Towards a Minor Urbanism : Thinking Community without Unity in Recent Makings of Public Space

I DEN DIVERSIFIERADE STADEN, hur kan vi planera och bygga platser för gemenskap som inte är beroende av social och kulturell likhet? I en tid då offentliga samtal förs kring segregation och utan-förskapsområden, aktualiseras frågor kring den fysiska miljöns betydelse för människors lika livsvillkor. I avsaknad av mer genomgripande lösningar kring boendesegregation har de offen-tliga rummen hamnat HOW CAN WE PLAN AND DESIGN FOR community in diverse urban situations? In response to segregation and social fragmentation, public space is increasingly being conceived of as a vehicle for fostering openness towards differences, both in planning practice and theory. Drawing on two recent public space projects – Superkilen in Copenhagen, Denmark, and Jubileumsparken in Gothenburg, Sweden – this thes

Supersonic jets of hydrogen and helium for laser wakefield acceleration

The properties of laser wakefield accelerated electrons in supersonic gas flows of hydrogen and helium are investigated. At identical backing pressure, we find that electron beams emerging from helium show large variations in their spectral and spatial distributions, whereas electron beams accelerated in hydrogen plasmas show a higher degree of reproducibility. In an experimental investigation of

Three-Dimensional Imaging of Beam-Induced Biasing of InP/GaInP Tunnel Diodes

Electron holographic tomography was used to obtain three-dimensional reconstructions of the morphology and electrostatic potential gradient of axial GaInP/InP nanowire tunnel diodes. Crystal growth was carried out in two opposite directions: GaInP–Zn/InP–S and InP–Sn/GaInP–Zn, using Zn as the p-type dopant in the GaInP but with changes to the n-type dopant (S or Sn) in the InP. Secondary electron

Gendered parenthood in the 21st century: Everyday time use and stress in Sweden

This paper examines gender differences in everyday stress among parents in Sweden. Recently, maternal stress has become a public health concern. One of the explanations to why mothers more than fathers get stress-related diagnoses is the unequal division of labor at home. This paper investigates mothers’ and fathers’ time allocation and its association with everyday stress in Sweden, using time di

Sick of squabbling? Household division of labor, disagreement, and ill-health among partnered men and women in Sweden 2000-2010

Individual health and work are closely connected in both positive and negative ways. We investigate the impacts of paid work, unpaid work, and the perception of how work is shared, on subjective and objective health measures in contemporary Sweden. We focus on how gender, workload, and disagreement shape health impacts among partnered men and women. We perform multivariate regression analysis on d

Who cares for mum and dad? Unpaid caregiving and labor supply among the working-age population in Europe

Population ageing affects most European countries, pressurizing pension and care systems. This combination fuels demand for formal and informal care, implying that many, particularly women, are faced with dual responsibilities of paid work and unpaid caregiving. We study the relationship between unpaid caregiving for parents and labor supply (in terms of employment and work hours) among older adul

A tale of 24 counties? Regional variation in female labour force participation in Sweden, 1870-1950

Female labor force participation increased significantly during the 20thcentury, not least in Sweden. In this paper, we investigate the importance of economic, demographic and sociocultural factors in the initial increase and growth of female labor force participationover the course of industrializationusing county-level data and panel regressions.There were important spatial differences across co

‘In Sickness and in Health’: Partners’ Mutual Receipt of Sickness Allowance and Disability Pension in Present-Day Finland

We study married and cohabiting partners’ mutual receipt of sickness allowance and disability pension among people aged 40-65 years in Finland in 1987-2011. Discrete-time hazard models are estimated on population-register based data that include several sociodemographic control variables. We find strong interrelations, irrespective of gender. The risk of receiving sickness allowance is approximate

Effects of target pre-heating and expansion on terahertz radiation production from intense laser-solid interactions

The first experimental measurements of intense laser-driven terahertz (THz) radiation from a solid target which is preheated by an intense pulse of laser-accelerated protons is reported. The total energy of the THz radiation is found to decrease by approximately a factor of 2 compared to a cold target reference. This is attributed to an increase in the scale length of the preformed plasma, driven

Ultrafast control and opto-optical modulation of extreme ultraviolet light

Ultrashort, coherent light pulses in the extreme ultraviolet (XUV) wavelength region are excellent tools for a wide range of experiments. These XUV pulses are in particular used to characterize electron dynamics. Additionally, the high photon energy enables quantum control of short-lived transitions in atoms. These transitions are of interest for ultrafast quantum control as the bandwidth of the c

Twisted Ribbon Aggregates in a Model Peptide System

The model peptides A 8 K and A 10 K self-assemble in water into ca. 100 nm long ribbon-like aggregates. These structures can be described as β-sheets laminated into a ribbon structure with a constant elliptical cross-section of 4 by 8 nm, where the longer axis corresponds to a finite number, N ≠15, of laminated sheets, and 4 nm corresponds to a stretched peptide length. The ribbon cross-section

Pterin-pigmented nanospheres create the colours of the polymorphic damselfly Ischnura elegans

Animal colours commonly act as signals for mates or predators. In many damselfly species, both sexes go through a developmental colour change as adults, and females often show colour polymorphism, which may have a function in mate choice, avoidance of mating harassment and camouflage. In the blue-tailed damselfly, Ischnura elegans, young males are bright green and turn blue as they reach maturity.

Public Space as Commodity: The Social Production of the Hong Kong Waterfront

While there has been a long tradition of public space related land speculation and development, the recent success of the High Line in New York has highlighted the transformative effect carefully designed and curated public spaces can have on the local economy. By prioritising exchange value over use value, governments and developers are exploiting the production of public spaces as a means for fi

Repeated disturbances affect functional but not compositional resistance and resilience in an aquatic bacterioplankton community

Disturbances are believed to be one of the main factors influencing variations in community diversity and functioning. Here we investigated if exposure to a pH press disturbance affected the composition and functional performance of a bacterial community and its resistance, recovery and resilience to a second press disturbance (salt addition). Lake bacterial assemblages were initially exposed to r

Shifts in coastal sediment oxygenation cause pronounced changes in microbial community composition and associated metabolism

BACKGROUND: A key characteristic of eutrophication in coastal seas is the expansion of hypoxic bottom waters, often referred to as 'dead zones'. One proposed remediation strategy for coastal dead zones in the Baltic Sea is to mix the water column using pump stations, circulating oxygenated water to the sea bottom. Although microbial metabolism in the sediment surface is recognized as key in regula
