Does Board Collective Suitability Affect Performance and Risk? Evidence from European Banks
Authors: Di Battista Maria Luisa , Nieri Laura , Resta Marina , Tanda Alessandra
Published: January 2022

This paper analyzes the features of the boards of large listed European banks and their degree of “collective suitability” as formalized by the Capital Requirements Directives (CRD4) and evaluates whether closer proximity to the collective suitability regulatory paradigm affects banks’ performance, risk and risk-adjusted performance. We leverage Self-Organizing Maps (SOMs) to analyze board features and suitability (i.e. competence, diversity, independence and time commitment) jointly as a multifaceted, non-linear combination of all board variables, rather than evaluating the single variables individually as in the mainstream literature. Using a hand-collected dataset based on numerous features of boards of directors, we find that European banks’ boards can be classified in four different board archetypes characterized by different degrees of collective suitability. Our findings also suggest positive relationships between the degree of collective suitability and performance, risk-adjusted performance, and risk, confirming that the regulatory provisions on governance are going in the right direction, enhancing effective and prudent management.
Economic impacts of partial harvesting: Mitigating mid-term timber supply shortages as a result of pest outbreaks
Authors: Jensen Torben , Lussier Jean-Martin
Published: January 2022

Natural disturbances such as pest outbreaks have a significant impact on forest dynamics and services, including the loss of mature stands. From a wood production perspective, these disturbances can lead to long-lasting imbalances in the overall age-class structure of the forest, potentially resulting in a shortage of mature harvestable stands.

Researchers from Natural Resources Canada’s (NRCan) Canadian Forest Service (CFS) have made a timber supply analysis of the Dunière forest located in the centre of the Gaspé Peninsula (Québec). This region suffers from an age-class structure imbalance caused by an eastern spruce budworm (ESB) outbreak that ended in 1984, and is consequently facing a reduced annual allowable cut, leading to long- term implications for the regional forest sector. The authors suggest that partial harvesting – the removal of a proportion of timber in a mature stand several years before a final cut is carried out – is a promising opportunity in the ESB-affected area for mitigating mid-term timber supply shortages by smoothing the fibre supply over time.
Regeneration of black ash (Fraxinus nigra Marsh.) in hardwood swamps of the Great Lakes – St. Lawrence Forest Region
Authors: Springer Amanda , Dech Jeffery P.
Published: January 2022

An inductive, ordination-based approach was used to explore patterns in the microenvironment and natural regeneration of black ash across a range of representative stands in the central Ontario portion of the Great Lakes -St. Lawrence Forest Region (GLSL) near Lake Nipissing, Ontario, Canada. The objective of this study was to describe patterns of regeneration of black ash and determine the associations between multiple indicators of black ash regeneration success and biotic and abiotic factors. Using a randomized sampling design with specific selection criteria, 12 black ash stands were sampled, each with three 400 m2 circular sample plots that contained three 4 m2 sub-plots. A suite of environmental variables such as elevation, topographic wetness index, slope, and soil characteristics (percent moisture, pH, total nitrogen, exchangeable phosphorus, potassium, magnesium) were determined for each stand. Variables capturing regeneration potential, including density, diameter, and height of all germinants, seedlings, saplings and sprouts were also collected. A sample of 15 dominant or co-dominant trees in each stand, as well as numerous black ash seedlings, saplings and sprouts were examined using dendrochronological methods to estimate ages. Principal component analysis ordinations were performed exploring the variation in environment and black ash regeneration variables among the stands. High soil moisture and the presence of canopy gaps, (as indicated by high standard deviation of canopy closure), were key variables associated with greater abundance of regeneration. Black ash was the dominant species in all stands, which were also generally characterized by a common reverse-J diameter distribution. It was observed that black ash in the sapling layer reached substantial ages (up to 60 years), indicating they are capable of withstanding long periods of suppression below the canopy. Collectively, these findings suggest that black ash-dominated stands in the study area are regenerating in multiple cohorts. Based on these patterns, it appears that regeneration in these stands is occurring through gap-phase mechanisms, suggesting single tree selection as the best management option for black ash in the GLSL.

Comparative Assessment of Functional Outcomes of Surgical Treatment in Patients with Distal Radial Fractures
Authors: Florek Jakub , Georgiew Filip , Kotela Ireneusz
Published: January 2022

Background. Unstable and comminuted distal radial fractures require surgical treatment by percutaneous insertion of Kir­schner wires, open reduction and fixation with a non-locking or locking plate or with an external device. The aim of this paper was to try to answer the following question: are there differences in functional treatment outcomes in patients after surgery with the use of Kirschner wires vs LCP plate fixation?
Material and methods. The study group included 100 patients after surgical treatment by closed reduction and simple fixation with Kirschner wires (50 patients) and by open reduction and LCP locking plate fixation (50 patients). The study assessed the following parameters: global grip strength, pain severity in a VAS scale, range of motion, functional status of the wrist based on the Fernandez classification, quality of life according to the QuickDASH score, and the frequency of complications. These parameters were assessed at 6 and 12 months after surgery.
Results. An assessment of the treatment outcomes at 6 and 12 months after surgery showed statistically significant differences between the treatment methods in the following parameters: pain severity, global grip strength and range of motion in the sagittal plane. A comparison of the functional status of the wrist at 6 and 12 months between the groups showed considerably worse results in the Kirschner wire fixation group. The frequency of postoperative complications at 12 months was 6% in the Kirschner wire fixation group and 2% in the LCP plate fixation group.
Conclusions. 1. Treatment outcomes were better in patients with distal radial fractures managed with LCP plate fixation. 2. The use of LCP plate fixation predisposes pa­tients to better ranges of mobility in the sagittal plane in the radiocarpal joint. 3.The values of global grip strength were higher in the group treated with LCP plate fixation. 4. Patients treated with LCP plates have better limb function and quality of life and lower pain intensity after treatment completion. 5. The number of complications was higher in pa­tients treated with Kirschner wire fixation.
Lateral Compression Sacral Fractures Have Less Favourable Outcome Compared to Crescent Fractures in Patients Less Than 50 Years Old
Authors: Hammad Abdullah Said , Abu-Sheasha Ghada Ahmed , Nafady Mahmoud , El-Bakour Ahmed
Published: January 2022

Background. Lateral compression (LC) accounts for a wide spectrum of pelvic ring injuries (PRIs). The primary aim of this study was to assess the health-related quality of life outcomes of surgically fixed LC crescent versus sacral fractures in patients less than 50 years old after high energy trauma.
Material and methods. We retrospectively reviewed the database for PRIs treated surgically from Decem­ber 2011 to January 2019 at our tertiary level trauma centre. The EuroQoL-5D (EQ5D5L) questionnaire was elec­tronically sent to all patients. Multiple linear regression was conducted to determine the predictors of quality-adjusted life-years (QALYs).
Results. The study included 37 patients. The mean age was 26 SD 9.46 years. The mean duration of follow-up was 3.78 (r:1-9) years. Twenty-one (56.8%) and 16 (43.2%) patients sustained sacral fractures and crescent fractures, respectively. Multi-regression analysis showed that any patient with LC injury without a sacral fracture is expected to have a utility value of QALY= 0.876. A reduction of 0.072 units in QALYs is expected in the presence of sacral fracture. About 71% of patients with sacral fractures were able to return to work and this probability increased by 40% among patients with crescent fractures (RR=1.4, p=.015).
Conclusions. 1. Younger patients with crescent fractures tend to have better quality of life (higher EQ5D and QALYs) compared to those with LC sacral fractures. 2. Moreover, patients with LC sacral fractures have less chan­ce to return to their pre-injury level of work compared to those with crescent fractures.

Profile of enzymes in samples of bacterial cellulose film treated with Trametes versicolor and
Coniophora puteana. The paper presents the results of research showing the profile of hydrolytic enzymes
synthesized by fungi that cause decomposition of wood during growth on film samples made of bacterial
cellulose. The performed analyzes allowed for the conclusion that the presence of cellulose in the culture
medium stimulates the fungal cells to synthesize full groups of enzymes that are not produced on the agarmaltose medium. Among the synthesized enzymes, both species of fungi produced two enzymes: β - glucosidase
and N-acetyl-β - glucuronidase with the highest observed activity.
A GEOMETRICAL SURFACE TEXTURE STUDY OF CYCLOID
DRIVE DISCS AFTER BENCH TESTS
Authors: Olejarczyk Krzysztof , Kalbarczyk Marek
Published: January 2022

The article presents the results of a geometrical surface texture study of cycloid drive discs after bench tests.
For this purpose, the working surfaces, such as peak and valley areas of the epicycloid and the holes inner
surfaces of both discs, were investigated using contact profilometry. From each surface, a transverse profiles
were extracted, before and after 50 cycles of bench test. The discs and the profiles were examined for signs
of wear and roughness changes. For each profile, the Ra and Rz roughness parameters were determined. On
the base of the obtained profiles and the values of roughness parameters, it can be stated that the assumed
test parameters provide stable working conditions, with an uninterrupted lubrication film, which results in
practically negligible and unmeasurable wear. Taking into account the operating specification of a helicopter
winch as an example of potential application of the presented cycloidal drive, the developed solution fulfils
the requirements concerning wear resistance.
THE IMPACT OF SELECTED PARAMETERS ON PRESSURE
DISTRIBUTION IN THE FACE THROTTLE OF A CENTRIFUGAL
PUMP AUTOMATIC BALANCING DEVICE
Authors: Tarasevych Yuliia , SOVENKO Nataliia
Published: January 2022

Face throttles are a necessary functional element of non-contact face seals and automatic balancing devices of
centrifugal pumps of different constructions. To calculate the hydrodynamic forces and moments acting on the
rotor and fluid flow through the automatic balancing device, it is necessary to know the pressure distribution
in the cylindrical and face throttle when considering all important factors which predetermine fluid flow.
The face throttle surfaces are moving, which leads to unsteady fluid flow. The movement of the walls of the
face throttle causes an additional circumferential and radial flow, which subsequently leads to the additional
hydrodynamic pressure components. The paper analyses viscous incompressible fluid flow in the face throttle
of an automatic balancing device taking into account the axial and angular displacements of throttle’s surfaces
and the inertia component of the fluid. The effect of local hydraulic losses as well as random changes in the
coefficients of local hydraulic resistance at the inlet and outlet of the throttle is analysed.
Philosophy in the Narrative Mode
Authors: Akasoy Anna Ayse
Published: January 2022

Histories of Arabic and Islamic philosophy tend to focus on texts which are systematic in nature and conventionally classified as philosophy or related scholarly disciplines. Philosophical principles, however, are also defining features of texts associated with other genres. Within the larger field of philosophy, this might be especially true of ethics and within the larger body of literature this might be especially the case for stories. Indeed, it is sometimes argued that the very purpose of storytelling is to reinforce and disseminate moral conventions. Likewise, the moral philosopher can be conceptualized as a homo narrans.The aim of this contribution is to apply the approach to narratives as a mode of debating ethical or moral principles to biographies of Alexander the Great. More than any other figure of the classical world, Alexander was religiously validated in the Islamic tradition due to his quasi-prophetic status as the ‘man with the two horns’ in the Qur’an. He appears prominently in the larger orbit of Arabic and Islamic philosophy as interlocutor and disciple of Aristotle and is adduced anecdotally in philosophical literature as an example to teach larger lessons of life. As a world conqueror, he provided an attractive model for those who sought to reconcile philosophical insight with worldly ambition.Focusing on biographies of Alexander, this article explores ethical principles which are inscribed in this body of literature and thus reads the texts as a narrativized form of philosophy. The analysis is comparative in two ways. Biographies of different periods and regions of the Islamicate world will be discussed, but comparisons with pre-Islamic biographies of Alexander (notably Roman biographies and the Alexander Romance) are included as well.
Ethical Turn in Legal Analogy
Authors: Opwis Felicitas
Published: January 2022

Al-Ghazālī’s articulation that the purposes of the divine Law (maqāṣid al-sharīʿa) are to attain maṣlaḥa for the five necessary elements of human existence was not only novel but had long-lasting influence on the way Muslim jurists understood the procedure of analogy (qiyās). The correctness of the ratio legis was determinable by its consequences in bringing about maṣlaḥa. This shift was possible only by intellectual shifts in understanding the relationship between ethics and law. This paper traces the development in conceptions of ethics and its impact on the procedure of analogy in three 5th/11th century predecessors of al-Ghazālī, namely al-Baṣrī, al-Dabbūsī, and al-Juwaynī. It shows that al-Ghazālī’s definition of the purposes of the Law was developed based on previous conceptual shifts in the ratio legis from being a sign for the ruling to reflecting the ethical content of the divine injunction.
Interplay of Religion and Philosophy in al-Tawḥīdī’s Political Thought and Practical Ethics
Authors: Alshaar Nuha
Published: January 2022

Although modern scholars tend to be sceptical of the role of religion in the formation of ethical and political thought in the Būyid period (334/945–440/1048), this article argues that both philosophy and religion, as envisioned by al-Tawḥīdī and his contemporaries, played an integral role in its creation. The analysis shows that modern concepts such as ‘humanism’ and ‘political philosophy,’ as applied to these authors and their texts, are not felicitous to the social and intellectual contexts in which they were produced. Through analysing al-Tawḥīdī’s ethical and political thought, certain modern assumed dichotomies, including scientific enquiry versus religious teaching, theoretical ethics versus practical ethics, and the social versus the personal, are reconsidered. The article argues that a contextual approach to al-Tawḥīdī and his peers should consider the encyclopaedic system of knowledge that shaped their thought and the interdisciplinary nature of their work where religious, philosophical, and literary elements are intertwined. The article highlights al-Tawḥīdī’s political thought, his active role as an intellectual and his attempt to disseminate knowledge based on two main beliefs: the role of knowledge linked to action in social life and reform, and a solid sense of the religious and moral responsibility of the scholar to offer advice to the leaders of the community. The concepts that he uses, such as maḥabba (love) and ṣadāqa (friendship) with its four foundational components, namely the soul (nafs), intellect (ʿaql), nature (ṭabīʿa), and morals (khulq), addressed social and political challenges in Būyid society and produced alternative moral and intellectual responses to sectarianism, social disintegration and the decline in morality, which were characteristic of the Būyid era.

Current Topics in Plastic Recycling
Authors: Anna Charitopoulou Maria , Alexopoulou Eleni , Alexiou Panagiotis , S. Achilias Dimitris
Published: January 2022

This chapter presents an overview of current trends in plastic recycling and focuses on specific topics of interest. Firstly, there are presented all methods used for plastic recycling, along with the advantages and disadvantages of each method. Extra attention is paid to chemical recycling and especially, pyrolysis (thermal and catalytic), which is an environmentally friendly method that results in the formation of value-added products. Emphasis is given on three case studies where there are difficulties as regards the recycling of the plastic part: polymeric blends, since the existence of mixed plastic wastes may be challenging for their recycling; plastics originating in multilayer packaging, since the multilayer packaging consists of various materials, including plastics, paper, and metals that may be an obstacle for the recycling of the plastic part; and brominated flame-retarded plastics from waste electric and electronic equipment (WEEE), since in this case safe handling is required in order to avoid environmental contamination and a pretreatment step before recycling may be of paramount importance. These three case studies along with the mentioned difficulties and suggestions in order to overcome them are presented here, with the aim of offering insights for future studies on the management of plastic materials.
The Role of Extracellular Vesicles in the Progression of Tumors towards Metastasis
Authors: Basu Bhaskar , Karmakar Subhajit
Published: January 2022

Extracellular vesicles (EVs) are cell-derived lipid membrane bound vesicles that serve as mediators of intercellular communication. EVs have been found to regulate a wide range of cellular processes through the transference of genetic, protein and lipid messages from the host cell to the recipient cell. Unsurprisingly, this major mode of intracellular communication would be abrogated in cancer. Ever increasing evidence points towards a key role of EVs in promoting tumor development and in contributing to the various stages of metastasis. Tumor released EVs have been shown to facilitate the transference of oncogenic proteins and nucleic acids to other tumor cells and to the surrounding stromal cells, thereby setting up a tumor permissive microenvironment. EVs released from tumor cells have been shown to promote extracellular matrix (ECM) remodeling through the modulation of neighboring tumor cells and stromal cells. EVs released from disseminated tumor cells have been reported to attract circulating tumor cells (CTCs) via chemotaxis and induce the production of specific extracellular matrix components from neighboring stromal cells so as to support the growth of metastatic cells at the secondary tumor site. Circulating levels of tumor derived EVs of patients have been correlated with incidence of metastasis and disease relapse.

Kidney stone disease is an oldest known and widespread medical condition characterised by its high prevalence in all over the world. Literature suggests that around 9–12% of population in industrialised countries have kidney stone disease in their lives with the 30–50% of reoccurrence rate. Because of high prevalence, recurrent and unpredictable nature of stone formation and its predominance mainly in adults contributes to the substantial impact on society, individual and health care system. In light of these trends, it’s imperative to use optimum preventive strategies to reduce the burden of kidney stone disease on individual and society. The aetiology of kidney stone disease is a multifactorial and it’s related to diet, environmental factors, genetics, metabolic syndromes and various life style factors. Its noteworthy that dietary and life style modification are the major contributors in the prevention of kidney stone reoccurrence. Dietary interventions aim to reduce the urinary abnormalities known to promote lithogenesis. Therefore, modification in the dietary factors is appealing way to patients and physicians in the treatment and prevention of stone recurrence as it is relatively inexpensive and safe. So, the present chapter is focusing on the role of dietary supplements in prevention of renal stones.
Understanding / Psychosis
Authors: Fukao Kenjiro
Published: January 2022

“Understanding” in Jaspers’ sense is the essential concept for defining psychosis, although its relationship is paradoxical, that is, psychosis is defined by un-understandability or inability to understand. Un-understandability means the inability of empathizing with the patient’s mind and implies the existence of a pathological process in the patient’s brain. The pivotal concept which makes psychotic patients be judged as irresponsible in forensic cases is disturbed self-understanding or un-understandability of their own intentions. It is suggested that self-disorder representing psychosis might be based on disturbed self-understanding.

Velocity Prediction Programs (VPPs) are commonly used to help predict and compare the performance of different sail designs. A VPP requires an aerodynamic input force matrix which can be computationally expensive to calculate, limiting its application in industrial sail design projects. The use of multi-fidelity kriging surrogate models has previously been presented by the authors to reduce this cost, with high-fidelity data for a new sail being modelled and the low-fidelity data provided by data from existing, but different, sail designs. The difference in fidelity is not due to the simulation method used to obtain the data, but instead how similar the sail’s geometry is to the new sail design. An important consideration for the construction of these models is the choice of low-fidelity data points, which provide information about the trend of the model curve between the high-fidelity data. A method is required to select the best existing sail design to use for the low-fidelity data when constructing a multi-fidelity model. The suitability of an existing sail design as a low fidelity model could be evaluated based on the similarity of its geometric parameters with the new sail. It is shown here that for upwind jib sails, the similarity of the broadseam between the two sails best indicates the ability of a design to be used as low-fidelity data for a lift coefficient surrogate model. The lift coefficient surrogate model error predicted by the regression is shown to be close to 1% of the lift coefficient surrogate error for most points. Larger discrepancies are observed for a drag coefficient surrogate error regression.
Infancia alterada en pleitos por la custodia de menores
Authors: Jabbaz Churba Marcela
Published: January 2022

In this article, the disputes of mothers and fathers about the custody and visitation of their sons and daughters are analyzed, through an interpretation of their narratives. It focuses on cases where divorce is conflictive, evidencing a significant presence of forms of gender-based violence, with and without a judicial complaint. Through stories, I analyzed the previous situation, the judicial process and the relations between the ex-partner once the definitive judicial measures had been taken in relation to the children. Nodal but not very visible elements are identified and analyzed at each moment of the judicial process: in the initial situation, the uncertainty experienced by the absence of rules of coexistence. Then, the difficulties posed by judicial rituals in showing complex situations and the mothers’ dilemma about whether or not to report the inconvenience their children may suffer for fear that they will not be believed. Finally, the emergence of new types of covert violence, such as financial abuse related to pensions and custody harassment. Divorces in which conflict becomes chronic can disrupt children’s daily lives.

En este artículo se analizan las disputas entre madres y padres por la custodia y el régimen de visitas de sus hijos e hijas, mediante una interpretación de sus narrativas. Se focaliza en los casos donde el divorcio es conflictivo, evidenciándose una presencia importante de formas de violencia de género, con y sin denuncia. A través de relatos, analizo la situación previa, el proceso judicial y las relaciones entre la expareja una vez que se han tomado las medidas judiciales definitivas con relación a las criaturas. En cada momento del proceso judicial se identifican y analizan elementos nodales pero poco visibles: en la situación inicial, la incertidumbre vivida por la ausencia de normas de convivencia. Luego, las dificultades que plantean los rituales judiciales para evidenciar situaciones complejas y el dilema de las madres sobre si informar o no de los malestares que pueden sufrir sus criaturas porque temen no ser creídas. Finalmente, la emergencia de nuevos tipos de violencia encubierta, como el abuso económico vinculado a las pensiones y el acoso de custodia. Los divorcios en los que el conflicto se vuelve crónico pueden alterar la vida cotidiana de las criaturas.
Prácticas culturales colaborativas y sociabilidad débil. Una caracterización a partir de experiencias autogestivas en Tijuana y Monterrey, México

Although research on collaborative artistic projects and practices tend to emphasize the social ties and even the production of communities that they enact, normally, this very research does not pay attention to the singularity of the forms of sociality produced. This article engages in a double task –namely, a theoretical definition and an analytical application– derived from the fieldwork undertaken in the Mexican cities of Tijuana and Monterrey by means of which we developed the notion of “weak sociality” to name the modes of relationships produced by cultural actors from civil society enrolled in independent spaces or projects. We hold that the sociality these strategies produce is conflictive, ephemeral, spatially bound and affective. Both, our theoretical stance as well as our fieldwork findings will make us conclude that the relationships produced in this microspaces –where conflict is productive, ephemerality means open ended negotiations and affect implies care– work as an unavoidable process for the politicization of artistic collaborative practice in the neoliberal city.

Si bien la investigación sobre prácticas y proyectos artísticos colaborativos suele enfatizar los lazos sociales e, incluso, la producción de comunidad que estos generan, es frecuente que no se atienda a la singularidad de las formas de sociabilidad que ahí se articulan. Este artículo propone un doble ejercicio, de definición teórica y de aplicación analítica, a partir del trabajo empírico realizado en las ciudades mexicanas de Tijuana y Monterrey. En nuestro análisis proponemos la noción de “sociabilidad débil” para nombrar los modos de relación producidos por agentes culturales de la sociedad civil en espacios o proyectos independientes. Sostenemos, así, que la sociabilidad que producen estas estrategias es conflictiva, efímera, espacialmente delimitada y afectiva. Tanto nuestra postura teórica como los hallazgos de nuestro trabajo de campo nos llevarán a concluir que las relaciones gestadas en estos microespacios –donde el conflicto es productivo, lo efímero predispone a la negociación y el afecto es cuidado– operan como un proceso imprescindible para la politización de las prácticas artísticas colaborativas en la ciudad neoliberal.
Prácticas sociales en el arte en la ciudad de Madrid: intervención con colectivos vulnerables
Authors: García Oliveros Elena
Published: January 2022

As of two cases in this study which were carried out in Madrid as social practices in art, community methodologies have been detailed as practiced in order to formalize collaborative creation proposed by each one. El Beso (The Kiss) (2018) and Cuentos que nunca cuentan (Tales that are never told) (2010) were carried out by the artist Toxic Lesbian with the participation of institutions such as Medialab-Prado and Intermediae, both of which are integrated in Matadero Madrid, Contemporary art creation center of the City Hall of Madrid. Both cases involved participation of the most directly concerned audiences because of the themes undertaken: migrant women in El Beso (The Kiss) and collectives of directly involved people in mental health in Cuentos que Nunca Cuentan (Tales that are never told). The proposals presupposed intervention in the public space of the city for their production and involved a wide representation of activists and elements of social or cultural institutions. This qualitative análisis of the processes and testimonies of the agents that participated seeks delving into the motivations of communities to become involved in this type of development, the role played by institutions or the inevitable politization of the proposals by the administrative structures that finance them.

A partir de dos casos, objetos de este estudio, y desarrollados en la ciudad de Madrid como prácticas sociales en el arte, se pormenoriza en sus metodologías comunitarias puestas en práctica para formalizar la creación colaborativa que cada uno propone. El Beso (2018) y Cuentos que nunca cuentan (2010) fueron llevados a cabo por la artista Toxic Lesbian con la participación de instituciones como Medialab-Prado e Intermediae, ambas integradas en Matadero Madrid, Centro de creación contemporánea del ayuntamiento. Los dos casos supusieron la participación de los públicos más directamente concernidos por las temáticas abordadas: mujeres migrantes en El Beso y colectivos en primera persona en salud mental para Cuentos que nunca cuentan. Las propuestas presuponían la intervención en el espacio público de la ciudad para su producción, e implicaron a una amplia representación de la sociedad civil a través de asociaciones, activistas y dispositivos institucionales sociales o culturales. Este análisis cualitativo de los procesos y testimonios de los agentes intervinientes persigue profundizar en las motivaciones de las comunidades para implicarse en estos desarrollos, en el papel de las instituciones o en la irremediable politización de las propuestas por parte de las estructuras administrativas que los financian.
