Whose equality? Measuring group representation
Authors: Celis Karen , Mügge Liza M
Published: January 2017

Presence, of bodies and ideas, is often taken as the primary indicator of political equality and, hence, democratic health. Intersectionality and constructivism question the validity of measuring presence. Turning theory into practice, we propose a comparative reflexive design guided by two research questions: (1) Who are the groups? and (2) What are their problems? This reveals both prototypical and non-prototypical groups and interests, from the perspectives of politicians (from above) and citizens (from below). We suggest concrete qualitative and quantitative methodological strategies to study these questions empirically.
Parent Educational Involvement in Middle School: Longitudinal Influences on Student Outcomes
Authors: Garbacz S. Andrew , Zerr Argero A. , Dishion Thomas J. , Seeley John R. , Stormshak Elizabeth
Published: January 2017

The present study examined influences of sixth-grade student-reported parent educational involvement on early adolescent peer group affiliations at seventh and eighth grade. In addition, student gender and ethnicity were explored as possible moderators. Drawn from a large effectiveness trial, participants in this study were 5,802 early adolescents across 20 middle schools in the northwest region of the United States. Findings suggested that specifically parent’s educational involvement in sixth grade predicted increases in positive peer affiliation, when controlling for a general score of parent monitoring practices. The relation between parent educational involvement and peer affiliation varied by student ethnicity but not by gender. Findings suggest the social benefits of parent’s engagement with the school context on early adolescent development.
Clinical Outcome of Arthroscopic Bankart Repair Combined With Simultaneous Capsular Repair
Authors: Nakagawa Shigeto , Iuchi Ryo , Mae Tatsuo , Mizuno Naoko , Take Yasuhiro
Published: January 2017

Background:

A capsular tear and humeral avulsion of the glenohumeral ligament lesion are not uncommon findings in association with a Bankart lesion. However, there have been few reports regarding the prevalence of such capsular lesions and the postoperative recurrence after capsular repair.

Purpose/Hypothesis:

This study investigated the prevalence of capsular lesions and clarified their influence on the postoperative recurrence of instability. In addition, factors were identified that were associated with the occurrence of capsular lesions and the postoperative recurrence of instability. We hypothesized that clinical outcomes would be improved by combining arthroscopic Bankart repair with simultaneous capsular repair.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Capsular lesions were retrospectively examined through operative records, still pictures, and videos in 172 shoulders with traumatic anterior instability. First, the prevalence of capsular lesions and their severity were investigated. Then, postoperative recurrence was determined in shoulders observed for a minimum of 2 years. Finally, factors were assessed that were associated with the occurrence of capsular lesions and the postoperative recurrence of instability.

Results:

A capsular lesion was recognized in 37 shoulders (21.5%), being severe and mild in 20 and 17, respectively. All were repaired simultaneously with the arthroscopic Bankart procedure. After follow-up for at least 2 years, recurrence of instability was detected in 10 of 34 shoulders (29.4%), including 6 (31.6%) with severe capsular lesions and 4 (26.7%) with mild lesions. The recurrence rate was significantly higher in shoulders with a capsular lesion than in shoulders without a capsular lesion (18 of 120, 15%; P = .013), but there was no significant difference between severe and mild lesions. Regardless of the sport played, capsular lesions were significantly more frequent in patients ≥30 years old, patients with complete dislocation, and patients with a coexisting Hill-Sachs lesion. Postoperative recurrence of instability was significantly more frequent in patients <30 years and competitive athletes.

Conclusion:

In shoulders undergoing arthroscopic Bankart repair, capsular lesions were often present and were associated with higher postoperative recurrence of instability. While these lesions were more frequent in older patients, postoperative recurrence of instability was more likely in young competitive athletes.
Outcome of Hip Impingement Surgery: Does Generalized Joint Hypermobility Matter?
Authors: Naal Florian D. , Müller Aileen , Varghese Viju D. , Wellauer Vanessa , Impellizzeri Franco M. , Leunig Michael
Published: January 2017

Background:

Generalized joint hypermobility (JH) might negatively influence the results of surgical femoroacetabular impingement (FAI) treatment, as JH has been linked to musculoskeletal pain and injury incidence in athletes. JH may also be associated with worse outcomes of FAI surgery in thin females.

Purpose:

To (1) determine the results of FAI surgery at a minimum 2-year follow-up by means of patient-reported outcome measures (PROMs) and failure rates, (2) assess the prevalence of JH in FAI patients and its effect on outcomes, and (3) identify other risk factors associated with treatment failure.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We included 232 consecutive patients (118 females; mean age, 36 years) with 244 hips surgically treated for symptomatic FAI between 2010 and 2012. All patients completed different PROMs preoperatively and at a mean follow-up of 3.7 years. Satisfaction questions were used to define subjective failure (answering any of the 2 subjective questions with dissatisfied/ very dissatisfied and/or didn’t help/ made things worse). Conversion to total hip replacement (THR) was defined as objective failure. JH was assessed using the Beighton score.

Results:

All PROM values significantly ( P < .001) improved from preoperative measurement to follow-up (Oxford Hip Score: 33.8 to 42.4; University of California at Los Angeles Activity Scale: 6.3 to 7.3; EuroQol−5 Dimension Index: 0.58 to 0.80). Overall, 34% of patients scored ≥4 on the Beighton score, and 18% scored ≥6, indicating generalized JH. Eleven hips (4.7%) objectively failed and were converted to THR. Twenty-four patients (10.3%) were considered as subjective failures. No predictive risk factors were identified for subjective failure. Tönnis grade significantly ( P < .001) predicted objective failure (odds ratio, 13; 95% CI, 4-45). There was a weak inverse association ( r = −0.16 to −0.30) between Beighton scores and preoperative PROM values. There were no significant associations between Beighton scores and postoperative PROM values or subjective failure rates, but patients who objectively failed had lower Beighton scores than did nonfailures (1.6 vs 2.6; P = .049).

Conclusion:

FAI surgery yielded favorable outcomes at short- to midterm follow-up. JH as assessed by the Beighton score was not consistently associated with subjective and objective results. Joint degeneration was the most important risk factor for conversion to THR. Although statistical significance was not reached, female patients with no joint degeneration, only mild FAI deformity, and higher Oxford scores at the time of surgery seemed to be at increased risk for subjective dissatisfaction.
Infantile Serine Biosynthesis Defect Due to Phosphoglycerate Dehydrogenase Deficiency: Variability in Phenotype and Treatment Response, Novel Mutations, and Diagnostic Challenges
Authors: Benke Paul J. , Hidalgo Ryan J. , Braffman Bruce H. , Jans Judith , Gassen Koen L.I. van , Sunbul Rawda , El-Hattab Ayman W.
Published: January 2017

Serine biosynthesis defects can present in a broad phenotypic spectrum ranging from Neu-Laxova syndrome, a lethal disease with multiple congenital anomalies at the severe end, to an infantile disease with severe psychomotor retardation and seizures as an intermediate phenotype, to a childhood disease with intellectual disability at the mild end. In this report we present 6 individuals from 3 families with infantile phosphoglycerate dehydrogenase (PGDH) deficiency who presented with psychomotor delay, growth failure, microcephaly, and spasticity. The phenotype was variable with absence of seizures in 2 sisters in family 1 and 1 infant in family 2 and seizures with pronounced happy affect in 3 sisters in family 3. The initiation of serine treatment had pronounced effect on seizures and spasticity in the sisters in family 3, but minimal developmental effects on the children in families 1 and 2. With such phenotypic variability, the diagnosis of PGDH deficiency can be challenging.
An Exploratory Thematic Analysis of the Breastfeeding Experience of Students at a Canadian University
Authors: West Jenna Mackenzie , Power Jessica , Hayward Kathryn , Joy Phillip
Published: January 2017

Background:

The demographic of today’s university student includes breastfeeding mothers. Few studies have examined the breastfeeding experience that women face upon their return to school.

Research aim:

The purpose of this research was to explore the breastfeeding experience of students on a university campus.

Methods:

This qualitative study used semistructured interviews. Responses were audiotaped, transcribed, and coded according to common themes using MAXQDA software.

Results:

A total of eight women were interviewed for the study. All women reported “feelings of isolation” and expressed concern over “what will others think.” In addition, “nowhere to breastfeed” and “challenges of pumping” emerged as common barriers to breastfeeding. Regrettably, “forced decisions” emerged as a major theme, with four out of eight women reporting having to supplement with formula because they returned to school.

Conclusion:

Student breastfeeding mothers are faced with emotional and physical challenges upon their return to school. Lack of space to breastfeed or pump as well as lack of support on campus are the main reasons that students stop breastfeeding prematurely. A day care facility on campus that accepts young infants, a Baby-Friendly space, and enhanced education are required to support student mothers in their choice to breastfeed.
Ebola Virus and Marburg Virus in Human Milk Are Inactivated by Holder Pasteurization
Authors: Hamilton Spence Erin , Huff Monica , Shattuck Karen , Vickers Amy , Yun Nadezda , Paessler Slobodan
Published: January 2017

Background:

Potential donors of human milk are screened for Ebola virus (EBOV) using standard questions, but testing for EBOV and Marburg virus (MARV) is not part of routine serological testing performed by milk banks.

Research aim:

This study tested the hypothesis that EBOV would be inactivated in donor human milk (DHM) by standard pasteurization techniques (Holder) used in all North American nonprofit milk banks.

Methods:

Milk samples were obtained from a nonprofit milk bank. They were inoculated with EBOV (Zaire strain) and MARV (Angola strain) and processed by standard Holder pasteurization technique. Plaque assays for EBOV and MARV were performed to detect the presence of virus after pasteurization.

Results:

Neither EBOV nor MARV was detectable by viral plaque assay in DHM or culture media samples, which were pasteurized by the Holder process.

Conclusion:

EBOV and MARV are safely inactivated in human milk by standard Holder pasteurization technique. Screening for EBOV or MARV beyond questionnaire and self-deferral is not needed to ensure safety of DHM for high-risk infants.
Maternal Employment: Enabling Factors in Context
Authors: Dotti Sani Giulia M , Scherer Stefani
Published: January 2017

Maternal employment is still below the overall EU recommended level of 60% in many European countries. Understanding the individual, household and contextual circumstances under which mothers of children of different ages are likely to be employed is crucial to develop strategies capable of increasing maternal employment. This article takes a comparative approach to investigating the characteristics associated with maternal employment in the presence of children aged 0–2, 3–5, 6–9 and 10–12 years. We model the probability of being employed full-time, part-time or being a homemaker using EU-SILC data (2004 to 2007) from Germany, Italy, Norway and the United Kingdom – four countries belonging to different gender and welfare regimes. The results indicate that individual and household characteristics are more relevant in determining mothers’ employment in countries where the state is less supportive towards maternal employment: Italy and to a lesser extent Germany and the UK – for the period observed.
Friction and wear properties of poly(ether sulfone) containing perfluorocarbon end group
Authors: Zhu Ye , Shang Yingshuang , Zhang Haibo , Ding Lianjun , Zhao Yunping , Han Yuntao , Jiang Zhenghua
Published: January 2017

Poly(ether sulfone) (PES) with high coefficient of friction (COF) and wear rate needs treatment to enhance its tribological property in engineering plastic area. Here, the low surface energy of perfluorocarbon chains terminated poly (ether sulfone) (PES-F) had been used to improve the tribological property of such self-lubricating materials. In this research, the performance enhancement due to the existence of perfluorocarbon group on the material surface was discussed on improvement of anti-friction and wear resistance. On the premise of mechanical strength guarantee, the variation regularity of COF and volume wear rate of PES-F were quantitatively analyzed through the pin-on-disc wear test apparatus, combined with X-ray photoelectron spectroscopy analysis. It was found that PES-F exhibited the best tribological property during the initial phases of friction test, attributing to the highest content of F on the material surface. Observation of PES-F worn surface and wear debris revealed that the COF and wear rate of modified PES were decreased not only due to the effect of perfluorocarbon group but also by the change of worn surface morphology, both of which were the main reasons for anti-friction and anti-wear property enhancement.
Effects of the turbulence model and the spray model on predictions of the n-heptane jet fuel–air mixing and the ignition characteristics with a reduced chemistry mechanism
Authors: Wei Haiqiao , Chen Xi , Zhao Wanhui , Zhou Lei , Chen Rui
Published: January 2017

Reynolds-averaged Navier–Stokes simulations with an improved spray model and a realistic chemistry mechanism are performed for turbulent spray flames under diesel-like conditions in a constant-volume chamber. Comprehensive numerical analyses including two turbulence models (the renormalisation group k– ε model and the standard two-equation k– ε model) with different model coefficients are made. The distribution of the fuel mixture fractions is a very important factor affecting the combustion process. In this study, we also use the entrainment gas-jet model, modifications of the the spray model coefficient and two turbulence models to investigate extensively the influence of the gas-jet theory model on the fuel–air mixture process. First, a non-reacting case is validated by comparing the liquid-phase penetration and the vapour-phase penetration and also the mixture fractions at different axis positions. Second, approriate methods are confirmed according to accurate mixture fraction distributions to validate the combustion process. Because of the large number of species and reactions, the calculation of chemically reacting flows is unaffordable, particularly for three-dimensional simulations. Hence, the dynamic adaptive chemistry method for efficient chemistry calculations is extended in this work to reduce the computational cost of the spray combustion process when a reduced chemistry mechanism is used. The results show that, in the evaporation case, the gas-jet theory model can be used to obtain a relatively accurate fuel vapour penetration length with different influential factors and that improved numerical methods can effectively reduce the mesh dependence for the spray evaporation process. It is demonstrated that the Schmidt number Sc and the turbulence models significantly influence the mixture fraction distribution. Very good agreement with available experimental data is found concerning the ignition delay time and the flame lift-off length for different oxygen concentrations owing to the accurate fuel mixture fraction.
Investigation on the spray development, the combustion characteristics and the emissions of Fischer–Tropsch fuel and diesel fuel from direct coal liquefaction
Authors: Pei Yiqiang , Qin Jing , Dai Yuli , Wang Kun
Published: January 2017

Diesel fuel is largely consumed by transportation services, and diesel fuel from direct coal liquefaction and Fischer–Tropsch fuel have been produced as alternatives in coal-rich areas. However, the physicochemical characteristics of the two fuels are not quite the same as those of diesel fuel derived from crude oil. Therefore, the spray development, the combustion characteristics and the emissions of diesel fuel from direct coal liquefaction, Fischer–Tropsch fuel and commercial diesel fuel were studied in this paper. The spray development was investigated by using planar laser-induced fluorescence, and the results showed that the spray characteristics of coal-liquefied fuel were similar to those of commercial diesel fuel. Diesel fuel from direct coal liquefaction has a longer ignition delay and a higher heat release rate from premixed combustion than commercial diesel fuel does because of its lower cetane number at low loads. However, the same combustion characteristics with commercial diesel fuel can be achieved by mixing diesel fuel from direct coal liquefaction and Fischer–Tropsch fuel in a ratio of 3 to 1. With increasing engine load, the in-cylinder temperature and the pressure increased which reduced the effect of the cetane number on the ignition delay and the combustion process. The regulated emissions from Fischer–Tropsch fuel were the lowest of these fuels; the unregulated emissions measured by Fourier transform infrared spectroscopy, however, were slightly higher than those of the other two fuels.
The Two-Body Inversion Effect
Authors: Papeo Liuba , Stein Timo , Soto-Faraco Salvador
Published: January 2017

How does one perceive groups of people? It is known that functionally interacting objects (e.g., a glass and a pitcher tilted as if pouring water into it) are perceptually grouped. Here, we showed that processing of multiple human bodies is also influenced by their relative positioning. In a series of categorization experiments, bodies facing each other (seemingly interacting) were recognized more accurately than bodies facing away from each other (noninteracting). Moreover, recognition of facing body dyads (but not nonfacing body dyads) was strongly impaired when those stimuli were inverted, similar to what has been found for individual bodies. This inversion effect demonstrates sensitivity of the visual system to facing body dyads in their common upright configuration and might imply recruitment of configural processing (i.e., processing of the overall body configuration without prior part-by-part analysis). These findings suggest that facing dyads are represented as one structured unit, which may be the intermediate level of representation between multiple-object (body) perception and representation of social actions.
‘They are not Muslims’: A critical discourse analysis of the Ahmadiyya sect issue in Indonesia
Authors: Irawan Andi Muhammad
Published: January 2017

This article examines discourse presentations of the Ahmadiyya sect (a self-defined sect of Islam) as created in texts produced by the Islamic Defender Front ( Front Pembela Islam/the FPI). The FPI considers Ahmadiyya to be a deviant sect because the sect recognises its founder, Mirza Ghulam Ahmad, as a new prophet of Islam after Prophet Muhammad. This teaching is in sharp contradiction to the belief of the majority of Muslims who believe that Muhammad is the seal of prophethood. This study aims to reveal the discourse strategies employed and discourse topics presented by the FPI in its written and spoken texts when presenting Ahmadiyya. The data analysed are two speeches delivered and two articles written by the FPI’s chairman, Habib Rizieq Shihab. The critical discourse analysis (CDA) theoretical framework employed in this study is based on Van Dijk’s ‘ideological square’, namely positive self- and negative other presentations. The findings of the study reveal that Ahmadiyya is depicted negatively as ‘the non-believers of Islam’, ‘the hijacker of Islam’, ‘the enemy of Islam’, and ‘the traitor/betrayer of Islam’, while Shihab has portrayed the FPI as ‘the tolerant Islamic group’
Estimating marginal and incremental effects in the analysis of medical expenditure panel data using marginalized two-part random-effects generalized Gamma models: Evidence from China healthcare cost data
Authors: Zhang Bo , Liu Wei , Hu Yingyao
Published: January 2017

Conditional two-part random-effects models have been proposed for the analysis of healthcare cost panel data that contain both zero costs from the non-users of healthcare facilities and positive costs from the users. These models have been extended to accommodate more flexible data structures when using the generalized Gamma distribution to model the positive healthcare expenditures. However, a major drawback with the extended model, which is inherited from the conditional models, is that it is fairly difficult to make direct marginal inference with respect to overall healthcare costs that includes both zeros and non-zeros, or even on positive healthcare costs. In this article, we first propose two types of marginalized two-part random-effects generalized Gamma models (m2RGGMs): Type I m2RGGMs for the inference on positive healthcare costs and Type II m2RGGMs for the inference on overall healthcare costs. Then, the concepts of marginal effect and incremental effect of a covariate on overall and positive healthcare costs are introduced, and estimation of these effects is carefully discussed. Especially, we derive the variance estimates of these effects by following the delta methods and Taylor series approximations for the purpose of making marginal inference. Parameter estimates of Type I and Type II m2RGGMs are obtained through maximum likelihood estimation. An empirical analysis of longitudinal healthcare costs collected in the China Health and Nutrition Survey is conducted using the proposed methodologies.
Engineering Science Education and the Indian Institutes of Technology
Authors: Raina Dhruv
Published: January 2017

The last two decades have witnessed a revival of research interest in the Cold War, and on science during the Cold War, from a revised social theoretic perspective.1 Part of this reframing is evident in explorations of the relationship underpinning the Cold War discourse and modernisation theory. Drawing on this new turn, this article switches the register to the first decades of decolonisation, and revisits the establishment of elite institutes of engineering and engineering science, such as the Indian Institute of Technology (IIT), Mumbai, in order to understand the consequences of the entanglement of the Cold War discourse with decolonisation on higher technological education in India in the 1950s. The article argues that within the realm of technological or engineering science education, across the Cold War divide, the globalisation of higher technological education or the ‘Americanization of higher education’ as Krige calls it, is evident, as much at the elite IITs in India as elsewhere.
Mother Tongue in Indigenous Script as Medium of Instruction
Authors: Das Ruchira
Published: January 2017

Olchiki is the indigenous script of Santals, a dominant tribal community of West Bengal, formulated to promote and represent ‘adi’ cultural heritage and traditions in their mother tongue Santali. The script was recognised by the Government of West Bengal in 1978 and was introduced at the primary level of education. However, there have been contestations around its appropriateness as the medium of instruction for the migrant tribal community in the emerging context of the city and globalisation. These discourses have led to the formation of two distinct groups—those who support the introduction of Santali language in Olchiki as a means to formal education and those who resist usage of its script for schooling. In my article, I will present these conflicting views prevailing among the migrant Santals of a settlement called Santragachi, in Kolkata.
Return Linkages and Volatility Spillover Effect Between Stock Markets and Currency Markets
Authors: Sharma Gagan Deep , Mishra Namish
Published: January 2017

This article undertakes the analysis of volatility and volatility spillover between stock market and currency market in India. Daily closing levels of the benchmark indices are taken for the period 1 April 2003–31 December 2013. The data are analysed through unit root tests, Autoregressive Conditionally Heteroskedastic (ARCH) family models, Johansen’s cointergation test, vector error correction model and diagonal Vector Error Correction Heteroskedastic (VECH) model. The results indicate a bidirectional volatility spillover between the Indian stock market and a currency market. The findings of the study also suggest that both the markets move in tandem with each other and there is a long-run relationship between these two markets.

Authors: Faddy Steven C , McLaughlin Kevin J , Cox Peta T , Muthuswamy Senthil S
Published: January 2017

Objective:

Many models of community-based mental health crisis teams have been reported. We present our experience of an outreach team made up of a paramedic and mental health nurse.

Methods:

A proof-of-concept was conducted in Western Sydney. The primary outcome was the proportion of patients where the team were able to facilitate the most appropriate care.

Results:

Nearly 70% of patients were able to be treated outside the Emergency Department, with about two-thirds being transported directly to a mental health facility.

Conclusion:

We have demonstrated that our model of care is successful in enabling appropriate physical and mental health care for patients suffering an acute mental health crisis.
Incorporating active learning in psychiatry education
Authors: Kumar Sonia , McLean Loyola , Nash Louise , Trigwell Keith
Published: January 2017

Objective:

We aim to summarise the active learning literature in higher education and consider its relevance for postgraduate psychiatry trainees, to inform the development of a new Formal Education Course (FEC): the Master of Medicine (Psychiatry) at the University of Sydney.

Method:

We undertook a literature search on ‘active learning’, ‘flipped classroom’, ‘problem-based learning’ and ‘psychiatry education’.

Results:

The effectiveness of active learning pedagogy in higher education is well supported by evidence; however, there have been few psychiatry-specific studies. A new ‘flipped classroom’ format was developed for the Master of Medicine (Psychiatry).

Conclusions:

Postgraduate psychiatry training is an active learning environment; the pedagogical approach to FECs requires further evaluation.

Conclusions:

Current problems with forensic mental health services may be linked to historical factors.
Multiphysics circuit of a magnetostrictive energy harvesting device
Authors: Clemente Carmine S , Mahgoub Abdelmomen , Davino Daniele , Visone Ciro
Published: January 2017

Kinetic energy harvesting devices based on magnetostrictive materials are composed of several parts, for dealing with multiphysics, including mechanical, magnetic, and electric quantities. An effective method to simulate the effects of different working conditions is important to fully exploit such devices. The aim of this paper is to present an equivalent circuit that can be identified with standard measurements on the device and simulated with a standard circuit simulator, such as Spice. The circuit is a nonlinear three-port circuit, related to the mechanical, magnetic, and electrical parts of the device. Unlike many of the published papers on the subject, the magneto-mechanical modeling is quite realistic and exploits nonlinear functions and the full coupling among the involved physical quantities of the employed magnetostrictive material. The nonlinear equivalent circuit is preliminarily validated on a concept device with permanent magnets biasing on a Stress Annealed Galfenol rod. Experimental data with different resistive loads and magnetic biasing are considered and compared with simulation outputs, in terms of the RMS voltage and harvested power.
Multiphysics equivalent circuit of a thermally controlled hydrogel microvalve
Authors: Voigt Andreas , Marschner Uwe , Richter Andreas
Published: January 2017

Temperature-responsive hydrogels are polymer particles whose equilibrium size depends on the temperature of the water they are immersed in. Here we present an equivalent circuit model of a temperature-controlled microvalve based on hydrogel particles. The resulting network model consists of three physical subsystems. The thermal subsystem considers the heat capacities and thermal resistances of the layers of the valve and the coupling to the ambient environment. The polymeric subsystem describes the relaxation of the hydrogel particles to the temperature-dependent equilibrium size. The fluidic subsystem consists of the supply channel and a chamber whose cross section varies according to the size of the hydrogel particles. All subsystems are described and coupled within one single circuit. Thus the transient behavior of the valve can be calculated using a circuit simulator. Simulation results for a setup are presented and compared with experiments.
Solvothermal synthesis, characterization, and magnetorheological study of zinc ferrite nanocrystal clusters
Authors: Wang Guangshuo , Ma Yingying , Tong Yu , Dong Xufeng , Li Meixia
Published: January 2017

In this study, zinc ferrite (ZnFe2O4) nanocrystal clusters were synthesized successfully with a surfactant-assistant solvothermal method and investigated as a potential magnetorheological material. The morphology, structure, and magnetic properties of the obtained ZnFe2O4 nanocrystal clusters were investigated in detail using a scanning electron microscope, transmission electron microscope, X-ray diffraction, and superconducting quantum interference device. It was found that the ZnFe2O4 nanocrystal clusters showed well-defined shape and homogeneous dispersion with narrow size distribution of 276 nm in diameter. The field-dependent magnetization curve indicated superparamagnetic properties of as-prepared ZnFe2O4 nanocrystal clusters with saturation magnetization ( Ms) of 86.6 emu/g at room temperature. The magnetorheological fluid with 25% particle mass fraction was prepared by ZnFe2O4 nanocrystal clusters, and the corresponding magnetorheological properties were also tested using a Physica MCR301 rheometer fitted with a magnetorheological module. The prepared magnetorheological fluid changed from a liquid-like to a solid-like state under an external magnetic field, suggesting typical Bingham plastic behavior. Compared with conventional carbonyl iron particles, ZnFe2O4 nanocrystal clusters–based magnetorheological fluid showed enhanced sedimentation stability. The obtained ZnFe2O4 nanocrystal clusters are considered as an ideal candidate for magnetorheological fluid with typical magnetorheological effect as well as improved sedimentation stability.
Rereading Rosenhan
Authors: Cummins Ian
Published: January 2017

Rosenhan’s pseudopatient experiment is one of the most famous psychological studies or experiments that has ever been conducted. The experiment took place at the end of a period in the 1960s which saw the intellectual base of psychiatry and psychiatric institutions challenged. There were two parts of the experiment. The first looked at the process of the psychiatric diagnosis; the second examined the experience of patients’ on the wards. Rosenhan argued that psychiatric diagnosis is not consistently reliable and it has to be viewed as situationally and culturally specific. This is the finding that is most consistently highlighted from the work. However, this article argues that the other elements to Rosenhan’s challenge to institutionalized psychiatric care—that diagnosis is a label that shapes subsequent perceptions of behavior and that psychiatric institutions are depersonalizing—have often been overlooked. Given the current crisis in mental health-care provision, it is argued that this critique of institutional care needs to be revisited. There is a danger that failings in current mental health provision will lead to calls for a shift in the focus toward institutionalized provision of care. The lessons of Rosenhan can be used not only to counter this but also as a basis for a value-informed approach to the provision of institutionalized mental health care.
Behavioral Assessment of the Negative Emotion Aspect of Distress Tolerance: Tolerance to Emotional Images
Authors: Veilleux Jennifer C. , Pollert Garrett A. , Zielinski Melissa J. , Shaver Jennifer A. , Hill Morgan A.
Published: January 2017

The current behavioral tasks assessing distress tolerance measure tolerance to frustration and tolerance to physical discomfort, but do not explicitly assess tolerance to negative emotion. We closely evaluated the conceptual distinctions between current behavioral tasks and self-report tasks assessing distress tolerance, and then developed a new behavioral distress tolerance task called the Emotional Image Tolerance (EIT) task. The EIT task retains elements of existing behavioral tasks (e.g., indices of persistence) while augmenting the reliability and content sufficiency of existing measures by including multiple trials, including a variety of negative affect stimuli, and separating overall task persistence from task persistence after onset of distress. In a series of three studies, we found that the EIT correlated with extant behavioral measures of distress tolerance, the computerized mirror-tracing task and a physical cold pressor task. Across all of the studies, we also evaluated whether the EIT correlated with self-report measures of distress tolerance and measures of psychopathology (e.g., depression, anxiety, and binge eating). Implications for the refinement of the distress tolerance construct are discussed.
IL-10 Gene Polymorphisms and Self-Medication With Over-the-Counter Nonsteroidal Anti-Inflammatory Drugs
Authors: Walsh Stephen J.
Published: January 2017

Background:

Genetic influences on self-medication with over-the-counter (OTC) drugs merit investigation. For example, patients frequently use OTC nonsteroidal anti-inflammatory drugs (NSAIDs) to treat inflammation, but the inflammatory response is also affected by endogenous cytokines whose production varies across polymorphisms of their encoding genes. In the case of interleukin 10 (IL-10), literature suggests that a single nucleotide polymorphism (SNP) in the promoter region of the cytokine’s gene (-1082 A > G [rs1800896]) influences production with higher levels associated with G variant alleles.

Objective:

To demonstrate the feasibility of researching the role of genetics in self-medication by using existing national survey data to evaluate a possible association between OTC NSAID use and genotype at the -1082 SNP of the IL-10 gene.

Methods:

Statistical analyses were performed using data from 6,309 participants in the Third National Health and Nutrition Examination Survey (NHANES III).

Results:

OTC NSAID use (aspirin or ibuprofen) in the previous month was significantly more common among persons with AG or GG genotypes at the -1082 SNP. Odds of use consistently increased relative to the number of G alleles. This trend remained statistically significant (odds ratio = 1.14 per additional G allele, p = .02, 95% confidence interval [1.02, 1.27]) after adjustment for confounding.

Conclusions:

Analysis of population-based genetic data suggests an association between a common self-medication behavior and a specific genetic polymorphism. These findings broadly demonstrate that NHANES data provide opportunities to investigate such associations and specifically imply that potential interrelationships among OTC NSAID use, IL-10 genotype, and IL-10 cytokine levels deserve further study.
Reduced brain atrophy rates are associated with lower risk of disability progression in patients with relapsing multiple sclerosis treated with cladribine tablets
Authors: De Stefano Nicola , Giorgio Antonio , Battaglini Marco , De Leucio Alessandro , Hicking Christine , Dangond Fernando , Giovannoni Gavin , Sormani Maria Pia
Published: January 2017

Background:

Neuroimaging studies have used magnetic resonance imaging-derived methods to assess brain volume loss in multiple sclerosis (MS) as a reliable measure of diffuse tissue damage.

Methods:

In the CLARITY study ( ClinicalTrials.gov NCT00213135), the effect of 2 years’ treatment with cladribine tablets on annualized percentage brain volume change (PBVC/y) was evaluated in patients with relapsing MS (RMS).

Results:

Compared with placebo (–0.70% ± 0.79), PBVC/y was reduced in patients treated with cladribine tablets 3.5 mg/kg (–0.56% ± 0.68, p = 0.010) and 5.25 mg/kg (–0.57% ± 0.72, p = 0.019). After adjusting for treatment group, PBVC/y showed a significant correlation with the cumulative probability of disability progression (HR = 0.67, 95% CI = 0.571, 0.787; p < 0.001), with patients with lower PBVC/y showing the highest probability of remaining free from disability progression at 2 years and vice versa.

Conclusions:

Cladribine tablets given annually for 2 years in short-duration courses in patients with RMS in the CLARITY study significantly reduced brain atrophy in comparison with placebo treatment, with residual rates in treated patients being close to the physiological rates.
Re-examining the relationships among perceived quality, value, satisfaction, and destination loyalty
Authors: Hallak Rob , Assaker Guy , El-Haddad Rania
Published: January 2017

Drawing on the literature on service quality, marketing, and tourism, the present study tests a comprehensive model of the effects of perceived quality (PQ) on loyalty in the context of a tourism destination. Using a sample of 249 residents from the United Kingdom and the United States who visited Australia between 2008 and 2012, this research applies partial least squares–structural equation modeling to examine these relationships. PQ is operationalized as a multidimensional construct determined by six destination dimensions: natural and well-known attractions, variety of tourist services, quality of general atmosphere, entertainment and recreation, general environment, and accessibility. Our results support the conceptualization of PQ as a “reflective first-order, formative second-order” model (also referred to as a molar, or type II, higher order model, see Diamantopoulos A, Riefler P, and Roth KP (2008) Advancing formative measurement models. Journal of Business Research 61(12): 1203–1218). Results from this study found that the six reflective first-order dimensions of PQ form the higher (second)-order PQ construct. Moreover, PQ has a stronger effect on loyalty (both direct and indirect through satisfaction) compared to perceived value, which only exercises an indirect effect on loyalty. The study presents new insights on the operationalization of PQ and the network of causal relationships among PQ, value, satisfaction, and loyalty in tourism destinations.
Evaluating British prime ministerial performance: David Cameron’s premiership in political time
Authors: Byrne Chris , Randall Nick , Theakston Kevin
Published: January 2017

This article contributes to the developing literature on prime ministerial performance in the United Kingdom by applying a critical reading of Stephen Skowronek’s account of leadership in ‘political time’ to evaluate David Cameron’s premiership. This, we propose, better understands the inter-relationship of structure and agency in prime ministerial performance than existing frameworks, particularly those based on Greenstein’s and Bulpitt’s approaches. We identify Cameron as a disjunctive prime minister, but find it necessary significantly to develop the model of disjunctive leadership beyond that offered by Skowronek. We identify the warrants to authority, strategies and dilemmas associated with disjunctive leadership in the United Kingdom. We argue that Cameron was relatively skilful in meeting many of the challenges confronting an affiliated leader of a vulnerable regime. However, his second term exposed deep fractures in the regime, which proved beyond Cameron’s skills as a disjunctive leader.
The research needs of an ICM trainee: The RAFT national survey results and initiatives to improve trainee research opportunities
Authors: Shaw Michelle , Harris Benjamin , Bonner Stephen
Published: January 2017

Research is key to intensive care practice but it is not certain whether trainees get the research experience they want to prepare them for clinical practice as consultants. We distributed a survey via Research & Audit Federation of Trainees to 478 current intensive care medicine trainees to establish their views. We restricted analysis to regions with an 80% or greater response rate ( n = 235 responses) to reduce self-selection bias. Our results indicated that the desire for research activities was high but multiple barriers exist. We suggest simple initiatives combined with engagement of trainee research networks and local Clinical Research Networks to improve trainee access to research opportunities. Greater freedom to participate in research activities could be created by broader ARCP clinical governance requirements, flexible interpretation of the FICM curriculum and support of trainees wishing to use their non-clinical time for projects. A resource detailing local research activity and appropriate contacts could help trainees plan suitable activities.
The Problem of Tragedy and the Protective Frame
Authors: Hick Darren Hudson , Derksen Craig
Published: January 2017

We explore the classical philosophical problem of the “paradox of tragedy”—the problem of accounting for our apparent pleasure in feeling pity and terror as audiences of staged tragedies. After outlining the history of the problem in philosophy, we suggest that Apter’s reversal theory offers great potential for resolving the paradox, while explaining some of the central intuitions motivating philosophical proposals—an ideal starting point to bridge a narrowing gap between philosophy and psychology.
Transformative Events: Appraisal Bases of Passion and Mixed Emotions
Authors: Roseman Ira J.
Published: January 2017

Mixed emotions are conceptualized as involving the co-occurrence of states opposite in valence. One might expect that combinations of opposites would show diminished overall emotion intensity. But is this always the case? If not, when will mixed emotions be characterized by high intensity, and when by low intensity? In this article, theories of emotion-eliciting appraisal and emotion intensity are employed to understand mixed emotions and phenomena of passion. It is proposed that intense emotions are produced by transformative events: perceived motive-relevant changes that are important, large, and rapid. Transformative events that can move a person between greatly motive-inconsistent and greatly motive-consistent outcomes constitute one potent path to passion. Illustrative phenomena of passion, mixed emotions, and related research are discussed.
Theoretical Conversation and Conceptual Transplants Between Economics and Systems Theory: Towards an Interpretative Passe-partout of Functional Systems
Authors: Appignanesi Laura
Published: January 2017

General systems theory is based on functional differentiation and operational closure, which make autopoiesis possible. However, in the current complex framework, the model proposed by Luhmann seems to need some supplements in order to explain the evolutionary dynamics of world society. While adopting a systemic approach and using its related theoretical tools, the focus is shifted from the inside of a system to its boundaries.

The thesis proposed is the integration between the principle of functional differentiation and that of functional connectivity. To prove such an assumption and overcome the limitations of operational closure, the Luhmannian concept of ‘structural coupling’ is used, but theoretical tools borrowed from economics (trade-off, optimal point) are also employed. This interdisciplinary integration makes it possible to argue the shift of the sociological paradigm from ‘functionalism of differences’ towards ‘functionalism of links’. Constitutive and evolutionary dynamics seem to be connected with the optimum combination of the system’s openness and closure and the ability to establish intersystemic communication channels, where the latter determines resilience to the change factors of the environment. And it is this constant disposition to change that enables the reproduction of the social system.

Does Fiscal Deficit Affect Interest Rate in India? An Empirical Investigation
Authors: Rani Ritu , Kumar Naresh
Published: January 2017

Fiscal deficit above a certain limit is not good for the country because high government borrowings raise the interest rate and crowd out private investment. This article is an attempt to analyze the impact of fiscal deficit on real interest rate in India over the time period of 1980–1981 to 2013–2014. Autoregressive distributed lags bound testing approach for cointegration and vector error correction model for Granger casualty are used in a multivariate framework in which money supply and inflation are included as additional variables. Bound test results confirm the long-run equilibrium relationship among the competing variables. Further, the rate of interest and fiscal deficit are positively related with each other in long run, whereas money supply and inflation are found to be negative and statistical significant. In addition, results of vector error correction model showed that there is unidirectional causality running from inflation to real interest rate in short run. Based on the findings, it is suggested that that proper fiscal consolidation is required to control high fiscal deficit and burgeoning interest rate in India. Further, government should move from market borrowing to tax revenue to offset fiscal deficit.
