Fluorescence sensor array for metal ion detection based on various coordination chemistries: general performance and potential application.

Abstract: A sensor array containing 9 cross-reactive sensing fluorescent elements with different affinity and selectivity to 10 metal cations (Ca2+, Mg2+, Cd2+, Hg2+, Co2+, Zn2+, Cu2+, Ni2+, Al3+, Ga3+) is described. The discriminatory capacity of the array was tested at different ranges of pH and at different cation concentrations using linear discriminant analysis (LDA). Qualitative identification of cations can be determined with over 96% of accuracy in a concentration range covering 3 orders of a magnitude (5−5000 μM). Quantitative analysis can be achieved with over 90% accuracy in the concentration range between 10 and 5000 μM. The array performance was also tested in identification of nine different mineral water brands utilizing their various electrolyte compositions and their Ca2+, Mg2+, and Zn2+ levels. LDA cross-validation routine shows 100% correct classification for all trials. Preliminary results suggest that similar arrays could be used in testing of the consistency of the purification and manufacturi...

The differential effects of interpersonal conflict from customers and coworkers: trait anger as a moderator.

Abstract: Interpersonal conflict (IC) at work is a frequently experienced type of workplace mistreatment that has been linked to a host of negative workplace outcomes. Previous research has shown that IC can have differential effects based on source, but this has not yet been investigated in terms of customer IC versus coworker IC. To remedy this oversight in the literature, we used a multimethod, multitime point design to compare IC from customers and coworkers experienced by 75 call center employees. Primarily, we investigated burnout, physical health symptoms, and task performance. Results indicated that customer IC was more strongly related to both personal and organizational outcomes. Additionally, trait anger was investigated as a moderator of these relationships, and the results indicated that people who are easy to anger may be more likely to experience negative effects as a result of customer IC. Implications of these findings, limitations, and areas for future research are discussed.

Oxytocin effects on emotional processes: separation distress, social bonding, and relationships to psychiatric disorders.

Abstract: Centrally administered oxytocin exerts powerful effects on a large variety of behavioral and physiological processes.'t2 As documented in many chapters of this volume, a substantial role for oxytocin has been established in the control of sexual and maternal behaviors in all mammalian species that have been studied. Homologous patterns of behavior have been observed following central administration of the evolutionary precursor, vasotocin, into avian and reptilian species, suggesting a remarkable conservation of sociosexual functions for this family of posterior pituitary nonapeptides.) The behavioral effects of oxytocin offer a prime example of a general principle which seems to be emerging from neuropeptide research-that there is a functional harmony between the peripheral and central effects of neuropeptides. One working premise of our research is that this principle holds not only for the physiological and behavioral effects of these hormones, but that it also extends to the emotional/psychological effects of these peptides within the brain. Indeed, neuropeptides may serve as key neuromodulators within the genetically provided emotional operating systems of the brain that coordinate behavioral, physiological, and psychological responses to major life-challenging circum~tances.~J In other words, many peptide systems may serve command functions in the brain that help synchronize a variety of bodily and brain systems to unconditionally promote coherent organismic response to primal survival needs. Other examples of this general principle are the ability of angiotensin to conserve water in the periphery and instigate thirst centrally,6 the ability of insulin to conserve fuel peripherally and to facilitate satiety centrally,' the ability of MSH to promote pigmentary camouflage peripherally and hiding behaviors centrally,8 the ability of CRF to promote stress responses peripherally and anxiety ~entrally,~ and the ability of LH-RH to promote gonadal readiness peripherally and sexual urgency centrally.'O One of the most striking examples of this principle is the ability of oxytocin to mediate maternal intent, sexual readiness, and perhaps neuropsychic emotional patterns that go along with these behavioral tendencies. Although neurodynamic emotional processes are difficult to measure empirically, some indication of the status of such putative brain systems can be obtained through the analysis of the unconditional emotive behavior patterns in animal^.^.^ A straightforward emotional prediction is that brain oxytocin may evoke warm positive feelings of social strength and comfort when aroused by peripheral stimuli. For instance, as mother and infant share in the nursing experience, brain oxytocin

Naphthalimide Phosphorescence Finally Exposed in a Platinum(II) Diimine Complex

Abstract: Room temperature (RT) phosphorescence is observed from a naphthalimide species for the first time in the square-planar chromophore Pt(dbbpy)(C≡C—NI)2, where NI = N-butyl-4-ethynylnaphthalimide and dbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine. The combination of static and time-resolved absorption and photoluminescence data is uniformly consistent with triplet-state photophysics localized on an appended C≡C—NI unit following excitation into the low-energy absorption bands. This molecule features rather impressive long-lifetime, high-quantum-efficiency NI-based RT phosphorescence (τ = 124 μs; Φ = 0.215) centered at 621 nm, exemplifying how the platinum acetylide linkage strongly promotes intersystem crossing in the NI subunit, representative of a class of molecules whose excited states are typically dominated by singlet fluorescence.
