title: Maximizing the Effect of Shared Top Management Team Experience on Team Performance
Creators: name: Kroner, Robert
Publisher: name: Student Undergraduate Research E-journal!
Year: 2017

description: This paper examines the effects of shared top management team experience on team performance. Previous literature predicts that there could be positive or negative effects caused by team stability. For top management teams, a curvilinear relationship between shared team experience and performance is being proposed, resulting in a performance peak point. An empirical study of US-based top management teams confirmed both the positive effects and the diminishing returns, implying a maximum point after 10 years. As most firms apply changes to top management teams earlier, this study advocates practitioners to enhance team stability to exploit the team dynamic effects.

description: The spin Hall magnetoresistance (SMR) effect arises from spin-transfer processes across the interface between a spin Hall active metal and an insulating magnet. While the SMR response of ferrimagnetic and antiferromagnetic insulators has been studied extensively, the SMR of a paramagnetic spin ensemble is not well established. Thus, we investigate herein the magnetoresistive response of as-deposited yttrium iron garnet/platinum thin film bilayers as a function of the orientation and the amplitude of an externally applied magnetic field. Structural and magnetic characterization show no evidence for crystalline order or spontaneous magnetization in the yttrium iron garnet layer. Nevertheless, we observe a clear magnetoresistance response with a dependence on the magnetic field orientation characteristic for the SMR. We propose two models for the origin of the SMR response in paramagnetic insulator/Pt heterostructures. The first model describes the SMR of an ensemble of non-interacting paramagnetic moments, while the second model describes the magnetoresistance arising by considering the total net moment. Interestingly, our experimental data are consistently described by the net moment picture, in contrast to the situation in compensated ferrimagnets or antiferromagnets.

description: In the context of the field theory limit of superstrings, we consider an almost realistic model of supersymmetry breaking by gaugino condensation which includes, through nonperturbative corrections to the Kähler potential, dilaton stabilization at a value compatible with a weak coupling regime. Invariance under modular transformations is ensured through a Green-Schwarz term and string threshold corrections, which lead to moduli stabilization at the self-dual point. We are thus in a position to discuss several issues of physical relevance: gravitino, dilaton and moduli masses, axion, soft supersymmetry breaking parameters and gauge coupling unification.

Extreme velocity gradients in turbulent flows

description: Fully turbulent flows are characterized by intermittent formation of very localized and intense velocity gradients. These gradients can be orders of magnitude larger than their typical value and lead to many unique properties of turbulence. Using direct numerical simulations of the Navier-Stokes equations with unprecedented small-scale resolution, we characterize such extreme events over a significant range of turbulence intensities, parameterized by the Taylor-scale Reynolds number ($R_λ$). Remarkably, we find the strongest velocity gradients to empirically scale as $τ_K^{-1} R_λ^β$, with $β\approx 0.775 \pm 0.025$, where $τ_K$ is the Kolmogorov time scale (with its inverse, $τ_K^{-1}$, being the {r.m.s.} of velocity gradient fluctuations). Additionally, we observe velocity increments across very small distances $r \le η$, where $η$ is the Kolmogorov length scale, to be as large as the {r.m.s.} of the velocity fluctuations. Both observations suggest that the smallest length scale in the flow behaves as $ηR_λ^{-α}$, with $α= β- \frac{1}{2}$, which is at odds with predictions from existing phenomenological theories. We find that extreme gradients are arranged in vortex tubes, such that strain conditioned on vorticity grows on average slower than vorticity, approximately as a power law with an exponent $γ< 1$, which weakly increases with $R_λ$. Using scaling arguments, we get $β=(2-γ)^{-1}$, which suggests that $β$ would also slowly increase with $R_λ$. We conjecture that approaching the limit of infinite $R_λ$, the flow is overall smooth, with intense velocity gradients over scale $ ηR_λ^{-1/2}$, corresponding to $β= 1$.

The model is also consistent with observable urban growth dynamics, our results agreeing both qualitatively and quantitatively with urban data. The resulting growth morphology can be understood from interactions among the constituent units forming an urban region, and can be modeled using a correlated percolation model in the presence of a gradient.

description: The existence of many-body mobility edges in closed quantum systems has been the focus of intense debate after the emergence of the description of the many-body localization phenomenon. Here we propose that this issue can be settled in experiments by investigating the time evolution of local degrees of freedom, tailored for specific energies and initial states. An interacting model of spinless fermions with exponentially long-ranged tunneling amplitudes, whose non-interacting version known to display single-particle mobility edges, is used as the starting point upon which nearest-neighbor interactions are included. We verify the manifestation of many-body mobility edges by using numerous probes, suggesting that one cannot explain their appearance as merely being a result of finite-size effects.

description: Resumen

La rizosfera es la zona del suelo circundante y más cercano a las raíces de las plantas y contiene principalmente material rocoso, partículas de tierra de diferentes texturas, raíces, nutrientes en forma de compuestos orgánicos e inorgánicos, agua y microorganismos. 

Desde el punto de vista microbiológico, el estudio de los microorganismos rizosféricos comenzó en 1888 en las raíces de gramíneas y leguminosas, donde se observó una relación entre la fijación del nitrógeno atmosférico y las bacterias del suelo [1]. Al paso del tiempo se ha determinado que las comunidades microbianas del suelo son complejas y difíciles de estudiar debido a la gran cantidad de microorganismos y las relaciones que pueden establecerse entre la planta y ellos. La zona rizosférica puede contener nematodos, bacterias, hongos, artrópodos, herbívoros y es considerada como uno de los ecosistemas más complejos del planeta [2]. 

Un caso especial de estudio son las bacterias de la rizosfera, debido a que algunas participan en el proceso de crecimiento de las plantas. Entre los microorganismos más comunes en la rizosfera se encuentran los géneros de Pseudomonas, Bacillus, Azospirillum, Rhizobium, Stenotrophomonas, Serratia, Streptomyces, Enterobacter, Burkholderia, Acinetobacter, Paenibacillus y Arthrobacter [1-3]. 

Algunos de estos microorganismos tienen un papel muy importante en el crecimiento de las plantas, tanto que han sido llamados rizobacterias. Este término fue introducido por Kloepper y Schroth (1978) y hace referencia a la comunidad bacteriana del suelo que competitivamente coloniza las raíces de las plantas y estimula el crecimiento y, por lo tanto, reduce la incidencia de enfermedades de las plantas [1].  Algunas de estas bacterias promueven el crecimiento de las plantas al solubilizar fosfatos insolubles, fijar nitrógeno atmosférico y secretar hormonas como las fitohormonas de tipo auxinas y giberelinas [2, 4].  Aunado a esto benefician indirectamente el crecimiento de las plantas mediante resistencia sistémica inducida, la competencia por nutrientes, antibiosis, parasitismo y producción de metabolitos supresores de rizobacterias nocivas [1]. Las bacterias promotoras del crecimiento vegetal actualmente son una alternativa para la agricultura sostenible, han sido utilizadas en los cultivos de maíz, frijol, arveja, trébol, tomates, entre otros. 

La comprensión de las comunidades microbianas de la rizosfera puede ayudar a comprender el funcionamiento del ecosistema, aunado a que nos puede permitir aplicar el conocimiento en otras áreas que benefician al ser humano.

description: A method for determining Zn content in zincian malachite from a relative location of reflections in an x-ray diffraction (XRD) pattern is reported. Based on the standard samples prepared by a micro-reactor, the (220) reflection of zincian malachite is selected as the reference peak to calculate the relative location of other reflections within the 2θ-range from 10° to 35°. After establishing the relationship between the Zn content and the relative location, the shifts of these reflections are considered comprehensively to determine the Zn content by multi-peak fitting. The new method takes full advantage of the XRD pattern, avoiding the interference of adjacent reflections in single-peak fitting, eliminating the systematic deviation among different instruments that causes the overall shift of the pattern. Comparing with the Rietveld refinement, the method is more convenient for ordinary user.

Neutrino oscillation physics has truly come of age in the last few years. It is now data driven (analogous to cosmology and much of high energy physics in general). Experimental techniques and the theoretical interpretation have developed dramatically. An example of the latter includes the more realistic analysis of neutrino oscillations in the framework of 3 or more mass eigenstates. The phenomenological emphasis has shifted from degenerate to hierarchical neutrino spectra.

description: Understanding the heterogeneous reactions and transformations between organic particles and gas–phase oxidants, such as ozone, within atmospheric aqueous phases is of crucial importance. However, investigating the aerosol/droplet phase presents significant challenges in distinguishing between interfacial and bulk scenarios in laboratory studies. In the present study, the physiochemical properties and heterogeneous ozone oxidation of multiphase reactions in a water droplet containing maleic acid (MA) are investigated by means of both classical and quantum methods. The relative occurrence of interfacial and bulk reactions is dependent on the bulk affinity of O3 and the interfacial affinity of reacting MA, which is predominantly found in the bulk phase. Reaction energetics and rate coefficients have been evaluated in different environments (gas phase, at the particle interface, and in the bulk) using a multilevel approach. The presence of interfacial water molecules enhances the initial reaction step of MA + O3, with a larger rate coefficient at the air–water interface than in the gas phase. By assuming a Langmuir–Hinshelwood behavior and comparing it with the bulk, the ozonolysis of maleic acid mainly occurs in the bulk with rate coefficients of the order of 10−19 and 10−16 cm3.molecule−1. s−1, respectively. The calculated rate coefficients are compared with reported values. The original method presented here quantifies the influence of a specific heterogeneous environment on the reaction rates taking into account explicit solvation.

description: We study the present evolutionary status of the binary system containing the 2.66 ms pulsar PSR J1417-4402 in a 5.4 day orbit. This is the pulsar in the original source 3FGL J1417.5-4402, that has undergone a transition from X-ray state to a pulsar state, just like some redbacks did. The system has many characteristics similar to redback pulsars family, but is on a much wider orbit. We show that close binary evolution including irradiation feedback driven by the luminosity due to accretion onto the neutron star component of the pair, and evaporation due to pulsar emission, is able to account for the masses of the components and the photometric data of the donor star. The tracks leading to the present PSR J1417-4402 are degenerate within a range of parameters, suggesting that the {\it same} physics invoked to explain the redback/black widows groups leads to the formation of much wider orbit systems, outside the redback region limits.

description: Granular materials size segregate when exposed to external periodic perturbations such as vibrations. Moreover, mixtures of grains of different sizes spontaneously segregate in the absence of external perturbations: when a mixture is simply poured onto a pile, the large grains are more likely to be found near the base, while the small grains are more likely to be near the top. Here, we report a spontaneous phenomenon arising when we pour a mixture between two vertical plates: the mixture spontaneously stratifies into alternating layers of small and large grains whenever the large grains are rougher than the small grains. In contrast, we find only spontaneous segregation when the large grains are more rounded than the small grains. The stratification is related to the occurrence of avalanches; during each avalanche the grains comprising the avalanche spontaneously stratify into a pair of layers through a "kink" mechanism, with the small grains forming a sublayer underneath the layer of large grains.

Começando com práticas antigas em diversas culturas para aprimorar a aparência física, o texto explora como a especialidade se desenvolveu nos séculos XIX e XX. A era de 1950 a 1990 testemunhou o surgimento de procedimentos não cirúrgicos, incluindo peelings químicos e preenchimentos dérmicos, juntamente com a descoberta da toxina botulínica para tratar rugas. No século XXI, a tecnologia a laser e dispositivos de radiofrequência e ultrassom revolucionaram a dermatologia estética, proporcionando opções menos invasivas. A coleta de dados foi realizada no mês de setembro de 2023 nos bancos de dados BIREME e PubMed.  O futuro promissor da área reside em avanços como terapias com células-tronco e engenharia de tecidos, além da crescente conscientização sobre saúde da pele e a demanda por procedimentos personalizados e seguros. O artigo destaca a importância contínua da pesquisa e inovação, prevendo uma transformação significativa na prática e nos resultados da dermatologia estética.

description: A possible discovery of a relatively light charged Higgs boson H^+ in near future experiments, with a mass M_{H+} ~< 110 GeV, together with the present LEP2 direct limits on the chargino and neutral Higgs sectors, would disfavour the minimal supersymmetric standard model as well as its frequently discussed next-to-minimal supersymmetric extension. We show that a supersymmetric origin can naturally be ascribed to the existence of such a light charged Higgs scalar within the context of the recently introduced minimal nonminimal supersymmetric standard model.

Order α_s^2 Contributions to charm production in charged-current deep-inelastic lepton-hadron scattering

description: The most important part of the order $α_s^2$ corrections to the charm component of the charged-current structure functions $F_2(x,Q^2)$ and $F_3(x,Q^2)$ have been calculated. This calculation is based on the asymptotic form of the heavy-quark coefficient functions corresponding to the higher order corrections to the W-boson-gluon fusion process. These coefficient functions which are in principle only valid for $Q^2 \gg m^2$ can be also used to estimate the order $α_s^2$ contributions at lower $Q^2$ values provided $x < 0.1$. It turns out that the above corrections are appreciable in the large $Q^2$-region and they explain the discrepancy found for the structure functions between the fixed-flavour scheme (FFS) and the variable-flavour-number scheme (VFNS). These corrections also hamper the extraction of the strange-quark density from the data obtained for the charged-current and the electromagnetic-current processes.

description: This paper presents an investigation of the discharge propagation (DP) to the readout electrode that occurs with a microsecond time delay after a primary discharge that develops inside a GEM foil hole. A single hole THGEM (THick GEM) foil that enables a controlled discharge position and the induction of primary discharge with an over-voltage in the THGEM foil has been used in the initial DP measurements. In order to justify the use of a custom-made THGEM foil, additional measurements were made with a standard GEM foil. Correlated optical (with an ordinary SLR and a high-speed camera) and electrical measurements of the delayed DP were made for Ne-CO$_2$-N$_2$ (90-10-5) mixture and with different powering configurations. Measurements show that the delayed DP happens without a drift field, with an inverted induction field, inverted THGEM voltages or an inverted drift field. After the primary discharge, there is a charge transfer in the induction region at an induction field value below that of the onset field for DP. In the time between the primary discharge and the delayed DP, three different current regimes are observed, which suggests multiple charge transfer mechanisms in the induction region. High-speed camera recordings provide valuable insight into the time evolution of the primary and the delayed DP, especially when correlated with electrical measurements.

description: Aerosol physicochemical mixing state, defined as the chemical, phase, and internal structure of a population of aerosols, is complex and under-characterized regarding its role in the atmosphere. The compositional and microphysical properties of the aerosol particle strongly impact its atmospheric processes, including water uptake and ice nucleation (IN) activities. However, the relationship between IN activity and particle microphysics remains underdeveloped, as the aerosol particle IN activity, composition, morphology, and size are highly intercorrelated. In this article, we demonstrate the efficacy of a microfluidic static well trap device for testing both IN activity and effloresced residual particle morphology in the same droplet. We link cationic composition with both IN activity and residual particle morphology in droplets containing sodium chloride, calcium chloride, and the biological ice nucleating particle (INP) Snomax. Finally, we show a decoupling between IN activity and residual particle morphology within the same droplet for the chemical systems studied here.

description: The plastic deformation processes that occur in a tensily deformed High Density Polyethylene specimen were studied from full-field strain and strain rate measurements obtained by 3D DIC (Digital Image Correlation).The tensile tests were performed every 10{\textdegree}C from room temperature to 120{\textdegree}C . For temperatures below 60{\textdegree}C , it is shown that the strain localization effect becomes less pronounced when the temperature increases. For temperatures higher than 60{\textdegree}C , the material is found to exhibit double yielding behavior. By analyzing the DIC data in Lagrangian representation, it was possible to quantitatively highlight the strain localization effect that is specifically associated with the second yield. The second yield strain (E_{Y_2}) was measured and appeared to be independent of temperature. For temperatures smaller than 60{\textdegree}C , it was found that the threshold strain corresponding to (E_{Y_2}) also marks the onset of the deformation process phase during which the volume strain strongly increases. Based on previous studies of our research team and on literature we concluded that the critical strain (E_{Y_2}) corresponds to the onset of the lamellar morphology destruction. At high strain levels, the neck stabilization phase was shown to proceed according to a strain driven scheme characterized by threshold strains that are temperature independent. The experimental values of the threshold strain marking the onset of the stabilization phase are found to be in good agreement with those found using the Haward-Thackray model.

description: Die Kommunen in NRW verzeichnen seit mehreren Jahren eine verstärkte Zuwanderung, ob nun von EU-Bürgerinnen und Bürgern oder von Geflüchteten. Dabei ist die Zuwanderung nicht über alle Stadtteile einer Stadt gleichverteilt, sondern es bilden sich in allen kreisfreien Städten und Kreisen kleinräumige Zuwanderungsschwerpunkte heraus. Solche diversitätsgeprägten Orte sind in NRW häufig auch die ärmsten Stadtteile einer Stadt und damit Zielgebiete von Quartiersentwicklungsprogrammen. Das bedeutet, dass die Armenhäuser unserer Städte zugleich ihre Integrationsmotoren sein sollen. Dafür braucht es allerdings ein hohes Maß an integrationspolitischen Anstrengungen, in Form passgenauer Angebotslandschaften, integrierter Quartiersentwicklung und einer vorausschauenden Stadtentwicklungspolitik. Um einen Beitrag zur notwendigen Konzeption diversitätssensibler Quartiersentwicklung in Form der Förderung nachbarschaftlicher Beziehungen zu leisten, wird das Thema Nachbarschaft in diversitätsgeprägten und armutsbelasteten Stadtteilen in vier Teilstudien untersucht. Dabei stehen die jeweiligen lokalen Variationen, wie Diskriminierungserfahrungen, digitale Nachbarschaftskontakte bauliche Probleme und lokale Konflikte um armutsgeprägte Zuwanderung im Fokus. Die Ergebnisse zeigen, dass Nachbarschaft eine Ressource für alltägliche Integrationserfahrung darstellt, welche durch kommunale Integrationspolitik adressiert werden kann. Vor allem die Förderung lokaler Angebotslandschaften und Digitalisierung ist dafür eine geeignete Strategie. Für die kommunalen Integrationszentren NRW bedeutet dies, dass sie raumbezogene Steuerungsinstrumente entwickeln sollten, welche sowohl die sozialstrukturellen Dynamiken als auch die lokalen Angebotsstrukturen im Blick behalten. Weiterhin bedarf es der dauerhaften Thematisierung von Rassismus und Diskriminierungserfahrung, wie die Ergebnisse nahelegen. Zudem ist es sinnvoll, auch raumbezogene Kooperationen zu entwickeln, um sozialräumlichen Herausforderungen zu begegnen sowie digitale Praktiken unter den Nachbarinnen und Nachbarn eines Stadtteils in den Blick zu nehmen. Die Kommunalen Integrationszentren NRW sind als mittlerweile etablierte und gut vernetzte kommunale Organisationseinheiten in der Lage, diese Steuerungsinstrumente zu entwickeln und zu implementieren.

Marshall-Peierls sign rule in frustrated Heisenberg chains

description: We consider the frustrated antiferromagnetic s=1 Heisenberg quantum spin chain with regard to the Marshall-Peierls sign rule (MPSR). By using exact diagonalization data we investigate the breakdown of the MPSR in dependence on frustration and compare our findings with data for s=1/2. We calculate a critical value of frustration J_2(crit) where the MPSR is violated. The extrapolation of this value to the infinite chain limit holds J_2(crit) approx. 0.016, lower than in the case of s=1/2 (J_2(crit) approx. 0.027). This points to a stronger influence of frustration in the case of s=1. Nevertheless the calculation of the weight of the Ising-states violating the MPSR shows that the MPSR holds approximately even for quite large frustration and may be used for numerical techniques.

description: Light-absorbing organic aerosol (brown carbon, BrC) can have a significant impact on the radiative balance of the Earth’s atmosphere. However there are still substantial uncertainties regarding the formation, composition, and radiative properties of BrC. In this study, we conducted laboratory experiments to investigate the pH dependence of BrC formation in both aerosol particles and bulk phase solutions. Using glyoxal, ammonia, and ammonium salts, we generated precursor solutions under varying bulk pH conditions ranging from 0.69 to 8.43. Drying the solutions either in the bulk or aerosol phase resulted in BrC formation. The resulting organic material was analyzed to determine its chemical composition and optical properties. Under the set of conditions investigated here, neutral to basic conditions of relevance to cloud water favored BrC formation for both aerosols and bulk solutions. In contrast, BrC products were formed under acidic conditions only in the aerosol phase. Due to rapid equilibration with the gas phase and evaporative losses of water, the aerosols probed here likely had extremely low pH values, well below the bulk pH of 0.69. By achieving such acidic conditions in the aerosol phase, new acid-catalyzed pathways are possible to form BrC. These findings indicate brown carbon formation is favored at both high and very low pH, and further point to the importance of using aerosol samples in studies of pH dependent chemistry of relevance to the atmosphere.

Further Evidence for Threefold Maximal Lepton Mixing and a Hierarchical Spectrum of Neutrino Mass-Squared Differences

description: The phenomenological case for threefold maximal lepton mixing is strengthened by more detailed comparison with existing data. The atmospheric neutrino data are self-consistent and in good agreement with the threefold maximal mixing prediction R = 2/3 (chi-squared/dof = 4.3/5, CL = 51%). Including partially con- tained event data, the zenith angle dependence also points to threefold maximal mixing, ruling-out a range of mixing schemes, including that of Fritzsch and Xing. Accounting for `de facto' uncertainties in solar neutrino fluxes, the solar neutrino data (including HOMESTAKE) are shown to be consistent with threefold maximal mixing (chi-squared/dof = 5.1/3, CL = 16%), as is the upper limit from the LSND appearance experiment. Detailed pred- ictions for forthcoming long-base-line reactor and accelerator experiments are presented.

description: We present a theoretical discussion of the reversible parking problem, which appears to be one of the simplest systems exhibiting glassy behavior. The existence of slow relaxation, nontrivial fluctuations, and an annealing effect can all be understood by recognizing that two different time scales are present in the problem. One of these scales corresponds to the fast filling of existing voids, the other is associated with collective processes that overcome partial ergodicity breaking. The results of the theory are in a good agreement with simulation data; they provide a simple qualitative picture for understanding recent granular compaction experiments and other glassy systems.

description: This anthropological research gives insight in the meaning of music for the religious experience of participants of the processions in Antigua, Guatemala. By placing the theories of lived religion, material religion and aesthetics at the central stage, the process whereby the marchas fúnebres, the music played in the processions, mediate religious experience for the participants is explained. The material-sensorial elements of the processions, the practice of carrying, and the emotional effect of the music which refers to extra-musical memories, all provide the context for and strengthen the communication of the participants with God.

description: This article presents the first experimental analysis of the influence of single, micrometer-sized aerosol particles on the reflectivity of a resonant Fabry-Pérot etalon (FPE). The results are presented along with a theoretical model capable of describing and predicting the particle influence on the transfer function of the etalon. The presence of the particle in the cavity alters the etalon reflectivity in the operating point up to several percent. Based on our findings, we show that the etalon reflectivity is mainly affected by light extinction by the particle. Phase effects due to interference of forward scattered light could not be observed experimentally in the investigated size range. However, extrapolations on the presented theoretical model show a significant dependence of the phase contribution on the collection angle of the etalon. Comparable magnitudes of the phase and extinction contribution are reached if the etalon geometry is slightly altered. This could be exploited to obtain the phase shift of the coherently forward scattered light. Cavity geometries can also be adapted to reduce the direct particle effect if it is undesired. In addition, the change in the transfer function of the etalon is analyzed and discussed, as it is especially relevant for measurement techniques such as photothermal interferometry.
