Fluidity and cytosolic Ca2+ concentration of circulating polymorphonuclear leukocytes at baseline in some chronic and acute clinical conditions: revi…
2016
Abstract. Objective: In this mini-review we describe the behavior of polymorphonuclear leukocyte (PMN) membrane fluidity and of PMN cytosolic Ca2+ concentration in some chronic and acute clinical conditions. Methods: PMN membrane fluidity was evaluated employing the fluorescent probe Fura-2AM, and PMN cytosolic Ca2+ concentration was evaluated using the fluorescent probe TMA-DPH. Results: From the determination of these two parameters investigated on resting PMNs, an almost constant increase in PMN cytosolic Ca2+ concentration in chronic clinical conditions, such as vascular atherosclerotic disease with and without diabetes mellitus, essential hypertension, chronic kidney disease, and diabe…
Ash in composting of source-separated catering waste.
2004
Our earlier experiments in small composters (220 l) indicated the favourable effect of ash from co-incineration of sorted dry waste on the composting of catering waste. The aim of this new study was to clarify further, at a scale of 10 m3, the feasibility of using similar ash as an additive in composting.Source-separated catering waste was mixed with bulking agent (peat and wood chips) and fuel ash from a small (4 MW) district heating power plant. Three compost mixes (CM) were obtained: CM I with 0%, CM II with 10% and CM III with 20 wt.% of fuel ash. These three different mixes were composted in a 10-m3 drum composter as three parallel experiments for 2 weeks each, from January to April 20…
CONTEMPORARY THEORIES OF ADULT LEARNING
2015
<p>Due to the adult learning theory transition from cognitive to comprehensive aspects, this article analyses contemporary theoretical notions about adult’s learning. In order to characterise the modern view on adult, the most recent insights into the education of whole adult person (P. Jarvis), three dimensions of learning (K.Illeris) and the critical theory contribution (S.D. Brookfield) will be discussed. All of mentioned, globally-renowned theorists are of the same opinion and contribute to the general adult learning theory – P. Jarvis pictures the learning process from a viewpoint of a human as holistic organism, K.Illeris develops his theory in relation to the pedagogical condit…
Lay definitions of happiness across nations: The primacy of inner harmony and relational connectedness
2016
In well-being research the term happiness is often used as synonymous with life satisfaction. However, little is known about lay people's understanding of happiness. Building on the available literature, this study explored lay definitions of happiness across nations and cultural dimensions, analyzing their components and relationship with participants' demographic features. Participants were 2799 adults (age range = 30-60, 50% women) living in urban areas of Argentina, Brazil, Croatia, Hungary, India, Italy, Mexico, New Zealand, Norway, Portugal, South Africa, and United States. They completed the Eudaimonic and Hedonic Happiness Investigation (EHHI), reporting, among other information, th…
Effects of defects on the tensile strength of short-fibre composite materials
2014
Abstract. Heterogeneous materials tend to fail at the weakest cross-section, where the presence of microstructural heterogeneities or defects controls the tensile strength. Short-fibre composites are an example of heterogeneous materials, where unwanted fibre agglomerates are likely to initiate tensile failure. In this study, the dimensions and orientation of fibre agglomerates have been analysed from three-dimensional images obtained by X-ray microtomography. The geometry of the specific agglomerate responsible for failure initiation has been identified and correlated with the strength. At the plane of fracture, a defect in the form of a large fibre agglomerate was almost inevitably found.…
Si j'aurai su, j'aurai pas venu" : éclairage stratégique sur le lancement simultané des deux " Guerre des Boutons "
2014
“If I knew, I will not come”: strategic insight on the simultaneous launch of the two Guerre des BoutonsThe purpose of this paper is to propose an insight on an unusual strategic situation in the movie industry: thesimultaneous launch on screens of two almost identical movies, La Guerre des Boutons. After recalling the stakesattached to the product launch in the film industry, a monograph devoted to this direct confrontation, supplementedby an analysis of the critics of spectators, is proposed. This analysis reveals determinants (the conflictand lack of control in the film industry) and consequences (sub-optimal strategy) of the temporal agglomeration.
Sustainable agriculture: Recognizing the potential of conflict as a positive driver for transformative change
2020
International audience; Transformative changes in agriculture at multiple scales are needed to ensure sustainability, i.e. achieving food security while fostering social justice and environmental integrity. These transformations go beyond technological fixes and require fundamental changes in cognitive, relational, structural and functional aspects of agricultural systems. However, research on agricultural transformations fails to engage deeply with underlying social aspects such as differing perceptions of sustainability, uncertainties and ambiguities, politics of knowledge, power imbalances and deficits in democracy. In this paper, we suggest that conflict is one manifestation of such und…
"Co-development of a decision support model for integrated weed management. Metamodelling and sensitivity analysis of a complex mechanistic model (FL…
2018
In order to reduce our use ofherbicides, we need a tool to design weedmanagement strategies relying on fewerherbicides. Weed management is complicatedand, together with necessity of schedulingoperations at long-term and the multiplicity ofcropping system impacts, it explains whymodels are so useful for designing innovativecropping systems. The aim of this thesis is todevelop a decision support system, intended forcrop advisors, reconciling crop protection andecosystem services Our approach consisted inidentifying the structure of the DSS ininteraction with future users while using anexisting research model, FLORSYS, for thebiophysical content of the tool. FLORSYS is a“virtual field” simulat…
Conceptions of teachership in the professional identity construction of adult educator graduates
2019
The aim of this study was to investigate the conceptions of teachership among graduates (n = 126) from a Finnish higher education study programme called Pedagogical Studies for Adult Educators. The conceptions of teachership comprise notions of teaching and of oneself as a teacher. Accordingly, the conceptions of teachership are viewed as one element in the process of constructing teacher identity. Currently, we have little knowledge about the professional identity construction of adult educators, even though there is a growing need for adult pedagogics in the changing professional life. Based on a qualitative thematic analysis of open-ended questionnaire data, three main conceptual categor…
The emergence of intangible capital : human, social, and intellectual capital in nineteenth century British, French, and German economic thought
2016
Since the late 1950s the concept of human capital, understood as the stock of knowledge, skills, and abilities that determine individual productivity, has become one of the central tools with which economists explain both individual success and economic growth. During the latter half of the 20th century complementing concepts such as social capital, meaning the value of social networks and norms of reciprocity, and intangible capital, meaning the investments in knowledge and innovation generation, have emerged. The term intellectual capital is sometimes used as a major concept to bind different forms of intangible capital. This study focuses on the conceptual equivalents of these ideas in 1…
