The confessions of Edward Day : a novel
New York in the 1970s: rents were cheap, love was free, and the explosion of theater venues off and off-off Broadway afforded aspiring actors the opportunity to work for nothing. After Edward Day joins his fellow actors for a summer weekend on the Jersey shore, his life is never the same.

Economic Situation, Financial Strain and Child Wellbeing in Stepfamilies and Single-Parent Families in Germany
AimThe aim of this paper is to identify predictors of financial strain and to clarify the importance of family type and income, as well as the effects of financial strain, on child wellbeing. We consider family structure by looking at nuclear families, stepfamilies and single-parent families. We also examine family complexity by considering the status of a child, e.g., a common child in a nuclear family, a stepchild, or common child in a stepfamily.MethodsApplying the Family Stress Model (FSM; Conger et al. 1990), we address the following issues: what family types are more financially burdened and rate themselves as being financially strained? How is child behavior affected by financial strain, and which type of child is affected most?ResultsThe data that we use are from the survey “Growing up in Germany”: AID:A II wave (2013–2015); our sample consists of 12,561 children, and the method that we apply is ordered probit models.ConclusionsOur results clearly suggest that single-parent families and stepfamilies are more vulnerable to be below the poverty threshold. Regarding our second set of analyses, the results suggest that stepchildren and children in single-parent families are more at risk for problem behavior than are children in nuclear families. Moreover, both groups experience financial strain.

Motivational Versus Metabolic Effects of Carbohydrates on Self-Control
Self-control is critical for achievement and well-being. However, people's capacity for self-control is limited and becomes depleted through use. One prominent explanation for this depletion posits that self-control consumes energy through carbohydrate metabolization, which further suggests that ingesting carbohydrates improves self-control. Some evidence has supported this energy model, but because of its broad implications for efforts to improve self-control, we reevaluated the role of carbohydrates in self-control processes. In four experiments, we found that (a) exerting self-control did not increase carbohydrate metabolization, as assessed with highly precise measurements of blood glucose levels under carefully standardized conditions; (b) rinsing one's mouth with, but not ingesting, carbohydrate solutions immediately bolstered self-control; and (c) carbohydrate rinsing did not increase blood glucose. These findings challenge metabolic explanations for the role of carbohydrates in self-control depletion; we therefore propose an alternative motivational model for these and other previously observed effects of carbohydrates on self-control.

Using the Embedded Element Finite-Element Method to Simulate Impact of Dyneema® Plates
The embedded finite-element technique provides a unique approach for modeling of fiber-reinforced composites. Meshing fibers as distinct bundles represented by truss elements embedded in a matrix material mesh allow for the assignment of more specific material properties for each component rather than homogenization of all the properties. This approach also allows for different damage and failure properties to be assigned the matrix and fiber materials which could provide new insight into the failure of the composite material, but also presents unique challenges in the implementation of the finite-element method. Here, we present a proof-of-concept model of a plate of Dyneema
®
under impact conditions using the embedded element method to represent the cross-ply fibers grouped into truss elements. We show that the embedded truss elements provide an easy way to implement the orthotropic material properties and transmit stress waves through the plate in a way that is consistent with images from experimental data.

The Impact of Neurofibromatosis Type 1 on the Health and Wellbeing of Australian Adults
The complications of neurofibromatosis type 1 (NF1) are widespread, unpredictable and variable and each person’s experience of this disorder is unique. However, few studies have addressed the impact of NF1 from an individual’s perspective. This qualitative study aims to identify the ways in which NF1 impacts upon affected Australian adults. Sixty adults with NF1, with a range of disease severity and visibility participated in a semi-structured interview about the ways in which NF1 impacted upon their life and health. Data were analyzed using grounded theory methodology. Results indicated that NF1 impacts upon affected adults in five major ways: 1) cosmetic burden of disease 2) learning difficulties 3) concerns about the risk of passing NF1 to offspring 4) uncertain disease progression, and 5) pain. Participants identified the aspects of NF1 that bothered them the most, creating a hierarchy of NF1 concerns within the cohort. Importantly, mildly affected adults shared many of the same concerns as those more severely affected. This study enhances our current understanding of the impact of NF1 in adulthood, and augments existing recommendations for the care of these patients.

An energy-based study of the embedded element method for explicit dynamics
The embedded finite element technique provides a unique approach for modeling of fiber-reinforced composites. Meshing fibers as distinct bundles represented by truss elements embedded in a matrix material mesh allows for the assignment of more specific material properties for each component rather than homogenization of all of the properties. However, the implementations of the embedded element technique available in commercial software do not replace the material of the matrix elements with the material of the embedded elements. This causes a redundancy in the volume calculation of the overlapping meshes leading to artificially increased stiffness and mass. This paper investigates the consequences in the energy calculations of an explicit dynamic model due to this redundancy. A method for the correction of the edundancy within a finite element code is suggested which removes extra energy and is shown to be effective at correcting the energy calculations for large amounts of redundant volume.
