Changes in Pasture Growth Rate Due to Fertiliser and Grazing Management

It is imperative that sheep production systems in southern Australia continue to be refined so producers remain financially viable but at the same time the environment is not degraded. As part of a national thrust for development and promotion of better production systems, one research site has been established in Victoria where pastures and animal production are measured together with water and nutrient movement. Results for pasture growth rates over two years are presented here and will be used to develop best industry practice at completion of the project

Maintaining Relationships With Supply Chain Partners: A Case Study

This case study describes efforts of a market leader in the communication infrastructure industry to assess the relationships they have developed with their global supply chain partners.  Changes in the industry have resulted in geographic shifts of existing and potential supply chain suppliers and customers.  In an effort to determine if commitment to customer service has resulted in increased customer satisfaction and loyalty, research was conducted to assess their performance.  The results of this research were compared to previous research to determine if their service program has successfully differentiated them from their competitors

Thundermist Health Center: Extending Pharmaceutical Services To Underserved Patients

This paper describes a not-for-profit healthcare providers strategy to provide its economically disadvantaged patients with access to low cost pharmaceuticals. Initially, an in-house pharmacy was established, supported by a satellite distribution system using a telepharmacy solution to extend medications to its patients at remote sites. New federal legislation which provided access to low cost insurance through Medicare Part D to many of the providers disadvantaged patients, along with state licensing requirements forced the healthcare provider to reassess the economics of its pharmaceutical distribution system and seek other alternatives. Among the alternatives the healthcare provider considered was partnering with for-profit pharmaceutical companies in order to reach their patients

What happens when you tell someone you self-injure? The effects of disclosing NSSI to adults and peers

Background: Non-suicidal self-injury (NSSI) is associated with significant adverse consequences, including increased risk of suicide, and is a growing public health concern. Consequently, facilitating help-seeking in youth who self-injure is an important goal. Although young people who disclose their NSSI typically confide in peers and family, it is unclear how this disclosure and related variables (e.g. support from family and friends, coping behaviours, reasons for living) affect help-seeking over time. The aim of this study was to advance understanding of the impact of disclosure of NSSI by young people and to investigate these effects over time. Methods: A sample of 2637 adolescents completed self-report questionnaires at three time points, one year apart. Results: Of the sample, 526 reported a history of NSSI and 308 of those who self-injured had disclosed their behaviour to someone else, most commonly friends and parents. Conclusions: Overall, we observed that disclosure of NSSI to parents facilitates informal help-seeking, improves coping and reduces suicidality, but that disclosure to peers might reduce perceived social support and encourage NSSI in others. We discuss these findings in light of their clinical and research implications

From Network Interface to Multithreaded Web Applications: A Case Study in Modular Program Verification

Many verifications of realistic software systems are monolithic, in the sense that they define single global invariants over complete system state. More modular proof techniques promise to support reuse of component proofs and even reduce the effort required to verify one concrete system, just as modularity simplifies standard software development. This paper reports on one case study applying modular proof techniques in the Coq proof assistant. To our knowledge, it is the first modular verification certifying a system that combines infrastructure with an application of interest to end users. We assume a nonblocking API for managing TCP networking streams, and on top of that we work our way up to certifying multithreaded, database-backed Web applications. Key verified components include a cooperative threading library and an implementation of a domain-specific language for XML processing. We have deployed our case-study system on mobile robots, where it interfaces with off-the-shelf components for sensing, actuation, and control.National Science Foundation (U.S.) (Grant CCF-1253229)United States.

Optimal discrete stopping times for reliability growth tests

Often, the duration of a reliability growth development test is specified in advance and the decision to terminate or continue testing is conducted at discrete time intervals. These features are normally not captured by reliability growth models. This paper adapts a standard reliability growth model to determine the optimal time for which to plan to terminate testing. The underlying stochastic process is developed from an Order Statistic argument with Bayesian inference used to estimate the number of faults within the design and classical inference procedures used to assess the rate of fault detection. Inference procedures within this framework are explored where it is shown the Maximum Likelihood Estimators possess a small bias and converges to the Minimum Variance Unbiased Estimator after few tests for designs with moderate number of faults. It is shown that the Likelihood function can be bimodal when there is conflict between the observed rate of fault detection and the prior distribution describing the number of faults in the design. An illustrative example is provided

Thermocurrents and their Role in high Q Cavity Performance

Over the past years it became evident that the quality factor of a superconducting cavity is not only determined by its surface preparation procedure, but is also influenced by the way the cavity is cooled down. Moreover, different data sets exists, some of them indicate that a slow cool-down through the critical temperature is favourable while other data states the exact opposite. Even so there where speculations and some models about the role of thermo-currents and flux-pinning, the difference in behaviour remained a mystery. In this paper we will for the first time present a consistent theoretical model which we confirmed by data that describes the role of thermo-currents, driven by temperature gradients and material transitions. We will clearly show how they impact the quality factor of a cavity, discuss our findings, relate it to findings at other labs and develop mitigation strategies which especially addresses the issue of achieving high quality factors of so-called nitrogen doped cavities in horizontal test
