A range of strategies to improve pharmaceutical care has been implemented by population health management (PHM) initiatives. However, which strategies generate the desired outcomes is largely unknown. The purpose of this paper is to identify guiding principles underlying collaborative strategies to improve pharmaceutical care and the contextual factors and mechanisms through which these principles operate.

The evaluation was informed by a realist methodology examining the links between PHM strategies, their outcomes and the contexts and mechanisms by which these strategies operate. Guiding principles were identified by grouping context-specific strategies with specific outcomes.

In total, ten guiding principles were identified: create agreement and commitment based on a long-term vision; foster cooperation and representation at the board level; use layered governance structures; create awareness at all levels; enable interpersonal links at all levels; create learning environments; organize shared responsibility; adjust financial strategies to market contexts; organize mutual gains; and align regional agreements with national policies and regulations. Contextual factors such as shared savings influenced the effectiveness of the guiding principles. Mechanisms by which these guiding principles operate were, for instance, fostering trust and creating a shared sense of the problem.

The guiding principles highlight how collaboration can be stimulated to improve pharmaceutical care while taking into account local constraints and possibilities. The interdependency of these principles necessitates effectuating them together in order to realize the best possible improvements and outcomes.

This is the first study using a realist approach to understand the guiding principles underlying collaboration to improve pharmaceutical care.

The purpose of this paper is to gain insight into how population health management (PHM) strategies can successfully integrate and reorganize public health, health care, social care and community services to improve population health and quality of care while reducing costs growth, this study compared four large-scale transformation programs: Greater Manchester Devolution, Vancouver Healthy City Strategy, Gen-H Cincinnati and Gesundes Kinzigtal.

Following the realist methodology, this explorative comparative case-study investigated PHM initiatives' key features and participants' experiences of developing such initiatives. A semi-structured interview guideline based on a theoretical framework for PHM guided the interviews with stakeholders (20) from different sectors.

Five initial program theories important to the development of PHM were formulated: (1) create trust in a shared vision and understanding of the PHM rationale to establish stakeholders' commitment to the partnership; (2) create shared ownership for achieving the initiative's goals; (3) create shared financial interest that reduces perceived financial risks to provide financial sustainability; (4) create a learning environment to secure initiative's credibility and (5) create citizens' and professionals' awareness of the required attitudes and behaviours.

The study highlights initial program theories for the implementation of PHM including different strategies and structures underpinning the initiatives. These insights provide a deeper understanding of how large-scale transformation could be developed.

This paper aims to explore the attitude-behaviour gap consumers experience when transitioning from buying fast fashion to embracing sustainable fashion consumption. Despite being driven to make sustainable fashion purchases, consumers are confronted with certain retail barriers that impede them from making the shift.

This study draws from the theory of planned behaviour and the behavioural-reasoning theory approaches to theoretically develop and assess five key fashion consumption barriers that moderate the relationship between sustainable fashion consumption motivations and actual behaviour. These are the steep price of sustainable fashion, low visibility, restricted availability, limited cognisance of the deleterious consequences of fast fashion and low trust in sustainability claims. Under heightened levels of moderators, the relationship between motivation and behaviour was predicted to be weaker. The author's data sample of 376 consumers validated the hypotheses.

This article contributes to the field of sustainable fashion retail consumption in three ways: (1) it reveals that the expensive cost of sustainable fashion is not an obstacle to its adoption, and consumers are willing to pay more but struggle to access the styles they prefer; (2) it unveils that, in contrast to recent scholarship, the lack of knowledge of the adverse environmental effects of fast fashion is still a barrier to transitioning to sustainability and (3) it implies that consumers are less motivated to lower their consumption of clothing when they feel dubious about fashion companies' sustainability claims.

The findings contribute to the existing body of knowledge on green consumption by shedding light on the complex dynamics between moderating factors and the transition from intention to behaviour in sustainable fashion consumption.
