institutions visibility: a study of UK HEIs social media use vs.
organizational characteristics
2. Higher education institutions are increasingly using social
media platforms as tools to communicate to prospective and current
students, alumni and society at large
3. Why online visibility matters?
4. Core organizational attributes matter in explaining online
communication; where status, reputation and size are important
predictors of hyperlink connections and centrality (Seeber et al.
2012, Lepori et al. 2013).
5. Is online visibility affected by social media use or by
other organizational characteristics? What is the relative
contribution of organizational characteristics and social media use
in explaining social media visibility (n of followers on
twitter)?
6. We investigate to what extent the number of twitter
followers is predicted by the use of Twitter and by the
organizational characteristics of the Higher Education Institutions
(HEIs) in the UK.
7. Social media visibility can be explained by: Hypothesis 1:
the social media use of the organization Hypothesis 2: a HEIs
organizational characteristics related to organizational size,
status and reputation Hypothesis 3: both the HEIs social media use
and organizational characteristics Hypotheses
8. Data about 137 UK HEIs *European Micro Data dataset (Eumida)
- a database containing the structural characteristics of 2,457
Higher Education institutions in twenty-eight European countries
(Bonaccorsi et al. 2010; Eumida 2009). * 1 2
9. Collected from Twitter profiles Dependent: Social media
visibility (Twitter) Number of followers Total number of tweets
sent The number of users that the HEIs are following as a measure
of their activity Date of first tweet and also whether the HEIs use
Twitter to share general news or to reach out to students
specifically Measures (1/3)
10. Independent: Organizational characteristics (Owen- Smith
& Powell 2008): size of the university (number of staff units
and undergraduate students) reputation in the core activities of
research, measured through the scientific productivity and the
research intensity, and teaching, measured through the teaching
burden status, as measured through the relational centrality of the
university in the system Measures (2/3)
11. Control variables the discipline profile, as some
disciplines may attract more attention than others because of the
societal salience of the topics addressed the geographical context,
in terms of the urban centrality of the city where the university
is located. Measures (3/3)

13. Method: Negative binomial regression We find that HEIs
visibility on Twitter are only partly explained by social media use
and that organizational characteristics also play a role in
explaining the social media visibility of HEIs. There is also an
early-adopter (of social media) advantage. Results (1/6)
