description: (119951) 2002 KX14 is a large classical TNO with limited previous observations and unresolved questions regarding its physical properties. Five stellar occultations by 2002 KX14 were observed from 2020 to 2023, involving multiple telescopes across different locations in Europe and the Americas. The five occultations resulted in 15 positive chords, accurately measuring the 2002 KX14's shape and size. The projected ellipse has semi-major and semi-minor axes of $241.0 \pm 7.2$ km and $157.1 \pm 5.2$ km, respectively, corresponding to an average area-equivalent diameter of $389.2 \pm 8.7$ km. The geometric albedo was estimated at $11.9 \pm 0.7\%$.

description: We introduce an updated version of our deep learning tool that predicts stellar parameters from the optical spectra of young low-mass stars with intermediate spectral resolution. We adopt a conditional invertible neural network (cINN) architecture to infer the posterior distribution of stellar parameters and train our cINN on two Phoenix stellar atmosphere model libraries (Settl and Dusty). Compared to the cINNs presented in our first study, the updated cINN considers the influence of the relative flux error on the parameter estimation and predicts an additional fourth parameter, veiling. We test the performance of cINN on synthetic test models to quantify the intrinsic error of the cINN as a function of relative flux error and on 36 class III template stars to validate the performance on real spectra. Using our cINN, we estimate the stellar parameters of young stars in Trumpler 14 (Tr14) in the Carina Nebula Complex, observed with VLT-MUSE, and compare them with those derived using the classical template fitting method. We provide Teff, log g, Av, and veiling values measured by our cINN as well as stellar ages and masses derived from the HR diagram. Our parameter estimates generally agree well with those measured by template fitting. However, for K- and G-type stars, the Teff derived from template fitting is, on average, 2-3 subclasses hotter than the cINN estimates, while the corresponding veiling values from template fitting appear to be underestimated compared to the cINN predictions. We obtain an average age of 0.7(+3.2)(-0.6) Myr for the Tr14 stars. By examining the impact of veiling on the equivalent width-based classification, we demonstrate that the main cause of temperature overestimation for K- and G-type stars in the previous study is that veiling and effective temperature are not considered simultaneously in their process.

description: We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the combination of multiple messengers. This is framed by gravitational lensing phenomenology that has grown since the first discoveries in the 20th century, messengers that span 30 orders of magnitude in energy from high energy neutrinos to gravitational waves, and powerful "survey facilities" that are capable of continually scanning the sky for transient and variable sources. Within this context, the main focus is on discoveries and science that are feasible in the next 5-10 years with current and imminent technology including the LIGO-Virgo-KAGRA network of gravitational wave detectors, the Vera C. Rubin Observatory, and contemporaneous gamma/X-ray satellites and radio surveys. The scientific impact of even one multi-messenger gravitational lensing discovery will be transformational and reach across fundamental physics, cosmology and astrophysics. We describe these scientific opportunities and the key challenges along the path to achieving them. This article is the introduction to the Theme Issue of the Philosophical Transactions of The Royal Society A on the topic of Multi-messenger Gravitational Lensing, and describes the consensus that emerged at the associated Theo Murphy Discussion Meeting in March 2024.

description: The fundamental non-Hermitian nature of the forms of coupled-cluster (CC) theory widely used in quantum chemistry has usually been viewed as a negative, but the present letter shows how this can be used to advantage. Specifically, the non-symmetric nature of the reduced one-particle density matrix (in the molecular orbital basis) is advocated as a diagnostic indicator of computational quality. In the limit of full coupled-cluster theory (which is equivalent to full configuration interaction (FCI)), the electronic wavefunction and correlation energy are exact within a given one-particle basis set and the symmetric character of the exact density matrix is recovered. The extent of the density matrix asymmetry is shown to provide a measure of ``how difficult the problem is'' (like the well-known T$_1$ diagnostic), but its variation with level of theory also gives information about ``how well this particular method works'', irrespective of the difficulty of the problem at hand. The proposed diagnostic is described and applied to a select group of small molecules, and an example of its overall utility for the practicing quantum chemist is illustrated through its application to the beryllium dimer (Be$_2$). Future applications of this idea to excited states, open-shell systems, symmetry-breaking problems and extension of the method to the two-particle density are then proposed.

description: [Abridged] SFGs are the dominant population in the faint radio sky, corresponding to flux densities at 1.4 GHz $< 0.1$ mJy. A panchromatic approach is essential for selecting SFGs in the radio band and understanding star formation processes over cosmic time. Semi-empirical models are valuable tools to effectively study galaxy formation and evolution, relying on minimal assumptions and exploiting empirical relations between galaxy properties and enabling us to take full advantage of the recent progress in radio and optical/near-infrared (NIR) observations. In this paper, we develop the Semi-EMPirical model for Extragalactic Radio emission (SEMPER) to predict radio luminosity functions and number counts at 1.4 GHz and 150 MHz for SFGs. SEMPER is based on state-of-the-art empirical relations and combines the redshift-dependent galaxy stellar mass functions obtained from the recent COSMOS2020 catalogue, which exploits deep near-infrared observations, with up-to-date observed scaling relations, such as the galaxy main sequence and the mass-dependent far-infrared/radio correlation across cosmic time. Our luminosity functions are compared with recent observational determinations from several radio telescopes, along with previous semi-empirical models and simulations. Our semi-empirical model successfully reproduces the observed luminosity functions at 1.4 GHz and 150 MHz up to $z\sim 5$ and the most recent number count statistics from radio observations in the LoTSS deep fields. Our model, based on galaxies selected in the NIR, naturally predicts the presence of radio-selected massive and/or dust-obscured galaxies already in place at high redshift ($z\gtrsim3.5$), as suggested by recent results from JWST. Our predictions offer an excellent benchmark for upcoming updates from JWST and future ultra-deep radio surveys planned with the SKA and its precursors.

description: We establish a spherically symmetric model of solar atmosphere, which consists of the whole chromosphere and low corona below the $1.25$ solar radius. It is a hydrodynamic model with heating in the chromosphere through an artificial energy flux. We performed a series of simulations with our model and found oscillations with a peak frequency of $\sim$4 $\rm{mHz}$ in the power spectrum. We confirmed that this resulted from the $p$-mode excited in the transition region and amplified in a resonant cavity situated in the height range $\sim$$4\times10^3$--$2\times10^4$ km. This result is consistent with global observations of Alfvénic waves in corona and can naturally explain the observational ubiquity of $4\ \rm{mHz}$ without the difficulty of the $p$-mode passing through the acoustic-damping chromosphere. We also confirmed that acoustic shock waves alone cannot heat the corona to the observed temperature, and found mass upflows in the height range $\sim$$7\times10^3$--$7\times10^4$ km in our model, which pumped the dense and cool plasma into the corona and might be the mass supplier for solar prominences.

description: Long Period radio Transients (LPTs) are a mysterious new class of radio transients pulsating on periods of minutes to hours. So far, eight LPTs have been discovered predominantly at low Galactic latitudes, yet their nature remains unknown. Here, I present the first phase-resolved optical spectroscopy of the 2.9-h LPT GLEAM-X J0704-37, acquired with the 10-m Keck I telescope. Radial velocity (RV) shifts of $189\pm 3 \textrm{km s}^{-1}$ of an M5-type star in a binary system are detected on a period nearly equal to the radio period. Weak H$α$ emission is also present, with some of it possibly originating from outside of the M dwarf. Based on the RV amplitude, and assuming a typical M dwarf mass, the companion mass must be $M \geq 0.22 M_\odot$. Calibrating the spectra with space-based \textit{Gaia} photometry reveals that the system is nearly four times closer than previously reported, at $d \approx 400$ pc, suggesting that more systems could be nearby and amenable to optical characterization. The optical spectrum between 3500-10,000 Angstrom is well modeled by a binary comprised of a massive white dwarf (WD; $T_\textrm{eff}\approx$7,300 K, $M\approx0.8-1.0M_\odot$) and M dwarf ($T_\textrm{eff}\approx$3,000 K, $M\approx0.14M_\odot$). Radio pulses arrive when the WD is at nearly maximum blueshift and the M dwarf at nearly maximum redshift, in contrast to what has been reported in a similar LPT, ILT J1101+5521. GLEAM-X J0704-37 is now the second LPT with an orbital period nearly equal to the radio period, hinting at two classes of LPTs: ``long LPTs'' ($P\gtrsim$78 min) associated with WD + M dwarf binary orbits, and ``short LPTs'' ($P\lesssim$78 min) related to WD or neutron star spins. This work demonstrates that precise localization of LPTs, which enables optical follow-up, will be key in uncovering the mechanism(s) that power this new class of phenomenon.

description: We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF and ASAS-SN) surveys. From the observed data, we find that the lens system is located at a distance of 1 kpc and comprises an M-dwarf host star of about half a solar mass, orbited by a Jupiter-like planet beyond the snowline. The source star could be a metal-poor giant located in the halo according to the spectral analyses and modelling. Hence, AT2021uey is a unique example of the binary-lens event outside the bulge that is offered by a disc-halo lens-source combination.

description: We explore the massive cluster XMMXCS J2215.9-1738 at z about 1.46 with MUSE and KMOS integral field spectroscopy. Using MUSE spectroscopy we traced the kinematics of the ionized gas using [OII] in the central 500x500 square kpc area of the cluster, which contains 28 spectroscopically identified cluster galaxies. We detected [OII] emission lines in the integrated spectra of 21 galaxies. The remaining seven are passive galaxies. Six of these passive galaxies lie in the central part of the cluster, which has a diameter of 200 kpc and which contains no star-forming objects. In this place star-formation in galaxies is quenched. An interesting discovery in this central area of the cluster are three diffuse ionized [OII] gas structures, which we refer to as [OII] blobs. They extend over areas of some hundred square kpc. The ionization source of one of the gaseous structures that displays two prominent filamentary patterns indicating outflow of gas is an active galactic nucleus (AGN). The KMOS data enabled us to use the BPT diagram to identify this object as a type 2 AGN. The other two diffuse ionized oxygen gaseous structures are more enigmatic. They are located between the stellar components of passive cluster galaxies. One of these blobs lacks a stellar counterpart in the HST optical and near-infrared data, and the other blob has only a very faint counterpart. Ram-pressure stripping of photoionized gas or AGN feedback might be an explanation. Additionally, the galaxy velocity distribution in this high-redshift cluster is bimodal, which indicates that the cluster is probably not fully virialized and that recent and ongoing merging events that produced shocks might provide photoionization sources for the two enigmatic [OII] blobs.

Debt, bubble policy, and the role of the repo market in the Federal Reserve’s management of capitalism in crisis

Monetary policy

description: In the last decade, repurchase-agreements (repos) between banks and financial institutions have grown significantly as banks systemically low on cash see repos as the cheapest, safest, and quickest way to get the funding they need for running regular services. However, hikes in interest rates by the Federal Reserve since March 2022 have increased the cost of interbank borrowing. This causes stress on many banks, and ultimately, brings into question the financial system’s long-term reliance on repos and other obscure short-term funding methods. Awareness of the Fed’s repo market policy, and their monetary policy in general, ought to matter to political economists and workers alike because it reveals precisely how the economy is controlled by a few levers inside the marriage between state and finance capital. Consequently, in this article I outline the repo market and its significance to the Fed’s management of economic crises. This requires a relative understanding of their general monetary policy, which in itself requires significant material economic contextualizing. It is this context that ultimately matters most, and which will therefore be the focal point of discussion. Only after such contextualization does the discussion end with a word on the rise of repos, the risks of increased reliance on it, and possible future directions from the perspective of both capital and labor.
Mule deer winter range : managing for a broader range of values
Creators: name: Melnick, Anthony
Publisher: name: The University of British Columbia
Year: 2013

description: Mule deer winter range (MDWR) management aims to produce a forest with a tree species composition that favours Douglas-fir. Removing spruce, lodgepole pine, and deciduous components of the stand is the standard practice used on these ranges to increase the proportions of Douglas-fir. Large diameter Douglas-fir are especially favoured because they increase the stands ability to intercept snow. The optimal stand structure on a MDWR is a multi layered uneven aged stand. These management strategies can provide very effective snow interception that reduces the snow depth on the ground. Keeping the stand structure also is beneficial for many wildlife species. However, managing for MDWR in this way does not address a number of other issues such as fuel loading, forest health, tree species diversity, and some other wildlife species.
Coastal British Columbia log exports : policy review and analysis
Creators: name: Plavetic, Michael
Publisher: name: The University of British Columbia
Year: 2013

description: Log exports have been an important issue for the forest industry of coastal British Columbia, which is the source of a majority of the province’s log exports. They account for a relatively small proportion of the province’s annual harvest, normally less than 5%, yet garner a lot of attention from the government, industry and the public. British Columbia log export policies were first enacted in 1891. Policies were introduced to restrict log exports in order to promote the development of the domestic manufacturing industry. Surplus to domestic manufacturing has been the main criterion for receiving an export permit since the government introduced exemptions to the restrictions in 1901. Log export volumes tend to increase during recessionary times to stimulate economic activity in the forest industry and normally rise and fall inversely with the demand for manufactured wood products. In 1995 the largest importer of forest products from coastal British Columbia, Japan, went into recession. Following that, Japanese builders moved away from the use of hemlock lumber when new building codes were introduced there. This caused lumber exports to Japan to collapse and the price of hemlock, which makes up 60% of the inventory on the coast, to go down by almost half in three years. The coastal forest industry has been struggling since then. The volume of logs exported from the coast has increased dramatically from the lows of 1997 and many coastal mills have shutdown. This has brought a lot of attention to log export policy. A common perception is that log exports are akin to exporting manufacturing jobs. Log exports increase harvesting activity by giving companies access to markets that are willing to pay more for logs than domestic manufacturers can afford. Without access to export markets many stands would not be harvested because the domestic log price is below the cost of harvesting them. The logs that are not exported, which was 76% in 2010, are sold domestically. Exports essentially subsidize domestic log prices and generate harvesting activity that would not have occurred otherwise. All sectors of the forest industry benefit from fewer log export restrictions.
The relationship between math achievement and functional connectivity in young adults with and without autism
Creators: name: Nkwo, Chinedu
Publisher: name: No Publisher Supplied
Year: 2024

description: Individuals with autism with average intelligence are often assumed to possess superior skills in the realm of mathematics, despite limited evidence supporting this claim. There is evidence, however, of under-connectivity in the brain as a feature of autism in adults that has been examined in resting-state functional connectivity research. This difference in connectivity is absent in neurotypical adults, underscoring the unique brain organization in ASD. The intraparietal sulcus (IPS) is a region involved in numerical processing and magnitude comparison, crucial skills for mathematical achievement. Studies examining IPS connectivity in neurotypical (NT) adults have found that greater IPS connectivity is related to higher math achievement. However, in children, greater connectivity is related to worse math achievement. No studies of IPS resting state connectivity and math achievement in autism have been conducted to date in adults. In this study, we examined the relationship between math achievement and IPS connectivity through analysis of cognitive performance and neural activity. Performance was measured through standardized metrics of general intelligence and academic ability. Resting-state data was collected by instructing participants to stare at a fixation cross while letting their minds wander. Cognitive results showed the NT group outperformed the ASD group in math fluency. Whole-brain analyses revealed greater IPS connectivity to parietal and occipital cortexes in NT compared to ASD. Covariate analysis revealed positive relations between math ability and neural activity in the NT group, while negative relations were found between math ability and neural activity in the ASD group. In examining both groups, functional connectivity of the ventromedial prefrontal cortex and left middle frontal gyrus were positively related to math ability in NT, but negatively related in the autism group. These results suggest that under-connectivity is a feature of greater math achievement in autism and that different brain organization may relate to strengths in math achievement in ASD. Future research studies should consider exploring measures in procedural math, as it relates to the detail-focused cognitive style in autism. The current study’s chosen measure of math ability combines conceptual and procedural math topics, obscuring individual effects on performance.

description: Context. Young Stellar Objects (YSOs) are observed to undergo powerful accretion events known as FU Orionis outbursts (FUors). Such events of episodic accretion are now considered to be common during low mass star formation, wherein the accretion onto the protostar occurs through a surrounding centrifugal disk. Increasing evidence suggests that the magnetic disk winds are crucial for driving disk accretion, as they carry both mass and momentum away from the disk. Aims. We aim to investigate the phenomenon of the ejection of magnetic disk winds during episodic accretion, with a focus on the dust contained within these winds. Methods. We conduct magnetohydrodynamic (MHD) simulations of formation and evolution of protoplanetary disk (PPD) in the thin-disk limit. We include evolution of dust with two populations and a realistic prescription for viscosity during outbursts, which depends on the local thermal ionization fraction. The disk evolves with the concurrent action of viscosity, self-gravity and magnetic disk winds. Results. The simulated disk displays outbursting behavior in the early stages, with the duration and frequency of the bursts, their rise times, and brightness amplitudes resembling the observations of FUors. We find that during the outbursts, the winds are over an order of magnitude more dusty, as compared to in quiescence. However, despite this increased dust content, the winds are still dust-depleted as the dust-to-gas ratio is about an order of magnitude lower than the canonical interstellar value of 0.01. The results of our numerical experiments are in general agreement with the available observational findings and they shed a light on the mechanism behind production of dusty winds during outbursting events in YSOs.

description: The Steiner Traveling Salesman Problem (STSP) is a variant of the classical Traveling Salesman Problem. The STSP involves incorporating steiner nodes, which are extra nodes not originally part of the required visit set but that can be added to the route to enhance the overall solution and minimize the total travel cost. Given the NP-hard nature of the STSP, we propose a quantum approach to address it. Specifically, we employ quantum annealing using D-Wave's hardware to explore its potential for solving this problem. To enhance computational feasibility, we develop a preprocessing method that effectively reduces the network size. Our experimental results demonstrate that this reduction technique significantly decreases the problem complexity, making the Quadratic Unconstrained Binary Optimization formulation, the standard input for quantum annealers, better suited for existing quantum hardware. Furthermore, the results highlight the potential of quantum annealing as a promising and innovative approach for solving the STSP.

description: Whether the Sun is an ordinary G-type star is still an open scientific question. Stellar surveys by Kepler and TESS, however, revealed that Sun-like stars tend to show much stronger flare activity than the Sun. This study aims to reassess observed flare and spot activity of Sun-like Kepler stars by fine-tuning the criteria for a more robust definition of Sun-like conditions and better comparability between the current Sun and Sun-like stars. We update one of the recent stellar Sun-like star samples by applying new empirical stellar relations between the starspot size and the effective stellar temperature to derive more reliable starspot group sizes. From the 265 solar-type stars, we could select 48 stars supporting the Kepler 30-minute cadence light curves. These were analyzed by implementing the gradient of the power spectra method to distinguish between spot- and faculae-dominated stars. We employed the $α$-factor to quantify the area ratio of bright and dark features on the stellar surface. We were able to group the 48 stars as being spot- or faculae-dominated, revealing a preferential distribution of the Kepler Sun-like stars towards the spot-dominated (44 stars) and transitional (four stars) regimes. As the current Sun is faculae-dominated, only the transitional stars were utilized for further evaluation. Additionally, accounting for comparability in stellar mass, radius, and rotation period, we show that only one of the utilized 265 Sun-like stars in the Kepler sample (i.e., KIC 11599385) allows for direct comparison to the current Sun. We further show that the single flare observed on KIC 11599385 falls right within the flare energy range estimated for the AD774/775 event observed in the cosmogenic radionuclide archives of $^{10}$Be, $^{14}$C, and $^{36}$Cl.

description: Wave-particle duality as one of the expression of Bohr complementarity is a significant concept in the field of quantum mechanics. Quantitative analysis of wave-particle duality aims to establish a complementary relation between the particle and wave properties. Beyond the conventional quantitative analysis depending on special choice of quantum information measures, we are aimed to provide a measure-independent complementary relation via coherence. By employing maximally coherent states in the set of all states with fixed diagonal elements, a measure-independent complementary relation is proposed. Based on this, we give a measure-independent description of wave-particle-mixedness triality in d-path interferometers. Our complementary relations reveal the relationship between wave-particle duality and quantum coherence, and also give a justification to coherence as it truly brings out the wave nature of quantum systems at its heart.

description: En los años cuarenta Buenos Aires tuvo un auge en la producción editorial local que interpeló a los nuevos públicos que se sumaron, gracias a las sostenidas políticas de escolarización. Más libros y público implicó que el espacio de intermediación fuera visibilizado en una publicación especializada para libreros y papeleros. En las líneas que siguen se propone analizar cómo se representó en Papel, Libro, Revista las relaciones entre las librerías, las editoriales y el público lector. La disputa por el tiempo de ocio se reavivaba frente a nuevos consumos culturales y se ubicó al libro como el principal perdedor. En una primera lectura de la revista se encontró que el crecimiento y creación de sellos editoriales trajo aparejado la urgencia por la especialización en la venta de libros. Los juguetes y los artículos de librería pronto perderían espacio en las vitrinas. La producción de catálogos con técnicas bibliotecológicas, los resúmenes y reseñas de libros para guiar la lectura del librero fueron algunas de las sugerencias que se hicieron para mejorar las ventas de las librerías que tenían que enfrentarse ante el cine, las radios y revistas para ganar el tiempo de ocio de los nuevos públicos que se sumaban al mercado del libro.

description: Cosmic rays (CR), both solar and Galactic, have an ionising effect on the Earth's atmosphere and are thought to be important for prebiotic molecule production. In particular, the $\rm{H_2}$-dominated atmosphere following an ocean-vaporising impact is considered favourable to prebiotic molecule formation. We model solar and Galactic CR transport through a post-impact early Earth atmosphere at 200Myr. We aim to identify the differences in the resulting ionisation rates, $ζ$, particularly at the Earth's surface during a period when the Sun was very active. We use a Monte Carlo model to describe CR transport through the early Earth atmosphere, giving the CR spectra as a function of altitude. We calculate $ζ$ and the ion-pair production rate, $Q$, as a function of altitude due to Galactic and solar CR. The Galactic and solar CR spectra are both affected by the Sun's rotation rate, $Ω$, because the solar wind velocity and magnetic field strength both depend on $Ω$ and influence CR transport. We consider a range of input spectra resulting from the range of possible $Ω$, from $3.5-15\, Ω_{\rm{\odot}}$. To account for the possibility that the Galactic CR spectrum outside the Solar System varies over Gyr timescales, we compare top-of-atmosphere $ζ$ resulting from two different scenarios. We also consider the suppression of the CR spectra by a planetary magnetic field. We find that $ζ$ and $Q$ due to CR are dominated by solar CR in the early Earth atmosphere for most cases. The corresponding $ζ$ at the early Earth's surface ranges from $5 \times 10^{-21}\rm{s^{-1}}$ for $Ω= 3.5\,Ω_{\rm{\odot}}$ to $1 \times 10^{-16}\rm{s^{-1}}$ for $Ω= 15\,Ω_{\rm{\odot}}$. Thus if the young Sun was a fast rotator, it is likely that solar CR had a significant effect on the chemistry at the Earth's surface at the time when life is likely to have formed.

description: The current commentary analyses the Nolan Report (2001) and the Annual Reports (2001-2007) of the Catholic Office for the Protection of Children and vulnerable Adults (COPCA) formed as a result of the Nolan Report (2001). The commentary determines how wilfully the Catholic Church of England and Wales responded to the Nolan recommendations. This paper explores the success of this first child-safeguarding model (2001 - 2007) in relation to the deficiencies and structural modifications suggested by the Cumberlege Commission (2007). In conclusion, the commentary identifies a range of shortcomings and difficulties in the establishment of a uniform and secure child protection mechanism within the Catholic Church of England and Wales.
Impacts of climate chanage on spruce beetles and mountain pine beetles : similarites, differences, and analysis of forest management techniques

description: Mountain pine beetle (Dendroctonus ponderosae) and spruce beetle (Dendroctonus rufipennis) are two primary bark beetles found in Western North America. Extraordinary outbreaks have occurred in both species populations which have resulted in significant forest mortality over the last two decades. Compared with historical eruptions, the recent outbreaks are considered to be a consequence of climate change. The rise in temperature, precipitation, and extreme weather events has affected the phenology of both insects and hosts. The two beetle species have been affected in diverse ways by climate change. The mountain pine beetle has been predominately affected by their range expansion through invasion into an increasing number of climatically suitable habitats, while the spruce beetle has been affected by an increase in the probability of the univoltine population within its host’s range. Regardless of these different mechanisms, climate change has resulted in a similar growth trend in the two species populations, thus leading to intensive biotic disturbances in north-western forests. Due to a conglomeration of uncertainties and challenges in forest management options, immediate direct or indirect intervention is required in the infested area to conserve valuable forest resources.

description: Il saggio, dopo aver analizzato i principali nodi interpretativi affrontati da dottrina e giurisprudenza a più di vent’anni dall’entrata in vigore del d.lgs. n. 231/2001 e a quindici dalla sua estensione alla materia prevenzionistica, si sofferma sulle prospettive di ulteriore impiego dei MOG. Il “modello 231” potrebbe difatti svolgere un ruolo ulteriore rispetto a quello cui è chiamato tradizionalmente, quindi non solo prevenire la responsabilità collettiva dell’ente rispetto ai reati di omicidio colposo e lesioni personali colpose, ma favorire la stessa limitazione della responsabilità personale del datore di lavoro e dei suoi ausiliari, mediante la migliore identificazione dell’obbligazione prevenzionistica che dal modello stesso immediatamente e mediatamente deriva.

description: Tree-based models are often robust to uninformative features and can accurately capture non-smooth, complex decision boundaries. Consequently, they often outperform neural network-based models on tabular datasets at a significantly lower computational cost. Nevertheless, the capability of traditional tree-based ensembles to express complex relationships efficiently is limited by using a single feature to make splits. To improve the efficiency and expressiveness of tree-based methods, we propose Random Oblique Fast Interpretable Greedy-Tree Sums (RO-FIGS). RO-FIGS builds on Fast Interpretable Greedy-Tree Sums, and extends it by learning trees with oblique or multivariate splits, where each split consists of a linear combination learnt from random subsets of features. This helps uncover interactions between features and improves performance. The proposed method is suitable for tabular datasets with both numerical and categorical features. We evaluate RO-FIGS on 22 real-world tabular datasets, demonstrating superior performance and much smaller models over other tree- and neural network-based methods. Additionally, we analyse their splits to reveal valuable insights into feature interactions, enriching the information learnt from SHAP summary plots, and thereby demonstrating the enhanced interpretability of RO-FIGS models. The proposed method is well-suited for applications, where balance between accuracy and interpretability is essential.
