The aim of the study was to evaluate calcium anacardate (CAn), associated or not with citric acid (CAc) in laying hen diets on performance, egg quality, serum biochemical profile, serum lipid peroxidation (TBARS) and catalase (CAT) in reproductive tissue. A total of 432 laying hens from 63 to 74 weeks of age, were distributed in nine diets: Control; 0.25% CAn; 0.25% of CAn associated with 0.25% CAc; 0.50% CAn; 0.50% CAn associated with 0.25% CAc; 0.50% CAn associated with 0.50% CAc; 0.75% of CAn; 0.75% CAn associated with 0.25% CAc; 0.75% CAn associated with 0.50% CAc. There was no effect of CAn or CAc on laying hen performance. Yolk colour showed greater pigmentation for 0.75% CAn and its associations with CAc (0.25% and 0.50%). Lower egg yolk oxidation was observed for an isolated dose of 0.75% CAn. Higher values of TBARs were observed in eggs from birds fed control diet; 0.25% CAn; 0.50% CAn associated with 25% CAc and 0.75% CAn associated with 0.25 and 0.50% CAc. Dietary inclusion of CAn (0.75%) and its association with CAc (0.50% CAn with 0.50 CAc) for late-phase laying hens reduce serum peroxidation. CAn from 0.50% associated with CAc increases catalase in magnum. The addition of 0.75% CAn increases yolk pigmentation, reduces lipid oxidation in the yolk and blood plasma and increases CAT activity in the magnum in late-stage laying hens. These benefits can also be obtained with the combination of 0.50% CAn and 0.50% CAc.
It remains unclear which individuals with subthreshold depression benefit most from psychological intervention, and what long-term effects this has on symptom deterioration, response and remission.
Aims
To synthesise psychological intervention benefits in adults with subthreshold depression up to 2 years, and explore participant-level effect-modifiers.
Method
Randomised trials comparing psychological intervention with inactive control were identified via systematic search. Authors were contacted to obtain individual participant data (IPD), analysed using Bayesian one-stage meta-analysis. Treatment–covariate interactions were added to examine moderators. Hierarchical-additive models were used to explore treatment benefits conditional on baseline Patient Health Questionnaire 9 (PHQ-9) values.
Results
IPD of 10 671 individuals (50 studies) could be included. We found significant effects on depressive symptom severity up to 12 months (standardised mean-difference [s.m.d.] = −0.48 to −0.27). Effects could not be ascertained up to 24 months (s.m.d. = −0.18). Similar findings emerged for 50% symptom reduction (relative risk = 1.27–2.79), reliable improvement (relative risk = 1.38–3.17), deterioration (relative risk = 0.67–0.54) and close-to-symptom-free status (relative risk = 1.41–2.80). Among participant-level moderators, only initial depression and anxiety severity were highly credible (P > 0.99). Predicted treatment benefits decreased with lower symptom severity but remained minimally important even for very mild symptoms (s.m.d. = −0.33 for PHQ-9 = 5).
Conclusions
Psychological intervention reduces the symptom burden in individuals with subthreshold depression up to 1 year, and protects against symptom deterioration. Benefits up to 2 years are less certain. We find strong support for intervention in subthreshold depression, particularly with PHQ-9 scores ≥ 10. For very mild symptoms, scalable treatments could be an attractive option.
Humans show remarkable differences in social behaviour between families, groups, communities and cultures, whereas such group-level within-species variation in socio-behavioural propensities is typically overlooked in other species. Studies on intraspecific variation in animal social structures are needed to inform an evolutionary account of human sociality. Here, we study multiple independent bonobo populations (n = 6) in zoological settings to investigate if and how bonobos (n = 70) show group-specific signatures in sociality. By applying tailored Bayesian statistical methods, we find that beyond individual and dyadic variation, the groups substantially differ from each other in core dimensions of great ape sociality: social proximity, grooming and play. Moreover, the groups’ network structures are distinct regarding cohesiveness and clustering, with some groups forming cohesive wholes, while others showcasing high levels of sub-grouping. Overall, while there is consistent evidence of differences in sociality between the groups, the patterns of cohesiveness and clustering are not consistent across the networks. This suggests that rather than groups having different levels of sociality, different patterns of sociality exist in each group. These findings warrant caution with characterising bonobos’ behavioural phenotype at the species level, and identify an essential source of variation that needs to be integrated in phylogenetic analyses.
Chapter 4 presents the results of a study by Palaganas, involving participants in an online continuing education course that used an emoji-capable, text-based platform, offered through the Center for Medical Simulation in Boston, Massachusetts. The chapter outlines the study, the compiled data, and the relevant findings. The study yields further insights into the potential for using the emoji code as an effective literacy and communication tool in a higher education context – namely, in a healthcare professional education program. Further, there is discussion of an interview with Dr. Shuhan He, a prominent proponent of emoji use in healthcare situations, wherein he goes over the impetus for his creation of the heart emoji.
The goal of Chapter 5 is to examine emoji use across the healthcare landscape, as well as what implications related to emoji theories can be gleaned from such usage and how emoji use can be applied to training healthcare professionals more generally. Prominently discussed in the chapter are clinical studies that indicate emoji writing (between practitioners and patients) may actually enhance medical outcomes. Also highlighted is the empirically attested fact that emoji scales and models may be good gauges for assessing well-being. The overall conclusion that can be drawn from the studies is that emoji might affect patients positively. Emoji are not medical cures in themselves, needless to say; they are simple pictures that affect patients positively, much like humor. They may also counteract the so-called nocebo effect, defined as a detrimental effect on health produced by psychological or psychosomatic factors such as negative expectations of treatment or prognosis.
Chapter 7 distills from the empirical studies their implications for emoji theories overall and for their applicability to the educational and healthcare realms. The studies have borne a number of concrete implications for emoji theory in general, including how they fit in with communication theories, including nonverbal aspects. Several theoretical notions are developed as well, generalizing them from previous chapters, including the apparent function of emoji as “annotators” of meaning, not just conveyors of prosodic or gestural features in writing. Another notion is that of episodic meaning, whereby the placement of an emoji in the episodes that constitute a message adds to it semiotically. Emoji grammar is thus more appropriately characterized as an episodic grammar.
Using both the Petcoff and Palaganas studies as a point of departure, this chapter looks at the more general educational implications of bringing emoji into pedagogical practices. The underlying premise is that emoji not only are highly understandable images, aiding learning but also can create a positive environment, making teaching and interaction congenial and open to all learners, no matter their backgrounds or learning capacities, since emoji give them an equal voice. Emoji allow for a destigmatized approach, especially for disadvantaged learners who might not be able to adequately speak for themselves. Emoji are a psychological conduit that can easily open up lines of interaction to virtually everyone. Once this is achieved, any subject matter, from English to mathematics, can be imparted broadly through any type of learning style.
Chapter 2 summarizes the findings of a research project conducted by Petcoff in which she explores using emoji as a viable literacy and postsecondary writing teaching tool. Her work chronicles the teaching situation in a Texas community college, whereby an integrated reading and writing project was devised in which students attempted to demonstrate mastery of State-mandated literacy content areas using both traditional writing and the emoji code. The project provides data-driven findings that allow for the exploration of semioliteracy as a teaching approach, as well how the shared meanings of emoji by students constitute an unconscious semiotic domain. The Petcoff study offers opportunities for further research with similar groups of learning, via iconographic tracking and rendered ecologies with a particular focus on advancing literacy within the framework of first-year and postsecondary writing instructional efforts. Parallels between semioliterate qualities used in reading and writing instruction and healthcare, as well as healthcare professional education, are discussed at the conclusion of the chapter.
The historical relationship between semiotics and healthcare is explored in Chapter 3. The authors look specifically at the link between education and healthcare communications that is established by the use of emoji in such communications. The semioliterate nature of healthcare and its implications for respective education are explored, particularly as these relate to early diagnoses based on physical signs and symptoms. Parallels are then drawn between the semioliterate qualities of emoji in the Petcoff study (Chapter 2) and the potentiality of emoji as an effective doctor-to-patient healthcare communicative tool. The chapter concludes by considering how the emoji code can be inserted into traditional healthcare professional education settings, so as to show students how effective it can be in practitioner–patient interactions.
Chapter 1 offers an in-depth, historically based discussion of the research on emoji and on matters of general concern regarding this unique type of visual character, along with a rationale for the need for a comprehensive treatment of emoji in education. The authors describe the reasons for focusing on higher education, particularly health professional education. They begin by examining the background work on emoji theory and research and offer initial insights into the discourse and semiotic functions of the emoji code. Such functions form the basis for considering the emoji code as a teaching tool that may be used to craft hybrid literacy-focused instruction (textual and visual). The discursive and recursive properties of emoji form the basis of semioliteracy, a theory that one of the authors (Petcoff) contends offers a basis for emoji use in developmental reading and writing and across several higher education academic fields. Specifically, the chapter addresses the potential use of emoji as a literacy instruction tool in both higher education and healthcare professional education.
Emoji are a significant development in contemporary communication, deserving serious attention for their impact on both language use and society. Based on original mixed-methods research, this timely book focuses on emoji literacy across the healthcare landscape, with emphasis on how they are employed in healthcare worker and patient education. It situates emoji within a semioliteracy theoretical framework and presents the findings of a mixed methods study of emoji use as a literacy tool in a health professions course. Drawing on real-life case studies, it explores emoji literacy across a range of public health education contexts including doctor-to-industry, patient-to doctor, doctor-to-patient, and healthcare providers/CDC to global audience. It also advances a broader argument about the role of emoji in a paradigm shift of communication in education. This title is part of the Flip it Open Programme and may also be available Open Access.

We measure crypto and financial literacy using microdata from the Bank of Canada’s Bitcoin Omnibus Survey. Our crypto literacy measure is based on three questions covering basic aspects of Bitcoin. The financial literacy measure we use is based on three questions covering basic aspects of conventional finance (the “Big Three”). We find that a significant share of Canadian Bitcoin owners have low crypto knowledge and low financial literacy. We also find gender differences in crypto literacy among Bitcoin owners, with female owners scoring lower in Bitcoin knowledge than male owners. We do not, however, find significant gender differences in financial literacy amongst Bitcoin owners. In contrast, non-owners show gender differences in both crypto and financial literacy.
