At the suggestion of the then editor of 'Studia Celtica Japonica,' Professor Toshio Doi, this bibliography lists the returns of a questionnaire sent to all scholars in Germany who were actively involved in Celtic Studies between 1980 and 1995. They were asked to list all their publications in the field of Celtic Studies, so as to allow to carry out a survey of their research activities during this period. While most scholars kindly obliged by returning their lists, there were notable exceptions who never answered the query. Regretably, the present bibliography therefore contains important gaps, which, however, may be quite telling as far as the research situation in Germany was concerned during that period.

Somewhat surprisingly, inverted ("O-down") CO adsorbates on NaCl(100) were recently observed experimentally after infrared vibrational excitation (Lau et al., Science, 2020, 367, 175-178). Here we characterize these species using periodic density functional theory and a quantum mechanical description of vibrations. We determine stationary points and minimum energy paths for CO inversion, for low (1/8 and 1/4 monolayers (ML)) and high (1 ML) coverages. Transition state theory is applied to estimate thermal rates for "C-down" to "O-down" isomerization and the reverse process. For the 1/4 ML p(1 x 1) structure, two-dimensional and three-dimensional potential energy surfaces and corresponding anharmonic vibrational eigenstates obtained from the time-independent nuclear Schrodinger equation are presented. We find (i) rather coverage-independent CO inversion energies (of about 0.08 eV or 8 kJ mol(-1) per CO) and corresponding classical activation energies for "C-down" to "O-down" isomerization (of about 0.15 eV or 14 kJ mol(-1) per CO); (ii) thermal isomerization rates at 22 K which are vanishingly small for the "C-down" to "O-down" isomerization but non-negligible for the back reaction; (iii) several "accidentally degenerate" pairs of eigenstates well below the barrier, each pair describing "C-down" to "O-down" localized states.
Der Aufsatz behandelt die Frage, in welcher Weise die Erfahrung einer Illusion und der Vollzug einer Reflexion konstitutive Merkmale der ästhetischen Erfahrung sind. Nach einem weit verbreiteten Verständnis der ästhetischen Erfahrung beschreiben der Begriff der Illusion und der Begriff der Reflexion zwei einander entgegengesetzte Akte: Mit einem Akt der Reflexion machen wir uns eine Illusion bewusst, deren Opfer wir andernfalls waren. Der Beitrag zeigt dagegen, dass im Bereich des Ästhetischen der Begriff der Reflexion keinen Akt beschreibt, der einem Akt der Illusion entgegengesetzt ist. Die Begriffe der Reflexion und Illusion beschreiben hier vielmehr einen einzigen Akt, und zwar so, dass sie hierbei einander wechselseitig erläutern.
Doping use in recreational sports is an emerging issue that has received limited attention so far in the psychological literature. The present study assessed the lifetime prevalence of controlled performance and appearance enhancing substances ( PAES), and used behavioral reasoning theory to identify the reasons for using and for avoiding using controlled PAES in young exercisers across five European countries, in the context of the "SAFE YOU" Project. Participants were 915 young amateur athletes and exercisers (M = 21.62; SD = 2.62) from Cyprus, Germany, Greece, Italy, and UK who completed an anonymous questionnaire that included measures of self-reported use of controlled PAES, as well as reasons for using and not using controlled PAES. The results of the descriptive analyses demonstrated that almost one out five exercisers in the sample had a previous experience with controlled PAES. Higher prevalence rates were found in Greece and Cyprus and lower in Italy. The most frequently reported reasons for using controlled PAES included achieving the desired results faster; pushing the self to the (physical) limits; and recovering faster after exercise/training. Furthermore, the most frequently reported reasons for not using controlled PAES involved worry about any possible adverse health effects; not feeling the need for using them; and wanting to see what can be achieved naturally without using any controlled PAES. The findings of the present study indicate that the use of controlled PAES is fast becoming a crisis in amateur sports and exercise settings and highlight the need for preventive action and concerted anti-doping education efforts.
Study 1 targets grammatical restrictions, based on a corpus of peer group conversations among adolescents. We show that noncanonical variants have the form of bare NPs with or without preposition and appear in both multilingual and monolingual speech communities, following the same syntactic and semantic patterns. While there is a quantitative advantage for the multilingual group, noncanonical variants generally constitute only a minority compared to canonical full PP[DP]. Study 2 targets usage restrictions across communicative situations, based on a corpus of elicited productions by adolescents from a multilingual urban neighbourhood. Comparisons show significantly more noncanonical local expressions in informal, peer-group situations than in formal ones for both spoken and written modes. Taken together, results indicate a selective, grammatically restricted and register-bound choice of noncanonical local expressions.
The majority of middle-age children do not meet current physical activity guidelines. There is growing evidence that adults' physical activity is partially influenced by automatic affective processes, which are derived from affective experiences with physical activity.
However, little is known about whether these processes are interrelated with children's physical activity level.
A prospective design was used to examine whether automatic affective processes assessed by an evaluative priming procedure predict physical activity of children.
Physical activity of 48 children (8.71 +/- 0.71 years; 65% girls) was measured for 1 week with activity trackers.
In a linear regression model, automatic affective processes (beta = 0.36) significantly predicted physical activity, accounting for 11.02% of variance.
These results indicate that physical-activity-related automatic affective processes are associated with children's physical activity, as has previously been found in adults.
This study emphasizes the importance of fostering positive affective experiences associated with physical activity during childhood.
Theoretische Ansätze unter den Oberbegriffen "Hierarchy" und "Scale" sind in der Ökologie seit den 1980er-Jahren entwickelt und intensiv diskutiert worden. Das wissenschaftliche Paradigma kann mit dem Begriff "Hierarchical Patch Dynamics" beschrieben werden. Obwohl auch Anwendungsbezüge diskutiert und konzipiert wurden, hat es in Deutschland bisher in der Landschaftsplanung kein größeres Echo hervorgerufen. Gleichwohl gibt es eine Reihe interessanter Anknüpfungspunkte zwischen Aussagen der ökologischen Hierarchie-Theorie und konkreten landschaftsplanerischen und naturschutzfachliceh Aufgabenstellungen. Vor diesem Hintergrund werden Grundzüge dieser Theorie bzw. der unter dem Dach des Paradigmas "Hierarchical Patch Dynamics" versammelten theoretischen Ansätze dargestellt. Wesentlich ist die erkenntnistheoretische Grundhaltung, die versucht, unzulässige Verallgemeinerungen oder Absolutheitsansprüche auszuschließen, indem sie zunächst den Gegenstandsbereich der Ökologie beschreibt und analysiert. Auf dieser Grundlage werden Herangehensweisen zur Behandlung ökologischer Fragestellungen vorgeschlagen. Diese Herangehensweisen lassen sich auf landschaftsplanerische Aufgaben übertragen. Es wird gezeigt, für welche Bereiche eine solche Übertragung denkbar wäre. Letztlich bedürfte es einer Praxisüberprüfung, um herauszufinden, ob mit Hilfe von Ansätzen der ökologischen Hierarchie- Theorie die Bearbeitung planerischer Fragestellungen verbessert oder ergänzt werden könnte.
Background:
Cyberhate is a growing form of online aggression against a person or a group based on race, ethnicity, nationality, sexual orientation, gender, religion, or disability. The present study aims to examine psychometric properties of the Coping with Cyberhate Questionnaire, the prevalence of coping strategies in Spanish adolescents, differences in coping strategies based in sex, age, and victim status, and the association between coping with cyberhate and adolescents' mental well-being.
Method:
The sample consisted of 1,005 adolescents between 12 and 18 years old (Mage = 14.28 years, SD = 1.63; 51.9% girls) who completed self-report measures on coping strategies, victimization status, and mental well-being.
Results:
The results of confirmatory factor analyses showed a structure for the Coping with Cyberhate Questionnaire composed of six factors, namely Distal advice, Assertiveness, Helplessness/Selfblame, Close support, Technical coping, and Retaliation. It demonstrated acceptable internal consistency. The three most frequently endorsed coping strategies were Technical coping, Close support, and Assertiveness. In addition, lower Helplessness/Self-blame, and higher Close-support, Assertiveness, and Distal advice were significantly related to adolescents' better mental well-being.
Conclusion:
Prevention programs that educate adolescents about how to deal with cyberhate are needed.
The aim of this study was to develop a one-step synthesis of gold nanotriangles (NTs) in the presence of mixed phospholipid vesicles followed by a separation process to isolate purified NTs. Negatively charged vesicles containing AOT and phospholipids, in the absence and presence of additional reducing agents (polyampholytes, polyanions or low molecular weight compounds), were used as a template phase to form anisotropic gold nanoparticles. Upon addition of the gold chloride solution, the nucleation process is initiated and both types of particles, i.e., isotropic spherical and anisotropic gold nanotriangles, are formed simultaneously. As it was not possible to produce monodisperse nanotriangles with such a one-step procedure, the anisotropic nanoparticles needed to be separated from the spherical ones. Therefore, a new type of separation procedure using combined polyelectrolyte/micelle depletion flocculation was successfully applied. As a result of the different purification steps, a green colored aqueous dispersion was obtained containing highly purified, well-defined negatively charged flat nanocrystals with a platelet thickness of 10 nm and an edge length of about 175 nm. The NTs produce promising results in surface-enhanced Raman scattering.
Ionic liquids are well known for their high gas absorption capacity. It is shown that this is not a solvent constant, but can be enhanced by another factor of 10 by pore confinement, here of the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate (EmimOAc) in the pores of carbon materials. A matrix of four different carbon compounds with micro- and mesopores as well as with and without nitrogen doping is utilized to investigate the influence of the carbons structure on the nitrogen uptake in the pore-confined EmimOAc. In general, the absorption is most improved for IL in micropores and in nitrogen-doped carbon. This effect is so large that it is already seen in TGA and DSC experiments. Due to the low vapor pressure of the IL, standard volumetric sorption experiments can be used to quantify details of this effect. It is reasoned that it is the change of the molecular arrangement of the ions in the restricted space of the pores that creates additional free volume to host molecular nitrogen.

Alexander von Humboldt has been characterized as the second, scientific discoverer of the New World, as the last universal scientist, Aristotle of modern times, etc. However, more or less hidden in his correspondence we find certain self-characterizations which are not that well-known. Some of them are quoted and discussed in the paper. Thus, an attempt is made to answer the question why Humboldt liked to call himself "the old man from the mountains", and whether or not he found it appropriate to be called "Aristotle of our age."
