The Connection Between Cyberbullying and Teenage Suicide: An Honors Thesis

The act of bullying within school systems has existed for a very long time; so long that there are decades of research that investigate the negative psychological impacts of bullying. However, currently, bullying has taken on a cyber form thanks to the invention of the internet and all the social media apps that follow. Young adolescents are using social media apps like Facebook, Twitter, Tumblr, and Instagram to keep in constant contact with each other, but bullies have used this tool as another way to harass their victims and send cruel and threatening messages to their victims. Within the last fifteen years, cyberbullying has gained increased coverage in the news, especially when teenagers end their own lives following excessive bullying online and by text messages. In response, research has been conducted on cyberbullying and suicide, and legislation has been developed to regulate and establish consequences for cyberbullying. This thesis provides a systematic literature review of research that has been done on cyberbullying and suicide. It begins by defining cyberbullying and presenting some nationally publicized cases in which cyberbullying appeared to play a role in the victims’ suicide. Next, characteristics of the bullies, as well as their motivations, are considered. Research on the relations between cyberbullying and suicide are then reviewed, with a discussion of limitations of these studies. Finally, a discussion of how the media have reported incidents of cyberbullying and suicide is provided, followed by a consideration of some of the school and legal policies concerning cyberbullying. With this thesis, I hope to bring more awareness of the issue of cyberbullying and inspire further scientific research as well as legal action and changes within schools

Alliance of Genome Resources Portal: unified model organism research platform

The Alliance of Genome Resources (Alliance) is a consortium of the major model organism databases and the Gene Ontology that is guided by the vision of facilitating exploration of related genes in human and well-studied model organisms by providing a highly integrated and comprehensive platform that enables researchers to leverage the extensive body of genetic and genomic studies in these organisms. Initiated in 2016, the Alliance is building a central portal (www.alliancegenome.org) for access to data for the primary model organisms along with gene ontology data and human data. All data types represented in the Alliance portal (e.g. genomic data and phenotype descriptions) have common data models and workflows for curation. All data are open and freely available via a variety of mechanisms. Long-term plans for the Alliance project include a focus on coverage of additional model organisms including those without dedicated curation communities, and the inclusion of new data types with a particular focus on providing data and tools for the non-model-organism researcher that support enhanced discovery about human health and disease. Here we review current progress and present immediate plans for this new bioinformatics resource

The chimerical genome of Isla del Coco feral pigs (Costa Rica), an isolated population since 1793 but with remarkable levels of diversity

The history of domestic species and of their wild ancestors is not a simple one, and feral processes can clarify key aspects of this history, including the adaptive processes triggered by new environments. Here, we provide a comprehensive genomic study of Isla del Coco (Costa Rica) feral pigs, a unique population that was allegedly founded by two individuals and has remained isolated since 1793. Using SNP arrays and genome sequencing, we show that Cocos pigs are hybrids between Asian and European pigs, as are modern international pig breeds. This conclusively shows that, as early as the 18th century, British vessels were loading crossbred pigs in Great Britain and transporting them overseas. We find that the Y chromosome has Asian origin, which has not been reported in any international pig breed. Chinese haplotypes seem to have been transmitted independently between Cocos and other pig breeds, suggesting independent introgression events and a complex pattern of admixing. Although data are compatible with a founder population of N = 2, variability levels are as high in Cocos pigs as in international pig breeds (~1.9 SNPs/kb) and higher than in European wild boars or local breeds (~1.7 SNPs/kb). Nevertheless, we also report a 10-Mb region with a marked decrease in variability across all samples that contains four genes (CPE, H3F3C, SC4MOL and KHL2) previously identified as highly differentiated between wild and domestic pigs. This work therefore illustrates how feral population genomic studies can help to resolve the history of domestic species and associated admixture events.EB is the recipient of a PhD fellowship from the Ministry of Science (Spain).

Anaesthetic neurotoxicity and neuroplasticity:an expert group report and statement based on the BJA Salzburg Seminar

<p>Although previously considered entirely reversible, general anaesthesia is now being viewed as a potentially significant risk to cognitive performance at both extremes of age. A large body of preclinical as well as some retrospective clinical evidence suggest that exposure to general anaesthesia could be detrimental to cognitive development in young subjects, and might also contribute to accelerated cognitive decline in the elderly. A group of experts in anaesthetic neuropharmacology and neurotoxicity convened in Salzburg, Austria for the BJA Salzburg Seminar on Anaesthetic Neurotoxicity and Neuroplasticity. This focused workshop was sponsored by the British Journal of Anaesthesia to review and critically assess currently available evidence from animal and human studies, and to consider the direction of future research. It was concluded that mounting evidence from preclinical studies reveals general anaesthetics to be powerful modulators of neuronal development and function, which could contribute to detrimental behavioural outcomes. However, definitive clinical data remain elusive. Since general anaesthesia often cannot be avoided regardless of patient age, it is important to understand the complex mechanisms and effects involved in anaesthesia-induced neurotoxicity, and to develop strategies for avoiding or limiting potential brain injury through evidence-based approaches.</p>
