The Effects of Social Welfare Development on Poor Single Mothers in the United States: What Is to Be Done?
Examining the Barriers to the Continuing Education of Early Childhood Teacher Assistants
The Improving Head Start for School Readiness Act of 2007 required teacher assistants (TAs) to obtain their child development associate (CDA) credential by September of 2015. TAs who had not obtained their CDA within the required timeframe were either demoted or terminated from their positions. However, with the increase of working parents, the need for quality early childhood education has risen. In this project study, the barriers TAs confront in regards to their decision to continue their schooling to obtain a CDA credential were examined, as were the factors that deterred or prevented them from enrolling in or completing a higher education program. The purpose of the study was to inform the development of a plan outlining how childcare administration can mentor and encourage TAs in the completion of their CDA program. Knowles\u27s theory of adult learning and Kolb\u27s experiential learning theory provided the theoretical basis and framework for this qualitative case study. Cluster random selection was used to identify 9 participants who were interviewed using a semistructured process. Interview responses were recorded, transcribed, and broken down into 6 themes. Findings showed that 7 out of 9 participants experienced barriers to continuing their education, and 8 of the 9 partipants expressed a desire to participate in a mentoring program. Raising the educational requirements and completion rate of TAs positively affects social change through increased quality of instruction, improved teaching strategies, and enhanced and developmentally appropriate support provided to young children
Increased reticulocytosis during infancy is associated with increased hospitalizations in sickle cell anemia patients during the first three years of life
Objective
Among older children with sickle cell anemia, leukocyte counts, hemoglobin, and reticulocytosis have previously been suggested as disease severity markers. Here we explored whether these blood parameters may be useful to predict early childhood disease severity when tested in early infancy, defined as postnatal ages 60â180 days. Study Design
Data from fifty-nine subjects who were followed at Childrenâs National Medical Centerâs Sickle Cell Program for at least three years was retrospectively analyzed. Comparisons were made between white blood cell counts, hemoglobin and reticulocyte levels measured at ages 60â180 days and the clinical course of sickle cell anemia during infancy and childhood. Results
A majority of subjects had demonstrable anemia with increased reticulocytosis. Only increased absolute reticulocyte levels during early infancy were associated with a significant increase in hospitalization during the first three years of life. Higher absolute reticulocyte counts were also associated with a markedly shorter time to first hospitalizations and a four-fold higher cumulative frequency of clinical manifestations over the first three years of life. No significant increase in white blood cell counts was identified among the infant subjects. Conclusions
These data suggest that during early infancy, increased reticulocytosis among asymptomatic SCA subjects is associated with increased severity of disease in childhood
Regulatory Considerations in the Design and Manufacturing of Implantable 3DâPrinted Medical Devices
Threeâdimensional (3D) printing, or additive manufacturing, technology has rapidly penetrated the medical device industry over the past several years, and innovative groups have harnessed it to create devices with unique composition, structure, and customizability. These distinctive capabilities afforded by 3D printing have introduced new regulatory challenges. The customizability of 3Dâprinted devices introduces new complexities when drafting a design control model for FDA consideration of market approval. The customizability and unique build processes of 3Dâprinted medical devices pose unique challenges in meeting regulatory standards related to the manufacturing quality assurance. Consistent material powder properties and optimal printing parameters such as build orientation and laser power must be addressed and communicated to the FDA to ensure a quality build. Postprinting considerations unique to 3Dâprinted devices, such as cleaning, finishing and sterilization are also discussed. In this manuscript we illustrate how such regulatory hurdles can be navigated by discussing our experience with our group's 3Dâprinted bioresorbable implantable device.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/115990/1/cts12315.pd
Drawing and Knowledge Construction in Archaeology: The Aide MĂ©moire Project
The Aide MĂ©moire Project conducted a survey and a series of observational studies in field recording and artifact illustration to understand 1) the perception of digital and by-hand drawing in archaeology, 2) how drawing contributes to the creation of mental models that allow archaeologists to understand archaeological remains and artifacts, and 3) what impact digital drawing has on the creation of these mental models. Our toolkit includes the NASA Task Load Index to assess and compare the mental load while drawing digitally or by-hand. We conclude that there are significant pedagogical, academic, and professional implications to consider when removing or replacing by-hand drawing with digital recording in archaeological methodology

âOur Relationship? Itâs the Odd Mucky Weekend, Not a One Night Standâ: Journalists and aid agencies in the UK, and the current challenges to sourcing in humanitarian disasters
In humanitarian crises, the sources that journalists employ have always helped determine which stories achieve a high media profile, as well as play a part in framing the story. In particular, aid agencies acted as powerful gatekeepers to disaster zones, providing flights, transport, fixers and translators to journalistsâand more recently, text, images and resources for the social web. Questions have been raised around transparency and objectivity in such reporting as a result. This paper draws on 40 semi-structured qualitative interviews with UK national journalists (broadcast, print and online) and aid agencies belonging to the UK's Disasters Emergency Committee. As a result, this paper builds on journalism studies looking at boundary (re)negotiations in journalism and the source-media relationship to show the current patterns in what has been described as a âmutually exploitativeâ relationship. It compares and contrasts what assistance journalists say they accept from aid agencies and what aid agencies report. It examines how both sides are often unwilling to acknowledge the close association. It will also look at how the increasing professionalisation of NGO operations including the employment of former journalists and producing their own content may be affecting the power dynamics. Finally, it asks whether the slow emergence of scandals means this relationship has not only affected stories that are covered but those that are not

The TRENDS High-contrast Imaging Survey. I. Three Benchmark M Dwarfs Orbiting Solar-type Stars
We present initial results from a new high-contrast imaging program dedicated to stars that exhibit long-term Doppler radial velocity accelerations (or "trends"). The goal of the TRENDS (TaRgetting bENchmark-objects with Doppler Spectroscopy) imaging survey is to directly detect and study the companions responsible for accelerating their host star. In this first paper of the series, we report the discovery of low-mass stellar companions orbiting HD 53665, HD 68017, and HD 71881 using NIRC2 adaptive optics (AO) observations at Keck. Follow-up imaging demonstrates association through common proper motion. These comoving companions have red colors with estimated spectral types of K7-M0, M5, and M3-M4, respectively. We determine a firm lower limit to their mass from Doppler and astrometric measurements. In the near future, it will be possible to construct three-dimensional orbits and calculate the dynamical mass of HD 68017 B and possibly HD 71881 B. We already detect astrometric orbital motion of HD 68017 B, which has a projected separation of 13.0 AU. Each companion is amenable to AO-assisted direct spectroscopy. Further, each companion orbits a solar-type star, making it possible to infer metallicity and age from the primary. Such benchmark objects are essential for testing theoretical models of cool dwarf atmospheres
The key role of examining the placenta in establishing a probable cause for stillbirth
INTRODUCTION : Autopsy is regarded as the âgold standardâ to determine probable causes of stillbirths. However, autopsy is expensive and not readily available in low- and middle-income countries. Therefore, we assessed how the clinical cause of death is modified by adding placental histology and autopsy findings.
METHOD : Data from the Safe Passage Study was used where 7060 pregnant women were followed prospectively. Following a stillbirth, each case was discussed and classified at weekly perinatal mortality meetings. This classification was later adapted to the WHO ICD PM system. Clinical information was presented first, and a possible cause of death decided upon and noted. The placental histology was then presented and, again, a possible cause of death, using the placental and clinical information, was decided upon and noted, followed by autopsy information. Diagnoses were then compared to determine how often the additional information changed the initial clinical findings.
RESULTS : Clinical information, placental histology, and autopsy results were available in 47 stillbirths. There were major amendments from the clinical only diagnoses when placental histology was added. Forty cases were classified as due to M1: complications of placenta, cord, and membranes, when placental histology was added compared to 7 cases with clinical classification only, and M5: No maternal condition identified decreased from 30 cases to 3 cases. Autopsy findings confirmed the clinical and placental histology findings.
DISCUSSION : Clinical information together with examination of the placenta revealed sufficient information to diagnose the most probable cause of death in 40 of 47 cases of stillbirth (85%).The National Institute on Alcohol Abuse and Alcoholism, Eunice Kennedy Shriver National Institute of Child Health and Human Development, and National Institute on Deafness and Other Communication Disorders.http://www.elsevier.com/locate/placentahj2023Obstetrics and Gynaecolog

Combining geographic information systems and ethnography to better understand and plan ocean space use
Agencies in the US with oversight for marine renewable energy development have idealistically sought space where this new use might proceed unhindered by other uses. Despite experiential evidence of spatial overlap among existing ocean uses, a lack of documentation makes the identification of potential space-use conflicts, communication among existing and potential ocean users, and the design of mitigation exceedingly challenging. We conducted a study in select communities along the US Atlantic and Pacific coasts to gather and document available spatial information on existing use through a compilation and organization of geographic information system (GIS) data. Stakeholder group meetings were used to vet the collected spatial data and ethnographic interviews were conducted to gather additional knowledge and cultural perspectives. Results show extensive overlap of existing ocean space uses and provide a visualization of the social and cultural landscape of the ocean that managers can use to determine which stakeholders to engage when considering the development of alternative uses. Marine space use is dynamic and multi-dimensional and there are important linkages within and across fisheries and other uses, communities and interests, as well as across the land-sea interface. The research reported here demonstrates the feasibility and necessity of (1) integrating ethnographic and geospatial data collection and analysis; (2) engaging stakeholders throughout the process; and (3) recognizing the unique qualities of each geographic location and user group to support sound decision-making.Keywords: Ethnography, Marine Spatial Planning, GIS, Participatory Mapping, P-GIS, Ocean Space Us
