Ammissibilità della prova e divieti probatori
Authors: Ferrua Paolo 
Published: March 2021

Prova ‘ammissibile’ è tutto ciò che può essere legittimamente valutato in ordine a una proposizione da provare. Prova ‘inammissibile’ è quella che il giudice non ha il potere di assumere e, come tale, appartiene alla sfera del giuridicamente irrilevante. Occorre tenere ben distinte le questioni relative all’ammissibilità della prova da quelle relative all’efficacia probatoria, ossia alla persuasività. Analogamente non va confusa la prova come premessa probatoria, che esprime una mera potenzialità (la prova su x) con la prova come risultato (la prova di x), che indica un esito positivo. Con riguardo alle premesse probatorie, resta fondamentale la controversa distinzione tra prove dichiarative e prove critico-indiziarie. Parlando di prove «acquisite in violazione dei divieti stabiliti dalla legge», l’art. 192 c.p.p. è stato variamente interpretato: secondo alcuni, va riferito alle sole prove oggetto di un divieto probatorio, ossia inammissibili; secondo altri, anche alle prove ‘ottenute’ attraverso una qualsiasi violazione della legge (penale processuale o sostanziale o persino civile). Di recente è stata sollevata una questione di legittimità sul presupposto che le prove assunte in spregio dei diritti costituzionalmente tutelati non possano essere utilizzate, anche in assenza di un esplicito divieto probatorio. La Corte costituzionale ha, tuttavia, dichiarato inammissibile la questione con argomenti poco convincenti. Si è così persa la preziosa occasione per il definitivo chiarimento di un fondamentale interrogativo.

Integrated Business Intelligence and Analytics: The Case of the Department of the Navy
Authors: Eger Robert J. , Smith Christy 
Published: March 2021

ABSTRACT
From a stakeholder perspective, this study explores the viability of data analytics as a tool in government fraud prevention. Using an interview methodology, we analyze the implications of business intelligence and analytics fraud tools on procurement stakeholders. We find that implementing and integrating business intelligence and a fraud program streamlines processes by consolidating information and presenting data within a unique program. The functioning data analytics program increases our stakeholders' confidence level without alleviating their responsibility to perform due diligence in their management functions. Our stakeholders recognized a potential increase in workload; however, they acknowledged no perceived increase in undue administrative burden.

The Effect of Auditor Reporting Choice and Audit Committee Oversight on Management Financial Disclosures
Authors: Fuller Stephen H. , Joe Jennifer R. , Luippold Benjamin L. 
Published: March 2021

ABSTRACT
We investigate the joint effects of auditors' reporting choice and audit committee effectiveness on management disclosures about complex estimates. A new PCAOB standard requires auditors to report on Critical Audit Matters (CAMs): issues “communicated or required to be communicated to the audit committee” about accounts or disclosures that (1) “are material to the financial statements,” and (2) “involved especially challenging, subjective, or complex auditor judgment” (PCAOB 2017a, 11). Consistent with investor arguments, we find that audit committee effectiveness and more detailed CAM reporting encourage managers' disclosures of the risk underlying complex estimates. When the auditor's report is more informative about a complex estimate and the audit committee is more effective, management's related financial disclosures are more forthcoming. However, less informative auditor disclosures or more effective audit committees alone do not prompt greater management disclosure. Thus, expanded auditor reporting and more effective audit committees, together, can enhance the disclosures investors value.
The Effect of Mandatory Disclosure on Market Inefficiencies: Evidence from FASB Statement No. 161
Authors: Campbell John L. , Khan Urooj , Pierce Spencer 
Published: March 2021

ABSTRACT
Prior research finds that unrealized gains/losses on cash flow hedges are negatively associated with future earnings, and that investors and analysts fail to anticipate this association. These studies speculate that this mispricing is due to either poor derivatives disclosures or the accounting model for cash flow hedges. We examine whether enhanced mandatory derivatives disclosures set forth in FAS 161 improve users' understanding of firms' hedging activities and offer three main findings. First, we find that this mispricing does not persist after FAS 161. Second, we find that the correction of mispricing is greatest when disclosure might help investors most. Finally, we find that analyst forecast accuracy improves after FAS 161. Overall, our results suggest that the enhanced mandatory derivative disclosures required by FAS 161 improved users' understanding of the effects of derivative and hedging activities on future firm performance and firm value—and consequently mitigated investor mispricing.
CEO Tenure and Firm Value
Authors: Brochet Francois , Limbach Peter , Schmid Markus , Scholz-Daneshgari Meik 
Published: March 2021

ABSTRACT
Our study is the first to provide systematic evidence of a hump-shaped CEO tenure-firm value relation. Cross-sectionally, firm value starts to decline after fewer years of CEO tenure in more dynamic industries, if CEOs are less adaptable to changes, and in the presence of greater labor market frictions. Overall, the dynamics of CEO-firm match quality appear to be a first-order driver of the CEO tenure-firm value association, as explained by CEO characteristics (adaptability), firm/industry characteristics (dynamism), and labor market characteristics that facilitate optimal matching between firms and CEOs.

The quality of etched enamel in different regions and tooth types and its significance in bonding and the development of white spot lesions
Authors: Barnhart Elisabeth C. , Campbell Phillip M. , Noureldin Amal , Julien Katie , Buschang Peter H. 
Published: March 2021

ABSTRACT

Objectives
To quantify differences in the etch quality of enamel within and between human teeth, which has not previously been attempted.

Materials and Methods
The buccal right and left halves of 27 extracted human teeth were randomly allocated to scanning electron microscopy (SEM) or micro–computed tomography (μCT) for evaluation. The buccal surfaces were pumiced, etched with 37% phosphoric acid gel etchant for 15 seconds, rinsed, and air dried. Each tooth was divided into three regions (incisal, middle, and cervical) and viewed after etching at 1200× magnification with SEM. The μCT scans were taken before and after etching to calculate apparent and material mineral densities.

Results
SEM showed greater aprismatic enamel and poorer etch quality (ie, significantly less percentage enamel) for the posterior than anterior teeth and for the cervical region than for the incisal and middle regions of all teeth. Although there were no density differences prior to etching, μCT demonstrated that etching increased material density significantly more for the anterior than posterior teeth. Prior to etching, the enamel in the cervical regions was significantly less dense than the enamel in the middle or incisal regions. Etching significantly increased the material density of all three regions, which decreased initial regional differences. After etching, the apparent density of the cervical region remained significantly lower than the densities of the other two regions.

Conclusions
Based on SEM and μCT, there is greater aprismatic enamel and inferior etch quality in the cervical regions of all tooth types and is clinically significant in explaining the failure of sealant retention and the propensity for white spot lesions.

Tonalite-trondjemite-granodiorite formation of the Archaean. Special features of composition and conditions of formation, Ukrainian Shield as an example
Authors: Usenko O.V. 
Published: March 2021

Tonalite-trondjemite-granodiorite formation (TTG) produces the main volume of acidic rocks of the continental crust. Similar rocks are never met later. Therefore the problems of their production are directly connected with the problem of the crust and mantle formation.
The structure of the Archean TTG formation of granite-gneiss area of the Bug megablock and granite-grrenstone area of the Middle Dnieper megablock (MDMB) has been considered. Similar and different features have been found. The analysis of these data resulted in a conclusion that within the MDMB, West Periazovian and Khashchevate-Zavalie block of the Middle Bug area the events of formation of the Archean granite-greenstone area were similar, however these three blocks of the Ukrainian Shield demonstrate different levels of erosion damage reflected in PT-conditions of metamorphic transformations.
The rocks of TTG formation are a part of complex structured stratum appeared as a result of impregnation (migmatization) by quartz-albite melt of the primary crust and/or of more ancient strata of predominantly basic composition. In the middle-lower crust a partial replacement of the primary crust occurred and in the upper one — the deposition of new portions of the melt on the earlier ones, piercement of granite masses and migmatization of volcanogenic stratum. During the Archean these events happened repeatedly, that resulted in partial replacement of the primary crust with plagiogranites.
Modern notions have been considered on the processes of producing of TTG granite formation. It has been shown that according to thermal model distribution of temperatures in the crust does not cross the line of basalt water solidus. That is why the appearance of granite melts could not be the result of submergence to big depths (ultrametamorphism). Chronological and genetic relation with mantle melting, of which komatiites and spilites of green-stone structures were crystallized, assumed convective flows in the mantle. To explain the formation of tonalite and trondjemite melt a model of two-leveled crystallization differentiation of ultrabasic melt has been used. However appearance of primary basalt replacement in such a scale and assimilation of green-stone roots by granite melt are possible only in case of interaction of mantle fluids with the rocks of primary crust. An assumption has been made that the composition of some part of these fluids could be close to composition of granite (trondjemite). According to the author’s opinion such assumption confirms a hypothesis of V. Griffin and N. Pirson about formation of crystalline mantle on the border between the Archean and Proterozoic.
The theoretical-empirical technique of hydrocarbons prediction in wells sections. New aspects
Authors: Skakalska L. , Nazarevych A. , Kosarchyn V. 
Published: March 2021

We present the developed theoretical-empirical technique for predicting of rocks’ oil-and-gas bearing in wells sections according to acoustic logging (AL) and core research (CR) and its variants by using data of other loggings and also the results of testing them on wells sections data in the Western oil and gas bearing region of Ukraine (WOGR). The mathematical apparatus of the created technique is based on a mathematical model of solid porous rock, empirical relationships between elastic and reservoir characteristics of rocks and acoustic logging data for specific studied wells. The key parameter in the calculations is the rock compressibility. Determination of the porosity of rocks and prediction of the type of pore filler (water, oil, gas) is implemented by comparing the results of calculating the velocities using theoretical and constructed empirical relationships with the actual data of the AL, by the parameter of compressibility of rocks, by the density of the pore filler fluid.
Additional versions of the technique have been developed based on correlation dependences and data from other logging methods — gamma-ray logging (GL), electric logging (EL/SP), offset method and seismic logging (SL). They are used in case of absence of AL data for the studied wells or for the intervals of their sections, and also for improving the reliability of prediction the oil and gas content of these sections. The software for the implementation of the technique was developed in Fortran, C# and Excel software environments.
The technique was tested on the data of wells of a number of structures of the WOGR of Ukraine (Lishchyns’ka, Buchats’ka, Ludyns’ka, Zaluzhans’ka, Zarichnyans’ka and Nyklovyts’ka).The technique ensures reliable prediction of petrophysical characteristics, porosity and oil-gas-water saturation of rock layers of different thicknesses (including thin layers — from 0.1—0.2 m) in well sections. For this, in addition to the data of the general parametric base of the WOGR reservoir rocks, the specially constructed refined empirical relations for various specific types and subtypes of the WOGR reservoir rocks are used, they are based on the results of analysis of petrophysical characteristics of those rocks.
La reinvención del arte (underground)
Authors: Maillo Palma Laura 
Published: March 2021

Estamos atravesando un momento de reinvención del arte debido a unas circunstancias sociales sin precedentes, dada la magnitud de las consecuencias derivadas de la pandemia del Covid-19 en nuestro planeta globalizado. Para contestar a la pregunta de cómo hacer frente a esta urgencia de cambio, pensaremos en la figura del artista contemporáneo underground apoyándonos en el concepto de «artista radicante» de Nicolas Bourriaud, y en la práctica artística, en tanto que abierta a la continua transformación y renovación. Postularemos que la identidad del artista se produce mediante actos performativos, tal y como se construye la identidad de género según la teoría queer. Por tanto, la reinvención del arte pasa por una reinvención de la identidad artística. Por último, plantearemos la dificultad que supone para las artes (especialmente aquellas para las que es más importante la copresencia física) la restricción con respecto a compartir espacios físicos públicos. ¿Cómo extrapolar la producción y recepción artísticas a los espacios virtuales? Concluiremos apostando por el aprovechamiento de este momento de reinvención para crear nuevos tejidos para la comunidad artística apoyándonos en las herramientas digitales. Nuestro marco de pensamiento está definido por autores como Bourriaud, Judith Butler, Michel Foucault, Byung-Chul Han, Larry Shiner y Luis Racionero.

Research objectivesdata analysis of the radiological methods different types of dysregenerations, based on the clinical cases.Material and methods. Literature review about radiation semiotics regeneration and dysregeneration phenomena, applicability of different types of radiological methods has been done. A review of 2 cases of delayed union and 5 cases of fracture nonunion is presented.Conclusion. Despite the improvement and technical simplicity of visualizing the phenomena of dysregeneration, it is difficult to differentiate delayed union from nonunion using only by radiological methods, respectively, a consensus of an orthopedic surgeon and a radiologist is required in each individual case. The clinician chooses the treatment tactics based on the complex data set, including radiological methods.
