description: We present a new approach to observationally constrain where the tails of Jellyfish (JF) galaxies in groups and clusters first appear and how long they remain visible with respect to the moment of their orbital pericenter. This is accomplished by measuring the distribution of their tail directions with respect to their host's center, and their distribution in a projected velocity-radius phase-diagram. We then model these observed distributions using a fast and flexible approach where JF tails are painted onto dark matter halos according to a simple parameterised prescription, and perform a Bayesian analysis to estimate the parameters. We demonstrate the effectiveness of our approach using observational mocks, and then apply it to a known observational sample of 106 JF galaxies with radio continuum tails located inside 68 hosts such as groups and clusters. We find that, typically, the radio continuum tails become visible on first infall when the galaxy reaches roughly three quarters of r$_{200}$, and the tails remain visible for a few hundred Myr after pericenter passage. Lower mass galaxies in more massive hosts tend to form visible tails further out and their tails disappear more quickly after pericenter. We argue that this indicates they are more sensitive to ram pressure stripping. With upcoming large area surveys of JF galaxies in progress, this is a promising new method to constrain the environmental conditions in which visible JF tails exist.

What leads to premature upper cut-off frequencies of auroral radio emission from hot magnetic stars?

description: Recently a large number of hot magnetic stars have been discovered to produce auroral radio emission by the process of electron cyclotron maser emission (ECME). Such stars have been given the name of Main-sequence Radio Pulse emitters (MRPs). The phenomenon characterizing MRPs is very similar to that exhibited by planets like the Jupiter. However, one important aspect in which the MRPs differ from aurorae exhibited by planets is the upper cut-off frequency of the ECME spectrum. While Jupiter's upper cut-off frequency was found to correspond to its maximum surface magnetic field strength, the same for MRPs are always found to be much smaller than the frequencies corresponding to their maximum surface magnetic field strength. In this paper, we report the wideband observations (0.4--4.0 GHz) of the MRPs HD 35298 that enabled us to locate the upper cut-off frequency of its ECME spectrum. This makes HD 35298 the sixth MRP with a known constraint on the upper cut-off frequency. With these information, for the first time we investigate into what could lead to the premature cut-off. We review the existing scenarios attempting to explain this effect, and arrive at the conclusion that none of them can satisfactorily explain all the observations. We speculate that more than one physical processes might be in play to produce the observed characteristics of ECME cut-off for hot magnetic stars. Further observations, both for discovering more hot magnetic stars producing ECME, and to precisely locate the upper cut-off, will be critical to solve this problem.

description: The initial Audit of Disability Research in Australia was published online in July 2014, and included scientific and grey literature, government and non-government research reports. The current Audit of Disability Research in Australia Update Report 2017, hereafter referred to Audit Update 2017 was commissioned by National Disability Services (NDS), from a funding grant offered under the National Disability Research and Development Agenda, in June 2017 and undertaken by the Centre for Disability Research and Policy (CDRP) at the University of Sydney. The Audit Update 2017, used the same methods as previously, with minor modifications to align with the Centre for Applied Disability Research (CADR) Clearing House protocol. The Audit Update 2017 addressed disability research from Australia in the scientific literature between mid-2013 and mid-2017, and research reports from the Australian Bureau of Statistics (ABS), the Australian Institute of Health and Welfare (AIHW), and the Productivity Commission (PC).
The major differences between the reports from 2014 to 2017 are:The major differences in the time period between the initial 2014 Audit and the current AuditUpdate 2017 are as follows:• The majority of studies are in the domain of Education rather than Health and Wellbeing asin the 2014 Audit• The three most written about domains are Education, Economic Participation, and SocialRelationships in contrast to Health and Wellbeing, Education, and Economic Participation inthe 2014 Audit• The research designs utilised in the Audit Update 2017 were markedly similar to those in the2014 Audit. The most frequently appearing were qualitative studies and observationalstudies with the least frequently occurring study protocol only, historical analysis andmedia/ creative arts/ cultural analysis. In the 2014 Audit, most frequently occurring studydesigns were observational studies and qualitative studies with the least frequentlyoccurring study protocol only, systematic review, historical analysis and randomisedcontrolled trials (RCTs)• There has been an increase in the number of studies employing designs with larger samplesmore likely to be representative and permitting comparison of the circumstances of peoplewith disability with those of their non-disabled peers, however taken together these designsonly accounted for just under 1/10th of all studies.

description: We review some recent results on Sorkin's spacetime formulation of the entanglement entropy (SSEE) for a free quantum scalar field both in the continuum and in manifold-like causal sets. The SSEE for a causal diamond in a 2d cylinder spacetime has been shown to have a Calabrese-Cardy form, while for de Sitter and Schwarzschild de Sitter horizons in dimensions $d>2$, it matches the mode-wise von-Neumann entropy. In these continuum examples the SSEE is regulated by imposing a UV cut-off. Manifold-like causal sets come with a natural covariant spacetime cut-off and thus provide an arena to study regulated QFT. However, the SSEE for different manifold like causal sets in $d=2$ and $d=4$ has been shown to exhibit a volume rather than an area law. The area law is recovered only when an additional UV cut-off is implemented in the scaling regime of the spectrum which mimics the continuum behaviour. We discuss the implications of these results and suggest that a volume-law may be a manifestation of the fundamental non-locality of causal sets and a sign of new UV physics.

description: This study is the first national survey on attitudes toward people with disability in Australia. Over 2,000 people from across Australia participated in the Community Attitudes Survey in 2018. The survey asked respondents about their individual or personally held attitudes, as well as society or community perceptions about people with disability.
It is the first population-level representative survey, which means that the findings can be applied to the general Australian population.
The survey was developed by people with disability who were employed as co-researchers on the project team; questions thus tap into attitudes that are salient in the lives of people with disability in Australia.
The survey examined personal feelings and behaviours toward people with disability, as well as perceptions of how people with disability are treated by others in the community.
These findings represent a key step in documenting current attitudes towards people with disability in Australia, providing information about where policy efforts might be targeted for greatest effect to track progress towards a more inclusive society.

Can superbubbles accelerate ultra-high energy protons?

description: We critically assess limits on the maximum energy of protons accelerated within superbubbles around massive stellar clusters, considering a number of different scenarios. In particular, we derive under which circumstances acceleration of protons above peta-electronvolt (PeV) energies can be expected. While the external forward shock of the superbubble may account for acceleration of particles up to 100 TeV, internal primary shocks such as supernova remnants expanding in the low density medium or the collective wind termination shock which forms around a young compact cluster provide more favourable channels to accelerate protons up to 1 PeV, and possibly beyond. Under reasonable conditions, clustered supernovae launching powerful shocks into the magnetised wind of a young and compact massive star cluster are found to be the most promising systems to accelerate protons above 10 PeV. On the other hand, stochastic re-acceleration in the strongly turbulent plasma is found to be much less effective than claimed in previous works, with a maximum proton energy of at most a few hundred TeV.

 Abstract : When Darwin arrived in the Saint Paul and Saint Pierre islands he saw that the origin of the rocks is not volcanic. Indeed this rocks are composed by mylonite and serpentinite. These two islands are localized on a complex fracture zone where we can see an exhumation of mantle. This study deals about determination and analyses of the magnetic susceptibility around these two islands with an inverse problem. The results are in agreement with the last geological research but the method is not completely optimal. Indeed the values of magnetic susceptibility vary a lot between two spherical prisms. So one amelioration is to improve the method of resolution and apply the method in a larger area.
Emergence of a new HI 21-cm absorption component at z~1.1726 towards the gamma-ray blazar PKS~2355-106

description: We report the emergence of a new HI 21-cm absorption at z_abs = 1.172635 in the damped Lyman-alpha absorber (DLA) towards the gamma-ray blazar PKS 2355-106 (z_em~1.639) using science verification observations (June 2020) from the MeerKAT Absorption Line Survey (MALS). Since 2006, this DLA is known to show a narrow HI 21-cm absorption at z_abs = 1.173019 coinciding with a distinct metal absorption line component. We do not detect significant HI 21-cm optical depth variations from this known HI component. A high resolution optical spectrum (August 2010) shows a distinct Mg I absorption at the redshift of the new HI 21-cm absorber. However, this component is not evident in the profiles of singly ionized species. We measure the metallicity ([Zn/H] = -(0.77\pm0.11) and [Si/H]= -(0.96\pm0.11)) and depletion ([Fe/Zn] = -(0.63\pm0.16)) for the full system. Using the apparent column density profiles of Si II, Fe II and Mg I we show that the depletion and the N(Mg I)/N(Si II) column density ratio systematically vary across the velocity range. The region with high depletion tends to have slightly larger N(Mg I)/N(Si II) ratio. The two HI 21-cm absorbers belong to this velocity range. The emergence of z_abs = 1.172635 can be understood if there is a large optical depth gradient over a length scale of ~0.35 pc. However, the gas producing the z_abs = 1.173019 component must be nearly uniform over the same scale. Systematic uncertainties introduced by the absorption line variability has to be accounted for in experiments measuring the variations of fundamental constants and cosmic acceleration even when the radio emission is apparently compact as in PKS 2355-106.

description: We report on the discovery of a new supergiant fast X-ray transient (SFXT), MAXI J0709$-$159, and its identification with LY CMa (also known as HD 54786). On 2022 January 25, a new flaring X-ray object named MAXI J0709$-$159, was detected by Monitor of All-sky X-ray Image (MAXI). Two flaring activities were observed in the two scans of $\sim 3$ hours apart, where the 2-10 keV flux reached $5\times 10^{-9}$ erg cm$^{-2}$ s$^{-1}$. During the period, the source exhibited a large spectral change suggesting that the absorption column density $N_\mathrm{H}$ increased from $10^{22}$ cm$^{-2}$ to $10^{23}$ cm$^{-2}$. NuSTAR follow-up observation on January 29 identified a new X-ray source with a flux of $6\times 10^{-13}$ erg cm$^{-2}$ s$^{-1}$ at the position consistent with LY CMa, which has been identified as B supergiant as well as Be star, located at the 3 kpc distance. The observed X-ray activity characterized by the short ($\lesssim$ several hours) duration, the rapid ($\lesssim$ a few seconds) variabilities accompanied with spectral changes, and the large luminosity swing ($10^{32}$-$10^{37}$ erg s$^{-1}$) agree with those of SFXT. On the other hand, optical spectroscopic observations of LY CMa revealed a broad $Hα$ emission line, which may indicate the existence of a Be circumstellar disk. These obtained results suggest that the optical companion, LY CMa, certainly has a complex circumstellar medium including dense clumps.

description: A compreensão do comportamento de compra dos consumidores relativamente a produtos de moda sustentável é essencial para a adaptação de qualquer empresa a esta tendência. De modo a estudar este mesmo comportamento de compra no contexto português, o presente artigo adapta o modelo de análise e o questionário desenvolvidos por Hui Zheng e Lei Chen no artigo Affecting factors of consumers' purchase decision on sustainable fashion clothing products (2020). Assim, são estudadas diferentes variáveis que explicam o comportamento de compra de produtos de moda sustentável neste contexto, concluindo-se que, entre as variáveis estudadas, as mais impactantes são a consciencialização do consumo sustentável por parte do consumidor e o ambiente de moda sustentável que rodeia o consumidor e a menos impactante é a variável que corresponde às características dos produtos de moda sustentável.

description: Mass loss remains a major uncertainty in stellar modelling. In low-mass stars, mass loss is most significant on the red giant branch (RGB), and will impact the star's evolutionary path and final stellar remnant. Directly measuring the mass difference of stars in various phases of evolution represents one of the best ways to quantify integrated mass loss. Globular clusters (GCs) are ideal objects for this. M4 is currently the only GC for which asteroseismic data exists for stars in multiple phases of evolution. Using K2 photometry, we report asteroseismic masses for 75 red giants in M4, the largest seismic sample in a GC to date. We find an integrated RGB mass loss of $Δ\bar{M} = 0.17 \pm 0.01 ~\mathrm{M}_{\odot}$, equivalent to a Reimers' mass-loss coefficient of $η_R = 0.39$. Our results for initial mass, horizontal branch mass, $η_R$, and integrated RGB mass loss show remarkable agreement with previous studies, but with higher precision using asteroseismology. We also report the first detections of solar-like oscillations in early asymptotic giant branch (EAGB) stars in GCs. We find an average mass of $\bar{M}_{\text{EAGB}}=0.54 \pm 0.01 ~\mathrm{M}_{\odot}$, significantly lower than predicted by models. This suggests larger-than-expected mass loss on the horizontal branch. Alternatively, it could indicate unknown systematics in seismic scaling relations for the EAGB. We discover a tentative mass bi-modality in the RGB sample, possibly due to the multiple populations. In our red horizontal branch sample, we find a mass distribution consistent with a single value. We emphasise the importance of seismic studies of GCs since they could potentially resolve major uncertainties in stellar theory.

description: A indústria têxtil tem sido considerada como uma das mais poluentes do mundo. Este facto, aliado a um consumo pouco consciente tem impactos dramáticos no meio ambiente, mas também na qualidade de vida dos trabalhadores das empresas deste setor. Este artigo pretende investigar o grau de consciencialização dos consumidores em relação à Fast-Fashion, examinando o conhecimento que têm sobre as suas implicações ambientais, éticas e sociais e analisando ainda o conhecimento e utilização de alternativas. Após uma breve revisão de literatura, foi realizado um estudo exploratório, através da aplicação de técnicas qualitativas (focus group) e quantitativas (online survey). Concluiu-se que, de forma geral, as pessoas que consomem mais Fast-Fashion são as mais jovens, sendo que os indivíduos entre os 15 e 24 anos são os que melhor compreendem os seus impactos sociais e ambientais. Além disso, foi possível perceber que os fatores que influenciam a compra de roupa através deste modelo de negócio são o preço e o fácil acesso. Em relação às alternativas existentes à Fast-Fashion, os consumidores com mais de 57 anos são os que conhecem melhor as alternativas.

We inject planets into 3D hydrodynamics simulations of IM Lupi, generating synthetic observations using Monte Carlo radiative transfer. We find that an embedded planet of 2-3 times the mass of Jupiter can reproduce non-Keplerian velocity perturbations, or `kinks', in the 12CO J=2-1 channel maps. Such a planet can also explain the spiral arms seen in 1.25mm dust continuum emission and 1.6 micron scattered light images. We show that the wake of the planet can be traced in the observed peak velocity map, which appears to closely follow the morphology expected from our simulations and from analytic models of planet-disc interaction.

description: O online dating consiste num sistema através do qual os utilizadores registados podem estabelecer ligações e comunicar entre si, através de dispositivos ligados à Internet com o objetivo de estabelecerem um relacionamento potencialmente amoroso e/ou sexual. Nos últimos dois anos, o isolamento e o distanciamento social, impostos pela pandemia COVID-19 impediram que as pessoas se pudessem relacionar livremente e sem restrições. Existem evidências na literatura de que esta situação poderá ter levado à intensificação da utilização das aplicações de relacionamentos. Neste contexto, este artigo pretende evidenciar a existência de alterações na utilização dessas aplicações, bem como a identificação dos fatores que mais influenciaram essas alterações. A metodologia utilizada neste estudo exploratório foi, numa primeira fase, um estudo qualitativo através de um focus group online e, numa fase posterior, foi aplicado um questionário a uma amostra de 134 indivíduos. Os resultados permitiram concluir que embora a população em geral se tenha distanciado cada vez mais devido à pandemia, as aplicações possibilitaram quebrar essa barreira.

description: The importance of tourism nowadays is crucial for the strengthening of the economy, not only for tourist cities but also for the cities that promote some type of event to boost the economy, that is, using events to generate income and a different dynamic for the communities. However, the Covid-19 pandemic caused numerous barriers to the events market around the world. Portugal was no exception, with all events being cancelled or postponed. This article aims to highlight the differences and challenges of preparing an event before and during the pandemic, with a special emphasis on the lessons for future events, whether in a pandemic environment or not. As an illustrative example, the case of Perlim, the largest Christmas Theme Park in Portugal is used, which had to adjust to government measures when the event was already underway, after being cancelled in 2020. This article describes the strategic and operational adaptations that were necessary and the changes that should remain for future cultural events like Perlim.

description: O mundo empresarial está em constante mudança e a pandemia COVID-19 acelerou, inevitavelmente, esse processo. Quer os consumidores, quer as empresas foram confrontados com novos métodos de comercialização mais dinâmicos e com outras oportunidades de negócio que eram pouco exploradas no passado. O significativo crescimento do e-commerce em tempos de pandemia e o aparecimento de pequenos negócios de roupa em segunda mão, são um perfeito exemplo desta ideia. Deste modo, o artigo tenta explorar de que forma é que a comercialização online pode vir a ser uma vantagem estratégica para pequenas empresas que estão a entrar, ou que têm essa ambição, no negócio de roupa em segunda mão. De forma a enriquecer o estudo, a MyCloma será o elo entre a teoria e a realidade: uma microempresa do domínio em análise, que começou a operar em 2020 e que já se destaca no mercado nacional, através do e-commerce, e em expansão para Espanha. Este estudo permite-nos compreender de que forma é que uma empresa do ramo da roupa em segunda mão poderá beneficiar com a inexistência de barreiras físicas, a maior oferta de produtos e a redução de custos face à comercialização tradicional. Além disso, são ainda apresentadas algumas considerações e recomendações práticas para o desenvolvimento e crescimento da empresa em questão, que poderão ser aplicadas a outras homólogas. De modo a obter um testemunho da MyCloma, o artigo conta uma entrevista realizada, em novembro de 2021, a uma das suas fundadoras.

Innovating regarding culture, leadership, and consumption in Peru

description: We recently went on a trip to Peru. Lima, the capital, and Cusco, the former capital of the Inca empire. We loved Peru and the Peruvian people albeit have mixed feelings about the country and those who live there. Do they really see the [Entrepreneurial] Spanish Conquistador Francisco Pizarro as their saviour and founder of the capital of Lima? Of course, not their saviour… but undeniably an entrepreneur who took considerable risks and followed a specific strategy to reach a specific objective: to take over an empire with all of its wealth. However, the tour guides we had (total of whom = 7) were very polite and politically correct about this historic character. “He is part of our history and I see him as a part of our past” one tour guide said. Yet another said he did what he did because he had to… So, forgiveness, again. To understand is to forgive, I once read. The extent of the power of the Catholic Church is immense... a legacy of the Spanish. What did Francisco Pizarro do? He conquered an empire with around 200 men. How did he do that? By gathering support from different sectors who were discontent with their leadership and empire. I am referring to the Inca empire, which was spread across an immense territory, was rich and had solved the problem of food (or the lack of it). There was food for everyone under their rule. A rule which had learned from numerous other cultures. Why were the Incas hated? Perhaps as they were very elitist and violent, when they needed to be, our tour guide in Cusco shared with us. They had a lot of deeply held enemies. Who united with the Spanish “conquistadors”. And yes, the rest is history. Albeit as one digs a little deeper, we see that perhaps the resentment is still there. One tour guide stated that on the commemoration of the 500 years of the colonization that, due to popular protests, the commemoration was seen as inappropriate, should not go ahead and that the monument of Francisco Pizarro should be taken down. It was. The wound still hurts as if it was opened yesterday. In some cases. This is our story, from the Inca trail right up to Machu Picchu and beyond. An autoethnographic account.

Comprehensive Listing of 156 Reliable Orbital Periods for Novae, Including 49 New Periods

description: I report on a large-scale search for the orbital periods (P) of most known nova systems, by looking for significant, coherent, and stable optical photometric modulation in two or more independent light curves taken mostly from the large surveys of TESS, Kepler, AAVSO, SMARTS, OGLE, ASAS, and ZTF. I have discovered 31 new orbital periods. Further, I have measured new periods for 18 novae with evolved companions, to 30 per cent accuracy, as based on their spectral energy distribution. Also, I have confirmed, improved, and rejected prior claims for P in 46 novae. (As part of this effort, I recognize that 5 novae display 1--3 coherent, significant, and transient periodicities 0.12--4.1 days, with these being mysterious as not being the orbital, spin, or superhump periods.) In all, I have compiled a comprehensive list of 156 reliable P values for novae. The histogram of nova periods shows a minimum P at 0.059 hours (85 minutes), and a Period Gap from 0.071--0.111 days (1.70--2.66 hours). The upper edge of the Period Gap is significantly different between novae (0.111 days), nova-like systems (0.131 days), and dwarf novae (0.141 days). A further issue from the histogram is that 31 per cent of nova systems have evolved companions, for which there has been no models or understanding for their current state or evolution. For the novae with red giant companions, 15-out-of-20 are in the bulge population, despite novae with main-sequence and subgiant companions having bulge fractions near 0.11--0.32.

description: We measure escape fractions, $f_{\rm esc}$, of ionizing radiation from galaxies in the SPHINX suite of cosmological radiation-hydrodynamical simulations of reionization, resolving halos with $M_{\rm vir} \gtrapprox 7.5 \times 10^7 \ M_{\odot}$ with a minimum cell width of $\approx 10$ pc. Our new and largest $20$ co-moving Mpc wide volume contains tens of thousands of star-forming galaxies with halo masses up to a few times $10^{11} \ M_{\odot}$. The simulated galaxies agree well with observational constraints of the UV luminosity function in the Epoch of Reionization. The escape fraction fluctuates strongly in individual galaxies over timescales of a few Myrs, due to its regulation by supernova and radiation feedback, and at any given time a tiny fraction of star-forming galaxies emits a large fraction of the ionizing radiation escaping into the inter-galactic medium. Statistically, $f_{\rm esc}$ peaks in intermediate-mass, intermediate-brightness, and low-metallicity galaxies ($M_{*} \approx 10^7 \ M_{\odot}$, $M_{1500} \approx -17$, $Z\lesssim 5 \times 10^{-3} \ Z_{\odot}$), dropping strongly for lower and higher masses, brighter and dimmer galaxies, and more metal-rich galaxies. The escape fraction correlates positively with both the short-term and long-term specific star formation rate. According to SPHINX, galaxies too dim to be yet observed, with $M_{1500} \gtrapprox -17$, provide about $55$ percent of the photons contributing to reionization. The global averaged $f_{\rm esc}$ naturally decreases with decreasing redshift, as predicted by UV background models and low-redshift observations. This evolution is driven by decreasing specific star formation rates over cosmic time.

What Best Paper Awards Have to Do with the Publication Practices?

description: Research awards provide recognition to outstanding researchers for excellent research (at least that is what they usually claim). But what does “excellent research” mean? Can we tell what the assessors and awarding bodies value from award descriptions? Do they value robust, transparent, and inclusive research? Do they incentivize adherence to core practices of Open Science? And who gets these awards? In this poster, I present the results of a collaborative project evaluating 222 Best Paper awards across disciplines. Notably, this work builds on an earlier project focused on two types of common awards for early career researchers in the fields of ecology and evolution. We found that journals and learned societies administering Best Paper awards publicly provide very little detail about their awards. Award descriptions almost never mention concepts that align with Open Science. Between 2001 and 2022, most individual winners were USA-affiliated, while researchers from the Global South and developing countries were uncommon. Sixty-one percent of individual winners were men. Overall, Best Paper awards miss the global calls for providing greater transparency and equitability in science. We can see them as an untapped opportunity for aligning incentives in the publication process and research recognition with values for greater openness and inclusivity. Including and highlighting Open Science practices in award criteria could raise awareness and act as a direct incentive for researchers to implement such practices in their research. For publishers, it is a chance to both signal and prove the trustworthiness of their publication assessment processes. For the broader public, it could showcase how community-driven action can drive the greater transparency and reliability of scholarly communication.
