Abstract

Purpose

The purpose of this article is to identify how the organisations are able to improve their business value through acquisition of business analytics capabilities and by improving their performance.

Design/methodology/approach

With the help of literature survey, along with standard resource-based view framework, a conceptual model has been developed. These have been statistically tested by collecting the data using the survey questionnaire from 306 selected respondents from various service sector- and product-based organisations in India. To analyse the data we have used partial least square–based structural equation modelling.

Findings

The study highlights that by the help of data acquisition and tool acquisition as two vital components the acquisition of business analytics capabilities could improve the business value of the organisation by strengthening its organisational performance. The findings of this research also indicated that acquisition of business analytics capabilities has a significant influence on an organisation's business process performance and business decision, which in turn significantly influences organisational performance. And organisational performance eventually positively influences its business value. The model was found to provide an explanative power of 71%.

Research limitations/implications

The proposed research model can provide effective recommendations to the management of the organisations to realise the importance of acquisition of effective business analytics capabilities to eventually improve the business value of the organisation.

Originality/value

No specific studies, as yet, have analysed the effects of acquisition of business analytics capabilities for improving organisational performance mediated through business process performance and business decision. Therefore, this research has explored the distinctive effort to empirically validate this understanding.

Abstract

Purpose

The purpose of this paper is to propose an approach that helps in acquisition of live data as well as data stored in the internal/external memory of android mobile device considering that the data on the device are not much altered during the extraction process. Also, the emphasis is laid on testing the validity of existing forensic tools against the data obtained manually and by using this approach. Smartphones have spurred the mobile computing technology, and Android is widely used as an Operating System in these devices. These days, users store most of their personal information like emails, images, contacts etc., on Phones/Tablets as their data would be readily accessible and thus convenient for them.

Design/methodology/approach

Android Operating System is built on the Linux Kernel and scripts to extract data from Android Mobile Device with the use of Android Debugging Bridge have been written. The approach is more focused on the logical acquisition of data from devices rather than acquisition using physical methods.

Findings

Live data of the Facebook application running on the device can be extracted. Also, the password of the LuksManager application (used to create an encrypted volume on the device), which is stored in the internal memory, is also extracted and identified.

Research limitations/implications

The study has been conducted in an academic environment, thereby limiting external validity. Another limitation is the limited edition of some of the software forensics tools that are used. The full access to these software tools are restricted by Law enforcement and Investigation policies. The research provides a different approach which could aid in criminal investigation activities on mobile devices.

Practical implications

The devices which have the latest versions of Android not only store messages and mails, but a lot of information about GPS, as well as information about popular applications like Facebook, WhatsApp, etc. This could practically help a lot in criminal investigation.

Originality/value

This study is important because very few works have been done on recent versions (Jellybean and Kitkat) of Android. The proposed approach could extract large amounts of information as compared to earlier approaches with the newer versions of Android having larger memory and new features.

Abstract

Although the focus of this issue is on investment in British industry and hence we are particularly concerned with debt and shares, the transactions and holdings in these cannot be separated from the range of other financial claims, including property, that are available to investors. In consequence this article focuses on an overview of the financial system including in Section 2 a presentation of the flow of funds matrix of the financial claims that make up the system. We also examine more closely the role of the financial institutions that are part of the system by utilising the sources and uses statements for three sectors, non‐bank financial institutions, personal sector and industrial and commercial companies. Then we provide, in Section 3, a discussion of the various financial claims investors can hold. In Section 4 we give a portrayal of the portfolio disposition of each of the major types of financial institution involved in the market for company securities specifically insurance companies (life and general), pension funds, unit and investment trusts, and in Section 4 a market study is performed for ordinary shares, debentures and preference shares for holdings, net acquisitions and purchases/sales. A review of some of the empirical evidence on the financial institutions is presented in Section 5 and Section 6 is by way of a conclusion. The data series extend in the main from 1966 to 1981, though at the time of writing, some 1981 data are still unavailable. In addition, the point needs to be made that the samples have been constantly revised so that care needs to be exercised in the use of the data.

Abstract

Federal agencies are relying increasingly on contractors to perform their missions. With hundreds of billions of tax dollars spent each year on goods and services, it is essential that federal acquisition be handled in an efficient, effective, and accountable manner. The Government Accountability Office (GAO), however--as well as other accountability organizations, inspectors general, and the agencies themselves--continue to identify systemic weaknesses in key areas of acquisition. In fact, the acquisition function at several agencies has been on GAO's high-risk list, which identifies areas in the federal government with greater vulnerability to fraud, waste, abuse, and mismanagement. In January 2005, we added interagency contracting to this list. Far too often, the result of poor acquisitions has been an inability to obtain quality goods and services on time and at a fair price. We can no longer afford such outcomes. Given current fiscal demands and the fiscal challenges we are likely to face in the 21st century, the federal government must improve its ability to acquire goods and services in a cost-effective manner. GAO developed this framework to enable high-level, qualitative assessments of the strengths and weaknesses of the acquisition function at federal agencies. Such assessments can help senior agency executives identify areas needing greater management attention, and enable accountability organizations (including GAO) to identify areas requiring more focused follow-up work. The framework consists of four interrelated cornerstones that our work has shown are essential to an efficient, effective, and accountable acquisition process: (1) organizational alignment and leadership, (2) policies and processes, (3) human capital, and (4) knowledge and information management. The framework supports an integrated evaluation approach, but each of these cornerstones can stand alone so users of this framework may tailor evaluations to an agency's specific needs.

Abstract

Purpose

The purpose of this paper is to present the research efforts of the Center of Aeronautical Studies of the Federal University of Minas Gerais – Brazil to develop a low‐cost flight test data acquisition system for light aircraft and unmanned aerial vehicles (UAEs).

Design/methodology/approach

The development of this system was based on a microcontroller, chosen in accordance with main requirements of light aircrafts flight tests. The system uses the microcontroller in order to communicate with different kinds of sensors, including a GPS, and organize this information to be sent to a PDA device, which is used to control the acquisition process and storage the data acquired. Details about the development of this system, including firmware algorithm and sensors development, are presented and discussed in the paper.

Findings

The paper presents example results obtained with this system in applications such as performance evaluation and stability and control derivatives estimation problems. Take into account all the aspects of the system and the quality of the results, the main conclusion is that this system can efficiently support the demands of the aerospace industry for light aircraft and UAEs development programs as well as the necessities of the research centers and universities developing aeronautical research and didactic programs.

Practical implications

Recently, results confirm the applicability of this system in order to perform flight tests of aircrafts in accordance with FAR‐Part 23 or CS‐VLA or Light Sport Aircrafts as required by FAA Order 8130.2F and ASTM Designation F2245‐04.

Originality/value

This paper presents details about the construction of a low‐cost data acquisition system for flight tests of light aircrafts. The main advantage of this system is the use of a PDA device in order to control and storage the acquisition, which reduce costs, weight and size of the system and permits its installation in light aircrafts or UAVs.

Abstract

Purpose

This paper aims to expand knowledge on strategy and business model transformation by exploring how the increased data availability can threaten the competitive positioning of data-based firms.

Design/methodology/approach

The study uses two longitudinal cases design. The data include a review of 270 business acquisitions performed by IBM and Yahoo! between 1995 and 2018 relying on publicly available documentation, corporate annual reports, shareholders presentations and press releases.

Findings

The study provides insights into how the availability of data can affect business models and the competitive advantage of data-based firms. Successful business model transformation in data-based firms appear to be contingent on dual-purpose mergers and acquisitions (M&As), oriented toward data and data-processing activities.

Research limitations/implications

Inductive case studies yield results that require quantitative validation. The insights on business model transformation and M&As from this study were obtained within the context of data-intensive firms.

Practical implications

When formulating a growth strategy through M&As, strategists need to consider whether the current state of their competitive positioning requires single purpose acquisitions (e.g. data or data-processing capabilities) or dual-purpose acquisitions.

Originality/value

As data becomes a commoditized asset, further research and guidance are needed to assess the impact of this phenomenon on data-based business models. This study fulfills an identified need to gain insights into the relationship between business model transformation and M&A activity.

Abstract

Smiths Industries Aerospace (SI) offers a multi‐aircraft capable generic health and usage monitoring system (GenHUMS) using field proven, off‐the‐shelf, airborne and ground‐based technology. The UK Ministry of Defence (MoD) has selected the GenHUMS for the Chinook aircraft with additional options for Puma, Sea King and Lynx aircraft. The GenHUMS provides all conventional HUMS functionality, and incorporates key innovation in the areas of rotor track and balance, failure detection, flight regime recognition, alert generation, system configurability, and user interface. The architecture is unique in that all required airborne data acquisition and processing, including crash survivable cockpit voice and flight data recording, are combined in a single line replaceable unit. This architecture significantly reduces space, weight and power requirements and results in the highest reliability, least risk, lowest life cycle cost, HUMS known today. Fixed and portable PC‐based HUMS ground stations provide configurable, user friendly, data extraction and analysis capabilities.

Abstract

Purpose

The purpose of this paper is to conduct a forensic analysis of Google Allo messenger on an Android-based mobile phone. The focus was on the analysis of the data stored by this application in the internal memory of the mobile device, with minimal use of third-party applications. The findings were compared with the already existing works on this topic. Android is the most popular operating system for mobile devices, and these devices often contain a massive amount of personal information about the user such as photos and contact details. Analysis of these applications is required in case of a forensic investigation and makes the process easier for forensic analysts.

Design/methodology/approach

Logical acquisition of the data stored by these applications was performed. A locked Android device was used for this purpose. Some scripts are presented to help in data acquisition using Android Debug Bridge (ADB). Manual forensic analysis of the device image was performed to see whether the activities carried out on these applications are stored in the internal memory of the device. A comparative analysis of an existing mobile forensic tool was also performed to show the effectiveness of the methodology adopted.

Findings

Forensic artifacts were recovered from Allo application. Multimedia content such as images were also retrieved from the internal memory.

Research limitations/implications

As this study was conducted for forensic analysis, it assumed that the mobile device used already has USB debugging enabled on it, although this might not be the applicable in some of the cases. This work provides an optimal approach to acquiring artifacts with minimal use of third-party applications.

Practical implications

Most of the mobile devices contain messaging application such as Allo installed. A large amount of personal information can be obtained from the forensic analysis of these applications, which can be useful in any criminal investigation.

Originality/value

This is the first study which focuses on the Google Allo application. The proposed methodology was able to extract almost as much as the data obtained using earlier approaches, but with minimal third-party application usage.

Abstract

Purpose

This paper aims to capture and manage the product lifecycle data for consumer products, especially data that occur in distribution, usage, maintenance and end‐of‐life stages, and to use them to provide information and knowledge.

Design/methodology/approach

A lifecycle information acquisition and management model is proposed, and an information management system framework is formulated. The information management system developed is then used in actual field trials to manage lifecycle data for refrigeration products and game consoles.

Findings

It has been demonstrated that valuable services can be delivered through a lifecycle information management system.

Practical implications

Lifecycle information management systems can open new horizons for product design which are sustainable and environmentally sensitive. They also contribute to the wider exploration of eco‐design and development of next generation consumer products (e.g. smart home appliances).

Originality/value

Existing lifecycle information systems cannot support all phases of the product lifecycle. They mainly manage the lifecycle data only during the design and manufacture stages. Lifecycle data during distribution, usage, maintenance and end‐of‐life stages are usually hard to acquire and in most cases lost. The lifecycle information management system developed can capture them, and manage them in an integrated and systematic manner to provide information and knowledge.

Abstract

Purpose

The purpose of this paper is to describe a model for the design and development of a condition-based maintenance (CBM) strategy for the cutting group of a labeling machine. The CBM aims to ensure the quality of labels' cut and overall machine performances.

Design/methodology/approach

In developing a complete CBM strategy, two main difficulties have to be overcome: (1) appropriately dealing with incomplete and low-quality production database and (2) selecting the most promising predictive model. The first issue has been addressed applying data cleansing operations and creating ad hoc methodology to enlarge the training data. The second issue has been handled developing and comparing an empirical model with a machine learning (ML)-based model; the comparison has been performed assessing capabilities thereof in predicting erroneous label cuts on data obtained from an operating plant located in Italy.

Findings

Research results showed that both empirical and ML-based approaches exhibit good performances in detecting the operating conditions of the cutting machine. The advantage of adopting an ML-based model is that it can be used not only as a condition indicator (i.e. a model able to continuously provide the health status of an asset) but also in predictive maintenance policies (i.e. a CBM carried out following a forecast of the degradation of the item).

Research limitations/implications

The study described in this manuscript has been developed on the practices of a labeling machine developed by an international company manufacturing bottling lines for beverage industry. The proposed approach might need some customization in case it is applied to other industries. Future researches can validate the applicability of such models on different rotary machines in other companies and similar industries.

Originality/value

The main contribution of this paper lies in the empirical demonstration of the benefits of CBM and predictive maintenance in manufacturing, through the overcoming of a specific production issue. The large number of variables involved in thin label cutting lines (film thickness between 30 and 38 µm), the high throughput and the high costs due to production interruptions render the prediction of non-conforming labels an economically relevant, albeit challenging, goal. Moreover, despite the large scientific literature on CBM in rolling bearing and face cutting movements, papers dealing with rotary labeling machines are very unusual and unique.
