    BACKGROUND: Falls affect approximately one third of community-dwelling older adults each year and have serious health and social consequences. Fear of falling (FOF) (lack of confidence in maintaining balance during normal activities) affects many older adults, irrespective of whether they have actually experienced falls. Both falls and fear of falls may result in restrictions of physical activity, which in turn have health consequences. To date the relation between (i) falls and (ii) fear of falling with physical activity have not been investigated using objectively measured activity data which permits examination of different intensities of activity and sedentary behaviour. METHODS: Cross-sectional study of 1680 men aged 71-92 years recruited from primary care practices who were part of an on-going population-based cohort. Men reported falls history in previous 12 months, FOF, health status and demographic characteristics. Men wore a GT3x accelerometer over the hip for 7 days. RESULTS: Among the 12% of men who had recurrent falls, daily activity levels were lower than among non-fallers; 942 (95% CI 503, 1381) fewer steps/day, 12(95% CI 2, 22) minutes less in light activity, 10(95% CI 5, 15) minutes less in moderate to vigorous PA [MVPA] and 22(95% CI 9, 35) minutes more in sedentary behaviour. 16% (n = 254) of men reported FOF, of whom 52% (n = 133) had fallen in the past year. Physical activity deficits were even greater in the men who reported that they were fearful of falling than in men who had fallen. Men who were fearful of falling took 1766(95% CI 1391, 2142) fewer steps/day than men who were not fearful, and spent 27(95% CI 18, 36) minutes less in light PA, 18(95% CI 13, 22) minutes less in MVPA, and 45(95% CI 34, 56) minutes more in sedentary behaviour. The significant differences in activity levels between (i) fallers and non-fallers and (ii) men who were fearful of falling or not fearful, were mediated by similar variables; lower exercise self-efficacy, fewer excursions from home and more mobility difficulties. CONCLUSIONS: Falls and in particular fear of falling are important barriers to older people gaining health benefits of walking and MVPA. Future studies should assess the longitudinal associations between falls and physical activity

    B2B brands on Twitter: Engaging users with a varying combination of social media content objectives, strategies, and tactics

    Get PDF
    YesThe objective of this research is to increase understanding about B2B company-led user engagement on social media content. Building on hierarchy-of-effects (HoE) theory, we explore how the world’s leading B2B companies use content objectives (why), strategies (how), and tactics (what) on Twitter. We first integrate B2B advertising and social media research on companies’ content objectives, strategies, and tactics. Then, using qualitative analyses, we examine the existence of objectives, strategies, and tactics in the most engaging tweets (N=365) of the worlds’ ten leading B2B brands, covering five industries, in 2017. Finally, we quantitatively examine how the use of diverse objectives and strategies differs between the most engaging tweets (N=318) and least engaging tweets (N=229) of the companies in 2018. The companies use objectives, strategies and tactics that relate to creating awareness, knowledge and trust, interest, and liking in the majority of their most and least engaging tweets, and express preference, conviction and purchase aspects much less. Differences exist in general, industry-wise, and company-wise. The study is a rare attempt to integrate the extant B2B advertising and social media research, and compare the most and least engaging B2B social media content

    Consumers’ social media brand behaviors: uncovering underlying motivators and deriving meaningful consumer segments

    Get PDF
    The current research identifies the range of social media brand behaviors (i.e., brand touch points) that consumers can exhibit on social media, and subsequently queries a representative sample of consumers with regard to such behaviors. The analysis reveals four underlying motivators for consumers’ social media behaviors, including brand tacit engagement, brand exhibiting, brand patronizing and brand deal seeking. These motivators are used to derive meaningful consumer segments identified as content seekers, observers, deal hunters, hard-core fans, posers and respectively patronizers, and described through co-variates including brand loyalty, brand attachment and social media usage. The findings are critically discussed in the light of literature on the needs that consumers meet through brand consumption and on the types of relationships consumers build with brands. Not least, the managerial implications of the current findings are debated

    On the optimal marketing aggressiveness level of C2C sellers in social media: evidence from China

    Get PDF
    Social media has become a widely used marketing tool for reaching potential customers. Because of its low cost, social media marketing is especially appealing to customer-to-customer (C2C) sellers. Customers can also benefit from social media marketing by learning about products and by interacting with sellers in real time. However, a seller's marketing microblogs may backfire on her for dominating the social space. Defining the marketing popularity as the average number of likes each seller receives per marketing-related microblog and defining the marketing aggressiveness level as the proportion of her marketing-related microblogs, this paper empirically quantifies the optimal level of marketing aggressiveness in social media to achieve the maximum popularity. We gather the data from China's largest microblogging platform, Sina Weibo, and the sellers in our sample are from China's largest C2C online shopping platform, Taobao. We find that the empirical relationship between the marketing aggressiveness level and the marketing popularity follows an inverted U-shape curve, where the optimal level is around 30%. In addition, we find a saturation effect of the number of followers on marketing popularity after it reaches around 100,000. Our findings imply that social media marketing should not overlook customers' social needs. Our measure of marketing aggressiveness provides a dynamic business metric for practitioners to monitor so as to improve their marketing and managerial decision making process

    Social media marketing strategy: definition, conceptualization, taxonomy, validation, and future agenda

    Although social media use is gaining increasing importance as a component of firms’ portfolio of strategies, scant research has systematically consolidated and extended knowledge on social media marketing strategies (SMMSs). To fill this research gap, we first define SMMS, using social media and marketing strategy dimensions. This is followed by a conceptualization of the developmental process of SMMSs, which comprises four major components, namely drivers, inputs, throughputs, and outputs. Next, we propose a taxonomy that classifies SMMSs into four types according to their strategic maturity level: social commerce strategy, social content strategy, social monitoring strategy, and social CRM strategy. We subsequently validate this taxonomy of SMMSs using information derived from prior empirical studies, as well with data collected from in-depth interviews and a quantitive survey among social media marketing managers. Finally, we suggest fruitful directions for future research based on input received from scholars specializing in the field
