Purpose Image annotation plays an important role in image retrieval process, especially when it comes to content-based image retrieval. In order to compensate the intrinsic weakness of machines in performing cognitive task of (human-like) image annotation, leveraging humans’ knowledge and abilities in the form of crowdsourcing-based annotation have gained momentum. Among various approaches for this purpose, an innovative one is integrating the annotation process into the CAPTCHA workflow. In this paper, the current state of the research works in the field and experimental efficiency analysis of this approach are investigated.Design/methodology/approach At first, and with the aim of presenting a current state report of research studies in the field, a comprehensive literature review is provided. Then, several experiments and statistical analyses are conducted to investigate how CAPTCHA-based image annotation is reliable, accurate and efficient.Findings In addition to study of current trends and best practices for CAPTCHA-based image annotation, the experimental results demonstrated that despite some intrinsic limitations on leveraging the CAPTCHA as a crowdsourcing platform, when the challenge, i.e. annotation task, is selected and designed appropriately, the efficiency of CAPTCHA-based image annotation can outperform traditional approaches. Nonetheless, there are several design considerations that should be taken into account when the CAPTCHA is used as an image annotation platform.Originality/value To the best of the authors’ knowledge, this is the first study to analyze different aspects of the titular topic through exploration of the literature and experimental investigation. Therefore, it is anticipated that the outcomes of this study can draw a roadmap for not only CAPTCHA-based image annotation but also CAPTCHA-mediated crowdsourcing and even image annotation.

Purpose Although there has been an increase in workplace studies on professional agency, few of these have examined the role of emotions in the enactment of agency at work. To date, professional agency has been mainly conceptualised as a goal-oriented, rational activity aimed at influencing a current state of affairs. Challenged by this, this study aims to elaborate the nature and quality of emotions and how they might be connected to the enactment of professional agency. Design/methodology/approach Data are collected in the context of a leadership coaching programme that aimed to promote the leaders’ professional agency over the course of a year. The participants (11 middle-management leaders working in university and hospital contexts) were interviewed before and after the programme, and the data were analysed using qualitative content analysis. Findings Findings showed that emotions played an important role in the leaders’ enactment of professional agency, as it pertained to their work and to their professional identity. The study suggests that enacting professional agency is by no means a matter of purely rational actions. Practical implications The study suggests that emotional agency can be learned and enhanced through group-based interventions reflecting on and processing one’s own professional roles and work. Originality/value As a theoretical conclusion, the study argues that professional agency should be reconceptualised in such a way as to acknowledge the importance of emotions (one’s own and those of one’s fellow workers) in practising agency within organisational contexts.

Purpose This study aims to focus on creating sales capability as part of new product development (NPD). The aim is to define generic requirements for building sales capability as a part of NPD and to propose a necessary process by defining key activities for sales readiness. Design/methodology/approach An inductive and qualitative research method was used to construct a sales capability creation process based on a current state analysis in seven companies. Findings The results indicate that the status of companies’ sales-related planning varies during the NPD, and the related activities are not systematically managed. Considering sales early is necessary to enable a smooth and cost-efficient start of sales, and to avoid unnecessary delays and problems in other functions. At the same time, the companies recognise the need for improvement. Originality/value This paper presents a potential process including systematic activities for creating sales capability in conjunction with product development, which is novel to the literature. The proposed process is applicable in aligning industrial company needs.

Administrators of programs for children with communicative disorders in 11 midwestern states were surveyed to assess trends in the training and utilization of paraprofessionals. Topics included: (a) current trends in employment, (b) paraprofessional training, (c) use of ASHA and state guidelines, and (d) district policies for supervision. Selection criteria, use of job descriptions, training programs, and supervision practices and policies were examined. Results indicate that paraprofessionals are used but that standards for training and supervision are not consistently applied across all programs. Program administrators report minimal training for supervising professionals.

 There is scant research-based evidence on the development and adoption of open access (OA) and institutional repositories (IRs) in Africa, and in Kenya in particular. This article reports on a study that attempted to fill that gap and provide feedback on the various OA projects and advocacy work currently underway in universities and research institutions in Kenya and in other developing countries. The article presents the findings of a descriptive study that set out to evaluate the current state of IRs in Kenya. Webometric approaches and interviews with IR managers were used to collect the data for the study. The findings showed that Kenya has made some progress in adopting OA with a total of 12 IRs currently listed in the Directory of Open Access Repositories (OpenDOAR) and five mandatory self-archiving policies listed in the Registry of Open Access Repositories Mandatory Archiving Policies (ROARMAP). Most of the IRs are owned by universities where theses and dissertations constitute the majority of the content type followed by journal articles. The results on the usage and impact of materials deposited in Kenyan IRs indicated that the most viewed publications in the repositories also received citations in Google Scholar, thereby signifying their impact and importance. The results also showed that there was a considerable interest in Swahili language publications among users of the repositories in Kenya.

Physician Stress

Purpose Physician stress and burnout is a serious and common concern in healthcare, with over half of physicians in the USA meeting at least one criterion for burnout. The paper aims to discuss these issues. Design/methodology/approach A review on current state of physician stress and burnout research, from 2008 to 2016, was undertaken. A subsequent perspective paper was shaped around these reviews. Findings Findings reveal research strength in prevalence and incidence with opportunities for stronger intervention studies. While descriptive studies on causes and consequences of physician burnout are available, studies on interventions and prevention of physician burnout are lacking. Future research on physician stress and burnout should incorporate intervention studies and take care to avoid limitations found in current research. Accountability and prevention of physician burnout is the responsibility of the healthcare industry as a whole, and organizational strategies must be emphasized in future research. Originality/value The value of this research comes in the original comprehensive review, international inclusion and succinct summary of physician burnout research and strategies.

SummaryThe conventional belief since the publication of the Black Report is that social inequalities in health have been increasing since 1931–32 although it has been argued that the measure of inequality used is inappropriate. All analyses have been based on mortality rates which, in large part, reflect inequalities in health over the previous 50 years and not current trends. This paper argues that time trends should be assessed with a current health status measure and suggests using height at age 20 as a good measure of the achieved health status of a group. Analysis of a government survey shows that inequalities have stayed the same since 1940, both for men classified by their own occupation and for women classified by their father's occupation.

Purpose The purpose of paper is twofold. First, it provides a consolidated overview of the existing literature on “big data” and second, it presents the current trends and opens up various future directions for researchers who wish to explore and contribute in this rapidly evolving field. Design/methodology/approach To achieve the objective of this study, the bibliographic and network techniques of citation and co-citation analysis was adopted. This analysis involved an assessment of 57 articles published over a period of five years (2011-2015) in ten selected journals. Findings The findings reveal that the number of articles devoted to the study of “big data” has increased rapidly in recent years. Moreover, the study identifies some of the most influential articles of this area. Finally, the paper highlights the new trends and discusses the challenges associated with big data. Research limitations/implications This study focusses only on big data concepts, trends, and challenges and excludes research on its analytics. Thus, researchers may explore and extend this area of research. Originality/value To the knowledge of the authors, this is the first study to review the literature on big data by using citation and co-citation analysis.

Object. Despite a long and controversial history, psychosurgery has persisted as a modern treatment option for some severe, medically intractable psychiatric disorders. The goal of this study was to review the current state of psychosurgery. Methods. In this review, the definition of psychosurgery, patient selection criteria, and anatomical and physiological rationales for cingulotomy, subcaudate tractotomy, anterior capsulotomy, and limbic leukotomy are discussed. The historical developments, modern procedures, and results of these four contemporary psychosurgical procedures are also reviewed. Examples of recent advances in neuroscience indicating a future role for neurosurgical intervention for psychiatric disease are also mentioned. Conclusions. A thorough understanding of contemporary psychosurgery will help neurosurgeons and other physicians face the ethical, social, and technical challenges that are sure to lie ahead as modern science continues to unlock the secrets of the mind and brain.
