                  Abstract
                  This paper outlines an index of LGBT+ inclusion for Universities. The index has a twofold
                  aim: to help tertiary education institutions to assess their degree of inclusiveness, and to detect
                  the level of LGBT+ inclusion in tertiary education. Starting from the existing LGBT+ inclusion
                  indices like the Campus Pride Index and LGBT+ Inclusive Education Index, the LGBT+
                  inclusive university index refers to an extended set of indicators and is based on Fuzzy rule-
                  based systems of the Mamdani-Assilian type to measure inclusiveness.
                  Best practices in LGBTI+ inclusion, implemented by Italian universities and identified in this
                  study, are highlighted with the aim of suggesting and recommending guidelines helpful to
                  fighting homo-bi-transphobic discrimination in higher education institutions.

1. Introduction
    This paper investigates the capacity of universities to favour LGBT+ inclusion in academic life and
is intended to contribute to the growing literature on the evaluation of the degree of inclusiveness of
higher education institutions. Evaluating the degree of LGBTQI+ inclusion can also contribute to
strengthening diversity in tertiary education institutions with multifaceted benefits on the learning
environment, the students’ learning experience and the prevention of stereotypes, cultural awareness
and political participation with positive spillover effects on society [1][2].
    In order to measure LGBT+ inclusion, we selected a set of indicators and elaborated a model by
using fuzzy rule-based systems of the Mamdani-Assilian type [3][4] that will allow each university to
assess its degree of LGBT+ inclusiveness. We then applied the model to measure the degree of LGBT+
inclusion of Italian universities. The choice of Italian universities is related both to their long historical
tradition and their established place in the cultural life of the country (see e.g. the University of Bologna,
founded in the eleventh century) and to the recent implementation of policies to enhance LGBT+
inclusion. Moreover, the Italian system is based mainly on public Universities, and University rankings
have been published in the media for many years. However, in University rankings the LGBT+
inclusion dimension is overlooked.
       To fill this gap, we carried out a survey of the 58 Italian public universities to identify the
practices implemented to facilitate LGBT+ inclusion. The survey was carried out in March and April
2019 collecting the indicators to measure LGBT+ inclusiveness in universities with the support of six
LGBT+ (or allied) student unions and in line with other relevant LGBT+ inclusion indices: Campus
Pride Index and LGBT+ Inclusive Education Index [5][6][7]. The response rate was 100 per cent and

data-processing started in May 2019. Fuzzy rule-based systems of the Mamdani-Assilian type [3][4]
were adopted to develop the LGBT+ Inclusive University Index and to construct the first national
ranking of public universities with regards to the level of LGBT+ inclusion. Finally, best practices in
terms of the inclusion of sexual minorities, implemented by Italian universities and identified in this
study, will be highlighted with the aim of suggesting and recommending guidelines to counter
homotransphobic behaviour.

2. The fuzzy rule-based system
    Fuzzy rule-based systems of the Mamdani-Assilian type [3] [4] were adopted to develop the LGBT+
Inclusive University Index and to draw up the first national ranking of public universities relating to the
level of LGBT+ inclusion. The system identifies the fuzzy logic inference flow from the input variables
to the output variables. The fuzzification in the input interfaces translates crisp inputs into fuzzy values.
The fuzzy inference takes place in rule blocks that contain the linguistic control rules. The outputs of
these rule blocks are linguistic variables. The final defuzzification in the output translates fuzzy
variables into crisp numbers. Figure 1 shows the structure of the fuzzy rule-based system including the
input interface, the rule blocks and the output interface. The connecting lines symbolise the data flow.

   The data used in the analysis is a questionnaire consisting of 14 questions relating to two main issues:
the context and the Alias Career in each university in the academic year 2018-2019. The survey of the
Equal Opportunities Bodies of 58 Italian public universities was carried out in March-April 2019. The
questions in the survey were answered on a scale from 1 to 4, with 1 corresponding to the minimum
level of inclusion and 4 to the maximum, to enable respondents to easily understand the ordinal scale.
We defined the Base Variable Range of our initial inputs with values from 1 to 4. The only exception
was for the Bathrooms and Crime Reporting variables that are defined on a scale of 0-1, representing
non-availability or availability, respectively. Linguistic variables are used to translate real values into
linguistic values.
     All the inputs (with the exception of Bathrooms and Crime Reporting variables that are
dichotomous) are described by three linguistic attributes: low, medium, high. Each input variable of the
fuzzy rule-based system is described by three triangular fuzzy numbers representing the values low,
medium and high. On a scale from 1 to 4 we chose the low triangular fuzzy number to be represented
by the triplet (1, 1, 2.5), the medium triangular fuzzy number to be represented by the triplet (1, 2.5, 4),
and the high triangular fuzzy number to be represented by the triplet (2.5, 4, 4). It is important to point
out that these values are useful for determining the membership values (ranging from 0 to 1) of each
input in our fuzzy system. Answers are coded in an equidistant way on the membership scale (0, 1/2,
2/3, 1) and represents a similar improvement in the criterion. The individual answers are designed in
such a way as to contribute to marginal improvement in the same way and are able to generate weights
in a transparent manner. Whenever we go up one step in the scale we also go up one step in the criterion
improvement. Moreover, when one variable is improved by one step, the final ranking of the University
improves. The initial values 1, 2, 3, 4 are never used in the system. The cardinal scale used provides for
the same distance among the elements.
  For the binary variables Bathrooms and Crime Reporting:
If they are not present then the membership degree is 1 in “false” and 0 in “true” i.e. “not present” is
associated with the vector (1, 0);
If they are present then the membership degree is 0 in “false” and 1 in “true” i.e. “present” is associated
with the vector (0, 1).
    The first level of intermediate variables is described by five linguistic attributes: low, medium_low,
medium, medium_high, high. The second level of intermediate variables is described by seven linguistic
attributes: very_low, low, medium_low, medium, medium_high, high, very_high. The LGBT+
University Inclusion Index is described by nine linguistic attributes.
     The rule blocks contain the control strategy of a fuzzy rule-based system. The 'if' part of the rule
describes the situation for which the rules are designed. The 'then' part of the rule describes the response
of the fuzzy system in this situation. The degree of support (DoS) is used to weight each rule according
to its importance.
    The processing of the rules starts with calculating the 'if' part. The operator type of the rule block
determines which method is used. We choose the MIN operator of aggregation for the 'if' part and the
MAX operator of aggregation for the 'then' part to enable all firing rules to be evaluated. Furthermore,
we adopt the Centre of Maximum (CoM) method for the defuzzification, resulting in the ‘best
compromise’ method.

3. Results
    We applied our Fuzzy rule-based systems of the Mamdani-Assilian type [3][4] to 58 Italian public
universities. In Table 1 we report the final ranking. For each University, we also show the evaluation
of the two intermediate outputs (Context and Alias Career) and on each intermediate variable (Services,
Education and Involvement for the Context dimension and Students’ Alias Career and Employees Alias
Career for the Alias Career dimension. In this way, each dimension and intermediate output can be
evaluated. The last column shows the LGBT+ University Inclusion Index ranking.
    We are aware of the need to be careful in the interpretation of the results of the multi-layer fuzzy
rule-based system. Given the lack of mathematical results on monotonicity for hierarchical models, we
follow as far as possible the guidelines for non-hierarchical models (such as verifying the smoothness
and the monotonicity of the fuzzy rule-based system). However, our findings are consistent with our
experiential knowledge of the national university scenario.
    The last five universities in Table 1, highlighted in red, are those that do not have any protection for
LGBT+ inclusion (Catanzaro, Cassino, Reggio Calabria, Teramo, Molise). On the other hand, the
University of Verona tops the ranking thanks to the Alias Career index. In fact, it has a Non-disclosure
Agreement and publicises the Alias Career on the university website (Alias Career Inclusivity Index:
100/100). Moreover, thanks to the work of the Research Centre PoliTeSse of Politics and Theories of
Sexuality, seminars, conferences and workshops on LGBT+ issues are regularly held, often with the
collaboration of LGBT+ associations, and a counselling service for LGBT+ people is present. Currently
no all-gender bathrooms are available and no staff training courses on LGBT+ inclusion are held
(Context Index: 55.56/100).
    The University of Basilicata was the first university in Italy to adopt a Non-disclosure Agreement
on 18 May 2019, and like the University of Verona, it has a score of 100/100 in the Alias Career Index.
Table 1
LGBT+ University Inclusion Index – Ranking 2018/2019
    It achieves the same overall score as the University of Verona in the Context Index, a higher score
in involvement and a lower one for education.
    In the third place we find the University Federico II Naples, characterised by a high score in
Education and Employee Training thanks to the only PhD in Italy specialising in Gender Studies, an
important list of seminars and projects on LGBT+ issues held in the academic year 2018/2019, and an
obligatory training course for all technical and administrative staff on the promotion of the culture of
diversity. University Federico II Naples is, however, lacking in the provision of services such as all-
gender bathrooms and in the establishment of a reporting procedure for crimes against the LGBT+
community, as well as in the introduction of the Non-disclosure Agreement.
    Universities with a score equal to “0” in Employee Alias Career are those that provide access to the
Alias Career only for students. This is shown in the fourth position in the ranking in the case of the
University of Turin. The analysis allowed us to identify a wide range of good or best practices in the
inclusion of LGBT+ leading to a better position in the ranking as shown in Table 1. They regard specific
curricula on gender studies (such as the Gemma Master, a pilot project in the field of Women´s Studies
and Gender Studies with the participation of a number of universities supported by the European
Commission) or dedicated courses (such as the course on history of homosexuality taught at the
Department of Art, Music and the Performing Arts at the University of Turin). Best practices also
involve the teaching of courses to promote diversity devoted to managerial and technical-administrative
staff (such as the mandatory online training course held in 2018 in the University of Naples and in the
University of Calabria on how to counter sexism and homophobia) and conferences and seminars on
the subject. Other actions include counselling services, online platforms or networking to promote the
culture of diversity.

4. Conclusions and policy implications
    In this paper we investigated the capacity of universities to favour LGBT+ inclusion in academic
life. To this end we developed the first LGBT+ University Inclusion Index by using fuzzy rule-based
systems of the Mamdani-Assilian type [3] [4] and used it to rank Italian Universities. The indicators
were designed with the collaboration of six LGBT+ student unions, four experts, and the National
Conference of Equal Opportunities Bodies of Italian Universities.
    Fuzzy rule-based systems provided an excellent tool to monitor different dimensions of the LGBT+
inclusion: the Context and the Alias Career. These two dimensions were in turn split into sub-indices
to provide an overview of the degree of inclusiveness in the various dimensions (Education and
Employee Training, Involvement and Collaboration and Services for Context Index; Students’ Alias
Career-Access Criteria and Employees Alias Career for Alias Career Index).
    In our analysis, related to the academic year 2018/2019, we found that the two Universities
characterised by the maximum level of Alias Career inclusiveness, thanks to the adoption of the Non-
disclosure Agreement are also the best: University of Verona and University of Basilicata.
    In terms of policy implications, one of the main results of this study concerns the relevance of an
operational anti-discriminatory plan involving all the identified dimensions rather than a single action:
the introduction of the Alias Career, even if in its most inclusive version, is not sufficient in itself to
guarantee inclusion for all sexual minorities. Evidence of this is to be found in the ranking of the
Universities of Camerino (13) and Venice (18), despite their high scores in the Alias Career index.
    The results recommend an inclusion strategy aimed at improving all the sub-dimensions identified
in this study: education, research and curricula gender-oriented, training courses on LGBT+ issues for
faculty members and for technical and administrative staff, collaboration with LGBT+ students unions
or allies, involvement of sexual minority associations in the organisation of anti-discriminatory
activities and events, the provision of different services to protect and support sexual minorities,
including the introduction of the Non-disclosure Agreement and provision for the Alias Career.
Moreover, in the definition of an intervention strategy aimed at LGBT+ inclusion, the collaboration of
LGBT+ associations is crucial as well as the capacity to devise new services and innovative policies,
maintaining a fluid and open-minded approach (the same approach that led to the new version of the
Alias Career).
   Finally, we strongly recommend the introduction of the LGBT+ University inclusion index in the
evaluation of universities, such as the Biennial Report on the State of the University System and
Research, produced by ANVUR (National Agency for the Evaluation of University and Research) and
the Italian Universities Ranking of CENSIS. The incorporation into these rankings of the degree of
inclusiveness of Universities will allow potential students to make informed choices. As a possible
extension of this study, we plan to re-evaluate the degree of LGBT+ inclusion in the academic year
2019-2020, also taking account of the effects of the pandemic.
