Desafíos contemporáneos para el socialismo en Cuba (A propósito de las reformas políticoeconómicas en la fase actual de la revolución)

This essay analyzes on the origin and impact of the amendment process currently undertaken by the Cuban government authorities considering it as the result of --what I call-- super structural imbalance. Such imbalance is caused by the application of the System for Management and Planning of the Economy. To our judgment, the process of amendment both structurally and super structurally conforms the new phase in the construction of the Socialism in the island from a coherent point of view to what it has been until now as a political constant of the revolution: the vindication of the human being as the promoter of its historical reality.

Preparation and assessment of immobilized laccase-based micro- and nanocatalysts for the degradation of anthropogenic compounds

Since the dawn of its presence on earth, the human being has been able to exploit the enzymes for its subsistence. More recent is the meeting between the enzymatic processes and the urgent need for technologies that aim to preserve our planet. In this field nowadays enzymatic catalysis is tested either to depollution/remediation as well as waste disposal. The work presented in this thesis, regarding both these two topics, is tailored on two European projects (EU 2020), MADFORWATER and TERMINUS respectively. Firstly, production of micro- and nanocatalysts via immobilization of laccases (a lignin-degrader enzyme) is performed. In the second part of the thesis laccase is applied to a tertiary treatment of wastewater with the aim to degrade 9 pharmaceutical active compounds in batch reactors. Despite several optimizations, poor degradation is reached and we did not proceed with the study of different bioreactor setups. Therefore, the focus is moved to a project concerning the production of smart multi-layer plastic packaging containing enzymes to improve the possibilities of recycling. In this field shielded nanocatalysts produced via coating techniques able to interact with redox mediators are investigated. The target substrate in this second project is produced in laboratory (i.e. polyurethane like compounds), starting from monomers whose degradation had already been tested, as a proof of concept. The first enzyme studied is still the laccase.

Per una semiotica evolutiva dell'apprendimento. Produzione segnica, abduzione ed exaptation nell'accesso alla literacy

Con questa ricerca si intende costruire una semiotica specifica che sia in grado di fare luce sui processi di apprendimento della lettoscrittura durante l’età evolutiva. È un campo di ricerca a cui hanno contribuito numerose discipline: la psicologia e le neuroscienze trattano la lettoscrittura come uno stato cognitivo a cui l’essere umano accede nel corso dello sviluppo individuale, mentre l’archeologia cognitiva e la linguistica considerano lo stesso fenomeno dal punto di vista della filogenesi culturale. Queste stesse discipline possono essere distinte in due categorie a seconda dell’adozione di una prospettiva internalista, in cui lettura e scrittura sono rappresentate come attività compiute dal cervello e dai neuroni, o di una prospettiva distribuita, in cui si tratta di studiare l’evoluzione e la presa in carico delle forme materiali della lingua scritta. Gli strumenti di una semiotica interpretativa e cognitiva consentono di mediare e tradurre tra queste prospettive differenti e rendere ragione del modo in cui l’apprendimento di una pratica culturale socialmente regolata e costruita a partire da forme materiali disponibili, produce profonde modificazioni a livello neurofisiologico, nei vincoli di un’architettura cerebrale che - per quanto plastica - pone divieti e passaggi obbligati. Questa ricerca propone un ruolo centrale della produzione segnica e dell’inferenza abduttiva nei processi di apprendimento, nel processo di acquisizione delle competenze fondamentali dell’emergent literacy (la scoperta del fonema e la phonemic awareness) e, conseguentemente, nei processi di riciclaggio ed exaptation che si danno a livello neurofisiologico.

The birth of a tragic hero(ine) On tragic excess in contemporary theatre

The idea of the tragic is unthinkable. It is precisely within the moment in which an ordinary human being, a heroine or a hero – incapable of scrutinizing fully their own position within the whole – is invited to respond, to accept or refuse it all, that the tragic unfolds, changing their life irremediably. What are the causes and the consequences of "god’s arrival", as in case of Dionysus who visits Pentheus’ home in Euripides’ "The Bacchae"? Through episodes in the stories of characters from Ancient Greek dramas – such as Oedipus, Antigone, Ajax, Io, through Dostoevsky’s or Kafka’s imagery, in Prince Myshkin’s, the Ridiculous Man’s or Gregor Samsa’s experiences, this doctoral research proposes to examine the aspects which compete in the creation of a tragic hero. Theatrical performances – such as Jan Fabre’s "Mount Olympus: To Glorify the Cult of Tragedy, a 24-Hour Performance", immersed in a cycle of life, death and re-birth; Oliver Frljić’s "Trilogija o hrvatskom fašizmu", in its careful analysis of the wounds of a heritage of war; and Cristian Ceresoli’s and Silvia Gallerano’s tragic testimony of an estranged, almost soulless body in "La Merda" – open up the dialogue on our contemporary idea of the tragic. This doctoral work chooses excess as its privileged channel through which to approach the concept of the tragic – by its nature elusive, hostile to any definition, strictly personal and, thus, visible only through one’s own lens. In an excess of pain, devotion, desire, rage, arrogance or beauty, opposites collide, time concentrates into a moment and the hero is invited to choose, to live or die, to transform.

Innovation in conceptual design of chemical processes

Nowadays, the chemical industry has reached significant goals to produce essential components for human being. The growing competitiveness of the market caused an important acceleration in R&D activities, introducing new opportunities and procedures for the definition of process improvement and optimization. In this dynamicity, sustainability is becoming one of the key aspects for the technological progress encompassing economic, environmental protection and safety aspects. With respect to the conceptual definition of sustainability, literature reports an extensive discussion of the strategies, as well as sets of specific principles and guidelines. However, literature procedures are not completely suitable and applicable to process design activities. Therefore, the development and introduction of sustainability-oriented methodologies is a necessary step to enhance process and plant design. The definition of key drivers as support system is a focal point for early process design decisions or implementation of process modifications. In this context, three different methodologies are developed to support design activities providing criteria and guidelines in a sustainable perspective. In this framework, a set of key Performance Indicators is selected and adopted to characterize the environmental, safety, economic and energetic aspects of a reference process. The methodologies are based on heat and material balances and the level of detailed for input data are compatible with available information of the specific application. Multiple case-studies are defined to prove the effectiveness of the methodologies. The principal application is the polyolefin productive lifecycle chain with particular focus on polymerization technologies. In this context, different design phases are investigated spanning from early process feasibility study to operative and improvements assessment. This flexibility allows to apply the methodologies at any level of design, providing supporting guidelines for design activities, compare alternative solutions, monitor operating process and identify potential for improvements.

"Philosophy in the flesh" : being human with Clarice Lispector

According to Lakoff "thought is embodied, that is, the structures used to put together our conceptual systems grow out of our bodily experience and make sense in terms of it; moreover, the core of our conceptual systems is directly grounded in perception, body movement and experience of a physical and social character" (1987). If we read Lispector’s work as an oxymoron, an interplay between the basic magma of life and the metaphysical perplexities it generates, we will find at least three areas of description: devouring and eating, primordial substances and the animals. This paper proposes to show Lispector's use of "philosophy in the flesh" in some of her most representative works like “Uma História de tanto amor”, Uma Aprendizagem ou O Livro dos Prazeres or A Maçã no Escuro.

The intangible aspects of architectural spaces that influence human well-being

En utilisant des approches qualitative and quantitative cette thèse démontre que les aspects intangibles des espaces architecturaux influencent le bien-être humain. Le but est de faire savoir que les espaces intérieurs ont un impact sur le bien-être et que l’architecture peut être considérée comme une solution pour satisfaire les besoins des usagers. Dans la première étude, l’approche qualitative est explorée en utilisant la narration pour identifier les aspects intangibles des espaces intérieurs qui affectent le bien-être. Une discussion s’articule autour du Modèle de Réponses Expérientielles des Humains (Model of Human Experiential Responses to Space) et de son importance comme outil pour déterrer les caractéristiques environnementales qui influencent le bien-être et qui peut être utile pour les professionnels du design. Les résultats démontrent que 43 catégories sont interprétées comme étant des aspects intangibles et servent de canevas pour trois autres études. Les résultats démontrent que certaines caractéristiques environnementales similaires dans les résidences et les bureaux augmentent le sentiment de satisfaction et de bien-être. Dans la deuxième étude, une approche quantitative est explorée en utilisant les neurosciences et l’architecture afin de mesurer comment les espaces architecturaux affectent le bien-être. Le concept de neuroscience / environnement / comportement est utilisé où huit corrélats neuroscientifiques (Zeisel 2006) sont investigués afin de mesurer les effets du cerveau sur les espaces architecturaux. Les résultats démontrent que l’environnement peut affecter l’humeur, le niveau d’attention et le niveau de stress chez les humains et peut également augmenter leur performance. Les deux études contribuent aux connaissances que les caractéristiques environnementales affectent l’humeur et le niveau de satisfaction de la même façon dans les espaces résidentiels et dans les espaces de bureaux. Un bon environnement qui énergise les employés peut affecter leur performance au travail de façon positive (Vischer 2005).

(Re)enchanting geography? The nature of being critical and the character of critique in human geography

Enchantment is a term frequently used by human geographers to express delight, wonder or that which cannot be simply explained. However, it is a concept that has yet to be subject to sustained critique, specifically how it can be used to progress geographic thought and praxis. This paper makes sense of, and space for, the unintelligibility of enchantment in order to encourage a less repressed, more cheerful way of engaging with the geographies of the world. We track back through our disciplinary heritage to explore how geographers have employed enchantment as a force through which the world inspires affective attachment. We review the terrain of the debate surrounding recent geographical engagements with enchantment, focusing on the nature of being critical and the character of critique in human geography, offering a new ‘enchanted’ stance to our geographical endeavours. We argue that the moment of enchantment has not passed with the current challenging climate; if anything, it is more pressing.

Värdigt liv och välbefinnande, enligt vem? : en kvalitativ studie om brukare och biståndshandläggares beskrivningar av ett värdigt liv och välbefinnande : Dignity and well-being, according to whom? : a qualitative study of elderly and assistance officer´s descriptions of a dignified life and wellbeing

We are two students named Susanne Grönlund and Anna Zaar and have jointly worked together this c-essay called "dignity and well-being according to whom? The paper is written at Högskolan dalarna in Falun.The purpose of this study was to investigate how the elderly and assistance officer describes dignity and well-being and how it is consistent with the government's bill on the national values that the National Board has developed.Our empirical study consists of four qualitative interviews, two older people dependent on community care and two assistance officers. The study's theoretical basis is Antonovsky's salutogenic approach and SOC. The survey focuses on different themes such as dignity, integrity, participation, treatment, wellbeing, security and meaningfulness which are also central themes in the Government Bill on the national values for elderly.The results show that the respondents believe that a life of dignity is difficult to define and also a subjective experience. The results also show a consistency between what the elderly, assistance officer and the national values that define dignity and well-being. Social Services Act, national values should serve as a starting point for municipalities to improve elderly care, thereby creating a sense of coherence for the individual. Keywords: Elder care, dignity, integrity, participation, attitude, well-being, security and meaningfulness.
