    Abstract

    This report, the first of three, reviews methods and methodological approaches, qualitative and quantitative.In an effort to look beyond the qualitative-quantitative divide, two geographers with different methodologicalbackground andexpertise write together.This first reportreviews worksunder the broader context of hybridgeographies, the spatial turn, and the recent explosive growth of volunteered geographic information (VGI).The works reviewed seek to combine methodological approaches in creative ways, or to create other hybridresearch methods, all to address the challenging problems of our times problems that often demand synergyin methodology, holism in ontology, plurarism/open-mindedness in epistemology, and embracing diversity.

    I Introduction: Beyond thequalitative-quantitative divide

    With this first in a series of three reports we

    begin an entirely new progress report, one set

    to cover qualitative and quantitative research

    methods together, along with the methodologies

    that ground them and the approaches that seek to

    integrate them. We write together in an effort to

    bury the qualitative-quantitative divide in our

    discipline (and in the social sciences and huma-

    nities more broadly) and we contend that this

    divide has hindered cooperation, collaboration,

    and constructive engagement of diversity (Curtis

    and Riva, 2010; Walker, 2010). In this first

    report we focus on work that seeks to mix meth-

    ods and/or methodologies, as well as on work

    that seeks to transcend the differences between

    methods and methodologies. This should notbe confused with single-minded advocacy for

    such work as the methodological way forward.

    Future reports will highlight qualitative and

    quantitative approaches that do not seek to meld

    approaches, but attempt instead to carry out their

    own methodological work well. Across the three

    reports we seek to recognize the diversity of

    approaches current in geographical scholarship,

    but also to propose that we move beyond the

    methodological divide that has hindered that

    scholarship. Our goal is to inject tolerance, strive

    for synergy, and embrace diversity in our meth-

    ods and methodologies in order to address crea-

    tively the complex problems of our time.

    Such a broad embrace is (and long has been)

    common in more introductory texts (Gomez and

    Jones, 2010; Kitchin and Tate, 1999; Montello

    and Sutton, 2005) and throughout the history ofgeography. Yet, though this is a vibrant time of

    publication on methods and methodologies in

    geography, that broad-spectrum view remains

    elusive in work that seeks to engage issues of

    methods at a higher level, where, with few excep-

    tions (Cope and Elwood, 2009; Crampton, 2010),

    recent advanced texts in geography are, perhaps

    necessarily, specialized (Bivand et al., 2008;

    DeLyser et al., 2010; Hay, 2010; Longley et al.,

    2010; OSullivan and Unwin, 2010) even as othersplace a growing emphasis on mixed methods for

    synthesis and holistic understanding (Carpenter

    et al., 2009; Tashakkori and Teddlie, 2010).

    On the surface, the qualitative-quantitative

    divide appears as different methodological

    approaches. Yet it may also reflect a much deeper

    division in human intellectual endeavor and

    knowledge production, akin to C.P. Snows

    chasm between scientific and humanistic

    knowledge (Snow, 1993). In such situations,

    divides can be just that: divisive. If our research

    and our discipline are to survive and remain rele-

    vant, we must move beyond divisiveness. This is

    not to say that we must set aside all divisions and

    differences, for such diversity and debates on fun-

    damental issues are productive whether for an

    academic discipline or a democracy (Fineman,

    2009). This can be a fruitful time for methodologi-

    cal engagements that might better serve

    geography as an interdisciplinary field (Baerwald,

    2010). In the following section we outline the

    broader context for such engagements.

    II Geographys new turn tosynthesis and holism

    Geography as a discipline has oscillated between

    analytical and synthetic paradigms (Harvey,

    1997; Turner, 1989). During the first decade of

    the 21st century, along with geographers cur-

    rent and recent turns to specific domains and

    approaches (e.g. the critical turn, the cultural

    turn, the relational turn, the computational turn,

    the communicational turn, the mobilities turn,

    the performative turn, etc.), one turn deservesparticular attention here: the turn to synthesis

    and to holism. At least three trends over the past

    10 years provide broader context for this syn-

    thetic and holistic turn.

    First, there are calls for a unified geography as

    the new disciplinary identity (Matthews and

    Herbert, 2004), for a new synthesis (Gober,

    2000), and for studying our planet not bit by bit

    but all at once (Clarke, forthcoming). As a con-

    ceptual framework, hybrid geographies proposeto practice this new synthesis in geographic

    research: Whatmore argues that it is both more

    interesting and more pressing to engage in a

    politics of hybridity . . . in which the stakes are

    thoroughly and promiscuously distributed

    through the messy attachments, skills and inten-

    sities of differently embodied lives whose every-

    day conduct exceeds and perverts the designs of

    parliament, corporations and labour (Whatmore,

    2002: 3). For Rose (2000: 364), hybrids trans-

    gress and displace boundaries between binary

    divisions and in so doing produce something

    ontologically new; this notion is echoed by

    Kwan (2004:759) who recognizes two major

    divisions within geography: the partition between

    physical and human geography, of nature from

    society; and the separation of spatial-analytical

    geographies, which attempt to create a mode of

    disembodied geographical analysis, from social,

    112 Progress in Human Geography 36(1)

    cultural, and political geographies. For these

    scholars, hybrid geographies seek to integrate in

    grounded practices elements thought to be

    incompatible or conflicting. Hybrid geographies,

    also sometimes known as boundary projects,

    challenge existing boundaries and forge creative

    connections within geographies physical and

    human, critical and analytical, qualitative and

    quantitative aiming to integrate perspectives

    on space, place, flow, and connection.1

    Second, thefirst decade of this century has wit-

    nessed a spatial turn across the physical sciences,

    social sciences, and humanities, with scholars

    fromdifferent disciplineschallenging issues from

    a spatial perspective. Space has become an inte-

    grating theme across the social sciences evi-denced by emerging spatially integrated social

    sciences (www.csiss.org) and scholars across

    the humanities have made GIS and spatial analy-

    sis integral parts of their research methodologies

    (Bodenhamer et al., 2010; Fisher and Mennel,

    2010; Knowles, 2008; Scholten et al., 2009; Warf

    and Arias, 2008). Economist Paul Krugman was

    awarded the 2008 Nobel Prize for his work in eco-

    nomic geography. And recent work by mathema-

    ticians, physicists, computer scientists, andecologists in complex networks, visual analytics,

    and spatial modeling has enhanced geographys

    quantitative toolbox.

    This spatial turn has not been confined to the

    Ivory Tower. Policy-makers have realized the

    crucial importance of space and place in under-

    standing the complexity of the worlds problems,

    seeking solutions to these problems that will

    work well under diverse local circumstances

    the World Bank (2009) framed last years world

    development report entirely from a geographical

    perspective, concluding that alleviating, and

    eventually eliminating, poverty problems must

    start with reshaping the worlds economic geo-

    graphy. In the USA, the Obama White House has

    urged all federal agencies to develop place-based

    policies (Orszag et al, 2009).

    Third, there is the merger of new means of

    understanding spatial data with new ways of

    creating and acquiring it. The first decade of this

    century saw the rapid development of Web

    2.0 technologies along with major advances in

    GeoWeb and geospatial technologies, including

    traditional geographic information systems

    (GIS), remote sensing (RS), global positioning

    systems (GPS), and location-based services

    (LBS). This is an unprecedented moment in

    human history: we can now know where nearly

    everything, from genetic to global levels, is at all

    times. These technological advances can be

    brought to bear on the corresponding data ava-

    lanche the vast amounts of user-generated con-

    tent and volunteered geographic information

    (VGI) that pours out as individuals become sen-

    sors, gathering and disseminating data abouttheir environments and themselves in increasing

    spatial-temporal detail.

    Advances in geospatial technologies during

    the past 10 years have enabled ordinary citizens

    with little formal training to participate in the

    production of geographic data and knowledge

    through diverse forms of user-generated content

    and VGI. Neogeography has emerged as a

    descriptive and analytical tool for large numbers

    of people outside of academia, a process cata-lyzed by digital mapping technologies and the

    social-networking practices of Web 2.0 (Batty

    et al., 2010). The rise of neogeography during

    the past five years has contributed to the explo-

    sive growth of a diverse array of geo-tagged

    data, and stimulated a new mode of knowledge

    production via crowdsourcing (Goodchild,

    2009). Neogeography and VGI may not mean

    much when viewed at the individual level, but

    interesting patterns may emerge when the vast

    amount of fragmented individual-level data is

    aggregated and synthesized.

    III Recent efforts in geographicsynthesis: A step towardconsilience?

    This section reviews recent efforts towards

    geographic synthesis that reflect the three trends

    Sui and DeLyser 113

  • 7/30/2019 Sui Delyser Cross Qual Quant i

    4/15

    outlined above. All these efforts aim to move

    beyond the qualitative-quantitative divide, and

    a narrow view of geographical scholarship. For

    each hybrid we give a synoptic overview, and

    offer more detailed discussion on methods and

    methodologies in representative case studies.

    1 Hybridizing physical and humangeography

    Although geographers following the cultural/

    political ecology tradition have for decades

    worked on topics that link physical and human

    geography, the growth of hybrid geographies has

    drawn an increasing number of human and phys-

    ical geographers (who normally would practiceeither one exclusively) to cross the physical-

    human divide. Neil Smith (1998) speculates on

    the emergence of what he called El Nino capital-

    ism both literally and metaphorically noti-

    cing the striking similarities in the rhythms of

    El Nino/Southern Oscillation (ENSO) and capit-

    alisms periodic crises, and striving to link them

    in a causal chain. El Nino capitalism remains

    controversial, and others dispute the extent

    ENSO has affected US macroeconomicperformance. Using data for ENSO fluctuations

    and the rates of US inflation and economic

    growth over the 18941999 timespan, Berry and

    Okulicz-Kozaryn (2008) explore whether there

    has been any co-cyclicality between the two phe-

    nomena and whether aperiodic ENSO shocks

    have had any impact on these macroeconomic

    parameters. They discerned no co-cyclicality or

    aperiodic shocks, concluding that while ENSO

    may briefly influence the performance of particu-

    lar sectors of the economy in particular regions,

    such locally important effects vanish into the

    noise surrounding macroeconomic trends in an

    economy as large and complex as that of the

    USA (p. 625).

    Leichenko et al. (2010), however, attempt to

    relink the current global financial crisis to global

    climate change using a double-exposure frame-

    work. Their empirical results from Californias

    Central Valley support the link between global

    climate change, global financial crisis, and how

    those are manifested from global to local levels.

    Meanwhile, Gober et al. (2010a) saw that global

    climate change presented an uncertain future for

    urban water planners, particularly in desert areas

    (like metropolitan Phoenix where they situated

    their work). The potential local impacts of

    large-scale processes like global climate change

    were difficult for urban planers to grasp and

    apply, so Gober et al. (2010b) downscaled global

    climate models to the size of metro Phoenix,

    applying those together with urban-runoff predic-

    tions and inputting the data into WaterSim, an

    integrated computer-based modeling program

    that could simulate scenarios for Phoenixs waterresources based on different projected climates,

    water-management policies, and water-usage

    demands. The model enabled the suspension of

    politicized decisions relating to global climate

    change, in order to show how endangered a

    resource the citys water would be under even

    optimistic scenarios, while also revealing

    that adaptive policies encouraging residential

    conservation could lead to long-term water sus-

    tainability even under the worst climate-changescenarios.

    It is not only human geographers addressing in

    new ways topics typically thought physical

    (Campbell, 2009; Yusoff, 2009, 2011); physical

    geographers have also embraced topics more tra-

    ditionally human (Frazier et al., 2010; Mark et al.,

    2010; Valdivia et al., 2010). The study of globa-

    lization, as Clifford (2009) suggests, need not

    be the exclusive domain of human geographers

    or social scientists: physical geography has

    always been global at heart, and globalization

    must be seen historically in the global export of

    western science including physical geography

    that underpinned colonialresource exploitation.

    Inspired by Allan Preds work (1984) on the

    formation of place, Phillips (2001) highlights the

    primacy of place in human impacts on the envi-

    ronment, and contingency of place has been a

    dominant theme in his recent publications

    114 Progress in Human Geography 36(1)

  • 7/30/2019 Sui Delyser Cross Qual Quant i

    5/15

    (Phillips, 2009a, 2009b). In a parallel to human

    geographers efforts to examine economic

    impacts of global climate change, physical geo-

    graphers have studied the environmental conse-

    quences of the rising divorce rate. Yu and Liu

    (2007) tracked carbon footprints of couples in

    12 countries who married and then either

    divorced, stayed married, or divorced and remar-

    ried. Because divorced couples typically require

    two residences, Yu and Liu found that energy

    consumption, water usage, and the amount of

    space occupied per person all increased dramati-

    cally with divorce.

    In hydrological modeling, Odoni and Lane

    (2010) advocate an approach that is knowledge-

    theoretic rather than data-theoretic in order tocapture the richer sources of information avail-

    able to the modeler. Such sources include third-

    party reports, personal recollections and diaries,

    old photographs and press articles, and opinions

    which have been, by convention, either excluded

    from analysis, or simply added into descriptions

    of model results at the point of dissemination and

    consultation. This framework represents an effort

    by physical geographers to embed qualitative

    data as an integral part of their quantitative mod-els: as they argue, the production of scientific

    knowledge comes to include not just scientists

    and specialists, but also those people for whom

    model predictions make a material difference

    (p. 151).

    Continental philosophy has likewise become a

    source of methodological reflection for physical

    geographers. Using Nietzsche, Comrie (2010)

    aimed to engage physical geographers and fellow

    physical scientists to reconsider their roles as

    scientists. Debunking the mystiqueof science and

    the misconception of seeing science as indepen-

    dent of people and society, Comrie showed that

    science gains its power by the ways we attach

    meaning to it and its findings: we should thus act

    on our ability to bestow that power. Comrie chal-

    lenges physical geographers to overcome their

    trained tendency toward detached environmental

    science and instead fashion a new physical

    geography that includes meaning and action.

    Mistry et al. (2009), drawing from their work on

    water quality in Guyana, traced their journey as

    physical geographers from top-down experts to

    participatory facilitators addressing issues of

    reflexivity and positionality often (mistakenly)

    thought only of concern to human geography.

    2 Mixing qualitative and quantitativemethods

    The interdisciplinary nature of geography

    (Baerwald, 2010) can foster a methodological

    hybridity in the mixing of qualitative and

    quantitative methods and methodologies. Recent

    work features sophisticated mixed-methodsapproaches that cross the divide between

    spatial-analytical and social-critical approaches

    (Barker, 2009; Brown et al., 2008; Collins,

    2009; Elwood, 2010; Lopez-i-Gelats et al.,

    2009; Schuermans and De Maesschalcka, 2010;

    Travlou et al., 2008; Tschakert, 2009; Velazquez

    et al., 2009; Zulu, 2009), revealing the binary

    between such approaches as pseudo rather than

    real (Barnes, 2009). Critical geography need not

    be qualitative and can use numbers (Schwanenand Kwan, 2009) afterall, Karl Marx used quan-

    titative methods extensively. But, as Elwood

    (2010) points out, thoughtful mixed-methods

    research must bridge not only methodological but

    also epistemological and philosophical divides.

    Cherished theoretical principles may become

    renegotiated: Bergman et al. (2009: 265) seek

    nothing short of a methodological reinterpreta-

    tion of what employing mathematical arguments

    could mean within larger, postpositivist theoreti-

    cal projects in critical human geography.

    Mixed-methods research offers human geogra-

    phers the opportunity to identify appropriate roles

    for different methods (Elwood, 2010). In transport

    geography this may involve exploring how con-

    text affects human travel behavior. Zoliniks

    (2010) multilevel, mixed-methods approach to the

    criticisms of quantitative methods in transport

    geography shows that quantitative modeling (at a

    Sui and DeLyser 115

  • 7/30/2019 Sui Delyser Cross Qual Quant i

    6/15

    single level) can complement qualitative analysis

    (across multiple levels). Goetz et al. (2009) exam-

    ine recent transport-oriented research in highly

    cited geography journals, revealing that geogra-

    phical research on transport topics is more preva-

    lent and (though often influenced by civil-

    engineering approaches) reflects a wider range

    of epistemological and methodological

    approaches than frequently assumed. They pro-

    pose a critical-transport-geography research

    agenda that calls for the greater integration of

    qualitative analysis into predominant

    quantitative-modeling approaches.

    Perhaps most dramatic in mixed-methods

    research in human geography is the development

    of qualitative GIS (Aitken and Kwan, 2010),which, along with participatory GIS, feminist

    GIS, and critical GIS, works to reconceptualize

    GIS as more than only quantitative in terms of

    data, analysis, and representation. Emerging in

    response to critiques that characterized GIS as

    rooted in positivist epistemologies and most sui-

    ted for quantitative techniques associated with

    the discredited spatial science (Wilson, 2009),

    qualitative GIS reveals that GIS, from its incep-

    tion, has been more than quantitative (Cope andElwood, 2009: 171). Using mixed/hybrid meth-

    ods in representation, mode of analysis, and con-

    ceptual engagement, qualitative GIS embraces

    non-cartographic forms of data, qualitative anal-

    ysis, and multiple modes of representation (Cope

    and Elwood, 2009).

    Furthermore Knigge and Cope (2006, 2009)

    show how the inductive, iterative analysis prac-

    tices of grounded visualization can engage scale

    in GIS as both a cartographic representation and

    a sociopolitical construction. Elwood (2009),

    drawing from her work on grassroots GIS prac-

    tices, demonstrates how cartographic representa-

    tions generated in a GIS might be engaged to

    produce multiple and different understandings of

    neighborhood, negotiating the meanings and char-

    acteristics associated with neighborhood as flex-

    ible and fixed, and engaging them as both

    material and imagined space. And Aitken and

    Craine (2009) show how a non-representational

    reading of GIS-based representations can illumi-

    nate greater insights into affective and emotive

    politics than more traditionally technical readings.

    3 Archival ethnography

    Ann Laura Stoler (2009) urges a move away

    from treating the archives as an extractive exer-

    cise (p. 47), advocating applying ethnographic

    sensibilities to archival research. This shift, from

    archive as source to archive as subject (p. 44)

    is not entirely new (Darnton, 1984; Ginzburg,

    1982), but this hybrid form of research has been

    forwarded by a number of geographers. As

    Ogborn (2009: 18) advises, We can examinearchives . . . [by] asking ourselves what forms

    of communication are they? both when they

    were created, and in communicating between

    past and present. Lorimer and Philo (2009) do

    just that in their endeavor to allow more disor-

    der into the archive through their investigation

    of the haphazardly kept and collected archive

    of their own geography department. They point

    out that the researcher needs to be suspicious

    of the apparent order, and instead seek outcracks in the facade because a disorderly

    archive need not yield a disordered account, nor

    must an ordered archive yield an orderly one:

    the most conventionally ordered accounts . . .

    may also be the ones that miss what is most

    important (Lorimer and Philo, 2009: 229, 250).

    Lambert (2009) employs an ethno-historical

    approach, identifying blanks within the written

    record to understand the identities and histories

    of enslaved witnesses and excavate their knowl-

    edge from colonial archival traces (p.48), demon-

    strating how even the unsaid can become

    evidence (p. 58). Others, like Cameron and Mat-

    less (2010), also found things thought not acces-

    sible in archives. Studying an ecological field

    course in the UK, they showed how even ignor-

    ance itself (in this case the ignorance of local agri-

    cultural practices that course participants had

    mistaken for natural processes)mustbe achieved

    116 Progress in Human Geography 36(1)

  • 7/30/2019 Sui Delyser Cross Qual Quant i

    7/15

    and sustained and how this ongoing operation

    can be revealed in the archives.

    Neither must non-humans be left from the

    archives, though their tracks can be difficult to

    trace. Lorimer and Whatmore (2009) draw on

    emerging techniques in embodied re-enac-

    tive historical geography in their study of ele-

    phants and an elephant hunter in 19th-century

    Ceylon: scrutinizing the hunters published

    works, journals, and sketches; examining the

    hunters clothing, equipment and rifle crushed

    by an elephant; and conducting fieldwork at the

    sites of Sri Lanka hunts, re-reading key texts in

    situ as a partial means to understand the archives

    from a more-than-human perspective. Nor must

    the archive be understood as merely a textualrealm. For Ogborn suggests understanding a

    world of practice as simultaneously a world of

    communication (rather, perhaps, than represen-

    tation) can provide a way forward for historical

    geographers to explore practices without simply

    turning our backs on what we have learned about

    the world through texts (Ogborn, 2009:19). So

    too must the understanding of archival practices

    extend to those doing archival research. Bailey

    et al. (2009) detail the backstage productionof their work in a Methodist archive, writing a

    group-autoethnography-in-an-archive because

    research methods and reportage cannot be

    abstracted from the practices and experiences

    of the researchers. Similar to Mistry et al.

    (2009) above, they encourage the development

    of an enlivened geography in which practitioners

    acknowledge their voices (Bailey et al.,

    2009:265, 258, 266).

    4 Activism, applied geography, andacademia

    Community engagement, either in the form of

    Participatory Action Research (PAR) (Reason

    and Bradbury, 2007), or applied geography

    (Pacione, 1999), draws on strong traditions in

    the social sciences and humanities, and involves

    different hybridizations of research, pedagogy,

    participation, political action, and caring. Geo-

    graphers working in this area, like the Automo-

    mous Geographies Collective (2010), reject the

    false distinction between academia and wider

    society, seeking instead ways to research and

    engage collectively, in part by recognizing the

    emancipatory potential of education, research

    and publications (pp. 245, 263). Evans et al.

    (2009) advocate a fusion of methods across sub-

    fields previously thought unconnected, arguing

    that such linkages can be usefulparticularlyin col-

    laborative, community-based work, where they

    can help recognize indigenous peoples as the

    authors, not objects, of knowledge (see also Jazeel

    and McFarlane, 2010). And Gibson-Graham

    and Roelvink (2009: 343) advocate a hybridresearch collective of human and non-human

    actants to stimulate world-changing processes.

    Part of the challenge, as Askins (2009) points

    out, is that although our research, teaching,

    learning, and activism are shaped by emotions,

    this is often under-acknowledged. She urges

    academics to make time and space for emotions

    in every stage of research. But emotions, accord-

    ing to Brown and Pickerill (2009) are linked to

    the very sustainability of activism, for activismis sustained through emotional engagements and

    emotional reflexivity. The meanings and prac-

    tices of emotional reflexivity must be examined

    by researchers in the context of the different

    spaces of activism, for spaces themselves may

    hinder or enable emotional reflexivity in acti-

    vism. Such awareness, they argue, can be a first

    step to sustainability of activism.

    Another avenue for activist work seeks to link

    activism and involvement explicitly with peda-

    gogy (see Boyer, 1990), drawing students into

    academic and community practice. Mountz

    et al. (2008) linked their course with a local

    community-service center, allowing research

    questions and class projects to emerge organi-

    cally through dialog, and only then askingto col-

    laborate with organizations whose work

    resonated with the themes that had emerged, and

    thus laying a framework for meaning

    makingoutside the classroom (p. 228). Course

    evaluations, community partners, and presenta-

    tion attendees all responded positively to theproj-

    ects, yet the time and energy commitments of the

    course proved overwhelming for many even

    while it also became a defining part of. . .

    [their]

    lives (pp. 233, 235). Despite the challenges, inte-

    grating Participatory Action Research withteach-

    ing, as Pain (2009) points out, links theory to

    practice, and enables conceptual and methodolo-

    gical learning to be situated both in and out of the

    classroom (see the symposium on this topic:

    Cope, 2009; Elwood, 2009; Kindon and Elwood,

    2009; Moss, 2009).

    5 Mashing up paleo- and neogeography

    The explosive growth of volunteered geographic

    information (VGI) has precipitated a possible

    new divide the so-called neogeography versus

    paleogeography (Sieber et al., 2009; Sui, 2009a).

    If neogeographers are those with little or no for-

    mal geographic training who contribute geo-

    graphic information on a voluntary basis using

    the technologies loosely known as Web 2.0,

    then, by implication, professional geographersare paleogeographers. While this division is

    used only loosely and sometimes sarcastically,

    it has been on the increase.

    Many forms of synthesis in the context of

    VGI applications can be described as mashups

    (the term, borrowed from the music industry,

    originally referred to a composition created by

    blending two or more songs). In the context of

    Web-based applications, a mashup may have

    multiple meanings (Sui, 2009b). At the func-

    tional/service level, a mashup may be a Web

    page or application that combines data or func-

    tionality from two or more external sources to

    create a new service. In terms of content, a

    mashup can be a digital media file containing a

    combination of text, maps, audio, video, and ani-

    mation, which recombines and modifies existing

    digital works to create a derivative work. The

    term implies easy, fast integration, frequently

    using open APIs (Application Programming

    Interface) and data sources to produce some-

    thing new. A growing number of companies,

    including Google, Microsoft, Yahoo, and Map-

    Quest have developed products and services that

    enable their users to develop their own APIs for

    this purpose, and millions of Web users have

    developed creative applications. But a mashup

    is more than a technical advance its signifi-

    cance lies in its promotion of a new habit of

    mind towards synthesis and hybridity.

    Mashing up neo- and paleogeography has

    opened new avenues. Liu and Palen (2010) pre-

    sented a qualitative analysis of the design and

    creation of crisis-map mashups to describe emer-

    gent neogeographic practices in emergency man-agement and disaster relief. They analyzed the

    circumstances that led to mashup creation, data

    selection, and design choices vis-a-vis spatial

    and temporal information representation. Using

    Ushahidi and New Orleans repopulation maps

    as case studies, they further discussed the impli-

    cations of emergent neogeographic practices to

    illustrate benefits gained by merging profes-

    sional/paleo and participatory/neo geotechnolo-

    gies for crisis mapping, and the opportunitiesprovided by the blending of the two for improve-

    ment of geographic and cartographic literacy.

    Zook et al. (2010) document the role of mash-

    ing up neo- and paleogeographic information in

    the Haiti relief effort. They focused on four

    mashup efforts in particular: CrisisCamp Haiti,

    OpenStreetMap, Ushahidi, and GeoCommons.

    Both Liu and Palen, and Zook et al. found such

    mashups via online mapping sites a key means

    through which individuals could make a tangible

    difference in the work of relief and aid agencies

    without being physically present in Haiti.

    Goodchild and Glennon (2010) use forest-fire

    mapping as a case to examine the potential for

    VGI in time-critical scenarios, further demonstrat-

    ing the power of crowdsourced online mapping.

    User-generated content (UGC) and VGI in

    particular are also increasingly becoming an

    important data source, often mashed up with

    118 Progress in Human Geography 36(1)

    9/15

    more traditional sources for geographic

    research. Cidell (2010) reported the use of con-

    tent clouds (summarizing the contents of a doc-

    ument by depicting the words that appear most

    often in larger, darker type within the cloud) as

    a method of exploratory qualitative data analysis

    using primarily online information. When uti-

    lized as a form of qualitative GIS, content clouds

    provide a powerful way to summarize and com-

    pare information from different places on a sin-

    gle issue. Using Dell Computers customer blog

    (direct2Dell), which reveals communicative

    behavior directed both at seeking objective

    information and locating subjective experiences,

    Poon and Cheong (2009) show how blog data

    can be used to examine complex intersubjectiv-ity in economic geography. Other economic

    geographers have used blog data to examine

    agglomeration effects and the dominance of

    major metropolitan areas as information hubs

    (Jones et al., 2010; Mould and Joel, 2010).

    OLoughlin et al. (2010) have utilized data from

    WikiLeaks and the Afghan war to reveal micro-

    geographies, conflict diffusion, and clusters of

    violence in Afghanistan. Adding to the literature

    using geospatial technologies in human-rightsmonitoring (AAAS, 2010), Madden and Ross

    (2009) have mashed up multiple sources of

    online and offline interviews and personal

    narratives to illuminate patterns of genocide,

    human rights abuses, and atrocities in northern

    Uganda.

    IV Conclusions

    This report has reviewed broad trends that, from

    a methodological perspective, could have trans-

    formative effects on the practice of human geo-

    graphy. Although they embrace divergent

    approaches and methodologies to address com-

    plex issues, they also converge around a (re)turn

    to synthesis and holism in their aims. Hybridiz-

    ing, remixing, and mashing up conceptual fra-

    meworks, data sources, and modes of analysis

    as these works do may provide a means to cross

    the methodological, epistemological, and

    philosophical chasms that have divided human

    geography. And, while the most common

    hybrids involve combining the statistical analy-

    sis of population data with interviews of a

    smaller number of people, or supplementing GIS

    with qualitative data, we have endeavored to

    show some of the breadth in hybrid methods

    used by geographers there are others we have

    not discussed, such as collaboration between

    geographers and artists (Ahlqvist et al., 2010;

    Askins and Pain, forthcoming; Nabulime and

    McEwan, forthcoming). It is nevertheless true

    that a worrisome percentage of the works we

    searched for this report do not describe the meth-

    ods and methodologies employed whetherhybrid or not. Even so, the application and suc-

    cess of these hybrid geographies and mixed-

    methods approaches demonstrates that what

    were once perceived as methodological, episte-

    mological, and philosophical chasms not only

    can be, but have been, bridged.

    More than 30 years ago, Feyerabend (1975:

    305306) argued that everywhere science is

    enriched by unscientific methods and unscien-

    tific results, and that the very divisionbetween science and non-science was detri-

    mental for true understanding. Consistent with

    Fayerabends embrace of all methods, Wolch

    (2003) advocated radical openness itself as a

    method. Radical open-mindedness, coupled

    with an engaged pluralist approach as out-

    lined by Barnes and Sheppard (2010) can

    be a fruitful way forward.

    Mixing methods, as done by those whose

    work we have cited here, is but one way of

    engaging the multiple voices present in the

    sites and communities where our research is

    placed. All methods simultaneously enable and

    disable, and mixing methods is not the only

    way to approach methodological challenges.

    Nor would we wish to undermine the com-

    plexities and challenges in adopting a syn-

    thetic/holistic approach in research. As Wyly

    (2009) has noted:

    Sui and DeLyser 119

  • 7/30/2019 Sui Delyser Cross Qual Quant i

    10/15

    how can we ever find the time to master the dizzying

    array of traditions and techniques required to create

    truly hybrid geographies, without giving up the

    depth that comes with specialization in social theory

    or spatial econometrics or feminist ethnography or

    participant observation or policy analysis or the listgoes on? (Wyly, 2009: 319)

    Institutional culture may discourage transdisci-

    plinary research (Wainwright, 2010), and yet,

    as Turner (1989) argued, single-minded syn-

    thetic approaches do not necessarily serve the

    discipline well. Instead, balanced specialist-

    synthesis approaches adapted to each new

    situation may be the most successful methodolo-

    gical framework. Our future reports will examine

    methods, new and old, that seek to engage eitherqualitative or quantitative approaches, striving to

    do them each well and meld them creatively

    wherever and whenever needed.

    Note

    1. Effortstoward hybridityhave been supported at the fund-

    ing level as well. The US National Research Council

    (NRC, 2010) identified a transdisciplinary areathey term

    the geographical sciences with a deliberate plural

    because of the diverse theoretical and methodological

    framework scholars in different areas follow in theirgeographical practices; and the US National Science

    Foundation established a new program funding projects

    focused on coupling natural and human system dynamics

    (http://www.nsf.gov/funding/pgm_summ.jsp?pims_id

    13681); such mandates accelerate synthetic efforts and

    practices of hybrid geographies.
