Status of Professional Identity, Self-Directed Learning Competence, and Self-Efficacy Among Central Sterile Supply Department Nurses.

BACKGROUND Previous studies on professional identity, self-directed learning competence, and self-efficacy among central sterile supply department (CSSD) nurses are rare. We investigated the status of these 3 characteristics among CSSD nurses and offered suggestions, to provide a reference for CSSD talent development. MATERIAL AND METHODS CSSD nurses working in 45 hospitals in southwest China were invited to participate in a questionnaire survey in August 2021. The survey comprised a general information questionnaire, a self-directed learning competence rating scale, a professional identity scale, and a general self-efficacy scale. RESULTS The CSSD nurses' scores for professional identity, self-directed learning competence, and self-efficacy were 109.92±17.161, 125.77±21.316, and 26.92±6.633, respectively. For professional identity, statistically significant differences were identified (P≤0.05) for 3 factors: monthly income, reason for studying nursing, and reason for working in the CSSD. For self-directed learning competence, statistically significant differences (P≤0.05) were identified for 5 factors: age, hospital grade, type of employee, monthly income, and reason for working in the CSSD. For self-efficacy, statistically significant differences were identified (P≤0.05) for 3 factors: age, reason for studying nursing and working in the CSSD, and whether the CSSD nurses wished their children to become nurses. CONCLUSIONS The professional identity, self-directed learning competence, and self-efficacy of the CSSD nurses in this study were at the medium level. More attention should be paid to career planning of young nurses and improvement of their professional identity and self-directed learning competence.

A Latent Profile Analysis of Protean Career Attitude and Vocational Identity Status

This study aimed to examine individuals with adaptive protean career attitudes in the current era. Data were obtained from surveying 672 South Korean adults in their 30s and 40s, each with at least one year of work experience. Participants were categorized based on their protean career attitudes and vocational identity status, with subsequent exploration of their relationships with meaning in life, differentiation of self, and resilience. Data analysis involved latent profile analysis, maximum likelihood analysis, and BCH analysis. Results revealed three groups: “diffused wanderer,” “organizational adapted citizen,” and “protean career identity.” The study confirmed the influence of meaning in life and differentiation of self within these profiles, along with differences in resilience. This research offers valuable insights into the characteristics of adaptable individuals based on their “protean career identity.”

Knowing Me, Knowing You: Changes in Parental Representations Among Established Adults Going Through Progressive Identity Development

AbstractDeveloping and revising one’s identity is a lifelong task, one that influences and is influenced by close relationships in the individual’s social context. For emerging adults, different approaches to identity formation have been associated with different ways of relating to their parents; however, little is known about how identity development and views on one’s parents interact beyond the emerging adult years. In the present study, we addressed this gap by examining changes in how established adults describe and relate to internal representations of their parents as they develop from identity foreclosure to identity achievement, an identity status transition that is considered progressive and has been related to shifts in parental representations in younger samples. From a longitudinal study using the Identity Status Interview (Marcia et al., Ego identity: A handbook for psychosocial research, Springer, 1993), we selected participants coded as foreclosed at age 29 and identity achieved at age 33 (N = 18). A case study approach was used to analyze individual changes in parental representations, and a thematic analysis was conducted to identify themes across cases. The findings show that progressive identity development in established adulthood may involve making more reflective comparisons between oneself and one’s parents, describing one’s parents more as whole persons, and relating to parental influence with greater independence and agency. The results highlight the continued importance of parents for adult identity development, and that progressive identity development in established adulthood may involve increased complexity in representations of both oneself and one’s parents.

MalKinID: A Likelihood-Based Model for Identifying Malaria Parasite Genealogical Relationships Using Identity-by-Descent.

Pathogen genomics is a powerful tool for tracking infectious disease transmission. In malaria, identity-by-descent (IBD) is used to assess the genetic relatedness between parasites and has been used to study transmission and importation. In theory, IBD can be used to distinguish genealogical relationships to reconstruct transmission history or identify parasites for genotype-to-phenotype quantitative-trait-locus experiments. MalKinID (Malaria Kinship Identifier) is a new likelihood-based classification model designed to identify genealogical relationships among malaria parasites based on genome-wide IBD proportions and IBD segment distributions. MalKinID was calibrated to the genomic data from three laboratory-based genetic crosses (yielding 440 parent-child and 9060 full-sibling comparisons). MalKinID identified lab generated F1 progeny with >80% sensitivity and showed that 0.39 (95% CI 0.28, 0.49) of the second-generation progeny of a NF54 and NHP4026 cross were F1s and 0.56 (0.45, 0.67) were backcrosses of an F1 with the parental NF54 strain. In simulated outcrossed importations, MalKinID accurately reconstructs genealogy history with high precision and sensitivity, with F1-scores exceeding 0.84. However, when importation involves inbreeding, such as during serial co-transmission, the precision and sensitivity of MalKinID declined, with F1-scores of 0.76 (0.56, 0.92) and 0.23 (0.0, 0.4) for PC and FS and <0.05 for second-degree and third-degree relatives. Genealogical inference is most powered 1) when outcrossing is the norm or 2) when multi-sample comparisons based on a predefined pedigree are used. MalKinID lays the foundations for using IBD to track parasite transmission history and for separating progeny for quantitative-trait-locus experiments.

Benchmarking and Optimization of Methods for the Detection of Identity-By-Descent in High-Recombining Plasmodium falciparum Genomes.

Genomic surveillance is crucial for identifying at-risk populations for targeted malaria control and elimination. Identity-by-descent (IBD) is increasingly being used in Plasmodium population genomics to estimate genetic relatedness, effective population size (N e ), population structure, and signals of positive selection. Despite its potential, a thorough evaluation of IBD segment detection tools for species with high recombination rates, such as P. falciparum, remains absent. Here, we perform comprehensive benchmarking of IBD callers - probabilistic (hmmIBD, isoRelate), identity-by-state-based (hap-IBD, phased IBD) and others (Refined IBD) - using population genetic simulations tailored for high recombination, and IBD quality metrics at both the IBD segment level and the IBD-based downstream inference level. Our results demonstrate that low marker density per genetic unit, related to high recombination relative to mutation, significantly compromises the accuracy of detected IBD segments. In genomes with high recombination rates resembling P. falciparum, most IBD callers exhibit high false negative rates for shorter IBD segments, which can be partially mitigated through optimization of IBD caller parameters, especially those related to marker density. Notably, IBD detected with optimized parameters allows for more accurate capture of selection signals and population structure; IBD-based N e inference is very sensitive to IBD detection errors, with IBD called from hmmIBD uniquely providing less biased estimates of N e in this context. Validation with empirical data from the MalariaGEN Pf 7 database, representing different transmission settings, corroborates these findings. We conclude that context-specific evaluation and parameter optimization are essential for accurate IBD detection in high-recombining species and recommend hmmIBD for quality-sensitive analysis, such as estimation of N e in these species. Our optimization and high-level benchmarking methods not only improve IBD segment detection in high-recombining genomes but also enhance overall genomic analysis, paving the way for more accurate genomic surveillance and targeted intervention strategies for malaria.

Establishing self-concordant goals: a longitudinal study on the influence of ego identity on goal self-concordance.

Self-concordant goals are those that align closely with an individual's intrinsic interests and values, driving autonomous motivation, and resulting in higher satisfaction and goal achievement. The relevance of studying the link between ego identity and goal self-concordance lies in understanding how a well-defined ego identity can foster the pursuit of authentic and fulfilling goals. This study investigates the relationship between ego identity and goal self-concordance, focusing on how individuals' sense of identity influences their alignment with personal goals. Data were gathered through a cross-sectional analysis of 292 students and a longitudinal follow-up with 98 participants over two intervals. Results confirmed significant correlations between ego identity status and various dimensions of goal self-concordance. Notably, different ego identity statuses exhibited distinct levels of goal self-concordance, ranked from highest to lowest as follows: identity achievement, achievement-foreclosure intermediate, moratorium, foreclosure, moratorium-diffusion intermediate, and diffusion. Cross-lagged analysis revealed a causal relationship where ego identity influences goal self-concordance, providing insights into the cognitive and behavioral processes involved in goal setting. This study extends the implications of the goal self-concordance model and reveals a causal relationship between ego identity status and goal self-concordance. From a practical perspective, our findings suggest that educational and developmental interventions aimed at supporting identity development and commitment could lead to more self-concordant goal setting. Such programs could ultimately promote greater well-being and personal growth among students.

Finally coming of age? EU foreign and security policy after Ukraine

ABSTRACT The war on Ukraine is the most severe security crisis that Europe, and the European Union (EU), has faced since World War II. Contrary to what many expected, the EU responded quickly and comprehensively to the Russian invasion. How, if in any way, does the EU’s response to the war on Ukraine suggest that the EU is coming of age in the foreign and security domain? By exploring EU policies and actions across three key maturation processes, our analysis finds that the EU has become a more mature foreign policy actor, in a process that started well before the Russian full scale invasion but has escalated since then. With its broad response to the war on Ukraine, the EU has shown an increased ability to take quick decisions, provide resources and combine various instruments in response to a crisis (increased decision-making ability); it is taking on a clearer foreign policy role/identity as a principled pragmatist and crisis manager (more stable identity status); and this plays out in its relations with the US, in NATO and bilaterally (more salient and defined relations).

A dynamic identity process approach to veg*nism: Does identity status matter among meat‐reducers?

AbstractThe current study investigated meat‐reducers' (vegan, vegetarian, and flexitarian) dietary identities using an identity process approach. Drawing on identity development theories, we aimed to (i) classify meat‐reducers from the United Kingdom and United States (N = 375) based on their level of identity exploration and commitment, and (ii) examine the effect of dietary identity status on diet and group‐based behaviours. Findings demonstrated evidence for three identity clusters: achieved (high exploration and high commitment), foreclosed (lower exploration and higher commitment), and diffused (low exploration and low commitment) meat‐reducers. Vegans were more likely to display an achieved dietary identity, whereas the majority of flexitarians indicated a diffused identity. More importantly, identity status had significant effects on all outcome measures, with achieved meat‐reducers reporting greatest dietary strictness, greatest centrality and private regard, but lowest public regard, as well as most negative attitudes towards meat‐eaters and greatest activism. We discuss how investigating dietary identities with a ‘process framework’ may point to a more inclusive view of social identities among people who follow a plant‐based diet.

Temporal and spatial dynamics of Plasmodium falciparum clonal lineages in Guyana.

Plasmodium parasites, the causal agents of malaria, are eukaryotic organisms that obligately undergo sexual recombination within mosquitoes. In low transmission settings, parasites recombine with themselves, and the clonal lineage is propagated rather than broken up by outcrossing. We investigated whether stochastic/neutral factors drive the persistence and abundance of Plasmodium falciparum clonal lineages in Guyana, a country with relatively low malaria transmission, but the only setting in the Americas in which an important artemisinin resistance mutation (pfk13 C580Y) has been observed. We performed whole genome sequencing on 1,727 Plasmodium falciparum samples collected from infected patients across a five-year period (2016-2021). We characterized the relatedness between each pair of monoclonal infections (n = 1,409) through estimation of identity-by-descent (IBD) and also typed each sample for known or candidate drug resistance mutations. A total of 160 multi-isolate clones (mean IBD ≥ 0.90) were circulating in Guyana during the study period, comprising 13 highly related clusters (mean IBD ≥ 0.40). In the five-year study period, we observed a decrease in frequency of a mutation associated with artemisinin partner drug (piperaquine) resistance (pfcrt C350R) and limited co-occurence of pfcrt C350R with duplications of plasmepsin 2/3, an epistatic interaction associated with piperaquine resistance. We additionally observed 61 nonsynonymous substitutions that increased markedly in frequency over the study period as well as a novel pfk13 mutation (G718S). However, P. falciparum clonal dynamics in Guyana appear to be largely driven by stochastic factors, in contrast to other geographic regions, given that clones carrying drug resistance polymorphisms do not demonstrate enhanced persistence or higher abundance than clones carrying polymorphisms of comparable frequency that are unrelated to resistance. The use of multiple artemisinin combination therapies in Guyana may have contributed to the disappearance of the pfk13 C580Y mutation.

Relatedness of Luther Burbank’s Plum (Prunus sp.) Introductions Based on Genotyping by Sequencing

The renowned horticultural artist and plant breeder Luther Burbank worked with many species of plants. During his 50-year career, he introduced more than 800 cultivars, including more than 150 accessions of plums (Prunus spp.) in the late 1800s and early 1900s. Burbank preferred using wide, interspecific crosses to create a vast range of phenotypic variation and then artificially select from the extremes. Although a great artist, Burbank was a substandard scientist because he was derelict in pedigree note-taking. Although many of his introductions are extinct, hobbyists, enthusiasts, and international collections retain nearly a third of the economically viable cultivars he bred. For a century, many of his hybridizations remained inscrutable mysteries until modern genomic and computational tools developed their resolution and statistical power. Today, genotyping by sequencing (GBS) is a useful tool for pedigree reconstruction in the absence of reliable records. GBS can inform principal component analyses, identity by descent (IBD) kinship, and phylogenetic admixture, revealing complex relationships among taxa. In this study, whole genome sequencing was performed on 53 Prunus taxa used by Burbank in his breeding experiments in the most comprehensive genetic survey of his work to date. Exact parent–offspring relationships between this population may be impossible to discern due to years of back crossing, sibling mating, and open pollination. However, the proportion of genomic similarity among these taxa provides information on the relatedness of the genotypes in Burbank’s Prunus experiments, defining four primary lineages within his breeding population. These lineages comprised primarily P. salicina and P. simonii but also have influences from P. americana, P. cerasifera, P. domestica, and P. rivularis. The prevalence of P. simonii in Burbank’s Prunus introductions appears to have been vastly underreported, indicating that some of the seedstock founders of his breeding population could have been P. salicina × P. simonii hybrids at the inception of his career. This research has implications for pedigree reconstruction and prioritizing conservation in collections curation for future studies.

Ancient DNA speaks

Many human DNA sequences have been obtained from ancient remains dating back from several millennia. However, these have low coverage and may contain many errors; this has limited their usefulness for many analyses, in particular the search for Identical By Descent (IBD) segments that is very powerful for detection of kinship. A new method, using imputation from database data and sophisticated statistical analysis, proves able to detect IBD segments (and thus parenthood) in low-quality DNA sequences from individuals linked only by sixth degree parenthood, opening a whole new field of investigation using ancient DNA.

Identity Formation in Individuals between 16 and 25 Years Old with Borderline Personality Disorder.

Background/Objectives: Identity disruption is a key feature of borderline personality disorder (BPD), characterized by disturbances in self-image. This study aimed to use the Dimensions of Identity Development Scale (DIDS) in a population aged 16-25, to assess differences in identity status and correlations with BPD features as well as whether a correlation exists between the BPD features, the scores obtained on the DIDS and the scores of the different dimensions of this disorder. Methods: We analyzed data from 132 individuals: 44 with BPD using the Diagnostic Interview for Borderline-Revised (DIB-R). Statistical analyses included quantile regression to determine the differences in the DIDS after adjusting for confounding factors identified during group comparisons and Spearman correlation between the DIDS, the BPD features and the DIB-R. Results: Results indicated significantly lower DIDS scores in the BPD group, particularly in commitment making, exploration breadth (EB), identity with commitment (IM) and ruminative exploration (RE). After adjusting, only EB differs significantly between the two groups. All dimensions of the DIDS except for the exploration in depth (ED) are correlated with BPD features. Significant correlations could be demonstrated between cognitive dimension and ED, between the total DIDS and the number of suicide attempt (SA) and between the IM and the number of SA. Conclusions: Our clinical sample showed distinct identity formation compared to controls, with a lower EB associated with BPD. RE correlated with BPD, suggesting that the individuals engage in repetitive exploratory processes. SA was negatively associated with overall identity development and commitment, indicating impulsive behaviors in BPD intersect with identity struggles.

The association between proactive personality and interprofessional learning readiness in nursing students: The chain medication effects of perceived social support and professional identity

BackgroundInterprofessional education (IPE) has been advocated for all healthcare students, and readiness for interprofessional learning significantly influences its effectiveness. It is essential to explore the antecedent factors of readiness for interprofessional learning among nursing students to promote IPE. While a proactive personality might impact readiness for interprofessional learning, its specific role has remained unspecified. ObjectiveTo examine the mediation effects of perceived social support and professional identity on the association between proactive personality and readiness for interprofessional learning among nursing students. DesignThe study utilised a cross-sectional design. SettingsResearch was conducted at two universities and two vocational schools in Hainan Province, China. ParticipantsOn-campus nursing students were invited to participate between March and May 2023. MethodsA flyer was distributed to the participants with a QR code to scan to voluntarily complete the online survey, including the Readiness for Interprofessional Learning Scale (RIPLS), Proactive Personality Scale, Perceived Social Support Scale and Professional Identity Status Questionnaire Scale 5d. Descriptive analysis, Pearson associations and mediation analysis were conducted using SPSS software version 26.0 and PROCESS version 4.2 for SPSS. ResultsThe participants' average RIPLS score was 66.93 ± 9.28. Proactive personality (r = 0.633, p < 0.01), perceived social support (r = 0.605, p < 0.01) and professional identity (r = 0.549, p < 0.01) were all positively related to readiness for interprofessional learning. Meanwhile, the relationship between proactive personality and readiness for interprofessional learning was partly mediated by perceived social support (25.15 %), professional identity (13.35 %) and the chain effects (9.48 %) of perceived social support and professional identity. ConclusionsThe nursing students in Hainan, China demonstrated a medium level of readiness for interprofessional learning. Compound strategies that foster proactive personality, provide social support and boost positive professional identity are warranted to improve nursing students' readiness for interprofessional learning.

Analysis of genetic diversity and structure of endangered Dengchuan cattle population using a single-nucleotide polymorphism chip

This study aimed to evaluate the genetic diversity and structure within the Dengchuan cattle population and effectively protect and utilize their germplasm resources. Herein, the single-nucleotide polymorphisms (SNPs) of 100 Dengchuan cattle (46 bulls and 54 cows) were determined using the GGP Bovine 100K SNP Beadchip. The results showed that among the Dengchuan cattle, a total of 101,220 SNPs were detected, and there were 83,534 SNPs that passed quality control, of which 85.7% were polymorphic. The average genetic distance based on identity-by-state (IBS) within the conservation population of Dengchuan cattle was 0.26 ± 0.02. A total of 3,999 genome-length runs of homozygosity (ROHs) were detected in the Dengchuan cattle, with ROH lengths primarily concentrated in the range of 1–5 Mb, accounting for 87.02% of the total. The average inbreeding coefficient based on ROHs was 4.6%, within the conservation population of Dengchuan cattle, whereas it was 4.9% for bulls, and the Wright inbreeding coefficient (FIS) value was 2.4%, demonstrating a low level of inbreeding within the Dengchuan cattle population. Based on neighbor-joining tree analysis, the Dengchuan cattle could be divided into 16 families. In summary, the conservation population of Dengchuan cattle displays relatively abundant diversity and a moderate genetic relationship. Inbreeding was observed among a few individuals, but the overall inbreeding level of the population remained low. It is important to maintain this low level of inbreeding when introducing purebred bloodlines to expand the core group. This approach will ensure the long-term conservation of Dengchuan cattle germplasm resources and prevent loss of genetic diversity.

Investigation and Correlation Study on the Status of Professional Identity and Job Engagement among Early Childhood Educators in Jiangsu Province

In this study, 293 preschool teachers in Jiangsu Province were selected as subjects, and the status of their professional identity, job engagement and the relationship between the two were investigated by questionnaire measurement. The results showed that the professional identity level (M=4.46) and job engagement level (M=4.15) of preschool teachers in Jiangsu Province were higher. There were no significant differences in professional identity and job engagement among different genders, age groups, and teaching years. The professional identity of preschool teachers in Jiangsu Province has a positive predictive effect on work engagement.

COVID-19-Related Financial Hardship Is Associated With Depression and Anxiety in Substance Use Treatment Across Gender and Racial Groups.

Many individuals lost their employment during the COVID-19 pandemic and experienced financial hardship. These experiences may increase risk for co-occurring conditions, including substance use disorders (SUDs) and related symptoms of depression and anxiety. This study aimed to examine the associations between COVID-19-related financial hardship and/or job loss and co-occurring symptoms, across gender and racial groups. Respondents (N = 3493) included individuals entering SUD treatment in the United States in March-October of 2020. Results demonstrated that COVID-19-related financial hardship and unemployment in the household was associated with greater depression and anxiety severity among people in SUD treatment (p's < 0.05). Our findings highlight financial hardship and loss of employment as risk factors for co-occurring depression and anxiety. However, additive effects between marginalized identity status and COVID-19 economic hardship on co-occurring symptoms were not observed.

Genomics reveals heterogeneous Plasmodium falciparum transmission and selection signals in Zambia

BackgroundGenomic surveillance is crucial for monitoring malaria transmission and understanding parasite adaptation to interventions. Zambia lacks prior nationwide efforts in malaria genomic surveillance among African countries.MethodsWe conducted genomic surveillance of Plasmodium falciparum parasites from the 2018 Malaria Indicator Survey in Zambia, a nationally representative household survey of children under five years of age. We whole-genome sequenced and analyzed 241 P. falciparum genomes from regions with varying levels of malaria transmission across Zambia and estimated genetic metrics that are informative about transmission intensity, genetic relatedness between parasites, and selection.ResultsWe provide genomic evidence of widespread within-host polygenomic infections, regardless of epidemiological characteristics, underscoring the extensive and ongoing endemic malaria transmission in Zambia. Our analysis reveals country-level clustering of parasites from Zambia and neighboring regions, with distinct separation in West Africa. Within Zambia, identity by descent (IBD) relatedness analysis uncovers local spatial clustering and rare cases of long-distance sharing of closely related parasite pairs. Genomic regions with large shared IBD segments and strong positive selection signatures implicate genes involved in sulfadoxine-pyrimethamine and artemisinin combination therapies drug resistance, but no signature related to chloroquine resistance. Furthermore, differences in selection signatures, including drug resistance loci, are observed between eastern and western Zambian parasite populations, suggesting variable transmission intensity and ongoing drug pressure.ConclusionsOur findings enhance our understanding of nationwide P. falciparum transmission in Zambia, establishing a baseline for analyzing parasite genetic metrics as they vary over time and space. These insights highlight the urgency of strengthening malaria control programs and surveillance of antimalarial drug resistance.

Increase in Functional Tic Presentations in Sexual Orientation and Gender Identity Minority Youth During Coronavirus Disease 2019

BackgroundFunctional tic disorders are among the least common functional movement disorders, but their prevalence rose during the coronavirus disease 2019 (COVID-19) pandemic. Although female adolescents develop functional neurological disorders at higher rates than males, investigations into sexual orientation and gender identity (SOGI) status of these patients are limited. MethodsWe completed a retrospective, cross-sectional time series examining the incidence of new-onset functional tic disorders in youth presenting to the Massachusetts General Hospital Movement Disorder clinics before and during the COVID-19 pandemic. Data were collected by searching for relevant International Classification of Diseases (ICD)-10 diagnostic codes in youth aged nine to 26 years using a hospital-wide data repository. Individual cases were reviewed for inclusion based on clinical criteria and expert consensus. ResultsThe prevalence of functional tic presentations in youth rose 8.6-fold from pre- to postpandemic levels (Fisher exact test P < 0.001), whereas the prevalence of developmental tic presentations pre- and postpandemic remained stable (114 vs 112). SOGI minority youth comprised 37% of those with functional tics (total n = 19). Ninety five percent of patients with functional tics identified as female, with 10% of these identifying as transgender. ConclusionsOur data confirm previously demonstrated dramatic rises in functional tic presentations during the COVID-19 pandemic and, more notably, reveal a strong association with SOGI minority status. We highlight the potential link between functional tic disorders and SOGI minority status. Providing a safe and supportive clinical environment and addressing stress linked to SOGI minority status may help to improve patient prognosis.
