9 Italy between an ageing population and continued immigration
Italy is one of the countries around the globe with the lowest level of reproduction, with the latest nest leaving, the highest average life expectancy at birth and the highest level of an ageing populationand immigration is continuously gaining importance. This is the picture that the report on the Italian demographic situation at the beginning of the 21st century ‘Rapporto sulla popolazione italiana - L’Italia all’inizio del XXI secolo’ is drawing. The association of Italian demographers in the Italian Statistical Society The population of Italy continues to grow only due to continuous immigration. Between 2002 and 2005 Italy’s population grew by 440,000 people per year. As predicted, the natural balance between births and deaths was negative and close to –15,000 per year. The population growth is due to the effect of the ‘Bossi-Fini’ law and new immigrants and the regularisation of foreigners residing illegally in Italy The information regarding immigration is the most interesting evidence presented in the report on the Italian demographic situation, realised by the association of Italian demographers in the Italian Statistical Society and edited by Giuseppe Gesano, director of research at the Institute of Research on Population and Social Policies of the National Research Council, Fausta Ongaro (University of Padova), Alessandro Rosina (Catholic University of Milan). Several Italian demographers contributed to the report. Between 2002 and 2005 170,000 children were born to women of non-Italian citizenship, representing about 8 % of all births. The number of foreign births is growing rapidly, like the foreign population: in 1991 the percentage of the foreign population was below 0.6 %, which quadruplicated to 2.3 % in 2001. Today the percentage lies between 4.5 % (based on an official foreign resident population of 3.5 millions) and 6.6 % (based on an estimation of the foreign population including the illegal immigrants). The foreign population contributes to a reduction of an ageing population in Italy: without them the population of 65 years and older would represent already more than one fifth of the total population. The average age of the foreign residing population is 31 years, against the average age of 43 years of the Italian population. Their reproduction is double the Italian one: in 2004 the women of foreign citizenship had an estimated total reproduction rate of 2.61 children, whereas the total reproduction rate of Italian women was From a demographic point of view, the vitality of a population is measured through its capacity of renewal, or through the fact that each generation is reproducing itself through the same amount of persons. In Italy this has not happened for the last 30 years, but Italy’s population rather than shrinking is growing weakly due to (1) the momentum of its age structure with many persons in a reproductive age, (2) the gain in average life expectancy at birth (8.2 years for men and 7.5 years for women) and (3) the immigration influx. Italy is the country with the highest percentage of elderly: United Nations estimates put the 65 and older in 2005 at 20 % of the total population, and the latest estimates in 2006 at 19.8 %. Whereas at the beginning of the 1990’s the percentage of the elderly in the countries of the EU hovered around 15 %, with Italy and Spain somewhat younger, in 2005 Italy passed Germany and became the country with the highest percentage of the population at 80 years and older (5.1%). In the future, it is believed, that these percentages will grow. One important factor of the ageing population is the relatively high level of average life expectancy at birth with above 83 years in the case of women and 77 years in the case of men. Fertility in Italy continues to be closely linked to the process of nest leaving and the formation of new married couples. This process shows a strong and continuous delay. The propagation of higher education and economic activity among young women is experienced as an obstacle to union formation and In only 10 years, from 1993 to 2003, looking at the decisive age group of the 25 to 34 years old, the ratio of men having a family with children diminished from one in three to one in five, and the ratio of women having a family with children diminished from one in two to one in three. During the last 30 years the age for first marriages increased by 5.5 years for women and 4.2 years for men, reaching 29.4 and 32.2 years, respectively. And the majority of the non-married young adults continue to live in the parental home: 38 % of the 30 to 34 years old men and 21 % of women of the same age group are living with their parents. The delays accumulated in the process of forming an own family are leading to few and late childbirths: the mean age at childbirth of women in Italy is 30.8 years (31.1 for Italian women and 27.4 for foreign women). During the last few years the tendency to have children at a later age continued to grow. A process of convergence can be observed between the Mezzogiorno (Southern Italy) and Central-Northern Italy. Regarding reproduction: the traditional disparities disappeared between 1995 (1.06 children per women in the North against 1.43 in the Mezzogiorno) and 2005, when in both Italian subdivisions women have on the average 1.32 children. The increase of reproduction in Northern regions is partly due to the contribution Bollettino della Comunità Scientifica in Australasia
of foreign women. Regarding mortality: the Northern regions managed to remove the disadvantage they had through an increase in average life expectancy at birth and at older ages (+2.6 years for 65 years old between 1991 and 2005) higher than in the southern regions (+2.1 years). This increase can be attributed predominantly to the higher reduction of causes of mortality ‘cardiovascular system’ and ‘cancer’ in the Centre-North. In the Central-Northern regions also life expectancy in good health increased more than the Southern regions: 65 year old men increased their value during the period of observation by 4 years in the Centre-North and by 2.8 years in the Mezzogiorno, whereas the corresponding values for women are 3.6 against 2.5 years. This brings the value of life expectancy in good health of the 65 year old men to about 14 years in the North-East and in the Centre, 13.7 in the North-West and 13.1 in the Mezzogiorno, but it is considerably lower for 65 year old women of the South (13.5 years) compared to the ones living in the The economic weakness of the Mezzogiorno emerges again with a negative net-migration with Central- Northern Italy (between –40,000 and –50,000 per year), and with a minor attractiveness regarding international immigration of foreigners (6.2% of the total population of the Centre-North are foreigners against 1.5% in the Mezzogiorno). In recent years immigrants are arriving predominantly from Eastern Europe. Their duration of stay is still short compared to the ‘traditional’ flows of Philippines, Tunisians, Senegalese and Moroccans. Nevertheless there are some first signs of definitive settlements with the formation of families and an increasing number of children born in Italy. The second generation of foreigners, or the persons born in Italy with at least one foreign parent, were estimated to reach 550 to 650 Compared to other European countries Italy is at the vanguard regarding the trends in longevity and fertility, but the Italian population is following more traditional patterns regarding the trends in household structures and reproductive models. For example, few young adults are living on their own or are cohabitating. The cohabitation of unmarried couples, fairly widespread in northern Europe, is still the exception in Italy. Civil marriages (only one out of three marriages in 2005), separations and divorces are increasing. However, only one out of seven marriages are ending in divorce in Italy, compared to a third or half in other European countries. As a consequence, there are few households with small children with a single parent (662 thousand); there are few brides or grooms celebrating a second wedding (8%); and there are few reconstituted families (721 thousand). The percentage of births to unmarried mothers, which doubled lasting recent years, is still below 15 %, when in many other European countries this percentage rises above 50 %. Giuseppe Gesano of Irpps-Cnr concludes that the challenge of an ageing population has to be met with innovative ideas, leaving behind preconceptions and privileges. Immigrants have to be viewed as a stable component of the population through measures, which integrate and recognise this population group, especially the second generation. It is necessary to facilitate and accelerate the passage of the young to adulthood and autonomy regarding the formation and enlargement of the family, giving space to new family models. The North-South disparities regarding health care and employment opportunities have to be Further information: Giuseppe Gesano, Institute of research on Population and Social Policies – Italian National Research Council (Irpps-Cnr) [email protected] “Rapporto sulla popolazione italiana - L’Italia all’inizio del XXI secolo, edited by Giuseppe Gesano (Irpps- Cnr), Fausta Ongaro (University of Padova), Alessandro Rosina (Catholic University of Milan). Bologna: Il 9 TWAS, illycaffè announce Trieste Science Prize winners, 2007
An eminent Mexican biologist, whose research helped to spur the creation of the first genetically modified plants, and an internationally renowned Indian chemist, whose innovative laboratory techniques have led to the synthesis of more than 50 natural products, have been awarded the Trieste Science Prize for, 2007. The Trieste Science Prize, administered by TWAS and funded by illycaffè, provides international recognition to outstanding scientists living and working in the developing world. Winners share a US$100,000 cash Luis Rafael Herrera-Estrella, director of the National Laboratory for Genomics of Biodiversity and professor of plant genetic engineering at the Centre of Research and Advanced Studies in Irapuato, Mexico, helped to pioneer the field of plant molecular biology and genetic engineering. Plant transformation techniques developed by Herrera-Estrella and his colleagues have had a significant impact on the commercial production of genetically modified (transgenic) plants currently grown on more than 100 million hectares Herrera-Estrella's work has largely focused on crop species of economic importance to Latin America, including asparagus, maize and papaya. In addition, his analysis of the molecular mechanisms of toxins, Bollettino della Comunità Scientifica in Australasia
produced by the disease-causing bacterium Pseudomonas syringae pv phaseolicola, has led to the development of transgenic beans resistant to the disease. Herrera-Estrella has recently turned his attention to understanding the molecular mechanisms that make it possible for plants to tolerate toxic concentrations of aluminum and, more generally, that enable plants to adapt to nutrient-deficient soils. This is a critically important issue in Latin America, where some 500 million hectares of farmland are deficient in phosphorus, an essential nutrient for healthy plant growth and crop Goverdhan Mehta, CSIR Bhatnagar fellow and honorary professor at the Department of Organic Chemistry at the Indian Institute of Science in Bangalore, and distinguished research professor at the University of Hyderabad in India, is a world-renowned chemist who has made breakthrough contributions in a variety of His wide-ranging interests include the synthesis of biologically significant and architecturally challenging natural products; the design of novel molecules; the study of stereoelectronic effects; and super molecular chemistry. His synthesis techniques have been widely praised for their elegance and originality. Otteliones A and B, currently being tested for their anti-tumor activity, are among the 50 complex and biologically active natural products that Mehta and his group have synthesized. Mehta's work has led to patents for hybrid drugs for the treatment of cancer that combine the drugs' conventional cytotoxic action with the ability to 'switch on' the drugs in the desired location using light as a stimulus. He and his group have also synthesized carbon compounds that may have potential applications in Beyond the laboratory, Mehta has made significant contributions to science education and science policy in India and abroad. He is currently president of the International Council for Science (ICSU) in Paris, France, and a member of the Scientific Advisory Committee to the Prime Minister of India. "Trieste Science Prize winners," says Jacob Palis, president of TWAS, "put a spotlight on the enormous impact that scientists from the developing world are making to international science. Their efforts are not only helping their nations to advance but are also making our global community a better place." "illycaffè," says Andrea Illy, the company's president and chief executive officer, "is pleased to honour scientists who are making significant contributions to society. The Trieste Science Prize symbolizes excellence. The success of the recipients has enriched both their societies and ours."

Paola Maccioni, a 28-year-old PhD student at the Institute of Neuroscience, National Research Council [Consiglio Nazionale delle Ricerche (CNR)], Cagliari, Italy, has been awarded one of the five fellowships “L’Oreal Italy for women and science –, 2007”. This fellowship will partially support Dr. Maccioni’s research on the role of the GABAB receptor in the mediation of several alcohol-motivated behaviors, including drinking and seeking behaviors. Dr. Maccioni will run her studies using validated techniques of behavioral pharmacology and a rat line, named Sardinian alcohol-preferring (sP), bred at the CNR Institute of Neuroscience for excessive alcohol consumption. These rats – that constitute one of the few rat lines selectively bred worldwide for their extremely high alcohol consumption – represent a unique experimental model for studies aimed at identifying drugs with theraputic potential in the field of alcohol abuse and alcoholism. Their use has already led to the successful identification of gamma-hydroxybutyric acid and, more recently, the GABAB receptor agonist, baclofen, as Dr. Maccioni is currently focusing her research on the characterization of the anti-alcohol properties of a new class of GABAB receptor ligands: the positive allosteric modulators. These drugs facilitate binding of the neurotransmitter GABA with its own receptor, in turn potentiating GABAB receptor-mediated neurotransmission. Data collected to date by Dr. Maccioni and her colleagues suggest that the positive allosteric modulators of the GABAB receptor reproduce most of baclofen’s effects, including the suppressing effect on alcohol intake in rodents, without reproducing the adverse effects. Dr. Maccioni’s work is supervised by Drs. Gian Luigi Gessa and Giancarlo Colombo; other investigators of the CNR Institute of Neuroscience, including Drs. Mauro Carai and Carla Lobina, contribute to this research Contact: Dr. Paola Maccioni [email protected] 9 Best Paper Award to Fabrizio Silvestri at the 29th European Conference on
Information Retrieval conference.
Fabrizio Silvestri, a researcher at the “Institute for Information Science and Technologies” of the Italian National Council of Research (CNR), is the recipient of the Best Paper Award (sponsored by Yahoo! Research) at the 29th edition of the European Conference on Information Retrieval held in Rome in June, Bollettino della Comunità Scientifica in Australasia
2007. Fabrizio Silvestri's paper entitled "Sorting Out the Document Assignment Problem" deals with a common problem in Information Retrieval Indexing: compressing the index structure. The nice feature of the solution proposed in the paper is that it is very straightforward yet extremely effective. In the case of collections of Web Documents, in fact, we can enhance the performance of index compression algorithms by simply assigning identifiers to documents according to the lexicographical ordering of the URLs. Roughly speaking the paper highlights the correlation between URL string similarities and content similarities. The solution proposed can, thus, be effectively plugged into existing search systems without any particular pain. Further information: [email protected] http://hpc.isti.cnr.it/~silvestr
