Study of Two BeppoSAX Observations of GX 340+0
2006
We present the results of two BeppoSAX broad band (0.1–200 keV) observations of the Z-source GX 340+0 comparing our results to those of a previous observation of the source. From the color–color diagram we selected three zones and extracted the source energy spectrum from each zone. We find that the model, composed by a blackbody plus a Comptonized component, absorbed by an equivalent hydrogen column of ~6 × 10 22 cm −2 , well fits the spectra in the energy range below 30 keV. At higher energies a power law component with photon index of 2.5 is observed. The associated flux decreases going from the horizontal branch to the flaring branch of the Z-track.
Relativistically Smeared Iron Lines in the Spectra of Bright NS LMXB
2009
We present preliminary results of a study on three bright accreting low-mass X-ray binaries hosting a neutron star, based on XMM-Newton observations. These sources (GX 340+0, GX 349+2 and SAX J1808.4-3658) show a broad Fe K alpha iron line in their spectra. This feature can be well described by relativistic line profile in each case; the good spectral resolution of the EPIC/PN and the high statistics spectra allow to put very good constraints on the disk geometry and ionization stage of the reflecting matter.

The agility-control-nexus: A levers of control approach on the consequences of agility in innovation projects
2021
Abstract Recent developments indicate a fast-growing relevance of the agile project methodology in innovation. Besides the benefits, agile projects also pose several challenges. Organizations need to come up with an answer to cope with the inherent risks of agile projects. The adaption of management control mechanisms is key to foster the benefits of agile. However, the ongoing debate on the benefits of control systems for innovation and the harm of control systems for achieving agility creates a nexus. Further research on how to adapt existing mechanisms is required to obtain a better understanding and provide guidance for organizations. Building on Simon's levers-of-control (LOC), this st…
Authoritarian exclusion and laissez‐faire inclusion: Comparing the punishment of men convicted of sex offenses in England & Wales and Norway*
2021
Abstract: Comparative penologists have described neoliberal and social democratic jurisdictions as though they exist at opposite ends of a continuum of inclusion and exclusion, and as though neoliberal states are inactive and social democratic states are invasive. This article, which is based on more than 129 interviews with men convicted of sex offenses in England & Wales and Norway, uses Cohen's work on inclusion and McNeill's typology of rehabilitative forms to complicate this simplistic binary. It argues that the punishment of men convicted of sex offenses in England & Wales was demanding but exclusionary; it imposed strict legal restrictions on these men during and after their imprison…
Restrictions on data-driven political micro-targeting in Germany
2017
The revitalisation of canvassing in recent elections is strongly related to campaigns´ growing possibilities for analysing voter data to gain knowledge about their constituents, identifying their most likely voters and serving up personalised messages through individual conversations. The research literature about political micro-targeting hardly ever focusses on campaigns in parliamentary democracies with strict data protection laws. Based on in-depth expert interviews we introduce a framework of constraints in strategic political communication and reveal several restrictions on the macro, meso and micro levels which hinder the implementation of sophisticated data strategies in Germany. We…
Realizing women´s right to maternal health: A study of awareness of rights and utilization of maternal health services among reproductive age women i…
2019
BackgroundMaternal mortality rates are still unacceptably high in many countries, indicating violation of women´s human right to life and health. Access to adequate information about maternal health rights and available services are essential aspects of realizing women´s right to accessible health care. This study aimed at assessing awareness of the right to access maternal health services among women who had recently given birth, and the association between such awareness and the utilization of maternal health services in two districts in Tanzania.MethodsThis study was cross sectional in design. Interviews were conducted with women who gave birth within one year prior to the survey in two …
Evolutionary processes in the emergence and recent spread of the syphilis agent, Treponema pallidum
2022
Abstract The incidence of syphilis has risen worldwide in the last decade in spite of being an easily treated infection. The causative agent of this sexually transmitted disease is the bacterium Treponema pallidum subspecies pallidum (TPA), very closely related to subsp. pertenue (TPE) and endemicum (TEN), responsible for the human treponematoses yaws and bejel, respectively. Although much focus has been placed on the question of the spatial and temporary origins of TPA, the processes driving the evolution and epidemiological spread of TPA since its divergence from TPE and TEN are not well understood. Here, we investigate the effects of recombination and selection as forces of genetic diver…
Asymptotic properties of incoherent waves propagating in an all-optical regenerators line
2007
International audience; We present an original method to generate optical pulse trains with random time-interval values from incoherent broadband sources. More precisely, our technique relies on the remarkable properties of a line made of cascaded self-phase modulation-based optical regenerators. Depending on the regenerator parameters, various regimes with noticeably different physical behaviors can be reported.
Rewards of reforms: Can economic freedom and reforms in developing countries reduce the brain drain?
2019
The objective of this paper is to investigate the impact of economic freedom on brain drain from developing countries to rich countries. Previous literature on brain drain has examined social, political and economic determinants. However, no study in the literature so far has studied this proposed relationship. We employ the Economic Freedom Index sourced from the Fraser Institute as a proxy for economic freedom and the rate of moderately skilled and highly skilled emigration functions as a proxy for brain drain. Our sample consists of 142 countries covering the period 1990–2010. We estimate the results using a two-way fixed effects regression estimator. The results show that an increase in…
