Analytical proofs of classical inequalities between Spearman's and Kendall's

Short analytical proofs are given for classical inequalities due to Daniels [1950. Rank correlation and population models. J. Roy. Statist. Soc. Ser. B 12, 171–181; 1951. Note on Durbin and Stuart's formula for E(r_s). J. Roy. Statist. Soc. Ser. B 13, 310] and Durbin and Stuart [1951. Inversions and rank correlation coefficients. J. Roy. Statist. Soc. Ser. B 13, 303–309] relating Spearman's ρ and Kendall's τ.     

Consistent and rate-optimal density estimation from heteroscedastic data groups

We consider the problem of estimating a density function based on aggregated data where the data group sizes may differ from each other. The reconstruction of the target density can be regarded as a nonlinear statistical inverse problem. We introduce some estimation procedures which are capable to use the observations from all groups by some nonstandard deconvolution techniques. General consistency and rate-optimality under common smoothness constraints are developed. We give some numerical simulations and a data-driven bandwidth selector.

When Queerness Meets Intersectional Thinking: Revolutionizing Parallels,Histories, and Contestations

ABSTRACT

Intuitively distinguishing the myriad of critically informed paradigms requires an in-depth analysis of genealogies, histories, and philosophical underpinnings grounding each paradigm. Despite significant parallels between queer theory and intersectionality theory, the distinction of these two paradigms acts in both complicated and complementary manners that necessitate a dialogue on the contributions emanating from both paradigms to LGBTQ studies. This article targets the following goals: (1) explicate genealogy, history, and philosophical tenets of intersectionality and queer theory; (2) dialogue about the complementary yet complex relationships between the two paradigms; and (3) illustrate the promise of the complex relationship and distinction for LGBTQ studies.     

Workforce/Population,Economy, Infrastructure,Geography, Hierarchy,and Time (WEIGHT): Reflections on the Plural Dimensions of Disaster Resilience

The concept of resilience and its relevance to disaster risk management has increasingly gained attention in recent years. It is common for risk and resilience studies to model system recovery by analyzing a single or aggregated measure of performance, such as economic output or system functionality. However, the history of past disasters and recent risk literature suggest that a single-dimension view of relevant systems is not only insufficient, but can compromise the ability to manage risk for these systems. In this article, we explore how multiple dimensions influence the ability for complex systems to function and effectively recover after a disaster. In particular, we compile evidence from the many competing resilience perspectives to identify the most critical resilience dimensions across several academic disciplines, applications, and disaster events. The findings demonstrate the need for a conceptual framework that decomposes resilience into six primary dimensions: workforce/population, economy, infrastructure, geography, hierarchy, and time (WEIGHT). These dimensions are not typically addressed holistically in the literature; often they are either modeled independently or in piecemeal combinations. The current research is the first to provide a comprehensive discussion of each resilience dimension and discuss how these dimensions can be integrated into a cohesive framework, suggesting that no single dimension is sufficient for a holistic analysis of a disaster risk management. Through this article, we also aim to spark discussions among researchers and policymakers to develop a multicriteria decision framework for evaluating the efficacy of resilience strategies. Furthermore, the WEIGHT dimensions may also be used to motivate the generation of new approaches for data analytics of resilience-related knowledge bases.     

Spatial Barriers and the Formation of Global Art Cities: The Case of Tokyo

This paper addresses a neglected dimension of global cities research: how the idea of economic concentration, its surplus and consequent global influence can be applied to the art world. The research presented here relates to Tokyo as a well‐known example of a global city, advancing existing understandings of Tokyo from the neglected perspective of the arts. Based on qualitative and quantitative research by the author, including cultural and spatial mapping, interviews, ethnographic observations and visual documents, the findings confirm that the role of space and materiality is overlooked in global cities research. The results demonstrate the active contribution and intervention of spatial patterns in the formation of artistic activities. A number of Tokyo's spatial features have an inhibiting effect that shifts artistic activities underground, creating asymmetries in the constitution of symbolic meanings in the city and a failure to openly stimulate artistic practices. As a consequence, Tokyo's vivid art world remains invisible not only to outsiders but to Tokyo itself.     

Gründe und Formen der freiwilligen Nichtnutzung des Internets

This article examines the voluntary and conscious non-usage of the internet by youth and young adults. The study is based on the conceptual framework of de-mediatization. 30 qualitative interviews and a qualitative content analysis have been conducted to identify deficits and disadvantages in the context of everyday internet usage. Eight distinct sets of problems have been found. Furthermore, strategies users develop to handle those problems were investigated. They can be distinguished into strategies of adjusted continued usage and strategies of voluntary partial non-usage. Those complexes of problems that lead to strategies of voluntary self-restraint are the basis for five potential types of boundaries of online communication.     

Implications of Applying the Green Infrastructure Concept in Landscape Planning for Ecosystem Services in Peri-Urban Areas: An Expert Survey and Case Study

This paper investigates how planning experts understand the potential of integrating the concept of green infrastructure in planning practice in Germany. It develops a systematic approach for green infrastructure planning at the landscape scale. Research methods include a web-based survey among German planning experts and geographic information system analysis in the case study region of Hannover. Survey results suggest that the green infrastructure concept is not yet well known in planning practice, and that the potential benefits for planning lie primarily in communication purposes. An approach is developed here that sets priorities for green infrastructure development based on its potentials for creating synergies in the provision of ecosystem services.
