Problematic mobile phone use in adolescence:a cross-sectional study
Aim: In recent years, mobile phone use has become increasingly common among Italian youth, while a growing scientific literature has been identifying the occurrence of a problematic mobile phone use which seems to share some features of other conditions often referred to as behavioural addictions. The study aimed to assess the prevalence of problematic mobile phone use in a population of Italian adolescents and its association with other behavioural addictions. Subjects and methods: The Mobile Addiction Test (MAT) was administered to 2,790 high school students from Barletta, an Italian town, together with the South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA), the Compulsive Buying Scale (CBS), the Internet Addiction Test (IAT), the Exercise Addiction Inventory (EAI), the Work Addiction Risk Test (WART). Results: MAT scores fitted a Gaussian distribution model. Scores ≥ 17 was found as a cut-off value over which identifying problematic mobile phone users. Overall prevalence of problematic mobile phone use was 6.3%; this condition was associated with other behavioural addictions like compulsive buying. Conclusion: Problematic mobile phone use in adolescence should become a public health issue, and it could be a cause of health problems and social costs. © 2011 Springer-Verlag
Self-exciting threshold binomial autoregressive processes
We introduce a new class of integer-valued self-exciting threshold models,
which is based on the binomial autoregressive model of order one as introduced
by McKenzie (Water Resour Bull 21:645–650, 1985. doi:10.1111/j.1752-1688.1985.
tb05379.x). Basic probabilistic and statistical properties of this class of models are
discussed. Moreover, parameter estimation and forecasting are addressed. Finally, the
performance of these models is illustrated through a simulation study and an empirical
application to a set of measle cases in Germany

Crítica de la razón neocolonial
El giro decolonial ha venido constituyéndose en el paradigma de la crítica en América Latina, instituyendo la idea de que es la única forma posible del pensamiento más avanzado. Sin embargo esta presentación tiene varios problemas.
Con la crítica al eurocentrismo, la reivindicación del lugar de enunciación y la pretensión de retorno a epistemes prehispánicas o indígenas, establecen una prespectiva de rechazo a grandes tradiciones de pensamiento europeas con argumentos que mezclan críticas justificadas al eurocentrismo con reivindicaciones chauvinistas y populistas.
Se requiere de proyectos de utopía social que permitan a los latinoamericanos establecer prioridades de lucha política, organizar la sociedad en formas adecuadas y centralizadas y establecer programas con prioridades específicas y, como señalan algunas feministas decoloniales, retornar a la noción de totalidad. De nada sirven proyectos que renuncian al humanismo y a la perspectiva universal, pues es esta coyuntura mundial el destino de la especie pende de un hilo.

Behavioural addictions in adolescents and young adults: results from a prevalence study.
Our study aims to assess the prevalence of behavioural addictions in an adolescent
population, evaluating the effects of gender and age, and to assess the correlations
among different behavioural addictions. 2853 high school students were assessed in order
to evaluate the prevalence of behavioural addictions such as Pathological Gambling (PG),
Compulsive Buying (CB), Exercise Addiction (EA), Internet Addiction (IA), and Work
Addiction (WA), in a population of Italian adolescents. The South Oaks Gambling Screen-
Revised Adolescent (SOGS-RA), the Compulsive Buying Scale (CBS), the Exercise
Addiction Inventory (EAI), the Internet Addiction Test (IAT), and the Work Addiction
Risk Test (WART), were compiled anonymously by the students. Overall prevalence was
7.0% for PG, 11.3% for CB, 1.2% for IA, 7.6% for WA, 8.5% for EA. PG and EA were
more common among boys, while gender had no effect on the other conditions. CB was
more common among younger (8 years old) students. The scores of all of these scales
were significantly correlated. The strong correlation among different addictive behaviours
is in line with the hypothesis of a common psychopathological dimension underlying these
phenomena. Further studies are needed to assess personality traits and other clinical disorders
associated with these problems behaviours
