Orígenes históricos y sociales de la regulación y la acreditación de la educación superior para la garantía de la calidad

A comienzos del nuevo milenio, la garantía de la calidad en la educación superior en el contexto de la globalización despierta mucho interés. Hay muchas modalidades de educación superior y definiciones del significado del término, del mismo modo que las ha habido con términos como «escuela universitaria», «academia» y «universidad» en el pasado. Las tendencias y las tensiones actuales reciben la influencia del discurso existente sobre las funciones de las instituciones de educación superior y las respuestas gubernamentales a los resultados neoliberales, como el concepto de las «universidades de rango mundial» y las tablas de clasificación de universidades, nacionales y mundiales.Peer Reviewe

Supporting innovation and the use of technologies in accountability initiatives: lessons from Making All Voices Count

Making All Voices Count was an international initative that harnessed the power of innovation and new technologies to support effective, accountable governance. Focusing on six countries in Africa and Asia, the programme was implemented by a consortium of implementing partners, and used funding from four donors to make grants to support new ideas that amplified the voices of citizens, and enabled governments to listen and respond. From the start, Making All Voices Count was also a learning programme. The objective of this learning was not only to bring about change during the programme’s life cycle, but also to leave a legacy that would help to ensure that future governance programmes and initiatives seeking to capitalise on the transformative potential of innovation and technology are more informed, inclusive and impactful. This programme learning report emerged from a wider process of analysing, discussing and synthesising the data and learning from the programme, which wove together evidence-based learning about technology for accountable governance initiatives with experiential learning on how best to support such work. The report highlights five of the lessons learned from Making All Voices Count about how – and how not – to run large, complex programmes that intend to support innovation in governance.DFIDSidaOmidyar NetworkUSAI

AntagomiR directed against miR-20a restores functional BMPR2 signalling and prevents vascular remodelling in hypoxia-induced pulmonary hypertension

Aims Dysregulation of the bone morphogenetic protein receptor type 2 (BMPR2) is a hallmark feature that has been described in several forms of pulmonary hypertension. We recently identified the microRNA miR-20a within a highly conserved pathway as a regulator of the expression of BMPR2. To address the pathophysiological relevance of this pathway in vivo, we employed antagomiR-20a and investigated whether specific inhibition of miR-20a could restore functional levels of BMPR2 and, in turn, might prevent pulmonary arterial vascular remodelling. Methods and results For specific inhibition of miR-20a, cholesterol-modified RNA oligonucleotides (antagomiR-20a) were synthesized. The experiments in mice were performed by using the hypoxia-induced mouse model for pulmonary hypertension and animal tissues were analysed for right ventricular hypertrophy and pulmonary arterial vascular remodelling. Treatment with antagomiR-20a enhanced the expression levels of BMPR2 in lung tissues; moreover, antagomiR-20a significantly reduced wall thickness and luminal occlusion of small pulmonary arteries and reduced right ventricular hypertrophy. To assess BMPR2 signalling and proliferation, we performed in vitro experiments with human pulmonary arterial smooth muscle cells (HPASMCs). Transfection of HPASMCs with antagomiR-20a resulted in activation of downstream targets of BMPR2 showing increased activation of Id-1 and Id-2. Proliferation of HPASMCs was found to be reduced upon transfection with antagomiR-20a. Conclusion This is the first report showing that miR-20a can be specifically targeted in an in vivo model for pulmonary hypertension. Our data emphasize that treatment with antagomiR-20a restores functional levels of BMPR2 in pulmonary arteries and prevents the development of vascular remodellin

Mitotic stress is an integral part of the oncogene-induced senescence program that promotes multinucleation and cell cycle arrest

Oncogene-induced senescence (OIS) is a tumor suppression mechanism that blocks cell proliferation in response to oncogenic signaling. OIS is frequently accompanied by multinucleation; however, the origin of this is unknown. Here, we show that multinucleate OIS cells originate mostly from failed mitosis. Prior to senescence, mutant H-RasV12 activation in primary human fibroblasts compromised mitosis, concordant with abnormal expression of mitotic genes functionally linked to the observed mitotic spindle and chromatin defects. Simultaneously, H-RasV12 activation enhanced survival of cells with damaged mitoses, culminating in extended mitotic arrest and aberrant exit from mitosis via mitotic slippage. ERK-dependent transcriptional upregulation of Mcl1 was, at least in part, responsible for enhanced survival and slippage of cells with mitotic defects. Importantly, mitotic slippage and oncogene signaling cooperatively induced senescence and key senescence effectors p21 and p16. In summary, activated Ras coordinately triggers mitotic disruption and enhanced cell survival to promote formation of multinucleate senescent cells

Cross modal perception of body size in domestic dogs (Canis familiaris)

While the perception of size-related acoustic variation in animal vocalisations is well documented, little attention has been given to how this information might be integrated with corresponding visual information. Using a cross-modal design, we tested the ability of domestic dogs to match growls resynthesised to be typical of either a large or a small dog to size- matched models. Subjects looked at the size-matched model significantly more often and for a significantly longer duration than at the incorrect model, showing that they have the ability to relate information about body size from the acoustic domain to the appropriate visual category. Our study suggests that the perceptual and cognitive mechanisms at the basis of size assessment in mammals have a multisensory nature, and calls for further investigations of the multimodal processing of size information across animal species

Lifespan extension and the doctrine of double effect

Recent developments in biogerontology—the study of the biology of ageing—suggest that it may eventually be possible to intervene in the human ageing process. This, in turn, offers the prospect of significantly postponing the onset of age-related diseases. The biogerontological project, however, has met with strong resistance, especially by deontologists. They consider the act of intervening in the ageing process impermissible on the grounds that it would (most probably) bring about an extended maximum lifespan—a state of affairs that they deem intrinsically bad. In a bid to convince their deontological opponents of the permissibility of this act, proponents of biogerontology invoke an argument which is grounded in the doctrine of double effect. Surprisingly, their argument, which we refer to as the ‘double effect argument’, has gone unnoticed. This article exposes and critically evaluates this ‘double effect argument’. To this end, we first review a series of excerpts from the ethical debate on biogerontology in order to substantiate the presence of double effect reasoning. Next, we attempt to determine the role that the ‘double effect argument’ is meant to fulfil within this debate. Finally, we assess whether the act of intervening in ageing actually can be justified using double effect reasoning

Coverage of endangered species in environmental risk assessments at EFSA

The EFSA performs environmental risk assessment (ERA) for single potential stressors such as plantprotection products, genetically modified organisms and feed additives, and for invasive alien speciesthat are harmful to plant health. This ERA focusses primarily on the use or spread of such potentialstressors in an agricultural context, but also considers the impact on the wider environment. It isimportant to realise that the above potential stressors in most cases contribute a minor proportion ofthe total integrated pressure that ecosystems experience. The World Wildlife Fund listed the relativeattribution of threats contributing to the declines in animal populations as follows: 37% fromexploitation (fishing, hunting, etc.), 31% habitat degradation and change, 13% from habitat loss, 7%from climate change, and only 5% from invasive species, 4% from pollution and 2% from disease. Inthis scientific opinion, the Scientific Committee gathered scientific knowledge on the extent of coverageof endangered species in current ERA schemes that fall under the remit of EFSA. The legal basis andthe relevant ecological and biological features used to classify a species as endangered areinvestigated. The characteristics that determine vulnerability of endangered species are reviewed.Whether endangered species are more at risk from exposure to potential stressors than other non-target species is discussed, but specific protection goals for endangered species are not given. Due toa lack of effect and exposure data for the vast majority of endangered species, the reliability of usingdata from other species is a key issue for their ERA. This issue and other uncertainties are discussedwhen reviewing the coverage of endangered species in current ERA schemes. Potential tools, such aspopulation and landscape modelling and trait-based approaches, for extending the coverage ofendangered species in current ERA schemes, are explored and reported
