Fairness in education: The Italian university before and after the reform

In 2001 the Italian tertiary education system embarked in a broad process of reform. The main novelty brought by the reform was a reduction of the length of study to get a first level degree together with the introduction of a two-years, second level, master degree. This paper aims at studying the effects of the reform in terms of fairness. To this end, we first define fairness criteria following a well developed theory of equality of opportunity, we then discuss existing inequality measures consistent with these criteria, we show their relationship, and adapt them to the educational framework. We finally employ this set of measures to show the evolution of fairness in the access to university in Italy before and after the reform. Although not all fairness measures we estimated show a higher degree of fairness after the reform, the large majority does, suggesting a positive effect of the reform under a vast range of possible definitions of fairness.     

The Evolution of Teaching Instruments and Their Use Between 1800 and 1930

At the beginning of the nineteenth century, the core of a typical teaching collection was composed by apparatus, which were very similar to the ones proposed in the eighteenth century by ‘s Gravesande, Nollet, Desaguliers and others lecturer demonstrators and makers. Since 1820 circa, new didactic instruments were introduced. Most of them concerned the fast developing branches of physics such as wave optics, electromagnetisms and acoustics. Instrument makers (and many scientists as well) were extremely prolific in inventing new devices for better demonstrating all the laws of physics and for clearly visualizing all its phenomena. Therefore, around 1900 all the most important German, French and British makers proposed in their thick catalogues thousands of didactic apparatus. But were all these instrument really used? Probably not. Many of them were acquired by schools and universities because they were considered “status symbol” marking the importance and the completeness of a collection. Others were simply shown as “tri-dimensional” illustrations. For various reasons, during the first decade of the twentieth century the number of available didactic instruments was drastically reduced. The introduction of student training laboratory, the increasing cost of labour and of materials after WWI, the needs of a more standardized production, the progresses of physics not only eliminated from the trade catalogues many of the classical but old fashioned instruments but also stimulated the use of modular and simpler didactic apparatus.     

A pilot project of a cancer patient library in Italy: results of a customer-satisfaction survey and its products

AIMS: The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. PATIENTS AND METHODS: A survey was developed to assess service functionality and quality from the users' viewpoint. During a 6-month period, a questionnaire was mailed to 194 patients and relatives who previously used the CIP-LP; 113 (58%) were returned and processed. RESULTS: Of the respondents, 91% were pleased with the CIP-LP and 95% would recommend the service to other people. The information obtained contributed to a clearer understanding of the illness and treatment (45% as first answer) and a better control of the situation (33%). Fifty-one per cent evaluated the information received as 'good', 42%'excellent' and 4%'of sufficient quality'. CONCLUSION: This survey shows the appreciation and usefulness in the users' perception of a specific hospital library for cancer patients and their relatives, providing an information service supplementary to doctor-patient communication.     

Using the Web as corpus for self-training text categorization

Most current methods for automatic text categorization are based on supervised learning techniques and, therefore, they face the problem of requiring a great number of training instances to construct an accurate classifier. In order to tackle this problem, this paper proposes a new semi-supervised method for text categorization, which considers the automatic extraction of unlabeled examples from the Web and the application of an enriched self-training approach for the construction of the classifier. This method, even though language independent, is more pertinent for scenarios where large sets of labeled resources do not exist. That, for instance, could be the case of several application domains in different non-English languages such as Spanish. The experimental evaluation of the method was carried out in three different tasks and in two different languages. The achieved results demonstrate the applicability and usefulness of the proposed method.

Query reformulation mining: models,patterns, and applications

Understanding query reformulation patterns is a key task towards next generation web search engines. If we can do that, then we can build systems able to understand and possibly predict user intent, providing the needed assistance at the right time, and thus helping users locate information more effectively and improving their web-search experience. As a step in this direction, we build a very accurate model for classifying user query reformulations into broad classes (generalization, specialization, error correction or parallel move), achieving 92% accuracy. We then apply the model to automatically label two very large query logs sampled from different geographic areas, and containing a total of approximately 17 million query reformulations. We study the resulting reformulation patterns, matching some results from previous studies performed on smaller manually annotated datasets, and discovering new interesting reformulation patterns, including connections between reformulation types and topical categories. We annotate two large query-flow graphs with reformulation type information, and run several graph-characterization experiments on these graphs, extracting new insights about the relationships between the different query reformulation types. Finally we study query recommendations based on short random walks on the query-flow graphs. Our experiments show that these methods can match in precision, and often improve, recommendations based on query-click graphs, without the need of users’ clicks. Our experiments also show that it is important to consider transition-type labels on edges for having recommendations of good quality.     

Effectiveness of bibliographic searches performed by paediatric residents and interns assisted by librarians. A randomised controlled trial

Background: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. Objectives: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real‐life clinical scenarios. Methods: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non‐assisted (control) group. Each participant searched Pub Med and other online sources, performing pre‐determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. Results: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8–33.2), in favour of the assisted group (P‐value, Mann–Whitney U test: 0.013). Conclusions: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.     

Dynamic sitting: Measurement and associations with metabolic health

Dynamic sitting, such as fidgeting and desk work, might be associated with health, but remains difficult to identify out of accelerometry data. We examined, in a laboratory study, whether dynamic sitting can be identified out of triaxial activity counts. Among 18 participants (56% men, 27.3 ± 6.5 years), up to 236 counts per minute were recorded in the anteroposterior and mediolateral axes during dynamic sitting using a hip-worn accelerometer. Subsequently, we examined in 621 participants (38% men, 80.0 ± 4.7 years) from the AGES-Reykjavik Study whether dynamic sitting was associated with cardio-metabolic health. Compared to participants who recorded the fewest dynamic sitting minutes (Q₁), those with more dynamic sitting minutes had a lower BMI (Q₂ = ?1.39 (95%CI = ?2.33;–0.46); Q₃ = ?1.87 (?2.82;–0.92); Q₄ = ?3.38 (?4.32;–2.45)), a smaller waist circumference (Q₂ = ?2.95 (?5.44;–0.46); Q₃ = ?3.47 (?6.01;–0.93); Q₄ = ?8.21 (?10.72;–5.71)), and a lower odds for the metabolic syndrome (Q₂ = 0.74 [0.45;1.20] Q₃ = 0.58 [0.36;0.95]; Q₄ = 0.36 [0.22;0.59]). Our findings suggest that dynamic sitting might be identified using accelerometry and that this behaviour was associated with health. This might be important given the large amounts of time people spend sitting. Future studies with a focus on validation, causation and physiological pathways are needed to further examine the possible relevance of dynamic sitting.     

Science or graduates: How do firms benefit from the proximity of universities?

This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies.
