Malongitubus: a possible pterobranch hemichordate from the early Cambrian of South China
Authors: Hu Shixue , Erdtmann Bernd-D. , Steiner Michael , Zhang Yuandong , Zhao Fangchen , Zhang Zhiliang , Han Jian
Published: December 2017

Malongitubus kuangshanensis Hu, 2005 from the early Cambrian Chengjiang Lagerstätte of China is redescribed as a pterobranch and provides the best evidence to demonstrate that hemichordates were present as early as Cambrian Stage 3. Interpretation of this taxon as a hemichordate is based on the morphology of the branched colony and the presence of resistant inner threads consistent with the remains of an internal stolon system. The presence of fusellar rings in the colonial tubes cannot be unambiguously proven for Malongitubus, probably due to early decay and later diagenetic replacement of the thin organic material of the tubarium, although weak annulations are still discernible in parts of the tubes. The description of M. kuangshanensis is revised according to new observations of previously reported specimens and recently collected additional new material. Malongitubus appears similar in most features to Dalyia racemata Walcott, 1919 from the Cambrian Stage 5 Burgess Shale, but can be distinguished by the existence of disc-like thickenings at the bases of tubarium branching points in the latter species. Both species occur in rare mass-occurrence layers with preserved fragmentary individuals of different decay stages, with stolon remains preserved as the most durable structures. Benthic pterobranchs may have occurred in some early Cambrian shallow marine communities in dense accumulations and provided firm substrates and shelter for other benthic metazoans as secondary tierers.
Exhibiting Good Health: Public Health Exhibitions in London, 1948–71
Authors: Mold Alex
Published: December 2017

This article examines the changing nature of public health services and their relationship with the public in post-war Britain by an analysis of the exhibitions mounted by Medical Officers of Health (MOsH) in London. Focusing on the period 1948–71, the article explores a time when public health practice, and the problems it faced, were in flux. A decline in infectious disease and an increase in chronic conditions linked to lifestyle required a new role for public health services. Exhibitions were one of several methods that MOsH used to inform the public about dangers to their health, but also to persuade them to change their behaviour. The exhibition, though, offers a unique insight into the relationship between public health authorities and the public, as exhibitions brought MOsH into direct contact with people. It is suggested that in the MOsH exhibitions we can find signs of a new relationship between public health practitioners and the public. Whilst elements of the pre-war, often moralistic ideology of public health services could still be detected, there is also evidence of a more nuanced, responsive dynamic between practitioners and the people. By the end of the 1960s, ‘the public’ was increasingly being thought of as a collection of ‘publics’, including individuals, target groups and vocal respondents.
Boyish Mannerisms and Womanly Coquetry: Patients with the Diagnosis ofTransvestitismusin the Helsinki Psychiatric Clinic in Finland, 1954–68
Authors: Parhi Katariina
Published: December 2017

This article examines the case files of patients diagnosed withTransvestitismus[transvestism] in the Psychiatric Clinic of the Helsinki University Central Hospital in the years 1954–68. These individuals did not only want to cross-dress, but also had a strong feeling of being of a different sex from their assigned one. The scientific concept of transsexuality had begun to take form, and this knowledge reached Finland in phases. The case files of the transvestism patients show that they were highly aware of their condition and were very capable of describing it, even if they had no medical name for it. Psychiatrists were willing to engage in dialogue with the patients, and did not treat them as passive objects of study. Although some patients felt that they had been helped, many left the institution as frustrated, angered or desperate as before. They had sought medical help in the hope of having their bodies altered to correspond to their identity, but the Clinic psychiatrists insisted on seeing the problem in psychiatric terms and did not recommend surgical or hormonal treatments in most cases. This attitude would gradually change over the course of the 1970s and 1980s.
Lechebnaia pedagogika: The Concept and Practice of Therapy in Russian Defectology, c. 1880–1936
Authors: Byford Andy
Published: December 2017

Therapy is not simply a domain or form of medical practice, but also a metaphor for and a performance of medicine, of its functions and status, of its distinctive mode of action upon the world. This article examines medical treatment or therapy (in Russianlechenie), as concept and practice, in what came to be known in Russia as defectology (defektologiia) – the discipline and occupation concerned with the study and care of children with developmental pathologies, disabilities and special needs. Defectology formed an impure, occupationally ambiguous, therapeutic field, which emerged between different types of expertise in the niche populated by children considered ‘difficult to cure’, ‘difficult to teach’, and ‘difficult to discipline’. The article follows the multiple genealogy of defectological therapeutics in the medical, pedagogical and juridical domains, across the late tsarist and early Soviet eras. It argues that the distinctiveness of defectological therapeutics emerged from the tensions between its biomedical, sociopedagogical and moral-juridical framings, resulting in ambiguous hybrid forms, in which medical treatment strategically interlaced with education or upbringing, on the one hand, and moral correction, on the other.

Published: December 2017

HESS J1614–518 and HESS J1616–508 are two tera-electron volt γ-ray sources that are not firmly associated with any known counterparts at other wavelengths. We investigate the distribution of interstellar medium towards the tera-electron volt γ-ray sources using results from a 7-mm-wavelength Mopra study, the Mopra Southern Galactic Plane CO Survey, the Millimetre Astronomer’s Legacy Team-45 GHz survey and [C i] data from the HEAT telescope. Data in the CO(1–0) transition lines reveal diffuse gas overlapping the two tera-electron volt sources at several velocities along the line of sight, while observations in the CS(1–0) transition line reveal several interesting dense gas features. To account for the diffuse atomic gas, archival H i data was taken from the Southern Galactic Plane Survey. The observations reveal gas components with masses ~103 to 105 M⊙ and with densities ~102 to 103 cm−3 overlapping the two tera-electron volt sources. Several origin scenarios potentially associated with the tera-electron volt γ-ray sources are discussed in light of the distribution of the local interstellar medium. We find no strong convincing evidence linking any counterpart with HESS J1614–518 or HESS J1616–508.
Radicalization
Authors: Malthaner Stefan
Published: December 2017

Over the course of the past decade, “radicalization” has become prevalent as an analytical paradigm to interpret and explain phenomena of political violence, notably in research on jihadist terrorism and Western “foreign fighters” in Syria and Iraq. Thereby, while to some extent opening up new avenues of investigation, the concept also significantly re-shaped the way in which phenomena of political violence were analyzed and explained, focusing analytical attention on processes of cognitive and ideological transformation, mainly at the individual level. The purpose of this article is to examine some of the main strands of development in recent research on radicalization, with reference to and within the context of broader sociological research on political violence as well as reviewing critical debates and recently emerging sub-fields of investigation.
Agrarian Change, Industrialization and Geopolitics
Authors: Duzgun Eren
Published: December 2017

This article takes issue with the common view that the early Turkish Republic (1920-1940) followed a “special” route to modernity characterized by “state capitalism.” It argues that such a view, rooted in theSonderwegparadigm, obscures the historical-comparative specificity of Turkish state formation, leading to problematic conclusions about the character of Turkish modernization. Based on insights derived from Karl Polanyi’s notion of “economistic fallacy” and Political Marxism’s conception of capitalism, I offer a new interpretation of the early Republican project in Turkey, which, in turn, provides a deeper understanding of the social content, tempo and multi-linearity of world historical development.

Micronutrient status in middle childhood and age at menarche: results from the Bogotá School Children Cohort
Authors: Villamor Eduardo , Marín Constanza , Mora-Plazas Mercedes , Oliveros Henry
Published: December 2017

Childhood intake of animal foods is associated with age at first menstrual period (menarche). It is unknown whether the micronutrients present in these foods could explain this association. Our objective was to investigate the associations of micronutrient status biomarkers in middle childhood with age at menarche. We quantified circulating Hb, ferritin, mean corpuscular volume, Zn, vitamin B12, erythrocyte folate and retinol in 1464 pre-menarcheal girls aged 5–12 years in Bogotá, Colombia, and followed them for a median 5·7 years for the occurrence and date of menarche. We estimated median age at menarche and hazard ratios (HR) with 95 % CI by levels of each biomarker with use of Kaplan–Meier survival probabilities and Cox regression, respectively. Median age at menarche was 12·4 years. Middle childhood Hb was inversely related to age at menarche whereas plasma ferritin was positively associated with this outcome in a linear manner. HR of menarche for every 1sdof Hb (11 g/l) and ferritin (23·2 µg/l) were 1·11 (95 % CI 1·04, 1·18;P=0·001) and 0·94 (95 % CI 0·88, 0·99;P=0·02), respectively, after adjustment for baseline age, C-reactive protein concentration, maternal age at menarche and parity and socioeconomic status. The association with ferritin was stronger in girls aged 9–10 years at baseline. Additional adjustment for baseline height- and BMI-for-age did not change the results. We conclude that higher Fe status in middle childhood is related to later age at menarche whereas Hb concentrations are inversely associated with age at onset of menses.
Networks and Social Influence in European Legislative Politics
Authors: Malang Thomas , Brandenberger Laurence , Leifeld Philip
Published: December 2017

The Treaty of Lisbon strengthened the role of national parliaments in the European Union. It introduced an ‘early warning system’, granting parliamentary chambers the right to reject legislative proposals by the European Commission. Previous studies assumed independence between the decisions of parliaments to reject a legislative proposal. We apply recent advances in inferential network analysis and argue that parliamentary vetoes are better explained by conceptualizing parliaments’ veto actions as a temporal network. Network effects can be observed along the dimension of party families. Based on a new permutation approach, we find that parliaments with similar party majorities influence each other over the course of the decision period (‘social influence’), rather than basing their decisions independently on joint prior partisanship (‘selection’).

Published: December 2017

The bird cherry-oat aphid Rhopalosiphum padi (L.) is one of the most important wheat pests with polyphagia and autumn migrants. And, chemosensory genes were thought to play a key role in insect searching their hosts, food and mate. However, a systematic identification of the chemosensory genes in this pest has not been reported. Thus, in this study, we identified 14 odorant-binding proteins, nine chemosensory proteins, one sensory neuron membrane protein, 15 odorant receptors, 19 gustatory receptors and 16 ionotropic receptors from R. padi transcriptomes with a significantly similarity (E-value < 10−5) to known chemosensory genes in Acyrthosiphon pisum and Aphis gossypii. In addition, real-time quantitative polymerase chain reaction (RT-qPCR) was employed to determine the expression profiles of obtained genes. Among these obtained genes, we selected 23 chemosensory genes to analyze their expression patterns in different tissues, wing morphs and host plants. We found that except RpOBP1, RpOBP3, RpOBP4 and RpOBP5, the rest of the selected genes were highly expressed in the head with antennae compared with body without head and antennae. Besides that, the stimulation and depression of chemosensory genes by plant switch indicated that chemosensory genes might be involved in the plant suitability assessment. These results not only provide insights for the potential roles of chemosensory genes in plant search and perception of R. padi but also provide initial background information for the further research on the molecular mechanism of the polyphagia and autumn migrants of it. Furthermore, these chemosensory genes are also the candidate targets for pest management control in future.
Effects of insecticides chlorpyrifos, emamectin benzoate and fipronil on Spodoptera litura might be mediated by OBPs and CSPs
Authors: Lin X. , Jiang Y. , Zhang L. , Cai Y.
Published: December 2017

Spodoptera litura is a widespread polyphagous insect pest that can develop resistance and cross-resistance to insecticides, making it difficult to control. Insecticide exposure has previously been linked with induction of specific olfactory-related proteins, including some chemosensory proteins (CSPs) and odorant-binding proteins (OPBs), which may disrupt detection of environmental factors and reduce fitness. However, functional evidence supporting insecticide and OBPs/CSPs mediation remains unknown. Here we fed male S. litura moths with sucrose water containing one of three insecticides, chlorpyrifos, emamectin benzoate or fipronil, and used real-time quantitative polymerase chain reaction and RNAi to investigate OBPs and CSPs expression and their correlations with survival. Chlorpyrifos and emamectin benzoate increased expression of 78% of OBPs, plus 63 and 56% of CSP genes, respectively, indicating a major impact on these gene families. RNAi knockdown of SlituCSP18, followed by feeding with chlorpyrifos or fipronil, decreased survival rates of male moths significantly compared with controls. Survival rate also decreased significantly with the downregulation of SlituOBP9 followed by feeding with chlorpyrifos. Thus, although these three insecticides had different effects on OBP and CSP gene expression, we hypothesize that SlituOBPs and SlituCSPs might mediate their effects by increasing their expression levels to improve survival. Moreover, the differential response of S. litura male moths to the three insecticides indicated the potential specificity of chlorpyrifos affect SlituCSP18 and SlituOBP9 expression.
Tactical Diversity in Militant Violence
Authors: Horowitz Michael C. , Perkoski Evan , Potter Philip B.K.
Published: December 2017

Militant groups, like all organizations, carefully consider the tactics and strategies that they employ. We assess why some militant organizations diversify into multiple tactics while others limit themselves to just one or a few. This is an important puzzle because militant organizations that employ multiple approaches to violence are more likely to stretch state defenses, achieve tactical success, and threaten state security. We theorize that militant organizations respond to external pressure by diversifying their tactics to ensure their survival and continued relevance, and that the primary sources of such pressure are government repression and interorganizational competition. We find consistent support for these propositions in tests of both the Global Terrorism Database (GTD) and Minorities at Risk Organizational Behavior (MAROB) data sets. We bolster these findings with an additional specification that employs ethnic fractionalization in the first stage of a multi-process recursive model. These findings are relevant not only for academic research but for policy as well. While it is difficult for countries to anticipate the character of future tactical choices, they may be able to anticipate which groups will most readily diversify and thereby complicate counterterrorism efforts.
“A Shooting Star of Conservatism”: George S. Benson, the National Education Program and the “Radical Right”
Authors: MAXWELL ROBBIE
Published: December 2017

This article reassesses the so-called “Radical Right,” a political phenomenon that emerged in the early 1960s and was especially associated with a controversial conservative anticommunism. The article argues that the National Education Program (NEP), which was founded in Arkansas in 1943, made an important and unheralded contribution to the Radical Right and the consequential activism it stimulated in pockets of the South and Southwest. The article also, however, argues that the Radical Right ultimately made a less significant contribution to the subsequent resurgence of conservatism than has often been suggested. Conventional wisdom maintains that it aligned religious, economic, and racial concerns under the umbrella of anticommunism and thereby fostered a distinctly modern conservatism; the NEP demonstrates that these concerns were not as disparate or marginal prior to the 1960s as this narrative assumes. The Radical Right's fixation with communist subversion also often diluted efforts to promote conservative principles – the NEP became less focussed on advancing ideological principles during this period. After the mid-1950s, moreover, the declining legitimacy of McCarthyite politics outwith parts of the South and Southwest undermined the NEP's wider efforts, precipitated the organization's terminal decline, and ensured that the Radical Right created problems for the broader conservative movement.
Political Uncertainty and IPO Activity: Evidence from U.S. Gubernatorial Elections
Authors: Çolak Gönül , Durnev Art , Qian Yiming
Published: December 2017

We analyze initial public offering (IPO) activity under political uncertainty surrounding gubernatorial elections in the United States. There are fewer IPOs originating from a state when it is scheduled to have an election. To establish identification, we develop a neighboring-states method that uses bordering states without elections as a control group. The dampening effect of elections on IPO activity is stronger for firms with more concentrated businesses in their home states, firms that are more dependent on government contracts (particularly state contracts), and harder-to-value firms. This dampening effect is related to lower IPO offer prices (hence, higher costs of capital) during election years.
Sustainable diet policy development: implications of multi-criteria and other approaches, 2008–2017
Authors: Lang Tim , Mason Pamela
Published: December 2017

The objective of the present paper is to draw lessons from policy development on sustainable diets. It considers the emergence of sustainable diets as a policy issue and reviews the environmental challenge to nutrition science as to what a ‘good’ diet is for contemporary policy. It explores the variations in how sustainable diets have been approached by policy-makers. The paper considers how international United Nations and European Union (EU) policy engagement now centres on the 2015 Sustainable Development Goals and Paris Climate Change Accord, which require changes across food systems. The paper outlines national sustainable diet policy in various countries: Australia, Brazil, France, the Netherlands, Qatar, Sweden, UK and USA. While no overarching common framework for sustainable diets has appeared, a policy typology of lessons for sustainable diets is proposed, differentiating (a) orientation and focus, (b) engagement styles and (c) modes of leadership. The paper considers the particularly tortuous rise and fall of UK governmental interest in sustainable diet advice. Initial engagement in the 2000s turned to disengagement in the 2010s, yet some advice has emerged. The 2016 referendum to leave the EU has created a new period of policy uncertainty for the UK food system. This might marginalise attempts to generate sustainable diet advice, but could also be an opportunity for sustainable diets to be a goal for a sustainable UK food system. The role of nutritionists and other food science professions will be significant in this period of policy flux.
Neurocognitive dysfunctioning and the impact of comorbid depression and anxiety in patients with somatic symptom and related disorders: a cross-sectional clinical study
Authors: de Vroege Lars , Timmermans Anique , Kop Willem J. , van der Feltz-Cornelis Christina M.
Published: December 2017

Background

The prevalence and severity of neurocognitive dysfunctioning of patients with somatic symptom and related disorders (SSRD) is unknown. Furthermore, the influence of comorbid depression and anxiety has not been evaluated. This study examines neurocognitive dysfunctioning of patients with SSRD and explores if comorbid depression and anxiety is associated with specific neurocognitive dysfunctioning.

Methods

Cross-sectional study with consecutive patients suffering from SSRD visiting an outpatient specialty mental health care Centre of Excellence for SSRD. Extensive neuropsychological assessment and assessment of depression and anxiety symptom levels using the Patient-Health-Questionnaire-9 and General Anxiety Disorder questionnaire-7 were performed at intake. Multivariate analysis was performed.

Results

The study sample consisted of 201 SSRD patients, with a mean age of 43 years (Standard deviation = 13) years; 37.8% were male. Neurocognitive dysfunction in the domains information processing speed, sustained and divided attention, working memory, verbal and visual memory were reported, compared with normative data. Comorbid depression and anxiety occurred frequently within the sample (75.1% and 65.7%, respectively). Neurocognitive dysfunctioning was worse in patients suffering from comorbid depression [multivariateF(7,161) = 2.839,p= 0.008] but not in patients with comorbid anxiety.

Conclusions

Poor neurocognitive performance of patients with SSRD is common and worsens in case of comorbid depression. This may explain treatment dropout of patients with SSRD from neurocognitive behavioral therapy. Research on novel interventions is needed targeting neurocognitive functioning of patients with SSRD, particularly those with comorbid depression.
Secular trends in the prevalence of major and subthreshold depression among 55–64-year olds over 20 years
Authors: Jeuring Hans W. , Comijs Hannie C. , Deeg Dorly J. H. , Stek Max L. , Huisman Martijn , Beekman Aartjan T. F.
Published: December 2017

Background

Studying secular trends in the exposure to risk and protective factors of depression and whether these trends are associated with secular trends in the prevalence of depression is important to estimate future healthcare demands and to identify targets for prevention.

Methods

Three birth cohorts of 55–64-year olds from the population-based Longitudinal Aging Study Amsterdam were examined using identical methods in 1992 (n = 944), 2002 (n = 964) and 2012 (n = 957). A two-stage screening design was used to identify subthreshold depression (SUBD) and major depressive disorder (MDD). Multinomial logistic regression analyses were used to identify secular trends in depression prevalence and to identify factors from the biopsychosocial domains of functioning that were associated with these trends.

Results

Compared with 1992, MDD became more prevalent in 2002 (OR 1.90, 95% CI 1.10–3.28, p = 0.022) and 2012 (OR 1.80, 95% CI 1.03–3.14, p = 0.039). This was largely attributable to an increase in the prevalence of chronic diseases and functional limitations. Socioeconomic and psychosocial improvements, including an increase in labor market participation, social support and mastery, hampered MDD rates to rise more and were also associated with a 32% decline of SUBD-rates in 2012 as compared with 2002 (OR 0.68, 95% CI 0.48–0.96, p = 0.03).

Conclusions

Among late middle-aged adults, there is a substantial net increase of MDD, which is associated with deteriorating physical health. If morbidity and disability continue to increase, a further expansion of MDD rates may be expected. Improving socioeconomic and psychosocial conditions may benefit public health, as these factors were protective against a higher prevalence of both MDD and SUBD.
The incidence of very late-onset psychotic disorders: a systematic review and meta-analysis, 1960–2016
Authors: Stafford Jean , Howard Robert , Kirkbride James B.
Published: December 2017

A substantial subset of people with psychotic disorders are first diagnosed in old age, yet little is known about the epidemiology of very late-onset schizophrenia-like psychosis. We investigated the incidence of affective and non-affective psychotic disorders in those aged 65 and above, and examined variation related to potential risk factors via systematic literature review. We searched PubMed, PsychInfo, Web of Science and bibliographies and directly contacted authors to obtain citations published between 1960 and 2016 containing (derivable) incidence data. Cases were those diagnosed with non-organic psychotic disorders after age 65. Findings were presented narratively, and random-effects meta-analyses were used to obtain pooled incidence rates. From 5687 citations, 41 met inclusion criteria. The pooled incidence of: affective psychoses was 30.9 per 100 000 person-years at risk (100 kpy) [95% confidence interval (CI) 11.5–83.4; I2 = 0.99], and schizophrenia was 7.5 per 100 kpy (95% CI 6.2–9.1; I2 = 0.99), with some evidence of higher schizophrenia rates in women [odds ratio (OR) = 1.6; 95% CI 1.0–2.5, p = 0.05]. We found narrative evidence of increasing incidence rates of non-affective psychoses with age, and higher rates amongst migrants than baseline populations, but no evidence that incidence varied by study quality or case ascertainment period (quality OR = 1.04; 95% CI 0.74–1.48; time period OR = 1.00; 95% CI 0.95–1.05). Substantial heterogeneity in the incidence of very late-onset schizophrenia-like psychoses was observed. No identified studies examined possible risk factors which may account for such variation, including socio-economic status, sensory impairment, traumatic life events, or social isolation.
Policy, plans and pathways: the ‘crisis’ transition to post-parental care for people ageing with intellectual disabilities in rural Australian carescapes
Authors: GARNHAM BRIDGET , BRYANT LIA , RAMCHARAN PAUL , YU NILAN , ADAMS VALERIE
Published: December 2017

The concurrent ageing of parental care-givers and people with intellectual disabilities is driving academic and social welfare concern for a post-parental care ‘crisis’. The ‘crisis’ typically pertains to a transition from primary care in the family home precipitated by the death or incapacity of older parents without a pre-planned pathway to post-parental care. This crisis is amplified in rural communities given low service engagement with families and a deficit of disability-supported accommodation and services. Academics, service providers and policy makers have responded through a problematisation of post-parental care planning. This focus continues to normalise informal care, burdens families with responsibility for planning, and diverts attention from structural deficits in the socio-political carescape. This paper attends to the Australian policy landscape in which long-term care-giving for families living with intellectual disability is enmeshed. It contends that the dyadic and didactic model of informal long-term care has profound implications for social service support and post-parental care planning. Problematisation of carers’ ‘need’ to relinquish primary care and for people with intellectual disabilities to transition to independent and supported living is necessary to unsettle the dominant policy and service discourse around the provision of services to sustain informal care-giving. Innovation is then needed to forge pathways of support for families in rural communities planning on continuing, transitioning and transforming care arrangements across the lifespan.

Published: December 2017

In this paper, the results of an experimental investigation of dust formation in a pulsed plasma accelerator, which is formed due to the interaction of a pulsed plasma flow with the candidate material of the thermonuclear reactor, are presented. Dynamic and optical properties of a pulsed plasma flow are considered. The results of the synergetic analysis by the Raman spectrometer of the target surface after irradiation with plasma are also presented. It was revealed that after interaction with the plasma, the surface of the graphite target becomes amorphous. Materials with fractal surfaces, similar to the materials formed in tokamaks under the action of erosion, were obtained experimentally. Using a high-speed camera Phantom v2512 video shooting of the plasma beam was carried out, during which it was revealed that the pulsed plasma beam has a speed of about 23 km/s.
Discrete-time control of bilateral teleoperation systems: a review
Authors: Ghavifekr Amir Aminzadeh , Ghiasi Amir Rikhtehgar , Badamchizadeh Mohammad Ali
Published: December 2017

The possibility of operating in remote environments using teleoperation systems has been considered widely in the control literature. This paper presents a review on the discrete-time teleoperation systems, including issues such as stability, passivity and time delays. Using discrete-time methods for a master-slave teleoperation system can simplify control implementation. Varieties of control schemes have been proposed for these systems and major concerns such as passivity, stability and transparency have been studied. Recently, unreliable communication networks affected by packet loss and variable transmission delays have been received much attention. Thus, it is worth considering discrete-time theories for bilateral teleoperation architectures, which are formulated on the same lines as the continuous-time systems. Despite the extensive amount of researches concerning continuous-time teleoperation systems, only a few papers have been published on the analysis and controller design for discrete bilateral forms. This paper takes into account the challenges for the discrete structure of bilateral teleoperation systems and notifies the recent contributions in this area. The effect of sampling time on the stability-transparency trade-off and the task performance is taken into consideration in this review. These studies can help to design guidelines to have better transparency and stable teleoperation systems.
Mill's Metaethical Non-cognitivism
Authors: ZUK PETER
Published: December 2017

In section I, I lay out key components of my favoured non-cognitivist interpretation of Mill's metaethics. In section II, I respond to several objections to this style of interpretation posed by Christopher Macleod. In section III, I respond to David Brink's treatment of the well-known ‘competent judges’ passage in Mill'sUtilitarianism. I argue that important difficulties face both Brink'sevidential interpretationand the rivalconstitutive interpretationthat he proposes but rejects. I opt for a third interpretative option that I call thepsychological interpretation. This interpretation makes sense of otherwise difficult aspects of chapter IV ofUtilitarianism. In section IV, I offer some reasons for rejecting Nicholas Drake's claim that Mill is ultimately best characterized as a Humean constructivist. If we accept Drake's suggestion that Mill's non-cognitivism is compatible with his being a constructivist, I argue, we should view Mill as putting forward a distinctively Millian form of constructivism rather than a Humean one.
Bacteria from Fildes Peninsula carry class 1 integrons and antibiotic resistance genes in conjugative plasmids

Published: December 2017

A total of 63 psychrotolerant bacteria exhibiting resistance to various antibiotics, such as ampicillin, streptomycin and/or trimethoprim, were isolated from diverse sites varying in terms of human influence, from obvious presence to probable absence, on Fildes Peninsula (King George Island, South Shetland Islands). The presence of class 1 integrons in some of these antibiotic resistant isolates was further determined. Plasmids from two isolates (HP19 and CN11) were transferred toEscherichia coliDH5α by conjugation. Sequence analysis of the plasmid from the HP19 isolate exhibited high similarity (~99%) to plasmid p34998-210.894kb ofEnterobacter hormaecheisubsp.steigerwaltiiof clinical origin and confirmed the presence of adfrA14cassette in a class 1 integron context. 16S rRNA gene sequence analysis of five of these psychrotolerant isolates indicated similarity with environmental bacteria previously identified asEnterobacterspecies. Together, these results confirm that there may be no pristine niches for antibiotic resistance gene dissemination.

Published: December 2017

In this study,in situand erratic samples from George V Coast (East Antarctica) and southern Eyre Peninsula (Australia) have been used to characterize the microstructural, pressure–temperature and geochronological record of upper amphibolite and granulite facies polymetamorphism in the Mawson Continent to provide insight into the spatial distribution of reworking and the subice geology of the Mawson Continent. Monazite U-Pb data shows thatin situsamples from the George V Coast record exclusively 2450–2400 Ma ages, whereas most erratic samples from glacial moraines at Cape Denison and the Red Banks Charnockite record only 1720–1690 Ma ages, consistent with known ages of the Sleaford and Kimban events, respectively. Phase equilibria forward modelling reveals considerable overlap of the thermal character of these two events. Samples with unimodal 1720–1690 Ma Kimban ages reflect either formation after the Sleaford event or complete metamorphic overprinting. Rocks recording only 2450–2400 Ma ages were unaffected by the younger Kimban event, perhaps as a result of unreactive rock compositions inherited from the Sleaford event. Our results suggest the subice geology of the Mawson Continent is a pre-Sleaford-aged terrane with a cover sequence reworked during the Kimban event.

Painted rock art occurs throughout the islands of the Western Pacific and has previously been argued to have motif and design elements in common, indicating that it was created within the context of a shared symbolic system. Here we report five new painted rock-art sites from Kisar Island in eastern Indonesia and investigate the commonalities between this art and the painted art corpus in Timor-Leste, the independent nation that forms the eastern part of the neighbouring island of Timor. We examine the motifs in the Kisar art and suggest that, rather than being Neolithic in age, some of the figurative motifs more likely have a Metal Age origin, which in this region places them within the last 2500 years.

Thirty angiosperm species in 20 families, collected in Nam Kading National Protected Area, are recorded in Laos for the first time. Because the flora of Nam Kading is rich in endemic species, the area represents one of the core sites of plant biodiversity in Laos. To elucidate the plant diversity accurately, further intensive floristic surveys are required.

Atrial septal defect is one of the most common CHD. The pathogenesis of atrial septal defect still remains unknown.Cx43is the most prevalent connexin in the mammalian heart during development. Its genetic variants can cause several CHD. The aim of our study was to investigate the association of genetic variations of theCx43with sporadic atrial septal defect. A total of 450 paediatric patients were recruited, including 150 cases with atrial septal defect and 300 healthy controls. The promoter region ofCx43was analysed by sequencing after polymerase chain reaction. All data were analysed by using the Statistic Package for Social Science 19.0 software. The frequency of the single nucleotide polymorphism rs2071166 was significantly higher in atrial septal defect cases than in healthy controls. The CC genotype at rs2071166 site inCx43was correlated with an increased risk for atrial septal defect (p<0.0001, odds ratio=3.891, 95% confidence interval 1.948–7.772) and the C allele was positively correlated with atrial septal defect (p=0.007, odds ratio=1.567, 95% confidence interval 1.129–2.175). In conclusion, our results confirmed that rs2071166 inCx43may be relevant with an increased atrial septal defect risk.

An estimated 15 million children die or are crippled annually by treatable or preventable heart disease in low- and middle-income countries. Global efforts to reduce under-5 mortality have focused on reducing death from communicable diseases in low- and middle-income countries with little to no attention focusing on paediatric CHD and acquired heart disease. Lack of awareness of CHD and acquired heart disease, access to care, poor healthcare infrastructure, competing health priorities, and a critical shortage of specialists are important reasons why paediatric heart disease has not been addressed in low resourced settings. Non-governmental organisations have taken the lead to address these challenges. This review describes the global burden of paediatric heart disease and strategies to improve the quality of care for paediatric heart disease. These strategies would improve outcomes for children with heart disease.
Management of undernutrition and failure to thrive in children with congenital heart disease in low- and middle-income countries

Published: December 2017

Poor growth with underweight for age, decreased length/height for age, and underweight-for-height are all relatively common in children with CHD. The underlying causes of this failure to thrive may be multifactorial, including innate growth potential, severity of cardiac disease, increased energy requirements, decreased nutritional intake, malabsorption, and poor utilisation of absorbed nutrition. These factors are particularly common and severe in low- and middle-income countries.

Although nutrition should be carefully assessed in all patients, failure of growth is not a contraindication to surgical repair, and patients should receive surgical repair where indicated as soon as possible.

Close attention should be paid to nutritional support – primarily enteral feeding, with particular use of breast milk in infancy – in the perioperative period and in the paediatric ICU. This nutritional support requires specific attention and allocation of resources, including appropriately skilled personnel.

Thereafter, it is essential to monitor growth and development and to identify causes for failure to catch-up or grow appropriately.

Across the globe, the implementation of quality improvement science and collaborative learning has positively affected the care and outcomes for children born with CHD. These efforts have advanced the collective expertise and performance of inter-professional healthcare teams. In this review, we highlight selected quality improvement initiatives and strategies impacting the field of cardiovascular care and describe implications for future practice and research. The continued leveraging of technology, commitment to data transparency, focus on team-based practice, and recognition of cultural norms and preferences ensure the success of sustainable models of global collaboration.
Paradigm Shifts in the Neuropsychology of Epilepsy
Authors: Hermann Bruce , Loring David W. , Wilson Sarah
Published: December 2017

This article reviews the major paradigm shifts that have occurred in the area of the application of clinical and experimental neuropsychology to epilepsy and epilepsy surgery since the founding of the International Neuropsychological Society. The five paradigm shifts discussed include: 1) The neurobiology of cognitive disorders in epilepsy – expanding the landscape of syndrome-specific neuropsychological impairment; 2) pathways to comorbidities: bidirectional relationships and their clinical implications; 3) discovering quality of life: The concept, its quantification and applicability; 4) outcomes of epilepsy surgery: challenging conventional wisdom; and 5) Iatrogenic effects of treatment: cognitive and behavioral effects of antiepilepsy drugs. For each area we characterize the status of knowledge, the key developments that have occurred, and how they have altered our understanding of the epilepsies and their management. We conclude with a brief overview of where we believe the field will be headed in the next decade which includes changes in assessment paradigms, moving from characterization of comorbidities to interventions; increasing development of new measures, terminology and classification; increasing interest in neurodegenerative proteins; transitioning from clinical seizure features to modifiable risk factors; and neurobehavioral phenotypes. Overall, enormous progress has been made over the lifespan of the INS with promise of ongoing improvements in understanding of the cognitive and behavioral complications of the epilepsies and their treatment.

The Neuropsychology of Traumatic Brain Injury: Looking Back, Peering Ahead
Authors: Yeates Keith Owen , Levin Harvey S. , Ponsford Jennie
Published: December 2017

The past 50 years have been a period of exciting progress in neuropsychological research on traumatic brain injury (TBI). Neuropsychologists and neuropsychological testing have played a critical role in these advances. This study looks back at three major scientific advances in research on TBI that have been critical in pushing the field forward over the past several decades: The advent of modern neuroimaging; the recognition of the importance of non-injury factors in determining recovery from TBI; and the growth of cognitive rehabilitation. Thanks to these advances, we now have a better understanding of the pathophysiology of TBI and how recovery from the injury is also shaped by pre-injury, comorbid, and contextual factors, and we also have increasing evidence that active interventions, including cognitive rehabilitation, can help to promote better outcomes. The study also peers ahead to discern two important directions that seem destined to influence research on TBI over the next 50 years: the development of large, multi-site observational studies and randomized controlled trials, bolstered by international research consortia and the adoption of common data elements; and attempts to translate research into health care and health policy by the application of rigorous methods drawn from implementation science. Future research shaped by these trends should provide critical evidence regarding the outcomes of TBI and its treatment, and should help to disseminate and implement the knowledge gained from research to the betterment of the quality of life of persons with TBI.

Facilitating Autism Research
Authors: Fein Deborah , Helt Molly
Published: December 2017

Early autism research focused on behavior and cognition. In recent decades, the pace of research has accelerated, and advances in imaging and genetics have allowed the accumulation of biological data. Nevertheless, a coherent picture of the syndrome at either phenotypic or biological level has not emerged. We see two fundamental obstacles to progress in basic understanding of autism. First, the two defining features (impairment in social interactions and communication, and restricted, repetitive behaviors and interests) are historically seen as integrally related. Others hold that these two major traits are fractionable and must be studied independently, casting doubt on autism as a coherent syndrome. Second, despite much recent research on brain structure and function, environmental factors, and genetics/genomics, findings on the biological level have not generally aligned well with those on the phenotypic level. In the first two sections, we explore these challenges, and in the third section, we review approaches that may facilitate progress, such as (1) including in studies all individuals defined by social impairment without regard to repetitive behaviors, (2) forming narrowly defined subtypes by thorough characterization on specific features, both diagnostic and non-diagnostic, (3) focusing on characteristics that may be relatively robust to environmental influence, (4) studying children as early as possible, minimizing environmental influence, and including longitudinal course as an important part of the phenotype, (5) subtyping by environmental risk factors, (6) distinguishing between what participants can do and what they typically do, and (7) aggregating large data sets across sites.
