The Impact of Socio-Cultural Values on Autistic Women: an Interpretative Phenomenological Analysis

description: The experiences of autistic females, particularly those of adult women are not well understood. The way that autism has been conceptualised traditionally has contributed to knowledge being largely extrapolated from experiences of autistic men and children. Lived experience research provides a valuable resource for understanding hard to reach voices, such as those of autistic women without intellectual disabilities. Existing research has examined the impact of “autism” on the person diagnosed with it, the impact of autistic people on others, and how culture may impact on how autism is understood. However, we have rarely questioned how culture has impacted on autistic people. This becomes more pertinent as the aetiology for sex differences in autism remain unclear, and we start to consider the role of gendered socialisation on how autistic women may present. This study aimed to examine how autistic women have made sense of their lived experiences in the context of the culture they are embedded within. This was achieved through an Interpretative Phenomenological Analysis with eight autistic women with no diagnosis of intellectual disabilities. Three core themes emerged highlighting the pervasive impact of socio-cultural values on participants, followed by how they have individualised as autistic women, and finally reflecting on the importance of staying connected with society for them. By understanding autistic women in their contexts, a more representative portrayal of their relationships with others, strengths and needs was also offered. These have implications for the continued need to shift attitudes in society through dissemination of knowledge; and clinical implications for cultivating identity development and the building of meaningful connections with society for autistic women.
RKKY interactions in the regime of strong localization

description: We study the influence of strong nonmagnetic disorder on the Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions between diluted magnetic moments in metals. We find that the probability distribution for the RKKY interactions assumes strongly non-Gaussian form featuring long tails. Since such distributions cannot be characterized by its moments, we define a \textit{typical} value of the interaction amplitude, which we find to be exponentially suppressed in presence of Anderson localization. Our results present a plausible and physically transparent picture describing how Anderson localization effectively eliminates the long range nature of the RKKY interactions.

The oscillation modes of Delta Scuti stars
Creators: name: Kennelly, Edward James
Publisher: name: University of British Columbia
Year: 2009

description: Many S Scuti stars exhibit multiperiodic oscillations and are therefore considered to be good candidates for studies in stellar seismology; the modes of oscillations act as probes of the internal stellar structure. For S Scuti seismology to be successful, both the oscifiation modes and frequencies must be determined observationaily, then compared with theoreti cal models. Standard photometric observations can provide direct information only about the frequencies of those low-degree oscillations which give rise to large disk-integrated variations. In this thesis, oscillations of both low- and high-degree were studied by ana lyzing the variations introduced in the Doppler-broadened profiles of rapidly rotating S Scuti stars. The incidence of high-degree variability within the S Scuti instability strip was inves tigated with an spectroscopic survey of ~ 50 bright stars, carried out at the Dominion Astrophysical Observatory. Evidence for high-degree variations was discovered in 14 stars which were located both on the main sequence and in more evolved stages of evolution. A few stars (e.g., [formulas]) were investigated further with high-resolution (2.4 A/mm) spectra obtained at the Canada-France-Hawaii telescope. Using a twodimensional Fourier technique to transform the variations within the line profiles in both time and Doppler space, a representation of the variations was produced from which the apparent frequency and the apparent azimuthal order (or degree) could be directly determined. The technique was especially successful at uncovering multiple modes of oscillation. The observed mode spectra were found to be consistent with prograde, sec toral modes which oscillate with nearly equal frequency in the corotating frame of the star. However, the frequencies of the high-degree modes were lower than expected if they result from pressure waves trapped near the stellar surface. To study the oscillations in detail, observations lasting several days are required in order to provide adequate frequency resolution. As part of the 1992 MUSICOS campaign, 4 days of nearly continuous observations of [symbol] Tau were obtained from sites in China, France, the Canary Islands, and Kitt Peak. Analysis of the MUSICOS data has revealed several low- and high-degree modes (l≤ 8) at frequencies between 11 and 17 cycles day⁻¹.

description: Data taken during half a year of operation of 10 LOPES antennas (LOPES-10), triggered by EAS observed with KASCADE-Grande have been analysed. We report about the analysis of correlations of radio signals measured by LOPES-10 with extensive air shower events reconstructed by KASCADE-Grande, including shower cores at large distances. The efficiency of detecting radio signals induced by air showers up to distances of 700 m from the shower axis has been investigated. The results are discussed with special emphasis on the effects of the reconstruction accuracy for shower core and arrival direction on the coherence of the measured radio signal. In addition, the correlations of the radio pulse amplitude with the primary cosmic ray energy and with the lateral distance from the shower core are studied.

description: Present experimental data from neutrino oscillations have provided much information about the neutrino mixing angles. Since neutrino oscillations only determine the mass squared differences $Δm^2_{ij} = m^2_i - m^2_j$, the absolute values for neutrino masses $m_i$ can not be determined using data just from oscillations. In this work we study implications on neutrino masses from a geometric mean mass relation $m_2=\sqrt{m_1 m_3}$ which enables one to determined the absolute masses of the neutrinos. We find that the central values of the three neutrino masses and their $2σ$ errors to be $m_1 = (1.58\pm 0.18){meV}$, $m_2 = (9.04\pm 0.42){meV}$, and $m_3 = (51.8\pm 3.5){meV}$. Implications for cosmological observation, beta decay and neutrinoless double beta decays are discussed.

Theory of correlations between ultra-cold bosons released from an optical lattice

description: In this paper we develop a theoretical description of the correlations between ultra-cold bosons after free expansion from confinement in an optical lattice. We consider the system evolution during expansion and give criteria for a far field regime. We develop expressions for first and second order two-point correlations based on a variety of commonly used approximations to the many-body state of the system including Bogoliubov, meanfield decoupling, and particle-hole perturbative solution about the perfect Mott-insulator state. Using these approaches we examine the effects of quantum depletion and pairing on the system correlations. Comparison with the directly calculated correlation functions is used to justify a Gaussian form of our theory from which we develop a general three-dimensional formalism for inhomogeneous lattice systems suitable for numerical calculations of realistic experimental regimes.

description: For a random matrix following a Wishart distribution, we derive formulas for the expectation and the covariance matrix of compound matrices. The compound matrix of order $m$ is populated by all $m\times m$-minors of the Wishart matrix. Our results yield first and second moments of the minors of the sample covariance matrix for multivariate normal observations. This work is motivated by the fact that such minors arise in the expression of constraints on the covariance matrix in many classical multivariate problems.

description: In this project we used a human neural progenitor cell line (hNPCs), whereat the cells were embedded in the synthetic self-assembling peptide hydrogel and modified formulations. Different protocols of culture conditions (2D versus 3D) were compared to analyze the neuronal differentiation and survival of the cells. The hydrogels enhance the neuronal differentiation of the hNPCs of about 2.3 fold, with an additional increase of about 2,5 fold more for the modified Scaffolds. Additionally the hNPCs were protected from apoptosis and accordingly survived longer when encapsulated in 3D scaffolds.

description: We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002cx, which has been called ``the most peculiar known type Ia supernova.'' Both supernovae exhibited high ionization SN 1991T-like pre-maximum spectra, yet low peak luminosities like SN 1991bg. The spectra reveal that SN 2005hk, like SN 2002cx, exhibited expansion velocities that were roughly half those of typical type Ia supernovae. The R and I light curves of both supernovae were also peculiar in not displaying the secondary maximum observed for normal type Ia supernovae. Our YJH photometry of SN 2005hk reveals the same peculiarity in the near-infrared. By combining our optical and near-infrared photometry of SN 2005hk with published ultraviolet light curves obtained with the Swift satellite, we are able to construct a bolometric light curve from ~10 days before to ~60 days after B maximum. The shape and unusually low peak luminosity of this light curve, plus the low expansion velocities and absence of a secondary maximum at red and near-infrared wavelengths, are all in reasonable agreement with model calculations of a 3D deflagration which produces ~0.25 M_sun of 56Ni.

description: We investigate the use of multi-agent allocation techniques on problems related to Earth observation scenarios with multiple users and satellites. We focus on the problem of coordinating users having reserved exclusive orbit portions and one central planner having several requests that may use some intervals of these exclusives. We define this problem as Earth Observation Satellite Constellation Scheduling Problem (EOSCSP) and map it to a Mixed Integer Linear Program. As to solve EOSCSP, we propose market-based techniques and a distributed problem solving technique based on Distributed Constraint Optimization (DCOP), where agents cooperate to allocate requests without sharing their own schedules. These contributions are experimentally evaluated on randomly generated EOSCSP instances based on real large-scale or highly conflicting observation order books.

We mentioned general information of Logistics, Supply Chain Management as well as the Literature review for Facility Location and for Facility Location Problems. Also, we presented some classifications of Location Facility Problems and some factors which affect the decision of where to locate the new facilities. We presented the methodology and we referred the AHP method. Furthermore, we made a reference to techniques and models. Moreover, we analyzed a real case study concerning a Greek company Cocolak with object the import, marketing and exploitation of children fun games (amusement games). Because of large number of shops in region of Chalkidiki, Company decided to find an optimal location in order to rent or to build a new or existing warehouse near there in order to reduce costs. We applied techniques and models (using software Lindo) and quoted the results of my research. We assumed that each model gives me different result because they relate to different facilities and the optimal decision for the location of a facility that ensures optimum position. Finally, quoted information for future research

description: In this paper is discussed the navigation in smart cities. More specifically is about the optimization of the apps that aim to navigate the users in these cities as long as to provide them a guided tour in historical and cultural places. As it’s mentioned in chapter 3.8 there are many apps that use similar technologies with the ones used in this paper. But they lack in common to make use of multimedia and use other new technologies. This paper deals and tries to solve this gap by proposing means to use the new technologies and upgrade the current apps. The app that has been developed in the current paper is using latest technologies in the field of mobile phones and it’s main goal is to present them to the final users. Some of these technologies are the GPS with functions as Geo-fencing, Push Notifications and Augmented Reality

description: We report optical (6 meV - 4 eV) properties of a boride superconductor ZrB$_{12}$ ($T_c$ = 6 K) in the normal state from 20 to 300 K measured on high-quality single crystals by a combination of reflectivity and ellipsometry. The Drude plasma frequency and interband optical conductivity calculated by self-consistent full-potential LMTO method agree well with experimental data. The Eliashberg function $α_{tr}^2F(ω)$ extracted from optical spectra features two peaks at about 25 and 80 meV, in agreement with specific heat data. The total coupling constant is $λ_{tr}=1.0\pm0.35$. The low energy peak presumably corresponds to the displacement mode of Zr inside $B_{24}$ cages, while the second one involves largely boron atoms. In addition to the usual narrowing of the Drude peak with cooling down, we observe an unexpected removal of about 10 % of the Drude spectral weight which is partially transferred to the region of the lowest-energy interband transition ($\sim$ 1 eV). This effect may be caused by the delocalization of the metal ion from the center of the $B_{24}$ cluster.

description: The most important direction in the development of fundamental and applied physics is the study of the properties of optical systems at the nanoscale in order to create optical and quantum computers, biosensors, single-photon sources for quantum informatics, devices for DNA sequencing, sensors of various fields, etc. In all these cases, nanoscale light sources - dye molecules, quantum dots (epitaxial or colloidal), color centers in crystals, and nanocontacts in metals - are of key importance. In the nanoenvironment, the characteristics of these elementary quantum systems - pumping rates, radiative and non-radiative decay rates, the local density of states, lifetimes, level shifts - experience changes that can be used intentionally to create nanoscale light sources with desired properties. This review presents an analysis of actual theoretical and experimental works in the field of elementary quantum systems radiation control using plasmonic and dielectric nanostructures, metamaterials, and nanoparticles made from metamaterials.

description: In an attempt to investigate the structures of ultra-relativistic jets injected into the intracluster medium (ICM) and the associated flow dynamics, such as shocks, velocity shear, and turbulence, we have developed a new special relativistic hydrodynamic (RHD) code in the Cartesian coordinates, based on the weighted essentially non-oscillatory (WENO) scheme. It is a finite difference scheme of high spatial accuracy, which has been widely employed for solving hyperbolic systems of conservation equations. The code is equipped with different WENO versions, such as the 5th-order accurate WENO-JS (Jiang & Shu 1996), WENO-Z, and WENO-ZA, and different time integration methods, such as the 4th-order accurate Runge-Kutta (RK4) and strong stability preserving RK (SSPRK), as well as the implementation of the equations of state (EOSs) that closely approximate the EOS of the single-component perfect gas in relativistic regime. In addition, it incorporates a high-order accurate averaging of fluxes along the transverse directions to enhance the accuracy of multi-dimensional problems, and a modification of eigenvalues for the acoustic modes to effectively control the carbuncle instability. Through extensive numerical tests, we assess the accuracy and robustness of the code, and choose WENO-Z, SSPRK, and the EOS suggested in Ryu et al. (2006) as the fiducial setup for simulations of ultra-relativistic jets. The results of our study of ultra-relativistic jets using the code is reported in an accompanying paper (Seo et al. 2021, Paper II).

description: We propose a device in which a sheet of graphene is coupled to a Weyl semimetal, allowing for the physical access to the study of tunneling from two-dimensional to three dimensional massless Dirac fermions. Due to the reconstructed band structure, we find that this device acts as a robust valley filter for electrons in the graphene sheet. We show that, by appropriate alignment, the Weyl semimetal draws away current in one of the two graphene valleys while allowing current in the other to pass unimpeded. In contrast to other proposed valley filters, the mechanism of our proposed device occurs in the bulk of the graphene sheet, obviating the need for carefully shaped edges or dimensions.
Modelling the trophodynamics of a coastal upwelling system

Publisher: name: University of British Columbia
Year: 2009

description: Climate variability and its influence on the northeastern Pacific Ocean is of concern to fisheries oceanographers because of the potential impacts on fish production, and management implications about fishery potential. The main objective of my dissertation is to evaluate the interactions between oceanic variability, plankton production, and fish production in a coastal upwelling system off southwestern British Columbia, Canada. A simulation model is constructed that describes the feeding interactions among diatoms, copepods, euphausiids, juvenile and adult Pacific herring (Clupea harengus pallasi), Pacific hake (Merluccius productus), chinook salmon (Oncorhynchus tshawytscha), and spiny dogfish (Squalus acanthias). The trophodynamics model is forced by empirical seasonal patterns in upwelling, sea surface temperature, solar radiation, and by observed hake and herring biomass. The most important simulation result is that there is an imbalance between fish consumption and euphausiid production during the summer upwelling season. This highlights the requirement for improved spring estimates of zooplankton biomass, evidence of euphausiid import and aggregation mechanisms, and basic life history information for the dominant euphausiid Thysanoessa spinifera. Using observed environmental data and hake and herring biomasses from 1972 to 1990, the model estimates primary production to range from 250-500 g C m⁻² y⁻¹ , secondary from 5-50 g C m⁻² y⁻¹ , and tertiary from 0.5-4.5g C m⁻² y⁻¹. Interannual and longer-term variability in plankton production occurred, with some years favouring copepod versus euphausiid production and vice versa. The trends in plankton production are determined primarily by variability in the dynamics of spring and summer upwelling. The average annual transfer efficiency (TE) of production from diatoms-to-zooplankton ranged 5-14% during 1972-90, while the 19 y average seasonal TE ranged 0-70%. Oceanic factors strongly influence euphausiid production, and ultimately the transfer of secondary production to hake and herring. Simulations also indicate that hake predation only significantly effects zooplankton production, while upwelling rate determines production at all trophic levels, from diatoms to fish. This research provides insights into how the productivity of a coastal upwelling region may respond to temporal variability in ocean climate.

description: This study aims to evaluate the effect of agricultural investment and institution on food security in 24 Sub-Saharan African (SSA) countries between 2001 and 2016. Countries are chosen based on data availability. The research employs a two-step system-GMM estimation technique to achieve the study objectives. Findings show that agricultural investment improves food security in the selected SSA countries, whereas internal and external conflicts as measures of governance positively influence food security. The study concludes that investment in agriculture and institutional quality have significant roles to play in ensuring food security in the selected countries. Thus, the study suggests further investment in the agricultural sector to boost agricultural food production, thereby ensuring food security in the selected African countries. Also, internal, and external conflict should be discouraged to ensure food security. Hence, brokering peace among citizens is very crucial to enable improved agricultural productivity, since sustainable peace would promote investment in agriculture, thereby, reducing over-reliance on food importation.

description: Abstract:Current evolutionary theory predominantly emphasizes vertical gene transmission — the inheritance of genes from parent to offspring. However, emerging evidence from microbial biology, virology, and epigenetics suggests the existence of horizontal gene influence mechanisms in more complex organisms, including humans. This manuscript proposes that evolution may also be shaped by a web of ongoing, multidirectional genetic exchanges driven by viruses, microbiota, and shared environments.

Purpose of this Manuscript:The hypothesis of “Metagenetic Evolution” challenges traditional tree-like models by introducing a lateral and ecological view of genetic development. Rather than a strict vertical lineage, this perspective suggests that organisms evolve in part through shared viral and microbial exposures — a more fluid, environmental-driven genetic landscape. The goal of this work is to ignite further interdisciplinary research and open philosophical reflection on the hidden forces that shape life.

 February 24, 2021 Gerald Roche (La Trobe University) The year 2022 will bring both an important anniversary and a new beginning. It will be the 30th anniversary of a collection of articles in the journal Language that helped consolidate and popularize the field of endangerment linguistics. And, it will also be the first year of the United Nations Decade of Indigenous Languages. This presentation will examine the intersection of these two events, in order to think through how linguists can contribute to the goals of the upcoming decade, and how they can make positive interventions in the ongoing crisis of linguistic diversity around the world more generally. I will argue that a meaningful engagement in the UN Decade, and in support of languages more broadly, will require a critical re-examination of the precedents established 30 years ago, and of the impacts that endangerment linguistics has had. In particular, I will focus on endangerment linguistics as a discourse, rather than a field of practice. I want to suggest that as a discourse, endangerment linguistics has had harmful, though largely unintended, effects that work against the aims and practices of the field. I will describe these harms and how they are produced, and discuss options for dismantling and replacing language endangerment discourses, while maintaining some of the practices and goals of the field I will also suggest that this rethinking of endangerment discourses will require sustained and good faith interdisciplinary dialog. As an anthropologist researching the intersections of race, colonialism, and language oppression, I will point out where I think some of those conversations could happen.

The horizontal effect of social rights of the Charter of Fundamen-tal Rights of the EU
Creators: name: Seifert, Achim
Publisher: name: Pro Justitia
Year: 2021

description: The question of whether the social rights of the European Charter of Fundamental Rights (ECFR) produce a horizontal effect among individuals, is one of the controversial questions in the application of the Charter. One recent example is the doctrinal debate, which has been caused by the judgment of the CJEU of 22 January 2019 (Stadt Wuppertal v Bauer et alii) entitling employees to rely on the right to paid leave under Article 31(2) ECFR in disputes between them and their employer in a field covered by EU. The purpose of the following pages is to examine this not yet satisfactorily answered question. In a first step, the author analyses whether Article 51(1) ECFR, defining “the field of application” of the Charter, addresses the question of a horizontal effect of Charter rights. In a second step, the evolution of the Court of Justice’s case law on this question is briefly outlined. And in a third and main step, the author examines, whether the social rights, enshrined in the Charter, can be directly applicable in the employment relationship (direct horizontal effect) or only have indirect effects among individuals. The argument of the author is that the ECFR is not underlying a general concept on the horizontality of its social rights. For a conceptualization, the widely recognized distinction between a direct applicability of the ECFR among individuals and its indirect effects should be the point of departure. He poses that the better arguments speak in favor of an indirect horizontal effect through the interpretation of national law and through the transposition of positive obligations resulting from the Charter rights.

The facilitation of healing for the First Nations people of British Columbia
Creators: name: McCormick, Roderick Michael
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the facilitation of healing for First Nations people living in the province of British Columbia. The purpose of the study is to develop a reasonably comprehensive scheme of categories that will describe, from the perspective of First Nations people, what facilitates healing. The research method involved interviews with 50 adult First Nations volunteers who were long-term residents of British Columbia and also in a position to observe what facilitated their own healing for them . The Critical Incident Technique (Flanagan, 1954) was utilized to elicit 437 incidents from 50 participants. Fourteen categories emerged from an analysis of the incidents reported. Several procedures were used to examine the soundness and trustworthiness of the categories. The results indicate that healing can be facilitated in the following ways: participation in ceremony, expression of emotion, learning from a role model, establishing a connection with nature, exercise, involvement in challenging activities, establishing a social connection, gaining an understanding of the problem, establishing spiritual connection, obtaining help/support from others, self care, setting goals, anchoring self in tradition, and in helping others. A preliminary examination of the healing outcomes of these facilitating events suggests that an effective healing program for First Nations people would invoke empowerment, cleansing, balance, discipline, and belonging. Narrative accounts were analyzed for the purpose of revealing an organization for the categories. Four divisions of categories emerged as a result of this analysis: separating from an unhealthy life, obtaining social support and resources, experiencing a healthy life and living a healthy life. Further analysis of the narratives revealed five overall themes which serve to enhance the categories and outcomes presented in this research. Those themes entail: A broad spectrum of healing resources are available to First Nations people, First Nations people have a different way of seeing the world which has to be understood before effective counselling services can be provided, First Nations people expect that whatever is healing should help them to attain and/or maintain balance, self transcendence followed by connectedness is a common route to healing for First Nations people, and First Nations people are seen to act as agents of their own healing. The findings of this study contribute to the field of counselling psychology by providing a reasonably comprehensive scheme of categories and themes that describe, from the perspective of First Nations people, what facilitates healing. This study suggests promising developments in First Nations healing that have implications for both research and practice.

description: Macroscopic properties of ferroelectric samples, including those in form of thin films, are, to large extent, influenced by their domain structure. In this paper the free energy is calculated for a plate-like sample composed of nonferroelectric surface layers and ferroelectric central part with antiparallel domains. The sample is provided with electrodes with a defined potential difference. The effect of applied field and its small changes on the resulting domain structure is discussed. This makes it possible to determine the restoring force acting on domain walls which codetermines dielectric and piezoelectric properties of the sample. Calculations of the potential and free energy take into account interactions of opposite surfaces and are applicable also to thin films.

description: A rotating particle in electrorheological (ER) fluid leads to a displacement of its polarization charges on the surface which relax towards the external applied field ${\bf E}_0$, resulting in a steady-state polarization at an angle with respect to ${\bf E}_0$. This dynamic effect has shown to affect the ER fluids properties dramatically. In this paper, we develop a dynamic effective medium theory (EMT) for a system containing rotating particles of finite volume fraction. This is a generalization of established EMT to account for the interactions between many rotating particles. While the theory is valid for three dimensions, the results in a special two dimensional configuration show that the system exhibits an off-diagonal polarization response, in addition to a diagonal polarization response, which resembles the classic Hall effect. The diagonal response monotonically decreases with an increasing rotational speed, whereas the off-diagonal response exhibits a maximum at a reduced rotational angular velocity $ω_0$ comparing to the case of isolated rotating particles. This implies a way of measurement on the interacting relaxation time. The dependencies of the diagonal and off-diagonal responses on various factors, such as $ω_0$, the volume fraction, and the dielectric contrast, are discussed.

description: We present a unified treatment of Zitterbewegung phenomena for a wide class of systems including spintronic, graphene, and superconducting systems. We derive an explicit expression for the time-dependence of the position operator of the quasiparticles which can be decomposed into a mean part and an oscillatory term. The latter corresponds to the Zitterbewegung. To apply our result for different systems one needs to use only vector algebra instead of the more complicated operator algebra.

(A,B) The indicated dsRNAs were used for depletion of TFs with predicted binding sites in pst_E1n. In addition, JAK/STAT signaling pathway proteins (Dome and Socs36E) and the receptor tyrosine kinase Pvr were depleted. In some cases, two dsRNA preparations (1 or 2) generated from distinct amplicons were used. lacZ ds RNA was used in two replicates (a and b). Depletions were performed in SR9rg > pst_E1n (mRuby−, GFP+) cells (A) and in SR9rg > ced-6_E (mRuby−, GFP+) cells (B). Depleted cells and control cell lines (S2R+ and SR9rg) were then shifted in aliquots to the indicated temperatures and analyzed eventually by flow cytometry. Bars display median GFP signal intensity.
Local variations of the Stellar Velocity Ellipsoid-I: the disc of galaxies in the Auriga simulations

description: The connection between the Stellar Velocity Ellipsoid (SVE) and the dynamical evolution of galaxies has been a matter of debate in the last years and there is no clear consensus whether different heating agents (e.g. spiral arms, giant molecular clouds, bars and mergers) leave clear detectable signatures in the present day kinematics. Most of these results are based on a single and global SVE and have not taken into account that these agents do not necessarily equally affect all regions of the stellar disc.We study the 2D spatial distribution of the SVE across the stellar discs of Auriga galaxies, a set of high resolution magneto-hydrodynamical cosmological zoom-in simulations, to unveil the connection between local and global kinematic properties in the disc region. We find very similar, global, $σ_{z}/σ_{r}$= 0.80$\pm$ 0.08 values for galaxies of different Hubble types. This shows that the global properties of the SVE at z=0 are not a good indicator of the heating and cooling events experienced by galaxies. We also find that similar $σ_{z}/σ_{r}$radial profiles are obtained through different combinations of $σ_{z}$ and $σ_{r}$ trends: at a local level, the vertical and radial components can evolve differently, leading to similar $σ_{z}/σ_{r}$ profiles at z=0. By contrast, the 2D spatial distribution of the SVE varies a lot more from galaxy to galaxy. Present day features in the SVE spatial distribution may be associated with specific interactions such as fly-by encounters or the accretion of low mass satellites even in the cases when the global SVE is not affected. The stellar populations decomposition reveals that young stellar populations present colder and less isotropic SVEs and more complex 2D distributions than their older and hotter counterparts.
