AbstractAbstractOver the last five years within the UK, the Research Councils, the Department of Health and major charities such as the Wellcome Trust, have begun to address the need to build capacity in public health research and to ensure better mechanisms for translating evidence into practice. Following reports such as Public Health Sciences: Challenges and Opportunities, major new ventures such as the National Prevention Research Initiative, the creation of Public Health Research Centres of Excellence, and the new public health stream of the National Institute for Health Research, appear to have forged a common purpose to support “better research for better health” [1]. This study has capitalized on the occasion of the launch of one such Centre to describe the social networks of its stakeholders and investigate the nature and extent of the relationships between them.

ConclusionsConclusionsUsing results obtained from 98 respondents from 44 organizations and research clusters we have been able to assess the expectations, goals, and network connections of the respondents. Analysis of data on participant expectations and personal goals suggest that the academic members of the network were more likely to expect the work of the Centre to produce new knowledge as compared to non-academics, but less likely to expect the Centre to generate health interventions and influence health policy. Academics were also less strongly oriented than non-academics to knowledge transfer as a personal goal, though more confident that research findings would be diffused beyond the immediate network. A social network analysis of our data suggests that a central core of around 5 nodes is crucial to overall configuration of the regional public health network in Northern Ireland, and that whilst the overall network structure is fairly robust, the connections, between some component parts of the network - such as academics and the third sector - are unidirectional.

Block modellingBlock modellingBlock-modelling (or positional analysis) partitions the nodes into structurally equivalent or attribute based sets [6,7]. In mathematical terms, the adjacency matrix is rearranged to form a specified number of blocks, wherein each block contains nodes with the same attribute. The 193 organisations depicted in Figure 3 were organised according to their work sector, as were listed in Table 3.

Impact

Strength

Figure 5: A bubble chart of values attributed to impact and strength of collaboration. Both measures were rated from high (1) to low (3). A bubble chart is a two-dimensional scatter plot where a third variable is represented by the size of the points, in this case the frequency of choice. The coefficient of correlation between impact and strength is r = 0.5869. Therefore both are duly considered in Table 7.

Figure 4: Reduced block-model of network were nodes have been partitioned into structurally equivalent sets. The shape of the node is representative of the type of organisation (see caption to Figure 3). Node size corresponds to the number of organisations grouped together within each sector. Numbers close to each node indicate the number of nominations from one sector type toward another. Note that the network is unidirectional between academics and the third sector.

Background: The NI Health Care SystemBackground: The NI Health Care System

The NI health care system has gone under major reforms in the last few years. In November 2005, the Secretary of State for Northern Ireland announced a radical restructure of public administration structures within the province. The number of public bodies have been reduced significantly to make the public sector more streamlined and economically efficient. The impact on health and social care has been significant [2].

The details given below were correct at the time of the launch of the CoE in 2008, prior to the further reforms initiated on 1st April 2009.

of impact (x) and strength (y) that participants regarded their contact with organisations. Scale of 1(high) - 3 (low), as partitioned/blocked into sectors. RMSS range of strong (12+12) to (32+32). Entry (i : j) from row i and column j, gives the RMSS from block i to block j.

Those tran-sectoral connections with values missing may not be due to a lack of interaction, but rather a lack of data being collected at the CoE launch. For example, no For-Profit organisation responded to the questionnaire and hence there were no nominations from this to other sectors.

Network measuresNetwork measuresCentrality is a structural attribute of nodes in a network and is a measure of the contribution of network position to the importance, influence or prominence of an actor in a network. Centralisation is a network level measure which gives information regarding

the overall network structure.

CoE for Public Health (NI) NetworkCoE for Public Health (NI) Network

Initial work carried out included the creation, coding and analysis of a questionnaire on those who attended the launch of the UKCRC funded Centre of Excellence for Public Health (NI) [3]. This was to discern the potential placement of the CoE and the necessary role it could play within the local health sector. This involved obtaining the necessary information through questionnaires, of which 98 were returned. From the information given, a representation of the public health care sector within Northern Ireland was created and analysed. This involved the use of UCINET, Netdraw and SPSS software packages.

Figure 3: Network of 193 organisations and research clusters as named by attendees at launch. The shape of a node is representative of the type of organisation: = Statutory Public Health Delivery (53); = Policy-making, standard setting and professionals (37); = Third Sector (27); = Academic (60); = Commissioners of research (11); = For-Profit (4); and + = Primary Care (1). The colour of the nodes is then an indication as to whether that organisation was present at the symposium (blue if present, grey if not) and whether it has representation within the CoE (red). Lastly, the colour of the ties (edges) is an indicator of whether the relation is reciprocated or not. The red dashed ties denote reciprocated nominations (e.g. A B) whilst black solid ties are one-way nominations, where an organisation has named another but not vice versa (e.g. AB and A B).

Table 3: Profile of participants of the questionnaire. 59 respondents were from the academic sector reflecting the composition of the CoE centred in the University, and will be

reflected in the network structures.

Table 4: How academic and non-academic participants personal goals relate to those of the UKCRC Northern Ireland Centre of Excellence in Public Health Research, with a chi-square test performed to see if these were the same. Note that non-academics’ goals are more strongly aligned with ‘Knowledge brokerage’ when compared to those of the academics (p-value = 0.002).
