Paternal Relationships Research Articles

Влияние родительского отношения на формирование личности несовершеннолетнего с правонарушающим поведением

The article considers the parental attitude as one of the main factors influencing the formation of the personality of a juvenile delinquent with delinquent behavior. The concept of "parental relationship" and its structure are studied. The author analyzes the features of destructive parental attitudes, such as shortcomings in the educational process, emotional alienation of parents, low moral level of families, deviant motherhood.
 The differences in the structure of the maternal and paternal relationship are determined. The features of negative relations between parents and minors are described, such as inconsistency, coldness, aloofness, inconsistency, disrespect, and misunderstanding. The authors also consider the causes of deviant motherhood, which consist in psychiatric and intellectual disorders of young women, resulting from violence, abuse in childhood, improper upbringing, as well as due to the influence of social factors, such as the low level of education of women, poverty, and unemployment.
 The article is written on the basis of a study conducted on the basis of the methodology for diagnosing parental attitudes developed by A. Ya. Varga and V. V. Stolin, parents of minors with law-abiding and delinquent behavior took part in the survey.
 As a result of the study, it was found that parents treated minors with delinquent behavior more coldly, distanced and alienated, and showed little attention to their lives than to law-abiding minors.

Parentage analysis using genome-wide high-density SNP microarray.

Parentage analysis is a technology that uses genetic methods to verify or exclude relationships between individuals. STR technology is often used in parentage analysis. We received three sets of samples from three families. Each set of samples consisted of a male individual and a female individual. Their test requirements were meant to determine whether they were a paternity relationship, a sibling relationship, or grandparent-grandchild relationship. However, only one STR locus mismatch was detected in each group. Other family members to assist in testing could not be identified; therefore, other methods were needed to assist in judgment. Using high-density SNP microarrays, we analyzed the feasibility of its application in paternity analysis. A total of 180 samples were tested, including 100 unrelated samples, and 74 samples from 30 families, and six samples from three families. The data were analyzed, grouped according to the chromosome of SNP, and the mismatching rate was counted. The total mismatching rate of SNP in unrelated individuals was 8-10 times higher than that of parent-child individuals. Individuals with a total mismatch rate of more than 5.3% were defined as individuals with no kinship, and the individuals with a total mismatch rate of less than 0.6% were defined as the individuals with a parent-child relationship. Through the use of high-density gene chips for analysis, we also completed an auxiliary analysis of the kinship of the three families. The gene chip is a better method for auxiliary analysis of the kinship between individuals.

Tales from the Supplementary Information: Ancestry Change in Chalcolithic–Early Bronze Age Britain Was Gradual with Varied Kinship Organization

Large-scale archaeogenetic studies of people from prehistoric Europe tend to be broad in scope and difficult to resolve with local archaeologies. However, accompanying supplementary information often contains useful finer-scale information that is comprehensible without specific genetics expertise. Here, we show how undiscussed details provided in supplementary information of aDNA papers can provide crucial insight into patterns of ancestry change and genetic relatedness in the past by examining details relating to a >90 per cent shift in the genetic ancestry of populations who inhabited Chalcolithic and Early Bronze Age Britain (c. 2450–1600bc). While this outcome was certainly influenced by movements of communities carrying novel ancestries into Britain from continental Europe, it was unlikely to have been a simple, rapid process, potentially taking up to 16 generations, during which time there is evidence for the synchronous persistence of groups largely descended from the Neolithic populations. Insofar as genetic relationships can be assumed to have had social meaning, identification of genetic relatives in cemeteries suggests paternal relationships were important, but there is substantial variability in how genetic ties were referenced and little evidence for strict patrilocality or female exogamy.

Sense-value and the essay film: the speculative dimension of Dónal Foreman’s The Image You Missed (2018)

ABSTRACT This article explores Dónal Foreman’s 2018 essay film The Image You Missed through a trip-partite lens: sense, speculation and knowledge. Foreman navigates a life long relationship with a largely absent father, the deceased documentary filmmaker Arthur MacCaig, using a dialogic framework; an essay in the form of a conversation between Foreman and MacCaig. He turns to the essay to explore the paternal relationship as a conduit for others: sense and knowledge, documentary and reportage, speculation and fact. By exploring these in their various guises, this article argues that an aesthetically rendered image of MacCaig manifests (through audio interviews and texts that maintain the illusion of the father’s presence) as a residual haunting in the film: an affect of the archive. It is not Foreman’s aim, the article asserts, to cultivate a verifiably true image of his father from seen and unseen footage, but to ethically manufacture a dialogical conversation that involves thinking through the relationship itself. The article develops recent scholarship on the thinking of the essay film to explore the disjunctive relationship between sense and knowledge considered formative to the essay form.

Diversities of HLA-A, -B, -C, -DRB1 and -DQB1 loci in Chinese Kazak population and its genetic relatedness dissection with multiple populations: a comparative study

Studying the allele and haplotype distributions of human leukocyte antigen (HLA) loci at 2nd-field level in different populations was important. Allele and haplotype frequencies of HLA-A, -B, -C, -DRB1 and -DQB1 loci in 110 unrelated healthy Kazak individuals living in Xinjiang (China) were analyzed using polymerase chain reaction sequence based typing. Thirty HLA-A, 48 HLA-B, 24 HLA-C, 34 HLA-DRB1 and 18 HLA-DQB1 alleles were detected at the 2nd-field level in the Kazak population. Frequencies of HLA alleles, genotypes, and haplotypes were calculated, and some exhibited significantly different distributions among different populations. A neighbor-joining (NJ) tree, heatmap, multidimensional scaling (MDS) and principal component analysis (PCA) were used to explore the genetic relationships between the Kazak population and 32 reference populations distributed in Asia, Africa, America and Europe using frequency data of HLA-A, -B, -C and -DRB1 loci. The NJ tree, heatmap, and MDS of the 33 populations were constructed based on pairwise DA values of populations obtained by the HLA-A, -B, -C and -DRB1 allele frequencies. Different PCA plots were constructed based on the allele frequencies of HLA-A, -B, -C and -DRB1 or estimated haplotypic frequencies of HLA-A, -B, -C loci. The data obtained in the present research can be used for research on HLA-related diseases or paternity relationships, and aid to finding the best matched donors in stem cell transplantation for Kazak individuals.

Relationships in transition: maternal and paternal parenting styles and change in sibling dynamics during adolescence

ABSTRACT Objective The goal of the current 3-year longitudinal study was to evaluate the association between maternal and paternal parenting styles and sibling relationships during the early to late adolescent transition. Our original sample consisted of 272 particpants in grades 9 and 11 from a high school in the Northeastern US. After three years, time 2 data for 135 students from the original sample was collected. The parenting behaviour assessed was parenting styles. Sibling relationship outcomes were sibling support, warmth, and conflict. Maternal authoritative and permissive styles were associated with greater time II sibling support than maternal authoritarian and neglectful styles. Maternal authoritative style was further associated with greater time II sibling warmth than the authoritarian and neglectful styles. Paternal authoritative style was associated with greater time II sibling support than the authoritarian and neglectful styles. Additionally, although overall parenting with low levels of acceptance and involvement was associated with reduced sibling relationship quality, paternal neglectful parenting style was associated with greater increases over time in sibling support than the other paternal parenting styles. Cohort effects were also found for sibling support and conflict. The results highlight the continuous contribution parenting behaviours have on sibling relationship quality during adolescence. The findings point to potential compensatory support offered by siblings in early and late adolescence.

Polymorphism and Forensic Application of 11 Y-SNP in Guizhou Shui Ethnic Group

Objective To investigate the frequency distribution features of 11 Y-SNP of Guizhou Shui ethnic group, explore its genetic relationship with other ethnic groups and evaluate its forensic application value. Methods Multiplex amplification of the 11 Y-SNP of samples of 180 unrelated male individuals from Guizhou Shui ethnic group was performed with microsequencing technique. The frequency of haplogroup was calculated by direct counting method, and principal component analysis （PCA） of Guizhou Shui ethnic group and reference ethnic groups was performed by using Multi-variate statistical package （MVSP）. The Fst genetic distance between Guizhou Shui ethnic group and other ethnic groups was calculated with Arlequin v3.5. The phylogenetic tree was established with MEGA 4.0 software according to the Fst value. Results Six types of Y chromosome haplogroups were observed in total. Among which, the distribution frequency of O-M175 haplogroup was the highest （71.11%）, followed by C-M130 （25.00%）, and D-M174 （3.89%）. O1b-M268 （31.11%） and O2a2-IMS-JST021354 （28.33%） had a relatively high distribution frequency in O haplogroup. The paternal relationship between Guizhou Shui ethnic group and Guizhou Gelao ethnic group in the same language group was the closest. Conclusion The distribution of Y-SNP haplogroup of the Shui ethnic group in Guizhou has certain specificity, which can provide basic data for forensic biogeographic inference.

Dysfunctional Career Thoughts and Perceived Quality of Parental Relationships in Adolescents With Attention‐Deficit/Hyperactivity Disorder

Attention‐deficit/hyperactivity disorder (ADHD) is known to cause significant difficulties in interpersonal relationships. Empirical research in career development has demonstrated that close, supportive relationships are associated with positive vocational behaviors (Kenny et al., 2018). We examined dysfunctional career thoughts and perceived quality of parental relationships in high school students with ADHD. One hundred two adolescents (76 boys, 26 girls) with ADHD responded to measures of career thoughts and interpersonal relationship quality. Preliminary exploratory analysis, using multiple linear regression, showed that male participants' dysfunctional career thoughts were statistically significantly related to their relationships with their mothers. For female participants, relationships with fathers represented an area for further exploration. Results suggest that career professionals can enhance positive outcomes of decision‐making and problem‐solving issues in adolescence with additional focus on relational interventions. Future research should incorporate the influence of gender and race/ethnicity on crucial relationships and focus on paternal relationships using cognitive information processing–based interventions with this population.

EPIC markers of the genus Apis as diagnostic tools for detection of honey fraud

The entomological source of honey is linked to its origin and may substantially contribute to the end products' price. For example, honey from native and/or non-domesticated species, such as Asian Apis dorsata and Apis cerana, is more valued and achieves higher prices compared to the honey from managed colonies of A. mellifera. Such types of honey are often subject to various fraudulent practices, such as mislabelling of the origin or admixing with lower-cost and low-quality honey which does not match the label declaration. The entomological origin may be determined through DNA-based techniques. Here, we report on new DNA-based tools for the correct identification of the DNA signatures of three economically important honeybee species: Apis mellifera, Apis cerana, and Apis dorsata. Initially, we constructed EPIC markers for a nuclear single-copy adenine nucleotide translocase (ANT) gene to explore the properties of interspecific variation in honeybee tissue samples. For confirmation of the samples’ identity, we used widespread mitochondrial tRNALeu – cox2 marker. Based on successful sequencing and phylogenetic analyses, we identified a short interspecifically variable part in the ANT gene for which we designed PCR primers that allow the successful amplification of fragmented DNA from sources like honey. Amplified fragments were differentially double digested by restriction endonucleases MnlI and HpaI, which resulted in specific restriction patterns observed on agarose gel electrophoresis. Verification of the approach was performed with 25 tissue samples and tested additionally with 20 honey samples and 1 royal jelly sample. Our results demonstrate the correct assignment of the samples to their entomological origin on the interspecific level.Furthermore, PCR amplification using the designed EPIC marker and double restriction protocol was demonstrated as useful in detecting mixed samples as well as two mislabelled honey samples claimed to belong to Asian honeybee Apis cerana. Additionally, EPIC markers are also useful in detecting heterozygosity, for example, in tracing paternal and maternal lines in contrast to abundantly used mitochondrial tRNALeu – cox2, which is inherited via maternal line only and may thus significantly contribute to the resolving of paternal relationships. We show that our method is not limited to honey but may also be applied to other honeybee products, such as royal jelly.

Identification and characterization of novel rapidly mutating Y-chromosomal short tandem repeat markers.

Short tandem repeat polymorphisms on the male-specific part of the human Y-chromosome (Y-STRs) are valuable tools in many areas of human genetics. Although their paternal inheritance and moderate mutation rate (~10-3 mutations per marker per meiosis) allow detecting paternal relationships, they typically fail to separate male relatives. Previously, we identified 13 Y-STR markers with untypically high mutation rates (>10-2 ), termed rapidly mutating (RM) Y-STRs, and showed that they improved male relative differentiation over standard Y-STRs. By applying a newly developed in silico search approach to the Y-chromosome reference sequence, we identified 27 novel RM Y-STR candidates. Genotyping them in 1,616 DNA-confirmed father-son pairs for mutation rate estimation empirically highlighted 12 novel RM Y-STRs. Their capacity to differentiate males related by 1, 2, and 3 meioses was 27%, 47%, and 61%, respectively, while for all 25 currently known RM Y-STRs, it was 44%, 69%, and 83%. Of the 647 Y-STR mutations observed in total, almost all were single repeat changes, repeat gains, and losses were well balanced; allele length and fathers' age were positively correlated with mutation rate. We expect these new RM Y-STRs, together with the previously known ones, to significantly improving male relative differentiation in future human genetic applications.

Stereotypic behaviour predicts reproductive performance and litter sex ratio in giant pandas

Breeding and welfare problems confront many conservation breeding programs. Stereotypies—repetitive, unvarying, functionless behaviours —are common abnormal behaviours that often arise in suboptimal conditions. While the role of stereotypies in welfare assessment is well studied, few investigations address the relationship between stereotypic behaviour and reproduction. We examined the correlation between stereotypic behaviour and reproductive performance in 101 giant pandas (Ailuropoda melanoleuca). High stereotyping males copulated more and produced more cubs, suggesting that highly sexually motivated males were prone to stereotypy but also had high reproductive competence. Female stereotypies were negatively associated with all reproductive measures closely tied to behavioural competence: high stereotyping females were less likely to copulate, less likely to mother-rear cubs, and—probably a result of poor maternal care—had lower cub survival. However, females that exhibited stereotypies were more likely to produce a cub, suggesting stereotypies are tied to behavioural but not physiological competence. High stereotyping female pandas also displayed strong and consistent bias toward production of female offspring while paternal relationship to sex allocation was the reverse. These results are consistent with stress-mediated sex allocation theory. Our findings raise concern about differential reproductive success among high and low stereotyping pandas, and possible genetic adaptation to captivity.

Circulating Cell-Free Plasma DNA in Noninvasive Prenatal Paternity Testing with Short Tandem Repeats (STRs).

Paternity relationship can be established using STR markers in a minimally invasive manner during the prenatal period in the early weeks of pregnancy or in advanced pregnancy using circulating cell-free DNA (ccf DNA) drawn from the mother. The aim of our presentation is to demonstrate the advantages of ccf plasma DNA in establishing the paternity of an unborn child. Between mother and the alleged father (AF) of the fetus, an avuncular relationship as uncle-niece exists. As biological samples, saliva was collected with buccal swabs from the mother and AF. For the fetus, we separated plasma from drawn blood from the mother, and further, we isolated ccf DNA from the mother's plasma sample. The DNA samples were quantified on a 7500 ABI Real-Time PCR using Investigator Quantiplex Pro Kit (Qiagen, Germany). Genotyping of the DNA samples was performed on a ProFlex PCR System (Thermo Scientific, USA) using the multiplex STR markers from Global Filer PCR Amplification Kit (Thermo Scientific, USA). Further, PCR products were run on capillary electrophoresis on an ABI 3500 Genetic Analyzer (Applied Biosystems, USA). The AF was confirmed as the biological father of the child, with a probability of paternity (PP) = 99.99999% and a cumulative paternity index (CPI) = 8.300 x 103. In the case of advanced pregnancies from sexual assaults or incestuous relationships, the use of ccf DNA to establish the genetic profile of the fetus represents an advantage for establishing the paternity relationship between the fetus and AF. The method proves its efficiency as it has the advantage of speed of probation through forensic genetic expertise.

ПИСЬМА ЦАРСТВЕННЫХ ОСОБ К В.А. ЖУКОВСКОМУ И СЕМАНТИКА «СЕМЕЙСТВЕННОЙ МОНАРХИИ»

The article reviews the letters from royal persons to Vasily Zhukovsky. Based on these letters, the character of the epistolary dialogue between the poet and representatives of the Romanov dynasty and of the German dynasties is reconstructed completely for the first time. Zhukovsky was not the only writer who was warmly welcomed at court, but his case was unique. The poet organically joined the context of the new emerging ideology of “family monarchy”, in which a small circle of the imperial family, professing family and domestic values, acted as a prototype of the all-imperial unity of subjects symbolically included in the sphere of paternal relations. Moreover, Zhukovsky was one of the co-creators and translators of this ideology. In addition, Zhukovsky, originally a reader under Empress Maria Feodorovna, entered the circle of royal persons as a poet and remained so until the end of his life. It was his tireless work that designated a new stage in the interaction of power and literature. The system of literary patronage, which determined the sociocultural functioning of the 18thcentury literature, gradually faded into the past and was replaced by a system of literature friendly communities, in which informal groups were the centers of the literary process. The poet transferred these forms of communication to the court, transforming Pavlovsk and the circle of Maria Feodorovna, and then the circle of Alexandra Feodorovna, into a kind of a literary community. “Family monarchy” under the aegis of Zhukovsky acquired a distinct literary and aesthetic dimension. Art here became a necessary part of everyday life, which, on the one hand, set the standard for the royal persons’ thinking and behavior, and, on the other, opened up channels for interaction with friendly communities outside the court. The conceptual framework of “family monarchy” legitimized private and home-centered topics of communication becoming a powerful filter that set etiquette forms that hindered the possibility of discussing many issues, be it business problems or politics. Based on the letters of Grand Duke Alexander Nikolaevich, the article shows how such etiquette communication worked, including how Alexander reacted to Zhukovsky’s political reflections. On the other hand, the letters of the King of Prussia, Frederick William IV, demonstrate strategies for bypassing etiquette communication and going to informal friendly reflection. The appendix to the article is a chronological index of all known letters of the royal persons to Zhukovsky.

Korean young adults’ perceptions of fathers’ gender role conflict, depressive symptoms, and paternal relationship quality: the mediating effects of fathers’ violence

ABSTRACTThe present study tested the mediating effects of fathers’ violence on the relationships among Korean young adults’ perceptions of their fathers’ gender role conflict, the quality of their relationships with their fathers, and depressive symptoms. Three hundred fifty six Korean university students in South Korea participated in the study. The hypothesized model was tested by using structural equation modelling. Results indicated fathers’ violence fully mediated the relationship between fathers’ perceived gender role conflict for Success, Power and Competition and paternal relationship quality, and partially mediated the relationship between fathers’ perceived Restrictive Emotionality and paternal relationship quality. Fathers’ perceived Restrictive Emotionality was also associated with their own depressive symptoms. Results were contextualized within dynamics of South Korean society and culture.

Expanding Our Focus From Father Involvement to Father–Child Relationship Quality

Most of the many existing ways to conceive and measure paternal relationships incorporate ways to gauge father involvement. Although father involvement is a well‐established, important component of studying fathering relationships, it offers a circumscribed understanding of key characteristics of father–child relationships and their quality. Synthesizing theoretical and empirical literature across broader indicators of father–child relationship quality (FCRQ) affords fuller consideration of developmental trajectories of father–child relationships and outcomes for both fathers and their children. A theoretical focus on FCRQ affords enhanced understanding of the meaning and processes of father–child relationships. Implications are discussed for conceptualization, operationalization, and practical steps to enhance future FCRQ scholarship.

Paternal Y chromosomal genotyping reveals multiple large-scale admixtures in the formation of Lolo-Burmese–speaking populations in southwest China

Background: Bai and Yi people are two Tibeto-Burman speaking ethnic groups in Yunnan, southwest China. The genetic structure and history of these two groups are largely unknown due to a lack of available genetic data.Aim: To investigate the paternal genetic structure and population relationship of the Yi and Bai people.Subjects and methods: We collected samples from 278 Bai individuals and 283 Yi individuals from Yunnan and subsequently genotyped 43 phylogenetically relevant Y-SNPs in those samples. We estimated haplogroup frequencies and merged our data with a reference database including 46 representative worldwide populations to infer genetic relationships.Results: Y chromosomal haplogroup O-M175 is the dominant lineage in both Bai and Yi people. The Bai and Yi show a close genetic relationship with other Tibeto-Burman–speaking populations with high frequencies of haplogroup O2a2b1a1-Page23, which is also confirmed by PCA. The frequencies of the Tai-Kadai specific lineage O1a-M119, the southern China widespread lineage O1b-P31 and the eastern China enriched lineage O2a1b-002611, are also relatively high in our studied populations.Conclusions: The paternal Y chromosomal affinity of the Bai and Yi with Tibeto-Burman groups is consistent with the language classification. During the formation of the Bai and Yi populations, there were multiple large-scale admixtures, including the expansion of Neolithic farming populations from northern China, the assimilation of Tai-Kadai–speaking populations in southwest China, the demographic expansion driven by Neolithic agricultural revolution from southern China, and the admixture with populations of military immigration from northern and eastern China.

From maternal tending to adolescent befriending: The adolescent transition of social support.

Attachment theory holds that parental relationships have lifelong effects on offspring social lives. The tend-and-befriend hypothesis posits that female friendships among humans evolved as part of a primate-wide coping mechanism to mediate stress by relying on social support. Here we bridge developmental and evolutionary frameworks to examine adolescent girls' perception of their reliance on female friendship for social support, how perceptions of parental relationships affect peer relationships, and the extent to which parent and peer relationships buffer depressive symptoms. We predict perceived maternal relationship quality will be positively associated with close female friendships, and maternal relationships, paternal relationships, and female friendship will buffer depressive symptoms. Participants were adolescent girls from a summer science camp (N = 95). Participants filled out demographic information, social network surveys, the Parent-Adolescent Communication Scale, and the Center for Epidemiology Depression Scale. Data was analyzed with Pearson's correlations, t tests, and path analysis. Adolescent girls with few female friends, compared with girls who had more than two very close female friends, experienced more depressive symptoms (t = 3.382, p = .001, D = 0.784). Adolescent girls with few female friends experienced more depressive symptoms compared to girls with two or more very close female friends (t = 3.382, p = .001, D = 0.784). Stronger maternal and paternal relationships were associated with having more female friends (maternal: t = -3.213, p = .003, D = 0.837; paternal: t = -2.432; p = .017). In the path analysis model, only maternal relationship quality significantly predicted female friendship category (β = .33, CR = 2.770, p < .006). Furthermore, participants with two or more very close female friends and higher paternal relationship quality had significantly fewer depressive symptoms (friends; β = -.19, CR = -2.112, p = .035; paternal: β = -.33, CR = -3.220, p < .001), and older participants had more depressive symptoms (β = .17, CR = -1.931, p = .036). These results provide additional support for the tend-and-befriend hypothesis, suggesting that maternal tending sets the stage for close female friendships.

Molecular genealogy of Tusi Lu's family reveals their paternal relationship with Jochi, Genghis Khan's eldest son.

Genghis Khan's lineage has attracted both academic and general interest because of its mystery and large influence. However, the truth behind the mystery is complicated and continues to confound the scientific study. In this study, we surveyed the molecular genealogy of Northwestern China's Lu clan who claim to be the descendants of the sixth son of Genghis Khan, Toghan. We also investigated living members of the Huo and Tuo clans, who, according to oral tradition, were close male relatives of Lu clan. Using network analysis, we found that the Y-chromosomal haplotypes of Lu clan mainly belong to haplogroup C2b1a1b1-F1756, widely prevalent in Altaic-speaking populations, and are closely related to the Tore clan from Kazakhstan, who claim to be the descendants of the first son of Genghis Khan, Jochi. The most recent common ancestor of the special haplotype cluster that includes the Lu clan and Tore clan lived about 1000 years ago (YA), while the Huo and Tuo clans do not share any Y lineages with the Lu clan. In addition to the reported lineages, such as C3*-Star Cluster, R1b-M343, and Q, our results indicate that haplogroup C2b1a1b1-F1756 might be another candidate of the true Y lineage of Genghis Khan.

Y-chromosomal analysis of clan structure of Kalmyks, the only European Mongol people, and their relationship to Oirat-Mongols of Inner Asia

Kalmyks, the only Mongolic-speaking population in Europe, live in the southeast of the European Plain, in Russia. They adhere to Buddhism and speak a dialect of the Mongolian language. Historical and linguistic evidence, as well a shared clan names, suggests a common origin with Oirats of western Mongolia; yet, only a limited number of genetic studies have focused on this topic. Here we compare the paternal genetic relationship of Kalmyk clans with ethnographically related groups from Mongolia, Kyrgyzstan and China, within the context of their neighbouring populations. A phylogeny of 37 high-coverage Y-chromosome sequences, together with further genotyping of larger sample sets, reveals that all the Oirat-speaking populations studied here, including Kalmyks, share, as a dominant paternal lineage, Y-chromosomal haplogroup C3c1-M77, which is also present in several geographically distant native Siberian populations. We identify a subset of this clade, C3c1b-F6379, specifically enriched in Kalmyks as well as in Oirat-speaking clans in Inner Asia. This sub-clade coalesces at around 1500 years before present, before the Genghis Khan era, and significantly earlier than the split between Kalmyks and other Oirat speakers about 400 years ago. We also show that split between the dominant hg C variant among Buryats—C3-M407—and that of C3-F6379, took place in the Early Upper Palaeolithic, suggesting an extremely long duration for the dissipation of hg C3-M217 carriers across northern Eurasia, which cuts through today’s major linguistic phyla.

On what is read, shared, and felt: parent-child conversation about stories

ABSTRACTPicture book reading is a forum for early language development and for the development of relationships, as reading a story evokes connections between the narrative, the reader, and the child, and invites shared understanding of the story as it intersects with the child's experience. The study by Teufl and colleagues poses interesting questions about the nature and influence of parent-child discourse around picture books and how it changes developmentally. It also raises provocative questions about how we assess the relative influence of maternal and paternal attachment relationships. These issues are the focus of this commentary.
