Measurement and modelling the sensitivity of tetrapolar transfer impedance measurements.

Finite element method (FEM) modelling of a small disk in a homogeneous saline medium showed that the sensitivity distribution for tetrapolar transfer impedance measurements was dependant on the ratio, σdisk/σsaline, and not absolute conductivity values. In addition, the amplitude of the negative sensitivity regions between the drive and receive electrodes decreased non-linearly with σdisk/σsaline for σdisk/σsaline < 1, eventually becoming zero. This non-linear behaviour determined the limit of the assumption of a small change in conductivity in Geselowitz's lead theorem with 0.

A survey of the teaching and assessment of undergraduate psychiatry in the medical schools of the United Kingdom and Ireland.

Background: Individual medical schools currently decide on the content and delivery of their undergraduate psychiatry curriculum, so there is probably significant variation in the students' experience of the speciality during the medical course and in the extent to which they develop the appropriate skills and knowledge base.

Aim: To ascertain how the teaching of undergraduate psychiatry differs across UK and Irish medical schools.

Methods: The educational lead for psychiatry at each medical school in the United Kingdom and Ireland completed a questionnaire providing factual information on the teaching structure, contents and assessment methods in their current psychiatry curriculum.

Service user perspectives about their roles in undergraduate medical training about mental health.

Background: Current policy states that 'service users and carers should be involved in planning, providing and evaluating training for all health care professionals. We wished to explore service users' views regarding undergraduate psychiatry.

Aims: We aimed to explore user perspectives on the specific role of service users in the delivery of teaching psychiatry.

Predictors of online information seeking by international students when disaster strikes their countries.

This study explores factors influencing international students' likelihood of using the Internet to seek disaster-related information should a disaster affect their countries. A cross-sectional survey was conducted in two universities in America between August 1 and September 30, 2005. Two hundred twenty-nine (n = 229) students completed the self-administered questionnaires.

Enforcement of tobacco purchase, use, and possession laws in four Kentucky communities.

This case study examined the implementation and enforcement of the purchase, use, and possession (PUP) laws for tobacco in four Kentucky communities. Purposive and snowball sampling were used to identify 44 adult key informants. Qualitative, semistructured phone interviews assessed knowledge about PUP laws, enforcement, effects of the laws on teen tobacco use, and perceptions about the laws.
