The interplay between ethics and aesthetics in intelligent systems-users interaction

In this paper, I address the interplay between ethics and aesthetics, in the context of everyday interaction with smart systems. This study is the result of a year’s time development of my PhD research, whose general aim is to understand how people’s beliefs and behaviours come to be shaped by the aesthetic experience with smart things. The expected outcome is a set of design strategies to integrate moral reasoning in the framework of design for behaviour change, relying on aesthetics in interaction. Preliminary results are presented, based on a literature review in the area of aesthetics of interaction. Although basic, these findings are helpful for they suggest that ethics and aesthetics in users-smart systems interaction are interdependent. This insight holds promise for the development of an aesthetics of moral reasoning, in the context of users-smart systems interaction. A researchthrough- design approach will be adopted in the remaining two years, with the aim of testing assumptions by means of working prototypes

Consensus definitions of 14 severe acute toxic effects for childhood lymphoblastic leukaemia treatment: a Delphi consensus

Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment

Can Machine Learning Models Predict Asparaginase-associated Pancreatitis in Childhood Acute Lymphoblastic Leukemia

Publisher Copyright: © 2021 Lippincott Williams and Wilkins. All rights reserved.Asparaginase-associated pancreatitis (AAP) frequently affects children treated for acute lymphoblastic leukemia (ALL) causing severe acute and persisting complications. Known risk factors such as asparaginase dosing, older age and single nucleotide polymorphisms (SNPs) have insufficient odds ratios to allow personalized asparaginase therapy. In this study, we explored machine learning strategies for prediction of individual AAP risk. We integrated information on age, sex, and SNPs based on Illumina Omni2.5exome-8 arrays of patients with childhood ALL (N=1564, 244 with AAP aged 1.0 to 17.9 y) from 10 international ALL consortia into machine learning models including regression, random forest, AdaBoost and artificial neural networks. A model with only age and sex had area under the receiver operating characteristic curve (ROC-AUC) of 0.62. Inclusion of 6 pancreatitis candidate gene SNPs or 4 validated pancreatitis SNPs boosted ROC-AUC somewhat (0.67) while 30 SNPs, identified through our AAP genome-wide association study cohort, boosted performance (0.80). Most predictive features included rs10273639 (PRSS1-PRSS2), rs10436957 (CTRC), rs13228878 (PRSS1/PRSS2), rs1505495 (GALNTL6), rs4655107 (EPHB2) and age (1 to 7 y). Second AAP following asparaginase re-exposure was predicted with ROC-AUC: 0.65. The machine learning models assist individual-level risk assessment of AAP for future prevention trials, and may legitimize asparaginase re-exposure when AAP risk is predicted to be low.Peer reviewe

Developing a data classification framework

This book provides a theoretical framework for design researchers interested in developing their research work about and with prototypes. It describes prototypes' multiple definitions and possible functions in the multifaceted landscape of today's design research. Indeed, while the manufacturing and digital evolutions enable and require new types of advanced prototypes, the design evolution as an academic discipline continuously widens its perspectives, fields, and research methods, among which are the prototypes' applications, features, and purposes. The framework originates from an interpretation of these interrelated phenomena and a collection of case studies. Additionally, it defines those criteria that characterize the relation between the research (context, discipline, and general scope) and the prototype (nature and specific aims) and, altogether, it presents an overview of prototypes' roles in design research

Changing Prospects in Design Education. Rupture and Ties with the Legacy of the Ulm Model

Focusing on Maldonado’s role as an educator, what surprises is the depth of thought that characterises his writings as well as his theoretical competence. Trained as an artist, Maldonado was exceptionally cultivated, endowed with great critical attitude, and passionate for design, not merely as a practice, but as a form of education. To this type of education, since the 1950s, he dedicated a large part of his career and academic endeavours, working on the development of a philosophy of design. The weight that Maldonado’s work carries within the history of design education is exemplified by the prestige of what is known as Ulm Model, a benchmark for most schools of design still today. Understanding the legacy of the Ulm School of Design (Ulm HfG) – whose training approach owes much to Maldonado – in the contemporary landscape of design education became the starting point of our investigation. A critical reading of some of Maldonado’s writings on the theory of education helped us trace the connections between the traditional models and the current reform of education in the field of design. In this respect, the end point was the conflicted relationship that the current reform movement shows to have with the old paradigm of design education. While breaking with the past, most of the schools that are leading the change prove to be rooted in the pedagogical tradition of the Ulm HfG. Shedding light on this ambivalence is the aim of our research. In addition to examining the nature of the ambivalent relationship that some world leading schools of design have with the traditional models of education, this essay gives an overview of how design education as a whole is evolving and what possible course(s) it may take in the near future

Prevalencia de anticuerpos anti-toxoplasma en pacientes con enfermedades autoinmunes

The identification of etiological factors in the induction of autoimmunity has remained elusive despite an enormous effort at dissection of the molecular structure of the target antigens and effector mechanisms. One characteristic feature of autoantigens is their repetitive structure as well as their conservation and evolution. Toxoplasma (T.) gondii is a primitive protozoan. We hypothesized that patients with autoimmune disease would have broad reactions against Toxoplasma antigens based on autoantigen conservation. To address this issue, we assessed serologic evidence of reactivity to Toxoplasma gondii along with a large profile of autoantibodies in patients with various autoimmune diseases (AID). We included sera of 1514 patients with 11 different AID collected from referral centers in Europe and Latin America as well as from 437 geographically matched controls, for the prevalence of anti Toxoplasma antibodies (ATxA) IgG and IgM and serum autoantibodies utilizing the BioPlex 2200 system (Bio- Rad Laboratories, USA). Serum ATxA IgG were positive in 42% of patients with AID versus 29% of controls (p < 0.0001). Among Europeans, ATxA IgG were associated with anti-phospholipid syndrome (APS; p < 0.0001), cryoglobulinemia (p < 0.0001), ANCA-associated vasculitides (p < 0.01), autoimmune thyroid diseases (p < 0.0001), systemic sclerosis (SSc; p < 0.0001) and rheumatoid arthritis (RA; p < 0.0001). Of note, Latin American RA sera exhibited similar frequency of ATxA IgG as controls. ATxA IgM were more prevalent in European patients with APS (p < 0.01), SSc (p < 0.05) and inflammatory bowel disease (IBD, p < 0.05) than in controls. Further, in AID patients the presence of ATxA correlated with autoantibodies characteristic of APS (anti- cardiolipin, B2GPI, complex of cardiolipin- B2GPI, prothrombin, phosphatydilethanolamine), and of SSc (anti-centromere, Scl-70). Our findings suggest that T. gondii may contribute to the pathogenesis of AID. This interaction may depend on or explain observed geoepidemiological variance in AID

Prevalence of hepatitis C serum antibody in autoimmune diseases

Objective: To evaluate the prevalence of serum antibodies against hepatitis C virus and other infectious agents in a large cohort of well-characterized patients with autoimmune diseases (AID). Methods: We utilized 1322 sera from patients with 18 different AID and 236 sera from healthy controls from the same countries and with similar age and sex distribution. All sera were tested for the presence of serum anti-hepatitis C virus (HCV) antibodies as well as antibodies directed at other infectious agents and autoantibodies. Results: Anti-HCV antibody was detected in 115/1322 (8.7%) of patients with AID and 0.4% of matched healthy controls (P less than 0.0001). The prevalence of anti-HCV antibody was significantly higher in 7/18 different AID (i.e. cryoglobulinemia, mixed cryoglobulinemia pemphigus vulgaris, vasculitis, secondary anti-phospholipid syndrome, Hashimoto's thyroiditis, and inflammatory bowel disease) compared to controls. Patients with AID and serum anti-HCV positivity had an increased prevalence of antibodies against hepatitis B virus, Toxoplasma gondii and Cytomegalovirus as opposed to a lower frequency of serum autoantibodies. Conclusions: The enhanced prevalence of anti-HCV serum antibodies in AID may suggest a role for HCV in tolerance to breakdown, similarly to its established role in mixed cryoglobulinemia. This immune mediated effect does not rule out the role of other infectious agents. © 2009
