Post-AGB Stars in Globular Clusters and Galactic Halos
We discuss three aspects of post-AGB (PAGB) stars in old populations. (1) HST
photometry of the nucleus of the planetary nebula (PN) K 648 in the globular
cluster (GC) M15 implies a mass of 0.60 Msun, in contrast to the mean masses of
white dwarfs in GCs of ~0.5 Msun. This suggests that K 648 is descended from a
merged binary, and we infer that single Pop II stars do not produce visible
PNe. (2) Yellow PAGB stars are the visually brightest stars in old populations
(Mv ~ -3.3) and are easily recognizable because of their large Balmer jumps;
thus they show great promise as a Pop II standard candle. Two yellow PAGB stars
in the GC NGC 5986 have the same V magnitudes to within +/-0.05 mag, supporting
an expected narrow luminosity function. (3) Using CCD photometry and a u filter
lying below the Balmer jump, we have detected yellow PAGB stars in the halo of
M31 and in its dwarf elliptical companion NGC 205. With the Milky Way zero
point, we reproduce the Cepheid distance to M31, and find that NGC 205 is ~100
kpc further away than M31. The star counts imply a yellow PAGB lifetime of
about 25,000 yr, and their luminosities imply masses near 0.53 Msun.Comment: 6 pages, 2 figures. To appear in proceedings of Torun, Poland,

XVIII SIM Conference Presentation - Social Media Influencers (SMIs) in Context: a literature review
This review focused on three main areas, âSocial Media Influencers (SMIs) in Context, The Impact of SMIs on Adolescents, and Consumer Behaviour in a Digital Era â Generation Z in Perspective.â This article aims to further the overall understanding of SMIs and outlines the impact of SMIs on adolescentsâ lives. Thus, the main objective of this literature review is to raise awareness within the marketing field about the influence of social media influencers on adolescents and how brands promote their products and content through social media influencers. The review comprised a deep search using electronic journal databases and secondary data from reports, surveys, and empirical research. The main findings from this review are insights about who social media influencers are, how to recognise them, how they impact adolescentsâ lives, how brands and SMIs are partnering
Exploring Research Methods Workshop Presentation TU Dublin - An investigation of the Personality Traits That Could Identify Vulnerable Young People Who Will be Susceptible to Undue Influence by Social Media Influencers (SMIs)
This study aims to further the overall understanding of Social Media Influencers (SMIs) and to specifically predict who will be susceptible to influence by them. The main objective of this research relies on to determine whether there is a specific personality profile that predisposes young people to undue influence by social media influencers. Based on previous research published by the journal Frontiers in Psychology titled âThe Role of Social Media Influencers in the Lives of Children and Adolescents 1â, a list of potentially harmful content will be compiled. Participants (N=40) in phase one will then be given a standard test of personality and will also complete a short questionnaire asking them about their online browsing habits and to list their top five social media influencers. The content of the most popular influencers will be analysed. Statistical analysis based on personality testsâ results will then be conducted to assess whether there are specific personality traits or personality profiles that are associated with being susceptible to undue influence. The results from phase one will be employed to develop a teaching module that will be delivered to a separate sample of N=40 young people. The purpose of the module will be to develop critical thinking skills and shield against undue influence by SMIs. Finally, post presentation of the module, half of participants (N=20) will be invited to attend a semi-structured interview aiming to understand their perceptions of the module and how effective they believe it was (total sample = 80, 40 males and 40 females)

An Ethical Discussion About the Responsibility for Protection of Minors in the Digital Environment: A State-of-the-art review
Many ethical questions have been raised regarding the use of social media and the internet, mainly related to the protection of young people in the digital environment. In order to critically address the research question who is responsible for ethically protecting minors in the digital environment? , this paper will review the main literature available to understand the role of parents, the government, and companies in protecting young people within the digital environment. We employed a holistic process that covers a state-of-the-art review and desk research. The article is divided into four sessions; (1) Government Policies from the European Union (EU) Perspective; (2) Parental Control; (3) An Overview of Companies and the Private and Self-Regulation Sectors; and (4) the Ethical Dilemma. Throughout, we reviewed specific topics regarding the potentially harmful content for young people within the digital environment, questioned how ethical concerns shape content and interactions online and discussed how internet parenting styles impact risks and opportunities for young people in the digital world. Finally, we analysed the research question contrasting it with the main findings in this review and offered recommendations
