Motives for Facebook use in an Australian sample

A survey of 209 Australians (17-69 years) was conducted to examine the motives for Facebook use, and how these factors related to individuals' belonging, self-esteem, control, and meaning. An initial factor analysis identified four distinct factors underlying motives for Facebook use: meeting people, relationship maintenance, monitoring relationships, and seeking information. These four factors extend previous research and help clarify the key reasons for Facebook use. Further analyses found that participants' age was negatively correlated with each of the motives for Facebook use factors. Multiple regressions were performed with each of the four motives regressed on age, gender, and the individuals' belonging, self-esteem, control, and meaning. All four of these variables contributed significantly to the prediction of factor 1 (meeting people). Only belonging was a significant predictor of factor 2 (relationship maintenance) and factor 3 (monitoring relationships). Both self-esteem and belonging were significant predictors of factor 4 (seeking information). This study included general community members and not just undergraduate students and therefore has wider applicability than previous research. Facebook use seems to be closely related to individuals' belonging across a wide age range

From ‘likes’ to unfriending: the need to belong and relational information on Facebook

Humans are fundamentally social creatures, interacting with other people through face-to-face interactions and through the use of social media. According to the theoretical framework of the need to belong, interactions that are stable across time, and provide support and encouragement are necessary for people to psychologically thrive. Therefore, threats to belonging pose a serious issue. Theoretically, when a person experiences a threat to their belonging, this then results in preferential processing of social cues relevant to relational information. While copious amounts of research have investigated the social cues that guide face-to-face interactions, to date, very little research has explored the social cues that provide relational information on Facebook, currently the largest social networking site. Therefore, the overall aim of this program of research is to use a mixed-method design to explore and understand the social cues that impart relational information on Facebook, specifically the social cues that indicate potential rejection and acceptance. From the Study 1 qualitative findings, there were a number of social cues identified which underpinned 3 main themes of relational information, that is, social inclusion, social exclusion, and social comparison. Study 2 demonstrated that the social cues identified in Study 1 were generalisable to a wider population. Together, these results highlighted specific social cues, such as ‘likes’ which provided relational information relevant to both rejection and acceptance. Furthermore, Study 2 also identified four different motivations that people have for using Facebook, as well as establishing that need to belong and age are significant predictors for these motivations. Finally, Study 3 took an innovative approach regarding experimental design and Facebook, with the development of artificial Facebook pages that incorporated the social cues identified in Studies 1 and 2. This then enabled investigation into the salience of the social cues after participants received either a threat to their need to belong or an affirmation of their relational worth. There were no differences found between the two conditions and the recall of social cues and neutral information. Furthermore and contrary to theoretical expectations, when the social cues were further broken down into social cues of rejection and acceptance, only Experiment 2 demonstrated a significant difference between the two conditions and the recall of social rejection cues. This thesis uniquely contributes to new knowledge in a number of ways. Firstly, this research provides comprehensive information regarding the identification of social cues that communicate relational information on Facebook. Additionally, Study 2 provides compelling evidence of the need to belong as a predictor of the motivations for Facebook use. Moreover, this research offers a unique method of investigating social cues on Facebook through the development of artificial Facebook pages. Finally, this program of research extends the existing literature on the need to belong and social monitoring to the on-line social environment, and subsequently finds that the very nature of the on-line environment means that the available social cues may be more subtle and more complex than ever imagined

Experiencing the Journey Together: The Role of Social Support during the Doctorate

Completing a doctorate can be a solitary and sometimes stressful experience, which is further exacerbated by the underlying nature and structure of this particular degree. The issue of social support during the doctoral journey is important to address given its relationship with well-being. Additionally, social isolation has been identified as a major contributing factor of compromised psychological and physical health. Indeed, adequate social support becomes a critical component if one is to successfully navigate the PhD terrain. This chapter will highlight the protective benefits associated with social support, as well as examine the empirical findings on the negative effects of social isolation during the doctoral journey. Additionally, this chapter will provide two contrasting student experiences of social isolation, specifically relating to on-campus versus off-campus modes of study. Finally, the provision of practical strategies to facilitate increased social support will be provided

Social media, rituals, and long-distance family relationship maintenance: a mixed-methods systematic review

For families with limited opportunities for face-to-face interaction, social media can be a vital communication medium to help shape the family identity, maintain bonds, and accomplish shared tasks. This mixed-methods systematic review of quantitative, qualitative, and mixed-method empirical studies published between 1997 and 2019, uses a convergent data-based framework to explore how long-distance families engage in family practices using various modes of social media. Fifty-one papers were synthesised into four domains: (1) doing family in a social media environment, (2) performing family through stories and rituals, (3) the nature of online communication practices, and (4) privacy, conflict, and the quality of family relationships. Given the value of patterned routines to families, research into the role of family kinkeepers is suggested. Finally, families use chat (messages) extensively for both assuring behaviour and conflict resolution so further investigation of the impact of this asynchronous mode is recommended

Evaluating the Effects of SARS-CoV-2 Spike Mutation D614G on Transmissibility and Pathogenicity.

Global dispersal and increasing frequency of the SARS-CoV-2 spike protein variant D614G are suggestive of a selective advantage but may also be due to a random founder effect. We investigate the hypothesis for positive selection of spike D614G in the United Kingdom using more than 25,000 whole genome SARS-CoV-2 sequences. Despite the availability of a large dataset, well represented by both spike 614 variants, not all approaches showed a conclusive signal of positive selection. Population genetic analysis indicates that 614G increases in frequency relative to 614D in a manner consistent with a selective advantage. We do not find any indication that patients infected with the spike 614G variant have higher COVID-19 mortality or clinical severity, but 614G is associated with higher viral load and younger age of patients. Significant differences in growth and size of 614G phylogenetic clusters indicate a need for continued study of this variant

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

Genomic assessment of quarantine measures to prevent SARS-CoV-2 importation and transmission

Mitigation of SARS-CoV-2 transmission from international travel is a priority. We evaluated the effectiveness of travellers being required to quarantine for 14-days on return to England in Summer 2020. We identified 4,207 travel-related SARS-CoV-2 cases and their contacts, and identified 827 associated SARS-CoV-2 genomes. Overall, quarantine was associated with a lower rate of contacts, and the impact of quarantine was greatest in the 16–20 age-group. 186 SARS-CoV-2 genomes were sufficiently unique to identify travel-related clusters. Fewer genomically-linked cases were observed for index cases who returned from countries with quarantine requirement compared to countries with no quarantine requirement. This difference was explained by fewer importation events per identified genome for these cases, as opposed to fewer onward contacts per case. Overall, our study demonstrates that a 14-day quarantine period reduces, but does not completely eliminate, the onward transmission of imported cases, mainly by dissuading travel to countries with a quarantine requirement

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant
