Housework and childcare in Italy: a persistent case of gender inequality
This article focuses on the gender gap in housework and childcare in Italian couples. Italian women still carry out three-quarters of domestic work and two-thirds of childcare. We focus on three possible theoretical explanations for the persistence of the gendered division of labor: time availability, relative resources, and conformity with traditional gender ideology. Time Use data from the 2008/09 Survey edition have been used: we considered couples, married or in consensual unions, with at least one child under 14 years of age and with the mother employed
International survey of integrated financial sector supervision
Despite the intense debate on the advantages and disadvantages of adopting integrated supervision that has taken place in recent years, little is known about the experiences of countries that have adopted it and the obstacles and challenges they have faced to implement it. In an attempt to shed light on this area, the authors present the results of a survey conducted in a group of 15 countries that have adopted integrated supervision. After a brief review of the literature on integrated supervision, the authors examine four topics: 1) The reasons cited by this group of countries for establishing an integrated supervisory agency. 2) The scope of regulatory and supervisory powers of these agencies. 3) The progress of these agencies in harmonizing their regulatory and supervisory practices across the intermediaries they supervise. 4) The practical problems faced by policymakers in adopting integrated supervision. The survey revealed that the group of integrated supervisory agencies is not as homogeneous as it seems. Important differences arise with regard to the scope of regulatory and supervisory powers the agencies have been given. In fact, contrary to popular belief, less than 50 percent of the agencies can be categorized as mega-supervisors. Another finding is that in most countries progress toward the harmonization of prudential regulation andsupervision across financial intermediaries remains limited. Interestingly, the survey revealed that practically all countries believe they have achieved a higher degree of harmonization in the regulation and supervision of banks and securities companies than between banks and insurance firms. The survey also identified some practical problems faced by this group of countries in establishing their unified supervisory agencies. The authors discuss these problems, along with the practical lessons and recommendations provided by the 15 agencies to other countries considering integrated supervision, in the final section of the paper.Banks&Banking Reform,Insurance&Risk Mitigation,Housing Finance,Payment Systems&Infrastructure,Financial Intermediation,Banks&Banking Reform,Insurance&Risk Mitigation,Financial Intermediation,Housing Finance,Environmental Economics&Policies
Demographic Trends and Pensions in Italy: An Outlook for the Future
Projections of expenditures for old age pensions, survivor pensions, and disability pensions were made for the period 1985-2050 on the basis of future developments in the population structure by age, sex, and marital status. Four demographic scenarios were formulated: (i) a Benchmark scenario, with demographic rates kept constant at their 1980-84 level; (ii) a Fertility scenario, with a rise of the Total Fertility Rate (TFR) towards replacement level; (iii) a Mortality scenario, with reductions in mortality rates of 30 percent for females, and 45 percent for males; (iv) a Western scenario, which combines extreme demographic conditions of several West European countries: a TFR of 1.28, proportions never-marrying of one-third, one-third of marriages ending in divorce, and male and female life expectancies of 74 and 81 years, respectively.
The current pension system was combined with all four scenarios. Also, the impact of high female labor force participation, and a rise in the average age at retirement were investigated. The results indicate that changes in demographic conditions cannot prevent increases in and funding problems for pension expenditures in Italy. An increase in fertility has no effect on the pension system until 2030, when a larger generation will enter the labor force. Longer active periods for males and females will cause increases in pension expenditures in the future and are not long term solutions of the pension problem. Postponement of retirement age would help to balance the pension funds, but depends on the economic situation and on the labor market
Test_A il tuo mal di testa. Report d’indagine
In questo lavoro si riportano i principali risultati di una ricerca quantitativa volta a testare, attraverso la somministrazione di questionari a più livelli –pazienti (n= 2500) e medici (n= 100) -un semplice strumento di misurazione della percezione individuale della ricorrenza e della gravità del sintomo delle cefalee, dell’utilizzo di farmaci e del ricorso alle strutture sanitarie di riferimento (Farmacia, MMG e Centri Cefalee). L’indicatore di sintesi così costruito, denominato “Test_a”, si rivela in grado di guidare il paziente nella autovalutazione del livello di gravità del proprio sintomo e nel come affrontarlo; nello stesso tempo, lo strumento proposto può essere di ausilio a farmacisti e medici di medicina generale (MMG), potenziandone la capacità di intercettare, sensibilizzare e orientare il paziente stesso ad una corretta gestione di emicrania e cefaleaThis report contains the main results of a quantitative research aimed at testing a simple tool for detecting the individual perception of recurrence and the severity of the symptom of headaches and how it is dealt with in terms of drug use and the use of appropriate reference health structures (general practitioner and headache centers). The survey has been carried out in Italy, April-June 2017, on a sample of 2,500 patients of a total of 100 general practitioners. Two different questionnaires have been submitted, one self-compiled by the patient him/herself with items aimed at testing a measurement scale, and the second in front of the physician, in order to evaluate the level of clarity and satisfaction of the first card
Tangle-bearing neurons survive despite disruption of membrane integrity in a mouse model of tauopathy
Neurofibrillary tangles (NFTs) are associated with neuronal loss and correlate with cognitive impairment in Alzheimer disease, but how NFTs relate to neuronal death is not clear. We studied cell death in Tg4510 mice that reversibly express P301L mutant human tau and accumulate NFTs using in vivo multiphoton imaging of neurofibrillary pathology, propidium iodide (PI) incorporation into cells, caspase activation and DNA labeling. We first observed that in live mice a minority of neurons was labeled with the caspase probe or with PI fluorescence. These markers of cell stress were localized in the same cells and appeared to be specifically within NFT-bearing neurons. Contrary to expectations, the PI-stained neurons did not die over a day of observation; the presence of Hoechst-positive nuclei in them on the subsequent day indicated that the NFT-associated membrane disruption suggested by PI staining and caspase activation do not lead to acute death of neurons in this tauopathy model. This unique combination of in vivo multiphoton imaging with markers of cell death and pathologic alteration is a powerful tool for investigating neuronal damage associated with neurofibrillary pathology
Time evolution of the Partridge-Barton Model
The time evolution of the Partridge-Barton model in the presence of the
pleiotropic constraint and deleterious somatic mutations is exactly solved for
arbitrary fecundity in the context of a matricial formalism. Analytical
expressions for the time dependence of the mean survival probabilities are
derived. Using the fact that the asymptotic behavior for large time is
controlled by the largest matrix eigenvalue, we obtain the steady state values
for the mean survival probabilities and the Malthusian growth exponent. The
mean age of the population exhibits a power law decayment. Some Monte
Carlo simulations were also performed and they corroborated our theoretical
results.Comment: 10 pages, Latex, 1 postscript figure, published in Phys. Rev. E 61,

The Heumann-Hotzel model for aging revisited
Since its proposition in 1995, the Heumann-Hotzel model has remained as an
obscure model of biological aging. The main arguments used against it were its
apparent inability to describe populations with many age intervals and its
failure to prevent a population extinction when only deleterious mutations are
present. We find that with a simple and minor change in the model these
difficulties can be surmounted. Our numerical simulations show a plethora of
interesting features: the catastrophic senescence, the Gompertz law and that
postponing the reproduction increases the survival probability, as has already
been experimentally confirmed for the Drosophila fly.Comment: 11 pages, 5 figures, to be published in Phys. Rev.
A Bit-String Model for Biological Aging
We present a simple model for biological aging. We studied it through
computer simulations and we have found this model to reflect some features of
real populations.Comment: LaTeX file, 4 PS figures include
