Paddock selection is an important component of grazing management and is based on either some estimate of pasture mass (cover) or the interval since last grazing for each paddock. Obtaining estimates of cover to guide grazing management can be a time consuming task. A value proposition could assist farmers in deciding whether to invest resources in obtaining such information. A farm-scale simulation exercise was designed to estimate the effect of three levels of knowledge of individual paddock cover on profitability: 1) "perfect knowledge", where cover per paddock is known with perfect accuracy, 2) "imperfect knowledge", where cover per paddock is estimated with an average error of 15%, 3) "low knowledge", where cover is not known, and paddocks are selected based on longest time since last grazing. Grazing management based on imperfect knowledge increased farm operating profit by approximately $385/ha compared with low knowledge, while perfect knowledge added a further $140/ha. The main driver of these results is the level of accuracy in daily feed allocation, which increases with improving knowledge of pasture availability. This allows feed supply and demand to be better matched, resulting in less incidence of under- and over-feeding, higher milk production, and more optimal post-grazing residuals to maximise pasture regrowth.

Paddock selection is an important component of grazing management and is based on either an estimate of herbage mass, or the interval since last grazing for each paddock. Obtaining estimates of herbage mass to guide grazing management can be a time consuming task. A value proposition could therefore assist farmers in deciding whether to invest resources in obtaining such information. A farm-scale simulation exercise was designed to estimate the effect of three levels of knowledge of individual paddock herbage mass on profitability of two typical pasture-based dairy systems in New Zealand; a medium input system stocked at 3.2 Friesian-Jersey cross bred cows/ha with ~15% imported feed, and a high input system stocked at 4.5 Friesian cows/ha with ~40% imported feed. The three levels of knowledge were: (1) ‘perfect knowledge’, where herbage mass per paddock is known with perfect accuracy, (2) ‘imperfect knowledge’, where herbage mass per paddock is estimated with an average error of 15%, (3) ‘low knowledge’, where herbage mass is not known, and paddocks are selected based on longest time since last grazing. In both systems, grazing management based on imperfect knowledge increased farm operating profit by ~NZ$385/ha at a milk price of NZ$6.33/kg milksolids (fat + protein) compared with low knowledge. Perfect knowledge added a further NZ$155/ha to profit. The main driver of these results is the level of accuracy in daily feed allocation, which increases with improved knowledge of herbage availability. This allows feed supply and demand to be better matched, resulting in less incidence of under- and over-feeding, higher milk production, and more optimal post-grazing residual herbage mass to maximise herbage regrowth.

The five freedoms and, more recently, the five domains of animal welfare provide internationally recognised frameworks to evaluate animal welfare practices which recognise both the physical and mental wellbeing needs of animals, providing a balanced view of their ability to cope in their environment. Whilst there are many techniques to measure animal welfare, the challenge lies with how best to align these with future changes in definitions and expectations, advances in science, legislative requirements, and technology improvements. Furthermore, enforcement of current animal welfare legislation in relation to livestock in Australia and the reliance on self-audits for accreditation schemes, challenges our ability to objectively measure animal welfare. On-animal sensors have enormous potential to address animal welfare concerns and assist with legislative compliance, through continuous measurement and monitoring of an animal’s behavioural state and location being reflective of their wellbeing. As reliable animal welfare measures evolve and the cost of on-animal sensors reduce, technology adoption will increase as the benefits across the supply chain are realised. Future adoption of on-animal sensors by producers will primarily depend on a value proposition for their business being clear; algorithm development to ensure measures are valid and reliable; increases in producer knowledge, willingness, and trust in data governance; and improvements in data transmission and connectivity.

The rapidly increasing significance of cyberspace and the corresponding use of new cyberspace technologies are seen in private, public, and nonprofit organizations across the globe. However, along with the abundant organizational advantages of operating in cyberspace, it also creates vulnerabilities such as the possibility of cyberattacks which can erode value. In light of these current realities, we propose a value creation agenda for organizations that operate in cyberspace. We suggest that when organizations effectively manage the risks associated with cyberattacks and continue to attain benefits from cyberspace, there is a positive contribution toward organizational value.

Die fortschreitende Digitalisierung führt zu neuen und konvergierenden Produkt- und Dienstleistungen und effizienteren Prozessen. In Verbindung mit einem Wandel der Bedürfnisse führt sie darüber hinaus auch zu einem veränderten Nutzerverhalten und Nutzenverständnis der Kunden. Zur flexiblen und schnellen Umsetzung von passgenau individualisierten, oft branchenübergreifenden Wertangeboten und der Absicherung des Kundenzugangs wird es zukünftig wettbewerbsentscheidend sein, sich im richtigen Business Ecosystem – also der Gruppe von Akteuren die interagieren müssen, um ein entsprechendes Wertangebot zu realisieren und den entsprechenden Kundenzugang haben – zu bewegen und dieses mitzugestalten. Der Beitrag beschreibt das grundsätzliche Vorgehen zur Identifizierung und Auswahl relevanter Business Ecosystems sowie deren strategische und operative Einbindung in ein Unternehmen.   The ongoing digitization leads to new and converging product benefits and more efficient processes. In connection with a change in needs it also leads to a change in user behaviour and understanding of the benefits for customers. For the flexible and fast implementation of customized, individualized, often cross-industry value propositions and the safeguarding of access to customers, it will be crucial in the future to act and help to shape the relevant business ecosystems (group of actors that need to interact in order to realize a value proposition or to have access to customers). The article describes the basic procedure for identifying and selecting relevant business ecosystems and their strategic and operational integration into a company.

Point Of Care Tests

IntroductionSexually Transmitted Infections (STIs), including Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), continue to be a global health problem, with the majority of the disease burden in Low and Middle Income Countries. This could in part be addressed through increased access to rapid point-of-care-tests (POCTs) for infection detection and appropriate clinical management. Guidelines and criteria for the development of STI POCTs have been established, and several POCTs for CT and NG have been brought to market. Yet even those diagnostics with good evidence of clinical effectiveness often fail to be implemented and adopted into routine care. Here we review the current literature for test development and implementation alongside studies of how the Cepheid CT/NG GeneXpert POCT has been utilised in different healthcare settings, to develop a value proposition for CT/NG POCT adoption.MethodsWe review whether the Cepheid CT/NG GeneXpert fulfil the (RE)ASSURED and Target Product Profile (TPP) criteria, and present published literature reporting on the test’s implementation, to demonstrate its range of values in different settings and to a variety of stakeholders. This information is then applied to the value proposition for laboratory medicine, to form the basis of a value proposition for a CT/NG POCT. ResultsThe Cepheid CT/NG GeneXpert did not fulfil all (RE)ASSURED or TPP criteria, however, studies of test implementation showed multiple stakeholder values for the use of the test across various healthcare settings and geographic locations. The majority of values identified were setting specific. Sexual health services and outreach services had the least overlap in values, whereas General Practice and other non-sexual health specialist services served as a “bridge” between the two.ConclusionWe recommend that those wishing to improve CT/NG diagnosis be supported to identify the values most relevant to their settings and context, and prioritise implementation of those tests most closely aligned with those values.

Measurement of high voltage AC, DC and Impulses on a laboratory scale using expensive measuring instruments. In addition, the measurements taken are at a voltage level of 15 KV. Integrated measurement of high voltage AC, DC and Impulses for 15 KV voltage levels using sign transformers has never been done. Whereas high voltage generation using a sign transformer is only able to generate voltage up to 15 KV voltage only. For that we need a voltage measuring device that is able to measure up to a voltage of 15 KV, and does not require expensive costs. In this Final Project, a high voltage monitoring module for impulse high voltage generator module will be designed using visual studio c #. The results of monitoring the high voltage generator module on the C # visual studio form successfully went well. The voltage test performed produces a value close to the actual value with an average error of 0.01 volts. Unfortunately this test is still not perfect because it is still susceptible to noise so that the measurement process is often interrupted.

High competition in the markets of goods and services makes it urgent to improve the efficiencyof the use of production assets by the enterprises. One of the possible ways to solve the problem is joint use of the assets by different subjects. The use of this mechanism in the various branches grows rapidly in the last decade due to the opportunities for aggregation of supply and demand and automated contracting provided by the modern digital technologies. The basis for production asset management systems based on sharing is a mathematical model that allows determining the optimal modes of asset use in terms of their utilization, reducing the total cost of ownership and obtaining additional operating profit. This article considers a mathematical model of a multi-product spatially distributed production system that reflects the features of the activities of machine-building enterprises and assumes the possibility of joint use of their fixed assets. Economic and social criteria for the efficiency of fixed assets sharing are formulated in terms of maximizing the profit of enterprises, minimizing logistics and downtime costs. The optimal modes of joint use of the fixed assets concerning these criteria are investigated. It is shown that the joint use of fixed assets under the certain conditions can significantly improve the efficiency of the operating activities of enterprises.
