Managing code inspection information

Inspection data is difficult to gather and interpret. At AT&T Bell Laboratories, the authors have defined nine key metrics that software project managers can use to plan, monitor, and improve inspections. Graphs of these metrics expose problems early and can help managers evaluate the inspection process itself. The nine metrics are: total noncomment lines of source code inspected in thousands (KLOC); average lines of code inspected; average preparation rate; average inspection rate; average effort per KLOC; average effort per fault detected; average faults detected per KLOC; percentage of reinspections; defect-removal efficiency     

Effect of Different Binders on Release Characteristics of Theophylline from Compressed Microspheres

Microspheres with 60% w/w drug loading were prepared by the solvent-evaporation method using cellulose acetate butyrate as the encapsulating polymer and micronized anhydrous theophylline as the core material. Four different binders - microcrystalline cellulose, glyceryl palmito-stearate, glyceryl stearate and glyceryl behenate were used to compress three different particle sizes of microspheres. Comparison of the in vitro drug dissolution profiles revealed that drug release was fastest from all the microspheres compressed with microcrystalline cellulose as the binder followed by those compressed with glyceryl palmitostearate, glyceryl stearate and glyceryl behenate.     

Introducing survival analysis to organizational researchers: A selected application to turnover research.

Survival analysis, a powerful set of statistical techniques, is introduced. These methods can be useful for turnover research and other behavioral studies with a binary dependent variable and multiple independent variables, any or all of which may be measured over time. Because survival analysis explicitly incorporates time as a variable of interest, it is more flexible and better able to extract and use information from longitudinal studies than methods more commonly used in applied psychology. In this article, we present survival analysis in an intuitive and applications-oriented manner. An application to turnover research is presented for purposes of illustration. With survival analysis, turnover may be viewed as a process whose intensity (rate) is allowed to vary over time rather than remain fixed.

The Response of Hardwood Flakes and Flakeboard to High Temperature Drying

This study assesses the effect of high temperature drying on chemical and mechanical properties of flakes and correlates changes in flake quality with board properties. The high temperature drying of flakes was found to have a significant effect on the internal bond (IB) of the resulting panels. The highest IB values were observed in boards produced from flakes dried at 150°C. Boards produced from flakes dried at 20°C and 350°C exhibited consistently lower values for IB. Opposite trends were noted for total acid content of flake. Multiple regression and correlation analysis revealed a strong relationship between IB, total acid content, and dryer temperature. A significant species effect was also present. Increased levels of flake total acids. acid buffering capacity, and the ratio of acid to base buffering capacities resulted in decreased board property values. Flake bending tests indicated that, in general, the strength and stiffness of the flakes were adversely affected by high temperature drying. This effect did not manifest itself, however, in the resulting panels. Possible reasons for this phenomenon are discussed.     

Escape conditioning in wild and domestic Norway rats.

Tested 16 female wild (lab-reared) and 16 female domestic Norway rats for acquisition of a conditioned escape response. To escape from an aversive stimulus (air blasts) Ss were required to open 1 of 8 doors (simulated burrow entrances) on the presence of a visual cue. Stocks did not differ in the rate of conditioning. Wild Ss exhibited significantly shorter latencies for ambulation and escape than domestic Ss. Removal and reinstatement of the visual cue following acquisition confirmed that the Ss used the cue for orientation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Transient Response of Multiconductor Transmission Lines Excited by a Nonuniform Electromagnetic Field

The time-domain transmission-line equations for uniform multiconductor transmission lines in a conductive, homogeneous medium excited by a transient, nonuniform electromagnetic (EM) field, are derived from Maxwell's equations. Depending on how the line voltage is defined, two formulations are possible. One of these formulations is considerably more convenient to apply than the other. The assumptions made in the derivation of the transmission-line equations and the boundary conditions at the terminations are discussed. For numerical calculations, the transmission -line equations are represented by finite-difference techniques, and numerical examples are included.
