Fay Identities of Pfaffian Type for Hyperelliptic Curves

We establish identities of Pfaffian type for the theta function associated with twice or half the period matrix of a hyperelliptic curve. They are implied by the large size asymptotic analysis of exact Pfaffian identities for expectation values of ratios of characteristic polynomials in ensembles of orthogonal or quaternionic self-dual random matrices. We show that they amount to identities for the theta function with the period matrix of a hyperelliptic curve, and in this form we reprove them by direct geometric methods.

Multi-factor thermal analysis of phase change material integrated roofing elements

In the present study, the PCM layer is integrated into the roof, analyzed, and compared for its thermal behaviour in terms of Indoor Air Temperature Reduction (IATR), Thermal Load Levelling (TLL), and Lag Time (LT) to determine the ideal position, thickness, and type of PCM. The observations from the experimental analysis were validated using COMSOL Multiphysics v6.0 with available literature. The results showed that PCM-integrated roofs reduced the interior temperature by around 30%. Furthermore, the fluctuations in the interior temperatures were reduced to 6.1% with PCM integration within the roof. A lag time of 5–8.25 h was observed for the PCM roofs. The study also found that the material properties impact the overall thermal behaviour of the PCM-integrated roofs. These properties were further explored using continuous cyclic thermal loading and variation of latent heat over a period of four days for three climatic zones in India.

(009) SEXUAL FANTASY AND DESIRE DIFFER FOR PLURISEXUAL PEOPLE IN SAME-GENDER VS. MIXED-GENDER RELATIONSHIPS

Abstract Introduction In recent years there has been a surge of research on plurisexuality (the ability to experience attraction to more than one gender). Evidence strongly suggests that plurisexual people experience desire differently, face unique stressors, and have increased risk for sexual dysfunction compared to gay and lesbian groups (Björkenstam et al., 2020). These factors may differ between plurisexual people in same-gender relationships and those in mixed-gender relationships. Fantasy and desire, two fundamental constructs of sexology theory and sex therapy, merit further research in this population. Objective We hypothesize that plurisexual people experience fantasy and desire differently depending on their relationship type (same-gender vs. mixed-gender). Methods Data was collected for a larger study of sexual health and behaviors in undergraduate students at a large university in the Midwestern US. The sample included participants in relationships (n=493; mean age = 20.48 years; 80% women, 16% men, 4% gender minority; 78% White). Respondents who identified as “bisexual,” “pansexual,” “mostly heterosexual,” “mostly lesbian/gay,” or a combination of these were coded as plurisexual, and other respondents (e.g., “heterosexual,” “lesbian/gay,” “asexual”) were coded as not plurisexual. Respondents were coded as being in same-gender relationships if they identified as a man dating a man, a woman dating a woman, or any gender minority (e.g., “non-binary,” “gender fluid”) dating a man, woman, or other gender minority person (i.e., relationships likely to be perceived as queer). Respondents were coded as being in mixed-gender relationships if they identified as a man dating a woman or a woman dating a man. Fantasy was measured with an adapted Sex Fantasy Questionnaire (SFQ; Wilson, 1988), and desire with the Sexual Desire Inventory-2 (Spector, Carey, & Steinberg, 1996). We conducted two-way ANOVAs to evaluate the influence of plurisexual identity and relationship type on fantasy and desire. Results There was a significant main effect of plurisexual identity on sexual fantasy (F(1, 391)=58.61, p<0.01) and desire (F(1, 469)=7.26 p<0.01), with plurisexual participants reporting higher levels of both. There was also a significant interaction effect between plurisexual identity and relationship type for fantasy (F(1, 391)=4.73, p=0.03) and sexual desire (F(1, 469)=5.78, p=0.02), such that the effect of plurisexuality was amplified for participants in mixed-gender relationships and attenuated for participants in same-gender relationships (see Figures). Conclusions Results suggest that plurisexual people experience higher levels of fantasy and desire when in mixed-gender vs. same-gender relationships. These differences could be attributed to perceptions that plurisexual people in same-gender relationships are queer and those in mixed-gender relationships are straight (Arriaga & Parent, 2019). Additionally, the fluidity of sexual identity suggests that experiences of attraction, desire, and fantasy change substantially based on the gender of one’s partner (Diamond, 2008). Clinically, our findings point to different applications of interventions on fantasy intended to stimulate desire in plurisexual patients with low desire, address desire discrepancy between partners, or separate problematic desire from behavior. As most research surrounding fantasy and its role in desire was developed in straight cisgender samples, clinicians and researchers should consider sexual orientation, relationship type, and their interaction when intervening upon fantasy.

Identities without Products: When the Preference for Self-Linked Products Weakens

Abstract Extant literature and common marketing practices converge around the idea that stronger self-links to a brand and its products lead to increased brand loyalty. In this article, we challenge this conventional notion by revealing situations where the preference for self-linked brands diminishes, despite the self-links remaining unchanged. We introduce a key distinction between two types of consumer identities based on whether identity expression relies on specific products: product-dependent (e.g., chef) and product-independent (e.g., foodie). Our theory posits that self-links to products exert less influence on preference when a product-independent identity is prominent. Across five studies examining consumer leisure identities, we find that priming a product-independent (vs. product-dependent) identity reduces preference for self-linked products/brands. Interestingly, it can also enhance preference for negatively self-linked (dissociative) products/brands among materialistic consumers. In a sixth experiment and a real-world Facebook study, we illustrate that the extent to which consumers’ identity is chronically product-independent can be assessed either directly or indirectly from social media interests, allowing for more effective targeting of brand-switching appeals. Adding to the literature on the symbolic role of products in identity expression, our research uniquely investigates the functional role of products in identity expression and its profound impact on product/brand preference.

Teacher, Professional or Both? A Mixed Method Study of the Professional Identity of Vocational Teachers and Trainers in Hungary

Purpose: Vocational educators in many countries enter teaching as a second career and authentic occupational expertise is seen as essential to good quality VET. The changing contexts of VET and the growing diversity of its learning populations also demand the development of teaching expertise. This dual professionalism is related to a unique combination of an occupational and a teacher identity, however, prior, and mainly qualitative research from a limited number of VET contexts suggests that often one side of this duality prevails. Our study aimed to explore the professional identity of vocational educators in Hungary and to identify some of the factors that might influence its formation. Methods: We applied a mixed method design, conducting a teacher survey (N=138) and semi-structured interviews (N=12). The quantitative and qualitative strands followed a parallel design, exploring the same topics but identity views and the organisational context were studied more deeply in the interviews. In the survey, we measured professional identity through a direct question about its type as well as questions about the importance of specific goals and teacher competence areas in vocational teaching. We used statistical and thematic analyses to study our quantitative and qualitative data. Results: Most vocational educators in our study identified as both a teacher and a professional, though the type of identity varied by gender and length of occupational work experience. Perceptions about the main goals in teaching revealed vocation/outcome-focused and student/education-focused goal orientations influenced by gender, qualifications and work experience, while our qualitative data also showed the impact of school culture and the wider socio-economic context. The goal orientations identified in the survey were more balanced for those with a dual identity, and they correlated with perceptions about the importance of different teacher competence areas, which were most influenced by whether or not the educator had obtained a pedagogical qualification. Conclusion: Our findings showed that although most vocational educators also in Hungary claim to have a dual identity, they often prioritise the development of occupational expertise as they believe it is what gives them credibility that is seen as essential to "good VET". Considering the significant impact we have found of teacher education and continued work in the occupation on identity views, it seems of utmost importance that policy and schools recognise and support the development of both occupational and teacher expertise, to ensure a balanced dual identity that seems best suited for vocational teaching.

Max Weber’s Verstehende Soziologie and Florian Znaniecki’s Cultural Sociology: A Discussion of Two Distinct but Related Notions

AbstractThis article compares Weber’s notion of Verstehende Soziologie with Znaniecki’s concepts of humanistic coefficient and cultural sociology. While both authors follow an interpretive perspective and agree that the specific object of sociological inquiry is social action, they diverge in their conceptions of social action and in their definition of sociology and its methods and aims. For, in contrast to Znaniecki, Weber holds that sociology aims not only to understand social action, but also to explain it. Social action, moreover, is differently defined according to whether it is oriented to the conduct of others, as with Weber, or aims to exert influence on others, as with Znaniecki. As for their respective methods of inquiry, Znaniecki proposes to reconstruct the actor’s experiences and viewpoints, while Weber advocates the formulation of generic ideal types for the purposes of describing and explaining social and historical courses of events. Finally, the study of the social order belongs to the cultural sciences, according to Znaniecki. For Weber, the social order is sociological, and follows from the prevalence of consensual action in particular communities such as the market or language communities. Otherwise, its prevalence should not be taken for granted.

SOME ASPECTS OF THE FORMATION OF A NEW BEHAVIORAL MODEL OF YOUTH IN AN ERA OF GROWING INTERNATIONAL CONTRADICTIONS

The article examines some aspects of the complex and controversial development process of the world, which increasingly affect the interests of the younger generation and determine the prospects for its future in the system of new emerging social relations. Transformations serve as an indicator of a change in society and forming a system of social relations. The author made attempts to analyze the impact of socio-political transformations, complex and contradictory international relations on the state of the youth environment and the formation of new elements of the behavioral model in it. These trends reflect the objective need to consider the special role of the identity of a new type of person and the components of behavior inherent in such a subject in the system of emerging social relations. Is the new generation able to create a stable and safe environment of human existence, adequate to complex challenges and crisis phenomena? In this regard, it is proposed to expand the scope of this very relevant topic in modern discourse.

Artificial intelligence and management education: A conceptualization of human-machine interaction

The increasing use of Advanced Natural Language Processing (ANLP) models, particularly ChatGPT-4, presents opportunities and challenges to management education and research. These models can enhance the style, creativity, and analytical power of research papers, potentially shifting human scholars' roles from creators to ‘prompters’. If machines can perform educational and research tasks more effectively the role of human educators becomes a salient question in a world in which ANLP models offer clear, coherent, and polished insights, the use of which has potentially paradoxical possibilities. From one perspective, a new type of high-quality scholarship and education characterized by strong human involvement that synergistically leverages ANLP models' analytical capabilities, enabling human scholars to probe complex phenomena and make management research truly meaningful and impactful for broader audiences, is possible. We explore these questions through an ‘ideal type’ conceptualization of the possible relations between AI and management education and research.

Ideal phenotypic characteristics and parental lines for hybrid rice breeding to cope with global dimming

The global food crisis has intensified with climate change, and hybrid rice (Oryza sativa L.) is expected to play a crucial role in ensuring world food security. This study analyzed the parental origins and variety characteristics of 930 hybrid rice varieties bred in Sichuan Province, a typical low-light region and one of the main production areas for hybrid rice, from 2002 to 2022. The results indicate that these varieties were hybridized using 329 direct female and 539 direct male parents. Notably, the female parent Peiai 64 and the male parents Yuehesimiao and Fenghuazhan demonstrated a higher probability of breeding rice varieties with high yield and good quality. An ideal panicle type should possess more grains, a lower 1000-grain weight, a higher seed setting percentage, and greater grain density. It is recommended to increase the utilization of excellent parents in Sichuan Province, such as parents with ideal panicle type to improve resistance to climate change, particularly global dimming.

Ethnic-Racial Identity and Attitude Change: Assessments of Outgroup and Diversity Attitudes among Adolescents in Sweden

Outgroup and diversity attitudes are important components of intercultural understanding and well-being. Despite the potential of ethnic-racial identity development as a means to foster positive outgroup and diversity attitudes, little is known about its effectiveness in rapidly diversifying contexts such as Sweden. This pre-registered study filled this gap by examining if adolescents taking part in an intervention focused on ethnic-racial identity exploration, the Identity Project, also reported change in outgroup and diversity attitudes, and whether migration background, education type, and ethnic-racial identity development predicted such change. Twenty-three tenth-grade classes in Sweden (N = 509; Mage = 16.28; SDage = 0.80; 66% female; 51% migration background) participated in the intervention and were assessed in four waves over a period of 26 weeks. Whereas ethnic-racial identity exploration and resolution increased for the intervention group, the adolescents reported no change in outgroup and diversity attitudes when compared to a control group. Increases in ethnic-racial identity exploration and resolution co-varied with increases in attitudes, but only at Time 3. The results do not provide support for the link between ethnic-racial identity development and positive outgroup and diversity attitudes, and challenge the notion of attitude change as a cascading effect of the Identity Project intervention in non-US sociocultural contexts. All aspects of the study were pre-registered on the Open Science Framework platform (https://osf.io/f5896).

Phenomenology of Somatization in Immigrants: An Idealtypical Approach

Introduction: Somatization in immigrants is frequent but standard studies do not differentiate between various forms of somatization. In this qualitative study, we used an idealtypical approach with the aim of phenomenologically differentiating between different forms of somatization in immigrants. Methods: The clinical description of the ideal types was based on seven levels: medical examination; description of somatization symptoms; the patients’ own interpretation of their somatic experience; concomitant psychopathological phenomena; genetic understanding; clinician’s interpretation; and course and treatment. Results: Five different ideal typologies of patients emerged: anxious hypochondriasis, somatization with cultural features playing a pathogenetic role, culturally shaped somatization (through pathoplastic effects), somatization as part of adjustment reactions due to migratory living difficulties, and somatization as post-traumatic reaction. Conclusion: These differences are useful to highlight the complex interrelationship between socioeconomic, migratory, cultural, and value factors in the construction of somatization among immigrants. Implications for research methodology, nosology, clinical management, and organization of medical facilities are also discussed.

Binomial ideals in quantum tori and quantum affine spaces

The article targets binomial ideals in quantum tori and quantum affine spaces. First, noncommutative analogs of known results for commutative (Laurent) polynomial rings are obtained, including the following: Under the assumption of an algebraically closed base field, it is proved that primitive ideals are binomial, as are radicals of binomial ideals and prime ideals minimal over binomial ideals. In the case of a quantum torus Tq, the results are strongest: In this situation, the binomial ideals are parametrized by characters on sublattices of the free abelian group whose group algebra is the center of Tq; the sublattice-character pairs corresponding to primitive ideals as well as to radicals and minimal primes of binomial ideals are determined. As for occurrences of binomial ideals in quantum algebras: It is shown that cocycle-twisted group algebras of finitely generated abelian groups are quotients of quantum tori modulo binomial ideals. Another appearance is as follows: Cocycle-twisted semigroup algebras of finitely generated commutative monoids, as well as quantum affine toric varieties, are quotients of quantum affine spaces modulo certain types of binomial ideals.

Human Brain Aging is Associated with Dysregulation of Cell-Type Epigenetic Identity.

Significant links between aging and DNA methylation are emerging from recent studies. On the one hand, DNA methylation undergoes changes with age, a process termed as epigenetic drift. On the other hand, DNA methylation serves as a readily accessible and accurate biomarker for aging. A key missing piece of information, however, is the molecular mechanisms underlying these processes, and how they are related, if any. Addressing the limitations of previous research due to the limited number of investigated CpGs and the heterogeneous nature of tissue samples, here we have examined DNA methylation of over 20 million CpGs across a broad age span in neurons and non-neuronal cells, primarily oligodendrocytes. We show that aging is a primary predictor of DNA methylation variation, surpassing the influence of factors such as sex and schizophrenia diagnosis, among others. On the genome-wide scale, epigenetic drift manifests as significant yet subtle trends that are influenced by the methylation level of individual CpGs. We reveal that CpGs that are highly differentiated between cell types are especially prone to age-associated DNA methylation alterations, leading to the divergence of epigenetic cell type identities as individuals age. On the other hand, CpGs that are included in commonly used epigenetic clocks tend to be those sites that are not highly cell type differentiated. Therefore, dysregulation of epigenetic cell-type identities and current DNA epigenetic clocks represent distinct features of age-associated DNA methylation alterations.

PARROT BORNAVIRUSES IN PSITTACINES KEPT IN CAPTIVITY IN THE STATE OF SANTA CATARINA, BRAZIL.

Parrot bornaviruses are responsible for proventricular dilatation disease (PDD) in psittacines. This study aimed to determine the occurrence and factors associated with Parrot bornaviruses infection in psittacines kept in captivity in a state in the southern region of Brazil. A cross-sectional study was carried out with 192 birds from two facilities (A and B) in 2019, using choanal, esophageal, and cloacal swabs and feathers, totaling 768 samples subjected to reverse-transcription polymerase chain reaction (RT-PCR), for the matrix (M) protein gene with a final product of 350 base pairs (bp). Genetic sequencing of three positive samples was performed by the Sanger method. In the study, the overall virus occurrence was 35.9% (69/192), with 40.4% (42/104) in Facility A and 30.7% (27/88) in Facility B. Sequencing analysis of the samples revealed the presence of Parrot bornavirus 2 (PaBV-2) in both facilities. Swab samples from the choanal (40/69), esophageal (30/69), cloacal (35/69), and feather (15/69) tested positive, facilitating the molecular diagnosis of Parrot bornaviruses. The results indicated that there is no single ideal sample type for antemortem molecular diagnosis of this virus. Simultaneously testing all four samples at the same time point yielded more diagnoses than testing any single sample among the four. Most of the 29 sampled psittacine species were native, and 46.9% of the birds (90/192) consisted of endangered species. Among the psittacines that tested positive, 88.4% (61/69) were clinically healthy, and 8.7% (6/69) exhibited clinical or behavioral signs, including behavioral changes, alterations in feathering, and changes in body score at the time of collection. This study showcases the application of minimally invasive sampling for diagnosing Parrot bornaviruses, enabling sample collection when the birds are restrained for clinical evaluation. This approach facilitates a prompt and effective antemortem diagnosis, thereby serving as an efficient screening method for parrots kept in captivity.

Career identity among children leaving out-of-home care: Implications on Self-Esteem and Self-Efficacy

ObjectiveThis study explores the career identity and self-concept (self-esteem and self-efficacy) of adolescents leaving out-of-home care and also examines how these two constructs are associated. MethodData were from the 2021 Independent Living Settlement Compulsory Education for Adolescents Leaving Residential Out-of-Home Care Survey. The sample included 220 children living across Gyeonggi Province, South Korea. We used latent profile analysis (LPA) for profile classification, ANOVA for identifying group differences on career identity and self-concept, and multiple regression analysis to predict self-esteem and self-efficacy with different types of career identity. ResultsAdolescents with moderate to high career identity accounted for 76.4% of the sample and they were more likely to have higher levels of self-esteem and self-efficacy compared to those with lower career identity. For Self-Doubt group, it seemed that children had mixed feelings of self-doubt and some confidence although they reported quite reasonable levels of career exploration and preparation. In addition, adolescents with higher scores of good mental health were more likely to have higher levels of self-esteem and self-efficacy. ConclusionsAdolescents with higher levels of career identity tend to have better self-concept, such as high self-esteem and self-efficacy. An integrated intervention approach is essential for adolescents leaving out-of-home care building confidence in themselves as well as having a clear career path.

The third part sheds some light on the levels of dialogue in public and multilateral diplomacy, explaining the ways dialogue promotion works in diplomacy. The final part presents some outcomes of dialogue in diplomacy and international politics in general. The content analysis applied in the article is based on various statements of the popes delivered in their speeches, addresses, homilies, letters, exhortations, and encyclicals.

Does Ultra-Endurance Passion Make Athletes Happy?

Sport psychology research of ultra-endurance (UE) athletes focused predominantly on their psychological characteristics, traits, and behaviors. However, their happiness and passion, as well as a unified framework for UE hobby phenomenon, were not sufficiently investigated. This study aims to: (1) identify the main contributors to happiness and passion of non-professional UE athletes; and (2) explore the possible relationships between types of sport passion, motivation, and athletic identity. During data collection, 116 non-professional UE athletes (mean age 43.66 years, SD = 8.97, 16.4% female) responded to an online questionnaire. Statistical analyses revealed that obsessive UE passion (p < 0.05) and amotivation (p < 0.05) predicted lower levels of happiness. A higher level of obsessive passion was predicted by extrinsic motivation (p < 0.005), amotivation (p < 0.05), and exclusivity identity (p < 0.001); a lower level was predicted by social identity (p < 0.05) and years in sports (p < 0.05). Weekly training hours and age correlated positively with passion strength, while amotivation was strongly negatively related to training volume. These results indicate that happiness of UE athletes depends on the type of sport passion formed and the quality of the underlying motivation: obsessive passion and amotivation seem to be the main enemies of happiness for UE athletes. This novel finding connecting passion, happiness, and motivation contributes to both a better understanding of the psychology of UE athletes and has practical implications for UE athletes, coaches, athletes' social circles, and sport psychologists. Due to known maladaptive outcomes of obsessive passion, including its negative impact on overall well-being, health, and now also on happiness, its formation in UE athletes needs to be observed and prevented. While the study shows predictors of obsessive passion and high vs. low obsessive passion, future research should investigate how harmonious passion impacts athletes' happiness, motivation, and identity. Likewise, research among the UE entourage would help to better understand the social impact of UE as a serious hobby and the formation of UE lifestyles. We also suggest our Temporal Framework for Progressive UE Engagement and Passion, which was further developed based on the results of this study, to be used and validated by sport psychologists.

Practices to Improve the Sustainability of Australian Cold Storage Facilities

With the ever-increasing threat of climate change and global warming, ways to make energy intensive buildings, such as cold storage warehouses essential for food preservation, more sustainable need to be found. Some refrigerated warehouse owners may be unaware or unsure of the benefits obtainable from implementing sustainable practices and technologies. To search for innovations that could inform the owners and managers of cold storage warehouses about how to enhance their sustainability, convergent interviewing of subject matter experts was conducted. The resulting practices and processes were organized into a hierarchy that ranged from essential to best practices that can be implemented to improve the sustainability of refrigerated warehouses. Examples of these practices and technologies include ideal refrigeration systems, racking methods, and insulation types. To encourage the use of sustainable practices and technologies, more reporting on successful or unsuccessful applications of practices and technologies needs to be communicated. Applying change diagnostic tools such as convergent interviewing enables a practical and industry focused set of outcomes to be determined that can help drive change towards more sustainable cold storage warehouses in Australia.
