PurposeSocial media have become famous platform to search and share the COVID-19-related information. The objective of this research is to bridge the gap by proposing the effects of network cluster and transmitter activity on information sharing process.Design/methodology/approachData were collected by using Facebook application, which was available for 14 days (May 1–14) in 2020. These data were analyzed to determine the influence of the network cluster and transmitter activity.FindingsThe results showed that network cluster is positively related to transmitter activity on social media. In addition, transmitter activity partially mediated the effect of network cluster on the extent of information liked and shared. That is, transmitter activity can affect COVID-19-related information sharing on Facebook, and the activity effect is plausible and should become stronger as social network become denser.Originality/valueThis study has contributed to the knowledge of health information sharing in social media and has generated new opportunities for research into the role of network cluster. As social media is firmly entrenched in society, researches that improve the experience or quality for users is potentially impactful.

Information sharing (IS) is a key capability required for one-stop and networked government, responding to a variety of intra-organizational, inter-organizational, or cross-national needs like sharing service-related information between parties involved in the delivery of seamless services, sharing information on available resources to enable whole-of-government response to emergencies, etc. Despite its importance, the IS capability is not common for governments due to various technical, organizational, cultural, and other barriers which are generally difficult to address by individual agencies. However, developing such capabilities is a challenging task which requires government-wide coordination, explicit policies and strategies, and concrete implementation frameworks. At the same time, reconciling existing theoretical frameworks with the IS practice can be difficult due to the differences in conceptions and abstraction levels. In order to address such difficulties, this chapter proposes a conceptual framework to guide the development of Government Information Sharing (GIS) policies, strategies, and implementations. By integrating theoretical frameworks and the GIS practice, the framework adopts a holistic view on the GIS problem, highlights the main areas for policy intervention, and provides policy makers and government managers with conceptual clarity on the GIS problem.

Purpose – This paper aims to empirically explore demand-related information sharing in the extended supply chain. Design/methodology/approach – Through a single, embedded case design, a range of methods are used to collect data from companies representing three different supply chain tiers, including focal company, first-tier suppliers and first-tier customers. The collected data are analysed through the theoretical lens of interdependence. Findings – The findings indicate that the supply chain actors adapt information sharing to the pooled, serial or reciprocal type of interdependence. Information sharing is thus increased with key dyadic partners representing, for example, unique offerings and high market shares as percentage of total expenditure/sales. The study also unearths several barriers to information sharing beyond dyadic ties, including problems related to dis-aggregated, misinterpreted and/or incomplete information. Research limitations/implications – The study empirically contributes to the existing literature by exploring information sharing in the extended supply chain and by suggesting different approaches to information sharing depending on the type and intensity of interdependence between supply chain partners. Further, the paper contributes to the existing literature on barriers of information sharing in supply chains by identifying barriers specific to multi-tier information sharing. “Meta-information” (i.e. information about the shared information) is needed to overcome some of the barriers of sharing information in cases of weak, pooled interdependencies in the supply chain. Practical implications – Similar to previous empirical research, this exploratory study indicates that companies, in general, refrain from sharing information beyond dyadic ties. Supply chain managers would instead mostly focus on stronger, reciprocal interdependencies and emphasise dyadic information sharing. To further guide managers, a demand profiling framework considering market share and demand uncertainty is presented. It may be interesting to engage in multi-tier information sharing in particular cases where strong interdependence exists between three or more partners. Originality/value – This study contributes to existing research on information sharing in supply chains by empirically studying information sharing in an extended supply chain, applying interdependence theory as its analytical framework and unearthing several barriers that are specific to multi-tier information sharing.

Breast cancer is one of the most prevalent malignancies in women worldwide and affects all dimensions of health. The aim of this meta-aggregative review is to describe the experience of diagnosis and the subsequent period of therapy of women with breast cancer. Following a systematic literature research, ten publications were included in the meta-aggregative review and the study results were synthesized by categorization. Emotional burden, challenges, psychosocial support, and individual coping strategies were described by affected women, and disease-related information sharing and fulfilment of expectations in health professionals were experienced as unsatisfactory. There is a need for improvement in the context of information and counseling measures by health professionals.

Under Uganda’s decentralised system, rural water service delivery remains to some extent problematic. Several studies attribute the possible causes of deficiencies in the water sector to governance issues. This article applies social network analysis to map upward and downward water-related information flows between the actors of local government from village to district level. Comparing the actual information-sharing network with what’s on paper reveals a less reciprocal and more centralised network than that theoretically envisaged. Some actors, such as the district water officer, are more central than expected in terms of sending and receiving information, while others seem to underperform. Our findings show, however, that it is not the political–administrative information exchange which is the biggest obstacle, but rather information flows between higher (district and sub-county) and lower (parish and village) levels of the local governance structure. Adding water users to the analysis reveals the village chairperson as the most crucial broker of information upward to duty bearers at district level. The limited role of water user committees also becomes apparent. The authors conclude that information communication technology holds potential to overcome some of the bottlenecks (eg distance) hindering the flow of water-related information between actors at different levels.

COVID-19 is a disease caused by a novel coronavirus originated in Wuhan, China. The virus rapidly spread over more than 200 countries around the world and caused deaths of more than 690.000 of people. To prevent rapid spreading of this disease, the information sharing related to the findings about the COVID-19 disease must be fast and secure between countries. Since the COVID-19 related health data such as the symptoms and private patient records are confidential, such information requires privacy protection. The blockchain and smart contracts are well-suited solutions for speed, privacy, and security needs of dissemination the COVID-19 related information. Blockchain based e-health solutions have been discussed for years. However, a pandemic is more important than the regular health problems. Thus, this study proposes how critical pandemic related information should be shared between the participating countries and can be accessed by health data actors such as researchers, doctors, laboratory staff, authorized institutions of different countries as well as the World Health Organization.

The use of internet and social media for health information sharing is expanding among public, pharmacists and other healthcare professionals over the past few years. Research investigating the use of internet and social media in the practice of pharmacy is growing, however, little is known on the delivery of pharmacy services through these media platforms. Hence, this study aimed to investigate the roles of pharmacist in media in providing healthcare information, to evaluate public perception and acceptance towards pharmacist using media as a platform information sharing and to find out public expectation towards pharmacy services in media. A total of 200 respondents were involved by random sampling in this cross-sectional study. Study duration was from October until November 2019. The self-administered questionnaire was adapted from previous study investigating the public preferred source of healthcare advices. Majority of the respondents agree that media platforms can be used by pharmacist to improve patient-pharmacist communication with 76.5% expected that social media has the potential to become an established channel for patient-pharmacist communication. 61.0% of the respondents also acknowledged pharmacist to be very knowledgeable on health-related information by providing accurate information. This study provided insights into the public view towards the roles of pharmacist and their expectation towards pharmacist sharing health-related information in media platforms. Participants recognized the potential use of media platforms for healthcare information sharing. To enhance pharmacist presence and impact on public health through digital media platforms, it is important to start incorporating digital medium into their pharmacy services.
