- The emergence of new types and new levels of poverty in Sweden has spurred civil society organizations to take a more active role in domestic relief work. Their work is not least directed toward groups of poor with limited access to public welfare in Sweden, in most cases because they are not Swedish citizens. The arrival of groups like the vulnerable EU citizens and undocumented refugees has created a situation where civil society provides emergency relief for groups not eligible for long-term relief from the public sector. A new division of responsibility between civil society and the public sector is therefore being formed, and this division can be explained in terms of rights; the aid organizations are guided by the principles of human rights, while the public sector functions primarily according to social citizenship rights. This article documents the work of the Swedish City Missions, a large aid organization that has become an important actor in poverty relief work in Sweden. A never before conducted survey of 137,000 interventions performed by the Swedish City Missions gives an entirely new insight into the significance of civil society organizations in combating new and old types of poverty in Sweden. Which groups receive which types of aid and what does that tell us about the roles of civil society and the public sector in a rights perspective? The findings show that civil society organizations like the City Missions play a far from marginal role in the Swedish welfare state.

- Color polymorphisms in animals may result from genetic polymorphisms, developmental plasticity, or a combination where some phenotypic components are under strong genetic control and other aspects are influenced by developmental plasticity. Understanding how color polymorphisms evolve demands knowledge of how genetic and epigenetic environmental cues influence the development and phenotypic expression of organisms. Pygmy grasshoppers (Orthoptera, Tetrigidae) vary in color pattern within and among populations. Color morphs differ in morphology, behavior, and life history, suggesting that they represent alternative ecological strategies. Pygmy grasshoppers also show fire melanism, a rapid increase in the frequency of black and dark-colored phenotypes in populations inhabiting fire-ravaged areas. We examined the influence of plasticity on color polymorphism in the pygmy grasshopper Tetrix subulata (L., 1761) using a split-brood design. Individuals were experimentally raised in solitude on either crushed charcoal or white aquarium gravel. Our analyses uncovered no plasticity of either color pattern or overall darkness of coloration in response to rearing substrate. Instead, we find a strong resemblance between maternal and offspring color patterns. We conclude that pygmy grasshopper color morphs are strongly influenced by genetic cues or maternal effects, and that there is no evidence for developmental plasticity of coloration in response to rearing conditions in these insects.

Non-profit organizations in mental health : their roles as seen in research

Tidskriftsartikel (refereegranskat)abstract
- Non-profit organizations (NPO) for mental health are becoming significant actors. Here, their roles in welfare society as understood in research are identified and analyzed. Results from recent research publications on the mental health field are synthesized and categorized in order to find out their origin, theoretical orientation, and view on mental health NPO’s in relation to the public welfare systems. Relevant publications are primarily from the US, empirically oriented, and addressing surveys on both individual and organizational level. NPOs were most often seen as consensus-oriented service organizations, while very few (4%) were seen as conflict-oriented advocates (i.e., anti-professional). It is concluded that these NPOs are most often studied as complements or alternatives to existing public welfare services rather than on their own terms, and that research on the topic lacks more complex theoretical attempts.

Nonlinear Propagation of Optical Pulses and Beams
- 1994
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The propagation of optical beams and pulses under the influence of nonlinear effects is characterized by a rich variety of phenomena and many potentially important applications. We analyse two main topics in this context: nonlinear beam propagation, and nonlinear pulse propagation in optical fibers. The propagation of an optical beam is characterized by diffractive broadening. For Kerr-media, in which the refractive index increases with beam intensity, at a certain intensity, the beam may induce its own waveguide and propagate without broadening. For higher intensities, the nonlinearly induced refractive index causes self-focusing and in some cases even collapsing singularities. We demonstrate in this work that an analytical variational approach describes the dynamics of nonlinear beam propagation very well, in particular with respect to the phase modulation dynamics, which previous approaches are found to describe erroneously. The collapse can be removed by allowing the refractive index to saturate. Beam dynamics in saturable nonlinear media is therefore an important issue. Using the variational method, we manage to reproduce the essential features from numerical simulations, and to give a complete picture of optical beam dynamics in saturable nonlinear media. Another important effect in nolinear media is the modulational instability, which is well-known to break up broad beams into filaments. However, this instability can occur only in nonlinear focusing media. Considering a pulsed beam with a defocusing-in-time and focusing-in-space nonlinearity, we show that temporal breakup is possible due to the spatial instability, despite the fact that a purely temporal modulation is stable.

Novel low-swing bus-drivers and charge-recycle architectures

Konferensbidrag (refereegranskat)abstract
- In this paper novel single-rail low-swing bus-drivers based on schmitt-triggers as voltage level sensors are presented. Two novel 4-transistor schmitt-triggers with non-symmetrical trigger-voltage levels are also proposed. The power dissipation for the single rail low-swing bus-driver is reduced by 48 percent compared to a full-swing driver. Finally, two novel semi-adiabatic charge-recycle circuits are proposed. The power savings for these circuits are 45 and 65 percent, respectively. A data rate of 200 Mbit/s per driver has been reached in a double metal 0.8 μm process.
