Networks, Disrupted 2
Abstract
Longitudinal interorganizational relationships (IORs) in New Orleans are used to assess
the ways in which organizations employed information and communication technologies (ICTs)
to (re)connect to their social networks and with what impact regarding post-disruption capacity-
building. Findings reveal tensions in old and new media use and that using multiple media is an
organizing mechanism that improves rebuilding efficiency and effectiveness. Specifically, using
mixed media, more so than any one old or new media, facilitated bridging and bonding social
capital to expand network capacity. An Organizational Media Spectrum model integrates media
intimacy, familiarity, and network capacity to illustrate the relationship between media strategies
and organizing processes for building capacity in social networks.

Networks, Disrupted: Media Use as an Organizing Mechanism for Rebuilding
As new information and communication technologies (ICT) emerge, established modes
are not necessarily replaced, however, tensions between the established and new media may arise
(Dimmick et al., 2011). The tensions between old and new technologies and their impacts on
communication patterns among individuals is an ongoing source of new media theorizing (c.f.,
Marvin, 1988). At the organization level, where evolving relationships are built and maintained
through collaborative endeavors, potential tensions and impacts on relationships are of similar
concern- organizational partners’ interdependence necessitates that ICT use be a shared and
social contract about how to stay in touch. In broader interorganizational relationships (IORs),
then, system-level patterns may be influenced by the established and new technologies, much
like tensions Marvin and others articulated when individuals’ social practices simultaneously
adopt and adapt with ICTs.
One way tensions get amplified is during network disruptions. In the time immediately
following the 911 attacks in the US, for example, mobile phone use became a source for
accessing information when other ICTs failed (Katz and Rice, 2002). Similarly, following the US
Gulf coast’s Hurricane Katrina, texting emerged as a source of information sharing when voice-
based technologies failed (Doerfel et al., 2010). Layered on top of reaching out through various
ICTs to gain information and support during such urgencies, individuals reach out to their strong
ties and familial relationships for various forms of support and usually use rich media like
phones to do so (Ling, 2008). This tension between media and an interdependent system within
which new and old media coexist has the potential to impact social patterns. This study considers
new and old media use as part of IORs and the media strategies organizations use to (re)connect
to their social networks after routines were disrupted by Hurricane Katrina.

When it comes to new technologies, communicating partners jointly negotiate the
adaptability of the technologies to maintain relationships (Dunbar-Hester, 2009). Moreover,
technologies range in terms of their utility, given unique context-based factors (Bouwman and
Van De Wijngaert, 2002; Dimmick et al., 2011). For example, in post-hurricane conditions,
widespread power outages make land-based computer use futile. Regardless of routine and non-
routine contexts, organizations have adapted communication strategies to integrate new media,
yet in interorganizational domains, the efficacy of new media in maintaining and
expanding/building social networks is largely ignored. For example, one valuable aspect of an
organization’s communications management is its collaborations with other organizations (Berry
et al., 2004; Taylor & Doerfel, 2011). Being engaged in broader community relationships and
with other organizations facilitates capacity building, which provides a form of necessary
infrastructure (Kent and Taylor, 2002). One way to build and manage such relationships is
through conventional networking practices (e.g., attend professional conferences) but new
technologies allow for adapting organization-level networking, so long as partners jointly adopt
alternative forms of staying in touch. Aside from descriptions of how organizations use social
media (e.g., Perry et al., 2003), little is known about old and new media uses to build and
manage interorganizational networks.
Despite the growing popularity of ICTs in general, and interests in how ICTs are adopted
and adapted by individuals, only a handful of studies explore organizations’ ICT use to build and
maintain relationships (e.g., Bortree and Seltzer, 2009; Kent, 2008). They emphasize the
increasing importance of social media channels in public relations (PR) and provide insight into
building relationships using social media (e.g., Briones et al., 2011). New media, however, have
been portrayed in contradictory ways in the literature (Rice, 1999; Wellman et al., 1996). They
Networks, Disrupted 5
are seen as decreasing social involvement or as integrative, connecting disparate others (Constant
et al., 1996) and consolidating existing connections (Lind and Zmud, 1995). The next section
considers these oppositional views.
New Media and Relationship Management
In terms of building and maintaining individual-level networks, Ellison, Steinfeld, and
Lampe (2007) reported that college students who use social networking sites build social capital
by enabling people to maintain and form new friendships. Online communication can also
promote face-to-face contact (Bargh and McKenna, 2004). More broadly, Internet use can
overcome contextual neighborhood effects in concentrated disadvantaged areas that would
otherwise limit opportunities for local tie formation (Hampton, 2010). A growing body of
evidence shows that new media helps individuals maintain relationships over geographic
distances (Boase et al., 2006; Van Den Berg et al., 2012) enhance social capital, or access those
resources (friendship, information) that are embedded in face-to-face and mediated social
networks (Dutta-Bergman, 2004; Lin and Erickson, 2008).
Drawbacks regarding social media use include a decline in offline interpersonal
relationships (Nie, 2001; Tillema and Schwanen, 2010) and weakened existing social ties with
family and friends from the loss of face-to-face contact (Putnam, 2000). Losing face-to-face
contact echoes the underlying point of media richness theory, which asserts that media range in
terms of the robustness of information that the media carries (Daft and Lengel, 1984). Channels
range from lean to rich, where equivocality of information is of greater concern at the lean end.
For example, a bulletin leaves no room for clarity compared with channels like telephones and
face-to-face, the foundation of Kraus et al. and Putnam’s views of friendship. From this view,
lean media are not ideal for uncertainty reduction. In terms of general media use, most people
Networks, Disrupted 6
employ mobile phones to keep in contact with fewer than six strong ties (Ling, 2008) which may
reduce the need to maintain larger and more diverse networks (Gergen, 2008). We discuss
individual uses of ICTs and media richness theory briefly since some practices and outcomes
involve individuals who network on behalf of their organizations and lean and rich channels
support information sharing differently (Daft et al.).
At the organization-level, the ways specific communication modes are used to stay in
touch with their networks is less researched, although IORs and building capacity in
interorganizational networks are emerging as essential components for an organization’s
communication strategy (Taylor & Doerfel, 2003; Kent and Taylor, 2002). Capacity building
refers to the strengthening of existing and expanding to new relationships in order to manage
uncertainty in the broader IORs and stakeholder environments. Such a view of PR is embedded
in systems theory (Broom et al., 1997), and it is because organizations need others for resources,
specialized services and expertise, and through coexistence in a competitive field that
organizations include IORs as part of their capacity building tactics (Van De Ven, 1976; Van De
Ven and Walker, 1984). The Internet provides an opportunity to create IORs through dialogic
components allowing input by and communication with publics (Kent and Taylor, 2002). Not all
organizations, however, use the Internet in a dialogic manner (Bortree and Seltzer, 2009; Taylor,
Kent and White, 2001), despite arguments that blogs offer more opportunities than traditional
Web sites for two-way dialog for organizations (Seltzer and Mitrook, 2007). Use of various
media is a way organizations can manage their interdependent relationships across the broader
system.
In his recent study, Kent (2008) focused on relationship building and proposed that blogs
provide organizations benefits such as “issue framing, relationship building, fostering trust, and
Networks, Disrupted 7
identification” (p. 37). In terms of the media relations function of PR, Waters et al., (2010)
discovered “media catching,” where organizations are contacted by journalists as a result of the
journalists following the organizations’ social media, as opposed to the conventions of
practitioners reaching out to journalists. While Waters et al. suggest new media are a way for
organizations to be available for adding new network relationships, Howard’s (2002) view
asserts that new media do not enhance network centrality so much as the additional media
choices facilitate access to one’s network. Howard’s thesis complements Kent’s view that
organizations use new media to enhance relationship quality.
Practitioners believe social media enable organizations to respond quickly to questions
and concerns from their publics and help them build relationships with strategic publics (Wright
and Hinson, 2008). This suggests relationship building opportunities, but Eyrich, Padman, and
Sweetser (2008) found that among 18 social media tools only about six tools are used and that
professionals are more inclined to use more traditional tools (e.g, email) as opposed to more
technologically complicated channels (e.g., text messaging, social networking sites). Similarly,
organizations have yet to fully adopt new technologies (e.g., blogs) for professional use (Porter,
Sweetser, and Chung, 2009). These findings echo the assertion made above, that new media do
not necessarily supplant old media, although tensions may arise. In this case, simultaneous uses
of old and new media may put pressure on organizations to adapt their ICT repertoires.
In short, research on organizations’ ICT use to maintain and build relationships is
generally limited to PR functions in terms of outreach. One notable driver beyond merely a PR
function is when external factors driven by resource needs result in adopting social media (Nah
and Saxton, 2012). Related, disasters put stress on systems in terms of creating uncertainty,
emotional distress, and financial loss. Like individual victims, organizations need resources and
Networks, Disrupted 8
support to manage the increase in these stressors and to facilitate recovery. Support ranges from
intangibles like information and emotional support to material support like loans and financial
gifts. Tapping into one’s network is a way of gleaning critical resources that support survival and
recovery. Indeed, after disaster, some have found such material support flows through networks
and is not just given to strangers (Doerfel et al., 2010; Murphy, 2007). Thus, in disaster contexts,
when there is a spike in the need for organizations to access a host of resources and when
mandatory evacuations and land-based communications thwart conventional access (e.g., face-
to-face; phone) to social networks, new media and innovative uses of accessible media are ways
in which organizations may negotiate system constraints to (re)connect. We consider the ways
organizations use established media (e.g., email, phone) versus more modern options reflective
of relatively unfamiliar media (e.g., in 2005, text messages and blogs were unfamiliar and thus
considered complicated) to reconnect to and tap into organizations’ networks. We thus ask,
RQ1: How do disaster-struck organizations use ICTs to reconnect and tap needed
resources?
Given an interest in the use of ICTs to (re)connect to interorganizational networks, we next
consider organization and social network theory.
Interorganizational Relationships, Networks, and (Re)Connecting with ICTs
An underlying assumption of organizational media use is that these communication
strategies are a part of managing environmental uncertainty. Uncertainty management and,
relatedly, organizational survival in the broader environment is a function of internal
organizational capacity, interorganizational resource dependencies, and evolving practices that
remain effective over time (Hannan and Freeman, 1984). Simply put, some organizational
research grapples with the extent to which organizations select, change, and adapt their routines
Networks, Disrupted 9
and repertoires over time or are relatively stable and predictable. Scholars like March (1981)
suggest that organizations are constantly changing and adapt routines easily and creatively; yet
Hannan and Freeman assert that change is actually relative to organizational responses to
environmental conditions. “Slow” response to rapidly changing conditions suggests a high level
of structural inertia because the organization’s response or change necessitated by the conditions
does not keep up (Aldrich and Ruef, 2006). Assuming IORs are an important component of an
organization’s strategies to manage uncertainty, we next turn to social capital, which is about
being embedded in networks that facilitate access to various forms of resources.
Social capital, density, and diversity. The effective flow of communication across
organizational boundaries is critical for an organization to build relationships in a dynamic
(Hannan and Freeman, 1977) and specifically, a disaster environment (Doerfel et al., 2010,
2013). Social capital refers to the resources embedded in relationships and can vary in terms of
bridging and bonding forms. Bridging refers to accessing diverse information gained through
weak ties, while bonding refers to building up cohesion between communication partners that
have invested the time necessary for deep trust. Bridging and bonding social capital are
particularly salient in disaster contexts when both uncertainty and a need for trusted information
are high. Communicating with other organizations facilitates better decisions about how to
proceed to achieve their goals of restoring their functionality (Comfort, 1999; Runyan, 2006).
Inadequate communication patterns such as disjointed information flows inhibit social capital
with implications explained by network density and diversity.
Dense networks have been defined in terms of how many connections a focal
organization has relative to the total possible links (Hannan and Freeman, 1977). A common
assumption is that organizations embedded in dense networks have high levels of social capital
Networks, Disrupted 10
(Brown and Ashman, 1996). Salient to disaster contexts is that communities (at individual- and
organizational- level foci) with strong relationships (high density) function better in emergency
situations because of increased trust (Chewning et al., 2012; Doerfel et al., 2010; Kapucu, 2006).
Related, organizational density and diversity are facets of an organization’s and broader
community’s growth and survival (Saxton and Benson, 2005). One drawback of locally dense
networks, however, is whether there is time to build out diversity in the network, too.
Diverse social networks are created by heterogeneity as opposed to homogeneity. Diverse
interpersonal networks include a wider range of ethnicities, religion, age groups, and
professional backgrounds (Hampton, 2010). Organization-level diversity includes organizations
that represent various sectors, competitors, profit, nonprofit, and government entities, etc.
(Doerfel et al., 2010). Diverse networks are associated with a range of positive outcomes since
diverse resources flow through diverse networks. For example, nonprofit organizations benefit
from having corporate, government, and community-located IORs (Nah and Saxton, 2012;
Saxton and Benson, 2005). Diversity is thusly viewed as a direct measure of the resources
accessible through networks (Lin and Erickson, 2008). Similar to advantages of high density, the
potential for social capital is maximized in social settings where the diversity of others is highest.
In terms of building social capital through dense and diverse networks, ICTs have their
merits, but face-to-face communication cannot be ignored. Public places such as public parks,
voluntary associations, and professional clubs which allow access to people from different social
groups are most likely to provide exposure to diversity (Lofland, 1998). Participation in these
types of venues are defined by face-to-face communication and the various spaces would have a
greater potential to support diverse networks. Other than face-to-face communication,
technologies that afford interaction with large numbers of others are likely to have direct effects
Networks, Disrupted 11
on network diversity (Hampton et al., 2010). These technologies include Internet use such as
web surfing and email and social-networking sites. Technologies which primarily afford
interaction with a small number of strong ties such as mobile phones, however, are likely to have
no relationship to diversity (Ling, 2008). For example, bloggers are likely to be very similar
(Adamic and Glance, 2005), but they may be more likely to participate in a variety of activities
to feed their blogs (Marlow, 2005). Despite the modes of connection, face-to-face and ICTs
impact network density and diversity. Yet in the context of disaster, access to social networks is
often difficult, even if possible, both on- and off-line.
In terms of network theory, density and diversity are a source of tension. On one hand,
bonding social capital (i.e., dense networks) implies exchanges of favors that provide mutual
benefits, building trust, and positive reputations in the broader community (Taylor & Doerfel,
2003). In this way, the network emerges as stable and predictable because of institutionalized ties
among a set of reliable, known partners (Hannan and Freeman, 1984). On the other hand,
bridging social capital (diversity) affords unique access because diverse ties suggest
complementary information and resources. Yet driving more diverse networks are relationships
that are weaker in terms of familiarity and frequency of contact. Indeed, Hales (2002) and
Hannan and Freeman (1984) suggest that organizations can undermine the advantages of loose
structures and networked forms by routinizing partnerships which can result in something similar
to a stable, rigid bureaucracy. Over time, what could be a dynamic network instead becomes
relatively inert, taking on an institutional quality. Simply put, organizations returning to the
same, familiar ties build network stability but with a finite and known knowledge set.
On the other hand, organizations that turn to weak or unknown ties take risks when the
relatively unfamiliar partner fails to deliver (Vangen and Huxham, 2003). But new partners
Networks, Disrupted 12
might offer unique solutions and plausible alternatives for an organization suffering the impacts
of a disaster. So a tension arises in that organizations partner with reliable, trusted others but also
network to build out access to unique information and resources vis-à-vis diverse ties. As an
added complication for the disaster-struck organization, the network is an important resource, but
accessing it over physical distances due to evacuation and downed communications
infrastructures can be difficult.
Communicating after network disruptions. When actors in dispersed locations require
immediate access to each other, they must overcome the constraints of traditional
communication (Dutta-Bergman, 2004; Rice, 1999). Some have asserted that the implementation
of new technologies in emergency management should improve communication speed and
quality in response operations (Comfort, 1999; Quaratelli, 1997). ICT use, however, may only be
as good as the intact network. Kapucu (2006) explored the contribution of ICTs to
communication among first responders during September 11, 2001 and found that building up a
strong interorganizational network before disaster facilitates the ability to take advantage of
ICTs. These arguments, along with organization theorists’ arguments discussed above, suggest
that a multi-pronged ICT strategy would give organizations an edge in reconnecting to their
disrupted networks.
These assertions rest on the underlying assumption that IORs rely on and are more
swiftly reconnected using ICTs. Indeed, this argument underscores the key components argued in
this paper. Strategic communication involves IORs that give access to information flows, dense
and diverse networks, and a host of communication channels through which connections are
made and retained. Strong relationships marked by dense networks and weak ties that access
diverse networks build up social capital that can be mobilized after disaster (Doerfel et al., 2010,
Networks, Disrupted 13
2013). The ability to reach those networks through ICTs means swift access to partners,
resources, and information necessary to the victimized organization. But the underlying
presumption remains largely untested in the IOR context, so we ask:
RQ2: How do ICTs facilitate the rebuilding of disrupted networks?
Method
Open-ended interviews were conducted with organizational leaders using convenience
and snowball sampling. Recruiting included 16 field visits resulting in 90 interviews with 56
leaders. For this research, interviews from a first wave of data collection were used. Participants
represented New Orleans industries including restaurants/bars, media, non-profit agencies,
cultural venues, banks, professional firms and retail establishments. Because structured
communication channels may not work in emergencies, boundary spanners can play a significant
role in effective communication in emergency and crisis management. Boundary spanners are
organizational members who link their organization with the external environment. We thus
asked participants to be informants as organizational boundary spanners. In their leadership role
they were privy to critical decision making regarding rebuilding. Included were small (less than
20 employees), medium (21-100 employees), and large entities (more than 100 employees).
Interviews ranged from 21-105 minutes and were conducted in person and by telephone, with no
significant differences between face-to-face (n=39; M =53.82, SD=17.65 minutes) versus
telephone (n=17; M=54.29, SD=15.77 minutes).
As part of the larger research project, over 1,500 pages of interviews were assessed over
a two-year period by a team of seven coders using AtlasTi, a data analysis program that allows
for review of data in a variety of ways, including as a whole document, by code, or by quotation.
Codes were compared within and among documents, including by quantity, association with
Networks, Disrupted 14
other codes, and similarity and differences among stories. Among the resulting multi-page list of
codes and subcodes, this paper focuses on codes about communication media and network
measures of density and diversity1.
Variables
Media use. ICT media uses included face-to-face, landline phone, mobile texting, mobile
talking, e-mail, blog/website, phone, one way (e.g., mass communicated announcement that
would not enable feedback through the same medium). These media were then categorized,
reflective of the relative familiarity these modes had in 2005, during the disaster. For example,
some 200 million cell phone users (http://www.infoplease.com/ipa/A0933563.html) existed in
the United States in 2005 and underlying participants’ assumptions was the ubiquitous nature of
talking on mobile phones. For participants, however, texting was seen as new and innovative,
and staying in touch with blogs or 2-way websites was limited to those who reported “tech
savvy” employees or a penchant for new technologies.
Four categories emerged in terms of communication modes used: (a) established - face-
to-face communication and landlines, (b) common - mobile phone talking and email, (c)
innovative - mobile text and blog/website use, and (d) mixed - use of all communication media.
Each organization was assigned one of these categories based on frequency of use. For instance,
if a participant suggested face-to-face and landline dominated their organization’s use over any
other media then the organization was assigned to established. If all media were used at varying
degrees, with none dominating over others, then the organization was coded as mixed. Six were
assigned to established, 16 to Common, 6 to Innovative, 24 to Mixed and four lacked sufficient
information to be coded. Organizations generally had “pet” approaches reflective of these four
categories so two independent coders noted no discrepancies. To provide equally weighted
Networks, Disrupted 15
samples for the analyses, all six of the organizations coded in the established and innovative
categories and subsamples of six sets of observations for density and diversity were randomly
selected from the 16 Common and 24 Mixed categories. Analyses were repeated with different
randomly selected subsamples of Common and Mixed to ensure that each network was included
in the analysis and that results remained consistent across different subsamples.
Phases over time. To capture longitudinality, ATLAS.ti queries were made for codes
representing timing of contact. Phases spanned from before the storm, while evacuated,
immediately after returning, to settled-in, marked by a stable routine of work. Although
interviews were based on recall, research shows that “salient events are more likely to be recalled
than nonsalient events, where saliency is a function of the unusualness of an event, its economic
and social costs and benefits, and its continuing consequences” (Pearson, Ross, and Dawes,
1992, p. 88)2.
Network ties. To capture all salient alters (with whom an organization reports having
links) named by organizational leaders, ATLAS.ti queries were used to search for discussions
about sources of emotional, informational, and financial support and that such a contact was for
professional reasons and was deemed useful3.
Alter type. An alter refers to another organization named by a participating organization.
When an alter was named, that unique alter (an organization, the organization of the individual
named when the individual represented the organization, or an individual) was categorized using
one of 49 codes so that across-case comparisons could be made. Each organization represented
was assigned its own row, populated by the number of times a particular organizational type was
named for each of the four over time phases. The total number of links identified by all
participants was 9234 ranging from a low of 3 (the participating organization was relatively
Networks, Disrupted 16
isolated) to a high of 49 (the participating organization’s network was relatively connected)
(m=24.7, SD=9.1). Organizations discussed in a negative light (e.g., ineffective) or identified but
not reachable were assigned a value of zero. Each row’s cells for each of the four over time
phases were divided by the total number of alters named by ego, across all points in time. A
resulting 2-mode (n x m) matrix represents the organizations’ reported alter ties. Matrices are
valued, rectangular, and represent the extent to which ego, n, named alter types, m, as links used
at the four stages. Four n x m networks (one for each point in time) were constructed and these
matrices were used to extract sub-matrices to represent the variables density and diversity.
Density. Density indicates information flows and in its simplest form, is a proportion of
actual links divided by total possible links. Row totals from the “Alter Type” matrices described
above were used to calculate density for each participating organization. In those matrices, cells
were proportional values of connections each participant reported having relative to their total
connections over the four phases of time. Each valued cell is a percentage of an organization’s
links relative to the total alter organizations named by that organization across all points in time.
Density values ranged from .32-1.0 (m=.64, SD=.18) before the storm (T1), 0-1.0 (m=.37,
SD=.24) while evacuated (T2), 0-1.0 (m=.49, SD=.25) immediately after returning (T3), and .16-
1 (m=.63, SD=.20) in the settled in-stage (T4). Some businesses whose density contracted
included restaurants and tourism companies; some whose density expanded included
professional firms and media companies.
Diversity. Diversity accounts for the number of organizations identified from different
sectors than the participating organization’s sector, and ranges from 2-17 (m=6.57, SD=2.59)
before the storm (T1), from 0-9 (m=4.48, SD=2.29) while evacuated (T2), from 0-11 (m=5.64,
SD=2.63) immediately after the storm (T3), and from 1-14 (m=6.5, SD=2.7) in the settled-in
Networks, Disrupted 17
stage (T4). Examples of organizations whose diversity contracted were restaurants and tourism
while some professional firms and media companies’ expanded.
Results
RQ1 asked about how disaster-struck organizations use ICTs to reconnect and tap into
needed resources. Based on the interview data 27% of all organizations used face-to-face
communication, 19% used blog/website, 15% used email, 11% used mobile phone, 5% used
landline, and 4% used mobile texting to connect with their networks. Overall, established media
was predominant. Additional queries assessed how organizations used the various media
categories. More interpersonal modes of communication (i.e., face-to-face, talking on the phone)
were used for connecting with other organizations and sources of support. Websites and blogs
were used more passively in terms of information gathering (e.g., one named alter began a blog
to post information, much like a bulletin board). Texting was “discovered” by some but several
participants noted the challenge with texting- it worked, but oftentimes their interlocutor did not
know how to use it. Thus, tensions on social patterns related to old and new media
simultaneously existing but not necessarily adopted and/or adapted could be ascribed.
RQ2 asked how ICTs facilitate the rebuilding of disrupted networks. We used factorial
repeated-measures ANOVA to test the relationship between scores of the same subjects at
different time points. We tested if the variances of the differences between conditions are equal
using Mauchly’s test. The first set of analyses includes within-subject, between-subject, and
contrasts to understand the relationship between density and media use. The results of within-
subject effects show that density was significantly affected by the disaster phase, F (2.15, 43.20)
= 29.06, p = .00 (Table 1). In other words, there is a significant difference in interorganizational
densities between some phases of the disaster. Table 2 shows the pairwise comparisons for the
Networks, Disrupted 18
main effect of the disaster phase corrected using a Bonferroni adjustment. This table indicates
significant differences between T2 and T1, T3, T4 meaning that there was a significant drop in
density when the Katrina hit and an increase in density during the disaster periods immediately
following the storm (T3 and T4). Figure 1 illustrates the changes in density over the four disaster
phases. Regardless of the communication media used, density decreased during the disaster,
started increasing at varying degrees after the disaster, and the original density levels were
maintained or improved at the end of the two-year period.
Second, between-subjects analysis was tested to understand if media use had any effect
on the density across the four disaster phases. There was a significant effect of media type on the
density over time, F (3, 20) = 1.63, p = .03. That is, type of frequently used media affected
density. To break down this interaction, contrasts were performed comparing all disaster phases
and media categories (Table 2). Contrasts revealed significant interactions when comparing
phases 1and 2 and phases 3 and 4. Figure 1 shows the density of established and mixed media
users have similar patterns as well as similar rates of change over time, and show different
patterns and rates of change than common and innovative media users.
The second set of analyses including within-subject, between-subject, and contrasts were
done to understand the relationship between diversity and media use. Within-subject effects
show that diversity was significantly affected by the disaster phase, F (2.35, 47.06) = 13.67, p =
.00 (Table 3). That is, there is a significant difference in diversity between some phases of the
disaster- there was a significant drop in diversity from pre-Katrina to during Katrina periods and
a major increase in diversity as organizations returned to a settled-in state. Diversity changed
similarly to patterns observed for density, except diversity differed prior to and after the disaster.
In other words, organizations’ original network before the disaster changed significantly after the
Networks, Disrupted 19
disaster; they built new diverse relationships. Figure 2 illustrates these changes. Regardless of
the communication media used, diversity decreased during the disaster, started increasing after
the disaster, and significantly changed by the settled-in phase. Specifically, users of established
and the mixed-media modes (re)built their diversity at a much faster rate and were also able to
diversify beyond pre-disaster levels compared to common and innovative users.
Table 4 shows the pairwise comparisons for the main effect of media use corrected using
a Bonferroni adjustment. This table indicates that the main factor reflects a significant difference
between innovative and mixed modes. Innovative and mixed media allowed organizations to
build significantly different numbers of diverse relationships. Next, contrasts were performed
comparing all disaster phases and all media categories. Contrasts revealed significant interactions
when comparing right after Katrina and once settled in (Table 5).
Overall, data showed that networks broke up in terms of density during the disaster and
organizations that relied on established and mixed media to reconnect were more efficient at
rebuilding a network that was similarly dense prior to Katrina. These media users also (re)built
diverse networks at a faster rate and expanded diversity in the long run relative to pre-disaster
levels. Meanwhile, common and innovative media users’ (re)networking was slower and, in the
long run, these users’ networks were less dense and diverse. Based on qualitative aspects of the
data, innovative media users engaged the media for information seeking rather than relationship
building and ultimately did not experience growth in terms of density and diversity.
Discussion
This study identified old and new media use by organizations to (re)connect to disrupted
networks after Katrina and with what effect on social patterns. Results suggest considerations
about old and new media tensions as IORs get rebuilt. Although 2005 ICTs were different than
Networks, Disrupted 20
today, coding categories reflected two dimensions of ICTs that withstand the test of time- ones
that range in terms of rich interpersonal interaction and information-getting capacities (Daft and
Lengel, 1984), and those that are routinely used versus unfamiliar or new (Dimmick et al., 2011;
Marvin, 1988). Contributions regarding ICTs for networking and the dynamics of IORs are
discussed.
The Media Spectrum and Interorganizational Networking
Mediated communication channels are an option for organizations, but the ways in which
organizations use available ICTs have implications for their social networks in general and
rebuilding them, in particular. In general, organizations that used various media simultaneously
had higher levels of density and diversity and rebuilt and expanded their networks more swiftly.
Conversely, lean media meant slower (re)networking. These results demonstrate an additional
advantage to Kent and colleagues’ (2008) advocating for organizations to use modern media in
their strategies to manage their environments. The mixed use of media served as a rebuilding
catalyst. The combined use of rich and lean with old and new media channels was fundamental
to reconnecting and drawing on social capital. And with mixed media, organizations
accomplished this more efficiently and effectively. These analyses complement Dutta-Bergman’s
(2004) findings about individuals’ channel complementarity after 911. Face-to-face interactions
and phone calls remain a necessary component to IORs after disaster. Yet, in the ever-evolving
new media landscape, organizations that use face-to-face, as well as a mix of new media reap the
benefits tied to diversity, density, and in a more efficient manner than those who use solely
established, rich media. These findings also extend the thesis that tensions amid old and new
media used together may impact social patterns in unique ways (Marvin, 1988).
Networks, Disrupted 21
The data inform the ways media and organizational theories work together and are
illustrated in the Organizational Media Spectrum depicted in Figure 3. The first dimension
reflects the intimacy levels ranging from interpersonal-to-public nature of communication over
mediated channels. The second dimension categorizes the channels as ones ranging from very
familiar (known) and thus conventional to unfamiliar/new. Also depicted in the figure are rich
and lean media coupled with bonding (density) and bridging (diversity) social capital. Density is
more commonly built up in face-to-face interactions while social media enable capacity building
in terms of diversity (Bortree and Seltzer, 2009; Kent, 2008).
The overlap of the channels in Figure 3’s Venn diagram shows that face to face
communication is necessary, but integrating mediated forms of communication give
organizations the same edge without the presumed time involved to communicate solely through
rich media. In other words, the center circle in the media spectrum offers organizations an
efficient approach that is reflective of the more interpersonal part of relationship building.
Indeed, those organizations that did not integrate conventional media as prominently in their
networking suffered a delay in their return to pre-disaster networks and, for those relying solely
on innovative media, suffered a small setback in terms of density and diversity compared to their
pre-disaster levels. In short, organizations still relationship-build with other organizations using
more rich and conventional media choices. Future research can expand the Organizational Media
Spectrum model by considering new ICTs and their use with other channels to (re)build
networks at individual and organizational levels of analyses. As ICTs evolve, we propose that
ones that support more personal dynamics and swift networking will be more useful to IOR
building after network disruption, which ties in with theory about IOR management: Trust is an
Networks, Disrupted 22
important factor (Vangen and Huxham, 2003) and even more so in emergency contexts (Kapucu,
2006).
The Dynamics of Interorganizational Networks
Adaptive networking strategies support survival in an interdependent system (Broom et
al., 1997; Van De Ven, 1976; Van De Ven and Walker, 1984) that has experienced change due to
a major environmental jolt (Aldrich and Ruef, 2006; Hannan and Freeman, 1984). The disaster
was an event where, coupled with media choices, some organizations broke out of past routines
by not merely revitalizing old ties (a trend towards structural inertia), but by expanding and
enhancing their network, they enjoyed increased levels of social capital. After disaster, tensions
of density and diversity were evident. Organizations that used mixed media increased both
aspects of networking, a pattern likely reflective of the urgency and elevated needs for
information. They doubled-down on reaching out to both types of ties. This finding complements
Doerfel et al. (2010) who reported qualitative evidence that organizations found the disruption a
time that organizations deepened existing ties (bonding social capital) and expanded their
networks (bridging social capital). Given the growing body of disaster research, disaster is a time
when change, not structural inertia, occurs for some organizations. Whether this is by design or
necessity is unclear, though this study demonstrates the value of mixed media for facilitating
such change in networks.
Those organizations whose practices were with the common and innovative media that
tended to be at the public end of the Media Spectrum (Figure 3) returned to the same structural
qualities as before (Figures 2 and 3). Curiously, why would organizations that use new ICTs be
stuck in old organizing practices? The dimensions in Figure 3 amplify the discovery that their
media strategy lacks relationship building at the personal level. For organizations recovering
Networks, Disrupted 23
from a disaster, media presence is not sufficient. Disaster is an event that affords the opportunity
to break free from structural inertia through adaptation, but media strategies including a personal
dimension, drive that potential of the inert network to actively grow (diversity) and intensify
(density). Organizations should thus consider this theoretical advance in their disaster plans:
media is an organizing mechanism of survival. The communication function after disaster is not
simply about announcing a reopening, a return, or a reconnection. The communication plan is
about adapting with a media mix that supports revitalizing old and building new connections that
support social capital access and thus survival.
Limitations and Implications
These findings are not generalizable because the convenience sample included only
relatively successful organizations. Related, a small sample meant that subsamples had to be
used for balanced analyses, compromising effect size. These data, however, were based on a
highly salient event with data that offer unique insights into organizations and their
communicative actions for managing a fundamental rebuilding component to surviving the
disruption of their network: mediating interorganizational relationships. Organizational strategic
planners should resist the ease of ICTs, recognizing that on their own, they are not sufficient to
maintaining, rebuilding, or expanding social networks. On the other hand, relying solely on the
more interpersonal end of relationships misses “media catching” opportunities by not attending
to a broader reaching web presence (Waters et al., 2010) as well as expanding their networks.
Conclusion
This study considered social networks as one part of disaster management and how ICTs
play a role in mobilizing interorganizational social networks. The Media Spectrum (Figure 3)
illustrates results of the network tensions, relationship dimensions, and communication

technology familiarity. Organizations varied in their attempts and patterns of rebuilding showed
that ICTs are sufficient but more personal means were necessary for post-disaster rebuilding.
Extending organization theory to disaster, organizations using face-to-face and interpersonally
rich ICTs broke through an aspect of structural inertia with more dense and diverse networks in
the long run. By viewing the organizations’ challenges within the system of interdependent
relationships, this study also extended media theory in terms of the tensions old and new media
wrought during a time when adapting to new communication repertoires facilitated swifter
access to social capital and survival.

Figure 3. The Organizational Media Spectrum. Information and communication technologies
(ICTs) used to reconnect interorganizational networks are depicted in terms of (a)
Communication intimacy dimension, ranging from personal interactions to public
communication; (b) familiarity with communication technologies dimension ranging from types
that were coded as commonly known and used to those that were seen as new/unfamiliar; and (c)
a third dimension depicting network capacity and the tensions of density versus diversity.
Circumference size represents broader potential reach to others using ICTs. Communication
strategies that range from focused to diffused as well as necessary and sufficient conditions
observed in the data are noted with dotted lines and the size of the circles suggests relative
quantities of alters the focal organization could communicate with through the various ICT
approaches.
