Abstract:

The employment of smartphone sensors for navigation applications and situational awareness on naval ships and in battlefield applications has been demonstrated. The PASSION application uses Wi-Fi, accelerometers, gyroscopes, QR codes, and manual entry on Android and iPhone tracking applications for ships. This paper primarily discusses supplementing the existing implementation with a new augmentation using Bluetooth Low Energy (BTLE version 4.0). The characteristics of BTLE segregated ranging using Received Signal Strength measurements are explored. The sensitivity of BTLE RSS measurements to environmental factors such as placement, cases, orientation of the device, orientation of the Smartphone and intervening materials is quantified. Algorithms that employ BTLE measurements within the framework of the overall navigation positioning and tracking problem are discussed. Their possible utilization for situational awareness and collaborative navigation is discussed.

Abstract:

Applications to derive maritime value added products like oil spill and ship detection based on remote sensing SAR image data are being developed and integrated at the Ground Station Neustrelitz, part of the German Remote Sensing Data Center. Products of meteo-marine parameters like wind and wave will complement the product portfolio. Research and development aim at the implementation of highly automated services for operational use. SAR images are being used because of the possibility to provide maritime products with high spatial resolution over wide swaths and under all weather conditions. In combination with other information like Automatic Identification System (AIS) data fusion products are available to support the Maritime Situational Awareness.

Abstract:

We tested the effect of leader-follower matches of 182 supervisor and subordinate dyads on organizational citizenship behavior (OCB) in a Chinese context, based on situational leadership theory (SLT). Our aim was to expand the understanding of SLT application in an emerging market in a culture different from Western countries. Results indicated that situational leadership and employee readiness matches had a positive effect on OCB. However, 1 match in which the leader had a coaching role and the employee required detailed directions, was a partial match and was not significantly related to OCB. Theoretical and practical applications are discussed.

Abstract:

Lack of shared understanding among stakeholders is a commonly cited drawback in enterprise architecture development. Stakeholders need to have shared understanding of requirements and principles for an enterprise architecture, and the extent to which the resultant architecture addresses their concerns. However, existing approaches for enterprise architecture development lack adequate capabilities for managing aspects associated with creating shared understanding among stakeholders. Although such aspects can be largely managed by approaches for collaborative decision making and soft systems thinking, these approaches lack details on the enterprise architecture process and its products. Therefore, this paper explores ways of mutually diminishing these gaps through adopting situational method engineering, to guide the development of a situational method for enabling stakeholders to acquire shared understanding of requirements for an enterprise architecture. The situational method presented herein is a component of a broader method for supporting collaboration between stakeholders and architects during enterprise architecture creation. Although the latter was successfully evaluated in 6 enterprises, it exhibited highest performance scores in two enterprises after it was amended with the situational method. Therefore, this paper also presents key findings from evaluating the situational method in the two agencies that are located in Uganda.

Abstract:

Findings from two studies on the design of digital badges for a middle school geometry game and their impact on motivational and cognitive learning outcomes are reported. Study 1 compared the effect of badges in the game to a group with no badges. Badges did not increase posttest performance for all. Learners with high situational interest performed better with badges, learners with low situational interest performed worse with badges. Study 2 compared mastery goal orientation badges with performance goal orientation badges. The interaction of condition and situational interest from Study 1 was replicated. Furthermore, students receiving performance badges performed better on the posttest than students in the mastery badges condition; the no-badges condition was not different from either of the other conditions. Results suggest badges do not always help in educational video games: Types of badges interact with students' interest and motivation to affect learning outcomes.

Abstract:

Purpose The purpose of this paper is to investigate users’ continuous adoption behaviors on mobile game playing from the perspective of situational habit formation. Design/methodology/approach Based on the literature research, a continuous adoption model for situational mobile game is proposed. And the research model is assessed based on data gathered from a sample of 226 mobile game players by employing the structural equation model methodology. Findings The results show that situational cues represented by availability, perceived ease of use and diversion lead to repeated performance that can be represented by flow experience and satisfaction in the situational mobile game playing context. But only flow experience and diversion influence continuous usage directly. Additionally diversion, as a critical situational variable, not only indirectly affects continuous usage intention through flow experience, but also directly affects continuous usage intention for situational mobile game playing. Originality/value Mobile game adoption has been studied from different perspectives, but most research is based on the technology acceptance model. They could not explain the common fact that young people tend to be highly motivated by mobile games and can be regarded as pro-active mobile game players, but many people play mobile games only when they are bored and need a diversion. So this study attempts to illustrate the phenomena to fill the gaps.

Abstract:

This paper explores elaborations of Grounded Theory in relation to Arenas/Social Worlds Theory. The notions of arenas and social worlds were present in early applications of Grounded Theory but have not been as much used or recognised as the general Grounded Theory approach, particularly in the information studies field. The studies discussed here are therefore very unusual in information research. The empirical contexts of these studies are those of (1) the role of discourse in the organisational adaptation in information systems, (2) discourses on Organizational Interoperability in eGovernment and (3) situational analysis and discourses on coping with long term illness. Despite having a common focus on discourse and combining Grounded Theory with the Arenas/Social Worlds Theory, these three studies represent different elaborations of Grounded Theory. The structure of the analytical processes adopted range from a looser application of the constant comparative method to a much more structured analytical approach informed by Situational Analysis. The theoretical implications of the studies are explored. It is concluded that the Arenas/Social Worlds theoretical approach and the use of discourse and situational analysis are particularly appropriate for library and information research and provide a flexible and adaptable research approach for explaining and mapping complex and dynamic domains.

Abstract:

While most researchers do agree now that situations may have an effect in the assessment of traits, the consequences have been neglected, so far: if situations affect the assessment of traits we have to take this fact into account in studies on reliability and validity of measurement instruments and their application. In the theoretical part of this article we provide a more formal exposition of this point, introducing the basic concepts of latent state–trait (LST) theory. LST theory and the associated models allow for the estimation of the situational impact on trait measures in non‐experimental, correlational studies. In the empirical part, LST theory is applied to three well known trait questionnaires: the Freiburg Personality Inventory, the NEO Five‐Factor Inventory and the Eysenck Personality Inventory. It is shown that significant proportions of the variances of the scales of these questionnaires are due to situational effects. The following consequences of this finding are discussed, (i) Instead of the reliability coefficient, the proportion of variance due to the latent trait, the consistency coefficient, should be used for the estimation of confidence intervals for trait scores, (ii) To reduce the situational effects on trait estimates it may be useful to base such an estimate on several occasions, i.e., to aggregate data across occasions. (iii) Reliability and validity studies should not only be based on a sample of persons representative of those to whom the test will be applied; they should also be conducted in situational contexts representative of the intended applications.

Abstract:

Micro blogging sites have become important forums for discussion during disaster events in which Twitter has become one of the important source of real time information. Millions of tweets are posted during disasters, which include not only information about the present situation or relief efforts, but also the emotions or opinion of the masses. Much research has been conducted on extracting situational information from tweets during disaster. However, according to current knowledge, there has not been any prior attempt to study the non-situational tweets posted during disasters, such as those which express the emotions/opinions of the people, political and governmental views, raising charities and event analysis. In this study, the authors characterized the non-situational tweets posted during recent disaster events, the Nepal Earthquake and the Gurudaspur Terrorist attack. They developed a classifier to categorize various types of non-situational tweets into a set of fine-grained classes utilizing state-of-the-art machine learning technique. This system also helps in filtering out communal tweets which can make worst the situation by disrupting communal harmony during certain disaster events.

Abstract:

Extending interactionist principles and targeting situational specificity of trait–performance linkages, trait activation theory (TAT) posits personality traits are expressed as valued work behavior in response to trait-relevant situational cues, subject to constraints and other factors, all operating at the task, social, and organizational levels. Review of 99 key sources citing TAT spanning 2011–2019 reveals diverse applications (e.g., bidirectionality, trait specificity, team building) and an overall 60% significance rate for 262 TAT-based moderator effects reported in 60 of 75 empirical studies. Applying five key aspects of TAT (e.g., behavior/performance distinction, need-based motivation) to five lines of personality dynamics research (e.g., personality states, self-regulation models of motivation) supports TAT as a vehicle for advancing understanding of within-person variability over brief and extended timelines. Critical research needs include personality-oriented work analysis, longitudinal study of trait-situation processes, trait activation in teams, within-job bidirectionality, and situation relevance as a unifying principle in advancing person–workplace fit.

Abstract:

Purpose With the proliferation of virtual reality (VR) applications in electronic commerce, investigations on the effects of VR on consumer responses are important. The purpose of this paper is to examine the effects of online presentation modes (i.e. situational VR, pure VR and picture) on consumer responses for three product types (i.e. geometric, material and mechanical). Design/methodology/approach This study conducted a 3×3 between-subjects experiment to validate the research model and hypotheses. Findings The results revealed that both the situational VR mode and the pure VR mode had a greater impact on product knowledge and purchase intention than the picture mode. The situational VR mode yielded a higher level of product knowledge and purchase intention than the pure VR mode although it was not statistically significant. Furthermore, the pattern of VR modes superiority was found to be consistent across geometric, material and mechanical product types. Originality/value This research study contributes to the VR literature by investigating a new type of VR: situational VR, and offering a more comprehensive picture of consumer responses to online product presentations. The authors then drew the implications from the findings to suggest guidelines for practitioners to efficiently allocate resources and maximize the effectiveness of online presentation modes.

Abstract:

Background. During the last decades, the use of simulations for training purposes has sparked wide interest. However, it is unclear how training format characteristics may affect learning, resulting in a lack of evidence-based guidelines for training developers and organizations. Aim. We explore to what extent variation in the situations presented during a simulation training may improve learning outcomes. We test this research question in the context of a simulation-based training for improving innovation knowledge. Methods. A sample of 131 business students was invited to participate in a study with a pretest and two posttests (within 48 hours after and 4 weeks later) and three conditions: a control group without training, an experimental training group with low situational variation, and an experimental training group with high situational variation. Results and Conclusion. Compared to the control group, high but not low situational variation improved innovation knowledge. Participants’ prior innovation knowledge did not moderate the results. Hence, our findings indicate that ideally a simulation training includes multiple situations that offer learners various opportunities to practice innovation challenges.

Abstract:

This article presents a case study that demonstrates the applicability of unmanned aerial vehicle (UAV) photogrammetric data to land surface deformation monitoring in areas affected by underground mining. The results presented include data from two objects located in the Upper Silesian Coal Basin in Poland. The limits of coordinate and displacement accuracy are determined by comparing UAV-derived photogrammetric products to reference data. Vertical displacements are determined based on differences between digital surface models created using UAV imagery from several measurement series. Interpretation problems related to vegetation growth on the terrain surface that significantly affect vertical displacement error are pointed out. Horizontal displacements are determined based on points of observation lines established in the field for monitoring purposes, as well as based on scattered situational details. The use of this type of processing is limited by the need for unambiguous situational details with clear contours. Such details are easy to find in urbanized areas but difficult to find in fields and meadows. In addition, various types of discontinuous deformations are detected and their development over time is presented. The results are compared to forecasted land deformations. As a result of the data processing, it has been estimated that the accuracy of the determination of XY coordinates and the horizontal displacements (RMS) in best case scenario is on the level of 1.5–2 GSD, and about 2–3 GSD for heights and subsidence.

Abstract:

Abstract The accurate and timely depiction of the state of the atmosphere on multiple scales is critical to enhance forecaster situational awareness and to initialize very short-range numerical forecasts in support of nowcasting activities. The Local Analysis and Prediction System (LAPS) of the Earth System Research Laboratory (ESRL)/Global Systems Division (GSD) is a numerical data assimilation and forecast system designed to serve such very finescale applications. LAPS is used operationally by more than 20 national and international agencies, including the NWS, where it has been operational in the Advanced Weather Interactive Processing System (AWIPS) since 1995. Using computationally efficient and scientifically advanced methods such as a multigrid technique that adds observational information on progressively finer scales in successive iterations, GSD recently introduced a new, variational version of LAPS (vLAPS). Surface and 3D analyses generated by vLAPS were tested in the Hazardous Weather Testbed (HWT) to gauge their utility in both situational awareness and nowcasting applications. On a number of occasions, forecasters found that the vLAPS analyses and ensuing very short-range forecasts provided useful guidance for the development of severe weather events, including tornadic storms, while in some other cases the guidance was less sufficient.

Abstract:

The development, deployment, and maintenance of the current space situational awareness (SSA) information system have become increasingly complex. However, researchers cannot flexibly and conveniently apply the research results to practical applications due to the lack of basic research platforms for SSA. Inspired by X as a Service (XaaS), we propose the microservice-based platform for SSA data analytics to provide a scaffold-like platform for researchers. Based on microservice, the architecture for this platform is proposed to meet the requirements of flexible development and loosely coupled deployment. To facilitate the use of the platform, the hybrid data service layer is established to provide basic data for research and the functional service layer is designed to provide services for clients and applications. Due to the massive data processing requirements, the data analysis architecture and processing model, which can easily integrate various user-defined algorithms and significantly improve the computational efficiency, are proposed based on the Lambda architecture. To verify the platform’s effectiveness, two cases are established and implemented. The results show that this platform can provide a convenient, flexible, and efficient platform for the requirements of algorithm integration, experiment, and data display from users and researchers.

Abstract:

PurposeThe purpose of this research is to explore the ways of integrating situational awareness into business process management for the purpose of realising hyper automated business processes. Such business processes will help improve their customer experiences, enhance the reliability of service delivery and lower the operational cost for a more competitive and sustainable business.Design/methodology/approachOntology has been deployed to establish the context modelling method, and the event handling mechanisms are developed on the basis of event calculus. An approach on performance of the proposed approach has been evaluation by checking the cost savings from the simulation of a large number of business processes.FindingsIn this research, the authors have formalised the context presentation for a business process with a focus on rules and entities to support context perception; proposed a system architecture to illustrate the structure and constitution of a supporting system for intelligent and situation aware business process management; developed real-time event elicitation and interpretation mechanisms to operationalise the perception of contextual dynamics and real-time responses; and evaluated the applicability of the proposed approaches and the performance improvement to business processes.Originality/valueThis paper presents a framework covering process context modelling, system architecture and real-time event handling mechanisms to support situational awareness of business processes. The reported research is based on our previous work on radio frequency identification-enabled applications and context-aware business process management with substantial extension to process context modelling and process simulation.

Abstract:

Enhancing situational awareness in real-time (RT) civil protection and emergency response scenarios requires the development of comprehensive monitoring concepts combining classical remote sensing disciplines with geospatial information science. In the VABENE++ project of the German Aerospace Center (DLR) monitoring tools are being developed by which innovative data acquisition approaches are combined with information extraction as well as the generation and dissemination of information products to a specific user. DLR’s 3K and 4k camera system which allow for a RT acquisition and pre-processing of high resolution aerial imagery are applied in two application examples conducted with end users: a civil protection exercise with humanitarian relief organisations and a large open-air music festival in cooperation with a festival organising company. This study discusses how airborne remote sensing can significantly contribute to both, situational assessment and awareness, focussing on the downstream processes required for extracting information from imagery and for visualising and disseminating imagery in combination with other geospatial information. Valuable user feedback and impetus for further developments has been obtained from both applications, referring to innovations in thematic image analysis (supporting festival site management) and product dissemination (editable web services). Thus, this study emphasises the important role of user involvement in application-related research, i.e. by aligning it closer to user’s requirements.

Abstract:

A helmet-mounted display (HMD)-based computer navigation system that partially mimics the U.S. Army's Land Warrior ensemble provided position information and map updates to soldiers navigating a three-kilometer course. Performance with the HMD system was compared to traditional navigation with paper map, compass, and a hand-held GPS receiver. New objective computer-based measures of navigational accuracy and situational awareness (SA) were developed. Traditional measures of navigational accuracy were not sensitive enough to detect differences between HMD and traditional navigational methods. The more sensitive new measure based on distance traveled found the HMD-based system to be superior. This method is easily adaptable to civilian applications such as orienteering. A supposed advantage of using HMDs is enhanced SA. A SA measure was developed which used probe questions generated by the computer. Although the probe questions found no significant differences between the conditions, the method seems promising for future applications.

Abstract:

During the recent pandemic of COVID-19, an increasing amount of information has been propagated on social media. This situational information is valuable for public authorities. Therefore, this study characterized the propagation scale of situational information types by harnessing the power of natural language processing techniques and machine learning algorithms. We observed that the length of the post has a positive correlation with type 1 information (announcements), and negative words were mostly used in type 5 information (criticizing the government), whereas anxiety-related words have a negative effect on the amount of retweeted type 0 (precautions) and type 2 (donations) information. This type of research study not only contributes to the situational information literature by comprehensively defining categories but also provides data-oriented practical insights into information so that management authorities can formulate response strategies after the pandemic. Our approach is one of its kind and combines Twitter content features, user features and LIWC linguistic features with machine learning algorithms to analyze the propagation scale of situational information, and it achieved 77% accuracy with SVM while classifying the information categories.

Abstract:

The world has been undergoing tremendous transformation since early 2020 with the occurrence of a global pandemic of COVID-19. While it will take several years of study and research to understand the true effect of this pandemic on society, it is worthy of noting that it has already transformed our methods of leading lives. One of the areas, highly impacted by a pandemic is education. In order to deliver education in a distance learning manner, more and more academic institutions have been acquiring IT systems to deliver education to the students in the confines and safety of their homes. Saudi Electronic University (SEU) has been pioneering the application of online systems for blended learning in not just Saudi Arabia but the whole middle east and north Africa region. The reliance on systems at SEU for maintaining education standards during pandemics has increased. This has provided the opportunity to researchers in various fields of IT and computing to study evolving role of such systems in traditional and blended models of education. Situational Factors (SFs) are key elements that affect the acceptability of systems by stakeholders. This paper describes the outcome of the study that was carried out to identify critical Situational Factors that play a major role in the acceptance or otherwise of systems in the academic sphere during pandemic times. The results have shown that knowledge, communication, and trust are the most important situational factors for blended learning applications. The case studies and findings are presented followed by a brief analysis of results.

Abstract:

This paper presents a sensor-orientated approach to on-orbit position uncertainty generation and quantification for both ground-based and space-based surveillance applications. A mathematical framework based on the least squares formulation is developed to exploit real-time navigation measurements and tracking observables to provide a sound methodology that supports separation assurance and collision avoidance among Resident Space Objects (RSO). In line with the envisioned Space Situational Awareness (SSA) evolutions, the method aims to represent the navigation and tracking errors in the form of an uncertainty volume that accurately depicts the size, shape, and orientation. Simulation case studies are then conducted to verify under which sensors performance the method meets Gaussian assumptions, with a greater view to the implications that uncertainty has on the cyber-physical architecture evolutions and Cognitive Human-Machine Systems required for Space Situational Awareness and the development of a comprehensive Space Traffic Management framework.

Abstract:

In today’s increasingly severe network security situation, network security situational awareness provides a more comprehensive and feasible new idea for the inadequacy of various single solutions and is currently a research hotspot in the field of network security. At present, there are still gaps or room for improvement in network security situational awareness in terms of model scheme improvement, comprehensive and integrated consideration, algorithm design optimization, etc. A lot of scientific research investments and results are still needed to improve the form of network security in a long and solid way. In this paper, we propose a network security posture assessment model based on time-varying evidence theory for the existing multisource information fusion technology that lacks consideration of the problem of threat occurrence support rate over time and make the threat information reflect the law of time change by introducing a time parameter in the basic probability assignment value. Thus, the existing hierarchical threat posture quantitative assessment technique is improved and a hierarchical multisource network security threat posture assessment model based on time-varying evidence theory is proposed. Finally, the superiority of the proposed model is verified through experiments.
