    Today social media is rapidly growing. Many social media users, specifically Instagram users, are from the Millennial generation (born between 1982 and 1999), and Generation-Z (born between 2000 and 2020) (knoema.com, 2020). They love to share their life through social media, especially by posting and viewing others’ photos and videos on Instagram. Celebrity endorsement of products and brands has shown to increase both brand awareness and sales for companies. The purpose of this study is to investigate social media influence of celebrities on consumers’ brand choices. A conceptual model is developed to investigate the influences of physical attractiveness, celebrity credibility, celebrity-brand congruence, celebrity’s activeness on social media, perceived brand credibility, and a consumers’ attitude towards the brand being endorsed and intentions to choose a celebrity-endorsed brand. The findings of this study will add knowledge to the field of celebrity endorsements on social media, with regard to the Generation-Z and Millennial generations

    Seeing the Forest and the Trees: Exploring the Impact of Inter- and Intra-Entrepreneurial Ecosystem Embeddedness on New Venture Creation

    Research on entrepreneurial ecosystems (EEs) has tended to focus on the role that characteristics internal to the EE play in determining EE-level outcomes. Notwithstanding the insights that academics, policy-makers, and entrepreneurs have gleaned from these studies, prior research has yet to explain whether, how, and why these outcomes might also be impacted by an EE's position within the larger network of EEs. Given broad acceptance for the important role that networks play in facilitating entrepreneurship at the firm level, we contend that adopting a network-based view of EEs may also help predict and explain aggregate entrepreneurial outcomes at the EE level. Specifically, we adopt a double embeddedness lens to examine the impact of both inter-EE (i.e., structural embeddedness) and intra-EE (i.e., cultural embeddedness) factors on EE-level new venture creation. Using a longitudinal sample of regional data in the United States from 1994 to 2016, we develop and test hypotheses where the relationship between structural embeddedness and new venture creation follows an inverted "U" shape that is itself moderated by cultural embeddedness. We conclude by discussing how these findings informtheory and practice in this area.</p

    The aphid transmitted Polerovirus Turnip yellows virus (TuYV) was found to be widespread with high incidences in oilseed rape (OSR) across Europe. UK, France, Germany and Poland all having >90% TuYV incidence in some OSR crops. From the 179 whole TuYV genomes sequenced in this study the phylogenetic analyses indicated three distinct genetic groups in the UK, two of which were also detected in Europe. These three genotypes were also distinct from the original sequenced TuYV-FL. These groups are proposed to be distinct species due to their genetic distance based on the most variable gene ORF5 and phylogenetic analyses of ORF1, ORF3, ORF4 and ORF5. Mixed TuYV infection was uncommon and only two plant samples had genetically distinct isolates. Whole genome analysis also provided valuable information on two recombination hotspots located within TuYV genes ORF3 and ORF5. Investigation into the epidemiology of TuYV revealed many weed and crop species as hosts, including sugar beet, which it was previously thought not to infect. TuYV isolates detected infecting weed plants in the UK were successfully transmitted to OSR. Previously undescribed hosts, verbascum, geranium, teasel, spear thistle, dock and previously described hosts in the Brassicaceae, Compositae and Lepidium families were found in the UK. A full-length infectious clone of a UK isolate of TuYV has been produced, this will allow further assessment of TuYV in the future. The infectious clone was able to cause systemic infection of TuYV and was aphid transmissible. The Arabidopsis thaliana gene knock-out study did not reveal a single eIF gene or gene linked to virus movement or silencing that could provide extreme broad-spectrum resistance. The gene eIF(iso)4G.1 was able to give a broad-spectrum quantitative resistance, and the potential of eIF3D.2 as well as sucrose symporters SUC1 and SUC2 as candidates for extreme TuYV resistance were discovered. This understanding of the epidemiology and diversity of TuYV is being used to develop strategies for control

    To get out of the building or not? That is the question: The benefits (and costs) of customer involvement during the startup process

    This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.Nascent entrepreneurs are frequently advised to “get out of the building” and consult with customers before any serious efforts to develop a new product or service are undertaken so they can understand what their potential customers really want/need. Despite the intuitive nature of this advice, it lacks theoretical and empirical bases. As such, the worldwide popularity of the movements this approach has spawned, such as Customer Development and Lean Startup, seems to rest on the unfounded assumption that the benefits of involving customers outweighs the costs. Thus, we theorize about the pros and cons of involving customers early on in the startup process and empirical test our model using data from the PSED II. Our findings suggest that while involving customers early will help entrepreneurs create offerings customers are willing to pay for, it also results in potentially costly delays in the launch of those offerings. We also find that these benefits and costs are magnified when innovativeness is high

    Social Impact Measurement: Current Approaches and Future Directions for Social Entrepreneurship Research

    Full text link
    Despite the importance of social impact to social entrepreneurship research, standards for measuring an organization’s social impact are underdeveloped on both theoretical and empirical grounds. We identify a sample of 71 relevant papers from leading (FT50) business journals that examine, conceptually or empirically, the measurement of social impact. We first describe the breadth of definitions, data sources, and operationalizations of social impact. Based on this analysis, we generate a typology of four approaches to conceptualizing social impact, which we use to organize insights and recommendations regarding improved measurement of the social impact of entrepreneurial ventures

    OBJECTIVE: To understand preferences for features of weight loss programs among adults with or at risk of type 2 diabetes in the U.K. RESEARCH DESIGN AND METHODS: We conducted a discrete choice experiment with 3,960 U.K. adults living with overweight (n = 675 with type 2 diabetes). Preferences for seven characteristics of weight loss programs were analyzed. Simulations from choice models using the experimental data predicted uptake of available weight loss programs. Patient groups comprising those who have experience with weight loss programs, including from minority communities, informed the experimental design. RESULTS: Preferences did not differ between individuals with and without type 2 diabetes. Preferences were strongest for type of diet. Healthy eating was most preferred relative to total diet replacement (odds ratio [OR] 2.24; 95% CI 2.04–2.44). Individual interventions were more popular than group interventions (OR 1.40; 95% CI 1.34–1.47). Participants preferred programs offering weight loss of 10–15 kg (OR 1.37; 95% CI 1.28–1.47) to those offering loss of 2–4 kg. Online content was preferred over in-person contact (OR 1.24; 95% CI 1.18–1.30). There were few differences in preferences by gender or ethnicity, although weight loss was more important to women than to men, and individuals from ethnic minority populations identified more with programs where others shared their characteristics. Modeling suggested that tailoring programs to individual preferences could increase participation by ∼17 percentage points (68% in relative terms). CONCLUSIONS: Offering a range of weight loss programs targeting the preferred attributes of different patient groups could potentially encourage more people to participate in weight loss programs and support those living with overweight to reduce their weight

    Get PDF
    Aims:To identify key research questions where answers could improve care for older people living with diabetes (PLWD), and provide detailed recommendations for researchers and research funders on how best to address them.Methods:A series of online research workshops were conducted, bringing together a range of PLWD and an acknowledged group of academic and clinical experts in their diabetes care to identify areas for future research. Throughout the pre-workshop phase, during each workshop, and in manuscript preparation and editing, PLWD played an active and dynamic role in discussions as part of both an iterative and narrative process.Results:The following key questions in this field were identified, and research recommendations for each were developed:How can we improve our understanding of the characteristics of older people living with diabetes (PLWD) and their outcomes, and can this deliver better person-centred care?How are services to care for older PLWD currently delivered, both for their diabetes and other conditions? How can we optimise and streamline the process and ensure everyone gets the best care, tailored to their individual needs?What tools might be used to evaluate the level of understanding of diabetes in the older population amongst non-specialist Healthcare Professionals (HCPs)?How can virtual experts or centres most effectively provide access to specialist multi-disciplinary team (MDT) expertise for older PLWD and the HCPs caring for them?Is a combination of exercise and a nutrition-dense, high protein diet effective in the prevention of the adverse effects of type 2 diabetes and deterioration in frailty, and how might this be delivered in a way which is acceptable to people with type 2 diabetes?How might we best use continuous glucose monitoring (CGM) in older people and, for those who require support, how should the data be shared?How can older PLWD be better empowered to manage their diabetes in their own home, particularly when living with additional long-term conditions?What are the benefits of models of peer support for older PLWD, both when living independently and when in care?Conclusions:This paper outlines recommendations supported by PLWD through which new research could improve their diabetes care and calls on the research community and funders to address them in future research programmes and strategies
