description: Con questo contributo intendiamo restituire in forma sintetica i principali risultati del progetto di ricerca di rilevante interesse nazionale (PRIN) “Territori post-metropolitani come forme urbane emergenti: le sfide della sostenibilità, abitabilità e governabilità”, di seguito abbreviato in “PRIN Postmetropoli”. Finanziato dal Ministero dell’Istruzione, dell’Università e della Ricerca (bando 2010-2011) il progetto ha visto coinvolte, col coordinamento del Politecnico di Milano, otto unità di ricerca afferenti ad altrettanti atenei italiani. La ricerca ha esplorato le principali aree urbane italiane analizzando in particolare quei processi di “regionalizzazione urbana” in cui città di diversa taglia, estensione e rango interagiscono e compartecipano alla produzione della condizione urbana contemporanea. Nel corso del triennio di attività (luglio 2013-giugno 2016), al fine di contribuire al dibattito disciplinare internazionale, si è cercato di indagare la specificità del territorio italiano rispetto alle concettualizzazioni dell’urbano offerte dalla letteratura internazionale. Sono stati quindi messi a fuoco sia i principali fenomeni e processi che ricalcano un modo di offrire abitabilità e urbanità tradizionalmente associato all’idea otto-novecentesca di città, sia quelli che stanno mettendo in tensione tali forme di riproduzione urbana. L’obiettivo ultimo è stato quello di tracciare nuovi possibili orientamenti progettuali e nuovi scenari di innovazione, nel campo delle politiche pubbliche e in particolare nell’agenda urbana nazionale e locale, per consentire ai territori post-metropolitani di rispondere efficacemente alle piccole e grandi sfide poste dai processi in corso. Questo contributo restituisce in modo sintetico quanto più ampiamente esposto e illustrato all’interno di due volumi pubblicati per collana “Il futuro delle città” edita da Guerini e Associati: Oltre la Metropoli (Balducci, Fedeli, Curci, 2017a) e Ripensare la questione urbana (Balducci, Fedeli, Curci, 2017b); tali volumi restituiscono l’esito collettaneo del lavoro e sono completati da una serie di pubblicazioni, prodotte dalle sedi locali, che raccolgono i contributi specifici delle diverse sedi al progetto di ricerca (si veda la bibliografia per i riferimenti ai diversi testi e il sito www.postmetropoli.it).

The political economy of televisual flow and industrial perception of audiences
Creators: name: Voorhees, Steven S.
Publisher: name: No Publisher Supplied
Year: 2020

description: Long before the popular rise of digital video recorders, streaming media services, and mobile devices, Raymond Williams (1975) introduced the concept of flow as the culturally defining characteristic of television. Over forty years later, Williams’ concept of televisual flow is more relevant than ever as television content and audiences have become diffused and fragmented across a multitude of digital networks, platforms, and devices. This study attempts to conduct a deep-dive into the television industry to build upon Williams’ original concept and learn what is at stake for contemporary audiences. Furthermore, it challenges the basic linear/non-linear framework by which televisual flow is typically defined today and attempts to replace it with the more specific concepts of universal and personalized flows. By analyzing trade publications and interviewing industry executives, this research adopts Herbert Schiller’s method of “listening in” to the industry in order to reveal the strategies and power structures guiding the programming, measuring, and regulating of televisual flow in the United States. Results portray television as an industry guided by self-preservation and an insatiable appetite for viewer data, strategically protecting legacy business models while inconspicuously transferring those same strategies onto new forms of flow in an attempt to extract even greater value from audiences.
La bioregione urbana nell’approccio territorialista

description: Gli attuali processi di urbanizzazione manifestano un pesante impatto sull’insediamento umano e sull’ambiente di vita in generale. Disgregazione sociale, socio-economica e delle comunità umane sono accompagnate dalla compromissione degli ecosistemi, la perdita di suolo fertile che interagiscono a loro volta con i cambiamenti climatici secondo una spirale di muto rafforzamento. Basandosi sull’approccio bio-regionalista –e in particolare sulla eredità dei “padri” del regionalismo- questo contributo espone i principali riferimenti per la definizione di “una utopia concreta” di carattere trasformativo per affrontare le problematiche indicate. In questo quadro il punto di riferimento principale è costituito dall’idea del territorio concepito come “bene comune” e sul recupero della relazione co-evolutiva fra insediamento umano e dotazioni ecosistemiche. Viene in particolare indicata la necessità di supportare un processo di costruzione e recupero “dal basso” di “coscienza di luogo” da parte degli abitanti, come elemento chiave per alimentare convivialità di vita ed uso sostenibile del patrimonio territoriale adeguato anche a generare economie locali e regionali auto-sostenibili. Tale “movimento” di progetto si basa in particolare sulla figura della “bioregione urbana” e sui suoi materiali costitutivi: conoscenza ed abilità contestuali, qualità degli ecosistemi e stabilità idro-geomorfologica, sistemi insediativi policentrici e riqualificazione/centralità dello spazio pubblico, economie locali auto-sostenibili, sistemi energetici locali misti, multifunzionalità delle aree agro-forestali e, ultimo ma non meno importante, la ridefinizione in termini partecipativi degli organismi locali della vita politico/amministrativa. Il contributo affronta dunque il tema del profilo “urbano” del mondo -destinato almeno apparentemente a configurarsi come un insieme di megacity- definendo un insieme di linee guida strategiche e di progetto per invertire l’attuale modello di sviluppo top-down e proporre una visione territoriale basata su un insieme di bioregioni cooperative caratterizzate da società locali e comunità eque ed inclusive.

description: L’interpretazione regionale dei processi insediativi costituisce un riferimento disciplinare fondamentale per la pianificazione urbana e territoriale a partire dal ventesimo secolo. Negli ultimi decenni, alla luce dei cambiamenti epocali nei processi di urbanizzazione regionale, ha permesso di definire lo sfondo concettuale di numerosi contributi analitico/interpretativi di indirizzo progettuale per la governance e la pianificazione dei sistemi urbani e regionali. Ciò appare tanto più rilevante nel momento in cui i processi globali di riorganizzazione dei fattori economici, le criticità sociali ed ambientali ad essi associate e la poliforme e acuta evoluzione del fenomeno urbano, richiedono la ricostituzione di plausibili orizzonti di senso dello sviluppo ma anche pathways socio-spaziali adeguati ad affrontare le sfide derivate da questi cambiamenti. Il contributo si inserisce in questo dibattito offrendo una survey argomentata dei principali riferimenti forniti in letteratura, e selezionando alcune direzioni di ricerca particolarmente fertili per il campo della pianificazione urbana e regionale. In particolare suggerisce un approccio regionale per l’interpretazione dei processi contemporanei di “urbanizzazione planetaria”, indicando il modello della città-regione, e in particolare la sua possibile declinazione nella forma della “bioregione urbana”, come framework per sviluppare linee strategiche progettuali finalizzate a una ridefinizione durevole, policentrica ed equa dell’insediamento umano.

description: A molecular model developed for resonances observed in medium light heavy-ion collisions is described. At high spins in 28Si+28Si (oblate-oblate system), a stable dinuclear configuration is found to be equator-equator touching one. The normal modes around the equilibrium are investigated. These modes are expected to be the origin of a large number of resonances observed. Furthermore, due to the axially asymmetric shape of the stable configuration of 28Si+28Si, the system rotates preferentially around the axis with the largest moment of inertia, which gives rise to wobbling motion ($K$-mixing). Energy spectra for the normal modes and for the extended model including the wobbling motion are given.

description: The goal of a therapy against autoimmune diseases would be to blunt immune responses against self antigens, without impairing systemic immunity. Our lab has been developing a nanoparticle-based therapy which consists of disease-relevant peptide-MHC complexes coated on iron-oxide nanoparticles (NPs). We have demonstrated that the therapeutic effects exerted by these NPs are associated with expansion of antigen-specific T-regulatory-type-1 (Tr1) cells and immuno-suppression of autoantigen-loaded antigen presenting cells (APCs) in an IL-10 and TGF-beta-dependent manner. We have established that suppression is disease- and organ-specific and effective in different autoimmune diseases (EAE and CIA) and genetic background (C57BL/6 and C57BL/10). We have found that NPs coated with epitopes released downstream from a disease-triggering insult can be as effective in suppressing disease as those coated with disease-inducing epitopes. EAE-relevant pMHC II-NPs were not only effective in suppressing inflammation but also in promoting re-myelination. Thus this therapy provides a negative feedback loop that serves to counter autoimmune disease progression.

description: Nella sezione Readings, la rivista pubblica alcuni testi di valore storico-documentario sul tema monografico di volta in volta affrontato. Per questo numero dedicato al tema delle migrazioni (e delle pratiche, anche alternative, di aiuto e di accoglienza), abbiamo scelto di ripubblicare alcune pagine del libro che Jane Addams (1860-1935) ha dedicato alla straordinaria esperienza della Hull-House, in un quartiere di Chicago popolato da stranieri provenienti da ogni parte del mondo. Il testo contiene alcune considerazioni riguardanti soprattutto i bambini – in particolare italiani – e le loro madri. Il contesto dell’immigrazione a Chicago era ovviamente molto diverso da quello attuale, ma l’esperienza di Addams costituisce ancora oggi una cornice di riferimento per i valori di umanità e ospitalità che sembrano proprio in questi giorni scemare nei paesi nei quali viviamo.

description: This contribution focuses on methodology and first results of a research aimed at clarify the way in which migrants are actors in the process of social production of territories by implementing socio-spatial practices that transform the contexts of origin/ arrival. Through the use of mobile methods, a multi-sited ethnography was conducted on the Egyptian community from Kafr Kela al-Bab (Nile Delta) towards Ostia (Rome), with the aim of shed light on the rurban evolution of the Nile Delta mesopolis and promotes, within the framework of urban policies, the translocal approach, considering mobility and permanence as two synergistic categories for territorial development.

Mutamenti spaziali come effetto di mutazioni sociali? Questioni aperte sui flussi migratori nei territori dell’agricoltura di qualità in Sicilia
Creators: name: Todaro, Vincenzo
Publisher: name: Contesti. Città, territori, progetti
Year: 2018

description: The official statistics on the movements of the immigrant population of the last 20 years in Sicily show a significant increase in foreign presences. Movements go beyond the seasonal dimension and are concentrated in non-urban areas with a greater agricultural vocation, where there are also high levels of economic innovation (Trapani and Ragusa). It is often a phenomenon with paradoxical outlines, considering that the economic results of quality agriculture are counterbalanced by the conditions in which immigrants live and work, being denied the right to the city and citizenship. Therefore, there is a significant interde- pendence between agricultural development and foreign presences that this paper intends to deepen by analyzing the spatial consequences of migration and the weakness of local policies.

description: China has achieved significant milestones in a very limited amount of time in terms of military capabilities, platforms, systems, and doctrine. While it is uncertain whether or not China can effectively be successful in the implementation of its A2/AD strategy against the United States, its eventual success may well reside in its capability to sustain an ever-increasing military budget when faced with other financial obligations. The United States, on the other hand, would likely prevail during a military encounter today given its superior firepower, its experience, and its capacity of innovation, but those trends are threatened by an ominous fiscal reality at home that may endanger its prospects to be the dominant power in the Asia Pacific region for the upcoming decades. The United States will need to settle its issues with sequestration or otherwise its strategy of forward presence in the region will not be sustainable.

description: Despite its historical and cultural values and its central position, the old town center of the city of Sassari (Sardinia, Italy) should be considered as a deprived urban area. In fact, the neighborhood is affected by the presence of a multiple contribut- ing factors which tend to combine with others to create a vicious cycle of social/spatial segregation: physical decay, inade- quate urban services, urban poverty, depopulation, many people - mainly immigrants - that experience housing issues, and the presence of a significant amount of abandoned buildings and spaces. The paper illustrates the results of a research project aiming at defining an innovative Plan for the old town center of the city of Sassari. The Plan mainly focuses on those issues that significantly foster this vicious cycle of marginalization and that, at the same time, could be addressed through planning and design: among these, the presence of a significant amount of abandoned buildings and spaces is the most relevant problem. The size of this unused building stock and the number of ne- glected extra-small spaces is rapidly increasing. A real and long-lasting solution is needed to reverse this trend. The Plan, and in particular its guidelines for designing policies and projects for social and collaborative housing, will significantly contribute to this purpose.

description: Abstract Background The introduction of new health professional roles, such as that of the nurse practitioner and pharmacist prescriber in primary health care can lead to changes in health service delivery. Consumers, having used these roles, often report high satisfaction. However, there is limited knowledge of how these individuals position nurse practitioner and pharmacist prescriber roles within existing practice structures. Methods Semi-structured interviews were conducted with 21 individuals receiving services from these practitioners in New Zealand primary health care. Interviews were recorded and transcribed verbatim for thematic analysis. Results Participant views reflect established practice hierarchies, placing advanced practitioners ‘below’ general practitioners. Participants are unable to articulate what it was about these practitioners that meant they operated at lower tiers and often considered practitioners to act as ‘their doctor’. They also highlight structural barriers impairing the ability of these providers to operate within their full scope of practice. Conclusions While seeing value in the services they receive, consumers are often unable to position nurse practitioner and pharmacist prescriber roles within health system contexts or to articulate how they value their practitioner’s skills. Embedded structural barriers may be more visible to consumers than their interactions with the health system suggest. This may influence peoples’ ability to receive intended or optimal health services. Consumer ‘health professional literacy’ around the functions of distinct health practitioners should be supported so that they may make informed service provision choices.
Effects of Transcranial Direct-Current Stimulation on Motor Learning in the Developing Brain

description: Transcranial direct-current stimulation (tDCS) is a form of non-invasive brain stimulation applied in both healthy and clinical populations. Application of weak current induces electric fields at the neuronal level, and may lead to behavioral effects such as enhanced motor learning when paired with training. Nearly all investigations to date have been completed in the adult brain, and fundamental studies are lacking in pediatrics, yet are required to advance and optimize tDCS application in this population. Additionally, given the ability of tDCS to enhance motor learning, translation to complex motor skill acquisition is necessary to define the full potential of tDCS. Here we investigated the effects of tDCS on motor learning in healthy children, with subsequent probing of neurophysiological changes underlying these behavioral changes using transcranial magnetic stimulation. Next, we compared tDCS-induced electric fields in the child, adolescent, and adult brain, using computational current modeling. Given the therapeutic potential of tDCS in pediatrics, we examined the safety and feasibility of tDCS application in childhood stroke. Finally, we examined the effects of tDCS on complex motor skill acquisition, including laparoscopic surgical and neurosurgical skills in medical trainees. Our findings suggest that tDCS can safely enhance motor learning in healthy children and young adults. Neurophysiological mechanisms underlying these changes appear to be variable. Current modeling suggests that children are exposed to substantially stronger electric fields compared to adults, possibly contributing to the complex neurophysiological changes seen with tDCS application in children. Despite inducing stronger electric fields, application of tDCS appears to be safe in children and adolescents. tDCS-enhanced motor learning may not be restricted to basic motor skills, but complex laparoscopic surgical skills, and neurosurgical tumor resection skills may be sensitive to enhancement as well. In summary, our findings suggest that tDCS application is safe in the developing brain, and capable of producing robust behavioral changes. These findings support the translation of tDCS to pediatric therapeutic investigations. Neurophysiological mechanisms of these changes require further investigation. Establishing the ability of tDCS to enhance surgical skill acquisition may counteract the current short-comings of surgical training, revolutionizing the field of medical education.
The effect of hyperfine interactions on ultracold molecular collisions: NH(^3Sigma^-) with Mg(^1S) in magnetic fields

description: We investigate the effect of hyperfine interactions on ultracold molecular collisions in magnetic fields, using ^{24}Mg(^1S) + ^{14}NH(^3Sigma^-) as a prototype system. We explore the energy and magnetic field dependence of the cross sections, comparing the results with previous calculations that neglected hyperfine interactions (Phys. Rev. Lett. 103, 183201 (2009)). The main effect of hyperfine interactions for spin relaxation cross sections is that the kinetic energy release of the dominant outgoing channels does not reduce to zero at low fields. This results in reduced centrifugal suppression on the cross sections and increased inelastic cross sections at low energy and low field. We also analyze state-to-state cross sections, for various initial states, and show that hyperfine interactions introduce additional mechanisms for spin relaxation. In particular, there are hyperfine-mediated collisions to outgoing channels that are not centrifugally suppressed. However, for Mg+NH these unsuppressed channels make only small contributions to the total cross sections. We consider the implications of our results for sympathetic cooling of NH by Mg and conclude that the ratio of elastic to inelastic cross sections remains high enough for sympathetic cooling to proceed.
description: Version 2 contains an improved and simplified discussion of the state-to-state cross sections. The abstract and general conclusions are unchanged

description: Inelastic interactions of nuclei accelerated to a momentum of 4.5 GeV/$c$ per projectile nucleon with photoemulsion nuclei have been investigated. The main features of these interactions - mean ranges of $^6$Li nuclei, mean multiplicities of secondaries, the isotopic composition of fragments, fragmentation channels, and the mean transverse momenta of projectile fragments - have been measured. The probability of the charge-exchange reaction featuring lithium nuclei has been determined. The results obtained for the $^6$Li nucleus have been compared with data for other nuclei. The observed features of $^6$Li interactions with other nuclei indicate that the $^6$Li structure in the form of the loosely bound system consisting of an $α$-particle and a deuteron cluster clearly manifests itself in these interactions. Events resulting in the coherent dissociation of $^6$Li nuclei into $^4$He+$d$, $^3$He+$t$, and $t+d+p$ and involving low-lying excitations of $^6$Li have been observed.

description: Town planners and social scientists have an intellectual duty to study the emergency sites crossed by a transversal human- itarian crisis. Extreme situations are a unique opportunity to observe the phenomena under construction. In the following pages there is an attempt to answer, which arises from a particular occasion that has allowed to address on the ground issues that have long been under discussion among researchers. The double challenge of the crisis and the tools to face it was in fact addressed on the island of Lampedusa during a workshop organized by the Cycle d’Urbanisme of the École Urbaine Sciences- Po of Paris in May 2016. The observation of the territory allowed to face on the spot broadly global issues, such as the impact of migratory flows in relation to supporting the economy, and the development of the territory in relation to the preservation of the landscape. The report that came out was discussed at an international conference, also in Lampedusa, which saw the mayors of some shelter cities reunited.

Year: 2016
Subjects: subject: Environmental Sciences
subject: climate change

description: Aerosols drive significant radiative forcing and affect Arctic climate. Despite the importance of these aerosols in Arctic climate change, there are some key uncertainties in the estimation of their effects and sources. Size-segregated aerosol, SO2 and precipitation samples were collected on board the Canadian Coast Guard Ship Amundsen in the Arctic during July 2014, to utilize the isotopic composition of sulfate to address the contribution of anthropogenic, biogenic and sea salt sources in formation/growth of aerosol. More than 63% of the average sulfate concentration in the fine aerosols (<0.49 μm) was from biogenic sources. For most samples, δ34S values for SO2 and fine aerosols were similar, suggesting gas-to-particle conversion. δ34S apportionment for precipitation samples suggested a relatively low contribution of the biogenic sulfate source (14±8%) and high contribution of sea salt (82±10%). Also, the size distribution of ice nucleation particles (INPs) in the immersion mode was determined for solid particles smaller than 0.45 μm and soluble aerosol in the size range of 0.49-7.2 μm. Large particles (3.0-7.2 μm), were more efficient INPs. In addition, vertical distributions of atmospheric dimethyl sulfide were sampled aboard the research aircraft Polar 6 near Lancaster Sound in July 2014 and on pan-Arctic flights in April 2015. Larger mean DMS mixing ratios were present during April 2015 (campaign-mean of 116±8 pptv) than July 2014 (campaign-mean of 20±6 pptv). A strong decrease was observed in DMS mixing ratios with altitude in July 2014. In contrast, DMS mixing ratios sampled in April 2015 exhibited a relatively more uniform campaign-mean vertical profile and increased with altitude on some flights. These results highlight the role of open water below the flight as the source of DMS during July 2014, and the influence of long-range transport of DMS from further afield in the Arctic during April 2015. In general, the high biogenic fraction of sulfate fine aerosol and relatively high DMS mixing ratios emphasize the role of marine organisms in the formation of fine particles above the Arctic Ocean during July. More investigations are required to find the role of biogenic aerosols in formation of INPs in the Arctic atmosphere.
The remedy of substantive consolidation under the Companies' Creditors Arrangement Act : a closer examination of domestic and cross-border issues
Creators: name: Sevenoaks, Helen Mary Emma
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a study on the remedy of substantive consolidation under Canada‟s primary restructuring statute, the Companies’ Creditors Arrangement Act (“CCAA”). The objectives of the research are (i) to gain a deeper understanding of how substantive consolidation has evolved under the CCAA, (ii) to investigate whether the current legal landscape provides the most appropriate framework for dealing with the key issues relating to substantive consolidation in both the domestic and cross-border context, and (iii) consider how, if necessary, the position could be improved. The key issues that are the focus of this study are: (a) the factors supporting substantive consolidation, (b) the effect of substantive consolidation and (c) multiple issues relating to the application for an order such as persons permitted to apply, timing on an application, inclusion of a solvent group member and notice. The doctrinal analysis of the existing jurisprudence suggests there is a failure to carefully consider these key issues in depth. The judicial dialogue solely focuses on the factors supporting consolidation in the domestic context. There is little, if any, guidance on the issues that stem from an application for substantive consolidation or the various effects substantive consolidation can have on creditors‟ rights. Further, the use of substantive consolidation under the CCAA cross-border framework has yet to be considered at all. Therefore, this study looks towards the recent work of the United Nations Commission on International Trade Law Working Group V (Insolvency Law) on substantive consolidation in order to propose an array of policy options for the use of the remedy under the CCAA. In doing so, the study takes into account the scope of the CCAA, the balance between the need for flexibility and the demand for certainty in CCAA proceedings, what is desirable in practice and the nature of cross-border restructuring proceedings.

description: We derive the semiclassical Kirzhnits expansion of the D-dimensional one-particle density matrix up to the second order in $\hbar$. We focus on the two-dimensional (2D) case and show that all the gradient corrections both to the 2D one-particle density and to the kinetic energy density vanish. However, the 2D Kirzhnits expansion satisfies the consistency criterion of Gross and Proetto [J. Chem. Theory Comput. 5, 844 (2009)] for the functional derivatives of the density and the noninteracting kinetic energy with respect to the Kohn-Sham potential. Finally we show that the gradient correction to the exchange energy diverges in agreement with the previous linear-response study.

description: The Protection System for Asylum Seekers and Refugees (SPRAR) is the network of local municipalities and institutions aiming integrated reception for forced migrants in Italy. The study focuses on the key role of “small municipalities” in Italy (Municipalities less populated than 5,000 residents) within such network, basing the analyses on the SPRAR key features. The role of the small municipalities is growing over years and is becoming more strategic and relevant under a quantitative perspective as well as in terms of impact and enhancement on asylum seekers and refugees in the local involved territories. Indeed, small municipalities represent 28.6% of all the project holders (Municipalities, Provinces, or other institutions) in Italy, value increasing up to 51.4% if considering all the municipalities involved in the SPRAR: out of 1,017 Italian municipalities involved, 523 might be considered as small. Thanks to the forced migrants hosting, in such small territories a variety of welfare services, productive activities, and Institutions networks has been reactivated, fostered or grown. Hence, the study analyses in depth the main actions of the integrated hosting run by the SPRAR in such territories, interpreting the local dimension and framework of this kind of System as the starting point of the “Italian route” towards integration.

Migrancy. Movimenti di popolazione e costruzione dei luoghi

description: Mobility and migrations characterize the transformations of contemporary cities and societies. On the one hand the mobility of things and goods, knowledge and information, of natural and artificial resources, images and ideas, cultural models and life-styles. On the other, the increasingly complex reality of population movements, at local, global, regional or transnational levels, driven by economic needs or the dangers of war, climatic change or the wish for a better life. Migrants who move from the countryside to the cities, and sometimes the opposite, from the south to the north and viceversa, from the mainland to the coast, mountains to plains, from centres to suburbs or from the suburbs toward new centres. Adding up all of these possible relocations, research has estimated that population movements have involved over the past few years more than a billion people. Scientific literature and on-field research have attempted to define, foresee and govern the phenomenon, also through new definitions and analytic categories, in order to include all its various aspects: migrancy, dislocation, displacement, expulsion, unsettlement. This number of Contesti proposes to discuss the spatial effects of population movements within the larger theme of mobility in general, and the consequences on the design of urban and regional policies. Migrancy and placemaking, population movements and spatial consequences, are considered.

description: My dissertation consists of three studies that investigate gender diversity, board interlocks, and environmental performance. In the first study, I investigate whether gender diversity is related to firms’ environmental performance. Built on resource dependence theory, I argue that compared to male directors, female directors provide different human resources. Thus, gender diversity in the boardroom leads to better environmental performance by providing a greater pool of resources. Using a sample of S&P 1500 firms in the US between 2009 and 2012, I find a positive relationship between gender diversity and environmental performance using regressions. This study provides a recent snapshot of gender diversity practice and firms’ environmental performance after Sarbanes-Oxley and the 2007-2008 financial crisis, using a much larger sample size than previous research. In the second study, I delve deeper into the relational dimension of corporate governance, specifically the link between board interlocks and environmental performance. Social network theory argues that an organization’s outcome is affected by its position in the network and board interlocks create channels for sharing of information between firms. Using the same sample as study No. 1, I find an interesting phenomenon that board interlocks serve as channels of information diffusion that result in good environmental performance, but poor environmental performing firms do not share information as much. This study provides empirical evidence that board interlocks serve an information filtering function depending on directors’ values alignment. In my last study, I test the link between board interlocks, the interlocking directors’ sustainability-related human and social capital, and environmental performance. I combine resource dependence theory and social network theory, which suggest that board interlocks serve as effective channels of sharing information and the interlocking directors’ experiences play a role in the process of diffusion. Using regressions, I find that both interlocking directors’ sustainability-related human and social capital contribute to environmental performance positively. My work responds to numerous research studies that call for empirical evidence of the relationship among board interlocks, interlocking directors’ characteristics, and organizational outcomes.
The Making of Democratic Streets

description: Streets are an important part of the landscape of everyday life. Much social life and learning occur along streets: streets have meaning for people, invite access for all, encourage use and participation, are loved, and are well cared for by their users. In this paper the story of life and street culture is reconsidered, and in the concluding part an alternative perspective is introduced, that of "democratic streets", which provides a broader and more holistic view of street culture.

description: In the process of barbarisation that destroys every existing social link and opens a desolating post-human scenario, the alternative, albeit difficult, seems to be that of a re-discovery and revalorization of horizontal relationships and of the growth of communities linked to the territory. The article tells a unique ‘story of urban resistance’ which shows, and not only symbolically, how some forms of economic liberalism can be stopped when the members of a neighbourhood community rise up (in this case helped, we could say, ‘by a friendly nature’) in opposition to an act of overbearing arrogance organized against the city and its inhabitants.

description: Like taking a walk with the reader, in the article the author tries to drive the attention to objects arranged in space. Using some examples, the article reflects on their meanings and values, showing how rich and articulate a street may be. In particular, the author focuses on the clothes hanging outside, as a means of communication through which the gap between public and private is reduced.

description: Рассматривается разработка конструкции трехслойного шарового резервуара, а также методика построения ее в программном комплексе SCAD. Разработка материала достаточно жесткого и удовлетворяющего требованию прочности и устойчивости к воздействию различных нагрузок является весьма сложным и трудоемким процессом. Необходимость одновременного удовлетворения ряду требований приводит к идее разработки трехслойных конструкций, в которых заполнитель выполняет одну или лучше несколько функций. Подробно описана методика построения и приведена конструкция трехслойного шарового резервуара.
Hydrodynamic Vortices and their Gravity Duals

description: In this talk we review analytical and numerical studies of hydrodynamic vortices in conformal fluids and their gravity duals. We present two conclusions. First, (3+1)-dimensional turbulence is within the range of validity of the AdS/hydrodynamics correspondence. Second, the local equilibrium of the fluid is equivalent to the ultralocality of the holographic correspondence, in the sense that the bulk data at a given point is determined, to any given precision, by the boundary data at a single point together with a fixed number of derivatives. With this criterion we see that the cores of hot and slow (3+1)-dimensional conformal generalizations of Burgers vortices are everywhere in local equilibrium and their gravity duals are thus easily found. On the other hand local equilibrium breaks down in the core of singular (2+1)-dimensional vortices, but the holographic correspondence with Einstein gravity may be used to define the boundary field theory in the region in which the hydrodynamic description fails.

description: Games offer an innovative new method for assessing cognitive ability. We hypothesize that game-based assessments correlate with traditional assessments of cognitive ability, and exhibit smaller racial differences in performance. We integrate perceived stereotype threat, test-taking motivation, and anxiety to explain how games might reduce racial differences in performance. In a mock selection situation, participants applied for a job by completing game-based and traditional assessments. Results showed that game-based assessments were positively correlated with traditional assessments (r = .35-.50), and exhibited smaller racial differences than one of the traditional assessments. We found that perceived stereotype threat mediated the race-performance relationship and that game-based assessments were associated with higher test-taking motivation and lower anxiety than some of the traditional assessments; however, our proposed mechanisms did not account for the reduction in racial differences on the game-based assessments. We recommend further investigation into the validity of game-based assessments for selection.

description: Основной причиной аварий длительно эксплуатируемых в Республике Беларусь магистральных трубопроводов является отказ кольцевых сварных соединений вследствие развития в них уже имеющихся и зарождения новых дефектов, приводящих к разрыву трубопровода или образованию коррозионного свища. Восстановления вязкопластичных свойств металла сварных соединений возможно за счет проведения ремонтных работ методом термической обработки. В то же время отсутствуют исследования о влиянии данного метода на коррозионную стойкость сварных соединений. В статье приведены данные о влиянии термической обработки на коррозионную стойкость участков кольцевого сварного соединения магистральных трубопроводов, претерпевших длительную эксплуатацию.
