Abstract This study attempts to identify the potential determinants of advertising avoidance in the context of personalized advertising media, including unsolicited commercial e-mail, postal direct mail, telemarketing, and text messaging. Using a self-administered survey (n = 442), the proposed model is tested with structural equation modeling analysis. The findings indicate that while ad skepticism partially mediates the relationship between ad avoidance and its three determinants (perceived personalization, privacy concerns, and ad irritation), both privacy concerns and ad irritation have a direct positive effect on ad avoidance. However, increased perceived personalization leads directly to decreased ad avoidance.

Biological age measurements (BAs) assess aging-related physiological change and predict health risks among individuals of the same chronological age (CA). Multiple BAs have been proposed and are well studied individually but not jointly. We included 845 individuals and 3973 repeated measurements from a Swedish population-based cohort and examined longitudinal trajectories, correlations, and mortality associations of nine BAs across 20 years follow-up. We found the longitudinal growth of functional BAs accelerated around age 70; average levels of BA curves differed by sex across the age span (50-90 years). All BAs were correlated to varying degrees; correlations were mostly explained by CA. Individually, all BAs except for telomere length were associated with mortality risk independently of CA. The largest effects were seen for methylation age estimators (GrimAge) and the frailty index (FI). In joint models, two methylation age estimators (Horvath and GrimAge) and FI remained predictive, suggesting they are complementary in predicting mortality.

BACKGROUND: Few studies have examined associations of multi-faceted demographic, health and lifestyle factors with long-term change in grip strength performance across the adult lifespan. The aim of this study was to examine the associations of risk factors in specific parts of the adult lifespan (e.g. in early midlife, in late midlife and in old adulthood) separately for women and men. METHODS: Data came from the longitudinal Swedish Adoption/Twin Study of Aging (SATSA). Grip strength performance was followed in 849 participants who were 50-88 years of age at baseline. The follow-up period with seven waves of data of grip strength was 22 years, and the risk factors were measured up to 20 years before the assessment of grip strength. Latent growth modelling was used for the longitudinal analyses. RESULTS: A gender difference in the type of factors associated with grip strength performance and development across the adult lifespan was found. Significant factors for the age slopes for women were stress, smoking and dementia. For men, marital status, mean arterial pressure, physical activity at work and having a chronic disorder were of importance. These factors varied in their associations with grip strength across the adult lifespan. CONCLUSION: Factors measured earlier in adulthood were associated with grip strength decline in late midlife and old adulthood. Gender-specific patterns of risk factors suggest that it may be worthwhile to conduct research on grip and muscle strength (and biological vitality) separately for men and women.

Bivariate dual change score models were applied to longitudinal data from the Swedish Adoption/Twin Study of Aging to compare the dynamic predictions of 2-component theories of intelligence and the processing speed theory of cognitive aging. Data from up to 5 measurement occasions covering a 16-year period were available from 806 participants ranging in age from 50 to 88 years at the first measurement wave. Factors were generated to tap 4 general cognitive domains: verbal ability, spatial ability, memory, and processing speed. Model fitting indicated no dynamic relationship between verbal and spatial factors, providing no support for the hypothesis that age changes in fluid abilities drive age changes in crystallized abilities. The results suggest that, as predicted by the processing speed theory of cognitive aging, processing speed is a leading indicator of age changes in memory and spatial ability, but not verbal ability.

A number of studies have shown that little replication and extension research is published in the business disciplines. This has deleterious consequences for the development of a cumulative body of knowledge in these same areas. It has been speculated, but never formally tested, that replication research is more likely to be published in lower tiers of the journal hierarchy. The present paper indicates very low levels of replication in management and strategic management journals, regardless of their prestige. Moreover, even those replications that are published tend not to be critical—odd in applied social sciences that are largely preparadigmatic and where extensibility, generalizability and utility of scientific constructs tend to be low. The goal of science is empirical generalization, or knowledge development. Systematically conducted replications with extensions facilitate this goal. It is clear, however, that many editors, reviewers, and researchers hold attitudes toward replication research that betray a lack of understanding about its role. Long-run strategies to dispel these misconceptions must involve changes in graduate training aimed at making the conduct of such vital work second nature. It is further suggested that journals in all tiers create a section specifically for the publication of replication research, and that top-tier journals take the lead in this regard. © 1998 John Wiley & Sons, Ltd.

In a study designed to investigate the respective roles of religious fundamentalism and right‐wing authoritarianism as predictors of prejudice against racial minorities and homosexuals, participants (47 males, 91 females) responded to a series of questionnaire measures of these constructs. Data were analyzed using multiple regression. Consistent with previous research, authoritarianism was a significant and strong positive predictor of both forms of prejudice. With authoritarianism statistically controlled, however, fundamentalism emerged as a significant negative predictor of racial prejudice but a positive predictor of homosexual prejudice. In a second study, we conducted parallel multiple regressions using the correlations from two previously published studies. The Study 1 results were replicated exactly, except that fundamentalism was a nonsignificant predictor of homosexual prejudice. We interpret the results as evidence that Christian fundamentalism consists of a second major component other than authoritarianism—related to Christian belief content—that is inversely related to some forms of prejudice (including racial prejudice) but not others (e.g., homosexual prejudice).

Conspiracy theories flourish in the wide-open media of the digital age, spurring concerns about the role of misinformation in influencing public opinion and election outcomes. This study examines whether news media literacy predicts the likelihood of endorsing conspiracy theories and also considers the impact of literacy on partisanship. A survey of 397 adults found that greater knowledge about the news media predicted a lower likelihood of conspiracy theory endorsement, even for conspiracy theories that aligned with their political ideology.

Abstract Based on the theoretical identification of three different motivational forces for voluntary turnover—affective, calculative, and alternative—we hypothesize that the relationship between supervisor–subordinate relationship quality (i.e., leader–member exchange) and turnover intentions is best represented as curvilinear as opposed to linear. We test this hypothesis in two organizational samples consisting of 402 employees from a water management district and 183 employees from a distribution services organization. We found support for the hypothesis in both samples. We offer directions for future research. Copyright © 2005 John Wiley & Sons, Ltd.

We examined the association between complexity of the main lifetime occupation and changes in cognitive ability in later life. Data on complexity of work with data, people, and things and on 4 cognitive factors (verbal, spatial, memory, and speed) were available from 462 individuals in the longitudinal Swedish Adoption/Twin Study of Aging. Mean age at the first measurement wave was 64.3 years (SD = 7.2), and 65% of the sample had participated in at least three waves of data collection. Occupational complexity with people and data were both correlated with cognitive performance. Individuals with more complex work demonstrated higher mean performance on the verbal, spatial, and speed factors. Latent growth curve analyses indicated that, after correcting for education, only complexity with people was associated with differences in cognitive performance and rate of cognitive change. Continued engagement as a result of occupational complexity with people helped to facilitate verbal function before retirement, whereas a previous high level of complexity of work with people was associated with faster decline after retirement on the spatial factor.

Using a framework previously applied to other areas of media literacy, this study developed and assessed a measurement scale focused specifically on critical news media literacy. Our scale appears to successfully measure news media literacy as we have conceptualized it based on previous research, demonstrated through assessments of content, construct, and predictive validity. Among our college student sample, a separate media system knowledge index also was a significant predictor of knowledge about topics in the news, which suggests the need for a broader framework. Implications for future work in defining and assessing news media literacy are discussed.

This study investigated why and how individuals avoid health information to support the development of models of uncertainty and information management and offer insights for those dealing with the information and uncertainty inherent to health and illness. Participants from student (n = 507) and community (n = 418) samples reported that they avoided health information to (a) maintain hope or deniability, (b) resist overexposure, (c) accept limits of action, (d) manage flawed information, (e) maintain boundaries, and (f) continue with life/activities. They also reported strategies for avoiding information, including removing or ignoring stimuli (e.g., avoiding people who might provide health advice) and controlling conversations (e.g., withholding information, changing the subject). Results suggest a link between previous experience with serious illness and health information avoidance. Building on uncertainty management theory, this study demonstrated that health information avoidance is situational, relatively common, not necessarily unhealthy, and may be used to accomplish multiple communication goals.

News media literacy refers to the knowledge and motivations needed to identify and engage with journalism. This study measured levels of news media literacy among 500 teenagers using a new scale measure based on Potter’s model of media literacy and adapted to news media specifically. The adapted model posits that news media literate individuals think deeply about media experiences, believe they are in control of media’s influence, and have high levels of basic knowledge about media content, industries and effects. Based on measures developed to assess news media literacy, highly news literate teens were found to be more intrinsically motivated to consume news, more skeptical and more knowledgeable about current events than their less news literate counterparts.

The hypothesis that early flowering plants were insect-pollinated could be tested by an examination of the pollination biology of basal angiosperms and the pollination modes of fossil angiosperms. We provide data to show that early fossil angiosperms were insect-pollinated. Eighty-six percent of 29 extant basal angiosperm families have species that are zoophilous (of which 34% are specialized) and 17% of the families have species that are wind-pollinated, whereas basal eudicot families and basal monocot families more commonly have wind and specialized pollination modes (up to 78%). Character reconstruction based on recent molecular trees of angiosperms suggests that the most parsimonious result is that zoophily is the ancestral state. Combining pollen ornamentation, size, and aperture characteristics and the abundance of single-species pollen clumps of Cenomanian angiosperm-dispersed pollen species from the Dakota Formation demonstrates a dominance of zoophilous pollination (76% versus 24% wind pollination). The zoophilous pollen species have adaptations for pollination by generalist insects (39%), specialized pollen-collecting insects (27%), and other specialized pollinators (10%). These data quantify the presences of more specialized pollination modes during the mid-Cretaceous angiosperm diversification.

In this manuscript, The Swedish Adoption/Twin Study of Aging (SATSA) is described. Although the study is a multidisciplinary program in gerontological genetics, the summary of findings focuses on the cognitive measures. In the second part of the manuscript, we investigate the role played by measures of processing speed in explaining the longitudinal trajectories of change for cognitive abilities and the genetic and environmental influences on those trajectories. When processing speed was regressed out of cognitive measures representing three cognitive domains (crystallized, fluid, and memory) and a general cognitive factor, the trajectory of decline was less severe. Quantitative genetic analyses indicated that environmental variance increases in late adulthood. A substantial portion of the genetic variance for these cognitive abilities was accounted for by genetic variance for speed. With increasing age, genetic variance associated with processing speed becomes a more prominent component of genetic variance for fluid abilities and for the general cognitive factor.

We investigate the intersection of social media and the workplace, focusing on job performance impacts of employees' social media addictions and social media reactions through work-family balance and burnout. The research model is grounded in conservation of resources theory, which suggests social media compulsions and emotional reactions to co-worker's social media posts will deplete employees' energetic and constructive resources, making it difficult to achieve work-family balance and increasing the likelihood of job burnout, and will ultimately degrade job performance. A sample of 326 full-time employees revealed a negative relationship between social media addiction and work-family balance and a positive relationship between social media reactions and job burnout. Balance and burnout mediated the relationship between social media and job performance such that social media addiction was negatively related to job performance through work-family balance, and social media reactions were negatively related to performance through burnout and work-family conflict.

The Stanford-Binet Intelligence Scale: Fifth Edition (SB5) is an intelligence assessment that was created to evaluate an individual's intellectual capacity. The targeted age ranges from 2–85+ years old. The scores that are obtained through this assessment are: Full Scale IQ Scores, Abbreviated Battery Scores, Verbal IQ Scores, and Nonverbal IQ Scores. This test takes approximately 45–75 minutes to administer. Scores acquired through this assessment can be used for a variety of purposes, including: educational program admission, eligibility for special education, and/or eligibility for gifted programs.

Psychological entitlement is a relatively stable tendency toward inflated self-perceptions and unrealistic expectations concerning praise and rewards. This study investigates two behavioral outcomes of entitlement — political behavior and co-worker abuse — and the mediating role of job-related frustration. We also examine the impact of supervisor communication (i.e. evaluative and informative communication) on the relationship between psychological entitlement and frustration. Results of a study of 223 employees suggested that entitlement was positively associated with both political behavior and co-worker abuse, and that frustration partially or fully mediated both relationships. Additionally, results suggested that relatively high levels of supervisor communication reduced job frustration for less-entitled employees but exacerbated the frustration reported by those with stronger entitlement perceptions.

Latent growth models were applied to data from the Swedish Adoption/Twin Study of Aging to discover if the rate of change in cognitive performance increased from middle age to later adulthood. The sample included 590 participants aged 44 to 88 years at first measurement. Data were gathered at 2 follow-up occasions at intervals of 3 years. Cognitive ability was assessed through 11 tests that tapped crystallized, fluid, memory, and spatial abilities and perceptual speed. Results indicated stability for measures of crystallized ability, linear age changes for many cognitive abilities, and a significant acceleration in linear decline after age 65 for measures with a large speed component. Gender differences were found only in mean level, not in rate of decline.

The positive relationship between perceptions of politics and strain has received a great deal of confirmation in the literature. What has been missing from these studies is a search for variables that minimize the negative outcomes associated with this relationship. In an effort to fill this void, the present paper investigated three possible moderators of the relationship between perceptions of politics and strain: leader–member exchange, participative decision‐making, and communication with supervisors. Results from a sample consisting of 1,255 respondents from two different organizations provided support for the buffering effect of supervisor variables on the perceptions of politics and strain relationship.

Abstract Despite renewed interest in news literacy (NL) as a way to combat mis- and dis-information, existing scholarship is plagued by insufficient theory building and inadequate conceptualization of both “NL” and its application. We address this concern by offering a concise definition of NL and suggest five key knowledge and skill domains that comprise this literacy. We distinguish NL from its application to behaviors that communication scholars have been interested in, including news exposure, verification, and identifying misinformation. We propose an adapted Theory of Planned Behavior (TPB) to include NL in addition to the existing components (attitudes towards the behavior, social norms, perceived behavioral control) when modeling NL Behaviors. We discuss how this model can unite scholars across subfields and propose a research agenda for moving scholarship forward.
