Social Consequence, Stakeholder Influence, and Resource Needs for Marcellus Shale Communities
The process of natural gas recovery by horizontal drilling and hydraulic fracturing, known as fracking, is a major scientific advance in unconventional energy development. Attention has largely been focused on its economic advantages and potential negative environmental repercussions, while less consideration given to its social dimensions. The purpose of this study was to explore the social consequences of fracking for communities in the Appalachian Basin\u27s Marcellus shale. Research questions focused on the role of stakeholders and the resource needs of localities in shaping public policy. This study was guided by the tenets of the Boomtown theory along with key issues in fracking research such as environmental impacts, water resources, public health and safety, economics, and ethical concerns. An embedded case study research design was employed, using a purposive sample of 8 economic and policy subject matter experts from the 3 most prolific drilling counties in Pennsylvania. Data were collected by semi-structured interviews and were analyzed using open and axial coding with cross-case comparison. Results suggested that positive economic social consequences of fracking involved sustainability in providing generational and employment stability. Negative consequences, such as traffic, damaged infrastructure, and housing shortages, were temporary and manageable. Logistical and demographic information were valuable resources for community leadership, and stakeholders favored autonomy in decision making. The implications for social change include informing policy makers how to prepare the local workforce to be adaptable, establish sufficient infrastructure to support change, and educate communities to leverage opportunity in advance of new industry
The 9/11 victim compensation fund : a case study
The 9/11 Victim Compensation Fund was the largest victim compensation fund in U.S. history, disseminating more than $7B federal tax monies directly to survivors, victims and their respective families following the terrorist attacks of that day. This represented an unprecedented effort on the part of the U.S. government to fully fund terrorism victim compensation within a no-fault framework intended, first and foremost, to protect the airline industry from potential economic ruin. But in so doing, the Fund compromised legal, ethical, economic and sociological principles on which victim compensation had been based since the inception of government. This interdisciplinary exploratory case study of the 9/11 Victim Compensation Fund analyzes the Fund from a holistic perspective and evaluates the complex forces contributing to global victim compensation theory. The 9/11 Victim Compensation Fund should not serve as a model for governmental assistance but instead highlights the need for universal consistency of nomenclature and intention. Globally, government\u27s role in victim compensation has become normative, but a lack of equivalency across national boundaries undermines the social solidarity required by such initiatives. Toward this end, the U.S. government, working in concert with the EU and CoE must strive to develop a single-minded model for this victim class
Research Is a Partner in Forward Focused Time
The complexities of modern society and the dynamic forces of progress necessitate that professionals in every discipline be forward-focused, which is believed to come from gaining higher education. This is becoming standard within the fire and emergency services professions and is commonly a factor regarding upward mobility. With that in mind, the U.S. Fire Administration/National Fire Academy (NFA) developed the Fire and Emergency Services Higher Education (FESHE) recognition certificate

Neurodevelopmental and Epilepsy Phenotypes in Individuals With Missense Variants in the Voltage-Sensing and Pore Domains of KCNH5
Background and Objectives KCNH5 encodes the voltage-gated potassium channel EAG2/Kv10.2. We aimed to delineate the neurodevelopmental and epilepsy phenotypic spectrum associated with de novo KCNH5 variants.Methods We screened 893 individuals with developmental and epileptic encephalopathies for KCNH5 variants using targeted or exome sequencing. Additional individuals with KCNH5 variants were identified through an international collaboration. Clinical history, EEG, and imaging data were analyzed; seizure types and epilepsy syndromes were classified. We included 3 previously published individuals including additional phenotypic details.Results We report a cohort of 17 patients, including 9 with a recurrent de novo missense variant p.Arg327His, 4 with a recurrent missense variant p.Arg333His, and 4 additional novel missense variants. All variants were located in or near the functionally critical voltage-sensing or pore domains, absent in the general population, and classified as pathogenic or likely pathogenic using the American College of Medical Genetics and Genomics criteria. All individuals presented with epilepsy with a median seizure onset at 6 months. They had a wide range of seizure types, including focal and generalized seizures. Cognitive outcomes ranged from normal intellect to profound impairment. Individuals with the recurrent p.Arg333His variant had a self-limited drug-responsive focal or generalized epilepsy and normal intellect, whereas the recurrent p.Arg327His variant was associated with infantile-onset DEE. Two individuals with variants in the pore domain were more severely affected, with a neonatal-onset movement disorder, early-infantile DEE, profound disability, and childhood death.Discussion We describe a cohort of 17 individuals with pathogenic or likely pathogenic missense variants in the voltage-sensing and pore domains of Kv10.2, including 14 previously unreported individuals. We present evidence for a putative emerging genotype-phenotype correlation with a spectrum of epilepsy and cognitive outcomes. Overall, we expand the role of EAG proteins in human disease and establish KCNH5 as implicated in a spectrum of neurodevelopmental disorders and epilepsy.</p
Bi-allelic Loss-of-Function CACNA1B Mutations in Progressive Epilepsy-Dyskinesia.
The occurrence of non-epileptic hyperkinetic movements in the context of developmental epileptic encephalopathies is an increasingly recognized phenomenon. Identification of causative mutations provides an important insight into common pathogenic mechanisms that cause both seizures and abnormal motor control. We report bi-allelic loss-of-function CACNA1B variants in six children from three unrelated families whose affected members present with a complex and progressive neurological syndrome. All affected individuals presented with epileptic encephalopathy, severe neurodevelopmental delay (often with regression), and a hyperkinetic movement disorder. Additional neurological features included postnatal microcephaly and hypotonia. Five children died in childhood or adolescence (mean age of death: 9 years), mainly as a result of secondary respiratory complications. CACNA1B encodes the pore-forming subunit of the pre-synaptic neuronal voltage-gated calcium channel Cav2.2/N-type, crucial for SNARE-mediated neurotransmission, particularly in the early postnatal period. Bi-allelic loss-of-function variants in CACNA1B are predicted to cause disruption of Ca2+ influx, leading to impaired synaptic neurotransmission. The resultant effect on neuronal function is likely to be important in the development of involuntary movements and epilepsy. Overall, our findings provide further evidence for the key role of Cav2.2 in normal human neurodevelopment.MAK is funded by an NIHR Research Professorship and receives funding from the Wellcome Trust, Great Ormond Street Children's Hospital Charity, and Rosetrees Trust.

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
