People react in many ways to
environments. To understand the groups’
identity and culture, the researcher can study the cues in these items:
1) The fixed structures: streets and buildings in cities, walls,
ceiling, floors, etc. The way in which these structures are arranged, their
spatial organization, location,
materials, and so on, communicate a certain meaning. Even the space
organization of the buildings and their relations to larger scales have a
pattern with a specific meaning.
2) Semi-fixed feature elements: changing the scale to a domestic one,
we can take street furniture, street signs, artifacts, houses furniture,
curtains, decoration, landscapes layouts, colors, clothes, etc. These elements
tend to communicate more meaning than the fixed structures, as they are
personalized and exempt from the Codes.
3) Non fixed feature elements: related to the human occupants or
inhabitants of settings, their spatial relation (proxemics), their body positions
and postures (kinesics) 6.
4) Other cultural meanings, as arts, written word, mythology, etc.
The human mind basically
works trying to impose meaning to the fixed and non fixed structures. By this
way, they are an expression of culture and identity and we can evaluate how the
group feels in the habitat, react to it. In Los Angeles and Orange County chicanos’ dwellings, once they
take possession, they complete them (through additions and icons), changing
them (in a cultural way). All these findings are cumulative and allow us to
make predictions on urban form (Rapoport, 1986).
Though complexity in morphology is always
present in the mexican immigrants’ areas, there are different reasons that make
them more or less complex. Let’s remember that the Building Code is the same,
applied for all houses and the Zonning code will change in each city, but
basically, we are considering 5’ set back at the sides, 15’ to the back, 20’ to
the front in average. Given these regulations, it could be expected to find the
same urban morphologies. We shall see the subtle differences in urban
morphology based on ethnic composition. Fractal geometry will be a tool to
demonstrate major differences based on the roughness of borders and occupation
of land.
Statistical Data of Ethnic composition
in percentages. Year 2000
METHODOLOGY
The investigation on urban fractality is
based on aerial photographs of areas of the cities above. The sectors involve
around three standard residential blocks, significantly showing the urban
shape. For the beach cities, the areas are not on the coast, as in this case
the lots are very narrow with high density houses in three stories, just for
the lots’ value. We tried to use the same scale, as much as possible. Anyway,
any change in scale is compensated for bigger or smaller streets and landscape
areas (empty areas for the drawings).
The patio covers, gazebos, tents, decks,
garages, storages, trellis were taken as part of the covered area.
The great quantity of trees7
and cars (and their shadows) in some cities, plus the changes in roof colors,
made us impossible to convert the jpg files directly into binary files to
calculate the fractal dimension with ImageJ. So, the criteria was to insert the
files in AutoCad, draw all the borders for occupied areas and then fill them
in. It was the only way to avoid confusion
in the shapes and occupancies.
The order in the following chart will
reflex the descendant percentage of Hispanic in order to see if the
Hispanic/white ethnicities (as majorities) are related to fractal urban
morphology .
These results let us
conclude that the areas with majority of latinos (and it has to be clear here
we mean now Mexicans and chicanos) have the highest fractal dimension, let us
say, the more complex urban morphology and development of borders, with lots of
atomized shapes as a consequence of higher rates of poverty.
There is a
positive association between socioeconomic status and acculturation. Acculturation
includes Protestantism, residence outside
the ghetto or barrio and contact with Anglos. Those who live outside
barrios are more likely to associate with Anglos on a personal basis, but some
researchers have found that upward mobility and residence outside the barrio do
not necessarily result in social
assimilation. In our experience, if Mexicans do not assimilate to Anglos’
habitats they are immediately denounced to the City authorities by their Anglos
neighbors. The usual case is the Mexican family renting a room to another
immigrant family. His Anglo neighbor will always call the City inspector. If
the Mexican American does not mend the situation, he will be pressed until
selling his house.
The investigations results show that the
odds of poverty among immigrants are nearly triple those of native-born
Mexicans. But these odds decline by about 16% for each additional 5 years in
the USA. (Crowley, Lichter, Quian, 2005). Here, we found the never-ending
cyclic succession of events, as every day more immigrants are entering the
country and more of them become acculturated. Acculturation implies subsequent
changes in the original cultural patterns and is a prerequisite for
assimilation.
Curiously, El Monte shows a low result,
but it is easily explained when we investigate its history.
El Monte history shows the following
ethnic composition through years:
1910: white immigration for the
exhuberant farms .
1930: 20% of Mexican population as
workers for farms. They lived in immigrants camps.
5%
of Japanese immigrants living in the farms.
Both
groups’s children had to attend to immigrants schools, separated from the white
children, who attended different schools.
1940: Demographic explosion, for the
small aircrafts factories in the zone.
2000: 72% hispanic population, 18% Asian,
7 % white.
The urban morphology has long been mixed
with the different activities, and the results for 2000 show the most complex
use of land, compared to other chicano’s cities in California.
The following is the use of land in
percentages:
10% Industrial
(specially Longo Toyota)
The percentages of industries-retails-
offices are the cause of empty spaces destinated to parkings, so D takes lower
values than any other cities with higher percentages of residential use.
Comparing to the other morphologies, El
Monte has big cells (industries) and small cells (houses) in the same lots.
For Santa Ana, in Orange County, the
empirical observation shows many illegal and alternative constructions. An
alternative is the tent. The City inspectors cannot apply the Zonning Code on
this ephemeral constructions 8.
It could be expected a higher result for D, but , the city is
under planning inspectors pressure and we estimate that the tendency will be to
reach lower D in the future, as a consequence for demolitions and additions in
second story, just for the change in
the FAR (land occupancy) from 50% in 2005 to 35% in 2006.
The morphology of Compton, though the
high composition of blacks, does not show any special difference comparing to
other latino cities. We see a reason here: the immigrant demand for family
housing has allowed older African-American residents to have unexpected gains
in home sales, as an aspect of “ethnic succession” (Mike Davies, 2000).
Huntington Beach and Newport Beach are
cities with higher composition of white. At first sight, -the same for the selected blocks in Downey-
the arrangement of houses is following a non fractal order, as kind of tiers.
The cells shown in Downey and Newport Beach are bigger and the few small shaded
areas are for gazebos and patio covers. Cells in Huntington Beach are typical
for three bedrooms and two cars garage in one story. In this case, the cells
are copied (literally speaking), mirrored and rotated, what left the
neighborhood in a complete state of uniformity.
It is not surprising the high value of D
for Newport Beach, as the lots are narrower and the houses very big.
It is important to notice that D is not
an indicator of different morphologies; as seen above, different arrangements
could have similar D values. So, we propose to measure D as an indicator for
borders roughness. The higher D value, the higher roughness.
Now, analyzing edges, their complexity is
consistent with the chicano culture: the higher values for the highest latino
areas; and looking inside this morphology, it makes sense finding more
partitions: the Mexican Americans and natives in regions outside the S West are
less likely to own their own homes and they are more likely to live in multiple
families households.
Studying
one and four blocks of East Los Angeles and we can see the fractal properties of urban morphology based on
the –certain- autosimilarity of D values. And what is more, D value is
approximately the same for bigger areas of the same neighborhood.
“Certain forms are taken for granted and
strongly resist change, since societies like these tend do be very tradition
oriented. This explains the close relation between the forms and the culture in
which they are embedded, and also the fact that some of these forms persist for
very long periods of time. With this persistence the model is finally adjusted
until it satisfies most of the cultural, physical, and maintenance
requirements.”(Rapoport, House, Form and Culture, chapter 1, 1969)
As the fractal shape of cities is not a
direct manifestation, it is necessary to look for the hidden pattern; the
fractal structure can be easily identified with aerial pictures, and the data
can be transformed to get a model
between theory and reality. Every step has to be immerse in
interdisciplinarity, as to avoid reading the objects only in their conditions
as objects, in the strict sense of epistemology.
One of the conditions to demonstrate if a
certain urban shape is fractal or not, is the autosimilarity through scales.
In regional scale, in terms of spatial
organization Los Angeles, since its beginning is was a primate barrio with
small satellites (now polycentric barrios), but the segregated city is shaped by class and race; watching the
ethnicity maps, we see a city within a city.
“In every instance, the second language
or racial group is concentrated in one or two sprawling districts with various
small outliers. There is none of the complex fractal geometry that
characterizes Latino Los Angeles with its hundred Spanish-speaking
neighborhoods and subdivisions radiating from the old Eastside core . ….The
Anglo-majority neighborhoods, mostly near the beach or in the foothills, are
becoming a gilded periphery to the bustling Latino metropolis in the coastal
plain…” ( Mike Davies, 2000)
Spatial logic is revealed in the
industrial land-use zoning, occupied now by latinos,9 and the
incorporation of former migrant labor camps into the geographic boundaries of
the metropolitan area. (See Anne Santiago, 1989). For Mexican Americans, it
seems that they will always be set apart, despite any acculturation for their
propensity to be geographically stable and to build up large local kin
networks.
New models of research, indicate –without
denying the discrimination by other groups- that ethnic groups do not
assimilate because members find it psychologically rewarding to be with “their
own kind”. This typical behaviour was advantageous for realtors in the old
times, who excused themselves of not selling properties to Mexicans and other
no Anglo communities . “ Barrioization allowed those concerned with segregation
to offer that one could even count on the ethnic populations of Southern
California to do the work of segregation themselves! “The Japanese, Mexican and
colored population have segregated themselves in groups largely according to
their own wishes”, stated a satisfied realtor from Riverside”. (W. Deverell,
2004)
Changing the scale to barrios10,
(neighborhoods) the situation is different. In an effort of finding an
identity, in the 1970’s the chicanos simplified their cultural heritage
considering themselves of indigenous origins of Southwestern Aztlan, leaving
behind the diversity heritage of Olmec, Tarascan, Zapotec, Mayan, Moriscos and
even Conversos… The spatial organization seems to reflex the diversity; it
becomes disaggregated, a mixing of different size cells, confronting the Code
in “instant slums” built with any kind of construction materials in the
homeowners’ hope of getting an extra income. The slums include substandard
partitioned garages, and basements conversions.
“Latinos are struggling to reconfigure
the “cold” frozen geometries of the spatial order to accomodate a “hotter”,
more exuberant urbanism”. (M. Davies, 2000)
The materials layers are reflected in the
social processes which give them birth: in other related words, “successive
waves of immigrant newcomers continually refresh the Latino population,
producing continuous demographic change and layering of the family structure
and household composition”. (R. Suro, 2002)
As we’ll see in another paper, the
autosimilarity is demonstrated between the barrio scale and the domestic scale,
as D reaches values rounding 1.70-1.80.
We suggest that there are some specific
reasons for which cultural Mexican (chicanos) areas in California are really
strong and keep their urban characteristics. Mexicans become assimilated more
slowly than other ethnic groups.
Concentration, complexity, plurality of
materials, culture –identity- and poverty is historically related . Income is
lower for individuals who live in highly concentrated areas. It seems that
those who have low incomes might choose live in concentrated areas because the
rents are lower11. (Lazear, 2005). As housing demand exceeds supply,
interaction between Hispanic subgroups will increase. (Anne M. Santiago, 1989).
“This is consistent with the findings of Schnare who suggests that as the
population gets larger, there is a filling in of residential areas which
diminishes the likelihood of contact with other groups”. (Anne Santiago, 1989)
The step forward to a better social
position, on the other hand, consequently indicates a loss of identity
(associated to ethnic religion)12 and fractality in urban forms,
though the kin ties are still kept.
We also suggest that Chicanos and Mexican
immigrants transplant fractal urban forms from Mexico to U.S. through the
history. Even the fractal morphology of Mexican archaeological cities like in Mayapan
have been proved. ( see Brown, Witschey and Lievobitch. Journal of Archaeological Method
and Theory, Vol. 12, No. 1, March 2005)
Nowadays, (Citing Peter Ward) in relation
to Mexico slums, Davis calls out the “heterogeneity of irregular settlements
that undermines collective response by dividing settlements on the basis of mode
of land acquisition”… (Davis, 2006)
An excellent example of fractality
constituted by composition of fragments of materials (trash from the factories)
is seen in the Tijuana, frontier as an alternative technology. People uses cars
tires to fix the lots’ slopes, and for the houses, parts of plastic, wood,
appliencies (electrodomésticos), cars’ bodies, etc. (See Eloy Mendez Sanz,
1996).
These fragmented –fractal- intuitive
designs are also part of the domestic scale and are –as we have seen illustrated by the old pictures- historically
incorporated in the culture, as buildings, festivities (see above the picture
of altar in the Dia de los Muertos) and in some aspects of art .13
Further investigation in arts, novels,
music, clothes, etc. will help in definitions.
Primarily we can sustain that Mexican
culture, extended to Chicano rich culture with indigenous roots, 14
has fractal characteristics with a constant value for D between 1.70 and 1.80
in all aspects of scale, that cannot be hidden even under the hardest Codes of
Building and Planning impossed by other cultures.
(1) Edward Soja refers to this situation as “socio spatial dialectic”.
Things in space and thoughts about space, as we see it, are inseparable.
(2) Chicano and Mexican American seem to have different meanings.
“Chicano” is both an ethnic and political designation; it is a label created in
the US and by the Mexicans themselves. In Anthony Reyes’ interview, he likes
“Chicano” because it indicates that a person is American without denying his
Mexican heritage. On the other side, Anna Fuentes feels that Chicanos are too
“radical” and too violent for her taste. Finally, Anna decided to call herself
“Mexican American” (see Keefe and Padilla. Cultural Blends chapter, page 87 and
93 in Chicano Ethnicity). Both words
together implies “Anglo”, transitively a Mexican American feels “in between”
the two cultures.
(3) This ideology was supported by the Movie Industry in a fierce
attempt to any radical multiracial labor community.
(4) The cited project was initiated in 1994 in conjunction with the
Compton Local Planning Council, the Compton California Unified School District
and UCLA students and faculty to address the tensions between African American
and Mexican American communities.
(5) The problem for accommodations is aggravated by the rate of
fertility in Mexican women: Mexican Americans had an average of 5 siblings in
the 1980’s. (Anglos counted 2.5). See Keefe and Padilla, 1987. They have also
proved that there is no decline in extended familism with social and economic
assimilation and urbanization. On the contrary of what is typically thought,
wealthy Chicano keep their kinship by paying big parties.
(6) See the publications of Edward T. Hall on the subject.
(7) Despite of those planted by Public Works, trees are valued in this
investigation for both reasons: they could imply high quality areas and evoke
rural habitats. Their presence could be so strong as to be avoided completely.
This is the case for some suburbs in Bogotá, Colombia. Trees are not planted by
settlers as they evoke rural areas related to drugs and guerrillas. (Conference
by arch. Trujillo, in UGYCAMBA, Faculty of Architecture, Design and Urbanism of
Buenos Aires).
(8) The FAR or occupancy percentage of use of land has been changed from
50% to 35% in 2006. Legally, most houses cannot grow anymore, at least on first
floor. Though chicanos have no possibilities to increase the area in order to
gain more bedrooms to rent, the alternative solution appears to satisfy the
necessities. The addition of tents or
the single room mobile home on wheels.
(9) Anne Santiago states that level of Hispanic-Anglo segregation will
diminish over time as the Hispanic population assimilates into mainstream
American society. This not taken for guaranteed, because as she also notices, the 1970’s brought increased levels
of segregation between them. (See Anne
M. Santiago, Patterns of Residential Segregation Among Mexicans, Puerto Ricans
and Cubans in U.S. Metropolitan Areas. 1989
(10)
The ethnic boundaries are materialized
by barrios. The “barrio” is defined as the heart and soul of the Chicano “place”
community. And even, if Chicanos live outside the barrio, they still interact
in a network of “personal communities” beyond and including the barrio
community. The network barely supports other ethnic groups as Blacks, Anglos,
Asian Americans and minorities.
(11)
In our experience, we cannot take only
the rooms and divided garages. The mobile home on wheels is also found in many
lots as a trick
for
inspectors. When the mobile home is without wheels, and, in some cases with
concrete steps to get into it, the City inspector would ask to remove the
mobile home. But, without fixed
elements around, it has to be permitted. This temporary “dwelling” is typically
for immigrant men alone in order to have a “bedroom” and a small kitchenette;
the bathroom is used in the primary house. When the spouse joins him, they go
to a bedroom inside a house or a garage and leave the mobile home for another
man.
(12)
We mention religion intentionally. In
Mexican roots, catholic religion is highly representative of indigenous rites
and icons, which, like altars are complex in their organization. Becoming
protestant is loosing the indigenous rites. And loosing fractal cultural
images.
(13)
Gerardo Burkle Erizondo (2004) from
the Universidad Autónoma de Zacatecas has made a research on archaeological art
shapes. He found fractal patterns in the designs and D values were between
1.883 to 2. The software was Benoit Program version 1.3. In the tables he shows
values of 2.018 which, could be only justified by a deficient definition of
images or filters. See Gerardo Burkle

The suggestion is based on fractal
patterns found by researchers in the Aztec culture. The fractal organization of
Spanish’s descendants houses and decoration patterns is not a typical
characteristic in another American countries that had been historically
colonized by Spanish. Here, we refer specifically to Argentina, Chile, Perú,
Uruguay.
