The Charlie Hebdo attacks fueled an online debate over freedom of expression and religion, whereas the purpose of social media evolved into a humanitarian one following the November 13 attacks in Paris. This research looks into the individual evolutions of the related hashtags that surfaced in 2015, including #JeSuisCharlie (and its opposites, such as #JeNeSuisPasCharlie), #DonDuSang, #PorteOuverte and #RechercheParis, among others. Another research point was with the September 11 attacks—with the 9/11 attacks against the United States, few to no channels were available for the kind of immediate discussions and support seen after the Paris attacks. After spending time in Paris during the spring 2015 semester and researching the aftermath of the Charlie Hebdo attacks and the history of the publication, the conclusion rests on the idea that the online discussions perpetuated by both supporters and dissenters of the magazine contribute to a more robust, open democracy supported by these social media platforms.
A portion of this thesis also delves into the parallels and differences between the American First Amendment and the French free speech laws—all of which pertain to the Charlie Hebdo content and the online responses to the 2015 Paris attacks.
The interviews conducted include a French art history professor at the Sorbonne University in Paris, two creators of the “Je Suis Charlie” Facebook page, an American journalist living in Paris who covered the Charlie Hebdo attack and who was present during the November attacks, and a Muslim-American doctor in Phoenix who founded the American Islamic Forum for Democracy. The ideas surrounding free speech, the value of art such as that found within the pages of Charlie Hebdo, the media’s treatment of religion, traditional democratic freedoms and ties to social media revolutions are all components of this research thesis.
Down syndrome (DS) is a common genetic developmental disorder characterized by the trisomy of chromosome 21 (Hsa21). All individuals with DS have some kind of intellectual disability, associated with dysfunction in cognition-related structures, including the frontal cortex. Studies have examined developmental changes in the frontal cortex during prenatal stages in DS, however little is known about cortical lamination and neuronal differentiation in postnatal periods in this neurodevelopmental disorder. Therefore, we examined the quantitative and qualitative distribution of neuronal profiles containing the neuronal migration protein doublecortin (DCX), the non-phosphorylated high-molecular-weight neurofilament SMI-32, the calcium-binding proteins calbindin D-28K (Calb), calretinin (Calr), and parvalbumin (Parv), as well as human β-amyloid and APP (6E10), Aβ1-42, and phospho-tau (CP-13) in the supragranular (SG, II/III) and infragranular (IG, V/VI) layers in the DS postnatal frontal cortex compared to neurotypically developing (NTD) controls from ages 28 weeks to 196.4 weeks using immunohistochemistry. Furthermore, cortical lamination was evaluated using thionin, a Nissl stain. We found DCX-immunoreactive (-ir) cells in both the SG and IG layers in younger cases, but not in the oldest cases in both groups. Strong expression of SMI-32 immunoreactivity was observed in pyramidal cells in layers III and V in the oldest cases in both groups, however SMI-32-ir cells appeared much earlier in NTD compared to DS. We found small and fusiform Calb-ir cells in the younger cases (28 to 44 weeks), while in the oldest cases, Calb immunoreactivity was also found in pyramidal cells. Calr-ir cells appeared earlier in DS at 32 weeks compared to NTD at 44 weeks, however both groups showed large bipolar fusiform-shaped Calr-ir cells in the oldest cases. Diffuse APP/Aβ-ir plaque-like accumulations were found in the frontal cortex grey and white matter at all ages, but no Aβ1-42 immunoreactivity was detected in any case. Furthermore, neuropil (but not cellular) granular CP-13 immunostaining was seen in layer I only at 41 weeks NTD and 33 weeks DS. Cell counts show a significantly higher cell number in SG compared to IG for all the neuronal markers in both groups, except in Calb and SMI-32. In NTD, age and brain weight showed the strongest correlations with all cellular counts, except in thionin where DS had a stronger negative correlation with age and brain weight compared to NTD. In addition, height and body weight showed a strong negative correlation in NTD with the migration and neurogenesis marker DCX. These findings suggest that trisomy 21 affects the postnatal frontal cortex lamination, neuronal migration<br/>eurogenesis, and differentiation of projection pyramidal cells and interneurons, which contribute to the disruption of the local and projection inhibitory and excitatory circuitries that may underlie the cognitive disabilities in DS.
Social media today is a major source of not only communication, but also news and entertainment. This year, people everywhere have had to embrace virtual environments as their main sources of communication. For students, especially, the move to virtual schoolwork in 2020 has increased the amount of time spent on technology. This observational study examined, through an anonymous online survey, how college students spend their time on social media and how it affects their mental health. The 25-question survey was open to current ASU students as of 2021, and 2020 ASU graduates. Respondents’ results concluded that while students actively use social media for communication and entertainment, it can present a burden on their mental health and their productivity.
