How are Journal Impact, Prestige and Article Influence Related? An Application to Neuroscience
The paper analyses the leading journals in Neurosciences using quantifiable Research Assessment Measures (RAM), highlights the similarities and differences in alternative RAM, shows that several RAM capture similar performance characteristics of highly cited journals, and shows that some other RAM have low correlations with each other, and hence add significant informational value. Alternative RAM are discussed for the Thomson Reuters ISI Web of Science database (hereafter ISI). The RAM that are calculated annually or updated daily include the classic 2-year impact factor (2YIF), 5-year impact factor (5YIF), Immediacy (or zero-year impact factor (0YIF)), Eigenfactor score, Article Influence score, C3PO (Citation Performance Per Paper Online), h-index, Zinfluence, PI-BETA (Papers Ignored - By Even The Authors), 2-year and historical Self-citation Threshold Approval Ratings (STAR), Impact Factor Inflation (IFI), and Cited Article Influence (CAI). The RAM are analysed for 26 highly cited journals in the ISI category of Neurosciences. The paper finds that the Eigenfactor score and PI-BETA are not highly correlated with the other RAM scores, so that they convey additional information regarding journal rankings, that Article Influence is highly correlated with some existing RAM, so that it has little informative incremental value, and that CAI has additional informational value to that of Article Influence. Harmonic mean rankings of the 13 RAM criteria for the 26 highly cited journals are also presented. Emphasizing the 2-year impact factor of a journal to the exclusion of other informative RAM criteria is shown to lead to a distorted evaluation of journal performance and influence, especially given the informative value of several other RAM.prestige;IFI;PI-BETA;STAR;eigenfactor;h-index;immediacy;zinfluence;C3PO;impact factor;article Influence;cited article influence
What Makes a Great Journal Great in Economics? The Singer Not the Song.
The paper is concerned with analysing what makes a great journal great in economics, based on quantifiable measures. Alternative Research Assessment Measures (RAM) are discussed, with an emphasis on the Thomson Reuters ISI Web of Science database (hereafter ISI). The various ISI RAM that are calculated annually or updated daily are defined and analysed, including the classic 2-year impact factor (2YIF), 5-year impact factor (5YIF), Immediacy (or zero-year impact factor (0YIF)), Eigenfactor score, Article Influence, C3PO (Citation Performance Per Paper Online), h-index, Zinfluence, PI-BETA (Papers Ignored - By Even The Authors), and two new RAM measure, the Self-citation Threshold Approval Rating (STAR) score and the Impact Factor Inflation (IFI) score. The ISI RAM data are analysed for the most highly cited journals in the ISI categories of Economics, Management, Business, and Business - Finance. The journals are chosen on the basis of 2YIF (including self citations by both author and journal). The application to these four ISI categories could be used as a template for other ISI categories in both the Social Sciences and the Sciences, and as a benchmark for newer journals in a range of ISI disciplines. In addition to evaluating high quality research in the most highly cited Economics journals, the paper also compares the most highly cited journals in Management, Business, and Business - Finance, alternative RAM, highlights the similarities and differences in alternative RAM criteria, finds that several ISI RAM capture similar performance characteristics for the most highly cited Economics, Management, Business and Business - Finance journals, determines that the Immediacy and PI-BETA scores are not highly correlated with the other ISI RAM, and hence conveys additional information regarding ISI RAM criteria. Harmonic mean rankings of the 12 RAM criteria for the most highly cited journals in the four categories are also presented. It was shown that emphasizing THE impact factor, specifically the 2-year impact factor, of a journal to the exclusion of other useful and illuminating RAM criteria, can lead to a distorted evaluation of journal performance and influence on the profession.IFI;PI-BETA;STAR;article influence;eigenfactor;h-index;immediacy;impact factors;measures;research assessment;zinfluence;C3PO
China's energy economy: a survey of the literature
RePECThis paper reviews literature on China’s energy economics, focusing especially
on: i) the relationship between energy consumption and economic growth, ii) China’s
changing energy intensity, iii) energy demand and energy -capital and -labor substitution,
iv) the emergence of energy markets in China, vi) and policy reforms in the energy
industry. After reviewing the literature, the study presents the main findings and suggests
some topics for further study
Democracy and early childhood: diverse representations of democratic education in post-dictatorship Portugal
Education systems are often expected to play a key role in developing, maintaining and promoting democratic values and behaviours. This is particularly apparent in Portugal where, after nearly half a century of dictatorship ending in 1974, democracy emerged as a central national aspiration, especially within Early Childhood Education (ECE). However, the ambiguity of the term “democracy” has allowed policymakers, academics and educators alike to promote diverse understandings of its meaning.
This article delves into the ambiguities of democracy, revealing its flexible and context-dependent nature through the diverse representations of democracy encountered in three early years settings in Portugal: a public (state) kindergarten, a not-for-profit kindergarten and a private kindergarten. Using interviews, documentary analysis and observations we illustrate the diverse ways in which democracy is represented in each setting. We classify these representations of democracy as structural, individual and collective. We argue that these reflect the different ideologies of the three types of setting that draw upon particular theoretical understandings and sociopolitical developments in Portugal’s educational history
Introducing strain-rate dependent work material properties into the analysis of orthogonal cutting
An analysis is presented in which cutting speed, depth of cut and
certain strain-rate dependent work material properties are taken into
account. Good agreement between theory and experiment is shown over a
wide range of cutting conditions
2014 Evaluation of Hybrid Bell Pepper Varieties for High Tunnel Production in Kansas
This is a compilation of 30 research trial reports from four land-grant universities in the Midwestern United States. Crops include cantaloupe, pickling cucumber, pepper, potato, pumpkin, summer squash and zucchini, sweet corn, tomato, and watermelon. Somecrops were evaluated in high tunnels or hoophouses. Most trials evaluated different cultivars or varieties. One report addressed plant spacing for sweet corn and one addressed soil block for production of tomato seedlings. A list of vegetable seed sources and a list of other online sources of vegetable trial reports are also included

Ten Things We Should Know About Time Series
Time series data affect many aspects of our lives. This paper highlights ten things we should all know about time series, namely: a good working knowledge of econometrics and statistics, an awareness of measurement errors, testing for zero frequency, seasonal and periodic unit roots, analysing fractionally integrated and long memory processes, estimating VARFIMA models, using and interpreting cointegrating models carefully, choosing sensibly among univariate conditional, stochastic and realized volatility models, not confusing thresholds, asymmetry and leverage, not underestimating the complexity of multivariate volatility models, and thinking carefully about forecasting models and expertisecointegration;unit roots;fractional integration;volatility;leverage;VARFIMA;asymmetry;forecasting models and expertise;long memory;thresholds
