Snapchat and Sexting: a Snapshot of Baring Your Bare Essentials

This comment explores sexting between minors and its inseparable link to Snapchat. Part II provides background information on the practice and prevalence of sexting. Part III explains the Snapchat application and its various uses. Part IV discusses the implications of sexting, legal and otherwise. Part V examines how Snapchat directly conflicts with current law.13 Lastly, Part VI proposes possible solutions

Repealing Section 1031: The Economic Impact

The purpose of this paper was to assess the impact of a modification and or repeal of section 1031 in the U.S. Tax code. Specifically, this paper focused on a revenue-neutral repeal effect in which the additional proceeds from the repeal of section 1031 would go towards decreasing the corporate income tax rate. Overall, the treasury would remain neutral. The implications of this potential repeal were wide. The macroeconomic effect on the economy appeared to be negative, all other things being equal. GDP is predicted to fall by .11% each year. Additionally, Investment will be negatively affected with the decreased liquidity of exchangeable assets due to longer holding periods of these assets. Investors should expect to hold these assets longer to decrease their effective tax rate over the life of the investment. Investment is predicted to decline by $7 billion. Real Estate will be the industry that will ultimately be affected the most by a repeal situation as the real estate sector uses like-kind exchanges more frequently than in any other industry. Overall, we can expect to see small declines in macroeconomic factors due to the repeal of this provision that has been benefiting investors for decades

Effect of Polar Protic and Polar Aprotic Solvents on Negative-Ion Electrospray Ionization and Chromatographic Separation of Small Acidic Molecules

A comprehensive study investigated the effect of polar protic (methanol and water) and polar aprotic (acetonitrile and acetone) solvents on the chromatographic separation and negative-ion electrospray (ESI) response of 49 diverse small, acidic molecules. Flow injection experiments on a triple quadrupole were used to measure the response in neat solvents after optimization of source conditions and implementation of a rigorous quality control program (the later ensured that changes in analyte response were due to the analyte/solvent measured and not changes in instrument performance over time). In all solvents, compounds with electron-withdrawing groups and extended conjugation ionized best due to resonance and inductive effects. Ionization was greatest in methanol or water for all compounds that elicited a response, thus revealing that enhanced sensitivity and lower limits of detection are achieved with polar protic solvents. Response in acetone was equal to or slightly lower than response in acetonitrile in flow injection experiments; however, the water/acetonitrile and water/acetone mobile phases produced the better chromatographic separation. Water/methanol produced slightly less satisfactory separation but the greatest overall response. This increase in response was attributed to the protic nature of methanol and the elution of compounds in a higher organic mobile phase composition (retention times were ∼30% later in methanol). This work is intended to facilitate rational liquid chromatography/mass spectrometry method development for small molecule applications, including metabolomics

Fourier Transform-Ion Mobility-Orbitrap Mass Spectrometer: A Next-Generation Instrument for Native Mass Spectrometry

A new instrument configuration for native ion mobility-mass spectrometry (IM-MS) is described. Macromolecule ions are generated by using a static ESI source coupled to an RF ion funnel, and these ions are then mobility and mass analyzed using a periodic focusing drift tube IM analyzer and an Orbitrap mass spectrometer. The instrument design retains the capabilities for first-principles determination of rotationally averaged ion-neutral collision cross sections and high-resolution measurements in both mobility and mass analysis modes for intact protein complexes. Operation in the IM mode utilizes FT-IMS modes (originally described by Knorr ( Knorr, F. J. Anal. Chem. 1985, 57­(2), 402−406 )), which provides a means to overcome the inherent duty cycle mismatch for drift tube (DT)-IM and Orbitrap mass analysis. The performance of the native ESI-FT-DT-IM-Orbitrap MS instrument was evaluated using the protein complexes Gln K (MW 44 kDa) and streptavidin (MW 53 kDa) bound to small molecules (ADP and biotin, respectively) and transthyretin (MW 56 kDa) bound to thyroxine and zinc
