  1. Describing the Macroscopic World: Closing the Circle Within the Dynamical Reduction Program. [REVIEW]G. C. Ghirardi, R. Grassi & F. Benatti - 1995 - Foundations of Physics 25 (1):5-38.
    With reference to recently proposed theoretical models accounting for reduction in terms of a unified dynamics governing all physical processes, we analyze the problem of working out a worldview accommodating our knowledge about natural phenomena. We stress the relevant conceptual differences between the considered models and standard quantum mechanics. In spite of the fact that both theories describe systems within a genuine Hilbert space framework, the peculiar features of the spontaneous reduction models limit drastically the states which are dynamically stable.

    Relativistic Dynamical Reduction Models: General Framework and Examples. [REVIEW]G. C. Ghirardi, R. Grassi & P. Pearle - 1990 - Foundations of Physics 20 (11):1271-1316.
    The formulation of a relativistic theory of state-vector reduction is proposed and analyzed, and its conceptual consequences are elucidated. In particular, a detailed discussion of stochastic invariance and of local and nonlocal aspects at the level of individual systems is presented.

    Outcome Predictions and Property Attribution: The EPR Argument Reconsidered.GianCarlo Ghirardi & Renata Grassi - 1994 - Studies in History and Philosophy of Science Part A 25 (3):397-423.
    We reconsider the nonlocal aspects of quantum mechanics with special reference to the EPR argument. We first confine our considerations to the correlations between the outcomes of measurements on spatially distant constituents, without worrying about the measurement problem. We pay particular attention to the relativistic aspects of the problem. Our first conclusion is that, when developed along the lines we follow, the EPR inference that quantum correlations and locality together imply incompleteness, is appropriate. We then investigate whether the other common (...)

    Parameter Dependence and Outcome Dependence in Dynamical Models for State Vector Reduction.G. C. Ghirardi, R. Grassi, J. Butterfield & G. N. Fleming - 1993 - Foundations of Physics 23 (3):341-364.
    We apply the distinction between parameter independence and outcome independence to the linear and nonlinear models of a recent nonrelativistic theory of continuous state vector reduction. We show that in the nonlinear model there is a set of realizations of the stochastic process that drives the state vector reduction for which parameter independence is violated for parallel spin components in the EPR-Bohm setup. Such a set has an appreciable probability of occurrence (≈ 1/2). On the other hand, the linear model (...)

    O Pluralismo da Verdade.Rita Macedo Grassi - 2020 - Horizonte 18 (55):395.
    Este texto foi publicado na revista World Faith Insights 26, 1990, p. 7-16 e é a transcrição de uma palestra proferida pelo teólogo e filósofo catalão Raimon Panikkar. Por se tratar de uma transcrição fiel da linguagem oral, nosso desafio nesta tradução foi adequar o texto à linguagem escrita sem, no entanto, perder os traços característicos do palestrante e autor.

    Mood Disorder in Cancer Patients Undergoing Radiotherapy During the COVID-19 Outbreak.Valerio Nardone, Alfonso Reginelli, Claudia Vinciguerra, Pierpaolo Correale, Maria Grazia Calvanese, Sara Falivene, Angelo Sangiovanni, Roberta Grassi, Angela Di Biase, Maria Angela Polifrone, Michele Caraglia, Salvatore Cappabianca & Cesare Guida - 2021 - Frontiers in Psychology 12.
    Introduction: Novel coronavirus is having a devastating psychological impact on patients, especially patients with cancer. This work aims to evaluate mood disorders of cancer patients undergoing radiation therapy during COVID-19 in comparison with cancer patients who underwent radiation therapy in 2019.Materials and Methods: We included all the patients undergoing radiation therapy at our department in two-time points and during the COVID-19 outbreak. All the patients were asked to fulfill a validated questionnaire, the Symptom Distress thermometer, and the Beck Depression Inventory (...)
