“…Many approaches to analyzing two mode networks consist of converting the data to a one-mode network (either MxM or NxN) that is a projection of the original data. However, previous studies have shown that one-mode projections subvert many of the reasons for collecting the two-mode data structures in the first place, lose information, and can present misleading results (Borgatti and Everett 1997;Jasny 2012;Latapy et al 2008;Opsahl 2011). …”

Gould and Fernandez (1989) developed a widely used operationalization of brokerage for onemode networks. The basic idea of brokerage is that the central actor or 'broker' benefits from spanning the gap (or structural hole) between two disconnected parties. However, it is not always advantageous to limit the systems studied to only one mode. We develop an operationalization of two-mode brokerage in which we can classify the structures according the heterogeneity of the types of actors involved. We apply this conception to water policy networks in the San Joaquin-Sacramento River Delta in California where two-mode networks represent organizations participating in multiple policy institutions. The potential benefits of brokerage are high in these types of fragmented systems where multiple institutions and organizations are involved with policy decisions. Of particular interest is the role of collaborative institutions, which are hypothesized to broker the most heterogeneous structures. We use our two-mode version of brokerage to construct a scale of brokerage from most homogeneous to most heterogeneous. This scale lets us categorize both the role of these collaborative institutions as well as the importance of brokerage in the system overall.

“…Thus, converting to a one-mode network is not appropriate in this case, and tie data are analysed using the two-mode relations. Analysing two-mode network data requires some modification of typical graph measures for one-mode data, as some information may be lost in projecting from two-mode to one-mode (Borgatti and Everett 1997, Latapy et al 2008, Borgatti and Halgin 2011, Vernet et al 2014). In the current analysis, the network will be analysed as two-mode, using standard measures of two-mode centrality .…”

This article contributes to the literature on the European border security industry with a network analysis of a new bipartite data set. The network is composed of speakers and their speech topics at a European border security conference taking place from 2008 to 2015. Speakers are linked to conferences by year of attendance and to speech topics to identify key actors and discourses using measures of centrality. A multiple regression quadratic assignment procedure (MR-QAP) is used to explain the continuity of conference speech topics. The centrality analysis reveals a number of "hubs" and the discourse analysis reveals a consistent focus on social control and surveillance over human rights. The MR-QAP regression suggests that shared discourses are driven by organisations which act as key speakers at many events, and whose discourses are prioritised over those of other actors. The article concludes with notes on the critical implications of the findings. ARTICLE HISTORY

ResumoAs redes de dois modos compreendem as ligações entre dois conjuntos distintos de entidades; o termo "modo" refere-se a categorias específicas de entidades. Rede de um modo se caracteriza quando membros de uma rede têm ligações com outros membros da mesma categoria -como uma rede de pesquisadores -, e rede de dois modos se caracteriza quando seus membros possuem ligações com atores de outras categorias. A rede de dois modos é representada pela interação entre atores e entidades sociais como um único sistema social, como, por exemplo, as ligações entre pesquisadores e instituições (dois conjuntos de atores) em uma mesma rede. O objetivo deste artigo é conceituar e apresentar as redes de dois modos, que são empregadas nos estudos que utilizam a metodologia Análise de Redes Sociais. Por meio da análise da literatura, selecionaram--se artigos que enfatizam aspectos conceituais das redes sociais de dois modos, o que permitiu descrever e destacar exemplos e aplicações desse tipo de rede. No Brasil ainda são poucos os estudos publicados que mencionam ou empregam aplicações de Análise de Rede Sociais de dois modos. Com essa ênfase, este artigo contribui para disseminar aplicações de redes de dois modos.Palavras-chave: Análise de redes sociais. Redes de afiliação. Redes sociais. Redes sociais de dois modos. Abstract Two-mode networks consist of connections between two distinct sets of entities. The term "mode" refers to specific categories of entities. The term one-mode networks is used when members of a network are connected with other members in the same category -as a network of researchers -and the term two-mode network is used when members are connected with actors from other categories. The two-mode network is represented by the interaction among actors and social entities as a single social system, such as the connections between researchers and institutions (two sets of actors
