Vor dem Hintergrund der demokratiegefährdenden Folgen, die eine strukturell verursachte Ungleichheit politischer Partizipation nach sich zieht, hat sich die Partizipationsforschung verstärkt der Frage zugewandt, ob zwischen partizipierenden Bürgern und ihren politisch passiven Mitbürgern systematische Unterschiede hinsichtlich ihrer Ausstattung mit partizipationsrelevanten Ressourcen bestehen. Der Fokus bisheriger empirischer Untersuchungen richtet sich jedoch ausschließlich auf die US-amerikanische Gesellschaft. Allerdings setzen sich auch die deutsche Gesellschaft aus einer Vielzahl von Einwanderergruppen zusammen, die unter der Bezeichnung ‚Personen mit Migrationshintergrund' subsummiert werden können. Laut Mikrozensus besitzen zum gegenwärtigen Zeitpunkt 19,6 Prozent der deutschen Bevölkerung einen Migrationshintergrund. Der Ursprung dieser Einwanderungsbewegung liegt in der sogenannten Gastarbeiterphase, in der zwischen 1952 und 1973 ausländische Arbeitskräfte zur Unterstützung der deutschen Wirtschaft angeworben wurden. Während dieser Ära herrschte in der deutschen Gesellschaft die Annahme, die Arbeitsmigranten würden spätestens nach zwei Jahren aufgrund eines gesetzlich vorgeschriebenen Rotationsverfahrens in ihre Heimatländer zurückkehren. Vor diesem Hintergrund wurde die Frage nach der politischen Integration der Arbeitsmigranten und ihrer Nachkommen in der Integrationsforschung weitgehend vernachlässigt – eine politische Beteiligung der Arbeitsmigranten war gesellschaftlich nicht erwünscht. Obwohl die Mehrheit der Arbeitsmigranten tatsächlich in ihre Heimatländer zurückkehrte, entschied sich ein Teil der Gastarbeiter, ihren Lebensmittelpunkt dauerhaft nach Deutschland zu verlagern und einen Nachzug ihrer Familienangehörigen zu arrangieren. Da aus den Gastarbeitern bleibende Mitbürger geworden sind und ihre in Deutschland geborenen und aufgewachsenen Nachkommen immer zahlreicher werden, kann die Integrationsforschung die Frage nach ihrer politischen Mitwirkung – insbesondere die der zweiten Migrantengeneration – nicht länger ignorieren. In Anknüpfung an die demokratiegefährdenden Folgen, die eine strukturell bedingte, ungleiche Wahrnehmung der politischen Partizipationsrechte nach sich zieht, soll im Rahmen der Magisterarbeit die Frage geklärt werden: Sind in Deutschland geborene Personen der zweiten Migrantengeneration politisch integriert, d.h. weisen sie ein ähnliches Partizipationsverhalten auf wie Deutsche ohne Migrationshintergrund?

This paper introduces the paired comparison model as a suitable approach for the analysis of partially ranked data. For example, the Inglehart index, collected in international social surveys to examine shifts in post-materialistic values, generates such data on a set of attitude items. However, current analysis methods have failed to account for the complex shifts in individual item values, or to incorporate subject covariates. The paired comparison model is thus developed to allow for covariate subject effects at the individual level, and a reparameterization allows the inclusion of smooth non-linear effects of continuous covariates. The Inglehart index collected in the 1993 International Social Science Programme survey is analysed, and complex non-linear changes of item values with age, level of education and religion are identified. The model proposed provides a powerful tool for social scientists.

Urban areas are pivotal to global adaptation and mitigation efforts. But how do cities actually perform in terms of climate change response? This study sheds light on the state of urban climate change adaptation and mitigation planning across Europe. Europe is an excellent test case given its advanced environmental policies and high urbanization. We performed a detailed analysis of 200 large and medium-sized cities across 11 European countries and analysed the cities' climate change adaptation and mitigation plans. We investigate the regional distribution of plans, adaptation and mitigation foci and the extent to which planned greenhouse gas (GHG) reductions contribute to national and international climate objectives. To our knowledge, it is the first study of its kind as it does not rely on self-assessment (questionnaires or social surveys). Our results show that 35 % of European cities studied have no dedicated mitigation plan and 72 % have no adaptation plan. No city has an adaptation plan without a mitigation plan. One quarter of the cities have both an adaptation and a mitigation plan and set quantitative GHG reduction targets, but those vary extensively in scope and ambition. Furthermore, we show that if the planned actions within cities are nationally representative the 11 countries investigated would achieve a 37 % reduction in GHG emissions by 2050, translating into a 27 % reduction in GHG emissions for the EU as a whole. However, the actions would often be insufficient to reach national targets and fall short of the 80 % reduction in GHG emissions recommended to avoid global mean temperature rising by 2 °C above pre-industrial levels. © 2013 Springer Science+Business Media Dordrecht.

Subdermal magnetic implants originated as an art form in the world of body modification. To date an in depth scientific analysis of the benefits of this implant has yet to be established. This research explores the concept of sensory extension of the tactile sense utilising this form of implantation. This relatively simple procedure enables the tactile sense to respond to static and alternating magnetic fields. This is not to say that the underlying biology of the system has changed; i.e. the concept does not increase our tactile frequency response range or sensitivity to pressure, but now does invoke a perceptual response to a stimulus that is not innately available to humans. Within this research two social surveys have been conducted in order to ascertain one, the social acceptance of the general notion of human enhancement, and two the perceptual experiences of individuals with the magnetic implants themselves. In terms of acceptance to the notion of sensory improvement (via implantation) ~39% of the general population questioned responded positively with a further ~25% of the respondents answering with the indecisive response. Thus with careful dissemination a large proportion of individuals may adopt this technology much like this if it were to become available for consumers. Interestingly of the responses collected from the magnetic implants survey ~60% of the respondents actually underwent the implant for magnetic vision purposes. The main contribution of this research however comes from a series of psychophysical testing. In which 7 subjects with subdermal magnetic implants, were cross compared with 7 subjects that had similar magnets superficially attached to their dermis. The experimentation examined multiple psychometric thresholds of the candidates including intensity, frequency and temporal. Whilst relatively simple, the experimental setup for the perceptual experimentation conducted was novel in that custom hardware and protocols were created in order to determine the subjective thresholds of the individuals. Abstract iv The overall purpose of this research is to utilise this concept in high stress scenarios, such as driving or piloting; whereby alerts and warnings could be relayed to an operator without intruding upon their other (typically overloaded) exterior senses (i.e. the auditory and visual senses). Hence each of the thresholding experiments were designed with the intention of utilising the results in the design of signals for information transfer. The findings from the study show that the implanted group of subjects significantly outperformed the superficial group in the absolute intensity threshold experiment, i.e. the implanted group required significantly less force than the superficial group in order to perceive the stimulus. The results for the frequency difference threshold showed no significant difference in the two groups tested. Interestingly however at low frequencies, i.e. 20 and 50 Hz, the ability of the subjects tested to discriminate frequencies significantly increased with more complex waveforms i.e. square and sawtooth, when compared against the typically used sinewave. Furthermore a novel protocol for establishing the temporal gap detection threshold during a temporal numerosity study has been established in this thesis. This experiment measured the subjects’ capability to correctly determine the number of concatenated signals presented to them whilst the time between the signals, referred to as pulses, tended to zero. A significant finding was that when altering the length of, the frequency of, and the number of cycles of the pulses, the time between pulses for correct recognition altered. This finding will ultimately aid in the design of the tactile alerts for this method of information transfer. Preliminary development work for the use of this method of input to the body, in an automotive scenario, is also presented within this thesis in the form of a driving simulation. The overall goal of which is to present warning alerts to a driver, such as rear-to-end collision, or excessive speeds on roads, in order to prevent incidents and penalties from occurring. Discussion on the broader utility of this implant has been presented, reflecting on its potential use as a basis for vibrotactile, and sensory substitution, devices. This discussion furthers with postulations on its use as a human machine interface, as well as how a similar implant could be used within the ear as a hearing aid device.
