We analyze whether midlevel managers in securitized finance were aware of a large-scale housing bubble and a looming crisis in 2004–2006 using their personal home transaction data. We find that the average person in our sample neither timed the market nor were cautious in their home transactions, and did not exhibit awareness of problems in overall housing markets. Certain groups of securitization agents were particularly aggressive in increasing their exposure to housing during this period, suggesting the need to expand the incentives-based view of the crisis to incorporate a role for beliefs.

Purpose The purpose of this paper is a “Q&A interview” conducted by Joanne Pransky of Industrial Robot Journal as a method to impart the combined technological, business and personal experience of a prominent, robotic industry PhD-turned-entrepreneur regarding the evolution, commercialization and challenges of bringing a technological invention to market. Design/methodology/approach The interviewee is Dr Cory Kidd, an inventor, entrepreneur and leading practitioner in the field of human–robot interaction. Dr Kidd shares his 20-year journey of working at the intersection of healthcare and technology and how he applied innovative technologies toward solving large-scale consumer healthcare challenges. Findings Dr Kidd received his BS degree in Computer Science from the Georgia Institute of Technology and earned a National Science Foundation Graduate Research Fellow in Computer and Information Science & Engineering. Dr Kidd received his MS and PhD degrees at the MIT Media Lab in human–robot interaction. While there, he conducted studies that showed the psychological and clinical advantages of using a physical robot over screen-based interactions. While finishing his PhD in 2007, he founded his first company, Intuitive Automata, which created interactive coaches for weight loss. Though Intuitive Automata ceased operations in 2013, Dr Kidd harnessed his extensive knowledge of the healthcare business and the experiences from patient engagement and launched Catalia Health in 2014 with a new platform centered specifically around patient behavior change programs for chronic disease management.

Animportant element of urban planning as it has developed in Europe and North America is the provision of housing for classes of people who are poorly served by private housing markets. In the case of Germany one can trace this activity back to the 1920s, during the middle years of the Weimar Republic, when public authorities began to plan and build housing on a large scale. However, one can also see in the activity of German employers, dating back another half century or more, earlier efforts at urban residential planning for people with modest incomes.

Economic transactions on online peer-to-peer platforms depend on buyers and sellers revealing personal information to facilitate exchanges with the unintended consequence that the information may become a source for discrimination. Using original panel data we show evidence of substantial discrimination against Arab/Muslim hosts in Airbnb’s online rental market in Paris, France. Analysis of 41-months of online transaction data shows a substantial increase in discrimination following large-scale, deadly terrorist attacks in November 2015. Discrimination results in a foregone monthly revenue of at least 106 US dollars for Arab/Muslim hosts in the year before the November 2015 attacks, after which losses increase to at least 178 US dollars. Our results demonstrate the association of mass terrorism with a contraction of a large-scale market of the sharing economy, the cost of which falls disproportionately upon members of an ethnic and religious minority.

AbstractThe complementarity and substitutability between products are essential concepts in retail and marketing. Qualitatively, two products are said to be substitutable if a customer can replace one product by the other, while they are complementary if they tend to be bought together. In this article, we take a network perspective to help automatically identify complements and substitutes from sales transaction data. Starting from a bipartite product-purchase network representation, with both transaction nodes and product nodes, we develop appropriate null models to infer significant relations, either complements or substitutes, between products, and design measures based on random walks to quantify their importance. The resulting unipartite networks between products are then analysed with community detection methods, in order to find groups of similar products for the different types of relationships. The results are validated by combining observations from a real-world basket dataset with the existing product hierarchy, as well as a large-scale flavour compound and recipe dataset.

For many historians, the "Great Man" theory--emphasizing the centrality of powerful leaders in changing history--has (rightly) fallen out of fashion. Less credit is given to leaders; more attention is paid to the average person. Concurrently, for many international relations theorists, the demands of realpolitik and geopolitics are emphasized while the individual personalities of leaders and the collective personalities of cultures are de-emphasized. Yet, while the "Great Man" theory of history is limiting, certain historical events simply cannot be explained without reference to the passions, motives, and personalities of individual leaders. Relatedly, though the competitive desire for resources can explain some wars, the fiercest conflicts are fought not over tangible goods but over abstract ideals. The Second Punic War proves both points: Almost entirely on his own, for reasons related more to culture and ideals than resources, one remarkable man--Hannibal Barca--triggered the ancient world's deadliest world war. The next time resentment over an unfair treaty, bitterness, one driven leader, and clashing ideals would trigger such large-scale conflict would not occur until the Second World War.

Abstract Car rental is a type of business that is engaged in four-wheeled vehicle rental transportation. With the current technological developments greatly affect the quality in the field of car rental services. Several fields that use information technology are education, agriculture and companies have used information technology to facilitate quick, precise and accurate information to the public. The development of technology is not only used for a field or large-scale company, but can be used by various groups of people to support a business they manage. One of the businesses that utilize this information technology is Sakti car rental, which is engaged in transportation for four-wheeled vehicle rental services. Currently, four-wheeled transportation has become a necessity to support the daily mobility of all people. Data management on Sakti Car Rental still uses manual methods which often cause errors. Technological developments also allow the development of a programming language, one of which is the CodeIgniter Framework. Therefore, the author designed a car rental application with a codeigniter framework that aims to make it easier for owners to manage car data, transaction data and to print transaction reports and avoid errors.

BACKGROUND HIV self-testing (HIVST) holds great promise for expanding HIV testing. Yet, large scale data on HIVST behavior is scant. Millions of HIVST kits were sold through e-commerce platforms each year. OBJECTIVE This study aimed to analyze spatiotemporal distribution of the HIVST kit purchasing population (HIVSTKPP) in China. METHODS Deidentified transaction data were retrieved from a leading e-commerce platform in China. Bayesian spatiotemporal analysis was performed to locate hot spots with HIVSTKPP rates. Spatial autocorrelation analysis and space-time cluster analysis were conducted to identify clusters of HIVSTKPP RESULTS Between 1 January 2016 and 31 December 2019, a total of 2.18 million anonyms in China placed 4.15 million orders and purchased 4.51 million HIVST kits online. In each year, the observed monthly HIVSTKPP peaked in December, the month of the World AIDS Day. HIVSTKPP rates per 100,000 population significantly increased from 20.62 in 2016 to 64.82 in 2019. Hot spots were mainly located in municipalities, provincial capitals, and large cities, while high-high clusters and high-demand clusters were predominantly detected in cities along the southeast coast. We found positive correlations between a region’s number of HIV testing facilities, urbanization ratio, and GDP per capita and the HIVSTKPP. CONCLUSIONS Our study identified key areas in larger demands for HIVST for public health policymakers to re-allocate resources and optimize the HIV care continuum. Further research combining spatiotemporal patterns of HIVST with HIV surveillance data is urgently needed to identify potential gaps in current HIV-monitoring practices.
