In case that both the goals of selection quality and diversity are important, a selection system is Pareto-optimal (PO) when its implementation is expected to result in an optimal balance between the levels achieved with respect to both these goals. The study addresses the critical issue whether PO systems, as computed from calibration conditions, continue to perform well when applied to a large variety of different validation selection situations. To address the key issue, we introduce two new measures for gauging the achievement of these designs and conduct a large simulation study in which we manipulate 10 factors (related to the selection situation, sensitivity/robustness, and the selection system) that cumulate in a design with 3,888 cells and 24 selection systems. Results demonstrate that PO systems are superior to other, non-PO systems (including unit weighed system designs) both in terms of the achievement measures as well as in terms of yielding more often a better quality/diversity trade-off. The study also identifies a number of conditions that favor the achievement of PO systems in realistic selection situations.

It is well known that Frame Selection Systems (FFS) have proved both popular and effective in physician-machine and patient-machine dialogue. A formal algorithm for definition of a Frame Selection System for handling man-machine dialogue is presented here. Besides, it is shown how the natural medical language can be handled using the approach of a tree branching logic. This logic appears to be based upon ordered series of selections which enclose a syntactic structure. The external specifications are discussed with regard to convenience and efficiency. Knowing that all communication between the user and the application programmes is handled only by FSS software, FSS contributes to achieving modularity and, therefore, also maintainability in a transaction-oriented system with a large data base and concurrent accesses.

The phylum Perkinsozoa is an aquatic parasite lineage that has devastating effects on commercial and natural mollusc populations, and also comprises parasites of algae, fish and amphibians. They are related to, and share much of their biology with, dinoflagellates and apicomplexans and thus offer excellent genetic models for both parasitological and evolutionary studies. Genetic transformation has been previously achieved for select Perkinsus spp. but with few tools for transgene expression and only limited selection efficacy. We thus sought to expand the power of experimental genetic tools for Perkinsus marinus — the principal perkinsozoan model to date. We constructed a modular plasmid assembly system that enables expression of multiple genes simultaneously. We developed an efficient selection system for three drugs, puromycin, bleomycin and blasticidin, that achieves transformed cell populations in as little as three weeks. We developed and quantified eleven new promoters of variable expression strength. Furthermore, we identified that genomic integration of transgenes is predominantly via non-homologous recombination and often involves transgene fragmentation including deletion of some introduced elements. To counter these dynamic processes, we show that bi-cistronic transcripts using the viral 2A peptides can couple selection systems to the maintenance of the expression of a transgene of interest. Collectively, these new tools and insights provide new capacity to efficiently genetically modify and study Perkinsus as an aquatic parasite and evolutionary model.

Purpose This paper aims to analyse the valuation of cultural products and explores what this process means for organizations involved in their production and marketing. Design/methodology/approach The authors develop the arguments using a number of mini-cases and industry examples. Findings The main thesis is that the meaningfulness and value ambiguity of cultural products shift the focus of valuation away from the products themselves towards how certain agents in the socio-cultural environment identify and certify these products. This paper discuss how valuation takes place via selection systems and how the nature of cultural products drives the dominance of one selection system over others. Research limitations/implications Theories on value creation needs to take consideration of the critical role played by the selection system instead of just the firms that produce these products. Practical implications Organizations engaged in producing highly symbolic products need to manage selection systems and related industry dynamics to establish an enduring competitive advantage. Social implications Value creation is a collective social efforts. Every member of the society can play a central role in this process. Better engaging various member of the society to enable them actively participate in the value creation process is what organizations today need to consider, instead of just treating individuals in the society as a “customer” who only passively consume. This research calls for the true empowerment of every member of the society to facilitate collective creativity and participation in the value creation endeavour that benefits the entire society as a whole. Originality/value It is the first paper that has created a conceptual link between the type of selection system and product categories. In other words, it takes existing literature on value creation and selection system one step further by creating the alignment or match between types of selection system and types of product categories. Therefore, it offers academics and practitioners a much detailed understanding on how value creation is conducted across different product categories.

Private High School

The success of a school, of course, cannot be separated from the roles of teachers and employees. With the presence of teachers who meet predetermined quality standards, the school's productivity will increase and its quality can be maintained. Therefore, the school is required to be able to select a more objective recruitment of prospective employees. A process that is not objective will lead to inaccuracy in selecting prospective employees. To overcome this problem, a candidate recruitment application system is needed that can select prospective employees as needed. This research took place in private high schools in Jakarta. The system development method used in this research is the waterfall. The application developed in this study consisted of three users, namely the principal, assessors and prospective employees. This study produces an application that can be used by the private high school in selecting prospective employees according to their needs.
