A novel heuristic algorithm for the modeling and risk assessment of the COVID-19 pandemic phenomenon

2020

This article belongs to the special issue: Soft computing techniques in materials science and engineering Summarization: The modeling and risk assessment of a pandemic phenomenon such as COVID-19 is an important and complicated issue in epidemiology, and such an attempt is of great interest for public health decision-making. To this end, in the present study, based on a recent heuristic algorithm proposed by the authors, the time evolution of COVID-19 is investigated for six different countries/states, namely New York, California, USA, Iran, Sweden and UK. The number of COVID-19-related deaths is used to develop the proposed heuristic model as it is believed that the predicted number of dai…

Time trends, sociodemographic and health factors associated with discharge and length of stay of hospitalised patients with sickle cell disease in Gh…

2021

ObjectivePatients with sickle cell disease (SCD) are prone to multiple episodes resulting in frequent hospital visits. We determined the time trends, sociodemographic and health factors associated with length of stay (LoS) for patients with SCD in Ghana.Design, participants, settingWe retrospectively analysed SCD hospitalisation records of 22 680 patients from a nationwide database of the Ghana Health Service from 2012 to 2017.Outcome measuresFactors associated with LoS were estimated using Cox regression, while the cumulative incidence of being discharged alive was estimated with in-hospital death as a competing risk.ResultsPatients admitted for SCD over 6 years constituted 22 680 (0.8%) o…

Loneliness, subjective health complaints, and medicine use among Finnish adolescents 2006-2018.

2022

Aims: Loneliness is an important public health challenge for all ages. This study reports time trends of loneliness among adolescents over a 12-year period and analyses the strength of the associations between loneliness, health complaints, and medicine use. Methods: Data were derived from the cross-sectional Finnish Health Behaviour in School-aged Children study conducted in 2006, 2010, 2014, and 2018. The study population is based on a random sample of schools with 20,444 participants aged 11–15 years. The trends were analysed with a Mantel–Haenszel test, and the strength of the associations was evaluated by mixed-effects logistic and linear regressions. Results: An increasing prevalence …

The role of mothers' beliefs in students' self-concept of ability development

2018

The aim of this study was to investigate whether the child-related competence beliefs of mothers are associated with the development of Finnish adolescents' self-concept of mathematics and literacy ability during their transition from primary to lower secondary school and whether these associations depend on adolescents' level of performance. The results showed that, first, adolescents' self-concept of mathematics and literacy ability decreased over time. The impact of maternal beliefs on the linear trend of the self-concept of mathematics and literacy ability was dependent on the level of students' performance. Mothers' high beliefs buffered against the decrease in adolescents' self-concep…

Riflessioni su pandemia e comunicazione politica: l’interesse online per leader e partiti

2021

Has the pandemic reversed trends already taking place in contemporary politics or has it reinforced ongoing political phenomena? The serious health risk posed by the spread of Covid-19 has in fact legitimised dynamics that more or less silently had long been spreading, including the personalisation of politics, the (alleged) disintermediation of communication, different populist styles, the danger of authoritarian drifts. The challenges to democracy identified by the political literature, as the pandemic spreads, are enriched by new elements. Trust in national institutions, which has been years marked by a negative trend, in countertendency has increased during the peak of the epidemic. new…

Positioning Strategies of Cultural Institutions: A Renewal of the Offer in the Face of Shifting Consumer Trends

2008

Positioning strategies of cultural institutions : a renewal of the offer in the face of shifting consumer habits

2008

One conclusion is widely shared by the practitioners in the cultural sector: consumer relations with cultural products and services have changed. This paper provides a trend marketing analysis of various areas (theatres and performing arts organizations, museums, cultural events, cultural industries, etc.) so as to better understand this “new” cultural consumer. Seven contemporary trends are examined. Each is defined and then illustrated by innovative offers from cultural organizations. Their appraisal by more than a hundred cultural-sector practitioners in France is presented.

Worldwide trends in blood pressure from 1975 to 2015: a pooled analysis of 1479 population-based measurement studies with 19.1 million participants

2017

Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. Methods For this analysis, we pooled national, subnational, or community population-based studies that had measured blood pressure in adults aged 18 years and older. We used a Bayesian hierarchical model to estimate trends from 1975 to 2015 in mean systolic and mean diastolic blood pressure, and the prevalence of rai…

Long effective evapotranspiration (E) series was derived from the longest temperature series available in Sicily. The regional trend analysis performed has shown a slight upward trend of E.

Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV

2021

Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
