Strings of Adulthood: A Sequence Analysis of Young British Women’s Work-Family Trajectories
Employment, union formation and childbearing are central processes within young individuals’ transition to adulthood. These processes interact in highly complex ways, and they shape actual
Faster Route to the CEO Suite
The aim of this article is to investigate the differences between the careers of CEOs in family and nonfamily firms and the differences between the careers of family and nonfamily CEOs within family
Probability of symptoms and critical disease after SARS-CoV-2 infection
Contacts of SARS-CoV-2 index cases detected in Lombardy, Italy were analyzed, and positive subjects were ascertained via nasal swabs and serological assays and the risk of symptoms increased with age, with males at significantly higher risk.
Analyzing Demographic Life Courses through Sequence Analysis
Optimal matching and a monothetic divisive algorithm for the clustering of sequences of life courses are shown to be useful tools for the sequence analysis of the transition to adulthood from the Italian Fertility and Family Survey.
Exploring sequences: a graphical tool based on multi-dimensional scaling
A new tool for the graphical exploratory analysis of sequences is introduced and how these plots can be used to gain insights about the main features of sequences and about the relationships between sequences and external information is described.

  • 1 July 2008
New criteria to obtain classification trees for ordinal response variables are introduced and the hereby proposed methods are compared with the ordered twoing criterion via simulations.
A new measure of nominal‐ordinal association
A new measure for evaluating the strength of the association between a nominal variable and an ordered categorical response variable is introduced. The introduction of a new measure is justified by
Association of Age With Likelihood of Developing Symptoms and Critical Disease Among Close Contacts Exposed to Patients With Confirmed SARS-CoV-2 Infection in Italy
Only 26.1% of infected individuals younger than 60 years developed respiratory symptoms or fever greater than or equal to 37.5 °C, but 6.6% of infection participants aged 60 years or older developed critical disease.
Italian Version of the Physical Therapy Patient Satisfaction Questionnaire: Cross-Cultural Adaptation and Psychometric Properties
The Italian version of the Physical Therapy Patient Satisfaction Questionnaire (PTPSQ-I), developed through forward-backward translation, final review, and pre-final version showed good psychometric properties, and can be recommended with Italian-speaking outpatient populations.
Clustering work and family trajectories by using a divisive algorithm
Summary. We present an approach to the construction of clusters of life course trajectories and use it to obtain ideal types of trajectories that can be interpreted and analysed meaningfully. We
