Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning systems, air temperature is the parameter that is normally controlled whilst others are assumed to have values within the specified ranges at the design stage. In Fanger’s double heat balance equation, thermal radiation factor appears as the mean radiant temperature (MRT), however, its impact on thermal comfort is often ignored. This paper discusses the impacts of the thermal radiation field which takes the forms of mean radiant temperature and radiation asymmetry on thermal comfort, building energy consumption and air-conditioning control. Several conditions and applications in which the effects of mean radiant temperature and radiation asymmetry cannot be ignored are discussed. Several misinterpretations that arise from the formula relating mean radiant temperature and the operative temperature are highlighted, coupled with a discussion on the lack of reliable and affordable devices that measure this parameter. The usefulness of the concept of the operative temperature as a measure of combined effect of mean radiant and air temperatures on occupant’s thermal comfort is critically questioned, especially in relation to the control strategy based on this derived parameter. Examples of systems which deliver comfort using thermal radiation are presented. Finally, the paper presents various options that need to be considered in the efforts to mitigate the impacts of the thermal radiant field on the occupants’ thermal comfort and building energy consumption.

From the article: "Abstract Maintenance processes of Dutch housing associations are often still organized in a traditional manner. Contracts are based on lowest price instead of ‘best quality for lowest price’ considering users’ demands. Dutch housing associations acknowledge the need to improve their maintenance processes in order to lower maintenance cost, but are not sure how. In this research, this problem is addressed by investigating different supply chain partnering principles and the role of information management. The main question is “How can the organisation of maintenance processes of Dutch housing associations, in different supply chain partnering principles and the related information management, be improved?” The answer is sought through case study research."

Background: Revealing tacit knowledge often is seen as very valuable for organizations, although it is usually challenging to enunciate and share this type of knowledge. Methods: This study uses a participatory design and the application of a board gaming simulation as instruments to extract tacit knowledge. To illustrate this application, the gaming simulation is played with entrepreneurs from horticulture. Horticulture represents a complex social system where tacit knowledge plays a major role in the trade process. A participatory design process is used to explore whether the design and play of gaming simulations enable participants to explicate their tacit knowledge. Participants’ participation in designing the gaming simulation explicated that reconstructing reality was a prerequisite for their commitment. Results: The results from playing simulation sessions show that participants were able to: (1) narrow down the anecdotic behaviour to a few factors; (2) to structure these factors; (3) explore how these factors relate to trade barriers and (4) to explain which tactics are applied to foster trade. Conclusion: The educational value of this study is that it helped entrepreneurs in understanding complex real-life situations.

Many global challenges cannot be addressed by one single actor alone. Achieving sustainability requires governance by state and non-state market actors to jointly realise public values and corporate goals. As a form of public-private governance, voluntary standards involving governments, non-governmental organisations and companies have gained much traction in recent years and have been in the limelight of public authorities and policymakers. From a firm perspective, sustainability standards can be a way to demonstrate that they engage in corporate social responsibility (CSR) in a credible way. To capitalise on their CSR activities, firms need to ensure their stakeholders are able to recognise and assess their CSR quality. However, because the relative observability of CSR is low and since CSR is a contested concept, information asymmetries in firm-stakeholder relationships arise. Adopting CSR standards and using these as signalling devices is a strategy for firms to reduce these information asymmetries, by revealing their true CSR quality. Against this background, this article investigates the voluntary ISO 26000 standard for social responsibility as a form of public-private governance and contends that, despite its objectives, this standard suffers from severe signalling problems. Applying signalling theory to the ISO 26000 standard, this article takes a critical stance towards this standard and argues that firms adhering to this standard may actually emit signals that compromise rather than enhance stakeholders' ability to identify and interpret firms' underlying CSR quality. Consequently, the article discusses the findings in the context of public-private governance, suggests a specification of signalling theory and identifies avenues for future research.

accepted abstract Quis14 conference Field findings show that value dimensions in legal services are functional, social and emotional. The last category emerges not only within but also outside the interaction with the lawyer. Recommendation of others or the trackrecord of lawyers for example, which play a role before or after the service, contribute to emotional values like trust and reassurance and help clients to reduce the perceived purchase risk, which is inherent to the nature of credence services. Also due to the credential character of legal services we conclude that not only professional skills but also service aspects as client involvement play an important role in the emergence of value because professional skills are difficult to judge even by routine buyers.

Following the rationale of the current EU legal framework protecting personal data, children are entitled to the same privacy and data protection rights as adults. However, the child, because of his physical and mental immaturity, needs special safeguards and care, including appropriate legal protection. In the online environment, children are less likely to make any checks or judgments before entering personal information. Therefore, this paper presents an analysis of the extent to which EU regulation can ensure children’s online privacy and data protection.

Abstract The emergence of new technologies such as mp3 and music streaming, and the accompanying digital transformation of the music industry, have led to the shift and change of the entire music industry’s value chain. While music is increasingly being consumed through digital channels, the number of empirical studies, particularly in the field of music copyright in the digital music industry, is limited. Every year, rightsholders of musical works, valued 2.5 billion dollars, remain unknown. The objectives of this study are twofold: First to understand and describe the structure and process of the Dutch music copyright system including the most relevant actors within the system and their relations. Second to apply evolutionary economics approach and Values Sensitive Design method within the context of music copyright through positive-empirical perspective. For studies of technological change in existing markets, the evolutionary economics literature provides a coherent and evidence-based foundation. The actors are generally perceived as being different, for example with regard to their access to information, their ability to handle information, their capital and knowledge base (asymmetric information). Also their norms, values and roles can differ. Based on an analysis of documents and held expert interviews, we find that the collection and distribution of the music copyright money is still based on obsolete laws, neoclassical paradigm and legacy IT-system. Finally, we conclude that the rightsholders are heterogenous and have asymmetrical information and negotiating power. The outcomes of this study contribute to create a better understanding of impact of digitization of music copyright industry and empower the stakeholders to proceed from a more informed perspective on redesigning and applying the future music copyright system and pre-digital norms and values amongst actors.

When an adult claims he cannot sleep without his teddy bear, people tend to react surprised. Language interpretation is, thus, influenced by social context, such as who the speaker is. The present study reveals inter-individual differences in brain reactivity to social aspects of language. Whereas women showed brain reactivity when stereotype-based inferences about a speaker conflicted with the content of the message, men did not. This sex difference in social information processing can be explained by a specific cognitive trait, one's ability to empathize. Individuals who empathize to a greater degree revealed larger N400 effects (as well as a larger increase in γ-band power) to socially relevant information. These results indicate that individuals with high-empathizing skills are able to rapidly integrate information about the speaker with the content of the message, as they make use of voice-based inferences about the speaker to process language in a top-down manner. Alternatively, individuals with lower empathizing skills did not use information about social stereotypes in implicit sentence comprehension, but rather took a more bottom-up approach to the processing of these social pragmatic sentences.
