ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions – V. Hierarchical fragmentation and gas dynamics in IRDC G034.43+00.24

We present new 3-mm continuum and molecular lines observations from the ATOMS survey towards the massive protostellar clump, MM1, located in the filamentary infrared dark cloud (IRDC), G034.43+00.24 (G34). The lines observed are the tracers of either dense gas (e.g. HCO+/(HCO+)-C-13 J= 1-0) or outflows (e.g. CS J = 2-1). The most complete picture to date of seven cores in MM1 is revealed by dust continuum emission. These cores are found to be gravitationally bound, with virial parameter, alpha(vir) < 2. At least four outflows are identified in MM1 with a total outflowing mass of similar to 45 M-circle dot, and a total energy of 1 x 10(47) erg, typical of outflows from a B0-type star. Evidence of hierarchical fragmentation, where turbulence dominates over thermal pressure, is observed at both the cloud and the clump scales. This could be linked to the scale-dependent, dynamical mass inflow/accretion on clump and core scales. We therefore suggest that the G34 cloud could be undergoing a dynamical mass inflow/accretion process linked to the multiscale fragmentation, which leads to the sequential formation of fragments of the initial cloud, clumps, and ultimately dense cores, the sites of star formation.Peer reviewe

How mothers with borderline personality disorder relate to their year-old infants

Background Women with borderline personality disorder have conflictual interpersonal relations that may extend to disrupted patterns of interaction with their infants. Aims To assess how women with borderline personality disorder engage with their 12 to 18-month-old infants in separation–reunion episodes. Method We videotaped mother–infant interactions in separation–reunion episodes of the Strange Situation test. The mothers were women with borderline personality disorder, with depression, or without psychopathological disorder. Masked ratings of maternal behaviour were made with the Atypical Maternal Behavior Instrument for Assessment and Classification. Results As predicted, a higher proportion (85%) of women with borderline personality disorder than women in the comparison groups showed disrupted affective communication with their infants. They were also distinguished by the prevalence of frightened/disoriented behaviour. Conclusions Maternal borderline personality disorder is associated with dysregulated mother–infant communication

Infant genotype may moderate sensitivity to maternal affective communications: Attachment disorganization, quality of care, and the DRD4 polymorphism

Disorganized attachment is an early predictor of the development of psychopathology in childhood and adolescence. Lyons-Ruth, Bronfman, and Parsons (1999) developed the AMBIANCE coding scheme to assess disrupted communication between mother and infant, and reported the link between maternal behavior and disorganized attachment. The Hungarian group found an association between a polymorphism of the DRD4 gene and disorganized attachment (Gervai et al., 2005; Lakatos et al., 2000, 2002). The present collaborative work investigated the interplay between genetic and caregiving contributions to disorganized attachment. Mother–infant dyads (138), from a Hungarian low-social-risk sample (96) and a US high-social-risk sample (42), were assessed for infant disorganized attachment behavior, for DRD4 gene polymorphisms, and for disrupted forms of maternal affective communication with the infant. In accord with literature reports, we found a robust main effect of maternal AMBIANCE scores on infant disorganization. However, this relation held only for the majority of infants who carried the short form of the DRD4 allele. Among carriers of the 7-repeat DRD4 allele, there was no relation between quality of maternal communication and infant disorganization. This interaction effect was independent of degree of social risk and maternal DRD4 genotype

Impacto do suicídio da pessoa idosa em suas famílias Impact of suicide of the elderly on their families

Apresenta-se uma análise sobre o impacto do suicídio de idosos, na dinâmica de suas famílias. O artigo é fruto de um tipo de pesquisa qualitativa a que se denomina autópsia psicossocial e está baseado em entrevistas com familiares de 51 idosos suicidas de 10 cidades brasileiras. O estudo nessas localidades foi definido por levantamento epidemiológico que revelou a relevância do fenômeno. Foram vários os temas analisados na investigação. Mas este texto se debruça sobre como a família enfrentou a morte da pessoa idosa, suas impressões sobre o ato e as repercussões nos seus membros e na rede social. A partir da análise compreensiva dos depoimentos, foram construídos os seguintes núcleos de sentido: culpa pelo ato, isolamento social e suas manifestações na saúde, estigma e preconceito social, sofrimento familiar e perspectivas de superação, raiva e crença na improbabilidade do ato e atenção aos familiares. As famílias manifestaram sofrimento, tristeza e perplexidade pela morte do idoso, o que influi e tem repercussões na sua dinâmica e no âmbito individual. Tais consequências são diferenciadas nos locais pesquisados e dependendo das experiências da família com atos dessa natureza.<br>The scope of this paper is an analysis of suicide of elderly people and the impact on the dynamics of their families is presented. The method used is of the qualitative research type known as psychosocial autopsy and is based on interviews with the family members of 51 elderly people who committed suicide in 10 Brazilian cities. The study in these cities was defined by epidemiological research that revealed the relevance of this phenomenon. Many themes were analyzed in the investigation. However, this text focuses on how the families coped with the death of the elderly person, their impressions regarding the act, and the repercussions on family members and the social network. Pursuant to a comprehensive analysis of the testimonies, the following nuclei of significance were revealed: feelings of guilt for the act; social isolation and its manifestations on health; social stigma and prejudice; prospects of overcoming family suffering; anger and feelings of the improbability of the act; and care for the family members. The families manifested suffering, sadness, and perplexity at the death of the elderly person, which influences and has repercussions on their dynamics and at an individual level. Such consequences are different in each area researched depending on the experiences the family has had with acts of this nature
