Analysis of an iterative scheme for approximate regulation for nonlinear systems
Authors: Aulisa E. , Gilliam D.S. , Pathiranage T.W.
Published: March 2018

This paper concerns the analysis of an iterative scheme delivering approximate control laws for the tracking regulation problems for nonlinear systems. The procedure can be applied to finite‐ and infinite‐dimensional systems, and the underlying methodology derives from the geometric methods, which have been developed for both linear and nonlinear systems. In the nonlinear case, the main tool is the center manifold theorem. Indeed, in the geometric methodology, under the assumption that the signals to be tracked are generated by a finite‐dimensional exo‐system, the desired control is obtained by solving a pair of operator equations called the regulator equations. In this paper, we extend the concept of regulator equations to what we refer to as the dynamic regulator equations. Just as it is generally quite difficult to solve the regulator equations, it can be equally difficult to solve the dynamic regulator equations. As the authors have already shown in the linear case, a straightforward attempt to solve the dynamic regulator equations leads to a singular system, which can be regularized to obtain an iterative scheme that provides approximate control laws that provide accurate tracking with very a small tracking error after only a couple of iterations. In this paper, we generalize the iterative scheme to nonlinear systems and provide error estimates for the first 3 iterations. Both finite‐ and infinite‐dimensional examples are given to validate the estimates. We comment that the method has also been applied to a wide range of nonlinear distributed parameter examples described in the references.

Published: March 2018

During the 1950s–1960s, the Merkys river basin, the largest protected area of Lithuania, underwent severe anthropogenic regulations. Within the Baltic States, the genetic diversity of Phalaris arundinacea populations is unknown and how they might be affected by anthropogenic activities such as river regulation. The objectives of this study were to compare molecular parameters (SSRs or microsatellite loci) within and among populations from natural river fragments with populations from regulated river parts. Study populations have greater genetic diversity within, rather than among, populations. The upstream portion of the Merkys basin populations had lower genetic diversity compared with further downstream. The mean number of polymorphic SSR loci was lower for populations from regulated parts of the river basin compared with natural ones. Main principle coordinate analysis revealed populations of regulated rivers at marginal positions. Bayesian clustering showed that current populations are admixtures of 3 distinct genetic groups, based on STRUCTURE analysis (K = 3 groupings) in geographic subdivisions of (a) downstream populations (Varėnė, Verseka, Upper Grūda, Lower Grūda, Upper Merkys, Lower Merkys), (b) upstream populations (Upper Šalčia, Beržė, Lower Šalčia, Visinčia, Lower Šaltykščia, Nedilė), and (c) the 2 regulated sites in the distinct geographic area of Taurupis and Upper Šaltykščia. P. arundinacea in the Merkys river basin does not all belong to a single, random‐mating population encompassing its tributaries or among populations across its geographic scales. In several instances, river regulation might impair the genetic diversity of P. arundinacea populations.
Fault‐based test generation for regular expressions by mutation
Authors: Arcaini Paolo , Gargantini Angelo , Riccobene Elvinia
Published: March 2018

Regular expressions are used to characterize sets of strings (ie, languages) using a pattern‐based syntax. They are applied in different contexts as, for example, data validation in Web forms. However, writing a regular expression that exactly captures the desired set of strings could be particularly difficult, and techniques are sought to validate regular expressions or test their use in applications. A common means to regular expression validation and testing is the generation of a set of labelled strings (ie, strings together with their evaluation).

We here propose a fault‐based approach for generating strings usable as tests for regular expressions. We define some fault classes representing mistakes that could be made when writing a regular expression, and we introduce the notion of distinguishing string, ie, a string that is able to expose a fault. Given a regular expression, our approach generates a test suite composed of distinguishing strings that are able to detect possible faults in the regular expression. We present different versions of the approach, which provide different results in terms of test suite size and generation time. Experiments show that the proposed approach can generate compact test suites and that, using suitable optimizations, the generation time is reasonable.

Exploiting the proposed fault classes, we use the notion of mutation score to assess the ability of a generic set of strings in exposing possible faults contained in the regular expression under test. A comparison with other test generation tools in terms of mutation score, size, and generation time shows the advantages and limits of our approach.
Mindfulness Among Genetic Counselors Is Associated with Increased Empathy and Work Engagement and Decreased Burnout and Compassion Fatigue
Authors: Silver Julia , Caleshu Colleen , Casson‐Parkin Sylvie , Ormond Kelly
Published: March 2018

Genetic counselors experience high rates of compassion fatigue and an elevated risk for burnout, both of which can negatively impact patient care and retention in the profession. In other healthcare professions, mindfulness training has been successfully used to address similar negative psychological sequelae and to bolster empathy, which is the foundation of our counseling work. We aimed to assess associations between mindfulness and key professional variables, including burnout, compassion fatigue, work engagement, and empathy. Data were collected via an anonymous, online survey that included validated measures of mindfulness and these key professional variables. The survey was completed by 441 genetic counselors involved in direct patient care. Half of the respondents (50.1%) reported engaging in yoga, meditation, and/or breathing exercises. Mindfulness was positively correlated with work engagement (r = 0.24, p < 0.001) and empathy (as measured through four subscales: perspective taking (r = 0.15,p = 0.002), empathic concern (r = 0.11,p = 0.03), fantasy (r = − 0.11,p = 0.03) and personal distress (r = − 0.15,p = 0.001)). Mindfulness was negatively correlated with compassion fatigue (r = − 0.48,p < 0.001) and burnout (r = − 0.50,p < 0.001). Given these findings, mindfulness training may be a valuable addition to graduate and continuing education for genetic counselors. The integration of mindfulness into the genetic counseling field will likely improve professional morale and well‐being, while promoting workforce retention and bolstering the relational and counseling aspects of our clinical work.
Long-term effect of prenatal exposure to malnutrition on risk of schizophrenia in adulthood: Evidence from the Chinese famine of 1959–1961

Published: March 2018

Background:

Schizophrenia is a common major mental disorder and prenatal nutritional deficiency may increase its risk. We aimed to investigate long-term impact of prenatal exposure to malnutrition on risk of schizophrenia in adulthood using the Chinese famine of 1959–1961 as a natural experiment.

Methods:

We obtained data from the Second National Sample Survey on Disability implemented in 31 provinces in 2006, and restricted our analysis to 387,093 individuals born from 1956 to 1965. Schizophrenia was ascertained by psychiatrists based on the International Statistical Classification of Diseases, Tenth Revision. Famine severity was defined as cohort size shrinkage index. The famine effect on adult schizophrenia was estimated by difference-in-difference models, established by examining the variations of famine exposure across birth cohorts.

Results:

Compared with the reference cohort of 1965, famine cohorts (1959–1962) had significantly higher odds (OR: 1.84; 95% CI: 1.13, 3.00; P = 0.014) of schizophrenia in the rural population. After adjusting for multiple covariates, this association remained significant (OR: 1.82; 95% CI: 1.11, 2.98; P = 0.018). We did not observe statistically significant differences in odds of schizophrenia among famine cohorts compared with the reference cohort in the urban population.

Conclusions:

Prenatal malnutrition exposure has a detrimental impact on risk of schizophrenia in adulthood in the rural population. Further studies were needed to investigate corresponding mechanisms on this topic.
Altered anatomical connections of associative and limbic cortico-basal-ganglia circuits in obsessive-compulsive disorder
Authors: Haynes William I.A. , Clair Anne-Hélène , Fernandez-Vidal Sara , Gholipour Bahar , Morgiève Margot , Mallet Luc
Published: March 2018

Background:

Current neurocognitive models suppose dysfunctions of associative and limbic cortico-basal ganglia circuits to be at the core of obsessive-compulsive disorder (OCD). As little is known about the state of underlying anatomical connections, we investigated whether these connections were reduced and/or not properly organised in OCD patients compared to control.

Methods:

Diffusion magnetic resonance images were obtained in 37 OCD patients with predominant checking symptoms and 37 matched healthy controls. We developed indices to characterise the quantity (spatial extent and density) and the organisation (topography and segregation) of 24 anatomical connections between associative and limbic cortical (anterior cingulate, dorsolateral prefrontal, orbitofrontal cortices and the frontal pole), and subcortical (caudate nucleus, putamen and thalamus) areas in each hemisphere.

Results:

Associative and limbic cortico-basal-ganglia connections were reduced in OCD patients compared to controls: 19/24 connections had a reduced subcortical spatial extent, 9/24 had a reduced density. Moreover, while the general topography was conserved, the different cortical projection fields in the striatum and thalamus were hyper-segregated in OCD patients compared to controls.

Conclusion:

These quantitative and qualitative differences of anatomical connections go beyond the current model of a reduced cortical control of automatic behaviour stored in the basal ganglia. The hyper-segregation in OCD could also impair the integration of cortical information in the thalamus and striatum and distort the subsequent behavioural selection process. This provides new working hypotheses for functional and behavioural studies on OCD.
Measuring costs of community mental health care in Italy: A prevalence-based study
Authors: Senese F. , Rucci P. , Fantini M.P. , Gibertoni D. , Semrov E. , Nassisi M. , Messina R. , Travaglini C.
Published: March 2018

Background:

Information on individual mental healthcare costs and utilization patterns in Italy is scant. We analysed the use and the annual costs of community mental health services (MHS) in an Italian local health authority (LHA). Our aims are to compare the characteristics of patients in the top decile of costs with those of the remaining 90%, and to investigate the demographic and clinical determinants of costs.

Methods:

This retrospective study is based on administrative data of adult patients with at least one contact with MHS in 2013. Costs of services were estimated using a microcosting method. We defined as high cost (HC) those patients whose community mental health services costs place them in the top decile of the cost distribution. The predictors of costs were investigated using multiple linear regression.

Results:

The overall costs borne for 7601 patients were 17 million €, with HC accounting for 87% of costs and 73% of services. Compared with the rest of the patients, HC were younger, more likely to be male, to have a diagnosis of psychosis, and longer and more intensive MHS utilization. In multiple linear regression, younger age, longer duration of contact with MHS, psychosis, bipolar disorder, personality disorder, depression, dementia and Italian citizenship accounted for 20.7% of cost variance.

Conclusion:

Direct mental health costs are concentrated among a small fraction of patients who receive intensive socio-rehabilitation in community services. One limitation includes the unavailability of hospital costs. Our methodology is replicable and useful for national and cross-national benchmarking.
Sovereign credit and political survival in democracies
Authors: DiGiuseppe Matthew , Shea Patrick E.
Published: March 2018

Models of distributive politics often assume that fixed budgets constrain the efforts of incumbents to retain power. Yet, significant variation exists in politicians' abilities to push distributive costs forward by funding current fiscal policy through sovereign borrowing. This article theorizes how and when variation in sovereign credit access influences the central goal of democratic incumbents: political survival. Credit allows incumbents to reward supporters without immediately extracting domestic revenue. Excessive borrowing, however, risks higher interest rates or possible market exclusion. Considering sovereign borrowing's benefits and costs, we argue that the marginal effect of credit access on political survival is greatest for those incumbents that require other parties to implement fiscal policy. An analysis of incumbent party tenure in seventy-one democracies from 1977–2007 demonstrates that affordable sovereign finance is associated with longer tenures under divided government but has no significant effect on survival under unified governments.
Ectopic pregnancy outcomes in patients discharged from the emergency department
Authors: Hawrylyshyn Krista , McLeod Shelley L. , Thomas Jackie , Varner Catherine
Published: March 2018

Objective

The objective of this study was to determine the proportion of women who had a ruptured ectopic pregnancy after being discharged from the emergency department (ED) where ectopic pregnancy had not yet been excluded.

Methods

This was a retrospective chart review of pregnant (<12-week gestational age) women discharged home from an academic tertiary care ED with a diagnosis of ectopic pregnancy, rule-out ectopic pregnancy, or pregnancy of unknown location over a 7-year period.

Results

Of the 550 included patients, 83 (15.1%) had a viable pregnancy, 94 (17.1%) had a spontaneous or missed abortion, 230 (41.8%) had an ectopic pregnancy, 72 (13.1%) had unknown outcomes, and 71 (12.9%) had other outcomes that included therapeutic abortion, molar pregnancy, or resolution of βHCG with no location documented. Of the 230 ectopic pregnancies, 42 (7.6%) underwent expectant management, 131 (23.8%) were managed medically with methotrexate, 29 (5.3%) were managed with surgical intervention, and 28 (5.1%) patients had a ruptured ectopic pregnancy after their index ED visit. Of the 550 included patients, 221 (40.2%) did not have a transvaginal ultrasound during their index ED visit, and 73 (33.0%) were subsequently diagnosed with an ectopic pregnancy.

Conclusion

These results may be useful for ED physicians counselling women with symptomatic early pregnancies about the risk of ectopic pregnancy after they are discharged from the ED.
Creation of a national emergency medicine enhanced competency directory for residency training

Published: March 2018

Canadian emergency medicine Royal College residency training allows for pursuing extra training in enhanced competency areas. A wealth of enhanced competency training opportunities exist nationally. However, the search for the right fit is a challenging one because there is no centralized resource that catalogues all of these opportunities. A working group of the Canadian Association of Emergency Physicians (CAEP) Resident Section was assembled in 2016 to create a freely accessible and comprehensive directory of Canadian enhanced competency areas. The working group used stakeholder surveys (of residents, recent graduates, and faculty members), social media engagement, and program website searches. Information was collated into the first edition of a national enhanced competency directory, which is available at no cost at http://caep.ca/sites/caep.ca/files/enhancedcompdoc.pdf. Limitations include the scope defined by the working group and survey responses. A biannual update is also incorporated into the CAEP Resident Section portfolio to ensure it remains up-to-date.
Automated Translation of Clinical Parameters in Evaluating Acute Radiation Injury: Results From a Mass Casualty Exercise
Authors: Dant James T. , Reeves Glen , Stricklin Daniela
Published: March 2018

Objective

A radiological disaster could result in a large number of patients potentially exposed to harmful levels of radiation. Currently, early triage of patients for radiation exposure relies heavily on a clinical evaluation of signs and symptoms. However, detailed clinical assessment takes significant time and requires specialized training to accurately interpret the results.

Methods

During planning of a recent exercise, SMEs estimated that it would take up to 15 minutes per patient. Patient load would quickly overwhelm the number of qualified clinicians providing treatment. In this exercise organized by the NATO RTG HFM 222, we examined using automated translation of clinical data to facilitate clinic evaluations. We used two triage evaluation approaches; REAC/TS and METREPOL. These approaches allowed us to translate tabulated clinical data, first into categorical data for grouping patients, and then into recommendations for follow-up diagnostics and care.

Results

The organizers provided clinical evaluations of 191 case studies that were estimated to require up to 50 total hours for completion. However, using our application, we were able to evaluate all cases in less than 2 minutes.

Conclusion

This study clearly demonstrates the need for automated tools to help translate clinical data for effective patient triage after a nuclear or radiological incident. (Disaster Med Public Health Preparedness. 2018;12:569–573)

The Zika virus was largely unknown to many health care systems before the outbreak of 2015. The unique public health threat posed by the Zika virus and the evolving understanding of its pathology required continuous communication between a health care delivery system and a local public health department. By leveraging an existing relationship, NYC Health+Hospitals worked closely with New York City Department of Health and Mental Hygiene to ensure that Zika-related processes and procedures within NYC Health+Hospitals facilities aligned with the most current Zika virus guidance. Support given by the public health department included prenatal clinical and laboratory support and the sharing of data on NYC Health+Hospitals Zika virus screening and testing rates, thus enabling this health care delivery system to make informed decisions and practices. The close coordination, collaboration, and communication between the health care delivery system and the local public health department examined in this article demonstrate the importance of working together to combat a complex public health emergency and how this relationship can serve as a guide for other jurisdictions to optimize collaboration between external partners during major outbreaks, emerging threats, and disasters that affect public health.

Hegel and Arguments for Natural Kind Essentialism
Authors: Knappik Franz
Published: March 2018

Natural Kind Essentialism (NKE) is the view that the objects of sciences like physics, chemistry and biology fall into natural kinds, and that such kinds have essences—sets of properties possession of which is necessary and sufficient for kind-membership. Since Putnam and Kripke brought NKE back onto the philosophical agenda, it has found many advocates. But comparatively little attention has been paid to the question of how this view can be positively motivated. After illustrating the current need for an argument for NKE through critical discussions of Putnam’s, Kripke’s and Ellis’s arguments for NKE, this article aims to show that Hegel offers the resources for an original argument for the view. This argument works by deriving metaphysical implications from an account of what it means to understand an explanandum.
Mapping Boarding School Opportunities for Aboriginal Students from the Central Land Council Region of Northern Territory

Published: March 2018

The 2014 Wilson review of Indigenous Education in the Northern Territory recommended boarding school models as the preferred secondary education option for very remote Aboriginal students. This study considers boarding uptake by Aboriginal students from the Central Land Council region of the Northern Territory. An examination of boarding programs available to Aboriginal students in this region found that scholarship access is largely determined by socioeducational advantage and the perceived social stability of the family and student. To increase access and participation in boarding, more flexible funding assistance programs are needed. An expanded role for brokering could also increase retention and completion rates. Ultimately, more investment is also required in remote community schools, and in the development of ‘both ways’ capital if the social and educational aspirations of young Aboriginal students and their families in this region are to be realised through a boarding school model.
Warm-based basal sediment entrainment and far-field Pleistocene origin evidenced in central Transantarctic blue ice through stable isotopes and internal structures
Authors: GRALY JOSEPH A. , LICHT KATHY J. , KASSAB CHRISTINE M. , BIRD BROXTON W. , KAPLAN MICHAEL R.
Published: March 2018

Stable isotopes of water (δ18O and δ2H) were measured in the debris-laden ice underlying an Antarctic blue ice moraine, and in adjoining Law Glacier in the central Transantarctic Mountains. Air bubble content and morphology were assessed in shallow ice core samples. Stable isotope measurements plot either on the meteoric waterline or are enriched from it. The data cluster in two groups: the ice underlying the moraine has a δ2H:δ18O slope of 5.35 ± 0.92; ice from adjoining portions of Law Glacier has a slope of 6.69 ± 1.39. This enrichment pattern suggests the moraine's underlying blue ice entrained sediment through refreezing processes acting in an open system. Glaciological conditions favorable to warm-based sediment entrainment occur 30–50 km upstream. Basal melting and refreezing are further evidenced by abundant vapor figures formed from internal melting of the ice crystals. Both the moraine ice and Law Glacier are sufficiently depleted of heavy isotopes that their ice cannot be sourced locally, but instead must be derived from far-field interior regions of the higher polar plateau. Modeled ice flow speeds suggest the ice must be at least 80 ka old, with Law Glacier's ice possibly dating to OIS 5 and moraine ice older still.
Controls on rapid supraglacial lake drainage in West Greenland: an Exploratory Data Analysis approach
Authors: WILLIAMSON ANDREW G. , WILLIS IAN C. , ARNOLD NEIL S. , BANWELL ALISON F.
Published: March 2018

The controls on rapid surface lake drainage on the Greenland ice sheet (GrIS) remain uncertain, making it challenging to incorporate lake drainage into models of GrIS hydrology, and so to determine the ice-dynamic impact of meltwater reaching the ice-sheet bed. Here, we first use a lake area and volume tracking algorithm to identify rapidly draining lakes within West Greenland during summer 2014. Second, we derive hydrological, morphological, glaciological and surface-mass-balance data for various factors that may influence rapid lake drainage. Third, these factors are used within Exploratory Data Analysis to examine existing hypotheses for rapid lake drainage. This involves testing for statistical differences between the rapidly and non-rapidly draining lake types, as well as examining associations between lake size and the potential controlling factors. This study shows that the two lake types are statistically indistinguishable for almost all factors investigated, except lake area. Thus, we are unable to recommend an empirically supported, deterministic alternative to the fracture area threshold parameter for modelling rapid lake drainage within existing surface-hydrology models of the GrIS. However, if improved remotely sensed datasets (e.g. ice-velocity maps, climate model outputs) were included in future research, it may be possible to detect the causes of rapid drainage.

Published: March 2018

Objectives

According to a recent study, ratings on the Psychotic Depression Assessment Scale (PDAS) obtained via a dedicated semi-structured interview are valid measures of the severity of psychotic depression. This study aimed to further test the validity, scalability and responsiveness of the PDAS in older adults using independent ratings on the Clinical Global Impression Scale – Severity (CGI-S) and the Montgomery-Asberg Depression Rating Scale (MADRS) as references.

Methods

Ratings were performed at admission and discharge at two old age psychiatric wards in Flanders, Belgium. In total, 62 older adults (mean age: 74.3 years) with psychotic depression were included. The PDAS was rated by trained nurses using the semi-structured PDAS interview. Senior psychiatrists scored the participants on the CGI-S. Psychologists or experienced nurses rated participants on the MADRS. Clinical validity was assessed by correlating the PDAS total scores with CGI-S ratings and MADRS total scores. Mokken analysis was performed to assess the scalability of the PDAS. Responsiveness was assessed by comparing the proportion of participants in remission (PDAS total score <8 at study baseline and endpoint).

Results

The Spearman correlation coefficients were 0.76 and 0.79 for the PDAS versus CGI-S and PDAS versus MADRS, respectively. The Mokken analysis yielded a Loevinger coefficient of 0.46, which is indicative of scalability. At admission, no participants met the PDAS remission criterion. At discharge, 54% (95% confidence interval: 47%–60%) of the patients met this criterion.

Conclusion

The PDAS appears to be a clinically valid, scalable and responsive measure of the severity of psychotic depression in older adults.
Projections for Future Radiocarbon Content in Dissolved Inorganic Carbon in Hardwater Lakes: A Retrospective Approach
Authors: Blattmann Thomas M , Wessels Martin , McIntyre Cameron P , Eglinton Timothy I
Published: March 2018

Inland water bodies contain significant amounts of carbon in the form of dissolved inorganic carbon (DIC) derived from a mixture of modern atmospheric and pre-aged sources, which needs to be considered in radiocarbon-based dating and natural isotope tracer studies. While reservoir effects in hardwater lakes are generally considered to be constant through time, a comparison of recent and historical DI14C data from 2013 and 1969 for Lake Constance reveals that this is not a valid assumption. We hypothesize that changes in atmospheric carbon contributions to lake water DIC have taken place due to anthropogenically forced eutrophication in the 20th century. A return to more oligotrophic conditions in the lake led to reoxygenation and enhanced terrigenous organic matter remineralization, contributing to lake water DIC. Such comparisons using DI14C measurements from different points in time enable nonlinear changes in lake water DIC source and signature to be disentangled from concurrent anthropogenically induced changes in atmospheric 14C. In the future, coeval changes in lake dynamics due to climate change are expected to further perturb these balances. Depending on the scenario, Lake Constance DI14C is projected to decrease from the 2013 measured value of 0.856 Fm to 0.54–0.62 Fm by the end of the century.
Choosing the Velvet Glove: Women Voters, Ambivalent Sexism, and Vote Choice in 2016
Authors: Frasure-Yokley Lorrie
Published: March 2018

This paper examines the extent to which ambivalent sexism toward women influenced vote choice among American women during the 2016 Presidential election. I examine how this varied between white women and women of color. The 2016 American National Election Study (ANES) features several measures from the Ambivalent Sexism Inventory (ASI)—a scale developed by Glick and Fiske (1996) to assess sexist attitudes toward women. An index of these measures is used to examine the extent to which ambivalent sexist attitudes influenced women's vote choice for Donald Trump, controlling for racial resentment, partisanship, attitudes toward immigrants, economic anxiety, and socio-demographics. On the one hand, my findings indicate that ambivalent sexism was a powerful influence on women's Presidential vote choice in 2016, controlling for other factors. However, this finding, based on a model ofall women votersis misleading, once an intersectional approach is undertaken. Once the data are disaggregated by gender and race, white women's political behavior proves very different than women of color. Among white women, ambivalent sexist views positively and significantly predicts vote choice for Trump, controlling for all other factors. However, for women of color, this relationship was negative and posed no statistical significant relationship to voting for Trump. Scholarship in gender and politics that does not account for group differences in race/ethnicity may present misleading results, which are either underestimated or overestimated.
Differential growth performance and intestinal immune gene expression in diverse genetic lines of growing chickens fed a high concentration of supplemental phytase
Authors: Jiang S. Q. , Lamont S. J. , Persia M. E.
Published: March 2018

The objective of the current experiment was to determine the effects of high-concentration phytase (5000 FTU/kg) feeding to diverse lines of chickens fed phosphorus (P) adequate maize–soybean meal diets (4.5 g/kg non-phytate P) on the performance and intestinal immune function. Performance was measured for outbred broiler (Ross 308) and inbred Fayoumi lines over 0–21 days, and duodenum and ileum were harvested for the determination of mucin-2, interleukin (IL)-1βand IgA mRNA by quantitative reverse transcription polymerase chain reaction. Over the 0–7-day period, there was a significant line × diet interaction, as high phytase supplementation increased broiler average daily gain (ADG), but had no effect on Fayoumi ADG. Treatment of diets with phytase increased expression of the mucin-2 gene in the duodenum mucosa. There were significant interactions between line and age, and line, diet and age on duodenal expression of the IL-1βgene as phytase supplementation of the broiler line reduced IL-1βin comparison to control fed broilers without change in the Fayoumi line. Overall, the addition of a high concentration of phytase to broilers fed adequate concentrations of non-phytate P resulted in improved growth performance early with a reduction in this effect over time. Mucosal mucin-2 expression was increased with high-concentration phytase feeding across both lines, but IL-1βmRNA expression was reduced in the duodenum of broilers fed high concentrations of phytase, suggesting that the increased performance noted might be related to decreased inflammation.
Market Reaction to Bank Liquidity Regulation
Authors: Bruno Brunella , Onali Enrico , Schaeck Klaus
Published: March 2018

We measure market reactions to announcements concerning liquidity regulation, a key innovation in the Basel framework. Our initial results show that liquidity regulation attracts negative abnormal returns. However, the price responses are less pronounced when coinciding announcements concerning capital regulation are backed out, suggesting that markets do not consider liquidity regulation to be binding. Bank- and country-specific characteristics also matter. Liquid balance sheets and high charter values increase abnormal returns whereas smaller long-term funding mismatches reduce abnormal returns. Banks located in countries with large government debt and tight interbank conditions or with prior domestic liquidity regulation display lower abnormal returns.
Building verbs in Chuj: Consequences for the nature of roots
Authors: COON JESSICA
Published: March 2018

This paper offers an in-depth look at roots and verb stem morphology in Chuj (Mayan) in order to address a larger question: when it comes to the formation of verb stems, what information is contributed by the root, and what is contributed by the functional heads? I show first that roots in Chuj are not acategorical in the strict sense (cf. Borer 2005), but must be grouped into classes based on their stem-forming possibilities. Root class does not map directly to surface lexical category, but does determine which functional heads (i.e. valence morphology) may merge with the root. Second, I show that while the introduction of the external argument, along with clausal licensing and agreement generally, are all governed by higher functional heads, the presence or absence of aninternalargument is dictated by the root. Specifically, I show that transitive roots in Chuj always combine with an internal argument, whether it be (i) a full DP, (ii) a bare pseudo-incorporated NP, or (iii) an implicit object in an antipassive. In the spirit of work such as Levinson (2007, 2014), I connect this to the semantic type of the root; root class reflects semantic type, and semantic type affects the root’s combinatorial properties. This work also contributes to the discussion of how valence morphology operates. In line with works such as Alexiadou, Anagnostopoulou & Schäfer (2006), I argue that valence morphology applies directly to roots, rather than to some ‘inherent valence’ of a verb.
Electrostatic stability of electron–positron plasmas in dipole geometry
Authors: Mishchenko Alexey , Plunk Gabriel G. , Helander Per
Published: March 2018

The electrostatic stability of electron–positron plasmas is investigated in the point-dipole and Z-pinch limits of dipole geometry. The kinetic dispersion relation for sub-bounce-frequency instabilities is derived and solved. For the zero-Debye-length case, the stability diagram is found to exhibit singular behaviour. However, when the Debye length is non-zero, a fluid mode appears, which resolves the observed singularity, and also demonstrates that both the temperature and density gradients can drive instability. It is concluded that a finite Debye length is necessary to determine the stability boundaries in parameter space. Landau damping is investigated at scales sufficiently smaller than the Debye length, where instability is absent.
Parameters of tongue shape of /n/ and /l/ in Basque

Published: March 2018

This paper presents an experimental articulatory characterisation of lateral /l/ and nasal /n/ in Basque, using MRI midsagittal images. In order to assess previous observations of retroflexion or velarisation in these consonants in Basque, a battery of articulatory parameters is used which can be directly measured on the images. This set of parameters, focused on the description of the tongue shape and position, permits a fine-grained characterisation of the articulation of the two consonants under study, indicating the possible existence of a double articulation pattern in /l/ and, less clearly, in /n/. The results help to compensate for the lack of experimental descriptions on the articulation of Basque.

The genus Acanthogobius of gobiioid fish has been reported for six species from East Asia, and inhabits estuarine and coastal waters. Within this genus, Acanthogobius insularis is an endangered and endemic goby in the Amami-oshima and Okinawa-jima Islands, southern Japan, and its range is restricted to the lowermost course of a few river basins. Basic knowledge on this species is scarce in spite of its vulnerable conservation status. The purpose of this study was to elucidate the life history of A. insularis. Monthly sampling was conducted at five stations in the Taiho River, Okinawa-jima Island, from November 2014 to November 2015. Monthly standard length (SL) distributions were unimodal except in April during the recruiting period, suggesting that A. insularis is an annual species. Analysis of the gonadosomatic index and histological observations of the ovaries revealed that this species spawns from January to May. The beginning of the spawning season seems to be related to a decline in water temperature in December. Growth rates appeared to be lower from April to December and higher in winter months. From monthly collections, A. insularis was found to move upstream with growth, and gather at spawning grounds during the reproductive season. Acanthogobius insularis might be threatened by increasing water temperature due to climate change, since low water temperatures appear to be important for their reproduction and growth. Moreover, habitat diversity, from tidal flats for recruiting grounds to upstream sites with cobbles for spawning, is needed to complete their life cycle, and should be conserved.

Understanding the impact of livestock on native wildlife is of increasing conservation relevance. For the Vulnerable snow leopard Panthera uncia, wild prey reduction, intensifying human–wildlife conflicts and retaliatory killings are severe threats potentially exacerbated by the presence of livestock. Elucidating patterns of co-occurrence of snow leopards, wild ungulate prey, and livestock, can be used to assess the compatibility of pastoralism with conservation. We used camera trapping to study the interactions of livestock, Siberian ibex Capra sibirica and snow leopards in a national park in the Altai mountains, Mongolia. We obtained 494 detections of wild mammals and 912 of domestic ungulates, dogs and humans. Snow leopards and Siberian ibex were recorded 14 and 33 times, respectively. Co-occurrence modelling showed that livestock had a higher estimated occupancy (0.65) than ibex, whose occupancy was lower in the presence of livestock (0.11) than in its absence (0.34–0.35 depending on scenarios modelled). Snow leopard occupancy did not appear to be affected by the presence of livestock or ibex but the robustness of such inference was limited by uncertainty around the estimates. Although our sampling at presumed snow leopard passing sites may have led to fewer ibex detections, results indicate that livestock may displace wild ungulates, but may not directly affect the occurrence of snow leopards. Snow leopards could still be threatened by livestock, as overstocking can trigger human–carnivore conflicts and hamper the conservation of large carnivores. Further research is needed to assess the generality and strength of our results.
What accounts for poor functioning in people with schizophrenia: a re-evaluation of the contributions of neurocognitive v. attitudinal and motivational factors

Background

Neurocognitive deficits are often seen as core features of schizophrenia, and as primary determinants of poor functioning. Yet, our clinical observations suggest that individuals who score within the impaired range on standardized tests can reliably perform better in complex real-world situations, especially when performance is embedded within a positive socio-affective context.

Methods

We analyzed literature on the influence of non-neurocognitive factors on test performance in order to clarify their contributions.

Results

We identified seven non-neurocognitive factors that significantly contribute to neurocognitive test performance: avolition, dysfunctional attitudes, effort, stress, negative emotions, asociality, and disorganized symptoms. We then proposed an alternative model based on dysfunctional (e.g. defeatist) attitudes and their consequences for motivation and sustained task engagement. We demonstrated that these factors account for substantial variance in negative symptoms, neurocognitive test performance, and functional outcomes. We then demonstrated that recovery-oriented cognitive therapy – which is derived from this alternative model and primarily targets dysfunctional beliefs – has been successful in the treatment of low functioning individuals with schizophrenia.

Conclusion

The contributions of neurocognitive impairments to poor real-world functioning in people with schizophrenia may be overstated in the literature, and may even be limited relative to non-neurocognitive factors. We offer suggestions for further research to more precisely quantify the contributions of attitudinal/motivation v. neurocognitive factors in schizophrenia.
Polygenic risk for schizophrenia and season of birth within the UK Biobank cohort

Published: March 2018

Background

There is strong evidence that people born in winter and in spring have a small increased risk of schizophrenia. As this ‘season of birth’ effect underpins some of the most influential hypotheses concerning potentially modifiable risk exposures, it is important to exclude other possible explanations for the phenomenon.

Methods

Here we sought to determine whether the season of birth effect reflects gene-environment confounding rather than a pathogenic process indexing environmental exposure. We directly measured, in 136 538 participants from the UK Biobank (UKBB), the burdens of common schizophrenia risk alleles and of copy number variants known to increase the risk for the disorder, and tested whether these were correlated with a season of birth.

Results

Neither genetic measure was associated with season or month of birth within the UKBB sample.

Conclusions

As our study was highly powered to detect small effects, we conclude that the season of birth effect in schizophrenia reflects a true pathogenic effect of environmental exposure.
Living arrangement preferences and realities for elderly Chinese: implications for subjective wellbeing
Authors: CHEN TAICHANG
Published: March 2018

This article investigates the determinants of preference for intergenerational co-residence and examines the effects of living arrangement concordance (i.e.having a match between preference and reality) on the subjective wellbeing (SWB) of older Chinese. Data were derived from the China Health and Retirement Longitudinal Study (CHARLS) national baseline conducted in 2011. This allows for two different measures of the affective approach to SWB: depression and happiness. This article found living arrangement preference is indicative of need, cultural norms and current living arrangement experiences. The results support the hypothesis of discrepancy theories that having living arrangement concordance improves older parents’ SWB (i.e.depressive symptoms and happiness). In addition, the previously predictive effects of the actual living arrangement on SWB lost significance when actual living arrangement and concordance were added simultaneously. Living in a preferred arrangement appears to be more important than living in a traditional arrangement from the point of view of older adults’ SWB. Programmes designed to improve wellbeing in later life should not assume that there is a one-size-fits-all model for all; instead, older people should be given more choices of living arrangements.

The aim of this study is to explore how community-dwelling older people with cognitive problems and their care-givers (dyads) perceive their own social participation, how care-givers evaluate the social participation of the people they care for and what factors they perceive as influential. In this qualitative study, we performed 13 semi-structured, in-depth interviews with dyads who participated in the Social Fitness Programme. We used content analysis to analyse the interviews thematically. Social participation perceptions include changes over time and a discrepancy in perspectives. All the people with cognitive problems and most care-givers perceived a decreased social participation. Most people with cognitive problems answered that they were satisfied, in contrast to most care-givers who were dissatisfied with the decreased social participation of the people they cared for. Analysing the influencing factors resulted in five themes: behavioural, physical, social environmental, physical environmental and activity-related. People with cognitive problems and their care-givers displayed a discrepancy in social participation perspectives. This becomes a major dilemma, especially for younger care-givers. A key element is a sometimes deliberate choice of people with cognitive problems to refrain from social participation to protect themselves from the consequences of cognitive problems and from encounters with others. This highlights the dynamics of social participation as an interaction between personal factors and the social and physical environment in which social participation occurs.
