Sibling Violence: The Missing Piece in Family Violence Policy

Social work has played an integral role in the conceptualization and implementation of policy aimed at prevention and intervention of various forms of family violence. Seminal federal policies to address child abuse and neglect (Child Abuse Prevention and Treatment Act), elder abuse (Elder Justice and Older Americans Acts), and intimate partner violence (Violence Against Women and Family Violence Prevention and Services Acts) all focus on specific types of violence in the family. To date, however, there are no federal policies specifically addressing physical and/or emotional sibling violence (Perkins, Coles, & O’Connor, 2017; Perkins & O’Connor, 2016). This article examines the exclusion of policy addressing physical and emotional sibling violence considering other family violence policies. Along with prevalence, consequences, and associative factors connected to sibling violence, definitional issues that impede the creation of policy to address this form of family violence are highlighted. Children as a marginalized population, deserving the attention of social workers through policy advocacy will be discussed as well as psychoeducation and interprofessional collaboration that may facilitate the creation of policies aimed at addressing this form of family violence

The Impact of COVID-19 on Family Violence in Immigrant Communities in the United States

The COVID-19 pandemic has threatening implications for all individuals; and has been particularly unsettling for immigrants. Given their unique positionality in the U.S., the intersectional discussion about the impact of this pandemic on immigrants and issues of family violence is salient. The position of some groups of immigrant women is even more precarious due to the increased dependency on their spouse/partner for emotional, economic and immigration-related reasons. While immigrants have been on the frontlines as responders for COVID-19, there are limited policies that provide them with healthcare, employment guarantee, or benefits. Further, the immigration restrictions created by the U.S. Government have worsened the position of immigrants. All these stressors create unprecedented challenges for immigrants. Therefore, it is vital to delve into the family dynamics, unique challenges, and potential solutions that can provide support to immigrant families. This commentary highlights the atypical challenges of immigrants in relation to the pandemic and how these challenges may impact the incidence of family violence. Through our discussion, we hope to encourage social work scholars, practitioners, and policy advocates to support and advocate for immigrants; especially, during the new normal under the COVID-19 pandemic

Research Knowledge of Advanced Standing and Traditional Students: Implications for BSW Education

The advanced standing model of social work education, which affords graduate credit to qualified BSW students who pursue their MSW, has not been without issue or controversy, including questions of potential differences in performance on various educational outcomes. Specifically related to research curriculum, the importance of which is often not wholly embraced by students, this article reports the results of a secondary data analysis comparing research knowledge among advanced standing and traditional MSW students as well as among the various undergraduate majors (i.e., BSW, psychology, and sociology). Results suggest that research knowledge is similar and low across student subgroups. Important differences in research knowledge were found among student groups based on undergraduate major, with BSW undergraduates without advanced standing, on average, scoring lower than any other group. Implications for BSW research curriculum are considere

Examples of Embedded Defects (in Particle Physics and Condensed Matter)

We present a series of examples designed to clarify the formalism of the companion paper `Embedded Vortices'. After summarising this formalism in a prescriptive sense, we run through several examples: firstly, deriving the embedded defect spectrum for Weinberg-Salam theory, then discussing several examples designed to illustrate facets of the formalism. We then calculate the embedded defect spectrum for three physical Grand Unified Theories and conclude with a discussion of vortices formed in the superfluid $^3$He-A phase transition.Comment: final corrections. latex fil

Mitochondrial Rejuvenation After Induced Pluripotency

Background: As stem cells of the early embryo mature and differentiate into all tissues, the mitochondrial complement undergoes dramatic functional improvement. Mitochondrial activity is low to minimize generation of DNA-damaging reactive oxygen species during pre-implantation development and increases following implantation and differentiation to meet higher metabolic demands. It has recently been reported that when the stem cell type known as induced pluripotent stem cells (IPSCs) are re-differentiated for several weeks in vitro, the mitochondrial complement progressively re-acquires properties approximating input fibroblasts, suggesting that despite the observation that IPSC conversion ‘‘resets’ ’ some parameters of cellular aging such as telomere length, it may have little impact on other age-affected cellular systems such as mitochondria in IPSC-derived cells. Methodology/Principal Findings: We have examined the properties of mitochondria in two fibroblast lines, corresponding IPSCs, and fibroblasts re-derived from IPSCs using biochemical methods and electron microscopy, and found a dramatic improvement in the quality and function of the mitochondrial complement of the re-derived fibroblasts compared to input fibroblasts. This observation likely stems from two aspects of our experimental design: 1) that the input cell lines used were of advanced cellular age and contained an inefficient mitochondrial complement, and 2) the re-derived fibroblasts were produced using an extensive differentiation regimen that may more closely mimic the degree of growth and maturatio

Generation of Large-Scale Vorticity in a Homogeneous Turbulence with a Mean Velocity Shear

An effect of a mean velocity shear on a turbulence and on the effective force which is determined by the gradient of Reynolds stresses is studied. Generation of a mean vorticity in a homogeneous incompressible turbulent flow with an imposed mean velocity shear due to an excitation of a large-scale instability is found. The instability is caused by a combined effect of the large-scale shear motions (''skew-induced" deflection of equilibrium mean vorticity) and ''Reynolds stress-induced" generation of perturbations of mean vorticity. Spatial characteristics, such as the minimum size of the growing perturbations and the size of perturbations with the maximum growth rate, are determined. This instability and the dynamics of the mean vorticity are associated with the Prandtl's turbulent secondary flows. This instability is similar to the mean-field magnetic dynamo instability. Astrophysical applications of the obtained results are discussed.Comment: 8 pages, 3 figures, REVTEX4, submitted to Phys. Rev.

Nuclear transparency from quasielastic A(e,e'p) reactions uo to Q^2=8.1 (GeV/c)^2

The quasielastic (e,e$^\prime$p) reaction was studied on targets of deuterium, carbon, and iron up to a value of momentum transfer $Q^2$ of 8.1 (GeV/c)$^2$. A nuclear transparency was determined by comparing the data to calculations in the Plane-Wave Impulse Approximation. The dependence of the nuclear transparency on $Q^2$ and the mass number $A$ was investigated in a search for the onset of the Color Transparency phenomenon. We find no evidence for the onset of Color Transparency within our range of $Q^2$. A fit to the world's nuclear transparency data reflects the energy dependence of the free proton-nucleon cross section.Comment: 11 pages, 6 figure

A high-throughput de novo sequencing approach for shotgun proteomics using high-resolution tandem mass spectrometry

<p>Abstract</p> <p>Background</p> <p>High-resolution tandem mass spectra can now be readily acquired with hybrid instruments, such as LTQ-Orbitrap and LTQ-FT, in high-throughput shotgun proteomics workflows. The improved spectral quality enables more accurate <it>de novo </it>sequencing for identification of post-translational modifications and amino acid polymorphisms.</p> <p>Results</p> <p>In this study, a new <it>de novo </it>sequencing algorithm, called Vonode, has been developed specifically for analysis of such high-resolution tandem mass spectra. To fully exploit the high mass accuracy of these spectra, a unique scoring system is proposed to evaluate sequence tags based primarily on mass accuracy information of fragment ions. Consensus sequence tags were inferred for 11,422 spectra with an average peptide length of 5.5 residues from a total of 40,297 input spectra acquired in a 24-hour proteomics measurement of <it>Rhodopseudomonas palustris</it>. The accuracy of inferred consensus sequence tags was 84%. According to our comparison, the performance of Vonode was shown to be superior to the PepNovo v2.0 algorithm, in terms of the number of <it>de novo </it>sequenced spectra and the sequencing accuracy.</p> <p>Conclusions</p> <p>Here, we improved <it>de novo </it>sequencing performance by developing a new algorithm specifically for high-resolution tandem mass spectral data.
