The paradox of technology: Negativity bias in consumer adoption of innovative technologies

alexandrossfakianakis shared this article with you from Inoreader The paradox of technology: Negativity bias in consumer adoption of innovative technologies via Psychology & Marketing Abstract Innovative technologies often feature inherently conflicting properties. This poses a challenge for marketers because negative properties not only weigh heavily on consumers' technology adoption decisions but potentially do more so than positive ones. To shed light on the paradox of technology and its underlying processes, the present research develops a conceptual model drawing on technology adoption and valence perception theories about the prevalence of negativity bias in consumers' technology adoption decisions with its unique effect through the serial chain of consumers' perceptions of risk and trust regarding the technology. Results of three studies (N = 1309) demonstrate that the effect of negative valence consistently outperforms that of positive valence in consumers' technology adoption intentions (Studies 1–2) and decisions (Study 3). Furthermore, results show that the disproportionate effect of negative (vs. positive) valence can be expl ained by the proposed serial causal chain through consumers' perception of risk of the technology and trust in the technology (Studies 2–3) while ruling out company trust and consumer knowledge as alternative drivers of the effects (Study 3). These findings contribute to the pertinent literature on consumer psychology in decisions to adopt novel technologies in that they quantify and explain the potential outcome stemming from the ambiguous properties of novel technology. Moreover, this study finds negativity bias to be an often overlooked consumer bias with implications for marketing practice and useful for understanding and lowering resistance towards artificial intelligence technology.

Shared understanding and social connection: Integrating approaches from social psychology, social network analysis, and neuroscience

alexandrossfakianakis shared this article with you from Inoreader Shared understanding and social connection: Integrating approaches from social psychology, social network analysis, and neuroscience via Social and Personality Psychology Compass Abstract Meaningfully connecting with others is critical to the well-being of individuals. What phenomena contribute to and stem from social connection? In this paper, we integrate emerging work that uses neuroimaging and social network analysis with theories that explore the links between shared reality and social connection. We highlight recent work suggesting that the extent to which people have aligned mental processing and shared subjective construals to those around them—as shown by neural similarity—is associated with both objective and subjective social connection. On the other hand, idiosyncrasies are linked to difficulties with social connection. We conclude by suggesting how the links between shared understanding and social connection can be productively used as a framework to study psychosocial phenomena of interest. View on Web

Posterior nasal neurectomy for intractable rhinitis: a systematic review of the literature

alexandrossfakianakis shared this article with you from Inoreader Posterior nasal neurectomy for intractable rhinitis: a systematic review of the literature via Clinical Otolaryngology Abstract Background Rhinitis affects up to 40% of the population worldwide and can significantly reduce quality of life. Some patients remain symptomatic despite maximal medical therapy. In refractory cases, posterior nasal neurectomy (PNN - the endoscopic division of the intranasal nerve branches containing postganglionic parasympathetic fibres) is postulated to reduce symptom burden. Objectives of review To establish whether PNN is effective and safe in the management of allergic and non-allergic rhinitis. Type of review Systematic review Methods A comprehensive literature search was undertaken using PubMed, EMBASE, MEDLINE, and Cochrane. The inclusion criteria were: studies published in English, studies where PNN was performed either with or without additional procedures, and where measures of objective/subjective outcomes and/or complications were reported. Extracted data included study type, sample size, surgical technique, study population characteristics, follow-up period, outcome measures, complications of surgery, and symptom outcomes. Results Twenty-three articles satisfied the inclusion criteria studying in total 2282 patients. Sample size ranged from 8-1056. There were three randomised controlled trials, three case control studies, and the remaining seventeen were case series using both objective and subjective outcome measures. All but one study found improved patient reported outcomes following PNN. Complications were reported in 14 studies - epistaxis was the most common complication and was observed in 30 patients (1.5% of subjects). Conclusions Posterior nasal neurectomy had a low rate of complications. Although most studies reported significant symptomatic improvement, their heterogeneity, level of evidence, study design, and/or quality was not sufficient to draw any firm conclusions on the effectiveness of the procedure. Larger, well designed studies are needed to clarify its role in the management of difficult-to-treat rhinitis. This article is protected by copyright. All rights reserved. View on Web

Long-term Traffic-related Air Pollutant Exposure and Amyotrophic Lateral Sclerosis Diagnosis in Denmark: A Bayesian Hierarchical Analysis

alexandrossfakianakis shared this article with you from Inoreader Long-term Traffic-related Air Pollutant Exposure and Amyotrophic Lateral Sclerosis Diagnosis in Denmark: A Bayesian Hierarchical Analysis via Epidemiology - Current Issue Background: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. Limited evidence suggests ALS diagnosis may be associated with air pollution exposure and specifically traffic-related pollutants. Methods: In this population-based case–control study, we used 3,937 ALS cases from the Danish National Patient Register diagnosed during 1989–2013 and matched on age, sex, year of birth, and vital status to 19,333 population-based controls free of ALS at index date. We used validated predictions of elemental carbon (EC), nitrogen oxides (NOx), carbon monoxide (CO), and fine particles (PM2.5) to assign 1-, 5-, and 10-year average exposures pre-ALS diagnosis at study participants' present and historical residential addresses. We used an adjusted Bayesian hierarchical conditional logistic model to estimate individual pollutant associations and joint and average associations for traffic-related pollutants (EC, NOx, CO). Results: For a standard deviation (SD) increase in 5-year average concentrations, EC (SD = 0.42 µg/m3) had a high probability of individual association with increased odds of ALS (11.5%; 95% credible interval [CrI] = –1.0%, 25.6%; 96.3% posterior probability of positive association), with negative associations for NOx (SD = 20 µg/m3) (–4.6%; 95% CrI = 18.1%, 8.9%; 27.8% posterior probability of positive association), CO (SD = 106 µg/m3) (–3.2%; 95% CrI = 14.4%, 10.0%; 26.7% posterior probability of positive association), and a null association for nonelemental carbon fine particles (non-EC PM2.5) (SD = 2.37 µg/m3) (0.7%; 95% CrI = 9.2%, 12.4%). We found no association between ALS and joint or average traffic pollution concentrations. Conclusions: This study found high probability of a positive association between ALS diagnosis and EC concentration. Further work is needed to understand the role of traffic-related air pollution in ALS pathogenesis. View on Web

Gestational Hypertensive Disorders and Maternal Breast Cancer Risk

alexandrossfakianakis shared this article with you from Inoreader Gestational Hypertensive Disorders and Maternal Breast Cancer Risk in a Nationwide Cohort of 40,720 Parous Women via Epidemiology - Current Issue Background: Preeclampsia and gestational hypertension are hypothesized to be associated with reduced maternal breast cancer risk, but the epidemiologic evidence is inconclusive. Our objective was to examine associations between gestational hypertensive disorders and breast cancer in a nationwide cohort of women with a family history of breast cancer. Methods: Women ages 35–74 years who had a sister previously diagnosed with breast cancer, but had never had breast cancer themselves, were enrolled in the Sister Study from 2003 to 2009 (N = 50,884). At enrollment, participants reported diagnoses of eclampsia, preeclampsia, or gestational hypertension in each pregnancy. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between history of a gestational hypertensive disorder and incident invasive breast cancer or ductal carcinoma in situ among 40,720 parous women. We used age as the time scale and adjusted for birth cohort, race–ethnicity, and reproductive, socioeconomic, and behavioral factors. We examined effect measure modification by risk factors for gestational hypertensive disease and breast cancer and assessed possible etiologic heterogeneity across tumor characteristics. Results: The prevalence of gestational hypertensive disease was 12%. During follow-up (mean = 10.9 years), 3,198 eligible women self-reported a breast cancer diagnosis. History of a gestational hypertensive disorder was not associated with breast cancer risk (HR = 1.0; 95% CI = 0.90, 1.1). We did not observe clear evidence of effect measure modification or etiologic heterogeneity. Conclusions: History of a gestational hypertensive disorder was not associated with breast cancer risk in a cohort of women with a first-degree family history of breast cancer. View on Web
