        <p>Public participation in scientific research activities is also known as citizen science. It includes a set of methodological approaches for engagement and recruitment of non-expert volunteers coordinated by expert scientists, definition of tasks and scope aimed at organization of a community to achieve research purposes. One of the main goals of citizen science is to find scientific-based solutions to societal needs. Citizen science community acts as a system composed by social and technical components. Public participation is, in fact, supported using information technologies and digital technologies, such as smartphone and personal mobile devices. Participants and experts also organize and coordinate their activities through social media platforms. However, integration of citizen science approaches in a socio-technical perspective is a research topic not yet explored. Scope of this short position paper is to pose some reflection on possible integration starting from a brief review of main characteristics of citizen science.</p>

      <title>1. Introduction and motivation</title>
      <p>
        Citizen science is a set of methodological approaches aimed at increasing public participation in
scientific research activities [
        <xref ref-type="bibr" rid="ref1 ref2 ref3">1,2,3</xref>
        ]. Application of citizen science is transdisciplinary, allowing
multiple disciplines to join efforts with experts and volunteers to solve societal challenges [
        <xref ref-type="bibr" rid="ref4 ref5 ref6">4,5,6</xref>
        ].
Unlike other types of participative approaches, based on crowdsourcing models, citizen science
enlarges public participation to all steps of a research project, from data collection to interpretation of
results and dissemination of outcomes [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. In this perspective, expert researchers engage amateur
volunteers in the definition of common and shared research design at the scope to find scientific-based
solutions to societal needs and environmental challenges [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. In a citizen science approaches, external
environment indicates contextual background in which an organized groups of researchers and
volunteers act. Contextual background is understood as the set of environmental, geographic,
sociodemographics, cultural and jurisdictional factors. Societal challenges can be linked to different issues
that threaten contemporary societies: climate change, water resources management, sustainable
development, urban mobility, and urban planning, just to report most common application examples.
Citizen science can represent a method to support and coordinate public call-to-action aimed at
comanagement and co-assessment of public resources – such as water, land, cultural heritage – combining
scientific purposes and societal challenges to address decision and policy making processes through
bottom-up approaches [
        <xref ref-type="bibr" rid="ref2 ref3">2,3</xref>
        ].
      </p>
      <p>
        Literature usually distinguishes ideal types of citizen science: (1) contributory, (2) collaborated, and
(3) co-created [
        <xref ref-type="bibr" rid="ref1 ref3 ref4">1,3,4</xref>
        ]. Contributory ideal type refers to projects designed by expert scientists. The role
of volunteers is limited to data collection [
        <xref ref-type="bibr" rid="ref1 ref3 ref4">1,3,4</xref>
        ]. In a collaborated ideal type, expert scientists generally
define research goals, while volunteers can contribute to refine research design and activities such as
data collection and analysis, and dissemination of outcomes [
        <xref ref-type="bibr" rid="ref1 ref3 ref4">1,3,4</xref>
        ]. In a co-created ideal type, expert
scientists and volunteers collaborate, co-designing and co-conceptualizing all stage of the scientific
process [
        <xref ref-type="bibr" rid="ref1 ref3 ref4">1,3,4</xref>
        ].
      </p>
      <p>
        Citizen science constitutes an innovative research approach aimed at the integration of human and
societal perspectives into scientific tasks [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] by (1) investigating into bidirectional relationships
between environmental and socio-economic and cultural systems; (2) modelling new organizational
processes supported by flexible interaction between humans and computers [
        <xref ref-type="bibr" rid="ref7 ref8">7,8</xref>
        ].
      </p>
      <p>Starting from these conceptual assumptions, this short position paper intends to pose a reflection on
possible integration and interpretation of citizen science in a socio-technical theoretical perspective.</p>

      <title>Social components</title>
      <p>The participation of volunteers in a citizen science project is a collective process aimed at identifying
scientific-based solutions to collective issues. It implies the construction of structurally organized
groups of volunteers, the adoption of co-design research methodologies among all the participants and
the definition of common and collegial goals.</p>
      <p>
        A citizen science community is a complex organization generally composed by groups of expert
scientists and volunteers, as depicted in table 1. Expert scientists are people who have academic or
scientific background [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. They usually coordinate and supervise research activities as research design,
goals definitions, data collection settings and protocols [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. Volunteers constitutes a heterogeneous
group with no academic qualification and profound differences in terms of professional expertise,
education, personal interests, and socio-cultural background [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Volunteers, therefore, interact and
collaborate within a context of social norms, legal frameworks, cultural values, and environmental
factors that influence the definition of common research goals, the implementation of methodologies
suitable for achieving the purposes and for adoption of suitable tools [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. Volunteers can be categorized
as (1) decision makers, (2) stakeholders, (3) citizens and general public. Decision makers and
stakeholders constitute subgroups of expert amateurs, professionals and local authorities that give their
contribution in participative science by expertise and advanced education. Citizens and general public
are generally recruited and engaged within organized groups such as civic groups, neighborhood
organizations, target communities. In this perspective, volunteers’ engagement acquires a meaning
around the sense of community and belonging. Local communities’ participation in citizen science
activities enhances the role of citizens into research and decisional processes [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ] and individual
motivations to participation. These latter usually refer to: (1) personal interest [
        <xref ref-type="bibr" rid="ref1 ref11">1,11</xref>
        ]; (2) scientific
knowledge for the better understanding of their environment or to gain political leverage [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]; (3)
improving relationships between people, institutional actors and stakeholders [
        <xref ref-type="bibr" rid="ref2 ref7">2,7</xref>
        ] aimed at social
learning and co-management of common resources and goods [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ]; (4) promoting joint action and civic
participation on environmental topics with socio-economic and cultural implication or that involves
socio-organizational aspects [
        <xref ref-type="bibr" rid="ref3 ref8">3,8</xref>
        ].
      </p>
      <p>
        Expertise, education, socio-cultural background, and motivations are key aspects for the definition
of roles within a citizen science community and defining the level of participation in scientific tasks.
The participatory process, in fact, is articulated in different steps: envisioning and goal settings, model
formulation, data collection and cross-checking, model application and evaluation of outcomes [

      <p>
        The implementation of web-based technologies into citizen science approaches gives new
perspectives for engagement enlarging participation from physical to virtual spaces. In particular, social
media systems allow rapid sharing of information at low cost connecting and mobilizing people within
online communities. Involving online communities into the citizen science approach implies a new form
of participatory organization around (1) remote work teams, (2) collaborative task management, (3)
management of the dynamic division of labor, and (4) communication with large audience [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ].
Introduction of web-based technologies and social media tools in citizen science investigation is
reshaping socio-spatial networks of participation, projecting the engagement of volunteers from
community-based approaches towards virtual contexts [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ]. The adoption of computer-based models –
e.g., software platforms, suitable smartphone applications – is functional to:
(1) Support recruitment and engagement activities [
        <xref ref-type="bibr" rid="ref15 ref16">15,16</xref>
        ] enlarging participation by means
of non-intrusive tools, commonly used in daily life of citizens [
        <xref ref-type="bibr" rid="ref17 ref18">17,18</xref>
        ].
(2) Support data collection activities and crowdsourcing by means of distributed network of
human sensors [
        <xref ref-type="bibr" rid="ref19">19</xref>
        ] that operate at different scale of geographic scale and time.
(3) Support communication efforts directed to general public or specific target groups.
(4) Analyze social networks patterns to identify potential stakeholders to involve, defining
roles and tasks within the organization [
        <xref ref-type="bibr" rid="ref14 ref20 ref21">14,20,21</xref>
        ].
(5) Investigate internal interactions between members of an online community [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ] and
external interactions between users and their context of interaction [
        <xref ref-type="bibr" rid="ref23 ref24">23,24</xref>
        ].
(6) Evaluate individual and collective efforts by visualization of results.
      </p>
      <p>
        (7) Enhance a constant information flow for directional purposes [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ].
      </p>
      <p>These points synthetize the technological framework of citizen science platforms as recruitment
pools between projects and volunteers. Platforms such as Zooniverse and Spotteron, for example, offer
features and tools for supporting the participation of volunteers in scientific research and knowledge
co-production processes through data collection functions from geo-localized observations, social
community extensions – such as newsfeeds, forum, comments, liking and user following, data
visualization and summary and data visualization dashboard and rating of observations for the data
validation and information provided by users. These functionalities are aimed at building operative
communities of volunteers that share opinions and experiences in relation to topics of scientific interest,
highlighting their impacts on daily experiences.</p>

      <title>3. Benefits and limits of citizen science</title>
    </sec>
    <sec id="sec-6">
      <title>3.1. Benefits</title>
      <p>
        The benefits of citizen science are measured in terms of raising knowledge through co-production
and constant dialogue between citizens and experts around environmental and societal challenges.
Benefits and opportunities are bidirectional for experts and volunteers. Experts can broaden availability
of data at low cost. Volunteers can benefit within the organization in terms of professionalization,
acquisition of skills and awareness, through the possibility of continuous training, dialogue and open
discussion with experts and stakeholders [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. Citizen science represents a common space for socializing;
it creates a sense of belonging that contributes to participants’ performance and outcomes [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ] by
improving efficiency, effectiveness and the scope of research processes [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. Citizen science creates a
space for social inclusivity, dialogue between stakeholders and allows people to express themselves by
giving a voice to non-experts [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. Social inclusivity—derived from citizen science activities—
contributes to mitigate conflicts around environmental and resources management [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ]. It also
contributes to improve the economic situation of participants by giving them knowledge and tools for
managing local issues [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ].
      </p>
      <p>
        Citizen science, firstly, encourages dialogue and the exchange of information between citizens and
experts, in order to increase awareness on public interest issues and in decision-making processes
[
        <xref ref-type="bibr" rid="ref26 ref27">26,27</xref>
        ]. Dialogue and information exchange are also functional to collaborative modelling of tools and
processes [
        <xref ref-type="bibr" rid="ref28 ref7">7,28</xref>
        ], definition of methodologies, protocols and research methods that reflect shared points
of view between experts and engaged volunteers [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ].

    <sec id="sec-7">
      <title>Limits</title>
      <sec id="sec-7-1">
        <title>The limits related to citizen science can be divided into:</title>
        <p>1. Socio-cognitive
2. Technological</p>
        <p>
          As previously reported, citizen science aims to integrate humanistic and socio-cultural aspects into
the processes and definition of research protocols to arrive at a co-production of knowledge. Human
perceptions and socio-cultural background may affect data collection activities and the fulfillment of
tasks assigned to the volunteers [
          <xref ref-type="bibr" rid="ref30 ref7">7,30</xref>
          ]. Levels of education or training and cognitive biases can threaten
the validity and reliability of volunteers’ observations [
          <xref ref-type="bibr" rid="ref10 ref31">10,31</xref>
          ]. Subjective perceptions and biases not
only influence interpretation and dissemination of results, but also may have potential negative
consequences in economic, human and environmental concerns [
          <xref ref-type="bibr" rid="ref31">31</xref>
          ].
        </p>
        <p>
          Still on the social implications, citizen science approaches can be influenced by social marginality
deriving from controversies, insufficient funding, and barriers to participation related to social
marginalization or political and jurisdictional barriers [
          <xref ref-type="bibr" rid="ref2 ref8">2,8,32,33</xref>
          ]. Marginalization usually takes origin
from social, political and jurisdictional issues that limit the participation to specific groups and exclude
others [
          <xref ref-type="bibr" rid="ref10 ref2">2,10,34</xref>
          ].
        </p>
        <p>These aspects can be further aggravated by the digital divide. The latter sharpens the differences
between social groups often leading to the marginalization of disadvantaged groups. Participation in
research projects according to citizen science approaches thus risks being elitist. Such differentiations
may be reflected geographically, where network coverage is greater in urban than in rural areas.</p>
        <p>
          From a technical point of view, these issues lead to discontinuity in data collection, exchange and
processing of information useful for implementing analytical models and for achieving valid results.
Citizen science needs the provision of adequate infrastructures to support communication, (online)
training, storage of data collected, to offer analysis and standardize program evaluation [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ]. Appropriate
technology helps citizen science projects. Internet and smartphones are fundamental tools to facilitate
the participation, but they are not a warranty of data quality and training is needed for the correct use
of these technologies in citizen science tasks [34]. The success of participatory approaches, as
crowdsourcing and citizen science, does not rely only on technological advances, but also on the
capacity to engage people and foster cooperation and coordination between participants and
stakeholders around common community concerns [
          <xref ref-type="bibr" rid="ref17 ref18">17,18</xref>
          ].

    <sec id="sec-8">
      <title>4. A socio-technical perspective for Citizen science</title>
      <p>The integration of citizen science into a socio-technical system represents a yet unexplored research
topic. Given the previous context, possible research scenarios include analysis of the interactions
between people, technologies and the external environment [35]. In particular, research on the topic of
citizen science from a socio-technical perspective can be useful to deepen the motivations and human
behaviors of the participants within a community of researchers and volunteers, the methods of internal
organization and alignment of aims and processes, and finally the contribution of digital technologies
to support research activities [36]. The integration of citizen science into socio-technical perspectives
constitutes a long and challenging research path in absence of solid reference studies. Here, it is only
possible to trace some research input, which must be followed not only by theoretical reflections but
above all empirical case studies. Studies on open-source communities and software projects can offer
initial insights on the collaboration between volunteers and personal motivations within small
organizations with targeted and specific goals [37,38], according to inductive analysis methods in
search of general and replicable categorizations from single case studies [37,38].</p>
      <p>A socio-technical perspective, in short, can be functional to understand the changes at the
organizational level in the modalities of participatory science and the changes both in behavioral and
cultural terms (social learning, professionalization of volunteers, greater awareness of social and
environmental issues) and in technological terms (use of digital tools in scientific research, new models
for collecting and analyzing data from voluntary observations, development of management platforms,
digital technologies to direct operational activities).</p>
      <p>Socio-technical perspectives can also help to study and understand citizen science communities as
work system that relies on human, informational and technical infrastructure [36]. Participants (experts
and non-experts) collect data, process and exchange information for knowledge co-production, finding
new forms of interaction and cooperation with the support of digital platforms as recruitment and
communication tools. As a work system, a citizen science community interacts within a specific
environment given by geographical, ecosystem and socio-cultural conditions that affect behaviors and
choices with the support of information and digital technologies.</p>
      <p>
        Categories proposed by Alter (2020) such as unity of purpose and compatibility between the
participants, alignment of roles and tasks to be performed, sharing of responsibilities, exchange and
continuous access of information and interoperability with technologies [36] can represent the pillars
for the proper systemic functioning of an organized citizen science community. In this regard, definition
of a research design suitable to solve societal and environmental challenges, identification of target
groups active in a specific context, social pattern analysis and definition of shared standard protocols
of research among experts and volunteers could represent a roadmap towards unity of purpose,
alignment of processes and tools modeling at the base of the socio-technical functioning of a citizen
science organization [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ].
      </p>
      <p>A community active in citizen science can also be interpreted as a univocal and congruent system
of values, in which research objectives are aligned with personal and collective needs [35,39]. The
purpose of citizen science can be addressed towards the joint optimization of its social and technical
components to ensure the efficiency and validity of research work in connection with social goals and
collective satisfaction [35]. On the one hand, the research goals must correspond with collective needs
to find scientific solutions to collective problems. On the other hand, the participation of volunteer
citizens must be favored by easy access to information and by the assignment of tasks that are easy and
intuitive to carry out using non-intrusive and everyday technologies such as smartphones and personal
mobile devices [35].</p>
      <p>To measure the functioning of a socio-technical system within a citizen science community, it would
be useful to carry out environmental and socio-cultural context analysis to identify strengths and
weaknesses, causes of potential conflict, legal and cultural obstacles to participation [39]. Context
analysis is also useful to identify behavioral and socio-cultural patterns to evaluate the conditions of
collaboration and cooperation between volunteers and between them and team of coordinating experts
[39]. Finally, at the technological level, the context analysis would help to understand any changes and
benefits; understand if technologies help in problem-solving problems or create issues; whether they
help overcome cognitive biases that threaten the validity and reliability of citizen science approach to
scientific research [39].</p>
