Academic Labor and Music Curricula

Year: 2018

description: In this paper we parse recent initiatives rethinking music curricula—in particular, those critiquing the enduring centrality of the Western art music canon—in connection to questions of academic labor and service. Many of our interlocutors ask us: “Why are conservative curricula a problem now?” The short answer is that canon-driven music curricula have always been problematic, as reflected by historical initiatives for curricular reform. However, even if the present moment in US music departments is far from unique, it does stand out in particular institutional and disciplinary ways that offer new insights into how curricular design operates and resists change. Specifically, we argue that when it comes to matters of curricular design, students of music would merit from departments thinking differently about structures of labor and academic seniority. As we discuss, contingent faculty have recently become the majority of teaching staff in higher education. Even though this labor force has a much higher representation of minority and women scholars than tenured faculty, their control over curricula is minimal. While many of these scholars channel their desire for change into public-oriented initiatives and other forms of curriculum-adjacent academic service, this work is less valued than research and teaching, and thus contributes to a self-sustaining cycle of exclusion. Intimately entwined with the histories of music disciplines, the canon remains obstinate. In response to calls for reform, it is typically only adjusted by placing similar texts and objects in play (Natvig 2002, xi) or by mobilizing the language of “diversity” to justify and nominally amend a canon-driven curriculum. From our own positions as contingent faculty, we thus argue that the relative invisibility of academic service is a curricular issue in its own Aside from this shifting, increasingly vocal, but still largely disempowered labor force, the current political moment also animates the long and tense relationship between the humanities and social movements. Since at least the presidential campaigns of 2016 that polarized the country on the issue of immigration, if not the Black Lives Matter movement (2013–) that shone a light on the deadly repercussions of systemic racism, there has been increased pressure on academia to recognize its complicity in imperial, colonial, racist, sexist, and classist social formations, as current social movements influence initiatives variously calling for critical teaching, diversity, and decolonization. We propose that music departments recognize the performative properties of curricula, and we suggest entry points to redressing the influence of coloniality and empire that undergird the institutionalization of music.

description: Much effort has been devoted to the electronic properties of relatively thick ZrTe5 crystals, focusing on their three-dimensional topological effects. Thin ZrTe5 crystals, on the other hand, were much less explored experimentally. Here we present detailed magnetotransport studies of few-layer ZrTe5 devices, in which electron-electron interactions and weak anti-localization are observed. The coexistence of the two effects manifests themselves in corroborating evidence presented in the temperature and magnetic field dependence of the resistance. Notably, the temperature-dependent phase coherence length extracted from weak anti-localization agrees with strong electron-electron scattering in the sample. Meanwhile, universal conductance fluctuations have temperature and gate voltage dependence that is similar to that of the phase coherence length. Lastly, all the transport properties in thin ZrTe5 crystals show strong two-dimensional characteristics. Our results provide new insight into the highly intricate properties of topological material ZrTe5.

description: We present an observation of the very late thermal pulse object V4334 Sgr (Sakurai's Object) with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. The emission from 5-38 microns is dominated by the still-cooling dust shell. A number of features are seen in absorption against the dust shell, which we attribute to HCN and polyyne molecules. We use these features to determine the 12C/13C ratio for the absorbing gas to be ~ 3.2 (+3.2,-1.6}; this implies that, despite the H-content of the molecules, the hydrocarbon-bearing gas must have originated in material produced in the very late thermal pulse. We see no evidence of emission lines, despite the recently-reported optical and radio observations that suggest the effective temperature of the stellar remnant is rising.

description: "Those who can, do. Those who can't, teach." So reads a familiar adage often relayed to prospective teachers. Its appeal derives from a curious discon-nect-namely, that those who teach are compelled to do so by, or even in spite of, incapacity. Usually passed along by outsiders, this observation is rarely borne out by practical application in the educational field because the most effective teaching models lead directly by example, relying upon inspiration to make lasting impressions upon students.

Simultaneous and sequential ROC analyses for diagnostic tests
Creators: name: Fang, Raymond Rui
Publisher: name: University of British Columbia
Year: 2010

description: Relative or receiver operating characteristic (ROC) analysis is a simple procedure which can be used to measure the accuracy of diagnostic tests. Diagnostic tests are often used to classify an individual as belonging to one of two populations. Based on statistical decision theory, ROC was first developed to evaluate the performance of electronic signal detection, and has been used to evaluate the accuracy of diagnostic tests. The ROC theory for evaluating one single test, or comparing individual tests is reasonably well understood. The question arises in cases where multiple tests are available as to whether some combination of the tests are better than any single one. In this paper, two ROC procedures of evaluating the aggregate performance of multiple diagnostic tests were presented, one is for evaluating simultaneous multiple diagnostic tests, and the other is for sequential diagnostic tests. These procedures are illustrated by using a breast cancer data set.
Disciplinary Movements, the Civil Rights Movement, and Charles Keil’s Urban Blues

Publisher: name: Current Musicology
Year: 2005

description: Charles Keil was in his midtwenties when he published his first book, Urban Blues (1966a), based on his master’s thesis in anthropology at the University of Chicago. In many ways, it was the summation of his experiences and encounters up to that point: a childhood in rural Connecticut where his grandfather raised pigs; a love of jazz that began with drum lessons from his uncle (an example of what colleague Steven Feld described as “white male bonding through black music” [Keil and Feld 1994:2]); undergraduate schooling at Yale that included travel to the West Indies and Nigeria; 1960s countercultural activism intensified by a relationship with Malcolm X; a tumultuous graduate school experience under the tutelage of Clifford Geertz, David Schneider, and Marshall Sahlins in anthropology, Leonard Meyer in musicology, and Alan Merriam in ethnomusicology; and finally fieldwork in the theaters, nightclubs, radio stations, recording studios, and tour buses connected to the bustling blues scene in Chicago. The appearance of Urban Blues was not revolutionary because it came from the hand of a humanist prodigy, but because Keil approached a modern, urban African American musical style with such rigor. In the current disciplinary climate of critical musicology, ethnomusicology, anthropology, and Black Studies, it is difficult to grasp that Urban Blues was not only one of the first scholarly texts based on fieldwork in urban Afro-America, but was also one of the first ethnographic monographs dedicated to an American popular music form, and was the first to eschew transcription and detailed musical-structural analysis in favor of a sociocultural approach.

description: We present a learning algorithm for training a single policy that imitates multiple gaits of a walking robot. To achieve this, we use and extend MPC-Net, which is an Imitation Learning approach guided by Model Predictive Control (MPC). The strategy of MPC-Net differs from many other approaches since its objective is to minimize the control Hamiltonian, which derives from the principle of optimality. To represent the policies, we employ a mixture-of-experts network (MEN) and observe that the performance of a policy improves if each expert of a MEN specializes in controlling exactly one mode of a hybrid system, such as a walking robot. We introduce new loss functions for single- and multi-gait policies to achieve this kind of expert selection behavior. Moreover, we benchmark our algorithm against Behavioral Cloning and the original MPC implementation on various rough terrain scenarios. We validate our approach on hardware and show that a single learned policy can replace its teacher to control multiple gaits.
The relation between general relativity and a class of Hořava gravity theories

description: Violations of Lorentz (and specifically boost) invariance can make gravity renormalizable in the ultraviolet, as initially noted by Hořava, but are increasingly constrained in the infrared. At low energies, Hořava gravity is characterized by three dimensionless couplings, $α$, $β$ and $λ$, which vanish in the general relativistic limit. Solar system and gravitational wave experiments bound two of these couplings ($α$ and $β$) to tiny values, but the third remains relatively unconstrained ($0\leqλ\lesssim 0.01-0.1$). Moreover, demanding that (slowly moving) black-hole solutions are regular away from the central singularity requires $α$ and $β$ to vanish {\it exactly}. Although a canonical constraint analysis shows that the class of khronometric theories resulting from these constraints ($α=β=0$ and $λ\neq0$) cannot be equivalent to General Relativity, even in vacuum, previous calculations of the dynamics of the solar system, binary pulsars and gravitational-wave generation show perfect agreement with General Relativity. Here, we analyze spherical collapse and compute black-hole quasinormal modes, and find again that they behave {\it exactly} as in General Relativity, as far as {\it observational} predictions are concerned. Nevertheless, we find that spherical collapse leads to the formation of a regular {\it universal} horizon, i.e. a causal boundary for signals of arbitrary propagation speeds, inside the usual event horizon for matter and tensor gravitons. Our analysis also confirms that the additional scalar degree of freedom present alongside the spin-2 graviton of General Relativity remains strongly coupled at low energies, even on curved backgrounds. These puzzling results suggest that any further bounds on Hořava gravity will probably come from cosmology.

description: Context. Europium is an almost pure r-process element, which may be useful as a reference in nucleocosmochronology. Aims. To determine the photospheric solar abundance using CO5BOLD 3-D hydrodynamical model atmospheres. Methods. Disc-centre and integrated-flux observed solar spectra are used. The europium abundance is derived from the equivalent width measurements. As a reference 1D model atmospheres have been used, in addition. Results. The europium photospheric solar abundance is 0.52 +- 0.02 in agreement with previous determinations. We also determine the photospheric isotopic fraction of Eu(151) to be 49 % +- 2.3 % from the intensity spectra and 50% +-2.3 from the flux spectra. This compares well to the the meteoritic isotopic fraction 47.8%. We explore the 3D corrections also for dwarfs and sub-giants in the temperature range ~5000 K to ~6500 K and solar and 1/10--solar metallicities and find them to be negligible for all the models investigated. Conclusions. Our photospheric Eu abundance is in good agreement with previous determinations based on 1D models. This is in line with our conclusion that 3D effects for this element are negligible in the case of the Sun.

description: Insulator-to-metal transition in Ca$_{2}$RuO$_{4}$ has drawn keen attention because of its sensitivity to various stimulation and its potential controllability. Here, we report a direct observation of Fermi surface, which emerges upon introducing excess oxygen into an insulating Ca$_{2}$RuO$_{4}$, by using angle-resolved photoemission spectroscopy. Comparison between energy distribution curves shows that the Mott insulating gap is closed by eV-scale spectral-weight transfer with excess oxygen. Momentum-space mapping exhibits two square-shaped sheets of the Fermi surface. One is a hole-like $α$ sheet around the corner of a tetragonal Brillouin zone, and the other is an electron-like $β$ sheet around the $Γ$ point. The electron occupancies of the $α$ and $β$ bands are determined to be $n_α=1.6$ and $n_β=0.6$, respectively. Our result indicates that the insulator-to-metal transition occurs selectively in $d_{xz}$ and $d_{yz}$ bands and not yet in $d_{xy}$ band. This orbital selectivity is most likely explained in terms of the energy level of $d_{xy}$, which is deeper for Ca$_{2}$RuO$_{4+δ}$ than for Ca$_{1.8}$Sr$_{0.2}$RuO$_{4}$. Consequently, we found substantial differences from the Fermi surface of other ruthenates, shedding light on a unique role of excess oxygen among the metallization methods of Ca$_{2}$RuO$_{4}$.

description: The $24^{\circ}$ N jet borders the North Tropical Belt and North Tropical Zone, and is the fastest prograde jet on Jupiter, reaching speeds above $170$ m/s. In this region, observations have shown several periodic convective plumes, likely from latent heat release from water condensation, which affect the cloud and zonal wind structure of the jet. We model this region with the Explicit Planetary hybrid-Isentropic Coordinate model using its active microphysics scheme to study the phenomenology of water and ammonia clouds within the jet region. On perturbing the atmosphere, we find that an upper tropospheric wave develops that directly influences the cloud structure within the jet. This wave travels at $\sim75$ m/s in our model, and leads to periodic chevron-shaped features in the ammonia cloud deck. These features travel with the wave speed, and are subsequently much slower than the zonal wind at the cloud deck. The cloud structure, and the slower drift rate, were both observed following the convective outbreak in this region in 2016 and 2020. We find that an upper level circulation is responsible for these cloud features in the aftermath of the convective outbursts. The comparatively slower observed drift rates of these features, relative to the wind speed of the jet, provides constraints on the vertical wind shear above the cloud tops, and we suggest that wind velocities determined from cloud tracking should correspond to a different altitude compared to the $680$ hPa pressure level. We also diagnose the convective potential of the atmosphere due to water condensation, and find that it is strongly coupled to the wave.

Two-gluon production of $ϕ$ and $η'$ mesons in proton-proton collisions at high energies

description: We discuss gluon-gluon mechanisms for production of mesons with hidden strangeness, such as $η'$ and $ϕ$ meson, in proton-proton collisions at large energies. The $g^* g^* \to η'$ and $g^* g^* \to ϕg$ mechanisms are considered only and the corresponding cross sections are calculated in the $k_t$-factorization approach. The $F_{γ^* γ^* \to η'}$ and $F_{g^* g^* \to η'}$ form factors are calculated from quark-antiquark $η'$ light-cone wave function including quark/antiquark transverse momenta. The result for two-photon transition form factor demonstrates that higher twists may survive even to large photon virtualities. The result is compared with the result of a recent leading-twist NLO analysis which uses phenomenological distribution amplitudes fitted to exclusive production of $η'$ in $e^+ e^- \to e^+ e^- η'$ reaction. We calculate transverse momentum distributions of both $η'$ and $ϕ$ mesons in proton-proton collisions for RHIC and LHC energies. The results are compared to experimental data whenever available. The results of the Lund string model are shown for comparison for $η'$ production at LHC energies. It seems that the two-gluon fusion is not the dominant mechanism for both $ϕ$ and $η'$ production, although the situation for $η'$, especially at larger energies, is less clear due to lack of experimental data.

Plasma arginine vasotocin and angiotensin II concentrations during saline acclimation in birds with salt glands
Creators: name: Zenteno Savin, Tania
Publisher: name: University of British Columbia
Year: 2010

description: Pekin ducks (Anas platyrhynchos), Canada geese (Branta canadensis) and Glaucous-winged gulls (Larus glaucescens) responded differently during acclimation to saline equivalent to full strength sea water. All species were in hydrosmotic balance until they were given 375 mM NaCl. When the birds drank 75 mM NaCl ducks transiently decreased plasma sodium concentration ([Na⁺][formula omitted]) and osmolality (Osm[formula omitted]) and increased cloacal Na⁺ excretion; geese transiently increased hematocrit (Hct), suggesting transient extracellular dehydration; and gulls increased Osm[formula omitted] (but not Hct), suggesting that their Osm[formula omitted] had been below normal when fresh water was offered. During acclimation to moderately concentrated saline, all species progressively increased plasma arginine vasotocin levels ([AVT][formula omitted]) (without concomitant increase in Osm[formula omitted]) and decreased plasma angiotensin II concentration ([Ang II][formula omitted]) without parallel changes in Hct. Following acclimation to 300 mM NaCl total body water (TBW) was increased in ducks and geese, but acclimation to 375 mM NaCl did not affect TBW in gulls. When they drank 450 mM NaCl, ducks and geese decreased body mass and increased Hct, plasma electrolyte and osmotic concentrations, [AVT][formula omitted] and [Ang II][formula omitted], indicating they were dehydrated. In contrast, saline acclimated gulls did not increase [Ang II][formula omitted] and increased [AVT][formula omitted] less than ducks or geese. Initial [AVT][formula omitted] was not significantly correlated with sex in either ducks or geese. Female ducks increased [Ang II[formula omitted] and Osm[formula omitted] less than males during exposure to 450 mM NaCl, while female geese increased [Ang II][formula omitted] more than males. Salt gland NaCl secretion and renal water retention counterbalanced NaCl ingested in low to moderately concentrated saline in ducks, geese and gulls, but not in ducks and geese drinking saline equivalent to sea water. Gulls likely maintained simultaneous, concerted function of kidneys and salt glands during high salt intake, while cloacal excretion may have decreased in the Anatidae. Based on their relative salt secreting efficiencies, plasma ionic concentrations, Osm[formula omitted] and Hct increased much more in ducks than in geese when they drank 450 mM NaCl, and remained unchanged in gulls drinking 375 mM NaCl. Release of AVT and Ang II in birds with salt glands appears to be controlled by a complicated interrelationship between volume and tonicity (threshold for release varies among species), and these (and possibly other) hormones may affect salt gland and kidney function to maintain salt and water balance.

In addition, quantum criticality of the Ohmic bath is uncovered both in the delocalized phase and at the transition point.

The role of state fluctuations is shown to be of leading order at sufficiently high temperature, applicable to actual experiments. At low temperature the low frequency energy fluctuations are the only dominant contribution.

Household Debt, Stock Market Participation, and Stock Market Returns: A Mediation Analysis
Creators: name: Moalafi, Cecilia
Publisher: name: College of Business, Law and Social Sciences, University of Derby
Year: 2023
Subjects: Household Debt, Stock Market Participation, Stock Market Returns, Fixed Effects Regression, Mediation, Causality.

description: This thesis investigates whether increases in household debt increase stock market participation, and consequently decrease stock market returns. The three-way link is investigated across the immediate, short, and medium term, income groups, and the business cycle. Furthermore, the thesis investigates whether low interest rate environments lead to an increase in the relationship between household debt, stock market participation, and consequently stock market returns.

A three-step approach to Mediation Analysis using One-way Fixed Effect (“Within” Estimation) Regression is employed on an unbalanced panel of 14 advanced and 3 emerging market economies from 2001 to 2022. The results show that there is a negative association between household debt and stock market returns in the contemporaneous and short term, which is more pronounced in developing countries, during financial crisis periods, and in high interest rate environments. Furthermore, the negative association between household debt and stock market returns is confounded, not mediated, by stock market participation in the contemporaneous term only. The confounding effect does not vary across income groups, the business cycle, or the interest rate environment. The results are robust to using stock market development as the dependent variable.

The findings disprove existing theories that purport that household debt inflates asset prices (consequently lowering returns) initially, but stress selling (debt liquidation) then follows. This study recommends that devoting resources to tracking the use of household debt will prove an inefficient use of banks’ resources. Future studies could be extended by examining how household debt could be impacted by political and economic policy uncertainty.
Review of Eric Clarke and Nicholas Cook, eds. 2004. Empirical Musicology: Methods, Aims, Prospects. Oxford and New York: Oxford University Press
Creators: name: Devaney, Johanna
Publisher: name: Current Musicology
Year: 2005

description: Empirical Musicology is a collection of articles exploring the potential for a greater integration of empirical methods into musicology and music theory. This volume is particularly timely given the increase in available personal computer power over the past ten years and the subsequent development of software that may be used to extract, analyze, and/or compile musical data. Nicholas Cook and Eric Clarke begin by asking the question, “What is empirical musicology?” and proceed to argue that in reality all musicology is empirical to some degree, in the sense that it is based in an observable reality that may be explored, explained, and generalized. The editors subsequently redefine the issue as the extent to which current musicology makes use of the methods of empirical observation, including the ways in which these observations are regulated by the discipline’s discourse and the ways in which these methods may be applied and regulated in future research. What is proposed is not so much a paradigm shift as a paradigm expansion; the empirical musicology described here applies empirical methodologies to the meaningful data already collected on a wide range of musicological topics.

Decision Analysis of Surgical Treatment Indications for Metastatic Epidural Spinal Cord Compression

description: Metastatic epidural spinal cord compression (MESCC) occurs when tumour invades the epidural space and compresses the spinal cord. Despite Level 1 evidence that surgery is the most effective treatment for MESCC, there is controversy regarding the role of surgery because of fear that patients who have a short survival will spend a large fraction of their remaining life recovering from surgery and potential complications. This controversy could be resolved by decision-analysis of MESCC treatments using quality-adjusted-life-years (QALYs). There have been two barriers to conducting decision-analysis of QALYs for MESCC: (a) lack of utility data, and (b) skepticism regarding decision-analysis. The first four research chapters in this thesis address these barriers. The final research chapter reports a decision-analysis of QALYs on the role of surgery in MESCC. Chapter 1 provides background information on the controversy regarding surgical treatment for MESCC and the rationale for each of the subsequent chapters. Chapter 2 reports a psychometric validation study of a web-based utility valuation module for MESCC. In Chapter 3, application of this module to a general population utility valuation study with a market research panel is described. In Chapter 4, the beneficial properties of Bayesian statistical analysis to minimizing “arbitrariness” in probabilistic sensitivity analysis are described in relation to prognostication for MESCC. Chapter 5 presents a strategy for simplifying and enhancing the transparency of Markov cohort simulation. Finally, the work presented in the research chapters is applied in Chapter 6 to conduct Markov cohort simulation to determine if patients with short survival derive net health-related quality-of-life benefit from surgery. Pragmatic research around barriers to decision-analysis of QALYs for MESCC was conducted to resolve the controversy regarding the role of surgery in the treatment of MESCC. Under most circumstances, MESCC patients who can ambulate prior to treatment derive net HRQoL benefit from surgery, even if prognosis is poor. Non-ambulatory patients can derive net HRQoL benefit but only if the morbidity of surgery is relatively low. It is my hope that the work used to address barriers to decision-analysis of QALYs will be disseminated and applied in other clinical problems.

description: A reformulation of the Wheeler-DeWitt equation which highlights the role of gauge-invariant three-geometry elements is presented. It is noted that the classical super-Hamiltonian of four-dimensional gravity as simplified by Ashtekar through the use of gauge potential and densitized triad variables can furthermore be succinctly expressed as a vanishing Poisson bracket involving three-geometry elements. This is discussed in the general setting of the Barbero extension of the theory with arbitrary non-vanishing value of the Immirzi parameter, and when a cosmological constant is also present. A proposed quantum constraint of density weight two which is polynomial in the basic conjugate variables is also demonstrated to correspond to a precise simple ordering of the operators, and may thus help to resolve the factor ordering ambiguity in the extrapolation from classical to quantum gravity. Alternative expression of a density weight one quantum constraint which may be more useful in the spin network context is also discussed, but this constraint is non-polynomial and is not motivated by factor ordering. The article also highlights the fact that while the volume operator has become a preeminient object in the current manifestation of loop quantum gravity, the volume element and the Chern-Simons functional can be of equal significance, and need not be mutually exclusive. Both these fundamental objects appear explicitly in the reformulation of the Wheeler-DeWitt constraint.

description: Due to their ability to reversibly absorb/desorb hydrogen without hysteresis, Pd--Au nanoalloys have been proposed as materials for hydrogen sensing. For sensing, it is important that absorption/desorption isotherms are reproducible and stable over time. A few studies have pointed to the influence of short and long range chemical order on these isotherms, but many aspects of the impact of chemical order have remained unexplored. Here, we use alloy cluster expansions to describe the thermodynamics of hydrogen in Pd--Au in a wide concentration range. We investigate how different chemical orderings, corresponding to annealing at different temperatures as well as different external pressures of hydrogen, impact the behavior of the material with focus on its hydrogen absorption/desorption isotherms. In particular, we find that a long-range ordered L1$_2$ phase is expected to form if the \ce{H2} pressure is sufficiently high. Furthermore, we construct the phase diagram at temperatures from \unit[250]{K} to \unit[500]{K}, showing that if full equilibrium is reached in the presence of hydrogen, phase separation can often be expected to occur, in stark contrast to the phase diagram in para-equilibrium. Our results explain the experimental observation that absorption/desorption isotherms in Pd--Au are often stable over time, but also reveal pitfalls for when this may not be the case.

description: Sexual selection has been proposed as a force that could help maintain the diversity of major histocompatibility complex (MHC) genes in vertebrates. Potential selective mechanisms can be divided into pre-copulatory and post-copulatory, and in both cases, the evidence for occurrence is mixed, especially in natural populations. In this study, we used a large number of parent-offspring trios that were diplotyped for MHC class II genes in a wild population of Soay sheep (Ovis aries) to examine whether there was within-trio post-copulatory selection on MHC class II genes at both the haplotypes and diplotype levels. We found there was transmission ratio distortion of one of the eight MHC class II haplotype (E) which was transmitted less than expected by fathers, and transmission ratio distortion of another haplotype (A) which was transmitted more than expected by chance to male offspring. However, in both cases, these deviations were not significant after correction for multiple tests. In addition, we did not find any evidence of post-copulatory selection at the diplotype level. These results imply that, given known parents, there is no strong post-copulatory selection on MHC class II genes in this population.

description: We present some elementary ideas to prove the following Sylvester-Gallai type theorems involving incidences between points and lines in the planes over the complex numbers and quaternions. (1) Let A and B be finite sets of at least two complex numbers each. Then there exists a line l in the complex affine plane such that l intersects AxB in exactly two points. (2) Let S be a finite noncollinear set of points in the complex affine plane. Then there exists a line l intersecting S in 2, 3, 4 or 5 points. (3) Let A and B be finite sets of at least two quaternions each. Then there exists a line l in the quaternionic affine plane such that l intersects AxB in 2, 3, 4 or 5 points. (4) Let S be a finite noncollinear set of points in the quaternionic affine plane. Then there exists a line l intersecting S in at least 2 and at most 24 points.

description: Programming robots for general purpose applications is extremely challenging due to the great diversity of end-user tasks ranging from manufacturing environments to personal homes. Recent work has focused on enabling end-users to program robots using Programming by Demonstration. However, teaching robots new actions from scratch that can be reused for unseen tasks remains a difficult challenge and is generally left up to robotic experts. We propose iRoPro, an interactive Robot Programming framework that allows end-users to teach robots new actions from scratch and reuse them with a task planner. In this work we provide a system implementation on a two-armed Baxter robot that (i) allows simultaneous teaching of low- and high-level actions by demonstration, (ii) includes a user interface for action creation with condition inference and modification, and (iii) allows creating and solving previously unseen problems using a task planner for the robot to execute in real-time. We evaluate the generalisation power of the system on six benchmark tasks and show how taught actions can be easily reused for complex tasks. We further demonstrate its usability with a user study (N=21), where users completed eight tasks to teach the robot new actions that are reused with a task planner. The study demonstrates that users with any programming level and educational background can easily learn and use the system.
