The Conversational Model and Child and Family Counselling: Treating Chronic Complex Trauma in a Systemic Framework

Child and Family Counselling Teams in NSW Community Health Services are expected to provide therapeutic services to children who have experienced complex trauma. However, parental trauma is often overlooked or referred elsewhere. A systemic perspective informed by attachment theory and trauma theory provides the basis for addressing parental trauma in Child and Family Counselling Teams, thereby improving parenting. The Conversational Model is an evidence‐based intervention for chronic complex trauma. The foundations of the Conversational Model and its brief component, Short Term Intensive Psychodynamic Psychotherapy, are outlined and a case study is given to illustrate the usefulness of the intervention in Child and Family Counselling. Highlighted is the importance of addressing systemic trauma through parenting to improve attachment quality, family relationships, and children's function.     

The constantly changing face of chromatin

Many recent findings have altered our vision of chromatin and its role in the regulation of cellular functions. Our perspective concerning chromatin has changed to a much more complex, but also more dynamic, view of chromatin as an entity that is intimately involved in the regulation of a variety of cellular functions. In this review, we describe the various types of proteins that alter the structure and, therefore, the function of chromatin and discuss the possible role of chromatin in cell aging. The elucidation of the mechanisms that link chromatin to aging will be one of the most exciting and striking advancements in the coming years     

Richness, composition and trophic niche of stingless bee assemblages in urban forest remnants

Few studies directly address the consequences of habitat fragmentation for pollinating insect communities, particularly for the neotropical key pollinator group of stingless bees. Most studies on bees have defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Their conclusion is that habitat fragmentation is broadly deleterious; however, there are contrasting results in the literature. Insightful studies on habitat fragmentation and bees should consider fragmentation, alteration and loss of nesting habitats—not just patches of forage plants –, as well as the permeability of the surrounding matrix to interpatch movement. Here we investigated the effects of fragmentation caused by urbanization on stingless bee species’ composition and richness, as well as the permeability of the surrounding matrix. We collected bees from flowering plants and recorded phytosociological variables of five forest remnants (ranging from 64 ha to 900 ha) in southeastern Brazil. Large fragments did not contain more species per unit area than smaller ones; in fact, we found more species in small fragments, most of which were generalist bees. The presence of more habitat generalist stingless bee species was also correlated to the structure of vegetation in these fragments. In conclusion, the quality of the habitat within a fragment (structure of vegetation) as well as the quality of the matrix has a direct relation to the bee species composition. This can be seen in the direct relationship between structural diversity of the environment and age of the fragments. The matrix that holds the most recent fragments, probably due to the sprawl of the city, is more heterogeneous than the one with the oldest fragments. The most heterogeneous matrices have a certain balance between the trees, buildings and bare soil or herbaceous vegetation coverage, making the array less impermeable to bees.     

Insects on urban plants: contrasting the flower head feeding assemblages on native and exotic hosts

Exotic plant species very often comprise a large proportion of urban floras. Because herbivorous insects depend on the presence of suitable host plants to maintain their populations, it is imperative to elucidate the relative importance of native and exotic hosts to understand the response of herbivorous guilds to urbanization. By using a plant-herbivore system composed of Asteraceae hosts and flower-head endophagous insects, we investigated whether the diversity and composition of herbivorous insects differs between native and exotic host-plant species in an urban environment. Although we found only seven exotic Asteraceae among the 30 species recorded, the overall abundance of exotics was considerably greater than that of native host plants. Overall, the exotic host species supported a small subset of the herbivore assemblage found on the native ones. The number of herbivore species per host species was significantly higher among the native plants, but we did not find a difference in herbivore abundance. Moreover, the higher taxonomic composition of herbivores on exotic Asteraceae was reduced, being composed of only three genera and two families from a total of 16 genera and six families of herbivores. These results provide support for the idea that plants outside of their original geographic distribution have lower loads of enemies than phylogenetically related native species. Our findings indicate that native host plants in urban areas play a critical role in supporting the native herbivorous insect fauna.

Conversations of Care: A Narrative Review of Collaborative Care Systems for Foster and Kinship Care

This paper reviews the literature on human relational factors and their impact on complex care systems for a highly vulnerable population of children and young people in out‐of‐home care (OOHC). Factors contributing to the functioning of collaborative OOHC systems are reviewed from theoretical and contextual perspectives. The authors posit that secondary traumatic stress and vicarious trauma are central to understanding the impact of relational trauma and the experience of individuals, families, teams, and the wider ecology of collaborative care systems. Given the challenges of working collaboratively across interpersonal, family, and systems boundaries to support traumatised children in OOHC, further research is required.
