Relational uncertainty management in adult children of divorce     

Sylvia L. Mikucki-Enyart  Sarah R. Petitte  Sarah E. Wilder 《Journal of Applied Communication Research》2018,46(4):469-490

Utilizing uncertainty management theory (UMT) and a multiple goals theory of personal relationships (MGPR) the present study examined how adult children of divorce (ACOD) manage relational uncertainty following parental divorce. In-depth, semi-structured interviews with 25 adult children who had experienced parental divorce when they were 18 years of age or older revealed two, broad types of information acquisition strategies: deliberate (i.e. information-seeking and information-avoiding) and incidental (i.e. incidental information acquisition). Deliberate information acquisition strategies were animated by several goals, including reducing and maintaining uncertainty, avoiding feeling caught, and protection. Alongside goals, various constraints (e.g. target efficacy, coping efficacy) played a role in ACOD’s relational uncertainty management. We discuss these results in relation to their theoretical and practical applications.  相似文献   

Does Facebook Use Predict College Students’ Social Capital? A Replication of Ellison,Steinfield, and Lampe’s (2007) Study Using the Original and More Recent Measures of Facebook Use and Social Capital     

Mariek M. P. Vanden Abeele  Marjolijn L. Antheunis  Monique M. H. Pollmann  Alexander P. Schouten  Christine C. Liebrecht  Per J. van der Wijst 《Communication Studies》2018,69(3):272-282

In 2007 Ellison, Steinfield, and Lampe published an article on the positive association between Facebook use and social capital that started a decade of research on the social outcomes of social network site use. Although cited almost 9,000 times, it received critique on the conceptualization and operationalization of Facebook use and social capital. In this study we replicate Ellison et al.’s study with original and alternative measures of social capital and Facebook use, thereby shedding light on the robustness, stability, and ecological validity of the original findings. We found that Facebook intensity positively predicts the original social capital measures, lending support to the validity of the original findings. Its relationship with structural measures, however, was weak for bridging and absent for bonding social capital.  相似文献   

Normalization of zero-inflated data: An empirical analysis of a new indicator family and its use with altmetrics data     

Lutz Bornmann  Robin Haunschild 《Journal of Informetrics》2018,12(3):998-1011

Recently, two new indicators (Equalized Mean-based Normalized Proportion Cited, EMNPC; Mean-based Normalized Proportion Cited, MNPC) were proposed which are intended for sparse scientometrics data, e.g., alternative metrics (altmetrics). The indicators compare the proportion of mentioned papers (e.g. on Facebook) of a unit (e.g., a researcher or institution) with the proportion of mentioned papers in the corresponding fields and publication years (the expected values). In this study, we propose a third indicator (Mantel-Haenszel quotient, MHq) belonging to the same indicator family. The MHq is based on the MH analysis – an established method in statistics for the comparison of proportions. We test (using citations and assessments by peers, i.e. F1000Prime recommendations) if the three indicators can distinguish between different quality levels as defined on the basis of the assessments by peers. Thus, we test their convergent validity. We find that the indicator MHq is able to distinguish between the quality levels in most cases while MNPC and EMNPC are not. Since the MHq is shown in this study to be a valid indicator, we apply it to six types of zero-inflated altmetrics data and test whether different altmetrics sources are related to quality. The results for the various altmetrics demonstrate that the relationship between altmetrics (Wikipedia, Facebook, blogs, and news data) and assessments by peers is not as strong as the relationship between citations and assessments by peers. Actually, the relationship between citations and peer assessments is about two to three times stronger than the association between altmetrics and assessments by peers.  相似文献
