Positive affect and behavior change
Affect and emotion have potent motivational properties that can be leveraged to promote desirable behavior change. Although interventions often employ fear appeals in an effort to motivate change, both theory and a growing body of empirical evidence suggest that positive affect and emotions can promote change by serving as proximal rewards for desired behaviors. This article reviews examples of such efforts in the domains of healthy diet and exercise, prosocial behavior, and pro-environmental behavior, documenting the strong potential offered by behavioral interventions using this approach. The extent to which positive affect experience prospectively drives behavior change (as distinct from rewarding the desired behavior) is less clear. However, a variety of possible indirect pathways involving incidental effects of positive affect and specific positive emotions deserve rigorous future study

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
Apples and oranges: Three criteria for positive emotion typologies
Positive emotion typologies, that is, classifications of positiveemotions into conceptually distinct categories or ‘types’ according to their properties, can clarify and simplify thecomplex structure of positive emotion space. In this review, we introduce three key evaluative criteria for such typologies: comprehensiveness, distinctiveness, and granularity.Comprehensiveness is the degree to which the typology accurately represents the boundaries of positive emotionspace; distinctiveness is whether emotional states are clustered on the basis of a consistent aspect of emotion; and granularity is the level of nuance and detail in categorization.These criteria provide standards by which the quality of existing typologies can be judged, as well as guiding the development of new typologies. Multiple valid and useful positive emotion typologies can be described; these criteria can guide scholars in selecting the typology that best suits their needsHuman-Centered Desig
What are "Positive" Affect and Emotion?
Positive affect and emotion have become major topics in behavioral science, of growing importance in basic and applied research. A broad review of the literature reveals multiple, theoretically distinct constructs associated with the terms ‘positive affect’ and ‘positive emotion,’ sometimes conflated across this body of work. This article differentiates three primary constructs — subjectively pleasant affect; approach or appetitive motivation; and emotion states evoked by opportunities and rewards in the environment — and summarizes the major theoretical perspective with which each is intertwined. While these versions of positivity often coincide in lived emotional experience, we highlight examples of divergence, and discuss dynamic ways in which they influence each other. Distinct cognitive, physiological, and behavioral mechanisms by which each version of positivity may produce downstream effects are discussed, as is the importance of selecting and operationalizing the target construct with care in both basic affective science and translational research.Accepted Author ManuscriptHuman-Centered Desig
Cultural Differences in Expectations of Change and Tolerance for Contradiction: A Decade of Empirical Research
A cytotoxic phenotype does not predict clinical outcome in anaplastic large cell lymphomas.
AIM: To investigate whether anaplastic large cell lymphomas (ALCL) expressing cytotoxic proteins have a relatively worse clinical outcome compared with ALCL lacking a cytotoxic phenotype. METHODS: 59 primary cases of ALCL originating from different sites were investigated by immunohistochemistry for the presence of the cytotoxic proteins T cell intracytoplasmic antigen (TIA-1) and granzyme B in the neoplastic cells. Since site of origin and expression of anaplastic lymphoma kinase (ALK) strongly influence prognosis, the presence of a cytotoxic phenotype was also investigated in relation to the primary site of origin (lymph node, gut, or skin) and ALK expression. The prognostic value was investigated by analysis of overall and relapse-free survival time, including Cox regression analysis. RESULTS: 39 of 59 ALCL (66%) appeared to have a cytotoxic phenotype as shown by expression of TIA-1 or granzyme B or both in the neoplastic cells. The presence of a cytotoxic phenotype did not have any influence on prognosis. Even when the survival data were corrected for site of origin and stage at presentation or were analysed separately for ALK positive and negative cases, no prognostic influence of a cytotoxic phenotype was observed. CONCLUSIONS: In primary biopsies of patients with ALCL, the presence of a cytotoxic phenotype is not related to clinical outcome of the disease
