description: The Ks band differential star count of the Two Micron All Sky Survey (2MASS) is used to derive the global structure parameters of the smooth components of the Milky Way. To avoid complication introduced by other fine structures and significant extinction near and at the Galactic plane, we only consider Galactic latitude |b| > 30 degree data. The star count data is fitted with a threecomponent model: double exponential thin disk and thick disk, and a power law decay oblate halo. Using maximum likelihood the best-fit local density of thin disk is n0 = 0.030 +- 0.002 stars/pc^3. The best-fit scale-height and length of the thin disk are Hz1 = 360+-10 pc and Hr1 = 3.7+-1.0 kpc, and those of the thick disk are and Hz2 = 1020+-30 pc and Hr2 = 5.0+-1.0 kpc, the local thick-to-thin disk density ratio is f2 = 7+-1%. The best-fit axis ratio, power law index and local density ratio of the oblate halo are kappa = 0.55+-0.15, p = 2.6+-0.6 and fh = 0.20+-0:10%, respectively. Moreover, we find some degeneracy among the key parameters (e.g. n0,Hz1, f2 and Hz2). Any pair of these parameters are anticorrelated to each other. The 2MASS data can be well-fitted by several possible combinations of parameters. This is probably the reason that there is a wide range of values for the structure parameters in literature similar to this study. Since only medium and high Galactic latitude data are analyzed, the fitting is very insensitive to the scale-lengths of the disks.

description: The variation of the dimensionless fundamental physical constant mu = m_p/m_e (the proton to electron mass ratio) can be constrained via observation of Lyman and Werner lines of molecular hydrogen in the spectra of damped Lyman alpha systems (DLAs) in the line of sight to distant QSOs. Drawing on VLT-UVES high resolution data sets of QSO 0347-383 and its DLA obtained in 2009 our analysis yields dmu/mu = (4.3 +/- 7.2) * 10^-6 at z_abs =3.025. We apply corrections for the observed offsets between discrete spectra and for the first time we find indications for inter-order distortions. Current analyses tend to underestimate the impact of systematic errors. Based on the scatter of the measured redshifts and the corresponding low significance of the redshift-sensitivity correlation we estimate the limit of accuracy of line position measurements to about 220 m/s, consisting of roughly 150 m/s due to the uncertainty of the absorption line fit and about 150 m/s allocated to systematics related to instrumentation and calibration.

description: Two-way relaying promises considerable improvements on spectral efficiency in wireless relay networks. While most existing works focus on physical layer approaches to exploit its capacity gain, the benefits of two-way relaying on upper layers are much less investigated. In this paper, we study the cross-layer design and optimization for delay quality-of-service (QoS) provisioning in two-way relay systems. Our goal is to find the optimal transmission policy to maximize the weighted sum throughput of the two users in the physical layer while guaranteeing the individual statistical delay-QoS requirement for each user in the datalink layer. This statistical delay-QoS requirement is characterized by the QoS exponent. By integrating the concept of effective capacity, the cross-layer optimization problem is equivalent to a weighted sum effective capacity maximization problem. We derive the jointly optimal power and rate adaptation policies for both three-phase and two-phase two-way relay protocols. Numerical results show that the proposed adaptive transmission policies can efficiently provide QoS guarantees and improve the performance. In addition, the throughput gain obtained by the considered three-phase and two-phase protocols over direct transmission is significant when the delay-QoS requirements are loose, but the gain diminishes at tight delay requirements. It is also found that, in the two-phase protocol, the relay node should be placed closer to the source with more stringent delay requirement.

Subjects: Research Data, Data Quality, Research Integrity, Reproducibility, Open Science

description: Regardless of the field of study, sharing data is one of the most fundamental aspects of maintaining the integrity of research. The availability of research data plays a vital role in ensuring reproducibility and the ongoing development of Open Science. A lot of progress has been made in the last years by the entire scholarly ecosystem. Nearly 100 million data citations are tracked, and thousands of repositories have adopted data citation best practices. An equal number of journals have adopted data policies, introduced data availability statements, and have established persistent links between articles and datasets. Data Management Plans are increasingly used, and institutes are supporting researchers with data software tools, data stewards, and with launching institutional data repositories. In the process, the challenges of how to collect, share and present data to a range of audiences must be integrated with questions as to whether the data are accurate and actually address the questions researchers wish to answer. We must better understand what constitutes quality data, how it can be ensured, and the processes and roles involved. Understanding the importance of these issues emerged from group discussions at the STM Research Data Program (RDP), an initiative that strives to promote the effective sharing, linking and citing of research data alongside publications. This Research Paper has developed from desk-based research and in consultation with leading experts, all of whom are involved with aspects of data quality across scholarly communications and research. We hope this Research Paper offers a valuable perspective on the ongoing transition to data-dependent science. We also hope that our framework and the highlighted initiatives will inform current debate on how to ensure data quality.
Are stewardship and valuation usefulness compatible or alternative objectives of financial accounting?

description: In their joint framework project, the FASB and the IASB recently proposed dropping stewardship as a separate objective of financial accounting, because the Boards view stewardship and valuation usefulness as compatible sub-objectives ranking under an overall objective of decision usefulness. This paper puts this conjecture to an empirical test. As it is widely agreed that asymmetric timely earnings increase the contractual efficiency of accounting information, I first test whether firms with more asymmetric timely earnings produce more valuation-useful financial accounting information. Second, I test whether firms with more influential non-equity stakeholders provide more valuation-useful financial accounting information. As non-equity stakeholders in general face higher transaction costs when diversifying unsystematic risk compared to equity stakeholders and as stewardship-related risks should be at least in part unsystematic, I expect the demand for stewardship-related accounting information to increase with the influence of non-equity stakeholders. Using a broad sample of U.S. firms and a set of firm-specific metrics for valuation usefulness based on short-window capital market reactions to quarterly earnings announcements, I document that the valuation usefulness of financial accounting information is consistently negatively related to its stewardshiporientation. I conclude from these analyses that valuation usefulness and stewardship are alternative objectives of financial accounting.

description: This paper analyzes optimal foreign aid policy in a neoclassical framework with a conflict of interest between the donor and the recipient government. Aid conditionality is modelled as a limited enforceable contract. We define conditional aid policy to be self-enforcing if, at any point in time, the conditions imposed on aid funds are supportable by the threat of a permanent aid cutoff from then onward. Quantitative results show that the effectiveness of unconditional aid is low while self-enforcing conditional aid strongly stimulates the economy. However, increasing the welfare of the poor comes at high cost: to ensure aid effectiveness, less democratic political regimes receive permanently larger aid funds.

description: This study analyzes the loss potential arising from investments into CDS for a sample of large U.S. and German mutual funds. Further, it investigates whether the comments funds make on CDS use in periodic fund reports are consistent with the disclosed CDS holdings. For several funds in the U.S., the potential losses arising from selling CDS protection are almost as high as net assets, while in Germany, this potential can be even higher. Regarding the information funds provide to investors about their use of CDS, the results of the study suggest that comments on CDS contained in periodic reports are often unspecific and sometimes misleading. Thus, investors might have to analyze portfolio holdings in order to learn about the true investment behavior of funds. For instance, in Germany, funds that use more short than long CDS often state that they only use long CDS for hedging purposes. Based on the results, it seems advisable that regulators in both countries tighten rules restricting the speculative use of derivatives by funds to a reasonable level, as well as implement more standardized disclosure policies.

description: Excerpts from the report: The Western South Dakota River Basins study area, 41,657 square miles (26,660,000 acres) in 23 counties, includes the entire area in South Dakota west of the Missouri River. Five major river basins, the Grand, Moreau, Cheyenne, Bad, and White, drain almost the entire area in an easterly direction into the Missouri River. Except for the Black Hills, the topography varies from gently rolling to rolling with occasional high buttes dotting the landscape. Streams are well defined throughout most of the area. Major land uses are cropland, rangeland, pastureland, and forest land. Rangeland and pastureland, totaling 18.8 million acres, or 70 percent of the total area, are used principally for livestock grazing. Five million acres of cropland are used primarily for wheat and domestic hay. Sixty-four percent of the 2.1 million acres of forest land is in, or near, the Black Hills. The remaining 760,000 acres in the study area are agricultural land, water areas, urban areas, and transportation. The purpose of the study is to evaluate alternatives for the development of water and related land resources that will: (1) increase economic development through increased agricultural production, and (2) enhance environmental quality through conservation and improvement of the natural resources.
description: This report on the Western South Dakota River Basins is the result of a USDA cooperative study requested by the State of South Dakota, through the Water Resources Commission, the Black Hills Conservancy Sub-District, the West River Conservancy Sub-District, and the South Dakota Conservation Commission. The study was made under the authority of section 6 of Public Law 83-566, as amended, (the Watershed Protection and Flood Prevention Act).

description: Gold intercalation between the buffer layer and a graphene monolayer of epitaxial graphene on SiC(0001) leads to the formation of quasi free standing small aggregates of clusters. Angle Resolved Photoemission Spectroscopy measurements reveal that these clusters preserve the linear dispersion of the graphene quasiparticles and surprisingly increase their Fermi velocity. They also strongly modify the band structure of graphene around the Van Hove singularities (VHs) by a strong extension without charge transfer. This result gives a new insight on the role of the intercalant in the renormalization of the bare electronic band structure of graphene usually observed in Graphite and Graphene Intercalation Compounds.
Research management striving to re-invent an up-todate idea of professionalism in a post-pandemic age

description: How is going to be professionalism for RMAs in a post-pandemic era? Which skills can we expect to require following the pandemic? Following these questions, this presentation aims to define what professionalism for today’s RMAs is – consisting of qualifications, associations, professional frameworks, among others – but, above all, what we could expect this professionalism – with its set of skills and expectations - to be in a post-pandemic future. We all know that Higher Education worldwide has been experiencing a period of identity crisis and widespread criticism following the pandemic. For this reason, in a post-pandemic age to come, research managers (RMAs) could be expected to reshuffle their skills and re-invent themselves, not only to cope with an era where even professional knowledge has a limited lifespan, which was already something to expect, according to Barnett (2008); but also to create a new idea of professionalism and up-to-date skills for the times lying ahead. All this may even end up requiring the re-design of professional frameworks and qualifications so the reshuffle of what we are and know so far in today’s research management and administration. This is going to impact professional associations, our institutions and on RMAs. This is a call to action to begin re-inventing these skills as soon as we can. This presentation is meant to be theoretical, with an empirical part describing cases of skills we could expect to acquire or need. It moves from the search for a definition of RMA to explain the move from administration to management; from here, what skills we can expect to seek in the future and what idea of professionalism lies ahead for all of us.

description: The formation of protostellar disks out of molecular cloud cores is still not fully understood. Under ideal MHD conditions, the removal of angular momentum from the disk progenitor by the typically embedded magnetic field may prevent the formation of a rotationally supported disk during the main protostellar accretion phase of low mass stars. This has been known as the magnetic braking problem and the most investigated mechanism to alleviate this problem and help removing the excess of magnetic flux during the star formation process, the so called ambipolar diffusion (AD), has been shown to be not sufficient to weaken the magnetic braking at least at this stage of the disk formation. In this work, motivated by recent progress in the understanding of magnetic reconnection in turbulent environments, we appeal to the diffusion of magnetic field mediated by magnetic reconnection as an alternative mechanism for removing magnetic flux. We investigate numerically this mechanism during the later phases of the protostellar disk formation and show its high efficiency. By means 3D MHD simulations, we show that this mechanism is able to transport magnetic flux to the outskirts of the disk progenitor at time scales compatible with the collapse, allowing the formation of a rotationally supported disk around the protostar of dimensions ~100 AU. Since MHD turbulence is expected to be present in protostellar disks, this is a natural mechanism for removing magnetic flux excess and allowing the formation of these disks. This mechanism dismiss the necessity of postulating a hypothetical increase of the Ohmic resistivity as discussed in the literature. Together with our earlier work which showed that magnetic flux removal from molecular cloud cores is very efficient, this work calls for reconsidering the relative role of AD for the processes of star and planet formation.

description: East German wages have been below the West German wage level since unification. Moreover, the East-West wage gap implied by the contractual wages specified in collective wage agreements is drifting ever further apart from the wage gap in terms of effective wages. This paper looks at the role of establishment-specific factors — such as sectoral affiliation and size of the labour force — in this process. A non-parametric decomposition that has played aprominent role in the gender wage-gap literature is applied to breakdown the East-West wage gap into its constituent components. Using establishment data from the German employment statistics, the paper demonstrates that the divergence between wage agreements and effective wages is probably not a consequence of a massive escape from collective wage agreements, or the intense use of opt-out clauses in such agreements in East Germany. Rather, the shift of East Germany’s economic structure towards lower-paying types of companies has caused the lagging behind in the adjustment of wages.

description: High-dimensional regression problems which reveal dynamic behavior are typically analyzed by time propagation of a few number of factors. The inference on the whole system is then based on the low-dimensional time series analysis. Such highdimensional problems occur frequently in many different fields of science. In this paper we address the problem of inference when the factors and factor loadings are estimated by semiparametric methods. This more flexible modelling approach poses an important question: Is it justified, from inferential point of view, to base statistical inference on the estimated times series factors? We show that the difference of the inference based on the estimated time series and 'true' unobserved time series is asymptotically negligible. Our results justify fitting vector autoregressive processes to the estimated factors, which allows one to study the dynamics of the whole high-dimensional system with a low-dimensional representation. We illustrate the theory with a simulation study. Also, we apply the method to a study of the dynamic behavior of implied volatilities and discuss other possible applications in finance and economics.

description: Stock picking is the field of financial analysis that is of particular interest for many professional investors and researchers. In this study stock picking is implemented via binary classification trees. Optimal tree size is believed to be the crucial factor in forecasting performance of the trees. While there exists a standard method of tree pruning, which is based on the cost-complexity tradeoff and used in the majority of studies employing binary decision trees, this paper introduces a novel methodology of nonsymmetric tree pruning called Best Node Strategy (BNS). An important property of BNS is proven that provides an easy way to implement the search of the optimal tree size in practice. BNS is compared with the traditional pruning approach by composing two recursive portfolios out of XETRA DAX stocks. Performance forecasts for each of the stocks are provided by constructed decision trees. It is shown that BNS clearly outperforms the traditional approach according to the backtesting results and the Diebold-Mariano test for statistical significance of the performance difference between two forecasting methods.

description: We discuss the surface impedance (Z=R-iX) of a normal-metal/superconductor proximity structure taking into account the spin-dependent potential at the junction interface. Because of the spin mixing transport at the interface, odd-frequency spin-triplet s-wave Cooper pairs penetrate into the normal metal and cause the anomalous response to electromagnetic fields. At low temperature, the local impedance at a surface of the normal metal shows the nonmonotonic temperature dependence and the anomalous relation R>X. We also discuss a possibility of observing such anomalous impedance in experiments.

description: Dislocation‐tuned functionality in ceramic oxides for potential versatile applications gains increasing attention. As the widespread chemical doping suffers from poor temperature stability, dislocations in well‐controlled mesoscopic structure may be an alternative to thermally stable intrinsic doping features. To this end, the dislocation density in plastic zones introduced by cyclic Brinell indentation is considered under thermal annealing conditions. The considerably enhanced dislocation density due to thermal treatment is found to impact both microhardness and fracture toughness, albeit only to a modest degree. The mechanistic understanding centers around enhanced mobility and multiplication of the pre‐engineered dislocations at elevated temperatures driven by the residual indentation stress, as well as the strengthened interaction of point defects and dislocations at high temperature.

Subjects: subject: Geographic information science and geodesy, remote sensing, archaeology, cultural resources management.

description: This thesis is concerned with the creation and implementation of an Architectural/Archaeological information System (A/AIS) by integrating digital terrestrial photogrammetry and CAD facilities as applicable to the requirements of architects, archaeologists and civil engineers. Architects and archaeologists are involved with the measurement, analysis and recording of the historical buildings and monuments. Hard-copy photogrammetric methods supporting such analyses and documentation are well established. But the requirement to interpret, classify and quantitatively process photographs can be time consuming. Also, they have limited application and cannot be re-examined if the information desired is not directly presented and a much more challenging extraction of 3-D coordinates than in a digital photogrammetric environment. The A/AIS has been developed to the point that it can provide a precise and reliable technique for non-contact 3-D measurements. The speed of on-line data acquisition, high degree of automation and adaptability has made this technique a powerful measurement tool with a great number of applications for architectural or archaeological sites. The designed tool (A/AIS) has been successful in producing the expected results in tasks examined for St. Avit Senieur Abbey in France, Strome Castle in Scotland, Gilbert Scott Building of Glasgow University, Hunter Memorial in Glasgow University and Anobanini Rock in Iran. The goals of this research were: to extract, using digital photogrammetric digitising, 3-D coordinates of architectural/archaeological features, to identify an appropriate 3-D model, to import 3-D points/lines into an appropriate 3-D modeller, to generate 3-D objects. to design and implement a prototype architectural Information System using the above 3-D model, to compare this approach to traditional approaches of measuring and archiving required information. An assessment of the contribution of digital photogrammetry, GIS and CAD to the surveying, conservation, recording and documentation of historical buildings and cultural monuments include digital rectification and restitution, feature extraction for the creation of 3-D digital models and the computer visualisation are the focus of this research.

Dream sharing frequency: Stability over a three-year period

Year: 2020

description: Cross-sectional surveys have indicated that dream sharing frequency declines with age. However, longitudinal studies are lacking in order to differentiate between possible cohort effects and changes with age. The present analysis included 867 persons (487 women, 380 men) with a mean age of 49.79 ± 13.62 years who completed two surveys in 2014 and 2017 that included scales measuring dream sharing frequency. The findings indicate that the frequency of sharing dreams did not change over a three-year period and that inter-individual differences are quite stable. This would be in line with the life-style hypothesis of Schonbar (1965) and, thus, the previously reported decline of dream sharing frequency in cross-sectional designs very likely reflect cohort effects. It would be very interesting to study whether life events like undergoing psychotherapy or having life-changing dreams affect this stable “dream-related trait”. Moreover, it would be valuable to know how this “dream-related trait” forms during childhood/adolescence.

description: Estimating natural rate of unemployment (NAIRU) is important for understanding the joint dynamics of unemployment, inflation, and inflation expectation. However, existing literature falls short in endogenizing inflation expectation together with NAIRU in a model consistent way. We develop and estimate a structural model with forward and backward looking Phillips curve. Inflation expectation is treated as a function of state variables and we use survey data as its observations. We find out that the estimated NAIRU using our methodology tracks the unemployment process closely except for the high inflation period around 1970. Moreover, the estimated Bayesian credible sets are narrower and our model leads to better inflation and unemployment forecasts. These results suggest that monetary policy was very effective during the sample periods and there was not much room for policy improvement.
“It’s raining again” – Bad weather in a long dream series
Creators: name: Schredl, Michael
Publisher: name: International Journal of Dream Research
Year: 2020

description: The cognitive theory of dreams, proposed by Calvin Hall in 1953, postulated that dream images serve to picture conceptions the dreamer has in his or her waking life. Dream settings, like stormy weather, might reflect the dreamer’s emotionally influenced conception of the world. In a long series (N = 11,777 dreams) rain dreams (about 1.40% of the dreams) were analyzed to study how rain in dreams affect the dream ego. Although rain had an effect on the dreamer in two thirds of the dreams and is often not accompanied by explicitly mentioned emotions, the negative emotions (48 dreams) outweighed the positive ones (4 dreams) indicating that rain dreams may picture negative conceptions of the world, i.e., the emotionally negative perceptions of their world experiences. However, the large variety of topics in rain dreams also support the idea that rain in dreams might depict a variety of different world-conceptions, from obstacles in waking life to “real” danger. Future research could link rain dreams to waking life events of the dreamer, e.g., loss of a friend (cf. the song “It’s raining again” by Supertramp) and provide empirical evidence of a representative continuity – in addition to the confirmative findings regarding a thematic continuity between waking and dreaming.

description: We use Lee-Suzuki mappings and related techniques to construct effective two-body p-shell interactions and neutrinoless double-beta operators that exactly reproduce the results of large no-core-shell-model calculations of double-beta decay in nuclei with mass number A=6. We then apply the effective operators to the decay of nuclei with A=7, 8, and 10, again comparing with no-core calculations in much larger spaces. The results with the effective two-body operators are generally good. In some cases, however, they differ non-negligibly from the full no-core results, suggesting that three-body corrections to the decay operator in heavier nuclei may be important. An application of our procedure and related ideas to fp-shell nuclei such as 76Ge should be feasible within coupled-cluster theory.

description: In vitro models are cost-efficient tools to study animal gut microbiota dynamics with controlled conditions without the ethical implications of animal studies. Nevertheless, thecontinuous optimisation of in vitro models is imperative to reduce experimental bias and generatere liable data. Here, we have tested the effect of two nitrogen gassingstrategies (overlay vs sparger) on the chicken caecal microbiota composition over time using a continuous single-stage fermentation culture system.

description: Any theory invoked to explain cosmic acceleration predicts consistency relations between the expansion history, structure growth, and all related observables. Currently there exist high-quality measurements of the expansion history from Type Ia supernovae, the cosmic microwave background temperature and polarization spectra, and baryon acoustic oscillations. We can use constraints from these datasets to predict what future probes of structure growth should observe. We apply this method to predict what range of cosmic shear power spectra would be expected if we lived in a LambdaCDM universe, with or without spatial curvature, and what results would be inconsistent and therefore falsify the model. Though predictions are relaxed if one allows for an arbitrary quintessence equation of state $-1\le w(z)\le 1$, we find that any observation that rules out LambdaCDM due to excess lensing will also rule out all quintessence models, with or without early dark energy. We further explore how uncertainties in the nonlinear matter power spectrum, e.g. from approximate fitting formulas such as Halofit, warm dark matter, or baryons, impact these limits.

description: Limit order book contains comprehensive information of liquidity on bid and ask sides. We propose a Vector Functional AutoRegressive (VFAR) model to describe the dynamics of the limit order book and demand curves and utilize the fitted model to predict the joint evolution of the liquidity demand and supply curves. In the VFAR framework, we derive a closed-form maximum likelihood estimator under sieves and provide the asymptotic consistency of the estimator. In application to limit order book records of 12 stocks in NASDAQ traded from 2 Jan 2015 to 6 Mar 2015, it shows the VAR model presents a strong predictability in liquidity curves, with R2 values as high as 98.5 percent for insample estimation and 98.2 percent in out-of-sample forecast experiments. It produces accurate 5-; 25- and 50-minute forecasts, with root mean squared error as low as 0.09 to 0.58 and mean absolute percentage error as low as 0.3 to 4.5 percent.

description: We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type, is coherently coupled to the spin ensemble consisting of nitrogen-vacancy (NV) centers in a diamond crystal via a frequency-tunable superconducting resonator acting as a quantum bus. Using this circuit, we prepare arbitrary superpositions of the qubit states that we store into collective excitations of the spin ensemble and retrieve back later on into the qubit. These results constitute a first proof of concept of spin-ensemble based quantum memory for superconducting qubits.

description: This paper presents the software framework JStatCom which is geared towards the development of rich GUI clients for numerical procedures. The concept is to solve all recurring tasks with the help of reusable Java components. Optionally, one can delegate the execution of special numerical algorithms to external programs, for example Gauss or Matlab. This way it is possible to reuse an already existing code base for numerical routines written in different programming languages and to link them with the Java world. A reference application for JStatCom is the econometric software package JMulTi, which will shortly be introduced.
Empirical confirmation of creative destruction from world trade data

description: We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy follows indeed the concept of creative destruction, as proposed by J.A. Schumpeter more than half a century ago. National economies can be viewed as complex, evolving systems, driven by a stream of appearance and disappearance of goods and services. Products appear in bursts of creative cascades. We find that products systematically tend to co-appear, and that product appearances lead to massive disappearance events of existing products in the following years. The opposite - disappearances followed by periods of appearances - is not observed. This is an empirical validation of the dominance of cascading competitive replacement events on the scale of national economies, i.e. creative destruction. We find a tendency that more complex products drive out less complex ones, i.e. progress has a direction. Finally we show that the growth trajectory of a country's product output diversity can be understood by a recently proposed evolutionary model of Schumpeterian economic dynamics.

title: Ducking and Diving: An evaluation and mapping of mid-career UK actors' and performers' career sustaining strategies
Creators: name: Sparling, Steven
Publisher: name: Goldsmiths, University of London

description: This thesis evaluates and maps career-sustaining strategies of mid-career UK actors and performers through the lens of creative entrepreneurship. Using semi-structured interviewing, this micro-qualitative approach traces on a granular level the freelance pathways of working actors navigating a competitive creative market. Contributing to the literature that explores the nature and experience of freelance creative labour, this study considers how the tension between economic and artistic logics informs strategic decision making in performers’ career pursuit and how it requires both proactive and reactive actions, undertaken spatially in both acting and non-acting work environments. Building upon existing knowledge of project and network based careers, this work links theories of multiple job holding with portfolio and protean career models and their relation to sustainability and resilience, with a specific geographic focus on mid-career UK actors and performers. A key original contribution is the PRAN model, which facilitates mapping the various spheres and motivations in which performers work in each of four quadrants: Proactive Acting, Proactive Non Acting, Reactive Acting, and Reactive Non-Acting. It finds that career sustainability in a scarcity market, is derived from the ability to navigate, or duck and dive, between these different quadrants. This new knowledge assists actors in framing their choices and understanding their self-employment situation in a way that gives them a greater sense of agency over their career, and acts as a career planning and management tool. This study helps creative labour scholars to conceptualise project-based work in a scarcity environment that happens across multiple spatial markets and how that is navigated both practically and experientially by the actor.
