New Indicators for investigating the integration of Sapienza graduates into the labour market
No full textThe labour market demand for the employability skills and knowledge of Sapienza graduates
can now be analysed through the new administrative archive, UNI.CO, which was built by
merging the Sapienza University of Rome archives with those of the Italian Mini
stry of Labour.
Different types of graduate integration into the subordinate and para-subordinate labour market
are identified, and variables for the integration into job positions are defined in coherence with
the university career path. In this study, we
propose some variables which can influence the
probability of “job success” in terms of Sapienza graduates best employment status. The
evolution of the job contract type, actual job duration and professional qualifications, is studied
through a longitudinal analysis based on new specific synthesis indicator
Assessing Sapienza University alumni job careers : enhanced partial least squares latent variable path models for the analysis of the UNI.CO administrative archive
No full textFor several years, the Italian universities have been urged to better understand the characteristics of labour demand for their alumni. For this purpose periodic reports
of the results of sample surveys are produced by institutions or private entities.
These studies are detected directly from the alumni and their employment status after graduation (the most common sample surveys coming from Inter-University Consortium AlmaLaurea). These results constitute important information for students, families and universities. The sample surveys are based on studies that take place at a distance of six months and of two years from the date of graduation. The alumni are interviewed regarding their satisfaction as well as to obtain information on their employment situation. Obviously, all ex post assessments provide us with a lot of information to define overall judgements regarding the educational career but also their employment status.
Of course, the definition of a graduate's employment status is not unique. With
regards to Italy, the ISTAT records the status of employment when the individual performs, in a reference week, at least one hour of paid work (regulated by a registered contract) regardless of the type of contract and the regularity of employment.
Timing is certainly a critical element: studies too close to the end of the educational
experience do not sufficiently reect the students' rethinking of their educational
lives. However, if the surveys are too far from this experience, the rethinking can itself be strongly influenced by exogenous factors.
The labour market demand for the employability skills and knowledge of Sapienza graduates can now be analysed through the new administrative archive called UNI.CO, which was built through a record-linkage between the Sapienza University of Rome archive with those of the Italian Ministry of Labour and Social Policy. The UNI.CO archive has allowed us to evaluate all the signed contracts obtained by Sapienza
graduates in addition to full information on all the enterprises and institutions that
offered these contracts. This archive allows us to perform a statistical analysis on more sophisticated and robust (and more reliable) details than the standard analysis based on sample surveys. In our study we have, therefore, used objective real data unaffected by any emotional influence. Another important feature is that the data from the UNI.CO archive allow us to study the evolution of alumni throughout the observation period and therefore to analyse changes in job qualifications (differently from the common sample survey supply information about the status of alumni at some fixed point in time (like a photograph)).
In this thesis we adopted the administrative UNI.CO archive in order to be able to present the theme of the integration of Sapienza University of Rome alumni into the employee and para-subordinate labour market with more sophisticated and powerful details in relation to the standard analysis based on sample surveys. Moreover, the data of the UNI.CO archive allow us to also study the evolution of alumni throughout the observation period and therefore to analyse the changes in job qualifications. The study of the integration into the labour market of Sapienza alumni has been analysed by adopting the Non-Metric PLSPM method which allows us to handle a large dataset with numerical, nominal and ordinal variables. This technique recently proposed by Russolillo (2012) and now available in the plspm R-package, is characterized by the opportunity to analyse at the same time variables observed in different measurement scales, to investigate the non linearity and to work without distributional hypotheses. The Non-Metric PLSPM has demonstrated a remarkable
adaptability to handle the UNI.CO large dataset and we have found that the quantifications of the original data obtained by the procedure are properly carried out using monotone transformations showing the remarkable fact that it is possible to discard the hard assumption of linearity in favor of the milder assumption of monotonicity.
In this thesis, we have modified the inner structure of the Non-Metric PLSPM to implement the possibility of modeling binary endogenous latent variables through a logistic regression and then we have introduced the ROC curve for the model validation. This implementation is applicable in the case of blocks with only one MV and this is binary, therefore LVs have a binary structure and the weight and the
loading are unitary.
We have addressed the study of the integration into the labour market of Sapienza alumni by developing a few models.
The first one concerns the quantitative study of the job success of the masters degree alumni of the Sapienza University who belong to the engineering disciplinary sector in terms of quality of work. In particular, we studied indicators of job success to estimate their relationships with educational and job curriculum. These indicators have been constructed defining the concept of optimal contract based on a contract with the characteristics of permanent position, highly qualified professional position identified using the ISCO classification and the actual duration more than or equal to 8 months. The concept of quasi-optimal contract is similar to the optimal definition without the condition of permanent position. The high values of the measurement model have confirmed that the optimal and quasi-optimal indicators are
discriminant to the construction of the Job Success block.
The second and the third models have been built in order to study the job career in terms of the contract type and quality evolution in the three years after graduation. For these studies we selected from the UNI.CO dataset, independently from the disciplinary group, two sets of data: alumni who at the time of the master's degree had not yet obtained an active contract (non-workers studied by the second
model) and alumni who at the time of the master's degree had obtained an active contract (workers studied by the third model). The main purpose we addressed is to model, in the PLS-PM framework, the contract type and job professional quality evolution as latent variables to be studied in relation to educational curriculum, age, initial experience and tendency to evolve. The two models adopted consist essentially of four concepts: the university evaluation, the initial job experience, tendency to evolve and the career evolution. The career evolution is monitored by two constructs: one for the job professional evolution and the other for the job contractual
evolution. We have found that in both the models there is a strong influence of the
initial job experience and of the tendency to evolve over the job career, while the university evaluation at the level of the master's degree is less important. The age
at the master's degree has a marginal effect in the model for non-workers while it disappears for workers.
It is remarkable that the implementation of the logistic regression, in all the presented models, has shown a good classification measured in terms of high AUC values.
The overall frame that arises from these studies is that when there is a natural individual aptitude of the alumni to change job, this tendency plays a positive important
role with the aim of obtaining a satisfactory job; on the other hand, the university
path of Sapienza alumni does not seem to have a large direct influence on their job career.
It is clear that our analysis can be considered as a starting point for further studies aimed to investigate the relationships between the world of labour and that of the university education in order to improve the efforts that should be made to integrate these two worlds

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
