Hemopericardium following cerebral hemorrhage. Report of an autopsy case.

The simultaneous occurrence of cerebral hemorrhage and hemopericardium due to the rupture of a dissecting aneurysm has not been previously reported. We describe an autopsy case of a 45-year-old man with hypertension who died suddenly following both of these conditions. He had been treated for hypertension; the finding of arteriolar nephrosclerosis supported the existence of the disease. Because rupture of the aorta invariably causes a marked fall in blood pressure, the occurrence of cerebral hemorrhage following hemopericardium is highly unlikely. Thus, we presume that rupture of the aorta occurred after the cerebral hemorrhage.     

HLA DQ alpha typing of forensic specimens by amplification restriction fragment polymorphism (ARFP) analysis.

The alleles present at the HLA DQ alpha locus may be typed by either allele specific oligonucleotide (ASO) probing or by restriction mapping, referred to here as amplification restriction fragment polymorphism (ARFP) analysis. ASO typing relies upon hybridization principles, whereas ARFP typing relies upon restriction site analysis. Dot-blot ASO typings which are of doubtful interpretation may be directly checked by ARFP analysis. Aliquots of the PCR products amplified using the commercial Amplitype HLA DQ alpha system are digested with suitable restriction endonucleases. Electrophoresis, blotting and detection of biotin-labelled restriction fragments provides a sensitive and robust typing method suited to forensic analysis.     

Norms versus Action: Why Voters Fail to Sanction Malfeasance in Brazil

We show that Brazilian voters strongly sanction malfeasant mayors when presented with hypothetical scenarios but take no action when given the same information about their own mayor. Partnering with the State Accounts Court of Pernambuco, we conducted a field experiment during the 2016 municipal elections in which the treatment group received information about official wrongdoing by their mayor. The treatment has no effect on self‐reported voting behavior after the election, yet when informing about malfeasance in the context of a vignette experiment, we are able to replicate the strong negative effect found in prior studies. We argue that voters' behavior in the abstract reflects the comparatively strong norm against corruption in Brazil. Yet on Election Day, their behavior is constrained by factors such as attitudes toward local political dynasties and the greater salience of more pressing concerns like employment and health services.

Cost‐Effectiveness of Early Childhood Interventions to Enhance Preschool: Evidence from a Randomized Experiment in Head Start Centers Enrolling Historically Underserved Populations

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.     

Governing Unconventional Oil and Gas Extraction: The Case of Pennsylvania

Over the past decade, directional drilling and hydraulic fracturing enabled an unconventional oil and gas extraction (UOGE) boom in many regions of the United States, including parts of Pennsylvania. This revolution has created serious concerns about the capability of existing institutions to govern important societal outcomes associated with UOGE. We present a conceptual framework for assessing key societal outcomes influenced by UOGE governance. In applying this framework to Pennsylvania, we discern certain institutional strengths that have allowed the Commonwealth to reap appreciable short‐term economic growth from rich resource endowments. We also find, however, that several institutional weaknesses have allowed costs externalized to the environment, public health, and community integrity to offset some proportion of those economic benefits. Likewise, we find that governance of UOGE in Pennsylvania has contributed to a bifurcated sociopolitical landscape wherein adversarial coalitions dispute the legitimacy of the industry and its governance.     

Designing for equitable civic engagement: Participatory design and discourse in contested spaces

A common theme of research on participatory democracy and citizen engagement centres on the need for empirical studies that conduct a deep exploration of the nuances and complexities of these processes. This article offers a distinct response to this need through an examination of two ethnographic case studies of a participatory budgeting process in a multilingual, highly diverse community in which Spanish-speaking Latino immigrants were involved. By analyzing participants discourse from the case studies, the findings highlight the risks and rewards of reframing participatory processes as design decisions rather than static procedures.
