The purpose of this paper is to describe how an Academic Health Science Centre, providing pediatric rehabilitation services, research, and education, developed a Centres for Leadership (CfL) initiative to integrate its academic functions and embrace the goal of being a learning organization.

Historical documents, tracked output information, and staff members’ insights were used to describe the ten-year evolution of the initiative, its benefits, and transformational learnings for the organization.

The evolutions concerned development of a series of CfLs, and changes over time in leadership and management structure, as well as in operations and targeted activities. Benefits included enhanced clinician engagement in research, practice-based research, and impacts on clinical practice. Transformational learnings concerned the importance of supporting stakeholder engagement, fostering a spirit of inquiry, and fostering leaderful practice. These learnings contributed to three related emergent outcomes reflecting “way stations” on the journey to enhanced evidence-informed decision making and clinical excellence: enhancements in authentic partnerships, greater innovation capacity, and greater understanding and actualization of leadership values.

Practical information is provided for other organizations interested in understanding how this initiative evolved, its tangible value, and its wider benefits for organizational collaboration, innovation, and leadership values. Challenges encountered and main messages for other organizations are also considered.

A strategy map is used to present the structures, processes, and outcomes arising from the initiative, with the goal of informing the operations of other organizations desiring to be learning organizations.

This paper aims to provide an overview of current and historical arcjet development. The reviewed arcjets are considered with respect to both design and thruster relevant parameters. Correspondingly, the paper enables the identification of adequate design criteria and of the probable thruster parameters.

The approach consists of a database for thruster relevant parameters in conjunction with relevant operational requirements (such as type of propellant) and specific design criteria (such as e.g. propellant injection systems).

The synopsis of both operational parameter and respectively assigned design allows for the derivation of development approaches for arcjets under given high level requirements such as power regime.

The paper is a general review. However, its strength is in the synthesis of the arcjet classification, the functional evidence of design criteria and the application scenario.

Not only basic but also specific design criteria are analyzed and evaluated leading to a recommendation feature of the paper with respect to the overall design of adequate arcjets.

Within the scope of the Clean Space initiative, new applications and scenarios from the operation of arcjets arise enabling EOL phases of spacecraft that fulfill respective levels of debris mitigation and, in addition, the requirements concerning the adequately adapted re-entry of spacecrafts that are at end of life.

The paper is a general review. However, its strength is in the synthesis of the arcjet classification, the functional evidence of design criteria and the application scenario.

Various polyesteramide resins are prepared in which a stoichiometric amount of hydroxy ethyl fatty acid amides (diol) are replaced by the bifunctional nicotinic acid and aisonicotinic acid derivatives of diethanolamine and triethanolamine without affecting the resin constants. The inclusion of nicotinyl and isonicotinyl residues would expect to prevent microbial growth and may also act as corrosion inhibitor.

The training of future mental health professionals offers one avenue of change to improve service user and carer involvement in mental health services. This study looked at experiences of trainees on the University of Surrey's Clinical Psychology Doctorate programme in involving service users and carers on training placements. Twenty trainees completed a self‐report semistructured questionnaire providing qualitative data that were analysed using thematic analysis. A number of benefits of service user and carer involvement in training were identified as well as practical considerations, including factors that might facilitate or limit such involvement on training placements. It is intended that the findings will prove useful to others involved with the training of mental health professionals.

General aviation aircraft has a wide range of applications, and effective cost management is one of the hot spots in the research of general aviation manufacturers. The purpose of this paper is to build a flexible engineering method to predict maintenance cost of general aviation aircraft.

To establish a reasonable general aviation aircraft maintenance cost prediction model, it is necessary to analyze the influencing factors and extract the main components of maintenance cost. The maintenance cost is divided by engineering method, and the estimation model of each component cost is established. Then, the general aviation aircraft maintenance cost model is obtained. The results show that the relative error of this method is between 13% and 20%, which has a good estimation accuracy and can be effectively used to estimate the maintenance cost of general aviation aircraft.

The maintenance cost plays an important role in the life cycle cost of general aviation aircraft. Accurate cost prediction method is of great significance to the optimal design of general aviation aircraft. However, there are few prediction models suitable for maintenance cost, the proposed approach is meaningful and quite desirable.

To some extent, this method overcomes the shortage of the work on maintenance cost prediction for general aviation aircraft. The model established in this paper has certain generality, which can provide some reference for general aviation aircraft design and operation enterprises.

Reports a comprehensive field study of atmospheric ammonia (NH⊂3) concentration which was conducted in Jiddah, Saudi Arabia (one of the fastest growing cities in the world) for the period 1984‐1987. Ammonia trends have been developed for five stations in Jiddah: daily, monthly and annual means, maximum and mean maximum reported. The average NH⊂3 concentration for 1984, 1985, 1986 and 1987 was 0.027 μl/l, 0.023 μl/l, 0.018 μl/l and 0.020 μl/l, respectively. A decrease in NH⊂3 concentration from 1984 to 1987 was observed. The four years′ average concentration was 0.022 μl/l and a maximum of 0.490 μl/l was recorded once at station 104 in 1984. The statistical significance of data and background information for air quality standards for the city are discussed. Analysis of data shows a lower mean than any international air quality standards.

There is an ongoing debate about how specialist psychiatric services for people with learning disabilities and mental health problems should be developed. Nursing personnel are the largest professional group involved with care provision, yet to date there has been little research addressing the knowledge and experiences of learning disability and mental health nurses co‐working with this population. This aim of this study was to explore the perceptions of these nurses, using qualitative methods. The findings are discussed in relation to A Vision for Change (DoHC, 2006) and in comparison with the innovative collaborative working that has occurred with the UK.

It is agreed that within the UK there is a poor level of investment in formal training and development. This is particularly evident within the small firm sector. The literature, which considers this issue, concludes that there are a number of reasons why small firm owners are, on the whole, reluctant to invest in such training for themselves and their employees. Such reasons include, ignorance of benefits, time issues, fear that training will enhance employee mobility and, critically, that there is little evidence to indicate that investment in training and development leads to enhanced firm performance. On the basis that there has been some debate and empirical investigation regarding why training does not take place, this paper takes an alternative stance and considers what issues and processes might underpin the decision to invest in training ‐ particularly management training. Findings are drawn from empirical research on a sample of firms where investment had been made in such training in the last 24 months; the indications being that such investment was not strategic or proactive but prompted by problems which threatened business performance.

The purpose of this paper is to provide some insights regarding the adoption of internet advertising by Iranian small and medium‐sized enterprises. The recent negative trends leading to a lack of competitive advantage in small businesses and the advantages of internet advertising makes it imperative to study various factors affecting this area of marketing.

This study reviewed 59 previous related studies, resulting in a comprehensive theoretical framework which explains the advantages of internet advertising for small to medium‐sized enterprises (SMEs). Via questionnaire, the paper compiles 346 Iranian experts’ opinions in order to test the validity and applicability of variables in Iran. A structural equation model and LISREL software were used to analyze the data.

A total of seven latent variables of internet advertising adoption were examined: advertising agencies, internet publishers, small and middle‐sized enterprises, government role, e‐commerce development and user types. The paper found that these constructs successfully explain internet advertising adoption by incorporating readiness and globalization stages. The small and medium‐sized enterprises were found to be the most significant for explaining internet advertising adoption.

The sample was restricted to Iranian experts.

This study offers one of the first attempts to build a comprehensive theoretical model explaining internet advertising adoption. Second, this study offers a new scale for internet advertising adoption with higher content validity.

This paper aims to consider the nature of cannabis-related harms under the UK’s Misuse of Drugs Act (MDA). Written for the specific context of this four-paper special section on 50 years of the MDA, it argues that the MDA may cause more harm than it prevents.

An opinion piece offering a structured overview of cannabis-related harms under prohibition. It summarises existing evidence of the ways in which prohibition may exacerbate existing – and create new – harms related to the production, distribution, use and control of cannabis.

The paper argues that prohibition of cannabis under the MDA may cause more harm than it prevents.

It has long been argued that the MDA does not accurately or fairly reflect the harms of the substances it prohibits, and much existing research points to different ways in which drug prohibition can itself be harmful. The originality of this paper lies in bringing together these arguments and developing a framework for analysing the contribution of prohibition to drug-related harm.
