description: Factor Analysis (FA) and Item Response Theory (IRT) are latent variable modelling techniques with wide usage and acceptance in psychometrics, among other social sciences. Nevertheless, while their performance is optimal with normally-distributed data and latent variables and counting with corrections for non-normal data, little is known about their behavior among non-normal latent distributions. Within the variety of non-normal distributions, multimodal latent distributions are examined manipulating (1) the number of modes they present, and (2) the distance between them. By two simulation studies, results shown an incremental tendency of overestimation in parameters and latent scores while multimodality is more intense (this is, incrementing the number of modes and their distance between them). Further, fit measures were not influenced by latent variable’s multimodality in FA techniques, while IRT techniques were. Therefore, evidence shows researcher’s exposition to an apparent blindness to be modelling multimodal distributions. Even more so, parameter overestimation may lead to aberrant modelling decisions due to its desirability and publishability. Alternative models and assessment guidelines are proposed, alongside with future studies recommendations.

Les matériaux mésoporeux, opportunités pour l'industrie future
Creators: name: Brunet, Jean-Marin
Publisher: name: R&D Mediation
Year: 2014

description: Bien avant les découvertes et des développements récents, l’utilisation de matériaux poreux date de à l’Antiquité. À cette époque, les civilisations du bassin méditerrannéen utilisaient déjà certaines argiles pour nettoyer le linge, se laver, pour soulager les maux d’estomac, ou encore en agriculture (mélangé ou sol ou même comme additif alimentaire pour le bétail). L’intérêt nouveau pour ces matériaux réside dans leurs propriétés physico-chimiques modifiées pas la porosité, qui permettent de capter et intégrer certaines molécules, d’agir comme véritable catalyseur, ou permettent d’améliorer la résistance et les propriétés des polymères ou matériaux dans lesquels ils sont incorporés. L’intérêt pour ces matériaux croît considérablement lors de la seconde moitié du XXème siècle, lorsque les recherches démontrent qu’il est possible, et à faible de coût, de synthétiser des matériaux à porosité contrôlée. La possibilité de contrôler la nature, la taille et la disposition des pores représente une opportunité formidable pour les industriels de créer des matériaux sur-mesure et ainsi optimiser leurs procédés industriels. Pharmaceutiques, médicales, pétrochimiques, agroalimentaires, électroniques ou encore environnementales, nombreuses sont les industries qui doivent investir et innover pour ne pas être de simples spectateurs du progrès. Les matériaux poreux représentent, pour ces secteurs, des vecteurs de développement et de profit à ne pas négliger, d’autant que leur usage ouvre de nouvelles perspectives tout en limitant les évolutions de process à engager. Cet analyse d’opportunité est destiné à ces industries, il présente dans un premier temps les propriétés, applications, et recherches concernant des matériaux naturels et qui sont bien souvent oubliées et négligées alors qu’elles pourraient apporter de nombreuses solutions aux problématiques de gain de temps, d’efficacité et de miniaturisation auxquels les entreprises sont confrontées. Dans un second temps, cet ouvrage présente certaines des avancées les plus récentes dans la synthèse des matériaux micro et mésoporeux, et présente leur très large champ d’application. Il vise, au travers d’une vingtaine de matériaux et plus de 150 références bibliographiques, à susciter des idées à l’entrepreneur qui souhaite innover, ou au contraire à ne pas négliger un virage technologique majeur dans son secteur.

Publisher: name: Zenodo
Year: 2018

description: The James Webb Space Telescope (JWST) is due for launch in 2020. Optimized for near to mid-infrared wavelengths, it is the largest telescope ever put in space. One of the main science drivers is understanding star and planet formation: thus the study of outflows and disks is central not only to the JWST guaranteed time program but will also be the focus of many open time proposals. After briefly reviewing the four main instruments: NIRCAM, NIRSPEC, NIRISS and MIRI, the broad goals of the star and planetary formation guaranteed time programs will be outlined including the study of chemical processes in the inner disk, the effects of metallicity on accretion, and the atomic and molecular properties of embedded outflows.

Exploring The Time Evolution Of Cool Metallic Absorption Features In Uv Burst Spectra
Creators: name: Belmes, Kimberley B.
Publisher: name: Zenodo
Year: 2017
Subjects: Solar activity
Solar chromosphere

description: UV bursts are compact brightenings in active regions that appear in UV images. They are identified through three spectroscopic features: (1) broadening and intensification of NUV/FUV emission lines, (2) the presence of optically thin Si IV emission, and (3) the presence of absorption features from cool metallic ions. Properties (2) and (3) imply that bursts exist at transition region temperatures (≥ 80,000 K) but are located in the cooler lower chromosphere (~ 5,000 K). Their energetic and dynamical properties remain poorly constrained. Improving our understanding of this phenomena could help us further constrain the energetic and dynamical properties of the chromosphere, as well as give us insight into whether or not UV bursts contribute to chromospheric and/or coronal heating. We analyzed the time evolution of UV bursts using spectral data from the Interface Region Imaging Spectrograph (IRIS). We inspected Si IV 1393.8 Å line profiles for Ni II 1393.3 Å absorption features to look for signs of heating. Weakening of absorption features over time could indicate heating of the cool ions above the burst, implying that thermal energy from the burst could rapidly conduct upward through the chromosphere. To detect the spectral profiles corresponding to bursts, we applied a four-parameter Gaussian fit to every profile in each observation and took cuts in parameter space to isolate the bursts. We then manually reviewed the remaining profiles by looking for a statistically significant appearance of Ni II 1393.3 Å absorption. We quantified these absorption features by normalizing the Si IV 1393.8 Å emission profiles and measuring the maximum fractional extinction in each. Our preliminary results indicate that Ni II 1393.3 Å absorption may undergo a cycle of strengthening and weakening throughout a burst’s lifetime. However, further investigation is needed for confirmation.

First disk-mediated accretion burst from a massive proto(star): how accretion turns into ejection
Creators: name: Caratti o Garatti, Alessio
Publisher: name: Zenodo
Year: 2018

description: How massive stars form and evolve in their early phase is still debated. Here, we report on the discovery and follow-up of the first disk-mediated accretion burst from a 20 solar mass protostar, S255IR NIRS3. Our results strengthen the idea that massive stars form through disks via episodic accretion, pointing to a common formation mechanism across the entire stellar mass spectrum. Moreover, our data reveal a tight correlation between the burst, the onset of a methanol maser flare and boosting of pre-existent radio jet emission.

Accretion variability in young, low mass stars
Creators: name: Venuti, Laura
Publisher: name: Zenodo
Year: 2018

description: We present and discuss the manifold photometric behaviors of young, low-mass stars with active accretion disks. This review is based on results from recent space-borne missions, most notably CoRoT and Kepler/K2. Thanks to their sub-1% photometric precision, sub-hour time sampling, and continuous time coverage for spans of weeks to months, these campaigns have provided first detailed atlases of the short- to mid-term variability of young, disk-bearing stars. Distinct variability types identified include the bursters (with stochastic, short-lived brightening events), the dippers (with recurring or aperiodic fading events), and the quasi-periodic variables. The first class likely reflects unstable disk accretion, with strong mass accretion rates (M_acc), as suggested by complementary UV observations. The other two photometric classes may instead be related to a stable, funnel-flow accretion regime, with more moderate M_acc. While the strength of M_acc variability can vary broadly from object to object, typical M_acc variations amount to <0.1 dex on timescales of hours, and to ~0.5 dex on timescales of days to weeks; the latter persist on timescales of up to several years. Geometric effects linked to rotational modulation can statistically explain a significant fraction (up to 75%) of the observed M_acc variability. This suggests that the global accretion geometry in young stars typically persists over many rotational cycles, although single accretion events may exhibit more erratic behavior on the shorter term.

On The Secular Evolution of GG Tau A Circumbinary Disc: A Misaligned Disc Scenario
Creators: name: Hossam, Aly
Publisher: name: Zenodo
Year: 2018

description: The binary system GG Tau A is observed to have a circumbinary disc with a

dust ring located further out than expected from tidal truncation theory.

Given the binary separation, this large cavity can be explained by relaxing

the assumption of a co-planar disc and instead fit the observations with a

mis-aligned circumbinary disc around an eccentric binary with a wider

semi-major axis. I present the results of SPH simulations to check this

possibility and investigate the long term evolution of such a system. I

find that a misalignment angle of 30 degrees and a binary eccentricity of

0.45 fit both the astrometric data and the disc cavity.

description: Amblyopone impressifrons (Emery)
Stigmatomma impressifrons Emery, 1869, Ann. Accad. Aspir. Natur., Napoli, 13, tav. 1, fig. 8. [[worker]] e [[queen]].
Capodimonte (Napoli).
Operaia (fig. 2 e 8): Differisce da A. denticulata per una importante serie di caratteri il piu vistoso dei quali e certamente rappresentato dalla taglia molto maggiore. Inoltre, il capo e piu largo in avanti e proporzionalmente piu corto, spine genali piu pronunciate, lamine frontali piu distanziate, funicolo a primi antennomeri allungati, occhi piu grandi. Formula palpale 5: 3. Presenza di un paio di spine metasternali ben sviluppate medialmente e cranialmente all'inserzione del terzo paio di coxe. Prominenza ventrale del peziolo piu stretta e piu aggettante, con un accenno di fenestra. Microscultura tegumentale piu marcata e piu regolare.
Lunghezza totale (secondo Emery) 6,0 - 7,5 mm. Lunghezza totale dell'esemplare da me esaminato, mandibole escluse, 5,8 mm.
Dimensioni in mm ed indici: Lc 1,21; lc 1,29; Lsc 0,79; Lp 0,61; lp 0,66; IC 106,6; ISC 65,3; IP 108,2.
Materiale esaminato: Una sola operaia paratipica di Capodimonte (Napoli) (MHNG).
Osservazioni: Questa specie e nota da diverse localita italiane tra l' Emilia e la Sicilia (comprese). Baroni Urbani (1971) ne da un elenco completo. Emery (1909) la cita anche per la prima volta della Grecia, pur senza ulteriori specificazioni, e questa segnalazione e stata poi riportata in numerosi altri cataloghi e monografie. Il fatto che questa specie non sia piu stata ritrovata in questa regione e che essa non sia rappresentata nel copioso materiale di provenienza greca esaminato nel corso di questo studio, permette di avanzare qualche dubbio sull'autenticita del reperto.
La presenza delle due vistose spine metasternali non era mai stata notata in precedenza per questa specie e tale carattere e tanto insolito nelle formiche che si potrebbe essere tentati di creare un genere monotipico per la sola A. impressifrons. L'habitus generale e tutti gli altri caratteri sono pero cosi palesemente di tipo Amblyopone che una soluzione di questo genere non sembra necessaria al momento. Converra ricordare in proposito che A. impressifrons presenta anche il piu alto conteggio del numero di articoli dei palpi mascellari finora noto in questo genere.

СOMPARATIVE ANALYSIS OF THE PROCESSES OF DIGITALIZATION OF THE ECONOMIES OF SOUTH KOREA AND TURKEY

Year: 2024

description: The digitalization processes of South Korea and Turkey have both been significant, but they have some differences. South Korea has been a global leader in digitalization, with a highly advanced and tech-savvy economy. The country has invested heavily in infrastructure, research and development, and education to foster digital innovation. South Korea's government has also played a key role in promoting digitalization through policies and initiatives. On the other hand, Turkey has also been actively pursuing digitalization, but its progress has been influenced by different factors. Turkey has a large and young population, which has contributed to the rapid adoption of digital technologies. The government has implemented various programs to improve digital infrastructure and increase internet penetration across the country. However, compared to South Korea, Turkey's digitalization efforts may still be in earlier stages, with a focus on expanding access to digital services and promoting digital entrepreneurship. In summary, while both South Korea and Turkey have made strides in digitalization, South Korea stands out as a more advanced and mature digital economy, while Turkey's digitalization efforts may still be evolving.

Stigmatomma normandi Santschi, 1915, Bull. Soc. Hist. Nat. Afr. Nord, 7: 54. [[worker]]. Le Kef e Sousse (Tunisia).
Operaia (fig. 4 e 10): Capo stretto ed allungato a lati subparalleli ed occipite quasi diritto. Angoli anteriori debolmente prominenti. Clipeo a margine anteriore armato di sette tubercoli di cui i due esterai notevolmente incrassati. Occhi nulli. Antenne a scapo sottile e debolmente curvato. Funicolo ad antennomeri 2 - 6 subeguali. Mandibole strette ed allungate, regularmente armate di una serie di otto denti; il 2°, 3° e 4° mediano sono associati ad un minuscolo denticolo in posizione esterna. Formula palpale 4: 2. Alitronco a profilo molto debolmente gibboso, interrotto solo in corrispondenza della sutura promesonotale. Sutura mesoepinotale indistinguibile anche sulle pleure. Epinoto a faccia superiore pianeggiante lunga circa due volte quanto quella discendente. Spine metasternali assenti. Peziolo a lati arcuati, ancora piu tondeggianti che in A. ophthalmica. Per il resto, eguale a questa specie.
Tegumento lucidissimo, interrotto soltanto da fossette piligere poco profonde sul capo che sono quasi del tutto indistinguibili suU'alitronco. Nessuna traccia di striatum vera e propria ad eccezione di alcune deboli strie longitudinali sulle mandibole e, in qualche esemplare, minutissime corrugazioni trasversali sull'occipite.
Pochi e brevi peli suberetti o subdecumbenti sparsi su gran parte della superficie corporea. Setole leggermente piu lunghe attorno alla regione anale.
Colorito giallo testaceo (in esemplari neosfarfallati?) o bruno, sempre molto lucido.
Lunghezza totale, escluse le mandibole 2,7 - 3,5 mm.
Dimensioni in mm ed indici: Lc 0,63 - 0,80; lc 0,55 - 0,66; Lsc 0,40 - 0,54; Lp 0, 28 - 0,38; lp 0,31 - 0,35; IC 106,8 - 126,7; ISC 61,8 - 77,8; IP 84,2 - 116,7.
Materiale esaminato: 8 [[worker]] [[worker]] di Sousse (7 NHMB e 1 CK) e 2 di Le Kef (tutti in Tunisia e leg. Normand, NHMB). Benche quello qui citato debba rappresentare grosso modo tutto il materiale visto dal Santschi all'epoca della descrizione originale, solo 3 [[worker]] [[worker]] di Sousse portano Petichetta tipo scritta di pugno dell'autore (NHMB Nr. XXI. V. a. 65). Quattro [[worker]] [[worker]] di Ginosar (Galilea, 24. V. 73,1. Loebl leg.) (MHNG e NHMB).
Osservazioni: La specie e nota solo dalle localita qui citate. Gli esemplari di Galilea sono sensibilmente piu piccoli di quelli di Tunisia (ad esempio, Tunisia Lc> 0,75 e Galilea Lc <0,66), ma tale differenza scompare quasi del tutto negli indici (Tunisia IC> 116 e Galilea IC <115) e ritengo che potra venire del tutto annuUata con la raccolta di un materiale piu abbondante.

Year: 2024

description: Cet article théorique se propose d'analyser les fondements des valeurs chez les entrepreneurs sociaux, mettant en lumière leur influence sur la nature et la direction des entreprises à vocation sociale. En s'appuyant sur l'élan mondial en faveur de l'entrepreneuriat social et son intégration croissante avec le secteur coopératif, cette étude examine les dynamiques conceptuelles sous-jacentes, sans se focaliser sur une partie pratique. Nous débutons par une exploration des différentes perspectives de l'entrepreneuriat social, soulignant son émergence en tant que discipline distincte au sein du paysage entrepreneurial contemporain. Ensuite, nous plongeons dans une analyse approfondie du lien entre les valeurs et la réussite des projets entrepreneuriaux sociaux, en adoptant une approche conceptuelle et théorique. L'objectif est de fournir une compréhension approfondie des mécanismes sous-jacents qui façonnent les valeurs des entrepreneurs sociaux et leur impact sur leurs initiatives.

description: Amblyopone gaetulica n. sp.
Operaia (fig. 6 e 12): Capo subrettangolare non molto ristretto all'indietro ed a lati poco arcuati. Angoli genali prominenti. Lamine frontali relativamente distanti fra loro. Occhi minutissimi ma presenti. Antenne a scapo moderatamente allungato e funicolo ad antennomeri 2 - 5 poco piu iunghi che larghi. Mandibole regularmente armate di otto denti ma il basale ed i primi due medidi sono semplici. Il terzo mediale e associato ad un denticolo minore, mentre il quarto ed il quinto mediale sono esattamente sdoppiati. Formula palpale 4: 3.
Alitronco a dorso diritto e piatto, sensibilmente interrotto in corrispondenza delle suture promesonotale e mesoepinotale. Mesonoto debolmente separato dalla mesopleura per mezzo di un accenno di sutura. Spine metasternali assenti. Peziolo molto largo, a dorso subquadrato e leggermente convesso. Sporgenza ventrale con il solito lobo prominente in avanti e con un marcato accenno di lobo posteriore. Fenestra obsoleta.
Microscultura circolare piuttosto densa ed intervallata da deboli corrugazioni del tegumento su tutto il capo. La stessa struttura, meno accentuata, si riscontra anche su tutto Palitronco ed il peziolo per scomparire poi definitivamente sul gastro. Epipleure e mandibole debolmente striate in senso longitudinale.
Alcuni peli eretti relativamente lunghi su quasi tutta la superficie corporea. Colore bruno molto lucido con le appendici piu chiare. Lunghezza totale escluse le mandibole 3,5 mm.
Dimensioni in mm ed indici: Lc 0,76; lc 0,69; Lsc 0,44; Lp 0,33; lp 0,43; IC 90,8; ISC 57,9; IP 130,3.
Materiale esaminato: Un solo esemplare (olotipo) di Tangeri (Marocco), III. 1896 (ex Musaeo H. Vaucher) (NHMB Nr. XXI. V. a. 63).
Osservazioni: Questo esemplare, originariamente etichettato dal Santschi come« Stigmatomma emeryi Saunders type», e stato poi incluso nella collezione Santschi con il nome di Stigmatomma gaetulicum Santschi 1940 e non e mai stato descritto. La specie e separabile a colpo d'occhio da A. emeryi per la diversa scultura del capo. Per contro puo insultare difficilmente distinguibile da A. denticulata dell'Europa meridionale, da cui differisce purtuttavia per la dentazione delle mandibole, unica fra tutte le specie da me esaminate, per la conformazione del lobo ventrale del peziolo e per i valori dell'IP (A. denticulata IP <120; A. gaetulica IP> 130). E verosimile che almeno parte delle vecchie segnalazioni di A. denticulata per il Maghreb debbano, in realta, essere riferite a questa specie.

Operaia (fig. 13 e 14): Capo subtrapezoidale, molto piu largo in avanti che all'indietro e con i lati sensibuemente curvati. Occipite debolmente incavato. Lamine frontali estremamente ravvicinate e divergenti verso Poccipite. Linea frontale ben marcata ed ininterrotta prolungantesi fino al bordo posteriore del capo. Clipeo a margine anteriore armato di otto denticoli prominenti. Angoli genali relativamente smussati. Antenne di 11 articoli a scapo corto: ripiegato all'indietro esso dista dal margine occipitale oltre 1 / 3 della sua lunghezza. Occhi assenti. Mandibole con il margine interno armato di quattro denticoli semplici e ricurvi all'indietro. Margine masticatorio vero e proprio con tre grossi denti che possono venire rispettivamente interpretati come un basde, un apicale ed un preapicde piu piccolo.
Alitronco piatto dorsdmente, interrotto solo dalla sutura promesonotale sul profilo. Sutura mesoepinotale del tutto assente. Mesonoto separato dalla mesopleura per mezzo di una sutura marcata. Peziolo corto e molto largo. Sporgenza ventrale prominente in avanti e senza accenno di fenestra.
Microscultura tondeggiante piuttosto marcata con superimposizione di deboli strie, uniformemente sparsa su tutto il capo e l'ditronco. La medisima struttura, meno accentuata, si ritrova anche sul peziolo e sul primo somite del gastro, mentre si indebolisce fino quasi a scomparire sugli ultimi somiti addominali. Appendici molto debolmente scolpite e sublucide.
Una breve pubescenza ispida e suberetta e sparsa su quasi tutta la superficie corporea. Colore giallo bruno abbastanza uniforme, leggermente piu chiaro sulle zampe.
Lunghezza totale senza le mandibole, 2 mm circa.
Dimensioni in mm ed indici: Lc 0,53; lc 0,54; Lsc 0,28; Lp 0,21; lp 0,29; IC 101,9; ISC 52,8; IP 138,1.
Materiale esaminato: Un solo esemplare (olotipo) di Chim Khona presso Ghum, 2200 m, 28. V. 75, al vaglio, W. Wittmer leg. (India, distretto di Darjeeling) (NHMB Nr. XXI. V. a. 873).
Osservazioni: Questa specie, che rappresenta il reperto piu settentrionale del genere nell' Asia centrale ed il record altimetrico del genere su scala mondiale, non ha alcuna affinita con le specie precedentemente note del subcontinente indiano, ma ricorda abbastanza da vicino A. minuta (Forel), endemico di Sumatra. A. pertinax differisce purtuttavia da questa specie per numerosi importanti caratteri tra cui bastera citare il minore sviluppo dei denti basale ed apicale nella specie di Sumatra, i denticoli del margine interno delle mandibole semplici in A. pertinax e doppi in A. minuta, IC 101,9 (A. pertinax) e IC 83,3 (in entrambi i sintipi di A. minuta da me esaminati).

description: The pleomorphic adenoma gene 1 (Plag1) is a transcription factor involved in the regulation of growth and cellular proliferation. Here, we report the spatial distribution and functional implications of PLAG1 expression in the adult mouse brain. We identified Plag1 promoter-dependent β-galactosidase expression in various brain structures, including the hippocampus, cortex, choroid plexus, subcommisural organ, ependymal cells lining the third ventricle, medial and lateral habenulae and amygdala. We noted striking spatial-restriction of PLAG1 within the cornu ammonis (CA1) region of the hippocampus and layer-specific cortical expression, with abundant expression noted in all layers except layer 5. Furthermore, our study delved into the role of PLAG1 in neurodevelopment, focusing on its impact on neural stem/progenitor cell proliferation. Loss of Plag1 resulted in reduced proliferation and decreased production of neocortical progenitors in vivo, although ex vivo neurosphere experiments revealed no cell-intrinsic defects in the proliferative or neurogenic capacity of Plag1-deficient neural progenitors. Lastly, we explored potential target genes of PLAG1 in the cortex, identifying that Neurogenin 2 (Ngn2) was significantly downregulated in Plag1-deficient mice. In summary, our study provides novel insights into the spatial distribution of PLAG1 expression in the adult mouse brain and its potential role in neurodevelopment. These findings expand our understanding of the functional significance of PLAG1 within the brain, with potential implications for neurodevelopmental disorders and therapeutic interventions.

description: Die vorliegende Arbeit entspringt dem Forschungsfeld der Impact-Forschung, einem Teilprojekt der Zitations-Rezeptions-Diskursforschung (ZRD). Die ZRD wiederum ist der bildungswissenschaftlichen Disziplin zugehörig, woraus für die Arbeit ein zwei-strängiges Forschungsvorhaben resultiert: Mit der Frage nach dem Einfluss wissenschaftlicher Literatur auf die pädagogische Praxis im Rahmen der scientific community der Individualpsychologie, versucht die Arbeit einerseits theoretische und praktische Aspekte der Pädagogik einander näher zu bringen und verfolgt dabei das Ziel einer Beitragsleistung für die Disziplin der Bil-dungswissenschaft. Gleichzeitig bemüht sich die Forschungsarbeit auch um die Wei-terentwicklung der Impact-Forschung und betritt bei der Erhebung besagten „Impacts in der Praxis“ methodisches Neuland in der Impact-Forschung und damit einhergehend in der ZRD. Als Pilotstudie ausgewiesen, wird Impact erstmals außerhalb der Analyse des Gegenstandes „Text“, nämlich mit der Datenerhebung durch qualitative Interviews ermittelt.
description: This thesis can be placed within the field of impact research, a subproject of the Cita-tion-Reception-Discourse Research, which belongs to the discipline of Educational Science. Therefore, this thesis has a dual research project. First, it investigates the in-fluence of scientific literature on the pedagogical praxis within the framework of the scientific community of individual psychology. It thus aims at bringing theoretical and practical aspects of pedagogy closer together in order to contribute to the field of Edu-cational Science. Second, this thesis enhances the field of impact research with new methodologies in regards to both impact research and Citation-Reception-Discourse Research by gathering data of “impacts in the praxis”. Declared as a pilot study, impact is, for the first time, considered outside of the analysis of its “text” by the data collection of qualitative interviews.
Dark Matter reconstruction from stellar orbits in the Galactic Centre

description: Context. Current constraints on distributed matter in the innermost Galactic Centre (such as a cluster of faint stars and stellar remnants, Dark Matter or a combination thereof) based on the orbital dynamics of the visible stars closest to the central black hole, typically assume simple functional forms for the distributions. Aims. We take instead a general model agnostic approach in which the form of the distribution is not constrained by prior assumptions on the physical composition of the matter. This approach yields unbiased - entirely observation driven - fits for the matter distribution and places constraints on our ability to discriminate between different density profiles (and consequently between physical compositions) of the distributed matter. Methods. We construct a spherical shell model with the flexibility to fit a wide variety of physically reasonable density profiles by modelling the distribution as a series of concentric mass shells. We test this approach in an analysis of mock observations of the star S2. Results. For a sufficiently large and precise data set, we find that it is possible to discriminate between several physically motivated density profiles. However, for data coming from current and expected next generation observational instruments, the potential for profile distinction will remain limited by the precision of the instruments. Future observations will still be able to constrain the overall enclosed distributed mass within the apocentre of the probing orbit in an unbiased manner. We interpret this in the theoretical context of constraining the secular versus non-secular orbital dynamics.
