A Novel Hybrid Approach to Estimate Customer Interruption Costs for Industry Sectors  [PDF]
Sinan Kufeoglu, Matti Lehtonen
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510A006
Abstract:

The power system infrastructure, operations and market have gone through radical changes for the last couple of decades. The society has become more dependent to the continuous electric power supply and hence the concept of electric power reliability has become more significant. At this point, understanding the economic outcomes of power outages is vital and imperative for both utilities and the customers. There are certain methodologies to understand the costs of power interruptions. This paper suggests a novel hybrid method that comprises of customer surveys and direct analytical methods to reach customer specific, objective and reliable results for the industry sector customers. The paper also brings a statistical approach to censor the zero and extreme responses given via the surveys.

Vehicles, Replicators, and Intercellular Movement of Genetic Information: Evolutionary Dissection of a Bacterial Cell
Matti Jalasvuori
International Journal of Evolutionary Biology , 2012, DOI: 10.1155/2012/874153
Abstract: Prokaryotic biosphere is vastly diverse in many respects. Any given bacterial cell may harbor in different combinations viruses, plasmids, transposons, and other genetic elements along with their chromosome(s). These agents interact in complex environments in various ways causing multitude of phenotypic effects on their hosting cells. In this discussion I perform a dissection for a bacterial cell in order to simplify the diversity into components that may help approach the ocean of details in evolving microbial worlds. The cell itself is separated from all the genetic replicators that use the cell vehicle for preservation and propagation. I introduce a classification that groups different replicators according to their horizontal movement potential between cells and according to their effects on the fitness of their present host cells. The classification is used to discuss and improve the means by which we approach general evolutionary tendencies in microbial communities. Moreover, the classification is utilized as a tool to help formulating evolutionary hypotheses and to discuss emerging bacterial pathogens as well as to promote understanding on the average phenotypes of different replicators in general. It is also discussed that any given biosphere comprising prokaryotic cell vehicles and genetic replicators may naturally evolve to have horizontally moving replicators of various types. 1. Introduction Viruses that infect prokaryotic cells are known to be enormously diverse in terms of genetic information [1, 2]. Most novel viral isolates are likely to have at least some genes that have no homologues among any of the previously known genes, including those in the genomes of related viruses [3]. Yet, there has been a dispute whether or not new genes may actually emerge in viruses [3]. Viruses are dependent on cellular resources such as nucleotides, amino acids, and lipids for producing more viruses; therefore it seems justified to ask whether they also use cellular genes for their genetic information. Yet, when viral genes are compared to other genes in databases, it often appears that they have no cellular counterparts [2]. Where then do these viral genes come from? Have they been acquired from a cellular host that we simply have not sequenced before? Or alternatively, are the cellular genes perhaps just evolving rapidly in viral genomes so that their common ancestry with the host genes can no longer be derived? Or perhaps, is it indeed possible that new genes actually emerge in viruses themselves? Forterre and Prangishvili from Pasteur Institute
The Marketplace Variables in Successful and Unsuccessful NPD Projects in Technology Intensive Companies
Haverila,Matti;
Journal of technology management & innovation , 2010, DOI: 10.4067/S0718-27242010000400010
Abstract: we present an exploratory investigation of how managers conceptualize and perceive 'marketplace' variables in successful and unsuccessful new product development (npd) projects, and explore the role that marketplace variables play in differentiating between successful and unsuccessful npd outcomes. limitations and future research directions are also discussed. our findings indicate that managers perceive the marketplace in multiple ways during the npd process and also that differences exist in metric equivalence across successful and unsuccessful npd projects. also, although half of the marketplace variables are positively related to npd success, managers in finnish technology companies appear to attach higher relative importance to market attractiveness rather than market competitiveness variables. marketplace variables appear to be less important than in the korean and chinese samples, and much more important than in the canadian sample in the mishra et al. study (1996), and similarly much more important than in the cooper study (1979b).

SIOG (International Society of Geriatric Oncology) recommendations for anthracycline use in the elderly
Matti Aapro
Hematology Reports , 2011, DOI: 10.4081/hr.2011.s3.e6
Abstract: A taskforce of the International Society of Geriatric Oncology (SIOG) has recently submitted recommendations on the use of anthracyclines in elderly patients. Despite the aging of the population and the high proportion of elderly individuals in the population of patients with non-Hodgkin’s lymphoma, the development of specialist expertise in the treatment of elderly patients with cancer is relatively recent. Treatment of the elderly is complex because they are a highly heterogeneous population, with large variations in health status, comorbidities and life expectancy. In addition, these patients are generally more susceptible than young patients to the cardiotoxic effects of anthracyclines. Strategies for assessing elderly patients with cancer, reducing the risk of congestive heart failure, and assessing the cardiotoxic effects of treatments are discussed. In addition, a summary of the SIOG recommendations is presented.
Du an Coti and the European institute: Bridging the gap
Joutsen Matti
Temida , 2012, DOI: 10.2298/tem1202031j
Abstract: The paper describes the context in which the European Institute, on its establishment, identified Professor Du an Coti as the ideal candidate to serve on its Advisory Board and an internationally oriented criminal justice practitioner and criminologist, so that the Board could bridge the gap between East and West, and academia and practice. Professor Du an Coti served on the Board with distinction.

Useful model organisms, indicators, or both? Ground beetles (Coleoptera, Carabidae) reflecting environmental conditions
Matti Koivula
ZooKeys , 2011, DOI: 10.3897/zookeys.100.1533
Abstract: Classic studies have successfully linked single-species abundances, life-history traits, assemblage structures and biomass of carabid beetles to past and present, human-caused environmental impacts and variation in ‘natural’ conditions. This evidence has led many to suggest carabids to function as ‘indicators’ a term that bears multiple meanings. Here, a conservation-oriented definition for an indicator is used, carabid indicator potential from seven views is evaluated, and ways to proceed in indicator research are discussed. (1) Carabid species richness poorly indicates the richness and abundance of other taxa, which underlines the importance of using multiple taxa in environmental assessments. The ability of assemblage indices and specialist or functional-group abundances to reflect rare species and habitats should be examined in detail. (2) Experimental evidence suggests that carabids may potentially serve as keystone indicators. (3) Carabids are sensitive to human-altered abiotic conditions, such as pesticide use in agro-ecosystems and heavy metal contamination of soils. Carabids might thus reflect ecological sustainability and ‘ecosystem health’. (4) Carabid assemblages host abundant species characteristic of particular habitat types or successional stages, which makes them promising dominance indicators. (5) Carabids reflect variation in ‘natural’ conditions, but vegetation and structural features are more commonly adopted as condition indicators. Carabids nevertheless provide yet another, equally accurate, view on the structure of the environment. (6) Carabids may function as early-warning signalers, as suggested by recent studies linking climate and carabid distributions. (7) Carabids reflect natural and human-caused disturbances and management, but the usefulness of these responses for conservation purposes requires further research. In summary, European carabids appear useful model organisms and possibly indicators because they are diverse, taxonomically and ecologically well-known, efficiently reflect biotic and abiotic conditions, are relevant at multiple spatial scales, and are easy to collect in sufficiently large numbers to allow statistical analyses. The assumption that carabid responses would reflect rare environmental conditions or the responses of rare and threatened species crucial information for conservationists and managers has not yet been critically evaluated. Even if it holds, the usefulness will be context dependent: species and their populations vary, conditions vary, questions put forward vary, and assessment goals var
Does the Value-Added Tax Shift to Consumption Prices?
Matti Viren
AUCO Czech Economic Review , 2009,
Abstract: This paper deals with the question of how consumption taxes, especially the value-added tax, affect consumption prices. The analyses are based on data from EU countries for the period 1970–2004. The starting point is a conventional supply-demand analysis of the tax incidence problem. This problem is solved using some simple price mark-up equations, Phillips curves and inflation forecast error equations. All these equations are estimated from panel data from EU countries using different estimators and variable specifications. In addition, an analysis is carried out with Finnish excise taxes using commodity/outlet level micro data for the early 2000s. A general result of all analyses is that more than one half of a tax increase shifts to consumer prices. By contrast, there is less evidence on shifts to producer prices.
Gun Laws and Crime: An Empirical Assessment
Matti Viren
International Journal of Social Science Studies , 2013, DOI: 10.11114/ijsss.v1i1.11
Abstract: This paper deals with the effect of gun laws on crime. Several empirical analyses are carried to investigate the relationship between five different crime rates and alternative law variables. The tests are based on cross-section data from US sates. Three different law variables are used in the analysis together with a set of control variables for income, poverty, unemployment and ethnic background of the population. Empirical analysis does not lend support to the notion that crime laws would affect the crime rates. The results seem to be the same for all five crime categories that are analyzed in the paper.
