This article argues that welfare-to-work or activation policies, which have been adopted across a range of OECD countries during the last two decades, do not only have led to changes in the substance of the welfare state but also to transformations in its institutional configuration. This institutional transformation includes the spatial reconfiguration of the welfare state, which has given new roles to the supra-national, national, and sub-national levels of government as well as private actors in the management and creation of labor market policies. By bringing institutions into these debates, this article seeks to expand the literature on welfare-to-work and activation as to date authors working on this topic have said very little about the degree, types, and reasons for the spatial re-configuration of welfare-to-work policies across different states. To fill a gap in the literatures on changes in the welfare state and its territorial configuration in particular, we compare trends in the re-configuration of welfare-to-work policies in Italy, Germany and the United Kingdom. We find that there is a cross-national trend, when it comes to the institutional effects of the implementation of activation. These trends bear a tension between decentralization and centralization, as both central and sub-national levels of government have acquired new responsibilities to implement the activation paradigm.

The globally warm climate of the early Pliocene gradually cooled from 4 million years ago, synchronous with decreasing atmospheric CO2 concentrations. In contrast, palaeoceanographic records indicate that the Nordic Seas cooled during the earliest Pliocene, before global cooling. However, a lack of knowledge regarding the precise timing of Nordic Seas cooling has limited our understanding of the governing mechanisms. Here, using marine palynology, we show that cooling in the Nordic Seas was coincident with the first trans-Arctic migration of cool-water Pacific mollusks around 4.5 million years ago, and followed by the development of a modern-like Nordic Seas surface circulation. Nordic Seas cooling precedes global cooling by 500,000 years; as such, we propose that reconfiguration of the Bering Strait and Central American Seaway triggered the development of a modern circulation in the Nordic Seas, which is essential for North Atlantic Deep Water formation and a precursor for more widespread Greenland glaciation in the late Pliocene.

Developing the social identity theory of leadership (e.g., [Hogg, M. A. (2001). A social identity theory of leadership. Personality and Social Psychology Review, 5, 184-200]), an experiment (N=257) tested the hypothesis that as group members identify more strongly with their group (salience) their evaluations of leadership effectiveness become more strongly influenced by the extent to which their demographic stereotype-based impressions of their leader match the norm of the group (prototypicality). Participants, with more or less traditional gender attitudes (orientation), were members, under high or low group salience conditions (salience), of non-interactive laboratory groups that had instrumental or expressive group norms (norm), and a male or female leader (leader gender). As predicted, these four variables interacted significantly to affect perceptions of leadership effectiveness. Reconfiguration of the eight conditions formed by orientation, norm and leader gender produced a single prototypicality variable. Irrespective of participant gender, prototypical leaders were considered more effective in high then low salience groups, and in high salience groups prototypical leaders were more effective than less prototypical leaders. Alternative explanations based on status characteristics and role incongruity theory do not account well for the findings. Implications of these results for the glass ceiling effect and for a wider social identity analysis of the impact of demographic group membership on leadership in small groups are discussed.

Despite more than 30 years of archaeological research, not a single detailed site report has ever been published for a village site in Torres Strait. This paper presents the results of small-scale excavations at the 700 year old village of Kurturniaiwak on Badu island in mid-western Torres Strait. It represents the first in an ongoing series of systematic excavations of village sites in this part of Torres Strait. Initial results support conclusions of major socio-cultural change for the region as recently proposed by McNiven, and indicate that a major reconfiguration of settlement-subsistence-ritual systems probably took place in western Torres Strait sometime between 600 and 800 years ago.

Pervasive computing applications must be sufficiently autonomous to adapt their behaviour to changes in computing resources and user requirements. This capability is known as context-awareness. In some cases, context-aware applications must be implemented as autonomic systems which are capable of dynamically discovering and replacing context sources (sensors) at run-time. Unlike other types of application autonomy, this kind of dynamic reconfiguration has not been sufficiently investigated yet by the research community. However, application-level context models are becoming common, in order to ease programming of context-aware applications and support evolution by decoupling applications from context sources. We can leverage these context models to develop general (i.e., application-independent) solutions for dynamic, run-time discovery of context sources (i.e., context management). This paper presents a model and architecture for a reconfigurable context management system that supports interoperability by building on emerging standards for sensor description and classification.

Essa pesquisa estuda o papel de grupos religiosos pentecostais junto a migrantes em uma região periférica da cidade de São Carlos no interior de São Paulo. Tomamos como foco de estudo duas igrejas localizadas na região periférica dessa cidade, especificamente do bairro denominado Cidade Aracy. Apresentamos as diferentes fases do desenvolvimento, formação e constituição do bairro em estudo com as configurações assumidas pelo espaço em seu processo de crescimento, desenvolvimento e constituição de periferia. Utilizamos o conceito de periferia urbana vinculado às condições de segregação destacando o componente migratório dos moradores da região em estudo. Analisamos finalmente as características de grupos pentecostais, prestando especial atenção ao papel por eles cumprido na acolhida e na adaptação dos migrantes de outras regiões do país e do Estado. Nosso tema situa-se no contexto maior do mundo urbano como caraterística fundamental da modernidade com as reconfigurações das formas religiosas. Nosso campo teórico combina a sociologia da religião e a sociologia urbana. A pesquisa incluiu observação intensa de campo, mapeamento dos grupos religiosos, aplicação de questionários e entrevistas.

O objeto de estudo desta pesquisa é a Comunidade da Graça, presente há dez anos em São Bernardo do Campo, região do ABC paulista. Analisa-se o lugar da emoção religiosa e sua relação com a educação dos sentidos nesta confraria protestante pentecostal formada majoritariamente por pessoas de classe média, como propiciadora da assimilação de um habitus e de um forte auto-controle individual evidenciando a eficácia do adestramento corporal pela via da religião. Imersa em uma realidade social de muitas mudanças que provocam reconfigurações das religiões, no tipo específico de pentecostalismo estudado nota-se que, na gestão dos bens simbólicos, o ingrediente emocional é o principal acessório a fim de responder às demandas coletivas e individuais deste público religioso. Se há alguns anos a centralidade cúltica do protestantismo pentecostal estava no ouvir a prédica e reviver a experiência do pentecostes cristão, hoje em dia o foco neste é a emoção que deve perpassar todo o culto. O mesmo ocorre nos dois espaços catequéticos privilegiados desta igreja, a saber, a reunião no templo chamada de Conhecendo as Escrituras e os encontros de grupos nos lares. Esta mudança se evidencia, também, nos corpos dos fiéis, pois estes se constróem e modelam-se à realidade social vigente e expressam as experiências vivenciadas neste contexto. A partir da observação dos cultos e reuniões catequéticas desta igreja, analisa-se neste trabalho o modo como a emoção religiosa é construída, difundida e reproduzida, levando-se em consideração as condições sociais e econômicas específicas do grupo religioso em questão.(AU)

We present the prototype tool CADS* for the computer-aided development of an important class of self-* systems, namely systems whose components can be modelled as Markov chains. Given a Markov chain representation of the IT components to be included into a self-* system, CADS* automates or aids (a) the development of the artifacts necessary to build the self-* system; and (b) their integration into a fully-operational self-* solution. This is achieved through a combination of formal software development techniques including model transformation, model-driven code generation and dynamic software reconfiguration.

Product Service Systems (PSSs) emphasize the substitution of products with services. The term “Servitisation” was introduced by Sandra Vendermerwe in the 80s to represent the addition of services to increase a company’s competitive edge. Key to PSS, and Servitisation more generally, is the “informated product”. The informated product enables health monitoring of the product in use and can be key to a workable PSS. This paper reviews the evolution of servitisation and the associated business benefit. It also then reviews the concept of informated product reconfiguration techniques and remote services that enables PSS to be delivered.

Erbium-doped fibre amplifiers (EDFA’s) are a key technology for the design of all optical communication systems and networks. The superiority of EDFAs lies in their negligible intermodulation distortion across high speed multichannel signals, low intrinsic losses, slow gain dynamics, and gain in a wide range of optical wavelengths. Due to long lifetime in excited states, EDFAs do not oppose the effect of cross-gain saturation. The time characteristics of the gain saturation and recovery effects are between a few hundred microseconds and 10 milliseconds. However, in wavelength division multiplexed (WDM) optical networks with EDFAs, the number of channels traversing an EDFA can change due to the faulty link of the network or the system reconfiguration. It has been found that, due to the variation in channel number in the EDFAs chain, the output system powers of surviving channels can change in a very short time. Thus, the power transient is one of the problems deteriorating system performance. In this thesis, the transient phenomenon in wavelength routed WDM optical networks with EDFA chains was investigated. The task was performed using different input signal powers for circuit switched networks. A simulator for the EDFA gain dynamicmodel was developed to compute the magnitude and speed of the power transients in the non-self-saturated EDFA both single and chained. The dynamic model of the self-saturated EDFAs chain and its simulator were also developed to compute the magnitude and speed of the power transients and the Optical signal-to-noise ratio (OSNR). We found that the OSNR transient magnitude and speed are a function of both the output power transient and the number of EDFAs in the chain. The OSNR value predicts the level of the quality of service in the related network. It was found that the power transients for both self-saturated and non-self-saturated EDFAs are close in magnitude in the case of gain saturated EDFAs networks. Moreover, the cross-gain saturation also degrades the performance of the packet switching networks due to varying traffic characteristics. The magnitude and the speed of output power transients increase along the EDFAs chain. An investigation was done on the asynchronous transfer mode (ATM) or the WDM Internet protocol (WDM-IP) traffic networks using different traffic patterns based on the Pareto and Poisson distribution. The simulator is used to examine the amount and speed of the power transients in Pareto and Poisson distributed traffic at different bit rates, with specific focus on 2.5 Gb/s. It was found from numerical and statistical analysis that the power swing increases if the time interval of theburst-ON/burst-OFF is long in the packet bursts. This is because the gain dynamics is fast during strong signal pulse or with long duration pulses, which is due to the stimulatedemission avalanche depletion of the excited ions. Thus, an increase in output power levelcould lead to error burst which affects the system performance.

This thesis presents a large scale numerical investigation of heterogeneous terrestrial optical communications systems and the upgrade of fourth generation terrestrial core to metro legacy interconnects to fifth generation transmission system technologies. Retrofitting (without changing infrastructure) is considered for commercial applications. ROADM are crucial enabling components for future core network developments however their re-routing ability means signals can be switched mid-link onto sub-optimally configured paths which raises new challenges in network management. System performance is determined by a trade-off between nonlinear impairments and noise, where the nonlinear signal distortions depend critically on deployed dispersion maps. This thesis presents a comprehensive numerical investigation into the implementation of phase modulated signals in transparent reconfigurable wavelength division multiplexed fibre optic communication terrestrial heterogeneous networks. A key issue during system upgrades is whether differential phase encoded modulation formats are compatible with the cost optimised dispersion schemes employed in current 10 Gb/s systems. We explore how robust transmission is to inevitable variations in the dispersion mapping and how large the margins are when suboptimal dispersion management is applied. We show that a DPSK transmission system is not drastically affected by reconfiguration from periodic dispersion management to lumped dispersion mapping. A novel DPSK dispersion map optimisation methodology which reduces drastically the optimisation parameter space and the many ways to deploy dispersion maps is also presented. This alleviates strenuous computing requirements in optimisation calculations. This thesis provides a very efficient and robust way to identify high performing lumped dispersion compensating schemes for use in heterogeneous RZ-DPSK terrestrial meshed networks with ROADMs. A modified search algorithm which further reduces this number of configuration combinations is also presented. The results of an investigation of the feasibility of detouring signals locally in multi-path heterogeneous ring networks is also presented.

Self-adaptation enables software systems to respond to changing environmental contexts that may not be fully understood at design time. Designing a dynamically adaptive system (DAS) to cope with this uncertainty is challenging, as it is impractical during requirements analysis and design time to anticipate every environmental condition that the DAS may encounter. Previously, the RELAX language was proposed to make requirements more tolerant to environmental uncertainty, and Claims were applied as markers of uncertainty that document how design assumptions affect goals. This paper integrates these two techniques in order to assess the validity of Claims at run time while tolerating minor and unanticipated environmental conditions that can trigger adaptations. We apply the proposed approach to the dynamic reconfiguration of a remote data mirroring network that must diffuse data while minimizing costs and exposure to data loss. Results show RELAXing Claims enables a DAS to reduce adaptation costs. © 2012 Springer-Verlag.
