Children's Cognitive and Emotional Processes in Adult Versus Child-Related Inter-Parental Conflicts
In the literature, little attention has been paid to the specific impact of child-related versus adult-related inter-parental conflicts on children's intrapersonal processes and adjustment. Aimed to advance knowledge on this topic, the cross-sectional study explores: 1) the predictive effects of the two forms of inter-parental conflicts on: a) children's internalizing/externalizing behaviors and b) children's cognitive appraisals, emotional distress, and triangulation; 2) the mediating role of children's cognitive appraisals, emotional distress, and triangulation, in the association between adult-related vs child-related conflict and children's adjustment. Seventy-five school-aged children and their parents completed measures of inter-parental conflict, cognitive, emotional and behavioral processes and child adjustment. The results indicated that: 1) higher levels of adult-related inter-parental conflict promoted children's internalizing behaviors, through the mediation of perceived threat; 2) higher levels of child-related inter-parental discord promoted both children's internalizing/externalzing behaviors, through the mediation of perceived threat and self-blame
Paradox of temporal consciousness
Temporal consciousness seems so common that if we want to understand what philosophers find puzzling about it we must first look into the ways in which we would naively account for it. My initial worry will thus be that of making clear how puzzlement regarding temporal experience arises in the first place. In the first section, I will focus on a certain family of solutions, sometimes referred to as Specious Present theories, and analyse two main subsets of this family: extentionalism and retentionalism. In section two I will detect the point of contact between these views and formalise it in terms of the individuation argument, following Hoerl’s proposal. Then, I will advance some objections against this argument, leaving thus space, in the last section, to weigh up the validity of the solutions we met. This should allow us to better understand the conceptual knot that originated the puzzle, and contribute to individuate the space for a possible novel position. The aim of this work is to give a clear picture of the main solutions to the paradox of temporal consciousness and some of their deficiency, so to individuate the area where a possible new solution can be developed
Conformism, ignorance and injustice: AI as a tool of epistemic oppression
From music recommendation to assessment of asylum applications, machine-learning algorithms play a fundamental role in our lives. Naturally, the rise of AI implementation strategies has brought to public attention the ethical risks involved. However, the dominant anti-discrimination discourse, too often preoccupied with identifying particular instances of harmful AIs, has yet to bring clearly into focus the more structural roots of AI-based injustice. This paper addresses the problem of AI-based injustice from a distinctively epistemic angle. More precisely, I argue that the injustice generated by the implementation of AI machines in our societies is, in some paradigmatic cases, also a form of epistemic injustice. With a particular focus on AIs employed as gatekeepers of our epistemic resources, this paper shows how their epistemically conformist behaviour is responsible for the marginalisation and the ostracism of minoritarian perspectives. Because it clarifies key structural flaws and weaknesses of current AI design, this paper helps make headway in critical discussion of current AI technologies. And because it forges new theoretical tools to understand forms of epistemic oppression, this paper also contributes to the advancement of feminist theorisation

Cell Shortening and Calcium Homeostasis Analysis in Adult Cardiomyocytes via a New Software Tool
Intracellular calcium (Ca2+) is the central regulator of heart contractility. Indeed, it couples the electrical signal, which pervades the myocardium, with cardiomyocytes contraction. Moreover, alterations in calcium management are the main factors contributing to the mechanical and electrical dysfunction observed in failing hearts. So, simultaneous analysis of the contractile function and intracellular Ca2+ is indispensable to evaluate cardiomyocytes activity. Intracellular Ca2+ variations and fraction shortening are commonly studied with fluorescent Ca2+ indicator dyes associated with microscopy techniques. However, tracking and dealing with multiple files manually is time-consuming and error-prone and often requires expensive apparatus and software. Here, we announce a new, user-friendly image processing and analysis tool, based on ImageJ-Fiji/MATLAB® software, to evaluate the major cardiomyocyte functional parameters. We succeeded in analyzing fractional cell shortening, Ca2+ transient amplitude, and the kinematics/dynamics parameters of mouse isolated adult cardiomyocytes. The proposed method can be applied to evaluate changes in the Ca2+ cycle and contractile behavior in genetically or pharmacologically induced disease models, in drug screening and other common applications to assess mammalian cardiomyocyte functions
An Italian Study
The literature provides some evidence that the use of violent video games increases the risk for young people to develop aggressive cognitions and even behaviors. We aimed to verify whether exposure to violent video games is linked to problems of aggression in a sample of Italian children. Four questionnaires were administered to 346 children between 7 and 14 years of age, attending primary and secondary schools in Northern Italy. Variables measured were externalization, quality of interpersonal relationships, aggression, quality of coping strategies, and parental stress. Participants who preferred violent games showed higher scores for externalization and aggression. The use of violent video games and age were linked to higher levels of aggression, coping strategies, and the habitual video game weekly consumption of participants. Our data confirm the role of violent video games as risk factors for problems of aggressive behavior and of externalization in childhood and early adolescence
Gut microbiota composition and frailty in elderly patients with Chronic Kidney Disease
Background Frailty is common in older patients affected by chronic kidney disease (CKD). Since gut microbiota (gMB) may contribute to frailty, we explored possible associations between gMB and frailty in CKD. Methods We studied 64 CKD patients (stage 3b-4), categorized as frail (F, 38) and not frail (NF, 26) according to Fried criteria, and 15 controls (C), all older than 65 years. In CKD we assessed serum C-reactive protein, blood neutrophil/lymphocyte ratio, Malnutrition-inflammation Score (MIS); gMB was studied by denaturing gel gradient electrophoresis (DGGE), high-throughput sequencing (16S r-RNA gene), and quantitative real-time PCR (RT-PCR). Results No differences in alpha diversity between CKD and C and between F and NF patients emerged, but high-throughput sequencing showed significantly higher abundance of potentially noxious bacteria (Citrobacter, Coprobacillus, etc) and lower abundance of saccharolytic and butyrate-producing bacteria (Prevotella spp., Faecalibacterium prausnitzii, Roseburia spp.), in CKD respect to C. Mogibacteriaceae family and Oscillospira genus abundance was positively related to inflammatory indices in the whole CKD cohort, while that of Akkermansia, Ruminococcus and Eubacterium genera was negatively related. Compared with NF, in F there was a higher abundance of some bacteria (Mogibacteriacee, Coriobacteriacee, Eggerthella, etc), many of which have been described as more abundant in other diseases. Conclusions These results suggest that inflammation and frailty could be associated to gMB modifications in CKD
Is the Relationship Between Marital Adjustment and Parenting Stress Mediated or Moderated by Parenting Alliance?
The purpose of this study was to explore the mediating and moderating effects of parenting alliance on the relationship between marital adjustment, as represented by the dimensions dyadic consensus, dyadic satisfaction, dyadic cohesion, and affectional expression, and maternal and paternal stress. Self-report data were gathered from 236 Italian families (236 mothers:M= 40.9;SD= 4.4 and 236 fathers:M= 42.9;SD= 4.8) of children aged 6–11 years (M= 8.6;SD= 1.7). A set of regression analyses were conducted to examine whether parenting alliance mediates or moderates the relationship between marital adjustment and parenting stress. Regression analyses were consistent with a model of coparenting as a mediator but not as a moderator of the relationship between marital adjustment and parenting stress. In the case of mothers, parenting alliance mediates the relationships between two dimensions of marital adjustment (dyadic consensus and dyadic cohesion) on parenting stress; in the case of fathers, parenting alliance serves as a mediator of the relationship between the marital adjustment (in terms of dyadic satisfaction) and parenting stress. Implications for future research and interventions are discussed
Alginate Formulations: Current Developments in the Race for Hydrogel-Based Cardiac Regeneration
Cardiovascular diseases, including myocardial infarction (MI), represent the main worldwide cause of mortality and morbidity. In this scenario, to contrast the irreversible damages following MI, cardiac regeneration has emerged as a novel and promising solution for in situ cellular regeneration, preserving cell behavior and tissue cytoarchitecture. Among the huge variety of natural, synthetic, and hybrid compounds used for tissue regeneration, alginate emerged as a good candidate for cellular preservation and delivery, becoming one of the first biomaterial tested in pre-clinical research and clinical trials concerning cardiovascular diseases. Although promising results have been obtained, recellularization and revascularization of the infarcted area present still major limitations. Therefore, the demand is rising for alginate functionalization and its combination with molecules, factors, and drugs capable to boost the regenerative potential of the cardiac tissue. The focus of this review is to elucidate the promising properties of alginate and to highlight its benefits in clinical trials in relation to cardiac regeneration. The definition of hydrogels, the alginate characteristics, and recent biomedical applications are herewith described. Afterward, the review examines in depth the ongoing developments to refine the material relevance in cardiac recovery and regeneration after MI and presents current clinical trials based on alginate
