Summer nighttime abundance and localized distribution of fishes in a tidal cove were studied by beach seining for comparison with a previous daytime study. American eels were relatively abundant at night and absent during the day. Alewife, blueback herring, and Atlantic silver-side were more abundant in the cove at night. Although mummichog numbers were greatly reduced at night, they remained an important constituent of the night fauna. Lesser components of the night fauna included Atlantic herring, Atlantic tomcod, smooth flounder, winter flounder, and rainbow smelt.

The effects of exchange rate risk have interested researchers, since the collapse of fixed exchange rates. Little consensus exists, however, regarding its effect on exports. Previous studies implicitly assume symmetry. This paper tests the hypothesis of asymmetric effects of exchange rate risk with a dynamic conditional correlation bivariate GARCH(1,1)-M model. The asymmetry means that exchange rate risk (volatility) affects exports differently during appreciations and depreciations of the exchange rate. The data include bilateral exports from eight Asian countries to the US. The empirical results show that real exchange rate risk significantly affects exports for all countries, negative or positive, in periods of depreciation or appreciation. For five of the eight countries, the effects of exchange risk are asymmetric. Thus, policy makers can consider the stability of the exchange rate in addition to its depreciation as a method of stimulating export growth.

If elementary Quantum Chemistry stops at diatomic molecules, some students may be left with false impressions concerning how one builds polyatomic molecule's LCAO-MOs. This reading discusses building such molecular orbitals from atomic orbitals centered at different spatial coordinates.

There is increasing evidence that childhood victimization and attachment disruptions impact a child’s development. In this study, children and adolescents from an outpatient psychiatric clinic were assessed, measuring history of trauma, history of out-of-home placement, initial diagnoses, and CBCL internalizing and externalizing problem scores. Multiple regression analyses showed that both violent abuse trauma (physical/sexual abuse) and victim trauma (physical abuse/sexual abuse/witnessing domestic violence/witnessing community violence) are prevalent among patients with externalizing severity problems; concluding that diagnosis alone may not account for a history of victimization, but externalizing problem severity does. Overall, the study is consistent with past literature that it is important to acknowledge a child’s history of maltreatment and out-of-home placement when understanding their psychiatric development and diagnosis.
