Characterization of a cryogenic ion guide at IGISOL

2012

A small volume cryogenic ion guide has been characterized at the IGISOL facility, Jyvaskyla, as a prototype to verify whether there are any major obstacles to the use of high-density cryogenic helium gas for the stopping and extraction of high-energy ions from a large volume cryogenic ion catcher. The expected temperature scaling of the mass flow through the ion guide has been confirmed, showing that for the same helium density, the differential pumping requirements are less stringent for cryogenic operation. At 90 K a clear reduction in the mass-analyzed impurities is achieved, although lower temperatures are required to freeze out oxygen and nitrogen. This is supported by the reduction in…

‘You know that collaboration works when … ’ identifying the features of successful collaboration on behalf of children with disabilities in early chi…

2017

ABSTRACTThe purpose of this study was to identify features of successful collaboration among professionals and parents involved in supporting children with disabilities in early childhood education and care. The study employed a multiple-case study design comprising 6 cases and 30 adult participants, who were interviewed regarding their collaboration on behalf of 6 children with significant disabilities ranging in age from 3 to 5 years. Applying a system-theoretical approach, analysis led to the development of a framework based on the concepts of ‘internal’ and ‘external’ features of collaboration. Whereas internal aspects refer primarily to the interpersonal interactions of parents and pro…

Cell-cell recognition system in gorgonians: description of the basic mechanism

1983

The dissociation of the gorgonian Eunicella cavolinii (Koch) into single cells was successfully accomplished. These cells readily formed aggregates of a size of 2 100 μm during incubation in roller tubes; no aggregate formation was observed in non-rotating Petri dishes. The formation of aggregates was not influenced by Ca++, urea or trypsin; it was also independent of temperature (4° to 30°C) and pH (5.5–9.0). The intercellular material of the gorgonian contains a galactose-specific lectin, as determined by double diffusion experiments and haemagglutination inhibition experiments using a series of galactoglycoconjugates. This lectin converted the aggregation-susceptible cells to aggregation…

Remote sensing:A case for moving space data towards the public good

2008

This paper discusses whether current international and national regulation of remote sensing activities achieves a true balance between proprietary interests of producers of remote sensing data and information and the needs of the community in accessing that data and information. By subjecting remote sensing data to general copyright restrictions that are often coupled with exclusive licences, irrespective of type or use of data and/or information, the development of important secondary information markets could be negatively hampered. In the long run, over-regulating access to space data may prove counter-productive in the information age. Using examples of different modes of information d…

The signaling effects of central bank tone

2021

Abstract Does policymakers’ choice of words matter? We assess empirically whether the tone of FOMC statements contains useful information for financial market participants and explore the nature of the information conveyed. We quantify central bank tone using computational linguistics. We find that the tone of FOMC statements explains monetary surprises beyond FOMC information released on policy announcement days such as policymakers’ forecasts and votes. We also find that the FOMC tone matters more around monetary cycle turning points. We show that the tone of policy statements also helps predict future policy decisions. Our findings suggest that the central bank tone may be one of the veh…

Determinantes del comportamiento de queja y su importancia en la segmentación de clientes insatisfechos

2008

ResumenEsta investigación de carácter exploratorio aborda el proceso de formación del comportamiento de queja utilizando el proceso de segmentación de clientes. Consideramos que dicho comportamiento agrupa dos tipos de respuestas a la insatisfacción: las respuestas de queja y las respuestas privadas. Nuestro objetivo es conocer la capacidad que tiene la intensidad de la insatisfacción y otras variables relevantes de la literatura en la discriminación de segmentos de consumidores, con el propósito de estudiar sus comportamientos y características. La metodología de análisis CHAID ha permitido segmentar la muestra en diferentes grupos identificando los principales antecedentes de ambos tipos …

Influence of online transparency on efficiency. Analysis of spanish NGDOs

2020

This study examines (a) whether nongovernmental development organizations (NGDOs) disseminate relevant information for their stakeholders through their web pages, information that after being reviewed and evaluated by external organizations such as the Spanish Coordinator of Development NGO or Lealtad Foundation, allowed these NGDOs to obtain a seal of transparency and (b) whether their level of transparency influences efficiency. To determine online transparency, web pages of seal-approved NGDOs were reviewed to assess the availability of relevant information. This paper uses data envelopment analysis to assess the efficiency using an input orientation. To determine the influence of online…

Culture and team production

2018

Abstract This paper addresses theoretically the question whether culture has an effect on economic performance in team production, and what would be an optimal team culture. The members of a team are guided both by economic incentives and by personal norms, weighed according to their prevailing level of materialism. We assume that personal norms evolve following a dynamic driven by a combination of psychological mechanisms such as consistency and conformism. The different vectors of materialism, consistency and conformism shared by the group result in a continuum of cultures characterized by different combinations of individualism and collectivism. Team culture turns out to be a fundamental…

Diseño gráfico para formar al profesorado de primaria

2021

Educar en diseño es probablemente la base para una predisposición social hacia la creatividad y la innovación. Presentamos los resultados de una investigación desarrollada en la práctica universitaria, formulada metodológicamente como estudio de caso. Incorporamos la práctica del diseño gráfico al currículum formativo de Maestro/a en Educación Primaria. Si queremos que la ciudadanía aprecie el diseño, conviene preparar al profesorado. Para lograr este acercamiento al diseño gráfico planteamos un taller en el que cada participante elabora su propio exlibris. Los resultados positivos nos animan a continuar con este tipo de iniciativas que aglutinan diseño, patrimonio, identidad e inclusión. E…
