    Abstract: Porous asphalt concrete (PAC) has an open-graded aggregate mixture to yield high air voids; PAC is mainly applied to the surface drainage layer on high-speed trafficked highway pavements. The objective of the study was to investigate the effect of binder types on the engineering properties and field performance of PAC mixtures. Three binder types were selected for a 19-mm nominal maximum aggregate size gradation: conventional asphalt AR-80, polymer-modified asphalt, and high-viscosity asphalt. A series of laboratory tests were conducted to evaluate the engineering properties of the PAC mixture, including permeability, resistance to draindown, resistance to disintegration, resistance to rutting, and resistance to indirect traction. A 3-km in-service test road was constructed to monitor the performance of PAC pavements using these three binders. Polymer-modified binder was shown to minimize abrasion loss and enhance the durability of the PAC mixture. Test results indicated that the use of polymer-modified binder, instead of unmodified binder, reduced rutting and raveling. When the mixture contained high-viscosity binder, it showed the best performance in the field. Field measurements indicated improved drainage as a result of replacement of the conventional asphalt AR-80 binder with the polymer-modified and high-viscosity binders. PAC pavement surfaces provided good frictional characteristics once the asphalt binder film was worn from the aggregate.

    Abstract: Child support enforcement (CSE) has experienced dramatic changes in the last decade; however, it is not clear whether child support staff is fully aware of the development. Using data from the New Jersey child support training program (n = 530), this article aims to evaluate the professional knowledge of child support staff. The results show that participants answered 55% of the questions on CSE correctly in the pretraining assessment. After the training, the participants answered 77% of all questions correctly. The findings reveal an urgent need for training for child support staff in a rapidly changing profession.

    Abstract: Using the first 3 waves of the Fragile Families and Child Wellbeing Study, this article examines the prevalence and factors of domestic violence among unmarried mothers with a young child. The findings indicate that the prevalence of domestic violence for mothers increased substantially in the first 3 years after the child's birth. Findings from regression analyses show that mothers who lived with the father, either as a wife or cohabiting partner, had significantly lower odds of domestic violence in the study measures than mothers who did not live with the father. However, the odds of domestic violence were not significantly different between married and cohabiting mothers. Policy implications are discussed.

    Abstract: This purpose of this paper is to evaluate the effect of rubber deposits on pavement friction characteristics on the basis of macroscopic and microscopic measurements. Runway pavement sections at the Kaohsiung (Taiwan) International Airport were chosen for field and laboratory testing over a 16-month period. In the first step of the field testing, the monthly variation in friction was established by using the Saab surface friction tester (SFT) and British pendulum testing. In the second step, macro-texture measurements were made by the grease patch method. The last step of field testing was to take samples of rubber deposits for laboratory analyses by optical microscope and scanning electron microscopy. Results showed that rubber deposits had strong effects on runway surface friction. An aircraft landing appeared to result in an increase in the thickness of rubber deposits by approximately 0.05 μm. The microstructure of rubber deposits was shown to be accumulated by the directional distribution of multiple layers of polymer scale. The friction value measured in the backward direction was higher than that measured in the forward direction. The rate of decrease in the SFT friction value was found to be about 0.05 for an increase in rubber thickness of 0.1 mm.

    Abstract: Using the 1991-1998 Survey of Family Income and Expenditure, we analyzed the determinants of college attendance rates and educational expenditure among families with children in Taiwan, paying particular attention to the effects of family structure and family income. The findings indicate that higher family income is consistently associated with higher college attendance rates and spending on education. Children in single-parent families have lower college attendance rates than children in two-parent families. Furthermore, single-parent families spend less on education. When family income is taken into account, single-mother families are not significantly different from two-parent families on the outcome variables. Single-father families, however, are estimated to have significantly lower college attendance rates and educational expenditure after controlling for family income. These results suggest that improving the economic security of single-parent families will increase their children's attainment in single-mother families but will not eliminate the attainment gap between children in single-father and two-parent families.

    Effect of Surface Characteristics on Bonding Properties of Bituminous Tack Coat
    SAGE Publications ; 2010

    Abstract: The evaluation of the influence of surface characteristics on the bonding properties at the interlayer is important to understand better how multi-layered pavements behave under traffic conditions. Three double-layered systems were prepared with dense, porous asphalt concrete and stone mastic asphalt mixtures. The direct shear test was used to measure the bond properties provided by tack coat, whereas the surface characteristics were measured by traditional techniques. Variables included surface type, curing time, curing temperature, emulsion type, and residual application rate. For a given value of applied normal stress, the interface between the dense-graded asphalt mixtures resulted in higher peak shear strength than that between the open- and gap-graded mixtures. An increase in mean texture depth and film thickness led to a decrease in the peak shear strength and the reaction tangential modulus. The surface characteristics were shown to play a key role in interlayer bonding. Curing time was an important factor, indicating that paving could be performed right after the emulsion was broken. Increasing the residual application rate increased shear strength up to a point, then shear strength decreased gradually. The use of tack coat increased the interface bond strength, and an optimum residual application rate existed, at which the shear resistance reached a maximum value. The bonding properties at elevated temperatures were more associated with the surface characteristics than at lower temperatures.

    Abstract: Using 4 waves of a longitudinal dataset, this study tested whether maternal mental health and parenting at Year 3 mediate the effects of domestic violence at Year 1 on preschool children's internalizing or externalizing behavior problems at Year 5. After controlling for preexisting child effects and parenting stress, structural equation models revealed that maternal mental health mediated the effects of domestic violence for children's externalizing behavior problems. Parenting, specifically spanking, mediated those effects for both behavior problems of children. Domestic violence had direct effects on both types of behavior problems of children. These findings highlight the long-term effects of domestic violence on preschool children and the need for early intervention and prevention efforts for the children in violent families.

    Abstract: Children who grow up with exposure to intimate partner violence (IPV) experience disproportionately greater cognitive, psychological, and emotional impairments when compared to their peers. Increasingly, research has provided evidence of the long-lasting effects of IPV exposure throughout the life course. This study uses data from four waves (baseline and Years 1, 3, and 15) of the Fragile Families and Child Wellbeing Study (FFCWS) to examine how IPV exposure affects adolescents’ dating behavior and relationship quality at Year 15. Results indicate that those adolescents with exposure to physical violence at Years 1 and 3 were more likely to be in dating relationships at Year 15 than those without (effect size = 0.40), and for adolescents who were in a dating relationship at Year 15, IPV exposure, particularly exposure to physical violence, significantly reduced relationship quality (effect size = −0.24). These findings call for early screening of IPV exposure among mothers, children, and adolescents, as well as interventions to support victimized mothers and promote healthy adolescent relationships.

    Intimate Partner Violence During Pregnancy: Effects of Maternal Depression Symptoms and Parenting on Teen Depression Symptoms
    SAGE Publications ; 2022

    Abstract: Past studies have indicated that mothers who are victims of intimate partner violence (IPV) have a greater risk of developing depression symptoms. Furthermore, existing literature provides evidence that children’s mental health can be affected by their mother’s mental health well past infancy and early childhood. Given this, children of IPV victims are particularly at risk of developing depression symptoms. Guided by trauma theory, the ecobiodevelopmental (EBD) framework, and social learning theory, this study investigates the long-term relationship between maternal IPV victimization during pregnancy and teen depression symptoms. This study utilizes longitudinal data from the Fragile Families and Child Wellbeing Study to examine the relationship between IPV during pregnancy and maternal depression symptoms at early childhood, as well as the mechanism by which maternal depression symptoms affect child depression symptoms in the adolescent stage of development. The findings indicate that mothers who were victims of IPV during pregnancy were more likely to have depression symptoms when children turned 3 and that maternal depression symptoms could directly predict children’s depression symptoms at age 15. Meanwhile, maternal depression symptoms could indirectly increase adolescent depression symptoms via physical punishment at age 5 and bullying victimization at age 9. While extensive evidence has shown that IPV during pregnancy has detrimental effects on mothers and children, our study adds to the literature that such detriments can last as long as a decade. Given that depression symptoms can be detrimental to later development, the findings call for universal and comprehensive IPV screening tools and swift service referrals for pregnant women who are experiencing IPV. At the same time, trauma-informed parenting education for women, along with school- and community-based interventions for children, may also mitigate these harmful associations.

    In: Ear, Nose & Throat Journal, SAGE Publications
    Abstract: Accidental swallowing of fish bone is one of the most common emergencies in the otolaryngology department. The impacted fish bones are usually found in the palatine tonsil, base of the tongue, valleculae, pyriform sinus, and esophagus, which can be successfully removed after a thorough examination. However, in some cases, the fish bone may penetrate into the neck soft tissue and migrate to extraluminal organs, causing infection, abscess formation, or rupture of vessels. In such cases, prompt recognition and immediate removal of the impacted fish bone are necessary. Herein, we report a rare case of a 60-year-old woman who had accidently swallowed a fish bone 10 days prior to visiting the outpatient department. The fiberoptic scope and head and neck computed tomography scans were obtained from the outpatient department. The fish bone was found to migrate from the upper esophagus to the left thyroid gland. First, a rigid esophageal endoscopy was performed in the operating room, but no obvious fish bone was noted over the esophagus. Finally, the fish bone was removed via exploratory cervicotomy with left-sided total lobectomy of the thyroid. The patient recovered after the operation, and there were no further complications during the 3 years of follow-up.
