Doing a Good Job—the Effect of Primary Task Quality on Well‐Being and Job Satisfaction

This paper investigates whether employees’ assessment of their primary task quality has a significant impact on their well‐being and job satisfaction, respectively. Furthermore, the paper hypothesizes that professional values and norms affect employees’ quality expectations on their work tasks and thus their assessment of primary task quality. The paper proposes a measure for primary task quality and uses it in the analyses of responses from 1,247 preschool teachers and teaching assistants in 94 public daycare centers in Denmark. The results indicate that an important factor for employees is their experience of quality in the job they perform. Moreover, quality expectations can differ between employees performing the same task due to, for example, difference in professional training. This leads us to propose a new research direction for job design theory that addresses employees’ assessment of the quality of their primary task job performance.     

Virtual Support Communities and Psychological Well‐Being: The Role of Optimistic and Pessimistic Social Comparison Strategies

Do the beneficial or detrimental effects of CMC activity depend on the specific social comparison strategy individuals use? The present study aimed to answer this question by examining social comparison strategies, different measures of online activity within the community, and psychological well‐being of users of online breast cancer support communities. Results showed that the relationship between online activity (i.e., length of visits and frequency of posts) and psychological well‐being (i.e., breast cancer related concerns and depression) was determined by users' pessimistic social comparison strategy; downward identification influenced especially highly active users. Findings suggest that active CMC users should be careful not to become entrapped by negative social comparison processes.     

The Relationship Between Facebook Use and Well‐Being Depends on Communication Type and Tie Strength

An extensive literature shows that social relationships influence psychological well‐being, but the underlying mechanisms remain unclear. We test predictions about online interactions and well‐being made by theories of belongingness, relationship maintenance, relational investment, social support, and social comparison. An opt‐in panel study of 1,910 Facebook users linked self‐reported measures of well‐being to counts of respondents' Facebook activities from server logs. Specific uses of the site were associated with improvements in well‐being: Receiving targeted, composed communication from strong ties was associated with improvements in well‐being while viewing friends' wide‐audience broadcasts and receiving one‐click feedback were not. These results suggest that people derive benefits from online communication, as long it comes from people they care about and has been tailored for them.     

Employee Creativity and R&D: A Critical Review

Employee creativity is one of the most important components to measure a company's human capital, particularly in knowledge‐intensive companies. However, the complexity of the conception of creativity means that the measurement of employee creativity has become difficult. Reflecting discussions and contributions on Creativity in R&D as presented at the 2006 R&D Management Conference held in Taiwan, this short thematic paper reviews four different and critical approaches to creativity, namely the evolutionary approach, the cross‐disciplinary science approach, the social system approach and the social network approach. This paper concludes that the four approaches provide complementary contributions in understanding the measurement of creativity in an R&D context, but that the interaction of the socio‐cultural context with employee creativity needs to be taken into account.     

Leader Self‐Reported Emotional Intelligence and Perceived Employee Creativity: An Exploratory Study

This research studies the relationship between six dimensions of leaders' emotional intelligence and two dimensions of employee creativity. A sample of 138 managers from 66 organizations reported on their own emotional intelligence and the creativity of their teams. Our results point out two main findings: (a) leaders' emotional intelligence explains significant variance of both creativity dimensions; (b) emotional intelligence dimensions with higher predictive power are self‐control against criticism and empathy. The findings suggest that emotionally intelligent leaders behave in ways that stimulate the creativity of their teams.     

Predictors of Online Health Information Seeking Among Women with Breast Cancer: The Role of Social Support Perception and Emotional Well‐Being

This study attempts to examine the role of social support perception and emotional well‐being on online information seeking among cancer patients within the context of CHESS, a well‐established Interactive Cancer Communication System (ICCS). Factor and regression analyses conducted among 231 breast cancer patients revealed that social support perception and emotional well‐being interacted with each other to influence online health information seeking. Patients with low social support perception and high emotional well‐being were most likely to seek health information, whereas patients with high social support perception and high emotional well‐being sought out the same information least. Practical implications of the study findings are further discussed.     

Multimodal Connectedness and Quality of Life: Examining the Influences of Technology Adoption and Interpersonal Communication on Well‐Being Across the Life Span

This study examined the relationship between the number of communication technologies used for social interactions (i.e., multimodal connectedness) and well‐being across the lifespan. Consistent with the assumptions of media multiplexity, multimodal connectedness and frequency of strong‐tie communication enhanced well‐being, but only for older‐age cohorts (35–54 and 55–70+). For young adults (18–34), multimodal connectedness and frequency of weak‐tie communication diminished well‐being. The findings are framed in terms of differing motives for maintaining social relations across the lifespan, as maintenance of relationships with strong ties become more important and the number of weak ties contract as people age.     

UK Film Companies: Project‐Based Organizations Lacking Entrepreneurship and Innovativeness?

The growth of project‐based forms of organization has been interpreted as a response to rapidly changing technological and market environments. Companies operating in this way are assumed to be inherently innovative, continually breaking up and reconfiguring teams of workers whose highly developed skills enable them to multi‐task and apply their knowledge in novel situations, in which new technology is swiftly assimilated and deployed. Project workers, who may engage in repeat contracting with different employers, belong to technical communities wherein knowledge is developed and resides. The transformation from vertical integration to project‐based working in the film industry would thus appear to privilege innovation. However, in the UK film industry at least, this study suggests that, in spite of freelance working, crew and technicians follow highly specialized, hierarchical careers, and that the organization of production is virtually the same as it was at the height of the Hollywood ‘Studio System’. Furthermore, it will be argued that the informal, reputational networks that operate in the UK industry may act as a barrier to development rather than as an engine of change.     

Image‐to‐Geometry Registration: a Mutual Information Method exploiting Illumination‐related Geometric Properties

This work concerns a novel study in the field of image‐to‐geometry registration. Our approach takes inspiration from medical imaging, in particular from multi‐modal image registration. Most of the algorithms developed in this domain, where the images to register come from different sensors (CT, X‐ray, PET), are based on Mutual Information, a statistical measure of non‐linear correlation between two data sources. The main idea is to use mutual information as a similarity measure between the image to be registered and renderings of the model geometry, in order to drive the registration in an iterative optimization framework. We demonstrate that some illumination‐related geometric properties, such as surface normals, ambient occlusion and reflection directions can be used for this purpose. After a comprehensive analysis of such properties we propose a way to combine these sources of information in order to improve the performance of our automatic registration algorithm. The proposed approach can robustly cover a wide range of real cases and can be easily extended.     

Folksonomy‐Based Recommender Systems: A State‐of‐the‐Art Review

Collaborative tagging systems, also known as folksonomies, have grown in popularity over the Web on account of their simplicity to organize several types of content (e.g., Web pages, pictures, and video) using open‐ended tags. The rapid adoption of these systems has led to an increasing amount of users providing information about themselves and, at the same time, a growing and rich corpus of social knowledge that can be exploited by recommendation technologies. In this context, tripartite relationships between users, resources, and tags contained in folksonomies set new challenges for knowledge discovery approaches to be applied for the purposes of assisting users through recommendation systems. This review aims at providing a comprehensive overview of the literature in the field of folksonomy‐based recommender systems. Current recommendation approaches stemming from fields such as user modeling, collaborative filtering, content, and link‐analysis are reviewed and discussed to provide a starting point for researchers in the field as well as explore future research lines.     

Multiple‐Robot Simultaneous Localization and Mapping: A Review

Simultaneous localization and mapping (SLAM) in unknown GPS‐denied environments is a major challenge for researchers in the field of mobile robotics. Many solutions for single‐robot SLAM exist; however, moving to a platform of multiple robots adds many challenges to the existing problems. This paper reviews state‐of‐the‐art multiple‐robot systems, with a major focus on multiple‐robot SLAM. Various issues and problems in multiple‐robot SLAM are introduced, current solutions for these problems are reviewed, and their advantages and disadvantages are discussed.     

Ontology‐Based Representation and Modelling of Synthetic 3D Content: A State‐of‐the‐Art Review

An indispensable element of any practical 3D/VR/AR application is synthetic three‐dimensional (3D) content. Such content is characterized by a variety of features—geometry, structure, space, appearance, animation and behaviour—which makes the modelling of 3D content a much more complex, difficult and time‐consuming task than in the case of other types of content. One of the promising research directions aiming at simplification of modelling 3D content is the use of the semantic web approach. The formalism provided by semantic web techniques enables declarative knowledge‐based modelling of content based on ontologies. Such modelling can be conducted at different levels of abstraction, possibly domain‐specific, with inherent separation of concerns. The use of semantic web ontologies enables content representation independent of particular presentation platforms and facilitates indexing, searching and analysing content, thus contributing to increased content re‐usability. A range of approaches have been proposed to permit semantic representation and modelling of synthetic 3D content. These approaches differ in the methodologies and technologies used as well as their scope and application domains. This paper provides a review of the current state of the art in representation and modelling of 3D content based on semantic web ontologies, together with a classification, characterization and discussion of the particular approaches.     

Interactive Character Animation Using Simulated Physics: A State‐of‐the‐Art Review

Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as fluids, cloths and rag‐doll characters, commercial applications still resort to kinematics‐based approaches for the animation of actively controlled characters. However, following a renewed interest in the use of physics simulation for interactive character animation, many recent publications demonstrate tremendous improvements in robustness, visual quality and usability. We present a structured review of over two decades of research on physics‐based character animation, as well as point out various open research areas and possible future directions.     

Harvesting Robots for High‐value Crops: State‐of‐the‐art Review and Challenges Ahead

This review article analyzes state‐of‐the‐art and future perspectives for harvesting robots in high‐value crops. The objectives were to characterize the crop environment relevant for robotic harvesting, to perform a literature review on the state‐of‐the‐art of harvesting robots using quantitative measures, and to reflect on the crop environment and literature review to formulate challenges and directions for future research and development. Harvesting robots were reviewed regarding the crop harvested in a production environment, performance indicators, design process techniques used, hardware design decisions, and algorithm characteristics. On average, localization success was 85%, detachment success was 75%, harvest success was 66%, fruit damage was 5%, peduncle damage was 45%, and cycle time was 33 s. A kiwi harvesting robot achieved the shortest cycle time of 1 s. Moreover, the performance of harvesting robots did not improve in the past three decades, and none of these 50 robots was commercialized. Four future challenges with R&D directions were identified to realize a positive trend in performance and to successfully implement harvesting robots in practice: (1) simplifying the task, (2) enhancing the robot, (3) defining requirements and measuring performance, and (4) considering additional requirements for successful implementation. This review article may provide new directions for future automation projects in high‐value crops.     

Organizing for the Big One: A Review of Case Studies and a Research Agenda for Multi‐Agency Disaster Response

Disaster response operations require the cooperation of agencies that seldom interact in their daily operations. The result is a complex coordination problem, which has been in the focus of many case studies. In an effort to facilitate cross‐case learning, this study presents a review of empirical studies on the multi‐agency coordination of disaster response operations. The review covers 80 empirical studies and highlights the importance of training, expertise, planning and plan enactment, leadership and personal acquaintance between the actors in emergent multi‐agency response networks. The analysis results also show that while some areas have received extensive coverage in scholarly publications (e.g., training, skills), a number of important topics have yet to be studied in sufficient depth (e.g., leadership and role taking, plan enactment). Based on these insights, a research agenda is proposed and a number of recommendations for practical disaster response management are made.     

An introduction to PSS‐LCDs: A fast‐optical‐response smectic LCD

Abstract— A new type of fast‐optical‐response liquid‐crystal display is introduced. This display uses a certain type of smectic liquid‐crystal material that has a fast optical response as well as a native wide viewing angle. Unlike well‐known smectic‐based LCD technologies, this new type of LCD technology is highly compatibile with most nematic‐based LCDs. This compatibility provides advantages for practical uses. Here, the initial molecular alignment and drive concept as well as the general performance of this new display technology are discussed.

By marrying literature and examples of social media use with best practices in risk and crisis communication, this study demonstrates how communicators can embrace social media tools to better manage a risk or crisis. Best practices in risk and crisis communication are summarized, examples of social media tools used to manage risks and crises are expounded, and recommendations for practitioners are provided to incorporate social media tools in risk and crisis communication.     

Review: Kd‐tree Traversal Algorithms for Ray Tracing

In this paper we review the traversal algorithms for kd‐trees for ray tracing. Ordinary traversal algorithms such as sequential, recursive, and those with neighbour‐links have different limitations, which led to several new developments within the last decade. We describe algorithms exploiting ray coherence and algorithms designed with specific hardware architecture limitations such as memory latency and consumption in mind. We also discuss the robustness of traversal algorithms as one issue that has been neglected in previous research.     

Organizational Output Innovativeness: A Theoretical Exploration,Illustrated by a Case of a Popular Music Festival

Different interpretations of innovation and innovativeness lead to different approaches and different methods to measure organizational output innovativeness. Two indicators of innovativeness are derived from two divergent approaches: the Referent Innovativeness Index and the Classification Innovativeness Index. The article uses the case of the popular music festival to discuss how these indexes can be operationalized and calculated, as well as to outline the implications of the differences between the methods.
