Older Adults and Emerging Digital Service Delivery: A Mixed Methods Study on Information and Communications Technology Use,Skills, and Attitudes

Based on data from a survey (n = 3291) and 14 qualitative interviews among Danish older adults, this study investigated the use of, and attitudes toward, information communications technology (ICT) and the digital delivery of public services. While age, gender, and socioeconomic status were associated with use of ICT, these determinants lost their explanatory power when we controlled for attitudes and experiences. We identified three segments that differed in their use of ICT and attitudes toward digital service delivery. As nonuse of ICT often results from the lack of willingness to use it rather than from material or cognitive deficiencies, policy measures for bridging the digital divide should focus on skills and confidence rather than on access or ability.     

The mobile Internet and digital citizenship in African-American and Latino communities

Smartphone use is transforming the meaning of being online, especially for African-Americans and Latinos. To what extent has this enabled these populations to become digital citizens, able to participate in society online? Internet use is increasingly important for the exercise of the political, economic and social rights that have often been associated with citizenship [Mossberger, K., Tolbert, C. J., &; McNeal, R. S. (2008). Digital citizenship: The Internet, society, and participation. Cambridge, MA: MIT Press], and can be measured by the political and economic activities that individuals engage in online. Using unique survey data from a diverse city, we use multilevel analysis and interactions to examine relationships between forms of access and activities online in 2013, controlling for neighborhood context as well as individual characteristics. In contrast with prior work, we find that while broadband access is most strongly associated with political and economic activities online, that mobile is as well. The effects are strongest for African-Americans and Latinos, especially for Latinos who live in heavily Latino neighborhoods – who have lagged behind furthest in Internet use.     

Connected seniors: how older adults in East York exchange social support online and offline

ABSTRACT

How do older adults mobilize social support, with and without digital media? To investigate this, we focus on older adults 65+ residing in the Toronto locality of East York, using 42 interviews lasting about 90 minutes done in 2013–2014. We find that digital media help in mobilizing social support as well as maintaining and strengthening existing relationships with geographically near and distant contacts. This is especially important for those individuals (and their network members) who have limited mobility. Once older adults start using digital media, they become routinely incorporated into their lives, used in conjunction with the telephone to maintain existing relationships but not to develop new ones. Contradicting fears that digital media are inadequate for meaningful relational contact, we found that these older adults considered social support exchanged via digital media to be real support that cannot be dismissed as token. Older adults especially used and valued digital media for companionship. They also used them for coordination, maintaining ties, and casual conversations. Email was used more with friends than relatives; some Skype was used with close family ties. Our research suggests that policy efforts need to emphasize the strengthening of existing networks rather than the establishment of interventions that are outside of older adults’ existing ties. Our findings also show that learning how to master technology is in itself a form of social support that provides opportunities to strengthen the networks of older adults.     

Why practitioners do (not) apply crisis communication theory in practice

Twenty-five in-depth interviews with Belgian crisis communication practitioners were conducted to examine the gap between theory and practice. Crisis communication has become an important research area within public relations. Several studies have resulted in theories and guidelines regarding the effective use of communication during organizational crises. Unfortunately, these findings are not always put into practice. This study examines to what extent public relations practitioners apply theory in practice during crises and why. The findings offer an opportunity to formulate potential ways in which we can bridge the scholar-practitioner divide in public relations, through guidelines for both scholars and practitioners.     

From ‘What the F#@% is a Facebook?’ to ‘Who Doesn’t Use Facebook?’: The role of criminal lifestyles in the adoption and use of the Internet

Concerns about a digital divide persist and recent calls have been made for understanding how lifestyles influence Internet adoption and use. Online criminal behaviors have drawn attention from law enforcement, but diffusion of innovation theory suggests higher propensities for crime, particularly street crime, reduces the likelihood of Internet use. Drawing from this theory and research on the role of street criminal lifestyles on technology adoption, this study examined patterns of Internet use among a sample of 585 individuals at-risk for and involved in street crime. Results from our logistic and negative binomial regression analyses lead to two general conclusions: (1) compared to research on the general population, similar predictors and lower rates of Internet participation and usage are observed, and (2) mixed evidence suggests participation in criminal lifestyles contributes to digital inequality. The results support a theory of technological diffusion to marginalized populations. We conclude by discussing the expansion of technology, digital inequality, and crime.

The value of mixed-method longitudinal panel studies in ict research

This paper uses a unique British three-wave longitudinal dataset to examine the rates of transitions into and out of 'ICT poverty' defined as having Internet access in the household and/or having a mobile phone. This serves three purposes: it shows that many are still 'passing by' ICT ownership, that 'gaining ICT' access is not a one-way street - many just pass through; and that the rates of dropping out differ for different ICTs and for different groups of people. This has implications for both commercial and public policy strategy. It also shows the value of longitudinal approaches to data collection without which this kind of analysis would be impossible.
