Ideal Family Size and Fertility in Egypt: An Overview of Recent Trends

Egypt is already the most populous Arab country in the world with 93 million citizens in 2016 which may grow to about 120 million by 2030 if the same level of fertility continues. This paper aims to offer an overview of the evolution over time of the ideal number of children in Egypt, assessing previous researches and giving a particular emphasis on most recent data on such topic. In a context of raising fertility, whose causes are still unknown, we test the persistence of a high ideal number of children among younger cohorts

Old age and inequalities in Egypt. The role of intergenerational relationships and transfers within the family

The paper aims at analysing the condition of the elderly in Egypt, a country where ageing is a rising trend. Our focus is on the role intergenerational ties and transfers within the family have in alleviating poverty situations of aged people. We analyse old people living arrangements in order to underline the spread of vulnerability among them. In a social and economic context where old people are vulnerable to poverty, we intend to investigate the importance of economic and non-economic flows towards the elderly. We use individual data from Egypt Labour Market Survey 1998 and 2006 that inform about demographic characteristics of individuals, households, housing conditions and non-work sources of income

Adolescent childbearing experiences in Kenya: geographical and socioeconomic determinants

Sub-Saharan Africa has one of the highest level of teenage pregnancies in the world. Some studies on this topic highlight the presence of unmet reproductive health needs of adolescent in different regions. Improving maternal health has been established as a key development priority among the Millennium Development Goals, and upgrading reproductive and maternal health is usually associated with the eradication of inequality and poverty and with the presence of health care programs and services devoted to girls’ education. We attempt to investigate the geographical and socioeconomic determinants of both teenage pregnancies and maternal health behaviours among adolescent women in Kenya. We ascertain the influence of the availability of health care facilities mainly oriented to the specific needs of reproductive health. Main data are represented by 2003 Kenyan Demographic and Health Survey. In addition, the DHS data set collects Global Positioning System locators for each of the primary sampling units included in the samples that enable a deep geographical analysis. We perform a multivariate multilevel analysis to estimate the influence that individual, household, and community-level factors have on the risk of adolescent childbearing. Additionally, a spatial component allows for the presence and proximity of maternal health services. We expect that the availability of reproductive health facilities acts together with levels of socio-economic development, individual and household characteristics and community fertility norms, in influencing individual reproductive behavior at very young ages.Kenya, gravidanze adolescenziali, salute materna, strutture sanitarie, modelli multilivello Kenya, teenage pregnancy, maternal health, health facilities, multilevel modelling, millennium development goals

A time-series analysis

(ProQuest: ... denotes formulae omitted.)1. PremiseDuring the last four decades of the 20th century, the average total fertility rate (TFR) has continuously dropped in Europe, as it generally has in Organization for Economic Cooperation and Development (OECD) countries. The aggregate trend covers considerable differences across Europe, with the main differences appearing between northern and southern European countries (Eurostat 2012).During the same period, important changes have also occurred in the labour market arrangements of both men and women, with changes in individuals' and couples' economic conditions. Whereas by the 1980s the fall in fertility was coupled with a rise in female employment, since the late 1980s the fall has been accompanied by a rise in unemployment, particularly among women.Explaining the determinants of such a fall in fertility and the links with changes in the labour market statuses of both men and women has become a major topic over the last years (D'Addio and Mira d'Ercole 2005; Kreyenfeld 2010).The rise in unemployment for women and men in southern and central European countries that occurred during the 1990s has been proposed as an explanation for the more pronounced decrease in the TFR in these countries, as in other countries with low female labour force participation rates (Ahn and Mira 2002; Adsera 2005; Engelhardt and Prskawetz 2004). This evidence highlights the need to further examine the role of unemployment in fertility behaviour.This paper seeks to describe the connections between fertility and unemployment in Italy from a gender-based and geographic perspective. Italian workers have experienced a rising trend of unemployment - with gender and regional differences - since the mid-nineties, resulting in a feeling of uncertainty about the future. We are in agreement with the hypothesis that macro-level economic conditions are likely to be related to fertility (Brewster and Rindfuss 2000): in particular, economic uncertainty can induce a short-term reduction in fertility that is presumably due to the postponement of decisions to have an (additional) child until the economy recovers.We utilised time series of aggregate data on fertility and unemployment during the interval 1995-2012, which includes the period of economic downturn that began at the end of 2007.We began from the hypothesis that the connection between unemployment and fertility differs among the various Italian regions, and we used a regression dynamic model to evaluate whether changes in fertility in different Italian geographic areas are more related to changes in male or female unemployment, as well as the strength of the link. Moreover, we paid particular attention to specific temporal links between the two series in different geographical areas.The structure of the paper is as follows:- Discussion of the literature and previous research on the relationship between fertility and unemployment of both men and women. We utilised aggregate data, but we also referred to studies of individual-level data to understand how the issue has been addressed by different approaches;- Discussion of these relationships in Italy within the European context;- Methodological approach and analysis of aggregate trends of fertility and unemployment in Italy by gender and geographic area; and- Discussion of the results.2. Unemployment and fertility: A complex relationshipA modern discussion on fertility in developed countries began in the 1960s and focused on the importance of socio-economic factors at the community or country level, 4 the incompatibility between work and family, increasing female education, and the roles of women in different contexts related to specific welfare policies (Oppenheimer 1988; McDonald 2006; Pison 2009).The decrease in fertility rates in the 1960s and 1970s in most industrialised economies was correlated with an increase in female employment (Adsera 2004).

Photoionization of furan from the ground and excited electronic states

Here we present a comparative computational study of the photoionization of furan from the ground and the two lowest-lying excited electronic states. The study aims to assess the quality of the computational methods currently employed for treating bound and continuum states in photoionization. For the ionization from the ground electronic state, we show that the Dyson orbital approach combined with an accurate solution of the continuum one particle wave functions in a multicenter B-spline basis, at the density functional theory (DFT) level, provides cross sections and asymmetry parameters in excellent agreement with experimental data. On the contrary, when the Dyson orbitals approach is combined with the Coulomb and orthogonalized Coulomb treatments of the continuum, the results are qualitatively different. In excited electronic states, three electronic structure methods, TDDFT, ADC(2), and CASSCF, have been used for the computation of the Dyson orbitals, while the continuum was treated at the B-spline/DFT level. We show that photoionization observables are sensitive probes of the nature of the excited states as well as of the quality of excited state wave functions. This paves the way for applications in more complex situations such as time resolved photoionization spectroscopy

Smart Approach for the Design of Highly Selective Aptamer-Based Biosensors

Aptamers are chemically synthesized single-stranded DNA or RNA oligonucleotides widely used nowadays in sensors and nanoscale devices as highly sensitive biorecognition elements. With proper design, aptamers are able to bind to a specific target molecule with high selectivity. To date, the systematic evolution of ligands by exponential enrichment (SELEX) process is employed to isolate aptamers. Nevertheless, this method requires complex and time-consuming procedures. In silico methods comprising machine learning models have been recently proposed to reduce the time and cost of aptamer design. In this work, we present a new in silico approach allowing the generation of highly sensitive and selective RNA aptamers towards a specific target, here represented by ammonium dissolved in water. By using machine learning and bioinformatics tools, a rational design of aptamers is demonstrated. This "smart" SELEX method is experimentally proved by choosing the best five aptamer candidates obtained from the design process and applying them as functional elements in an electrochemical sensor to detect, as the target molecule, ammonium at different concentrations. We observed that the use of five different aptamers leads to a significant difference in the sensor's response. This can be explained by considering the aptamers' conformational change due to their interaction with the target molecule. We studied these conformational changes using a molecular dynamics simulation and suggested a possible explanation of the experimental observations. Finally, electrochemical measurements exposing the same sensors to different molecules were used to confirm the high selectivity of the designed aptamers. The proposed in silico SELEX approach can potentially reduce the cost and the time needed to identify the aptamers and potentially be applied to any target molecule

Roadmap on printable electronic materials for next-generation sensors

The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities to advance the sustainability and quality of our lives—e.g., via smart homes, smart cities, smart healthcare, smart logistics, Industry 4.0, and precision agriculture. The realization of the full potential of these applications critically depends on the availability of easy-to-make, low-cost sensor technologies. Sensors based on printable electronic materials offer the ideal platform: they can be fabricated through simple methods (e.g., printing and coating) and are compatible with high-throughput roll-to-roll processing. Moreover, printable electronic materials often allow the fabrication of sensors on flexible/stretchable/biodegradable substrates, thereby enabling the deployment of sensors in unconventional settings. Fulfilling the promise of printable electronic materials for sensing will require materials and device innovations to enhance their ability to transduce external stimuli—light, ionizing radiation, pressure, strain, force, temperature, gas, vapours, humidity, and other chemical and biological analytes. This Roadmap brings together the viewpoints of experts in various printable sensing materials—and devices thereof—to provide insights into the status and outlook of the field. Alongside recent materials and device innovations, the roadmap discusses the key outstanding challenges pertaining to each printable sensing technology. Finally, the Roadmap points to promising directions to overcome these challenges and thus enable ubiquitous sensing for a sustainable, ‘intelligent’ world
