Q

What is meant by the identifying individuals strategy? (Valente, 2012)

A

Indentifying individuals who are selected on the basis of some network property:

  1. Leaders
  2. Bridging individuals (brokers), they can have better positions to change others.
  3. Low-threshold change agents, they are willing to adopt an idea earlier than their peers -> create early momentum for the change and accelerate the time to reach a critical mass.

Q

What is meant by the segmentation strategy? (Valente, 2012)

A

That the intervention is directed toward groups.

  1. Mutually exclusive vs. cliques
  2. Core-periphery network
  3. Identify nodes that occupy the same roles in the organization or community.

Q

What is meant with the induction strategy? (Valente, 2012)

A

The excitation of the network occurs such that novel interactions between people are activated.

  1. Word-of-mouth (interpersonal among any and all social ties)
  2. Snowball-sampling (respondent-driven sampling), hard to reach respondents (closely-associated peers)

Q

What is meant with the alteration strategy? (Valente, 2012)

A

The interventions that change the network.

  1. Adding/deleting nodes
    - outside change agents (expert consultants, support groups)
    - remove nodes that occupy critical positions in a network (terrorist)
  2. Adding/deleting links
    - bridge disconnected or loosely connected groups.
  3. Rewiring existing links
    - increase efficiency or improve performance based on certain goals.
    - connect individuals with different attributes
    - optimal networks are those with short average distance between nodes and a high degree of clustering

Q

What factors play a role in choosing the right network intervention? (Valente, 2012)

A
  1. Network structure
    - advice networks: experts and people with credible sources of information, they have considerable technical knowledge about the idea of product.
    - discussion networks: relationships are high in trust, mutual understanding and interpersonal affect in which communication and persuasion flow easily.
  2. Geographic distance
  3. Characteristics of the behavior (increase in value as more people adopt)
  4. Prevalence
    - high levels of prevalence network interventions can be used to find individuals who have not yet adopted behavior in question.
    - low prevalence network intervention can identify whether early users are leaders and are thus well positioned to accelerate behavior spread.
  5. Perceived political support or acceptability of the behavior.

Q

What are the six steps of the intervention mapping process? (Kok et al., 2016)

A
  1. Conduct a needs assessment or problem analysis by identifying what needs to be changed and for whom.
  2. Crate matrices of change objectives by combining (sub)behaviors with behavioral determinants to identify which beliefs should be targeted by the intervention.
  3. Select theory-based intervention methods that match the determinants into which the identified beliefs aggregate and translate these into practical applications.
  4. Integrate the practical applications into an organized program.
  5. Plan for adoption, implementation and sustainability of the program real-life contexts by identifying program users and supporters and determining what their needs are sand how these should be fulfilled.
  6. Generate an evaluation plan to conduct effect and proces evaluations to measure program effectiveness.

Q

What is meant by determinants? (Kok et al., 2016)

A

Causes/things to udnderstand the behavior.

Lowest level: individual thoughts, emotions etc.

Aggregate level: similar related thoughts, attitudes.

Determinants are defined commonly, they cannot be targeted directly.

Q

What are the results of the literature review of Tengstedt et al. (2018)?

A

There are challenges when it comes to validity in health intervention studies on social media. Especially with surveys and interviews; participants can over-and under-report, misunderstand questions, have subjective perceptions, etc. -> hard to generalize. However, knowledge of the interventions can help researchers to improve further interventions.

Q

What is the difference in functions between social media and social networking? (Moorhead et al., 2013)

A

Social media functions as a communication channel that delivers a message, which involves asking for something.

Social networking is two-way and direct communication that includes sharing of information between several parties.

19
Q

What are the 7 points of the social media framework? (Moorhead et al., 2013)

A
  1. Identity: the extent to which users reveal themselves.
  2. Conversations: the extent to which users communicate with each other.
  3. Sharing: the extent to which users exchange, distribute and receive content.
  4. Presence; the extent to which users know if others are available.
  5. Relationships: the extent to which users know the social standing of others and content.
  6. Reputation: the extent to which users know the social standing of others and content.
  7. Groups: the extent to which users are ordered or form communities.
20
Q

What where the characteristics of the users accessing social media for health communication? (Moorhead et al., 2013)

  3. Lower-income households
21
Q

22
Q

What are the benefits of social media for health communication? (Moorhead et al., 2013)

A
  1. Increase the number of interactions (more available, shared and tailored information as users create and share information)
  2. Access tailored resources
  3. Widen access to those who may not easily access health information otherwise (low cost)
  4. Provide support
  5. Monitor public response to health issues, identify misinformation, monitor disease outbreak
23

24
Q

What is the definition of affordances? (Gaver, 1991)

A

Properties of the world defined with respect to people’s interaction with it. They exist whether the perceived cares about them or not, whether they’re perceived or not.

25
Q

What is meant by perceptible affordance (inter-referential)? (Gaver, 1991)

A

that there is perceptual information available for an existing affordance. What is perceived is acted on.

26
Q

What is meant by hidden affordance? (Gaver, 1991)

A

That there is no information available for an existing affordance

27
Q

What is meant by false affordance? (Gaver, 1991)

A

That there is information that suggests a nonexistent affordance

28
Q

What is meant by sequential affordance? (Gaver, 1991)

A

Situations in which acting on a perceptible affordance leads to information indicating new affordances

29
Q

What is meant by nested affordance? (Gaver, 1991)

A

Affordances that are grouped in space (door and a handle)

30
Q

What is meant by correct rejection? (Gaver, 1991)

A

No affordance nor any perceptual information suggesting it.

31
Q

What are some aspects of affordances that are mentioned in the article of gaver (1991)?

A
  1. The perception of affordances will be determined by culture, social setting, experience and intentions.
  2. You can also hear affordances.
  3. Affordances can be passively perceived, but sometimes you need to explore to understand the affordance.
32
Q

What was the article of Evans et al. (2017) about?

A

Relational approach to understand how people interact with technology. The materiality of technology influences the possibilities for users and an affordance should stay constant, even if the goals change.

33
Q

What are the three criteria to assess an affordance?

A
  1. Confirm proposed affordance is neither the object nor a feature of the object: the relationship between person and object means that affordances neither belong to the environment nor the individual, but rather to the relationship between individuals and their perceptions of environments.
  2. Confirm the proposed affordance is not an outcome: affordances invite behaviors and other outcomes, but are not the outcome itself.
  3. Confirm if the proposed affordance has variability: an affordance has range (less-more)
34
Q

What were the concepts that meet and failed to meet the criteria of the threshold (of criteria to assess an affordance)

A

Meet:

  1. Anonymity (can be feature or object, not an outcome, varies)
  2. Persistence (e-mail, can be an object, leads to different outcomes, varies)
  3. Visibility (social media, feature to search and find info, leads to outcomes, varies)

Fail to meet:

  1. Privacy (not a feature, but an outcome, varies)
  2. Collaboration (not an object/feature, can be viewed as an outcome, varies)
35
Q

What is meant by Goffman’s dramaturgy? (Hogan, 2010)

A

Dramaturgical approach for understanding online presentation of self.

  1. Activity takes place in specific bounded settings; norms and goals of specific settings.
  2. Front stage (idealized) vs backstage (real)
  3. Players seek to perform their role as convincingly as possible, much work needed behind the scenes.
36
Q

What is impression management? (Hogan, 2010)

A

The continued presence allows individuals to tweak their behavior and selectively give and give off details. selective disclosure of personal details designed to present an idealized self.

37
Q

What is the exhibitional approach? (Hogan, 2010)

A

An exhibition site can be defined as a site where people submit reproducible data (artifacts). These artifacts are hold in databases. Algorithms selectively bring artifacts out of storage for a particular audiences.

38
Q

What is said about Goffman’s theory applied to online media?

A

“Social media is backstage”; however, because it is private does not mean it is backstage.

39
Q

What are curators?

A

Unique historical artifacts are curated by experts. Select which artworks to display, where to place them and what narrative to tell about this selection. Presence -> data.

40
Q

What is the function of filtering? (Hogan, 2010)

A

It limits which artifacts are on display.

41
Q

What is the function of ordering? (Hogan, 2010)

A

For example, Facebook will select potential friend for the users from a larger set of friends.

42
Q

What is the function of searching? (Hogan, 2010)

A

Filtering (and ordering) based on user input. Filtering and ordering is done on content that includes specific requests from users, sometimes you have to search for something new.

43
Q

What is the meaning of impression management? (Hall et al., 2014)

A

One actively engages in creating, maintaining and modifying an image that reflects one’s ideal self. Online impressions are ‘managed’ by people known offline.
