Information Provision in road transport with elastic demand a welfare economic approach
Journal of Transport Economics and Policy, 1996Co-Authors: Richard H M Emmerink, Erik T Verhoef, Peter NijkampAbstract:The objective of this paper is to enhance insight into the welfare economic effects of Information Provision to a group of drivers, and to gain insight into the mechanisms affecting the impact of providing Information. The paper first compares the traditional equilibrium concepts with the methodology proposed. The general model is then presented and the impact of Information Provision equity and efficiency is studied.

the potential of Information Provision in a simulated road transport network with non recurrent congestion
Transportation Research Part C-emerging Technologies, 1995Co-Authors: Rhm Emmerink, Kay W Axhausen, Peter Nijkamp, Piet RietveldAbstract:Abstract This paper analyses the potential of advanced traveller Information systems (ATIS) in a road network in which incidents are generated in a random fashion. A simulation model is applied in which the traffic flows are the aggregation of drivers' decisions. These decisions, in turn, are modelled using boundedly rational principles. The experiments performed focus on the relationship between the network wide performance, the level of market penetration, the quality of the Information, and the en route switching propensity. The results indicate that if drivers behave according to boundedly rational principles without being provided with Information in a road network with non-recurrent congestion, the road network will not be used efficiently in terms of travel time. In these circumstances, ATIS is useful. However, the commercial viability of ATIS might be frustrated by the quickly diminishing additional benefits to equipped drivers. Further, the complexity of the implications of ATIS is stressed by the strong interaction between, on the one hand, the level of market penetration, the quality of the Information and the en route switching propensity and, on the other hand, the network wide performance.

effects of Information in road transport networks with recurrent congestion
Transportation, 1995Co-Authors: Rhm Emmerink, Kay W Axhausen, Peter Nijkamp, Piet RietveldAbstract:This paper aims to gain more insight into the implications of Information Provision to drivers on the performance of road transport networks with recurrent congestion. For this purpose, a simulation program consisting of three components has been written. The first component is the traffic simulation model, the second component is the Information Provision mechanism, and the third component monitors the behavioural decision-making process of the drivers, which is modelled using a utility-based satisficing principle. Three types of Information Provision mechanisms will be considered: Information based upon own-experience, after-trip Information and real-time en route Information. The findings in this paper, obtained in a hypothetical context, underline the important relationship betweenoverreaction, thelevel of market penetration and thequality of the Information. High quality Information allows a high level of market penetration, while low quality Information, even when provided at low levels of market penetration, induces overreaction. Furthermore, real-time en route Information is in particular beneficial during the process leading to a steady state; it reduces the variance in travel time considerably. The paper concludes with a discussion on the market potential of motorist Information systems when commercially marketed.

school libraries political Information and Information literacy Provision findings from a scottish study
Journal of Information Literacy, 2016Co-Authors: Lauren SmithAbstract:This paper presents the findings of research which explored Scottish school libraries’ Information Provision and Information literacy (IL) support in the run-up to two major political events: the 2014 Scottish Independence Referendum (SIR) and the 2015 General UK Parliamentary Election (GE). To do this, the project identified, through an online survey, what political Information seeking secondary school students engaged in through school libraries, what Information Provision and IL support was available to students relating to political issues and events, and what barriers school libraries faced in providing these aspects of political education. It also identified what Information seeking students engaged in, what levels of Information Provision and IL support relating to politics are provided by school libraries, and to explore the perceptions and experiences of library staff relating to work in this area. Analysis of the results indicates that there are mixed levels of Provision across school libraries in Scotland and that this variation may be influenced by inconsistent policies from local councils and individual schools themselves, as well as variations in the experience and views of library staff. Key activities to support young people’s political education are identified, and several reasons library staff do not engage in political work are discussed. The findings are linked to previous research, with a discussion of the need to encourage and support school library staff to contribute to the political education of students alongside teaching staff. Several recommendations for schools and library staff are made, relating to a consideration of the role of school libraries, how they can provide relevant political Information, the importance of clear policies around political Information Provision and the support required for school library workers.

illness perceptions in cancer survivors what is the role of Information Provision
Psycho-oncology, 2013Co-Authors: Olga Husson, Floortje Mols, Melissa S Y Thong, Simone Oerlemans, Adrian A Kaptein, Lonneke V Van De PollfranseAbstract:Background The aim of this study was to provide insight into the relationship between Information Provision and illness perceptions among cancer survivors. Methods All individuals diagnosed with lymphoma, multiple myeloma, endometrial or colorectal cancer between 1998 and 2008, as registered in the Eindhoven Cancer Registry, were eligible for participation. In total, 4446 survivors received a questionnaire including the EORTC-QLQ-INFO25 and the Brief Illness Perception Questionnaire; 69% responded (n = 3080). Results Lymphoma and multiple myeloma patients were most satisfied with the Information they received, and they perceived to having received more Information about their treatment and other services (after care) compared with colorectal and endometrial cancer survivors (p < 0.05). Multiple myeloma patients reported the highest scores (conceptualized their illness as very serious) on the illness perception scales. The perceived receipt of more disease-specific Information was associated with more personal and treatment control and a better understanding of the illness, whereas the perceived receipt of more Information about other services was associated with more negative consequences of the illness on the patients' life, longer perceived duration of illness, less treatment control, more symptoms attributable to the illness, less understanding of, and stronger emotional reaction to the illness (p < 0.05). Satisfaction with the received Information was associated with better illness perception on all subscales, except for personal control (p < 0.05). Conclusion Improving the patients' illness perceptions by tailoring the Information Provision to the needs of patients may help patients to get a more coherent understanding of their illness and will possibly lead to a better health-related quality of life.

the relation between Information Provision and health related quality of life anxiety and depression among cancer survivors a systematic review
Annals of Oncology, 2011Co-Authors: Olga Husson, Floortje Mols, L V Van De PollfranseAbstract:Background: Providing Information that is congruent with patients’ needs is an important determinant for patient satisfaction and might also affect health-related quality of life (HRQoL) and anxiety and depression levels of cancer survivors. Design: The authors systematically reviewed the available literature on the relationship between Information Provision and HRQoL, anxiety and depression. A PubMed literature search for original articles published until February 2010 was carried out. Twenty-five articles, all conducted between 1996 and 2009, which met the predefined inclusion criteria, were subjected to a quality checklist. Results: Satisfied patients, patients with fulfilled Information needs, and patients who experience less Information barriers, in general have a better HRQoL and less anxiety and depression. Out of eight intervention studies that aimed to improve Information Provision, only one showed a positive association with better HRQoL. Conclusion: Health care providers must pay more attention to patient-centred Information Provision. Additional research is needed to make definitive conclusions about Information interventions as most results did not reach statistical significance due to methodological constraints. The quick development of the relatively young research field of patient-reported outcomes in cancer survivorship will make it possible to conduct better quality studies in the future.

Colorectal cancer survivors’ beliefs on nutrition and cancer; correlates with nutritional Information Provision
Supportive Care in Cancer, 2019Co-Authors: Merel R. Veen, Floortje Mols, Lian Smeets, Ellen Kampman, Sandra BeijerAbstract:Purpose To investigate CRC survivors’ beliefs on nutrition and cancer and the association with nutritional Information Provision by (kind and number) of health professionals and to inquire about foods that CRC survivors believed either had a positive or negative influence on their cancer. Methods A total of 326 CRC survivors of an ongoing prospective cohort study filled out questionnaires 1 month after surgery on whether they had received nutritional Information from health professionals. Also, their beliefs that nutrition influences (1) feelings of well-being, (2) complaints after treatment, (3) recovery and (4) cancer recurrence were investigated. Prevalence ratios were calculated (using Cox proportional hazard regression analysis) to study associations between Information Provision and the four beliefs adjusted for age, gender and cancer stage. Results Sixty-two percent of respondents received Information about nutrition from one or more health professionals. Most respondents who received Information strongly believe nutrition influences feelings of well-being (59%) and recovery after cancer (62%). Compared with those who did not receive Information, respondents who received Information from three professionals showed the strongest beliefs on the influence of nutrition on complaints after treatment (PR 3.4; 95% CI 1.6–7.4), recovery after treatment (PR 2.0; 95% CI 1.2–3.3) and recurrence (PR 2.8; 95% CI 1.3–6.2). Conclusion Nutritional Information Provision by health professionals positively influences the beliefs of CRC survivors on the influence of nutrition on cancer outcomes: stronger beliefs occur when respondents received Information from three health professionals.
