Single and Multisettlement Approaches to Market Clearing Under Demand Uncertainty
Authors: Khazaei Javad , Zakeri Golbon , Oren Shmuel S. 
Published: June 2017

Participants in electricity markets face a substantial amount of uncertainty, and with increased penetration of volatile renewable generation this uncertainty has further increased. Conventionally designed electricity markets cope with uncertainty by running two markets: a market that is cleared ahead of time, followed by a real-time balancing market to reconcile actual realizations of demand and available generation. In such mechanisms, the initial clearing process does not take into account the distribution of outcomes in the balancing market. Recently, an alternative so-called stochastic settlement market has been proposed (see, e.g., Pritchard et al. 2010 [Pritchard G, Zakeri G, Philpott A (2010) A single-settlement, energy-only electric power market for unpredictable and intermittent participants. Oper. Res. 58(4):1210–1219.] and Bouffard et al. 2005 [Bouffard F, Galiana FD, Conejo AJ (2005) Market-clearing with stochastic security—Part I: Formulation. IEEE Trans. Power Systems 20(4):1818–1826.]) where the ISO clears both stages in one single settlement market. While the effectiveness of the stochastic market clearing mechanism is clear when the market is competitive, this is open to question for imperfectly competitive markets. In this paper we consider simplified models for two types of market clearing mechanisms. First, a market clearing mechanism utilized in New Zealand, whereby firms offer in advance and are notified of a clearing quantity and price guide based on an estimate of demand, followed by real-time dispatch. We refer to this as NZTS. Secondly we consider a simplified stochastic programming market clearing mechanism. We compute Nash equilibria of games resulting from each of the market clearing mechanisms. We prove that under the assumption of symmetry, our simplified stochastic programming market clearing is equivalent to a two-period single settlement system that takes account of deviation penalties in the second stage. These, however, differ from NZTS. We show that when we assume symmetry, this stochastic settlement model results in better social welfare than does NZTS. We also investigate a number of asymmetric examples numerically. The e-companion is available at https://doi.org/10.1287/opre.2017.1610 .
Kaolinite Aggregation in Book-Like Structures from Non-Aqueous Media
Authors: Mansa Rola , Ngassa Piegang Guy B. , Detellier Christian 
Published: June 2017

AbstractTo control a vast spectrum of applications and processes, an understanding of the morphologies of clay mineral assemblies dispersed in aqueous or non-aqueous media is important. As such, the objective of this study was to verify the relationship between dispersion medium type and the size and morphology of the clay aggregates that are formed, which can increase knowledge on the assembly formation process. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectroscopy were used in an attempt to describe kaolinite platelet organization in non-aqueous media and to compare it to the organization in aqueous media or in media with or without a selection of dissolved organic polymers. The SEM images indicated that the kaolinite platelet assembly process occurs during slow evaporation of the solvent. Because the experimental procedure was rigorously identical for all cases in this study, the SEM images compared how the effects of various media and environments on kaolinite platelet interactions can lead to different morphologies. Quite spectacular morphological differences were indeed observed between samples dispersed in aqueous and non-aqueous media, particularly when the kaolinite platelets were dispersed in an organic solvent with dissolved organic polymers. For kaolinite dispersed in water, only small aggregates were observed after slow evaporation. In contrast, large kaolinite booklets or vermiform aggregates were formed by slow solvent evaporation when kaolinite was first dispersed into some organic solvents. The aggregates were particularly large when an organic polymer was dissolved in the organic solvent. For example, kaolinite aggregates dispersed in a binary cyclohexane/toluene mixture with dissolved ethyl cellulose (EC) had top apparent surface areas (i.e. stacking length × width) of more than 3,000 µm2. Other dissolved polymers, such as polystyrene or the polysaccharide, guar gum, gave similar results. Kaolinite platelet aggregation resulted from face-to-face interactions as well as edge-to-face and edge-to-edge interactions. The XRD results showed that ethyl cellulose led to the formation of smaller kaolinite platelets with an increased tendency to form larger aggregates, which is due to the ability of EC to chemically interact with silanol and/or the aluminol groups of kaolinite.
The way to a heart: Food for love
Authors: Wessell Adele 
Published: June 2017

Abstract
The connection established between pleasure and food has a long history in recipes for love. Cooking literature has reflected and shaped our ideas about home cooking as well as romance and can be read as a historical source for understanding those ideas as they were expressed in the past and in terms of what has endured over time. Considering cooking as a language that expresses love advances our understanding of the preparation of food as an emotional performance. The way to a heart, like love itself, is also historical rather than timeless. The shift in focus from advice to single women on how to win a man, to the newlywed on culinary skills to ensure a happy married life through to blogs promoting food as seduction, highlight changes in gender roles and sexuality that reinforce the significance of culinary literature as examples of material culture that reflect their time and place and the changing meanings of home cooking and love.
Verdadeiro ou Falso? A ambiguidade de uma lista de frases permite o estudo de processos de atribuição de verdade
Authors: Garcia-Marques Teresa , Silva Rita R. , Mello Joana 
Published: June 2017

Neste artigo são apresentados os dados de dois pré-testes realizados a diversas frases que representam conhecimentos mundanos. As frases foram pré-testadas relativamente à dimensão subjectiva de verdade junto de amostras da população Portuguesa aplicando dois critérios diferentes. No primeiro pré-teste as avaliações de conjunto de afirmações verdadeiras foram contrastadas com as avaliações feitas de afirmações falsas obtidas por alteração de um pequeno detalhe da frase original. No segundo pré-teste um outro conjunto de frases foi avaliada apenas na sua versão verdadeira ou na sua versão falsa numa escala dicotómica de “verdadeiro ou falso”. Os resultados salientam as frases consideradas ambíguas e a sua relevância para a investigação de enviesamentos de percepção de verdade. Adicionalmente, algumas das frases ambíguas apresentadas foram testadas relativamente ao grau de “divertimento” que promovem com o objectivo de permitir o controlo de efeitos afectivos nos seus julgamentos.

Published: June 2017

No âmbito da prestação de serviços de saúde, especialmente, em contexto oncológico, a associação entre motivação e satisfação no trabalho torna-se saliente. Partindo do instrumento de avaliação da motivação para o trabalho desenvolvido por Paleologou, Kontodimopoulos, Stamoli, Aletras e Niakas (2006), este estudo pretende, por um lado, avaliar a qualidade psicométrica deste instrumento, a sua estrutura fatorial, confiabilidade e validade numa amostra de profissionais de saúde de um hospital oncológico português. Por outro lado, pretende-se investigar os componentes da motivação que melhor predizem a satisfação no trabalho. Os scores dos quatro fatores do instrumento de motivação para o trabalho apresentaram boa consistência interna (α’s=> .96). Os resultados da análise fatorial exploratória revelaram uma estrutura fatorial composta por18 itens distribuídos por quatro fatores, adequada aos dados correlacionais (e ao construto teórico subjacente à escala) e com garantias de fiabilidade e validade. A correlação de Pearson com a medida de satisfação com o trabalho faculta evidência acerca da validade convergente do instrumento de motivação para o trabalho. O modelo de regressão múltipla identifica os fatores job attributes, remuneration e achievements como preditores significativos da satisfação no trabalho.
Vergangene Vergängnis: Für eine Philologie des Stattdessen
Authors: Cho Hyowon 
Published: June 2017

Abstract
Between Erich Auerbach and Walter Benjamin, there existed a remarkable friendship, which on the one hand manifested itself as an unobtrusive disputation, and yet which on the other hand could be considered an unintended collaboration toward an old-new ideal of philology. Auerbach claims that with the Divine Comedy of Dante Alighieri, Western European literature reached the climax of the figuralism that Auerbach, if belatedly, wants to bring to the fore. Benjamin, in contrast, finds energy for the revolution in the surrealistic love that traces back not to Dante, but to the Provençal poetry which Auerbach regards merely as preliminary to Danteʼs literary achievement. In his The Origin of German Tragic Drama, Benjamin highlights the concept of creatureliness, whose significance for his philosophy of history is no less than that of justice. Auerbach, for his part, does not find its expression in the Germany of the 17th century, but in the France of the 16th century, namely in the work of Michel de Montaigne. However, Montaigneʼs creatureliness is rooted in sermo humilis, which is best embodied in the story of Peter who denied his Lord Jesus Christ three times. By contrast, German creatureliness detects its dissolution in the idea of natural theatre that Benjamin locates in the work of Franz Kafka. Sermo humilis is the perfection of figuralism, whereas the idea of natural theatre means reversal of allegory. The perfected figuralism and the reversed allegory cooperate in the idea of the philology of instead (Philologie des Stattdessen), whose task it is to make bygone the futility of worldly things.
The Iniquity of Money-Metric Poverty in India
Authors: Jayaraj D , Subramanian S 
Published: June 2017

Abstract
This paper is concerned to make three points about money-metric poverty in India: first, that the standard poverty-line approach to measuring poverty considerably underestimates poverty, and that the particular protocols by which India’s official poverty lines are determined are arbitrary and misleading; second, that a view of poverty in which the achievement of a satisfactory level of income is seen as a valuable end in itself, and which is captured in something like Kaushik Basu’s ‘quintile income statistic’, suggests a high order of income-poverty in the country which belies the relatively encouraging trends exhibited by headcount ratios based on official poverty lines; and third, that the continued co-existence of large amounts of poverty with large amounts of inequality needs to be redeemed by some deliberate redistributive strategy aimed at providing something like a guaranteed basic minimum income to every citizen of the country—for reasons, at least, of self-interest, if not justice.
Is the location of the signal intensity weighted centroid a reliable measurement of fluid displacement within the disc?
Authors: Abdollah Vahid , Parent Eric C. , Battié Michele C. 
Published: June 2017

AbstractDegenerated discs have shorter T2-relaxation time and lower MR signal. The location of the signal-intensity-weighted-centroid reflects the water distribution within a region-of-interest (ROI). This study compared the reliability of the location of the signal-intensity-weighted-centroid to mean signal intensity and area measurements. L4-L5 and L5-S1 discs were measured on 43 mid-sagittal T2-weighted 3T MRI images in adults with back pain. One rater analysed images twice and another once, blinded to measurements. Discs were semi-automatically segmented into a whole disc, nucleus, anterior and posterior annulus. The coordinates of the signal-intensity-weighted-centroid for all regions demonstrated excellent intraclass-correlation-coefficients for intra- (0.99–1.00) and inter-rater reliability (0.97–1.00). The standard error of measurement for the Y-coordinates of the signal-intensity-weighted-centroid for all ROIs were 0 at both levels and 0 to 2.7 mm for X-coordinates. The mean signal intensity and area for the whole disc and nucleus presented excellent intra-rater reliability with intraclass-correlation-coefficients from 0.93 to 1.00, and 0.92 to 1.00 for inter-rater reliability. The mean signal intensity and area had lower reliability for annulus ROIs, with intra-rater intraclass-correlation-coefficient from 0.5 to 0.76 and inter-rater from 0.33 to 0.58. The location of the signal-intensity-weighted-centroid is a reliable biomarker for investigating the effects of disc interventions.
Prediction of human iron bioavailability using rapid c-ELISAs for human plasma hepcidin

Published: June 2017

Abstract

Background:
Hepcidin is the central systemic regulator of iron metabolism, but its quantification in biological fluids is challenging. Rapid, accurate and user-friendly methods are needed. Our aim was to assess the ability of hepcidin as measured by three different c-ELISA assays to predict iron bioavailability in humans.

Methods:
The three assays used were commercially available DRG and Peninsula assays and the c-ELISA method performed at Radboud University Medical Centre, Nijmegen, The Netherlands (Hepcidinanalysis.com), validated by comparative measurements with time-of-flight mass spectrometry. We analyzed plasma samples (n=37) selected to represent a broad range of hepcidin concentrations from a subgroup of healthy, iron-depleted women in a study assessing fractional absorption from iron supplements.

Results:
In single regressions, all three c-ELISA assays were predictors of fractional iron absorption: R2=0.363 (DRG), R2=0.281 (Peninsula) and R2=0.327 (Hepcidinanalysis.com). In multiple regressions, models including hepcidin measured with either DRG-, Peninsula or Hepcidinanalysis.com explained 55.7%, 44.5% and 52.5% of variance in fractional absorption, and hepcidin was a strong predictor of fractional absorption irrespective of the hepcidin assays used. However, we found significant differences in absolute values for hepcidin between different methods. Both the DRG assay’s (y=0.61x+0.87; R2=0.873) and the Peninsula assay’s measurements (y=1.88x+0.62; R2=0.770) were correlated with Hepcidinanalysis.com.

Conclusions:
The biological variability in plasma hepcidin, (inter-sample CV) was 5–10-fold higher for both the Peninsula and DRG assay than the analytical variably (inter-run within-sample CV) suggesting substantial discriminatory power to distinguish biological hepcidin variation. Between methods, prediction of iron bioavailability in generally healthy iron depleted subjects appears comparable.

Abstract

Introduction
Studies conducted in the recent past have demonstrated the role of inflammation, obesity and dysfunctional insulin signaling as contributing factors in the pathogenesis of acute coronary syndrome (ACS). However, pharmacological interventions targeting a single pathway have not proven useful in the long run. This indicates that a synergism occurs between the various risk factors and hence calls for a combinatorial approach. This study was planned to study the interplay, if any, between pregnancy associated plasma protein-A (PAPP-A), inflammation and adiposity in patients with ACS.

Materials and methods
The study was conducted in a tertiary care hospital in Delhi. The study population consisted of 128 subjects, divided into two groups. The control group consisted of 64 healthy subjects without ACS. Cases consisted of 64 subjects with angiographically proven ACS cases. PAPP-A and high sensitivity C-reactive protein (hs-CRP) were estimated by enzyme-linked immunosorbent assay (ELIZA) kits.

Results
The mean level of PAPP-A and hs-CRP were significantly higher in cases as compared to the controls. A positive correlation of PAPP-A was observed with hs-CRP, insulin, ApoB and Lp(a). The relative risk for ACS was 14.2 with a p value of <0.001 when all the three parameters – hs-CRP, PAPP-A and body mass index (BMI) were considered together. This was significantly higher when each risk factor was assessed standalone.

Conclusions
Our study results suggest a possible interplay between chronic inflammation, obesity and plaque instability among patients with ACS. This interaction can accelerate the process of plaque rupture in patients with increased BMI as compare to those patients with low/normal BMI.
Long-term dutasteride therapy in men with benign prostatic hyperplasia alters glucose and lipid profiles and increases severity of erectile dysfunction

Published: June 2017

AbstractBackgroundDutasteride has been successfully used in treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). However, dutasteride inhibits 5α-reductase type 1 and type 2 enzymes and may compromises glucocorticoids and androgen metabolism and alters metabolic function resulting in undesirable metabolic and sexual adverse side effects.AimThe aim of this study was to investigate the long-term adverse effects of dutasteride therapy in men with BPH on: i) blood glucose, ii) glycated hemoglobin (HbA1c), iii) low density lipoprotein-cholesterol (LDL-C); high density lipoprotein-cholesterol (HDL-C) and total cholesterol (TC), iv) testosterone (T), v) liver alanine and aspartate aminotransferases (ALT and AST) and vi) erectile dysfunction (ED).MethodsA retrospective registry study, with a cohort of 230 men aged between 47 and 68 years (mean 57.78 ± 4.81) were treated with dutasteride (0.5 mg/day) for LUTS, secondary to BPH. A second cohort of 230 men aged between 52 and 72 years (mean 62.62 ± 4.65) were treated with tamsulosin (0.4 mg). All men were followed up for 36–42 months. At intervals of 3–6 months, and at each visit, plasma glucose, HbA1c, TC, LDL-cholesterol, T levels and liver alanine amino transferase (ALT) and aspartate aminotransferase (AST) were determined. Further patient assessment was made by the International Index of Erectile Function (IIEF-EF) questionnaire, the Aging Male Symptom (AMS) and International Prostate Symptom Scores (IPSS).ResultsLong-term treatment with dutasteride therapy is associated with significant improvements in LUTS, as assessed by reduction in prostate volume, IPSS and prostate specific antigen (PSA). Long-term dutasteride therapy, however, resulted in increased blood glucose, HbA1c, TC and LDL levels, ALT and AST activities, AMS Score and reduced T levels and worsened ED as assessed by the IIEF-EF scores. No worsening of ED, glucose, HbA1c, ALT, AST, AMS were observed in men treated with tamsulosin. Most importantly, long-term dutasteride therapy resulted in reduction in total T levels, contributing to a state of hypogonadism.ConclusionOur findings suggest that long-term dutasteride therapy produces worsening of ED, reduced T levels and increased glucose, HbA1cand alters lipid profiles, suggesting induced imbalance in metabolic function. We strongly recommend that physicians discuss with their patients these potential serious adverse effects of long-term dutasteride therapy prior to instituting this form of treatment.
West German Borderland Aid and European State Aid Control
Authors: Eckert Astrid M. 
Published: June 2017

Abstract
This article focuses on one of the most persistent regional aid programmes in West German history, the so-called “zonal borderland aid” (Zonenrandförderung). The programme supported regions along the 1,393-kilometer long inter-German border that divided West and East Germany during the Cold War. The article seeks to explain the increasingly fraught relationship between borderland aid and European state aid control in the 1970s and 1980s. The intervention of the Directorate for Competition (DG IV) against borderland aid begs an explanation since the Treaty of Rome (1957) had granted a specific exemption for aid to these regions from the competition policies of the Common Market. The article makes the general case that regional state aid is a key component of structural policy alongside sectoral aid. It argues that interest politics prevented a sober needs assessment of the West German border regions, turning Zonenrandförderung into funding by habit, not by need. This left the European Commission as the only institution that could mount a credible challenge to an ossified sense of entitlement in the affected regions.
A Capabilities-Based Framework for Disaster Response Exercise Design and Evaluation: Findings from Oil Spill Response Exercises
Authors: Greenberg Brandon , Voevodsky Paule , Gralla Erica 
Published: June 2017

Abstract
The responder community must be ready to respond quickly and effectively in the event of a disaster. In order to maintain readiness, many disaster response communities exercise their response capabilities on a regular basis. The critical challenge is to design, conduct, and evaluate exercises in a manner that effectively tests responders’ readiness and generates lessons that can improve readiness. This paper describes a framework to enable assessment of response readiness through evaluation of critical capabilities in exercises. It was developed for oil spill response based on the observation and analysis of four response exercises. The framework (1) identifies critical capabilities that lead to readiness for spill response, and maps them to (2) exercise design components that test each capability and (3) evaluation measures to evaluate each capability within an exercise. The framework enables continuous improvement by linking the evaluation of exercises to the critical capabilities required of an oil spill response organization; by evaluating the performance of specific capabilities, areas for improvement are clearly identified and can be re-tested in a future exercise. While the findings are necessarily specific to oil spill response, the principles apply to any disaster response context.
