Trends in Microbiology publications: are classic scientific journals condemned to extinction?
2020
ABSTRACT Scientific journals have played an essential role in the diffusion of research breakthroughs. For many years there was no competition between journals, but, in recent decades they have become categorized by a careful assessment of their published contents based on several metric parameters. Of greater note, the ‘prestige index’ has become an essential tool used by public and private institutions to develop their scientific policy. Thus, the evaluation of research staffs, the concession of grants or fellowships and even the scholarly reputation and academic positions are mainly founded on a given journal's ‘quality’. As a consequence, the prestige of some journals has gone up, based…
Chapter 4 Iron Dynamics in the Rhizosphere
2008
Abstract Iron is an essential micronutrient for most organisms due to its role in fundamental metabolic processes. In cultivated soils, soil solution iron is mostly oxidized [Fe(III) species] unless local anoxic conditions develop. The concentration of these Fe(III) species is small in soil solution due to the low solubility of ferric oxides, oxyhydroxides, and hydroxides, which is minimal at neutral and alkaline pH. In the rhizosphere, iron concentration in the soil solution is even lower because of its uptake by aerobic organisms (plants and microorganisms), leading to a high level of competition for Fe(III). In order to face iron competition, these organisms have evolved active uptake st…
Role of biological control agents and physical treatments in maintaining the quality of fresh and minimally-processed fruit and vegetables
2019
International audience; Fruit and vegetables are an important part of human diets and provide multiple health benefits. However, due to the short shelf-life of fresh and minimally-processed fruit and vegetables, significant losses occur throughout the food distribution chain. Shelf-life extension requires preserving both the quality and safety of food products. The quality of fruit and vegetables, either fresh or fresh-cut, depends on many factors and can be determined by analytical or sensory evaluation methods. Among the various technologies used to maintain the quality and increase shelf-life of fresh and minimally-processed fruit and vegetables, biological control is a promising approac…
Place and space in home-making processes and the construction of identities in transnational migration
2016
AbstractIn this era of increasing migration and the trend of growing social, political, and cultural integration worldwide, it is questionable whether the concept of home in its traditional meaning still applies or has to be redefined. Many social scientists agree that the mobile individual of the twenty-first century has become uprooted and thus disoriented or that the idea of home has lost its significance. Since home is still closely tied to one’s identity, the current discussions on the construction of identity must also be incorporated in the analytical processes of home-making. The objective is to point out new ways of understanding the idea of home by taking into consideration and an…
The Portret of a Contemporary Child and Youngster in the Global Education Space
2018
The world of transformations changes radically the education process. Theoreticians and practitioners of pedagogy recognize that methods and strategies consolidated over centuries very often have become ineffective in modern education practice. Therefore, the researchers' interest in childhood studies nowadays is natural. They define children's and youngster`s culture as different, unknown and incomprehensible. The researchers initiate a number of questions that need to be answered in order to cooperate with children and youngsters in school and in the family. How can teachers work efficiently in the modern school? How should adults implement modern pedagogical goals and which pedagogical m…
Spatial Perspective on Everyday Transitions Within a Toddler Group Care Setting
2017
This chapter builds on spatial approaches to study everyday life, and in particular to consider Henri Lefebvre’s (1901–1991) theory on the social production of space. Lefebvre’s ideas on the social production of space are based on a dynamic “spatial triad” of conceived (representations of space), perceived (socio-spatial practices), and lived space (representational space). The aim of this chapter is to discuss, by building on Lefebvre’s approach, the spatial dynamics involved within the small-scale (horizontal) transitions for children in toddler group care. The discussion is based on a study where one Finnish day care group for 1- to 3-year-olds was investigated by applying a spatial, rel…
Teacher Guidance in Mathematical Problem-Solving Lessons: Insights from Two Professional Development Programs
2019
When implementing a problem-solving lesson, the teacher needs to provide students appropriate guidance during problem solving. This demanding task requires understanding students’ work in progress and giving them necessary help without constraining their thinking. In this article, we share insights from two professional development programs on how teachers guided students’ problem solving and how they reflected on these instances. One of the programs included Finnish pre-service teachers, while the other program included US in-service teachers. We analyzed video-recorded problem-solving lessons from 16 Finnish and 2 US teachers in grades 6–9. We found two themes about teacher guidance of st…
Professional Embodiment: Walking, Re-engagement of Desk Interactions, and Provision of Instruction during Classroom Rounds
2018
Abstract Unlike continuous whole-class (plenary) interaction, independent task work involves incipient teacher–student talk, as the teacher typically ‘makes rounds’ to engage in brief desk interactions with students. This article draws on multimodal conversation analysis to investigate how teacher movement during tasks offers resources for re-engaging in desk interactions and offering task-related guidance. The focus is on teachers’ walking trajectories and ways of positioning the body, and students’ orientation to them, in (i) (pre-)opening moments of a desk interaction, and (ii) during a subsequent instructional turn that guides students with the ongoing task. The analysis shows how the p…
A New Paradigm in Interactive Evolutionary Multiobjective Optimization
2020
Over the years, scalarization functions have been used to solve multiobjective optimization problems by converting them to one or more single objective optimization problem(s). This study proposes a novel idea of solving multiobjective optimization problems in an interactive manner by using multiple scalarization functions to map vectors in the objective space to a new, so-called preference incorporated space (PIS). In this way, the original problem is converted into a new multiobjective optimization problem with typically fewer objectives in the PIS. This mapping enables a modular incorporation of decision maker’s preferences to convert any evolutionary algorithm to an interactive one, whe…
Group Analysis and the Self: The Political-Environmental-Transpersonal
1996
In this paper the authors try to put the basis for a new sense of group analysis, meant as the psychology of the field and the future, able to unblock saturated sets of meanings. Their work with groups has shown that there is a time in the group analytic process in which the individual explores the possibility of changeover. That time is also the space for the foundation of a new Self: the space for the difference, the space for the fight for giving and receiving'.
