As collections become larger in size, more complex in structure and increasingly diverse in composition, new approaches are needed to help curators assess digital files and make decisions about their long-term preservation. We present research on the use of interactive visualization to analyze file characterization information for the purpose of assessing the preservation condition of a vast collection of complex electronic records. The case study collection contains over 1,000,000 files of diverse formats arranged in varied record structures and record groups. The visualization application uses tree maps and a relational database management system (RDBMS) to represent the collection's arrangement and to show available characterization information at different levels of aggregation, classification and abstraction. Through this visualization interface curators can interact dynamically with the collections' characterization information to discover trends, as well as compare and contrast various file characteristics across the collection. Curators may select and weight the variables that they want to analyze. They can pursue analysis workflows that go from a high-level overview of the collection's preservation condition based on file format risks, to obtaining more detailed results about the condition of record groups and individual records. While there are various digital preservation planning tools available, to our knowledge none have been designed specifically to visually present assessment information across vast and complex collections. We present research to address the need for such a tool.

Key concepts: We review interdependence theory measured by entropic forces, findings in support, and several examples from the field to advance a science of autonomous human-machine teams (A-HMTs) with artificial intelligence (AI). While theory is needed for the advent of autonomous HMTs, social theory is predicated on methodological individualism, a statistical and qualitative science that neither generalizes to human teams nor HMTs. Maximum interdependence in human teams is associated with the performance of the best teams when compared to independent individuals; our research confirmed that the top global oil firms maximize interdependence by minimizing redundant workers, replicated for the top militaries in the world, adding that impaired interdependence is associated with proportionately less freedom, increased corruption, and poorer team performance. We advanced theory by confirming that the maximum interdependence in teams requires intelligence to overcome obstacles to maximum entropy production (MEP; e.g., navigating obstacles while abiding by military rules of engagement requires intelligence). Approach: With a case study, we model as harmonic the long-term oscillations driven by two federal agencies in conflict over closing two high-level radioactive waste tanks, ending when citizens recommended closing the tanks. Results: While contradicting rational consensus theory, our quasi-Nash equilibrium model generates the information for neutrals to decide; it suggests that HMTs should adopt how harmonic oscillations in free societies regulate human autonomy to improve decisions and social welfare.

Subject area Diplomatic and consular policies; legal aspects of international relations and Asia regional scenario. Study level/applicability Undergraduate. Case overview In April 2012, high-level officials from China and the USA were about to meet in Beijing in the framework of the bilateral Strategic and Economic Dialogue, organized on a yearly basis. The event was always delicate, due to the ambiguous relationship existing between the two countries, which were at the same time rivals and dependent on one another. That time, the tension previous to the meeting increased significantly: a Chinese human rights activist had just sought and obtained diplomatic protection in the US Embassy in Beijing, thus creating an embarrassing situation for both States' foreign departments […] How could they possibly solve this contentious issue without affecting their already sensitive relationship? Expected learning outcomes Analytical: to be aware of the political nature of the current Chinese Government; to realize the concrete and practical implications of an Embassy's special status; to balance two contradictory objectives, in a specific situation where none of them can be fully discarded; to contrast and try to combine long-term goals (in this case, to maintain a functioning relationship between two main world powers) with short-term objectives (in this case, how to deal with a Chinese activist that required protection against his own country's security forces); to find a modus vivendi (conciliation) between values and interests; to get convinced that certain kinds of negotiations cannot be conceived through a “win or lose” approach: in this case, the only way out must be respectful of the two parties' core interests; and to take into account that image preservation (“face-saving”) must be included within any country's objectives in any situation involving diplomatic means. Conceptual: the purpose is to familiarize the students with specific concepts, such as: best alternative to a negotiated agreement (BATNA), which is to be mentioned as part of the discussion (it is not included in the case study itself); interdependence; (purported) Group of Two; asylum and refuge; Immunity; and sending state/receiving state.

Munna Point is a premiere recreational beach in the Noosa River which has been maintained by regular nourishment for over 20 years. As longevity of each nourishment was less than 6 months, the long-term costs were high and efforts were eventually suspended resulting in loss of the beach. In an effort to reinstate the amenity and provide a more stable beach, a groyne field accompanied by nourishment was proposed. To provide a low-impact, low-risk and low-cost solution, the groynes were designed with a low crest using sand-filled geotextile containers. To achieve the design, containers and scour mattresses were filled in-situ using a dredge, which was an innovative application of a methodology typically adopted for much larger containers. The first 3 groynes have successfully been installed as part of the first stage and 12 months of monitoring subsequently undertaken. The groynes have clearly been effective at extending the longevity of the nourishment and the wider intertidal profile has remained very stable. The beach is now successfully enhancing the amenity of the community and experiencing a high level of usage.

Due to the natural limitations faced by the old system of keeping, planning and managing the distribution of electricity, a computerized system is developed for Power Holding Company of Nigeria (PHCN), on Ashamu Layout of Kosobo Area, Oyo State, Nigeria. Data was acquired using south total station (NTS) and the data was downloaded using NTS.comp and project boundary was plotted with AutoCAD civil 3D, 1m Ikonos resolution satellite imagery was downloaded and geo-referenced with Arcgis10.1. Spatial features such as roads and buildings were vectorized. Electricity distribution and management was designed and created using relational database management system (rdbms) approach. The raster image was added as layer to ArcGIS 10.1 environments for geo-referencing and vectorization. The roads, buildings, electric poles were vectorized and a south total station was used to acquire co-ordinates of the electric poles and transformers to their position on the imagery, creating spatial database for the study area. The developed system was tested by carrying out spatial analysis and spatial search using ArcGIS 10.1. The results obtained were displayed in graphics and tables. It was established from the result that Geographic Information System (GIS) has the capacity as an effective tool for management of electricity distribution system.

Background: The current research brings up the perspective of security-critical information systems in shared parameter databases in the context of processing sensitive data at Finnish Naval Warfare Centre. It refers to the environment of isolated military war gaming simulation and modeling systems. The research problem is: How to make an optimal solution for data distribution in different military war gaming simulation and modeling software? Objectives: The objective is to create a single shared database usable with different detail level software, e.g. high-level scenario simulation, technical system-of-system simulations, and system-level physical simulations. Methods: The methods are modeling, simulation and operation analysis. The approach is inductive, the strategy is a qualitative case study and the data collection was implemented by exploring database models and their combinations. The integration was implemented in an object-relational database management system (ORDBMS), PostgreSQL. Results: The shared database led to efficient access to simulation parameters, more straightforward system integration and improved scalability. Conclusions: The results of modeling and simulation indicated that the integration is possible to implement.


In the decades since Singapore’s independence in 1965, the nation has transformed from one facing basic challenges related to sanitation and disease prevention, to a world-class economy and a gold standard for health care. Factors that contribute to this trajectory include a stable government with a long-term vision of how Singapore should grow economically, guided by a high-level Economic Review Panel of global and local business leaders, international and local academics, and political officeholders. This group meets periodically ...

DACUM (develop a curriculum) was implemented at Kent State University (KSU) to develop and revise curricular content of an associate degree program in horticulture technology. Initially, at KSU-Salem in 1990, a committee followed a typical DACUM process to develop a skills profile for the horticulture technology worker. The skills profile consisted of terminal and intermediate learning objectives that served as the content of basic data sheets for thirteen new courses in horticulture technology. This associate degree program was initiated at Salem in 1991 and offers three concentration areas: landscape management, turfgrass management, and arboriculture. Later, when a proposed new program offering was considered at KSU-Geauga, a modified DACUM process was implemented to develop a new skills profile that refl ected both general knowledge areas of horticultural and business practices and industry-spe- cific competency areas. Comparison of the two curricula revealed similarities between the two skills profiles. This led to the recommendation that the original curriculum also be offered at KSU-Geauga campus with two differences: 1) omit the arboricul- ture concentration, and 2) consider a new concentration in greenhouse and nursery operations in the future. The associate degree program in horticulture technology at the KSU-Geauga campus began in 1999. The DACUM process, by involving members of the horticultural industry in the curricular development process, provided several long-term benefits and a high level of cooperation between industry leaders and KSU-Geauga.

Owing to the increasing population in Kirkuk, Iraq and the consequent rise in the production of waste, alongside with global warming caused by an increase in the greenhouse gases concentrations, a high level of emissions was observed at the landfill site near Kirkuk. These emissions can be transmitted by the wind over considerable distances and adversely affect the environment and individual health. In this study, two pilot scale columns were built to investigate different options for achieving sustainability by reducing long-term landfill emissions. Each reactor was packed with (8.5) kg of shredded synthetic solid waste (less than 5 cm) that was prepared according to an average composition of domestic solid waste in the city of Kirkuk. The main result of this study was that the pretreatment of the waste may shorten the transition time for active methane development and increase the methanogenesis of the landfill site and also affects COD removals efficiencies which were 19.11% and 66.53% for columns A and B respectively.

During the COVID-19 pandemic, China has achieved high recovery efficiency. One of the most important reasons behind this is the effective poli­cies of promoting work resumption. Why can such policies maintain steady performance despite the high level of environmental uncertainties? This ques­tion can be answered from the perspective of policy resilience. This study employed a policy evaluation model for analyzing quantitative data of 342 poli­cies of promoting work resumption. We evaluate the policies through the Policy Modeling Consistency (PMC-index) model and text mining methods. The results show that: first, the contents and elements of all policies have consistent characteristics, including the combination of multiple policy tools, the combi­nation of support for work resumption and pandem­ic control, the incentives to support effective policy implementation, and the reasonable match between macro and micro policies as well as short-term and long-term policies. Second, among the nine policies that are randomly selected from the sample, one is rated excellent and the other eight are good, indicat­ing that China’s policies of promoting work resump­tion have good resilience.
