To ask, or not to ask, about abuse--New Zealand research.

Comments on the article by K. Becker-Blease and J. Freyd (see record 2006-03947-003), which addressed the ethics of asking and not asking research subjects about abuse. J. Read reviews some clinical research in New Zealand in which there was a low level of inquiry about abuse by mental health staff, and notes that this is consistent with the results of similar studies elsewhere. He agrees with Becker-Blease and Freyd that there are many consequences to researchers and clinicians of not asking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

An analytical and experimental analysis of a very fast thermal transient

According to some international standards, some products, developed for use under heavy thermal conditions, have to be tested by subjecting them for a short time to a particular heating and cooling thermal stress to allow them an acceptable future operative life. It is possible to obtain these fast thermal gradients in confined environments, called climatic chambers where the air is heated by an electrical resistance and is cooled with a finned evaporator which is linked to a vapour compression system subjected to a particular control system of the refrigerating power. In particular, in this paper the air and object tested thermal transients are studied from an analytical and experimental point of view. The study of the mathematical model is realized assuming simplified hypotheses about the air, the object and the air cooled evaporator temperature. The most complex circumstances are related to a very fast temperature decrease because under this working condition the mathematical model is characterized by a nonlinear differential system. The nonlinear term is represented by the refrigerating power that varies in a definite range with the evaporator temperature according to a sinusoid trend. For this power a suitable analytical expression, derived by the control system performance and by the compressor characteristic, has been found. The analytical–experimental comparison during a cooling thermal stress of typical products subjected to international standard tests as the electronic boards, has been carried out showing acceptable results. The model presented is useful to foresee the climatic chamber performances in the presence of a specific refrigerating power trend; this is the start‐point for the design of the vapour compression plant and its control system.

The question of psychologists' maltreatment by state licensing boards: Overcoming denial and seeking remedies.

The state and provincial boards that regulate the practice of psychology may regularly engage in a variety of investigative and enforcement practices that fail to provide due-process protection for accused psychologists. Because psychology regulatory boards operate under administrative law, rather than under civil or criminal law, familiar due-process protections may be considered unnecessary, or they may be perceived to be antithetical to the mandate of these boards to protect the public. Examples of board practices that bypass due-process protection are provided. An agenda is offered to state psychological associations to monitor the actions of their state psychology boards, to independently investigate complaints by members of unfair board practices, to offer support to members facing licensing complaints, and to propose appropriate legislative remedies for unfair board practices in their respective states and provinces.

Dielectric properties of FR-4 laminates as a function of thickness and the electrical frequency of the measurement

The relationship between the dielectric properties (dielectric constant, ε _lam ^′ and loss factor, ε _lam ^″ ) and thickness of FR-4 laminates was investigated. Thickness variations for laminates reinforced by the same style and number of plies of glass cloth were predominantly due to differences in the resin content. At each measurement frequency, values of both ε _lam ^′ and ε _lam ^″ were found to vary in an approximate linear manner with changes in the volume fraction of resin,V _rsn . An empirical equation was derived that gives the dielectric constant of an FR-4 laminate, ε _lam ^′ , as a function of the volume fraction of resin,V _rsn , and the frequency at which the measurement was performed (between 1 kHz and 1 GHz). An alternative expression was also determined that permits the calculation of ε _lam ^′ in the same frequency range from just the dielectric thickness of the laminate, providing the effective thickness of the reinforcement is known. The effective thickness of one style of glass cloth (2116) was experimentally determined to be 1.6 mils/ply. Effective thicknesses of most other common woven glass reinforcements used in FR-4 laminates were calculated and tabulated. The empirical relationships should be a valuable aid to electrical designers and others who need to know the frequency dependence of the dielectric properties of FR-4 laminates having different glass-to-resin ratios.
