Abstract
Purpose
The purpose of this paper is to present a localisation system for an indoor rotary‐wing micro aerial vehicle (MAV) that uses three onboard LEDs and base station mounted active vision unit.
Design/methodology/approach
A pair of blade mounted cyan LEDs and a tail mounted red LED are used as on‐board landmarks. A base station tracks the landmarks and estimates the pose of the MAV in real time by analysing images taken using an active vision unit. In each image, the ellipse formed by the cyan LEDs is used for 5 degree of freedom (DoF) pose estimation with yaw estimation from the red LED providing the 6th DoF.
Findings
About 1‐3.5 per cent localisation error of the MAV at various ranges, rolls and angular speeds less than 45°/s relative to the base station at known location indicates that the MAV can be accurately localised at 9‐12 Hz in an indoor environment.
Research limitations/implications
Line‐of‐sight between the base station and MAV is necessary while limited accuracy is evident in yaw estimation at long distances. Additional yaw sensors and dynamic zoom are among future work.
Practical implications
Provided an unmanned ground vehicle (UGV) as the base station equipped with its own localisation sensor, the developed system encourages the use of autonomous indoor rotary‐wing MAVs in various robotics applications, such as urban search and rescue.
Originality/value
The most significant contribution of this paper is the innovative LED configuration allowing full 6 DoF pose estimation using three LEDs, one camera and no fixed infrastructure. The active vision unit enables a wide range of observable flight as the ellipse generated by the cyan LEDs is recognisable from almost any direction.

Abstract
Purpose
The purpose of this paper is to gain in-depth understandings of the stages involved in the case of a romance scam victim who was unknowingly used as a drug mule. The work compares this case with established research in this field. It also seeks to learn more about the strategies used by these cybercriminals.
Design/methodology/approach
The research presents a case study of a victim of a romance scam who was arrested for drug trafficking. The research involves a grounded theory analysis of interviews with the victim, legal team and family members and analysis of her instant messenger chat logs and email communications.
Findings
The analysis identified a variation on previous stage models of romance scams and re-names this as the “romance scammers” strategy model. It also replicates previous work on scammers’ techniques and highlights some new strategies, including positively and negatively framing messages, unconditional positive regard, activating norms of romantic relationships, cognitive immersion, manipulating role, sleep deprivation and signing is believing.
Practical implications
These findings could be used to help guide future similar court cases. Moreover, they can be drawn upon to advance future research on romance scams, as well as scams in general.
Originality/value
This is the first in-depth case study of a romance scam victim involved in drug trafficking and is the first research on romance scams to examine in depth a case, taking into account textual exchanges. While not undermining previous research, this paper provides valuable insights that are lacking in previous qualitative work on cyber scam victims.

Abstract
Purpose
The purpose of this paper is to undertake an exploratory study on mapping the investment fraud methods and tactics used by scammers against the emerging literature on scam compliance.
Design/methodology/approach
Qualitative interviews were conducted with victims of investment fraud supported by the engagement of specialist counsellors and allied health professionals who specialise in scam victim support (including investment fraud).
Findings
Investment fraud offending in the cases sampled exhibited a number of dominant offending traits and methodological themes. These included a strong reliance or dependency on legitimate service provisioning on the part of the fraudster and the use of key trust measures to lure the victim. The empirical data revealed the presence of a number of scam compliance influences captured in the literature, including trust, social influence and urgency, as well as others not previously documented that pave the way for further research attention.
Research limitations/implications
The research only examined a sample of investment fraud victim experiences that engaged a national victim support service immediately following detection over a 24 month period.
Practical implications
The research found that offending relied upon the participation of trust-building signals and measures. Legitimate economy participants appear to play a dominant role in enabling investment scam activities, further creating efficiencies for criminals. The offending tended to follow a number of distinct but connected phases. Impacts were influenced by specific offending attributes, such as whether remote access was given to offenders of a victim’s device, as well as the nature of the identity credentials access.
Originality/value
The research has practically applied an emerging view of scam compliance influences and vulnerabilities within an investment fraud context. The study is novel in its thematic analysis of the distinct phases and tactics used by scammers.

Abstract
Purpose
This paper aims to demonstrate how to apply the systemic lessons learned knowledge (Syllk) model to enable the organisation for the capability of an online community of practice (CoP).
Design/methodology/approach
The research method consisted of multiple spiral “action research” cycles (plan, action, observe and reflect) within a government organisation. The initial planning stage consisted of interviews followed by two focus groups to identify the facilitators and barriers that impact the initial design of the Syllk model within the organisation. Established knowledge management practices were aligned with each of the Syllk elements to address the identified barriers and facilitate learning as the action cycles progressed. Online CoP initiatives were implemented with two action research cycles completed. Actions were observed, monitored, evaluated and reflected on using an after action review process.
Findings
The results from this research shows how the capability of a CoP can be “wired” (distributed) across organisational systems, and how the Syllk model can be used to conceptually facilitate this. The research highlights the importance in understanding organisational knowledge facilitators and barriers and the associated practices to reflect and learn from past experiences.
Research limitations/implications
The paper demonstrates an application of the Syllk model, and that action research can benefit project and knowledge management researchers and practitioners.
Practical implications
This study contributes to practice by highlighting how to use the Syllk model to “wire” an organisation for some know-how capability.
Originality/value
This study applies a conceptual model enabling management to understand how organisational know-how is distributed (wired) across various systems of an organisation for an online CoP.

Abstract
Purpose
The purpose of this paper is to create a “refined” (with unnecessary elements removed) definition of the term stakeholder, thereby removing confusion surrounding the use of this term from the general and project management arenas.
Design/methodology/approach
A method of deriving refined definitions for a group of terms by ensuring there are no unnecessary elements causing internal conflict or overlap is adopted and applied to resolve the confusion.
Findings
The refined definitions of stake and stakeholder are in terms of an interest and activity. This avoids all extensions of meaning introduced by defining particular types of stakeholders and/ or their degrees of impact. It also resolves the multiplicity of conflicting meanings possible when silent or assumed qualifiers of a word are ignored, restricting definition to, for example, project stakeholders or stakeholders of a firm. These definitions are carried forward into a mapping of the stakeholder locus of interest on an activity rather than a company base, enabling generic categorisation of stakeholders to be proposed for use in both private and public sectors. A governance difficulty with the term customer also emerged and a resolution to this is proposed.
Research limitations/implications
Resolution of the academic contention around the definition of stakeholders will facilitate future research endeavours by removing confusion surrounding the term. It can also provide clarity in governance arrangements in public and private sectors. Verification of the method used through its success in deriving this “refined” definition suggests its suitability for application to other contested terms.
Practical implications
Projects and businesses alike can benefit from removal of confusion around the definition of stakeholder in the academic research they fund and attempt to apply.
Social implications
A refined definition of the stakeholder concept will facilitate building social and physical systems and infrastructure, benefitting organisations, whether public, charitable or private.
Originality/value
Clarity results in the avoidance of confusion and misunderstanding together with their consequent waste of time, resources and money.

Abstract
Purpose
Effective project learning can prevent projects from repeating the same mistakes; however, knowledge codification is required for project-to-project learning to be up-scaled across the temporal, geographical and organisational barriers that constrain personalised learning. This paper explores the state of practice for the structuring of codified project learnings as concrete boundary objects with the capacity to enable externalised project-to-project learning across complex boundaries. Cross-domain reconceptualisation is proposed to enable further research and support the future development of standardised recommendations for boundary objects that can enable project-to-project learning at scale.
Design/methodology/approach
An integrative literature review method has been applied, considering knowledge, project learning and boundary object scholarship as state-of-practice sources.
Findings
It is found that the extensive body of boundary object literature developed over the last three decades has not yet examined the internal structural characteristics of concrete boundary objects for project-to-project learning and boundary-spanning capacity. Through a synthesis of the dispersed structural characteristic recommendations that have been made across examined domains, a reconceptualised schema of 30 discrete characteristics associated with boundary-spanning capacity for project-to-project learning is proposed to support further investigation.
Originality/value
This review makes a novel contribution as a first cross-domain examination of the internal structural characteristics of concrete boundary objects for project-to-project learning. The authors provide directions for future research through the reconceptualisation of a novel schema and the identification of important and previously unidentified research gaps.

Abstract
Purpose
The purpose of this paper is to investigate the variety of affective emotions that are evoked in extant project management (PM) practitioners by various PM artefacts.
Design/methodology/approach
A phenomenological methodology is used for eliciting, through self‐reporting and observation of gesture, the affective responses and consequential emotions experienced by PM practitioners as they interact or recount previous interactions with various artefacts of PM.
Findings
This paper suggests that PM is prevalent in the Western corporate environment because project managers obtain an emotional affect from aspects of the PM experience, and project managers utilise various PM artefacts to emotionally manipulate their environment to their own advantage.
Practical implications
The paper argues for a PM environment which is founded on evidence‐based practices. It suggests that future research should explore the links between PM, social architecture and flow theory.
Originality/value
This paper advances the evolutionary framework for PM research.

Abstract
Following a high‐profile publicity campaign across South Tyneside aimed at professionals and patients, 52.4 per cent of all patients admitted with suspected myocardial infarction during a six‐month period received 300mg of aspirin. Twelve months later GPs’ performance had improved from 25 per cent to 52.9 per cent of patients directly admitted by GPs being prescribed aspirin when first seen. Following a definite myocardial infarction 78.4 per cent of patients were discharged taking 75mg of aspirin, with no valid reason for omission in 6.6 per cent of patients. Six months after discharge 71.8 per cent of patients were still taking aspirin. Twelve months later 90 per cent of discharged patients were taking aspirin. GP PACT data showed a marked increase in prescribing 75mg aspirin during the period. The use of a publicity campaign to disseminate the message to both professionals and patients has resulted in a beneficial increase in aspirin prescribing for myocardial infarction across the district.

Abstract
Purpose
This paper aims to discuss the issues surrounding educational monitoring systems.
Design/methodology/approach
This paper is a general review of the situation in Greece.
Findings
This paper suggests that a superior educational monitoring system aiming to alleviate educational and social inequalities as well as discrepancies between schools and/or between classrooms would rely on both attainment and progress criteria, as these criteria operate differently and allow to bring into the fore different aspects of problems/educational inadequacies.
Originality/value
The benefits and pitfalls associated with the employment of different criteria for educational monitoring are discussed, so that a new monitoring system can be suggested for the Greek setting of public primary and secondary schools.
