Traditional arable management practice has tended to manage fields uniformly and has tended to ignore the inherent spatial variability found on most farms. This has been exacerbated by the increase of field size due to pressures from mechanization. Precision farming is a management practice that has been made possible by the advent of suitable information technologies, and it provides a framework within which arable managers can more accurately understand and control what happens on their farms.

Abstract With the rapid development of the Internet of Things and information technologies, more and more manufacturing systems become cyber-enabled, which significantly improves the flexibility and productivity of manufacturing. Furthermore, a large variety of online sensors are also commonly incorporated in the manufacturing systems for online quality monitoring and control. However, the cyber-enabled environment may pose the collected online stream sensor data under high risks of cyber-physical attacks as well. Specifically, cyber-physical attacks could occur during the manufacturing process to maliciously tamper the sensor data, which could result in false alarms or failures of anomaly detection. In addition, the cyber-physical attacks may also illegally access the collected data without authorization and cause leakage of key information. Therefore, it becomes critical to develop an effective approach to protect online stream data from these attacks so that the cyber-physical security of the manufacturing systems could be assured. To achieve this goal, an integrative blockchain-enabled method, is proposed by leveraging both asymmetry encryption and camouflage techniques. A real-world case study that protects cyber-physical security of collected stream data in additive manufacturing is provided to demonstrate the effectiveness of the proposed method. The results demonstrate that malicious tampering could be detected in a relatively short time and the risk of unauthorized data access is significantly reduced as well.

With the German jurist-philosopher-author Juli Zeh chapter 13 asks the jurist to consider the effects of contemporary information technologies on the human. It discusses topics such as privacy, surveillance and control societies in relation to individual autonomy and free will. With Zeh’s novel The Method it shows the consequences of state ideology writ large and it asks the reader to consider in which ways humans are being nudged into complacency by modern technologies that provide all our modern conveniences. It shows that as a result of modern technologies human beings run the risk of being reduced to objects ready to be used for further ordering by others.

With growing maturity of social media over the last few years, many companies started using these tools to interact with customers and employees. Business functions such as Sales, Marketing and Human Resources have innovatively embedded these technologies to support their processes and became, as such, an instrument for renewal. The use of social media in Project Management, however, seems to be very limited. The profession lags behind having difficulty keeping pace with the rapidly evolving web 2.0 driven technological innovations which are delivering on their promise to foster collaboration. The paper discusses the potential of social media in the project management practice. As the move towards harnessing the power of social media within the Project Management framework requires adequate organizational change, the study also addresses the implications of such an initiative on structure, culture, and control.

The need of eco-friendly pest management practice is important to maintain soil biodiversity and sustainable agriculture. Therefore rigorous investigation is needed for the environmentally friendly pest management techniques worldwide including Nepalese Tomato growing farms. We conducted field experiment to monitor the diversity and community structure of soil nematodes under different pest management practices in Tomato (Lycopersicon esculentum) growing farm. The study was conducted during summer and winter season in 2015 in Tokha area of Northern part of Kathmandu valley. The field was designed as Urine mixture plot (MP), Pesticides plot (PP), Botanicals plots (BP) and Control plot (CP). Our result indicated the variation of abundance and diversity of nemato-fauna with treatment plots and seasons. The generic diversity and community composition of nematodes in Urine mixture treating plots (MP) was increased significantly whereas decreased in pesticide applying plot (PP). The F/B ratio was significantly affected with treatment system rather than seasonality and found to be increased in pesticides applying plots. The abundance samples of nematodes genera were well separated in our discriminate ordination. We highlight the need of further exploration on the diversity and community dynamics of soil nematodes under different pest management practices in Tomato growing Nepalese agro-farms for sustainable soil ecosystem service. Journal of Institute of Science and Technology Volume 22, Issue 2, January 2018, Page: 45-55

Marketing Messages

Traditional companies used to design products, evaluate marketing messages, and control product distribution channels with a low level of customer contribution. Nonetheless, with the advancements in communication and information technologies, the interaction between customers and company is much higher compared to the past, and it is no longer solely controlled by the companies; thus, users can now impact companies by simultaneously playing two roles as value creators and as consumers. The present study develops a conceptual framework for value co-creation in small- and medium-sized tourism agencies. The sample consisted of 23 purposefully selected employees and managers of small- and medium-sized tourism agencies. Data were extracted from semi-structured interviews and analyzed with open and axial coding. For validity, an eight-person panel of experts was asked to review the framework and to apply corrective comments. The reliability was tested using a re-test method, which confirmed the reliability of the coding with a re-test reliability of 79%. Based on the findings, the proposed framework contains eight components including value inception, value conception, value risk, resource planning, platform, actors, co-creation process, co-created value, and learning process, whose components were identified and encoded.

Combine Load

We use parametric and nonparametric methods to estimate correlations between average control cost and three field-level characteristics—field size and delivered phosphorous per field and per acre—as proxies for economies of scale in controlling nonpoint pollution. We combine load and delivery-ratio estimates for more than 12,000 fields in the Bear River Basin, Utah, with estimates of control costs and effectiveness of management practices from the literature. Results suggest a negative relationship between control cost and delivered phosphorous per field and per acre. Ranking fields by phosphorous load therefore prioritizes management-practice subsidies by economies of scale.
