An overview of the transport key and the coinage system

Bibliography Introduction This article presents a summary, overview, and quantification of a large sample of numismatic material from Roman Africa — modern day Morocco, Algeria, Tunisia, and Libya — during the high imperial period.

Food processing supplies also move globally and include processing equipment, packaging, and chemicals such as disinfectants and preservatives. Agricultural inputs move too, from feed to fertilizer, to vaccines and pharmaceuticals, to planting and harvesting equipment.

As agricultural commodities are combined with other food ingredients to create processed foods, individual food items commonly include ingredients from multiple countries. Government regulatory systems and private-sector initiatives are part of food systems, as are educational efforts and consumer actions.

Food systems are integrally related to food safety. Contamination can occur at any point in the food system, and prevention and control strategies can be implemented at any point.

The scale and complexities of today's food systems contribute to the likelihood and magnitude of food-borne illness Ercsey-Ravasz et al. The more complex, the more opportunities for things to go wrong; the larger the scale, the more people are potentially affected.

Complex food systems each involve interconnected subsystems that, taken together, exhibit properties that are not predictable by the properties of the individual subsystems or their parts.

Food systems can be called complex adaptive systems. These have no boundaries; individual actions affect the food systems by what individuals produce and what they purchase. Complex adaptive systems have a memory. While food systems change over time, present behavior is affected by prior behavior.

Food systems are nonlinear. A small perturbation in some part of the system may have a large effect, a proportional effect, or no effect.

And the relationships of this system of systems have feedback loops.

The adaptiveness and nonlinearity of food systems mean that food safety problems are also nonlinear; they can be anticipated but are hard to predict with accuracy or precision.

Feeding the world requires a multitude of systems. Each system is dynamic and the food systems are interdependent; there is no one best system that meets all needs. However, every success in improving the food system perturbs the whole system of systems and changes the nature of the food safety problems.

Lessons for the Future Looking at existing global food systems and predicated demands for food, we can reasonably speculate the following over the next 10 to 20 years: Food systems will continue to change, although with additional drivers.

The drivers of urbanization, production and processing technology, transport technology, and political forces that have played a large part in shaping current food systems will continue to be relevant.

Newer drivers playing an increasingly important part are a real prospect of a global population of 10 billion, aging populations changing the production and consumption base, climate change leading to constraints on water supplies, severe constraints on nonrenewable energy, and communication technology.

Food systems will continue to shift from being supply driven to being demand driven. The global quick service restaurant chains like McDonalds and big-box retailers like Walmart have had an enormous impact on food systems.

The large processors are putting pressure on the primary producers of plants and animals for assurances on source, on identity preservation, on means of production, and on characteristics like animal welfare and labor standards. Increasing prominence of private standards.

The SPS established a framework for international standards for trade in animals, plants, and the products derived from them including food. Food safety standards used by the large companies who target premium market niches are often above and ahead of the minimum demanded by legislation.

The increased growth in connectedness and efficiency results in a lack of redundancy and at the same time makes individual food systems less resilient, more sensitive to stress, and therefore more susceptible to collapse.

If subsystems within complex food systems collapse, the result is systems with greater resiliency that have fewer connections and less efficiency.

And the cycle starts again. Food systems have demonstrated adaptive cycles as they have evolved. Many current food systems have evolved to a point where they are both complex and sensitive to stress, and the results of a collapse in a subsystem can be wide-reaching.

Improving Food Safety Through a One Health Approach: Workshop Summary.

For example, the concentration of production of an ingredient like a vitamin in a single company or country may be the most efficient approach, but if a production problem ensues or a disaster disrupts this supply chain, then all food processors using this vitamin as a food ingredient are affected.

They must either remove the vitamin from their recipes or stop production because of lack of supply. Instead of stockpiling food supplies in warehouses, many large food retailers and food services have worked with food manufacturers to establish these supply chains.Coarsening (i.e., ripening) of single-atom-high, metal homoepitaxial islands provides a useful window on the mechanism and kinetics of mass transport at metal surfaces.

Cash-in-transit (CIT) or cash/valuables-in-transit (CVIT) is the physical transfer of banknotes, coins, credit cards and items of value from one location to another. The locations include cash centers and bank branches, ATM points, large retailers and other premises holding large amounts of cash such as ticket vending machines and parking meters.
