“What’s in a name?” asks Shakespeare’s Juliet of her beloved Romeo when sworn family enemies, the Montagues and the Capulets, forbid their affair. But, while a rose by any other name may indeed smell as sweet, there are certain areas of human endeavour that pick their names very carefully. I’m thinking of the likes of the world of genetic science wherein exist the likes of Sonic Hedgehog genes and in magnetic resonance spectroscopy with its bizarrely named COSY, NOESY and SLITDRESS techniques…then there is the world of algorithms where the behaviour or social, swarming and foraging animals are used to add a clue as to the nature of the process in question, Forget “Blum Blum Shub” and the lagged Lagged Fibonacci generator, forget the Travelling salesman problem and Lexicographic breadth-first search, here we have:

“Shuffled Frog Leaping” is one technique that features in a forthcoming paper in the International Journal of Bio-inspired Computation from Farzan Rashidi, Ebrahim Abiri, Taher Niknam, Mohammad Reza Salehi on optimising power plants.

The pros and cons of “Bat Foraging” and “Cuckoo Search” in spam filtering are compared in a paper from Arulanand Natarajan, S. Subramanian, and K. Premalatha in the International Journal of Bio-Inspired Computation

Mohammad Reza Jabbarpour, Hossein Malakooti, Rafidah Md Noor, Nor Badrul Anuar, Norazlina Khamis discussed “Ant Colony Optimization” in the context of road traffic also in the International Journal of Bio-Inspired Computation.

One usually thinks of shoals of fish and schools of whales, but “Artificial Fish Swarm” optimisation is the order of the day on this paper on natural language processing published in the International Journal of Artificial Intelligence and Soft Computing.

The “Artificial Bee Colony Algorithm” is widely used and comes into its own in a paper on profitable undirected routing published in the International Journal of Operational Research

In 2009, “Glow-worms Swarm Optimization” was a new method for optimising multi-modal functions according to work published in the International Journal of Computational Intelligence Studies by K.N. Krishnanand and D. Ghose. Xiangqin Xiang reports on an improvement to the related “Firefly Algorithm” for numerical optimization in the International Journal of Computing Science and Mathematics

And, the “Eagle Strategy” soars in a paper from Xin-She Yang and Suash Deb published in the International Journal of Bio-Inspired Computation.

Then there is “Bacterial Colony Foraging” “Bug Triaging Based on Ant Systems”, the “Krill Herd Algorithm”, “Bee-inspired Metaheuristics”, “Bee Royalty Offspring Algorithm”, “Slime Mould Computers”. The list goes on and they’re all bio-inspirational…

Call for papers: "Service-oriented Software Architecture and Assessment in the Future IOT Environment"

For a special issue of the International Journal of Services Technology and Management.

SOA (Service-oriented architecture) is a flexible set of design principles used during the phases of systems development and integration in computing, and a system based on SOA architecture will provide a loosely integrated suite of services that can be used within multiple separate systems from several business domains. Recently, as SOA is having a substantial impact on the development of software architecture, many architectures/systems are being developed and designed by utilizing the SOA-based style.
Although some progress has been made in several aspects regarding various issues including assessment concerns, there still exists the need for much research addressing SOA-based software architecture in terms of design, development and operation.
This special issue aims at bringing together researchers and practitioners with the common objective of developing SOA-based software architecture and methods into a mature discipline with both solid scientific foundations and mature software engineering development methodologies. In particular, we encourage work and discussions addressing what SOA-based software architecture still needs in order to achieve its original goal. Papers on practical as well as theoretical topics and problems are welcome.
Suitable topics include, but are not limited to, the following:
  • Software architecture for legacy systems and systems integration
  • Software architecture from ultra-large to very small systems
  • Service-oriented architecture, SOA migration and governance
  • Software testing models and approaches
  • SOA-based software testing and maintenance
  • SOA-based software quality assurance
  • Software security on the Internet of Things
  • Software education and its applications

Call for papers: "Entrepreneurship: Made in German (Language)"

For a special issue of the International Journal of Entrepreneurship and Small Business.

German is hip again. German is not only the most widely spoken native language in the European Union, but there is also a global increase in persons interested in learning German as a foreign language. Moreover, the German language area has for decades now been a major growth engine of the global economy.
Against this backdrop, the aim of this special issue is to explore entrepreneurship in the German-speaking countries Germany, Switzerland, Austria and Liechtenstein to get a better understanding of the stories, reasons and antecedents behind this successful development. Furthermore, we are no less interested in contributions on entrepreneurship in Germanophone (border) regions such as in Denmark, Belgium, Luxemburg, France, Italy, Poland, Slovakia, Russia, Kazakhstan, Namibia, Brazil, Chile and further countries where German is a national minority language.
In this broadest sense of German, submissions could also focus on the export of German expatriate entrepreneurs and business models, capture perceptions of German entrepreneurship abroad (e.g. in China), or revisit particularities of German entrepreneurship research (Schmude et al., 2008).
We invite theoretical, conceptual and empirical submissions, and are particularly keen to read daring, ironic or surprising perspectives on German entrepreneurship.

Social sharing and popular posts

Sharing to be sociable or posting to be popular? Whatever your stance on social media it seems from recent research in the Netherlands that a student’s decision to share information on Facebook is predicated primarily on their perception of the benefits of sharing and not on their privacy concerns.

Writing in the International Journal of Web Based Communities, Ardion Beldad of the Department of Corporate and Marketing Communication, at the University of Twente, explains how Facebook use is closely tied to the need to disclose various types of personal information for users to experience the full benefits of using the platform. He wanted to know whether Dutch vocational students are actually deterred from sharing potentially sensitive personal and private information given awareness of risks and privacy valuation of the site.

His survey of almost 300 students revealed that the majority are quite happy to share photos, statements of their current activities, thoughts on issues or products regardless. The benefits derived from ease of communication and connectivity between friends and members of an online social network, and Facebook, in particular, seem to be perceived as far outweighing any problems that might arise from users sharing such vast amounts of information about themselves.

Aside from the issue of advertisement targeting that becomes easier for the provider of a social network given this plethora of personal information, there are also the risks of exposure to a wider and potentially malicious “audience”, either inadvertently through inappropriate privacy settings or should an online social network be hacked. “Users seem unperturbed by the negative repercussions of disclosure, as information sharing proceeds unabated,” Beldad reports.

He adds that, “Analysis reveals that people with more Facebook contacts are more inclined to share personal information on their Facebook walls than those with fewer contacts.” Moreover, “Those who have been members of the platform for a relatively long period tend to share personal information more frequently than those who are new to the site.”

Call for papers: "Vehicle Routing Problems: Formulations and Solution Algorithms"

For a special issue of the International Journal of Decision Support Systems.

The vehicle routing problem is one of the most important problems in the field of supply chain management of logistics, of combinatorial optimisation and, in general, of operational research.
Interest in this problem has recently increased from both the theoretical and practical perspectives. From the practical point of view, the problem is one of the most crucial ones in supply chain management and, thus, the finding of the optimal set of routes will help decision makers to reduce the cost of the supply chain and increase profit. In the formulation of the problem, managers can simulate the complete network and add any constraints concerning customers, vehicles, routes and, additionally, the traffic conditions of the network and the energy consumption of the vehicles.
From the theoretical point of view, there are a number of researchers that deal with the solution of a variant (or more variants) of the problem. These variants of the problem focus on specific constraints and the researchers are trying to find an algorithm that gives the best new solutions in a specific set of benchmark instances or in problems from real life.
For this special issue, we invite contributions in both theoretical and practical aspects of the vehicle routing problem.
Suitable topics include, but are not limited to, the following:
  • Variants of the vehicle routing problem
    • Capacitated vehicle routing problem

Chewing over the aging process

Could scientists use the Second Law of Thermodynamics on your chewing muscles to work out when you are going to die? According to research published in the International Journal of Exergy, the level of entropy, or thermodynamic disorder, in the chewing muscles in your jaw increases with each mouthful. This entropy begins to accumulate from the moment you’re “on solids” until your last meal, but measuring it at any given point in your life could be used to estimate life expectancy.

The Second Law of Thermodynamics states the precise opposite of the optimistic phrase “things can only get better”. In fact, the disorder in a closed system, its entropy, always increases…eventually. In other words, things can only get worse. Castles of stone or sand eventually collapse, the bodies of those who build such castles ultimately decay, in the meantime the food they eat is broken and only temporarily rebuilt into muscles. The masseter muscles, for instance, strong and the most prominent chewing muscles in the jaw that are particularly powerful in herbivores, but all mammals use these muscles to chew.

While we live and breathe our bodies have repair systems for mending damaged tissues, but they do suffer wear and tear, mainly through friction. Nevertheless, Mustafa Özilgen of the Department of Food Engineering, at Yeditepe University, in Istanbul, and colleagues, point out that the lifespan entropy concept suggests that organisms have a limited capacity for generating disorder, entropy, during their lifetime. When that limit is reached, the organism dies, essentially “of natural causes”.

A person living out their three score years and ten, or perhaps more realistically in the modern era, 76 years on average will generate 10 kilojoules per degree Kelvin of entropy in their masseter muscles as they chew from out of the cradle and into the grave. An obese person, who may be taking up 10 percent more nutrients than their slim friend, may generate that same amount of entropy five years earlier. A more efficient body, and specifically more efficient muscles will take longer to generate entropy. As such, the team says, it should be possible to determine entropy of the masseter muscles under laboratory conditions by recording precise energy measurements of the tissue while a person chews and so provide an estimate of lifespan based on likely quantities of food they eat each day through their lives.
