On Technology Transfer to an Asymmetric Cournot Duopoly

This note studies the transfer of a cost-reducing innovation from an independent patent-holder to an asymmetric Cournot duopoly that has different unit costs of production. It is found that royalty licensing can be superior to fixed-fee licensing for the independent patent-holder.Cournot duopoly

Extending boundaries: young people as action researchers

Action research is generally undertaken by adults as a process of systematic action planning and enquiry which can lead to improvements in aspects of their professional practices. This article challenges and extends conventional understanding of action research to show how young people, between the ages of 10 and 17, can interrogate and improve their own practices – both individually and collectively. Brief accounts of four case studies – three British and one South African – are presented, along the lines of a patchwork narrative. Each ‘patch’ in turn contributes to the later collation of a theme and ideas that ‘stitch’ the studies together

What does the child protection movement teach us about the role of the mandated reporter of abuse?

Requiring veterinarians to report suspected animal abuse faces many of the same issues, concerns and hurdles once faced by the child protection movement. The history of child protection may hence provide a strategic model for progress in animal protection. Being able to anticipate the hurdles will help prepare us to overcome them

The benefits to the Australian Pig meat industry from an increase in demand for a hypothetical low cholesterol pork product

This is the third of a series of papers examining the potential economic effects from the introduction of a hypothetical low cholesterol pork product into the Australian market. Here, a newly updated pig meat model reported by Griffith et al. (2010) is used to model the industry wide impacts of the Bellhouse et al. (2010) survey results on consumer willingness to pay for this new pork product. Six different scenarios are examined that are combinations of a 10, 20 or 30 per cent increase in consumer demand, with and without a 10 per cent increase in the costs of producing the more valuable pork. The simulation results for the various scenarios indicate total annual industry benefits of some $450m for an increase in aggregate willingness to pay of 30 per cent and no cost increase, down to$88m for an increase in aggregate willingness to pay of 10 per cent and a 10 per cent cost increase. Australian consumers receive about 80 per cent of total benefits, pork producers receive about 7-8 per cent and all other market participants together receive about 12-13 per cent. These values provide a guide to the size of the annual investment that could be justified by pork producers to produce a pig that is low in cholesterol.cholesterol, pork, Australia, consumer willingness to pay, demand, Agribusiness, Demand and Price Analysis, Environmental Economics and Policy, Farm Management, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries, Production Economics,

Old model, new problem: when should you update a model and what happens when you do?

This paper is a summary of some of the considerations involved in applying an existing model to a new problem, in particular in deciding whether to update or not, and some of the issues involved in interpreting the output from the new application. Thus where you start from does influence where you end up. Both change in total surplus and to a lesser extent the distribution of this change in total surplus across sectors, depends on the price and quantity data which is used to define the initial equilibrium, even if elasticity values are the same. So careful consideration should be given to whether an existing model should be updated because updating a model does matter. The final point to restate is that consumers of pig meat end up being the winners from either cost saving technology at the farm level or new product development or advertising campaigns at the retail level. Even for new technology implemented at the farm level, producers only receive about 20 per cent of the total benefits. These issues are discussed in detail in Mounter et al. (2005a, 2005b). Therefore in relation to the new problem outlined above, we now have a modelling framework available for the task that has been tested in a number of different ways and that now reflects current industry structure and size. It should be a more appropriate framework than the original that was described in the papers by Mounter et al. (2004, 2005a, 2005b).new model, old model, decision making, change in total surplus, updating a model, new technologies, pork, industry structure, industry size, Agribusiness, Agricultural Finance, Environmental Economics and Policy, Farm Management, Industrial Organization, Institutional and Behavioral Economics, Livestock Production/Industries, Marketing,

Developing a predictive tool for psychological well-being among Chinese adolescents in the presence of missing data

<p>Abstract</p> <p>Background</p> <p>Multi-dimensional behavioral rating scales like the CBCL and YSR are available for diagnosing psychosocial maladjustment in adolescents, but these are unsuitable for large-scale usage since they are time-consuming and their many sensitive questions often lead to missing data. This research applies multiple imputation to tackle the effects of missing data in order to develop a simple questionnaire-based predictive instrument for psychosocial maladjustment.</p> <p>Methods</p> <p>Questionnaires from 2919 Chinese sixth graders in 21 schools were collected, but 86% of the students were missing one or more of the variables for analysis. Fifteen (10 training, 5 validation) samples were imputed using multivariate imputation chain equations. A ten-variable instrument was constructed by applying stepwise variable selection algorithms to the training samples, and its predictive performance was evaluated on the validation samples.</p> <p>Results</p> <p>The instrument had an AUC of 0.75 (95% CI: 0.73 to 0.78) and a calibration slope of 0.98 (95% CI: 0.86 to 1.09). The prevalence of psychosocial maladjustment was 18%. If a score of > 1 was used to define a negative test, then 80% of the students would be classified as negative. The resulting test had a diagnostic odds ratio of 5.64 (95% CI: 4.39 to 7.24), with negative and positive predictive values of 88% and 43%, and negative and positive likelihood ratios of 0.61 and 3.41, respectively.</p> <p>Conclusions</p> <p>Multiple imputation together with internal validation provided a simple method for deriving a predictive instrument in the presence of missing data. The instrument's high negative predictive value implies that in populations with similar prevalences of psychosocial maladjustment test-negative students can be confidently excluded as being normal, thus saving 80% of the resources for confirmatory psychological testing.</p

StarCraft 2 Replay Analysis

This data was used in Thompson et al. (2013). We aggregated screen movements into screen-fixations using a Salvucci &amp; Goldberg (2000) dispersion-threshold algorithm, and defined Perception Action Cycles (PACs) as fixations with at least one action. Time is recorded in terms of timestamps in the StarCraft 2 replay file. When the game is played on \u27faster\u27, 1 real-time second is equivalent to roughly 88.5 timestamps. A list of possible game actions is discussed in Thompson, Blair, Chen, &amp; Henrey (2013). Skip league conditional inference forest classification was used (Bronze-Gold;Silver-Platinum;Gold-Diamond;Platinum-Masters;Diamond-Professional) to show changing patterns of variable importance with skill.

The Psychology of Animal Cruelty: An Introduction to the Special Issue

As guest editors for Psychology, Crime, and Law, it is with great pleasure that we present this Special Issue, “The Psychology of Animal Cruelty”. In this introductory article, we offer broad insights into what we think to be the importance of studying this type of offending behavior. This forms the basis and justification for putting together this compilation of research, which spans three continents, that is diverse in theory application, method and research design. We provide brief synopses for the articles included in this issue. These articles cover the social and psychological factors related to child and adult perpetrators, offence heterogeneity (e.g., varying levels of abuse severity), victim characteristics, amongst other features of animal cruelty. We also offer a commentary on where the research can go next, identifying specific gaps in the existing literature. We conclude that there is an abundance of extant, related research that we can draw upon to inform future studies (e.g., implicit theories, scripts/schemas, dynamic risk factors) and clinical practice
