The social spatial geographies of telecommunications and their infrastructures have long interested scholars in the social sciences, and in urban geography specifically. This paper focuses on data centers. Much effort has been placed in preserving the notion that data centers are ‘clouds’, a terminology that obfuscates the real human geographies of cyberplaces. In this map-making exercise, we visualize the sociopolitical human geographies of data centers, and provoke the reader to consider the impacts that data centers have on residents and their environments. The maps shown in this paper suggest four trends. First, hyperscale data center owners are building near large waterways, signifying a shift in location preferences. Second, data centers stress local administrations, financing, and availability of upstream resources, as hyperscale data centers step up their input needs. Third, data center development is state-led. Fourth the competition for data center industries unfolds across a multi-level governance context. [less ▲]

Wohlbefinden und Gesundheit im Kindheits- und Jugendalter haben in den vergangenen Jahren in der sozialwissenschaftlichen Forschung an Bedeutung gewonnen. Im Vordergrund steht dabei vor allem die Erforschung der Bedingungsfaktoren für die Entwicklung eines „guten“ Wohlbefindens und einer „guten“ Gesundheit bei Kindern und Jugendlichen.

The article examines how the labour market value of education has changed in the context of the expansion of higher education. However, one drawback is understanding how it generates differences between high and low-skilled labour markets, particularly in contexts of high inequality and informality. This could be linked to specific mechanisms by which employers value educational credentials as signalled skills. Using the Luxembourg Income Study (LIS), we analyse trends over two decades in 11 American countries. Our results confirm the previous results for the claim that education has become increasingly positional, compared with the absolute model of education. However, we find that the relative gains in wages for workers with higher levels of education, as the pool of higher education graduates expand over time, increased only slightly in high-skilled occupations, while their relative gains decreased for lower-skilled occupations. This trend is present in both absolute and positional models of education. Moreover, when looking at the structure of labour markets in terms of the linkage between educational credentials and occupational groups, we higher the tertiary education specificity of occupations, the higher the earnings for workers with advantaged positions. These findings are consistent with processes of displacement of low-skilled workers due to increasing competition among highly educated workers, from the positional model of education. [less ▲]

In multi-period environments, the presence of strategic consumers induces monopolist retailers to inter-temporally compete with themselves. Targeting consumers with price-discount coupons is a proposed mechanism to overcome this inter-temporal competition. Targeting consumers with coupons can counteract strategic consumer behavior, but this mechanism cannot completely eradicate the negative implications imposed by the presence of such consumers. Additionally, the quality of information available (regarding the consumers’ valuations) may play an important role in the targeting decisions. Specifically, we illustrate how the retailer may absent completely from targeting efforts when the quality of information and the proportion of strategic consumers are sufficiently low. Lastly, we consider the optimal investment in information solicitation, demonstrating the trade-off between a low investment, which result in low quality of targeting capability, and a high investment which improves the effectiveness of the targeting efforts.

Background To accompany the lifting of COVID-19 lockdown measures, Luxembourg implemented a mass screening (MS) programme. The first phase coincided with an early summer epidemic wave in 2020. Methods rRT-PCR-based screening for SARS-CoV-2 was performed by pooling of samples. The infrastructure allowed the testing of the entire resident and cross-border worker populations. The strategy relied on social connectivity within different activity sectors. Invitation frequencies were tactically increased in sectors and regions with higher prevalence. The results were analysed alongside contact tracing data. Findings The voluntary programme covered 49 of the resident and 22 of the cross-border worker populations. It identified 850 index cases with an additional 249 cases from contact tracing. Over-representation was observed in the services, hospitality and construction sectors alongside regional differences. Asymptomatic cases had a significant but lower secondary attack rate when compared to symptomatic individuals. Based on simulations using an agent-based SEIR model, the total number of expected cases would have been 42·9 (90 CI [-0·3, 96·7]) higher without MS. Mandatory participation would have resulted in a further difference of 39·7 [19·6, 59·2]. Interpretation Strategic and tactical MS allows the suppression of epidemic dynamics. Asymptomatic carriers represent a significant risk for transmission. Containment of future outbreaks will depend on early testing in sectors and regions. Higher participation rates must be assured through targeted incentivisation and recurrent invitation. Funding This project was funded by the Luxembourg Ministries of Higher Education and Research, and Health. [less ▲]

Viruses and plasmids (invasive mobile genetic elements (iMGEs)) have important roles in shaping microbial communities, but their dynamic interactions with CRISPR-based immunity remain unresolved. We analysed generation-resolved iMGE–host dynamics spanning one and a half years in a microbial consortium from a biological wastewater treatment plant using integrated meta-omics. We identified 31 bacterial metagenome-assembled genomes encoding complete CRISPR–Cas systems and their corresponding iMGEs. CRISPR-targeted plasmids outnumbered their bacteriophage counterparts by at least fivefold, highlighting the importance of CRISPR-mediated defence against plasmids. Linear modelling of our time-series data revealed that the variation in plasmid abundance over time explained more of the observed community dynamics than phages. Community-scale CRISPR-based plasmid–host and phage–host interaction networks revealed an increase in CRISPR-mediated interactions coinciding with a decrease in the dominant ‘Candidatus Microthrix parvicella’ population. Protospacers were enriched in sequences targeting genes involved in the transmission of iMGEs. Understanding the factors shaping the fitness of specific populations is necessary to devise control strategies for undesirable species and to predict or explain community-wide phenotypes. [less ▲]
