We present a formalism for the analysis of sensitivity of nuclear magnetic resonance pulse sequences to variations of pulse sequence parameters, such as radiofrequency pulses, gradient pulses or evolution delays. The formalism enables the calculation of compact, analytic expressions for the derivatives of the density matrix and the observed signal with respect to the parameters varied. The analysis is based on two constructs computed in the course of modified density-matrix simulations: the error interrogation operators and error commutators. The approach presented is consequently named the Error Commutator Formalism (ECF). It is used to evaluate the sensitivity of the density matrix to parameter variation based on the simulations carried out for the ideal parameters, obviating the need for finite-difference calculations of signal errors. The ECF analysis therefore carries a computational cost comparable to a single density-matrix or product-operator simulation. Its application is illustrated using a number of examples from basic NMR spectroscopy. We show that the strength of the ECF is its ability to provide analytic insights into the propagation of errors through pulse sequences and the behaviour of signal errors under phase cycling. Furthermore, the approach is algorithmic and easily amenable to implementation in the form of a programming code. It is envisaged that it could be incorporated into standard NMR product-operator simulation packages.

This article presents findings from a longitudinal study. The research aimed to explore the effectiveness of a treatment program for offenders which lasted for three years. The research design was structured around the program with interviews and psychometric testing undertaken at key points in time with the same group of respondents. View all notes that sought to evaluate a treatment program for child sexual abusers. A triangulated methodological approach was adopted drawing upon quantitative and qualitative methodological techniques. The focus here is upon one element of this research. 2 2The quantitative element of this research will be published shortly but is referred to in the following reports Davidson 2000, 2003 [research funded by the National Probation Service]. Psychometric testing was undertaken over a four-year period with the men attending the treatment program to explore shifts in the extent of denial, blame attribution, and victim empathy over time. Offender cognitive distortions, general health, and self-esteem were also explored via psychometric testing. An interview-administered survey was undertaken with all sex offenders registered with the Probation Service (those on probation and in custody) in order to gather demographic data, and 117 of 150 offenders responded. View all notes Ninety-one in-depth interviews were conducted over a four-year period with a small, nonrandom sample of twenty-one male offenders who had been convicted of sexual offenses against children. All of the men were subject to probation orders with a psychiatric condition (Criminal Justice Act, 1991). One of the aims of this element of the research was to explore the extent to which evidence of denial could be found in offenders’ accounts of offense circumstance and also to explore the extent to which offenders minimized the nature and extent of abuse perpetrated. Offenders’ accounts of offense circumstances were compared to victim statements, and stark differences emerge. These findings have considerable implications for treatment practice with sex offenders, where victims’ perceptions could be used to directly confront offender denial and minimization.

Purpose – In the context of global knowledge economy, knowledge-based urban development (KBUD) is seen as an effective development strategy for city-regions to survive, flourish and become highly competitive urban agglomerations – i.e., a knowledge city-region. This paper aims to evaluate the KBUD dynamics, capacity and potentials of a rapidly emerging knowledge city-region of Finland – Tampere region. Design/methodology/approach – The paper undertakes a review of the literature on regional development in the knowledge economy era. It adopts a qualitative analysis technique to scrutinize the dynamics, capacity and potentials of Tampere region. The semi-structured interview process starts with the pre-determined key actors of the city-region with an aim of determining the other key players. Next, with the participation of all key players to the interviews, the research reveals the principal issues, assets and mechanisms that relate to KBUD, and portrays the strengths, weaknesses, opportunities and threats of the city-region. A critical analysis of the findings along with the previous studies is undertaken to provide a clear picture of the dynamics, capacity and potentials of the emerging knowledge city-region. Originality/value – This paper reports the findings of a pioneering study focusing on the investigation of the KBUD dynamics, capacity and potentials of Tampere region. The paper critically evaluates the city-region from the knowledge perspective with the lens of KBUD, and the lessons learned and the methodological approach of the paper shed light to other city-regions seeking such development. Practical implications – The paper discusses the findings of a study from Tampere region that critically scrutinizes the KBUD experience of the city-region. The research provides an invaluable opportunity to inform the regional decision-, policy- and plan-making mechanisms by determining key issues, actors, assets, processes and potential development directions for the KBUD of Tampere region.

Purpose: The aim of this study was to examine whether older people are prepared to engage in appropriate falls prevention strategies after discharge from hospital. Design and Methods We used a semi-structured interview to survey older patients about to be discharged from hospital and examined their knowledge regarding falls prevention strategies to utilize in the post-discharge period. The study was part of a prospective cohort study, nested within a larger, randomized controlled trial. Participants (n = 333) were asked to suggest strategies to reduce their falls risk at home after discharge, and their responses were compared with current reported research evidence for falls prevention interventions. Results Participants’ strategies (n = 629) were classified into 7 categories: behavioral, support while mobilizing, approach to movement, physical environment, visual, medical, and activities or exercise. Although exercise has been identified as an effective falls risk reduction strategy, only 2.9% of participants suggested engaging in exercises. Falls prevention was most often conceptualized by participants as requiring 1 (35.4%) or 2 (40.8%) strategies for avoiding an accidental event, rather than engaging in sustained multiple risk reduction behaviors. Implications Results demonstrate that older patients have low levels of knowledge about appropriate falls prevention strategies that could be used after discharge in spite of their increased falls risk during this period. Findings suggest that health care workers should design and deliver falls prevention education programs specifically targeted to older people who are to be discharged from hospital.

Nurse education in Viet Nam is undergoing substantial reform. In order to facilitate the change, in 2007 the Viet Nam Nurses Association formed a collaborative partnership with the School of Nursing and Midwifery at an Australia university. This collaboration gave rise to the Viet Nam Nursing Capacity Building Project under the leadership of Professor Genevieve Gray, funded by the Atlantic Philanthropies. The new four year competency based nursing curriculum frame is expected to be implemented in September 2011 following approval by the Viet Nam Ministry of Education. The focus of this paper is the Teaching Fellowships Program, an initiative of the Viet Nam Nursing Capacity Building Project, developed to help meet the challenges associated with leading and dealing with the curriculum change. The paper explores the development of the program and justifies an action research approach, illuminates key issues, and briefly refers to changes to the next fellowship program.
