The National Dialogue on the Quadrennial Homeland Security Review

Six years after its creation, the Department of Homeland Security (DHS) undertook the first Quadrennial Homeland Security Review (QHSR) to inform the design and implementation of actions to ensure the safety of the United States and its citizens. This review, mandated by the Implementing the 9/11 Commission Recommendations Act of 2007, represents the first comprehensive examination of the homeland security strategy of the nation. The QHSR includes recommendations addressing the long-term strategy and priorities of the nation for homeland security and guidance on the programs, assets, capabilities, budget, policies, and authorities of the department.Rather than set policy internally and implement it in a top-down fashion, DHS undertook the QHSR in a new and innovative way by engaging tens of thousands of stakeholders and soliciting their ideas and comments at the outset of the process. Through a series of three-week-long, web-based discussions, stakeholders reviewed materials developed by DHS study groups, submitted and discussed their own ideas and priorities, and rated or "tagged" others' feedback to surface the most relevant ideas and important themes deserving further consideration.Key FindingsThe recommendations included: (1) DHS should enhance its capacity for coordinating stakeholder engagement and consultation efforts across its component agencies, (2) DHS and other agencies should create special procurement and contracting guidance for acquisitions that involve creating or hosting such web-based engagement platforms as the National Dialogue, and (3) DHS should begin future stakeholder engagements by crafting quantitative metrics or indicators to measure such outcomes as transparency, community-building, and capacity

Impact of Pilots’ Mental Health on Aviation Safety

In aviation, safety is the highest priority. Several recent aviation accidents and incidents have brought the mental health issue of the pilots to the forefront of aviation safety. To protect the safety of crew members and passengers, the Federal Aviation Administration (FAA) and other civil aviation authorities across the globe strictly regulate the status of pilots’ physical and mental health. The purpose of this paper is three-folded. First, it describes the significance of pilots’ mental health and its impact on aviation safety. Second, it explores the state of pilots’ current mental health and the causes and side-effects of mental health-related issues. Third, it reviews relevant regulations currently in place and summarizes available resources established by the FAA and civil aviation authorities to support pilots’ mental health. The paper concludes by providing useful recommendations beneficial for the pilots, regulatory agencies, and general public interested in getting a better understanding of mental health-related issues in high-stress professions

Qualitative evaluation of a deferred consent process in paediatric emergency research: a PREDICT study

Background: A challenge of conducting research in critically ill children is that the therapeutic window for the intervention may be too short to seek informed consent prior to enrolment. In specific circumstances, most international ethical guidelines allow for children to be enrolled in research with informed consent obtained later, termed deferred consent (DC) or retrospective consent. There is a paucity of data on the attitudes of parents to this method of enrolment in paediatric emergency research. Objectives: To explore the attitudes of parents to the concept of DC and to expand the knowledge of the limitations to informed consent and DC in these situations.MethodChildren presenting with uncomplicated febrile seizures or bronchiolitis were identified from three separate hospital emergency department databases. Parents were invited to participate in a semistructured telephone interview exploring themes of limitations of prospective informed consent, acceptability of the DC process and the most appropriate time to seek DC. Transcripts underwent inductive thematic analysis with intercoder agreement, using Nvivo 11 software. Results: A total of 39 interviews were conducted. Participants comprehended the limitations of informed consent under emergency circumstances and were generally supportive of DC. However, they frequently confused concepts of clinical care and research, and support for participation was commonly linked to their belief of personal benefit. Conclusion: Participants acknowledged the requirement for alternatives to prospective informed consent in emergency research, and were supportive of the concept of DC. Our results suggest that current research practice seems to align with community expectations.</jats:sec

The Sir Jimmy Savile Scandal: Child Sexual Abuse and Institutional Denial at the BBC

This study advances research on scandal through an empirical examination of one of the most extraordinary UK institutional child sexual abuse (CSA) scandals in the post-war period. Sir Jimmy Savile (1926–2011) was a BBC celebrity, showbiz friend of the establishment and philanthropist. In October 2012, one year after his death, an ITV documentary alleged that Savile was also a prolific sexual predator who for decades had exploited his BBC status to abuse teenage girls. As we demonstrate, this incendiary documentary triggered a news media feeding frenzy that in less than one week destroyed Savile’s reputation and thrust the BBC – the institution that made him a star – into a multi-faceted, globally reported CSA scandal. This study has four purposes. First, we propose a model of institutional CSA scandals that can account for critical transitions between key phases in the scandal process. Second, we apply this model to analyse the transition between the ‘latent’ and ‘activated’ phases of the Savile scandal. This transition corresponded with a dramatic transformation in the inferential structuring of Savile from ‘national treasure’, who had devoted decades to working with children, to ‘prolific sexual predator’, who spent decades abusing them. Third, we demonstrate how the BBC’s denial of responsibility for Savile’s sexual offending and its subsequent institutional cover-up triggered a ‘trial by media’ which in turn initiated the next phase in the scandal’s development – ‘amplification’. Finally, we consider the significance of our analysis of the Sir Jimmy Savile scandal for understanding the activation and development of scandals more generally

Subtidal macrozoobenthos communities from northern Chile during and post El Niño 1997–1998

Despite a large amount of climatic and oceanographic information dealing with the recurring climate phenomenon El Niño (EN) and its well known impact on diversity of marine benthic communities, most published data are rather descriptive and consequently our understanding of the underlying mechanisms and processes that drive community structure during EN are still very scarce. In this study, we address two questions on the effects of EN on macrozoobenthic communities: (1) how does EN affect species diversity of the communities in northern Chile? and (2) is EN a phenomenon that restarts community assembling processes by affecting species interactions in northern Chile? To answer these questions, we compared species diversity and co-occurrence patterns of soft-bottoms macrozoobenthos communities from the continental shelf off northern Chile during (March 1998) and after (September 1998) the strong EN event 1997–1998. The methods used varied from species diversity and species co-occurrence analyses to multivariate ordination methods. Our results indicate that EN positively affects diversity of macrozoobenthos communities in the study area, increasing the species richness and diversity and decreasing the species dominance. EN represents a strong disturbance that affects species interactions that rule the species assembling processes in shallow-water, sea-bottom environments

Metanephric adenoma of the kidney: an unusual diagnostic challenge

Although metanephric adenoma (MA) is a rare, benign neoplasm of epithelial cells, it is often difficult to distinguish this entity from other malignant neoplasms preoperatively. We report a case of a large renal mass for which preoperative diagnosis was indeterminate, with the differential diagnosis including Wilm’s tumor, MA, and papillary renal cell carcinoma (PRCC). Accurate postoperative differentiation of MA from PRCC is critical because adjuvant therapy is considered after surgical resection of PRCC tumors

Proportional Relations Between Systolic, Diastolic and Mean Pulmonary Artery Pressure are Explained by Vascular Properties

Recently, it was shown that proportional relationships exist between systolic, diastolic and mean pulmonary artery pressure (Psys, Pdia and Pmean) and that they are maintained under various conditions in both health and disease. An arterial-ventricular interaction model was used to study the contribution of model parameters to the ratios Psys/Pmean, and Pdia/Pmean. The heart was modeled by a time-varying elastance function, and the arterial system by a three-element windkessel model consisting of peripheral resistance, Rp, arterial compliance Ca, and pulmonary artery characteristic impedance Z0. Baseline model parameters were estimated in control subjects and compared to values estimated in patients with pulmonary hypertension. Results indicate that experimentally derived ratios Psys/Pmean and Pdia/Pmean could be accurately reproduced using our model (1.59 and 0.61 vs. 1.55 and 0.64, respectively). Sensitivity analysis showed that the (empirical) constancy of Psys/Pmean and Pdia/Pmean was primarily based on the inverse hyperbolic relation between total vascular resistance (RT; calculated as Rp + Z0) and Ca, (i.e. constant RTCa product). Of the cardiac parameters, only heart rate affected the pressure ratios, but the contribution was small. Therefore, we conclude that proportional relations between systolic, diastolic and mean pulmonary artery pressure result from the constancy of RTCa thus from pulmonary arterial properties, with only little influence of heart rate
