Claudia Marin, born in Bari the 11.17.1979, works as a researcher of Statistics (SECS-S/01) at the
Department of Educational Sciences, Psychology and Communication, University of Bari from 16 July 2006.
1. Academic career
Confirmation in 2010 in the role of researcher in Statistics (SECS-S/01) at the Faculty of Education,
University of Bari
2008 PhD in Man and Environment with a thesis entitled "Survey on the quality of student life at the
University of Foggia" at the University of Foggia.
2006 Winner of the competition for a researcher in Statistics (SECS-S/01) at the Faculty of Education,
University of Bari
2004 Winner of a scholarship for a PhD inter-"Man and Environment" at the University of Foggia.
2003 Degree in Economics from the University of Bari
1998 Diploma in classical studies.
2. Teaching Activities
Since the academic year 2006/2007 is responsible for the course of Research Techniques and Data
Processing of the degree in Pedagogical Sciences.
The educational activity has also resulted in the development of core courses of Statistics for doctoral
students belonging to a Ph.D. "Design and evaluation of educational processes" of the Faculty of Education.
3. Scientific Activities
The scientific activity of Claudia Marin has developed on some main lines: the first essays regarding the
study of quality of life (1 monograph and publications 2:04), the next orientation of the research is directed,
at first, on the analysis of the main distribution models to derive the expression of the variance of the mean
difference for random samples of variables Student (publication 3) and the expression of the simple average
deviation from the median of the distribution of Dagum (publication 5), and recently , turned towards the use
of the integral of Dagum which dynamic model of economic and social phenomena and, in particular, of the
populations (Publication 6).
The first line of research has arisen and has been deepened during his PhD in "Man and Environment" (XX
cycle) held at the Faculty of Economics and Business, University of Foggia during the academic years 200405, 2005 - 06, 2006-07 and is still actively followed.
The survey on the perception of quality of life (QOL) was carried out on students of the 5 faculties of the
University of Foggia (Agriculture, Law, Economics, Humanities, Medicine and Surgery) by administering a
questionnaire that investigated the relevant aspects of student life in Foggia. The choice of university life as a
field of investigation led to consider both the urban environment that the university and, therefore, to identify
specific aspects in which it may be limited perception of QoL of respondents. We wanted to investigate the
life in your city and on the perception of urban services, means of transport and the quality of the urban
environment, on leisure and on the perception of the facilities made available to students on the study and the
personal aspirations of these last. Thanks to the application of factor analysis identified six factors were
defined as the "well-being index urban", "index of perception of security", "index of lawlessness", "service
index", "index of leisure" and "index of usability of the neighborhood." The results produced by this
investigation have not been very positive for the city of Foggia and the most important towns in his province
since the collective interviewed showed a poor life satisfaction in the fabric of the city ("urban livability
index" equal to 5 , and 07 "index of urban malaise" of 6,32).
From the academic year 2008-09, the research has contributed to obtaining the formal expression of the
variance of the sample mean difference for the Student's distribution model in terms of the parameter g
(degrees of freedom) and the amplitude sample n.
Recently, the scientific activity has involved the study of the behavior of the scale and shape parameters in
terms of variability in terms of absolute and relative variability by means of the expression of the simple
average deviation from the median for the Dagum distribution.
Deepening the lines of investigation Amoroso (the division of the logistics cycle into four phases that
characterize the demographic development, stages he calls the spring, summer, autumn, winter) and
Chiassino (the instantaneous rate of development of various demographic models, methods calculation of
parameters of the same, as well as the concrete application to the dynamics of the populations of some
countries), the last line of research is proposed in order to use the full length of the Dagum distribution
model as a model of development of economic and social phenomena . This model will also have been
studied in the articulation phases and the instantaneous rate of growth and it has been possible to highlight
similarities and differences between the integral of Dagum and the logistic curve in canonical form.
The scientific activity has also articulated in annual research projects, financed with funds from the
University, which were:
