Diabetic retinopathy (DR) is one of the dangerous complications of diabetes. Its grade level must be tracked to manage its progress and to start the appropriate decision for treatment in time. Effective automated methods for the detection of DR and the classification of its severity stage are necessary to reduce the burden on ophthalmologists and diagnostic contradictions among manual readers.

In this research, convolutional neural network (CNN) was used based on colored retinal fundus images for the detection of DR and classification of its stages. CNN can recognize sophisticated features on the retina and provides an automatic diagnosis. The pre-trained VGG-16 CNN model was applied using a transfer learning (TL) approach to utilize the already learned parameters in the detection.

By conducting different experiments set up with different severity groupings, the achieved results are promising. The best-achieved accuracies for 2-class, 3-class, 4-class and 5-class classifications are 86.5, 80.5, 63.5 and 73.7, respectively.

In this research, VGG-16 was used to detect and classify DR stages using the TL approach. Different combinations of classes were used in the classification of DR severity stages to illustrate the ability of the model to differentiate between the classes and verify the effect of these changes on the performance of the model.

The purpose of this paper is to understand the dynamic and power-laden nature of university–society collaboration from the individual academic's point of view.

This paper applies an autoethnographic approach in following a specific collaboration process through detailed fieldnotes and continuous reflections.

This research presents university–society collaboration as an emergent, volatile and fairly unpredictable process, involving a multitude of actors on both sides. The interactions among actors shape the emerging process and power relationships. The academic's situation could be understood in terms of multiple and shifting subject positions that could be embraced, accepted, resisted or surrendered to by the academic.

These findings may help academics with own experiences of collaboration to shed light on their observations. Novice academics, interested in collaborating with society, should be aware of the possibility of tensions and exercise of power in interactions with societal actors. When setting up collaboration agreements, academic and societal actors are advised to openly discuss potential problems and how to handle those.

This unique, in-depth testimony of a single collaboration process from the individual academic's point of view uncovers previously unobserved dynamic and political attributes of the process.

This paper aims to shed light on the emerging position of companies taking stances on sociopolitical issues and the impact this has on consumers.

The paper uses focus groups, interviews and consumer experiments in various countries, to provide insights as to why brands are taking sociopolitical stances.

Consumers expect brands to take a stance on sociopolitical issues. However, to be credible, a stance needs to be rooted in a long-term commitment that aligns with the brand’s strategy and values. Perceived authenticity is key.

Future studies should aim at broader generalizability and should address various industries.

Differentiating a brand through a sociopolitical stance requires a strategic approach. Brand managers need to identify which issues they should support, how to engage with them and the risks and opportunities involved.

While the impact of brands adopting a sociopolitical stance has been discussed in the mainstream media, there has been a lack of empirical evidence to support the arguments. The results of the four studies discussed in the paper provide insights and demonstrate the brand-related opportunities and risks of taking a sociopolitical stance.

Digital platform users not only consume but also produce communication related to their experiences. Although service research has explored users' motivations to communicate and focused on outcomes such as electronic word-of-mouth (eWOM), it remains largely unexplored how users iteratively interact with communication artifacts and potentially create value for themselves, other users and service providers. The purpose of this paper is, thus, to introduce communicative affordances as a framework to advance user-created communication (UCC) in service.

Drawing from the literature in communication, service research and interactive marketing, an affordance perspective on UCC in service is introduced.

Three UCC affordances for the service context are presented – interactivity, visibility and anonymity – opportunities and challenges for service providers associated with these affordances are discussed and, finally, affordance-specific research questions and general recommendations for future research are offered.

By conceptualizing UCC in service from an affordances perspective, this paper moves beyond the traditional sender–receiver communication framework and emphasizes opportunities and challenges for service research and practice.

Instead of focusing separately on specific technologies or user behaviors, it is recommended that service managers adopt a holistic perspective of user goals and motivations, use experiences and platform design.

By conceptualizing UCC as an augmenting, dialogical process concerning users’ experiences, and by introducing communicative affordances as a framework to advance UCC in service, an in-depth understanding of the diverse and ever-evolving landscape of communication in service is offered.

The purpose of this paper is to explore the perceptions of and barriers to reporting female genital mutilation (FGM) by victims and survivors of FGM to the police in England and Wales.

The paper is based on 14 interviews conducted with adult survivors and victims of FGM. A combination of 1:1 and group interviews were used, based on the preference of the respondents. Respondents were recruited in collaboration with specialist non-governmental organisations and major stakeholders in the area of honour-based violence and black and minority ethnic communities.

A key finding in this research was that all victims/survivors the authors interviewed stated that they did not support the practice of FGM, and that they would not follow it for younger women in their own family. Second, the authors found that none of the respondents had reported their experience to the police. Third, they identified key barriers to reporting, which included: their belief that reporting their own experience would not serve any purpose because they had experienced FGM as children, and in another country; and that they did not feel able to report new incidents of FGM in the community because of a lack of trust in the police due to previous negative experiences. Finally, they believed that FGM could be prevented only by work within the community, and not through engagement with the criminal justice system.

This is, to our knowledge, one of the first papers that is based on victims and survivors’ perceptions that explores barriers to reporting cases of FGM to the police, and offers levers for change.
