Quantitative recording of electron patterns and their rapid conversion into digital information is an outstanding goal which the photoplate fails to solve satisfactorily. For a long time, LLL-TV cameras have been used for EM adjustment but due to their inferior pixel number they were never a real alternative to the photoplate. This situation has changed with the availability of scientific grade slow-scan charged coupled devices (CCD) with pixel numbers exceeding 106, photometric accuracy and, by Peltier cooling, both excellent storage and noise figures previously inaccessible in image detection technology. Again the electron image is converted into a photon image fed to the CCD by some light optical transfer link. Subsequently, some technical solutions are discussed using the detection quantum efficiency (DQE), resolution, pixel number and exposure range as figures of merit.A key quantity is the number of electron-hole pairs released in the CCD sensor by a single primary electron (PE) which can be estimated from the energy deposit ΔE in the scintillator,

In recent years, several studies have addressed the issue of positive self-presentation bias in assessing parents involved in postdivorce child custody litigations. The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is widely used in forensic assessments and is able to evaluate positive self-presentation through its Superlative Self-Presentation S scale. We investigated the existence of a gender effect on positive self-presentation bias in an Italian sample of parents involved in court evaluation. Participants were 391 divorced parents who completed the full 567-item Minnesota Multiphasic Personality Inventory-2 during child custody evaluations ordered by several Italian courts between 2006 and 2010. Our analysis considered the S scale along with the basic clinical scales. North-American studies had shown no gender differences in child custody litigations. Differently, our results showed a significantly higher tendency toward “faking-good” profiles on the MMPI-2 among Italian women as compared to men and as compared to the normative Italian female population. Cultural and social factors could account for these differences.

Child sexual abuse is a social and health issue that affects citizens across the globe. It has a number of physical, psychological and emotional consequences. Children are reluctant to talk about their involvement in sexual abuse owing to various reasons. Therefore, forensic interviewers need to understand the process of disclosure when conducting forensic assessments. They also need to be watchful of various dynamics that are likely to have an impact on the disclosure rate. The aim of this study was to describe the dynamics during forensic assessments in the context of the black South African child when disclosing child sexual abuse. A descriptive design using stratified random, purposive and convenient sampling techniques to select the participants was employed, resulting in 14 participants (13 were females and only one was male). The data were collected by means of semi-structured in-depth interviews and were thematically analysed using the Nvivo program. The findings reveal that personal characteristics of the child and the interviewer, their communication abilities, blind assessments and informed allegation interviews have an impact on forensic assessments of black South African children. It is concluded that the dynamics of disclosing child sexual abuse during forensic assessments in terms of the variables of the study are not unique, except in terms of sociocultural value systems, beliefs and customs. As a result, it is recommended that the forensic interviewers come to the developmental level of the child, speak his/her language or use translators for him/her to understand, and to follow blind assessments interviews as opposed to informed allegation interviews. However, informed allegations interviews are recommended when assessing very young children.

Responsive architecture, a design field that has arisen in recent decades at the intersection of architecture and computer science, invokes a material response to digital information and implies the capacity of the building to respond dynamically to changing stimuli. The question I will address in the paper is whether it is possible for the responsive components of architecture to become a poetically expressive part of the building, and if so why this result has so rarely been achieved in contemporary and recent built work. The history of attitudes to- ward obsolescence in buildings is investigated as one explanation for the rarity of examples like the one considered here that successfully overcomes the rapid obsolescence of responsive components and makes these elements an integral part of the work of architecture. In conclusion I identify strategies for the design of responsive components as poetically expressive elements of architecture.
