Existing studies have examined unhealthy food packaging information, mainly focusing on aspects such as the content, color, and text, whilst paying less attention to the boundaries of information. This paper investigates unhealthy foods through three experiments, revealing that the presence (vs. absence) of packaging information boundaries on unhealthy foods has a negative impact on consumers\' purchasing intentions (p = 0.040) (Experiment 1). The feeling of constraint mediates this effect (β = -0.078, CI: [-0.1911, -0.0111]) (Experiment 2). Additionally, consumers with an independent self-construal exhibit reduced purchasing intentions when unhealthy food packaging information boundaries are present (vs. absent) (p < 0.001), whereas those with an interdependent self-construal show increased purchasing intentions under the same conditions (p = 0.024) (Experiment 3). This paper reveals the psychological mechanism and boundary conditions of unhealthy food packaging information boundaries affecting consumers\' purchasing intention and provides practical inspiration for government policy-making related to unhealthy food packaging.

Our actions shape our everyday experience: what we experience, how we perceive, and remember it are deeply affected by how we interact with the world. Performing an action to deliver a stimulus engages neurophysiological processes which are reflected in the modulation of sensory and pupil responses. We hypothesized that these processes shape memory encoding, parsing the experience by grouping self- and externally generated stimuli into differentiated events. Participants encoded sound sequences, in which either the first or last few sounds were self-generated and the rest externally generated. We tested recall of the sequential order of sounds that had originated from the same (within event) or different sources (across events). Memory performance was not higher for within-event sounds, suggesting that actions did not structure the memory representation. However, during encoding, we observed the expected electrophysiological response attenuation for self-generated sounds, together with increased pupil dilation triggered by actions. Moreover, at the boundary between events, physiological responses to the first sound from the new source were influenced by the direction of the source switch. Our results suggest that introducing actions creates a stronger contextual shift than removing them, even though actions do not directly contribute to memory performance. This study contributes to our understanding of how interacting with sensory input shapes experiences by exploring the relationships between action effects on sensory responses, pupil dilation, and memory encoding. Importantly, it challenges the notion of a meaningful contribution from low-level neurophysiological mechanisms associated with action execution in the modulation of the self-generation effect.

Teen dating violence (TDV) is common during adolescence and has lasting negative impacts on those who experience it. Yet, there is limited research exploring how well teens recognize unhealthy behaviors and communicate boundaries, both crucial aspects in preventing TDV. This study aimed to investigate how demographic characteristics (i.e., gender, age, sexual identity, and race/ethnicity) relate to adolescents\' abilities to recognize unhealthy relationships and willingness to communicate boundaries. Participants (N = 873) completed online surveys during school hours on demographic characteristics (e.g., gender), recognition of unhealthy relationship behaviors, communicating boundaries, and navigating breakups. We found that girls, participants who identify as a sexual minority (e.g., lesbian), and White participants demonstrated significantly higher recognition of controlling behaviors compared to boys and their heterosexual and non-White counterparts, respectively, but there was no significant difference in identifying abusive behaviors such as shouting, yelling, and insulting a partner. Older participants (i.e., ages 16-18) were significantly more likely to recognize controlling and abusive behaviors as unhealthy compared to younger participants (i.e., 13-15). Further, we found that girls and older participants were significantly more willing to communicate boundaries in relationships than boys and their younger counterparts. Our findings align with prior research emphasizing the necessity for prevention strategies that raise awareness of controlling behaviors that can escalate to more severe forms of TDV and equip adolescents with the means to establish and communicate personal boundaries.

Surrogate partner therapy is a type of treatment in which the surrogate partner (SP) works in a triadic setting with a sex therapist and a patient. At the same time, the SP acts as an intimate surrogate partner to the patient. The SP treatment includes a range of therapeutic experiences such as relaxation, intimate communication, sensual and sexual contact, and training for the acquisition of social skills. In the current study, we ask what and how SPs experience, understand, and construct boundaries in their work. We used Winnicott\'s therapeutic conceptualization of psychotherapy as a mode of playing and Goffman\'s dramaturgical role theory as the theoretical framework for our exploration. Applying a phenomenological and empathic approach, we analyzed 13 in-depth interviews with Israeli SP. It appears that SP\'s transitions from one performance to another are dramatic, in that their role requires the involvement of sexual and emotional helping relations with their patients. Moreover, SPs are obliged to have secrecy at all levels and in various relationships in their lives. We uncovered various complexities that SPs experience, such as a lack of clarity about their role, which creates challenges for building their professional and personal identity and affects their family and social relationships.

Ambiguity is often recognized as an intrinsic aspect of addressing complex sustainability challenges. Nevertheless, in the practice of transdisciplinary sustainability research, ambiguity is often an \'elephant in the room\' to be either side-stepped or reduced rather than explicitly mobilized in pursuit of solutions. These responses threaten the salience and legitimacy of sustainability science by masking the pluralism of real-world sustainability challenges and how research renders certain frames visible and invisible. Critical systems thinking (CST) emerged from the efforts of operational researchers to address theoretical and practical aspects of ambiguity. By adapting key concepts, frameworks, and lessons from CST literature and case studies, this paper aims to establish (1) an expansive conceptualization of ambiguity and (2) recommendations for operationalizing ambiguity as a valuable means of addressing sustainability challenges. We conceptualize ambiguity as an emergent feature of the simultaneous and interacting boundary processes associated with being, knowing, and intervening in complex systems, and propose Reflexive Boundary Critique (RBC) as a novel framework to help navigate these boundary processes. Our characterization of ambiguity acknowledges the boundary of a researcher\'s subjective orientation and its influence on how ambiguity is exposed and mediated in research (being), characterizes knowledge as produced through the process of making boundary judgments, generating a partial, contextual, and provisional frame (knowing), and situates a researcher as part of the complexity they seek to understand, rendering any boundary process as a form of intervention that reinforces or marginalizes certain frames and, in turn, influences action (intervening). Our recommendations for sustainability scientists to operationalize ambiguity include (1) nurturing the reflexive capacities of transdisciplinary researchers to navigate persistent ambiguity (e.g., using our proposed framework of RBC), and (2) grappling with the potential for and consequences of theoretical incommensurability and discordant pluralism. Our findings can help sustainability scientists give shape to and embrace ambiguity as a fundamental part of rigorous sustainability science.

The authors conducted liquid solution studies of antimony with selenium and sulfur in order to provide information on the thermodynamic functions of the formation of these alloys. The studies are based on the vapor pressure values of the components, comprising the double partial systems of antimony with antimony chalcogenides (Sb2Se3 and Sb2S3) and antimony chalcogenides with chalcogens (Se and S). We calculated the thermodynamic functions of mixing (graphical dependencies) and evaporation (tabular data) based on the partial vapor pressure values of components, which are represented by temperature-concentration dependencies. Based on the partial pressure values of melt components, we calculated the boundaries of liquid and vapor coexistence fields at atmospheric pressure (101.3 kPa) and in a vacuum (0.9 kPa). We established the absence of the stratification region on the Sb2S3-S diagram due to the fact that, on state diagrams, the stratification region is indicated at temperatures above 530 °C, while the boiling point of liquid sulfur at an atmospheric pressure corresponds to 429 °C. Based on the position of the field boundaries (L + V) on the state diagrams, the separation of antimony alloys with selenium and sulfur via distillation into elements at atmospheric pressure is difficult due to the high boiling points of antimony-based alloys in a vacuum: Sb2Se3-Se melts require some number of condensate re-evaporation cycles.

Purpose: The aim of this study is to understand how healthcare practitioners experience organisational boundaries and silos in day-to-day operations. Based on a multi-dimensional scale of organisational boundaries, the study examines how organisational demarcation lines enable and constrain daily work tasks in the healthcare sector.Research design: The study is based on a quantitative and qualitative analysis of survey responses from 895 healthcare practitioners in Denmark.Results: The results indicate that tendencies toward organisational silos relate to systems and hierarchies (management-staff) rather than professions and departments. Moreover, the study identifies resource scarcity as an important undercurrent in the understanding of the respondents\' perceptions of boundaries and silos.Conclusion: The study contributes to existing research by documenting the coordination and collaboration challenges linked to the multitude of demarcation lines in complex health organisations.

Symbolic boundaries shape how we see and understand both ourselves and those around us. Amid periods of crisis, these boundaries can appear more salient, sharpening distinctions between \'us\' and \'them\' and reinforcing inequalities in the social landscape. Based on 50 in-depth interviews about pandemic experiences among Canadians with disabilities and chronic health conditions, we examine how this community distinguishes between the \'deserving\' and \'undeserving\', and how emotions related to blame and resentment inform the boundaries they draw. We find that people with disabilities and chronic health conditions drew boundaries based on unequal health statuses and vulnerabilities and between those who are and are not legitimately entitled to government aid. Underlying these dimensions are a familiar set of moral tropes that respondents use to assert their own superiority and to inveigh their frustrations. Together, they play an important role in solidifying boundaries between groups, complicating public perceptions of policy responses to crisis.

OBJECTIVE: Therapeutic boundaries are limits to appropriate behaviours within a therapist-client relationship (e.g. related to accepting gifts, self-disclosures, therapist neutrality and advocacy). Therapeutic boundary considerations are fundamental in the care of refugees and asylum seekers. Research on the experiences of therapists navigating such boundaries is sparse and warrants further exploration. The aim of this qualitative systematic review was to thematically synthesise literature regarding therapists\' (psychologists, psychotherapists, counsellors) experiences of implementing flexible therapeutic boundaries with refugee and asylum seeker clients and determine how such applications have been helpful for therapeutic interventions.
METHODS: Six databases were searched. Following full-text screening, 21 papers were included in the analysis. Boundary theory underpinned the analysis.
RESULTS: Three major themes were developed: (i) Changes to Therapeutic Practice & Therapeutic Intervention, (ii) Re-Conceptualisation of Therapy as \'Clinical Political\' and Re-Conceptualisation of Therapist Identity and (iii) Careful Monitoring of Personal Boundaries-Not becoming \'Hardened\' or \'Haunted\'. Papers described how, when used in a reflective, considerate way, flexible therapeutic boundaries can strengthen the therapist-client alliance and positively impact therapeutic interventions. Many therapists acknowledged making conscious efforts to re-conceptualise therapeutic work with refugee and asylum seeker clients from advocacy standpoints. However, systemic constraints, and lack of guidance, made this difficult to navigate and contributed to therapist burn-out.
CONCLUSIONS: Boundary considerations manifested as interpersonal, structural and cultural changes to practice. These have implications for clinical practice and developing guidelines on boundary practices with refugees and asylum seekers. Future research should explore promoting therapist well-being and training needs for therapists supporting this population.

Despite a growth in knowledge translation (KT) or exchange activities, and a smaller growth in their evaluations, it remains challenging to identify evidence of efficacy. This could be due to well-documented political and logistical difficulties involved in evaluating knowledge exchange interventions. By bringing in theory from science and technology studies (STS), Borst et al1 offer a new way of thinking about this problem. Most KT evaluations draw on health research traditions; centralising comparability, efficacy, and so on. Borst et al propose focusing on the work it takes to move knowledge over boundaries between these communities, seeing relationships as interactions, not just conduits for evidence. They show how \'context\' can be understood as a mutual creation, not a static environment; and that institutions shape behaviours, rather than merely being sites or platforms for evidence mobilisation. Seeing KT as a creative, active practice opens new ways to design and evaluate KT mechanisms.
