description: Η παρούσα μελέτη αποτελεί ανασκόπηση της διεθνούς βιβλιογραφίας σχετικά με τις συνδέσεις και τους κλάδους μεταξύ των τελικών νευρικών στελεχών του άνω άκρου. Πραγματοποιήθηκε αναζήτηση στην ηλεκτρονική βάση (pubmed), oι λέξεις κλειδιά που χρησιμοποιήθηκαν ήταν “nerve communication, nerve connection, nerve anastomosis”, “upper limb, arm, forearm, hand”, “variant” με τον συνδυασμό “and” και “or”. Συμπεριλήφθηκαν πτωματικές, κλινικές και απεικονιστικές μελέτες.Έγινε αναζήτηση σε 15.000 τίτλους άρθρων εκ των οποίων 134 ταυτοποιήθηκαν ως σχετικά με το θέμα και κατόπιν μελέτης αυτών, χρησιμοποιήθηκαν 90 για τους σκοπούς της παρούσας μελέτης, καθώς και 2 εγχειρίδια ανατομικής. Γίνεται εκτενής αναφορά στις πιο συχνά απαντούμενες, αλλά και σε πιο ξεχωριστές περιπτώσεις επικοινωνίας μεταξύ των νευρικών στελεχών του άνω άκρου. Επιχειρείται μια προσπάθεια ομαδοποίησης αυτών των νευρικών συνδέσεων και διαίρεσης του ειδικού μέρους αυτής της εργασίας σύμφωνα με τοπογραφικά κριτήρια. Έτσι η πρώτη ομάδα νευρικών συνδέσεων αφορά την ωμική χώρα, η δεύτερη τον βραχίονα, η τρίτη το αντιβράχιο και η τέταρτη τον καρπό και το χέρι. Τα χειρουργικά τραύματα και διάφορες αναισθησιολογικές πράξεις καθιστούν τη γνώση των παραλλαγών αυτών πολύ σημαντική. Στον νευροφυσιολογικό έλεγχο και σε απεικονιστικές εξετάσεις στην περιοχή του άνω άκρου η ύπαρξη αναστομώσεων μεταξύ των νεύρων, επηρεάζει τα αποτελέσματα και την ερμηνεία αυτών στη δίαγνωση.

Modeling source parameters of quasi-periodic tremor

Year: 2020

description: Modeling harmonic tremor recorded at volcanoes is an essential practice in improving eruption forecasting methods and warning systems. We model the conduit dynamics of quasi-periodic tremor (chugging) recorded at Karymsky, Tungurahua, and Fuego volcanoes to estimate its source characteristics. Chugging mechanisms are estimated using two theoretical models originally derived in Garcés [1997, doi: https://doi.org/10.1029/1999JB900096] and Girona et al. [2019, doi: https://doi.org/10.1029/2019JB017482], respectively. Comparisons of the conduit and fluid output parameters suggests that chugging is primarily limited to near-surface oscillations and outgassing due to an accumulation of gas between eruptive episodes. The modeled results indicate clustered release of volatiles exsolved from a deeper magma conduit region, triggered by an initial explosion. This interpretation is consistent with both infrasonic and seismic observations at each volcano.

description: Open clusters are historically regarded as single-aged stellar populations representative of star formation within the Galactic disk. Recent literature has questioned this view, based on discrepant Na abundances relative to the field, and concerns about the longevity of bound clusters contributing to a selection bias: perhaps long-lived open clusters are chemically different to the star formation events that contributed to the Galactic disk. We explore a large sample of high resolution Na, O, Ba & Eu abundances from the literature, homogenized as much as reasonable including accounting for NLTE effects, variations in analysis and choice of spectral lines. Compared to a template globular cluster and representative field stars, we find no significant abundance trends, confirming that the process producing the Na-O anti-correlation in globular clusters is not present in open clusters. Furthermore, previously reported Na-enhancement of open clusters is found to be an artefact of NLTE effects, with the open clusters matching a subset of chemically tagged field stars.

description: Several emergent phenomena and phases in solids arise from configurations of the electronic Berry phase in momentum space that are similar to gauge field configurations in real space such as magnetic monopoles. We show that the momentum-space analogue of the "axion electrodynamics" term $\mathbf{E}\cdot\mathbf{B}$ plays a fundamental role in a unified theory of Berry-phase contributions to optical gyrotropy in time-reversal invariant materials and the chiral magnetic effect. The Berry-phase mechanism predicts that the rotatory power along the optic axes of a crystal must sum to zero, a constraint beyond that stipulated by point group symmetry, but observed to high accuracy in classic experimental observations on $α$-quartz. Furthermore, the Berry mechanism provides a microscopic basis for the surface conductance at the interface between gyrotropic and nongyrotropic media.

description: To investigate the origin of the enhanced $T_c$ ($\approx$ 110 K) of the trilayer cuprate superconductor Bi$_{2}$Sr$_{2}$Ca$_{2}$Cu$_{3}$O$_{10+δ}$ (Bi-2223), we have performed systematic magnetoresistance (MR) measurements on this superconductor, as well as on the bilayer superconductor, Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$ (Bi-2212). The in-plane coherence length, $ξ_{ab}$, and the specific-heat jump, $ΔC$, have been estimated using the theory of renormalized superconductive fluctuations, and the doping dependence of these parameters has been qualitatively explained using the Fermi arc approach. A detailed comparison of the superconducting parameters with $T_c$ for these compounds suggests that an additional superconducting condensation energy exists, due to an increase in the number of stacking CuO$_{2}$ planes in a unit cell.

Αρχικά έγινε μια εκτενής παρουσίαση στον βίο του Αγίου Γρηγορίου για να κατανοηθεί το καππαδοκικό περιβάλλον, η διαμόρφωση των θεολογικών του σπουδών λόγω της στενής σχέση του με τον Μέγα Βασίλειο, και να παρουσιαστούν τα κυριότερα στοιχεία του βίου του όπως η άνοδος του στον θρόνο της Κωνσταντινουπόλεως και η συμμετοχή του στην ΄Β Οικουμενική Σύνοδο. Στη συνέχεια παρουσιάσαμε το ιστορικό και γραμματολογικό πλαίσιο για να δείξουμε για ποιον λόγο εκφωνήθηκαν οι παραπάνω λόγοι, τον τόπο και το χρόνο που συνέβησαν καθώς επίσης και ρητορικη δεινότητα των λόγω του Αγίου Γρηγορίου μέσα από τον τρόπο που συντάσσει τα κείμενα του χρησιμοποιώντας πρωτίστως το διδακτικό και λόγιο ύφος. Τέλος ασχοληθήκαμε με την εξέταση δογματικής φύσεων στοιχείων που υπάρχουν στους παραπάνω λόγους και αφορούν τα τριαδολογικά και οικονομικά στοιχεία της διδασκαλίας του Αγίου. Συγκεκριμένα γίνεται λόγος στις ενδοτριαδικές σχέσεις των προσώπων, στην ουσία και στις ενέργειες του Θεού, στις υποστάσεις τις Τριάδος, στα συγκεκριμένα υποστατικά ιδιώματα των θείων προσώπων και φυσικά στην θεία Οικονομία.
description: The purpose of the master's thesis is to detect and capture doctrinal elements about triadology and economy according to Saint Gregory the Theologian based on the discourses at the Epiphany, at Easter and about the doctrine and situations of bishops. Initially, an extensive presentation of the life of Saint Gregory was made in order to understand the Cappadocian environment, the formation of his theological studies due to his close relationship with Basil the Great, and to present the main elements of his life such as his rise to the throne of Constantinople and his participation in the Second Ecumenical Council. Then we presented the historical and grammatical context to show why the above speeches were spoken, the place and time they occurred as well as the rhetorical skill of Saint Gregory's speeches through the way he composes his texts using primarily didactic and scholarly style. Finally, we dealt with the examination of the doctrinal nature of elements present in the above discourses and concerning the triadological and economic elements of the Saint's teaching. In particular, it talks about the intra-trinitarian relationships of the persons, the essence and the actions of God, the hypostasis of the Trinity, the specific hypostatic idioms of the divine persons and of course the divine Economy.

description: The line tension of an electrolyte wetting a non-polar substrate is computed analytically and numerically. The results show that, depending on the value of the apparent contact angle, positive or negative line tension values may be obtained. Furthermore, a significant difference between Young's contact angle and the apparent contact angle measured several Debye lengths remote from the three-phase contact line occurs. When applying the results to water wetting highly charged surfaces, line tension values of the same order of magnitude as found in recent experiments can be achieved. Therefore, the theory presented may contribute to the understanding of line tension measurements and points to the importance of the electrostatic line tension. Being strongly dependent on the interfacial charge density, electrostatic line tension is found to be tunable via the pH value of the involved electrolyte. As a practical consequence, the stability of nanoparticles adsorbed at fluid-fluid interfaces is predicted to be dependent on the pH value. The theory is suited for future incorporation of effects due to surfactants where even larger line tension values can be expected.

description: Λόγω των οικονομικών περιορισμών που έχουν επιβληθεί στο ελληνικό κράτος από τα μνημόνια που συμφωνήθηκαν με τους πιστωτές (Ευρωπαϊκή Επιτροπή, Ευρωπαϊκή Κεντρική Τράπεζα, Διεθνές Νομισματικό Ταμείο), στο πλαίσιο ενός προγράμματος διάσωσης της ελληνικής οικονομίας, οι δημόσιες δαπάνες για τα νοσοκομεία έχουν μειωθεί τελευταία. Είναι απαραίτητη η χρήση σύγχρονων μεθόδων διαχείρισης, όπως ο στρατηγικός σχεδιασμός, στη σημερινή εποχή που η οικονομική κρίση ακολουθείται από μια κρίση στο σύστημα υγείας που προκαλείται από την ανάπτυξη της πανδημίας SARS-Cov-2. Μέσω αυτού, οι ενέργειες των δημόσιων νοσοκομείων καθοδηγούνται με πειθαρχημένο και μεθοδικό τρόπο, ώστε να μπορούν να διατηρήσουν την οντότητά τους, να αυξήσουν τη δυναμικότητά τους και να εκπληρώσουν την αποστολή τους, αναζητώντας πηγές εσόδων εκτός από αυτές που διατίθενται από το κράτος. Η παρούσα μελέτη εξετάζει μια τέτοια περίπτωση, τη χρήση του επιχειρησιακού σχεδιασμού στην περιοχή Γιαννιτσών του Γενικού Νοσοκομείου Πέλλας, προκειμένου να διερευνηθούν οι ανάγκες και να δημιουργηθεί η στρατηγική ανάπτυξης του νοσοκομείου με παράλληλη αξιοποίηση εναλλακτικών και ευρωπαϊκών πηγών χρηματοδότησης.
description: Due to the financial constraints placed on the Greek state by the memoranda agreed with the creditors (European Commission, European Central Bank, International Monetary Fund), in the scope of a rescue program for the Greek economy, public spending on hospitals has been reduced as of late. It is essential to use contemporary management methods, such strategic planning, in the current day when the economic crisis is followed by a crisis in the health system caused by the development of the SARS-Cov-2 pandemic. Through this, public hospitals' actions are guided in a disciplined and methodical manner so that they can preserve their entity, grow their capacity, and fulfill their mission by looking into sources of income other than those available from the government. This study examines one such instance, the use of operational planning in the Yannitsa District of the General Hospital of Pella, in order to investigate the needs and create the hospital's development strategy while utilizing alternative and European financing sources.

Effects of the Iceland plume on Greenland's lithosphere: New insights from ambient noise tomography

Publisher: name: Elsevier B.V.
Year: 2018

description: Ambient noise tomography is used to image Greenland's lithosphere, which passed over the Iceland plume between ∼70 and ∼40 Ma. Cross-correlations from 21 stations from GLISN seismic network were used to invert for 2-D Rayleigh wave phase velocity maps for 14 periods between 8 and 40 s. We find that Rayleigh wave phase velocities substantially vary across Greenland, with slow velocities coinciding with NW-SE trending Iceland plume track. In east Greenland the detected velocity reduction at longer periods (33–40s) reflects substantially thinned lithosphere, thermally ablated by the plume. From the east, the reduced velocities shift NW at shorter periods (12–20s), indicating shallowing of the plume-related slow anomaly. In north-central Greenland, the reduced velocities appear in the proximity of the plume ∼60 Ma, reflecting lithospheric weakening in the presence of residual heat that still persists within the lithosphere. Our results provide important new constraints on variations in the seismic velocity structure of Greenland's crust and uppermost mantle, revealing prolonged effects of the mantle plume on the overpassing craton.

description: The European Lead Factory (ELF) is a pan-European public-private partnership established in 2013 and funded by the Innovative Medicines Initiative (IMI). It developed infrastructure and expertise for research teams to perform high-throughput screens to investigate which chemical compounds work best on specified drug targets. A chemical library, built within the IMI-funded ELF project, was designed to be easily shared between the ELF partners, selected academics and small and medium-sized biotech companies throughout Europe. The library consists of over 535,000 compounds that can serve as starting points for the development of new small molecule therapeutics. A FAIRplus squad team, consisting of members of both the ELF and FAIRplus projects, was tasked with investigating what would be necessary to make this unique ELF resource more FAIR, thus making it more valuable for others if and when the compound library is made available to the wider scientific community.

description: Recent work in deploying infrasound (low-frequency sound) sensors on aerostats and free-flying balloons has shown them to be viable alternatives to ground stations. However, no study to date has compared the performance of surface and freefloating infrasound microbarometers with respect to acoustic events at regional (100s of kilometers) range. The prospect of enhanced detection of aerial explosions at similar ranges, such as those from bolides, has not been investigated either. We examined infrasound signals from three 1-ton trinitrotoluene (TNT) equivalent chemical explosions using microbarometers on two separate balloons at 280- to 400-km ranges and ground stations at 6.3- to 350-km ranges. Signal celerities were consistent with acoustic waves traveling in the stratospheric duct. However, significant differences were noted between the observed arrival patterns and those predicted by an acoustic propagation model. Very low-background noise levels on the balloons were consistent with previous studies that suggest wind interference is minimal on freely drifting sensors. Simulated propagation patterns and observed noise levels also confirm that balloon-borne microbarometers should be very effective at detecting explosions in the middle and upper atmosphere as well as those on the surface.

description: Secure spectrum auctions can revolutionize the spectrum utilization of cellular networks and satisfy the ever increasing demand for resources. In this paper, a multi-tier dynamic spectrum sharing system is studied for efficient sharing of spectrum with commercial wireless system providers (WSPs), with an emphasis on federal spectrum sharing. The proposed spectrum sharing system optimizes usage of spectrum resources, manages intra-WSP and inter-WSP interference and provides essential level of security, privacy, and obfuscation to enable the most efficient and reliable usage of the shared spectrum. It features an intermediate spectrum auctioneer responsible for allocating resources to commercial WSPs by running secure spectrum auctions. The proposed secure spectrum auction, MTSSA, leverages Paillier cryptosystem to avoid possible fraud and bid-rigging. Numerical simulations are provided to compare the performance of MTSSA, in the considered spectrum sharing system, with other spectrum auction mechanisms for realistic cellular systems.

description: We present the fully relativistic multi-reference configuration interaction calculations of the ground and low-lying excited electronic states of IrO for individual spin-orbit component. The lowest states for four spin-orbit components 1/2, 3/2, 5/2, and 7/2 are calculated intensively to clarify the ground state of IrO. Our calculation suggests that the ground state is of 1/2 spin-orbit component, which is highly mixed with $^4Σ^-$ and $^2Π$ states in $Λ-S$ notation. The two low-lying states of the 5/2 and 7/2 spin-orbit components are nearly degenerate with the ground state and locate only 234 and 260 cm$^{-1}$ above, respectively. The equilibrium bond length 1.712 Å\ and harmonic vibrational frequency 903 cm$^{-1}$ of the 5/2 spin-orbit component are close to the experimental measurement of 1.724 Å\ and 909 cm$^{-1}$, which suggests the 5/2 state should be the low-lying state contributed to spectra in experimental study. Moreover, the electronic states that give rise to the observed transition bands are assigned in terms of the excited energies and oscillator strengths obtained for the 5/2 and 7/2 spin-orbit components.

description: Llaima Volcano in Chile is one of the largest and most active volcanoes in the southern Andes, with over 50 eruptions since the 1600s. After years of persistent degassing, Llaima most recently erupted in a series of violent Strombolian eruptions in 2007–2009. This period had few precursory signals, which highlights the need to obtain accurate magma storage information. While petrologic advancements have been made in understanding magma degassing and crystallization trends, a comprehensive seismic study has yet to be completed. Here, we present results of a receiver function survey utilizing a dense seismic array surrounding Llaima volcano. Application of H-κ stacking and common conversion point stacking techniques reveals a new Moho estimate and two structural anomalies beneath Llaima Volcano. We interpret a low velocity zone between 8 and 13 km depth as a newly imaged magma body.

description: For a fraction of single white dwarfs with debris disks, an additional gaseous disk was discovered. Both dust and gas are thought to be created by the disruption of planetary bodies. The composition of the extrasolar planetary material can directly be analyzed in the gaseous disk component, and the disk dynamics might be accessible by investigating the temporal behavior of the Ca II infrared emission triplet, hallmark of the gas disk. We obtained new optical spectra for the first helium-dominated white dwarf for which a gas disk was discovered (Ton 345) and modeled the non-LTE spectra of viscous gas disks composed of carbon, oxygen, magnesium, silicon, sulfur, and calcium with chemical abundances typical for solar system asteroids. Iron and its possible line-blanketing effects on the model structure and spectral energy distribution was still neglected. A set of models with different radii, effective temperatures, and surface densities as well as chondritic and bulk-Earth abundances was computed and compared with the observed line profiles of the Ca II infrared triplet. Our models suggest that the Ca II emission stems from a rather narrow gas ring with a radial extent of R=0.44-0.94 Rsol, a uniform surface density Sigma=0.3 g/cm2, and an effective temperature of Teff=6000 K. The often assumed chemical mixtures derived from photospheric abundances in polluted white dwarfs - similar to a chondritic or bulk-Earth composition - produce unobserved emission lines in the model and therefore have to be altered. We do not detect any line-profile variability on timescales of hours, but we confirm the long-term trend over the past decade for the red-blue asymmetry of the double-peaked lines.

description: Aufgrund der zunehmenden Digitalisierung und Automatisierung stehen Unternehmen, sowie MitarbeiterInnen vor neuen Herausforderungen. Durch die Covid-19 Pandemie, welche im März 2020 in einem Lockdown endete und die damit verbundene Empfehlung der österreichischen Regierung, Arbeiten so gut als möglich von zu Hause aus zu verrichten, wurden neue Chancen entdeckt. Vor dieser Pandemie wurde Homeoffice von einem geringen Teil der ArbeitnehmerInnen in Österreich genutzt. Digitalisierungsprozesse verändern laufend die Arbeitswelt und es werden neue Chancen der Flexibilität entdeckt. Die Möglichkeit für flexible Arbeitsorte und Arbeitszeiten wurde damit geschaffen. Der wissenschaftliche Nutzen dieser Masterarbeit liegt darin, dass die Voraussetzungen für Mitarbeiterbindung und Mitarbeitermotivation erarbeitet werden. Der Fokus ist darauf gelegt Unternehmen die Chancen und Risiken aufzuzeigen und diese auf die Mitarbeiterbindung umzulegen. MitarbeiterInnen sollen wieder langfristig an ein Unternehmen gebunden werden, um so die Personalfluktuation zu reduzieren. Die Literaturrecherche hat ergeben, dass es in diesem Bereich noch Forschungsbedarf gibt. Die Fachliteratur wurde verwendet, um einen Interviewleitfaden für den empirischen Teil der Masterarbeit zu erstellen. Es wurden Experteninterviews durchgeführt, welche im Anschluss anhand der Inhaltsanalyse nach Kuckartz ausgewertet wurden. Die Forschungsergebnisse zeigen, dass sich die Arbeitswelt inmitten eines Veränderungsprozesses befindet. Die Flexibilisierung erstreckt sich vom Arbeitsort bis zur Arbeitszeit. Die Herausforderungen für Unternehmen liegen in den Veränderungen der Kommunikation, der Teamentwicklung, des Führungsverhaltens und der Generationen. Der Arbeitgebermarkt wurde zum Arbeitnehmermarkt. Unternehmen müssen sich künftig an die Bedürfnisse und Wünsche der ArbeitnehmerInnen anpassen, um Fachkräfte für sich gewinnen zu können. Die Bedürfnisse haben sich aufgrund des Generationenwechsel, den Wertewandel und der Flexibilisierung verändert. Die ExpertInnen beurteilen, dass Veränderungen noch stärken auf den Markt kommen und die Digitalisierung und Automatisierung weiter vorangetrieben wird. Die Anpassungen von Arbeitszeitmodellen werden in den nächsten Jahren stattfinden, um weitere Flexibilisierungen zu ermöglichen. Homeoffice wird ein fester Bestandteil der Arbeitswelt sein und nicht mehr verschwinden. Offen bleibt, wie die Zukunft der Arbeit im Detail aussehen wird und wie sich die Digitalisierung auf den Fachkräftemangel auswirkt.

description: We develop notions of twisted spinor bundle and twisted pre-quantum bundle on quasi-Hamiltonian G-spaces. The main result of this paper is that we construct a Dirac operator with index given by positive energy representation of loop group. This generalizes the quantization of Hamiltonian $G$-spaces to quasi-Hamiltonian G-spaces.

description: The aim of a Circular Economy (CE) is that products, components and materials are kept within loops at their highest value for as long as possible. Graphic representations of technical material loops such as the butterfly diagram (Ellen MacArthur Foundation, SUN, & McKinsey Center for Business and Environment, 2015) or the Value Hill (Achterberg, Hinfelaar, & Bocken, 2016), convey this central idea. They also show how CE strategies can be organized hierarchically dependent on their value capture potential. From a resource efficiency perspective, maintenance is preferable to remanufacturing, which is preferable to recycling. The paper describes the methodology of a webtool named CE Analyst, with which users are able to quantitatively estimate the potential changes to a products’ environmental footprint of a given “linear” product, when applying one or more CE strategies. The aim is to compare the effectiveness of the different CE strategies in terms of their Product Carbon Footprint and by that give users guidance in the process of designing environmentally sound circular product systems.

description: Acoustic waves with a wide range of frequencies are generated by lightning strokes during thunderstorms, including infrasonic waves (0.1 to 20 Hz). The source mechanism for these low-frequency acoustic waves is still debated, and studies have so far been limited to ground-based instruments. Here we report the first confirmed detection of lightning-generated infrasound with acoustic instruments suspended at stratospheric altitudes using a free-flying balloon. We observe high-amplitude signals generated by lightning strokes located within 100 km of the balloon as it flew over the Tasman Sea on 17 May 2016. The signals share many characteristics with waveforms recorded previously by ground-based instruments near thunderstorms. The ability to measure lightning activity with high-altitude infrasound instruments has demonstrated the potential for using these platforms to image the full acoustic wavefield in the atmosphere. Furthermore, it validates the use of these platforms for recording and characterizing infrasonic sources located beyond the detection range of ground-based instruments.
Upper Atmosphere Heating From Ocean-Generated Acoustic Wave Energy

description: Colliding sea surface waves generate the ocean microbarom, an acoustic signal that may transmit significant energy to the upper atmosphere. Previous estimates of acoustic energy flux from the ocean microbarom and mountain-wind interactions are on the order of 0.01 to 1 mW/m2, heating the thermosphere by tens of Kelvins per day. We captured upgoing ocean microbarom waves with a balloon-borne infrasound microphone; the maximum acoustic energy flux was approximately 0.05 mW/m2. This is about half the average value reported in previous ground-based microbarom observations spanning 8 years. The acoustic flux from the microbarom episode described here may have heated the thermosphere by several Kelvins per day while the source persisted. We suggest that ocean wave models could be used to parameterize acoustically generated heating of the upper atmosphere based on sea state.

description: 1. Managing non-native species in cities is often controversial because these species can support both ecosystem services and disservices. Yet, how the acceptability of non-native species management by the general public differs in relation to native species, to distance (i.e. close to residence and elsewhere) and among plants and animals is understudied. Furthermore, while values, beliefs and knowledge are often considered in this context, psychometric factors such as emotions and anthropomorphic views have received little attention. 2. We surveyed 658 residents in Berlin, Germany, to assess (i) the acceptability of management actions differing in their severity for non-native plants and animals compared to native species with similar traits, (ii) the influence of perceived distance of species (i.e. close to residence and elsewhere) and (iii) the predictive potential of psychometric (i.e. values, beliefs, self-assessed knowledge, emotions and anthropomorphism) and socio-demographic factors for this acceptability. 3. Eradication (i.e. lethal control/removal) was generally the least accepted management action, but more accepted for non-native than native species. Distance mattered for the acceptability of non-native plant management with unspecified control action the most accepted management action close to residence. 4. While values (self-transcendence and conservation) mostly explained the acceptability of doing nothing and eradication, emotions related strongly to all management actions. Beliefs were more important than self-assessed knowledge in relation to non-native species management and beliefs about non-native plants and animals were rated almost similar. Anthropomorphic views had predictive potential for plants and animals; that is, the stronger people held anthropomorphic views, the less they accepted eradication. Participants with a garden supported doing nothing with plants (native and non-native) more than without. 5. Results highlight the complexity of factors underlying the acceptability of management actions on species in cities. While values, beliefs and self-assessed knowledge are important in the context of species management, other psychometric factors add to our understanding of acceptability. We conclude that awareness about different acceptability patterns related to species management can support environmental policies on biological invasions in cities. Tailoring and implementing adequate management actions can benefit from incorporating cognitive but also affective factors of the public.

description: An inert sphere of a few meters diameter, placed in a special stable geosynchronous orbit in perpetuo, can be used for a variety of scientific experiments. Ground-based observations of such a sphere, "GeoSphere", can resolve very difficult problems in measuring the long-term solar irradiance. GeoSphere measurements will also help us understand the evolution of Earth's albedo and climate over at least the next century.
