Estimating the private non-financial benefits of higher education:Cross-sectional models

This paper presents a series of models which seek to estimate the non-financial private benefits that individuals receive from higher education. At this stage, the data used in this analysis is cross-sectional only, and is mainly taken from wave 19 of the Household, Income and Labour Dynamics in Australia (HILDA) survey (two variables - Financial confidence and Field of Education history – are taken from wave 16). Previous research has generally shown that more highly educated people tend to do better on a range of health and social outcomes. In terms of non-employment related outcomes, the current analysis confirms that positive impacts can be observed on levels of self-perceived health status, BMI, psychological well-being, community relationships, levels of volunteering and levels of financial confidence, although these effects are mediated by a range of factors including age and competing employment, time and resource constraints. It is also interesting that overall, higher education graduates do not experience greater life satisfaction than non-graduates, and this result is consistent across all age groups. In terms of employment related outcomes, of the variables tested, few have positive, significant results including job satisfaction, job security satisfaction and pay satisfaction. Again, these findings accord with much of the literature on these aspects. The individual benefits of higher education can be set against the backdrop of the relative cost to gain higher education qualifications (including HELP repayment implications) as well as the associated market benefits that flow from higher education attainment

Altitudinal effects on habitat selection in two sympatric pipistrelle species

Altitude can profoundly influence the distribution of mammals, although the majority of studies of altitudinal impacts on distribution and abundance examine large-scale effects in mountainous environments. We investigate the potential for altitudinal effects on within habitat distribution in common and soprano pipistrelle bats (Pipistrellus pipistrellus and Pipistrellus pygmaeus) over relatively small scales on the Isle of Man, an island with a maximum altitude of 620 m above sea level. While we found no differences in habitat or altitude usage between the two species, both showed a sharp decline in activity with small increases in altitude within all habitats. This decline was steepest in deciduous and conifer woodland, and more gradual in arable land and heathland. Activity also declined more quickly with increasing altitude in the centre of habitats compared with the edge, and where water was present compared with where water was absent. We suggest that altitude may limit distribution independent of habitat, and thus is an important factor to take into account, in combination with habitat, when designing mammalian conservation strategies

A novel approach to welfare interventions in problem multi-cat households

BackgroundThousands of injured, stray and relinquished cats are received at the RSPCA Greater Manchester Animal Hospital each year. A significant and challenging proportion of these cats are confiscated from multicat households by RSPCA Inspectors, due to the owners’ inability to care for them. These households share many characteristics of animal hoarding, including poor owner compliance with suggested welfare improvements and recidivism. The relatively poor adoption potential of animals from such households are a perennial problem for the charity.The aim of this study was to determine if offering female cat neutering assistance to multi-cat owners significantly improved colony welfare.ResultsTen multicat households with a history of public complaint to the RSPCA were recruited. An RSPCA veterinary surgeon (VS) initially assessed the overall welfare of each household’s cat population, individual cat welfare and the living environment. All entire female cats aged over 8 weeks were neutered and basic animal care education provided. Follow up visits were completed two and 12 months later to reassess welfare parameters and population numbers.The total number of cats was 176 across ten households (range 7–33, median 16). All owners consented to having all entire female cats spayed. At the first visit, mean individual cat welfare scores ranged from 5.4–8.7/ 16 across the 10 households, where 16 represented best possible welfare.Overall household mean welfare scores were significantly improved at both the 2 month and 12 month revisits (p = 0.011 and p = 0.01 respectively) when compared to the initial visits. By the end of the study period, three out of the ten households had voluntarily relinquished all of their cats, and overall there was a 40% reduction in the number of cats.ConclusionsAnimal hoarding has previously been an intractable welfare concern with little evidence informing intervention techniques. These results show that positive veterinary engagement on site, focused on preventative care and population control, can yield significant improvement in welfare scoring systems in relatively short timescales. Promptly collecting and neutering all female cats at a site, combined with advice and support, show promise in improving welfare

A retrospective study of pyometra at five RSPCA hospitals in the United Kingdom: 1,728 cases from 2006-2011

A retrospective cross-sectional study was used to analyse pyometra cases at five RSPCA Animal Hospitals across the UK from 2006 to 2011. A total of 1728 cases of pyometra were recovered from a female dog outpatient caseload of 78,469 animals, giving a total prevalence of 2.2 per cent over the study period. There was an annual increase in the incidence of pyometra within the population, while elective ovariohysterectomy caseload has declined. There were variations in breed and age at presentation. Bullmastiffs (P<0.0001), golden retrievers (P=0.001) and dogue de Bordeaux (P=0.008) were over-represented in the pyometra population when compared with the female dog outpatient caseload. Mean age at presentation was 7.7 years. Some breeds presented at a significantly lower age, including dogue de Bordeaux (mean age 3.3 years) and bullmastiffs (mean age 5.4 years), while others presented as older dogs, including Yorkshire terriers (mean age 9.4 years) and border collies (mean age 10.3 years). Surgical mortality rate at the Greater Manchester Animal Hospital was 3.2 per cent. Pyometra is of significant welfare concern, and also has cost implications, particularly in charity practice. These results serve to highlight this condition so that future change in charity practice caseload can be anticipated and strategies can be directed to improve animal welfare

Preliminary Results of American Eel Sampling Efforts in Gulf of Mexico Drainages of Texas

American Eel Anguilla rostrata has a unique and complex life history that is fairly well-studied on the eastern coast of the United States, but few studies have been done on Gulf of Mexico drainages. To inform conservation and management decisions, efforts to better understand the population structure, seasonal dynamics, and life history of American Eel are underway. The primary objectives of our efforts are to assess the current and historical distribution and abundance, habitat use, movement patterns, parasite occurrence, diet and population structure of American Eel across all life stages in Gulf of Mexico drainages of Texas.Texas State Wildlife Grant Program grants T-173-R-1 and T-172-R-1 in cooperation with the U.S. Fish and Wildlife Service, Wildlife and Sport Fish Restoration ProgramIntegrative Biolog

Demographics and economic burden of un-owned cats and dogs in the UK: results of a 2010 census

Background The population of dogs and cats passing through rescue shelters may be subject to compromised welfare and increased susceptibility to disease. Little information exists to describe this population, its dynamics and associated management practices. The aim of this study was to carry out a census of un-owned cats and dogs in the UK in 2010, and to document the origins, destinations, husbandry and costs associated with the care of these animals. Results A sampling frame was constructed by searching the databases of publicly registered charities for England, Scotland and Wales, registers of breed rescues, and by internet searches of animal welfare websites. Overall, 2,352 contacts for 1,380 organisations were identified. All were sent a postal questionnaire asking for data on the number of dogs and cats housed, their origins and eventual outcomes, and details of husbandry between January 1st and December 31st 2010. For those which were registered charities (595), financial records were also obtained. A response rate of 38.8% was obtained. Overall, in 2010, 89,571 dogs and 156,826 cats entered the care of the participating organisations. Approximately half of these animals were relinquished by their owners. Other origins included being found as strays or confiscated for welfare purposes. Seventy-five per cent of dogs and 77.1% of cats were rehomed. The next most common outcome was euthanasia, accounting for 10.4% of dogs and 13.2% cats. For dogs and cats, 44.3% and 62% of participants respectively reported having a waiting list, which frequently exceeded the actual capacity of the facility. Over 19,000 people were involved in the care of these animals, on a paid or voluntary basis. Financial records were available for 519/595 (87.2%) of the registered charities, and their total expenditure in 2010 was £340 million. Conclusions This study showed that a large number of animals become un-owned each year, which could have considerable implications for their welfare. Despite the resources expended, demand still exceeds capacity for many organisations, and a substantial number of both cats and dogs are euthanased, suggesting that further understanding of how and why these animals become un-owned is essential in order to target interventions

Evaluating the role of surgical sterilisation in canine rabies control: A systematic review of impact and outcomes

© 2020 Collinson et al. Current recommendations for the elimination of canine-mediated human rabies focus on mass dog vaccination as the most feasible and cost-effective strategy. However, attempts to control rabies are often combined with canine surgical sterilisation programmes. The added value of sterilisation is widely debated. A systematic review was undertaken to compare the outcomes and impact of vaccination and sterilisation programmes with vaccination only programmes. A systematic search of three electronic databases (CAB Abstracts, Med-line and Global Health) and grey literature was performed. From 8696 abstracts found, 5554 unique studies were identified, and 16 studies met the inclusion criteria. Eight described vaccination only programmes and eight described vaccination and sterilisation programmes. Indicators of impact measured were dog bites and/or doses of post-exposure prophylaxis administered; numbers of dog and/or human rabies cases; dog population demographic changes; changes in health and welfare of dogs, and indicators related to human behaviour change. The studies were contextually very diverse, programmes being implemented were complex, and there was variation in measurement and reporting of key indicators. There-fore, it was difficult to compare the two types of intervention, and impossible to make an evaluation of the role of sterilisation, using this evidence. Given the large number of vaccination and sterilisation programmes conducted globally, the lack of studies available for review highlights a gap in data collection or reporting, essential for impact assessment. There are several knowledge gaps concerning the impact of the sterilisation component alone, as well as subsequent effects on rabies transmission and control. Prospective studies comparing the outcomes and impact of the two interventions would be required in order to establish any additional contribution of sterilisation, as well as the underlying mechanisms driving any changes. In the absence of such evidence, the priority for rabies control objectives should be implementation of mass vaccination, as currently recommended by the World Health Organisation

Low Velocity Airdrop Tests of an X-38 Backup Parachute Design

The NASA Johnson Space Center's X-38 program designed a new backup parachute system to recover the 25,000 lb X-38 prototype for the Crew Return Vehicle spacecraft. Due to weight and cost constraints, the main backup parachute design incorporated rapid and low cost fabrication techniques using off-the-shelf materials. Near the vent, the canopy was constructed of continuous ribbons, to provide more damage tolerance. The remainder of the canopy was a constructed with a continuous ringslot design. After cancellation of the X-38 program, the parachute design was resized, built, and drop tested for Natick Soldiers Center's Low Velocity Air Drop (LVAD) program to deliver cargo loads up to 22,000 lbs from altitudes as low as 500 feet above the ground. Drop tests results showed that the 500-foot LVAD parachute deployment conditions cause severe skirt inversion and inflation problems for large parachutes. The bag strip occurred at a high angle of attack, causing skirt inversion before the parachute could inflate. The addition of a short reefing line prevented the skirt inversion. Using a lower porosity in the vent area, than is normally used in large parachutes, improved inflation. The drop testing demonstrated that the parachute design could be refined to meet the requirements for the 500-foot LVAD mission

Radioligand binding analysis of α₂ adrenoceptors with [¹¹C]yohimbine in brain in vivo:Extended Inhibition Plot correction for plasma protein binding

Abstract We describe a novel method of kinetic analysis of radioligand binding to neuroreceptors in brain in vivo, here applied to noradrenaline receptors in rat brain. The method uses positron emission tomography (PET) of [11C]yohimbine binding in brain to quantify the density and affinity of α 2 adrenoceptors under condition of changing radioligand binding to plasma proteins. We obtained dynamic PET recordings from brain of Spraque Dawley rats at baseline, followed by pharmacological challenge with unlabeled yohimbine (0.3 mg/kg). The challenge with unlabeled ligand failed to diminish radioligand accumulation in brain tissue, due to the blocking of radioligand binding to plasma proteins that elevated the free fractions of the radioligand in plasma. We devised a method that graphically resolved the masking of unlabeled ligand binding by the increase of radioligand free fractions in plasma. The Extended Inhibition Plot introduced here yielded an estimate of the volume of distribution of non-displaceable ligand in brain tissue that increased with the increase of the free fraction of the radioligand in plasma. The resulting binding potentials of the radioligand declined by 50–60% in the presence of unlabeled ligand. The kinetic unmasking of inhibited binding reflected in the increase of the reference volume of distribution yielded estimates of receptor saturation consistent with the binding of unlabeled ligand
