O hip hop é um movimento político, social e cultural presente nas periferias do Brasil desde 1980. O hip hop vem se desenvolvendo ao longo dos anos, criando espaço, ganhando visibilidade e ampliando o seu público, principalmente entre os segmentos das juventudes urbanas. O presente trabalho teve como objetivo principal investigar o Movimento Enraizados, uma organização hip hop da Baixada Fluminense, que articula e interage com parceiros em diversos estados e alguns países. Nesse contexto, o estudo selecionou três questões como eixos para a análise. Como foi criada a Rede Enraizados e quais são suas principais características? Como o Movimento Enraizados produz territórios existenciais na Baixada Fluminense? Como o Movimento Enraizados utiliza a linguagem radiofônica para expressar suas ações? Para a análise das questões levantadas, a pesquisa utilizou o referencial teórico de Antonio Negri e Deleuze & Guattari, costurando os conceitos de comum, multidão, rádios livres, ritornelos, territórios. A sede do Movimento Enraizados, em Morro Agudo / Nova Iguaçu, é o centro Rede Enraizados e responsável pela dinamização das informações em seus diversos canais de comunicação. Ao disparar seus projetos e iniciativas na construção de uma rede intercontinental de apoio-mútuo, o Movimento Enraizados desterritorializa sentidos e práticas da Baixada Fluminense. Essa desterritorialização produz uma mensagem potente de militância cultural para jovens e fortalece redes para a construção de novas resistências biopolíticas nesses territórios.

After researching the coupling relationship among choosing raw material, stone technology, environmental change and Huaman evolution stage of archeological sites in different sediment in north China, the author thinks that: The human behavior is different in loessic region between glacial and interglacial ages. In Human evolution procession, Human erectus and early Human sapiens may co-exist in north China before L2, but after L2Human erectus disappear, and the stone technology of early Human sapiens become more progression. After comparing the age and environment, geology context, stone technology and using fire between them, we may make a preliminary conclusion that the environmental change during L2 maybe the outer reason and different capability of adaptation between Human erectus and early Human Sapiensis is the inner reason of Human erectus becoming disappear. The environmental change in last glacial climax and deglacial may result in new crowd and new culture entering into North China, which break the culture tradition which exist since early stage of palaeolithic. And play an important role from palaeolithic stage into neolithic stage. So unstable envirnmental change play an important role in Human evolution procession, and different scale environment change have different effect, large scale environmental change make small effect, but millenary scale even more short scale environmental change may bear more important role, some times it can transfer the evolution direction.

The purpose of this paper is to demonstrate the potential of the EXODUS evacuation model in building environments. The latest PC/workstation version of EXODUS is described and is also applied to a large hypothetical supermarket/restaurant complex measuring 50 m x 40 m. A range of scenarios is presented where population characteristics (such as size, individual travel speeds, and individual response times), and enclosure configuration characteristics (such as number of exits, size of exits, and opening times of exits) are varied. The results demonstrate a wide range of occupant behavior including overtaking, queuing, redirection, and conflict avoidance. Evacuation performance is measured by a number of model predicted parameters including individual exit flow rates, overall evacuation flow rates, total evacuation time, average evacuation time per occupant, average travel distance, and average wait time. The simulations highlight the profound impact that variations in individual travel speeds and occupant response times have in determining the overall evacuation performance. 1.

In Spain, during the recent housing bubble, purchasing a home seemed the most advantageous strategy to access housing, and there was a wide social consensus about the unavoidability of mortgage indebtedness. However, such consensus has been challenged by the financial and real-estate crisis. The victims of home repossessions have been affected by the transgression of several principles, such as the fair compensation for effort and sacrifice, the prioritisation of basic needs over financial commitments, the possibility of a second chance for over-indebted people, or the State's responsibility to guarantee its citizens' livelihood. Such principles may be understood as part of a moral economy, and their transgression has resulted in the emergence of a social movement, the Plataforma de Afectados por la Hipoteca (PAH), that is questioning the legitimacy of mortgage debts. The article reflects on the extent to which the perception of over-indebtedness and evictions as unfair situations can have an effect on the reproduction of the political-economic system, insofar the latter is perceived as able or unable to repair injustice.

Hillsborough: The Truth was first published in 1999 to universal acclaim. Established as the definitive, unique account of the disaster, in which 96 men, women and children died, hundreds were injured and thousands traumatised, it details the appalling treatment endured by the bereaved and survivors in the immediate aftermath and the inhumanity of the identification process. It reveals the inadequacies of the police investigations, official inquiries and inquests, uncovering the systematic review and alteration of South Yorkshire police statements conducted with the approval of police investigators and Lord Justice Taylor’s inquiry. It examines in depth the subsequent private prosecution and trial of two senior police officers in 2000. Using verbatim accounts, Scraton's detailed analysis demonstrates the inadequacy of legal processes and the remarkable breadth of judicial discretion, undermining and inhibiting such cases.

Powerful, disturbing and harrowing, Hillsborough: The Truth exposes the institutional complacency that made a tragedy on this scale inevitable. It shows the law’s failure to provide appropriate means of access, disclosure and redress for those facing the consequences of institutional neglect and personal negligence. And it tells how ordinary people suffer when those in authority sacrifice truth and accountability to protect their reputations. In this new edition Scraton reflects critically on two decades of policy and legal reform including crowd safety and inquest procedure and on the continuing struggles of the bereaved and survivors who have campaigned relentlessly for truth, acknowledgment and justice.

ANPO (A Non-predefined Outcome) is an an art-making methodology that employs structuralist theory of language (Saussure, Lacan, Foucault) combined with Hegel’s dialectic and the theory of creation of space by Lefebvre to generate spaces of dialogue and conversation between community members and different stakeholders. These theories of language are used to find artistic ways of representing a topic that community members have previously chosen. The topic is approached in a way that allows a visual, aural, performative and gustative form. To achieve this, the methodology is split in four main steps: step 1 ‘This is not a chair’, Step 2 ‘The topic’, Step 3 ‘ Vis-á-vis-á-vis’ and step 4. ‘Dialectical representation’ where the defined topic is used to generate artistic representations.The step 1 is a warm up exercise informed by the Rene Magritte painting ‘This is not a Pipe’. This exercise aims to help the participants to see an object as something else than an object but as a consequence of social implications. Step 2, participants choose a random topic and vote for it. The artist/facilitator does not predetermine the topic, participants are the one who propose it and choose it. Step 3, will be analysed in this publication and finally step 4, the broken down topic is taken to be represented and analysed in different ways.

We develop and test a dual pathway model of effervescence - the intensely positive experience of being in a crowd. The model proposes that positive feelings arise when those attending a mass event see each other as sharing a common social identity. This sense of shared identity predicts (a) crowd participants’ ability to enact their valued collective identity, and (b) the intimacy of social relations between crowd members. In turn, both of these are theorized to predict crowd members’ positivity of experience. These ideas are tested using survey data from pilgrims (n = 416) attending the Magh Mela - a month-long Hindu pilgrimage festival in north India. The findings provide clear support for the model.

In April 1989, ninety-six men, women and children, supporters of Liverpool Football Club, died in a severe crush at an FA Cup semi-final at Hillsborough Stadium, Sheffield. Hundreds were injured and thousands traumatised. Within hours, the causes and circumstances of the disaster were contested. While a judicial inquiry found serious institutional failures in the policing and management of the capacity crowd, no criminal prosecutions resulted, and the inquests returned ‘accidental death’ verdicts. Immediately, the authorities claimed that drunken, violent fans had caused the fatal crush. Denied legitimacy, survivors’ accounts revealed a different story criticising the parlous state of the stadium, inadequate stewarding, negligent policing, failures in the emergency response and flawed processes of inquiry and investigation. Reflecting on two decades of research and contemporaneous interviews with bereaved families and survivors, this article contrasts the official discourse with those alternative accounts – the ‘view from below’. It demonstrates the influence of powerful institutional interests on the inquiries and investigations. It maps the breakthrough to full documentary disclosure following the appointment of the Hillsborough Independent Panel, its research and key findings published in September 2012. The campaigns by families and survivors were vindicated and the fans, including those who died, were exonerated. The process is discussed as an alternative method for liberating truth, securing acknowledgement and pursuing justice.

The principle feature in the evolution of the internet has been its ever growing reach to include old and young, rich and poor. The internet’s ever encroaching presence has transported it from our desktop to our pocket and into our glasses. This is illustrated in the Internet Society Questionnaire on Multistakeholder Governance, which found the main factors affecting change in the Internet governance landscape were more users online from more countries and the influence of the internet over daily life. The omnipresence of the internet is self- perpetuating; its usefulness grows with every new user and every new piece of data uploaded. The advent of social media and the creation of a virtual presence for each of us, even when we are not physically present or ‘logged on’, means we are fast approaching the point where we are all connected, to everyone else, all the time. We have moved far beyond the point where governments can claim to represent our views which evolve constantly rather than being measured in electoral cycles.
The shift, which has seen citizens as creators of content rather than consumers of it, has undermined the centralist view of democracy and created an environment of wiki democracy or crowd sourced democracy. This is at the heart of what is generally known as Web 2.0, and widely considered to be a positive, democratising force. However, we argue, there are worrying elements here too. Government does not always deliver on the promise of the networked society as it involves citizens and others in the process of government. Also a number of key internet companies have emerged as powerful intermediaries harnessing the efforts of the many, and re- using and re-selling the products and data of content providers in the Web 2.0 environment. A discourse about openness and transparency has been offered as a democratising rationale but much of this masks an uneven relationship where the value of online activity flows not to the creators of content but to those who own the channels of communication and the metadata that they produce.
In this context the state is just one stakeholder in the mix of influencers and opinion formers impacting on our behaviours, and indeed our ideas of what is public. The question of what it means to create or own something, and how all these new relationships to be ordered and governed are subject to fundamental change. While government can often appear slow, unwieldy and even irrelevant in much of this context, there remains a need for some sort of political control to deal with the challenges that technology creates but cannot by itself control. In order for the internet to continue to evolve successfully both technically and socially it is critical that the multistakeholder nature of internet governance be understood and acknowledged, and perhaps to an extent, re- balanced. Stakeholders can no longer be classified in the broad headings of government, private sector and civil society, and their roles seen as some sort of benign and open co-production. Each user of the internet has a stake in its efficacy and each by their presence and participation is contributing to the experience, positive or negative of other users as well as to the commercial success or otherwise of various online service providers. However stakeholders have neither an equal role nor an equal share. The unequal relationship between the providers of content and those who simple package up and transmit that content - while harvesting the valuable data thus produced - needs to be addressed. Arguably this suggests a role for government that involves it moving beyond simply celebrating and facilitating the on- going technological revolution. This paper reviews the shifting landscape of stakeholders and their contribution to the efficacy of the internet. It will look to critically evaluate the primacy of the individual as the key stakeholder and their supposed developing empowerment within the ever growing sea of data. It also looks at the role of individuals in wider governance roles. Governments in a number of jurisdictions have sought to engage, consult or empower citizens through technology but in general these attempts have had little appeal. Citizens have been too busy engaging, consulting and empowering each other to pay much attention to what their governments are up to. George Orwell’s view of the future has not come to pass; in fact the internet has insured the opposite scenario has come to pass. There is no big brother but we are all looking over each other’s shoulder all the time, while at the same time a number of big corporations are capturing and selling all this collective endeavour back to us.

We analyze a set of 760 475 observations of 333 026 unique main-belt objects obtained by the Pan-STARRS1(PS1) survey telescope between 2012 May 20 and 2013 November 9, a period during which PS1 discoveredtwo main-belt comets, P/2012 T1 (PANSTARRS) and P/2013 R3 (Catalina-PANSTARRS). PS1 cometdetection procedures currently consist of the comparison of the point spread functions (PSFs) of movingobjects to those of reference stars, and the flagging of objects that show anomalously large radial PSFwidths for human evaluation and possible observational follow-up. Based on the number of missed discoveryopportunities among comets discovered by other observers, we estimate an upper limit comet discoveryefficiency rate of 70% for PS1. Additional analyses that could improve comet discovery yields infuture surveys include linear PSF analysis, modeling of trailed stellar PSFs for comparison to trailed movingobject PSFs, searches for azimuthally localized activity, comparison of point-source-optimized photometryto extended-source-optimized photometry, searches for photometric excesses in objects withknown absolute magnitudes, and crowd-sourcing. Analysis of the discovery statistics of the PS1 surveyindicates an expected fraction of 59 MBCs per 106 outer main-belt asteroids (corresponding to a totalexpected population of 140 MBCs among the outer main-belt asteroid population with absolute magnitudesof 12 < HV < 19:5), and a 95% confidence upper limit of 96 MBCs per 106 outer main-belt asteroids(corresponding to a total of 230 MBCs), assuming a detection efficiency of 50%. We note howeverthat significantly more sensitive future surveys (particularly those utilizing larger aperture telescopes)could detect many more MBCs than estimated here. Examination of the orbital element distribution ofall known MBCs reveals an excess of high eccentricities (0:1 < e < 0:3) relative to the background asteroidpopulation. Theoretical calculations show that, given these eccentricities, the sublimation rate for atypical MBC is orders of magnitude larger at perihelion than at aphelion, providing a plausible physicalexplanation for the observed behavior of MBCs peaking in observed activity strength near perihelion.These results indicate that the overall rate of mantle growth should be slow, consistent with observationalevidence that MBC activity can be sustained over multiple orbit passages.

The present study investigates how attendees at national celebratory crowd events-specifically St. Patrick's Day parades-understand the role of such events in representing and uniting the national community. We conducted semi-structured interviews with people who attended St. Patrick's Day parades in either Dublin or Belfast. In year 1, full-length interviews were conducted before and after the events (N=17), and in years 1 and 2, shorter interviews were conducted during the events (year 1 N=170; year 2 N=142). Interview data were analysed using thematic analysis, allowing the identification of three broad themes. Participants reported that (i) the events extend the boundary of the national group, using participation to define who counts as Irish; (ii) the events strategically represent the nature of the national group, maximising positive images and managing stereotypical representations; and (iii) symbolism serves to unify the group but can also disrupt already fragile unity and so must be managed. Overall, this points to a strategic identity dimension to these crowd events. We discuss the implications of these findings for future research in terms of the role of large-scale celebratory events in the strategic representation of everyday social identities.

In 1748, Bartholomew Mosse, a curious combination of surgeon, obstetrician and entertainment impresario, established a pleasure garden on the northern fringes of Dublin. Ostensibly designed to fund the construction of a maternity hospital to be located adjacently, Mosse’s New Pleasure Gardens became one of the premier leisure resorts in Dublin. This was to have a profound effect on the city’s urban form. Within a few years the gardens became an epicentre of speculative development as the upper classes jostled to build their houses in the vicinity. Meanwhile, the creation nearby of Sackville Mall, a wide and generous strolling ground, established a whole section of the city dedicated to haute spectacle, display and leisure. Like other pleasure gardens in the British Isles, Mosse’s venture introduced new, commodified forms of entertainment. In the colonial context of eighteenth-century Ireland, however, ‘a land only recently won and insecurely held’ (Foster, 1988) by the Protestant Anglo-Irish settler class, the production of culture and spectacle was perhaps more significant than elsewhere. Indeed, the form of Mosse’s gardens echoed the private city gardens of a key figure in the Anglo-Irish aristocracy, while the hospital itself was constructed in a style of a Palladian country house, symbol of colonial presence in the countryside. However, like other pleasure gardens, the mix of music and alcohol, the heterogeneous crowd culled from across social and gender boundaries, and a landscape punctuated with secluded corners, meant that it also acquired a dubious reputation as a haunt of louche and illicit behaviours. The curious juxtaposition between a maternity hospital and pleasure garden, therefore, begins to assume other, hitherto hidden complexities. These are borne out by a closer examination of the architecture of the hospital, the shape of its landscape and the records of its patrons and patients.

Introduction: Fewer than 50% of adults and 40% of youth meet US CDC guidelines for physical activity (PA) with the built environment (BE) a culprit for limited PA. A challenge in evaluating policy and BE change is the forethought to capture a priori PA behaviors and the ability to eliminate bias in post-change environments. The present objective was to analyze existing public data feeds to quantify effectiveness of BE interventions. The Archive of Many Outdoor Scenes (AMOS) has collected 135 million images of outdoor environments from 12,000 webcams since 2006. Many of these environments have experienced BE change. Methods: One example of BE change is the addition of protected bike lanes and a bike share program in Washington, DC.Weselected an AMOS webcam that captured this change. AMOS captures a photograph from eachwebcamevery half hour.AMOScaptured the 120 webcam photographs between 0700 and 1900 during the first work week of June 2009 and the 120 photographs from the same week in 2010. We used the Amazon Mechanical Turk (MTurk) website to crowd-source the image annotation. MTurk workers were paid US$0.01 to mark each pedestrian, cyclist and vehicle in a photograph. Each image was coded 5 unique times (n=1200). The data, counts of transportation mode, was downloaded to SPSS for analysis. Results: The number of cyclists per scene increased four-fold between 2009 and 2010 (F=36.72, p=0.002). There was no significant increase in pedestrians between the two years, however there was a significant increase in number of vehicles per scene (F=16.81, p
