SOM neural network design – a new Simulink library based approach targeting FPGA implementation

The paper presents a method for FPGA implementation of Self-Organizing Map (SOM) artificial neural networks with on-chip learning algorithm. The method aims to build up a specific neural network using generic blocks designed in the MathWorks Simulink environment. The main characteristics of this original solution are: on-chip learning algorithm implementation, high reconfiguration capability and operation under real time constraints. An extended analysis has been carried out on the hardware resources used to implement the whole SOM network, as well as each individual component block

Interpreting IFRS: The Evolving Role of Agenda Decisions

This study examines the evolution of the interpretative support provided by the IFRS Interpretations Committee (IC), the interpretative body of the International Accounting Standards Board (IASB), over the period 2002–2019. The study focuses on its most frequent output, agenda decisions (ADs), which can provide guidance that practice has long considered relevant and has been explicitly considered authoritative since 2020. We investigate whether the IC has provided additional guidance and changed the formulation of ADs over time in response to constituents’ criticism from the perspective of legitimacy theory. We find that the IC has progressively added more explanatory material and formulated ADs in a more complete and nuanced manner so as to gain consequential legitimacy by substantially addressing the constituents’ interpretation demands. This evolution points to the growing role of ADs, which strike a balance between difficult to reconcile objectives. Providing more substantial support to constituents’ submissions can be seen as a balancing act between a more explicit shift from principles to rules, and leaving room for local interpretations that could threaten the consistent application of International Financial Reporting Standards (IFRS). In shedding light on the IC's substantial response to the challenges posed by conflicting pressures and objectives, we add to the standard-setting literature by providing evidence-based insights into under-researched areas of IFRS interpretation. We also respond to calls for more policy-oriented research and offer two proposals to enhance the clarity of ADs in the light of their evolving content and increasing relevance

Can “publishing game” pressures affect the research topic choice? A survey of European accounting researchers

This study explores the uninvestigated area of research agenda setting, which has considerable influence on the societal impact of accounting academia, which the paying-off mentality stemming from a "publish or perish" culture risks jeopardizing. More specifically, it investigates the research topic choice of accounting researchers to ascertain whether and how the "publishing game" pressures induced by the governance principles of new public management influence this crucial decision. Survey evidence shows that European accounting researchers choose their research topics by considering (i) explicit research requests, (ii) short-term publishing opportunities, (iii) practical and educational needs, and (iv) the intellectual needs of the academic community. In this respect, researchers seem to form a heterogeneous community that places varying importance on these factors, suggesting different effects of "publishing game" pressures. The three clusters aim at societal impact through diverse avenues, while the probability of rapid publishing seems to be the primary driver of another cluster, thus revealing a substantial risk of goal displacement. This study contributes to the debate on publishing pressures in accounting academia by complementing the contextualized reflections of previous literature with evidence documenting their effects on what (in addition to how) accounting researchers study. These findings have policy and practical implications that can help policymakers, university managers, gatekeepers of the publishing process, and our entire academic community

Feasibility studies of the time-like proton electromagnetic form factor measurements with PANDA at FAIR

The possibility of measuring the proton electromagnetic form factors in the time-like region at FAIR with the \PANDA detector is discussed. Detailed simulations on signal efficiency for the annihilation of $\bar p +p$ into a lepton pair as well as for the most important background channels have been performed. It is shown that precision measurements of the differential cross section of the reaction $\bar p +p \to e^++ e^-$ can be obtained in a wide angular and kinematical range. The individual determination of the moduli of the electric and magnetic proton form factors will be possible up to a value of momentum transfer squared of $q^2\simeq 14$ (GeV/c)$^2$. The total $\bar p +p\to e^++e^-$ cross section will be measured up to $q^2\simeq 28$ (GeV/c)$^2$. The results obtained from simulated events are compared to the existing data. Sensitivity to the two photons exchange mechanism is also investigated.Comment: 12 pages, 4 tables, 8 figures Revised, added details on simulations, 4 tables, 9 figure

Measuring the Effectiveness of National Enforcers in the IFRS Context: A Proactive Approach

It is widely acknowledged that an effective enforcement system represents a crucial element to achieve significant improvements in financial reporting through the adoption of high-quality accounting standards. Indeed, the quality of financial reporting is considerably influenced not only by the standards to be adopted but also by their actual implementation, and consequently by enforcement mechanisms.The topic has generated considerable interest among scholars, who devoted their attention to developing different measures of the quality of the enforcement system. Building upon this literature, this paper aims at exploring the accounting enforcement system and focuses on controls over financial reporting considering two levels, namely the auditing activity and the controls performed by national enforcers.This paper extends the prior literature by proposing a dynamic measure of the accounting enforcement system capturing controls at those two levels. More specifically, the index here proposed focuses on the quality of the accounting enforcement operated by national enforcers in terms of proactivity, intended as the national enforcers’ capability to detect problems not highlighted in the auditors’ opinions, thus shifting the focus from an input to an output perspective. Indeed, the activities of auditors and national enforcers are strictly connected, given that the auditors’ opinion is the first public output of accounting controls and that is normally one of the bases for further investigation by national enforcers. An illustrative empirical analysis is carried out on the German and the Italian contexts to show the potential of the index for enforcement studies.</jats:p

Il trattamento della cheilognatopalatoschisi nei pazienti in adozione: valutazione di 56 casi nel Percorso Labiopalatoschisi di Pisa

Il trattamento della cheilognatopalatoschisi nei pazienti adottati è una tematica che si sta rivelando sempre più frequente a causa dell'aumento delle adozioni di bambini "special needs", così definiti a causa della presenza di patologie al momento dell'iter adottivo. Il nostro elaborato si prefigge di analizzare quali e quante difficoltà vengono riscontrate dal punto di vista chirurgico (sia su operazioni primarie che in operazioni secondarie a seguito di precedenti interventi effettuati altrove e con esiti non soddisfacenti) e quali complicanze affliggono questi pazienti che, per varie motivazioni, hanno un età superiore rispetto a quella dei bambini che affrontano l'iter terapeutico di trattamento della labiopalatoschisi secondo i protocolli universalmente codificati, e nello specifico secondo il protocollo pisano

Feasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR

Simulation results for future measurements of electromagnetic proton form factors at \PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel $\bar p p \to e^+ e^-$ is studied on the basis of two different but consistent procedures. The suppression of the main background channel, $\textit{i.e.}$ $\bar p p \to \pi^+ \pi^-$, is studied. Furthermore, the background versus signal efficiency, statistical and systematical uncertainties on the extracted proton form factors are evaluated using two different procedures. The results are consistent with those of a previous simulation study using an older, simplified framework. However, a slightly better precision is achieved in the PandaRoot study in a large range of momentum transfer, assuming the nominal beam conditions and detector performance
