Authors: Spruance Lori A. , Harrison Caleb , Brady Patrick , Woolford Marti , LeBlanc Heidi 
Published: January 2018

ABSTRACTBACKGROUNDHaving breakfast is correlated with health and academic benefits; yet, many children do not consume breakfast, and participation in the federal School Breakfast Program remains low. The purpose of this study was to examine parent perceptions of school breakfast and identify relationships between those who consume breakfast at school and those who do not.METHODSA random sample of 100 schools, representing 29 school districts, across the state of Utah was selected to participate in the survey. Administrators were asked to distribute an online survey link to the parents of their school. Parents answered questions about their oldest kindergarten through 12th grade child. Qualitative and quantitative analyses were performed.RESULTSA total of 488 parents completed the survey. In a multilevel model, child grade level, participation in free and reduced‐price lunch, and perceive benefits to school breakfast were significantly related to eating breakfast at school. Some major themes from the qualitative analysis included no need for school breakfast, perception of regional values, and logistical issues.CONCLUSIONSParent perception of school meals is related to participation. This study identifies several areas of perception that could be address through parent education to increase school breakfast participation.

AbstractThrough activation of the ERK pathway, nicotine, in both normal MCF‐10A and low‐malignant breast cancer cells (MCF7), promotes increased motility and invasiveness. Melatonin antagonizes both these effects by inhibiting almost completely ERK phosphorylation. As melatonin has no effect on nonstimulated cells, it is likely that melatonin can counteract ERK activation only downstream of nicotine‐induced activation. This finding suggests that melatonin hampers ERK phosphorylation presumably by targeting a still unknown intermediate factor that connects nicotine stimulation to ERK phosphorylation. Furthermore, downstream of ERK activation, melatonin significantly reduces fascin and calpain activation while restoring normal vinculin levels. Melatonin also counteracts nicotine effects by reshaping the overall cytoskeleton architecture and abolishing invasive membrane protrusion. In addition, melatonin decreases nicotine‐dependent ROCK1/ROCK2 activation, thus further inhibiting cell contractility and motility. Melatonin actions are most likely attributable to ERK inhibition, although melatonin could display other ERK‐independent effects, namely through a direct modulation of additional molecular and structural factors, including coronin, cofilin, and cytoskeleton components.
London and urban culture in eighteenth‐century literature
Authors: O'Byrne Alison 
Published: January 2018

AbstractThis essay provides an overview of some of the key critical approaches to the literature of eighteenth‐century London over the last two decades, before going on to explore a series of examples of the figure of the new arrival in London from the literature of the period. The outsider or new arrival became, for eighteenth‐century writers, something to think with and offered an opportunity to examine London's sense of its own modernity, and interrogate the ways in which commerce might be reshaping social interactions in the city.

AbstractPlate tectonics and sediment processes control regional continental shelf topography. We examine the genetic consequences of how glacial‐associated sea level change interacted with variable nearshore topography since the last glaciation. We reconstructed the size and distribution of areas suitable for tidal estuary formation from the last glacial maximum, ~20 thousand years ago, to present from San Francisco, California,USA(~38°N) to Reforma, Sinaloa, Mexico (~25°N). We assessed range‐wide genetic structure and diversity of three codistributed tidal estuarine fishes (California Killifish, Shadow Goby, Longjaw Mudsucker) along ~4,600 km using mitochondrial control region andcytB sequence, and 16–20 microsatellite loci from a total of 524 individuals. Results show that glacial‐associated sea level change limited estuarine habitat to few, widely separated refugia at glacial lowstand, and present‐day genetic clades were sourced from specific refugia. Habitat increased during postglacial sea level rise and refugial populations admixed in newly formed habitats. Continental shelves with active tectonics and/or low sediment supply were steep and hosted fewer, smaller refugia with more genetically differentiated populations than on broader shelves. Approximate Bayesian computation favoured the refuge–recolonization scenarios from habitat models over isolation by distance and seaway alternatives, indicating isolation at lowstand is a major diversification mechanism among these estuarine (and perhaps other) coastal species. Because sea level change is a global phenomenon, we suggest this top‐down physical control of extirpation–isolation–recolonization may be an important driver of genetic diversification in coastal taxa inhabiting other topographically complex coasts globally during the Mid‐ to Late Pleistocene and deeper timescales.
Centrality of spirituality/religion in the culture of palliative care service in Indonesia: An ethnographic study

Published: January 2018

AbstractExperiencing life‐threatening illness could impact on an individual’s spirituality or religious beliefs. In this paper, we report on a study which explored cultural elements that influence the provision of palliative care for people with cancer. A contemporary ethnographic approach was adopted. Observations and interviews were undertaken over 3 months with 48 participants, including palliative care staff, patients, and their families. An ethnographic data analysis framework was adopted to assist in the analysis of data at item, pattern, and structural levels. Religion was identified as central to everyday life, with all participants reporting being affiliated to particular religions and performing their religious practices in their daily lives. Patients’ relatives acknowledged and addressed patients’ needs for these practices. Staff provided spiritual care for the patients and their relatives in the form of religious discussion and conducting prayers together. An understanding that religious and spiritual practices are integral cultural elements and of fundamental importance to the holistic health of their patients is necessary if health‐care professionals are to support patients and their families in end‐of‐life care.

Carolibrandtia nom. nov. as a replacement name for Brandtia Hoshina (Chlorellaceae, Trebouxiophyceae)
Authors: Hoshina Ryo , Nakada Takashi 
Published: January 2018

SUMMARYRecently, the genus name Brandtia Hoshina was given for a chlorellacean symbiotic alga residing in some ciliate species. However, it was found that Brandtia Hoshina 2017 is an illegitimate later homonym of Brandtia Kunth 1831. Therefore, a replacement name, Carolibrandtia nom. nov., for Brandtia Hoshina is here proposed.
Human Agency in Disaster Planning: A Systems Approach

Published: January 2018

AbstractCurrent approaches to risk management place insufficient emphasis on the system knowledge available to the assessor, particularly in respect of the dynamic behavior of the system under threat, the role of human agents (HAs), and the knowledge available to those agents. In this article, we address the second of these issues. We are concerned with a class of systems containing HAs playing a variety of roles as significant system elements—as decisionmakers, cognitive agents, or implementers—that is, human activity systems. Within this family of HAS, we focus on safety and mission‐critical systems, referring to this subclass as critical human activity systems (CHASs). Identification of the role and contribution of these human elements to a system is a nontrivial problem whether in an engineering context, or, as is the case here, in a wider social and public context. Frequently, they are treated as standing apart from the system in design or policy terms. Regardless of the process of policy definition followed, analysis of the risk and threats to such a CHAS requires a holistic approach, since the effect of undesirable, uninformed, or erroneous actions on the part of the human elements is both potentially significant to the system output and inextricably bound together with the nonhuman elements of the system. We present a procedure for identifying the potential threats and risks emerging from the roles and activity of those HAs, using the 2014 flooding in southwestern England and the Thames Valley as a contemporary example.

AbstractWe developed a risk assessment of human salmonellosis associated with consumption of alfalfa sprouts in the United States to evaluate the public health impact of applying treatments to seeds (0–5‐log10 reduction in Salmonella) and testing spent irrigation water (SIW) during production. The risk model considered variability and uncertainty in Salmonella contamination in seeds, Salmonella growth and spread during sprout production, sprout consumption, and Salmonella dose response. Based on an estimated prevalence of 2.35% for 6.8 kg seed batches and without interventions, the model predicted 76,600 (95% confidence interval (CI) 15,400–248,000) cases/year. Risk reduction (by 5‐ to 7‐fold) predicted from a 1‐log10 seed treatment alone was comparable to SIW testing alone, and each additional 1‐log10 seed treatment was predicted to provide a greater risk reduction than SIW testing. A 3‐log10 or a 5‐log10 seed treatment reduced the predicted cases/year to 139 (95% CI 33–448) or 1.4 (95% CI <1–4.5), respectively. Combined with SIW testing, a 3‐log10 or 5‐log10 seed treatment reduced the cases/year to 45 (95% CI 10–146) or <1 (95% CI <1–1.5), respectively. If the SIW coverage was less complete (i.e., less representative), a smaller risk reduction was predicted, e.g., a combined 3‐log10 seed treatment and SIW testing with 20% coverage resulted in an estimated 92 (95% CI 22–298) cases/year. Analysis of alternative scenarios using different assumptions for key model inputs showed that the predicted relative risk reductions are robust. This risk assessment provides a comprehensive approach for evaluating the public health impact of various interventions in a sprout production system.
Random Networks, Graphical Models and Exchangeability
Authors: Lauritzen Steffen , Rinaldo Alessandro , Sadeghi Kayvan 
Published: January 2018

SummaryWe study conditional independence relationships for random networks and their interplay with exchangeability. We show that, for finitely exchangeable network models, the empirical subgraph densities are maximum likelihood estimates of their theoretical counterparts. We then characterize all possible Markov structures for finitely exchangeable random graphs, thereby identifying a new class of Markov network models corresponding to bidirected Kneser graphs. In particular, we demonstrate that the fundamental property of dissociatedness corresponds to a Markov property for exchangeable networks described by bidirected line graphs. Finally we study those exchangeable models that are also summarized in the sense that the probability of a network depends only on the degree distribution, and we identify a class of models that is dual to the Markov graphs of Frank and Strauss. Particular emphasis is placed on studying consistency properties of network models under the process of forming subnetworks and we show that the only consistent systems of Markov properties correspond to the empty graph, the bidirected line graph of the complete graph and the complete graph.
CMV Biorthogonal Laurent Polynomials: Perturbations and Christoffel Formulas
Authors: Ariznabarreta Gerardo , Mañas Manuel , Toledano Alfredo 
Published: January 2018

AbstractQuasidefinite sesquilinear forms for Laurent polynomials in the complex plane and corresponding CMV biorthogonal Laurent polynomial families are studied. Bivariate linear functionals encompass large families of orthogonalities such as Sobolev and discrete Sobolev types. Two possible Christoffel transformations of these linear functionals are discussed. Either the linear functionals are multiplied by a Laurent polynomial, or are multiplied by the complex conjugate of a Laurent polynomial. For the Geronimus transformation, the linear functional is perturbed in two possible manners as well, by a division by a Laurent polynomial or by a complex conjugate of a Laurent polynomial, in both cases the addition of appropriate masses (linear functionals supported on the zeros of the perturbing Laurent polynomial) is considered. The connection formulas for the CMV biorthogonal Laurent polynomials, its norms, and Christoffel–Darboux kernels, in all the four cases, are given. For the Geronimus transformation, the connection formulas for the second kind functions and mixed Christoffel–Darboux kernels are also given in the two possible cases. For prepared Laurent polynomials, i.e., of the form , , these connection formulas lead to quasideterminantal (quotient of determinants) Christoffel formulas for all the four transformations, expressing an arbitrary degree perturbed biorthogonal Laurent polynomial in terms of 2n unperturbed biorthogonal Laurent polynomials, their second kind functions or Christoffel–Darboux kernels and its mixed versions. Different curves are presented as examples, such as the real line, the circle, the Cassini oval, and the cardioid. The unit circle case, given its exceptional properties, is discussed in more detail. In this case, a particularly relevant role is played by the reciprocal polynomial, and the Christoffel formulas provide now with two possible ways of expressing the same perturbed quantities in terms of the original ones, one using only the nonperturbed biorthogonal family of Laurent polynomials, and the other using the Christoffel–Darboux kernels and its mixed versions, as well. Two examples are discussed in detail.
Effect of length of dental resident clinical rotations on patient behavior
Authors: Lau Agnes 
Published: January 2018

ABSTRACTAimThe purpose of this retrospective chart review study was to determine if the length of residents’ comprehensive dental care rotations in a general practice residency affected late cancellations, broken appointments, completion of treatment, timeliness of recall visits, emergency visits, and the need for redo of restorations and prostheses.MethodsPatients who presented for comprehensive care from 2010 to 2013, during which residents had 3‐ to 4‐month dental clinic rotations, comprised Group 1, and patients who presented for comprehensive care from 2013 to 2016, during which residents had 11‐month dental clinic rotations, comprised Group 2. Subjects were excluded if they only presented for emergency care, they had only one visit, or their care was delivered in both time periods. There were 105 patients in Group 1 and 55 patients in Group 2.ResultsThe statistically significant results were that Group 1 patients had more late cancellations and broken appointments and failed to reach recall status more often than Group 2 patients, and that Group 1 patients had fewer emergency visits.ConclusionWithin the limitations of this retrospective study, the results suggest that short block rotations have an adverse effect on resident experience and outcomes of patient care in a hospital outpatient setting.
Home hemodialysis education during postdoctoral training: Challenges and innovations
Authors: Glickman Joel D. , Seshasai Rebecca Kurnik 
Published: January 2018

AbstractInadequate education in home hemodialysis (HHD) fellowship training might contribute to underutilization of this modality in the United States. Most graduates of nephrology fellowships do not grade themselves as competent in HHD suggesting that fellowship training in HHD is inadequate. An essential component for fellow education is at least one faculty member with expertise in HHD who is passionate about promoting the use of this modality. At a minimum, fellow training should utilize a curriculum that includes both lectures about HHD and outpatient clinical exposure to this modality over a period of at least 6‐12 months. Fellows benefit from the opportunity to transition at least three patients to a home modality to gain experience with modality education, access placement, initial prescriptions, and home dialysis training. They should spend time with HHD training nurses to learn more about modality education, observe nurse intake interviews with patients in order to learn the criteria for entrance into the home dialysis program as well as recognize how to identify potential barriers to successful home dialysis therapy. To expose fellows to problems that do not occur during clinic visits fellows are encouraged to take first call during the day for HHD patients. There are many opportunities to do research and quality improvement projects which might also propel some fellows into an academic career as a home dialysis nephrologist.
Down‐slope facies variability within deep‐water channel systems: Insights from the Upper Cretaceous Cerro Toro Formation, southern Patagonia

Published: January 2018

AbstractIn southern Patagonia, outcrops of the Upper Cretaceous Cerro Toro Formation preserve a >150 km long deep‐water axial channel belt in the Magallanes–Austral Basin, providing a unique opportunity to investigate longitudinal variations in the depositional characteristics of a deep‐water channel system. This study documents sedimentological, stratigraphical and geochronological data from the Cerro Toro Formation in the Argentine sector of the basin. New results are integrated with previous work from the Chilean basin sector to conduct a basin‐scale comparison of the timing of deposition, provenance and lithofacies proportions. The Cerro Toro channel belt includes a nearly 1000 m thick section characterized by high‐density turbidites and mass‐wasting deposits. Two ash beds from the base of the section yield U–Pb zircon ages of 90·4 ± 2 Ma and 88·0 ± 3 Ma, indicating similar initiation ages as documented in the Chilean sector. The U–Pb detrital zircon age spectra from samples in the study area reveal similar provenance trends to samples from the Chilean basin sector, with peak age populations at 310 to 260 Ma, 160 to 135 Ma and 110 to 82 Ma. The maximum depositional age of the channel belt in the Argentine sector is 87·8 ± 1·5 Ma and all new geochronology data corroborate an 86 to 80 Ma depositional age for the main Cerro Toro channel belt. Statistical analyses of 7370 beds from nearly 8000 m of new and previously published stratigraphic sections along the entire outcrop belt suggest progressive variations in the down‐system proportion of lithofacies. In the up‐slope region, lithofacies representing mass wasting processes (for example, debris‐flow and mass‐transport deposits) account for ca 29% of the stratigraphic thickness, as opposed to 5% in the down‐slope region of the channel belt, where turbidity current deposits are more prevalent. The proportion of beds >1 m thick also decreases systematically down slope, particularly for conglomeratic turbidite deposits. This work highlights that: (i) the proportion of thick beds and distribution of lithofacies are key down‐system changes in the stratigraphic fill of this deep‐water channel belt; (ii) detrital zircon trends suggest a relatively well‐mixed longitudinal depositional system; and (iii) geochronology of the main Cerro Toro outcrop belt supports but does not necessitate the model of a single, roughly age‐equivalent, channel system. This study has implications for understanding the downslope variability in depositional processes, stratigraphic architecture and reservoir quality of submarine channel systems.
Assessment of fog collection as a sustainable water resource in the southwest of the Kingdom of Saudi Arabia
Authors: Algarni Salem 
Published: January 2018

AbstractThe Kingdom of Saudi Arabia (KSA) is an arid dessert with less than 100 mm yearly rainfall in addition to a high‐water consumption per capita. The collection of fog water is a simple and sustainable technology and may offer a supplementary water supply. Data were collected for a whole year from the Rayda reserve weather station, and two standard fog collectors (SFCs) were installed near the weather station. The results indicated that the average water collected by the local mesh was 6.7 L/m2/day, compared with 5.5 L/m2/day collected by the imported mesh. The highest quantity of water was collected in March by the local mesh, at 22 L/m2/day. The effectiveness of the fog collection was calculated and compared with the international standards. The obtained results indicate that fog can be utilized as a supplementary water source for the agriculture sector in the southwest KSA.
