Abstract

Purpose

This study aims to improve disaster management. Social media, particularly microblog, has become a new platform for public opinion dissemination. However, few studies have been conducted to explore the structure of public opinions, the approaches for facilitating the spread of public opinions and the results of public opinion dissemination in the context of mobile internet for the purpose of improving disaster management.

Design/methodology/approach

This paper chooses Ebola as the research topic and extracts 14,735 Ebola-related data items from Sina Microblogs to examine the information nodes of public opinion and the characteristics of propagation paths on mobile internet. Particularly, nodes of public opinion between mobile terminals and non-mobile terminals are compared.

Findings

The results of this paper reveal the characteristics of public opinion propagation on mobile internet and verify the effectiveness of public opinion propagation on mobile internet. This study shows that public opinions propagate quickly, widely and efficiently and further generate great impacts on mobile internet.

Research limitations/implications

The methods used in this study can be useful for the government agencies and other relevant organizations to monitor public opinions, identify issues and problems proactively and develop strategies in a more efficient manner to improve disaster management.

Practical implications

The results of this paper are helpful for related departments to monitor public opinions and to further improve disaster management.

Originality/value

This paper explores the mechanism of public opinion dissemination on mobile internet and further investigates how to improve disaster management through a case study related to Ebola.

Abstract

Purpose

The purpose of this paper is to present the integration of logistic management with information and communication technologies to largely improve the effectiveness of logistic fleet operations. The work presented here shows a real‐world fleet management system that integrates mobile communication and supports real‐time logistic information flow management.

Design/methodology/approach

First, the application of information and mobile communication technologies in providing effective logistic distribution service is introduced. Then, the proposed real‐time fleet management system (RTFMS) architecture is depicted, the technology profiles for mobile data terminal (MDT) and logistic information system are described, and the considerations of various wireless mobile communication technologies for logistic distribution process are also addressed. Finally, the implications of this paper are discussed and plans for further work are outlined.

Findings

The proposed architecture for a real‐world logistic fleet management system, the RTFMS, can be served as reference architecture for real‐time logistic fleet management design. The major components of the RTFMS have been described in UML use cases to facilitate reuse of this design. This paper presents the RTFMS architecture with associated information flows and timing considerations could be used for the architecture adaptation in similar applications. Wireless technologies provide the logistics feet management with bi‐directional real‐time information flows as shown in this paper, and this would stimulate new ideas in logistics management and services models.

Research limitations/implications

This paper provides a reference model with implementation in adopting wireless technologies in logistics distribution process. However, the services provided by each specific system would depend on all stakeholders in specific chain of logistics service provider and consumer.

Originality/value

The work presented here shows a real‐world fleet management system that integrates mobile communication and supports real‐time logistic information flow management.

Abstract

Purpose

Vehicle crashes and being struck by vehicles are the leading causes of death among police. The purpose of this paper is to identify risk factors for injury in police officer vehicle crashes in order to help determine the most effective approaches to improve officer vehicle safety.

Design/methodology/approach

The study entailed a cross-sectional survey of officer drivers involved in vehicle crashes from 16 local, county, and state law enforcement agencies across the USA over one year. The relative risk of injury for officers in crashes with a given characteristic relative comparison crashes without that characteristic was computed to determine which characteristics are more likely to be associated with injuries.

Findings

The survey yielded 854 crashes, 90 of which involved injuries to the officer driver. Crash characteristics associated with a statistically significant increase in the risk of injury include multiple vehicle collisions, collision direction, officer vehicle type, officer vehicle being stopped, driving under emergency conditions, conducting traffic control or assisting motorists, not wearing a seat belt, and others. Most findings hold for all crashes and when minor crashes are excluded from the analysis.

Originality/value

This study presents the first quantitative estimates of the risk factors for injury to law enforcement officers in vehicle crashes. Our findings indicate that seat belt use remains a critical safety intervention; driving under emergency conditions is high risk, though the reasons for this are unclear; better practices are needed to protect officers in stationary vehicles; agencies should carefully weigh the benefit of motorcycles against the vastly increased risk of injury they present; and that mobile data terminals are both a major distraction hazard and important source of injuries in crashes.

Abstract

Purpose

The purpose of this paper is to introduce a participatory library service based on artificial intelligence (AI).

Design/methodology/approach

AI technologies and various technologies for facilitating the use of the currently existing libraries and the third-party resources are combined in the new mobile and social networking environments to provide an innovative real-time virtual reference service. Special aesthetic design and library marketing measures are adopted to expand the gains of the service. Questionnaire survey, in-depth interview, and statistical analysis are conducted to evaluate the effects of the service.

Findings

A smart talking robot called Xiaotu (female) is developed. This robot is regarded as a promising new online reference service modus operandi. Four factors contribute to the success of the robot, namely, AI, self-learning, vivid logo and language, and modular architecture.

Practical implications

Xiaotu presents a participatory library service, in which users participate in the resources collection and become content co-creators. Her presence at anytime and anywhere on any kind of terminal maximizes her potential for the delivery of virtual reference services. Xiaotu has the potential to be a general reference robot or a costumed institute robot.

Originality/value

AI is adopted in libraries to form an innovative online reference service. The participatory library service is practiced through a high-featured interactive communication. The aesthetic design of Xiaotu and the related promotions are new in libraries as well.

Abstract

Purpose

This paper aims to propose an extensible, service-oriented framework for context-aware data acquisition, description, interpretation and reasoning, which facilitates the development of mobile applications that provide a context-awareness service.

Design/methodology/approach

First, the authors propose the context data reasoning framework (CDRFM) for generating service-oriented contextual information. Then they used this framework to composite mobile sensor data into low-level contextual information. Finally, the authors exploited some high-level contextual information that can be inferred from the formatted low-level contextual information using particular inference rules.

Findings

The authors take “user behavior patterns” as an exemplary context information generation schema in their experimental study. The results reveal that the optimization of service can be guided by the implicit, high-level context information inside user behavior logs. They also prove the validity of the authors’ framework.

Research limitations/implications

Further research will add more variety of sensor data. Furthermore, to validate the effectiveness of our framework, more reasoning rules need to be performed. Therefore, the authors may implement more algorithms in the framework to acquire more comprehensive context information.

Practical implications

CDRFM expands the context-awareness framework of previous research and unifies the procedures of acquiring, describing, modeling, reasoning and discovering implicit context information for mobile service providers.

Social implications

Support the service-oriented context-awareness function in application design and related development in commercial mobile software industry.

Originality/value

Extant researches on context awareness rarely considered the generation contextual information for service providers. The CDRFM can be used to generate valuable contextual information by implementing more reasoning rules.

Abstract

Purpose

In light of a growing trend towards mobile information management and a UK governmental drive for police forces to implement mobile technologies and realise significant benefits, it is important to examine the factors affecting officer acceptance. There appears to be little understanding of the key factors, yet this is critical to the success of the initiative. The purpose of this paper is to investigate the main factors that influence the usage of mobile technologies amongst police officers.

Design/methodology/approach

A qualitative, partially ethnographic design was followed to allow an in‐depth exploration of this issue. The study was based on a mixed‐methods longitudinal evaluation study of the implementation of mobile technologies within a UK police force over a nine‐month period. The technology acceptance model (TAM) and the subsequent TAM2 and TAM3, were then reengineered to provide a suitable theoretical model for a mobile policing context.

Findings

In total, four main categories of officer acceptance factors were identified: officer performance, security/reliability, management style and cognitive acceptance. Evidence from the study showed a key shortfall in all three versions of the TAM in that they focus on the user perspective and did not confirm the broader organisational factors within the implementation and social contexts of mobile policing.

Originality/value

Consequently, an adapted mobile‐TAM (m‐TAM) was produced that incorporated these factors into the existing TAM elements. The high‐level nature of the adapted model for mobile policing means it could be applied by other police forces and potentially other organisations, regardless of the type of mobile device implemented, to address the barriers to acceptance. The m‐TAM addresses the need for a more relevant and robust model to the mobile policing paradigm, which goes beyond the static technology environment in which the TAM2 and TAM3 were built.

Abstract

In this paper, we develop and evaluate an approach to assessing the content quality in a location‐based service (LBS). The proposed approach, instead of assessing the quality in absolute terms such as completeness or accuracy, measures the effect that the imperfection of the content is having on the reliability of that specific LBS. We apply the basic ideas from Software Reliability Engineering (SRE), but develop a modification of SRE, 2‐Branch, in order to separate content quality from other factors, such as positioning imprecision, and to reduce the measurement error. In our experimental study, we first compare 2‐Branch to the standard SRE, after which we experimentally analyze some properties of SRE methodology as such in the context of an LBS. The experiments indicate that 2‐Branch has in most cases a lower measurement error than the standard SRE. A corollary to that is that 2‐Branch can achieve, therefore, as low an error level as the standard SRE, using a worse and thus cheaper oracle. Getting a good oracle is probably the main cost factor in evaluating the quality of an information service, thus being able to use a cheaper one may result in significant savings.

Abstract

Purpose

The purpose of this paper is to investigate the role that agency culture, training, and supervision play in the rates of on-the-job seatbelt use among peace officers, as well as other officer safety-related driving concerns such as cell phone use, Mobile Data Terminal use, and other sources of distraction.

Design/methodology/approach

Based on semi-structured interviews with California peace officers.

Findings

This study found an array of agency culture issues related to on-duty collisions, including distraction, failure to follow policy or procedure, fatigue, self-selection processes among officers and agencies, supervision and field training processes, morale issues, and family/lifestyle issues.

Originality/value

To explain these agency culture findings, this paper introduces the concept of the “banality of risk” to understand why many officers choose not to use risk-attenuating equipment. The findings are suggestive of a set of best practices that agencies could consider regarding in-vehicle officer safety.

Abstract

Subject area

Business/technology strategy. The purpose of the case is to enable the students to understand the following: how technology implementation can change the face of business like cab service? How information technology deployment can influence competition? How investment in company's IT infrastructure affects the bottom line?

Study level/applicability

The case can be discussed at Master of Business Administration (MBA)/Post Graduate Diploma in Business Administration (PGDBA) level students as well as executive education program. It is aimed at graduate level and postgraduate level management courses such as management information systems, strategic information systems, and technology management.

Case overview

Meru Cabs, started in April 2007 at Mumbai, was one of the firsts to provide “radio taxi” service in India. Meru Cabs delivers a reliable taxi service by concentrating on three C's, namely customer, call centre and chauffeur. Much of its growth can be attributed to successful deployment of the technology. This case presents the growth of Meru Cabs and how it has differentiated itself by utilizing the technology to attain market leader position in the four cities – Mumbai, Delhi, Hyderabad and Bangalore, where it operates. Also the case discusses about the future of cab service in general and what it has in store for Meru Cabs. With the flurry of cabs service coming up in every city and the competition getting intense, the case put forth the opportunities and challenges existing for cab companies in general and Meru Cabs in particular.

Expected learning outcomes

To enable the students to understand that technology is a strategic tool: to enhance customer relationship, to manage business operations, to achieve sustained competitive advantage and that forms an integral part of company's growth and/or expansion strategy.
