La estructura lógica de la teoría general de Keynes: una crítica de Benetti
No full textThis article criticizes Benetti's article "The logical structure of Keynes's General Theory". I criticize Benetti' s claim that a sequence of three models is necessary in order to give a foundation to Keynes' concept of involuntary unemployment. Likewise, I criticize the view, first brought forward by Patinkin and taken up by Benetti, that chapter 19 of the General Theory constitutes the climax of Keynes' book and provides an explanation of involuntary unemployment in a flex-price context.Este artículo critica el de Benetti "La estructura lógica de la Teoría General de Keynes".

A combined approach based on ecosystem services and environmental justice: the case study of Circeo National Park, Italy
No full textStarting from its born, the Ecosystem Services (ES) approaches become important for linking human and nature, and for supporting different decision-making and management contexts, in particular conservation strategies, landscape and urban planning, and compensative policies. However, the ES literature has been criticized for adopting a homogenous approach to communities and failing to consider social diversity, power structures influencing access to benefits, and participation in the management of ES. Still, despite the growing body of literature on ES, considerations of Environmental Justice (EJ) tend to fall short in ES assessments and therefore in planning and policy. EJ scholarship has traditionally parsed out a framework of justice based on a trilogy of concerns: the distributional justice, that can provide a framework to focus on the spatial and temporal distribution of costs, benefits, and risks of ES; the recognitional justice, referring the recognition of people’s varying values associated with ES; and the procedural justice, that considers the participation in the procedures through which decisions are made about ES. The main goal of the present thesis is to explore in which extent an ES approach with an EJ lens can support the environmental governance. The research was developed in three main parts: a literature review, a systematic review, and an empirical application in Circeo National Park (Italy). Although the two fields seem to focus on two distinct aspects of the environment – the original idea of EJ revolved around the negative health impacts of environmental degradation and pollution, while ES highlights benefits of ecosystems beyond health –, the two literature reviews showed different meetings points. First, the literature review integrated the aspects of EJ in ES, exploring their interconnections, and considering EJ as an analytical approach to thinking about ES issues. Second, the systematic literature review investigated how the different approaches of ES and justice were used for real-world application, how they evolved over time, and which trends have followed in order to identify possible gaps. The systematic review explored the number and type (conceptual, review, or empirical) of publications, the geographical distribution and scale of case studies analysed, the ES and justice dimensions investigated, and the governance contexts explored. Lastly, the analysis of the case study was useful to apply the ES and EJ combined approach with the purpose of understanding how and why the ES conservation policies in Circeo National Park generated different benefits and costs among different groups within society and were related to diverse kind of injustices. The addition of an EJ lens in combination with the ES approach revealed local perceptions critical to ES trade-offs and identified different stakeholders’ objectives. The thesis highlighted that EJ can uncover existing and potential social conflicts between management and use, especially when conservation policies are applied without due consideration of the interests and needs of local communities. Moreover, EJ provides a well-developed lens to focus on fair treatment of all with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies
PAX2 and CAKUT Phenotypes: Report on Two New Variants and a Review of Mutations from the Leiden Open Variation Database
No full textPAX2 is a transcription factor expressed during embryogenesis in the eye, ear, CNS, and genitourinary tract, and is one of the major regulators of kidney development. Mutations in this gene are associated with papillorenal syndrome (PAPRS), a genetic condition characterized by optic nerve dysplasia and renal hypo/dysplasia. In the last 28 years, many cohort studies and case reports highlighted PAX2’s involvement in a large spectrum of kidney malformations and diseases, with or without eye abnormalities, defining the phenotypes associated with PAX2 variants as “PAX2-related disorders”. Here, we reported two new sequence variations and reviewed PAX2 mutations annotated on the Leiden Open Variation Database 3.0. DNA was extracted from the peripheral blood of 53 pediatric patients with congenital abnormalities of the kidney and urinary tract (CAKUT). PAX2 gene-coding exonic and flanking intronic regions were sequenced with Sanger technology. Two unrelated patients and two twins carrying one known and two unknown PAX2 variations were observed. The frequency of PAX2-related disorders in this cohort was 5.8%, considering all CAKUT phenotypes (16.7% in the PAPRS phenotype and 2.5% in non-syndromic CAKUT). Although PAX2 mutations have a higher frequency in patients with PAPRS or non-syndromic renal hypoplasia, from the review of variants reported to date in LOVD3, PAX2-related disorders are detected in pediatric patients with other CAKUT phenotypes. In our study, only one patient had a CAKUT without an ocular phenotype, but his twin had both renal and ocular involvement, confirming the extreme inter- and intrafamilial phenotypic variability
Fabrication of Biopassive Surfaces Using Poly(2-alkyl-2-oxazoline)s: Recent Progresses and Applications
No full textPoly(2-alkyl-2-oxazoline)s (PAOXAs) are emerging among the most promising nonionic alternatives to poly(ethylene glycol)s (PEGs), specifically in the modification and functionalization of biomaterials. Due to their chemical tailorability and robustness, coupled to their relatively easy synthesis, PAOXAs are increasingly applied as adsorbates to generate bioinert surfaces that prevent nonspecific contamination by proteins, cells and bacteria. Passivation of medical devices, sensors and cell-sensitive platforms with PAOXAs enables a nearly quantitative suppression of nonspecific biological contamination, while biopassivity is maintained over longer incubation times than those recorded for more degradable PEG-based coatings. Thanks to these unique advantages, surface modification strategies involving PAOXAs are expanding to nanomaterials, especially those applied in the fabrication of nanomedicine and bioimaging tools

Ecosystem services and justice of protected areas: the case of Circeo National Park, Italy
No full textProtected areas are key instruments for conserving biodiversity and landscapes. Yet, conservation initiatives are still often struggling to accommodate people’s needs, provoking conflicts, and lacking support from local communities. Our study combines environmental justice and ecosystem services approaches to provide a critical understanding of trade-offs between people’s interests and conservation goals in the case study of Circeo National Park (Italy). Applying a qualitative content analysis of different materials and using a survey of local residents, we focus on three main objectives: analysing the implementation of the ecosystem services framework in policy documents and exploring how different people value benefits from nature; investigating the decision-making process in terms of participation, information and communication strategies; and identifying how conservation policies generated different allocations of benefits, burdens and inequalities among social groups. The integrated approach applied in our study highlights ways to systematically uncover perceived injustices and identifies potential conflict lines. In the long run, this approach might help to increase the public acceptance of protected areas by fostering sustainability also in its often-overlooked social dimension
