The purpose of this paper is to outline the organization and governance of the US vaccine and immunization enterprise. It describes the major components of the US system including the various relationships between major federal government entities, stakeholders, and advisory committees that inform government policymaking at various points in the system.

The authors describe the complex interdependent network of partners that engage in a wide range of activities such as disease surveillance, research, vaccine development, regulatory licensure, practice recommendations, financing, service delivery, communications, and post-licensure monitoring.

The US system of governance is highly participatory and focuses on a transparent and open engagement, with input from a wide range of partners to inform decision-making. This collaborative framework allows many inputs to be heard and helps support the US vaccine and immunization system as it evolves to meet the continued public health needs in the USA through the optimal use of safe and effective vaccines.

This is an invited article on the US vaccine and immunization enterprise. The development and availability of vaccines in the USA has had profound impact on mortality and morbidity and public health (Centers for Disease Control and Prevention, 2011). The success of this enterprise is a result of a blended public and private sector system with partnerships at the federal, state, and local levels of government to optimize the use of safe and effective vaccines. Governance structures have been established to support the interaction and decision-making among the federal and non-federal actors toward the common goal of controlling and preventing infectious diseases.

Focusing on female entrepreneurs operating in a resource-scarce environment, this study aims to draw from the resource-based view to examine the relationship between entrepreneurial competences and firm growth.

This study used a cross-sectional research design. Data was collected from 232 women entrepreneurs operating in Kampala’s two biggest markets. The data were analyzed to test the mediation effect of absorptive capacity on the relationship between entrepreneurial competences and firm growth; a Sobel test and bootstrap estimation were analytical approaches that were used.

This paper argues that for female entrepreneurs, the venture growth process is not simply dependent on inimitable resources such as competences, as these are first not readily available to female entrepreneurs and second, only provide a temporary competitive advantage. Rather, venture growth also involves the ability to continuously identify and exploit knowledge resources through an absorptive capacity that may be limited by the sociocultural context within which the female entrepreneur operates in sub-Saharan Africa.

The novelty of this research resides in support for the mediating role of the ability to recognize the value of new information, assimilate it and apply it to commercial ends. This study shows that female entrepreneurs use externally generated knowledge as a mechanism to grow their firms and this is impacted by the sociocultural context within which they operate. The study further improves the understanding of the resource-based view by suggesting that a black box exists in the relationship between resources and performance. It is shown that the possession of one resource facilitates the acquisition of other resources and proposes that the role of resources continuously unfolds as a firm develops.

We advance entrepreneurship research by developing a theoretical model of how founding teams form. Our neo-Carnegie model situates nascent founders in particular network-structural milieus, engaging in aspiration-driven search for and evaluation of prospective co-founders. The formation of co-founding ties between nascent founders can be divided into four theoretical steps, which we label activation, evaluation, approach, and reciprocation. Successful founding team formation is a consequence of mutually favorable evaluations by nascent founders in a multi-sided matching process. Nascent founders with higher and less flexible aspirations are more likely to undertake distant search for co-founders by seeking referrals, forming ties with strangers, and forming new ties to social foci where they might meet potential co-founders. Churn in newly formed founding teams emerges as a consequence of shifting dominant coalition dynamics in the founding team caused by organic venture evolution and intentional changes in strategic direction. Our theoretical model provides new insights on the formation pathways of founding teams, their initial task and relational resource endowments, and initial team dynamics.

This study investigates the effects of using social media for customer service on firms' reputation building. In addition, this study explores the role of absorptive capacity, ISO (International Organization for Standardization) 9,000 implementation and periodic training for management and employees in the relationship between social media–based customer service and firm reputation.

This study sampled 115 US-listed firms and collected secondary data from five databases as follows: Factiva, Fortune's World's Most Admired Companies (WMAC), Standard & Poor's COMPUSTAT, American Customer Satisfaction Index (ACSI) and Thomson Reuters’ Environmental, Social and Governance (ESG). This study developed a panel dataset of these 115 firms from 2007 to 2016 and conducted dynamic panel data analyses to examine the hypotheses.

This study finds that a higher number of social media channels used for customer service is associated with a higher reputation score for a firm. In addition, the positive relationship is reinforced when a firm has a high absorptive capacity level, an ISO 9000 quality management system and offers periodic training for management and employees.

To the best of our knowledge, this is the first study to investigate the relationship between social media–based customer service and firm reputation. This study also explores the boundary factors in terms of firm absorptive capacity, ISO 9000 quality management systems and training for management and employees.

Social annotation (SA) is a genre of learning technology that enables the annotation of digital resources for information sharing, social interaction and knowledge production. This study aims to examine the perceived value of SA as contributing to learning in multiple undergraduate courses.

In total, 59 students in 3 upper-level undergraduate courses at a Canadian university participated in SA-enabled learning activities during the winter 2019 semester. A survey was administered to measure how SA contributed to students’ perceptions of learning and sense of community.

A majority of students reported that SA supported their learning despite differences in course subject, how SA was incorporated and encouraged and how widely SA was used during course activities. While findings of the perceived value of SA as contributing to the course community were mixed, students reported that peer annotations aided comprehension of course content, confirmation of ideas and engagement with diverse perspectives.

Studies about the relationships among SA, learning and student perception should continue to engage learners from multiple courses and from multiple disciplines, with indicators of perception measured using reliable instrumentation.

Researchers and faculty should carefully consider how the technical, instructional and social aspects of SA may be used to enable course-specific, personal and peer-supported learning.

This study found a greater variance in how undergraduate students perceived SA as contributing to the course community. Most students also perceived their own and peer annotations as productively contributing to learning. This study offers a more complete view of social factors that affect how SA is perceived by undergraduate students.

The privacy calculus based on a single stakeholder failed to explain users' co-owned information disclosure owing to the uniqueness of co-owned information. Drawing on collective privacy calculus theory and impression management theory, this study attempts to explore the co-owned information disclosure of social network platform users from a collective perspective rather than an individual perspective.

Drawing on collective privacy calculus theory and impression management theory, this study explores the co-owned information disclosure of social network platform users from a collective perspective rather than an individual perspective based on a survey of 740 respondents.

This study finds that self-presentation and others presentation directly positively affect users' co-owned information disclosure. Also, self-presentation, others presentation and relationship presentation indirectly positively affect users' co-owned information disclosure via relationship support. Furthermore, personal privacy concern, others' privacy concern and relationship privacy concern indirectly negatively affect users' co-owned information disclosure via relationship risk.

The findings develop the theory of collective privacy calculus and impression management, which offer insights into the design of the collective privacy protection function of social network platform service providers.
