Why we should be more optimistic about the competency of American voters

The traditional view that voters have stable beliefs about what government should do and what policies they prefer has become unstuck, with many commentators and academics now doubting that voters approach politics with any consistent preferences. In new research, Melanie Freeze and Jacob M. Montgomery reject this view, arguing that public opinion is generally stable across many issues, and that the public is getting better at connecting their preferences to their ideology. By removing random and time-dependent errors from election and survey data, they find that preferences on a range of issues such as abortion policy and gay marriage have been relatively stable and have also become more closely correlated with party identification over the past two decades

Attitudes of Marriage and Divorce in Adult Children of Gray Divorce

Divorce over the age of 50 years is called gray divorce and has been steadily on the rise. Past studies have shown the impact divorce can have on children regarding attitudes toward marriage and divorce, but research has not investigated the attitudes of adult children whose parents divorce late in life. An intrinsic, single case study was done using eight participants who were adult children of gray divorce. Semi-structured interviews were completed, guided by the principles of social learning theory. Data were analyzed into codes, categories, and then into seven overarching themes using categorical aggregation. Six themes regarding the attitudes toward marriage and divorce are discussed along with one additional theme that was discovered. Themes include a desire to marry, attitudes of marriage and divorce were impacted by their parents’ experiences, that divorce is not ideal but is sometimes best, a determination to make their marriages work and not repeat their parents’ mistakes, and gladness that their parents divorced. The participants were impacted in terms of feeling a sense of marital impermanence, a determination to succeed in their relationships, and an understanding and acceptance of divorce in unhealthy and unhappy circumstances. Learning the impact that late-life divorce has on adult children of divorce can assist therapists, educators, human service professionals, social programs, as well as parents and children affected by gray divorce

Bicuspid Aortic Valve: a Review with Recommendations for Genetic Counseling

Bicuspid aortic valve (BAV) is the most common congenital heart defect and falls in the spectrum of left-sided heart defects, also known as left ventricular outflow tract obstructive (LVOTO) defects. BAV is often identified in otherwise healthy, asymptomatic individuals, but it is associated with serious long term health risks including progressive aortic valve disease (stenosis or regurgitation) and thoracic aortic aneurysm and dissection. BAV and other LVOTO defects have high heritability. Although recommendations for cardiac screening of BAV in at-risk relatives exist, there are no standard guidelines for providing genetic counseling to patients and families with BAV. This review describes current knowledge of BAV and associated aortopathy and provides guidance to genetic counselors involved in the care of patients and families with these malformations. The heritability of BAV and recommendations for screening are highlighted. While this review focuses specifically on BAV, the principles are applicable to counseling needs for other LVOTO defects

Application of Random Walk Model for Timing Recovery in Modern Mobile SATCOM Systems

In a modern mobile satellite communication (SATCOM) system, a ground terminal receiver receives a radio frequency signal that is demodulated to generate a baseband digital signal waveform containing a self-clocking bit stream of digital data. The received baseband digital signal waveform is recovered and tracked using a timing recovery loop (TRL). The traditional TRLs use early-and-late gates, digital transition tracking, filter-and-square, and delay-and-multiply functions. In bit timing detection, the bit stream is self-clocking and the timing differential dithers about correct bit timing in the TRLs. For mobile satellite communication environments, the traditional TRLs drop lock when the loop signal-to-noise ratio (SNR) is smaller than a threshold value or the residual Doppler frequency is larger than the operating loop bandwidth. After dropping lock, the traditional TRLs experience long hang up time due to the need to reacquire the timing pulses. Recently, random walk filters (RWF) have been adapted to improve the bit clock locking stability and are applied to recover bit timing information of a digital data stream. This chapter describes random walk model for timing jitter and discusses how RWF solution can address the timing recovery challenges in mobile satellite communication environments

On the generalized Davenport constant and the Noether number

Known results on the generalized Davenport constant related to zero-sum sequences over a finite abelian group are extended to the generalized Noether number related to the rings of polynomial invariants of an arbitrary finite group. An improved general upper bound is given on the degrees of polynomial invariants of a non-cyclic finite group which cut out the zero vector.Comment: 14 page

System-of-Systems Enterprise CONOPS Assessment Decision Support Tools

This chapter discusses the implementation of System-of-Systems Enterprise Architecture (SOSEA) CONOPS assessment framework and models in Matlab, and presents preliminary results concerning SOSEA resiliency in the presence of a notional Radio Frequency Interference (RFI) scenario. The chapter provides an overview of the SOSEA CONOPS Assessment Framework, and discusses related SOS Resiliency Models including Resilient Assessment Index Against RFI (RAI-RFI), Spectrum Resiliency Assessment Index (SRAI), and Resilient Capacity (RC)

Dissecting the molecular organization of the translocon-associated protein complex

In eukaryotic cells, one-third of all proteins must be transported across or inserted into the endoplasmic reticulum (ER) membrane by the ER protein translocon. The translocon-associated protein (TRAP) complex is an integral component of the translocon, assisting the Sec61 protein-conducting channel by regulating signal sequence and transmembrane helix insertion in a substrate-dependent manner. Here we use cryo-electron tomography (CET) to study the structure of the native translocon in evolutionarily divergent organisms and disease-linked TRAP mutant fibroblasts from human patients. The structural differences detected by subtomogram analysis form a basis for dissecting the molecular organization of the TRAP complex. We assign positions to the four TRAP subunits within the complex, providing insights into their individual functions. The revealed molecular architecture of a central translocon component advances our understanding of membrane protein biogenesis and sheds light on the role of TRAP in human congenital disorders of glycosylation

Provision of rehabilitation for congenital conditions.

Considerable progress has been made in saving the lives of children younger than 5 years. Nevertheless, these advances have failed to help all children thrive, particularly children with disabilities. We describe the increasing prevalence of disability among children and adolescents. We evaluate the current situation regarding children with disabilities and rehabilitation in the context of health systems, particularly those in low- and middle-income countries. Within the newborn health agenda, congenital anomalies often require early intervention and rehabilitation. We provide Argentina as an example of a country where rehabilitation for congenital anomalies is integrated into the health system. We argue that congenital anomalies that require rehabilitation have the potential to strengthen rehabilitation systems and policies by: strengthening coordination between primary care and rehabilitation; identifying and understanding pathways that allow families to engage with services; providing human resources for rehabilitation; and building systems and resources that support assistive technology and rehabilitation. We propose ways for countries to prioritize and integrate early identification, referral and care for children with congenital anomalies to strengthen health systems for all. We identify opportunities to expand policy and planning and to design service delivery and workforce strategies through World Health Organization guidelines and frameworks for rehabilitation. We argue that the global health community must act to ensure that rehabilitation services to support functioning from birth are well established, accepted and integrated within health systems, and that disability is prioritized within child health. These steps would strengthen health systems, ensure functioning from birth and make rehabilitation accessible to all
