Inspired to act: motivational effects of being moved by love and willpower.

ABSTRACTPeople can be moved and touched by exceptional closeness between people or by outstanding willpower. We investigated the causal effect of these feelings on motivations. We based our research on the previously identified phenomenon that feelings of being moved are stronger in unfavourable circumstances (e.g. psychological closeness after conflict, high achievement against all odds). In two studies in the US (N1 = 136) and in Germany (N2 = 161), we independently varied context (love vs. willpower) and circumstances (favourable vs. unfavourable) in short stories and assessed feelings of being moved as well as the motivation to show love and the motivation to show willpower after each story. In both contexts and consistent across the two studies, unfavourable circumstances elicited stronger motivations to show love as well as stronger motivations to show willpower. Multilevel mediation modelling revealed that these effects were mediated by feelings of being moved. This indicates that feelings of being moved enhance pro-social as well as achievement-related motivations.

The Endogenous Opioid System as a Pathway of Positive Emotions.

Pleasant emotions take a variety of forms and are a key part of the human experience. Although negative emotions have often been a focus of research, positive emotions, e.g., joy, pleasure, and love, have recently gained more attention. Each of these emotions is rich and complex in its own right. However, positive emotions appear to serve key evolutionary functions, which are mediated by complex biological substrates. This chapter summarizes key research and explores the biological underpinnings of positive emotions, with an emphasis on the roles that endogenous opioids play in the experience, expression, and development of positive emotions. The necessity of emphasizing positive emotions in research is also discussed.

The relationship between mobile phone dependence and academic burnout in Chinese college students: a moderated mediator model.

Objective: The aim of this study was to examine the correlation between the level of mobile phone dependence among college students and their experience of academic burnout. Additionally, the study sought to explore the potential mediating effect of study engagement and the moderating role of love. Methods: During October and December 2023, a cross-sectional study measuring mobile phone dependence, academic burnout, and study engagement among Chinese college students, using the UtrechtWork Engagement Scale-student (UWES-S), College Student Mobile Phone Dependence Questionnaire (CSMPDQ), and Academic Burnout Questionnaire (ABQ). To examine the hypothesis of mediating and moderating effect, SPSS PROCESS was utilized. Results: The predictive effect of mobile phone dependence on academic burnout was significant (ß = 0.410, t = 14.236, p < 0.001), and the predictive effect of mobile phone dependence on academic burnout remained significant when the mediating variable study engagement was introduced (ß = 0.308, t = 10.288, p < 0.001), mobile phone dependence had a significant predictive effect on study engagement (ß = -0.292, t = -11.639, p < 0.001), and study engagement had a significant positive predictive effect on academic burnout (ß = -0.270, t = -9.028, p < 0.001). Love significantly negatively predicted study engagement (ß = -0.564, t = -9.641, p < 0.001); and the interaction term for mobile phone dependence and love was significant (ß = -0.211, t = -3.688, p < 0.001), indicating a significant moderating effect of love between mobile phone dependence and study engagement. Conclusion: Mobile phones among college students has been found to have a direct correlation with academic burnout. It can also indirectly contribute to academic burnout by diminishing levels of academic engagement. This indirect relationship is further influenced by love. These findings can help researchers and educators better understand the underlying mechanisms between smartphone dependence and learning burnout in undergraduates.

Screening and genetic engineering of marine-derived Aspergillus terreus for high-efficient production of lovastatin.

BACKGROUND: Lovastatin has widespread applications thanks to its multiple pharmacological effects. Fermentation by filamentous fungi represents the major way of lovastatin production. However, the current lovastatin productivity by fungal fermentation is limited and needs to be improved. RESULTS: In this study, the lovastatin-producing strains of Aspergillus terreus from marine environment were screened, and their lovastatin productions were further improved by genetic engineering. Five strains of A. terreus were isolated from various marine environments. Their secondary metabolites were profiled by metabolomics analysis using Ultra Performance Liquid Chromatography-Mass spectrometry (UPLC-MS) with Global Natural Products Social Molecular Networking (GNPS), revealing that the production of secondary metabolites was variable among different strains. Remarkably, the strain of A. terreus MJ106 could principally biosynthesize the target drug lovastatin, which was confirmed by High Performance Liquid Chromatography (HPLC) and gene expression analysis. By one-factor experiment, lactose was found to be the best carbon source for A. terreus MJ106 to produce lovastatin. To improve the lovastatin titer in A. terreus MJ106, genetic engineering was applied to this strain. Firstly, a series of strong promoters was identified by transcriptomic and green fluorescent protein reporter analysis. Then, three selected strong promoters were used to overexpress the transcription factor gene lovE encoding the major transactivator for lov gene cluster expression. The results revealed that compared to A. terreus MJ106, all lovE over-expression mutants exhibited significantly more production of lovastatin and higher gene expression. One of them, LovE-b19, showed the highest lovastatin productivity at a titer of 1512 mg/L, which represents the highest production level reported in A. terreus. CONCLUSION: Our data suggested that combination of strain screen and genetic engineering represents a powerful tool for improving the productivity of fungal secondary metabolites, which could be adopted for large-scale production of lovastatin in marine-derived A. terreus.

Practice and Praxis: Psychoanalysis as an Act of Love.

The concept of praxis in psychoanalysis includes the way clinical practice embodies the values on which psychoanalysis is founded. As psychoanalysis evolved from a medical treatment to a process of open-ended psychic development, its underlying values evolved as well. Free-floating attention has many facets, shown in the variety of names given to it. From being a means to an end clinically, it became an implicit statement about the human value of the person being attended to. Clinical vignettes, contributions from philosophers, and examples from literature converge around the idea that the unreserved openness of free-floating attention amounts to an act of love. It is underpinned by the values, which are also virtues, of hope, and faith in the possibility of good; it can also be seen, in non-religious terms, as a form of prayer.

Corrigendum: Romantic love evolved by co-opting mother-infant bonding.

Refuting Six Misconceptions about Romantic Love.

Scientific research on romantic love has been relatively sparse but is becoming more prevalent, as it should. Unfortunately, several misconceptions about romantic love are becoming entrenched in the popular media and/or the scientific community, which hampers progress. Therefore, I refute six misconceptions about romantic love in this article. I explain why (1) romantic love is not necessarily dyadic, social, or interpersonal, (2) love is not an emotion, (3) romantic love does not just have positive effects, (4) romantic love is not uncontrollable, (5) there is no dedicated love brain region, neurotransmitter, or hormone, and (6) pharmacological manipulation of romantic love is not near. To increase progress in our scientific understanding of romantic love, I recommend that we study the intrapersonal aspects of romantic love including the intensity of love, that we focus our research questions and designs using a component process model of romantic love, and that we distinguish hypotheses and suggestions from empirical findings when citing previous work.

How culture shapes Chinese teacher's compassionate love.

BACKGROUND: Love could play a role in motivating teachers to help students and is closely related to students' achievement and prosocial behaviour. Though influenced by culture, teachers' love is not adequately studied. PURPOSE: This study explores how Chinese teachers' compassionate love is expressed and how situational factors such as Chinese culture and history influence or motivate teachers to perceive and express compassionate love for students. METHOD: This study adopted a qualitative approach of narrative study by describing and investigating the experience of a Chinese middle school teacher and two middle school students and their parents during COVID-19 pandemic. FINDINGS: Chinese teacher's compassionate love demonstrates some universal features in terms of emotional response, cognitive understanding and behaviour. Furthermore some Chinese culture-related features are also found: Chinese teachers behave in a caring and supporting way at the cost of sacrificing their own free time and comfort; an enduring long-term teacher-student relationship is valued; the Chinese culture encourages, sustains and motivates Chinese teacher's compassionate love. DISCUSSION: Teacher's compassionate love is a multi-dimensional concept entailing some universal traits in cognition, emotion and behaviour. The perception and enactment of teacher's love is subject to situational factors. Some measures for compassionate love could be built into teacher's education programme.

Development of the WeChat Public Account I Love Parasitology and its Preliminary Application in the Teaching of Human Parasitology.

OBJECTIVE: To better construct teaching resources, enhance real-time interaction and feedback between teachers and students in and out of class, and improve the teaching quality of parasitology, our team set up a WeChat public account I love Parasitology. METHODS: The data sources were mainly from original pictures and multimedia materials of different parasites collected and produced by our team, as well as related materials collected from traditional publications and digital media. With the instant interactive platform, course schedules and corresponding teaching contents were sent by push notifications, case-based learning was carried out, and 2-way communication between students and teachers was achieved. Teaching effectiveness was assessed using a self-evaluation questionnaire. RESULTS: A WeChat public account suitable for our daily teaching of parasitology was established. The second recursion and implementation of the learning resources allowed students to conduct in-depth reading and get unrestricted access to high-quality resources through the public account. In addition, all contents were in digital forms and made the original resources reborn, which would make up for our current and future shortage of physical teaching specimens. Moreover, the results from the questionnaire indicated that all these actions encouraged students to master theoretical knowledge, improved their abilities of case analysis and communication, and increased their knowledge of academic progress. CONCLUSION: Our WeChat public account can provide excellent learning materials for students and is a good supplement to the routine education of human parasitology.

Targeting the left DLPFC and right VLPFC in unmarried romantic relationship breakup (love trauma syndrome) with intensified electrical stimulation: A randomized, single-blind, parallel-group, sham-controlled study.

BACKGROUND: Ending a romantic relationship is one of the most painful losses an adult experience. Neuroimaging studies suggest that there is a neuropsychological link between breakup experiences and bereaved individuals, and that specific prefrontal regions are involved. The aim of this study was to determine whether enhancement of left DLPFC and right VLPFC activity with a novel intensified anodal transcranial direct current stimulation protocol reduces core symptoms of love trauma syndrome (LTS) and improves treatment-related variables. METHODS: In this randomized, sham-controlled, single-blind parallel trial, we assessed the efficacy of an intensified anodal stimulation protocol (20 min, twice-daily sessions with 20 min intervals, 5 consecutive days) with two montages (left DLPFC vs right VLPFC) to reduce love trauma symptoms. 36 participants with love trauma syndrome were randomized in three tDCS condition (left DLPFC, right VLPFC, sham stimulation). LTS symptoms, treatment-related outcome variables (depressive state, anxiety, emotion regulation, positive and negative affect), and cognitive functions were assessed before, right after, and one month after intervention. RESULTS: Both DLPFC and VLPFC protocols significantly reduced LTS symptoms, and improved depressive state and anxiety after the intervention, as compared to the sham group. The improving effect of the DLPFC protocol on love trauma syndrome was significantly larger than that of the VLPFC protocol. For emotion regulation and positive and negative affect, improved regulation of emotions and positive affect and reduced negative affect were revealed after intervention in the two real stimulation conditions compared to the sham. For cognitive functions, no significant difference was observed between the groups, but again a positive effect of intervention within groups in the real stimulation conditions (DLPFC and VLPFC) was found for most components of the cognitive tasks. CONCLUSIONS: Enhancement of left DLPFC and right VLPFC activity with intensified stimulation improves LTS symptoms and treatment-related variables. For LTS symptoms, DLPFC stimulation was more efficient than VLPFC stimulation., For the other variables, no significant difference was observed between these two stimulation groups. These promising results require replication in larger trials.

FEM Modeling Strategies: Application to Mechanical and Dielectric Sensitivities of Love Wave Devices in Liquid Medium.

This paper presents an extended work on the Finite Element Method (FEM) simulation of Love Wave (LW) sensors in a liquid medium. Two models are proposed to simulate the multiphysical response of the sensor. Both are extensively described in terms of principle, composition and behavior, making their applications easily reproducible by the sensor community. The first model is a Representative Volume Element (RVE) simulating the transducer and the second focuses on the sensor's longitudinal (OXZ) cut which simulates the multiphysical responses of the device. Sensitivity of the LW device to variations in the rheological and dielectric properties of liquids is estimated and then compared to a large set of measurements issued from LW sensors presenting different technological characteristics. This integral approach allows for a deeper insight into the multiphysical behavior of the LW sensor. This article also explores the advantages and drawbacks of each model. Both are in good accordance with the measurements and could be used for various applications, for which a non-exhaustive list is proposed in the conclusion.

Human love: Physical and mental health from Avicenna's viewpoint.

Avicenna is one of the most eminent and influential Persian philosophers and scientists whose philosophical and medical works are of high significance all over the world. Using descriptive analysis, the present study aims to deal with philosophical, physiological, and psychological aspects of human love and lovesickness from his perspective. His anthropology stems from his philosophical contemplation and practical experience in medicine. According to the research results, Avicenna believes that the love of noble-minded and young for external beauty, as a branch of human love, leads to the perfection of moral virtues and spiritual tendencies. Virtual love for beautiful human forms, as a representation of divine names and attributes, is a means to reach absolute perfection and true love in the mystic journey. With respect to the medical and psychological aspects, Avicenna holds that lovesickness brings disease to the soul and body of a lover. Lustful and impious love has resulted from intermingling, recurrent, and obsessive perceptions of mental forms. Since it terminates proper and moderate reasoning and disturbs the mental balance of a lover, it would lead to spiritual, mental, and even physical impairment. After explaining the features and symptoms of lovesickness, Avicenna reviews its therapeutic treatments including spiritual and physical remedies. He concludes that physical condition and temperamental health are obedient to and under the control of the mind.

Emophilia: psychometric properties of the emotional promiscuity scale and its association with personality traits, unfaithfulness, and romantic relationships in a Scandinavian sample.

Emophilia is a suggested stable phenomenon referring to how often and easily an individual falls in love (Jones, 2011). The current study investigated the psychometric properties of the Emotional Promiscuity Scale (EPS, i.e., a measure of emophilia) and its association with personality traits, romantic relationships, and unfaithfulness in a Scandinavian sample. The sample consisted of 2,607 participants, who were recruited through Norwegian and Swedish newspapers. Descriptive analyses of the EPS and a confirmatory factor analysis (CFA) to verify the previously obtained two-factor structure were conducted. Correlations between emophilia and the Big Five and Dark Triad traits were calculated to investigate the discriminative validity of the EPS. Lastly, negative binomial regression analyses were run in which emophilia comprised the independent variable and the number of romantic relationships and number of times being unfaithful constituted the dependent variables. The EPS had satisfactory internal reliability and the responses to the items were normally distributed. The CFA indicated a two-factor structure, although the two factors correlated highly, justifying collapsing them into one dimension. Emophilia showed satisfactory discriminant validity (r < 00.40) against the personality traits included. Lastly, emophilia was positively associated with the number of romantic relationships and times being unfaithful. Future research should aim to improve our understanding of the psychological and behavioral aspects of emophilia.

Love and hate do not modulate the attentional blink but improve overall performance.

How may feelings of love and hate impact people's attention? We used a modified Attentional Blink (AB) task in which 300 participants were asked to categorise a name representing a person towards whom they felt either hate, love, or neutral (first target) plus identify a number word (second target), both embedded in a rapidly presented stream of other words. The lag to the second target was systematically varied. Contrary to our hypothesis, results revealed that both hated and loved names resulted in higher accuracy for the second target than neutral names, which was largely independent of lag. Also, there we observed no sustained transfer effects of love and hate onto neutral name trials. The findings differ from prior research on attentional blink and transient, non-personal, stimulus-driven emotions, suggesting that interpersonal feelings activate different attention-relevant mechanisms. Relevant to future research, we speculate that love and hate are motivators of goal-directed behaviour that facilitate subsequent information processing.

Trait emotional intelligence and ecological outcomes: the role of connectedness to nature.

BACKGROUND: Global climate change is recognized as a major and irreversible challenge for humanity, requiring people's responsible and sustainable behaviors toward the environment. So far, the literature has widely investigated the role of cognitive determinants of ecological outcomes (e.g., pro-environmental behaviors and climate change perception), while less attention has been devoted to emotional processes, such as trait emotional intelligence (TEI). The current double study investigates whether TEI is directly and indirectly associated with climate change perception (CCP, Study 1) and pro-environmental behaviors (PEBs, Study 2) among young adults. Furthermore, the mediating role of connectedness to nature (CN), both as cognitive and emotional factors, was also analyzed. We hypothesized that CN (i.e., cognitive mediator) would positively mediate the relationship between TEI and CCP (H1), and Love and Care for Nature (LCN, i.e., emotional mediator) would positively mediate the relationship between TEI and PEBs (H2). METHODS: The study involved 342 young adults (F = 60.7%; age 19-40; Mage=22.99; SD = 2.66) in Study 1 and 365 young adults (F = 71.2%; age 17-35; Mage=22.2; SD = 3.98) in Study 2. Data were collected through an online tool shared by the snowball method. We administered the following self-reports: Trait Emotional Intelligence Questionnaire- Short Form (TEIQue- SF), Global Climate Change (GCC), and Connectedness to Nature Scale (CNS) (Study 1); Trait Emotional Intelligence Questionnaire- Short Form (TEIQue-SF), General Environmental Behaviors Scale (GEB), and Love and Care for Nature (LCN) (Study 2). RESULTS: Findings from Study 1 showed that higher TEI levels enhance CN (i.e., cognitive mediator), positively influencing CCP (estimate = 0.14; 95% CI = 0.07 to 0.23). Findings from Study 2 showed that higher TEI levels are associated with higher LCN levels (i.e., emotional mediator), influencing people's engagement in PEBs (estimate = 0.7; 95% CI = 0.03 to 0.11). CONCLUSION: It is crucial to design environmental education programs that promote greater emotional intelligence ability and encourage individuals' involvement in ecological outcomes.

Servant leadership, brand love, and work ethic: important predictors of general health in workers in the education sector.

Background: Building a path aimed at the wellbeing of workers in the education sector is the fundamental basis to encourage quality education. To fill the gap in knowledge and address this aspect by understanding the behavior of the study population, it was proposed as with the objective of determining if servant leadership, brand love and work ethic predict the general health in workers. Methods: A non-probability sampling was applied for convenience. For this purpose, a sample of 509 workers from Peru was submitted to study, who completed a questionnaire consisting of: scale of servant leadership, work ethic, GHQ-12 and brand love. By applying a quantitative method using a structural equation modeling partial least squares approach. Results: The present study demonstrated that the three constructs (servant leadership, brand love, and work ethic) predict the general health of workers in a positive and significant way, in a sample of Peruvian workers in the education sector. Furthermore, the results suggest that these factors can be used to improve the health of employees in educational institutions in Peru and possibly in other contexts as well. Conclusion: Given these results and after knowing the solidity of the predictions, the importance of promoting general health in workers in the education sector.

Adult Maltese Women's Understanding of How Childhood Domestic Violence Has Impacted Their Relationships with Their Parents and Siblings: A Grounded Theory Study.

Most of the literature that has looked at children's relationships with their parents in the domestic violence context has focused solely on the children's relationship with one parent or is studied from the perspective of one parent, usually the mother. Sibling relationships in the same context are also under-studied. This paper explores in more detail the complexity of children's relationships with their mothers, fathers, and siblings over time from the perspective of adult women and survivors of childhood domestic violence. Methods: A grounded theory methodology was used to analyse the interviews with 15 women aged twenty to forty-three years of age living in Malta. Results: the analysis showed that the domestic violence context remains significant in these important relationships for these women. The relationship with the father remains strongly influenced by the dynamics of fear, love, and retaliation, with cycles of cut-off and connection from the adult daughter's end. The relationship with the mother is complicated-feelings of love that are seen as having been limited and complicated by betrayal if there was abuse from the mother. Similarly, for the siblings, the roles of the early family of origin remain persistent and significant. However, in some of these relationships, there has been transformation, reconciliation, and forgiveness. The article offers implications for therapeutic practice for dealing with the complexity of these relationships and ideas for future research.

Surface Acoustic Wave Resonator Chip Setup for the Elimination of Interfering Conductivity Responses.

A surface acoustic wave (SAW) resonator chip setup is presented that eliminates interfering signal responses caused by changes in the electrical environment of the surrounding media. When using a two-port resonator, applying electrically shielding layers between the interdigital transducers (IDTs) can be challenging due to the limited dimensions. Therefore, a layered setup consisting of an insulating polymer layer and a conductive gold layer was preferred. The SAW resonators were provided with polycarbonate housings, resulting in SAW resonator chips. This setup enables easy application of a wide range of coatings to the active part of the resonator surface, while ensuring subsequent electrical and fluidic integration of the resonator chips into a microfluidic array for measurements. The signal responses of uncoated SAW resonators and those with polymer coatings with and without a gold layer were tested with aqueous potassium chloride (KCl) solutions up to 3 mol/L, corresponding to conductivities up to 308 mS/cm. The use of a polymer coating at the thickness of the first Love mode resonance and a conductive gold layer completely reduced the electrical impact on the SAW resonator signal response, making small signals resulting from changes in viscosity and density of the KCl solutions visible.

Feeling loved in mixed-gender adolescent romantic relationships in the face of daily stress and support: A dyadic diary study.

A profound developmental experience is the emergence of adolescent romantic relationships and first feelings of love. However, the daily nature of feeling loved in adolescents' everyday lives is poorly understood. We investigated how daily stress severity was associated with adolescents' levels of feeling loved and whether romantic partner support moderated these associations. Furthermore, we investigated this for non-interpersonal and interpersonal stressors. N = 97 mixed-gender adolescent romantic couples (age M = 16.38, SD = 1.02) from an ethnically diverse sample (42.2% Hispanic/Latino/a/x, 44.7% White) participated in dyadic diary assessments twice a week for 12 consecutive weeks. Both partners independently completed open-ended questions about a daily stressor, indicating stress severity, perceived partner support, and feeling loved. Daily stressors were coded for non-interpersonal and various types of interpersonal stressors. Results from the dyadic multilevel model showed that days with lower than average support from a romantic partner amplify the adverse effects of stress severity on feeling loved, especially when the partner is involved in the stressor. We discuss the spillover of stress in romantic relationships and the stress-buffering functions of adolescent romantic partner support. Adolescent romantic partners are potentially essential regulators of stress, increasing adolescents' feelings of love. RESEARCH HIGHLIGHTS: Romantic love is central in adolescents' lives; we showed that adolescents generally feel loved by romantic partners. Feeling loved fluctuates daily as adolescents feel less loved on stressful days. However, when adolescents perceive their partner as supportive, there is no association between stress and feeling loved. Partner support is protective for feeling loved. The current study provides essential insights into when adolescents and why adolescents feel loved.

Reciprocal self-disclosure makes children feel more loved by their parents in the moment: A proof-of-concept experiment.

Feeling loved by one's parents is critical for children's health and well-being. How can such feelings be fostered? A vital feature of loving interactions is reciprocal self-disclosure, where individuals disclose intimate information about themselves. In a proof-of-concept experiment, we examined whether encouraging reciprocal self-disclosure in parent-child dyads would make children feel more loved during the conversation. Participants were 218 children (ages 8-13, 50% girls, 94% Dutch) and one of their parents (ages 28-56, 62% women, 90% Dutch). Parent-child dyads received a list of 14 questions and took turns asking them each other for 9 min. Dyads were assigned randomly to engage in self-disclosure (questions invoking escalated intimacy) or small talk (questions invoking minimal intimacy). Before and after, children reported how loved they felt by their parent during the conversation. Self-disclosure made children feel more loved during the conversation than did small talk. Compared to small talk, self-disclosure did not instigate conversations that were lengthier or more positive; rather, it instigated conversations that were more emotionally charged (reflecting anger, anxiety, and sadness), social (discussing family and friends), reflective (creating insight), and meaningful (addressing deeply personal topics, including the passing of loved ones). The dyad's gender composition did not significantly moderate these effects. Our research suggests that reciprocal self-disclosure can make children feel more loved in the moment, uncovers linguistic signatures of reciprocal self-disclosure, and offers developmental scientists a tool to examine causal effects of reciprocal self-disclosure in parent-child dyads. Future work should examine long-term effects in everyday parent-child interactions. RESEARCH HIGHLIGHTS: How can parents make children feel more loved by them in the moment? We theorize that these feelings can be cultivated through reciprocal self-disclosure. In a proof-of-concept experiment, we examined effects of reciprocal self-disclosure versus small talk in 218 parent-child dyads, with children aged 8-13. Self-disclosure (vs. small talk) made children feel more loved during the conversation. Linguistically, self-disclosure instigated conversations that were more emotionally charged, social, reflective, and meaningful. This research provides an experimental method to study self-disclosure in parent-child dyads and suggests that self-disclosure can make children feel more loved in the moment.
