Authors: Lu Chun‐Kuan , Fu Yin‐Chih , Cheng Yuh‐Min , Huang Peng‐Ju 
Published: June 2014

AbstractThis study aims to describe the clinical results of isolated talonavicular arthrodesis in rare Müller‐Weiss disease, spontaneous osteonecrosis of the navicular in adults. From June 2001 to April 2010, we performed isolated talonavicular arthrodesis on 13 feet of 13 patients (mean age: 55.6 years) with Müller‐Weiss disease. The feet were staged by the preoperative radiographs according to the Maceira classification. The average modified American Orthopaedic Foot and Ankle Society (AOFAS) ankle‐hindfoot score improved from 48.5 points preoperatively to 87.2 points at final follow‐up (mean 51 months, range 10–114 months). Union was achieved in 10 cases (76.9%). If the subtalar and calcaneocuboid joints are relatively healthy, isolated talonavicular arthrodesis may be an effective and reliable surgical option for treatment of Müller‐Weiss disease that is resistant to conservative treatment.
ON SOME PROPERTIES OF TWO VECTOR-VALUED VAR AND CTE MULTIVARIATE RISK MEASURES FOR ARCHIMEDEAN COPULAS
Authors: Hürlimann Werner 
Published: June 2014

AbstractWe consider the multivariate Value-at-Risk (VaR) and Conditional-Tail-Expectation (CTE) risk measures introduced in Cousin and Di Bernardino (Cousin, A. andDi Bernardino, E. (2013)Journal of Multivariate Analysis,119, 32–46;Cousin, A. andDi Bernardino, E. (2014)Insurance: Mathematics and Economics,55(C), 272–282). For absolutely continuous Archimedean copulas, we derive integral formulas for the multivariate VaR and CTE Archimedean risk measures. We show that each component of the multivariate VaR and CTE functional vectors is an integral transform of the corresponding univariate VaR measures. For the class of Archimedean copulas, the marginal components of the CTE vector satisfy the following properties: positive homogeneity (PH), translation invariance (TI), monotonicity (MO), safety loading (SL) and VaR inequality (VIA). In case marginal risks satisfy the subadditivity (MSA) property, the marginal CTE components are also sub-additive and hitherto coherent risk measures in the usual sense. Moreover, the increasing risk (IR) or stop-loss order preserving property of the marginal CTE components holds for the class of bivariate Archimedean copulas. A counterexample to the (IR) property for the trivariate Clayton copula is included.
Application of image processing based on multiple filters in an alignment system

Abstract
Beam alignment depends on CCD real-time image analysis and processing. In order to improve the quality of the alignment, multiple filters are used in far-field and near-field image processings. These multiple filters are constituted of an average filter and a median filter in different connection sequences, so that they can deal with different kinds of noise. To reduce the effect of the unknown nonlinear relationship between motor running steps and deviation pixels, a feasible methodology is offered to improve this phenomenon and a fuzzy algorithm is applied to the motor feedback control process. Because of the fuzzy control it is not necessary to establish an accurate mathematical model, so the impact of the nonlinear relationship will be reduced.
Steady water waves with vorticity: an analysis of the dispersion equation
Authors: Kozlov V. , Kuznetsov N. , Lokharu E. 
Published: June 2014

AbstractTwo-dimensional steady gravity waves with vorticity are considered on water of finite depth. The dispersion equation is analysed for general vorticity distributions, but under assumptions valid only for unidirectional shear flows. It is shown that for these flows (i) the general dispersion equation is equivalent to the Sturm–Liouville problem considered by Constantin & Strauss (Commun. Pure Appl. Math., vol. 57, 2004, pp. 481–527; Arch. Rat. Mech. Anal., vol. 202, 2011, pp. 133–175), (ii) the condition guaranteeing bifurcation of Stokes waves with constant wavelength is fulfilled. Moreover, a necessary and sufficient condition that the Sturm–Liouville problem mentioned in (i) has an eigenvalue is obtained.
Gastric emptying is involved inLactobacilluscolonisation in mouse stomach

Published: June 2014

Lactobacilli are indigenous microbes of the stomach of rodents, with much lower numbers being present in mice fed a purified diet than in those fed a non-purified diet. We postulated that gastric emptying (GE) is responsible for the different colonisation levels of lactobacilli and tested this hypothesis in the present study. BALB/cCr Slc mice were fed either a non-purified diet or a purified diet for 2 weeks. The number of gastric tissue-associated lactobacilli was lower in mice fed the purified diet than in those fed the non-purified diet. GE, estimated by measuring the food recovered from the stomach, was higher in mice fed the purified diet than in those fed the non-purified diet and correlated negatively with the number of lactobacilli. Mice fed the non-purified diet exhibited lower GE rates even when lactobacilli were eliminated by ampicillin administration through the drinking-water, suggesting that GE is the cause but not the consequence of differentLactobacilluscolonisation levels. The plasma concentrations of acylated ghrelin, a gastric hormone that promotes GE, were higher in mice fed the purified diet than in those fed the non-purified diet. There was a negative correlation between GE and the number of lactobacilli in mice fed the non-purified diet, the purified diet, and the purified diet supplemented with sugarbeet fibre (200 g/kg diet) or carboxymethyl cellulose (40 g/kg diet). We propose that a higher GE rate contributes, at least in part, to lower gastric colonisation levels of lactobacilli in mice fed a purified diet.

Dairy products derived from the milk of cows fed in pastures are characterised by higher amounts of conjugated linoleic acid and α-linolenic acid (ALA), and several studies have shown their ability to reduce cardiovascular risk. However, their specific metabolic effects compared with standard dairy in a high-fat diet (HFD) context remain largely unknown; this is what we determined in the present study with a focus on the metabolic and intestinal parameters. The experimental animals were fed for 12 weeks a HFD containing 20 % fat in the form of a pasture dairy cream (PDC) or a standard dairy cream (SDC). Samples of plasma, liver, white adipose tissue, duodenum, jejunum and colon were analysed. The PDC mice, despite a higher food intake, exhibited lower fat mass, plasma and hepatic TAG concentrations, and inflammation in the adipose tissue than the SDC mice. Furthermore, they exhibited a higher expression of hepaticPPARαmRNA and adipose tissue uncoupling protein 2 mRNA, suggesting an enhanced oxidative activity of the tissues. These results might be explained, in part, by the higher amounts of ALA in the PDC diet and in the liver and adipose tissue of the PDC mice. Moreover, the PDC diet was found to increase the proportions of two strategic cell populations involved in the protective function of the intestinal epithelium, namely Paneth and goblet cells in the small intestine and colon, compared with the SDC diet. In conclusion, a PDC HFD leads to improved metabolic outcomes and to a stronger gut barrier compared with a SDC HFD. This may be due, at least in part, to the protective mechanisms induced by specific lipids.
Long-term intake of soyabean phytosterols lowers serum TAG and NEFA concentrations, increases bile acid synthesis and protects against fatty liver development in dyslipidaemic hamsters

Published: June 2014

Various human trials and pre-clinical studies have suggested that dietary plant sterols possess hypotriacylglycerolaemic properties apart from their cholesterol-lowering properties. We hypothesised that phytosterols (PS) might attenuate triacylglycerolaemia by interfering with the deleterious effects of cholesterol overload in the liver. In the present study, twenty hamsters (Mesocricetus auratus) with diet-induced combined hyperlipidaemia were fed a high-fat diet (HFD,n10) or a HFD supplemented with soyabean PS (n10) for 40 d. In parallel, a healthy group was fed a standard diet (n10). PS normalised fasting plasma cholesterol concentrations completely after 20 d and were also able to normalise serum TAG and NEFA concentrations after 40 d. HFD feeding caused microvesicular steatosis and impaired the expression of key genes related to fatty acid oxidation such asPPARA, carnitine palmitoyltransferase-Iα (CPT1A) and phosphoenolpyruvate carboxykinase 1 (PCK1) in the liver. PS treatment completely protected against HFD-induced steatosis and resulted in a normalised hepatic gene expression profile. The protection of the hepatic function by PS was paralleled by increased faecal cholesterol excretion along with a 2-fold increase in the biliary bile acid (BA):cholesterol ratio. The present study supports the conclusion that long-term consumption of PS can reduce serum TAG and NEFA concentrations and can protect against the development of fatty liver via different mechanisms, including the enhancement of BA synthesis. The results of the present study place these compounds as promising hepatoprotective agents against fatty liver and its derived pathologies.
OVERWEIGHT/OBESITY AND HUMAN CAPITAL FORMATION FROM INFANCY TO ADOLESCENCE: EVIDENCE FROM TWO LARGE US COHORTS
Authors: MURASKO JASON E. 
Published: June 2014

SummaryBody mass index (BMI) levels in US children and adolescents have increased over the past several decades. The negative health effects of this trend are well-documented. Recent work has evaluated the potential effects on skills formation. Studies are mixed on whether there is an association between high BMI and skills outcomes, and those that estimate causal effects find none. This paper offers estimates on the causal effect of BMI-defined overweight and obesity on skills formation using two large cohorts of contemporary US children followed from infancy to 5 years and from kindergarten (6 years) to the eighth grade (14 years). Significant negative associations were observed in the random effects models for males in early life with respect to a mental skills assessment, for females during the pre-school years for reading and maths assessments, for both males and females during the schooling years for reading assessments and for females during the schooling years for maths assessments. Fixed effects models yielded a significant negative association only with respect to the latter. The implication of these findings is that any improvement in skills outcomes that may accompany reductions in obesity prevalence may depend on whether interventions are general to overall health productivity or whether they are specific to dietary and exercise behaviours.
Evaluation of a temporal bone prototype by experts in otology
Authors: Chenebaux M , Lescanne E , Robier A , Kim S , Bakhos D 
Published: June 2014

AbstractBackground:Inexperienced otologists require training on the temporal bone drilling process, prior to any surgical activity. The shortage of cadaveric temporal bones exerts pressure to create realistic physical prototypes. This paper describes the evaluation by otology experts of a specially developed temporal bone resin model.Methods:Computed tomography images were transformed into digital files, and anatomically identical right temporal bone models were created using stereolithography. These hand-painted resin prototypes were sent to 25 otologists, accompanied by a 20-item questionnaire.Results:Satisfaction rate was 92 per cent. The overall prototype score was 48.87 out of 60. Average scores were: 12.63 out of 15 for anatomy-morphology, 6.98 out of 9 for quality of drilling, 16.74 out of 21 for identification of anatomical elements and 7.41 out of 9 for stages of drilling. Limitations of the model included an excessively vivid facial nerve colour and difficulty in identifying the posterior semicircular canal. Disadvantages related to the thickness of the resin and its residues were identified.Conclusion:The prototype appears to provide an attractive solution to the shortage of cadaveric temporal bones. However, interest in the model for drilling technique training for inexperienced otologists has not yet been assessed.
PERFORMING THE PATRON: BETTY FREEMAN AND THE AVANT-GARDE
Authors: Johnson Jake 
Published: June 2014

AbstractLittle can be said about music during the last century without encountering the men and women who supported it financially. Pierre Bourdieu's impression that the services rendered freely for the good of society reinforce a symbolic debt between giver and recipient complicates motivations behind patronage. Indeed, applying Bourdieu's theory to altruism in general – here, patronage in particular – highlights what could be thought of as a performance of futility: both giver and receiver understand the tenacious terms yet agree nonetheless to act out the process of reaching equilibrium. In the case of iconic music patron Betty Freeman (1921–2009), her support of the avant-garde seems, at times, to call into question on what side of this ‘performed futility’ she existed. This article considers ways in which Freeman's work as patron of the musical avant-garde allowed her to perform her identity as a woman and mother among a community on the fringe.
Collective Protection for New Social Risks: Childcare and the Dutch Welfare State
Authors: YERKES MARA A. 
Published: June 2014

AbstractIssues such as caring and family policy have received increased attention within the sociological literature on the welfare state during the past decades. At the same time, there has been much debate about the protection of social risks. In particular, scholars have questioned the ability of welfare states to respond to so-called new social risks, such as reconciling work and care. The literature on new social risks assumes welfare states will have difficulty addressing these risks due to pressures for reform and assumed individual responsibility for new social risks. In contrast, the Dutch welfare state has been successful in re-orienting existing institutions to develop a semi-collectivised yet market-driven form of childcare policy. Using qualitative interview data and document analysis, this article analyses the development of Dutch childcare policy from 1995 to 2009. The development of childcare policy is attributed to three social mechanisms: a common perception among actors viewing childcare as a solution to improve women's employment; a party politics mechanism, which creates a distinct Dutch approach to childcare; and a corporatist mechanism, referring to the interaction between the state and industrial relations, which failed in the area of childcare policy. The development of childcare policy has not been wholly unproblematic, however, and therefore a critical discussion of these developments is offered. Also, an update of policy developments through to 2013 is provided.
The Princely Republic
Authors: Stacey Peter 
Published: June 2014

AbstractThis article examines Seneca's theory of monarchy inDe clementia. It focuses in particular on Seneca's appropriation and redefinition of some key terms within Roman political thought in order to present his theory as an account of the restitution of liberty to theres publicaunder the government of the virtuousprinceps. By relocating the Roman body politic to a Stoic moral universe, Seneca is able to draw upon parts of his philosophical inheritance in order to substantiate his claim in some depth.
Institutions and coalitions in policy processes: a cross-sectoral comparison
Authors: Fischer Manuel 
Published: June 2014

AbstractActors with joint beliefs in a decision-making process form coalitions in order to translate their goals into policy. Yet, coalitions are not formed in an institutional void, but rather institutions confer opportunities and constraints to actors. This paper studies the institutional conditions under which either coalition structures with a dominant coalition or with competing coalitions emerge. It takes into account three conditions, i.e. the degree of federalism of a project, its degree of Europeanisation and the openness of the pre-parliamentary phase of the decision-making process. The cross-sectoral comparison includes the 11 most important decision-making processes in Switzerland between 2001 and 2006 with a fuzzy-set Qualitative Comparative Analysis. Results suggest that Europeanisation or an open pre-parliamentary phase lead to a dominant coalition, whereas only a specific combination of all three conditions is able to explain a structure with competing coalitions.
Modelling disparities in health services utilisation for older Blacks: a quantile regression framework
Authors: SHARMA ANDY 
Published: June 2014

ABSTRACTWith the on-going ageing of the United States population, resolving health disparities continues to be a prominent and worthwhile goal, particularly in the areas of promoting minority health and reducing racial/ethnic disparities. This analysis employs the 2004 and 2005 Household Component records from the Medical Expenditures Panel Survey, which correspond to data files H89 and H97, to examine utilisation by race across the entire distribution function; more specifically, applying the behavioural model of health services utilisation and employing a Quantile Regression (QR) framework. This is a noteworthy contribution because the conditional mean may not be the best approximation for a skewed-location distribution. In contrast, QR is robust to outliers and scale effects since the estimation minimises least absolute deviation. The sample consists of 2,525 older adults at least 65 years of age with 303 corresponding to Black and 2,222 corresponding to White. Results suggest older Blacks continue to utilise health services (i.e. office or clinic visits with a physician or medical provider) at lower levels and this is more pronounced at and below the median quantile (i.e. below the 50th cut-off). Usual source of care (USC) continues to play an important role. Beliefs surrounding the need for insurance and medical intervention are also significant and explain some of the racial disparities. Although utilisation disparities persist for older Blacks, collaborative and flexible models of care can reach this group.

SUMMARYFor decades, vaccination with the 23-valent polysaccharide pneumococcal vaccine (PPV23) has been available for risk groups aged ⩾2 years to prevent invasive pneumococcal disease (IPD). Recently, a 13-valent pneumococcal conjugated vaccine (PCV13) has been licensed for use in all age groups. PCV13 may induce better protection than PPV23 because of different immunogenic properties. This called for a revision of vaccine recommendations for risk groups. We therefore reviewed literature on risk groups for IPD, and effectiveness and safety of pneumococcal vaccines and supplemented that with information from public health institutes, expert consultations and data on IPD epidemiology. We included 187 articles. We discuss the implications of the heterogenic vulnerability for IPD within and between risk groups, large indirect effects of childhood immunization, and limited knowledge on additional clinical benefits of PCV13 in combination with PPV23 for the Norwegian recommendations. These are now step-wise and consider the need for vaccination, choice of pneumococcal vaccines, and re-vaccination interval by risk group.

SUMMARYEating raw pork and/or liver is a custom of the Bai ethnic group in China. Most people living in Dali Bai Autonomous Prefecture, Yunnan Province, southwestern China are of Bai ethnicity. Little is known of the seroprevalence ofToxoplasma gondiiin Bai and Han ethnic populations in this region. In the present survey, a total of 555 and 595 blood samples were obtained from Bai and Han ethnic groups in Dali urban and rural areas, respectively. Enzyme-linked immunosorbent assay was performed to examineT. gondiiIgG antibodies. Total positive rate of anti-T. gondiiIgG in Bai and Han groups in this region was 21·6% (248/1150). The total seroprevalence ofT. gondiiwas significantly higher in the Bai ethnic group (32·3%, 179/555) than in the Han ethnic group (11·6%, 69/595) (P < 0·01). The results of statistical analysis indicated that there was no significant difference between cat feeding/non-cat feeding groups in the Bai ethnic group, the most important risk factor was consumption of raw pork and/or liver for the Bai group, but feeding a cat may be the main route ofT. gondiiinfection for the Han group. Therefore, it is essential to implement integrated strategies to prevent and controlT. gondiiinfection in this unique region of the world.
(r) we there yet? The change to rhoticity in New York City English
Authors: Becker Kara 
Published: June 2014

AbstractLabov (1966, 1972b) described the variable production of coda /r/ in New York City English (NYCE) as a change in progress from above in the direction of rhoticity. Since then, scholars have commented on the slow rate of change toward rhoticity in NYCE and characterized (r) as a superposed feature restricted to formal speech (Fowler, 1987; Labov, 1994; Labov, Ash, & Boberg, 2006). This study's ethnically diverse sample of speakers from the Lower East Side of Manhattan (n = 65) shows a mean rate of /r/ production of 68%, with young people, women, and middle-class speakers leading in the production of /r/ in apparent time. Speakers from five ethnic backgrounds—African American, Chinese, Jewish, Puerto Rican, and white—show coherence for the internal constraints on variable nonrhoticity. However, only Chinese, Jewish, and white speakers participate in the change toward rhoticity. These findings highlight the role of ethnicity in patterns of variation and change and demonstrate that the change toward rhoticity in NYCE has accelerated and is no longer restricted to formal speech.
