A brief account of the present status of Precision Agriculture (PA) in Australia is presented, and areas of opportunity in the grains, sugar and wine industries are identified. In particular, these relate to the use of spatially-distributed experimentation to fine-tune management so as to achieve production efficiencies, reduced risk of environmental impact and enhanced food security, and the management of crop quality through selective harvesting and product streaming. The latter may be an important avenue by which farmers can take a more active role in the off-farm part of agricultural value chains. The important role of grower groups in facilitating PA adoption is also discussed.

This study aimed to assess the achievement level of community empowerment in realizing food security. The result was expected to reveal a model of community empowerment, particularly farmer community institution as an attempt to attain food security. Survey was employed as the research method that involved the farmers (farmer groups) as the members of Food Barn for the Village Community (Lumbung Pangan Masyarakat Desa/LPMD). Technique of rapid rural appraisal was selected in the form of quantitative and qualitative analysis. Preliminary survey in study area was carried out to obtain the characteristic and status of food security; and to mapping the potential and role of Lumbung Pangan Masyarakat Desa in the process of community empowerment. Subsequently, study and analysis was done based on the survey. The results demonstrated the active role of stakeholders (A-B-G-C) was significant in supporting the farmer institution (food barn). The economic and social aspects were also evidenced to have important role in enhancing the farmer community empowerment. This model is called social engine for rural community and local institution, particularly to attain the regional food security.

Unrealistic Expectations

AbstractThe respect for the situation of victims of crime has risen immensely over the last couple of decades. Consequently the importance of the victim at trial has changed radically. First, the victim deserves protection from secondary victimisation in the course of prosecution; secondly, the victim is attributed a more active role compared to the mere role as a witness for the prosecution. The traditional idea of a "public" prosecution, whereby the prosecutor as a state official mediates the victim, is considerably challenged if the victim acts as a "private" prosecutor. The article analyses recent developments both in German and international criminal procedural law concerning "victim participation" and contrasts this development with the interests and expectations voiced by victims of crime. It is held that criminal procedure should not be overburdened with unrealistic expectations as contributing to an overall healing process and stay focused on its main aim: determining the guilt of the alleged offender.

Epigenetic Processes

Environmental stresses such as salinity, drought, heat, freezing, heavy metal and even pathogen infections seriously threaten the growth and yield of important cereal crops including wheat and barley. There is growing evidence indicating that plants employ sophisticated epigenetic mechanisms to fine-tune their responses to environmental stresses. Here, we provide an overview of recent developments in understanding the epigenetic processes and elements—such as DNA methylation, histone modification, chromatin remodeling, and non-coding RNAs—involved in plant responses to abiotic and biotic stresses in wheat and barley. Potentials of exploiting epigenetic variation for the improvement of wheat and barley are discussed.

Africa's food security may be at risk if food production does not increase, especially given that by 2023, African food market will more than triple in demand by moving from $300 billion to $1 trillion. However, country-specific interventions have not provided the desired impact towards guaranteeing food security. Across different agricultural value chains, wastages due to lack of access to markets, poor storage, lack of logistics, transport and power infrastructure, among several others. There is, however, the possibility of strengthening these value chains with the right technology deployment. This requires significant investment, which is most effective using collaborative stakeholder approach. The private sector has shown signs of resilience in investing in agriculture by finding the right business models such as digital platforms which are in themselves scalable businesses. Through an interrogative literature review and analysis of case studies, this chapter explores the role of digital platforms in enhancing diverse agricultural value chains across Africa.

A value chain consists of the actors (private and public, including service providers) and the sequence of value-adding activities involved in bringing a product from production to the end-consumer. In agriculture they can be thought of as a “farm-to-fork” set of inputs, processes and flows. Agricultural businesses in developing countries offer an opportunity for market based economic development that creates benefits throughout value chains. Sustainable development in agricultural value chains of emerging economies could be of high relevance of Sustainable Precision Agriculture.

Recent developments in the provision and funding of industry training in New Zealand have provided substantial challenges for Industry Training Organisations. This article focuses upon the role that they are expected to play in supporting the Labour-led Coalition’s Economic Transformation (ET) agenda, and explores some of the challenges created. A major aim of the ET agenda is to produce globally competitive firms by better directing the government investment in education and training and in research, science and technology. In this context, Industry Training Organisations are expected to play an increasingly active role in driving the government’s investment in industry training. This article considers some of the barriers and challenges they face in meeting these new government expectations.

Human Erythrocyte Ghost

Spectrin is a membrane associated protein most of which properties have been tentatively elucidated. A main role of the protein has been assumed to give a supporting structure to inside of the membrane. As reported previously, however, the isolated spectrin molecule underwent self assemble to form such as fibrous, meshwork, dispersed or aggregated arrangements depending upon the buffer suspended and was suggested to play an active role in the membrane conformational changes. In this study, the role of spectrin and actin was examined in terms of the molecular arrangements on the erythrocyte membrane surface with correlation to the functional states of the ghosts.Human erythrocyte ghosts were prepared from either freshly drawn or stocked bank blood by the method of Dodge et al with a slight modification as described before. Anti-spectrin antibody was raised against rabbit by injection of purified spectrin and partially purified.

Hardened Cement Paste

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.

Gene Regulatory

Gene regulatory information can be inherited between generations in a phenomenon termed transgenerational epigenetic inheritance (TEI). While examples of TEI in many animals accumulate, the nematode Caenorhabditis elegans has proven particularly useful in investigating the underlying molecular mechanisms of this phenomenon. In C. elegans and other animals, the modification of histone proteins has emerged as a potential carrier and effector of transgenerational epigenetic information. In this review, we explore the contribution of histone modifications to TEI in C. elegans. We describe the role of repressive histone marks, histone methyltransferases, and associated chromatin factors in heritable gene silencing, and discuss recent developments and unanswered questions in how these factors integrate with other known TEI mechanisms. We also review the transgenerational effects of the manipulation of histone modifications on germline health and longevity.
