Lower Respiratory Symptoms Associated With Environmental and Reconstruction Exposures After Hurricane Sandy
Authors: Gargano Lisa M. , Locke Sean , Jordan Hannah T. , Brackbill Robert M.
Published: January 2018

Objective

In a population with prior exposure to the World Trade Center (WTC) disaster, this study sought to determine the relationship between Hurricane Sandy-related inhalation exposures and post-Sandy lower respiratory symptoms (LRS).

Methods

Participants included 3835 WTC Health Registry enrollees who completed Wave 3 (2011-2012) and Hurricane Sandy (2013) surveys. The Sandy-related inhalational exposures examined were: (1) reconstruction exposure; (2) mold or damp environment exposure; and (3) other respiratory irritants exposure. LRS were defined as wheezing, persistent cough, or shortness of breath reported on ≥1 of the 30 days preceding survey completion. Associations between LRS and Sandy exposures, controlling for socio-demographic factors, post-traumatic stress disorder, and previously reported LRS and asthma were examined using multiple logistic regression.

Results

Over one-third of participants (34.4%) reported post-Sandy LRS. Each of the individual exposures was also independently associated with post-Sandy LRS, each having approximately twice the odds of having post-Sandy LRS. We found a dose-response relationship between the number of types of Sandy-related exposures reported and post-Sandy LRS.

Conclusions

This study provides evidence that post-hurricane clean-up and reconstruction exposures can increase the risk for LRS. Public health interventions should emphasize the importance of safe remediation practices and recommend use of personal protective equipment.

Ergodic optimization in dynamical systems
Authors: JENKINSON OLIVER
Published: January 2018

Ergodic optimization is the study of problems relating to maximizing orbits and invariant measures, and maximum ergodic averages. An orbit of a dynamical system is called$f$-maximizing if the time average of the real-valued function$f$along the orbit is larger than along all other orbits, and an invariant probability measure is called$f$-maximizing if it gives$f$a larger space average than any other invariant probability measure. In this paper, we consider the main strands of ergodic optimization, beginning with an influential model problem, and the interpretation of ergodic optimization as the zero temperature limit of thermodynamic formalism. We describe typical properties of maximizing measures for various spaces of functions, the key tool of adding a coboundary so as to reveal properties of these measures, as well as certain classes of functions where the maximizing measure is known to be Sturmian.
Patients prefer a continuity model of inpatient psychiatric consultant care: a patient survey in the Louth Mental Health Service
Authors: Khan S. , Kashif M. , Wilson L. , McCauley M. , Roche E.
Published: January 2018

Objectives

The objective of the paper was to survey patients’ preference in relation to a continuity, or split, model of inpatient consultant care in the Louth Mental Health Service.

Methods

A written survey was administered to all patients attending the Louth Mental Health Service over a 2-week period. Participants were asked for their preferred model of care and clinical information was obtained from their clinical notes.

Results

In total, 149 patients completed the survey questionnaire and 103 respondents (69%) indicated a preference for a continuity model of inpatient consultant psychiatric care. There was a trend for those who reported a past experience of inpatient hospitalisation to indicate a preference for the continuity model (76%v. 61%, respectively,χ23.67,p=0.056).

Conclusions

Patients indicate a preference for a continuity model of inpatient psychiatric care and this is important to consider in service planning. More research is needed to evaluate if any model of consultant care is associated with better patient outcomes.
Was Mattarella worth the trouble? Explaining the failure of the 2016 Italian constitutional referendum
Authors: Negri Fedra , Rebessi Elisa
Published: January 2018

The election of President Mattarella is a turning point in Matteo Renzi’s attempt to reform the constitution. This choice determined the loss of Forza Italia’s support to the constitutional reform, thus leaving the Renzi cabinet and the Democratic Party alone on the Yes-side. Our goal is to assess the degree of Renzi’s misjudgment by comparing two theoretical perspectives on voting behavior in direct-democratic settings through a nested design. Our results highlight that vote choices can be explained by both the systematic and the heuristic modes of information processing. Respondents’ agreement with the content of the reform (systematic mode) and a positive evaluation of the Renzi cabinet (heuristic mode) are key predictors of Yes vote. Instead, the negative assessment of the economic situation is a crucial driver of No vote. Lastly, we build a bridge between these two perspectives by showing that partisan attachments conditioned the effect of respondents’ content evaluation on voting behavior.
Learning from the other side: how social networks influence turnout in a referendum campaign
Authors: Morisi Davide , Plescia Carolina
Published: January 2018

Interpersonal discussion is considered to be one of the most influential sources of opinion formation and behaviour. Yet, an unresolved puzzle remains within the literature: while some studies show that discussion with not like-minded citizens depresses political participation, other studies, on the contrary, indicate that the same type of interpersonal discussion can foster political engagement. In this study, we address this unresolved democratic dilemma for the first time in a context of direct democracy, by focussing on the campaign leading to the 2016 Italian constitutional referendum. Specifically, we pay particular attention to the interaction between network diversity, ambivalence, and political knowledge. The findings show that frequent interactions with not like-minded citizens increase turnout. The results based on regression models and structural equation modelling indicate that this positive effect is channelled mainly through political learning, since network diversity increases factual knowledge about the constitutional reform, which in turn is associated with an increase in turnout. We do not find a significant effect of network diversity on ambivalence, as predicted by previous studies. These findings have important implications for deliberative theories and campaign strategies.
IMMIGRANTS AS VOTERS IN ELECTORAL AUTOCRACIES: THE CASE OF MAINLAND CHINESE IMMIGRANTS IN HONG KONG
Authors: Wong Stan Hok-Wui , Ma Ngok , Lam Wai-man
Published: January 2018

Migration to electoral autocracies has become increasingly common. Extant studies, however, accord little attention to the immigrants' influences on the domestic politics of these regimes. We argue that immigrants have attributes (status quo bias and lack of prior exposure to local politics) that make them an attractive co-optation target of the authoritarian regime. We provide a case study of mainland Chinese immigrants in Hong Kong to illustrate our argument. Since the sovereignty transfer, the Hong Kong government has devised various schemes to attract these immigrants, while pro-establishment political parties and groups have actively sought to co-opt them. Using two distinct public opinion surveys, we also find that immigrants are more likely to approve of the political and economic status quo, and less likely to vote for pro-democracy opposition parties than the natives. In addition, we find no evidence that exposure to political information can change the immigrants' vote choice.
Motivational Benefits of Social Support and Behavioural Interventions for Smoking Cessation
Authors: Soulakova Julia N. , Tang Chiung-Ya , Leonardo Selena A. , Taliaferro Lindsay A.
Published: January 2018

This study examined the role of social support and behavioural interventions used during the last unsuccessful quit attempt for smokers’ intentions to quit smoking within the next six months, and identified smokers’ attributes associated with the use of social support and behavioural interventions. The analytic sample included 7,195 adult daily smokers who responded to the 2010–2011 Tobacco Use Supplement to the Current Population Survey, conducted in the United States, and indicated having a serious quit attempt in the past 12 months. Smokers who relied on social support from friends and family had higher odds of intending to quit than those who did not (OR = 1.39, 95% CI = 1.22:1.58), and smokers who used interventions had higher odds of intending to quit than those who did not (OR = 1.36, 95% CI = 1.07:1.74). These associations were similar for both sexes, all age groups, and nicotine dependence levels. Both, relying on social support and the use of behavioural interventions were more common among smokers who were female, higher educated, residing in the Western US region, and those who used pharmacological aids for smoking cessation. Social support and behavioural interventions are associated with higher intentions to quit among attempters who relapsed and thus, may aid future smoking cessation.
Does adherence to the World Cancer Research Fund/American Institute of Cancer Research cancer prevention guidelines reduce risk of colorectal cancer in the UK Women’s Cohort Study?
Authors: Jones Petra , Cade Janet E. , Evans Charlotte E. L. , Hancock Neil , Greenwood Darren C.
Published: January 2018

Evidence on adherence to diet-related cancer prevention guidelines and associations with colorectal cancer (CRC) risk is limited and conflicting. The aim of this cohort analysis is to evaluate associations between adherence to the World Cancer Research Fund/American Institute of Cancer Research (WCRF/AICR) 2007 recommendations and incident CRC. The UK Women’s Cohort Study comprises over 35 372 women who filled in a FFQ at baseline in 1995. They were followed up for CRC incidence for a median of 17·4 years, an individual score linking adherence to eight of the WCRF/AICR recommendations was constructed. Cox proportional hazards regression provided hazard ratios (HR) and 95 % CI for the estimation of CRC risk, adjusting for confounders. Following exclusions, 444 CRC cases were identified. In the multivariate-adjusted model, women within the second and third (highest) categories of the WRCF/AICR score had HR of 0·79 (95 % CI 0·62, 1·00) and 0·73 (95 % CI 0·48, 1·10), respectively, for CRC compared with those in the lowest, reference category. The overall linear trend across the categories was not significant (P=0·17). No significant associations were observed between the WCRF/AICR score and proximal colon, distal colon and rectal cancers separately. Of the individual score components, a BMI within the normal weight range was borderline significantly protective only for rectal cancer in the fully adjusted model. In view of the likely different causes of CRC subtypes, further research is needed to identify the optimal dietary patterns associated with reducing colon and rectal cancer risk, respectively.
WHERE WAS THE CHURCH OF ENGLAND, 1646–1660?
Authors: HAIGH CHRISTOPHER
Published: January 2018

When parliament abolished episcopacy, cathedrals, and the Book of Common Prayer, what was left of the Church of England? Indeed, as contemporaries asked between 1646 and 1660, ‘Where is the Church of England?’ The episcopalian clergy could not agree. Some thought the remaining national framework of parishes and congregations was ‘the Church of England’, though now deformed, and worked within it. Others thought that only those ministers and parish congregations who remained loyal in heart to the church as it had been qualified as ‘the church’: most of them continued to serve a parish church and tried to keep the old practices going. A third category of hard-liners thought ‘the Church of England’ was now restricted to a recusant community that worshipped with the Prayer Book in secret and rejected the new national profession. The fundamental issue was the nature of a church: was it a society of believers, however organized, or a hierarchical institution following rules prescribed by God? The question caused tensions and distrust among the clergy, and the rigorists thought of the rest as time-servers and traitors. Disagreements continued to divide the clergy after the Restoration, and were reflected in attitudes towards concessions to dissenters.
From the Streets to the Government: Socialist Militants and Labour Law in Brazil

Published: January 2018

This article analyses and compares the careers of a group of socialist militants who were active in several regions of Brazil in the final decades of the nineteenth century and the early twentieth century. It underscores their similarities and differences with a view to understanding the various ways of being a socialist in that context. This includes examining their wide-ranging activities, the main ideas they upheld, and their role in the development of Brazilian labour laws in the 1930s and 1940s.1
THE ASSOCIATION BETWEEN SEXUAL BEHAVIOURS AND INITIATION OF POST-SECONDARY EDUCATION IN SOUTH AFRICA
Authors: Bengesai Annah V. , Khan Hafiz T. A. , Dube Russell
Published: January 2018

Although young people in South Africa are growing up in an era where their socioeconomic circumstances are seemingly better than those of their parents’ generation, they face greater risks in their trajectory to adulthood. This is mainly because the environment in which they are making sexual decisions is also rapidly evolving. Currently, South Africa has the highest prevalence of HIV and AIDS in the world among young people aged 15–24. This study examined the effect of sexual behaviours initiated in adolescence on enrolment in post-secondary education. The analysis was conducted using data from the longitudinal Cape Area Panel Study (CAPS, Waves 1–5) conducted in 2002–2009, which focused on young people’s sexual behaviours in Cape Town, South Africa. The sample was restricted to 3213 individuals who reported sexual debut during adolescence. Using logistic regression models fitted separately for males and females, the results revealed that several factors acted as either hindrances or protective factors to enrolment in post-secondary education. Early sexual debut (by age 17) was negatively associated with participation in tertiary education. Other variables that had a negative effect included not using contraception at first sex, parenthood, engaging in risky behaviours such as illegal substance use, cigarette smoking and drinking alcohol and neglect of school homework (doing less than an hour a day). Higher levels of parental education (except for paternal education in the female model), urban residence and higher aspirations and analogous behaviours (studying) acted as protective factors and were positively associated with post-secondary education initiation. The paper also points to the relationship between early sexual debut and persistent socioeconomic inequality and provides empirical evidence for re-thinking policy development and implementation around schooling and sex education.
AGE AT MENARCHE AND SEXUAL DEBUT AMONG YOUNG FILIPINO WOMEN
Authors: Tey Nai-Peng , Lai Siow-Li , Ng Sor-Tho
Published: January 2018

There has been a secular decline in age at menarche since the 19th century. Early-maturing women are more likely to have their sexual debut at a younger age, which in turn gives rise to a host of reproductive health and social problems. This study used data from five waves of National Demographic and Health Surveys conducted in the Philippines between 1993 and 2013 to examine the trends and socioeconomic differentials in age at menarche and sexual debut. The changing trend in age at menarche and sexual debut was examined across birth cohorts, and logistic regressions were used to identify the determinants of early sexual debut. In the Philippines, the mean and median ages at menarche declined from 13.2 years and 12.6 years, respectively, among young women born in 1973–1977, to 12.9 years and 12.3 years, respectively, among those born in 1993–1997. The proportion who had their sexual debut by age 20 increased from 41.2% for the 1968–1972 birth cohort to 53.4% for the 1988–1992 birth cohort. Filipino women with low education, from poor families and living in rural areas were more likely to have earlier sexual debut despite attaining menarche at a later age as compared with their higher educated counterparts, and those from wealthier families and urban areas. Logistic regression analysis showed that, besides marital status, women’s education and age at menarche were important determinants of early sexual debut. However, ethnicity, place of residence and family wealth had no significant effects on age at menarche. An increasing proportion of young women were found to be having unprotected sexual debut and at a younger age, with health and social ramifications. Hence, apart from increasing the enrolment of girls in schools and discouraging teenage marriage, there is a need for social and health agencies to implement appropriate adolescent sexual and reproductive health programmes such as counselling and educational campaigns, as well as support services, to address sexual problems among the youth.
Emotional coping among communities affected by wildlife–caused damage in north-east India: opportunities for building tolerance and improving conservation outcomes
Authors: Gogoi Mayuri
Published: January 2018

Human–wildlife conflict has been the focus of much research, and incidents of damage caused by wildlife to communities, as well as damage inflicted on wildlife by people, have been studied extensively to determine causes, conditions, impacts and mitigation strategies. However, few studies have explored the coping strategies employed by communities to deal with these stressful events. Understanding coping is important, as effective coping builds tolerance towards wildlife, whereas poor coping erodes tolerance and thus jeopardizes conservation. Interviews conducted with people who had experienced damage caused by wild elephantsElephas maximusin eight villages of Assam, in north-east India, found that the stress experienced by the communities as a result of the damage was eased by their religious beliefs associated with elephants, and their feelings of empathy towards these animals. Belief in the elephant as God and as avenger of wrong-doing further strengthened people's coping capacity. These findings have positive implications for elephant conservation, showing that people's tolerance towards marauding elephants can be based on religious beliefs rather than compensation for losses.
An ecological momentary assessment evaluation of emotion regulation abnormalities in schizophrenia
Authors: Visser Katherine Frost , Esfahlani Farnaz Zamani , Sayama Hiroki , Strauss Gregory P.
Published: January 2018

Background

Prior studies using self-report questionnaires and laboratory-based methods suggest that schizophrenia is characterized by abnormalities in emotion regulation (i.e. using strategies to increase or decrease the frequency, duration, or intensity of negative emotion). However, it is unclear whether these abnormalities reflect poor emotion regulation effort or adequate effort, but limited effectiveness. It is also unclear whether dysfunction results primarily from one of the three stages of the emotion regulation process: identification, selection, or implementation.

Method

The current study used ecological momentary assessment (EMA) to address these questions in the context of everyday activities. Participants included 28 outpatients diagnosed with schizophrenia (SZ) and 28 demographically matched healthy controls (CN) who completed 6 days of EMA reports of in-the-moment emotional experience, emotion regulation strategy use, and context.

Results

Results indicated that SZ demonstrated adequate emotion regulation effort, but poor effectiveness. Abnormalities were observed at each of the three stages of the emotion regulation process. At the identification stage, SZ initiated emotion regulation efforts at a lower threshold of negative emotion intensity. At the selection stage, SZ selected more strategies than CN and strategies attempted were less contextually appropriate. At the implementation stage, moderate to high levels of effort were ineffective at decreasing negative emotion.

Conclusions

Findings suggest that although SZ attempt to control their emotions using various strategies, often applying more effort than CN, these efforts are unsuccessful; emotion regulation abnormalities may result from difficulties at the identification, selection, and implementation stages.
Retrieval is central to the distinctive function of episodic memory
Authors: Aronowitz Sara
Published: January 2018

Episodic retrieval is heavily and asymmetrically dependent on the temporal order of the remembered events. This effect, or rather the underlying structure which it reflects, is a distinctive feature missing from the account in the target article. This structure explains significant successes and failures of episodic retrieval, and it has clear consequences for the fitness of the organism extending beyond communication.
Episodic memory must be grounded in reality in order to be useful in communication
Authors: Blank Hartmut
Published: January 2018

The primary function of episodic memory is to provide reliable information about reality that is essential for surviving and navigating in an environment. The communicative function of episodic memory “sits on top of” this basic function but does not, in itself, explain it in its totality (but may explain particular aspects such as its sensitivity to source credibility).
Why episodic memory may not be for communication
Authors: De Brigard Felipe , Gessell Bryce
Published: January 2018

Three serious challenges to Mahr & Csibra's (M&C's) proposal are presented. First, we argue that the epistemic attitude that they claim is unique to remembering also applies to some forms of imaginative simulations that aren't memories. Second, we argue that their account cannot accommodate critical neuropsychological evidence. Finally, we argue that their proposal looks unconvincing when compared to more parsimonious evolutionary accounts.
Sleep to be social: The critical role of sleep and memory for social interaction
Authors: Diekelmann Susanne , Paulus Frieder M. , Krach Sören
Published: January 2018

Humans are highly social animals who critically need to remember information from social episodes in order to successfully navigate future social interactions. We propose that such episodic memories about social encounters are processed during sleep, following the learning experience, with sleep abstracting and consolidating social gist knowledge (e.g., beliefs, first impressions, or stereotypes) about others that supports relationships and interpersonal communication.
Beyond communication: Episodic memory is key to the self in time
Authors: Szpunar Karl K. , Chan Jason C. K.
Published: January 2018

Mahr & Csibra (M&C) propose that episodic memory evolved to support epistemic authority in social communication. We argue for a more parsimonious interpretation whereby episodic memory subserves a broader preparatory function for both social and non-social behavior. We conclude by highlighting that functional accounts of episodic memory may need to consider the complex interrelations between self and subjective time.
Emotional memories and how your life may depend upon them
Authors: Eaton Tayler , Anderson Adam K.
Published: January 2018

In this commentary, we discuss how one's internal body state and the appraisals an individual utilizes at encoding alter later episodic memory irrespective of social discourse. We suggest that the purpose of episodic memory is originally the preservation of the self, which may have been co-opted to navigating the social world.
Brain disorders? Not really: Why network structures block reductionism in psychopathology research
Authors: Borsboom Denny , Cramer Angélique O. J. , Kalis Annemarie
Published: January 2018

In the past decades, reductionism has dominated both research directions and funding policies in clinical psychology and psychiatry. The intense search for the biological basis of mental disorders, however, has not resulted in conclusive reductionist explanations of psychopathology. Recently, network models have been proposed as an alternative framework for the analysis of mental disorders, in which mental disorders arise from the causal interplay between symptoms. In this target article, we show that this conceptualization can help explain why reductionist approaches in psychiatry and clinical psychology are on the wrong track. First, symptom networks preclude the identification of a common cause of symptomatology with a neurobiological condition; in symptom networks, there is no such common cause. Second, symptom network relations depend on the content of mental states and, as such, feature intentionality. Third, the strength of network relations is highly likely to depend partially on cultural and historical contexts as well as external mechanisms in the environment. Taken together, these properties suggest that, if mental disorders are indeed networks of causally related symptoms, reductionist accounts cannot achieve the level of success associated with reductionist disease models in modern medicine. As an alternative strategy, we propose to interpret network structures in terms of D. C. Dennett's (1987) notion ofreal patterns, and suggest that, instead of being reducible to a biological basis, mental disorders feature biological and psychological factors that are deeply intertwined in feedback loops. This suggests that neither psychological nor biological levels can claim causal or explanatory priority, and that a holistic research strategy is necessary for progress in the study of mental disorders.
DEVELOPMENT ECONOMICS AND THE RUSSIAN REVOLUTION: THE SOVIET INDUSTRIALISATION DEBATE
Authors: Azqueta Diego
Published: January 2018

After the triumph of the October Revolution in Russia the issue of how to develop a backward economy towards a socialist society took pre-eminence. The relationship between agriculture and industry was one of the key issues. In this respect, the Left Opposition argued in favour of a Big Push for industrialisation financed through the exploitation of the peasantry, while the Right Deviation defended adjusting industrial growth to the development of the agricultural surplus. The First 5-Year Plan meant the complete victory of one of these positions. Unfortunately, all discussions were banned subsequently, the leading figures of these two factions were expelled from the Party and many of them executed. Yet, this problem was of the utmost importance for underdeveloped countries, as Development Economics was to discover 25 years later. This new branch of Economics would have benefitted greatly from the lessons of the Soviet experience regarding industrialisation, as well as from the theoretical discussions surrounding it.
A coaxial-output rolled strip pulse forming line based on multi-layer films

Published: January 2018

A coaxial-output rolled strip pulse-forming line (RSPFL) with a dry structure is researched for the purpose of miniaturization and all-solid state of pulse-forming lines (PFL). The coaxial-output RSPFL consists of a coaxial-output electrode (COE) and a rolled strip line (RSL). The COE is characterized by quasi-coaxial structure, making the output pulse propagate along the axial direction with a small output inductance. The RSL is rolled on the COE, whose transmission characteristics are analyzed theoretically. It shows that the RSL can be regarded as a planar strip line when the rolling radius of the strip line is larger than 60 times of the thickness of the insulation dielectric layer of RSL. CST modeling was carried out to simulate the discharging characteristic of the coaxial-output RSPFL. It shows that the coaxial-output RSPFL can deliver a discharging pulse with a rise time <6 ns when the impedance of the RSL matches that of the COE, which confirms the theoretical analysis. A prototype of the coaxial-output RSPFL was developed. A 49-kV discharging pulse on a matched load was achieved when it was charged to 100 kV. The discharging waveform has a pulse width of 32 ns, with a rise time of 6 ns, which is consistent with the simulation waveform. An energy-storage density of 1.9 J/L was realized in the coaxial-output RSPFL. By the method of multi-stage connection in series, a much higher output voltage is convenient to be obtained.
Robust adaptive command filtered control of a robotic manipulator with uncertain dynamic and joint space constraints
Authors: Ahanda Joseph Jean-Baptiste Mvogo , Mbede Jean Bosco , Melingui Achille , Zobo Bernard Essimbi
Published: January 2018

The problem of robust adaptive control of a robotic manipulator subjected to uncertain dynamics and joint space constraints is addressed in this paper. Command filters are used to overcome the time derivatives of virtual control, thus reducing the need for desired trajectory differentiations. A barrier Lyapunov function is used to deal with the joint space constraints. A robust adaptive support vector regression architecture is used to reduce filtering errors, approximation errors and handle dynamic uncertainties. The stability analysis of the closed-loop system using the Lyapunov theory permits to highlight adaptation laws and to prove that all signals of the closed-loop system are bounded. Simulations show the effectiveness of the proposed control strategy.
Optimal planning in robotized cladding processes on generic surfaces
Authors: Magnoni Paolo , Pedrocchi Nicola , Thieme Sebastian , Legnani Giovanni , Molinari Tosatti Lorenzo
Published: January 2018

Cladding through laser metal deposition is a promising application of additive manufacturing. On the one hand, industrial robots are increasingly used in cladding because they provide wide wrist reorientation, which enables manufacturing of complex geometries. On the other hand, limitations in robot dynamics may prevent cladding of sharp edges and large objects. To overcome these issues, this paper aims at exploiting the residual degrees of freedom granted by the cladding process for the optimization of the deposition orientation. The proposed method optimizes the robot head orientation along a predefined path while coping with kino-dynamic constraints as well as process constraints. Experimental tests and results are reported and used to validate the approach.
Synthesis of cerium oxide (CeO2) by co-precipitation for application as a reference material for X-ray powder diffraction peak widths
Authors: de Lima Batista Anderson Márcio , Miranda Marcus Aurélio Ribeiro , Martins Fátima Itana Chaves Custódio , Morilla Santos Cássio , Sasaki José Marcos
Published: January 2018

Several methods can be used to obtain, from powder diffraction patterns, crystallite size and lattice strain of polycrystalline samples. Some examples are the Scherrer equation, Williamson–Hall plots, Warren/Averbach Fourier decomposition, Whole Powder Pattern Modeling, and Debye function analysis. To apply some of these methods, it is necessary to remove the contribution of the instrument to the widths of the diffraction peaks. Nowadays, one of the main samples used for this purpose is the LaB6 SRM660b commercialized by the National Institute of Standard Technology; the width of the diffraction peak of this sample is caused only by the instrumental apparatus. However, this sample can be expensive for researchers in developing countries. In this work, the authors present a simple route to obtain micron-sized polycrystalline CeO2 that have a full width at half maximum comparable with the SRM660b and therefore it can be used to remove instrumental broadening.
Disease burden of psittacosis in the Netherlands
Authors: de Gier B. , Hogerwerf L. , Dijkstra F. , van der Hoek W.
Published: January 2018

Psittacosis (infection with Chlamydia psittaci) can have diverse presentations in humans, ranging from asymptomatic infection to severe systemic disease. Awareness of psittacosis and its presentations are low among clinicians and the general public. Therefore, underdiagnosis and thereby underestimation of the incidence and public health importance of psittacosis is very likely. We used the methodology developed for the Burden of communicable diseases in Europe toolkit of the European Centre for Disease Prevention and Control, to construct a model to estimate disease burden in disability-adjusted life years (DALYs) attributable to psittacosis. Using this model, we estimated the disease burden caused by psittacosis in the Netherlands to have been 222 DALY per year (95% CI 172–280) over the period 2012–2014. This is comparable with the amount of DALYs estimated to be due to rubella or shigellosis in the same period in the Netherlands. Our results highlight the public health importance of psittacosis and identify evidence gaps pertaining to the clinical presentations and prognosis of this disease.
Balanced viscosity solutions to a rate-independent system for damage
Authors: KNEES DOROTHEE , ROSSI RICCARDA , ZANINI CHIARA
Published: January 2018

This article is the third one in a series of papers by the authors on vanishing-viscosity solutions to rate-independent damage systems. While in the first two papers (Knees, D. et al. 2013 Math. Models Methods Appl. Sci.23(4), 565–616; Knees, D. et al. 2015 Nonlinear Anal. Real World Appl.24, 126–162) the assumptions on the spatial domain Ω were kept as general as possible (i.e., non-smooth domain with mixed boundary conditions), we assume here that ∂Ω is smooth and that the type of boundary conditions does not change. This smoother setting allows us to derive enhanced regularity spatial properties both for the displacement and damage fields. Thus, we are in a position to work with a stronger solution notion at the level of the viscous approximating system. The vanishing-viscosity analysis then leads us to obtain the existence of a stronger solution concept for the rate-independent limit system. Furthermore, in comparison to [18, 19], in our vanishing-viscosity analysis we do not switch to an artificial arc-length parameterization of the trajectories but we stay with the true physical time. The resulting concept of Balanced Viscosity solution to the rate-independent damage system thus encodes a more explicit characterization of the system behaviour at time discontinuities of the solution.
Social Sciences, Humanities and Liberal Arts: China and the West
Authors: Kang Liu
Published: January 2018

For the most part, modern China’s institutions and modes of knowledge have been shaped and predominantly influenced by the West. Since the modern Chinese knowledge system is an integral and inseparable part of that dominant western system, an immanent critique will view Chinese problems not as extraneous, but as intrinsic to modernity, to the world-system or globalization. This article traces the genealogy of modern European modes of knowledge under the rubrics of ‘liberal arts’, as the origin and basis for modern China’s institutions and modes of knowledge, and then examines China’s ‘liberal arts’ as institution and modes of knowledge from the early years of the twentieth century to the present. The paper’s objective is to question the relationship between (Eurocentric) universalism and Chinese exceptionalism within the dominant modern Western institutions and modes of knowledge today.

Published: January 2018

Objective

To assess under real community settings the effectiveness of the WHO strategy of home fortification of foods (HFF) with multiple-micronutrient powders on Hb change, anaemia and weight in children.

Design

A pragmatic cluster-randomized controlled trial.

Setting

Forty villages in the Nioro Circle in Mali and 722 children aged 6–23 months were randomized to the intervention or control group. The intervention consisted of a daily dose of multiple-micronutrient powder for 3 months; in the control group, no supplement was given. In both groups, mothers received group education on child complementary feeding. Changes in weight, Hb concentration and anaemia were assessed as primary outcomes at baseline and 3 months. The HFF effect was determined using regression analyses and quantile regression with standard errors taking account of the cluster design.

Subjects

Children aged 6–23 months.

Results

Overall prevalence of anaemia in the sample was high: 90 %. HFF provided a modest but statistically significant Hb changev. no intervention (0·50v. 0·09 g/dl,P=0·023). Prevalence of anaemia changed little: 91·3–85·8 % (P=0·04) in the intervention groupv. 88·1–87·5 % % (P=0·86) in the control group. Proportion of severe anaemia was reduced by 84 % (from 9·8 to 1·6 %) in the intervention group, but increased in the control group (from 8·5 to 10·8 %). No effect was observed on weight.

Conclusions

The WHO HFF strategy to fight anaemia showed a modest change on Hb concentration and significantly reduced the rate of severe anaemia.

Objective

Encouraging people to eat more seafood can offer a direct, cost-effective way of improving overall health outcomes. However, dietary recommendations to increase seafood consumption have been criticised following concern over the capacity of the seafood industry to meet increased demand, while maintaining sustainable fish stocks. The current research sought to investigate Australian accredited practising dietitians’ (APD) and public health nutritionists’ (PHN) views on seafood sustainability and their dietary recommendations, to identify ways to better align nutrition and sustainability goals.

Design

A self-administered online questionnaire exploring seafood consumption advice, perceptions of seafood sustainability and information sources of APD and PHN. Qualitative and quantitative data were collected via open and closed questions. Quantitative data were analysed with χ2 tests and reported using descriptive statistics. Content analysis was used for qualitative data.

Setting

Australia.

Subjects

APD and PHN were targeted to participate; the sample includes respondents from urban and regional areas throughout Australia.

Results

Results indicate confusion around the concept of seafood sustainability and where to obtain information, which may limit health professionals’ ability to recommend the best types of seafood to maximise health and sustainability outcomes. Respondents demonstrated limited understanding of seafood sustainability, with 7·5 % (n 6/80) satisfied with their level of understanding.

Conclusions

Nutrition and sustainability goals can be better aligned by increasing awareness on seafood that is healthy and sustainable. For health professionals to confidently make recommendations, or identify trade-offs, more evidence-based information needs to be made accessible through forums such as dietetic organisations, industry groups and nutrition programmes.

Introduction

Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy. The purpose of this research is comparison between 6 MV Primus LINAC simulation output with commissioning data using EGSnrc and build a Monte Carlo geometry of 6 MV Primus LINAC as realistically as possible. The BEAMnrc and DOSXYZnrc (EGSnrc package) Monte Carlo model of the LINAC head was used as a benchmark.

Methods

In the first part, the BEAMnrc was used for the designing of the LINAC treatment head. In the second part, dose calculation and for the design of 3D dose file were produced by DOSXYZnrc. The simulated PDD and beam profile obtained were compared with that calculated using commissioning data. Good agreement was found between calculated PDD (1·1%) and beam profile using Monte Carlo simulation and commissioning data. After validation, TPR20,10, TMR and Spvalues were calculated in five different field.

Results

Good agreement was found between calculated values by using Monte Carlo simulation and commissioning data. Average differences for five field sizes in this approach is about 0·83% for Sp. for TPR20,10differences for field sizes 10×10 cm2is 0·29% and for TMR in five field sizes, the average value is ~1·6%.

Conclusion

In conclusion, the BEAMnrc and DOSXYZnrc codes package have very good accuracy in calculating dose distribution for 6 MV photon beam and it can be considered as a promising method for patient dose calculations and also the Monte Carlo model of primus linear accelerator built in this study can be used as method to calculate the dose distribution for cancer patients.
A brief assessment unravels unmet needs of older people in primary care: a mixed-methods evaluation of the SPICE tool in Portugal

Published: January 2018

Assessments of need may contribute to identifying health problems associated with functional deterioration in older people. A shorter version of the Camberwell Assessment of Need for the Elderly was developed for routine use in primary care, focusing on five domains: Senses, Physical ability, Incontinence, Cognition, and Emotional distress (SPICE). We aimed to explore its usefulness and feasibility in primary care.

We selected a consecutive sample of 51 community-dwelling older adults. The SPICE interview was completed by GPs and patients, with perceptions about its use in primary care being explored.

Needs were identified in 38 patients. Unmet needs corresponded to 7% of needs overall. ‘Emotional distress’ was the most frequent unmet need. SPICE helped to identify undisclosed needs, was well accepted and its importance in clinical evaluation recognised by GPs and patients, despite concerns about time constraints. Facilitating strategies are needed to improve the feasibility of these assessments in primary care.
Input Cost Adjustments and WTO Anti-Dumping Law: A Closer Look at the EU Practice
Authors: SHADIKHODJAEV SHERZOD
Published: January 2018

In anti-dumping procedures, the EU authorities have adjusted State-distorted input costs in the constructed normal value to market benchmarks. This methodology increases the amount of anti-dumping duties and hence import barriers to foreign goods produced with low-priced raw materials. Such cost adjustments are based on certain EU anti-dumping provisions that implement corresponding World Trade Organization (WTO) rules under which the cost of input must be derived, as a principle, from the records of target companies in the exporting country if those records, inter alia, reasonably reflect production costs of the product under investigation. But in the case of input costs distorted by the government, the EU authorities have typically deviated from this principle relying on alternative sources on the grounds of unreasonable costs. While the EU jurisprudence has so far been generally lenient towards this methodology as applied to significant distortions in the raw material (upstream) market, the recent WTO appellate ruling inEU–Biodieselis rather negative on its use in the presence of the valid domestic records. This article examines the EU anti-dumping practice as reviewed in both EU and WTO judicial proceedings and discusses some legislative reforming options under both regimes. It concludes that the WTO anti-dumping rules should be amended to allow market-oriented cost adjustments in the normal value, on the one hand, and ensure parallel export price adjustments, on the other.
Intragenerational redistribution in a funded pension system
Authors: FRASSI BENEDETTA , GNECCO GIORGIO , PAMMOLLI FABIO , WEN XUE
Published: January 2018

In a general equilibrium framework, this paper studies the properties, in terms of labour market distortions and capital accumulation, of three social security systems: a pay-as-you-go notional defined contribution (PAYG NDC), a fully funded (FF), and a novel modified FF (MFF) system, which includes an intragenerational redistributive component to guarantee minimum living standards to future low-income retirees. We show that while PAYG NDC depresses labour supply and physical capital accumulation, FF is neutral on both dimensions. Conversely, MFF slightly increases physical capital accumulation, without significantly reducing labour supply incentives. Moreover, it reduces the burden of future intergenerational redistribution, and increases social welfare.
“You either need help…you feel you don't need help…or you don't feel worthy of asking for it:” Receptivity to bereavement support
Authors: Blackburn Pippa , Bulsara Caroline
Published: January 2018

Objective

Although the needs of the bereaved have been identified widely in the literature, how these needs translate into meaningful, appropriate, and client-centered programs needs further exploration. The application of receptivity to support is a critical factor in participation by the bereaved in palliative care bereavement programs. Receptivity is a complex multifactorial phenomenon influenced by internal and external factors that ultimately influences engagement in psychosocial support in bereavement. This study explored factors that influence receptivity to bereavement support from palliative care services in rural, regional, and remote Western Australia.

Method

The study comprised a qualitative descriptive research design using semistructured interviews with 24 bereaved individuals, nine palliative care health professionals, and four Aboriginal Health Professionals. Participants were recruited via palliative care services in country Western Australia. Interviews were transcribed verbatim and thematically analyzed.

Result

Findings revealed that a range of individual, social, and geographical factors influence receptivity to bereavement support and can impact on utilization of bereavement support services.

Significance of results

Receptivity provides a frame of reference to enhance understanding of factors influencing engagement in psychosocial support in bereavement. Receptivity promotes a shift of service provider perspectives of effective supportive care to consumer-centric reasons for engagement.
