Purpose This paper aims to gauge developers’ perspectives regarding the participation of the public and anonymous crowd testers worldwide, with a range of varied experiences. It also aims to gather their needs that could reduce their concerns of dealing with the public crowd testers and increase the opportunity of using the crowdtesting platforms. Design/methodology/approach An online exploratory survey was conducted to gather information from the participants, which included 50 mobile application developers from various countries with diverse experiences across Android and iOS mobile platforms. Findings The findings revealed that a significant proportion (90%) of developers is potentially willing to perform testing via the public crowd testers worldwide. This on condition that several fundamental features were available, which enable them to achieve more realistic tests without artificial environments on large numbers of devices. The results also demonstrated that a group of developers does not consider testing as a serious job that they have to pay for, which can affect the gig-economy and global market. Originality/value This paper provides new insights for future research in the study of how acceptable it is to work with public and anonymous crowd workers, with varying levels of experience, to perform tasks in different domains and not only in software testing. In addition, it will assist individual or small development teams who have limited resources or who do not have thousands of testers in their private testing community, to perform large-scale testing of their products.

Purpose – The purpose of this paper is to describe a model of digital library (DL) work that surfaced through the ARL Profiles 2010 and resonates current work underway by the large-scale DL projects like DPLA, SHARE, Hathitrust, Academic Preservation Trust, and Digital Preservation Network. Design/methodology/approach – In total, 86 ARL members submitted institutional profiles that were analyzed using Atlas.ti and surfaced major themes that comprise the mission of research libraries including serving the public good, expanding their presence globally, setting standards for access and quality, needing to explore best practices, and being visible at the national and international levels. Findings – The analysis of the narratives identified three key areas for DL developments: first, digitized special collections, second, acquiring digital content, and third, developing digital services (Figure 1). Specific examples and context are provided in the paper. Research limitations/implications – The qualitative data collected from these profiles demonstrate that libraries are transforming their services to leverage digital technologies and meet the changing needs of their users. The approach was open ended and allowed libraries to celebrate their strengths and unique context. Some of the disadvantages of this approach include the amount of work both on behalf of the participating libraries as well as on behalf of the analysts and the difficulty of comparing libraries with one another. Originality/value – This was the first time ARL attempted to describe research libraries using narrative descriptions. The approach complements the traditional ARL Statistics and offers a viable alternative in a future environment that is dominated by radical change. This qualitative approach deployed here is critical for describing DL developments as current large-scale digitization projects have extended the directions that were surfacing in these profiles and have major implications for the future of digital content and research. Future research in this area is strongly encouraged.

Purpose The purpose of this paper is to benchmark the operational and financial performances of the major Indian seaports to help derive useful insights to improve their performance. Design/methodology/approach A two-stage data envelopment analysis (DEA) methodology has been used with the help of data collected on the 13 major seaports of India. The first stage of the DEA captured the operational efficiencies, while the second stage the financial performance. Findings A window analysis over a period of three years revealed that no port was able to score an overall average efficiency of 100 per cent. The study identified the better performing units among their peers in both the stages. The contrasting results of the study with the traditional operational and financial performance measures used by the ports helped to derive useful insights. Research limitations/implications The data used in the study were majorly limited to the available sources in the public domain. Also, the study was limited to the major seaports which are under the Government of India and no comparisons were carried out with other local or international ports. Practical implications There is a need to prioritize investments and improvement efforts where they are most needed, instead of following a generalized approach. Once the benchmark ports are identified, the port authorities and other relevant stakeholders should work in detail on the factors causing inefficiencies, for possible improvements in performance. Originality/value This paper carried out a two-stage DEA that helped to derive useful insights on operational efficiency and financial performance of the India seaports. A combination of the financial and operational parameters, along with a comparison of the DEA results with the traditional measures, provided a different perspective on the Indian seaport performance. Considering the scarcity of research papers reported in the literature on DEA-based benchmarking studies of seaports in the Indian context, it has the potential to attract future research in this field.

Abstract Anterior segment eye diseases account for a significant proportion of presentations to eye clinics worldwide, including diseases associated with corneal pathologies, anterior chamber abnormalities (e.g. blood or inflammation) and lens diseases. The construction of an automatic tool for the segmentation of anterior segment eye lesions will greatly improve the efficiency of clinical care. With research on artificial intelligence progressing in recent years, deep learning models have shown their superiority in image classification and segmentation. The training and evaluation of deep learning models should be based on a large amount of data annotated with expertise, however, such data are relatively scarce in the domain of medicine. Herein, the authors developed a new medical image annotation system, called EyeHealer. It is a large-scale anterior eye segment dataset with both eye structures and lesions annotated at the pixel level. Comprehensive experiments were conducted to verify its performance in disease classification and eye lesion segmentation. The results showed that semantic segmentation models outperformed medical segmentation models. This paper describes the establishment of the system for automated classification and segmentation tasks. The dataset will be made publicly available to encourage future research in this area.

Purpose The purpose of this paper is to offer a review of the selected literature in ethical leadership synthesizing findings from 45 articles selected from journals on leadership, public administration, organizational behavior, psychology and ethics. Design/methodology/approach Four themes are addressed: the conceptualization of ethical leadership theories, the existence of popular measurement instruments for ethical leadership, findings on ethical leadership in the public sector and outcomes of ethical leadership in terms of benefits and negative consequences. Findings The definition by Brown et al. (2005) is the most frequently used definition, even though recent criticism states that this definition may be too narrow. Ethical leadership is usually measured by means of a survey; however, there are at least three different questionnaires in use. In the public sector, ethical leadership has been linked to both positive outcomes and negative consequences. Research limitations/implications This paper only includes selected academic articles and does not include published books. Originality/value Based on our findings, the authors present recommendations for future research, among others into a broader conceptualization of ethical leadership and the use of mixed methods.

Purpose – There are many different conceptualizations to sustainable development and these different approaches may have led to confusion amongst the public. The purpose of this paper is to explore the identities of the term and how the confused identity may be leading to problems for sustainable development efforts. Design/methodology/approach – The design is exploratory, using both secondary and primary data to understand the different sustainable development concepts. Findings – There is no consistent understanding or use of the term “sustainable development” among various groups. Research limitations/implications – Future research should include a larger sample that is more representative of people from different backgrounds and geographical areas. Practical implications – The public is generally willing to support only projects that it understands. Without a clear understanding of sustainable development, the public will be less inclined to support these efforts. Originality/value – This study examines the perceptions and understandings of the term by the general public representing different generations.

Purpose The aim of this paper is to characterize how innovation may happen through cross-functional teams (CFT) in an organization of the public sector. Design/methodology/approach A case study helped to characterize several behavior patterns, team structures and respective links with generating innovation in internal processes and public answering contexts. Findings The results highlight that formal-temporary teams present a higher capacity to generate incremental innovation in products, whereas permanent-informal teams have a higher capacity to generate innovation in the internal processes and public answering contexts. Research limitations/implications The limitations of this research relate to the fact that this is a single case study, and although it is an important case to examine innovation and CFTs, by its very nature, it is not possible to extend and generalize the obtained data to other organizations. The evaluation of its propositions was merely qualitative, and future research is needed to validate its characteristics. Practical implications Several settings of CFTs are presented, as well as their ability to generate different types of innovation, such as the computerization of documents, petitions and papers, which decreases the time to answer the taxpayer. Moreover, CFTs can help to create products, such as computer programs that can be used not only locally but also in several public organizations related to tax management. Originality/value The field research provides the perceptions of the respondents regarding CFT characteristics that can lead to specific types of innovation, as well as the types of products or services that can be generated by these processes.

Purpose Brand “Likes” on Facebook facilitate self-expression, forming part of consumers’ virtual selves. Yet, consumers’ brand “Likes” may bear little resemblance to their material realities. This paper aims to test similarities of brand image with self-image for Facebook “Likes” to determine whether self-congruence with a “Liked” brand leads to positive offline brand outcomes. It also investigates whether consumers’ perceptions about their Facebook social relations influence self-congruent brand “Likes”. Design/methodology/approach A large-scale survey was conducted of regular Facebook users who “Liked” brands. Data from 438 respondents was analysed and hypotheses tested using structural equation modeling. Findings Empirical results show that the perceived self-congruence with a “Liked” brand increases with social tie strength. Perceived social tie strength is informed by perceived attitude homophily. When the perceived self-congruence with a “Liked” brand is higher, brand love and word of mouth (WOM) are enhanced. Consumers also have greater brand loyalty and offer more WOM when brands are loved. Research limitations/implications Findings demonstrate the influence of consumers’ cognitive network on “Likes” and brand outcomes. Further replication would enhance generalisability. Future research should use a wider sample and investigate other variables. Practical implications Findings support managers seeking to grow and analyse Facebook “Likes” by providing insights into brand loyalty, brand love and WOM for “Liked” brands. Originality/value The paper addresses the dearth of research exploring how consumers’ perceptions of their Facebook network influence their online brand behaviour and how perceived self-congruence with a “Liked” brand relates to brand outcomes.

PurposeThis paper presents a systematic literature review aiming at analysing how research has addressed performance measurement systems’ (PMSs) ambiguities in the public sector. This paper embraces the ambiguity perspective that PMSs in public sector coexist with and cope with existing ambiguities.Design/methodology/approachThe authors conducted a literature review in Scopus and ScienceDirect, considering articles published since 1985, and the authors selected articles published in the journals included in the Association of Business Schools' Academic Journal Guide (Chartered ABS, 2018). Of the 1,278 abstracts that matched the study’s search criteria, the authors selected 131 articles for full reading and 37 articles for the final discussion.FindingsThe study's key findings concern the elements of ambiguity in PMSs discussed in the literature. The study’s results suggest that ambiguity is still a relevant problem in performance measurement, as a problem that is impossible to be solved and therefore needs to be better understood by researchers and public managers. The analysis allows us to summarize the antecedents and consequences of ambiguity in the public sector.Research limitations/implicationsThe key findings of the study concern the main sources of ambiguity in PMSs discussed in the literature, their antecedents and their consequences. The study results suggest that ambiguity exists in performance measurement and that is an issue to be handled with various strategies that can be implemented by managers and employees.Practical implicationsManagers and researchers may benefit from this research as it may represent a guideline to understand ambiguities in their organizations or in field research. Researchers may also benefit from a summary list of the key issues that have been analysed in the empirical cases provided by this research. Social implicationsThis research may provide insights to limit ambiguity and thus contribute to improve performance measurement in the public sector.Originality/valueThis research presents a comprehensive review on the topic. It provides insight that suggests what future research should attend to in helping to interpret ambiguity, considering also what should be done to influence ambiguity.

PurposeThis paper examines the empirical research on police reassurance following a collective trauma event (CTE).Design/methodology/approachUsing a scoping review methodology, this paper sought to establish the extent, range and nature of published literature on policing responses to collective traumatic events, and to identify key features of this form of direct practice. Included papers needed to focus on police responses oeassurance with the public related to events (pre-or post) that could be regarded as collective trauma events by nature or scale. Searches were conducted using the Web of Science, SCOPUS and PsychINFO databases for literature published between January 2000 and December 2019.FindingsFourteen articles met the inclusion criteria. The key themes identified: (1) measuring the impact of reassurance and community policing; (2) community attitudes to policing and social disorder/critical events; (3) police workforce responses to traumatic events; and (4) interventions to support police to respond to their community.Research limitations/implicationsFuture research needs to examine the elements that create a robust organisational infrastructure that can withstand the demands of policing in ordinary and extraordinary times. Fundamental to the studies in this review is the relationship between the police agencies and the community. The nature of this relationship and how it can be strengthened to ameliorate the negative impact of CTEs in communities needs further exploration.Originality/valueThis paper provides important findings that can inform future reassurance policing practice and research.

Purpose In providing a fine-grained analysis of public service management, the purpose of this paper is to make an important contribution to furthering research in service management, a body of literature that has tended to regard public services as homogenous or to neglect the context altogether. Design/methodology/approach Integrating public management and service management literatures, the past and present of public service management are discussed. Future directions for the field are outlined drawing on a service-dominant approach that has the potential to transform public services. Invited commentaries augment the review. Findings The review presents the Public Service Network Framework to capture the public value network in its abstraction and conceptualizes how value is created in public services. The study identifies current shortcomings in the field and offers a series of directions for future research where service management theory can contribute greatly. Research limitations/implications The review encourages service management research to examine the dynamic, diverse, and complex nature of public services and to recognize the importance of this context. The review calls for an interdisciplinary public service management community to develop, and to assist public managers in leveraging service logic. Originality/value The review positions service research in the public sector, makes explicit the role of complex networks in value creation, argues for wider engagement with public service management, and offers future research directions to advance public service management research.
