The purpose of this paper is to provide an understanding of process improvement team member perceptions regarding the effectiveness of asynchronous e‐collaboration.

A field‐based, two‐phase canonical action research study was conducted at two different sites. Data were obtained from observations and interviews of all team members. Media synchronicity theory was utilized to hypothesize the interplay of media capabilities, task communication processes, and team functions.

Eight primarily virtual teams solved complex problems and provided feedback on the effectiveness of various communications media. The results support media synchronicity theory.

Media synchronicity theory provides an alternative explanation for studies both supporting and contradicting media richness theory. The teams in this study were newly formed. Further investigation of established teams and other contexts is warranted.

For complex problem‐solving tasks performed by newly formed teams, communications media with low synchronicity (e.g. listserv, e‐mail, bulletin board) may be appropriate for conveyance of information; whereas media with high synchronicity (e.g. face‐to‐face, telephone) may be more desirable for convergence on shared meaning.

As geographic, temporal, and cost constraints move organizations toward virtual team work for increasingly complex tasks, research is warranted on effective utilization of available communication technology for solving business problems without face‐to‐face communication. This research paper examines the issue through an emerging theoretical lens, media synchronicity theory, and suggests a new proposition.

Applying media synchronicity theory (MST) as a theoretical foundation, this paper aims to examine whether teams using multiple communication modes perform better on a complex intra-team task than those using a single mode.

The authors adopted a mixed-methods explanatory design. Data were collected from 44 teams directly following participation in the Everest Leadership and Team Simulation. Teams were assigned a specific mode of communication: virtual (text-chat only), face-to-face (FTF) or dual (FTF and chat).

No significant differences in team goals achieved were found when comparing dual modes to single modes, counter to predictions based on MST. Qualitative data indicated that FTF communication is dominant and might lead to “medium inertia” when multiple modes are available. FTF teams reported higher perceptions of team effectiveness than text-chat-only teams.

This study was conducted on a small number of teams in an artificial environment; therefore, generalizability is limited. Future research should consider other measures of team performance and test teams in a virtual setting where distance, as well as time, are factors.

FTF communication tends to be dominant to a point where virtual options are ignored, suggesting that greater awareness around communication processes required for complex tasks, and ways to appropriate different media for conveyance or convergence, is key to team performance.

This study highlights the importance of determining processes by which teams shift between media to maximize conveyance and convergence processes. Additionally, distinguishing between objective performance and perceptions of performance highlight an additional challenge for teams that can be explored.

This paper aims to explore how big data analytics (BDA) emerging technologies crossed with social media (SM). Twitter can be used to improve decision-making before and during maritime accidents. We propose a conceptual early warning system called community alert and communications system (ComACom) to prevent future accidents.

Based on secondary data, the authors developed a narrative case study of the MV Wakashio maritime disaster. The authors adopted a post-constructionist approach through the use of media richness and synchronicity theory, highlighting wider community voices drawn from social media (SM), particularly Twitter. The authors applied BDA techniques to a dataset of real-time tweets to evaluate the unfolding operational response to the maritime emergency.

The authors reconstituted a narrative of four escalating sub-events and illustrated how critical decisions taken in an organisational and institutional vacuum led to catastrophic consequences. We highlighted the specific roles of three main stakeholders (the ship's organisation, official institutions and the wider community). Our study shows that SM enhanced with BDA, embedded within our ComACom model, can better achieve collective sense-making of emergency accidents.

This study is limited to Twitter data and one case. Our conceptual model needs to be operationalised.

ComACom will improve decision-making to minimise human errors in maritime accidents.

Emergency response will be improved by including the voices of the wider community.

ComACom conceptualises an early warning system using emerging BDA/AI technologies to improve safety in maritime transportation.

This analysis is the first to explore the overall roles of the offsetting attraction and distraction influences of earnings news in shaping the level of attention given to the equity market by market participants.

We use multivariate regression approach and examine how trading activity levels within the set of non-announcing firms varies with respect to collective measures of contemporaneous earnings announcement visibility. We employ attention and information transfer theories in our hypothesis development.

This analysis is the first to explore the overall roles of the offsetting attraction and distraction influences of earnings news in shaping the level of attention given to the equity market by market participants. Specifically, we examine how the number of earnings announcement activity affects investor attention as measured by trading volume given to the set of non-announcing firms. We find that while earnings announcement numbers lower trading volume responses to earnings news among announcing firms (consistent with Hirshleifer et al., 2009), their distractive influence does not carry over into the market as a whole. More importantly, investor attention to both the overall market and the larger subset of non-announcing firms increase in response to earnings news activity levels. However, after decomposing the announcers as same-industry and different-industry announcers, we find that investor attention to the non-announcing segment of the market increases with the number of same-industry announcers, but actually seems to decrease (i.e. they distract attention) with the number of different-industry announcers. We also find that the associated earnings surprise brings attention to non-announcing firms (consistent with earnings news is relevant to overall market price movements). Finally, we find that distraction effects are attenuated in the financial crisis period.

A promising area of future research is to examine the relation between market pricing efficiency and aggregate earnings activity for the set of non-announcing firms. Although it will be a challenging task to measure pricing efficiency for the non-announcers, this will complement the prior literature only focusing on the announcing segment of the market.

First, instead of assessing the impact of number of earnings announcements on the subset of announcing firms, which is a micro-level perspective, we identify the impact of news arrivals on all firms in the market including the vastly larger set of non-announcing firms. Second, by decomposing the number of announcements into industry-related and -unrelated news we show that different types of news arrivals spark investor attention differently, suggesting the importance of categorizing the news into related and unrelated industries.

A potential future area of research identified by our analysis is to investigate what type of investors' attention is distracted or attracted during the earnings announcements. A promising area of future research is to examine the relation between market pricing efficiency and aggregate earnings activity for the set of non-announcing firms.

This paper is the first one exploring the overall roles of the offsetting attraction and distraction influences of earnings announcements in shaping the level of investor attention given to the equity market by market participants. Our findings should be of interest to investors, analysts, security market regulators and researchers.

The miniscule wireless sensor nodes, engaged in the wide range of applications for its capability of monitoring the physical changes around, requires an improved routing strategy with the befitting sensor node arrangement that plays a vital part in ensuring a completeness of the network coverage.

This paves way for the reduced energy consumption, the enhanced network connections and network longevity. The conventional methods and the evolutionary algorithms developed for arranging of the node ended with the less effectiveness and early convergence with the local optimum respectively.

The paper puts forward the befitting arrangement of the sensor nodes, cluster-head selection and the delayless routing using the ant lion (A-L) optimizer to achieve the substantial coverage, connection, the network-longevity and minimized energy consumption.

The further performance analysis of the proposed system is carried out with the simulation using the network simulator-2 and compared with the genetic algorithm and the particle swarm optimization algorithm to substantiate the competence of the proposed routing method using the ant lion optimization.

The purpose of the paper is to examine how media synchronicity facilitates the emergence of social exchange (i.e. trust and reciprocity) in organizations’ information and communication technology (ICT)-mediated interactions. A model of media synchronicity in organizational social exchange (MSiOSE) is proposed.

The paper has a design and review approach. The theoretical analysis is based on social exchange theory (SET) and media synchronicity theory (MST).

The authors propose that, in general, social exchange benefits from both asynchronous and synchronous communication processes. However, media synchronicity has different boundary conditions (i.e. pros and cons) in relation to the emergence of social exchange, determined in accordance with the mutually interacting patterns of trust and reciprocity predicted by SET. The authors provide testable theoretical propositions to support the analysis.

Social exchange is a critical business factor for organizations due to its well-known positive outcomes, such as the strengthening of social ties. The need for successful social exchange in remote work conditions is particularly emphasized. However, with regard to the communication and behavioral patterns that lead to social exchange via ICT, the theoretical understanding is limited. The study reveals previously unmapped heuristics between social exchange and physical media capabilities. Thus, the study's propositions can be used to study and analyze social exchange in the ever-changing media landscape. As a practical contribution, the study helps organizations to improve their communication strategies and use of ICT.

Confirmations are applied in kit preparation for mixed-model assembly to promote quality, but research that explains the impact on time efficiency has been lacking. The purpose of this paper is to determine the extent to which the type of confirmation method relates to time-efficient kit preparation when order batching is applied.

An industrially relevant laboratory experiment is applied, simulating kit preparation with order batching for mixed-model assembly. The time efficiency is studied as associated with four confirmation methods – barcode ring scanner, button presses, voice commands and RFID-reading wristbands – when applied as pick-from and place-to confirmation. Furthermore, the paper also considers the quality outcome.

Efficiency is promoted by methods that minimise interrupting the picker’s motions when performing pick-from confirmations and with methods that allow each hand to place components and perform place-to confirmations simultaneously – here represented by button presses and RFID-reading wristbands. Moreover, combining various methods for the tasks of pick-from or place-to confirmation can benefit efficiency.

Pickers at an early stage of the learning curve (one shift of training) were considered.

The findings promote the customised applications of picking information systems in industry.

Combining various methods for the tasks of pick-from and place-to confirmation can provide more fitting applications that better align with the picker’s preferences.

Combinations of various methods when applied as either pick-from or place-to confirmation, or both, are studied.

This paper describes a research and development effort on a GIS‐based pipeline planning system (GIS‐based PPS). Research was first conducted to identify the aspects of pipeline planning and pipeline network design that could benefit from a computer assisted approach, and the recent advancements in information technology. This paper describes a cohesive computer environment that integrates the hydraulic analysis and geographic information processing with a graphic user interface (GUI), in order to improve the effectiveness of pipeline design functions. An interactive system prototype was implemented and is currently being applied in real‐world pipeline network planning and design for municipal and industrial water conveyance.

This paper is an outcome of the study made for designing the multimedia‐based orientation programme of the Dyal Singh College Library (DSCL), New Delhi, India. The purpose of this paper is to enlighten the new students and to create insight into the operations of the DSCL.

Macromedia Flash software is used in designing and developing the multimedia‐based library orientation programme of the DSCL. In this study, the quality and usefulness of the information provided is evaluated through feedback. The structure of the programme is divided into 227 snapshots lasting for 20 min. A survey was conducted using structured feedback comprising of five questions.

Regarding the implementation of multimedia‐based library orientation programme and the responses received from the respondents regarding usefulness of information presented in the programme, except “library online public access catalogue & internet browsing”, all other features are found to be either excellent or very good. The quality features, such as, easy to understand (76.44 per cent), programme content (60.23 per cent), programme graphics, sound and special effects (46.76 per cent) are rated as excellent; and the length of the programme (72.28 per cent) and comprehensiveness (51.74 per cent) are rated as good. The overall evaluation of the programme is rated as very good (62.55 per cent).

This paper is not conceived to replace live college library tours, but rather to supplement them. In its present non‐linear form, the programme allows the user to start at the beginning and run through to the end. However, users cannot interact with the video but they can stop, forward and backward the programme.

Highly useful for new students who face the constraints of inconvenient timings and format; reduces the burden of the library staff of imparting physical library orientation and improves the library image in this age of information; and helps the user in overcoming the geographical and language barriers.

The paper provides the advantages of multimedia‐based library orientation in college libraries. The multimedia‐based library orientation programme has been developed as an effective means of conveyance and makes information handy and accessible on the college site as “virtual tour”. The entire programme can be viewed at and develops creativity among college librarians in designing such programmes.
