Lorenzo Luzuriaga and the Challenge of Global Education

This article inquires into a neglected but crucial feature of the works of Lorenzo Luzuriaga: his analysis and criticism of the processes of internationalisation in education which marked the post- Second World War period and which coincided with his long Argentine exile. In particular, the article analyses – through a discussion of his initial appreciation and following criticisms in regard to UNESCO’s normative guidelines and educative practices – the philosophical premises and the political implications of his last educative proposals. These will be shown to be conceived in tight connection and continuity with his preceding works. Moreover, this investigation will permit to recognize the remarkable contribution he offered to the enhancement of José Ortega y Gasset’s pedagogical theory within a changed political context characterised by a unique attempt of defining and institutionalising new values for a global education aimed to promote world peace.A paradigmatic historical event that still grounds the current debate on the nature and purposes of citizenship education and in which the active, social and political education proposed by Luzuriaga still constitutes an interesting critical reference

Exaggerated inflammation and monocytosis associate with diastolic dysfunction in heart failure with preserved ejection fraction: evidence of M2 macrophage activation in disease pathogenesis

BACKGROUND: Heart failure with preserved ejection fraction (HFPEF) is a major health problem associated with myocardial leukocyte infiltration, inflammation, and fibrosis. Monocyte and macrophage subsets play a role in HFPEF but have not been studied. We analyzed peripheral blood monocyte phenotype and plasma markers of monocyte activation in patients with HFPEF, asymptomatic LV diastolic dysfunction (aLVDD), and asymptomatic hypertension (aHTN).

METHODS AND RESULTS: Peripheral blood was collected from 23 aHTN, 30 aLVDD, and 30 HFPEF patients. Peripheral cytokines of classic/pro-inflammatory (tumor necrosis factor alpha, interleukin (IL) 12, IL-6, monocyte chemoattractant protein 1, C-X-C motif chemokine 10) and alternative/anti-inflammatory monocytes (chemokine-C-C motif ligand (CCL) 17, CCL-18, soluble CD163) were increased in aLVDD and HFPEF. Peripheral blood mononuclear cells and monocytes were purified and surface-stained for CD14, CD16, CD163, and CD206. Peripheral monocyte percentage was increased in aLVDD and HFPEF and correlated with echocardiographic LVDD indices. Classic/pro-inflammatory monocyte numbers were increased in aLVDD and HFPEF, and alternative/anti-inflammatory monocyte numbers were increased in HFPEF. CD163 M2-macrophage receptor was reduced in HFPEF. Culture of healthy donor monocytes (n = 3) with HFPEF patient-derived sera (n = 6) promoted M2 macrophage features as evidenced by altered morphology and genes (CD206, IL-10).

CONCLUSIONS: Increased peripheral inflammation, monocytosis, and monocyte differentiation to anti-inflammatory/profibrotic M2 macrophages likely associate with HFPEF and its precedent asymptomatic LVDD phase.

We need to talk about managerialism: On the Importance of values dialogue and renewal within Catholic schools

Whilst reports of value tensions between new managerialism and Catholic education have emerged as a key theme in the academic literature there remains little empirical understanding of how teachers negotiate these complex terrains in Catholic schools. Drawing on qualitative data from teachers in two Catholic post-primary schools in Northern Ireland, this paper sought to explore how Catholic teachers developed a distinctively Catholic ethos against a culture of ‘creeping managerialism’. The paper has shown that despite the predominance of managerial practices, tensions between managerialist values and the ‘Catholic ethos’ did not emerge in either context: in one school managerialism permeated the school and the Catholic ethos was constructed within this context. In the other school a staff process of spiritual renewal had consolidated a commitment to the Catholic faith and social inclusion. It was argued that the dialogical engagement around Catholic values may help Catholic schools defend against the harsher manifestations of managerialism without compromising the pupils’ capacity to realise their academic potential

Opportunity of integrated production of "Ceratophyllum demersum" in a nutrition trial with "Carassius auratus"

[EN]The integrated culture of fish and plant in a recirculated system is called aquaponics, where a mutual benefit have been demonstrated for the cocultured species. Today this practice is still not well known for the most studied consumed freshwater species, and almost nothing has been done for aquarium species. The objective of present work was to study the opportunity of growing one of the most selled aquarium plant coontail (Ceratophyllum demersum) in a coculture with the goldfish (Carassius auratus) from which a nutritional trial was planned.
