description: Recognition of the importance of authentic leadership is growing in popularity amonlead?ership scholars. However, little remains known about how it is valued or received among practicing school leaders. The purpose of this research was to explore the perspectives and experiences of school leaders with reference to authentic leadership in Irish primary school leaders. As this is a scoping study, a qualitative research design was adopted, using semi-structured interviews with school leaders. Core traits of self-awareness, balanced processing, relational transparency and internalized perspectives, that are associated with authentic leadership emerged as important for those inter-viewed. Barriers and facilitators of authentic leadership were also identified including educational policy, procedures and school culture.

description: The eclipses of certain types of binary millisecond pulsars (i.e. `black widows' and `redbacks') are often studied using high-time-resolution, `beamformed' radio observations. However, they may also be detected in images generated from interferometric data. As part of a larger imaging project to characterize the variable and transient sky at radio frequencies <200 MHz, we have blindly detected the redback system PSR J2215+5135 as a variable source of interest with the Low-Frequency Array (LOFAR). Using observations with cadences of 2 weeks - 6 months, we find preliminary evidence that the eclipse duration is frequency dependent ($\propto ν^{-0.4}$), such that the pulsar is eclipsed for longer at lower frequencies, in broad agreement with beamformed studies of other similar sources. Furthermore, the detection of the eclipses in imaging data suggests an eclipsing medium that absorbs the pulsed emission, rather than scattering it. Our study is also a demonstration of the prospects of finding pulsars in wide-field imaging surveys with the current generation of low-frequency radio telescopes.

description: The Social Surveys Work Package (WP06) of the WorldFAIR project is focussed on the improvement of FAIR practices in the management of harmonised content in cross-national social surveys. The first report from the Work Package (Deliverable 6.1) provided an overview of the practices of comparative (cross-national) social surveys, through case studies of: (1) the European Social Survey (ESS) and (2) a satellite study, the Australian Social Survey International – European Social Survey (AUSSI-ESS). The focus of this Deliverable 6.2 is oriented towards progress on three recommendations (Rs) from that first report - the use of the DDI Lifecycle and variable cascade (R6.1 and R6.2), and requirements for formal registries of variables and reusable content (R6.5). To achieve this, this paper explores the development of recommended practices for the management and processing of cross-national survey data for the establishment of harmonised social science datasets. In this deliverable, we outline a proposed workflow for the processing of data harmonisation of social surveys, that takes account of the practical steps required to bring diverse content together in a machine-actionable way, and that could best take advantage of external registered, persistent content. This workflow considers the core steps involved in the harmonisation process, key issues that occur in the processing of data during this process, and potential resolutions of these issues. These resolutions are all oriented towards improving FAIR practices in the harmonisation process - through the use of reusable, accessible metadata structures that can both improve processing consistency for current projects, and be applied to future harmonisation projects. The key conclusions are two-fold. Firstly, there is a key need for the application of standardised workflows to enable consistent interaction with registry content held across multiple data repositories. The proposed workflow detailed in this report is a first effort at such a workflow model. Secondly, there is a need for consistent pre-processing of data and metadata within repositories to reduce error handling in the harmonisation process. The final section of the report provides an initial set of processing rules that could be used in such circumstances. The final third phase of this Work Package will then focus on testing this workflow and rules on new waves of data coming from the AUSSI and ESS projects.

The impact of the Russia – Ukraine war on scientific open access publishing and early career researchers
Creators: name: Halevi, Gali
Publisher: name: Zenodo
Year: 2023

description: Times of conflict put the entire scientific endeavour at risk, especially when a country needs to divert funding and persons to areas of military action and broader security. The impact of conflict on science can be seen in a lower number of publications and overall participation in science. The continuing conflict between Russia and Ukraine has a negative effect on their publications rates and within that, Open Access. In addition, an analysis of Ukraine's early career researchers landscape shows how this specific group of scientists was and still is impacted by the continuing war. In this presentation, we will look at the rates of Open Access publishing in both countries and the impact of the war on early career researchers through the bibliometric lens.

description: Thermal recovery of irradiated uranium dioxide lattice have been investigated by experimental groups and defects related to each recovery stages are estimated based on the indirect observations like activation energies. In this study, thermal recovery mechanisms of both neutron and alpha-particle irradiated uranium dioxide lattice is investigated by atomistic simulation methods. Isochronal and isothermal annealing have been applied to the irradiated samples. Following the same procedures of the experimental groups, activation energies are calculated with molecular dynamics simulations and compared with empirical data which show a good agreement. Migration energy barrier and the recovery energies of the obstruction type defects are calculated with molecular dynamics simulation and density functional theory. Recovery stages of the irradiated crystals are discussed however unlike the predictions of the most experimental groups, it is shown that neutron and alpha-particle irradiated crystal structures do not thermally recover for the same reason. All three recovery stages of neutron irradiated uranium dioxide crystal is attributed to oxygen interstitials while the three recovery stages of the alpha-particle irradiated crystals is considered to the oxygen - uranium, uranium and uranium interstitial defects respectively. Finally, the reason and the main driving force of thermal recovery of irradiated crystals is the obstruction type defects which give a lead to all other types of defects recover with themselves in each lattice recovery stages.

description: Let $A=[a_{n,k}]_{n,k\ge 0}$ be an infinite lower triangular matrix defined by the recurrence $$a_{0,0}=1,\quad a_{n+1,k}=r_{k}a_{n,k-1}+s_{k}a_{n,k}+t_{k+1}a_{n,k+1},$$ where $a_{n,k}=0$ unless $n\ge k\ge 0$ and $r_k,s_k,t_k$ are all nonnegative. Many well-known combinatorial triangles are such matrices, including the Pascal triangle, the Stirling triangle (of the second kind), the Bell triangle, the Catalan triangles of Aigner and Shapiro. We present some sufficient conditions such that the recursive matrix $A$ is totally positive. As applications we give the total positivity of the above mentioned combinatorial triangles in a unified approach.

description: If $G$ is a compact Lie group endowed with a left invariant metric $g$, then $G$ acts via pullback by isometries on each eigenspace of the associated Laplace operator $Δ_g$. We establish algebraic criteria for the existence of left invariant metrics $g$ on $G$ such that each eigenspace of $Δ_g$, regarded as the real vector space of the corresponding real eigenfunctions, is irreducible under the action of $G$. We prove that generic left invariant metrics on the Lie groups $G=\operatorname{SU}(2)\times\ldots\times\operatorname{SU}(2)\times T$, where $T$ is a (possibly trivial) torus, have the property just described. The same holds for quotients of such groups $G$ by discrete central subgroups. In particular, it also holds for $\operatorname{SO}(3)$, $\operatorname{U}(2)$, $\operatorname{SO}(4)$.

description: The South Pole Telescope has discovered one hundred gravitationally lensed, high-redshift, dusty, star-forming galaxies (DSFGs). We present 0.5" resolution 870um Atacama Large Millimeter/submillimeter Array imaging of a sample of 47 DSFGs spanning z=1.9-5.7, and construct gravitational lens models of these sources. Our visibility-based lens modeling incorporates several sources of residual interferometric calibration uncertainty, allowing us to properly account for noise in the observations. At least 70% of the sources are strongly lensed by foreground galaxies (mu_870um > 2), with a median magnification mu_870um = 6.3, extending to mu_870um > 30. We compare the intrinsic size distribution of the strongly lensed sources to a similar number of unlensed DSFGs and find no significant differences in spite of a bias between the magnification and intrinsic source size. This may indicate that the true size distribution of DSFGs is relatively narrow. We use the source sizes to constrain the wavelength at which the dust optical depth is unity and find this wavelength to be correlated with the dust temperature. This correlation leads to discrepancies in dust mass estimates of a factor of 2 compared to estimates using a single value for this wavelength. We investigate the relationship between the [CII] line and the far-infrared luminosity and find that the same correlation between the [CII]L_FIR ratio and Sigma_FIR found for low-redshift star-forming galaxies applies to high-redshift galaxies and extends at least two orders of magnitude higher in Sigma_FIR. This lends further credence to the claim that the compactness of the IR-emitting region is the controlling parameter in establishing the "[CII] deficit."

description: The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter. The strong time periodic potential of intense laser light can be used to generate hybrid photon-electron states. Interaction of light with Bloch states leads to Floquet-Bloch states which are essential in realizing new photo-induced quantum phases. Similarly, dressing of free electron states near the surface of a solid generates Volkov states which are used to study non-linear optics in atoms and semiconductors. The interaction of these two dynamic states with each other remains an open experimental problem. Here we use Time and Angle Resolved Photoemission Spectroscopy (Tr-ARPES) to selectively study the transition between these two states on the surface of the topological insulator Bi2Se3. We find that the coupling between the two strongly depends on the electron momentum, providing a route to enhance or inhibit it. Moreover, by controlling the light polarization we can negate Volkov states in order to generate pure Floquet-Bloch states. This work establishes a systematic path for the coherent manipulation of solids via light-matter interaction.

title: Ausgewählte Übergangsmetallboride und -silicide für die Sauerstoffentwicklungsreaktion
Creators: name: Habrich, Katja Maria
Publisher: name: UNSPECIFIED

description: Im Rahmen dieser Arbeit wurden Eisen- beziehungsweise Nickelboride sowie -silicide als Katalysatoren für die Sauerstoffentwicklungsreaktion untersucht. Zu den untersuchten Verbindungen gehören die phasenreinen Boride FeB, Fe₂B, Ni₂B und Ni₃B als auch die Silicide Ni₂Si, Ni₃₁Si₁₂, FeSi, Fe₅Si₃ und Fe₃Si. Darüber hinaus ließen sich Mischkristallreihen für einige Systeme herstellen. So konnten die festen Lösungen (Ni₁₋ₓFeₓ)₂B und (Co₁₋ₓFeₓ)₂B im Bereich 0 ≥x≥ 1, sowie (Ni₁₋ₓFeₓ)₃₁Si₁₂ und (Fe₁₋ₓMₓ)₃Si (M=Co, Mn, Ni) im Bereich 0 ≥x≥ 0,5 hergestellt werden. Im direkten Vergleich der Silicide mit den Boriden zeigte sich, dass die Mehrzahl der Silicide eine deutlich höhere Überspannung aufwies und damit katalytisch weniger aktiv war als die Boride. Dennoch zeigten einzelne Silicide ebenfalls sehr vielversprechende Ergebnisse. Es konnte erstmals an Siliciden gezeigt werden, dass die Überspannung durch Substitution des Metalls gesenkt werden und die OER-Aktivität somit gesteigert werden konnte. Sowohl bei den Siliciden als auch Boriden fallen vor allem nickelhaltige Proben durch eine hohe katalytische Aktivität auf. Neben pulverförmigen Proben wurden zusätzlich (Ni₁₋ₓFeₓ)₂B-Presslinge (0 ≥x≥ 0,5; x = 1) vermessen und mittels XPS vor nach der elektrochemischen Untersuchung charakterisiert. Zusammenfassend konnte in dieser Arbeit bestätigt werden, dass sowohl ausgewählte Silicide wie auch Boride vielversprechende Kandidaten für den Einsatz als OER-Katalysatoren darstellen und insbesondere mittels Substitution durch Übergangsmetalle deutlich optimiert werden können.

description: We discuss how the redshift (Mattig) method in Friedmann cosmology relates to dynamical distance indicators based on Newton's gravity (Teerikorpi 2011). It belongs to the class of indicators where the relevant length inside the system is the distance itself (in this case the proper metric distance). As the Friedmann model has Newtonian analogy, its use to infer distances has instructive similarities to classical dynamical distance indicators. In view of the theoretical exact linear distance-velocity law, we emphasize that it is conceptually correct to derive the cosmological distance via the route: redshift (primarily observed) --> space expansion velocity (not directly observed) --> metric distance (physical length in "cm"). Important properties of the proper metric distance are summarized.

This publishing industry generally provides an internet based digital platform for the publication of research output with unrestricted access to the public. The growth of open access publishing and scholarly communication has been very remarkable in the global North. However, this has created a huge financial burden in many developing countries in sharing their findings as the author needs to pay thousands of dollars. This, session will not be discussed in detail this obvious inequity, because there is much more hidden challenge that the globally north general does experience. the knowledge might free available to access digitally, however can everyone access equally? Is the cost of access/connection the digital platform equitable in all geographical locations?

description: Over the past decade, observations of giant exoplanets (Jupiter-size) have provided key insights into their atmospheres, but the properties of lower-mass exoplanets (sub-Neptune) remain largely unconstrained because of the challenges of observing small planets. Numerous efforts to observe the spectra of super-Earths (exoplanets with masses of one to ten times that of Earth) have so far revealed only featureless spectra. Here we report a longitudinal thermal brightness map of the nearby transiting super-Earth 55 Cancri e revealing highly asymmetric dayside thermal emission and a strong day-night temperature contrast. Dedicated space-based monitoring of the planet in the infrared revealed a modulation of the thermal flux as 55 Cancri e revolves around its star in a tidally locked configuration. These observations reveal a hot spot that is located 41 +- 12 degrees east of the substellar point (the point at which incident light from the star is perpendicular to the surface of the planet). From the orbital phase curve, we also constrain the nightside brightness temperature of the planet to 1380 +- 400 kelvin and the temperature of the warmest hemisphere (centred on the hot spot) to be about 1300 kelvin hotter (2700 +- 270 kelvin) at a wavelength of 4.5 microns, which indicates inefficient heat redistribution from the dayside to the nightside. Our observations are consistent with either an optically thick atmosphere with heat recirculation confined to the planetary dayside, or a planet devoid of atmosphere with low-viscosity magma flows at the surface.

description: Climate change has led to changes in the strength of directional selection on seasonal timing. Understanding the causes and consequences of these changes is crucial to predict the impact of climate change. But are observed patterns in one population generalizable to others, and can spatial variation in selection be explained by environmental variation among populations? We used long-term data (1955–2022) on blue and great tits co-occurring in four locations across the Netherlands to assess inter-population variation in temporal patterns of selection on laying date. To analyse selection, we combine reproduction and adult survival into a joined fitness measure. We found distinct spatial variation in temporal patterns of selection which overall acted towards earlier laying, and which was due to selection through reproduction rather than through survival. The underlying relationships between temperature, bird and caterpillar phenology were however the same across populations, and the spatial variation in selection patterns is thus caused by spatial variation in the temperatures and other habitat characteristics to which birds and caterpillars respond. This underlines that climate change is not necessarily equally affecting populations, but that we can understand this spatial variation, which enables us to predict climate change effects on selection for other populations.

description: The Indian real estate sector, the second-largest employment generator in the country after agriculture, has experienced significant challenges and changes in recent years, with the COVID-19 pandemic acting as a catalyst for transformation. Before the pandemic, the sector faced hurdles such as demonetization and regulatory reforms like RERA and GST, which slowed down project launches. However, there was a push from the government to boost the realty sector, including allowing mutual funds to invest in Real Estate Investment Trusts (REITs).When COVID-19 struck in 2020, it brought about a wave of disruptions. The nationwide lockdown halted ongoing projects, leading to construction delays and impacting the real estate market significantly. But amidst these challenges, the sector also witnessed innovation, with the adoption of video conferencing for property sales.As we look ahead, the real estate industry in India is poised for significant changes. Sustainability and technology adoption will be key drivers of success, and home ownership is likely to become a priority, especially among millennials. The market will continue to grapple with the demand-supply gap, particularly in mid and premium segments. However, initiatives like REITs and government economic boosters could provide the much-needed impetus.In this ever-evolving landscape, stakeholders in the Indian real estate market will need to adapt, strategize, and seize the opportunities presented by a post-pandemic world. It's a sector at the crossroads, with the potential for both challenges and growth in the coming years.

description: High finesse Fabry-Perot(FP) cavity is a very important frequency reference for laser stabiliza- tion, and is widely used for applications such as precision measurement, laser cooling of ions or molecules. But the non-linear response of the piezoelectric ceramic transducer (PZT) in the FP cav- ity limits the performance of the laser stabilization. Measuring and controlling such non-linearity are important. Here we report an in-situ, optical method to characterize this non-linearity by measuring the resonance signals of a dual-frequency laser. The differential measurement makes it insensitive to laser and cavity drifting, and has a very high sensitivity. It can be applied for various applications with PZT, especially in an optical lab.

Carrot & Stick: Policy as a driver for Open Science
Creators: name: Hermans, Katherine
Publisher: name: Zenodo
Year: 2023

description: In order to establish Open Science as the default at the UZH, the Open Science team developed a university wide, Open Science Policy. This document sets out expectations and recommendations on ways in which the practices and values of an open academic culture can be integrated into the structure of the UZH, and in its research and teaching. All UZH employees and students were able to comment on the draft policy in 2020 by means of a survey. Over 2000 UZH members took part in the survey, 642 filled out the entire questionnaire. At the same time, the Open Science Committee reviewed the policy, and several faculties and institutes provided institutional feedback. An overwhelming majority welcome an Open Science culture and support practices that promote open exchange, transparency, reproducibility and accountability. However, the fear that career opportunities for young researchers were at risk. This means it is important to communicate clearly that in view of the global movement towards Open Science, an open scientific practice can also improve career opportunities in the future. It also became clear that the requirements of the individual departments are very different and must therefore be taken into account during the implementation of the policy. A main point of criticism furthermore was the fact that Open Science requirements were formulated as mandatory in the first version of the policy, because such fundamental changes in the research culture need time and resources, this input is in line with the UNESCO Recommendation. Based on this feedback, the draft has been revised and now includes expectations and recommendations instead of requirements. This also addresses the concerns that many changes in the scientific process require time and resources.

description: We analyze the contribution of the quiver kinetic energy acquired by an electron in an oscillating electric field to the energy balance in atomic ionization processes by a short laser pulse. Due to the time dependence of this additional kinetic energy, a temporal average is assumed to maintain a stationary energy conservation rule. This rule is used to predict the position of the peaks observed in the photo electron spectra (PE). For a flat top pulse envelope, the mean value of the quiver energy over the whole pulse leads to the concept of ponderomotive energy $U_{p}$. However for a short pulse with a fast changing field intensity a stationarity approximation could not be precise. We check these concepts by studying first the photoelectron (PE) spectrum within the Semiclassical Model (SCM) for a multiple steps pulses. The SCM offers the possibility to establish a connection between emission times and the PE spectrum in the energy domain. We show that PE substructures stem from ionization at different times mapping the pulse envelope. We also present the analysis of the PE spectrum for a realistic sine-squared envelope within the Coulomb-Volkov and \textit{ab initio} calculations solving the time-dependent Schrödinger equation. We found that the electron emission amplitudes produced at different times interfere with each other and produce a new additional pattern, that overlap the above-threshold ionization (ATI) peaks.

Consequently, this establishes the veracity of statements that were long observed or expected to be true, but not proven, e.g., operators with B-L=0 are of even dimension, B-L must be an even number, etc. These results remain true even if the SM is augmented by any number of right-handed neutrinos with L=1.

title: Berechnung von Key Performance Indicators aus Positionsdaten im Bereich Fußball
Creators: name: Mikosch, Alexander
Year: 2019

description: Das Ziel der Masterarbeit ist eine Methodik zu entwickeln um Key Perfermonace Indikatoren berechnen zu können. Diese KPI’s verändern die Spielanalyse enorm, da Positionsdaten im Vergleich zu anderen Analysemethoden neu sind. In dieser Masterarbeit findet man zwei KPI’s:
1.) das Defensives Packing, welches die überspielten Gegner bei einem Pass zählt
2.) die Raumkontrolle, in der die Fläche ,die ein Team kontrolliert, berechnet wird.
Durch Methodiken aus dem Mathematikstudium habe ich die KPI’s in ihre Einzelteile
zerlegt und diese mit abstrakten Methoden beschrieben.
Damit man auch mit den sehr umfangreichen Positionsdaten umgehen kann, wurden zwei Programme erstellt, welche die Methodiken darauf anwenden.
Die Ergebnisse dieser Masterarbeit sind somit die erstellten Programme und die
entwickelten Methodiken zur Berechnung der KPI’s.
Diese Masterarbeit ist für alle Sportwissenschaftler sowie Mathematiker und allen anderen Interessenten aus dem Bereich Sportanalyse lohnenswert.
description: The goal of this master thesis is to develop a methodology to calculate key performance indicators. These KPI’s change the game analysis enormously, because position data are new compared to other analysis methods. In this master thesis you will find two KPI’s:
1) the Defensive Packing, which counts the overplayed opponents on a pass
2) the room control, in which the area that a team controls is calculated.
Using methods from my mathematics courses, I have broken down the KPI’s into their individual parts and described them using abstract methods.
In order to be able to deal with the very extensive position data, two programs were created
which apply the methodologies to those position data.
The results of this master thesis are thus the created programs and the developed methods
for calculating the KPI’s.
This Master’s thesis is intended for sports scientists, mathematicians and all other Interested individuals from the field of sports analysis.

description: Utilizing an archived Suzaku data acquired on 2007 December 25 for 46 ks, X-ray spectroscopic properties of the dipping and eclipsing low-mass X-ray binary EXO 0748$-$676 were studied. At an assumed distance of 7.1 kpc, the data gave a persistent unabsorbed luminosity of $3.4\times10^{36}$ erg cm$^{-2}$ s$^{-1}$ in 0.6 $-$ 55 keV. The source was in a relatively bright low/hard state, wherein the 0.6 $-$ 55 keV spectrum can be successfully explained by a "double-seed" Comptonization model, incorporating a common corona with an electron temperature of $\sim13$ keV. The seed photons are thought to be supplied from both the neutron star surface, and a cooler truncated disk. Compared to a sample of non-dipping low-mass X-ray binaries in the low/hard state, the spectrum is subject to stronger Comptonization, with a relatively larger Comptonizing $y$-parameter of $\sim1.4$ and a larger coronal optical depth of $\sim5$. This result, when attributed to the high inclination of EXO 0748$-$676, suggests that the Comptonizing corona may elongate along the disk plane, and give a longer path for the seed photons when viewed from edge-on inclinations.

description: Since its outburst in 1997 GS 135-64 stayed in quiescence. In June 2015 renewed activity of GS 1354-64 was observed. Based on our analysis of energy spectra and timing properties obtained from Swift/XRT monitoring data we found that GS 1354-64 stayed in the hard state during the entire outburst. Such a hard state only (or "failed" outburst) has also been observed in 1997. In addition, we analysed an XMM-Newton observation taken on August 6th. We compared variability on long and short time scales using covariance ratio and found that the ratio showed a decrease towards lower energies instead of the increase that has been found in other black hole X-ray binaries. There are now two sources (H 1743-322 and GS 1354-64) that do not show an increase towards lower energies in their covariance ratio. Both sources have been observed during "failed" outbursts and showed photon indices much harder than what is usually observed in black hole X-ray binaries.

description: A particular feature of an aperiodic design of cladding of Bragg reflection waveguides to demonstrate a dispersion blue-shift is elucidated. It is made on the basis of a comparative study of dispersion characteristics of both periodic and aperiodic configurations of Bragg mirrors in the waveguide system, wherein for the aperiodic configuration three procedures for layers alternating, namely Fibonacci, Thue-Morse and Kolakoski substitutional rules are considered. It was found out that, in a Bragg reflection waveguide with any considered aperiodic cladding, dispersion curves of guided modes appear to be shifted to shorter wavelengths compared to the periodic configuration regardless of the modes polarization.

description: We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg states. The strong polarizabilities of the Rydberg levels increases the interaction strength between atoms and ions by many orders of magnitude, as compared to the case of ground state atoms, and may be mediated over micrometers. We calculate that such interactions can be used to generate entanglement between an atom and the motion or internal state of an ion. Furthermore, the ion could be used as a bus for mediating spin-spin interactions between atomic spins in analogy to much employed techniques in ion trap quantum simulation. The proposed scheme comes with attractive features as it maps the benefits of the trapped ion quantum system onto the atomic one without obviously impeding its intrinsic scalability. No ground state cooling of the ion or atom is required and the setup allows for full dynamical control. Moreover, the scheme is to a large extent immune to the micromotion of the ion. Our findings are of interest for developing hybrid quantum information platforms and for implementing quantum simulations of solid state physics.

description: A concordance model for angular momentum evolution has been developed by multiple investigators. This approach postulates that star forming regions and clusters are an evolutionary sequence which can be modeled with assumptions about the coupling between protostars and accretion disks, angular momentum loss from magnetized winds that saturates in a mass-dependent fashion at high rotation rates, and core-envelope decoupling for solar analogs. We test this approach by combining established data with the large h Per dataset from the MONITOR project and new low-mass Pleiades data. We confirm prior results that young low-mass stars can be used to test star-disk coupling and angular momentum loss independent of the treatment of internal angular momentum transport. For slow rotators, we confirm the need for star-disk interactions to evolve the ONC to older systems, using h Per (age 13~Myr) as our natural post-disk case. Further interactions are not required to evolve slow rotators from h Per to older systems, implying no justification for extremely long-lived disks as an alternative to core-envelope decoupling. However, our wind models cannot evolve rapid rotators from h Per to older systems consistently; this appears to be a general problem for any wind model that becomes ineffective in low-mass young stars. We outline two possible solutions: either there is cosmic variance in the distribution of stellar rotation rates in different clusters or there are substantially enhanced torques in low-mass rapid rotators. We favor the former explanation and discuss observational tests that could be used to distinguish them. If the distribution of initial conditions depends on environment, models which test parameters by assuming a universal underlying distribution of initial conditions will need to be re-evaluated.

description: Parasitoids in the genus Lysiphlebus specialize on ant-tended aphids and have previously been reported to mimic the CHC profiles of their aphid hosts to avoid detection by ants. However, the precise mechanisms that mediate reduced ant aggression toward Lysiphlebus spp. are not known, nor is it clear whether such mechanisms are broadly effective or specialized on particular aphid hosts. Here we explore the effects of wasp genotype and host environment on Lysiphlebus cuticular hydrocarbon (CHC) profiles and ant aggression. Rearing asexual Lysiphlebus lines in different host aphid environments revealed effects of both wasp line and aphid host on wasp CHCs. However, variation in genotype and host affected different features of the CHC profile, with wasp genotype explaining most variation in linear and long-chain methyl alkanes, while aphid host environment primarily influenced short-chain methyl alkanes. Subsequent behavioural experiments revealed no effects of host environment on ant aggression, but strong evidence for genotypic effects. The influence of genotypic variation on experienced ant aggression and relevant chemical traits is particularly relevant in light of recent evidence for genetic divergence among Lysiphlebus parasitoids collected from different aphid hosts.
