Symmetric Reverse n-Derivations on Ideals of Semiprime Rings

This paper focuses on examining a new type of n-additive map called the symmetric reverse n-derivation. As implied by its name, it combines the ideas of n-additive maps and reverse derivations, with a 1-reverse derivation being the ordinary reverse derivation. We explore several findings that expand our knowledge of these maps, particularly their presence in semiprime rings and the way rings respond to specific functional identities involving elements of ideals. Also, we provide examples to help clarify the concept of symmetric reverse n-derivations. This study aims to deepen our understanding of these symmetric maps and their properties within mathematical structures.

Antibody sequence determinants of viral antigen specificity.

Throughout life, humans experience repeated exposure to viral antigens through infection and vaccination, resulting in the generation of diverse, antigen-specific antibody repertoires. A paramount feature of antibodies that enables their critical contributions in counteracting recurrent and novel pathogens, and consequently fostering their utility as valuable targets for therapeutic and vaccine development, is the exquisite specificity displayed against their target antigens. Yet, there is still limited understanding of the determinants of antibody-antigen specificity, particularly as a function of antibody sequence. In recent years, experimental characterization of antibody repertoires has led to novel insights into fundamental properties of antibody sequences but has been largely decoupled from at-scale antigen specificity analysis. Here, using the LIBRA-seq technology, we generated a large data set mapping antibody sequence to antigen specificity for thousands of B cells, by screening the repertoires of a set of healthy individuals against 20 viral antigens representing diverse pathogens of biomedical significance. Analysis uncovered virus-specific patterns in variable gene usage, gene pairing, somatic hypermutation, as well as the presence of convergent antiviral signatures across multiple individuals, including the presence of public antibody clonotypes. Notably, our results showed that, for B-cell receptors originating from different individuals but leveraging an identical combination of heavy and light chain variable genes, there is a specific CDRH3 identity threshold above which B cells appear to exclusively share the same antigen specificity. This finding provides a quantifiable measure of the relationship between antibody sequence and antigen specificity and further defines experimentally grounded criteria for defining public antibody clonality.IMPORTANCEThe B-cell compartment of the humoral immune system plays a critical role in the generation of antibodies upon new and repeated pathogen exposure. This study provides an unprecedented level of detail on the molecular characteristics of antibody repertoires that are specific to each of the different target pathogens studied here and provides empirical evidence in support of a 70% CDRH3 amino acid identity threshold in pairs of B cells encoded by identical IGHV:IGL(K)V genes, as a means of defining public clonality and therefore predicting B-cell antigen specificity in different individuals. This is of exceptional importance when leveraging public clonality as a method to annotate B-cell receptor data otherwise lacking antigen specificity information. Understanding the fundamental rules of antibody-antigen interactions can lead to transformative new approaches for the development of antibody therapeutics and vaccines against current and emerging viruses.

The Influence of R&D Intensity on Supply Chain Transparency: Evidence From the Disclosure Substitution Perspective

ABSTRACTThis paper shows that the existence of disclosure‐related costs and benefits explains the influence of R&D intensity on supply chain transparency. We find that R&D‐active firms are more likely to redact supply chain identities but disclose supply chain distribution as a substitution. The effect of withholding (disclosing) the specific identities (distribution) of supply chain is more (less) pronounced when firms are in higher competitive industries or non–state‐owned enterprises. Our study provides evidence of disclosure substitution behavior in a unified voluntary setting of supply chain transparency and shows that partial disclosure of nonproprietary information may be optimal.

Language and terminology to describe transgender communities; Perspectives from people with lived experience

Background There is no consensus over the meaning of “transgender,” “trans and gender diverse,” and other terminology used to describe people with a gender different from the gender presumed or recorded for them at birth. We aimed to survey transgender (trans) individuals to understand lived experience perspectives on terminology. Methods An online cross-sectional survey of trans people currently living in Australia and aged ≥16 was conducted from June 2021 to April 2022. Demographic data and terminology preferences were ascertained through fixed-option and free-text questions. Results Of 1023 respondents with a median age of 30 years (IQR 24, 41), 37.1% were trans women, 34.9% were trans men, 27.6% were non-binary, and 0.4% had a culturally specific identity. There was no consensus regarding community-level terminology, with “trans/transgender and gender diverse” the most preferred term (21.9%), followed by “trans/transgender” (19.3%), and “gender diverse” (15.1%). The term “trans/transgender” was more preferred by trans women (27.9%), trans men (19.0%), respondents who had a history of or wanted gender-affirming hormone therapy (GAHT; 20.7%), and gender-affirming surgery (GAS; 20.9%), compared to non-binary respondents (8.2%), and respondents who did not want GAHT (4.9%) or GAS (13.9%). Three themes emerged from free-text responses regarding term preference: (1) Inclusivity, (2) Trans as a binary and medicalized experience, and (3) Societal understanding, accessibility, and destigmatization. Conclusion From Australian trans communities’ perspectives, the term “trans/transgender and gender diverse” was the most preferred community-level terminology to collectively describe people with a gender different from the gender presumed or recorded for them at birth. Further perspectives are needed from other cohorts internationally.

Revisiting Student Stories: Understanding Microaggressions and Interpersonal Conflict Within Speech-Language and Hearing Sciences Training Programs.

The current study revisits our previous research, delving deeper into microaggressions (MAs) and interpersonal conflict (IC) in speech, language, and hearing sciences (SLHS) training programs. Participants came from both marginalized and nonmarginalized backgrounds. A 39-item electronic survey based on our previous research was distributed online to 236 participants of current and former SLHS students through social media and e-mail listservs. Students that identified as belonging to marginalized and nonmarginalized groups reported high levels of MAs and IC, respectively. Linear regression revealed that the more marginalized identities a participant reported, the more aggression they experienced. Analyses also suggest that specific cultural and linguistic identities more likely predicted experiencing specific types of MAs than others. MAs and IC were largely underreported. This study highlights the quantifiable prevalence of MAs and IC in SLHS training programs. It underscores the urgent need for targeted interventions to address systemic inequities. Overall, these findings emphasize the importance of fostering an inclusive and equitable environment in SLHS, promoting cultural competence, and social justice in the professions. https://doi.org/10.23641/asha.27105613.

The role of social identity in a suicide prevention programme for construction workers in Australia.

Each year, more than 700 000 people die by suicide globally, the majority of whom are men. The United Nations and World Health Organization have set targets to reduce suicide rates by one-third by 2030. While large-scale suicide prevention programmes are required to meet these targets, diffusion of these types of initiatives is difficult-particularly with male populations. This qualitative study investigated the MATES in Construction suicide prevention programme in Australia. Guided by Social Identity Theory and the Social Identity Model for Collective Action, the study aimed to understand why construction workers chose to volunteer and advocate for industry-based suicide prevention programmes, and how their worker identity, solidarity and relationships impacted their volunteering and advocacy. Semi-structured interviews were conducted with 28 participants who had chosen to engage with MATES as volunteers. Data were interpreted using a reflexive approach to thematic analysis, and four themes were constructed from the data relating to feelings of belonging, connection and solidarity between workers and their industry; how specific context and roles impacted identity while existing within an overall sense of identity and solidarity; how industry mateship supported engagement in suicide prevention; and how the role of lived experience, mateship and responsibility provided hope for change. Providing intervention skills to workers, particularly workers with a lived experience of mental ill-health, empowered them to believe that they could make a difference by acting collectively. The MATES engagement model described in this study may have applications for other health promotion prevention programmes targeting male cultures.

Experiences of Social Burden amongst Survivors of Breast Cancer in Gaza: A qualitative study

PurposeThis qualitative study explores how social-cultural factors can either amplify or attenuate prospects for social support following a breast cancer diagnosis. The aim is to analyse narratives of individuals diagnosed with breast cancer to examine how the illness influences social support and hence their post-illness experiences. MethodsForty semi-structured interviews, including thirty-eight with breast cancer survivors, are analysed using a grounded theory approach. Data were collected between September 2020 and April 2021. ResultsParticipants' perceptions indicate that three main factors influenced experiences and the level of social support received. The first involves stigmatised cancer-related discourses and practices affecting women's social interactions and roles. The second is specific to (ex)married participants. It reveals how the foundation of marriage prior to the illness is a determining and influencing factor in the experience of women after illness. The third demonstrates how specific social identities enable coping, negotiation, and challenging cancer-related stigma, turning their experiences toward positivity. ConclusionsThe study concludes that breast cancer acts as a figurative magnifying glass, illuminating latent social practices in the community. This highlights the need to nurture existing social bonds or address the fragility of ties within distinct social categories. Implications for Cancer SurvivorsThe research suggests implementing customised support interventions aligned with each group of survivors' unique needs. Furthermore, enhancing awareness within patients' social networks regarding the illness and how to provide support, along with enhancing survivors' financial security through economic empowerment, may contribute to more effective coping with the social consequences of the illness.

Dimensions of experienced gender and prospective self-injurious thoughts and behaviors in preadolescent children: A national study

ObjectivesGender diverse youth face higher risk of engaging in self-injurious thoughts and behaviors (SITBs) compared to cisgender youth. Limitations in past research include a focus on older adolescents, an emphasis on specific gender identity labels that may not be inclusive of the range of youth gender experiences, and reliance on cross-sectional data. Thus, the current study prospectively evaluated dimensions of experienced gender in relation to first-onset SITBs among preadolescents. MethodsData were drawn from the Adolescent Brain Cognitive Development Study, a longitudinal study of youth across the United States. Youth (n = 7909) were aged 10–11 during initial assessment, and follow-up was conducted one year later. Two dimensions of experienced gender, felt-gender incongruence (not feeling aligned with the gender associated with one's sex assigned at birth) and gender non-contentedness (feeling dissatisfaction with the gender associated with one's sex assigned at birth), were assessed. Primary outcomes included non-suicidal self-injury (NSSI), suicidal ideation (SI), and suicide attempts (SA). ResultsLogistic regressions were conducted stratified by sex assigned at birth. For youth assigned female at birth, felt-gender incongruence was prospectively associated with first-onset NSSI and SI and gender non-contentedness was prospectively associated with first-onset of NSSI. For youth assigned male at birth, gender non-contentedness was prospectively associated with first-onset SI. Diverse experienced gender did not prospectively predict SA. ConclusionsDimensions of experienced gender may be associated with subsequent first-onset SITBs among preadolescents. These findings support the need for future research on risk and protective factors that may mediate or moderate this relationship.

Flexible use of facial features supports face identity processing.

People prioritize diagnostic features in classification tasks. However, it is not clear whether this priority is fixed or is flexibly applied depending on the specific classification decision, or how feature use behavior contributes to individual differences in performance. Here we examined whether flexibility in features used in a face identification task supports face recognition ability. In Experiment 1, we show that the facial features most useful for identification vary-to a surprising degree-depending on the specific face identity comparison at hand. While the ears and eyes were the most diagnostic for face identification in general, they were the most diagnostic feature for just 22% and 14% of identity decisions, respectively. In three subsequent experiments, we find that flexibility in feature use contributes to an individual's face identity matching ability. Higher face identification accuracy was associated with being aware of (Experiments 2 and 4) and attending to (Experiments 3 and 4) the most diagnostic features for a specific facial comparison. This conferred an enhanced benefit relative to focusing on features that were diagnostic of face identity decisions in general (Experiment 4). We conclude that adaptability in information sampling supports face recognition ability and discuss theoretical and applied implications.

The Metaverse Territorial Brand: A Contemporary Concept

The “Metaverse Territorial Brand” integrates core and interconnected elements into a virtual, interactional, experiential, and immersive space known as the metaverse. This type of brand encompasses the connection with immersive territories that may or may not be digital twins of real territories. It also encompasses two interconnected physical scales: the territorial and the regional, involved in another type of emerging territorial scale, known as the metaversal scale. Therefore, the “Metaverse Territorial Brand” is a digital-immersive extension of the territorial brand of physical territories, encompassing specific geographical and cultural aspects, but directed to the metaverse environment. This brand is a symbolic digital construction, but also a multifaceted one that incorporates discursive and visual elements, articulated by the social actors of the immersive territory, aiming to create a specific and distinct identity for a space in the metaverse. When talking about social actors in the metaverse (users), we highlight that this set of actors may or may not be the same as the physical territory. It is also important to highlight that both the territorial brand directed to physical territories and the “Metaverse Territorial Brand” are formed from the power relations of a given set of social actors. Therefore, without the strategic intention of a plurality of social actors that stimulate these relationships, there is no type of territorial brand involved.

Evaluating the Influence of Role-Playing Prompts on ChatGPT's Misinformation Detection Accuracy: Quantitative Study.

During the COVID-19 pandemic, the rapid spread of misinformation on social media created significant public health challenges. Large language models (LLMs), pretrained on extensive textual data, have shown potential in detecting misinformation, but their performance can be influenced by factors such as prompt engineering (ie, modifying LLM requests to assess changes in output). One form of prompt engineering is role-playing, where, upon request, OpenAI's ChatGPT imitates specific social roles or identities. This research examines how ChatGPT's accuracy in detecting COVID-19-related misinformation is affected when it is assigned social identities in the request prompt. Understanding how LLMs respond to different identity cues can inform messaging campaigns, ensuring effective use in public health communications. This study investigates the impact of role-playing prompts on ChatGPT's accuracy in detecting misinformation. This study also assesses differences in performance when misinformation is explicitly stated versus implied, based on contextual knowledge, and examines the reasoning given by ChatGPT for classification decisions. Overall, 36 real-world tweets about COVID-19 collected in September 2021 were categorized into misinformation, sentiment (opinions aligned vs unaligned with public health guidelines), corrections, and neutral reporting. ChatGPT was tested with prompts incorporating different combinations of multiple social identities (ie, political beliefs, education levels, locality, religiosity, and personality traits), resulting in 51,840 runs. Two control conditions were used to compare results: prompts with no identities and those including only political identity. The findings reveal that including social identities in prompts reduces average detection accuracy, with a notable drop from 68.1% (SD 41.2%; no identities) to 29.3% (SD 31.6%; all identities included). Prompts with only political identity resulted in the lowest accuracy (19.2%, SD 29.2%). ChatGPT was also able to distinguish between sentiments expressing opinions not aligned with public health guidelines from misinformation making declarative statements. There were no consistent differences in performance between explicit and implicit misinformation requiring contextual knowledge. While the findings show that the inclusion of identities decreased detection accuracy, it remains uncertain whether ChatGPT adopts views aligned with social identities: when assigned a conservative identity, ChatGPT identified misinformation with nearly the same accuracy as it did when assigned a liberal identity. While political identity was mentioned most frequently in ChatGPT's explanations for its classification decisions, the rationales for classifications were inconsistent across study conditions, and contradictory explanations were provided in some instances. These results indicate that ChatGPT's ability to classify misinformation is negatively impacted when role-playing social identities, highlighting the complexity of integrating human biases and perspectives in LLMs. This points to the need for human oversight in the use of LLMs for misinformation detection. Further research is needed to understand how LLMs weigh social identities in prompt-based tasks and explore their application in different cultural contexts.

Factors to Male-Female Sex Approaches and the Identification of Volatiles and Compounds from the Terminalia of Proholopterus chilensis (Blanchard) (Coleoptera: Cerambycidae) Females in Nothofagus obliqua (Mirb.) Oerst. (Nothofagaceae) Forests in Chile.

During the spring-summer seasons between 2019 and 2023, in the localities of Maquehue (La Araucanía Region) and Llifén (Los Ríos Region), we collected 262 virgin Proholopterus chilensis (1 female/2.3 males) specimens emerging from the live trunks of N. obliqua trees, an atypical sex ratio in Cerambycidae, suggesting high male competition for females. Virgin specimens of both sexes were individually placed in panel traps in the field, capturing only males (n = 184) over the field study seasons and only in traps baited with females. This fact preliminarily suggests the P. chilensis females emit possible "volatile or airborne" pheromones (eventually being a long-range sex pheromone), something unusual in Cerambycinae, the subfamily to which it currently belongs, although the taxonomic status of the species is under debate. In Llifén and Santiago (Metropolitan Region), behavioral observations were conducted, which allowed us to define the conditions necessary for male-female encounters that were replicated when carrying out volatile captures (Head Space Dynamic = HSD) and collections of compounds from terminalias excised from females. In field trials, virgin females less than ten days old were more attractive than older ones and attracted males during the night, i.e., between 23:00 and 5:00 AM, when the ambient temperature exceeded 11.6 °C. The aeration of females under the conditions described above and subsequent analysis of extracts by GC-MS allowed the identification of compounds absent in males and the control, including two oxygenated sesquiterpenes, a nitrogenous compound (C20), and a long-chain hydrocarbon (C26). From the terminalia extracts, hentriacontane, heptacosane, and heneicosyl, heptacosyl and docosyl acetates were identified by GC-MS, and their roles are unknown in the development of short-distance sexual behaviors, but they could serve to mark a trail leading the male towards the female in the final stage of approach for courtship/mating. Thus, we proposed the hypothesis that P. chilensis females emit both a long-range and a trail-pheromone, which, if confirmed, would be a rare case in this family. The specific identity of the compounds obtained by HSD, as well as the activities of these chemicals and those obtained from the terminalias, should be evaluated in future behavioral studies, as well as regarding their potential to attract males under field conditions. The current document is the first report on volatiles obtained from aerations and compounds extracted from female terminalia in P. chilensis.

The Chinese Freedom Schools: Historicizing and intersecting Lau with Brown

AbstractThe Chinese of Chinatown, San Francisco largely opposed the city-wide racial integration plan that would bus their children across the city beginning in 1971. Claiming that it was a violation of their language rights, a need for cultural preservation and continued autonomy from the San Francisco that had long excluded them, Chinatown instituted its own school system called the Chinese Freedom Schools. With this boycott of the public schools, the Chinese were constituted as oppositional to the aims of racial integration, searing constructions of them as being pro-White, anti-Black, and separatist. Yet, such a simplistic and binary argument omits the long history of exclusion including employment, schooling, housing, and voting discrimination as evidenced by the Chinese Exclusion Act (1882–1965), the only law to exclude a specifically named ethnolinguistic group. To historicize and understand the Chinese Freedom Schools, I analyze this phenomenon using a racial matrix where Asians have long occupied a liminal, in-between space as perpetually foreign, unassimilable, and as a suspect class. Drawing from the theories and concepts of LangCrit, raciolinguistic ideologies and Asian American studies, I examine how agents, institutions, the press, and policies imposed, assumed, or negotiated specific identities of the Chinese during the development, implementation, and dissolution of the Chinese Freedom Schools. I analyze how the Chinese were constructed as uncooperative, creating a competitive cleavage among Asians and Blacks, while dismissing the centrality of White families who largely moved out of the system, avoiding critique. Implications for language-in-education policy are proposed for Lau’s 50th anniversary.

Exploring the relationship between hybrid founder social identities and entrepreneurs’ psychological resilience

ABSTRACT This study explores the link between entrepreneurs’ hybrid founder social identity and psychological resilience, applying social identity theory and broaden-and-build theory. Psychological resilience is crucial for entrepreneurial success, given the challenging environments in which entrepreneurs operate. Yet, research on individual-level antecedents of entrepreneurs’ psychological resilience is limited. Entrepreneurs today strive to address social and ecological issues without sacrificing financial gain, making hybrid identity types—combining “opportunistic” (Darwinian) and “altruistic” (Communitarian or Missionary) elements—increasingly relevant. Analyzing survey data from 886 entrepreneurs, we find that entrepreneurs with specific hybrid identities (Darwinian-Communitarian or Darwinian-Missionary combinations) exhibit greater psychological resilience. We attribute this to their expanded ability to draw meanings and experience positive emotions from diverse sources, providing them with a broader psychological foundation to rely on in challenging times. This work enhances our understanding of entrepreneurs’ antecedents of psychological resilience and offers insights into the complexities of hybrid founder identities.

Genetic structure, selective characterization and specific molecular identity cards of high-yielding Houdan chickens based on genome-wide SNP

The high-yielding Houdan chicken (GGF) is characterized by high egg production and disease resistance. This study conducted whole genome resequencing of the GGF population and compared it to data from other breeds. Genetic diversity analysis revealed higher observed heterozygosity (Ho), Polymorphism information content (PIC), number of runs of homozygosity (ROH), and inbreeding coefficient (FROH) in GGF. Linkage disequilibrium (LD) decay was slowest in GGF, indicating intensive inbreeding and strong selection. These findings suggest a need for appropriate strategies to enhance genetic diversity conservation in this breed. Population structure analysis demonstrated that GGF was genetically distinct from both the red jungle fowl (RJF) and Chinese indigenous chicken (CIC) populations, highlighting GGF as a unique genetic resource warranting intensive protection and utilization. Selective sweep analysis identified genes under selection in GGF, primarily enriched in signaling pathways related to oocyte meiosis and progesterone-mediated oocyte maturation. Key candidate genes included: CCNE1, SKP1, CDC20, CDK2, ADCY8, RPS6KA6, PPP3CB, PDE3B, HSP90AB1, and AKT3. These findings provide a theoretical foundation for their potential application in poultry breeding. Additionally, this study combined bioinformatics analysis with PCR amplification and Sanger sequencing to identify 4 SNPs that can serve as a molecular identity card (ID) for GGF: SNP1 (Chr2: 136130976), SNP3 (Chr4:11705164), SNP4 (Chr4: 63255588), and SNP5 (Chr24: 3271008). This study provides a scientific basis for effective management and conservation of GGF genetic resources, and establishes a simple, economical, and accurate set of molecular IDs to combat the proliferation of inferior breeds and protect genetic resources.

Arabidopsis hydathodes are sites of auxin accumulation and nutrient scavenging.

Hydathodes are small organs found on the leaf margins of vascular plants which release excess xylem sap through a process called guttation. While previous studies have hinted at additional functions of hydathode in metabolite transport or auxin metabolism, experimental support is limited. We conducted comprehensive transcriptomic, metabolomic and physiological analyses of mature Arabidopsis hydathodes. This study identified 1460 genes differentially expressed in hydathodes compared to leaf blades, indicating higher expression of most genes associated with auxin metabolism, metabolite transport, stress response, DNA, RNA or microRNA processes, plant cell wall dynamics and wax metabolism. Notably, we observed differential expression of genes encoding auxin-related transcriptional regulators, biosynthetic processes, transport and vacuolar storage supported by the measured accumulation of free and conjugated auxin in hydathodes. We also showed that 78% of the total content of 52 xylem metabolites was removed from guttation fluid at hydathodes. We demonstrate that NRT2.1 and PHT1;4 transporters capture nitrate and inorganic phosphate in guttation fluid, respectively, thus limiting the loss of nutrients during this process. Our transcriptomic and metabolomic analyses unveil an organ with its specific physiological and biological identity.

An Efficient and Expressive Fully Policy-Hidden Ciphertext-Policy Attribute-Based Encryption Scheme for Satellite Service Systems

Satellite service systems transfer data from satellite providers to the big data industry, which includes data traders and data analytics companies. This system needs to provide access to numerous users whose specific identities are unknown. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) allows unidentified users with the proper attributes to decrypt data, providing fine-grained access control of data. However, traditional CP-ABE does not protect access policies. Access policies are uploaded to the cloud, stored, and downloaded in plain text, making them vulnerable to privacy breaches. When the access policy is completely hidden, users need to use their own attributes to try matching one by one, which is an inefficient process. In order to efficiently hide the access policy fully, this paper introduces a new efficient and expressive Fully Policy-Hidden Ciphertext-Policy Attribute-Based Encryption scheme (CP-ABE-FPH), which integrates the 2-way handshake O-PSI method with the ROBDD method. The integration offers advantages: (1) High efficiency and high expressiveness. The access policy using ROBDD is highly expressive but computationally intensive due to its recursive nature. This shortcoming is overcome in CP-ABE-FPH using the proposed O-PSI method, and the access policy is matched quickly and secretly. (2) High flexibility. The decryption process does not require the owner or the Key Generation Center (KGC) to be online, and system attributes can be added at any time. Security analysis shows that the access policy is fully hidden. Efficiency analysis and simulation results show that the proposed scheme is highly efficient in decryption compared with existing schemes.

National identities among minority and ‘majority’ ethnic groups: evidence from the 2021 census in England and Wales

ABSTRACT This paper employs data from the 2021 UK census to initially explore sub-state (English, Welsh) national identities among minority ethnic groups. This shows that these identities remain much more exclusive of people in minority groups than is a British identity, and that this exclusion is particularly marked with respect to English identity. The analysis then builds on this observation using similar data to examine English identification among the White British ‘majority’ in a ‘superdiverse’ city – London. Attributes which are typically shared by London boroughs in which identification as English deviates most from the national average, and multi-variable analysis which considers the ethnic structure of the borough in which an individual lives alongside other key factors (age, education, social class) suggest differences in identification between people living in boroughs that are characterised by more established and extensive ethnic diversity and those in boroughs transitioning from a previously more homogeneous (white) ethnic structure. In exploring how the articulation of a specific national identity might relate to ethnically-diverse or ‘superdiverse’ contexts, the paper uniquely contributes to recent research which calls for a stronger focus on how people who do not belong to migrant-minority groups might respond to living in such contexts.

Unsymmetric Chiral Ligands for Large Metallo‐Macrocycles: Selectivity of Orientational Self‐Sorting

AbstractNature uses various chiral and unsymmetric building blocks to form substantial and complex supramolecular assemblies. In contrast, the majority of organic ligands used in metallosupramolecular chemistry are symmetric and achiral. Here we extend the group of unsymmetric chiral bile acids used as a scaffold for organic bispyridyl ligands by employing chenodeoxycholic acid (CDCA), an epimer of the previously used ursodeoxycholic acid (UDCA). The epimerism, flexibility, and bulkiness of the ligands leads to large structural differences in coordination products upon reaction with Pd(NO3)2. The UDCA‐bispyridyl ligand self‐assembles quantitatively into a single crown‐like Pd3L6 complex, whereas the CDCA ligand provides a mixture of coordination complexes of general formula PdnL2n, i.e., Pd2L4, Pd3L6, Pd4L8, Pd5L10, and even Pd6L12 containing an impressive 120 chiral centers. The coordination products were studied by a combination of analytical methods, with ion‐mobility mass spectrometry (IM‐MS) providing valuable details on their structure and allowed an effective separation of m/z 1461 to individual signals according to the arrival time distribution, thereby revealing four different ions of [Pd3L6(NO3)3]3+, [Pd4L8(NO3)4]4+, [Pd5L10(NO3)5]5+, and [Pd6L12(NO3)6]6+. The structures of all the complexes were modelled using DFT calculations. Finally, the challenges and conclusions in determining the specific structural identity of these unsymmetric species are discussed.

Parenting Through Piil Pesenggikhi Values of Lampung Culture for Early Childhood Moral Development

This research aims to reveal how piil pesenggikhi develops and becomes a family parenting pattern for the Lampung people. Piil pesenggikhi is taught by parents from early childhood through the family environment. However, immoral behaviours are still committed by children from Lampung community families. The problem formulation presented is how parents teach their children these values for early childhood moral development. This research uses qualitative methods to examine Lampung community families and traditional Lampung elders. Researchers found a specific identity from the values of piil pesenggikhi, including nemui nyimah, juluk adok, nengah nyappor, and sakai sambayan. Through these values, early childhood moral development is carried out through learning that prioritizes respect, courtesy, hospitality, acceptance of differences, perseverance, and teaching children to help each other.
