Some Men Just Want To Watch The World Burn: The Role Of Sensation Seeking, Impulsivity, And Empathy In Cyberbullying

This study explored the potential role of sensation seeking, impulsivity, and empathy in cyberbullying behavior directed towards known and unknown persons. Sensation seeking is one’s propensity to desire novel situations and stimuli. Impulsivity is one’s tendency to engage in behavior without regard for potential consequences. Empathy is conceptualized as one’s ability to understand the experiences and emotions of others. Cyberbullying is the act of intentionally aggressing against another individual via some form of technology. University of Mississippi students (N=393) participated in an online survey and completed measures of the aforementioned variables. Cyberbullying behavior was measured in the context of aggressing towards both known and unknown persons. When sensation seeking was examined as a mediator between impulsivity and cyberbullying of known persons, a significant indirect path was found, indicating mediation. A similar trend relationship was observed for cyberbullying of unknown persons. Results and implications of findings are discussed

Report of the 2020-2021 Strategic Engagement Standing Committee

EXECUTIVE SUMMARY For the American Association of Colleges of Pharmacy (AACP), strategic engagement is critical to the success of colleges and schools of pharmacy in expanding pharmacy and public health practice, meeting programmatic needs, and fulfilling institutional missions. The 2020-2021 Strategic Engagement Standing Committee was charged with identifying effective strategies to leverage the temporary expansion of pharmacist practice capabilities granted during the COVID-19 pandemic for sustained practice. The group was also tasked with looking at ways to partner with the Association of American Medical Colleges (AAMC), our medicine counterparts to develop a plan for collaborating with them to advance interprofessional practice. In this unique year, all standing committees were charged with reading all the reports last year to put President Lin’s charges into perspective with the hopes of carrying over the overall theme and work of the previous years committee. Overall, throughout the COVID-19 pandemic, there have been several expansions on the scope of practice for pharmacists and vary by state. We hope to draw out some of those expansions to see how we can build upon efforts to make those permanent

Characterization of Mycobacterium chelonae-like strains by comparative genomics

Isolates of the Mycobacterium chelonae-M. abscessus complex are subdivided into four clusters (CHI to CHIV) in the INNO-LiPA (R) Mycobacterium spp DNA strip assay. A considerable phenotypic variability was observed among isolates of the CHII cluster. In this study, we examined the diversity of 26 CHII cluster isolates by phenotypic analysis, drug susceptibility testing, whole genome sequencing and single-gene analysis. Pairwise genome comparisons were performed using several approaches, including average nucleotide identity (ANI) and genome-to-genome distance (GGD) among others. Based on ANI and GGD the isolates were identified as M. chelonae (14 isolates), M. franklinii (2 isolates) and M. salmoniphium (1 isolate). The remaining 9 isolates were subdivided into three novel putative genomospecies. Phenotypic analyses including drug susceptibility testing, as well as whole genome comparison by TETRA and delta differences, were not helpful in separating the groups revealed by ANI and GGD. The analysis of standard four conserved genomic regions showed that rpoB alone and the concatenated sequences clearly distinguished the taxonomic groups delimited by whole genome analyses. In conclusion, the CHII INNO-LiPa is not a homogeneous cluster; on the contrary, it is composed of closely related different species belonging to the M. chelonae-M. abscessus complex and also several unidentified isolates. The detection of these isolates, putatively novel species, indicates a wider inner variability than the presently known in this complex

The Spitzer c2d survey of large, nearby, interstellar clouds. I. Chamaeleon II observed with MIPS

We present maps of over 1.5 deg2 in Chamaeleon (Cha) II at 24, 70, and 160 μm observed with the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS) and a 1.2 deg2 millimeter map from SIMBA on the Swedish-ESO Submillimetre Telescope (SEST). The c2d Spitzer Legacy Team's data reduction pipeline is described in detail. Over 1500 24 μm sources and 41 70 μm sources were detected by MIPS with fluxes greater than 10 σ. More than 40 potential YSOs are identified with a MIPS and 2MASS color-color diagram and by their spectral indices, including two previously unknown sources with 24 μm excesses. Our new SIMBA millimeter map of Cha II shows that only a small fraction of the gas is in compact structures with high column densities. The extended emission seen by MIPS is compared with previous CO observations. Some selected interesting sources, including two detected at 1 mm, associated with Cha II are discussed in detail, and their SEDs are presented. The classification of these sources using MIPS data is found to be consistent with that of previous studies

Transcription Factors Mat2 and Znf2 Operate Cellular Circuits Orchestrating Opposite- and Same-Sex Mating in Cryptococcus neoformans

Cryptococcus neoformans is a human fungal pathogen that undergoes a dimorphic transition from a unicellular yeast to multicellular hyphae during opposite sex (mating) and unisexual reproduction (same-sex mating). Opposite- and same-sex mating are induced by similar environmental conditions and involve many shared components, including the conserved pheromone sensing Cpk1 MAPK signal transduction cascade that governs the dimorphic switch in C. neoformans. However, the homeodomain cell identity proteins Sxi1α/Sxi2a encoded by the mating type locus that are essential for completion of sexual reproduction following cell–cell fusion during opposite-sex mating are dispensable for same-sex mating. Therefore, identification of downstream targets of the Cpk1 MAPK pathway holds the key to understanding molecular mechanisms governing the two distinct developmental fates. Thus far, homology-based approaches failed to identify downstream transcription factors which may therefore be species-specific. Here, we applied insertional mutagenesis via Agrobacterium-mediated transformation and transcription analysis using whole genome microarrays to identify factors involved in C. neoformans differentiation. Two transcription factors, Mat2 and Znf2, were identified as key regulators of hyphal growth during same- and opposite-sex mating. Mat2 is an HMG domain factor, and Znf2 is a zinc finger protein; neither is encoded by the mating type locus. Genetic, phenotypic, and transcriptional analyses of Mat2 and Znf2 provide evidence that Mat2 is a downstream transcription factor of the Cpk1 MAPK pathway whereas Znf2 functions as a more terminal hyphal morphogenesis determinant. Although the components of the MAPK pathway including Mat2 are not required for virulence in animal models, Znf2, as a hyphal morphology determinant, is a negative regulator of virulence. Further characterization of these elements and their target circuits will reveal genes controlling biological processes central to fungal development and virulence
