Authors: MITCHELL BRADEN L. , DAVISON KADE , PARFITT GAYNOR , SPEDDING SIMON , ESTON ROGER G. 
Published: November 2018

ABSTRACT

Purpose
This study investigated the effect of β-blockade on physiological and perceived exertion (RPE) responses during incremental treadmill exercise.

Methods
Sixteen healthy participants (n = 8 men; age, 25.3 ± 4.6 yr) performed a maximal treadmill exercise test after ingestion of 100 mg metoprolol or placebo, with a double-blind, randomized, and counterbalanced design. Heart rate (HR), ventilatory, and gas exchange variables were measured continuously, and participants reported RPE at the end of each minute. Physiological and RPE responses during each condition were compared at the ventilatory threshold (VT), respiratory compensation point, and at maximal exercise using repeated-measures ANOVA. Linear regression modeled relationships between perceived exertion and physiological variables.

Results
The HR and V˙O2 at the VT, respiratory compensation point, and maximal exercise were all significantly lower after β-blockade (P < 0.05). However, when standardized to within condition peak values, differences were no longer significant. The RPE associated with VT was higher after β-blockade (12.9 ± 1.0 vs 12.3 ± 1.2, P < 0.05) but lower at maximal exercise (19.1 ± 0.6 vs 19.4 ± 0.5, P < 0.05). Increases in RPE relative to HR were greater after β-blockade and remained significant when expressed relative to peak HR. There was no difference in the growth of the relationship between RPE and V˙O2 across conditions, although the origin of the relationship was higher with β-blockade.

Conclusions
Although β-blockade resulted in a significant reduction in exercising HR and V˙O2, the RPE for a given relative intensity remained unchanged. The relationship between RPE and V˙O2 was not affected by β-blockade. The results provide evidence that RPE is a useful and reliable measure for exercise testing and prescription in patients prescribed β-blockade therapy.

Authors: Goodwin Alexandra , Henschen Bruce L. , O'Dwyer Linda C. , Nichols Natasha , O'Leary Kevin J. 
Published: November 2018

BACKGROUNDA small subset of patients account for a substantial proportion of hospital readmissions. Programs to reduce utilization among this subset of frequently hospitalized patients have the potential to improve health and reduce unnecessary spending.PURPOSETo conduct a systematic review of interventions targeting frequently hospitalized patients.DATA SOURCESPubMed MEDLINE; Embase (embase. com); and Cochrane Central Register of Controlled Trials, January 1, 1980 to January 1, 2018.STUDY SELECTIONFour physicians screened 4762 titles and abstracts for inclusion. Authors reviewed 116 full‐text studies and included 9 meeting criteria.DATA EXTRACTIONStudy characteristics, outcomes, and details regarding interventions were extracted. Risk of bias was assessed by the Downs and Black Scale.DATA SYNTHESISOut of the nine included studies, three were randomized controlled trials, three were controlled retrospective cohort studies, and three were uncontrolled pre‐post studies. Inclusion criteria, interventions used, and outcomes assessed varied across studies. While all nine studies demonstrated reduced utilization, studies with lower risk of bias generally found similar reductions in utilization between intervention and control groups. Interventions commonly consisted of interdisciplinary teams interacting with patients across health care settings.CONCLUSIONSInterventions targeting high need, high‐cost patients are heterogeneous, with many studies observing a regression to the mean. More rigorous studies, using multifaceted interventions which can adapt to patients' unique needs should be conducted to assess the effect on outcomes relevant to both providers and patients.
Technical Note—Closed-Form Solutions for Worst-Case Law Invariant Risk Measures with Application to Robust Portfolio Optimization
Authors: Li Jonathan Yu-Meng 
Published: November 2018

Worst-case risk measures provide a means of calculating the largest value of risk when only partial information of the underlying distribution is available. For popular risk measures such as value-at-risk (VaR) and conditional value-at-risk (CVaR) it is now known that their worst-case counterparts can be evaluated in closed form when only the first two moments are known. We show in this paper that closed-form solutions exist for a general class of law invariant coherent risk measures, which consist of spectral risk measures (and thus CVaR also) as special cases. Moreover, we provide worst-case distributions characterized in terms of risk spectrums, which can take any form of distribution bounded from below. As applications of the closed-form results, new formulas are derived for calculating the worst-case values of higher order risk measures and higher order semideviation, and new robust portfolio optimization models are provided.

Published: November 2018

Background:Labour pain is subjective and multifactorial. Methods of pain relief vary among women and across cultures, but this area has been under-researched in south-eastern Nigeria.Aims:To understand women's perspectives of labour pain in order to provide a satisfying birth experience.Methods:This cross-sectional study investigated women's perspectives of labour pain and its control. A questionnaire was used to collect data from 129 women, who had given birth at least once, at two teaching hospitals in Enugu State, Nigeria.Findings:Most respondents (77.5%) rated labour pain as ‘very severe’, and 84.4% felt it should be controlled. Overall, 60.6% had heard about labour pain control and although 46.5% received some form of pain relief in their last labour, only 15.6% had a satisfactory pain relief. Nearly all (95.9%) would choose pain relief in future labour. Increasing parity significantly reduced the desire for labour pain control (P<0.05).Conclusions:Although most women wanted pain relief in labour, they had limited knowledge of possible methods. Midwives should inform women about labour pain relief methods and offer labour pain control as a right.
Action in tranquillity: Sketching martial ideation in The Grandmaster
Authors: Wong Wayne 
Published: November 2018

Abstract
This article argues that the concept of wuyi 武意 (‘martial ideation’) forms the aesthetic core of kung fu cinema. Rather than focusing on the expressive amplification of emotion, martial ideation negotiates action and stasis through stabilization and eventually reaches a state of tranquillity. In The Grandmaster (Wong, 2013), such an ideational experience is sketched through the Buddhist notion of guan 觀 (‘perspicaciousness’). Perspicaciousness is embodied by three ways of ‘seeing’ in the mise-en-scène, including ‘listening bridge’ in martial arts performance, ‘looking back’ in narrative structure and ‘visioning’ in theme. In this light, Wong’s kung fu debut treats the southern hand-to-hand combat tradition not as a spectacle, but as an embodied knowledge that links kung fu practice with Chinese aesthetics and philosophy.

Hyperbolic Unfoldings of Minimal Hypersurfaces
Authors: Lohkamp Joachim 
Published: November 2018

AbstractWe study the intrinsic geometry of area minimizing hypersurfaces from a new point of view by relating this subject to quasiconformal geometry. Namely, for any such hypersurface H we define and construct a so-called S-structure. This new and natural concept reveals some unexpected geometric and analytic properties of H and its singularity set Ʃ. Moreover, it can be used to prove the existence of hyperbolic unfoldings of H\Ʃ. These are canonical conformal deformations of H\Ʃ into complete Gromov hyperbolic spaces of bounded geometry with Gromov boundary homeomorphic to Ʃ. These new concepts and results naturally extend to the larger class of almost minimizers.
Central adrenal insufficiency: open issues regarding diagnosis and glucocorticoid treatment
Authors: Ceccato Filippo , Scaroni Carla 
Published: November 2018

Abstract

Background
Central adrenal insufficiency (CAI) is characterized by impaired adrenocorticotropin (ACTH) secretion because of a disease or injury to the hypothalamus or the pituitary, leading to a reduced cortisol production. CAI suspicion arises more frequently in patients with pituitary tumors, cranial irradiation/surgery/injury/infections, as well as after exogenous glucocorticoid withdrawal. Nevertheless, a late diagnosis is not uncommon because CAI may present with nonspecific signs or symptoms, as fatigue or hyponatremia.

Content
The PubMed database was searched (years 1980–2018), using “central adrenal insufficiency” and “ACTH deficiency” as keywords. Subsequently, reference sections of the retrieved articles were searched.

Summary
Dynamic tests are needed when morning basal cortisol levels are not sufficient to exclude or to confirm CAI. Short Synacthen Test (SST) is the most used, and Endocrine Society’s guidelines recommend a cortisol peak >500 nmol/L to exclude CAI. Despite thresholds, understanding the pretest probability of ACTH deficiency (the clinical background of the patient) is essential because the diagnostic accuracy of SST in case of a negative result is suboptimal. Glucocorticoid replacement therapy, able to replicate cortisol circadian rhythm, is required in patients with CAI; fludrocortisone treatment is not necessary. Short-acting glucocorticoid drugs (hydrocortisone or cortisone acetate) are the most used; lower doses than previously used are nowadays recommended to reduce cortisol-related comorbidities. Promising results have been obtained with modified-release hydrocortisone, especially regarding glucose metabolism in patients with primary adrenal insufficiency.

Outlook
An accurate clinical diagnosis and a careful individualized therapy are mandatory in patients with CAI.
A Context for Complexism: Between Neoliberal Social Thought and Algorithmic Art
Authors: Crano Ricky D. 
Published: November 2018

Abstract
Among the many genres of visual art to emerge in the wake of computerisation, the subset of generative or algorithmic art known as complexism seems uniquely keyed to the social and technological mainsprings of everyday life in the twenty-first century. Complexism typically deploys computer algorithms to demonstrate how complex phenomena can emerge through the reiterative enactment of simple rulesets. The light and sound installations and the videos that complexist artists produce, alongside the discourses surrounding the works, stand out as singularly contemporary, not necessarily for their exploitation of now-ubiquitous telematic tools and techniques, but for their deep commitment to the trailblazing problems, methods, and hypotheses set out by the new science of complexity. Practitioners of and commentators on complexism (the work and writings of Philip Galanter feature most prominently here) persistently invoke this booming interdisciplinary field of complexity research. Against this trend, I argue that for all the leverage the tools and terms of complexity science supply to complexist art, the concept of complexity itself remains surprisingly vague and shorn of any historical sensibility. One preliminary aim of this essay is to bring more theoretical rigour to the artists’ use of this concept by beginning to fill in the missing backstory. From there, I move to complicate this genealogy by introducing a somewhat controversial figure-the social theorist, political economist, and legal philosopher Friedrich Hayek, who had posited similar problems concerning the emergence and maintenance of complex, self-organized systems as early as the 1930s, and whose theoretical solutions to these problems were instrumental to what historians and sociologists have subsequently described as capitalism’s late “neoliberal turn.”

Abstract
A three-level finite difference scheme is studied for the initial-boundary value problem of the generalized Benjamin–Bona–Mahony–Burgers equation. The obtained algebraic equations are linear with respect to the values of the desired function for each new level. The unique solvability and absolute stability of the difference scheme are shown. It is proved that the scheme is convergent with the rate of order

Boys – the Disadvantaged Gender?
Authors: Bereswill Mechthild 
Published: November 2018

Abstract
The paper is focused on a powerful discursive configuration: the diagnosis that boys are nowadays tremendously suffering from being de-privileged in relation to girls. The hermeneutic analysis of the dominant patterns of interpretation that are characteristic for this dramatized discourse-configuration shows how the gender order of the modern society is constructed as instable and seriously endangered. The narrative pattern of the boy being fundamentally disadvantaged – not least by lacking male interfaces – is in this paper discussed as a ‘supportive narrative’ for (re)stabilizing difference and distinction within a clearly structured gender order. However, the open question will remain as to whether the overdetermination that structures the discourse as a whole points in the direction of a persisting or a changing social and symbolic order.
Federal Disputes in the German Reich under the Weimar Constitution: Lessons in Dispute Settlement for the Kingdom of the Netherlands
Authors: Hoogers Gerhard , Karapetian Gohar 
Published: November 2018

Abstract
Although the German Bundesverfassungsgericht has become one of the most famous constitutional courts in the world, there is an older, less ambitious but nonetheless interesting tradition of constitutional review in Germany. In this article an analysis will be undertaken of the functioning and case law of the Staatsgerichtshof für das deutsche Reich (RStGH), especially its case law on federal disputes, to see whether this half-forgotten court of the Weimar years could be an interesting role model for the Kingdom of the Netherlands, where the discussion on a new constitutional arrangement for the resolution of federal disputes has been paralysed for years.

Published: November 2018

Abstract
While manipulatives have played an important role in children’s mathematics development for decades, employing tangible objects together with digital systems in the classroom has been rarely explored yet. In a transdisciplinary research project with computer scientists, mathematics educators and a textbook publisher, we investigate the potentials of using tangible user interfaces for algebra learning and develop as well as evaluate a scalable system for different use cases. In this paper, we present design implications for tangible user interfaces for algebra learning that were derived from a comprehensive field study in a grade 9 classroom and an expert study with textbook authors, who also are teachers. Furthermore, we present and discuss the resulting system design.
Analysing Willerding’s formula for solving the planar three point resection problem
Authors: Heindl Gerhard 
Published: November 2018

Abstract
The main mathematical problem in the planar three point resection problem of surveying is to find a necessary and sufficient condition that a point on a plane is uniquely determined if the directions from that point to three given points are known only up to an unknown offset. It will be shown in this paper that such a condition is the applicability of Willerding’s formula for computing the point in question, and that this condition is equivalent to the well-known necessary condition that the four considered points are not located on a circle or a line. Because of this result, the easy evaluation and the short derivation of Willerding’s formula, it can be expected, that this formula will be widely used in surveying, and also for autonomous robot localization.
The Malleability of Truth and Language in Chay Yew’s Porcelain and A Language of Their Own
Authors: Ha Quan-Manh , Vigesaa Andrew 
Published: November 2018

Abstract
In Asian American literature and drama, the pursuit of identity was at the forefront of discussion for much of the twentieth century. More and more frequently Asian American voices from the LGBTQ community have addressed intersectionality in established narratives. As issues of identity and intersectionality converge, postmodernity becomes a useful lens through which to examine the elements of this task. In Chay Yew’s plays entitled Porcelain and A Language of Their Own, the status of Asian identities in the Western world is not given a sure footing, but rather it is placed in a state of confusion. In Porcelain, this confusion stems from the tension between objective truth and the postmodern phenomenon of media-fueled panic. In A Language of Their Own, similar confusion arises between the subjective and performative conveying of meaning in language. These contrasting elements serve to highlight the postmodern search for identity among Asian men living in the Western world, where the complexities of identity are compounded by the subjectivity of truth.
Response surface methodological approach for optimizing the removal of cadmium from aqueous solutions using pistachio residues biochar supported/non-supported by nanoscalezero-valent iron
Authors: Saffari Mahboub 
Published: November 2018

Abstract
A three-level Box–Behnken model (BBM) under response surface methodology (RSM) was used to optimize the removal of cadmium (Cd) ion by pistachio residues biochar (PRB) and PRB supported by nanoscale zero-valent iron (PRB-nZVI) from aqueous solutions. Optimization experiments were carried out by evaluation of the effect of four variables (initial Cd concentration, initial solution pH, adsorbent dosage, and contact time) at three levels (high, medium, and low), and one category contained two variables (PRB and PRB-nZVI). For this purpose, a total of 58 experimental runs were set and the experimental data were fitted to the empirical second-order polynomial model of a suitable degree. The physical and chemical structure results of the adsorbents confirmed the formation of nZVI (with diameters ~35 nm) on the PRB surface. The results showed that the new composite of biochar (PRB-nZVI) exhibited higher Cd removal efficiency compared with PRB from aqueous solutions. The existence of functional groups and nZVI on the surface of PRB-nZVI could be better than PRB for Cd removal in aqueous solutions by the processes of sorption, precipitation, and co-precipitation. Numerical optimization revealed that the optimum removal (96.58%) was obtained at an initial Cd concentration of 25.99 mg L−1 (pH 6.58), adsorbent dose (PRB-nZVI) of 0.55 g L−1, and contact time of 34.11 min, with desirability of 1. Based on the results, it is recommended that PRB-nZVI can be effectively used for the removal of Cd from a contaminated aqueous solution with varying chemical and physical conditions.
