In the context of organizational change, identifying, and organizing the various roles of change agents remains a challenge for practitioners and scholars alike. This chapter examines how different agents can enable an effective change process. Empirical evidence from three hospitals illustrates the process of transformation and its underlying arrangements to identify agents and their roles. The findings underline the importance of designing a coherent system of agents, determining where they come from, their role during the process, and how this may change throughout the change process. Managerial choices in the cases are discussed, leading to implications for theory and practice.

This article explores officer use of suspicion before informal police-citizen encounters as a method to further understand police officer decision-making. There is a body of research focused on officer decision-making before formal “stop and search” encounters, yet, while the more informal “stop and chat” encounters are ubiquitous, they are a comparatively under-researched part of policework.

The research takes an ethnographic approach to explore police decision-making. It used participant observation (800 h over 93 patrol shifts) of front-line first response officers from New Zealand (n = 45) and South Australia (n = 48). Field observations were complemented with informal discussion in the field and 27 semi-structured interviews.

It reveals that officers applied three situational “tests” to assess the circumstances or actions observed before initiating an informal encounter. Officers then weighed up whether the circumstances were harmful, contrary to law, or socially acceptable to determine the necessity of initiating a police-citizen encounter. This process is conceived as suspicioning: deciding whether circumstances appear prima facie suspicious, how an officer goes about collecting more information to corroborate suspicion to ultimately inform a course of action.

The findings present a new perspective to understanding how and why police officers decide to initiate encounters with members of the public. Moreover, as the first ethnographic cross-national research of officers from New Zealand and South Australia, it provides a rare comparative glimpse of Antipodean policing.

This paper aims to address a gap in investigating specific impacts of climate change on mental health in the Pacific region, a region prone to extreme events. This paper reports on a study on the connections between climate change, public health, extreme weather and climate events (EWEs), livelihoods and mental health, focusing on the Pacific region Islands countries.

This paper deploys two main methods. The first is a bibliometric analysis to understand the state of the literature. For example, the input data for term co-occurrence analysis using VOSviewer is bibliometric data of publications downloaded from Scopus. The second method describes case studies, which outline some of the EWEs the region has faced, which have also impacted mental health.

The results suggest that the increased frequency of EWEs in the region contributes to a greater incidence of mental health problems. These, in turn, are associated with a relatively low level of resilience and greater vulnerability. The findings illustrate the need for improvements in the public health systems of Pacific nations so that they are in a better position to cope with the pressures posed by a changing environment.

This paper contributes to the current literature by identifying the links between climate change, extreme events, environmental health and mental health consequences in the Pacific Region. It calls for greater awareness of the subject matter of mental health among public health professionals so that they may be better able to recognise the symptoms and relate them to their climate-related causes and co-determinant factors.

The purpose of this paper is to investigate what happens when a lack of role-sending results in ambiguous change agent roles during a large scale organisational reconfiguration. The authors consider the role of sensemaking in resolving role ambiguity of middle manager change agents and the consequences of this for organisational restructuring.

Data were collected from a case study analysis of significant organisational reconfiguration across a local National Health Service Trust in the UK. Data consists of 82 interviews, complemented by analysis of over 100 documents and field notes from 51 hours of observations collected over five phases covering a three year period before, during and after the reconfiguration. An inductive qualitative analysis revealed the sensemaking processes by which ambiguity in role definition was resolved.

The data explains how change agents collectively make sense of a role in their own way, drawing on their own experiences and views as well as cues from other organisational members. The authors also identified the organisational outcomes which resulted from this freedom in sensemaking. This study demonstrates that by leaving too much flexibility in the definition of the role, agents developed their own sensemaking which was subsequently very difficult to manipulate.

In creating new roles, management first needs to have a realistic vision of the task and roles that their agents will perform, and second, to communicate these expectations to both those responsible for recruiting these roles and to the agents themselves.

Much of the focus in sensemaking research has been on the importance of change agents’ sensemaking of the change but there has been little focus on how change agents sensemake their own role in the change.

The attention of all concerned is drawn to the need for guarding against the effects of poisonous fumes when using chemical fire extinguishers of the types usually carried in civil aeroplanes. One of the dangers to be guarded against is that at low concentrations the fumes may have no smell, or such smell as there is may not be unpleasant, and may not suggest that breathing the air is in any way dangerous. Exposure for half an hour or so to such fumes may nevertheless produce subsequent ill effects, though none may be noticed until some hours after the exposure has ceased.

Whereas, the classical Green-Naghdi Type II (GN-II) model struggles to accurately represent the thermo-mechanical behavior of thermoelectric MHD due to its inability to account for the memory effect. A new mathematical model of the GN-II theory incorporates a fractional order of heat transport to address this issue.

The employment of the matrix exponential method, which forms the basis of the state-space approach in contemporary theory, is central to this strategy. The resulting formulation, together with the Laplace transform techniques, is applied to a variety of problems. Solutions to a thermal shock problem and to a problem of a layer media both without heat sources are obtained. Also, a problem with the distribution of heat sources is considered. The numerical technique is used to achieve the Laplace transform inversion.

According to the numerical results and its graphs, the influences of the fractional order parameters, figure-of-merit factor, thermoelectric power and Peltier coefficient on the behavior of the field quantities are investigated in the new theory.

The new modeling of thermoelectric MHD has advanced significantly as a result of this work, providing a more thorough and precise tool for forecasting the behavior of these materials under a range of thermal and magnetic conditions.

The purpose of this paper is to better understand how and why adoption and implementation of healthcare IT innovations occur. The authors examine two IT applications, computerised physician order entry (CPOE) and picture archiving and communication systems (PACS) at the meso and micro levels, within the context of the National Programme for IT in the English National Health Service (NHS).

To analyse these multi-level dynamics, the authors blend Rogers’ diffusion of innovations theory (DoIT) with Webster’s sociological critique of technological innovation in medicine and healthcare systems to illuminate a wider range of interacting factors. Qualitative data collected between 2004 and 2006 uses semi-structured, in-depth interviews with 72 stakeholders across four English NHS hospital trusts.

Overall, PACS was more successfully implemented (fully or partially in three out of four trusts) than CPOE (implemented in one trust only). Factors such as perceived benefit to users and attributes of the application – in particular speed, ease of use, reliability and flexibility and levels of readiness – were highly relevant but their influence was modulated through interaction with complex structural and relational issues.

Results reveal that combining contextual system level theories with DoIT increases understanding of real-life processes underpinning implementation of IT innovations within healthcare. They also highlight important drivers affecting success of implementation, including socio-political factors, the social body of practice and degree of “co-construction” between designers and end-users.

The originality of the study partly rests on its methodological innovativeness and its value on critical insights afforded into understanding complex IT implementation programmes.

This paper aims to investigate the interaction of the relationships between group behaviour, group process and learning outcomes in online executive education.

A systematic review of literature in the relevant conceptual domains is performed.

A framework is proposed from the systematic review and proposes a dynamic classroom environment where instructor capability interacts with group process and behaviour to generate new learning outcomes. The impact of institutional context and technology infrastructure are highlighted as drivers of both the classroom and instructor effectiveness.

The systematic review highlights several future research trajectories posing the questions: How disruptive innovation impacts on instructor capability development? How alternative theories explain the routines underpinning instructor capability? What is the role of external partners in the development of learning in context? What is the nature of instructor innovation capability? and How does instructor technology capability impact on learning outcomes?

Human resource development practitioners are presented with insights as to their existing and potential future roles in enhancing group behaviour, process and learning outcomes in executive classrooms impacted by technological change. The subsequent potential for practitioner enabled learning innovation is highlighted.

This paper contributes to contemporary debates regarding the interaction of emerging technologies and the executive online classroom, specifically focusing on the area of group behaviour process and learning.

Past research on the immigrant health paradox suggests that children with immigrant parents may have a health advantage over those with US-born parents, especially if the parent is a recent immigrant. Other research emphasizes the social and economic challenges children with immigrant parents face, in part due to disadvantaged social class and racial/ethnic positions. Underlying physiological changes due to chronic stress exposures among children in immigrant families is one potential health disadvantage that may not yet be apparent in traditional health measures. To explore these biological disparities during childhood, I use national biomarker and survey data from the National Health and Nutrition Survey (NHANES) (N = 11,866) to evaluate parent nativity and educational status associations with low-grade inflammation, indicated by C-reactive protein (CRP), in children ages 2–15 years. I find that children with an immigrant parent, and particularly a low-educated immigrant parent, have higher CRP, net of birth, body mass index (BMI) and other factors, than children with a US-born parent with either a low or higher education. Comparing children with low-educated parents, those with a foreign-born parent have higher predicted CRP. The findings from this study provide new evidence that children living in immigrant families in the US may be facing higher levels of chronic stress exposure, as indicated by the increased risk of low-grade inflammation, than those with US-born parents. The physiological changes related to increased risk of inflammation, could set children in immigrant families on pathways toward mental and physical health problems later in the life course.
