Traditional information systems for crisis response and management are centralized systems with a rigid hierarchical structure. Here we propose a decentralized system, which allows citizens to play a significant role as information source and/or as helpers during the initial stages of a crisis. In our approach different roles are assigned to citizens. To be able to designate the different roles automatically our system needs to generate appropriate questions. On the basis of information theory and a restricted role ontology we formalized the process of question generation. Three consecutive experiments were conducted with human users to evaluate to what extent the questioning process resulted in appropriate role determination. The result showed that the mental model of human users does not always comply with the formal model underpinning the questions generation process.

A common strategy to assign keywords to documents is to select the most appropriate words from the document text. One of the most important criteria for a word to be selected as keyword is its relevance for the text. The tf.idf score of a term is a widely used relevance measure. While easy to compute and giving quite satisfactory results, this measure does not take (semantic) relations between words into account. In this paper we study some alternative relevance measures that do use relations between words. They are computed by defining co-occurrence distributions for words and comparing these distributions with the document and the corpus distribution. We then evaluate keyword extraction algorithms defined by selecting different relevance measures. For two corpora of abstracts with manually assigned keywords, we compare manually extracted keywords with different automatically extracted ones. The results show that using word co-occurrence information can improve precision and recall over tf.idf.

The presentation of management information on screens and paper is aimed at the initiation of control actions in order to bring about predefinied goals. The terms and concepts used in this control information can be interptreted in different ways. It is of vital importance that adequate definitions for these terms and concepts are provided, because of the area of tension betrween those that control and those being controlled. The creation of a common conceptual framework and the maintenance of concepts and definitions can be supported by the construction of an organization-specific lexicon and the use of modern IT tools.

IT organizations and CEO‟s are, and should be, concerned these days about the (lack of) data confidentiality and the usage of „shadow‟ IT systems by employees. Not only does the company risk monetary loss or public embarrassment, the senior management might also risk personal fines or even imprisonment. Several trends reinforce the attention for these subjects, including the fact that an increasing number of people perform parts of their work tasks from home (RSA, 2007) and the increasing bandwidth available to internet users which makes them rely on the Internet for satisfying their business and personal computing needs (Desisto et al. 2008). Employee compliance with the existing IT security policies is therefore essential. This paper presents a study on factors that influence non-compliance behavior of employees in organizations. The factors found in literature are tested in a survey study amongst employees of a big-four accountancy firm in the Netherlands and Belgium. The study concludes that stricter IT governance and cultural aspects are the most important factors influencing non-compliance behavior.

Preprint submitted to Information Processing & Management Tags are a convenient way to label resources on the web. An interesting question is whether one can determine the semantic meaning of tags in the absence of some predefined formal structure like a thesaurus. Many authors have used the usage data for tags to find their emergent semantics. Here, we argue that the semantics of tags can be captured by comparing the contexts in which tags appear. We give an approach to operationalizing this idea by defining what we call paradigmatic similarity: computing co-occurrence distributions of tags with tags in the same context, and comparing tags using information theoretic similarity measures of these distributions, mostly the Jensen-Shannon divergence. In experiments with three different tagged data collections we study its behavior and compare it to other distance measures. For some tasks, like terminology mapping or clustering, the paradigmatic similarity seems to give better results than similarity measures based on the co-occurrence of the documents or other resources that the tags are associated to. We argue that paradigmatic similarity, is superior to other distance measures, if agreement on topics (as opposed to style, register or language etc.), is the most important criterion, and the main differences between the tagged elements in the data set correspond to different topics

This chapter explores qualitative career assessment as an identity learning process where meaning-oriented learning is essential and distinguished from conditioned or semantic types of learning. In order to construct a career identity in the form of a future-oriented narrative, it is essential that learners are helped through cognitive learning stages with the help of a dialogue about concrete experiences which aims to pay attention to emotions and broadens and deepens what is expressed.

What is a pop-up store and how can it be used for organisational counterspacing? The pop-up can be interpreted as a fashionable and hypermodern platform focusing on the needs of a younger generation of consumers that searches for new experiences and is prone to ad hoc decision-making. From this perspective, the pop-up is a typical expression of the experience economy. But it is more. The ephemeral pop-up store, usually lasting from one day to six months, is also a spatial practice on the boundary between place as something stable/univocal and space as something transitory/polyphonic. Organizational theory has criticized the idea of a stable place and proposed the concept of spacing with a focus on the becoming of space. In this article, the pop-up store is introduced as a fashionable intervention into organizational spacing. It suggests a complementary perspective to non-representational theory and frames the pop-up as co-actor engaging everyday users in appropriating space. Drawing on Lefebvre’s notions of differential space, festival and evental moment, theory is revisited and then operationalized in two pop-up store experiments. Apart from contributing to the ongoing theoretical exploration of the spacing concept, this article aims to inspire differential pop-up practices in organisations. https://www.linkedin.com/in/overdiek12345/

The purpose of the paper is to start a dialogue about differences between Western and Eastern cultures in the way they conceptualize knowledge and discuss the implications of these differences for a global intellectual capital (IC) theory and practice. A systematic metaphor analysis of the concept of knowledge and IC is used to identify common Western conceptualizations of knowledge in IC literature. A review of philosophical and religious literature was done to identify knowledge conceptualizations in the main streams of Asian philosophy. Fundamental differences were found in the way knowledge is conceptualized. In Western IC literature common metaphors for knowledge include knowledge as a thing and knowledge as capital. In Asian thought, knowledge is seen as unfolding truth based upon a unity of universe and human self and of knowledge and action. The research was performed on a limited sample of literature. More research is needed to identify how knowledge is conceptualized in the practice of doing business in Asia and to test the effects of introducing IC theories to Asian businessmen and managers. Moreover, it might be questionable whether different types of resources (Western management literature on IC and Asian cultural philosophies) can be put in a comparative perspective to extract conclusions out of it. This methodological starting point has its confinements, but is plausible partly as long as IC theories originating from an Asian background are still missing, partly as far as philosophical notions within Western IC publications are contrasted with Asian notions of knowledge. Despite this restriction we would like to emphasize that Western conceptualizations of knowledge, embedded in terms like intellectual capital and knowledge management, can not be transferred to Asian business without considering the local view on knowledge. Asian conceptualizations of knowledge should play an important role in the further development of a knowledge-based theory and practice of the firm. We choose deliberately to contrast Western philosophy with cultural and religious connotations in Asian philosophy, as the underlying paradigm is strongly influenced by these notions. This is clearly perceivable in revivalist and reformist tendencies in Buddhism, Hinduism and Islam. Religious notions within these traditions have a strong paradigmatic function in a cognitive and normative sense. Not only in anthropology but also in epistemology, contemporary Asian thought is dominated by a discourse deeply embedded in religious and cultural traditions, in which the dimensions of 'nature', 'subjectivity' and 'history' have well defined boundaries. Anthropologically and epistemologically, all spheres of human reality are analyzed and described within the perspective of an integral and monolithic unity, in which all dimensions and spheres of being are bound. In Western philosophy these spheres of being have been separated from religious notions because of a longstanding secularization due to which religion and culture, metaphysics and philosophy have become separate disciplines.(Boom, 1993)

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.

Many citizens experience ambivalence – having simultaneously positive and negative evaluations – about changing their behaviour towards a more environmentally friendly lifestyle. Based on 36 studies, this study identifies and synthesises the current evidence on how ambivalence impacts environmental behaviours. In most studies, ambivalence is shown to be directly and negatively associated with environmental behaviours, i.e., higher levels of ambivalence are linked to lower levels of environmentally friendly and unfriendly behaviours. This applies to both types of ambivalence: objective (OA) and subjective (SA). Mediator analyses show, in line with the theory, that SA, not OA, drives behavioural change. In addition, results indicate that ambivalence moderates the relationship between independent–dependent variables mainly negatively, for example, by weakening attitude–behaviour relationships. This review shows the potential of ambivalence to facilitate behaviour change: SA about environmentally friendly behaviour can hinder, whereas SA about environmentally unfriendly behaviour can motivate, behaviour change. In addition, this review highlights some significant knowledge gaps in this body of research. A lack of validated standardised measurements of ambivalence makes it challenging to compare studies and reach conclusions about underlying theoretical constructs. Methods, research designs, and theoretical underpinnings need improvement to fully understand ambivalence and progress towards the transition of environmentally friendly behaviours.
