Rationale: NBS19 carbonate, a primary reference material (RM) for the Vienna Pee Dee Belemnite (VPDB) scale realisation introduced in 1987, was exhausted in 2009, and no primary RM was available for several years. This study describes the preparation and characterisation of a new RM, IAEA-603 (Ca-carbonate, calcite of marble origin), which shall serve as a new primary RM (replacement for NBS19) or primary calibrator aimed at the highest realisation of the VPDB scale for δ C and δ O values, including the VPDB-CO δ O scale.
Methods: IAEA-603 preparation and characterisation (value transfer) against NBS19 were performed by addressing the major modern technical requirements for the production and characterisation of RMs (ISO Guide 35).

Background: Geriatric patients are increasingly dominating the daily routine in German emergency departments (ED). With their typical characteristics multimorbidity, polypharmacy, vulnerability, frailty and cognitive impairment, especially delirium, they are a special challenge for the processes in the ED. Though some emergency physician might consider "the old patient" as not exciting, there is a broad consensus that pragmatic geriatric screening tools are required.

Annual proficiency tests (PTs) are organized for the network laboratories using sets of different samples typically encountered in environmental and food monitoring laboratories. The PT system is designed to respond to the needs of the network for rapid response and reliable measurement results, and to metrological principles and international standards and guides.

SGD intercomparison exercises were carried out to validate the various approaches used to measure SGD including radium and radon measurements, seepage rate measurements using manual and automated meters, sediment bulk conductivity and salinity surveys. SGD measurements using benthic chambers placed on the floor of the Flic-en-Flac Lagoon showed discharge rates up to 500 cm/day.

In North America, reductions in population smoking levels are stabilising and, in recent years, those involved in tobacco control programming have turned their attention to particular segments of society that are at greatest risk for tobacco use. One such group is people with mental illness.

As effective communication is an essential professional competency that is conceptualized and developed during undergraduate education, the purpose of this study was to investigate and reinforce the role of communication in the nursing undergraduate curriculum. Analysis of faculty and student focus group discussions revealed the benefit of purposefully structuring and explicitly articulating communication education throughout the undergraduate curriculum for increased accessibility and visibility of communication education, expanded ranges of available teaching and learning methods and resources, and strengthened ability to address undermining mixed communication messages. These findings have implications for how to specifically include communication education in a learning-centered undergraduate curriculum.

The study also aimed to determine whether the providers' attitudes, smoking status, and confidence were associated with offering smoking cessation support to clients.
Methods: Self-administered questionnaires were distributed within community-based mental health agencies to those who provide care and support to adults living with severe mental illness.

A complex approach in characterisation of submarine groundwater discharge (SGD) off south-eastern Sicily comprising applications of radioactive and non-radioactive tracers, direct seepage measurements, geophysical surveys and a numerical modelling is presented. SGD fluxes in the Donnalucata boat basin were estimated by direct seepage measurements to be from 4 to 12Ls(-1), which are comparable with the total SGD flux in the basin of 17Ls(-1) obtained from radon measurements. The integrated SGD flux over the Donnalucata coast estimated on the basis of Ra isotopes was around 60m(3)s(-1) per km of the coast.

The authors' clinical trial of a tailored, nurse-administered smoking cessation intervention for surgical patients included a telephone counseling component and provided an opportunity to describe the interaction dynamics of proactive telephone counseling over the course of 4 months. Tape-recorded telephone counseling calls for 56 consecutively enrolled individuals randomized to the intervention group resulted in a data set of 368 calls, which were transcribed and analyzed using constant comparative methods.

The article is a discussion of the concept of countertransference in psychotherapy, specifically as to how it may be applied to understanding clinical teachers' subjective responses to students. The authors present arguments to support the fit between the concept of countertransference and clinical teaching, focusing on the negative effects of a teacher's countertransference in clinical teaching.
