Selectivity matters: Rules of thumb for management of plate‐sized, sex‐changing fish in the live reef food fish trade
Authors: Kindsvater Holly K , Reynolds John D , Sadovy de Mitcheson Yvonne , Mangel Marc 
Published: February 2017

AbstractEffective management of fisheries depends on the selectivity of different fishing methods, control of fishing effort and the life history and mating system of the target species. For sex‐changing species, it is unclear how the truncation of age‐structure or selection of specific size or age classes (by fishing for specific markets) affects population dynamics. We specifically address the consequences of plate‐sized selectivity, whereby submature, “plate‐sized” fish are preferred in the live reef food fish trade. We use an age‐structured model to investigate the decline and recovery of populations fished with three different selectivity scenarios (asymptotic, dome‐shaped and plate‐sized) applied to two sexual systems (female‐first hermaphroditism and gonochorism). We parameterized our model with life‐history data from Brown‐marbled grouper (Epinephelus fuscoguttatus) and Napoleon fish (Cheilinus undulatus). “Plate‐sized” selectivity had the greatest negative effect on population trajectories, assuming accumulated fishing effort across ages was equal, while the relative effect of fishing on biomass was greatest with low natural mortality. Fishing such sex‐changing species before maturation decreased egg production (and the spawning potential ratio) in two ways: average individual size decreased and, assuming plasticity, females became males at a smaller size. Somatic growth rate affected biomass if selectivity was based on size at age because in slow growers, a smaller proportion of total biomass was vulnerable to fishing. We recommend fisheries avoid taking individuals near their maturation age, regardless of mating system, unless catch is tightly controlled. We also discuss the implications of fishing post‐settlement individuals on population dynamics and offer practical management recommendations.
Asymmetric Relationship between Investors' Sentiment and Stock Returns: Evidence from a Quantile Non‐causality Test

Published: February 2017

AbstractThis study investigates the causal relationship between investor sentiment and stock returns in the USA by conducting a quantile Granger non‐causality test. Employing two proxies for investor sentiment – the sentiment index developed by Baker and Wurgler in 2007 and the University of Michigan Consumer Survey, a consumer confidence index – we find that the causal relationship between investor sentiment and stock returns strengthens when a tail quantile interval is considered. This finding implies that the investor sentiment could provide the incremental predictability for the stock returns under the extreme market situation, which cannot be found using a traditional Granger causality test. Interestingly, the findings can be explained by investors' loss aversion and herding behavior.

AbstractAimPleistocene climatic oscillations induced range fluctuations in African rain forest organisms and may have shaped species diversification through allopatric speciation events. We compared the spatial genetic structure of two forest species that live in obligate symbiosis and thus must have experienced the same range fluctuations, as a means to discriminate incipient speciation from transient differentiation simply resulting from past divergence.LocationWestern central Africa.MethodsWe genotyped 765 individuals of the tree Barteria fistulosa and 605 colonies of its symbiotic ant Tetraponera aethiops at 12 and 13 microsatellite loci, respectively. We compared the spatial genetic structure of the two symbionts by using Bayesian clustering algorithms, isolation‐by‐distance analyses and clines of synthetic alleles. We used species niche modelling (climatic and soil variables) to investigate ecological variables associated with genetic discontinuities in tree populations.ResultsThe trees and the ants showed congruent patterns of spatial genetic structure. However, the trees showed a very steep genetic discontinuity between groups north and south of latitude 1° N, which was much weaker in the ants. There was no evidence for effective gene flow between the two tree lineages in contact at the transition zone, despite the presence of a few hybrids. Niche modelling did not predict the occurrence of northern trees south of this genetic transition, and vice versa.Main conclusionsThe genetic discontinuity near latitude 1° N is inferred to be a tension zone resulting from reproductive incompatibilities between previously allopatric tree lineages. This tension zone may have stabilized at a climatic transition (between boreal and austral seasonal regimes), and matches patterns of genetic structure previously observed in other forest plant species. Our results illustrate independent speciation between two species that live in specific and obligate symbiosis and suggest that a tension zone may separate lineages of several central African forest plants near the thermal equator.

AbstractColorectal cancer (CRC) is the second leading cause of cancer‐related deaths worldwide. However, a biomarker for a sensitive and simple diagnostic test and highly effective target therapy of CRC is still clinically unavailable. This study is to investigate the evidence and significance of plasma GPC1 positive exosomes as a biomarker of CRC. Results showed that GPC1+ exosomes were successfully isolated from tissues and plasma. The percentage of GPC1+ exosomes and the GPC1 protein expression in exosomes from tumour tissues and plasma of CRC patients before surgical treatment was significantly elevated compared to that in the peritumoural tissues and the plasma of healthy controls. miR‐96‐5p and miR‐149 expression in tumour tissues and plasma of CRC patients as well as in the GPC1+ exosomes from CRC patients were significantly decreased compared to that in the peritumoural tissues and the plasma of healthy controls. Two months after surgical treatment, levels of all tested markers significantly normalized. Overexpression of miR‐96‐5p and miR‐149 significantly decreased GPC1 expression in HT‐29 and HCT‐116 cells, xenograft tumours, plasma in mice bearing HT‐29 and HCT‐116 tumours, and the secretion of GPC1+ exosomes from the HT‐29 and HCT‐116 cells and xenograft tumours. Overexpression of miR‐96‐5p and miR‐149 significantly decreased cell viability and increased cell apoptosis in HT‐29 and HCT‐116 cells, and inhibited the growth of xenograft HT‐29 and HCT‐116 tumours. In conclusion, the increased plasma GPC1+ exosomes and reduced plasma miR‐96‐5p and miR‐149 expression are specific markers for the diagnosis of CRC and targets for the therapy of CRC.
Print media representations of UK Accident and Emergency treatment targets: Winter 2014–2015
Authors: Grant Aimee , Hoyle Louise 
Published: February 2017

Aims and ObjectivesTo undertake an analysis of UK national daily newspaper coverage of accident and emergency treatment targets, in order to understand whether the media could be seen to be creating a scandal.BackgroundEmergency department treatment targets have become common in developed countries. In the UK, hospitals are required to treat and discharge patients within four hours, and statistics are published daily. Breaches of targets are regularly reported by the UK print media.DesignExploratory research of tabloid newspaper articles that reported on four‐hour treatment targets in the UK during a seven‐month period over the winter of 2014–2015 (n = 1,317). An interpretivist thematic approach was used during analysis.ResultsThe main “problem” identified by newspapers was the failure to meet the target, rather than negative effects on patient care (where they existed). Proposed solutions were diverse. Many articles did not describe who was to blame for the failure.ConclusionWe conclude that the media created a feeling of scandal, and hypothesise that this is related to political reasons and the availability of data on a daily basis.Relevance to clinical practiceIt is important for nursing staff to understand the influence of the media on patients and how stories are reported.

Aims and objectivesTo observe the extent to which a nursing discharge plan is effective in promoting therapeutic adherence and improving patient satisfaction with their treatment based on information interventions provided by nursing staff, direct hospital medication distribution and follow‐up telephone calls.BackgroundPatient adherence is a fundamental requirement for the treatment of chronic diseases. Among psychiatric patients, adherence to the prescribed course of treatment allows patients to keep the symptoms of their disease under control, allowing for improvements in the management of their condition, minimising the risks of relapse and reducing the number of hospitalisations.DesignThis study uses a prospective correlational design.MethodsThe Morisky Medication Adherence Scale, the Satisfaction with Information about Medicine Scale and the General Satisfaction Questionnaire were used.ResultsOf the 135 patients enrolled in the study, 57% of the sample was female, and, on average, patients were aged 33 years. About 72.9% were unmarried, and 88.1% were educated at less than high school level. This study showed that patients who received more information on their health status and on what would be done for them after their hospitalisation had a higher adherence to treatment. In addition, patients who were more satisfied with the nursing care provided had a higher rate of adherence to their treatment plan.ConclusionsThe interpersonal and educational nursing intervention improves adherence to a treatment plan by allowing patients to express themselves not only as individuals who rely on health care but also as protagonists able to effectively manage their disease and to empower themselves by acquiring disease management skills.Relevance to clinical practiceA patient–nurse communication programme could help to analyse the individual patient circumstances that might become barriers to adherence and to apply nursing interventions that promote better patient adherence.

Aims and ObjectivesTo explore the lived experiences of patients with haematological malignancies who had been in protective isolation during their hospital stay for autologous haematopoietic stem cell transplantation.BackgroundAlthough protective isolation aims to benefit patients’ health by preventing infection, it could also imply harmful psycho‐social implications for patients, such as loneliness.DesignA descriptive phenomenological study was conducted in an Italian university hospital.MethodsNine patients with haematological malignancies who had been in protective isolation for autologous haematopoietic stem cell transplantation were enrolled. They were interviewed during their weekly ambulatory visits, which are usually carried out up to 100 days post‐transplant, and asked about their stay in isolation. Giorgi's method of analysis was used to describe the experience of protective isolation from the patient’ perspective.ResultsEight themes emerged: isolation is a defence, threats from which patients have to defend themselves, rules for defence, the burden of the defence, external strategies for defence, inner strengths for defence, defending loved ones and outcomes of the defence. The general structure was expressed as a defence from suffering.ConclusionsWhile fighting a hard battle against cancer, informants largely accepted the strict isolation measure and represented it as a shield for an effective defence.Relevance to clinical practiceNurses should provide emotional and social support to help patients feel like active fighters and strengthen their strategies for an effective defence from suffering.
The Macroeconomic Effects of Shocks to Large Banks’ Capital
Authors: Mésonnier Jean‐Stéphane , Stevanovic Dalibor 
Published: February 2017

AbstractWe propose a simple approach to quantifying the macroeconomic effects of shocks to large banks’ leverage. We first estimate a standard dynamic model of leverage targeting at the bank level and use it to derive an aggregate measure of the economic capital buffer of large US bank holding corporations. We then evaluate the response of key macro variables to a shock to this aggregate bank capital buffer using standard monetary VAR models. We find that shocks to the capital of large US banks explain a substantial share of the variance of credit to firms and real activity.
A Factor Analytical Approach to Price Discovery
Authors: Westerlund Joakim , Reese Simon , Narayan Paresh 
Published: February 2017

AbstractExisting econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The current paper takes these shortcomings as a starting point to develop a factor analytical approach that makes use of the cross‐sectional variation of the data, yet is very user‐friendly in that it does not involve any identifying restrictions or obstacles to inference.

AbstractFreely nodulating soybean genotypes vary in their phosphorus (P) uptake and P‐use efficiency (PUE) in low‐P soils. Understanding the genetic basis of these genotypes’ performance is essential for effective breeding. To study the inheritance ofPUE, we conducted crosses using two high‐PUEgenotypes, two moderate‐PUEgenotypes and two inefficient‐PUEgenotypes, and obtained F1, F2,BC1andBC2populations. The inheritance ofPUEwas evaluated using a randomized complete block design. A generation mean analysis of phenotypic data showed thatPUEwas heritable, with complex inheritance patterns and the presence of additive, dominance and epistatic gene effects. Seed P, shoot P, root P, P‐incorporation efficiency andPUEwere largely quantitatively inherited traits. There were dominance, additive × additive and dominance × dominance gene effects onPUE, grain yield, shoot dry weight, 100‐seed weight, root dry weight and shoot dry matter per unit P for populations grown under low‐P conditions. Dominance effects were generally greater than additive effects onPUE‐related indices. ThesePUEindices can be used to select P‐efficient soybean genotypes from segregating populations.
Parasites, nutrition, immune responses and biology of metabolic tissues
Authors: Shea‐Donohue T. , Qin B. , Smith A. 
Published: February 2017

SummaryNutritional immunology, immunometabolism and identification of novel immunotherapeutic targets are areas of active investigation in parasitology. There is a well‐documented crosstalk among immune cells and cells in metabolically active tissues that is important for homeostasis. The numbers and function of these cells are altered by obesity leading to inflammation. A variety of helminths spend some part of their life cycle in the gastrointestinal tract and even entirely enteral nematode infections exert beneficial effects on glucose and lipid metabolism. The foundation of this review is the ability of enteric nematode infections to improve obesity‐induced type 2 diabetes and the metabolic syndrome, which are significant health issues in developed areas. It considers the impact of nutrition and specific nutritional deficiencies, which are occur in both undeveloped and developed areas, on the host's ability mount a protective immune response against parasitic nematodes. There are a number of proposed mechanisms by which parasitic nematodes can impact metabolism including effects gastrointestinal hormones, altering epithelial function and changing the number and/or phenotype of immune cells in metabolic tissues. Nematodes can also exert their beneficial effects through Th2 cytokines that activate the transcription factor STAT6, which upregulates genes that regulate glucose and lipid metabolism.

SUMMARYObjectivesTo assess the awareness and attitudes related to blood transfusion safety among blood donors from the Autonomous Province (AP) Vojvodina, Republic of Serbia.BackgroundBlood donors are at the initial point of safe blood transfusion systems. The active participation of blood donors in the selection process contributes to increasing the safety of blood transfusions and reduces potential risks for the recipients.Materials and MethodsThis cross‐sectional survey included 1191 blood donors from AP Vojvodina. The awareness and attitudes regarding safe blood supply were measured as 5‐point scales of agreement/disagreement with statements on a Likert scale. The data were analysed using non‐parametric methods by frequency modalities.ResultsMale blood donors, the youngest age group (18–20 years), those who donate blood for the first time and those with a lower educational level showed the lowest awareness of, and the most negative attitudes about, blood safety.ConclusionsThe study found that there is a small but, for the safety of transfusion, significant number of blood donors who do not have a positive attitude or awareness of their own impact on safe transfusion therapy and who are not discovered during standard selection procedures.

Published: February 2017

Abstract
Systematic studies of Siberia and the Far East started at the beginning of the twentieth century and Poles played an important part in these studies. These Poles included those who had been deported after the overthrow of insurrections, as well as voyagers, explorers and industrialists – all of whom were attracted to this region by their nature and cupidity. There were many geologists among these people, with interests ranging from ethnography to zoology and botany. They also carried out meteorological and topographical measurements. This paper discusses some of the well-known explorers, including P. Czekanowski, J. Czerski, K. Bohdanowicz and J. Morozewicz, and also less famous explorers, such as A. Giedrojć, L. Barszczewski, B. Grąbczewski, L. Jaczewski, K. Grochowski and S. Doktorowicz-Hrebnicki. All of these explorers were also brilliant researchers and distinguished themselves in the exploration of the territories east of the Ural Mountains. After Poland regained its independence, some of them also contributed to the development of the geological sciences in Poland.
Tsunami landfalls in the Maltese archipelago: reconciling the historical record with geomorphological evidence
Authors: Mottershead Derek N. , Bray Malcolm J. , Soar Philip J. 
Published: February 2017

Abstract
The Maltese Islands lie in the middle of the tsunamigenic Mediterranean domain, around whose margins and islands evidence of historical tsunami landfall has been increasingly recognized in recent years. Critical review of historical evidence of events in 1693 and 1908 indicates extremely modest tsunami impacts. In marked contrast, though, recently discovered geomorphological evidence summarized herein suggests that Malta's coastlines have been overwashed up to elevations of >20 m above sea level by an exceptional event. A new perspective is provided by a review of the central Mediterranean context within which the Maltese evidence is located. Recent advances in understanding the Holocene sequence forming the floor of the Mediterranean Sea present a new stratigraphic and temporal framework within which to elucidate tsunami history. Within 100 km of Malta, terrestrial stratigraphy on Sicily also provides supporting evidence of tsunami impact. Review of these advances suggests that the exceptional event required to emplace the most extreme sedimentary and geomorphological signatures on and around Malta is likely to have had a far-field origin. The currently available circumstantial evidence points strongly towards a probability that the AD 365 earthquake and tsunami were responsible. This, in turn, enables critical reassessment of the exposure of Malta to tsunami hazard.
