Education, Aspirations and Life Satisfaction
Full text linkThe idea that expanding work and consumption opportunities always increases people’s wellbeing is well established in economics but finds no support in psychology. Instead, there is evidence in both economics and psychology that people’s life satisfaction depends on how experienced utility compares with expectations of life satisfaction or decision utility. In this paper I suggest that expanding work and consumption opportunities is a good thing for decision utility but may not be so for experienced utility. On this premise, I argue that people may overrate their socioeconomic prospects relative to real life chances and I discuss how systematic frustration over unfulfilled expectations can be connected to people’s educational achievement. I test the model’s predictions on Italian data and find preliminary support for the idea that education and access to stimulating environments may have a perverse impact on life satisfaction. I also find evidence that the latter effect is mediated by factors such as gender and age. Indeed, the model seeks to go beyond the Italian case and provide more general insights into how age/life satisfaction relationships can be modelled and explained.education, opportunities, aspirations, life satisfaction, regret
Computational Chemistry Tools for Atomic Level Investigation of Clay Composites
Full text linkThe most common computational methods used for the investigation of molecular and periodic systems will be briefly described, with particular emphasis on those approaches that could be employed for the study of clay structures at the atomistic level. The first part of the chapter is mainly dedicated to the conceptual basis of density functional theory and its implementation for molecular and periodic systems. The tight binding approximation to density functional theory and its modern variants, particularly suitable for atomistic studies of large systems, is treated as well. Classical molecular mechanics and molecular dynamics methods, as well as the definition of force fields suitable for clay materials, are shortly discussed. In the second part, case studies of application of computational approaches for the characterization of structures and properties of clay materials (in particular, the halloysite nanotube) are reported
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
Student Entrepreneurship: Demographics, Competences and Obstacles
No full textIn this report, we use a population-based approach to explore the entrepreneurial activities of 61,115 students, alumni of the 64 Italian universities that are members of the AlmaLaurea consortium, in the second half of 2014. Data were collected through a newly developed section of the AlmaLaurea survey, which will be consolidated in future rounds to allow to continue mapping student entrepreneurship in Italy and to provide robust empirical evidence to longitudinal analyses. Our results show that student entrepreneurs represent 2.7% of the sample whereas nascent entrepreneurs and non-entrepreneurs account for 3.8% and 93.5%, respectively. We profile and compare the three groups across several dimensions, such as demographics, mobility, field of study, sources of stimuli and competences, perceived obstacles, and support for entrepreneurship. The results shed light on the timely and relevant, yet understudied, phenomenon of student entrepreneurship, offering implications for both policy and practice
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
