Workplace Social Relations in theReturn-to-Work processTjulin, Åsa January 2010 (has links)
The overall aim of this thesis was to explore the impact of workplace social relations on the implementation of return-to-work interventions. The thesis consists of four separate papers with specific aims. In Paper I, the overall purpose of the study was to analyse how a multi-stakeholder return-to-work programme was implemented and experienced from the perspective of the stakeholders involved, i.e. supervisors, occupational health consultants and a project coordinator. The objective was to identify and analyse how these stakeholders perceived that the programme had been implemented in relation to its intentions. In Paper II, the objective was to explore how workplace actors experience social relations, and how organisational dynamics in workplace-based return-to-work start before and extend beyond the initial return of the sick-listed worker to the workplace. In Paper III, the objective was to explore the meaning of early contact in return-to-work, and how social relational actions and conditions can facilitate or impede early contact among workplace actors. In Paper IV, the objective was to explore the role of co-workers in the return-to-work process, and their contribution to the process, starting from when a colleague falls ill, continuing when he/she subsequently becomes sick-listed and finally when he/she re-enters the workgroup. The general methodological approach to the papers in this thesis has been explorative and interpretive; qualitative methods have been used, involving interviews, group interviews and collection of employer policies on return-to-work. The data material has been analysed through back-and-forth abductive (Paper I), and inductive (Papers II-IV) content analysis. The main findings from Paper I show that discrepancies in the interpretations of policy intentions between key stakeholders (project coordinator, occupational health consultants and supervisors) created barriers for implementing the employer-based return-to-work programme, due to lack of communication, support, coaching and training activities of key stakeholders dedicated to the biopsychosocial intentions of the programme. In Papers II-IV, the workplace actors (re-entering workers, co-workers, supervisors and/or human resources manager) experienced the return-to-work process as phases (time before the sick leave, when on sick leave, when re-entering the workplace, and future sustainability). The findings highlight the importance and relevance of the varied roles of the different workplace actors during the identified phases of the return-to-work process. In particular, the positive contribution of co-workers, and their experience of shifting demands and expectations during each phase, is acknowledged. During the period of time before sick leave the main findings show how workplace actors experience the meaning of early contact within a social relational context, and how early contact is more than an activity that is merely carried out (or not carried out). The findings show how workplace actors experience uncertainties about how and when contact should take place, and the need to balance possible infringement that early contact might cause for the re-entering worker between pressure to return to work and their private health management. The findings in this thesis show how the workplace is a socially complex dynamic setting, which challenges some static models of return-to-work. The biopsychosocial and ecological/case management models and policies for return-to-work have been criticised for neglecting social relations in a return-to-work process at the workplace. This thesis provides increased knowledge and explanations regarding important factors in workplace social relations that facilitate an understanding of what might “make or break” the return-to-work process.

Clustering Algorithm for Zero-Inflated DataJanuary 2020 (has links)
Zero-inflated data are common in biomedical research. In cluster analysis, the heuristic
approach fails to provide inferential properties to the outcome while the existing model-based
approach only works in the case of a mixture of multivariate normal. In this dissertation, I
developed two new model-based clustering algorithms- the multivariate zero-inflated log-normal
and the multivariate zero-inflated Poisson clustering algorithms. I then applied these methods to
the questionnaire data and compare the resulting clusters to the ones derived from assuming
multivariate normal distribution. Associations between clustering results and clinical outcomes
were also investigated.

Effectiveness guidance document (EGD) for Chinese medicine trials: a consensus documentWitt, Claudia, Aickin, Mikel, Cherkin, Daniel, Che, Chun, Elder, Charles, Flower, Andrew, Hammerschlag, Richard, Liu, Jian-Ping, Lao, Lixing, Phurrough, Steve, Ritenbaugh, Cheryl, Rubin, Lee, Schnyer, Rosa, Wayne, Peter, Withers, Shelly, Zhao-Xiang, Bian, Young, Jeanette, Berman, Brian, Collaborators January 2014 (has links)
BACKGROUND:There is a need for more Comparative Effectiveness Research (CER) on Chinese medicine (CM) to inform clinical and policy decision-making. This document aims to provide consensus advice for the design of CER trials on CM for researchers. It broadly aims to ensure more adequate design and optimal use of resources in generating evidence for CM to inform stakeholder decision-making.METHODS:The Effectiveness Guidance Document (EGD) development was based on multiple consensus procedures (survey, written Delphi rounds, interactive consensus workshop, international expert review). To balance aspects of internal and external validity, multiple stakeholders, including patients, clinicians, researchers and payers were involved in creating this document.RESULTS:Recommendations were developed for "using available data" and "future clinical studies". The recommendations for future trials focus on randomized trials and cover the following areas: designing CER studies, treatments, expertise and setting, outcomes, study design and statistical analyses, economic evaluation, and publication.CONCLUSION:The present EGD provides the first systematic methodological guidance for future CER trials on CM and can be applied to single or multi-component treatments. While CONSORT statements provide guidelines for reporting studies, EGDs provide recommendations for the design of future studies and can contribute to a more strategic use of limited research resources, as well as greater consistency in trial design.
