Going With Your Gut: The (In)accuracy of Forecast Revisions in a Football Score Prediction Game

This paper studies 150 individuals who each chose to forecast the outcome of 380 fixed events, namely all football matches during the 2017/18 season of the English Premier League. The focus is on whether revisions to these forecasts before the matches began improved the likelihood of predicting correct scorelines and results. Against what theory might expect, we show how these revisions tended towards significantly worse forecasting performance, suggesting that individuals should have stuck with their initial judgements, or their ‘gut instincts’. This result is robust to both differences in the average forecasting ability of individuals and the predictability of matches. We find evidence this is because revisions to the forecast number of goals scored in football matches are generally excessive, especially when these forecasts were increased rather than decreased.
The First Constraint from SDSS Galaxy–Galaxy Weak Lensing Measurements on Interacting Dark Energy Models

We combine constraints from linear and nonlinear scales, for the first time, to study the interaction between dark matter (DM) and dark energy (DE). We devise a novel N-body simulation pipeline for cosmological models beyond ΛCDM. This pipeline is fully self-consistent and opens a new window to study the nonlinear structure formation in general phenomenological interacting DE models. By comparing our simulation results with the SDSS galaxy–galaxy weak lensing measurements, we are able to constrain the strength of interaction between DE and DM. Compared with the previous studies using linear examinations, we point to plausible improvements on the constraints of interaction strength by using small-scale information from weak lensing. This improvement is mostly due to the sensitivity of weak lensing measurements on nonlinear structure formation at low redshift. With this new pipeline, it is possible to look for smoking gun signatures of DM–DE interaction.

LABOUR ADJUSTMENT COSTS : ESTIMATION OF A DYNAMIC CHOICE MODEL USING PANEL DATA FOR GREEK MANUFACTURING FIRMS

In this paper we estimate a dynamic structural model of employment at the firm level. Our dataset consists of a balanced panel of 2790 Greek manufacturing firms. The empirical evidence of this dataset stresses three important stylized facts: (a) there are periods in which firms decide not to change their labour input and stay inactive, (b) there are periods of large employment changes (lumpy nature of labour adjustment) and (c) the commonality is employment spikes to be followed by smooth and low employment growth periods. Following Cooper and Haltiwanger (2006) we consider a dynamic discrete choice model of a general specification of adjustment costs including convex, non-convex and “disruption of production” components. We use a method of simulated moments procedure to estimate the structural parameters. Our goal is to investigate the nature of the labour adjustment process at the firm level for Greek data.

BIOMEDICAL AND COOLING APPLICATIONS OF MICRO FLOWS MUHSİNCAN ŞEŞEN Submitted to the Graduate School of Engineering and Natural Sciences in partial fulfillment of the requirements for the degree of Master of Science SABANCI

Micro flows find applications in a variety of topics covering biomedical, cooling, electronics and MEMS (micro-electro-mechanical-systems) applications. In this work, the destructive effects of hydrodynamic cavitation for biomedical treatment, heat transfer enhancement with nanostructures and nanofluids for small scale cooling applications were investigated. The research performed in this study includes results from bubbly cavitation experiments and findings showing the destructive effects of bubbly cavitating flow on selected solid specimens, live cells and proteins. Our results showed that cavitation could induce damage both on chalk pieces (and possibly kidney stones) and leukemia/lymphoma cells while the secondary structure content, the hydrodynamic diameter and enzymatic activity of lysozyme were unaffected by cavitation. For the purpose of making compact and efficient heat exchangers, heat transfer enhancement with nanostructures could be considered as a futuristic candidate. Thus, heat transfer characteristics of nanostructured plates, on which an array of vertical and tilted copper nanorods with an average diameter ranging from 100 to 150 nm and length 500 to 600 nm are integrated to a planar copper thin film coated silicon wafer surface, were compared to planar copper thin film coated silicon wafer surfaces via three different heat transfer techniques (pool boiling, forced convection and jet impingement). Three different heat sinks were developed for this purpose. Surface temperatures were measured and heat transfer coefficients were calculated for the designed heat sinks and an average of 22% single-phase heat transfer enhancement was realized with the nanostructured plates.
Can anti-Müllerian hormone be predictive of spontaneous onset of pregnancy in women with unexplained infertility?

The objective of the study was to assess anti-Müllerian hormone's (AMH) role in predicting spontaneous onset of pregnancy. This observational cohort study included 83 women with unexplained infertility and normal or low ovarian reserve. Serum AMH, FSH, LH, 17β-oestradiol, inhibin B levels were measured and the number of early antral follicles (2–9 mm) was evaluated on days 2–5 of the cycle. Spearman's correlation was used for comparison of strength of correlation. The diagnostic power of AMH in predicting spontaneous pregnancy was evaluated by receiver operating characteristic (ROC) curves. Markers of ovarian reserve in pregnant women and women without pregnancy were similar. In the entire study population, any markers (AMH, FSH, AFC, age), correlated with each other, but no marker was correlated with pregnancy. The area under the ROC curve for AMH reached a value of 0.385 ± 0.07 (0.25–0.52, 95% confidence interval, CI); for FSH 0.415 ± 0.08 (0.25–0.58, 95% CI); for AFC 0.418 ± 0.08 (0.26–0.57, 95% CI), for age 0.496 ± 0.08 (0.34–0.65, 95% CI). The study did not find a predictive role for AMH in predicting spontaneous onset of pregnancy. Even when AMH levels are very low, a spontaneous pregnancy may still occur.
EFFECTS OF PLANT GROWTH REGULATORS ON SEED GERMINATION AND CALLUS INDUCTION OF HYLOCEREUS COSTARICENSIS

Dragon fruit (Hylocereus costaricensis) belongs to the family Cactaceae and are climbing vines which have received worldwide attention in recent years. However, there are still lack of information on the protocols for the establishment of In vitro culture system. In the present study, seed germination percentage were determined by culturing seeds on semi-solid Murashige and Skoog medium (MS) supplemented with 1 ppm 6-Benzylaminopurine (BAP) together with either 0, 0.5 or 0.8 ppm of Indole-3-butyric acid (IBA). Germination percentage was the highest by using plant growth regulators (PGRs) combination of 1 ppm BAP and 0 ppm IBA (93.33%). Subsequently, the cotyledons from seedlings of the germinated seeds were used for subsequent callus induction. Small pieces of cotyledons were excised and cultured on MS medium fortified with 0.45, 0.9, 1.8, 2.7, 3.6, and 4.5 ppm of 2,4-Dichlorophenoxyacetic acid (2,4-D) together with either 0, 0.9 or 1.8 ppm of BAP. Callus induction percentage was highest using the plant growth regulators (PGRs) combination of 3.6 ppm 2,4-D and 1.8 ppm BAP (75%). Hence, 3.6 ppm of 2,4-D and 1.8 ppm BAP was the best combination for callus induction of Hylocereus costaricensis.
Operational Excellence as the Main Customer Value: Information Technology Vendors' Perspective

Abstract Background: Information technology (IT) requires substantial investments from enterprises to build competitive capabilities. IT products are supposed to provide value to customers and to increase the competitiveness of enterprises. Vendors of IT products should take the competitive strategy and value creation for enterprise buyers into account. Objectives: This article takes the perspective of IT vendors (ITVs) and attempts to answer the research questions “What types of customer value do ITVs consider? ” and “Do ITVs consider the competitiveness of enterprises? ” Methods/Approach: This research investigates descriptions from ITVs and analyzes patterns and correlations of coded content. The annual reports of 32 global market-leading ITVs were examined through direct content analysis. Results: Half of the annual reports mention the competitiveness of enterprise buyers; 84% of the samples relate to customer-value disciplines. Moderate positive and monotonic relationships were detected between customer value disciplines. Conclusions: ITVs consider the competitiveness of buyers and noticeably regard customer value disciplines, mainly operational excellence, that in turn refers to process efficiency and cost-effectiveness.
Evaluating the influence of meteorite impact events on global potassium feldspar availability to the atmosphere since 600 Ma

Potassium feldspar present in global mineral aerosol (<5%) plays a disproportionate role in modulating the microphysics of mixed-phase cloud. Via exceptional ice nucleation properties, it is capable of changing cloud properties and behaviour. Here we identify times of substantial and abrupt change in the global availability of potassium feldspar since 600 Ma. Normally, weathering and vegetation cover contribute to low availability, with clay dominating mineral aerosol. Periods of maximum availability are reasoned to follow the emplacement and remobilization of ejecta blankets from major meteorite impact events, before returning to background after some hundreds to thousands of years. We review the 44 largest confirmed craters and evaluate the potassium feldspar content of their target rocks, which range from c. 0 to >30%. By combining crater size and tectonic reconstructions, we are able to provide a quantitative and self-consistent assessment of changes to global potassium feldspar availability. Considerable differences in potassium feldspar availability following meteorite impact events are revealed. Different impact events generated dust containing different amounts of potassium feldspar. Differing levels of influence upon climate are hypothesized, and should now be tested by looking at stratigraphic records of these events to reveal the sensitivity of climate to different dust mineralogy. Supplementary material: Figures showing palaeolatitude determinations using various methods and reconstruction models, and estimates of alkali feldspar abundance and distribution across contemporary continental landmasses for meteorite impact events are available at: https://doi.org/10.6084/m9.figshare. c.4253312
Conceptual study of a Compton polarimeter for the upgrade of the SuperKEKB collider with a polarized electron beam

The physics scope of the Belle II experiment currently acquiring data at the SuperKEKB collider will expand with a polarized electron beam upgrade, as recently proposed. Among the required elements for this upgrade, a real time diagnosis of the polarization is necessary to ensure it is large for all bunches in the accelerator during its regular operation. This will be realized by inserting a Compton polarimeter in the accelerator. Its conceptual design is described and no show-stopper for its integration has been identified. An estimation of the sensitivity of the polarimeter is made by means of toy Monte-Carlo studies. The proposed design accounts for the constraint to preserve the performance of the SuperKEKB accelerator and to cope with the short time separation of successive bunches. We show that the polarimeter will measure for each bunch the polarization within five minutes with a statistical precision below 1% and systematic uncertainties below 0.5%. It has the capability of providing this information online on a similar timescale. This work paves the way towards future implementation of real-time Compton polarimetry in several future projects.
Machine-learning Inferences of the Interior Structure of Rocky Exoplanets from Bulk Observational Constraints

Characterizing the interiors of rocky exoplanets is important to understand planetary populations and further investigate planetary habitability. New observable constraints and inference techniques have been explored for this purpose. In this work, we design and train mixture density networks (MDNs) to predict the interior properties of rocky exoplanets with large compositional diversity. In addition to measurements of mass and radius, bulk refractory elemental abundance ratios and the static Love number k 2 are used to constrain the interior of rocky exoplanets. It is found that the MDNs are able to infer the interior properties of rocky exoplanets from the available measurements of exoplanets. Compared with powerful inversion methods based on Bayesian inference, the trained MDNs provide a more rapid characterization of planetary interiors for each individual planet. The MDN model offers a convenient and practical tool for probabilistic inferences of planetary interiors.
Effect Of Speaking Rate Modification On Articulation And Pause Characteristics In Individuals With Parkinsonâ€™s Disease

The purpose of this study was to examine effect of rate modification on parameters of rate in individuals with idiopathic Parkinsonâ€™s disease. Fifteen native Marathi speakers within the age range of 50 â€“ 80 years with Idiopathic Parkinsonâ€™s Disease (PD) and fifteen healthy controls (HC) participated in the study. The participants read a Marathi passage at three rate conditions; habitual, fast and slow. Speaking rate, articulation rate, pause duration, and pause frequency was extracted for the two speaker groups using PRAAT software. Findings of the study show that for PD speakers, the average speaking rate, & articulation rate was reduced but pause duration and pause frequency was increased as compared to HC speakers. The PD speakers altered their rate and pause characteristics in a similar way as done by HC speakers to achieve speaking rate changes, however, the extent of change was lesser for PD speakers.
Autonomy-Supportive Teachers: How They Teach and Motivate Students

The authors examined motivating style in terms of a teacher's disposition to control students or support their autonomy. In Study 1, 4 independent samples of preservice teachers completed the Problems in Schools (PS) questionnaire so the authors could critically evaluate the instrument to assess motivating style as an individual difference characteristic. In Study 2, preservice teachers taught a 10-min instructional episode as raters judged their language and style. In Study 3, elementary and high school teachers self-reported a recent attempt to teach and motivate one of their students. Compared with their controlling counterparts, autonomy-supportive teachers showed a distinctive motivating style as measured by their conversational behaviors, interpersonal style, and attempts to support students' intrinsic motivational and internalization processes.
The Output Cost of Latin America’s Infrastructure Gap

Latin American has lost substantial ground relative to other developing and developed regions in terms of the quality and quantity of infrastructure over the last two decades. For instance, Latin America’s infrastructure gap in infrastructure growth relative to that of the seven successful economies of East Asia grew by 40-50 percent for road length, 50-60 percent for telecommunications, and as much as 90-100 percent in terms of power generation capacity over the 1980-97 period. The consequences of this loss of ground or growth and welfare in the region are a matter of concern. Lack of adequate infrastructure services results in lower productivity and higher production costs for private producers. Poor road and telecommunication networks raise transport and, more generally, logistic costs, which have been shown in comparative studies to exceed the international norm by wide margins (Guasch, 2001). The reduced profitability in turn discourages private investment. Through all these channels, the result is lower output growth. As with infrastructure, Latin America’s loss of ground was particularly marked in the 1980s. We find evidence of a strong empirical association between output and infrastructure although this need not reflect causation from infrastructure services to aggregate output. The present paper wants to determine the role of Latin America’s growing infrastructure gap in the widening of the output gap. We devote our efforts in this paper to answer this question.
Thermodynamic properties of Mercury based cuprate due to Cooper pair-electron interaction

Interaction between electrons at the critical temperature that culminates into formation of Cooper pair holds the key in explaining cuprates high temperature superconductivity. We study the effects of the number of copper oxide planes on thermodynamic properties of Mercury based high temperature superconductivity due to an interaction between cooper pair and electrons. We noted that the energy of interaction at the critical temperature was seen to increase with increase in the number of copper oxide planes. The specific heat, Sommerfeld coefficient and the entropy per unit mass, decreased with an increase in the number of copper oxide planes. The peak Sommerfeld coefficient temperature was noted to be approximately 0.66 times critical temperature in all considered cases of mercury based cuprates.
Parties, Coalitions, and the Internal Organization of Legislatures

We present a theory of parties-in-legislatures that can generate partisan policy outcomes despite the absence of any party-imposed voting discipline. Legislators choose all procedures and policies through majority-rule bargaining and cannot commit to vote against their preferences on either. Yet, off-median policy bias occurs in equilibrium because a majority of legislators with correlated preferences has policy-driven incentives to adopt partisan agenda-setting rules—as a consequence, bills reach the floor disproportionately from one side of the ideological spectrum. The model recovers, as special cases, the claims of both partisan and nonpartisan theories in the ongoing debate over the nature of party influence in the U.S. Congress. We show that (1) party influence increases in polarization, and (2) the legislative median controls policy making only when there are no bargaining frictions and no polarization. We discuss the implications of our findings for the theoretical and empirical study of legislatures.
Non Neutral Plasmas in the CNT Stellarator

, This work was supported by the United States DOE Grant DE-FG02-02ER54690, the NSF-DOE Partnership in Basic Plasma Science, Grant NSF-PHY-04-49813, and the DOE Fusion Energy Sciences Postdoctoral Research Program. z email: qrm1@columbia.edu Introduction: The study of non-neutral plasmas confined on magnetic surfaces has only begun recently. Theoretical predictions show that the equilibrium, stability, and transport of these plasmas are fundamentally different from non-neutral plasmas in Penning-Malmberg traps or pure toroidal traps. These plasmas are stable to many oscillations [2]. The large electric fields cause an ExB drift of particles within surfaces, countering cross-surface drifts. This is predicted to lead to excellent confinement [3]. The Columbia Non-neutral Torus (CNT) is an experiment designed to study non-neutral plasmas confined on magnetic surfaces [4]. This stellarator configuration is created with just four circular coils (see Fig. 1). Electron plasmas are then created in steady-state by emitting from a biased tungsten filament inside the plasma.

Included are the vacuum vessel (cut in half), the two outer poloidal field coils, the two inner interlocking coils, and the rendering of the last closed magnetic flux surface.
Iheringia Molecular and morphological approaches for species delimitation and hybridization investigations of two Cichla species

The hybridization is a widely-discussed issue in several studies with fi sh species. For some authors, hybridization may be related with diversifi cation and speciation of several groups, or also with the extinction of populations or species. Diffi culties to diff erentiate species and hybrids may be a problem to correctly apply a management of wild species, because hybrid lineages, especially the advanced ones, may resemble the parental species. The genus Cichla Bloch & Schneider, 1801 constitutes an interesting experimental model, considering that hybridization and taxonomic uncertainties hinder a correct identifi cation. Considering these problems, in this study, we developed genetic methodologies and applied meristic and morphometric approaches in wild samples in order to identify species and for test a possible hybridization between Cichla kelberi Kullander & Ferreira, 2006 and Cichla piquiti Kullander & Ferreira, 2006. For this, C. kelberi, C. piquiti and potential hybrid (carijó) individuals were collected in Paraná and Tietê rivers (SP, Brazil). For meristic and morphometric methods, the individuals were analyzed using the statistical software Pcord 5:31, while for molecular methods, primers for PCR-multiplex were designed and enzyme for PCR-RFLP were selected, under the species-specifi c nucleotide. All results indicated that the carijó is not an interspecifi c hybrid, because it presented identical genetic pattern and morphology closed to C. piquiti. Thus, we propose that carijó is a C. piquiti morphotype. In addition, this study promotes a new molecular tool that could be used in future research, monitoring and management programs of the genus Cichla.
