  5. Management and performance features of cancer centers in Europe: A fuzzy-set analysis

    Wind, Anke; Lobo, Mariana Fernandes; Dijk, Joris van; Lepage-Nefkens, Isabelle; Laranja-Pontes, Jose; Conceicao Goncalves, Vitor da; Harten, Wim van; Rocha-Goncalves, Francisco Nuno
    The specific aim of this study is to identify the performance features of cancer centers in the European Union by using a fuzzy-set qualitative comparative analysis (fsQCA). The fsQCA method represents cases (cancer centers) as a combination of explanatory and outcome conditions. This study uses data on seven centers from a European benchmarking project: BENCH-CAN. The fsQCA uses the net income and productivity as the outcome conditions and five explanatory conditions: the level of dedication to R&D, annual budget level, size, type, and whether the center is a comprehensive cancer center. Despite the modest number of cases, the study successfully...

  6. Who Am I? A Life Story Intervention for Persons With Intellectual Disability and Psychiatric Problems

    Westerhof, Gerben J.; Beernink, Janny; Sools, Anneke
    This article describes an innovative intervention based on narrative and life review therapy that is tailored to people with intellectual disability (ID) and psychiatric problems. The current study provides a first evaluation of the intervention. A symptom checklist (SCL-90) was used in a pre- and post-follow-up design, and a qualitative evaluation of the intervention was carried out with 25 participants. Results showed large changes in psychiatric symptoms, in particular on depression, anxiety, obsessive-compulsive disorder, and interpersonal sensitivity. Participants were mainly positive in their general explicit evaluations of the therapy as well as on personal learning points, intervention-specific, group-related, and therapist-related...

  7. European Water Footprint Scenarios for 2050

    Ercin, A.E.; Hoekstra, A.Y.
    This study develops water footprint scenarios for Europe for 2050, at the country level, based on projections regarding population and economic growth, production and trade patterns, consumption patterns (diets and bioenergy use) and technological development. The objective is to estimate possible future changes in the green, blue and grey water footprint (WF) of production and consumption, to analyze the main drivers of projected changes and to assess Europe's future dependence on water resources elsewhere in the world. We develop four scenarios, considering globalization versus regional self-sufficiency, and development driven by economic objectives versus development driven by social and environmental objectives....

  8. Integration of unobserved effects in generalised transport access costs of cycling to railway stations

    La Paix Puello, L.C.; Geurs, K.T.
    This paper focuses on the spatial influence of High-Speed Rail stations, based on the notion of catchment area. Given the features of High-Speed Rail, its operations can and must serve a role beyond the station and the city in which it is located. Using a spatial systemic approach, this paper proposes a method to analyse the factors that may affect the size and shape of the catchment areas according to the relationship between distance and ridership. This study employs data from surveys of six stations of the Spanish high-speed rail system to apply the model and demonstrates that the context...

  10. Translating patient reported outcome measures: methodological issues explored using cognitive interviewing with three rheumatoid arthritis measures in six European languages

    Hewlett, Sarah E.; Nicklin, Joanna; Bode, Christina; Carmona, Loretto; Dures, Emma; Engelbrecht, Matthias; Hagel, Sofia; Kirwan, John R.; Molto, Anna; Redondo, Marta; Gossec, Laure
    Objective. Cross-cultural translation of patient-reported outcome measures (PROMs) is a lengthy process, often performed professionally. Cognitive interviewing assesses patient comprehension of PROMs. The objective was to evaluate the usefulness of cognitive interviewing to assess translations and compare professional (full) with non-professional (simplified) translation processes. Methods. A full protocol used for the Bristol RA Fatigue Multi-dimensional Questionnaire and Numerical Rating Scale (BRAF-MDQ, BRAF-NRS) was compared with a simplified protocol used for the RA Impact of Disease scale (RAID). RA patients in the UK, France, the Netherlands, Germany, Spain and Sweden completed the PROMs during cognitive interviewing (BRAFs in the UK were...

  11. Impaired Mood in Headache Clinic Patients: Associations With the Perceived Hindrance and Attainability of Personal Goals

    Ciere, Yvette; Visser, Annemieke; Lebbink, John; Sanderman, Robbert; Fleer, Joke
    Background Headache disorders are often accompanied by impaired mood, especially in the headache clinic population. There is a large body of literature demonstrating that an illness or disability may affect the way in which patients perceive their personal goals and that the perception that the attainability of goals is hindered by the illness is a risk factor for impaired mood. However, empirical evidence regarding the extent to which goals are hindered or less attainable as a result of a headache disorder, and how that is related to mood, is currently lacking. Objective The aim of this cross-sectional study was to examine associations between...

  12. The responsibility to prevent, the duty to educate

    Lederman, Zohar; Cernat, Alexandra; Ferri, Eleonora Gregori; Galbo, Franco; Levi-Setti, mar Micol Andrea; Mertens, M.; Moore, Bryanna; Riklikiene, Olga; Vescio, Jamie; Chamberlin, Sheena Eagan

  13. Joint Modeling of Ability and Differential Speed Using Responses and Response Times

    Fox, Jean-Paul; Marianti, Sukaesi
    With computerized testing, it is possible to record both the responses of test takers to test questions (i.e., items) and the amount of time spent by a test taker in responding to each question. Various models have been proposed that take into account both test-taker ability and working speed, with the many models assuming a constant working speed throughout the test. The constant working speed assumption may be inappropriate for various reasons. For example, a test taker may need to adjust the pace due to time mismanagement, or a test taker who started out working too fast may reduce the...

  14. The COPD-SIB: a newly developed disease-specific item bank to measure health-related quality of life in patients with chronic obstructive pulmonary disease

    Paap, Muirne C.S.; Lenferink, Lonneke I.M.; Herzog, Nadine; Kroeze, Karel; Palen, Job van der
    Background Health-related quality of life (HRQoL) is widely used as an outcome measure in the evaluation of treatment interventions in patients with chronic obstructive pulmonary disease (COPD). In order to address challenges associated with existing fixed-length measures (e.g., too long to be used routinely, too short to ensure both content validity and reliability), a COPD-specific item bank (COPD-SIB) was developed. Methods Items were selected based on literature review and interviews with Dutch COPD patients, with a strong focus on both content validity and item comprehension. The psychometric quality of the item bank was evaluated using Mokken Scale Analysis and parametric Item Response Theory,...

  15. Doxing: a conceptual analysis

    Douglas, David M.
    Doxing is the intentional public release onto the Internet of personal information about an individual by a third party, often with the intent to humiliate, threaten, intimidate, or punish the identified individual. In this paper I present a conceptual analysis of the practice of doxing and how it differs from other forms of privacy violation. I distinguish between three types of doxing: deanonymizing doxing, where personal information establishing the identity of a formerly anonymous individual is released; targeting doxing, that discloses personal information that reveals specific details of an individual’s circumstances that are usually private, obscure, or obfuscated; and delegitimizing...

  16. Do the rich get digitally richer? Quantity and quality of support for digital engagement

    Helsper, Ellen J.; Deursen, Alexander J.A.M. van
    This paper asks what predicts having access to and using social support networks that might help an individual in using the Internet. Following the course taken by the digital divide or digital inclusion research, this paper uses socio-cultural, socio-economic, social, and digital indicators to predict access to and the type of potential and actual social support networks that might help an individual in using the Internet. In addition, the paper examines the quality of the support received which is neglected in most investigations that mainly focus on quantitative indicators of support. The study draws on a representative survey conducted in...

  17. Party membership in Europe: Testing party-level explanations of decline

    Kölln, Ann-Kristin
    Research on party membership development commonly reports figures aggregated to the country level and/or using only a few time-points. While these choices may be appropriate for certain research questions, they nevertheless hide major differences between parties and conceal short-term fluctuations. Additionally, they are inappropriate for studying individual party trajectories. This is necessary, however, to better describe and ultimately explain the phenomenon of membership decline. The article analyses in total 1653 observations across 47 parties in six western European countries between 1960 and 2010 to test hypotheses pertaining to individual party membership development. Using multilevel modelling and time-series analyses, the results...

  18. A meta-analysis of different HR-enhancing practices and performance of small and medium sized firms

    Rauch, Andreas; Hatak, Isabella
    The role of human capital has received considerable attention in research on small and medium sized firms. However, much uncertainty remains as to how practices that enhance human resources (HR) affect the performance of small and medium sized firms, whether some practices have stronger effects than others, and which contingencies influence these effects. Relying on the framework proposed by Subramony (2009), we propose that small and medium sized firms need to implement HR practices that focus on enhancing skills, motivation, and empowerment. The results of our meta-analysis comprising 56 studies that focused on small and medium sized enterprises (SME) indicated...

  19. Teachers’ professional reasoning about their pedagogical use of technology

    Heitink, M.; Voogt, J.M.; Verplanken, L.; Braak, J. van; Fisser, P.
    This study focused on teachers’ reasoning about the use of technology in practice. Both teachers’ professional reasoning and their technology use were investigated. Through video cases, 157 teachers demonstrated their technology use in practice and commented on the reasoning behind their actions. Results show that most technology use was intended to strengthen both pedagogy and subject matter, or else pedagogy alone. Reasons addressed making learning attractive for students, realizing educational goals and facilitating the learning process. The majority of teachers’ technology use in practice shows aspects of the knowledge transfer model of teaching. Most technology tools were used to support...

  20. Healthy package, healthy product? Effects of packaging design as a function of purchase setting

    Rompay, Thomas J.L. van; Deterink, Florien; Fenko, Anna
    Inspired by research testifying to the influence of visual packaging appearance and meaning portrayal on food evaluation, here it is argued that effects of packaging design vary depending on purchase context. Realistic packaging variants for a fictitious yoghurt brand varying in health connotation were designed. Data were collected during two field studies in the entrance halls of a discount supermarket visited by price sensitive buyers and a green supermarket frequented by organic buyers respectively. Results from a taste session in which shoppers tasted an identical yoghurt variant from either one of the two package variants revealed that packaging design influenced...
