Computational evacuation modelling as a part of approval procedures or design processes is sometimes concerned with vulnerable people requiring special attention. This vulnerability can be based on external circumstances or on individual characteristics. Microscopic methods are well suited to deal with such specific determinants by their ability to model individual movement and certain behavioural aspects. By reference to case studies the possibilities of up-to-date individual evacuation models to cover egress scenarios including vulnerable people are discussed. The selected examples demonstrate that the evacuation of vulnerable people often depends more on the modelling of individual behaviour rather than on a very detailed description of individual characteristics. Group formation and the guidance or assistance of other people will have a strong impact on the evacuation process and thus require special modelling techniques and respective calibration and validation efforts guided by empirical studies.

Adaptive hypermedia learning systems can be developed to adapt to a diversity of individual differences. Many studies have been conducted to design systems to adapt to learners’ individual characteristics, such as learning style and cognitive style to facilitate student learning. However, no research has been done specifically regarding the adaptation of hypermedia learning system to gender differences. This chapter therefore attempts to fill this gap by examining the published findings from experimental studies of interaction between gender differences and hypermedia learning. Analysis of findings of the empirical studies leads to a set of principles being proposed to guide adaptive hypermedia learning system design onthe basis of gender differences in relation to (i) adaptive presentation and (ii) adaptive navigation support.

Purpose – The purpose of this paper is to propose a theoretical model that links the major antecedents, outcomes, and moderators of employee engagement. Design/methodology/approach – This paper uses the first part of Dubin's two-part, eight-step theory-building methodology, and builds on existing research and empirical studies on engagement. In particular, the following five steps of the Dubin's methodology are addressed in this study: units (or concepts) of the theory, laws of interaction among the units, boundaries of the theory, system states of the theory, and propositions of the theory. Findings – The proposed theoretical model of employee engagement identifies job design and characteristics, supervisor and co-worker relationships, workplace environment, and HRD practices as the major antecedents to employee engagement. The paper also proposes that job demands and individual characteristics act as moderators to the relationships between job design and characteristics, supervisor and co-worker relationships, workplace environment, and employee engagement. Finally, it is proposed that employee engagement is related to three major organizational outcomes: job performance, turnover intention (inverse relationship), and organizational citizenship behavior. Originality/value – This paper addresses the paucity of structured literature on the antecedents and outcomes of employee engagement and presents a comprehensive, holistic model that offers a logical ground on which empirical indicators and hypotheses could be further identified and tested to verify the theory.

Native advertising has become an increasingly important revenue component for many online journalism publications. Because Web consumers engage in advertising avoidance strategies when using the Web, advertisers have gradually come to rely increasingly on paid advertising that resembles in format, appearance, and content non-advertising content on websites. On news websites, native advertising forms include sponsored content, sponsored homepage links, and sponsored article-referral links. The spread of native advertising news content has led to concern that news consumers fail to recognize it as advertising, and questions about whether it is unethical or deceptive. Contemporary native advertising is not the first content delivered alongside news that blurs the boundaries between editorial and paid promotional content. Print advertorials, which took root in newspapers and magazines in the mid-20th century, are a direct analogue, but host-read ads on radio and television programs, text-based search engine result advertising, and newspaper special advertising sections can all be seen as advertising content designed to feel like non-paid content. However, because contemporary native advertising takes so many different forms, and because practices of disclosure to the user are so varied, there has been a rise in public concern and academic inquiry into the prevalence and effects of native advertising. Native advertising on online news sites has generated a number of ethical concerns from practitioners, media critics, and consumers. On the production side, scholars and practitioners worry that the creation of content on behalf of, or in partnership with, advertisers may erode norms of editorial independence that have governed media organizations’ practices for over half a century. Others are concerned that as consumers become accustomed to seeing articles produced with advertiser input, the credibility of news organizations and trust in their non-advertising content will decrease. Perhaps most prominent have been concerns that native advertising deliberately disables consumers’ ability to recognize advertising elements on a website, rendering advertiser and publisher liable for deceiving consumers. Research on native advertising has focused primarily on understanding how consumers detect and perceive native advertising, with additional streams focused on descriptive analyses of native advertising content and practitioner perspectives. Empirical studies show that many consumers do not recognize native advertising, and that there are substantial differences in how the content is received and trusted between those who recognize it and those who do not. Scholars have also identified characteristics of content, disclosure practices, and individual characteristics that influence the likelihood of advertising recognition.

Calls in the entrepreneurship literature have advocated theory development and empirical studies exploring fear of failure. Often viewed as an inhibitory factor towards entrepreneurial activity, contemporary research has suggested that fear of failure can also motivate entrepreneurial activity. To explore this issue, we draw on Protection Motivation Theory to conceptualise and operationalise fear of failure. We find support for the notion that fear of failure prompts the adoption of entrepreneurial strategies, provided the entrepreneur believes they have the ability to act entrepreneurially, and that by so doing, their financial situation will improve. Our approach extends the literature on fear of failure in an entrepreneurship context by disentangling cognitive and behavioural aspects focusing not only on threat appraisals, but also on how entrepreneurs cope with them.

Employees' job satisfaction is influenced by a number of diverse determinants which are related with the work performed by an employee, depend on individual characteristics of an employee, and result from the features of the environment in which a given organisation is functioning. Job satisfaction affects the functioning of an enterprise, its competitiveness and profitability, and high level of employees' satisfaction may be a key factor impacting the success of the whole organisation. The aim of the paper is to show which determinants of job satisfaction, and at what level, can be distinguished among employees of Polish enterprises, depending on selected variables. A questionnaire survey conducted in 2015 on a group of 158 enterprises enabled identification of statistical dependences and verification of formulated research hypotheses which defined, among other things: the impact of the determinants of employees' job satisfaction depending on the age of a company, its size, or period of employment of its employees.

Stress aspects still remain as an existing problem, which requires further interdisciplinary studies. Considering the strong impact of chronic exposure to psychosocial stressors at a workplace in relational and incentives contexts of undertaking professional duties, those aspects gain in importance in teachers’ work. A person stays in a continuouscontact with a student, parent or another teacher, and their motivation seems to be a key aspect for the entire education process. The presented article is an attempt to capturestress indicators in a teachers’ work, as well as ways of dealing with them in a school reality. The article begins by highlighting the most important stress definitions, followed by a brief methodology of self-research. Then the author describes stressors present in teacher’s work, which were identified in empirical studies, and ways of dealing with stress used by tested teachers. The article ends with conclusions and recommendations for further representative studies.

Novel design methodologies are often evaluated through empirical studies involving human designers. However, such empirical studies can incur a high personnel cost. Further, it can be difficult to isolate the effects of specific team or individual characteristics. These limitations could be bypassed by employing a computational model of design teams. This work introduces the Cognitively-Inspired Simulated Annealing Teams (CISAT) modeling framework, an agent-based platform that provides a means for efficiently simulating human design teams. A number of empirically demonstrated cognitive phenomena are modeled within the platform, striking a balance between model simplicity and direct applicability to engineering design problems. This paper discusses the composition of the CISAT modeling framework and demonstrates how it can be used to simulate the performance of human design teams in a cognitive study. Results simulated with CISAT are compared directly to the results derived from human designers. Finally, the CISAT model is also used to investigate the characteristics that were most and least helpful to teams during the cognitive study.

Object-oriented (OO) approaches of software development promised better maintainable and reusable systems, but the complexity resulting from its features usually introduce some faults that are difficult to detect or anticipate during software change process. Thus, the earlier they are detected, found and fixed, the lesser the maintenance costs. Several OO metrics have been proposed for assessing the quality of OO design and code and several empirical studies have been undertaken to validate the impact of OO metrics on fault proneness (FP). The question now is which metrics are useful in measuring the FP of OO classes? Consequently, we investigate the existing empirical validation of CK + SLOC metrics based on their state of significance, validation and usefulness. We used systematic literature review (SLR) methodology over a number of relevant article sources, and our results show the existence of 29 relevant empirical studies. Further analysis indicates that coupling, complexity and size measures have strong impact on FP of OO classes. Based on the results, we therefore conclude that these metrics can be used as good predictors for building quality fault models when that could assist in focusing resources on high risk components that are liable to cause system failures, when only CK + SLOC metrics are used.
