Abstract Introduction A validated visual field chart designed as a simpler adjunct to formal perimeters is being developed into an app. The app aims to empower patients with pituitary tumours to independently assess their central 25˚ visual field with intra-app instructions and share their results with their clinician. NHSx marked usability as an assessment criterion for validating health apps. This study aims to explore and improve the usability of the beta-version of the app. Method Qualitative methods were employed through observation and semi-structured interviews. Recruitment was through convenience sampling. Participants experienced the app solely based on the intra-app information. Meanwhile, a researcher observed the process. Then, qualitative feedback was generated through semi-structured interviews. Observational data was coded and quantified. Thematic analysis was employed to identify common themes and/or categories of the qualitative feedback. Results 15 participants between 24-58(mean 33.7, SD 10.8) years were recruited. Observational data revealed that 1/15 adhered to all 3 written instructions; 3/15 utilised the hand span distance guidance provided. Participants’ responses on feedback for improvements were coded and categorised. Suggested additional features for improvement – a run-through introduction to the app, a video example of how to conduct the test, a practice run, an option for audio instruction and an option to change font size and type. Suggested additional instructions were to focus on the black dot and remember what you were seeing with the red dots. Conclusions Qualitative methods identified aspects of the app requiring improvements. Participants feedback will be utilised to improve the app.

Introduction The paper Cullen chart has been a validated adjunct to perimeters in detecting scotomas for various neuro-ophthalmological pathologies for decades. It was digitized into a prototype-app to empower future users to conduct remote monitoring of visual fields. This project aimed to refine the apps' usability for future users to self-assess and monitor their visual fields by exploring the difficulties faced using the app, to gather feedback, and subsequently to improve its usability for future iterations to objectively compare iterations using the MAUQ scores. Methods Participants (n = 15; age: 24-58) recruited through convenience sampling underwent mixed (quantitative and qualitative) methods to measure 1. Participants' adherence to the app instruction through observation, 2. objective experiences of using the app through self-reporting using the mHealth App Usability Questionnaire (MAUQ), and 3. Subjective experience of app using through semi-structured interviews. Descriptive analysis was computed for observation and MAUQ data. Thematic analysis was adopted to analyse the semi-structured interview data. Results 1/15 adhered to 3 written instructions and 8/15 participants had awkward hand movements. The MAUQ median score was 123/147, the MAUQ domain mean scores - ease of use and satisfaction, system information arrangement and usefulness were 81.6%(45.7/56), 80.6%(33.9/42) and 80.2%(39.3/49), respectively. Questions 4, 5, 9, 11 and 19 were the 5 lowest-scoring questions. Qualitative data were categorised into instructions, test, and feedback which had codes and subcodes. Conclusion Feedback for improvements were surrounding central fixation, remembering peripheral stimuli, uncover eye when interacting with peripheral stimuli, video examples, an introduction to the app and audio instructions.

Estimates of cylindrocladium root rot losses in three black and three white spruce compartments at five Ontario bare-root nurseries were determined through visual field assessment and seedling isolation. The causal fungus, Cylindrocladiumfloridanum Sob. & C.P. Seym., was isolated from 10–77% of the symptomatic and 0–28% of the apparently healthy seedlings in each compartment. In five compartments, estimates of mean incidence based on seedling isolations and visual assessment, were higher than those based on visual assessment alone. The percentage of living spruce (apparently healthy or symptomatic) estimated to be infected in each compartment was 0.1–32.7%. No fungus isolations were attempted from dead seedlings. Mortality in the plots in the six compartments was 0.02–17.7%. The correlation between the level of Cylindrocladium incidence and the inoculum density was significant (p < 0.01) in two compartments. The use of inoculum density to predict disease incidence warrants further investigation.

The aim of this study was to examine the relationship between the burnout levels of music teachers and their personalities. The research consisted of 278 music teachers who were selected from various places throughout Turkey via subjective, convenience sampling method. For data collection, the ‘Personal Information Form’, ‘Adjective Based Personality Test’ and ‘Maslach Burnout Scale’ were used. The research involved both quantitative and qualitative dimensions. The data were analyzed by quantitative t-test, multiple regression analysis and Pearson's correlation coefficient. Data for the qualitative dimension of the research were obtained from semi-structured interviews conducted with 5 music teachers. Negative, significant relationships were determined between extroversion, conscientiousness, agreeableness, openness and general burnout, while a positive, significant relationship was determined between neuroticism and general burnout. The burnout variable was found to have a statistically significant effect on the openness, neuroticism and conscientiousness dimensions of the personality types. The effects of conscientiousness and openness dimensions were not, however, found to be significant. The music teachers who had characteristics of extroversion and conscientiousness were found to have higher levels of burnout if they have the characteristics of neuroticism that reduce their exhaustion. The findings of the research show that the effect of personality types on burnout is important.

As a country surrounded by oceans, Indonesia has huge potential in salt production, and Sumenep district is one of the districts with the largest salt production in Indonesia. However, the potential and large production results are not in accordance with the economic conditions of salt farmers. This is due to several things, one of which is because the selling price of salt is not in accordance with the HPP (Harga Pembelian Pemerintah) as well as guidance and assistance to increase the productivity of salt farmers who are lacking. This problem will have an impact on the welfare of salt farmers. This study aims to determine how the level of welfare of salt farmers in Sumenep district in the perspective of maqāṣid al-sharī'ah. This research was examined with descriptive qualitative methods. The data was collected through semi-structured interviews with salt farmers in Sumenep district, then analyzed using the maqāṣid al-sharī'ah approach. Thus, the level of welfare of salt farmers is measured in five aspects of maqāṣid al-sharī'ah; hifz al-din (guarding religion), hifz al-nafs (guarding life), hifz al-'aql (guarding thoughts), hifz al-nasl (guarding nasab) , and hifz al-mal (protect wealth). The results of this study are the welfare of salt farmers from the aspects of hifz al-din and hifz al-naslhave been achieved (prosperous), but from the aspects of hifz al-nafs, hifz al- 'aql, and hifz} al-mal has not been reached (not prosperous). Keywords: Welfare, maqāṣid al-sharī'ah, salt farmers.

Purpose The standard forms of construction contract are receiving greater attention in the management of projects scholarship as they probably influence the project success and project disputes. The extant literature suggests that the standard forms of construction contract are one of the top sources of disputes. The purpose of this paper is to examine the effectiveness of the standard forms of construction contract, FIDIC and NEC, in reducing disputes in the Palestinian construction industry. Design/methodology/approach The researchers have used qualitative methods to collect data and more specifically have undertaken 12 semi-structured interviews. Findings The study reveals that the standard forms of construction contract can be a tool to minimise disputes, but certainly not to eradicate them, and NEC appears to be more capable than FIDIC to do so. Originality/value This study contributes to knowledge by bringing an industrial perspective into the role of standard forms of contract in disputes creation and avoidance. The interviewees, recurrent users of FIDIC contract, criticised certain features and expressions and proposed some solutions.

In Turkey today, one of the most frequently mentioned issues in the media is the influx of refugees, mostly from Syria. While most refugees are attempting to reach Europe by crossing through Turkey illegally, some consider Turkey an asylum center. This study used a phenomenological approach and qualitative experiment to determine how the phenomenon of refugeehood discussed in the media in Turkey affects children’s views on the issue. The sample was determined using the convenience sampling method, and 31 seventh-grade students (18 girls and 13 boys, all aged 14 years old) were selected. “Having previously met refugees” was used as a basic criterion in the selection of students, while classroom activities, letters, and semi-structured interviews were used to collect data. Descriptive and content analyses revealed that there were both positive and negative changes in students’ views regarding refugees, depending on the content of the news in the media, which was an important factor in influencing these changes.

Abstract Background Physical activity is recommended in the management of cystic fibrosis (CF). The aim of this study was to explore motives, barriers and enablers to physical activity among this population. Methods: Twelve participants (12–18 years) were recruited via convenience sampling. Photo-elicitation alongside semi-structured interviews were used to explore participants’ views and experiences of physical activity. Results Our findings revealed motives for physical activity including health, enjoyment and autonomy. Those with families who valued physical activity tended to have positive attitudes towards physical activity, and valued and integrated it into their lives. Moreover, they were likely to be intrinsically motivated to be active. Several factors enable and act as barriers to physical activity. Whilst CF influenced physical activity, the majority of enablers and barriers raised where congruent with the general populations. Conclusion This study provides support that healthcare providers should encourage both young people with CF and their families to be active, and subsequently informs the development of clinical interventions to support physical activity among young people with CF and their families.
