 We extend classical results on simple varieties of trees (asymptotic enumeration, average behavior of tree parameters) to trees counted by their number of leaves.  Motivated by genome comparison of related species, we then apply these results to strong interval trees with a restriction on the arity of prime nodes.  Doing so, we describe a filtration of the set of permutations based on their strong interval trees.  This filtration is also studied from a purely analytical point of view, thus illustrating the convergence of analytic series towards a non-analytic limit at the level of the asymptotic behavior of their coefficients.

International audience After extending classical results on simple varieties of trees to trees counted by their number of leaves, we describe a filtration of the set of permutations based on their strong interval trees. For each subclass we provide asymptotic formulas for number of trees (by leaves), average number of nodes of fixed arity, average subtree size sum, and average number of internal nodes. The filtration is motivated by genome comparison of related species. Nous commençons par étendre les résultats classiques sur les variétés simples d'arbres aux arbres comptés selon leur nombre de feuilles, puis nous décrivons une filtration de l'ensemble des permutations qui repose sur leurs arbres des intervalles communs. Pour toute sous-classe, nous donnons des formules asymptotiques pour le nombre d'arbres (comptés selon les feuilles), le nombre moyen de nœuds d'arité fixée, la moyenne de la somme des tailles des sous-arbres, et le nombre moyen de nœuds internes. Cette filtration est motivée par des problématiques de comparaison de génomes.

Through narratives and critical interrogations of classroom interactions, I sketch an argument for a co-constitutive relationship between qualitative research and pedagogy that imagines a more reflexive and socially just world. Through story, one comes to see an interplay between one's own experiences, one's own desires and one's community — I seek to focus that potential into an embodied pedagogy that highlights power and, as a result, holds all of us accountable for our own situated-ness in systems of power in ways that grant us potential places from which to enact change. Key in this discussion is a careful analytical point of view for seeing the world and a set of practices that work to imagine new ways of talking back.

Psycholinguistic research into metaphor processing is burdened with empirical problems as experiments provide diverging evidence on the impact of conventionality, familiarity and aptness, and with conceptual issues as the interpretation and operationalization of the three concepts mentioned, as well as the related predictions which can be drawn from theories of metaphor processing, are controversial in the literature. This paper uses tools of statistical meta-analysis in order to bring us closer to the solution of these problems and reveal future lines of research.

Wild olive trees have important potential, but, to date, the oil from wild olives has not been studied significantly, especially from an analytical point of view. In Spain, the wild olive tree is called “Acebuche” and its fruit “Acebuchina”. The objective of this work is to optimize the olive oil production process from the Acebuchina cultivar and characterize the oil, which could be marketed as healthy and functional food. A Box–Behnken experimental design with five central points was used, along with the Response Surface Methodology to obtain a mathematical experimental model. The oils from the Acebuchina cultivar meet the requirements for human consumption and have a good balance of fatty acids. In addition, the oils are rich in antioxidants and volatile compounds. The highest extraction yield, 12.0 g oil/100 g paste, was obtained at 90.0 min and the highest yield of phenolic compounds, 870.0 mg/kg, was achieved at 40.0 °C, and 90.0 min; but the maximum content of volatile compounds, 26.9 mg/kg, was obtained at 20 °C and 30.0 min. The oil yield is lower than that of commercial cultivars, but the contents of volatile and phenolic compounds is higher.

This paper looks at compliance-gaining interaction in a Japanese elderly care facility from a conversation analytical point of view. Focus is on the various ways compliance is sought for by the caring staff with getting the residents out of bed and starting the daily morning care procedures. Three extracts are discussed in detail. The analysis shows how the residents in all three cases display clear signs of resistance to get up, but finally have to submit to the planned course of actions pursued by the care workers. A closer look at how this is played out in interaction suggests that the residents’ compliance is enforced rather than gained.

The article is devoted to the sociological understanding of the poverty analysis methodological aspects as a topical social problem of today. Despite the defining poverty eradication as the number one goal in the Millennium Declaration and the priority task of sustainable world development by 2030, numerous scientific/political discussions and practical recommendations for overcoming poverty, it remains one of the most acute socio-economic and moral-ethical problems of humankind. The manifestation of multiple poverty factors — situational, socio-demographic, socio-economic, socio-political, socio-cultural, institutional — only increases the need for a clear understanding of the root causes of the existence and reproduction of this phenomenon. Within capitalism, they consist of abandoning the principles of Keynesianism and the welfare state and the transition to the principles of neoliberalism, which determine the socio-economic essence of the society in today’s globalized world. It is no coincidence that analysts of all the most influential international organizations directly or indirectly recognize that the ineffectiveness of the fight against poverty is a consequence of the existing rules of modern social life. Poverty is an integral part of capitalism, one of the most acute and widespread forms of inequality and injustice inherent in this social order. The multifaceted nature of poverty phenomenon and the variety of approaches to its assessment led to the emergence of a giant thesaurus on these issues (absolute, relative, social, multidimensional poverty etc.). Identifying and assessing poverty, adequately to the complex realities of life, are essential points not only from a cognitive-analytical point of view but also for the elaboration of effective measures to overcome it.

By an analysis of the Danish Humanist Society and the Danish Atheist Society, the aim of this contribution is to consider one aspect of the borderland of the Danish model of religion. On the basis of a relational approach to the study of religion, I conclude that the Humanist Society from an analytical point of view is a religion while the Atheist Society is not. In this manner, the Humanist Society should be regarded as part of the Danish model of religion while the Atheist Society should not. Therefore, it may be argued that the borderland of the Danish model of religion is located between these two organisations.Dette bidrag undersøger en del af den danske religionsmodels grænseflade gennem en analyse af foreningerne Dansk Humanistisk Samfund og Ateistisk Selskab. På baggrund af et relationelt religionsbegreb konkluderes det, at Humanistisk Samfund analytisk set er en religion og dermed en del af den danske religionsmodel. Med hensyn til Ateistisk Selskab konkluderer analysen, at denne forening analytisk set ikke er en religion men snarere en religionspolitisk forening. Ateistisk Selskab er dermed ikke en del af den danske religionsmodel. Den danske religionsmodels grænseflade kan dermed siges at befinde sig imellem disse to organisationer

In search for efficiency, effectiveness and fiscal sustainability, governments gather more performance information than ever before. As many of them have sought to incorporate and use this kind of information in budgeting and planning documents, the main goal of this article is to discover how local government performance budgeting practices can be mapped by a survey in a way that enables international comparison. Three previous mapping endeavors served as preliminary guidelines to develop a refined index based on the dimensions measurement, incorporation and use of performance information which form a generally accepted logical sequence in the public management literature. Results for the case of 304 Flemish local governments show a huge variation in the way performance budgeting is practiced, as index scores vary from nearly zero to more than 76 percent. Although it seems that available performance information is incorporated fairly well, measurement and use are lacking. It can be concluded that measuring performance budgeting offers interesting insights in the way this kind of budgeting is practiced in local governments. Although, from an analytical point of view, it is not sufficient to fully grasp performance budgeting and this for several reasons discussed in the article.
