cerebral ischemia.
The effects of CBD mostly relate to the modulation of neuroinflammation, including glial activation.
To investigate the effects of CBD on glial cells after focal ischemia in vivo, we performed time-lapse
imaging of microglia and astroglial Ca2+ signaling in the somatosensory cortex in the subacute phase
of stroke by in vivo two-photon laser-scanning microscopy using transgenic mice with microglial
EGFP expression and astrocyte-specific expression of the genetically encoded Ca2+ sensor GCaMP3.
CBD (10 mg/kg, intraperitoneally) prevented ischemia-induced neurological impairment, reducing
the neurological deficit score from 2.0 ± 1.2 to 0.8 ± 0.8, and protected against neurodegeneration,
as shown by the reduction (more than 70%) in Fluoro-Jade C staining (18.8 ± 7.5 to 5.3 ± 0.3).
CBD reduced ischemia-induced microglial activation assessed by changes in soma area and total
branch length, and exerted a balancing effect on astroglial Ca2+ signals. Our findings indicate that
the neuroprotective effects of CBD may occur in the subacute phase of ischemia, and reinforce its
strong anti-inflammatory property. Nevertheless, its mechanism of action on glial cells still requires
further studies
Implications from Responsible Human-Robot Interaction with Anthropomorphic Service Robots for Design Science
Accelerated by the COVID-19 pandemic, anthropomorphic service robots are continuously penetrating various domains of our daily lives. With this development, the urge for an interdisciplinary approach to responsibly design human-robot interaction (HRI), with particular attention to human dignity, privacy, compliance, and transparency, increases. This paper contributes to design science, in developing a new artifact, i.e., an interdisciplinary framework for designing responsible HRI with anthropomorphic service robots, which covers the three design science research cycles. Furthermore, we propose a multi-method approach by applying this interdisciplinary framework. Thereby, our finding offer implications for designing HRI in a responsible manner
The effects of an adapted mental health literacy curriculum for secondary school students in Germany on mental health knowledge and help-seeking efficacy: results of a quasi-experimental pre-post evaluation study
BackgroundBecause the majority of mental illnesses develop early in life, effective preventative public mental health interventions are needed. Interventions fostering mental health literacy can be used to enhance personal resources and capacities to facilitate mental health care and thus, address help-seeking barriers. A Canadian mental health literacy school curriculum was adapted, piloted, and evaluated for the use in German schools. The study presents the intervention’s effects on mental health knowledge and help-seeking efficacy among 10th grade students in Germany.Methods10th grade students (aged 14–17 years old) from one secondary school participated in a pre- and post-intervention control group study. Both groups completed a questionnaire at two time points assessing mental health knowledge and help-seeking efficacy. Repeated measure analysis of variance (ANOVA) was employed to evaluate the intervention’s effects.ResultsData from 188 students was eligible for analysis. The analysis of the baseline data reveals a high comparability of the two groups in terms of demographics, and initial mental health knowledge and help-seeking efficacy scores. ANOVA results showed significant improvements for the intervention group having a large effect size for mental health knowledge (f = 0.574, p < 0.001, partial η2 = 0.25) and a medium effect size for help-seeking efficacy (f = 0.311, p < 0.001, partial η2 = 0.09).ConclusionThe first-time application and evaluation of an adapted mental health literacy school curriculum shows significant increases in mental health knowledge and help-seeking efficacy, two core dimensions of mental health literacy, among 10th grade students in Germany. Further studies are needed to confirm these results as well as have a more in-depth analysis on the interrelations of the different dimensions of mental health knowledge and help-seeking practices
LPS-Induced Systemic Inflammation Affects the Dynamic Interactions of Astrocytes and Microglia with the Vasculature of the Mouse Brain Cortex
The Neurovascular Unit (NVU), composed of glia (astrocytes, oligodendrocytes, microglia),
neurons, pericytes and endothelial cells, is a dynamic interface ensuring the physiological functioning
of the central nervous system (CNS), which gets affected and contributes to the pathology of several
neurodegenerative diseases. Neuroinflammation is a common feature of neurodegenerative diseases
and is primarily related to the activation state of perivascular microglia and astrocytes, which
constitute two of its major cellular components. Our studies focus on monitoring in real time the
morphological changes of perivascular astrocytes and microglia, as well as their dynamic interactions
with the brain vasculature, under physiological conditions and following systemic neuroinflammation
triggering both microgliosis and astrogliosis. To this end, we performed 2-photon laser scanning
microscopy (2P-LSM) for intravital imaging of the cortex of transgenic mice visualizing the dynamics
of microglia and astroglia following neuroinflammation induced by systemic administration of
the endotoxin lipopolysaccharide (LPS). Our results indicate that following neuroinflammation the
endfeet of activated perivascular astrocytes lose their close proximity and physiological cross-talk
with vasculature, an event that most possibly contributes to a loss of blood–brain barrier (BBB)
integrity. At the same time, microglial cells become activated and exhibit a higher extent of physical
contact with the blood vessels. These dynamic responses of perivascular astrocytes and microglia are
peaking at 4 days following LPS administration; however, they still persist at a lower level at 8 days
after LPS injection, revealing incomplete reversal of inflammation affecting the glial properties and
interactions within the NVU
Responsible Human-Robot Interaction with Anthropomorphic Service Robots: State of the Art of an Interdisciplinary Research Challenge
Anthropomorphic service robots are on the rise. The more capable they become and the more regular they are applied in real-world settings, the more critical becomes the responsible design of human-robot interaction (HRI) with special attention to human dignity, transparency, privacy, and robot compliance. In this paper we review the interdisciplinary state of the art relevant for the responsible design of HRI. Furthermore, directions for future research on the responsible design of HRI with anthropomorphic service robots are suggested
