Published: April 2017

BackgroundObservations in psychiatric in-patient settings are used to reduce suicide, self-harm, violence and absconding risk. The study aims were to describe the characteristics of in-patients who died by suicide under observation and examine their service-related antecedents.MethodA national consecutive case series in England and Wales (2006–2012) was examined.ResultsThere were 113 suicides by in-patients under observation, an average of 16 per year. Most were under intermittent observation. Five deaths occurred while patients were under constant observation. Patient deaths were linked with the use of less experienced staff or staff unfamiliar with the patient, deviation from procedures and absconding.ConclusionsWe identified key elements of observation that could improve safety, including only using experienced and skilled staff for the intervention and using observation levels determined by clinical need not resources.
Relocating Pastorian Medicine: Accommodation and Acclimatization of Pastorian Practices against Smallpox at the Pasteur Institute of Chengdu, China, 1908–1927
Authors: Liu Chien-Ling 
Published: April 2017

ArgumentRevising the diffusionist view of current scholarship on the Pasteur Institutes in China, this paper demonstrates the ways in which local networks and circumstances informed the circulation and construction of knowledge and practices relating to smallpox prophylaxis in the Southwest of China during the early twentieth century. I argue that the Pasteur Institute of Chengdu did not operate in a natural continuity with the preceding local French medical institutions, but rather presented an intentional break from them. This Institute, as the first established by the French in China, strove for political and administrative independence both from the Chinese authority and from the Catholic Church. Yet, its operation realized political independence only partially. The founding of this Institute was also an attempt to satisfy the medical demand for local vaccine production. However, even though the Institute succeeded at producing the Jennerian vaccine locally, its production needed to accommodate local conditions pertaining to the climate, vaccine strains, and animals. Furthermore, vaccination had to conform to Chinese variolation, including its social and medical practices, in order to achieve the collaboration of local Chinese traditional practitioners with French colonial physicians, who were Pastorian-trained and worked at the Pasteur Institute of Chengdu. Thus the nature of the Pastorian work in Chengdu was not an imposition of foreign standards and practices, but rather a mutual compromise and collaboration between the French and the Chinese.
Flattening and Unpacking Human Genetic Variation in Mexico, Postwar to Present

Published: April 2017

ArgumentThis paper analyzes the research strategies of three different cases in the study of human genetics in Mexico – the work of Rubén Lisker in the 1960s, INMEGEN's mapping of Mexican genomic diversity between 2004 and 2009, and the analysis of Native American variation by Andrés Moreno and his colleagues in contemporary research. We make a distinction between an approach that incorporates multiple disciplinary resources into sampling design and interpretation (unpacking), from one that privileges pragmatic considerations over more robust multidisciplinary analysis (flattening). These choices have consequences for social, demographic, and biomedical practices, and also for accounts of genetic variation in human populations. While the former strategyunpacksfine-grained genetic variation – favoring precision and realism, the latter tends toflattenindividual differences and historical depth in lieu of generalization.
The mediating roles of cortisol reactivity and executive functioning difficulties in the pathways between childhood histories of emotional insecurity and adolescent school problems

Published: April 2017

AbstractThis study tested a hypothesized cascade in which children's insecure representations of the interparental relationship increase their school problems by altering children's cortisol reactivity to stress and their executive functioning. Participants included 235 families. The first of five measurement occasions occurred when the children were in kindergarten (M age = 6 years), and they were followed through the transition to high school. The results indicated that children's histories of insecure representations of the interparental relationship during the early school years were associated with executive functioning difficulties in adolescence (M age = 14 years). This in turn predicted subsequent increases in school adjustment difficulties 1 year later. In addition, elevated cortisol reactivity to interadult conflict mediated the association between early histories of insecurity and subsequent executive function problems in adolescence.

Published: April 2017

AbstractIntroductionDisasters will continue to occur throughout the world and it is the responsibility of the government, health care systems, and communities to adequately prepare for potential catastrophic scenarios. Unfortunately, low-and-middle-income countries (LMICs) are especially vulnerable following a disaster. By understanding disaster preparedness and risk perception, interventions can be developed to improve community preparedness and avoid unnecessary mortality and morbidity following a natural disaster.ProblemThe purpose of this study was to assess disaster preparedness and risk perception in communities surrounding Trujillo, Peru.MethodsAfter designing a novel disaster preparedness and risk perception survey based on guidelines from the International Federation of Red Cross and Red Crescent Societies (IFRC; Geneva, Switzerland), investigators performed a cross-sectional survey of potentially vulnerable communities surrounding Trujillo, Peru. Data were entered and analyzed utilizing the Research Electronic Data Capture (REDCap; Harvard Catalyst; Boston, Massachusetts USA) database.ResultsA total of 230 study participants were surveyed, composed of 37% males, 63% females, with ages ranging from 18-85 years old. Those surveyed who had previously experienced a disaster (41%) had a higher perception of future disaster occurrence and potential disaster impact on their community. Overall, the study participants consistently perceived that earthquakes and infection had the highest potential impact of all disasters. Twenty-six percent of participants had an emergency supply of food, 24% had an emergency water plan, 24% had a first aid kit at home, and only 20% of the study participants had an established family evacuation plan.ConclusionNatural and man-made disasters will remain a threat to the safety and health of communities in all parts of the world, especially within vulnerable communities in LMICs; however, little research has been done to identify disaster perception, vulnerability, and preparedness in LMIC communities. The current study established that selected communities near Trujillo, Peru recognize a high disaster impact from earthquakes and infection, but are not adequately prepared for potential future disasters. By identifying high-risk demographics, targeted public health interventions are needed to prepare vulnerable communities in the following areas: emergency food supplies, emergency water plan, medical supplies at home, and establishing evacuation plans.StewartM,GrahmannB,FillmoreA,BensonLS.Rural community disaster preparedness and risk perception in Trujillo, Peru.Prehosp Disaster Med.2017;32(4):387–392.
TWO TYPES OF LEGAL WRONGDOING
Authors: Newhouse M.E. 
Published: April 2017

ABSTRACTThere are two distinct types of legal wrongdoing: civil and criminal. This article demonstrates in three ways that Immanuel Kant's Universal Principle of Right, properly interpreted, offers a plausible and resilient account of this important distinction. First, Kant's principle correctly identifies attempted crimes as crimes themselves even when they do not violate the rights of any individual. Second, it justifies our treatment of reckless endangerment as a crime by distinguishing it from ordinary negligence, traditionally thought to be only civilly wrong. Third, it explains and justifies differences between the features of traditional criminal punishments and the features of civil remedies. Moreover, the Universal Principle of Right yields a Kantian standard for criminal wrongdoing that is compelling enough to inform future philosophical inquiries into the nature and limits of the state's criminal lawmaking authority.
Atypical Local Interference Affects Global Processing in Children with Neurofibromatosis Type 1

Published: April 2017

AbstractObjectives: To examine hierarchical visuospatial processing in children with neurofibromatosis type 1 (NF1), a single gene disorder associated with visuospatial impairments, attention deficits, and executive dysfunction. Methods: We used a modified Navon paradigm consisting of a large “global” shape composed of smaller “local” shapes that were either congruent (same) or incongruent (different) to the global shape. Participants were instructed to name either the global or local shape within a block. Reaction times, interference ratios, and error rates of children with NF1 (n=30) and typically developing controls (n=24) were compared. Results: Typically developing participants demonstrated the expected global processing bias evidenced by a vulnerability to global interference when naming local stimuli without a cost of congruence when naming global stimuli. NF1 participants, however, experienced significant interference from the unattended level when naming both local and global levels of the stimuli. Conclusions: Findings suggest that children with NF1 do not demonstrate the typical human bias of processing visual information from a global perspective. (JINS, 2017, 23, 446–450)

Published: April 2017

AbstractBackgroundThe aim of this study was to compare the dosimetric parameters and effects of simultaneous integrated boost (SIB) and traditional sequential electron boost, after helical tomotherapy, because of the lack of studies in this field in the current literature.MethodsComputed tomographic data of 14 patients who received SIB in 2012–2015 were collected from Hong Kong Sanatorium & Hospital. New tomotherapy with SIB plans and tomotherapy with sequential boost plans were generated for each patient, and results were compared.ResultsConformation number, mean dose, dose received by 95% volume (both sides), ipsilateral lung volume receiving 20 Gy (V20) and skin dose (right side) were found to be significantly better for SIB (p<0·05), however coverage index and gross target volume dose showed no significant difference, and heart dose was significantly higher for SIB on the right side.ConclusionTomotherapy with SIB may be able to offer less organ at risk dose (except for the heart), while maintaining the ability to deliver adequate dose coverage.

AbstractBackground and purposeTo determine which concomitant boost technique is dosimetrically superior in the treatment of breast cancer; volumetric-modulated arc therapy (VMAT) or fixed field intensity-modulated radiotherapy (ff-IMRT).Materials and methodsIn total, 30 breast patients were re-planned with both VMAT and fixed field concomitant boost intensity-modulated radiotherapy techniques. A hybrid technique was used delivering 80% of the dose through tangential beams and 20% through an integrated boost. A two-tailed t-test sample for means was used to compare the dosimetric differences between the techniques.ResultsMaximum dose was statistically lower for VMAT; 103·2 versus 103·7% for ff-IMRT along with statistically lower V2 Gy doses to the contralateral lung (0·7 versus 1·6%) and heart for both left- (19·0%/22·6%), and right- (5·5%/8·8%) sided patients, respectively. ff-IMRT boasted significantly lower ipsilateral lung V20, V18 and V10 Gy (7·9/8·6/13·1 versus 8·1/8·8/13·4%) than VMAT, respectively. No differences were found with minimum coverage, mean dose and V5 Gy to all organs at risk (OARs).ConclusionVMAT and ff-IMRT techniques demonstrate excellent target coverage and OAR sparing facilitated by the hybrid planning technique and deep inspiration breath hold. There is no obvious dosimetrically superior option between the two techniques. Reduced treatment times with VMAT make it more desirable to implement clinically.
Can reducing tillage and increasing crop diversity benefit grain and forage production?

Published: April 2017

AbstractBenefits of reduced tillage and diverse crop rotations include reversing soil C loss, and improving soil quality and function. However, adoption of these strategies is lagging, particularly in the Upper Midwest, due to a perception that reduced tillage lowers crop yields. Therefore, an 8-year comparison of these conservation systems with a conventional, tilled, 2-year rotation system was conducted to evaluate effects on yields, system productivity (measured with potential gross returns) and weed seed densities. This study compared conventional moldboard plow + chisel till (CT) to reduced strip-tillage + no-tillage (ST), each with a 2-year (2y) or 4-year (4y) crop rotation, abbreviated as CT-2y, CT-4y, ST-2y and ST-4y. The 2y rotation was corn (Zea maysL.) and soybean (Glycine max[L.] Merr.); the 4y rotation was corn, soybean, spring wheat (Triticum aestivumL.) underseeded with alfalfa (Medicago sativaL.) and alfalfa. Only corn grain was significantly influenced by tillage strategy; CT systems yielded more than ST systems, regardless of rotation. Soybean grain yields were similar among CT-2y, CT-4y, ST-4y and lowest in the ST-2y. Yields of wheat and alfalfa were the same under both tillage strategies. Weed seed densities were higher in wheat and alfalfa, followed by corn then soybean, but were not influenced by tillage or rotation, nor universally negatively correlated to yield. Due to greater corn yields, overall system productivity was highest in CT-2y, the same between CT-4y and ST-2y, and lowest in ST-4y. Within years, productivity of CT-2y was different from only one other system at a time in 3 of 8 years and had the same productivity as all systems in another 3 of 8 years. Additionally, the similarity of productivity among three of four systems in 6 of 8 years indicated reduced tillage and diverse rotations have potential for adoption. Results support the need for research on a rotational tillage strategy, i.e., moldboard plowing before corn, to improve overall productivity if using ST before soybean, wheat and alfalfa.
Property as complex interaction
Authors: SMITH HENRY E. 
Published: April 2017

AbstractIn his important article, Benito Arruñada draws out the significance of sequential exchange for property rights and traces inadequacies in the economics of property rights to its overly contractual focus, to the exclusion of multiple transactions on the same asset. In this comment, I argue that although Arruñada's problem is a genuine one, it is part of a larger inadequacy in the economic analysis of property rights: property institutions have to manage complexity stemming from many kinds of interactions, making it problematic to focus solely on local interactions. Modular structures in property, including legal ‘things’ themselves, serve to manage this complexity. The larger problem of complexity allows us to set sequential exchange in its proper context.

Abstract
Gradients of oxygen (O2) and pH, as well as small-scale fluxes of carbon (C), nitrogen (N) and O2 were investigated under different partial pressures of carbon dioxide (pCO2) in field-collected colonies of the marine dinitrogen (N2)-fixing cyanobacterium Trichodesmium. Microsensor measurements indicated that cells within colonies experienced large fluctuations in O2, pH and CO2 concentrations over a day–night cycle. O2 concentrations varied with light intensity and time of day, yet colonies exposed to light were supersaturated with O2 (up to ~200%) throughout the light period and anoxia was not detected. Alternating between light and dark conditions caused a variation in pH levels by on average 0.5 units (equivalent to 15 nmol l−1 proton concentration). Single-cell analyses of C and N assimilation using secondary ion mass spectrometry (SIMS; large geometry SIMS and nanoscale SIMS) revealed high variability in metabolic activity of single cells and trichomes of Trichodesmium, and indicated transfer of C and N to colony-associated non-photosynthetic bacteria. Neither O2 fluxes nor C fixation by Trichodesmium were significantly influenced by short-term incubations under different pCO2 levels, whereas N2 fixation increased with increasing pCO2. The large range of metabolic rates observed at the single-cell level may reflect a response by colony-forming microbial populations to highly variable microenvironments.
Ecological dynamics and co-occurrence among marine phytoplankton, bacteria and myoviruses shows microdiversity matters
Authors: Needham David M , Sachdeva Rohan , Fuhrman Jed A 
Published: April 2017

Abstract
Numerous ecological processes, such as bacteriophage infection and phytoplankton–bacterial interactions, often occur via strain-specific mechanisms. Therefore, studying the causes of microbial dynamics should benefit from highly resolving taxonomic characterizations. We sampled daily to weekly over 5 months following a phytoplankton bloom off Southern California and examined the extent of microdiversity, that is, significant variation within 99% sequence similarity clusters, operational taxonomic units (OTUs), of bacteria, archaea, phytoplankton chloroplasts (all via 16S or intergenic spacer (ITS) sequences) and T4-like-myoviruses (via g23 major capsid protein gene sequence). The extent of microdiversity varied between genes (ITS most, g23 least) and only temporally common taxa were highly microdiverse. Overall, 60% of taxa exhibited microdiversity; 59% of these had subtypes that changed significantly as a proportion of the parent taxon, indicating ecologically distinct taxa. Pairwise correlations between prokaryotes and myoviruses or phytoplankton (for example, highly microdiverse Chrysochromulina sp.) improved when using single-base variants. Correlations between myoviruses and SAR11 increased in number (172 vs 9, Spearman&gt;0.65) and became stronger (0.61 vs 0.58, t-test: P&lt;0.001) when using SAR11 ITS single-base variants vs OTUs. Whole-community correlation between SAR11 and myoviruses was much improved when using ITS single-base variants vs OTUs, with Mantel rho=0.49 vs 0.27; these results are consistent with strain-specific interactions. Mantel correlations suggested &gt;1 μm (attached/large) prokaryotes are a major myovirus source. Consideration of microdiversity improved observation of apparent host and virus networks, and provided insights into the ecological and evolutionary factors influencing the success of lineages, with important implications to ecosystem resilience and microbial function.

AbstractChanges in penguin populations on the Antarctic Peninsula have been linked to several environmental factors, but the potentially devastating impact of volcanic activity has not been considered. Here we use detailed biogeochemical analyses to track past penguin colony change over the last 8,500 years on Ardley Island, home to one of the Antarctic Peninsula’s largest breeding populations of gentoo penguins. The first sustained penguin colony was established on Ardley Island c. 6,700 years ago, pre-dating sub-fossil evidence of Peninsula-wide occupation by c. 1,000 years. The colony experienced five population maxima during the Holocene. Overall, we find no consistent relationships with local-regional atmospheric and ocean temperatures or sea-ice conditions, although the colony population maximum, c. 4,000–3,000 years ago, corresponds with regionally elevated temperatures. Instead, at least three of the five phases of penguin colony expansion were abruptly ended by large eruptions from the Deception Island volcano, resulting in near-complete local extinction of the colony, with, on average, 400–800 years required for sustainable recovery.
Topological superconductivity in monolayer transition metal dichalcogenides

Published: April 2017

AbstractTheoretically, it has been known that breaking spin degeneracy and effectively realizing spinless fermions is a promising path to topological superconductors. Yet, topological superconductors are rare to date. Here we propose to realize spinless fermions by splitting the spin degeneracy in momentum space. Specifically, we identify monolayer hole-doped transition metal dichalcogenide (TMD)s as candidates for topological superconductors out of such momentum-space-split spinless fermions. Although electron-doped TMDs have recently been found superconducting, the observed superconductivity is unlikely topological because of the near spin degeneracy. Meanwhile, hole-doped TMDs with momentum-space-split spinless fermions remain unexplored. Employing a renormalization group analysis, we propose that the unusual spin-valley locking in hole-doped TMDs together with repulsive interactions selectively favours two topological superconducting states: interpocket paired state with Chern number 2 and intrapocket paired state with finite pair momentum. A confirmation of our predictions will open up possibilities for manipulating topological superconductors on the device-friendly platform of monolayer TMDs.
