Based on a decolonial perspective from Latin America, this paper aims to offer a different history of the creation of Brazil’s Consumer Defense Code (CDC), analyzing the process through which Eurocentric influences, especially coming from Consumers International (CI), became present in the development of the code.

A qualitative historical research was developed using marketing amnesia and decolonialism as its theoretical backdrop. Primary and secondary data are used as source of information. Primary data were obtained through interviews with two authors of the CDC. Secondary data were collected from academic articles and books, reports, magazines and consumer organization websites, as well as journalistic articles.

During the drafting of the CDC and after its promulgation, the presence of Eurocentric forces was constant, given the interests of CI and other agents in influencing Brazil’s consumer practices, subordinating them to those of the Global North. This Eurocentric presence was accepted by the Brazilian jurists that drafted the CDC, which led to the incorporation of both laws and bills from Eurocentric countries and the United Nations Guidelines for Consumer Protection into the code.

Such discussions are scarce in marketing, due to the area’s amnestic state regarding the past. While selectively forgetting certain pasts, marketing fails to both acknowledge its tendency to subordinate consumerist actions to those accepted by the Eurocentric world, and to establish analyses that deal with mimetic processes, to minimize asymmetries between companies and consumers, especially in emerging economies, and, even more, dichotomies between the Global North and the Global South.

The complexity and responsibilities of public health make collaboration across multiple levels of government critical. The Centers for Disease Control and Prevention (CDC) effectively uses communities of practice (CoPs) to bring its staff together with partners to share, learn, and address public health problems. This paper aims to focus on CoPs.

The paper assesses the value of CoPs to individual members, their organizations, and their public health domains; assesses whether the CoP Program has improved CDC's relationship with participants in various CoPs; and identifies barriers to participation or success factors that could be applied to the development of new CoPs. Responses from a random sample of active CoP members were analyzed using qualitative data analysis software to identify themes and answer research questions.

The results reveal clear benefits to individual members, their organizations, and public health disciplines including daily work efficiencies, expanded infrastructure, and enhanced relationships between CDC and its public health partners.

This qualitative research analyzed a small number of communities of practice spanning their launch through year 2; further study of a larger sample of public health CoPs, including sustainability factors, would build on this case study's implications.

Public health practitioners seeking a collaborative approach to problem solving will find in this study some useful lessons learned from CDC; readers will be introduced to CDC's CoP Resource Kit and a public health collaboration portal, phConnect.

Well‐facilitated, member‐driven, and highly participative CoPs are valuable tools for fostering collaboration essential to improving the public health system, and should be used more broadly across public health.

Commonly shared logistics services help manufacturing companies to cut down redundant logistics investments while enhance the overall service quality. Such service-sharing mode has been naturally adopted by group companies to form the so-called headquarter-managed centralized distribution center (HQ-CDC). The HQ-CDC manages the common inventories for the group’s subsidiaries and provides shared storage services to the subsidiaries through appropriate sizing, pricing and common replenishment. Apart from seeking a global optimal solution for the whole group, the purpose of this paper is to investigate balanced solutions between the HQ-CDC and the subsidiaries.

Two decision models are formulated. Integrated model where the group company makes all-in-one decision to determine the space allocation, price setting and the material replenishment on behalf of HQ-CDC and subsidiaries. Bilevel programming model where HQ-CDC and subsidiaries make decisions sequentially to draw a balance between their local objectives. From the perspective of result analysis, the integrated model will develop a managerial benchmark which minimizes the group company’s total cost, while the bilevel programming model could be used to measure the interactive effects between local objectives as well as their final effect on the total objective.

Through comparing the numerical results of the two models, two major findings are obtained. First, the HQ-CDC’s profit is noticeably improved in the bilevel programming model as compared to the integrated model. However, the improvement of HQ-CDC’s profit triggers the cost increasing of subsidiaries. Second, the analyses of different sizing and pricing policies reveal that the implementation of the leased space leads to a more flexible space utilization in the HQ-CDC and the reduced group company’s total cost especially in face of large demand and high demand fluctuation.

Several classical game-based decision models are to be introduced to examine the more complex relationships between the HQ-CDC and the subsidiaries, such as Nash Game model or Stackelberg Game model, and more complete and meaningful managerial implications may be found through result comparison with the integrated model. The analytical solutions may be developed to achieve more accurate results, but the mathematical models may have to be with easier structure or tighter assumptions.

The group company should take a comprehensive consideration on both cost and profit before choosing the decision framework and the coordination strategy. HQ-CDC prefers a more flexible space usage strategy to avoid idle space and to increase the space utilization. The subsidiaries with high demand uncertainties should burden a part of cost to induce the subsidiaries with steady demands to coordinate. Tanshipments should be encouraged in HQ-CDC to reduce the aggregate inventory level as well as to maintain the customer service level.

The proposed decision frameworks and warehousing policies provide guidance for the managers in group companies to choose the proper policy and for the subsidiaries to better coordinate.

This research studies the services sharing on the warehouse sizing, pricing and common replenishment in a HQ-CDC. The interactive decisions between the HQ-CDC and the subsidiaries are formulated in a bilevel programming model and then analyzed under various practical scenarios.

This chapter seeks to understand the intersection between eGovernment, social media, and digital inequalities by examining the disparate flow of information during the COVID-19 pandemic. Developed economies are increasingly transitioning to digital interfaces for information dissemination and provision of services. The authors explore the potential of, and challenges facing eGovernment by looking at the use of social media during the COVID-19 pandemic. This chapter employs a case study approach to probe the dynamics of government-initiated efforts at information dissemination through the Center for Disease Control and Prevention’s (CDC) website and social media account on Twitter. The analysis in this chapter uses NodeXL to examine communication roles played by government and non-governmental actors within this slice of the Twittersphere centered around CDC@gov. As the findings demonstrate, non-governmental actors played key roles in the dissemination of public health messaging. The authors analyze these data with an eye to the potential of social media for public health communication and extrapolate that understanding to the use of digital access and social media for the provision of accurate, official information in other circumstances. While the COVID-19 pandemic was a global health crisis, individuals and households face individual or local crises every day. This angle of vision allows the chapter to conclude with recommendations pertaining to government-led information dissemination for the public good during crisis and non-crisis situations alike. In the concluding section, the authors probe the degree to which eGovernment can also address digital inequalities including connectivity, device, and literacy gaps. The authors offer solutions needed for eGovernment initiatives in light of challenges posed by digital inequalities to ensure that digital information sharing and services are accessible to all.

The Centers for Disease Control and Prevention (CDC) is developing and supporting various strategies for emergency bioterrorism preparedness and response. To assist response teams, an informationist participated in preparedness teamwork and developed an electronic reference library with books, journal articles, and CDC documents. This laptop reference library was structured to be completely autonomous but also updatable. The library was tested during an FEMA emergency response exercise that included the informationist librarian. The majority of response team members agreed that both the reference library and librarian were valuable during an emergency response. The exercise emphasized the response team’s need for information and a librarian to find the right information at the right time.

Several emergency public health issues have a tremendous impact on and rely upon close coordination with law enforcement officials. Most interactions involve law enforcement personnel providing security, crowd control, and/or traffic control during public health related incidents. However, as varied chemical and biological threats have emerged over the years, this interaction has increased to include joint investigations between the two disciplines. Certain biological threats, such as pandemics, pose direct threats to the law enforcement agency operations. Understanding the role of public health in emergencies, the overlapping missions, and the threats at all levels allows law enforcement professionals to better prepare themselves and their organizations for coordinating operations and maintaining continuity of law enforcement services.

Detecting and tracking the position of a mobile user has become one of the important subjects in many mobile applications. Such applications use location based services (LBS) for learning and training user movements in different places (cities, markets, airports, stations) along different modes of transport (bus, car, cycle, walk). To date, GPS is the key solution to all LBS but repeated GPS querying is not economical in terms of the battery life of the mobile phone. The purpose of this paper is to study how cheap and energy‐efficient air pressure sensors measuring the altitude could be used, as a complement to the dominant GPS system. The location detection and route tracking task is then accomplished by matching the collected altitude traces with the altitude curves of stored data to find the best matching routes.

The cornerstone of the authors' approach is that a huge amount of route data, collected with GPS devices, is available in various cloud services. In order to evaluate the mechanism of matching routes with altitude data, the authors build a prototype system of crowd‐sourced database containing only altitude data of different routes along different modes of transport. How accurately this stored altitude data could be matched with the collected altitude traces is the key question of this study.

Results show that, within a certain level of accuracy, older repeated routes can be detected from newly tracked altitude traces. Further, the level of accuracy varies depending on the length of path traversed, route curvature, speed of travel and sensor used for tracking.

The new contribution in this paper is to propose an alternative route detection mechanism which minimizes the use of GPS query. This concept will help in retrieving the GPS coordinates of already traversed routes stored in a large database by matching them with currently tracked altitude curves.

The purpose of this paper is to analyse the major development of global citizenship education (GCE) as part of Hong Kong’s secondary school curriculum guidelines, which reveals how it has developed from, first, asking students to understand their responsibilities as citizens to now challenging injustice and inequality in the world. Hong Kong’s curriculum guidelines started to teach GCE as a result of the last civic education guideline issued just before the return of sovereignty to China in 1997. Through documentary analysis, this paper examines how GCE has developed against the backdrop of globalization in Hong Kong’s various secondary school curriculum guidelines.

This study used documentary analysis to examine the developments in the teaching of GCE via Hong Kong’s official secondary school curriculum guidelines. It has studied the aims, knowledge and concepts that are related to GCE by coding the GCE literature and categorizing the findings from the curriculum guidelines.

From the coding and categorizing processes employed, it has been found that GCE in Hong Kong’s official curriculum guidelines has evolved from learning about rights and responsibilities in the 1990s to challenging injustice, discrimination, exclusion and inequality since the late 1990s. Indeed, understanding the world and especially globalization, in terms of comprehending the processes and phenomena through which people around the globe become more connected, has presented challenges for the teaching of civic education. For example, categories of GCE have developed from the simpler expression of concerns about the world to encompass moral obligations and taking action. Similarly, the concerns for the maintenance of peace that were studied initially have since grown and now include work about challenging inequalities and taking action on human rights violations.

This study would have implications for the understanding of GCE in Hong Kong as well as other fast-changing societies in this age of globalization, as civic education curricula need to respond to the impacts of globalization. GCE is an under-researched area, but topics concerning world/international/global affairs have been covered in Hong Kong secondary school curriculum guidelines for several decades.

Prior to the mandate young adults wore masks 42.7% (n = 565) of the time and elderly adults wore masks 81.4% (n = 129) of the time. Also, 56.7% (n = 979) of females and 48.2% (n = 678) of males wore masks. Whereas almost all the observed participants (95.9%, n = 73) who appeared of Asian descent wore masks, individuals perceived as White were far less likely to wear masks with only 47.2% (n = 1,089) wearing masks, and 62.6% (n = 401) of perceived Black individuals wearing masks. After the mask mandate was issued 91.7% (n = 109) of those observed were wearing masks. Mask wearing declined shortly after the CDC guidelines changed to indicate that fully vaccinated people did not need to wear masks indoors.

Understanding demographic differences in mask wearing and responses to policy changes are important for public policy and public health.

This chapter is one of a few that include observational data of actual mask wearing during the COVID-19 pandemic of 2020–2021.

This chapter focuses on the importance of collaboration between university laboratory schools and community partners. The why, what, and how of collaboration within higher education contexts are reviewed, with a focus on the steps required for successful collaboration. The University of Rhode Island Child Development Centers’ collaborative efforts are used to illustrate potential ways collaboration can occur through statewide professional development activities, relationships with state and local public school systems, and relationships with various community groups and agencies. The conclusion is that through collaboration, lab schools can enhance their potential to fulfill their three-part mission of teaching, research, and service, and can strengthen the interconnections among the missions, bridging the gap between theory, research, and practice.
