Sorghum Production

There are two major pests of sorghum in Australia, the sorghum midge, Stenodiplosis sorghicola (Coquillett), and the corn earworm, Helicoverpa armigera (Hübner). During the past 10 years the management of these pests has undergone a revolution, due principally to the development of sorghum hybrids with resistance to sorghum midge. Also contributing has been the adoption of a nucleopolyhedrovirus for the management of corn earworm. The practical application of these developments has led to a massive reduction in the use of synthetic insecticides for the management of major pests of sorghum in Australia. These changes have produced immediate economic, environmental and social benefits. Other flow-on benefits include providing flexibility in planting times, the maintenance of beneficial arthropods and utilisation of sorghum as a beneficial arthropod nursery, a reduction in midge populations and a reduction in insecticide resistance development in corn earworm. Future developments in sorghum pest management are discussed.

An experiment was established to determine the effect of different tillage practices, vegetable crop rotations, and pest management strategies on crop yield, plant diseases, pest and beneficial arthropods, weed species changes over time, and soil environmental consequences. This poster describes nitrogen movement from the various treatments over a 3-year rotation. The treatments are: 1) conventional tillage with chemically based IPM; 2) conventional tillage with biologically based IPM; 3) conservation tillage with chemically based IPM; 4) conservation tillage with biologically based IPM; and 5) conventional tillage with no fertilizer or pest management. Mid-season soil analyses with depth showed chemical-fertilized plowed and conservation-tilled treatments with more soil available nitrogen at most depths compared to the biological-based IPM systems (soybean meal was used as a nitrogen source). However, the biological-based systems did supply enough soil nitrogen to produce similar yield results as the chemical-based systems. Less soil nitrate was measured in the 30- to 90-cm depths at harvest from the biological-based systems than chemical-based systems. Conservation-tilled systems had greater nitrate with depth compared to conventional-tilled systems.

Recent Developments

Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management. In this review, we present the most recent developments in pheromone research and its application in the past two decades.

Power Concept

The article focuses on the task of measuring and evaluating a state's soft power. While the soft power concept developed by Joseph Nye is currently widely accepted and used, its theoretical understanding and practical application remains challenging. Both international relations scholars and those responsible for soft power in governmental and non-state agencies are looking for the tools to assess their work and the country's standing in the world in terms of soft power. As the author of the concept and other researchers noted, evaluation and measurement may be difficult due to the number of influencing factors including the use of hard power that can overshadow soft power efforts, and also because soft power efforts can bring results only in a distant period of time. However, in response to the researchers' and policy makers' need to evaluate, measure and compare soft power related parameters, a number of international ratings evolved during the past several years, such as various ratings of soft power, nation brands, countries' reputation and presence. At the same time, such rankings have several weaknesses. First of all, they present mainly the western point of view which focuses on the parameters important for western audiences and may overlook characteristics important for other, non-western cultures. They also may be subjective due to financial reasons. Besides that, while some of the ratings aim to evaluate resources or assets of nations' soft power, other focus on results like influence or reputation. Evaluation of instruments used to enhance a country's soft power and their effectiveness is also important. In many cases, even significant resources of soft power do not guarantee strong positions in this context. Comparing certain countries' positions in different ratings helps to understand a country's standing in terms of soft power, identify strong sides and analyze whether a state's soft power potential transforms into the desired outcomes.

Molecular Aspects

Current and emerging biomedical science efforts are driven by determining how to improve clini-cal outcomes for patients. High-throughput tech-nology has revolutionized the area of transla-tional research, confirming the high complexity and heterogeneity of common diseases, partic-ularly cancer. Therefore, moving from ‘classic’ single-gene-based molecular investigation to molecular network research might result in dis-covering clinical implications faster and more efficiently .Molecular characterization of tumour cells enables refinement of classifications for many cancers and can sometimes guide treatment. Malignant diseases are no longer classified only by tumour site and histology but are separated into various homogenous molecular subtypes, distinguished by a presumed key molecular alteration. Therapies for patients with cancer have changed gradually over the past decade, moving away from the administration of broadly acting cytotoxic drugs towards the use of more-specific therapies that are targeted to each tumour. To facilitate this shift, tests need to be developed to identify those individuals who require therapy and those who are most likely to benefit from certain therapies. In particular, tests that predict the clinical outcome for patients on the basis of the genes expressed by their tumours are likely to increasingly affect patient management, heralding a new era of personalized medicine. In this review a brief discussion on definition and molecular aspects of personalized medicine and its practical application for the management of common solid cancers are highlighted.J Bangladesh Coll Phys Surg 2014; 32: 153-163

This article explores the classical terms and concepts of cultural anthropology, which have found practical application in the performances, paratheatrical experiments and actions of the Polish experimental stage director Jerzy Grotowski (1933–1999) and collectives of the modern anthropological theater that continue the pursuits of Grotowski of the late XX century. The methods and terms of cultural (social) anthropology by A. van Gennep, V. Turner, M. Eliade, B. Malinowski and structural anthropology by C. Levi-Strauss give a better perspective on the specific terminological apparatus of Grotowski, unique practical discoveries of his works, and conceptual basis of theatrical anthropology as one of the paramount phenomena in the development of modern art. This article is first to discuss the problems of the emergence and formation of anthropological methodology as the framework for creating a scientific apparatus for understanding ritual-theatrical forms, as well as practical tool for artistic expression in the theatrical and paratheatrical experiments. Based on the fundamental works of the school of cultural anthropology, the author reveals the key terms of modern anthropological theater. As a result of studying the methods and approaches of cultural anthropology, the author determines the new unique technique of the modern Polish theater ensembles based not on the reconstruction of theatrical forms of the past, but rather reactualization of the mythological structures in the process of creating ritual-theatrical action.

Health and safety regulations have always been concerned with risk, though not always overtly. The quantitative expression of risk does not appear in regulations and rarely in guidance materials but is inherent in the policy underlying the development of regulations and in their practical application. The ways in which actual and perceived expressions of risk are used in regulatory actions differ widely. Some dangers are treated as unaccept­able and the regulatory policy is to exclude them totally. In the real world, such policies are never completely successful. The head-on collision of trains in main-line working is one example. The deliberate use of known carcinogens as pesticides is another. Other dangers are recognized as inevitable but as being reducible in degree. The regulatory activity is then aimed at limiting the extent to which a citizen can expose other citizens to this danger and, more recently, the extent to which he is permitted to put himself at risk. The balance of risks and benefits and of one risk with another underlie decisions in these cases. Not only consequences but probabilities become relevant. In the past, all, and even now most, of the regulation of risk has been on a non-quantitative basis. Increasingly, there is a desire to make the process more quantitative and to introduce the idea of acceptability. This change is provided for by many of the features of the Health and Safety at Work Act of 1974. Within the framework of that Act, the Health and Safety Commission and its operating arm, the Health and Safety Executive, are developing the more systematic use of quantitative methods of controlling hazards from work activities. The regulation of risk is a growth industry and it behoves us all to clarify our objectives. An aim of zero risk would not be to the benefit of society, but its replacement by more suitable aims is a long and com­plicated process.

Artificial intelligence (AI)-enabled digital marketing is revolutionizing the way organizations create content for campaigns, generate leads, reduce customer acquisition costs, manage customer experiences, market themselves to prospective employees, and convert their reachable consumer base via social media. Real-world examples of organizations who are using AI in digital marketing abound. For example, Red Balloon and Harley Davidson used AI to automate their digital advertising campaigns. However, we are early in the process of both the practical application of AI by firms broadly and by their marketing functions in particular. One could argue that we are even earlier in the research process of conceptualizing, theorizing, and researching the use and impact of AI. Importantly, as with most technologies of significant potential, the application of AI in marketing engenders not just practical considerations but ethical questions as well. The ability of AI to automate activities, that in the past people did, also raises the issue of whether marketing professionals will embrace AI as a means to free them from more mundane tasks to spend time on higher value activities, or will they view AI as a threat to their employment? Given the nascent nature of research on AI at this point, the full capabilities and limitations of AI in marketing are unknown. This special edition takes an important step in illuminating both what we know and what we yet need to research.

Rehabilitation Robotic

The pneumatic muscle actuator (PMA) has been widely applied in the researches of rehabilitation robotic devices for its high power to weight ratio and intrinsic compliance in the past decade. However, the high nonlinearity and hysteresis behavior of PMA limit its practical application. Hence, the control strategy plays an important role in improving the performance of PMA for the effectiveness of rehabilitation devices. In this paper, a PMA-based knee exoskeleton based on ergonomics is proposed. Based on the designed knee exoskeleton, a novel proxy-based sliding mode control (PSMC) is introduced to obtain the accurate trajectory tracking. Compared with conventional control approaches, this new PSMC can obtain better performance for the designed PMA-based exoskeleton. Experimental results indicate good tracking performance of this controller, which provides a good foundation for the further development of assist-as-needed training strategies in gait rehabilitation.
