Thomas F. Kessler Collection 2001
No full textThis collection contains a one page Austrian Heritage Collection questionnaire with biographical details; accompanied by a six page memoir about growing up in Vienna,
rise of Nazism in Vienna, accounts of anti-Jewish harassment, and emigration to the USA. Mr. Kessler is an example of a baptised Christian of Jewish descent who was nevertheless
targeted by National Socialist policy. All materials are from 2001.Thomas F. Kessler was born in Vienna, Austria, on December 14, 1917 under the name Thomas Friedrich Alfred Koessler. At that time, Thomas Kessler's father was
working as an attorney and was in a partnership with his brother Felix. His father was an active member in the Social Democratic Party. Although both his parents were Jewish, they had
abandoned their faith by the time their son was born, and Thomas was baptized as a Lutheran. He considers himself a Christian. He emigrated to the USA in 1939 and served in the US

Huánuco: Playapampa, Macbride 4510 (holotype F, isotype US). Distribution and ecology: —Andes of southern Ecuador (Loja, Zamora-Chinchipe), Peru, and Bolivia. Common, forming dense colonies in cloud forests, elfin forests, or on exposed ridges at 2000–3400 m.Published as part of Gonzales, Jasivia & Kessler, Michael, 2011, A synopsis of the Neotropical species of Sticherus (Gleicheniaceae), with descriptions of nine new species, pp. 1-54 in Phytotaxa 31 on page 42, DOI: 10.11646/phytotaxa.31.1.1, http://zenodo.org/record/489464
Angle- and spin-resolved photoelectron spectroscopy of the Hg 5d10 subshell
No full textSchönhense G, Schäfers F, Heinzmann U, Kessler J. Angle- and spin-resolved photoelectron spectroscopy of the Hg 5d10 subshell. Zeitschrift für Physik A: Hadrons and Nuclei. 1982;304(1):31-40.Parameters describing electron spin polarization in Hg 5d10 subshell photoionization have been measured at rare-gas resonance wavelengths between 73.59 nm and 30.38 nm. The spin parameters as well as asymmetry parameters beta of a recent measurement are discussed in comparison with both nonrelativistic and relativistic ab initio calculations of several authors. The importance of many-electron correlations and spin-orbit coupling effects is considered. We would like to express our thanks to F. Combet Farnoux, N. Cherepkov, W. Johnson and S. Manson for useful correspondence as well as for the communication of unpublished results. This work was supported by the DFG and BMFT.

Terpsichore contacta Moguel & M. Kessler 2009, comb. nov.
No full textTerpsichore contacta (Copel.) Moguel & M. Kessler, comb. nov. Basionym:— Ctenopteris contacta Copeland (1955 [1956]: 477). Type:— BOLIVIA: Yungas, 1890, Bang 483 (holotype, US!; isotypes, B!, F, K!, N!). This species is characterised by conspicuously linear pinnae with parallel margins, leading to a pectinate aspect. Further peculiarities are the thin-chartaceous texture of the pinnae and the glabrous or one-ciliate sporangia. Terpsichore contacta is most similar to T. laxa (Presl, 1825: 23) Smith (1993: 487) but the latter has linear-deltate pinnae and abundantly ciliate sporangia. This is an epiphyte in the wet montain Yungas forests, from 1500 m to 2300 m in Peru and Bolivia.Published as part of Velázquez, Ana Laura Moguel & Kessler, Michael, 2009, Taxonomic notes on the fern species group around Terpsichore lanigera (Polypodiaceae), including the descriptions of three new species and one new variety, pp. 35-45 in Phytotaxa 2 on page 36, DOI: 10.11646/phytotaxa.2.1.6, http://zenodo.org/record/477614
Child/Computer interaction: observation in classroom setting.
No full textBackground in music education: The present study deals with an area still under-studied in the field of music education (Webster 2002), that of interactive musical systems, in an attempt to understand in what way it can affect the learning and the musical creativity of children. In particular, we chose to study young children, 3/5 years old, because at this age the problem of the interaction between child and machine takes on a fundamental role in the learning process. Imberty (2002), and Daniel Stern (1977), describe the development of young children as based on the vocal play between child and mother (lallation, baby-talk), characterised by the mechanism of repetition and variation. The point of interest is to verify what type of music development arises when this interaction takes place not between two human subjects, but rather between a child and a machine.
Background in artificial intelligence: At the Sony CSL, a system was elaborated able to produce music in the same style as the person playing the keyboard, the Continuator (Pachet 2002). This system is based on the notion of Interactive Reflective systems. The core concept of this approach is to teach powerful – but complex – musical processes indirectly by putting the user in a situation where these processes are performed not by the user, nor by the machine, but by the actual interaction between the user and the system. The ability of the system to attract and hold the attention of children can be interpreted through the theory of Flow introduced by psychologist Csikszentmihalyi (1990).
Aims: An experimental protocol has been established to observe systematically some interesting children's behaviours observed in preliminary experience. The general aim is to understand in what way the children relate to interactive musical systems, what kinds of musical behaviours are developed, and how interactive systems can be used in the educational field to stimulate creativity and the pleasure of playing.
Method: The experiment was carried out with 27 children of 3/5 years, in an Italian kindergarten. Three sessions were held once a day for 3 consecutive days. In every session, the children were asked to play in 4 different ways: just with the keyboard, with the keyboard and the Continuator, with another child, and both with another child and the Continuator. All the sessions were recorded on video. The attention span of the children was measured for each task. Two case-studies were analysed. Successively, the most interesting conducts were selected to be tested also on the other children.
Results: It was possible to observe a sort of life cycle of interaction, that move from surprise, to different phases of excitement, analytical behaviour, invention, readjustment and relaunch. The two tasks involving the system gave rise to the longest attention spans and show how most children reach a stable level of attention characterized by a strong intrinsic motivation, and by the socialization of the musical experience (join attention). The listening conducts were particularly varied and analytical.
Conclusion: The results suggest that the Continuator, or other similar interactive reflective systems, is able to develop interesting child/computer interaction, thanks above all to its ability to replicate the musical style of the child that is playing
