The Early Years
Full text linkThis book is open access under a CC BY-NC-ND 3.0 IGO license. The Early Years analyzes the development of Latin American and Caribbean children and makes a compelling case for government intervention in what is instinctively a family affair. Spending on effective programs for young children is an investment that, if done well, will have very high returns, while failure to implement such programs will lower the returns on the hefty investments being made in primary, secondary, and higher education. Policies for young children belong at the core of a country's development agenda, alongside policies to develop infrastructure and strengthen institutions. However, if the services provided (or funded) by governments are to benefit children, they must be substantially better than what is currently being delivered in the region. This book offers suggestions for improving public policy in this critical area. ; Addresses Baby Boomer generation concerns about shaping the next generation of leaders and provides policy suggestions to do s
Achieving net-zero prosperity: how governments can unlock 15 essential transformations
No full textInternational audienceGetting to net-zero emissions is necessary to limit global warming to well under 2 °C and towards 1.5 °C, which are the temperature goals of the Paris Agreement. More than 50 countries globally have set targets to reach net-zero emissions, typically by 2050, and most others are working on similar goals. Achieving these targets requires transformations in the electricity, transport, agriculture, land-use, buildings, industry, and waste-management sectors. While solutions exist to transition to a carbon-neutral economy, including both technology and behavioral changes, which often come with economic, social, or development benefits, many barriers prevent their uptake. We compile evidence from the academic and gray literature to identify 15 sectoral transformations that allow the achievement of net-zero greenhouse gas emissions. We then list barriers that prevent their uptake, such as hurdles related to infrastructure, regulations, public and private finances, information, and political economy issues. Finally, we provide more than 50 examples of sector-level government interventions that can lift these barriers, such as building infrastructure, reforming regulations and subsidies, providing information and capacity building, and managing distributional impacts. Governments can use this information to inform the design of comprehensive climate strategies that translate the long-term net-zero emission goal into a roadmap of required transformations in each sector, and then work on designing and implementing government interventions at the national, regional, or local levels to enable them
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Is energy planning consistent with climate goals? Assessing future emissions from power plants in Latin America and the Caribbean
No full textAt least ten Latin American and Caribbean countries have pledged to achieve carbon neutrality. Has electricity planning in the region evolved towards reaching these goals? We compare power generation capacity in 2023 to announced plans in 2019. We then estimate committed emissions from existing and planned power plants - that is emissions that would result from the normal operations of these plants during their typical lifetime - and compare them to emissions from power generation in published IPCC scenarios. We find that fossil fuel planned capacity has decreased by 47% since 2019, mainly due to the cancellation of 50% of coal and 40% of gas projects, compared to an increase of 24% of renewable energy projects. But existing plants in the region will emit 6.7 GtCO2 during their lifespan, and if all planned plants are built, they will add 4.9 GtCO2, totaling 11.6 GtCO2, exceeding median carbon budgets for 1.5 and 2êC-consistent IPCC pathways (2.3 and 4.3 GtCO2). Natural gas power plants are the largest contributor to existing (62%) and planned (75%) emissions (versus 24% and 23% for coal). We evaluate emissions reduction strategies to achieve carbon budgets. Assuming no new coal plants comes into operation, announced gas and oil projects are canceled at the same rate as in the past four years, all fossil fueled plant lifetimes are reduced by 10 years, and all new natural gas displaces existing coal, committed emissions fall by 67%, meeting the 2êC budget, but still twice as large as the median 1.5êC budget. Our results suggest that while progress is being made, energy planning in the region is not yet consistent with global climate goals as reflected by the IPCC scenario database
