description: Soziale Medien sind ein Phänomen des digitalen Zeitalters. Kinder und Jugendliche nutzen dieses Medium für den sozialen Austausch untereinander. Sie leben nicht mehr nur in der analogen, sondern auch in der digitalen Welt. Damit besitzen die digitalen Welten einen höheren Stellenwert als je zuvor. Dies ist ein Zustand welcher vor zehn Jahren nur schlecht vorstellbar war. Das Ziel dieser Bachelorarbeit war es, einen Zusammenhang zwischen der Entwicklung der Kinder und Jugendlichen und den digitalen Netzwerken herzustellen und eine Untersuchung unter der Fragestellung "Welchen Stellenwert besitzen soziale Medien in der Entwicklung von Kindern und Jugendlichen" durchzuführen. Hierfür wurden die Entwicklungstheorien von Erik H. Erikson und von Georg Herbert Mead in den Kontext der digitalen sozialen Netzwerke gebracht. Die hierdurch entstandenen Theorien wurden durch Untersuchungen qualitativer Natur validiert. Die qualitative Forschung wurde mithilfe von Experteninterviews durchgeführt. Die Experten wurden zu verschiedenen Gesichtspunkten der Pädagogik, sozialen Medien und den Umgang der Kinder und Jugendlichen mit den digitalen sozialen Netzwerken befragt. Hiebrei stellte sich heraus, dass sich eine Abwanderung von den analogen Treffpunkten der Kinder und Jugendlichen in die sozialen Medien vollzieht. Das ist bedingt durch verringerten Möglichkeiten der Kinder und Jugendlichen ihren eigenen Raum innerhalb der analogen Welt zu finden. Dieser Erkenntnisgewinn wird mit den Ergebnissen verschiedener Publikationen von Manfred Spitzer und N.A. Christakis, sowie den Studien des Medienpädagogischen Forschungsverbandes Südwest vergglichen. Innerhalb dieses Vergleichs werden Parallelen und Differenzen der bereits durchgeführten Untersuchungen, mit der vorliegenden festgestellt. Es kann daher eine Einflussnahme der sozialen medien dahingehend bewerten werden, als das sie keine erweiternde, als vielmehr kompensierende Wirkung in Bezug auf die Entwicklung der Kinder und Jugendlichen einnehmen. Dieses Ergebnis zeigt die Möglichkeiten der Medienpädagogischen Ansätze und die Notwendigkeit der Weiterentwicklung dieser, damit soziale Arbeit den Kindern und Jugendlichen in ihren Entwicklungsphasen unterstützend zur Seite stehen kann.
Protein synthesis in the ovine fetus

description: To study the effect of maternal nutrition on fetal protein synthesis, isotopic kinetic studies were undertaken in which indwelling catheters were implanted in the inferior vena cava and saphenous vein of ovine fetuses as well as the jugular vein and femoral artery of ewes at 120-130 days of gestation Following a five day post surgical recovery period an 8h continuous infusion of L-[2,3,5,6-³H] or L-[U-¹⁴ C] tyrosine was made into the fetus and ewe simultaneously. An enzymatic procedure specific for L-tyrosine was used to measure the plateau specific activity in fetal and maternal plasma. Using these values the net placental transfer, endogenous production and net utilization of tyrosine by the fetus were determined employing a two pool kinetic model. For determining the fractional protein synthetic rates in individual tissues the ewes were sacrificed and the fetuses obtained by laparotomy immediately following the continuous infusion of labelled tyrosine. The effect of starvation on tyrosine transfer across the placenta and protein synthesis by the fetus was studied by repeating the above procedures in ewes starved for 48h. Values for the net placental transfer, endogenous production and net utilization of tyrosine were 5.14, 1.29 and 6.42 mmol/d/kg respectively for fetuses of fed ewes, whereas, these values were -0.29, 4.53 and 3.88 mmol/d/kg in fetuses of starved ewes. The plasma concentrations (mg%) of glucose, alpha amino nitrogen and lactate in the fed ewes were 60.18, 10.68 and 5.58 versus 43.66, 7.80 and 7.41 in starved ewes. Glucose, alpha amino nitrogen and lactate values were also seen to change in the fetus from 12.55, 13.38 and 12.98, respectively in the fed versus 8.18, 11.55 and 15.08 in fetuses of starved ewes. The fetal tyrosine net utilization values, corrected for oxidative loss of 5.2%, were used to calculate the whole body protein synthetic values. From an average tyrosine content of carcass protein of 15.71 mmol/kg, the whole body protein synthetic rates were 63 g/d/kg in the fed versus 25 g/d/kg in the starved fetuses. Fetal tissue fractional protein synthetic rates were also affected by maternal starvation. The fractional synthetic rates (%/day) for liver, kidney, lung, heart and skeletal muscle were 78%, 45%, 65%, 14% and 26% for fed versus 12%, 22%, 23%, 11% and 10%/d for the fetuses of starved ewes. The data demonstrate that maternal feed deprivation reduces protein synthesis in the fetus.

 Description. The largest specimen is 7cm large, the other 4.5cm in width. The siphonal lining is bright red, the tunic is brown-red covered with epibionts except the siphons (Fig. 18A). The tunic is thick but not hard. The body wall is colourless except the siphons which are red. The muscles (Fig. 19 B) are strong, in bundles in the main part of the body but in dense thin parallel fibres on the ventral side (Fig. 19 B). The 6 folds are high (Fig. 19 A) with up to 22 vessels, widely separated anteriorly. The gut forms a single loop (Fig. 19 B) with a narrow stomach partially covered with several hepatic diverticula. The gonads are straight, of the pyurid shape (Fig. 19 B), with lobes slightly attached to the body wall. There are no endocarps. A large cloacal velum is curved at its anterior margin.
All characters correspond well with previous descriptions, including the shape of the spinules in lamellas (Fig. 19 C) lining the internal side of the siphons. The entire external surface of the tunic appears velvety due to a dense cover of thin stick-like spinules, as seen in electron microscopy (Fig. 19 D). Spinules commonly extend on the body surface of many pyurid species but their density is exceptional here. They were probably not seen before as they cannot be seen with naked eye on this large size species.
 Pyura elongata is widely distributed in the indo-pacific. Pyura scortea Kott, 1985 is considered here as a junior synonym.

description: The extreme extinction ($A_V\sim30$\,mag) and its variation on arc-second scales towards the Galactic centre hamper the study of its stars. Their analysis is restricted to the near infrared (NIR) regime, where the extinction curve can be approximated by a broken power law. Therefore, correcting for extinction is fundamental to analyse the structure and stellar population of the central regions of our Galaxy. We aim to, (1) discuss different strategies to de-redden the photometry and check the usefulness of extinction; (2) build extinction maps for the NIR bands $JHK_s$ and make them publicly available; (3) create a de-reddened catalogue of the GALACTICNUCLEUS (GNS) survey, identifying foreground stars; and (4) perform a preliminary analysis of the de-reddened $K_s$ luminosity functions (KLFs). We used photometry from the GNS survey to create extinction maps for the whole catalogue. We took red clump (RC) and red giant stars of similar brightnesses as a reference to build the maps and de-reddened the GNS photometry. We discussed the limitations of the process and analysed non-linear effects of the de-reddening. We obtained high resolution ($\sim3''$) extinction maps with low uncertainties ($\lesssim5$\,\%) and computed average extinctions for each of the regions covered by the GNS. We checked that our maps effectively correct the differential extinction reducing the spread of the RC features by a factor of $\sim2$. We assessed the validity of the broken power law approach computing two equivalent extinction maps $A_H$ using either $JH$ and $HK_s$ photometry for the same reference stars and obtained compatible average extinctions within the uncertainties. Finally, we analysed de-reddened KLFs for different lines of sight and found that the regions belonging to the NSD contain a homogeneous stellar population that is significantly different from that in the innermost bulge regions.

description: An exact description of $π$ electrons based on the tight-binding model of graphene as an alternant, plane macromolecule is presented. The model molecule can contain an arbitrary number of benzene rings and has armchair- and zigzag-shaped edges. This suggests an instructive alternative to the most commonly used approach, where the reference is made to the honeycomb lattice periodic in its A and B sublattices. Several advantages of the macromolecule model are demonstrated. The newly derived analytical relations detail our understanding of $π$ electron nature in achiral graphene ribbons and carbon tubes and classify these structures as quantum wires.

description: It is demonstrated that a two-parameter deformed oscillator with the deformation parameters q,p such that 0 < q,p \le 1 exhibits the property of "accidental" two-fold (pairwise) energy level degeneracy of the classes E_m=E_{m+1} and E_0=E_{m}. The most general case of degeneracy of q,p-oscillators of the form E_{m+k}=E_m (with k\ge 1 for m\ge 1 or k\ge 2 for m=0) is briefly discussed.

description: New solutions of DHOST theories can be generated by applying a disformal tranformation to a known seed solution. We examine the nature of spherically symmetric solutions of DHOST gravity obtained by disforming static spherical scalar field solutions, or stealth solutions, of general relativity. It is shown that, in these cases, black hole horizons are never created by disforming a black hole seed. New DHOST solutions are then created by disforming two lesser known scalar field solutions of general relativity: Wyman's ``other'' solution and the Husain-Martinez-Nuñez one. These new solutions demonstrate that one can obtain black hole horizons, wormhole throats, or horizonless geometries by disforming non-stealth, time-dependent, seeds.

description: We investigate in some detail an alternative simulation strategy for lattice field theory based on the so-called worm algorithm introduced by Prokof'ev and Svistunov in 2001. It amounts to stochastically simulating the strong coupling expansion rather than the usual configuration sum. A detailed error analysis and an important generalization of the method are exemplified here in the simple Ising model. It allows for estimates of the two point function where in spite of exponential decay the signal to noise ratio does not degrade at large separation. Critical slowing down is practically absent. In the outlook some thoughts on the general applicability of the method are offered.

description: Many globular clusters (GCs) are known to host multiple populations distinguishable by their light-element content. Less common are GCs displaying iron abundance spreads which are seen as evidence for enrichment through core collapse supernovae (SNe). We present a simple analytical method to estimate the number of SNe required to have occurred in a GC from its metallicity and iron abundance spread. We then use this result to estimate how long star formation (SF) lasted to build the GC. We apply our method to up-to-date measurements and find that, assuming the correctness of these measurements, multiple SNe (up to $10^5$) are required in most GCs with iron abundance spreads. The number of SNe events which contributed to the enrichment of the GCs studied here is typically a factor of 10 less than the expected number of SNe in a canonical initial mass function (IMF). This indicates that gas expulsion from the forming GC occurred after the first 10 per cent of SNe exploded. We compute that for the GCs typically SF ends after only a few Myr (extending up to $\approx 30 ~\rm Myr$ in a few cases). We also discuss possible improvements of this method and especially its sensitivity to the error of iron abundance measurements of individual stars of a GC. The method presented here can quickly give an estimate for the number of SNe required to explain the iron abundance spread in a GC without the requirement of any hydrodynamical simulations.

description: We study the forced displacement of a fluid-fluid interface in a three-dimensional channel formed by two parallel solid plates. Using a Lattice-Boltzmann method, we study situations in which a slip velocity arises from diffusion effects near the contact line. The difference between the slip and channel velocities determines whether the interface advances as a meniscus or a thin film of fluid is left adhered to the plates. We find that this effect is controlled by the capillary and Peclet numbers. We estimate the crossover from a meniscus to a thin film and find good agreement with numerical results. The penetration regime is examined in the steady state. We find that the occupation fraction of the advancing finger relative to the channel thickness is controlled by the capillary number and the viscosity contrast between the fluids. For high viscosity contrast, Lattice-Boltzmann results agree with previous results. For zero viscosity contrast, we observe remarkably narrow fingers. The shape of the finger is found to be universal.

description: Let $k$ be a field of characteristic $p$, let $P$ be a finite $p$- group, where $p$ is an odd prime, and let $D(P)$ be the Dade group of endo-permutation $kP$-modules. It is known that $D(P)$ is detected via deflation--restriction by the family of all sections of $P$ which are elementary abelian of rank $\leq2$. In this paper, we improve this result by characterizing $D(P)$ as the limit (with respect to deflation--restriction maps and conjugation maps) of all groups $D(T/S)$ where $T/S$ runs through all sections of $P$ which are either elementary abelian of rank $\leq3$ or extraspecial of order $p^3$ and exponent $p$.

 Description. Agglomerated or isolated, the specimens about 20mm in length are covered with epibionts and some sedimentary particles (Fig. 18 B). The siphons are retracted when fixed and show iridescent spinules. The upper part of the body is corrugated around the apertures, smoother ventrally. Out of the tunic, the body wall is thin with strong muscles in sphincters around the siphons and radiating muscular bundles extend from them on a half dorsal part of the body. The tentacles have one order of ramifications. About 15 longitudinal vessels are on the 6 branchial folds (Fig. 20 A), and 3 to 5 between the folds. At the oesophageal entrance each vessel ends in a long papilla. The first intestinal loop is long, the second is variable but always curved (Fig. 20 B). Endocarps are present along the whole external side of the intestine. The hepatic gland consists of several lobes of dense diverticula on the thin elongated stomach. The gonads (Fig. 20 B) of the typical pyurid shape, have endocarps on their lobes. Both oviducts and sperm ducts are long and open close to each other with the anus at the cloacal aperture. The body wall is devoid of endocarps.
The needle-shaped spinules 0.15mm long are very dense (Fig. 20 D). In light microscopy (Fig. 20 C) a small bulb appears in transparency at their attachment in an extended part of the siphonal lining, which cannot be seen in electron microscopy.
This widely distributed species was previously collected in marine lakes from Palau (Monniot F. & C. 2008).

description: Leveraging hypergraph structures to model advanced processes has gained much attention over the last few years in many areas, ranging from protein-interaction in computational biology to image retrieval using machine learning. Hypergraph models can provide a more accurate representation of the underlying processes while reducing the overall number of links compared to regular representations. However, interactive visualization methods for hypergraphs and hypergraph-based models have rarely been explored or systematically analyzed. This paper reviews the existing research landscape for hypergraph and hypergraph model visualizations and assesses the currently employed techniques. We provide an overview and a categorization of proposed approaches, focusing on performance, scalability, interaction support, successful evaluation, and the ability to represent different underlying data structures, including a recent demand for a temporal representation of interaction networks and their improvements beyond graph-based methods. Lastly, we discuss the strengths and weaknesses of the approaches and give an insight into the future challenges arising in this emerging research field.

description: We discuss the possibility of observing quantum nonlocality using the so-called mode entanglement, analyzing the differences between different types of particles in this context. We first discuss the role of coherent states in such experiments, and we comment on the existence of coherent states in nature. The discussion of coherent states naturally raises questions about the role of particle statistics in this problem. Although the Pauli exclusion principle precludes coherent states with a large number of fermionic particles, we find that a large number of fermionic coherent states, each containing at most one particle, can be used to achieve the same effect as a bosonic coherent state for the purposes of this problem. The discussion of superselection rules arises naturally in this context, because their applicability to a given situation prohibits the use of coherent states. This limitation particularly affects the scenario that we propose for detecting the mode entanglement of fermionic particles.

description: The formalism of causal dynamical triangulations (CDT) provides us with a non-perturbatively defined model of quantum gravity, where the sum over histories includes only causal space-time histories. Path integrals of CDT and their continuum limits have been studied in two, three and four dimensions. Here we investigate a generalization of the two-dimensional CDT model, where the causality constraint is partially lifted by introducing weighted branching points, and demonstrate that the system can be solved analytically in the genus-zero sector.

Causal reappraisal of the quantum three box paradox

description: Quantum three box paradox is a prototypical example of some bizarre predictions for intermediate measurements made on pre- and post-selected systems. Although in principle those effects can be explained by measurement disturbance, it is not clear what mechanisms are required to fully account for the observed correlations. In this paper, this paradox is scrutinised from the causal point of view. We consider an array of potential causal structures behind the experiment, eliminating those without enough explanatory power. This gives a means of differentiating between the various mechanisms in which measurement disturbance can propagate in the system. Specifically, we distinguish whether it is just the measurement outcome or the full measurement context that is required for the causal explanation of the observed statistics. We show that the latter is indispensable, but only when the full statistics is taken into account (which includes checking the third box too). Furthermore, we discuss the realism assumption which posits the existence of preexisting values revealed by measurements. It is shown that in this case measurement disturbance is necessary. Interestingly, without the realism assumption, the original version of the paradox (with just two boxes considered for inspection) can be explained without resorting to any measurement disturbance. These various results illustrate the richness of the paradox which is better appreciated from the causal perspective.

Genetics of the immune response to ferredoxin : assessment of control at the determinant level
Creators: name: Sikora, Lydia Kazimiera Jadwiga
Publisher: name: University of British Columbia
Year: 2010

description: Ferredoxin (Fd), a fifty-five amino acid electron transport protein of the anaerobe Clostridium pasteurianum, has been chosen as the ideal probe for immunoregulation studies. Its critical feature is that it contains two antigenic determinants satisfying the hypothetical minimum requirement for immunogenicity. It was found that both the antibody (as measured by ELISA) and the lympho-proliferative responses to Fd are linked exclusively to the MHC of mice, mapping to K/I-A. Analysis of the response was undertaken at the determinant level with selective enzyme cleavage products of trypsin and carboxypeptidase A which yield respectively a 52 residue C-determinant peptide (devoid of a functional N-determinant), "C", and a 53 residue N-determinant peptide (devoid of a functional C-determinant peptide), "N",. Through the use of these two molecules ("N" and "C") and a doubly digested molecule, "M", the immune response to Fd was dissected. At first, anti-Fd antibody from high responder, H-2[sup=k], mice was shown to be 10-20% "N" specific with the balance of the response "C" directed, while intermediate responder haplotypes, H-2[sup=b] and H-2[sup=s]. demonstrate equal specificity for the two determinants. H-2 mice were uniformly non-responsive. Fd immune T-cells demonstrated lymphoproliferative capacity mirroring the antibody response of B10.BR (H-2[sup=k]) mice: "C" induced proliferation comparable to that with the native molecule, "N" inducing a much lower response, one matched by the "M" peptide. Next, the "N", "C" and "M" molecules were assessed for their immunogenicity in B10.BR, C57BL/10 (H-2[sup=b])and B10.D2 (H-2[sup=d]) mice. "N" was found to induce limited, if any, antibody production whereas it primes for a very good proliferative response (B10.BR only). "M" induced no antibody response in any strain, and minimal proliferation in B10.BR. "C" induced at least two-fold higher antibody in B10.BR and C57BL/10 as compared to native Fd, and converted the B10.D2 non-responders into responders. "C" induced a weak proliferative response in B10.BR. The data suggest that two determinants exist at the B-cell level, while three determinants account for the T-cell response.

description: A perpendicular ion drift is investigated as a mechanism for the generation of magnetic field structures in a highly collisional dusty plasma. The basic dissipation mechanism is assumed to be the dust-neutrals momentum exchange, so that plasmas with a small ionization fraction are natural candidates for experiments. The model reduces to a nonlinear partial differential equation for the vector potential. The conditions for linear instability are determined. The stationary states are periodic arrangements for the magnetic field, described by a Lienard equation. The fully depleted (ion-dust) case is also considered in detail. Applications to planetary rings, comets and dust acoustic instability experiments are analyzed. A necessary condition for the validity of the model is a sufficiently slow time-scale of the generated magnetic fields.

description: We study reheating in a recently proposed brane "monodromy inflation" model in which the inflaton is the position of a D4 brane on a "twisted torus". Specifically, we study the repeated collisions between the D4 brane and a D6 brane (on which the Standard Model fields are assumed to be localized) at a fixed position along the monodromy direction as the D4 brane rolls down its potential. We find that there is no trapping of the rolling D4 brane until it reaches the bottom of its potential, and that reheating is entirely described by the last brane encounter. Previous collisions have negligible effect on the brane velocity and hence on the reheat temperature. In the context of our setup, reheating is efficient and the reheat temperature is therefore high.

description: We consider the first-crossing-time problem through a constant boundary for a Wiener process perturbed by random jumps driven by a counting process. On the base of a sample-path analysis of the jump-diffusion process we obtain explicit lower bounds for the first-crossing-time density and for the first-crossing-time distribution function. In the case of the distribution function, the bound is improved by use of processes comparison based on the usual stochastic order. The special case of constant jumps driven by a Poisson process is thoroughly discussed.

Three-dimensional aspects of fluid flows in channels. II. Effects of Meniscus and Thin Film regimes on Viscous Fingers

description: We perform a three-dimensional study of steady state viscous fingers that develop in linear channels. By means of a three-dimensional Lattice-Boltzmann scheme that mimics the full macroscopic equations of motion of the fluid momentum and order parameter, we study the effect of the thickness of the channel in two cases. First, for total displacement of the fluids in the channel thickness direction, we find that the steady state finger is effectively two-dimensional and that previous two-dimensional results can be recovered by taking into account the effect of a curved meniscus across the channel thickness as a contribution to surface stresses. Secondly, when a thin film develops in the channel thickness direction, the finger narrows with increasing channel aspect ratio in agreement with experimental results. The effect of the thin film renders the problem three-dimensional and results deviate from the two-dimensional prediction.

description: Many practical problems need the output of a machine learning model to satisfy a set of constraints, $K$. Nevertheless, there is no known guarantee that classical neural network architectures can exactly encode constraints while simultaneously achieving universality. We provide a quantitative constrained universal approximation theorem which guarantees that for any non-convex compact set $K$ and any continuous function $f:\mathbb{R}^n\rightarrow K$, there is a probabilistic transformer $\hat{F}$ whose randomized outputs all lie in $K$ and whose expected output uniformly approximates $f$. Our second main result is a "deep neural version" of Berge's Maximum Theorem (1963). The result guarantees that given an objective function $L$, a constraint set $K$, and a family of soft constraint sets, there is a probabilistic transformer $\hat{F}$ that approximately minimizes $L$ and whose outputs belong to $K$; moreover, $\hat{F}$ approximately satisfies the soft constraints. Our results imply the first universal approximation theorem for classical transformers with exact convex constraint satisfaction. They also yield that a chart-free universal approximation theorem for Riemannian manifold-valued functions subject to suitable geodesically convex constraints.

Effects of physics beyond the standard model on the neutrino charge radius: an effective Lagrangian approach

description: In this work, we look for possible new physics effects on the electromagnetic charge and anapole form factors, $f_Q(q^2)$ and $f_A(q^2)$, for a massless Dirac neutrino, when these quantities are calculated in the context of an effective electroweak Yang-Mills theory, which induces the most general $SU_L(2)$--invariant Lorentz tensor structure of nonrenormalizable type for the $WWγ$ vertex. It is found that in this context, besides the standard model contribution, the additional contribution to $f_{Q}(q^2)$ and $f_{A}(q^2)$ ($f_{Q}^{O_W}(q^2)$ and $f_{A}^{O_W}(q^2)$, respectively) are gauge independent and finite functions of $q^2$ after adopting a renormalization scheme. These form factors, $f_{Q}^{O_W}(q^2)$ and $f_{A}^{O_W}(q^2)$, get contribution at the one loop level only from the proper neutrino electromagnetic vertex. Besides, the relation $f_{Q}^{eff}(q^2)=q^2f_{A}^{eff}(q^2)$ ($f_{Q}^{eff}(q^2)=f_{Q}^{SM}(q^2)+f_{Q}^{O_W}(q^2)$, $f_{A}^{eff}(q^2)=f_{A}^{SM}(q^2)+f_{A}^{O_W}(q^2)$) is still fulfilled and hence the relation $a_ν^{eff} = < r^2_ν > ^{eff} /6$ ($a_ν^{eff} = a_ν^{SM}+ a_ν^{O_W}$, $ ^{eff} = < r^2_ν > ^{SM}+< r^2_ν > ^{O_W}$)is gotten, just as in the SM. Using the experimental constraint on the anomalous $WWγ$ vertex, a value for the additional contribution to the charge radius of $|< r^2_ν >^{O_W}| \lsim 10^{-34} cm^2$ is obtained, which is one order of magnitude lower than the SM value.

description: Contains the supplementary material for the paper "Detecting Developers' Task Switches and Types". All contents are explained in the file README.txt.

Abstract: Developers' work on a broad variety of tasks during their days and constantly switch between tasks. While these task switches can be beneficial, they can also incur a high cognitive burden on developers, since they have to continuously remember and rebuild task context - the artifacts and applications relevant to the task. Researchers have therefore proposed to capture task context more explicitly and use this to provide better task support, such as task switch reduction or resumption support. Yet, these approaches generally require the developer to manually identify task switches. Automatic approaches for predicting task switches have so far been limited in their accuracy, scope and the time discrepancy between predicted and actual task switches.

In our work, we examine the use of automatically collected computer interaction data for detecting developers' task switches as well as task types. In two field studies--a 4h observational study and a multi-day study with experience sampling--we collected data from a total of 25 professional developers. Our study results show that we are able to use temporal and semantic features from developers' computer interaction data to detect task switches and types in the field with high accuracy of 87% and 61% respectively, and within a short time window of less than 1.6 minutes on average from the actual task switch. We discuss our findings and their practical value for a wide range of applications in real work settings.

Music as the means to an end : an inquiry into the musical content of the works of Georg Philipp Harsdörffer
Creators: name: Spence, Elizabeth Ann
Publisher: name: University of British Columbia
Year: 2010

description: The prime purpose of this inquiry is to determine the extent and significance of the treatment of music in the literary and scholarly works of the German writer, Georg Philipp Harsdorffer (1607-1658). At the same time, his references to music are also used as a means of establishing the importance of a non-literary medium for a seventeenth-century writer, and to illustrate Harsdorffer's place in the intellectual life of his times. At the outset, the lack of strict dividing lines between the arts of music and poetry, and between the arts and the sciences in the seventeenth-century is stressed, as is Harsdorffer's own view of the close relationship of all the arts and other fields of knowledge. The seventeenth-century tripartite classification of music, Musica Theoretica, Musica Practica and Musica Poetica, is used as an organizing principle to allow his statements on music to be assessed in their contemporary context. The first chapter, Musica Theoretica, dealing with music as a subject for philosophical speculation, demonstrates Harsdorffer's wide knowledge in this area and his eclectic use of sources. The second chapter, Musica Practica, concerned with music as a science and a practical art, provides information on instruments and technical musical terminology of the seventeenth-century, and shows Harsdorffer's familiarity with these. It is emphasised that his clear presentation of material here is aimed at the practical needs of readers wishing to partake in musical activities. Much of the information provided in the first two chapters is applied in the third chapter, Musica Poetica, which deals with the relationship of music and poetry. An examination of selected poems and songs shows the arts to have formal features in common. Harsdorffer's close collaboration with the composer Sigmund Staden is also established by the analysis of an extract from their opera, Seelewig, and a new source for this work is investigated for the first time. The variety of material in all three chapters is finally put into the context of universal harmony and the Christian world view.
