Determinants of complicance with mandatory disclosure: research evidence

This study analyses research evidence on the determinants of compliance with mandatory disclosure requirements, classified in four main areas: business characteristics, country characteristics, enforcement and corporate governance. The literature concerning the compliance with mandatory disclosure requirements is a relatively recent field of research, when compared to the literature on voluntary disclosure. Given the well-known economic benefits of disclosure, it is of great interest to academics and practitioners to understand the incentives that explain the behaviour of firms in terms of compliance with disclosure requirements. This review provides several insights. First, although the business characteristics found in different studies as explanatory factors for the level of compliance are not always the same, there are four business characteristics that predominate as explanatory factors of the level of compliance with disclosure requirements: the firm’s size, the firm’s profitability, the type of auditor, and the level of internationalization. Second, the country characteristics and the enforcement have always proved to be relevant when analysing the level of compliance with mandatory disclosure requirements, independently of the approach used. Third, some corporate governance characteristics (including the nature of the board members and the type of ownership/control) begin to emerge as determinants of the level of compliance with mandatory disclosure. Overall, whereas research on the determinants of compliance with mandatory disclosure requirements provides relevant insights, it does not yet provide a sufficient accumulation of empirical evidence. Based on this, we develop suggestions for future research, highlighting the importance of analysing the role of corporate governance on the level of compliance with mandatory disclosure requirementsinfo:eu-repo/semantics/publishedVersio

Task interference effects in prospective memory

Prospective memory (PM), or remembering to remember, is biq it s i p pl ’s liv s a d PM misses might represent around half of daily memory failures according to recent research. In this thesis, several intention-related factors were investigated in order to clarify and elaborate our understanding of the effects of working memory (WM) and cognitive aging on prospective remembering, increase theoretical clarity regarding the dynamics of the monitoring processes in PM tasks, and investigate the interplay between two qualitatively different PM retrieval processes (i.e., spontaneous retrieval and monitoring). The overall approach was to examine how holding a particular intention affected ongoing task performance in a series of specifically devised laboratory studies of PM. The main findings of this thesis can be summarized as follows: First, encountering intention-related information boosted nonfocal PM performance for low, but not high, WM young adults, and did so without any additional cost to ongoing task performance (Experiment 1). Second, presenting intention-related information as distractor items improved PM performance for older, but not young adults (Experiments 2 and 3). The benefit was most likely due to distractor lures enhancing the salience of the target events and triggering spontaneous retrieval of the intention, or alternatively (or additionally), triggering (functional) monitoring in close proximity to the target events (Experiment 2). Third, practicing the ongoing activity prior to encoding the PM task enhanced nonfocal target detection for high WM young adults, but not for low WM young adults and older adults; practice probably allowed individuals to encode a more elaborate and detailed representation of the PM task (Experiment 4). Fourth, explicit information about target-defining features led to trial-by-trial modulations in task interference as a function of stimulus relevance for the nonfocal PM task. The effect was observed when relevant and irrelevant stimuli varied at random with no cuing (Experiments 5 and 6) and when presentation was blocked (Experiment 5), and was most likely associated with the action of top-down attentional control. Fifth, implicit information about the PM task demands also aff ct d pa ticipa ts’ ff t a d s cc ss i the PM task. Moreover, experience with the PM targets triggered local changes in attention allocation when actual demands were higher than expected (Experiment 7). And sixth, target repetition within a set boosted PM performance by stimulating retrieval through spontaneous retrieval processes, and optimized performance relative to when retrieval relied mostly on monitoring processes alone (Experiment 8). In summary, the present work uncovered several factors that have the potential to boost prospective remembering, as well as influence the extent to which monitoring processes are engaged and/or the type of processing required to support PM retrieval

Masonry behaviour and modelling

In this Chapter we present the basic experimental facts on masonry materials and introduce simple and refined models for masonry. The simple models are essentially macroscopic and based on the assumption that the material is incapable of sustaining tensile loads (No-Tension assumption). The refined models account for the microscopic structure of masonry, modeling the interaction between the blocks and the interfaces.(undefined

Relativistic Mean-Field Hadronic Models under Nuclear Matter Constraints

Relativistic mean-field (RMF) models have been widely used in the study of many hadronic frameworks because of several important aspects not always present in nonrelativistic models, such as intrinsic Lorentz covariance, automatic inclusion of spin, appropriate saturation mechanism for nuclear matter, causality and, therefore, no problems related to superluminal speed of sound. With the aim of identifying the models which best satisfy well known properties of nuclear matter, we have analyzed $263$ parameterizations of seven different types of RMF models under three different sets of constraints related to symmetric nuclear matter, pure neutron matter, symmetry energy, and its derivatives. One of these (SET1) is formed of the same constraints used in a recent work [M. Dutra et al., Phys. Rev. C 85, 035201 (2012)] in which we analyzed $240$ Skyrme parameterizations. The results pointed to $2$ models consistent with all constraints. By using another set of constraints, namely, SET2a, formed by the updated versions of the previous one, we found $4$ models approved simultaneously. Finally, in the third set, named SET2b, in which the values of the constraints are more restrictive, we found $3$ consistent models. Another interesting feature of our analysis is that the results change dramatically if we do not consider the constraint regarding the volume part of the isospin incompressibility ($K_{\tau,\rm v}$). In this case, we have $35$ approved models in SET2a and $30$ in SET2b.Comment: 63 pages, 3 figures and 9 tables. Version accepted for publication in PR

Final state interaction in D+→K−π+π+D^+\to K^-\pi^+\pi^+ with KπK\pi I=1/2 and 3/2 channels

The final state interaction contribution to $D^+$ decays is computed for the $K^-\pi^+\pi^+$ channel within a light-front relativistic three-body model for the final state interaction. The rescattering process between the kaon and two pions in the decay channel is considered. The off-shell decay amplitude is a solution of a four-dimensional Bethe-Salpeter equation, which is decomposed in a Faddeev form. The projection onto the light-front of the coupled set of integral equations is performed via a quasi-potential approach. The S-wave $K\pi$ interaction is introduced in the resonant isospin $1/2$ and the non-resonant isospin $3/2$ channels. The numerical solution of the light-front tridimensional inhomogeneous integral equations for the Faddeev components of the decay amplitude is performed perturbatively. The loop-expansion converges fast, and the three-loop contribution can be neglected in respect to the two-loop results for the practical application. The dependence on the model parameters in respect to the input amplitude at the partonic level is exploited and the phase found in the experimental analysis, is fitted with an appropriate choice of the real weights of the isospin components of the partonic amplitude. The data suggests a small mixture of total isospin $5/2$ to the dominant $3/2$ one. The modulus of the unsymmetrized decay amplitude, which presents a deep valley and a following increase for $K\pi$ masses above $1.5$ GeV, is fairly reproduced. This suggests the assignment of the quantum numbers $0^+$ to the isospin 1/2 $K^*(1630)$ resonance
