The Influence of Child Protection Orientation on Child Welfare Practice

This article reports the findings of the second part of a two-part research project examining the potential for social workers to make changes in their work with families and children. While social workers in the United Kingdom have been encouraged to shift from a child protection to a child welfare orientation in their practice, such changes have been hampered by professional and organisational concern to manage risk. The research explores the influence of a child protection orientation on practice in child welfare cases. The findings, from two file analyses and interviews with twenty-six social workers, indicate that such an influence is indeed apparent. This is evidenced in two ways; firstly patterns of practice in child welfare cases are similar to those in child protection cases. Secondly, while the majority of social workers express an attitudinal desire to move towards a child welfare orientation, they still prioritise the management of risk in their practice. It is argued that social workers need permission from their employing organisations to make changes in their practice. This, in turn, requires such organisations to state clear goals in line with a child welfare orientation and develop holistic strategies to achieve these.

Total Synthesis of (±)-Phomactin G, a Platelet Activating Factor Antagonist from the Marine Fungus Phoma sp.

A total synthesis of phomactin G (3), which is a central intermediate in the biosynthesis of phomactin A (5) in Phoma sp. is described. The synthesis is based on a Cr(II)/Ni(II) macrocyclisation from the aldehyde vinyl iodide 9, leading to 16, followed by sequential conversion of 16 into the -epoxide 21 and the ketone 25 which, on deprotection, led to (±)-phomactin G. Phomactin G (3) shares an interesting structural homology with phomactin D (2), the most potent PAF-antagonist metabolite in Phoma sp. It is most likely converted into phomactin A (5), by initial allylic oxidation to the transient -alcohol phomactin structure 4, known as Sch 49028, followed by spontaneous pyran ring formation.

A concise and convergent (formal) total synthesis of huperzine A

The first convergent synthesis of the tricyclic skeleton of huperzine A is described and includes, as the key step, an efficient regioselective intramolecular Heck reaction of 2-(tert-butyldimethylsillyoxymethyl)-6-(2-methoxy-5-bromopyridin-6-yl)methylcyclohex-2-enol.

Do Total and High Density Lipoprotein Cholesterol and Triglycerides Act Independently in the Prediction of Ischemic Heart Disease? Ten-Year Follow-Up of Caerphilly and Speedwell Cohorts

Several studies have suggested that men with raised plasma triglycerides (TGs) in combination with adverse levels of other lipids may be at special risk of subsequent ischemic heart disease (IHD). We examined the independent and combined effects of plasma lipids at 10 years of follow-up. We measured fasting TGs, total cholesterol (TC), and high density lipoprotein cholesterol (HDLC) in 4362 men (aged 45 to 63 years) from 2 study populations and reexamined them at intervals during a 10-year follow-up. Major IHD events (death from IHD, clinical myocardial infarction, or ECG-defined myocardial infarction) were recorded. Five hundred thirty-three major IHD events occurred. All 3 lipids were strongly and independently predictive of IHD after 10 years of follow-up. Subjects were then divided into 27 groups (ie, 33) by the tertiles of TGs, TC, and HDLC. The number of events observed in each group was compared with that predicted by a logistic regression model, which included terms for the 3 lipids (without interactions) and potential confounding variables. The incidence of IHD was 22.6% in the group with the lipid risk factor combination with the highest expected risk (high TGs, high TC, and low HDLC) and 4.7% in the group with the lowest expected risk (P
