When online retailers allow third-party sellers to place certain products on their platforms, these sellers become not only collaborators but also competitors. The purpose of this study is to compare the differences in price discounts between Third-Party Marketplace (3PM) sellers and Fulfilled by Walmart (FBW) sellers on Walmart.com over time. The results, based on data collected in the form of the daily prices of 54,162 products offered by Walmart during the holiday season, show that the average discount for 3PM sellers is significantly lower than that for FBW sellers. In addition, across product categories, FBW sellers had significantly higher average discounts than 3PM sellers in the electronics, housewares, and toys categories. Furthermore, the level of discount began to increase in early November and peaked around Christmas. Our findings may help retailers manage their dealings with these third-party sellers while also helping consumers to optimize their purchasing decisions.

To date, there have been a number of studies that have examined how policies move from one jurisdiction to another. However, few of these studies have examined the micro-interactive effects of actors. This is necessary to understand how actors shape outcomes over time. The aim of this paper is to engage with this micro-level literature through an empirical study of policy transfer in the field of architectural norms in hospital construction in post-Soviet states. To do this, we generate several theoretical assumptions to link the transfer literature to wider debates in the governance framework. The goal is to discover how the power of actors interacts in the policymaking processes to influence outcomes over time and in light of learning. What we hope to do is bring the interactive and dynamic effects that occur between agents attempting to shape the transfer process back into the transfer picture. The aim is to show that power flows and that these flows alter the shape and outcome of the transfer process.

AbstractSecurity vulnerability in third-party dependencies is a growing concern not only for developers of the affected software, but for the risks it poses to an entire software ecosystem, e.g., Heartbleed vulnerability. Recent studies show that developers are slow to respond to the threat of vulnerability, sometimes taking four to eleven months to act. To ensure quick adoption and propagation of a release that contains the fix (fixing release), we conduct an empirical investigation to identify lags that may occur between the vulnerable release and its fixing release (package-side fixing release). Through a preliminary study of 231 package-side fixing release of npm projects on GitHub, we observe that a fixing release is rarely released on its own, with up to 85.72% of the bundled commits being unrelated to a fix. We then compare the package-side fixing release with changes on a client-side (client-side fixing release). Through an empirical study of the adoption and propagation tendencies of 1,290 package-side fixing releases that impact throughout a network of 1,553,325 releases of npm packages, we find that stale clients require additional migration effort, even if the package-side fixing release was quick (i.e., package-side fixing releasetypeSpatch). Furthermore, we show the influence of factors such as the branch that the package-side fixing release lands on and the severity of vulnerability on its propagation. In addition to these lags we identify and characterize, this paper lays the groundwork for future research on how to mitigate propagation lags in an ecosystem.

Traditionally, public procurement has been associated with the measurement of achieving savings. However, recent research shows that the economic impact of public procurement is not limited only to savings, but by measuring the impact of four capitals—natural, human, social, and economic—on sustainable well-being over time. Ukraine is a country with a very low gross domestic product (GDP) per capita, which exacerbates the problem of the impact of public procurement results on the population’s welfare. Ukrainian public procurement legislation allows customers to apply non-price criteria (the share of non-price criteria cannot be more than 70%), which, together, are taken into account in the formula of the quoted price. The studies show that the effect of the use of non-price criteria depends on the relevance of the method of the evaluation of non-price criteria. The most important non-price criteria for Ukrainian customers by product categories and the methods of their evaluation are analyzed according to the Bi.prozorro.org analytics module. Therefore, it is concluded that the quoted price method, which is used in Ukrainian practice, is not relevant in comparison with the method used in the EU. A survey of the government buyers on the practice of applying non-price criteria was conducted, and the areas of their use were identified.

Abstract Recently, Apple removed access to various device hardware identifiers that were frequently misused by iOS third-party apps to track users. We are, therefore, now studying the extent to which users of smartphones can still be uniquely identified simply through their personalized device configurations. Using Apple’s iOS as an example, we show how a device fingerprint can be computed using 29 different configuration features. These features can be queried from arbitrary thirdparty apps via the official SDK. Experimental evaluations based on almost 13,000 fingerprints from approximately 8,000 different real-world devices show that (1) all fingerprints are unique and distinguishable; and (2) utilizing a supervised learning approach allows returning users or their devices to be recognized with a total accuracy of 97% over time

The increasing prevalence of ageing stepfamilies and the potential of stepchildren to act as a source of support for older parents have increased the interest in long-term intergenerational step relationships. Applying a life-course perspective combined with Simmel’s theorizing on social dynamics, this exploratory study aims to investigate the preconditions for cohesion in long-term intergenerational step relationships. The study is based on interviews with 13 older parents, aged 66–79, who have raised both biological children and stepchildren. Retrospective life-course interviews were used to capture the development of step relationships over time. Interviews were analysed following the principles of analytical induction. The results reveal four central third-party relationships that are important for cohesion in intergenerational step relationships over time, involving: (1) the intimate partner; (2) the non-residential parent; (3) the bridge child; and (4) the stepchild-in-law. The findings have led to the conclusion that if we are to understand the unique conditions for cohesion in long-term intergenerational step relationships, we cannot simply compare biological parent–child dyads with step dyads, because the step relationship is essentially a mediated relationship.

The use of wood and timber products in the construction of buildings is repeatedly pointed towards as a mean for lowering the environmental footprint. With several countries preparing regulation for life cycle assessment of buildings, practitioners from industry will presumably look to the pool of data on wood products found in environmental product declarations (EPDs). However, the EPDs may vary broadly in terms of reporting and results. This study provides a comprehensive review of 81 third-party verified EN 15804 EPDs of cross laminated timber (CLT), glulam, laminated veneer lumber (LVL) and timber. The 81 EPDs represent 86 different products and 152 different product scenarios. The EPDs mainly represent European production, but also North America and Australia/New Zealand productions are represented. Reported global warming potential (GWP) from the EPDs vary within each of the investigated product categories, due to density of the products and the end-of-life scenarios applied. Median results per kg of product, excluding the biogenic CO2, are found at 0.26, 0.24, and 0.17 kg CO2e for CLT, glulam, and timber, respectively. Results further showed that the correlation between GWP and other impact categories is limited. Analysis of the inherent data uncertainty showed to add up to ±41% to reported impacts when assessed with an uncertainty method from the literature. However, in some of the average EPDs, even larger uncertainties of up to 90% for GWP are reported. Life cycle assessment practitioners can use the median values from this study as generic data in their assessments of buildings. To make the EPDs easier to use for practitioners, a more detailed coordination between EPD programs and their product category rules is recommended, as well as digitalization of EPD data.

This chapter traces the rise and fall of electoral Populism in southern Dakota. It begins by examining the transformation of the political field in Dakota Territory, where politics was traditionally organized around the fight for patronage. Excluded from power by the dominant faction of the Republican Party, the leaders of the Farmers’ Alliance turned to third-party politics as a means of waging war on their more elite rivals. I show that support for Populist candidates was closely with Alliance strength, though this relationship weakened over time as the People’s Party took on a life of its own. Major victories were hard to come by in the absence of electoral fusion. The free silver question served as a rallying point for pro-fusion forces, which succeeded in taking power. Unable to manage the distribution of patronage, the fusionist coalition quickly collapsed, taking what was left of the Populist movement with it.
