Individual differences in beliefs about groups.

The current research examined individual differences in peoples' positive versus negative beliefs about groups. Three studies were conducted to develop and validate a 16-item Beliefs About Groups (BAG) scale. Factor analyses in Studies 1 and 2 identified and replicated a 4-factor solution, with factors reflecting preferences for group versus individual work, positive group performance beliefs, negative group performance beliefs, and beliefs that others will work hard on group tasks. Study 2 also provided evidence for convergent and divergent validity, and explored relationships between the Big Five personality dimensions and group beliefs. Study 3 provided evidence for test–retest reliability. Across these 3 studies, the BAG scale had total score alphas ranging from .83 to .88. Implications of beliefs about groups for member motivation and group performance, as well as for future research and practice, are highlighted.

Scaling merged single-device-well MOSFETs for very large scale integration

Single-Device-Well (SDW) MOSFETs are high density MOSFET structures based on merging two MOSFET devices; a surface channel device and a buried channel device sharing the same device well and the same gate. SDWs offer a potential device area saving of 50%. The merits of the merged SDW MOSFETs are further enhanced in a scaled down MOSFET VLSI technology. This is the subject of this paper.

Poly I2L with deposited polysilicon collector

A new high speed high density poly I²L structure with deposited polysilicon collector is analyzed and modeled. The switching speed of the proposed poly I²L structure is 4 times higher than that of the conventional structures and the packing density is improved by a factor of 2.The proposed poly I²L structure is gnvestigated using a developed computer simulation model. Parameters sensitivity analysis of the structure is given. The minimum gate delay decreases as the intrinsic base sheet resistivity is increased and as the thin epitaxial layer under the base is decreased. Down scaling effects are discussed. It is shown that a lateral shift of PDP curves along the current axis is proportional to the change in the device area and the IR drop in npn base is proportional to the scaling factor.A structure with technology linewidth L = 2.5 μm exhibits minimum gate delay of 0.6 ns at 150 μA for fan-out F = 3, and a power-delay product of 30 fJ at low current levels. Simulation results are compared with experimental measurements performed on a given poly I²L structure and good agreement has been observed.     

Spectrophotometric and atomic absorption spectrometric determination of certain cephalosporins

Two sensitive spectrophotometric and atomic absorption spectrometric procedures are developed for the determination of certain cephalosporins (cefotaxime sodium and cefuroxime sodium). The spectrophotometric methods are based on the charge-transfer complex formation between these drugs as n-donors and 7,7,8,8-tetracyanoquinodimethane (TCNQ) or p-chloranilic acid (p-CA) as pi-acceptors to give highly coloured complex species. The coloured products are measured spectrophotometrically at 838 and 529 nm for TCNQ and p-CA, respectively. Beer's law is obeyed in a concentration range of 7.6-15.2 and 7.1-20.0 microg x ml(-1) with TCNQ, 95.0-427.5 and 89.0-400.5 microg x ml-1 with p-CA for cefotaxime sodium and cefuroxime sodium, respectively. The atomic absorption spectrometric methods are based on the reaction of the above cited drugs after their alkali-hydrolysis with silver nitrate or lead acetate in neutral aqueous medium. The formed precipitates are quantitatively determined directly or indirectly through the silver or lead content of the precipitate formed or the residual unreacted metal in the filtrate by atomic absorption spectroscopy. The optimum conditions for hydrolysis and precipitation have been carefully studied. Beer's law is obeyed in a concentration range of 1.9-11.4 and 1.78-8.90 microg x ml(-1) with Ag(I), 14.2-57.0 and 13.3-53.4 microg x ml-1 with Pb(II) for cefotaxime sodium and cefuroxime sodium, respectively (for both direct and indirect procedures). The spectrophotometric and the atomic absorption spectrometric procedures hold well their accuracy and precision when applied to the analysis of cefotaxime sodium and cefuroxime sodium dosage forms.
