Detecting and Reporting Child Abuse: A Function of the Human Service Delivery System

This paper reports the results of a regression analysis performed on 48, 499 reports of known or suspected child abuse submitted from 1974 through 1983 to the Colorado Department of Social Services Central Child Abuse Registry. Enrollments in human service programs, combined with events which precipitate enrollee use of services, and the presence of human service professionals and institutions are strongly related to the number of abuse cases reported

Digging deeper: quality of patient-provider communication across Hispanic subgroups

<p>Abstract</p> <p>Background</p> <p>Recent research suggests that ethnic subgroup designation plays an important role in health-related disparities among Hispanics. Our objective was to examine the influence of Hispanics' self-reported ethnic subgroup designation on perceptions of their health care providers' communication behaviors.</p> <p>Methods</p> <p>Cross-sectional analysis of the 2005 Medical Expenditure Panel Survey (MEPS). Participants included non-institutionalized Hispanics (n = 5197; US population estimate = 27,070,906), aged ≥18 years, reporting visiting a health care provider within the past 12 months. Six (n = 6) items were used to capture respondents' perceptions of their health care providers' communication behaviors.</p> <p>Results</p> <p>After controlling for socio-demographic covariates, compared to Other Hispanics (reference group), very few differences in perceptions of health care providers communication emerged across ethnic subgroups. Puerto Ricans were more likely to report that their health care provider "always" showed respect for what they had to say (OR = 2.16, 95% CI 1.16-4.03). Both Puerto Ricans (OR = 2.28, 95% CI 1.06-4.92) and Mexicans (OR = 1.88, 95% CI 1.02-3.46) were more likely to indicate that their health care provider "always" spent enough time with them as compared to Other Hispanics.</p> <p>Conclusions</p> <p>We observed very few differences among Hispanics respondents in their perceived quality of interactions with health care providers as a function of their ethnic subgroup designation. While our findings somewhat contradict previous research, they do suggest that other underlying factors may influence the quality of perceived interactions with health care providers.</p

The magnitude of educational disadvantage amongst indigenous minority groups in Australia.

Indigenous groups are amongst the most disadvantaged minority groups in the developed world. This paper examines the educational disadvantage of indigenous Australians by assessing academic performance at a relatively early age. We find that, by the age of 10, indigenous Australians are substantially behind non-indigenous Australians in academic achievement. Their relative performance deteriorates further over the next 2 years. School and locality do not appear to be important determinants of the indigenous to non-indigenous achievement gap. However, geographic remoteness, indigenous ethnicity and language use at home have a marked influence on educational achievement. A current focus of Australian indigenous policy is to increase school resources. Our results suggest that this will not eliminate indigenous educational disadvantage on its own

Law and Policy Resource Guide: A Survey of Eminent Domain Law in Texas and the Nation

Eminent Domain is the power of the government or quasi-government entities to take private or public property interests through condemnation. Eminent Domain has been a significant issue since 1879 when, in the case of Boom Company v. Patterson, the Supreme Court first acknowledged that the power of eminent domain may be delegated by state legislatures to agencies and non-governmental entities. Thus, the era of legal takings began. Though an important legal dispute then, more recently eminent domain has blossomed into an enduring contentious social and political problem throughout the United States. The Fifth Amendment to the United States Constitution states, “nor shall private property be taken for public use, without just compensation.” Thus, in the wake of the now infamous decision in Kelo v. City of New London, where the Court upheld the taking of private property for purely economic benefit as a “public use,” the requirement of “just compensation” stands as the primary defender of constitutionally protected liberty under the federal constitution. In response to Kelo, many state legislatures passed a variety of eminent domain reforms specifically tailoring what qualifies as a public use and how just compensation should be calculated. Texas landowners recognize that the state’s population is growing at a rapid pace. There is an increasing need for more land and resources such as energy and transportation. But, private property rights are equally important, especially in Texas, and must be protected as well. Eminent domain and the condemnation process is not a willing buyer and willing seller transition; it is a legally forced sale. Therefore, it is necessary to consider further improvements to the laws that govern the use of eminent domain so Texas landowners can have more assurance that this process is fair and respectful of their private property rights when they are forced to relinquish their land. This report compiles statutes and information from the other forty-nine states to illustrate how they address key eminent domain issues. Further, this report endeavors to provide a neutral third voice in Texas to strike a more appropriate balance between individual’s property rights and the need for increased economic development. This report breaks down eminent domain into seven major topics that, in addition to Texas, seemed to be similar in many of the other states. These categories are: (1) Awarding of Attorneys’ Fee; (2) Compensation and Valuation; (3) Procedure Prior to Suit; (4) Condemnation Procedure; (5) What Cannot be Condemned; (6) Public Use & Authority to Condemn; and (7) Abandonment. In analyzing these seven categories, this report does not seek to advance a particular interest but only to provide information on how Texas law differs from other states. This report lays out trends seen across other states that are either similar or dissimilar to Texas, and additionally, discusses interesting and unique laws employed by other states that may be of interest to Texas policy makers. Our research found three dominant categories which tend to be major issues across the country: (1) the awarding of attorneys’ fees; (2) the valuation and measurement of just compensation; and (3) procedure prior to suit

Pulsar kicks from a dark-matter sterile neutrino

We show that a sterile neutrino with mass in the 1-20 keV range and a small mixing with the electron neutrino can simultaneously explain the origin of the pulsar motions and the dark matter in the universe. An asymmetric neutrino emission from a hot nascent neutron star can be the explanation of the observed pulsar velocities. In addition to the pulsar kick mechanism based on resonant neutrino transitions, we point out a new possibility: an asymmetric off-resonant emission of sterile neutrinos. The two cases correspond to different values of the masses and mixing angles. In both cases we identify the ranges of parameters consistent with the pulsar kick, as well as cosmological constraints.Comment: 5 pages, 2 figures; final version; discussion and references adde

International medical graduates in family medicine in the United States of America: an exploration of professional characteristics and attitudes

BACKGROUND: The number of international medical graduates (IMGs) entering family medicine in the United States of America has steadily increased since 1997. Previous research has examined practice locations of these IMGs and their role in providing care to underserved populations. To our knowledge, research does not exist comparing professional profiles, credentials and attitudes among IMG and United States medical graduate (USMG) family physicians in the United States. The objective of this study is to determine, at the time when a large influx of IMGs into family medicine began, whether differences existed between USMG and IMG family physicians in regard to personal and professional characteristics and attitudes that may have implications for the health care system resulting from the increasing numbers of IMGs in family medicine in the United States. METHODS: This is a secondary data analysis of the 1996–1997 Community Tracking Study (CTS) Physician Survey comparing 2360 United States medical graduates and 366 international medical graduates who were nonfederal allopathic or osteopathic family physicians providing direct patient care for at least 20 hours per week. RESULTS: Compared to USMGs, IMGs were older (p < 0.001) and practised in smaller (p = 0.0072) and younger practices (p < 0.001). Significantly more IMGs practised in metropolitan areas versus rural areas (p = 0.0454). More IMG practices were open to all new Medicaid (p = 0.018) and Medicare (p = 0.0451) patients, and a greater percentage of their revenue was derived from these patients (p = 0.0020 and p = 0.0310). Fewer IMGs were board-certified (p < 0.001). More IMGs were dissatisfied with their overall careers (p = 0.0190). IMGs and USMGs did not differ in terms of self-rated ability to deliver high-quality care to their patients (p = 0.4626). For several of the clinical vignettes, IMGs were more likely to order tests, refer patients to specialists or require office visits than USMGs. CONCLUSION: There are significant differences between IMG and USMG family physicians' professional profiles and attitudes. These differences from 1997 merit further exploration and possible follow-up, given the increased proportion of family physicians who are IMGs in the United States

Traces of past activity in the Galactic Centre

The Milky Way centre hosts a supermassive Black Hole (BH) with a mass of ~4*10^6 M_Sun. Sgr A*, its electromagnetic counterpart, currently appears as an extremely weak source with a luminosity L~10^-9 L_Edd. The lowest known Eddington ratio BH. However, it was not always so; traces of "glorious" active periods can be found in the surrounding medium. We review here our current view of the X-ray emission from the Galactic Center (GC) and its environment, and the expected signatures (e.g. X-ray reflection) of a past flare. We discuss the history of Sgr A*'s past activity and its impact on the surrounding medium. The structure of the Central Molecular Zone (CMZ) has not changed significantly since the last active phase of Sgr A*. This relic torus provides us with the opportunity to image the structure of an AGN torus in exquisite detail.Comment: Invited refereed review.

Synaptic density in carriers of C9orf72 mutations: a [ 11 C]UCB‐J PET study

Abstract: Synaptic loss is an early and clinically relevant feature of many neurodegenerative diseases. Here we assess three adults at risk of frontotemporal dementia from C9orf72 mutation, using [11C]UCB‐J PET to quantify synaptic density in comparison with 19 healthy controls and one symptomatic patient with behavioural variant frontotemporal dementia. The three pre‐symptomatic C9orf72 carriers showed reduced synaptic density in the thalamus compared to controls, and there was an additional extensive synaptic loss in frontotemporal regions of the symptomatic patient. [11C]UCB‐J PET may facilitate early, pre‐symptomatic assessment, monitoring of disease progression and evaluation of new preventive treatment strategies for frontotemporal dementia

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant
