Integrating Keyword Advertising and Dynamic Pricing for an Online Market Place

2014

Keyword Advertising is a main marketing instrument for e-commerce companies in order to generate traffic from search engines on their website. The costs for Keyword Advertising are determined in an auction that is conducted for every single search query, which is entered in by a user. In case of an online market place, each adlink provided by the search engine refers to an ordered list of products on the website of the online market place. Hereby, the price of the product is oftentimes one important criteria for the user when deciding for one or the other product from the list. However, existing models assume the price of products to be exogeneous. By taking into account the prices of linke…

Trends and cycles in U.S. job mobility

2021

Recent studies document a decline in U.S. labor-market fluidity from as early as the 1970s on. Making use of the Annual Social and Economic (ASEC) supplement to the Current Population Survey (CPS), I uncover a pronounced increase in job-to-job mobility from the 1970s to the 1990s, i.e., the annual share of continuously employed job-to-job movers rises from 5.9 percent of the labor force in 1975–1979 to 8.8 percent in 1995–1999. Job-to-job mobility exhibits a downward trend only since the turn of the millennium. In order to provide a formal economic interpretation, I additionally estimate the parameters of the random on-the-job search model. Furthermore, I document that job-to-job mobility h…

Design and interpret the place of present

2018

The contemporary landscape expresses in itself all the contradictions of present time, marked by the lack of a coherent thought about the transformation of places and of a clear aesthetic elaboration. So, the project must reflect not only on the relationship between man and landscape but above on the need to return to a way of dwelling that respects the places. Architecture plays a fundamental role in the reconstruction of coherence of places and reveals their beauty: through its forms, it can set up unprecedented stories of space in places in constant evolution. The thought from which the design process originates must involve the reading and interpretation of the existing places, and proc…

Proteomic analysis of the pinworm Syphacia muris (Nematoda: Oxyuridae), a parasite of laboratory rats

2012

Syphacia muris (Nematoda: Oxyuridae) is a ubiquitous nematode that commonly infects rats in the laboratory which can interfere in the development of biological assays. The somatic extract of S. muris adults collected from infected rats was investigated using a proteomic approach. A shot-gun liquid chromatography/tandem mass spectrometry procedure was used. We used the MASCOT search engine (Matrix-Science) and ProteinPilot software v2.0 (Applied Biosystems) for the database search. A total of 359 proteins were accurately identified from the worms. The largest protein families consisted of metabolic enzymes and those involved in the nucleic metabolism and cell cycle. Proteins of transmembrane…

Access to documentation and training in pathological gambling / Acceso a la documentación y formación en juego patológico

2004

Con objeto de cubrir la necesidad de actualización constante del conocimiento en el área específica del juego patológico en España se desarrolla este artículo como una guía para el acceso rápido y directo a la formación/ información y la búsqueda de bibliografía en este tópico. Para ello, ésta se configura en dos apartados: uno de documentación, que incluye las principales bases de datos, publicaciones periódicas, libros y manuales, así como tesis doctorales, y otro sobre la formación tanto general como continuada. AbstractWe develop this article as a guide for the direct and fast access to the education/information and the bibliographic search, because of the need of constant updating of t…

Asthma diagnosis in infants and preschool children: a systematic review of clinical guidelines.

2019

Background and aim: The definition and diagnosis of asthma are the subject of controversy that is particularly intense in the case of individuals in the first years of life, due to reasons such as the difficulty of performing objective pulmonary function tests or the high frequency with which the symptoms subside in the course of childhood. Since there is no consensus regarding the diagnosis of asthma in preschool children, a systematic review has been carried out. Materials and methods: A systematic search was made of the clinical guidelines published in the last 10 years and containing information referred to the concept or diagnosis of asthma in childhood - including the first years of l…

Diabetes mellitus tipo 1: breve revisión de los principales factores psicológicos asociados

2015

Resumen: La diabetes mellitus tipo 1 (DM1) es una enfermedad crónica ampliamente extendida entre la población infantojuvenil. Suele suponer una sobrecarga significativa en el niño y su familia, modificando aspectos en su estilo de vida, necesarios para cumplimentar las exigencias del tratamiento.Nuestro objetivo es estudiar las principales características psicológicas, familiares y de ajuste a la enfermedad de los niños y adolescentes diagnosticados de DM1, haciendo especial hincapié en los factores psicopatológicos asociados.La metodología empleada ha consistido en una búsqueda bibliográfica sistemática en las principales bases de datos científicas.Debido al impacto biopsicosocial que la D…

Diagrammatic approach to quantum search

2014

We introduce a simple diagrammatic approach for estimating how a randomly walking quantum particle searches on a graph in continuous-time, which involves sketching small weighted graphs with self-loops and considering degenerate perturbation theory's effects on them. Using this method, we give the first example of degenerate perturbation theory solving search on a graph whose evolution occurs in a subspace whose dimension grows with $N$.

Spatial Search by Continuous-Time Quantum Walk with Multiple Marked Vertices

2015

In the typical spatial search problems solved by continuous-time quantum walk, changing the location of the marked vertices does not alter the search problem. In this paper, we consider search when this is no longer true. In particular, we analytically solve search on the "simplex of $K_M$ complete graphs" with all configurations of two marked vertices, two configurations of $M+1$ marked vertices, and two configurations of $2(M+1)$ marked vertices, showing that the location of the marked vertices can dramatically influence the required jumping rate of the quantum walk, such that using the wrong configuration's value can cause the search to fail. This sensitivity to the jumping rate is an is…
