Lingvistiski-pragmatiskā nozīme reklāmas stratēģijās
2018
Pašreizējā bakalaura darba mērķis ir raksturot, kā un kādas reklāmas stratēģijas tiek piemērotas reklāmām "Starbucks" un "Costa Coffee", kā arī aprakstīt pragmatiskos un semantiskos elementus, kas ietverti katrā gadījumā, un tā pārstāvētajā stratēģijā. Bakalaura darba galvenais mērķis ir apspriest reklāmu pamatjēdzienu, jo uzņēmumi mēdz uzrādīt informāciju, ko var saprast vairākos veidos. Reklāma ir mārketinga stratēģija, kurai piemīt spēja parādīt vairākas nozīmes, lietojot vārdu krājumu, vizuālos materiālus un stratēģijas, kas palīdz uzrunāt konkrētu sabiedrības daļu. Datu analīzes metode ir gadījumu izpēte, analīzei tika izvēlēti divi lieli un populāri uzņēmumi ("Starbucks", "Costa Coffe…
Metabolic flux understanding of Pichia pastoris grown on heterogenous culture media
2014
[EN] Within the emergent field of Systems Biology, mathematical models obtained from physical chemical laws (the so-called first principles-based models) of microbial systems are employed to discern the principles that govern cellular behaviour and achieve a predictive understanding of cellular functions. The reliance on this biochemical knowledge has the drawback that some of the assumptions (specific kinetics of the reaction system, unknown dynamics and values of the model parameters) may not be valid for all the metabolic possible states of the network. In this uncertainty context, the combined use of fundamental knowledge and data measured in the fermentation that describe the behaviour…
Modelling a real situation with tablets: the ball experiment
2015
[EN] In this study we present an experience carried out in an 11th grade class. We use a teaching model designed to work the concepts of family of functions and parameter through the modelling. This model has the characteristic that the data are obtained by students in classroom using tablets and it includes elements that allow them to manage the modelling process. The analysis of the results revealed that the realization of a previous qualitative analysis of the phenomenon studied and the students’ knowledge about the families of functions and the meaning of the parameters are key elements in the management and control of the entire process. Besides, we obtained information about the stude…
Cyber Situational Awareness in Critical Infrastructure Organizations
2021
The capability related to cybersecurity plays an ever-growing role on overall national security and securing the functions vital to society. The national cyber capability is mainly composed by resilience of companies running critical infrastructures and their cyber situational awareness (CSA). According to a common view, components of critical infrastructures become more complex and interdependent on each other and, as a consequence, ramifications of incidents multiply. In practice, the actions relate to developing better CSA and understanding of a critical infrastructure organization. The aim is to prepare for incidents and their management in a whole-of-society approach. The arrangement i…
Modelos emergentes en un primer curso de economía y administración
2013
[EN] In this paper we present an outline of an ongoing research in which we intend to investigate on the teaching of the modelling process and families of functions in the context of a course in Economics and Management. Specifically, we introduce some of the theoretical foundations that support the research and we present an example of one of the activities that we are designing for teaching.
Phylogenetic relationship among genera of Polymorphidae (Acanthocephala), inferred from nuclear and mitochondrial gene sequences.
2013
Abstract Acanthocephalans of the family Polymorphidae Meyer, 1931 are obligate endoparasites with complex life cycles. These worms use vertebrates (marine mammals, fish-eating birds and waterfowl) as definitive hosts and invertebrates (amphipods, decapods and euphausiids) as intermediate hosts to complete their life cycle. Polymorphidae has a wordwide distribution, containing 12 genera, with approximately 127 species. The family is diagnosed by having a spinose trunk, bulbose proboscis, double-walled proboscis receptacle, and usually four to eight tubular cement glands. To conduct a phylogenetic analysis, in the current study sequences of the small (18S) and large-subunit (28S) ribosomal RN…
Proteomic analysis of Parietaria judaica pollen and allergen profiling by an immunoproteomic approach
2010
Parietaria judaica pollen is a common cause of airway allergic disease in the Mediterranean area. Proteome analysis of mature Parietaria judaica pollen by two-dimensional gel electrophoresis (2-DE) and mass spectrometry has established the first reference proteome map of this weed. Proteins involved in a variety of cellular functions as well as the occurrence of allergens were detected. By using 2-DE and immunoblotting with sera from Parietaria judaica allergic patients we obtained a more detailed characterization of Parietaria judaica allergen profile so to improve our comprehension of the pathogenesis of pollen-induced allergic reaction.
Statistical properties of the site-frequency spectrum associated with lambda-coalescents.
2013
Abstract Statistical properties of the site-frequency spectrum associated with Λ-coalescents are our objects of study. In particular, we derive recursions for the expected value, variance, and covariance of the spectrum, extending earlier results of Fu (1995) for the classical Kingman coalescent. Estimating coalescent parameters introduced by certain Λ-coalescents for data sets too large for full-likelihood methods is our focus. The recursions for the expected values we obtain can be used to find the parameter values that give the best fit to the observed frequency spectrum. The expected values are also used to approximate the probability a (derived) mutation arises on a branch subtending a…
Envelopes of open sets and extending holomorphic functions on dual Banach spaces
2010
We investigate certain envelopes of open sets in dual Banach spaces which are related to extending holomorphic functions. We give a variety of examples of absolutely convex sets showing that the extension is in many cases not possible. We also establish connections to the study of iterated weak* sequential closures of convex sets in the dual of separable spaces.
