Open to Ideas: Information flows from Dairy Directions to Dairy Farmers

The ‘openness’ of farming systems that is the focus of this paper is ‘open to information’, in particular the way that new information from the farming systems research project, Dairy Directions, flows from research outputs to dairy farmers. Dairy Directions is a multidisciplinary research activity centred on a steering group of interested parties, mostly farmers, scientists and economists, but also drawing on extension agents, natural resource managers, water service providers, community service providers and public policy participants. The core general research question of Dairy Directions is ‘What options do farmers running different dairy farming systems have to achieve their goals in an uncertain future?’ The goals analysed by the project are predominantly economic and financial – maintaining or increasing profit and cash flow, growing wealth, managing risk, preparing for succession and balancing the dairy work-life balance. Their uncertain future encompasses variability in prices, as well as the natural environment and the policy setting.Farm Management,

Point-contact tunneling spectroscopy measurement of Cux_xTiSe2_2: disorder-enhanced Coulomb effects

We performed point-contact spectroscopy tunneling measurements on Cu$_x$TiSe$_2$ bulk with $x=0.02$ and $0.06$ at temperatures ranging from $T=4-40$ K and observe a suppression in the density of states around zero-bias that we attribute to enhanced Coulomb interactions due to disorder. We find that the correlation gap associated with this suppression is related to the zero-temperature resistivity. We use our results to estimate the disorder-free transition temperature and find that the clean limit $T_{c0}$ is close to the experimentally observed $T_c$.Comment: 4 pages, 4 figure

Home-based end of life care for children and their families: a systematic scoping review and narrative synthesis

AbstractProblem: There is a growing international drive to deliver children’s palliative care services closer to home. Families should have choice of where end of life (EOL) care is provided with home as one option. This review aims to establish the current international evidence base relating to children’s EOL care at home.Eligibility Criteria: A systematic scoping review was conducted in accordance with PRISMA-ScR reporting guidelines. Seven databases were searched to identify papers published between 2000-2018. Eligibility criteria included papers reporting children’s EOL care with specific relation to: home being the preferred place of death; services providing EOL care at home; family experiences of receiving support when their child died at home and professionals’ experiences of delivering this care.Sample: Twenty-three papers met the eligibility criteria and were included in the review.Results: Engagement of families in EOL care planning discussions was identified as a key factor to facilitate choice of setting. Consistent themes from the data suggest that providing access to care in the home 24/7 by a team of professionals with specialist paediatric palliative care knowledge is an essential aspect of any model of home-based EOL care.Discussion and Application to Practice: This is the first comprehensive review of home-based EOL care for children which offers a valuable contribution to policy, practice and research. The evidence mapped and synthesised in this review can inform the development of services to facilitate the provision of EOL care at home in line with the unique wishes and needs of children and families

An economic analysis of options for utilising additional land on a high rainfall Gippsland dairy farm

A range of options for utilising additional land on a dairy farm in the high rainfall area of Gippsland were analysed. The aim was to determine if additional land may assist the owners/operators in maintaining or increasing profit in the medium term (5-10 years). Historical trends have been towards fewer, larger, more intensive enterprises, and this project studies the value of additional land in continuing or altering this trend. A case study farm and spreadsheet modelling approach was used to examine these issues. Five different uses for additional land were identified by an expert steering committee, and were compared to the base farm system over a 10-year development period. The results suggest that expanding the milking area by purchasing additional land without a significant increase in herd size (2A) increased annual operating profit by approximately $70,000/year without increasing variability when compared to the base farm system. This was the only option examined to earn a high enough internal rate of return on additional capital investment to justify the investment without capital gains. Additional milking area with a substantial increase in stocking rate (2C) significantly reduced annual operating profit (by approximately$70,000/year) and notably increased the variability of these returns. The purchase of an outblock for conserved fodder production improved profitability, but would require some capital gains to be an attractive option on profit measures alone. The most appropriate changes to dairy farm businesses in response to changes in the operating environment will vary from farm to farm. The analysis indicated that simple following previous industry trends may not be appropriate on many farms. Optimising the amount of home grown feed and efficiently using purchased supplements are important, particularly if the milk produced is subject to the fluctuations of an export milk price.Farm Management,

Advertising Practioners’ Educational Prerequisites: Differentiating The Needs Of Creatives From Non Creatives

Singapore‘s advertising industry is one of the clusters identified as an important growth area in the country‘s creative economy. The growth of the media industry, in particular the advertising industry has thus added urgency to call for higher institutions in Singapore to help nurture a pool of creative manpower by providing a well-rounded and comprehensive relevant education on advertising. An effective education policy is therefore a prime instrument in facilitating developments in this industry. A joint research initiative was conducted with the participation of a few advertising companies in Singapore. These included both creative agencies as well as media buying firms. The research served to examine the formal education needs of both creative and non-creative advertising professionals. From the study, we found that the education requirements for creative and non-creative education are similar, but not identical. Industry practitioners viewed that practical exposure are important for both groups of professionals. However, for creative education especially, this aspect took an additional importance as the most notable and common responses were the invitation of industry practitioners to conduct classes, undertaking real life projects and obtaining a global perspective via the engagement of renowned international advertising professionals or going for overseas internships. The study served as a springboard to a more exhaustive study in the advertising industry within Singapore as well as in comparison over a cross-section of countries, providing an insight into trends, different supporting factors and conditions for creativity in relation to the advertising industry

Developing a representative driving cycle for paratransit that reflects measured data transients: case study in Stellenbosch, South Africa

Paratransit plays a critical role in meeting transportation needs in many cities in sub-Saharan Africa (SSA). However, it faces deep issues related to pollution, congestion, and safety. Understanding the driving patterns of paratransit in SSA can provide valuable insights into the transportation needs in the region, which is particularly relevant nowadays given the increasing focus on sustainable transportation solutions in Africa. Representative driving cycles, which provide a realistic simulation of the driving conditions a vehicle is likely to encounter, are key to framing policies for effective transportation management, vehicle design, and urban and regional planning. However, cycle development has been limited in SSA due to a lack of data and standardized testing procedures. This study develops a representative driving cycle using GPS data gathered on paratransit vehicles traveling around Stellenbosch, South Africa, providing a benchmark for evaluation and a platform for further research and testing in SSA’s dominant transport industry. A novel time series shape-based clustering methodology is employed that combines dynamic time warping and mixed integer programming to cluster micro-trips of varying length based on their time series shapes. Representative micro-trips from each cluster are stitched together with a maximum likelihood approach to curate the final cycle. By including transients from the measured data in cycle development, this novel approach to cycle development is particularly suited for capturing the notoriously unconventional and aggressive driving style of paratransit. The constructed cycle and several international cycles are assessed against the measured database on the basis of eight characteristic kinematic parameters. The constructed cycle emerges as the most fitting choice to represent paratransit operating conditions, with an average deviance of 3.65% across the parameters, compared to deviations of 23%–34% for the international cycles

6C radio galaxies at z~1: The influence of radio power on the alignment effect

Powerful radio galaxies often display enhanced optical/UV continuum emission and extended emission line regions, elongated and aligned with the radio jet axis. The expansion of the radio source strongly affects the gas clouds in the surrounding IGM, and the kinematic and ionization properties of the extended emission line regions display considerable variation over the lifetime of individual sources, as well as with cosmic epoch. We present the results of deep rest-frame UV and optical imaging and UV spectroscopy of high redshift 6C radio galaxies. The interdependence of the host galaxy and radio source properties are discussed, considering: (i) the relative contribution of shocks associated with the expanding radio source to the observed emission line gas kinematics, and their effect on the ionization state of the gas; (ii) the similarities and differences between the morphologies of the host galaxies and aligned emission for a range of radio source powers; and (iii) the influence of radio power on the strength of the observed alignment effect.Comment: LaTeX, 6 pages, 5 figures, Elsevier Science format.
