'Like walking on eggshells': Service user views and expectations of the child protection system

This paper reports on a study of service users' views on Irish child protection services. Qualitative interviews were conducted with 67 service users, including young people between 13 and 23. The findings showed that despite refocusing and public service management reforms, service users still experience involvement with the services as intimidating and stressful and while they acknowledged opportunities to participate in the child protection process, they found the experience to be very difficult. Their definition of ‘needs’ was somewhat at odds with that suggested in official documentation, and they viewed the execution of a child protection plan more as a coercive requirement to comply with ‘tasks’ set by workers than a conjoint effort to enhance their children's welfare. As in previous studies, the data showed how the development of good relationships between workers and service users could compensate for the harsher aspects of involvement with child protection. In addition, this study demonstrated a high level of discernment on the part of service users, highlighting their expectation of quality standards in respect of courtesy, respect, accountability, transparency and practitioner expertise.

'Like waking up in a Franz Kafka novel': Service users' experiences of the child protection system when domestic violence and acrimonious separations are involved

The challenges that arise in respect of child abuse reports made in the context of domestic violence and/or acrimonious separation have been the subject of recent academic discussion. This paper adds a service user perspective to the debate and reports on the findings from a study conducted in the Republic of Ireland. In addition to the previously established evidence about such cases, it demonstrates the level of powerlessness and frustration experienced by families who found it difficult to have their needs heard or met. It also illustrates the very detrimental emotional impact on children and parents who frequently encountered indifference as well as insensitive and gendered responses from child protection staff. The findings indicate that mainstream statutory child protection services do not have the capacity to deal with these complex cases, and advocates the adoption of alternative approaches. Importantly, the study demonstrates the necessity to pay attention to the views of service users in developing an appropriate response.

A numerical investigation of the flow structures and losses for turbulent flow in 90 degrees elbow bends

Computational fluid dynamic modelling was carried out on a series of pipe bends having R/r values of 1.3, 5, and 20, with the purpose of determining the accuracy of numerical models in predicting pressure loss data from which to inform one-dimensional loss models. Four separate turbulence models were studied: the standard k-epsilon model, realizable k-epsilon model, k-omega model, and a Reynolds stress model (RSM). The results are presented for each bend in the form of upstream and downstream pressure profiles, pressure distributions along the inner and outer walls, detailed pressure and velocity fields as well as overall loss values. In each case, measured data were presented to evaluate the predictive ability of each model. The RSM was found to perform the best, producing accurate pressure loss data for bends with R/r values of 5 and 20. For the tightest bend with an R/r value of 1.3, however, predictions were significantly worse due to the presence of flow separation, stronger pressure gradients, and high streamline curvature.

Preservation methods alter stable isotope values in gelatinous zooplankton: implications for interpreting trophic ecology

Jellyfish are increasingly topical within studies of marine food webs. Stable isotope analysis represents a valuable technique to unravel the complex trophic role of these long-overlooked species. In other taxa, sample preservation has been shown to alter the isotopic values of species under consideration, potentially leading to misinterpretation of trophic ecology. To identify potential preservation effects in jellyfish, we collected Aurelia aurita from Strangford Lough (54(o)22'44.73aEuro(3)N, 5(o)32'53.44aEuro(3)W) during May 2009 and processed them using three different methods prior to isotopic analysis (unpreserved, frozen and preserved in ethanol). A distinct preservation effect was found on delta N-15 values: furthermore, preservation also influenced the positive allometric relationship between individual size and delta N-15 values. Conversely, delta C-13 values remained consistent between the three preservation methods, conflicting with previous findings for other invertebrate, fish and mammalian species. These findings have implications for incorporation of jellyfish into marine food webs and remote sampling regimes where preservation of samples is unavoidable.
