The GINI project investigates the dynamics of inequality among populations over the long term by synthesising global archaeological housing data. This project brings archaeologists together from around the world to assess hypotheses concerning the causes and consequences of inequality that are of relevance to contemporary societies globally.

Child protection is considered an appropriate government responsibility, but interventions into the family are also some of the most consequential for states. This study examines the normative basis for limiting parents’ freedom by exploring public attitudes about a child’s safety in the context of increasing risk. Using a randomized survey, we test the causal relationship between levels of risk and parental restrictions on representative samples in Norway and CA, US (n = 2148) – different welfare state and child protection models. Findings suggest that the public supports restricting parental freedom under conditions of risk and that severity of risk is taken into consideration. A majority favour restricting parental freedom under conditions of risk to the child; a minority resist restricting freedom, regardless of risk, and about one-third to one-half of respondents favour temporarily suspending parents’ rights by separating children to foster care. Residents of Norway are half as likely to support unrestricted parenting, regardless of risk, and are 1.5 as likely to endorse restricted parenting. Norwegians are also 20% less likely to support separating a child from his parent compared to US respondents. The study has implications for system design based on popular notions about parents’ freedom and family privacy.

Under laboratory and field conditions in Ontario, Canada, we explored the natural history of Phasgonophora sulcata Westwood (Hymenoptera: Chalcididae), an indigenous solitary endoparasitoid of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) in North America. Adult P. sulcata emergence was ~20.2–23.9 days after host emergence at 21°C, with P. sulcata females emerging an ~5.4–5.8 days before males. Females also represented 61.8 and 67.0% of emerging adults in the two years sampled. Mean adult longevities for males and females of P. sulcata were 23.8±1.10 and 28.9±1.11 days at 21°C, respectively. Mean potential fecundity of P. sulcata at emergence was 55.7±2.9 eggs per female. Based on adult emergence, parasitism at two sites varied from 11.7% to 34.4%. Adult parasitoids were first observed in the field in early June, with peak capture occurring in late June. Parasitism rates in A. planipennis-infested ash trees was not affected by tree height below 360 cm, whereas parasitism was not observed at heights>360 cm. Our results suggest that although mass rearing will be challenging, observed parasitism rates in conjunction with temporal and spatial synchrony indicate that indigenous P. sulcata may be an important source of mortality for A. planipennis populations.

Phasgonophora sulcata Westwood (Hymenoptera: Chalcididae) is a North American parasitoid now using Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) as a novel host, and may prove useful in biocontrol. Unfortunately, information is lacking regarding mating and the presence of pheromones, which may be important when attempting to exploit this parasitoid within a management context. Herein we used olfactometer assays and behavioural observations to determine the courtship and mating sequences of P. sulcata. A significantly higher proportion of males oriented towards females over the control arm containing filtered air in an olfactometer regardless of the age classes of females or males examined. We also observed four pre-copulatory behaviours that were consistent in all mating pairs. Our results indicate that courtship may be mediated by male perception of female-produced pheromones. Understanding the courtship sequence may be useful in rearing laboratory populations, while the putative pheromones may be useful in detection and retention of P. sulcata populations.

This research combines National Election Study (NES) data with data on congressional candidate quality and spending to assess explanations for ticket splitting. The results indicate characteristics of both voters and candidates are important, but candidate-level variables as a whole provide a better account of ticket splitting than individual-level variables. NES data are also used to evaluate the reasons why candidate quality and spending are so important. Candidates encourage ticket splitting through various campaign activities, especially those that are unmediated. Additionally, incumbents benefit from constituency service and pork barrel legislation, which foster ticket splitting among voters in their districts.

In recent years big bale silage (BBS) made in large plastic bags has become an increasingly popular method of grass conservation with one estimate (Catt, 1986) suggesting that 30% of all grass silage in the UK was conserved in this way in 1985.

In general BBS is drier than clamp silage (CS) (Butler, 1983) primarily for economic reasons related to contracters.charges for baling the reduced number of bales compared to wet silage. There are however few comparative data on concentrations of fermentation acids and it is not clear whether the fermentation characteristics of BBS are different from CS or merely a function of differences in dry matter content.
