Changes in ENSO teleconnections under greenhouse-gas forcing : implications for fisheries off the western coast of South America

Author(s): Passalacqua Walter, Gino Angelo | Abstract: The Humboldt Current Ecosystem (HCE) is one of the most productive systems in the world. The interannual and interdecadal ocean-atmospheric variations in the Southeast Pacific (SEP) have recognized impacts on the HCE fisheries, especially during El Nino - Southern Oscillation (ENSO) events. To understand how anthropogenic climate change might affect HCE fisheries, the changes in teleconnections between the Peru/Chile coasts and the Pacific Ocean under these circumstances were investigated. Sea-surface temperature (SST) from the Parallel Climate Model (PCM) under the IPCC pre-industrial, 20th century and two future GHG scenarios were obtained to study these effects, by creating indices to identify the teleconnections. We use EOFs to identify the warming trend spatial patterns, which are then removed to form detrended SST anomalies (SSTA) in order to examine ENSO statistics on a changing background state. We find an increase in the amplitude of the interannual SSTA in the Nino 3.4 region and along the coast of the SEP in the PCM IPCC runs, corroborated with observations from the HADISST data set. Atmospherically forced ENSO teleconnections broaden latitudinally and expand poleward under the influence of the trends in the background ocean-atmosphere state, independently from the IPCC scenario and the period of analysis. Under GHG forcing, there is a significant increase in correlations between the Equatorial Pacific and the SEP coast, especially in a region off Central / South Chile, indicating a poleward expansion of an "ENSO-like" pattern. Based on their historical responses to environmental variations, the possible effects of global warming on the HCE's small pelagics fisheries are discussed.
When Kerry Met Sally : Politics and Perceptions in the Demand for Movies ∗

On election days many of us see a colorful map of the U.S. where each tiny county has a color on the continuum between red and blue. So far we have not used such data to improve the effectiveness of marketing models. In this study, we show that we should. We demonstrate the usefulness of political data via an interesting application—the demand for movies. Using boxoffice data from 25 counties in the U.S. Midwest (21 quarters between 2000 and 2005) we show that by including political data one can improve out-of-sample predictions significantly. Specifically, we estimate the improvement in forecasts due to the addition of political data to be around $43 million per year for the entire U.S. theatrical market. Furthermore, when it comes to movies we depart from previous work in another way. While previous studies have relied on pre-determined movie genres, we estimate perceived movie attributes in a latent space and formulate viewers’ tastes as ideal points. Using perceived attributes improves the out-of-sample predictions even further (by around $93 million per year). Furthermore, the latent dimensions that we identify are not only effective in improving predictions, they are also quite insightful about the nature of movies. ∗Our thanks go to Preyas Desai, Ron Goettler, Joel Huber, Wagner Kamakura, Carl Mela, Rick Staelin, and Andrew Sweeting who were kind enough to share some of their expertise. We are especially grateful to Bob Markley for his essential role in obtaining data for this project. †Doctoral candidate, Fuqua School of Business, Duke University, Durham, N.C. , U.S.A. 27708 E-mail: jason.roos@duke.edu ‡Faculty of Management, Tel Aviv University, Tel Aviv, Israel 69978 E-mail: rroonn@post.tau. ac.il; and Fuqua School of Business, Duke University, Durham, N.C. , U.S.A. 27708 E-mail: shachar@duke.edu

: The purpose of this study is to examine the fears of children who are 6-10 years old via drawings. In this study, phenomenology research design which is among qualitative research methods was used. The study group of the study consisted of 314 children aged between 6 and 10 years in three primary schools in Kirsehir city center in 2017-2018 academic year. The data obtained from the participants were analyzed by using the content analysis method. As a result of the research, the drawings were collected under 6 categories according to their similar characteristics . When the drawings obtained from the children were classified, it was seen that the most fear is related to the category of animals, while the least fear is related to the drawings of the category of fears related to medical. In addition, children preferred to use black, red, blue, yellow and green colors in their fear themed drawings.
Geological Survey of Canada Radiocarbon Dates XI

During the past year, 1969-1970, both the 2-L (Dyck and Fyles, 1962) and 5-L (Dyck et al., 1965) counters were routinely operated. A 1-L counter was finally constructed with acceptable characteristics (see description below) and was operated in July in place of the 5-L counter. The 2-L counter was operated exclusively at 2 atm. The 5-L counter was operated at 1 atm, except for October and November, 1969, when it was operated at 4 atm. The 1-L counter was operated at 1 atm.
THE ACCRUAL ANOMALY : RISK OR MISPRICING ?

We document considerable return comovement associated with accruals after controlling for other common factors. An accrual-based factor-mimicking portfolio has a Sharpe ratio of 0.15, higher than that of the market factor or the HML factor of Fama and French (1993). In time series regressions, a model that includes the Fama-French factors and the additional accrual factor captures the accrual anomaly in average returns. However, further time series and cross-sectional tests indicate that it is the accrual characteristic rather than the accrual factor loading that predicts returns. These findings favor a behavioral explanation for the accrual anomaly.
Antibody-Conjugated Gold Nanoparticle-Based Immunosensor for Ultra-Sensitive Detection of Troponin-T

The technology presented in this study demonstrates the feasibility of integrating nanostructures onto the surface of an electrical platform to achieve enhanced detection of the cardiac biomarker, troponin-T. A polymer microcontact printing technique was modified using printed circuit boards as molds for the application of gold nanoparticles onto microelectrode-patterned glass substrates. The microelectrodes were designed to support electrical impedance spectroscopy measurements and fabricated using standard photolithography methods. Capture antibodies specific to troponin-T were functionalized onto the surface of gold nanoparticles by using a thiol-based cross-linking molecule. The antibody-conjugated gold nanoparticles were stamped onto the electrodes using a matching pattern imprinted onto an elastomeric mold. As a control to validate the efficacy of the nanotextured surface on the glass substrate, an electroplated printed circuit board was also used. The incorporation of gold nanoparticles showed significant amplification of the electro-ionic signals generated through binding of the antigen to its capture antibody. Enhanced sensitivity was demonstrated through detection of the target biomarker in the femtogram per milliliter range in buffer solution and biological media. In the absence of gold nanoparticles, the sensor demonstrated detection of troponin-T at higher concentration points. This study illustrates a robust method for developing a more sensitive, label-free biosensor.
) Nonverbal behaviour accompanying challenge and threat states under pressure. Psychology of Sport and Exercise, 39. pp. 90-94

Objectives: This study examined if challenge and threat states predicted nonverbal behavior during a pressurized soccer penalty task. Design: A predictive design was employed. Method: Forty-two participants ( M age = 24 years, SD = 7) completed the task. Before the task, challenge and threat states were assessed via demand resource evaluations and cardiovascular reactivity. During the task, nonverbal behavior was recorded, and later used to rate participants on six scales: (1) submissive–dominant, (2) unconfident–confident, (3) on edge–composed, (4) unfocused–focused, (5) threatened–challenged, and (6) inaccurate–accurate. Results: Participants who evaluated the task as a challenge (coping resources exceed task demands) were deemed more dominant, confident, composed, challenged, and competent from their nonverbal behavior than those who evaluated it as a threat (task demands exceed coping resources). Cardiovascular reactivity did not predict nonverbal behavior. Conclusions: Athletes’ challenge and threat evaluations might be associated with nonverbal behavior under high-pressure.
The odyssey of “ alternative firms ” : new organizational propositions from a case-study

The odyssey of " alternative firms " : new organizational propositions from a case-study Abstract Lately, " conventional " firms have been roughly criticized for both the legitimacy of shareholder value and the production of negative externalities that affect society. In the crisis context, " alternative " firms are often presented as candidates to design renewed organizations. However, there is a high risk of arousing as much initial enthusiasm as following disillusion. In this paper, we address the issue of the organizational dynamics of such corporate projects over time. After a (brief) historical overview of alternative firms, we discuss the limitations of dominant approach which sustains the " degeneration thesis. " We then elaborate a new analytical framework that raises the issues of alternative firms in another fashion to go beyond traditional tradeoffs between democratic functioning and financial performance. The framework is then used to longitudinally analyze the story of Garden Concept, an alternative firm operating in artistic gardening, over seven years. Our findings show how the building of dynamic relations between members, common purpose and organizational devices are at the heart of the alternative firm's project. So doing, we explore a larger redefinition of these three elements and depart from a close association of " alternative " project to strict democracy. Contributions to " alternative firms " as well as research perspectives on professional and artistic organizations are eventually considered.
THE INFLUENCE OF LEARNER BEHAVIOUR ON BEGINNER TEACHERS’ PERCEPTIONS OF THEIR OWN CREDIBILITY

Traditionally, teacher credibility has been influenced by how others perceive them. However, exploring teachers’ own perceptions of their credibility through the observation of learner behaviour may prove to be meaningful to teacher credibility. The aim of this study was to explore Intermediate Phase beginner teachers’ perceptions of their own credibility based on displayed learner behaviour in their classrooms. This qualitative study was presented through a case study research design. Eight Intermediate Phase beginner teachers were purposively selected. The data collection techniques used were interviews and observations. Semi-structured interviews and a researcher journal were used as data collection instruments. The data were analysed using inductive thematic data analysis. The conceptual framing of this study was underpinned by a modified theoretical model developed by McCroskey, Valencic and Richmond (2004). The findings showed that teachers’ perceptions of their own credibility were fluid as they engaged with various learners’ behaviour, which was used as a form of feedback during lessons and this feedback impacted teachers’ reactions and decisions to classroom situations. Ultimately, teachers’ perceptions of their own credibility focused on their immediacy, trustworthiness, competence and dynamism displayed in their practices. learner discipline, learner interest and learner motivation.
La transhumance Transfrontalière en Afrique de l’Ouest

The cross-border transhumance in Western Africa In our days, it is indisputable that the transhumance in cross-border Sahel countries is in the core of all the analyzes focused on the cross-border cooperation and local development in Africa. This explains without doubt all the complexity which envelope the hulling of such a topic in view of the vastness of its scope of application. In fact, dealing with the cross-border transhumance is not an easy thing, on the contrary, it is a delicate task which requires an approach very methodical, and considerable knowledge of specific thematic to cortex pastoral legal in Africa. Therefore it would be wise to ask the question of what are the existing legal instruments on the cross-border transhumance in West Africa? The African Union is protecting the rights to pastoral communities? What are the devices at the same time State but also associative put in place by the countries of West Africa in order to better regulate the cross-border transhumance? My analysis will focus therefore on the contours of the growing recognition of the right of pastoral communities by regional forums African (I). I am also interested in the analysis of different legal instruments guaranteeing the vitality of transhumants at local level (II). Keywords: Transhumance, West Africa, cross-border Cooperation.
The development and use of environmental health indicators for epidemiology and policy applications: a geographical analysis

This thesis examines the development and use of environmental health indicators for epidemiology, risk assessment and policy applications from a geographical perspective. Although indicators have traditionally been used to examine temporal trends, the development of environmental health indicators (EHIs) may enable comparisons to be made between areas with contrasting environmental health conditions, support efforts to highlight ‘hot spots’ and facilitate the analysis of spatial patterns in environmental health conditions and health risk. The use of environmental health indicators is relatively new and little research has been conducted in this area. In the light of this, this thesis examines EHIs in the context of contemporary developments in environmental indicators, health-related and quality of life indicators, and indicators of sustainable development. Essential characteristics and requirements for EHIs are identified and the main areas of application are discussed. In the second part of the thesis, the development and use of Effis for evaluating exposure to traffic-related air pollution is examined, using GIS techniques. Potential indicators of exposure are identified and these are applied at a range of spatial scales, along with a number of additional measures. The results of this exercise show that although exposure to traffic-related air pollution is both difficult and costly to evaluate, proxy measures may be used. Pollutant concentrations, for example are frequently used to assess exposure, yet the lack of suitable data may also frequently preclude their use. Whilst other, cruder measures may be used, the relationship between these indicators, measured concentration and exposure is often uncertain. Consequently, EHIs for exposure to traffic-related air pollution may not provide a reliable indication of exposure and health risk. Their use in this area should therefore be undertaken with great caution and attempts made to validate specific measures prior to their use. At the same time, however, coarser ‘upstream’ indicators may provide relevant information in a policy context. For use in highlighting areas of concern, raising awareness about environmental health issues and encouraging policies which aim to improve environmental health conditions, ease of data collection and relation to policy may be more important than relation to specific health effects
Programming Our Lives: Television and American Identity

In this timely examination of television and American identity, Cummins and Gordon take readers on an informed walk through the changes that TV has already wrought-and those still likely to confront us. Commercial television in America is less than 60 years old, yet it has had an enormous impact on what we like, what we do, what we know, and how we think. A family transplanted from the 1940s to the present day would certainly be stunned by a fundamentally different world: instead of gathering in the living room for a shared evening of radio, they would be scattered around the house to indulge their individual interests on one of a hundred cable channels; instead of a society with rigid racial and ethnic divisions, they would see people of different ethnicities in passionate embraces; and certainly they would see very different sets of values reflected across the board. They would, in short, find themselves in an unrecognizable America, one both reflected in and shaped by television, a medium that has been shown to have an unprecedented influence on our lives both for better and for worse. By focusing on the development of television within the cultural context that surrounds it, and drawing on such phenomena as quiz shows, comedy hours, the Kennedy assassination, the Olympics, sitcoms, presidential ads, political debates, MTV, embedded journalism, and reality TV, the authors reveal television's impact on essential characteristics of American life. They cover topics as diverse as politics, crime, medicine, sports, our perceptions, our values, our assumptions about privacy, and our unquenchable need for more things. In addition, they consider the future of the medium in the light of the proliferation of programming options, the prevalence of cameras and receivers in our lives, the growing links between TV and computers, and the crossed boundaries of television throughout the world.
Measurement and validation of a three-factor hierarchical 3 model of competitive anxiety

Objectives : A novel analytical framework was used to re-examine and extend Cheng, Hardy 2 and Markland’s (2009) hierarchical model of anxiety. The modified model was characterized 3 by six first order constructs, with worry, private self-focus and public self-focus representing 4 cognitive anxiety, somatic tension and autonomous hyperactivity representing physiological 5 anxiety and perceived control representing the regulatory dimension. It was hypothesized that 6 these six first order constructs were formative indicators of the second order factors and this 7 hypothesis was tested using Partial Least Squares analysis. Factor validity of the original 8 hierarchical model proposed by Cheng et al. was investigated. Subsequently, items were 9 refined, the hierarchical model extended, and factor and predictive validity investigated further. 10 Method : Prospective data was collected from three samples (N= 174, 516, 43), and a series of 11 factor analyses were conducted including Confirmatory Factor Analysis and Partial Least 12 Squares modeling. Multivariate analysis examined the predictive validity of the model using a 13 performance measure as the dependent variable. 14 Results : The original model revealed a poor fit, with poor item loadings and discriminant 15 validity. Subsequent analysis established a refined 25 item measure, which produced support 16 for a fully differentiated hierarchical model of competitive anxiety. MANOVA revealed a 17 significant effect for the control factor, with those achieving superior performance reporting 18 significantly higher levels of perceived control. 19 Conclusions : A fully differentiated hierarchical model was supported, which crucially depicts 20 the first order factors of competitive anxiety that form the three second order dimensions. This 21 provides a model that is a better fit with theory and provides a more refined diagnosis tool for 22 applied sport psychologists.
Assessing Performance and Clinical Usefulness in Prediction Models With Survival Outcomes: Practical Guidance for Cox Proportional Hazards Models

Risk prediction models need thorough validation to assess their performance. Validation of models for survival outcomes poses challenges due to the censoring of observations and the varying time horizon at which predictions can be made. This article describes measures to evaluate predictions and the potential improvement in decision making from survival models based on Cox proportional hazards regression. As a motivating case study, the authors consider the prediction of the composite outcome of recurrence or death (the "event") in patients with breast cancer after surgery. They developed a simple Cox regression model with 3 predictors, as in the Nottingham Prognostic Index, in 2982 women (1275 events over 5 years of follow-up) and externally validated this model in 686 women (285 events over 5 years). Improvement in performance was assessed after the addition of progesterone receptor as a prognostic biomarker. The model predictions can be evaluated across the full range of observed follow-up times or for the event occurring by the end of a fixed time horizon of interest. The authors first discuss recommended statistical measures that evaluate model performance in terms of discrimination, calibration, or overall performance. Further, they evaluate the potential clinical utility of the model to support clinical decision making according to a net benefit measure. They provide SAS and R code to illustrate internal and external validation. The authors recommend the proposed set of performance measures for transparent reporting of the validity of predictions from survival models.
Intangible capital, corporate valuation and asset pricing

Recent studies have found unmeasured intangible capital to be large and important. In this paper we observe that by nature intangible capital is also very different from physical capital. We find it plausible to argue that the accumulation process for intangible capital differs significantly from the process by which physical capital accumulates. We study the implications of this hypothesis for rational firm valuation and asset pricing using a two-sector general equilibrium model. Our main finding is that the properties of firm valuation and stock prices are very dependent on the assumed accumulation process for intangible capital. If one entertains the possibility that intangible investments translates into capital stochastically, we find that plausible levels of macroeconomic volatility are compatible with highly variable corporate valuations, P/E ratios and stock returns.
Expanding the phenotypic and genetic spectrum of Chinese patients with congenital absence of vas deferens bearing CFTR and ADGRG2 alleles

Background : Congenital absence of vas deferens (CAVD) is a major cause of obstructive azoospermia. Mutations in CFTR and ADGRG2 are responsible for this disease. However, until now the genetic spectrum of the CFTR and ADGRG2 genes in Chinese population and the reasons of the differences from Caucasian cohorts were not clear. (i) To study the characteristic and functional consequences of CFTR and ADGRG2 mutations in Chinese CAVD patients. Materials : Patients were screened for mutations in CFTR by Sanger sequencing. Patients with only one or no mutations were further investigated by multiplex ligation-dependent probe ampliﬁcation analysis and direct sequencing of ADGRG2 gene. Bioinformatic analysis and structural modeling of proteins were performed. one Two novel mutations and p.Arg1008Gln) in ADGRG2 were detected. These novel mutations were predicted to be damaging by bioinformatics and were absent or extremely low frequency among our controls and databases. The genetic spectrum of Chinese CAVD patients revealed that the most common mutations were c.1210-12T[5], p.Ile556Val and p.Gln1352His, the last two of which were predicted to reduce the domains’ contacts and weaken adenosine triphosphate binding. This study illustrates the signiﬁcance of all exon sequencing in CFTR and ADGRG2 . A picture of the genetic spectrum of Chinese CAVD patients and the most common mutations can be described, which are different from Caucasian cohorts and Chinese CF patients.
