Abstract Objectives To examine the various roles of radiologists in different steps of developing artificial intelligence (AI) applications. Materials and methods Through the case study of eight companies active in developing AI applications for radiology, in different regions (Europe, Asia, and North America), we conducted 17 semi-structured interviews and collected data from documents. Based on systematic thematic analysis, we identified various roles of radiologists. We describe how each role happens across the companies and what factors impact how and when these roles emerge. Results We identified 9 roles that radiologists play in different steps of developing AI applications: (1) problem finder (in 4 companies); (2) problem shaper (in 3 companies); (3) problem dominator (in 1 company); (4) data researcher (in 2 companies); (5) data labeler (in 3 companies); (6) data quality controller (in 2 companies); (7) algorithm shaper (in 3 companies); (8) algorithm tester (in 6 companies); and (9) AI researcher (in 1 company). Conclusions Radiologists can play a wide range of roles in the development of AI applications. How actively they are engaged and the way they are interacting with the development teams significantly vary across the cases. Radiologists need to become proactive in engaging in the development process and embrace new roles. Key Points • Radiologists can play a wide range of roles during the development of AI applications. • Both radiologists and developers need to be open to new roles and ways of interacting during the development process. • The availability of resources, time, expertise, and trust are key factors that impact how actively radiologists play roles in the development process.

This study was conducted in response to the lack of green office buildings in Malaysia, despite the fact that the green concept has been initiated in Malaysia for many years. The Penang State Government has taken the initiative to establish the Penang Green Council (PGC) as the first state in Malaysia, and the implementation of green offices is one of its programme initiatives. Nonetheless, green offices are still in scarcity across Penang. This study identified the challenges faced in implementing green offices. Data were collected from five green building owners using semi-structured interviews and the data were analysed using thematic analysis. The outcomes revealed that the main challenges faced by green office adoption were lack of budget, lack of awareness, lack of expertise, ownership factor, and type of building. This study offers several implications for practitioners and policy makers to improve the adoption of green office in Malaysia. The results may be applied to raise awareness amongst practitioners and office owners regarding green practices in office buildings. The study outcomes may serve as reference to policy makers on enhancing the development of green buildings.

Business-IT alignment (BITA) continues to be a top management concern for the last ten years. Moreover, organizations mangers are still looking to understand the barriers between the status of alignment and misalignment. The barriers in BITA differ from a business area to another and particularly the authors have not found any research studies concerning the barriers in BITA in the manufacturing area in Sweden. Therefore, the research question is: What are the strategic, tactical, and operational barriers in business-IT alignment in a large company in manufacturing area? The research strategy is case study, and the data was collected through semi-structured interviews and also from company's internal documents and it was analyzed using thematic analysis. The findings of this study are a number of thirty barriers in BITA that includes six new barriers in BITA at operational, tactical and strategic level.

Nowadays, sustainable development is considered a key concept and solution in creating a promising and prosperous future for human societies. Nevertheless, there are some predicted and unpredicted problems that epidemic diseases are real and complex problems. Hence, in this research work, a serious challenge in the sustainable development process was investigated using the classification of confirmed cases of COVID-19 (new version of Coronavirus) as one of the epidemic diseases. Hence, binary classification modeling was used by the group method of data handling (GMDH) type of neural network as one of the artificial intelligence methods. For this purpose, the Hubei province in China was selected as a case study to construct the proposed model, and some important factors, namely maximum, minimum, and average daily temperature, the density of a city, relative humidity, and wind speed, were considered as the input dataset, and the number of confirmed cases was selected as the output dataset for 30 days. The proposed binary classification model provides higher performance capacity in predicting the confirmed cases. In addition, regression analysis has been done and the trend of confirmed cases compared with the fluctuations of daily weather parameters (wind, humidity, and average temperature). The results demonstrated that the relative humidity and maximum daily temperature had the highest impact on the confirmed cases. The relative humidity in the main case study, with an average of 77.9%, affected positively, and maximum daily temperature, with an average of 15.4 °C, affected negatively, the confirmed cases.

Research Analysis

This study was conducted with a team of senior managers at a Korean shipyard in an effort to elicit particular motivators for implementing management by walking around (MBWA). To identify the key motivators and communication issues associated with them, a theoretical framework was produced based on the key tensions of social psychology of communication and upward communication as well as modern organizational theories. For this qualitative research analysis, 12 semi-structured interviews were conducted face-to-face with the executives; the data were then supplemented by five field observations during MBWAs at the shipyard. Coding frame was used to organize modal salient themes for thematic analysis. The organizational and individual motivators identified were then analyzed in-depth to elicit communicational factors underlying these motivators. While identifying 10 salient motivators as organizing themes, the research concludes that MBWA is a contingent management strategy intended to promote upward communication within organizations.

We describe a case study that was conducted at the University of Ljubljana with the aim of studying the behavior of development teams using Scrum for the first time, i.e., a situation typical for software companies trying to introduce Scrum into their development process. 13 student teams were required to develop an almost real project strictly using Scrum. The data on project management activities were collected in order to measure the amount of work completed, compliance with the release and iteration plans, and ability of effort estimation, thus contributing to evidence-based assessment of the typical Scrum processes. It was found that the initial plans and effort estimates were over-optimistic, but the abilities of estimating and planning improved from Sprint to Sprint. Most teams were able to define almost accurate Sprint plans after three Sprints. In the third Sprint the velocity stabilized and the actual achievement almost completely matched the plan.

Although the use of artificial intelligence (AI) in healthcare is still in its early stages, it is important to understand the factors influencing its adoption. Using a qualitative multi-case study of three hospitals in China, we explored the research of factors affecting AI adoption from a social power perspective with consideration of the learning algorithm abilities of AI systems. Data were collected through semi-structured interviews, participative observations, and document analysis, and analyzed using NVivo 11. We classified six social powers into knowledge-based and non-knowledge-based power structures, revealing a social power pattern related to the learning algorithm ability of AI.

This qualitative case study explores early childhood pre-service educators' perceptions of using play-based teaching strategy across the Foundation Phase. A play-based approach promotes a special mode of thinking, sense of possibility, ownership, control, and competence in maths and PE learners. That is why scholars believe that hybrid pedagogical content knowledge that integrates play-based learning sustains learner attention throughout the lesson and promotes problem-solving skills. Therefore, the main objective of this study is to propose alternative pathways that promote the implementation of a hybrid pedagogical teaching strategy in the Foundation Phase. This study draws from a qualitative case study conducted at one of the universities in KwaZulu-Natal to explore the perception of pre-service teachers about using a play-based teaching strategy in pre-Grade R and Grade R classes. Five preservice teachers who teach both mathematics and PE were purposively and conveniently sampled to generate data using narratives and semi-structured interviews to describe their perceptions and experiences. Zoom group meetings and WhatsApp one-on-one semi-structured interviews were used during the data generation process. The findings reveal that pre-service mathematics and PE teachers perceive play-based pedagogies as necessary to provide a wide range of opportunities for learners to learn to count, visualising groups, and problem-solving skills. They underscore the importance of drawing from a hybrid approach that draws strength from play-based learning to complement formal learning.

Abstract Caring for people using psychoactive substances is historically associated with segregatory practices, even with children and adolescents. This study aims to understand the place of care based on the discourse of adolescents. Participant observation and semi-structured interviews were conducted with six adolescent users of psychoactive substances met at a child and adolescent mental health service. The data were analyzed by thematic analysis and discussed in the light of analytical psychology and of the assumptions of the psychiatric reform. One can conclude that the place of care is not fixed, but depends on how it is carried out, understood, and received, and on how the relational processes are established in the service with the adolescent. From the therapeutic relationships built in the service, it can be understood as temenos, the safe and potentially therapeutic place, where the transformation and development process of the subjects can be supported.

This paper examines the complex interaction between island histories and island geographies by presenting a case study of Dongzhou Island, Hengyang, China, contextualized through several critical island events. Employing a wide range of methods including archival research, textual and media analysis, field and map observations, semi-structured interviews, and informal interaction, the research is broadly framed in the problematic of geographical memory consisting of hard island memory, soft island memory, and lived island memory. Particular attention is paid to the construction of Dongzhou Island’s cultural trauma based on three difficult island histories: mass killing, radical planning, and uneven development. Findings indicate that these memories coexist on or about the island, in virtual isolation from each other. It is argued that while hard memory constructs the island as a petrified landmark, soft memories murmur about the forgotten or obscured pains of a small island that bears witness to the violence of war and progress. The theoretical and practical implications regarding the role of place memory in rejuvenating local cultures are also proposed.

The Right

Rapid changes on the way people travel the world have impacted countries around the globe. In South East Asia for example, with the rapid expansion of visit-a-country campaign exercises, it had affected the lives of people in many different ways. Tourism industry, for example, flourishes in manifolds. It indirectly changes the socioeconomic status of people of various echelons. Vietnam is no exception. The ease of communication has been identified as one of the key factors that attract tourists to places of choice. The issue is now whether Vietnamese, especially their youths are entirely ready to embrace this new wave of transformation. Therefore, the right moves have to be identified so that the number of tourists will multiple in the thousands if not millions. Therefore, the purpose of this investigation is to explore Vietnamese youths’ acceptance to learning the English language for communication, especially those encircling tourists’ spots with the right forms of communication to welcome the inflow of visitors around their communities. A qualitative design was used in this investigation employing semi-structured interviews, observations, and series of workshop sessions. The findings revealed that without proper curriculum instructions in school, although with passion and motivation, the youth will not be equipped as much as expected. Suggestions for future direction of this investigation are outlined.
