Italian adolescents’ first romantic relationships: an explorative study

Recently collected retrospective data (from 2000-2001) on Italian university students are analyzed to find out the most significant factors that accelerate or delay the entrance into a first couple rela-tionship for teenagers. Intensity regression analysis is used to test factors that either proved to be noteworthy from previous analyses or are supposed to be significant from a theoretical point of view. Unobserved heterogeneity is included in the model to take into account the characteristics of individuals that are not measured or that are not measurable. The following results arise: age is highly significant, with a decreasing hazard after age 19. The influence of family, a strong institu-tion in Italy, is noticeable. Poor communication with parents is negatively associated with entrance into the first romantic relationship while tolerance of a son’s behaviors is positively associated.. The social life of a young person also shapes this event: shyer adolescents had a lower relative risk compared to their contemporaries who had many leisure interests and a wider friendship network. As expected, lower satisfaction with self-appearance exerts a negative weight on the hazard. Fi-nally, unobserved heterogeneity is not found to be significant in the model.

Lowest-Low Fertility: Signs of a recovery in Italy?

This study aims to describe the process of birth postponement and recovery in Italy, a country with persistent very low fertility levels. The case of Italy is particularly significant given that this country carries great demographic weight in "Southern Europe"; an area characterized by cultural and institutional specificities which have important implications for the timing of family formation and the final number of children. We use data recently published by the Italian National Institute of Statistics (Istat), applying a cohort approach to show changes in CTFRs and the timing of births for the 1950-1980 cohorts. In order to further evaluate the evolution of Italian “fertility ageing†across social groups (with a focus on female education) we also use individual level data from the 2003 Istat multipurpose survey “Famiglia e soggetti socialiâ€. We find that a recovery is presently in progress in the northern regions of Italy, even if not all postponed births are recovered. As expected, signs of recovery are above all evident among the youngest generations and more educated women.cohort fertility, education, fertility recovery, Italy, low fertility

Risk Assessment of a Wind Turbine: A New FMECA-Based Tool With RPN Threshold Estimation

A wind turbine is a complex system used to convert the kinetic energy of the wind into electrical energy. During the turbine design phase, a risk assessment is mandatory to reduce the machine downtime and the Operation & Maintenance cost and to ensure service continuity. This paper proposes a procedure based on Failure Modes, Effects, and Criticality Analysis to take into account every possible criticality that could lead to a turbine shutdown. Currently, a standard procedure to be applied for evaluation of the risk priority number threshold is still not available. Trying to fill this need, this paper proposes a new approach for the Risk Priority Number (RPN) prioritization based on a statistical analysis and compares the proposed method with the only three quantitative prioritization techniques found in literature. The proposed procedure was applied to the electrical and electronic components included in a Spanish 2 MW on-shore wind turbine

Female participation in African agricultural research and higher education: New insights

Female farmers play a vital role in African agriculture, accounting for the majority of the agricultural workforce. However, agricultural research and higher education are disproportionately led by men. There is an urgent need for greater representation of women in the field of agricultural science and technology (S&T) in Sub-Saharan Africa. Female scientists, professors, and senior managers offer different insights and perspectives to help research institutes to more fully address the unique and pressing challenges of both female and male farmers in the region. Gender-disaggregated data on S&T capacity are scarce, often lack sufficient detail, and focus more generally on S&T rather than on agriculture specifically. Data are not always comparable due to different methodologies and coverage. The Agricultural Science and Technology Indicators (ASTI) initiative and the CGIAR Gender & Diversity (G&D) Program partnered together to address this information gap. This report presents the results of an in-depth benchmarking survey on gender-disaggregated capacity indicators, covering 125 agricultural research and higher education agencies in 15 countries in Sub-Saharan Africa. This is the first study of its kind to present detailed human resources data on female participation in agricultural science, the main findings of which include the following: • Total capacity in terms of the professional staff employed at the agricultural research and higher education agencies included in this study increased by 20 percent between 2000/01 and 2007/08, and women constituted almost half of this capacity increase. The female population of professional staff grew by eight percent per year on average, which is four times higher than the comparable rate of increase for the male population, indicating that the gender gap in African agricultural sciences is closing. • The proportion of female professional staff employed at the sample agricultural research and higher education agencies increased from 18 percent in 2000/01 to 24 percent in 2007/08, but fewer women have advanced degrees compared to their male colleagues. In 2007/08, for example, 27 percent of the sample’s professional women held PhD degrees compared with 37 percent of the sample’s professional men. • Of concern, about two-thirds of the overall (female and male) capacity increase comprised staff holding only BSc degrees, indicating that the overall quality of capacity in agricultural research and higher education is declining in some Sub-Saharan African countries. Notably, the total number of male professional staff trained to the MSc level declined between 2000/01 and 2007/08; however, more in-depth analysis is needed to explain the underlying causes of these shifts and to what degree they represent structural changes. • Levels of female participation in agricultural research and higher education among the sample agencies were particularly low in Ethiopia (6 percent), Togo (9 percent), Niger (10 percent), and Burkina Faso (12 percent). Shares of female professional staff were much higher in South Africa, Mozambique, and Botswana (32, 35, and 41 percent, respectively). • The female share of students enrolled in higher agricultural education was higher than the female shares of professional staff employed at the agricultural research and higher education agencies in most cases, but a significant proportion of the female students concerned were undertaking only BSc-level studies (83 percent). • Only 14 percent of the management positions were held by women, which is considerably lower than the share of female professional staff employed at the sample’s agricultural research and higher education agencies (24 percent). • The pool of female staff is much younger on average than the pool of male staff. • The prevalence of female professional staff is comparatively higher in fields related to life and social sciences, and comparatively lower in fields involving areas traditionally thought of as “hard science”, such as engineering.agricultural R&D, Sub-Saharan Africa, female participation, S&T capacity, agricultural higher education,

Revisiting Alkali Metals As a Tool to Characterize Patterns of Mosquito Dispersal and Oviposition.

Mark-recapture methods constitute a set of classical ecological tools that are used to collect information on species dispersal and population size. These methods have advanced knowledge in disparate scientific fields, from conservation biology to pest control. Gathering information on the dispersal of mosquito species, such as Aedes aegypti, has become critical since the recognition of their role as vectors of pathogens. Here, we evaluate a method to mark mosquitoes that exploits the rare alkali metals rubidium (Rb) and caesium (Cs), which have been used previously to mark adult insects through feeding. We revised this method by adding Rb and Cs directly to water in which the immature stages of Ae. aegypti were allowed to develop. We then assessed the effect of Rb- and Cs-enriched water on fitness, survival and bioaccumulation in both adult females and their eggs. Results indicated that Cs had adverse effects on Ae. aegypti, even at low concentrations, whereas Rb at low concentrations had no measured effects on exposed individuals and accumulated at detectable levels in adult females. The method described here relies on passive uptake of Rb during immature stages, which has the benefit of avoiding handling or manipulation of the dispersive adults, which enables purer measurement of movement. Moreover, we demonstrated that Rb was transferred efficiently from the marked females to their eggs. To our knowledge, Rb is the only marker used for mosquitoes that has been shown to transfer vertically from females to eggs. The application of Rb rather than more traditional markers may therefore increase the quality (no impact on released individuals) and quantity (both adults and eggs are marked) of data collected during MR studies. The method we propose here can be used in combination with other markers, such as stable isotopes, in order to maximize the information collected during MR experiments

Interdependence between sexual debut and church attendance in Italy

The influence of religion on an individual’s life-course in general – and on sexual behaviour in particular – has long been recognised by social scientists, although few studies have explored the reciprocal causal interdependence between religiosity and sexual debut, mainly in an overwhelmingly Catholic European context. In this paper, we study the dynamic bi-directional effect between first coital experience and discontinuance of church attendance among a representative sample of Italian students. Both effects work, contrasting the results of other authors regarding the USA, where only the effect of religion on sex has been detected. The present results do not change when the two processes are considered simultaneously and unobserved heterogeneity is taken into account. Some possible explanations are discussed.college students, Italy, religion, sexual debut, unobserved heterogeneity

Understanding factors contributing to risky sexual activity in the study abroad environment

Researchers suggest that study abroad students may be an un-identified high risk group for risky sexual activity. The goal of this study was to determine whether factors predictive of risky sexual activity at home (sexual sensation seeking, alcohol and sex expectancies, alcohol consumption and previous risky behaviors) may also influence such behavior while abroad. Data was collected longitudinally with a pre and post survey that assessed the above constructs. Twenty-four study abroad students completed the pre survey and six completed the post survey. Two Independent samples t-tests were conducted to clarify differences between gender and students who completed the pre-survey compared to the pre-and post-survey. Three additional Independent samples t-test were conducted to clarify differences between risky and non-risky students. Results suggest that there is no difference on the variables of interest between gender, overall risk and casual partner risk compared by non-risky students. Significant differences emerged between students who completed the pre-survey compared to the pre-and post survey and students who engaged in risky condom use compared to non-risky students. Limitations and directions for future research are discussed

Translating Tolkien. The thin line between translation and misrepresentation. An italian case-study

This article deals with the translation of the work of J.R.R. Tolkien. It investigates the possibility that translation may represent a potential weapon, in the hands of tolkien\u27s patronizing critics, to transform from the inside , id est through misrepresentation, what could not be incorporated or normalized “from the outside”, i.e. by traditional criticism. The basis for these considerations is a case-study related to the Italian context. Recently (2019), the previous Italian translation of The Lord of the Rings was withdrawn from the market by the publisher, in order to replace it with a different one. The way in which this operation was conducted and its results have caused severe perplexity in many Italian readers of Tolkien
