Abstract
The calculation of undercarriage landing reactions and dynamic stresses is discussed, and the merging of the two calculations under certain circumstances is proposed. ? formulation of the combined problem is outlined, and numerical examination of a simple case shows that in some cases the reaction forces are appreciably reduced by the adoption of the combined approach. Finally, a criterion is derived which could be used in the early stages of undercarriage design to predict the elicci of aircraft flexibility.

Abstract
A growing interdisciplinary literature explores how people can simultaneously hold strong convictions and remain open to the possibility of learning from others with whom they disagree. This tension impacts not only knowledge development but also public discourse within a diverse and disagreeing democracy. This volume of Political Power and Social Theory considers the specific question of how religious convictions inform how people engage in democratic life, particularly across deep political divides. In this introduction, I begin by discussing how a narrow vision of religious citizens as dogmatic believers has led observers to frame religion as a concerning source of democratic distortion – encouraging too much arrogance and not enough humility. Yet this dogmatic believer narrative captures only one aspect of American religion. Juxtaposing a snapshot of dogmatic believers alongside two other snapshots of religious groups engaging in political life raises complex questions about the relationship between religious conviction, humility, and democracy in a time of deep political polarization. I argue that answering these questions requires a sociological approach that is attuned to power, context, culture, institutions, and history. At the same time, I show how attention to the tension between conviction and humility has the potential to enrich the sociological study of religion and democracy, and particularly ethnographic research across the moral/political divide.

Abstract
Clarifying constructs, methods, and measures for systematic research can advance knowledge about spirituality in organizations. In this paper, we define constructs of pure spirituality, applied spirituality, and spiritual development. We survey research methods for exploring spirituality in organizations – including not only objective studies but also subjective experience for personal growth. We consider five indications of spirituality – health, happiness, wisdom, success, and fulfillment – and identify research instruments for each based on measures used in prior studies of Maharishi Mahesh Yogi's Transcendental Meditation program. Research is seen as valuable for assessing the practical applications of spirituality for the individual, organization, and society.

Abstract
The purposes of this study were twofold. The first was to develop a model and the second was to propose a set of task descriptions appropriate and necessary for implementing the model. The model developed has three crucial stages, i.e., Planning, Implementing, and Evaluating. Within each stage are four common steps, i.e., Analyzing, Developing, Operating, and Evaluating. The three stages and the four steps within each stage were derived from an exploration of various schools of thought represented in the literature on inservice projects and models. Several extant models were discovered, and two in particular influenced the development of this one, but all were perceived to have certain deficiencies. This new model was designed to incorporate the best features of the others, while eliminating their deficiencies. Since the development of the model was based on the advocacy and validity of stages and steps as established in the literature, the model was judged to be theoretically and philosophically valid.

Abstract
Purpose
Three-dimensional (3D)printed skulls for neurosurgical training are increasingly being used due to the widespread access to 3D printing technology, their low cost and accuracy, as well as limitations and ethical concerns associated with using human cadavers. However, little is known about the risks of airborne particles or volatile organic compounds (VOCs) released while drilling into 3D-printed plastic models. The aim of this study is to assess the level of exposure to airborne contaminants while burr hole drilling.
Design/methodology/approach
3D-printed skull samples were produced using three different materials (polyethylene terephthalate glycol [PETG], white resin and BoneSTN) across three different 3D print processes (fused filament fabrication, stereolithography [SLA] and material jetting). A neurosurgeon performed extended burr hole drilling for 10 min on each sample. Spot measurements of particulate matter (PM2.5 and PM10) were recorded, and air samples were analysed for approximately 90 VOCs.
Findings
The particulate matter for PETG was found to be below the threshold value for respirable particles. However, the particulate matter for white resin and BoneSTN was found to be above the threshold value at PM10, which could be harmful for long periods of exposure without personal protective equipment (PPE). The VOC measurements for all materials were found to be below safety thresholds, and therefore not harmful.
Originality/value
To the best of the authors’ knowledge, this is the first study to evaluate the safety of 3D-printed materials for burr hole surgical drilling. It recommends PETG as a safe material requiring minimal respiratory control measures, whereas resin-based materials will require safety controls to deal with airborne particles.

Abstract
Drawing on a case study of a Swedish top management team whose members were practitioners of the Transcendental Meditation1 (TM1) technique, this article argues for developmental maturity as an important causal factor for effective TQM behaviors and success. It suggests that, first, increased maturity permits expression of more effective cognitive, affective, and team TQM behaviors, as indicated by improved team functioning and successful TQM planning, and, second, practice of the TM technique promotes the psychological maturation that allows a greater range of appropriate TQM behaviors. Thus, the inner development provided by the Transcendental Meditation program has practical value for managers engaged in TQM implementation.

Abstract
IT is a tradition that journals of almost every type, as a New Year becomes imminent, should express optimism concerning if not the future as a whole, at least as far as the year to come is concerned. Would that be justified as we approach the eighties?

Abstract
Purpose – Research on hospital system organization is dated and cross-sectional. We analyze trends in system structure during 2000–2010 to ascertain whether they have become more centralized or decentralized.
Design/Methodology/Approach – We test hypotheses drawn from organization theory and estimate empirical models to study the structural transitions that systems make between different “clusters” defined by the American Hospital Association.
Findings – There is a clear trend toward system fragmentation during most of this period, with a small recent shift to centralization in some systems. Systems decentralize as they increase their members and geographic dispersion. This is particularly true for systems that span multiple states; it is less true for smaller regional systems and local systems that adopt a hub-and-spoke configuration around a teaching hospital.
Research Limitations – Our time series ends in 2010 just as health care reform was implemented. We also rely on a single measure of system centralization.
Research Implications – Systems that appear to be able to centrally coordinate their services are those that operate in local or regional markets. Larger systems that span several states are likely to decentralize or fragment.
Practical Implications – System fragmentation may thwart policy aims pursued in health care reform. The potential of Accountable Care Organizations rests on their ability to coordinate multiple providers via centralized governance. Hospitals systems are likely to be central players in many ACOs, but may lack the necessary coherence to effectively play this governance role.
Originality/Value – Not all hospital systems act in a systemic manner. Those systems that are centralized (and presumably capable of acting in concerted fashion) are in the minority and have declined in prevalence over most of the past decade.

Abstract
This paper analyzes health care as a context for building value through human capital and culture. We examine how health care managers can nurture a favorable culture for providers enabling them to focus on customer service. A case study of a large medical center examines how organization culture affects clinicians versus support and managerial staff while adversely impacting patient satisfaction and organizational costs associated with turnover and the cost of replacing personnel. An agenda for managing internal customers and organization culture is presented.

Abstract
Purpose
Patients with autism spectrum disorder (ASD) present with specific assessment, specific difficulties, needs and therapeutic issues and therefore are a challenging group for forensic services. Given the challenge that individuals with ASD present to forensic services, the suggested increase in the number of this group within this setting and the relatively little amount of research which suggests they face a number of difficulties within the prison environment, the purpose of this paper is to identify and review all the studies which have been carried out investigating any aspect of ASD in relation to secure hospital settings.
Design/methodology/approach
Seven internet-based bibliographic databases were used for the present review. The review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.
Findings
A total of 12 studies were included in this review; 3 looked at the prevalence of ASD in secure psychiatric hospitals. One study evaluated the clinical utility of the AQ screening tool to assess self-reported autistic traits in secure psychiatric settings. Three explored any type of characteristics of patients with ASD detained in secure psychiatric hospitals. One study investigated the experiences or quality of life of patients with an ASD detained in secure psychiatric care. Two studies investigated awareness, knowledge and/or views regarding patients with ASD held by staff working within secure psychiatric hospitals. Lastly, three studies (one of which was also included in the prevalence category above) looked at the effectiveness of interventions or treatment of patients with ASD in secure psychiatric hospitals. Clinical recommendations and future research directions are discussed.
Originality/value
To the author’s knowledge, this is the first review to explore what research has been carried out looking specifically at patients with ASD in relation to secure forensic settings.
