Capillary adhesion of stick insects.

Scientific progress within the last few decades has revealed the functional morphology of an insect's sticky footpads-a compliant pad that secretes thin liquid films. However, the physico-chemical mechanisms underlying their adhesion remain elusive. Here, we explore these underlying mechanisms by simultaneously measuring adhesive force and contact geometry of the adhesive footpads of live, tethered Indian stick insects, Carausius morosus, spanning more than two orders of magnitude in body mass. We find that the adhesive force we measure is similar to the previous measurements that use a centrifuge. Our measurements afford us the opportunity to directly probe the adhesive stress in vivo and use existing theory on capillary adhesion to predict the surface tension of the secreted liquid and compare it to previous assumptions. From our predictions, we find that the surface tension required to generate the adhesive stresses we observed ranges between 0.68 and 12 mN m - 1 ${\rm m}^{-1}$ . The low surface tension of the liquid would enhance the wetting of the stick insect's footpads and promote their ability to conform to various substrates. Our insights may inform the biomimetic design of capillary-based, reversible adhesives and motivate future studies on the physico-chemical properties of the secreted liquid.

First record of Orthohalarachneattenuata in Arctocephalusaustralis in mainland Argentina (Parasitiformes, Mesostigmata, Dermanyssoidea, Halarachnidae) with observations on its ambulacral morphology.

Pinniped respiratory mites of the species Orthohalarachneattenuata have been recorded from various locations around the world but not from continental Argentina. In the present work, we document for the first time the presence of O.attenuata on Arctocephalusaustralis on the Argentine mainland. A total of 23 adult and 381 immature mites were collected from the nose and nasopharyngeal cavity during a necropsy. The mite ambulacrum is described in adults and larvae. This structure consists of a pretarsus, an extensible pulvillum, a pair of claws and paradactyli (pretarsus opercula). The ambulacral structures also have some peculiarities, such as the presence of longitudinal furrows in the claws, straight claws in legs II and III (as opposed to curved in legs I and IV), and the fin-shaped paradactyli. The morphology of the ambulacrum of this mite is interpreted as an adaptation for anchoring to different surfaces of the host, and the protective structures present in the larvae as an adaptation for the dispersal phase in the external environment.

Subjective and fitting evaluation of a revised physical attachment interface for a passive exoskeleton chair.

Passive exoskeleton chairs can alleviate fatigue, enhance efficiency, and reduce the risk of musculoskeletal diseases for workers standing for prolonged hours and have gradually been applied in recent years. In this study, by strategically distributing elastic and non-elastic fabrics, physical interfaces of the attachment system for the exoskeleton chair were revised to better adapt to bodily deformations and movements. We conducted an experiment using motion capture systems and subjective questionnaires to evaluate the performance of the initial and revised attachment systems of an exoskeleton chair worn by participants while performing multiple simulated assembly tasks. The results indicated that when wearing the revised one, some adverse effects on gait were significant reduced, as was the relative displacement of straps and discomfort in lumbar and abdominal, and system usability was improved, all of which were considered to be helpful in design to improve the performance of the attachment system in the future.

This study aims to address the limited adaptability of the physical interface of attachment system (AS) to movements and bodily deformations. We proposed a revised AS by strategically incorporating elastic and non-elastic fabrics. Our results indicate that the revised AS alleviates negative effects on gait and discomfort, and improves overall usability.

Neural correlates of distress and comfort in individuals with avoidant, anxious and secure attachment style: an fMRI study.

Despite a growing literature, experiments directly related to attachment are still needed. We explored brain processes involved in two aspects of attachment, distress and comfort. Seventy-eight healthy adult males with different attachment styles (secure, avoidant, and anxious) viewed distress, comfort, complicity-joy and neutral images (picture database BAPS-Adult) in an fMRI block design. ROIs from the modules described in the functional Neuro-Anatomical Model of Attachment (Long et al. 2020) were studied. Secure participants used more co- and self-regulation strategies and exhibited a higher activation of the reward network in distress and comfort viewing, than insecure participants. Avoidant participants showed the lower brain activations. Their approach and reward modules were the least activated in distress and comfort. Anxious participants presented both higher activations of the approach and aversion modules during complicity-joy. In addition, comfort and complicity-joy were processed differently according to attachment styles and should be differentiated among positive stimuli to disentangle attachment processes.

Emotion Regulation, Relationship and Therapeutic Change in Analytical Psychology and Contemporary Psychodynamic Approaches.

All contemporary psychotherapies agree that (failing) emotion regulation is central to psychological disorders and that psychotherapy is about improving emotion regulation. In his research on the "emotion-laden" complex Jung put an emphasis on the role of failing emotion regulation in contributing to psychological disorders as well as to change in the process of psychotherapy, but he left this field of research and took a very different direction in favour of his archetype concept. Psychodynamic approaches generally argue that changes in emotion regulation are accomplished through corrective emotional experiences in the therapeutic relationship. Insights from affective neurosciences and attachment research have had a major influence on how the therapeutic relationship is constructed in contemporary psychodynamic approaches. There is a lack of similar developments in analytical psychology, which leads to substantial differences between the models of Jungian psychotherapy in contrast to other contemporary psychodynamic approaches. The implications of these differences for the practice of psychotherapy and especially the role of the therapeutic relationship are pointed out.

Toutes les psychothérapies actuelles s'accordent sur le fait que la régulation (défaillante) de l'émotion est au centre des désordres psychologiques et que la psychothérapie vise à améliorer la régulation de l'émotion. Dans sa recherche sur le « complexe à haute charge émotionnelle ¼, Jung a mis l'accent sur le rôle de la régulation défaillante de l'émotion comme participant aux désordres psychologiques ainsi qu'au changement dans le processus de psychothérapie. Mais il a abandonné ce champ de recherche et pris une direction très différente, y préférant son concept de l'archétype. Les approches psychodynamiques plaident généralement en faveur de l'idée que les changements dans la régulation de l'émotion sont atteints par les expériences émotionnelles corrective dans la relation thérapeutique. Des apports venant des neurosciences affectives et des recherches sur l'attachement ont eu une influence majeure sur comment la relation thérapeutique est construite dans les approches psychodynamiques actuelles. De tels développements font défaut dans la psychologie analytique, ce qui conduit à des différences considérables entre les modèles de psychothérapie jungienne en contraste avec les autres approches psychodynamiques actuelles. L'article souligne les conséquences de ces différences dans la pratique de la psychothérapie, tout particulièrement en ce qui concerne le rôle de la relation thérapeutique.

Todas las psicoterapias contemporáneas coinciden en que la regulación (fallida) de las emociones es central a los trastornos psicológicos y que la psicoterapia consiste en mejorar la regulación de las emociones. En su investigación sobre el complejo "de tonalidad afectiva", Jung hizo hincapié en el rol de una fallida regulación emocional en el desarrollo de los trastornos psicológicos, así como al cambio en el proceso de psicoterapia, pero abandonó este campo de investigación y tomó una dirección muy diferente en favor de su concepto de arquetipo. En general, los enfoques Psicodinámicos sostienen que los cambios en la regulación de las emociones se logran a través de experiencias emocionales correctivas en la relación terapéutica. Los conocimientos de las neurociencias afectivas y la investigación sobre el apego han tenido una gran influencia en cómo comprender la conformación de la relación terapéutica en los abordajes psicodinámicos contemporáneos. Faltan desarrollos similares en la psicología analítica, lo que conduce a diferencias sustanciales entre los modelos de la psicoterapia Junguiana en contraste con otros enfoques psicodinámicos contemporáneos. Se señalan las implicaciones de estas diferencias para la práctica de la psicoterapia y se destaca especialmente el rol de la relación terapéutica.

Musseling through: Mytilus byssal thread production is unaffected by continuous noise.

Anthropogenic low-frequency noise (ALFN) is a rising pollutant in the world oceans. Despite the ubiquity of ALFN, its effect on marine invertebrates is still poorly understood. Here, we tested how continuous low-frequency noise (CLFN), a substantial component of ALFN, affects the byssal thread production of Mytilus, a cosmopolitan genus of mussels with high ecological and economic importance. The effects of acute CLFN exposure and predator cues on byssogenesis by Mytilus spp. were explored in both the presence and absence of predator cues. While predator effluents increased thread production, CLFN had seemingly no effect on thread counts. Further, trends suggested a synergistic effect of CLFN and predator cues. The behavioral indifference of Mytilus spp. toward CLFN could contribute to the observed prevalence of these animals in inherently disturbed habitats. This would partly explain their success in colonizing and persisting on artificial substrata rife with disturbances.

An updated meta-analysis of the relation between adult attachment style and working alliance.

Objective: Previous meta-analyses have shown that client-rated working alliance is negatively correlated with attachment anxiety and attachment avoidance. The purpose of this study is to provide an updated meta-analysis of the relation between alliance and the two dimensions of attachment insecurity. Method: Random effects models were used to examine the relation between the working alliance and attachment anxiety and the relation between the working alliance and attachment avoidance. Results: The overall relation between alliance and attachment anxiety was r = -.09 (p = .01, k = 33, I2 = 43.7%). The overall relation between alliance and attachment avoidance was r = -.13 (p < .001, k = 33, I2 = 44.7%). There was no evidence that these relations varied across study characteristics such as client race or the number of therapists in the study. Conclusion: The results support the negative relations between client-rated alliance and both dimensions of client-rated attachment insecurity. Further research is needed to identify the factors that moderate this relationship, using a more diverse sample of study characteristics and a wider range of measures.

Mother-child memory conversation and children's independent memory: the roles of maternal characteristics.

Mother-child memory conversations are a nuanced and important factor in children's memory development. The current study focuses on maternal characteristics that are related to individual differences in maternal elaborative style. It also examines the role of maternal elaborative style in children's elaborativeness in the context of reminiscing and recounting. Two hundred and nine Turkish mothers (Mage = 36.32, SD = 4.99) and their 5- to 6-year-olds (Mage in months = 66.88, SD = 4.04) (110 girls, 99 boys) participated in the current study. Results revealed that maternal individuation and balanced self-construal type predicted maternal elaborativeness, which in turn predicted child elaborativeness in reminiscing and recounting. Yet, such a relation was not observed for maternal attachment styles or sensitivity. Findings suggested the importance of maternal individuation and balanced self-construal for mothers' and children's elaborativeness in memory conversations.

Understanding the Relationship Between Attachment Orientation and Physical Activity Participation: An Exploratory Study.

BACKGROUND: Physical inactivity is recognized as a global health challenge. Attachment theory may provide insight into individual physical activity (PA) patterns, informing the development of PA interventions to promote the maintenance of behavior change. This study investigated the associations between attachment orientation and why and how individuals engage in PA. Given the association between attachment and sensory processing, this study also investigated the link between sensory processing and PA participation. METHODS: Participants (N = 141) completed an online questionnaire that included the Modified Experiences of Close Relationships Scale and the Highly Sensitive Person Scale. The relationship between attachment orientation and sensory processing patterns, and preference for PA participation were analyzed using 2-sided independent t tests. RESULTS: Attachment avoidance, attachment anxiety, and sensory sensitivity were significantly related to participants' preference for PA participation in theoretically consistent ways. Avoidantly attached individuals were less likely to participate in PA as a form of social interaction (mean = 8.57, SD = 2.87, P = .005, d = 0.48). Anxiously attached individuals were more likely to participate in PA to support weight management (mean = 37.02, SD = 11.54, P = .01, d = -0.46) or if recommended by a health professional (mean = 43.55, SD = 12.45, P = .039, d = -0.88). Sensory sensitive individuals were more likely to participate in PA alone (mean = 124.11, SD = 19.23, P = .005, d = -0.510), and more likely to prefer light-intensity forms of PA (mean = 133.29, SD = 12.67, F3,123 = 5.49, P = .001). CONCLUSIONS: Findings highlight the potential value of considering an individual's attachment orientation and sensory processing patterns in the development of PA interventions. This may help to address the challenges of PA participation, by individually tailoring interventions to participants.

Ten years' evaluation of periodontal status and its changes among Japanese older adults.

AIMS: This study aims to evaluate the periodontal status and its changes among Japanese older adults over a 10-year period. METHODS AND RESULTS: A total of 206 dentate older adults aged 70 years who completely participated in 10 years of oral examination were included. The community periodontal index (CPI) was used to assess the gingival and periodontal pocket status, while the loss of attachment (LA) scoring system was used to report the extensive LA. A higher score in CPI (Code 3 and Code 4) and more extensive attachment loss were found in a majority of participants. During follow-up evaluation, mean number of sextants with CPI code 4 remained stable, while CPI code 3 significantly decreased particularly in male participants. Whereas, sextants without attachment loss significantly decreased on average. The mean number of missing sextants significantly increased from 1.1 to 1.9, and 5.8% of subjects had all sextants excluded in the follow-up. CONCLUSION: This study indicated that majority of the older people experienced severe periodontal disease and this condition remained stable during 10-year period. Additionally, the incidence of tooth loss increased as individuals aged. Regular oral care and maintenance are highly recommended for older population.

The Quality of Interpersonal Relationships, Intrusive and Deliberate Rumination and Adjustment to the Death of a Spouse.

The aim of the presented study was to gain a better understanding of relationships between the pre-loss quality of marriage, global attachment style, rumination, the severity of complicated grief and the level of posttraumatic growth among widowed individuals. After the researchers obtained the consent of the ethics board to conduct the study, they examined widowed individuals (n = 152) using the Experiences in Close Relationships - Revised, the Dyadic Adjustment Scale, the Event Related Rumination Inventory, the Inventory of Complicated Grief, and the Posttraumatic Growth Inventory. Results show a positive relationship between attachment anxiety and complicated grief via intrusive rumination, as well as a positive relationship between attachment anxiety and posttraumatic growth via intrusive and deliberate rumination. Results also show that the greater the attachment avoidance the higher the severity of complicated grief, but only in the case of perceived low quality of the marriage. The presented research provides insight into the complex associations between the quality of interpersonal relationships, rumination and adjustment to loss among individuals who experienced the death of a spouse.

Student-teacher relational entitlement and its association with students' and teachers' characteristics.

INTRODUCTION: One's sense of entitlement-the subjective perception of what one deserves from another person-can contribute to social attitudes and behaviour in positive or negative ways, depending on the way in which one construes this subjective sense. Previous work has examined how adolescents' sense of entitlement towards their parents contributes positively or negatively to their well-being. In this study, we extend this line of research and focus on adolescents' sense of entitlement towards another important authority figure-teachers, while examining its associations with both students' and teachers' characteristics and implications for students' functioning at school. METHOD: We adapted the Adolescents' Sense of Relational Entitlement towards Parents scale to tap students' relational entitlement towards their teachers. We then examined the factor structure of the adapted scale and its associations with students' and teachers' relevant psychological measures in three samples (N = 1588). RESULTS: Findings confirmed the three-factor structure of student-teacher entitlement. Studies 2-3 also revealed that students' sense of entitlement was associated with both students' variables (e.g., psychological well-being, self-esteem, perceptions of teachers' acceptance of them and students' school engagement) and teachers' emotional difficulties. Study 3's findings indicated that students' sense of entitlement was associated with their school engagement. CONCLUSION: Students' sense of entitlement towards teachers seems to be associated with teachers' emotional makeup and attitudes towards students. In addition, this subjective sense is associated with students' school engagement. These findings suggest that there is theoretical value and practical implications for further unpacking both teachers' and students' factors associated with students' sense of entitlement and examining its association with academic functioning at school.

Natural clues to danger: attachment behavior in threatening situations.

A fundamental principle of attachment theory is that threatening situations give rise to individual differences in the extent to which people seek proximity to close others. The current research examines the way in which attachment styles predict individual differences in attachment-relevant behavior during threatening events. We tested alternative theoretical perspectives concerning the association between adult attachment (specifically, attachment avoidance) and attachment behavior in the presence of natural clues to danger by observing couples (N = 204) when they were watching horror vs. control film excerpts. Results suggest that highly avoidant people engaged in less attachment behavior across both threatening and non-threatening situations. These findings have implications for the understanding of attachment-related processes and how working models of the self and others facilitate (or inhibit) the expression of attachment behavior.

Gender, attachment, and demand/withdraw patterns in the context of moderate couple conflict in cisgender, heterosexual relationships.

A common pattern in couple relationships is demand/withdraw. Within this pattern, one partner seeks connection, change, and resolution of the issue, whereas the other seeks to end the discussion and limit closeness. We sought to further understand and update the literature by examining the relationship of gender and attachment (both self-report and narrative discourse) with demand/withdraw behaviors during moderate couple conflict. Using data from 63 cisgender, heterosexual couples, we used the actor-partner interdependence model within multilevel modeling, to explore the research questions. Findings revealed that during the woman's issue, men were more likely to withdraw. During the man's issue, preoccupied attachment in either partner was associated with more demand and women higher in attachment anxiety were more likely to demand. Demand behaviors in one partner were also associated with withdraw behaviors in the other (and vice versa). In this article, we discuss the research and clinical implications of these findings.

Is There a Relationship Between the Dietary Inflammatory Index and Clinical Attachment Loss in Patients with Periodontitis?

OBJECTIVE: The pathogenesis of periodontal diseases is partially driven by oxidative stress. However, studies on the relationship between periodontitis and the inflammatory load of diet are still insufficient. Therefore, this study aimed to examine the relationship between the diet's inflammatory load and periodontitis and clinical attachment loss (CAL). METHODS: This cross-sectional study included 119 participants diagnosed with periodontitis according to the 1999 classification. The dietary inflammatory index (DII) was calculated using three-day food consumption records and divided into quartiles (Q1, Q2, and Q3). Body mass index (BMI) was calculated as weight and height (kg/m2). Clinical attachment loss (CAL) score was determined, and the patients were grouped with those CAL scores as 7 < CAL and ≥7 CAL. RESULTS: Of the 119 patients with periodontitis, aged 46.24 ± 12.84 years, 45.3% were found to have an anti-inflammatory diet profile (n = 54). When the daily energy and nutrient intake of individuals were examined, it was found that the intake of omega-3 fatty acids (p = 0.004), black tea (p = 0.021), and green pepper (p = 0.029) was higher in those with CAL < 7 compared to those with CAL ≥ 7. There was no relationship between the patients' DII and CAL values. Daily energy, protein, fiber, vitamin A, vitamin E, folic acid, Fe, Zn, and Mg intake in patients with an anti-inflammatory diet in Q1 were higher than in Q2 and Q3 (p < 0.001). CONCLUSION: This study found no relationship between DII levels and CAL scores. However, it was observed that periodontitis patients following an anti-inflammatory diet had higher intakes of omega-3 fatty acids, vitamins A, E, and C, as well as zinc and magnesium which are nutrients known to be effective against inflammation. These patients also had CAL scores below 7. Therefore, reducing the inflammatory load of the diet may prevent the development of periodontitis, and further research in this regard would be beneficial.

Attachment and inter-individual differences in empathy, compassion, and theory of mind abilities.

Social processing, namely the ability to understand others' cognitive and affective states, is crucial for successful social interaction. It encompasses socio-affective abilities such as empathy and compassion, as well as socio-cognitive abilities such as theory of mind (ToM). This study examined the link between social processing and attachment. Our study goes beyond previous research in that social processing abilities were assessed in a single, state-of-the-art behavioral paradigm using video narratives, the EmpaToM. Attachment was captured with the Adult Attachment Interview (N = 85; 50.60% women, Mage = 25.87 ± 4.50 years) measuring participants' present-day capacity to think about and communicate attachment-relevant information about the past. Additionally, a self-report attachment questionnaire was employed (N = 158). We found that AAI-based attachment security (vs. insecurity) was associated with higher behavioral ToM abilities. Furthermore, self-reported attachment avoidance was negatively correlated with behavioral compassion abilities. Our findings provide further evidence that interview-based and self-reported attachment measures do not converge, but may rather be understood as capturing different facets of attachment that relate to different components of social processing. We conclude that individuals with secure, non-avoidant attachment show social abilities that allow them to better understand others' thoughts and generate positive, caring emotions in face of others' distress.

Attachment is differentially associated with distinct behavioral social processing abilities, that is, compassion and theory of mind.Higher attachment security in the Adult Attachment Interview (AAI) is linked to higher behavioral theory of mind abilities.Increased self-reported attachment avoidance is linked to lower behavioral compassion.

Adult attachment style, perceived social support, and post-traumatic stress among female victims of sexual assault.

The present study aimed to investigate the interplay between adult attachment style, perceived social support, and post-traumatic stress (PTS) symptoms among adult female victims of sexual assault)SA(. While prior research has established the link between insecure attachment style and PTS, the underlying mechanisms are not well understood. The potential role of perceived social support as a mediator in this relationship has been largely neglected and there is a dearth of studies investigating this mediation among victims of SA. The present study sought to address this gap in literature. Two hundred twenty-six women who have endured SA completed self-report measures of attachment style, perceived social support, and PTS, using an online survey. The results confirmed the anticipated pattern, showing a positive correlation between insecure attachment styles and PTS, as well as a negative correlation with perceived social support. A mediation analysis indicated that perceived social support may be a mechanism linking attachment styles to PTS. Following SA, insecurely attached women, especially those with avoidant attachment, have difficulties relying on and utilizing support from their environment, which may render them more susceptible to PTS. Nevertheless, the mediation was partial, indicating that attachment anxiety and attachment avoidance independently contribute to the development and maintenance of PTS.

The attachment factors and attachment receptors of human noroviruses.

Human noroviruses (HuNoVs) are the leading etiological agent causing the worldwide outbreaks of acute epidemic non-bacterial gastroenteritis. Histo-blood group antigens (HBGAs) are commonly acknowledged as cellular receptors or co-receptors for HuNoVs. However, certain genotypes of HuNoVs cannot bind with any HBGAs, suggesting potential additional co-factors and attachment receptors have not been identified yet. In addition, food items, such as oysters and lettuce, play an important role in the transmission of HuNoVs. In the past decade, a couple of attachment factors other than HBGAs have been identified and analyzed from foods and microbiomes. Attachment factors exhibit potential as inhibitors of viral binding to receptors on host cells. Therefore, it is imperative to further characterize the attachment factors for HuNoVs present in foods to effectively control the spread of HuNoVs within the food chain. This review summarizes the potential attachment factors/receptors of HuNoVs in humans, foods, and microbiome.

Father-to-infant attachment and its associated factors during COVID-19 pandemic: a cross-sectional study.

BACKGROUND: The attachment between father and infant is essential to a child's later development and well-being; yet, hardly any research has examined father-to-infant attachment during the outbreak of COVID-19. This study, therefore, aims to examine psychological, interpersonal, and health-related factors associated with father-to-infant attachment at 3-12 months postpartum during the pandemic. METHOD: An online cross-sectional study was conducted between June and December 2021. A total of 775 fathers with at least one child aged 3-12 months were recruited. Participants completed measures of depression, COVID-19-related distress, relationship satisfaction, social support and other health-related factors including COVID-19 diagnosis and hospitalisation. Data on psycho-socio-demographic, obstetric, and COVID-19-related characteristics were also collected. RESULTS: Findings demonstrated that paternal depression (ß = -.33, p < .001); relationship satisfaction (ß = .19, p < .001); COVID-19-related psychological distress (ß = -.14, p < .001) and social support (ß = .13, p < .001) had a significant effect on father-to-infant attachment. Fathers who were multiparous, had COVID-19 diagnosis, and hospitalised due to COVID-19 were more likely to report poorer father-to-infant attachment. Paternal depression was the most influential factor on father-to-infant attachment, which attenuated the strength of the relationships between marital status, prematurity, history of trauma, sleep quality, and father-to-infant attachment once included into the analyses. No significant associations between educational level, employment, socioeconomic status, delivery mode, and father-to-infant attachment were observed. CONCLUSION: These findings highlight the critical role of paternal psychological well-being in establishing healthy father-to-infant attachment and the relevance of having satisfied interpersonal relationships in promoting this early relationship particularly during crises such as COVID-19 pandemic.

Dissociative Electron Attachment Dynamics of a Promising Cancer Drug Indicates Its Radiosensitizing Potential.

2-Bromo-1-(3,3-dinitroazetidin-1-yl)ethan-1-one (RRx-001) is a hypoxic cell chemotherapeutics with already demonstrated synergism in combined chemo-radiation therapy. The interaction of the compound with secondary low-energy electrons formed in large amounts during the physico-chemical phase of the irradiation may lead to these synergistic effects. The present study focuses on the first step of RRx-001 interaction with low-energy electrons in which a transient anion is formed and fragmented. Combination of two experiments allows us to disentangle the decay of the RRx-001 anion on different timescales. Sole presence of the electron initiates rapid dissociation of NO2 and HNO2 neutrals while NO2- and Br- anions are produced both directly and via intermediate complexes. Based on our quantum chemical calculations, we propose that bidirectional intersystem crossing between π*(NO2) and σ*(C-Br) states explains the experimental spectra. The fast dynamics monitored will impact the condensed phase chemistry of the anion as well.
