Healthcare Activism, Marketization, and the Collective Good
No full textThis chapter engages with three key dynamics of contemporary healthcare - digitalization, marketization and individualization. It draws on several theoretical frameworks to conceptualize the notion of collective good and to consider how healthcare activism may play into defining and defending the collective good when faced with the outlined societal, economic, and scientific dynamics. Presenting contemporary examples from the Covid-19 pandemic, the chapter argues that the way activists define and defend the collective good can only fully be understood by grasping how this good is shaped by other, often more dominant, stakeholders in healthcare: governmental institutions, professional experts, scientists, and private industry – the latter being a focal point of concern for this current volume.European Commission Horizon 2020Check for published version during checkdate report - AC2021-04-28 JG: PDF replaced at author's request2021-06-04 JG: embargo removed following documentation from author/publishe

Solutions to the radiative transfer equation with GPU-accelerated Monte Carlo simulations : applied to applications such as surface recognition and determination of the optical properties of scattering media
No full textThis thesis presents the results of six research articles that use Monte Carlo simulations to model light propagation in scattering media for various applications.
In "Determination of the optical properties of three-layered turbid media in the time domain using the P₃ approximation" (S. Geiger, D. Reitzle, A. Liemert, and A. Kienle, 2019), the inverse problem of time-resolved solutions to the radiative transfer equation is investigated. Monte Carlo simulations serve as a reference for the spherical harmonics approximation. The study finds that the P₃ approximation offers a significant advantage over the diffusion approximation.
"Semianalytical solution for the transient temperature in a scattering and absorbing slab consisting of three layers heated by a light source" (D. Reitzle, S. Geiger, A. Liemert, and A. Kienle, 2021) presents and validates a semi-analytical solution for the time-dependent heat distribution in a three-layered, laterally infinite scattering and absorbing slab illuminated by an obliquely incident, collimated beam of light.
In "Solutions for single-scattered radiance in the semi-infinite medium based on radiative transport theory" (A. Liemert, S. Geiger, and A. Kienle, 2021), solutions for the single-scattered radiance in the semi-infinite medium are presented and validated against Monte Carlo simulations, showing perfect agreement.
The article "Single scattering models for radiative transfer of isotropic and cone-shaped light sources in fog" (S. Geiger, A. Liemert, D. Reitzle, M. Bijelic, A. Ramazzina, W. Ritter, F. Heide, and A. Kienle, 2023) presents improvements to the single scattering solution of the radiative transfer equation in indefinitely spaced scattering fog. Both isotropic and cone-shaped light sources are investigated. The analytical solutions demonstrate perfect agreement with the Monte Carlo simulations. The scattering phase function for both the analytical solutions and the Monte Carlo simulations accounts for the particle distribution of the fog droplets. In the examples considered, the single scattering solution serves as a very good approximation compared to the solution that includes all scattering events.
Improvements to topography reconstruction of volume scattering objects using structured light are detailed in "Improved topography reconstruction of volume scattering objects using structured light" (S. Geiger, P. Hank, and A. Kienle, 2022). We simulate light propagation inside the object and use this information to correct the phase of the structured light, taking into account the projection and detection directions. This leads to a significant improvement in the reconstructed geometry.
In "Improved topographic reconstruction of turbid media in the spatial frequency domain including the determination of the reduced scattering and absorption coefficients" (S. Geiger, P. Hank, and A. Kienle, 2023), we improve the approach to reconstruct unknown optical properties and correct the surface geometry in a single step.
In addition to these articles, we provide an introduction that motivates the use of the radiative transfer equation and GPU-accelerated Monte Carlo simulations for the applications presented

The Use of Soft Sculpting Material and its Effect on Fine Motor Skills in Preschool Children
No full textLikovno izražanje je otrokom blizu. Je dejavnost, ki jih pomirja, vznemirja, navdušuje in hkrati tudi prispeva k njihovem razvoju. Otroci na svoje izdelke gledajo na drugačen način, kot odrasli. V njihovih kreacijah lahko vidimo, kaj jim je blizu, kaj ne, česa nimajo radi in kaj obožujejo v danem momentu. V vrtcu imajo otroci veliko priložnosti za likovno izražanje. To lahko počnejo z risanjem, slikanjem, manipulirajo z različnimi materiali in ustvarjajo skozi igro. Preko svojih izkušenj sem spoznala, da strokovni kader v vrtcu otrokom ponuja več ali manj iste načine likovnega izražanja. V svojem diplomskem delu sem želela raziskati likovno področje, ki je v vrtcu manj aktualno, zato sem se odločila raziskati kiparstvo.
Kiparstvo je likovno področje, ki svoj izraz postavlja v prostor. Ker je prostor fenomen, ki ga otroci intenzivno spoznavajo v predšolski dobi, me je zanimalo ali je kiparska dejavnost ljubša deklicam ali dečkom. Rokovanje z glino in drugimi mehkimi materiali je velikega pomena tudi za razvoj fino motorike, saj ti materiali omogočajo urjenje različnih gibov. Dobra spretnost rok, zlasti prstov pa je pomembna osnova za vrsto drugih dejavnosti, ki jih otroci izvajajo. Pod drobnogled sem vzela predšolske otroke in primerjala dve starostni skupini ter oba spola. V empiričnem delu diplomske naloge sem z otroki izpeljala nekaj specifičnih aktivnosti in primerjala rezultate finomotorične spretnosti pred in po izvedbi kiparskih dejavnosti z glino. Empirični del vključuje tudi mnenja vzgojiteljev o tem, kako vidijo in udejanjajo vlogo kiparskih aktivnosti pri razvoju finomotoričnih spretnosti. Ta del sem izvedla s pomočjo spletne ankete.Artistic expression is in children\u27s nature. It\u27s a form of expression that soothes, excites them, and leaves its imprint on their development. Children look on their crafts and products differently as we do. Through their creations we can see what is close to their emotions, what they like and what they don\u27t, what troubles them at the given moment. At the pre-school they have lot of ways to express their emotions through art. They can do that by drawing, painting, playing, and manipulating with different materials. They also create through their play. During my work at pre-schools, I gathered that professional staff usually offers the children the same means of art expression. In my diploma I wanted to research the field of art that is less used than others.
Sculpture is a field of art that children acknowledge at preschool age. My question is whether girls feel closer to the field or do the boys. Handling clay, and other soft material, is a great value for fine motor skills. It affects fine motor skills. Good movement of the hands, fingers specifically, is an important base for every other activity a child does. I took preschool children under the magnifying glass and compared two age groups and both genders. In the practical part of the diploma the children participated in a few specific tasks. Then I compared their results of fine motor skills before and after sculpting activities with clay. The empiric part of the diploma includes views, comments, and opinions of preschool teachers. I wanted their view on clay activities and fine motor skill development. I gathered this information with a web questionnaire, which was online for a month

Type material. Holotype (AMS C. 402717). Paratypes (AMS C.450272, 7; AMS C.402720, 7; AMS C.402721, 1). Type locality. 238 – 183 m, SW of Cape Naturaliste, Western Australia, Australia, 33.742 °S, 114.435 °E. Etymology. Named after Patty Jansen, New South Wales, Australia, who first recognized the distinctness of the species, and for her contributions to the knowledge of Australian micromolluscs. Description. Shell trochiform globular, medium size (to 2.5 mm). Protoconch of 0.75 whorls, with flocculant sculpture, apertural varix not connected to embryonic cap, apertural margin somewhat sinusoid. Teleoconch I of 0.75 whols, 17–21 distinct axials, spiral of same strength as axial in position of selenizone. Teleoconch II of up to 2.25 whorls. Shoulder somewhat convex, approximately 75 distinct axials on last whorl, 12–18 fine spirals forming at intersection with axials minute, dull points. Base with similar sculpture as shoulder, approximately 20 somewhat stronger spirals; spirals always cords, not as shingles. Umbilicus narrow, continuously sloping with base. Selenizone at periphery, keels moderately strong, moderately elevated; slit open margins converging towards apertural rim. Aperture rounded in lower portion, suborbicular under shoulder. Differential diagnosis. Anatoma australis (Hedley, 1903: Fig. 19) from the eastern Australia has coarser sculpture on the base, particularly with a decrease in density of the spirals in the third closest to the umbilicus; adumbilical margin of adumbilical spirals usually not fully differentiated from surface giving shinglelike appearance. Anatoma tobeyoides Geiger & Jansen, 2004 from southeastern Australia lacks the protoconch varix, and on teleoconch I of less than 0.5 whorls lacks a spiral cord in the position of the selenizone. Anatoma funiculata Geiger & Jansen, 2004 from Queensland is less globular and more angular in overall shape, has a teleoconch I of approximately 0.5 whorls, and a distinct shell strand (funiculus) running into the umbilicus.

Remarks. Geiger & Jansen (2004) noted that there was no consistent difference in the eastern and western specimens of A. australis and Anatoma “SWA” of Jansen (1999). Recent re–examination of the material showed the above indicated subtle differences. Anatoma munieri (Fischer, 1862): Figure 20 Scissurella munieri Fischer October 1, 1862: 390–391, not illustrated.

Seas of China, in bottom sands (OD). Etymology. Named after E. Munier Chalmas (OD). Description and differential diagnosis. The species was recently treated by Geiger & Jansen (2004 a) as A. turbinata. Remarks. Anatoma munieri and A. turbinata are clearly synonymous. Supporting characters include the overall turreted shape of the shell, the strong constriction below the selenizone with a subsequent spiral edge, a minor spiral edge on the base 0.66 towards the umbilicus, the shell ornamentation showing a regular reticulate pattern composed of spiral and axial cord, and the open umbilicus, which slopes continuously with the base. Anatoma munieri has only one month priority over A. turbinata. The date on the first page of the issue in which Sci. munieri was described, agrees with the publication dates given by Winckworth (1936). Although the latter species name is somewhat better known, the general rule of priority should be enforced in this case. It is not possible to apply the nomen oblitum/protectum rules, because munieri has been used as a valid species after 1900. FischerPiette (1950: 69) indicated there to be a holotype and one paratype. The holotype was not specifically designated in the original description, hence, the two specimens constitute syntypes. The subsequent holotype indication can not be viewed as a lectotype designation (ICZN Art. 74.5). The specimen shown in Figure 20 A is here designated as the lectotype with the express purpose of taxon stabilization in case other nonconspecific syntypes should be located. Bandel (1991) showed an unidentified “scissurellid”, which is here identified as A. munieri. Bandel (1998: 42) referred in his discussion of Hainella pulchella (= A. pulchella: see Geiger, 2003 for discussion of generic taxa) to an illustration in his 1991 publication that illustrated the species with a specimen from Cebu. There was no specific reference to pagination, plate or figure number, and three Bandel (1991) references were used, but only one dealing with specimens from the Philippines: Bandel (1991) of this contribution. Although A. pulchella is very distinct from A. munieri, it is likely that the reference by Bandel (1998) was a lapsus calami.Published as part of Geiger, Daniel L., 2006, Eight new species of Scissurellidae and Anatomidae (Mollusca: Gastropoda: Vetigastropoda) from around the world, with discussion of two new senior synonyms, pp. 1-33 in Zootaxa 1128 on pages 24-30, DOI: 10.5281/zenodo.27335

Shell large, biconical; H 3.95 mm, W 3.97 mm; P eroded, DN 0.13–0.16 mm; shoulder with curved axial cords and 1–3 fine spiral lines; base with spiral and axial cords forming reticulate sculpture; sculpture weakens on lower third of base; aperture rounded; umbilicus closed. Distribution. Possibly tropical Indian Ocean; southern Japan, Indo-Malayan Archipelago to the Western Pacific, 49–2570 m (Geiger 2012). Remarks. The studied material mostly conforms to the description by Geiger (2012), although some specimens are larger than 3.2 mm (largest is 3.95 mm). The shoulder occasionally has three fine spiral lines instead of one to two. The density of axial cords on shoulder and base strongly increases on the last whorl of large specimens. P and T 1 are eroded in the studied material, yet T 1 appears to have only about 11 axial ribs instead of 17–20. The studied material is quite similar in its shape, sculpture and closed umbilicus to Anatoma gephyra Maxwell, 1992 from the late Eocene of New Zealand as well, but the latter has a shorter T 1 of only 0.33 whorls.Published as part of Helwerda, Renate A. & Wesselingh, Frank P., 2014, Revision of Scissurellidae, Anatomidae and Fissurellidae (Gastropoda: Vetigastropoda) from the Plio-Pleistocene of the Philippines, pp. 183-194 in Zootaxa 3838 (2) on pages 187-189, DOI: 10.11646/zootaxa.3838.2.3, http://zenodo.org/record/22906

Inner marginal teeth triangular with approximately 3–4 denticles on each side (Fig. 20 D–E); with posterior projection on upper shaft (except marginal tooth 1: Fig. 20 C: M1); outer marginal teeth spoon or paddle shaped with many fine denticles along apical edge (Fig. 20 E–F).</p> <p> <b>Differential diagnosis.</b> <i>Thieleella baxteri</i> from the northeastern Pacific has elevated lamellar axial sculpture. <i>Anatoma janetae</i> Geiger, 2006, from deep water of the eastern Pacific has a protoconch with flocculent sculpture in spiral orientation, the spiral cord on TI does not form a marked angulation, and shows a marked change of sculpture from predominant axial elements to exclusively spiral elements after 1.25 TII whorls.</p> <p> <i>Thieleella peruviana</i> from deep water off Peru, on TI has only a week spiral cord not forming an angulation on the shell’s profile, and has more (42 vs. 15) and weaker axial cords on TI.</p> <p> <b>Remarks.</b> The only specimen at hand is most likely not fully mature, because the final quarter whorl does not markedly descend along the coiling axis. The specimen is sufficiently distinct to warrant description as new, and material from that depth is unlikely to be collected in the foreseeable future. The specimen was preserved with the body in the shell, hence, was collected live in its natural deep-sea habitat.</p> <p> The radula of the species shows a thus far unknown detail, namely the posterior projection on the apical portion of the shaft of the marginal teeth from marginal tooth 2 onwards. It is comparable to the food groove known from <i>Tegula funebralis</i> (A. Adams, 1855) and Liotiidae (see Morris & Hickman 1981, Hickman & McLean 1990). The occurrence of such a food groove in thus far a single species of Anatomidae demonstrates further the by now fairly well-documented variability of the radula within Anatomidae (Geiger 2006a, Geiger & Sasaki 2008, Sasaki <i>et al</i>. in press).</p>Published as part of <i>Geiger, Daniel L. & Mclean, James H., 2010, New species and records of Scissurellidae and Anatomidae from the Americas (Mollusca: Gastropoda: Vetigastropoda), pp. 1-35 in Zootaxa 2356</i> on pages 31-33, DOI: <a href="http://zenodo.org/record/275645">10.5281/zenodo.275645</a>
