• Impact of green entrepreneurship on sustainable development: An ex-post empirical analysis

  Neumann, T. (2022). Impact of green entrepreneurship on sustainable development: An ex-post empirical analysis. Journal of Cleaner Production 37, pp. 134317-+. http://doi.org/10.1016/j.jclepro.2022.134317

  This paper contributes to the recent stream of econometric entrepreneurship research by introducing the environmental orientation of new ventures as a key factor for sustainable development. It empirically assesses whether relationships exist between national shares of green entrepreneurial activity (GEA) and economic, social, and environmental development. Theory and first empirical evidence suggest that – compared to conventional new ventures – new green ventures have a more positive economic and social impact and are less harmful or even beneficial to environmental quality. OLS regressions were estimated to empirically test the impact of GEA rates (share of total entrepreneurial activity) on GDP, the modified HDI, and CO₂ emissions. For this purpose, Global Entrepreneurship Monitor data for 11,909 early-stage entrepreneurs was aggregated to the macro-level of 53 countries and merged with further international datasets. The results confirmed that higher shares of GEA are positively related to economic and social development but not to environmental development. Additional tests proved the robustness of the results for different economic development levels, time-lag variations, and different measurements of dependent and independent variables. The identified economic and social importance of GEA warrants intensified policy efforts to support the discovery, creation, and exploitation of green business opportunities. Potential explanations for the counterintuitive non-significant environmental impact are discussed, leading to new research avenues.

• Care Teams Misunderstand What Most Upsets Patients About Their Care

  Conner, A. L., Podtschaske, B., Mazza, M. C., Zionts, D. L., Malcolm, E. J., Thomson, C. C., … Milstein, A. (2022). Care Teams Misunderstand What Most Upsets Patients About Their Care.

  Background: Negative healthcare delivery experiences can cause lasting patient distress and medical service misuse and disuse. Yet no multi-site study has examined whether care-team members understand what most upsets patients about their care.
  Methods: We interviewed 373 patients and 360 care-team members in the medical oncology and ambulatory surgery clinics of 11 major healthcare organizations across six U.S. census regions. Patients deeply upset by a service-related experience (n = 99, 27%) answered questions about that experience, while care-team members (n = 360) answered questions about their beliefs regarding what most upsets patients. We performed content analysis to identify memorably upsetting care (MUC) themes; a generalized estimating equation to explore whether MUC theme mention frequencies varied by participant role (care-team member vs. patient), specialty (oncology vs. surgery), facility (academic vs. community), and gender; and logistic regressions to investigate the effects of participant characteristics on individual themes.
  Results: MUC themes included three systems issues (inefficiencies, access barriers, and facilities problems) and four care-team issues (miscommunication, neglect, coldness, and incompetence). MUC theme frequencies differed by role (all Ps < 0.001), with more patients mentioning care-team coldness (OR = 0.37; 95% CI, 0.23-0.60) and incompetence (OR = 0.17; 95% CI, 0.09-0.31); but more care-team members mentioning system inefficiencies (OR = 7.01; 95% CI, 4.31-11.40) and access barriers (OR, 5.48; 95% CI, 2.81-10.69).
  Conclusions: When considering which service experiences most upset patients, care-team members underestimate the impact of their own behaviors and overestimate the impact of systems issues.
  Implications: Healthcare systems should reconsider how they collect, interpret, disseminate, and respond to patient service reports.

• Precise calculation of the W boson pole mass beyond the standard model with FlexibleSUSY

  Athron, P., Bach, M., Jacob, D. H. J., Kotlarski, W., Stöckinger, D., & Voigt, A. (2022). Precise calculation of the W boson pole mass beyond the standard model with FlexibleSUSY. Physical Review D, 106(9), 14. http://doi.org/10.1103/PhysRevD.106.095023 (Original work published November 2022)

  We present an updated calculation of the W boson pole mass in models beyond the standard model with FlexibleSUSY. The calculation has a decoupling behavior and allows for a precise W-pole mass prediction up to large new physics scales. We apply the calculation to several standard model extensions, including the MRSSM where we show that it can be compatible with large corrections to the W boson mass that would be needed to fit the recent 2022 CDF measurement.

• Comparison of the Energetic Efficiency of Gas Separation Technologies Using the Physical Optimum by the Example of Oxygen Supply Options

  Weber, S., Volta, D., & Kuck, J. (2022). Comparison of the Energetic Efficiency of Gas Separation Technologies Using the Physical Optimum by the Example of Oxygen Supply Options. Energies, Energies 15(5), 22. http://doi.org/https://doi.org/10.3390/en15051855 (Original work published März 2022)

  Abstract

  This study applies the Physical Optimum (PhO) as a reference value to rate the efficiency of two technical options for the oxygen supply of a hospital. The systematic comparison of the alternative processes using the PhO as a benchmark for the minimum input (exergy in this case) required to run a process with a certain benefit allows to determine the potential for optimization of each technology. Differences are analyzed by visualizing the losses of each individual production step in a process as well as by the resulting overall energy demand, including the primary energy. Possible alternatives are purchasing liquid oxygen from a cryogenic process or the production by means of Pressure Swing Adsorption (PSA) on site. The cryogenic production shows a lower exergy demand even though it also has a higher potential for optimization. Yet, the total losses, significantly impacted by the unavoidable transportation, sum up, resulting in the conclusion that the PSA is the preferable option overall, considering energy aspects. Finally, additional criteria such as economic, legal, and structural consequences of the respective choices are briefly outlined.

• Two-loop prediction of the anomalous magnetic moment of the muon in the Two-Higgs Doublet Model with GM2Calc 2

  Athron, P., Balazs, C., Cherchiglia, A., Jacob, D. H. J., Stöckinger, D., Stöckinger-Kim, H., & Voigt, A. (2022). Two-loop prediction of the anomalous magnetic moment of the muon in the Two-Higgs Doublet Model with GM2Calc 2. The European Physical Journal C, 82, 31. http://doi.org/10.1140/epjc/s10052-022-10148-9 (Original work published März 2022)

  Abstract

  We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment (a_μ^BSM) in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is one of the simplest and most popular extensions of the Standard Model. It is one of the few single field extensions that can give large contributions to a_μ^BSM. It is essential to include two-loop corrections to explain the long standing discrepancy between the Standard Model prediction and the experimental measurement in the Two-Higgs Doublet Model. The new version GM2Calc 2 implements the state of the art two-loop calculation for the general, flavour violating Two-Higgs Doublet Model as well as for the flavour aligned Two-Higgs Doublet Model and the type I, II, X and Y flavour conserving variants. Input parameters can be provided in either the gauge basis or the mass basis, and we provide an easy to use SLHA-like command-line interface to specify these. Using this interface users may also select between Two-Higgs Doublet Model types and choose which contributions to apply. In addition, GM2Calc 2 also provides interfaces in C++, C, Python and Mathematica, to make it easy to interface with other codes.

• Potential of Onshore Wind Turbine Inertia in Decarbonising the Future Irish Energy System

  Thiesen, H., & Jauch, C. (2022). Potential of Onshore Wind Turbine Inertia in Decarbonising the Future Irish Energy System. Applied Sciences, 12(6), 16. http://doi.org/10.3390/app12062984 (Original work published März 2021)

  Abstract

  Power system inertia is an essential part for grid frequency stability and decreases due to the replacement of fossil fuel fired power plants with variable renewable energy sources. This development is not represented sufficiently in unit commitment and economic dispatch models. If considered at all, only synchronous inertia from fossil fuel driven power plants is modelled. This results in increased CO2 emissions, curtailed renewable energy and high system costs. While wind turbines are a source for synthetic inertia and an important renewable energy source, their capability to provide inertia is not incorporated into energy system models. The work at hand closes this research gap and applies a methodology to depict synthetic inertia provided by wind turbines as part of the optimisation dispatch model. A unit commitment and economic inertia dispatch model of the the all-Island Irish power system is created. The potential of wind inertia is analysed and quantified by assessing CO2 emissions, curtailed renewable energy and system costs. Results show that synthetic inertia provided by wind turbines can save up 30.99% of the CO2 emissions, reduce curtailment by up to 39.90% and reduce system costs by 32.72%.

• FlexibleDecay: An automated calculator of scalar decay widths

  Athron, P., Büchner, A., Harries, D., Kotlarski, W., Stöckinger, D., & Voigt, A. (2022). FlexibleDecay: An automated calculator of scalar decay widths. Computer Physics Communications, 283, 27. http://doi.org/https://doi.org/10.1016/j.cpc.2022.108584 (Original work published Februar 2023)

  We present FlexibleDecay, a tool to calculate decays of scalars in a broad class of BSM models. The tool aims for high precision particularly in the case of Higgs boson decays. In the case of scalar and pseudoscalar Higgs boson decays the known higher order SM QED, QCD and EW effects are taken into account where possible. The program works in a modified MS scheme that exhibits a decoupling property with respect to heavy BSM physics, with BSM parameters themselves treated in the MS/DR-scheme allowing for an easy connection to high scale tests for, e.g., perturbativity and vacuum stability, and the many observable calculations readily available in MS/DR programs. Pure BSM effects are taken into account at the leading order, including all one-loop contributions to loop-induced processes. The program is implemented as an extension to FlexibleSUSY, which determines the mass spectrum for arbitrary BSM models, and does not require any extra configuration from the user. We compare our predictions for Higgs decays in the SM, singlet extended SM, type II THDM, CMSSM and MRSSM, as well as for squark decays in the CMSSM against a selection of publicly available tools. The numerical differences between our and other programs are explained. The release of FlexibleDecay officially deprecates the old effective couplings routines in FlexibleSUSY.
