Abstract

Purpose

Previous research on narcissism and leadership seldom takes into account the leader–subordinate dyadic relationship and ignores the role of subordinate. Drawing on the contextual reinforcement model of narcissism, the purpose of this study is to explore the joint effects of both leaders’ and their subordinates’ narcissism on the former’s effectiveness through the latter’s perceived relationship conflict with them (RCWL).

Design/methodology/approach

Self-report data were collected from 315 full-time employees using a three-wave survey. Polynomial regression and response surface analysis were used to test the hypotheses.

Findings

The results of this study reveal that although RCWL is higher when leaders’ narcissism is higher along both congruence and incongruence line, RCWL is lower when leaders’ narcissism exceeds that of their subordinates than it falls short of subordinates’ narcissism when both leader’s and subordinate’s narcissism are low. Furthermore, the results of this study also demonstrate that leader–subordinate (in)congruence in narcissism has an indirect influence on the leaders’ effectiveness because of the resulting relationship conflict, and that the response surface of the total effect of joint narcissism on leader effectiveness possesses a convex surface, which demonstrates that leader effectiveness is lower at the median point when compared to the low- and high-level congruence points.

Originality/value

This study not only contributes to fit theory, vertical relational conflict and research on narcissistic leader by simultaneously investigating both leaders’ and subordinates’ narcissism and their joint influence on leader–subordinate relational conflict and leaders’ effectiveness but also offers several practical recommendations for companies to enhance leaders’ effectiveness.

Abstract

Purpose

The purpose of this paper is twofold: first, to identify and rank the challenges influencing the delivery of the housing public-private partnership (HPPP) in Tanzania; and second, to suggest solutions in the form of a conceptual public-private partnership (PPP) framework model that will address the identified challenges and boost the chances of success.

Design/methodology/approach

Using a convergent parallel (concurrent) mixed method approach, data were collected from 28 stakeholders involved with HPPP projects in Tanzania using a hand-delivered and e-mail survey and 13 semi-structured interviews with public and private sector respondents. The quantitative data included subjecting the 19 challenges as identified from the literature to parametric tests such as one-sample t-tests and descriptive statistics tests such as measures of central tendencies and frequency analysis through Statistical Package for Social Sciences (SPSS 22.0). Qualitative data employed content analysis. The research was further underpinned by a number of theoretical perspectives such as Gidden’s structuration theory, contingency theory, relational and equity theory.

Findings

The top five ranked challenges influencing the delivery of HPPP were “inadequate PPP skills and knowledge”; “poor contracting and tendering documents”; “inadequate project management”; “inadequate legal framework”; and “misinformation on financial capacity of private partners”. The least six ranked and most significant challenges based on the one-sample (single) t-tests were as follows: “Poor risk allocation”; “inexperienced private partner”; “unequal qualification and contributions of expertise”; “poor enabling environment to attract competent partners”; “inadequate mechanisms for recovery of private investors’ capital”; and “high costs in procuring PPP projects”. The qualitative study further confirmed the challenges and cited the reason for the failure of joint venture projects as the lack of motivation for undertaking similar PPP projects. Despite the increased awareness of PPP projects and associated marginal benefits, the main impediment to the uptake and delivery of PPP housing projects remained the lack of skills and expertise.

Research limitations/implications

The proposed framework model is not yet tested, but since this paper is part of the ongoing research, the next stage involves the testing and validation of the model. Future studies could test the applicability of the proposed framework in other HPPP projects in Tanzania, and in other similar developing countries. Second, the validated framework can contribute towards addressing similar challenges as well as providing guidance. The proposed framework model is not yet tested, but since this paper is part of the ongoing research, the next stage involves the testing and validation of the model. Furthermore, recommendation for future research is to test the alignment of the identified challenges to the proposed remedial solutions across the five phases within the proposed PPP framework with a number of case studies.

Practical implications

The identified challenges were used to form the basis of the framework presented in this paper. Furthermore, these provide useful information, thus leading to increased awareness to enable successful delivery of HPPP in Tanzania. Similarly, both the government and policy makers could use the findings as the basis for re-examining the existing PPP policy and regulations, and reflecting on the existing situation with a view to improving the delivery of future HPPP projects.

Originality/value

The empirical study is among the first that identifies and ranks the challenges of PPP for housing projects delivery within the Tanzanian context. The identification of the challenges enabled their ranking, resulting in the mapping out of the most critical challenges. Furthermore, using the Gidden’s structuration theory, the study illustrates how institution mechanisms (structures) address these delivery challenges, thus influencing the implementation of HPPP in Tanzania, and how individual stakeholders (human agents or agency) are able to make choices (advocated solutions) in dealing with the challenges. More so, these constraints (challenges) as identified and viewed through the contingency and equity theoretical lenses form the foundation for developing the PPP conceptual framework. The proposed framework would thus serve as a mechanism for providing practical solutions as well as reducing the level of severity of the identified challenges.

Abstract

Purpose

The purpose of this article is to summarise key literature related to the Foundation for Learning and Literacy’s Touchstone 4 (creativity, the arts and imagination).

Design/methodology/approach

This article reviews a selection of relevant studies exploring the contributions of creativity, imagination and the arts to traditional literacy learning. The existing literature has been synthesised and summarised to provide readers with a broad understanding of the evidence supporting Touchstone 4.

Findings

The literature review reveals that all five arts subjects, along with creativity and imagination, contribute positively to students' literacy learning. Each arts subject enhances and extends different aspects of conventional literacy skills – such as reading, writing, viewing, speaking and listening – while fostering the development of multiliteracies.

Originality/value

This article uniquely summarises existing research on the arts, creativity and imagination, highlighting how each area supports literacy development in school students.

Abstract

Purpose

Unconventional machining processes, particularly ultrasonic vibration cutting (UVC), can overcome such technical bottlenecks. However, the precise mechanism through which UVC affects the in-service functional performance of advanced aerospace materials remains obscure. This limits their industrial application and requires a deeper understanding.

Design/methodology/approach

The surface integrity and in-service functional performance of advanced aerospace materials are important guarantees for safety and stability in the aerospace industry. For advanced aerospace materials, which are difficult-to-machine, conventional machining processes cannot meet the requirements of high in-service functional performance owing to rapid tool wear, low processing efficiency and high cutting forces and temperatures in the cutting area during machining.

Findings

To address this literature gap, this study is focused on the quantitative evaluation of the in-service functional performance (fatigue performance, wear resistance and corrosion resistance) of advanced aerospace materials. First, the characteristics and usage background of advanced aerospace materials are elaborated in detail. Second, the improved effect of UVC on in-service functional performance is summarized. We have also explored the unique advantages of UVC during the processing of advanced aerospace materials. Finally, in response to some of the limitations of UVC, future development directions are proposed, including improvements in ultrasound systems, upgrades in ultrasound processing objects and theoretical breakthroughs in in-service functional performance.

Originality/value

This study provides insights into the optimization of machining processes to improve the in-service functional performance of advanced aviation materials, particularly the use of UVC and its unique process advantages.

Abstract

Purpose

Breast cancer is one of the most common malignant tumors in women, which badly have an effect on women's physical and psychological health and even danger to life. Nowadays, mammography is considered as a fundamental criterion for medical practitioners to recognize breast cancer. Though, due to the intricate formation of mammogram images, it is reasonably hard for practitioners to spot breast cancer features.

Design/methodology/approach

Breast cancer is one of the most common malignant tumors in women, which badly have an effect on women's physical and psychological health and even danger to life. Nowadays, mammography is considered as a fundamental criterion for medical practitioners to recognize breast cancer. Though, due to the intricate formation of mammogram images, it is reasonably hard for practitioners to spot breast cancer features.

Findings

The performance analysis was done for both segmentation and classification. From the analysis, the accuracy of the proposed IAP-CSA-based fuzzy was 41.9% improved than the fuzzy classifier, 2.80% improved than PSO, WOA, and CSA, and 2.32% improved than GWO-based fuzzy classifiers. Additionally, the accuracy of the developed IAP-CSA-fuzzy was 9.54% better than NN, 35.8% better than SVM, and 41.9% better than the existing fuzzy classifier. Hence, it is concluded that the implemented breast cancer detection model was efficient in determining the normal, benign and malignant images.

Originality/value

This paper adopts the latest Improved Awareness Probability-based Crow Search Algorithm (IAP-CSA)-based Region growing and fuzzy classifier for enhancing the breast cancer detection of mammogram images, and this is the first work that utilizes this method.

Abstract

Purpose

Health information exchange (HIE) initiatives utilize sharing mechanisms through which health information is mostly transmitted without a patient's close supervision; thus, patient trust in the HIE is the core in this setting. Existing technology acceptance theories mainly consider cognitive beliefs resulting in adoption behavior. The study argues that existing theories should be expanded to cover not only cognitive beliefs but also the emotion provoked by the sharing nature of the technology. Based on the theory of reasoned action, the technology adoption literature, and the trust literature, we theoretically explain and empirically test the impact of perceived transparency of privacy policy on cognitive trust and emotional trust in HIEs. Moreover, the study analyzes the effects of cognitive trust and emotional trust on the intention to opt in to HIEs and willingness to disclose health information.

Design/methodology/approach

An online survey was conducted using data from individuals who were aware of HIEs through experience with at least one provider participating in an HIE network. Data were collected from a wide range of adult population groups in the United States.

Findings

The structural equation modeling analysis results provide empirical support for the proposed model. The model highlights the strategic role of the perceived transparency of the privacy policy in building trust in HIEs. When patients know more about HIE security measures, sharing procedures, and privacy terms, they feel more in control, more assured, and less at risk. The results also show that patient trust in HIEs may take the forms of intention to opt in to an HIE and willingness to disclose health information exchanged through HIE networks.

Originality/value

The findings of this study should be of interest to both academics and practitioners. The research highlights the importance of developing and using a transparent privacy policy in the diffusion of HIEs. The findings provide a deep understanding of dimensions of HIE privacy policy that should be addressed by health-care organizations to exchange personal health information in a secure and private manner.

Abstract

Purpose

This paper proposes a Web-based patient portal based on the electronic medical record. Such a portal can allow patients to manage their own health care, reduce health-care visits and significantly improve the quality of their health care.

Design/methodology/approach

A patient portal prototype and an accompanying online survey were distributed to assess the adoption readiness among a group of people in the United Arab Emirates (UAE).

Findings

The results from 470 survey participants demonstrated an enhanced awareness of this technology, and support the study hypotheses indicating that both intrinsic and extrinsic factors are important when considering the implementation of a patient portal in the UAE.

Originality/value

This study adds value to the few research studies undertaken in the Middle East discussing online health information technology and its adoption and usage among the population at large. The extended technology acceptance model, which contains two additional constructs, had not been previously validated in terms of a patient portal in the UAE, according to the author’s knowledge, adding more value. The UAE’s health-care system must use the benefits from the available IT infrastructure to provide a user-friendly online portal to encourage patients to manage their health care and health information.

Abstract

Purpose

Patient-centric exchanges, a major type of Health Information Exchange (HIE), empower patients to aggregate and manage their health information. This exchange model helps patients access, modify and share their medical information with multiple healthcare organizations. Although existing studies examine patient engagement, more research is required to investigate patients' attitudes and willingness to play an active role in patient-centered information exchange. The study's main objective is to develop a model based on the belief-attitude-intention paradigm to empirically examine the effects of patients' attitudes toward engagement in care on their willingness to participate in patient-centric HIE.

Design/methodology/approach

The authors conducted an online survey study to identify the antecedents and consequences of patients' attitudes toward engagement in care. To empirically test the research model, the authors collected data from a national sample (n = 357) of individuals in the United States. The data were analyzed using structural equation modeling (SEM).

Findings

The proposed model categorizes the antecedents to patients' attitudes toward engagement in patient-related and healthcare system factors. The results show that patient-related factors (perceived health literacy and perceived coping ability) and health system factors (perceived experience with the healthcare organization and perceived patient-provider interaction) significantly shape patient attitude toward care management engagement. The results indicate that patients' attitudes toward engaging in their healthcare significantly contribute to their willingness to participate in medical information sharing through patient-centric HIE initiatives. Moreover, the authors’ findings also demonstrate that the link between patient engagement and willingness to participate in HIE is stronger for individuals who perceive lower levels of privacy and security concerns.

Originality/value

The authors validate the proposed model explaining patients' perceptions about their characteristics and the healthcare system significantly influence their attitude toward engaging in their care. This study also suggests that patients' favorable attitude toward engagement can bring patient-centric HIE efforts onto a path to success. The authors’ research attempts to shed light on the importance of patients' roles in adopting patient-centric HIE initiatives. Theoretical and practical contributions of this study are noticeable since they could result in a deeper understanding of the concept of patient engagement and how it may affect healthcare services in an evolving digital world. The authors’ findings can help healthcare organizations provide public citizen-centric services by introducing user-oriented approaches in healthcare delivery systems.
