Studies suggest that fear-related responses might be acquired through the facial expressions of other individuals. The present study aimed to investigate the derived transfer of aversive functions in equivalence classes comprised of facial expressions of fear and happiness. A delayed matching-to-sample task established two equivalence classes between facial expressions of emotions and nonsense abstract stimuli: Bl-Al(Fear)-Cl-D1; B2-A2(Happiness)-C2-D2. After relational training (AB, AC, CD) and equivalence tests (BD, DB), the transfer of function from the faces to the D stimuli was evaluated by means of (1) a semantic differential, (2) an avoidance task, (3) US expectancy scale, and (4) valence scale. Results from the semantic differential indicated that D1 and D2 had negative and positive evaluations, respectively. Fear related measures indicated that D1 (equivalent to fear) evoked avoidance responses, was highly rated on US expectancy and was negatively valenced; in comparison, D2 (equivalent to happy) did not evoke either avoidance or US expectancy and was positively valenced. These findings indicate that the participation of fearful faces in equivalence classes leads to derived fear, including derived avoidance responses. Keywords equivalence relations * transfer of function * semantic differential - avoidance * fearful faces, Equivalence relations are central in a behavior-analytic account of symbolic behavior (Sidman, 1994; Sidman & Tailby, 1982; Hayes, Bames-Holmes, & Roche, 2001; de Rose & Bortoloti, 2007).

This report aims to enhance our understanding of stakeholder mapping for co-created citizen science initiatives. It presents and discusses findings from an international two-day stakeholder mapping workshop with researchers, event organizers, communication experts, and artists realizing citizen science activities. Participants identified examples of co-creation in their work and mapped stakeholders for three co-creation initiatives from the "Doing It Together Science" project. For each case, we provide an overview of the stakeholder groups involved and the lessons derived from identifying actual and potential stakeholders in different phases of each activity and using different ways for mapping them. We demonstrate that not only stakeholder mapping can be diverse, but it may take different angles depending on the characteristics and project timescales, nevertheless adding significant value to any project. We argue that a better understanding of stakeholder involvement may contribute to more effective stakeholder communication, more successful implementation, and a greater impact for citizen science initiatives.

Background: Approximately 2–4% of individuals worldwide with diabetes mellitus have foot ulcers. This study aims to assess the factors affecting the outcomes of severe foot ulcers in diabetic individuals. Methods: An analytical prospective cohort study was conducted from March 1st, 2015, to March 1st, 2017. A total of 34 individuals was selected. The study included patients with foot ulcers below the ankle who were at risk of amputation. All tests used a <5% level of significance and confidence interval of 95%. A Pearson's chi-squared test and binary multiple regression were performed to assess the factors related to healing. Results: Only 11.7% of the individuals required amputation; ulcers classified as 2/B according to the University of Texas Diabetic Foot Ulcer Classification System healed before the 1/B ulcers. Neuropathic ulcers were the most prevalent (58.8%); 61.8% healed after 1 year. Most of the individuals were overweight, 47.1% had reduced glomerular filtration rates, and 78.8% had glycated hemoglobin >7%. Body mass index and osteomyelitis were the two significant variables in logistic regression. Conclusions: In this study, osteomyelitis was the main complication related to the risk of amputation, and elevated body mass index and osteomyelitis were the significant factors that induced a slower healing time.
