Artificial Chromosomes to Explore and to Exploit Biosynthetic Capabilities of Actinomycetes
2012
Actinomycetes are an important source of biologically active compounds, like antibiotics, antitumor agents, and immunosuppressors. Genome sequencing is revealing that this class of microorganisms has larger genomes relative to other bacteria and uses a considerable fraction of its coding capacity (5–10%) for the production of mostly cryptic secondary metabolites. To access actinomycetes biosynthetic capabilities or to improve the pharmacokinetic properties and production yields of these chemically complex compounds, genetic manipulation of the producer strains can be performed. Heterologous expression in amenable hosts can be useful to exploit and to explore the genetic potential of actinom…
RCS1, a gene involved in controlling cell size inSaccharomyces cerevisiae
1991
Cloning and sequencing of RCS1, Saccharomyces cerevisiae gene whose product seems to be involved in timing the budding event of the cell cycle, is described. A haploid strain in which the 3'-terminal region of the chromosomal copy of the gene has been disrupted produces cells that are, on average, twice the size of cells of the parental strain. The critical size for budding in the mutant is similarly increased, and the disruption mutation is dominant in a diploid heterozygous for the RCS1 gene. Spores from this diploid have a reduced ability to germinate, the effect being more pronounced in the spores carrying the disrupted copy of RCS1. However, disrupted cells recover from alpha-factor tr…
The development of Finnish museums over the last forty years
2018
The focus of this article is the development of Finnish museums since the 1970s, when the Ministry of Education started to understand the social benefits of museums as social memory organizations with activities of research and education. At this point in time the Ministry began actively developing the preconditions for museum work, the main ”tools” being several political museum committees which created a museum hierarchy and network, ensured state subsidy through museum acts, established university studies of museology, and gave support to the Finnish Museums Association.
Measuring dissatisfaction with coauthorship: An empirical approach based on the researchers’ perception
2019
Abstract Increasing levels of collaboration constitute one of the characteristics of science. However, the knowledge production system is based on a fundamental discordance: on the one hand, it is cooperative in nature, with links articulated through coauthorships, and on the other, the systems for assigning merit and distributing rewards function on an individual scale. This contradiction can give rise to dysfunction and inappropriate practices. This study analyses researchers’ perceptions about the problems associated with authorship in scientific publications. We make use of a coauthorship dissatisfaction index that measures the degree of dissatisfaction with the author order on the byli…
Dirac neutrinos from Peccei-Quinn symmetry: a fresh look at the axion
2019
We show that a very simple solution to the strong CP problem naturally leads to Dirac neutrinos. Small effective neutrino masses emerge from a type-I Dirac seesaw mechanism. Neutrino mass limits probe the axion parameters in regions currently inaccessible to conventional searches.
Planck scale physics and topology change through an exactly solvable model
2014
We consider the collapse of a charged radiation fluid in a Planck-suppressed quadratic extension of General Relativity (GR) formulated à la Palatini. We obtain exact analytical solutions that extend the charged Vaidya-type solution of GR, which allows to explore in detail new physics at the Planck scale. Starting from Minkowski space, we find that the collapsing fluid generates wormholes supported by the electric field. We discuss the relevance of our findings in relation to the quantum foam structure of space–time and the meaning of curvature divergences in this theory.
An integrated identity verification system for mobile terminals
2005
PurposeTo report the work on the design of an integrated identity verification system architecture aimed at approaching high verification accuracy, continuous security, and user‐friendliness.Design/methodology/approachThe reported research corresponds to the building process in the design science research paradigm. The requirements to an identity verification system are defined and used in the selection of architecture components. Furthermore, various issues affecting the suitability of component distribution between a terminal and a remote server are considered.FindingsIn order to meet the stated requirements, in the proposed architecture static and dynamic identity verification is combine…
Higher Education in Management: The Case of Spain
2017
The history of the management education system in Spain can be described by breaking it down into four periods: (1) the emergence of the management education system, (2) the creation of formal university studies and foundation of management/economics faculties (under pre-democratic laws), (3) the structuration and universalization of the management education system (under democratic laws) and (4) the current management education system (after the implementation of the European higher education reform, or Bologna declaration). (1) Emergence of the management education system (up to 1943): The university education system in Spain is one of the oldest in Europe. The University of Salamanca was…
Uses and Misuses of Data
2018
Higher education is awash with data with more coming every year. Much of this is due to accountability reasons and growing interest from stakeholders (internal and external). New technologies have increasingly allowed more powerful analytics and deeper dives into data. However the increasing pressures and new technologies have brought significant questions on how data is used and its relevance. This chapter examines how data is used within higher education and an extended discussion of how it has been misused. The chapter concludes with three suggestions on how institutions can do to reduce the likelihood of the misuse of data and the role of institutional research could play in facilitatin…
