Understanding the Adoption Process of National Security Technology: An Integration of Diffusion of Innovations and Volitional Behavior Theories

After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals’ health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety.     

A simple greedy approximation algorithm for the minimum connected $$$$-Center problem

In this paper, we consider the connected \(k\)-Center (\(CkC\)) problem, which can be seen as the classic \(k\)-Center problem with the constraint of internal connectedness, i.e., two nodes in a cluster are required to be connected by an internal path in the same cluster. \(CkC\) was first introduced by Ge et al. (ACM Trans Knowl Discov Data 2:7, 2008), in which they showed the \(NP\)-completeness for this problem and claimed a polynomial time approximation algorithm for it. However, the running time of their algorithm might not be polynomial, as one key step of their algorithm involves the computation of an \(NP\)-hard problem. We first present a simple polynomial time greedy-based \(2\)-approximation algorithm for the relaxation of \(CkC\)—the \(CkC^*\). Further, we give a \(6\)-approximation algorithm for \(CkC\).     

Campus politics,student societies and social media

The university campus has often been seen as an important site for the politicization of young people. Recent explanations for this have focused attention upon the role of the student union as a means to enable a ‘critical mass’ of previously isolated individuals to produce social networks of common interest. What is missing from these accounts, however, and what this article seeks to address, is how these factors actually facilitate the development of political norms and the active engagement of many students. Drawing upon qualitative data from three countries we argue that it is the milieu of the smaller student societies that are crucial for facilitating the habitus of the student citizen. They provide the space for creative development and performance of the political self, affiliations to particular fields and access to cultural and social capital. Moreover, we contend that these processes of politicization are increasingly enacted through social media networks that foreground their importance for developing political habitus in the future.     

Voices of resilience: older adults in hospice care

Terminally ill older adults have the capacity to live well in the context of dying. Having negotiated a lifetime of challenges, they have resources to demonstrate resilience and achieve wholeness in life's final phase, but research has not adequately investigated this process. This qualitative research study considered the paths to resilience used by 30 older adult hospice clients in Kansas and Illinois. Responses were coded using the grounded theory method of Strauss and Corbin (1990) where data drives interpretation and text is coded into categories. Results centered on four themes that included: (1) a redefinition of self; (2) use of religion/spirituality or openness to uncertainty; (3) maintenance of social investments; and (4) guarding independence even as the scope of life contracted. Results imply that attention should be paid to building environments of wellness. This may be accomplished paradoxically through facilitating continuity of client interests and yet opportunities for creativity and growth as well. Listening with a healing stance and cultivating a habit of being fully present in interactions with clients assist in this process.     

Do Young Children's Representations of Discipline and Empathy Moderate the Effects of Punishment on Emotion Regulation?

This study examined whether children's representations of parenting (perceptions of authoritative discipline and empathy) moderated the association between harsh punishment—including corporal punishment (CP) and verbal punishment (VP)—and children's emotion regulation at the age of five years. Participants were 559 low‐income mother‐child dyads. Maternal self‐reports and home observations were used to measure punishment. Children's representations were assessed using the MacArthur Story Stem Battery. Children's emotion regulation was assessed by observer rating via the Leiter International Performance Scale–Revised. Hierarchical multiple regressions revealed that children's authoritative disciplinary representations moderated the effects of both VP and CP on children's emotion regulation. Empathic representations moderated the effects of VP only on children's emotion regulation. The current findings highlight the role of children's internal representations as potential protective factors in the context of harsher forms of punishment.     

Children's Interpretations of Ambiguous Provocation From Their Siblings: Comparisons With Peers and Links to Relationship Quality

This study investigated how six‐ to eight‐year‐old children interpret ambiguous provocation from their siblings. In particular, we examined how children's attributions of their siblings' intent (1) differed from those for their peers, (2) varied as a function of the structural features of the sibling relationship, and (3) were associated with the affective qualities of the sibling relationship. A total of 121 children were presented with ambiguous provocation scenarios in which three groups of agemates were described as the perpetrators of harm (siblings, friends, and disliked peers). Scenarios were designed to assess children's attributions of hostile, instrumental, and accidental intent. Children attributed more hostile intent to disliked peers than to siblings and less hostile intent to friends than to siblings. Accidental and instrumental intent attributions were equally likely for friends and siblings but less common for disliked peers. Children attributed more hostile intent to older siblings, and more instrumental intent to laterborn siblings who were chronologically younger. Children's attributions of siblings' intent were related to both parents' and children's reports of the affective features of siblings' interactions. Results provide new insight into how children's construals of others' actions are grounded in the unique features of their relationships with particular interaction partners.     

Developing Survey Measures of Inequality of Autonomy in the UK

This paper explores the development of survey questions to measure autonomy, interpreted as the degree of choice and control a person has in key areas of his or her life. A review of the theoretical literature leads to a conceptualisation of autonomy as consisting of three components: (1) self-reflection, (2) active or delegated decision-making, and (3) a wide variety of high-quality options. Three major barriers to autonomy are identified: (1) conditioned expectations, (2) coercion, and (3) structural constraints, including lack of advice and support. A suite of questions designed to assess these components and barriers was devised and subjected to cognitive testing with a purposive sample of 34 individuals with diverse characteristics. The tests resulted in refinements to the language, response categories and phrasing of questions. Analysis of responses indicated that issues of decision-making and range and quality of options were easier for respondents to grasp than questions about self-reflection, and conditioned expectations could be detected only indirectly. Nevertheless the components of, and barriers to, autonomy could be separately identified. The article concludes that despite limitations, survey measurement of the complex concept of autonomy is possible and revealing.
