BACKGROUND Health care professionals (HCPs) are challenged in caring for persons with suicidal ideation or behavior. For affected persons, professional care is essential, and being interviewed about their experiences can be stressful. The experiences of persons ideating or attempting suicide are essential to designing eHealth products to support them in crises and provide continuous care. OBJECTIVE This study aimed to synthesize published qualitative research about how persons with suicidal thoughts or behavior experience inpatient or outpatient care. A model will be derived from the meta-synthesis to guide HCPs in their work with affected persons and provide a thorough needs assessment for eHealth development. METHODS A qualitative meta-synthesis was conducted using an inductive approach, as proposed by Sandelowski and Barroso. The inclusion criteria were studies in English and German that dealt with persons who ideated or attempted suicide. Relevant articles were identified by searching the PubMed and Cinahl databases and by hand searching relevant journals and reference lists. The findings of each study were analyzed using initial and axial coding, followed by selective coding. Finally, a conceptual model was derived. RESULTS In total, 3170 articles were identified in the systematic literature search. Articles were screened independently by 2 researchers based on the eligibility criteria. Finally, 12 studies were included. The central phenomenon observed among persons ideating or attempting suicide is their process from feeling unanchored to feeling anchored in life again. During inpatient and outpatient care, they experience being dependent on the skills and attitudes of HCPs. While helpful skills and attitudes support persons ideating or attempting suicide to reach their feeling of being anchored in life again, adverse interactions are experienced negatively and might lead to prolonging or maintaining the feeling of being unanchored in life. CONCLUSIONS The study promotes a differentiated view of the experiences of persons ideating or attempting suicide. The derived conceptual model can guide HCPs in their work with affected persons to support affected persons during their recovery. Moreover, the conceptual model is useable as a springboard to develop eHealth solutions for crisis situations and long-term care.

This study aims at presenting a conceptual model for landscape management in the Himalayan region of India, using quantitative/mathematical approach. Keeping in view the requirement, (based on fifteen years empirical field work in the Himalayan region and as well as literature survey) the MODAM (Multiple Objectives Decision Support Tools for Landscape Management) model along with linear programming approach was adopted with a view to presenting additional methodological perspectives on interdisciplinary landscape research. The work has stemmed out from the original research contribution, which tries to integrate interdisciplinary research planning with landscape management related research in the Himalayan region. This biodiversity hotspot has relatively high complexity in terms of sustainable socioeconomic development vis a vis conservation and management of the resources. The concepts and insights presented in this article will provide the basis for a discussion, on decision-making issues among multidisciplinary experts with regard to sustainable socioecological development within complex environments.

A procedure is presented for designing multivariable controllers for unidentified plant. It is assumed that the open-loop plant is stable and its response to step inputs are basically nonoscillatory. For such plant, no mathematical model is required in order to generate multivariable I, PI, or PID controllers. Method of tuning the controllers are also presented and demonstrated, first on a low order linear distillation column model, and finally on a high order, nonlinear, once-through boiler model typical of the type used in nuclear power plant simulation studies.

Purpose The purpose of this paper is to study the factors influencing doctors’ involvement in Lean change initiatives in public healthcare organizations in Canada. Design/methodology/approach An inductive research was conducted over a three-year span studying Lean implementation across three healthcare organizations in Canada. Various interviews were conducted with healthcare actors. Through analytical induction, analysis of the data allowed for multiple factors to be triangulated from which a conceptual model was developed. Findings Fifty-four interviews with 18 Lean healthcare actors allowed for the identification of ten factors possibly influencing the commitment of doctors towards Lean change. These factors are categorized into pre-change antecedents and change antecedents. Also, the level of transformational leadership demonstrated by a project manager was shown to potentially moderate the effect of medical behavioral support for change on change outcomes. These findings allowed us to develop a conceptual model of medical commitment and its impact of Lean change outcomes. Originality/value The paper investigates the role doctors play in Lean implementation, currently an important issue discussed among healthcare actors and researchers. Yet, very little academic research has been published on this subject.
