  • Dynamic lighting systems in psychogeriatric care facilities in the Netherlands : A quantitative and qualitative analysis of stakeholders’ responses and applied technology
  • 2015

    • Long-term care facilities are currently installing dynamic lighting systems with the aim to improve the well-being and behaviour of residents with dementia. The aim of this study was to investigate the implementation of dynamic lighting systems from the perspective of stakeholders and the performance of the technology. Therefore, a questionnaire survey was conducted with the management and care professionals of six care facilities. Moreover, light measurements were conducted in order to describe the exposure of residents to lighting. The results showed that the main reason for purchasing dynamic lighting systems lied in the assumption that the well-being and day/night rhythmicity of residents could be improved. The majority of care professionals were not aware of the reasons why dynamic lighting systems were installed. Despite positive subjective ratings of the dynamic lighting systems, no data were collected by the organizations to evaluate the effectiveness of the lighting. Although the care professionals stated that they did not see any large positive effects of the dynamic lighting systems on the residents and their own work situation, the majority appreciated the dynamic lighting systems more than the old situation. The light values measured in the care facilities did not exceed the minimum threshold values reported in the literature. Therefore, it seems illogical that the dynamic lighting systems installed in the researched care facilities will have any positive health effects.

  • Performance of personally worn dosimeters to study non-image forming effects of light Assessment methods
  • 2017

    • When determining the effects of light on human beings, it is essential to correctly measure the effects, and to correctly measure the adequate properties of light. Therefore, it is important to know what is being measured and know the quality of the measurement devices. This paper describes simple methods for identifying three quality indices; the directional response index, the linearity index and the temperature index. These indices are also checked for several commonly used portable light measurement devices. The results stresses what was already assumed, the quality and the outcome of these devices under different circumstances were very different. Also, the location were these devices are normally worn has an impact on the results. The deviation range between worn vertically at eye level and the wrist is between 11% (outdoor) to 27% (indoor). The smallest deviation, both in indoor and outdoor, was found when the device was placed on the sides of the eye (7%).

  • Shedding a light on phototherapy studies with people having dementia : A critical review of the methodology from a light perspective
  • 2016
  • Ingår i: American Journal of Alzheimer’s Disease and Other Dementia. - Sage Publications. - 1533-3175. ; 31:7, s. 551-563

    • Light therapy is applied to older people with dementia as a treatment to reset the biological clock, to improve the cognitive functioning, and to reduce behavioral symptoms. Although the methodological quality of light therapy studies is essential, many aspects concerning the description of the lighting applied are missing. This study reviewed light therapy studies concerning the effects on people with dementia as a way to check the methodological quality of the description of light from a light engineering perspective. Twelve studies meeting the inclusion criteria were chosen for further analysis. Each study was scored on a list of aspects relevant to a proper description of lighting aspects. The overview demonstrates that the overall quality of the methodologies is poor. The studies describe the lighting insufficiently and not in the correct metrics. The robustness of light therapy studies can be improved by involving a light engineer or specialist.

  • Constructing (Il)Legitimate Democracy Populism and Power Concentration in Newspaper Discourse on Venezuela
  • 2014
  • Ingår i: tripleC (cognition, communication, co-operation): Journal for a Global Sustainable Information Society / Unified Theory of Information Research Group. - 1726-670X. ; 12:2, s. 802-821
  • Tidskriftsartikel (refereegranskat)abstract
    • Despite scholarly consensus about the importance of the media for democracy, scant attention has been paid to what democracy means to journalistic discourse and how discourses on democracy are interrelated with legitimacy. The aim of this paper is to explore how (il)legitimate democracy is constructed in newspaper discourse. By using critical discourse analysis (CDA), this paper examines foreign news items about Venezuela, a country that under the presidency of Hugo Chávez has challenged the dominant global political and economic orders. The analysis section focuses on two discourses about the Venezuelan government: the constructions of populism  and power concentration, which serve to mark deviance from what is perceived as a legitimate democracy. This paper argues that a liberal perception of democracy constitutes a central framework for the construction of (il)legitimate democracy, which is revealed not least by news discourse’s focus on what is morally unacceptable political conduct according to liberal democratic norms. In this respect, the media discourse serves to denounce potential abuses of governmental power but fail to recognize democracy in the context of a social struggle against the effects of neoliberalism and capitalism. In this case, the news media is hegemonic in the Gramscian sense, because it provides a framework of democracy that remains within the dominant economic and political structures.

  • First hegemony, then democracy on ideology and the media discourse on the coup against Hugo Chávez
  • 2012
  • Ingår i: OBS - Observatorio. - 1646-5954. ; 6:3, s. 105-128
  • Tidskriftsartikel (refereegranskat)abstract
    • This study examines the media discourse on the 2002 coup d’état against the government of Hugo Chávez in Venezuela, with the aim of exploring how ideology in media discourse helps construct democracy in a Latin American political context. Critical discourse analysis is used to examine written pieces from Dagens Nyheter (Sweden), El País (Uruguay), and the New York Times (US). The study finds that the discourse on the overthrow and the events preceding it constructs the coup as a potential victory for democracy and as the definitive end of Chávez. However, after the failure of the coup and the reinstallation of Chávez one can perceive discursive renegotiations, such as the publishing of non-fundamental criticism of the overthrow. The study argues that the media discourse on the coup displays a highly relativistic attitude towards democracy, which serves the interests of the elite classes in Venezuela and of US hegemony in global politics. The article also argues that the flexibility of the discourse at hand shows the need for a detailed analysis of how ideology is (re)formed in media discourse.

  • News for global sustainability? : Reifying and othering social inequality in news
  • 2016
  • Konferensbidrag (refereegranskat)abstract
    • This paper discusses news journalism about inequality from a critical point of view, with the aim of contributing to the critical theorization of the relationship between journalism and sustainability. Sustainability and journalism on social inequality are perceived as intersecting in at least two ways. On one level, journalism can serve sustainable development by providing high-quality content that can help citizens to better understand the causes behind social inequality and how it can be overcome. On another level, journalism would itself gain much from sustainable development on a global level, since that would provide a good ground for a high-quality journalism characterized by its professional and democratic ethics rather than one that is strained by market-logics. The paper focuses on reification and problematizes the ways in which social inequality is reified in news journalism. Basing the argumentation on examples from international journalism, it is argued that although the existence of social inequality in a specific country can be acknowledged in the reporting – for example by the reference to rich and poor people and rich and poor geographic spaces – the social, political and historical causes of this inequality remain abstracted. In this sense, reification provides a rather objectivist account on inequality, which in turn limits the critique of the mechanisms that lie behind it. On the long run such constructions serve the legitimation of social inequality, which indeed ought to be seen as a sustainability problem. The paper also argues that for a more sustainable journalism to take place, a shift in the attitude towards social inequality and sustainable development must take place in the broader sociocultural context that surrounds journalism.

  • Through Eurocentric logics The construction of difference in foreign news discourse on Venezuela
  • 2016
  • Ingår i: Journal of Language and Politics. - 1569-2159. ; 15:1, s. 94-115
  • Tidskriftsartikel (refereegranskat)abstract
    • This study aims to explore the construction of difference in foreign news discourse on culturally similar but politically different non-Western subjects. Applying critical discourse analysis (CDA) together with a critique of Eurocentrism, the study examines difference in newspaper constructions of government supporters and oppositional groups in Venezuela. Discursive differences are evident in the strategies used for constructing the two groups with regard to political rationality and violence. Government supporters are associated with social justice, Venezuela’s poor, dogmatic behavior, and the use of political violence. The opposition, in contrast, is constructed as following a Western democratic rationale that stresses anti-authoritarianism. This group is primarily associated with victims of violence. While the opposition is conveyed as being compatible with Eurocentric values and practices, government supporters to great extent deviate from these norms. Such constructions serve to legitimize politico-ideological undercurrents of Eurocentrism, as the defense of liberalism.
