The fingerprint of the summer 2018 drought in Europe on ground-based atmospheric CO 2 measurements : Atmospheric CO 2 anomaly

During the summer of 2018, a widespread drought developed over Northern and Central Europe. The increase in temperature and the reduction of soil moisture have influenced carbon dioxide (CO 2) exchange between the atmosphere and terrestrial ecosystems in various ways, such as a reduction of photosynthesis, changes in ecosystem respiration, or allowing more frequent fires. In this study, we charact

Beat flicker : a temporal light artefact due to multiple sources of time modulated light

Metrics of temporal light artefacts (TLAs) are tools meant to quantify the magnitude of the impact of temporal modulated light generated by light sources. However, as lighting systems are becoming more and more complex, just assigning a TLA metrics to a light source is not necessarily an easy task. For example, a luminaire containing two drivers operating on slightly different frequencies could ge

Czarniawska, Barbara : Organizational Change – Fashions, Institutions, and Translations

Combining neo-institutionalism, actor network theory, and Gabriel Tarde’s sociology, Czarniawska considers the key driver of organizational change to be imitation but an imitation that rests on translation. Organizations emulate one another by translating fashionable ideas according to their understanding, traditions, needs, and means. As translation in this tradition always entails a transformati

Sensory modality profiles of antonyms

Adjectives that are used to describe sensory experiences are often used to express more than one modality. The adjective sweet, for instance, may primarily be associated with taste (i.e., taste is the dominant modality of sweet), but it can also be used for smell, sound or sight, and possibly even for touch. It has also been shown that some sensory modalities combine more easily than others. Many

Uniform Random Covering Problems

Motivated by the random covering problem and the study of Dirichlet uniform approximable numbers, we investigate the uniform random covering problem. Precisely, consider an i.i.d. sequence ω = (ωn)n≥1 uniformly distributed on the unit circle &x1D54B; and a sequence (rn)n≥1 of positive real numbers with limit 0. We investigate the size of the random set U(ω) := {y ∈ &x1D54B;: ∀N ≫ 1, ∃n ≤ N

Framtiden är inte vad den har varit : Temporaliteter i Sverige - exemplet historieämnets styrdokument 1919-2011

I detta paper behandlas temporalitet utifrån begreppets historiekulturella innebörder. Skolans historieämne rymmer ett spänningsfält av olika typer av temporalitet. Historiestuderande förväntas lära sig om den kronologiska, framåtsyftande historien som indirekt förklarar vår egen tid. Samtidigt återspeglar skolans kursplaner sin samtids behov av minne och orientering. Historia fyller med andra ord

Creative art diaries as a tool to support the development of professional competencies in therapeutic work with clients

Methods to promote professionals’ self-knowledge and affinity for therapeutic alliances may be valuable to facilitate clients’ journeys towards recovery. This article illuminates how the use of creative art diaries can support the development of generic professional competencies in therapeutic work with clients. The methods entailed the construction of a telling case. This case was based on an aut

What drives cryptocurrency returns? A sparse statistical jump model approach

The statistical sparse jump model, a recently developed, robust and interpretable regime-switching model, is used to analyze the factors driving the return dynamics of the largest cryptocurrencies.

What Drives Cryptocurrency Returns? A Sparse Statistical Jump Model Approach

We consider the statistical sparse jump model, a recently developed, robust and interpretable regime switching model, to identify features that drive the return dynamics of the largest cryptocurrencies. The approach simultaneously performs feature selection, parameter estimation, and state classification. Our large number of candidate features comprises cryptocurrency, sentiment, and financial mar

The Sound of Their Wings: Desert Locusts and Conflicts in Africa

Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust i

Planar Dual-polarized Millimeter-wave Shared-aperture Array Antenna with High Band Isolation

A planar millimeter-wave shared-aperture array antenna is proposed and designed in this paper. By composing the substrate integrated waveguide (SIW) and the stripline, the K-band antenna is embedded inside the Ka-band antenna to achieve a smaller size and a low profile by sharing an aperture. The Ka-band antenna radiates through the parallel slot pairs on the surface of the SIW cavities with horiz
