Marine cultural heritage: frontier or centre?
Authors: Lehman Jessica 
Published: September 2018

AbstractMarine cultural heritage is an area of emerging international interest among different sectors of society. Drawing together a diverse set of literatures on marine cultural heritage, maritime archaeology, the development of the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage, and ocean politics more broadly, this paper examines the ways in which marine cultural heritage might be understood as a frontier in terms not only of spatial territory, but also for knowledge, governance, and politics. As such, marine cultural heritage may bring the disciplinary practices of maritime archaeology into contact with more radical marine politics of postcolonial, subaltern, and Black scholarship. This analysis thus suggests stakes of marine cultural heritage for different communities, reaching far beyond the sites and objects themselves, and shows why marine cultural heritage is emerging as an urgent and dynamic concern at the present moment. Yet ultimately, whether or not marine cultural heritage is truly a frontier is a question that has different meanings depending on the perspective from which it is asked. These differing perspectives illuminate the changing meaning of ocean space as well as struggles over material and immaterial marine resources, and suggest that the frontier is itself a contested concept.

AbstractBackgroundProper feeding practices in early life can enhance the full human potential development of children. We aimed to evaluate the impact of a primary health care intervention on infant feeding practices among children from low‐income families.MethodsA cluster randomised controlled trial was conducted in Porto Alegre, Brazil. Healthcare centres were randomised into intervention (n = 9) and control (n = 11) groups. In intervention sites, health workers were trained in accordance with the national guidelines. Infant feeding practices were assessed in children at 6 months (n = 617) and 12 months (n = 516) of age. Feeding practice quality was assessed using the Infant and Child Feeding Index (ICFI). Additionally, we evaluated the introduction of nonrecommended foods.ResultsAt 6 months, the mean ICFI score was higher in the intervention group [MD = 0.22; 95% confidence interval (CI) = 0.24–1.11]. The prevalence of infants who met the recommendation for meat into the food‐frequency score was higher in the intervention than the control group [relative risk (RR) = 1.63; 95% CI = 1.26–2.11]. At 12 months of age, the ICFI mean (MD = 0.23; 95% CI = 0.35–0.56) and the prevalence of children who met the recommendation for dietary diversity (RR = 1.11; 95% CI = 1.01–1.22) and meal frequency (RR = 4.68; 95% CI = 1.34–16.36) were higher in the intervention group, although only among children who had more than seven follow‐up appointments during the first year of life. The children from intervention group had a significant delay for added sugar (MD = 0.51; 95% CI = 0.13–0.89), tea (mean = 0.47; 95% CI = 0.13–0.82), jelly (MD = 0.35; 95% CI = 0.11–0.58) and filled cookies (MD = 0.29; 95% CI = 0.06–0.52) compared to the control group.ConclusionsThe health workers’ training was effective with respect to improving infant feeding practices.

ObjectivesTo describe a modified temporary tracheostomy that included placing a Penrose drain sling dorsal to the trachea. To report outcomes and complications in brachycephalic versus non‐brachycephalic breeds.Materials and MethodsRetrospective review of signalment, diagnosis, outcome, complications and management of dogs that underwent modified temporary tracheostomy.ResultsTwenty‐one dogs were included. Tracheostomy tubes were maintained for periods ranging from 1 to 21 days (median 4 days). There were no intraoperative complications or complications related to the placement of the Penrose drain. Postoperative complications occurred in eight dogs, including dislodgement of the tracheostomy tube (n=6), obstruction of the tracheostomy tube (n=1), subcutaneous emphysema and pneumomediastinum (n=1). Twenty dogs survived until discharge; one was euthanised due to persistence of primary disease. The complication rate in brachycephalic breeds and non‐brachycephalic was 37∙5 and 40%, respectively. Tube dwell duration of 4 days or longer was associated with a higher complication rate.Clinical SignificanceThe modified temporary tracheostomy appears to simplify tracheostomy care, improve tracheostomy outcome and reduce tube‐associated mortality compared with standard tracheostomy. In this study, brachycephalic dogs did not have a higher complication rate than non‐brachycephalic dogs.
Assessing the relationship between community dispersion and disturbance in a soft‐sediment ecosystem

AbstractDisturbed ecosystems often exhibit increased community heterogeneity when compared to nondisturbed systems. One way to measure community heterogeneity is statistical dispersion, a measure of how variable individual samples are from the multivariate average of the community condition (species presence/absence and density). In more specific manner, dispersion measures the distance between an individual data point and the centroid, the multivariate average of all data points. Statistical dispersion may be an important parameter to include in environmental assessments, or in studies that attempt to understand the role of disturbances in structuring biological systems. However, disturbances have been observed to increase, decrease, or not impact community dispersion (or community heterogeneity). Therefore, the usefulness of dispersion in studying or identifying disturbances is unclear. We tested if a mechanical disturbance increased community dispersion using the infaunal community of the intertidal mudflats along the north coast of British Columbia, Canada. We observed no statistically significant increase in community dispersion with varying frequency and intensity of a mechanical disturbance. This is likely a result of disturbed and nondisturbed treatments being dominated by the same six taxa, thus minimizing dispersion. Therefore, in ecosystems where differences in community successional stages are subtle (a result of changes in relative abundance rather than species replacement), community dispersion may not be an informative parameter when investigating disturbance. Despite this, we suggest that dispersion can be a useful variable to include in studies attempting to understand or identify disturbances; however, dispersion should only be one parameter amongst many used to understand or identify disturbances.

Published: September 2018

AbstractThe Baby‐friendly Hospital Initiative (BFHI) includes a set of 10 evidenced‐based maternity practices that when used together have been shown to improve breastfeeding outcomes. In 2007, the Centers for Disease Control and Prevention launched the Maternity Practices in Infant Nutrition and Care (mPINC) survey to assess and monitor these and other evidenced‐based maternity practices. The purpose of this study was to explore individual maternity practices measured in the 2013 mPINC survey, along with hospital demographic information, and their relationships with exclusive breastfeeding (EBF) rates, using a sample of United States (U.S.) hospitals. We obtained mPINC survey data from 69 BFHI hospitals and 654 non‐BFHI hospitals in the U.S., and EBF rates from The Joint Commission, a leading hospital accreditation agency. On the basis of linear regression analysis, we found that most maternity practices studied were significantly associated with EBF rates (max adjusted R2 = 14.9%). We found a parsimonious model with an adjusted R2 of 47.3%. This study supports the need for a systematic approach in providing breastfeeding support as no one maternity care practice was able to explain the variability in EBF rates as well as a collection of maternity care practices.

SummaryRice grain filling rate contributes largely to grain productivity and accumulation of nutrients. MicroRNAs (miRNAs) are key regulators of development and physiology in plants and become a novel key target for engineering grain size and crop yield. However, there is little studies, so far, showing the miRNA regulation of grain filling and rice yield, in consequence. Here, we show that suppressed expression of rice miR1432 (STTM1432) significantly improves grain weight by enhancing grain filling rate and leads to an increase in overall grain yield up to 17.14% in a field trial. Molecular analysis identified rice Acyl‐CoA thioesterase (OsACOT), which is conserved with ACOT13 in other species, as a major target of miR1432 by cleavage. Moreover, overexpression of miR1432‐resistant form of OsACOT (OXmACOT) resembled the STTM1432 plants, that is, a large margin of an increase in grain weight up to 46.69% through improving the grain filling rate. Further study indicated that OsACOT was involved in biosynthesis of medium‐chain fatty acids. In addition, RNA‐seq based transcriptomic analyses of transgenic plants with altered expression of miR1432 demonstrated that downstream genes of miR1432‐regulated network are involved in fatty acid metabolism and phytohormones biosynthesis and also overlap with the enrichment analysis of co‐expressed genes of OsACOT, which is consistent with the increased levels of auxin and abscisic acid in STTM1432 and OXmACOT plants. Overall, miR1432‐OsACOT module plays an important role in grain filling in rice, illustrating its capacity for engineering yield improvement in crops.

Published: September 2018

AbstractSocial relationships play a pivotal role in agricultural systems because they influence the economic behavior of stakeholders, but sociological studies aimed at understanding these links have until now not focused much on aquaculture. Here we examine how social capital among communities of the Pampanga River delta in the Philippines plays out in the conduct of aquatic livestock breeding, harvesting, and trading, and how it either facilitates or restrains the transformation of individual livelihoods. Relying on a mixed method of field surveys, participant observation, and questionnaires, we construct an ethnographic portrayal of how the main categories of stakeholder involved in aquaculture (from livestock producers to traders via landless gleaners) elaborate strategies to access or control aquaculture‐related resources. We show that the bonding and bridging efforts to construct social capital are strongly embedded in the cultural matrix, and that they are limited by environmental constraints (ecosystem carrying capacity, exposure to natural hazards) and shaped by historical legacies. The resulting pattern of social interactions is overall successful at buffering the negative impact of external forcing factors such as environmental hazards and global market crashes, but we also show how the different outcomes of social exchange are nonetheless unevenly distributed across the spectrum of stakeholders.

ObjectiveTo determine if adiponectin levels are associated with low grip strength among the elderly independently of insulin resistance and inflammation.Research design and methodsCross-sectional associations were analyzed by logistic regression between low grip strength and body composition, elevated serum adiponectin (≥20 mg/L), and biomarkers of nutritious stasis, insulin resistance and inflammation in 179 community-living Japanese women. Sarcopenia was evaluated using the Asian criteria.ResultsNo women had sarcopenia. In bivariate analyses, low grip strength (n=68) was positively associated with age, log tumor necrosis factor-α (TNF-α) and hyperadiponectinemia (n=37) and inversely with body weight, height, skeletal muscle mass, serum albumin, transthyretin (TTR), fat mass, serum zinc and hemoglobin (all p<0.01). In a fully adjusted model, TTR (0.90: 0.83–0.98, p=0.01) in addition to age (p=0.007), height (p=0.004) and skeletal muscle mass (p=0.008) emerged as independent determinants of low grip strength. When TTR was removed from the full model, TNF-α was associated with low grip strength (7.7; 1.3–45.8, p=0.02). Mean waist circumference and high-density lipoprotein cholesterol did not differ between women with and without low grip strength and were within the respective normal range. Women with hyperadiponectinemia had higher percentage of women with low grip strength and lower grip strength (both p<0.01).ConclusionsHyperadiponectinemia and elevated TNF-α in addition to decreased TTR, a biomarker of age-related catabolic states, were found in community-living Japanese elderly women with low grip strength and preserved muscle mass and insulin sensitivity.

ObjectiveTo investigate the relation of Hashimoto’s thyroiditis (HT) to cholelithiasis and cholecystectomy in a retrospective population-based study.SettingCohort study.ParticipantsWe identified 1268 patients aged ≥20 years with HT between 2000 and 2010 as the study cohort.Primary and secondary outcome measuresPatients without HT were randomly selected from a database and propensity-matched with the study cohort at a 1:4 ratio according to age, sex, comorbidities and year of the index date to measure the incidence of cholelithiasis and cholecystectomy.ResultsThe cumulative incidence of cholelithiasis was higher in the HT cohort than that in the non-HT cohort (log-rank test, p<0.001), with a 1.91-fold higher risk of choleithiasis (95% CI 1.58 to 2.33) after adjustment for comorbidities. The age-specific relative risk of cholelithiasis in the HT cohort was higher than that in the non-HT cohort for patients aged ≥50 years (adjusted HR (aHR)=2.59, 95% CI 1.33 to 5.03). The sex-specific relative risk of cholelithiasis in the HT cohort was higher than that in the non-HT cohort for women (aHR=1.99, 95% CI 1.63 to 2.44). Compared with those in the non-HT cohort, patients with HT without (aHR=1.95, 95% CI 1.53 to 2.49) and with (aHR=1.94, 95% CI 1.51 to 2.49) thyroxine treatment were associated with a higher risk of cholelithiasis. Compared with those in the non-HT cohort, patients with HT had a higher risk of cholecystectomy (aHR=1.28, 95% CI 1.02 to 1.61).ConclusionsInability to obtain information on several potential confounding factors and misclassification of important covariates are the major limitations of the study. Our study indicates HT per se was associated with the development of cholelithiasis, which has been validated by the association between cholecystectomy and HT. Surveys and health education on cholelithiasis in women aged ≥50 years with HT should be considered by clinicians, and further prospective research should be done on this topic.

Published: September 2018

ObjectivesThe aim of this study is to describe the demographics of reported traumatic cardiac arrest (TCA) victims, prehospital resuscitation and survival to hospital rate.SettingHelicopter Emergency Medical Service (HEMS) in south-east England, covering a resident population of 4.5 million and a transient population of up to 8 million people.ParticipantsPatients reported on the initial 999 call to be in suspected traumatic cardiac arrest between 1 July 2016 and 31 December 2016 within the trust’s geographical region were identified. The inclusion criteria were all cases of reported TCA on receipt of the initial emergency call. Patients were subsequently excluded if a medical cause of cardiac arrest was suspected.Outcome measuresPatient records were analysed for actual presence of cardiac arrest, prehospital resuscitation procedures undertaken and for survival to hospital rates.Results112 patients were reported to be in TCA on receipt of the 999/112 call. 51 (46%) were found not to be in TCA on arrival of emergency medical services. Of the ‘not in TCA cohort’, 34 (67%) received at least one advanced prehospital medical intervention (defined as emergency anaesthesia, thoracostomy, blood product transfusion or resuscitative thoracotomy). Of the 61 patients in actual TCA, 10 (16%) achieved return-of-spontaneous circulation. In 45 (88%) patients, the HEMS team escorted the patient to hospital.ConclusionA significant proportion of patients reported to be in TCA on receipt of the emergency call are not in actual cardiac arrest but are critically unwell requiring advanced prehospital medical intervention. Early activation of an enhanced care team to a reported TCA call allows appropriate advanced resuscitation. Further research is warranted to determine which interventions contribute to improved TCA survival.
New Discrete Chaotic Multiplicative Maps Based on the Logistic Map
Authors: Aniszewska Dorota 
Published: September 2018

Chaos is a phenomenon which cannot be predicted if it manifests itself in a nonlinear system. Simple deterministic models, such as the logistic map [Formula: see text], are constructed to capture the essence of processes observed in nature. They are interesting also from a mathematical point of view: nonlinear models can behave in chaotic and complicated ways. The logistic map is the simplest mathematical model exhibiting chaotic behavior. Therefore, its dynamical properties, stable points and stable cycles are well known and widely described. In this paper, the properties of multiplicative calculus were employed to transform the classical logistic map into multiplicative ones. The multiplicative logistic maps were tested for chaotic behavior. The Lyapunov exponents together with the bifurcation diagrams are given.
Superior colliculus signals decisions rather than confidence: analysis of single neurons
Authors: Grimaldi Piercesare , Cho Seong Hah , Lau Hakwan , Basso Michele A. 
Published: September 2018

Recent findings indicate that monkeys can report their confidence in perceptual decisions and that this information is encoded in neurons involved in making decisions, including the lateral intraparietal area (LIP) and the supplementary eye field (SEF). A key issue to consider when studying confidence is that decision accuracy often correlates with confidence reports; when we are performing well, we generally feel more confident. Expanding on work performed in humans, we designed a novel task for monkeys that dissociates perceptual information leading to decisions from perceptual information leading to confidence reports. Using this task, we recently showed that decoded ensemble activity recorded from the superior colliculus (SC) reflected decisions rather than confidence reports. However, our previous population level analysis collapsed over multiple SC neuronal types and therefore left open the possibility that first, individual discharge rates might encode information related to decision confidence, and second, different neuronal cell types within the SC might signal decision confidence independently of decision accuracy. We found that when decision accuracy and decision confidence covaried, modulation occurred primarily in neurons with prelude activity (buildup neurons). However, isolating decision confidence from decision accuracy uncovered that only a few, primarily buildup neurons showed signals correlating uniquely with decision confidence and the effect sizes were very small. Based on this work and our previous work using decoding methods, we conclude that neuronal signals for decision confidence, independent of decision accuracy, are unlikely to exist at the level of single or populations of neurons in the SC. Our results together with other recent work call into question normative models of confidence based on the optimal readout of decision signals. NEW & NOTEWORTHY Models of decision confidence suggest that our sense of confidence is an optimal readout of perceptual decision signals. Here, we report that a subcortical area, the superior colliculus (SC), contains neurons with activity that signal decisions and confidence in a task in which decision accuracy and confidence covary, similar to area lateral intraparietal area in cortex. The signals from SC occur primarily in the neurons with prelude activity (buildup neurons). However, in a task that dissociates decision accuracy from decision confidence, we find that only a few individual neurons express unique signals of confidence. These results call into question normative models of confidence based on optimal readout of perceptual decision signals.
Movement and perception recalibrate differently across multiple days of locomotor learning

Published: September 2018

Learning a new movement through error-based adaptation leads to recalibration of movement and altered perception of that movement. Although presumed to be closely related, the relationship between adaptation-based motor and perceptual changes is not well understood. Here we investigated the changes in motor behavior and leg speed perception over 5 days of split-belt treadmill adaptation. We specifically wanted to know if changes in the perceptual domain would demonstrate savings-like behavior (i.e., less recalibration with more practice) and if these changes would parallel the savings observed in the motor domain. We found that the recalibration of leg speed perception decreased across days of training, indicating savings-like behavior in this domain. However, we observed that the magnitude of savings across days was different between motor and perceptual domains. These findings suggest a degree of independence between the motor and perceptual processes that occur with locomotor adaptation. NEW & NOTEWORTHY Error-based adaptation learning drives changes in movement and perception of movement. Are these changes across domains linked or simply coincidental? Here, we studied changes in movement and perception across 5 days of repeated locomotor adaptation. Savings-like behavior in the motor and perceptual domains developed with different magnitudes and over different timescales, leading us to conclude that motor and perceptual processes operate at least somewhat independently during locomotor adaptation.
