Habitat and seasonal effects on blowfly ecology in possum carcasses in the Manawatu : a thesis presented in partial fulfilment for the requirements for the degree of Master of Science in Ecology at Massey University

Flies were trapped on Keeble farm and in Keeble forest reserve between May 1992 to February 1993. Fewer Calliphoridae were trapped in pasture during summer than in autumn or winter and different fly species showed differing preferences for bush or pasture at different times of the year. More flies were trapped around the bush margin than in either bush or pasture during spring and summer. In pasture the most numerous calliphorid trapped was Calliphora stygia (Fabricius, 1781), whereas in bush during summer Calliphora hilli Patton, 1925 was the predominant species. Lucilia sericata (Meigen, 1826) was never trapped in bush. Decaying possum carcases were examined in bush and pasture between February 1992 and February 1993. The number of maggots that left these carcases was affected by the time of the year and whether the carcases were in bush or pasture. More maggots left bush located possum carcases during spring and summer while more maggots left possum carcases in pasture during autumn and winter. Decay rates were most rapid during spring and summer. Temperatures were warm enough for adult fly activity during winter but the possum carcases decayed much slower, especially in bush. C, stygia and Calliphora vicina Robineau-Desvoidy, 1830 were generally the first species of maggot to leave possum carcases and they were the only species present throughout the year in both habitats. L. sericata and Chrysomya ruficacies (Macquart, 1843) maggots were restricted to possum carcases in pasture during spring and summer while Calliphoroides antennaris (Hutton, 1881) was restricted to possum carcases in bush. Hydrotaea rostrata Robineau-Desvoidy, 1830 was the only species restricted to summer. In spring 1992, 3400 flies emerged from a 2.5 kg possum carcase placed in pasture and 4200 flies emerged from a 3.1 kg possum carcase placed in bush. Estimated emergence success of adult flies was 22.0% in pasture and 20.2% in bush. This was l5% lower on average than the emergence level of comparable maggots raised in the laboratory. Flies began emerging in the bush l0 days after those in pasture. L. sericata was restricted to pasture and C. antennatis was restricted to bush. Overall the major flystrike species to emerge were C. stygia and L. sericata. C. stygia made stygia made up 46% of the total number of flies that emerged in pasture and 78% of those in bush, while L. sericata comprised l5.5% of the total number of flies that emerged in pasture. The emergence success of field-collected maggots in the laboratory was significantly correlated with the estimated average total number of maggots that left the carcases in the field. Maggots showed the highest emergence success in winter when larval competition in the carcase was lowest. The temperature of a possum carcase containing fly maggots in bush reached 19.7° C during spring 1992 whereas the temperature exceeded 35°C on occasions in another carcase in pasture at the same time. Proportionally fewer maggots emerged from the possum carcase in pasture possibly because the high temperatures killed many maggots, especially those of C. stygia. Maggots and bacterial decay both elevated carcase temperatures above ambient. Bacteria raised the temperature by about 2°C whereas maggots raised the temperature by 18.3°C to 26°C above ambient. The carcase temperature significantly affected the number of maggots that left the possum carcases, and the number of maggots that left was directly related to the total maggot biomass that left the carcase. A minimum of 24% to 26% of. the fresh weight of the possum carcases was converted to maggot weight

'As a matter of fact I've just about had enough'; : battle weariness and the 2nd New Zealand division during the Italian campaign, 1943-45 : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in History at Massey University, Palmerston North, New Zealand

By the time that the 2nd New Zealand Division reached Italy in late 1943, many of the soldiers within it had been overseas since early 1941. Most had fought across North Africa during 1942/43 – some had even seen combat earlier, in Greece and Crete in 1941. The strain of combat was beginning to show, a fact recognised by the division’s commanding officer, Lieutenant-General Bernard Freyberg. Freyberg used the term ‘battle weary’ to describe both the division and the men within it on a number of occasions throughout 1944, suggesting at one stage the New Zealanders be withdrawn from operations completely. This study examines key factors that drove battle weariness within the division: issues around manpower, the operational difficulties faced by the division in Italy, the skill and tenacity of their German opponent, and the realities of modern combat. Critical to understanding the links between these factors and the weariness that manifested itself within the division are the words of the participating soldiers themselves. Three key outcomes of battle weariness are examined in some detail. Exposure to long periods of combat meant that a large number of the New Zealanders were at risk of becoming psychological casualties. Indeed, casualties diagnosed and recorded as exhaustion and neurosis, consistently reached over 20% of those wounded during the period in Italy. Declining morale became an issue for the leadership of 2nd New Zealand Division. Internal censorship of outgoing letters within the division was summarised at the time and these summaries provide an insight into a widespread gloomy outlook that featured throughout 1944. Not only did the letter writers reflect on the poor conditions they faced in Italy, but news from home appears as a significant driver of frontline morale. Lack of discipline – both in and out of the line – caused real concern to senior officers, and at times reached levels that appear to have become institutionalised. Three topics are explored: looting, the use of alcohol, and cases of combat refusal. This work then examines how the underlying issues driving weariness were addressed through the restructuring of the division, the replacement of long serving men, the use of new technologies, and a period of relief out of the line with an extensive training programme. Finally, the division’s performance during the final offensive in Italy in April 1945, is examined, to gauge the success of the changes made

Combination inhaled steroid and long-acting beta2-agonist versus tiotropium for chronic obstructive pulmonary disease

Background Combination therapy (inhaled corticosteroids and long-acting beta(2)-agonists) and tiotropium are both used in the treatment of chronic obstructive pulmonary disease (COPD). There is uncertainty about the relative benefits and harms of these treatments. Objectives To assess the relative effects of inhaled combination therapy and tiotropium on patients with COPD. Search strategy We searched the Cochrane Airways Group Specialised Register of trials (March 2010) and reference lists of articles. We also contacted authors of the studies.Selection criteriaWe included only parallel, randomised controlled trials comparing inhaled combination corticosteroid and long-acting beta(2)-agonist against inhaled tiotropium bromide. Data collection and analysis Two authors independently assessed trials for inclusion and then extracted data on trial quality and outcome results. We contacted study authors for additional information. Discrepancies were resolved through discussion. Main results One large two year trial (INSPIRE) and two smaller, shorter trials (Dawber 2005; SCO40034) were found. The results from these trials were not pooled. The number of withdrawals from each arm of the INSPIRE trial was large and imbalanced and outcome data was not collected for patients who withdrew, raising concerns about the reliability of data from this study.In INSPIRE, there were more deaths on tiotropium than on fluticasone/salmeterol (Peto OR 0.55; 95% CI 0.33 to 0.93). This was a statistically significant difference, however the number of withdrawals from each of the arms was eleven times larger than the observed number of deaths for participants on fluticasone/salmeterol and seven times larger for participants on tiotropium. There were more all cause hospital admissions in patents on fluticasone/salmeterol than those on tiotropium in INSPIRE (Peto OR 1.32; 95% CI 1.04 to 1.67). There was no statistically significant difference in hospital admissions due to exacerbations, the primary outcome of INSPIRE. There was no significant difference in exacerbations in patients on fluticasone/salmeterol compared to tiotropium. Exacerbations requiring treatment with oral corticosteroids were less frequent in patients on fluticasone/salmeterol (Rate Ratio 0.81; 95% CI 0.67 to 0.99). Conversely exacerbations requiring treatment with antibiotics were more frequent in patients treated with fluticasone/salmeterol (Rate Ratio 1.19; 95% CI 1.02 to 1.38). There were more cases of pneumonia in patients on fluticasone/salmeterol than those on tiotropium (Peto OR 2.13; 95% CI 1.33 to 3.40). Confidence intervals for these outcomes do not reflect the additional uncertainty arising from unknown outcome data for patients who withdrew. Authors' conclusions Since the proportion of missing outcome data compared to the observed outcome data is enough to induce a clinically relevant bias in the intervention effect, the relative efficacy and safety of combined inhalers and tiotropium remains uncertain. Further large, long-term randomised controlled trials comparing combination therapy to tiotropium are required, including adequate follow-up of all participants randomised (similar to the procedures undertaken in TORCH and UPLIFT). Additional studies comparing alternative inhaled LABA/steroid combination therapies with tiotropium are also required

Food Price Changes and Consumer Welfare in Ghana in the 1990s

In this paper, we analyse the effect of food price changes on household consumption in Ghana during the 1990s and assess the extent to which changes can be explained by trade and agricultural policy reforms. The measurement of the total household welfare effect, one that jointly considers (static) first order effects as well as (dynamic) consumption responses, is the object of this study. Food consumption behaviour in Ghana is analyzed by estimating a complete food demand system using the linear approximate version of the AIDS model with household survey data for 1991/92 and 1998/99. The estimated price elasticities are then utilized to evaluate the distributional impacts of the relative food price changes in terms of compensating variation. The results indicate that the distributional burden of higher food prices fell mainly on the urban poor. While it is difficult to attribute the price changes and by implication the welfare losses, to any particular policy per se, a simulation analysis indicates that trade liberalisation may not have been responsible for the welfare losses. Our simulation exercise suggests that further tariff liberalisation would tend to offset the welfare losses for all households although it is the poor and rural consumers who stand to gain the most.Food prices, Demand analysis, Consumer behaviour, Welfare, Ghana
