Cada ciutat té els seus veïnats, camarilles i clubs, les línies amagades que uneixen i divideixen a la gent del mateix poble. Què podem aprendre de les ciutats mirant al que la gent comparteix online? Començant amb la seua ciutat, Baltimore, Dave Troy ha estat mirant els tuits dels habitants de la ciutat, que revelen qui viu allí i amb qui parlen, o amb qui no ho fan.

When we think about mapping cities,
0
620
1775
Quan pensem en crear mapes de ciutats
00:14
we tend to think about roads
and streets and buildings,
and streets and buildings,
1
2395
2805
tendim a pensar en carreteres,
carrers y edificis
carrers y edificis
00:17
and the settlement narrative
that led to their creation,
that led to their creation,
2
5200
2800
i la narrativa de liquidació
que portà la seva creació,
que portà la seva creació,
00:20
or you might think about
the bold vision of an urban designer,
the bold vision of an urban designer,
3
8000
2984
o potser penseu
en l’audaç visió d’un dissenyador urbà,
en l’audaç visió d’un dissenyador urbà,
00:22
but there's other ways
to think about mapping cities
to think about mapping cities
4
10984
2503
però hi ha més formes
de pensar en crear
de pensar en crear
00:25
and how they got to be made.
5
13487
2166
mapes de ciutats i com s’han de fer.
00:27
Today, I want to show you
a new kind of map.
a new kind of map.
6
15653
2093
Avui, vull ensenyar-vos
un nou tipus de mapa.
un nou tipus de mapa.
00:29
This is not a geographic map.
7
17746
1496
Aquet no és un mapa geogràfic.
00:31
This is a map of the relationships
between people in my hometown
between people in my hometown
8
19242
3131
Aquet és un mapa de relacions
entre les persones del meu poble,
entre les persones del meu poble,
00:34
of Baltimore, Maryland,
9
22373
1340
Baltimore, Maryland.
00:35
and what you can see here is that
each dot represents a person,
each dot represents a person,
10
23713
4417
I el que podeu veure ací és
que cada punt representa a una persona,
que cada punt representa a una persona,
00:40
each line represents a relationship
between those people,
between those people,
11
28130
3294
cada línia representa una relació
entre eixes persones
entre eixes persones
00:43
and each color represents a community
within the network.
within the network.
12
31424
3446
i cada color representa una comunitat
dins de xarxa.
dins de xarxa.
00:46
Now, I'm here on the green side,
down on the far right where the geeks are,
down on the far right where the geeks are,
13
34870
4862
Jo estic al costat de color verd,
baix a la dreta, on estan els geeks
baix a la dreta, on estan els geeks
00:51
and TEDx also is down
on the far right. (Laughter)
on the far right. (Laughter)
14
39732
3848
i TEDx també està
baix a la dreta. (Rialles)
baix a la dreta. (Rialles)
00:55
Now, on the other side of the network,
15
43580
2577
A l’altre costat de la xarxa
00:58
you tend to have primarily
African-American and Latino folks
African-American and Latino folks
16
46157
2960
solen estar principalment
els afroamericans i llatinoamericans
els afroamericans i llatinoamericans
01:01
who are really concerned about somewhat
different things than the geeks are,
different things than the geeks are,
17
49117
3590
que solen estar preocupats per coses
diferents de les que estan els geeks.
diferents de les que estan els geeks.
01:04
but just to give some sense,
18
52707
1441
Perque us feu una idea
01:06
the green part of the network
we call Smalltimore,
we call Smalltimore,
19
54148
2406
a la part verda de la xarxa
els que l’habitem
els que l’habitem
01:08
for those of us that inhabit it,
20
56554
1545
l’anomenem Smalltimore
01:10
because it seems as though
we're living in a very small town.
we're living in a very small town.
21
58099
2915
ja que ens sembla que vivim
en un poble molt menut.
en un poble molt menut.
01:13
We see the same people
over and over again,
over and over again,
22
61014
2034
Sempre veiem
a la mateixa gent
a la mateixa gent
01:15
but that's because
we're not really exploring
we're not really exploring
23
63048
2171
però això és perquè
en veritat no explorem
en veritat no explorem
01:17
the full depth and breadth of the city.
24
65219
2862
la profunditat i l’amplada de la ciutat.
01:20
On the other end of the network,
25
68081
1752
A l’altre costat de la xarxa
hi ha gent interessada
en coses com la música hip-hop
en coses com la música hip-hop
01:21
you have folks who are interested
in things like hip-hop music
in things like hip-hop music
26
69833
2937
i que s’identifiquen amb la vida
01:24
and they even identify with living
in the DC/Maryland/Virginia area
in the DC/Maryland/Virginia area
27
72770
3804
en l’àrea de WashingtonDC/Maryland/Virgina
01:28
over, say, the Baltimore city
designation proper.
designation proper.
28
76574
4416
més que amb
la del propi Baltimore.
la del propi Baltimore.
01:32
But in the middle, you see that there's
29
80990
2100
Però al centre, es veu
01:35
something that connects
the two communities together,
the two communities together,
30
83090
2483
que alguna cosa
connecta a les dues comunitats,
connecta a les dues comunitats,
01:37
and that's sports.
31
85573
879
els esports.
01:38
We have the Baltimore Orioles,
the Baltimore Ravens football team,
the Baltimore Ravens football team,
32
86452
3088
Tenim als Oriols de Baltimore,
als Baltimore Ravens,
als Baltimore Ravens,
01:41
Michael Phelps, the Olympian.
33
89540
1446
a Michael Phelps, l’olímpic.
01:42
Under Armour, you may have heard of,
is a Baltimore company,
is a Baltimore company,
34
90986
2838
Under Armour, deveu conèixer-la,
és una empresa de Baltimore.
és una empresa de Baltimore.
01:45
and that community of sports
acts as the only bridge
acts as the only bridge
35
93824
2433
I aquesta comunitat dels esports
actua com l’únic pont
actua com l’únic pont
01:48
between these two ends of the network.
36
96257
2271
entre aquestes dues puntes de la xarxa.
01:50
Let's take a look at San Francisco.
37
98528
1895
Si mirem San Francisco,
01:52
You see something a little bit
different happening in San Francisco.
different happening in San Francisco.
38
100423
3186
podem veure que alguna cosa
diferent passa a San Francisco.
diferent passa a San Francisco.
01:55
On the one hand, you do have
the media, politics and news lobe
the media, politics and news lobe
39
103609
4393
Per una banda, tenim lòbul dels mitjans
de comunicació, política i noticies
de comunicació, política i noticies
02:00
that tends to exist
in Baltimore and other cities,
in Baltimore and other cities,
40
108002
2535
que tendeix a existir
a Baltimore i altres ciutats
a Baltimore i altres ciutats
02:02
but you also have this
very predominant group
very predominant group
41
110537
2355
però també hi ha un grup
molt predominant
molt predominant
02:04
of geeks and techies that are sort of
taking over the top half of the network,
taking over the top half of the network,
42
112892
4393
de geeks i techies que son els que
ocupen més de la meitat de la xarxa
ocupen més de la meitat de la xarxa
02:09
and there's even a group
that's so distinct and clear
that's so distinct and clear
43
117285
2502
i hi ha inclús un grup
molt distint i clar
molt distint i clar
02:11
that we can identify it
as Twitter employees,
as Twitter employees,
44
119787
2350
que identifiquem
com als treballadors de Twitter,
com als treballadors de Twitter,
02:14
next to the geeks, in between
the gamers and the geeks,
the gamers and the geeks,
45
122137
3367
al costat dels geeks, en mig
dels gamers i dels geeks
dels gamers i dels geeks
02:17
at the opposite end
of the hip-hop spectrum.
of the hip-hop spectrum.
46
125504
2941
just a l’altra punta
de l’espectre del hip-hop.
de l’espectre del hip-hop.
02:20
So you can see, though,
47
128445
1717
Però també es pot veure
02:22
that the tensions that we've
heard about in San Francisco
heard about in San Francisco
48
130162
2681
que les tensions que
sentim sobre San Francisco
sentim sobre San Francisco
02:24
in terms of people being
concerned about gentrification
concerned about gentrification
49
132843
2921
en quant a la gent que
està preocupada per la gentrificació
està preocupada per la gentrificació
02:27
and all the new tech companies
that are bringing new wealth
that are bringing new wealth
50
135764
2759
i les companyies tecnològiques
que porten una nova riquesa
que porten una nova riquesa
02:30
and settlement into the city are real,
51
138523
2097
i assentament a la ciutat són reals,
02:32
and you can actually see
that documented here.
that documented here.
52
140620
2229
i es pot veure que
estan documentades aquí.
estan documentades aquí.
02:34
You can see the LGBT community
53
142849
2020
Es pot veure que la comunitat LGBT
02:36
is not really getting along
with the geek community that well,
with the geek community that well,
54
144869
3296
no es porta be amb
la comunitat geek,
la comunitat geek,
02:40
the arts community, the music community.
55
148165
2132
la comunitat d’art
i la comunitat de música.
i la comunitat de música.
02:42
And so it leads to things like this.
56
150297
1773
I això porta a coses com aquestes.
02:44
["Evict Twitter"]
57
152070
973
[“Esborreu Twitter”]
02:45
Somebody sent me this photo
a few weeks ago,
a few weeks ago,
58
153043
1824
Vaig rebre esta foto
fa unes setmanes
fa unes setmanes
02:46
and it shows what is happening
on the ground in San Francisco,
on the ground in San Francisco,
59
154867
2907
i mostra el que està passant
a San Francisco
a San Francisco
02:49
and I think you can
actually try to understand that
actually try to understand that
60
157774
2384
i crec que realment
ho podeu entendre
ho podeu entendre
02:52
through looking at a map like this.
61
160158
1702
al veure un mapa com aquest.
02:53
Let's take a look at Rio de Janeiro.
62
161860
1760
Donem un cop d’ull a Rio de Janeiro.
02:55
I spent the last few weeks
gathering data about Rio,
gathering data about Rio,
63
163620
2454
He passat unes setmanes
recollint dades sobre Rio
recollint dades sobre Rio
02:58
and one of the things
that stood out to me about this city
that stood out to me about this city
64
166074
2807
i una de les coses que destaca
en aquesta ciutat
en aquesta ciutat
03:00
is that everything's
really kind of mixed up.
really kind of mixed up.
65
168881
2122
es que tot està mesclat
d’alguna manera.
d’alguna manera.
03:03
It's a very heterogenous city in a way
that Baltimore or San Francisco is not.
that Baltimore or San Francisco is not.
66
171003
4104
És una ciutat molt heterogènia,
no com Baltimore o San Francisco.
no com Baltimore o San Francisco.
03:07
You still have the lobe of people involved
67
175107
2455
Així i tot està el lòbul de gent
interessada en
interessada en
03:09
with government, newspapers,
politics, columnists.
politics, columnists.
68
177562
2384
govern, periòdics,
polítics, columnistes.
polítics, columnistes.
03:11
TEDxRio is down in the lower right,
right next to bloggers and writers.
right next to bloggers and writers.
69
179946
3404
TEDxRio està baix a la dreta,
al costat dels bloggers i els escriptors.
al costat dels bloggers i els escriptors.
03:15
But then you also have this
tremendous diversity of people
tremendous diversity of people
70
183350
2709
Però també hi ha una
gran diversitat de gent
gran diversitat de gent
03:18
that are interested
in different kinds of music.
in different kinds of music.
71
186059
2274
interessada
en diferents tipus de musica.
en diferents tipus de musica.
03:20
Even Justin Bieber fans
are represented here.
are represented here.
72
188333
2204
Es mostren inclús
els fans de Justin Bieber.
els fans de Justin Bieber.
03:22
Other boy bands, country singers,
73
190537
2892
Altres bandes, cantants country,
03:25
gospel music, funk and rap
and stand-up comedy,
and stand-up comedy,
74
193429
2908
musica gospel, funk, rap
i la comèdia,
i la comèdia,
03:28
and there's even a whole section
around drugs and jokes.
around drugs and jokes.
75
196337
3039
inclús hi ha una secció
sencera de drogues i bromes.
sencera de drogues i bromes.
03:31
How cool is that?
76
199376
1486
Què us pareix?
03:32
And then the Flamengo football team
is also represented here.
is also represented here.
77
200862
3134
I l’equip de futbol Flamengo
també esta representat aquí.
també esta representat aquí.
03:35
So you have that same kind of spread
78
203996
2160
Hi ha la mateixa diversitat
03:38
of sports and civics
and the arts and music,
and the arts and music,
79
206156
2715
d’esports, educació cívica,
i de les arts i la música
i de les arts i la música
03:40
but it's represented
in a very different way,
in a very different way,
80
208871
2161
però està representat
de forma diferent
de forma diferent
03:43
and I think that maybe fits
with our understanding of Rio
with our understanding of Rio
81
211032
3320
i crec que s’adapta
al que entenem de Rio
al que entenem de Rio
03:46
as being a very multicultural,
musically diverse city.
musically diverse city.
82
214352
4014
com una ciutat multicultural
i amb música diversa.
i amb música diversa.
03:50
So we have all this data.
83
218366
3618
Així que tenim aquestes dades.
03:53
It's an incredibly rich set of data
that we have about cities now,
that we have about cities now,
84
221984
3118
És un conjunt de dades increïble
el que tenim sobre les ciutats
el que tenim sobre les ciutats
03:57
maybe even richer than any data set
that we've ever had before.
that we've ever had before.
85
225102
3246
potser millor que qualsevol
conjunt de dades que hagem tingut.
conjunt de dades que hagem tingut.
04:00
So what can we do with it?
86
228348
1924
Què podem fer?
04:02
Well, I think the first thing
that we can try to understand
that we can try to understand
87
230272
2870
Crec que el primer és
intentar entendre que
intentar entendre que
04:05
is that segregation is a social construct.
88
233142
2338
la segregació és una construcció social.
04:07
It's something that we choose to do,
and we could choose not to do it,
and we could choose not to do it,
89
235480
3344
És una cosa que triem si volem fer,
i que podem triar no fer
i que podem triar no fer
04:10
and if you kind of think about it,
90
238824
1932
i si ho pensen
04:12
what we're doing with this data
is aiming a space telescope at a city
is aiming a space telescope at a city
91
240756
3411
el que fem amb aquestes dades
és apuntar un telescopi a una ciutat
és apuntar un telescopi a una ciutat
04:16
and looking at it as if was
a giant high school cafeteria,
a giant high school cafeteria,
92
244167
3032
i mirar-la com si fos
la cafeteria gegant d’un institut
la cafeteria gegant d’un institut
04:19
and seeing how everybody arranged
themselves in a seating chart.
themselves in a seating chart.
93
247199
3738
i veure com tothom ha planejat
una forma ordenada de seure.
una forma ordenada de seure.
04:22
Well maybe it's time to shake up
the seating chart a little bit.
the seating chart a little bit.
94
250937
3313
Potser és hora
de sacsejar-la un poc.
de sacsejar-la un poc.
04:26
The other thing that we start to realize
95
254250
2540
També comencem a adonar-nos
04:28
is that race is a really
poor proxy for diversity.
poor proxy for diversity.
96
256790
2638
de que la raça és
un pobre substitut de la diversitat.
un pobre substitut de la diversitat.
04:31
We've got people represented
from all different types of races
from all different types of races
97
259428
2937
Hi ha gent de tot tipus
de races representades
de races representades
04:34
across the entire map here --
98
262365
2326
per tot arreu del mapa.
04:36
only looking at race
99
264691
2376
Mirar nomes la raça
04:39
doesn't really contribute to
our development of diversity.
our development of diversity.
100
267067
2718
no contribueix
al desenvolupament de la diversitat.
al desenvolupament de la diversitat.
04:41
So if we're trying to use diversity
101
269785
1739
Si tractem d’usar la diversitat
04:43
as a way to tackle some of our
more intractable problems,
more intractable problems,
102
271524
3081
com una mena de fer front
als nostres problemes més intractables
als nostres problemes més intractables
04:46
we need to start to think
about diversity in a new way.
about diversity in a new way.
103
274605
3294
hem de començar a pensar
sobre la diversitat de forma diferent.
sobre la diversitat de forma diferent.
04:49
And lastly, we have the ability to create
104
277899
3527
Finalment, tenim l’habilitat de crear
intervencions per començar a canviar
la forma de les nostres ciutats
la forma de les nostres ciutats
04:53
interventions to start to reshape
our cities in a new way,
our cities in a new way,
105
281426
3094
04:56
and I believe that if
we have that capability,
we have that capability,
106
284520
2600
i crec que si tenim
aquesta capacitat
aquesta capacitat
04:59
we may even bear some
responsibility to do so.
responsibility to do so.
107
287120
3065
tenim la responsabilitat
de fer-ho.
de fer-ho.
05:02
So what is a city?
108
290185
1765
Què és una ciutat?
05:03
I think some might say that it is
109
291950
2206
Alguns diran que és
05:06
a geographical area or a collection
of streets and buildings,
of streets and buildings,
110
294156
3160
una àrea geogràfica o un conjunt
de carrers i edificis
de carrers i edificis
05:09
but I believe that a city
is the sum of the relationships
is the sum of the relationships
111
297316
2752
però jo crec
que és la suma de les relacions
que és la suma de les relacions
05:12
of the people that live there,
112
300068
1561
de la gent que l’habita
05:13
and I believe that if we can start to
document those relationships in a real way
document those relationships in a real way
113
301629
6051
i crec que si comencem a
documentar les relacions
documentar les relacions
05:19
then maybe we have a real shot
