Parenting in America: Outlook, Worries, Aspirations Are Strongly Linked to Financial Situation

Family life is changing. Two-parent households are on the decline in the United States as divorce, remarriage and cohabitation are on the rise. And families are smaller now, both due to the growth of single-parent households and the drop in fertility. Not only are Americans having fewer children, but the circumstances surrounding parenthood have changed. While in the early 1960s babies typically arrived within a marriage, today fully four-in-ten births occur to women who are single or living with a non-marital partner. At the same time that family structures have transformed, so has the role of mothers in the workplace – and in the home. As more moms have entered the labor force, more have become breadwinners – in many cases, primary breadwinners – in their families.As a result of these changes, there is no longer one dominant family form in the U.S. Parents today are raising their children against a backdrop of increasingly diverse and, for many, constantly evolving family forms. By contrast, in 1960, the height of the post-World War II baby boom, there was one dominant family form. At that time 73% of all children were living in a family with two married parents in their first marriage. By 1980, 61% of children were living in this type of family, and today less than half (46%) are. The declining share of children living in what is often deemed a "traditional" family has been largely supplanted by the rising shares of children living with single or cohabiting parents.Not only has the diversity in family living arrangements increased since the early 1960s, but so has the fluidity of the family. Non-marital cohabitation and divorce, along with the prevalence of remarriage and (non-marital) recoupling in the U.S., make for family structures that in many cases continue to evolve throughout a child's life. While in the past a child born to a married couple – as most children were – was very likely to grow up in a home with those two parents, this is much less common today, as a child's living arrangement changes with each adjustment in the relationship status of their parents. For example, one study found that over a three-year period, about three-in-ten (31%) children younger than 6 had experienced a major change in their family or household structure, in the form of parental divorce, separation, marriage, cohabitation or death

A Statistical Analysis of Death Rates in Italy for the Years 2015–2020 and a Comparison with the Casualties Reported from the COVID-19 Pandemic

We analyze the data about casualties in Italy in the period 01/01/2015 to 30/09/2020 released by the Italian National Institute of Statistics (ISTAT). Aim of this article is the description of a statistically robust methodology to extract quantitative values for the seasonal excesses of deaths featured by the data, accompanying them with correct estimates of the relative uncertainties. We will describe the advantages of the method adopted with respect to others listed in literature. The data exhibit a clear sinusoidal behavior, whose fit allows for a robust subtraction of the baseline trend of casualties in Italy, with a surplus of mortality in correspondence to the flu epidemics in winter and to the hottest periods in summer. The overall quality of the fit to the data turns out to be very good, an indication of the validity of the chosen model. We discuss the trend of casualties in Italy by different classes of ages and for the different genders. We finally compare the data-subtracted casualties, as reported by ISTAT, with those reported by the Italian Department for Civil Protection (DPC) relative to the deaths directly attributed to COVID-19, and we point out the differences in the two samples, collected under different assumptions

Faith/less? Market integrity and the enforcement of Australia’s continuous disclosure provisions

The very idea of ‘continuous disclosure’ and all it carries with it – corporate transparency, equal access to information, a level playing field amongst market participants for trade in an entity’s securities – is of serious value to the effective and efficient functioning of the Australian market for capital. The extent to which the structures supporting faith in this ideal are actually effecting it in reality is therefore an important issue for consideration. To what extent then do enforcement efforts surrounding the regime justify any faith placed in the integrity of the market by lay investors? Put differently, should investors feel confident that the immediate release of material information relevant to their trading decisions is well policed, with the effect that there are likely to be few deviations from this ideal standard, and that the market can be trusted to provide information necessary to maintain a level playing field? An important question on par with this preliminary is whether there is anything that might be learnt from enforcement activity of various kinds to improve the type of corporate reporting which has been subjected to it. Inquiry into these questions will serve to temper corporate and investor expectations as to just what the practical requirements and limits of a system of continuous disclosure might be. The purpose of this dissertation is to offer a deeper understanding of the enforcement of Australia’s continuous disclosure regime, from high profile court cases and the imposition of administrative sanctions to ‘everyday’ enforcement activity through ASX price queries and aware letters, and offer an analysis of what might be learnt from them with a view to improving the daily function of continuous disclosure in Australian markets. Such an understanding might at the very least ensure the development of a realistic set of expectations around this interesting, if unusual, set of rules

3D Printed Architectured Silicones with Autonomic Self-healing and Creep-resistant Behavior

Self-healing silicones that are able to restore the functionalities and extend the lifetime of soft devices hold great potential in many applications. However, currently available silicones need to be triggered to self-heal or suffer from creep-induced irreversible deformation during use. Here, we design and print silicone objects that are programmed at the molecular and architecture levels to achieve self-healing at room temperature while simultaneously resisting creep. At the molecular scale, dioxaborolanes moieties are incorporated into silicones to synthesize self-healing vitrimers, whereas conventional covalent bonds are exploited to make creep-resistant elastomers. When combined into architectured printed parts at a coarser length scale, layered materials exhibit fast healing at room temperature without compromising the elastic recovery obtained from covalent polymer networks. A patient-specific vascular phantom is printed to demonstrate the potential of architectured silicones in creating damage-resilient functional devices using molecularly designed elastomer materials

Prevalence of Incidental Pancreatic Cysts on 3 Tesla Magnetic Resonance

ObjectivesTo ascertain the prevalence of pancreatic cysts detected incidentally on 3-Tesla magnetic resonance imaging (MRI) of the abdomen and correlate this prevalence with patient age and gender; assess the number, location, and size of these lesions, as well as features suspicious for malignancy; and determine the prevalence of incidentally detected dilatation of the main pancreatic duct (MPD).MethodsRetrospective analysis of 2,678 reports of patients who underwent abdominal MRI between January 2012 and June 2013. Patients with a known history of pancreatic conditions or surgery were excluded, and the remaining 2,583 reports were examined for the presence of pancreatic cysts, which was then correlated with patient age and gender. We also assessed whether cysts were solitary or multiple, as well as their location within the pancreatic parenchyma, size, and features suspicious for malignancy. Finally, we calculated the prevalence of incidental MPD dilatation, defined as MPD diameter >= 2.5 mm.ResultsPancreatic cysts were detected incidentally in 9.3% of patients (239/2,583). the prevalence of pancreatic cysts increased significantly with age (p= 5 mm in size; 12.1% were suspicious for malignancy. An estimated 2.7% of subjects had a dilated MPD.Universidade Federal de São Paulo UNIFESP, Escola Paulista Med, Dept Imaging Diag, São Paulo, SP, BrazilUniversidade Federal de São Paulo UNIFESP, Escola Paulista Med, Dept Imaging Diag, São Paulo, SP, BrazilWeb of Scienc

Service composition in stochastic settings

With the growth of the Internet-of-Things and online Web services, more services with more capabilities are available to us. The ability to generate new, more useful services from existing ones has been the focus of much research for over a decade. The goal is, given a specification of the behavior of the target service, to build a controller, known as an orchestrator, that uses existing services to satisfy the requirements of the target service. The model of services and requirements used in most work is that of a finite state machine. This implies that the specification can either be satisfied or not, with no middle ground. This is a major drawback, since often an exact solution cannot be obtained. In this paper we study a simple stochastic model for service composition: we annotate the tar- get service with probabilities describing the likelihood of requesting each action in a state, and rewards for being able to execute actions. We show how to solve the resulting problem by solving a certain Markov Decision Process (MDP) derived from the service and requirement specifications. The solution to this MDP induces an orchestrator that coincides with the exact solution if a composition exists. Otherwise it provides an approximate solution that maximizes the expected sum of values of user requests that can be serviced. The model studied although simple shades light on composition in stochastic settings and indeed we discuss several possible extensions
