Abstract

Purpose

This study aims to, firstly, develop a red flag checklist for cryptocurrency Ponzi schemes and, secondly, to test this red flag checklist against publicly available marketing material for Mirror Trading International (MTI). The red flag checklist test seeks to establish if MTI’s marketing material posted on YouTube® (in the form of a live video presentation) exhibits any of the red flags from the checklist.

Design/methodology/approach

The study uses a structured literature review and qualitative analysis of red flags for Ponzi and cryptocurrency Ponzi schemes.

Findings

A research lacuna was discovered with regard to cryptocurrency Ponzi scheme red flags. By means of a structured literature review, journal papers were identified that listed and discussed Ponzi scheme red flags. The red flags from the identified journal papers were subsequently used in a qualitative analysis. The analyses and syntheses resulted in the development of a red flag checklist for cryptocurrency Ponzi schemes, with five red flag categories, containing 18 associated red flags. The red flag checklist was then tested against MTI’s marketing material (a transcription of a live YouTube presentation). The test resulted in MTI’s marketing material exhibiting 88% of the red flags contained within the checklist.

Research limitations/implications

The inherent limitations in the design of using a structured literature review and the lack of research regarding the cryptocurrency Ponzi scheme red flags.

Practical implications

The study provides a red flag checklist for cryptocurrency Ponzi schemes. The red flag checklist can be applied to a cryptocurrency investment scheme’s marketing material to establish if it exhibits any of these red flags.

Social implications

The red flag checklist can be applied to a cryptocurrency investment scheme’s marketing material to establish if it exhibits any of these red flags.

Originality/value

The study provides a red flag checklist for cryptocurrency Ponzi schemes.

Abstract

Purpose

Assessment of complex clinical skills and abilities is a challenge in mental health education. In the present study, an objective structured clinical examination (OSCE) was adapted to psychology and implemented in a Master in Psychology program. The purpose of the present study was to examine aspects of validity of this OSCE.

Design/methodology/approach

A total of 55 students enrolled in the Master in the Psychology program at Umeå University, Sweden, participated in two OSCE occasions. In addition to OSCE data, questionnaires were administered immediately after the OSCE to students (n = 18) and examiners (n = 13) to examine their perceptions of the OSCE.

Findings

The results provided support for different aspects of validity. The level of internal consistency was close to acceptable, and there was a good correspondence between global ratings and checklist scores for many stations. However, adding an additional category to the global rating scale and reviewing some of the station checklists might improve the assessment further. The present cut-score of the OSCE was comparable to a cut-score set by the borderline regression model. In general, students and examiners perceived the OSCE as a high-quality examination, although examiners raised some issues that could improve the OSCE further.

Originality/value

In conclusion, OSCE is a promising assessment in psychology, both from a psychometric perspective and from a test-taker and examiner perspective. The present study is an important contribution to the field as there are only a few examples where OSCE has been used in clinical psychology, and to the best of the authors’ knowledge, this paper is the first to evaluate the validity of such an assessment.

Abstract

A key strategy for improving the quality of mental health care is the design and implementation of a mechanism for on-site inspection and clinical auditing. We discuss the use of checklists in auditing providing an objective, comprehensive system for recording and analyzing multi-disciplinary, clinical auditing in mental health services. We believe such an approach can identify potential risks and allow for better decision making.

Abstract

Purpose

This study aims to examine Saudi female students' attitude toward peer feedback activity in writing classes with a list of questions for the students to follow during the activity, and to investigate the challenges that may prevent the use of such activity in Saudi EFL classes.

Design/methodology/approach

This study used a mixed-methods to ensure the credibility of the data and obtain clear descriptions about the topic. The study instruments are (1) Writing Essays, (2) Writing Checklist, (3) Questionnaire and (4) Semi-structured interview. The data were analysis with SPSS and o 10 software.

Findings

The study results indicated that students had a positive attitude toward peer feedback with a checklist in EFL writing class. For instance, their second written essay (post) has improved and has fewer mistakes than the first one. Also, most of the participants stated that peer feedback has improved their writing quality and has enhanced their writing awareness of their weaknesses and mistakes. Moreover, the interview had highlighted the main challenges that could affect using peer feedback in writing class. Finally, the results indicate the efficiency of peer feedback with a checklist in similar teaching contexts.

Research limitations/implications

The study focused on a small number of participants (30 students). Besides, the study dealt with students at university level only and the study focused on female students.

Practical implications

Based on the study finding, it is recommended that peer feedback should be integrated in all EFL writing classes at all levels. Based on the study finding, it is recommended that peer feedback should be incorporated in all EFL writing classes at all levels. Using checklist can help the students to become more independent learners and in time they will be able to correct their own mistakes.

Originality/value

This paper fulfills an identified need to identify how integrating peer feedback activity in writing class can improve the students' writing performance and help them to be independent learners.

Abstract

Purpose

Archaeological sites and monuments, by their nature, do not allow major interventions to their structure, in order to abolish the obstacles that make them inaccessible. Any interventions should be made sensitively and carefully, so as not to alter the monument’s character or damage it, either visually or structurally. The project “PROSPELASIS” focused on creating a methodology for facing monuments’ accessibility and perceptibility problems for people with disabilities and testing its application at Byzantine monuments of Thessaloniki. The paper aims to discuss these issues.

Design/methodology/approach

The creation of the proposed methodology was based on both research in relevant bibliography and the application of a form of “Delphi method” among involved actors. In this process persons specialized in accessibility and disability issues, persons with disability themselves, as well as employees of the 9th Ephorate of Byzantine Antiquities, archaeologists and experts in monuments’ restoration, participated.

Findings

The possible sites of interest for visitors with disabilities examined amount to 20 monuments which document the evolution of Byzantine architecture and are included in UNESCO’s World Heritage List. In six major monuments (Acheiropoietos, Saint Demetrios, Saint Nicholaos Orphanos, Hagia Sofia, Rotunda, Heptapyrgion Fortress) significant accessibility improvements were realized in order to verify the methodology proposed.

Practical implications

A practical tool for improving monuments’ accessibility has been developed, open for use by any interested body.

Social implications

The application of the methodology developed is beneficial for the promotion of the equality and non-discrimination principles.

Originality/value

The successful implementation of the proposed methodology and the importance that accessibility improvement of monumental sites has in the attraction of visitors with restricted mobility and perceptibility and the development of accessible tourism, constitute the results of this project not only pertinent to Thessaloniki or Greece, but worthy of a wider application.

Abstract

Purpose

There is immense potential in open educational resources (OER) for encouraging systemic change within academic institutions toward increasing access and equity in education. The purpose of this paper is to propose an empirical framework and a checklist for mainstreaming OER in an academic institution.

Design/methodology/approach

The empirical framework and the mainstreaming checklist is formulated based on an extensive review of literature and case studies strengthened by the author’s personal experience as an academic, researcher, practitioner, policymaker and international development expert in the field of OER.

Findings

The proposed empirical framework and OER mainstreaming checklist identifies several processes to be completed by key stakeholders for successful mainstreaming of OER in an academic institution.

Practical implications

The proposed framework assumes that the institution which is undergoing mainstreaming of OER follows the principles of outcomes-based education and that it has an established mechanism for measuring the mastery of learning outcomes and the role of OER in accreditation.

Originality/value

One key feature of the framework is its horizontal structure where stakeholders take a team-based approach to completing the required tasks for mainstreaming OER. This, in turn, increases ownership of the mainstreaming process leading to higher success rates and sustainability. Second, the mainstreaming checklist breaks down each process into several achievable tasks and assigns them to the relevant team. Third, the framework supports continuous quality improvement which encourages institutions to periodically revisit the processes to make necessary course corrections and enhancements.

Abstract

Purpose

As occupational therapists embrace evidence-informed and occupation-centred practice, the use of standardised visual perceptual tests remains a strong feature of typical paediatric practice. Yet, the research evidence for the use of such tools is inconclusive at best. This study compared the results of the Test of Visual Perceptual Skills (TVPS) with a checklist of reported functional difficulties in 30 children attending occupational therapy. The purpose of this paper was to determine the usefulness of visual perceptual testing in relation to occupation-centred practice.

Design/methodology/approach

A descriptive correlational study design was used. Participants were 30 primary school-age children who were on a paediatric occupational therapy caseload. An additional 30 typically developing children participated in the development of the checklist.

Findings

Correlations were found between reported functional visual skill difficulties and two subtests of the TVPS (visual memory and visual discrimination). No correlation was found between the reported functional difficulties and any of the other five subtests of the TVPS or the total score.

Originality/value

Results highlight the weak relationship that existed in this study between standardised measures of visual perception, as measured by the TVPS, and functional difficulties. Therapists are cautioned to explore both the evidence base for continued use of standardised visual perceptual measures to inform occupation-centred practice and the need to embrace a more comprehensive person-centred approach to visual perceptual assessment.

Abstract

Purpose

This study aims to explore the viability of using C-17 reduced-engine taxi procedures from a cost savings and capability perspective.

Design/methodology/approach

This study model expected engine fuel flow based on the number of operational engines, aircraft gross weight (GW) and average aircraft groundspeed. Using this model, the research executes a cost savings simulation estimating the expected annual savings produced by the proposed taxi methodology. Operational and safety risks are also considered.

Findings

The results indicate that significant fuel and costs savings are available via the employment of reduced-engine taxi procedures. On an annual basis, the mobility air force has the capacity to save approximately 1.18 million gallons of jet fuel per year ($2.66m in annual fuel costs at current rates) without significant risk to operations. The two-engine taxi methodology has the ability to generate capable taxi thrust for a maximum GW C-17 with nearly zero risks.

Research limitations/implications

This research was limited to C-17 procedures and efficiency improvements specifically, although it suggests that other military aircraft could benefit from these findings as is evident in the commercial airline industry.

Practical implications

This research recommends coordination with the original equipment manufacturer to rework checklists and flight manuals, development of a fleet-wide training program and evaluation of future aircraft recapitalization requirements intended to exploit and maximize aircraft surface operation savings.

Originality/value

If implemented, the proposed changes would benefit the society as government resources could be spent elsewhere and the impact on the environment would be reduced. This research conducted a rigorous analysis of the suitability of implementing a civilian airline’s best practice into US Air Force operations.

Abstract

Considerably diminished quality of life (QoL) is observed in patients with visual field defects after lesions affecting the visual pathway. But little is known to what extent vision-and health-related QoL impairments are associated with psychological distress. In 24 patients with chronic visual field defects (mean age=56.17±12.36) the National Eye Institute-visual functioning questionnaire (NEI-VFQ) for vision-related QoL, the Short Form Health Survey-36 (SF-36) for generic QoL and the revised Symptom-Checklist (SCL-90-R) were administered. Cases with clinically relevant SCL-90-R symptoms were defined. Demographic, QoL and visual field parameters were correlated with SCL-90-R scales. About 40% of the investigated patients met the criteria for the definition of psychiatric caseness. 8/12 NEI-VFQ scales correlated significantly with SCL-90-R phobic anxiety (r-range -0.41 to -0.64, P<0.05), 5/12 NEI-VFQ scales correlated with SCL-90-R interpersonal sensitivity (-0.43 to -0.50), and 3/12 with SCL-90-R depression (-0.51 to -0.57) and obsessive-compulsiveness (-0.41 to -0.43). In contrast, only 1/8 SF-36 scales correlated significantly with SCL-90-R depression, phobic anxiety and interpersonal sensitivity (-0.41 to -0.54). No substantial correlations were observed between visual field parameters and SCL-90-R scales. Significant correlations of SCL-90-R with NEI-VFQ but not with SF-36 suggest that self-rated psychological distress is the result of diminished vision-related QoL as a consequence of visual field loss. The extent of visual field loss itself did not influence the rating of psychological distress directly, since SCL-90-R symptoms were only reported when diminished vision-related QoL was present. Patients with reduced vision-related QoL due to persisting visual field defects should therefore be offered additional neuropsychological rehabilitation and supportive psychotherapeutic interventions even years after the lesion.
