Creating paths to family justice: Briefing paper and report on key findings
This is the final version.This report sets out the findings of of work undertaken as part of an ESRC Impact Accelerator Account project where the academic authors worked with policy makers, relationship charities and family practitioners to put the findings from the academic study Mapping Paths to Family Justice into practice in the new family justice landscape to help fill the access to justice gap following the withdrawal of legal aid for legal advice and representation in most private family law disputes. It looks at how online tools and programmes and better family mediation practice might be achieved and draws on the expertise of the stakeholders alongside research evidenceEconomic and Social Research Council (ESRC)Economic and Social Research Council (ESRC)Economic and Social Research Council (ESRC

PRELIMINARY LABORATORY AND FIELD TRIALS OF CURB, A POSSIBLE AVIAN REPELLENT
Grape growers in California lose between three and four million dollars annually from damage caused principally by two bird species: Linnets (carpodacus mexicanus) and Starlings (sturnus vulgaris) (DeHaven, 1974; Crase, et al., 1975),. Few effective tools exist for the growers to use in reducing crop losses from bird damage; and current bio-political trends may preclude the use of toxicants to control local depredating bird populations, especially Linnets. The use of chemical repellents is a possible alternative. Testing of the chemical repellent methiocarb [3,5-dimethyl-4-(methylthio) phenol methylcarbamate] to protect California wine grapes has been conducted by Denver Wildlife Research Center personnel (Guarino, 1972; DeHaven, 1974; Crase, et al., 1975; and Crase & DeHaven, 1976). Results with methiocarb on grapes appear successful on a small scale. Other researchers (Stone & Toms, 1970) investigated a compound called CURB, aluminum am- monium sulfate, and obtained limited success when used on vegetable, cereal, and fruit crops including grapes. Leinati (1968) used CURB as a seed dressing to reduce seedling pulling by pheasants. Dar (1974) completed a series of trials at eight different Israeli agricultural stations, using CURB on seedling sugar beets, cucumbers, radishes, lettuce, celery, beans, kohlrabi, and strawberries. Data indicate that CURB provides good protection for plants with large leaf surface area, but results of trials to reduce seedling pulling by birds varied too much for valid conclusions. Trials on legumes raised for seed and sorghum were encouraging. Tests with CURB-treated wine grapes in Australia and South Africa have yielded inconclusive results about its effectiveness as an avian repellent. In Israel, specialists indicate that the metallic salts of CURB affect wine flavor (Stone, 1976). Although test results with CURB appear variable and inconclusive, General Vineyard Services in Salinas Valley, California, offered grape acreage for test plots to evaluate the potential of CURB as an avian repellent.

Interactions of asbestos-activated macrophages with an experimental fibrosarcoma
Supernatants from in vivo asbestos-activated macrophages failed to show any cytostatic activity against a syngeneic fibrosarcoma cell line in vitro. UICC chrysotile-induced peritoneal exudate cells also failed to demonstrate any growth inhibitory effect on the same cells in Winn assays of tumor growth. Mixing UICC crocidolite with inoculated tumor cells resulted in a dose-dependent inhibition of tumor growth; this could, however, be explained by a direct cytostatic effect on the tumor cells of high doses of crocidolite, which was observed in vitro
